  1. Numerical Studies On Bubble Pump With Alternate Working Fluids

    Directory of Open Access Journals (Sweden)

    L. Bruno Augustin

    2013-10-01

    Full Text Available The importance of energy conservation in the context of growing global population and dwindling fossil fuel resources cannot be overemphasized. Energy can be conserved by using it more efficiently. The energy spent for an application should be of the correct amount and type. It would make more sense to spend heat energy for heating rather than the high grade electricity as most of the electric power in the world is generated from driving heat engines, for which heat is supplied from the combustion of fossil fuels. At the same time, depletion of these conventional resources also poses a serious problem in meeting energy requirements. In this paper, the bubble pump, which is an integral part of diffusion- absorption refrigeration system, has been investigated numerically .A thermally driven bubble pump, which can be powered by solar thermal energy, is used to lift the liquid. The bubble pump runs on solar energy and reduces the amount of energy spent by replacing the compressor in conventional vapour absorption refrigeration system. As a result of the absence of any mechanical moving part, the refrigerator is silent and very reliable in addition to an economical and environmental friendly device. The concept of such a pump is already in existence but optimization studies are yet to be extensively investigated. This paper deals with the comparison of various parameters of the bubble pump using water and Nonane as the working fluid. Numerical simulation of the bubble pump is carried out using simple numerical equations which assume slug flow in the bubble pump. The mass flow rate, the sensible heating time and position of heating element are varied and the effect it has on diameter of the pipe, pumping ratio and the heat required is studied for both the working fluids

  9. Age-sensitive effects of enduring work with alternating cognitive and physical load. A study applying mobile EEG in a real life working scenario

    Directory of Open Access Journals (Sweden)

    Edmund Wascher

    2016-01-01

    Full Text Available Ergonomic assessment of a workplace requires the evaluation of physical as well as cognitive aspects of a particular working situation. In particular the latter is hardly possible without interfering in the natural setting. Mobile acquisition of neurophysiological measures (such as parameters of the EEG may close this gap. At a simulated workplace we tracked older and younger participants with mobile EEG during a 4-5 hours work shift. They had to perform either a monotonous cognitive task, a self-paced cognitive task or a self-paced physical task in a predefined order. Self assessment, behavioral performance and spectral measures of the EEG (before most alpha power indicated that younger participants suffered from monotony. Older adults, on the other hand, were overall impaired by inefficient information processing. This was visible in EEG variations time-locked to eye blinks (blink-related synchronizations, a new measure to investigate cognitive processing in real life environments. Thus, we were able to distinguish between active and passive task-related aspects of mental fatigue without impinging on the natural working situation.

  11. Normetex Pump Alternatives Study

    Energy Technology Data Exchange (ETDEWEB)

    Clark, Elliot A.

    2013-04-25

    A mainstay pump for tritium systems, the Normetex scroll pump, is currently unavailable because the Normetex company went out of business. This pump was an all-metal scroll pump that served tritium processing facilities very well. Current tritium system operators are evaluating replacement pumps for the Normetex pump and for general used in tritium service. An all-metal equivalent alternative to the Normetex pump has not yet been identified. 1. The ideal replacement tritium pump would be hermetically sealed and contain no polymer components or oils. Polymers and oils degrade over time when they contact ionizing radiation. 2. Halogenated polymers (containing fluorine, chlorine, or both) and oils are commonly found in pumps. These materials have many properties that surpass those of hydrocarbon-based polymers and oils, including thermal stability (higher operating temperature) and better chemical resistance. Unfortunately, they are less resistant to degradation from ionizing radiation than hydrocarbon-based materials (in general). 3. Polymers and oils can form gaseous, condensable (HF, TF), liquid, and solid species when exposed to ionizing radiation. For example, halogenated polymers form HF and HCl, which are extremely corrosive upon reaction with water. If a pump containing polymers or oils must be used in a tritium system, the system must be designed to be able to process the unwanted by-products. Design features to mitigate degradation products include filters and chemical or physical traps (eg. cold traps, oil traps). 4. Polymer components can work in tritium systems, but must be replaced regularly. Polymer components performance should be monitored or be regularly tested, and regular replacement of components should be viewed as an expected normal event. A radioactive waste stream must be established to dispose of used polymer components and oil with an approved disposal plan developed based on the facility location and its regulators. Polymers have varying

    1998-09-01

    The purpose of this paper was to describe and interpret the factors that supported and maintained curricular innovation at two alternative elementary schools. The two schools have Project Adventure as their curriculum focus and use the concepts of risk, challenge, trust, cooperation, and problem solving; briefing and debriefing; and personal goal-setting contracts as part of their schoolwide curriculum (Project Adventure, 1991). Data were collected through formal interviews with the physical education teachers, the principals, and four classroom teachers at each school. Nonparticipant observation, field notes, informal interviews, and document analysis were also conducted. Inductive analysis and constant comparison were used to analyze and organize the data throughout the research process. Five factors emerged that supported the implementation of this innovative physical education program: a shared vision, external support for the schools' programs, curricula integration, centrality of physical education, and shared decision making. Project Adventure at these schools provides an example of substantive curricular reform where physical education was a critical element in the school programs. PMID:9777661

  6. Field study plan for alternate barriers

    International Nuclear Information System (INIS)

    Pacific Northwest Laboratory (PNL) is providing technical assistance in selecting, designing, evaluating, and demonstrating protective barriers. As part of this technical assistance effort, asphalt, clay, and chemical grout will be evaluated for use as alternate barriers. The purpose of the subsurface layer is to reduce the likelihood that extreme events (i.e., 100-year maximum storms, etc.) will cause significant drainage through the barrier. The tests on alternate barriers will include laboratory and field analysis of the subsurface layer performance. This field test plan outlines the activities required to test and design subsurface moisture barriers. The test plan covers activities completed in FY 1988 and planned through FY 1992 and includes a field-scale test of one or more of the alternate barriers to demonstrate full-scale application techniques and to provide performance data on a larger scale. Tests on asphalt, clay, and chemical grout were initiated in FY 1988 in small (30.5 cm diameter) tube-layer lysimeters. The parameters used for testing the materials were different for each one. The tests had to take into account the differences in material characteristics and response to change in conditions, as well as information provided by previous studies. 33 refs., 8 figs., 1 tab

    As the result of bilateral treaties to reduce the number of weapons in the nuclear stockpile, the US Department of Energy must now address the requirements for additional storage of the plutonium components (pits) from the retired weapons at Pantex until the components' final disposition. Because of the critical need to take action, Pantex has initiated two related efforts: Project Stage Right and this Staging Study. While support of Project Stage Right is a key objective of this study, the scope covers a broader range of activities and aspects of the pit staging problem. This study provides estimates of worker radiation exposures under the current scenario as well as estimated radiation exposure for workers under four alternative staging scenarios. An important objective of this study also identifies and recommends for future study other activities related to staging where radiation safety and overall efficiency can be improved.

  11. Ironmaking Process Alternative Screening Study, Volume 1

    Energy Technology Data Exchange (ETDEWEB)

    Lockwood Greene, . .

    2005-01-06

    Iron in the United States is largely produced from iron ore mined in the United States or imported from Canada or South America. The iron ore is typically smelted in Blast Furnaces that use primarily iron ore, iron concentrate pellets metallurgical coke, limestone and lime as the raw materials. Under current operating scenarios, the iron produced from these Blast Furnaces is relatively inexpensive as compared to current alternative iron sources, e.g. direct iron reduction, imported pig iron, etc. The primary problem the Blast Furnace Ironmaking approach is that many of these Blast furnaces are relatively small, as compared to the newer, larger Blast Furnaces; thus are relatively costly and inefficient to operate. An additional problem is also that supplies of high-grade metallurgical grade coke are becoming increasingly in short supply and costs are also increasing. In part this is due to the short supply and costs of high-grade metallurgical coals, but also this is due to the increasing necessity for environmental controls for coke production. After year 2003 new regulations for coke product environmental requirement will likely be promulgated. It is likely that this also will either increase the cost of high-quality coke production or will reduce the available domestic U.S. supply. Therefore, iron production in the United States utilizing the current, predominant Blast Furnace process will be more costly and would likely be curtailed due to a coke shortage. Therefore, there is a significant need to develop or extend the economic viability of Alternate Ironmaking Processes to at least partially replace current and declining blast furnace iron sources and to provide incentives for new capacity expansion. The primary conclusions of this comparative Study of Alternative Ironmaking Process scenarios are: (1) The processes with the best combined economics (CAPEX and OPEX impacts in the I.R.R. calculation) can be grouped into those Fine Ore based processes with no scrap

  12. Alternative waste forms: a comparative study

    International Nuclear Information System (INIS)

    A characterization study utilizing comparative tests has been conducted to assess product inertness of alternative waste form materials, having evaluated at this point four basic product types: sintered ceramics, glass ceramics, glass and concrete. The seven specific waste form materials studied represent simulated nuclear waste loading of 5% to 100%, processed between room temperature and 12000C and subjected to characterization tests including phase analysis, microstructure, compression testing, volatility and leach testing. Significant conclusions based upon the results obtained to date are: sintered calcine waste form PW-9 does not retain Na, Mo and Cs when leached 900C and, in fact, does not remain a solid; glass and supercalcine are alike under both hydrous and hydrothermal leach conditions with glass exhibiting a greater retention of sodium and molybdenum, supercalcine having a greater retention of cesium, and both forms approximately equal in strontium retention; volatility measurements indicate that an order of magnitude decrease in volatility occurs when a calcine waste form is incorporated in a crystalline or glassy host; glass 76-68 is superior to supercalcine SPC-5B in retention of volatiles below 11000C because of the high release of Na from SPC-5B, however, as the temperature approaches or exceeds the glass melt temperature, volatile losses of the glass equal or exceed that of SPC-5B; glass 76-68 and supercalcine SPC-5B have high compressive strengths when compared to sintered PW-9 and cement products. This is apparently due to a stronger continuum bond resulting from a glassy matrix or crystalline ingrowth over a simple mechanical agglomeration of particles

    The Washoe Tribe of Nevada and California was awarded funding to complete the Washoe Tribe Alternative Energy Feasibility Study project. The main goal of the project was to complete an alternative energy feasibility study. This study was completed to evaluate “the potential for development of a variety of renewable energy projects and to conduct an alternative energy feasibility study that determines which alternative energy resources have the greatest economic opportunity for the Tribe, while respecting cultural and environmental values” (Baker-Tilly, 2014). The study concluded that distributed generation solar projects are the best option for renewable energy development and asset ownership for the Washoe Tribe. Concentrating solar projects, utility scale wind projects, geothermal, and biomass resource projects were also evaluated during the study and it was determined that these alternatives would not be feasible at this time.

  1. Alternative approach to study fusion barrier distribution

    International Nuclear Information System (INIS)

    Fusion reactions induced by heavy-ions (HIs) at around barrier energies, play an important role in nuclear physics since they enable to study the nuclei away from the valley of stability. On the other hand, heavy-ion collisions, at below and near barrier energies, provide an ideal opportunity to study quantum tunneling phenomena in systems with many degrees of freedom. In a simple model, a potential barrier for the relative motion between the interacting nuclei is created by the strong interplay of the repulsive Coulomb and the attractive nuclear force. It has, now, been well recognized that heavy-ion collisions at energies around the Coulomb barrier are strongly affected by the internal structure of interacting nuclei. The couplings of the relative motion to the intrinsic degrees of freedom (such as collective inelastic excitations of the colliding nuclei and/or transfer processes) replaced a single potential barrier to a number of distributed barriers, leading to the enhancement in heavy ion fusion cross sections at energies near and below the Coulomb barrier than those expected from single one-dimensional barrier

  2. Lithic studies: an alternative approach to Neolithization

    Full Text Available Most models of Neolithization of the Balkans have focused on pottery, with little attention paid to other aspects of material culture. A distinctive feature of the Early Neolithic Karanovo I culture of Bulgaria is a flint industry characterized by ‘macroblade’ technology and widespread use of ‘Balkan Flint’ in conjunction with formal toolkits. The origins of this technology and the associated raw material procurement system are still unresolved. Balkan flint also occurs in Early Neolithic contexts outside the Karanovo I culture area, notably in the southern Balkans (Turkish Thrace and in the lower Danube catchment (Carpathian Basin, Iron Gates, southern Romania and northern Bulgaria. The only securely identified outcrops of Balkan flint are in the Upper Cretaceous Mezdra Formation in the Pleven-Nikopol region of northern Bulgaria. One of the most challenging aspects of the Neolithization debate is to accommodate the evidence provided by lithic studies. Among outstanding questions are: (i was Balkan flint used by the first (‘pre-Karanovo’ Neolithic communities in Bulgaria; (ii what role did Balkan flint play in the Neolithization of Southeast Europe; (iii did access to Balkan flint result in the emergence of a new laminar technology; (iv how did the Early Neolithic Balkan flint exchange network compare to that based on obsidian, which developed in and around the Aegean Basin; and (iv what and where were the origins of the Balkan flint network and the formal tools associated with it?

  4. Techno-economic study of different alternatives for biodiesel production

    International Nuclear Information System (INIS)

    Biodiesel has become an attractive diesel fuel substitute due to its environmental benefits since it can be made from renewable resource. However, the high costs surrounding biodiesel production remains the main problem in making it competitive in the fuel market either as a blend or as a neat fuel. More than 80% of the production cost is associated with the feedstock itself and consequently, efforts are focused on developing technologies capable of using lower-cost feedstocks, such as recycled cooking oils and wastes from animal or vegetable oil processing operations. The main issue with spent oils is the high level of free fatty acids found in the recycled materials. The conventional technology employs sodium methoxide as a homogeneous base catalyst for the transesterification reaction and illustrates the drawbacks in working with feedstocks that contain high levels of free fatty acids. On the other hand, homogeneous acidic catalysts are being used for exactly such feedstocks. Both acid and basic homogeneous catalyzed processes require downstream purification equipment to neutralize the catalyst and to purify the biodiesel as well as the glycerol. Recent studies have been conducted to employ heterogeneous catalysts, such acidic or basic solid resins, or immobilized lipases. These catalysts will allow the use of different feedstocks that will permit operation at lower investment costs and will require less downstream process equipment. A conceptual design of these alternative production plants has been done with a techno-economic analysis in order to compare these alternatives. A process simulator was employed to carry out the conceptual design and simulation of each technology. Using these models it was possible to analyze different scenarios and to evaluate productivity, raw material consumption, economic competitiveness, and environmental impacts of each process.

  5. A study of alternative splicing in the pig

    Jørgensen Claus B

    2010-05-01

    Full Text Available Abstract Background Since at least half of the genes in mammalian genomes are subjected to alternative splicing, alternative pre-mRNA splicing plays an important contribution to the complexity of the mammalian proteome. Expressed sequence tags (ESTs provide evidence of a great number of possible alternative isoforms. With the EST resource for the domestic pig now containing more than one million porcine ESTs, it is possible to identify alternative splice forms of the individual transcripts in this species from the EST data with some confidence. Results The pig EST data generated by the Sino-Danish Pig Genome project has been assembled with publicly available ESTs and made available in the PigEST database. Using the Distiller package 2,515 EST clusters with candidate alternative isoforms were identified in the EST data with high confidence. In agreement with general observations in human and mouse, we find putative splice variants in about 30% of the contigs with more than 50 ESTs. Based on the criteria that a minimum of two EST sequences confirmed each splice event, a list of 100 genes with the most distinct tissue-specific alternative splice events was generated from the list of candidates. To confirm the tissue specificity of the splice events, 10 genes with functional annotation were randomly selected from which 16 individual splice events were chosen for experimental verification by quantitative PCR (qPCR. Six genes were shown to have tissue specific alternatively spliced transcripts with expression patterns matching those of the EST data. The remaining four genes had tissue-restricted expression of alternative spliced transcripts. Five out of the 16 splice events that were experimentally verified were found to be putative pig specific. Conclusions In accordance with human and rodent studies we estimate that approximately 30% of the porcine genes undergo alternative splicing. We found a good correlation between EST predicted tissue

  8. Study of an alternative system for manganese bath efficiency determination

    International Nuclear Information System (INIS)

    An alternative irradiation system, using radioisotope neutron sources and a small MnSO4 solution volume, was proposed m this work to determine the Manganese Bath System (MBS) efficiency. The irradiation system was characterized through simulations with the MCNP radiation transport code from the modeling of 252Cf(f,n) and 238PuBe(alpha,n) neutron sources in several MnSO4 solution volumes and different neutron reflector medium for this solution. The parameter calculated in the simulations was the manganese neutron specific capture (MNSC), which is related to the MnSO4 solution specific activity. From the proposed systems for 252Cf (f, n) and 238PuBe (alpha,n) the NSCM was increased hundred times, in relation with that achieved in the LN/LNMRI/IRD MBS system simulation when irradiated by each these neutron sources. During study for irradiation system characterization its concept was verified using a assemble of test irradiation (ATI), which were spherical glass cavities, with few centimeter in radius, filled with MnSO4 solution, with and without presence of a neutron reflector medium. These TIA were used in four efficiency measurements and the average value was obtained. (author)

    Full Text Available Job satisfaction plays an important role on having sustainable growth in any business units. When an unsatisfied employee leaves, the business unit not only loses an employee but also it loses an intangible asset. Therefore, it is necessary to evaluate overall job satisfaction occasionally and provide some guidelines for improving work conditions. The proposed study of this paper uses five questionnaires, which are associated with job motivation, job satisfaction and organizational commitment. We have selected 25 sample employees who work for the case study of this research located in west region on Iran. Using some statistical tests we analyze the data and the preliminary results indicate that employee have an average job satisfaction. The results indicate that there are some positive relationships between job satisfaction and other factors including wage increase, psychological needs, physical equipments, entertainment equipment and work-team.

  12. Project on Alternative Systems Study - PASS. Final report

    International Nuclear Information System (INIS)

    Alternative repository systems for deep disposal of spent fuel and different types of canisters are studied regarding technical aspects in Project on Alternative System Study (PASS). The objective is to present a ranking of repository systems as well as of canister types for each system. The studies and compared systems are: KBS-3, Medium Long Tunnels (MLH), Long tunnels (VLH) and Deep Boreholes (VDH). For KBS-3 and MLH five canister types are compared (copper/steel, copper/lead, copper (HIP), steel/lead and steel), for VLH two types (copper/steel and steel), and for VDH three types (titanium/concrete with non-consolidated fuel assemblies, titanium/concrete with consolidated assemblies and copper (HIP) with non-consolidated assemblies). The comparison is separated into three sub-comparisons (Technology, Long-term performance and safety, and Costs), which eventually are merged into one ranking. With respect to canister alternatives the result is that the copper/steel canister is ranked first for KBS-3, MLH and VLH, while the titanium/concrete canister is ranked first for VDH (non-consolidated as well as consolidated assemblies. With these canister alternatives the merged ranking of repository systems results in placing KBS-3 slightly in front of MLH. VLH comes thereafter and VDH last. (32 refs.)

  14. System study of alternative waste management techniques: Final report

    International Nuclear Information System (INIS)

    This report summarizes the important results achieved in conjunction with the Research and Development Priority ''Alternative Waste Management Techniques'' sponsored by the Federal Ministry of Research and Technology from 1981 to 1984. The subject of these studies was solely ''direct disposal'' of spent fuel elements. For this purpose a reference concept was selected from a variety of possible processes and engineered in detailed form by firms in the nuclear industry. Those who worked on the engineering concepts consider this waste management method technically feasible. Several disposal casks have been fabricated. The basic licensability of direct disposal can be evaluated on the basis of the documentation developed by the companies. The direct disposal method was compared with the ''integrated waste management concept'' using reference fuel cycles with respect to the following criteria: radiological safety and nuclear material safeguards and, in addition, economic and energy-policy aspects. It was found that with respect to radiological safety, including the long-term safety of the final repository, there are no significant differences between the two fuel cycles with and without reprocessing. With respect to the nuclear material safeguards of a final repository containing spent fuel elements, there are still a number of unanswered questions. From an economic standpoint, direct disposal will be more economical in the foreseeable future than integrated waste management. Quantification of the effects of one or the other waste management method on the national economy is not necessarily possible. Reprocessing is supported primarily by technological and energy-policy considerations. On the basis of the results, the conclusion is reached that reprocessing should be pursued further, but that at the same time direct disposal should be developed to the point of practical maturity

    The perirhinal cortex (PRh) is strategically located between the neocortex and memory-related structures such as the entorhinal cortex and the hippocampal formation. The pattern of strong reciprocal connections between these areas, together with experimental evidence that PRh damage induces specific memory deficits, has placed this cortical region at the center of a growing interest for its role in learning and memory mechanisms. The aim of the present study is to clarify the involvement of PRh in learning and retention in a novel experimental model of spatial working memory, the water T-maze. The data show that pre-acquisition neurotoxic PRh lesions caused task-learning deficits. This impairment was observed during the acquisition phase as well as the retrieval phase. On the other hand, a post-acquisition PRh neurotoxic lesion failed to impair the acquisition and the retrieval of the water T-maze task performed 32 day after lesion. These results suggest a possible key role of PRh in the acquisition but not in the retention of a working memory task. Furthermore, these results show that the water T-maze may be a suitable learning paradigm to study different components of learning and memory. PMID:22391121

    2003-01-01

    The aim of the work was to identify the key factors involved in the use of alternate spectrum in various bands for a future integrated CNS data link. The study focused on systems and spectral bands that can deliver VDL-or-higher data rates in a two-way communication setting (including air-ground, ground-air, and air-air modes of operation), with multiple platforms (aircraft) operating in the same local environment. We begin with a review of the initial task list, and the final task list. The final task list contained a focus upon spectral availability and related systems that could be affected by the deployment of a new aviation data link (ADL) system. Most of this addresses the lower few layers of the communications protocol stack. A brief review of current related efforts in the aeronautical community is then provided, in which we describe several systems and programs of interest. Participation in some of these efforts is recommended. We also delineate several of the advantages and disadvantages of these system/efforts, in view of anticipated requirements of a new ADL. Desired attributes of a new ADL system are then discussed, and a connection with existing systems is made. The need to consider a wider set of alternative systems and technologies is described, and the beneficial aspects of a particular transmission technique- spread spectrum-are discussed. We then discuss in more detail several potential spectral regions, in terms of propagation conditions, available technology, spectrum availability, and waveform selection. Some comments on the need for standardization are also provided. We note that none of the existing systems described will likely meet the full range of desired features of a new ADL, but that several systems and spectral regions offer promise in terms of one or more characteristics. A system design and analysis approach is then provided. In this, we again focus on the lower few layers of the protocol stack, and aim to capture the main features

    Reasons for the use of physiological methods of assessment in addition to classical work study methods are given for the case of manual work. A study of use of both assessment processes with regard to a series of forestry tasks is presented. Poor correlations between physiological and work study assessments were obtained and since the tasks were manual in nature it was presumed the physiological methods offered greater accuracy. A test study was used to support this view. Finally, the paper suggests a physiological index of manual effort, related to individual capacity, which might be capable of application in normal field work. PMID:15677240

    Alternating copolymers are expected to exhibit a rich transition behavior in selective solvents with implications in biology and the design of thermo and pH-sensitive materials. We studied transitions of model alternating copolymers of the type (AAA...)n1(BBB...)n2, in selective solvents by MC simulations. Results showed that the eminent factor, controlling response to external stimuli, is co-polymer's chemical composition.. We focused on the extreme case of a single polymer chain of N = 1000 units, distributed equally in alternate blocks of n1= n2 =100 units (A- and B- blocks). The solvent was quite selective, i.e. good for 5 100-A-blocks, whereas the 5 100 B-blocks were quite insoluble. An extended critical region, characterized by the presence of several distinct intermediate states between coil and globules, and by fluctuations strong enough to induce spontaneous transitions among these states was observed. Our findings underline that in the case of strong blockiness the alternating architecture induces collapse transitions that proceed through stages not existing in the analogous homopolymer and di-block copolymer transitions.

  20. B cell remote-handled waste shipment cask alternatives study

    International Nuclear Information System (INIS)

    The decommissioning of the 324 Facility B Cell includes the onsite transport of grouted remote-handled radioactive waste from the 324 Facility to the 200 Areas for disposal. The grouted waste has been transported in the leased ATG Nuclear Services 3-82B Radioactive Waste Shipping Cask (3-82B cask). Because the 3-82B cask is a U.S. Nuclear Regulatory Commission (NRC)-certified Type B shipping cask, the lease cost is high, and the cask operations in the onsite environment may not be optimal. An alternatives study has been performed to develop cost and schedule information on alternative waste transportation systems to assist in determining which system should be used in the future. Five alternatives were identified for evaluation. These included continued lease of the 3-82B cask, fabrication of a new 3-82B cask, development and fabrication of an onsite cask, modification of the existing U.S. Department of Energy-owned cask (OH-142), and the lease of a different commercially available cask. Each alternative was compared to acceptance criteria for use in the B Cell as an initial screening. Only continued leasing of the 3-82B cask, fabrication of a new 3-82B cask, and the development and fabrication of an onsite cask were found to meet all of the B Cell acceptance criteria

    1982-02-01

    The possible association between selected cancers and polluted work places has been studied in a hospital-based, case-control study. By dividing all jobs in the participants working career into "polluted" and "clean", a crude measure for the total industrial exposure a worker experiences throughout his life was established. Among 103 age-matched, case-control pairs the overall estimated relative risk (RR) for exposed subjects (greater than or equal to 10 years in a polluted work place) of developing cancer compared to nonexposed (less than 10 years in a polluted work place) was 1.1. The only subgroup where a significant difference was found between the cases and the controls was the lung cancer subgroup (RR = 4.0, p = 0.02, two-tailed). When the 30 lung cancer cases were compared to an alternative control group consisting of 60 subjects matched for age and smoking habits, an estimated RR of 4.5 was found. A moderate, but not significant association between lung cancer and definite asbestos exposure was also found (RR: 2.3). As most workers are exposed to a variety of industrial agents throughout their working careers, further development of methods for characterizing combined exposures are needed, both for retrospective and prospective purposes.

  4. Alternative Energy Science and Policy: Biofuels as a Case Study

    Science.gov (United States)

    Ammous, Saifedean H.

    This dissertation studies the science and policy-making of alternative energy using biofuels as a case study, primarily examining the instruments that can be used to alleviate the impacts of climate change and their relative efficacy. Three case studies of policy-making on biofuels in the European Union, United States of America and Brazil are presented and discussed. It is found that these policies have had large unintended negative consequences and that they relied on Lifecycle Analysis studies that had concluded that increased biofuels production can help meet economic, energy and environmental goals. A close examination of these Lifecycle Analysis studies reveals that their results are not conclusive. Instead of continuing to attempt to find answers from Lifecycle Analyses, this study suggests an alternative approach: formulating policy based on recognition of the ignorance of real fuel costs and pollution. Policies to combat climate change are classified into two distinct approaches: policies that place controls on the fuels responsible for emissions and policies that target the pollutants themselves. A mathematical model is constructed to compare these two approaches and address the central question of this study: In light of an ignorance of the cost and pollution impacts of different fuels, are policies targeting the pollutants themselves preferable to policies targeting the fuels? It is concluded that in situations where the cost and pollution functions of a fuel are unknown, subsidies, mandates and caps on the fuel might result in increased or decreased greenhouse gas emissions; on the other hand, a tax or cap on carbon dioxide results in the largest decrease possible of greenhouse gas emissions. Further, controls on greenhouse gases are shown to provide incentives for the development and advancement of cleaner alternative energy options, whereas controls on the fuels are shown to provide equal incentives to the development of cleaner and dirtier

    Full Text Available Purpose: The most popular alternative systems to mass production at an academic level (lean manufacturing, agile manufacturing, flexible customization, mass customization... share many characteristics. Our article identifies an extensive set of alternative practices to mass production; analyzes the classification of practices in categories (Flow, TQM, TPM, Customer Relations, Supplier Relations and Human Resources Practices and analyzes the impact on several human performance indicators such as satisfaction, absenteeism, voluntary turnover, permanent contracts, knowledge, personal & social adjustment activities and integration of workers into ordinary companies. Design/methodology/approach: Survey in sheltered work centers. We use regression analysis in order to prove relations between explicative and criterion variables. Findings: The results of our research allow us to identify that human resource management and customer relationship practices have significant effects on job satisfaction, knowledge, integration into ordinary companies and personal and social adjustment. Research limitations/implications: Data came only from one industry; therefore the results would not be directly generalized to other contexts. Practical implications: Managers in Sheltered work centers can estimate the impact of the deployment of alternative tools to mass production. Originality/value: There are few papers relating lean manufacturing tools and human resources performance indicators. At the same time, there are very few research carried out in sheltered work centers context.

  9. Endocrine mediation of vertebrate male alternative reproductive tactics: the next generation of studies.

    Science.gov (United States)

    Knapp, Rosemary

    2003-11-01

    In many species of animals, males may achieve reproductive success via one of several alternative reproductive tactics. Over the past decade or so, there has been a concerted effort to investigate endocrine mechanisms that underlie such discrete behavioral (and often morphological) variation. In vertebrates, the first generation of studies focused on potential organizational or activational effects of steroid hormones (Moore, 1991; Moore et al., 1998). Some of these studies have made it clear that, in addition to circulating hormone levels, one must also consider other aspects of the endocrine system, including hormone receptors, binding globulins and potential interactions among endocrine axes. In this paper, I review recent work on endocrine mechanisms and suggest possibilities for future investigation. I highlight how individual variation in sensitivity to environmental conditions, particularly with respect to various stressors, may account for the existence of alternative male reproductive phenotypes. Along these lines, I briefly explain the logic behind our work with male phenotypes of longear sunfish (Lepomis megalotis) that is aimed at determining the tissue-specific distribution and activity of two enzymes that are common to androgen and glucocorticoid metabolism. A major goal of our work is to examine the potential role of steroidogenic enzymes in the transduction of environmental information to influence the expression of alternative male reproductive phenotypes.

    The simplest response to the title of this paper is that the measures that are commonly employed in evaluating prospective graduate and professional students don’t work. That is, scores from the Graduate Record Examination (GRE) and prior grades (GPA) appear to have little validity in assessing postbaccalaureate student potential (Sternberg & Williams, 1997; Sedlacek, 1998, 2004; Bair & Haworth, 1999). Measurement problems such as restriction of range will discussed and the need to consider a multiverse statistical model presented. An alternative assessment system based on noncognitive variables will be presented and examples of its use with graduate and professional students discussed (Sedlacek, 2004, 2012, in press).

    1980-01-01

    The potential technical capabilities of energy conversion systems in the 1985 - 2000 time period were defined with emphasis on systems using coal, coal-derived fuels or alternate fuels. Industrial process data developed for the large energy consuming industries serve as a framework for the cogeneration applications. Ground rules for the study were established and other necessary equipment (balance-of-plant) was defined. This combination of technical information, energy conversion system data ground rules, industrial process information and balance-of-plant characteristics was analyzed to evaluate energy consumption, capital and operating costs and emissions. Data in the form of computer printouts developed for 3000 energy conversion system-industrial process combinations are presented.

    Certain workplaces are called jobs with limited tenure. Due to physical or psychosocial risk factors, often coupled with qualification mismatches, workers cannot grow old in them. That may lead to premature exit into retirement, to a period of drawing a work incapacity pension or to a long spell of unemployment. A horizontal career change, which enables the worker to move on to a less burdening workplace while preserving social status, is a possible solution. The objective of the "Horizontal career change-a new job opportunity for older employees" project is to develop a model of career changes for workers employed in jobs with limited tenure and to implement it in the form of an information- and communication technology-based tool. Possible applications range from individual career planning, through institutionalized vocational reintegration, to personnel development in small and medium-sized enterprises. PMID:24629881

    2012-05-01

    Full Text Available Water scarcity is an issue of worldwide concern since it is already having an impact on social development. Mexico is not an exception to this problem because in several regions of the country are great difficulties in supplying water, primarily for agricultural use. In Sinaloa, it had been mentioned repeatedly by the media that in the Irrigation District 063, located in the northern of the state, there are problems of water scarcity, and yet there still exist difficulties in conserving the resource. More than 49% of the water used for agriculture is wasted. To resolve this problem, producers and government agencies spend significant resources for investment in water conservation. However, the results have not been entirely satisfactory because the waste is high, a situation that motivates them to study more deeply the main weaknesses that affect sustainable resource use. Farmer’s participation in the administration of water infrastructure is important, as well as providing financial resources for the conservation of water system; and participation in activities of construction and repaired of water infrastructure. Farmer’s should also plan and design strategies for water conservation. This situation requires an appropriate level of technology and intellectual, rather than local producers and thus no complicated sustainable resource management. That is what local producers don’t have and therefore it complicates the sustainable management of the resource.

    The Advanced Transportation System Studies alternate propulsion subsystem concepts propulsion database interim report is presented. The objective of the database development task is to produce a propulsion database which is easy to use and modify while also being comprehensive in the level of detail available. The database is to be available on the Macintosh computer system. The task is to extend across all three years of the contract. Consequently, a significant fraction of the effort in this first year of the task was devoted to the development of the database structure to ensure a robust base for the following years' efforts. Nonetheless, significant point design propulsion system descriptions and parametric models were also produced. Each of the two propulsion databases, parametric propulsion database and propulsion system database, are described. The descriptions include a user's guide to each code, write-ups for models used, and sample output. The parametric database has models for LOX/H2 and LOX/RP liquid engines, solid rocket boosters using three different propellants, a hybrid rocket booster, and a NERVA derived nuclear thermal rocket engine.

    1994-09-30

    The Waste Receiving and Processing Module 1 Facility is designed to examine, process, certify, and ship drums and boxes of solid wastes that have a surface dose equivalent of less than 200 mrem/h. These wastes will include low-level and transuranic wastes that are retrievably stored in the 200 Area burial grounds and facilities in addition to newly generated wastes. Certification of retrievably stored wastes processing in WRAP 1 is required to meet the waste acceptance criteria for onsite treatment and disposal of low-level waste and mixed low-level waste and the Waste Isolation Pilot Plant Waste Acceptance Criteria for the disposal of TRU waste. In addition, these wastes will need to be certified for packaging in TRUPACT-II shipping containers. Characterization of the retrievably stored waste is needed to support the certification process. Characterization data will be obtained from historical records, process knowledge, nondestructive examination nondestructive assay, visual inspection of the waste, head-gas sampling, and analysis of samples taken from the waste containers. Sample characterization refers to the method or methods that are used to test waste samples for specific analytes. The focus of this study is the sample characterization needed to accurately identify the hazardous and radioactive constituents present in the retrieved wastes that will be processed in WRAP 1. In addition, some sampling and characterization will be required to support NDA calculations and to provide an over-check for the characterization of newly generated wastes. This study results in the baseline definition of WRAP 1 sampling and analysis requirements and identifies alternative methods to meet these requirements in an efficient and economical manner.

    In heat assisted magnetic recording (HAMR), optical near field transducer (NFT) is a key component. Au is currently used as NFT material because of its strong surface plasmon effect. Due to the soft property of Au material, reliability of Au NFT becomes a key issue for realizing HAMR production. In this paper, the possibility of alternative materials, including transition metal nitrides (TMNs) and transparent conducting oxides (TCOs) to replace Au is studied. The results show that all of the listed TMN and TCO materials can meet the mechanical requirements at room temperature in terms of hardness and thermal expansion. An optical model, which includes optical waveguide, NFT and FePt media, is used to simulate NFT performances. The results indicate that the resonant wavelengths for NFT with TCO materials are longer than 1500 nm, which is not suitable for HAMR application. TMN materials are suitable for NFT application at wavelength band of around 800 nm. But the NFT efficiency is very low. ZrN is the best material among TMN materials and the efficiency of ZrN NFT is only 13% of the Au NFT's efficiency. Reducing refractive index (n) and increasing extinction coefficient (k) will both lead to efficiency increase. Increasing k contributes more in the efficiency increase, while reducing n has a relatively low NFT absorption. For materials with the same figure of merit, the NFT with larger k material has higher efficiency. Doping materials to increase the material conduction electron density and growing film with larger size grain may be the way to increase k and reduce n.

    In the future, there will be a need for constant cargo launches from Earth to Mars in order to build, and then sustain, a Martian base. Currently, chemical rockets are used for space launches. These are expensive and heavy due to the amount of necessary propellant. Nuclear thermal rockets (NTRs) are the next step in rocket design. Another alternative is to create a launcher on the lunar surface that uses magnetic levitation to launch cargo to Mars in order to minimize the amount of necessary propellant per mission. This paper investigates using nuclear power for six different cargo launching alternatives, as well as the orbital mechanics involved in launching cargo to a Martian base from the moon. Each alternative is compared to the other alternative launchers, as well as compared to using an NTR instead. This comparison is done on the basis of mass that must be shipped from Earth, the amount of necessary propellant, and the number of equivalent NTR launches. Of the options, a lunar coil launcher had a ship mass that is 12.7% less than the next best option and 17 NTR equivalent launches, making it the best of the presented six options.

    Mommaerts, Jean-Luc; Devroey, Dirk

    2013-01-01

    In this article, a "healing method" (HM) is defined as any method intended to improve health through non-somatic means. For many healing methods, especially within the realm of complementary and alternative medicine (CAM), there is mounting debate over the question "Does it work?" Indeed, this seems to be the primary question for most stakeholders. Yet in light of the well-documented effects of nonspecific factors, particularly empathy and placebo (EP), we contend that the basic question is: "What is 'it'?" Without answering this question, scientific progress is impossible, and research costs will spiral upwards without producing tangible results. Furthermore, it is impossible to characterize the potential side effects of healing methods without a full understanding of the underlying mechanisms through which they act. It is generally acknowledged that many healing methods are sociohistorical artifacts, based on underlying theoretical models that are divorced from established science. There is a need for healing method research that is accommodating of such methods' fluid nature while being congruent with accepted scientific practices. "It works" is no longer an adequate justification for any healing method, as "it" often turns out to be a combination of nonspecific factors. PMID:23974507

    The purpose of this document is to discuss issues related to the implementation of each of the five down-selected INEEL/INTEC radioactive liquid waste (sodium-bearing waste - SBW) treatment alternatives and summarize information in three main areas of concern: process/technical, environmental permitting, and schedule. Major implementation options for each treatment alternative are also identified and briefly discussed. This report may touch upon, but purposely does not address in detail, issues that are programmatic in nature. Examples of these include how the SBW will be classified with respect to the Nuclear Waste Policy Act (NWPA), status of Waste Isolation Pilot Plant (WIPP) permits and waste storage availability, available funding for implementation, stakeholder issues, and State of Idaho Settlement Agreement milestones. It is assumed in this report that the SBW would be classified as a transuranic (TRU) waste suitable for disposal at WIPP, located in New Mexico, after appropriate treatment to meet transportation requirements and waste acceptance criteria (WAC).

  1. Study on ultra-precision magnetic abrasive finishing process using low frequency alternating magnetic field

    International Nuclear Information System (INIS)

    We proposed a new ultra-precision magnetic abrasive finishing (MAF) process using low frequency alternating magnetic field in this paper. Magnetic cluster themselves may produce the up and down movement change under alternating magnetic force. The movement may not only promote the dispersion of micro-magnetic particles, but also improve stirring effect and cross-cutting effects of the abrasives, achieving circulation and update to ensure the stability of grinding tools. This process is considered to be able to efficiently apply in ultra-precision finishing of plane and complicated micro-surfaces. In this study, we investigated the effects of alternating magnetic field on magnetic field distribution, finishing force and abrasive behavior. Furthermore, a set of experimental devices have been designed for finishing SUS304 stainless steel plate. The present work is aimed at understanding finishing particularity of this process and studying impacts of important process parameters namely grinding fluid, rotational speed of magnetic pole, current frequency on change in finish surface and material removal. Experimental results indicate that the process can realize ultra-precision finishing of plane by using oily grinding fluid. In the present research, the surface roughness of SUS304 stainless steel plate was improved from 240.24 nm to 4.38 nm by this process. - Highlights: • We investigated magnetic field distribution in processing region. • Magnetic cluster can produce a fluctuating finishing force in alternating magnetic field. • Oily grinding fluid is more applicable to this process. • Few nanometer finish surface can be obtained by this process

    Wiersma, B.

    2010-09-29

    Due to the need to close High Level Waste storage tanks, chemical cleaning methods are needed for the removal of sludge heel materials remaining at the completion of mechanical tank cleaning efforts. Oxalic acid is considered the preferred cleaning reagent for heel dissolution of iron-based sludge. However, the large quantity of chemical reagents added to the tank farm from oxalic acid based cleaning has significant downstream impacts. Optimization of the oxalic acid cleaning process can potentially reduce the downstream impacts from chemical cleaning. To optimize oxalic acid usage, a detailed understanding of the chemistry of oxalic acid based sludge dissolution is required. Additionally, other acidic systems may be required for specific waste components that have low solubility in oxalic acid, and as a means to reduce oxalic acid usage in general. Electrochemical corrosion studies were conducted with 1 wt. % oxalic acid at mineral acid concentrations above and below the optimal conditions for this oxalic acid concentration. Testing environments included pure reagents, pure iron and aluminum phases, and sludge simulants. Mineral acid concentrations greater than 0.2 M and temperatures greater than 50 C result in unacceptably high corrosion rates. Results showed that manageable corrosion rates of carbon steel can be achieved at dilute mineral acid concentrations (i.e. less than 0.2 M) and low temperatures based on the contact times involved. Therefore, it is recommended that future dissolution and corrosion testing be performed with a dilute mineral acid and a less concentrated oxalic acid (e.g., 0.5 wt.%) that still promotes optimal dissolution. This recommendation requires the processing of greater water volumes than those for the baseline process during heel dissolution, but allows for minimization of oxalic acid additions. The following conclusions can be drawn from the test results: (1) In both nitric and sulfuric acid based reagents, the low temperature and

    Bethune, Shirley; Schachtschneider, Klaudia

    2004-12-01

    The Spitzkoppe Community Campsite in western Namibia lies in an area with very limited water resources. Water scarcity places a constraint on community income generation and development opportunities. The existing water resources are overexploited and to ensure future water security, the community must take sustainable water management into consideration in their daily lives and business ventures, including tourism. This has been successfully achieved at the Spitzkoppe Community Campsite through a combination of high community motivation, organisation and action, the involvement of researchers and trainers in water resource management and support from developers. The most appropriate water management solutions were found through ongoing practical testing of different strategies and technologies over two years. This paper presents a case study of a community-based tourist camp at Spitzkoppe and traces the community's progress towards developing an alternative way to combat desertification and a potentially lucrative tourist business.

  6. Using biofuel tracers to study alternative combustion regimes

    2007-06-01

    Interest in the use of alternative fuels and engines is increasing as the price of petroleum climbs. The inherently higher efficiency of Diesel engines has led to increased adoption of Diesels in Europe, capturing approximately 40% of the new passenger car market. Unfortunately, lower CO2 emissions are countered with higher nitrogen oxides (NOx) and particulate matter (PM) emissions and higher noise. Adding oxygenated compounds to the fuel helps reduce PM emissions. However, relying on fuel alone to reduce PM is unrealistic due to economic constraints and difficult due to the emerging PM standards. Keeping peak combustion temperature below 1700 K inhibits NOx formation. Altering the combustion regime to burn at temperatures below the NOx threshold and accept a wide variety of fuels seems like a promising alternative for future engines. Homogeneous charge compression ignition (HCCI) is a possible solution. Fuel and air are well mixed prior to intake into a cylinder (homogeneous charge) and ignition occurs by compression of the fuel-air mixture by the piston. HCCI is rapid and relatively cool, producing little NOx and PM. Unfortunately, it is hard to control since HCCI is initiated by temperature and pressure instead of a spark or direct fuel injection. We investigate biofuel HCCI combustion, and use intrinsically labeled biofuels as tracers of HCCI combustion. Data from tracer experiments are used to improve our combustion modeling.

  7. Study on alternatives of inertisation of nuclear power plant containment

    International Nuclear Information System (INIS)

    In the course of a severe accident in a nuclear power plant, the hydrogen generation and other flammable gases, during the core degradation phase and the interaction corium-concrete, could produce the failure of the containment by overpressure of by combustion. According to the analysis of the potential effects of hydrogen evolution, following accidents inside the containment trough a Defense-in depth principle, which attempts to assure that the containment must not fail catastrophically, two techniques have been evaluated: a: Inertisation pre-accident and b: Inertisation post-accident. The technique of inertisation pre-accident consists in replacing the air of the containment with inert-gas like nitrogen (N2) or carbon dioxide (CO2) during the normal operation. The inertisation post-accident in combination with early venting system consists in replacing the air of the containment with inert-gas like nitrogen (N2) or carbon dioxide (CO2), immediately after the beginning of the accident, while the radioactivity is still negligible inside the containment. A system of inertisation pre-accident with nitrogen is used on BWR Mark I and Mark II. Investigations on the inertisation post-accident of the containment atmosphere during severe accidents have been carried out with different objectives from principles of the decade of 1980. Studies concerning hydrogen problem for the nuclear power plants Atucha I and CAREM-25 have permitted to know that the hydrogen generation during an accidental sequence with core degradation, would result important, being able to arrive to form explosive mixtures. In the present work, the applicability of the techniques of inertisation is analyzed for the containment of the Atucha I and CAREM-25, considering the particular design characteristics of these plants.

  9. Study on the improvement of working environment at night in maintenance works at nuclear power plants

    International Nuclear Information System (INIS)

    At the maintenance work site in nuclear power plants, due to the shortening (reduction of a regular inspection period) of the regular inspection period, the tendency toward working on around-the-clock basis has increased; thus, nighttime work is on the rise. Based upon research both locally and internationally, as well as examples of measures against such a tendency and the results of on-site surveys of the environment surrounding maintenance works at nuclear power plants, the author comprehensively studied the effects of nighttime work on workers, the measures to cope with the situation, and how a working environment for nighttime work should be. Based on the results, the authors made a guidebook for nighttime maintenance work at nuclear power plants. This guidebook, which deals with the subject of nighttime maintenance work at nuclear power plants, is quite unique in the world. It is expected that by using this guidebook, the quality of nighttime maintenance work and the levels of techniques/skills would be enhanced and maintained, and the safety of workers would be ensured, promoting considerably thus the establishment of a comfortable workplace.

  10. Digital High Speed Interconnects: A Study Of The Optical Alternative

    Science.gov (United States)

    Hartman, Davis H.

    1986-10-01

    The use of optics as an alternative method for achieving very high speed (10 Gb/s > bit rate > 500 Mb/s) electrical interconnects is the subject of this paper. Optical interconnect media considered include plastic channel waveguides, glass waveguides, fibers, and free-space interconnects. Typical interconnection distances considered are inches or less. The problems of cou-pling and interconnecting and their overall effect on system power budgets are also discussed. As a means of quantifying the results, link budgets for a 565 Mb/s, a 2.3 Gb/s, and a 4.6 Gb/s interconnect scenario are made. Multipoint as well as single-point-to-single-point situations are considered.

  11. Using Biofuel Tracers to Study Alternative Combustion Regimes

    Energy Technology Data Exchange (ETDEWEB)

    Mack, J H; Flowers, D L; Buchholz, B A; Dibble, R W

    2006-02-14

    Interest in the use of alternative fuels and combustion regimes is increasing as the price of petroleum climbs. The inherently higher efficiency of Diesel engines has led to increased adoption of Diesels in Europe, capturing approximately 40% of the new passenger car market. Unfortunately, lower CO{sub 2} emissions are countered with higher nitrogen oxides (NOx) and particulate matter (PM) emissions, and higher noise. Noise and PM have traditionally been the obstacles toward consumer acceptance of Diesel passenger cars in North America, while NOx (a key component in photochemical smog) has been more of an engineering challenge. Diesels are lean burning (combustion with excess oxygen) and reducing NOx to N2 in an oxygen rich environment is difficult. Adding oxygenated compounds to the fuel helps reduce PM emissions, but relying on fuel alone to reduce PM is unrealistic. Keeping peak combustion temperature below 1700 K prevents NOx formation. Altering the combustion regime to burn at temperatures below the NOx threshold and accept a wide variety of fuels seems like a promising alternative for future engines. Homogeneous Charge Compression Ignition (HCCI) is a possible solution. Fuel and air are well mixed prior to intake into a cylinder (homogeneous charge) and ignition occurs by compression of the fuel-air mixture by the piston. HCCI is rapid and relatively cool, producing little NOx and PM. Unfortunately, it is hard to control since HCCI is initiated by temperature and pressure instead of a spark or direct fuel injection. We investigate biofuel HCCI combustion, and use intrinsically labeled biofuels as tracers of HCCI combustion. Data from tracer experiments are used to validate combustion modeling.

  12. Numerical study on the effects of the alternative structure geometries on the groundwater flow at the Romuvaara site

    International Nuclear Information System (INIS)

    The work has two aims. Firstly, it completes the numerical modelling work for the groundwater flow at the Romuvaara site in Finland performed during the preliminary site investigations by varying geometries of the most significant fracture zones. The modified fracture zone geometries are selected within the uncertainties of the structure of the bedrock model. Secondly, the work studies the effects of several potential fracture zones. The locations and geometries of these zones are decided in such a way that either they offer potential or alternative hydrogeologic connections that would explain the anomalies in the results of the earlier field investigations or their existence has been implied by geophysical studies. The field results comprise the measured hydraulic head values under the natural conditions in boreholes KR1 -KRS, and the hydraulic head responses in the pumping test. The work employs the calibrated flow model developed in the preliminary site investigations as the base case, that is modified to correspond to the alternative geometries. Before the simulations with the alternative geometries, the boundary condition for the top of the flow model is partly changed in this work in order to revoke the modification motivated by incorrect field data that were used in the calibration of the flow model.

  13. Alternative cathodes based on iron phthalocyanine catalysts for mini- or micro-DMFC working at room temperature

    International Nuclear Information System (INIS)

    Iron phthalocyanine based cathodes were prepared either by dispersion of FePc on carbon or by electropolymerization of aniline in presence of FeTsPc. The macrocycles based cathodes were compared to a classical commercial Pt/C cathode in a standard three-electrode electrochemical cell and under DMFC conditions at room temperature. It was shown that the molecular dispersion of FeTsPc into a PAni film greatly enhances the activity of the macrocycle catalyst towards oxygen reduction reaction (ORR). But, in the same time, the stability under DMFC conditions is drastically decreased compared to the stability obtained with a FePc/C electrode. It was suggested that this instability of the catalytic film was rather due to the release of the FeTsPc from the polymer than to the destruction of the macrocycle active centre. Even if iron phthalocyanine catalysts display total tolerance to methanol when the anode is fed with a 5 M methanol solution, the comparison between a PAni-FeTsPc/C cathode and a Pt/C cathode in DMFC working conditions is in favor of the Pt/C cathode, in term of maximum achieved power density. However, the ratio (platinum atoms per cm2/number of FeTsPc molecules per cm2) is close to 100, which allows to be optimistic for further enhancement of activity of polymer-FeTsPc electrodes. It was suggested that researches to develop new electron conductive polymers stable under oxidative environment and with a high doping capacity could be a direction to use platinum alternative cathode catalysts in DMFC technology

    2008-01-01

    Full Text Available The paper gives an approximate method for calculation of the temperature at a final stage of fuel-air mixture burning in a closed vessel that is a combustion chamber of the internal combustion engine (ICE. The paper contains calculation of temperature values for various fuel-air mixtures, shows nature of temperature changes and presents analysis of combustion product temperature behaviour modification and analyzed the behaviour in accordance with an initial pressure in the chamber. The paper reveals the fact that a combustion temperature is increasing for all mixtures when an initial pressure in combustion chamber is increased. The hydrogen-air mixture has the highest combustion temperature among investigated mixtures and products of propane conversion have the lowest one.The Maxe-effect has been investigated in combustion of hydrogen-air mixture and design formulaes have been obtained. Calculation of temperature difference of the first and last portions of combustion products has been made with due account of the Maxe-effect.The proposed approximate method for calculation of temperatures indices in the various zones of combustion chamber in view of the Mach effect makes it possible to forecast thermodynamic nature of combustion process while using alternative engine fuels for internal combustion engine.

    2011-02-01

    Based on the idea that electric light at night might account for a portion of the high and rising risk of breast cancer worldwide, it was predicted long ago that women working a non-day shift would be at higher risk compared with day-working women. This hypothesis has been extended more recently to prostate cancer. On the basis of limited human evidence and sufficient evidence in experimental animals, in 2007 the International Agency for Research on Cancer (IARC) classified 'shift work that involves circadian disruption' as a probable human carcinogen, group 2A. A limitation of the epidemiological studies carried out to date is in the definition of 'shift work.' IARC convened a workshop in April 2009 to consider how 'shift work' should be assessed and what domains of occupational history need to be quantified for more valid studies of shift work and cancer in the future. The working group identified several major domains of non-day shifts and shift schedules that should be captured in future studies: (1) shift system (start time of shift, number of hours per day, rotating or permanent, speed and direction of a rotating system, regular or irregular); (2) years on a particular non-day shift schedule (and cumulative exposure to the shift system over the subject's working life); and (3) shift intensity (time off between successive work days on the shift schedule). The group also recognised that for further domains to be identified, more research needs to be conducted on the impact of various shift schedules and routines on physiological and circadian rhythms of workers in real-world environments.

  19. Study of greenhouse gases reduction alternatives for the exploitation of non conventional oil sands in Canada

    Energy Technology Data Exchange (ETDEWEB)

    2008-07-01

    High energy prices and greenhouse gases reduction represent the main challenges the current worldwide energetic situation has to face. As a consequence, paradox strategies can be highlighted: oil prices are sufficiently high to exploit non conventional oil resources, like extra heavy oils and oil sands. But the production of these resources emits larger GHG than the conventional oil path and implies other major environmental issues (water management, risks of soil pollution, destruction of the boreal forest), incompatible with the rules validated by the protocol of Kyoto. At the light of the new greenhouse gases reduction regulation framework announced by the Canadian Federal government, this work focuses on the study of greenhouse gases reduction alternatives applied to the non conventional oil sands exploitation in Canada.

  4. New Geographies of Work: A Case Study from Sweden

    Directory of Open Access Journals (Sweden)

    Brita Hermelin

    2012-01-01

    Full Text Available This paper describes and analyses the geography of work, i.e., the spatial patterns in where paid work is done. The geography of work may diverge from the geography of employment when paid work is done at the premises of client organizations, during commuting, on business trips, on external meetings, at home or at other places. The particular patterns in the geography of work depend on a number of factors, possibilities and constraints. The paper takes its point of departure from the debate about how structural economic changes resulting from evolving service industries and the development of Information and Communication Technology (ICT entail new forms for the organization of paid work. Flexibility, reflexivity, flows and places are key concepts. The paper presents a case study from Stockholm that takes a workplace perspective and looks at knowledge-intensive work in a public sector organization. The empirical study analyses data from interviews, time diaries and a questionnaire. We analyse how the geography of work is the result of negotiations between different parties and in different arenas, and how this spatial pattern is the result of the character of work tasks and accessibility of ICT support. The discussion illustrates a complex picture of the coexistence of spatial fix and spatial flexibility, and how this may cause tensions but also convenient solutions for organizing and conducting paid work.

    2014-12-01

    Full Text Available The aim of this paper is to analyse the work-study dilemma of Czech students. We examine the impact of the work and study workload on the student’s expectations for their future labour market chances. For the future formal evaluation of Czech students’ workload, it is necessary to take into account if the students’ jobs are closely connected to their field of study, which make up the important part of their education. We used a unique dataset based on the survey EUROSTUDENT V to test this challenging question. We have found that Czech full-time students almost one full-time employment studying and working in one workweek. It was proven, that students who study very hard as well as students with in-branch experience are optimistic about their future labour prospects. Business-minded students especially prefer working hours to studying at school or at home. We did not discover the importance of family background to their workload with the exception of the labour-market perspectives. Furthermore we found considerable differences between men and women’s work experience during their studies. Finally, according to the solution of the WSDM model, we proved that while working hours are substitutes for hours spent at school, the role of self-study is irreplaceable.

    The introduction of strategic corporate sustainability policies is expected to result in the improvement of several issues in companies. One of these issues is work, which should involve greater well-being for workers. Within the context of production engineering, this research connects sustainability and work-related issues, the latter seen in light of the discipline of ergonomics. Based on case studies conducted at four companies considered sustainability benchmarks, we examined how the introduction of the theme of sustainability has influenced work-related issues. The elements analyzed here were the corporate sustainability strategy, organizational practices for deploying the strategy, and the work design phase. The last element is the moment in which work is prescribed in the organization. The results show that, despite the announcement of the inclusion of changes in work, there is not any explicit evidence confirming that such changes are considered as a requirement for corporate sustainability projects.

    2011-01-01

    It has been repeatedly hypothesized that job characteristics are related to changes in personality in humans, but often personality models still omit effects of life experience. Demonstrating reciprocal relationships between personality and work remains a challenge though, as in humans, many other influential factors may interfere. This study investigates this relationship by comparing the emotional reactivity of horses that differed only by their type of work. Horses are remarkable animal models to investigate this question as they share with humans working activities and their potential difficulties, such as "interpersonal" conflicts or "suppressed emotions". An earlier study showed that different types of work could be associated with different chronic behavioural disorders. Here, we hypothesised that type of work would affect horses' personality. Therefore over one hundred adult horses, differing only by their work characteristics were presented standardised behavioural tests. Subjects lived under the same conditions (same housing, same food), were of the same sex (geldings), and mostly one of two breeds, and had not been genetically selected for their current type of work. This is to our knowledge the first time that a direct relationship between type of work and personality traits has been investigated. Our results show that horses from different types of work differ not as much in their overall emotional levels as in the ways they express emotions (i.e. behavioural profile). Extremes were dressage horses, which presented the highest excitation components, and voltige horses, which were the quietest. The horses' type of work was decided by the stall managers, mostly on their jumping abilities, but unconscious choice based on individual behavioural characteristics cannot be totally excluded. Further research would require manipulating type of work. Our results nevertheless agree with reports on humans and suggest that more attention should be given to work

  20. Numerical study on the effects of the alternative structure geometries on the groundwater flow at the Olkiluoto site

    International Nuclear Information System (INIS)

    In the study the effects of the alternative hydrogeologic features on the groundwater flow are numerically modelled. The studied cases comprise the hydrogeologic features that were classified as possible in the bedrock model or implied either by the new interpretations of the results of the field investigations or the numerical groundwater flow analysis in preliminary site investigations. The preliminary site investigations for the radioactive waste disposal (Olkiluoto, Finland) were completed by the end of 1992. This report is a direct continuation of the earlier modeling work, which resolved the transmissivities and boundary conditions that yielded the calculated results agreeing the results of the field studies as well as possible. In this work, six alternative geometries are studied altogether. Each geometry is studied separately. The effects of the alternative geometries are evaluated by comparing the calculated results with the results of the field investigations. The field results consist of the measured fresh water head under the natural conditions and pumping test responses. (orig.) (29 refs., 24 figs., 8 tabs.)

  2. Systems study 'Alternative Entsorgung'. Final report. Technical annex 23

    International Nuclear Information System (INIS)

    Reprocessing is not sensible for a number of certain spent fuel elements. From this point of view, it is necessary to develop a concept which takes into account the final storage of vitrified fission products and also fuel elements which are not processed. The aim of the mixed fuel processing concept is to design a method of treatment, which provides externally identical final storage barrels for both ways of fuel disposal and which provides associated standardized handling equipment. The study shows a way which provides for the packing of processed spent fuel elements in moulds with the external dimensions of the HAW mould and which makes it possible to store these fuel element final storage moulds together with HAW moulds in boreholes.

    In an effort to develop and optimize chemical cleaning methods for the removal of sludge heels from High Level Waste tanks, solubility tests have been conducted using nonradioactive, pure metal phases. The metal phases studied included the aluminum phase gibbsite and the iron phases hematite, maghemite, goethite, lepidocrocite, magnetite, and wustite. Many of these mineral phases have been identified in radioactive, High Level Waste sludge at the Savannah River and Hanford Sites. Acids evaluated for dissolution included oxalic, nitric, and sulfuric acids and a variety of other complexing organic acids. The results of the solubility tests indicate that mixtures of oxalic acid with either nitric or sulfuric acid are the most effective cleaning solutions for the dissolution of the primary metal phases in sludge waste. Based on the results, optimized conditions for hematite dissolution in oxalic acid were selected using nitric or sulfuric acid as a supplemental proton source. Electrochemical corrosion studies were also conducted (reported separately; Wiersma, 2010) with oxalic/mineral acid mixtures to evaluate the effects of these solutions on waste tank integrity. The following specific conclusions can be drawn from the test results: (1) Oxalic acid was shown to be superior to all of the other organic acids evaluated in promoting the dissolution of the primary sludge phases. (2) All iron phases showed similar solubility trends in oxalic acid versus pH, with hematite exhibiting the lowest solubility and the slowest dissolution. (3) Greater than 90% hematite dissolution occurred in oxalic/nitric acid mixtures within one week for two hematite sources and within three weeks for a third hematite sample with a larger average particle size. This dissolution rate appears acceptable for waste tank cleaning applications.

    Due to the need to close waste storage tanks, chemical cleaning methods are needed for the effective removal of the heels. Oxalic acid is the preferred cleaning reagent for sludge heel dissolution, particularly for iron-based sludge, due to the strong complexing strength of the oxalate. However, the large quantity of oxalate added to the tank farm from oxalic acid based chemical cleaning has significant downstream impacts. Optimization of the oxalic acid cleaning process can potentially reduce the downstream impacts from chemical cleaning. To optimize oxalic acid usage, a detailed understanding of the chemistry of oxalic acid based sludge dissolution is required. Additionally, other acid systems may be required for specific waste components with low solubility in oxalic acid and as a means to reduce oxalic acid usage in general. Solubility tests were conducted using non-radioactive, pure metal phases known to be the primary phases present in High Level Waste sludge. The metal phases studied included the aluminum phases gibbsite and boehmite and the iron phases magnetite and hematite. Hematite and boehmite are expected to be the most difficult iron and aluminum phases to dissolve. These mineral phases have been identified in both SRS and Hanford High Level Waste sludge. Acids evaluated for dissolution included oxalic, nitric, and sulfuric acids. The results of the solubility tests indicate that oxalic and sulfuric acids are more effective for the dissolution of the primary sludge phases. For boehmite, elevated temperature will be required to promote effective phase dissolution in the acids studied. Literature reviews, thermodynamic modeling, and experimental results have all confirmed that pH control using a supplemental proton source (additional acid) is critical for minimization of oxalic acid usage during the dissolution of hematite. These results emphasize the importance of pH control in optimizing hematite dissolution in oxalic acid and may explain the somewhat

    This study aims to gain insight in the motivational process of the Job Demands-Resources (JD-R) model by examining whether daily fluctuations in colleague support (i.e., a typical job resource) predict day-levels of job performance through self-efficacy and work engagement. Forty-four flight attendants filled in a questionnaire and a diary booklet before and after consecutive flights to three intercontinental destinations. Results of multilevel analyses revealed that colleague support had unique positive effects on self-efficacy and work engagement. Self-efficacy did not mediate the relationship between support and engagement, but work engagement mediated the relationship between self-efficacy and (in-role and extra-role) performance. In addition, colleague support had an indirect effect on in-role performance through work engagement. These findings shed light on the motivational process as outlined in the JD-R model, and suggest that colleague support is an important job resource for flight attendants helping them reach their work-related goals.

  9. An alternative method to study star cluster disruption

    CERN Document Server

    Gieles, Mark

    2008-01-01

    Many embedded star clusters do not evolve into long-lived bound clusters. The most popular explanation for this "infant mortality" of young clusters is the expulsion of natal gas by stellar winds and supernovae, which leaves up to 90% of them unbound. A cluster disruption model has recently been proposed in which this mass- independent disruption of clusters proceeds for another Gyr after gas expulsion. In this scenario, the survival chances of massive clusters are much smaller than in the traditional mass-dependent disruption models. The most common way to study cluster disruption is to use the cluster age distribution, which, however, can be heavily affected by incompleteness. To avoid this, we introduce a new method, based on size-of-sample effects, namely the relation between the most massive cluster, M_max, and the age range sampled. Assuming that clusters are sampled from a power-law initial mass function, with index -2 and that the cluster formation rate is constant, M_max scales with the age range sam...

    Aim: Health professionals especially the dental professional are the frequent targets of musculoskeletal disorders (MSD). Complementary and alternative medicine (CAM) can be of some help in managing these MSD especially in. The purpose of this study was to determine the prevalence of CAM therapies as a treatment modality for MSD management among dental professionals of north India. Materials and Methods: Registered dentist of North Indian origin, India (n = 3598) were included in the study. The questionnaire was sent to all the dentists which consisted of the demographic profile, MSD in the past year, CAM therapies utilization and opinion about CAM therapies. Data analysis was done using SPSS version 21 and data were presented in tabular and graphic form. Test of significance was done using chi-square statistics with P < 0.05 considered as significant. Results: A response rate of 80% (n = 2879) was obtained, and all complained of MDS in some or the other part of their life. The use of CAM was reported among 70% (n = 2015) of the dentist who suffered from MSD. Other dentists either used conventional treatment or did not use anything. Conclusion: As the name implies, alternative medical systems is a category that extends beyond a single modality and refers to an entire system of theory and practice that developed separately from conventional medicine. CAM should be subject to rigorous scientific inquiry so that interventions that work are systematically distinguished from those that do not. In addition, the use of CAM treatments should be based on evidence of effectiveness and safety as demonstrated in randomized clinical trials. PMID:26692749

    Full Text Available The purpose of this paper is to explore the practice of alternative medicine as an experience capable of modifying the very perception of the body and body feeling, based in a two-field research in France (Paris and Brazil (Rio de Janeiro. In this research, the resort to alternative medicines was considered as urban practice and a possible response to emotional needs, beyond the curative specificities of these medicines. The two countries were chosen for their supposed complementarity concerning the perception of spirituality and therefore, the perception of holistic health concepts. The study relies on an inductive approach and a qualitative methodology: introspective interviews with consumers and professionals, as well as participant observations. After a review of the theoretical aspects on the subject — concepts related to health, alternative medicine, transformative experience —, empirical results are presented. They show that the experience of alternative medicine tends to modify body perception, understood as how individuals define their own body. It also tends to modify body internal feeling, literally how people feel their body. The second conclusion that can be drawn from our study is that, beyond cultural specificities, some similarities appear in the way the practice of alternative medicine impacts on body perception and individual values. In that sense, alternative medicine practices in big urban centers appear to be related to a global consumer culture. However, alternative health behaviors rely on a subjective quest of sense which can be expressed through a variety of practices related to better health, not necessarily involving consumption.

    Sixty nurses from five countries (Canada, India, Ireland, Japan, and Korea) took part in 11 focus groups that discussed the question: Do you consider your work meaningful? Fostering meaning and mentorship as part of the institutional culture was a central theme that emerged from the discussions. In this article, we begin with a background discussion of meaning and meaningful work as presented in the literature related to existentialism and hardiness. Next, we describe the method and analysis processes we used in our qualitative study asking how nurses find meaning in their very challenging work and report our findings of four themes that emerged from the comments shared by nurses, specifically relationships, compassionate caring, identity, and a mentoring culture. After offering a discussion of our findings and noting the limitations of this qualitative study, we conclude that nursing leaders and a culture of mentorship play an important role in fostering meaningful work and developing hardy employees.

  16. LCA to choose among alternative design solutions: The case study of a new Italian incineration line

    International Nuclear Information System (INIS)

    At international level LCA is being increasingly used to objectively evaluate the performances of different Municipal Solid Waste (MSW) management solutions. One of the more important waste management options concerns MSW incineration. LCA is usually applied to existing incineration plants. In this study LCA methodology was applied to a new Italian incineration line, to facilitate the prediction, during the design phase, of its potential environmental impacts in terms of damage to human health, ecosystem quality and consumption of resources. The aim of the study was to analyse three different design alternatives: an incineration system with dry flue gas cleaning (without- and with-energy recovery) and one with wet flue gas cleaning. The last two technological solutions both incorporating facilities for energy recovery were compared. From the results of the study, the system with energy recovery and dry flue gas cleaning revealed lower environmental impacts in relation to the ecosystem quality. As LCA results are greatly affected by uncertainties of different types, the second part of the work provides for an uncertainty analysis aimed at detecting the extent output data from life cycle analysis are influenced by uncertainty of input data, and employs both qualitative (pedigree matrix) and quantitative methods (Monte Carlo analysis).

    2013-08-01

    Full Text Available Ecovillages have grown in number around the world since the early 1990s. This growth appears to be largely due to the contested nature of post/modernity and the desire to establish a more simple, meaningful and sustainable lifestyle that is centered on community. The end of the 1990s represented the high tide of neo-liberalism in most advance liberal democracies. Ten years later, and the global economy still demonstrates signs that modes of capitalism have intensified and spread under the influence of global and state orchestrated markets, giving rise to a search for alternatives that might provide other mechanisms for organizing our lives. Cloughjordan Ecovillage is used to examine how governance through a consensus-based decision-making approach works as an alternative in this circumstance. Generally, intentional communities are organized around egalitarian principles and therefore commonly embrace the ideology of consensus. The primary research question guiding this study was—Does consensus work in the governance of alternative lifestyles? The preliminary findings of this case study suggests that in spite of the impressive nature of the built infrastructure at this site, the community continues to struggle with consensus-based decision-making as a form of self-organization and governance.

    The Systems Definition Branch deals with preliminary concepts/designs of various projects currently in progress at NASA. One of these projects is called the First Lunar Outpost. The First Lunar Outpost (FLO) is a proposed permanent lunar base to be located on the moon. In order to better understand the Lunar Habitat, a detailed analysis of the lunar environment as well as conceptual studies of the physical living arrangements for the support crew is necessary. The habitat will be inhabited for a period of 45 days followed by a six month dormant period. Requirements for the habitat include radiation protection, a safe haven for occasional solar flare storms, an airlock module and consumables to support a crew of 4 with a schedule of 34 extra vehicular activities. Consumables in order to sustain a crew of four for 45 days ranges from 430 kg of food to only 15 kg for personal hygiene items. These consumables must be brought to the moon with every mission. They are transported on logistics carriers. The logistics carrier must be pressurized in order to successfully transport the consumables. Refrigeration along with other types of thermal control and variation in pressure are defined by the list of necessary consumables. The objective of the proposed work was to collaborate the Habitat Team with their study on Logistic Carriers as possible alternatives for additional habitable volume. Options for possible reuses was also determined. From this analysis, a recommended design is proposed.

    2012-01-01

    Using a multilevel framework, this study examined the role of empowering leadership at the group level by fire brigade captains in facilitating the individual level motivational processes that underpin work engagement in volunteer firefighters. Anonymous mail surveys were completed by 540 volunteer firefighters from 68 fire brigades and, separately, by 68 brigade captains. As predicted on the basis of the Job Demands-Resources model, increased levels of cognitive demands and cognitive resources partially mediated the relationship between empowering leadership and work engagement. In a three-way Leadership × Demands × Resources interaction, empowering leadership also had the effect of optimizing working conditions for engagement by strengthening the positive effect of a work context in which both cognitive demands and cognitive resources were high. Our findings shed light on a process through which leaders can empower workers and enhance well-being: via their influence on and interaction with the work environment. They also underscore the need to examine work engagement from a multilevel theoretical perspective. PMID:22409390

    Full Text Available Abstract Background Adverse psychosocial work environments may lead to impaired mental health, but it is still a matter of conjecture if demonstrated associations are causal or biased. We aimed at verifying whether poor psychosocial working climate is related to increase of redeemed subscription of antidepressant medication. Methods Information on all antidepressant drugs (AD purchased at pharmacies from 1995 through 2006 was obtained for a cohort of 21,129 Danish public service workers that participated in work climate surveys carried out during the period 2002–2005. Individual self-reports of psychosocial factors at work including satisfaction with the work climate and dimensions of the job strain model were obtained by self-administered questionnaires (response rate 77,2%. Each employee was assigned the average score value for all employees at his/her managerial work unit [1094 units with an average of 18 employees (range 3–120]. The risk of first-time AD prescription during follow-up was examined according to level of satisfaction and psychosocial strain by Cox regression with adjustment for gender, age, marital status, occupational status and calendar year of the survey. Results The proportion of employees that received at least one prescription of ADs from 1995 through 2006 was 11.9% and prescriptions rose steadily from 1.50% in 1996 to the highest level 6.47% in 2006. ADs were prescribed more frequent among women, middle aged, employees with low occupational status and those living alone. None of the measured psychosocial work environment factors were consistently related to prescription of antidepressant drugs during the follow-up period. Conclusion The study does not indicate that a poor psychosocial work environment among public service employees is related to prescription of antidepressant pharmaceuticals. These findings need cautious interpretation because of lacking individual exposure assessments.

    Grit, defined as perseverance of effort and consistency of interest, has attracted attention as a predictor of success in various fields beyond IQ and the Big Five personality dimension of Conscientiousness. The purpose of the current study was to examine previously uninvestigated questions regarding grit using a cross-sectional design among a large number of working adults in Japan. First, we tested geographical generalizability of associations between grit and orientations towards happiness by comparing previous studies in the U.S. and the current study in Japan. It was confirmed that orientation towards meaning rather than orientation towards engagement had a stronger positive correlation with grit in our sample of Japanese people. This result is inconsistent with previous studies in the U.S. Furthermore, the Big Five dimension of Openness to Experience was newly confirmed as having a positive association with grit. Second, we examined the association between grit and work engagement, which is considered as an outcome indicator for work performance. In this analysis, grit was a strong predictor for work performance as well as academic performance. PMID:26335001

  20. Oxidising alternative species to chromium VI in zinc-galvanised steel surface treatment. Part 2. An electrochemical study

    International Nuclear Information System (INIS)

    In the first part of this work, the authors present the main results and conclusions of a morphological and chemical study carried out on zinc conversion layers (ZCLs) obtained with oxidising alternative passivation baths, that includes molybdates, permanganates, van[ates and tungstates. A good chromate-based bath was used as reference. In this second part of the work, the authors present the main results obtained on selected zinc conversion layers (ZCLs), using a.c. electrochemical impedance spectroscopy (EIS). The results obtained were correlated with the morphological and chemical data obtained with the same ZCLs in the first part of this work. Finally, it is concluded that the alternative ZCLs studied, does not seem to be as efficient as that obtained with a chromate-based passivation bath used as reference. It is believed that a better understanding of the mechanisms involved in the ZCL's formation, can be useful for studying, in the very near future, possible synergetic effects between molybdates and other chemical species.

  3. Working point and resonance studies at the CERN Proton Synchrotron

    CERN Document Server

    Huschauer, Alexander; Steerenberg, Rende

    The Proton Synchrotron (PS) is the oldest yet the most versatile particle accelerator operating at CERN. Having accelerated a multitude of different particle species within the last five decades, it is today used to define the longitudinal structure of the proton beams going into collision in the Large Hadron Collider (LHC), and thus constitutes an integral part of the LHC injector chain. Around 2020 the LHC will be subject to an upgrade to significantly increase the number of collisions at the interaction points. The beam parameters demanded by the High Luminosity LHC (HL-LHC) will, as a result, require substantial improvements of the pre-accelerators, which are currently being studied within the LHC Injectors Upgrade (LIU) project. The increase of luminosity will be accompanied by an increase of beam intensity, which might result in instabilities appearing on the injection flat bottom of the PS. Transverse Head-Tail instabilities have already been observed on operational LHC beams and an alternative stabili...

    Full Text Available Violence at work is a growing problem for organizations. It involves significant costs for the organization, its members and the community. In its various dimensions, organized violence is one of the least investigated. This study provides evidence of the relevance of this dimension has on the development of violent behavior in the workplace. The results indicate that practices an organization implements an impact on levels of violence that occur at work. For the development of healthy organizations, free of violence, the company management must take a holistic approach and look at best practices related to human resource management, with leadership factors or job design

    2004-06-01

    International students' medical training often includes an elective placement in their home country to prepare them for practice on graduation. Seven Malaysian students in their final year of medicine were interviewed pre- and post-graduation and asked to reflect on whether they felt adequately prepared for working in Malaysia. These seven international students, who studied medicine in Australia, all returned to Malaysia for six weeks for their elective, and the interviews canvassed their perceptions of this experience, along with their thoughts on how well their training in Australia had prepared them for working in their country of origin. The interview data were qualitatively analysed, and case studies were constructed. Main themes were identified and tabulated. Students voiced similar concerns about how ready they were for working at home. These included a lack of practical skills relative to their Malaysian-trained counterparts, language difficulties, medical communication skill incompatibilities across cultures, expectations to perform complex or unfamiliar tasks with minimal supervision and substantial burdens of responsibility with long working hours. These students did not feel greatly prepared for their return home to practise medicine. The elective placement was not well utilized by the majority of students in this study. PMID:15203848

  6. Full receiver operating characteristic curve estimation using two alternative forced choice studies.

    2016-01-01

    Task-based medical image quality is typically measured by the degree to which a human observer can perform a diagnostic task in a psychophysical human observer study. During a typical study, an observer is asked to provide a numerical score quantifying his confidence as to whether an image contains a diagnostic marker or not. Such scores are then used to measure the observers' diagnostic accuracy, summarized by the receiver operating characteristic (ROC) curve and the area under ROC curve. These types of human studies are difficult to arrange, costly, and time consuming. In addition, human observers involved in this type of study should be experts on the image genre to avoid inconsistent scoring through the lengthy study. In two-alternative forced choice (2AFC) studies, known to be faster, two images are compared simultaneously and a single indicator is given. Unfortunately, the 2AFC approach cannot lead to a full ROC curve or a set of image scores. The aim of this work is to propose a methodology in which multiple rounds of the 2AFC studies are used to re-estimate an image confidence score (a.k.a. rating, ranking) and generate the full ROC curve. In the proposed approach, we treat image confidence score as an unknown rating that needs to be estimated and 2AFC as a two-player match game. To achieve this, we use the ELO rating system, which is used for calculating the relative skill levels of players in competitor-versus-competitor games such as chess. The proposed methodology is not limited to ELO, and other rating methods such as TrueSkill™, Chessmetrics, or Glicko can be also used. The presented results, using simulated data, indicate that a full ROC curve can be recovered using several rounds of 2AFC studies and that the best pairing strategy starts with the first round of pairing abnormal versus normal images (as in the classical 2AFC approach) followed by a number of rounds using random pairing. In addition, the proposed method was tested in a pilot human

  7. Barriers to partnership working in public health: a qualitative study.

    Directory of Open Access Journals (Sweden)

    David Carlton Taylor-Robinson

    Full Text Available BACKGROUND: Public health provision in England is undergoing dramatic changes. Currently established partnerships are thus likely to be significantly disrupted by the radical reforms outlined in the Public Health White Paper. We therefore explored the process of partnership working in public health, in order to better understand the potential opportunities and threats associated with the proposed changes. METHODOLOGY/PRINCIPAL FINDINGS: 70 participants took part in an in-depth qualitative study involving 40 semi-structured interviews and three focus group discussions. Participants were senior and middle grade public health decision makers working in Primary Care Trusts, Local Authorities, Department of Health, academia, General Practice and Hospital Trusts and the third sector in England. Despite mature arrangements for partnership working in many areas, and much support for joint working in principle, many important barriers exist. These include cultural issues such as a lack of shared values and language, the inherent complexity of intersectoral collaboration for public health, and macro issues including political and resource constraints. There is particular uncertainty and anxiety about the future of joint working relating to the availability and distribution of scarce and diminishing financial resources. There is also the concern that existing effective collaborative networks may be completely disrupted as the proposed changes unfold. The extent to which the proposed reforms might mitigate or potentiate these issues remains unclear. However the threats currently remain more salient than opportunities. CONCLUSIONS: The current re-organisation of public health offers real opportunity to address some of the barriers to partnership working identified in this study. However, significant threats exist. These include the breakup of established networks, and the risk of cost cutting on effective public health interventions.

  8. Theoretical and experimental studies on combustion of alternative fuels in cement kilns

    International Nuclear Information System (INIS)

    In this thesis, the utilization of alternative fuels for NOx reduction by means of reburning and advanced reburning is considered. Laboratory experiments, full-scale experiments and computational fluid dynamic (CFD) simulations are the basis of the thesis. The goal of the work was to characterize alternative fuels used in cement kilns, with focus on the processes taking place in the precalciner of the cement kiln. To facilitate testing under controlled process conditions, a lab-scale circulating fluidized bed combustion (CFBC) reactor was designed and constructed. A co prehensive study on the fluidization regime in CFBC reactors and precalciners was required to ensure and verify that the operational regime in the CFBC reactor was similar to the regime in a precalciner. Different alternative fuels, such as refuse derived fuel, animal meal and solid hazardous waste, were tested in the CFBC reactor, which proved well suited for characterization of alternative fuels and investigations of NOx reduction, even though the operation of a CFBC reactor is quite complex and gives a certain variation in stability. Experiments with and without circulating mass in the CFBC reactor demonstrated the importance of executing the laboratory combustion experiments in an environment similar to that in the full-scale process, i.e. in the precalciner. Animal meal is believed to follow the reduction route of selective non-catalytic r duction or advanced reburning and to have a special capability of reducing NOx during increased NOx concentrations at the reactor inlet. The increased CO emissions during advanced reburning and reburning with animal meal are most likely to be due to the competition for the OH radical during oxidation of CO and of NH3. Furthermore, it was shown, for all fuels, that an increased concentration of NOx at the reactor inlet increases the ratio of NOx at the exit and NOx supplied. Full-scale experiments were executed at Norcem's kiln 6 in Brevik, using solid

    2007-01-01

    The National Park Service (NPS) is increasingly focusing on alternative transportation systems in national parks to address environmental and social problems arising from a historical reliance on personal automobiles as the primary means of visitor access. Despite the potential advantages, alternative transportation may require a reorientation in the way that Americans have experienced national parks since the advent of auto-tourism in the early twentieth century. Little research exists, however, on visitor perspectives towards alternative transportation or the rationale underlying their perspectives. It remains unclear how transportation systems affect visitors’ experiences of the park landscape or the factors influencing their travel behavior in the parks. This report presents an interpretive study of visitor perspectives toward transportation management in the Yosemite Valley area of Yosemite National Park, California. Qualitative analysis of 160 semi-structured interviews identified individual psychological factors as well as situational influences that affect visitors’ behavior and perspectives. Individual psychological factors include perceived freedom, environmental values and beliefs, prior experience with Yosemite National Park and other national parks, prior experience with alternative transportation in national parks, and sensitivity to subjective perceptions of crowding. Situational factors included convenience, access, and flexibility of travel modes, as well as type of visit, type of group, and park use level. Interpretive communication designed to encourage voluntary visitor use of alternative transportation should focus on these psychological and situational factors. Although challenges remain, the results of this study suggest approaches for shaping the way Americans visit and experience their national parks to encourage environmental sustainability.

    Full Text Available The aim of this review was to evaluate research relating to the effects of coping strategies and resilience on the level of workplace stress. Much of the research focused on working mothers and working females in general. It was found that working females experienced more work stress as compared to men. And currently in Malaysia, social policies that support working females, especially working mothers, has not been adopted fully by most corporations. Furthermore, the evidence for effective problem-focused and emotion-focused coping was inconsistent. It was concluded that correlation between work stressors and the adopted coping strategies may vary depending on the type of problems being dealt with and the interplay between the employee and the demand. Moreover, resilience literature revealed this concept as an enhancement of an individual’s adaptability and survival in the presence of occupational stressors and success in overcoming the stressors results in increased resilience to future hardships. This article identifies a number of research gaps for advancing work stress research, in particular: 1 limited work stress research on Malaysian working women and mothers, and; 2 limited literature on relating resilience to coping strategies and work stress.

  17. Alternatives study for the treatment of solid radioactive waste arising from depleted Uranium pellets

    International Nuclear Information System (INIS)

    Technical feasibility for the treatment of solid waste composed by pellets containing depleted U is studied. The objective is to count with an available alternative to assure the complying of the in force Nuclear Safety Law (Ley 18.302) for the management of this waste. After waste characterization, different lixiviation agents were probed at laboratory. In parallel, the direct immobilization using a cementitious matrix was developed. Lixiviation was experimented in three steps. First, dilute sulphuric acid is added to the solid waste, then a NaClO3 solution is added for the U oxidation. Finally, the waste is submitted to curing by lixiviation in concentrated sulphuric acid. A series of several cementitious mixture were employed to prepare samples for physical resistance test, which helped to determine the work zone in a ternary diagram for the high resistance samples fabrication using these mixtures. Oxidant lixiviation plus acid curing steps give a 40% extraction of U, with which the decreasing in U concentration is equivalent to a non radioactive material, according to national regulation, though an economic analysis (cost-benefit) is required for this last, as well. By the other side, the mixture composition of the waste for direct immobilization offers a good conditions workable matrix. Setting time is about 12 hours, without the use of process accelerants. The solid waste form obtained presents a compression resistance of 172 [Kgf/cm2] at 28 days aged. Composition is 61.10% waste, 20.37% cement and 18.53% waste. As conclusion from this experimental study, it is observed that the solid waste may be treated by lixiviation, or, immobilized in a cement matrix with a cost for this last of 0.066 [UF/Kg] equivalent to 1.75 [US$/ Kg] (AS)

  5. Final cost reduction study for the Geysers Recharge Alternative. Volume 1

    Energy Technology Data Exchange (ETDEWEB)

    1997-11-01

    The purpose of this study is to determine whether or not cost reduction opportunities exist for the Geysers Recharge Alternative as defined in the Santa Rosa Subregional Long-Term Wastewater Project EIR/EIS. The City of Santa Rosa has been directed to have a plan for reclaimed water disposal in place by 1999 which will meet future capacity needs under all weather conditions. A Draft EIR/EIS released in July 1996 and a Final EIR certified in June 1997 examine four primary alternatives plus the No Action Alternative. Two of the primary alternatives involve agricultural irrigation with reclaimed water, either in western or southern Sonoma County. Another involves increased discharge of reclaimed water into the Russian River. The fourth involves using reclaimed water to replenish the geothermal reservoir at the Geysers. The addition of this water source would enable the Geysers operators to produce more steam from the geothermal area and thereby prolong the life and economic production level of the steamfield and the geothermal power plants supplied by the steamfield. This study provides additional refined cost estimates for new scenarios which utilize an alternative pipeline alignment and a range of reclaimed water flows, which deliver less water to the Geysers than proposed in the EIR/EIS (by distributing flow to other project components). Also, electrical power rates were revised to reflect the recent changes in costs associated with deregulation of the power industry. In addition, this report provides information on sources of potential public and private funding available and future environmental documentation required if the cost reduction scenarios were to be selected by the City as part of their preferred alternative.

    The authors conducted a work-related stress surveillance study in 2013 on 6,558 public-sector employees in Italy, examining how they perceived their jobs, via the Job Content Questionnaire, and their mental health status, via the General Health Questionnaire 12 (GHQ-12). Of the 2,094 employees completing the questionnaires, 60% were male, 52% had a medium-level education, and 76% had a medium-level job. Three hundred and eighty-five employees (18%) had a GHQ-12 score >3 and were classified as GHQ-12 cases: these were more often female (54%), medium-to-highly educated (54%), and had more often reported health problems over the previous year (51%). Thus, GHQ-12 cases represented a significant percentage of the examined population, indicating that work-related stress surveillance programs are needed for the planning of psychosocial interventions aimed at the reintegration of individuals with mental health problems.

  16. The Transitive-Unaccusative Alternation: A Cross-Modal Priming Study.

    Fadlon, Julie

    2016-06-01

    The relationship between different linguistic manifestations of an eventuality-denoting concept, referred to in the literature as diatheses or voices, is well-studied in theoretical linguistics. Among researchers studying this phenomenon, it is widely agreed that there is a systematic relationship between the various diatheses of a concept. However, when a specific alternation is addressed, the nature of this relationship, namely, its directionality, is at debate. This research employs the much-debated transitive-unaccusative alternation as a case-study and reports the results of two cross-modal priming experiments designed to explore how Hebrew speakers perceive it. The results reveal an asymmetry between the facilitating effects of transitives and unaccusatives, thus suggesting that the relationship between these diatheses is directional. As a whole, this study demonstrates that theoretical debates regarding derivational relationships can be addressed by means of psycholinguistic research. PMID:25929875

  18. Report on the Savannah River Site aluminum-based spent nuclear fuel alternatives cost study

    International Nuclear Information System (INIS)

    Initial estimates of costs for the interim management and disposal of aluminum-based spent nuclear fuel (SNF) were developed during preparation of the Environmental Impact Statement (EIS) on the Nuclear Weapons Nonproliferation Policy Concerning Foreign Research Reactor Spent Nuclear Fuel. The Task Team evaluated multiple alternatives, assessing programmatic, technical, and schedule risks, and generated life-cycle cost projections for each alternative. The eight technology alternatives evaluated were: direct co-disposal; melt and dilute; reprocessing; press and dilute; glass material oxidation dissolution system (GMODS); electrometallurgical treatment; dissolve and vitrify; and plasma arc. In followup to the Business Plan that was developed to look at SNF dry storage, WSRC prepared an addendum to the cost study. This addendum estimated the costs for the modification and use of an existing (105L) reactor facility versus a greenfield approach for new facilities (for the Direct Co-Disposal and Melt and Dilute alternatives). WSRC assessed the impacts of a delay in reprocessing due to the potential reservation of H-Canyon for other missions (i.e., down blending HEU for commercial use or the conversion of plutonium to either MOX fuel or an immobilized repository disposal form). This report presents the relevant results from these WSRC cost studies, consistent with the most recent project policy, technology implementation, canyon utilization, and inventory assumptions. As this is a summary report, detailed information on the technical alternatives or the cost assumptions raised in each of the above-mentioned cost studies is not provided. A comparison table that briefly describes the bases used for the WSRC analyses is included as Appendix A

  20. Semiotic Analysis in the Study of Social Work

    Laine, Terhi

    2009-12-01

    Full Text Available Research and professional practices have the joint aim of re-structuring the preconceived notions of reality. They both want to gain the understanding about social reality. Social workers use their professional competence in order to grasp the reality of their clients, while researchers’ pursuit is to open the secrecies of the research material. Development and research are now so intertwined and inherent in almost all professional practices that making distinctions between practising, developing and researching has become difficult and in many aspects irrelevant. Moving towards research-based practices is possible and it is easily applied within the framework of the qualitative research approach (Dominelli 2005, 235; Humphries 2005, 280. Social work can be understood as acts and speech acts crisscrossing between social workers and clients. When trying to catch the verbal and non-verbal hints of each others’ behaviour, the actors have to do a lot of interpretations in a more or less uncertain mental landscape. Our point of departure is the idea that the study of social work practices requires tools which effectively reveal the internal complexity of social work (see, for example, Adams & Dominelli & Payne 2005, 294 – 295. The boom of qualitative research methodologies in recent decades is associated with much profound the rupture in humanities, which is called the linguistic turn (Rorty 1967. The idea that language is not transparently mediating our perceptions and thoughts about reality, but on the contrary it constitutes it was new and even confusing to many social scientists. Nowadays we have got used to read research reports which have applied different branches of discursive analyses or narratologic or semiotic approaches. Although differences are sophisticated between those orientations they share the idea of the predominance of language. Despite the lively research work of today’s social work and the research-minded atmosphere of

  1. Practising Knowing at Work: a case study in healthcare

    Directory of Open Access Journals (Sweden)

    Manidis, Marie

    2015-12-01

    Full Text Available In healthcare today, medical knowledge is still largely viewed by the health sector as an ‘epistemology of possession’; a perspective which gives primacy to knowledge transfer and communication aspects of care. In my view, this perspective underestimates the complexity of the social, material, situated and collective way that doctors and nurses actually work together – and do knowledge – in order to care for their patients . I illustrate this complexity based on data from a large Australian Research Council (ARC study by closely examining a case study of how a healthcare team cares for a dying 67-year old patient, Joel in an Emergency Room (ER. Drawing on ethnographic and linguistic ethnographic methodologies and data, ‘knowledge’ is proposed, not as ‘possession’, but as an activity, ‘a collective and distributed ‘doing’ situated in time and space, and therefore taking place in [the] work practices [of the ERs nurses and doctors]. Theoretically the paper adopts a ‘practice-based’ analysis of how team knowledge is done in the ER. In adopting this approach the paper challenges conventional views on knowledge, knowledge transfer and communication in healthcare – and more broadly in other organizational contexts – alerting us to new ways of thinking about how team knowledge is done and how organizational learning might be reconceptualized.

    Full Text Available Unemployment is believed as one of most important issues in today's economy around the world. The recent economic turmoil in European countries, for instance, has created some troubles such as increase in rate of depression, divorce, etc. In this paper, we present a social study work in one of regions of Iran. The proposed study of this paper designs and distributes a questionnaire among 80 experts who live in the region and tries to understand whether there is a correlation between unemployment and rubbery, immigration, drug addiction and non-value jobs. The survey uses Pearson correlation to test four hypotheses and the results indicate that although there is no strong correlation between unemployment and rubbery and immigration but there is a strong evidence to believe that unemployment can increase drug addiction and non-value added jobs.

    This paper presents the results of a preliminary structural sizing and alternate material trade study for NASA s Crew Exploration Vehicle (CEV) Crew Module (CM). This critical CEV component will house the astronauts during ascent, docking with the International Space Station, reentry, and landing. The alternate material design study considers three materials beyond the standard metallic (aluminum alloy) design that resulted from an earlier NASA Smart Buyer Team analysis. These materials are graphite/epoxy composite laminates, discontinuously reinforced SiC/Al (DRA) composites, and a novel integrated panel material/concept known as WebCore. Using the HyperSizer (Collier Research and Development Corporation) structural sizing software and NASTRAN finite element analysis code, a comparison is made among these materials for the three composite CM concepts considered by the 2006 NASA Engineering and Safety Center Composite Crew Module project.

    Full Text Available Drawing on information from the Encuesta de la Transición de la Escuela al Trabajo 2012 (Survey on the Transition from School to Work, this study analyzes the characteristics of young people who are not in education, employment or training (NEETs. We find that, overall, 17.94% of Peruvian urban youth between 15 and 29 years of age are NEETs. Of these, around three quar- ters (74.09% are females, which points toward the presence of factors associated with gender, such as fertility, the role within the household economy, or educational reasons, such as the explanatory variables in the previous result.Accordingly, the likelihood of being a NEET increases for females if there are children in the house- hold and if the individual has a partner, while the reverse is true in the case of males. Moreover, the likelihood of belonging to the NEET group increases when there are young men in the household; decreases when they are heads of household; if there is production in the household; or if the part- ner is engaged in domestic work. As regards individual decisions, young people’s life goals affect the likelihood of being a NEET. Moreover, the higher the level of education, the lower the likelihood of being a NEET due to the greater opportunity cost associated with better earning prospects.

    The purpose of the present report was the study and identification of an unspecified sample on a work of art by means only of a microscope coupled to a Raman spectrometer. The origin of the fragment was unknown. The Raman spectra on the virgin sample were giving no results because of a deteriorated surface treatment, in spite of the evident blue color identified by microscopic visual inspection. The sample fragmentation and the preparation of a KBr pellet allowed the distribution of the painting layers of the different components on a flat substrate reducing surface effects. Selecting the areas of different color and focusing there it was possible to identify the pigments from their Raman spectra locally acquired by selective excitation. Raman spectra were assigned by comparison with published databases. It was possible to connect Carbon Black and Orange iron oxide, as documented historically, as constituents of Azurite preparatory layer Morellone, according to a technique generally employed to allow the use ...

  14. Enhancing Fluoride: Clinical Human Studies of Alternatives or Boosters for Caries Management.

    Science.gov (United States)

    Fontana, Margherita

    2016-01-01

    Dental caries remains a major public health problem, especially for certain high-risk population groups. The goal of this study was to assess the evidence regarding strategies meant to be used as alternatives or booster/supplements to fluoride for caries prevention and management. Articles were selected for inclusion if they had a prospective longitudinal design, with a fluoride control arm, and were conducted in human subjects. Of the included studies, 7/18 studies on calcium-based strategies favored the test product (the majority of studies included exposure of fluoride in all groups). All the arginine studies (8/8) included a combination of arginine and a calcium base, and concluded that this has the potential to significantly boost the performance of fluoride. The remaining included studies focused on the addition of microbial-related strategies to a fluoride-containing vehicle (2 xylitol studies and 1 study using a probiotic milk), and all favored the combination as a booster to fluoride. Thus, the current study did not identify evidence for any strategy to effectively be used as a substitute or alternative to fluoride, but identified some consistent evidence derived from the use of prebiotic strategies (primarily from use of arginine combined with calcium) to support their potential use to boost the mechanism of action of fluoride. Thus, fluoride-based strategies remain the standard for caries prevention and management, with some evidence that boosting the effects of fluoride by the use of prebiotic strategies is a promising possibility.

Students were participants in the Team COOL (Controlling Overweight and Obesity for Life pilot study, a group randomized obesity prevention pilot trial. Mixed model multivariate analyses procedures were used to assess associations of interest. Results Daily cigarette smoking was reported by 36% of students. Cigarette smoking was positively associated with consumption of regular soda (p = 0.019, high-fat foods (p = 0.037, and fast food restaurant use (p = 0.002. Alcohol (p = 0.005 and marijuana use (p = 0.035 were positively associated with high-fat food intake. With increasing numbers of substances, a positive trend was observed in high-fat food intake (p = 0.0003. There were no significant associations between substance use and fruit and vegetable intake. Conclusions Alternative high school students who use individual substances as well as multiple substances may be at high risk of unhealthful dietary practices. Comprehensive health interventions in alternative high schools have the potential of reducing health-compromising behaviors that are prevalent among this group of students. This study adds to the limited research examining substance use and diet among at-risk youth. Trial registration number ClinicalTrials.gov: NCT01315743

  17. Value engineering study report on Lower East Fork Poplar Creek Project. Alternative No. 3

    International Nuclear Information System (INIS)

    The project under study is Alternative No. 3 as identified in the Feasibility Study dated August 1994. This alternative is identified as Excavation and Disposal of Commercial/DOE, Other, and Residential Remedial Unit Soil. The assumptions used for generating baseline costs are discussed in site associated costs. It is further described as follows: Soils with mercury concentrations greater than 200 ppM in the Commercial/DOE and Other Remedial Units and greater than 180 ppM in the Residential Remedial Unit [41,300m3 (54,000yd3 a volume equivalent to approximately 6,750 dump truck loads)] would be excavated and disposed of in an approved, lined landfill at Y-12 with leachate collection and possible pretreatment of the leachate before discharge. Because 0.6 ha (1.5 acres) of wetland would be destroyed, wetlands banking would occur, whereby a 1.8-ha (4.5-acre) wetland would be constructed on DOE-owned land near K-25. Borrow soil would be obtained from the Y-12 West End Borrow Area or from excess soil located at Y-12 landfills to fill the excavation. It is estimated that 7.3 ha (18.2 acres, and area about the size of 17 football fields) of habitat would be adversely affected. This alternative would use BMPs to minimize any adverse affects and to comply substantively with regulatory requirements

  18. Study on development in professional work of radiological technologists

    International Nuclear Information System (INIS)

    This study explored several agenda related to license system, education, professional work of radiological technologists (RTs) and a transition process of law for them to investigate a developmental strategy of RTs as a professional career. The results are as followings: 1. The national license system for RTs was started from 1965, 1965-1972 x-ray technicians (medical assistance), 1973-present (2006) radiotechnologist (medical technologist) since then. 2. The average pass ratio of national license examination (1965-2006) for RTs was 46.6%. The method, subjects and level of the examination should be improved. 3. The education term for RTs has been changed since 1963; 1963-1990 two year college. 1991-1999 three year college, 2000-2006 four year and three year college depending on universities and colleges. As of 2006, there are twelve 4-year universities and eighteen 3-year colleges. The total number of new students were 1,965. 4. The new developmental paradigm should be made for technology education of RTs corresponding to the development of medicine and science. 5. The qualification system of clinical specialists in radio-technology field needs to be operated not by the non-governmental body (The-Korean Radiological Technologists Association) but by the governmental body. 6. The vertical relationship among RTs, doctors and other medical workers should be rebuilt through the revision of law. Especially, doctors and dentists 'guidance authority' for RTs should be changed to 'request authority'. 7. The service extent of RTs should be extended in medical fields corresponding to professional work of RTs and a revision of the law needed for this situation

  19. Tritium Related Studies Within the JET Fusion Technology Work Programme

    International Nuclear Information System (INIS)

    The JET Fusion Technology (FT) work programme was launched in 2000, in the frame of the European Fusion Development Agreement, to address issues related to JET and ITER. In particular, there are four topics related to tritium being investigated. Based on the experience gained on the existing tokamaks, first calculations indicate that in-vessel tritium retention could represent a burden for ITER operation. Therefore erosion/deposition studies are being performed in order to better understand the layer co-deposition and tritium retention processes in tokamaks. Moreover, testing of in-situ detritiation processes, in particular laser and flash lamp treatments, should assess detritiation techniques for in-vessel components in the ITER-relevant JET configuration.To reduce the constraints on waste disposal, dedicated procedures are being developed for detritiation of metals, graphite, carbon-fibre composites, process and housekeeping waste. During the operational and decommissioning phases of a fusion reactor, many processes will produce tritiated water. Key components for an ITER relevant water detritiation facility are being studied experimentally with the aim of producing a complete design that could be implemented and tested at JET. This paper describes these topics of the FT-programme, the strategy developed and the results obtained so far

  1. The Effects of Work Values and Work Centrality on Job Satisfaction. A study with older spanish workers

    Directory of Open Access Journals (Sweden)

    Alejandro Orgambídez-Ramos

    2013-09-01

    Full Text Available Since workforces are ageing throughout Europe, interest in the role of age in the workplace is increasing. Older workers with high work centrality are more likely to negotiate a relational contract and express higher levels of job satisfaction than older workers with low work centrality (Armstrong-Stassen and Schlosser, 2008. This study examines the role of work centrality and valued work outcomes as antecedents of job satisfaction. A cross sectional study using questionnaires was conducted. The sample consisted of 203 Spanish employees (M age = 55.78, SD = 3.01. Hierarchical multiple regression analyses have revealed that job satisfaction was significantly predicted by needed income and work centrality. When work is not an important part of older workers’ lives, they will prefer extrinsic outcomes and will not invest in the relationship with their organization (Grant & Wade-Benzoni, 2009. Implications for research and theory are explored in the conclusion.

    1994-01-01

    A collaborative study was conducted on an alternative sieving method for the extraction of light filth from cheeses. The alternative method was developed that is applicable to broad variety of cheeses. A 225 g test portion is dispersed in a solution of 5.7% HCl, Igepal CO-730, and Igepal DM-710. Digested cheese is wet-sieved on a No. 230 sieve. The residue is treated with Tergitol Anionic 4, transferred to 1% sodium lauryl sulfate solution, heated, and maintained at 65 degrees-75 degrees C for 10 min. The residue is washed with these 2 surfactants a maximum of 4 times until it is reduced to an amount that is filterable. The residue is filtered and the filter papers are examined microscopically at a magnification of ca 30x. Average recoveries by 9 collaborators for 3 spike levels of rat hairs (5, 10, and 15) were 80, 68, and 81%, respectively; for insect fragments (5, 15, and 30) recoveries were 97, 90, and 92%, respectively. The alternative sieving method for extraction of light filth from cheeses has been adopted first action by AOAC INTERNATIONAL. PMID:7950417

    This study consists of work done in support of the U.S. delegation to the NATO SAS-023 Antipersonnel Landmine Study Group, supplemented by additional work done for the U.S. Office of the Secretary of Defense Antipersonnel Landmine Alternative Concept Exploration Program (Track III). It explores the battlefield utility of current antipersonnel landmines (APL) in both pure and mixed APL/antitank minefields and evaluates the value of military suggested non-materiel alternatives. The historical record is full of examples where the presence (or absence) of antipersonnel landmines made a critical difference in battle. The current generation of military thinkers and writers lack any significant combat experience employing either mixed or antipersonnel minefields, which leaves a critical gap in available expert advice for policy and decision-makers. Because of this lack of experienced-based professional military knowledge, Lawrence Livermore National Laboratory analyzed the employment of antipersonnel landmines in tactical mixed minefields and in protective antipersonnel minefields. The scientific method was employed where hypotheses were generated from the tactics and doctrine of the antipersonnel landmine era and tested in a simulation laboratory. A high-resolution, U.S. Joint Forces Command combat simulation model (the Joint Conflict and Tactical Simulation--JCATS) was used as the laboratory instrument. A realistic European scenario was obtained from a multi-national USAREUR exercise and was approved by the SAS-023 panel members. Additional scenarios were provided by U.S. CINC conferences and were based on Southwest Asia and Northeast Asia. Weapons data was obtained from the U.S. family of Joint Munitions Effectiveness Manuals. The U.S. Army Materiel Systems Analysis Agency conducted a limited verification and validation assessment of JCATS for purposes of this study.

    The selectivity of a hot cavity resonance ionization laser ion source (RILIS) is most often limited by contributions from competing surface ionization on the hot walls of the ionization cavity. In this article we present investigations on the properties of designated high-temperature, low-work function materials regarding their performance and suitability as cavity material for RILIS. Tungsten test cavities, impregnated with a mixture of barium oxide and strontium oxide (BaOSrO on W), or alternatively gadolinium hexaboride (GdB6) were studied in comparison to a standard tungsten RILIS cavity as being routinely used for hot cavity laser ionization at ISOLDE. Measurement campaigns took place at the off-line mass separators at ISOLDE / CERN, Geneva and RISIKO / University of Mainz.

  9. Cross Functional Working and Concurrent Engineering – a UK Study

    Directory of Open Access Journals (Sweden)

    H. Williams

    2000-01-01

    Full Text Available This paper reports on the preliminary results of an investigative study into the implementation of concurrent engineering applied to new product development. Concurrent (or Simultaneous engineering is the term commonly given to creating new products using multi-disciplined teams of marketing, design, manufacturing and support functions together with supplier and customers. Such techniques have produced robust, low cost quality products in short concept to market times compared to traditional ones. The research investigated design management practice and performance in a number of organisations across a range of industrial sectors in the UK by means of a questionnaire survey. The results identify the current use of a variety of design practices and methodologies such as different organisational structures, the extent of cross-functional working, the use of design and phase reviews and the use of different technologies. They indicate that companies implementing CE are more successful in time to market performance than those who don’t implement CE. Factors most influencing the successful adoption of CE are design and phase reviews, and, to a lesser extent, the use of multifunctional teams and supplier partnerships.

    2013-01-01

    Case Studies in Control presents a framework to facilitate the use of advanced control concepts in real systems based on two decades of research and over 150 successful applications for industrial end-users from various backgrounds. In successive parts the text approaches the problem of putting the theory to work from both ends, theoretical and practical. The first part begins with a stress on solid control theory and the shaping of that theory to solve particular instances of practical problems. It emphasizes the need to establish by experiment whether a model-derived solution will perform properly in reality. The second part focuses on real industrial applications based on the needs and requirements of end-users. Here, the engineering approach is dominant but with theoretical input of varying degree depending on the particular process involved. Following the illustrations of the progress that can be made from either extreme of the well-known theory–practice divide, the text proceeds to a third part relate...

    2016-07-01

    The internal carotid artery (ICA) has been proposed as an alternative site to the middle cerebral artery (MCA) to measure dynamic cerebral autoregulation (dCA) using transcranial Doppler ultrasound (TCD). Our aim was to test the inter-operator reproducibility of dCA assessment in the ICA and the effect of interaction amongst different variables (artery source × operator × intra-subject variability). Two operators measured blood flow velocity using TCD at the ICA and MCA simultaneously on each side in 12 healthy volunteers. The autoregulation index (ARI) was estimated by transfer function analysis. A two-way repeated measurements ANOVA with post-hoc Tukey tested the difference between ARI by different operators and interaction effects were analysed based on the generalized linear model. In this healthy population, no significant differences between operator and no interaction effects were identified amongst the different variables. This study reinforced the validity of using the ICA as an alternative site for the assessment of dCA. Further work is needed to confirm and extend our findings, particularly to disease populations.

    International Nuclear Information System (INIS)

    Indium DTPA is the current radiopharmaceutical of choice for the evaluation of colonic transit in constipated patients. Its drawback encouraged the authors to look for an alternative tracer. It was found that gallium-67 citrate is versatile starting material for the preparation of many gallium complexes. Because of its lack of absorption from the gastro-intestinal tract, it has the following advantages over indium DTPA as a radioactive colonic transit marker: it is readily available, and being less than $1/MBq compared to $40/MBq, savings of up to $700 can be achieved per patient study. 5 refs., 2 tabs., 7 figs

    An overview of the organization and methodology of the Cogeneration Technology Alternatives Study is presented. The objectives of the study were to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the future and to assess the advantages of advanced technology systems compared to those systems commercially available today. Advanced systems studied include steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics. Steam turbines, open cycle gas turbines, combined cycles, and diesel engines were also analyzed in versions typical of today's commercially available technology to provide a base against which to measure the advanced systems. Cogeneration applications in the major energy consuming manufacturing industries were considered. Results of the study in terms of plant level energy savings, annual energy cost savings and economic attractiveness are presented for the various energy conversion systems considered.

    Hellstén, P; Nystén, T

    2003-01-01

    The migration of organic de-icers in the shallow aquifers typical in Finland is not well known and we need to find solutions to minimise the negative impacts of de-icing on groundwater quality. The objective of the MIDAS project is to find de-icers which have the least harmful impacts on groundwater quality. Migration of sodium chloride as a tracer and five alternative de-icers in aquifers was studied. The alternative de-icers were calcium chloride, magnesium chloride, calcium-magnesium-acetate, potassium acetate and potassium formate. The research consists of leaching of heavy metals from roadsides in the area of Highway 1 in southern Finland; an in vitro study, which represented the full length of winter at low temperatures; and the subsequent on-going field research in south-eastern Finland. So far, in our studies potassium formate caused fewer changes to the quality of the infiltrated water than the chlorides and acetates. After finishing the on-going research the results will be used to choose a preferred de-icer from the existing chemicals and for the development of new less harmful de-icers. The information will be used mainly in Scandinavia and North America where the hydrogeological conditions are similar to those in Finland. PMID:14703138

  5. A feasibility study of work group monitoring for Hanford

    International Nuclear Information System (INIS)

    Present Hanford internal dosimetry policy recommends placing a worker on a routine bioassay monitoring program if the 50-year committed effective dose equivalent (CEDE) in a single calendar year may exceed 100 mrem for all radionuclides. Nearly all Hanford workers who enter contamination zones are on routine bioassay programs. Site environmental restoration and remediation now require an even larger number of workers to enter contamination zones, therefore increasing the number of workers requiring routine bioassay monitoring. Work group bioassay is a method which demonstrates, at a reduced cost, that workers who are assumed to be essentially at no risk for incurring intakes are, in fact, not incurring intakes. For the proposed program, a work group will be identified by a letter to their exposure history file. The analytical result for a work group bioassay sample will be placed in the dosimetry record of the person actually providing the sample and will be identified as pertaining to a work group by an appropriate code. Any positive result will be followed up using the same procedure as for individual-specific bioassay, which limits false positives to less than 0.5%. Workers who (1) have radioactive material depositions that interfere with detecting and assessing additional intakes, (2) use any form of respiratory protection, or (3) enter airborne radioactivity areas will be excluded from a work group bioassay program and placed on an individual-specific bioassay program

    The specific problems associated with the work on board within the merchant fleet are well known and have over the years been a topic of discussion. The work conditions in the engine room (ER) are demanding due to, e.g. the thermal climate, noise and awkward working postures. The work in the engine control room (ECR) has over recent years undergone major changes, mainly due to the introduction of computers on board. In order to capture the impact these changes had implied, and also to investigate how the work situation has developed, a total of 20 engine officers and engine ratings were interviewed. The interviews were semi-structured and Grounded Theory was used for the data analysis. The aim of the present study was to describe how the engine crew perceive their work situation and working environment on board. Further, the aim was to identify areas for improvements which the engine crew consider especially important for a safe and effective work environment. The result of the study shows that the design of the ECR and ER is crucial for how different tasks are performed. Design which does not support operational procedures and how tasks are performed risk inducing inappropriate behaviour as the crew members' are compelled to find alternative ways to perform their tasks in order to get the job done. These types of behaviour can induce an increased risk of exposure to hazardous substances and the engine crew members becoming injured. PMID:20870214

  14. Numerical Study on Plume Interaction Above An Alternating Diffuser in Stagnant Water

    2006-01-01

    The plume interaction above an alternating diffuser in stagnant water is studied with 3D Reynolds-averaged Navier-Stokes equations (RANS) combined with a buoyancy-extended k-ε model. The steady three-dimensional turbulent flow and temperature fields are computed by use of the finite volume method on a non-uniform high resolution orthogonal grid. The numerical predictions demonstrate a generic flow pattern for different turbulent heated jet discharges: the buoyant jets on each side of the diffuser first merge to form an essentially two-dimensional plume which bends back toward the diffuser centerline due to a low pressure cavity. In general, an under-pressure exists in the cavity until the plumes merge; the pressure increases to slightly positive afterwards. Two-dimensionality of the scalar and flow field is attained much later than the point of zero pressure. The position of merging point is governed by mainly four parameters - the discharge densimetric Froude number, the port diameter and space, and the horizontal distance between alternating jet nozzles. A formula from numerical simulations is obtained through regression analysis and it is used to predict the position of plume merging point. The predicted temperature fields are comparable to previous experiments.

Workaholism was defined as the individual’s steady and considerable allocation of time to work, which is not derived from external necessities (1. The research studies about workaholics and workaholism have been increasing a lot in the last years (2. Workaholism is an addiction that actually is affecting a lot of people around the world and has serious consequences in personal life, in the community and also in economy. Some of these researches are directed to explore ways to diagnose when a person is workaholic and when this situation may affect the performance of the individual in work, daily life activities and especially in psychosocial area. Objective: this pilot study contributes to identify if Colombian workers present the main characteristics of workaholism and if the job they perform is related to the presence of the characteristics of this addiction. Materials and method: for this pilot study used the Dutch Work Addiction Scale (DUWAS, this test suggests when a person has work addiction, trough the evaluation of two main components working excessively and working compulsively. Results: the study find differences for the two groups: the 67% of the AE group are over the average while only the 33% of the members of the O group are over it. Conclusions: these percentages show that the combinations of the components of workaholism are more evident in the population belonging to the administrative/executive jobs group, giving evidence that workaholism is presented in greater proportion in the population performance management positions.

  17. Project Alternative Systems Study - PASS. Analysis of performance and long-term safety of repository concepts

    International Nuclear Information System (INIS)

    This study is part of the Project on Alternative Systems Study, PASS, with the overall aim to perform a technical/economical ranking of alternative repository concepts and canisters for the final storage of spent nuclear fuel. The comparison should in the first stage separately assess technology in construction and operation, long-term performance and safety, and costs. Three of the repository concepts are assumed to be located at a depth of approximately 500 m in the host rock, KBS-3, Very Long Holes (VLH) and Medium Long Holes (MLH). In the KBS-3 concept the canisters are deposited in vertical deposition holes in a system of parallel storage tunnels. In the VLH concept larger canisters are deposited in long horizontal tunnels. The MLH concept, is an evolution of the two other concepts, with KBS-3 type canisters deposited in horizontal tunnels. Smaller canisters are to be deposited in deep bore holes at a depth between 2000 to 4000 m in the Very Deep Holes (VDH) concept. In all concepts the canisters will be surrounded by a bentonite buffer. The aim of the present study is to analyze and compare the performance and long-term safety of the repository concepts. Only a qualitative comparison of the concepts is made as no calculations of radionuclide releases or dose to man have been performed. The ranking of the repository concepts was carried out by comparing the VDH, VLH and MLH concept with the KBS-3 concept. The performance and long-term safety of the repositories located at 500 m level will be based on a multiple barrier system and the predictions for the concepts will involve similar uncertainties.

    Full Text Available There are different places in India where natural stone aggregates are not available for constructional work. Plastic coated OBBA can solve the problem of shortage of stone aggregate to some extent. The engineers are always encouraged to use locally available materials. The present investigation is carried out to evaluate the plastic coated OBBA as an alternative material for bituminous road construction. Shredded waste plastics are mixed with OBBA in different percentages as 0.38, 0.42, 0.46, 0.50, 0.54, and 0.60 of the weight of brick aggregates. Marshall Method of mix design is carried out to find the optimum bitumen content of such bituminous concrete mix prepared by plastic coated OBBA. Bulk density, Marshall Stability, flow, Marshall Quotient, ITS, TSR, stripping, fatigue life, and deformations have been determined accordingly. Marshall Stability value of 0.54 percent of plastic mix is comparatively higher than the other mixes except 0.60 percent of plastic mix. Test results are within the prescribed limit for 0.54 percent of plastic mix. There is a significant reduction in rutting characteristics of the same plastic mix. The fatigue life of the mix is also significantly higher. Thus plastic coated OBBA is found suitable in construction of bituminous concrete road.

    High-dose ketoconazole (400 mg q.d. for ≥5 days) has been the gold-standard strong cytochrome P450 3A (CYP3A) inhibitor in drug development drug-drug interaction (DDI) studies. In 2013, the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) advised against using this ketoconazole regimen following review of clinical safety reports. We systematically evaluated 19 strong CYP3A inhibitors from regulatory guidances and a literature database to identify itraconazole (200 mg b.i.d. on day 1, q.d. on days 2-6) and clarithromycin (500 mg b.i.d. for 7 days) as acceptable ketoconazole alternatives.

    The hyperturbulence in today's health care environment acts as a primer that escalates the frequency and severity of business conflicts. Several alternative dispute resolution (ADR) programs are described, with ADR suggested as a viable approach in assisting organizations in resolving conflicts. The data indicate that all of the health care organizations surveyed utilize some form of ADR to resolve conflict. The most common conflict resolution objective found is win/win, and respondents felt that ADR effectively met intended objectives. While the data gathered for this study are from a limited geographic region in Central Florida, the results can likely be generalized to many socially and ethnically diverse regions of the country.

All new EU countries are involved in the process of implementation of the European Council Directive31/99/EC on the landfill of waste in the European Union. As consequence National legislation, adapted to fit the EUrequirements, focuses on integrated waste management and environmental control of municipal solid waste landfills,from start-up to closure and assimilation into the environment. In Romania, by Government decision, HG 349/2005,was established the obligatoriness of closing unconform waste landfills located in urban areas starting at July 2009. Asconsequence the owner of municipal waste landfill Medias started the proceedings of closure for the landfill. The aim ofthis study is to compare, from an environmental point of view, different alternatives for the closure of the municipalsolid waste landfill Somard-Medias (Romania.

  3. Oxidative degradation of alternative gasoline oxygenates in aqueous solution by ultrasonic irradiation: Mechanistic study

    International Nuclear Information System (INIS)

    Widespread pollution has been associated with gasoline oxygenates of branched ethers methyl tert-butyl ether (MTBE), di-isopropyl ether (DIPE), ethyl tert-butyl ether (ETBE), and tert-amyl ether (TAME) which enter groundwater. The contaminated plume develops rapidly and treatment for the removal/destruction of these ethers is difficult when using conventional methods. Degradation of MTBE, with biological methods and advanced oxidation processes, are rather well known; however, fewer studies have been reported for degradation of alternative oxygenates. Degradation of alternative gasoline oxygenates (DIPE, ETBE, and TAME) by ultrasonic irradiation in aqueous oxygen saturation was investigated to elucidate degradation pathways. Detailed degradation mechanisms are proposed for each gasoline oxygenate. The common major degradation pathways are proposed to involve abstraction of α-hydrogen atoms by hydroxyl radicals generated during ultrasound cavitation and low temperature pyrolytic degradation of ETBE and TAME. Even some of the products from β-H abstraction overlap with those from high temperature pyrolysis, the effect of β-H abstraction was not shown clearly from product study because of possible 1,5 H-transfer inside cavitating bubbles. Formation of hydrogen peroxide and organic peroxides was also determined during sonolysis. These data provide a better understanding of the degradation pathways of gasoline oxygenates by sonolysis in aqueous solutions. The approach may also serve as a model for others interested in the details of sonolysis. - Highlights: ► Gasoline oxygenates (ETBE, TAME, DIPE) were completely degraded after 6 hours under ultrasonic irradiation in O2 saturation. ► The major degradation pathways were proposed to involve abstraction of α-hydrogen atoms by hydroxyl radicals and low temperature pyrolytic degradation. ► The effect of β-H abstraction was not observed possibly because of 1,5 H-transfer inside cavitating bubbles. ► Formation

  4. Mask roughness induced LER control and mitigation: aberrations sensitivity study and alternate illumination scheme

    McClinton, Brittany M.; Naulleau, Patrick P.

    2011-03-11

    Here we conduct a mask-roughness-induced line-edge-roughness (LER) aberrations sensitivity study both as a random distribution amongst the first 16 Fringe Zernikes (for overall aberration levels of 0.25, 0.50, and 0.75nm rms) as well as an individual aberrations sensitivity matrix over the first 37 Fringe Zernikes. Full 2D aerial image modeling for an imaging system with NA = 0.32 was done for both the 22-nm and 16-nm half-pitch nodes on a rough mask with a replicated surface roughness (RSR) of 100 pm and a correlation length of 32 nm at the nominal extreme-ultraviolet lithography (EUVL) wavelength of 13.5nm. As the ideal RSR value for commercialization of EUVL is 50 pm and under, and furthermore as has been shown elsewhere, a correlation length of 32 nm of roughness on the mask sits on the peak LER value for an NA = 0.32 imaging optic, these mask roughness values and consequently the aberration sensitivity study presented here, represent a worst-case scenario. The illumination conditions were chosen based on the possible candidates for the 22-nm and 16-nm half-pitch nodes, respectively. In the 22-nm case, a disk illumination setting of {sigma} = 0.50 was used, and for the 16-nm case, crosspole illumination with {sigma} = 0.10 at an optimum offset of dx = 0 and dy = .67 in sigma space. In examining how to mitigate mask roughness induced LER, we considered an alternate illumination scheme whereby a traditional dipole's angular spectrum is extended in the direction parallel to the line-and-space mask absorber pattern to represent a 'strip'. While this illumination surprisingly provides minimal improvement to the LER as compared to several alternate illumination schemes, the overall imaging quality in terms of image-log-slope (ILS) and contrast is improved.

    The aim of this study is to compare, from an environmental point of view, different alternatives for the management of municipal solid waste generated in the town of Castellón de la Plana (Spain). This town currently produces 207 ton of waste per day and the waste management system employed today involves the collection of paper/cardboard, glass and light packaging from materials banks and of rest waste at street-side containers. The proposed alternative scenarios were based on a combination of the following elements: selective collection targets to be accomplished by the year 2015 as specified in the Spanish National Waste Plan (assuming they are reached to an extent of 50% and 100%), different collection models implemented nationally, and diverse treatments of both the separated biodegradable fraction and the rest waste to be disposed of on landfills. This resulted in 24 scenarios, whose environmental behaviour was studied by applying the life cycle assessment methodology. In accordance with the ISO 14040-44 (2006) standard, an inventory model was developed for the following stages of the waste management life cycle: pre-collection (bags and containers), collection, transport, pre-treatment (waste separation) and treatment/disposal (recycling, composting, biogasification+composting, landfill with/without energy recovery). Environmental indicators were obtained for different impact categories, which made it possible to identify the key variables in the waste management system and the scenario that offers the best environmental behaviour. Finally, a sensitivity analysis was used to test some of the assumptions made in the initial life cycle inventory model. PMID:20381331

    Full Text Available Globally, blended learning (BL technologies have been increasingly applied in a variety of fields, both public and private sectors. In recent years, universities, public and private businesses and organizations are among those employing blended learning methods and technologies in training and re-training of professionals in the workforce. In Malaysia, the increasing use of blended learning to enhance learning and enriching of soft skills among professionals and individuals in the work place is evident. The advancement of technology is an onset to many new avenues and tool for learning and teaching, and it is the coalescing of these various technologies with particular pedagogy or andragogy has helped to popularize BL. However, when an institution makes the critical choice of delivery methods, it is pertinent that the university needs to consider various success factors. One in particular is student-centered approach that entails the need to understand the students as the beneficiary of learning, and the support system they need to help them learn. This qualitative study reports in detail the experience of a small group of students undertaking Executive Diplomas at Executive Development Centre (EDC, Universiti Utara Malaysia as they progress through their Executive program. This paper looks at learning experiences as described by the learners- it is their story, their experience, and their perspective. This study suggests that BL offered a comfortable middle ground, and has lots of potential in higher education in Malaysia. It is a pedagogical alternative that could play a significant role not only for teaching Business Communication, but has the potential to promote lifelong learning initiatives in Malaysia in a much meaningful and inviting way. Although this study shows that BL contributed a significant and meaningful learning particularly for adult learners, it needs more definitive studies. Such information can be used to guide policy makers

    Body height decreases throughout the day due to fluid loss from the intervertebral disk. This study investigated whether spinal shrinkage was greater during workdays compared with nonwork days, whether daily work stressors were positively related to spinal shrinkage, and whether job control was negatively related to spinal shrinkage. In a consecutive 2-week ambulatory field study, including 39 office employees and 512 days of observation, spinal shrinkage was measured by a stadiometer, and calculated as body height in the morning minus body height in the evening. Physical activity was monitored throughout the 14 days by accelerometry. Daily work stressors, daily job control, biomechanical workload, and recreational activities after work were measured with daily surveys. Multilevel regression analyses showed that spinal disks shrank more during workdays than during nonwork days. After adjustment for sex, age, body weight, smoking status, biomechanical work strain, and time spent on physical and low-effort activities during the day, lower levels of daily job control significantly predicted increased spinal shrinkage. Findings add to knowledge on how work redesign that increases job control may possibly contribute to preserving intervertebral disk function and preventing occupational back pain. PMID:24099165

    We evaluated the labeling stability of several alternative meals that could be used to perform solid-phase gastric emptying study. Cooked egg whites labeled with technetium-99m sulfur colloid served as a control. Packaged instant oatmeal and instant mashed potatoes were prepared by adding hot water. Cheddar cheese was melted. Peanut butter was added to bread. The different meals were mixed with technetium-99m sulfur colloid (2.2-3.7 MBq), chopped into small pieces and placed in a glass tube containing gastric juice. Four samples of each meal were analyzed after 1 and 4 h of agitation with a 3-D rotator (two samples per time point). The meal samples were washed with 2 ml of saline and filtered using a blood transfusion filter. The activity in each sample before and after filtering was assayed in a dose calibrator. The percentage of initial radioactivity remaining with the meal of admixture with gastric juice was measured and the average of the two samples was taken. The percentage of activity bound to the solid phase was 98.2+/-1.9, 95.6+/-1.1, 62.1+/-1.7, 41.8+/-0.6, and 74.5+/-3.8% at 1 h and 98.5+/-1.0, 95.8+/-2.6, 77.2+/-6.8, 55.5+/-3.4 and 40.2+/-22.1 at 4 h for egg whites, cheese, oatmeal, mashed potatoes and peanut butter respectively. For egg whites and cheese, there was no significant difference between the values at 1 and 4 h (P>0.8). Cheddar cheese provides an alternative meal for assessing solid gastric emptying in children comparable to egg whites. Oatmeal and mashed potatoes had low and variable labeling stability and are not recommended. In view of the significant proportion of pediatric patients who refuse to eat scrambled eggs or have allergy to eggs, the availability of other meal choices is essential. The versatility of cheddar cheese, which can be added to macaroni or as a topping on pizza, makes it a useful alternative to labeled eggs. PMID:20145582

    Purpose To longitudinally investigate (1) whether lower work ability and work engagement predict the use of company policies on reduced working hours and exemption from evening/night work among older workers, and (2) whether using such policies subsequently contribute to higher work ability and work engagement. Methods In total 6922 employees (45-64 years) participating in the first three waves of the Study on Transitions in Employment, Ability and Motivation were included. Participants yearly filled out an online questionnaires. Regression analyses were applied to study the influence of baseline work ability and work engagement on the incident use of policies during the first year of follow-up, and the incident use of these policies on work ability and work engagement during the second year of follow-up. Results Employees with a higher work ability were less likely to start using the policy 'reduced working hours' [OR 0.91 (95 % CI 0.83-0.98)]. Starting to use this policy was in turn related to lower work ability 1 year later [B -0.28 (95 % CI -0.47 to -0.08)]. Starting to use the policy 'exemption from evening/night work' was related to higher work engagement 1 year later [B 0.23 (95 % CI 0.07-0.39)]. Conclusions Low work ability precedes the use of some company policies aiming to support sustainable employability of older workers. Further research is needed to explore whether company policies result in a (longstanding) improvement, or reduced deterioration, of older workers' employability. PMID:26250870

The alternative ways were presented to the teachers for the Social Studies lessons by examining the samples in the literature in this direction. This study is in the literature scanning model. Today’s students shall face with more complicated economy subjects while making the decisions that will affect their lives when they became adults. The individuals not literate economically and who are void of applying the economic judgment skills, shall consider the economic problems faced by them when both they were young and also they became adults complicated and threatening. The young people can understand the global economy only when learned the economy subjects and thus they have roles much better in their country’s economic system. Therefore it is quite important for today’s young people to understand how the economy affects the humans’ lives in the triangle of the producer, consumer and good citizen. The activities to be applied by the teachers in the Social Studies lessons while they teach the economy subjects, shall help to the teachers to learn the economy subjects seem hard and complicated in both enjoyable and also permanent ways.

    Posttraumatic stress disorder (PTSD) is a highly debilitating and prevalent psychological disorder. It is characterized by highly distressing intrusive trauma memories that are partly explained by fear conditioning. Despite efficient therapeutic approaches, a subset of PTSD patients displays spontaneous recurrence of traumatic memories after successful treatment. The development of animal behavioral models mimicking the individual variability in treatment outcome for PTSD patients represent therefore an important challenge as it allows for the identification of predicting factors of resilience or susceptibility to relapse. However, to date, only few animal behavioral models of long-lasting fear recovery have been developed and their predictive validity has not been tested directly. The objectives of this study were twofold. First we aimed to develop a simple animal behavioral model of long-lasting fear recovery based on auditory cued fear conditioning and extinction learning, which recapitulates the heterogeneity of fear responses observed in PTSD patients after successful treatment. Second we aimed at testing the predictive validity of our behavioral model and used to this purpose a translational approach based (i) on the demonstration of the efficiency of Eye Movement Desensitization and Reprocessing (EMDR) therapy to reduce conditioned fear responses in PTSD patients and (ii) on the implementation in our behavioral model of an electrical bilateral alternating stimulation of the eyelid which mimics the core feature of EMDR. Our data indicate that electrical bilateral alternating stimulation of the eyelid during extinction learning alleviates long-lasting fear recovery of conditioned fear responses and dramatically reduces inter-individual variability. These results demonstrate the face and predictive validity of our animal behavioral model and provide an interesting tool to understand the neurobiological underpinnings of long-lasting fear recovery.

    Full Text Available The personality of an entrepreneur plays an important role on the success of creating new ideas. There are different characteristics such as courage, hardness, braveness, which could help an entrepreneur reach his/her goals. In this paper, we present an empirical study to learn more about students who are supposed to act as entrepreneur to create jobs in different fields of accounting, computer science, mechanical engineering, etc. In this paper, There are seven aspects of accepting reasonable risk, locus of control, the need for success, mental health conditions, being pragmatic, tolerating ambiguity, dreaming and the sense of challenging in our study to measure the level of entrepreneurship. We implement ANOVA test to measure different entrepreneurship characteristics of students who study in various educational fields. The case study is associated with Sama private university located in city of Zanjan/Iran. The results indicate that there are not meaningful differences among pairwise comparison of many engineering fields.

    Models of host–pathogen interactions are crucial for the analysis of microbial pathogenesis. In this context, invertebrate hosts, including Drosophila melanogaster (fruit fly), Caenorhabditis elegans (nematode) and Galleria mellonella (moth), have been used to study the pathogenesis of fungi and bacteria. Each of these organisms offers distinct benefits in elucidating host–pathogen interactions. In this study,we present a newinvertebrate infection model to study fungal infections: the Tenebrio molitor (beetle) larvae. Here we performed T. molitor larvae infection with one of two important fungal human pathogens, Candida albicans or Cryptococcus neoformans, and analyzed survival curves and larva infected tissues.We showed that increasing concentrations of inoculum of both fungi resulted in increased mortality rates, demonstrating the efficiency of the method to evaluate the virulence of pathogenic yeasts. Additionally, following 12 h post-infection, C. albicans formsmycelia, spreading its hyphae through the larva tissue,whilst GMS stain enabled the visualization of C. neoformans yeast and theirmelanin capsule. These larvae are easier to cultivate in the laboratory than G. mellonella larvae, and offer the same benefits. Therefore, this insect model could be a useful alternative tool to screen clinical pathogenic yeast strainswith distinct virulence traits or different mutant strains. PMID:26453946

    This study focuses on the remediation methods and technologies applicable for use at 200-PO-I Groundwater Operable Unit (OU) at the Hanford Site. The 200-PO-I Groundwater au requires groundwater remediation because of the existence of contaminants of potential concern (COPC). A screening was conducted on alternative technologies and methods of remediation to determine which show the most potential for remediation of groundwater contaminants. The possible technologies were screened to determine which would be suggested for further study and which were not applicable for groundwater remediation. COPCs determined by the Hanford Site groundwater monitoring were grouped into categories based on properties linking them by remediation methods applicable to each COPC group. The screening considered the following criteria. (1) Determine if the suggested method or technology can be used for the specific contaminants found in groundwater and if the technology can be applied at the 200-PO-I Groundwater au, based on physical characteristics such as geology and depth to groundwater. (2) Evaluate screened technologies based on testing and development stages, effectiveness, implementability, cost, and time. This report documents the results of an intern research project conducted by Mathew Dado for Central Plateau Remediation in the Soil and Groundwater Remediation Project. The study was conducted under the technical supervision of Gloria Cummins and management supervision of Theresa Bergman and Becky Austin.

  6. Alternative Exercise Technologies to Fight against Sarcopenia at Old Age: A Series of Studies and Review

    2012-01-01

    Full Text Available The most effective physiologic mean to prevent sarcopenia and related muscle malfunction is a physically active lifestyle, or even better, physical exercise. However, due to time constraints, lack of motivation, or physical limitations, a large number of elderly subjects are either unwilling or unable to perform conventional workouts. In this context, two new exercise technologies, whole-body vibration (WBV and whole-body electromyostimulation (WB-EMS, may exhibit a save, autonomous, and efficient alternative to increase or maintain muscle mass and function. Regarding WB-EMS, the few recent studies indeed demonstrated highly relevant effects of this technology on muscle mass, strength, and power parameters at least in the elderly, with equal or even higher effects compared with conventional resistance exercise. On the contrary, although the majority of studies with elderly subjects confirmed the positive effect of WBV on strength and power parameters, a corresponding relevant effect on muscle mass was not reported. However, well-designed studies with adequate statistical power should focus more intensely on this issue.

However, relaxing the design premises in this way would require additional sensitivity analyses. Further, the assessment in SR-Site indicates that the reference design is appropriate for the purpose. However, if the the design premises are relaxed, more robust designs might be worth investigating. This has been studied and the results are presented in this report. Research and development specifically focused on technology for repository closure has not yet been carried out. On the other hand, SKB and other organisations have for many years studied and conducted considerable research on backfilling and sealing of deposition tunnels, including full-scale tests. SKB has also developed and tested technology for sealing of investigation boreholes. Experience and results from these efforts comprise an important basis for this project. The work has focused on sealing of shafts, ramp and investigation boreholes. Alternatives for top sealing and sealing of the central area have not been studied, since their impact on the flow through the repository is judged to be marginal. Nor have alternative concepts for sealing of main and transport tunnels been developed, since it is believed that filling with blocks and pellets of swelling clay is the only alternative that ensures sufficiently low hydraulic conductivity.

  14. A case study of small hydro and grid extension for rural electrification alternatives and complementarities

    International Nuclear Information System (INIS)

    This paper reports that rural electrification in Eastern and Southern African Countries (ESAC) has so far been based largely on stand-alone diesel electric generating plant or on the extension of high-voltage transmission grids fed by large hydro and/or thermal electric generating stations. The alternative of furnishing supply at modest investment and competitive cost from a nearby small- hydro plant has rarely been considered in those countries of the sub-region that have ample hydro-power resources. All countries in the sub-region (except Angola) import petroleum and/or petroleum product supplies, as well as all hardware for electricity supply and utilization. As a result, in most countries an acute shortage of foreign exchange severely hampers implementation of rural electrification schemes. This should turn attention increasingly to strategies which are less capital-intensive and less dependent on foreign exchange, such as small-hydro plants, where the resource is located near to rural demand. Increasing the local content of small-hydro project implementation has paid off in recent years, considerably reducing costs in a number of Asian and Latin American projects. Local contributions have taken the form of resource assessment at a particular site, design, construction works, and fabrication of relatively simple components of power plant such as hydraulic equipment, low pressure penstocks and gates, as well as simpler types of turbines (e.g., the Banki type). Inadequacy of indigenous technical capacity to make similar local contributions in the ESAC has meant that the few recent small-hydro projects have relied on importing both expertise and equipment. The high costs resulting have frequently fueled arguments against pursuit of small-hydro projects

  15. Hexanoic acid as an alternative diluent in a GANEX process. Feasibility study

    International Nuclear Information System (INIS)

    Used nuclear fuel is radiotoxic for mankind and its environment for a long time. However, if it can be transmuted, the radiotoxicity as well as its heat load are reduced. Before a transmutation the actinides within the used fuel need to be separated from the fission, corrosion and activation products. This separation can be achieved by using the liquid-liquid extraction technique. One extraction process that can be used for such a separation is the Group ActiNide EXtraction (GANEX) process. One GANEX process that can successfully accomplish the separation utilizes the diluent cyclohexanone in combination with the extractant tributylphosphate (TBP) (30 % vol) and a second extractant, CyMe4-BTBP (10 mM). However, there are some issues when using cyclohexanone as diluent. In this work an alternative diluent has therefore been tried in order to determine if it can replace cyclohexanone. The diluent used was hexanoic acid. In a system containing 10-12 mM CyMe4-BTBP and 30 % vol TBP in hexanoic acid with the aqueous phase 4 M HNO3, the distribution ratios for americium and curium are unfortunately low (DAm = 1.1 ± 0.27, D Cm = 1.6 ± 1.81). The concentration of CyMe4-BTBP ligand, the extractant of curium and americium, could unfortunately not be increased, because of limited solubility in hexanoic acid. The distribution ratios for fission, corrosion and activation products were low for most metals; however, cadmium, palladium and molybdenum all unfortunately have distributions ratios above 1. To conclude, low americium and curium extractions indicate that hexanoic acid is not a suitable diluent which could replace cyclohexanone in a GANEX process. (author)

    Smania, G; Baiardi, P; Ceci, A; Magni, P

    2016-01-01

    This study presents a pharmacokinetic‐pharmacodynamic based clinical trial simulation framework for evaluating the performance of a fixed‐sample Bayesian design (BD) and two alternative Bayesian sequential designs (BSDs) (i.e., a non‐hierarchical (NON‐H) and a semi‐hierarchical (SEMI‐H) one). Prior information was elicited from adult trials and weighted based on the expected similarity of response to treatment between the pediatric and adult populations. Study designs were evaluated in terms of: type I and II errors, sample size per arm (SS), trial duration (TD), and estimate precision. No substantial differences were observed between NON‐H and SEMI‐H. BSDs require, on average, smaller SS and TD compared to the BD, which, on the other hand, guarantees higher estimate precision. When large differences between children and adults are expected, BSDs can return very large SS. Bayesian approaches appear to outperform their frequentist counterparts in the design of pediatric trials even when little weight is given to prior information from adults. PMID:27530374

    2016-06-01

    Phthalates, used in medical devices (MDs), have been identified as reproductive and developmental toxicants. Their toxicity varies somewhat depending on the specific phthalate and is in part linked to the activation of Peroxisome Proliferating-Activated Receptors (PPARs). So, the use of MDs containing targeted phthalates such as di(2-ethylhexyl) phthalate (DEHP) has been challenged by European directive 2007/47/EC. Therefore, MDs manufacturers were forced to quickly find replacement plasticizers. However, very little toxicological and epidemiological studies are available on human health. So, we proceeded to dock these chemicals in order to identify compounds that are likely to interact with PPARs binding sites. The results obtained are generally very mixed on the harmlessness of these alternatives. Moreover, no data exist on the biological effects of their possible metabolites. As DEHP toxicity resulted mainly from its major metabolites, generalizing the use of these plasticizers without conducting extensive studies on the possible effects on human health of their metabolites seems inconceivable.

  8. Subcritical monitoring studies in BZD/2 using alternative absorber compositions and a localised neutron source

    International Nuclear Information System (INIS)

    A series of supplementary subcritical monitoring studies has been carried out in the Single Annular Core BZD/2. The first part concerned the use of alternative absorber compositions: 40 % enriched B4C and Eu2O3. The worth of the 40 % enriched B4C absorber relative to the naturally enriched one was found to be significantly lower than for the corresponding measurements in the conventional core BZB (1.197 versus 1.259). Although an influence of the harder spectrum in BZD is likely, the results of similar studies in BZC seem to contradict this assumption. Within the experimental errors, the worth of the Eu2O3 absorber relative to natural B4C agrees with that found in BZB. As in previous investigations, diffusion theory calculations were found to overestimate the worth of the 40 % enriched B4C absorber relative to the natural one by several percent. The worth of Eu2O3 relative to B4C-nat was again severely underpredicted. In a second series of experiments, a localised neutron source (Cf-252) was introduced into the core. For the two absorber arrays established in the presence of the source, the MSM analysis produced reactivities, which agree within about 0.5 % relative with those, obtained from previous measurements of these arrays without the localised source. This confirms the satisfactory performance of the MSM technique even in a strongly decoupled annular system with very irregular source distribution

    The fascicular composition and organisation of the inferior alveolar nerve (IAN) were determined to confirm the microarchitecture of the IAN bundles into each of the mandibular teeth, including the composition of the mental nerve. The aim of this study was to evaluate peripheral nerve repair after the application of an antioxidant compound to the damaged nerve tissue to elevate the concentration and bioavailability of elements capable of favouring tissue repair. Twenty-five Wistar rats were divided into groups: The Control 1 (Ctl 1) (n = 5) animals had the ischiatic nerve exposed with no suture injury and were sacrificed at 30 days post-operatively. The Control 2 (Ctl 2) (n = 10) animals had the ischiatic nerve exposed, and the nerve was injured using suture in three distinct regions. In the experimental (Exp) animals (n = 10), an antioxidant organic compound was applied to the nerve injury site. The animals with nerve injury (Ctl2 and Exp group) were sacrificed at 15 and 30 days post-operatively. The histological analysis showed less degeneration in the Exp group at 15 and 30 days post-operatively. Nerve neoformation forming a connection between the distal and proximal suture sites was observed in the experimental group. This study presented an alternative to nerve repair using an antioxidant compound. PMID:25578694

    Full Text Available Teenagers are believed the people who are supposed to build the world's future. High-risk behaviors such as addiction to drugs, smoking cigarettes, sex, etc. could significantly hurts teenagers and there must be some supporting programs to reduce these issues as much as possible. This paper performs an empirical investigation to study the different factors influencing high- risk behavior among teenagers who live in a city of Esfahan, Iran. The proposed study designs a questionnaire and distribute between two groups of female and male teenagers. The results indicate that while there is a meaningful relationship between high-risk behaviors and average high school marks among male students there is no meaningful relationship between high-risk behaviors and high school grades among female students. The results also indicate that there is a meaningful difference between gender and high-risk behavior. The season of birth for female and male students is another important factor for having high-risk behaviors. While the order of birth plays an important role among male students, the order of birth is not an important factor among female teenagers. Finally, the results indicate that teenagers' parental financial affordability plays a vital role on both female and male teenagers.

  14. Work station for low temperature positron annihilation studies

    International Nuclear Information System (INIS)

    This report describes the automation implemented in the low temperature Positron Annihilation Spectroscopy studies system. Temperature programmer and controller (Lakeshore 330) is interfaced to PC-AT through an IEEE-488 add-on card. Through this data can be read and written to the temperature controller and it can be handled remotely. The PC- AT also houses the PCA-II card. Software (TEMP330.EXE) was developed to communicate with the temperature controller. A master software is also developed under which TEMP330.EXE and PCAII.EXE should run. Another program DATASEG.EXE creates a user file to store the temperature points given by user over which data acquisition is required. This has not only widened the scope of the positron research, but also helps achieve result with better precision. (author)

    The structure of a family of copolyimides in which are alternating stiff/redox pyromellitimide units and flexible/solvating polyethyleneoxide (PEO) strands were studied by using wide angle and small angle X-ray scattering techniques and is fully discussed. It is shown that the rich variety of structures exhibited by these compounds can be understood by considering the dramatic change of flexibility of the chain induced by the variation of the length of the PEO strand compared to that of the pyromellimide segment. In this respect, concerning the compounds which exhibit fully amorphous structures a better understanding of their structural behavior can be obtained in the framework of Flory's theory of semi-rigid polymers. In this approach, the degree of flexibility of the chain is mainly resulting from the relative amount of flexible units constituting the repetition unit of the polymer chain. The final structural mode adopted by each compound in the solid state is then directly a consequence of this intrinsic property of the chain. The introduction of a lithium salt in contact with the copolymer chains induces some structure changes which can also be explained by the modification of the degree of flexibility of the chain. It is found that the best performances in terms of electroactivity and mixed conduction are precisely obtained with the only compound which keeps full amorphicity in absence and in presence of the lithium salt.

    Solubility testing with simulated High Level Waste tank heel solids has been conducted in order to evaluate two alternative chemical cleaning technologies for the dissolution of sludge residuals remaining in the tanks after the exhaustion of mechanical cleaning and sludge washing efforts. Tests were conducted with non-radioactive pure phase metal reagents, binary mixtures of reagents, and a Savannah River Site PUREX heel simulant to determine the effectiveness of an optimized, dilute oxalic/nitric acid cleaning reagent and pure, dilute nitric acid toward dissolving the bulk non-radioactive waste components. A focus of this testing was on minimization of oxalic acid additions during tank cleaning. For comparison purposes, separate samples were also contacted with pure, concentrated oxalic acid which is the current baseline chemical cleaning reagent. In a separate study, solubility tests were conducted with radioactive tank heel simulants using acidic and caustic permanganate-based methods focused on the “targeted” dissolution of actinide species known to be drivers for Savannah River Site tank closure Performance Assessments. Permanganate-based cleaning methods were evaluated prior to and after oxalic acid contact.

    2007-03-01

    The study of high-k dielectrics and metal gate electrodes is critical to next generation MOSFETs. We have measured the band offsets of alternative MOS stacks using photoemission and inverse photoemission in the same chamber as well as synchrotron photoemission. At Rutgers, we have measured the valence and conduction band densities of states (DOS) and edges with UV photoemission and inverse photoemission, respectively, in situ. Using synchrotron photoemission we have measured the core level positions as well as the valence band DOS of clean and metallized dielectric/Si systems. The measurement of the chemical shifts of the core levels upon metallization enables us to evaluate the conduction band offset at the metal/dielectric interface. For Hf(x)Si(1-x)O(2), we find the conduction band offset (CBO) does not change as x is varied from 1 to 0.8, but the valence band offset increases by 0.4 eV. Titanium, aluminum and ruthenium were chosen as gate metals because of their prospective use as low and high workfunction metals in dual metal gate CMOS devices. We measured the CBO for the Ti, Al and Ru/Hf(x)Si(1-x)O(2) interfaces and found barriers involving Ti and Ru to be in good agreement with the interface gap state model, whereas the barrier involving Al deviated substantially from it due to the formation of an AlO(X) layer at the interface.

    2011-10-01

    Full Text Available Abstract Background Complementary and alternative medicines (CAMs are being used increasingly across the world. In Australia, community pharmacists are a major supplier of these products but knowledge of the products and interactions with other medicines is poor. Information regarding the use of CAMs by metropolitan pharmacists has been documented by the National Prescribing Service (NPS in Australia but the views of rural/regional community pharmacists have not been explored. The aim of this pilot study was to explore the knowledge, attitudes and information seeking of a cohort of rural community pharmacists towards CAMs and to compare the findings to the larger NPS study. Methods A cross sectional self-administered postal questionnaire was mailed to all community pharmacists in one rural/regional area of Australia. Using a range of scales, data was collected regarding attitudes, knowledge, information seeking behaviour and demographics. Results Eighty eligible questionnaires were returned. Most pharmacists reported knowing that they should regularly ask consumers if they are using CAMs but many lacked the confidence to do so. Pharmacists surveyed for this study were more knowledgeable in regards to side effects and interactions of CAMs than those in the NPS survey. Over three quarters of pharmacists surveyed reported sourcing CAM information at least several times a month. The most frequently sought information was drug interactions, dose, contraindications and adverse effects. A variety of resources were used to source information, the most popular source was the internet but the most useful resource was CAM text books. Conclusions Pharmacists have varied opinions on the use of CAMs and many lack awareness of or access to good quality CAMs information. Therefore, there is a need to provide pharmacists with opportunities for further education. The data is valuable in assisting interested stakeholders with the development of initiatives to

  4. Study of Gasohol as Alternative Fuel for Gasoline Substitution: Characteristics and Performances

    Directory of Open Access Journals (Sweden)

    Full Text Available Gasohol is a mixture of premium petrol (gasoline with alcohol, in this case ethanol. The use of gasohol can reduce fuel consumption without having to modify the existing engine. Therefore, this research is conducted to study the characteristics and performance of gasohol in various mixing ratios, which includes analysis of physical properties and the use of gasohol in the machine. Results show that the addition of technical ethanol at 7.0169%v increases the value of gasohol vapor pressure on the value of 8.6682 psi (7.7 psi for regular gasoline. Gasohol with technical ethanol content above 30%v decreases vapor pressure, promotes phase separation, and causes a sharp drop in temperature from 40%v distillation. In term of corrosivity, gasohol with up to 50%v ethanol content has the same corrosion level with regular gasoline, which is corrosion level 1A. Based on gasohol characteristics test, it is known that gasohol with technical ethanol content below 20%v can be used as a fuel substitute for gasoline. Real-time performance test of gasohol in engines has shown that the addition of ethanol content in gasohol tend to increase the engine power at a certain compression ratio, but it also increases fuel consumption because the heat value of ethanol is lower than gasoline. Machine in gasohol with ethanol content below 20%v can operate smoothly without having to modify the engine. Based on the studies that have been done, gasohol in the range of 10%v ethanol content is well-functioned as a substitute for gasoline fuel and meets fuel specifications required by the General Director of Oil and Gas. The feasibility of using gasohol as an alternative fuel can be studied further.

    Full Text Available Abstract Background Many people with chronic nonspecific musculoskeletal pain (CMP have decreased work ability. The majority, however, stays at work despite their pain. Knowledge about workers who stay at work despite chronic pain is limited, narrowing our views on work participation. The aim of this study was to explore why people with CMP stay at work despite pain (motivators and how they manage to maintain working (success factors. Methods A semi-structured interview was conducted among 21 subjects who stay at work despite CMP. Participants were included through purposeful sampling. Interviews were audio-recorded, transcribed verbatim, and imported into computer software Atlas.ti. Data was analyzed by means of thematic analysis. The interviews consisted of open questions such as: "Why are you working with pain?" or "How do you manage working while having pain?" Results A total of 16 motivators and 52 success factors emerged in the interviews. Motivators were categorized into four themes: work as value, work as therapy, work as income generator, and work as responsibility. Success factors were categorized into five themes: personal characteristics, adjustment latitude, coping with pain, use of healthcare services, and pain beliefs. Conclusions Personal characteristics, well-developed self-management skills, and motivation to work may be considered to be important success factors and prerequisites for staying at work, resulting in behaviors promoting staying at work such as: raising adjustment latitude, changing pain-coping strategies, organizing modifications and conditions at work, finding access to healthcare services, and asking for support. Motivators and success factors for staying at work may be used for interventions in rehabilitation and occupational medicine, to prevent absenteeism, or to promote a sustainable return to work. This qualitative study has evoked new hypotheses about staying at work; quantitative studies on staying at

  16. Conceptual design report: Nuclear materials storage facility renovation. Part 6, Alternatives study

    International Nuclear Information System (INIS)

    The Nuclear Materials Storage Facility (NMSF) at the Los Alamos National Laboratory (LANL) was a Fiscal Year (FY) 1984 line-item project completed in 1987 that has never been operated because of major design and construction deficiencies. This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. Based on current projections, existing storage space for SNM at other locations at LANL will be loaded to capacity by approximately 2002. This will adversely affect LANUs ability to meet its mission requirements in the future. The affected missions include LANL's weapons research, development, and testing (WRD ampersand T) program; special materials recovery; stockpile survelliance/evaluation; advanced fuels and heat sources development and production; and safe, secure storage of existing nuclear materials inventories. The problem is further exacerbated by LANL's inability to ship any materials offsite because of the lack of receiver sites for material and regulatory issues. Correction of the current deficiencies and enhancement of the facility will provide centralized storage close to a nuclear materials processing facility. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public. This report is organized according to the sections and subsections outlined by Attachment 111-2 of DOE Document AL 4700.1, Project Management System. It is organized into seven parts. This document, Part VI - Alternatives Study, presents a study of the different storage/containment options considered for NMSF

    The objective of this project is to conduct research to determine the feasibility of using alternate fuel sources for the production of cement. Successful completion of this project will also be beneficial to other commercial processes that are highly energy intensive. During this report period, we have completed all the subtasks in the preliminary survey. Literature searches focused on the types of alternative fuels currently used in the cement industry around the world. Information was obtained on the effects of particular alternative fuels on the clinker/cement product and on cement plant emissions. Federal regulations involving use of waste fuels were examined. Information was also obtained about the trace elements likely to be found in alternative fuels, coal, and raw feeds, as well as the effects of various trace elements introduced into system at the feed or fuel stage on the kiln process, the clinker/cement product, and concrete made from the cement. The experimental part of this project involves the feasibility of a variety of alternative materials mainly commercial wastes to substitute for coal in an industrial cement kiln in Lafarge NA and validation of the experimental results with energy conversion consideration.

    There is currently no large-scale production of 238Pu in the United States. Feasibility studies were performed at the Idaho National Laboratory to assess the capability of developing alternative 238Pu production strategies. Initial investigations indicate potential capability to provision radioisotope-powered systems for future space exploration endeavors. For the short term production of 238Pu, sealed canisters of dilute 237Np solution in nitric acid could be irradiated in the Advanced Test Reactor (ATR). Targets in the large and medium “I” positions of the ATR were irradiated over a simulated period of 306 days and analyzed using MCNP5 and ORIGEN2.2. Approximately 0.5 kg of 238Pu could be produced annually in the ATR with purity greater than 92%. Optimization of the irradiation cycles could further increase the purity to greater than 98%. Whereas the typical purity of space batteries is between 80 to 85%, the higher purity 238Pu produced in the ATR could be blended with existing lower-purity inventory to produce useable material. Development of irradiation methods in the ATR provides the fastest alterative to restart United States 238Pu production. The analysis of 238Pu production in the ATR provides the technical basis for production using TRIGA® (Training, Research, Isotopes, General Atomics) nuclear reactors. Preliminary analyses envisage a production rate of approximately 0.7 kg annually using a single dedicated 5-MW TRIGA reactor with continuous flow loops to achieve high purity product. Two TRIGA reactors represent a robust means of providing at over 1 kg/yr of 238Pu annually using dilute solution targets of 237Np in nitric acid. Further collaboration and optimization of reactor design, radiochemical methods, and systems analyses would further increase annual 238Pu throughput, while reducing the currently evaluated reactor requirements.

    Full Text Available Fibromyalgia syndrome (FMS is a complex disorder, with primary symptoms of sleep disturbances, pain, and fatigue. FMS is one of the most common reasons for patient visits to a rheumatologist. Previous studies have suggested that complementary and alternative medicine (CAM use in patients with rheumatic diseases is common, but such data specific to FMS patients is limited. Objective: The following study sought to describe the prevalence of CAM use in a primary care practice of patients with FMS and assess whether these patients discuss CAM use with their physician, physician-extender, and/or pharmacist. Methods: A one-group cross-sectional survey design was implemented in a large, community-based, private physician practice of patients diagnosed with FMS. A self-administered questionnaire was distributed during clinic visits. It solicited information related to demographic characteristics; FMS-specific health background; whether CAM use had been discussed with a health care provider; and the “ever-use” of common types of CAM. Respondents returned the questionnaire via US mail in a postage-paid, self-addressed envelope. Results: A total of 115 surveys were distributed with 54 returned for analysis (47% completion rate. The sample was predominantly female, well educated and had a mean age of 55.6 years. All respondents were White. Most respondents (92.6% reported using some type of CAM. Exercise (92.2%, chiropractic treatment (48.1%, lifestyle and diet (45.8%, relaxation therapy (44.9%, and dietary and herbal supplements (36.5% were most commonly reported CAM therapies “ever-used” by respondents. Dietary and herbal supplements with the highest prevalence of “ever-use” were magnesium (19.2%, guaifenesin (11.5%, and methylsulfonylmethane (MSM (9.6%. Respondents most commonly discussed CAM with the clinic rheumatologist and the primary care physician (53.7% and 38.9%, respectively. Only 14.8% of respondents discussed CAM with a pharmacist

    Full Text Available Abstract Background With the increased usage of CAM worldwide comes the demand for its integration into health professional education. However, the incorporation of CAM into health professional curricula is handled quite differently by different institutions and countries. Furthermore, the evaluation of CAM curricula is complicated because students' ability to learn about CAM may be influenced by factors such as student's prior knowledge and motivation, together with the perceptions and attitudes of clinical preceptors. The study aimed to describe the attitudes, perceptions and beliefs of second, third and fourth year pharmacy students towards complementary and alternative medicine (CAM and to explore factors that might affect attitudes such as learning, preceptors and placements. Methods Pharmacy students from a University in South East Queensland, Australia participated in the study. The study consisted of a cross-sectional survey (n = 110 and semi-structured interviews (n = 9. Results The overall response rate for the survey was 75%, namely 50% (36/72 for second year, 77.3% (34/44 for third year and 97.6% (40/41 for fourth year students. Overall, 95.5% of pharmacy students believe that pharmacists should be able to advise patients about CAM and most (93.7% have used CAM prior to course enrolment. Students' attitudes to CAM are influenced by the use of CAM by family, friends and self, CAM training, lecturers and to a lesser degree by preceptors. The majority of pharmacy students (89.2% perceive education about CAM as a core and integral part of their professional degree and favour it over an additional postgraduate degree. However, they see a greater need for education in complementary medicines (such as herbal medicines, vitamins and minerals than for education in complementary therapies (such as acupuncture, meditation and bio-magnetism. Knowledge and educational input rationalised rather than marginalised students' attitudes towards CAM

  6. Alternative crops

    International Nuclear Information System (INIS)

    Surplus cereal production in the EEC and decreasing product prices, mainly for cereals, has prompted considerable interest for new earnings in arable farming. The objective was to examine whether suggested new crops (fibre, oil, medicinal and alternative grains crops) could be considered as real alternatives. Whether a specific crop can compete economically with cereals and whether there is a market demand for the crop is analyzed. The described possibilities will result in ca. 50,000 hectares of new crops. It is expected that they would not immediately provide increased earnings, but in the long run expected price developments are more positive than for cereals. The area for new crops will not solve the current surplus cereal problem as the area used for new crops is only 3% of that used for cereals. Preconditions for many new crops is further research activities and development work as well as the establishment of processing units and organizational initiatives. Presumably, it is stated, there will then be a basis for a profitable production of new crops for some farmers. (AB) (47 refs.)

    Growth of the ornamental fish industry is being hindered by the scarcity of low cost feed; hence alternative protein supplements should be explored. In this context the present study aims to evaluate whether the grasshopper Oxya fuscovittata could be used as a supplement for fish meal in the diets of Poecillia sphenops, which is one of the most common ornamental fishes worldwide. The present work is divided into three phases: In the first phase proximate composition of the grasshopper is obtained and five diets are prepared where fish meal is gradually replaced by Oxya meal and named as control, D1, D2, D3 and D4. All the diets are formulated on iso-nitrogenous basis where the protein percentage is fixed at 400 g/kg. The second phase deals with feeding trial and in the third phase all the data of the feeding trial are subjected to a linear model. The feeding trial shows that the control, D1 and D2 fed fishes have almost similar results. The linear model proves that the variation in the indices are mainly due to replacement of fish meal by Oxya meal, not due to the variations of rice husk and mustard oil cake that are also used to formulate the diets of the present study. From the results two Oxya supplemented diets, i.e. D1 and D2 are proved to be almost equivalent to the control diet. Hence it is concluded that Oxya meal is able to replace 25% to 50% of fish meal from the diets of P. sphenops. PMID:25383946

  19. Technology mix alternatives with high shares of wind power and photovoltaics—case study for Spain

    International Nuclear Information System (INIS)

    The shift to a low carbon society is an issue of highest priority in the EU. For electricity generation, such a target counts with three main alternatives: renewable energies, nuclear power and carbon capture and storage. This paper focuses on the renewables’ alternative. Due to resource availability, a technology mix with a high share of PV and wind power is gaining increasing interest as a major solution for several EU member states and in part for the EU collectively to achieve decarbonization and energy security with acceptable costs. Due to their intermittency, the integration of high shares of PV and wind power in the electricity supply is challenging. This paper presents a techno-economic assessment of technology mix alternatives with a high share of PV and wind power in Spain, as an example. Thereby, the focus is on the option of increasing wind curtailment versus substituting rigid baseload generation in favor of the more flexible gas turbines and combined cycle gas turbines. - Highlights: ► The potential of power generation from renewable energy resources in the EU is illustrated. ► The LEC of the different technologies considered is calculated for today and future scenarios. ► An excel-based model for the technology mix assessment is applied using Spanish data. ► Technology mix alternatives with a high share of PV and wind power are assessed. ► The focus is on increasing wind curtailment vs. relying on more flexible power generation units.

Patients with congenital PAN complain of oscillating vision at high rates. Medication is the first-choice treatment for PAN; however, clinicians still seek better therapy. The aim of this study was to evaluate outcomes of recession of four horizontal rectus muscle (R-FHR in patients with congenital PAN.Patients and methods: This study reports a retrospective case series of ten patients (seven males and three females; mean age 24.4±10.9 with congenital PAN who underwent R-FHR between 2007 and 2012, which was performed by the same surgeon at the Hyogo College of Medicine. Patients were evaluated for complications, recession amount, deviation angle, eye movements including a nystagmus amplitude, and visual acuity during pre- and post-operative periods.Results: Pre-operatively, patients complained of oscillating vision, abnormal head posture, esotropia, and congenital superior oblique palsy. Post-operatively, changes from the previous observations of nystagmus amplitudes and abnormal head posture demonstrated a complete reversal in all patients. In addition, visual acuity determined with a Snellen chart improved in two patients. However, esotropia occurred in three patients who underwent additional strabismus surgery 2 days after R-FHR. R-FHR was particularly effective in eight patients who pre-operatively had periodic oscillating vision with a regular pattern of periodic nystagmus.Conclusion: We demonstrated that ten patients with congenital PAN had improved vision following R-FHR, indicating that R-FHR was an effective procedure, especially in patients

  2. Preliminary study of used cooking oil methyl ester as an alternative fuel for diesel engine

    International Nuclear Information System (INIS)

    An experimental work has been carried out to compare the power performance and exhaust emissions of UCOME with OD on unmodified direct injection, four stroke single cylinder and stationary Robin diesel engine. Used cooking oil was transesterified by using methanol that yields immiscible fraction of glycerol and methyl ester (biodiesel). UCOME was separated by gravity before conducting further testing on its physical, chemical and thermal properties in the laboratory. For fuel power performance analysis, fuel consumption, gross energy input, torque, brake power, BMEP and SFC of the engine were measured and calculated. The analysis showed that at high engine speeds, the engine performances with UCOME are comparable to that of OD. However, UCOME increases specific fuel consumption due to its high specific density. In term of exhaust emissions UCOME showed a net reduction in exhaust emissions of NOx as compared with those of OD. This study has given optimistic information to pave the direction for further research on diesel engine

    The emergence of alternative medicines for AIDS in Asia and Africa was discussed at a satellite symposium and the parallel session on alternative and traditional treatments of the AIDSImpact meeting, held in Marseille, in July 2007. These medicines are heterogeneous, both in their presentation and in their geographic and cultural origin. The sessions focused on the role of these medications in selected resource poor settings in Africa and Asia now that access to anti-retroviral therapy is increasing. The aims of the sessions were to (1) identify the actors involved in the diffusion of these alternative medicines for HIV/AIDS, (2) explore uses and forms, and the way these medicines are given legitimacy, (3) reflect on underlying processes of globalisation and cultural differentiation, and (4) define priority questions for future research in this area. This article presents the insights generated at the meeting, illustrated with some findings from the case studies (Uganda, Senegal, Benin, Burkina Faso, China and Indonesia) that were presented. These case studies reveal the wide range of actors who are involved in the marketing and supply of alternative medicines. Regulatory mechanisms are weak. The efficacy claims of alternative medicines often reinforce a biomedical paradigm for HIV/AIDS, and fit with a healthy living ideology promoted by AIDS care programs and support groups. The AIDSImpact session concluded that more interdisciplinary research is needed on the experience of people living with HIV/AIDS with these alternative medicines, and on the ways in which these products interact (or not) with anti-retroviral therapy at pharmacological as well as psychosocial levels.

    Full Text Available Abstract Background Many women suffer from health problems after giving birth, which can lead to sick leave. About 30% of Dutch workers are on sick leave after maternity leave. Structural contact of supervisors with employees on maternity leave, supported by early medical advice of occupational physicians, may increase the chances of return-to-work after maternity leave. In addition, to understand the process of sick leave and return-to-work after childbirth it is important to gain insight into which factors hinder return-to-work after childbirth, as well, as which prognostic factors lead to the development of postpartum health complaints. In this paper, the design of the Mom@Work study is described. Methods The Mom@Work study is simultaneously a randomised controlled trial and a cohort study. Pregnant women working for at least 12 hours a week at one of the 15 participating companies are eligible to participate. The supervisors of these pregnant employees are randomised at 35 weeks pregnancy into the intervention group or control group. During maternity leave, supervisors in the intervention group contact their employee six weeks after delivery using a structured interview. When employees do not expect to return to their jobs at the end of their scheduled maternity leave due to health problems, the supervisor offers early support of the occupational physician. Supervisors in the control group have no structural contact with their employees during maternity leave. Measurements take place at 30 weeks pregnancy and at 6, 12, 24 and 52 weeks postpartum. In addition, cost data are collected. For the RCT, primary outcome measures are sick leave and return-to-work, and secondary outcome measures are costs, health, satisfaction with intervention and global feelings of recovery. Outcome measures for the cohort are pregnancy-related pelvic girdle pain, fatigue and depression. Finally, a number of prognostic factors for return-to-work and for the

    This paper deals with a current decay characteristics of a high temperature superconducting (HTS) magnet operated in persistent current mode (PCM). In superconducting synchronous machine applications such as linear synchronous motor (LSM), the superconducting coil is designed to operate in the PCM to obtain steady magnetic field with DC transport current. This superconducting magnet operates on a direct current, but it can be exposed to alternating magnetic field due to the armature winding. When the magnet is subjected to an external time-varying magnetic field, it is possible to result in a decay of the current in PCM system due to AC loss. In this research, a PCM system with armature coil which generates time-varying magnetic field was fabricated to verify current decay characteristics by external alternating magnetic field. The current decay rate was measured by using a hall sensor as functions of amplitude and frequency of armature coil.

    There is considerable evidence showing that night work is associated with increased morbidity, but only a few studies have focused on its relation to mortality. This study investigates the relationship between the type of working-time arrangement (weekly night work/daytime work) and total and cause-specific mortality among men and women. The data consist of a representative working conditions survey of Finnish employees conducted in 1984 (2286 men/2216 women), which has been combined with register-based follow-up data from Statistics Finland covering the years 1985-2008. In the 1984 survey, the employees were asked if they worked during the night (23:00-06:00 h) and if so, how often. In this study, the authors compare employees who worked at night (121 men/89 women) to daytime employees who did not do night work (1325 men/1560 women). The relative risk of death was examined by Cox proportional hazards analyses adjusted for background (age, level of education, family situation, and county), health (longstanding illness, pain symptoms, smoking status, and psychological symptoms), and work-related factors (weekly working hours, physical and psychological demands, demands of learning at work, and perceived job insecurity). Female employees working at night had a 2.25-fold higher risk of mortality than female dayworkers (95% confidence interval [CI] 1.20-4.20) after adjustment for background and health- and work-related factors. In addition to total mortality, night work was also associated with tumor mortality. Female night workers had a 2.82-fold higher risk of tumor mortality than female dayworkers (95% CI 1.20-6.65) in the adjusted model. Among men, no such significant association was observed. The present study indicated that female night workers had a higher risk of both total and tumor mortality compared to female daytime employees. Additional research on the potential factors and mechanisms behind the association between night work and mortality is required

  6. Feasibility studies of actinide recycle in LMFBRs as a waste management alternative

    International Nuclear Information System (INIS)

    A strategy of actinide burnup in LMFBRs is being investigated as a waste management alternative to long term storage of high level nuclear waste. This strategy is being evaluated because many of the actinides in the waste from spent-fuel reprocessing have half-lives of thousands of years and an alternative to geological storage may be desired. From a radiological viewpoint, the actinides and their daughters dominate the waste hazard for decay times beyond about 400 years. Actinide burnup in LMFBRs may be an attractive alternative to geological storage because the actinides can be effectively transmuted to fission products which have significantly shorter half-lives. Actinide burnup in LMFBRs rather than LWRs is preferred because the ratio of fission reaction rate to capture reaction rate for the actinides is higher in an LMFBR, and an LMFBR is not so sensitive to the addition of the actinide isotopes. An actinide target assembly recycle scheme is evaluated to determine the effects of the actinides on the LMFBR performance, including local power peaking, breeding ratio, and fissile material requirements. Several schemes are evaluated to identify any major problems associated with reprocessing and fabrication of recycle actinide-containing assemblies. The overall efficiency of actinide burnout in LMFBRs is evaluated, and equilibrium cycle conditions are determined. It is concluded that actinide recycle in LMFBRs offers an attractive alternative to long term storage of the actinides, and does not significantly affect the performance of the host LMFBR. Assuming a 0.1 percent or less actinide loss during reprocessing, a 0.1 percent loss of less during fabrication, and proper recycle schemes, virtually all of the actinides produced by a fission reactor economy could be transmuted in fast reactors

    In Vietnam, most of municipal solid waste (MSW) is disposed of at open dumping and landfill sites, and the methane gas from waste is the un-ignorable source of greenhouse gas (GHG) emission. It is indispensable to explore the possibility for GHG mitigation in MSW management. The objective of this study was to estimate alternative waste treatment practices towards the GHG emission mitigation, energy consumption and generation, reduction of landfill volume, and various benefits for proposing the appropriate selection by scenario analyses for representative Vietnam's cities. Impacts were calculated by utilizing life cycle assessment (LCA) method. A literature review survey on the current applicability of LCA database for assessing impacts from waste sector in developing countries, especially for Vietnam, was carried out. This study assessed the contribution of alternative solid waste treatment practices. The result showed that, except investment and operation costs, incineration with energy recovery seems the suitable alternative for treating waste from representative cities of Vietnam according to reduction of GHG emission and waste burden to landfill sites and energy recovery and generation. Besides, MSW composition was identified as an important factor directly influencing to impacts as well as other products and benefits of waste treatment alternatives. Reliable data on waste composition are indispensable for assessing to choose, improve, or plan the waste treatment practices towards sustainable development. PMID:23475528

  13. Work plan for the remedial investigation/feasibility study-environmental impact statement for the Maywood site, Maywood, New Jersey

    International Nuclear Information System (INIS)

    This work plan has been prepared to document the scoping and planning process performed by the US Department of Energy (DOE) to support remedial action activities at the Maywood site located in northern New Jersey in the boroughs of Maywood and Lodi and the township of Rochelle Park. Remedial action at the Maywood site is being planned as part of DOE's Formerly Utilized Sites Remedial Action Program. The DOE is responsible for controlling the release of all contaminants from the site. Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), a remedial investigation/feasibility study (RI/FS) must be prepared to support the decision-making process for evaluating remedial action alternatives. This work plan contains a summary of information currently known about the Maywood site, presents a conceptual site model that identifies potential routes of human exposure to site contaminants, identifies data gaps, and summarizes the process and proposed studies that will be used to fill the data gaps. In addition, DOE activities must be conducted in compliance with the National Environmental Policy Act (NEPA), which requires consideration of the environmental consequences of a proposed action as part of its decision-making process. It is DOE policy to integrate the requirements of the CERCLA and NEPA processes for remedial actions at sites for which it has responsibility. This work plan also describes the approach that will be used to evaluate potential remedial action alternatives and includes a description of the organization, project controls, and task schedules that will be employed to fulfill the requirements of both CERCLA and NEPA. 150 refs., 26 figs., 17 tabs

    Full Text Available Background: Exposure to Occupational noise is the major avoidable cause of permanent hearing loss that is preventable by protective measures. Present study evaluated hearing profile and effects of shift, sex, and smoking on hearing loss in plastic weavers working in textile industry exposed to impact type of noise. Materials and Methods: A cross-sectional study of hearing threshold of various shift workers of plastic weaving industries (18 males, 32 females at various frequencies was done and effect of various factors was tested at low and high frequencies and compared at 4 kHz, 6 kHz, and 8 kHz statistically. Results: Hearing thresholds were significantly higher at high frequencies than speech frequencies, in day shift workers than night shift workers and within day shift workers more with continuous type of shift work than interrupted type. Females showed better hearing than males and for non-smokers than smokers, but the difference observed in both instances proved statistically insignificant. Conclusion: It can be concluded that the use of alternate day and night shift, interrupted day shift may be used to prevent hearing loss and for further confirmation few more studies are warranted. Being female and non smoking also proved an advantage. Comparatively, mild to moderate degree of hearing loss further reinforces the scope of prevention by hearing protective devices and interrupted shift design of work.

    Full Text Available This study researched how a population of 40 undergraduate students attending a career planning project in a private college perceived work, career and their relation with interpersonal relationships. The questionnaire revealed that most subjects perceived work positively, reported through four different perceptions of work, reported perceiving a social dimension of work, but about half of it reported that they didn’t perceive people in general working in a way that showed being concerned about changing society. When the subjects listed people who worked with the same values they held, reports ranged through parents, bosses and friends; when asked about people that didn’t have the same values, they listed work-mates, peers and siblings; when asked about most important people for their career, they listed their parents separately, teachers and children. Data suggested a wide participation of relationships in processing information and constructing conceptions related to work and career.

    Full Text Available The energy requirement pattern of world is growing up and developing technology. The available sources, while exhausting and not friendly to the environment, are highly used. Looking at partial supply and different options of environment problems associated with usage, renewable energy sources are getting attention. MSW (Municipal solid waste composition data had been collected from 1997 to 2009, in Benghazi Libya, to evaluate the waste enthalpy. An incinerator with capacity of 47,250 kg/h was confirmed to burn all the quantity of waste generated by the city through the next 15 years. Initial study was performed to investigate energy flow and resource availability to insure sustainable MSW required by the incinerator to work at its maximum capacity during the designated period. The primary purpose of the paper is to discuss the design of Rankin steam cycle for the generation of both power (PG and combined heat power (CHP. In the power generation case, the system was found to be able to generate electrical power of 13.1 MW. Including the combined heat power case, the results showed that the system was able to produce 6.8 million m3/year of desalinated water and generate 11.33 MW of electricity. In conclusion, the CHP designed system has the greatest potential to maximize energy saving, due to the optimal combination of heat production and electricity generation.

    Full Text Available Understanding knowledge work and supporting it with information systems (ISs are challenging tasks. Knowledge work has changed substantially recently and studies on how knowledge work is currently performed are scarce. Ethnography is the most suitable qualitative research method for studying knowledge work, yet too time-consuming, costly and unfocused for the fast changing IS domain. Moreover, results from qualitative studies need to be transformed into artefacts useful for IS requirements engineering and design. This paper proposes a procedure for collaborative ethnography to study knowledge work practices and inform IS requirements gathering and design illustrated with the case of a collaborative ethnographic study of seven organisations in four European countries performed in a large-scale international IS research and development project. The paper also critically discusses the procedure’s applicability and limitations.

  12. Copper canister with cast inner component. Amendment to project on Alternative Systems Study (PASS), SKB TR 93-04

    International Nuclear Information System (INIS)

    The Project on Alternative Systems Study, PASS, was described in a report dated october 1992. In the report, the reference repository concept KBS-3 is described together with three other alternatives. In the report several designs for fuel storage canisters are presented. This report describes a recently developed design for the inner component of the composite, steel and copper, canister which is the main alternative in the KBS-3-model. The new design will be manufactured by casting. A cast insert with inner walls eliminates the need for a stabilizing filler in the canister and guarantees that the fuel remains sub-critical during sufficient time in the repository. The cast insert is judged, to, in comparison with the steel tube alternative, lead to a considerably simplified process in the encapsulation plant and lower development and investment cost. Positive side effects of the design are that the mechanical strength is improved by a factor 2-3 and that the difficult filling operation is avoided in the encapsulation process. The drawbacks are higher weight and probably higher unit price for the empty canister

    The present study aimed to advance insight in the associations between employees' daily effort expenditure at work and their recovery state during the workday, and specifically focused on the role of daily work-related need satisfaction in this process. We examined (a) if high intrinsic work motivation and low self-control effort act as mediating mechanisms underlying the beneficial role of need satisfaction, and (b) to what extent need satisfaction mitigates the adverse effects of high job demands (work pressure and cognitive demands) on employee recovery. Data were collected by means of a 5-day daily diary study (2 measurements daily: in the morning before work, and at the end of the workday) among 68 participants. Multilevel analyses showed that need satisfaction at work was related to a beneficial recovery state at the end of the workday, and that this association was mediated by high intrinsic work motivation and low self-control effort. Furthermore, need satisfaction attenuated the adverse effects of high work pressure on employee recovery. All in all, this study increased our understanding of employees' daily effort and recovery processes at work, and highlighted the beneficial role of need satisfaction at work. PMID:25705912

    2007-12-01

    Full Text Available This paper presents the research results of a study that focused on intercultural interaction issues in private sector workplaces in Eastern Finland. The results show that the current challenges caused by the globalisation pressures in the realm of economics behoves work communities to review their personnel training and management practices: the work communities as a whole should be helped to deal with increasing cultural diversity. Although the number of workers with foreign backgrounds has increased in Eastern Finland, so far, there have been only a few attempts to restructure the working practices in an effort to take into account the demands of increasingly diverse working contexts. In all participating companies the mainstream people were the norm. It was common that Finnish language proficiency was seen as a necessary but not yet sufficient qualification for work. In addition, knowledge of the practices of Finnish working life, as well as training and working experience acquired in Finland were desired.

    Full Text Available Abstract Background Breast cancer management has improved dramatically in the past three decades and as a result, a population of working age women is breast cancer survivor. Interventions for breast cancer survivors have shown improvements in quality of life and in physical and psychological states. In contrast, efforts aimed at stimulating re-employment and return-to-work interventions for breast cancer survivors have not kept pace. The objective of this review was to study the effects and characteristics of intervention studies on breast cancer survivors in which the outcome was return to work. Methods The Cochrane Controlled Trials Register (The Cochrane Library, Issue 4, 2006, Medline, Ovid, EMBASE and PsychInfo were systematically searched for studies conducted between 1970 to February 2007. Intervention studies for female breast cancer survivors that were focused on return to work were included. Results Our search strategy identified 5219 studies. Four studies out of 100 potentially relevant abstracts were selected and included 46–317 employed women who had had mastectomy, adjuvant therapy and rehabilitation, with the outcome return to work. The intervention programs focused on improvement of physical, psychological and social recovery. Although a substantial percentage (between 75% to 85% of patients included in these studies returned to work after rehabilitation, it is not clear whether this proportion would have been lower for patients without counseling or exercise, or any other interventions, as three out of four studies did not include a comparison group. Conclusion The most important finding of this review is the lack of methodologically sound intervention studies on breast cancer survivors with the outcome return to work. Using evidence from qualitative and observational studies on cancer and the good results of intervention studies on return to work programs and vocational rehabilitation, return to work interventions for breast

    2013-01-01

    Full Text Available This paper investigated the spacing threshold of nonsubmerged spur dikes with alternate layout to classify the impact scale of spur dikes. A mathematical model was built based on standard k-ε model, finite volume method (FVM, and rigid lid assumption and was verified by experimental data. According to dimensional analysis, three indices, that is, Fr (Froude number, B/b (channel width to dike length, and B/h (channel width to water depth, were identified as the influencing factors on the spacing threshold, based on which fifteen sets of conditions were simulated. The calculation results indicate that B/h is the most influencing parameter on Sc/b (spacing threshold to dike length, followed by B/b and Fr. A dimensionless empirical formula of spacing threshold is fitted by multivariate regression. The results of four sets of additional conditions illustrate that the generalization of empirical formula is satisfactory and the precision of interpolation is higher than that of extrapolation. Furthermore, the spacing threshold of alternate spur dikes is generally smaller than ipsilateral spur dikes.

  9. Comparative study of alternative ORC-based combined power systems to exploit high temperature waste heat

    International Nuclear Information System (INIS)

    Highlights: • Three ORC-based combined systems for ICE exhaust waste heat recovery are studied. • A parametric investigation is conducted under several typical engine conditions. • Performance is evaluated considering six thermodynamic, techno-economic indexes. • DORC distinguishes among other solutions for its highest energy recovery capacity. • TEG–ORC system becomes attractive when exhaust temperature is relatively low. - Abstract: In this paper, various combined power systems which regard organic Rankine cycle (ORC) as bottoming cycle to recover engine’s high temperature exhaust heat are proposed. The topping recovery cycle includes steam Rankine cycle (RC), Brayton cycle (BC) and thermoelectric generator (TEG). Comprehensive evaluations are conducted under five typical engine conditions, ranging from high load to low load, and system performance is assessed in terms of many thermodynamic indexes, such as net output power, thermal efficiency, recovery efficiency and exergy efficiency. Besides that, the irreversibility of each component is also discussed in detail. R123, R245fa and R600a for ORC system are considered to analyze the influence of working fluids. Considering the system techno-economy, the turbine size parameter (SP) and heat transfer capacity (UA) are chosen as key indicators. The results show that compared with the other two investigated approaches, dual-loop ORC (DORC) possesses the highest energy exploitation capacity under the whole operating region, with a 5.57% increase of fuel economy under the rated condition, but its values of SP and UA are large as well. TEG–ORC becomes appealing while under the relatively low load

    2010-12-01

    The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at Florianópolis, SC, Brazil, was studied. The alternative method was less efficient to collect Culicidae and Chironomidae (Wilcoxon test p 0.05) from Aechmea lindenii. This method was less efficient to collect insects of all groups from Vriesea friburgensis (Wilcoxon test p < 0.05). The alternative method was efficient to estimate the diversity of these insects in both species of bromeliads. The higher mobility of immature forms of beetles and dragonflies, and the availability of only one tank in Aechea lindenii, contrasting to several tanks in Vriesea friburgensis that help the suction of these immature, probably influenced the results, which indicated that the suction method should not replace the dismantling in the study of Culicidae and Chironomidae. This method can be useful to get immature forms of Scirtidae and Coenagrionidae in one-tank bromeliads. PMID:21152764

    Full Text Available Abstract Background Older workers have a higher rate and cost of injury than younger workers and with a rapidly ageing work force there is a need to identify strategies to address this problem. Older workers are less physically active and fit than younger workers and so have reduced work ability. The reduced work ability means they are more likely to be fatigued at work and so at greater risk of injury. Exercise could potentially assist this problem. Exercise training has been previously shown to improve fitness in older people however there has been no evaluation of workplace exercise program for older workers. We do not know if the programs are feasible and can improve the fitness and work ability of older workers. We have designed a randomised controlled trial to evaluate whether exercise improves fitness and perceived work-ability of older workers. Methods/Design This paper describes the protocol for a trial examining the effects of a 12-week physical training program in workers over the age of 45. Participants will be randomized to an exercise or no-intervention control group. The primary outcomes are cardiorespiratory endurance, lifting capacity, upper and lower limb strength and perceived work-ability. Discussion This trial will test the feasibility of implementing a worksite-based exercise program as a means of improving the physical fitness and work-ability of older workers performing physically demanding work. If we demonstrate the feasibility of the program we will conduct a larger trial that additionally measures injury outcomes.

    2008-01-01

    This paper is predicated on the view that reductions in work-time are generally desirable. We analyse historical trends in working-hours, the organisation of production, and theories of power and authority in firms and other organisations. Then we consider this in relation to patterns of work in the UK, demonstrating empirically that managers are more wedded to a ‘long-hours’ culture than are other employees. We theorise that this is because managers’ roles align their attitudes with those de...

Use of Complementary and Alternative Medicine for Epileptic Children in Tehran: A Cross-Sectional Study (2009-2011. Iran J Child Neurol. 2014 Winter; 8(1:26-31.ObjectiveAlthough the use of Complementary and Alternative Medicine (CAM has been evaluated globally, there are few studies in our country on this subject. The purpose of this study was to determine the prevalence, pattern of use, parental sources of information, and benefits of CAM in epileptic children in Tehran.Materials & MethodsOne hundred thirty-three parents or relatives of epileptic children who were referred to outpatient clinics or admitted in neurologic ward of four major hospitals in Tehran, were interviewed by our researcher based on a structured questionnaire; from 2009 to 2010. The information obtained comprised the demographic data of patients and their parents, frequency and morphology of convulsions, the type and sources of CAM and finally, the benefits and adverseeffects of this practice.ResultsForty-four percent of the respondents had used CAM methods either alone or in combination with other methods. The most frequently used CAM was written prayers followed by oral herbs and special diets. CAM was mainly introduced to them by relatives. Only 16.7% of these parents had discussed this matter with their children’s physicians. No efficacy to control seizure was observed for most of these methods.ConclusionThis study showed that use of CAM in our study group is relatively common and may have a potentially hazardous role in the treatment process. So, it is necessary for physicians to have enough information about CAM practice in their patients. References:National Institutes of health.

  9. Experimental study of artificial recharge alternatives in northwest Hillsborough County, Florida

    Science.gov (United States)

    Sinclair, William C.

    1977-01-01

    Extensive water withdrawal from the Floridan aquifer in the urban Tampa Bay area has induced leakage from the overlying surficial aquifer adversely effecting the water table and lake levels. Artificial recharge could reduce the impact of these effects. Four experiments were conducted to investigate possible recharge alternatives; sinkhole recharge, water-spreading, connector wells, and subsurface-tile drainage to a deep well. Experiments indicate that all four methods can be effective. However, the sink-hole recharge experiment moved the greatest volume of water into the Floridan aquifer. The drain-tile experiment indicated greatest potential for draining the surficial aquifer. Combinations of the four methods could be used where potential exists for downward movement of water and sufficient unsaturated aquifer for water storage. (Woodard-USGS)

    Full Text Available Abstract Background The objectives of the present study were (1 to track work-life conflict in Switzerland during the years 2002 to 2008 and (2 to analyse the relationship between work-life conflict and health satisfaction, examining whether long-term work-life conflict leads to poor health satisfaction. Methods The study is based on a representative longitudinal database (Swiss Household Panel, covering a six-year period containing seven waves of data collection. The sample includes 1261 persons, with 636 men and 625 women. Data was analysed by multi-level mixed models and analysis of variance with repeated measures. Results In the overall sample, there was no linear increase or decrease of work-life conflict detected, in either its time-based or strain-based form. People with higher education were more often found to have a strong work-life conflict (time- and strain-based, and more men demonstrated a strong time-based work-life conflict than women (12.2% vs. 5%. A negative relationship between work-life conflict and health satisfaction over time was found. People reporting strong work-life conflict at every wave reported lower health satisfaction than people with consistently weak work-life conflict. However, the health satisfaction of those with a continuously strong work-life conflict did not decrease during the study period. Conclusions Both time-based and strain-based work-life conflict are strongly correlated to health satisfaction. However, no evidence was found for a persistent work-life conflict leading to poor health satisfaction.

    2015-10-01

    Full Text Available Fatigue is a symptom of arthritis that causes difficulty at work. An improved understanding of this symptom could assist its management in the work environment. The aim of this study was to explore people with rheumatic diseases’ experiences of fatigue in work. A qualitative descriptive design was used with semi-structured interviews and a constant comparative method of data analysis. There were 18 participants, the majority of them female with Rheumatoid Arthritis (RA and working full-time. Three themes were identified: “Impact of fatigue on work performance” with cognition, mood and physical abilities being the main difficulties reported. In the second theme “Disclosure at Work” participants discussed disclosing their disease to employers but reported a lack of understanding of fatigue from colleagues. The final theme “work-based fatigue management strategies” included cognitive strategies and energy management techniques, which were mainly self-taught. In this study, fatigue was reported to impact on many areas of work performance with limited understanding from colleagues and employers. Interventions from health professionals to assist with development of work-related self-management skills are required to assist with symptom management in the work place. Such interventions should include education to employers and colleagues on the nature of fatigue in Rheumatic diseases.

    2013-12-01

    Self-concordant work motivation arises from one's authentic choices, personal values, and interests. In the present study, we investigated whether self-concordant motivation may fluctuate from one work-related task to the next. On the basis of self-determination theory, we hypothesized that momentary self-concordance buffers the negative impact of momentary work demands on momentary happiness. We developed a modified version of the day reconstruction method to investigate self-concordance, work demands, and happiness during specific work-related tasks on a within-person and within-day level. In total, 132 teachers completed a daily diary on three consecutive work days as well as a background questionnaire. The daily diary resulted in 792 reported work activities and activity-related work demands, self-concordance, and happiness scores. Multilevel analysis showed that-for most work activities-state self-concordant motivation buffered the negative association of work demands with happiness. These findings add to the literature on motivation and well-being by showing that the levels of self-concordance and happiness experienced by employees vary significantly on a within-day level and show a predictable pattern. We discuss theoretical and practical implications of the findings to increase employees' well-being. PMID:24295146

    2007-01-01

    Despite research on work and health having a long-standing concern about unjust exposures and inequitable burdens of disease, there are few studies that document the joint distribution and health effects of physical and psychosocial hazards (e.g., noise, dusts, fumes, and job strain) and social hazards (e.g., racial discrimination and gender harassment) encountered at work. Also, there is a paucity of data on how these exposures, singly and combined, are distributed in relation to sociodemographic characteristics including race/ethnicity, gender, socioeconomic position, and nativity. This article presents a conceptual model for redressing these knowledge gaps and describes recruitment strategies and the characteristics of study participants in the United for Health study. Working with labor unions, the authors recruited 14 (67%) of 21 worksites from manufacturing, meat processing, retail, and transportation, and 1,282 workers (72% response rate), of whom 62 percent were men, 36 percent were women, 39 percent were black, 23 percent were Hispanic, 25 percent were white, 31% earned less than a living wage, 40 percent were below the poverty level, and 23 percent had less than a high school education.

    Full Text Available Communication has a role of heart in all kinds of educational interactions, with the popularization of computer technology for home and office use, teaching methods have changed communication styles from plain lectures to multimedia presentations. These new trends in education are in their infancy, online learning or E-learning, and are quickly becoming an important aspect of education in our future around the world. In spite of easy availability of new multimedia support, still the uses of technological tools of communication in the educational fields are in their initial stages, in the under developing countries like Oman. We have yet to fully experience the transformative effects of these mediums, particularly on web based learning. Group work activities are another main point or task in the high education. Switzer and Shriner [20] were of the view that students are the most obvious party who benefit from group work among students, faculty members, and the community. According to them there are four overlapping types of benefits for students. These are: 1 immediate educational benefits, 2 immediate social benefits, 3 critical thinking benefits, and 4 long-term career benefits. Different researchers were of the opinion that face to face communication will not solve the empowerment problems in group work activities. As, through FTF interaction male dominant role can be produced due to identity of speaker, eye contact, nodding, moving the hands , and facial expressions etc. In this situation suitable adoption of technology can be consider as an alternative mode of communication, where there is a chance of discrimination. This case study will be a further step in addition to the previous technological tools & group work related researches. In this researcher will try to explore that how suitable technological tools can play a role to overcome the group work problems and to increase the performance of the students in the developing countries like

  16. Managing the Work and Family Roles. Does Flexibility Reduce the Negative Interference? An Exploratory Study

    Directory of Open Access Journals (Sweden)

    Cătălina CICEI

    2015-12-01

    Full Text Available Balancing work and family demands has become a great challenge for employees. By providing flexible benefits, organizations actively engage in endeavours aimed at reducing the negative interference between the two life spheres. Even if some empirical studies have examined the effects of family supportive initiatives, focusing on flexibility, however, the findings tend to lack consistency. If flexible benefits are traditionally associated with reduced levels of work-family conflict, in some studies no significant results have been reported. Another line of research suggests that flexibility can actually increase the negative work-family interface. From this perspective, the current study examines the relationship between the flexibility benefits used and work-family conflict, focusing especially on the role flextime and telecommuting. Using flexible benefits is negatively associated with time and strain-based conflict, the effects of flextime and telecommuting varying accordingly to the type of conflict examined. Limitations of the current study andfuture research directions are examined.

    This study aims at 1) examining the effect of self-rostering on emotional demands, quantitative demands, work pace, influence, social community at work, social support from leaders and colleagues, job satisfaction, and negative acts, 2) examining whether this effect was mediated through increased influence on the scheduling of working hours, and interpreting the results in light of the different implementation processes that emerged in the study and by including qualitative data. We conducted a 12 months follow-up, quasi-experimental study of self-rostering among 28 workplaces out of which 14 served as reference workplaces. We also interviewed 26 employees and 14 managers about their expectations of introducing self-rostering. In the present study implementation of self-rostering had a positive effect on job demands and the social environment of the workplace, especially if the intervention does not comprise drastic changes of the organisation of the employees' work and private life.
