Full Text Available In the aim of the study is to determine the institutionalization degree of organized industrial estates and to identify the faced problems and to develop solutions for these problems. By using survey method, information about problems and institutionalization status of organized industrial estates were obtained from managers of the active organized industrial estates. The problems of organized industrial estates are related to the management structure, qualified staff, energy, transportation, regulation and public improvements. Formalization, professionalism, accountability, transparency and social responsibility have been identified as the factors about the institutionalization of organized industrial estates in Turkey according to factor analysis. It could be argued that organized industrial estates in Turkey have an institutional structure and they have institutionalized. However, it could be said that organized industrial estates which operate in 80 cities of Turkey and more than one are in some cities are not at the same level of institutionalization.

This cross-sectional study estimated the prevalence of work days lost due to health problems and associated factors among industrial workers. The study population was a simple random cluster sample of 3,403 workers from 16 to 65 years of age in the city of Salvador, Bahia State, Brazil. Data were collected with individual home interviews. Among industrial workers, one-year prevalence of work days lost to health problems was 12.5%, of which 5.5% were directly work-related and 4.1% aggravated by work. There were no statistically significant differences when compared to other worker categories. Self-perceived workplace hazards, history of work-related injury, and poor self-rated health were associated with work days lost due to work-related injuries/diseases. The findings showed that work days lost are common among both industrial and non-industrial workers, thereby affecting productivity and requiring prevention programs.

Causes of Payment Problems in the New Zealand Construction Industry

Thanuja Ramachandra

2015-03-01

Full Text Available Payment delays and losses persist in the construction industry and continue to be a key concern to industry practitioners. Therefore an exploration of the key causes of payment delays and losses is undertaken in this study with the ultimate objective of seeking mitigating solutions. The study adopted a survey approach using an online questionnaire, administered to practitioners from the New Zealand construction industry, comprising consultants, head contractors and subcontractors. The data obtained was analysed using inferential statistical techniques, including comparing means and factor analysis. Factor analysis enabled clustering of the inter-related causes of payment delays and losses in order to find reduced number of causes. Accordingly, the study found that payment problems mainly relate to contractual issues, financial strength of industry players, disputes, short-comings of payment processes and ‘domino effects’. Among them, the financial strength of critical industry players was considered central to payment problems. The study concludes that any solution to these problems must address these primary causes, as a rational starting point. Thus procuring a feasible form of financial security at the outset of a project, and the pre-qualification of the financial status of critical project participants, were found to be significant in the mitigation of construction payment risks.

Zhou, Qixing

2005-06-01

Environmental pollution and its solicitation in ecological problems of old industrial and mining areas have become a worldwide technological puzzle restricting sustainable economic and social development. But, the definition and category of old industrial and mining areas is still disputed as an important concept. In this paper, the concept of old industrial and mining area was discussed in theory, and, proceeded with analyzing the complexity of current situation and environmental pollution problems of old industrial and mining areas in China, more keystone attention was paid to the secondary pollution problems from old industrial and mining areas as an important frontier of science. On the basis of expounding the complexity and characters of environmental pollution in old industrial and mining areas, it was suggested that as two key scientific problems in environmental sciences and ecology, the formation mechanisms and control technology of secondary pollution in old industrial and mining areas and the responses of new-type diseases to environmental pollution based on molecular ecotoxicology should be systematically studied on the national scale, and be an important component of environmental protection strategy in China in the future.

Long-term problem for the nuclear industry

International Nuclear Information System (INIS)

Norman, C.

1982-01-01

Dismantling of the 24-year-old Shippingport atomic power station over the next two years will test whether the nuclear industry can safely dispose of high-level radioactive facilities. Recent findings that some components will remain radioactive longer than anticipated may require dismantling instead of the permanent entombment the industry was planning. The five-year dismantlement will cost $40 million and generate 11,700 cubic meters of radioactive waste. Larger reactors will be even more costly. Current regulations require utilities to choose between dismantlement, safe storage, or entombment of contaminated materials. Each has its problems, but the industry objects to an evolving policy for dismantling and an accompanying requirement for a segregated decommissioning fund that would be set aside before a reactor begins operating or during plant lifetime. The latter would require an adequate insurance mechanism to cover premature shutdown

Problems of the regional energy supply industry touching directly the energy supply utilities (e.g. territorial reform, power prices) are discussed. In a survey on the overall energy situation in the FRG as seen by energy supply utilities, the following conclusions are drawn: 1) The electricity supply industry is in the favourite position to make the required structural changes by utilizing primary energy for generating electric power. It offers - via electric energy - an effective opportunity for substituting oil. 2) The electricity supply industry alone will be in a position to use nuclear energy during the next few decades. A decision in favour of nuclear energy must not be at disposal to make oneself momentarily politically popular. This indispensable decision results exclusively from our responsibility for the future of our national economy and thus our society. (orig./HP) [de

Wang, Ching-Wen; Lin, Po-Chang; Sha, Chyuan

2014-06-01

To support employees' work and health, organizations should help employees cope with common problems. Previous studies have focused primarily on work-related problems across multiple industries rather than on evaluating industry-specific issues. Here, two approaches identified common work and non-work employee problems in the technology industry with the strongest correlations with psychosomatic health and life satisfaction. Study 1 used questionnaires to identify the problems that were perceived as the most frequent by lower-level employees (N = 355) working in the technology industry. Study 2 evaluated employees' coping behaviors by analyzing (with permission) counseling records collected from an employee assistance service company (N = 276). Employees reported a variety of problems; work problems were the only problems (of the top 5 problems) reported in both studies. Several problems emerged in the counseling records (e.g., legal issues, career development, family and marriage problems, and emotional problems) but not in the surveys. Future research should apply these observations to develop scales for measuring employee stressors.

Ionizing Radiation as an Industrial Health Problem

Science.gov (United States)

Trewin, R. B.

1964-01-01

Ionizing radiation, first as x-rays, later in natural form, was discovered in Europe in the late 1890's. Immediate practical uses were found for these discoveries, particularly in medicine. Unfortunately, because of the crude early equipment and ignorance of the harmful effects of radiation, many people were injured, some fatally. Because of these experiences, committees and regulatory bodies were set up to study the problem. These have built up an impressive fund of knowledge useful in radiation protection. With the recent development of the peaceful uses of atomic energy, sources of radioactivity have appeared cheaply and in abundance. A rapidly growing number are finding industrial application. Because of their potential risk to humans, the industrial physician must acquire new knowledge and skills so that he may give proper guidance in this new realm of preventive medicine. The Radiation Protection Program of one such industry, the Hydro-Electric Power Commission of Ontario, is summarized. PMID:14105012

2016-01-01

Full Text Available This paper presents an efficient approach for solving a real two-dimensional irregular cutting stock problem in ship building industry. Cutting stock problem is a common cutting and packing problem that arises in a variety of industrial applications. A modification of selection heuristic Exact Fit is applied in our research. In the case referring to irregular shapes, a placement heuristics is more important to construct a complete solution. A placement heuristic relating to bottom-left-fill is presented. We evaluate the proposed approach using generated instance only with convex shapes in literatures and some instances with nonconvex shapes based on real problem from ship building industry. The results demonstrate that the effectiveness and efficiency of the proposed approach are significantly better than some conventional heuristics.

Full Text Available The article focuses on the consequences of industrialization of the western region of the Ukrainian SSR – large-scale construction industry provided jobs for the active population of the region, led to the expansion of infrastructure of settlements and towns, strengthened social sphere and became a positive factor for the development of the western regions of Ukraine. However, due to the increased production capacity natural resources got depleted. The ability of ecosystems to self-healing and self-cleaning was not taken into account, which caused devastating impact on nature and human health. Uncontrolled industrial pollution of air, water and land resources became a common phenomenon for the urbanized western region. Promoting environmental knowledge and declaration of achievement of significant progress in official documents gave no mechanisms to solve environmental problems. Overcoming the difficulties of the past is connected with the Ukraine had been being a part of the USSR. The leading place took environmental issues. Poor environmental condition of the whole country was not only caused by the world’s largest man-made disaster on the Chernobyl nuclear plant in April 1986, but also intensive industrialization and collectivization. Full conversion of the economy and agriculture in the middle of the last century led to the growth of anthropogenic impact on the environment. A radical break steady of socio-political and socio-economic life took place in western Ukraine in the second half of the twentieth century. Party-Soviet government in a short time made a «socialist transformation» and social progress was considered only as a means to achieve this goal. A number of issues concerning environmental protection, safety of life, were ignored. Environmental protection, regulation of environmental and economic activities, guaranteeing rights of Ukrainian citizens to environmental safety is currently among the national priorities of the

Problems in steel industry for power engineering

International Nuclear Information System (INIS)

Dolbenko, E.T.; Kryanin, I.R.

1979-01-01

The main problems of steel industry in power engineering are considered. The effect of charge materials upon steel quality is analyzed. Radical dicision of the problem is the ensurance of power engineering plants with high quality original charge materials, which are quite pure according to impurities such as: iron melted from metallized charge or prereduced pellets. The usage of such materials considerably improves the complex of technological and service properties and structure of large responsible products: vessels of the reactor core, especially large shafts and others. For the most responsible power engineering dies it is necessary to smelt steel of 150-200 tons and above. The main direction of steel melting industry is quality steel melting in large 150-200 tons arc furnaces which are equipped with magnetic stirrer installations. It is marked that the branch of power engineering is equipped with unique installations of out-of-furnace steel refining. It is shown that further increase in the metal quality is possible when vacuum and electroslag technique of melting is used. It permits to reduce considerably the amount of sulphur, gases, nonmetallic inclusions, to increase the metal density, to remove zonal segregation in large steel ingots. The main problem in the field of usage of material, produced by new melting methods is the expansion of the product nomenclature and the development of technical conditions, reflecting the increase in material properties as a result of new technique application. Importance of development and introduction of new automation and testing methods in metallurgical processes is marked

Electric utility strategies and the emerging industry structure - Part 1

Motupalli, S.

1991-01-01

The electric utility industry is our most capital intensive industry by far. Over the past few decades, socioeconomic and technological forces have been quietly revolutionizing the way the industry conducts itself. During the 1980s, these changes have been particularly intense, often catching both regulators and regulated ill-prepared to develop effective and profitable strategies to deal with such change. Much has already been written about these changes: independent power producers, competitive procurement of resources, incentive-based regulation, the benefits of affiliated company structures, mergers and consolidation, customer energy conservation, and marketing strategy development are all currently highly popular article and seminar topics. The author's object in this two-part series is to facilitate development of a decision framework to put these various changes in perspective, to help develop effective strategies through better focused and equipped planning methodologies. Gaining an understanding of the role, strengths and weaknesses of the various players in an industry and the structural constraints in which they operate is a necessary precursor to developing effective operating strategies to deal with change or to manipulate industry forces in your favor. Michael Port's popular five forces model provides a convenient way to develop such an understanding. It provides a way to map the industry forces driving profitability, through a review of the strengths, weaknesses and leverage of: current industry players, suppliers to the industry, customers for the industry's product, new entrants into the market, and substitute products providing equal or better value. Part 1 of this series reviews each of these five forces along some key dimensions to determine their direction of change or influence, and whether this change impacts a utility's competitive position favorably or unfavorably

Defect assessment in nuclear components: R and D related to industrial problems - synthesis of the research, training and teaching activities

International Nuclear Information System (INIS)

Marie, St.

2007-06-01

Nuclear industry pays a particular attention to structures integrity problems: well-aware of the possible catastrophic consequence of a major accident, everything is carried out to minimise the risk of such a situation. From the design, and during all the operating life of the plant, a high level of safety is required and checks by the safety authorities, on the basis of reports made by the operator. These two entities ask for R and D activities to support the improvement of the knowledge of the phenomena already identified (as in the case of the vessel of the PWR) or to bring some element of understanding to situation not considered yet, up to the first incident (as in 1998 with the fatigue problems in the thermal mixing zone, at the origin of the Civaux arrest). Among the CEA teams concerned with these problems, the Laboratory of the Structures Integrity and of Normalisation aims to study the integrity problems in metallic nuclear structures leaning on exceptional experimental means: the RESEDA platform allows the realisation of large-scaled tests on analytical tests (representative of analysed phenomena) to reproduce the industrial situation, linked to various and accurate equipment for the measures and the analyses. Three industrial thematics represent to main part of my research activities at CEA in the fracture mechanics field: - the industrial case of the PWR vessel is related to brittle fracture of the ferritic steels, - the piping components, related to ductile tearing and fracture in the brittle-to-ductile domain, - the high temperature fracture mechanics for the components submitted to very complex loadings.

FORECASTING OF PRODUCTION OUTPUT FOR LIGHT INDUSTRY ENTERPRISES WITH PURPOSE TO DETERMINE THEIR POWER RESOURCES REQUIREMENTS. Part 1

Directory of Open Access Journals (Sweden)

V. N. Romaniuk

2015-01-01

Full Text Available The paper presents an interest for those specialists who are involved in solution of efficiency problems in light industry of Belarus as one of the significant industries that forms an economic situation in the Republic, its export potential and social climate. It is extremely relevant for the Belarusian enterprises to reduce production costs in order to preserve and strengthen positions in the light industry market. Operating capacities for production of natural, synthetic textile and knit-wear materials and their subsequent treatment are in many respects unjustifiably energy intensive. Nowadays the only acceptable solution of the problem for reduction of production costs is to decrease its energy component. Such approach requires transition to creation of modern heat and power supply systems at heat technology enterprises.The most important sub-system of the enterprises is own combined production of energy flows of secondary electrical and heat energy, freeze. There is a complex of problems that arise during designing process of tri-generation unit. One of the most important problems presupposes determination of a base load demand and capacity of every energy flow generated by an energy source. The solution is directly related to production output, which in its turn is determined by the requirements of sales markets. Due to various reasons the markets have their own specificity for the enterprises under consideration. It is proposed to use statistical methods for searching requirements. In this connection it is necessary to take into account industry development rate (pre-determined by State Programs, Plans, Governmental solutions, including directive instructions, production volumes of competitive goods and actual goods situation on the sales market.The paper presents the first part of the executed complex investigations which are directed on the development of scientifically-substantiated proposals for higher energy efficiency of the

Problems of power-heat-coupling in industry

Energy Technology Data Exchange (ETDEWEB)

1977-03-01

The coupled heat and electric power supply from counter-pressure and partly also from extraction-condensing plants theoretically offers the best possibilities for saving energy in comparison to other measures which reduce the primary energy employed at equal useful energy. A basic requirement for the use of this principle of power-heat coupling is a somewhat simultaneous need of heat and electrical energy as well as a relatively short distance between production point and consumption point, since the transfer ability of the heat is limited due to the considerable cost of the transportation system. Numerous industrial enterprises offer favorable conditions for the use of power-heat coupling. Because of the existing legal and contract rights restraints, the incentive for a free development of industrial power-heat coupling with the aim of saving energy is strongly weakened. Therefore a new order to road rights is nececessary, which would make possible the construction and operation of common plants for several industrial operations and which would insure the right to lay industrial energy lines in public roads where reasonably possible. It has been proven necessary to make it the duty of the cartel authorities to orient their examinations of price regulations for auxiliary and reserve electric power supply solely on the objective electricity economy facts, but not on so-called advantageous points of view. Ultimately the regulation for common use of the utilities own piping system for the purpose of saving and piping free energy and free power from its own plants can be reasonably necessary in the utilities realm, if free agreements between the utility and the industry are not enough in this question.

Problems the chemical industry of Japan faces and future prospects

Energy Technology Data Exchange (ETDEWEB)

Ishida, Shin' ichi

1989-01-01

Industry proceeds for the fiscal 1988 are expected to increase remarkably as they did in the previous year with 4.9% increase in revenue and 18.8% increase in profit (ordinary profit) from the previous year. The conditions of material industry are especially favorable and chemical industry is also expected to prosper as it did in the previous year. Problems this prospering chemical industry is facing are introduced in this report. Firstly, it is necessary to improve productivity by adopting more information and promoting factory automation in order to strengthen competition. The future of chemical industry depends on the introduction of information. Secondly, as demands of users are becoming more diversified, and cycles of products shorter, shortening of development terms is essential. It is necessary, therefore, to predict the demands of users in advance and seek after custom products. Thirdly, selection of product bases is required; it might be necessary to consider producing some product items abroad. Moreover, it is desirable to increase investments in investigation and pursue creativity putting much stress on basic investigations. 2 figs., 11 tabs.

Computerization in industry causes problems for people with reading and writing difficulties (dyslexia).

Science.gov (United States)

Knutsson, A

1986-01-01

For 10 years computerization in industry has advanced at a rapid pace. A problem which has not received attention is that of people with reading and writing difficulties who experience severe problems when they have to communicate with a computer monitor screen. These individuals are often embarrassed by their difficulties and conceal them from their fellow workers. A number of case studies are described which show the form the problems can take. In one case, an employee was compelled to move from department to department as each was computerized in turn. Computers transform a large number of manual tasks in industry into jobs which call for reading and writing skills. Better education at elementary school and at the workplace in connection with computerization are the most important means of overcoming this problem. Moreover, computer programs could be written in a more human way.

Dornburg, Courtney C; Stevens, Susan M; Hendrickson, Stacey M L; Davidson, George S

2009-08-01

An experiment was conducted to compare the effectiveness of individual versus group electronic brainstorming to address difficult, real-world challenges. Although industrial reliance on electronic communications has become ubiquitous, empirical and theoretical understanding of the bounds of its effectiveness have been limited. Previous research using short-term laboratory experiments have engaged small groups of students in answering questions irrelevant to an industrial setting. The present experiment extends current findings beyond the laboratory to larger groups of real-world employees addressing organization-relevant challenges during the course of 4 days. Employees and contractors at a national laboratory participated, either in a group setting or individually, in an electronic brainstorm to pose solutions to a real-world problem. The data demonstrate that (for this design) individuals perform at least as well as groups in producing quantity of electronic ideas, regardless of brainstorming duration. However, when judged with respect to quality along three dimensions (originality, feasibility, and effectiveness), the individuals significantly (p industrial reliance on electronic problem-solving groups should be tempered, and large nominal groups may be more appropriate corporate problem-solving vehicles.

Critique of the electricity industry. Research report ERG 013. [In United Kingdom

Energy Technology Data Exchange (ETDEWEB)

1976-03-01

The studies described in this report were begun in October 1975 and had the aim of examining the future role of the electricity industry in the light of the changes in fuel prices and the government's ''Save It'' campaign. As the study proceeded, it became obvious that the electricity industry was facing a crisis which threatened a number of government policies. The essence of this crisis is a declining demand for electricity coupled with an installed capacity 55 percent greater than required to meet peak demand. The most obvious solution to the electricity industry's problems is to promote vigorously electricity sales so as to improve its revenue and maintain the growth in number of power stations. This is clearly in conflict with the ''Save It'' campaign and likely to increase the U.K.'s consumption of oil. The alternative solution, namely to raise the price of electricity and drastically reduce orders for new power stations, is in conflict with the government's policies aimed at curbing inflation and unemployment. Thus the study was enlarged to encompass not only the role of electricity in a national fuel policy but also to examine policies which would alleviate the worst effects of the immediate crisis without prejudicing either short-term economic objectives or longer-term fuel policies. Part 2, Technical Factors, explains technical issues involved in the discussions. Part 3, Industry Problems, sets out the problems as seen by the industry and the explanation of how the industry came to its present position. Part 4, Consumer Problems, explains the nature of customers problems and how government services and pricing policies could be used to alleviate these. Part 5, Government Policy, shows the need for an integrated fuel policy and the general direction that the studies suggest this policy should take. Conclusions are summarized in Part 6. (MCW)

Zaruba, Natalya; Fraltsova, Tamara; Snegireva, Tatyana

2017-11-01

The article is written based on some results of the long-term scientific research of the problem related to the urgent need to find the ways of training personnel for the innovative coal industry in the higher education system. This is due to the fundamental changes in the Russian social and economic conditions: the change in the social system and the owner of the coal industry, the emergence of new technologies in the field of coal mining and processing, and in the management of these processes. At the same time, the system of training specialists for the coal industry in the higher education institutions has largely remained unchanged: technologies and principles of training, scientific approaches and concepts take little account of the changed situation, traditional views of specialists work-ing in the university continue to dominate innovative ideas. Many innovations, especially related to technology and the principles of education, struggle to make their way into the higher education system. The article substantiates the urgency of the problem of training personnel for the innovative coal industry in the higher education system, as well as the importance of scientific analysis of the problem in order to find the ways to solve it.

An inverse problem approach to pattern recognition in industry

Directory of Open Access Journals (Sweden)

Ali Sever

2015-01-01

Full Text Available Many works have shown strong connections between learning and regularization techniques for ill-posed inverse problems. A careful analysis shows that a rigorous connection between learning and regularization for inverse problem is not straightforward. In this study, pattern recognition will be viewed as an ill-posed inverse problem and applications of methods from the theory of inverse problems to pattern recognition are studied. A new learning algorithm derived from a well-known regularization model is generated and applied to the task of reconstruction of an inhomogeneous object as pattern recognition. Particularly, it is demonstrated that pattern recognition can be reformulated in terms of inverse problems defined by a Riesz-type kernel. This reformulation can be employed to design a learning algorithm based on a numerical solution of a system of linear equations. Finally, numerical experiments have been carried out with synthetic experimental data considering a reasonable level of noise. Good recoveries have been achieved with this methodology, and the results of these simulations are compatible with the existing methods. The comparison results show that the Regularization-based learning algorithm (RBA obtains a promising performance on the majority of the test problems. In prospects, this method can be used for the creation of automated systems for diagnostics, testing, and control in various fields of scientific and applied research, as well as in industry.

Impact of industrialization on environment

International Nuclear Information System (INIS)

Anwar, S.M.; Saqi, S.K.

2005-01-01

The positive economic and social results of industrial growth have been accompanied by serious environmental degradation, however, as well growing threats to health from occupational hazards. To some extent, these problems are analogous to those of early industrial Europe. In the 19th century, the shift from a rural, agrarian society to an urban, industrial society initially involve widespread social and economic disruption, unemployment, homelessness, pollution, and increased exposure to health hazards both at work and at home. Many of these same problems characterize cities in the developing world today. As part of this growth, industrial wastes are going in quantity and becoming more varied, more toxic, and more difficult to dispose off or degrade. Densities in cities where much of the industrial production is located for surpass those in developed countries, so the number of people exposed to pollutants is potentially much greater. (author)

Risk in Nuclear Industry. Liability for Nuclear Damage. Status of the Problem in the Russian Federation

Kovalevich, Oleg M.; Gavrilov, Sergey D.; Voronov, Dmitry B.

2001-01-01

Russia is one of a few nuclear power states obtaining the whole number of nuclear fuel cycle (NFC) components - from mining of uranium and on-site electricity production, from NPP spent nuclear fuel processing and extracted fissile materials and radionuclides, which are available in industry, in medicine and in other relevant areas, to radioactive waste processing and disposal. For this reason it is very important to solve the problem of nuclear fuel cycle safety as it is a single system task with an adequate approach for all cycle components. The problem is that NFC facilities are technologically various and refer to different industries (mining, machinery engineering, power engineering, chemistry, etc.). Besides, the above facilities need the development of various scientific bases. The most NFC facilities is directly connected with peaceful use of nuclear energy and with military nuclear industry, as the defense orders stimulated the development of NFC. The specific attention to safety problems at the beginning of nuclear complex foundation adversely affected the state attitude towards the risk in nuclear industry, it has left the traces at present. In our paper we touch upon the problems of risk and the liability for nuclear damage for the third persons. The problems of nuclear damage compensation for nuclear facilities personnel and for the owners (operating organizations) are beyond our subject

A consideration is given to problems associated with operating nuclear power plants in many countries and building new NPPs. A special attention is given to safety operation of nuclear plants, to reprocessing and transportation of spent nuclear fuel as well as to radioactive waste disposal. In connection with difficulties in solving the above-mentioned problems a proposition is made to resume work on designing NPPs with the use of nuclear liquid salt reactors based on molten fuel fluoride salts. Advantages and disadvantages of fuel compositions of LiF-BeF 2 -UF 4 -(ThF 4 ) are listed. It is recommended that fundamental studies be carried out into such compositions as KF + CsF; BaF 2 + KF + NaF; AlF 3 + Na 3 AlF 6 , eutectics on the basis of tin and zinc fluorides and their complex salts of M x Sn(Zn)F y . An international program is suggested to be developed to find some way out of crisis of nuclear power industry using research efforts in homogeneous liquid salt nuclear underground reactors with a U(233)-Th fuel cycle [ru

A Mathematical Model for the Industrial Hazardous Waste Location-Routing Problem

Directory of Open Access Journals (Sweden)

Omid Boyer

2013-01-01

Full Text Available Technology progress is a cause of industrial hazardous wastes increasing in the whole world . Management of hazardous waste is a significant issue due to the imposed risk on environment and human life. This risk can be a result of location of undesirable facilities and also routing hazardous waste. In this paper a biobjective mixed integer programing model for location-routing industrial hazardous waste with two objectives is developed. First objective is total cost minimization including transportation cost, operation cost, initial investment cost, and cost saving from selling recycled waste. Second objective is minimization of transportation risk. Risk of population exposure within bandwidth along route is used to measure transportation risk. This model can help decision makers to locate treatment, recycling, and disposal centers simultaneously and also to route waste between these facilities considering risk and cost criteria. The results of the solved problem prove conflict between two objectives. Hence, it is possible to decrease the cost value by marginally increasing the transportation risk value and vice versa. A weighted sum method is utilized to combine two objectives function into one objective function. To solve the problem GAMS software with CPLEX solver is used. The problem is applied in Markazi province in Iran.

Biopharmaceutical manufacturing comprises of multiple distinct processing steps that require effective and efficient monitoring of many variables simultaneously in real-time. The state-of-the-art real-time multivariate statistical batch process monitoring (BPM) platforms have been in use in recent years to ensure comprehensive monitoring is in place as a complementary tool for continued process verification to detect weak signals. This article addresses a longstanding, industry-wide problem in BPM, referred to as the "Low-N" problem, wherein a product has a limited production history. The current best industrial practice to address the Low-N problem is to switch from a multivariate to a univariate BPM, until sufficient product history is available to build and deploy a multivariate BPM platform. Every batch run without a robust multivariate BPM platform poses risk of not detecting potential weak signals developing in the process that might have an impact on process and product performance. In this article, we propose an approach to solve the Low-N problem by generating an arbitrarily large number of in silico batches through a combination of hardware exploitation and machine-learning methods. To the best of authors' knowledge, this is the first article to provide a solution to the Low-N problem in biopharmaceutical manufacturing using machine-learning methods. Several industrial case studies from bulk drug substance manufacturing are presented to demonstrate the efficacy of the proposed approach for BPM under various Low-N scenarios. © 2018 Wiley Periodicals, Inc.

Optimal recombination in genetic algorithms for combinatorial optimization problems: Part II

Directory of Open Access Journals (Sweden)

Eremeev Anton V.

2014-01-01

Full Text Available This paper surveys results on complexity of the optimal recombination problem (ORP, which consists in finding the best possible offspring as a result of a recombination operator in a genetic algorithm, given two parent solutions. In Part II, we consider the computational complexity of ORPs arising in genetic algorithms for problems on permutations: the Travelling Salesman Problem, the Shortest Hamilton Path Problem and the Makespan Minimization on Single Machine and some other related problems. The analysis indicates that the corresponding ORPs are NP-hard, but solvable by faster algorithms, compared to the problems they are derived from.

Industrial waste recycling strategies optimization problem: mixed integer programming model and heuristics

Science.gov (United States)

Tang, Jiafu; Liu, Yang; Fung, Richard; Luo, Xinggang

2008-12-01

Manufacturers have a legal accountability to deal with industrial waste generated from their production processes in order to avoid pollution. Along with advances in waste recovery techniques, manufacturers may adopt various recycling strategies in dealing with industrial waste. With reuse strategies and technologies, byproducts or wastes will be returned to production processes in the iron and steel industry, and some waste can be recycled back to base material for reuse in other industries. This article focuses on a recovery strategies optimization problem for a typical class of industrial waste recycling process in order to maximize profit. There are multiple strategies for waste recycling available to generate multiple byproducts; these byproducts are then further transformed into several types of chemical products via different production patterns. A mixed integer programming model is developed to determine which recycling strategy and which production pattern should be selected with what quantity of chemical products corresponding to this strategy and pattern in order to yield maximum marginal profits. The sales profits of chemical products and the set-up costs of these strategies, patterns and operation costs of production are considered. A simulated annealing (SA) based heuristic algorithm is developed to solve the problem. Finally, an experiment is designed to verify the effectiveness and feasibility of the proposed method. By comparing a single strategy to multiple strategies in an example, it is shown that the total sales profit of chemical products can be increased by around 25% through the simultaneous use of multiple strategies. This illustrates the superiority of combinatorial multiple strategies. Furthermore, the effects of the model parameters on profit are discussed to help manufacturers organize their waste recycling network.

Health problems of industrial applications of radioisotopes

International Nuclear Information System (INIS)

Kudrna, J.

1976-01-01

Radiation hygiene problems of industrial radioisotope applications are discussed. The observance of regulations is emphasised. Radiation protection is based on the principle of preventing early radiation damage and limiting late radiation damage to an acceptable level. The basic requirement is that the cumulated dose should be as low as possible, i.e., as low as is practically feasible in considering economic and social aspects. Notices 59/72 and 65/72, Collection of Laws, rule that if the limit of 3/10 of the maximum permissible dose is likely to be reached, control zones should be defined and marked at places of work where radioisotopes are handled. The characteristics of such a control zone are listed and the measures to be taken in case of accident are outlined. (B.S.)

Hazard visibility and occupational health problem solving the case of the uranium industry

Pearson, J.

1980-01-01

Recent evidence from European research challenges the adequacy of current US exposure guidelines for underground mine radiation. This study traces the history of government regulatory agency and industry response to the hazard of excessive mine radiation in the uranium industry in Colorado some 30 years ago. Problem-solving activity by government agencies and companies is shown to coincide with how visible the health hazard to uranium miners becomes. Hazard visibility and key problem-solving variables are defined and measured. The article also discusses a number of social factors that affect societal response to evidence of an occupational health hazard. Those factors include the elusiveness of the disease and its symptoms, the social class of the victim, the level of medical and scientific interest in its cause and cure, and the economic costs of the disease

Jastrow, R.; Nierenberg, W.; Seitz, F.

1992-01-01

The spectre of major climate change caused by the greenhouse effect has generated intensive research, heated scientific debate and a concerted international effort to draft agreements for the reduction of greenhouse gas emissions. This report of Scientific Perspectives on the greenhouse problem explains the technical issues in the debate in language readily understandable to the non-specialist. The inherent complexities of attempts to simulate the earth's climate are explained, particularly with regard to the effects of clouds and the circulation of the oceans, which together represent the largest factors of uncertainty in current global warming forecasts. Results of the search for the 'greenhouse signal' in existing climate records aredescribed in chapter 3 (part two). Chapter 5 (part two) develops a projection of 21st-century warming based on relatively firm evidence of the earth's actual response to known increases in greenhouse gas emissions during the last 100 years

Neo-industrialization of Kuzbass economy in innovative development of coal industry and machinery

Directory of Open Access Journals (Sweden)

Balabanova Anna

2017-01-01

Full Text Available As part of rental-resource model and access restrictions to capital and new technologies, the attempts to encourage import substitution made by the government do not generate innovative type of economic development and reconstruction of economy’s manufacturing industry competitive on the domestic market. In conditions of searching for a new model of Russian economy development the analysis of a number of problems such as industry degradation, reducing the competitiveness of Russian producers, the growth of structural imbalances and overcoming the negative macroeconomic trends becomes strategically important. This raises the value of neo-industrialization as the integrator of resource security, scientific and industrial potential of Russian economy and high capacity of the domestic market in the innovative development system. A special role neo-industrialization plays for the economic development of old industrial regions, which include Kuzbass (Western Siberia, Russia. Neo-industrial development of Kuzbass economy should be initiated by the technological modernization of mining machinery and innovative development of coal industry.

The current breeding programme on industrial crops in Indonesia

International Nuclear Information System (INIS)

Hamid, Auzay; Abdullah, N.

1982-01-01

There are two main constraints why breeding programme of most industrial crops can not be carried out smoothly. Firstly, most of the industrial crops belong to a perennial group with a relatively long life circle. Secondly, a greater part of them have a very limited genetic diversities in the nature. The low yield capacity per hectare of some crops are mainly due to certain diseases caused by fungi, bacteria, viruses and nematodes, besides several kinds of pests. Efforts have been done to overcome these problems, particularly through improvements of cultural practices, as well as plant breeding, however, major parts of those problems are not solved yet. This paper reviews several problems of industrial crops of economic importance in connection with several aspects of breeding works done in the past and recently faced by ICRI and farmers. It seems that nuclear techniques as a new means in breeding programmes is badly needed, especially to certain crops with a narrow spectrum of genetic diversities with special reference to seek for plants which are expected to be resistant to major diseases and pests.

At present, 72 power reactors are in the condition of being able to operate in U.S., and the total installation capacity has reached 55 million kW, which is equivalent to about 9.5% of the total power generation capacity in U.S. The nuclear power stations produced 12.5% of the total electricity consumption in 1978. Especially in the north eastern part of the U.S., the nuclear power generation occupied 42% of the total power generation at the time of recent peak load, and 47 million barrels of crude oil and 517 million dollars of foreign currency were able to be saved. Moreover, 96 plants amounting to 105 million kW are under construction, and 30 plants of 35 million kW were ordered. Electric power companies, nuclear reactor makers, nuclear fuel and other related industries believe the merits of nuclear power generation and expect that it will flourish if a certain problem is solved. Especially serious problem to which the U.S. nuclear industry is facing now is the problem of uncertainty. Many orders of nuclear power plants have been canceled, and the constructions have been postponed. The capability of the U.S. nuclear industry to construct more than the required facilities, and its extent and the necessary conditions have been investigated by the Atomic Industrial Forum. The important national and international problems of atomic energy are discussed. (Kako, I.)

Hybrid environment for software sensors design applied to the petrochemical industry problems; Ambiente hibrido para a concepcao de sensores de software aplicados aos problemas da industria petroquimica

This article will show a hybrid environment for the conception of software sensors in Foundation Fieldbus (FF) industrial network. These sensors are focused on the measurement and control problems in the petroleum industry, more specifically in oil and gas refining, contributing for the efficiency increase and operation costs decrease of a refining process. The software sensors are based on intelligent algorithms, as neural networks, fuzzy logic and genetic algorithms. These algorithms need input data, in this case the historical variables data associated to industrial petrochemical plant. One option allowed by the environment is the data acquisition from a simulated process by the FF network. Then, the environment presents a hybrid feature, since it is composed by a real (the industrial network) and a simulated (the process) part, with the use of real control and measurements signals. The environment is flexible, allowing typical dynamics of industrial process reproduction without necessity of the physical network amendment and enabling the creation of several situations from a real industrial environment.

Transportation can affect equine health and is a potential source of economic loss to the industry. To identify journey (duration, vehicle, commercial or noncommercial) and horse (sex, age, breed, use, amateur or professional status) characteristics associated with the development of transport-related health problems in horses. Cross-sectional online survey. An online survey was conducted targeting amateur and professional participants in the Australian equine industry; eligible respondents were required to organise horse movements at least monthly. Respondents provided details of the last case of a transport-related health problem that had affected their horse(s). Associations between type of health problem, journey and horse characteristics were examined with multivariable multinomial regression analysis. Based on 214 responses, health problems were classified as injuries, muscular problems, heat stroke, gastrointestinal and respiratory problems, and death or euthanasia. Respiratory problems were reported most frequently (33.7%), followed by gastrointestinal problems (23.8%) and traumatic injuries (16.3%). The type of health problem was associated with journey duration (Pproblems, and death or euthanasia) were more likely to occur on long journeys. Using Standardbreds as the reference group, Thoroughbreds, Arabians and Warmbloods were more likely to experience a severe illness than an injury. Self-selected participation in the study and the self-reported nature of transport-related problems. Horses undertaking journeys of longer than 24 h are at greater risk for the development of severe disease or death. Further studies on long-haul transportation effects are required to safeguard the welfare of horses moved over long distances. © 2016 EVJ Ltd.

Some problems in mechanics of growing solids with applications to AM technologies

Science.gov (United States)

Manzhirov, A. V.

2018-04-01

Additive Manufacturing (AM) technologies are an exciting area of the modern industrial revolution and have applications in engineering, medicine, electronics, aerospace industry, etc. AM enables cost-effective production of customized geometry and parts by direct fabrication from 3D data and mathematical models. Despite much progress in AM technologies, problems of mechanical analysis for AM fabricated parts yet remain to be solved. This paper deals with three main mechanical problems: the onset of residual stresses, which occur in the AM process and can lead to failure of the parts, the distortion of the final shape of AM fabricated parts, and the development of technological solutions aimed at improving existing AM technologies and creating new ones. An approach proposed deals with the construction of adequate analytical model and effective methods for the simulation of AM processes for fabricated solid parts.

Mandel, H.

1979-01-01

In view of the fact that some 15% of the world's population today claim some 50% of the world primary energy consumption, while 52% of the world population must be satisfied with 13% of the primary energy consumption, and in view also of an increase in world population of, at present, approx. 2% per annum, the question arises how to meet the increasing energy demand in the world without incurring international crises and grave economic setbacks. This attempt to find a problem solution is made in the light of the studies of the Conservation Commission of the World Energy Conference. The late author of this contribution, Professor Heinrich Mandel, who was an energy expert of international renown, always tried to examine the energy problem from a global point of view. In his last survey paper on the subject he once more dealt with the narrow margin available in the sector of energy policy and with the great responsibility of the industrialized nations towards the developing countries.

Some problems of recent 'All Japan' strategy for nuclear power exports. Identification of its problems and a proposal for improvement based on international development strategies of the major three categories of businesses constituting nuclear power industry

International Nuclear Information System (INIS)

Tanabe, Tomoyuki

2011-01-01

In Japan, 'All Japan' strategy for nuclear power exports, which arranges engineering companies and electric utilities to sell nuclear power plants providing engineering, procurement, construction and operation abroad, with governmental support of expanded trade insurance, is strongly promoted today as a part of Japan's national growth strategy. However, 'All Japan' strategy generates some problems because the strategy does not consider difference of business strategies concerning international development of each enterprise. This report identifies problems of 'All Japan' strategy based on environmental scanning of major three categories of businesses, which are big nuclear technology companies, vendors and electric utilities constituting nuclear power industry. And this report proposes the way to improve the strategy as follows to resolve those problems. 1) It is necessary to assess the risk of the project that is to be undertaken by 'All Japan' approach carefully. 2) Governmental support for vendors is also needed because the vendors are source of strength of international development of the nuclear industry in Japan. 3) Where the cooperation among the electric utilities is necessary, imposing the risk burden on the utilities should be avoided. 4) It is necessary for government to take measures about 'Weakness' and 'Threat' that each category of business commonly faces.

The need for simulation in complex industrial systems

Directory of Open Access Journals (Sweden)

Aboura Khalid

2012-10-01

Full Text Available We discuss the concept of simulation and its application in the resolution of problems in complex industrial systems. Most problems of serious scale, be it an inventory problem, a production and distribution problem, a management of resources or process improvement, all real world problems require a mix of generic, data algorithmic and Ad-hoc solutions making the best of available information. We describe two projects in which analytical solutions were applied or contemplated. The first case study uses linear programming in the optimal allocation of advertising resources by a major internet service provider. The second study, in a series of projects, analyses options for the expansion of the production and distribution network of mining products, as part of a sensitive strategic business review. Using the examples, we make the case for the need of simulation in complex industrial problems where analytical solutions may be attempted but where the size and complexity of the problem forces a Monte Carlo approach.

Arbitrary order 2D virtual elements for polygonal meshes: part II, inelastic problem

Science.gov (United States)

Artioli, E.; Beirão da Veiga, L.; Lovadina, C.; Sacco, E.

2017-10-01

The present paper is the second part of a twofold work, whose first part is reported in Artioli et al. (Comput Mech, 2017. doi: 10.1007/s00466-017-1404-5), concerning a newly developed Virtual element method (VEM) for 2D continuum problems. The first part of the work proposed a study for linear elastic problem. The aim of this part is to explore the features of the VEM formulation when material nonlinearity is considered, showing that the accuracy and easiness of implementation discovered in the analysis inherent to the first part of the work are still retained. Three different nonlinear constitutive laws are considered in the VEM formulation. In particular, the generalized viscoelastic model, the classical Mises plasticity with isotropic/kinematic hardening and a shape memory alloy constitutive law are implemented. The versatility with respect to all the considered nonlinear material constitutive laws is demonstrated through several numerical examples, also remarking that the proposed 2D VEM formulation can be straightforwardly implemented as in a standard nonlinear structural finite element method framework.

Nuclear industry pays a particular attention to structures integrity problems: well-aware of the possible catastrophic consequence of a major accident, everything is carried out to minimise the risk of such a situation. From the design, and during all the operating life of the plant, a high level of safety is required and checks by the safety authorities, on the basis of reports made by the operator. These two entities ask for R and D activities to support the improvement of the knowledge of the phenomena already identified (as in the case of the vessel of the PWR) or to bring some element of understanding to situation not considered yet, up to the first incident (as in 1998 with the fatigue problems in the thermal mixing zone, at the origin of the Civaux arrest). Among the CEA teams concerned with these problems, the Laboratory of the Structures Integrity and of Normalisation aims to study the integrity problems in metallic nuclear structures leaning on exceptional experimental means: the RESEDA platform allows the realisation of large-scaled tests on analytical tests (representative of analysed phenomena) to reproduce the industrial situation, linked to various and accurate equipment for the measures and the analyses. Three industrial thematics represent to main part of my research activities at CEA in the fracture mechanics field: - the industrial case of the PWR vessel is related to brittle fracture of the ferritic steels, - the piping components, related to ductile tearing and fracture in the brittle-to-ductile domain, - the high temperature fracture mechanics for the components submitted to very complex loadings.

Beebe, R.R.

1993-01-01

The US mining industry has taken its licks over the years but remains economically viable and able to meet global demands, says R.R. Beebe, a retired executive with Homestake Mining Company in San Francisco. Despite a new-found environmental sensitivity, one of the industry's major problems is its negative public image, Beebe admits. open-quotes Mining's record of environmental insensitivity and demands for low-cost access to public lands has burdened an industry now largely committed to doing business fairly, responsibly, and with minimum environmental disturbance,close quotes he asserts. Another part of its image problem deals with the place of mining in the economic scheme of things. Too many people view mining as a open-quotes sunset industry,close quotes he says, making it difficult for the industry to get a fair hearing on the public stage. open-quotes Even the industry's top executives seem to prefer a low profile, rarely serving in government posts...and almost never seeking public platforms from which to expound their views,close quotes Beebe complains. The size of the US mining industry and the importance of the minerals it supplies to domestic industry make it a significant contributor to the nation's standard of living, Beebe emphasizes. This makes it an industry worth saving

The fuel cycle industry will have to adapt to the production of new fuel and in the same time will have to improve its performance. Innovation will be a key factor of success. Innovation must be driven by the needs of the fuel cycle industry to achieve. The fuel cycle requirement of tomorrow, Innovative processes for mining high grade uranium, Innovative enrichment process, Sorting the pellets at Melox plant, Innovation in action, and Innovative waste management in la Hague are presented. A number of innovative solutions are already implemented and are in action on industrial facilities. As problems are becoming more and more tough to address, international cooperation will be required. The fuel cycle industry, as a part of the nuclear power industry, is committed to seek improvements through performance upgrade and innovation. (Cho. G. S.). 10 refs., 4 figs

Climate change as a three-part ethical problem: a response to Jamieson and Gardiner.

Science.gov (United States)

Kingston, Ewan

2014-12-01

Dale Jamieson has claimed that conventional human-directed ethical concepts are an inadequate means for accurately understanding our duty to respond to climate change. Furthermore, he suggests that a responsibility to respect nature can instead provide the appropriate framework with which to understand such a duty. Stephen Gardiner has responded by claiming that climate change is a clear case of ethical responsibility, but the failure of institutions to respond to it creates a (not unprecedented) political problem. In assessing the debate between Gardiner and Jamieson, I develop an analysis which shows a three-part structure to the problem of climate change, in which the problem Gardiner identifies is only one of three sub-problems of climate change. This analysis highlights difficulties with Jamieson's argument that the duty of respect for nature is necessary for a full understanding of climate ethics, and suggests how a human-directed approach based on the three-part analysis can avoid Jamieson's charge of inadequacy.

CHANNEL CATFISH INDUSTRY IN THE USA AND THE OFF-FLAVOR PROBLEM

Directory of Open Access Journals (Sweden)

Nikola Fijan

2000-03-01

Full Text Available The history, the production technology in channel catfish pond farming industry as well as the statistical data on production, processing and product value during past 15 years are presented. The trend of increasing consumption by the population and the presently low prices of grain and soybeans are conductive to further expansion of production. The steady growth of the industry is stimulated by several factors: innovative efforts by farmers, research at the universities and at government institutions some of which have numerous experimental ponds, cooperative extension service for farmers, modern marketing, activities of catfish farming associations, high quality of products from processing plants and vertical integration. The off-flavor in catfish caused by algal metabolites is a major problem in the industry. Genera of algae producing such metabolites, their accumulation in other fish and occurrence in drinking water reservoirs as well as the current emphasis on preventing the entrance of off-flavor contaminated catfish onto the market were reviewed. The main undesirable algal metyabolites are volatile alcohols geosmin and 2-methylisoborneol (MIB. The need for less expensive and quick methods of identifying major off-flavor compounds was pointed out. Research at the University of Arkansas at Pine Bluff, USA, on control of off-flavor algae in experimental ponds by filter-feeding silver carp (Hypophthalmichthys molitrix Val. and tilapias confined in cages showed this approach to be rather promising.

Improving the energy efficiency of industry is essential for maintaining the viability of domestic manufacturing, especially in a world economy where production is shifting to low-cost, less regulated developing countries. Numerous studies have shown the potential for significant cost-effective energy-savings in U.S. industries, but the realization of this potential is hindered by regulatory, information, workforce, and financial obstacles. This report evaluates seven federal policy options aimed at improving the energy efficiency of industry, grounded in an understanding of industrial decision-making and the barriers to efficiency improvements. Detailed analysis employs the Georgia Institute of Technology's version of the National Energy Modeling System and spreadsheet calculations, generating a series of benefit/cost metrics spanning private and public costs and energy bill savings, as well as air pollution benefits and the social cost of carbon. Two of the policies would address regulatory hurdles (Output-Based Emissions Standards and a federal Energy Portfolio Standard with Combined Heat and Power); three would help to fill information gaps and workforce training needs (the Superior Energy Performance program, Implementation Support Services, and a Small Firm Energy Management program); and two would tackle financial barriers (Tax Lien Financing and Energy-Efficient Industrial Motor Rebates). The social benefit-cost ratios of these policies appear to be highly favorable based on a range of plausible assumptions. Each of the seven policy options has an appropriate federal role, broad applicability across industries, utilizes readily available technologies, and all are administratively feasible.

Omar, R; Knight, V F; Aziz Mohammed, M A

2014-01-01

Work-related ocular injuries and illnesses were among the major causes of job absenteeism. This study was conducted to determine if low vision rehabilitation was provided following work-related ocular problems among industrial workers in a developing country. This was a retrospective analysis of case records. Randomly selected records of all employees from the Social Security Organization (SOCSO) Medical Board for 2004 who suffered from ocular injuries and illnesses were selected. Rates of ocular injuries and illnesses according to age, gender, races, types of injuries, types of industries, visual rehabilitation and types of medical interventions were tabulated and analysed. A total of 26 cases of ocular injuries and illnesses were identified where 46.2% suffered from ocular injuries. The remaining 53.8% had ocular and/or systemic diseases. The 40-49-yearold age group suffered the greatest number of injuries (26.92%). Ocular perforating injuries (66.67%) and ocular contusions (33.33%) were the most common types of ocular injury among industrial workers in Kuala Lumpur. Most injuries occurred among workers in the service industry (50%). Almost 60% of these injured workers did not receive any low vision rehabilitation after medical intervention while 25% were given contact lenses or spectacles as rehabilitation and remaining had surgery. The low vision rehabilitation is still unexplored in the management of ocular injuries and illnesses among industrial workers. Introducing low vision rehabilitation can benefit both workers and employers as it provides care beyond spectacles or contact lens prescriptions.

Full Text Available In this work, operational performance in the green supply chain management (SCM of the Thai auto parts industry was investigated. A green supply chain performance measurement (GSPM model was developed from the combination of various concepts including an SCM logistics scorecard, a supply chain operations reference model, a balance scorecard, and green supply chain management. The GSPM has been designed for use as a self-evaluation tool focusing on five decisive areas, or factors, and 28 sub-factors. A factor analysis was conducted using the survey results of the GSPM in order to identify significant factors that represent the green supply chain operation performance. Grouped as three major factors, namely green procurement, green transportation, and green manufacturing; reverse logistics and eco-design; and reuse and recycle of manufacturing, their significance and impact on the auto parts industry in Thailand were highlighted. Specifically, the factor of green procurement, green transportation, and green manufacturing, as major factor 1, in relation with the factor of reverse logistics and eco-design, as major factor 2, were found to have a strong positive relationship with the asset turnover ratio.

Operational procedures - industry observations and opportunities for improvement

International Nuclear Information System (INIS)

Davey, E.

2003-01-01

The purpose of this paper is to relate some of the commonly encountered problems with operational procedures in the nuclear industry and offer practical suggestions for their elimination. The paper is based on recent consultant experience in assisting industry clients with human performance related design and assessment initiatives. Operational procedures are a key part of an integrated system design. Procedures provide the specified instructions for actions people are to undertake in operating a facility to achieve production and safety goals. While organizations continue to make substantial investments in procedure development and maintenance, problems with procedures continue to occur, as evidenced through operating inefficiencies, errors, and events. The paper reviews the role procedures play in facility operations, comments on current development and maintenance practices, discusses the extent of human performance related problems attributed to procedure deficiencies, reviews commonly encountered problems with design and implementation of procedures, and offers suggestions on how some of these issues might be addressed in the future.

This paper examines 3 major health-related issues: 1) existing health problems and illnesses resulting from physical environmental conditions at workplaces; 2) female workers' perception on illness and health protection; and 3) the relationship between illness and risk factors. The study area is textile factories in Bangkok and its peripheries. Data are drawn from the 1987 Survey of Occupational Health and Textile Industrial Development in Thailand: Effect on Health and Socioeconomics of Female Migrant Workers. This study shows that about 20% of female workers have ill-health problems and illness after a period of working mainly due to high levels of dust and noise, and inadequate light. These conditions are hazardous to the respiratory system (resulting in cough and chest tightness), the hearing system (pains as well as impaired and hearing loss), eye systems (irritation, reduced visual capacity) and skin allergy. Such illnesses are intensified in the long- run. The analysis of variances reveals that education, section of work, perception (particularly mask and ear plug) significantly affect these illnesses. This study concludes that health education and occupational health should be provided in factories with emphasis on health prevention and promotion.

Mazur, J

1993-09-01

When you realize how long the problem of child labor has been around, anyone who ventures into the terrain of remedies obviously needs a long memory and not a little optimism. What have we tried? What has worked? And what has not worked? To answer these questions, we must first look at how we have diagnosed the problem. Some say that the return of child labor is due to the present recession. Hard-pressed businesses are looking for cheap and cheaper labor. Sweatshops proliferate. When the recession recedes, so will child labor. If it were that simple, we could all congratulate ourselves on having conducted this enlightened symposium and go home without worrying much more about the problem. The magic hand of the market, in due course, will straighten it all out. Let me tell you something about the apparel industry in New York where new laws and strict enforcement make the only difference. Over 80% of OSHA inspections were triggered by the state's Apparel Task Force.

Parts Quality Management: Direct Part Marking of Data Matrix Symbol for Mission Assurance

Science.gov (United States)

Moss, Chantrice; Chakrabarti, Suman; Scott, David W.

2013-01-01

A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using direct part marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, Low Earth Orbit), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (label printing, data plates, and direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including inhouse vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

Industrial ecology: a new perspective on the future of the industrial system.

Science.gov (United States)

Erkman, S

2001-09-22

Industrial ecology? A surprising, intriguing expression that immediately draws our attention. The spontaneous reaction is that "industrial ecology" is a contradiction in terms, something of an oxymoron, like "obscure clarity" or "burning ice". Why this reflex? Probably because we are accustomed to considering the industrial system as isolated from the Biosphere, with factories and cities on one side and nature on the other, as well as the recurrent problem of trying to minimise th impact of the industrial system on what is "beyond" it: its surroundings, the "environment". As early as the 1950's, this end-of-pipe angle was the one adopted by ecologists, whose first serious studies focused on the consequences of the various forms of pollution on nature. In this perspective on the industrial system, human industrial activity as such remained outside the field of research. Industrial ecology explores the opposite assumption: The industrial system can be seen as a certain kind of ecosystem. After all, the industrial system, just as natural ecosystems, can be described as a particular distribution of materials, energy, and information flows. Furthermore, the entire industrial system relies on resources and services provided by the Biosphere, from which it cannot be dissociated. (It should be specified that "industrial", in the context of industrial ecology, refers to all human activities occurring within modern technological society. Thus, tourism, housing, medical services, transportation, agriculture, etc. are part of the industrial system.) Besides its rigorous scientific conceptual framework (scientific ecology), industrial ecology can also be seen as a practical approach to sustainability. It is an attempt to address the question, "How can the concept of sustainable development be made operational in an economically feasible way?" Industrial ecology represents precisely one of the paths that could provide concrete solutions. Governments have traditionally approached

Full Text Available Recently, the long term development in Indonesia has changed agricultural sector to the industrial sector. This development can apparently harm our own people. This is due to the waste that is produced from factories. The waste from various factories seems to have different characteristics. This defference encourages us to be able to find out different of methods of managing waste so that cost can be reduced, especially in water treatment. In order that industrial development and environmental preservation can run together in balance, many institutions involved should be consider, especially in the industrial chain, the environment, and human resource, these three elements can be examined in terms of their tolerance to waste.

This study explores the impact of adolescent part-time work experience on problem behaviors in the South Korean context. To achieve this, propensity score matching (PSM) analyses were employed based on data from the Korean Education Employment Panel (KEEP). Results indicate that adolescents' part-time employment during their secondary school years had significantly undesirable effects on drinking and smoking, even after preexisting differences between the two groups (i.e., those adolescents who participated in part-time work and those who did not) were controlled by PSM. However, an insignificant difference was detected in the likelihood of running away from home. Implications of the results are discussed in terms of changes in the meanings of adolescence and of participating in part-time work in South Korea. © 2016 The Authors.

'California Dreaming' of the Power Industry Reform

Energy Technology Data Exchange (ETDEWEB)

Chang, Hyun Jun [Korea Energy Economics Institute, Euiwang (Korea)

2001-03-01

California power crisis confirms a necessity of reforming the power industry. Korea also has many problems that have produced California crisis. The problems are the market distortion from the price regulation, the difficulties in establishing power plants due to NIMBY, and the uncertainty of investment value caused by political logic prior to economic logic. It is a part of the political logic to ask our attention that the Governor of California, Davis, concludes the deregulation of the power industry with 'the perfect failure' and leaves its responsibility to the market. The heart of the problems is a loophole of the deregulation procedure that the Government tries a political compromise ignoring the market principle, not the market itself. It is the most earnest lesson to our situation where a political power is prior to the market.

2015-06-01

Full Text Available This paper concerns important and difficult problems connected with a design and construction of thermonuclear reactors, which have to use nuclear fusion reactions of heavy isotopes of hydrogen, i.e., deuterium (D and tritium (T. There are described conditions in which such reactions can occur, and different methods of a high-temperature plasma generation, i.e., high-current electrical discharges, intense microwave pulses, and injection of energetic neutral atoms (NBI. There are also presented experimental facilities which can contain hot plasma for an appropriate period, and particularly so-called tokamaks. The second part presents the technical problems which must be solved in order to build a thermonuclear reactor, that might be used for energetic purposes. There are considered problems connected with a choice of constructional materials for a vacuum chamber, its internal parts, external windings generating a magnetic field, and necessary shields. The next part considers the handling of radioactive tritium; the using of alpha particles (4He for additional heating of plasma; recuperation of hydrogen isotopes absorbed in the tokamak internal parts, and a removal of a helium excess. There is presented a scheme of a future thermonuclear power plant and critical comments on a road map which should enable the construction of an industrial thermonuclear reactor (DEMO.

Identification and quantification of principal–agent problems affecting energy efficiency investments and use decisions in the trucking industry

International Nuclear Information System (INIS)

Vernon, David; Meier, Alan

2012-01-01

Energy related Principal–Agent (PA) problems cause inefficient combinations of investment, operating costs, and usage behavior. The complex market structure of the trucking industry contributes to split incentives because entities responsible for investments in energy efficiency do not always pay fuel costs and drivers are often not rewarded for fuel-efficient operation. Some contractual relationships exist in the trucking industry that hinder responses to fuel price signals. Up to 91% of total trucking fuel consumption in the U.S. is affected by “usage” PA problems, where the driver does not pay fuel costs and lacks incentive for fuel saving operation. Approximately 23% of trailers are exposed to an “efficiency problem” when owners of rented trailers do not pay fuel costs and therefore have little incentive to invest in efficiency upgrades such as improved trailer aerodynamics and reduced tire rolling resistance. This study shows that PA problems have the potential to significantly increase fuel consumption through avoided investments, insufficient maintenance, and fuel-wasting practices. Further research into the causes and effects of PA problems can shape policies to promote better alignment of costs and benefits, leading to reduced fuel use and carbon emissions. - Highlights: ► We identify and quantify principal agent market failures in the trucking industry. ► Up to 91% of truck fuel consumption is exposed to a usage principal–agent market failure. ► Twenty-three percent of trailers are exposed to an efficiency principal–agent market failure. ► These market failures at least partially insulate key decision makers from fuel price signals.

Parts Quality Management: Direct Part Marking via Data Matrix Symbols for Mission Assurance

A United States Government Accountability Office (GAO) review of twelve NASA programs found widespread parts quality problems contributing to significant cost overruns, schedule delays, and reduced system reliability. Direct part-marking with Data Matrix symbols could significantly improve the quality of inventory control and parts lifecycle management. This paper examines the feasibility of using 15 marking technologies for use in future NASA programs. A structural analysis is based on marked material type, operational environment (e.g., ground, suborbital, orbital), durability of marks, ease of operation, reliability, and affordability. A cost-benefits analysis considers marking technology (data plates, label printing, direct part marking) and marking types (two-dimensional machine-readable, human-readable). Previous NASA parts marking efforts and historical cost data are accounted for, including in-house vs. outsourced marking. Some marking methods are still under development. While this paper focuses on NASA programs, results may be applicable to a variety of industrial environments.

Global warming and the insurance industry

Science.gov (United States)

Berz, G. A.

1992-06-01

In the last few decades, the international insurance industry has been confronted with a drastic increase in the scope and frequency of great natural disasters. The trend is primarily attributable to the continuing steady growth of the world population and the increasing concentration of people and economic values in urban areas. An additional factor is the global migration of populations and industries into areas like the coastal regions which are particularly exposed to natural hazards. The natural hazards themselves, on the other hand, have not yet shown any significant increase. In addition to the problems the insurance industry has with regard to pricing, capacity and loss reserves, the assessment of insured liabilities, preventive planning and the proper adjustment of catastrophe losses are gaining importance. The present problems will be dramatically aggravated if the greenhouse predictions come true. The increased intensity of all convective processes in the atmosphere will force up the frequency and severity of tropical cyclones, tornados, hailstorms, floods and storm surges in many parts of the world with serious consequences for all types of property insurance. Rates will have to be raised and in certain coastal areas insurance coverage will only be available after considerable restrictions have been imposed, e.g., significant deductibles and/or liability or loss limits. In areas of high insurance density the loss potential of individual catastrophes can reach a level where the national and international insurance industries run into serious capacity problems. Recent disasters showed the disproportionately high participation of reinsurers in extreme disaster losses and the need for more risk transparency if the insurance industry is to fulfill its obligations in an increasingly hostile environment.

ND/FE magnets: Industrial and economical problems in the short and long term

International Nuclear Information System (INIS)

Falconnet, P.

1985-01-01

The Rare Earths (RE) world is a small and closed world that needs better communication with the outside and specially with new potential users. The availability of neodymium today is very linked to the existing applications like glass and capacitors. Though no short or long term scarcity can be foreseen, the Rare Earths Industry has to produce increasing amounts of various neodymium compounds and may have to invest in some finishing capacity before knowing which Nd compounds will be used by metal or magnet makers in some years. Despite the high energy product of Nd/Fe magnets some properties like Curie temperature need to be improved to find a large use. Similarly the production cost of these magnets is today rather high, and it will take some years to take advantage of large production scale. The industrial and economical problems of Nd/Fe magnets are discussed in this paper

A capacitated vehicle routing problem with order available time in e-commerce industry

Science.gov (United States)

Liu, Ling; Li, Kunpeng; Liu, Zhixue

2017-03-01

In this article, a variant of the well-known capacitated vehicle routing problem (CVRP) called the capacitated vehicle routing problem with order available time (CVRPOAT) is considered, which is observed in the operations of the current e-commerce industry. In this problem, the orders are not available for delivery at the beginning of the planning period. CVRPOAT takes all the assumptions of CVRP, except the order available time, which is determined by the precedent order picking and packing stage in the warehouse of the online grocer. The objective is to minimize the sum of vehicle completion times. An efficient tabu search algorithm is presented to tackle the problem. Moreover, a Lagrangian relaxation algorithm is developed to obtain the lower bounds of reasonably sized problems. Based on the test instances derived from benchmark data, the proposed tabu search algorithm is compared with a published related genetic algorithm, as well as the derived lower bounds. Also, the tabu search algorithm is compared with the current operation strategy of the online grocer. Computational results indicate that the gap between the lower bounds and the results of the tabu search algorithm is small and the tabu search algorithm is superior to the genetic algorithm. Moreover, the CVRPOAT formulation together with the tabu search algorithm performs much better than the current operation strategy of the online grocer.

The problem of saturation in the natural gas distribution pipelines in Brazil is not urgent, but it's possible to notice the need of reinforcements in some extensions. Price regulation does not consider this problem yet, but it's already predicted the adoption of a three-part tariff considering a contracted capacity for some industrial consumers - industries that buy more than 500.000 m3/month in the COMGAS distribution area. Some industries, like potteries and glass makers, would probably not suffer strong impacts with the implementation of this three-part tariff, since the majority of their manufacturing processes are continuous. Others sectors would probably have negative impacts with the contracted capacity, like pulp and paper, metallurgy and textile industries. The way that industry will manage the contracted capacity is still unknown. Some possibilities are: considering natural gas as one of the variables in the productions' decision; having a 'Back-up' system when the consumption surpass the contracted capacity; switch fuels when total consumption is above 500.000 m{sup 3}/month, so that the company does not fit in the three-part tariff. The three-part tariff has not been published yet, but it's already necessary a sign to the market that this will occur in the near future, so that the companies involved can already create a strategy for the use of natural gas. This signal is already predicted in the Technical Paper number X of CSPE. (author)

Significance of material analysis in industry

International Nuclear Information System (INIS)

Bourke, T.M.

1999-01-01

Full text: Most industries need to have laboratories to meet production, customer and statutory requirements. Failure to have such a service would result in production losses, material failures and customer complaints leading to expensive claims for damages. Laboratory functions are to monitor production processes, certify the end product and assist in trouble shooting production problems and material failures. This means that laboratories are an essential part of industry and need to have access to a wide range of instrumentation (XRF, XRD, AES, ICP, SEM, etc). Monitoring and reporting on the industries environmental licences for effluent and emissions is also the responsibility of the laboratory. Licence exceedance leads to heavy fines and continual exceedance would result in plant closure. The mining industry relies heavily on laboratories to certify that the material meets the customer specification. The large tonnages involved means that small errors in composition can result in losses amounting to many thousands of dollars. Copyright (1999) Australian X-ray Analytical Association Inc

1994-01-01

As part of an NSOF programme, GNS has developed a small capability for Ion Beam Analysis of polymers, and has investigated the possibilities applying these analytic tools to polymer problems in New Zealand. In the first part of the report, the basis of the IBA method is described, together with experimental measurements of polymer mixing made with the 3 MV KN Van de Graaff accelerator of the Institute. In the second part, reports on a series of visits to industrial plants and other organisations involved in plastics manufacturing and recycling are given. Finally, we draw the conclusion that Ion Beam Analysis should play an important role in future polymer research in New Zealand, but that Industry funding for such research seems unlikely at present. In the meantime, it is proposed that GNS should make a strategic investment by maintaining a small polymer project as a framework within which to maintain contact with New Zealand's polymer research community.

Problems of placement of industrial wastes in landfills in the industrial city

Directory of Open Access Journals (Sweden)

STEPANOV Evgeniy Georgievich,

2017-04-01

Full Text Available The article shows that the anthropogenic transformation of the environment increases when production wastes and consumption are placed in landfills. Hygienic condition of the areas with high population density and developed industry is determined by the increased amount of household and industrial waste, mainly deposited in the numerous landfills. This situation is studied on the example of landfills used for industrial wastes produced by the enterprises JSC «Gazprom Neftekhim Salavat», JSC «Salavatsteklo», located in the city of Salavat of the Republic of Bashkortostan. The sources of industrial pollution in Salavat have been analyzed. One should note that the city-forming enterprise is the JSC «Gazprom Neftekhim Salavat» which share of the total amount of wastes generated in the city per year is 80%. Another company which contributes significantly to this process is the JSC «Salavatsteklo». To study the possible migration of contaminants to the aquifer an observation well has been made at the landfill site. The research of the water obtained from the observation well at the polygon identified maximum allowable concentrations for chemical oxygen demand (COD, phenol and oil products. The groundwater occurrence modes have been studied. The migration of the chemicals contained in the body of the landfill, to groundwater, has been revealed. That leads to contamination of surface water. Laboratory studies of water objects in the zone of influence of industrial waste landfill in Romodanovskomu career have been performed. It was determined that excess of maximum permissible concentration of benzene, and the presence of toluene, lead, phenol indicates the pollution of groundwater by substances stored in landfills Romanovskogo career, both by infiltration and subsequent migration to groundwater of adjacent aquifers and through surface runoff and infiltration from snowmelt and rainwater.

Examples from nuclear waste handling and the accident at Three Mile Island demonstrate that the spectrum of communications is broad, complex, and fascinating. Generally, people use best that part of the spectrum that is essential to their normal endeavors and in which they have been trained. It is unfortunate for those in the nuclear industry that little in their backgrounds or training has equipped them to cope with the political debate in which they are embroiled. They do, however, have problem-solving disciplines that would serve them well in this situation if only they were used to define the problem and plan the remedies without compromising either truth or integrity. 13 figures

Since the electric industry has grappled with a prevention of the environmental pollution such as the air pollution and water contamination as a forerunner in case of construction and operation of the power facilities, and at the same time has conducted actively the environmental conservation countermeasures, it has consequently achieved the environmental conservation level as a top level in the world. On the other hand, as for the emission quantity of CO2 relating to the earth warming, the power field occupies about one fourth of total Japan. Therefore the electric industry should aim at the electric energy supply considering the influence on the environment, such as the power supply structure to restrain CO2 emission as less as possible, higher efficiency of equipments, higher efficiency of energy utilization by using the unused energy and so forth. In addition to it, the consumer side should aim at the social structure with a recycle type such as saving resources and saving energy, and aim at changeover of life style. It is hoped to conduct the overall measure including the items mentioned above. In this report, the recent trend of earth enviromental problems, grappling with the environmental problems as a forerunner such as the prevention measure of air pollution in the thermal power plant, etc., and the correspondence to the earth warming problems are outlined. 11 refs., 9 figs., 3 tabs.

1978-01-01

With the development of nuclear energy the present-day problems of radioprotection are studied in the light of new radiobiological knowledge. The following points are analysed in turn: radioprotection norms, the notion of acceptable risk; influence of dose rate and fractionation; the low-dose problem; relative biological effectiveness (RBE) and quality factor (Q.F.); the biological problem of long-term effects. The genetic risk due to accepted radioprotection norms is estimated. The part played by radioprotection organisations is underlined, with emphasis on the fact that radioactivity is the most strictly and effectively regulated of all industrial inconveniences. It is pointed out that medical irradiation is not subject to the legislations and regulations listed [fr

Inverse scattering problems with multi-frequencies

International Nuclear Information System (INIS)

Bao, Gang; Li, Peijun; Lin, Junshan; Triki, Faouzi

2015-01-01

This paper is concerned with computational approaches and mathematical analysis for solving inverse scattering problems in the frequency domain. The problems arise in a diverse set of scientific areas with significant industrial, medical, and military applications. In addition to nonlinearity, there are two common difficulties associated with the inverse problems: ill-posedness and limited resolution (diffraction limit). Due to the diffraction limit, for a given frequency, only a low spatial frequency part of the desired parameter can be observed from measurements in the far field. The main idea developed here is that if the reconstruction is restricted to only the observable part, then the inversion will become stable. The challenging task is how to design stable numerical methods for solving these inverse scattering problems inspired by the diffraction limit. Recently, novel recursive linearization based algorithms have been presented in an attempt to answer the above question. These methods require multi-frequency scattering data and proceed via a continuation procedure with respect to the frequency from low to high. The objective of this paper is to give a brief review of these methods, their error estimates, and the related mathematical analysis. More attention is paid to the inverse medium and inverse source problems. Numerical experiments are included to illustrate the effectiveness of these methods. (topical review)

Behaviorism: part of the problem or part of the solution.

Science.gov (United States)

Holland, J G

1978-01-01

The form frequently taken by behavior-modification programs is analyzed in terms of the parent science, Behaviorism. Whereas Behaviorism assumes that behavior is the result of contingencies, and that lasting behavior change involves changing the contingencies that give rise to and support the behavior, most behavior-modification programs merely arrange special contingencies in a special environment to eliminate the "problem" behavior. Even when the problem behavior is as widespread as alcoholism and crime, behavior modifiers focus on "fixing" the alcoholic and the criminal, not on changing the societal contingencies that prevail outside the therapeutic environment and continue to produce alcoholics and criminals. The contingencies that shape this method of dealing with behavioral problems are also analyzed, and this analysis leads to a criticism of the current social structure as a behavior control system. Although applied behaviorists have frequently focused on fixing individuals, the science of Behaviorism provides the means to analyze the structures, the system, and the forms of societal control that produce the "problems".

Full Text Available The challenging EU targets for reducing greenhouse gas emissions and generating electricity from renewable sources were established as – 20% and 20% by 2020. As part of the strategy, EU confirmed in 2007 the need to save around 300 million tonnes of CO₂ per year from EU buildings by 2020. Housing itself accounts for some 40% of emissions, mostly associated with heating. Industry will be expected to source and use appropriate materials and process technologies to improve their own energy consumption and at the same time deliver products that permit to reach those targets. This article examines the relationship between the emissions from relevant sectors of the glass industry and compares them with the carbon savings that can be achieved with the products the industry makes. Four main areas are discussed: glass fibre insulation, advanced glazing (low emissivity glass and advanced solar glass, continuous filament glass fibre and special glass applications. It is suggested that as well as considering the use of free allowances or border carbon adjustment, member states need to take account of the benefit of these products when formulating emission constraint policies; a carbon credit feedback loop should be also explored to encourage cheaper production and installation and avoid carbon leakage.

La UE ha establecido los objetivos de reducción de emisiones de CO₂ en -20% y de generación de electricidad a partir de energías renovables en el 20% para el año 2020. Como parte de esta estrategia la UE confirmó en 2007 la necesidad de reducir en 300 millones de toneladas por año las emisiones provenientes de los edificios en el mismo año 2020. El parque de viviendas aporta alrededor del 40% de las emisiones, básicamente relacionadas con sistemas de calefacción. Se espera de la industria que utilice procesos apropiados para mejorar su propio consumo energético y al mismo tiempo desarrolle y produzca materiales que

Radiotracer Generators for Industrial Applications

International Nuclear Information System (INIS)

2013-01-01

Radiotracers have been widely used throughout industry to optimize processes, solve problems, improve product quality, save energy and reduce pollution. Their technical, economic and environmental benefits have been recognized by both the industrial and the environmental sectors. The most important radiotracer techniques have been transferred to many developing Member States through IAEA Technical Cooperation projects. However, in spite of their manifest benefits, radiotracer techniques continue to be underutilized, not only by developing countries but also by more industrialized nations. There are a number of factors that restrict the usage of the radioisotope techniques, but chief among them is the timely availability of suitable radiotracers. Ensuring timely availability of suitable radionuclides is a main hurdle to the use of radiotracer techniques in industry. For developing countries that do not possess radioisotope production facilities, the long time required for import of radionuclides not only completely rules out the use of short half-life nuclides, but also makes it impossible for the radioisotope applications teams to respond to problems of an urgent nature. Many possible radiotracer investigations are not being carried out in developing countries because of this problem. Even in industrialized countries, radionuclide supply is often a problem, as many of the former suppliers of industrial radionuclides have switched their production facilities to serve the more lucrative radiopharmaceuticals market. Obtaining continuity of supply of radionuclides with which to carry out extended studies in difficult-to-access locations, such as offshore oil platforms, is also a significant challenge. Making use of tracers from radionuclide generators can alleviate the difficulties associated with radioisotope supply. Two commercially available medical radionuclide generators, 99 Mo/ 99 mTc and 113 Sn/ 113 mIn, have been used for this purpose, but their use has been

Why finding costs are now a major problem [in the US petroleum industry

International Nuclear Information System (INIS)

Gaddis, D.; Brock, H.; Boynton, C.

1993-01-01

A major problem facing the US petroleum industry is the higher average finding costs that now exist within the US compared to the average finding costs outside the US. It has been argued that federal lands and offshore areas need to be open for drilling in order to reduce average finding costs in the US. Certainly, the development of a national energy policy must acknowledge the importance of finding costs. Financial analysts for some time have acknowledged the importance of finding costs in evaluating individual energy firms. Analysts expect mergers when it is cheaper for companies to purchase reserves than to find them. Just as industry-average finding costs are a key determinant of long-term market prices for oil and gas, relative finding costs are a key determinant of a company's stock market value. Division managers are now judged regularly by top management on the basis of relative finding costs. The heavy use of finding costs data is causing its own problems, however, because there is as yet no standard for calculating and reporting those costs. This article analyzes the strengths and weaknesses of conventional techniques for determining finding costs. Our goal is a finding costs measure that is a reliable indicator of future profitability. Conceptually, a finding cost figure is a measurement of how much it costs a company to find a barrel of oil or an mcf of gas. The figure is arrived at by dividing the figure for costs incurred during a specified period by the volume (barrels or mcfs) of reserve added during the same period. (author)

Depression and Behavioral Problems Among Adolescent Girls and Young Women Employees of the Textile Industry in India.

2018-01-01

Stress and depression are common in textile industry employees due to inadequate working conditions and challenging socioeconomic conditions. The objective of the study was to assess depression and mental health among adolescent and young females currently employed in a textile factory located in Tamil Nadu compared with past employees and women who have never been employed. This cross-sectional study included a total of 107 participants in each study group who were interviewed. The Patient Health Questionnaire-9 and Strengths and Difficulties Questionnaire were administered to screen participants for depression and mental health. More current employees (16.82%) and past employees (15.88%) suffered from depression severe enough to require treatment compared with never employed girls and young women (2.8%). Of the study participants, 59.8% of current employees, 63.6% of past employees, and 32.7% of never employed women had mental health or behavior problems. In the regression model, history of abuse was significantly associated with depression. Participants who were current employees and reported family debt and a history of abuse were significantly more likely to have mental health or behavior problems. Mental health issues such as depression and behavior problems were more likely among adolescent girls currently employed in textile industries. Further studies into the causes of this phenomenon are needed.

Modelling of an industrial environment, part 2.: External dose calculation with relevant countermeasures

International Nuclear Information System (INIS)

Eged, K.; Kis, Z.; Alvarez-Farizo, B.; Gil, J.; Voigt, G.

2002-01-01

The calculation of the collective dose and averted collective dose after applying countermeasures in an industrial environment has been divided in two parts. In the first part (Kis et al. 2002) separate Monte Carlo simulations of photon transport resulted in the air kermas per photon per unit area due to the industrial surfaces contaminated by 1 37C s at specific points using the so-called local approach. In the local approach the air kerma rates due to specific intervention elements at the evaluation locations in the whole environment are determined (Gutierrez et al. 2000). In this way the collective and averted collective dose due to the radiation from a particular intervention element (e.g. the roof of a building) can be obtained. It can, therefore, provide a ranking of the specific intervention elements based on their contribution to collective dose as well. The deposition pattern and the long-term behaviour of deposited radionuclides vary widely in natural circumstances; therefore the number of the photons emitted from the various surfaces per unit area and time can differ significantly. This means the results of the Monte Carlo simulations have to be weighted according to the number of emitted photons so that the actual radiation field can be set up. For this purpose, a dose calculation code has been developed in the framework of the TEMAS project (Gutierrez et al. 2000) which allows to calculate collective doses for different environments. This code has been applied in the present work

Efficient Parallel Sorting for Migrating Birds Optimization When Solving Machine-Part Cell Formation Problems

Directory of Open Access Journals (Sweden)

Ricardo Soto

2016-01-01

Full Text Available The Machine-Part Cell Formation Problem (MPCFP is a NP-Hard optimization problem that consists in grouping machines and parts in a set of cells, so that each cell can operate independently and the intercell movements are minimized. This problem has largely been tackled in the literature by using different techniques ranging from classic methods such as linear programming to more modern nature-inspired metaheuristics. In this paper, we present an efficient parallel version of the Migrating Birds Optimization metaheuristic for solving the MPCFP. Migrating Birds Optimization is a population metaheuristic based on the V-Flight formation of the migrating birds, which is proven to be an effective formation in energy saving. This approach is enhanced by the smart incorporation of parallel procedures that notably improve performance of the several sorting processes performed by the metaheuristic. We perform computational experiments on 1080 benchmarks resulting from the combination of 90 well-known MPCFP instances with 12 sorting configurations with and without threads. We illustrate promising results where the proposal is able to reach the global optimum in all instances, while the solving time with respect to a nonparallel approach is notably reduced.

Sleepiness and alertness in American industries

Coleman, R.M.; Dillingham, J.; Dement, W.C.

1989-01-01

Recent evidence that industrial accidents may be caused in part by shiftworkers' lack of alertness has caused growing concern at the US Nuclear Regulatory Commission and within the scientific community. The purpose of the study reported in this paper was threefold: (1) Is sleepiness on the job specific to utility plants? (2) Are performance and safety problems caused by sleepiness specific to utility plants? (3) Are specific shift schedules associated with a higher prevalence of sleepiness? Findings indicate sleepiness on the job among shiftworkers is a widespread problem, not limited to the nuclear power industry. The most common solution in American industry is to overstaff each shift and discipline sleeping employees. Results show this is not effective. A more proactive solution is recommended including some of the following: (1) Provide employees education to assist adjustment to shiftwork. (2) Design and implement shift schedules that are more compatible with human physiological capabilities. (3) Allow officially sanctioned napping on shift as is done in Japan. (4) Divide 6-, 8-, or 12-h shifts into smaller blocks of 2 to 3 h of primary duty. (5) make the environment where employees work more conductive to alertness. (6) Develop a firehouse type of schedule where some employees sleep throughout the night, but are awakened if operational problems arise. (7) Provide incentives to employees to adjust their life style to the night shift and reward them with time off

Full Text Available Purpose. Problem of representation lack of scientists’ publications, including transport scientists, in the international scientometric databases is the urgent one for Ukrainian science. To solve the problem one should study the structure and quality of the information flow of scientific periodicals of railway universities in Ukraine and to determine the integration algorithm of scientific publications of Ukrainian scientists into the world scientific information space. Methodology. Applying the methods of scientific analysis, synthesis, analogy, comparison and prediction the author has investigated the problem of scientific knowledge distribution using formal communications. The readiness of Ukrainian railway periodicals to registration procedure in the international scientometric systems was analyzed. The level of representation of articles and authors of Ukrainian railway universities in scientometric database Scopus was studied. Findings. Monitoring of the portals of railway industry universities of Ukraine and the sites of their scientific periodicals and analysis of obtained data prove insufficient readiness of most scientific publications for submission to scientometric database. The ways providing sufficient "visibility" of industry periodicals of Ukrainian universities in the global scientific information space were proposed. Originality. The structure and quality of documentary flow of scientific periodicals in railway transport universities of Ukraine and its reflection in scientometric DB Scopus were first investigated. The basic directions of university activities to integrate the results of transport scientists research into the global scientific digital environment were outlined. It was determined the leading role of university libraries in the integration processes of scientific documentary resources of universities into the global scientific and information communicative space. Practical value. Implementation of the proposed

Despite the considerable potential oil resources in Russia, oil production is currently falling to the extent where, if present trends continue, imports will be necessary in the next few years in order to meet domestic demand. Foreign investment could make an effective contribution to stabilizing the Russian oil industry. The large resource base, favourable production costs, highly skilled workers and the conversion potential of the former defence industries to oil and gas equipment, are considerable attractions for foreign investors. However, for the time being there are many obstacles and uncertainties for oil and gas investment. Among these are political instability, high taxation, export tariffs, the legal environment, bureaucratic difficulties over new project negotiation, and problems related to oil and gas transportation. Current legislative activities which may lead to a better investment environment are described. (UK)

2015-11-01

We investigated how industry claim-makers countered concerns about obesity and other nutrition-related diseases in newspaper coverage from 2000, the year before the US Surgeon General's Call to Action on obesity, through 2012. We found that the food and beverage industry evolved in its response. The defense arguments were made by trade associations, industry-funded nonprofit groups, and individual companies representing the packaged food industry, restaurants, and the nonalcoholic beverage industry. Individual companies used the news primarily to promote voluntary self-regulation, whereas trade associations and industry-supported nonprofit groups directly attacked potential government regulations. There was, however, a shift away from framing obesity as a personal issue toward an overall message that the food and beverage industry wants to be "part of the solution" to the public health crisis.

2008-01-01

The possibilities of effective solutions of relevant technological problems are considered based on the analysis of fundamental physical aspects, elucidation of the micromechanisms and interrelations of aging and hydrogen embrittlement of materials in the hydrogen industry and gas-main industries. The adverse effects these mechanisms and processes have on the service properties and technological lifetime of materials are analyzed. The concomitant fundamental process of formation of carbohydride-like and other nanosegregation structures at dislocations (with the segregation capacity 1 to 1.5 orders of magnitude greater than in the widely used Cottrell 'atmosphere' model) and grain boundaries is discussed, as is the way in which these structures affect technological processes (aging, hydrogen embrittlement, stress corrosion damage, and failure) and the physicomechanical properties of the metallic materials (including the technological lifetimes of pipeline steels).

Industrial developments frequently drive to the natural resources extinction. The recycling era has come out a long time ago and it has been evident that great part of industrial work's problems are related to the pollution and the raw materials extinction. These problems should be solved, with advantages, through industrial residues recycling. This study deals with glass and glass-ceramics materials obtained from oil shale (Irati Formation-Sao Mateus do Sul-Parana State) industrialization residues. The reached results show that a controled devitrification of retorted oil shale glass improves its performance related to chemical attack. The crystallinity caracterization of the oil shales glass-ceramic was made through X-ray diffraction. (author) [pt

Status and Analysis on Effects of Energy Efficiency Standards for Industrial Boilers in China

Energy conservation and environmental protection is the basic policy of China, and is an important part of ecological civilization construction. The industrial boilers in China are featured by large quantity, wide distribution, high energy consumption and heavy environmental pollution, which are key problems faced by energy conservation and environmental protection in China. Meanwhile, industrial boilers are important equipment for national economy and people’s daily life, and energy conservation gets through all segments from type selection, purchase, installation and acceptance to fuel management, operation, maintenance and service. China began to implement such national mandatory standards and regulations for industrial boiler as GB24500-2009 The Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades of Industrial Boilers and TSG G002-2010 Supervision Regulation on Energy-Saving Technology for Boilers since 2009, which obviously promote the development of energy conservation of industrial boilers, but there are also some problems with the rapid development of technologies for energy conservation of industrial boilers. In this paper, the implementation of energy efficiency standards for industrial boilers in China and the significance are analyzed based on survey data, and some suggestions are proposed for the energy efficiency standards for industrial boilers.

Nuclear power proliferation. Problems of international control

Johnson, B [International Inst. for Environment and Development, London (UK)

1977-09-01

The nuclear industry is experiencing a multiple crisis in which economic, technical and ethical aspects are blended inextricably. Nuclear hardware costs have everywhere soared far beyond inflation in the last five years, largely as a result of delays in programme completion arising from problems of reactor and fuel cycle. Meanwhile, partly as a result of this cost escalation, there is widespread and growing doubt as to whether capital will be available to finance the electricity generating levels projected by the industry and by governments for the 1990s. The nuclear industry is now in trouble at every stage of the fuel cycle. The industry's difficulties have also revealed a lack of overall - but particularly nuclear - energy strategy at either national or international levels, and a lack of will to create regulations and institutional machinery at either of these levels which might reassure both concerned publics and the energy industries themselves. This paper appraises some of the present limitations of international institutions in achieving control and management of nuclear power.

Some of the present limitations of international institutions in achieving control and management of nuclear power are reviewed and appraised. The nuclear industry is experiencing a multiple crisis in which economic, technical, and ethical aspects are blended. Nuclear hardware costs have increased faster than inflation in the last five years, largely as a result of delays in program completion arising from reactor and fuel-cycle safety problems. Meanwhile, there is a widespread and growing doubt, partly as a result of this cost escalation, as to whether capital will be available to finance the electricity-generating levels projected by the industry and by governments for the 1990s. The nuclear industry is now in trouble at every stage of the fuel cycle. The industry's difficulties have also revealed a lack of overall--but particularly nuclear--energy strategy at either national or international levels, and a lack of will to create regulations and institutional machinery at either of these levels that could reassure the concerned public and the energy industries.

32 companies belong to the industrial association 'Kernbrennstoffkreislauf e.V.'. They do business in the nuclear fuel cycle in the Federal Republic of Germany. This field comprises the different forms of dealing with nuclear fuels and the materials from which they are made, including the radioactive wastes resulting from the use of nuclear fuels, with the exception of the handling of such materials in nuclear power plants. Some 5000 persons - subcontractors not counted - are employed in this branch of industry. Turnover amounts to about 2 billion Deutsch Marks yearly. But it is a branch of industry that is important beyond the figures mentioned. Its existence constitutes the precondition for building, operating, and exporting nuclear power plants. This paper is concerned particularly with some topical political problems. (orig./UA) [de

Managing nuclear knowledge and expertise - An industry perspective

International Nuclear Information System (INIS)

Garderet, Ph.

2002-01-01

Full text: The industrial demand for expertise and qualified personnel in nuclear sciences and technologies will obviously continue to be strong during the next decades: in all cases, a high level of competence will necessarily continue to be required to maintain high performances in operating current nuclear facilities (up to decommissioning) ; moreover, additional skills are to be engaged to conceive new projects or to propose new services for new industrial customers. The industrial needs evidently show some quantitative or qualitative specificities according to the strategy each country has adopted in the past or is adopting now for the use of nuclear power or other nuclear technologies. But the general trends concerning the access to qualified knowledge in nuclear sciences and technologies are globally the same, so concrete actions have to be taken as soon as possible to anticipate difficult situations and overcome the problems. In the countries where nuclear industry has been strongly developed during the past decades (for example France) the problem chiefly concerns the relative ageing of the human workforce and the ability to maintain the accumulated knowledge and replace technical expertise at the very moment when all the technological companies show a significant decline in the number of entrants in all the domain of science and engineering. The problem is reinforced by the fact that (strictly for the same reasons) this phenomenon is observed concurrently within the research laboratories, among the staff of the safety authorities and, more generally, in all the offices engaged in the decision making process about nuclear affairs. Part of the solution to these serious problems stands in the human resources policy that the main nuclear industries have to achieve : internal training through enterprise universities, auto-formation, tutorage of young scientists by seniors, programs of knowledge preservation, international mobility when possible.

Available for the time being in the Russian Federation, a system of management of institutional and industrial radioactive waste (e.g. radioactive waste from industry, medicine, scientific organizations and other, which are not related to the nuclear fuel cycle or defense) provides for its collection, transportation, storage, treatment, immobilization and disposal by a network of special enterprises. Russia has 16 such enterprises. Moscow Scientific and Industrial Association Radon deals with the problems of radioactive waste from Central European part of Russia, which includes Moscow, Moscow Region and also Tverskaya, Yaroslavskaya, Vladimirskaya, Kostromskaya, Kaluzhskaya, Bryanskaya, Smolenskaya, Tulskaya, Ryazanskaya regions. The population of the central part of Russia constitutes about 40 million people. At the same time about 80% of the radioactive waste, which is collected for treatment and disposal from the territory of Russia, is included in this region. The average volume of the waste to be treated at SIA Radon is 3,000 m 3 per year for solid waste and 350 m 3 per year for liquid waste. Total radioactivity of processed waste is up to 4 PBq per year

A national industrial health service on a voluntary basis.

In Norway-a country with a population of about 3.2 million-the largest occupational group is employed in manufacturing and trade, which accounted for a total of 480 000 individuals in 1946. Most industries are small, only about 100 firms having more than 500 workers. As industry developed, there arose an increasing need for organizing a special plant health service, with the aim of protecting and promoting the health of the workers.Certain regulations were worked out, and in 1945 a general agreement was made between the Norwegian Medical Association, the Norwegian Employers' Association, and the Norwegian Federation of Labour; a tripartite body was then formed, the Board of Industrial Health Service, to give information and advice to industries. This plant health service is based on voluntary mutual agreement and not on legislation.All expenses for the plant health service are met by the industry itself. In firms with no special occupational health problems, the physician works one hour per week per 100 workers; in firms with special problems, two hours. The duties of the plant physician consist in giving the employees pre-employment and periodical health examinations, and health guidance, and carrying out other preventive measures. First aid, treatment for occupational diseases not requiring absence from work, and treatment of certain minor ailments are the only forms of therapy given at the plant. Workers in need of further medical treatment are referred to general practitioners or hospitals. Absenteeism is recorded in a uniform way in all industries that have joined this industrial health service. The plant physician has to submit an annual report on his work to the Board of Industrial Health Service.This system of industrial health service has given very good results. In 1953, 653 plants were participating with about 186 000 workers. About 260 active plant physicians are to be found in Norway at present, most of them working on a part-time basis. The cost of

To determine the anatomical and physiological nature of voice problems and their treatment in those group fitness instructors (GFIs) who have sought a medical diagnosis; the impact of voice disorders on quality of life and their contribution to activity limitations and participation restrictions; and the perceived attitudes and level of support from the industry at large in response to instructor's voice disorders and need for treatment. Prospective self-completion questionnaire design. Thirty-eight individuals (3 males and 35 females) currently active in the Australian fitness industry who had been diagnosed with a voice disorder completed an online self-completion questionnaire administered via SurveyMonkey. Laryngeal pathology included vocal fold nodules (N = 24), vocal fold cysts (N = 2), vocal fold hemorrhage (N = 1), and recurrent chronic laryngitis (N = 3). Eight individuals reported vocal strain and muscle tension dysphonia without concurrent vocal fold pathology. Treatment methods were variable, with 73.68% (N = 28) receiving voice therapy alone, 7.89% (N = 3) having voice therapy in combination with surgery, and 10.53% (N = 4) having voice therapy in conjunction with medication. Three individuals (7.89%) received no treatment for their voice disorder. During treatment, 82% of the cohort altered their teaching practices. Half of the cohort reported that their voice problems led to social withdrawal, decreased job satisfaction, and emotional distress. Greater than 65% also reported being dissatisfied with the level of industry and coworker support during the period of voice recovery. This study identifies that GFIs are susceptible to a number of voice disorders that impact their social and professional lives, and there is a need for more proactive training and advice on voice care for instructors, as well as those in management positions within the industry to address mixed approaches and opinions regarding the importance of voice care.

In part 1 of this series about problems of financing capital goods the multiple and partly diametric economic effects of financing instruments were presented using the leasing procedure as an example. The result indicated that due to the complexity of these effects the choice of a specific financing instrument requires an individual consideration. Therefore, part 2 of the series introduces the method of dynamic capital budgeting which allows the instruments discussed in part 1 to be compared with each other and helps to evaluate their economic benefits. More precisely this paper focuses on a comparative analysis of the most common alternatives, leasing, credit financing and investment financing by the state. In this context, after having identified the total costs of ownership of anesthesia devices, the final asset values of the three financing instruments can be compared with each other using the method of dynamic capital budgeting. In contrast to the prevailing opinion, the results show that from a purely fiscal perspective leasing anesthesia devices is the most expensive alternative. Given the fact that no financial support is available from the state, the option of credit financing turns out to be the most preferable alternative from a relatively limited pool of possibilities. However, it still remains to be answered whether credit financing can defend this position against further, innovative forms of debt financing (e.g., factoring, asset-backed securities, hedge funds, mezzanine capital, etc.).

During part II of this research program combustible sludge from the pulp and paper industry has been studied in detail. 560,000 tonnes of sludge per year (calculated as dry sludge) are produced in Sweden. The energy potential in the produced sludge is about 2 TWh/year. Today 1 TWh/year is produced in the pulp and paper mill's own boilers. This means that additional energy can be utilized from this material. An objective of this program has been to decide whether or not there are sludge types which are favourable respectively difficult to combust. By mixing different sludge types, or other waste products, emissions and/or problems during combustion can be minimized. These possibilities have been studied thoroughly in this program. A lot of sludge samples have been studied in laboratory scale at SP and in full-scale at Chalmers 12 MW CFB boiler. As a complement to the practical tests S.E.P. has done research regarding different aspects of sludge as a fuel; for example handling of sludge and regional drying. The results of 40 sintering tests at SP showed that the sintering temperature during combustion of sludge in a fluidised bed, with silica sand as bed material, varied between <850 deg C and >1100 deg C. The evaluation showed that the alkali content in the ash had the largest influence on the sintering temperature. Other factors were less important. During the tests at Chalmers eleven different sludge samples have been combusted together with wood pellets. Initially there were problems with the feeding to the boiler for some of the sludge samples. When the fuel feeding problems were solved the combustion took place without any problems. When sludge is co-combusted together with a 'clean' base fuel such as wood pellets the sulphur-, nitrogen- and chloride contents in the sludge have a large impact on the emissions. The normal way to reduce sulphur dioxide but also hydrogen chloride is to add lime in different positions into and after the boiler. In

2013-08-01

Full Text Available Background & Aims of the Study: Increasing hazardous industrial wastes and lack of necessary regulations for management of them have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous industrial wastes in the Khazra Industrial Park of Kerman, Iran. Materials & Methods: This study was a descriptive cross-sectional study that was done using questionnaires and local visits during year 2009. In this questionnaire, some information about the industrial wastes, production, storage on site , collection, transformation, sorting, recycling, and disposal were recorded. Results:   In the Khazra Industrial Park, 71,600 kg/day of different industrial waste is produced. The biggest proportion of waste includes metals, and construction and demolition waste which are about 16,500 tons a year. The smallest proportion is non-iron metal waste, which is produced at a rate of 8 tons per year. 88.7 percent of the active industries at the Khazra Industrial Park produce solid industrial waste. Most of the industrial units do not use a united and coordinated system for storing waste and have no specific place for temporary storage inside the industrial park. The majority of industrial waste collection, which is about 59.8%, is done by private contractors. The industrial units transfer their waste separately, and just 9 industrial units recycle their waste. Disposal of these wastes is mainly done by selling to trading agencies. Each day, 3 tons of hazardous industrial waste is produced in this park. The highest production belongs to the oil factory (Keyhan Motor. Conclusions: According to the results, the Khazra Industrial Park needs a unified system for storing, transporting and collecting the sorted waste, and it also needs to have a transportation station with basic facilities. The wastes of most industrial units at the Khazra Industrial Park have the

Lean and Virginia's wood industry - Part II: Results and need for support

Full Text Available This two-part publication about Lean practices by Viriginia’s wood products and furniture manufacturing industries reports results from researching the awareness, the implementation status, the business results, and the need for external implementation support of Virginian companies. This second manuscript focuses on business results and the need for external implementation support. Except for “sales per employee,” where less than half of respondents reported an improvement due to the implementation of Lean in their operation, a majority of respondents indicated improved business results for “lead time,” “on-time delivery,” “inventory turnover,” and “cost per unit.” With respect to the need for external Lean implementation support, only 23 percent of respondents answered in the affirmative. “Training management,” “training shop floor employees,” and “implementing [Lean] with extensive employee involvement” were, with 67, 58, and 48 percent frequencies, the most often named forms of Lean implementation support requested. Results from this study seem to indicate an opportunity to support the well-being of Virginia’s wood products and furniture manufacturing industries through improved communication of the benefits of Lean and offering specific types of training to companies.

Supply chain is a system that integrates production, inventory, distribution and information processes for increasing productivity and minimize costs. Transportation is an important part of the supply chain system, especially for supporting the material distribution process, work in process products and final products. In fact, Jakarta as the distribution center of manufacturing industries for the industrial area. Transportation system has a large influences on the implementation of supply chain process efficiency. The main problem faced in Jakarta is traffic jam that will affect on the time of distribution. Based on the system dynamic model, there are several scenarios that can provide solutions to minimize timing of distribution that will effect on the cost such as the construction of ports approaching industrial areas other than Tanjung Priok, widening road facilities, development of railways system, and the development of distribution center.

Full Text Available The selection of appropriate alternative in the industrial environment is an important but, at the same time, a complex and difficult problem because of the availability of a wide range of alternatives and similarity among them. Therefore, there is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations. In this paper, a hybrid decision making method of graph theory and matrix approach (GTMA and analytical hierarchy process (AHP is proposed. Three examples are presented to illustrate the potential of the proposed GTMA-AHP method and the results are compared with the results obtained using other decision making methods.

von Bergmann, Hubertus; Morkel, Francois; Stehmann, Timo

2015-02-01

Laser Ultrasonic Testing (UT) is an important technique for the non-destructive inspection of composite parts in the aerospace industry. In laser UT a high power, short pulse probe laser is scanned across the material surface, generating ultrasound waves which can be detected by a second low power laser system and are used to draw a defect map of the part. We report on the design and testing of a transversely excited atmospheric pressure (TEA) CO2 laser system specifically optimised for laser UT. The laser is excited by a novel solid-state switched pulsing system and utilises either spark or corona preionisation. It provides short output pulses of less than 100 ns at repetition rates of up to 1 kHz, optimised for efficient ultrasonic wave generation. The system has been designed for highly reliable operation under industrial conditions and a long term test with total pulse counts in excess of 5 billion laser pulses is reported.

Education-industry partnership: the chemical industry experience

The European Chemical Industry and the Nuclear Power Industry share similar problems and hopefully can share similar solutions to them. A recent survey of public opinion conducted on behalf of the chemical industry has shown that the general public knows little about the industry and does not trust it to behave responsibly. The industry is responding in two ways: firstly to demonstrate that it is a responsible member of the community by operating to the highest safety and environmental standards and by being open in its dealings with the public on such matters. Secondly the industry is working with the education system to ensure that the public has the opportunity to gain a good education in science, is able to make rational judgments about risks and benefits and is better able to understand and accept the role of the chemical industry in society

The organization of the automotive industry in an international context: a cost functions frontiers approach

International Nuclear Information System (INIS)

Pompeigne, J.

2003-07-01

The international automotive industry is under pinned by a dual recurrent movement of concentration and internationalization of the production. Its recent scale was the consequence of a set of strategies developed by the major auto-makers to cope with two exogenous phenomenon affecting the automotive industry. On one hand, we are talking about the saturation of the traditional automotive markets (North America, Western Europe and Japan). On the other hand, the increasing severity of the major regulations concerning the industry, notably the ones about environmental protection, is involved. The first part of the dissertation is first devoted to underline these two exogenous phenomenon, then the major strategies adopted by the auto-makers to face them are defined. Finally, the analysis turns on the resulting increase of the concentration and of the internationalization of the production. We focus on this last point and on the problem of international location of industrial activities faced by the auto-makers because of it. The second part is about providing an empirical framework to help solving these problems through parametric stochastic cost production frontiers and cost-efficiency levels. For this purpose, the analytical foundations of both of these notions are introduced, then several empirical estimation methods of a cost frontier are exposed. Finally, these methods are used to treat two real examples illustrating some of the problems about the international location of the productive activities of a major auto-maker. The point for him is to choose the most favorable configuration of its industrial system, by comparing the competing solutions through their respective cost-efficiency levels. The benefit of using additional data analysis methods to draw these comparisons is shown. (author)

Problem solving is an essential skill for nuclear engineering graduates entering the workforce. Training in qualitative and quantitative aspects of problem solving allows students to conceptualise and execute solutions to complex problems. Solutions to problems in high consequence fields of study such as nuclear engineering require rapid and accurate analysis of the problems, design of solutions (focusing on public safety, environmental stewardship and ethics), solution execution and monitoring results. A three-month course in problem solving, modelling and simulation was designed and a collaborative approach was undertaken with instructors from both industry and academia. Training was optimised for the laptop-based pedagogy, which provided unique advantages for a course that includes modelling and simulation components. The concepts and tools learned as part of the training were observed to be utilised throughout the duration of student university studies and interviews with students who have entered the workforce indicate that the approaches learned and practised are retained long term.

The role of industry: Knowledge and skills

International Nuclear Information System (INIS)

Casimir, H.B.G.

The author deals with the great progress made in technological disciplines within society in past generations. They have been the results of basic research, but there is often a lag of from 5 to 30 years between when the basic research was done, and when the technological application is truly developed. High technology uses the results of basic research, but much of this research can be very old at the time it is applied. This can be the result of missing technology between the first results and the application, or the lack of application minded effort on the part of industial science. Work in industry has drawn on a broad array of basic disciplines. Occasionally the opposite is also true, where industrial work is used in the research laboratory. In this case there is often a very short time gap, because the research scientist is always on the lookout for products which can solve particular problems for him, and obviate the need to solve these problems before concentrating on the basic research he is working on. Progress in fundamental research depends on the knowledge and skills of modern industry. That knowledge and skill exist and will continue to grow, thanks to academic research. Academic research aims primarily at discovering or creating new phenomena and at understandin them. Industrial research aims at applicable results. But nonapplicability is neither a necessary nor a sufficient criterion for inherent beauty and value

1994-03-01

To determine the optimal situation for the energy supply in the working area of the IJsselmij and Sep the study on the title subject was carried out. To influence the energy demand demand-side management (DSM) as part of integrated resource planning (IRP) is applied. Several scenarios to determine whether new production capacity must be installed or conservation options and activities should be realized are elaborated and calculated by means of the COMPASS model. E3T compiled input data for the demand-side of the model: energy consumption and energy conservation, investment cost and operational cost per user, number of installations and the development of the penetration of the conservation options between 1990 and 2010, and required subsidies and promotional costs of the IJsselmij to introduce such options. Six of the options were selected and elaborated in detail. The results are presented in this report for the options: coverage of cooling and freezing equipment at night, frequency control of electric motors, decentralized heat production by means of advanced burners, indoor climate control in the built environment, reflectors for TL-lighting systems in the built environment, and behavioral change in industrial companies. In part 1 an overview is given of the economics, the selection and elaboration of the energy conservation options. 9 figs., 53 tabs., 71 refs., 1 appendix

A problem of incentive compatibility in the North Sea petroleum industry

International Nuclear Information System (INIS)

Kashani, Hossein A.

2006-01-01

The principal-agent relationship between the governments of the UK and Norway, and the multinational oil companies active in the North Sea petroleum industry is, to some extent, different from a typical principal-agent interaction. For almost three decades, the major criterion for allowing a company to take part in the activity was its previous and planned contribution to the domestic economy by means of applying the highest possible domestic inputs. This study applies mathematical modeling to show that the authorities had the opportunity to offer an incentive scheme to persuade the oil companies to involve domestic suppliers at the governments' preferred level. Unlike a typical government regulatory framework, which aims to increase efficiency in terms of price and/or quality, the incentive compatible scheme discussed in this paper could, in certain circumstances, generate inefficiency in the daily operation of the oil and gas fields

1988-01-01

Over the past decade NRPB has had a program of work on the development of cost benefit analysis (CBA) techniques in the optimisation of radiological protection. A provisional framework for including suggestions for assigning a value to unit collective dose was published for consultation in 1981/82 and after various interim statements this process culminated in formal advice in 1986. As part of this work, and as part of a project for the Commission of the European Communities (CEC) the NRPB has carried out a number of case studies to demonstrate the practical implementation of ALARA or optimisation of protection using CBA. These techniques, used in conjunction with ALARA audits, are now in general use in the NRPB's Radiation Protection Advisor Service. They have been used for a variety of medical and industrial situations, but mainly in industrial radiography as this is the part of the non-nuclear sector where occupational exposure problems predominate. Three cases are presented as representative examples

Full Text Available The proposed paper is a continuation of the work, published in the previous issue. It is destined for specialists who are engaged in solution of problems pertaining to efficiency of light industry in Belarus which is considered as one of the branches being significantly involved in formation of national economy, its export potential and social climate. It is extremely relevant to reduce production costs in order to preserve and add strength to the branch positions in the markets. Production of natural, synthetic and knitted materials and their subsequent treatment are unreasonably power-consuming processes. Fundamental solution of the problem for reduction of production costs is to decrease its energy component and this can be achieved due to transition to modern heat and power systems in technological complexes of enterprises.The first part of the paper has considered a range of issues that served as a basis for obtaining statistical models in order to forecast the required production volume of main knitted and textile materials.  Forecasting has been prepared   for a period of more than 20 years because it has been predetermined by development horizon of comprehensive modernization of energy supply systems at enterprises of light industry. The production volumes essentially differ from those that have been stipulated in the programs of light industry.The present paper shows selection of statistical game-type for determination of  build-up rate of the production volume for every textile enterprise. The so-called “Game with Nature” has been selected as a game which is widely used for solution of analogous demand problems. The statistical forecasting models of production obtained in the first part are applied in the second part of the paper which considers strategies for development of individual enterprises. JSC :Baranovichi Industrial Cotton Association” has been taken an example in the paper. Production volumes of any enterprise are

Full Text Available Effective and efficient inventory management is the key to the economic sustainability of capital intensive modern industries. Inventory grows exponentially with complexity and size of the equipment fleet. Substantial amount of capital is required for maintaining an inventory and therefore its optimization is beneficial for smooth operation of the project at minimum cost of inventory. The size and hence the cost of the inventory is influenced by a large no of factors. This makes the optimization problem complex. This work presents a model to solve the problem of optimization of spare parts inventory. The novelty of this study lies with the fact that the developed method could tackle not only the artificial test case but also a real-world industrial problem. Various investigators developed several methods and semi-analytical tools for obtaining optimum solutions for this problem. In this study non-traditional optimization tool namely genetic algorithms GA are utilized. Apart from this Coxs regression analysis is also used to incorporate the effect of some environmental factors on the demand of spares. It shows the efficacy of the applicability of non-traditional optimization tool like GA to solve these problems. This research illustrates the proposed model with the analysis of data taken from a fleet of dumper operated in a large surface coal mine. The optimum time schedules so suggested by this GA-based model are found to be cost effective. A sensitivity analysis is also conducted for this industrial problem. Objective function is developed and the factors like the effect of season and production pressure overloading towards financial year-ending is included in the equations. Statistical analysis of the collected operational and performance data were carried out with the help of Easy-Fit Ver-5.5.The analysis gives the shape and scale parameter of theoretical Weibull distribution.

Safety management in the industry

Jaecklin, A.

1996-01-01

The safety management in the industry is characterised by the large number of processes and the materials used in them. Correspondingly large are the legal regulations. Through the thickets of today's controls, the industry moves inside a relatively tight network of technical regulations. The experience of environmental audits and industrial damage, however, shows that the greatest deficit lies in the organisational methods and less on the technical side. For the overcoming of risks one needs to recognise the weaknesses of a careful analysis. To this belongs the estimation of how far a possible scenario can be taken. The estimation of the possibilities of occurrence, however, comes up against particular problems in the industry, as the human factor in relationship with danger potentialities is very difficult to evaluate. Actual basic data or statistics are missing. This lack can only be made good with the building up of a safety management. The fundamental principles of such a management can be taken from the environmental management and especially from the standard for environmental management ISO 14001. Here it is important that safety management is integrated into the process-oriented business processes and thus becomes a part of the company culture. (author) 11 figs., tabs., 11 refs

Zeolite cations exchangers provide a unique combination of selectivity, capacity and stability not available in other ion-exchangers. In this era of environmental concern, the attractive physical and chemical properties of zeolites have been utilized worldwide in the solution to this problem. The desirable characteristics of high ion-exchange selectivity and resistance to radiolytic degradation have made certain zeolites quite useful for the separation and purification of radioisotopes from radioactive wastewater. Zeolites have also been effectively used in nuclear industry for treatment of radioactive wastes and selectively removing ammonium ions from wastewater. (author)

1979-01-01

Many ideas of image enhancement and analysis are relevant to the needs of the nondestructive testing engineer. These ideas not only aid the engineer in the performance of his current responsibilities, they also open to him new areas of industrial development and automation which are logical extensions of classical testing problems. The paper begins with a tutorial on the fundamentals of computerized image enhancement as applied to nondestructive testing, then progresses through pattern recognition and automated inspection to automated, or robotic, assembly procedures. It is believed that such procedures are cost-effective in many instances, and are but the logical extension of those techniques now commonly used, but often limited to analysis of data from quality-assurance images. Many references are given in order to help the reader who wishes to pursue a given idea further

International Nuclear Information System (INIS)

Raab, J.; Toman, V.

1999-01-01

During the recent restructuring process, the Czech steel industry has undergone a drastic reduction in the steel production by around 40%. Under such situation, previously exported volumes have been diverted into domestic markets. For the export, the Czech steel industry had to make its efforts in enhancing the quality of products and in improving the technologies in accordance with ISO standards (ISO 9000 and also ISO 14000). Among the various new quality demands in the export market, the radioactive contamination of steel products has received a very high attention. The Czech Iron and Steel Federation has organized a working team specialized in solving the problems arising from radioactive contaminated metallurgical scrap and steel products. The working team is made up of specialists from steel producers and scrap handling firms of the Czech Republic and the Slovak Republic, of experts from the State Office for Nuclear Safety, the Ministry of Industry and Trade and the Metrological Institute. Members of the Inspectorate for Ionizing Radiation and the General Directory for Customs are also included. This working team takes part in the elaboration of the legislative norms in that area. This paper deals with all the detailed functions of the working team. At present, all the major Czech steel producers have installed stationary radiation monitoring systems for detecting the possible radioactivity in all materials entering into factories. Under an agreement arranged between the producers of the Czech Iron and Steel Federation, the tolerable range of radionuclide contents in steel scrap and steel products has been set at the maximum of 100 Bq/kg in ( scrap and steel products. In this respect, the large firms collecting and treating scrap have also installed stationary radiation monitoring systems. In such monitoring systems, the detector will measure and check the values of radioactivity above 10 - 15% higher than the natural background level. In the case that

Compatibility of agriculture and petroleum industry

Problems observed in the interaction of agriculture and the petroleum industry are discussed. A wide variety of chemicals are used at drill sites. Caustic soda, chromates, asbestos, crude oil, and thread collar compound (30-50% lead) can all cause cattle poisoning. Cattle can fall into mud pits and drown. Well fracking can lead to spillage of acids onto pasture or crop land. After well production, animal poisonings can occur from salt water or lead from oil and grease, and injuries can be caused by the moving parts of the pumper unit. Salt water ingestion is a common problem, and salt concentrations >1% in drinking water can cause salt poisoning. Arsenic- and chromate-based corrosion inhibitors can cause poisoning of cattle. Broken transmission lines and leakage of petroleums allow cattle access to these substances

One of the most important impacts of industrial noise is physiological and psychological effects. The increases in workers' blood pressure and heart rate were detected during and after exposure to high levels of noise. The objectives of this research were to determine whether the noise exposures have any effects on blood pressure and heart rate of workers in the automotive parts industry. This case study was done in 2011 at different units of an automotive parts manufacturing in Tehran. Sound pressure level was measured at different units of the factory with a calibrated instrument. Demographic features of workers were gathered with an appropriate questionnaire. Heart rate and blood pressure were measured twice in a day in the start time of work day (before exposure to noise) and middle shift hours (during exposure to noise) in the occupational physician office. For analyzing data, chi-square, independent sample t-test, paired t-test, and analysis of covariance (ANCOVA) were used. P industrial noise may increase the heart rate of workers. Although rises in heart rate, systolic, and diastolic blood pressure of workers in the case group were observed after exposure to noise, the values of heart rate, systolic, and diastolic blood pressure were in the normal range. Further experimental investigations are needed to determine the relationships between these variables.

2012-10-01

Full Text Available Human resources serve as the basis for development of the national economy, as a whole, and the construction industry, as its constituent part. The problem of inferior labor productivity within the framework of the national economy and its construction industry is considered in the paper. The author has identified the reasons why the productivity of the national economy and its construction industry is low. Low quality manpower is one of the reasons. Analysis of the statistical information has proven that the quality of the manpower in the construction industry is unsatisfactory. The author has also analyzed the relation between the construction industry development pattern and the quality of the manpower. Low manpower quality is a consequence of low personnel training and development expenditures assumed by local construction companies, if compared to the same assumed in the developed economies. Russian businesses do not invest any proceeds into their employees, as any employee may leave the company at any moment, and the employer will lose the investment. Therefore, the performance rate of the Russian construction industry cannot catch up with its western counterpart. The author also provides the analysis of the western personnel development concept. The author also makes his suggestions designated to reverse the unfavourable trend of the construction industry.

A methodology is developed in diagnosing the effect of job organizational factors on job satisfaction in two automotive industries in Malaysia. One hundred and seventy male subjects of age 18-40 years with the mean age of 26.8 and standard deviation (SD) of 5.3 years and the mean work experience of 6.5 years and SD of 4.9 years took part in the study. Five job organizational factors were tested in the study including job rotation, work method, training, problem solving and goal setting. A job organization questionnaire was designed and was based on respondents' perception in relation to job satisfaction. The results showed that job organization factors were significantly related to job satisfaction. Job rotation, work method, training and goal setting showed strong correlation with job satisfaction while problem solving had intermediate correlation in the first automotive industry. On the other hand, most job organization factors showed intermediate correlation with job satisfaction in the second automotive industry except the training factor which had low correlation with job satisfaction. These results highlight that job rotation, work methods, problem solving and goal setting are outstanding factors in the study of job satisfaction for automotive industries.

A review of research on the problem of aggression inhibitors (Part II

Kalashnikova A.S.

2014-09-01

Full Text Available Many researchers in the genesis of the formation of aggressive behavior inextricably consider proagressive and constraining, or inhibiting, aggressive manifestations of structure. The second part of the article deals with a theoretical overview of the problem of aggression inhibitors, which covers the latest Russian and foreign research aimed at studying the individual manifestations of factors deterring aggression. For basis for the analysis we chose classification of personality structures inhibiting aggressive manifestations, proposed by F.S. Safuanov, which includes values, socio-normative, dispositional, emotional, communicative, intellectual restraining structure and psychological protective mechanisms. We made conclusion that the problem of aggression inhibitors currently stands on the threshold of a new phase of the study, that is to provide a holistic model, including illegal aggressive behavior, taking into account not only the socio-psychological characteristics of "aggressor" and his victims, and personality structures that promote and inhibiting aggression, but also covering a wide range of inhibitors of aggression, acting through different psychological mechanisms.

Industrial pollution of the Moselle River: the birth, development and management of an environmental problem, 1850-2000

International Nuclear Information System (INIS)

Garcier, J.R.

2005-12-01

In the 1850's, the water quality of surface waters in the Moselle river drainage basin began to suffer from the development of heavy industrial activities (coal and iron ore mining, steel and soda making). Industrial development also fuelled a demographic impetus that proved detrimental to the quality of surface waters. This study uses archival sources to analyse the ineffectiveness of the policies that were launched to regulate pollution. In a region traumatized by the Prussian annexation of a quarter of its surface (1870), industrial production enjoyed a symbolic protection that allowed water pollution to go unabated. The fuzzy status of pollution in law contributed to the immunity of industrialists. From the 1950's on, fear that the region might experience severe water shortages due to the growth of water consumption by industries and cities alike enabled more stringent policies to be devised. They still had to take into account the interests of the heavy industry and their effectiveness is questionable. Hydrological planning was based upon a functionalist vision of water resources that did not take environmental issues into account. The situation changed in the 1970's and 1980's, when European integration and the Sandoz catastrophe in the Rhine (November 1986) tipped the scale in favour of more vigorous environmental policies. This study develops the concepts of a 'regional system' and of the 'mode of construction' of an environmental problem. These prove to be valuable theoretical elements to ground environmental geography studies. (author)

Analysis of precious metals at parts-per-billion levels in industrial applications

International Nuclear Information System (INIS)

Tickner, James; O'Dwyer, Joel; Roach, Greg; Smith, Michael; Van Haarlem, Yves

2015-01-01

Precious metals, including gold and the platinum group metals (notable Pt, Pd and Rh), are mined commercially at concentrations of a few parts-per-million and below. Mining and processing operations demand sensitive and rapid analysis at concentrations down to about 100 parts-per-billion (ppb). In this paper, we discuss two technologies being developed to meet this challenge: X-ray fluorescence (XRF) and gamma-activation analysis (GAA). We have designed on-stream XRF analysers capable of measuring targeted elements in slurries with precisions in the 35–70 ppb range. For the past two years, two on-stream analysers have been in continuous operation at a precious metals concentrator plant. The simultaneous measurement of feed and waste stream grades provides real-time information on metal recovery, allowing changes in operating conditions and plant upsets to be detected and corrected more rapidly. Separately, we have been developing GAA for the measurement of gold as a replacement for the traditional laboratory fire-assay process. High-energy Bremsstrahlung X-rays are used to excite gold via the 197 Au(γ,γ′) 197 Au-M reaction, and the gamma-rays released in the decay of the meta-state are then counted. We report on work to significantly improve accuracy and detection limits. - Highlights: • X-ray fluorescence analysis at sub-parts-per-million concentration in bulk materials. • Gamma activation analysis of gold at high accuracy and low concentrations. • Use of advanced Monte Carlo techniques to optimise radiation-based analysers. • Industrial application of XRF and GAA technologies for minerals processing.

In this paper we apply stochastic programming modelling and solution techniques to planning problems for a consortium of oil companies. A multiperiod supply, transformation and distribution scheduling problem - the Depot and Refinery Optimization Problem (DROP) - is formulated for strategic or tactical level planning of the consortium's activities. This deterministic model is used as a basis for implementing a stochastic programming formulation with uncertainty in the product demands and spot supply costs (DROPS), whose solution process utilizes the deterministic equivalent linear programming problem. We employ our STOCHGEN general purpose stochastic problem generator to 'recreate' the decision (scenario) tree for the unfolding future as this deterministic equivalent. To project random demands for oil products at different spatial locations into the future and to generate random fluctuations in their future prices/costs a stochastic input data simulator is developed and calibrated to historical industry data. The models are written in the modelling language XPRESS-MP and solved by the XPRESS suite of linear programming solvers. From the viewpoint of implementation of large-scale stochastic programming models this study involves decisions in both space and time and careful revision of the original deterministic formulation. The first part of the paper treats the specification, generation and solution of the deterministic DROP model. The stochastic version of the model (DROPS) and its implementation are studied in detail in the second part and a number of related research questions and implications discussed. (author)

Potential problems in introduction of personnel reliability certification systems into Japan's nuclear industry. Implications from the German and the U.S. laws

2009-01-01

In Japan, while the interest in nuclear terrorism has increased which led law revision aiming for reinforcing physical protection in 2005, there is a growing concern in an insider threat in the nuclear industry. To cope with this threat, 'personnel reliability certification systems' are introduced in the United States and other nuclear industrized countries as an effective measure. The report examines current personnel reliability certification systems in Germany and the United States, and identifies common characteristics as well as key differences between two legal systems and regulations, and thereby attempts to identify the potential problems that the Japanese nuclear industry would face if such institutions as seen in Germany and the United States would be introduced in Japan, and suggests some measures to overcome these problems. The author suggests the following measures as practically useful essential in introducing similar systems in Japan: (1) introduction of comprehensive regulation (not industry specific) on personnel reliability certification systems, (2) clarification of conditions of prior consents by the employees, and (3) privacy protection procedures of the employees and information management.

An analysis of the dynamics of the development of wind and solar energy and potential resource restrictions of the dissemination of these technologies of energy generation associated with intensive use of rare earth metals and some other mineral resources are presented. The technological prospects of various directions of decisions of the problem of resource restrictions, including escalating of volumes of extraction and production of necessary mineral components, creating substitutes of scarce materials and development of recycling are considered. The bottlenecks of each of the above-mentioned decisions were founded. Conclusions are drawn on the prospects of development of the Russian high-tech sectors of the economy in the context of the most probable decisions of the problem of resource restrictions of wind and solar energy. An increase in extraction and production of rare earth metals and some other materials, stimulation of domestic research and development (R&D) to create the permanent magnets of new types and new technologies of wind-powered generation, and reduction of the resource-demand and technology development of recycling the components of power equipment are the most prospective directions of progress. The innovations in these directions will be in demand on the European, Chinese, and North American markets in the near decades due to the end of the life cycle (approximately 30 years) of wind and solar energy projects started at the turn of the 20th-21st centuries (the beginning of exponential growth in plants). The private investors and relevant regional and federal government agencies can use the qualitative characteristics of the dynamics of industrially assimilated renewable energy to choose the most promising investment orientations in energy projects and selection of the most economically sound development methods of energy and related industries.

There is a need for a motivated and innovative work force for the U.S. aerospace industry. The education of such engineers and scientists typically revolves around a fundamental knowledge of basic important technologies, such as the mechanics relevant to orbit-design, structures, avionics, and many others. A few years ago, the University of Michigan developed a Masters of Engineering program that provides students with skills that are not taught as part of a typical engineering curriculum. This program is focused on open problem solving, space systems, and space policy, as well as other classes that further their understanding of the connections between technologies and the nontechnical aspects of managing a space mission. The value of such an education is substantially increased through a direct connection to industry. An innovative problem-oriented approach has been developed that enables direct connections between industry and classroom teaching. The class works as a system study group and addresses problems of interest to and defined by a company with a specific application. We discuss such an application, a near-space lidar wind measurement system to enhance weather predictions, as well as the approach taken to link educational rationales.

Although there were not reasons to deplore against major activity release from any of the 110 industrial reactors authorized to operate in US, the nuclear incident that occurred at the Three Mile Island Plant in 1979 urged the public conscience toward the necessity of readiness to cope with events of this type. The personnel of the Emergency Planning Office functioning in the frame of US Department of Agriculture has already participated in around 600 intervention drillings on a federal, local or state scale to plan, test or asses radiological emergency plans or to intervene locally. These exercises allowed acquiring a significant experience in elaborating emergency plans, planning the drillings, working out scenarios and evaluation of the potential impact of accidents from the agricultural point of view. We have also taken part in different international drillings among which the most recent are INEX 1 and RADEX 94. We have found on these occasions that the agricultural problems are essential preoccupations in most of the cases no matter if the context is international, national, local or of state level. The paper poses problems specifically related to milk, fruits and vegetables, soils, meat and meat products. Finally the paper discusses issues like drilling planning, alarm and notification, sampling strategy, access authorizations for farmers, removing of contamination wastes. A number of social, political and economical relating problems are also mentioned

Production employees in the UK fragrance industry are exposed to large numbers of chemical substances and mixtures. There is a lack of published literature describing the effects of occupational respiratory exposure in this industry. To investigate whether occupational respiratory exposure to chemicals in the UK fragrance industry is linked to a statistically significant change in lung function as measured using spirometry. A multi-site cross-sectional study in which five UK companies took part, comprising an exposed group (fragrance production and associated functions) and a control group (non-exposed industry employees, e.g. office staff). Spirometric measurements (forced expiratory volume in 1 second, forced vital capacity and peak expiratory flow) were taken pre- and post-shift. Participants provided information on potential confounding factors (smoking, history of respiratory problems and body mass index). Post-shift measurements were compared between groups, using analysis of covariance to adjust for the baseline pre-shift measurements. A total of 112 subjects participated: 60 in the exposed group and 52 in control group (response rate 33 and 24%, respectively). Adjusted mean differences in post-shift spirometric measurements between exposed and control groups were not statistically significant. No significant effects were observed on the spirometric performance of the study population. This work is the first step in a novel area of research, and the industry would benefit from further such research.

Tackling optimization challenges in industrial load control and full-duplex radios

Science.gov (United States)

Gholian, Armen

In price-based demand response programs in smart grid, utilities set the price in accordance with the grid operating conditions and consumers respond to price signals by conducting optimal load control to minimize their energy expenditure while satisfying their energy needs. Industrial sector consumes a large portion of world electricity and addressing optimal load control of energy-intensive industrial complexes, such as steel industry and oil-refinery, is of practical importance. Formulating a general industrial complex and addressing issues in optimal industrial load control in smart grid is the focus of the second part of this dissertation. Several industrial load details are considered in the proposed formulation, including those that do not appear in residential or commercial load control problems. Operation under different smart pricing scenarios, namely, day-ahead pricing, time-of-use pricing, peak pricing, inclining block rates, and critical peak pricing are considered. The use of behind-the-meter renewable generation and energy storage is also considered. The formulated optimization problem is originally nonlinear and nonconvex and thus hard to solve. However, it is then reformulated into a tractable linear mixed-integer program. The performance of the design is assessed through various simulations for an oil refinery and a steel mini-mill. In the third part of this dissertation, a novel all-analog RF interference canceler is proposed. Radio self-interference cancellation (SIC) is the fundamental enabler for full-duplex radios. While SIC methods based on baseband digital signal processing and/or beamforming are inadequate, an all-analog method is useful to drastically reduce the self-interference as the first stage of SIC. It is shown that a uniform architecture with uniformly distributed RF attenuators has a performance highly dependent on the carrier frequency. It is also shown that a new architecture with the attenuators distributed in a clustered

Radioisotope technology has been used for almost half a century by the oil and gas industry to solve problems and to help optimize process operations. The use of radioactive isotopes to investigate the effectiveness of well stimulation procedures and to measure the sweep-out patterns of oil and gas in secondary recovery process is well known. The applications of radioisotopes to study features of plant and process operation has been less widely reported though the economic benefits deriving from such applications are very great. Nevertheless, there has been continuous development in the range of application and in the design of equipment to facilitate the use of the technology at remote environments such as an oil or gas platform. Some indication of the current usage of radioisotope techniques may be obtained from examination of Table I, which lists projects carried out in the UK's North Sea fields by ICI Tracerco, which is the world's largest radioisotope applications service group

2011-03-01

In the northern part of Greece, close to the city of Kavala, a phosphoric acid production industry has operated since 1965. The raw material used is the phosphate rock imported from the foreign countries. During industrial processes, naturally occurring radioactive materials (NORM) deposits exist in many facilities in the industry, causing increased levels of radiation exposure. Additionally, increased levels of NORM concentrations are also detected in the waste material of the production process, the phosphogypsum. According to the Greek Regulations for Radiation Protection (no. 216B, 5/3/2001), which is in accordance with the 96/29/EURATOM 31/5/1996, the action levels concerning the effective dose to workers at workplaces due to natural radiation sources are 1 mSv y(-1). Work activities where the corresponding doses exceed 6 mSv y(-1) are under the control of the Greek Atomic Energy Commission (GAEC). The mean yearly radon concentration action level at workplaces is 400 Bq m(-3), while the corresponding concentration limit is 3000 Bq m(-3), respectively. GAEC, according to its constitutional law, is the responsible organisation to enforce and to implement the law by means of in situ surveys and laboratory measurements. The first inspection of the area was performed in 2002 and the first measures were proposed. Periodic inspections were performed every 2 y in order to extend the operation licensing of the industry. In this work a dose assessment of the workers based on in situ and laboratory measurements is presented. In order to assess the doses to the workers the external and the internal doses are estimated.

The Advanced Industrial Materials (AIM) Program is a part of the Office of Industrial Technologies (OIT), Energy Efficiency and Renewable Energy, US Department of Energy (DOE). The mission of AIM is to support development and commercialization of new or improved materials to improve energy efficiency, productivity, product quality, and reduced waste in the major process industries. OIT has embarked on a fundamentally new way of working with industries--the Industries of the Future (IOF) strategy--concentrating on the major process industries that consume about 90% of the energy and generate about 90% of the waste in the industrial sector. These are the aluminum, chemical, forest products, glass, metalcasting, and steel industries. OIT has encouraged and assisted these industries in developing visions of what they will be like 20 or 30 years into the future, defining the drivers, technology needs, and barriers to realization of their visions. These visions provide a framework for development of technology roadmaps and implementation plans, some of which have been completed. The AIM Program supports IOF by conducting research and development on materials to solve problems identified in the roadmaps. This is done by National Laboratory/industry/university teams with the facilities and expertise needed to develop new and improved materials. Each project in the AIM Program has active industrial participation and support.

Mota, Idalia; Serrano, Daniel

2015-01-01

Presenting techniques, case-studies and methodologies that combine the use of simulation approaches with optimization techniques for facing problems in manufacturing, logistics, or aeronautical problems, this book provides solutions to common industrial problems in several fields, which range from manufacturing to aviation problems, where the common denominator is the combination of simulation’s flexibility with optimization techniques’ robustness. Providing readers with a comprehensive guide to tackle similar issues in industrial environments, this text explores novel ways to face industrial problems through hybrid approaches (simulation-optimization) that benefit from the advantages of both paradigms, in order to give solutions to important problems in service industry, production processes, or supply chains, such as scheduling, routing problems and resource allocations, among others.

Spare parts management for nuclear power generation facilities

Science.gov (United States)

Scala, Natalie Michele

With deregulation, utilities in the power sector face a much more urgent imperative to emphasize cost efficiencies as compared to the days of regulation. One major opportunity for cost savings is through reductions in spare parts inventories. Most utilities are accustomed to carrying large volumes of expensive, relatively slow-moving parts because of a high degree of risk-averseness. This attitude towards risk is rooted in the days of regulation. Under regulation, companies recovered capital inventory costs by incorporating them into the base rate charged to their customers. In a deregulated environment, cost recovery is no longer guaranteed. Companies must therefore reexamine their risk profile and develop policies for spare parts inventory that are appropriate for a competitive business environment. This research studies the spare parts inventory management problem in the context of electric utilities, with a focus on nuclear power. It addresses three issues related to this problem: criticality, risk, and policy. With respect to criticality and risk, a methodology is presented that incorporates the use of influence diagrams and the Analytic Hierarchy Process (AHP). A new method is developed for group aggregation in the AHP when Saaty and Vargas' (2007) dispersion test fails and decision makers are unwilling or unable to revise their judgments. With respect to policy, a quantitative model that ranks the importance of keeping a part in inventory and recommends a corresponding stocking policy through the use of numerical simulation is developed. This methodology and its corresponding models will enable utilities that have transitioned from a regulated to a deregulated environment become more competitive in their operations while maintaining safety and reliability standards. Furthermore, the methodology developed is general enough so that other utility plants, especially those in the nuclear sector, will be able to use this approach. In addition to regulated

The Influence Of Globalisation And Modern Technological Changes On Manufacturing Industries In Libya

Full Text Available Globalisation and new technologies are having an intense impact on the manufacturing industries. This is affecting business global and might demand new strategies and policies for manufacturing companies. Libya like several other countries in the Middle East and also is among the few developing African economies has been facing problems related to its productivity in industrial sector. Manufacturing industries in Libya was reared to offer better products and services as part of the government plans to reconstruct their economy and improve its industrial companies. So as to face these problems manufacturing sectors need to increase their production and they also require a clear strategy and policies towards an efficient supply chain about modern technology. A new technology is one of the improvement initiatives that can be used to enhance industrial performance competitiveness and decrease its costs by eliminating of waste and increasing added value activities. The significance of new technology and modern systems in the industrial world has enhanced in this decade because of the benefits that they bring to the factories and companies. The aims of this research is to investigate new technology strategies that will enable the Libyan manufacturing industries to shift towards an increase production and reduce its costs as well as to quantify the modern technological changes and the role of globalisation in addition to declaration of its effect on the growth additionally development of the Libyan industrial sector and competitiveness lastly moreover this survey make a recommendations to establish systems that improve the emergent needs of the national industrial sector.

An exploration of tutors' experiences of facilitating problem-based learning. Part 2--implications for the facilitation of problem based learning.

2003-01-01

This paper is the second of two parts exploring a study that was undertaken to investigate the role of the tutor in facilitating problem-based learning (PBL). The first part focussed on the methodological underpinnings of the study. This paper aims to focus on the findings of the study and their implications for the facilitation of PBL. Six essential themes emerged from the findings that described the facilitation role. The tutors believed that their facilitation role was essentially structured around the decision of when to intervene and how to intervene in the PBL process. Modelling and non-verbal communication were seen as essential strategies for the facilitator. Underpinning these decisions was the need to trust in the philosophy of PBL. However, within many of the themes, there was a divergence of opinion as to how the role should actually be undertaken. Despite this, these findings have implications for the future role of PBL facilitators in Health Professional Education.

Dimensional Metrology of Non-rigid Parts Without Specialized Inspection Fixtures =

Science.gov (United States)

Sabri, Vahid

Quality control is an important factor for manufacturing companies looking to prosper in an era of globalization, market pressures and technological advances. Functionality and product quality cannot be guaranteed without this important aspect. Manufactured parts have deviations from their nominal (CAD) shape caused by the manufacturing process. Thus, geometric inspection is a very important element in the quality control of mechanical parts. We will focus here on the geometric inspection of non-rigid (flexible) parts which are widely used in the aeronautic and automotive industries. Non-rigid parts can have different forms in a free-state condition compared with their nominal models due to residual stress and gravity loads. To solve this problem, dedicated inspection fixtures are generally used in industry to compensate for the displacement of such parts for simulating the use state in order to perform geometric inspections. These fixtures and the installation and inspection processes are expensive and time-consuming. Our aim in this thesis is therefore to develop an inspection method which eliminates the need for specialized fixtures. This is done by acquiring a point cloud from the part in a free-state condition using a contactless measuring device such as optical scanning and comparing it with the CAD model for the deviation identification. Using a non-rigid registration method and finite element analysis, we numerically inspect the profile of a non-rigid part. To do so, a simulated displacement is performed using an improved definition of displacement boundary conditions for simulating unfixed parts. In addition, we propose a numerical method for dimensional metrology of non-rigid parts in a free-state condition based on the arc length measurement by calculating the geodesic distance using the Fast Marching Method (FMM). In this thesis, we apply our developed methods on industrial non-rigid parts with free-form surfaces simulated with different types of

Kalsom Yusof, Umi; Nor Akmal Khalid, Mohd

2015-05-01

Semiconductor industries need to constantly adjust to the rapid pace of change in the market. Most manufactured products usually have a very short life cycle. These scenarios imply the need to improve the efficiency of capacity planning, an important aspect of the machine allocation plan known for its complexity. Various studies have been performed to balance productivity and flexibility in the flexible manufacturing system (FMS). Many approaches have been developed by the researchers to determine the suitable balance between exploration (global improvement) and exploitation (local improvement). However, not much work has been focused on the domain of machine allocation problem that considers the effects of machine breakdowns. This paper develops a model to minimize the effect of machine breakdowns, thus increasing the productivity. The objectives are to minimize system unbalance and makespan as well as increase throughput while satisfying the technological constraints such as machine time availability. To examine the effectiveness of the proposed model, results for throughput, system unbalance and makespan on real industrial datasets were performed with applications of intelligence techniques, that is, a hybrid of genetic algorithm and harmony search. The result aims to obtain a feasible solution to the domain problem.

The insurance industry and unconventional gas development: Gaps and recommendations

International Nuclear Information System (INIS)

Wetherell, Daniel; Evensen, Darrick

2016-01-01

The increasingly growing and controversial practice of natural gas development by horizontal drilling and high volume hydraulic fracturing (‘fracking’) faces a severe environmental insurance deficit at the industry level. Part of this deficit is arguably inherent to the process, whereas another part is caused by current risk information shortfalls on the processes and impacts associated with development. In the short and long terms, there are several conventional and unconventional methods by which industry-level and governmental-level policy can insure against these risks. Whilst academic attention has been afforded to the potential risks associated with unconventional natural gas development, little consideration has been given to the lack of insurance opportunities against these risks or to the additional risks promulgated by the dearth of insurance options. We chronicle the ways in which insurance options are limited due to unconventional gas development, the problems caused by lack of insurance offerings, and we highlight potential policy remedies for addressing these gaps, including a range of government- and industry-specific approaches. - Highlights: •A gap exists in provision of liability insurance for ‘fracking’-related risks. •The market gap is due primarily to uncertainties about probabilistic risk. •Insurance for risks similar to ‘fracking’ highlight potential policy options. •Government regulation and/or industry agreements can effectively fill the gap. •Policies on insurance and liability coverage necessitate ethical considerations.

Legacies of the uranium ore mining industry and their restoration. A survey of Africa, Asia and Australia

Management of the environment in the uranium mining industry has an eventful history of more than 50 years. In addition to examples of successful restoration of mining and preparation sites in some countries there are also numerous cases, in which no or defective restoration left behind serious waste deposits. In the course of the renaissance of the uranium industry there is increasing interest in the rehabilitation of such waste sites. There is still an urgent requirement to eradicate the environmental effects of the old mining industry. Previous deposits could be of interest for renewed working under the present economic boundary conditions. Restoration as an integral part of the current and future uranium mining industry with the application of modern international safety standards is extremely important. The contribution provides a survey of restoration projects of the old mining industry in various parts of the world and shows how the International Atomic Energy Agency, the national supervisory and approval authorities as well as the mining companies collaborate closely at many sites on solution of the difficult problems.

Management of Canadian mineral resources: an industry viewpoint

Energy Technology Data Exchange (ETDEWEB)

Powis, A

1976-03-01

Federal and provincial governments in Canada are developing strategies for a national mineral policy, the theme being to obtain optimum benefit for Canada from present and future use of minerals. The provisions of the British North America Act, the centerpiece of Canada's constitution, place ownership of natural resources under the jurisdiction of the province in which they are found, although it retains exclusive authority for the Federal government over the export and interprovincial trade of such resources. Contradiction and challenges are now being experienced between these two levels of government, resulting in excess taxation policies in the minerals industry. Mr. Powis discussed these issues at the 32nd Annual Conference of Provincial Ministers of Mines in Saskatoon on September 15, 1975. The roles of the private sector and governments, the Economic Council of Canada trade strategy report, the mineral area planning study, and the public and political perceptions are reviewed. Options for the future are summarized. Mr. Powis concludes that the atmosphere of confrontation in Canadian mineral policy leads to irrational management of Canadian resources; further, he sees a lack of communication between industry and government as complicating the issue. The Canadian mining industry also faces the other serious problems: (1) mining problems in inhospitable areas; (2) continuing difficulty in attracting and retaining trained labor forces; (3) increasing costs of exploration and transport; (4) competing with larger and more accessible deposits in other parts of the world; and (5) the impact of inflation in all areas of the industry.

It is pointed out that New Zealand industry has been identified as putting little effort into energy conservation. An energy conservation campaign in industry to increase efficiency and reduce wastage could have major benefits for New Zealand as a whole. Little progress in implementing energy conservation techniques in industry is apparent at present. Business decisions are in the main motivated by profits. Because of the low place of energy in industry's costs of production, seen as a single factor, it hardly rates greater priority over other established production costs. A need to integrate energy costs and material costs is apparent. The need for education is obvious, now, with cheap and limitless energy no longer existing.

This edited volume offers a state of the art overview of fast and robust solvers for the Helmholtz equation. The book consists of three parts: new developments and analysis in Helmholtz solvers, practical methods and implementations of Helmholtz solvers, and industrial applications. The Helmholtz equation appears in a wide range of science and engineering disciplines in which wave propagation is modeled. Examples are: seismic inversion, ultrasone medical imaging, sonar detection of submarines, waves in harbours and many more. The partial differential equation looks simple but is hard to solve. In order to approximate the solution of the problem numerical methods are needed. First a discretization is done. Various methods can be used: (high order) Finite Difference Method, Finite Element Method, Discontinuous Galerkin Method and Boundary Element Method. The resulting linear system is large, where the size of the problem increases with increasing frequency. Due to higher frequencies the seismic images need to b...

Economy of conservation options in the industry and the built environment. Part 1

International Nuclear Information System (INIS)

1994-03-01

To determine the optimal situation for the energy supply in the working area of the IJsselmij and Sep the study on the title subject was carried out. To influence the energy demand demand-side management (DSM) as part of integrated resource planning (IRP) is applied. Several scenarios to determine whether new production capacity must be installed or conservation options and activities should be realized are elaborated and calculated by means of the COMPASS model. E3T compiled input data for the demand-side of the model: energy consumption and energy conservation, investment cost and operational cost per user, number of installations and the development of the penetration of the conservation options between 1990 and 2010, and required subsidies and promotional costs of the IJsselmij to introduce such options. The economics of the energy conservation options are given in chapter 2. Six of the options were selected and elaborated in detail in a separate publication (part 2): coverage of cooling and freezing equipment at night, frequency control of electric motors, decentralized heat production by means of advanced burners, indoor climate control in the built environment, reflectors for TL-lighting systems in the built environment, and behavioral change in industrial companies. 2 figs., 7 tabs., 7 refs., 4 appendices

It is therefore desirable to identify and analyze weaknesses of the precursor problems (events) in order to prevent occurrence of significant events. Theoretically, significant events could be prevented from occurring if the root cause(s) of these precursor problems could be identified and eliminated. The Operating Experience Program identifies such event precursors and by reporting them to the industry, plant specific corrective actions can be taken to prevent events at other operational plants. The intent of the Operating Experience Program is therefore to improve nuclear power plant safety and reliability of the operating nuclear power plants. Each plant develops its own Operating Experience Program in order to learn from the in-house operating experience as well as from the world community of nuclear plants. The effective use of operating experience includes analyzing both plant and industry events in order to identify fundamental weaknesses and then determining appropriate plant-specific actions that will minimize the likelihood of similar events. Learning and applying the lessons from operating experience is an integral part of station safety culture and is encouraged by managers throughout the top plant administrative programs and procedures. Krsko NPP is developed it own Operating Experience Program by using the most relevant INPO/WANO/IAEA guidelines as well as its own knowledge, skills an operating practice. The Operating Experience Program is a part of the Corrective Action Program, which is among top management programs, thus program is strongly encouraged by top management. The purpose of Operating Experience Program is to provide guidance for using, sharing, and evaluating operating experience information

A Mathematical Formulation of the SCOLE Control Problem. Part 2: Optimal Compensator Design

Science.gov (United States)

Balakrishnan, A. V.

1988-01-01

The study initiated in Part 1 of this report is concluded and optimal feedback control (compensator) design for stability augmentation is considered, following the mathematical formulation developed in Part 1. Co-located (rate) sensors and (force and moment) actuators are assumed, and allowing for both sensor and actuator noise, stabilization is formulated as a stochastic regulator problem. Specializing the general theory developed by the author, a complete, closed form solution (believed to be new with this report) is obtained, taking advantage of the fact that the inherent structural damping is light. In particular, it is possible to solve in closed form the associated infinite-dimensional steady-state Riccati equations. The SCOLE model involves associated partial differential equations in a single space variable, but the compensator design theory developed is far more general since it is given in the abstract wave equation formulation. The results thus hold for any multibody system so long as the basic model is linear.

Guide to industrial respiratory protection

International Nuclear Information System (INIS)

Pritchard, J.A.

1977-03-01

The Occupational Safety and Health Act of 1970 has increased the emphasis on proper selection and use of respirators in situations where engineering controls are not feasible or are being implemented. Although a great deal of information on respiratory protection has been published, most of it is more technical than necessary for the average user faced with day-to-day problems of respiratory protection in industrial environments. This Guide is to provide the industrial user a single reference source containing enough information for establishing and maintaining a respirator program that meets the OSHA requirements outlined in 29 CFR Part 1910.134. It includes chapters on respirator selection, use, maintenance, and inspection, a complete description of all types of respirators and their advantages and limitations, and chapters on respirator fitting and wearer training, respiratory physiology, respiratory hazards, and physiological and psychological limitations. Also included are samples of the decision logic used in respirator selection, guidance on setting up an adequate respirator program through formulation of written standard operating procedures, and discussion of the meaning of the approved respirator

Design strategies for pollution prevention in industries (life cycle design)

Pollution prevention and adoption of clean technologies in the industry are to be the proper strategies to flight against the growing industrial pollution in Pakistan. These strategies will not only reduce the existing pollution load and will also help to have sustainable industrial development in Pakistan in is well established that the concept of pollution prevention demands use of minimum, resources with maximum efficiency to achieve double benefits such as resource conservation and environmental protection. The application of cleaner production and waste minimization in thousand of industries in other part of world has proved beyond doubt that the use of cleaner technology is cheaper as compared to installation of waste treatment plants for end of pipe treatment. Waste treatment plants have been blamed not to solve any pollution problem, but only to transfer pollution from one environmental media to another. The adoption of waste treatment technologies have also created lot of other problems. Thousand of industries in the world have change their focus of activities from end of pipe treatment to pollution prevention techniques. It is the right time to start pollution prevention activities in industry. The design of a product system in the industry can be represented logically as a series of decision and choices made individually and collectively by design participant. The choices range from the selection of materials and manufacturing processes to choices relating to shape, from and function of a product. The product life cycle design provides a logical system for addressing pollution prevention because the full range of environmental consequence associated with the product can be considered and it is a powerful tool for identifying and maximizing the environmental benefits of pollution prevention. The life cycle assesment (LCA) concept suggests that decision making should be based on consideration of the cradle-to grave characteristics of the product, process

Phytoremediation : an industry partner's perspective

International Nuclear Information System (INIS)

Jackson, L.A.

1999-01-01

As part of their corporate policy on environmental protection, Chevron, has taken an approach to work collaboratively with other industry members, universities and government agencies in phytoremediation research. The petroleum industry is interested in the integration of phytoremediation with the many biotechnology treatment technologies currently being used by the industry. Phytoremediation is a complex technology that does not just transfer wastes to another site, but offers in-situ final use and disposal treatment at sites anywhere in the world. Sites for potential remediation range from abandoned large refineries, chemical plants, or small urban gas stations. Research has focused on the cleanup of metals and hydrocarbons in diverse types of soil, water and groundwater conditions. This includes research into remediation of petroleum contaminants such as total petroleum hydrocarbon (TPH), polynuclear aromatic hydrocarbons as well as benzene in soil and the mechanism that occurs in the process. The ability of phytoremediation to inhibit groundwater flow and enhance degradation of TPH and volatile organic compounds in groundwater is also being studied. Chevron has developed a communication guide in order to enhance the important aspect transferring technical knowledge regarding phytoremediation into practical knowledge. Risk and cost are the two main business factors which drive the industry with regards to phytoremediation. For the risk to be small, the treatment must be both efficient and not cause problems to humans or the environment. 9 refs., 6 tabs., 1 fig

Industrial Activity at CERN

CERN Document Server

Kowalik, G

2000-01-01

The decrease in the number of CERN staff creates the need for optimization of the non-core, infrastructure-related activities. An industrial, service-orientated approach has long been considered as an appropriate way to cope with the problem of diminishing resources. This paper presents industrial and service activity issues at CERN based on the experience of the exploitation of the power network. The most important problems linked to the application of the industrial approach to the exploitation of equipment in the CERN research environment are covered. These include the interface between accelerators and electrical exploitation services, external and internal regulations, sharing of responsibility between CERN staff and external contractors, continuous modification of clients' requirements, the balance between the cost of accelerator downtime versus the cost of infrastructure upgrade. A benchmarking through a comparison with a big industrial manufacturer is followed by recommendations for possible improveme...

Problems of Recreational Industry in European Russia: Changes in Infrastructure, Environment, and Climate

Science.gov (United States)

Yakovleva, M.; Lyaskovskiy, S. I.

2011-12-01

Forest and forest-steppe zones of European Russia have a great potential for recreation, including its active form, tourism. Soft peaceful landscapes and moderate summer climate provide pleasant conditions for family vacations. Numerous lakes and rivers provide places for swimming, boating, and fishing. These pleasant environmental conditions are complemented with abundant recreational choices such as historical places, old cities, towns, and monasteries filled with museums that deliver detailed information about the millennium-long Russian history. There are the vibrant cities, Moscow and St. Petersburg; cities along the Volga River; and the oldest cities in northwestern Russia, Novgorod and Pskov provide numerous options for cultural and entertaining programs for the most demanding travelers. The country has a broad range of private tour operators that cater to national and international travelers. Still there are problems which should be taken into account by travelers who chose to spend their precious vacation time in Russia. Infrastructure problems include a deficit of three-star hotels that are the mainstream of contemporary tourist business. Their number is growing exponentially in the past decade and at present remains insufficient, but the capacity building is progressing favorably. Climatic and environmental changes became a new and unexpected factor affecting the tourist industry in European Russia. Stable and strongly sustainable climate has been interrupted by extreme events that may cause additional discomfort for some people. Tour operators and hotel hosts both need to invest more to confront incremental weather (first of all investments in air conditioning are needed) and/or have substitute travel variants that are of equivalent quality. One of the unresolved issues remains the air quality problem in Moscow due to intense traffic and the possibility of peat fires in the neighboring Shatura region southeast of the city. This increases risks that must

Full Text Available Based on comparative analysis of the industrial accident causes in Ukraine and EU countries this article establishes that the main accident reasons are organizational ones (50 to 70% of the total number of cases, however such indicators as the registered in Ukraine fatal cases frequency coefficient (per 1 thousand of employees and the fatal accidents-total accidents number ratio are greater than the similar indicators in Europe by about 2- and 100-fold, respectively. It is noted that the issues of improving the work safety in Ukraine towards the association with the European Union should be considered in the context of two main planes, which are associated with changes in the legislative and educational systems. Within this article, the authors analyse the main inter-sectoral and sectoral regulatory legal acts on labour protection, in particular in the field of providing for fire, explosion and electrical safety, and relevant documents relating to the creation and maintenance of a comfortable environment at work. Based on the conducted analysis, the problems of adapting the national legislation in the field of labour protection and industrial safety to the legal framework of EU, the problems concerning the unsystematic character and selective approach to the implementation of appropriate changes, and potential hazards that can occur at all stages of the life cycle of technical systems in the event of their introduction are determined. The main differences in the systematic approach to the professional training of students in higher educational institutions (HEI of Ukraine and EU countries (Poland, for example in the field of labour protection and industrial safety are singled out. It is noted that in the Republic of Poland numbering the population correlative with Ukraine the quantity of special educational institutions preparing specialists in the field of labour protection in relation to the total number of higher educational establishment is

Some pedo-ecological problems concerning the effects of industrial emissions on forest sites

Energy Technology Data Exchange (ETDEWEB)

Gorny, M.

1976-01-01

This study presents part of a long-term research report on the impact of emissions from a nitrogen plant upon soil zoocenoses and appraises the ecological functions of ants and earthworms. Ants (Formica polyctena) were almost the only organisms in the study area which revealed higher activity and ever increasing number of nests on the area of the strongest impact of industrial emissions. The mean increase over a 3 year period amounted to 3 nests per 10 ha per year. It was found that not only more microorganisms occurred in ant nests than in the soil adjoining them, but also that the number of active forms including those nitrogen-fixing ones, was in general, remarkably higher. This suggests the possibility that microorganisms clean the nest air of the excess of nitrogen compounds. Earthworm secretions and soil surrounding them had more abundant microflora, when compared with the soil not influenced by earthworms. The species composition of earthworm microflora in the study area within the range of industrial emissions, was entirely different from that found in earthworms from the control area. Earthworms were introduced on polluted areas along with the organic matter under an amelioration treatment. Their activity although considerable, has to be evaluated as a short-term effect, since a sexually immature population is destined for extinction. It indicates that in the course of ameliorative treatments one has to consider not only vegetation requirements, but also those of soil organisms which condition the development and life of plants.

Radiation protection, safety and associated problems in industrial radiography

International Nuclear Information System (INIS)

Le Roux, P.R.

1990-01-01

Industrial radiography is an indispensable tool for non-destructive testing. Its use entails potential radiation exposure to the operator as well as to the public. Since such radiation has the potential to be harmful, there is a need to limit radiation exposure to a level at which the risk is believed to be acceptable to the individual and to society. The Radiation Protection Society and the Department of National Health believe that the level of protection provided for radiation workers should be comparable with that in other 'safe' industries. The total risk for radiation workers includes the risk of non-radiation related accidents in the various occupations, as well as the special risks of radiation exposure. Industrial radiographers have one of the poorest safety records of all non-medical radiation workers. Operator errors and management errors seem to be the primary contributors to most accidental high exposures. It is necessary to remember that industrial radiography has to be carried out in a wide variety of work places under many different working conditions, both by day and by night. High energy end emissivity (X-ray output or source activity) is required for the radiation to be transmitted through specimens, because these are normally constructed of thick and dense materials such as steel. Additionally, most radiographic sources must be portable to permit use in field locations. On the negative side it must be mentioned that studies undertaken abroad conclude that the most important factors contributing to unsafe operations are human related. Careful planning of the method of work is essential if unnecessary risks are to be avoided. The most effective way of reducing accidents would seem to be to train employees to adhere to established and well documented procedures, to exercise common sense and sound judgement, and to use the protective equipment and devices provided in the manner specified. 2 tabs., 3 refs

Nanotechnology patents in the automotive industry (a quantitative & qualitative analysis).

Science.gov (United States)

Prasad, Raghavendra; Bandyopadhyay, Tapas K

2014-01-01

The aim of the article is to present a trend in patent filings for application of nanotechnology to the automobile sector across the world, using the keyword-based patent search. Overviews of the patents related to nano technology in the automobile industry have been provided. The current work has started from the worldwide patent search to find the patents on nanotechnology in the automobile industry and classify the patents according to the various parts of an automobile to which they are related and the solutions which they are providing. In the next step various graphs have been produced to get an insight into various trends. In next step, analysis of patents in various classifications, have been performed. The trends shown in graphs provide the quantitative analysis whereas; the qualitative analysis has been done in another section. The classifications of patents based on the solution they provide have been performed by reading the claims, titles, abstract and full texts separately. Patentability of nano technology inventions have been discussed in a view to give an idea of requirements and statutory bars to the patentability of nanotechnology inventions. Another objective of the current work is to suggest appropriate framework for the companies regarding use of nano technology in the automobile industry and a suggestive strategy for patenting of the inventions related to the same. For example, US Patent, with patent number US2008-019426A1 discusses the invention related to Lubricant composition. This patent has been studied and classified to fall under classification of automobile parts. After studying this patent, it is deduced that, the problem of friction in engine is being solved by this patent. One classification is the "automobile part" based while other is the basis of "problem being solved". Hence, two classifications, namely reduction in friction and engine were created. Similarly, after studying all the patents, a similar matrix has been created.

Roehl, Edwin A.; Conrads, Paul

2010-01-01

This is the second of two papers that describe how data mining can aid natural-resource managers with the difficult problem of controlling the interactions between hydrologic and man-made systems. Data mining is a new science that assists scientists in converting large databases into knowledge, and is uniquely able to leverage the large amounts of real-time, multivariate data now being collected for hydrologic systems. Part 1 gives a high-level overview of data mining, and describes several applications that have addressed major water resource issues in South Carolina. This Part 2 paper describes how various data mining methods are integrated to produce predictive models for controlling surface- and groundwater hydraulics and quality. The methods include: - signal processing to remove noise and decompose complex signals into simpler components; - time series clustering that optimally groups hundreds of signals into "classes" that behave similarly for data reduction and (or) divide-and-conquer problem solving; - classification which optimally matches new data to behavioral classes; - artificial neural networks which optimally fit multivariate data to create predictive models; - model response surface visualization that greatly aids in understanding data and physical processes; and, - decision support systems that integrate data, models, and graphics into a single package that is easy to use.

The results indicate that, “the optimum value for money”, “the holistic problem-solving capability of the suppliers and their high degree of performance” and “the good assistance in economically hard times in the past, which has led to a feeling of gratefulness” are all of great importance to industrial customers for building and maintaining relationships.

Environmental security: The problems of Northwestern Russia

International Nuclear Information System (INIS)

Yablokov, A.V.

1999-01-01

The review of main existing environmental problems of North-West Russia covers the radioactive pollution, atmospheric pollution, destroying of the tundra and forest ecosystems, inland and water pollution, consequences of space activities. This region includes: Karelia and Komi republics; Yamalo-Nenetzk autonomous region; Murmansk; Leningrad and Vologda regions; White Sea; Southern and eastern parts of Barents Sea; eastern part of Kara Sea; and eastern part of the Baltic (Finnish Bay). The environmental situation in northwestern Russia is extremely unsafe. The fundamental reason for this situation is Soviet over-militarization in the past. There is an urgent need now to tackle the international environmental security in the Arctic and Scandinavian regions at least in two fields: 1. The existing radioactive pollution (mostly connected with military activities), and even more dangerous - the potential radioactive pollution of the Arctic and Scandinavia. 2. Atmospheric pollution (long distance transportation of pollutant, mostly sulphur dioxide and heavy metals, from melting factories on Kola Peninsula). Several other problems relating to the environmental security of the region (among them deforestation, oil/gas pollution of the ocean, development of the diamond industry) need international attention in the nearest future. It is unrealistic to think that Russia alone can overcome these long-standing problems in the foreseeable future: we need international support for this. But foreign money for solving our environmental problems is not the solution, firstly, because for environmental restoration and recovery Russia needs much more than the international community can allocate; secondly, because there is much money inside Russia (every month, during 1993-1996, up to two billions US dollars were flowing out from Russia to western banks). To utilize this money in a proper way, we drastically need international help to awaken the Russian public environmental awareness

A numerical approach of thermal problems coupling fluid solid and radiation in complex geometries; Approche numerique de problemes thermiques couplant fluides, solides et rayonnement en geometries complexes

Energy Technology Data Exchange (ETDEWEB)

Peniguel, C; Rupp, I

1995-11-01

In many industrial problems, heat transfer does play an important part. Quite often, radiation, convection and radiation are present simultaneously. This paper presents the numerical tool handling simultaneously these phenomena. Fluid is tackled by the finite element code N3S, radiation (restricted to a non participating medium) and conduction are handled with SYRTHES respectively by a radiosity method and a finite element method. The main originality of the product is that meshes used to solve each phenomenon are completely independent. This allows users to choose the most appropriate spatial discretization for each part or phenomenon. This flexibility requires of course robust and fast data exchange procedures (temperature, convective flux, radiative flux) between the independent grids. This operation is done automatically by the code SYRTHES. One simple problem illustrating the interest of this development is presented at the end of the paper. (author). 6 refs., 8 figs.

Full Text Available Automation technology is widely accepted and rapidly growing technology in the field of core and many other industries. Anyone can observe that due to these problems many industries are turning towards automaton. When searching for problem of labor manpower in middle-case industries, we came to know about many other things like production, speed of manufacturing and quality of the product are necessary in the current scenario. These parameters are not being well maintained in incorporate industries with manual manufacturing processes instead of using automatic system. Our objective is to solve these problems by efficient use of different technologies for making an industry fully or partially automated. By using technologies we can try to solve or reduce the effects of above problems.

The convergence of electric power and natural gas industries. Mergers and acquisitions in the United States; La convergence des industries de l'electricite et du gaz naturel: les fusions-acquisitions aux Etats-Unis

Energy Technology Data Exchange (ETDEWEB)

Meritet, S

2000-07-01

Deep transformations have taken place in the US electric power industry, in terms of organisation and competition. The reforms of the regulation of this sector have changed the operation rules and, as an answer, the companies have adapted their behaviour. The reorganization is characterized by the combination between new competitive markets with new occupations. The deregulation and the technical progress accelerate the reconfiguration of the industry with the convergence of the natural gas and electric power activities. Since 1996, the numerous mergers-acquisitions between companies are representative of the tight links existing between the two energy sources. In this work, the convergence of the natural gas and power industries in the US is examined. The study of the reconciliation between power and gas companies (mainly the utilities) stresses on the improvement of the combined companies efficiency. The first part deals with the reconfiguration of the US power industry. The second part analyzes the consequences of the gas-electricity mergers and acquisitions. It includes the exploitation of financial data and a classical econometric test about the 'size-scale-spread' relation. The re-composition of the value chain is at the center of the industrial economy problem: it gives the opportunity for new forms of markets and firms. (J.S.)

The goal of steel heat treating is to provide a hardened surface on critical parts of the workpiece while keeping the rest soft and ductile in order to reduce fatigue. The high hardness is due to the phase transformation of steel accompanying the rapid cooling. This work takes into account both heating-cooling stage and viscoplastic model. Once the general mathematical formulation is derived, we can perform some numerical simulations.

The Russian Federation holds the world's largest proven natural gas reserves, and produces more natural gas than any other nation. Russian exports of gas to Europe and the other nations of the Commonwealth of Independent States (CIS) have a significant impact on natural gas markets throughout Europe and Asia. The aim of this three part study is to inform the international energy and investment community about the current status of the Russian gas industry and the prospects for its future development through 2010. It is also intended to provide an opportunity for the appropriate authorities in the Russian Federation to assess the needs of the industry and to consider areas for possible collaboration with the international investment community and international organizations in a rapidly changing economic and business environment. The study was prepared by the Energy Branch of the United Nations Department for Development Support and Management Services (UN/DDSMS). It was financed by the United Nations Development Programme (UNDP). Part I describes Russian gas reserves and potential resources, and overviews the country's gas producing, pipeline and distribution industries. Additionally, it summarizes the markets for Russian natural gas including domestic and external markets. It discusses the primary economics and potential factors that currently impact the Russian gas industry during the Federation's transition toward a market economy. Part II highlights possible directions for the development of the Russian gas resource base, including upstream gas production and downstream marketing in five-, ten- and fifteen-year time frames. It projects export opportunities for Russian Federation gas and evaluates the options for shaping regional and international markets. Part III addresses the legal and regulatory framework and fiscal regime of the Russian gas industry. It also reviews the major investment requirements and the equipment and training needs of the Russian gas

Scheduling is considered as a key task in many industries, such as project based scheduling, crew scheduling, flight scheduling, machine scheduling, etc. In the machine scheduling area, the job shop scheduling problems are considered to be important and highly complex, in which they are characterized as NP-hard. The job shop scheduling problems with late work criterion and non-preemptive jobs are addressed in this paper. Late work criterion is a fairly new objective function. It is a qualitative measure and concerns with late parts of the jobs, unlike classical objective functions that are quantitative measures. In this work, simulated annealing was presented to solve the scheduling problem. In addition, operation based representation was used to encode the solution, and a neighbourhood search structure was employed to search for the new solutions. The case studies are Lawrence instances that were taken from the Operations Research Library. Computational results of this probabilistic meta-heuristic algorithm were compared with a conventional genetic algorithm, and a conclusion was made based on the algorithm and problem.

The nuclear industry in the European Community

1990-01-01

In its reference program of 1984, the Commission presented the guidelines for the objectives in the field of nuclear electricity production within the Community. In addition, the effects have been investigated which concern the realization of these objectives for all persons involved in nuclear energy: local government, utility companies and industry. The question of nuclear energy is part of the general energy policy. Therefore, the reference program of 1984 was one of the elements which has been considered up to 1995 by the Council when defining the objectives for energy economy. The guidelines of the Commission in the reference program of 1984 are still valid today. It is important, however, to check the effects of the completion of the internal market on nuclear industry. Therefore, the Commission announced in its working program of 1989 that it will revise the reference nuclear program with regard to the prospects of the European internal market. The present document fulfills this obligation. The problems of the industry for the design and construction of nuclear power plants are treated intentionally. After the Commission for Economic and Social Affairs has given its statement, the commission will publish the document officially. (orig./UA) [de

To determine the health problems faced by labourers, 18 years and under, working in the cottage industries of Karachi and know the safety measures available and utilized at these places. Cross-sectional study using two-stage cluster sampling. From February 2002 to March 2003, 95 cottage industries from 10 different locations of five districts of Karachi were included. All workers, 18 years and below, present were interviewed. The environmental and safety gadgets present at the industry were inspected by the surveyors and the manager was interviewed for presence of health and safety benefits for the workers. A total of 280 workers were interviewed, 26 (9.3%) children were between 9-12 years, 82 (29.3%) were between 13-15 and 172 (61.4%) were between 16-18 years of age. Health benefit was given to only one 13-year-old worker in silk industry; appropriate gadgets were absent in 93 (97.8%) industries, present only in 2 industries (one silk and one loom). First Aid box was present in only one loom industry. Two hundred and forty workers (85.7%) were unaware of the materials they were using. One hundred and ninety-three (69%) children were working in improper light, 199(71%) workers experienced high level of noise, 232(83%) were working in high temperature and 155(55.3%) were working with improper ventilation. Health problems faced included joint pains (n=64, 22.85%), backache (n=85, 30.35%), vertigo (n=48, 17.14%), numbness of fingers (n=77, 27.5%) and fatigue experienced by 143 (51.07%) children. The children and adolescents employed in cottage industry are suffering from health problems due to lack of knowledge on their part, and improper ergonomics, environmental and safety conditions at the workplace. The cottage industry should be regulated and brought under labour law. The health sector non-governmental organizations should make concerted efforts for the rehabilitation of this workforce by creating awareness and providing opportunities for education and

Full Text Available Abstract An experimentation the Use of Fat from Fleshing of Leather Tanning Industry to Produce Bath Soap was aimed to use the fat from fleshing to gain the alternative source of basic material for bath soap, to assist the industry to solve the environmental pollution and increasing the population income. The point to be gained after finishing this experiment was to find out the problem solving of environmental pollution problem caused by fleshing from leather tanning industry. Goat/sheep fleshing from one of leather tannings in Yogyakarta was collected and had been used as a source of fat. Fat from fleshing was produced by 3 kinds of heating those were coocked, “kukus”, and steam. The results of fat analysis showed that the average of saphonification value was 201.01; free faty acid value was 0.86%; acid value was 1.72 and the unsaphonification fat value was 1.44%. The variations of fat used for bath soap manufacture were 55%, 60%, 65%, 70% and 75%; whereas the variations of sodium hydrokside were 11, 14, 17. 20 and 23, each of which was in parts. The result of this experiment showed that the fat from fleshing could be a source of fat and could be used for bath soap manufacture. In such way, it could be as a pollultion problem solving to the industry. The result of bath soap analysis showed that almost all of the variations of fat and sodium hydrokside could meet the SNI 06-3532-1994 about bath soap. Economically point of view showed that the value of producing fat in various regions such as Jabotabek, West Java, Center Java, DIY and East would vary from Rp6,000,000,- to Rp.200,000,000,-; whereas the value of producing bath soap would vary from Rp 21,000,000,- - Rp 700,000,000,-

Radon problem in uranium industry

International Nuclear Information System (INIS)

Khan, A.H.; Raghavayya, M.

1991-01-01

Radon emission is invariably associated with the mining and processing of uranium ores. Radon (sup(222)Rn) enters mine atmosphere through diffusion from exposed ore body, fractures and fissures in the rocks and is also brought in by ground water. Being the progenitor of a series of short lived radioisotopes it contributes over 70% of the radiation dose to mine workers and thus accounts for nearly 30% of the total radiation doses received by workers in the whole nuclear industry. This paper summarises the data on radon emanation from the ore body, backfilled sands and mine water. Radon and its progeny concentrations in different haulage levels and stopes of the Jaduguda uranium mine are presented to emphasise the need for a well planned ventilation system to control radiation exposure of miners. Results of radon monitoring from a few exploratory uranium mines are included to indicate the need for a good ventilation system from inception of the mining operations. Relative contribution of mine exhaust and tailings surfaces to the environmental radon are also given. Some instruments developed locally for monitoring of radon and its progeny in mines and in the environment are briefly described to indicate the progress made in this field.

Bednarek, R J; Featherston, H J

1984-03-01

Though the concept of employee assistance programs (EAPs) is widely accepted throughout business and industry, few hospitals have established similar channels for dealing with workers whose personal problems cause work-related problems. Among the reasons for the health care profession's lack of involvement in this area are: lack of information about costs and benefits of EAPs; the hospital's multidisciplinary environment in which standards of employee competence and behavior are set by persons from many disciplines; hospital working hours; and health care workers' attitudes about their vulnerability to illness. St. Benedict's Hospital, Ogden, UT, however, has confronted the question of how to demonstrate Christian concern for its employees. St. Benedict's EAP, the Helping Hand, which was created in 1979, combines progressive disciplinary action with the opportunity for early intervention in and treatment of employees' personal problems. When a worker with personal problems is referred to the EAP coordinator, he or she is matched with the appropriate community or hospital resource for treatment. Supervisors are trained to identify employee problems and to focus on employee job performance rather than on attempting to diagnose the problem. St. Benedict's records during the program's first three years illustrate the human benefits as well as the cost savings of an EAP. Of 92 hospital employees who took part in the EAP, 72 improved their situations or resolved their problems. The hospital's turnover rates declined from 36 percent to 20 percent, and approximately $40,800 in turnover and replacement costs were saved.

Heat recovery networks synthesis of large-scale industrial sites: Heat load distribution problem with virtual process subsystems

Highlights: • Synthesizing industrial size heat recovery network with match reduction approach. • Targeting TSI with minimum exchange between process subsystems. • Generating a feasible close-to-optimum network. • Reducing tremendously the HLD computational time and complexity. • Generating realistic network with respect to the plant layout. - Abstract: This paper presents a targeting strategy to design a heat recovery network for an industrial plant by dividing the system into subsystems while considering the heat transfer opportunities between them. The methodology is based on a sequential approach. The heat recovery opportunity between process units and the optimal flow rates of utilities are first identified using a Mixed Integer Linear Programming (MILP) model. The site is then divided into a number of subsystems where the overall interaction is resumed by a pair of virtual hot and cold stream per subsystem which is reconstructed by solving the heat cascade inside each subsystem. The Heat Load Distribution (HLD) problem is then solved between those packed subsystems in a sequential procedure where each time one of the subsystems is unpacked by switching from the virtual stream pair back into the original ones. The main advantages are to minimize the number of connections between process subsystems, to alleviate the computational complexity of the HLD problem and to generate a feasible network which is compatible with the minimum energy consumption objective. The application of the proposed methodology is illustrated through a number of case studies, discussed and compared with the relevant results from the literature

Full Text Available The purpose of this paper is to evaluate to which degree China is climbing up the technology ladder and increasing its domestic content in high tech industry. More specifically, we will assess whether China has increased its share in world trade of high tech goods and, at the same time, increased its domestic content, changing its role from a mere final assembler to a producer of more intense technology goods. We have built an indicator of domestic value added calculated as the difference between exports of final goods and imports of its parts and components. The main conclusion is that this measure has increased significantly since the early 1990ís, putting in evidence the profound changes that occurred in Chinaís high tech exports in the last two decades.

Catastrophes and Climate Change. Concerns and Possible Countermeasures of the Insurance Industry

In the last few decades, the international insurance industry has been confronted with a drastic increase in the scope and frequency of great natural disasters. The trend is primarily attributable to the continuing steady growth of the world population and the increasing concentration of people and economic values in urban areas. An additional factor is the global migration of populations and industries into areas such as coastal regions, which are particularly exposed to natural hazards. The natural hazards themselves, on the other hand, are showing a change for the worse as many atmospheric extremes are strongly influenced by global warming. In addition to the problems the insurance industry has with regard to pricing, capacity and loss reserves, the assessment of insured liabilities, preventive planning and the proper adjustment of catastrophe losses are gaining importance. The present problems will be dramatically aggravated if the greenhouse predictions come true. The changing probability distributions of many processes in the atmosphere will force up the frequency and severity of heat waves, droughts, bush fires, tropical and extratropical cyclones, tornados, hailstorms, floods and storm surges in many parts of the world with serious consequences for all types of property insurance, apart from the consequences of the stratospheric ozone destruction for health and life insurance. Rates will have to be raised and in certain areas insurance cover will only be available after considerable restrictions have been imposed, as for example significant deductibles and low liability or loss limits. In areas of high insurance density the loss potential of individual catastrophes can reach a level at which the national and international insurance industries will run into serious capacity problems. Recent disasters showed the disproportionately high participation of reinsurers in extreme disaster losses and the need for more risk transparency if the insurance industry is

Industry approach to BE applications - Past and future

With each passing year the nuclear industry, like all private industry, becomes more reliant on computer-based analysis tools. While this is primarily driven by competition and the natural advancement of computing power, computer analysis tools are also an excellent way to capture engineering know-how. As the average age of nuclear industry personnel approaches 50 years, this becomes increasingly important. The engineers that are retiring today have witnessed a remarkable evolution of computational tools during their tenure. For some, it is the difference between a pencil-and slide- rule and a desktop supercomputer. A curious aspect of this evolution is the question How has industry capitalized on all this advancement? Of course, the answer depends on who is being asked. Part of the answer must come from a historical review. This paper takes an engineer's approach to assessing history. In contrast, a mathematician's approach might be to look at where we have started and where we are today and fit a plausible story to the data. Engineers, on the other hand, have to consider other motivations. Webster Dictionary defines engineering as the application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems. Clearly, the engineers approach to any problem begins with science and math. The key difference to how an engineer approaches a problem is that 'practical', 'efficient', and 'economical' are on equal footing with 'scientific and mathematical principles'. Basically, engineers go through the same 'curve fitting' approach to every problem, but include more unknowns. Hence, the standard engineers' model is y = C 1 (science) + C 2 (math) + C 3 (practicality) + C 4 (efficiency) C 5 (economics). Computer codes used in the nuclear industry represent a broad spectrum of engineering applications including computer-aided design, structural and mechanical

Process Industry and Energy Savings

NONE

2010-07-01

Over a period of two years the NAP's Special Interest Group Energy (SIG-E) has dedicated itself to studying the way in which the process industry and its supply chain has been dealing with energy as a theme. In the past it was strongly believed that many opportunities were left unused and that different forms of cooperation inside the chain should contribute to accelerated improvement of energy efficiency in the process industry. Sixteen companies that are actively involved in the entire value chain have scrutinised their daily situation wondering how to operate more successfully. With approximately one quarter of total energy consumption the Dutch process industry is a major player in reaching national energy and climate objectives by 2020. The objective (improve energy efficiency by 2% annually) is as ambitious as that 'business as usual' is insufficient. A drastic change in how matters are approached is thus essential. The question is how to proceed? By analysing energy projects, in-depth interviews with decision makers in the industry, through literature searches and by organising lectures inside and outside the sector, SlG-E has been able to develop a true picture of the mechanisms concerning energy-related investments. Two major points of interest have been energy-oriented tendering (demand side) and the market introduction of innovations (supply side). The main problems of 'how to do more in the energy domain' is: (a) the process industry is insufficiently familiar with the capabilities of the supply chain, and (b) the supply chain is insufficiently aware of the questions that exist in the process industry. Therefore, the links in the value chain understand each other poorly. The answer to this problem is compound and consists of more interaction between the process industry and the supply chain (machine constructors, engineering firms and consultancies, education and research). As for the process industry: (a) Make improved energy

LDRD final report for improving human effectiveness for extreme-scale problem solving : assessing the effectiveness of electronic brainstorming in an industrial setting.

An experiment was conducted comparing the effectiveness of individual versus group electronic brainstorming in order to address difficult, real world challenges. While industrial reliance on electronic communications has become ubiquitous, empirical and theoretical understanding of the bounds of its effectiveness have been limited. Previous research using short-term, laboratory experiments have engaged small groups of students in answering questions irrelevant to an industrial setting. The present experiment extends current findings beyond the laboratory to larger groups of real-world employees addressing organization-relevant challenges over the course of four days. Employees and contractors at a national security laboratory participated, either in a group setting or individually, in an electronic brainstorm to pose solutions to a 'wickedly' difficult problem. The data demonstrate that (for this design) individuals perform at least as well as groups in producing quantity of electronic ideas, regardless of brainstorming duration. However, when judged with respect to quality along three dimensions (originality, feasibility, and effectiveness), the individuals significantly (p<0.05) out-performed the group working together. When idea quality is used as the benchmark of success, these data indicate that work-relevant challenges are better solved by aggregating electronic individual responses, rather than electronically convening a group. This research suggests that industrial reliance upon electronic problem solving groups should be tempered, and large nominal groups might be the more appropriate vehicle for solving wicked corporate issues.

Full Text Available The industrial policy in the UK and in Portugal, as in most EU countries, seeks to attract new investment capacity, to create jobs and to promote the impact of the so-called "demonstration efect" of "greenfield" development strategies pursued in the new plants of inward investors on existing or "brownfield" plants. This industrial policy focus is particularly evident in the automobile industry.This paper compares the industrial policy oriented towards the automobile industry in the UK and in Portugal. Two recent "greenfield" investments are analised: Nissan in the North-East region (UK and Ford/VW in the Setúbal Peninsula (Portugal, as well as three "brownfield" plants: Ford Halewood and GM Vauxhall Ellesmere Port in the North-West region (UK and Renault in Setúbal (Portugal. The first part starts with a discussion of industrial policy in the automobile sector, the role of "greenfield" development strategies and the "demonstration effect" on "brownfield" plants. Then, the limits of new inward investment are pointed out, basically their problems and restrictions. Afterwards, the structural barriers to the "demonstration effect" within "brownfield" plants are outlined and some possabilities for alternative "brownfield" development strategies are presented.

Selecting the locations and numbers of air quality monitoring stations is challenging as these are expensive to operate. Representative concentrations of pollutants in certain areas are usually determined by measuring. If there are significant correlations with concentrations of other pollutants or with other monitoring sites, however, concentrations could also be computed, partly reducing the costs. The aim of this study is to provide an overview of such possible relationships using data on concentrations of ambient air pollutants obtained in different areas of a larger city. Presented are associations between industrial (IP) and suburban parts (SP) as well as correlations between concentrations of various pollutants at the same site. Results of air pollutant monitoring come from Ostrava, an industrial city in Central Europe with a population of over 300,000. The study showed that certain pollutants were strongly correlated, especially particulate matter (r = 0.940) and ozone (r = 0.923) between the IP and SP. Statistically significant correlations were also found between different pollutants at the same site. The highest correlations were between PM 10 and NO 2 (r IP  = 0.728; r SP  = 0.734), NO 2 and benzo(a)pyrene (r IP  = 0.787; r SP  = 0.697), and NO 2 and ozone (r IP  = -0.706; r SP  = -0.686). This could contribute to more cost-effective solutions for air pollution monitoring in cities and their surroundings by using computational models based on the correlations, optimization of the network of monitoring stations, and the best selection of measuring devices.

Full Text Available When oil and biodiesel are extracted from rapeseed, secondary derived products are formed, which are not used effectively at the moment. The article deals with the problems of possible their use in food industry. During food product preparation for special dietary consumption we used electrophysical (processing by hydroelectropulse and physical (drying, grinding, steam treatment processing of raw materials. Through the developed technology for rapeseed cake processing, we received raw materials suitable for use in food industry. On the basis of these raw materials, the «Nutrition product for special dietary consumption “Ripakovyi”» was developed. It is a part of rape seed meal obtained from the seeds with low content of glucosinolates and erucic acid processed by hydroelectropulse dried in the cabinet oven or in the convective dryer, crushed and disinfected based on a developed soft technology for biologically active substances conservation. The production of this product solves the problem of rational utilization of rapeseed meal and diversification of foods for special dietary consumption.

Media and Cultural Industries: a Socioeconomic Approach

Directory of Open Access Journals (Sweden)

Bernard Miège

2008-05-01

Full Text Available This article reviews the discussion that initiated in the 70’s about the relationship between communication and information phenomena, and decisions in the economic field. This discussion, according to Miège, has been undertaken from different perspectives that have placed economy and technology at the core of the analysis. The author proposes to study these phenomena through an interdisciplinary methodology, based on the theories of cultural industries and thepolitical economy of communication. Miège argues that with industrialization of media contents, consumer product access is no longer direct and products may be available without any cost to the consumer, since the cost of informational and cultural products is paid through advertising. However, this new environment creates certain problems, such as regulating the sale of these products, turning them and their symbolic content as marketable goods or hiring intellectual and artistic workers under an unregulated framework. He also discusses a double economic operation: the sale of products to publicists, and the sale of the same products by the publicists according to the market demand. The last part of the article is an analysis made by the author on the consequences that economic changes might have on cultural industries, because of their current need to keep cooperation relationships with technological industries, as well as connections with large financial groups.

As early as 1980-1985, the geothermal energy research group of the Institute of Geology and Geophisics (Chinese Academy of Sciences) has proposed to pay attention to geothermal energy resources in oil fields. PetroChina began to study the geothermal energy resources in the region of Beijing-Tianjin-Hebei from 1995. Subsequently, the geothermal resources in the Huabei, Daqing and Liaohe oil regions were evaluated. The total recoverable hot water of the three oilfields reached 19.3 × 1011m3. PetroChina and Kenya have carried out geothermal energy development and utilization projects, with some relevant technical achievements.On the basis of many years' research on geothermal energy, we summarized the main problems in the formation and development of geothermal energy in China. First of all, China's geothermal resources research is still unable to meet the needs of the geothermal energy industry. Secondly, the development and utilization of geothermal energy requires multi-disciplinary cooperation. Thirdly, the development and utilization of geothermal energy needs consideration of local conditions. Finally, the development and utilization of geothermal energy resources requires the effective management of local government.

In an increasingly fragmented gas market, the focus for national gas safety may not rest with one major utility or gas supplier but may be spread across many companies. There will also be many new organisations in a liberalized gas industry with varying views on the needs and benefits of safety related technology development but all agree there is a need to ensure that the good safety record of gas as a domestic fuel is maintained. The number of carbon monoxide (CO) incidents is not decreasing significantly despite an increased awareness of the problem. As a consequence, a two-year joint industry programme addressing issues related to carbon monoxide has been established, co-ordinated by BG Technology and supported by gas organisations, government agencies, manufacturers and suppliers across Europe and the World. The 2-year 2 pound million programme has been constructed as twelve separate projects addressing issues such as the reporting and analysis of domestic incidents, improved service or installation practice, CO alarm reliability and information dissemination. The paper gives results and achievements of the programme, through new techniques, standards, procedures or equipment and demonstrates how the gas industry can work together to meet common safety objectives.

A concern often expressed nowadays is that the survivability of parts of the oil industry is threatened. Over the past 15 years the oil industry has experienced a succession of rapid and significant changes. The dimensions of change include oil price, of course, but also changes in activity levels, employment, supply and demand, and in economic and political conditions. In this chapter we will examine some of these changes. In this paper, the authors compare the volatility of oil prices with that of other commodities, to determine whether the oil industry environment is unique in any way. Also in this discussion the authors consider the impact of futures market trading. Second, the authors look at the performance of various parts of the industry-the upstream exploration and production sector, the refining and retailing parts of the downstream sector, as well as a brief look at consumers. last, the authors consider whether the industry has adapted to this change environment, and what we might expect in the 1990s

A continuing program for technology transfer to the apparel industry

1971-01-01

A six month program has been carried out to investigate various mechanisms for transferring technology to industry. This program has focused on transfer to the apparel industry through the Apparel Research Foundation. The procedure was to analyze the problem, obtain potentially relevant aerospace technology, and then transfer this technology to the industry organization. This was done in a specific case. Technology was identified relevant to stitchless joining, and this technology was transferred to the Apparel Research Foundation. The feasibility and ground rules for carrying out such activities on a broader scale were established. A specific objective was to transfer new technology from the industry organization to the industry itself. This required the establishment of an application engineering program. Another transfer mechanism tested was publication of solutions to industry problems in a format familiar to the industry. This is to be distinguished from circulating descriptions of new technology. Focus is on the industry problem and the manager is given a formula for solving it that he can follow. It was concluded that this mechanism can complement the problem statement approach to technology transfer. It is useful in achieving transfer when a large amount of application engineering is not necessary. A wide audience is immediately exposed to the technology. On the other hand, the major manufacturing problems which require a sophisticated technical solution integrating many innovations are less likely to be helped.

2016-10-01

Individuals who are deaf and hard-of-hearing (DHH) are underrepresented in science, technology, engineering, and mathematics (STEM) professions, and this may be due in part to their level of preparation in the development and retention of mathematical and problem-solving skills. An approach was developed that incorporates experiential learning and best practices of STEM instruction to give first-year DHH students enrolled in a postsecondary STEM program the opportunity to develop problem-solving skills in real-world scenarios. Using an industrial engineering laboratory that provides manufacturing and warehousing environments, students were immersed in real-world scenarios in which they worked on teams to address prescribed problems encountered during the activities. The highly structured, Plan-Do-Check-Act approach commonly used in industry was adapted for the DHH student participants to document and communicate the problem-solving steps. Students who experienced the intervention realized a 14.6% improvement in problem-solving proficiency compared with a control group, and this gain was retained at 6 and 12 months, post-intervention. © The Author 2016.

The convergence of electric power and natural gas industries. Mergers and acquisitions in the United States

International Nuclear Information System (INIS)

Meritet, S.

2000-01-01

Deep transformations have taken place in the US electric power industry, in terms of organisation and competition. The reforms of the regulation of this sector have changed the operation rules and, as an answer, the companies have adapted their behaviour. The reorganization is characterized by the combination between new competitive markets with new occupations. The deregulation and the technical progress accelerate the reconfiguration of the industry with the convergence of the natural gas and electric power activities. Since 1996, the numerous mergers-acquisitions between companies are representative of the tight links existing between the two energy sources. In this work, the convergence of the natural gas and power industries in the US is examined. The study of the reconciliation between power and gas companies (mainly the utilities) stresses on the improvement of the combined companies efficiency. The first part deals with the reconfiguration of the US power industry. The second part analyzes the consequences of the gas-electricity mergers and acquisitions. It includes the exploitation of financial data and a classical econometric test about the 'size-scale-spread' relation. The re-composition of the value chain is at the center of the industrial economy problem: it gives the opportunity for new forms of markets and firms. (J.S.)

Duke Power's William Lee says INPO's purpose is solving industry problems, not educating the public

Former Institute of Nuclear Power Operations (INPO) head, William Lee thinks that nuclear critics could misuse institute reports on investigations of nuclear plant construction and operation. If so, that would outweigh any public relations benefits of using the reports to inform and educate the public. Lee thinks the best way to gain public confidence is for the industry to perform well. The four-year-old institute was originally formed to improve operations, but recent problems with unfinished plants led to a system of construction audits. By offering guidance to companies building nuclear plants, INPO is meeting competition from utilities such as Duke Power, which is now marketing its expertise in designing and building plants. Lee emphasizes the importance of asking the right questions that will lead to quality control

Additive Design and Manufacturing of Jet Engine Parts

Directory of Open Access Journals (Sweden)

Pinlian Han

2017-10-01

Full Text Available The additive design (AD and additive manufacturing (AM of jet engine parts will revolutionize the traditional aerospace industry. The unique characteristics of AM, such as gradient materials and micro-structures, have opened up a new direction in jet engine design and manufacturing. Engineers have been liberated from many constraints associated with traditional methodologies and technologies. One of the most significant features of the AM process is that it can ensure the consistency of parts because it starts from point(s, continues to line(s and layer(s, and ends with the competed part. Collaboration between design and manufacturing is the key to success in fields including aerodynamics, thermodynamics, structural integration, heat transfer, material development, and machining. Engineers must change the way they design a part, as they shift from the traditional method of “subtracting material” to the new method of “adding material” in order to manufacture a part. AD is not the same as designing for AM. A new method and new tools are required to assist with this new way of designing and manufacturing. This paper discusses in detail what is required in AD and AM, and how current problems can be solved.

With this purpose there are algorithms of optimizing for positioning the parts following to be cut off from a row plate. From mathematical point of view, in positioning the parts on a raw plate the number of solutions increase four times evrey time a new part is added, and in case of finding the best solution for about few hundreds of pieces or parts would require years of processing on the most performant computers nowadays – for an analogy remember the famous story with the rice beads which the King had to pay to the master teaching him the chess: twice more for each square of the chessboard; for the total quantity assessment, King ascertained that the crops in his whole life wouldn’t have been enough.

DAIRY INDUSTRY: ALTERNATIVES TO RECOVERY WHEY AS A MEANS OF ENVIRONMENTAL MANAGEMENT

Directory of Open Access Journals (Sweden)

Liliane Marquardt

2012-01-01

Full Text Available Small and medium industries of dairy products in Brazil are facing serious problems of competition for the consumer market due to factors such as small scale production, lack of standardization of products and processes, deficiencies in effective control of quality, difficult to define niche markets and different levels of technology, although they are generating jobs and income. In addition to these factors, it appears that the control of environmental impacts caused by these industries, given the current environmental legislation, has forced a change of attitude on the part of entrepreneurs, in order to control pollution, despite the shortcomings often perceived in infrastructure linked to industrialization, such as high energy and water. The treatment and disposal of effluents and solid waste disposal, which are critical in industrial processes, are often overlooked in small and medium industries, generating significant environmental impacts. Among the main environmental impacts generated by the dairy industry stands to generate significant amounts of wastewater with high organic load. In this sense, the main objective of this study was a literature survey concerning the main factors of environmental impact of small and medium industries in the dairy sector, aiming to propose alternative environmental management that favors the minimization of the factors generating these impacts.

As regards this subject, it is useful to remember that, at the time of the designing of this plant (UP2-400), this was the only equipment available on the market with remote-controlled remote handling equipment. In the second part, before speaking about the development of remote operation equipment in the plants now under construction and attempting to project what might be the remote operation role in future plants, R. Le Guennec reviews the problems faced by engineering in designing industrial-sized processing plants and, consequently, the motivations of engineering when faced with a choice between several possible solutions [fr

The object of this paper is to study the changes in location and specialization in the European automotive industry since the mid-nineties. The analysis is based on the examination of trade flows, distinguishing between final goods and parts and components, and on the delimitation of revealed comparative advantages for those countries leading the European industry. The results show the significance of the European production networks and the increasing new Eastern member countries role in them. Besides, they allow us to establish the main participant countries competitive position in those networks. As far as the Spanish industry is concerned, two aspects must be pointed out. On the one hand, the decrease in the advantages in cars assembly although the specialization in industrial motor vehicles maintains. And on the other hand, the competitive capacity showed by some auxiliary car industries. (Author) 22 refs.

After the collapse of the Soviet Union, there has been a halt in the pace of development of the Russian electric power industry, and now the deprecation of the fixed assets increase, the degradation of energy equipment, the aging of power generation technologies, the fall in investment attractiveness and the efficiency of management of generating capacities, which can lead to mass failure equipment and emergency consequences.The conclusion. Based on the results of the study, we have the following conclusions in the need to search for new mechanisms to improve the sustainability of the electricity industry in the absence of financial resources. In the author's opinion, it is advisable to implement them on three interrelated mechanisms: revising production capacities, eliminating potentially worn-out fixed assets; the formation of common programs for the development of the electric power industry within the framework of the General Electricity Market of the Eurasian Economic Union; the construction of power plants in the border areas, due to which several national states will provide electric power. 

Why electric utilities and affiliates are handicapped in a partly regulated and partly competitive environment

Energy Technology Data Exchange (ETDEWEB)

St.Marie, S.M.

1999-11-01

As the electric utility industry continues to go through the process of restructuring, utilities are finding themselves operating not only as regulated entities but also as firms that compete for customers and sales. Some services, including services associated with distribution, are being unbundled or peeled off from the core of operations and, where possible, are being opened to competition. But these partly regulated and partly competitive areas are treacherous for utilities and their affiliates, who will be handicapped in their competitive efforts and subject to constraints not placed on their competitors. There are good reasons why such difficulties should be expected. And there are guidelines for pricing and competitive positioning that can assist in avoiding the worst problems. The first step is to recognize the archetypes of the regulated electric distribution utility and the competitive firm. In plotting their deregulation strategies, utilities and their affiliates must recognize that they will continue to be disadvantaged by regulators who are more concerned with keeping them in check than freeing them to compete.

Kang, Yoon Young [Korea Energy Economics Institute, Euiwang (Korea)

1999-12-01

Multi-industrial sector dynamic operation general equilibrium model of Korean economy has been developed. It is able to analyze carbon dioxide emission, energy use and macro economy, and reciprocal actions between each industrial sector and to measure economic effects by environmental policy for the purpose of reducing carbon dioxide. Using this model, it analyzed its effect on industries in Korea of limiting carbon dioxide emission by experimenting each policy instrument, policy object, application of tax revenue for limiting carbon dioxide. The spreading effect on each industry has a large difference for each industry. The production reduction of energy industry or large energy consuming industry (basic chemical industry, transportation and storage, steel industry, construction) shows relatively huge to other industries. Production reduction for each industry, i.e. a wide difference of economic burden between industries, will need some consideration when introducing energy carbon tax, especially in the initial stage, since it could cause an equity problem between industries. Moreover, studies on differentiating tax rate, tax return and exemption that can mitigate an equity problem between industries should be implemented. (author). 66 refs., 22 figs., 12 tabs.

Full Text Available The alignment of manufacturing strategy with the business strategy is fundamental for achieving sustainable competitive advantage. In the particular case of the automotive industry, it is verified that the production strategy of suppliers is strongly influenced by the strategy of automakers. In this context, this paper aims at presenting characteristics of the content of the production strategy of four auto parts companies besides analyzing the influence of automakers in the definition of the strategy contents.This is a descriptive and exploratory research that uses  a qualitative approach and the multi-case study method. Among the main results, it was found that the prevalent competitive priority in the companies is quality followed by delivery. In the decision areas, it was noted that customers have great influence on the quality management of these companies and in the R&D activities, besides demanding frequent deliveries. Finally, it was found that auto parts companies seek to strengthen their competitive priorities by adopting criteria from suppliers  for selecting and evaluating.

High-technology microelectronics has a major presence in countries such as China, India, Indonesia, and Malaysia, now the third-largest manufacturer of semiconductor chips. The migration of European, Japanese, and American companies accommodates regional markets. Low wage rates and limited enforcement of environmental regulations in developing countries also serve as incentives for the dramatic global migration of this industry. The manufacture of microelectonics products is accompanied by a high incidence of occupational illnesses, which may reflect the widespread use of toxic materials. Metals, photoactive chemicals, solvents, acids, and toxic gases are used in a wide variety of combinations and workplace settings. The industry also presents problems of radiation exposure and various occupational stressors, including some unresolved ergonomic issues. The fast-paced changes of the technology underlying this industry, as well as the stringent security precautions, have added to the difficulty of instituting proper health and safety measures. Epidemiologic studies reveal an alarming increase in spontaneous abortions among cleanroom manufacturing workers; no definitive study has yet identified its cause. Other health issues, including occupational cancer, are yet to be studied. The microelectronics industry is a good example of an industry that is exported to many areas of the world before health and safety problems are properly addressed and resolved.

Stijepovic, Mirko Z.; Linke, Patrick

2011-01-01

Significant energy efficiency gains in zones with concentrated activity from energy intensive industries can often be achieved by recovering and reusing waste heat between processing plants. We present a systematic approach to target waste heat recovery potentials and design optimal reuse options across plants in industrial zones. The approach first establishes available waste heat qualities and reuse feasibilities considering distances between individual plants. A targeting optimization problem is solved to establish the maximum possible waste heat recovery for the industrial zone. Then, a design optimization problem is solved to identify concrete waste heat recovery options considering economic objectives. The paper describes the approach and illustrates its application with a case study. -- Highlights: → Developed a systematic approach to target waste heat recovery potentials and to design optimal recovery and reuse options across plants in industrial zones. → Five stage approach involving data acquisition, analysis, assessment, targeting and design. → Targeting optimization problem establishes the maximum possible waste heat recovery and reuse limit for the industrial zone. → Design optimization problem provides concrete waste heat recovery and reuse network design options considering economic objectives.

Full Text Available Competitive ability of the company in modern business conditions is difficult to achieve and easy to lose. The reason for this attitude is the fact that the rapid technological improvement enabled the technology with becoming available to everyone in the world under reasonable terms. Competitiveness of domestic companies is very low. Insufficient application of knowledge, low technological level of enterprises, unproductiveness and inefficiency are just part of the problem. Food industry in Serbia shares the fate of domestic economy - non-competitiveness is one of the main factors which affect the crisis in agricultural sector. The authors of this paper, based on the available national and international statistical data, have done analysis and display of competitive opportunities of domestic economy in general and in particular sectors of food industry. The authors also indicate the possibility of improving competitiveness.

The aim of this research monograph is to present a general account of the applicability of elliptic variational inequalities to the important class of free boundary problems of obstacle type from a unifying point of view of classical Mathematical Physics.The first part of the volume introduces some obstacle type problems which can be reduced to variational inequalities. Part II presents some of the main aspects of the theory of elliptic variational inequalities, from the abstract hilbertian framework to the smoothness of the variational solution, discussing in general the properties of the free boundary and including some results on the obstacle Plateau problem. The last part examines the application to free boundary problems, namely the lubrication-cavitation problem, the elastoplastic problem, the Signorini (or the boundary obstacle) problem, the dam problem, the continuous casting problem, the electrochemical machining problem and the problem of the flow with wake in a channel past a profile.

Nowadays the problem of sustainable socio-economic development of monotowns refers to one of the priority issues of the state policy. The author analyzes monotowns state policy support in Russia with main focus on programs aimed at ecological restoration of industrial monoprofile cities. The processes of program control in monotowns within the state economic policy are analyzed. In order to evaluate the results of programs (of city-forming enterprises and monotowns level) the principles of development of criteria development system have been substantiated. The environmental situation of monotowns depends on a complex system of interaction between the city (represented by its people and municipal authorities), private capital and the state. Long-term sustainable development of monotowns requires the interests of all three parties to be in balance. This is possible to achieve by increasing the social responsibility of businesses, increasing the development of local government and urban identity and active influence of local communities on the activities of the municipal authorities.

Efforts to keep China's coal industry financially healthy and to continue increasing production also created problems in terms of output, transport, environmental damage, accidents, and labor pressures. In addition to the historical and economic reasons for these pressures, inadequate leadership and policy errors made things worse. An analysis suggests three problems: (1) an inequitable division of duties between government and business, (2) a neglected marketplace, and (3) the dominance of egalitarianism. The report relates these problems to the production of coal and a package of reforms which restructured the economic system of the industry to give it more autonomy and economic responsibility. The reforms emphasize rational pricing and use of coal as well as management of the industry.

In a mature industry all elements of the supply chain are available and are more or less in balance. Mainstream technologies are defined and well supported by a chain of specialist companies. Those specialist companies, offering services ranging from consultancy to manufacturing subcontracting, are an essential element in the industrialization. There specialization and dedication to one or a few elements in the technology increases professionalism and efficiency. The MOEMS industry however, is still in its infancy. After the birth and growth of many companies aiming at development of products, the appearance of companies aiming at the production of components and systems, we see know the first companies concentrating on the delivering of services to this industry. We can divide them in the like : * Design and Engineering companies * Foundries * Assembly and Packaging providers * Design and simulation software providers For manufacturing suppliers and customers the lack of industry standards and mainstream technologies is a serious drawback. Insight in availability and trends in technology is important to make the right choices in the field of industrialization and production. This awareness was the reason to perform a detailed study to the companies supplying commercial services in this field. This article focuses on one important part of this study: packaging and assembly. This tends to remain a bottleneck at the end of the design cycle, often delaying and sometimes preventing industrialization and commercialization. For nearly all MEMS/MST products literally everything comes together in the packaging and assembly. This is the area of full integration: electrical, mechanical, optical fluidic, magnetic etc. functionalities come together. The problems associated with the concentration of functionalities forms a big headache for the designer. Conflicting demands, of which functionality versus economics is only one, and technical hurdles have to overcome. Besides that

A report is given from the conference on new processes in the Soviet coking industry held in Moscow on 28-29 October 1982. The following papers were delivered: implementing research programs on new coking processes, new trends in coking plant design and construction in the 11th 5 year plan and in the time period until 1990, increasing efficiency of coking industry, research program of the Scientific Council in 1983. The report concentrates on new trends in coking plant design. Considering that the raw material basis of the Eastern regions of the USSR is poor in high quality coking coal the new coking processes and technologies should use weakly coking coal. The following schemes are discussed: heat treatments (especially useful in the case of black coal from the Kuzbass characterized by intensive fluctuations of petrology), selective crushing (schemes developed by the VUKhIN Institute), partial briquetting of coal mixtures (experiments carried out by the UKhIN in the Donbass in 1982). Other problems of coking such as development of new systems of smokeless fuel feeding to coke ovens, dry coke quenching, increasing capacity of coke chambers to 41.6 m/sup 3/, environmental protection in coking industry and production of special coke types from poor quality coal for metallurgy are also described.

As highlighted in the first part of this review published last month, the year 2012 saw the approval of a remarkable number of new drugs, and among the new drugs reaching the market, a significant proportion were orphan drugs developed for treating less prevalent diseases. These drugs are certainly not expected to become blockbusters, but are of high interest because of their efficacy in a narrow spectrum of patients. This trend aligns with the general tendency of staying away from fit-for-all blockbusters into personalized medicine as one of the strategies for overcoming the patent cliff that resulted in a long list of drugs going off patent and being approved as generics also during last year. The emerging scenario resulting from new developments in the form of new drugs and biosimilars and newly available generic medications paralleled by strategic movements within the pharmaceutical industry to reinforce their position in the market, as reflected by merger and acquisition deals accompanied by significant efforts into prioritization resulting in spin-off and split transactions, is reviewed in this second part. This paper includes a significant amount of data in tables for quick review and to profile the new strategic movements in drug pipelines. Further information, including details on mechanisms of action, current status, itemized pharmacology, pharmacokinetic and clinical trial research findings and updated information can be found in the proprietary databases Thomson Reuters Integrity(SM) and Thomson Reuters Cortellis™.

Many industrial problems provide scientists with important and challenging problems that need to be solved today rather than tomorrow. The key role of mathematical physics, modelling, and computational methodologies in addressing such problems continues to increase. Science has never been exogenous to applied research. Gigantic ships and steam engines, repeating catapult of Dionysius and the Antikythera `computer' invented around 80BC are just a few examples demonstrating a profound link between theoretical and applied science in the ancient world. Nowadays, many industrial problems are typically approached by groups of researchers who are working as a team bringing their expertise to the success of the entire enterprise. Since the late 1960s several groups of European mathematicians and scientists have started organizing regular meetings, seeking new challenges from industry and contributing to the solution of important industrial problems. In particular, this often took the format of week-long workshops originally initiated by the Oxford Study Groups with Industry in 1968. Such workshops are now held in many European countries (typically under the auspices of the European Study Groups with Industry - ESGI), as well as in Australia, Canada, the United States, and other countries around the world. Problems given by industrial partners are sometimes very difficult to complete within a week. However, during a week of brainstorming activities these problems inevitably stimulate developing fruitful new ideas, new approaches, and new collaborations. At the same time, there are cases where as soon as the problem is formulated mathematically, it is relatively easy to solve. Hence, putting the industrial problem into a mathematical framework, based on physical laws, often provides a key element to the success. In addition to this important first step, the value in such cases is the real, practical applicability of the results obtained for an industrial partner who presents
