  1. 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.

  2. 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. 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. The book collects together recent proposals and innovative optio...

  8. Polymeric materials from renewable resources

    Frollini, Elisabete; Rodrigues, Bruno V. M.; da Silva, Cristina G.; Castro, Daniele O.; Ramires, Elaine C.; de Oliveira, Fernando; Santos, Rachel P. O.

    2016-05-01

    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.

  9. Water reservoir as resource of raw material for ceramic industry

    Irie, M.; Tarhouni, J.

    2015-04-01

    The industries related to the ceramics such as construction bricks, pottery and tile are the important sectors that cover the large part of the working population in Tunisia. The raw materials, clay or silt are excavated from opencast site of limestone clay stratum. The opencast site give the negative impact on landscape and environment, risks of landslide, soil erosion etc. On the other hand, a most serious problem in water resource management, especially in arid land such as Tunisia, is sedimentation in reservoirs. Sediment accumulation in the reservoirs reduces the water storage capacity. The authors proposed the exploitation of the sediment as raw material for the ceramics industries in the previous studies because the sediment in Tunisia is fine silt. In this study, the potential of the water reservoirs in Tunisia as the resource of the raw material for the ceramics industries is estimated from the sedimentation ratio in the water reservoirs.

  12. Materials Synthesis Of Barium Hexa ferrite Used Local Natural Resources

    The magnetic materials of barium hexa ferrites, Ba O.6Fe2O3 successfully synthesized by powder metallurgy method used local natural resources from materials waste of steel fabrication (HSM, CRM), waste of polymer fabrication (LK) as well as iron sands (PBA). These waste as well as iron sands were the main resources of iron oxide, Fe2O3. The barium oxide used in this experiments are from BaCO3 product of Merck, and BaCO4 which is commercially available in the market as barite. Phase identification by x-ray diffraction technique show the synthesized magnetic materials are agreed with the available commercial product, (SUMI). The energy product maximum (BH)max measured by vibrating sample magnetometer (VSM) for the samples used HSM-, CRM- and BaCO3 as basic materials are 1.141 MGOe and 1.136 MGOe while SUMI is 1.142 MGOe. However for the samples made from LK-, PBA- used of BaCO3 or CRM- with barite, the energy product maximum (BH)max are relatively lower than commercial product

  15. Maintenance modeling and optimization integrating human and material resources

    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.

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

    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.

  1. Relative resource abundance explains butterfly biodiversity in island communities

    Yamamoto, Naoaki; Yokoyama, Jun; Kawata, Masakado

    2007-01-01

    Ecologists have long been intrigued by the factors that control the pattern of biodiversity, i.e., the distribution and abundance of species. Previous studies have demonstrated that coexisting species partition their resources and/or that the compositional similarity between communities is determined by environmental factors, lending support to the niche-assembly model. However, no attempt has been made to test whether the relative amount of resources that reflects relative niche space contro...

  8. Oxytocin receptor gene (OXTR) is related to psychological resources

    Saphire-Bernstein, Shimon; Way, Baldwin M.; Kim, Heejung S.; Sherman, David K.; Taylor, Shelley E.

    2011-01-01

    Psychological resources—optimism, mastery, and self-esteem—buffer the deleterious effects of stress and are predictors of neurophysiological and psychological health-related outcomes. These resources have been shown to be highly heritable, yet the genetic basis for this heritability remains unknown. Here, we report a link between the oxytocin receptor (OXTR) SNP rs53576 and psychological resources, such that carriers of the “A” allele have lower levels of optimism, mastery, and self-esteem, r...

  9. Relative consequences of transporting hazardous materials

    The objective of this paper is to discuss methods under study at Transportation Technology Center to develop a perspective on how technical measures of hazard and risk relate to perception of hazards, harm, and risks associated with transporting hazardous materials. This paper is concerned with two major aspects of the relative hazards problem. The first aspect is the analyses of the possible effects associated with exposure to hazardous materials as contained in the following two parts: outlines of possible problems and controversies that could be encountered in the evaluation and comparisons of hazards and risks; and description of the various measures of harm (hazards or dangers) and subsequent comparisons thereof. The second aspect of this paper leads into a presentation of the results of a study which had the following purposes: to develop analytical techniques for a consistent treatment of the phenomenology of the consequences of a release of hazardous materials; to reduce the number of variables in the consequence analyses by development of transportation accident scenarios which have the same meteorological conditions, demography, traffic and population densities, geographical features and other appropriate conditions and to develop consistent methods for presenting the results of studies and analyses that describe the phenomenology and compare hazards. The results of the study are intended to provide a bridge between analytical certainty and perception of the hazards involved. Understanding the differences in perception of hazards resulting from transport of various hazardous materials is fraught with difficulties in isolating the qualitative and quantitative features of the problem. By relating the quantitative impacts of material hazards under identical conditions, it is hoped that the perceived differences in material hazards can be delineated and evaluated

  10. 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. Multifunctional Martian habitat composite material synthesized from in situ resources

    Sen, S.; Carranza, S.; Pillay, S.

    2010-09-01

    The two primary requirements for a Martian habitat structure include effective radiation shielding against the Galactic Cosmic Ray (GCR) environment and sufficient structural and thermal integrity. To significantly reduce the cost associated with transportation of such materials and structures from earth, it is imperative that such building materials should be synthesized primarily from Martian in situ resources. This paper illustrates the feasibility of such an approach. Experimental results are discussed to demonstrate the synthesis of polyethylene (PE) from a simulated Martian atmosphere and the fabrication of a composite material using simulated Martian regolith with PE as the binding material. The radiation shielding effectiveness of the proposed composites is analyzed using results from radiation transport codes and exposure of the samples to high-energy beams that serve as a terrestrial proxy for the GCR environment. Mechanical and ballistic impact resistance properties of the proposed composite as a function of composition, processing parameters, and thermal variations are also discussed to evaluate the multifunctionality of such in situ synthesized composite materials.

  13. Radiation effects on pharmaceuticals and related materials

    Radiation sterilization is the method of choice for many medical supplies and devices. However, because of the ionizing nature of gamma radiation, one must consider the effect of such radiation on the physical and chemical properties and on the biological behaviour of pharmaceutical and related materials before the feasibility of radiation sterilization for such products is established. The results of such feasibility studies can lead to an appropriate decision on the suitability of radiation sterilization for a particular pharmaceutical. (author)

  14. Adaptive differentiation of traits related to resource use in a desert annual along a resource gradient.

    Brouillette, Larry C; Mason, Chase M; Shirk, Rebecca Y; Donovan, Lisa A

    2014-03-01

    • Plant resource-use traits are generally hypothesized to be adaptively differentiated for populations distributed along resource gradients. Although nutrient limitations are expected to select for resource-conservative strategies, water limitations may select for either resource-conservative or -acquisitive strategies. We test whether population differentiation reflects local adaptation for traits associated with resource-use strategies in a desert annual (Helianthus anomalus) distributed along a gradient of positively covarying water and nutrient availability. • We compared quantitative trait variation (Q(ST)) with neutral genetic differentiation (F(ST)), in a common garden glasshouse study, for leaf economics spectrum (LES) and related traits: photosynthesis (A(mass), A(area)), leaf nitrogen (N(mass), N(area)), leaf lifetime (LL), leaf mass per area (LMA), leaf water content (LWC), water-use efficiency (WUE, estimated as δ(13)C) and days to first flower (DFF). • Q(ST)-F(ST) differences support adaptive differentiation for Amass , N(mass), N(area), LWC and DFF. The trait combinations associated with drier and lower fertility sites represent correlated trait evolution consistent with the more resource-acquisitive end of the LES. There was no evidence for adaptive differentiation for A(area), LMA and WUE. • These results demonstrate that hot dry environments can selectively favor correlated evolution of traits contributing to a resource-acquisitive and earlier reproduction 'escape' strategy, despite lower fertility.

  19. Relative prices and investment: an essay on resource allocation

    Keith Griffin

    2005-01-01

    In this essay the mainstream story about how resources are allocated in a market economy is challenged. The conventional view is that a change in relative prices leads to a change in the composition of output as a result of a reallocation of the stock of primary factors of production (land, labor and capital). No investment is required. This is possible, however, only if the primary factors of production are homogeneous and hence highly mobile. If land, labor and capital are heterogeneous and...

  20. Understanding and mitigating HIV-related resource-based stigma in the era of antiretroviral therapy.

    Holmes, Kathleen; Winskell, Kate

    2013-01-01

    The perception in low-resource settings that investment of resources in people living with HIV (PLHIV) is wasted because AIDS is both an incurable and deadly disease is known as resource-based stigma. In this paper, we draw on in-depth interviews (IDI), focus group discussions (FGD), and key informant interviews (KII) with 77 HIV-positive microfinance participants and nongovernmental organization leaders to examine resource-based stigma in the context of increased access to antiretroviral therapy (ART) at an individual, household, and community level in Côte d'Ivoire. The purpose of this exploratory paper is to examine: (1) resource-based stigmatization in the era of ART and (2) the relationship among microfinance, a poverty-reduction intervention, and HIV stigmatization. The frequency with which resource-based stigma was discussed by respondents suggests that it is an important component of HIV-related stigma in this setting. It affected PLHIV's access to material as well as social resources, leading to economic discrimination and social devaluation. Participation in village savings and loans groups, however, mitigated resource-based HIV stigma, suggesting that in the era of increased access to antiretroviral therapy, economic programs should be considered as one possible HIV stigma-reduction intervention.

  1. Advanced Functional Materials for Energy Related Applications

    Sasan, Koroush

    The current global heavy dependency on fossil fuels gives rise to two critical problems: I) fossil fuels will be depleted in the near future; II) the release of green house gas CO2 generated by the combustion of fossil fuels contributes to global warming. To potentially address both problems, this dissertation documents three primary areas of investigation related to the development of alternative energy sources: electrocatalysts for fuel cells, photocatalysts for hydrogen generation, and photoreduction catalysts for converting CO2 to CH4. Fuel cells could be a promising source of alternative energy. Decreasing the cost and improving the durability and power density of Pt/C as a catalyst for reducing oxygen are major challenges for developing fuel cells. To address these concerns, we have synthesized a Nitrogen-Sulfur-Iron-doped porous carbon material. Our results indicate that the synthesized catalyst exhibits not only higher current density and stability but also higher tolerance to crossover chemicals than the commercial Pt/C catalyst. More importantly, the synthetic method is simple and inexpensive. Using photocatalysts and solar energy is another potential alternative solution for energy demand. We have synthesized a new biomimetic heterogeneous photocatalyst through the incorporation of homogeneous complex 1 [(i-SCH 2)2NC(O)C5H4N]-Fe2(CO) 6] into the highly robust zirconium-porphyrin based metal-organic framework (ZrPF). As photosensitizer ZrPF absorbs the visible light and produces photoexcited electrons that can be transferred through axial covalent bond to di-nuclear complex 1 for hydrogen generation. Additionally, we have studied the photoreduction of CO2 to CH4 using self-doped TiO2 (Ti+3@TiO 2) as photocatalytic materials. The incorporation of Ti3+ into TiO2 structures narrows the band gap, leading to significantly increased photocatalytic activity for the reduction of CO2 into renewable hydrocarbon fuel in the presence of water vapor under visible

    Tang, M; Norquist, P; Barton, N; Durrenberger, K; Florando, J; Attia, A

    2010-12-13

    MIDAS is aimed to be an easy-to-use and comprehensive common source for material properties including both experimental data and models and their parameters. At LLNL, we will develop MIDAS to be the central repository for material strength related data and models with the long-term goal to encompass other material properties. MIDAS will allow the users to upload experimental data and updated models, to view and read materials data and references, to manipulate models and their parameters, and to serve as the central location for the application codes to access the continuously growing model source codes. MIDAS contains a suite of interoperable tools and utilizes components already existing at LLNL: MSD (material strength database), MatProp (database of materials properties files), and MSlib (library of material model source codes). MIDAS requires significant development of the computer science framework for the interfaces between different components. We present the current status of MIDAS and its future development in this paper.

  3. Facilitating NCAR Data Discovery by Connecting Related Resources

    Rosati, A.

    2012-12-01

    Linking datasets, creators, and users by employing the proper standards helps to increase the impact of funded research. In order for users to find a dataset, it must first be named. Data citations play the important role of giving datasets a persistent presence by assigning a formal "name" and location. This project focuses on the next step of the "name-find-use" sequence: enhancing discoverability of NCAR data by connecting related resources on the web. By examining metadata schemas that document datasets, I examined how Semantic Web approaches can help to ensure the widest possible range of data users. The focus was to move from search engine optimization (SEO) to information connectivity. Two main markup types are very visible in the Semantic Web and applicable to scientific dataset discovery: The Open Archives Initiative-Object Reuse and Exchange (OAI-ORE - www.openarchives.org) and Microdata (HTML5 and www.schema.org). My project creates pilot aggregations of related resources using both markup types for three case studies: The North American Regional Climate Change Assessment Program (NARCCAP) dataset and related publications, the Palmer Drought Severity Index (PSDI) animation and image files from NCAR's Visualization Lab (VisLab), and the multidisciplinary data types and formats from the Advanced Cooperative Arctic Data and Information Service (ACADIS). This project documents the differences between these markups and how each creates connectedness on the web. My recommendations point toward the most efficient and effective markup schema for aggregating resources within the three case studies based on the following assessment criteria: ease of use, current state of support and adoption of technology, integration with typical web tools, available vocabularies and geoinformatic standards, interoperability with current repositories and access portals (e.g. ESG, Java), and relation to data citation tools and methods.

  4. Model Modification and Application on Carrying Capacity of Relative Resources

    2009-01-01

    Based on the retrospection of researches on carry-ing capacity, this article reviewed systematically the research progresses on carrying capacity of relative resources (CCRR).Then the viewpoint was put forward that CCRR is not an ap-propriate method of appraising the regional sustainability, but a sound way to obtain cognition for coordinating spatial loca-tion and flow of population and economy.However, as the most popular computing method of CCRR, the Weighting Linear Sum Model is defective in the random of weight choice and the neglect of matching among different resources.Therefore, this article established the Geometric Model on CCRR based on modifying Weighting Linear Sum Model, which can be used to appraise regions where resources are close matching.Em-ploying the Geometric Model, the article empirically analyzed the population and economic CCRR in Hubei Province from 1978 to 2006.The result indicates that the population in Hubei Province is overloading while the economic carrying capacity is abundant compared to the whole country, and the economic insufficiency restricts the population carrying capacity.In the future, Hubei Province will become one of the core developing zones which are characterized by economic conglomeration.

  17. Molten salts and energy related materials.

    Fray, Derek

    2016-08-15

    Molten salts have been known for centuries and have been used for the extraction of aluminium for over one hundred years and as high temperature fluxes in metal processing. This and other molten salt routes have gradually become more energy efficient and less polluting, but there have been few major breakthroughs. This paper will explore some recent innovations that could lead to substantial reductions in the energy consumed in metal production and in carbon dioxide production. Another way that molten salts can contribute to an energy efficient world is by creating better high temperature fuel cells and novel high temperature batteries, or by acting as the medium that can create novel materials that can find applications in high energy batteries and other energy saving devices, such as capacitors. Carbonate melts can be used to absorb carbon dioxide, which can be converted into C, CO and carbon nanoparticles. Molten salts can also be used to create black silicon that can absorb more sunlight over a wider range of wavelengths. Overall, there are many opportunities to explore for molten salts to play in an efficient, low carbon world. PMID:27276650

  18. 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.)

  19. Making sense of the electronic resource marketplace: trends in health-related electronic resources.

    Blansit, B D; Connor, E

    1999-07-01

    Changes in the practice of medicine and technological developments offer librarians unprecedented opportunities to select and organize electronic resources, use the Web to deliver content throughout the organization, and improve knowledge at the point of need. The confusing array of available products, access routes, and pricing plans makes it difficult to anticipate the needs of users, identify the top resources, budget effectively, make sound collection management decisions, and organize the resources effectively and seamlessly. The electronic resource marketplace requires much vigilance, considerable patience, and continuous evaluation. There are several strategies that librarians can employ to stay ahead of the electronic resource curve, including taking advantage of free trials from publishers; marketing free trials and involving users in evaluating new products; watching and testing products marketed to the clientele; agreeing to beta test new products and services; working with aggregators or republishers; joining vendor advisory boards; benchmarking institutional resources against five to eight competitors; and forming or joining a consortium for group negotiating and purchasing. This article provides a brief snapshot of leading biomedical resources; showcases several libraries that have excelled in identifying, acquiring, and organizing electronic resources; and discusses strategies and trends of potential interest to biomedical librarians, especially those working in hospital settings.

  1. Linking rates of diffusion and consumption in relation to resources.

    Avgar, Tal; Kuefler, Daniel; Fryxell, John M

    2011-08-01

    The functional response is a fundamental model of the relationship between consumer intake rate and resource abundance. The random walk is a fundamental model of animal movement and is well approximated by simple diffusion. Both models are central to our understanding of numerous ecological processes but are rarely linked in ecological theory. To derive a synthetic model, we draw on the common logical premise underlying these models and show how the diffusion and consumption rates of consumers depend on elementary attributes of naturally occurring consumer-resource interactions: the abundance, spatial aggregation, and traveling speed of resources as well as consumer handling time and directional persistence. We show that resource aggregation may lead to increased consumer diffusion and, in the case of mobile resources, reduced consumption rate. Resource-dependent movement patterns have traditionally been attributed to area-restricted search, reflecting adaptive decision making by the consumer. Our synthesis provides a simple alternative hypothesis that such patterns could also arise as a by-product of statistical movement mechanics. PMID:21750382

  7. 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

  8. Evaluation of Structure Influence on Thermal Conductivity of Thermal Insulating Materials from Renewable Resources

    Jolanta VĖJELIENĖ

    2011-07-01

    Full Text Available The development of new thermal insulation materials needs to evaluate properties and structure of raw material, technological factors that make influence on the thermal conductivity of material. One of the most promising raw materials for production of insulation material is straw. The use of natural fibres in insulation is closely linked to the ecological building sector, where selection of materials is based on factors including recyclable, renewable raw materials and low resource production techniques In current work results of research on structure and thermal conductivity of renewable resources for production thermal insulating materials are presented. Due to the high abundance of renewable resources and a good its structure as raw material for thermal insulation materials barley straw, reeds, cattails and bent grass stalks are used. Macro- and micro structure analysis of these substances is performed. Straw bales of these materials are used for determining thermal conductivity. It was found that the macrostructure has the greatest effect on thermal conductivity of materials. Thermal conductivity of material is determined by the formation of a bale due to the large amount of pores among the stalks of the plant, inside the stalk and inside the stalk wall.http://dx.doi.org/10.5755/j01.ms.17.2.494

  15. Fly ash: Perspective resource for geo-polymer materials production

    Kargin, Aleksey; Baev, Vladimir; Mashkin, Nikolay; Uglyanica, Andrey

    2016-01-01

    The present paper presents the information about the chemical and mineralogical composition of the ash and slag and their amounts at the dumps of the thermoelectric plants located in the city of Kemerovo. It is known that about 85% of ash and slag from the thermoelectric plants in Russia are removed by means of the hydraulic sluicing systems and only about 15% - by the systems of pneumatic ash handling. Currently, however, the transition from the "wet" ash removal systems to the "dry" ones is outlined. This process is quite logical since the fly ash has the higher reactivity compared with the hydraulic sluicing ash and therefore it is of the great interest for recycling and use. On the other hand, the recent trend is the increased use of fly ash in the production of geo-polymers due to their availability, workability and the increased life of the final product. The analysis is carried out to check the possibility of using the fly ash from various Kemerovo thermoelectric plants as a raw material for the production of the alkali-activated binder.

  19. Uranium resources and production of nuclear fuel material in the world

    Data are summed up relating to uranium resources, the technology of nuclear fuel manufacture, the prices of U concentrate and the costs of the basic operations of the fuel cycle. Resources are sufficient for the needs of nuclear power production based on LWR's without closing the fuel cycle for at least up to the year 2010; in the subsequent period fuels of higher price categories would have to be used (> or approx. 130 $/kg U). The manufacture of U concentrate after culmination in the years 1979 to 1980 is declining as is its price. Fuel material on an operation scale (15a t/year and more) is now being manufactured in 11 countries, with the US leading followed by Canada and Japan. From the point of view of technology the following methods are interesting: processing complex ores (USSR), the use of wastes from the production of nuclear purity uranium in agriculture (Canada), single-stage reconversion of UF6 to UO2 (the so-called IDR process in the UK), chemical methods of uranium enrichment (France and Japan), etc. Great attention is being devoted to the design and construction of spent fuel reprocessing plants and thus the introduction of the closed fuel cycle which is the only way towards the full utilization of uranium, to the transition to fast reactors and the extended service life of nuclear power way into the next millenium.

  1. The Current State of China's Freshwater Resources and Related Suggestions

    Wu Ruijin

    2001-01-01

    China has many lakes, marshlands and rivers. Due to their uneven geographical distribution and varied degrees of salinity, their exploitable freshwater resources are limited. In the wake of the highspeed growth of national economy in recent years, human infringement upon their natural settings has been increasingly intense, leading to the degeneration of China's lacustrine ecosystems and the degradation of their surrounding environments. Lakes are shrinking and becoming more saline. In arid and semi-arid inland areas, some of them have even disappeared. In addition, lake water pollution and eutrophication in densely populated areas are getting worse, resulting in serious water shortages in some places. Silt deposition in lake basins, water surface shrinkage caused by hectic and irrational reclamation for farmland, the prevalence of flooding and water-logging calamities and ecosystem depletion caused by predatory exploitation of fishery resources, all of these have become restrictive factors in regional sustainable development. The author of this article suggests measures for the protection and sustainable exploitation of limnetic settings in China.

  5. Human resource issues related to an expanding nuclear power programme

    The IAEA Technical Working Group on Training and Qualification of Nuclear Power Plant Personnel recommended that the IAEA develop guidelines on human resource management (including staffing) and training/education programmes for new nuclear power plant (NPP) designs. This recommendation was made in recognition that these future NPPs may have significantly different needs in this area compared to operating plants, and if so, NPP operating organizations should integrate these needs into their planning for future NPP projects. This report is primarily intended for use by NPP operating organizations that already have units in operation and that are considering adding to their fleet. Therefore, the addition of both new and current designs are addressed in this report. However, it should also be of value to those organizations that are considering the initial implementation of nuclear power, as well as decision makers in government, and in other nuclear industry organizations

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

    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, CO2 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 CO2 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, CO2 and methane. • We discussed on waste heat and CO2 emission by human breathing

  8. EU-Russia Relations Regarding Water Resources in Central Asia

    Anastasia Likhacheva

    2014-05-01

    Full Text Available In Central Asia, the water deficit and water-energy problem have been one of among the most acute and conflict-ridden challenges for the sustainable development of the region and for regional security. Key trade and investment partners, including Russia and the European Union, could play a considerable role in influencing this issue, due to the long-lasting status quo, the inability to find a solution through intra-regional dialogue and the region’s rising dependence on foreign trade. Indeed, water-related interactions between Russia and the EU have been developing in a complementary manner. The EU possesses new technologies and its members have access to long-term capital markets, while Russia carries influence through providing security, regulating migration and holding a favourable political position for offering mediation services to the republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. This article examines EU-Russia relations regarding water issues in Central Asia over the medium term. By analyzing cooperative and non-cooperative strategies used by the major stakeholders in the water conflict (the five republics and the third parties of Russia and the EU, it confirms the continuous complementary character of EU and Russian activities in this context. Russia will take responsibility for moderating the principal questions (as with the construction of big dams such as Rogunor Kambarata, as they relate to the provision of security guarantees. The EU will act through providing support for water companies from small and medium-sized enterprises, and promoting the European Water Initiative principles and by developing its investment policy. The intersection of interests is possible when if Russia will attracts an independent arbiter, such as an actor available to provide guarantees related to the values of professional objectivism, human rights support and environment protection. These issues inevitably arise with

    1977-01-01

    Eighteen samples of aircraft seat materials were evaluated for relative toxicity using the USF/NASA toxicity screening test method. Nine samples were upholstery fabrics and nine samples were cushioning foams. Under these particular conditions of test, the aromatic phenolic and aromatic polyamide fabrics exhibited less toxicity than the samples of wool and wool/nylon fabrics, and the samples of neoprene foams exhibited less toxicity than the samples of polyurethane foams. These relative toxicity rankings were obtained using both apparent lethal concentration for 50 percent of the test animals (ALC50), and time to death (Td) at a fixed weight of material.

  19. Food and agriculture in relation to energy, environment and resources

    Current trends in cultivated land, world population, agricultural practices food and energy are briefly reviewed. The rise in energy input/food energy output ratios with modernization is indicated. Nutritional needs, and trends in food and energy demand per capita are also indicated. Some emerging constraints in relation to soil fertility and agrochemical usage are identified. A growing pressure on land for ''energy and chemical farming'' is foreseen. Losses of native and added soil nitrogen, comparable with total industrial fertilizer nitrogen fixation, seem unavoidable for two decades at least. This consideration of trends and their interactions suggests the need for more effective interdisciplinary study, longer-term planning and international cooperation. (author)

  3. Cultural Resource Investigations for the Resumption of Transient Testing of Nuclear Fuels and Material at the Idaho National Laboratory

    Brenda R. Pace; Julie B. Williams

    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

  6. APPLICATION OF EMF SHF IN PROCESSING TECHNOLOGIES FOR VEGETABLE MATERIAL AND SECONDARY RESOURCES

    Lisovoy V. V.

    2016-04-01

    Full Text Available The article analyzes the proprietary methods of processing of vegetable raw materials and secondary resources with the use of electromagnetic fields (EMF SHF. Analysis of the database of Rospatent World Intellectual Property Organization led to the conclusion that EMF SHF used in the processing of vegetable raw materials in the following processes: drying, reduction of microbial contamination (decontamination, juice production and extraction. It is established that the application of EMF SHF is the most effective in preparation for drying a plant raw material and not directly at the stage of drying, thus reducing the loss of heat-labile active compound in the drying process, and therefore obtain a finished product of higher quality and nutritional value. The patented methods of extraction of vegetable raw materials extraction process performed that extracting directly EMF SHF does not allow pre-hold inactivate enzymes contained in the raw material and lead to undesirable oxidative and hydrolytic processes, and hence a decrease in the yield of extractable substances in the extract and the deterioration of its quality . Therefore, as in the case of drying plant material, EMF SHF can be more effectively used in preparation for an extraction process. Based on the analysis, it was concluded that the relevance of developments in the field of technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage of their preparation for such basic processes - drying, extraction, etc.

  8. Quantum capacitance in monolayers of silicene and related buckled materials

    Nawaz, S.; Tahir, M.

    2016-02-01

    Silicene and related buckled materials are distinct from both the conventional two dimensional electron gas and the famous graphene due to strong spin orbit coupling and the buckled structure. These materials have potential to overcome limitations encountered for graphene, in particular the zero band gap and weak spin orbit coupling. We present a theoretical realization of quantum capacitance which has advantages over the scattering problems of traditional transport measurements. We derive and discuss quantum capacitance as a function of the Fermi energy and temperature taking into account electron-hole puddles through a Gaussian broadening distribution. Our predicted results are very exciting and pave the way for future spintronic and valleytronic devices.

    Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of...... efficiencies. Overall, the waste refinery provided global warming (GW) savings comparable with efficient incineration, MBT, and bioreactor landfilling technologies. The main environmental benefits from waste refining were a potential for improved phosphorus recovery (about 85%) and increased electricity...... production (by 15-40% compared with incineration), albeit at the potential expense of additional toxic emissions to soil. Society's need for the outputs from waste, i.e., energy products (electricity vs transport fuels) and resources (e.g., phosphorus), and the available waste composition were found decisive...

  11. Oral health-related resources - a salutogenic perspective on Swedish 19-year-olds.

    Lindmark, U; Abrahamsson, K H

    2015-02-01

    The aim was to explore health-oriented resources among 19-year-olds and, specifically, how these resources interact with oral health-related attitudes and behaviour. To represent individuals with various psychosocial environments and socioeconomic areas, the participants were selected from different geographical locations of the Public Dental Service clinics in the county of Jönköping, Sweden. A structured questionnaire was distributed, including the instrument 'sense of coherence', for description of the study group, followed by a semi-structured thematized interview. The qualitative method used for sampling and analyses was grounded theory. Data sampling and analysis were performed in parallel procedures and ended up in a sample of ten informants (five women). In the analysis of interview data, a core category was identified, 'Resources of Wealth and Balance in Life - a Foundation for Healthy Choices', describing the central meaning of the informants' perceptions of resources with an essential beneficial impact on oral health. The core category was built on five themes, which in turn had various subthemes, describing different dimensions of resources interacting with beneficial oral health-related attitudes and behaviour: 'Security-building Resources and Support', 'Driving force and Motivation', 'Maturity and Insight', 'Health Awareness' and 'Environmental influences.' The results elucidate personal and environmental health-oriented resources with influence on oral health-related attitudes and behaviours of young individuals. Such beneficial recourses should be recognized by dental personnel to promote oral health. PMID:25041137

  14. Neutron imaging methods for the investigation of energy related materials

    After a short explanation of the state-of-the-art in the field of neutron imaging, we compare X-ray scanning and neutron-imaging. Both imaging techniques are similar and complement each other well with advantages and drawbacks, individually different for each individual material. The interaction of X-rays is mainly with the electrons in the atomic shell, while neutrons deal mainly with the atomic nuclei. This gives the clear contrast differences in the transmission imaging: for X-rays the rule holds: the higher the atomic mass, the higher the contrast. This is not at all valid for the neutrons, where already some light elements (H, Li, B) interacts strongly while some heavy elements are transparent (Pb, Bi, U, Au). We give some examples how energy related materials can be studied successfully by neutron imaging. These materials are involved in fuel cell studies, battery research approaches, the storage of hydrogen, and in nuclear fuels. It is possible to derive the degree of enrichment of fresh fuel from neutron radiography data directly and with good accuracy and non-invasively. Neutron imaging technique allows also the study of neutron-caused embrittlement of fuel cladding Zr alloys. The high contrast for light isotopes like H-1, Li-6 or B-10 are used to trace low amounts of material even within compact sealing of metals which are relatively transparent for neutrons at the same time

  15. The EU Raw Materials Initiative and effects upon resource-based development: Lessons from Africa

    Küblböck, Karin

    2013-01-01

    In the context of a global surge in demand for commodities, increasing competition and rising prices, several industrialized countries including the European Union have adopted strategies to secure access to raw materials. At the same time, in resource-rich developing countries the debate has intensified about too little benefits from their mineral wealth and about a necessary greater contribution of the mining sector to economic transformation. Through Article 208 of the Lisbon Treaty the EU...

  16. Layered intercalated functional materials based on efficient utilization of magnesium resources in China

    David; G; EVANS

    2010-01-01

    Mg-based layered intercalated functional materials of the layered double hydroxide type are a significant class of magnesium compounds.Based on long-term studies of these materials in the State Key Laboratory of Chemical Resource Engineering in Beijing University of Chemical Technology,two principles of "using the intended application of a material as a guide to its structure design and synthesis process" and "the design of controlled intercalation processes in the light of future production processing requirements" have been developed.To achieve these objectives,the composition of the host layers and guest interlayer anions was tailored at the microlevel,while the mesostructure and macrostructure were controlled to fabricate different kinds of Mg-based layered intercalated functional materials.These materials have diverse applications in key areas such as catalysis,the environment,and construction,and as polymer additives.Therefore,China’s magnesium resources may be utilized more efficiently for the benefit of society.

  17. Unpacking Social Media’s Role in Resource Provision: Variations across Relational and Communicative Properties

    Jessica Vitak

    2014-10-01

    Full Text Available New information and communication technologies (ICTs challenge existing beliefs regarding the exchange of social resources within a network. The present study examines individuals’ perceived access to social, emotional, and instrumental resources by analyzing relational and Facebook-specific characteristics of dyadic relationships. Results suggest that the social and technical affordances of the site—including visibility of content and connections, as well as streamlined processes for interacting with a large audience—may augment existing perceptions of resource access for some ties while providing a major (or sole outlet to interact and exchange resources with others. Specifically, weaker ties appear to benefit more than strong ties from engagement in directed communication and relationship maintenance strategies, while additional variations were observed across relationship category, dyad composition, and geographic proximity. In summary, these findings provide new evidence for how positive relational gains may be derived from site use.

  18. Access to strategic resources through the relational network of the contractor and innovation of Tunisian SMEs

    Adel Ghodbane

    2016-04-01

    Full Text Available Our paper is devoted to analyze the mediating effects of the access to strategic resources between the relational network of contractors and innovation in the specific case of Tunisian SMEs. The originality of this approach lies in the effort to show that the detention of a relational network is not synonymous with real access to strategic resources and the realization of benefits in terms of innovation. This finding is particularly important for SMEs which lack the means to profit from their own relational fabrics.

    Suomalainen E.

    2012-01-01

    Sustainable resource use is one of the most important environmental issues of our times. It is closely related to discussions on the 'peaking' of various natural resources serving as energy sources, agricultural nutrients, or metals indispensable in high-technology applications. Although the peaking theory remains controversial, it is commonly recognized that a more sustainable use of resources would alleviate negative environmental impacts related to resource use. In this thesis, sustainable...

    2012-01-01

    With the help of my article I am discovering hypothesis about the law related to management of natural resources and present environment law & critical analysis of its environment effect. It is my belief that is root of origin of “Law” or origin of “Statutes” in world the main reason was the management of natural resources. On this basis it is necessary to add a new branch – Environment School of Jurisprudence in the branches of Jurisprudence.

  2. Surrounding material effect on measurement of thunderstorm-related neutrons

    Tsuchiya, H

    2014-01-01

    Observations of strong flux of low-energy neutrons were made by $^{3}\\mathrm{He}$ counters during thunderstorms [Gurevich et al (Phys. Rev. Lett. 108, 125001, 2012)]. How the unprecedented enhancements were produced remains elusive. To better elucidate the mechanism, a simulation study of surrounding material impacts on measurement by $^{3}\\mathrm{He}$ counters was performed with GEANT4. It was found that unlike previously thought, a $^3\\mathrm{He}$ counter had a small sensitivity to high-energy gamma rays because of inelastic interaction with its cathode-tube materials (Al or stainless steel). A $^{3}\\mathrm{He}$ counter with the intrinsic small sensitivity, if surrounded by thick materials, would largely detect thunderstorm-related gamma rays rather than those neutrons produced via photonuclear reaction in the atmosphere. On the other hand, the counter, if surrounded by thin materials and located away from a gamma-ray source, would observe neutron signals with little gamma-ray contamination. Compared with t...

  3. Lunar utilization. [materials resources and cislunar transportation considerations for space industrialization

    Waldron, R. D.; Criswell, D. R.

    1982-01-01

    The resources, techniques, and purposes to which lunar materials could be put are discussed, with attention given to transporting lunar materials to cislunar space for the construction of space manufacturing and habitable facilities. A model molecule, demandite, which represents the mole fraction of all materials used in the U.S. in 1967, is used to assess the lunar resources defined during Apollo missions. It is shown that duplication of the same manufacturing, fuel, and life-support systems in space as those on earth would cost several orders of magnitude more if the materials originated on earth than on the moon. The demandite would be sent into cislunar orbit using linear electric motors. Lunar surface concentrations of pyroxenes, olivine, feldspars, ilmenite, basalts, anorthostatic rocks, and breccias are reviewed, noting that carbon in the regolith is solar-wind derived, while in lunar rocks the carbon is indigenous. Lunar mining techniques are envisioned, especially the capacity to move large masses at 1/6 the effort required on the earth.

  5. Minnesota anglers' fisheries-related value orientations and their stewardship of fish resources

    Bruskotter, J.T.; Fulton, D.C.

    2008-01-01

    Research on natural resource-related values and value orientations has grown substantially over the past decade. However, existing studies have focused almost exclusively on value orientations related to wildlife and forests. This article reports data from two mail surveys of Minnesota anglers used to develop scales for measuring fisheries-related value orientations. We report results of regression analyses examining the relationship between anglers' value orientations and norms concerning fisheries stewardship and the use of technological aids to angling. Results indicate 10 items reliably measure three value orientations we termed utilitarianism, dominance, and protectionism. Regression analyses suggest anglers' stewardship norms are influenced by all three value orientation types, while support for the use of technological aids was related with protectionism and utilitarianism, but not dominance. Results suggest anglers' fisheries-related value orientations cannot be adequately captured using single domain scales. Implications for the study of natural resources-related value orientations are discussed. Copyright ?? Taylor & Francis Group, LLC.

  6. Material resources, energy, and nutrient recovery from waste: are waste refineries the solution for the future?

    Tonini, Davide; Martinez-Sanchez, Veronica; Astrup, Thomas Fruergaard

    2013-08-01

    Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incineration, mechanical-biological treatment (MBT), and landfilling). In total, 252 scenarios were evaluated, including effects from source-segregation, waste composition, and energy conversion pathway efficiencies. Overall, the waste refinery provided global warming (GW) savings comparable with efficient incineration, MBT, and bioreactor landfilling technologies. The main environmental benefits from waste refining were a potential for improved phosphorus recovery (about 85%) and increased electricity production (by 15-40% compared with incineration), albeit at the potential expense of additional toxic emissions to soil. Society's need for the outputs from waste, i.e., energy products (electricity vs transport fuels) and resources (e.g., phosphorus), and the available waste composition were found decisive for the selection of future technologies. On the basis of the results, it is recommended that a narrow focus on GW aspects should be avoided as most waste technologies may allow comparable performance. Rather, other environmental aspects such as resource recovery and toxic emissions should receive attention in the future. PMID:23834059

In addition, a range of theoretical approaches are integrated that have examined the links between absorption capacity and relational network.

  8. Meeting the challenges related to material issues in chemical industries

    Baldev Raj; U Kamachi Mudali; T Jayakumar; K V Kasiviswanathn; K Natarajan

    2000-12-01

    Reliable performance and profitability are two important requirements for any chemical industry. In order to achieve high level of reliability and excellent performance, several issues related to design, materials selection, fabrication, quality assurance, transport, storage, inputs from condition monitoring, failure analysis etc. have to be adequately addressed and implemented. Technology related to nondestructive testing and monitoring of the plant is also essential for precise identification of defect sites and to take appropriate remedial decision regarding repair, replacement or modification of process conditions. The interdisciplinary holistic approach enhances the life of critical engineering components in chemical plants. Further, understanding the failure modes of the components through the analysis of failed components throws light on the choice of appropriate preventive measures to be taken well in advance, to have a control over the overall health of the plant. The failure analysis also leads to better design modification and condition monitoring methodologies, for the next generation components and plants. At the Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, a unique combination of the expertise in design, materials selection, fabrication, NDT development, condition monitoring, life prediction and failure analysis exists to obtain desired results for achieving high levels of reliability and performance assessment of critical engineering components in chemical industries. Case studies related to design, materials selection and fabrication aspects of critical components in nuclear fuel reprocessing plants, NDT development and condition monitoring of various components of nuclear power plants, and important failure investigations on critical engineering components in chemical and allied industries are discussed in this paper. Future directions are identified and planned approaches are briefly described.

  9. Analyses of natural resources in 10 CFR Part 60 as related to inadvertent human intrusion

    The purpose of this paper is to examine the intent of the regulatory language of the portions of 10 CFR Part 60 which deal with considerations of the natural resources of a proposed geologic repository for high-level radioactive wastes as they relate to inadvertent human intrusion. Four Potentially Adverse Conditions (PAC) the requirements of 10 CFR 60.21(c)(13) are shown to be related to natural resources. Groundwater is identified as a natural resource known to be present at Yucca Mountain, Nevada. For economic considerations of natural resources, the open-quotes foreseeable futureclose quotes is thought to be no more than 50 years. Two of the topics addressed by the PACs, subsurface mining and drilling at a proposed repository site, are pre-site-characterization activities which must be evaluated in the context of repository performance criteria set by the US EPA standard, 40 CFR Part 191. An alternative US DOE compliance demonstration to another PAC, 10 CFR 60.122(c)(17), might be to use an open-quotes explorationist perspectiveclose quotes of natural resource assessment. The Commission intends for DOE to evaluate the likelihood and consequence of inadvertent human intrusion into a geologic repository as a result of exploration or exploitation of natural resources within or near a proposed high-level radioactive waste geologic repository

  10. Coordination Mechanism of the Legal Protection of Resource Security with Its Relative Laws

    Chen Demin; Wang Huabing

    2008-01-01

    The basis of the legal protection of resource security is its relative laws, which have four main characteristics, which are foundational, divergent, comprehensive and of long-term social benefits in view. The coordination mechanism of the legal protection of resource security with its relative laws meets the needs of the sustainable development of the economy, society and environment. It also facilitates and is facilitated by the modern transformation of the legal system in China, and upholds the legal system as a logically self-perfecting entity. Furthermore, this coordination bears scientific feasibility.

  14. Volcano-related materials in concretes: a comprehensive review.

    Cai, Gaochuang; Noguchi, Takafumi; Degée, Hervé; Zhao, Jun; Kitagaki, Ryoma

    2016-04-01

    Massive volcano-related materials (VRMs) erupted from volcanoes bring the impacts to natural environment and humanity health worldwide, which include generally volcanic ash (VA), volcanic pumice (VP), volcanic tuff (VT), etc. Considering the pozzolanic activities and mechanical characters of these materials, civil engineers propose to use them in low carbon/cement and environment-friendly concrete industries as supplementary cementitious materials (SCMs) or artificial/natural aggregates. The utilization of VRMs in concretes has attracted increasing and pressing attentions from research community. Through a literature review, this paper presents comprehensively the properties of VRMs and VRM concretes (VRMCs), including the physical and chemical properties of raw VRMs and VRMCs, and the fresh, microstructural and mechanical properties of VRMCs. Besides, considering environmental impacts and the development of long-term properties, the durability and stability properties of VRMCs also are summarized in this paper. The former focuses on the resistance properties of VRMCs when subjected to aggressive environmental impacts such as chloride, sulfate, seawater, and freezing-thawing. The latter mainly includes the fatigue, creep, heat-insulating, and expansion properties of VRMCs. This study will be helpful to promote the sustainability in concrete industries, protect natural environment, and reduce the impacts of volcano disaster. Based on this review, some main conclusions are discussed and important recommendations regarding future research on the application of VRMs in concrete industries are provided. PMID:26865491

  15. Microstructure-fracture-permeability relations in cemented granular materials

    In this work, we investigate the relationships between the microstructure of cemented granular materials, morphology of cracks that may appear under tensile loading and their apparent permeability. In order to simulate the complexity of the multiphase heterogeneous structure of these materials, a numerical approach based on a lattice discretization was developed and used to study the mechanisms that control their behavior and rupture. Three distinct regimes of crack propagation were evidenced in terms of the combined influence of the matrix volume fraction and particle/matrix adherence. In the context of nuclear safety and in view of analyzing cracked concrete tightness, a methodology is proposed for generating representative microstructures with controlled phase volume fractions and particle size distributions. The cracks obtained under tensile loading are analyzed and a relationship is obtained between the microstructure of concrete and the tortuosity of the cracks. The permeability of cracked numerical microstructures was obtained by the simulation of liquid flow through the cracks by means of the Lattice Boltzmann method. Finally, a microstructure-tortuosity-permeability relation is proposed. The modeling and analysis tools developed in this work are generic enough to be applied to other complex multiphase heterogeneous materials. (author)

    Wen-Tien Tsai

    2012-08-01

    Full Text Available Biosludge is a by-product of secondary wastewater treatment processes. Due to its high contents of organic carbon and plant nutrients, this bioresource can be practically reused as raw feedstock for making organic fertilizers and building materials. The objective of this paper was to provide a preliminary analysis of biosludge utilization in Taiwan, including food processing sludge, wine brewery sludge, textile sludge, pulp sludge and agricultural sludge. The discussion focused on the status of biosludge generation in recent years (2004–2010, and its sustainable management principle. This paper also presents updated information about the governmental regulations and policies for promoting these biosolids as material resources, as well as validating the regulatory levels of toxic constituents in the biosludge and its derived product (e.g., organic fertilizer. Based on the preliminary benefit analysis of utilizing biosludge as raw material for organic fertilizer, reusing biosludge, being a beneficial resource, should be superior to those by traditional treatments (i.e., incineration and sanitary landfill.

  1. The role of material engineering within the concept of an integrated water resources management

    Breiner, Raphael; Müller, Harald S.

    2016-05-01

    By means of a case study, the successful implementation of a rheologically optimised cement-based mortar for the construction as well as for the rehabilitation of rain water cisterns is presented in this paper. The material was developed within the scope of a German-Indonesian joint project ["Integrated Water Resources Management" (IWRM)], funded by the German Federal Ministry of Education and Research. Comprehensive rheological investigations are presented which provide the database for the optimization of the mortar with regard to its intended range of application. For the selection of the source materials, special emphasis was placed on the ready availability at low cost. The rheological properties of the fresh mortar allow an easy workability by hand while the hardened mortar shows a durable and tight appearance at the same time. The developed material can be used as a coating for walls, floors and ceilings of cisterns, for the local rehabilitation of damaged areas only or even as a construction material for complete new cisterns. The future multiplication of the IWRM project results within the region was assured by a local capacity development when the presented material concept was applied in practise in Indonesia for the construction of sustainable rain water cisterns in Gunung Kidul.

In turn, it emphasizes the innovative practices employed by women residents of colonias to prepare meals under these constraints.

  12. Field-Flow Fractionation of Carbon Nanotubes and Related Materials

    John P. Selegue

    2011-11-17

    During the grant period, we carried out FFF studies of carbonaceous soot, single-walled and multi-walled carbon nanotubes, carbon nano-onions and polyoxometallates. FFF alone does not provide enough information to fully characterize samples, so our suite of characterization techniques grew to include light scattering (especially Photon Correlation Spectroscopy), scanning and transmission electron microscopy, thermogravimetric analysis and spectroscopic methods. We developed convenient techniques to deposit and examine minute FFF fractions by electron microscopy. In collaboration with Arthur Cammers (University of Kentucky), we used Flow Field-Flow Fractionation (Fl-FFF) to monitor the solution-phase growth of keplerates, a class of polyoxometallate (POM) nanoparticles. We monitored the evolution of Mo-POM nanostructures over the course of weeks by by using flow field-flow fractionation and corroborated the nanoparticle structures by using transmission electron microscopy (TEM). Total molybdenum in the solution and precipitate phases was monitored by using inductively coupled plasma analyses, and total Mo-POM concentration by following the UV-visible spectra of the solution phase. We observe crystallization-driven formation of (Mo132) keplerate and solution phase-driven evolution of structurally related nanoscopic species (3-60 nm). FFF analyses of other classes of materials were less successful. Attempts to analyze platelets of layered materials, including exfoliated graphite (graphene) and TaS2 and MoS2, were disappointing. We were not able to optimize flow conditions for the layered materials. The metal sulfides react with the aqueous carrier liquid and settle out of suspension quickly because of their high density.

  14. Health-related rehabilitation services: assessing the global supply of and need for human resources

    Landry Michel D

    2011-10-01

    Full Text Available Abstract Background Human resources for rehabilitation are often a neglected component of health services strengthening and health workforce development. This may be partly related to weaknesses in the available research and evidence to inform advocacy and programmatic strategies. The objective of this study was to quantitatively describe the global situation in terms of supply of and need for human resources for health-related rehabilitation services, as a basis for strategy development of the workforce in physical and rehabilitation medicine. Methods Data for assessing supply of and need for rehabilitative personnel were extracted and analyzed from statistical databases maintained by the World Health Organization and other national and international health information sources. Standardized classifications were used to enhance cross-national comparability of findings. Results Large differences were found across countries and regions between assessed need for services requiring health workers associated to physical and rehabilitation medicine against estimated supply of health personnel skilled in rehabilitation services. Despite greater need, low- and middle-income countries tended to report less availability of skilled health personnel, although the strength of the supply-need relationship varied across geographical and economic country groupings. Conclusion The evidence base on human resources for health-related rehabilitation services remains fragmented, the result of limited availability and use of quality, comparable data and information within and across countries. This assessment offered the first global baseline, intended to catalyze further research that can be translated into evidence to support human resources for rehabilitation policy and practice.

  15. INIS-based Japanese literature materials of bibliographic tools for human resource development

    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)

  16. Geo-material microfluidics at reservoir conditions for subsurface energy resource applications.

    Porter, Mark L; Jiménez-Martínez, Joaquín; Martinez, Ricardo; McCulloch, Quinn; Carey, J William; Viswanathan, Hari S

    2015-10-21

    Microfluidic investigations of flow and transport in porous and fractured media have the potential to play a significant role in the development of future subsurface energy resource technologies. However, the majority of experimental systems to date are limited in applicability due to operating conditions and/or the use of engineered material micromodels. We have developed a high pressure and temperature microfluidic experimental system that allows for direct observations of flow and transport within geo-material micromodels (e.g. rock, cement) at reservoir conditions. In this manuscript, we describe the experimental system, including our novel micromodel fabrication method that works in both geo- and engineered materials and utilizes 3-D tomography images of real fractures as micromodel templates to better represent the pore space and fracture geometries expected in subsurface formations. We present experimental results that highlight the advantages of using real-rock micromodels and discuss potential areas of research that could benefit from geo-material microfluidic investigations. The experiments include fracture-matrix interaction in which water imbibes into the shale rock matrix from etched fractures, supercritical CO2 (scCO2) displacing brine in idealized and realistic fracture patterns, and three-phase flow involving scCO2-brine-oil.

  17. Agricultural wastes as a resource of raw materials for developing low-dielectric glass-ceramics

    Danewalia, Satwinder Singh; Sharma, Gaurav; Thakur, Samita; Singh, K.

    2016-04-01

    Agricultural waste ashes are used as resource materials to synthesize new glass and glass-ceramics. The as-prepared materials are characterized using various techniques for their structural and dielectric properties to check their suitability in microelectronic applications. Sugarcane leaves ash exhibits higher content of alkali metal oxides than rice husk ash, which reduces the melting point of the components due to eutectic reactions. The addition of sugarcane leaves ash in rice husk ash promotes the glass formation. Additionally, it prevents the cristobalite phase formation. These materials are inherently porous, which is responsible for low dielectric permittivity i.e. 9 to 40. The presence of less ordered augite phase enhances the dielectric permittivity as compared to cristobalite and tridymite phases. The present glass-ceramics exhibit lower losses than similar materials synthesized using conventional minerals. The dielectric permittivity is independent to a wide range of temperature and frequency. The glass-ceramics developed with adequately devitrified phases can be used in microelectronic devices and other dielectric applications.

  19. Age-related decline in brain resources modulates genetic effects on cognitive functioning

    Lars Bäckman

    2008-12-01

    Full Text Available Individual differences in cognitive performance increase from early to late adulthood, likely reflecting influences of a multitude of factors. We hypothesize that losses in neurochemical and anatomical brain resources in normal aging modulate the effects of common genetic variations on cognitive functioning. Our hypothesis is based on the assumption that the function relating brain resources to cognition is nonlinear, so that genetic differences exert increasingly large effects on cognition as resources recede from high to medium levels in the course of aging.Direct empirical support for this hypothesis comes from a study by Nagel et al. (2008, who reported that the effects of the Catechol-O-Methyltransferase (COMT gene on cognitive performance are magnified in old age and interacted with the Brain-Derived Neurotrophic Factor (BDNF gene. We conclude that common genetic polymorphisms contribute to the increasing heterogeneity of cognitive functioning in old age. Extensions of the hypothesis to other polymorphisms are discussed.

  4. The availability of attentional resources modulates the inhibitory strength related to weakly activated priming.

    Wang, Yongchun; Wang, Yonghui; Liu, Peng; Dai, Dongyang; Di, Meilin; Chen, Qiang

    2016-08-01

    The current study investigated the role of attention in inhibitory processes (the inhibitory processes described in the current study refer only to those associated with masked or flanked priming) using a mixed paradigm involving the negative compatibility effect (NCE) and object-based attention. Accumulating evidence suggests that attention can be spread more easily within the same object, which increases the availability of attentional resources, than across different objects. Accordingly, we manipulated distractor location (with primes presented in the same object versus presented in different objects) together with prime/target compatibility (compatible versus incompatible) and prime-distractor stimulus onset asynchrony (SOA, 23 ms vs 70 ms). The aim was to investigate whether inhibitory processes related to weakly activated priming, which have been previously assumed to be automatic, depend on the availability of attentional resources. The results of Experiment 1 showed a significant NCE for the 70-ms SOA when the prime and distractor were presented in the same object (greater attentional resource availability); however, reversed NCEs were obtained for all other conditions. Experiment 2 was designed to disentangle whether the results of Experiment 1 were affected by the prime position, and the results indicated that the prime position did not modulate the NCE in Experiment 1. Together, these results are consistent with the claim that the availability of attentional resources modulates the inhibitory strength related to weakly activated priming. Specifically, if attentional resources are assigned to the distractor when it is presented in the same object as the prime, the strength of the inhibition elicited by the distractor may increase and reverse the activation elicited by the prime, which could lead to a significant NCE.

  10. IAEA mode-related research in the safe transport of radioactive material

    The International Atomic Energy Agency sponsors Co-ordinated Research Programmes (CRP) in the safe transport of radioactive material. The CRPs are intended to encourage research by Member States in identified areas and to facilitate co-ordination of exchange of information and resources to reach a common understanding of the problem and alternative solutions. Two of these programmes are: Accident Severity at Sea During the Transport of Radioactive Material and Accident Severity During the Air Transport of Radioactive Material. This paper will discuss these two programmes and their relationship to the continuing regulatory revision process and interfaces with the International Maritime Organization (IMO) and the International Civil Aviation Organization (ICAO). Some Member States and non-governmental organizations in IMO meetings expressed concerns that accidents on board ships may be more severe than the IAEA regulatory tests account for, and that package failure with subsequent release of radioactive material may occur. The CRP on accident severity at sea was established to develop further quantitative information on potential accident severities during the transport of radioactive material by ships. The primary objective of this programme is to collect and evaluate statistical data of marine accidents, perform analyses of potential accident conditions and evaluate the risks resulting from such shipments. The CRP on air transport was established to make a major international effort to collect relevant frequency and severity data and to analyze it so the accident forces to which a packages of radioactive material might be subjected to in a severe air accident can be more confidently quantified. Several countries have ongoing data collection activities related to aircraft accidents and severity and other sources of statistics for in-flight aircraft accidents will be explored. The International Civil Aviation Organization informed the IAEA of their plans to improve

Such actions would not only benefit the US nuclear reactor manufacturers, but also the US electric utilities that use nuclear reactors

  13. The new UN international framework classification for reserves/resources and its relation to uranium resource classification

    Resources traditionally are classified according to the degree of geological confidence and economic attractiveness. Various names are in use to describe nationally the different resource categories. Commonly, proven, probable or A+B are terms for the category RESERVES, meaning the recoverable portion of a resource under prevailing economic conditions. Since 1965 uranium resources are classified by the Nuclear Energy Agency of OECD and International Atomic Energy Agency using the terms Reasonably Assured Resources (RAR) and Estimated Additional Resources (EAR) in combination with cost categories. The definitions for RAR and EAR have been refined over the time and cost categories have been adapted according to market developments. For practical purposes a comparison of RAR and EAR with major national classification systems is provided in each of the NEA-IAEA publication on 'Uranium Resources Production and Demand' (Red Book). RAR of uranium are defined as quantities recoverable at given production costs with proven mining and processing technology, commonly RAR of the lowest cost category are referred to as Reserves. In 1992 the Committee on Energy - Working Party on Coal of the UN Economic Commission for Europe (UN/ECE) started to develop a new scheme for resource classification under the coordination of one of the authors (Kelter). The main purpose was to create an instrument permitting the classification of reserves and resources on an internationally consistent and uniform basis using market economic criteria. In April 1997 the UN/ECE approved the new 'United Nations International Framework Classification for Reserves/Resources-Solid Fuels and Mineral Commodities' at its 50th Anniversary Session. The new classification will enable the incorporation of national systems into an unified framework in order to make them compatible and comparable. Assistance will be given to economies in transition in reassessing their deposits according to market economy criteria and

    The transport of radioactive material has raised great interest on the part of national regulatory authorities, thus resulting in a safety measures improvement for all kinds of transportation. The transport of radioactive material is regulated by safety criteria much more than those applied to conventional hazardous material. All radioactive material transportation run in Brazilian territory must be in accordance with what is established by the CNEN-NE 5.01 - Transport of Radioactive Material. There are other national and international regulations for radioactive material transportation, which have to be accomplished with and adopted during the operation of radioactive material transportation. The aim of this paper is to verify the criteria set up in the existing regulations and propose a consensus for all the intervening organizations in the regulation process for land, air or sea transportation. This kind of transportation can not depend on the efforts of only one person, a group of workers or even any governmental body, but must be instead a shared responsibility among workers, transport firms and all regulative transportation organizations.

    By way of introduction approaches to the systematic apprehension of the material removal by water jets up to 1000 bar are made. In drilling experiments the effects of jet dynamic are studied, using the controlled disintegration of the jet. Using model-layer-systems the removal of layers by the 'natural' disintegrating fluid-jet is examined. The mechanisms of material removal and the consequences on the praxis of cleaning are discussed. A concept to measure specially the effects of the dynamic jet components is developed. In conclusion aspects of progress in this methods of material removal are discussed. (orig.)

  20. Lagged effects of family-supportive organization perceptions and supervision in relation to generalized work-related resources.

    Matthews, Russell A; Toumbeva, Tatiana H

    2015-07-01

    In the present study, grounded in organizational support and social exchange theory, the dynamic lagged interplay between family supportive supervision (FSS), family supportive organization perceptions (FSOP), perceived organizational support (POS), and leader-member exchange (LMX) was examined. Data were collected from 435 respondents over 3 time points with 6-week lags between assessments. Consistent with theory, FSS had a significant lagged effect on FSOP, whereas the reverse relationship was not supported. Interestingly, contrary to conservation of resources theory, we did not find significant lagged effects between POS and FSOP. Results further indicated that LMX and FSS were reciprocally related over time, suggesting the potential for a dynamic, mutually beneficial exchange relationship between subordinates and supervisors. Theoretical implications and considerations for research and practice are discussed. (PsycINFO Database Record PMID:25402223

  1. Trace-element geochemistry of coal resource development related to environmental quality and health

    1980-01-01

    This report assesses for decision makers and those involved in coal resource development the environmental and health impacts of trace-element effects arising from significant increases in the use of coal, unless unusual precautions are invoked. Increasing demands for energy and the pressing need for decreased dependence of the United States on imported oil require greater use of coal to meet the nation's energy needs during the next decade. If coal production and consumption are increased at a greatly accelerated rate, concern arises over the release, mobilization, transportation, distribution, and assimilation of certain trace elements, with possible adverse effects on the environment and human health. It is, therefore, important to understand their geochemical pathways from coal and rocks via air, water, and soil to plants, animals, and ultimately humans, and their relation to health and disease. To address this problem, the Panel on Trace Element Geochemistry of Coal Resource Development Related to Health (PECH) was established. Certain assumptions were made by the Panel to highlight the central issues of trace elements and health and to avoid unwarranted duplication of other studies. Based on the charge to the Panel and these assumptions, this report describes the amounts and distribution of trace elements related to the coal source; the various methods of coal extraction, preparation, transportation, and use; and the disposal or recycling of the remaining residues or wastes. The known or projected health effects are discussed at the end of each section.

    Water-resource-related data for sites in Reno County, Kansas were compiled in cooperation with the Reno County Health Department as part of the Kansas Department of Health and Environment's Local Environmental Protection Program (LEPP). These data were entered into a relational data-base management system (RDBMS) to facilitate the spatial analysis required to meet the LEPP goals of developing plans for nonpoint-source management and for public- water-supply protection. The data in the RDBMS are organized into digital data sets. The data sets contain the water-resource-related data compiled by the U.S. Geological Survey for 958 wells; by the Kansas Department of Health and Environment for 3,936 wells; by the Kansas Department of Health and Environment for 51 wells, 18 public-water-supply distribution systems, and 7 streams; by the Kansas State Board of Agriculture for 643 wells and 23 streams or surface-water impoundments; and by well-drilling contractors and the Kansas Geological Survey for 96 wells. The data in these five data sets are available from the Reno County Health Department in Hutchinson, Kansas. (USGS)

  3. Algorithms for Relative Radiometric Correction in Earth Observing Systems Resource-P and Canopus-V

    Zenin, V. A.; Eremeev, V. V.; Kuznetcov, A. E.

    2016-06-01

    The present paper has considered two algorithms of the relative radiometric correction of information obtained from a multimatrix imagery instrument of the spacecraft "Resource-P" and frame imagery systems of the spacecraft "Canopus-V". The first algorithm is intended for elimination of vertical stripes on the image that are caused by difference in transfer characteristics of CCD matrices and CCD detectors. Correction coefficients are determined on the basis of analysis of images that are homogeneous by brightness. The second algorithm ensures an acquisition of microframes homogeneous by brightness from which seamless images of the Earth surface are synthesized. Examples of practical usage of the developed algorithms are mentioned.

  4. Final environmental statement related to the Plateau Resources Limited Shootering Canyon Uranium Project (Garfield County, Utah)

    The proposed action is the issuance of a Source Material License to Plateau Resources, Ltd., for the construction and operation of the proposed Shootering Canyon Uranium Project with a product (U3O8) production limited to 2.2 x 105 kg (4.9 x 105 lb) per year. Impacts to the area from the operation of the Shootering Canyon Uranium Project will include the following: alterations of up to 140 ha (350 acres) that will be occupied by the mill, mill facilities, borrow areas, tailings areas, and roads; an increase in the existing background radiation levels of the mill area as a result of continuous but small releases of uranium, radium, radon, and other, radioactive materials during construction and operation; socioeconomic effects on the local area, particularly the proposed community of Ticaboo, where the majority of workers will be housed during project construction and operation; and production of solid waste material (tailings) from the mill at a rate of about 680 MT (750 tons) per day and deposition as a slurry in an onsite impoundment area; construction and operation of the Shootering Canyon mill will provide employment and induced economic benefits for the region but may also result in some socioeconomic stress. On the basis of the analysis and evaluation set forth in this Environmental Statement, it is proposed that any license issued for the Shootering Canyon mill should be subject to certain conditions for the protection of the environment.

  8. The inhalation of radioactive materials as related to hand contamination

    Bailey, J.C.; Rohr, R.C.

    1953-09-15

    Tests performed to determine the hazard associated with the inhalation of radioactive materials as the result of smoking with contaminated hands indicate that for dry uranium compounds adhering to the palmar surfaces of the hands, approximately 1.0% of the material may be transferred to a cigarette, and that of this approximately 0.2% may appear in the smoke which is inhaled. Most of the contamination originally placed in a cigarette was found in the ash, and only 11% of the material was not recovered following burning; approximately half of this loss may be attributed to normal losses inherent in the analytical process, the recovery efficiency for which was found by supplementary experiments to be 95%.

Beyond this indication we argue of the possibility that historical materialism can be recognised as explanatory system, as one that in derivation and maturity has as its focus of analysis and particularly lays emphasis on what more than ever before governs our social world today, capitalism. The cold war proved the ground or rather the fit for concealing the social and economic divide and made that division namely in competing strategic interest: with the failure of communism and the freeing of historical materialism itself, IR might as well accept the degree to which socio-economic issues determined its agenda and policy of the west.

  14. Laboratory and field studies related to the Hydrologic Resources Management Program. Progress report, October 1, 1993--September 30, 1994

    This report describes the work done at Los Alamos in FY 1994 for the Hydrologic Resources Management Program, a multi-organization project funded by the US Department of Energy/Nevada Operations Office. The authors participated in cooperative collaborations with University of California (UC), Berkeley, the Yucca Mountain Project, the Underground Test Area Operable Unit, and other participating organizations within the Hydrologic Resources Management Program (HRMP). They provided operational support to the Nevada Test Site (NTS) organizations by testing a water-evaporation system, championing the use of high-sensitivity logging equipment during drillbacks, and participating in the planning and execution of drilling operations at two nuclear test sites. Los Alamos personnel cooperated in preparing a proposal to drill beside and under a nuclear test located in unsaturated media. The authors gave assistance in laboratory work related to colloid migration and actinide sorption. In conjunction with personnel from the Lawrence Livermore Laboratory, they collected water samples from 10 wells at the NTS that are known to contain radionuclides. Their analyses of these samples suggest that radionuclides may not be moving away from cavity zones at appreciable rates. Recent field sampling shows clearly the need to purge wells of materials introduced during drilling and illustrates the inconsistency between water samples taken by bailing and those taken by pumping. 36 refs

    Full Text Available In this paper, we explore presence of collocational relations in the computer-assisted language learning systems and other language resources for the Japanese language, on one side, and, in the Japanese language learning textbooks and wordlists, on the other side. After introducing how important it is to learn collocational relations in a foreign language, we examine their coverage in the various learners’ resources for the Japanese language. We particularly concentrate on a few collocations at the beginner’s level, where we demonstrate their treatment across various resources. A special attention is paid to what is referred to as unpredictable collocations, which have a bigger foreign language learning-burden than the predictable ones.-----V tem članku raziskujemo prisotnost kolokacijskih odnosov v sistemih za računalniško podprto učenje in drugih jezikovnih virov za japonski jezik, na eni strani, in v materialih za učenje japonskega jezika za tujce, na drugi strani.

  16. Unconformity-related uranium-gold deposits of northern Australia: Resources, genesis and exploration

    Australia has a uranium resource of 370 kt U3O8 (313 kt U) contained in unconformity-related deposits. Over 85% of this resource is located in the Alligator Rivers Province of the Northern Territory. In addition to uranium, several of the deposits here contain economic gold (38t have so far been delineated) and two contain major amounts of platinum-group metals. Uranium-gold deposits of the Alligator Rivers Provinces are in many ways similar to deposits of the Athabasca Basin in Saskatchewan (Canada). They are located at the unconformity between Mid Proterozoic clastic rocks and older metamorphic basement. Ore is associated with fault zones which in some cases transgress and offset the unconformity. Ore is enveloped by intense clay-sized phyllosilicate alteration haloes. Differences (i.e. lower grade, no ore in sandstone, no Ni-Co-As ore) can largely be attributed to the effects of extensive erosion and weathering which has exposed the Alligator Rivers deposits, and overall lack of exploration in areas of thick sandstone cover. All the known deposits in the Alligator Rivers Province were discovered by relatively simple airborne or ground radiometric surveys. Modern, geophysical methods as are routinely employed in Saskatchewan (such as airborne TEM), have not been tried in the Alligator Rivers Province. There has been a paucity of exploration in the Alligator Rivers Province in the past 15 years, as a result of creation of a national park over the most prospective area.

    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.

  20. An examination of network position and childhood relational aggression: integrating resource control and social exchange theories.

    Neal, Jennifer Watling; Cappella, Elise

    2012-01-01

    Applying resource control theory and social exchange theory, we examined the social network conditions under which elementary age children were likely to engage in relational aggression. Data on classroom peer networks and peer-nominated behaviors were collected on 671 second- through fourth-grade children in 34 urban, low-income classrooms. Nested regression models with robust cluster standard errors demonstrated that the association between children's number of relationships and their levels of relational aggression was moderated by the number of relationships that their affiliates had. Children with more peer relationships (i.e., higher network centrality) exhibited higher levels of relational aggression, but only when these relationships were with peers who had fewer connections themselves (i.e., poorly connected peers). This finding remained significant even when controlling for common predictors of relational aggression including gender, overt aggression, prosocial behavior, victimization, social preference, and perceived popularity. Results are discussed in terms of their implications for advancing the literature on childhood relational aggression and their practical applications for identifying children at risk for these behaviors.

  1. An approach to classifying human resources constraints to attaining health-related Millennium Development Goals

    Wyss Kaspar

    2004-07-01

    Full Text Available Abstract Background For any wide-ranging effort to scale up health-related priority interventions, human resources for health (HRH are likely to be a key to success. This study explores constraints related to human resources in the health sector for achieving the Millennium Development Goals (MDGs in low-income countries. Methods and framework The analysis drew on information from a variety of publicly-available sources and principally on data presented in published papers in peer-reviewed journals. For classifying HRH constraints an analytical framework was used that considers constraints at five levels: individual characteristics, the health service delivery level, the health sector level, training capacities and the sociopolitical and economic context of a country. Results and discussion At individual level, the decision to enter, remain and serve in the health sector workforce is influenced by a series of social, economic, cultural and gender-related determinants. For example, to cover the health needs of the poorest it is necessary to employ personnel with specific social, ethnic and cultural characteristics. At health-service level, the commitment of health staff is determined by a number of organizational and management factors. The workplace environment has a great impact not only on health worker performance, but also on the comprehensiveness and efficiency of health service delivery. At health-sector level, the use of monetary and nonmonetary incentives is of crucial importance for having the accurate skill mix at the appropriate place. Scaling up of priority interventions is likely to require significant investments in initial and continuous training. Given the lead time required to produce new health workers, such investments must occur in the early phases of scaling up. At the same time coherent national HRH policies are required for giving direction on HRH development and linking HRH into health-sector reform issues, the scaling

  2. SEARCHBreast: a new resource to locate and share surplus archival material from breast cancer animal models to help address the 3Rs.

    Blyth, Karen; Carter, Phil; Morrissey, Bethny; Chelala, Claude; Jones, Louise; Holen, Ingunn; Speirs, Valerie

    2016-04-01

    Animal models have contributed to our understanding of breast cancer, with publication of results in high-impact journals almost invariably requiring extensive in vivo experimentation. As such, many laboratories hold large collections of surplus animal material, with only a fraction being used in publications relating to the original projects. Despite being developed at considerable cost, this material is an invisible and hence an underutilised resource, which often ends up being discarded. Within the breast cancer research community there is both a need and desire to make this valuable material available for researchers. Lack of a coordinated system for visualisation and localisation of this has prevented progress. To fulfil this unmet need, we have developed a novel initiative called Sharing Experimental Animal Resources: Coordinating Holdings-Breast (SEARCHBreast) which facilitates sharing of archival tissue between researchers on a collaborative basis and, de facto will reduce overall usage of animal models in breast cancer research. A secure searchable database has been developed where researchers can find, share, or upload materials related to animal models of breast cancer, including genetic and transplant models. SEARCHBreast is a virtual compendium where the physical material remains with the original laboratory. A bioanalysis pipeline is being developed for the analysis of transcriptomics data associated with mouse models, allowing comparative study with human and cell line data. Additionally, SEARCHBreast is committed to promoting the use of humanised breast tissue models as replacement alternatives to animals. Access to this unique resource is freely available to all academic researchers following registration at https://searchbreast.org . PMID:27083180

  3. Quantitative property-structural relation modeling on polymeric dielectric materials

    Wu, Ke

    Nowadays, polymeric materials have attracted more and more attention in dielectric applications. But searching for a material with desired properties is still largely based on trial and error. To facilitate the development of new polymeric materials, heuristic models built using the Quantitative Structure Property Relationships (QSPR) techniques can provide reliable "working solutions". In this thesis, the application of QSPR on polymeric materials is studied from two angles: descriptors and algorithms. A novel set of descriptors, called infinite chain descriptors (ICD), are developed to encode the chemical features of pure polymers. ICD is designed to eliminate the uncertainty of polymer conformations and inconsistency of molecular representation of polymers. Models for the dielectric constant, band gap, dielectric loss tangent and glass transition temperatures of organic polymers are built with high prediction accuracy. Two new algorithms, the physics-enlightened learning method (PELM) and multi-mechanism detection, are designed to deal with two typical challenges in material QSPR. PELM is a meta-algorithm that utilizes the classic physical theory as guidance to construct the candidate learning function. It shows better out-of-domain prediction accuracy compared to the classic machine learning algorithm (support vector machine). Multi-mechanism detection is built based on a cluster-weighted mixing model similar to a Gaussian mixture model. The idea is to separate the data into subsets where each subset can be modeled by a much simpler model. The case study on glass transition temperature shows that this method can provide better overall prediction accuracy even though less data is available for each subset model. In addition, the techniques developed in this work are also applied to polymer nanocomposites (PNC). PNC are new materials with outstanding dielectric properties. As a key factor in determining the dispersion state of nanoparticles in the polymer matrix

  4. Relation between physicomechanical properties and diffusion phenomena in composite materials

    One of the procedures for storing low and medium activity nuclear waste consists of coating the contaminated material in a thermosetting resin. The drums thus constitued are stored in concreted underground trenches, then covered with cement, bitumen or clayey soil. Although the risk of water circulation is low, this element represents on the one hand the major cause of natural deterioration of the polymer, and on the other hand the most likely vehicle for conveying the radioactive ions confined in the drums. It is for this reason that the study of the behaviour of polyester or epoxide-based macromolecular materials with regard to water constitutes the first stage of this work. The second part of the thesis is directed towards the study of compound materials. Indeed, the charges are represented in the first case by the nuclear waste itself; in the second case, they are introduced into the polymer beforehand, on the one hand to reduce costs, and on the other hand to give the mixture suitable mechanical and rheological properties. In this study, three types of mineral charge are added in an epoxide resin: glass balls surface-treated or not, and sand. Various techniques are implemented in order to assess and characterize the interfacial adhesion, in the different systems. The strongest polymer-charge bonds are sought in order to resist natural deterioration. Finally, the object of the confinement process, is to avoid dispersion of low and medium activity substances (137Cs, 90Sr, 60Co, 106Ru..) in the environment. The final stage of this work therefore consists in assessing the barrier qualities of pure or charged polymers with regard to radioactive ion diffusion. We will show in particular that the use of fine resin membranes enables the diffusion coefficient of the 137Cs to be calculated

  6. Age-Related Changes in Children’s Associations of Economic Resources and Race

    Elenbaas, Laura; Killen, Melanie

    2016-01-01

    Age-related changes in children’s associations of economic resources and race were investigated. The sample (N = 308) included 5–6 year-olds (n = 153, M = 6.01 years, SD = 0.33 years) and 10–11 year-olds (n = 155, M = 11.12 years, SD = 0.59 years) of African–American (n = 93), European–American (n = 92), Latino (n = 62), Asian–American (n = 23), and multi-racial or multi-ethnic (n = 26) background. Participants matched pairs of target children (African–American and European–American) with visual indicators of low, middle, and high economic status. Children’s associations of economic resources with racial groups changed with age, and reflected different associations at high, middle, and low levels of the economic spectrum. Specifically, children associated targets of both races with middle economic status at a comparable rate, and with age, increasingly associated targets of both races with indicators of middle economic status. By contrast, both younger and older children associated African–American targets with indicators of low economic status more frequently than European–American targets. Finally, children associated African–American targets with indicators of high economic status less frequently with age, resulting in a perceived disparity in favor of European–American targets at high economic status among older children that was not present among younger children. No differences were found by participants’ own racial or ethnic background. These results highlight the need to move beyond a dichotomized view (rich or poor) to include middle economic status when examining children’s associations of economic resources and race.

  7. Changing Hydrological Cycle in Asian Monsoon Region in Relation to Water Resources

    Kabat, P.

    2006-12-01

    Water is a key resource for sustainable development in the Monsoon Asian Region. Frequent occurrence of flood disasters related to increasing Asian monsoon climate variability, progressing land degradation associated with anomalous monsoon dry climate and land overexploitation, increasing water use due to rapid social/economic development, and water pollution under the development of industrialization, urbanization and intensive agriculture, all pose fundamental questions about mid- and long term future carrying capacity of water systems in this key-region of the globe. We review some of the most recent data and methodological insights about how the hydrological cycle and hydroclimate in monsoon Asia is changing or has already changed in association with the global warming (GHG increase). Next,we analyze how regional-scale anthropogenic impacts such land cover/use changes, forest fire, dust increase, affect the hydrological cycle and water resources in the monsoon Asia and Northern China. The issues addressed in the presentation include: (i)the current regional hydrological cycle, especially causal chains leading to observable changes in droughts and floods;(ii)how the water cycle and the extremes may respond to future drivers of global change;(iii) feedbacks in the coupled system as they affect the hydrological cycle; (iv)the uncertainties in the predictions of coupled climate-hydrological- land use models and (v)the future vulnerability of water as a resource. We argue for a substantial increase of international collaborative research efforts into integrated impact assessment of climate change and human activity on water systems in this region.

  9. 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. PMID:22993131

    2016-04-01

    With advancement of medical interventions, the lifespan of people living with HIV has increased globally. However, low- and middle-income countries (LMICs) which bear the greatest burden of the HIV pandemic face a constant challenge in addressing the treatment needs of immune-suppressed patients. An analysis of the current management protocols and access to medication in resource-poor settings was conducted at this workshop, with emphasis on the situation in resource-poor settings. The participants developed a consensus document based on the need to respond to the constantly changing HIV pandemic. Provision of oral health care must be guided by interconnecting principles based on population based strategies that address upstream determinants of health. Basic oral health coverage in developing countries can only be realized with a strong foundation at the primary health level. Early diagnosis of HIV-related comorbidities including the adverse effects of ARVs is essential for the improvement of treatment outcomes. Standardization of oral health care delivery mechanisms will facilitate evaluation at national and regional levels. Oral health care workers have a moral obligation to participate in sustained campaigns to reduce the social stigma associated with HIV/AIDS in their work places at every stage of the referral chain. Future research also needs to realign itself towards prevention using the common risk factor approach, which has a broader impact on non-communicable diseases, which are increasingly affecting patients with HIV/AIDS as their life expectancies increase.

    The paper is a summary of Russian material studies performed in frames of activities aiming at substantiation of safety of the International Thermonuclear Experimental Reactor (ITER) after 2001. Subthreshold sputtering of tungsten by 5eV deuterons was revealed at temperatures above 1150rm oC. Mechanism of globular films formation was further studied. Computations of tritium permeation into vacuum vessel coolant confirmed the acceptability of vacuum vessel cooling system for removal of the decay heat. The most dangerous accident with high-current arc in toroidal superconducting magnets able to burn out a bore up to 0.6 m in diameter in the cryostat vessel was determined. Radiochemical reprocessing of V-Cr-Ti alloy and its purification from activation products down to a contact dose rate of ~10muSv/h was developed.

  12. ARE OPPORTUNITIES DEMANDS AND RESOURCES RELATED TO STRESS ? A CRITICAL STUDY

    Harish .K

    2014-10-01

    Full Text Available Most of us are aware that employee stress is an increasing problem in organizations. Friends tell us they’re stressed out from greater workloads and having to work longer hours because of downsizing at their company. Parents talk about the lack of job stability in today’s world and reminisce about a time when a job with a large company implied lifetime security. We read surveys in which employees complain about the stress created in trying to balance work and family responsibilities. We’ll look at the causes and consequences of stress, and then consider what individuals and organizations can do to reduce it. Stress is a dynamic condition in which an individual is confronted with an opportunity, demand, or resource related to what the individual desires and for which the outcome is perceived to be both uncertain and important. This is a complicated definition.

  14. A Survey and Resource Materials on the Use of Oxygen Supplementation in Fish Culture.

    Colt, John; Orwicz, Kris; Bouck, Gerald R.

    1988-09-01

    Oxygen supplementation is the process by which naturally occurring dissolved oxygen (DO) is supplemented with enriched oxygen to restore or enhance DO levels in water. In aquaculture this is usually done with relatively pure oxygen and the result has significant potential to improve fish health, aid hatchery economic considerations, or both. For example, oxygen supplementation can preclude both hypoxia and gas bubble disease, as well as allow more fish to be reared in the same space or water or both. However, the concepts and technology in oxygen supplementation are evolving rapidly and direct communication with the user groups would foster technology transfer and improve implementation. Therefore we undertook and now report a survey of organizations that either currently use or plan to use oxygen supplementation. Additionally we included various pertinent material, including literature sources, lists of consultants and equipment manufacturers and some current research in oxygen supplementation.

Material and Method: 50% glycerol at equal amounts was intramuscularly administered to both hind legs of all animals under ether anesthesia at the dose of 10 mg/kg. Three hours later, the groups were administered the following: Group I (number:7: Iopromide(Ultravist -300® at the dose of 2 ml/kg (intracardiac; Group II (number:7: Iopromide(Ultravist -300® and intraperitoneally administered Melatonin at the dose of 10 mg/kg (Melatonin was dissolved in 7.5% absolute ethanol and further dilutions were made in saline.; and Group III (number:7: 2 ml/kg of sterile physiologic saline (Control group. The levels of Uurea, Ccreatinine and Ccystatin C were studied on the blood samples collected. The renal samples were evaluated by 2two distinct pathologists who did not know the protocol. Results: There was no difference in the values of Creatinine and cystatin c between Groups 2 and 3 (p=0.9; 0.2. Discussion: In conclusion, we evaluated the possible prevention of contrast-induced oxidative stress in the kidney with using melatonin. However, additional clinical studies are needed to evaluate the role of preventive melatonin treatment in humans.

  16. Addressing trend-related changes within cumulative effects studies in water resources planning

    Summarized herein are 28 case studies wherein trend-related causative physical, social, or institutional changes were connected to consequential changes in runoff, water quality, and riparian and aquatic ecological features. The reviewed cases were systematically evaluated relative to their identified environmental effects; usage of analytical frameworks, and appropriate models, methods, and technologies; and the attention given to mitigation and/or management of the resultant causative and consequential changes. These changes also represent important considerations in project design and operation, and in cumulative effects studies associated therewith. The cases were grouped into five categories: institutional changes associated with legislation and policies (seven cases); physical changes from land use changes in urbanizing watersheds (eight cases); physical changes from land use changes and development projects in watersheds (four cases); physical, institutional, and social changes from land use and related policy changes in river basins (three cases); and multiple changes within a comprehensive study of land use and policy changes in the Willamette River Basin in Oregon (six cases). A tabulation of 110 models, methods and technologies used in the studies is also presented. General observations from this review were that the features were unique for each case; the consequential changes were logically based on the causative changes; the analytical frameworks provided relevant structures for the studies, and the identified methods and technologies were pertinent for addressing both the causative and consequential changes. One key lesson was that the cases provide useful, “real-world” illustrations of the importance of addressing trend-related changes in cumulative effects studies within water resources planning. Accordingly, they could be used as an “initial tool kit” for addressing trend-related changes

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

    Mayombe, Celestin; Lombard, Antoinette

    2016-03-01

    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.

  20. Carbon and related materials for thermal and electrical applications

    Aoyagi, Yasuhiro

    High thermal stability has been attained in polyol ester by using a sterically half-hindered phenolic primary antioxidant and a thiopropionate secondary antioxidant. Carbon black and boron nitride (BN) serve as antioxidants in the presence of either primary antioxidant or secondary antioxidant at 200°C. BN paste shows an estimated 100°C lifetime of 19 years, compared to 1.3 years for the carbon black paste and 0.10 year for commercial silver paste. Phase-change materials (PCMs) with high thermal stability and high heat of fusion have been attained by using antioxidants (mainly hydrocarbons with linear segments). Their heat of fusion is much higher than those of commercial PCMs. The use of 98.0 wt.% thiopropionate antioxidant with 2.0 wt.% half-hindered phenolic antioxidant as the matrix and 16 vol.% BN particles gives 100°C lifetime indicator 5.3 years, in contrast to 0.95 year or less for the commercial PCMs. Carbon-based films with thickness 1-13 mum, electrical resistivity 6 x 10-4 - 3 O.cm, and strong bonding to alumina, have been attained through the use of EPON SU 2.5 epoxy and an amine curing agent as the carbon precursor, and a carbonization temperature of 650°C. Nickel nanoparticles (filamentary) are more effective for enhancing the conductivity than silver nanoparticles (not filamentary) at the same volume fraction. Even the combined use of carbon nanotube and silver is less effective than nickel. A three-dimensional microstructure in the form of a microscale bridge on alumina has been attained by using a novel low-cost process that involves thermoplastic spacer (wax) evaporation during pyrolysis of an epoxy-based film that coats the spacer and a part of the substrate. Multiwalled carbon nanotube as a filler is effective for reducing cracking during pyrolysis. A bridge with a girder of length 90-300 microm, separated from the substrate by a height of 5-15 mum, has been attained.

    Natural resource planning at all scales demands methods for assessing the impacts of resource development and use, and in particular it requires standardized methods that yield robust and unbiased results. Building from existing probabilistic methods for assessing the volumes of energy and mineral resources, we provide an algorithm for consistent, reproducible, quantitative assessment of resource development impacts. The approach combines probabilistic input data with Monte Carlo statistical methods to determine probabilistic outputs that convey the uncertainties inherent in the data. For example, one can utilize our algorithm to combine data from a natural gas resource assessment with maps of sage grouse leks and piñon-juniper woodlands in the same area to estimate possible future habitat impacts due to possible future gas development. As another example: one could combine geochemical data and maps of lynx habitat with data from a mineral deposit assessment in the same area to determine possible future mining impacts on water resources and lynx habitat. The approach can be applied to a broad range of positive and negative resource development impacts, such as water quantity or quality, economic benefits, or air quality, limited only by the availability of necessary input data and quantified relationships among geologic resources, development alternatives, and impacts. The framework enables quantitative evaluation of the trade-offs inherent in resource management decision-making, including cumulative impacts, to address societal concerns and policy aspects of resource development.

  2. Long-term relationships of major macro-variables in a resource-related economic model of Australia

    The paper reports the results of a simple cointegration analysis applied to bivariate causality models using data on resource output, oil prices, terms of trade, current account and output growth to investigate the long-term relationships among these major macroeconomic aggregates in a resource-related economic model of Australia. For the period 1960-1990, the empirical evidence indicates that these five macro-variables, as formulated in our model, are not random walks. In addition, resource production and oil prices are significantly cointegrated, and they are also significantly cointegrated with the current account, terms of trade and economic growth. These findings provide support to the long-term adjustments foundation of our resource-related model. (author)

    Community-run, formal evaluations and manually annotated text corpora are critically important for advancing biomedical text-mining research. Recently in BioCreative V, a new challenge was organized for the tasks of disease named entity recognition (DNER) and chemical-induced disease (CID) relation extraction. Given the nature of both tasks, a test collection is required to contain both disease/chemical annotations and relation annotations in the same set of articles. Despite previous efforts in biomedical corpus construction, none was found to be sufficient for the task. Thus, we developed our own corpus called BC5CDR during the challenge by inviting a team of Medical Subject Headings (MeSH) indexers for disease/chemical entity annotation and Comparative Toxicogenomics Database (CTD) curators for CID relation annotation. To ensure high annotation quality and productivity, detailed annotation guidelines and automatic annotation tools were provided. The resulting BC5CDR corpus consists of 1500 PubMed articles with 4409 annotated chemicals, 5818 diseases and 3116 chemical-disease interactions. Each entity annotation includes both the mention text spans and normalized concept identifiers, using MeSH as the controlled vocabulary. To ensure accuracy, the entities were first captured independently by two annotators followed by a consensus annotation: The average inter-annotator agreement (IAA) scores were 87.49% and 96.05% for the disease and chemicals, respectively, in the test set according to the Jaccard similarity coefficient. Our corpus was successfully used for the BioCreative V challenge tasks and should serve as a valuable resource for the text-mining research community.Database URL: http://www.biocreative.org/tasks/biocreative-v/track-3-cdr/.

  9. The Relative Richness of the Poor? Natural Resources, Human Capital and Economic Growth

    Bravo-Ortega, Claudio; De Gregorio, José

    2005-01-01

    What is the role of natural resources in economic performance? Are there any special conditions in which natural resources can act as the engine of growth? Are natural resources a curse? In this paper we present a model where natural resources have a positive effect on level of income and a negative effect on its growth rate. However, we show that this effect can be ameliorated by having a large level of human capital. We test our model using panel data for the period 1970-1990. We extend the...

The study was designed as an observational chart and billing data review of current and proposed payments, in the setting of a preoperative holing area, intraoperative suite, and post anesthesia care unit. In total, 1,195 charts of American Society of Anesthesiology (ASA physical status 1 through 5 patients were reviewed. No direct patient interventions were undertaken. Results: Spearman correlations between the proposed RBRVS billing matrix payments and the current ASA relative value guide methodology payments were strong (r=0.94–0.96, P<0.001 for training, test, and overall. The proposed RBRVS-based billing matrix yielded payments that were 3.0%±1.34% less than would have been expected from commercial insurers, using standard rates for commercial ASA relative value units and RBRVS relative value units. Compared with current Medicare reimbursement under the ASA relative value guide, reimbursement would almost double when converting to an RBRVS billing model. The greatest increases in Medicare reimbursement between the current system and proposed billing model occurred as anesthetic management complexity increased. Conclusion: The new crosswalk correlates with existing evaluation and management and intensive care medicine codes in an

    Many patients with psoriasis demonstrate psychological disturbances, including decreased health-related quality of life (HRQoL). The aim of this study was to evaluate selected personal resources and HRQoL in 168 in-patients with psoriasis vulgaris. The following questionnaires were used: Skindex-29, General Health Questionnaire, Coping with Skin Disease Scale, Acceptance of Illness Scale, Life Orientation Test, Multidimensional Health Locus of Control Scale and General Self-Efficacy Scale. It was demonstrated that younger patients experienced fewer problems in psychosocial functioning, and that they showed a correlation between worse HRQoL and both external powerful others and external chance domains in locus of health control. Subjective self-evaluation of health correlated with HRQoL irrespective of patient's age. Coping with stress strategies hopelessness/helplessness and distraction/catastrophization correlated with worse overall HRQoL, whereas fighting spirit strategy correlated with better overall HRQoL. Hopelessness/helplessness coping strategy, somatic symptoms, disease acceptance, psoriasis severity and patient's age explained 61% of overall HRQoL variance. Psychomedical interventions designed for psoriatic patients should take into account the above variables. PMID:23407910

  12. Use of magnetic carbon composites from renewable resource materials for oil spill clean up and recovery

    Viswanathan, Tito

    2015-10-27

    A method of separating a liquid hydrocarbon material from a body of water, includes: (a) mixing magnetic carbon-metal nanocomposites with a liquid hydrocarbon material dispersed in a body of water to allow the magnetic carbon-metal nanocomposites each to be adhered by the liquid hydrocarbon material to form a mixture; (b) applying a magnetic force to the mixture to attract the magnetic carbon-metal nanocomposites each adhered by the liquid hydrocarbon material; and (c) removing the body of water from the magnetic carbon-metal nanocomposites each adhered by the liquid hydrocarbon material while maintaining the applied magnetic force. The magnetic carbon-metal nanocomposites is formed by subjecting one or more metal lignosulfonates or metal salts to microwave radiation, in presence of lignin/derivatives either in presence of alkali or a microwave absorbing material, for a period of time effective to allow the carbon-metal nanocomposites to be formed.

  13. Integrated Resource Management and Recovery

    Astrup, Thomas Fruergaard

    2014-01-01

    A significant part of the environmental consequences related to activities in society is associated with our consumption of resources. Modern products become more and more complex and rely on more complex sets of resources than before. This emphasizes the need for continuous access to high quality...... resources, i.e. security of supply, but also the need for efficient recovery of the same resources after the use-phase of the products. While this recovery may appear simple, considerable challenges exist. Management and recovery of resources in waste materials, or in general residual streams in society......, depends on the quality of these resources and technological abilities to extract resources from mixed materials, e.g. mobile phones, solar cells, or mixed domestic waste. The "effort" invested in recovery of secondary resources should not be more than the "benefit" associated with the secondary resources...

  14. The relevance of the psychometrist category as a professional resource: Training-related issues

    René van Eeden

    2016-04-01

    Full Text Available Orientation: The professional status of psychometrists places them in a position where they can provide a specialist function independently and their services should therefore be relevant to a variety of settings.Research purpose: The aim was to explore if the training of student psychometrists contributes to the relevance of this category in terms of the demographic profile of student psychometrists, the scope of services potentially provided by them and the content of training programmes.Motivation for the study: There is a paucity of research on training in the psychometrist category.Research design, approach and method: Data were obtained from the files of a cohort of student psychometrists who were registered in the Department of Psychology at the University of South Africa (UNISA. Follow-up surveys on training and work contexts were conducted amongst these students and their in-practice supervisors to confirm and supplement the data. In addition, a survey on the national availability of training programmes for psychometrists was conducted at South African universities.Main findings: Gender and racial skewness in terms of the demographic profile of the UNISA students seemed to reflect a national trend. In terms of the scope of services, training opportunities and perceived job opportunities for psychometrists seemed limited and despite the utilisation of the skills area in all the applied contexts, concerns related to the sectors being served were identified. With regard to the content of the training programmes, students and in-practice supervisors expressed a need for greater preparation in test use before related practical experience takes place. The importance of the university’s involvement during the practicum was also emphasised.Practical/managerial implications: Recommendations are made regarding the structure and content of training programmes. This information could be applied in adapting existing programmes and in developing

  15. Variabilities in the mortality-related resource utilisation for congenital heart disease

    Danford, David A; Karels, Quentin; Kutty, Shelby

    2016-01-01

    Objective Our objective was to characterise the divergence of effort from outcome in congenital heart disease (CHD) care by measuring mortality-related resource utilisation fraction (MRRUF) for various CHD lesions across institutions of differing volumes. Methods Study design was observational analysis of an administrative database, the Pediatric Health Information System (PHIS). The setting was inpatient; 2004–2013. Patients were ≤21 years old with atrial septal defect (ASD), ventricular septal defect (VSD), tetralogy of Fallot (TOF), hypoplastic left heart syndrome (HLHS) or other single ventricle (SV). There were no interventions but diagnosis, institution (and volume), age, length of hospitalisation, billed charges and deaths were recorded. The main outcome measure was MRRUF, the ratio of investments during hospitalisations ending in fatality to investments during all hospitalisations. Results There were 50 939 admissions, 1711 deaths, 703 383 inpatient days, and $10 182 000 000 billed charges. MRRUF varied widely by diagnosis: highest in HLHS (21%), but present in ASD (2%) and VSD (4%). Highest among the very young, MRRUF also increased in HLHS and SV during adolescence. MRRUF increased with hospitalisation duration. MRRUF had no relation to institutional volume, and was static over the decade studied. Conclusions Even in the modern era we invest heavily in inpatient CHD care that does not produce the desired outcome. Although its magnitude varies by lesion and age, MRRUF is not limited to complex disease in the very young. MRRUF is not decreasing, and is not isolated to high or low volume institutions.

  18. The social relations of health care and household resource allocation in neoliberal Nicaragua

    Tesler Laura E

    2010-05-01

    Full Text Available Abstract Background With the transition to neoliberalism, Nicaragua's once-critically acclaimed health care services have substantially diminished. Local level social formations have been under pressure to try to bridge gaps as the state's role in the provision of health care and other vital social services has decreased. This paper presents a case study of how global and national health policies reverberated in the social relations of an extended network of female kin in a rural community during late 2002 - 2003. Methods The qualitative methods used in this ethnographic study included semi-structured interviews completed during bi-weekly visits to 51 households, background interviews with 20 lay and professional health practitioners working in the public and private sectors, and participant-observation conducted in the region's government health centers. Interviews and observational field notes were manually coded and iteratively reviewed to identify and conceptually organize emergent themes. Three households of extended kin were selected from the larger sample to examine as a case study. Results The ongoing erosion of vital services formerly provided by the public sector generated considerable frustration and tension among households, networks of extended kin, and neighbors. As resource allocations for health care seeking and other needs were negotiated within and across households, longstanding ideals of reciprocal exchange persisted, but in conditions of poverty, expectations were often unfulfilled, exposing the tension between the need for social support, versus the increasingly oppositional positioning of social network members as sources of competition for limited resources. Conclusions In compliance with neoliberal structural adjustment policies mandated by multilateral and bilateral agencies, government-provided health care services have been severely restricted in Nicaragua. As the national safety net for health care has been eroded

  20. 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.

  1. Air quality analysis and related risk assessment for the Bonneville Power Administration's Resource Program

    The Bonneville Power Administration (BPA) is considering 12 different alternatives for acquiring energy resources over the next 20 years. Each of the alternatives utilizes a full range of energy resources (e.g., coal, cogeneration, conservation, and nuclear); however, individual alternatives place greater emphases on different types of power-producing resources and employ different timetables for implementing these resources. The environmental impacts that would result from the implementation of each alternative and the economic valuations of these impacts, will be an important consideration in the alternative selection process. In this report we discuss the methods used to estimate environmental impacts from the resource alternatives. We focus on pollutant emissions rates, ground-level air concentrations of basic criteria pollutants, the acidity of rain, particulate deposition, ozone concentrations, visibility attenuation, global warming, human health effects, agricultural and forest impacts, and wildlife impacts. For this study, pollutant emission rates are computed by processing BPA data on power production and associated pollutant emissions. The assessment of human health effects from ozone indicated little variation between the resource alternatives. Impacts on plants, crops, and wildlife populations from power plant emissions are projected to be minimal for all resource alternatives

  2. Inventory and analysis of natural vegetation and related resources from space and high altitude photography

    Poulton, C. E.; Faulkner, D. P.; Johnson, J. R.; Mouat, D. A.; Schrumpf, B. J.

    1971-01-01

    A high altitude photomosaic resource map of Site 29 was produced which provided an opportunity to test photo interpretation accuracy of natural vegetation resource features when mapped at a small (1:133,400) scale. Helicopter reconnaissance over 144 previously selected test points revealed a highly adequate level of photo interpretation accuracy. In general, the reasons for errors could be accounted for. The same photomosaic resource map enabled construction of interpretive land use overlays. Based on features of the landscape, including natural vegetation types, judgements for land use suitability were made and have been presented for two types of potential land use. These two, agriculture and urbanization, represent potential land use conflicts.

  4. Relative Abundance of Renewable Resources in Asia and Europe and the Future Demand for Renewable Technologies

    Danielsson, Peter [European Renewable Energies Federation (Sweden)

    2005-12-15

    In Europe and in many other parts of the world, energy consumption has reached unsustainable levels. As such, efforts must be made both to expand the use of renewable energy and to reduce the total level of energy consumption. If there are any pertinent driving forces for this, they would be the need to reduce harmful emissions; to increase sustainable energy supply, security, poverty, eradication and access to dignity for billions of people - the ending of a vicious circle of exploitation of scarce natural resources for inefficient energy use. Most European nations belong to the relatively small group of wealthy countries enjoying a comparatively high standard of living. They comprise of approximately 20% of the world's population, producing 80% of the world's GNP, while at the same time, consuming 60% of the world's energy, Ironically, more than half of the world's population, or close to 3 billion people, have almost no access to energy services - 1.2 billion live in Asia. There is, however, enough renewable energy flow worldwide to meet all demands. Renewable energies in general now provide some 14% of the world's primary energy and is mostly covered by traditional biomass. In the field of electricity, where renewables account for 20% worldwide, it is mostly hydropower which is used as source. We need a rapid and courageous worldwide change towards an energy-efficient, Renewable Energy Systems powered energy. Asia already offers a set of successful initiatives and examples of how renewables can be promoted. Some countries have set national targets for the future share of renewable energy. Targets are an excellent strategy to demonstrate political willingness and create a stimulating investment climate for the private sector. Financing schemes, adapted to regional situations, in particular microfinance systems, demonstrate how small-scale installations of renewables could become affordable to the population.

    Uncertainty relations are studied for a characterization of topological-band insulator transitions in 2D gapped Dirac materials isostructural with graphene. We show that the relative or Kullback–Leibler entropy in position and momentum spaces, and the standard variance-based uncertainty relation give sharp signatures of topological phase transitions in these systems.

    Iran, with an average annual precipitation of about 252 mm (413 BCM) and renewable freshwater resources of 130 BCM, has irregular distribution of water resources. With a high population growth rate, agriculture remains the greatest water user in Iran but its production still does not meet the total food demand of the country. Due to unreliable water availability, the competition for water from other sectors and the increasing demand for food and better diets, Iran will experience water stress...

    A study was carried out in the Haldimand sector of Gaspé, Québec, Canada, to assess the potential link between a tight sandstone petroleum reservoir, whose potential is being evaluated, and the shallow fractured rock aquifer system. Petroleum exploration operations are taking place in the forested core of a hilly 40 km2 peninsula by the sea (up to 200 m amsl). Houses located on the periphery of the peninsula use wells for their water supply. This study served as a test case for a new framework proposed specifically to regulate oil and gas exploration and production activities. Significant concerns have been voiced in Quebec about such relatively new activities in the past few years. The study thus also aimed to provide a sound scientific perspective on the actual risk to groundwater resources related to oil and gas industry upstream activities. The study was based on the compilation of existing hydrogeological, geological and petroleum exploration data and on a field characterization. The field work involved 1) the installation of 17 observation wells and their hydraulic testing, including two fully-cored wells, 2) groundwater and surface water sampling in observation wells and more than 70 residential wells within a 2 km radius of a proposed new drill pad, and 3) geophysical logging of the open-hole observation wells. On all samples, chemical analyses involved major and minor inorganics, a wide range of organics, dissolved light hydrocarbon gases and CH4 isotopes, where present. More specialized analyses were done on observation wells (stable isotopes, tritium, 13C and 14C, noble gases, CFCs and SF6, organic acids). The hydrogeological conditions were then defined on the basis of existing and newly acquired data. Fracturing was found to control groundwater flow which is more intense in the upper 15 m of the rock aquifer. Recharge occurs on topographic highs where the rock is not covered by a low permeability glacial till, as found almost everywhere

    Full Text Available Objective – This article describes a project undertaken by the University of Wollongong Library (UWL to identify whether a correlation exists between usage of library resources and academic performance.Methods – A multidimensional approach to systems design was implemented, requiring collaboration between among the library, university administration, Performance Indicator Project team (PIP, and information technology services. The project centers on the integration and interrogation of a series of discrete datasets containing student performance, attrition, demographic, borrowing, and electronic resources usage data. PIP built a cube for the library that links usage of library resources to student demographic data and academic performance (the “Library Cube”. Other cubes will be linked later.Results – While initial reports are rudimentary and do not yet incorporate data on e-resource usage, results are favourable in demonstrating the value of using the library information resources in coursework. Based on the data generated to date, students who borrow library resources do outperform students who do not. Early trend data shows up to a 12-point difference in grades.Conclusion – The Library Cube signals a new milestone in the UWL’s quality assessment journey. Well-established measures of effectiveness and efficiency will be further complemented by measures of impact and value, allowing the library to step even closer to the goal of having effective and valued partnerships with the university community to realize teaching, learning, research, and internalization goals.

    This report provides an overview of the results of the Vital the Nicaraguan Water Resources Management Initiative, Issues process as implemented for a collaborative effort between the Nicaraguan Ministry of Environment and Natural Resources and Sandia National Laboratories. This initiative is being developed to assist in the development of an efficient and sustainable water resources management system for Nicamgua. The Vital Issues process was used to provide information for developing a project that will develop and implement an advanced information system for managing Nicaragua's water resources. Three Vital Issues panel meetings were convened to 1) develop a mission statement and evaluation criteria for identifying and ranking the issues vital to water resources management in Nicaragua 2) define and rank the vital issues; and 3) identify a preliminary list of information needed to address the vital issues. The selection of panelists from the four basic institutional perspectives- government, industiy, academe, and citizens' groups (through nongovernmental organizations (NGOs))-ensured a high level of stakeholder representation on the panels. The already existing need for a water resource management information system has been magnified in the aftemnath of Hurricane Mitch. This information system would be beneficial for an early warning system in emergencies, and the modeling and simulation capabilities of the system would allow for advanced planning. Additionally, the outreach program will provide education to help Nicaraguan improve their water hygiene practices.

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

    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.
