  6. Asteroids prospective energy and material resources

    2013-01-01

    The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power.   Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be lifted at a great expense from the surface of the Earth.   Resources derived from Asteroid not only can be brought back to Earth but could also be used to sustain human exploration of space and permanent settlements in space.   This book investigates asteroids' prospective energy and material resources. It is a collection of topics related to asteroid exploration, and utilization. It presents past and future technologies and solutions t...

  7. Polymeric materials from renewable resources

[Macromolecular Materials and Lignocellulosic Fibers Group, Center for Research on Science and Technology of BioResources, Institute of Chemistry of São Carlos, University of São Paulo, CP 780, 13560-970 São Carlos, São Paulo (Brazil)

    2016-05-18

    The goals of our studies have been the use of renewable raw materials in the preparation of polymeric materials with diversified properties. In this context, lignosulfonate, which is produced in large scale around the world, but not widely used in the production of polymeric materials, was used to replace phenol and polyols in the preparation of phenolic- (Ligno-PH) and polyurethane-type (Ligno-PU) polymers, respectively. These polymers were used to prepare composites reinforced with sisal lignocellulosic fibers. The use of lignosulfonate in the formulation of both types of polymers was beneficial, because in general composites with improved properties, specially impact strength, were obtained. Composites were also prepared from the so called “biopolyethylene” (HDPE), curaua lignocellulosic fiber, and castor oil (CO). All composites HDBPE/CO/Fiber exhibited higher impact strength, when compared to those of the corresponding HDBPE/Fiber. These results, combined with others (eg SEM images of the fractured surfaces) indicated that, in addition to acting as a plasticizer, this oil may have acted as a compatibilizer of the hydrophilic fiber with the hydrophobic polymer. The set of results indicated that (i) mats with nano (diameter ≤ 100nm) and/or ultrafine (submicron scale) fibers were produced, (ii) hybrid fibers were produced (bio-based mats composites), (iii) cellulosic pulp (CP) and/or lignin (Lig) can be combined with PET matrices to control properties such as stiffness and hydrophilicity of the respective mats. Materials with diversified properties were prepared from high content of renewable raw materials, thus fulfilling the proposed targets.

  10. Developing procedures for the handling of highly radioactive materials

    Wagner, M.L.

    1994-01-01

    Handling procedures for highly radioactive materials must be analyzed for the reduction of radiation dose. In keeping with ALARA principles, time, distance, and shielding must be used to maximum benefit during the job. After an initial risk assessment is accomplished, job pre-planning meetings and cold open-quotes walk-throughsclose quotes are held in order to engineer the best workable procedure given allocated resources, and to reduce personnel exposure. This paper shows the relationship between each step in the job development, over a number of actual jobs, drawing out how subtle changes in practice can affect the individual and team radiation dose

  11. Moon Prospective Energy and Material Resources

    2012-01-01

    The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration.   In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources.

  16. Resource Efficient Metal and Material Recycling

    Reuter, Markus A.; van Schaik, Antoinette

    Metals enable sustainability through their use and their recyclability. However, various factors can affect the Resource Efficiency of Metal Processing and Recycling. Some typical factors that enable Resource Efficiency include and arranged under the drivers of sustainability: Environment (Maximize Resource Efficiency — Energy, Recyclates, Materials, Water, Sludges, Emissions, Land); Economic Feasibility (BAT & Recycling Systems Simulation / Digitalization, Product vis-à-vis Material Centric Recycling); and Social — Licence to Operate (Legislation, consumer, policy, theft, manual labour.). In order to realize this primary production has to be linked systemically with typical actors in the recycling chain such as Original Equipment Manufacturers (OEMs), Recyclers & Collection, Physical separation specialists as well as process metallurgical operations that produce high value metals, compounds and products that recycle back to products. This is best done with deep knowledge of multi-physics, technology, product & system design, process control, market, life cycle management, policy, to name a few. The combination of these will be discussed as Design for Sustainability (DfS) and Design for Recycling (DfR) applications.

  17. Long Term Resource Monitoring Program procedures: fish monitoring

    Ratcliff, Eric N.; Glittinger, Eric J.; O'Hara, T. Matt; Ickes, Brian S.

    2014-01-01

    This manual constitutes the second revision of the U.S. Army Corps of Engineers’ Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) Long Term Resource Monitoring Program (LTRMP) element Fish Procedures Manual. The original (1988) manual merged and expanded on ideas and recommendations related to Upper Mississippi River fish sampling presented in several early documents. The first revision to the manual was made in 1995 reflecting important protocol changes, such as the adoption of a stratified random sampling design. The 1995 procedures manual has been an important document through the years and has been cited in many reports and scientific manuscripts. The resulting data collected by the LTRMP fish component represent the largest dataset on fish within the Upper Mississippi River System (UMRS) with more than 44,000 collections of approximately 5.7 million fish. The goal of this revision of the procedures manual is to document changes in LTRMP fish sampling procedures since 1995. Refinements to sampling methods become necessary as monitoring programs mature. Possible refinements are identified through field experiences (e.g., sampling techniques and safety protocols), data analysis (e.g., planned and studied gear efficiencies and reallocations of effort), and technological advances (e.g., electronic data entry). Other changes may be required because of financial necessity (i.e., unplanned effort reductions). This version of the LTRMP fish monitoring manual describes the most current (2014) procedures of the LTRMP fish component.

  18. Procedure for permanently storing radioactive material

    Canevall, J.

    1987-01-01

    This patent describes a method of storing radioactive material in a hollow construction having an access opening. The construction is located below the surface of the ground within a rock chamber. The chamber has walls, a floor, and a ceiling. The construction is completely spaced from the walls, floor, and ceiling of the rock chamber to form an outer spacing, and the construction is made of material impervious to water. The construction comprises a capsule storage area and a capsule handling passageway adjacent thereto having a track and being connected to a lift-shaft running to the surface. The method includes the steps of: completely filling the outer spacing between the walls, ceiling, and floor of the rock chamber and the construction with material not impervious to water; placing capsules containing the radioactive waste in encapsulated form into the capsule storage area; filling the storage area around the loaded capsule with a sealing material to enclose the capsules; repeating the placing and filling steps until the storage area has been completely filled in with the capsules and sealing material; loading the passageway adjacent the storage area with a removable material different than the sealing material; closing the construction and sealing the lift-shaft at least at the construction level and at ground level; and providing means for collecting any water penetrating into the outer spacing

  19. A procedure for the hardening of materials

    Dearnaley, G.

    1984-01-01

    A method of hardening metals or ceramics which have fcc, bcc or hcp structures in which two species of differing atomic radii are introduced into the material to be hardened. One species is of a size such that it can diffuse through the lattice normally. The other is of a size such that it can diffuse readily only along dislocations. Ion bombardment is the preferred method of introducing the species with different atomic radii. The material to be hardened is subjected to heat and plastic deformation so as to cause a large number of dislocations with jogs. The species meet at the jogs where they interact and are trapped and set up strain fields which prevent further deformation of the material. (author)

    2017-11-01

    The authors describe a multiinstitutional collaborative project to address a gap in global health training by creating a free online platform to share a curriculum for performing procedures in resource-limited settings. This curriculum called PEARLS (Procedural Education for Adaptation to Resource-Limited Settings) consists of peer-reviewed instructional and demonstration videos describing modifications for performing common pediatric procedures in resource-limited settings. Adaptations range from the creation of a low-cost spacer for inhaled medications to a suction chamber for continued evacuation of a chest tube. By describing the collaborative process, we provide a model for educators in other fields to collate and disseminate procedural modifications adapted for their own specialty and location, ideally expanding this crowd-sourced curriculum to reach a wide audience of trainees and providers in global health.

  7. Procedure for the assessment of material control and accounting systems

    Parziale, A.A.; Sacks, I.J.

    1979-01-01

    For the United States Nuclear Regulatory Commission, a procedure was developed and tested for the evaluation of Material Control and Accounting (MC and A) Systems at nuclear fuel facilities. This procedure, called the Structured Assessment Approach, SAA, subjects the MC and A system at a facility to a series of increasingly sophisticated adversaries and strategies. A fully integrated version of the computer codes which assist the analyst in this assessment will become available in October 1979. The concepts of the SAA and the results of the assessment of a hypothetical but typical facility are presented

  8. Procedures for determining MATMOD-4V material constants

    Lowe, T.C.

    1993-11-01

    The MATMOD-4V constitutive relations were developed from the original MATMOD model to extend the range of nonelastic deformation behaviors represented to include transient phenomena such as strain softening. Improvements in MATMOD-4V increased the number of independent material constants and the difficulty in determining their values. Though the constitutive relations are conceptually simple, their form and procedures for obtaining their constants can be complex. This paper reviews in detail the experiments, numerical procedures, and assumptions that have been used to determine a complete set of MATMOD-4V constants for high purity aluminum.

    Three mixing procedures have been standardized for the IDCA proficiency test—solid-solid, solid-liquid, and liquid-liquid. Due to the variety of precursors used in formulating the materials for the test, these three mixing methods have been designed to address all combinations of materials. Hand mixing is recommended for quantities less than 10 grams and Jar Mill mixing is recommended for quantities over 10 grams. Consideration must also be given to the type of container used for the mixing due to the wide range of chemical reactivity of the precursors and mixtures. Eight web site sources from container and chemical manufacturers have been consulted. Compatible materials have been compiled as a resource for selecting containers made of materials stable to the mixtures. In addition, container materials used in practice by the participating laboratories are discussed. Consulting chemical compatibility tables is highly recommended for each operation by each individual engaged in testing the materials in this proficiency test.

  14. Decision-directed materials-accounting procedures: an overview

    Shipley, J.P.

    1981-01-01

    With materials balances taken at intervals, methods for treating materials balance data and their use by safeguards decision-making are relatively straightforward. The emphasis on accounting in which balances may be drawn on a daily or weekly basis, raises anew questions in these two areas: (1) what is the most effective means of extracting the maximum amount of information; and (2) how should safeguards decision-makers use the results, and what impact does the decision process have on the analysis techniques. These questions lead to considering combinations of materials balances, which exposes a whole new set of concerns. For example, we must select the most appropriate combinations, which implies some consideration of possible diversion scenarios, such as abrupt or protracted. Control of the overall false-alarm rate is an important requisite of the composite procedure. Significant work has been done on loss estimators, but their role in the materials accounting decision process has only begun to be examined. Current criteria may require periodic statements with respect to materials loss; the analysis procedures must be structured to provide such information. This paper presents an overview of the current technology. Questions still to be answered are pointed out

  15. Maintenance modeling and optimization integrating human and material resources

    Martorell, S.; Villamizar, M.; Carlos, S.; Sanchez, A.

    2010-01-01

    Maintenance planning is a subject of concern to many industrial sectors as plant safety and business depend on it. Traditionally, the maintenance planning is formulated in terms of a multi-objective optimization (MOP) problem where reliability, availability, maintainability and cost (RAM+C) act as decision criteria and maintenance strategies (i.e. maintenance tasks intervals) act as the only decision variables. However the appropriate development of each maintenance strategy depends not only on the maintenance intervals but also on the resources (human and material) available to implement such strategies. Thus, the effect of the necessary resources on RAM+C needs to be modeled and accounted for in formulating the MOP affecting the set of objectives and constraints. In this paper RAM+C models to explicitly address the effect of human resources and material resources (spare parts) on RAM+C criteria are proposed. This extended model allows accounting for explicitly how the above decision criteria depends on the basic model parameters representing the type of strategies, maintenance intervals, durations, human resources and material resources. Finally, an application case is performed to optimize the maintenance plan of a motor-driven pump equipment considering as decision variables maintenance and test intervals and human and material resources.

  18. Efficiency of material accountability verification procedures: A case study

    Avenhaus, R.

    1976-01-01

    In the model agreement INFCIRC/153 the international nuclear materials safeguards system has been established such that the material accountability principle is the main safeguards tool, with containment and surveillance as complementary measures. In addition, it has been agreed that the plant operator generates all data necessary for the material balance establishment and reports them to the safeguards authority and furthermore, that these data are verified by representatives of the safeguards authority with the help of independent measurements. In this paper, the problem of the determination of the efficiency of the combined system - data verification and material balance establishment - is analysed. Here, the difficulty arises that the two statistical procedures used are not independent because part of the operator's data are used in both cases. It is the purpose of this paper to work out the procedure for calculating the systems efficiency, i.e. the overall guaranteed probability of detection for the whole system for an assumed diversion and a given false alarm rate as a function of the safeguards effort spent over a given interval of time. Simplified formulae are derived which allow for a quick determination of the whole system efficiency: it is shown that the correlation between the two parts of the total system can be neglected. Therefore, the total systems efficiency can be represented as the product of the efficiencies of the two subsystems. The method developed is applied to a concrete case of a chemical reprocessing plant for irradiated fuels on the basis of data collected earlier. (author)

  7. Pavement maintenance procedures with and without milling materials

    Rafiqul A. Tarefder

    2016-01-01

    Full Text Available This study evaluates maintenance treatment followed by different Districts of New Mexico Department of Transportation (NMDOT. In addition, two case studies on the use of old pavement materials, called the “millings”, in maintenance projects are reported. Based on this study, it is observed that none of the Districts have a written procedure for maintenance work. Rather Districts rely on the experience of the maintenance crew for conducting maintenance projects. All Districts prefer to use chip seal for maintenance irrespective of distress conditions of the pavements. Patching and crack sealing are usually done before chip sealing to extend the life of the chip seals. Sand seal, scrub seal, and slurry seal projects are not done by District maintenance crews but by outside contractors. It is also observed that all Districts are interested in using millings in maintenance projects and most have already used millings in at least one maintenance project with some success and failure. Most of the Districts have used coarse fraction of millings in chip seal projects successfully. However, they failed to find a proper way to process the fine fractions of millings. Case Study I shows that fine millings can be used to construct thin overlay when mixed with emulsion in pug mill or hot drums. Case Study II concludes that fine millings can be used as fine/sand seal successfully following the same procedure and using the same equipment as chip seal.

  8. Technology assessment of solar-energy systems. Materials resource and hazardous materials impacts of solar deployment

    Schiffman, Y. M.; Tahami, J. E.

    1982-04-01

    The materials-resource and hazardous-materials impacts were determined by examining the type and quantity of materials used in the manufacture, construction, installation, operation and maintenance of solar systems. The materials requirements were compared with US materials supply and demand data to determine if potential problems exist in terms of future availability of domestic supply and increased dependence on foreign sources of supply. Hazardous materials were evaluated in terms of public and occupational health hazards and explosive and fire hazards. It is concluded that: although large amounts of materials would be required, the US had sufficient industrial capacity to produce those materials; (2) postulated growth in solar technology deployment during the period 1995-2000 could cause some production shortfalls in the steel and copper industry; the U.S. could increase its import reliance for certain materials such as silver, iron ore, and copper; however, shifts to other materials such as aluminum and polyvinylchloride could alleviate some of these problems.

  14. Defining the anesthesia gap for reproductive health procedures in resource-limited settings.

    Anderson, R Eleanor; Ahn, Roy; Nelson, Brett D; Chavez, Jean; de Redon, Emily; Burke, Thomas

    2014-12-01

    In resource-limited settings, severe shortages of anesthetists and anesthesiologists lead to surgical delays that increase maternal and neonatal mortality and morbidity. To more clearly understand the individual components of the anesthesia gap pertaining to reproductive health surgeries and procedures in resource-limited settings. Medline, the Cochrane Library, CINAHL, Embase, and POPLINE were systematically searched for reports published before December 31, 2013. Search terms were related to obstetric surgery, resource-limited settings, and anesthesia. Studies that addressed the use of anesthesia in reproductive procedures in resource-limited settings were included. Reviewers independently evaluated the full text of identified studies, extracted information related to study objectives and conclusions, and identified the anesthesia gap. Overall, 14 publications met the inclusion criteria. A significant lack of infrastructure, equipment and supplies, and trained personnel were identified as key factors responsible for a lack of anesthesia services. A shortage of trained anesthesia providers, equipment, supplies, medications, and infrastructure, along with limitations in transportation in resource-limited settings have produced a wide gap between available anesthesia services and the demand for them for reproductive health surgeries and procedures. Safe, affordable, and scalable solutions to address the anesthesia gap are urgently needed. Copyright © 2014 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

  15. Code of Conduct on Biosecurity for Biological Resource Centres: procedural implementation.

    Rohde, Christine; Smith, David; Martin, Dunja; Fritze, Dagmar; Stalpers, Joost

    2013-07-01

    A globally applicable code of conduct specifically dedicated to biosecurity has been developed together with guidance for its procedural implementation. This is to address the regulations governing potential dual-use of biological materials, associated information and technologies, and reduce the potential for their malicious use. Scientists researching and exchanging micro-organisms have a responsibility to prevent misuse of the inherently dangerous ones, that is, those possessing characters such as pathogenicity or toxin production. The code of conduct presented here is based on best practice principles for scientists and their institutions working with biological resources with a specific focus on micro-organisms. It aims to raise awareness of regulatory needs and to protect researchers, their facilities and stakeholders. It reflects global activities in this area in response to legislation such as that in the USA, the PATRIOT Act of 2001, Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001; the Anti-Terrorism Crime and Security Act 2001 and subsequent amendments in the UK; the EU Dual-Use Regulation; and the recommendations of the Organization for Economic Co-operation and Development (OECD), under their Biological Resource Centre (BRC) Initiative at the beginning of the millennium (OECD, 2001). Two project consortia with international partners came together with experts in the field to draw up a Code of Conduct on Biosecurity for BRCs to ensure that culture collections and microbiologists in general worked in a way that met the requirements of such legislation. A BRC is the modern day culture collection that adds value to its holdings and implements common best practice in the collection and supply of strains for research and development. This code of conduct specifically addresses the work of public service culture collections and describes the issues of importance and the controls or

  16. Marine dredged sediments as new materials resource for road construction.

    Siham, Kamali; Fabrice, Bernard; Edine, Abriak Nor; Patrick, Degrugilliers

    2008-01-01

    Large volumes of sediments are dredged each year in Europe in order to maintain harbour activities. With the new European Union directives, harbour managers are encouraged to find environmentally sound solutions for these materials. This paper investigates the potential uses of Dunkirk marine dredged sediment as a new material resource for road building. The mineralogical composition of sediments is evaluated using X-ray diffraction and microscopy analysis. Since sediments contain a high amount of water, a dewatering treatment has been used. Different suitable mixtures, checking specific geotechnical criteria as required in French standards, are identified. The mixtures are then optimized for an economical reuse. The mechanical tests conducted on these mixtures are compaction, bearing capacity, compression and tensile tests. The experimental results show the feasibility of the beneficial use of Dunkirk marine dredged sand and sediments as a new material for the construction of foundation and base layers for roads. Further research is now needed to prove the resistance of this new material to various environmental impacts (e.g., frost damage).

  17. Rice Hulls as a Renewable Complex Material Resource

    Irina Glushankova

    2018-05-01

    Full Text Available As a result of rice grain processing, a big amount of waste (up to 20% is produced. It is mainly rice hulls. The main components of rice hulls are cellulose, lignin and mineral ash. The mineral ash quantity in rice hulls varies from 15 up to 20%, by weight of the rice hulls. The mineral ash consists of amorphous silica (opal-type. Due to the high content of silica in rice hulls, the material burns with difficulty under natural conditions, and it is biodegradably destroyed only with difficulty, when composted. Utilization of rice hulls then becomes an ecological problem due to huge rice production and its continuous growth. At the same time, the annual quantity of silica content in rice hulls is comparable with the quantity of amorphous silica produced as a mineral resource. The issue of manufacturing cellular glass silica construction materials from rice hulls as a renewable resource is discussed in this paper. The utilization technology is based on an amorphous silicon oxide with the use of energy from the combustion of the organic component of rice hulls.

    Vertakova, Y. V.; Babich, T. N.; Polozhentseva, Y. S.; Zvyagintsev, G. L.

    2017-10-01

    The article presents data on the influence of factors in the field of innovative technology of thermocatalytic depolymerization of solid household wastes (SHW) on the efficiency and prospects for the development of technogenic hydrocarbon raw materials resource reproduction. Process thermodynamics, reactions kinetics, the mechanism of thermolysis of secondary polymers in organic solvents have been studied by means of laboratory experiments. It is shown that different morphological groups of wastes dissolve practically at the same rate at temperatures of 250-310°C. A homogeneous product is formed in the liquid phase; the spread of values for the elements lies in the interval of 1.5-4.5 %; technological requirements of the stages of formation of boiler fuels are satisfied. Using the principles of patent analysis, new techniques of processing household waste components are proposed. The basics of energy-efficient and energy-saving processes of technogenic hydrocarbon raw materials resource reproduction have been laid. The possibility of increasing the production payback and intensification is shown. Ecological and demographic safety for population and technical and economic benefits from SHW processing are achieved.

  19. Assessment of material and technical resources of crop production technologies

    V. M. Beylis

    2017-01-01

    Full Text Available The author explains the general principles of influence of the material and technical resources (MTR on performance and efficiency of the main technological operations in crop production. Various technologies from the point of view of MTR expenses were estimated. The general tendencies in development of crop production technologies were revealed. The distribution of costs of materials and equipment to perform a variety of agricultural activities was determined. Cost indicators should be a guide in the search of innovative technological processes and working elements of agricultural machins. The greatest values of expenses of work, fuel, metal, and also, money where found. The concepts allowing to provide costs production reduction were formulated. To achieve the maximum productivity with the minimum expenses, the perspective calculations shoul be based on «progressive» agrotechnologies. When determining progressive agrotechnology it is necessary on reasonable grounds to approach indicators of crop productivity in various agrozones and regions of the country. For an assessment of efficiency of MTR by crop production and ensuring decrease in resource intensity of agricultural products by search and use of essentially new technologies for energy saving when performing agricultural operations, an integrated percentage indicator of comparison of progressive technologies with the applied ones was developed. MTR at application of new progressive crop production technologies by integrated percentage index were estimated. This indicator can be used for definition of efficiency of MTR. Application of the offered technique will promote an effective assessment of MTR, decrease in resource intensity by search and developments of essentially new technologies of performance of operations in crop production.

  20. Comparison of Two Xenograft Materials Used in Sinus Lift Procedures: Material Characterization and In Vivo Behavior

    María Piedad Ramírez Fernández

    2017-06-01

    Full Text Available Detailed information about graft material characteristic is crucial to evaluate their clinical outcomes. The present study evaluates the physico-chemical characteristics of two xenografts manufactured on an industrial scale deproteinized at different temperatures (non-sintered and sintered in accordance with a protocol previously used in sinus lift procedures. It compares how the physico-chemical properties influence the material’s performance in vivo by a histomorphometric study in retrieved bone biopsies following maxillary sinus augmentation in 10 clinical cases. An X-ray diffraction analysis revealed the typical structure of hydroxyapatite (HA for both materials. Both xenografts were porous and exhibited intraparticle pores. Strong differences were observed in terms of porosity, crystallinity, and calcium/phosphate. Histomorphometric measurements on the bone biopsies showed statistically significant differences. The physic-chemical assessment of both xenografts, made in accordance with the protocol developed on an industrial scale, confirmed that these products present excellent biocompatibilitity, with similar characteristics to natural bone. The sintered HA xenografts exhibited greater osteoconductivity, but were not completely resorbable (30.80 ± 0.88% residual material. The non-sintered HA xenografts induced about 25.92 ± 1.61% of new bone and a high level of degradation after six months of implantation. Differences in the physico-chemical characteristics found between the two HA xenografts determined a different behavior for this material.

  1. Mathematical actions as procedural resources: An example from the separation of variables

    Michael C. Wittmann

    2015-09-01

    Full Text Available [This paper is part of the Focused Collection on Upper Division Physics Courses.] Students learning to separate variables in order to solve a differential equation have multiple ways of correctly doing so. The procedures involved in separation include division or multiplication after properly grouping terms in an equation, moving terms (again, at times grouped from one location on the page to another, or simply carrying out separation as a single act without showing any steps. We describe student use of these procedures in terms of Hammer’s resources, showing that each of the previously listed procedures is its own “piece” of a larger problem solving activity. Our data come from group examinations of students separating variables while solving an air resistance problem in an intermediate mechanics class. Through detailed analysis of four groups of students, we motivate that the mathematical procedures are resources and show the issues that students must resolve in order to successfully separate variables. We use this analysis to suggest ways in which new resources (such as separation come to be.

  6. Facilitating or Restraining Access To Genetic Resources? Procedural Dimensions In Kenya

    Evanson Chege Kamau

    2009-09-01

    Full Text Available States have the right to regulate access to biological resources subject to national legislations. Allowing, restricting or prohibiting access, however, requires a balance to avoid contravention of the objectives of the Convention on Biological Diversity. The Convention requires that, in regulating access, the measures adopted do not become a hindrance to access. In many instances, however, this has been the case. Overreaction to previous cases of bio-piracy and over-enthusiasm to tap into the benefits from discovered genetic resources have caused many provider countries to either over-regulate or extremely complicate access procedures, thus deterring access. In some instances, over-regulation and complex procedures are to be blamed on the users’ reluctance to collaborate with providers in minimising or eliminating abuse. Also, the need to protect certain rights over genetic resources or of an intellectual (property character, for example, might at times complicate regulation. While it is appreciated that such issues must also be taken into account in addressing and creating a balance in access and benefit sharing, a discussion embracing all these aspects cannot be captured within the ambit of this article. Focus is therefore laid on the procedural dimensions of access in Kenya and suggestions for improvement.

  8. Procedure for the assessment of material control and accounting systems

    Maimoni, A.; Sacks, I.; Cleland, L.

    1978-01-01

    The current status of the LLL program for MC and A system assessment is reviewed. Particular emphasis is given to the assessment procedure and results. The integrated approach we have taken includes many of the functions normally assigned to physical security. Deceit and tampering are explicitly considered. The results of such a detailed assessment include a systematic identification of adversary targets; the most vulnerable portions of the safeguards system; the number and type of adversaries required, in collusion, to fail the system; and the conditional probabilities of safeguard system failure for a variety of assumptions. The assessment procedure was demonstrated by analyzing a prototype fuel cycle facility, the Test Bed. We believe our methodology will be useful to the NRC as a means of performing detailed, objective assessments. The nuclear industry also should find it valuable as a design tool

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

    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.

  14. [Essential procedure and key methods for survey of traditional knowledge related to Chinese materia medica resources].

    Cheng, Gong; Huang, Lu-qi; Xue, Da-yuan; Zhang, Xiao-bo

    2014-12-01

    The survey of traditional knowledge related to Chinese materia medica resources is the important component and one of the innovative aspects of the fourth national survey of the Chinese materia medica resources. China has rich traditional knowledge of traditional Chinese medicine (TCM) and the comprehensive investigation of TCM traditional knowledge aims to promote conservation and sustainable use of Chinese materia medica resources. Building upon the field work of pilot investigations, this paper introduces the essential procedures and key methods for conducting the survey of traditional knowledge related to Chinese materia medica resources. The essential procedures are as follows. First is the preparation phrase. It is important to review all relevant literature and provide training to the survey teams so that they have clear understanding of the concept of traditional knowledge and master key survey methods. Second is the field investigation phrase. When conducting field investigations, survey teams should identify the traditional knowledge holders by using the 'snowball method', record the traditional knowledge after obtaining prior informed concerned from the traditional knowledge holders. Researchers should fill out the survey forms provided by the Technical Specification of the Fourth National Survey of Chinese Materia Medica Resources. Researchers should pay particular attention to the scope of traditional knowledge and the method of inheriting the knowledge, which are the key information for traditional knowledge holders and potential users to reach mutual agreed terms to achieve benefit sharing. Third is the data compilation and analysis phrase. Researchers should try to compile and edit the TCM traditional knowledge in accordance with intellectual property rights requirements so that the information collected through the national survey can serve as the basic data for the TCM traditional knowledge database. The key methods of the survey include regional

    2017-03-01

    Full Text Available Value of intellectual resources in modern economy due to which the assets of human resources became one of the factors of formation of value of systems on the basis of their investing, is considered. Adequate evaluation of employees’ activities as one of the basic resources will make it possible to meet competition under conditions of "survival" through periodic formation of socio-economic profile and stimulation of investment in human resources on the basis of the following technologies: formation of a balanced scorecard system, creation of a mechanism of formation and distribution of labour compensation funds, use of the golden section principle. Establishment of wages according to the golden section principle contributes to the stability and commitment of employees and increase of efficiency of investments in human resources, provided that it doubles the sales volume and should accordingly increase the wages of each employee by a factor of 1.62. Statistical analysis demonstrated that organizations that work using the golden section principle increased the labour productivity on average by 10-20 %, augmented the turnover by a factor of 1.3–1.5, minimized the costs by 15-20 %. Application of the golden section technology creates conditions necessary for economic growth on the basis of efficiency of investments in human resources.

    2016-01-01

    Simplified material models are commonly used in computational simulation of biological soft tissue as an approximation of the complicated material response and to minimize computational resources. However, the simulation of complex loadings, such as long-duration tissue swelling, necessitates complex models that are not easy to formulate. This paper strives to offer the updated Lagrangian formulation comprehensive procedure of various non-linear material models for the application of finite element analysis of biological soft tissues including a definition of the Cauchy stress and the spatial tangential stiffness. The relationships between water content, osmotic pressure, ionic concentration and the pore pressure stress of the tissue are discussed with the merits of these models and their applications.

  12. Evaluation of various digestion procedures for trace element contents of some food materials

    Demirel, Sule; Tuzen, Mustafa; Saracoglu, Sibel; Soylak, Mustafa

    2008-01-01

    The levels of trace elements in different types of food material consumed in Turkey were determined by flame and graphite furnace atomic absorption spectrometry. Food samples were digested with dry ashing, wet ashing and microwave digestion procedures in this study. The microwave digestion procedure was chosen for the digestion of all the food samples because it required shorter time and made higher recovery (specially for Se). Fe, Cu, Mn, Zn, Al and Se were determined by flame and graphite furnace atomic absorption spectrometry, respectively. Relative standard deviations (RSD) were found below 10%. The accuracy of the procedure was confirmed by certified reference materials. Moreover, this procedure was easier to use when compared with dry and wet digestions

  14. New Procedure for Compacting Prismatic Specimens of Cement-Treated Base Materials

    Alaitz Linares-Unamunzaga

    2018-06-01

    Full Text Available Understanding the long-term behaviour of cement-treated base materials is a key factor to improve its design and obtain environmentally friendly pavement base materials. Their characterization requires manufacturing prismatic specimens. However, various authors highlight the absence of standardized test methods for fabricating beams in the field and laboratory, which is not an easy task because it depends on the qualification and experience of the testing team. The aim of this paper is to present a new device and procedure for compacting prismatic specimens of cement-treated base materials. In this research, it was used for compacting soil-cement to simulate its performance as a road base material. This device employs elements that are generally available in a concrete laboratory test, such as a vibrating table or prismatic moulds. Once the procedure was established, and in order to verify its suitability, flexural and compressive strength tests were carried out. Results showed that the values obtained were consistent with this material and, despite the heterogeneity of the material, specimens from the same batch provided similar results and, hence, validated the compaction process. This new compacting procedure can improve understanding of the long-term performance of cement-treated materials from flexural and fatigue tests.

  16. [Management of human resources, materials, and organization processes in radioprotection].

    Coppola, V

    1999-06-01

    The radiologist must learn to face daily management responsibilities and therefore he/she needs the relevant knowledge. Aside from the mechanisms of management accounting, which differ only slightly from similar analysis methods used in other centers, the managing radiologist (the person in charge) is directly responsible for planning, organizing, coordinating and controlling radiation protection, a major discipline characterizing diagnostic imaging. We will provide some practical management hints, keeping in mind that radiation protection must not be considered a simple (or annoying) technical task, but rather an extraordinary positive element for the radiologist's cultural differentiation and professional identity. The managing radiologist can use the theory and practice of management techniques successfully applied in business, customizing them to the ethics and economics of health care. Meeting the users' needs must obviously prevail on balancing the budget from both a logical and an accounting viewpoints, since non-profit organizations are involved. In radiological practice, distinguishing the management of human from structural resources (direct funding is not presently available) permits to use internal benchmarking for the former and controlled acquisition and planned replacement of technologies in the latter, obviously after evaluation of specific indicators and according to the relevant laws and technical guidelines. Managing human resources means safeguarding the patient, the operator and the population, which can be achieved or improved using benchmarking in a diagnostic imaging department. The references for best practice will be set per tabulas based on the relevant laws and (inter)national guidelines. The physical-technical and bureaucratic-administrative factors involved will be considered as process indices to evaluate the gap from normal standards. Among the different elements involved in managing structural resources, the appropriate acquisition

  20. Resource planning of solid waste materials through process modelling as contribution to sustainable resource management; Ressourcenplanung fester Abfallstoffe mit Hilfe der Prozessmodellierung als Beitrag zum nachhaltigen Ressourcenmanagement

    Pehlken, Alexandra [Bremen Univ. (Germany). BIK, Institut fuer integrierte Produktentwicklung

    2010-10-15

    Raw materials are essential to satisfy our needs in energy and products. Many raw materials are restricted and far away from being endless available; therefore there is a strong intention of developing raw material- and energy-efficient production processes. Recycling processes provide a substantial contribution to sustainable resource management due to the supply of valuable secondary raw materials for new applications. Processing solid waste materials generate new secondary resources from residues as resources for new products. This saves primary resources and keeps up a long material life cycle. But material characterisation is an important issue to look at. Material properties ascertain the following application possibilities. It has to be noted that no processing technique can guarantee solely material flows with properties to substitute primary raw materials. There are always material flows that are of minor quality. This makes it difficult to assess the future potential of secondary raw materials to be available for following applications with specific quality demands. (orig.)

    Choi, Cheol Kyu; KIm, Yong Geon; Ji, Seung Woo; Kim, Kwang Pyo; Koo, Bon Cheol; Chang, Byung Uck

    2016-01-01

    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

    A. Nadal

    2017-06-01

    Full Text Available 3D printing for construction is stagnated at an early stage of development, especially regarding material optimization and procedural issues. These limitations are due to the specific knowledge that these technologies imply, the total cost of the machinery involved, and the lack of clear procedural guidelines. This paper presents a methodology that aims at overcoming these limitations through a workflow that allows for the ease of use of 6-axis robotic arms. A technique for the optimization of material usage is presented. A test case that shows the integration the design-to-fabrication process combining Integrated Robotic Systems (IRS and Additive Layer Manufacturing (ALM techniques is discussed. A structure-based approach to material optimization and smart infill patterning is introduced. A 0.4 x 0.4 x 1.5 m test part is shown as technological demonstrator.

  7. Procedure and apparatus for the determination of the gold content in a material containing gold

    1980-01-01

    This patent describes a method and apparatus for determining the gold content of materials, and in particular, of rock and stone samples. The procedure is based upon the irradiation of the material with neutrons and the determination of the intensity of the gamma radiation (279 keV) produced in the reaction 197 Au(n,n')sup(197m)Au. The neutron source used produces the neutrons by the deuteron-deuteron or deuteron-beryllium reaction. The energy of these neutrons is not high enough for producing fast neutron reactions in the other elements of the material. The apparatus described separates the samples with a gold content above a certain value by means of the procedure described above. (Th.P.)

  10. An Efficient Procedure for Removal and Inactivation of Alpha-Synuclein Assemblies from Laboratory Materials.

    Bousset, Luc; Brundin, Patrik; Böckmann, Anja; Meier, Beat; Melki, Ronald

    2016-01-01

    Preformed α-synuclein fibrils seed the aggregation of soluble α-synuclein in cultured cells and in vivo. This, and other findings, has kindled the idea that α-synuclein fibrils possess prion-like properties. As α-synuclein fibrils should not be considered as innocuous, there is a need for decontamination and inactivation procedures for laboratory benches and non-disposable laboratory material. We assessed the effectiveness of different procedures designed to disassemble α-synuclein fibrils and reduce their infectivity. We examined different commercially available detergents to remove α-synuclein assemblies adsorbed on materials that are not disposable and that are most found in laboratories (e.g. plastic, glass, aluminum or stainless steel surfaces). We show that methods designed to decrease PrP prion infectivity neither effectively remove α-synuclein assemblies adsorbed to different materials commonly used in the laboratory nor disassemble the fibrillar form of the protein with efficiency. In contrast, both commercial detergents and SDS detached α-synuclein assemblies from contaminated surfaces and disassembled the fibrils. We describe three cleaning procedures that effectively remove and disassemble α-synuclein seeds. The methods rely on the use of detergents that are compatible with most non-disposable tools in a laboratory. The procedures are easy to implement and significantly decrease any potential risks associated to handling α-synuclein assemblies.

  11. Conditional Monthly Weather Resampling Procedure for Operational Seasonal Water Resources Forecasting

    Beckers, J.; Weerts, A.; Tijdeman, E.; Welles, E.; McManamon, A.

    2013-12-01

    To provide reliable and accurate seasonal streamflow forecasts for water resources management several operational hydrologic agencies and hydropower companies around the world use the Extended Streamflow Prediction (ESP) procedure. The ESP in its original implementation does not accommodate for any additional information that the forecaster may have about expected deviations from climatology in the near future. Several attempts have been conducted to improve the skill of the ESP forecast, especially for areas which are affected by teleconnetions (e,g. ENSO, PDO) via selection (Hamlet and Lettenmaier, 1999) or weighting schemes (Werner et al., 2004; Wood and Lettenmaier, 2006; Najafi et al., 2012). A disadvantage of such schemes is that they lead to a reduction of the signal to noise ratio of the probabilistic forecast. To overcome this, we propose a resampling method conditional on climate indices to generate meteorological time series to be used in the ESP. The method can be used to generate a large number of meteorological ensemble members in order to improve the statistical properties of the ensemble. The effectiveness of the method was demonstrated in a real-time operational hydrologic seasonal forecasts system for the Columbia River basin operated by the Bonneville Power Administration. The forecast skill of the k-nn resampler was tested against the original ESP for three basins at the long-range seasonal time scale. The BSS and CRPSS were used to compare the results to those of the original ESP method. Positive forecast skill scores were found for the resampler method conditioned on different indices for the prediction of spring peak flows in the Dworshak and Hungry Horse basin. For the Libby Dam basin however, no improvement of skill was found. The proposed resampling method is a promising practical approach that can add skill to ESP forecasts at the seasonal time scale. Further improvement is possible by fine tuning the method and selecting the most

  12. Technical procedures for water resources: Volume 3, Environmental Field Program, Deaf Smith County Site, Texas: Final draft

    1987-08-01

    To ensure that the environmental field program comprehensively addresses the issues and requirements of the project, a site study plan (SSP) has been prepared for Water Resources (ONWI, 1987). This technical procedure (TP) has been developed to implement the field program described in the Water Resources Site Study Plan. This procedure provides the general method for the field collection of water and sediment samples from playa lakes using an Alpha horizontal type sampler or equivalent or a peristaltic pump for water and a KB-coring devise or ponar grab for sediments. The samples will be preserved and then shipped to a laboratory for analysis.

    Here, we introduce a novel concept for the fabrication of colored materials with significantly reduced dye leaching through covalent immobilization of the desired dye using plasma-generated surface radicals. This plasma dye coating (PDC) procedure immobilizes a pre-adsorbed layer of a dye functionalized with a radical sensitive group on the surface through radical addition caused by a short plasma treatment. The non-specific nature of the plasma-generated surface radicals allows for a wide variety of dyes including azobenzenes and sulfonphthaleins, functionalized with radical sensitive groups to avoid significant dye degradation, to be combined with various materials including PP, PE, PA6, cellulose, and PTFE. The wide applicability, low consumption of dye, relatively short procedure time, and the possibility of continuous PDC using an atmospheric plasma reactor make this procedure economically interesting for various applications ranging from simple coloring of a material to the fabrication of chromic sensor fabrics as demonstrated by preparing a range of halochromic materials.

  15. Program-oriented approach to resource saving issues in construction materials industry

    Novikova Galina

    2017-01-01

    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.

  17. Reuse and recovery of raw materials: Towards the achievement of a resource-efficient society

    Brunori, Claudia; Cutaia, Laura; Norabito, Roberto

    2015-01-01

    Resource efficiency plays a key role in the transition from a linear to a circular economy system. During the last few decades a rapid growth in the number of materials used across complex products has occurred. Given the high economic importance of critical raw materials combined with relatively high supply risk, securing reliable and undistorted access of certain raw materials is of growing concern across the globe. Development of eco-innovative approaches devoted to closing the loop of resources is strongly needed, allowing the connection between production cycles and their territory.

    Takahashi, Hideaki

    1992-01-01

    The quantitative nondestructive evaluation procedure for detecting in-service materials degradation of low alloy structural steels by both small punch test and the electrochemical method has been developed. The static and dynamic small punch test method have been developed in order to apply this technique to R and D study for fusion reactor material development, such as 14 MeV irradiation damage evaluation. The characteristic changes in polarization curves attributed to IGC have an excellent correlation with shifts in FATT caused by temper embrittlement for Cr-Mo and Cr-Mo-V steels. (author)

  1. Educational Material for 3D Visualization of Spine Procedures: Methods for Creation and Dissemination.

    Cramer, Justin; Quigley, Edward; Hutchins, Troy; Shah, Lubdha

    2017-06-01

    Spine anatomy can be difficult to master and is essential for performing spine procedures. We sought to utilize the rapidly expanding field of 3D technology to create freely available, interactive educational materials for spine procedures. Our secondary goal was to convey lessons learned about 3D modeling and printing. This project involved two parallel processes: the creation of 3D-printed physical models and interactive digital models. We segmented illustrative CT studies of the lumbar and cervical spine to create 3D models and then printed them using a consumer 3D printer and a professional 3D printing service. We also included downloadable versions of the models in an interactive eBook and platform-independent web viewer. We then provided these educational materials to residents with a pretest and posttest to assess efficacy. The "Spine Procedures in 3D" eBook has been downloaded 71 times as of October 5, 2016. All models used in the book are available for download and printing. Regarding test results, the mean exam score improved from 70 to 86%, with the most dramatic improvement seen in the least experienced trainees. Participants reported increased confidence in performing lumbar punctures after exposure to the material. We demonstrate the value of 3D models, both digital and printed, in learning spine procedures. Moreover, 3D printing and modeling is a rapidly expanding field with a large potential role for radiologists. We have detailed our process for creating and sharing 3D educational materials in the hopes of motivating and enabling similar projects.

  3. Revisiting Rebound Effects from Material Resource Use. Indications for Germany Considering Social Heterogeneity

    Johannes Buhl

    2014-02-01

    Full Text Available In contrast to the original investigation by William Stanley Jevons, compensations of energy savings due to improved energy efficiency are mostly analyzed by providing energy consumption or greenhouse gas emissions. In support of a sustainable resource management, this paper analyzes so-called rebound effects based on resource use. Material flows and associated expenditures by households allow for calculating resource intensities and marginal propensities to consume. Marginal propensities to consume are estimated from data of the German Socio-Economic Panel (SOEP in order to account for indirect rebound effects for food, housing and mobility. Resource intensities are estimated in terms of total material requirements per household final consumption expenditures along the Classification of Individual Consumption according to Purpose (COICOP. Eventually, rebound effects are indicated on the basis of published saving scenarios in resource and energy demand for Germany. In sum, compensations due to rebound effects are lowest for food while the highest compensations are induced for mobility. This is foremost the result of a relatively high resource intensity of food and a relatively low resource intensity in mobility. Findings are provided by giving various propensity scenarios in order to cope with income differences in Germany. The author concludes that policies on resource conservation need to reconsider rebound effects under the aspect of social heterogeneity.

    Scherer, Carolynn P.; Bushlya, Anatoly V.; Efimenko, Vladimir F.; Ilyanstev, Anatoly; Regoushevsky, Victor I.

    2010-01-01

    The condition of a nuclear material control and accountability system (MC and A) and its individual components, as with any system combining technical elements and documentation, may be characterized through an aggregate of values for the various parameters that determine the system's ability to perform. The MC and A system's status may be functioning effectively, marginally or not functioning based on a summary of the values of the individual parameters. This work included a review of the following subsystems, MC and A and Detecting Material Losses, and their respective elements for the material control and accountability system: (a) Elements of the MC and A Subsystem - Information subsystem (Accountancy/Inventory), Measurement subsystem, Nuclear Material Access subsystem, including tamper-indicating device (TID) program, and Automated Information-gathering subsystem; (b) Elements for Detecting Nuclear Material Loses Subsystem - Inventory Differences, Shipper/receiver Differences, Confirmatory Measurements and differences with accounting data, and TID or Seal Violations. In order to detect the absence or loss of nuclear material there must be appropriate interactions among the elements and their respective subsystems from the list above. Additionally this work includes a review of regulatory requirements for the MC and A system component characteristics and criteria that support the evaluation of the performance of the listed components. The listed components had performance testing algorithms and procedures developed that took into consideration the regulatory criteria. The developed MC and A performance-testing procedures were the basis for a Guide for MC and A Performance Testing at the material balance areas (MBAs) of State Scientific Center of the Russian Federation - Institute for Physics and Power Engineering (SSC RF-IPPE).

  5. The ideal usage of sustainable materials and local resources of the interior space design in Jordan

    Fahmi Hussien, Mayyadah [Department of Interior Design, Faculty of Architect and Art, Petra University (Jordan)], Email: Mayada19732004@yahoo.com

    2011-07-01

    A large amount of waste is generated by buildings over their life cycle, from construction and operation to destruction. Sustainable design principles and recycling programs in buildings can help moderate this waste. The simplest way is directly through the materials used in the building's construction. The materials and resources used should focus on the health and productivity consequences for the building's inhabitants and its environmental, social and economic impacts. This aim of this study is to make certain recommendations with respect to the use of sustainable building materials and resources in indoor spaces in Jordan. A general overview of collection and storage of recyclable materials, waste management, material reuse, and green and rapidly renewable materials is given. Sustainable material usage in the elements of interior design in Jordan is also discussed in two case studies. A set of indicators is proposed which identify the ideal sustainable materials and resources for use in interior design in Jordan to provide a healthy living environment.

  6. Eight Tons of Material Footprint—Suggestion for a Resource Cap for Household Consumption in Finland

    Michael Lettenmeier

    2014-07-01

    Full Text Available The paper suggests a sustainable material footprint of eight tons, per person, in a year as a resource cap target for household consumption in Finland. This means an 80% (factor 5 reduction from the present Finnish average. The material footprint is used as a synonym to the Total Material Requirement (TMR calculated for products and activities. The paper suggests how to allocate the sustainable material footprint to different consumption components on the basis of earlier household studies, as well as other studies, on the material intensity of products, services, and infrastructures. It analyzes requirements, opportunities, and challenges for future developments in technology and lifestyle, also taking into account that future lifestyles are supposed to show a high degree of diversity. The targets and approaches are discussed for the consumption components of nutrition, housing, household goods, mobility, leisure activities, and other purposes. The paper states that a sustainable level of natural resource use by households is achievable and it can be roughly allocated to different consumption components in order to illustrate the need for a change in lifestyles. While the absolute material footprint of all the consumption components will have to decrease, the relative share of nutrition, the most basic human need, in the total material footprint is expected to rise, whereas much smaller shares than at present are proposed for housing and especially mobility. For reducing material resource use to the sustainable level suggested, both social innovations, and technological developments are required.

  12. The global resource balance table, an integrated table of energy, materials and the environment

    Tsuchiya, Haruki

    2013-01-01

    This paper introduces the Global Resource Balance Table (GRBT), which is an extension of the energy balance tables that expresses the relationships between energy, materials and the environment. The material division of the GRBT includes steel, cement, paper, wood and grain. In contrast, the environmental division of the GRBT includes oxygen, CO 2 and methane. The transaction division rows in the GRBT include production, conversion, end use and stock. Each cell of the GRBT contains the quantities of the respective resources that were generated or consumed. The relationships between the cells were constructed from the laws of conservation of the materials and energy. We constructed a GRBT for 2007 and discussed the increasing air temperature due to waste heat and the CO 2 equivalent from human breathing. The GRBT is a comprehensive integrated table that represents the resources that are consumed by human activities and is useful for energy and environmental studies. - Highlights: • We extended energy balance table and introduced Global Resource Balance Table. • It shows relationships between energy, materials and the environment. • The material division includes steel, cement, paper, wood and grain. • The environmental division includes oxygen, CO 2 and methane. • We discussed on waste heat and CO 2 emission by human breathing

  13. A materials selection procedure for sandwiched beams via parametric optimization with applications in automotive industry

    Aly, Mohamed F.; Hamza, Karim T.; Farag, Mahmoud M.

    2014-01-01

    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

  14. Raw material monitoring assists companies. German Mineral Resources Agency at BGR provides information on global developments in resource markets

    2016-01-01

    Germany is dependent on imports for its metalliferous natural resources. Although prices have been declining significantly in recent months, numerous raw materials such as platinum, cobalt and rare earth elements continue to be exposed to price and supply risks. To ensure that German industry can respond better to this situation in their procurement activities, the German Mineral Resources Agency (DERA) at BGR has developed a raw material monitoring system on behalf of the German government. DERA experts have con figured a screening method for the early identification of possible procurement risks. This is the platform which enables German companies to gain the specific advice they require. All of the most important information on this issue is bundled within DERA 's internet portal (www.deutsche-rohstoffagentur.de). BGR also provides its expertise in other important fields with great societal relevance. BGR has been advising the national commission on ''Storage of High-level Radioactive Waste'' since 2014. Due to their comprehensive research activities in the field of radioactive waste disposal, BGR scientists are important technical experts to which the commission can turn to for geological information and advice.

  15. Can Patients Comprehend the Educational Materials that Hospitals Provide about Common IR Procedures?

    Sadigh, Gelareh; Hawkins, C Matthew; O'Keefe, John J; Khan, Ramsha; Duszak, Richard

    2015-08-01

    To assess the readability of online education materials offered by hospitals describing commonly performed interventional radiology (IR) procedures. Online patient education materials from 402 hospitals selected from the Medicare Hospital Compare database were assessed. The presence of an IR service was determined by representation in the Society of Interventional Radiology physician finder directory. Patient online education materials about (i) uterine artery embolization for fibroid tumors, (ii) liver cancer embolization, (iii) varicose vein treatment, (iv) central venous access, (v) inferior vena cava (IVC) filter placement, (vi) nephrostomy tube insertion, (vii) gastrostomy tube placement, and (viii) vertebral augmentation were targeted and assessed by using six validated readability scoring systems. Of 402 hospitals sampled, 156 (39%) were presumed to offer IR services. Of these, 119 (76%) offered online patient education material for one or more of the eight service lines. The average readability scores corresponding to grade varied between the ninth- and 12th-grade levels. All were higher than the recommended seventh-grade level (P Reading Ease scores ranged from 42 to 69, corresponding with fairly difficult to difficult readability for all service lines except IVC filter and gastrostomy tube placement, which corresponded with standard readability. A majority of hospitals offering IR services provide at least some online patient education material. Most, however, are written significantly above the reading comprehension level of most Americans. More attention to health literacy by hospitals and IR physicians is warranted. Copyright © 2015 SIR. Published by Elsevier Inc. All rights reserved.

  16. Decision making model for the recovery of useful material resources from wastes

    Rising, K.H.; Jensen, G.A.; FitzPatrick, V.F.

    1982-06-01

    In the United States, many of the material resources necessary for energy production are imported. Strategic stockpiling of these resources has been a well-known method for reducing the economic and productivity impact of supply interruption in case of emergency. Another viable option is the recovery of valuable materials and recycle of useful products from wastes generated in energy production and industrial processing. The technical feasibility for recovery and recycle, including decontamination of nuclear-related materials, has been proven and demonstrated. The economic feasibility would depend on both the resale and strategic values of the material, the saving from reusing rather than disposing of the material, the reclamation cost, and other factors that may influence the incentive for recovery and recycle. The purpose of the work presented in this paper is to develop a model to identify the economic and other incentives for the reclamation of useful material resources. Using available data to quantify factors such as strategic and resale values, reclamation cost and disposal cost saving, this model calculates the incentive value consisting of the above factors and selects the appropriate reclamation option. Because this model is empirical, there are limitations to its application. However, within the boundary where the model has been tested, it can be a useful tool for the decision maker to evaluate the economic feasibility of reclamation

  17. Nuclear fuel technology - Tank calibration and volume determination for nuclear materials accountancy - Part 1: Procedural overview

    2007-01-01

    Accurate determinations of volume are a fundamental component of any measurement-based system of control and accountability in a facility that processes or stores nuclear materials in liquid form. Volume determinations are typically made with the aid of a calibration or volume measurement equation that relates the response of the tank's measurement system to some independent measure of tank volume. The ultimate purpose of the calibration exercise is to estimate the tank's volume measurement equation (the inverse of the calibration equation), which relates tank volume to measurement system response. The steps carried out to acquire data for estimating the tank's calibration or volume measurement equation are collectively described as the process of tank calibration. This part of ISO 18213 describes procedures for tank calibration and volume determination for nuclear process tanks equipped with pressure-measurement systems for determining liquid content. Specifically, overall guidance is provided for planning a calibration exercise undertaken to obtain the data required for the measurement equation to estimate a tank's volume. The key steps in the procedure are also presented for subsequently using the estimated volume-measurement equation to determine tank liquid volumes. The procedures presented apply specifically to tanks equipped with bubbler probe systems for measuring liquid content. Moreover, these procedures produce reliable results only for clear (i.e. without suspended solids), homogeneous liquids that are at both thermal and static equilibrium. The paper elaborates on scope, physical principles involved, the calibration model, equipment required, a typical tank calibration procedure, calibration planning and pre-calibration activities, and volume determination.

    Behrouz Afshar-Nadjafi

    2014-01-01

    Full Text Available The preemptive Multimode resource investment problem is investigated. The Objective is to minimize the total renewable/nonrenewable resource costs and earliness-tardiness costs by a given project deadline and due dates for activities. In this problem setting preemption is allowed with no setup cost or time. The project contains activities interrelated by finish-start type precedence relations with a time lag of zero, which require a set of renewable and nonrenewable resources. The problem formed in this way is an NP-hard. A mixed integer programming formulation is proposed for the problem and parameters tuned genetic algorithm (GA is proposed to solve it. To evaluate the performance of the proposed algorithm, 120 test problems are used. Comparative statistical results reveal that the proposed GA is efficient and effective in terms of the objective function and computational times.

  4. Information systems for the materials management department: stand-alone and enterprise resource planning systems.

    2005-03-01

    Materials management information systems (MMISs) incorporate information tools that hospitals can use to automate certain business processes, increase staff compliance with these processes, and identify opportunities for cost savings. Recently, there has been a push by hospital administration to purchase enterprise resource planning (ERP) systems, information systems that promise to integrate many more facets of healthcare business. We offer this article to help materials managers, administrators, and others involved with information system selection understand the changes that have taken place in materials management information systems, decide whether they need a new system and, if so, whether a stand-alone MMIS or an ERP system will be the best choice.

  5. The effect of milling and postmilling procedures on the surface roughness of CAD/CAM materials.

    Mota, Eduardo Gonçalves; Smidt, Laura Nunes; Fracasso, Lisiane Martins; Burnett, Luiz Henrique; Spohr, Ana Maria

    2017-11-12

    The aim of this study was to evaluate the surface roughness and analyze the surface topography of five different CAD/CAM ceramics and one CAD/CAM composite resin for CEREC after milling and postmilling procedures. Blocks of the ceramics Mark II, IPS Empress CAD, IPS e.max CAD, Suprinity and Enamic, and blocks of the composite resin Lava Ultimate were milled at CEREC MCXL. Ten flat samples of each material were obtained. The surface roughness (Ra) test was performed before and after milling, crystallization, polishing, and glaze when indicated, followed by SEM and AFM analysis. Data were submitted to one-way ANOVA with repeated measures and the Tukey HSD test (α = 0.05). The milling step significantly increased the roughness of all the tested materials (P CAD and Suprinity) were more suitable to roughness than the other tested materials (P CAD/CAM materials, that is, fully sintered, should be only hand polished. The glaze step can be suppressed resulting in time saving. However, the glaze step in soft-milling lithium disilicate is imperative. © 2017 Wiley Periodicals, Inc.

  6. Analytical procedures for the determination of strontium radionuclides in environmental materials

    Harvey, B.R.; Ibbett, R.D.; Lovett, M.B.; Williams, K.J.

    1989-01-01

    As part of its statutory role in the authorisation, monitoring and research relating to radioactive wastes discharged into the aquatic environment, the Aquatic Environment Protection Division of the Directorate of Fisheries Research (DFR), Lowestoft routinely carries out analyses for a substantial number of radionuclides in a wide range of environmental materials. The Ministry of a Agriculture, Fisheries and Food has for many years required information about the concentrations of strontium radionuclides in waters, sediments and biological materials. There are not absolute standard methods for such radiochemical analysis; indeed none are required because methodology is continually developing. A very considerable amount of expertise has been developed in the analysis of radiostrontium at the Laboratory since the late 1950s, when detailed analysis first commenced, and the procedures described in this report have been developed and tested over a long period of time with a view to achieving the highest analytical quality. Full details of the practical, analytical and computational procedures, as currently used, are given in the Appendix. (author)

  7. Ancient DNA in historical parchments - identifying a procedure for extraction and amplification of genetic material.

    Lech, T

    2016-05-06

    Historical parchments in the form of documents, manuscripts, books, or letters, make up a large portion of cultural heritage collections. Their priceless historical value is associated with not only their content, but also the information hidden in the DNA deposited on them. Analyses of ancient DNA (aDNA) retrieved from parchments can be used in various investigations, including, but not limited to, studying their authentication, tracing the development of the culture, diplomacy, and technology, as well as obtaining information on the usage and domestication of animals. This article proposes and verifies a procedure for aDNA recovery from historical parchments and its appropriate preparation for further analyses. This study involved experimental selection of an aDNA extraction method with the highest efficiency and quality of extracted genetic material, from among the multi-stage phenol-chloroform extraction methods, and the modern, column-based techniques that use selective DNA-binding membranes. Moreover, current techniques to amplify entire genetic material were questioned, and the possibility of using mitochondrial DNA for species identification was analyzed. The usefulness of the proposed procedure was successfully confirmed in identification tests of historical parchments dating back to the 13-16th century AD.

  8. Evaluation of Acid Digestion Procedures to Estimate Mineral Contents in Materials from Animal Trials

    M. N. N. Palma

    2015-11-01

    Full Text Available Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios and one- or two-step digestion to estimate the concentration of calcium, phosphorus, magnesium, and zinc in samples of carcass, bone, excreta, concentrate, forage, and feces. Six procedures were evaluated: ratio of nitric to perchloric acid at 2:1, 3:1, and 4:1 v/v in a one- or two-step digestion. There were no direct or interaction effects (p>0.01 of nitric to perchloric acid ratio or number of digestion steps on magnesium and zinc contents. Calcium and phosphorus contents presented a significant (p0.01 calcium or phosphorus contents in carcass, excreta, concentrate, forage, and feces. Number of digestion steps did not affect mineral content (p>0.01. Estimated concentration of calcium, phosphorus, magnesium, and zinc in carcass, excreta, concentrated, forage, and feces samples can be performed using digestion solution of nitric to perchloric acid 4:1 v/v in a one-step digestion. However, samples of bones demand a stronger digestion solution to analyze the mineral contents, which is represented by an increased proportion of perchloric acid, being recommended a digestion solution of nitric to perchloric acid 2:1 v/v in a one-step digestion.

    Full Text Available The new Civil Procedure Code introduces several changes in the assumptions and judgment of admissibility of appeals, which directly influenced the conduct of current and future processes. This paper seeks to anticipate some of the difficulties, theoretical and practical, that legal professionals found in the application of the procedures established in the new code, bringing weightings should be considered for understanding the science base sought by the legislature. The low number of papers or literature on the subject highlights the need to better study the issue, which is related to the constitutional promise of reasonable duration of the process. In preparing the study, to achieve the proposed objectives, we used the theoretical research concerning the issue, consisting of the content analysis of doctrinal texts and legal norms.

    2018-03-20

    Internet growth has generated new types of services where the use of sensors and actuators is especially remarkable. These services compose what is known as the Internet of Things (IoT). One of the biggest current challenges is obtaining a safe and easy access control scheme for the data managed in these services. We propose integrating IoT devices in an access control system designed for Web-based services by modelling certain IoT communication elements as resources. This would allow us to obtain a unified access control scheme between heterogeneous devices (IoT devices, Internet-based services, etc.). To achieve this, we have analysed the most relevant communication protocols for these kinds of environments and then we have proposed a methodology which allows the modelling of communication actions as resources. Then, we can protect these resources using access control mechanisms. The validation of our proposal has been carried out by selecting a communication protocol based on message exchange, specifically Message Queuing Telemetry Transport (MQTT). As an access control scheme, we have selected User-Managed Access (UMA), an existing Open Authorization (OAuth) 2.0 profile originally developed for the protection of Internet services. We have performed tests focused on validating the proposed solution in terms of the correctness of the access control system. Finally, we have evaluated the energy consumption overhead when using our proposal.

    2016-09-01

    Full Text Available Exergy is applied to the Swedish energy supply system for the period 1970–2013. Exergy flow diagrams for the systems of electricity and district heating as well as for the total supply system of energy and material resources for 2012 are presented. The share of renewable use has increased in both electricity and district heat production. The resource use is discussed in four sectors: residential and service, transportation, industry and agriculture. The resource use is also analyzed with respect to exergy efficiency and renewable share. The total exergy input of energy and material resources amounts to about 2700 PJ of which about 530 PJ was used for final consumption in 2012. The results are also compared with similar studies. Even though the share of renewable resource use has increased from 42% in 1980 to 47% in 2012, poor efficiency is still occurring in transportation, space heating, and food production. A strong dependence on fossil and nuclear fuels also implies a serious lack of sustainability. A more exergy efficient technology and a higher renewable energy share are needed in order to become a more sustainable society.

This laboratory, the Trope Tank, is a facility for teaching, research, and creative collaboration and offers hardware (in working condition and set up for use from the 1970s, 1980s, and 1990s, including videogame systems, home computers, and an arcade cabinet. To aid in investigating the material history of texts, the lab has a small 19th century letterpress, a typewriter, a print terminal, and dot-matrix printers. Other resources include controllers, peripherals, manuals, books, and software on physical media. These resources are used for teaching, loaned for local exhibitions and presentations, and accessed by researchers and artists. The space is primarily a laboratory (rather than a library, studio, or museum, so materials are organized by platform and intended use. Textual information about the historical contexts of the available systems, and resources are set up to allow easy operation, and even casual use, by researchers, teachers, students, and artists.

  16. The good and bad of being fair: effects of procedural and interpersonal justice behaviors on regulatory resources.

    Johnson, Russell E; Lanaj, Klodiana; Barnes, Christopher M

    2014-07-01

    The justice literature has paid considerable attention to the beneficial effects of fair behaviors for recipients of such behaviors. It is possible, however, that exhibiting fair behaviors may come at a cost for actors. In this article, we integrate ego depletion theory with organizational justice research in order to examine the consequences of justice behaviors for actors. We used an experience-sampling method in a sample of managerial employees to examine the relations of performing procedural justice and interpersonal justice behaviors with subsequent changes in actors' regulatory resources. Our results indicate that procedural justice behaviors are draining, whereas interpersonal justice behaviors are replenishing for actors. Depletion, in turn, adversely affected the performance of citizenship behavior, and depletion mediated relations of justice behavior with citizenship. Furthermore, 2 traits that impact self-regulatory skills--extraversion and neuroticism--moderated the replenishing effects of engaging in interpersonal justice behaviors. We conclude by discussing implications and avenues for future research.

  17. The role of material/energy resources and dematerialisation in economic growth theories

    The nature of energy and material resources in an endogenous growth theory framework is clarified. This involves three modifications of the conventional theory. Firstly, multiple feedback mechanisms or 'growth engines' are identified. Secondly, a production function distinguishes between resource use, technical efficiency and value creation. Thirdly, the impact of the cost of production through demand on growth is accounted for. A formal model is analytically solved under a condition of a constant growth rate. Given model complexity, numerical experiments are performed as well, providing relevant insights to the academic and political debates on 'environmental Kuznets curves' and 'dematerialization'. 49 refs.

  20. Emission of biocides from treated materials: test procedures for water and air.

    Schoknecht, Ute; Wegner, Robby; Horn, Wolfgang; Jann, Oliver

    2003-01-01

    Methods for the determination of biocide emissions from treated materials into water and air were developed and tested in order to support a comparative ecological assessment of biocidal products. Leaching tests, experiments with simulated rain, extraction cleaning of carpets and emission chamber tests were performed with a series of treated materials. The experiments focused on the effect of changes in the procedure as well as characteristics of the specimens and demonstrate the suitability of the proposed methods for biocides of different product types. It was demonstrated that emissions of biocides into water can be compared on the basis of leaching tests in which the emission kinetics of the active ingredients are recorded. However, the water volume per surface area and the timetable for water changes have to be defined in such tests. Functions of flux rates related to time can be well described for inorganic compounds, whereas modelling of the data is more complicated for organic substances. Emission chamber tests using 20-litre and 23-litre glass exsiccators, originally developed to study volatile organic compounds, were successfully adapted for the investigation of the emission of biocides from treated materials which are usually semi volatile organic compounds. However test parameters and the method of analysis have to be adapted to the substances to be determined. Generally, it was found that the emission curves for the semi volatile organic compounds investigated differ from those of volatile organic compounds.

  4. FUNCTIONAL MODEL OF THE MATERIAL RESOURCES MANAGEMENT FOR PROJECTS OF THE CREATION OF NEW TECHNIQUES

    S. Yu. Danshyna

    2016-01-01

    Full Text Available The article is devoted to problem of material management arising in the implementation of projects for the development and creation (modernization of the new techniques. The uniqueness of the projects, their limit on the cost and time does not allow the use of traditional approaches to resource management. Such projects are often implemented in the development of companies; where it is not possible to abandon the traditional operating methods of management. The aim of the article is a formalization of the process of material management of projects, a description of its information flows for integrate into the project management practices and for improve the efficiency of material management. For the systematization of information arising from the material resources management, invited the set-theoretic representation of the management process. According with the requirements of project management standards were described the sets and defined rules of their transformation. Specification of the set-theoretic representation helped to establish the area and limits of the modelling process. Further decomposition process became the basis of the functional model, constructed in accordance with the methodology IDEF 0. A graphical representation of the model allows you to visualize the process at different levels of detail. For specification of issues related to the organization and promotion of material flow, were developed functional models of sub-processes and were described the identified data-flows. For the harmonization of process and project approaches formulated conditions for evaluating the efficiency of material management. The developed models can be the basis for designing the structure of companies, for regulation of their project activities, as well as for establishing an information system of management resources of projects.

  5. Estimation of Resource Productivity and Efficiency: An Extended Evaluation of Sustainability Related to Material Flow

    Pin-Chih Wang

    2014-09-01

    Full Text Available This study is intended to conduct an extended evaluation of sustainability based on the material flow analysis of resource productivity. We first present updated information on the material flow analysis (MFA database in Taiwan. Essential indicators are selected to quantify resource productivity associated with the economy-wide MFA of Taiwan. The study also applies the IPAT (impact-population-affluence-technology master equation to measure trends of material use efficiency in Taiwan and to compare them with those of other Asia-Pacific countries. An extended evaluation of efficiency, in comparison with selected economies by applying data envelopment analysis (DEA, is conducted accordingly. The Malmquist Productivity Index (MPI is thereby adopted to quantify the patterns and the associated changes of efficiency. Observations and summaries can be described as follows. Based on the MFA of the Taiwanese economy, the average growth rates of domestic material input (DMI; 2.83% and domestic material consumption (DMC; 2.13% in the past two decades were both less than that of gross domestic product (GDP; 4.95%. The decoupling of environmental pressures from economic growth can be observed. In terms of the decomposition analysis of the IPAT equation and in comparison with 38 other economies, the material use efficiency of Taiwan did not perform as well as its economic growth. The DEA comparisons of resource productivity show that Denmark, Germany, Luxembourg, Malta, Netherlands, United Kingdom and Japan performed the best in 2008. Since the MPI consists of technological change (frontier-shift or innovation and efficiency change (catch-up, the change in efficiency (catch-up of Taiwan has not been accomplished as expected in spite of the increase in its technological efficiency.

    Bio Design Facility is the specifically designed glass house for propagation, screening and analysis of high quality plant varieties developed through biotechnology or a combination of nuclear technology and biotechnology. High quality plant varieties especially genetically modified plants (GMO) require a special glass house facility for propagation and screening to isolate them from cross-pollinating with wild type varieties in surrounding ecosystem, and for carrying out evaluation of possible risks of the plants to human, animal and environment before they are proven safe for field trials or commercial release. This facility which was developed under the Ninth Malaysia Plan is classified as the Plant Containment Level 2 and is compliance with the bio safety regulations and guidance for the safe release of GMO according to Malaysian Bio safety Act 2007. Bio Design Facility is fully operational since 2010 and in 2012, it has also been certified as the glass house for post-entry quarantine by The Department of Agriculture. This paper summarizes the bio safety procedure for a safe, controlled and contained growing and evaluation of GMO in Bio Design Facility. This procedure covers the physical (containment and equipment's) and operational (including responsibility, code of practice, growing, decontamination and disposal of plant materials, emergency and contingency plan) aspects of the facility.

    2009-12-01

    To elucidate how dentists access knowledge sources when choosing adhesive agents for bonded restoration and whether these resources influenced the selection of materials. A national survey was carried out involving dentists in South Korea. The questionnaire included the status of the operator, clinical techniques, and materials. A total of 12,193 e-mails were distributed, 2632 were opened by recipients, and 840 responses were collected. For primary information resources in material selection, 55.8% (n = 469) of the responders mentioned continuing education. This selection criteria varied according to the working status of the clinician (p choice of bonding system was influenced by of the length of the career (p < 0.0001), and the preferred bonding systems differed according to the source of the information (p = 0.035). The popular bonding systems were not ranked according to the bonding strategy, but a preference was found for specific brands or manufacturers. To decrease the confusion of clinicians related to the selection of bonding materials, evidence-based guidelines need to be comprehensibly organized and efficiently approached in clinics.

RPC provides a language-independent protocol over a network interface; examples are RSOAP and Rserve. The local call stack provides a between-language mapping not over the network interface, but directly in computer memory; examples are R bindings, RPy, and languages sharing the Java Virtual Machine stack. This functionality provides strategies for sharing of software between Bio* projects, which can be exploited more often. Here, we present cross-language examples for sequence translation, and measure throughput of the different options. We compare calling into R through native R, RSOAP, Rserve, and RPy interfaces, with the performance of native BioPerl, Biopython, BioJava, and BioRuby implementations, and with call stack bindings to BioJava and the European Molecular Biology Open Software Suite. In general, call stack approaches outperform native Bio* implementations and these, in turn, outperform RPC-based approaches. To test and compare strategies, we provide a downloadable BioNode image with all examples, tools, and libraries included. The BioNode image can be run on VirtualBox-supported operating systems, including Windows, OSX, and Linux.

  14. A Systemic and Systematic Approach to the Development of a Policy Mix for Material Resource Efficiency

    Tomas Ekvall

    2016-04-01

    Full Text Available Increasing material use efficiency is important to mitigate future supply risks and minimize environmental impacts associated with the production of the materials. The policy mix presented in this paper aims to contribute to reducing the use of virgin metals in the EU by 80% by 2050 without significant shifting of burdens to other material resources, environmental impacts, or parts of the world. We used a heuristic framework and a systems perspective for designing the policy mix that combines primary instruments designed to increase material efficiency, recycling and substitution of materials (a materials tax, the extended producer responsibility, technical regulations, and environmental taxes and supportive instruments aimed to reduce barriers to implementing the primary instruments and to contribute towards the policy objectives (e.g., research and development support, and advanced recycling centers. Furthermore, instruments were designed so as to increase political feasibility: e.g., taxes were gradually increased as part of a green fiscal reform, and border-tax adjustments were introduced to reduce impacts on competitiveness. However, even in such a policy mix design ongoing ex-ante assessments indicate that the policy mix will be politically difficult to implement—and also fall short of achieving the 80% reduction target. Nonetheless, we suggest combining primary and supportive instruments into coherent and dynamic policy mixes as a promising step towards system reconfigurations for sustainability.

    2018-03-01

    Biomass waste generated from palm oil mill can be considered not only as the feedstock of renewable energy but also as the nutrient-rich resources to produce organic fertilizer. This study explored the appropriate resource management towards resilient palm oil production by applying material flow analysis. This study was conducted based on two palm oil mills in Lampung, Indonesia. The results showed that the empty fruit bunch (EFB) has the largest potential in terms of amount and energy among the biomass waste. The results also showed that the palm oil mills themselves had already self-managed their energy consumption thatwas obtained from palm kernel shell and palm press fiber. Finally, this study recommended the several utilization options of EFB for improvement of soil sustainability to contribute towards resilient palm oil production.

    Saccharide materials have been used for centuries as binding media, to paint, write and illuminate manuscripts and to apply metallic leaf decorations. Although the technical literature often reports on the use of plant gums as binders, actually several other saccharide materials can be encountered in paint samples, not only as major binders, but also as additives. In the literature, there are a variety of analytical procedures that utilize GC-MS to characterize saccharide materials in paint samples, however the chromatographic profiles are often extremely different and it is impossible to compare them and reliably identify the paint binder. This paper presents a comparison between two different analytical procedures based on GC-MS for the analysis of saccharide materials in works-of-art. The research presented here evaluates the influence of the analytical procedure used, and how it impacts the sugar profiles obtained from the analysis of paint samples that contain saccharide materials. The procedures have been developed, optimised and systematically used to characterise plant gums at the Getty Conservation Institute in Los Angeles, USA (GCI) and the Department of Chemistry and Industrial Chemistry of the University of Pisa, Italy (DCCI). The main steps of the analytical procedures and their optimisation are discussed. The results presented highlight that the two methods give comparable sugar profiles, whether the samples analysed are simple raw materials, pigmented and unpigmented paint replicas, or paint samples collected from hundreds of centuries old polychrome art objects. A common database of sugar profiles of reference materials commonly found in paint samples was thus compiled. The database presents data also from those materials that only contain a minor saccharide fraction. This database highlights how many sources of saccharides can be found in a paint sample, representing an important step forward in the problem of identifying polysaccharide binders in

  19. Technical procedures for water resources, Deaf Smith County site, Texas: Volume 2: Environmental Field Program: Final draft

    1987-08-01

    This volume contains the following Technical Procedures pursuant to the Water Resources Site Study Plan operation of a Playa Lake conductivity monitoring station and processing of data from a Playa Lake conductivity monitoring station. This procedure defines steps and methods for the installation, operation, and maintenance of the Playa Lake conductivity monitoring stations. Conductivity measurements will be taken at six playa lakes in the site study area to record changes in total dissolved solids as a function of stage. Playa lake conductivity and stage (volume) measurements will be used, in conjunction with other water quality data collected at the Playa Lake and precipitation stations, to determine the mass of dissolved solids entering and leaving the playas. This baseline information on the pollutant mass balance of the playas will be used to assess potential changes in playa lake water quality and the magnitude of those changes due to site development. The pollutant mass balances will also be used on determining the source of pollutants. 2 refs., 5 figs

    Jayachandra, A; Aggarwal, Vivek; Kumar, Sandeep; Nagesh, I V

    2018-04-01

    Cardiology interventions in peripheral hospitals is a challenging task where cardiologist have to fight against time and limited resources. Most of the sudden cardiac deaths occur due to arrhythmia and heart blocks/sinus node dysfunction. Our study is a single peripheral center experience of cardiac devices implantation using a 'C' Arm. The aim of this study was to post procedural complications of cardiac implants done in aresource limited setting under 'C' arm. This study is done at a peripheral cardiology center with no cardiac catheterization laboratory (CCL) facilities. Consecutive patients reporting to cardiology center, between Jan 2015 and Oct 2016, with a definite indication for cardiac device implant were included in the study. All the procedure of implantation was done in the operation theatre under 'C' arm under local anesthesia with continuous cardiac monitoring and critical care back up. Total 58 device implantations were done from Jan 2015 to Oct 2016. The mean age of the patients was 67.15 ± 10.85 years. Males constituted almost two third (68.9%) of patients. The commonest indication for device implantation was sinus node dysfunction in 60.34% followed by complete heart block in 25.86% and ventricular tachycardia in 12.06%. No post procedure infection was observed in our study. Device implantation constitute a major group of life saving interventions in cardiology practice. Our study has emphasised that when appropriate aseptic measures are taken during device implantation at peripheral centres, the complications rate are comparable to interventions done at advance cardiac centres.

  2. Resource efficiency of urban sanitation systems. A comparative assessment using material and energy flow analysis

    Meinzinger, Franziska

    2010-07-01

    Within the framework of sustainable development it is important to find ways of reducing natural resource consumption and to change towards closed-loop management. As in many other spheres increased resource efficiency has also become an important issue in sanitation. Particularly nutrient recovery for agriculture, increased energy-efficiency and saving of natural water resources, can make a contribution to more resource efficient sanitation systems. To assess the resource efficiency of alternative developments a systems perspective is required. The present study applies a combined cost, energy and material flow analysis (ceMFA) as a system analysis method to assess the resource efficiency of urban sanitation systems. This includes the discussion of relevant criteria and assessment methods. The main focus of this thesis is the comparative assessment of different systems, based on two case studies; Hamburg in Germany and Arba Minch in Ethiopia. A range of possible system developments including source separation (e.g. diversion of urine or blackwater) is defined and compared with the current situation as a reference system. The assessment is carried out using computer simulations based on model equations. The model equations not only integrate mass and nutrient flows, but also the energy and cost balances of the different systems. In order to assess the impact of different assumptions and calculation parameters, sensitivity analyses and parameter variations complete the calculations. Based on the simulations, following general conclusions can be drawn: None of the systems show an overall benefit with regard to all investigated criteria, namely nutrients, energy, water and costs. Yet, the results of the system analysis can be used as basis for decision making if a case-related weighting is introduced. The systems show varying potential for the recovery of nutrients from (source separated) wastewater flows. For the case study of Hamburg up to 29% of the mineral

    Extractive resources are primary source materials used for building infrastructure such as roads, ports, airports, bridges, railways, factories, hospitals, schools and homes. The Policy seeks to protect those essential and finite construction materials for future and existing extraction purposes. Population increases in south-east Queensland the upgrading of rail and port facilities to export coal and other minerals will form a major part in the expansion of extractive industry. Over $4 billion has been committed by the Government and industry to coal infrastructure developments such as upgrades at RG Tanna, Barney Point and the proposed Wiggins Island coal terminals at Gladstone, the Dalryample Bay and Hay Point terminals near Mackay and the Abbot Point coal terminal near Bower. The new Bauhinia regional railway will service the Rolleston coal mines.

    Kunii, Katsuhiko; Gonda, Mayuki; Ikeda, Kiyoshi; Nagaya, Shun; Itabashi, Keizo; Nakajima, Hidemitsu; Mineo, Yukinobu

    2011-01-01

    The Library of the Japan Atomic Energy Agency (JAEA) has developed two Japanese literature materials of bibliographic tools based on the International Nuclear Information System (INIS) of the IAEA which contains over 3.3 million records of 127 countries and 24 international organizations. These materials have been elaborated by appropriately designating Japanese terminology of nuclear field corresponding with English terminology or vice versa. One is 'Transliterated Japanese journal title list' and the other is 'INIS Thesaurus in Japanese'. While the former is served as a reference that enables users to access articles of Japanese journals better matching their needs, the latter is served as a dictionary to bridge the gap on nuclear field terminologies between over 30,000 English terms and Japanese terms which correspond with those in a semantic manner. The application of those materials to the INIS's full text collection over 280,000 of technical reports, proceedings etc. as an archive is helpful for enhancement of human resource development. The authors describe the effectiveness of those INIS-based materials with bibliographic references of Fukushima Daiichi NPS accident. (author)

  8. Japanese experiences in human resources development in the nuclear fields and proposal on procedure of the 1st seminar

    Murao, Yoshio

    2000-01-01

    The Atomic Energy Basic Act was enforced in 1956. The law prescribed establishment of the Atomic Energy Commission (establishment of the Nuclear Safety Commission was added in 1978), definition of administrative bodies for nuclear fuel materials and reactors and radiation protection, and necessary regulatory laws. The law also prescribed establishment of a national nuclear center for R and D and human resources development, i.e. Japan Atomic Energy Research Institute (JAERI) was established in 1956. The Nuclear Technology and Education Center (NuTEC) RI school was opened in 1958. Establishments of Power Reactor and Nuclear Fuel Development Corporation and National Institute of Radiological Science were in 1956 and 1957, respectively. In universities, nuclear facilities were constructed for supplying young human resources based on decision by Ministry of Education after 1961. The foundation of Japan Atomic Energy Power Co. (JAPCO) was in 1957. In the NuTEC, a variety of training courses had been prepared and carried out to meet the requirements of the nuclear community. Many leaders and experts had been produced and they worked for development of nuclear infrastructure in Japan. International training programs were started in 1985 and the experiences were applied for helping Asian countries to develop the manpower for nuclear infrastructure. Japanese safety actions for nuclear technology had strongly depended on that of USA. Therefore, much efforts on safety evaluation and phenomenological understanding are necessary in Japan. Recent tendency is changed from development-minded approach to safety-minded approach and is focused more on efforts to get public consent on nuclear energy. However, Japanese experiences will be useful for developing human resources in other countries. The NuTEC of JAERI will operate the seminar once a year. The seminar will be implemented; to get mutual recognition on present status and problems of regional countries by gathering information

    2014-01-01

    Background Protein-losing enteropathy (PLE) is a disorder characterized by abnormal and often profound enteric protein loss. It’s relatively uncommon complication of Fontan and other complex congenital heart disease (CCHD) procedures. Because of the complexity and rarity of this disease process, the pathogenesis and pathophysiology of protein-losing enteropathy remain poorly understood, and attempts at treatment seldom yield long-term success. Aim of presentation is to describe single centre experience in diagnosis, evaluation, management and treatment of children with protein-losing enteropathy after Fontan and other CCHD procedures in the current era and in centre with limited human and technical resources, follows with a comprehensive review of protein-losing enteropathy publications, and concludes with suggestions for prevention and treatment. Material and methodology Retrospectively we analyzed patients with CCHD and protein-losing enteropathy in our institution, starting from January 2000 to December 2012. The including criteria were age between two and 17 years, to have a complex congenital heart disease and available complete documentation of cardiac surgery under cardiopulmonary bypass. Results Of all patients we evaluated 18 cases with protein-losing enteropathy, aged 6 to 19 years (mean 14±9); there were three children who had undergone screening procedure for D-transposition, one Tetralogy of Fallot, and remaining 14 patients had undergone Fontan procedures; (anatomic diagnosis are: six with tricuspid atresia, seven with d-transposition, double outlet right ventricle and pulmonary atresia and two with hypoplastic left heart syndrome). The diagnosis of protein-losing enteropathy was made at median age of 5.6 years, ranging from 13 months to 15 years. Diagnosis was made using alpha 1-antitrypsin as a gold marker in stool. By physical examination in 14 patients edema was found, in three ascites, and six patients had pleural effusion. Laboratory findings

  10. ECONOMIC AND LEGAL ASPECTS OF MANAGEMENT OF WASTES AND SECONDARY MATERIAL RESOURCES (ON THE EXAMPLE OF CONSTRUCTION COMPLEX

    Tskhovrebov Eduard Stanislavovich

    2018-05-01

    Full Text Available Subject: technical and economic processes and aspects of handling wastes and secondary material resources; stages of transition of anthropogenic object of environment to wastes and secondary material resources; technical possibility and economic feasibility of using secondary material resources as a secondary raw material for making products, providing energy, works, services. The problem of economy and rational use of material and power resources is relevant and significant within the limits of maintenance of a strategic course of Russia on innovative sustainable development. In this article, issues of actualization and harmonization of the regulatory and legal base in the field of management of wastes and secondary material resources are considered from the viewpoint of maintenance of minimization of waste formation and maximum use of secondary material resources in an industrial-economic cycle, provision of economic incentives for innovative activity in the given field. The actual multi-plan problem, chosen here as a topic of research, concerns regulations in management of wastes and secondary material resources in construction complex, in which economic, civil-law, ecological, social, industrial and legal relations are closely coordinated and define a subject of the present research. Production and consumption waste is a dangerous anthropogenic object of the environment but at the same time, it is a valuable secondary material resource. The non-use of wastes to be recycled as secondary raw materials for energy generation, production and, as a result, their increasing accumulation in the environment causes irreparable harm to natural objects and human health due to their dangerous properties. Research objectives: scientific and methodological substantiation of legal regulation, economic basis for formation of wastes and secondary material resources management system (on the example of construction complex and building materials industry

  11. Resource Use in Small Island States: Material Flows in Iceland and Trinidad and Tobago, 1961-2008.

    Krausmann, Fridolin; Richter, Regina; Eisenmenger, Nina

    2014-04-01

    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.

    2010-01-01

    The learning process mediated by information and communication technology has considerable importance in the current context. This study describes the evaluation of a WebQuest on the theme "Management of Material Resources in Nursing". It was developed in three stages: Stage 1 consisted of its pedagogical aspect, that is, elaboration and definition of content; Stage 2 involved the organization of content, inclusion of images and completion; Stage 3 corresponded to its availability to students. Results confirm the importance of information technology and information as instruments for a mediating teaching practice in the integration between valid knowledge and the complex and dynamic reality of health services. As a result of the students' favorable evaluation of the approximation with the reality of nursing work and satisfaction for performing the activity successfully, the WebQuest method was considered valid and innovating for the teaching-learning process.

  13. Materials and energy resources. Report of the research committee working party

    1976-01-01

    The Working Party has tried to assess the problems likely to stem from future scarcity of a number of important materials and how these interact with the simultaneous depletion of energy resources. The report examines in detail the likely areas of shortages, and their economic, social and political implications, and suggests the various choices for preventive or corrective action. In its recommendations it has delineated areas not only for research but for action by government and by professional and other bodies. The need is forseen for a nuclear power programme of possibly 35 GW(e) by the end of the century part of which could be from fast breeders. Uranium supplies would appear to be adequate only if fast breeders become available. Nuclear fusion is potentially a very large energy source but only for the distant future. (author)

    Full Text Available Objective: Social networking sites (SNS are emerging as an alternate teaching resource. The reach and access characteristics of SNS for a noninstitutional, academic blog in an Indian setting has not been documented and this manuscript aim to address this lacunae. Materials and Methods: A blog for oral histology, an integral basic dental subject and its Facebook promotional page was created. The access characteristics were observed using Google analytics. The Facebook promotional pages of the blog access characteristics are presented. Results: A total of 582 people visited the blog during the study period. Majority of them used Google Chrome from desktop/laptop to access the blog. There were 2723 page visits in all. Visitors from 36 countries and 99 cities across the globe accessed the blog. In all through Facebook, the promotional page reached 36,543 people. The total number of people engaged through Facebook promotion page was 10,757. Conclusion: Access characteristics of the noninstitutional, academic blog have been described for the first time in dentistry. The lessons learnt through this exercise would be helpful in designing e-mentoring courses as well promotional pages of such events in the future. The necessity of making the mentors and students to adapt to e-learning and digital learning resources before drawing such programs is highlighted.

  18. Ultra High-Performance Fiber-Reinforced Concrete (UHPFRC: a review of material properties and design procedures

    T. E. T. Buttignol

    Full Text Available ABSTRACT This paper does a review of the recent achievements on the knowledge of UHPFRC properties and in the development of design procedures. UHPFRC is defined as a new material, with unique properties (high ductility, low permeability, very high strength capacity in compression, higher toughness in comparison to conventional concrete. It is important to know both material and mechanical properties to fully take advantage of its outstanding properties for structural applications. However, since this is a new material, the current design codes are not well suited and should be reviewed before being applied to UHPFRC. In the first part, the following material properties are addressed: hydration process; permeability; fibers role; mix design; fiber-matrix bond properties workability; mixing procedure; and curing. In the second part, the mechanical properties of the material are discussed, together with some design recommendations. The aspects herein examined are: size effect; compressive and flexural strength; tensile stress-strain relation; shear and punching shear capacity; creep and shrinkage; fracture energy; steel bars anchorage and adherence. Besides, the tensile mechanical characterization is described using inverse analysis based on bending tests data. In the last part, material behavior at high temperature is discussed, including physical-chemical transformations of the concrete, spalling effect, and transient creep. In the latter case, a new Load Induced Thermal Strain (LITS semi-empirical model is described and compared with UHPC experimental results.

  19. Determining the suitability of materials for disposal at sea under the London Convention 1972: A radiological assessment procedure

    2003-10-01

    on conducting specific assessments to determine whether candidate materials for disposal at sea contained de minimis levels of radioactivity. This report contains guidance on performing specific assessments of candidate materials to determine whether the materials are de minimis in the meaning of the London Convention 1972. It follows the guidelines adopted by the Twenty-first Consultative Meeting of the London Convention 1972 that incorporate a Stepwise Evaluation Procedure for screening candidate material to determine if it can be treated as 'non-radioactive' (i.e. de minimis) under the Convention. Material that cannot be readily defined as de minimis on the basis of Steps 1 to 5 of the Stepwise Evaluation Procedure require a specific assessment at Step 6. Such an assessment is the subject of this report. The assessment process described in this report is based on an inherently conservative procedure consistent with the precautionary approach, provided for under the London Convention 1972. Its purpose is to ensure the use of conservative models and cautious assumptions that result in the overestimation of the doses due to candidate materials that might be disposed of at sea in near coastal waters under de minimis provisions. Accordingly, the radiological consequences of disposal at sea of de minimis materials in other areas of the continental shelf and deeper waters will result in much lower radiation exposures than those considered here. It must be stressed that any candidate materials designated as de minimis must comply with all other provisions of the Convention. Section 2 provides a summary of the Stepwise Evaluation Procedure as detailed in the guidelines and background information necessary to understand the context of this guidance. Section 3 describes in detail a procedure to conduct the specific radiological assessment of the disposal of a candidate material. It contains a schematic diagram illustrating the specific assessment process and components of

  1. Episodic encoding in normal aging: attentional resources hypothesis extended to musical material.

    Blanchet, Sophie; Belleville, Sylvie; Peretz, Isabelle

    2006-01-01

    The goal of the present study was to examine age-related changes in musical episodic memory for novel tunes. This was conducted by manipulating the encoding condition in a recognition paradigm. After receiving memory instructions (intentional condition), older and younger participants obtained equivalent hits. In contrast, when intentional encoding was accompanied by a dancing judgment (dancing + intentional condition), the recognition performance of the older persons was severely impaired. Impaired recognition was also found when participants only judged the excerpts without being instructed to memorize them (dancing judgment condition). Although older participants demonstrated a preserved ability to perform the dancing judgment on its own, this ability was not optimal and likely precluded the initiation of more elaborate encoding strategies. These results suggest that asking older persons to divide their attention in the study phase reduces the quality of their musical encoding. Given this extension to musical material, we discuss the notion that the age-related attentional resource decline appears to be domain-general rather than specific to verbal material.

    The underground exploration of the salt-mine Gorleben has to be permitted according to sec. 126 para. 3, 51 et seq. Federal Mining Act. There is, however, no need for carrying out a nuclear law procedure for the official approval of the plan because the construction of the exploration mine does not represent the construction of a final storage facility. The operation of exploration measures does not create legally relevant prejudices for procedures of the official approval of the plan according to Atomic Energy Law. (HP) [de

  4. Evaluation of some procedures relevant to the determination of trace elemental components in biological materials by destructive neutron activation analysis

    Berry, D.L.

    1979-01-01

    The development of a simplified procedure for the analysis of biological materials by destructive neutron activation analysis (DNAA) is described. The sample manipulations preceding gamma ray assay were investigated as five specific stages of processing: (1) pre-irradiation treatment; (2) sample irradiation; (3) removal of the organic matrix; (4) removal of interfering radioactivities; and (5) concentration and separation of analyte activities. Each stage was evaluated with respect to susceptibility to sample contamination, loss of trace elemental components, and compatibility with other operations in the overall DNAA procedures. A complete DNAA procedure was proposed and evaluated for the analysis of standard bovine liver and blood samples. The DNAA system was effective for the determination of As, Cu, Fe, Hg, Mo, Rb, Sb, Se, and Zn without yield determinations and with a minimum turn-around time of approximately 3 days

    The development of a simplified procedure for the analysis of biological materials by destructive neutron activation analysis (DNAA) is described. The sample manipulations preceding gamma ray assay were investigated as five specific stages of processing: (1) pre-irradiation treatment; (2) sample irradiation; (3) removal of the organic matrix; (4) removal of interfering radioactivities; and (5) concentration and separation of analyte activities. Each stage was evaluated with respect to susceptibility to sample contamination, loss of trace elemental components, and compatibility with other operations in the overall DNAA procedures. A complete DNAA procedure was proposed and evaluated for the analysis of standard bovine liver and blood samples. The DNAA system was effective for the determination of As, Cu, Fe, Hg, Mo, Rb, Sb, Se, and Zn without yield determinations and with a minimum turn-around time of approximately 3 days.

  6. Evaluation of solution procedures for material and/or geometrically nonlinear structural analysis by the direct stiffness method.

    Stricklin, J. A.; Haisler, W. E.; Von Riesemann, W. A.

    1972-01-01

    This paper presents an assessment of the solution procedures available for the analysis of inelastic and/or large deflection structural behavior. A literature survey is given which summarized the contribution of other researchers in the analysis of structural problems exhibiting material nonlinearities and combined geometric-material nonlinearities. Attention is focused at evaluating the available computation and solution techniques. Each of the solution techniques is developed from a common equation of equilibrium in terms of pseudo forces. The solution procedures are applied to circular plates and shells of revolution in an attempt to compare and evaluate each with respect to computational accuracy, economy, and efficiency. Based on the numerical studies, observations and comments are made with regard to the accuracy and economy of each solution technique.

    Pugh, T.D.; Greenfield, M.B.; MacKenzie, J.; Meijer, R.J. de

    1992-01-01

    Laboratory facilities and apparatus have been constructed to measure radon exhalation from, and radon permeability through, various construction materials. This phase of the project has focused on development of test apparatus and evaluation of instrumentation. Results indicate significant spatial variability in the radon permeability of polyethylene, even when all test samples were selected from the same roll of material, and when no visible differentiation could be made regarding sample quality. Implications for code enforcement are described, and recommendations are offered for refinement of equipment and the measurement process, prioritization of future materials testing, and specific building code provisions, based on our results

  13. Developing Ultra-small Scale Mechanical Testing Methods and Microstructural Investigation Procedures for Irradiated Materials

    Hosemann, Peter; Kaoumi, Djamel

    2018-04-02

    Nuclear materials are an essential aspect of nuclear engineering. While great effort is spent on designing more advanced reactors or enhancing a reactor’s safety, materials have been the bottleneck of most new developments. The designs of new reactor concepts are driven by neutronic and thermodynamic aspects, leading to unusual coolants (liquid metal, liquid salt, gases), higher temperatures, and higher radiation doses than conventional light water reactors have. However, any (nuclear) engineering design must consider the materials used in the anticipated application in order to ever be realized. Designs which may look easy, simple and efficient considering thermodynamics or neutronic aspects can show their true difficulty in the materials area, which then prevents them from being deployed. In turn, the materials available are influencing the neutronic and thermodynamic designs and therefore must be considered from the beginning, requiring close collaborations between different aspects of nuclear engineering. If a particular design requires new materials, the licensing of the reactor must be considered, but licensing can be a costly and time consuming process that results in long lead times to realize true materials innovation. Extensive materials evaluation and irradiation campaigns need to be conducted in order to introduce a new material in a nuclear system. For licensing purposes, standard materials testing is key. However, basic scientific studies on new materials or even already used materials have the potential to accelerate the process of materials development or foster predictability of materials that are already in service and therefore are essential in order not to face difficulties later in the development or service stage. Therefore a combination of engineering scale materials evaluation as well as basic scientific understanding of the materials property changes under service condition is key to address potential issues in the process.

  14. A study of the material accountancy procedure at the uranium enrichment facility

    Shirahashi, J.; Akiba, M.; Omae, M.

    1984-01-01

    This paper describes an evaluation of material accountancy based on total uranium (U element MUF) to detect diversions of significant quantity in the uranium enrichment facility operating at a stated maximum enrichment level of 5%. Verification that material production is within the declared enrichment can be achieved by the inspection activities associated with limited - frequency unannounced access (LFUA) to cascade areas as treated extensively in HSP. According to the experience of the material accountancy at our facility, the reduction of the material accountancy capability by changing from U-235 isotope MUF to U element MUF is only about half. However, still the U element MUF approach can meet the current IAEA detection goals for the up to about 1000 tswu/a plant

  16. Systematic review of "filling" procedures for lip augmentation regarding types of material, outcomes and complications.

    San Miguel Moragas, Joan; Reddy, Rajgopal R; Hernández Alfaro, Federico; Mommaerts, Maurice Y

    2015-07-01

    The ideal lip augmentation technique provides the longest period of efficacy, lowest complication rate, and best aesthetic results. A myriad of techniques have been described for lip augmentation, but the optimal approach has not yet been established. This systematic review with meta-regression will focus on the various filling procedures for lip augmentation (FPLA), with the goal of determining the optimal approach. A systematic search for all English, French, Spanish, German, Italian, Portuguese and Dutch language studies involving FPLA was performed using these databases: Elsevier Science Direct, PubMed, Highwire Press, Springer Standard Collection, SAGE, DOAJ, Sweetswise, Free E-Journals, Ovid Lippincott Williams & Wilkins, Willey Online Library Journals, and Cochrane Plus. The reference section of every study selected through this database search was subsequently examined to identify additional relevant studies. The database search yielded 29 studies. Nine more studies were retrieved from the reference sections of these 29 studies. The level of evidence ratings of these 38 studies were as follows: level Ib, four studies; level IIb, four studies; level IIIb, one study; and level IV, 29 studies. Ten studies were prospective. This systematic review sought to highlight all the quality data currently available regarding FPLA. Because of the considerable diversity of procedures, no definitive comparisons or conclusions were possible. Additional prospective studies and clinical trials are required to more conclusively determine the most appropriate approach for this procedure. IV.

  17. Procedures for the determination of stable elements in construction materials from the nuclear reactors at Risoe National Laboratory

    Oestergaard, L.F.

    2006-03-01

    Methods for the accurate determination of stable isotopes of elements in construction materials with relevance to the work of the Danish Decommissioning have been developed. Prior to the analysis the elements of interest must be released from the construction materials and this is done with several different digestion methods. For the analysis of aluminium, lead, graphite and steels the samples are digested with mineral acids and microwave heating at increased pressures in a sealed teflon vessel. The aluminium, lead and steel are fully dissolved after the digestion procedure whereas graphite is chemically inert to the acid treatment used, but the elements of interest are extracted from the graphite quite efficiently. Concrete is digested with open-vessel heating in a Modblock TM digesting unit in a two step procedure involving 40% HF followed by 32% HNO 3 . The heavy barite concrete is first treated as the concrete samples but a large residue of poorly soluble sulphates (mainly BaSO 4 ) is left. The residue is fused with NaOH/Na 2 CO 3 at 575 deg. C and after some work up the product from the fusion is dissolved in dilute HNO 3 . After the release of the elements from the materials, the samples are analysed by ICP-OES and ICP-MS multi-element analysis. In general the following elements are of interest to DD; Ag, Ba, Ca, Co, Eu, Fe, Li, Mo, Nb, Ni, Sm, Th and U. For graphite, steel, concrete and heavy concrete, analytical methods for the determination of all 13 elements have been developed (except Ca in steel). For aluminium and lead methods for the determination of Ag, Co, Li, Nb, Ni and U, as well as Ba in the lead have been developed. When possible the methods have been verified against certified reference materials and calibration with standards additions and internal standard corrections have been used to correct for matrix effects most efficiently. The accuracy has also been checked with spikes when reference materials are not available. For the aluminium

    Falls represent a major care and cost problem to health and social services world-widely, since 50% of falls result in an injury. In this work, is proposed a methodology to evaluate protective pads materials and geometry performance, in order to reduce impact results in a fall event. Since the material properties and the pad geometry are the key factors to make the protection possible when a fall event occurs, our approach relies on the use of mechanical tests to evaluate the properties of the material and in the study of the pad response during a fall. For this, were used compression, tensile and instrumented falling weight tests, that allow a fully characterization of the materials that can be employed in the protective pads. Likewise, to gather precise information on falls events, in order to study the pad response during a fall, a set of laboratory fall trials were created using a camera-less inertial motion capture (mocap) system. This allow the acquisition of dynamic information of falls, namely acceleration and velocity that can be used to create a finite element analysis (FEA) model, where different segments from the human body can be evaluated when the protective pad is associated to it. Through the proposed methodology, different materials and pad geometries can be studied towards maximizing the performance of protection pads for falls. The mocap system allows the acquisition of fall data, and also the creation of a human body geometrical model, representative of the fall. From the mechanical trials, was showed that the spacer fabric embedded with silicone has the higher ability to reduce the peak force in case of impact when compared with all the other specimens. The compression and the tensile tests allow the mechanical definition of the material, and with this the material definition on the FEA model. Copyright © 2014 Elsevier Ltd. All rights reserved.

  19. Review of material recovery from used electric and electronic equipment-alternative options for resource conservation.

    Friege, Henning

    2012-09-01

    For waste from electric and electronic equipment, the WEEE Directive stipulates the separate collection of electric and electronic waste. As to new electric and electronic devices, the Restriction of Hazardous Substances (RoHS) Directive bans the use of certain chemicals dangerous for man and environment. From the implementation of the WEEE directive, many unsolved problems have been documented: poor collection success, emission of dangerous substances during collection and recycling, irretrievable loss of valuable metals among others. As to RoHS, data from the literature show a satisfying success. The problems identified in the process can be reduced to some basic dilemmas at the borders between waste management, product policy and chemical safety. The objectives of the WEEE Directive and the specific targets for use and recycling of appliances are not consistent. There is no focus on scarce resources. Extended producer responsibility is not sufficient to guarantee sustainable waste management. Waste management reaches its limits due to problems of implementation but also due to physical laws. A holistic approach is necessary looking at all branch points and sinks in the stream of used products and waste from electric and electronic equipment. This may be done with respect to the general rules for sustainable management of material streams covering the three dimensions of sustainable policy. The relationships between the players in the field of electric and electronic devices have to be taken into account. Most of the problems identified in the implementation process will not be solved by the current amendment of the WEEE Directive.

  20. A Simulation Model for Tensile Fracture Procedure Analysis of Graphite Material based on Damage Evolution

    Zhao Erqiang; Ma Shaopeng; Wang Hongtao

    2014-01-01

    Graphite material is generally easy to be damaged by the widely distributed micro-cracks when subjects to load. For numerically analyzing of the structure made of graphite material, the influences of the degradation of the material in damaged areas need to be considered. In this paper, an axial tension test method is proposed to obtain the dynamic damage evolution rule of the material. Using the degradation rule (variation of elastic modulus), the finite element model is then constructed to analyze the tensile fracture process of the L-shaped graphite specimen. An axial tension test of graphite is performed to obtain the stress-strain curve. Based on the variation of the measured curve, the damage evolution rule of the material are fitted out. A simulation model based on the above measured results is then constructed on ABAQUS by user subroutine. Using this simulation model, the tension failure process of L-shaped graphite specimen with fillet are simulated. The calculated and experimental results on fracture load are in good agreement. The damage simulation model based on the stress-strain curve of axial tensile test can be used in other tensile fracture analysis. (author)

  1. A procedure to obtain reliable pair distribution functions of non-crystalline materials from diffraction data

    Hansen, F.Y.; Carneiro, K.

    1977-01-01

    A simple numerical method, which unifies the calculation of structure factors from X-ray or neutron diffraction data with the calculation of reliable pair distribution functions, is described. The objective of the method is to eliminate systematic errors in the normalizations and corrections of the intensity data, and to provide measures for elimination of truncation errors without losing information about the structure. This is done through an iterative procedure, which is easy to program for computers. The applications to amorphous selenium and diatomic liquids are briefly reviewed. (Auth.)

  2. A Highly Sensitive Multicommuted Flow Analysis Procedure for Photometric Determination of Molybdenum in Plant Materials without a Solvent Extraction Step

    Felisberto G. Santos

    2017-01-01

    Full Text Available A highly sensitive analytical procedure for photometric determination of molybdenum in plant materials was developed and validated. This procedure is based on the reaction of Mo(V with thiocyanate ions (SCN− in acidic medium to form a compound that can be monitored at 474 nm and was implemented employing a multicommuted flow analysis setup. Photometric detection was performed using an LED-based photometer coupled to a flow cell with a long optical path length (200 mm to achieve high sensitivity, allowing Mo(V determination at a level of μg L−1 without the use of an organic solvent extraction step. After optimization of operational conditions, samples of digested plant materials were analyzed employing the proposed procedure. The accuracy was assessed by comparing the obtained results with those of a reference method, with an agreement observed at 95% confidence level. In addition, a detection limit of 9.1 μg L−1, a linear response (r=0.9969 over the concentration range of 50–500 μg L−1, generation of only 3.75 mL of waste per determination, and a sampling rate of 51 determinations per hour were achieved.

  6. Materialism.

    Melnyk, Andrew

    2012-05-01

    Materialism is nearly universally assumed by cognitive scientists. Intuitively, materialism says that a person's mental states are nothing over and above his or her material states, while dualism denies this. Philosophers have introduced concepts (e.g., realization and supervenience) to assist in formulating the theses of materialism and dualism with more precision, and distinguished among importantly different versions of each view (e.g., eliminative materialism, substance dualism, and emergentism). They have also clarified the logic of arguments that use empirical findings to support materialism. Finally, they have devised various objections to materialism, objections that therefore serve also as arguments for dualism. These objections typically center around two features of mental states that materialism has had trouble in accommodating. The first feature is intentionality, the property of representing, or being about, objects, properties, and states of affairs external to the mental states. The second feature is phenomenal consciousness, the property possessed by many mental states of there being something it is like for the subject of the mental state to be in that mental state.

    Abstract Iron based materials still represent a high percentage from metallic materials used in industry, in general, and in automotive industry, in particular. In this case we used a duplex process in order to obtain the FeMnSiAl experimental alloy for a more efficient use of various units. In the first stage iron, manganese, silicon and aluminum were melted and mixed together using arc melting technology and for the second stage the alloy was re-melt for homogeneity in an induction furnace. Chemical composition, after each melting step, was analyzed using EDS Bruker detector for various areas and microstructural characterization using SEM, VegaTescan LMH II with SE detector, equipment. This alloy is proposed as a metallic approach of mechanical dumpers used in automotive industry for low and medium impact contacts.

    2015-01-01

    Two approaches may be employed in the preparation of Reference Materials (RMs) for use in micro analytical techniques: placement of characterized micro artefacts in bulk materials and characterization of certain classes of individual particles in existing materials. In November 2013, a collaborative project was launched with the aim of adding information about such individual particles in existing RMs. The motivation behind this project was to investigate and characterize micro-artefacts present in certain commercially available RM, making them available and fit for use in safeguards and several other nuclear applications. The implementation and development of new techniques for particle characterization in bulk materials are also part of this project. The strategy for that approach includes the following steps: 1. Sample preparation: Dispersion of particles on stubs and planchets by an in-house shock-wave device. 2. Particle-of-Interest identification and characterization: (a) Fission Track (FT) route: Mosaic imaging of detectors containing FT stars; Applying automatic pattern recognition and localization of FT stars in detectors; Using Laser Micro-Dissection (LMD) for retrieval of individual particles; Preparation of sampled particles for SEM observation and other analytical techniques. (b) Alpha Track (αT) route: Direct particle identification and localization using position sensitive detectors (instrumental auto-radiography). (c) The advanced SEM route: Integration of analytical SEM techniques for characterization of individual particles of interest: EDS, mass spectrometry, FIB, micro-Raman. Preliminary results of the ongoing efforts will be reported. Utilization of these hyphenated techniques and instruments represents an innovative approach to particle characterization for Safeguards applications. (author)

    Celani John Nyide

    2016-12-01

    Full Text Available Material Flow Cost Accounting (MFCA is one of the Environmental Management Accounting (EMA tools that has been developed to enable environmentally and economically efficient material usage and thus improve resource efficiency. However, the use of this tool to improve resource efficiency in the South African hotel sector remains unknown. An exploratory study, qualitative in nature, was conducted using a single case study with embedded units approach. A Hotel Management Group that met the selection criteria formed part of this study. In-depth interviews were conducted with 10 participants and additional documents were analysed. The investigated hotels have developed technologies that provide an environmental account in both physical and monetary units which constitute the use of MFCA to improve resource efficiencies. However, the study established a number of factors that affect the implementation of MFCA by the hotel sector in a South African context

  12. Procedure to approximately estimate the uncertainty of material ratio parameters due to inhomogeneity of surface roughness

    Hüser, Dorothee; Thomsen-Schmidt, Peter; Hüser, Jonathan; Rief, Sebastian; Seewig, Jörg

    2016-01-01

    Roughness parameters that characterize contacting surfaces with regard to friction and wear are commonly stated without uncertainties, or with an uncertainty only taking into account a very limited amount of aspects such as repeatability of reproducibility (homogeneity) of the specimen. This makes it difficult to discriminate between different values of single roughness parameters. Therefore uncertainty assessment methods are required that take all relevant aspects into account. In the literature this is rarely performed and examples specific for parameters used in friction and wear are not yet given. We propose a procedure to derive the uncertainty from a single profile employing a statistical method that is based on the statistical moments of the amplitude distribution and the autocorrelation length of the profile. To show the possibilities and the limitations of this method we compare the uncertainty derived from a single profile with that derived from a high statistics experiment. (paper)

    2010-05-01

    The Materials and Fuels Complex (MFC) located in Bingham County at the Idaho National Laboratory (INL) in southeastern Idaho is considering several alternatives to upgrade wastewater systems to meet future needs at the facility. In April and May of 2010, the INL Cultural Resource Management Office conducted archival searches, archaeological field surveys, and coordination with the Shoshone-Bannock Tribes to identify cultural resources that may be adversely affected by the proposed construction and to provide recommendations to protect any resources listed or eligible for listing on the National Register of Historic Places. These investigations showed that one National Register-eligible archaeological site is located on the boundary of the area of potential effects for the wastewater upgrade. This report outlines protective measures to help ensure that this resource is not adversely affected by construction.

  15. A procedure for estimating site specific derived limits for the discharge of radioactive material to the atmosphere

    Hallam, J; Jones, J A

    1983-01-01

    Generalised Derived Limits (GDLs) for the discharge of radioactive material to the atmosphere are evaluated using parameter values to ensure that the exposure of the critical group is unlikely to be underestimated significantly. Where the discharge is greater than about 5% of the GDL, a more rigorous estimate of the derived limit may be warranted. This report describes a procedure for estimating site specific derived limits for discharges of radioactivity to the atmosphere taking into account the conditions of the release and the location and habits of the exposed population. A worksheet is provided to assist in carrying out the required calculations.

    Strontium, barium, rubidium, and cesium in selected, predominantly biological, reference materials (NIST 1515, 1547, 1549, 1566a, 1571, 1577b, 2704, CTA-OTL-1, and Bowen's Kale) were determined using neutron activation analysis (NAA) in two different analytical modes - instrumental NAA with epithermal neutrons (ENAA), and NAA with radiochemical group separation of Sr-Ba and Rb-Cs (RNAA). The ENAA mode was based on long-term (5 h) irradiation of samples in a Cd shielding. The RNAA procedure was based on long-term (20 h) irradiation of samples, their decomposition / dissolution by alkaline-oxidative fusion, and precipitation of Sr and Ba sulfates, and sorption of Rb and Cs onto ammonium phosphomolybdate (APM). Both methods provided element contents in the analyzed reference materials consistent with certified and/or literature values. (author)

    2016-08-01

    Full Text Available The aim of the article is to determine the status and main problems of the resource provision of Ukraine’s health care system and identify the most appropriate and relevant directions of improving the procedure for its formation and use in the context of the current social and economic transformations. The study considers indicators characterizing the status of funding expenditures on the functioning of the health system for the past 4 years, the plan for the current year and the forecast for the following one. This made it possible to make a conclusion about the budget model and residual principle of funding the branch; the insufficient amount of expenditures on health care; the inefficiency, illegality and irrationality of their implementation by the existing network of health care institutions; the low level of the state and regional control over the resource potential of Ukraine’s health care system. To overcome these negative trends and ensure the health system reform in accordance with the Strategy for Sustainable Development “Ukraine – 2020”, there considered a mechanism of state control over resources provision of the health care system, the implementation of which will improve the quality of health of the population, provide full access to health services, increase the level of funding and efficiency of using the resource potential of the health care system. There also proposed a number of measures which, in the authors’ opinion, will create sufficient conditions for improving the procedure of forming and using the branch resource potential.Prospects for further research are developing a mechanism for attracting additional sources to the branch funding, studying and adapting experience of leading countries of the world in reforming the health system, improving the classification of financial resources of health care institutions.

    Self-ion irradiation is widely used as a method to simulate neutron damage in reactor structural materials. Accelerator-based simulation of void swelling, however, introduces a number of neutron-atypical features which require careful data extraction and, in some cases, introduction of innovative irradiation techniques to alleviate these issues. We briefly summarize three such atypical features: defect imbalance effects, pulsed beam effects, and carbon contamination. The latter issue has just been recently recognized as being relevant to simulation of void swelling and is discussed here in greater detail. It is shown that carbon ions are entrained in the ion beam by Coulomb force drag and accelerated toward the target surface. Beam-contaminant interactions are modeled using molecular dynamics simulation. By applying a multiple beam deflection technique, carbon and other contaminants can be effectively filtered out, as demonstrated in an irradiation of HT-9 alloy by 3.5 MeV Fe ions.

  20. Beef, chicken and lamb fatty acid analysis--a simplified direct bimethylation procedure using freeze-dried material.

    Lee, M R F; Tweed, J K S; Kim, E J; Scollan, N D

    2012-12-01

    When fractionation of meat lipids is not required, procedures such as saponification can be used to extract total fatty acids, reducing reliance on toxic organic compounds. However, saponification of muscle fatty acids is laborious, and requires extended heating times, and a second methylation step to convert the extracted fatty acids to fatty acid methyl esters prior to gas chromatography. Therefore the development of a more rapid direct methylation procedure would be of merit. The use of freeze-dried material for analysis is common and allows for greater homogenisation of the sample. The present study investigated the potential of using freeze-dried muscle samples and a direct bimethylation to analyse total fatty acids of meat (beef, chicken and lamb) in comparison with a saponification procedure followed by bimethylation. Both methods compared favourably for all major fatty acids measured. There was a minor difference in relation to the C18:1 trans 10 isomer with a greater (Psaponification. However, numerically the difference was small and likely as a result of approaching the limits of isomer identification by single column gas chromatography.

    2011-12-01

    Full Text Available Purpose: This study investigates the distortion of geometry of catheters and anatomy in acquired U/S images, caused by utilizing various stand-off materials for covering a transrectal bi-planar ultrasound probe in HDR and LDR prostatebrachytherapy, biopsy and other interventional procedures. Furthermore, an evaluation of currently established waterbathbased quality assurance (QA procedures is presented. Material and methods: Image acquisitions of an ultrasound QA setup were carried out at 5 MHz and 7 MHz. The U/Sprobe was covered by EA 4015 Silicone Standoff kit, or UA0059 Endocavity balloon filled either with water or one ofthe following: 40 ml of Endosgel®, Instillagel®, Ultraschall gel or Space OAR™ gel. The differences between imageswere recorded. Consequently, the dosimetric impact of the observed image distortion was investigated, using a tissueequivalent ultrasound prostate phantom – Model number 053 (CIRS Inc., Norfolk, VA, USA. Results: By using the EA 4015 Silicone Standoff kit in normal water with sound speed of 1525 m/s, a 3 mm needleshift was observed. The expansion of objects appeared in radial direction. The shift deforms also the PTV (prostate inour case and other organs at risk (OARs in the same way leading to overestimation of volume and underestimationof the dose. On the other hand, Instillagel® and Space OAR™ “shrinks” objects in an ultrasound image for 0.65 mm and0.40 mm, respectively. Conclusions: The use of EA 4015 Silicone Standoff kit for image acquisition, leads to erroneous contouring of PTVand OARs and reconstruction and placement of catheters, which results to incorrect dose calculation during prostatebrachytherapy. Moreover, the reliability of QA procedures lies mostly in the right temperature of the water used foraccurate simulation of real conditions of transrectal ultrasound imaging.

  2. A theory of economic growth with material/energy resources and dematerialization. Interaction of three growth mechanisms

    The nature of energy and material resources in a non-optimizing growth theory framework is clarified. This involves two modifications of the conventional theory. Firstly, multiple feedback mechanisms or 'growth engines' are identified, such that the impact of the cost of production through demand on growth is accounted for. Secondly, a production function distinguishes between resource use, technical efficiency, and value creation. The resulting model is analytically solved under the condition of a constant growth rate. Given model complexity, numerical experiments are performed as well, providing relevant insights to the academic and political debates on 'environmental Kuznets curves' and 'dematerialization.'.

  3. Exploitation and use of raw materials resources for manufacturing nuclear fuels. Present and future

    Georgescu, Dan; Nica, Dan Bujor; Iuhas, Tiberius; Muntean, Ioan

    2002-01-01

    The nuclear fuel for Cernavoda Romanian nuclear power plant is based on natural uranium cycle implying mining, concentration-refining and UO 2 manufacturing. For the Uranium National Company securing the raw materials necessary for fuel element manufacturing implies the following sources: - from the production cumulated till the year 2001 in the Security and Consumption Stock; - from the current production of uranium ore. Romania posses two categories of deposits which ensure at present and in the future the uranium ore production: active deposits and production center at Crucea-Botusana; - deposits proposed for the exploitation activity at Tulghes - Grinties. Other two important centers of production in Banat and Bihor ceased the production since 1999 due to the deposit depletion. The uranium reserve of Romania is estimated to 9,233 tones in geological deposits of high confidence level plus 6,344 tones in resources still not searched. The medium- and long-term strategy of CNU to fructify the uranium reserves of Romania is in concordance with the current government policy and is based upon two major investments: - opening a new production unit at Tulghes-Grinties; - Refurbishment of plants R1 and E1. The main amount of uranium currently used for making the needed nuclear fuel comes today from the production center Crucea-Botusana. Here the exploitation is based mainly on pitchblende-rich deposits. Uranium ore processing and concentration is made at 'R' and 'E' plants at Feldioara able to ensure an annual capacity of 300 tones UO 2 . In the assesment of the amount of uranium needed in the nuclear fuel fabrication the degree of uranium recovery was also taken into account. The uranium supply implied by the new electro-nuclear plants to be installed till 2025 was evaluated by taking into account the future advanced fuel solutions, SEU and RU, what will diminish the natural uranium consumption to 55% and 66%, respectively. The price of nuclear fuel has been estimated

  4. The importance of material resources and qualified trainers in adult non-formal education and training centres in South Africa

    Mayombe, Celestin; Lombard, Antoinette

    2016-04-01

    Non-formal education and training (NFET) programmes in public and private centres in South Africa aim to meet the training needs of adults who have been deprived of formal education which would have fostered skills acquisition and access to employment earlier in their lives. The concern which informs this paper is that adults who face long-term unemployment due to a lack of marketable skills often remain unemployed after completing NFET programmes. The paper assesses the extent to which material and human resources have affected skills acquisition and graduate employment in KwaZulu-Natal, South Africa. The results show that material and human resource challenges in most public and some private centres have led to gaps in skills training. Programmes focus too strongly on academic credits and certificates and not enough on employment as an end goal. The authors argue that the existence of suitable training materials and qualified trainers with practical experience and specific technical skills constitutes favourable conditions ("enabling environments") for graduate employment. Without improvement in material and human resources, adult trainees will continue to experience difficulties integrating into the labour market, and the cycle of poverty and social exclusion will remain unbroken.

  5. Comparison of antimicrobial activities and compressive strength of alginate impression materials following disinfection procedure.

    2012-07-01

    This study investigated the effectiveness of disinfecting solution when incorporated into alginate powder instead of water against some microorganisms and on compressive strength of alginate. For measuring antimicrobial activity of alginate, 60 alginate specimens were prepared and divided into two groups: One with water incorporated in the mix (control) and the other with 0.2% chlorhexidine digluconate incorporated in the mix instead of water. The tested microorganisms were: gram +ve cocci, gram -ve bacilli and yeast (each group 10 samples). For measuring compressive strength, 20 specimens of alginate were divided into two groups: One with water incorporated in the mix (control) and the other with chlorhexidine incorporated in the mix. The statistical analysis of antimicrobial efficacy of alginate was performed with Mann-Whitney U-test, which revealed very high significant difference when comparing among groups (p 0.05). The incorporation of disinfecting agents into impression materials could serve an important role in dental laboratory infection control and it had no adverse effect on compressive strength of the hydrocolloid alginate. The risk of transmitting pathogenic microorganisms to dental laboratories via impression has been considered a topic of importance for a number of years.

    The magnitude of safety risks related to medications of the older adults has been evidenced by numerous studies, but less is known of how to manage and prevent these risks in different health care settings. The aim of this study was to coordinate resources for prospective medication risk management of home care clients ≥ 65 years in primary care and to develop a study design for demonstrating effectiveness of the procedure. Health care units involved in the study are from primary care in Lohja, Southern Finland: home care (191 consented clients), the public healthcare center, and a private community pharmacy. System based risk management theory and action research method was applied to construct the collaborative procedure utilizing each profession's existing resources in medication risk management of older home care clients. An inventory of clinical measures in usual clinical practice and systematic review of rigorous study designs was utilized in effectiveness study design. The new coordinated medication management model (CoMM) has the following 5 stages: 1) practical nurses are trained to identify clinically significant drug-related problems (DRPs) during home visits and report those to the clinical pharmacist. Clinical pharmacist prepares the cases for 2) an interprofessional triage meeting (50-70 cases/meeting of 2 h) where decisions are made on further action, e.g., more detailed medication reviews, 3) community pharmacists conduct necessary medication reviews and each patients' physician makes final decisions on medication changes needed. The final stages concern 4) implementation and 5) follow-up of medication changes. Randomized controlled trial (RCT) was developed to demonstrate the effectiveness of the procedure. The developed procedure is feasible for screening and reviewing medications of a high number of older home care clients to identify clients with severe DRPs and provide interventions to solve them utilizing existing primary care resources

  8. Supporting Instruction By Defining Conceptual Relevance Of Materials: Alignment Of Resources To An Earth Systems Framework

    Menicucci, A. J.; Bean, J. R.

    2017-12-01

    Environmental, geological, and climatological sciences are important facets of physical science education. However, it is often difficult for educators to acquire the necessary resources to facilitate content explanations, and demonstration of the conceptual links between individual lessons. The Understanding Global Change (UGC) Project at the University of California Museum of Paleontology (UCMP) at UC Berkeley is aligning new and existing Earth systems educational resources that are high-quality, interactive and inquiry based. Learning resources are organized by the UGC framework topics (Causes of Change, How the Earth System Works, and Measurable Changes), and focus on exploring topic relationships. Resources are currently aligned with both the UGC framework and the Next Generation Science Standards (NGSS), facilitating broad utility among K-16 educators. The overarching goal of the UGC Project is to provide the necessary resources that guide the construction of coherent, interdisciplinary instructional units. These units can be reinforced through system models, providing visual learning scaffolds for assessments of student content knowledge. Utilizing the central framework of UGC alleviates the long-standing problem of creating coherent instructional units from multiple learning resources, each organized and categorized independently across multiple platforms that may not provide explicit connections among Earth science subjects UGC topic cross listing of learning modules establishes conceptual links. Each resource is linked across several Earth system components, facilitating exploration of relationships and feedbacks between processes. Cross listed topics are therefore useful for development of broad picture learning goals via targeted instructional units. We also anticipate cultivating summaries of the explicit conceptual links explored in each resource from both current teachers and content specialists. Insructional units currated and aligned under the UGC

  9. The advantages of using standardized review procedures in certifying type B radioactive material packages

    Easton, E.P.; Faille, S.

    2004-01-01

    This paper presents the advantages of adopting well-documented standardized review practices for reviewing Type B package designs. The US experience using standardized review plans and guidance has shown them to be a valuable tool in achieving more consistent and efficient package reviews, in training and qualifying technical reviewers, and in enhancing public and industry understanding of the package certification process. In addition, the standardized review practices, as living documents, have proven to be an effective method of incorporating new technical advances into the review process, and have provided a vehicle to make that knowledge widely available to fellow reviewers, the public and industry. Canada implemented a new internal review process in early 2003 to standardize the review of applications for certification of Type B Packages. Based on the similarity of these approaches, the United States and Canada have started discussions on a A North American System for the unilateral approval of Type B (U) packages. This initiative is looking into how each country is currently reviewing transportation package applications to see if agreement can be reached on accepting Type B certifications on a reciprocal basis, i.e., without additional review. Based on the experience in Canada and the United States, the authors believe that the use of standardized review processes, coupled with the knowledge and experience resident in IAEA's Transportation Advisory Material (TS-G-1.1) and series of TECDOCS, could also be used to develop a standard internationally accepted review process that could enhance the acceptance of unilateral approvals for Type B packages

  10. Experimental and numerical investigations of a hydrogen-assisted laser-induced materials transfer procedure

    Toet, D.; Smith, P. M.; Sigmon, T. W.; Thompson, M. O.

    2000-01-01

    We present investigations of the mechanisms of a laser-induced transfer technique, which can be used for the spatially selective deposition of materials such as Si. This transfer is effected by irradiating the backside of a hydrogenated amorphous silicon film, deposited on a transparent substrate with an excimer laser pulse. The resulting release and accumulation of hydrogen at the film/substrate interface propels the silicon onto an adjacent receptor wafer. Time-resolved infrared transmission measurements indicate that the amorphous film is melted by the laser pulse and breaks into droplets during ejection. These droplets travel towards the receptor substrate and coalesce upon arrival. The transfer velocity increases as a function of fluence, the rate of increase dropping noticeably around the full melt threshold of the film. At this fluence, the transfer velocity reaches values of around 1000 m/s for typical films. Atomic force microscopy reveals that films transferred below the full melt threshold only partially cover the receptor substrate, while uniform, well-adhering films, which can be smoothed by subsequent laser irradiation, are obtained above it. Transfer of hydrogen-free Si films, on the other hand, does not occur until much higher fluences. The dynamics of the process have been simulated using a semiquantitative numerical model. In this model, hydrogen released from the melt front is instantaneously accumulated at the interface with an initial kinetic energy given by the melting temperature of Si and the enthalpy of solution. The resulting pressure accelerates the Si film, the dynamics of which are modeled using Newtonian mechanics, and the gas cools adiabatically as its kinetic energy is converted to the film's momentum. The results of the calculations are in good agreement with the experimental data. (c) 2000 American Institute of Physics

  12. Molten salt oxidation of mixed wastes: Separation of radioactive materials and Resource Conservation and Recovery Act (RCRA) materials

    Bell, J.T.; Haas, P.A.; Rudolph, J.C.

    1993-01-01

    The Oak Ridge National Laboratory (ORNL) is involved in a program to apply a molten salt oxidation (MSO) process to the treatment of mixed wastes at Oak Ridge and other Department of Energy (DOE) sites. Mixed wastes are defined as those wastes that contain both radioactive components, which are regulated by the atomic energy legislation, and hazardous waste components, which are regulated under the Resource Conservation and Recovery Act (RCRA). A major part of our ORNL program involves the development of separation technologies that are necessary for the complete treatment of mixed wastes. The residues from the MSO treatment of the mixed wastes must be processed further to separate the radioactive components, to concentrate and recycle residues, or to convert the residues into forms acceptable for final disposal. This paper is a review of the MSO requirements for separation technologies, the information now available, and the concepts for our development studies

    Pace, Brenda R. [Idaho National Lab. (INL), Idaho Falls, ID (United States); Williams, Julie B. [Idaho National Lab. (INL), Idaho Falls, ID (United States)

    2013-11-01

    The U. S. Department of Energy (DOE) has a need to test nuclear fuels under conditions that subject them to short bursts of intense, high-power radiation called ‘transient testing’ in order to gain important information necessary for licensing new nuclear fuels for use in U.S. nuclear power plants, for developing information to help improve current nuclear power plant performance and sustainability, for improving the affordability of new generation reactors, for developing recyclable nuclear fuels, and for developing fuels that inhibit any repurposing into nuclear weapons. To meet this mission need, DOE is considering alternatives for re-use and modification of existing nuclear reactor facilities to support a renewed transient testing program. One alternative under consideration involves restarting the Transient Reactor Test (TREAT) reactor located at the Materials and Fuels Complex (MFC) on the Idaho National Laboratory (INL) site in southeastern Idaho. This report summarizes cultural resource investigations conducted by the INL Cultural Resource Management Office in 2013 to support environmental review of activities associated with restarting the TREAT reactor at the INL. These investigations were completed in order to identify and assess the significance of cultural resources within areas of potential effect associated with the proposed action and determine if the TREAT alternative would affect significant cultural resources or historic properties that are eligible for nomination to the National Register of Historic Places. No archaeological resources were identified in the direct area of potential effects for the project, but four of the buildings proposed for modifications are evaluated as historic properties, potentially eligible for nomination to the National Register of Historic Places. This includes the TREAT reactor (building #), control building (building #), guardhouse (building #), and warehouse (building #). The proposed re-use of these historic

  16. International Trade Drives Global Resource Use: A Structural Decomposition Analysis of Raw Material Consumption from 1990-2010.

    Plank, Barbara; Eisenmenger, Nina; Schaffartzik, Anke; Wiedenhofer, Dominik

    2018-04-03

    Globalization led to an immense increase of international trade and the emergence of complex global value chains. At the same time, global resource use and pressures on the environment are increasing steadily. With these two processes in parallel, the question arises whether trade contributes positively to resource efficiency, or to the contrary is further driving resource use? In this article, the socioeconomic driving forces of increasing global raw material consumption (RMC) are investigated to assess the role of changing trade relations, extended supply chains and increasing consumption. We apply a structural decomposition analysis of changes in RMC from 1990 to 2010, utilizing the Eora multi-regional input-output (MRIO) model. We find that changes in international trade patterns significantly contributed to an increase of global RMC. Wealthy developed countries play a major role in driving global RMC growth through changes in their trade structures, as they shifted production processes increasingly to less material-efficient input suppliers. Even the dramatic increase in material consumption in the emerging economies has not diminished the role of industrialized countries as drivers of global RMC growth.

  17. Structural optimization procedure of a composite wind turbine blade for reducing both material cost and blade weight

    Hu, Weifei; Park, Dohyun; Choi, DongHoon

    2013-12-01

    A composite blade structure for a 2 MW horizontal axis wind turbine is optimally designed. Design requirements are simultaneously minimizing material cost and blade weight while satisfying the constraints on stress ratio, tip deflection, fatigue life and laminate layup requirements. The stress ratio and tip deflection under extreme gust loads and the fatigue life under a stochastic normal wind load are evaluated. A blade element wind load model is proposed to explain the wind pressure difference due to blade height change during rotor rotation. For fatigue life evaluation, the stress result of an implicit nonlinear dynamic analysis under a time-varying fluctuating wind is converted to the histograms of mean and amplitude of maximum stress ratio using the rainflow counting algorithm Miner's rule is employed to predict the fatigue life. After integrating and automating the whole analysis procedure an evolutionary algorithm is used to solve the discrete optimization problem.

    1999-01-01

    Proper decomposition of the sample is one of the basic requirements of the atomic absorption spectroscopic analysis. In the present studies, heavy metals (Cu, Fe, Mn and Zn) were determined in biological samples by designating them in a mixture of nitric acid and perchloric acid. The quantification was made with atomic absorption spectrometry using an air-acetylene flame. The reliability of the procedure used was checked by analysing standard reference materials from NBS and IAEA, such as Rice flour (NBS-SRM-1568), Horse Kidney (IAEA H-8), Mixed Human diet(IAEA H-9), Copepod (IAEA MA-A-1) and fish flesh (IAEA MA-A-2) under identical conditions. A good agreement was observed between determined and the certified values reported by NBS and IAEA. (author)

  20. Fluidized bed combustion bottom ash: A better and alternative geo-material resource for construction.

    Mandal, A K; Paramkusam, Bala Ramudu; Sinha, O P

    2018-04-01

    Though the majority of research on fly ash has proved its worth as a construction material, the utility of bottom ash is yet questionable due to its generation during the pulverized combustion process. The bottom ash produced during the fluidized bed combustion (FBC) process is attracting more attention due to the novelty of coal combustion technology. But, to establish its suitability as construction material, it is necessary to characterize it thoroughly with respect to the geotechnical as well as mineralogical points of view. For fulfilling these objectives, the present study mainly aims at characterizing the FBC bottom ash and its comparison with pulverized coal combustion (PCC) bottom ash, collected from the same origin of coal. Suitability of FBC bottom ash as a dike filter material in contrast to PCC bottom ash in replacing traditional filter material such as sand was also studied. The suitability criteria for utilization of both bottom ash and river sand as filter material on pond ash as a base material were evaluated, and both river sand and FBC bottom ash were found to be satisfactory. The study shows that FBC bottom ash is a better geo-material than PCC bottom ash, and it could be highly recommended as an alternative suitable filter material for constructing ash dikes in place of conventional sand.

  4. Resource sharing of online teaching materials: The lon-capa project

    Bauer, Wolfgang

    2004-03-01

    The use of information technology resources in conventional lecture-based courses, in distance-learning offerings, as well as hybrid courses, is increasing. But this may put additional burden on faculty, who are now asked to deliver this new content. Additionally, it may require the installation of commercial courseware systems, putting the colleges and universities in new financial licensing dependencies. To address exactly these two problems, the lon-capa system was invented to provide an open-source, gnu public license based, courseware system that allows for sharing of educational resources across institutional and disciplinary boundaries. This presentation will focus on both aspects of the system, the courseware capabilities that allow for customized environments for individual students, and the educational resources library that enables teachers to take full advantages of the work of their colleagues. Research results on learning effectiveness, resource and system usage patterns, and customization for different learning styles will be shown. Institutional perceptions of and responses to open source courseware systems will be discussed.

    Retrospective analysis. To compare perioperative costs and outcomes of patients undergoing single-level anterior cervical discectomy and fusions (ACDF) at both a service (orthopedic vs. neurosurgical) and individual surgeon level. Hospital systems are experiencing significant pressure to increase value of care by reducing costs while maintaining or improving patient-centered outcomes. Few studies have examined the cost-effectiveness cervical arthrodesis at a service level. A retrospective review of patients who underwent a primary 1-level ACDF by eight surgeons (four orthopedic and four neurosurgical) at a single academic institution between 2013 and 2015 was performed. Patients were identified by Diagnosis-Related Group and procedural codes. Patients with the ninth revision of the International Classification of Diseases coding for degenerative cervical pathology were included. Patients were excluded if they exhibited preoperative diagnoses or postoperative social work issues affecting their length of stay. Comparisons of preoperative demographics were performed using Student t tests and chi-squared analysis. Perioperative outcomes and costs for hospital services were compared using multivariate regression adjusted for preoperative characteristics. A total of 137 patients diagnosed with cervical degeneration underwent single-level ACDF; 44 and 93 were performed by orthopedic surgeons and neurosurgeons, respectively. There was no difference in patient demographics. ACDF procedures performed by orthopedic surgeons demonstrated shorter operative times (89.1 ± 25.5 vs. 96.0 ± 25.5 min; P = 0.002) and higher laboratory costs (Δ+$6.53 ± $5.52 USD; P = 0.041). There were significant differences in operative time (P = 0.014) and labor costs (P = 0.034) between individual surgeons. There was no difference in total costs between specialties or individual surgeons. Surgical subspecialty training does not significantly affect total costs of

  9. National Uranium Resource Evaluation. General procedure for calibration and reduction of aerial gamma-ray measurements: specification BFEC 1250-B

    Purvance, D.; Novak, E.

    1983-12-01

    The information contained in this specification was acquired over the course of the US Department of Energy (DOE) National Uranium Resource Evaluation (NURE) program during the period 1974 through 1982. NURE was a program of the DOE Grand Junction Area Office to acquire and compile geologic and other information with which to assess the magnitude and distribution of uranium resources and to determine areas favorable for the occurrence of uranium in the United States. Bendix Field Engineering Corporation (BFEC) has been the operating contractor for the DOE Grand Junction facility. The requirements stipulated herein had been incorporated as contractual specifications for the various subcontractors engaged in the aerial gamma-ray surveys, which were a major aspect of the NURE program. Although this phase of NURE activities has been completed, there exists valuable knowledge gained from these years of experience in the calibration of gamma-ray spectrometer systems and in the reduction of calibration data. Specification BFEC 1250-B is being open-filed by the US Department of Energy at this time to make this knowledge available to those desiring to apply gamma-ray spectrometry to other geophysical problems

  10. The influence of procedure delay on resource use: a national study of patients with open tibial fracture.

    Sears, Erika Davis; Burke, James F; Davis, Matthew M; Chung, Kevin C

    2013-03-01

    The purpose of this study was to (1) understand national variation in delay of emergency procedures in patients with open tibial fracture at the hospital level and (2) compare length of stay and cost in patients cared for at the best- and worst-performing hospitals for delay. The authors retrospectively analyzed the 2003 to 2009 Nationwide Inpatient Sample. Adult patients with open tibial fracture were included. Hospital probability of delay in performing emergency procedures beyond the day of admission was calculated. Multilevel linear regression random-effects models were created to evaluate the relationship between the treating hospital's tendency for delay (in quartiles) and the log-transformed outcomes of length of stay and cost. The final sample included 7029 patients from 332 hospitals. Patients treated at hospitals in the fourth (worst) quartile for delay were estimated to have 12 percent (95 percent CI, 2 to 21 percent) higher cost compared with patients treated at hospitals in the first quartile. In addition, patients treated at hospitals in the fourth quartile had an estimated 11 percent (95 percent CI, 4 to 17 percent) longer length of stay compared with patients treated at hospitals in the first quartile. Patients with open tibial fracture treated at hospitals with more timely initiation of surgical care had lower cost and shorter length of stay than patients treated at hospitals with less timely initiation of care. Policies directed toward mitigating variation in care may reduce unnecessary waste.

  13. Municipal wastes and landfield gases utilization - renewable resource of energy and materials

    Kuburovic, M.; Jovovic, A.

    2002-01-01

    Urbanization and industrialization, have been fundamental causes of environmental pollution (of water, air and land) which the cities were unable to handle. There is already enough evidence of the fact that the role of technology in environmental matters is moving in two important directions: sustainable development, dealing primary with global problems, and preventive technology, designed to reduce the environmental effects of processes, operations, and products. Treatment plants for industrial and municipal wastes, emission controls for incinerators, and safe landfills for waste disposal were developed to control air, water, and land pollution. Now, this 'end-of-pipe' treatment technologies are still the way of environmental protection philosophy, particularly in the developing countries. New environmental standards demand more and more rigorous preventive environmental protection technologies, therefore further development of industrial production requires the rational use of natural sources of raw materials and energy. Production and the use of goods with the minimum municipal and industrial wastes and the development of recycling technology provided closed cycle of materials. Main principles for the development and exploitation of the technology with the minimum or without waste materials and energy are: the use of renewable sources of material and energy, maximum use of waste materials and waste energy, waste minimisation and reduction of energy losses in the production, development of new industrial processes operating with minimum material and energy losses in products exploitation period and after that, and the responsible use of natural sources, products and energy in the field of industry and consumption.

    Full Text Available The purpose of the work is to establish some rational modes of receipt of the food fibers (FF from secondary resources of vegetable raw materials. Studying chemical properties of research objects has been carried out by standard methods in accordance with the GOST 26183–84, GOST 7636–85, GOST 25555.3–82, GOST 28561–90. Determination of reducing and not reducing sugars content has been performed by the cyanide method; determination of pectinaceous substances' content – by the calcium-pectate method. As an enzyme medicine the earlier not studied complex enzyme medicine of proteolytic and amilolytic action of Bacillus subtilis and Penicillium emersonii cultures has been tested. Studying heat stability of complex enzyme medicine has been carried out at varying of the hydrolysis temperature from 40 °C to 80 °C. The fractional composition of carbohydrates of secondary resources of aubergines, vegetable marrows and onions conversion has been researched. Content of FF (cellulose, gemitsellyuloza, pectin in waste from conversion of vegetable marrows constitutes 42 % of general content of carbohydrates, aubergines – 39,2 %, and onion – 30,4 %. Chemical and carbohydrate structures of secondary resources of vegetable raw materials allow consider them as FF source, and also shows feasibility of their conversion without fractionation by the form of secondary resources. The rational modes of hydrolysis of vegetable raw materials secondary resources' mix for removing the accompanying organic compounds have been determined.

  15. Raw Materials Synthesis from Heavy Metal Industry Effluents with Bioremediation and Phytomining: A Biomimetic Resource Management Approach

    Salmah B. Karman

    2015-01-01

    Full Text Available Heavy metal wastewater poses a threat to human life and causes significant environmental problems. Bioremediation provides a sustainable waste management technique that uses organisms to remove heavy metals from contaminated water through a variety of different processes. Biosorption involves the use of biomass, such as plant extracts and microorganisms (bacteria, fungi, algae, yeast, and represents a low-cost and environmentally friendly method of bioremediation and resource management. Biosorption-based biosynthesis is proposed as a means of removing heavy metals from wastewaters and soils as it aids the development of heavy metal nanoparticles that may have an application within the technology industry. Phytomining provides a further green method of managing the metal content of wastewater. These approaches represent a viable means of removing toxic chemicals from the effluent produced during the process of manufacturing, and the bioremediation process, furthermore, has the potential to save metal resources from depletion. Biomimetic resource management comprises bioremediation, biosorption, biosynthesis, phytomining, and further methods that provide innovative ways of interpreting waste and pollutants as raw materials for research and industry, inspired by materials, structures, and processes in living nature.

  16. Potentials for Improvement of Resource Efficiency in Printed Circuit Board Manufacturing: A Case Study Based on Material Flow Cost Accounting

    Yi-Xuan Wang

    2017-05-01

    Full Text Available The pursuit of sustainable resource use by manufacturing companies is driven by resource scarcity, environmental awareness, and cost savings potentials. To address these issues, Material Flow Cost Accounting (MFCA has been developed and applied as an effective environmental management tool. Within MFCA’s general allocation, the accounts of products and losses are overrated by weight or volume. However, such a method is incompatible with Printed Circuit Board (PCB manufacturing because of industry characteristics in which primary inputs and products are measured by area. Based on MFCA, this case study systematically established several linear cost calculation models along the production process for capturing the actual waste flows as well as performing cost-benefit analysis. The recognition of previously ignored losses offered the incentive to find appropriate indicators to conduct cost-benefit analysis on hotspots for losses. Loss identification and analysis indicated that machining and wiring are the necessities and priorities of process optimization for resource efficiency improvement measures. Therefore, this research could not only advance the achievement of a profitable and sustainable production while improving resource efficiency at the source but could also provide support for decision making in PCB manufacturing.

  17. A Practical and Robust Execution Time-Frame Procedure for the Multi-Mode Resource-Constrained Project Scheduling Problem with Minimal and Maximal Time Lags

    Angela Hsiang-Ling Chen

    2016-09-01

    Full Text Available Modeling and optimizing organizational processes, such as the one represented by the Resource-Constrained Project Scheduling Problem (RCPSP, improve outcomes. Based on assumptions and simplification, this model tackles the allocation of resources so that organizations can continue to generate profits and reinvest in future growth. Nonetheless, despite all of the research dedicated to solving the RCPSP and its multi-mode variations, there is no standardized procedure that can guide project management practitioners in their scheduling tasks. This is mainly because many of the proposed approaches are either based on unrealistic/oversimplified scenarios or they propose solution procedures not easily applicable or even feasible in real-life situations. In this study, we solve a more true-to-life and complex model, Multimode RCPSP with minimal and maximal time lags (MRCPSP/max. The complexity of the model solved is presented, and the practicality of the proposed approach is justified depending on only information that is available for every project regardless of its industrial context. The results confirm that it is possible to determine a robust makespan and to calculate an execution time-frame with gaps lower than 11% between their lower and upper bounds. In addition, in many instances, the solved lower bound obtained was equal to the best-known optimum.

  1. Selective classification and quantification model of C&D waste from material resources consumed in residential building construction.

    Mercader-Moyano, Pilar; Ramírez-de-Arellano-Agudo, Antonio

    2013-05-01

    The unfortunate economic situation involving Spain and the European Union is, among other factors, the result of intensive construction activity over recent years. The excessive consumption of natural resources, together with the impact caused by the uncontrolled dumping of untreated C&D waste in illegal landfills have caused environmental pollution and a deterioration of the landscape. The objective of this research was to generate a selective classification and quantification model of C&D waste based on the material resources consumed in the construction of residential buildings, either new or renovated, namely the Conventional Constructive Model (CCM). A practical example carried out on ten residential buildings in Seville, Spain, enabled the identification and quantification of the C&D waste generated in their construction and the origin of the waste, in terms of the building material from which it originated and its impact for every m(2) constructed. This model enables other researchers to establish comparisons between the various improvements proposed for the minimization of the environmental impact produced by building a CCM, new corrective measures to be proposed in future policies that regulate the production and management of C&D waste generated in construction from the design stage to the completion of the construction process, and the establishment of sustainable management for C&D waste and for the selection of materials for the construction on projected or renovated buildings.

  2. Protein Structure Initiative Material Repository: an open shared public resource of structural genomics plasmids for the biological community

    Cormier, Catherine Y.; Mohr, Stephanie E.; Zuo, Dongmei; Hu, Yanhui; Rolfs, Andreas; Kramer, Jason; Taycher, Elena; Kelley, Fontina; Fiacco, Michael; Turnbull, Greggory; LaBaer, Joshua

    2010-01-01

    The Protein Structure Initiative Material Repository (PSI-MR; http://psimr.asu.edu) provides centralized storage and distribution for the protein expression plasmids created by PSI researchers. These plasmids are a resource that allows the research community to dissect the biological function of proteins whose structures have been identified by the PSI. The plasmid annotation, which includes the full length sequence, vector information and associated publications, is stored in a freely available, searchable database called DNASU (http://dnasu.asu.edu). Each PSI plasmid is also linked to a variety of additional resources, which facilitates cross-referencing of a particular plasmid to protein annotations and experimental data. Plasmid samples can be requested directly through the website. We have also developed a novel strategy to avoid the most common concern encountered when distributing plasmids namely, the complexity of material transfer agreement (MTA) processing and the resulting delays this causes. The Expedited Process MTA, in which we created a network of institutions that agree to the terms of transfer in advance of a material request, eliminates these delays. Our hope is that by creating a repository of expression-ready plasmids and expediting the process for receiving these plasmids, we will help accelerate the accessibility and pace of scientific discovery.

  3. Ranking procedure based on mechanical, durability and thermal behavior of mortars with incorporation of phase change materials

    Cunha, S.

    2015-12-01

    Full Text Available Nowadays, considering the high variety of construction products, adequate material selection, based on their properties and function, becomes increasingly important. In this research, a ranking procedure developed by Czarnecki and Lukowski is applied in mortars with incorporation of phase change materials (PCM. The ranking procedure transforms experimental results of properties into one numerical value. The products can be classified according to their individual properties or even an optimized combination of different properties. The main purpose of this study was the ranking of mortars with incorporation of different contents of PCM based in different binders. Aerial lime, hydraulic lime, gypsum and cement were the binders studied. For each binder, three different mortars were developed. Reference mortars, mortars with incorporation of 40% of PCM and mortars with incorporation of 40% of PCM and 1% of fibers, were tested. Results show that the incorporation of PCM in mortars changes their global performance.Actualmente, existen varios productos de construcción, siendo importante una adecuada selección, con base en sus principales propiedades y funciones. En esta investigación se aplicó un procedimiento de clasificación desarrollado por Czarnecki y Lukowski, en morteros con incorporación de materiales de cambio de fase (PCM.

    2009-01-01

    Objectives. We examined associations between material resources and late-life declines in health. Methods. We used logistic regression to estimate the odds of declines in self-rated health and incident walking limitations associated with material disadvantages in a prospective panel representative of US adults aged 51 years and older (N = 15 441). Results. Disadvantages in health care (odds ratio [OR] = 1.39; 95% confidence interval [CI] = 1.23, 1.58), food (OR = 1.69; 95% CI = 1.29, 2.22), and housing (OR = 1.20; 95% CI = 1.07, 1.35) were independently associated with declines in self-rated health, whereas only health care (OR = 1.43; 95% CI = 1.29, 1.58) and food (OR = 1.64; 95% CI = 1.31, 2.05) disadvantage predicted incident walking limitations. Participants experiencing multiple material disadvantages were particularly susceptible to worsening health and functional decline. These effects were sustained after we controlled for numerous covariates, including baseline health status and comorbidities. The relations between health declines and non-Hispanic Black race/ethnicity, poverty, marital status, and education were attenuated or eliminated after we controlled for material disadvantage. Conclusions. Material disadvantages, which are highly policy relevant, appear related to health in ways not captured by education and poverty. Policies to improve health should address a range of basic human needs, rather than health care alone. PMID:19890175

    2017-09-01

    Full Text Available The research considers the issue of the provision of agrarian enterprises in Ukraine by material and technical resources and effective use of them. The scientific novelty of the results obtained is in the research of theoretical positions, substantiation of applied approaches concerning the organization of material and technical provision of enterprises of the agrarian sector, in particular, Mykolaiv region, taking into account the proposals of the second market of agricultural machinery, units, and aggregates. Methodology. The purpose of the article is the research and estimation of the current state of the provision of agrarian enterprises by material and technical resources. The object of scientific research is the process of provision of material and technical resources for enterprises of the agrarian sector in Mykolaiv region. The level of material and technical resources at agricultural enterprises in Mykolaiv region is analysed. Relative improvement of the situation with technical equipment and energy supply of agriculture in the Mykolaiv region since 2014 is defined; however, the dynamics are not active sufficiently and do not exceed five percent. The ratio between the amount of machinery purchased and disposed of by depreciation is disproportionate, the equipment provided by the unit of area, and the load on the machines available in the farms do not meet the requirements. The dynamics of capital and direct foreign investments in agriculture of Mykolaiv region, which during the research period increased, is investigated. It is proved that despite the rather successful development of capital investments by large-scale agricultural producers in the region, financial investments in modernization, repair, and acquisition of the new technology by small business entities are not sufficiently active. The authors substantiate that the tasks of technical re-equipment for commodity producers of the Mykolaiv region remain one of the most important

  8. Damage measurement of structural material by electron backscatter diffraction. Quantification of measurement quality toward standardization of measurement procedure

    Kamaya, Masayuki

    2011-01-01

    Several attempts have been made to assess the damage induced in materials by crystal orientation distributions identified using electron backscatter diffraction (EBSD). In particular, the local misorientation, which is the misorientation between neighboring measurement points, was shown to correlate well with the degree of material damage such as plastic strain, fatigue and creep. However, the damage assessments conducted using the local misorientations were qualitative rather than quantitative. The local misorientation can be correlated theoretically with physical parameters such as dislocation density. However, the error in crystal orientation measurements makes quantitative evaluation of the local misorientation difficult. Furthermore, the local misorientation depends on distance between the measurement points (step size). For a quantitative assessment of the local misorientation, the error in the crystal orientation measurements must be reduced or the degree of error must be shown quantitatively. In this study, first, the influence of the quality of measurements (accuracy of measurements) and step size on the local misorientation was investigated using stainless steel specimens damaged by tensile deformation or fatigue. By performing the crystal orientation measurements with different conditions, it was shown that the quality of measurement could be represented by the error index, which was previously proposed by the author. Secondly, a filtering process was applied in order to improve the accuracy of crystal orientation measurements and its effect was investigated using the error index. It was revealed that the local misorientations obtained under different measurement conditions could be compared quantitatively only when the error index and the step size were almost or exactly the same. It was also shown that the filtering process could successfully reduce the measurement error and step size dependency of the local misorientations. By applying the filtering

    Highlights: {yields} Blends of Rosin and beeswax are studied by DSC, XRD, and optical microscopy. {yields} The first phase diagram beeswax/rosin is established. {yields} Polymorphic transitions are identified and appear to be highly related to rosin content. - Abstract: Rosin and beeswax are two complex natural materials presenting numerous applications in paints, adhesives, varnishes or inks. Melted, they are particularly interesting for their adhesion properties. This paper establishes the first phase diagram beeswax/rosin blends. A systematic approach using X-ray diffraction (XRD), differential scanning calorimetry (DSC) and polarised optical microscopy (POM) has been performed in order to describe the crystallographic structure and the thermal properties of two materials, beeswax and rosin, and their blends. Indeed, melting, softening and crystallisation temperatures, polymorphic transitions but also crystalline index has been investigated. The resulting phase diagram reveals a complex behaviour in terms of phase transformation and time-dependent phenomenon mainly representative of the complex composition of beeswax.

    2001-01-01

    The National Educators' Workshop (NEW:Update) series of workshops has been in existence since 1986. These annual workshops focus on technical updates and laboratory experiments for materials science, engineering and technology, involving new and traditional content in the field. Scores of educators and industrial and national laboratory personnel have contributed many useful experiments and demonstrations which were then published as NASA Conference Proceedings. This "out poring of riches" creates an ever-expanding shelf of valuable teaching tools for college, university, community college and advanced high school instruction. Now, more than 400 experiments and demonstrations, representing the first thirteen years of NEW:Updates have been selected and published on a CD-ROM, through the collaboration of this national network of materials educators, engineers, and scientists. The CD-ROM examined in this document utilizes the popular Adobe Acrobat Reader format and operates on most popular computer platforms. This presentation provides an overview of the second edition of Experiments in Materials Science, Engineering and Technology (EMSET2) CD-ROM, ISBN 0-13-030534-0.

  12. Separation procedure for the determination of Ag, Cd, Hg and Zn in biological material by radiochemical neutron activation analysis

    Haas, H F; Krivan, V

    1986-05-01

    A simple separation procedure for the determination of Ag, Au, Cd, Hg and Zn in biological material by radiochemical neutron activation analysis was developed. It enables the separation of the indicator radionuclides sup(110m)Ag, /sup 198/Au, /sup 115/Cd, /sup 203/Hg and /sup 65/Zn in a group with yields >99% and is well suited for the separation of /sup 203/Hg from /sup 75/Se and /sup 65/Zn from /sup 46/Sc. The separation of these radionuclides is often necessary because of the occurrence of instrumental interferences in the instrumental neutron activation analysis. Simultaneously, the limits of detection for Ag, Au and Cd can significantly be improved. The method is based on the decomposition of the sample in the mixture of HNO/sub 3//HCl/H/sub 2/O/sub 2/ and on the separation of Ag, Au, Cd, Hg and Zn on Dowex 1X8 from a sample solution being 1.5 M with HCl. The applicability of this method is demonstrated by the analysis of lichens and several kinds of fungi. For the experimental conditions used, the limits of detection are of the order of magnitude of 10 ng/g.

    2004-01-01

    Discolored teeth can be treated with resin veneers, but their color changes when confronted with staining solutions. Polishing procedures can provide a remedy for highly stained composites, but they tend to remove some materials as well. However, bleaching procedures are an effective, nondestructive method for solving the problem. The aim of this study was to compare the color change of three veneer composites exposed to staining solutions and to evaluate the effectiveness of a 15% hydrogen peroxide bleaching agent and three polishing systems to remove the stain. Forty-five disks (12 x 2 mm) each of Clearfil ST (Kuraray Co. Ltd., Osaka, Japan), Esthet-X (Dentsply/Caulk, Milford DE, USA), and Filtek A110 (3M ESPE, St. Paul, MN, USA) were prepared. The specimens were polished with Sof-Lex (3M ESPE), Enhance (Dentsply/Caulk), or PoGo (Dentsply/Caulk). Five specimens for each material-polishing system combination were immersed in coffee (Nescafe Classic, Nestle SA, Vevey, Switzerland) or tea (Earl Grey, Lipton, Blackfriars-London, England) for 7 days. The remaining disks were stored in water. Color measurements were made with a spectrophotometer (X-Rite Seroice SP78, Loaner, Köln, Germany) at baseline; after 1, 3, 5, and 7 days; and after bleaching and repolishing. After 1 week, one side of the specimens was bleached with Illuminé-office (Dentsply De Trey GmbH, Konstanz, Germany) for 1 hour, and the other side was repolished for 30 seconds. All comparisons of color change for the polishing systems, times, and staining solutions were subjected to repeated measurements of analysis of variance. Paired t-test was used to examine whether significant color differences (deltaE*) occurred during immersion at the specified time intervals (p < or = .05). Filtek A110 was the least stained resin composite. Its color remained under a deltaE* value of 2 during the study. Clearfil ST exhibited the most color change after 1 week. All specimens polished with Enhance showed less

    2004-03-03

    Inductively coupled plasma atomic emission spectrometry (ICP-AES) is a powerful, sensitive analytical technique with numerous applications in chemical characterization including that of ancient pottery, mainly due to its multi-element character, and the relatively short time required for the analysis. A critical step in characterization studies of ancient pottery is the selection of a suitable decomposition procedure for the ceramic matrix. The current work presents the results of a comparative study of six decomposition procedures applied on a standard ceramic potsherd reference material, SARM 69. The investigated decomposition procedures included three microwave-assisted decomposition procedures, one wet decomposition (WD) procedure by conventional heating, one combined microwave-assisted and conventional heating WD procedure, and one fusion procedure. Chemical analysis was carried out by ICP-AES. Five major (Si, Al, Fe, Ca, Mg), three minor (Mn, Ba, Ti) and two trace (Cu, Co) elements were determined and compared with their certified values. Quantitation was performed at two different spectral lines for each element and multi-element matrix-matched calibration standards were used. The recovery values for the six decomposition procedures ranged between 75 and 110% with a few notable exceptions. Data were processed statistically in order to evaluate the investigated decomposition procedures in terms of recovery, accuracy and precision, and eventually select the most appropriate one for ancient pottery analysis.

  15. Restoring State Control Over Forest Resources Through Administrative Procedures: Evidence From a Community Forestry Programme in Central Java, Indonesia

    Ahmad Maryudi

    2012-01-01

    Full Text Available In recent years, community forestry has emerged as a means to reform power constellations with regard to forest governance. Through community forestry, the central state promised to devolve several forest rights to local communities and encouraged them to get involved in decision making processes and the implementation of forest activities. However, experience in some countries indicates that the implementation of community forestry programmes is rarely followed by genuine power devolution to local forest users. Instead, these programmes may even serve as a means to retain or restore the central state’s control over forests. Using a case study of a community forestry programme implemented in Java, Indonesia, by a state forest company, this paper argues that the implementation of community forestry is also driven by the state’s interests to regain control over the forests. Research in eight villages in Central Java province reveals that the community forestry programmes are carefully structured according to numerous administrative procedures and estab- lish a mode of control through a bureaucratic design. ----- In den letzten Jahren hat sich community forestry als Mittel zur Reform von Machtkonstellationen in Bezug auf die Verwaltung von Wäldern herausgebildet. Der Zentralstaat versprach durch community forestry bestimmte Waldrechte an lokale Communities abzugeben und ermutigte sie, sich an Entscheidungsprozessen und der Implementierung von Forstaktivitäten zu beteiligen. Erfahrungen in einigen Ländern zeigen jedoch, dass die Implementierung von community forestry-Programmen selten mit einem tatsächlichen Machttransfer an lokale ForstnutzerInnen einhergeht, sondern diese Programme sogar als Mittel zur Rückgewinnung von zentralstaatlicher Kontrolle über Wälder dienen können. Anhand eines Fallbeispiels eines community forestry-Programms, das in Java, Indonesien, von einem staatlichen Forstunternehmen implementiert wird, argumentiere ich

  16. Air pollution, cardiovascular endpoints and susceptibility by stress and material resources: a systematic review of the evidence.

    Fuller, Christina H; Feeser, Karla R; Sarnat, Jeremy A; O'Neill, Marie S

    2017-06-14

    Evidence shows that both the physical and social environments play a role in the development of cardiovascular disease. The purpose of this systematic review is two-fold: First, we summarize research from the past 12 years from the growing number of studies focused on effect modification of the relationships between air pollution and cardiovascular disease (CVD) outcomes by socioeconomic position (SEP) and; second, we identify research gaps throughout the published literature on this topic and opportunities for addressing these gaps in future study designs. We identified 30 articles that examined the modifying effects of either material resources or psychosocial stress (both related to SEP) on associations between short and long-term air pollution exposure and CVD endpoints. Although 18 articles identified at least one interaction between an air pollutant and material resource indicator, 11 others did not. Support for susceptibility to air pollution by psychosocial stress was weaker; however, only three articles tested this hypothesis. Further studies are warranted to investigate how air pollution and SEP together may influence CVD. We recommend that such research include thorough assessment of air pollution and SEP correlations, including spatial correlation; investigate air pollution indices or multi-pollutant models; use standardized metrics of SEP to enhance comparability across studies; and evaluate potentially susceptible populations.

  17. Linking material flow analysis and resource policy via future scenarios of in-use stock: an example for copper.

    Gerst, Michael D

    2009-08-15

    A key aspect to achieving long-term resource sustainability is the development of methodologies that explore future material cycles and their environmental impact. Using a novel dynamic in-use stock model and scenario analysis, I analyzed the multilevel global copper cycle over the next 100 years. In 1990, the industrialized world had an in-use copper stock about twice as large as the developing world and a per capita in-use stock of about six times as large. By 2100, the developing world will have an in-use copper stock about three times as large as the industrialized world, but the industrialized world will maintain a per capita stock twice that of the developing world. Under a scenario of no material substitution or technological change in copper products, global in-use stock in 2100 will be about as large as currently known copper resources. However, current scrap recycling trends and exploration will alleviate absolute supply pressure but not environmental impacts from decreasing copper are grades. Additionally, unexpected emergent properties of dematerialization are observed from the in-use stock model that arise solely from the properties of stock dynamics, an infrequently discussed cause of dematerialization in the literature.

  18. Water Resources Research Program. Abatement of malodors at diked, dredged-material disposal sites. Final report

    Harrison, W.; Dravnieks, A.; Zussman, R.; Goltz, R.

    1976-06-01

    Samples of malodorous air and dredged material were collected at diked disposal sites at the following locations: Buffalo, NY; Milwaukee, WI; Mobile, AL; York Harbor, ME; Houston, TX; Detroit, MI; and Anacortes, WA; during the period July--October, 1975. Odorous compounds in the air samples were identified by gas chromatography/mass spectrometry, while the detection threshold, intensity, and character of the various odors were determined by experienced panelists using a dynamic, forced-choice-triangle olfactometer. Although significant problems with malodors were not observed beyond the disposal-area dikes during site visits, noteworthy odor episodes had occurred at some sites. An odor-abatement strategy is presented for handling the expected range of odor conditions at dredged-material disposal sites. Its aim is to reduce to an acceptable level the intensity of malodors in an affected community. The main steps in the strategy cover selection of the disposal site, site preparation, odor characterization of sediments to be dredged, malodor abatement during dredging and disposal operations, malodor abatement after filling of the disposal site, and the handling of malodor complaints.

  20. Sustainable prevention of resource conflicts. Conflict risks for access and use of raw materials (report 1); Rohstoffkonflikte nachhaltig vermeiden. Konfliktrisiken bei Zugang und Nutzung von Rohstoffen (Teilbericht 1)

    Taenzler, Dennis; Westerkamp, Meike [Adelphi Research, Berlin (Germany); Supersberger, Nikolaus; Ritthoff, Michael; Bleischwitz, Raimund [Wuppertal Institut fuer Klima, Umwelt, Energie GmbH, Wuppertal (Germany)

    2011-04-15

    Inequalities of resources ownership and the consequences of the exploitation of non-renewable resources have always caused violent conflicts of varying intensity. The resulting interdependence between conflicts on the one hand and resources on the other hand - discussed here under the term of conflict-resources nexus - is complex and requires a detailed theoretical and conceptional assessment. The risks of conflict vary as a function of the constellations of actors and the existing political, economic and social boundary conditions. These risks are often globally linked and reflect the flow of resources between consumer countries, transit countries, and producer countries. Conflicts in producer countries may endanger the supply of raw materials to consumer countries. Whether the raw material is an energetic resource like natural gas, petroleum, or coal, or a non-energetic resource like coltane or copper: There are many who demand that Germany should adapt to stronger competition and shorter supply and should also be aware of the possibility of conflicts about raw materials. This part-report of the project 'Sustainable Prevention of Resource Conflicts' presents important theoretical and conceptional considerations on the risk of conflict in the raw materials sector. On this basis, further reports will present case studies, scenarios, and preventive strategies. (orig./RHM)

  3. A procedure to improve the information flow in the assessment of discoveries of oil and gas resources in the Brazilian context

    Rosa, Henrique; Suslick, Saul B.; Sousa, Sergio H.G. de [Universidade Estadual de Campinas, SP (Brazil). Inst. of Geosciences; Castro, Jonas Q. [ANP - Brazilian National Petroleum Agency, Rio de Janeiro, RJ (Brazil)

    2004-07-01

    This paper is focused on the elaboration of a standardization model for the existing flow of information between the Petroleum National Agency (ANP) and the concessionaire companies in the event of the discovery of any potentially commercial hydrocarbon resources inside their concession areas. The method proposed by Rosa (2003) included the analysis of a small sample of Oil and Gas Discovery Assessment Plans (PADs), elaborated by companies that operate in exploratory blocks in Brazil, under the regulatory context introduced by the Petroleum Law (Law 9478, August, 6th, 1997). The analysis of these documents made it possible to identify and target the problems originated from the lack of standardization. The results obtained facilitated the development of a model that helps the creation process of Oil and Gas Discovery Assessment Plans. It turns out that the standardization procedures suggested provide considerable advantages while speeding up several technical and regulatory steps. A software called 'ePADs' was developed to consolidate the automation of the several steps in the model for the standardization of the Oil and Gas Discovery Assessment Plans. A preliminary version has been tested with several different types of discoveries indicating a good performance by complying with all regulatory aspects and operational requirements. (author)

  4. A definition and evaluation procedure of generalized stress intensity factors at cracks and multi-material wedges

    Song Chongmin

    2010-01-01

    A definition of generalized stress intensity factors is proposed. It is based on a matrix function solution for singular stress fields obtained from the scaled boundary finite-element method. The dimensions of the matrix are equal to the number of singular terms. Not only real and complex power singularities but also power-logarithmic singularities are represented in a unified expression without explicitly determining the type of singularity. The generalized stress intensity factors are evaluated directly from the definition by following standard stress recovery procedures in the finite element method. Numerical examples are presented to valid the definition and evaluation procedure.

    Glycated albumin is an intermediate glycaemic control marker for which there are several measurement procedures with entirely different reference intervals. We have developed a reference measurement procedure for the purpose of standardizing glycated albumin measurements. The isotope dilution liquid chromatography/tandem mass spectrometry method was developed as a reference measurement procedure for glycated albumin. The stable isotopes of lysine and fructosyl-lysine, which serve as an internal standard, were added to albumin isolated from serum, followed by hydrogenation. After hydrolysis of albumin with hot hydrochloric acid, the liberated lysine and fructosyl-lysine were measured by liquid chromatography/tandem mass spectrometry, and their concentrations were determined from each isotope ratio. The reference materials (JCCRM611) for determining of glycated albumin were prepared from pooled patient blood samples. The isotope dilution-tandem mass spectrometry calibration curve of fructosyl-lysine and lysine showed good linearity (r = 0.999). The inter-assay and intra-assay coefficient of variation values of glycated albumin measurement were 1.2 and 1.4%, respectively. The glycated albumin values of serum in patients with diabetes assessed through the use of this method showed a good relationship with routine measurement procedures (r = 0.997). The relationship of glycated albumin values of the reference material (JCCRM611) between these two methods was the same as the relationship with the patient serum samples. The Committee on Diabetes Mellitus Indices of the Japan Society of Clinical Chemistry recommends the isotope dilution liquid chromatography/tandem mass spectrometry method as a reference measurement procedure, and JCCRM611 as a certified reference material for glycated albumin measurement. In addition, we recommend the traceability system for glycated albumin measurement. © The Author(s) 2015.

    In order to choose an appropriate cell-wall material (CWM) isolation procedure in grapes cv. Monastrell, four different standard procedures have been tested, and a comparison made of the amount of cell-wall material obtained, its composition and morphology. The CWM was isolated as the 70% ethanol insoluble residue (de Vries method), as the absolute ethanol insoluble residue filtered sequentially through nylon mesh (Nunan method), as the insoluble residue in sodium deoxycholate-phenol-acetic acid-water (Selvendran method) and as the N-[2-hydroxyethyl]-piperazine-N'-2-ethanesulfonic acid (HEPES) insoluble residue (Vidal method). All extractions were done in triplicate and the efficiency of the extractive procedure established. Carbohydrates, proteins, and phenolic compounds were analysed, as the main constituents of CWM. The morphology of the isolated CWM was visualized by scanning electron microscopy (SEM). The Selvendran method had the highest efficiency, while the Nunan method had the lower one. Regarding the carbohydrates composition, the four different CWM were rich in uronic acids and glucose, together with varying amounts of arabinose, xylose, mannose and galactose. The Selvendran method had the lower value of total carbohydrates and the CWM shows more plasmatic membrane impurities in SEM images. The chemical results of the Vidal and de Vries methods were quite similar, but the Vidal method was more time consuming than the de Vries method. According to the results, the de Vries method was chosen to produce a representative cell-wall material fraction from Monastrell grapes skin.

    Highlights: • WtE plants are to be optimized beyond current acceptance levels. • Emission and consumption data before and after 5 technical improvements are discussed. • Plant performance can be increased without introduction of new techniques or re-design. • Diagnostic skills and a thorough understanding of processes and operation are essential. - Abstract: Due to ongoing developments in the EU waste policy, Waste-to-Energy (WtE) plants are to be optimized beyond current acceptance levels. In this paper, a non-exhaustive overview of advanced technical improvements is presented and illustrated with facts and figures from state-of-the-art combustion plants for municipal solid waste (MSW). Some of the data included originate from regular WtE plant operation – before and after optimisation – as well as from defined plant-scale research. Aspects of energy efficiency and (re-)use of chemicals, resources and materials are discussed and support, in light of best available techniques (BAT), the idea that WtE plant performance still can be improved significantly, without direct need for expensive techniques, tools or re-design. In first instance, diagnostic skills and a thorough understanding of processes and operations allow for reclaiming the silent optimisation potential

  12. Evaluation procedure for Service Level C and D upper shelf toughness criteria for Linde 80 weld material

    Gamble, R.M.

    1993-09-01

    Procedures have been defined to evaluate the upper shelf toughness criteria recently defined by ASME Section XI Subgroup on Evaluation Standards for ASME Service Level C and D conditions. These procedures and the ASME criteria were applied to assess the upper toughness requirements for axial Linde 80 welds in a typical PWR reactor pressure vessel beltline geometry. Because there is a wide spectrum of possible Level C and D events, the evaluation was performed for a bounding thermal transient and results were obtained to determine allowable pressure versus upper shelf energy. The allowable pressure for the bounding thermal transient was found to be above normal operating pressure for upper shelf energies equal to and greater than 40 ft-lb. Because a bounding thermal transient was used, the allowable pressures determined in this work should be minimum values. The results from this work provide a screening criterion to quickly identify limiting transients that may require more detailed analysis and an analysis procedure to assess compliance with ASME upper shelf energy criteria for Service Level C and D events. For events with significant thermal transients, such as those evaluated in this work, the transient pressure typically decreases rapidly from normal operating pressure to 1,500 psi or less before the maximum thermal K I , is reached. Comparing this pressure range with the allowable pressure versus upper shelf energy curves determined in this work indicates that the transient pressures are significantly less than the allowables computed for Level C and D events; consequently, Level A/B conditions will likely dictate the upper shelf requirements for most applications

    Schuler, W A; Bader, F; Rink, K H; Weigert, W

    1966-12-03

    A procedure is described for soil stabilization and/or sand consolidation. The method entails the injection of a synthetic resin gel (such as the polymer of acrolein) into the soil or sand and allowing it to harden. The hardened gel closes the permeability of the sand or soil to the entry or passage of water or other fluids. The method may be used for such purposes as preparing structural foundations, plugging water-producing formations in oil wells, or in any case where exclusion of water is desirable.

  14. SEM-EDX Study of the Degradation Process of Two Xenograft Materials Used in Sinus Lift Procedures

    2017-05-01

    Full Text Available Some studies have demonstrated that in vivo degradation processes are influenced by the material’s physico-chemical properties. The present study compares two hydroxyapatites manufactured on an industrial scale, deproteinized at low and high temperatures, and how physico-chemical properties can influence the mineral degradation process of material performance in bone biopsies retrieved six months after maxillary sinus augmentation. Residual biomaterial particles were examined by field scanning electron microscopy (SEM and energy dispersive X-ray spectroscopy (EDX to determine the composition and degree of degradation of the bone graft substitute material. According to the EDX analysis, the Ca/P ratio significantly lowered in the residual biomaterial (1.08 ± 0.32 compared to the initial composition (2.22 ± 0.08 for the low-temperature sintered group, which also presented high porosity, low crystallinity, low density, a large surface area, poor stability, and a high resorption rate compared to the high-temperature sintered material. This demonstrates that variations in the physico-chemical properties of bone substitute material clearly influence the degradation process. Further studies are needed to determine whether the resorption of deproteinized bone particles proceeds slowly enough to allow sufficient time for bone maturation to occur.

  18. Abatement of styrene waste gas emission by biofilter and biotrickling filter: comparison of packing materials and inoculation procedures.

    Pérez, M C; Álvarez-Hornos, F J; Portune, K; Gabaldón, C

    2015-01-01

    The removal of styrene was studied using two biofilters packed with peat and coconut fibre (BF1-P and BF2-C, respectively) and one biotrickling filter (BTF) packed with plastic rings. Two inoculation procedures were applied: an enriched culture with strain Pseudomonas putida CECT 324 for BFs and activated sludge from a municipal wastewater treatment plant for the BTF. Inlet loads (ILs) between 10 and 45 g m(-3) h(-1) and empty bed residence times (EBRTs) from 30 to 120 s were applied. At inlet concentrations ranging between 200 and 400 mg Nm(-3), removal efficiencies between 70 % and 95 % were obtained in the three bioreactors. Maximum elimination capacities (ECs) of 81 and 39 g m(-3) h(-1) were obtained for the BF1-P and BF2-C, respectively (IL of 173 g m(-3) h(-1) and EBRT of 60 s in BF1-P; IL of 89 g m(-3) h(-1) and EBRT of 90 s in BF2-C). A maximum EC of 52 g m(-3) h(-1) was obtained for the BTF (IL of 116 g m(-3) h(-1), EBRT of 45 s). Problems regarding high pressure drop appeared in the peat BF, whereas drying episodes occurred in the coconut fibre BF. DGGE revealed that the pure culture used for BF inoculation was not detected by day 105. Although two different inoculation procedures were applied, similar styrene removal at the end of the experiments was observed. The use as inoculum of activated sludge from municipal wastewater treatment plant appears a more feasible option.

    Three very accurate (definitive) methods by RNAA for the determination of Se, As and Fe respectively, which were recently elaborated in our laboratory, are reviewed and their use in certification of reference materials and in checking the assigned values in proficiency tests is demonstrated on several examples. According to VIM 3 nomenclature these methods may be called: ratio primary reference measurement procedures (RPRMPs). RPRMPs with their expanded uncertainties of 2.7-3.6 % are comparable to ID-MS methods and are the only methods of such high metrological quality which can be used for the determination of trace amounts of monoisotopic elements.

    2018-01-01

    Mesothelial/monocytic incidental cardiac excrescences (MICE) are unusual findings during the histological analysis of material from the pericardium, mediastinum, or other tissues collected in open-heart surgery. Despite their somewhat worrisome histological appearance, they show a benign clinical course, and further treatment is virtually never necessary. Hence, the importance of recognizing the entity relays in its differential diagnosis, as an unaware medical pathologist may misinterpret it for a malignant neoplasm. Other mesothelial and histiocytic proliferative lesions, sharing very close histological morphology and immunohistochemistry features with MICE, have been described in sites other than the heart or the mediastinum. This similarity has led to the proposal of the common denomination "histiocytosis with raisinoid nuclei." We report three cases from the pathology archives of the Heart Institute of São Paulo University (Incor/HC-FMUSP), diagnosed as "mesothelial/monocytic incidental cardiac excrescence," with immunohistochemical documentation, and provide a literature review of this entity.

    2014-07-01

    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.

  5. Procedure for the creation of reproducible acoustic coupling using the ultrasonic contact method for nondestructive testing of materials

    Tomilov, B.V.

    1979-01-01

    The transducer is pressed to the specimen, a lubricating coating being applied as an intermediate layer. By means of a vibrator belonging to the transducer there are generated vibrations, the growth rate of the amplitude of the reflected signal picked up being observed. This growth rate is monotonously decreasing. If the growth rate is abruptly decreasing or if the amplitude of the measured signal remains constant the vibrator is turned off, because now good acoustic contact is established. After a short time of waiting for the residual stress of the transducer to decay, recording of the ultrasonic parameters may then be taken up. The method can be applied to thickness measurements and inhomogeneous materials with low surface quality. (RW) [de

    To assess tooth crown's color after intracanal treatment with triple antibiotic paste (TAP) or calcium hydroxide (CH); cervical sealing with glass ionomer cement (GIC) or mineral trioxide aggregate (MTA); and bleaching with carbamide peroxide. After pulp removal and color spectrophotometer measurement, 50 bovine incisors were divided into 4 experimental groups and one control (untreated). Experiments were performed in phases (Ph). Ph1: TAP (ciprofloxacin, metronidazole, minocycline), TAPM (ciprofloxacin, metronidazole, amoxicillin), DAP (ciprofloxacin, metronidazole), or CH treatment groups. After 1 and 3 days (d); 1, 2, 3 weeks (w); and 1, 2, 3 and 4 months (m), color was measured and medications were removed. Ph2: GIC or MTA cervical sealing, each using half of the specimens from each group. Color was assessed after 1d, 3d; 1w, 2w, 3w; 1m and 2m. Ph3: Two bleaching sessions, each followed by color measurement. Data were analyzed with ANOVA and post-hoc Holm-Sidak method. Ph1: Specimens of TAP group presented higher color alteration (ΔE) mean than those of TAPM group. No significant difference was found among TAP or TAPM and CH, DAP or Control groups. Ph2: cervical sealing materials showed no influence on color alteration. Ph3: Different ΔE means (from different groups), prior to bleaching, became equivalent after one bleaching session. TAP induces higher color alteration than TAPM; color alteration increases over time; cervical sealing material has no influence on color alteration; and, dental bleaching was able to recover, at least partially, the tooth crown's color.

    Two large size Glass Composite Material (GCM) waste forms containing AgI-MOR were fabricated. One contained methyl iodide-loaded AgI-MOR that was received from Idaho National Laboratory (INL, Test 5, Beds 1 – 3) and the other contained iodine vapor loaded AgIMOR that was received from Oak Ridge National Laboratory (ORNL, SHB 2/9/15 ). The composition for each GCM was 20 wt% AgI-MOR and 80 wt% Ferro EG2922 low sintering temperature glass along with enough added silver flake to prevent any I2 loss during the firing process. The silver flake amounts were 1.2 wt% for the GCM with the INL AgI-MOR and 3 wt% for the GCM contained the ORNL AgI-MOR. The GCMs, nominally 100 g, were first uniaxially pressed to 6.35 cm (2.5 inch) diameter disks then cold isostatically pressed, before firing in air to 550°C for 1hr. They were cooled slowly (1°C/min) from the firing temperature to avoid any cracking due to temperature gradients. The final GCMs were ~5 cm in diameter (~2 inches) and non-porous with densities of ~4.2 g/cm³. X-ray diffraction indicated that they consisted of the amorphous glass phase with small amounts of mordenite and AgI. Furthermore, the presence of the AgI was confirmed by X-ray fluorescence. Methodology for the scaled up production of GCMs to 6 inch diameter or larger is also presented.

    2013-01-01

    A rapid method of sample decomposition and dissolution for bromoform heavies is described for the determination of REEs and thorium by inductively coupled plasma- optical emission spectrometry. For application to geochemical exploration to achieve the high sample throughput; a simple and rapid analytical procedure is a prerequisite. In order to speed-up the existing methodology, phosphate fusion was introduced for decomposition of samples. In the proposed method, bromoform-heavies material are fused with 1:1 mixture of sodium dihydrogen orthophosphate and tetra-sodium pyrophosphate and dissolved in distilled water. After disintegration of melt, the solution was subjected to oxalate precipitation followed by R 2 O 3 separation for separating the REEs from major matrix interfering elements. The rare earth elements and thorium in the resultant solution were determined by ICP-OES. The results are compared with the results obtained by well-established existing dissolution procedures involving HF-HCl-HClO 4 acid treatment and NaF/KHF 2 fusion followed by H 2 SO 4 acid fuming. The accuracy of the method was evaluated by doping the phosphate blank with known amount of REEs and comparing the recoveries obtained using the present method. The method is simple, rapid and is suitable for the routine determination of REEs and Th in bromoform-heavies. The RSD of the method was found to be within 1-3% for Th and REEs by ICP-AES. (author)

  13. Effects of different etching methods and bonding procedures on shear bond strength of orthodontic metal brackets applied to different CAD/CAM ceramic materials.

    2018-03-01

    To investigate the shear bond strength (SBS) of orthodontic metal brackets applied to different types of ceramic surfaces treated with different etching procedures and bonding agents. Monolithic CAD/CAM ceramic specimens (N = 120; n = 40 each group) of feldspathic ceramic Vita Mark II, resin nanoceramic Lava Ultimate, and hybrid ceramic Vita Enamic were fabricated (14 × 12 × 3 mm). Ceramic specimens were separated into four subgroups (n = 10) according to type of surface treatment and bonding onto the ceramic surface. Within each group, four subgroups were prepared by phosphoric acid, hydrofluoric acid, Transbond XT primer, and Clearfill Ceramic primer. Mandibular central incisor metal brackets were bonded with light-cure composite. The SBS data were analyzed using three-way analysis of variance (ANOVA) and Tukey HSD tests. The highest SBS was found in the Vita Enamic group, which is a hybrid ceramic, etched with hydrofluoric acid and applied Transbond XT Adhesive primer (7.28 ± 2.49 MPa). The lowest SBS was found in the Lava Ultimate group, which is a resin nano-ceramic etched with hydrofluoric acid and applied Clearfill ceramic primer (2.20 ± 1.21 MPa). CAD/CAM material types and bonding procedures affected bond strength ( P .05). The use of Transbond XT as a primer bonding agent resulted in higher SBS.

  14. LC-MS/MS analytical procedure to quantify tris(nonylphenyl)phosphite, as a source of the endocrine disruptors 4-nonylphenols, in food packaging materials.

    Mottier, Pascal; Frank, Nancy; Dubois, Mathieu; Tarres, Adrienne; Bessaire, Thomas; Romero, Roman; Delatour, Thierry

    2014-01-01

    Tris(nonylphenyl)phosphite, an antioxidant used in polyethylene resins for food applications, is problematic since it is a source of the endocrine-disrupting chemicals 4-nonylphenols (4NP) upon migration into packaged foods. As a response to concerns surrounding the presence of 4NP-based compounds in packaging materials, some resin producers and additive suppliers have decided to eliminate TNPP from formulations. This paper describes an analytical procedure to verify the "TNPP-free" statement in multilayer laminates used for bag-in-box packaging. The method involves extraction of TNPP from laminates with organic solvents followed by detection/quantification by LC-MS/MS using the atmospheric pressure chemical ionisation (APCI) mode. A further acidic treatment of the latter extract allows the release of 4NP from potentially extracted TNPP. 4NP is then analysed by LC-MS/MS using electrospray ionisation (ESI) mode. This two-step analytical procedure ensures not only TNPP quantification in laminates, but also allows the flagging of other possible sources of 4NP in such packaging materials, typically as non-intentionally added substances (NIAS). The limits of quantification were 0.50 and 0.48 µg dm⁻² for TNPP and 4NP in laminates, respectively, with recoveries ranging between 87% and 114%. Usage of such analytical methodologies in quality control operations has pointed to a lack of traceability at the packaging supplier level and cross-contamination of extrusion equipment at the converter level, when TNPP-containing laminates are processed on the same machine beforehand.

    2015-01-01

    To select a Kjeldahl procedure suitable for the determination of total protein in reference materials used in laboratory medicine, we reviewed in our previous article Kjeldahl methods adopted by clinical chemistry and found an indirect two-step analysis by total Kjeldahl nitrogen corrected for its nonprotein nitrogen and a direct analysis made on isolated protein precipitates. In this article, we compare both procedures on various reference materials. An indirect Kjeldahl method gave falsely lower results than a direct analysis. Preliminary performance parameters qualify the direct Kjeldahl analysis as a suitable primary reference procedure for the certification of total protein in reference laboratories.

  17. Preparation of biological samples for transmission X-ray microanalysis: a review of alternative procedures to the use of sectioned material

    Sigee, D.C.

    1988-01-01

    Although transmission X-ray microanalysis of biological material has traditionally been carried out mainly on sectioned preparations, a number of alternative procedures exist. These are considered under three major headings - whole cell preparations, analysis of cell homogenates and biological fluids, and applications of the technique to microsamples of purified biochemicals. These three aspects provide a continuous range of investigative level - from the cellular to the molecular. The use of X-ray microanalysis with whole cell preparations is considered in reference to eukaryote (animal) cells and prokaryotes - where it has particular potential in environmental studies on bacteria. In the case of cell homogenates and biological fluids, the technique has been used mainly with microdroplets of animal material. The use of X-ray microanalysis with purified biochemicals is considered in relation to both particulate and non-particulate samples. In the latter category, the application of this technique for analysis of thin films of metalloprotein is particularly emphasised. It is concluded that wider use could be made of the range of preparative techniques available - both within a particular investigation, and in diverse fields of study. Transmission X-ray microanalysis has implications for environmental, physiological and molecular biology as well as cell biology

    Germany is dependent on imports for its metalliferous natural resources. Although prices have been declining significantly in recent months, numerous raw materials such as platinum, cobalt and rare earth elements continue to be exposed to price and supply risks. To ensure that German industry can respond better to this situation in their procurement activities, the German Mineral Resources Agency (DERA) at BGR has developed a raw material monitoring system on behalf of the German government. DERA experts have con figured a screening method for the early identification of possible procurement risks. This is the platform which enables German companies to gain the specific advice they require. All of the most important information on this issue is bundled within DERA 's internet portal (www.deutsche-rohstoffagentur.de). BGR also provides its expertise in other important fields with great societal relevance. BGR has been advising the national commission on ''Storage of High-level Radioactive Waste'' since 2014. Due to their comprehensive research activities in the field of radioactive waste disposal, BGR scientists are important technical experts to which the commission can turn to for geological information and advice.

  20. Fusion Bead Procedure for Nuclear Forensics Employing Synthetic Enstatite to Dissolve Uraniferous and Other Challenging Materials Prior to Laser Ablation Inductively Coupled Plasma Mass Spectrometry.

    Reading, David G; Croudace, Ian W; Warwick, Phillip E

    2017-06-06

    There is an increasing demand for rapid and effective analytical tools to support nuclear forensic investigations of seized or suspect materials. Some methods are simply adapted from other scientific disciplines and can effectively be used to rapidly prepare complex materials for subsequent analysis. A novel sample fusion method is developed, tested, and validated to produce homogeneous, flux-free glass beads of geochemical reference materials (GRMs), uranium ores, and uranium ore concentrates (UOC) prior to the analysis of 14 rare earth elements (REE) via laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The novelty of the procedure is the production of glass beads using 9 parts high purity synthetic enstatite (MgSiO 3 ) as the glass former with 1 part of sample (sample mass ∼1.5 mg). The beads are rapidly prepared (∼10 min overall time) by fusing the blended mixture on an iridium strip resistance heater in an argon-purged chamber. Many elements can be measured in the glass bead, but the rare earth group in particular is a valuable series in nuclear forensic studies and is well-determined using LA-ICP-MS. The REE data obtained from the GRMs, presented as chondrite normalized patterns, are in very good agreement with consensus patterns. The UOCs have comparable patterns to solution ICP-MS methods and published data. The attractions of the current development are its conservation of sample, speed of preparation, and suitability for microbeam analysis, all of which are favorable for nuclear forensics practitioners and geochemists requiring REE patterns from scarce or valuable samples.

  1. Renewable Resources and a Recycled Polymer as Raw Materials: Mats from Electrospinning of Lignocellulosic Biomass and PET Solutions

    Rachel Passos de Oliveira Santos

    2018-05-01

    Full Text Available Interest in the use of renewable raw materials in the preparation of materials has been growing uninterruptedly in recent decades. The aim of this strategy is to offer alternatives to the use of fossil fuel-based raw materials and to meet the demand for materials that are less detrimental to the environment after disposal. In this context, several studies have been carried out on the use of lignocellulosic biomass and its main components (cellulose, hemicelluloses, and lignin as raw materials for polymeric materials. Lignocellulosic fibers have a high content of cellulose, but there has been a notable lack of investigations on application of the electrospinning technique for solutions prepared from raw lignocellulosic biomass, even though the presence of cellulose favors the alignment of the fiber chains during electrospinning. In this investigation, ultrathin (submicrometric and nanoscale aligned fibers were successfully prepared via electrospinning (room temperature of solutions prepared with different contents of lignocellulosic sisal fibers combined with recycled poly(ethylene terephthalate (PET using trifluoroacetic acid (TFA as solvent. The “macro” fibers were deconstructed by the action of TFA, resulting in solutions containing their constituents, i.e., cellulose, hemicelluloses, and lignin, in addition to PET. The “macro” sisal fibers were reconstructed at the nanometer and submicrometric scale from these solutions. The SEM micrographs of the mats containing the components of sisal showed distinct fiber networks, likely due to differences in the solubility of these components in TFA and in their dielectric constants. The mechanical properties of the mats (dynamic mechanical analysis, DMA, and tensile properties were evaluated with the samples positioned both in the direction (dir of and in opposition (op to the alignment of the nano and ultrathin fibers, which can be considered a novelty in the analysis of this type of material

  4. Interactions of water with energy and materials in urban areas and agriculture. IWRM. Integrated water resources management. Conference proceedings

    Steusloff, Hartwig (ed.)

    2012-07-01

    The current rationale, range and significance of Integrated Water Resources Management (IWRM) are subject to increasing dimensionality, such as systemic conflicts between water users, increasing regulatory influences, and the growing energy requirements for providing the appropriate water resources. The competition between urban and agricultural consumers for water is dealt with as are regulatory, technological and socio-economic aspects of IWRM. The conference proceedings of IWRM Karlsruhe 2012 impart knowledge and relate practical experience in three key areas of IWRM: 1. Challenges for Future Cities and Efficient Agricultural Production Satisfying the growing demand for fresh water for a growing population as well as for agriculture bears the risk of aggravating the conflict between economic and ecological needs. Providing a reliable and secure supply of water for our future cities requires appropriate technical infrastructure systems coupled with environmentally optimized management. In this context it is essential to have greater awareness of the relationship of water and energy and of the overall water usage including the re-use of water 2. Competing Water Uses Water must be shared between domestic/municipal, industrial, agricultural, and hydropower users as well as between regions. This competition is intensified by the vulnerability of supply and sanitation systems to increasing climate extremes and to terrorism. 3. Regulatory and Policy Framework Using water is associated with a great number of externalities. For this reason a proper legislative and regulatory framework is prerequisite for proper management of the water supply, sewerage and storm-water services as well as water usage, all of which are essential for public health, economic development and environmental protection.

  5. ASTM F739 method for testing the permeation resistance of protective clothing materials: critical analysis with proposed changes in procedure and test-cell design.

    Anna, D H; Zellers, E T; Sulewski, R

    1998-08-01

    ASTM (American Society for Testing and Materials) Method F739-96 specifies a test-cell design and procedures for measuring the permeation resistance of chemical protective clothing. Among the specifications are open-loop collection stream flow rates of 0.050 to 0.150 L/min for a gaseous medium. At elevated temperatures the test must be maintained within 1 degree C of the set point. This article presents a critical analysis of the effect of the collection stream flow rate on the measured permeation rate and on the temperature uniformity within the test cell. Permeation tests were conducted on four polymeric glove materials with 44 solvents at 25 degrees C. Flow rates > 0.5 L/min were necessary to obtain accurate steady-state permeation rate (SSPR) values in 25 percent of the tests. At the lower flow rates the true SSPR typically was underestimated by a factor of two or less, but errors of up to 33-fold were observed. No clear relationship could be established between the need for a higher collection stream flow rate and either the vapor pressure or the permeation rate of the solvent, but test results suggest that poor mixing within the collection chamber was a contributing factor. Temperature gradients between the challenge and collection chambers and between the bottom and the top of the collection chamber increased with the water-bath temperature and the collection stream flow rate. Use of a test cell modified to permit deeper submersion reduced the gradients to < or = 0.5 degrees C. It is recommended that all SSPR measurements include verification of the adequacy of the collection stream flow rate. For testing at nonambient temperatures, the modified test cell described here could be used to ensure temperature uniformity throughout the cell.

    Biobased becomes one of the new breakthrough in the smart engineering, especially in biomedical applications, such as tissue engineering that serves as a supporting physical structure to trigger the growth of skin tissue. From various studies which had been done, it was known that the optimal Biobased healed wounds or injuries in a relatively short time. In this study, a Biobased natural polymer based e.g Poly(Lactic Acid) (PLA)/Chitosan Nanocomposites was made. PLA was synthesized from saba banana (Musa acuminata) as raw material using Ring-Opening Polymerization (ROP) method. PLA was mixed with Chitosan with Chitosan concentration variations of 1%, 3%, and 5% to form a nanocomposites. The analysis result showed that Chitosan concentration in PLA/Chitosan Nanocomposites sample affected the value of tensile strength. The highest value of tensile strength was obtained on a sample of 100 ml volume with a concentration of 3%, which was 120.396 MPa. The highest percentage of elongation was obtained in 100 ml volume sample with 5% concentration, which was 26.3686%. In the hydrophilicity test, the highest percentage of water absorption was obtained in a 200 ml volume sample with 5% concentration, which was 44.615%. The addition of Chitosan to the sample affected the functional group bonding, where there was a functional group of NH2 at the wave number of 2923.92 cm-1. The sample characteristics based on water absorption indicated that the sample was potentially to be used as Biobased construction material.

  12. Advanced biomaterials from renewable resources: An investigation on cellulose nanocrystal composites and carbon dioxide extraction of rendered materials

    Orellana, Jose Luis

    The annual global consumption of petroleum-based plastics is approximately 280 million tons and is impacting the sustainability of our planet and prosperity of future generations. One solution is the development of bio-based polymer materials with advanced properties for commercial applications. Therefore, the ultimate goal of this dissertation is to investigate the properties of new bio-based materials for broader applications. This dissertation includes two research areas: cellulose nanocomposites, and CO2 extractions of rendered fat. In the first half, cellulose nanocrystals (CNCs), which exhibit excellent mechanical and optical properties, were investigated for the reinforcement of a biodegradable polymer. The properties of these nanocomposites were studied to intellectually contribute to the understanding of the reinforcement mechanisms of CNC nanocomposites. In the second half, a more efficient and greener extraction of fat from rendered materials (RMs) was explored to broaden their potential applications, which include protein-based polymers and biofuels. Since CNCs are hydrophilic, surface modification with various surfactants was first accomplished in this research, increasing the dispersion stability in non-polar solvents by at least a month. Only 1 wt.% of surfactant with respect to CNCs was needed to afford a significant increase in the CNC stability, representing a much lower percentage than the values reported in the literature. Moreover, these CNCs showed the ability to selfassemble into local liquid crystal structures, a potential advantage for polymer reinforcement. CNCs were subsequently investigated as an additive for polylactic acid (PLA), which is the most widely used synthetic biopolymer in the market. CNC addition yielded a 61% increase in toughness at 1 wt.% CNC load. The tensile strength and modulus were not affected by the CNC addition, addressing one of the most frequent issues in the toughening of polymers. In addition, polarized

    The project Climate protection, natural resources management and soil improvement by combined Energetic and Material Utilization of lignocellulosic agricultural WAstes and residues (CEMUWA) was implemented with long-term partners from Egypt and Germany leaded by the Department Waste Management and Material Flow from September 2011 until October 2013. Aim of the project was the development of technologies for the utilization of agricultural wastes and residues at the example of rice straw, with the focus on the energetic and material use. In the long term a contribution to climate protection and natural resource management could be reached. The focus was on investigations in the field of biogas, ethanol and butanol production including pretreatment as well as the material use in horticulture. The results show that the biogas and ethanol production with adapted pretreatments of rice straws is possible. The technical adaptation of a biogas plant (eo-digestion) would be associated with about 20% higher investment costs and higher operating costs with an approximately 15% higher energy demand. In Germany, however, this may still economically by the substitution of expensive or difficult available energy crops (reduction of substrate costs by 30 to 35% for a 600 kWel-BGP using maize silage). The investigated solutions for material use in Egypt showed good results, which in some cases exceeded the expectations. By the use of rice straw imported peat substrates could be substitute or irrigation water saved, what is ecologically and economically useful. The production of ethanol from rice straw was implemented on laboratory scale and preconditions for investigations in semi-industrial and partly pilot scale were created. The bilateral project'' was funded in the framework of the German-Egypt-Research-Fond (GERF) by the German Federal Ministry of Education and Research (BMBF) and the Egyptian Science and Technology Development Fund in Egypt (STDF).

    2009-03-01

    The Bio-based Raw Materials Platform (PGG), part of the Energy Transition in The Netherlands, commissioned the Agricultural Economics Research Institute (LEI) and the Copernicus Institute of Utrecht University to conduct research on the macro-economic impact of large scale deployment of biomass for energy and materials in the Netherlands. Two model approaches were applied based on a consistent set of scenario assumptions: a bottom-up study including technoeconomic projections of fossil and bio-based conversion technologies and a topdown study including macro-economic modelling of (global) trade of biomass and fossil resources. The results of the top-down and bottom-up modelling work are reported separately. The results of the synthesis of the modelling work are presented in the main report. This report (part 1) presents scenarios for future biomass use for energy and materials, and analyses the consequences on energy supply, chemical productions, costs and greenhouse gas (GHG) emissions with a bottom-up approach. The bottom-up projections, as presented in this report, form the basis for modelling work using the top-down macro-economic model (LEITAP) to assess the economic impact of substituting fossil-based energy carriers with biomass in the Netherlands. The results of the macro-economic modelling work, and the linkage between the results of the bottom-up and top-down work, will be presented in the top-down economic part and synthesis report of this study

    The aim of the study was to determine the role of patch metal allergy testing to select bar material for the Nuss procedure. An IRB-approved (11-04-WC-0098) single institution retrospective, cohort study comparing selective versus routine patch metal allergy testing to select stainless steel or titanium bars for Nuss repair was performed. In Cohort A (9/2004-1/2011), selective patch testing was performed based on clinical risk factors. In Cohort B (2/2011-9/2014), all patients were patch tested. The cohorts were compared for incidence of bar allergy and resultant premature bar loss. Risk factors for stainless steel allergy or positive patch test were evaluated. Cohort A had 628 patients with 63 (10.0%) selected for patch testing, while all 304 patients in Cohort B were tested. Over 10years, 15 (1.8%) of the 842 stainless steel Nuss repairs resulted in a bar allergy, and 5 had a negative preoperative patch test. The incidence of stainless steel bar allergy (1.8% vs 1.7%, p=0.57) and resultant bar loss (0.5% vs 1.3%, p=0.23) was not statistically different between cohorts. An allergic reaction to a stainless steel bar or a positive patch test was more common in females (OR=2.3, pbar allergies occur at a low incidence with either routine or selective patch metal allergy testing. If selective testing is performed, it is advisable in females and patients with a personal or family history of metal sensitivity. A negative preoperative patch metal allergy test does not preclude the possibility of a postoperative stainless steel bar allergy. Level III Treatment Study and Study of Diagnostic Test.

  18. Prioritizing stream types according to their potential risk to receive crop plant material--A GIS-based procedure to assist in the risk assessment of genetically modified crops and systemic insecticide residues.

    Crop plant residues may enter aquatic ecosystems via wind deposition or surface runoff. In the case of genetically modified crops or crops treated with systemic pesticides, these materials may contain insecticidal Bt toxins or pesticides that potentially affect aquatic life. However, the particular exposure pattern of aquatic ecosystems (i.e., via plant material) is not properly reflected in current risk assessment schemes, which primarily focus on waterborne toxicity and not on plant material as the route of uptake. To assist in risk assessment, the present study proposes a prioritization procedure of stream types based on the freshwater network and crop-specific cultivation data using maize in Germany as a model system. To identify stream types with a high probability of receiving crop materials, we developed a formalized, criteria-based and thus transparent procedure that considers the exposure-related parameters, ecological status--an estimate of the diversity and potential vulnerability of local communities towards anthropogenic stress--and availability of uncontaminated reference sections. By applying the procedure to maize, ten stream types out of 38 are expected to be the most relevant if the ecological effects from plant-incorporated pesticides need to be evaluated. This information is an important first step to identifying habitats within these stream types with a high probability of receiving crop plant material at a more local scale, including accumulation areas. Moreover, the prioritization procedure developed in the present study may support the selection of aquatic species for ecotoxicological testing based on their probability of occurrence in stream types having a higher chance of exposure. Finally, this procedure can be adapted to any geographical region or crop of interest and is, therefore, a valuable tool for a site-specific risk assessment of crop plants carrying systemic pesticides or novel proteins, such as insecticidal Bt toxins, expressed

    In this paper technological aspects of a synthesis of phospho-olivine LiFePO{sub 4} based composite cathode materials for lithium batteries are presented. An effective synthesis route yielding a highly conductive composite cathode material was developed. The structural, electrical and electrochemical properties of these materials were investigated. It was shown that the enhanced conductivity of the cathode material is due to the presence of a thin layer of the reduced material which has metallic properties, which is formed on the grain surfaces of the phospho-olivine. We propose a synthesis route yielding LiFePO{sub 4}/Fe{sub 2}P composite material. (author)

  3. Heavy metal speciation in solid-phase materials from a bacterial sulfate reducing bioreactor using sequential extraction procedure combined with acid volatile sulfide analysis.

    Jong, Tony; Parry, David L

    2004-04-01

    Heavy metal mobility, bioavailability and toxicity depends largely on the chemical form of metals and ultimately determines potential for environmental pollution. For this reason, determining the chemical form of heavy metals and metalloids, immobilized in sludges by biological mediated sulfate reduction, is important to evaluate their mobility and bioavailability. A modified Tessier sequential extraction procedure (SEP), complemented with acid volatile sulfide (AVS) and simultaneous extracted metals (SEM) measurements, were applied to determine the partitioning of five heavy metals (defined as Fe, Ni, Zn and Cu, and the metalloid As) in anoxic solid-phase material (ASM) from an anaerobic, sulfate reducing bioreactor into six operationally defined fractions. These fractions were water soluble, exchangeable, bound to carbonates (acid soluble), bound to Fe-Mn oxides (reducible), bound to organic matter and sulfides (oxidizable) and residual. It was found that the distribution of Fe, Ni, Zn, Cu and As in ASM was strongly influenced by its association with the above solid fractions. The fraction corresponding to organic matter and sulfides appeared to be the most important scavenging phases of As, Fe, Ni, Zn and Cu in ASM (59.8-86.7%). This result was supported by AVS and SEM (Sigma Zn, Ni and Cu) measurements, which indicated that the heavy metals existed overwhelmingly as sulfides in the organic matter and sulfide fraction. A substantial amount of Fe and Ni at 16.4 and 20.1%, respectively, were also present in the carbonate fraction, while an appreciable portion of As (18.3%) and Zn (19.4%) was bound to Fe-Mn oxides. A significant amount of heavy metals was also associated with the residual fraction, ranging from 2.1% for Zn to 18.8% for As. Based on the average total extractable heavy metal (TEHM) values, the concentration of heavy metals in the ASM was in the order of Cu > Ni > Zn > Fe > As. If the mobility and bioavailability of heavy metals are assumed to be

  9. Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

    Williams, Richard L.; Yore, Larry D.

    Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

  10. Development of analytical procedures for determination of total chromium by quadrupole ICP-MS and high-resolution ICP-MS, and hexavalent chromium by HPLC-ICP-MS, in different materials used in the automotive industry.

    Séby, F; Gagean, M; Garraud, H; Castetbon, A; Donard, O F X

    2003-10-01

    A European directive was recently adopted limiting the use of hazardous substances such as Pb, Hg, Cd, and Cr(VI) in vehicle manufacturing. From July 2003 a maximum of 2 g Cr(VI) will be authorised per vehicle in corrosion-preventing coatings of key components. As no standardised procedures are available to check if produced vehicles are in agreement with this directive, the objective of this work was to develop analytical procedures for total chromium and Cr(VI) determination in these materials. The first step of this study was to optimise digestion procedures for total chromium determination in plastic and metallic materials by inductively coupled plasma mass spectrometry (ICP-MS). High resolution (HR) ICP-MS was used to examine the influence of polyatomic interferences on the detection of the (52)Cr(+) and (53)Cr(+) isotopes. If there was strong interference with m/ z 52 for plastic materials, it was possible to use quadrupole ICP-MS for m/ z 53 if digestions were performed with HNO(3)+H(2)O(2). This mixture was also necessary for digestion of chromium from metallic materials. Extraction procedures in alkaline medium (NH(4)(+)/NH(3) buffer solution at pH 8.9) assisted by sonication were developed for determining Cr(VI) in four different corrosion-preventing coatings by HPLC-ICP-MS. After optimisation and validation with the only solid reference material certified for its Cr(VI) content (BCR 545; welding dusts), the efficiency of this extraction procedure for screw coatings was compared with that described in the EN ISO 3613 standard generally used in routine laboratories. For coatings comprising zinc and aluminium passivated in depth with chromium oxides the extraction procedure developed herein enabled determination of higher Cr(VI) concentrations. This was also observed for the screw covered with a chromium passivant layer on zinc-nickel. For coating comprising a chromium passivant layer on alkaline zinc the standardized extraction procedure was more efficient

  14. Procedures for the accounting and control of nuclear materials in large research centres, as related to the needs of international safeguards

    Kotte, U.; Bueker, H.; Stein, G.

    1976-07-01

    In signatory states of the Non-Proliferation Treaty nuclear material is subject to the supervision of the International Atomic Energy Agency. The IAEA safeguards concept intended for nuclear material has, so far, been predominantly applied to nuclear facilities of the nuclear fuel cycle. It is the aim of this report to consider the applicability of these control measures to a nuclear research centre. The report refers to the concrete example of the Juelich Nuclear Research Centre (KFA). The particular features of a nuclear research centre and the handling of nuclear material in the KFA are described. A review is given of the various licence areas and permitted handling quantities as well as of the inventories and flow of nuclear material. The concept of a control system for a nuclear research centre satisfying the operator's requirements, national requirement and international obligations at the same time is developed along these lines. The essential characteristic of the concept is a far-reaching clarity of the distribution of nuclear material items within the Nuclear Research Centre. The clarity desired will be achieved by means of an integrated accountancy system processing all necessary data with the aid of a central computer and remote terminals. The availability of information is based on differentiated material acountancy in conjunction with adequate measurement of nuclear material data. In the case of the KFA two groups are formed by research reactors and critical assemblies. Research institutes and central departments the permitted handling quantities of which do not exceed 5 eff.kg constitute a further group. Two further groups are formed for cases where the permitted handling quantities are above or below 1 eff.kg. The report shows the safeguards measures that can be applied in certain circumstances and conditions in a nuclear research centre

    Climate change, pollution, and energy insecurity are among the greatest problems of our time. Addressing them requires major changes in our energy infrastructure. Here, we analyze the feasibility of providing worldwide energy for all purposes (electric power, transportation, heating/cooling, etc.) from wind, water, and sunlight (WWS). In Part I, we discuss WWS energy system characteristics, current and future energy demand, availability of WWS resources, numbers of WWS devices, and area and material requirements. In Part II, we address variability, economics, and policy of WWS energy. We estimate that {approx}3,800,000 5 MW wind turbines, {approx}49,000 300 MW concentrated solar plants, {approx}40,000 300 MW solar PV power plants, {approx}1.7 billion 3 kW rooftop PV systems, {approx}5350 100 MW geothermal power plants, {approx}270 new 1300 MW hydroelectric power plants, {approx}720,000 0.75 MW wave devices, and {approx}490,000 1 MW tidal turbines can power a 2030 WWS world that uses electricity and electrolytic hydrogen for all purposes. Such a WWS infrastructure reduces world power demand by 30% and requires only {approx}0.41% and {approx}0.59% more of the world's land for footprint and spacing, respectively. We suggest producing all new energy with WWS by 2030 and replacing the pre-existing energy by 2050. Barriers to the plan are primarily social and political, not technological or economic. The energy cost in a WWS world should be similar to that today. - Research highlights: {yields} Replacing world energy with wind, water, and sun (WWS) reduces world power demand 30%. {yields} WWS for world requires only 0.41% and 0.51% more world land for footprint and spacing, respectively. {yields} Practical to provide 100% new energy with WWS by 2030 and replace existing energy by 2050.

    2014-01-01

    The idea of definitive methods based on radiochemical neutron activation analysis (RNAA), consists in combination of neutron activation with the highly selective and quantitative post-irradiation isolation of the desired radionuclide by column chromatography followed by γ-ray spectrometric measurement. The principles of construction of such methods, which were devised in the Institute of Nuclear Chemistry and Technology, are reminded and the significance of these methods for analytical quality assurance is emphasized. According to VIM 3 nomenclature these methods may be called: ratio primary reference measurement procedures (RPRMPs). RPRMP for the determination of Se is briefly presented and its use for checking the accuracy of 'assigned values' established by expert laboratories in some proficiency tests, is demonstrated

  5. Evaluation of the technical and financial feasibility for the change of material of a platinum coil used in guidewires for interventional cardiology procedures in a company producing medical devices in Costa Rica

    Soto Guzman, Mariana

    2014-01-01

    An evaluation is made of the technical and financial feasibility for the change of material of a platinum coil used in guidewires for procedures of cardiological intervention in a company producing medical devices in Costa Rica. The proposed exchange rate on the product has already was marketed. A validation and verification of the design are performed again for the characteristics impacted, in addition to notify the regulatory bodies of the material change and have its prior approval commercialization of the modified product. A radiopacity study of the proposed materials is carried out to evaluate the materials as well as a consultation with suppliers approved by the company to verify the availability of candidate materials. The load of the palladium spring is evaluated with respect to the Platinum spring to three defined extensions and is determined. The project has proposed to save $663 897 for the Palladium coil and $739 175 for the 'A alloy' coil composed mainly of Palladium. The project can be developed according to the financial study, since the savings gains are greater than the investment made by the company for the execution of the product. Deeper radiopacity tests are recommended to perform. Comparison of the current spring with those proposed under fluoroscopy in the field of application. Suppliers' studies have shown that the percentage of visibility of palladium is decreased in the energetic environment in which medical interventions are carried out and the guidewires are used.

  6. Self managing experiment resources

    Stagni, F; Ubeda, M; Charpentier, P; Tsaregorodtsev, A; Romanovskiy, V; Roiser, S; Graciani, R

    2014-01-01

    Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

  8. Experimental study on the use of spacer foils in two-step putty and wash impression procedures using silicone impression materials.

    Mann, Karsten; Davids, Andreas; Range, Ursula; Richter, Gert; Boening, Klaus; Reitemeier, Bernd

    2015-04-01

    The 2-step putty and wash impression technique is commonly used in fixed prosthodontics. However, cutting sluiceways to allow the light-body material to drain is time-consuming. A solution might be the use of a spacer foil. The purpose of this study was to evaluate the influence of spacer foil on the margin reproduction and dimensional accuracy of 2-step putty and wash impressions. Two methods of creating space for the wash material in a 2-step putty and wash impression were compared: the traditional cutout technique and a spacer foil. Eleven commercially available combinations of silicone impression materials were included in the study. The impressions and the cast production were carried out under standardized conditions. All casts were measured with a 3-dimensional (3D) coordinate measuring machine. Preparation margin reproduction and the diameters and spacing of the stone cast dies were measured (α=.05). The 2 methods showed significant differences (P<.05) in the reproduction of the preparation margins (complete reproduction cutout, 90% to 98%; foil, 74% to 91%). The use of a foil resulted in greater dimensional accuracy of the cast dies compared to the cutout technique. Cast dies from the cutout technique were significantly smaller than the metallic original cast (cutout median, 4.55 mm to 4.61 mm; foil median, 4.61 to 4.64). Spacing between the dies revealed only a few additional significant differences between the techniques. When spacer foils were used, dies were obtained that better corresponded to the original tooth.

  10. The Kjeldahl method as a primary reference procedure for total protein in certified reference materials used in clinical chemistry. I. A review of Kjeldahl methods adopted by laboratory medicine.

    Chromý, Vratislav; Vinklárková, Bára; Šprongl, Luděk; Bittová, Miroslava

    2015-01-01

    We found previously that albumin-calibrated total protein in certified reference materials causes unacceptable positive bias in analysis of human sera. The simplest way to cure this defect is the use of human-based serum/plasma standards calibrated by the Kjeldahl method. Such standards, commutative with serum samples, will compensate for bias caused by lipids and bilirubin in most human sera. To find a suitable primary reference procedure for total protein in reference materials, we reviewed Kjeldahl methods adopted by laboratory medicine. We found two methods recommended for total protein in human samples: an indirect analysis based on total Kjeldahl nitrogen corrected for its nonprotein nitrogen and a direct analysis made on isolated protein precipitates. The methods found will be assessed in a subsequent article.

  12. Environmental procedures

    1992-01-01

    The European Bank has pledged in its Agreement to place environmental management at the forefront of its operations to promote sustainable economic development in central and eastern Europe. The Bank's environmental policy is set out in the document titled, Environmental Management: The Bank's Policy Approach. This document, Environmental Procedures, presents the procedures which the European Bank has adopted to implement this policy approach with respect to its operations. The environmental procedures aim to: ensure that throughout the project approval process, those in positions of responsibility for approving projects are aware of the environmental implications of the project, and can take these into account when making decisions; avoid potential liabilities that could undermine the success of a project for its sponsors and the Bank; ensure that environmental costs are estimated along with other costs and liabilities; and identify opportunities for environmental enhancement associated with projects. The review of environmental aspects of projects is conducted by many Bank staff members throughout the project's life. This document defines the responsibilities of the people and groups involved in implementing the environmental procedures. Annexes contain Environmental Management: The Bank's Policy Approach, examples of environmental documentation for the project file and other ancillary information

  13. Agency procedures for the NRC incident response plan. Final report

    1983-02-01

    The NRC Incident Response Plan, NUREG-0728/MC 0502 describes the functions of the NRC during an incident and the kinds of actions that comprise an NRC response. The NRC response plan will be activated in accordance with threshold criteria described in the plan for incidents occurring at nuclear reactors and fuel facilities involving materials licensees; during transportation of licensed material, and for threats against facilities or licensed material. In contrast to the general overview provided by the Plan, the purpose of these agency procedures is to delineate the manner in which each planned response function is performed; the criteria for making those response decisions which can be preplanned; and the information and other resources needed during a response. An inexperienced but qualified person should be able to perform functions assigned by the Plan and make necessary decisions, given the specified information, by becoming familiar with these procedures. This rule of thumb has been used to determine the amount of detail in which the agency procedures are described. These procedures form a foundation for the training of response personnel both in their normal working environment and during planned emergency exercises. These procedures also form a ready reference or reminder checklist for technical team members and managers during a response

    1982-01-01

    The modern counting instrumentation has largely obviated the need for separation processes in the radiochemical analysis but problems in low-level radioactivity measurement, environmental-type analyses, and special situations caused in the last years a renaissance of the need for separation techniques. Most of the radiochemical procedures, based on the classic works of the Manhattan Project chemists of the 1940's, were published in the National Nuclear Energy Series (NNES). Improvements such as new solvent extraction and ion exchange separations have been added to these methods throughout the years. Recently the Los Alamos Group have reissued their collected Radiochemical Procedures containing a short summary and review of basic inorganic chemistry - 'Chemistry of the Elements on the Basis of Electronic Configuration'.

  18. Standard and applied material testing methods of austenitic CrNi stainless steels in different nitric acid media - procedures and results

    Leistikow, S.; Kraft, R.; Schanz, G.

    1989-07-01

    Extended ASTM Standard Huey Testing has been performed in at 120 0 C boiling 14.4 molar (65%) nitric acid during 15 periods (15x48 = 720 h duration) for quality control of numerous commercial nitric acid resistant austenitic CrNi steels. It was shown how sensitively the chosen testing conditions could differentiate between CrNi steels of the same nominal composition as specified for DIN W.Nr. 1.4306 (AISI Type 304 L), but with varying residual element contents. Within an attempt to differentiate within this group of steels by application of electrochemical methods, potentiostatic tests at 1250 mV in nitric acid of equal concentration and temperature were able to detect remarkable differences in corrosion behaviour already after one hour. Another approach, more typical for the electrochemical potentials during materials application in reprocessing plants of nuclear fuel, gave preference to long-term immersion tests, which were performed in nitric acid of lower concentration and temperature. Reference tests in pure 7 molar, 90 0 C nitric acid could only reveal by surface attack small differences in steel quality by exposures of 720 h duration. To shorten the test time by an increase of the redox potential chromium (VI) ions were added to the nitric acid. In a solution of 0,5 g Gr (VI)/l at 90 0 C remarkable differences in corrosion behavior of the steels - similar to the Huey test results - became measurable by means of gravimetry and metallography already during a short-term exposure of 24-71 h.

    In our globalized world, the amount of cross-national communication increases rapidly, which also calls for easy access to multi-lingual high quality terminological resources. Sharing of terminology resources is currently becoming common practice, and efficient strategies for integration...... – or merging – of terminology resources are strongly needed. This paper discusses prerequisites for successful merging with the focus on identification of candidate duplicates of a subject domain found in the resources to be merged, and it describes automatic merging strategies to be applied to such duplicates...... in electronic terminology resources. Further, some perspectives of manual, supplementary assessment methods supporting the automatic procedures are sketched. Our considerations are primarily based on experience gained in the IATE and EuroTermBank projects, as merging was a much discussed issue in both projects....

  3. Optimal allocation of international atomic energy agency inspection resources

    Markin, J.T.

    1987-01-01

    Each year the Department of Safeguards of the International Atomic Energy Agency (IAEA) conducts inspections to confirm that nuclear materials and facilities are employed for peaceful purposes. Because of limited inspection resources, however, the IAEA cannot fully attain its safeguards goals either quantitatively as measured by the inspection effort negotiated in the facility attachments or qualitatively as measured by the IAEA criteria for evaluating attainment of safeguards goals. Under current IAEA procedures the allocation of inspection resources assigns essentially equal inspection effort to facilities of the same type. An alternative approach would incorporate consideration of all material categories and facilities to be assigned inspection resources when allocating effort to a particular facility. One such method for allocating inspection resources is based on the IAEA criteria. The criteria provide a framework for allocating inspection effort that includes a ranking of material types according to their safeguards importance, an implicit definition of inspection activities for each material and facility type, and criteria for judging the attainment of safeguards goals in terms of the quality and frequency of these inspection activities. This framework is applicable to resource allocation for an arbitrary group of facilities such as a state's fuel cycle, the facilities inspected by an operations division, or all of the facilities inspected by the IAEA

  4. Bioresists from renewable resources as sustainable photoresins for 3D laser microlithography: material synthesis, cross-linking rate and characterization of the structures

    Stereolithography (SLA) allows rapid and accurate materialization of computer aided design (CAD) models into real objects out of photoreactive resin. Nowadays this technology has evolved to a widespread simple and flexible personal tabletop devices - three dimensional (3D) optical printers. However, most 3D SLA printers use commercially available resins which are not cheap and of limited applicability, often of unknown chemical ingredients and fixed to certain mechanical properties. For advanced research, it is important to have bio-resin appropriate to 3D print microscaffolds for cell proliferation and tissue engineering. To fill these requirements would be to use sources from bio-based resins, which can be made of naturally derived oils. Chosen substances glycerol diglycidyl ether and epoxidized linseed oil can be obtained from renewable recourses, are biodegradable and can be synthesized as sustainable photosensitive materials.1 UV (ff=365 nm) lithography was employed to determine their photocross-linking rate and cured material properties. After exposing material to UV radiation through a micro-patterned amplitude mask selective photopolymerization was observed. Acetone was used as a solvent to dissolve UV unaffected area and leaving only exposed microstructures on the substrate. The resins were compared to FormLabs Form Clear and Autodesk Ember PR48 as standard stereolithography materials. Finally, 3D microporous woodpile scaffolds were printed out of commercial resins and cells adhesion in them were explored.

    2011-04-15

    The demand for both energetic and non-energetic raw materials has been increasing continuously during the past few decades. Especially during the last few years, the threat of structural shortages of supply or availability came into focus. The discussion is highly controversial, especially in the case of petroleum. This sub-report presents an analysis of the supply situation of energetic and non-energetic raw materials, i.e. petroleum, coal and nuclear fuels on the one hand as well as iron and steel, chromium, nickel, cobalt, aluminium, magnesium, copper, platinum and platinum metals, industrial minerals, boron salts, phosphate, zirconium and zirconium oxide on the other hand. It is important to discuss also regional availability patterns in order to arrive at a regional picture of potential supply risks and resulting conflicts over raw materials as this is the best way to assess the danger of impending conflicts.

  6. Impact of pozzolanic binder addition on stabilization of polluted dredged sediments on its potential reuse as a new material resource for road construction in Basse Normandie, France

    Silitonga, E.

    2018-02-01

    Due to the increase of the amount of marine dredged sediments (MDS) and the cost of managing the disposal site is very high, a reutilization of dredged sediment is urgently needed in France. The primary goal of this research is to find a domain for reuse of MDS materials as a new material regarding the environmental issues, and other requirement needed. In this study, the MDS was used as replacement material in road construction. Hence, various tests need to be realized to identify if MDS could achieve the requirement needed in this domain. The secondary objective is to enhance the geotechnical characteristic and to reduce the pollution content of the MDS, by incorporating binders and sediments, and revealed the geotechnical characteristic. The geotechnical test result shows that the stabilization by hydraulics binders improve the geotechnical characteristic and could fulfil the requirement needed. The present of Fly Ash and Silica Fume in this study is aimed to reduce the pollution level, especially the heavy metal content. After the geotechnical study in laboratory results shows as expected then the study to identify the chemical characteristic was realized. In order to evaluate the environmental impacts, leaching test was performed. The Leaching test result shows that with 7% of Silica Fume and 10% of Fly Ash capable to fulfil the criteria needed, hence, the use of MDS is consider safe in term of geotechnical and environmental impact, as a new material in road construction

The simulator is designed based on the JMTR (Japan Materials Testing Reactor), and it simulates operation, irradiation tests and various kinds of anticipated operational transients and accident conditions caused by the reactor and irradiation facilities. The development of the simulator was sponsored by the Japanese government as one of the specialized projects of advanced research infrastructure in order to promote basic as well as applied researches. This report summarizes the simulation components, hardware specification and operation procedure of the simulator. (author)

  9. Optimal allocation of International Atomic Energy Agency inspection resources

    Markin, J.T.

    1987-12-01

    The Safeguards Department of the International Atomic Energy Agency (IAEA) conducts inspections to assure the peaceful use of a state's nuclear materials and facilities. Because of limited resources for conducting inspections, the careful disposition of inspection effort among these facilities is essential if the IAEA is to attain its safeguards goals. This report describes an optimization procedure for assigning an inspection effort to maximize attainment of IAEA goals. The procedure does not require quantitative estimates of safeguards effectiveness, material value, or facility importance. Instead, the optimization is based on qualitative, relative prioritizations of inspection activities and materials to be safeguarded. This allocation framework is applicable to an arbitrary group of facilities such as a state's fuel cycle, the facilities inspected by an operations division, or all of the facilities inspected by the IAEA

  10. LHCb: Self managing experiment resources

    Stagni, F

    2013-01-01

    Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System ( Resource Status System ) delivering real time informatio...

  11. Municipal Solid Waste Resources

    None

    2016-06-01

    Municipal solid waste (MSW) is a source of biomass material that can be utilized for bioenergy production with minimal additional inputs. MSW resources include mixed commercial and residential garbage such as yard trimmings, paper and paperboard, plastics, rubber, leather, textiles, and food wastes. Waste resources such as landfill gas, mill residues, and waste grease are already being utilized for cost-effective renewable energy generation. MSW for bioenergy also represents an opportunity to divert greater volumes of residential and commercial waste from landfills.

  12. Pretreatment procedures

    Anon.

    1989-01-01

    It is frequently in the patient's best interest that radiation treatments are initiated soon after the decision to treat is made. However, it is essential to good radiation therapy that the patient's treatment course be planned and beam-modifying devices be fabricated with utmost care prior to treatment. The objectives of the treatment, along with the treatment parameters and techniques necessary to achieve these objectives, must be discussed prior to initiating planning procedures. Determination of the target volume is made by the radiation oncologist; this is based on knowledge of the history of the tumor, the patterns of spread of the disease, and on diagnostic findings during the work-up of each patient. It is then necessary to obtain several measurements of the patient and also to identify the position of the target volume and of adjacent normal organs with respect to known external skin marks before the actual treatment planning is begun. Such localization can be done through several methods. The two most commonly used methods are radiographic and computed tomography (CT), both of which are discussed in this chapter. The measurements often include contours of the patient's external surface, usually in the axial plane of the central axis of the beam, and often in multiple levels within the region to be treated. Three dimensional localization and treatment planning requires thorough understanding of geometry as well as of patient positioning and immobilization. This chapter attempts to clarify some of these complicated but essential preparations for treatment

    Intravenous access procedures in children are considered to be one of the most stressful because it is invasive, and the use of needles generates anxiety, insecurity, and fear. Playful strategies using dolls and even the materials used for venipuncture can assist children in understanding, accepting, and coping with the procedure. Field research was developed on the applicability of the therapeutic toy in the preparation of preschool children for venipuncture procedure based on the protocol developed by Martins, Ribeiro, Borba, and Silva (2001) and Kiche and Almeida (2009). The study was done in a private hospital in Greater São Paulo, Brazil, with 10 children ages 3 to 6 years. Data were gathered through observation and questionnaires completed by the children's adult guardians. Before the activity, the children showed fearful facial expressions, used monosyllabic responses, and avoided looking at the health care professional. After the strategy of using therapeutic toy dolls and puppets, 40% of the children calmly accepted the venipuncture procedure, and 100% showed a change to their initial negative reaction, became more communicative and cooperative, and participated and interacted with researchers, even after the end of the activity and procedure. The strategy of therapeutic toys helps make an unfamiliar environment, strangers, and a procedure characterized as painful and difficult less stressful. Pediatric nurses are in a good position to use this resource to offer more humanized care to children.

  17. Space and Planetary Resources

    Abbud-Madrid, Angel

    2018-02-01

    The space and multitude of celestial bodies surrounding Earth hold a vast wealth of resources for a variety of space and terrestrial applications. The unlimited solar energy, vacuum, and low gravity in space, as well as the minerals, metals, water, atmospheric gases, and volatile elements on the Moon, asteroids, comets, and the inner and outer planets of the Solar System and their moons, constitute potential valuable resources for robotic and human space missions and for future use in our own planet. In the short term, these resources could be transformed into useful materials at the site where they are found to extend mission duration and to reduce the costly dependence from materials sent from Earth. Making propellants and human consumables from local resources can significantly reduce mission mass and cost, enabling longer stays and fueling transportation systems for use within and beyond the planetary surface. Use of finely grained soils and rocks can serve for habitat construction, radiation protection, solar cell fabrication, and food growth. The same material could also be used to develop repair and replacement capabilities using advanced manufacturing technologies. Following similar mining practices utilized for centuries on Earth, identifying, extracting, and utilizing extraterrestrial resources will enable further space exploration, while increasing commercial activities beyond our planet. In the long term, planetary resources and solar energy could also be brought to Earth if obtaining these resources locally prove to be no longer economically or environmentally acceptable. Throughout human history, resources have been the driving force for the exploration and settling of our planet. Similarly, extraterrestrial resources will make space the next destination in the quest for further exploration and expansion of our species. However, just like on Earth, not all challenges are scientific and technological. As private companies start working toward

  18. Electronic procedure distribution

    Slone, B.J. III; Richardson, C.E.

    1993-01-01

    Printed procedures can offer a mix of text and graphic information that improves readability and increases understanding. A typical procedure uses illustrations and graphics to clarify concepts, a variety of type styles and weights to make it easier to find different topics and sections, white space to improve readability, and familiar navigational clues such as page numbers and topic headers. Initially, electronic procedure systems had limited typeface options, often only a single typeface, with no capability for enhancing readability by varying type size bolding, italicizing, or underlining, and no ability to include graphics. Even recently, many text-only electronic procedures were originally created in a modern What-You-See-Is-What-You-Get (WYSI-WYG) document authoring system, only to be converted to pages and pages of plain type for electronic distribution. Given the choice of paper or on-line producers, most users have chosen paper for its readability. But current-generation electronic document systems that use formatted text and embedded graphics offer users vastly improved readability. Further, they are offering ever-better search tools to enable rapid location of material of interest

  19. Water Resources

    Abira, M.A.

    1997-01-01

    Water is essential for life and ecological sustenance; its availability is essential component of national welfare and productivity.The country's socio-economic activities are largely dependent on the natural endowment of water resources. Kenya's water resources comprises of surface waters (rivers, lakes and wetlands) and ground water. Surface water forms 86% of total water resources while the rest is ground water Geological, topographical and climatic factors influence the natural availability and distribution of water with the rainfall distribution having the major influence. Water resources in Kenya are continuously under threat of depletion and quality degradation owing to rising population, industrialization, changing land use and settlement activities as well as natural changes. However, the anticipated climate change is likely to exacerbate the situation resulting in increased conflict over water use rights in particular, and, natural resource utilisation in general. The impacts of climate change on the water resources would lead to other impacts on environmental and socio-economic systems

  20. Towards a generic procedure for the detection of relevant contaminants from waste electric and electronic equipment (WEEE) in plastic food-contact materials: a review and selection of key parameters.

    Puype, Franky; Samsonek, Jiří; Vilímková, Věra; Kopečková, Šárka; Ratiborská, Andrea; Knoop, Jan; Egelkraut-Holtus, Marion; Ortlieb, Markus; Oppermann, Uwe

    2017-10-01

    Recently, traces of brominated flame retardants (BFRs) have been detected in black plastic food-contact materials (FCMs), indicating the presence of recycled plastics, mainly coming from waste electric and electronic equipment (WEEE) as BFRs are one of the main additives in electric applications. In order to evaluate efficiently and preliminary in situ the presence of WEEE in plastic FCMs, a generic procedure for the evaluation of WEEE presence in plastic FCMs by using defined parameters having each an associated importance level has been proposed. This can be achieved by combining parameters like overall bromine (Br) and antimony (Sb) content; additive and reactive BFR, rare earth element (REE) and WEEE-relevant elemental content and additionally polymer purity. In most of the cases, the WEEE contamination could be confirmed by combining X-ray fluorescence (XRF) spectrometry and thermal desorption/pyrolysis gas chromatography-mass spectrometry (GC-MS) at first. The Sb and REE content did not give a full confirmation as to the source of contamination, however for Sb the opposite counts: Sb was joined with elevated Br signals. Therefore, Br at first followed by Sb were used as WEEE precursors as both elements are used as synergetic flame-retardant systems. WEEE-specific REEs could be used for small WEEE (sWEEE) confirmation; however, this parameter should be interpreted with care. The polymer purity by Fourier-transform infrared spectrometer (FTIR) and pyrolysis GC-MS in many cases could not confirm WEEE-specific contamination; however, it can be used for purity measurements and for the suspicion of the usage of recycled fractions (WEEE and non-WEEE) as a third-line confirmation. To the best of our knowledge, the addition of WEEE waste to plastic FCMs is illegal; however, due to lack on screening mechanisms, there is still the breakthrough of such articles onto the market, and, therefore, our generic procedure enables the quick and effective screening of suspicious

  1. Macro-economic impact of large-scale deployment of biomass resources for energy and materials on a national level—A combined approach for the Netherlands

    Hoefnagels, Ric; Banse, Martin; Dornburg, Veronika; Faaij, André

    2013-01-01

    Biomass is considered one of the most important options in the transition to a sustainable energy system with reduced greenhouse gas (GHG) emissions and increased security of enegry supply. In order to facilitate this transition with targeted policies and implementation strategies, it is of vital importance to understand the economic benefits, uncertainties and risks of this transition. This article presents a quantification of the economic impacts on value added, employment shares and the trade balance as well as required biomass and avoided primary energy and greenhouse gases related to large scale biomass deployment on a country level (the Netherlands) for different future scenarios to 2030. This is done by using the macro-economic computable general equilibrium (CGE) model LEITAP, capable of quantifying direct and indirect effects of a bio-based economy combined with a spread sheet tool to address underlying technological details. Although the combined approach has limitations, the results of the projections show that substitution of fossil energy carriers by biomass, could have positive economic effects, as well as reducing GHG emissions and fossil energy requirement. Key factors to achieve these targets are enhanced technological development and the import of sustainable biomass resources to the Netherlands. - Highlights: • We analyse large scale production of bioenergy and biochemicals in the Netherlands. • The scenarios include up to 30% substitution of fossil fuels by biomass in 2030. • Resulting in strong greenhouse gas savings and positive macro-economic effects. • Large amounts of imported biomass are required to meet the domestic demand. • This requires high rates of technological change and strict sustainability criteria

  2. Activities as a research resource

    Carla Regina Silva

    2013-12-01

    Full Text Available Activities play a guiding central role in occupational therapy, articulating to its utilization, the understanding and assessment of its capabilities in numerous and different interventions arising from this field. In this study, we aim to present the use of activities as a research methodology resource. Considering the pathways studied in a master’s research followed by a PhD work, some applications of this resource are reported as a powerful strategy of investigation for the occupational therapy researcher. It is about structuring, systematizing, and analyzing the activities proposed in professional practice by the theoretical and methodological rigor used in the research works. It emphasizes how the use of these activities can be considered important data, records, instruments and sources for different research methods, especially for qualitative analyses. Workshop activities were offered in the above mentioned studies; they were used as communication instruments and expressions of personal and collective experiences, supplying data to understand the actions of subjects and collectives. Furthermore, this strategy was applied as spaces of experimentation, learning and expression, where each participant was conceived as an active being of the process, in a way that the proposal could result in democratic experiences that reflected greater interest and participation, and a more complex presentation of the research data. It is worth mentioning that other methodological procedures, which substantiated the analyses and interpretation of the data collected, were also used. It was possible to conclude that activities, mainly as a qualitative research resource, constituted materialities in different languages and expressions that enriched the analyses arising from micro-realities, producing a repertoire of information that supported the interpretations required for the investigative processes.

    2015-07-01

    The project Climate protection, natural resources management and soil improvement by combined Energetic and Material Utilization of lignocellulosic agricultural WAstes and residues (CEMUWA) was implemented with long-term partners from Egypt and Germany leaded by the Department Waste Management and Material Flow from September 2011 until October 2013. Aim of the project was the development of technologies for the utilization of agricultural wastes and residues at the example of rice straw, with the focus on the energetic and material use. In the long term a contribution to climate protection and natural resource management could be reached. The focus was on investigations in the field of biogas, ethanol and butanol production including pretreatment as well as the material use in horticulture. The results show that the biogas and ethanol production with adapted pretreatments of rice straws is possible. The technical adaptation of a biogas plant (eo-digestion) would be associated with about 20% higher investment costs and higher operating costs with an approximately 15% higher energy demand. In Germany, however, this may still economically by the substitution of expensive or difficult available energy crops (reduction of substrate costs by 30 to 35% for a 600 kWel-BGP using maize silage). The investigated solutions for material use in Egypt showed good results, which in some cases exceeded the expectations. By the use of rice straw imported peat substrates could be substitute or irrigation water saved, what is ecologically and economically useful. The production of ethanol from rice straw was implemented on laboratory scale and preconditions for investigations in semi-industrial and partly pilot scale were created. The bilateral project'' was funded in the framework of the German-Egypt-Research-Fond (GERF) by the German Federal Ministry of Education and Research (BMBF) and the Egyptian Science and Technology Development Fund in Egypt (STDF).

    On the basis of the agreement concerning the creation of a combined organization for conducting geological prospecting operations for petroleum and gas in the Baltic Sea in the area of the continental shelf and the floor of the territorial waters of the signatory states of East Germany, Poland, and the USSR, which was signed in 1975, the Petrolbaltik organization ws created. A long time program of cooperation in the areas of energy, fuel, and raw materials foresees that the SEV member states will carry out prospective scientific developments on the use of new sources of energy, including solar, wind, chemical and geothermal forms of energy. Forty-seven scientific and technical organization of the SEV member states are working under the leadership of the Coordination center concerning the problem, ''New methods on the use of coal,'' on the industrial use of the by-products of hte extraction and enrichment of coal, the methods of their coking, and their liquefaction and gasification. The technique of producing alumina and cement from the ash of energy systems, working on coal, as well as from coal heaps is being successfully applied in Hungary.

  11. Francois Loos is presenting a policy bill setting the framework, the phrasing and the resources of the radioactive materials and wastes management

    2006-01-01

    The bill institutes a national radioactive materials and waste management plan and defines a programme and calendar for research and work leading to implementation of this plan, which will comprise three major points: with a view to looking to reduce the quantity of waste, spent nuclear fuels taken from the nuclear power plants will be reprocessed for recycling in the plants; waste which cannot be recycled will be packaged in a robust matrix and then temporarily stored on the surface; after interim storage, waste which cannot be finally disposed of in a surface facility, will be placed in a deep geological reversible repository. In order to monitor each step in this plan, the bill strengthens independent assessment of research and involves greater information of the public. With regard to financing, the bill clarifies the fact that economic development of the departments concerned by research into disposal options and the research itself will be financed by additional taxes on the operators of nuclear installations.

  12. Resource conservation management

    Miller, W.

    1999-01-01

    Resource conservation management is a management program similar to financial management in that its success requires commitment by all levels of the organization to the process as well as an accounting procedure and auditing of critical components. Resource conservation management provides a framework for all elements of efficient building operations and maintenance. The savings connected with the program are principally connected with changes in the way buildings are operated and maintained. Given the reduction in rebates for the installation of energy-efficient equipment, this approach has considerable promise. This paper discusses the evolution of the resource conservation management service and the savings associated with a two-year pilot effort with seven school districts, as well as the critical components of a successful program

  3. Efficiency of performing pulmonary procedures in a shared endoscopy unit: procedure time, turnaround time, delays, and procedure waiting time.

    Verma, Akash; Lee, Mui Yok; Wang, Chunhong; Hussein, Nurmalah B M; Selvi, Kalai; Tee, Augustine

    2014-04-01

    The purpose of this study was to assess the efficiency of performing pulmonary procedures in the endoscopy unit in a large teaching hospital. A prospective study from May 20 to July 19, 2013, was designed. The main outcome measures were procedure delays and their reasons, duration of procedural steps starting from patient's arrival to endoscopy unit, turnaround time, total case durations, and procedure wait time. A total of 65 procedures were observed. The most common procedure was BAL (61%) followed by TBLB (31%). Overall procedures for 35 (53.8%) of 65 patients were delayed by ≥ 30 minutes, 21/35 (60%) because of "spillover" of the gastrointestinal and surgical cases into the time block of pulmonary procedure. Time elapsed between end of pulmonary procedure and start of the next procedure was ≥ 30 minutes in 8/51 (16%) of cases. In 18/51 (35%) patients there was no next case in the room after completion of the pulmonary procedure. The average idle time of the room after the end of pulmonary procedure and start of next case or end of shift at 5:00 PM if no next case was 58 ± 53 minutes. In 17/51 (33%) patients the room's idle time was >60 minutes. A total of 52.3% of patients had the wait time >2 days and 11% had it ≥ 6 days, reason in 15/21 (71%) being unavailability of the slot. Most pulmonary procedures were delayed due to spillover of the gastrointestinal and surgical cases into the block time allocated to pulmonary procedures. The most common reason for difficulty encountered in scheduling the pulmonary procedure was slot unavailability. This caused increased procedure waiting time. The strategies to reduce procedure delays and turnaround times, along with improved scheduling methods, may have a favorable impact on the volume of procedures performed in the unit thereby optimizing the existing resources.

  5. "I didn't have anything to decide, I wanted to help my kids" - An interview-based study of consent procedures for sampling human biological material for genetic research in rural Pakistan.

    Kongsholm, Nana Cecilie Halmsted; Lassen, Jesper; Sandøe, Peter

    2018-05-03

    Individual, comprehensive, and written informed consent is broadly considered an ethical obligation in research involving the sampling of human material. In developing countries, however, local conditions, such as widespread illiteracy, low levels of education, and hierarchical social structures complicate compliance with these standards. As a result, researchers may modify the consent process to secure participation. To evaluate the ethical status of such modified consent strategies it is necessary to assess the extent to which local practices accord with the values underlying informed consent. Over a two-week period in April 2014 we conducted semi-structured interviews with researchers from a genetic research institute in rural Pakistan and families who had given blood samples for their research. Interviews with researchers focused on the institute's requirements for consent, and the researchers' strategies for and experiences with obtaining consent in the field. Interviews with donors focused on their motivation for donating samples, their experience of consent and donation, and what factors were central in their decisions to give consent. Researchers often reported modifications to consent procedures suited to the local context, standardly employing oral and elder consent, and tailoring information to the social education level of donor families. Central themes in donors' accounts of their decision to consent were the hope of getting something out of their participation and their remarkably high levels of trust in the researchers. Several donor accounts indicated a degree of confusion about participation and diagnosis, resulting in misconceived expectations of therapeutic benefits. We argue that while building and maintaining trusting relationships in research is important - not least in developing countries - strategies that serve this endeavor should be supplemented with efforts to ensure proper provision and understanding of relevant information

    In the frame of the reported project, together with the programme partners, optimization of service relevant properties as well as modification of manufacturing procedures for the forged alloy Nimonic 101 were achieved. These results are directly implementable into serial production and cause improved service reliability and economic benefit. For the forged alloy Udimet 720 materials data were generated in accordance with the programme plan. The final evaluation for this alloy will be performed by the project partner Siemens-KWU. The qualification of fine-grained investment cast blades of IN 792 for large rear=stage blading is not yet fully completed. Three major questions are lacking final answers: - Does a stress rupture strength advantage exist over the forged alloy Udimet 720/coarse/grained? - Can a high cycle fatigue strength as high as that for Udimet 720/coarse-grained be met reproducibly? - Does the investment cast blades offer a cost advantage over the forged ones - technical qualification assumed? The programme helped significantly in preparing the right answers to these questions. (orig.)

  8. A comparative analysis of online education resources for patients undergoing endoscopic transsphenoidal surgery.

    Fahey, Natalie; Patel, Vimal; Rosseau, Gail

    2014-12-01

    Endoscopic transsphenoidal surgery has become the most commonly performed surgical procedure for pituitary tumor removal. As such, there are many patient-oriented educational materials on the technique available online for members of the public who desire to learn more about the surgery. It has been recommended that educational resources be written to the national average reading level, which in the United States is between sixth and seventh grade. This study assesses the reading level of the educational materials currently available online for endoscopic transsphenoidal surgery and determines whether these resources are written at a suitable comprehension level for most readers. Sixteen patient educational resources describing endoscopic transsphenoidal surgery were identified online and assessed using 4 standard readability assessments. Patient educational resources written for endoscopic transsphenoidal surgery are written far above the recommended reading level of sixth grade. The online educational resources written for patients about endoscopic transsphenoidal surgery are above the recommended reading level for patient education materials. Further revisions to simplify these resources on endoscopic transsphenoidal surgery are needed to ensure that most patients can comprehend this important material and make informed decisions about their health care.

    2015-02-01

    Full Text Available The presented scientific, theoretical and practical aspects of the topic are considered an important prerequisite for understanding the causes and results of the mass use of the deportation repressive tool in the intensive consolidation of Stalin’s totalitarian regime in “class hostile environment” and the consequences of such a policy for the western region development, particularly at modern stage, including the Ukrainian political nation-building and the independent Ukrainian state, which is now experiencing challenges and threats that are rooted in the totalitarian past.Stalinism, as a particular political regime, was established in the western regions of Ukraine at the final stages of World War II and can be defined as a kind of left extremist totalitarianism.The main components of the efficiency of the Stalinist totalitarian regime based on the mass use of political violence and terror through the branched structure of repressive secret police. Functions of the NKVS, NKVD, prosecutors, and courts followed the strategic objectives of Stalin’s totalitarian regime in a hostile social and national environment in Western Ukraine in the complex military and political conditions of the final phase of World War II. Effective and timely implementation of policy priorities of Stalinism in the region allowed to create an appropriate institutional and procedural system, which was based on the large-scale use of political violence and employed such characteristic tools as terror, repression, deportation.

  10. The cellulose resource matrix.

    Keijsers, Edwin R P; Yılmaz, Gülden; van Dam, Jan E G

    2013-03-01

    The emerging biobased economy is causing shifts from mineral fossil oil based resources towards renewable resources. Because of market mechanisms, current and new industries utilising renewable commodities, will attempt to secure their supply of resources. Cellulose is among these commodities, where large scale competition can be expected and already is observed for the traditional industries such as the paper industry. Cellulose and lignocellulosic raw materials (like wood and non-wood fibre crops) are being utilised in many industrial sectors. Due to the initiated transition towards biobased economy, these raw materials are intensively investigated also for new applications such as 2nd generation biofuels and 'green' chemicals and materials production (Clark, 2007; Lange, 2007; Petrus & Noordermeer, 2006; Ragauskas et al., 2006; Regalbuto, 2009). As lignocellulosic raw materials are available in variable quantities and qualities, unnecessary competition can be avoided via the choice of suitable raw materials for a target application. For example, utilisation of cellulose as carbohydrate source for ethanol production (Kabir Kazi et al., 2010) avoids the discussed competition with easier digestible carbohydrates (sugars, starch) deprived from the food supply chain. Also for cellulose use as a biopolymer several different competing markets can be distinguished. It is clear that these applications and markets will be influenced by large volume shifts. The world will have to reckon with the increase of competition and feedstock shortage (land use/biodiversity) (van Dam, de Klerk-Engels, Struik, & Rabbinge, 2005). It is of interest - in the context of sustainable development of the bioeconomy - to categorize the already available and emerging lignocellulosic resources in a matrix structure. When composing such "cellulose resource matrix" attention should be given to the quality aspects as well as to the available quantities and practical possibilities of processing the

  17. Safeguards resource management

    Strait, R.S.

    1986-01-01

    Protecting nuclear materials is a challenging problem for facility managers. To counter the broad spectrum of potential threats, facility managers rely on diverse safeguards measures, including elements of physical protection, material control and accountability, and human reliability programs. Deciding how to upgrade safeguards systems involves difficult tradeoffs between increased protection and the costs and operational impact of protection measures. Effective allocation of safeguards and security resources requires a prioritization of systems upgrades based on a relative measure of upgrade benefits to upgrade costs. Analytical tools are needed to help safeguards managers measure the relative benefits and cost and allocate their limited resources to achieve balanced, cost-effective protection against the full spectrum of threats. This paper presents a conceptual approach and quantitative model that have been developed by Lawrence Livermore National Laboratory to aid safeguards managers

  2. Algae Resources

    None

    2016-06-01

    Algae are highly efficient at producing biomass, and they can be found all over the planet. Many use sunlight and nutrients to create biomass, which contain key components—including lipids, proteins, and carbohydrates— that can be converted and upgraded to a variety of biofuels and products. A functional algal biofuels production system requires resources such as suitable land and climate, sustainable management of water resources, a supplemental carbon dioxide (CO2) supply, and other nutrients (e.g., nitrogen and phosphorus). Algae can be an attractive feedstock for many locations in the United States because their diversity allows for highpotential biomass yields in a variety of climates and environments. Depending on the strain, algae can grow by using fresh, saline, or brackish water from surface water sources, groundwater, or seawater. Additionally, they can grow in water from second-use sources such as treated industrial wastewater; municipal, agricultural, or aquaculture wastewater; or produced water generated from oil and gas drilling operations.

  3. Uranium resources

    1976-01-01

    This is a press release issued by the OECD on 9th March 1976. It is stated that the steep increases in demand for uranium foreseen in and beyond the 1980's, with doubling times of the order of six to seven years, will inevitably create formidable problems for the industry. Further substantial efforts will be needed in prospecting for new uranium reserves. Information is given in tabular or graphical form on the following: reasonably assured resources, country by country; uranium production capacities, country by country; world nuclear power growth; world annual uranium requirements; world annual separative requirements; world annual light water reactor fuel reprocessing requirements; distribution of reactor types (LWR, SGHWR, AGR, HWR, HJR, GG, FBR); and world fuel cycle capital requirements. The information is based on the latest report on Uranium Resources Production and Demand, jointly issued by the OECD's Nuclear Energy Agency (NEA) and the International Atomic Energy Agency. (U.K.)

  4. Water resources

    2002-01-01

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on water resources describes how climate change will affect the supply of water in Canada. Water is one of Canada's greatest resources, which contributes about $7.5 to 23 billion per year to the Canadian economy. The decisions taken to adapt to climate change within the water resources sector will have profound implications in many other areas such as agriculture, human health, transportation and industry. The water related problems include water quality issues that relate to water shortages from droughts, or excesses from floods. The Intergovernmental Panel on Climate Change forecasts an increase in global average surface air temperatures of 1.4 to 5.8 degrees C by 2100. Such a change would impact the hydrological cycle, affecting runoff, evaporation patterns, and the amount of water stored in glaciers, lakes, wetlands and groundwater. The uncertainty as to the magnitude of these changes is due to the difficulty that climate models have in projecting future changes in regional precipitation patterns and extreme events. This chapter presents potential impacts of climate change on water resources in the Yukon, British Columbia, the Prairies, the Great Lakes basin, the Atlantic provinces, and the Arctic and Subarctic. The associated concerns for each region were highlighted. Adaptation research has focused on the impacts of supply and demand, and on options to adapt to these impacts. 60 refs., 2 tabs., 1 fig

  6. Waste minimization assessment procedure

    Kellythorne, L.L.

    1993-01-01

    Perry Nuclear Power Plant began developing a waste minimization plan early in 1991. In March of 1991 the plan was documented following a similar format to that described in the EPA Waste Minimization Opportunity Assessment Manual. Initial implementation involved obtaining management's commitment to support a waste minimization effort. The primary assessment goal was to identify all hazardous waste streams and to evaluate those streams for minimization opportunities. As implementation of the plan proceeded, non-hazardous waste streams routinely generated in large volumes were also evaluated for minimization opportunities. The next step included collection of process and facility data which would be useful in helping the facility accomplish its assessment goals. This paper describes the resources that were used and which were most valuable in identifying both the hazardous and non-hazardous waste streams that existed on site. For each material identified as a waste stream, additional information regarding the materials use, manufacturer, EPA hazardous waste number and DOT hazard class was also gathered. Once waste streams were evaluated for potential source reduction, recycling, re-use, re-sale, or burning for heat recovery, with disposal as the last viable alternative

  8. Material and energy productivity.

    Steinberger, Julia K; Krausmann, Fridolin

    2011-02-15

    Resource productivity, measured as GDP output per resource input, is a widespread sustainability indicator combining economic and environmental information. Resource productivity is ubiquitous, from the IPAT identity to the analysis of dematerialization trends and policy goals. High resource productivity is interpreted as the sign of a resource-efficient, and hence more sustainable, economy. Its inverse, resource intensity (resource per GDP) has the reverse behavior, with higher values indicating environmentally inefficient economies. In this study, we investigate the global systematic relationship between material, energy and carbon productivities, and economic activity. We demonstrate that different types of materials and energy exhibit fundamentally different behaviors, depending on their international income elasticities of consumption. Biomass is completely inelastic, whereas fossil fuels tend to scale proportionally with income. Total materials or energy, as aggregates, have intermediate behavior, depending on the share of fossil fuels and other elastic resources. We show that a small inelastic share is sufficient for the total resource productivity to be significantly correlated with income. Our analysis calls into question the interpretation of resource productivity as a sustainability indicator. We conclude with suggestions for potential alternatives.

    2004-04-01

    The maintenance of operating procedures in a NPP is a tedious and complicated task. Through the whole life cycle of the procedures they will be dynamic, 'living' documents. Several aspects of the procedure must be considered in a revision process. Pertinent details and attributes of the procedure must be checked. An organizational structure must be created and responsibilities allotted for drafting, revising, reviewing and publishing procedures. Available powerful computer technology provides solutions within document management and computerisation of procedures. These solutions can also support the maintenance of procedures. Not all parts of the procedure life cycle are equally amenable to computerized support. This report looks at the procedure life cycle in todays NPPs and discusses the possibilities associated with introduction of computer technology to assist the maintenance of procedures. (Author)

  14. Energy and other resources

    Rosenqvist, I.Th.

    It is pointed out that inorganic mineral raw materials, usually called ores, do not form a separate geological class, with a strictly defined limit in quantity. The raw materials are in fact present in continuously variable concentrations and amounts with differing geographical distribution. It is only the richest occurrences which are regarded as resources and exploited. The cone concept of available material is presented, where the amount of material available increases as the work invested is increased, but the profitable ore is represented only by the apex of the cone. In applying this idea to fossil fuels the concept must be modified to a 'pear', since the energy invested in retrieving the fuel must not exceed the energy content of the fuel. Renewable energy sources are also discussed, and it is pointed out that geothermal energy should not be regarded as renewable. It is pointed out, too, that, unless breeder reactors are introduced, the fossil fuel resources will give more energy than uranium, and probably cheaper. (JIW)Ψ

    2010-08-01

    In the current concept of repository for radioactive waste disposal, compacted bentonite as well as bentonite based material will be used as an engineered barrier mainly for inhibiting migration of radioactive nuclides. In most cases, properties of bentonite, such as low permeability etc., are obtained by laboratory tests. However, results of laboratory tests of bentonite often vary considerably even if index parameter, such as effective clay density, is constant. One of the causes of the variability is considered to be lack of standardized method of laboratory test for bentonite. Thus standardization of laboratory test methods for bentonite is needed. So, investigation for establishing standardized laboratory test method of bentonite is conducted based on the results of survey on current status of laboratory test method for bentonite. In particular, the literature survey as well as laboratory tests were conducted to find factors affecting the results of laboratory tests for bentonite and to estimate their degree of influence. The following conclusions are obtained through this study. (1) Hydraulic conductivity test. According to the results of literature survey, it is revealed that constant pressure permeability test and consolidation test are currently used for measuring hydraulic conductivity of bentonite and that (a) hydraulic gradient, (b) local seepage flow between lateral surface of the specimen and lateral wall of the container, (c) water pressure which is applied to the specimen, (d) degree of saturation and (e) size of the specimen possibly affect the results of the constant pressure permeability test, while (f) friction between lateral surface of the specimen and lateral wall of the container accompanied by deformation of the specimen, (g) consolidation pressure together with factors (d), (e) affect the results of the consolidation test. Literature which describes that factors (a), (b) and (e) affect the results of the constant pressure permeability test

    In this report the relation between exposure and absorbed radiation dose in various materials is represented, on the base of recent data. With the help of this a calibration procedure for thermoluminescent materials, adapted to the IRI radiation standard is still the exposure in rontgen. In switching to the air kerma standard the calibration procedure will have to be adapted. (author). 6 refs.; 4 tabs

  7. Procedures for permission of installation of nuclear power stations

    Narita, Yoriaki

    1980-01-01

    The locations of atomic power stations are first selected by electric power enterprises in consultation with the Ministry of International Trade and Industry or under the guidance of authorities concerned. The surveys of the climate, topography, water and plants in the planned sites and the influences of nuclear power generation to the surrounding areas are made by the enterprisers under the administrative guidance of the MITI. Secondly, the basic project shall be submitted to and decided by the Power Resource Development Council headed by the Prime Minister (Article 10, the Power Resource Development Law). The Council shall, if necessary, call for the attendance of the governors of prefectures concerned and hear their opinions (Article 11, the Law). As the third and most complicated phase, various procedures include; (a) permission of the changes of electrical facilities under the Electricity Enterprises Act; (b) authorization of the installation of reactors under the Nuclear Reactor Regulation Law; (c) permission or authorization under other regulations including the Agricultural Land Act, etc.; (d) additional procedures related to the indemnification to fishery and so forth. Finally the reactors are to be operated after receiving the certificates of the Minister of ITI on the inspections of construction works, nuclear fuel materials used for the reactors and welding processes of reactor containment vessels, boilers, turbines, etc. (Okada, K.)

    This paper provides additional data on a sewage sludge amended soil certified reference material, CRM 483, which was certified in 1997 for its EDTA and acetic acid extractable contents of some trace metals, following standardised extraction procedures. The additional work aimed to test the long-term stability of the material and the applicability of an improved version of the BCR three-step sequential extraction procedure on the sewage sludge amended soil (CRM 483). The paper demonstrates the CRM 483 long-term stability for EDTA and acetic acid extractable contents of Cd, Cr, Cu, Ni, Pb and Zn and gives the results (obtained in the framework of an interlaboratory study) for the extractable contents of the same elements in the CRM 483, following the BCR three-step sequential extraction scheme. The aqua regia extractable contents following the ISO 11466 Standard are also given. The data are given as indicative (not certified) values.

    An online data driven computerized procedures system that guides an operator through a complex process facility's operating procedures. The system monitors plant data, processes the data and then, based upon this processing, presents the status of the current procedure step and/or substep to the operator. The system supports multiple users and a single procedure definition supports several interface formats that can be tailored to the individual user. Layered security controls access privileges and revisions are version controlled. The procedures run on a server that is platform independent of the user workstations that the server interfaces with and the user interface supports diverse procedural views.

  10. Determinants of Critical Infrastructure Resources

    2017-12-01

    Full Text Available This article is devoted to the issue of how resources are interpreted in the form of technology reactors that, as a result of unexpected circumstances, turn into pyramidal or avalanche threat dynamics. Counteracting such catastrophic, terrorist, or war situations cannot begin in the face of mass casualties or significant material losses that will require reconstruction and the work of many generations. The decisive factor is the correct long-term operation and management of the economy. The starting point of this article is the concept of resource and structural-functional relationships of resources and all their possible interpretations consistent with the functionalities they play in the human environment, human aggregates, and whole nations. The aim is to draw the reader's attention to the importance (semiotics of qualitative specifications and dynamically changing determinants contained in the material and structural-functional properties of the resources and their channel (information communication.

    Full Text Available Esta pesquisa tem o objetivo de analisar o relacionamento dos recursos da organização quanto ao seu comportamento estratégico na percepção dos gestores das lojas de material de construção. Para tanto, aborda a teoria de recursos, a partir da RBV (Resource-based View, e a tipologia de Miles e Snow (1978, na determinação do comportamento estratégico das organizações. Com a finalidade de atingir o objetivo proposto utilizou-se uma abordagem qualiquantitativa. A pesquisa qualitativa foi exploratória, utilizando focus group e a quantitativa descritiva, a partir de uma survey. Os resultados, quanto ao comportamento estratégico, indicam que 34,3% das empresas são defensoras, 27,1% são reativas, 20,0% são analistas e 18,6% prospectoras. Com relação às hipóteses propostas, inexistência de diferenças nas capacidades segundo os comportamentos estratégicos, nenhuma mostrou significância estatística. Com Respeito à associação mensurada entre o comportamento estratégico e as capacidades, os prospectores são os que possuem a maior correlação positiva, verificada com as capacidades de administração. Já os reativos são os que apresentam a maior correlação negativa, também com as capacidades de administração. Conclui-se que há ausência de ajuste entre comportamentos estratégicos e os recursos e capacidades, o que pode, segundo a RBV, deixar de gerar vantagem competitiva sustentável.This study aims to investigate the relationship between the organization resources and the strategic behavior from construction material stores viewpoint.

    The Water Environment Federation recently issued a special publication, Biomonitoring in the Water Environment. In this paper, the authors highlight the contents of the chapter 3, Biomonitoring Test Procedures, identify current trends in test procedures and introduce the concept of biological criteria (biocriteria). The book chapter (and this paper) focuses on freshwater and marine chronic and acute toxicity tests used in the National Pollutant Discharge Elimination System (NPDES) permits program to identify effluents and receiving waters containing toxic materials in acutely or chronically toxic concentrations. The two major categories of toxicity tests include acute tests and chronic tests. The USEPA chronic tests required in NPDEs permits have been shortened to 7 days by focusing on the most sensitive life-cycle stages; these tests are often referred to as short-term chronic tests. The type of test(s) required depend on NPDES permit requirements, objectives of the test, available resources, requirements of the test organisms, and effluent characteristics such as variability in flow or toxicity. The permit writer will determine the requirements for toxicity test(s) by considering such factors as dilution, effluent variability, and exposure variability. Whether the required test is acute or chronic, the objective of the test is to estimate the safe or no effect concentration which is defined as the concentration which will permit normal propagation of fish and other aquatic life in the receiving waters. In this paper, the authors review the types of toxicity tests, the commonly used test organisms, and the uses of toxicity test data. In addition, they briefly describe research on new methods and the use of biological criteria.

  13. Human factoring administrative procedures

    Grider, D.A.; Sturdivant, M.H.

    1991-01-01

    In nonnuclear business, administrative procedures bring to mind such mundane topics as filing correspondence and scheduling vacation time. In the nuclear industry, on the other hand, administrative procedures play a vital role in assuring the safe operation of a facility. For some time now, industry focus has been on improving technical procedures. Significant efforts are under way to produce technical procedure requires that a validated technical, regulatory, and administrative basis be developed and that the technical process be established for each procedure. Producing usable technical procedures requires that procedure presentation be engineered to the same human factors principles used in control room design. The vital safety role of administrative procedures requires that they be just as sound, just a rigorously formulated, and documented as technical procedures. Procedure programs at the Tennessee Valley Authority and at Boston Edison's Pilgrim Station demonstrate that human factors engineering techniques can be applied effectively to technical procedures. With a few modifications, those same techniques can be used to produce more effective administrative procedures. Efforts are under way at the US Department of Energy Nuclear Weapons Complex and at some utilities (Boston Edison, for instance) to apply human factors engineering to administrative procedures: The techniques being adapted include the following

  14. Mineral resources

    1991-09-01

    This paper reports that to prevent the concentration of control over federal oil and gas resources in a few companies or individuals, Congress has limited the number of acres of oil and gas leases that one party may control in a single state. An exception to this limitation involves lease acreage within the boundaries of development contracts. These contracts permit oil and gas lease operators and pipeline companies to contract with enough lessees to economically justify large-scale drilling operations for the production and transportation of oil and gas, subject to approval by the Secretary of the Interior, who must find that such contracts are in the public interest. Since 1986 Interior has entered into or approved 10 contracts with 12 lease operators for exploration of largely unleased federal lands-ranging from about 180,000 to 3.5 million acres in four western states-and has designated them as developmental contracts. GAO believes that the 10 contracts do not satisfy the legal requirements for development contracts because they are for oil and gas exploration on largely unleased federal lands, rather than for developing existing leases. By designating the 10 contracts as development contracts, Interior has enabled nine of the 12 contract parties to accumulate lease acreage that vastly exceeds the statutory acreage limitation. All nine of the contract parties were major or large independent oil companies. As a result, other parties who wish to participate in developing federal oil and gas resources within the four states may be adversely affected because the parties to Interior's contracts have been able to compete for and obtain lease acreage beyond the statutory acreage limitation. Although Interior believes that the Secretary has the discretion under law to use development contracts in the current manner, in April 1989 it ceased issuing these contracts pending completion of GAO's review

    This report highlights perspectives and options for action in order to promote sustainable land use considering resource of protection and supply with renewable raw materials. Land use within Germany is described as well as the global land use Germany based on its domestic consumption of products from agriculture and forestry. In terms of sustainable development, a long-lasting environmentally sound land use must be enabled which supports the required supply of renewable raw materials for energetic and non-energetic use while not endangering the future food supply of the growing world population. The Wuppertal Institute for Climate, Environment and Energy (WI), together with the Fraunhofer Institute for Environmental, Safety and Energy Technology (UMSICHT) in Oberhausen and the Institute for Energy and Environmental Research Heidelberg (IFEU), have for the first time with this study performed a comprehensive global land use balance for the consumption of food and non-food biomass in Germany, and have calculated in particular those greenhouse gas emissions which result from land use changes. In order not to endanger the climate and resource policy targets of the German government corrective measures for the implementation of policy targets for biomass use are needed. Existing targets for envisaged, enacted and promoted use of energy plants and biofuels should be reviewed. Existing legal biofuel quotas should by no means be increased. Furthermore, the national biofuels target for 2020 of a 12- 15% biofuels share of fuel consumption should be withdrawn, especially as this would send a clear international message. Such a target in the future would only be justifiable if the total amount of fuel consumed would decrease drastically (i.e. by more than half) as compared with today. Thereby the respective amount of biofuels required in the future would also decrease. The bonus for renewable raw materials of the Renewable Energy Sources Act (EEG) should be critically

    2002-01-01

    We present a concept for using procedural techniques to represent media. Procedural methods allow us to represent digital media (2D images, 3D environments etc.) with very little information and to render it photo realistically. Since not all kind of content can be created procedurally, traditional media representations (bitmaps, polygons etc.) must be used as well. We have adopted an object-based media representation where an object can be represented either with a procedure or with its trad...
