  1. 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

  3. Materials in world perspective. Assessment of resources, technologies and trends for key materials industries

    Energy Technology Data Exchange (ETDEWEB)

    Altenpohl, D G

    1980-01-01

    This book deals with the entire materials cycle - from extraction or harvesting to processing, manufacture, use, and reuse or disposal. It covers the present status and ongoing developments in six key materials industries in both industrialized and developing countries. Techno-economics trends, which are recognizable today, as well as important changes taking place from the mine through the refining stage on to finished products, are outlined. The 'problem triangle' of the materials industry - basic or raw materials, ecology and energy - is discussed. Of specific importance are the impacts which a given material or technology can have on the environment. Methods of assessing these impacts, which should be integrated into overall technology planning by the materials industry, are described. This book discusses resources, industry's social responsibilities and limits-to-growth. An explanation is given for opposing views on constraints and growth, not only for the materials industry, but also for the automotive and packaging industries. Thus, this book spotlights the interaction between different fields of technology and their interrelationship with and between different regions on Earth.

  7. Renewable raw materials in the field of industry; Nachwachsende Rohstoffe in der Industrie

    Energy Technology Data Exchange (ETDEWEB)

    Peters, D.

    2006-07-01

    Being used to the practiced processing of raw materials for many decades the industry had to tap the advantage of renewable raw materials again. Conventional processing methods had to be changed and to be newly developed. This has been a rewarding task considering the ecological advantages but also considering the interesting markets for products based upon renewable raw materials. Today the German industry above all the chemical industry again processes agricultural and forestal raw materials to a considerable extent. Ten percent of the raw materials processed by the chemical industry are renewable. The wood processing industry is an important economic sector that achieves a value creation with the raw material wood exceeding the value creation of other industries by far. This brochure gives an overview of the possible substances, which are processed from renewable raw materials in Germany and it shows the important role that agricultural raw materials and wood already play for the industry nowadays.

    2017-01-01

    Full Text Available This study investigates uncertainty levels of various industries and tries to determine financial ratios having the greatest information content in determining the set of industry characteristics. It then uses these ratios to develop industry specific financial distress models. First, we employ factor analysis to determine the set of ratios that are most informative in specified industries. Second, we use a method based on the concept of entropy to measure the level of uncertainty in industries and also to single out the ratios that best reflect the uncertainty levels in specific industries. Finally, we conduct a logistic regression analysis and derive industry specific financial distress models which can be used to judge the predictive ability of selected financial ratios for each industry. The results show that financial ratios do indeed echo industry characteristics and that information content of specific ratios varies among different industries. Our findings show diverging impact of industry characteristics on companies; and thus the necessity of constructing industry specific financial distress models.

    1979-01-01

    The Congress, in the National Energy Conservation and Policy Act of 1978 (NECPA), directed the Department of Energy to establish materials recovery targets for the metals and metal products, paper and allied products, rubber, and textile-mill-products industries. The targets were developed to provide incentives for using energy-saving recorded materials and to provied a yardstick for measuring progress and improvement in this endeavor. The NECPA indicates that the targets should represent the maximum technically and economically feasible increase in the use of energy-saving recovered materials that each industry can achieve progressively by January 1, 1987. Materials affected by recovered-materials targets include and are limited to aluminum, copper, lead, zinc, iron, steel, paper and associated products, textile-mill, products, and rubber. Using information gathered from the textile-mill-products industry and from other textile-relaed sources, DOE has developed recovered materials targets for that industry. This report presents those targets and their basis and justification. Following an overview of the textile industry, the chapters are: Textile-Mill-Products Industry Operations; Economic Analysis of the Textile-Mill-Products Industry; Governmental and Regulatory Influence on the US Textile Industry; Current Mill Use of Recovered Materials in the Textile-Mill-Products Industry; Limitations on the Use of Recovered Materials in the US Textile-Mill-Products Industry; Materials-Recovery Targets; and Government and Industry Actions That Could Increase the Use of Recovered Materials.

    Full Text Available The construction as a sector of the economy is one of the largest consumers of energy resources, and the building materials industry is today one of the most energy-intensive construction industry. At the enterprises of the building materials industry the different approaches and methods are used to solve resource and energy problems. Energy saving is considered not as an complex approach in the enterprise activity, but as activity for the implementation of specific energy-saving projects, which have limitations in time and in resources. The authors suggest to use a softwareoriented approach to solving the problems of resource and energy saving. For practical application of program-oriented approach we offer to use a structuring method of the decision-making, not previously used to solve problems of resource and energy saving.

    The database for materials must address the various needs of different participants in industry. The materials producer must use the base to assure that his product meets required specifications and that his operations are under control. The designer will need the ''standard design values'' resulting from the analysis of the data, as well as the ability to examine the raw data, to assess the sensitivity of his design to postulated system conditions. Finally, the assessment of materials following extensive service must rely on this database to indicate the effect of environment on the serviceability of a given material. Encompassing all of these needs is the need to know how the data were taken; e.g., temperature control, specimen fabrication, material orientation, test machine calibration, etc. In short, the materials part of the ''common database'' is complex

With the development of theory along with computing power, quantum materials design-the synthesis of materials with the desired properties in a controlled way via materials engineering on the atomic scale-is becoming a major component of materials research. Computational prediction based on first-principles calculations has helped to find an efficient way to develop materials that are much needed for industry, as we have seen in the successful development of visible-light sensitized photocatalysts and thermoelectric materials. Close collaboration between theory and experiment is emphasized as an essential for success

  5. Case for non-material specific thermal aging

    International Nuclear Information System (INIS)

    Bessey, R.L.

    1982-01-01

    The state-of-the-art model for accelerated thermal aging of components prior to seismic testing is the Arrhenius Model. The most pertinent independent variable in the equation is the minimum activation energy constant characterizing the component aging. With minor exceptions, existing measured values of the activation energy constant are inadequate as input to the model where a material specific aging acceleration factor is to be determined, for reasons described. The model itself is not very accurate. A case is made for a statistically justified minimum activation energy constant which is not material specific. The advantages of this are assessed. The major advantage is that this would provide the industry with a practical and uniform aging method that is consistent with the accuracy of the model

    2010-01-01

    During the manufacturing process in the cement industry, raw materials of different levels of natural radioactivity are utilized. In this study we present the radiological impact of cements as a building material and the different raw materials used in their manufacture. A total of 218 samples of raw materials and their end product cements were collected from the cement industry of Macedonia (The Former Yugoslav Republic) during the period 2005-2007. The specific activities, evaluated by gamma spectrometry analysis, showed the highest mean specific activity in fly ash ( 226 Ra, 107 ± 45 Bq kg -1 ; 232 Th, 109 ± 30 Bq kg -1 ; 40 K, 685 ± 171 Bq kg -1 ), which is used as a raw material. However, the final cement product usually has relatively lower activity compared with the activity of the raw material and the mean specific activity of the final cement products were lower ( 226 Ra, 42 ± 10 Bq kg -1 ; 232 Th, 28 ± 6 Bq kg -1 ; 40 K, 264 ± 50 Bq kg -1 ). The radium equivalent activity and the hazard index were calculated for each sample to assess the radiation hazard. The mean annual effective dose originating from the cements was found to be 111 ± 22 μSv y -1 , which is below the recommended EC limit of 300 μSv y -1 .

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in FY95 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven `Vision Industries` that use about 80% of industrial energy and generated about 90% of industrial wastes. These are: aluminium; chemical; forest products; glass; metal casting; refineries; and steel. OIT is working with these industries, through appropriate organizations, to develop Visions of the desired condition of each industry some 20 to 25 years in the future and then to prepare Road Maps and Implementation Plans to enable them to reach their goals. The mission of AIM has, therefore, changed to `Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`

    1994-01-01

    Naturally occurring radioactive material (NORM) has been found in the Earth's crust and soil, the water we drink, the food we eat, the air we breathe, and the tissues of every living organism. It is relatively easy to determine open-quotes concentrationsclose quotes, or specific activity levels, in the range of 1 part per trillion for radioactive materials. With radioactive elements so abundant and detection possible at such low levels, the presence of NORM in oil and gas operations shouldn't be surprising. In fact, this presence has been recognized since at least the 1930's, but the phenomenon received only minimal attention in the United States until the mid-1980's. At that time regulatory agencies in several oil- and gas-producing states began to focus on NORM in the exploration and production segment of the industry, expressing concern over potential health and safety implications. The most significant aspects of NORM in oil production operations include original source, transport media, composition/radionuclides present, measurement methods, health/safety issues, waste classification, and waste disposal. In addition, I will summarize industry-sponsored NORM data collection and analysis efforts being conducted to aid in development of sound policies and procedures to address environmental, health, and safety issues. Current activities by state and federal regulatory agencies relevant to NORM in the oil and gas industry will also be reviewed

    Many energy-intensive process industries have complex material flows, which have a strong effect on the overall energy intensity of the final product (OEIF). This problem, however, has only been recognised qualitatively due to the lack of quantitative analysis methods. This paper presents an in-depth quantitative analysis of the effect of material flows on energy intensity in process industries. Based on the concept of a standard material flow diagram (SMFD), as used in steel manufacturing, the SMFD for a generic process industry was first developed. Then material flow scenarios were addressed in a practical material flow diagram (PMFD) using the characteristics of practical process industries. The effect of each material flow deviating from a SMFD on the OEIF was analysed. The steps involved in analysing the effect of material flows in a PMFD on its energy intensity are also discussed in detail. Finally, using 1999 statistical data from the Chinese Zhenzhou alumina refinery plant, the PMFD and SMFD for this plant were constructed as a case study. The effect of material flows on the overall energy intensity of alumina (OEIA) was thus analysed quantitatively. To decrease OEIA, the process variations which decrease the product ratios could be employed in all except in multi-supplied fraction cases. In these cases, the fractions from the stream with lower energy intensities should be increased. (author)

    Eyermann, T.J.; Sambeek, L.L. Van; Hansen, F.D.

    1995-11-01

    Sealing methods and materials currently used in salt and potash industries were surveyed to determine if systems analogous to the shaft seal design proposed for the Waste Isolation Pilot Plant (WIPP) exist. Emphasis was first given to concrete and then expanded to include other materials. Representative case studies could provide useful design, construction, and performance information for development of the WIPP shaft seal system design. This report contains a summary of engineering and construction details of various sealing methods used by mining industries for bulkheads and shaft liners. Industrial experience, as determined from site visits and literature reviews, provides few examples of bulkheads built in salt and potash mines for control of water. Sealing experiences representing site-specific conditions often have little engineering design to back up the methods employed and even less quantitative evaluation of seal performance. Cases examined include successes and failures, and both contribute to a database of experiences. Mass salt-saturated concrete placement under ground was accomplished under several varied conditions. Information derived from this database has been used to assess the performance of concrete as a seal material. Concrete appears to be a robust material with successes in several case studies. 42 refs

    Sealing methods and materials currently used in salt and potash industries were surveyed to determine if systems analogous to the shaft seal design proposed for the Waste Isolation Pilot Plant (WIPP) exist. Emphasis was first given to concrete and then expanded to include other materials. Representative case studies could provide useful design, construction, and performance information for development of the WIPP shaft seal system design. This report contains a summary of engineering and construction details of various sealing methods used by mining industries for bulkheads and shaft liners. Industrial experience, as determined from site visits and literature reviews, provides few examples of bulkheads built in salt and potash mines for control of water. Sealing experiences representing site-specific conditions often have little engineering design to back up the methods employed and even less quantitative evaluation of seal performance. Cases examined include successes and failures, and both contribute to a database of experiences. Mass salt-saturated concrete placement under ground was accomplished under several varied conditions. Information derived from this database has been used to assess the performance of concrete as a seal material. Concrete appears to be a robust material with successes in several case studies. 42 refs.

    The National Energy Conservation Policy Act of 1978 directs DOE to set targets for increased utilization of energy-saving recovered materials for certain industries. These targets are to be established at levels representing the maximum feasible increase in utilization of recovered materials that can be achieved progressively by January 1, 1987 and is consistent with technical and economic factors. A benefit to be derived from the increased use of recoverable materials is in energy savings, as state in the Act. Therefore, emhasis on different industries in the metals sector has been related to their energy consumption. The ferrous industry (iron and steel, ferrour foundries and ferralloys), as defined here, accounts for approximately 3%, and all others for the remaining 3%. Energy consumed in the lead and zinc segments is less than 1% each. Emphasis is placed on the ferrous scrap users, followed by the aluminum and copper industries. A bibliography with 209 citations is included.

    The objective of this study was to characterize physicochemical properties of airborne particulates at a monazite pulverization industry. The properties included particulate size distribution, concentration, shape, density, and radioactivity concentration. Monazite is one of the minerals containing naturally occurring radioactive material (NORM). Therefore, external and internal exposure can be occurred to the workers in monazite industry. The major exposure pathway of the workers is internal exposure due to inhalation of airborne particulates. According to International Commission on Radiological Protection (ICRP), radiation dose due to inhaled particulates containing NORM depends on particulate properties. Therefore, ICRP recommended the internal dose assessment using measured physicochemical properties of the airborne particulates. In the absence of specific information, ICRP provided default reference values. In this study, we characterized physicochemical properties of airborne particulates at a monazite pulverization industry. The databases of particulate information can be used for accurate internal dose assessment of worker.

    The Oil and Gas Production Industry began using the American Petroleum Institute's Specification Q1, ''Specification for Quality Programs'' (1st Edition, January 1, 1985) in late 1984. The generic ISO 9000 Series Standards, ''Quality management and quality assurance standards,'' were developed at about the same time and were published for public use in 1987. By late 1989 and into the early nineties, the formation of the European Economic Community and the issuance of the EC Procurement Directives sparked a rush by companies worldwide to comply with all the requirements necessary to do business in Europe. The ensuing ''ISO Mania'' has created a windfall for any company providing ISO 9000 quality system certification, consulting, training and almost anything to do with ISO 9000. It is difficult to miss one of the hundreds of newspaper and trade magazine articles promoting the ISO 9000 Quality Standards for use in almost every industry. This paper discusses the latest developments of both the lesser known API Spec Q1 and the much publicized ISO 9001 as well as discusses some of the similarities and differences between them and possible future trends. It also reviews some of the strengths and weaknesses of both documents to support the sentiment that API Spec Q1, in conjunction with the API Monogram Program, is the best quality standard for use in ordering equipment, materials and services for the Oil and Gas Industry

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven ``Vision Industries`` that use about 80% of industrial energy and generated about 90% of industrial wastes. The mission of AIM has, therefore, changed to ``Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`` Though AIM remains essentially a National Laboratory Program, it is essential that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains reasonably healthy and productive, thanks to the superb investigators and Laboratory Program Managers. This Annual Report for FY 1995 contains the technical details of some very remarkable work by the best materials scientists and engineers in the world. Areas covered here are: advanced metals and composites; advanced ceramics and composites; polymers and biobased materials; and new materials and processes.

    2009-01-06

    The overall objective of the project was to integrate advanced thermoelectric materials into a power generation device that could convert waste heat from an industrial process to electricity with an efficiency approaching 20%. Advanced thermoelectric materials were developed with figure-of-merit ZT of 1.5 at 275 degrees C. These materials were not successfully integrated into a power generation device. However, waste heat recovery was demonstrated from an industrial process (the combustion exhaust gas stream of an oxyfuel-fired flat glass melting furnace) using a commercially available (5% efficiency) thermoelectric generator coupled to a heat pipe. It was concluded that significant improvements both in thermoelectric material figure-of-merit and in cost-effective methods for capturing heat would be required to make thermoelectric waste heat recovery viable for widespread industrial application.

    In the last few years, rare earth materials (REM) prices have experienced a strong increase due to geopolitical and sustainability issues. Financial markets could already have factored in concerns about shortages of REM supplies into clean energy companies’ valuations. We use a multifactor market model for the period January 2006 to September 2012 to analyze the impact of REM price trends – specifically dysprosium and neodymium – on six clean energy indices (NYSE–BNEF) tracking the world's most important companies in the clean energy sector. The results show that during period of price increase, there is a negative relationships between REM price changes and the stock market performance of some clean energy indices. The European clean energy index is also negatively affected, and this effect could be relevant to policy makers, considering that Europe is implementing some relevant policy actions to support the development of the clean energy industry. - Highlights: • Clean energy is an industry with a double-digit growth market rate in the last years. • Rare earth materials are a key component in the development process of this industry. • Recently REMs’ prices have skyrocketed and the clean energy industry is in turmoil. • We analyze the effect of REMs price on the stock market performances of clean industry. • We find negative relation between REMs price increase and stock market performances

    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.

  16. Challenges in Materials Transformation Modeling for Polyolefins Industry

    2004-06-01

    Unlike most published polymer processing and/or forming research, the transformation of polyolefins to fabricated articles often involves non-confined flow or so-called free surface flow (e.g. fiber spinning, blown films, and cast films) in which elongational flow takes place during a fabrication process. Obviously, the characterization and validation of extensional rheological parameters and their use to develop rheological constitutive models are the focus of polyolefins materials transformation research. Unfortunately, there are challenges that remain with limited validation for non-linear, non-isothermal constitutive models for polyolefins. Further complexity arises in the transformation of polyolefins in the elongational flow system as it involves stress-induced crystallization process. The complicated nature of elongational, non-linear rheology and non-isothermal crystallization kinetics make the development of numerical methods very challenging for the polyolefins materials forming modeling. From the product based company standpoint, the challenges of materials transformation research go beyond elongational rheology, crystallization kinetics and its numerical modeling. In order to make models useful for the polyolefin industry, it is critical to develop links between molecular parameters to both equipment and materials forming parameters. The recent advances in the constrained geometry catalysis and materials sciences understanding (INSITE technology and molecular design capability) has made industrial polyolefinic materials forming modeling more viable due to the fact that the molecular structure of the polymer can be well predicted and controlled during the polymerization. In this paper, we will discuss inter-relationship (models) among molecular parameters such as polymer molecular weight (Mw), molecular weight distribution (MWD), long chain branching (LCB), short chain branching (SCB or comonomer types and distribution) and their affects on shear and

    1993-06-01

    This study was undertaken to determine the possibility of developing beneficial uses for carbon dioxide as a key component for a large-volume building product. Such a use may provide an alternative to storing the gas in oceanic sinks or clathrates as a way to slow the rate of global warming. The authors investigated the concept that carbon dioxide might be used with other chemicals to make carbon-dioxide-based polymers which would be lightweight, strong, and economical alternatives to some types of wood and silica-based building materials. As a construction-grade material, carbon dioxide would be fixed in a solid, useful form where it would not contribute to global warming. With the probable imposition of a fuel carbon tax in industrialized countries, this alternative would allow beneficial use of the carbon dioxide and could remove it from the tax basis if legislation were structured appropriately. Hence, there would be an economic driver towards the use of carbon-dioxide-based polymers which would enhance their future applications. Information was obtained through literature searches and personal contacts on carbon dioxide polymers which showed that the concept (1) is technically feasible, (2) is economically defensible, and (3) has an existing industrial infrastructure which could logically develop it. The technology exists for production of building materials which are strong enough for use by industry and which contain up to 90% by weight of carbon dioxide, both chemically and physically bound. A significant side-benefit of using this material would be that it is self-extinguishing in case of fire. This report is the first stage in the investigation. Further work being proposed will provide details on costs, specific applications and volumes, and potential impacts of this technology.

    Biopolyesters polyhydroxyalkanoates (PHA) produced by many bacteria have been investigated by microbiologists, molecular biologists, biochemists, chemical engineers, chemists, polymer experts and medical researchers. PHA applications as bioplastics, fine chemicals, implant biomaterials, medicines and biofuels have been developed and are covered in this critical review. Companies have been established or involved in PHA related R&D as well as large scale production. Recently, bacterial PHA synthesis has been found to be useful for improving robustness of industrial microorganisms and regulating bacterial metabolism, leading to yield improvement on some fermentation products. In addition, amphiphilic proteins related to PHA synthesis including PhaP, PhaZ or PhaC have been found to be useful for achieving protein purification and even specific drug targeting. It has become clear that PHA and its related technologies are forming an industrial value chain ranging from fermentation, materials, energy to medical fields (142 references).

  2. Radiation response of industrial materials: Dose-rate and morphology implications

    International Nuclear Information System (INIS)

    Berejka, Anthony J.

    2007-01-01

    Industrial uses of ionizing radiation mostly rely upon high current, high dose-rate (100 kGy/s) electron beam (EB) accelerators. To a lesser extent, industry uses low dose-rate (2.8 x 10 -3 kGy/s) radioactive Cobalt-60 as a gamma source, generally for some rather specific purposes, as medical device sterilization and the treatment of food and foodstuffs. There are nearly nine times as many (∼1400) high current EB units in commercial operation than gamma sources (∼160). However, gamma sources can be easily scaled-down so that much research on materials effects is conducted using gamma radiation. Likewise, laboratories are more likely to have very low beam current and consequently low dose-rate accelerators such as Van de Graaff generators and linear accelerators. With the advent of very high current EB accelerators, X-ray processing has become an industrially viable option. With X-rays from high power sources, dose-rates can be modulated based upon accelerator power and the attenuation of the X-ray by the distance of the material from the X-ray target. Dose and dose-rate dependence has been found to be of consequence in several commercial applications which can employ the use of ionizing radiation. The combination of dose and dose-rate dependence of the polymerization and crosslinking of wood impregnants and of fiber composite matrix materials can yield more economically viable results which have promising commercial potential. Monomer and oligomer structure also play an important role in attaining these desirable results. The influence of morphology is shown on the radiation response of olefin polymers, such as ethylene, propylene and isobutylene polymers and their copolymers. Both controlled morphology and controlled dose-rate have commercial consequences. These are also impacted both by the adroit selection of materials and through the possible use of X-ray processing

  3. Parameters for Building Materials Specifications in Lagos, Nigeria

    2013-07-01

    Full Text Available The responsibility of specifying materials for building construction purposes within Nigeria rests on the architects. Understanding the appropriate parameters for specifying building materials that could lead to immense financial proportion is required from the architects. The level of understanding and knowledge of architects is germane to the optimum performance of buildings throughout their life cycle. The methodology applied for this research involved the administration of a structured questionnaire on professional architects within the study area to determine the basis of their decision on the materials they specify or chose for building finishes. The parameters used to measure the specification of materials for finishes are client’s choice, cost, climatic compliance, and maintenance demand of materials. Findings show that the maintenance demand of materials is the most important factor that determines the specification of materials irrespective of the choice of client and climate. However, cost occupies a prominent role in the decision process. It also shows that most architects are not fully aware about the role of climate in determining the life cycle of materials in tropical environments. The compliance of materials to ever-changing climate does not constitute a major factor in the specification of materials in the area.

    1996-01-01

    The basic materials used in packaging are glass, metals (primarily aluminum and steel), an ever-growing range of plastics, paper and paperboard, wood, textiles for bags, and miscellaneous other materials (such as glues, inks, and other supplies). They are fabricated into rigid, semi-rigid, or flexible containers. The most common forms of these containers include cans, drums, bottles, cartons, boxes, bags, pouches, and wraps. Packaging products are, for the most part, low cost, bulky products that are manufactured close to their customers. There is virtually no import or export of packaging products. A material flow analysis can be developed that looks at all inputs to an industrial sector, inventories the losses in processing, and tracks the fate of the material after its useful life. An example is presented that identifies the material inputs to the packaging industry, and addresses the ultimate fate of the materials used. ?? 1996 International Association for Mathematical Geology.

    2018-02-01

    Full Text Available Different scientific studies provide many valuable recommendations how to manage crises in order to lessen their negative effect on relations with consumers. But the question whether the same business crises management rules can be applied for different industries, or they must be adapted depending on industries specifics, has not received sufficient scientific attention. Knowledge gaps about industry specific effect on consumer reactions to business crises remain. This study focuses on understanding the differences in consumers’ reactions in business crises situations with regard to controversial evaluation in the society of “the sin industries” (alcohol, tobacco, gambling, etc. and ordinary industries (not having controversial associations. Experimental research design, including online experiment with tobacco, beer and functional soft drinks consumers (in total 306 respondents, was chosen for competing research hypotheses testing. Empirical evidence was in line with theoretical argumentation about less negative consumers’ reactions during business crises in case of “sin industries” versus ordinary industry. This study shows that consumers attitudes, such as perception of company’s product quality, trust, social responsibility and behavioural intentions, such as intention to buy and recommend company’s products, are less negative during business crises in lower reputation “sin industries” than in ordinary industries.

    Highlights: • All studied industrial processes were accompanied by Cd isotope fractionation. • ϵ{sup 114/110} Cd values of the waste materials were discernible from primary sources. • Technology in use plays an important role in Cd isotope fractionation. - Abstract: Our study represents ϵ{sup 114/110} Cd {sub NIST3108} values of materials resulting from anthropogenic activities such as coal burning, smelting, refining, metal coating, and the glass industry. Additionally, primary sources (ore samples, pigment, coal) processed in the industrial premises were studied. Two sphalerites, galena, coal and pigment samples exhibited ϵ{sup 114/110} Cd{sub NIST3108} values of 1.0 ± 0.2, 0.2 ± 0.2, 1.3 ± 0.1, −2.3 ± 0.2 and −0.1 ± 0.3, respectively. In general, all studied industrial processes were accompanied by Cd isotope fractionation. Most of the industrial materials studied were clearly distinguishable from the samples used as a primary source based on ϵ{sup 114/110} Cd {sub NIST3108} values. The heaviest ϵ{sup 114/110} Cd{sub NIST3108} value of 58.6 ± 0.9 was found for slag resulting from coal combustion, and the lightest ϵ{sup 114/110} Cd{sub NIST3108} value of −23 ± 2.5 was observed for waste material after Pb refinement. It is evident that ϵ{sup 114/110} Cd {sub NIST3108} values depend on technological processes, and in case of incomplete Cd transfer from source to final waste material, every industrial activity creates differences in Cd isotope composition. Our results show that Cd isotope analysis is a promising tool to track the origins of industrial waste products.

  15. Possibilities in concrete industry towards circular economy through industrial symbiosis

    2014-01-01

    Full Text Available Major challenges of traditional linear concrete industry are utilisation of large amount of non-renewable resources and significant air emissions during production, utilisation and demolition of concrete structures. At the same time, concrete industry has a high potential for a positive shift towards more sustainable production and lower ecological footprint. One of the strategies is to use waste materials and byproducts from other industries as valuable raw materials in concrete industry. This loop can be closed only by taking into account properties of a certain waste material and using them for preparation of special purpose concrete products, in which these properties are favourable. Other strategy is designing concrete tailored for certain environment and service life, making it optimised for that specific purpose. The paper presents some of the available waste and recycled materials in Croatia and research focused on their potential application in civil engineering. The possibilities of utilisation are first explored in laboratory conditions, with the results presented in this paper as an outcome. Based on the obtained results some of the potential areas of application are proposed, in which concrete prepared with these waste materials becomes alternative to classical concrete. Both original scientific research results are presented, but also prototype of products produced based on the scientific research.

  16. Material specification for ductile cast iron in the United States

    International Nuclear Information System (INIS)

    Sorenson, K.B.

    1987-01-01

    The United States currently does not have formal design criteria for qualifying ductile cast iron (DCI) transportation casks. There is also no dedicated material standard for DCI for this particular application. Recognizing the importance of a material standard for this application, Lawrence Livermore Laboratories, in a report to the NRC, recommended that steps be taken to develop an ASTM material specification suitable for spent fuel shipping containers. A draft ASTM material specification has been written and is currently in the ASTM approval process. This paper reviews the brief history of the development of the specification, the technical basis for the material properties, the ASTM approval process and the current status of the draft specification. The expected implications of having an adopted ASTM specification on the licensing process are also discussed. The relationship of fracture toughness to composition, microstructure and tensile properties has been evaluated at Sandia National Laboratories. The first main conclusion reached is that static fracture toughness is essentially decoupled from tensile properties such as yield strength, tensile strength and ductility. The significance of this finding is that tensile properties provided for in existing DCI specifications should not be used as an indicator of a material's ability to resist crack initiation. A material specification which includes fracture toughness requirements is needed to address the brittle fracture concerns. Second, static fracture toughness was found to correlate well with material microstructure; specifically, graphite nodule count or nodule spacing

    The industrial secondary products and landmasses polluted in a minor way can be used as coverings and sealing materials and also restricted in the ground construction of landfills. By using suitable secondary products, natural materials can be reduced. Substitutes are needed due to the fact that the availability of natural materials is poor in many areas. The presented project is a part of the Streams technology programme financed by Tekes. It includes the development of the measuring methods to study the environmental suitability of industrial secondary products, which will be used as covering materials of landfills. Based on the results, a handbook addressing the environmental suitability procedure will be compiled

  1. Problems in complying with regulations related to low activity materials: Industry, medical, research

    International Nuclear Information System (INIS)

    Steen, J. van der

    1997-01-01

    The new Basic Safety Standards (BSS) for protection against ionizing radiation and for the safety of radiation sources contain nuclide specific exemption levels on reporting. In many cases, these exemption levels differ orders of magnitude, higher or lower, compared to those from the old standards. For the natural radionuclides, the exempted specific activity is much lower (10 or even 1 Bq/g, depending on the radionuclide, compared to 500 Bq/g in the old BSS). As a consequence, industrial activities with certain minerals or raw materials containing elevated concentrations of radionuclides, which were exempted from the radiation protection control system under the old BSS, may have to be declared as radiologically relevant activities and may now come under regulatory control. Examples of these activities are the phosphate ore processing, the refining of a number of metals, the use of slag, and the oil and natural gas production. This might give rise, in some cases, to large volumes of waste which should be treated, conditioned and disposed of in a controlled way. For artificial radionuclides with higher exemption levels, the use of such radionuclides for industrial, medical or research purposes, such as tracers, sealed sources and beta lights, may increase considerably without being controlled any longer by the regulatory system.

  3. Economics of production of biogas from specifically-grown plant material. [New Zealand

    Energy Technology Data Exchange (ETDEWEB)

    Stewart, D. J.

    1977-10-15

    The production of biogas from plant materials is technologically very simple, and is the only process currently available (other than direct burning) for conversion of cellulose materials into energy or fuels that is feasible at a farm-scale, or even a home-scale, as well as a large industrial plant scale. For this reason the economics of biogas production can be considered at the farm-scale as well as the industrial scale. An accurate assessment of the economics at the farm-scale is possible, because commercially produced units are now available in New Zealand and in operation. However, although large-scale plants have been proposed and costed in the USA for the conversion of the cellulose component of garbage into biogas, operational data are not yet available, and the costing has not been applied to the use of specifically-grown plant material. Nevertheless, the large-scale plants envisaged use a large number of digesters each of 100,000 gallons capacity and can thus be regarded as a combination of farm-size units, although with some economics in digester size, number of pumps required, etc. For these reasons, this review of the economics of biogas production is based on the operation of commercial 20,000 gallon digesters available in NZ for farm-scale use. Factors governing the economics of farm-scale and industrial-scale production of biogas will be discussed in section 6.

    Full Text Available There is a common perception that logistics practice and supply chain management have not yet reached the required international standards among all the supply chain members in the South African automotive industry. This article is based on a research study that investigated possible reasons for the inconsistent supply of materials in the Eastern Cape automotive industry specifically. Problems identified include the fact that suppliers are not evaluated on a regular basis and do not receive sufficient logistics training, while a commitment and will to development local suppliers is lacking. Recommendations made to the South African automotive industry include the improvement of development programmes to assist local suppliers in becoming world-class suppliers, better logistics training, more regular supplier assessments, as well as improved mutual communication among suppliers and motor vehicle assemblers.

    Industrial symbiosis is a collaboration of several industries to share their necessities such material, energy, technology as well as waste management. As a part of industrial ecology, in principle, this system attempts to emulate ecosystem where waste of an organism is being used by another organism, therefore there is no waste in the nature. This system becomes an effort to optimize resources (material and energy) as well as minimize waste. Considerable, in a symbiosis incure material and energy flows among industries. Material and energy in an industry are known as cost carriers, thus flow analysis in this system can be conducted in perspective of material, energy and cost, or called as material flow cost accounting (MFCA) that is an economic and ecological appraisal approach. Previous researches shown that MFCA implementation could be used to evaluate an industry's environmental-related efficiency as well as in planning, business control and decision making. Moreover, the MFCA has been extended to assess environmental performance of SMEs Cluster or industrial symbiosis in SMEs Cluster, even to make preliminary design of an industrial symbiosis base on a major industry. This paper describes the use of MFCA to asses performance of SMEs industrial symbiosis and to improve the performance.

    A workshop, 'Theory Meets Industry', was held on 12-14 June 2007 in Vienna, Austria, attended by a well balanced number of academic and industrial scientists from America, Europe, and Japan. The focus was on advances in ab initio solid state calculations and their practical use in industry. The theoretical papers addressed three dominant themes, namely (i) more accurate total energies and electronic excitations (ii) more complex systems, and (iii) more diverse and accurate materials properties. Hybrid functionals give some improvements in energies, but encounter difficulties for metallic systems. Quantum Monte Carlo methods are progressing, but no clear breakthrough is on the horizon. Progress in order-N methods is steady, as is the case for efficient methods for exploring complex energy hypersurfaces and large numbers of structural configurations. The industrial applications were dominated by materials issues in energy conversion systems, the quest for hydrogen storage materials, improvements of electronic and optical properties of microelectronic and display materials, and the simulation of reactions on heterogeneous catalysts. The workshop is a clear testimony that ab initio computations have become an industrial practice with increasingly recognized impact

    1980-01-01

    An analysis is made of the existing methods of calculating specific capital investments in the fuel extracting sectors of industry. Their shortcomings are shown. It is suggested that specific capital investments for extraction of coal and gas be defined as the ratio of capital investments to the conditional increase in extraction. Coal extraction should take int consideration all the capital investments associated with the input of new facilities, and the maintenance of the attained level of extraction and reconstruction of the enterprise, as well as all the newly introduced facilities both at the new and at the active enterprises associated with an increase in coal extraction and with maintenance of the facilities. The suggested technique completely corresponds to the ''Standard Technique for Developing a Technical-Industrial-Financial Plan,'' which stipulates determination of specific capital investments per unit of introduced facilities with only the difference that it takes into consideration the specific features of the fuel extracting sectors of industry.

    1996-04-01

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven ``Vision Industries`` that use about 80% of industrial energy and generated about 90% of industrial wastes. The mission of AIM has, therefore, changed to ``Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`` Though AIM remains essentially a National Laboratory Program, it is essential that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains reasonably healthy and productive, thanks to the superb investigators and Laboratory Program Managers. This report contains the technical details of some very remarkable work by the best materials scientists and engineers in the world. Subject areas covered are: advanced metals and composites; advanced ceramics and composites; polymers and biobased materials; and new materials and processes.

    1997-01-01

    The emergence of new analytical technology and the production of pharmaceuticals for a global market in a cost-effective manner necessitate the establishment of worldwide specifications that are appropriate for the product and the manufacturing process. This requires a thorough knowledge of the protein and control of the systems that produce it as well as an understanding of the accuracy and precision of the assays used for testing. Harmonization of specifications among the worldwide regulatory authorities is critical for the future development of new pharmaceuticals. A continuing dialogue between industry and regulators to achieve this goal needs to be encouraged and supported.

    2009-01-01

    The present study was conducted to characterize several raw materials and co-products from the titanium dioxide industry in relation to their elemental composition (major, minor and trace elements), granulometry, mineralogy, microscopic morphology and physical composition. The main objective was to gain basic information for the future potential application of these co-products in fields such as agriculture, construction, civil engineering, etc. Microscopic studies were performed by applying scanning electron microscopy with X-ray microanalysis (SEM-XRMA) while the mineralogical compositions were analysed by means of the X-ray diffraction (XRD) technique. The concentrations of major elements such as Na, Al, Si, Ca, Ti, Fe, S and K were determined by X-ray fluorescence (XRF), while heavy metals and other trace elements were determined by ICP-MS. The physicochemical characterization of the raw materials used in the titanium dioxide industry, in addition to the characterization of the co-products generated, has enabled the evaluation of the degree of fractionation of different elements and compounds between the different co-products, as well as the control of the possible variations in the physicochemical composition of the raw materials throughout the time and the study of the influence of these variations in the characteristics of the obtained co-products. As a main conclusion of our study, it is possible to indicate that the levels of the pollutant elements associated to the co-products analysed were, in general, within safe limits and, therefore, they could potentially be used in composites as fertilizers or for building materials in road construction, etc. Nevertheless, for the specific application of each of these co-products in agriculture, construction and civil engineering, additional studies need to be performed to evaluate their appropriateness for the proposed application, together with specific studies on their health and environmental impact.

    Wimmer, E.

    2008-02-01

    A workshop, 'Theory Meets Industry', was held on 12-14 June 2007 in Vienna, Austria, attended by a well balanced number of academic and industrial scientists from America, Europe, and Japan. The focus was on advances in ab initio solid state calculations and their practical use in industry. The theoretical papers addressed three dominant themes, namely (i) more accurate total energies and electronic excitations, (ii) more complex systems, and (iii) more diverse and accurate materials properties. Hybrid functionals give some improvements in energies, but encounter difficulties for metallic systems. Quantum Monte Carlo methods are progressing, but no clear breakthrough is on the horizon. Progress in order-N methods is steady, as is the case for efficient methods for exploring complex energy hypersurfaces and large numbers of structural configurations. The industrial applications were dominated by materials issues in energy conversion systems, the quest for hydrogen storage materials, improvements of electronic and optical properties of microelectronic and display materials, and the simulation of reactions on heterogeneous catalysts. The workshop is a clear testimony that ab initio computations have become an industrial practice with increasingly recognized impact.

    The United States currently does not have formal design criteria for qualifying ductile cast iron (DCI) transportation casks. There is also no dedicated material standard for DCI for this particular application. A draft ASTM material specification has been written and is currently in the ASTM approval process. This paper reviews the brief history of the development of the specification, the technical basis for the material properties, the ASTM approval process and the current status of the draft specification. The expected implications of having an adopted ASTM specification on the licensing process are also discussed. (orig./DG)

    Neodymium, dysprosium, tellurium, indium and gallium are materials whose shortage and price fluctuations could have an impact on the development of wind energy and solar energy as about a quarter of the production of rare earth elements is used for the fabrication of permanent magnets. Between 1966 and 1984 the United States were the first producer in the world, then the production of these materials has moved little by little towards China. In 2010 China produced 97% of rare earth elements and in the same year it reduced the quantities to export which led to a panic in the market. Now governments and the industry are facing the challenge. New production capacities have been opened particularly in the United-States and Australia, ancient mines have been re-opened, recycling policies have been developed and an optimization of the use of rare-earth elements has been favored.

    One of the main directions of technology development in the 21st century is the development and application of new materials, and the key to the development of the new material industry lies in the industrial technology innovation. The gross scale of the new material industry in Hunan Province ranks the first array in China. Based on the present situation of Hunan’s new material industry, three modes of technology innovation alliance are put forward in this paper, namely the government-driven mode, the research-driven and the market-oriented mode. The government-driven mode is applicable to the major technology innovation fields with uncertain market prospect, high risk of innovation and government’s direct or indirect intervention;the research-driven mode is applicable to the key technology innovation fields with a high technology content; and the market-oriented mode is applicable to the general innovation fields in which enterprises have demands for technology innovation but such innovation must be achieved via cooperative research and development.

    Analytical performance specifications are crucial in test development and quality control. Although consensus has been reached on the use of biological variation to derive these specifications, no consensus has been reached which model should be preferred. The Six Sigma concept is widely applied in industry for quality specifications of products and can well be compared with Six Sigma models in clinical chemistry. However, the models for measurement specifications differ considerably between both fields: where the sigma metric is used in clinical chemistry, in industry the Number of Distinct Categories is used instead. In this study the models in both fields are compared and discussed. Copyright © 2018. Published by Elsevier Inc.

    2018-01-01

    Full Text Available The generation of enormous volumes of mine-tailing waste is standard practice in the mining industry. Large quantities of these tailings are also sources of kaolinite-rich materials that accumulate in slag heaps, causing significant environmental degradation and visual impacts on the landscape. The consequences of coal refuse dumped in slagheaps calls for the study of eco-innovative solutions and the assessment of waste types. Moreover, the environmental benefits of reusing large amounts of contaminated waste are also evident. Hence, the objective of this investigation is to expand current knowledge of new siliceous-aluminium minerals and their pozzolanic activity. Four raw tailing samples are characterized to determine their chemical (by ICP/MS analysis, morphological (by SEM/EDX analysis, and mineralogical (by XRD analysis compositions prior to their thermal activation that transforms the inert wastes at various temperatures into materials with cementitious properties. The results of XRD analysis following activation confirmed that the kaolinite content is fully transformed into metakaolinite. The coal refuse samples presented sufficiently reliable levels of pozzolanic activity for use as additives in industrial cements.

    The liquidation of waste dumps on the surface of mining enterprises and realization of measures by environment protection of air and aquatic basins are connected to the complex processing of mining mass. The main directions of utilization of mining rocks and coal wastes realized in Ukraine industry are: - filling of mines worked-out area by grouting solutions; - ceramic brick, porous filling materials and binding materials production; - road-making, construction of hydrostructures and industrial objects; - output of concrete items predominantly for using in mining conditions. The peculiarity of wastes using in above-mentioned fields is the possibility of their mass application in quantities commensurable with valumes of their yields. The experience of enterprises work which process mining rocks into building materials by burning method (ceramic brick, porous aggregates of concretes as aggloporite, expanded clay aggregate) has shown that unconstant and, as the rule, exceeding norms content of carbon and sulphur in the rock results to deterioration of products quality and technological factors of production. Unstability of carbon content in raw material makes the burning process hardly operated. Obtained products having residual carbon in the view of coke residue are often characterized by lower physical-mechanical characteristics. (orig./SR)

    2007-01-01

    Iodine sulfur (IS) process is one of the promising processes for a hydrogen production by using a high temperature heat generated by a very high temperature gas cooled reactor(VHTR) in the nuclear power industries. Even though the IS process is very efficient for a hydrogen production and it is not accompanied by a carbon dioxide evolution, the highly corrosive environment of the process limits its application in the industry. Corrosion tests of selected materials were performed in sulfuric acid to select appropriate materials compatible with the IS process. The materials used in this work were Fe-Cr alloys, Fe-Ni-Cr alloys, Fe-Si alloys, Ni base alloys, Ta, Ti, Zr, SiC, Fe-Si, etc. The test environments were 50 wt% sulfuric acid at 120 .deg. C and 98 wt% at 320 .deg. C. Corrosion rates were measured by using a weight change after an immersion. The surface morphologies and cross sectional areas of the corroded materials were examined by using SEM equipped with EDS. Corrosion behaviors of the materials were discussed in terms of the chemical composition of the materials, a weight loss, the corrosion morphology, the precipitates in the microstructure and the surface layer composition

    Full Text Available Lignin is present in plant cell secondary wall, associated to carbohydrates preventing their efficient hydrolysis, and cellulose pulp manufacture basically consists in breaking down the middle lamella of plant cells, individualizing fibers such as cellulose from the other biopolymers. Different levels of lignocellulose are found in plant residues and they can be decomposed by extracellular fungal lignin modifying enzymes, used as a tool to reduce waste materials in contaminated soils and effluents. In the paper mill industries, for instance, they are a suitable or complementary alternative to the traditional methods of pulping/bleaching, contributing to improve paper strength as well as to reduce the pitch content, the quantity of chemicals and the consume of electrical energy. The aim of this review was to describe the fungal degradation of lignocellulosic like-material, the non-specific enzymatic aspects of the attack of wood and agricultural wastes, the fungal ability for biosorption and bioconversion, and its applications in the pulp/paper industry and bioremediation.

    High-strength, cold-formable steels offer great potential for meeting cost and safety requirements in the automotive industry. In view of strengths of up to 1200 MPa now attainable, certain aspects need to be analysed and evaluated in advance in the development process using these materials. In addition to early assessment of crash properties, it is also highly important to adapt the forming process to match the material potential. The steel making companies have widened their portfolios of cold-rolled dual-phase steels well beyond the conventional high-strength steels. There are added new grades which offer a customized selection of high energy absorption, deformation resistance or enhanced cold-forming properties. In this article the necessary components for material modelling for finite element simulation are discussed. Additionally the required tests for material model calibration are presented and the potentials of the thyssenkrupp Steel material data base are introduced. Besides classical tensile tests at different angles to rolling direction and the forming limit curve, the hydraulic bulge test is now available for a wide range of modern steel grades. Using the conventional DP-K®60/98 and the DP-K®700Y980T with higher yield strength the method for calibrating yield locus, hardening and formability is given. With reference to the examples of an A-pillar reinforcement and different crash tests the procedure is shown how the customer can evaluate an optimal steel grade for specific requirements. Although the investigated materials have different yield strengths, no large differences in the forming process between the two steel grades can be found. However some advantages of the high-yield grade can be detected in crash performance depending on the specific boundary and loading conditions.

    The are some industrial activities in which radioactive sources are used as a tool for industrial gauging gammagraphy or density and moisture testing of soils. There are others in which radioactive materials are present in a collateral way, as in the NORM industry in which there are naturally occurring radioactive materials such as starting materials, sub product or waste. Finally, radioactive materials or sources may be present in the industry accidentally such as in the case of scrap metals processing industries or in other industries in which orphan sources may be present as a consequence of activities carried out in the past. The UTPR can provide technically qualified personnel for specific assessment in radiation protection to all of these industrial installations together with the adequate means to carry out operations with radioactive sources in both a safe and correct way.

    The rupture and damaging of materials and structures is almost always and unwanted events which may have catastrophic consequences. Even if the mechanical failure causes can often be analyzed using a thorough knowledge of materials behaviour, the forecasting and prevention of failures remain difficult. While the macroscopic mechanical behaviour is often the result of average effects at the structure or microstructure scale, the damage is very often the result of the combination of load peaks, of localization effects and of microstructure defects. This book, presented in two volumes, takes stock of the state-of-the-art of the knowledge gained in the understanding and modelling of rupture and damaging phenomena of materials and structure, mostly of metallic type. It gives an outline of the available knowledge for other classes of materials (ceramics, biomaterials, geo-materials..) and for different types of applications (aeronautics, nuclear industry). Finally, it examines the delicate problem, but very important in practice, of the behaviour of assemblies. Content: Vol.1 - physical mechanisms of materials damaging and rupture; rupture mechanics; cyclic plasticity and fatigue crack growth; fatigue crack propagation; environment-induced cracking; contacts and surfaces. Vol.2 - glasses and ceramics; natural environments: soils and rocks; mechanical behaviour of biological solid materials: the human bone; contribution of simulation to the understanding of rupture mechanisms; assemblies damaging and rupture; industrial cases (behaviour of PWR pressure vessel steels, and thermal and mechanical stresses in turbojet engines).

    Chaffin, D B

    1979-01-01

    It is reported from various sources that overexertion due to lifting, pushing, pulling, and carrying objects accounts for about 27 percent of all compensable industrial injury and illness in the United States. Resulting strain/sprain injuries account for over 50 percent of workmen's compensation clams in many industries. Almont two-thirds of these involve back pain, with reported compensation and medical payments totaling well over one billion dollars annually in the U.S. An estimated 300,000 plus workers will be affected each year, 5 to 10 percent of whom will have a permanent disability and often will be unemployable. This paper attempts to describe four basic approaches used to study this occupational health problem. In so doing, a concerted effort is made to identifiy the gaps in knowledge which need to be more fully researched. The approaches utilized to understand and control the hazards of manual materials handling are: 1) epidemiological studies of job and worker attributes to identify those that individually and in combination cause musculoskeletal incidents, 2) psychophysical studies to ascertain the volitional tolerance of workers to the stress mitigated by manual materials-handling activities, 3) biomechanical studies of the musculoskeletal system during common exertions required in manual materials-handling activities, and 4) physiological studies of the strain imposed on the cardiovascular system during repeated load-handling activities. The state of knowledge from each of these approaches is summarized briefly, and a case is made that much research is still needed to substantiate the necessary controls to lessen the economic burden and human suffering associated with manual materials-handling acts in industry.

    The composites appear as an extremely favorable alternative for different industries, due to the fact that it combines the best mechanical properties with the best physic-chemical properties of two or more materials. Nowadays, in the evaluation of materials, besides criteria such as economic viability and performance, the environmental criterion was included in this evaluation. Part of the environmental criteria is the use of biodegradable materials and/or recycled materials. In this sense, researches focused on vegetal fibers, as reinforcement in composites are growing considerably and positive results for its performance were achieved. Moreover, the environmental-friendly approach not only is the unique advantage on usage of vegetal fibers, but also it has an economical advantage, because of the low cost and good performance due to low density. The fiber extracted from the pineapple leaf (PALF) is a new alternative for automotive industry as cellulose-based fiber composite. In this sense, the present paper aims to present the characterization of the pineapple leaf fiber for manufacturing the automotive composite materials. Milled pineapple fibers extracted, in two different ways and submitted to mercerisation treatments, were characterized by mechanical and thermal properties; density; morphology; FTIR spectroscopy, EDX and X-ray diffraction. It is important to characterize the fibers, in order to obtain appropriate mechanical properties of composite. (author)

    The industrial specification for production of the G-10CR grade of cryogenic high-pressure laminate has been revised and accepted by US manufacturers. The objective was to make the specification as generic as possible without adversely affecting performance and to add a material performance criteria to the specification. G-10CR and G-11CR products have been produced by five US industrial laminating forms. No significant differences in cryogenic mechanical properties were found among G-10CR material produced by these manufacturers. This indicates that the specifications are fulfilling their intended purpose. An efficient system for producing research materials for systematic screening of the parameters influencing cryogenic radiation resistance was devised. Laboratories in Japan and England have agreed to actively cooperate with NBS in further development of this system

    Full Text Available In this study, a polymer, prepared by crosslinking cyclodextrin (CD by means of a polycarboxylic acid, was used for the removal of pollutants from spiked solutions and discharge waters from the surface treatment industry. In spiked solutions containing five metals, sixteen polycyclic aromatic hydrocarbons (PAH and three alkylphenols (AP, the material exhibited high adsorption capacities: >99% of Co2+, Ni2+ and Zn2+ were removed, between 65 and 82% of the PAHs, as well as 69 to 90% of the APs. Due to the structure of the polymer and its specific characteristics, such as the presence of carboxylic groups and CD cavities, the adsorption mechanism involves four main interactions: ion exchange, electrostatic interactions and precipitation for metal removal, and inclusion complexes for organics removal. In industrial discharge waters, competition effects appeared, especially because of the presence of calcium at high concentrations, which competed with other pollutants for the adsorption sites of the adsorbent.

  17. Reprocessing of metallurgical slag into materials for the building industry

    Pioro, L.S.; Pioro, I.L.

    2004-01-01

    Several methods of reprocessing metallurgical (blast furnace) slag into materials for the building industry, based on melting aggregates with submerged combustion, were developed and tested. The first method involves melting hot slag with some additives directly in a slag ladle with a submerged gas-air burner, with the objective of producing stabilized slag or glass-ceramic. The second method involves direct draining of melted slag from a ladle into the slag receiver, with subsequent control of the slag draining into the converter where special charging materials are added to the melt, with the objective of producing glass-ceramic. A third method involves melting cold slag with some additives inside a melting converter with submerged gas-air burners, with the objective of producing glass-ceramic fillers for use in road construction. Specific to the melting process is the use of a gas-air mixture with direct combustion inside the melt. This feature provides melt bubbling to help achieve maximum heat transfer from combustion products to the melt, improve mixing (and therefore homogeneity of the melt), and increases the rate of chemical reactions. The experimental data for different aspects of the proposed methods are presented. The reprocessed blast-furnace slag in the form of granules can be used as fillers for concretes, asphalts, and as additives in the production of cement, bricks and other building materials. As well, reprocessed blast-furnace slag can be poured into forms for the production of glass-ceramic tiles

  19. Society, materiality, resilience and sustainability: inquiries from the fields of industrial waste management, urban climate science and eco-urbanism

    Science.gov (United States)

    MacKillop, Fionn

    2018-06-01

    This paper aims to investigate the links between materiality and society at a conceptual level, using examples from the author's decade of research in several fields relevant to the issue. With current talk of the need for `sustainability' and `resilience' reaching fever pitch in industry, politics and other arenas, there is a regrettable tendency to muddle the meaning of these words. Drawing on original research carried out in the UK, China, Germany, and Australia, and using the conceptual approaches of actor-network theory (ANT) and urban political ecology (UPE), the author invites us to re-engage with the materiality of society and how we, as businesses, consumers and thinkers, can advance sustainability and resilience through this re-engagement. We will ask what sustainability and resilience mean, for whom and in what context. We will also look at how we can shift thinking and reinvigorate these words, by contributing to the dialogue between the social sciences and business and industry. Specific examples will be taken from the UK and Chinese steel industries; climate-sensitive urban design in Manchester and Stuttgart; and housing construction and affordability in Scotland and Australia, thus covering a wide range of issues related to urban sustainability and resilience in relation to materiality.

    Author.Field, laboratory and market studies are a must for proper evaluation of natural resources for the mineral industry of lebanon. Sites selectively convenient to the existing major Lebanese ceramics industry centered in the Beqa'a region, were investigated as to their geology, geography and economic character. The raw materials are shales, mud stones, siltstones and other argillaceous rocks of Jurassic to Cretaceous age coming from selective sites in south and central Lebanon. The finished products include wall, floor, roofing tiles, pipes, sanitary ware, pottery and brick specimens. Differential thermal analysis, scanning electron microscopy, firing and physico-chemical tests and analyses characterized the raw materials into two major groups: the suitable are siliceous argillaceous rocks and unsuitable calcareous argillaceous rocks. The suitable group is divided into two varieties. The first is dominantly a disordered Kaolinite with low drying and firing values, low plasticity index, giving a gray firing color, and with low iron and soluble salts content. The second is dominantly illite with the above properties showing medium values, and giving a red color due to the iron content. The unsuitable group is dominantly an intermixed clay type with high plasticity, soluble salts content and shrinkage values. The exposed parts, of the studied 11 sites the proved suitable, have estimated reserves around 23000 m 3 . This is only a fraction of the resources available to meet industrial consumption requirements. Further area coverage investigation and drilling would prove the very high potential existing for the industry. These Lebanese materials as determined by their properties, are used partially or fully in the various products. The foreign import, notably from non-Arab sources can be substituted by nearby economic Arab deposits. The ceramics industry is faced with developmental problems, economic, social and technical.

    1999-01-01

    Naturally Occurring Radioactive Materials (NORM) have been known to be present in varying concentrations in hydrocarbon reservoirs. These NORM under certain reservoir conditions can reach hazardous contamination levels.the recognition of NORM as a potential source of contamination to oil and gas facilities has become widely spread and gained increased momentum from the industry. Some contamination levels may be sufficiently severe that maintenance and other personnel may be sufficiently severe that maintenance and other personnel may be exposed to hazardous concentrations. Health and environmental concerns regarding NORM have become an important safety issue in upstream petroleum industry in Egypt since the early 1990's when NORM have been detected in different gas and oil production facilities. In these facilities, radiation protection measures were taken to realize safe handling and disposal of NORM according to the applicable international standards. This paper describes the extent of the NORM contamination problem in Egypt and presents guidelines for dealing with NORM based on the latest scientific techniques and international experiences

    The Galicia industrial activities request a big amount of raw materials energy and water, generating several kinds of residues. Most of them directly spoil the environment, causing important damages. Furthermore, the primary energy self supply capacity doesn't exist at this moment, being substituted by high levels of energetic resources importations satisfying industrial demand without decreasing the electricity and petroleum products exportations. This article tries to develop a complete analysis of this kind of problems, making an approach to the environmental situation of the Galicia manufacturing industry through materials, energy and water flow models. It focuses in those sectors which have a remarkable production within the Galicia industry, analysing their situation in two different years, 1992 and 2000. This will allow to identify possible tendencies of the industry as a whole, like a relative dematerialization, followed by a complete rematerialization.

    Oil and gas industry in the Great Jamahiriya is one of those industries that were accompanied with generation of some solid and liquid waste, which associated with risks that might lead to harmful effects to the man and the environment. Among those risks the continuous increase of radioactivity levels above natural radioactive background around operating oil fields, due to accumulation of solid and liquid radioactive scales and sludge as well as contaminated produced water that contain some naturally occurring radioactive materials ( NORM/TE-NORM). Emergence of NORM/TE-NORM in studied area noticed when the natural background radioactivity levels increased around some oil fields during end of 1998, For this study, six field trips and a radiation surveys were conducted within selected oil fields that managed and owned by six operating companies under NOC, in order to determine the effective radiation dose in contrast with dose limits set by International Counsel of Radiation Protection(ICRP),and International Atomic Energy Agency(IAEA) Additionally solid samples in a form of scales and liquid samples were also taken for further investigation and laboratory analysis. Results were tabulated and discussed within the text .However to be more specific results pointed out to the fact that existence of NORM/TE-NORM as 226 Ra, 228 Ra, within some scale samples from surface equipment in some oil and gas fields in Jamahiriya were significant. As a result of that, the workers might receive moderate radiation dose less than the limits set by ICRP,IAEA, and other parts of the world producing oil and gas. Results predicted that within the investigated oil fields if workers receive proper training about handling of NORM/TE-NORM and follow the operating procedure of clean ups, work over and maintenance plane carefully, their committed exposure from NORM/TE-NORM will be less than the set limits by ICRP and IAEA. In a trend to estimate internal radiation dose as a result of possible

    The early sixties witnessed the beginning of Electron Beam (EB) processing of materials using high-energy electrons and has emerged as a well established technology, presently being adapted by the industry. The process and the processed materials showed definite and distinct advantages/characteristics over the available conventional methods. Even though the commercial exploitation started initially in polymer modifications for better (and suitable) performance through polymerization, cross-linking, degradation and grafting, the processing fields are now diverged to sterilization of health care, food irradiation, controlled defects in semiconductor devices and semi and/or precious stones, waste water/flue gas treatment etc. The availability of electron accelerators that operate as per the requirement of the industrial needs, easy maintenance, expertise availability etc brought the EB processing industry into a multi dollar business world wide. In USA and Japan there are more than 1200 accelerators currently operative in automobile tire, wire and cable and heat shrinkable industry. Output beam powers exceeding 400 kW with electron energy ranging from few hundred keV up to 10 MeV are made available to the industry. In BARC EB processing started with the 2MeV/20 kW electron accelerator and suitable processing techniques have been developed for applications like polymer cross linking (heat resistant LDPE O-rings, wire and cable insulation), color enhancement in precious stones (diamonds) on industrial scale and polymer curing, grafting, degradation on R and D/pilot scale. The commercial success of the process enabled the private cable industry to set up accelerators at their factories. On research and development front, the accelerator is being utilized to develop new polymer blends for high temperature applications, for solid and liquid waste treatment, polypropylene grafting experiments for uranium extraction from sea water, surface curing etc. This paper gives

    The Conducting Polymer project funded by the AIM Materials Program is developing new methods for the synthesis of electronically conducting polymers and is evaluating new industrial applications for these materials which will result in significant reductions in energy usage or industrial waste. The applications specifically addressed during FY 1994 are electrochemical capacitors and membranes for gas separation. As an active material in electrochemical capacitors, conducting polymers have the potential of storing large amounts of electrical energy in low cost materials. Such devices are needed in electronics for power failure back-up and peak power, in power supplies for filtering, and in electric vehicles for peak power and load leveling. As a gas electrically adapt the membrane for specific gas combinations. Potential energy savings in the US. for this application are estimated at 1 to 3 quads/yr.

    The importance of having suitable and well characterized non-destructive assay (NDA) reference materials for the verification activities of the safeguards control authorities is stressed. The Euratom Inspectorate and the IAEA have initiated an extensive programme for the procurement and preparation of Joint Euratom/IAEA safeguards NDA reference materials with the active participation of the Ispra Establishment of the Euratom Joint Research Centre. The different type and nature of materials, condition of measurements, and plant characteristics and provisions had to be taken into account for plant-specific NDA reference materials. The preparation of each reference material was planned case by case and specific criteria such as limitations in different facilities, measurement capabilities, conditions, product availability and population variability are being ascertained. A procurement scheme was prepared describing step-by-step procedures detailing responsibilities, measurement conditions, destructive analysis schemes, desired characteristics and methods of data evaluation. This paper describes the principles and procedures carried out for the preparation of a reference MOX pin, low enriched uranium reference rods, low enriched uranium reference drums, reference MTR assemblies, and THTR reference pebbles. The scheme for each characterization technique is presented. (author)

    1996-01-01

    During the sixties, governments have installed hot nuclear materials research facilities to characterize highly radioactive materials, to describe their in-pile behaviour, to develop and test new reactor core components, and to provide the industry with radioisotopes. Since then, the attitude towards the nuclear option has drastically changed and resources have become very tight. Within the changed political environment, the national research centres have defined new objectives. Given budgetary constraints, nuclear facilities have to co-operate internationally and to look for third party research assignments. The paper discusses the problems and needs within experimental nuclear research facilities as well as industrial requirements. Special emphasis is on cultural topics (definition of the scope of nuclear research facilities, the search for competitive advantages, and operational requirements), social aspects (overageing of personnel, recruitment, and training of new staff), safety related administrative and technical issues, and research needs for expertise and state of the art analytical infrastructure

  18. The Methodical Aspects of Material Stimulation in the Motivation System at Enterprises of Electricity Industry

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available The article improves the methodical aspects of estimating material stimulation at enterprises of electricity industry. It has been determined that the provided taxonomy coefficients synthetically characterize changes in the values of attributes of the groups studied. Their most important advantage is that, in the course of analysis, we can now use only one indicator, which characterizes the direction and scope of changes in the processes described by the set of arbitrary numbers of incoming attributes. The level of material stimulation in the motivation system of enterprises of electricity in 2012–2015 was researched. It has been noted that during the outlined period there has been a general trend towards an increase in the integral indicator. This results from the economic crisis occurrences and the lack of a well-functioning organizational and economic mechanism for managing the motivation system at enterprises of this industry branch. The integrated assessment of enterprises extends the economic essence of the concept of material stimulation in the motivation system at enterprises of electricity industry, allowing it to be used to characterize the enterprise’s ability to return to its equilibrium status, preserve the parameters and move to a new stage of development in the conditions of accidental changes in the external and internal environment.

    This paper focuses on state-of-the-art materials recovery techniques employed in the solidification/stabilization of industrial wastes. Particular consideration is given to the Italian situation. After a review, with reference to waste/matrix compatibility inherent problems, of the presently employed main encapsulation techniques (with matrices based on cement, lime, clay, thermoplastic materials, organic polymers, macroencapsulating compounds), attention is addressed to solidification systems which allow a recovery of the waste material as low-technology by-products. Regarding the most important industrial waste streams: thermoplastic refuse, incinerator ashes, chemical sludges, the paper reviews efforts devoted not only to their chemical fixation in order to fulfill the current land disposal requirements, but mainly to their employment for production of manufactured articles.

    Designing bulk material handling equipment requires a thorough understanding of the mechanical behaviour of powders and grains. Experimental characterization of granular materials is introduced focusing on flowability. A new prototype is presented which performs granular column collapse tests. The device consists of a channel whose design accounts for test inspection using visualization techniques and load measurements. A reservoir is attached where packing state of the granular material can be adjusted before run-off to simulate actual handling conditions by fluidisation and deaeration of the pile. Bulk materials on the market, with a wide range of particle sizes, can be tested with the prototype and the results used for classification in terms of flowability to improve industrial equipment selection processes.

  1. Specification of merger gains in the Norwegian electricity distribution industry

    International Nuclear Information System (INIS)

    Saastamoinen, Antti; Bjørndal, Endre; Bjørndal, Mette

    2017-01-01

    Electricity distribution often exhibits economies of scale. In Norway, a number of smaller distribution system operators exist and thus there is potential to restructure the industry, possibly through mergers. However, the revenue cap regulatory model in Norway does not incentivize firms to merge as merging leads to a stricter revenue cap for the merged company. Thus the regulator compensates the firms in order to create such incentives. The amount of compensation is based on the potential gains of the merger estimated using a data envelopment analysis (DEA) based frontier approach introduced by Bogetoft and Wang (2005). DEA is however only one of many possible frontier estimators that can be used in estimation. Furthermore, the returns to scale assumption, the operating environment of firms and the presence of stochastic noise and outlier observations are all known to affect to the estimation of production technology. In this paper we explore how varying assumptions under two alternative frontier estimators shape the distribution of merger gains within the Norwegian distribution industry. Our results reveal that the restructuring policies of the industry may be significantly altered depending how potential gains from the mergers are estimated. - Highlights: • The merger gains of Norwegian electricity distribution firm are investigated. • Different estimators and model specifications are applied. • Results show that the gains are significantly affected by the model choice. • Incentives to merge may be shaped through the estimation of gains.

    X-ray radiography and gamma radiography are used in industrial radiography. X-rays and gamma rays have the ability to penetrate materials and be absorbed by different densities. This characteristic makes them useful tools in industrial and medical radiography. The sources used for the generation of x-rays, gamma rays and radioisotopes are discussed. Films are one of the recording methods of x-radiography. The article also deals with advantages and disadvantages of radiography. Factors governing radiation exposure includes: the type of radiation source, material to be radiographed, distance, film, and the method for development. International specifications are also responsible for strict control over the standard of workmanship in industrial radiography

    To promote the recycling of industrial waste and to develop value-added products using these resources, the possibility of manufacturing glass-ceramic materials of SiO2-CaO-Al2O3 system has been investigated by various heat treatment processes. Glass-ceramic materials with six different chemical compositions were prepared using steel industry slags and power plant waste by melting, casting and heat treatment. The X-ray diffraction results indicated that diopside and anorthite were the primary phases in the samples. The anorthite phase was formed in SiO2-rich material (at least 43 wt%). In CaO-rich material, the gehlenite phase was formed. By the differential scanning calorimetry analyses, it was found that the glass transition point was in the range of 973-1023 K, and the crystallization temperature was in the range of 1123-1223 K. The crystallization temperature increased as the content of Fe2O3 decreased. By the multi-step heat treatment process, the formation of the anorthite phase was enhanced. Using FactSage, the ratio of various phases was calculated as a function of temperature. The viscosities and the latent heats for the samples with various compositions were also calculated by FactSage. The optimal compositions for glass-ceramics materials were discussed in terms of their compressive strength, and micro-hardness.

    Friction stir welding (FSW) is an emerging technology for joining flat and thin metal materials and has been applied in manufacturing in aviation and automotive industries. Fatigue property is one of the most important items to be evaluated for the structural integrity of the products, and therefore, it is necessary to visualize the three-dimensional (3D) behavior of fatigue cracks propagating in the non-homogeneous and anisotropic stirred zone of FSW joints. We have applied laminography with synchrotron radiation of SPring-8 to the FSW joints of aluminum alloy as a typical structural material. The results showed that the fatigue cracks propagated in a unique way depending on the stirred material. (author)

    Consumers Power Company's (CPCo) Palisades plant is in the process of converting from custom technical specifications to the new industry standard, Restructured Standard Technical Specifications (RSTS). Custom technical specifications were the precursor to standard technical specifications, being issued to plants built prior to 1972. In May 1989, each of the four light water reactor owners' groups completed topical reports presenting their version of Restructured Standard Technical Specifications to the Nuclear Regulatory Commission (NRC). After approval of the owners' groups versions of the RSTs by the NRC, individual operating reactors will begin to make the conversion to the RSTS. Each owners' group has designated a lead plant, which will be the first of that vendor type to convert. All of the lead plants currently operate under standard technical specifications. The content of the RSTS was determined by comparing the standard technical specifications with selection criteria specified in the Commissions Interim Policy Statement

    This study presents the findings of radiometric analysis carried out to determine the activity concentrations of natural radionuclides in raw materials (clay, kaolin, quartz, feldspar, dolomite, alumina, bauxite, zirconium minerals, red mud and frit) and end products (glazed ceramic wall and floor tiles) in the Turkish ceramics industry. Hundred forty-six samples were obtained from various manufacturers and suppliers throughout the country and analyzed using gamma-ray spectrometer with HPGe detectors. Radiological parameters such as radium equivalent activity, activity concentration index and alpha index were calculated to assess the radiological aspects of the use of the ceramic end products as decorative or covering materials in construction sector. Results obtained were examined in the light of the relevant national and international legislation and guidance and compared with the results of similar studies reported in different countries. The results suggest that the use of ceramic end product samples examined in the construction of dwellings, workplaces and industrial buildings in Turkey is unlikely to give rise to any significant radiation exposure to the occupants.

    2009-09-01

    Mineral Resources are very essential for industrialization and hence facilitating socioeconomic developments. Resources like coal, iron ore, Bauxite, chromite, limestone, ilmenite and many other ores and minerals are the raw materials for development of various thermal, metallurgical, chemical and refractory industries. The mineral resources are being harnessed from their respective mines and the mining industries have expanded rapidly to meet their growing demands of various 'mineral based industries. The energy and reductants required for these industries are met from both - coking and non coking coal. Nearly 70% of the energy requirement of India is met from coal. In recent years, with the increasing demand of metals, alloys, refractories and thermal energy, most of the high-grade ores and minerals have been consumed. Unfortunately most of the low grade ores and minerals are left at the mine sites as wastes. As a matter of fact, these low grade ores are much larger in quantities compared to the high grade ones. Therefore, it has been essential to mine and beneficiate the low grade ores which can be suitably-utilized in the respective industries. It has also been necessary to develop more efficient technology to utilize these raw materials more effectively producing minimum amount of wastes and also conserving the energy resources as far as possible. Time has come to develop environment friendly most suitable technology to utilize all types of low grade and complex ores and minerals in order to meet the requirements of rapidly expanding mineral based industries of India. Unless effective programmes are made in this regard and implement those in time, India is bound to face a disastrous situation both in industrial and economic sectors. The conference is organised keeping these in view to take a stock of new and economically viable processes for mining and beneficiating low and complex ores and minerals and utilizing these judiciously in the industries.

    The control of the corrosion phenomenon is of prime importance for the nuclear industry. The efficiency and the safety of facilities can be affected by this phenomenon. The nuclear industry has to face corrosion for a large variety of materials submitted to various environments. Metallic corrosion operates in the hot and aqueous environment of water reactors which represent the most common reactor type in the world. Progresses made in the control of the corrosion of the different components of these reactors allow to improve their safety. Corrosion is present in the facilities of the back-end of the fuel cycle as well (corrosion in acid environment in fuel reprocessing plants, corrosion of waste containers in disposal and storage facilities, etc). The future nuclear systems will widen even more the range of materials to be studied and the situations in which they will be placed (corrosion by liquid metals or by helium impurities). Very often, corrosion looks like a patchwork of particular cases in its description. The encountered corrosion problems and their study are presented in this book according to chapters representing the main sectors of the nuclear industry and classified with respect to their phenomenology. This monograph illustrates the researches in progress and presents some results of particular importance obtained recently. Content: 1 - Introduction: context, stakes and goals; definition of corrosion; a complex science; corrosion in the nuclear industry; 2 - corrosion in water reactors - phenomenology, mechanisms, remedies: A - uniform corrosion: mechanisms, uniform corrosion of fuel cladding, in-situ measurement of generalized corrosion rate by electrochemical methods, uniform corrosion of nickel alloys, characterization of the passive layer and growth mechanisms, the PACTOLE code - an integrating tool, influence of water chemistry on corrosion and contamination, radiolysis impact on uniform corrosion; B - stress corrosion: stress corrosion cracking

    Waste is classified (art.184, sub. 1, L.D. n.152/2006) as urban or special depending on its origin and whether it is dangerous or not, as well as the degree of danger. The reuse and recycling of materials are two of the main features that characterize the concept of the circular economy. Every firm operating in the field of the circular economy should adopt an industrial approach based on resource efficiency and the use and supply of sustainable raw materials, which can be achieved through innovative technologies, innovative methodologies and new business models. GE.S.P.I, has become a leading firm in the sector of hazardous industrial waste disposal, adding value to waste through a groundbreaking technology. The result of the process is the production of energy, as well as the creation of ash; this ash is then treated in order to separate dangerous heavy metals from the ash through the technique of eddy currents. Metals and purified ash are then put on the market. The aim of this paper is the price definition of this special waste thanks to the analysis of the specific second raw materials market. In this firm, incineration is a process where emissions are strongly controlled by innovative instruments in order to excel in the social and environmental respect. Through SWOT analysis we moreover describe how a company can turn the weaknesses of a high risk area into opportunities and value becomes a useful problem solving instrument to analyze logistic, marketing, and social responsibility, in the perspective of the optimization of eco-management material flows.

    Industrial eggshell (ES) is an animal by-product (ABP) involving some risk if not properly managed. Composting is a possible treatment approved for its safe use. This study aims to assess the influence of using N-rich material (grass clippings (GC)) to improve co-composting of ES mixtures for reaching sanitizing temperatures imposed by the ABP regulation from the European Union. Two sets of mixtures (M1 and M2) were investigated, each containing industrial potato peel waste, GC and rice husks at 3:1.9:1 and 3:0:1 ratios by wet weight. In each set, ES composition ranged from 0% to 30% (w/w). Co-composting trials were performed in self-heating reactors for 25 days, followed by maturation in piles. Results showed that only M1 trials attained temperatures higher than 70°C for nine consecutive hours, but N-losses by stripping on average were four- to five-fold higher than M2. In the absence of N-rich material, biodegradability of mixtures was 'low' to 'moderate' and organic matter conversion was impaired. Physical, chemical and phytotoxic properties of finished composts were suitable for soil improvement, but M1 took 54 more days to achieve maturity. In conclusion, co-composting ES with N-rich materials is important to assure the fulfilment of sanitizing requirements, avoiding any additional thermal treatment.

    It is necessary to assess radiation dose to workers due to inhalation of airborne particulates containing naturally occurring radioactive materials (NORM) to ensure radiological safety required by the Natural Radiation Safety Management Act. The objective of this study is to develop an internal dose assessment procedure for workers at industries using raw materials containing natural radionuclides. The dose assessment procedure was developed based on harmonization, accuracy, and proportionality. The procedure includes determination of dose assessment necessity, preliminary dose estimation, airborne particulate sampling and characterization, and detailed assessment of radiation dose. The developed dose assessment procedure is as follows. Radioactivity concentration criteria to determine dose assessment necessity are 10 Bq·g-1 for 40K and 1 Bq·g-1 for the other natural radionuclides. The preliminary dose estimation is performed using annual limit on intake (ALI). The estimated doses are classified into 3 groups (<0.1 mSv, 0.1-0.3 mSv, and >0.3 mSv). Air sampling methods are determined based on the dose estimates. Detailed dose assessment is performed using air sampling and particulate characterization. The final dose results are classified into 4 different levels (<0.1 mSv, 0.1-0.3 mSv, 0.3-1 mSv, and >1 mSv). Proper radiation protection measures are suggested according to the dose level. The developed dose assessment procedure was applied for NORM industries in Korea, including coal combustion, phosphate processing, and monazite handing facilities. The developed procedure provides consistent dose assessment results and contributes to the establishment of optimization of radiological protection in NORM industries

    Full Text Available The aim of this study was to find a new method for usage of the hazardous waste coming from recycling industry. Two hazardous wastes – aluminium recycling final dross or non-metallic product (NMP and lead – silica glass (LSG were investigated. It is generally considered that NMP is a process waste and subject to disposal after residual metal has been recovered from primary dross. NMP is impurities which are removed from the molten metal in dross recycling process and it could be defined as a hazardous waste product in aluminium recycling industry. LSG comes from fluorescence lamp recycling plant and could be classified as hazardous waste due to high amount of lead in the composition and re-melting problems. The new alkali activated material, which can be defined as porous building material, was created. Composition of this material consisted of aluminium recycling waste, recycled fluorescent lamp LSG, sintered kaolin clay as well as commercially available alkali flakes (NaOH and liquid glass (Na2SiO3 + nH2O. Physical and mechanical properties of the obtained material were tested. Density of the obtained material was from (460 – 550 kg/m3 and the total porosity was from 82 % – 83 %. The compressive strength of the material was in range from 1.1 MPa to 2.3 MPa. The thermal conductivity was determined.

    The high flux and density of X-rays produced at synchrotrons provide the microelectronics industry with a powerful probe of the structure and behavior of a wide array of solid materials that are being developed for use in devices of the future. They also are of great use in determining why currently-used materials and processes sometimes fail. This paper describes the X20 X-ray beamline facility operated by IBM at the National Synchrotron Light Source, and presents a series of three industry challenges and results that illustrate the variety of techniques used and problems addressed. The value of this research ranges from solving short-term, technically specific problems to increasing our academic understanding of materials in general. Techniques discussed include high-resolution diffraction, time-resolved diffraction, texture measurements, and grazing-incidence diffraction

    The aim of this study was to estimate the simultaneous recovery of industrial wood and raw material for energy wood from cuttings in Finland during the next 50 years. Two cutting scenarios (maximum and sustainable cuttings) and two climate scenarios (current and changing climate) were analysed to determine their impacts on harvesting potential. The analysis was carried out using sample plot and tree data from the ninth National Forest Inventory and a management-oriented large-scale forestry model (MELA) into which the transfer functions based on physiological modelling were incorporated to describe the impacts of climate change. Depending on the climate scenario, the volume of potential recovery of industrial wood in the maximum cutting scenario during the period 2003-2013 varied from 103 to 105 million m 3 a -1 , while the amount of potential energy wood raw material was 35 Tg a -1 . During the period 2043-2053, in the current climate scenario, the potential recovery of industrial wood was 64 million m 3 a -1 and energy wood raw material 22 Tg a -1 , and in the changing climate scenario, 85 million m 3 a -1 and 29 Tg a -1 , respectively. In the sustainable cutting scenario, depending on the climate scenario used, the potential recovery of industrial wood during the period 2003-2013 varied from 74 to 76 million m 3 a -1 , while the amount of potential energy wood was 25 Tg a -1 . During the period 2043-2053, in the current climate scenario, the potential recovery of industrial wood was 80 million m 3 a -1 and energy wood raw material 26 Tg a -1 , and in the changing climate scenario, 88 million m 3 a -1 and 29 Tg a -1 , respectively.

    Mechanical responses of three gamma titanium aluminides (TiAls) (denoted as Alloy A, Alloy B and Alloy C) subjected to dynamic scratching were studied by using a single-grit pendulum (rotating) scratch tester. The maximum depth of groove was ~ 0.07 mm, and the scratch velocity used was ~ 1.0 m/s. Normal and tangential forces were monitored. The material removal mechanisms were examined using a scanning electron microscope (SEM) and the scratches were measured by using a laser profilometer. The mechanical properties of the tested TiAls were characterized by the instantaneous specific energy, scratch resistance and scratch hardness as related to the depth of groove. Extensive thermal softening was observed in the dynamic scratch of the tested TiAls, which facilitated both the detachments of developing chips and the pile-ups of materials on side ridges. Sizable fractures were observed in the transverse direction on the tested TiAls; these fractures tended to participate in the chip formation, depending on the microstructure of the TiAl and the size of the scratch groove. Specific energy and scratch hardness are depth-dependent to various degrees for the tested TiAls. The materiel removal might be subjected to different mechanisms, but the overall response of materials can be effectively characterized by the HEM (Hwang, Evans and Malkin) model and the PSR (proportional specimen resistance) model. The obtained depth-independent specific energy and scratch hardness can be used to screen the candidate materials for the specific purpose depending on whether the application is scratch-dominant or impact-dominant. Among the three tested TiAls, the TiAl with larger colony or grain size exhibits a stronger capability of energy dissipation in the material loss or material removal (higher depth-independent specific energy), while the TiAl with smaller colony size show a higher resistance against the indentation (higher depth-independent scratch hardness). The observations and

    Many biological materials are hierarchically structured, with highly anisotropic structures and properties on several length scales. To characterize the mechanical properties of such materials, detailed testing methods are required that allow precise and site-specific measurements on several length scales. We propose a fracture toughness measurement technique based on notched focused ion beam prepared cantilevers of lower and medium micron size scales. Using this approach, site-specific fracture toughness values in dental enamel were determined. The usefulness and challenges of the method are discussed.

    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

  17. Decarbonising the energy intensive basic materials industry through electrification – Implications for future EU electricity demand

    2016-01-01

    The need for deep decarbonisation in the energy intensive basic materials industry is increasingly recognised. In light of the vast future potential for renewable electricity the implications of electrifying the production of basic materials in the European Union is explored in a what-if thought-experiment. Production of steel, cement, glass, lime, petrochemicals, chlorine and ammonia required 125 TW-hours of electricity and 851 TW-hours of fossil fuels for energetic purposes and 671 TW-hours of fossil fuels as feedstock in 2010. The resulting carbon dioxide emissions were equivalent to 9% of total greenhouse gas emissions in EU28. A complete shift of the energy demand as well as the resource base of feedstocks to electricity would result in an electricity demand of 1713 TW-hours about 1200 TW-hours of which would be for producing hydrogen and hydrocarbons for feedstock and energy purposes. With increased material efficiency and some share of bio-based materials and biofuels the electricity demand can be much lower. Our analysis suggest that electrification of basic materials production is technically possible but could have major implications on how the industry and the electric systems interact. It also entails substantial changes in relative prices for electricity and hydrocarbon fuels. - Highlights: • Energy intensive basic materials industry has a high share in EU greenhouse gas emissions. • Decarbonising these industries is very important, but still relatively unexplored. • Electrification is possible regarding renewable energy resources and technologies. • Combination with energy and materials efficiency, biofuels and CCS is crucial. • Electrification needs very high amounts of electricity and strong policies.

    , as well as in policy documents from e.g. the European Union, the concepts of circular econ- omy and closed-loop supply chains have received significant attention. One of the manifestations of these developments are industrial symbiosis networks. These networks are a collaborative effort to more...... sustainable production op- erations, and are characterized by a supply chain reconfiguration that uses one company’s wastes or by-products as a raw material for another company, avoiding waste disposal while also reducing material requirements. The re- sulting networks of relationships contribute to regional...... sustainable develop- ment efforts, and emphasize synergistic relations, community, and collabora- tion.

  19. Contribution of civilian industry to the management of military fissile materials

    2001-01-01

    The situation about using of highly enriched uranium (HEU) and weapon grade plutonium (WgPu) for nuclear fuel preparation in U.S.A. and Russian Federation is reviewed. A few remarks were concluded: (1) We stand at the onset of a process that will be lengthy and which is unlikely to stop with the elimination of the 700 t of HEU and 2 x 34.5 t of WgPu concerned so far. If the announced negotiation of the third START treaty concludes favorably, additional tonnages will have to be recycled, particularly on the Russian side whose estimated inventory is larger. (2) The time scales necessitated by the management of these materials should be no surprise. On the one hand, the aim is to reduce an arsenal built up during 45 years of a Cold War. And this return to civilian life of materials of military origin must be achieved in conditions of safety and bilateral or international safeguards (IAEA), which obviously did not constitute the primary concern of the powers who produced them. Besides, insofar as it enlists the services of civilian industry, this return must be carried out with due respect for the equilibrium of markets that are severely mauled today, in other words, in an orderly and progressive manner. (3) Finally, it is important to recognize that without the contribution of the nuclear power industry, the elimination of military fissile materials would raise problems at another scale and would inevitably lead to regrettable waste. It is to be hoped that this will jog the minds of those who urge a rapid end to nuclear energy, when all the evidence demonstrates that the best way to eliminate surplus weapon grade materials is to recycle them in a reactor, in other words, to destroy them or to denature them while generating electricity. (4) The civilian nuclear industry is happy to contribute concretely and significantly to the solution of a problem of surplus nuclear weaponry, while at the same time utilizing technologies successfully developed for power generation

    Radioactive deposits, often referred to as naturally occurring radioactive material scale, can, because of incompatibility of formation and injection waters, be formed inside production equipment of the oil and gas industry. These scales contain mainly 226 Ra and its daughter products, which can cause an exposure risk. The gamma ray dose rates, with the associated occupational doses in the oil and gas industry, and 226 Ra concentration in production water, crude oil and hard/soft scale samples were determined. Results obtained are discussed and compared to those from other studies

  1. The Specifics of the Internationalization Process of Czech SMEs in the Food Industry

    Full Text Available The aim of this paper is to define the specifics of the internationalization process of Czech small and medium-sized enterprises (SMEs in the food industry. The food industry is the largest manufacturing sector in the EU which consists mainly of SMEs. However, in the Czech Republic it has to face increasing imports of foreign food products because of growing globalization, while exports lag behind. Thus, enterprises should be encouraged to internationalize in a greater extent to maintain their competitiveness. The paper explores the main motives, barriers and risks involved in internationalization as perceived by these enterprises. The results are based on primary data obtained by questionnaire surveys performed among Czech food industry SMEs, thus it is based on data about SME’s real experiences and perception of interntaionalization process. According to our results, Czech SMEs from food industry are driven to internationalize mainly by their efforts to grow or by unsolicited foreign demand for their product. However, as the biggest barriers are perceived those connected with the lack of knowledge about foreign market and administrative requirements. The identified motives and barriers are compared with results of similar researches from Slovakia and Poland. Moreover, the results of Czech SMEs risk perception in internationalization are depicted in risk matrix which assess not only the effect of risk but also the possibility of its occurrence.

    Full Text Available In order to explore the propagation law of the impact elastic wave on the platform, the experimental platform is built by using the specific isotropic materials and anisotropic materials. The glass cloth epoxy laminated plate is used for anisotropic material, and an organic glass plate is used for isotropic material. The PVDF sensors adhered on the specific materials are utilized to collect data, and the elastic wave propagation law of different thick plates and laminated plates under impact conditions is analyzed. The Experimental results show that in anisotropic material, transverse wave propagation speed along the fiber arrangement direction is the fastest, while longitudinal wave propagation speed is the slowest. The longitudinal wave propagation speed in anisotropic laminates is much slower than that in the laminated thick plates. In the test channel arranged along a particular angle away from the central region of the material, transverse wave propagation speed is larger. Based on the experimental results, this paper proposes a material combination mode which is advantageous to elastic wave propagation and diffusion in shock-isolating materials. It is proposed to design a composite material with high acoustic velocity by adding regularly arranged fibrous materials. The overall design of the barrier material is a layered structure and a certain number of 90°zigzag structure.

    Full Text Available Filter treatment may be a viable means for removing the nitrate (NO3−, phosphate (PO43−, and pesticides discharged with agricultural drainage waters that cause adverse environmental impacts within the U.S. on local, regional, and national scales. Laboratory batch test screening for agricultural drainage water treatment potential was conducted on 58 industrial product/byproduct filter materials grouped into six categories: (1 high carbon content media; (2 high iron content media; (3 high aluminum content media; (4 surfactant modified clay/zeolite; (5 coal combustion residuals; and (6 spent foundry sands. Based on a percent contaminant removal criteria of 75% or greater, seven industrial products/byproducts were found to meet this standard for NO3− alone, 44 met this standard for PO43−, and 25 met this standard for the chlorinated triazine herbicide, atrazine. Using a 50% or greater contaminant removal criteria, five of the industrial product/byproduct filter materials exhibited potential for removing NO3−, PO43−, and atrazine together; eight showed capability for combined NO3− and PO43− removal; 21 showed capability for combined PO43− and atrazine removal; and nine showed capability for combined NO3− and atrazine removal. The results of this study delineated some potential industrial product/byproduct filter materials for drainage water treatment; however, a complete feasibility evaluation for drainage water treatment of any of these filter materials will require much more extensive testing.

    Full Text Available Material selection is a challenging issue in manufacturing processes while the inappropriate selected material may lead to fail the manufacturing process or end user experience especially in high-tech industries such as aircraft and shipping. Every material has different quantitative and qualitative criteria which should be considered simultaneously when assessing and selecting the right material. A weighted linear optimization method (WLOM in the class of data envelopment analysis which exists in literature is adopted to address material selection problem while accounting for both qualitative and quantitative criteria. However, it is demonstrated the adopted WLOM method is not able to produce a full ranking vector for the material selection problems borrowed from the literature. Thus, an augmented common weight data envelopment analysis model (ACWDEA is developed in this paper with the aim of eliminating deficiencies of WLOM model. The proposed ACWDEA is able to produce full ranking vector in decision making problems with less computational complexities in superior to the WLOM. Two material selection problems are solved and results are compared with WLOM and previous methods. Finally, the robustness and effectiveness of the proposed ACWDEA method are evaluated through Spearman’s correlation tests.

    1994-01-01

    Permanent magnets are of great industrial importance in industrial drives, consumer products, computers, and automobiles. Since 1970, new classes of magnet materials have been developed. This book reviews the older and newer materials and is presented as a comprehensive design text for permanent magnets and their applications. After an initial chapter on the fundamentals of magnetism, the author discusses magnetic physics considerations specific to permanent magnets and describes the fabrications and characteristics of commercial materials: alnico, samarium-cobalt, ferrite, and neodymium-iron-boron. Thermal stability, magnet design procedures, magnetic field analysis methods, and measurement methods are discussed in subsequent chapters, followed by a concluding chapter reviewing commercial and industrial products that use permanent magnets. The chapter on thermal properties of magnet materials is of particular interest, bringing together information not readily found elsewhere. The review of applications is also deserving of attention, specifically the sections on motors and actuators. Although particle accelerator applications are discussed, the use of permanent magnet sextuples in modern ECR ion sources is not mentioned

    The polarization and diffraction characteristics of x-rays incident upon a magnetic material are manipulated to provide a desired magnetic sensitivity in the material. The contrast in diffracted intensity of opposite helicities of circularly polarized x-rays is measured to permit separation of magnetic signals by element type and by atomic environment. This allows for the direct probing of magnetic signals from elements of the same species in nonequivalent atomic environments to better understand the behavior and characteristics of permanent magnetic materials. By using known crystallographic information together with manipulation of the polarization of x-rays having energies tuned near element-specific electronic excitations and by detecting and comparing the incident and diffracted photons at the same frequency, more accurate magnetic measurements can be made over shorter observation periods.

    The interaction design of e-Textile products are often characterized by conventions adopted from electronic devices rather than developing interactions that can be specific to e-Textiles. We argue that textile materials feature a vast potential for the design of novel digital interactions....... Especially the shape-reformation capabilities of textiles may inform the design of expressive and aesthetically rewarding applications. In this chapter, we propose ways in which the textileness of e-Textiles can be better harnessed. We outline an e-Textile Interaction Design strategy that is based...... on defining the material-specificity of e-Textiles as its ability to deform in ways that match the expectations we have of textile materials. It embraces an open-ended exploration of textile-related interactions (for e.g. stretching, folding, turning-inside-out etc.) and their potential for electronic...

    In order to promote uniformity between jurisdictions, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has developed the National Directory for Radiation Protection, which is a regulatory framework that all Australian governments have agreed to adopt. There is a large and diverse range of industries involved in mining or mineral processing, and the production of fossil fuels in Australia. Enhanced levels of naturally occurring radionuclides can be associated with mineral extraction and processing, other industries (e.g. metal recycling) and some products (e.g. plasterboard). ARPANSA, in conjunction with industry and State regulators, has undertaken a review and assessment of naturally occurring radioactive material (NORM) management in Australian industries. This review has resulted in guidance on the management of NORM that will be included in the National Directory for Radiation Protection. The first NORM safety guide provides the framework for NORM management and addresses specific NORM issues in oil and gas production, bauxite, aluminium and phosphate industries. Over time further guidance material for other NORM-related industries will be developed. This presentation will provide an overview of the regulatory approach to managing NORM industries in Australia. (authors)

    2004-01-01

    This paper will summarize best practices in incident investigation in the chemical process industries and will provide examples from both the industry sector and specifically from NOVA Chemicals. As a sponsor of the Center for Chemical Process Safety (CCPS), an industry technology alliance of the American Institute of Chemical Engineers, NOVA Chemicals participates in a number of working groups to help develop best practices and tools for the chemical process and associated industries in order to advance chemical process safety. A recent project was to develop an update on guidelines for investigating chemical process incidents. A successful incident investigation management system must ensure that all incidents and near misses are reported, that root causes are identified, that recommendations from incident investigations identify appropriate preventive measures, and that these recommendations are resolved in a timely manner. The key elements of an effective management system for incident investigation will be described. Accepted definitions of such terms as near miss, incident, and root cause will be reviewed. An explanation of the types of incident classification systems in use, along with expected levels of follow-up, will be provided. There are several incident investigation methodologies in use today by members of the CCPS; most of these methodologies incorporate the use of several tools. These tools include: timelines, sequence diagrams, causal factor identification, brainstorming, checklists, pre-defined trees, and team-defined logic trees. Developing appropriate recommendations and then ensuring their resolution is the key to prevention of similar events from recurring, along with the sharing of lessons learned from incidents. There are several sources of information on previous incidents and lessons learned available to companies. In addition, many companies in the chemical process industries use their own internal databases to track recommendations from

  1. Route-specific analysis for radioactive materials transportation

    International Nuclear Information System (INIS)

    1986-01-01

    This report addresses a methodology for route-specific analysis, of which route-selection is one aspect. Identification and mitigation of specific hazards along a chosen route is another important facet of route-specific analysis. Route-selection and route-specific mitigation are two tools to be used in minimizing the risk of radioactive materials transportation and promoting public confidence. Other tools exist to improve the safety of transportation under the Nuclear Waste Policy Act. Selection of a transportation mode and other, non-route-specific measures, such as improved driver training and improved cask designs, are additional tools to minimize transportation risk and promote public confidence. This report addresses the route-specific analysis tool and does not attempt to evaluate its relative usefulness as compared to other available tools. This report represents a preliminary attempt to develop a route-specific analysis methodlogy. The Western Interstate Energy Board High-Level Waste Committee has formed a Route-Specific Analysis Task Force which will build upon the methodology proposed in this Staff Report. As western states continue to investigate route-specific analysis issues, it is expected that the methodology will evolve into a more refined product representing the views of a larger group of interested parties in the West

  2. Encapsulation in the food industry: a review.

    Encapsulation involves the incorporation of food ingredients, enzymes, cells or other materials in small capsules. Applications for this technique have increased in the food industry since the encapsulated materials can be protected from moisture, heat or other extreme conditions, thus enhancing their stability and maintaining viability. Encapsulation in foods is also utilized to mask odours or tastes. Various techniques are employed to form the capsules, including spray drying, spray chilling or spray cooling, extrusion coating, fluidized bed coating, liposome entrapment, coacervation, inclusion complexation, centrifugal extrusion and rotational suspension separation. Each of these techniques is discussed in this review. A wide variety of foods is encapsulated--flavouring agents, acids bases, artificial sweeteners, colourants, preservatives, leavening agents, antioxidants, agents with undesirable flavours, odours and nutrients, among others. The use of encapsulation for sweeteners such as aspartame and flavours in chewing gum is well known. Fats, starches, dextrins, alginates, protein and lipid materials can be employed as encapsulating materials. Various methods exist to release the ingredients from the capsules. Release can be site-specific, stage-specific or signalled by changes in pH, temperature, irradiation or osmotic shock. In the food industry, the most common method is by solvent-activated release. The addition of water to dry beverages or cake mixes is an example. Liposomes have been applied in cheese-making, and its use in the preparation of food emulsions such as spreads, margarine and mayonnaise is a developing area. Most recent developments include the encapsulation of foods in the areas of controlled release, carrier materials, preparation methods and sweetener immobilization. New markets are being developed and current research is underway to reduce the high production costs and lack of food-grade materials.

  3. Material Removal and Specific Energy in the Dynamic Scratching of Gamma Titanium Aluminides

    2006-11-30

    Mechanical responses of three gamma titanium aluminides (TiAls) (denoted as Alloy A, Alloy B and Alloy C) subjected to dynamic scratching were studied by using a single-grit pendulum (rotating) scratch tester. The maximum depth of groove was {approx} 0.07 mm, and the scratch velocity was {approx} 1.0 m/s. Normal and tangential forces were monitored. The material removal mechanisms were examined using a scanning electron microscope (SEM) and the scratches were measured by using a laser profilometer. The mechanical properties of the tested TiAls were characterized by the instantaneous specific energy, scratch resistance and scratch hardness as related to the groove depth. Extensive thermal softening was observed in the dynamic scratch test of the TiAls, which facilitated both the detachment of developing chips and pile-up of material on side ridges. Sizable fractures were observed in the transverse direction in the tested TiAls; these fractures tended to participate in the chip formation, depending on the microstructure of the TiAl and the size of the scratch groove. Specific energy and scratch hardness are depth-dependent to various degrees for the TiAls tested. The material removal might be subjected to different mechanisms, but the overall material response can be effectively characterized by the HEM (Hwang, Evans and Malkin) model and the PSR (proportional specimen resistance) model. The depth-independent specific energy and scratch hardness can be used to screen candidate materials for the applications that are scratch-dominated versus impact-dominated. Among the three tested TiAls, the TiAl with larger colony or grain size exhibits a stronger capability of energy dissipation during material removal (higher depth-independent specific energy), while the TiAl with smaller colony size shows a higher resistance to indentation (higher depth-independent scratch hardness). The observations and conclusions in this study can serve as a base line for the further

    2005-01-01

    A simple sample decomposition and laser fluorimetric determination of uranium at trace level is reported in certain refractory minerals, like ilmenite, rutile, zircon and monazite; environmental samples viz. soil and sediments; industrial waste materials, such as, coal fly ash and red mud. Ilmenite sample is decomposed by heating with ammonium fluoride. Rutile, zircon and monazite minerals are decomposed by fusion using a mixture of potassium bifluoride and sodium fluoride. Environmental and industrial waste materials are brought into solution by treating with a mixture of hydrofluoric and nitric acids. The laser induced fluorimetric determination of uranium is carried out directly in rutile, zircon and in monazite minerals and after separation in other samples. The determination limit was 1 μg x g -1 for ilmenite, soil, sediment, coal fly ash and red mud samples, and it is 5 μg x g -1 for rutile, zircon and monazite. The method is also developed for the optical fluorimetric determination of uranium (determination limit 10 μg x g -1 ) in ilmenite, rutile, zircon and monazite minerals. The methods are simple, accurate, and precise and they require small quantity of sample and can be applied for the routine analysis. (author)

    Highlights: • Sandwich panels optimization model. • Sandwich panels design procedure. • Study of sandwich panels for automotive vehicle flooring. • Study of sandwich panels for truck cabin exterior. - Abstract: The future of automotive industry faces many challenges in meeting increasingly strict restrictions on emissions, energy usage and recyclability of components alongside the need to maintain cost competiveness. Weight reduction through innovative design of components and proper material selection can have profound impact towards attaining such goals since most of the lifecycle energy usage occurs during the operation phase of a vehicle. In electric and hybrid vehicles, weight reduction has another important effect of extending the electric mode driving range between stops or gasoline mode. This paper adopts parametric models for design optimization and material selection of sandwich panels with the objective of weight and cost minimization subject to structural integrity constraints such as strength, stiffness and buckling resistance. The proposed design procedure employs a pre-compiled library of candidate sandwich panel material combinations, for which optimization of the layered thicknesses is conducted and the best one is reported. Example demonstration studies from the automotive industry are presented for the replacement of Aluminum and Steel panels with polypropylene-filled sandwich panel alternatives

    The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNL’s unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted projects with industry members. ORNL has the capabilities in place and the expertise required to understand how basic material properties including defects, impurities, and grain boundaries affect the solar cell performance. ORNL also has unique processing capabilities to optimize the manufacturing process for fabrication of high efficiency and low cost solar cells. ORNL recently established the Center for Advanced Thin-film Systems (CATS), which contains a suite of optical and electrical characterization equipment specifically focused on solar cell research. Under this project, ORNL made these facilities available to industrial partners who were interested in pursuing collaborative research toward the improvement of their product or manufacturing process. Four specific projects were pursued with industrial partners: Global Solar Energy is a solar industry leader in full scale production manufacturing highly-efficient Copper Indium Gallium diSelenide (CIGS) thin film solar material, cells and products. ORNL worked with GSE to develop a scalable, non-vacuum, solution technique to deposit amorphous or nanocrystalline conducting barrier layers on untextured stainless steel substrates for fabricating high efficiency flexible CIGS PV. Ferro Corporation’s Electronic, Color and Glass Materials (“ECGM”) business unit is currently the world’s largest supplier of metallic contact materials in the crystalline solar cell marketplace. Ferro’s ECGM business unit has been the world's leading supplier of thick film metal pastes to the crystalline silicon PV industry for more than 30 years, and has had operational

    Manual material handling is one of the major health and safety hazards in industry. This study aims to assess the lifting tasks, before and after intervention using NIOSH lifting equation and Manual Handling Assessment Charts (MAC). This interventional study was performed in 2011 in a tile manufacturing industry in Hamadan, located in the West of Iran. The prevalence of musculoskeletal discomfort was determined using Nordic musculoskeletal questionnaire. In order to assess the risk factors related to lifting and identify the high-risk activities, MAC and NIOSH lifting equation were used. In intervention phase, we designed a load-carrying cart with shelves capable of moving vertically up and down, similar to scissor lifts. After intervention, the reassessment of risk factors was conducted to determine the success of the intervention and to compare risk levels before and after intervention using t-test. The outputs of MAC and NIOSH lifting equation assessments before intervention revealed that all activities were at high-risk level. After intervention, the risk level decreased to average level. In conclusion, the results of intervention revealed a considerable decrease in risk level. It may be concluded that the given intervention was acceptable and favorably effective in preventing musculoskeletal disorders especially low back pain.

    The article describes the current state of knowledge and practice in Poland concerning recycling as a method of reuse of chosen groups of waste materials in building industry. The recycling of building scraps is imposed by environmental, economic and technological premises. The issue of usage of sewage residues is becoming a problem of ever -growing gravity as the presence of the increasing number of pernicious contaminants makes their utilization for agricultural purposes more and more limited. The strategies of using waste materials on Polish building sites were analyzed. The analysis of predispositions to salvage for a group of traditional materials, such as: timber, steel, building debris, insulation materials, plastics, and on the example of new materials, such as: artificial light aggregates made by appropriate mixing of siliceous aggregates, glass refuses and sewage residues in order to obtain a commodity which is apt for economic usage also was made in the article. The issue of recycling of waste materials originating from building operations will be presented in the context of the binding home and EU legal regulations. It was proved that the level of recycling of building wastes in Poland is considerably different from one which is achieved in the solid market economies, both in quantity and in assortment. The method of neutralization of building refuses in connection with special waste materials, which are sewage sludge that is presented in the article may be one of the alternative solutions to the problem of recycling of these wastes not only on the Polish scale.

    2016-09-01

    Full Text Available Whereas formerly metallic materials were used extensively and for various purposes in the machines manufacturing industry, nowadays new materials are sought that can replace the "conventional" machines manufacturing materials with new ones. This is especially challenging in areas where parts need to be able to withstand very tough conditions, such as high temperatures or large forces applied to them. The current paper intends to analyze some of the most widely used materials for high-strength applications. A special focus in this regard is on the one hand in fiber-reinforced composite materials with the polymer matrix and on the other hand on basalt. The most important properties, processing technologies and applications of these materials are analyzed and discussed and conclusions are drawn regarding their compatibility with the intended purpose.

    Chemical engineering processes and operations are closely involved in every step of the nuclear fuel cycle. Starting from mining and milling of the ore through the production of fuel and other materials and their use in nuclear reactors, fuel reprocessing, fissile material recycle and treatment and disposal of fission product wastes, each step presents a challenge to the chemical engineer to evolve and innovate processes and techniques for more efficient utilization of the energy in the atom. The requirement of high recovery of the desired components at high purity levels is in itself a challenge. ''Nuclear Grade'' specifications for materials put a requirement which very few industries can satisfy. Recovery of uranium and thorium from low grade ores, of heavy water from raw water, etc. are examples. Economical and large scale separation of isotopes particularly those of heavy elements is a task for which processess are under various stages of development. Further design of chemical plants such as fuel reprocessing plants and high level waste treatment plants, which are to be operated and maintained remotely due to the high levels of radio-activity call for engineering skills which are being continually evolved. In the reactor, analysis of the fluid mechanics and optimum design of heat removal system are other examples where a chemical engineer can play a useful role. In addition to the above, the activities in the nuclear industry cover a very wide range of chemical engineering applications, such as desalination and other energy intensive processes, radioisotope and radiation applications in industry, medicine and agriculture.

    In order to provide the industrial structures that are necessary for ecologically and economically effective waste management and recycling - from the collecting of valuable waste materials to the marketing of the secondary raw materials obtained -, the BDE (Bundesverband der Deutschen Entsorgungswirtschaft e.V., Federal Association of the German Waste Management Industry) considers that free movement of goods must be ensured in the whole European Union. This means Europe-wide prohibition of dumping of untreated waste, common European environmental standards and their enforcement. If the potential of waste materials is to be developed in Europe, politicians must develop consequent understanding of waste as a raw material and commodity. Europe needs open frontiers and free trade in this important sector. (orig.) [German] Um die fuer eine oekologisch und oekonomisch effektive Kreislaufwirtschaft zwingend erforderlichen industriellen Strukturen - von der Sammlung werthaltiger Abfaelle bis hin zur Vermarktung der gewonnenen Sekundaerrohstoffe - zu schaffen, muss aus Sicht des BDE fuer alle Abfallstroeme der Grundsatz der Warenverkehrsfreiheit im gesamten Bereich der Europaeischen Union gelten. Voraussetzungen dafuer sind ein europaweites Deponieverbot fuer unbehandelte Abfaelle, europaweit einheitliche Umweltstandards und ein einheitlicher Vollzug. Wenn wir tatsaechlich das Potenzial, das im europaeischen Abfallberg steckt, heben wollen, muss auch die Politik ein konsequentes Verstaendnis fuer die Ressource Abfall als Ware entwickeln. Wir brauchen in Europa fuer diesen wichtigen Stoffstrom offene Grenzen und freien Handel. (orig.)

    The IT security law forced the energy industry to implement system certifications for the first time in history. In contrast to most companies in the energy industry, which often only knew about product certifications, the energy industry now has to enter new territory. Certification companies receive their legitimation in Germany through DAkkS. The DAkkS is embedded in the context of European Union law. The work of the certification companies is determined by the specifications of the DAkkS as well as by the requirements of the ISO/IEC standards. These regulations should in any case be known to a certification customer so that he knows what a certification company does or does not do. In addition, a certification customer must also know which evidence must be presented in the sense of a reference standard against the certification company. The concrete evidence in this essay is based on an ISO/IEC 27001 certification in conjunction with the IT Security Catalog of the Bundesnetzagentur. With all this knowledge, the cooperation with the certification company will not be a problem for system certification.

  15. Postcards from the past: Archaeological and industrial analogs for deep repository materials

    1995-01-01

    Many recent performance assessments of deep geological repositories for radioactive wastes suggest that the engineered barrier system plays the cominant role in reducing releases of radionuclides to the surface environment. There is a considerable impetus to demonstrate the longevity of engineered barrier system components. Although many of the materials are familiar, the requirement for predictable behavior and longevity in a repository is unlike any other requirements of the past. A full appreciation of the acceptability of repository materials can only be reached from a combination of complementary field, laboratory, and natural analog studies. This article discusses analogs from archaelogy and industry. Topics covered include what makes a good analog; long term material behavior (from archeological studies) of metals, glass,cements and concrete, bitumens, and betonite; investigations of radionuclide transport and material interactions. 4 figs., 3 tabs

    Over the past decades, fusion has created a cooperative relationship between the DOE national laboratories, leading universities, and high technology industries. This relationship in the fusion community has helped to solve difficult technical problems, which will hopefully lead toward the commercialization of fusion. The US industry, with high technology skills, provides relevant cutting-edge designs, tools, and processes to help solve unique and technically challenging problems associated with fusion energy development. Together, these relationships have developed new and improved technologies and processes to achieve and demonstrate solutions to help advance fusion toward its ultimate goal. The benefits to industry, in terms of commercial applications to their product lines, are subjective. The involvement of US industry has been limited to a few high technology firms, with Boeing and General Atomics being the longest lasting and most involved. Widespread industrial involvement has been constrained with limited funding for the fusion budgets. Even with the funding constraints, industry has contributed to all aspects and systems for MFE and IFE experiments, demonstration reactors, and commercial power plant designs. While several technology and product spin-offs are identified and examined, the more prevalent transfer of information arises from subtle two-way transition of technologies between the fusion related efforts and those of the parent industrial firms. Examples of this transfer include CAD/CAM, independent product team structures, computer simulation/modeling/assessment, extended material property databases, tailored material processing, improved and lower cost fabrication processes, and component designs/applications. Specific examples of transitioned components or technologies involve superconducting magnets, neutral beam components, laser machining, and microwave/RF technologies

    As a developing country, Malaysia is fully committed to research and development especially for industrial development. One of priority fields is advanced materials and surface analysis of such materials is an important aspect in research. Among the tools for surface science analysis is x-ray photoelectron spectroscopy (XPS) which can be considered new to this country. The industrial sector is also keen to solve their problems and developing their products using XPS. The microelectronic and electrical industries are interested in solving problems related to metal-metal joining , gold silica peeling, surface corrosion and surface coating. The glove industry uses XPS to solve problems due to staining and color fading of their products. Research conducted in universities and research institutes that mainly deal with catalysis, membranes for fuel cells, sensors, batteries, corrosion phenomena and interface interaction in coating finds XPS a useful technique for surface studies. Specific examples from various sectors will be presented in this paper. (Author)

    This study compares the thermodynamic performance of three industrial bread production chains: one that generates food waste, one that avoids food waste generation, and one that reworks food waste to produce new bread. The chemical exergy flows were found to be much larger than the physical exergy consumed in all the industrial bread chains studied. The par-baked brown bun production chain had the best thermodynamic performance because of the highest rational exergetic efficiency (71.2%), the lowest specific exergy losses (5.4 MJ/kg brown bun), and the almost lowest cumulative exergy losses (4768 MJ/1000 kg of dough processed). However, recycling of bread waste is also exergetically efficient when the total fermented surplus is utilizable. Clearly, preventing material losses (i.e. utilizing raw materials maximally) improves the exergetic efficiency of industrial bread chains. In addition, most of the physical (non-material related) exergy losses occurred at the baking, cooling and freezing steps. Consequently, any additional improvement in industrial bread production should focus on the design of thermodynamically efficient baking and cooling processes, and on the use of technologies throughout the chain that consume the lowest possible physical exergy. - Highlights: • Preventing material losses is the best way to enhance the exergetic efficiency. • Most of the physical exergy losses occur at the baking, cooling and freezing steps. • Par-baking “saves” chemical exergy but consumes an equal amount of physical exergy

    In this book the author provides a description of nuclear measurements in industry, covering the physical principles, methods, instruments and equipment, and industrial applications. One of the great advantages of industrial nuclear measurements is that their use ensures the optimum use of raw material. The increasing cost of raw materials makes it essential to adhere strictly to the standards and prescriptions related to the product and this is possible only by the application of continuous and accurate measurements. As a result, the importance of nuclear instruments is rapidly growing particularly in fields where the application of alternative methods is not possible. This is illustrated by several practical examples described in the book. Similarly important are nuclear measuring the process control equipment which serve to optimize the use of energy in industrial processes

    The object of research in this work is the silica-containing waste of oil extraction industry - the waste kieselghur (diatomite) sludge from precoat filtering units, used for the purification of vegetable oils from organic impurities. As a result of the thermal modification of the sludge, which contains up to 70% of organic impurities, a finely-dispersed low-porous carbonaceous mineral sorption material is formed. The modification of the sludge particles surface causes the substantial alteration of its physical, chemical, adsorption and structural properties - the organic matter is charred, the particle size is reduced, and on the surface of diatomite particles a carbon layer is formed, which deposits in macropores and partially occludes them. The amount of mesopores is increased, along with the specific surface of the obtained product. The optimal temperature of sludge modification is 500°C. The synthesized carbonaceous material can be used as an adsorbing agent for the purification of wastewater from heavy metal ions. The sorption capacity of Cu2+ ions amounted to 14.2 mg·g-1 and for Ni2+ ions - 17.0 mg·g-1. The obtained values exceed the sorption capacity values of the initial kieselghur, used as a filtering charge, for the researched metal ions.

  6. Long term energy and materials strategies for reduction of industrial CO2 emissions. A case study for the iron and steel industry

    International Nuclear Information System (INIS)

    Gielen, D.J.

    1997-01-01

    Greenhouse gas emissions emerged in the last decade as a key environmental problem on the political agenda. The most important greenhouse gas is carbon dioxide (CO 2 ). This gas results from the combustion of fossil fuels (natural gas, oil and coal). As a consequence, greenhouse gas emission reduction is closely related to energy policies. Even a stabilization of the atmospheric CO 2 concentrations at a level of 750 ppm (parts per million), more than twice the current level, implies a reduction of global emissions by 50% in the next century. The world population will simultaneously double and the capita energy consumption will increase. As a consequence, the Western industrialized countries will have to reduce their per capita emissions by more than a factor four. Such a policy goal will significantly affect the future industrial production structure. Approximately 4% of the global CO 2 emissions can be attributed to the production of iron and steel. This sector is the most important industrial source of CO 2 . The case study for the iron and steel industry will be discussed in this paper in order to illustrate the impact of significant CO 2 emission mitigation on the industry. The goal is to show the consequences of CO 2 policies for R and D planning and investment decisions. The notion that the iron and steel industry will be affected by CO 2 policies is not new; a number of studies have addressed this issue before. These studies have compared steel production technologies and emission reduction options within the iron and steel production sector. In this paper, the emission reduction in the iron and steel industry is analyzed within the framework of the changing (inter-)national energy and materials system configuration. This includes all production, conversion and consumption processes. The impact of CO 2 policies on the optimal choice of steel production technologies and on the competitiveness of steel compared to other materials will be discussed. This paper

    Comparison of analytical results with finite element results for analysis of isotropic material multicell beams subjected to free torsion case is the main idea of this paper. Progress in the fundamentals and applications of advanced materials and their processing technologies involves costly experiments and prototype testing for reliability. The software development for design analysis of structures with advanced materials is a low cost but challenging research. Multicell beams have important industrial applications in the aerospace and automotive sectors. This paper explains software development to test different materials in design of a multicell beam. Objective of this paper is to compute the torsional loading of multicell beams of isotropic materials for safe design in both symmetrical and asymmetrical geometries. Software has been developed in Microsoft Visual Basic. Distribution of Saint Venant shear flows, shear stresses, factors of safety, volume, mass, weight, twist, polar moment of inertia and aspect ratio for free torsion in multicell beam have been calculated using this software. The software works on four algorithms, these are, Specific geometry algorithm, material selection algorithm, factor of safety algorithm and global algorithm. User can specify new materials analytically, or choose a pre-defined material from the list, which includes, plain carbon steels, low alloy steels, stainless steels, cast irons, aluminum alloys, copper alloys, magnesium alloys, titanium alloys, precious metals and refractory metals. Although this software is restricted to multicell beam comprising of three cells, however future versions can have ability to address more complicated shapes and cases of multicell beams. Software also describes nomenclature and mathematical formulas applied to help user understand the theoretical background. User can specify geometry of multicell beam for three rectangular cells. Software computes shear flows, shear stresses, safety factors

    Several ferrous and non ferrous metallurgical wastes, slag, powdered wastes, alkaline liquors, etc., can be used as binding materials to produce new building materials. These materials can be used in place of concretes made of cement, crushed stones, sand and gravel mixtures in several applications, road, industrial and airport foundations, etc. They are leaching resistant, so heavy metals do not migrate to the environment. These new materials, with a new structure, are obtained by mixing in right proportion of two or three industrial wastes or with mixtures of two of them and natural soils without any addition of traditional binders like and without heating. The main advantages are the solution of the problem of disposal of industrial wastes and the lower cost of the new materials, 5 to 6 times cheaper than traditional. Several examples of roads existing in Russia, even in Siberia and other northern regions, demonstrate the benefit of this process because after 20 years they still offer a good performance.

    This study was conducted to characterize industrial wastes for formulation of emulsified modified bitumen (EMB) in relation to their physical characteristic and elemental composition. This analysis will give information either raw materials from industrial wastes can be used for EMB formulation. Bitumen is produced from crude oil that is extracted from the ground which categorizes the crude oil as one of the non-renewable form of product. A vast environmental problem issues arises in Malaysia cause by the excessive manufacturing activity that lead to a miss-management of industrial waste has leads to the used of industrial waste in the EMB formulation. Industrial waste such as polystyrene, polyethylene and used automotive oil can be used as alternative to formulate bitumen. Then a suitable emulsifier needs to be added to produce the final product which is EMB. The emulsifier will yield a charge depends on its properties to bind the oily bitumen with water. Physical characteristic studies were performed by thermogravimetric Analysis (TGA), differential scanning calorimetry (DSC), flash point test, density rest and moisture content test. Fourier Transform Infrared Spectroscopy (FTIR) analysis was measured to determine the material’s molecular composition and structure.

    2015-02-01

    This project reviewed published IAEA materials and other documents on safety culture with specific references to industrial radiography. Safety culture requires all duties important to safety to be carried out correctly, with alertness, due thought and full knowledge, sound judgment and a proper sense of accountability. The development and maintenance of safety culture in an operating organization has to cover management systems, policies, responsibilities, procedures and organizational arrangements. The essence is to control radiation hazard, optimize radiation protection to prevent or reduce exposures and mitigate the consequences of accidents and incidents. To achieve a high degree of safety culture appropriate national and international infrastructure should exist to ensure effective training of workers and management system that supports commitment to safety culture at all level of the organization; management, managers and workforce. The result of the review revealed that all accidents in industrial radiography facilities were due to poor safety culture practices including inadequate regulatory control oversight. Some recommendations are provided and if implemented could improve safety culture leading to good safety performance which will significantly reduce accidents and their consequences in industrial radiography. These examples call for a review of safety culture in Industrial radiography. (au)

  11. Derivation of Accident-Specific Material-at-Risk Equivalency Factors

    Jason P. Andrus; Dr. Chad L. Pope

    2012-05-01

    A novel method for calculating material at risk (MAR) dose equivalency developed at the Idaho National Laboratory (INL) now allows for increased utilization of dose equivalency for facility MAR control. This method involves near-real time accounting for the use of accident and material specific release and transport. It utilizes all information from the committed effective dose equation and the five factor source term equation to derive dose equivalency factors which can be used to establish an overall facility or process MAR limit. The equivalency factors allow different nuclide spectrums to be compared for their respective dose consequences by relating them to a specific quantity of an identified reference nuclide. The ability to compare spectrums to a reference limit ensures that MAR limits are in fact bounding instead of attempting to establish a representative or bounding spectrum which may lead to unintended or unanalyzed configurations. This methodology is then coupled with a near real time material tracking system which allows for accurate and timely material composition information and corresponding MAR equivalency values. The development of this approach was driven by the complex nature of processing operations in some INL facilities. This type of approach is ideally suited for facilities and processes where the composition of the MAR and possible release mechanisms change frequently but in well defined fashions and in a batch-type nature.

    Flexibility and innovation at creating shapes, adapting processes, and modifying materials characterize composites materials, a "high-tech" industry. However, the absence of standard manufacturing processes and the selection of materials with defined properties hinder the configuration of the composites materials supply chain. An interesting alternative for a "high-tech" industry such as composite materials would be to review supply chain lessons and practices in "low-tech" industries such as food. The main motivation of this study is to identify lessons and practices that comprise innovations in the supply chain of a firm in a perceived "low-tech" industry that can be used to provide guidelines in the design of the supply chain of a "high-tech" industry, in this case composite materials. This work uses the case study/site visit with analogy methodology to collect data from a Spanish leading producer of fresh fruit juice which is sold in major European markets and makes use of a cold chain. The study highlights supply base management and visibility/traceability as two elements of the supply chain in a "low-tech" industry that can provide guidelines that can be used in the configuration of the supply chain of the composite materials industry.

    2011-01-01

    The generation of electricity in the United States from wind-powered turbines is increasing. An understanding of the sources and abundance of raw materials required by the wind turbine industry and the many uses for these materials is necessary to assess the effect of this industry's growth on future demand for selected raw materials relative to the historical demand for these materials. The U.S. Geological Survey developed estimates of future requirements for raw (and some recycled) materials based on the assumption that wind energy will supply 20 percent of the electricity consumed in the United States by 2030. Economic, environmental, political, and technological considerations and trends reported for 2009 were used as a baseline. Estimates for the quantity of materials in typical "current generation" and "next generation" wind turbines were developed. In addition, estimates for the annual and total material requirements were developed based on the growth necessary for wind energy when converted in a wind powerplant to generate 20 percent of the U.S. supply of electricity by 2030. The results of the study suggest that achieving the market goal of 20 percent by 2030 would require an average annual consumption of about 6.8 million metric tons of concrete, 1.5 million metric tons of steel, 310,000 metric tons of cast iron, 40,000 metric tons of copper, and 380 metric tons of the rare-earth element neodymium. With the exception of neodymium, these material requirements represent less than 3 percent of the U.S. apparent consumption for 2008. Recycled material could supply about 3 percent of the total steel required for wind turbine production from 2010 through 2030, 4 percent of the aluminum required, and 3 percent of the copper required. The data suggest that, with the possible exception of rare-earth elements, there should not be a shortage of the principal materials required for electricity generation from wind energy. There may, however, be selective

    Grocery retail work can be physically demanding as material handler’s tasks involve manual lifting, lowering, carrying, pushing and pulling loads. The nature of this work puts them at a risk for serious low back pain, shoulder pain and other musculoskeletal injuries. This study was conducted by using two different types of tools which were Nordic Musculoskeletal Questionnaire (NMQ) as a survey and Washington Industrial Safety and Health Act (WISHA) Checklist as a direct observation method. Among 46 males and 14 females material handlers were involved throughout this study. For NMQ, the highest body part trouble in the last 12 months was low back pain (88.3%), followed by upper back (68.3%), neck (55.3%) and shoulder (36.7%). While for WISHA Checklist, most of them experienced hazard level involving awkward posture and high hand force. From the research conducted, musculoskeletal disorders (MSDs) and ergonomic risk factors (ERFs) do related as it showed that musculoskeletal disorders may arise if the workers ignored the safety in ergonomic hazards.

  17. Industries processing naturally occurring radioactive materials: twenty years of emission data in the Netherlands

    This paper provides a review of the dose assessment of discharges to air of two industries processing NORM (Naturally Occurring Radioactive Materials) in the Netherlands. An industrial plant producing elemental phosphorus (thermal process, unique within Europe) reports since 1987 its emission data to the Dutch Ministry of the Environment (VROM: Ministry of Housing, Spatial Planning and the Environment). This plant accounts for the highest release of Po-210 to air in the Netherlands, with a yearly average of approximately 500 GBq. Other significant NORM discharges to air arise from an industrial plant with blast-furnaces for steel production. Yearly discharges fall under permit, and are reported, since 1993. RIVM, the National Institute for Public Health and the Environment, is tasked by the Ministry to assess the dose to the general public arising from these discharges to air. Air transport modelling is used to determine both air concentration (for inhalation exposure) and deposition rate of the radionuclides. A (conservative) committed ingestion dose is determined by modelling the uptake of radionuclides from contaminated farmland, and assuming a food basket to be fairly representative for the population of the Netherlands. Discharges to water in the Netherlands have decreased in the past twenty years, due both to the closure of two phosphoric acid plants a decade ago and the improved treatment of waste fluids by other NORM industries. The collective dose assessed from discharges to air since 1987 is presented here. (author)

    The United States Environmental Protection Agency has just released for public comment its so-called multi-sector industry specific storm water permit. This permit -- developed in response to the 730 group storm water permit applications submitted in 1992 to EPA -- proposes the establishment of specific runoff sampling and facility design requirements for at least two petroleum industry sectors. This proposed permit establishes specific conditions for the oil and gas extraction section (SIC group 13) and for lubricant manufacturers (SIC 2992). Permit conditions are also established for allied industrial sectors such as the chemical, transportation and asphalt materials industries. By most standards, the proposed permit is much tougher than EPA's baseline general permit for storm water discharges which was released in September of 1992. For example, under the proposal, most industries are required to perform periodic storm water sampling. EPA has also established storm water effluent and performance standards for several industrial categories. This paper will discuss the petroleum industry specific conditions of the new permit. The paper will also discuss the results of the industry-wide storm water sampling efforts undertaken by more than 300 oil patch facilities across the country. In particular, sampling results will be discussed in the context to the permit conditions proposed by EPA. The paper will also discuss strategies for dealing with the new permits

    An outline is given of the transport of radioactive material in the nuclear industry in China over the past 30 years (1955-1985) (excluding Taiwan). During 1955-1985, the freight volume of packages of radioactive material was some 4.50x10 6 items. The total activity was about 4.64x10 5 TBq. The total transport distance was 2.10x10 8 km. The available results show that annual individual doses to transport workers are rather low. Much attention has been paid to the safe transport of the radioactive material. Hence, no accident with serious radiological effects on transport workers and the public has ever happened during the past 30 years. The paper also discusses how to strengthen the surveillance and administration, and the radiation protection of radioactive material transport, etc. (author)

    Industrial radiography and especially gamma-radiography, has established itself as a very powerful tool in non-destructive testing. Unfortunately there is an amount of risk attached to the use of industrial radiography. The primary causes of radiography accidents include: working conditions, equipment failure and lack of supervisory control. To alleviate the radiological risks involved with gamma-radiography, the Atomic Energy Corporation (AEC) has imposed various conditions for the possession, use, and conveyance of radioactive material. This includes personnel training and equipment specifications

    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

    1996-01-01

    The reliability of nuclear installations is a fundamental point for the exploitation of nuclear energy. It requires an extensive knowledge of the behaviour of materials in the operating conditions and during the expected service life of the installations. In nuclear power plants multiple risks of failure can exist and are expressed by corrosion and deformation phenomena or by modification in the mechanical characteristics of materials. The knowledge of the evolution with time of a given material requires to take into account the data relative to the material itself, to its environment and to the physical conditions of this environment. The study of materials aging needs a more precise knowledge of the kinetics of phenomena at any scale and of their interactions, and a micro- or macro-modeling of their behaviour during long periods of time. This paper gives an overview of the aging phenomena that occur in the structural materials involved in PWR and fast neutron reactors: thermal aging, generalized corrosion, corrosion under constraint, intergranular corrosion, crack growth under loading, wear, irradiation etc..

    The market for processed food is rapidly growing. The industry needs methods for "processing with care" leading to high quality products in order to meet consumers' expectations. Processing influences the quality of the finished product through various factors. In carrot baby food, these are the raw material, the pre-processing and storage treatments as well as the processing conditions. In this study, a quality assessment was performed on baby food made from different pre-processed raw materials. The experiments were carried out under industrial conditions using fresh, frozen and stored organic carrots as raw material. Statistically significant differences were found for sensory attributes among the three autoclaved puree samples (e.g. overall odour F = 90.72, p processed from frozen carrots show increased moisture content and decrease of several chemical constituents. Biocrystallization identified changes between replications of the cooking. Pre-treatment of raw material has a significant influence on the final quality of the baby food.

    Full Text Available Future professionals in fields, which are in increasing demand on the labour market, need “Learning in Depth”. Such approach ensures that every student becomes familiar with specific EU issues they may choose to specialize on. It can be achieved via employing different teaching methodologies and technics. Developing in-depths learning materials, including hand-outs, power point presentations, tutorials materials, video-lectures, open on-line courses are part of this approach. Instead of traditional face-to-face lecturing, it implements lectures with open discussions and game simulations, targeting in particular cross-cultural peculiarities for sustainable development fostering based on achievements of Industry 3.0 and Industry 4.0. Much of the attention would be paid for the debates as a part of learning by doing methodology. The basic here is the Karl Popper format of debates. Its extended format with Government and Opposition as two confronting parties is preferable, modelled by debates with NGOs participation, local government, business, developers, and active citizens. The other type of team-work projects are round tables discussions, during which global scale issues will be simulated, where each student would need to become an expert for solving critical issues. There would be specific tasks of modelling production/consumption nets, including those achieved by social and solidarity economies.

    This study analyzes foam concrete production efficiency. Research has shown the possibility of using a newly-designed protein-based foaming agent to produce porous materials using gypsum and cement binders. The protein foaming agent is obtained by alkaline hydrolysis of a raw mixture consisting of industrial waste in an electromagnetic field. The mixture consists of spent biomass of the Aspergillus niger fungus and dust from burning furnaces used in cement production. Varying the content of the foaming agent allows obtaining gypsum binder-based foam concretes with the density of 200-500 kg/m3 and compressive strength of 0.1-1.0 MPa, which can be used for thermal and sound insulation of building interiors. Cement binders were used to obtain structural and thermal insulation materials with the density of 300-950 kg/m3 and compressive strength of 0.9-9.0 MPa. The maximum operating temperature of cement-based foam concretes is 500°C because it provides the shrinkage of less than 2%.

    2013-09-01

    Full Text Available Profitable biomass conversion processes are highly dependent on the use of efficient enzymes for lignocellulose degradation. Among the cellulose degrading enzymes, beta-glucosidases are essential for efficient hydrolysis of cellulosic biomass as they relieve the inhibition of the cellobiohydrolases and endoglucanases by reducing cellobiose accumulation. In this review, we discuss the important role beta-glucosidases play in complex biomass hydrolysis and how they create a bottleneck in industrial use of lignocellulosic materials. An efficient beta-glucosidase facilitates hydrolysis at specified process conditions, and key points to consider in this respect are hydrolysis rate, inhibitors, and stability. Product inhibition impairing yields, thermal inactivation of enzymes, and the high cost of enzyme production are the main obstacles to commercial cellulose hydrolysis. Therefore, this sets the stage in the search for better alternatives to the currently available enzyme preparations either by improving known or screening for new beta-glucosidases.

    2012-01-01

    The objective of this paper is to describe a procedure to obtain maintainability indicators for industrial devices. This analysis can be helpful, among other cases, to compare systems, to achieve a better design regarding maintainability requirements, to improve this maintainability under specific industrial environment and to foresee maintainability problems due to eventual changes in a device operation conditions. This maintainability assessment can be carried out at any stage of the industrial asset life cycle. With this purpose, this work first introduces the notion of maintainability and the implementation of assessment indicators, including some important requirements to perform that. Then, a brief literature review is presented, including the definition of the main concepts, which are later used in the paper. After studying the maintenance levels and the maintainability attributes, both terms are linked, leading all this analysis to the assessment of the maintainability indicators. It follows a discussion about the information obtained through the maintainability assessment process and its computation into several maintainability indicators. The paper includes a case study, which implements the defined assessment into a practical scenario. Finally, the work concludes summarizing the more significant aspects and suggesting future researches.

    2009-01-01

    Radioactive waste is generated in a broad range of activities involving the use of radioactive material in medicine, industry, agriculture, research and education. The amounts of waste generated from these activities are often limited in volume and activity. However, they have to be managed as radioactive waste. While the principles and safety requirements are the same for managing any amount of radioactive waste, a number of issues have to be considered specifically in organizations conducting activities in which only small amounts of waste are generated. This is the case in particular in respect of spent and disused sealed radioactive sources. For activities involving the generation and management of small amounts of radioactive waste, the types of facilities concerned and the arrangements for waste management vary considerably. Furthermore, the types of radioactive waste differ from facility to facility. The safe management of small amounts of radioactive waste should therefore be given specific consideration. The nature of the radioactive waste generated in the various activities under consideration also varies greatly. It may be in the form of discrete sealed or unsealed radiation sources or process materials or consumable materials. Waste arises as a result of many activities, including: diagnostic, therapeutic and research applications in medicine. Process control and measurement in industry. And numerous uses of radioactive material in agriculture, geological exploration, construction and other fields. The radioactive waste under consideration can be in solid, liquid or gaseous form. Solid waste can include: spent or disused sealed sources. Contaminated equipment, glassware, gloves and paper. And animal carcasses, excreta and other biological waste. Liquid waste can include: aqueous and organic solutions resulting from research and production processes. Excreta. Liquids arising from the decontamination of laboratory equipment or facilities.

    Full Text Available In recent years, many process industries have been forced to drastically increase their product variety and adopt mass customization production strategies. Many of them have found that traditional bill of material (BOM processing systems do not sufficiently support the maintenance of the very large amounts of data (concerned with product structure demanded by these new production policies. Due to the use of BOM technology within the framework of integrated information systems, there is a demand for both (i a new representation of BOMs, able to deal efficiently with product variants and to handle decomposition-based production strategies, and (ii its corresponding BOM information processing system. This paper describes a conceptual representation that integrates elements of semantic relationships with object-oriented concepts to develop a data model for a hybrid bill of materials. The proposed semantic relationships include composed-of, decomposed-into, variant-of, restriction-of, and their corresponding reverse relationships. The conceptual model has been implemented using object-oriented data-based management system (OODBMS technology that allows creation of persistent Java objects. Preliminary tests show a remarkable reduction in the number of relationships when compared with former approaches.

    Leaching experiments, a mineralogical survey and larger samples are preferred when arsenic is present as discrete mineral phases. - Availability, mobility, (phyto)toxicity and potential risk of contaminants is strongly affected by the manner of appearance of elements, the so-called speciation. Operational fractionation methods like sequential extractions have been applied for a long time to determine the solid phase speciation of heavy metals since direct determination of specific chemical compounds can not always be easily achieved. The three-step sequential extraction scheme recommended by the BCR and two extraction schemes based on the phosphorus-like protocol proposed by Manful (1992, Occurrence and Ecochemical Behaviours of Arsenic in a Goldsmelter Impacted Area in Ghana, PhD dissertation, at the RUG) were applied to four standard reference materials (SRM) and to a batch of samples from industrially contaminated sites, heavily contaminated with arsenic and heavy metals. The SRM 2710 (Montana soil) was found to be the most useful reference material for metal (Mn, Cu, Zn, As, Cd and Pb) fractionation using the BCR sequential extraction procedure. Two sequential extraction schemes were developed and compared for arsenic with the aim to establish a better fractionation and recovery rate than the BCR-scheme for this element in the SRM samples. The major part of arsenic was released from the heavily contaminated samples after NaOH-extraction. Inferior extraction variability and recovery in the heavily contaminated samples compared to SRMs could be mainly contributed to subsample heterogeneity

    Full Text Available Mozambican poultry industry might be an option to facilitate people's access to animal protein, as well as to reduce the dependence on imports of the product, bringing jobs and income forth. This study aimed to characterize and to analyze the competitiveness of poultry industry in Mozambique. Porter’s Five Forces Model, which focuses on the five strengths that shape business competition, was applied. The results show a low level of competition within the industry, a limited supply of raw material and the fact that national products are commodities and competes with strong foreign participants. Domestic demand for chicken meat is increasing, but buyers base their decision mainly on price. Challenges include establishment of governance structure and policies for poultry sector and consumer welfare. Another alternative to improve the poultry industry in Mozambique is to promote technical cooperation with other countries, such as Brazil, in order to acquire specific structures for chicken production, genetic material and adequate nutrition.

    Pilot-scale Bacillus thuringiensis based biopesticide production (2000 L bioreactor) was conducted using starch industry wastewater (SIW) as a raw material using optimized operational parameters obtained in 15 L and 150 L fermenters. In pilot scale fermentation process the oxygen transfer rate is a major limiting factor for high product yield. Thus, the volumetric mass transfer coefficient (K L a) remains a tool to determine the oxygen transfer capacity [oxygen utilization rate (OUR) and oxygen transfer rate (OTR)] to obtain better bacterial growth rate and entomotoxicity in new bioreactor process optimization and scale-up. This study results demonstrated that the oxygen transfer rate in 2000 L bioreactor was better than 15 L and 150 L fermenters. The better oxygen transfer in 2000 L bioreactor augmented the bacterial growth [total cell (TC) and viable spore count (SC)] and delta-endotoxin yield. Prepared a stable biopesticide formulation for field use and its entomotoxicity was also evaluated. This study result corroborates the feasibility of industrial scale operation of biopesticide production using starch industry wastewater as raw material.

    This study leveraged a state workers' compensation claims database and machine learning techniques to target prevention efforts by injury causation and industry. Injury causation auto-coding methods were developed to code more than 1.2 million Ohio Bureau of Workers' Compensation claims for this study. Industry groups were ranked for soft-tissue musculoskeletal claims that may have been preventable with biomechanical ergonomic (ERGO) or slip/trip/fall (STF) interventions. On the basis of the average of claim count and rate ranks for more than 200 industry groups, Skilled Nursing Facilities (ERGO) and General Freight Trucking (STF) were the highest risk for lost-time claims (>7 days). This study created a third, major causation-specific U.S. occupational injury surveillance system. These findings are being used to focus prevention resources on specific occupational injury types in specific industry groups, especially in Ohio. Other state bureaus or insurers may use similar methods.

    Failure analysis of industrial boiler pipe has been done. The tested pipe material is carbon steel SA 178 Grade A refer to specification data which taken from Fertilizer Company. Steps in analysis were ; collection of background operation and material specification, visual inspection, dye penetrant test, radiography test, chemical composition test, hardness test, metallography test. From the test and analysis result, it is shown that the pipe failure caused by erosion and welding was shown porosity and incomplete penetration. The main cause of failure pipe is erosion due to cavitation, which decreases the pipe thickness. Break in pipe thickness can be done due to decreasing in pipe thickness. To anticipate this problem, the ppe will be replaced with new pipe

    2015-04-01

    The Verbano Cusio Ossola province (VCO, Piedmont, north-western Italy) is one of the most important Italian quarrying districts, due to the peculiarity and variety of its exploited rock types, mainly orthogneisses such as Serizzo and Beola, and subordinately granites, marbles and other rocks. The most important and extensively exploited ornamental stone from the VCO province is surely the Serizzo, commercialized in four main varieties, and representing about 70% of all the stone production from the VCO area. The protholith of the Serizzo is a Permian granite - granodiorite metamorphosed during the alpine events, and the rock-forming minerals are mainly quartz, K-feldspar, plagioclase (andesine), biotite, with variable amounts of muscovite and epidote (allanite). The other important ornamental stone of the VCO province is the Beola, a series of heterogeneous materials (mainly orthogneisses) with marked (mylonitic) foliation and strong mineralogical lineation, occurring in the median Ossola Valley; its production (15% of the whole stones of the VCO) is subordinated with respect to that of Serizzo. The mineralogical composition of the Beola varieties is similar to Serizzo, consisting of quite homogeneous quartz, K-feldspar (orthoclase or microcline), plagioclase, biotite and muscovite. The main differences relate to the grain size, the rock fabric (generally mylonitic) and to the presence of accessory/secondary minerals. Recent regulatory developments and the growing environmental awareness, require an increasing reuse of wastes deriving from the extraction and processing of dimension stones (up to 50 % of the extracted gross volume). Granite wastes from the VCO (Baveno pink granite and Montorfano white granite), after specific industrial treatments (crushing, sieving, drying, magnetic separation of biotite and hornblende), are used successfully as quartz-feldspars mix in the ceramic industry, with very low FeOtot content. On the other hand, other quartzose

    The technical specifications for the composition of nuclear fuels and materials used in Canada's CANDU reactors have been developed by AECL and materials manufacturers, taking into account considerations specific to their manufacture and the effect of minor impurities on fuel behaviour in reactor. Nitrogen and chlorine are examples of UO 2 impurities, however, where there is no technical specification limit. These impurities are present in the source materials or introduced in the fabrication process and are neutron activated to 14 C and 36 C1, which after 129 I , are the two most significant contributors to dose in safety assessments for the disposal of used fuel. For certain impurities, environmental factors, particularly the safety of the disposal of used fuels, should be taken into consideration when deriving 'allowable' impurity limits for nuclear fuel materials.

    1999-01-01

    Industrial ecology may be a relatively new concept -- yet it`s already proven instrumental for solving a wide variety of problems involving pollution and hazardous waste, especially where available material resources have been limited. By treating industrial systems in a manner that parallels ecological systems in nature, industrial ecology provides a substantial addition to the technologies of environmental chemistry. Stanley E. Manahan, bestselling author of many environmental chemistry books for Lewis Publishers, now examines Industrial Ecology: Environmental Chemistry and Hazardous Waste. His study of this innovative technology uses an overall framework of industrial ecology to cover hazardous wastes from an environmental chemistry perspective. Chapters one to seven focus on how industrial ecology relates to environmental science and technology, with consideration of the anthrosphere as one of five major environmental spheres. Subsequent chapters deal specifically with hazardous substances and hazardous waste, as they relate to industrial ecology and environmental chemistry.

    Asymmetric flow field-flow fractionation (AF4) coupled with dynamic light scattering or multiangle light scattering detectors is a promising technique for the size-based separation of colloidal particles (nano- and submicron scale) and the online determination of the particle size of the separated fractions in aqueous suspensions. In most cases, the applications of these detectors are problematic due to the material-specific properties of the analyte that results in erroneous calculations, and as an alternative, different nanoparticle size standards are required to properly calibrate the size-based retention in AF4. The availability of nanoparticle size standards in different materials is limited, and this deviation from ideal conditions of retention is mainly due to material-specific and particle coating-specific membrane–particle interactions. Here, we present an experimental method on the applicability of polystyrene nanoparticles (PS NP) as standard for AF4 calibration and compare with gold nanoparticle (Au NP) standards having different nominal sizes and surface functionalities.

    Research groups and the food and pharmaceutical industries recognize edible packaging as a useful alternative or addition to conventional packaging to reduce waste and to create novel applications for improving product stability, quality, safety, variety, and convenience for consumers. Recent studies have explored the ability of biopolymer-based food packaging materials to carry and control-release active compounds. As diverse edible packaging materials derived from various by-products or waste from food industry are being developed, the dry thermoplastic process is advancing rapidly as a feasible commercial edible packaging manufacturing process. The employment of nanocomposite concepts to edible packaging materials promises to improve barrier and mechanical properties and facilitate effective incorporation of bioactive ingredients and other designed functions. In addition to the need for a more fundamental understanding to enable design to desired specifications, edible packaging has to overcome challenges such as regulatory requirements, consumer acceptance, and scaling-up research concepts to commercial applications.

    Iceland and Trinidad and Tobago are small open, high-income island economies with very specific resource-use patterns. This article presents a material flow analysis (MFA) for the two countries covering a time period of nearly five decades. Both countries have a narrow domestic resource base, their economy being largely based on the exploitation of one or two key resources for export production. In the case of Trinidad and Tobago, the physical economy is dominated by oil and natural gas extraction and petrochemical industries, whereas Iceland's economy for centuries has been based on fisheries. More recently, abundant hydropower and geothermal heat were the basis for the establishment of large export-oriented metal processing industries, which fully depend on imported raw materials and make use of domestic renewable electricity. Both countries are highly dependent on these natural resources and vulnerable to overexploitation and price developments. We show how the export-oriented industries lead to high and growing levels of per capita material and energy use and carbon dioxide emissions resulting from large amounts of processing wastes and energy consumption in production processes. The example of small open economies with an industrial production system focused on few, but abundant, key resources and of comparatively low complexity provides interesting insights of how resource endowment paired with availability or absence of infrastructure and specific institutional arrangements drives domestic resource-use patterns. This also contributes to a better understanding and interpretation of MFA indicators, such as domestic material consumption.

    The methods of Integrated Computational Materials Engineering that were developed and successfully applied for Aluminium have been constantly improved. The main aspects and recent advances of integrated material and process modeling are simulations of material properties like strength and forming properties and for the specific microstructure evolution during processing (rolling, extrusion, annealing) under the influence of material constitution and process variations through the production process down to the final application. Examples are discussed for the through-process simulation of microstructures and related properties of Aluminium sheet, including DC ingot casting, pre-heating and homogenization, hot and cold rolling, final annealing. New results are included of simulation solution annealing and age hardening of 6xxx alloys for automotive applications. Physically based quantitative descriptions and computer assisted evaluation methods are new ICME methods of integrating new simulation tools also for customer applications, like heat affected zones in welding of age hardening alloys. The aspects of estimating the effect of specific elements due to growing recycling volumes requested also for high end Aluminium products are also discussed, being of special interest in the Aluminium producing industries.

    Industry with an activity of processing natural resources from crust of earth as raw materials could cause natural radioactivity in crust of earth to be accumulated in waste, by product and or main product of that industry. Natural radioactive elements which are mobilized and then accumulated in end industry process are known as NORM (Naturally Occurring Radioactive Materials). NORM have a potential radiological impact such as external and internal radiation exposure. Therefore, the existence of NORM in these non-nuclear industries should be studied in order to handle properly the radiological impact of those material to the industrial workers, member of the public and the surrounding environment. This paper describes the non nuclear industrial sectors in Indonesia that have potential NORM sources and radiation safety aspects in connecting with NORM. (author)

    A material analysis beamline for the industrial enterprises' use was completed at BL-5 of NewSUBARU synchrotron radiation facility in University of Hyogo in March 2008. BL-5 consists of two branch lines, one is a double crystal monochromator beamline (BL-5A) for the use in the higher-energy region (1300-4000 eV) and the other is a varied line spacing plane grating (VLSPG) monochromator beamline (BL-5B) for the use in the lower-energy region (50-1300 eV). These two branch lines can be operated simultaneously. BL-5 covers the soft X-ray region from 50 to 4000 eV and X-ray absorption spectrum can be measured with a high-energy resolution. The XAFS measurements in the total electron yield (TEY) and fluorescence yield (FLY) can be performed at BL-5A and BL-5B. In addition, the XPS spectra can be measured at BL-5B. BL-5 will be managed and maintained by the Synchrotron Analysis L.L.C. (SALLC), which is composed of the industrial companies, in cooperation with the staffs of the Laboratory of Advanced Science and Technology for Industry in University of Hyogo. Industrial users can be assisted by staffs of SALLC in the measurement at BL-5. (author)

    The concept of in-line sputtering and selenization become industrial standard for Cu-III-VI 2 solar cell fabrication, but still it's very difficult to control and predict the optical and electrical parameters, which are closely related to the chemical composition distribution of the thin film. The present review article addresses onto the material design, device design and process design using parameters closely related to the chemical compositions. Its variation leads to change in the Poisson equation, current equation, and continuity equation governing the device design. To make the device design much realistic and meaningful, we need to build a model that relates the opto-electrical properties to the chemical composition. The material parameters as well as device structural parameters are loaded into the process simulation to give a complete set of process control parameters. The neutral defect concentrations of non-stoichiometric CuMSe 2 (M = In and Ga) have been calculated under the specific atomic chemical potential conditions using this methodology. The optical and electrical properties have also been investigated for the development of a full-function analytical solar cell simulator. The future prospects regarding the development of copper-indium-gallium-selenide thin film solar cells have also been discussed.

    The packaging materials industry has already recognized the importance of Total Productive Maintenance as a system of proactive techniques for improving equipment reliability. Bearing faults, which often occur gradually, represent one of the foremost causes of failures in the industry. Therefore, detection of their faults in an early stage is quite important to assure reliable and efficient operation. We present a new automated technique for early fault detection and diagnosis in rolling-element bearings based on vibration signal analysis. Following the wavelet decomposition of vibration signals into a few sub-bands of interest, the standard deviation of obtained wavelet coefficients is extracted as a representative feature. Then, the feature space dimension is optimally reduced to two using scatter matrices. In the reduced two-dimensional feature space the fault detection and diagnosis is carried out by quadratic classifiers. Accuracy of the technique has been tested on four classes of the recorded vibrations signals, i.e., normal, with the fault of inner race, outer race, and ball operation. The overall accuracy of 98.9% has been achieved. The new technique can be used to support maintenance decision-making processes and, thus, to increase reliability and efficiency in the industry by preventing unexpected faulty operation of bearings.

    Republic of Macedonia, as many European countries, possesses great quantities of industrial waste materials from thermo electrical power stations and metallurgical capacities. The powder from waste fly ash and metallurgical slag was specified from chemical, geometrical, structural and thermochemical aspects. After the consolidation, the compacts were specified from structural, mechanical and thermophysical aspects. Using three kinds of waste glasses (TV glass, window and flask), the sintering temperature was significantly reduced and ecologically risky components were fixed molecularly in the matrix based on fly ash and metallurgical slag. The glass was characterized from chemical, geometrical and thermophysical point of view. The amount of glass in the composites varied from 10%-50%. The mechanical and thermal expansion properties of the sintered compacts, in the temperature region from 800 o -1200 o C were determined. The thermodynamic stability, mechanical properties and chemical inertness have been used as criterion for selection of the consolidated compacts. Special attention was given to the creation of highly porous structure. For the purpose to obtain a high joint porous structure, several types of porosity have been used: polyurethane foam, hydrogen peroxide, limestone, carbon ash and carbon fibres. The obtained glass-ceramic materials could be used in the building industry, for making filters for gases and liquids as well as diffusers for waste water aeration. (Author)

    The industry of the iron and the steel in one of the most important sectors in Spain for its economic development. the recycling of metallic materials as well as the import of metallic scrap is very significant. Several reports on accidental dispersion or smelting of radioactive sources in metal recycling industries confirm the possibility that radioactive material might be mixed with scrap. In consequence, this type of accident shows the necessity of a rigorous and specific radiation control of the sector. The control of these materials with radioactive content can be carried out with radiation portal monitors installed at the entrance of these industries. The detection of radioactive materials presents special features as the continuous background acquisition or the minimisation of the relatively large number of innocent/nuisance detections. In the present work, we study a radiation portal monitor, the FHT-1388-T Thermo-Eberline. This is one of the usual radiation portal systems installed at the entrance of the metal recycling industry. Se study the characteristics and parameters of this portal monitor to optimise its use. furthermore, we propose some rapid tests for radiation portal systems in metal recycling industry.

    Metallic, ceramic, and organic coatings are so commonly used in modern industry that virtually everyone can name several applications in which coatings are employed. Thus, it is no surprise that coating technologies are widely employed in the nuclear industry. Some of these technologies utilize processes that are mature and well developed, and others utilize processes that are new and state of the art. In this paper, five generic coating processes that include almost all vapor deposition processes are described, and then applications of each of these processes for deposition of specific materials in nuclear applications are described. These latter selections, of course, are very subjective, and others will be able to name other applications. Because of their wide range of application, coating technologies are considered to be national critical technologies. The generic coating processes that cover almost all vapor deposition technologies are as follows: (1) stationary substrate chemical vapor deposition; (2) fluidized bed chemical vapor deposition; (3) plasma-assisted chemical deposition; (4) sputtering; (5) evaporation

    Full Text Available The study of start-ups, have remained largely a micro economic issue. Firms are the key drivers of industrial sector GDP (or enterprise growth in countries across regions. Few studies have tried to examine the consequence of start-ups in the broad macroeconomics terms on enterprise growth in general with special emphasis on industrial sector output. This study provides a macroeconomic study of the effect of start- ups on industrial sector growth for countries in some specific geographical regions of the world. Panel data is utilized due to it obvious advantages such its ability to utilize a panel of short time frames and its suitability for controlling for omitted variable bias and unobservable heterogeneity across regions. The results show that start-ups remain an intrinsic variable for enterprise growth and industrial sector output discussion in general.

    The concept of in‐line sputtering and selenization become industrial standard for Cu–III–VI2 solar cell fabrication, but still it's very difficult to control and predict the optical and electrical parameters, which are closely related to the chemical composition distribution of the thin film. The present review article addresses onto the material design, device design and process design using parameters closely related to the chemical compositions. Its variation leads to change in the Poisson equation, current equation, and continuity equation governing the device design. To make the device design much realistic and meaningful, we need to build a model that relates the opto‐electrical properties to the chemical composition. The material parameters as well as device structural parameters are loaded into the process simulation to give a complete set of process control parameters. The neutral defect concentrations of non‐stoichiometric CuMSe2 (M = In and Ga) have been calculated under the specific atomic chemical potential conditions using this methodology. The optical and electrical properties have also been investigated for the development of a full‐function analytical solar cell simulator. The future prospects regarding the development of copper–indium–gallium–selenide thin film solar cells have also been discussed. PMID:27840790

  10. Phosphogypsum recycling in the building materials industry: assessment of the radon exhalation rate.

    Science.gov (United States)

    Campos, M P; Costa, L J P; Nisti, M B; Mazzilli, B P

    2017-06-01

    Phosphogypsum can be classified as a Naturally Occurring Radioactive Material (NORM) residue of the phosphate fertilizer industry. One of the main environmental concerns of its use as building material is the radon exhalation. The aim of this study is to measure the radon exhalation rate from plates and bricks manufactured with phosphogypsum from three installations of the main Brazilian producer, Vale Fertilizantes, in order to evaluate the additional health risk to dwellers. A simple and reliable accumulator method involving a PVC pipe sealed with a PVC pipe cover commercially available with CR-39 radon detector into a diffusion chamber was used for measuring radon exhalation rate from phosphogypsum made plates and bricks. The radon exhalation rate from plates varied from 0.19 ± 0.06 Bq m -2 h -1 , for phosphogypsum from Bunge Fertilizers, from 1.3 ± 0.3 Bq m -2 h -1 , for phosphogypsum from Ultrafertil. As for the bricks, the results ranged from 0.11 ± 0.01 Bq m -2 h -1 , for phosphogypsum from Bunge Fertilizers, to 1.2 ± 0.3 Bq m -2 h -1 , for phosphogypsum from Ultrafertil. The results obtained in this study for the radon exhalation rate from phosphogypsum plates and bricks are of the same order of magnitude than those from ordinary building materials. So, it can be concluded that the recycling of phosphogypsum as building material is a safe practice, since no additional health risk is expected from the radiological point of view.

  12. Exposure to radiation from the natural radioactivity in building materials

    International Nuclear Information System (INIS)

    1979-05-01

    Radiation exposure of members of the public can be increased appreciably by the use of building materials containing above-normal levels of natural radioactivity. This phenomenon has attracted attention in recent years, and in this review, an attempt is made to the quantify exposures incurred under various circumstances. The second section of the review is a general survey of those building materials, mostly industrial wastes, that have aroused interest in Member countries. The probability that environmental pressures may cause such wastes to be used more and more by building industries may lead to similar situations in the future. Other review material of a relevant nature is described in the third section. Primordial radionuclides only are considered here. They are: potassium-40 (K-40); radium-226 (Ra-226) and its decay products; the series headed by thorium-232 (Th-232). The important radiological consequences of the natural radioactivity in building materials are two-fold, irradiation of the body by gamma rays and irradiation of the lung tissues by radon-222 (Rn-222) decay products or daughters. These consequences cannot be explored quantitatively except in relation to the specific activities of the nuclides of interest, and the approach adopted in this review is to assess the consequences in terms of the incremental radiation exposures that would be incurred by occupants of substantial dwellings entirely constructed of materials with various specific activities or combinations thereof. Gamma rays are dealt with in the fourth section and radon daughters in the fifth

    Højlund-Nielsen, Emil; Kristensen, Anders

    This doctoral thesis describes the utilization of color metasurfaces in an industrial perspective, where nano-scale textures and contingent post processing replace inks, dyes and pigments in plastic production. The concept of colors by structure arguably reduces the number of raw materials......, exemplified in silicon. However, only corresponding faint colors appear in polymeric materials. The concept of all-polymer pigment-free coloration seems somewhat restricted in relation to widespread industrial employment. Finally, a novel plasmon color technology for structural coloration in plastics......, and it is shown that the dependence on polarization can be controlled. In collaboration with industry, polymer-based colored metasurfaces of square-centimeter size are demonstrated by embossing, injection molding, roll-to-roll printing, and film insert molding with full compatibility.

    Pyrite cinders, which are the waste products of sulphuric acid manufacturing plants, contain hazardous heavy metals with potential environmental risks for disposal. In this study, the potential use of pyrite cinders (PyCs) as iron source in the production of Portland cement clinker was demonstrated at the industrial scale. The chemical and mineralogical analyses of the PyC sample used in this study have revealed that it is essentially a suitable raw material for use as iron source since it contains >87% Fe(2)O(3) mainly in the form of hematite (Fe(2)O(3)) and magnetite (Fe(3)O(4)). The samples of the clinkers produced from PyC in the industrial scale trial operation of 6 months were tested for the conformity of their chemical composition and the physico-mechanical performance of the resultant cement products. The data were compared with the clinker products of the iron ore, which is used as the raw material for the production Portland cement clinker in the plant. The chemical compositions of all the clinker products of PyC appeared to conform to those of the iron ore clinker, and hence, a Portland cement clinker. The mechanical performance of the mortars prepared from the PyC clinker was found to be consistent with those of the industrial cements e.g. CEM I type cements. It can be inferred from the leachability tests (TCLP and SPLP) that PyC could be a potential source of heavy metal pollution while the mortar samples obtained from the PyC clinkers present no environmental problems. These findings suggest that the waste pyrite cinders can be readily used as iron source for the production of Portland cement. The availability of PyC in large quantities at low cost provides further significant benefits for the management/environmental practices of these wastes and for the reduction of mining and processing costs of cement raw materials.

    1988-01-01

    The nuclear industry has extensive radiological emergency planning (REP) experience that is directly applicable to hazardous materials emergency planning. Recently, the Feed Materials Production Center near Cincinnati, Ohio, successfully demonstrated such application. The REP experience includes conceptual bases and standards for developing plans that have been tested in hundreds of full-scale exercises. The exercise program itself is also well developed. Systematic consideration of the differences between chemical and radiological hazards shows that relatively minor changes to the REP bases and standards are necessary. Conduct of full-scale, REP-type exercises serves to test the plans, provide training, and engender confidence and credibility

    2008-08-01

    Full Text Available Mesoporous silicas, especially those exhibiting ordered pore systems and uniform pore diameters, have shown great potential for sensing applications in recent years. Morphological control grants them versatility in the method of deployment whether as bulk powders, monoliths, thin films, or embedded in coatings. High surface areas and pore sizes greater than 2 nm make them effective as adsorbent coatings for humidity sensors. The pore networks also provide the potential for immobilization of enzymes within the materials. Functionalization of materials by silane grafting or through cocondensation of silicate precursors can be used to provide mesoporous materials with a variety of fluorescent probes as well as surface properties that aid in selective detection of specific analytes. This review will illustrate how mesoporous silicas have been applied to sensing changes in relative humidity, changes in pH, metal cations, toxic industrial compounds, volatile organic compounds, small molecules and ions, nitroenergetic compounds, and biologically relevant molecules.

    Hurricane Katrina struck an area dense with industry, causing numerous releases of petroleum and hazardous materials. This study integrates information from a number of sources to describe the frequency, causes, and effects of these releases in order to inform analysis of risk from future hurricanes. Over 200 onshore releases of hazardous chemicals, petroleum, or natural gas were reported. Storm surge was responsible for the majority of petroleum releases and failure of storage tanks was the most common mechanism of release. Of the smaller number of hazardous chemical releases reported, many were associated with flaring from plant startup, shutdown, or process upset. In areas impacted by storm surge, 10% of the facilities within the Risk Management Plan (RMP) and Toxic Release Inventory (TRI) databases and 28% of SIC 1311 facilities experienced accidental releases. In areas subject only to hurricane strength winds, a lower fraction (1% of RMP and TRI and 10% of SIC 1311 facilities) experienced a release while 1% of all facility types reported a release in areas that experienced tropical storm strength winds. Of industrial facilities surveyed, more experienced indirect disruptions such as displacement of workers, loss of electricity and communication systems, and difficulty acquiring supplies and contractors for operations or reconstruction (55%), than experienced releases. To reduce the risk of hazardous material releases and speed the return to normal operations under these difficult conditions, greater attention should be devoted to risk-based facility design and improved prevention and response planning.

    2012-01-01

    End-users and OEM's using or manufacturing on/off and control valves expect a permanent and effective increase in service life together with an increased sealing capability while at the same time minimizing maintenance concerns. Developing materials which provide consistency and repeatability are essential characteristics to optimizing valve performance. “New Generation” materials and yarn allow us to meet this growing demand while complying with the requirements related to chemical purity and an increased level of safety to both plant workers and equipment in the nuclear environment. Through R&D initiatives and developments in new and improved raw materials; a new mechanical packing generation which optimizes friction coefficients and extended life cycle has been introduced to the industry. Lower friction values drastically optimize actuator effort and size improving efficiency for stem operation with significant improvements in flow control of fluids. Combined with new and improved procedures (installation, torque levels and consolidation recommendations), this new packing generation has provided significant improvement in the mechanical behavior of packing materials (independent tests carried out in collaboration with AECL and CETIM) this has provided the opportunity to develop successful Valve Enhancement Programs which offer improved efficiency, valve operation and repeatability. These NEW generation yarns are available with or without wire reinforcement depending on specific operating parameters and conditions. The purpose of this presentation is to demonstrate that new generation material(s). Which are available to the industry for AOV, MOV and Manual valves? - To highlight the steps taken in R&D and manufacturing contributing to the much improved yarns and finished packing products. - Comply and are designed to meet the stringent requirements in the nuclear industry - Simplify valve maintenance without risk to safety or performance - Increase service

    In the present paper the potentials of native tuber crops for the production of raw material for the industry are discussed and the first results presented. The following points are especially important: Based on their high yield potential the potato and the Jerusalem artichoke are especially valuable as industrial crops. First breeding results with potato show that improvements in tuber yield, which are necessary for a better competitive ability are possible. To what extent hybrids between our cultivated potato and different primitive forms can be used as industrial potatoes has to be tested. In order to reduce production input the resistance against nematodes and lade blight is most important for the production of basic populations of potatoes for industrial purposes. The succes of breeding Jerusalem artichoke depends on solving the problems of bad seed set.

    This investigation has been made in order to make it possible to increase the use of by-products in cement-based materials. Use of by-products requires a screening procedure that will reliably determine their impact on concrete. A test procedure was developed. The most important properties were considered to be strength development, shrinkage, expansion and workability. The methods used were calorimetry, flow table tests, F-shape measurements, measurements of compressive and flexural strength and shrinkage/expansion measurements. Scanning electron microscopy was used to verify some results. Twelve by-products were collected from Swedish metallurgical and mineral industries and classified according to the test procedure. The investigation showed that the test procedure clearly screened out the materials that can be used in the production of concrete from the unsuitable ones.

    The process industries, in particular the petroleum refining industry, adopted materials engineering and inspection (ME and I) practices years ago and regularly updated them because they were faced with the handling and refining of flammable, toxic, and corrosive feed stocks. These industries have a number of nonproprietary techniques and procedures, some of which may be applicable in the nuclear power generation field. Some specific inspection and engineering techniques used by the process industries within the framework of the guidelines for inspections and worthy of detailed description include the following: (1) sentry drilling or safety drilling of piping subject to relatively uniform corrosion, such as feedwater heater piping, steam piping, and extraction steam piping; (2) on-stream radiography for thickness measurement and detection of unusual conditions - damaged equipment such as valve blockage; (3) critical analysis of the chemical and refining processes for the relative probability of corrosion; (4) communication of valuable experience within the industry; (5) on-stream ultrasonic thickness testing; and (6) on-stream and off-stream crack and flaw detection. The author, trained in the petroleum refining industry but versed in electric utilities, pulp and paper, chemical process, marine, mining, water handling, waste treatment, and geothermal processes, discusses individual practices of these various industries in the paper

    Mrnustik, J.

    1988-01-01

    Within a study of the natural radioactivity of building materials, coefficients were determined of the emanation from selected materials and raw materials, such as porous concrete, bricks, marlite, quartzite, etc. Measurements were made of ground samples using Lucas scintillation chambers which give an accuracy of determination of the coefficient of about 10%. Specific radium activity was also determined for the samples. Tabulated is a comparison of the average specific activity of radium in concrete, power plant ash and porous concrete in Czechoslovakia and abroad. It is stated that monitoring the content of natural radionuclides in building materials is an indispensable part of the production process in the building industry, this with regard to the radiation protection of the population. This will be enhanced by the new Czechoslovak standard determining methods of measuring the content of natural radionuclides and the coefficient of radon emanation, and the subsequent evaluation of the properties of building materials.

    This paper gives an insight of biofuel production and the status -into the co-products obtained from this industry. Furthermore this work explores the possibility of these co-products as raw materials for value-added uses in material applications. This is achieved by understanding composition, solid density, and moisture content of prominent co-products such as soy meal, DDGS (distillers’ dried grains with solubles) and jatropha meal. Moisture content and density measurements showed no trend. Soy meal has the highest protein content, followed by jatropha and DDGS. Thermal stability of these co-products was analyzed by thermogravimetric analysis (TGA), which revealed that the thermal stabilities are ranked as soy meal>DDGS>jatropha meal. FT-IR spectroscopy was used to understand the functional groups in these meals and it showed that the amide group was prominent in all of these meals. In pursuit of finding value-added uses for these co-products of biofuel industries, biodegradable polymer, i.e. polycaprolactone (PCL), based biocomposites were prepared by melt processing technique using extrusion followed by injection molding. Tensile, flexural and impact properties were evaluated. Also, scanning electron microscopy (SEM) of fractured sections of the biocomposites was examined. -- Highlights: ► This paper gives an insight of biofuel production and its co-products. ► We have characterized biofuel co-products such as soy meal, DDGS and jatropha meal. ► Thermal stability and functional groups of these co-products were determined. ► Polycaprolactone based biocomposites were prepared by melt processing technique. ► Tensile, flexural and impact properties of these biocomposites were evaluated.

    A rich theoretical background to the problems that occur in the automation of material handling can be found in operations research, production engineering, systems engineering and automation, more specifically machine vision, literature. This work has contributed towards the design of intelligent handling systems. This paper will review the application of these automated material handling and packing techniques to industrial problems. The discussion will also highlight the systems integration issues involved in these applications. An outline of one such industrial application, the automated placement of shape templates on to leather hides, is also discussed. The purpose of this system is to arrange shape templates on a leather hide in an efficient manner, so as to minimize the leather waste, before they are automatically cut from the hide. These pieces are used in the furniture and car manufacturing industries for the upholstery of high quality leather chairs and car seats. Currently this type of operation is semi-automated. The paper will outline the problems involved in the full automation of such a procedure.

    Full Text Available The article examines the main stages of the financial-industrial groups formation in Russia in the 1990s, analyzes the main premises of these forms of association in the industrial and financial sectors, as well as the mechanism of their creation under conditions of the transitional market economy. The study revealed the main forms of financial and industrial groups in Russia and the fact that they had a national specificity. The author concludes that the distinctive feature was the formation of Russian business groups mostly from the former nomenklatura and Komsomol workers on the basis of pre-existing material base, which largely contributed to their rapid transformation into large concerns. The state did not prevent the creation of industrial and financial corporations, because of receiving financial support in the form of replenishment of the state budget through tax revenues and revival of production through investments in illiquid corporate enterprises.

    1983-06-01

    Past energy-consumption trends and future energy-conservation opportunities are investigated for the nation's iron and steel industry. It is estimated that, in 1980, the industry directly consumed approximately 2.46 x 10/sup 15/ Btu of energy (roughly 3% of total US energy consumption) to produce 111 million tons of raw steel and to ship 84 million tons of steel products. Direct plus indirect consumption is estimated to be about 3.1 x 10/sup 15/ Btu. Of the set of conservation technologies identified, most are judged to be ready for commercialization if and when the industry's capital formation and profitability problems are solved and the gradual predicted increase in energy prices reduces the payback periods to acceptable levels.

    2017-07-01

    Non-hazardous solid materials from industrial processes, once regarded as waste and disposed in landfills, offer numerous environmental and economic advantages when put to beneficial uses (BUs). Proper management of these industrial non-hazardous secondary materials (INSM) requires estimates of their probable environmental impacts among disposal as well as BU options. The U.S. Environmental Protection Agency (EPA) has recently approved new analytical methods (EPA Methods 1313-1316) to assess leachability of constituents of potential concern in these materials. These new methods are more realistic for many disposal and BU options than historical methods, such as the toxicity characteristic leaching protocol. Experimental data from these new methods are used to parameterize a chemical fate and transport (F&T) model to simulate long-term environmental releases from flue gas desulfurization gypsum (FGDG) when disposed of in an industrial landfill or beneficially used as an agricultural soil amendment. The F&T model is also coupled with optimization algorithms, the Beneficial Use Decision Support System (BUDSS), under development by EPA to enhance INSM management. Published by Elsevier Ltd.

    Presently, appropriate waste management is one of the main requisites for sustainable development; this task is tackled by the material construction industry. The work described herein is focused on the valorization of granite waste through incorporation, as a filler-functional admixture, into cement-based mortar formulations. The main components of the waste are SiO(2) (62.1 %), Al(2)O(3) (13.2 %), Fe(2)O(3) (10.1 %), and CaO (4.6 %). The presence of iron oxides is used to develop the photocatalytic properties of the waste. Following heating at 700 °C, α-Fe(2)O(3) forms in the waste. The inclusion of the heated sample as a filler admixture in a cement-based mortar is possible. Moreover, this sample exhibits a moderate ability in the photodegradation of organic dye solutions. Also, the plastering mortars, in which the heated samples have been used, show self-cleaning properties. The preparation of sustainable building materials is demonstrated through the adequate reuse of the granite waste. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  16. Network Traffic Features for Anomaly Detection in Specific Industrial Control System Network

    2013-09-01

    Full Text Available The deterministic and restricted nature of industrial control system networks sets them apart from more open networks, such as local area networks in office environments. This improves the usability of network security, monitoring approaches that would be less feasible in more open environments. One of such approaches is machine learning based anomaly detection. Without proper customization for the special requirements of the industrial control system network environment, many existing anomaly or misuse detection systems will perform sub-optimally. A machine learning based approach could reduce the amount of manual customization required for different industrial control system networks. In this paper we analyze a possible set of features to be used in a machine learning based anomaly detection system in the real world industrial control system network environment under investigation. The network under investigation is represented by architectural drawing and results derived from network trace analysis. The network trace is captured from a live running industrial process control network and includes both control data and the data flowing between the control network and the office network. We limit the investigation to the IP traffic in the traces.

    Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of the natural radionuclide in zirconium industry is described. Materials and Methods: Gamma spectrometry system with a shielded high pure germanium (HPGe) detector connected to multi channel analyzer (MCA) was used to determine concentrations of natural radionuclide in about 45 samples of imported zirconium minerals, tiles, stone ware and waste sludge's of Iranian ceramic industry. Results: The 238 U concentration in the samples, ranging from 3000 to 10000 Bq Kg -1 , is higher than the concentration of both 232 Th (500-1800 Bq Kg -1 ), and 40 K (50-800 Bq Kg -1 ). The measured specific activities in the mineral showed that specific activity of baddeleyite is higher than that of zircon. The results of ceramic tiles show that the tiles usually contain small amount of zirconium compound. Conclusion: Due to relatively high concentration level of uranium in imported zirconium samples, specific regulations is necessary for zirconium compound used in ceramic industry

    By using waste materials as alternative fuels in metallurgical plants it is possible to minimize the traditionally used reducing agents, such as coke, coal, oil or natural gas. Moreover, by using waste materials in the metallurgical industry it is feasible to recover these materials as far as possible. This also represents another step towards environmental protection because carbon dioxide emissions can be reduced, if the H(2) content of the waste material is greater in comparison with that of the substituted fuel and the effects of global warming can therefore be reduced. In the present article various solid recovered fuels and their applications in the metallurgical industry are detailed.

    Natural raw materials should be understood as highly refined chemicals ready for derivatization rather than degradation through fermentation. Chemistry and agriculture have had a long connection in the manufacturing of fibres, paints, glues, and soaps when natural raw materials were supplied by agricultural production. With the detection of crude oil as a chemical raw material, this connection seemed to fall apart. After the energy crises of 1973 and 1979, the 'oil shocks', a revival of interest in renewable raw materials was triggered. Only 10% of all the raw materials used by the organic chemical industry represents renewable resources. The chemical industry is developing new markets for such resources. In most cases these raw materials come from developing countries. Agriculture in industrialized nations is asked to match these developments through intensive research in the areas of agronomy and plant breeding. Examples of such new raw materials which are discussed include high oleic sunflower oil, Euphorbia lathyris (spurge) oil, Cuphea oil, high erucic rapeseed oil, Crambe and mustard oil, meadowfoam and coriander oil. The agricultural production of such custom tailored industrial raw materials could become a new outlet for industrialized countries' agriculture, which today is characterized by a surplus production of food.

    This handbook comprises the common practices of the Swedish nuclear industry for the clearance of material, rooms, buildings and soil in order to be exempted from the Swedish Nuclear Activities Act and the Swedish Radiation Protection Act. After clearance the management/usage of material, rooms, buildings and soil is permitted without any control from the radiation protection point of view. Clearance is practiced to reduce the amount radioactive waste. Cleared material can be reused according to its original form, recycled or, if these two possibilities are not available, disposed as conventional waste. The working procedures described in this handbook are mainly based on the regulation SSMFS 2011:2 from the Swedish Radiation Safety Authority: 'Regulations concerning clearance of material, rooms, buildings and soil from activities with ionising radiation'. The purpose of this handbook is to serve as a tool and guidance for generating specific routines and instructions for clearance. It describes the principles, processes and routines that should be followed under a clearance procedure. The intention is to accomplish the current regulation by following the routines and principles described in this manual. This handbook spans over a large number of conditions towards clearance, such as facility specific conditions and different types of objects. Because not all the conceivable conditions and objects can be included here, the purpose has been to cover the most common types of clearance practices. The practices comprise: - Description of regulations and recommendations, Swedish and international, that represent the basis of the requirements in this handbook. - Presentation of the processes for clearance of material, rooms, buildings and soil. Those which cannot be cleared are considered as radioactive waste. A proposal for the decision-making process is presented. - Illustration for radiological surveys to systems and components, buildings and soil in regard

    Industrial ecology incorporates ecological theories, functions and limits into the design of industrial production systems, processes and products. The main objective is to enhance environmental and economic performance through collaboration in managing environmental resource issues such as energy, water and materials. Industrial ecology recognizes the connectedness and synergies of materials, products and infrastructure. As such, it considers the life cycle of products, the design of buildings, infrastructure and industrial parks. By working together, businesses gain a collective benefit which is greater than the total of the individual benefits each company could achieve on its own. Industrial ecology also considers the reuse, recovery and recycling of resources. The benefits include: efficiency of resource use; cost reduction for industrial infrastructure; sustainable development support; and, new opportunities in economic development, technology development, manufacturing, and business management. This primer also presents guidelines for win-win projects in industrial ecology. refs., figs.

    The hydrothermal carbonization (HTC) is a chemicalphysical process wherein the biomass of vegetal origin is converted into a lignite-like material. Only a few hours in an aqueous suspension at temperatures of 180-250 C and under pressure are needed for the transformation. Because of these reaction conditions highly aqueous wastes and residues are well suited materials for the HTC-process. The high calorific values of HTC Biochar enable efficient energy use of primary materials. A basic advantage is seen in the excellent dewatering properties of these biocoals. As part of an ongoing project by the BMBF a semi-industrial scale system was developed (200 liters) by the authors. There the HTC process is examined in a continuous process. After a description of the basic process concept first results of the continuous process are presented. These are compared with previous laboratory results on the example of organic industrial wastes. Further detailed results of continuous carbonization of sewage sludge and flanking batch studies are presented. The final issues to be worked on in the technical implementation are the specific energy consumption of the conversion and its potential for optimization. (orig.)

    India is bestowed with vast livestock wealth and it is growing at the rate of 6% per annum. The contribution of livestock industry including poultry and fish is increasing substantially in GDP of country which accounts for >40% of total agricultural sector and >12% of GDP. This contribution would have been much greater had the animal by-products been also efficiently utilized. Efficient utilization of by-products has direct impact on the economy and environmental pollution of the country. Non-utilization or under utilization of by-products not only lead to loss of potential revenues but also lead to the added and increasing cost of disposal of these products. Non-utilization of animal by-products in a proper way may create major aesthetic and catastrophic health problems. Besides pollution and hazard aspects, in many cases meat, poultry and fish processing wastes have a potential for recycling raw materials or for conversion into useful products of higher value. Traditions, culture and religion are often important when a meat by-product is being utilized for food. Regulatory requirements are also important because many countries restrict the use of meat by-products for reasons of food safety and quality. By-products such as blood, liver, lung, kidney, brains, spleen and tripe has good nutritive value. Medicinal and pharmaceutical uses of by-product are also highlighted in this review. Waste products from the poultry processing and egg production industries must be efficiently dealt with as the growth of these industries depends largely on waste management. Treated fish waste has found many applications among with which the most important are animal feed, biodiesel/biogas, dietectic products (chitosan), natural pigments (after extraction) and cosmetics (collagen). Available information pertaining to the utilization of by-products and waste materials from meat, poultry and fish and their processing industries has been reviewed here.

    Full Text Available Science and practice proved the high efficiency of granulated mixed fodders. This article presents an overview of granulation technologies for various industries. This article discusses the application of granulation technologies in various industries. The processes of granulation are mass technological processes currently used in a wide range of industries: feed industry, food industry, pharmaceutical industry, fertilizer production, polyethylene, metal production, mining, etc. A wide range of different materials are granulated, including chemicals, iron ore, mixed fodder, and much more. Granulation is a process of pressing or shaping a material in the form of granules.  Granulation is widely used in the production of pigments, dyes, synthetic detergents, catalysts, plastics, soot, chemical reagents, etc. The use of granular raw materials in the metallurgical industry helps not only to mechanize processes, but also to increase their intensity by increasing the contact surface of interacting media. Granular fertilizers retain their properties for a long time. In the mining industry, granulation processes are used at the stage of preparation and enrichment of raw materials and release of the finished product.  Particular attention is paid to the feed industry. Granulation allows to ensure stable homogeneity, to improve sanitary and hygienic parameters, to increase nutritional value, to increase the storage period, improve the physical properties. However, despite all the advantages, the existing granulation production lines have a relatively high productivity and, at the same time, a high energy intensity. In this regard, this article proposes a technology for improving the granulation of mixed fodders. According to a preliminary literary review, It should be concluded that improving the technology of the granulation process for feed production is a topical issue in the feed industry today. The development of technology for improving the

    2016-11-01

    The interesting characteristics of electrospun nanofibres, such as high surface-to-volume ratio, nanoporosity, and high safety, make them suitable candidates for use in a variety of applications. In the recent decade, electrospun nanofibres have been applied to different potential fields such as filtration, wound dressing, drug delivery, etc. and a significant number of review papers have been published in these fields. However, the use of electrospun nanofibres in agriculture is comparatively novel and is still in its infancy. In this paper, the specific applications of electrospun nanofibres in agriculture and food science, including plant protection using pheromone-loaded nanofibres, plant protection using encapsulation of biocontrol agents, preparation of protective clothes for farm workers, encapsulation of agrochemical materials, deoxyribonucleic acid extraction in agricultural research studies, pre-concentration and measurement of pesticides in crops and environmental samples, preparation of nanobiosensors for pesticide detection, encapsulation of food materials, fabrication of food packaging materials, and filtration of beverage products are reviewed and discussed. This paper may help researchers develop the use of electrospun nanofibres in agriculture and food science to address some serious problems such as the intensive use of pesticides. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Water and soil natural radioactivity is a well known phenomenon which can produced by variable concentrations of uranium and thorium series radionuclides. Generally, the relevant radiological hazard is not important; however, some radiation protection problems can occur in particular industrial processes involving the treatment of large quantities of materials. In this case a high concentration of radioactive substance (NORM: nationally occurring radioactive materials) can be found at special points of the plant, in the manufacture by-products and in the waters. Sometimes the national radioactivity concentration can be so high to raise radiation protection problems which can be assimilated in a sense to the ones faced in the presence, handling, and disposal of non-sealed radioactive sources. In this paper the following mining and hydrocarbon extraction plants were particularly taken into account: (a) industries using zircon sands to produce refractory and ceramic materials; (b) phosphorites manufacture to prepare phosphoric acids, plasters and fertilizers (c) hydrocarbon extraction and treatment processes where formations of low specific activity (L.S.A.) scales and sludges are produced. The relevant results and the possible radiation protection risks for the professional exposed staff will be reported. A special emphasis will be given to some african phosphorites (boucraa, togo, morocco), and L.S.A. scales (tunisia, congo, Egypt). 4 figs., 5 tabs.

    Kapoor, Swati; Rafiq, Aasima; Sharma, Savita

    2017-07-24

    Protein engineering is a young discipline that has been branched out from the field of genetic engineering. Protein engineering is based on the available knowledge about the proteins structure/function(s), tools/instruments, software, bioinformatics database, available cloned gene, knowledge about available protein, vectors, recombinant strains and other materials that could lead to change in the protein backbone. Protein produced properly from genetic engineering process means a protein that is able to fold correctly and to do particular function(s) efficiently even after being subjected to engineering practices. Protein is modified through its gene or chemically. However, modification of protein through gene is easier. There is no specific limitation of Protein Engineering tools; any technique that can lead to change the protein constituent of amino acid and result in the modification of protein structure/function is in the frame of Protein Engineering. Meanwhile, there are some common tools used to reach a specific target. More active industrial and pharmaceutical based proteins have been invented by the field of Protein Engineering to introduce new function as well as to change its interaction with surrounding environment. A variety of protein engineering applications have been reported in the literature. These applications range from biocatalysis for food and industry to environmental, medical and nanobiotechnology applications. Successful combinations of various protein engineering methods had led to successful results in food industries and have created a scope to maintain the quality of finished product after processing.

  20. Preparing for a Career in Industrial Physics

    Science.gov (United States)

    Meisner, Gregory

    My career in physics has been extremely rewarding. My career path, however, was not what I imagined it would be when I started college. I thought I would be a math major and eventually a university math professor. A big challenge of my college and graduate school experience, aside from actually learning physics, was to find out what I was most passionate about and then to pursue that endeavor wherever it led. The graduate school part of my career path wound its way into experimental condensed matter physics, but I still expected that I would remain in academia. Along the way, I learned a lot from many people, worked hard to accomplish good results, and availed myself of unexpected opportunities for professional development and career advancement. One piece of advice that resonated with me was to always try to be learning something new, and I did manage to do that throughout my career: in graduate school and as a post doc I studied low temperature experimental physics and superconductivity, whereas my areas of research as an industrial physicist at GM R&D were permanent magnets, then hydrogen storage materials for fuel cell vehicle applications, and finally thermoelectric materials and devices for waste exhaust gas heat recovery. The best piece of advice, which has served me well along my career path and my life path in general, was in the remarks astronaut Katherine Sullivan gave at my PhD graduation ceremony at UCSD in 1982. Her advice was captured in the word ``quality''. Specifically, always strive for the highest quality in everything you do. Another impactful word, which was a favorite of my thesis advisor, Bernd Matthias, is ``serendipity''. Specifically, you need to know how to recognize and capitalize on unexpected or unusual occurrences - they may be the best stepping stones you will have along your career path. My presentation will discuss a few specifics of how I prepared myself for a career in industrial physics.

    1997-09-01

    Titanium is a reference material for the construction of waste containers in the Canadian Nuclear Fuel Waste Management Program. It has been in industrial service for over 30 a, often in severe corrosion environments, but it is still considered a relatively exotic material with limited operating history. This has arisen because of the aerospace applications of this material and the misconception that the high strength-to-weight ratio dominates the choice of this material. In fact, the advantage of titanium lies in its high reliability and excellent corrosion resistance. It has a proven record in seawater heat exchanger service and a demonstrated excellent reliability even in polluted water. For many reasons it is the technically correct choice of material for marine applications. In this report we review the industrial service history of titanium, particularly in hot saline environments, and demonstrate that it is a viable waste container material, based upon this industrial service history and operating experience.

    2016-01-01

    Full Text Available The modern stage of the agro-industrial complex is characterized by an increasing complexity, intensification of technological processes of complex processing of materials of animal origin also the need for a systematic analysis of the variety of determining factors and relationships between them, complexity of the objective function of product quality and severe restrictions on technological regimes. One of the main tasks that face the employees of the enterprises of the agro-industrial complex, which are engaged in processing biotechnological raw materials, is the further organizational improvement of work at all stages of the food chain, besides an increase in the production volume. The meat industry as a part of the agro-industrial complex has to use the biological raw materials with maximum efficiency, while reducing and even eliminating losses at all stages of processing; rationally use raw material when selecting a type of processing products; steadily increase quality, biological and food value of products; broaden the assortment of manufactured products in order to satisfy increasing consumer requirements and extend the market for their realization in the conditions of uncertainty of external environment, due to the uneven receipt of raw materials, variations in its properties and parameters, limited time sales and fluctuations in demand for products. The challenges facing the meat industry cannot be solved without changes to the strategy for scientific and technological development of the industry. To achieve these tasks, it is necessary to use the prediction as a method of constant improvement of all technological processes and their performance under the rational and optimal regimes, while constantly controlling quality of raw material, semi-prepared products and finished products at all stages of the technological processing by the physico-chemical, physico-mechanical (rheological, microbiological and organoleptic methods.

    2009-04-01

    Waste creation in some sectors of the food industry is substantial, and while much of the used material is non-hazardous and biodegradable, it is often poorly dealt with and simply sent to landfill mixed with other types of waste. In this context, overproduction wastes were found in a number of cases to account for 20-40% of the material wastes generated by convenience food manufacturers (such as ready-meals and sandwiches), often simply just to meet the challenging demands placed on the manufacturer due to the short order reaction time provided by the supermarkets. Identifying specific classes of waste helps to minimise their creation, through consideration of what the materials constitute and why they were generated. This paper aims to provide means by which food industry wastes can be identified, and demonstrate these mechanisms through a practical example. The research reported in this paper investigated the various categories of waste and generated three analytical methods for the support of waste minimisation activities by food manufacturers. The waste classifications and analyses are intended to complement existing waste minimisation approaches and are described through consideration of a case study convenience food manufacturer that realised significant financial savings through waste measurement, analysis and reduction.

    One of the trends in construction material science is development and implementation of highly effective finish materials which improve architectural exterior of cities. Silicate materials widely-used in the construction today have rather low decorative properties. Different coloring agents are used in order to produce competitive materials, but due to the peculiarities of the production, process very strict specifications are applied to them. The use of industrial wastes or variety of rock materials as coloring agents is of great interest nowadays. The article shows that clay rock can be used as raw material in production of finish materials of non-autoclaved solidification. This raw material due to its material composition actively interacts with cementing component in steam treatment at 90–95 °C with formation of cementing joints that form a firm coagulative-cristalized and crystallization structure of material providing high physic-mechanical properties of silicate goods. It is determined that energy-saving, colored finish materials with compression strength up to 16 MPa can be produced from clay rocks.

    INGEOMINAS carried out this project in the cities of Cartagena, Bucaramanga, Cali and Bogota, in two phases: Phase 1 (Diagnostic) and Phase II (Formulation of Handling Plan). The phase 1 that here is described, it upgrades the knowledge of the extractive industry of the construction materials for the city of Cartagena, through bibliographical revision and field work, carried out in 50 quarries that supply from these materials to the city. This study, besides the economic and legal handling, identifies technical aspects related with the geology, the mining and the environmental situation. In accordance with their likeness, geologic, morphological and of exploitation (extraction methods and mining development), the quarries met in five groups: Exploitations on calcareous deposits of the La Popa Formation, exploitations on clay deposits of the La Popa Formation, exploitations on detritus deposits of half grain to thick (La Popa-Arenosa Formation; Pendales Conglomerate and Rotinet Formation) and exploitation of calcareous of the Arroyo de Piedra Formation. The extraction of these materials is characterized by its low degree of development technician, lack of planning mining, lack of appropriate infrastructure that allows a better development of the sector, is also evident the control lack on the part of the entities in charge of the handling of this industry. These factors added to a demand every time in increase of these materials, they have taken to a progressive deterioration in the landscape, increase of the noise and particles in the air and in the waters. The low control in this activity has generated the proliferation of informal exploitations that they find in this activity a way of subsistence

    2017-03-01

    Full Text Available Purpose: The purpose of this paper is to investigate the external factors that influence the profitability of a typical Greek systemic bank over the period 2001 – 2014. Design/Methodology/Approach: A conceptual framework incorporating two fundamental groups of const ructs, namely, macroeconomic forces and industry related factors, was developed. Two constructs were examined in the former: GDP growth rate and unemployment rate, whilst two attributes were explored in the latter; the bank's market share, both in terms of deposits and in terms of assets, and the banking market growth, also both in terms of the market's total assets and total deposits. In order to isolate the effects of the ongoing financial crisis, the research was undertaken for two periods, firstly 2001 to 2014 and secondly, the period 2001 - 2011, which excluded the deep recession. Consequently, multiple regression analysis was conducted and linear models were specified by means of OLS. Findings: The empirical analysis revealed that both macroeconomic forces and industry-related factors affect bank profitability. As far as the macroeconomic factors are concerned, unemployment rate has a negative impact, whereas the GDP growth rate has a positive impact on bank profitability. The industry -related factors, rate of growth of the industry's deposits and bank's assets market share have a positive impact on the financial performance of the bank. Finally, the rate of growth of the industry's assets and the bank's deposits market share have a negative effect on bank profitability. Originality/Value: This study reveals the mechanism determining bank profitability over a recent period that includes the financial crisis. Moreover, understanding the impact of macroeconomic forces as well as industry related attributes on bank profitability may enable banks to focus on the most critical factors in their decision process.

  15. Energy Efficiency Improvement and Cost Saving Oportunities for the Concrete Industry

    Energy Technology Data Exchange (ETDEWEB)

    Kermeli, Katerina; Worrell, Ernst; Masanet, Eric

    2011-12-01

    The U.S. concrete industry is the main consumer of U.S.-produced cement. The manufacturing of ready mixed concrete accounts for more than 75% of the U.S. concrete production following the manufacturing of precast concrete and masonry units. The most significant expenditure is the cost of materials accounting for more than 50% of total concrete production costs - cement only accounts for nearly 24%. In 2009, energy costs of the U.S. concrete industry were over $610 million. Hence, energy efficiency improvements along with efficient use of materials without negatively affecting product quality and yield, especially in times of increased fuel and material costs, can significantly reduce production costs and increase competitiveness. The Energy Guide starts with an overview of the U.S. concrete industry’s structure and energy use, a description of the various manufacturing processes, and identification of the major energy consuming areas in the different industry segments. This is followed by a description of general and process related energy- and cost-efficiency measures applicable to the concrete industry. Specific energy and cost savings and a typical payback period are included based on literature and case studies, when available. The Energy Guide intends to provide information on cost reduction opportunities to energy and plant managers in the U.S. concrete industry. Every cost saving opportunity should be assessed carefully prior to implementation in individual plants, as the economics and the potential energy and material savings may differ.

    2015-02-01

    Full Text Available Ethnopedological studies have mainly focused on agricultural land uses and associated practices. Nevertheless, peasant and indigenous populations use soil and land resources for a number of additional purposes, including pottery. In the present study, we describe and analyze folk knowledge related to the use of soils in non-industrial pottery making by peasant potters, in the municipality of Altinho, Pernambuco State, semiarid region at Brazil. Ethnoscientific techniques were used to record local knowledge, with an emphasis on describing the soil materials recognized by the potters, the properties they used to identify those soil materials, and the criteria employed by them to differentiate and relate such materials. The potters recognized three categories of soil materials: “terra” (earth, “barro” (clay and, “piçarro” (soft rock. The multi-layered arrangement of these materials within the soil profiles was similar to the arrangement of the soil horizon described by formal pedologists. “Barro vermelho” (red clay was considered by potters as the principal ceramic resource. The potters followed morphological and utilitarian criteria in distinguishing the different soil materials. Soils from all of these sites were sodium-affected Alfisols and correspond to Typic Albaqualf and Typic Natraqualf in the Soil Taxonomy (Soil Survey Staff, 2010.

    A new marine sediment certified reference material, NMIJ CRM 7306-a, for butyltin and phenyltin analysis has been prepared and certified by the National Metrological Institute of Japan at the National Institute of Advanced Industrial Science and Technology (NMIJ/AIST). Candidate sediment material was collected at a bay near industrial activity in Japan. After air-drying, sieving, and mixing the material was sterilized with {gamma}-ray irradiation. The material was re-mixed and packaged into 250 glass bottles (15 g each) and these were stored in a freezer at -30 C. Certification was performed by use of three different types of species-specific isotope-dilution mass spectrometry (SSID-MS) - SSID-GC-ICP-MS, SSID-GC-MS, and SSID-LC-ICP-MS, with {sup 118}Sn-enriched organotin compounds synthesized from {sup 118}Sn-enriched metal used as a spike. The {sup 118}Sn-enriched mono-butyltin (MBT), dibutyltin (DBT), and tributyltin (TBT) were synthesized as a mixture whereas the {sup 118}Sn-enriched di-phenyltin (DPhT) and triphenyltin (TPhT) were synthesized individually. Four different extraction methods, mechanical shaking, ultrasonic, microwave-assisted, and pressurized liquid extraction, were adopted to avoid possible analytical bias caused by non-quantitative extraction and degradation or inter-conversion of analytes in sample preparations. Tropolone was used as chelating agent in all the extraction methods. Certified values are given for TBT 44{+-}3 {mu}g kg{sup -1} as Sn, DBT 51 {+-} 2 {mu}g kg{sup -1} as Sn, MBT 67 {+-} 3 {mu}g kg{sup -1} as Sn, TPhT 6.9 {+-} 1.2 {mu}g kg{sup -1} as Sn, and DPhT 3.4 {+-} 1.2 {mu}g kg{sup -1} as Sn. These levels are lower than in other sediment CRMs currently available for analysis of organotin compounds. (orig.)

    Concerning naturally occurring radioactive material (NORM) from the oil/ and gas industry most of the industrial countries were lacking clear regulatory frameworks in waste legislation for many years. In the meanwhile on several places in Europe, but also in some of the GCC states in the Middle East such as in the United Arab Emirates and in Oman specialized treatment facilities are either in the stage of construction or already in operation. In particular, pilot plants for the decontamination of NORM-contaminated equipment have been tested recently. The paper reflects on the generation and the technical characterization of NORM but also the legislation compared on international level. Particularly an overview was provided by comparing the common practice on disposal in the North American Countries in comparison to Germany, the UK but also Australia. In addition the successful treatment of produced water from crude oil separation in a ''Constructed Wetland'' in the Sultanate Oman is briefly highlighted.

    Major challenging issues such as climate change, energy prices and fuel security have focussed the attention of process industries on their energy efficiency and opportunities for improvement. The main objective of this research study was to investigate technologies needed to exploit the large amount of low grade heat available from a flue gas condensing system through industrial condensing boilers. The technology and application of industrial condensing boilers in various heating systems were extensively reviewed. As the condensers require site-specific engineering design, a case study was carried out to investigate the feasibility (technically and economically) of applying condensing boilers in a large scale district heating system (40 MW). The study showed that by recovering the latent heat of water vapour in the flue gas through condensing boilers, the whole heating system could achieve significantly higher efficiency levels than conventional boilers. In addition to waste heat recovery, condensing boilers can also be optimised for emission abatement, especially for particle removal. Two technical barriers for the condensing boiler application are corrosion and return water temperatures. Highly corrosion-resistant material is required for condensing boiler manufacture. The thermal design of a 'case study' single pass shell-and-tube condensing heat exchanger/condenser showed that a considerable amount of thermal resistance was on the shell-side. Based on the case study calculations, approximately 4900 m 2 of total heat transfer area was required, if stainless steel was used as a construction material. If the heat transfer area was made of carbon steel, then polypropylene could be used as the corrosion-resistant coating material outside the tubes. The addition of polypropylene coating increased the tube wall thermal resistance, hence the required heat transfer area was approximately 5800 m 2 . Net Present Value (NPV) calculations showed that the choice of a carbon

    Corrosion is a major degradation mechanism of metals and alloys which significantly affects the global economy with an average loss of 3.5% of GDP of several countries in many important industrial sectors including chemical, petrochemical, power, oil, refinery, fertilizer etc. The demand for higher efficiency and achieving name plate capacity, in addition to ever increasing temperatures, pressures and complexities in equipment geometry of industrial processes, necessitate utmost care in adopting appropriate corrosion management strategies in selecting, designing, fabricating and utilising various materials and coatings for engineering applications in industries. Corrosion control and prevention is an important focus area as the savings achieved from practicing corrosion control and prevention would bring significant benefits to the industry. Towards this, advanced corrosion management strategies starting from design, manufacturing, operation, maintenance, in-service inspection and online monitoring are essential. At the Indira Gandhi Centre for Atomic Research (IGCAR) strategic corrosion management efforts have been pursued in order to provide solutions to practical problems emerging in the plants, in addition to innovative efforts to provide insight into mechanism and understanding of corrosion of various engineering materials and coatings. In this presentation the author highlights how the nuclear industry benefited from the practical approach to successful corrosion management, particularly with respect to fast breeder reactor programme involving both reactor and associated reprocessing plants.

    2009-01-01

    In the fuel cycle, converting UF 6 to UO 2 powder is an intermediate step for fabrication of pellets for fuel assemblies to be used in nuclear power plants. The basic proposal common to the different powder fabrication processes is to provide raw material capable of being processed into the form of pellets. The wet processes is the most often used industrially and are divided in two categories: the ADU (Ammonium Diuranate) and AUC (Ammonium Uranyl Carbonate) processes, whose names originate in the precipitate obtained in aqueous solution during the intermediate steps of UO 2 powder fabrication. It has known that the powder characteristics have a considerable influence in the UO 2 pellet manufacturing and quality characteristics. INB has used the AUC process to produce UO 2 pellets and supply fuel to Angra 1 and 2 Nuclear Power Plants. Despite of this process is characterized by the precipitation of a different intermediate precipitate compared to the ADU route (i.e., (NH 4 ) 4 UO 2 (CO 3 ) 3 , in the AUC process, and (NH 4 ) 2 U 2 O 7 in ADU process) leading to some slight differences in the final pellet microstructure, it has been considered that the models that predict the pellet behavior during irradiation in a nuclear reactor are basically the same compared to those used to predict the pellets form the ADU process. In order to evaluate how different the pellets originated from these two industrial routes are, this paper aims to compare the INB production historical data (Angra 1, Cycles 14 and 15) with the key parameters of a common product specification from the ADU process.

    The U.S. Department of Transportation (DOT) and the U.S. Nuclear Regulatory Commission (NRC) have prepared a comprehensive set of draft guidance for shippers and inspectors to use when applying the newly imposed regulatory requirements for low specific activity (LSA) material and surface contaminated objects (SCOs). These requirements represent significant departures in some areas from the manner in which these materials and objects were regulated by the earlier versions of the regulations. The proper interpretation and application of the regulatory criteria can require a fairly complex set of decisions be made. To assist those trying these regulatory requirements, a detailed set of logic-flow diagrams representing decisions related to multiple factors were prepared and included in the draft report for comment on Categorizing and Transporting Low Specific Activity Materials and Surface Contaminated Objects, (DOT/NRC, 1997). These logic-flow diagrams, as developed, are specific to the U.S. regulations, but were readily adaptable to the IAEA regulations. The diagrams have been modified accordingly and tied directly to specific paragraphs in IAEA Safety Series No. 6. This paper provides the logic-flow diagrams adapted in the IAEA regulations, and demonstrated how these diagrams can be used to assist consignors and inspectors in assessing compliance of shipments with the LSA material and SCO regulatory requirements.

    The Nation's economic prosperity and military security depend heavily on development and commercialization of advanced materials. Materials are a key facet of many technologies, providing the key ingredient for entire industries and tens of millions of jobs. With foreign competition in many areas of technology growing, improvements in materials and associated processes are needed now more than ever, both to create the new products and jobs of the future and to ensure that U.S. industry and military forces can compete and win in the international arena. The Federal Government has invested in materials research and development (R&D) for nearly a century, helping to lay the foundation for many of the best commercial products and military components used today. But while the United States has led the world in the science and development of advanced materials, it often has lagged in commercializing them. This long-standing hurdle must be overcome now if the nation is to maintain its leadership in materials R&D and the many technologies that depend on it. The Administration therefore seeks to foster commercialization of state-of-the-art materials for both commercial and military use, as a means of promoting US industrial competitiveness as well as the procurement of advanced military and space systems and other products at affordable costs. The Federal R&D effort in Fiscal Year 1994 for materials science and technology is an estimated $2123.7 million. It includes the ongoing R&D base that support the missions of nine Federal departments and agencies, increased strategic investment to overcome obstacles to commercialization of advanced materials technologies, interagency cooperation in R&D areas of mutual benefit to leverage assets and eliminate duplicative work, cost-shared research with industrial and academic partners in critical precompetitive technology areas, and international cooperation on selected R&D topics with assured benefits for the United States.

    Full Text Available PL (product liability response system is an enterprise-wide system that prevents company’s financial loss due to PL-related accidents. Existing researches on PL response system are mainly focused on preventive and/or defense strategies for the companies. Also, it is obvious that each industry has their original characteristics related on PL issues. It means industry-specific characteristics should be considered to adopt PL response strategies. Thus, this paper aims to discuss industry-specific PL response system and their components. Based on prior researches, we tried to reveal the possibility of its application to manufacturing companies of existing PL response strategies using Delphi method with PL experts. Based on first round results, we tried to classify existing PL strategies of manufacturing companies into several categories. To validate our suggestion for essential components of PL response system, second round Delphi method are applied. Analytic hierarchy process (AHP technique will be applied to identify a prioritized list of each components and strategies. Existing PL response strategies could be categorized with six components – strategy, technology, investment, training, awareness, and organization. Among six components, Technology – it represents the technology needed for improving the safety of all products – is the most important components to prepare PL accidents. The limitation of this paper is on the size of survey and variety of examples. However, the future study will enhance the potential of the proposed method. Regardless of rich research efforts to identify PL response strategies, there is no effort to categorize these strategies and prioritized them. Well-coordinated and actionable PL response strategies and their priorities could help small-and-medium sized enterprise (SME to develop their own PL response system with their limited resources.

    The heavy ceramic industry (building materials and refractory products manufacture) is an important source of pollutants to the environment. For this reason these industrial sub-sectors are included in prevention and control pollution policies, specifically those of the European Union. The IPPC Directive pays particular attention to the mineral industries, not least to the ceramic industry (epigraph 3.5, Annex I). In this paper, a methodology which is being applied to support IPPC installations and the competent administrative authority in Galicia (NW Spain) is presented. For that, the Galician heavy ceramic industry is analysed, as also are the ways to study the Best Available Techniques (BAT) with a view to establishing the emission limit values (ELV) for each specific case. Hence, a technological state of the art has been carried out for both sub-sectors, from the point of view of implementation of the IPPC in Galicia. Following this, the processes are described briefly and an analysis of the consumption and emission levels of the main pollutants is made. An inventory that includes the best environmental practices and the preventive and abatement candidate techniques as BAT was elaborated for both considered sub-sectors. An information data sheet for each candidate BAT is presented as a method to help both the industries and the competent authority to identify a candidate technique of the inventory as BAT. Three illustrative examples of the application of this procedure are presented for different emissions to environmental media for Galician installations.

    The mission of the U.S. Department of Energy/National Nuclear Security Administration's (NNSA) Office of Radiological Security (ORS) is to protect high-activity radiological materials around the globe. ORS works domestically within the United States and collaborates with over 80 countries to protect medical, industrial, research and other radiological sources from being used by malicious actors in a radiological dispersal device (RDD) or radiation exposure device (RED). One area of specific concern is mobile radioactive sources, such as those used in radiography to inspect welds or metal integrity, and those in the oil and gas industry to characterize exploration and production wells in pursuit of oil caches. These mobile radiological sources are of sufficient Curie quantities to be categorized as desirable sources for malicious actors. This presentation will provide an overview of a mobile source tracking system developed by ORS in conjunction with Pacific Northwest National Laboratory (PNNL), and will discuss how the system can contribute to source security, as well as next steps to pilot this technology

    Full Text Available The competition of maintenance services in the offshore wind industry is continually increasing. The quality of the services acts as the distinguishing feature in the industry. Furthermore, there are public standards, which lead to the permanent necessity to offer further education and training programs for employees. To meet the requirements for further training in the specific field of application within the offshore wind industry, a gamified e-learning application has been developed and is introduced in this paper. It consists of a complete solution, which contains the automated analysis of service protocols to identify qualification needs, the involvement of service technicians in the generation of learning materials, the preparation, transmission as well as the further development of those materials in accordance with the principles of e-learning. Finally, the solution contains a gamified mobile application for qualification, which is designed to meet the individual learning needs of the service technicians. This concept paper follows a problem-centred approach. Based on the current state of technology and research, the problem and motivation are identified and the urgency is verified. Furthermore, a detailed specification of the solution and a first implementation approach is presented.

  1. The Use of Tunnel Muck as Industrial Raw Material: Two Case-Studies

    Marini, P.; Bellopede, R.

    2013-03-01

    The re-use of rock as an industrial material requires more treatments than those foreseen for the reuse of muck as an aggregate for concrete and for road construction. The treatments always start with comminution, which has the goal of liberating the rock-forming minerals. Liberation is achieved with the appearance of grains which are composed of only one mineral. The subsequent treatment steps are based on the physical-mechanical-chemical properties of the different minerals, that is, density, magnetic susceptibility, wettability etc. Magnetic separation and flotation, the two techniques examined in this research, are the two most common techniques used in industrial mineral production plants. The mucks that were analysed are from the Omegna and Brennero tunnels, both of which are granitic rocks with different textures. From the analysis and comparison of the preliminary treatment results, it has been possible to optimise the treatment method. Petrographic, mineralogic and firing tests have been conducted to evaluate the obtained results. High-gradient magnetic separation (HGMS) on defined grain sizes appears to be suitable to obtain a product with a high feldspar-quartz content which could be used in the ceramic field.

    In the past, industry radiation protection programs were built almost exclusively around radiation safety and the minimization of radiation dose exposure to employees. Over the last decade, and especially the last few years, the emphasis has shifted to include the physical security and enhanced control of radioactive materials. The threat of nuclear and radiological terrorism is a genuine international security concern. In May 2004, the U.S. Department of Energy/U.S. National Nuclear Security Administration unveiled the Global Threat Reduction Initiative (GTRI) to respond to a growing international concern for the proper control and security of radioactive and nuclear materials. An integral part of the GTRI, the International Radiological Threat Reduction (IRTR) Program, was established in February 2002, originally as a Task Force. The IRTR Program is foremost a government-to-government cooperative program with the mission to reduce the risk posed by vulnerable radioactive materials that could be used in a Radioactive Dispersal Device (RDD). However, governments alone cannot prevent the misuse and illicit trafficking of radioactive sources. By expanding the role of private industry as a partner, existing government regulatory infrastructures can be enhanced by formulating and adopting industry self-regulation and self-policing measures. There is international concern regarding the security and control of the vast number of well-logging sources used during oil exploration operations. The prevalence of these sources, coupled with their portability, is a legitimate security concern. The energy exploration industry has well established safety and security protocols and the IRTR Program seeks to build on this foundation. However, the IRTR Program does not have sufficient resources to address the issue without industry assistance, so it is looking to the oil and gas industry to help identify alternative means for accomplishing our mutual objectives.

    By imaging the X-ray spectral properties or ‘colours’ we have shown how material specific imaging can be performed. Using a pixelated energy-dispersive X-ray detector we record the absorbed and emitted hard X-radiation and measure the energy (colour) and intensity of the photons. Using this technology, we are not only able to obtain attenuation contrast but also to image chemical (elemental) variations inside objects, potentially opening up a very wide range of applications from materials science to medical diagnostics.

    Thorium (Th) as nuclear fuel is clean and safe and offers significant advantages over uranium. The technology for several types of thorium reactors is proven but still must be developed on a commercial scale. In the case of commercialization of thorium nuclear reactor thorium raw materials will be on demand. With this, mining and processing companies producing Th and rare earth elements will require prompt and reliable methods and instrumentation for Th quantitative on-line analysis. Potential applicability of X-ray fluorescence conveyor analyzer CON-X series is discussed for Th quantitative or semi-quantitative on-line measurement in several types of Th-bearing materials. Laboratory study of several minerals (zircon sands and limestone as unconventional Th resources; monazite concentrate as Th associated resources and uranium ore residues after extraction as a waste product) was performed and analyzer was tested for on-line quantitative measurements of Th contents along with other major and minor components. Th concentration range in zircon sand is 50-350 ppm; its detection limit at this level is estimated at 25- 50 ppm in 5 minute measurements depending on the type of material. On-site test of the CON-X analyzer for continuous analysis of thorium traces along with other elements in zircon sand showed that accuracy of Th measurements is within 20% relative. When Th content is higher than 1% as in the concentrate of monazite ore (5-8% ThO_2) accuracy of Th determination is within 1% relative. Although preliminary on-site test is recommended in order to address system feasibility at a large scale, provided results show that industrial conveyor XRF analyzer CON-X series can be effectively used for analytical control of mining and processing streams of Th-bearing materials.

    One of the main aspects of the nuclear fuel is the selection of materials for the components. The operating conditions of the fuel elements impose a major challenge to materials: high temperature, corrosive aqueous environment, high mechanical properties, long periods of time under these extreme conditions and what is the differentiating factor; the effect of irradiation. The materials are selected to fulfill these severe requirements and also to be able to control and to predict its behavior in the working conditions. Their development, in terms of composition and processing, is based on the continuous follow-up of the operation behavior. Many of these materials are specific of the nuclear industry, such as the uranium dioxide and the zirconium alloys. This article presents the selection and development of the nuclear fuel materials as a function of the services requirements. It also includes a view of the new nuclear fuels materials that are being raised after Fukushima accident. (Author)

    The correlation between the catalytic activity towards N 2 O decomposition and fuel type was studied for the bed materials sampled from the bottom bed of two industrial CFB boilers, a 12MW th and a 550MW th , burning biomass fuels and wastes, alone or as a mixture. It was found that the elemental composition of the surface of the bed material particles changed according to the composition of the ash from the parent fuel. The measured catalytic activity of the bed material samples increased with the amount of the catalytically active oxides (CaO, MgO, Fe 2 O 3 , Al 2 O 3 ). In the case of limestone addition, the activity of the bed material was influenced by both the elemental composition of the fuel, and the ratio between lime and sulfated lime

    In the context of CO{sub 2} neutral and regenerative energy production, the field of thermoelectrics has shifted more and more into the focus of scientific research in the last few years. Particularly a lot of research projects were started in the field of energy autarkic sensor technology and the so called energy harvesting, i.e. the recycling of otherwise lost energy. A potentially huge industrial branch for thermoelectric applications is the automotive industry with a main emphasis on generating electricity out of the waste heat of combustion engines with the help of thermoelectric generators or using Peltier cooling to replace conventional air conditioning in the passenger compartment. In addition, many niche applications are possible, e.g. as sensors for measuring the air pressure of tires etc. The applications of thermoelectric devices are very versatile. We analyse the potential of the state-of-the-art thermoelectric materials SiGe, PbTe, Bi{sub 2}Te{sub 3}, FeSi{sub 2} and potentially ZnO with respect to employment in four types of applications, classified by mobile vs stationary and specialized vs. mass application. The selection criteria comprise efficiency, materials availability, costs, environmental friendliness and toxicity. Based on these criteria, a decision matrix for choosing the appropriate material system for a specific application is defined. (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  13. Urban planning and industry in Spain: A novel methodology for calculating industrial carbon footprints

    Zubelzu, Sergio; Álvarez, Roberto

    2015-01-01

    In this paper we present a methodology for calculating the carbon footprint of the industrial sector during the urban planning stage in order to clearly develop and implement preventive measures. The methodology created focuses on industrial urban planning procedures and takes into account urban infrastructure in the characterization of GHG emissions. It allows for the implementation of preventive measures based on sustainability design criteria. The methodology was derived for specific industrial activity categories and was tested on a group of municipalities in a province south of Madrid, Spain. The results indicate that the average carbon footprint of industrial activities varies between 137.36 kgCO 2eq /m 2 e and 607.25 kgCO 2eq /m 2 e depending on the activity. Gas and electricity are the most important emissions sources for the most polluting industrial activities (chemical and nonmetal mineral products), while transportation is the most important source for every other activity. Municipalities can have a decisive influence on the industrial carbon footprint because, except for waste management and two industrial activities related to electricity, the majority of reductions can be achieved through urban planning decision variables. -- Highlights: •Model to calculate industrial carbon footprint in urban planning stage is proposed. •Specific industrial activities planned have a strong effect on carbon footprint. •Gas and electricity are the most relevant sources for the most pollutant industries. •Transport is relevant source for the less pollutant industries. •Municipalities can decisively influence on industrial carbon footprint

    1999-08-01

    This report describes a closed-chamber method for laboratory measurements of the rate at which radon-222 degasses (exhales) from small building material samples. The chamber is 55 L in volume and the main sample geometry is a slab of dimensions 5x30x30 cm 3 . Numerical modelling is used to assess (and partly remove) the bias of the method relative to an ideal measurement of the free exhalation rate. Experimental results obtained with the method are found to be in agreement with the results of an open-chamber method (which is subject to different sources of error). Results of radon-222 exhalation rate measurements for 10 samples of Danish building materials are reported. Samples include ordinary concrete, lightweight aggregate concrete, autoclaved aerated concrete, bricks, and gypsum board. The maximum mass-specific exhalation rate is about 20 mBq h -1 kg -1 . Under consideration of the specific applications of the investigated building materials, the contribution to the indoor radon-222 concentration in a single-family reference house is calculated. Numerical modelling is used to help extrapolate the laboratory measurements on small samples to full scale walls. Application of typical materials will increase the indoor concentration by less than 10 Bq m -3 . (au)

    Immobilization of low and intermediate level.radioactive liquid wastes in different matrices: ordinary Portland cement and cement mixed with some industrial byproduct: by-pass kiln cement dust, blast furnace slag and ceramic sludge was studied. The effect of these industrial by-product materials on the compressive strength, water immersion, radiation effect and teachability were investigated. The obtained results showed that, these industrial by-product improve the cement pastes where they increase the compressive strength, decrease the leaching rate for radioactive cesium-137 and cobalt-60 ions through the solidified waste forms and increase resistance for y-radiation. It is found that, solidified waste forms of intermediate level liquid waste (ILLW) had high compressive strength values more than those obtained from low level liquid waste (LLLW). The compressive strength increased after immersion in different leachant for one and three months for samples with LLLW higher than those obtained for ILLW. The cumulative fractions released of cesium-137 and cobalt-60 of solidified waste forms of LLLW was lower than those obtained for ILLW

    Abstract A polysulfide material was synthesized by the direct reaction of sulfur and d‐limonene, by‐products of the petroleum and citrus industries, respectively. The resulting material was processed into functional coatings or molded into solid devices for the removal of palladium and mercury salts from water and soil. The binding of mercury(II) to the sulfur‐limonene polysulfide resulted in a color change. These properties motivate application in next‐generation environmental remediation and mercury sensing.

    The success achieved with large-scale plants for mechanical-biological residual waste treatment has led to a change of course in waste pretreatment. In view of the low emissions via the water and gas routes from landfilled wastes and the low costs of waste treatment some authorising authorities have meanwhile issued special licences pursuant to clause no. 2.4 of the Technical Code on Household Waste, thus enabling mechanical-biological residual waste treatment plants to continue operations beyond the year 2005. Beside offering a means of treatment and disposal, cost-effective mechanical-biological pretreatment also provides an opportunity for going over to material-flow-specific residual waste treatment. These process stages permit recirculating valuable materials and using other materials for energy production. They can be retrofitted on a modular basis in existing plants. If these advantages of the present innovative pretreatment methods are not used, then mechanical-biological pretreatment can still serve as a preparatory stage for thermal treatment. To date there has been no practical experience with this innovative method of residual waste treatment. However, industrial-scale trials have shown that each individual treatment stage is capable of being carried out successfully.

    1979-01-01

    Research undertaken in France on the upgrading of colliery shale has made it possible to extend the range of markets available for these products and to promote their utilization either in the untreated state or after processing. In the more specific field of lightweight building materials, our research has culminated in the development of manufacturing processes for aggregates and expanded nodular sands. The 100 mat3/day factory stage in the case of aggregates and the pilot plant (capacity several hundred kg/h) stage in the case of sands has been reached. However, the overall picture of slack demand for lightweight aggregates on the French market is little incentive for the rapid industrial development of manufacture of these materials.

    The k 0 parametric neutron activation analysis has been applied since 1995 in the Radiochemical Sector/CDTN, Belo Horizonte, Brazil. Several certified reference materials were studied with the aim of analysing biological samples. This work is related to an IAEA co-ordinated research project whose goal is to make a survey of the exposures to metals related to occupational diseases. It has been conducted by CDTN and government departments of health. The hair samples as bioindicators were donated by galvanising factory workers in Belo Horizonte. This city and surrounding area are important industrial centres and that industry is responsible for the majority of patients who look for medical assistance because of metal contamination. The Al, Co, Cu, Cr, La, Mn, Sb and V concentrations determined in the workers' samples suggest endogenous contamination. (author)

  8. The cellulases and their application in degrading agro-industrial waste

    Directory of Open Access Journals (Sweden)

    Wolfgang H. Schwarz

    2002-01-01

    Full Text Available A huge amount of lignocellulosic biomass is available which can be used to produce storable energy and basic material for the chemical industry. Its use is especially beneficial for a country's economy if it is waste material, which can be obtained at almost no cost and which presents an environmental burden. However, the polysaccharides present in biomass are difficult to degrade due to their heterogeneity and crystalline structure. This article addresses the enzymatic hydrolysis of cellulose by its natural degraders, the anaerobic bacteria. The difficulties of cellulose digestion are explained and the strategies used by the hydrolytic enzymes and enzyme systems, allowing for efficient degradation. The multitude of enzymes is uniform in having an identical chemical specificity, but differs in each component's action mode. Only by combining this with binding modules can efficient hydrolysis be performed. The variation of modular structures within a single enzyme family is an example of enzymatic activity's evolutionary diversification. A model for hydrolytically degrading natural cellulose is presented, but much more research has to be done to explain and describe the process on the molecular level, and to optimize an industrial enzymatic cellulose hydrolysis process.

Investigations were conduct by nuclear techniques and by physical and agrotechnical ethods. The alternative methods have been used by Tashkent state agrarian university. High sensitive and reliable multielement instrumental neutron activation analysis (INAA) and X-ray radiometric techniques for determination of 27 elements in plant have been developed in the Institute of nuclear physics (INP)

  10. Use of risk assessment in the nuclear industry with specific reference to the Australian situation

    International Nuclear Information System (INIS)

    Cameron, R.F.; Willers, A.

    2001-01-01

    The use of risk assessment in the nuclear industry began in the 1970s as a complementary approach to the deterministic methods used to assess the safety of nuclear facilities. As experience with the theory and application of probabilistic methods has grown, so too has its application. In the last decade, the use of probabilistic safety assessment has become commonplace for all phases of the life of a plant, including siting, design, construction, operation and decommissioning. In the particular case of operation of plant, the use of a 'living' safety case or probabilistic safety assessment, building upon operational experience, is becoming more widespread, both as an operational tool and as a basis for communication with the regulator. In the case of deciding upon a site for a proposed reactor, use is also being made of probabilistic methods in defining the effect of design parameters. Going hand in hand with this increased use of risk based methods has been the development of assessment criteria against which to judge the results being obtained from the risk analyses. This paper reviews the use of risk assessment in the light of the need for acceptability criteria and shows how these tools are applied in the Australian nuclear industry, with specific reference to the probabilistic safety assessment (PSA) performed of HIFAR

    This study is one of several made by Italian universities on behalf of ENEL to razionalize the energy demand pattern of some industrial branches and identify, among the various solutions, those that might bring about primary energy saving through the use of electricity. Specifically, this study was undertaken to verify the applicability of certain diaphragm separation technologies such as ultrafiltration in Italy, and to assess their energy-efficiency in terms of primary energy. Research carried out on this subject and the industrial experience of the last years point to the possibility of using ultrafiltration in the manufacture of typical soft cheese in direct competition with conventional technologies. The expected benefits of greater yield and energy saving are of great national economic relevance, since Italy imports both the raw material (milk) and energy resources.

    Computerized Tomographic (CT) has been used for a number of applications in the field of medicine and industry. For the last couple of years, the technique has been applied for the material characterization and detection of defects and flaws inside the industrial components of nuclear, aerospace and missile industries. A CT scanner of first generation was developed at the institute. The scanner has been used to demonstrate couple of applications of CT in the field of non destructive testing of materials. The data acquired by placing the test objects at various angles and scanning the object through a source detector assembly has been processed on a Pentium computer for image reconstruction using a filtered back projection method. The technique has been developed which can be modified and improved to study various other applications in materials science and a modern computerized tomographic facility can be established.

    Light-weighting of passenger cars using high-strength steel or aluminum is a common emissions mitigation strategy. We provide a first estimate of the global impact of light-weighting by material substitution on GHG emissions from passenger cars and the steel and aluminum industries until 2050. We develop a dynamic stock model of the global car fleet and combine it with a dynamic MFA of the associated steel, aluminum, and energy supply industries. We propose four scenarios for substitution of conventional steel with high-strength steel and aluminum at different rates over the period 2010-2050. We show that light-weighting of passenger cars can become a "gigaton solution": Between 2010 and 2050, persistent light-weighting of passenger cars can, under optimal conditions, lead to cumulative GHG emissions savings of 9-18 gigatons CO2-eq compared to development business-as-usual. Annual savings can be up to 1 gigaton per year. After 2030, enhanced material recycling can lead to further reductions: closed-loop metal recycling in the automotive sector may reduce cumulative emissions by another 4-6 gigatons CO2-eq. The effectiveness of emissions mitigation by material substitution significantly depends on how the recycling system evolves. At present, policies focusing on tailpipe emissions and life cycle assessments of individual cars do not consider this important effect.

    A study on the radiological hazard in Portland cement due to the presence of naturally occurring radioactive materials is being carried out. The Portland cement manufactured in the Islamabad/Rawalpindi region of Pakistan, intermediate products (clinker) and the various raw materials which compose the product have been analysed for 226 Ra, 232 Th and 40 K using a gamma spectrometry system with a N-type high-purity germanium detector of 80 % relative efficiency. From the measured gamma ray spectra, specific activities were determined. The mean values of the total specific activity of 226 Ra, 232 Th and 40 K are 34.2±11.9, 29.1±3.6 and 295.1±66.9 Bq kg -1 , respectively in Portland cement, 28.4±8.7, 11.3±1.7 and 63.1±17.3 Bq kg -1 , respectively in lime stone, 8.2±1.9, 16.2±3.9 and 187.7±53.2 Bq kg -1 , respectively in gypsum, 34.7±13.1, 41.2±6.7 and 187.6±17.2 Bq kg -1 , respectively in clay, 41.1±11.8, 39.3±6.9 and 195.1±29.2 Bq kg -1 , respectively in laterite and 51.1±18.2, 23.2±1.2 and 258.4±15.3 Bq kg -1 , respectively in clinker. The radium equivalent activities (Ra eq ), external hazard index (H ex ), internal hazard index (H in ), absorbed dose rate in air (D) and annual effective dose rate (E eff ) were also determined. The measured activity concentrations for these radio nuclides and radiological indices were compared with the reported national and international data. All these measured values are comparable with the worldwide data reported in UNSCEAR publications. (authors)

  17. Characterization and transformation of an industrial by-product (coated paper sludge into a pozzolanic material

    Full Text Available The effective re-use of industrial by-products calls for an understanding of their chemical, mineralogical and physical characteristics. The by-product used in this study was coated paper industry sludge from a plant whose sole prime material is recycled paper. Due to its high organic and calcium carbonate content and the presence of several clayey materials such as talc and kaolinite, incineration conditions had a significant effect on the mineralogy of such sludge. The present study examined the impact of such conditions on the pozzolanic properties of coated paper sludge. Several temperature intervals ranging from 600 to 750 ºC were studied to determine the conditions yielding the most promising pozzolanic properties.La necesidad de dar un correcto uso a los subproductos industriales requiere del conocimiento de sus características, tanto desde un punto de vista químico como mineralógico y físico. El subproducto utilizado para esta investigación es un lodo de papel estucado procedente de la industria papelera, la cual usa como materias primas un 100% de material reciclado. Debido al alto contenido de materia orgánica y carbonato cálcico y a la presencia de diferentes materiales arcillosos, como el talco y la caolinita, las condiciones de calcinación presentan un papel principal en la mineralogía de este lodo. En el actual trabajo se considera el papel que juegan estas condiciones, tiempo y permanencia en horno, en las propiedades puzolánicas del lodo de papel estucado como material cementante. Por esta razón, se estudiaron diferentes intervalos de temperatura, entre 600 y 750 ºC y 2 horas de permanencia en horno con el objetivo de obtener las mejores propiedades puzolánicas.

    The Low-level Radioactive Waste Disposal Project Center of Japan Atomic Energy Agency will settle on near surface disposal facilities with and without engineered barriers for radioactive wastes from research, industrial and medical facilities. Both of them are so called 'concrete pit type' and 'trench type', respectively. The technical standard of constructing and operating a disposal facility based on 'Law for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors' have been regulated partly by referring to that of 'Waste Management and Public Cleansing Law'. This means that the concrete pit type and the trench type disposal facility resemble an isolated type for specified industrial wastes and a non leachate controlled type final disposal site for stable industrial wastes, respectively. On the other, We plan to design a disposal facility with a liner system corresponding to a leachate controlled type final disposal site on a crucial assumption that radioactive wastes other than stable industrial wastes to be disposed into the trench type disposal facility is generated. By current nuclear related regulations in Japan, There are no technical standard of constructing the disposal facility with the liner system referring to that of 'Waste Management and Public Cleansing Law'. We investigate the function of the liner system in order to design a proper liner system for the trench type disposal facility. In this report, We investigated liner materials currently in use by actual leachate controlled type final disposal sites in Japan. Thereby important items such as tensile strength, durability from a view point of selecting proper liner materials were studied. The items were classified into three categories according to importance. We ranked proper liner materials for the trench type disposal facility by evaluating the important items per material. As a result, high density polyethylene(HDPE) of high elasticity type polymetric sheet was selected

    Closing the light water reactor fuel cycle and the use of mixed oxide fuels will produce materials such as solidified high level waste, cladding hulls and plutonium from Pu recycle fuel that have not been transported extensively in the past. Changes in allowable gaseous emissions from fuel cycle facilities may require the collection and transportation of radioactive noble gases and tritium. Although all of these materials could be transported in existing radioactive material packaging, economic considerations will make it desirable to develop new packaging specifically designed for each material. Conceptual package designs for these materials are reviewed. Special Nuclear Material transportation safeguards are expected to have a significant impact on future fuel cycle transportation. This subject is reviewed briefly. Other factors that could affect fuel cycle transportation are also discussed. Development of new packaging for radioactive materials is not believed to require the development of new technologies. New package designs will be primarily an adaptation of existing technology to fit the changing needs of a growing nuclear power industry. 23 references

    The aim of this research is to conduct cleaner production options for improving the environmental performance during the production of batik industry, the case of UKM batik, Malang, East Java. Batik industry is one of small and medium textile industry which has contribution to economic growth in Malang. However, during production the batik, it generates wastewater that has potential to decrease the environmental performance. Wastewater from Celaket batik industry has BOD, COD, TSS, and pH level is far larger than the threshold of water quality standard as a result of use chemical substance during the dyes processing. In order to prevent generating wastewater, this study utilized cleaner production options, such as substitution of input material.Substitution of input material for dyes process was implemented by replacement chemical dyes (e.g.indigosol, nafthol, rapid) with natural dyes (e.g. Indigofero Tintoria). Modifying of technology/equipment was conducted by developing wastewater treatment equipment to reduce waste of batik production. The implementation of this strategy was carried out by changing input material from chemical dyes with natural dyes. The CP uptake could reduce significantly the environmental impact in term of reduction of COD, BOD, and TSS.

    In this work the initial characterization of granular solid industrial waste from diatomaceous earth was carried out using techniques of Scanning Electron Microscopy and X-ray Diffraction. In a second stage leaching of the material was undertaken to the US Patent Number 5, 376,000 and 5, 356,601 obtaining the samples M1-S ph 2, M1-L ph, M1-S ph 10 and M1-L ph 10. In the third stage a new characterization of the samples obtained with the techniques of Scanning Electron Microscopy, X-ray Diffraction and Atomic Absorption Spectrometry was performed, the latter in order to determine the efficiency percentage of the leaching process. In the fourth stage the specimens for performing mechanical, physical and chemical tests were manufactured, using molds as PVC pipes of 1 inch in diameter and 2 inches in length, with a composition of 50% of diatomaceous earth and 50% of cement produced in each. Finally, in the fifth stage mechanical testing (compression resistance), physical (moisture absorption rate) and chemical (composition and structure of the material) are performed. In the last stage, when conducting mechanical testing with the test specimens, the presence of bubbles enclosed in each obtaining erroneous results noted, so it was necessary to develop the specimens again, obtaining in this occasion concentrations of 20:80, 40:60, 60:40 and 80:20 of diatomaceous earth with the cement. These results were analyzed to determine if the used material is suitable for the production of building materials such as bricks or partitions, being demonstrated by the tests carried out if they are eligible.

    During the last decade, the 2MeV/20kW electron beam (EB) accelerator located at BARC-BRIT complex, Vashi has been successfully utilised for non-thermal applications to develop speciality products useful for the industry. Polymer materials are exposed to high energy electrons to induce crosslinking and degradation reactions in a number of industrial products without the use of external chemicals and additives. Various EB crosslinked products viz. PE O-rings, automotive components, automobile tyres, electrical insulations, etc have been found to be much superior in quality compared to those produced conventionally. A process has been developed to enhance colours in the polished diamonds and gem stones using EB irradiation at the facility which has attracted much attention in the Indian diamond industry as a value-addition process. Recycling of polymer waste processed under EB to produce microfine PTFE powder, to reuse in automobile industry etc. has shown good potential for the industrial use. The process feasibility both in terms of economics and technology have been amply demonstrated on a technological scale by installing special conveyors at our facility for irradiating various industrial products. Around 100 km cable insulations, 1.5 million PE O-rings and more than 40000 carats of polished diamonds have been processed in our facility over a period of time on commercial scale. Encouraged with the results, Indian private entrepreneurs have set up dedicated EB machines in some of the most significant industries producing wire and cables, electrical gadgets based on polymer composites, automobile tyres and diamonds. The products are unique in properties and are in some cases, became import substitutes. The industry is now fully geared up to adapt the technology by realising the advantages viz ease in adaptability, convenient, safe and environmental-friendly nature. Encouraged by the process demonstrations, while five EB accelerators were setup and are in operation
