    Experience has clearly demonstrated the need for effective quality assurance programmes throughout the design, procurement and construction phases of the Fast Flux Test Facility (FFTF). Formal quality assurance programmes for FFTF have contributed significantly to the achievement of project objectives thus far in a safe, reliable and predictable manner. Quality assurance programmes empolyed by major FFTF Project participants are based on the requirements of RDT Standard F 2-2, one of the first and most comprehensive standards of its kind. RDT F 2-2 is similar in its basic requirements to ANSI N45.2 and other quality assurance programme standards but differs in its degree of specificity, particularly in its coverage of development activities. RDT F 2-2 is widely applied to a variety of large and small nuclear energy development projects and technology programmes. Full implementation of RDT F 2-2 across the FFTF Project has had its problems and rewards. Problems have been encountered involving misinterpretation or overapplication of requirements. In some instances the problems pointed to the need for more specific requirements, and so the standard was amended to rectify the shortcomings. One valuable lesson learned is that feedback of use experience is essential to the development of a living, viable standard which can be beneficially applied to other projects. Benefits and cost savings have accrued from the preventive aspects of RDT F 2-2. Some examples of experiences and resulting amendments to RDT F 2-2, and their favourable impact on facility costs and schedule, are discussed in this paper. (author)

    Full Text Available The implications for analysis of innovation in construction of theoretical developments in industrial organisation are considered in this research, as an attempt to outline a new approach to construction innovation incorporating the ideas found in knowledge based, technology centred models. The paper firstly summarises characteristics of the construction industry, focusing on their effects on innovation, before surveying some of the ideas about the sources of innovation and the expansion and application of knowledge. Construction can be seen as an industry with limited scope for knowledge externalities, where the procurement methods used by the industry’s clients do not pay for innovation. The following discussion uses recent developments in the research on the economics of innovation and industrial organization theory, such as research intensity and the endogenous sunk costs in competitive, fragmented, low research intensity industries. The effects on R&D of procurement methods and on industry structure are discussed, with a focus on the appropriability of innovations and the role of the client on the Heathrow Terminal 5 project. The paper concludes that the procurement methods used for building and construction projects appears to be a determining factor in the level of innovation in the construction industry

    Environment degradation issue has been a worldwide problem and various efforts have been done to minimise the problem. Construction sectors are pointed as one of the major contributors to its construction activities. Green-oriented procurement [GP] is considered as an environmental strategy to integrate the environmental practices into the construction delivery. Thus, this paper reviews the concept of GP and the practices related to it. The outcome of this research findings provides a basis for understanding the concept of GP and the further development of GP. The listed GP practices identified from this paper can serve as guidelines for industry practitioners to design, implement, and benchmarking the green practices in their procurement delivery.

    Full Text Available Collaborative construction frameworks have been developed in the United Kingdom (UK to create longer term relationships between clients and suppliers in order to improve project outcomes. Research undertaken into highways maintenance set within a major county council has confirmed that such collaborative procurement methods can improve time, cost and quality of construction projects. Building upon this and examining the same single case, this research aims to develop a performance model through identification of performance drivers in the whole project delivery process including pre and post contract phases. A priori performance model based on operational and sociological constructs was proposed and then checked by a pilot study. Factor analysis and central tendency statistics from the questionnaires as well as content analysis from the interview transcripts were conducted. It was confirmed that long term relationships, financial and non-financial incentives and stronger communication are the sociological behaviour factors driving performance. The interviews also established that key performance indicators (KPIs can be used as an operational measure to improve performance. With the posteriori performance model, client project managers can effectively collaboratively manage contractor performance through procurement measures including use of longer term and KPIs for the contract so that the expected project outcomes can be achieved. The findings also make significant contribution to construction framework procurement theory by identifying the interrelated sociological and operational performance drivers. This study is set predominantly in the field of highways civil engineering. It is suggested that building based projects or other projects that share characteristics are grouped together and used for further research of the phenomena discovered.

    Full Text Available Project managers are frequently required to negotiate during the procurement of construction materials and drawing up of contractual agreements. Training in negotiation training requires hands-on experience and interaction with multiple parties. However, in the conventional curriculum on construction management, negotiation is taught merely through lectures and case studies. This study addressed that shortcoming by developing a portfolio negotiation game in which students play different roles and actively make decisions while proceeding through a simulated negotiation process in a competitive context. The proposed game would be the first negotiation game within the domain of the construction industry. During the pilot study, 46 students (with or without industrial working experience played the game; the results showed an increase in learning interest, satisfaction, and effectiveness.

    Full Text Available One of the challenges facing construction procurement performance is the failure to determine the risk related factors limiting its success. These risk factors can cause a significant increase in the procurement cost leading to an increase in the overall project cost. The purpose of this study is to identify and evaluate the risk factors influencing construction procurement performance with a view to achieve the overall project performance. The objectives are to establish a relative significance index score for the most important risk factors limiting the procurement performance of the projects. A self administered questionnaire was employed to the construction industry professionals for responses. A total of 78 questionnaires were distributed to these professionals (architects, quantity surveyors, engineers, and contractors but 62 were returned and analyzed using influential index and later ranked in order of importance. Results of the analysis indicate a disparity in terms of ranking of the factors influencing construction procurement performance. Corruption related risk, conflict of interest, ineffective project technical feasibility, and lack of commitment to transparency were found to be the most significant factors limiting construction procurement performance. Communication barriers and unconfidential tender evaluation process were found to be the low weighted risk factors. The findings can serve as a supportive mechanism for risks management in public construction procurement management. Therefore, construction procurement personnel at all levels of government may find this study relevant, while improving construction procurement performance in the country. It is recommended that construction procurement system should be focused on risks related to corruption, conflict of interest, and effective technical feasibility for improving the overall project performance.

  10. Determinants of procurement strategy for construction works: quantity surveyors’ perspectives

    Directory of Open Access Journals (Sweden)

    Olanrewaju AbdulLateef

    2016-01-01

    Full Text Available The selection of the ‘appropriate’ procurement strategy is a prerequisite to the success or failure of a construction project. This paper investigates the factors determining the selection of appropriate procurement strategy for construction works in Nigeria. Data for the study was collected through an online survey questionnaire. The survey administration involves only quantity surveyors. Quantity surveyors were targeted because they advise clients and other stakeholders on procurement and contractual issues on construction works. A total of 33 usable responses were received and analysed for this study. On the basis of the results, it is concluded that the selection of procurement strategies for construction depend on complex interrelated factors. The study could not detect a particular factor or few factors responsible for a procurement strategy selection. The findings of this study is useful because it argues that the construction sector needs to broaden its considerations on the procurement strategy’s determinants rather than focusing solely on the client’s type and nature of projects as is often cited. Future research could segment these factors in terms of class of construction works or increase the sample size, which might lead to different findings.

    2018-04-01

    Over the last three decades, numerous procurement techniques have been one of the highlights of the Construction Management (CM) for ventures, administration contracting, venture management as well as design and construct. Due to the development and utilization of those techniques, various researchers have explored the criteria for their choice and their execution in terms of time, cost and quality. Nevertheless, there is a lack of giving an account on the relationship between the procurement techniques and the progressed related issues, for example, supply chain, sustainability, innovation and technology development, lean construction, constructability, value management, Building Information Modelling (BIM) as well as e-procurement. Through chosen papers from the reputable CM-related academic journals, the specified scopes of these issues are methodically assessed with the objective to explore the status and trend in procurement related research. The result of this paper contributes theoretically as well as practically to the researchers and industrialist in order to be aware and appreciate the development of procurement techniques.

    2012-12-01

    Full Text Available As demand on building construction projects rises, various procurement methods have been adapted to suit with unique project requirements. However, poor industry performance and rapid developments within it indicate the need for a research on the procurement systems in the industry. In order to explore the development of procurement systems in Malaysia, a discussion on different economic phases which influence the routes of procurement systems and its evolution in Malaysia's construction industry is initiated. Subsequently, based on a questionnaire survey collected from 73 public and 68 private parties, the significant and dominant role of traditional procurement system used by both the public and private sectors in Malaysia can be confirmed. Further, compared to the public sector, the private sector is observed to be more aggressive in adapting alternative systems such as design and build (D&B and Turnkey. Further elaboration on the research findings is covered in the discussion section.

    Full Text Available Purpose of this paper: Procurement systems are vital in ensuring the successful implementation of construction projects precisely in all the phases of any particular project. Therefore, this paper aims to investigate in a systematic manner the factors that influence the selection of a procurement system in the South African construction industry. Research methodology: An extensive theory and literature review of procurement systems was conducted. The literature reviewed included a sample of case studies of procurement systems successfully implemented in completed building and civil engineering projects in South Africa. A questionnaire using a four-round Delphi survey method was used to conduct the empirical study in order to obtain participants' opinions about factors influencing the selection of procurement systems as well as the utility value of various procurement systems on each factor as identified. Finally, data analysis of both qualitative and quantitative techniques was performed using the Statistical Package for Social Sciences (SPSS. Findings: After qualitative analysis, findings of the literature reviewed suggest that factors that influence the selection of procurement systems cut across all the phases of the project as identified in this paper. Therefore, these factors are categorically classified into internal and external factors. Factors from the internal environment were further classified into client characteristics and project characteristics, with client characteristics comprising of variables such as clients' level of knowledge and control, political and social consideration, familiarity of procurement systems, competition, funding arrangement, government public/private sector projects and risk allocation whereas project characteristics comprise of factors (variables such as size and technical complexity of the project, influence of the project life cycle, expedited project delivery, time, quality and price certainty.

    Ajayi, Saheed O; Oyedele, Lukumon O

    2018-05-01

    Albeit the understanding that construction waste is caused by activities ranging from all stages of project delivery process, research efforts have been concentrated on design and construction stages, while the possibility of reducing waste through materials procurement process is widely neglected. This study aims at exploring and confirming strategies for achieving waste-efficient materials procurement in construction activities. The study employs sequential exploratory mixed method approach as its methodological framework, using focus group discussion, statistical analysis and structural equation modelling. The study suggests that for materials procurement to enhance waste minimisation in construction projects, the procurement process would be characterised by four features. These include suppliers' commitment to low waste measures, low waste purchase management, effective materials delivery management and waste-efficient Bill of Quantity, all of which have significant impacts on waste minimisation. This implies that commitment of materials suppliers to such measures as take back scheme and flexibility in supplying small materials quantity, among others, are expected of materials procurement. While low waste purchase management stipulates the need for such measures as reduced packaging and consideration of pre-assembled/pre-cut materials, efficient delivery management entails effective delivery and storage system as well as adequate protection of materials during the delivery process, among others. Waste-efficient specification and bill of quantity, on the other hand, requires accurate materials take-off and ordering of materials based on accurately prepared design documents and bill of quantity. Findings of this study could assist in understanding a set of measures that should be taken during materials procurement process, thereby corroborating waste management practices at other stages of project delivery process.

    Full Text Available The study developed performance indices by the widely used procurement options in Nigeria on selection criteria. The traditional mean and standardized ratio were used to form the utility coefficients. Results revealed that performance by the procurement options depended on the respondents’ categorization and cost categorization of projects. Public clients ranked the lump sum contracts more able to achieve speed for projects up to N100 million (Naira while the private clients believe it is the design-build. As regards quality, public clients rated the Build-Own-Operate-Transfer (BOOT system as most able to achieve the quality criterion whereas private clients rated design-build for projects up to N100 million (Naira. The study then concluded that, in the Nigerian construction industry participants do not agree on the performance of the procurement options on selection criteria.

    OPG is exploring the use of EPC contracts for Nuclear Plant Design Modifications. Although OPG has used EPC outside of the nuclear island, this new initiative will begin to use EPC inside the plant, including upgrades to existing stations and mid-life refurbishment of Darlington. Benchmarking has shown that apart from new build, nuclear utilities rarely use this method inside the plant so OPG is using a step-by-step approach starting with projects with low complexity and low plant impact. The expected benefits are reduced interfaces and a simplified accountability model leading to schedule and cost improvements and lower rework. Design packages that incorporate construction input before issue will be a significant improvement. OPG's early challenges in moving to EPC include clearly defining roles, responsibilities and interfaces between the vendors and OPG, and modifying governance to match the new model. OPG intends to oversee the work while holding the vendor accountable for needs skill development on both sides. Vendors are expected to establish an engaged organization with complete knowledge of plant conditions, processes and streamlined methods to gain operations input. Vendors are also expected to identify and fix any quality issues before the modifications are commissioned and to have an in-house corrective action program to continuously improve. Vendors' early challenges include presenting one face to OPG rather than a collection of joint venture partners. This presentation describes OPG's plans and early feedback on this exciting new initiative.

    Full Text Available The aim of every client at the beginning of any project is to have at the end of the day a quality structure delivered on time and within budget. However, researches have shown that in most cases this aim is not met. The aim of the study that formed the basis for this paper was to identify and assess procurement methods in use in the Nigerian construction industry and identify the factors that affect the choice of the variants under the traditional and the non-conventional procurement methods. Data were collected using well-structured questionnaires administered to professionals in Lagos metropolis. Data collected were analyzed using descriptive and inferential statistics. The study reveals that the variants of traditional method of contract procurement are the most adopted in project execution in Nigeria. In making choice of procurement method, the study reveals that project completion at estimated time ranks as the highest factor considered for traditional method, while quality assurance ranks highest with non-conventional method.

    There are many variables that public clients need to consider in their bidding procedure to enhance efficiency in their procurement for construction services. This paper focusses on the competitive bidding process for public sector procurement of construction services in Singapore. A distinctive feature of the Singapore government competitive bidding process is that full bidding feedback information is released to all competing bidders (and public). The specific objectives are: (i) to examine the degree of competition in the construction markets; and (ii) to examine the bidding performance of competing bidders. Based on a collection of bidding data for a 15-month period, the results show the market environment of the Singapore public sector construction contracting is highly competitive with long bidder lists. In selection of contractors, only 50% of the contracts were awarded to lowest bidders. The results also show that the competing contractors can be broadly classified into three groups based on their bidding performance in terms of number of bidding attempts, bidding success rate and bidding competitiveness. These results provide a useful insight into the bidding competition in the Singapore public sector construction contracting, especially to new market entrants and foreign contractors who want to bid for jobs in Singapore.

    1986-08-01

    This paper describes the construction and testing of the Mirror Fusion Test Facility superconducting magnet set. Construction of the first Yin Yang magnet was started in 1978. And although this particular magnet was later modified, the final construction of these magnets was not completed until 1985. When completed these 42 magnets weighed over 1200 tonnes and had a maximum stored energy of approximately 1200 MJ at full field. Together with power supplies, controls and liquid nitrogen radiation shields the cost of the fabrication of this system was over $100M. General Dynamics/Convair Division was responsible for the system design and the fabrication of 20 of the magnets. This contract was the largest single procurement action at the Lawrence Livermore National Laboratory. During the PACE acceptance tests, the 26 major magnets were operated at full field for more than 24 hours while other MFTF subsystems were tested.

    2016-01-01

    Full Text Available In the respect of value, public procurement in the construction industry belongs to one of the largest ones in the domestic market. Therefore, green procurement for construction works should become the center of attention of public authorities in a broad sense, due to its scale and importance for the sustainable development. The authorities and contracting entities who spend public money should have the opportunity to apply such legal articles and instruments that allow them to both optimize public expenditures and consider the environmental factor, such as decreasing carbon emission. To make the idea of sustainable development a reality as European Union’s the most vital aim, EU law is implemented in Poland. Local authorities’ duty is to appropriately shape their policies and use the vital instrument of sustainable development, namely green public procurement. This paper presents a comparative analysis of legal regulations to illustrate the actual Polish and EU laws concerning the construction industry. Even though the generally applicable law allows to implement the idea of sustainable development efficiently, local self-government units in their regional policies do not report any need for specific solutions, or they do so only occasionally.

This paper propose a comprehensive study on the supplier selection metrics for infrastructure building, weight the importance of each metrics assigned and to find the relationship between the metrics among initiators, decision makers, buyers and users. With the metrics hierarchy of criteria importance, a supplier selection process can be defined, repeated and audited with lesser complications or difficulties. This will help the field of procurement to improve as this research is able to develop and redefine policies and procedures that have been set in supplier selection. Developing this systematic process will enable optimization of supplier selection and thus increasing the value for every stakeholders as the process of selection is greatly simplified. With a new redefined policy and procedure, it does not only increase the company’s effectiveness and profit, but also make it available for the company to reach greater heights in the advancement of procurement in Malaysia.

  5. The application of an integrated approach to design, procurement and construction in reducing overall nuclear power plant costs. Annex 19

    2002-01-01

    As part of its on-going efforts to reduce the cost of CANDU nuclear power plants, AECL has embarked on an integrated approach to design, procurement and construction activities associated with new CANDU 6 and CANDU 9 projects. The approach is predicated on the fact there is a vast quantity of information that needs to be managed and controlled over the life of a nuclear power plant project. Therefore, ensuring the completeness and correctness of all the information needed by all project participants, facilitating sharing of this information amongst the project's participants, and automating the various deliverable production processes offers significant potential not only for overall project cost (and schedule) savings but also for reducing operations and maintenance costs once the plant enters service. Facilitating and indeed of key importance to this approach is the use of a suite of integrated information technology-based engineering, procurement and project control tools used throughout the design, engineering, procurement and construction phases of the project. A unique and important feature of these tools is their high degree of integration both from a work process and a data perspective. Use of these tools is well underway on AECL's Qinshan Project which is realizing significant benefits in cost and schedule. This paper will describe the approach AECL is taking, along with the tools it has both put in place, and those additional items planned for the future along with the cost, schedule and quality benefits that arise from their use. Progress to date on the Qinshan project also will be discussed as well as the expected application to the plant once it has gone into service will also be discussed. (author)

    Our organ procurement organization (OPO) evaluated the clinical and financial efficacy of point-of-care testing (POCT) in management of our deceased organ donors. Before we implemented point-of care testing with the i-STAT into routine clinical donor management, we compared the i-STAT result with the result from the respective donor hospital lab (DHL) for certain analytes on 15 consecutive donors in our OPO from 26 March to 14 May 2001. The financial impact was studied by reviewing 77 donors from July 2001 to March 2002. There was a strong correlation for each analyte between the POC and DHL test results with r-values as follows: pH 0.86; PCO2 = 0.96; PO2 = 0.98; sodium = 0.98; potassium = 0.95; chloride = 0.94; BUN = 0.98; glucose = 0.92; haematocrit = 0.87 and creatinine = 0.95. Since our OPO coordinators began using i-STAT in their routine clinical management of organ donors, they can now more quickly maximize oxygenation and fluid management of the donor and make extra-renal placement calls sooner. Finally, since we are no longer being billed for the testing performed on the i-STAT, average financial savings to our OPO are US dollars 733 per case. Point-of-care testing in management of our OPO donors provides a result that is equivalent to that of the donor hospital lab, has quicker turn-around time than the donor hospital laboratory, allowing more immediate clinical management decisions to be made so that extra-renal offers may begin sooner.

    This report documents a test transfer of three Air Force technical procurement bid sets to one large and twelve small businesses, using the Department of Defense (DoD) Continuous Acquisition and Life-cycle Support (CALS) and ANSI ASC X12 Electronic Data Interchange (EDI) standards. The main goal of the test was to evaluate the effectiveness of using CALS technical data within the context of the DoD`s EDI-based standard approach to electronic commerce in procurement, with particular emphasis on receipt and use of the data by small contractors. Air Force procurement data was provided by the Sacramento Air Logistics Center at McClellan Air Force Base; the manufacturing participants were selected from among McClellan`s ``Blue Ribbon`` contractors, located throughout the US. The test was sponsored by the Air Force CALS Test Network, headquartered at Wright-Patterson Air Force Base. The test successfully demonstrated the technical feasibility of including CALS MIL-R-28002 (Raster) engineering data in an EDI Specification/Technical Information transaction set (ANSI ASC X12 841) when issuing electronic requests for quotation to small businesses. In many cases, the data was complete enough for the contractor participant to feel comfortable generating a quote. Lessons learned from the test are being fed back to the CALS and EDI standards organizations, and to future implementors of CALS-EDI based acquisition or contracting systems, which require the transfer of technical information, such as engineering data, manufacturing process data, quality test data, and other product or process data, in the form of a CALS or other digital datafile.

    The Voice Activated Information System (VAIS), developed by USACERL, allows inspectors to verbally log on-site inspection reports on a hand held tape recorder. The tape is later processed by the VAIS, which enters the information into the system's database and produces a written report. The Voice Operated Information System (VOIS), developed by USACERL and Automated Sciences Group, through a ESACERL cooperative research and development agreement (CRDA), is an improved voice recognition system based on the concepts and function of the VAIS. To determine the applicability of the VOIS to Corps of Engineers construction projects, Technology Transfer Test Bad (T3B) funds were provided to the Corps of Engineers National Security Agency (NSA) Area Office (Fort Meade) to procure and implement the VOIS, and to train personnel in its use. This report summarizes the NSA application of the VOIS to quality assurance inspection of radio frequency shielding and to progress payment logs, and concludes that the VOIS is an easily implemented system that can offer improvements when applied to repetitive inspection procedures. Use of VOIS can save time during inspection, improve documentation storage, and provide flexible retrieval of stored information.

    Full Text Available This paper examines government targeted procurement (TP strategies in South Africa and whether these strategies have an influence on the growth performance of Small and medium-sized contractors (SMCs in the construction industry. The rationale for this study stems from reports that while TP has been widely used as an instrument to improve the position of SMCs in the South African construction industry, three out of five SMCs do not become established firms. In addition, the nature of the influence of TP strategies on the growth performance of SMCs is not known. Following a review of existing literature, the study mainly adopted a quantitative research approach. Questionnaire surveys were administered to Construction Industry Development Board (cidb Grades 3 to 6 contractors that have executed TP projects within the last 5 years. The collected data was subjected to descriptive and inferential statistical analyses – Spearman’s rank order correlation was used as an index of association between the study variables. The study found that tendering equity is the most frequently used TP strategy, closely followed by preferencing and mandatory subcontracting. The study also found that positive significant associations exists among preferencing and turnover; third-party management and company assets; tendering equity, turnover and number of employees; as well as accelerated rotations, turnover and number of employees. The study concluded that government intervention through targeted procurement has the potential to achieve its intended results of improving the position of historically disadvantaged SMCs in the construction industry in South Africa if selected and implemented appropriately.

  6. The design, construction and testing of packaging

    International Nuclear Information System (INIS)

    1976-01-01

    Essentially uniform regulations, based on the IAEA Regulations for the Safe Transport of Radioactive Materials, have been adopted on a world-wide basis with the aim of ensuring safety in the transport of radioactive and fissile substances by road, rail, sea and air. The application of these regulations over a period of almost 20 years has resulted in practically complete safety in the sense that there has been no evidence of death or injury that could be attributed to the special properties of the material even when consignments were involved in serious accidents. In the regulations, reliance is placed, to the greatest extent possible, on the packaging to provide adequate shielding and containment of the contents under both normal transport and accident conditions. The Agency organized an international seminar in 1971 to consider the performance tests that have to be applied to packaging to demonstrate compliance with the regulatory requirements. The general conclusion was that the testing programme specified in the regulations was adequate for the near future, but that further consideration should be given to assessing the risks presented by the increasing volume of transport. The second international seminar, which is the subject of this report, dealt with all aspects of the design, construction and testing of packaging for the transport both of relatively small quantities of radioactive substances, which are being used to an ever increasing extent for medical and research purposes, and of the much larger quantities arising in various stages of the nuclear fuel cycle. The programme covered the general requirements for packaging; risk assessment for the transport of various radioactive and fissile substances, including plutonium; specific features of the design and construction of packaging; quality assurance; damage simulation tests, including calculational methods and scale-model testing; tests for the retention of shielding and containment after damage; and the

    Full Text Available Steel is a kind of ferromagnetic material, which is extensively applied in such fields as buildings, bridges, railways, machines and lifeline engineering etc. Those engineering structures built of constructional steel will unavoidably experience some damages during their service lifetime, thus which will influence the distribution regularity of internal forces in structures, result in over-stresses, cause the local failure of structures, and even lead to collapse of the whole structure. Therefore, it is a pressing topic to study how to directly evaluate the real-time stressed states of structural members, damages and steel characteristics in present structural health monitoring and diagnosing fields. And the achievements of this research will be of theoretical significance and of application value of engineering. This paper summarizes varieties of new magnetic nondestructive testing techniques used in constructional steel, respectively investigates the testing principles, characteristics and application for the magnetic Barkhausen noise technique, magnetic acoustic emission technique, magnetic flux leakage technique, magnetic memory technique and magnetic absorption technique, and points out the problems present in the application of these new techniques to actual testing and the further research objective.

    Organ donation remains a major public health challenge with over 114 000 people on the waitlist in the United States. Among other factors, extant research highlights the need to improve the identification and timely referral of potential donors by hospital health-care providers (HCPs) to organ procurement organizations (OPOs). We implemented a national test of the Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) to identify assets and barriers to the organ donation and patient referral processes; assess hospital–OPO relationships and offer tailored recommendations for improving these processes. Having partnered with seven OPOs, data were collected at 70 hospitals with high donor potential in the form of direct observations and interviews with 2358 HCPs. We found that donation attitudes and knowledge among HCPs were high, but use of standard referral criteria was lacking. Significant differences were found in the donation-related attitudes, knowledge and behaviors of physicians and emergency department staff as compared to other staff in intensive care units with high organ donor potential. Also, while OPO staff were generally viewed positively, they were often perceived as outsiders rather than members of healthcare teams. Recommendations for improving the referral and donation processes are discussed. PMID:22900761

  10. JOYO construction and preoperational test experience

    International Nuclear Information System (INIS)

    1976-03-01

    The construction and installation of Joyo, the first experimental fast reactor in Japan, have been completed. The application for the license for Joyo was made with the output of 50 MWt, and the power raising to 100 MWt target is left for future. Joyo is a sodium-cooled fast breeder reactor with mixed oxide fuel. The research and development for and the construction of Joyo are described. The initial stage of the preoperational test has been finished, and the further test stage is in progress. Sodium-cooled fast reactors are operated at higher temperature and lower pressure as compared with light water reactors, therefore the thermal stress is high, while the mechanical stress is low. The materials used for the sodium components are apt to creep, while the mechanical properties are impaired by the mass transfer in the hot sodium circuits. The guide lines for the structural design of Joyo were established on the basis of ASME Boiler and Pressure Vessel Code. The basic philosophy and the method of the aseismatic design for Joyo are almost same as those for large commercial reactor plants. The thermal shock due to air blast coolers cannot be avoided in LMFBRs, but care should be taken in the design to mitigate the shock. It is desirable to establish more detailed standards on inspection and examination to cope with complex LMFBRs. (Kako, I.)

    2016-07-01

    Full Text Available Suitable and sustainable buildings have increased demands for design and for the transfer of design requirements to realization. That causes an increase of risk connected with the differences between planned and real parameters of the buildings. This article will outline the main theme comparison between DBB and DB projects concerning contractor’s risk management level. This comparative analysis explains, using the RIPRAN method, the hidden risks in each type of delivery method. The comparison identifies numerous contractual topics and risks included in both and gives deeper insight into risk management, both for the contracting party and also for public procurement. Applying risk analysis strategies and tools to the process will help decision-makers evaluate and select the suitable delivery method consistently and defensibly. This paper gives generic risk factors related to both project types. The results indicate risk factors with influence on the price, probability of occurrence and unfavourable impact on the project and help allocate risk level more properly in accordance with its high, middle or low probable impact. Public investment is a significant part of the public budget, the application of design-build can help with the reduction of corruption, and the public sector can benefit from the usage of DB projects to help eliminate the mistakes made by contracting authorities.

    2014-08-01

    NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner's representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

    When creating a private market to provide a public good, government agencies can influence the market's competitive characteristics. Markets have predictable, but often counterintuitive, behaviors. To succeed in applying available controls, and thereby reduce future costs, agencies must understand the behavior of the market. A model has been constructed to examine some issues in establishing competition for a structure in which there are economies of scale and government is obligated to purchase a fixed total quantity of a good. This model is used to demonstrate a way to estimate the cost savings from several alternative plans for a buyer exploring competitive procurement. The results are not and cannot be accurate for budgeting purposes; rather, they indicate the approximate magnitude of changes in cost that would be associated with changes in the market structure within which procurement occurs

    The test facility for performance verification of the control element drive mechanism (CEDM) of next generation power plant was installed at the site of KAERI. The CEDM was featured a mechanism consisting of complicated mechanical parts and electromagnetic control system. Thus, a new CEDM design should go through performance verification tests prior to it's application in a reactor. The test facility can simulate the reactor operating conditions such as temperature, pressure and water quality and is equipped with a test chamber to accomodate a CEDM as installed in the power plant. This test facility can be used for the following tests; endurance test, coil cooling test, power measurement and reactivity rod drop test. The commissioning tests for the test facility were performed up to the CEDM test conditions of 320 C and 150 bar, and required water chemistry was obtained by operating the on-line water treatment system.

    Nonmagnetic proton detectors will be used in future at the ELAN experiment. For this purpose a prototype of a proton telescope has being designed. The detector consists of three scintillation counters which are used as dE/dx counter, energy (stopping) counter and veto counter. This telescope was calibrated by using elastic electron proton scattering and tested with quasielastic electrodisintegration of the deuteron. These are no principal problems to identify the protons. In the electrodisintegration of the deuteron a missing mass resolution of ± 5.1 MeV was achieved. It has been shown, that such detectors are well suited for proton detection. (orig.) [de

    The Nuclear Anxiety Scale was administered to 263 undergraduate and graduate studies (on eight occasions in December, 1985 and January, 1986). (1) The obtained alpha coefficient was .91. This was significant at the .01 level, and demonstrated that the scale was internally homogeneous and consistent. (2) Item discrimination indices (point biserial correlation coefficients) computered for the thirty (30) items yielded a range of .25 to .64. All coefficients were significant at the .01 level, and all 30 items were retained as demonstrating significant discriminability. (3) The correlation between two administrations of the scale (with a 48-hour interval) was .83. This was significant at the .01 level, and demonstrated test-retest reliability and stability over time. (4) The point-biserial correlation coefficient between scores on the Nuclear Anxiety Scale, and the students' self-report of nuclear anxiety as being either a high or low ranked stressor, was .59. This was significant at the .01 level, and demonstrated concurrent validity. (5) The correlation coefficient between scores on the Nuclear Anxiety Scale and the Spielberger State-Trait Anxiety Inventory, A-Trait, (1970), was .41. This was significant at the .01 level, and demonstrated convergent validity. (6) The correlation coefficient between positively stated and negatively stated items (with scoring reversed) was .76. This was significant at the .01 level, and demonstrated freedom from response set bias

    Malaria rapid diagnostic tests (RDTs) play a critical role in malaria case management, and assurance of quality is a key factor to promote good adherence to test results. Since 2007, the World Health Organization (WHO) and the Foundation for Innovative New Diagnostics (FIND) have coordinated a Malaria RDT Evaluation Programme, comprising a pre-purchase performance evaluation (product testing, PT) and a pre-distribution quality control of lots (lot testing, LT), the former being the basis of WHO recommendations for RDT procurement. Comprehensive information on malaria RDTs sold worldwide based on manufacturers' data and linked to independent performance data is currently not available, and detailed knowledge of procurement practices remains limited. The use of the PT/LT Programme results as well as procurement and lot verification practices were assessed through a large-scale survey, gathering product-specific RDT sales and procurement data (2011-14 period) from a total of 32 manufacturers, 12 procurers and 68 National Malaria Control Programmes (NMCPs). Manufacturers' reports showed that RDT sales had more than doubled over the four years, and confirmed a trend towards increased compliance with the WHO procurement criteria (from 83% in 2011 to 93% in 2014). Country-level reports indicated that 74% of NMCPs procured only 'WHO-compliant' RDT products, although procurers' transactions datasets revealed a surprisingly frequent overlap of different products and even product types (e.g., Plasmodium falciparum-only and Plasmodium-pan) in the same year and country (60 and 46% of countries, respectively). Importantly, the proportion of 'non-complying' (i.e., PT low scored or not evaluated) products was found to be higher in the private health care sector than in the public sector (32% vs 5%), and increasing over time (from 22% of private sector sales in 2011 to 39% in 2014). An estimated 70% of the RDT market was covered by the LT programme. The opinion about the PT

    2002-01-01

    Drug testing in the workplace has gone from virtual nonexistence to widespread employer acceptance during the past two decades. This growth is particularly significant for the construction industry. High rates of alcohol and other drug use, coupled with the high-risk, safety-sensitive nature of the industry, have prompted the development of a variety of drug surveillance and prevention strategies. Despite this growing vigilance, no scholarly works have examined the impact of drug-related policies in the construction industry. To address this limitation, we investigate the efficacy of workplace drug-testing programs in reducing injury incident rates and workers' compensation experience-rating modification factors (MODs) within the construction industry. Analyses indicate that companies with drug-testing programs experienced a 51 percent reduction in incident rates within two years of implementation. Moreover, companies that drug test their employees experienced a significant reduction in their MODs. Policy implications are discussed in light of the current findings.

    Plant constitutional parts as targets of both of a primary pressure test and a secondary pressure test are disposed in communication with a reactor pressure vessel, and a pressure of the primary pressure test is applied to the targets of both tests, so that the primary pressure test and the second pressure test are conducted together. Since the number of pressure tests can be reduced to promote construction, and the number of workers can also be reduced. A pressure exceeding the maximum pressure upon use is applied to the pressure vessel after disposing the incore structures, to continuously conduct the primary pressure test and the secondary pressure test joined together and an incore flowing test while closing the upper lid of the pressure vessel as it is in the construction field. The number of opening/closing of the upper lid upon conducting every test can be reduced, and since the pressure resistance test is conducted after arranging circumference conditions for the incore flowing test, the tests can be conducted collectively also in view of time.

    EIA plays an important role in enhancing the environmental performance of the construction sector. In recent years, the construction sector has been developing green procurement practices. Green procurement is a process that involves the incorporation of environmental requirements during the procurement of services and products. However, discussion on green procurement is rarely seen during the EIA phase. This paper addresses possible opportunities for improving the coordination between EIA and green procurement within the construction sector. The linking of EIA and green procurement has been postulated in the paper as an aid to strengthen the coordination between project planning and implementation. The paper is based on a literature review and is an outcome of an on-going research project concerning EIA and green procurement. This study indicated that it would be appropriate to introduce green procurement during the pre-decision phase of an EIA. In the present study, the opportunities for integrating green procurement at the stage of EIA are associated with the integration of project planning and EIA. Future research should investigate the mechanism through which the link can be established. - Highlights: ► This paper identifies opportunities to link EIA and green procurement. ► Pre-decision phase of EIA could be appropriate for planning green procurement. ► Future research should investigate the mechanism for establishing the link.

    EIA plays an important role in enhancing the environmental performance of the construction sector. In recent years, the construction sector has been developing green procurement practices. Green procurement is a process that involves the incorporation of environmental requirements during the procurement of services and products. However, discussion on green procurement is rarely seen during the EIA phase. This paper addresses possible opportunities for improving the coordination between EIA and green procurement within the construction sector. The linking of EIA and green procurement has been postulated in the paper as an aid to strengthen the coordination between project planning and implementation. The paper is based on a literature review and is an outcome of an on-going research project concerning EIA and green procurement. This study indicated that it would be appropriate to introduce green procurement during the pre-decision phase of an EIA. In the present study, the opportunities for integrating green procurement at the stage of EIA are associated with the integration of project planning and EIA. Future research should investigate the mechanism through which the link can be established. - Highlights: Black-Right-Pointing-Pointer This paper identifies opportunities to link EIA and green procurement. Black-Right-Pointing-Pointer Pre-decision phase of EIA could be appropriate for planning green procurement. Black-Right-Pointing-Pointer Future research should investigate the mechanism for establishing the link.

    The solid waste form test facility (SWFTF) to test and/or evaluate the characteristics of waste forms, such as homogeniety, mechanical properties, thermal properties, waste resistance and leachability, have been constructed, and some equipments for testing actual waste forms has been purchased; radiocative monitoring system, glove box for the manipulator repair room, and uninteruppted power supply system, et al. Classifications of radioactive wastes, basic requirements and criteria to be considered during waste management were also reviewed. Some of the described items above have been standardized for the purpose of indigenigation. Therefore, safety assurance of waste forms, as well as increase in the range of participating of domestic companies in construction of further nuclear facilities could be obtained as results through constructing this facility. In the furture this facility is going to be utilized not only for the inspection of waste forms but also for the periodic decontamination for extending the life time of some expensive radiological equipments using remote handling techniques.

    Hydropower is one of the clean, renewable, flexible and efficient energy resources. Most of the developing countries invest on this cost-effective energy source. Hydroturbines for hydroelectric power plants are tailor-made. Each turbine is designed and constructed according to the properties, namely the head and flow rate values of the specific water source. Therefore, a center (ETU Hydro-Center for Hydro Energy Research) for the design, manufacturing and performance tests of hydraulic turbines is established at TOBB University of Economics and Technology to promote research in this area. CFD aided hydraulic and structural design, geometry optimization, manufacturing and performance tests of hydraulic turbines are the areas of expertise of this center. In this paper, technical details of the design and construction of this one of a kind test facility in Turkey, is explained. All the necessary standards of IEC (International Electrotechnical Commission) are met since the test facility will act as a certificated test center for hydraulic turbines.

    Full Text Available Geobag retaining wall using construction waste is a new flexible supporting structure, and the usage of construction waste to fill geobags can facilitate the construction recycling. In this paper, model tests were performed on geobag retaining wall using construction waste. The investigation was concentrated on the slope top settlement, the distribution characteristics of the earth pressures on retaining walls and horizontal wall displacements, and slope failure modes. The results indicated that the ultimate loads that the slope tops with retaining walls could bear were 87.5%~125% higher than that of the slope top without retaining walls. The ultimate loading of strengthened slopes with different slope ratios from 1 : 0.75 to 1 : 0.25 could be reduced by 11.8% to 29.4%. The horizontal displacements of the retaining walls constructed from geobags were distributed in a drum shape, with the greatest horizontal displacements occurring about 1/3~1/2 of the wall height away from the bottom of the wall. As the slope ratio increased, the failure of the slope soil supported by geobag retaining wall using construction waste changed from sliding to sliding-toppling (dominated by sliding and then to toppling-sliding (dominated by toppling. The range of 1/3~1/2 of wall height is the weak part of the retaining walls, which should be strengthened with certain measures during the process of design and construction.

  14. The influence of technical testing methods on perceptions of constructions

    International Nuclear Information System (INIS)

    Oestberg, Gustaf

    2002-01-01

    In principle, methods of testing the reliability and safety of constructions are designed with the aim of representing critical conditions for their use. Because of variations within technical systems, including the one for which a certain test was once developed, the validity of the method also varies. The adoption of a standardized test for different applications had to be based on the assumption that the test deals adequately with a real situation. As a consequence of this acceptance of a trustworthy relationship between test and reality, an imprint of the former on the latter occurs. This effect may even cause the perception of a reality to be defined by the corresponding test. Examples of such an influence may be found in the field of materials testing. Related phenomena can be dealt with by reference to current concepts of cognitive science and psychology of the perception of images

    The 2012 IECC has an airtightness requirement of 3 air changes per hour at 50 Pascals test pressure for both single-family and multifamily construction in Climate Zones 3-8. Other programs (LEED, ASHRAE 189, ASHRAE 62.2) have similar or tighter compartmentalization requirements, driving the need for easier and more effective methods of compartmentalization in multifamily buildings. Builders and practitioners have found that fire-resistance rated wall assemblies are a major source of difficulty in air sealing/compartmentalization, particularly in townhouse construction. This problem is exacerbated when garages are “tucked in” to the units and living space is located over the garages. In this project, Building Science Corporation examined the taping of exterior sheathing details to improve air sealing results in townhouse and multifamily construction, when coupled with a better understanding of air leakage pathways. Current approaches are cumbersome, expensive, time consuming, and ineffective; these details were proposed as a more effective and efficient method. The effectiveness of these air sealing methods was tested with blower door testing, including “nulled” or “guarded” testing (adjacent units run at equal test pressure to null out inter-unit air leakage, or “pressure neutralization”). Pressure diagnostics were used to evaluate unit-to-unit connections and series leakage pathways (i.e., air leakage from exterior, into the fire-resistance rated wall assembly, and to the interior).

    The two-phase critical test loop facility has been constructed in the KAERI engineering laboratory for the simulation of small break loss of coolant accident entrained with non-condensible gas of SMART. The test facility can operate at 12 MPa of pressure and 0 to 60 C of sub-cooling with 0.5 kg/s of non- condensible gas injection into break flow, and simulate up to 20 mm of pipe break. Main components of the test facility were arranged such that the pressure vessel containing coolant, a test section simulating break and a suppression tank inter-connected with pipings were installed vertically. As quick opening valve opens, high pressure/temperature coolant flows through the test section forming critical two-phase flow into the suppression tank. The pressure vessel was connected to two high pressure N2 gas tanks through a control valve to control pressure in the pressure vessel. Another N2 gas tank was also connected to the test section for the non-condensible gas injection. The test facility operation was performed on computers supported with PLC systems installed in the control room, and test data such as temperature, break flow rate, pressure drop across test section, gas injection flow rate were all together gathered in the data acquisition system for further data analysis. This test facility was classified as a safety related high pressure gas facility in law. Thus the loop design documentation was reviewed, and inspected during construction of the test loop by the regulatory body. And the regulatory body issued permission for the operation of the test facility

    The effect of non-commutativity on electromagnetic waves violates Lorentz invariance: in the presence of a background magnetic induction field b, the velocity for propagation transverse to b differs from c, while propagation along b is unchanged. In principle, this allows a test by the Michelson-Morley interference method. We also study non-commutativity in another context, by constructing the theory describing a charged fluid in a strong magnetic field, which forces the fluid particles into ...

    Full Text Available Measurement of students’ knowledge is an essential part of the educational process. Teachers on universities often use computer-based tests to testing a large number of students in a short time. The question is, what kind of information these tests provide, and if it is possible to classify students on this basis. Praxis shows that the scalar test results in the form of simple numbers cannot be plainly interpreted as the level of knowledge; moreover it is not easy to build such tests, which detect the necessary information. In the first part of the article we present the results of pedagogical experiment focused on the difference between information obtained through the computer-based test and a teacher’s interview with the same students. Possible starting point to improve information from computer-based tests in non-scalar form is a construction of an adaptive test, adapting test items to identify knowledge similar to a conversation with a teacher. As a tool for the design of the adaptive tests we use so called study maps, which are described in the second part of the article.

    1996-01-01

    In March, 1991, the Japan Atomic Energy Research Institute (JAERI) started to constructed the High Temperature engineering Test Reactor(HTTR) which is a 30-MW(thermal) helium gas-cooled reactor with a core composed of prismatic graphite blocks piled on the core support graphite structures. Two types of graphite materials are used in the HTTR. One is the garde IG-110, isotropic fine grain graphite, another is the grade PGX, medium-to-fine grained molded graphite. These materials were selected on the basis of the appropriate properties required by the HTTR reactor design. Industry-wide standards for an acceptance test of graphite materials used as main components of a nuclear reactor had not been established. The acceptance standard for graphite components of the HTTR, therefore, was drafted by JAERI and reviewed by specialists outside JAERI. The acceptance standard consists of the material testing, non-destructive examination such as the ultrasonic and eddy current testings, dimensional and visual inspections and assembly test. Ultrasonic and eddy current testings are applied to graphite logs to detect an internal flaw and to graphite components to detect a surface flaw, respectively. The assembly test is performed at the works, prior to their installation in the reactor pressure vessel, to examine fabricating precision of each component and alignment of piled-up structures. The graphite components of the HTTR had been tested on the basis of the acceptance standard. It was confirmed that the graphite manufacturing process was well controlled and high quality graphite components were provided to the HTTR. All graphite components except for the fuel graphite blocks are to be installed in the reactor pressure vessel of the HTTR in September 1995. The paper describes the construction status of the HTTR focusing on the graphite components. The acceptance test results are also presented in this paper. (author). Figs

    The present thesis presents the first fully applicable silicon detectors which work as drift chambers. Four different types of detectors were constructed. By a suitable geometry and electronic lay-out one- and two-dimensional position measurements were made possible. Chapter 2 describes function and construction of the detectors, chapter 3 their fabrication process. In chapter 4 construction and results of the test of a silicon drift chamber under laboratory conditions are described. By variation of the applied voltages the optimal operational conditions could be determined and material properties of the silicon, as for instance the electron mobility measured. A position resolution better than 5 μm at a drift length up to 4 mm was reached. Chapter 5 presents the results of the test of a silicon drift chamber under real experimental conditions in a particle beam of the super proton synchroton (SPS) of CERN. The best position resolution measured there is 10 μm. Chapter 6 summarizes the obtained results and discusses finally application possibilities and improvement proposals for silicon drift chambers.

    Transplantation is an accepted therapeutic option to save or improve the quality of life when organ failure occurs or tissue replacements are needed. However, the lack of organs is the major limitation. The deceased organ procurement organization and professionals provide the solution to this international problem. In this review, we identify the elements involved in the organ procurement management process to analyze the possibility of implementation of deceased organ procurement for a transplantation program. While the donation rates are subject to several negative factors including religious, economic, cultural, and legal issues, the existence of well-trained professionals may considerably increase them. Professional training in organ donation along with the establishment of a solid organizational system has been identified as the crucial factor in developing efficient organ donation and transplantation programs.

    1976-07-01

    Essentially uniform regulations, based on the IAEA Regulations for the Safe Transport of Radioactive Materials, have been adopted on a world-wide basis with the aim of ensuring safety in the transport of radioactive and fissile substances by road, rail, sea and air. The application of these regulations over a period of almost 20 years has resulted in practically complete safety in the sense that there has been no evidence of death or injury that could be attributed to the special properties of the material even when consignments were involved in serious accidents. In the regulations, reliance is placed, to the greatest extent possible, on the packaging to provide adequate shielding and containment of the contents under both normal transport and accident conditions. The Agency organized an international seminar in 1971 to consider the performance tests that have to be applied to packaging to demonstrate compliance with the regulatory requirements. The general conclusion was that the testing programme specified in the regulations was adequate for the near future, but that further consideration should be given to assessing the risks presented by the increasing volume of transport. The second international seminar, which is the subject of this report, dealt with all aspects of the design, construction and testing of packaging for the transport both of relatively small quantities of radioactive substances, which are being used to an ever increasing extent for medical and research purposes, and of the much larger quantities arising in various stages of the nuclear fuel cycle. The programme covered the general requirements for packaging; risk assessment for the transport of various radioactive and fissile substances, including plutonium; specific features of the design and construction of packaging; quality assurance; damage simulation tests, including calculational methods and scale-model testing; tests for the retention of shielding and containment after damage; and the

    The 2012 International Energy Conservation Code (IECC) has an airtightness requirement of 3 air changes per hour at 50 Pascals test pressure (3 ACH50) for single-family and multifamily construction (in climate zones 3–8). The Leadership in Energy & Environmental Design certification program and ASHRAE Standard 189 have comparable compartmentalization requirements. ASHRAE Standard 62.2 will soon be responsible for all multifamily ventilation requirements (low rise and high rise); it has an exceptionally stringent compartmentalization requirement. These code and program requirements are driving the need for easier and more effective methods of compartmentalization in multifamily buildings.

    2014-05-01

    Full Text Available This paper builds on previous research by the authors which determined the global state-of-the-art of constructing tall buildings by surveying the most active specialist tall building professionals around the globe. That research identified the effect of wind on tower cranes as a highly ranked, common critical issue in tall building construction. The research reported here presents a design for a “Lifting Wing,” a uniquely designed shroud which potentially allows the lifting of building materials by a tower crane in higher and more unstable wind conditions, thereby reducing delay on the programmed critical path of a tall building. Wind tunnel tests were undertaken to compare the aerodynamic performance of a scale model of a typical “brick-shaped” construction load (replicating a load profile most commonly lifted via a tower crane against the aerodynamic performance of the scale model of the Lifting Wing in a range of wind conditions. The data indicate that the Lifting Wing improves the aerodynamic performance by a factor of up to 50%.

    We demonstrate basic operations of a two-component superconducting gravity gradiometer (SGG) that is constructed with a pair of magnetically levitated test masses coupled to superconducting quantum-interference devices. A design that gives a potential sensitivity of 1.4 ×10-4 E Hz-1 /2 (1 E ≡10-9 s-2 ) in the frequency band of 1 to 50 mHz and better than 2 ×10-5 E Hz-1 /2 between 0.1 and 1 mHz for a compact tensor SGG that fits within a 22-cm-diameter sphere. The SGG has the capability of rejecting the platform acceleration and jitter in all 6 degrees of freedom to one part in 109 . Such an instrument has applications in precision tests of fundamental laws of physics, earthquake early warning, and gravity mapping of Earth and the planets.

    Full Text Available Top and bottom liners are one of the key construction elements in every landfill. They are usually made as compacted clay liners (CCLs composed of several layers of compacted clay with strictly defined properties or by the use of alternative materials such as: GCL – geosynthetic clay liner, BES – bentonite enhanced soils or bentonite/polymer mixtures. Following the state of the art experiences in the world, GCLs are used in Croatian landfills for several years, as well. Depending upon the location and the obeying function, GCLs have to fulfill certain conditions. A legislated compatibility criterion has to be proven by various laboratory tests. In the paper are presented the results of direct shear and chemical compatibility tests of GCLs as well as the results of permeability measurement of kaolin clay (the paper is published in Croatian .

    Some years back, after the discovery of Petroleum, Kerosene as one of the fraction of the distillation of Petroleum came into use as cooking fuel and a reduction in pressure was seen on wood and vegetation. Along this line, by the improvement of sciences and technology gas cooker and electric cooker were developed; but epileptic supply of electricity, gas and government policy on deforestation showed that continuous dependence on wood, electricity, gas and kerosene as the only sources of cooking fuel is not going to solve Nigeria domestic cooking problem. To solve this, coal as a source of heat energy could be used as a cooking fuel. However, this paper reports the design of coal stove, construction, assembly and test. The test result showed that using coal (anthracite) as the fuel on a pot of 200g containing 800g of water at room temperature could boil the water in 20 minutes

    Full Text Available The assessment of listening abilities is one of the least understood, least developed and, yet, one of the most important areas of language testing and assessment. It is particularly important because of its potential wash-back effects on classroom practices. Given the fact that listening tests play a great role in assessing the language proficiency of students, they are expected to enjoy a high level of construct validity. The present study was dedicated to investigating the construct validity of three different test formats, namely, multiple-choice, gap filling on summary (also called listening summary cloze, and fill-in-the-blank, used to evaluate the listening comprehension of EFL learners. In order to achieve the purpose of the study, three passages with relatively similar readability levels were used for the construction of 9 listening tests, that is, each appeared in three formats. Following a counter-balanced design, the tests were administered to 91homogeneous EFL learners divided into three groups. The statistical analysis of the results revealed that the multiple-choice test enjoyed the highest level of construct validity. Moreover, a repeated measure one-way ANOVA demonstrated that the fill-in-the-blank task was the most difficult with the MC test as the easiest for the participants.

    Dynamic testing typically involves specific interventions for a test to assess the extent to which test performance can be modified, beyond level of baseline (static) performance. This study used a dynamic version of the Wisconsin Card Sorting Test (WCST) that is based on cognitive remediation techniques within a test-training-test procedure. From results of previous studies with schizophrenia patients, we concluded that the dynamic and static versions of the WCST should have different construct validity. This hypothesis was tested by examining the patterns of correlations with measures of executive functioning, secondary verbal memory, and verbal intelligence. Results demonstrated a specific construct validity of WCST dynamic (i.e., posttest) scores as an index of problem solving (Tower of Hanoi) and secondary verbal memory and learning (Auditory Verbal Learning Test), whereas the impact of general verbal capacity and selective attention (Verbal IQ, Stroop Test) was reduced. It is concluded that the construct validity of the test changes with dynamic administration and that this difference helps to explain why the dynamic version of the WCST predicts functional outcome better than the static version.

    The purpose of the U.S. Department of Energy Office of Nuclear Energy’s Light Water Reactor Sustainability (LWRS) Program is to develop technologies and other solutions that can improve the reliability, sustain the safety, and extend the operating lifetimes of nuclear power plants (NPPs) beyond 60 years. Since many important safety structures in an NPP are constructed of concrete, inspection techniques must be developed and tested to evaluate the internal condition. In-service containment structures generally do not allow for the destructive measures necessary to validate the accuracy of these inspection techniques. This creates a need for comparative testing of the various nondestructive evaluation (NDE) measurement techniques on concrete specimens with known material properties, voids, internal microstructure flaws, and reinforcement locations. A preliminary report detailed some of the challenges associated with thick reinforced concrete sections and prioritized conceptual designs of specimens that could be fabricated to represent NPP concrete structures for using in NDE evaluation comparisons. This led to the construction of the concrete specimen presented in this report, which has sufficient reinforcement density and cross-sectional size to represent an NPP containment wall. Details on how a suitably thick concrete specimen was constructed are presented, including the construction materials, final nominal design schematic, as well as formwork and rigging required to safely meet the desired dimensions of the concrete structure. The report also details the type and methods of forming the concrete specimen as well as information on how the rebar and simulated defects were embedded. Details on how the resulting specimen was transported, safely anchored, and marked to allow access for systematic comparative NDE testing of defects in a representative NPP containment wall concrete specimen are also given.

    Full Text Available During the last couple of years, there has been a tendency to include more and more political goals into public procurements, such as environmental and societal considerations. This can result in higher prices paid by the public sector compared with similar procurements in the private sector. The decision makers at local level are elected and should represent the interest of their communities and voters, which includes promoting regional/local companies and economic development. This task can sometimes get into conflict with public procurement law or the political goals of a central government. (original abstract

    2006-01-01

    The procurement of the ITER divertor is planned to start in 2009. On the basis of the present common understanding of the sharing of the ITER components, the Japanese Participating Team (JAPT) will supply the outer vertical target, the Russian Federation (RF) PT the dome liner and will perform the high heat flux testing, the EU PT will supply the inner vertical targets and the cassette bodies, including final assembly of the divertor plasma-facing components (PFCs). The manufacturing of the PFCs of the ITER divertor represents a challenging endeavor due to the high technologies which are involved, and due to the unprecedented series production. To mitigate the associated risks, special arrangements need to be put in place prior to and during procurement to ensure quality and to keep to the time schedule. Before procurement can start, an ITER review of the qualification and production capability of each candidate PT is planned. Well in advance of the assumed start of the procurement, each PT which would like to contribute to the divertor PFC procurement, should first demonstrate its technical qualification to carry out the procurement with the required quality, and in an efficient and timely manner. Appropriate precautions, like subdivision of the procurement into stages, are also to be adopted during the procurement phase to mitigate the consequences of possible unexpected manufacturing problems. In preparation for writing the procurement specification for the vertical targets, the topic of setting acceptance criteria is also being addressed. This activity has the objective of defining workable acceptance criteria for the PFC armour joints. A complete set of analyses is also in progress to assess the latest design modifications against the design requirements. This task includes neutronic, shielding, thermo-mechanical and electromagnetic analyses. More than half of the ITER plasma parameters that must be measured and the related diagnostics are located in the

    For γN→ΠN and γd→pn scattering experiments at the PHOENICS detector, a new 'bonn frozen spin target' (BOFROST) is developed. The target with a maximum volume of 30 cm 3 is cooled in a vertical 3 He- 4 He dilution kryostat. The lowest temperature of the dilution kryostat in the frozen spin mode should be 50 mk. In a first stage, the magnet system consist of two superconducting solenoids: A polarisation magnet with a maximum field of 7 T with a homogenity of 10 -5 over the target area and a 'vertical holding' magnet with a maximum field in the target area of 0.57 T. This work describes the construction and the set-up of the 'frozen spin target' in the laboratory and the first tests of the dilution kryostat and the superconducting magnet system. (orig.) [de

    The need for wearable devices for thermal monitoring is rising. These devices could be used to continuously monitor patients for breast cancer investigation or vascular, dermatological and rheumatic disorders, in viability studies, or during physical exercise. We designed and constructed a wearable device for skin-contact thermography that uses integrated silicon sensors. The device was validated using a phantom with a dynamic bench test. The thermal resolution was greater than 0.030'C, and the spatial resolution was equal to 1.6x10-5 m'2. We also investigated the device's performance on five clinical subjects. Results of these studies showed a maximal error of less than 0.10'C in each evaluation [it

    1987-01-01

    As the nuclear industry shifts from a construction to an operations orientation, a number of fundamental changes have occurred in the type of safety-related procurements and the manner in which the utilities accomplish these procurements. Specifically, procurements have shifted from the purchase of large systems and components by architect-engineers, and nuclear steam supply system (NSSS) suppliers to the procurement by utilities of subassemblies, individual pieces of equipment (e.g., breakers, relays), and small parts for repairing individual pieces of equipment. To ensure that equipment will continue to perform its intended function and to satisfy regulatory requirements utilities must consider several things: (1) does the equipment perform a safety function; (2) does the replacement part affect the safety function; and (3) does the replacement part affect the seismic or environmental qualification. If the answer to any of these questions is yes, the purchaser has two alternatives. He may procure the item as safety-related and require the supplier or manufacturer to comply with all the applicable technical and quality requirements or he may purchase the item commercial grade and perform the necessary inspections and tests to ensure the item meets the requirements, i.e., dedicate the item

    Rapid and inexpensive phytotoxicity bioassays for winery wastewater (WW) are important when designing winery wastewater treatment systems involving constructed wetlands. Three macrophyte wetland species (Phragmites australis, Schoenoplectus validus and Juncus ingens) were tested using a pot experiment simulating a wetland microcosm. The winery wastewater concentration was varied (0.5%, 5%, 10%, 25%, 50%, 75% and 100%) and pH was corrected for some concentrations using lime as an amendment. The tolerance of the three aquatic macrophytes species to winery wastewater was studied through biomass production, total chlorophyll and nitrogen, phosphorous and potassium tissue concentrations. The results showed that at greater than 25% wastewater concentration all the macrophytes died and that Phragmites was the least hardy species. At less than 25% wastewater concentration the wetland microcosms were effective in reducing chemical oxygen demand, phenols and total soluble solids. We also evaluated the performance of two laboratory phytotoxicity assays; (1) Garden Cress (Lepidium sativum), and (2) Onion (Allium coepa). The results of these tests revealed that the effluent was highly toxic with effective concentration, EC(50), inhibition values, as low as 0.25%. Liming the WW increased the EC(50) by 10 fold. Comparing the cress and onion bioassays with the wetland microcosm results indicated that the thresholds for toxicity were of the same order of magnitude. As such we suggest that the onion and cress bioassays could be effectively used in the wine industry for rapid wastewater toxicity assessment.

    Phototoxicity corresponds to the acute toxic response induced after skin exposure 'in vivo' and 'ex vivo' to certain chemicals and subsequent exposure to irradiation. Phototoxicity 'in vitro' assay is determined by viability of fibroblasts BALB/c 3T3 exposed to chemicals in the presence and absence of light. Substances identified as phototoxic are susceptible to 'in vivo' phototoxicity (OECD 432, 2004). A chamber was developed and constructed according to the guidelines OECD Toxicity Guide - 432 and ®ECVAM DB-ALM: INVITTOX N. 78. The chamber was built in stainless steel frame, with UVA lamps and dark area for negative control. The tests to qualify the chamber were performed with Sodium Lauryl Sulfate, recommended by the guides aforementioned, as negative control; and Bergamot oil (Givaudan-Roche), as positive control. Bergamot, Citrus bergamia, has, as major component, Bergapten responsible for its photosensitive activity. Both samples were diluted in Phosphate Buffered Saline with concentrations between 0.005 and 0.1 mg/mL, which were calculated by the dilution factor 1.47. These tests were performed over fibroblast BALB/c 3T3 culture and submitted to phototoxicity assay with MTS dye, under spectrophotometric reading, which allows determining the Photo Irritation Factor (PIF), what suggests that a substance with a PIF<2 predicts no phototoxicity; PIF>2 and <5 provides likely phototoxicity and PIF>5 provides phototoxicity. Sodium Lauryl Sulfate presented a PIF=1, being in accordance with the OECD. Bergamot oil has shown to be likely phototoxic with a PIF=2,475. These results provide that the chamber is qualified to be used to perform phototoxicity tests with assurance and security. (author)

    The use of area-oriented work breakdown structures has been proven as a very useful tool for supporting the 'scope detailing' processes in construction projects. This practice allows the definition of intermediate work packages, assisting in the distribution of the scope to be executed within the different team members (or subcontractors), and also allowing the definition of a basic construction strategy based on the main project constraints reflected in each physical area (delivery lead-time of long lead items, for example), to be used as a guide for developing a preliminary master schedule for engineering e procurement activities with a better alignment with the construction strategy. In this way the detailed engineering activities can be developed based on this structure allowing, for example, the possibility of issue piping isometrics and plants under this structure. It's common to split the scope according to the physical location on the eve of starting the field activities as a way to identify the workfaces at the time of the development of 'execution plans' for field activities. However, since this stage much of the engineering activities are already in progress, or even completed, the likelihood of conflicting strategies, such as choosing to start the installation of piping in areas that do not have availability of design documents or required material is considerably higher. Therefore, this study has the intention to discuss about the use of this practice in the early stages of the detailed engineering phase and show the practical impacts of the application of this concept, showing the results obtained with this strategy in oil refining process plant EPC project carried out by Promon Engineering.

    320 In-vessel water cooled stainless steel panels, poloidal closure plates and pumping gap panels, covering an area of approximately 100 m{sup 2}, are used in Wendelstein7-X to protect the plasma vessel. The panels are manufactured at Deggendorf, Germany by MAN Diesel and Turbo SE. The panels consist of a laser welded sandwich of stainless steel plates together with a labyrinth of cooling channels and have a complicated geometry to fit the plasma vessel of Wendelstein 7-X. The hydraulic and mechanical stability requirements whilst maintaining the tight tolerances for the shape of the components are very demanding. The panels are designed to operate at up to an average heat load of 100 kW/m{sup 2} and a maximum heat load of 200 kW/m{sup 2} with a water velocity of approximately 2 m s{sup -1}. High heat flux testing of an un-cooled panel at a time averaged load of 200 kW/m{sup 2} for 10 s were successfully performed to support the start up phase of Wendelstein 7-X operation. Extensive testing both during manufacture and after delivery to IPP-Garching demonstrates the suitability of the delivered panels for their purpose.

High heat flux testing of an un-cooled panel at a time averaged load of 200 kW/m 2 for 10 s were successfully performed to support the start up phase of Wendelstein 7-X operation. Extensive testing both during manufacture and after delivery to IPP-Garching demonstrates the suitability of the delivered panels for their purpose.

    Gasparotto, M.

    2006-01-01

    Over the past few years the technology activities of the European fusion programme have principally been devoted to: a) the completion of design and R (and) D studies in preparation for the procurement of ITER systems and components in close collaboration with the ITER team and according to the ITER design and schedule; b) provision of support to European industry and associations in key areas of fusion R (and) D to ensure a competitive and timely approach to the planned procurement. The EU contribution to ITER design and R (and) D activities has been maintained at a significant level with the objectives of: · continuing, and in some areas expanding, the effort in areas where design and R (and)D are still required: in particular in Machine Assembly, Remote Handling, ITER Test Blanket Modules, Diagnostics, Heating and Current Drive Systems. · continuing and completing manufacturing R (and)D to determine the most technically and cost affective manufacturing methods for ITER components to be built in Europe. · preparing new test facilities needed during ITER construction (DIPOLE, HELOKA, DTP-2, ECRH Test Facility, Fatigue Testing Facility). · supporting the European site preparation process and the preparation of safety and licensing documentation for ITER in Cadarache. · maintaining support to EU industries in R (and) D activities of relevance to fusion. To support the ITER Design activities and to prepare for the provision of timely answers to key issues, which may be raised during the ITER design review, support from specialized companies has been set-up in the fields of Civil and General Plant Engineering, Mechanical Engineering / Components, Mechanical Engineering / Systems (and) Plants, Remote Handling (and) Assembly, Electrical Engineering, Nuclear Safety Engineering. In recent years major efforts have been directed towards the technology development of the ITER components for which procurement can be launched during the first years of the construction

  11. Framework for Structuring Procurement Contracts

    Directory of Open Access Journals (Sweden)

    Lena Borg

    2014-12-01

    Full Text Available The aim of this paper is to propose a new framework for structuring contract types and payment methods. Concerning procurement contracts, the first important new feature of this framework is a stepwise structure with three main steps in the contract design: (1 what will be procured—should the contract only include construction, or should it include both construction and operation/maintenance (2 who will do the detailed design of the premise and (3 how many contractors will the client use? The second important new feature of this framework is that both step 2 and step 3 include a continuum of alternatives. Concerning payment methods, the new framework is primarily based on how the specific risks of the project are shared. These frameworks can be useful for policy formulation in that they can help to avoid some problematic ways of formulating policies.

  12. Traditional Procurement is too Slow

    Directory of Open Access Journals (Sweden)

    Ann Kong

    2012-11-01

    Full Text Available This paper reports on an exploratory interview survey of construction project participants aimed at identifying the reasons for the decrease in use of the traditional, lump-sum, procurement system in Malaysia. The results show that most people believe it is too slow. This appears to be in part due to the contiguous nature of the various phase and stages of the process and especially the separation of the design and construction phases. The delays caused by disputes between the various parties are also seen as a contributory factor - the most prominent cause being the frequency of variations, with design and scope changes being a particular source of discontent. It is concluded that an up scaling of the whole of the time related reward/penalty system may be the most appropriate measure for the practice in future.

  13. Construction and Testing of orfA +/- FIV Reporter Viruses

    Directory of Open Access Journals (Sweden)

    Eric M. Poeschla

    2012-01-01

    Full Text Available Single cycle reporter viruses that preserve the majority of the HIV-1 genome, long terminal repeat-promoted transcription and Rev-dependent structural protein expression are useful for investigating the viral life cycle. Reporter viruses that encode the viral proteins in cis in this way have been lacking for feline immunodeficiency virus (FIV, where the field has used genetically minimized transfer vectors with viral proteins supplied in trans. Here we report construction and use of a panel of single cycle FIV reporter viruses that express fluorescent protein markers. The viruses can be produced to high titer using human cell transfection and can transduce diverse target cells. To illustrate utility, we tested versions that are (+ and (- for OrfA, an FIV accessory protein required for replication in primary lymphocytes and previously implicated in down-regulation of the primary FIV entry receptor CD134. We observed CD134 down-regulation after infection with or without OrfA, and equivalent virion production as well. These results suggest a role for FIV proteins besides Env or OrfA in CD134 down-regulation.

  14. Collaborative procurement for developing a sustainable campus

    Nifa, Faizatul Akmar Abdul; Rahim, Syukran Abdul; Rani, Wan Nurul Mardiah Wan Mohd; Ismail, Mohd. Noorizhar

    2016-08-01

    It is particularly challenging to achieve sustainability in campus universities, where a high volume of users and activities has made it more imperative to promote green buildings that reduce energy and water consumption while having a minimal carbon footprint. At present, the frameworks for sustainable campus have seldom focused on the project procurement method which would improve construction team integration in developing the physical aspect of campus development. Therefore, in response to that challenge, this paper investigates how the delivery team, responsible for the design and construction of a project, can be integrated to work together more efficiently and more using the collaborative procurement method known as partnering. This paper reports part of a previous research and sets the base for ongoing research on the critical factors in partnering for sustainable campus development. The outcome or result of this study will meet and support the requirement for construction, maintenance, and operation process for universities towards sustainable building/campus in the future.

    Full Text Available Research with new versions of the Bender Gestalt Test (TGB has hardly attracted attention to the researchers of the Hispanic world, onsidering that this test is one of the most widely used psychological assessments. This study evaluates the construct validity of the modified version of TGB for children, elative to sustainedattention assessed by the Caras Test. Both tests were applied to 90 children, aged between 5 and 8, in standardized conditions. The esults indicate that the shared variance between the two measures is zero, even when applied disattenuated correlations for measurement error; also, no non-linear patterns were detected between the two variables. These correlations were consistent in the total sample and among subgroups of children. We discuss these results with respect to the limits of validity of this modified version of TGB in the Spanish language.

    Dubbs, J.D.; Kreinbrink, K.

    1994-01-01

    Air Products and CVI collaborated to design, construct and commission a refrigerator, test stands and integrated control system for the General Dynamics Collider Dipole Magnet Cold Test Facility (CTF) in Hammond, LA. The original project schedule required the cold test facility to be operational within 17 months of the notice to proceed. Midway through the project, changes in General Dynamics magnet testing requirements necessitated doubling the plant capacity, but the on stream date for the initial capacity increment could not be relaxed. The Air Products/CVI team had to adapt the project execution strategy to mitigate the schedule impact of the expansion in a cost effective manner without impacting system functionality, quality or safety. An equally challenging aspect of the job was that the (CTF) was being designed while several major systems that would interface with the CTF were being engineered. General Dynamics, Air Products and CVI had to work very closely to manage the interface issues. The teams efforts were very successful. The Hammond refrigerator/liquifier was started up on schedule. The first two test stands are currently being commissioned and will be on stream just six weeks later than the pre-expansion schedule target and all four test stands will be operational in time to support General Dynamics magnet testing requirements

    Procurement of items and services is one of the important elements during the design and construction of Nuclear Power Plants. The purchaser has to establish and implement controls over the procurement process to ensure that the quality criteria, quality level and other quality requirements specified for the particuliar item or service are taken into account. The effect on safety of an error in service or the malfunction of an item is the most important factor to be considered in determining the extent of quality assurance efforts. A typical example of a procurement process will be demonstrated for safety related mechanical components. (orig./RW)

    The construction of modules and the assembly of the calorimeter for CHORUS, an experiment that searches for ν μ ν τ oscillation, have been completed. Within the experiment, the calorimeter is required to measure the energy of hadronic showers produced in neutrino interactions with a resolution of similar 30%/√(E(GeV)). To achieve this performance, the technique, developed in recent years, of embedding scintillating fibers of 1 mm diameter into a lead matrix has been adopted for the most upstream part of the calorimeter. A more conventional system, of alternating layers of lead and scintillator strips, was used for the rest. Details of module construction as well as results obtained when modules were exposed to electron and muon beams are presented. ((orig.))

    2014-10-01

    Organ procurement from executed prisoners in China is internationally condemned, yet this practice continues unabated in 2014. This is despite repeated announcements from Chinese authorities that constructive measures have been undertaken to conform to accepted ethical standards. While there is unanimous agreement on the unethical nature of using organs from executed prisoners, due to its limitations on voluntary and informed consent, there is insufficient coverage of forced organ procurement from prisoners of conscience without consent. Strategies to influence positive change in China over the last few decades have failed to bring this practice to an end. While organ donation and transplantation services in China have undergone considerable structural changes in the last few years, fundamental attempts to shift practice to ethically sourced organs have floundered. In this article, we discuss the organ trade in China, reflect upon organ procurement from executed prisoners (including both capital prisoners and prisoners of conscience) and provide an overview of contradictory Chinese efforts to halt forced organ procurement from executed prisoners. Finally, we highlight current actions being taken to address this issue and offer comprehensive recommendations to bring this ethically indefensible practice to an immediate end. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

  5. Design, construction and testing of a radon experimental chamber

    International Nuclear Information System (INIS)

    Chavez B, A.; Balcazar G, M.

    1991-10-01

    To carry out studies on the radon behavior under controlled and stable conditions it was designed and constructed a system that consists of two parts: a container of mineral rich in Uranium and an experimentation chamber with radon united one to the other one by a step valve. The container of uranium mineral approximately contains 800 gr of uranium with a law of 0.28%; the radon gas emanated by the mineral is contained tightly by the container. When the valve opens up the radon gas it spreads to the radon experimental chamber; this contains 3 accesses that allow to install different types of detectors. The versatility of the system is exemplified with two experiments: 1. With the radon experimental chamber and an associated spectroscopic system, the radon and two of its decay products are identified. 2. The design of the system allows to couple the mineral container to other experimental geometries to demonstrate this fact it was coupled and proved a new automatic exchanger system of passive detectors of radon. The results of the new automatic exchanger system when it leave to flow the radon freely among the container and the automatic exchanger through a plastic membrane of 15 m. are shown. (Author)

    The research reactor FRM-II of the Technische Universitaet Muenchen is now ready for the nuclear start-up, but still waiting for the operational license. The high-flux neutron-source FRM-II (8 x 10 14 n/(s cm 2 ) is a unique tool for solid state physics and materials research by neutron scattering, positron annihilation experiments and activation analysis, as well as for fundamental physics, isotope production, silicone doping, cancer therapy by irradiation with fission neutrons and for tomography with fast and thermal neutrons. Reactor built in facilities as a hot source, a cold source, an uranium loaded converter plate producing an intense beam of fission neutrons, allow to expand the range of usable neutron energies far beyond the thermal spectrum. In addition, a source providing an intense beam of fission products is planned to be constructed by the Ludwig-Maximilians-Universitaet Muenchen and a source of ultra cold neutrons is planned by the Physics Department of the Technische Universitaet Muenchen. The reactor is already prepared for both of these facilities. (author)

  7. Construction and test of a polarized proton target

    International Nuclear Information System (INIS)

    Aures, R.

    1983-12-01

    This work describes experiments in which for the first time a proton target has been constructed which is polarized by the ''brute-force'' method. This method requires very low temperatures and high magnetic fields. The low temperatures (down to 10 mK) are obtained by a 3 He/ 4 He dilution refrigerator, the magnetic field (up to 9 T) is produced by a superconducting split pair magnet. The proton target has a volume of about 18 cm 3 and consists of pressed titaniumhydride powder, which has a titanium/-hydrogen ratio of 1:1,96. The hydrogen content is 1,3 mol. Titaniumhydride has the advantage of sufficient heat conductivity at low temperatures and a very high proton density. The heat conductivity of the sample is measured, with and without the presence of a magnetic field. Thermodynamical measurements and adiabatic demagnetisation experiments proved quantitatively the polarization of the protons. The polarization of the proton has been measured in a transmission experiment using polarized neutrons of 1.2 MeV. The result shows a good agreement of theoretical and actual polarization. From the results it can be concluded, that this sample can be used successfully as a polarized proton target for neutron scattering experiments to measure spin-correlations. (orig.) [de

    Full Text Available Psychology has recently seen a noticeable increase in interest for implicit measures of attitudes and personality characteristics. The far most known implicit measure is the Implicit Association Test – IAT. We adapted this test in order to assess the Big Five personality dimensions (B5 IAT. We examined B5 IAT measurement characteristics on two samples. Based on the findings of the first sample (N = 62, improvements were made in the B5 IAT, to be tested again on another sample (N = 75. The two studies have shown similar results. The reliabilities of the personality dimensions measured with the B5 IAT failed to achieve a satisfactory level in most cases. The reason probably lies in a lower adequacy of certain stimuli and in the considerable length of the test procedure. The convergent validity of the B5 IAT with explicit measures of personality was low, which may be due to different structures underlying implicit and explicit measures. Results obtained on the first sample have shown that the correlations between IAT adjectives are adequately explained by five latent dimensions. However, these results should be interpreted with caution due to B5 IAT low reliabilities and small sample sizes. The second sample proved to be very unstable, thus the confirmatory factor analysis could not be conducted. Since this is the first attempt to adapt B5 IAT to Slovene language, it is hardly surprising that the results are not entirely consistent with the expectations. As implicit measures currently fail to meet relevant psychometric characteristics, they are not yet applicable in psychological practice. Nevertheless, they have great potential in exploring personality and individual differences, as they overcome many limitations of existing explicit measures.

    Several studies suggest that, in practice, service procurement is more challenging than goods procurement. The underlying but largely implicit argument is that the procurement process for services involves higher buyer uncertainty and therefore requires extra efforts to mitigate this uncertainty.

    The solid waste form test and inspection facility is a facility to test and inspect the characteristics of waste forms, such as homogenity, mechanical structure, thermal behaviour, water resistance and leachability. Such kinds of characteristics in waste forms are required to meet a certain conditions for long-term storage or for final disposal of wastes. The facility will be used to evaluate safety for the disposal of wastes by test and inspection. At this moment, the efforts to search the most effective management of the radioactive wastes generated from power plants and radioisotope user are being executed by the people related to this field. Therefore, the facility becomes more significant tool because of its guidance of sucessfully converting wastes into forms to give a credit to the safety of waste disposal for managing the radioactive wastes. In addition the overall technical standards for inspecting of waste forms such as the standardized equipment and processes in the facility will be estabilished in the begining of 1990's when the project of waste management will be on the stream. Some of the items of the project have been standardized for the purpose of localization. In future, this facility will be utilized not only for the inspection of waste forms but also for the periodic decontamination apparatus by remote operation techniques. (Author)

    2008-12-01

    Corruption in emergency procurement reduces the resources available for life-saving operations, lowers the quality of products and services provided, and diverts aid from those who need it most.(1) It also negatively influences public support for humanitarian relief, both in the affected country and abroad. This paper aims to unpack and analyse the following question in order to mitigate risk: how and where does corruption typically occur, and what can be done? Suggested strategies reflect a multi-layered approach that stresses internal agency control mechanisms, conflict-sensitive management, and the need for common systems among operators.

  13. Construction and Tests of Modules for the ATLAS Pixel Detector

    CERN Document Server

    AUTHOR|(CDS)2068490

    2003-01-01

    The ATLAS Pixel Detector is the innermost layer of the ATLAS tracking system and will contribute significantly to the ATLAS track and vertex reconstruction. The detector consists of identical sensor-chip-hybrid modules, arranged in three barrels in the centre and three disks on either side for the forward region. The position of the pixel detector near the interaction point requires excellent radiation hardness, mechanical and thermal robustness, good long-term stability, all combined with a low material budget. The pre-production phase of such pixel modules has nearly finished, yielding fully functional modules. Results are presented of tests with these modules.

    Lang, Philipp-Michael

    2015-01-01

    The study of High Energy Density Matter (HEDM) in the laboratory makes great demands on the diagnostics because these states can usually only be created for a short time and usual diagnostic techniques with visible light or X-rays come to their limit because of the high density. The high energy proton radiography technique that was developed in the 1990s at the Los Alamos National Laboratory is a very promising possibility to overcome those limits so that one can measure the density of HEDM with high spatial and time resolution. For this purpose the proton microscope PRIOR (Proton Radiography for FAIR) was set up at GSI, which not only reproduces the image, but also magnifies it by a factor of 4.2 and thereby penetrates matter with a density up to 20 g/cm 2 . Straightaway a spatial resolution of less than 30 μm and a time resolution on the nanosecond scale was achieved. This work describes details to the principle, design and construction of the proton microscope as well as first measurements and simulations of essential components like magnetic lenses, a collimator and a scintillator screen. For the latter one it was possible to show that plastic scintillators can be used as converter as an alternative to the slower but more radiation resistant crystals, so that it is possible to reach a time resolution of 10 ns. Moreover the characteristics were investigated for the system at the commissioning in April 2014. Also the changes in the magnetic field due to radiation damage were studied. Besides that an overview about future applications is given. First experiments with Warm Dense Matter created by using a Pulsed Power Setup have already been performed. Furthermore the promising concept of combining proton radiography with particle therapy has been investigated in context of the PaNTERA project. An outlook on the possibilities with future experiments at the FAIR accelerator facility is given as well. Because of higher beam intensity an energy one can expect even

    The Gamma-ray Large Area Space Telescope represents a great advance in space application of silicon detectors. With a surface of 80 m{sup 2} and about 1 M readout channels it is the largest silicon tracker ever built for a space experiment. GLAST is an astro-particle mission that will study the mostly unexplored, high energy (20 MeV-300 GeV) spectrum coming from active sources or diffused in the Universe. The detector integration and test phase is complete. The full instrument underwent environmental testing and the spacecraft integration phase has just started: the launch is foreseen in late 2007. In the meanwhile the spare modules are being used for instrument calibration and performance verification employing the CERN accelerator complex. A Calibration Unit has been exposed to photon, electron and hadron beams from a few GeV up to 300 GeV. We report on the status of the instrument and on the calibration campaign.

    A jet-cell based vertex chamber has been built for the D OE experiment at Fermilab and operated in a test beam there. Low drift velocity and diffusion properties were achieved using CO 2 (95%)-ethane(5%) at atmospheric pressure. The drift velocity is found to be consistent with [9.74+8.68(|E|-1.25)] μm/nsec where E is the electric field strength in (kV/cm < |E| z 1.6 kV/cm.) An intrinsic spatial resolution of 60 μm or better for drift distances greater than 2 mm is measured. The track pair efficiency is estimated to be better than 90% for separations greater than 630 μm. 8 refs., 6 figs., 1 tab

    We first describe the realisation of a scintillation spectrometer based on the 'Fast-slow' coincidences technique. The counters use 56 A.V.P. fast photomultipliers. The fast coincidences unit can also be used as time-to- height pulses converter. The resolving time, with two NaI crystals, is about 14 nanoseconds. We show, at the end, the measurements which can be undertaken with our apparatus: β-γ or γ-γ coincidences, 'Sum-spectra', life time measurements, β-γ or γ-γ directional angular correlation measurements (with detection or not of the linear polarization) and we give, for each case, the results of test-measurements.

    The new particle accelerator project Spiral 2 at GANIL (“Grand Accélérateur d’Ions Lourds, i.e. National Large Heavy Ion Accelerator) in Caen (France) is a very large installation, intended to serve fundamental research in nuclear physics. The heart of the future machine features a superconductor linear accelerator, delivering a beam until 20Mev/A, which are then used to bombard a matter target. The resulting reactions, such as fission, transfer, fusion, etc. will generate billions of exotic nuclei. To achieve acceleration of the beam, 26 cavities which are placed inside cryomodules at helium cryogenic temperature will be used. AL-AT (Air Liquide Advanced Technologies) takes part to the project by supplying cryogenic plant. The plant includes the liquefier associated to its compressor station, a large dewar, a storage tank for helium gas and transfer lines. In addition, a helium recovery system composed of recovery compressor, high pressure storage and external purifier has been supplied. Customized HELIAL LF has been designed, manufactured and tested by AL-AT to match the refrigeration power need for the Spiral 2 project which is around 1300 W equivalent at 4.5 K.

    1993-01-01

    In Feb. 1993, the Solar Power Satellite (SPS) Working Group from ISAS, Japan will launch a sounding rocket into low earth orbit to perform two activities: collect scientific information on the high power microwave-ionosphere interaction, and demonstrate microwave power transmission in space at 2.45 GHz. The SPS Working Group announced an open invitation to international agencies willing to collaborate with the Microwave Energy Transmission in Space (METS) experiment in a number of categories. Under the sponsorship of the NASA's Lewis Research Center, the Center for Space Power located at Texas A&M University joined the experiment by producing a microwave rectifying receiving antenna (rectenna). The rectenna is a special type of receiving antenna with unique properties and characteristics. The rectenna's main purpose is to efficiently convert microwave power into DC power. The rectenna is an advanced component in microwave power beaming technology developed for 2.45 GHz. The state-of-the-art rectenna for this frequency consists of dipole antennas, filter circuits, and transmission lines etched on a thin layer of Kapton film. The format of the thin film rectenna is ideally suited for space applications. Thin film rectennas have a low specific mass of approximately 1 kg/kW. The main component of the rectenna is the rectifying diode. High conversion efficiencies (90 percent) in microwave to DC power are capable with special Schottky barrier diodes correctly located in the rectenna circuitry. The theory of operation of the 2.45 GHz rectenna is explained. Experimental test results on the METS rectenna are presented. The packaging of the rectenna is also discussed to meet space qualifications.

    Full Text Available The delivery of services through the procurement of goods and services requires proper strategic leadership and management processes. Inappropriate planning, under-spending of budgets and ineffective procurement form part of the root causes of poor service delivery, as this restricts the movement of resources to the right places. This study identified the leading procurement practices as: procurement strategy and leadership, the procurement process, human resource management, procurement information systems, supplier management and procurement performance management. These practices were then tested in public entities, mainly in Gauteng Province, South Africa, to determine the extent to which they are applied. The study found that there is a major divide between the perception of the level of application of the leading practices and actual implementation. Processes, skills, performance management, information technology (IT systems and supplier management are applied inadequately or inappropriately. Most entities thus show a poor understanding of customer needs and there seems to be a general lack of customer focus. The study highlighted the best practice areas in which public entities are able to focus their efforts to better achieve excellent customer service and thus service delivery.

    2016-12-01

    Full Text Available Against the backdrop of increasing adoption of e-Procurement in supply chain management, there is a need for adequate knowledge of the factors that influence the decision by organizations in the building industry to use e-Procurement. This study aims to fill the knowledge gap through investigating the factors influencing e-Procurement adoption based on the data sourced in a questionnaire survey involving 213 organizations in the building industry. The survey was conducted between June and November 2015 in Nigeria. Descriptive statistics, factor and categorical regression analyses were used to analyze the data. The results show that the three most important factors influencing the adoption of e-Procurement amongst the participants, in order of importance, were: the benefits of e-Procurement in enhancing efficiency in project delivery; eliminating geographic barriers and effective communication among project team members. The 29 factors were investigated in seven different dimensions - the benefits of e-Procurement use; level of awareness on e-Procurement in construction; and the availability and cost of e-Procurement applications emerged as the three most significant predictors of e-Procurement adoption in the survey. The study concludes by identifying strategies that should be engaged in increasing the uptake and maximizing the benefits of e-Procurement in the Nigerian building industry.

    A number of studies concerning a cavern type disposal facility have been carried out for disposal of low level radioactive waste mainly generated by power plant decommissioning in Japan. The disposal facility is composed of an engineered barrier system with concrete pit and bentonite buffer, and planed to be constructed in sub-surface 50 - 100 meters depth. Though the previous studies have mainly used laboratory and mock-up tests, we conducted a demonstration test in a full-size cavern. The main objectives of the test were to study the construction methodology and to confirm the quality of the engineered barrier system. The demonstration test was planned as the construction of full scale mock-up. It was focused on a buffer construction test to evaluate the construction methodology and quality control in this paper. Bentonite material was compacted to 1.6 Mg/m 3 in-site by large vibrating roller in this test. Through the construction of the buffer part, a 1.6 Mg/m 3 of the density was accomplished, and the data of workability and quality is collected. (authors)

    To evaluate the construct validity and interrater reliability of 4 simple antigravity tests in a small group of patients with facioscapulohumeral muscular dystrophy (FSHD). Case-control study. University medical center. Patients with various severity levels of FSHD (n=9) and healthy control subjects (n=10) were included (N=19). Not applicable. A 4-point ordinal scale was designed to grade performance on the following 4 antigravity tests: sit to stance, stance to sit, step up, and step down. In addition, the 6-minute walk test, 10-m walking test, Berg Balance Scale, and timed Up and Go test were administered as conventional tests. Construct validity was determined by linear regression analysis using the Clinical Severity Score (CSS) as the dependent variable. Interrater agreement was tested using a κ analysis. Patients with FSHD performed worse on all 4 antigravity tests compared with the controls. Stronger correlations were found within than between test categories (antigravity vs conventional). The antigravity tests revealed the highest explained variance with regard to the CSS (R(2)=.86, P=.014). Interrater agreement was generally good. The results of this exploratory study support the construct validity and interrater reliability of the proposed antigravity tests for the assessment of functional capacity in patients with FSHD taking into account the use of compensatory strategies. Future research should further validate these results in a larger sample of patients with FSHD. Copyright © 2015 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

  19. Bulk material engineering and procurement management of NPS

    Fu Sanhong; Fan Kai

    2005-01-01

    In a nuclear power project, bulk material is often not in an outstanding position, compared to equipment, yet bulk material is one of most difficult part in engineering and procurement management. If the schedule is not in good control, it will seriously hamper the progress of the whole project. The article explores bulk material engineering and procurement management of NPS, illustrated with tables and graphs. First, major difficult aspects of bulk material procurement are described. On one hand, bulk material is really bulky in kind. We must have detail information of manufacturers, manufacture duration, and take good control of bidding schedule. On the other hand, when an order is placed, we need to make clear everything in the procurement package, such as material types, delivery batches, quantity of each batch and delivery schedule, which is a tremendous work. Then, a schedule conflict is analyzed: when an order is placed, the detail type and quantity cannot be defined (since the construction design is not finished yet). To settle this conflict, the concept 'Requirement Schedule Curve' is brought forward, along with the calculation method. To get this curve, we need to make use of the technical data of the reference power station, along with the site construction schedule, to produce a site quantity requirement curve varying from time, for each type of material. Last, based on the 'Requirement Schedule Curve', we are able to build a unified database to control the engineering, procurement, manufacturing and delivery schedule, so as to procure precisely, manufacture on time, and optimize the storage. In this way, the accurate control of bulk material engineering and procurement schedule can be achieved. (authors)

    1980-02-01

    This review report presents the results of an analysis of alternative approaches to the design of a federal photovoltaics procurement program. Advantages and disadvantages of large purchases at fixed prices and smaller purchases for testing and demonstrating the technology are presented. The objectives and possible impacts of these purchase programs on the photovoltaic industry are described. The reactions of the industry to alternative purchase programs were assessed using personal interviews with selected companies currently active in photovoltaics. The report begins with a review of the impacts of federal procurements on other innovations, including the electronics industry, and suggests the relation of these procurements to photovoltaics. The methodology for conducting the interviews is presented next. The results of the interviews are summarized into possible scenarios of future developments in the industry and into discussions of key issues in the design of a procurement program. An appendix on the current structure of the photovoltaic industry is provided.

    This brief paper introduces how the ITER will be built in the international collaboration. The ITER Organization plays a central role in constructing ITER and leading it into operation. Since most of the ITER components are to be provided in-kind from the member countries, integral project management should be scoped in advance of real work. Those include design, procurement, system assembly, testing, licensing and commissioning of ITER.

    1987-01-01

    The PROcurement Management Information System (PROMIS) provides both detailed and summary level information on all procurement actions performed within NASA's procurement offices at Marshall Space Flight Center (MSFC). It provides not only on-line access, but also schedules procurement actions, monitors their progress, and updates Forecast Award Dates. Except for a few computational routines coded in FORTRAN, the majority of the systems is coded in a high level language called NATURAL. A relational Data Base Management System called ADABAS is utilized. Certain fields, called descriptors, are set up on each file to allow the selection of records based on a specified value or range of values. The use of like descriptors on different files serves as the link between the falls, thus producing a relational data base. Twenty related files are currently being maintained on PROMIS.

    2013-10-15

    The enforcement of the European Construction Products Directive (and the more actual Construction Products Regulation) has led to the development of European harmonised standards for assessment of the emission of 'dangerous substances' from construction materials. According to Basic Working Requirement (BWR) number 3, the emissions from construction products to soil and groundwater should not have an unacceptable impact on the environmental quality over the life cycle of the product. In this paper the technical needs and boundary conditions of leaching tests to obtain meaningful and reliable test results are explained. Although this paper will not go into detail on 'impact assessment' and the resulting development of regulatory criteria, we will show that the technical needs and boundary conditions of a test are to some extent dependent on what type of information is needed by regulators for environmental impact assessment. This short paper focuses on explaining the principles of testing leaching behaviour of aggregates, and briefly explains the leaching of size reduced and non-size reduced particles. It provides information for the actual discussions on size reduction before leaching tests.

  13. Procurement engineering - the productivity factor

    1993-01-01

    The industry is several years on the road to implementation of the Nuclear Management and Resources Council (NUMARC) initiatives on commercial-grade item dedication and procurement. Utilities have taken several approaches to involve engineering in the procurement process. A common result for the approaches is the additional operations and maintenance (O M) cost imposed by the added resource requirements. Procurement engineering productivity is a key element in controlling this business area. Experience shows that 400 to 500% improvements in productivity are possible with a 2-yr period. Improving the productivity of the procurement engineering function is important in today's competitive utility environment. Procurement engineering typically involves four distinct technical evaluation responsibilities along with several administrative areas. Technical evaluations include the functionally based safety classification of replacement components and parts (lacking a master parts list), the determination of dedication requirements for safety-related commercial-grade items, the preparation of a procurement specification to maintain the licensed design bases, and the equivalency evaluation of alternate items not requiring the design-change process. Administrative duties include obtaining technical review of vendor-supplied documentation, identifying obsolete parts and components, resolving material nonconformances, initiating the design-change process for replacement items (as needed), and providing technical support to O M. Although most utilities may not perform or require all the noted activities, a large percentage will apply to each utility station.

  14. The organization of organ procurement.

    Prottas, J M

    1989-01-01

    The American organ procurement system has improved and matured in the last five years. At the same time, the basic challenges facing it have remained substantially the same because the moral and legal framework of the system has not changed. Success at organ procurement continues to depend on the voluntary cooperation of medical professionals and the families of potential organ donors. The generosity of the American public is so great that the primary challenge facing organ procurement agencies is obtaining cooperation from hospitals and medical professionals. This calls for a "marketing" orientation aimed at those hospitals and professionals who are most likely to treat potential donors. The last five years have seen a more general acceptance of this appreciation of the central task of organ procurement. As a result, the overall effectiveness of the system has improved, as measured by the number of organs procured on a per capita basis and by the number of multiorgan donors obtained. Much of this improvement can be attributed to the diffusion of organizational techniques and approaches, and this diffusion has been encouraged by the involvement of national organizations and public bodies in the organ procurement community. The system remains uneven in its effectiveness and further improvement is possible. It is also possible that the next general round of improvement will result from the application of businesslike information management and marketing techniques.

    The industry is several years on the road to implementation of the Nuclear Management and Resources Council (NUMARC) initiatives on commercial-grade item dedication and procurement. Utilities have taken several approaches to involve engineering in the procurement process. A common result for the approaches is the additional operations and maintenance (O ampersand M) cost imposed by the added resource requirements.

    In general, the upgrading of requirements for the most different fields of engineering is also characterized by a corresponding effort in testing. In this context especially nondestructive tests of materials are of outstanding importance. In the fields of power plant construction (among others, components for nuclear power plants) as well as petrochemical and chemical industry considered here, almost all nondestructive test methods are applied. This paper discusses not so much theoretical testing problems, but rather test objects as well as specifications and testing equipment. (orig./HP) [de

    2015-01-01

    The management of brain-dead organ donors is complex. The use of inotropic agents and replacement of depleted hormones (hormonal replacement therapy) is crucial for successful multiple organ procurement, yet the optimal hormonal replacement has not been identified, and the statistical adjustment to determine the best selection is not trivial. Traditional pair-wise comparisons between every pair of treatments, and multiple comparisons to all (MCA), are statistically conservative. Hsu's multiple comparisons with the best (MCB) - adapted from the Dunnett's multiple comparisons with control (MCC) - has been used for selecting the best treatment based on continuous variables. We selected the best hormonal replacement modality for successful multiple organ procurement using a two-step approach. First, we estimated the predicted margins by constructing generalized linear models (GLM) or generalized linear mixed models (GLMM), and then we applied the multiple comparison methods to identify the best hormonal replacement modality given that the testing of hormonal replacement modalities is independent. Based on 10-year data from the United Network for Organ Sharing (UNOS), among 16 hormonal replacement modalities, and using the 95% simultaneous confidence intervals, we found that the combination of thyroid hormone, a corticosteroid, antidiuretic hormone, and insulin was the best modality for multiple organ procurement for transplantation.

  1. Experiences for construction and preoperation test of Shimane nuclear power station

    International Nuclear Information System (INIS)

    Niki, Yoshiya; Taniguchi, Takashi.

    1975-01-01

    Shimane nuclear power station of Chugoku Electric Power Company has begun its commercial operation on March 29, 1974 after the construction period of 49.5 months. The fundamental construction process which Chugoku Electric Power Company and Hitachi Ltd. had agreed was 45 month process, which was the readjustment of the construction process which General Electric Company had presented for preceding nuclear power plants in Japan and its results. The achieved construction and test process required 49.5 months with 4.5 months delay. This delay occurred in two points. The one was caused by the ''upside down'' problem of control rods which had been imported from G.E. The another was caused by the restriction of the rate of load increasing. Fuel charging which indicates the substantial finish of construction works, had begun at May 1, 1973 on schedule. Therefore it can be said that the construction works had been carried out just according to the fundamental process. However, analyzing the result of progress, the pressure test of a reactor containment vessel and the set-up and the first pressure test of a reactor pressure vessel led the schedule by about 2 months. On the contrary, the subsequent works delayed by just that leading time. (Tai, I.)

    This final report describes both the engineering development of a DC bioeffects test enclosure for small laboratory animals, and the biological protocol for the use of such enclosures in the testing of animals to determine possible biological effects of the environment associated with HVDC transmission lines. The test enclosure which has been designed is a modular unit, which will house up to eight rat-sized animals in individual compartments. Multiple test enclosures can be used to test larger numbers of animals. A prototype test enclosure has been fabricated and tested to characterize its electrical performance characteristics. The test enclosure provides a simulation of the dominant environment associated with HVDC transmission lines; namely, a static electric field and an ion current density. A biological experimental design has been developed for assessing the effects of the dominant components of the HVDC transmission line environment.

    In order to increase the use of forest fuels, a regional development project was launched in the fall of 2008. The co-ordinator of the project is Metsaekeskus Keski-Suomi (Forestry Centre of Central Finland), while VTT (Technical Research Centre of Finland) is in charge of research and technical development. The aim of this project is to enhance energy wood procurement from early thinnings, to develop the supply chains of pine stump extraction, and to reduce storage losses of energy wood at roadside landings and at terminals. The results of a pre-feasibility study on the first-generation feller-bundler (Fixteri) by Metsaeteho Oy and the Finnish Forest Research Institute indicates that whole-tree bundling might enable undercutting of the current costs of separate procurement of pulp-wood and energy wood from first-thinning stands. The greatest cost-saving potential lies in small-diameter (d{sub 1.3} = 7-10 cm) first-thinning stands, which are currently relatively unprofitable sites for conventional pulpwood procurement based on single-tree harvesting. Preliminary tests of seasoning of whole-tree bundles have been very encouraging. In some cases the moisture content of energy wood bundles has decreased from 55 % to 25 % after about year of seasoning at the roadside (two summers). One of the most promising devices for pine stump harvesting was developed by Karelian Puu ja Metalli Oy. (orig.)

    Full Text Available Inadequately adopted fundamental movement skills (FMS in early childhood may have a negative impact on the motor performance in later life (Gallahue and Ozmun, 2005. The need for an efficient FMS testing in Physical Education was recognized. The aim of this paper was to construct and validate a new FMS test for 8 year old children. Ninety-five 8 year old children were used for the testing. A total of 24 new FMS tasks were constructed and only the best representatives of movement areas entered into the final test product - FMS-POLYGON. The ICC showed high values for all 24 tasks (0.83-0.97 and the factorial analysis revealed the best representatives of each movement area that entered the FMS-POLYGON: tossing and catching the volleyball against a wall, running across obstacles, carrying the medicine balls, and straight running. The ICC for the FMS-POLYGON showed a very high result (0.98 and, therefore, confirmed the test's intra-rater reliability. Concurrent validity was tested with the use of the "Test of Gross Motor Development" (TGMD-2. Correlation analysis between the newly constructed FMS-POLYGON and the TGMD-2 revealed the coefficient of -0.82 which indicates a high correlation. In conclusion, the new test for FMS assessment proved to be a reliable and valid instrument for 8 year old children. Application of this test in schools is justified and could play an important factor in physical education and sport practice.

    Motivation to drink alcohol can be measured in the laboratory using an ad-libitum 'taste test', in which participants rate the taste of alcoholic drinks whilst their intake is covertly monitored. Little is known about the construct validity of this paradigm. The objective of this study was to investigate variables that may compromise the validity of this paradigm and its construct validity. We re-analysed data from 12 studies from our laboratory that incorporated an ad-libitum taste test. We considered time of day and participants' awareness of the purpose of the taste test as potential confounding variables. We examined whether gender, typical alcohol consumption, subjective craving, scores on the Alcohol Use Disorders Identification Test and perceived pleasantness of the drinks predicted ad-libitum consumption (construct validity). We included 762 participants (462 female). Participant awareness and time of day were not related to ad-libitum alcohol consumption. Males drank significantly more alcohol than females (p alcohol consumption (p = 0.04), craving (p alcohol consumption. The construct validity of the taste test was supported by relationships between ad-libitum consumption and typical alcohol consumption, craving and pleasantness ratings of the drinks. The ad-libitum taste test is a valid method for the assessment of alcohol intake in the laboratory.

    Full Text Available The main aim of this article was developed of a test stand to a study physics phenomena accruing at work in a ram water based on the construction recommendations. The experience gained by a number of attempts allowed to the developed construction recommendations that allowed to adjust the test stand to perform various studies of physics phenomena occurring at the work of water ram and easy adaptions to the new requirements. The article includes: the review of the test stands on which performed the study in the history and in the present times, description of the construction recommendations of the universal test stand and the proposal of the test stand developed based on the construction recommendations. Motivation to take up this issue follows from the interest of devices that work in an unconventional way, devices used a renewable energy that can be used in household e.g. to improve their energy balance, delivery water to houses, drinking water for animals, fields irrigation, etc. Analysis of the literature of the water ram, test stands and their performance shown that it is small and typically old development in popular science form. In times of intensive search new sources of renewable energy reactivation of this type equipment may be highly probable.

    Science.gov (United States)

    Thrailkill, Eric A.; Bouton, Mark E.

    2015-01-01

    Instrumental behavior often consists of sequences or chains of responses that minimally include procurement behaviors that enable subsequent consumption behaviors. In such chains, behavioral units are linked by access to one another and eventually to a primary reinforcer, such as food or a drug. The present experiments examined the effects of extinguishing procurement responding on consumption responding after training of a discriminated heterogeneous instrumental chain. Rats learned to make a procurement response (e.g., pressing a lever) in the presence of a distinctive discriminative stimulus; making that response led to the presentation of a second discriminative stimulus that set the occasion for a consumption response (e.g., pulling a chain), which then produced a food-pellet reinforcer. Experiment 1 showed that extinction of either the full procurement-consumption chain or procurement alone weakened the consumption response tested in isolation. Experiment 2 replicated the procurement extinction effect and further demonstrated that the opportunity to make the procurement response, as opposed to simple exposure to the procurement stimulus alone, was required. In Experiment 3, rats learned 2 distinct discriminated heterogeneous chains; extinction of 1 procurement response specifically weakened the consumption response that had been associated with it. The results suggest that learning to inhibit the procurement response may produce extinction of consumption responding through mediated extinction. The experiments suggest the importance of an associative analysis of instrumental behavior chains. PMID:25915751

    Full Text Available Since the declaration of Malaysian independence, the public sector has significantly contributed to the country’s development. In the 1990s, a new procurement system was developed due to CIBD various changes in the construction industry. Since that period, the poor quality of public sector projects has started to attract public attention. This paper describes a study that was conducted to identify the dominant public procurement systems in place, the problems associated with these systems, and the satisfaction level of the industry players in the Malaysian construction industry. The results were drawn from 84 survey responses and interviews with industry players. The public sector is using a traditional system inherited from the British, with an intention to adopt new procurement systems. Aside from the disputes that are present in most systems, the public sector seems to encounter particular problems in relation to capabilities, time, and cost of the major procurement systems used. Traditional work culture and the industry environment influence public sector practice, which accounts for the modifications of each procurement system used. Thus, the full advantages of using an alternative procurement system may not be realised in public sector organizations. This produces an average level of satisfaction gained from the procurement system adopted. As a developing country, Malaysia needs to exert significant efforts to improve the public procurement system.

    1999-01-01

    A large number of the small optics procurements for the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) will be in the form of completely assembled, tested, and cleaned subsystems. These subsystems will be integrated into the NIF at LLNL. To accomplish this task, the procurement packages will include, optical and mechanical drawings, acceptance test and cleanliness requirements. In January 1999, the first such integrated opto-mechanical assembly was received and evaluated at LLNL. With the successful completion of this important trial procurement, we were able to establish the viability of purchasing clean, ready to install, opto-mechanical assemblies from vendors within the optics industry. 32 vendors were chosen from our supplier database for quote, then five were chosen to purchase from. These five vendors represented a cross section of the optics industry. From a ''value'' catalog supplier (that did the whole job internally) to a partnership between three specialty companies, these vendors demonstrated they have the ingenuity and capability to deliver cost competitive, NIF-ready, opto- mechanical assemblies. This paper describes the vendor selection for this procurement, technical requirements including packaging, fabrication, coating, and cleanliness specifications, then testing and verification. It also gives real test results gathered from inspections performed at LLNL that show how our vendors scored on the various requirements.

The use of inotropic agents and replacement of depleted hormones (hormonal replacement therapy is crucial for successful multiple organ procurement, yet the optimal hormonal replacement has not been identified, and the statistical adjustment to determine the best selection is not trivial. Traditional pair-wise comparisons between every pair of treatments, and multiple comparisons to all (MCA, are statistically conservative. Hsu’s multiple comparisons with the best (MCB – adapted from the Dunnett’s multiple comparisons with control (MCC – has been used for selecting the best treatment based on continuous variables. We selected the best hormonal replacement modality for successful multiple organ procurement using a two-step approach. First, we estimated the predicted margins by constructing generalized linear models (GLM or generalized linear mixed models (GLMM, and then we applied the multiple comparison methods to identify the best hormonal replacement modality given that the testing of hormonal replacement modalities is independent. Based on 10-year data from the United Network for Organ Sharing (UNOS, among 16 hormonal replacement modalities, and using the 95% simultaneous confidence intervals, we found that the combination of thyroid hormone, a corticosteroid, antidiuretic hormone, and insulin was the best modality for multiple organ procurement for transplantation.

    2016-11-01

    Full Text Available One of the most important strategic decisions of a company is to choose whether to insource or outsource a particular group of activities or a business function. The trend of outsourcing those activities which do not form a part of the company core competences is becoming more and more present in business practice. The aim of the analysis within this paper is to review the mentioned trend from the position of organizing the company procurement activities. The analysis shows that there is no unique trend concerning outsourcing all logistics activities, which do not form a part of the company core competences. Unlike the majority of other logistics activities, which as non-basic, tend to be outsourced, procurement dominantly stays insourced. Finally, based on the empirical evidence obtained from a survey carried out among 52 companies in Serbia, it is concluded that even if procurement is outsourced, this trend is more present among service than production companies.

    Side-lying hip abductor strength tests are commonly used to evaluate muscle strength. In a 'break' test the tester applies sufficient force to lower the limb to the table while the patient resists. The peak force is postulated to occur while the leg is lowering, thus representing the participant's eccentric muscle strength. However, it is unclear whether peak force occurs before or after the leg begins to lower. To determine intra-rater reliability and construct validity of a hip abductor eccentric strength test. Intra-rater reliability and construct validity study. Twenty healthy adults (26 ±6 years; 1.66 ±0.06 m; 62.2 ±8.0 kg) made two visits to the laboratory at least one week apart. During the hip abductor eccentric strength test, a hand-held dynamometer recorded peak force and time to peak force and limb position was recorded via a motion capture system. Intra-rater reliability was determined using intra-class correlation (ICC), standard error of measurement (SEM), and minimal detectable difference (MDD). Construct validity was assessed by determining if peak force occurred after the start of the lowering phase using a one-sample t-test. The hip abductor eccentric strength test had substantial intra-rater reliability (ICC( 3,3 ) = 0.88; 95% confidence interval: 0.65-0.95), SEM of 0.9%BWh, and a MDD of 2.5%BWh. Construct validity was established as peak force occurred 2.1s (±0.6s; range 0.7s to 3.7s) after the start of the lowering phase of the test (p ≤ 0.001). The hip abductor eccentric strength test is a valid and reliable measure of eccentric muscle strength. This test may be used clinically to assess changes in eccentric muscle strength over time.

    Full Text Available The study deals with the possibility of substituting time- and material-demanding mechanical testing of a bone defect fixation by mathematical modelling. Based on the mechanical model, a mathematical model of bone-implant construct stabilizing experimental segmental femoral bone defect (segmental ostectomy in a miniature pig ex vivo model using 4.5 mm titanium LCP was created. It was subsequently computer-loaded by forces acting parallel to the long axis of the construct. By the effect of the acting forces the displacement vector sum of individual construct points occurred. The greatest displacement was noted in the end segments of the bone in close proximity to ostectomy and in the area of the empty central plate hole (without screw at the level of the segmental bone defect. By studying the equivalent von Mises stress σEQV on LCP as part of the tested construct we found that the greatest changes of stress occur in the place of the empty central plate hole. The distribution of this strain was relatively symmetrical along both sides of the hole. The exceeding of the yield stress value and irreversible plastic deformations in this segment of LCP occurred at the acting of the force of 360 N. These findings are in line with the character of damage of the same construct loaded during its mechanic testing. We succeeded in creating a mathematical model of the bone-implant construct which may be further used for computer modelling of real loading of similar constructs chosen for fixation of bone defects in both experimental and clinical practice.

    Hazardous waste management facilities are required to use approved lining and leak detection systems to prevent the migration of waste into the environment. Synthetic flexible membrane liners (FMLs) have effectively served as the critical barrier for waste containment and fluid migration. The U.S. EPA has established minimum technology requirements for the construction of lined facilities that include detailed and documented Construction Quality Assurance (CQA) plans. The U.S. EPA (EPA) recognizes that CQA during field construction is imperative for successful completion of project work and long-term facility operation. This paper discusses the importance of CQA during FML installation and the practical aspects of implementing a successful CQA program. Standard methods used for FML evaluation, in both the field and laboratory, are discussed and specific aspects of seam testing and data evaluation are addressed. The general importance of comprehensive definition of geomembrane seam field failures is strongly emphasized so that an appropriate response to test failures can be recommended

    Air leakage control through the building envelope of wood framed houses is more important than ever. The leakage of air is controlled by the air barrier system. There are several new technologies to construct an air barrier system for the building envelope. These are the Poly Approach, the Air Drywall Approach and the EASE system. The development of these systems was undertaken primarily by the building community without significant research and development. The purpose of this study was to determine the actual performance of several different types of construction details for each of the different approaches. Each of these details was designed and constructed using one of the air barrier methods and tested in the laboratory. The test details included the sill plate, the partition wall, the stair stringer, the electrical outlets, the bathtub detail, the plumbing stack detail, the metal chimney detail, the bathroom fan detail and the EASE wall system.

    The inhalation of (222) Rn (radon) decay products is one of the most important reasons for lung cancer after smoking. Stony building materials are an important source of indoor radon. This article describes the determination of the exhalation rate of stony construction materials by the use of commercially available measuring devices in combination with VOC emission test chambers. Five materials - two types of clay brick, clinker brick, light-weight concrete brick, and honeycomb brick - generally used for wall constructions were used for the experiments. Their contribution to real room concentrations was estimated by applying room model parameters given in ISO 16000-9, RP 112, and AgBB. This knowledge can be relevant, if for instance indoor radon concentration is limited by law. The test set-up used here is well suited for application in test laboratories dealing with VOC emission testing. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2006-01-01

    Use of tire shreds in construction projects, such as highway embankments, is becoming an accepted way of beneficially recycling scrap tires. However, in the last decade there was a decline in the use of pure tire shreds as fill materials in embankment construction, as they are susceptible to fire hazards due to the development of exothermic reactions. Tire shred-sand mixtures, on the other hand, were found to be effective in inhibiting exothermic reactions. When compared with pure tire shreds, tire shred-sand mixtures are less compressible and have higher shear strength. However, the literature contains limited information on the use of tire shred-soil mixtures as a fill material. The objectives of this paper are to discuss and evaluate the feasibility of using tire shred-sand mixtures as a fill material in embankment construction. A test embankment constructed using a 50/50 mixture, by volume, of tire shreds and sand was instrumented and monitored to: (a) determine total and differential settlements; (b) evaluate the environmental impact of the embankment construction on the groundwater quality due to leaching of fill material; and (c) study the temperature variation inside the embankment. The findings in this research indicate that mixtures of tire shreds and sand are viable materials for embankment construction.

    To establish criterion-related construct validity and test-retest reliability for the Endotracheal Suction Assessment Tool© (ESAT©). Endotracheal tube suction performed in children can significantly affect clinical stability. Previously identified clinical indicators for endotracheal tube suction were used as criteria when designing the ESAT©. Content validity was reported previously. The final stages of psychometric testing are presented. Observational testing was used to measure construct validity and determine whether the ESAT© could guide "inexperienced" paediatric intensive care nurses' decision-making regarding endotracheal tube suction. Test-retest reliability of the ESAT© was performed at two time points. The researchers and paediatric intensive care nurse "experts" developed 10 hypothetical clinical scenarios with predetermined endotracheal tube suction outcomes. "Experienced" (n = 12) and "inexperienced" (n = 14) paediatric intensive care nurses were presented with the scenarios and the ESAT© guiding decision-making about whether to perform endotracheal tube suction for each scenario. Outcomes were compared with those predetermined by the "experts" (n = 9). Test-retest reliability of the ESAT© was measured at two consecutive time points (4 weeks apart) with "experienced" and "inexperienced" paediatric intensive care nurses using the same scenarios and tool to guide decision-making. No differences were observed between endotracheal tube suction decisions made by "experts" (n = 9), "inexperienced" (n = 14) and "experienced" (n = 12) nurses confirming the tool's construct validity. No differences were observed between groups for endotracheal tube suction decisions at T1 and T2. Criterion-related construct validity and test-retest reliability of the ESAT© were demonstrated. Further testing is recommended to confirm reliability in the clinical setting with the "inexperienced" nurse to guide decision-making related to endotracheal tube

    Full Text Available The selection of suitable procurement practice for construction projects is a very complex and demanding tasks for stakeholders in the construction industry. In spite of the overabundance of techniques and tools accessible to the stakeholders in selecting an appropriate procurement method, clients are faced with the decision as to which of the selection criteria can be adopted for a given construction project to achieve project goals and objectives. This paper focused on evaluating the existing procurement methods being practised in the Nigerian construction industry with a view to identifying and establishing the parameters for selection that will improve contract delivery systems. In this research, quantitative approach was used to collect data from 420 contractors, consultants and clients based in the Federal Capital Territory, Abuja where large numbers of building projects are being procured. The findings revealed six most commonly considered criteria and deduced that, the quality, cost and duration of the project determines the type of procurement method to adopt. It is therefore stated that in selecting any particular procurement method for building construction projects, the complexity of such project should be clearly defined and the other performance indicators be given adequate consideration for a successful project delivery that will enhance the achievement of the client’s goal.

    For the MedAustron facility under construction in Wiener Neustadt/Austria, two electrostatic septa are built in collaboration with CERN. These septa will be used for the multi-turn injection of protons and ions, as well as for the slow extraction from the synchrotron. The power supplies are designed to combine the required precision with the capability to cycle sufficiently fast to keep up with the machine cycle. The septa are being assembled at CERN. Initial tests have been done on the remote displacement system to validate its precision and communication protocol with the MedAustron control system. Subsequently the septa are tested for vacuum performance and then HV conditioned. The construction of the septa, the requirements of the power supplies and the high voltage circuit will be described. Results of the initial laboratory tests, prior to installation in the accelerator, will be given.

    1995-09-01

    This report is one in a series of PVUSA reports on PVUSA experiences and lessons learned at the demonstration sites in Davis and Kerman, California, and from participating utility host sites. During the course of approximately 7 years (1988--1994), 10 PV systems have been installed ranging from 20 kW to 500 kW. Six 20-kW emerging module technology arrays, five on universal project-provided structures and one turnkey concentrator, and four turnkey utility-scale systems (200 to 500 kW) were installed. PVUSA took a very proactive approach in the procurement of these systems. In the absence of established procurement documents, the project team developed a comprehensive set of technical and commercial documents. These have been updated with each successive procurement. Working closely with vendors after the award in a two-way exchange provided designs better suited for utility applications. This report discusses the PVUSA procurement process through testing and acceptance, and rating of PV turnkey systems. Special emphasis is placed on the acceptance testing and rating methodology which completes the procurement process by verifying that PV systems meet contract requirements. Lessons learned and recommendations are provided based on PVUSA experience.

    Inadequately adopted fundamental movement skills (FMS) in early childhood may have a negative impact on the motor performance in later life (Gallahue and Ozmun, 2005). The need for an efficient FMS testing in Physical Education was recognized. The aim of this paper was to construct and validate a new FMS test for 8 year old children. Ninety-five 8 year old children were used for the testing. A total of 24 new FMS tasks were constructed and only the best representatives of movement areas entered into the final test product - FMS-POLYGON. The ICC showed high values for all 24 tasks (0.83-0.97) and the factorial analysis revealed the best representatives of each movement area that entered the FMS-POLYGON: tossing and catching the volleyball against a wall, running across obstacles, carrying the medicine balls, and straight running. The ICC for the FMS-POLYGON showed a very high result (0.98) and, therefore, confirmed the test's intra-rater reliability. Concurrent validity was tested with the use of the "Test of Gross Motor Development" (TGMD-2). Correlation analysis between the newly constructed FMS-POLYGON and the TGMD-2 revealed the coefficient of -0.82 which indicates a high correlation. In conclusion, the new test for FMS assessment proved to be a reliable and valid instrument for 8 year old children. Application of this test in schools is justified and could play an important factor in physical education and sport practice. Key pointsAll 21 newly constructed tasks demonstrated high intra-rater reliability (0.83-0.97) in FMS assessment. High reliability was also noted in the FMS-POLYGON test (0.98).A high correlation was found between the FMS-POLYGON and TGMD-2 which is a confirmation of the new test's concurrent validity.The research resolved the problem of long and detailed FMS assessment by adding a new dimension using quick and effective norm-referenced approach but also covering all the most important movement areas.New and validated test can be of great use

    The 4-T, 6-m free bore CMS solenoid has been successfully tested, operated and mapped at CERN during the autumn of 2006; R&D studies started in 1993 and the construction proper in 1997. The main parameters of this 100 MUS$ project (including yoke) were then considered beyond what was thought possible, as the total stored magnetic energy reaches 2.6 GJ for a specific magnetic energy density exceeding 11 kJ/kg of cold mass. During this period, the international design and construction team had to make several important technical choices, in particular mechanical, to maximize the chances of reaching the nominal induction of 4 Tesla. The paper will review these choices in the light of what is presently known and examine if better solutions would be possible today for constructing a new large high-field thin solenoid for a future detector magnet.

    Energy Technology Data Exchange (ETDEWEB)

    Lang, Philipp-Michael

    2015-01-15

    The study of High Energy Density Matter (HEDM) in the laboratory makes great demands on the diagnostics because these states can usually only be created for a short time and usual diagnostic techniques with visible light or X-rays come to their limit because of the high density. The high energy proton radiography technique that was developed in the 1990s at the Los Alamos National Laboratory is a very promising possibility to overcome those limits so that one can measure the density of HEDM with high spatial and time resolution. For this purpose the proton microscope PRIOR (Proton Radiography for FAIR) was set up at GSI, which not only reproduces the image, but also magnifies it by a factor of 4.2 and thereby penetrates matter with a density up to 20 g/cm{sup 2}. Straightaway a spatial resolution of less than 30 μm and a time resolution on the nanosecond scale was achieved. This work describes details to the principle, design and construction of the proton microscope as well as first measurements and simulations of essential components like magnetic lenses, a collimator and a scintillator screen. For the latter one it was possible to show that plastic scintillators can be used as converter as an alternative to the slower but more radiation resistant crystals, so that it is possible to reach a time resolution of 10 ns. Moreover the characteristics were investigated for the system at the commissioning in April 2014. Also the changes in the magnetic field due to radiation damage were studied. Besides that an overview about future applications is given. First experiments with Warm Dense Matter created by using a Pulsed Power Setup have already been performed. Furthermore the promising concept of combining proton radiography with particle therapy has been investigated in context of the PaNTERA project. An outlook on the possibilities with future experiments at the FAIR accelerator facility is given as well. Because of higher beam intensity an energy one can expect even

  10. Effects of seasonal and well construction variables on soil vapor extraction pilot tests

    International Nuclear Information System (INIS)

    Campbell, R.; Hudon, N.; Bass, D.

    1995-01-01

    The selection and design of an effective soil vapor extraction system is dependent upon data generated from pilot testing. Therefore, it is critical to understand factors that may affect the testing prior to selecting or designing a system. In Sebago Lake Village, Maine, two adjacent gasoline stations experienced a release. Gasoline migrated through fine sand into the groundwater and discharged to a small stream. Soil vapor extraction was investigated as a remedial alternative to reduce volatile organic compounds in the unsaturated soil. Three soil vapor extraction pilot tests were performed at one of the sites and one test at the other site. The results of the testing varied. Data collected during a summer test indicated soil vapor extraction was less likely to work. The wells tested were installed using an excavator. An adequate surface seal was not present in any of the tested wells. An additional test was performed in the winter using wells installed by a drill rig. Winter test results indicated that soil vapor extraction could be effective. Another test was performed after a horizontal soil vapor extraction system with a surface seal was installed. The results of this testing indicated that soil vapor extraction was more effective than predicted by the earlier tests. Tests performed on the other property indicated that the horizontal wells were more effective than the vertical wells. Testing results were affected by the well installation method, well construction, proximity to manmade structures, and the season in which testing was performed. Understanding factors that affect the testing is critical in selecting and designing the system

    The Free and Cued Selective Reminding Test (FCSRT) is the memory test recommended by the International Working Group on Alzheimer's disease (AD) for the detection of amnestic syndrome of the medial temporal type in prodromal AD. Assessing the construct validity and internal consistency of the Italian version of the FCSRT is thus crucial. The FCSRT was administered to 338 community-dwelling participants with memory complaints (57% females, age 74.5 ± 7.7 years), including 34 with AD, 203 with Mild Cognitive Impairment, and 101 with Subjective Memory Impairment. Internal Consistency was estimated using Cronbach's alpha coefficient. To assess convergent validity, five FCSRT scores (Immediate Free Recall, Immediate Total Recall, Delayed Free Recall, Delayed Total Recall, and Index of Sensitivity of Cueing) were correlated with three well-validated memory tests: Story Recall, Rey Auditory Verbal Learning test, and Rey Complex Figure (RCF) recall (partial correlation analysis). To assess divergent validity, a principal component analysis (an exploratory factor analysis) was performed including, in addition to the above-mentioned memory tasks, the following tests: Word Fluencies, RCF copy, Clock Drawing Test, Trail Making Test, Frontal Assessment Battery, Raven Coloured Progressive Matrices, and Stroop Colour-Word Test. Cronbach's alpha coefficients for immediate recalls (IFR and ITR) and delayed recalls (DFR and DTR) were, respectively, .84 and .81. All FCSRT scores were highly correlated with those of the three well-validated memory tests. The factor analysis showed that the FCSRT does not load on the factors saturated by non-memory tests. These findings indicate that the FCSRT has a good internal consistency and has an excellent construct validity as an episodic memory measure. © 2015 The British Psychological Society.

    2016-06-01

    Full Text Available This paper aims to review the use of various construction procurement systems and present the development of Relationship-Based Procurement (RBP Methods currently in use within the Australian construction industry. Therefore, this paper provides the historical development of procurement briefly and then focuses on the adoption of Relationship-Based Procurement (RBP approaches in the Australian construction industry to investigate the future direction of the collaborative project procurement arrangements. Semi-structured interviews with high-level managers in the Australian state government organizations have been conducted to answer the research question. A discussion has been presented about the potential future tendency of the industry in adopting a RBP. The findings suggest that even though relationship based procurement systems offer significant benefits; they are not popular among the public sector decision makers because of inability to demonstrate Value for Money (VfM propositions for public projects. Other reasons which may cause a move away from using RBPs in the future include the need for managers to fully engage throughout the project, and the lack of collaborative environment within the construction industry in general.

    Energy Technology Data Exchange (ETDEWEB)

    1993-03-31

    Air leakage control through the building envelope of wood framed houses is more important than ever. This is because owners expect better temperature control, higher indoor humidity in winter, low energy consumption and building durability. The leakage of air is controlled by the air barrier system. There are several new technologies to construct an air barrier system for the building envelope. These are the Poly Approach, the Air Drywall Approach (ADA) and the EASE system. The development of these systems was undertaken primarily by the building community without significant research and development. While it is believed that these methods improve airtightness it is not known if the improvement is marginal or significant. A study was conducted to determine actual performace of several different types of construction details for each of the different approaches. Each of these details was designed and constructed using one of the air barrier methods and tested in the laboratory. The test details included sill plate, the partition wall, the stair stringer, the electrical outlets, the bathtub detail, the plumbing stack detail, the metal chimney detail, the bathroom fan detail and the EASE wall system. The test results revealed that the Poly, ADA and EASE approaches reduce air leakage by a factor of six, if applied with a modest degree of workmanship. Further, certain Poly details are to be reconsidered because they lack adequate support against design wind load pressures. 37 figs., 12 tabs.

    The US Department of Energy (USDOE) is planning to construct and operate a structure, designated the Nuclear Test Technology Complex (NTTC), on a site located west of and adjacent to the Lawrence Livermore National Laboratory. The NTTC is designed to house 350 nuclear test program personnel, and will accommodate the needs of the entire staff of the continuing Nuclear Test Program (NTP). The project has three phases: land acquisition, facility construction and facility operation. The purpose of this environmental assessment report is to describe the activities associated with the three phases of the NTTC project and to evaluate potential environmental disruptions. The project site is located in a rural area of southeastern Alameda County, California, where the primary land use is agriculture; however, the County has zoned the area for industrial development. The environmental impacts of the project include surface disturbance, high noise levels, possible increases in site erosion, and decreased air quality. These impacts will occur primarily during the construction phase of the NTTC project and can be mitigated in part by measures proposed in this report.

Scoring for each skill is based on the number of performance criteria successfully demonstrated. An overall resistance training skill quotient (RTSQ) is created by adding participants' scores for the 6 skills. Participants (44 boys and 19 girls, mean age = 14.5 ± 1.2 years) completed the RTSB on 2 occasions separated by 7 days. Participants also completed the following fitness tests, which were used to create a muscular fitness score (MFS): handgrip strength, timed push-up, and standing long jump tests. Intraclass correlation (ICC), paired samples t-tests, and typical error were used to assess test-retest reliability. To assess construct validity, gender and RTSQ were entered into a regression model predicting MFS. The rank order repeatability of the RTSQ was high (ICC = 0.88). The model explained 39% of the variance in MFS (p ≤ 0.001) and RTSQ (r = 0.40, p ≤ 0.001) was a significant predictor. This study has demonstrated the construct validity and test-retest reliability of the RTSB in a sample of adolescents. The RTSB can reliably rank participants in regards to their resistance training competency and has the necessary sensitivity to detect small changes in resistance training skill proficiency.

    This paper addresses procurement planning in oil refining, which has until now only had limited attention in the literature. We introduce a mixed integer nonlinear programming (MINLP) model and develop a novel two-stage solution approach, which aims at computational efficiency while addressing...... parameters than in previous literature. The developed approach is tested using historical data from Statoil A/S as well as through a comprehensive numerical analysis. The approach generates a feasible procurement plan within acceptable computation time, is able to quickly adjust an existing plan to take...

  1. Construction and performance tests of a secondary hydrogen gas cooling system

    International Nuclear Information System (INIS)

    Sanokawa, K.; Hishida, M.

    1980-01-01

    With the aim of a multi-purpose use of nuclear energy, such as direct steel-making, an experimental multi-purpose high-temperature gas-cooled reactor (VHTR) is now being developed by the Japan Atomic Energy Research Institute (JAERI). In order to simulate a heat exchanging system between the primary helium gas loop and the secondary reducing gas system of the VHTR, a hydrogen gas loop as a secondary cooling system of the existing helium gas loop was completed in 1977, and was successfully operated for over 2000 hours. The objectives of constructing the H 2 secondary loop were: (1) To get basic knowledge for designing, constructing and operating a high-temperature and high-pressure gas facility; (2) To perform the following tests: (a) hydrogen permeation at the He/H 2 heat exchanger (the surfaces of the heat exchanger tubes are coated by calorizing to reduce hydrogen permeation), (b) thermal performance tests of the He/H 2 heat exchanger and the H 2 /H 2 regenerative heat exchanger, (c) performance test of internal insulation, and (d) performance tests of the components such as a H 2 gas heater and gas purifiers. These tests were carried out at He gas temperature of approximately 1000 0 C, H 2 gas temperature of approximately 900 0 C and gas pressures of approximately 40 kg/cm 2 G, which are almost the same as the operating conditions of the VHTR

    1992-01-01

    A full-scale model of the 1.25 m long MDSBV (Magnet Decapole Sextupole Bending Vertical) correction magnet for the Large Hadron Collider (LHC) has been constructed and is currently being tested. The model contains the desired dipole and sextupole but not the decapole which was decided upon later. The magnet was built in a very compact way by placing the dipole coil around the sextupole coil. The two coils were vacuum impregnated and prestressed by shrink-fitted aluminum rings. The design took into account the high positional accuracy requirements for the coils and incorporated manufacturing techniques which are compatible with mass production methods, as approximately 800 of these magnets will be required for the LHC. The model is being tested in liquid helium at the temperature of 4.2 K and will be tested later at 2.0 K. The paper describes the construction, the experience gained during assembly, the test conditions and gives the first test-results

  3. Design and construction of a block test in closely jointed rock

    Black, M.T.; Cramer, M.L.

    1983-06-01

    The Basalt Waste Isolation Project developed a large-scale block test to investigate the in-situ deformational response of a basalt rock mass. The test was designed and installed into the vertical rib (wall) of a tunnel to examine the response of basalt both in a parallel and perpendicular mode to the basalt columns. The salient challenge confronting the design and development of the test was a lack of documented experience for testing into a vertical wall. Information was available for testing in a horizontal surface. The major tasks involved in the implementation of this test included flat-jack slot drilling, instrumentation hole drilling, cable anchor hole drilling, flat-jack installation, monitoring instrumentation installation, and cable anchor installation. Drilling in the closely jointed and fractured rock mass required extreme care to prevent unraveling of the columnar structure and to minimize the disturbance of the section to be tested. The adaptation of a high-strength cable anchor system to the space limitations of the test configuration and the design and implementation of an optical deformation monitoring device capable of achieving a measurement precision of 30 μm required equal innovation. Construction of the test facility was successfully completed on schedule in approx. 25 wk

  4. Test methods for selection of materials of construction for high-level radioactive waste vitrification. Revision

    Bickford, D.F.; Corbett, R.A.; Morrison, W.S.

    1986-01-01

    Candidate materials of construction were evaluated for a facility at the Department of Energy's Savannah River Plant to vitrify high-level radioactive waste. Limited operating experience was available under the corrosive conditions of the complex vitrification process. The objective of the testing program was to provide a high degree of assurance that equipment will meet or exceed design lifetimes. To meet this objective in reasonable time and minimum cost, a program was designed consisting of a combination of coupon immersion and electrochemical laboratory tests and pilot-scale tests. Stainless steels and nickel-based alloys were tested. Alloys that were most resistant to general and local attack contained nickel, molybdenum (>9%), and chromium (where Cr + Mo > 30%). Alloy C-276 was selected as the reference material for process equipment. Stellite 6 was selected for abrasive service in the presence of formic acid. Alloy 690 and ALLCORR were selected for specific applications

  5. Design, construction and testing of a self-powered neutron detector

    Correa, R.F.

    1987-01-01

    The design, construction and testing of a self-powered neutron detector (SPN) and associated electronics are described. Several tests were performed giving information about dielectrical properties of detector and cable, gamma spectra induced in the detector through reactor irradiation, detector response as a function of neutron flux, current stability and reproductibility with the neutron flux. The gamma and neutron sensitivities were also evaluated, by means of thermoluminescent dosimeters and gold foils as references. The test results are presented and show that the detector response is reliable. The gamma and neutron sensitivities are in agreement with those found in the available literature. Nevertheless, a ceramic insulated cable should be employed for permanent use in a reactor. The tests were performed in a 100 KW TRIGA Mark I reactor at the Centro de Desenvolvimento da Tecnologia Nuclear of NUCLEBRAS, in Belo Horizonte, Brazil. (author) [pt

    1981-01-01

    The Spent Fuel Test-Climax (SFT-C) is a test of retrievable deep geologic storage of commercially generated spent nuclear reactor fuel in granitic rock. Eleven spent fuel assemblies, together with six electrical simulators and 20 guard heaters, are emplaced 420 m below the surface in the Climax granite at the US Department of Energy Nevada Test Site. On June 2, 1978 LLNL secured funding for the SFT-C, and completed spent fuel emplacement May 28, 1980. This report documents a series of thermal calculations that were performed in support of the SFT-C. Early calculations employed analytical solutions to address such design and construction issues as drift layout and emplacement hole spacings. Operational aspects of the test required more detailed numerical solutions dealing with ventilation and guard-heater power levels. The final set of calculations presented here provides temperature histories throughout the test facility for evaluation of the response of the SFT-C and for comparison of calculations with acquired data. This final set of calculations employs the as-built test geometry and best-available material properties

    This thesis questions the prospects for the World Trade Organisation, Agreement on Government Procurement. This is the most important international agreement seeking to promote cross-border trade in hitherto closed national procurement markets. For the above threshold goods, services and construction services contracts which it covers, the Agreement's principal objective is to require the non-discriminatory treatment of foreign suppliers. It is because of this general insistence on non-discri...

    We measure the impact of municipal policies requiring governments to construct green buildings on private-sector adoption of the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) standard. Using matching methods, panel data, and instrumental variables, we find that government procurement rules produce spillover effects that stimulate both private-sector adoption of the LEED standard and supplier investments in green building expertise. Our findings suggest tha...

  9. Design, construction and testing of replacement nuclear coolant pump stators to meet today's equipment reliability expectations

    International Nuclear Information System (INIS)

    Fostier, L.; Howell, D.

    2005-01-01

    The reliability expectations of equipment and components in today's nuclear power plant are much greater than three or more decades ago when nuclear plants were first constructed due to economic impact of a failure. Very few components in a pressurized water reactor plant can have as much impact of the plants capacity factor as a catastrophic failure of a reactor coolant pump winding. This paper describes the maintenance approach taken by one North American utility in attempt to preclude such failures. The paper will discuss the challenges of the reactor coolant pump application and the enhancements made in the winding design and construction by the supplier to address failure mechanisms so as to better meet present reliability expectations in accordance with dedicated specifications. The paper will also present the in-process and final testing requirements and limits imposed in an attempt to ensure quality of the machine windings, along with selected test results from the stators that have been designed and constructed to these specifications to date.

    1998-01-01

    The Murmansk Initiative - RF was instigated to address Russia's ability to meet the London Convention prohibiting ocean dumping of radioactive waste. The Initiative, under a trilateral agreement, will upgrade an existing low-level liquid radioactive waste treatment facility, increasing capacity from 1,200 m 3 /year to 5,000 m 3 /year, and expand the capability to treat liquids containing salt (up to 10 g/L). The three parties to the agreement, the Russian Federation, Norway, and the US, have split the costs for the project. All construction has been provided by Russia. Construction of mechanical systems (piping and valves, pumps, sorbent columns, settling tanks, surge tanks) is nearly complete, with instrumentation and control (I+C) systems the last to be installed. Delays to the I+C installation have occurred because changes in system specifications required some additional US-supplied computer control equipment to be purchased, and clearance through customs (both US and Russian) has been slow. Start-up testing has been limited to testing of some isolated sub-systems because of the delays in I+C installation. Final construction activities are also hampered by the current state of the Russian economy. The specific impact has been completion of the cementation unit, which was not funded under the trilateral agreement (but funded by the Russian government). Russian regulatory authorities have stated that final licensing for expanded capacity (5,000 m 3 /year) will not be given until the cementation unit is on-line

    Currently, the Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is under construction. One experiment at GSI and FAIR is called Reactions with Relativistic Radioactive Beams (R{sup 3}B). A key component of the R{sup 3}B is the CALorimeter for In Flight detection of γ-rays and light charged pArticles (CALIFA), which will surround the R{sup 3}B target chamber and will be capable of the detection of γ-rays in a wide energy range from 100 keV to 30 MeV as well as of light charged particles. CALIFA is built out of two parts, the so called CALIFA barrel and CALIFA endcap. The barrel consists of 1952 CsI(Tl) detector crystals which have to fulfill several specifications. One of these specifications is the uniformity of the light output. Depending on the location of the deposited energy, the crystal's light output varies due to optical focusing effects. This behavior can be manipulated by lapping the crystal's surface. The aim of this work is the development of a test stand which will check if the crystals match the requirements according to the light output uniformity. Because of the large number of crystals needed to be tested, the stand automates the test procedure, which guarantees comparable test measurement for all crystals. The development and construction of this stand is reported.

    In view of unavailability in Poland of the standardized methods to measure PIQ, the aim of the work was to develop a Polish test to assess the premorbid level of intelligence - PART(Polish AdultReading Test) and to measureits psychometric properties, such as validity, reliability as well as standardization in the group of schizophrenia patients. The principles of PART construction were based on the idea of popular worldwide National Adult Reading Test by Hazel Nelson. The research comprised a group of 122 subjects (65 schizophrenia patients and 57 healthy people), aged 18-60 years, matched for age and gender. PART appears to be a method with high internal consistency and reliability measured by test-retest, inter-rater reliability, and the method with acceptable diagnostic and prognostic validity. The standardized procedures of PART have been investigated and described. Considering the psychometric values of PART and a short time of its performance, the test may be a useful diagnostic instrument in the assessment of premorbid level of intelligence in a group of schizophrenic patients.

    Three studies assessed the construct of pathological video game use and tested its predictive validity. Replicating previous research, Study 1 produced evidence of convergent validity in 8th and 9th graders (N = 607) classified as pathological gamers. Study 2 replicated and extended the findings of Study 1 with college undergraduates (N = 504). Predictive validity was established in Study 3 by measuring cue reactivity to video games in college undergraduates (N = 254), such that pathological gamers were more emotionally reactive to and provided higher subjective appraisals of video games than non-pathological gamers and non-gamers. The three studies converged to show that pathological video game use seems similar to other addictions in its patterns of correlations with other constructs. Conceptual and definitional aspects of Internet Gaming Disorder are discussed. PMID:26694472

    The Department of Energy has constructed the Waste Isolation Pilot Plant (WIPP) to develop the technology for the disposal of radioactive waste from defense programs. Sandia National Laboratories has the responsibility for experimental activities at the WIPP and has emplaced several large-scale Thermal/Structural Interactions (TSI) in situ tests to validate techniques used to predict repository performance. The construction of the tests relied heavily on earlier excavations at the WIPP site to provide a basis for selecting excavation, surveying, and instrumentation methods, and achievable construction tolerances. The tests were constructed within close tolerances to provide consistent room dimensions and accurate placement of gages. This accuracy has contributed to the high quality of data generated which in turn has facilitated the comparison of test results to numerical predictions. The purpose of this report is to detail the construction activities of the TSI tests.

    Two extraction kicker magnet assemblies that contain seven individual pulsed magnet modules each will kick the proton beam vertically out of the SNS accumulator ring into the aperture of the extraction Lambertson septum magnet. The proton beam then travels to the 1.4 MW SNS target assembly. The 14 kicker magnets and major components of the kicker assembly have been fabricated in BNL. The inner surfaces of the kicker magnets were coated with TiN to reduce the secondary electron yield. All 14 PFN power supplies have been built, tested and delivered to OWL. Before final installation, a partial assembly of the kicker system with three kicker magnets was assembled to test the functions of each critical component in the system. In this paper we report the progress of the construction of the kicker components, the TIN coating of the magnets, the installation procedure of the magnets and the full power test of the kicker with the PFN power supply

    Dyslexia is a specific language-based disorder of constitutional origin, characterized by difficulties in phonological processing. The Arabic language differs in many aspects from foreign languages and the few previously designed Arabic tests for assessment of dyslexia did not pay attention to phonological awareness problems. This necessitates the design of an Arabic test which could properly assign specific difficulties among Arabic reading dyslexic children, including phonological awareness as a major contributing factor for dyslexia. The study was carried out in Assiut City, Egypt, during the period from September 1999 to the end of January 2001. The newly designed Arabic Reading Test (ART) in this work passed through many stages. Firstly, test construction by 11 Arabic teachers (specific judges). Secondly it was applied, in a pilot study, to 50 normal students (9-10 years old) to ascertain clarity of the test. Then test standardization was proven through application on a second sample (n=252 students), and third sample (n=58 dyslexics). The reliability of the ART was proven by the test-retest method (r=0.913, pdyslexia among Arabic reading children. It has great value in predicting dyslexia even among preschool age Arabic speaking children, through assessment of their phonological awareness skills, and thus, remediation programs can be properly and early directed.

    Cartilage tissue engineering is emerging as a promising treatment for osteoarthritis, and the field has progressed toward utilizing large animal models for proof of concept and preclinical studies. Mechanical testing of the regenerative tissue is an essential outcome for functional evaluation. However, testing modalities and constitutive frameworks used to evaluate in vitro grown samples differ substantially from those used to evaluate in vivo derived samples. To address this, we developed finite element (FE) models (using FEBio) of unconfined compression and indentation testing, modalities commonly used for such samples. We determined the model sensitivity to tissue radius and subchondral bone modulus, as well as its ability to estimate material parameters using the built-in parameter optimization tool in FEBio. We then sequentially tested agarose gels of 4%, 6%, 8%, and 10% weight/weight using a custom indentation platform, followed by unconfined compression. Similarly, we evaluated the ability of the model to generate material parameters for living constructs by evaluating engineered cartilage. Juvenile bovine mesenchymal stem cells were seeded (2 × 10 7 cells/mL) in 1% weight/volume hyaluronic acid hydrogels and cultured in a chondrogenic medium for 3, 6, and 9 weeks. Samples were planed and tested sequentially in indentation and unconfined compression. The model successfully completed parameter optimization routines for each testing modality for both acellular and cell-based constructs. Traditional outcome measures and the FE-derived outcomes showed significant changes in material properties during the maturation of engineered cartilage tissue, capturing dynamic changes in functional tissue mechanics. These outcomes were significantly correlated with one another, establishing this FE modeling approach as a singular method for the evaluation of functional engineered and native tissue regeneration, both in vitro and in vivo.

    An experimental multi-purpose High-Temperature Gas Cooled Reactor (VHTR) which is supposed to be used for a direct steel-making is now being developed in JAeRI. In order to simulate the heat exchanging system between the primary helium gas and the secondary reducing gas system of VHTR, a hydrogen gas loop was constructed as a secondary cooling system of the helium gas loop. The maximum temperature and the maximum pressure of the hydrogen gas are 900 degrees C and 42 kg/cm 2 x G respectively. The construction of the hydrogen gas loop was completed in January, 1977, and was successfully operated for 1.000 h. Various performance tests, such as the hydrogen permeation test of a He/H2 heat exchanger and the thermal performance test of heat exchangers, were made. Especially, it was proved that hydrogen permeation rate through the heat exchanger was reduced to 1/30 to approximately 1/50 by a method of calorized coating, and the coating was stable during 1.000 h's operation. It was also stable against the temperature changes. This report describes the outline of the facility and performance of the components. (orig.) [de

    The gamma-scanning method is an important tool for the measurement of burnup of nuclear reactor fuel. The adequate knowledge of burnup allows for a better inventory of 'sensitive' fissile materials, better fuel management and provides insight on fuel behaviour and safety margins. This paper is related to the description, construction and operation of a first gamma scanning device, tested by irradiation of prototype PWR fuel pins, 14 cm long, in a Triga Mark-I reactor at very low power. Despite the limitations imposed by the low burnup, the experiment permitted a good checking of the main physical concepts and devices involved in the method. (Author) [pt

    The Phase II upgrade to the LHC collimation system calls for complementing the 30 high robust Phase I graphite secondary collimators with 30 high Z Phase II collimators. The Phase II collimators must be robust in various operating conditions and accident scenarios. This paper reports on the final construction and testing of the prototype collimator to be installed in the SPS (Super Proton Synchrotron) at CERN. Bench-top measurements will demonstrate that the device is fully operational and has the mechanical and vacuum characteristics acceptable for installation in the SPS.

    MIT and PPPL have joined together to fabricate a high-power lower hybrid current drive (LHCD) system for supporting steady-state AT regime research on Alcator C-Mod. The goal of the first step of this project is to provide 1.5 MW of 4.6 GHz rf [radio frequency] power to the plasma with a compact launcher which has excellent spectral selectivity and fits into a single C-Mod port. Some of the important design, construction, calibration and testing considerations for the launcher leading up to its installation on C-Mod are presented here

  9. Risk, innovation, electricity infrastructure and construction cost overruns: Testing six hypotheses

    International Nuclear Information System (INIS)

    Sovacool, Benjamin K.; Gilbert, Alex; Nugent, Daniel

    2014-01-01

    This study investigates the frequency and magnitude of cost and time overruns occurring during the construction of 401 electricity projects built between 1936 and 2014 in 57 countries. In aggregate, these projects required approximately $820 billion in investment, and amounted to 325,515 MW of installed capacity and 8495 km of transmission lines. We use this sample of projects to test six hypotheses about construction cost overruns related to (1) diseconomies of scale, (2) project delays, (3) technological learning, (4) regulation and markets, (5) decentralization and modularity, and (6) normalization of results to scale. We find that nuclear reactors are the riskiest technology in terms of mean cost escalation as a percentage of budget and frequency; that hydroelectric dams stand apart for their mean cost escalation in total dollars; that many of the hypotheses grounded in the literature appear wrong; and that financing, partnerships, modularity, and accountability may have more to do with overruns than technology. - Highlights: • Many hypotheses about construction overruns grounded in the literature appear wrong. • Nuclear reactors are the most prone to cost overruns as a percentage of budget and frequency. • Hydroelectric dams stand apart for their mean cost escalation in total dollars. • Solar and wind energy systems are least at risk to cost overruns

  11. Construction and testing of a transportable solar adsorption refrigerator; Construction et test d'un refrigerateur solaire a adsorption transportable

    Energy Technology Data Exchange (ETDEWEB)

    Mayor, J.; Dind, P.

    2002-07-01

    The report describes the development of an autonomous solar adsorption refrigerator characterized by its compactness and transportability. The refrigerator utilizes water as the working fluid and silicagel as the adsorbent and operates discontinuously over the day/night cycle. For a cooling volume of about 100 liters a collector-adsorber surface of 1 m{sup 2} is required and the total mass of the system amounts to about 150 kg. In order to keep its mass as low as possible the apparatus has been built with light weight materials. The cold-storage room has been insulated with a high-performance insulation material, thus minimizing thermal losses without excessively reducing the cooled volume. A new automatic valve system has been developed making superfluous any manual manipulation during normal operation. The dimensioning of the cooling system allows to cool the equivalent of 2.5 to 3.7 kg of water by 30 K daily in a climate of the Sahelien type. The cooling energy is stored in the form of ice in the evaporator and allows to bridge a period of three overcast-sky days. The construction of the solar refrigerator was made in cooperation with small regional enterprises and workshops. The cooperation with a non governmental organization allowed to test the system from May to September 2002 in a Subsaharian region of Africa where an equivalent model had been built using locally available materials. Likewise, a market study has been made in Burkina Faso in order to analyze the potential of solar adsorption refrigerators in this region. The result of the study suggests that the opening of a production workshop for such refrigerators in Burkina Faso is promising.

Controlling for several covariates, we always find that centralized and hybrid procurers pay lower prices as...

  13. Procurement Options for New Renewable Electricity Supply

    Energy Technology Data Exchange (ETDEWEB)

    Kreycik, C. E.; Couture, T. D.; Cory, K. S.

    2011-12-01

    State renewable portfolio standard (RPS) policies require utilities and load-serving entities (LSEs) to procure renewable energy generation. Utility procurement options may be a function of state policy and regulatory preferences, and in some cases, may be dictated by legislative authority. Utilities and LSEs commonly use competitive solicitations or bilateral contracting to procure renewable energy supply to meet RPS mandates. However, policymakers and regulators in several states are beginning to explore the use of alternatives, namely feed-in tariffs (FITs) and auctions to procure renewable energy supply. This report evaluates four procurement strategies (competitive solicitations, bilateral contracting, FITs, and auctions) against four main criteria: (1) pricing; (2) complexity and efficiency of the procurement process; (3) impacts on developers access to markets; and (4) ability to complement utility decision-making processes. These criteria were chosen because they take into account the perspective of each group of stakeholders: ratepayers, regulators, utilities, investors, and developers.

  14. Ethics and regulation in organ procurement research.

    Science.gov (United States)

    Ackerman, Terrence F; Winsett, Rebecca P

    2002-12-01

    This article explores the role of ethics and regulation in human research conducted by organ procurement agencies; basic ethical principles for human research are outlined. Organ procurement agencies are not required to observe federal regulations; however, voluntary adherence will ensure that procurement research is conducted according to current standards of ethical practice. Although most organ procurement research will qualify for exempt status, this determination should be made by an institutional review board. Even if studies qualify for exempt status, there is a moral presumption that informed consent should be sought, unless certain narrow conditions for waiver of consent are satisfied. Finally, when future research utilizing organ procurement records is anticipated, procurement coordinators should provide sufficiently detailed information to families about such plans to permit their advance informed consent to research activities.

  15. Application of acoustical holography for construction shadow images in ultrasonic testing

    International Nuclear Information System (INIS)

    Kutzner, J.; Zimpfer, J.

    1977-01-01

    The full-scale, three-dimensional presentation of material defects by means of acoustical holography is limited on the one hand by an insufficient resolving power in depth of the procedure and, on the other hand, by the fact that the defects of the material to be examined often reflect mirror-like. Examined is the possible range of reducing these limitations by means of constructing shadow images of defects in ultrasonic testing without - as it is usually done - reconstructing the sonic field reflected by the flow but reconstructing the sonic field diffracted at the flow by means of acoustical holography. It has been shown that acoustical holography, during which the amplitude information is always analyzed as well as - on principle - the phase information, improves the efficiency of ultrasonic testing to a large extent.

    2006-01-01

    We are reporting about a scintillating fibre tracking detector which is proposed for the precise determination of the absolute luminosity of the CERN LHC at interaction point 1 where the ATLAS experiment is located. The detector needs to track protons elastically scattered under $\\mu$rad angles in direct vicinity to the LHC beam. It is based on square shaped scintillating plastic fibres read out by multi-anode photomultiplier tubes and is housed in Roman Pots. We describe the design and construction of prototype detectors and the results of a beam test experiment at DESY. The excellent detector performance established in this test validates the detector design and supports the feasibility of the proposed challenging method of luminosity measurement.

    1991-01-01

    Contractors under the U.S. Department of Energy management have implemented a comprehensive approach to the management of design and construction of the complex facility modifications at the SP-100 Ground Engineering System Test Site on the Hanford Reservation. The SP-100 Test Site employs a multi-organizational integrated management approach with clearly defined responsibilities to assure success. This approach allows for thorough planning and analysis before the project kick off, thus minimizing the number and magnitude of problems which arise during the course of the project. When combined with a comprehensive cost and schedule/project management reporting system the problems which do occur are recognized early enough to assure timely intervention and resolution

    A novel hadron calorimeter is being developed for future lepton colliding beam detectors. The calorimeter is optimized for the application of Particle Flow Algorithms (PFAs) to the measurement of hadronic jets and features a very finely segmented readout with 1 x 1 cm2 cells. The active media of the calorimeter are Resistive Plate Chambers (RPCs) with a digital, i.e. one-bit, readout. To first order the energy of incident particles in this calorimeter is reconstructed as being proportional to the number of pads with a signal over a given threshold. A large-scale prototype calorimeter with approximately 500,000 readout channels has been built and underwent extensive testing in the Fermilab and CERN test beams. This paper reports on the design, construction, and commissioning of the electronic readout system of this prototype calorimeter. The system is based on the DCAL front-end chip and a VME-based back-end.

    1995-01-01

    In situ toxicity tests were designed for Ceriodaphnia dubia and Chironomus tentans as part of a larger study designed to assess the effectiveness of constructed wetlands for the treatment of wastewater produced by oil production at Suncor OSG. The artificial wetlands were 50m long by 3m wide, with three replicates of the control and the treatment. Each wetland had four sample sites equidistant along its length, creating a gradient of treatment from site A being the most toxic to site D being the least toxic. Each test was conducted twice during the summer of 1994. Both the Ceriodaphnia and Chironomus test cages were a flow through design to allow for maximal exposure to the water within the wetlands. Mortality and reproduction were used as endpoints for Ceriodaphnia, whereas mortality and growth were used as endpoints for the Chironomus test. Test durations were fifteen and ten days respectively. Chironomus had very high mortality along the entire wetlands whereas Ceriodaphnia survival and fecundity increased along the length of the treatment wetlands. Both organisms had low mortality and high growth/fecundity in the control wetlands

  1. Predicting maintenance of attendance at walking groups: testing constructs from three leading maintenance theories.

    2014-07-01

    Little is known about the processes and factors that account for maintenance, with several theories existing that have not been subject to many empirical tests. The aim of this study was to test how well theoretical constructs derived from the Health Action Process Approach, Rothman's theory of maintenance, and Verplanken's approach to habitual behavior predicted maintenance of attendance at walking groups. 114 participants, who had already attended walking groups in the community for at least 3 months, completed a questionnaire assessing theoretical constructs regarding maintenance. An objective assessment of attendance over the subsequent 3 months was gained. Multilevel modeling was used to predict maintenance, controlling for clustering within walking groups. Recovery self-efficacy predicted maintenance, even after accounting for clustering. Satisfaction with social outcomes, satisfaction with health outcomes, and overall satisfaction predicted maintenance, but only satisfaction with health outcomes significantly predicted maintenance after accounting for clustering. Self-reported habitual behavior did not predict maintenance despite mean previous attendance being 20.7 months. Recovery self-efficacy, and satisfaction with health outcomes of walking group attendance appeared to be important for objectively measured maintenance, whereas self-reported habit appeared not to be important for maintenance at walking groups. The findings suggest that there is a need for intervention studies to boost recovery self-efficacy and satisfaction with outcomes of walking group attendance, to assess impact on maintenance.

  2. CMHC [Canadian Mortgage and Housing Corporation] research project: Testing of air barriers construction details

    Energy Technology Data Exchange (ETDEWEB)

    1991-08-26

    The airtightness of building envelopes is important in controlling comfort and energy usage in houses. Leakage generally occurs through construction details, where there are joints or connections between materials, or where there are penetrations for services or other components. A study was conducted to quantify the air leakage characteristics of three such details in wood-frame walls: the header joist, the electric outlets, and the window opening detail. Three construction methods employed to achieve airtightness were evaluated: the sealed internal membrane approach (POLY); the external air barrier approach using a continuous vapour permeable membrane sandwiched between two layers of wall sheathing(EASE); and the airtight drywall approach (ADA). Test panels containing the details were subjected to air leakage testing at pressure differentials from 50 to 1,000 pascals. Measurements of air flow were made and evidence of failure of the barrier due to pressure loading was noted. Leakage rates for the header detail with the POLY, EASE and ADA panels were 24%, 18% and 10% respectively of that for the reference panel. For the electrical outlet joint, leakage rates for POLY and EASE panels were 24% and 36%, while the ADA panel had higher leakage rates than the traditional panel. For the window detail, leakage rates were lowest for the ADA panel and similar for the POLY and EASE panels; all were less than 15% that of traditional panels. 48 figs., 2 tabs.

    The design considerations, construction techniques, prototype tests and performance characteristics of a pressurized drift chamber used in the MAC detector at PEP are described. The chamber consists of 324 aluminized mylar tubes of 6.9 mm diameter with wall thickness of 100 μm. With appropriate shielding it operates successfully at 4.6 cm from the beam line. It was simple to construct and was configured to permit any malfunctioning tubes to be remotely disconnected without affecting operation. The chamber operated without problems for two years in the PEP environmental with a gas mixture of 49.5% argon, 49.5% CO 2 , 1% CH 4 , at 4 atm absolute pressure. The mean spatial resolution averaged over all tubes was 45 μm. The time to distance relation for this gas mixture, along with the geometric positioning of individual wires relative to the central tracking chamber, was obtained with data from Bhabha scattering events. We also describe resolution studies performed with a prototype chamber in a SLAC test beam. A wide range of gases, gas pressures, and electronic parameters were explored. These studies proved that resolutions in the 10-50 μm range were possible. Our experience demonstrates that chambers of this type provide high precision tracking and are particularly suited for operation in regions with difficult physical access and/or high ambient radiation levels.

The purpose of this small scale facility is to simulate lead coolant fast reactor (LFR) coolant flow in an open lattice geometry core using seven electrical rods and liquid lead or lead-bismuth eutectic. Based on review of current world lead or lead-bismuth test facilities and research need listed in the Generation IV Roadmap, five broad areas of requirements of basis are identified: Develop and Demonstrate Prototype Lead/Lead-Bismuth Liquid Metal Flow Loop Develop and Demonstrate Feasibility of Submerged Heat Exchanger Develop and Demonstrate Open-lattice Flow in Electrically Heated Core Develop and Demonstrate Chemistry Control Demonstrate Safe Operation and Provision for Future Testing. These five broad areas are divided into twenty-one (21) specific requirements ranging from coolant temperature to design lifetime. An overview of project engineering requirements, design requirements, QA and environmental requirements are also presented. The purpose of this T and FRs is to focus the lead fast reactor community domestically on the requirements for the next unique state of the art test facility. The facility thermal hydraulic design is based on the maximum simulated core power using seven electrical heater rods of 420 kW; average linear heat generation rate of 300 W/cm. The core inlet temperature for liquid lead or Pb/Bi eutectic is 420 C. The design includes approximately seventy-five data measurements such as pressure, temperature, and flow rates. The preliminary estimated cost of construction of the facility is $3.7M. It is also estimated that the facility will require two years to be constructed and ready for operation

    2017-11-01

    Full Text Available The article is aimed at generalizing the foreign experience of implementing public procurement, analyzing peculiarities of organizational, normative and procedural provision of public procurement in the Member States of the European Union. The relevance of the research topic is due to the need to harmonize the procurement policy of the Government of Ukraine with the international legal framework and with broad political objectives within the European integration strategy. The organizational framework and principles of implementing public procurement in the EU Member States were analyzed. Special attention was paid to normative provision of public procurement by the EU Member States; peculiarities of the use of national or harmonized rules of public procurement in accordance with the amount of the procurement contract; restrictions and conditions for public authorities in the selection of applicants for bidding. Five types of public procurement procedures used in the EU have been characterized, namely: open procedure, limited procedure, negotiation procedure, competitive dialog, electronic auctions. The need to address the social and legal aspects of public procurement in international practice has been substantiated and the possibilities for resolving these problems have been presented.

    Full Text Available Public procurement represents an important part of the current economy reality. Throughout the procurement process, due to the effect of the interaction among the components of the public procurement system, certain actions with significant negative effects on its optimal operation may occur. Risks may turn into certainty either because of a simple error in the development and administration of the procurement process, or because of a deliberate deviation from the existing legal provisions. Therefore, there is an imperative for the implementation of certain risk-avoiding measures, as well as of measures aiming to reduce their negative effects in case of their occurrence.

  15. Construction and testing of a blower-door assembly for regulation of air pressure within structures

    International Nuclear Information System (INIS)

    Steele, W.D.

    1987-09-01

    The Technical Measurements Center is evaluating several methods to decrease the time required to determine an annual average radon-daughter concentration in structures. One method involves stabilizing the air pressure within the structure at a constant pressure with reference to external atmospheric or soil-gas pressure. This report describes the construction and preliminary testing of a blower-door system to maintain a constant differential air pressure within a structure. The blower-door assembly includes a collapsible frame and a large fan to occlude a doorway, a damper with an actuator to control air flow, a controller to drive the damper actuator, and a pressure transducer to measure the differential pressure. Preliminary testing of the system indicates that pressure within the structure in the range of 1 to 20 Pascals can be held to within approximately +-1 Pa of the set point. Further testing of the blower-door system is planned to provide data on the applicability of this method to short-duration tests for annual average radon-daughter concentration estimates. 13 figs., 1 tab

The apparatus will be mounted in a chamber, heated with lamps, and tested in a vacuum chamber with LN2-cooled walls. Simulation of the test bed was accomplished using a DEC PRO 350 computer and the software package TK! olver. Key input variables were absorbed solar radiation and cold plate loads. The results indicate temperatures on the two loops will be nominal when the radiation and cold plate loads are in the range of 25% to 75% of peak loads. If all loads fall to zero, except the cabin air system which was fixed, the radiator fluid will drop below -100 F and may cause excessive pressure drop. If all loads reach 100%, the cabin air temperature could rise to 96 F.

    Experimental research on hydrogen as a combustible gas is important for an assessment of the integrity of a containment building under a severe accident. The Korea Atomic Energy Research Institute (KAERI) is preparing a large-scaled test facility, called SPARC (SPray-Aerosol-Recombiner-Combustion), to estimate the hydrogen behavior such as the distribution, combustion and mitigation. This paper introduces the experimental research activity on hydrogen risk, which was presented at International Congress on Advances in Nuclear Power Plants (ICAPP) this year. The KAERI is preparing a test facility, called SPARC (SPray-Aerosol-Recombiner-Combustion test facility), for an assessment of the hydrogen risk. In the SPARC, hydrogen behavior such as mixing with steam and air, distribution, and combustion in the containment atmosphere will be observed. The SPARC consists of a pressure vessel with a 9.5 m height and 3.4 m in diameter and the operating system to control the thermal hydraulic conditions up to 1.5 MPa at 453 K in a vessel. The temperature, pressure, and gas concentration at various locations will be measured to estimate the atmospheric behavior in a vessel. To install the SPARC, an experimental building, called LIFE (Laboratory for Innovative mitigation of threats from Fission products and Explosion), was constructed at the KAERI site. LIFE has an area of 480 m''2 and height of 18.6 m, and it was designed by considering the experimental safety and specification of a large-sized test facility.

  18. Strategy for the procurement of electronics for the LHC experiments

    CERN Document Server

    2002-01-01

    At its meeting on 14 March 2001 the Finance Committee requested the preparation of a document outlining the strategy for future procurement of electronics for the LHC experiments. The bulk of the electronics for the LHC experiments is based on custom-developed designs, the manufacturing of which will be contracted out to industry using the CERN purchasing procedures to ensure competitive prices. Analysis of on-going procurement activities for the electronics for the LHC experiments shows that in almost all cases the application of the CERN purchasing procedures has resulted in bids from a sufficient number of qualified companies to ensure competitive prices and a reasonable distribution of returns between CERN Member States. There is no reason to expect that this pattern will change significantly for the electronics that still remains to be purchased to complete the construction of the LHC experiments.

    Full Text Available The objective of this study was examining the factors affecting the government procurement fraud. Based on the fraud triangle and the theory of planned behavior, this study proposed seven hypothesis, those are tested by regression analysis. This study used primary data gathered by surveys to members of The Boards of the Republic Indonesia- Financial Auditors, who act as external auditors for the Government. They were asked to assess factors influencing the government procurement of goods and services fraud. There were 297 auditors of the Boards that participated in this survey. The result showed that the procurement frauds were influenced by the lack of procurement committee quality, the weakness of procurement control, and the intentions to engage fraud. The intentions to engage fraud were significantly influenced by the attitude toward fraud, subjective norms, and the perceived behavioral control. Furthermore, other elements of fraud triangle, the financial pressure, did not influence to the procurement fraud.

    The University of Missouri Research Reactor Facility (MURR) located in Columbia, Missouri, is the highest powered, highest steady-state flux university research reactor in the United States. The reactor is a 10-MW pressurized loop, in-pool-type, light-water-moderated, beryllium-reflected, flux trap reactor. MURR has a compact core (0.033 m 3 ) composed of eight fuel elements of the materials test reactor type arranged as an annular right circular cylinder between the inner and outer aluminum pressure vessels. Conservative engineering judgment resulted in the decision in 1988 to purchase new inner and outer pressure vessels. This paper details the difficulties encountered in procuring replacements for aluminum pressure vessels built to standards that are no longer applicable in attempting to meet nuclear standards that are not applicable to nonferrous material

    2016-05-01

    Full Text Available The transition from printed to electronic sources of information has resulted in a profound change to the way procurement officers seek information. Furthermore, in the past decade there have been additional technological revolutions that are expected to further affect the procurement process. In this paper, we conduct a survey among forty nine university procurement officers in Israel to examine to what extent procurement officers have adapted to smartphones and tablets by testing how frequently officers use notebooks, smartphones, and tablets for work-related and leisure purposes. We find that while officers prefer electronic sources of information over printed sources of information, officers have not yet adapted to the later technological advances (i.e., smartphones and tablets. Notebooks are more frequently used than either smartphones or tablets for work-related and leisure purposes. One explanation behind this result is that officers are not skilled in using smartphone and tablets applications. This implies that training officers in the use of these devices may improve their performance.

    Ptok, M; Kühn, D; Miller, S

    2014-04-01

    During first language acquisition (L1), children need to gather knowledge about the speech sounds and grammar of their mother tongue. Furthermore, communication skills require an adequate vocabulary. Individual profiles of vocabulary acquisition can vary considerably. However, actively using around 50 words by the age of 24 months is considered a milestone in first language acquisition. This is usually followed by the so-called vocabulary spurt, a rapid increase in lexical knowledge. This article provides an overview of the theories of lexical development and discusses how the acquisition of vocabulary may be explained. A selective literature search was conducted in PubMed and Scopus. Current textbooks were also considered. In order to acquire new words, a child has to identify what the new string of speech sounds refers to. The child has to construct a valid concept of the word and subsequently store both word and concept into long-term memory. Several theories have been put forward to explain lexicon organization, the acquisition of concepts and the mechanisms underlying the so-called fast mapping phenomenon in particular. All of these attempt to explain the phenomenon of lexicon acquisition in terms of a model scheme. In the context of the fast mapping mechanism, constraints and assumptions, cognitive, intentionalist and emergence-based theories are discussed. Knowledge of the different theories of vocabulary acquisition is mandatory to understand the construction of the tests used to assess vocabulary skills in clinical practice and to apply these appropriately.

  10. The impact of image test bank construction on radiographic interpretation outcomes: A comparison study

    International Nuclear Information System (INIS)

    Hardy, M.; Flintham, K.; Snaith, B.; Lewis, E.F.

    2016-01-01

    Introduction: Assessment of image interpretation competency is commonly undertaken through review of a defined image test bank. Content of these image banks has been criticised for the high percentage of abnormal examinations which contrasts with lower reported incidences of abnormal radiographs in clinical practice. As a result, questions have been raised regarding the influence of prevalence bias on the accuracy of interpretive decision making. This article describes a new and novel approach to the design of musculoskeletal image test banks. Methods: Three manufactured image banks were compiled following a standard academic menu in keeping with previous studies. Three further image test banks were constructed to reflect local clinical workload within a single NHS Trust. Eighteen radiographers, blinded to the method of test bank composition, were randomly assigned 2 test banks to review (1 manufactured, 1 clinical workload). Comparison of interpretive accuracy was undertaken. Results: Inter-rater agreement was moderate to good for all image banks (manufactured: range k = 0.45–0.68; clinical workload: k = 0.49–0.62). A significant difference in mean radiographer sensitivity was noted between test bank designs (manufactured 87.1%; clinical workload 78.5%; p = 0.040, 95% CI = 0.4–16.8; t = 2.223). Relative parity in radiographer specificity and overall accuracy was observed. Conclusion: This study confirms the findings of previous research that high abnormality prevalence image banks over-estimate the ability of observers to identify abnormalities. Assessment of interpretive competency using an image bank that reflects local clinical practice is a better approach to accurately establish interpretive competency and the learning development needs of individual practitioners. - Highlights: • High prevalence image test banks over-estimate the ability of observers. • Clinical workload test banks may better reflect image interpretation competency.

    This report consists of three sections. The first is concerned with the description of different pumps which have been constructed, tests on these which have been completed and the results obtained. The second section presents a theoretical method for the determination of the coefficients, taking in account the break of the magnetic circuit. It is shown that the preliminary design calculations of the annular pumps can be made, neglecting the break of the magnetic circuit, by further assigning essential magnitudes (pressure, losses) with easily calculated coefficients. The third section of this report uses the theoretical bases exposed in the second section, and develop a new annular pump calculation method which takes-into account both the current out of balance and any type of winding.

    A system of mechanical components has been develoed, which can be used to design inert atmosphere boxes as well as radioactive boxes. The advantage in comparison with known designs consists in the modular construction principle which permits variable dimensions. Standard parts (flanges, bushings, air locks and so on) possess a uniform size. The system for the maintenance of a high-purity atmosphere in the box has been improved, decreasing the level of oxygen and water vapour below 10 vpm. The low impurity level in the inert atmosphere is attained by means of continuous circulation of the gases through a purification system. The usefulness of the boxes for handling air-sensitive and radioactive compounds has been tested over a period of some years. (author)

    The CERN is planning the construction of a new particle collider, the LHC, a p-p collider which operational energies will be greater than 1 TeV. A position detector or preshower detector will form a part of the Atlas detector which will analyze the interaction products; it will be used to spatially identify the disintegration of the Higgs boson, the signature of the Higgs mechanism into two photons. It will also provide an energy correction for the electromagnetic calorimeter. This paper gives simulation results for its spatial and angular resolution as well as the energy resolution achieved for the electromagnetic calorimeter when the preshower's energy correction is applied. A prototype and beam tests are presented; results are compared with those of Monte Carlo simulations. 110 fig., 31 ref

    The Alto Douro Wine Region, located in the northeast of Portugal, a UNESCO World Heritage Site, presents an abundant vernacular building heritage. This building technology is based on a timber framed structure filled with a composite earth-based material. A lack of scientific studies related to this technology is evident, furthermore, principally in rural areas, this traditional building stock is highly deteriorated and damaged because of the rareness of conservation and strengthening works, which is partly related to the non-engineered character of this technology and to the knowledge loosed on that technique. Those aspects motivated the writing of this paper, whose main purpose is the physical and chemical characterization of the earth-based material applied in the tabique buildings of that region through field tests. Consequently, experimental work was conducted and the results obtained allowed, among others, the proposal of a series of adequate field tests. At our knowledge, this is the first time field tests are undertaken for tabique technology. This information will provide the means to assess the suitability of a given earth-based material with regards to this technology. The knowledge from this study could also be very useful for the development of future normative documents and as a reference for architects and engineers that work with this technology to guide and regulate future conservation, rehabilitation or construction processes helping to preserve this important legacy.

    2016-01-01

    Full Text Available The construction of spectral discoloration model, based on aging test and simulating degradation experiment, was proposed to detect the aging degree of red lead pigment in ancient murals and to reproduce the spectral data supporting digital restoration of the ancient murals. The degradation process of red lead pigment under the aging test conditions was revealed by X-ray diffraction, scanning electron microscopy, and spectrophotometer. The simulating degradation experiment was carried out by proportionally mixing red lead and lead dioxide with referring to the results of aging test. The experimental result indicated that the pure red lead was gradually turned into black lead dioxide, and the amount of tiny particles of the aging sample increased faced with aging process. Both the chroma and lightness of red lead pigment decreased with discoloration, and its hue essentially remains unchanged. In addition, the spectral reflectance curves of the aging samples almost started rising at about 550 nm with the inflection moving slightly from about 570 nm to 550 nm. The spectral reflectance of samples in long- and in short-wavelength regions was fitted well with the logarithmic and linear function. The spectral discoloration model was established, and the real aging red lead pigment in Dunhuang murals was measured and verified the effectiveness of the model.

  20. Construction and test of a superconducting phase-transition thermometer for bolometric cryodetectors

    1990-10-01

    In the framework of a project for the study of bolometric cryodetectors for the detection of heavy ions a superconducting phase-transition thermometer for the detection of heavy ions was constructed and tested with α particles. The thermometer consists of a 10 nm thick aluminium film, which was evaporated on a sapphire absorber with a typical magnitude of 2.5x2.5 x 0.33 mm 3 . By the method of photolithography the aluminium film was structured in form of a meander. By this at the working point of the thermometer resistances of up to 60 kΩ resulted, so that the signal acquisition was possible with usual readout electronics. Several of these thermometers were constructed, characterized in their properties, and tested. For the study of the detector properties of the thermometers in characterization measurements the width of the phase transitions dT ≅ 2 mK, the temperature dependence of the resistance to dR/dT ≅ 10MΩ/K, the thermal conductivity of the thermal coupling to the cooling bath, and the heat capacity of the bolometers to C ≅ 2 nJ/K were determined.The best energy resolution, which was reached with one of the superconducting phase-transition thermometers, amounts to 50 keV for 5.5 MeV α particles, which corresponds to a relative resolution of 0,9%. By this in the order of magnitude the quality of semiconductor detectors was reached. The best temperature resolution amounts to about 1 μK. (orig./HSI) [de

    Pongpanga Pongsuwan

    2016-11-01

    Full Text Available This study refers to the research model of Batenburg (2008 which defined procurement functions to six maturity dimensions; strategy, processes, control, organization, information, e-Technology as the starting point and indicates twenty two items to support capability maturity measurement which is called “Procurement Competitive Capability Maturity”(PCCM. This model is used for a company to assess current practices of procurement function and perceives the level of its capabilities. The data collection is from a survey of fifty-two selected procurement organizations in Southeast Asia (SEA countries; from Thailand, Vietnam, Philippines, Indonesia, Malaysia and Singapore. The objective of this study is to demonstrate the significant value of industry type, size of spending and centralized/decentralized procurement that affect procurement capability maturity. The results show that the industry has no relation to the capability maturity; the size of procurement spend has a positive relation to the capability maturity; and the centralized procurement has higher capability maturity than the decentralized. Moreover, this study extends the knowledge of e-Procurement and digital context to leverage procurement processes and visible procurement integration in an organization and across the supply chain.

    2015-01-01

    After completing construction of TNPS Phase I, some of supports and hangers supplied by Russia including many nuclear safety class supports and hangers were unexpectedly found quality problem. It is necessary to purchase the domestic product as replacement. The works on modification of supports and hangers became one of the key paths of TNPS construction. Under condition of that there isn't any reference in this aspect in nuclear power construction, Jiangsu Nuclear Power Corporation has always adhered to the principle of 'Safety first and quality first', overcome many difficulties of procurement, carried out the procurement work scientifically and reasonably under the condition of urgent need for the engineering construction, and ensured the quality control and schedule control. A large amount of procurement works for the modified supports and hangers were finished within short period. This firmly assured the construction period of TNPS. At the same time, a method of procurement management under the condition of urgent need for the engineering construction has been explored. (author)

    2014-08-01

    The Implicit Positive and Negative Affect Test (IPANAT) is an instrument for the indirect assessment of positive and negative affect. A Japanese version of the IPANAT was developed and its reliability and validity were examined. In Study 1, factor analysis identified two independent factors that could be interpreted as implicit positive and negative affect, which corresponded to the original version. The Japanese IPANAT also had sufficient internal consistency and acceptable test-retest reliability. In Study 2, we demonstrated that the Japanese IPANAT was associated with explicit state affect (e.g., PANAS), extraversion, and neuroticism, which indicated its adequate construct validity. In Study 3, we examined the extent to which the Japanese IPANAT was sensitive to changes in affect by assessing a set of IPANAT items after the presentation of positive, negative, or neutral photographs. The results indicated that the Japanese IPANAT was sufficiently sensitive to changes in affect resulting from affective stimuli. Taken together, these studies suggest that the Japanese version of the IPANAT is a useful instrument for the indirect assessment of positive and negative affect.

    2003-01-01

    Targets must be injected into an IFE power plant at a rate of approximately 5 to 10 Hz. Targets must be tracked very accurately to allow driver beams to be aligned with defined points on the targets with accuracy ± 150 (micro)m for indirect drive and ± 20 (micro)m for direct drive. An experimental target injection and tracking system has been constructed at General Atomics. The injector system will be used as a tool for testing the survivability of various target designs and provide feedback to the target designers. Helium gas propels the targets down an 8 m gun barrel up to 400 m/s. Direct-drive targets are protected in the barrel by sabots that are spring loaded to separate into two halves after acceleration. A sabot deflector directs the sabot halves away from the target injection path. Targets will be optically tracked with laser beams and line-scan cameras. Target position and arrival time will be predicted in real time based on early target position measurements. The system installation will be described. System testing to overcome excessive projectile wear and debris in the gun barrel is presented

  5. Construction of an Exome-Wide Risk Score for Schizophrenia Based on a Weighted Burden Test.

    Science.gov (United States)

    Curtis, David

    2018-01-01

    Polygenic risk scores obtained as a weighted sum of associated variants can be used to explore association in additional data sets and to assign risk scores to individuals. The methods used to derive polygenic risk scores from common SNPs are not suitable for variants detected in whole exome sequencing studies. Rare variants, which may have major effects, are seen too infrequently to judge whether they are associated and may not be shared between training and test subjects. A method is proposed whereby variants are weighted according to their frequency, their annotations and the genes they affect. A weighted sum across all variants provides an individual risk score. Scores constructed in this way are used in a weighted burden test and are shown to be significantly different between schizophrenia cases and controls using a five-way cross-validation procedure. This approach represents a first attempt to summarise exome sequence variation into a summary risk score, which could be combined with risk scores from common variants and from environmental factors. It is hoped that the method could be developed further. © 2017 John Wiley & Sons Ltd/University College London.

    In this work we designed and built a Plasma Focus device 2kJ power in order to extend the energy range of devices designed in DPTN CCHEN and study the scaling laws type Plasma Focus Device. The operating parameters of this device are: T/ 4 =907ns, C = 8000nF, L = 42nH, E = 2kJ, lo = 276kA. In such a way to optimize the device tests were performed with various electrode configurations, insulator length, to determine the conditions under which it operates in Plasma Focus mode. Subsequent to the construction tests were performed on devices PF-400J (T /4 = 300ns, C = 880nF, L = 38nH, E = 400J, lo = 168kA) y PF-2kJ (device between the hundreds of joules and kilojoules of energy) diagnostic charged particle emission used the Faraday Cup consisting of a biased graphite collector. For a series of shots on the PF-400J and PF-2kJ operated at 27kV and 20kV respectively kinetic energy distribution of proton between 60keV-150keV were found, deuterons between 60KeV-300KeV. With the idea of optimizing the results in future diagnostic type spectrometer Thompson, spectroscopy and diffraction networks in gas mixture will be implemented

  7. Siting and constructing very deep monitoring wells on the US Department of Energy's Nevada Test Site

    International Nuclear Information System (INIS)

    Cullen, J.J.; Jacobson, R.L.; Russell, C.E.

    1991-01-01

    Many aspects of the Nevada Test Site's (NTS) hydrogeologic setting restrict the use of traditional methods for the siting and construction of ground-water characterization and monitoring wells. The size of the NTS precludes establishing high-density networks of characterization wells, as are typically used at smaller sites. The geologic complexity and variability of the NTS requires that the wells be criticality situated. The hydrogeologic complexity requires that each well provide access to many aquifers. Depths to ground water on the NTS require the construction of wells averaging approximately 1000 meters in depth. Wells meeting these criteria are uncommon in the ground-water industry, therefore techniques used by petroleum engineers are being employed to solve certain siting-, design- and installation-related problems. To date, one focus has been on developing completion strings that facilitate routine and efficient ground-water sampling from multiple intervals in a single well. The method currently advocated employs a new design of sliding side door sleeve that is actuated by an electrically operated hydraulic shifting tool. Stemming of the wells is being accomplished with standard materials (cement based grouts and sands); however, new stemming methods are being developed, to accommodate the greater depths, to minimize pH-related problems caused by the use of cements, to enhance the integrity of the inter-zone seals, and to improve the representativeness of radionuclide analyses performed on ground-water samples. Bench-scale experiments have been used to investigate the properties of more than a dozen epoxy-aggregate grout mixtures -- materials that are commonly used in underwater sealing applications

    To our knowledge, yield strength testing in human nasal septal cartilage has not been reported to date. An understanding of the basic mechanics of the nasal septum may help surgeons decide how much of an L-strut to preserve and how much grafting is needed. To determine the factors correlated with yield strength of the cartilaginous nasal septum and to explore the association between L-strut width and thickness in determining yield strength. In an anatomy laboratory, yield strength of rectangular pieces of fresh cadaver nasal septal cartilage was measured, and regression was performed to identify the factors correlated with yield strength. To measure yield strength in L-shaped models, 4 bonded paper L-struts models were constructed for every possible combination of the width and thickness, for a total of 240 models. Mathematical modeling using the resultant data with trend lines and surface fitting was performed to quantify the associations among L-strut width, thickness, and yield strength. The study dates were November 1, 2015, to April 1, 2016. The factors correlated with nasal cartilage yield strength and the associations among L-strut width, thickness, and yield strength in L-shaped models. Among 95 cartilage pieces from 12 human cadavers (mean [SD] age, 67.7 [12.6] years) and 240 constructed L-strut models, L-strut thickness was the only factor correlated with nasal septal cartilage yield strength (coefficient for thickness, 5.54; 95% CI, 4.08-7.00; P cadaver nasal septal cartilage, L-strut thickness was significantly associated with yield strength. In a bonded paper L-strut model, L-strut thickness had a more important role in determining yield strength than L-strut width. Surgeons should consider the thickness of potential L-struts when determining the amount of cartilaginous septum to harvest and graft. NA.

  9. Assessing the environmental performance of construction materials testing using EMS: An Australian study.

    Science.gov (United States)

    Dejkovski, Nick

    2016-10-01

    This paper reports the audit findings of the waste management practices at 30 construction materials testing (CMT) laboratories (constituting 4.6% of total accredited CMT laboratories at the time of the audit) that operate in four Australian jurisdictions and assesses the organisation's Environmental Management System (EMS) for indicators of progress towards sustainable development (SD). In Australia, waste indicators are 'priority indicators' of environmental performance yet the quality and availability of waste data is poor. National construction and demolition waste (CDW) data estimates are not fully disaggregated and the contribution of CMT waste (classified as CDW) to the national total CDW landfill burden is difficult to quantify. The environmental and human impacts of anthropogenic release of hazardous substances contained in CMT waste into the ecosphere can be measured by construing waste indicators from the EMS. An analytical framework for evaluating the EMS is developed to elucidate CMT waste indicators and assess these indicators against the principle of proportionality. Assessing against this principle allows for: objective evaluations of whether the environmental measures prescribed in the EMS are 'proportionate' to the 'desired' (subjective) level of protection chosen by decision-makers; and benchmarking CMT waste indicators against aspirational CDW targets set by each Australian jurisdiction included in the audit. Construed together, the EMS derived waste indicators and benchmark data provide a composite indicator of environmental performance and progress towards SD. The key audit findings indicate: CMT laboratories have a 'poor' environmental performance (and overall progress towards SD) when EMS waste data are converted into indicator scores and assessed against the principle of proportionality; CMT waste recycling targets are lower when benchmarked against jurisdictional CDW waste recovery targets; and no significant difference in the average

    Verma, D.K.; Moss, V.J.

    1987-02-01

    The Tarapur Atomic Power Station (TAPS) was the first nuclear power station in developing countries and the first twin BWR units in the world. The Station has two units of boiling water reactor of very early design; along with its turbo-generator and supporting systems; constructed by M/s. I.G.E. on turnkey basis. Based on vendor recommendations initial operating spares for 5 years of operation were purchased from original equipment manufacturers. This does not call for the participation of the ultimate user; in the design, development, manufacture and quality control and user's participation remained confined to assemble the acceptable component(s) procured from original source in the assembly. As early as 1972, Plant initiated indigenising the nuclear components by gradually increasing the contribution of indigenous industry with due participation of the departmental agencies. Procurement of nuclear components requires development of engineering to an extent; where interphase communication between TAPS and counterpart indigenous industry is practicable to motivate them. Feedback from operation and maintenance practices is also utilised effectively. For some of the components initial sample were developed at TAPS and subsequently bulk fabrication was taken by industry. This paper describes manufacture, quality control during the process of manufacture and procurement of indigenous nuclear components relevant to Tarapur Atomic Power Station. (author)

    2017-12-01

    Full Text Available A well implemented good practice of Design-Build procurement method brings different disciplines and aspects of construction process together, which in turn minimizes the incidents of constructors having to repeat work, and thus, result in cost and time savings. This type of procurement method increases the probability of a successful project that meets the expectations of all stakeholders. A bad practice of Design–Build procurement method increases the probability that the project’s performance will be compromised and that some or all of the stakeholders disappointed. The aim of this research is to determine whether Design-build procurement method is rightly practiced in South Africa. Data were collected from consultants and contractors using a structured questionnaire via personal contact and email. The collected data were subjected to descriptive statistical analyses. This paper argues that design-build procurement is not correctly practiced in South Africa. This may be due to the late introduction and the level of understanding of the procurement method.

    CREAM (Cosmic Ray Energetics And Mass) is a balloon-borne experiment being prepared for the first flight which is scheduled for the end of 2004 from Antarctica. It is designed to perform direct measurements of cosmic ray composition over the elemental range from proton to iron to the supernova energy scale of 10 15 eV in a series of balloon flights using the new Ultra Long Duration Balloon (ULDB) capability under development by NASA. The instrument includes a sampling tungsten/scintillating fiber calorimeter preceded by a graphite target with scintillating fiber hodoscopes, a pixelated silicon charge detector, a transition radiation detector and a segmented timing-based particle-charge detector. The hodoscope system provides track reconstruction capability by means of 4 orthogonal layers of fibers (S0,S1) on top of the carbon target and 2 additional layers (S2) located in between the upper and lower target sections. Its construction technique and beam test results are presented

    We report the construction and the tests of a small prototype of the lead-scintillating fiber calorimeter of the KLOE experiment, instrumented with multianode photomultipliers to obtain a 16 times finer readout granularity. The prototype is 15 cm wide, 15 radiation lengths deep and is made of 200 layers of fibers 50 cm long. On one side it is read out with an array of 3x5 multianode photomultipliers Hamamatsu type R8900-M16, each segmented with 4x4 anodes, the read out granularity being 240 pixels of 11 x 11 mm 2 corresponding to about 64 scintillating fibers each. These are interfaced to the 6 x 6 mm 2 pixeled photocathode with truncated pyramid light guides made of Bicron BC-800 plastic to partially transmit the UV light. Each photomultiplier provides also an OR of the 16 last dynodes that is used for trigger. The response of the individual anodes, their relative gain and cross-talk has been measured with the light (440 nm) of a laser illuminating only few fibers on the side opposite to the readout. We finally present the first results of the calorimeter response to cosmic rays in auto-trigger mode.

    Concerning about global warming due to emission of greenhouse effect gas like CO 2 , it is essentially important to make efforts to obtain more reliable and stable energy supply by extended use of nuclear energy including high temperature heat from nuclear reactors, because it can supply a large amount of energy and its plants emit only little amount of CO 2 during their lifetime. Hence, efforts are to be continuously devoted to establish and upgrade technologies of High Temperature Gas-cooled Reactor (HTGR) which can supply high-temperature heat with high thermal efficiency as well as high heat-utilizing efficiency. It is also expected that making basic researches at high temperature using HTGR will contribute to innovative basic research in future. Then, the construction of High Temperature engineering Test Reactor (HTTR), which is an HTGR with a maximum helium coolant temperature of 950 deg. C at the reactor outlet, was decided by the Japanese Atomic Energy Commission (JAEC) in 1987 and is now under way by the Japan Atomic Energy Research Institute (JAERI). 2 refs, 2 figs, 1 tab., 2 photos

  1. Overcoming the effects of differential skewness of test items in scale construction

    Directory of Open Access Journals (Sweden)

    Johann M. Schepers

    2004-10-01

    Full Text Available The principal objective of the study was to develop a procedure for overcoming the effects of differential skewness of test items in scale construction. It was shown that the degree of skewness of test items places an upper limit on the correlations between the items, regardless of the contents of the items. If the items are ordered in terms of skewness the resulting inter correlation matrix forms a simplex or a pseudo simplex. Factoring such a matrix results in a multiplicity of factors, most of which are artifacts. A procedure for overcoming this problem was demonstrated with items from the Locus of Control Inventory (Schepers, 1995. The analysis was based on a sample of 1662 first year university students. Opsomming Die hoofdoel van die studie was om ’n prosedure te ontwikkel om die gevolge van differensiële skeefheid van toetsitems, in skaalkonstruksie, teen te werk. Daar is getoon dat die graad van skeefheid van toetsitems ’n boonste grens plaas op die korrelasies tussen die items ongeag die inhoud daarvan. Indien die items gerangskik word volgens graad van skeefheid, sal die interkorrelasiematriks van die items ’n simpleks of pseudosimpleks vorm. Indien so ’n matriks aan faktorontleding onderwerp word, lei dit tot ’n veelheid van faktore waarvan die meerderheid artefakte is. ’n Prosedure om hierdie probleem te bowe te kom, is gedemonstreer met behulp van die items van die Lokus van Beheer-vraelys (Schepers, 1995. Die ontledings is op ’n steekproef van 1662 eerstejaaruniversiteitstudente gebaseer.

    After forward-backward translation, the LSS was administered to 334 Persian speaking, cognitively healthy elderly aged 60 years and over recruited through convenience sampling. To analyze the validity of the model's constructs and the relationships between the constructs, a confirmatory factor analysis followed by PLS analysis was performed. The Construct validity was further investigated by calculating the correlations between the LSS and the "Short Form Health Survey" (SF-36) subscales measuring similar and dissimilar constructs. The LSS was re-administered to 50 participants a month later to assess the reliability. For the eight-factor model of the life satisfaction construct, adequate goodness of fit between the hypothesized model and the model derived from the sample data was attained (positive and statistically significant beta coefficients, good R-squares and acceptable GoF). Construct validity was supported by convergent and discriminant validity, and correlations between the LSS and SF-36 subscales. Minimum Intraclass Correlation Coefficient level of 0.60 was exceeded by all subscales. Minimum level of reliability indices (Cronbach's α, composite reliability and indicator reliability) was exceeded by all subscales. The Persian-version of the Life Satisfaction Scale is a reliable and valid instrument, with psychometric properties which are consistent with the original version.

    Full Text Available Green Public Procurement (GPP is defined as a process of contracting products, services, and works with the least possible damage to the environment during their life cycle. In order to improve the knowledge about GPP, a study of the use of environmental tendering criteria in the Spanish public construction sector has been performed. The results of this study show that the use of environmental criteria in Spanish public sector construction procurement is low in comparison to a certain group of countries, known as “Green 7”, in the European Union. Environmental criteria is the fourth criterion in importance, but its weight in the global of the process is much lower than other criteria such as price, memory of the construction process and the delivery time. National administrations use environmental criteria more frequently because they have more resources and staff training about environmental issues. Environmental criteria are more used in the tendering of civil projects and works whose budget exceeds ten million euro due to the environmental impact of these kind and/or size of projects.

  7. Government Procurement Agreements and Telecommunications Business

    Directory of Open Access Journals (Sweden)

    Shin-Won Kang

    2001-12-01

    Full Text Available The opening of the telecommunications market is acceleration due to the world trends of deregulation and privatization under the WTO basic telecommunications agreements. Diversification of services and fast and efficient equipment procurement are becoming necessary conditions for the survival of telecommunications operators. However, the issue here is that telecommunications operators are still bound by the GPA (Government Procurement Agreement based on conditions of monopoly even though the procurement market in Korean is open substantially since 1997. Under such conditions, the continued application of the GPA on telecommunications operator who is highly competitive may result in a negative impact on the telecommunications business and quality of telecommunications service by undermining the autonomy of operator and decreasing operator’s procurement competitiveness. Therefore, this study examines the GPA and the issues raised by the agreement, and also attempts to suggest revisions or means of abrogating the unfair GPA with regards to the development and deregulation of the telecommunications business.

  10. Factors influencing global antiretroviral procurement prices.

    Wirtz, Veronika J; Forsythe, Steven; Valencia-Mendoza, Atanacio; Bautista-Arredondo, Sergio

    2009-11-18

    Antiretroviral medicines (ARVs) are one of the most costly parts of HIV/AIDS treatment. Many countries are struggling to provide universal access to ARVs for all people living with HIV and AIDS. Although substantial price reductions of ARVs have occurred, especially between 2002 and 2008, achieving sustainable access for the next several decades remains a major challenge for most low- and middle-income countries. The objectives of the present study were twofold: first, to analyze global ARV prices between 2005 and 2008 and associated factors, particularly procurement methods and key donor policies on ARV procurement efficiency; second, to discuss the options of procurement processes and policies that should be considered when implementing or reforming access to ARV programs. An ARV-medicines price-analysis was carried out using the Global Price Reporting Mechanism from the World Health Organization. For a selection of 12 ARVs, global median prices and price variation were calculated. Linear regression models for each ARV were used to identify factors that were associated with lower procurement prices. Logistic regression models were used to identify the characteristics of those countries which procure below the highest and lowest direct manufactured costs. Three key factors appear to have an influence on a country's ARV prices: (a) whether the product is generic or not; (b) the socioeconomic status of the country; (c) whether the country is a member of the Clinton HIV/AIDS Initiative. Factors which did not influence procurement below the highest direct manufactured costs were HIV prevalence, procurement volume, whether the country belongs to the least developed countries or a focus country of the United States President's Emergency Plan For AIDS Relief. One of the principal mechanisms that can help to lower prices for ARV over the next several decades is increasing procurement efficiency. Benchmarking prices could be one useful tool to achieve this.

    A vast amount of public services and goods are contracted through procurement auctions. Therefore it is very important to design these auctions in an optimal way. Typically, we are interested in two different objectives. The first objective is efficiency. Efficiency means that the contract is awarded to the bidder that values it the most, which in the procurement setting means the bidder that has the lowest cost of providing a service with a given quality. The second objective is to maximize ...

    We have constructed and completed the preparation for a long-term operation test of a superconducting fault current limiter (SFCL) in a Korea Electric Power Corporation (KEPCO) test grid. The SFCL with rating of 22.9 kV/630 A, 3-phases, has been connected to the 22.9 kV test grid equipped with reclosers and other protection devices in Gochang Power Testing Center of KEPCO. The main goals of the test are the verification of SFCL performance and protection coordination studies. A line-commutation type SFCL was fabricated and installed for this project, and the superconducting components were cooled by a cryo-cooler to 77 K in the sub-cooled liquid nitrogen pressurized by 3 bar of helium gas. The verification test includes un-manned - long-term operation with and without loads and fault tests. Since the test site is 170 km away from the laboratory, we will adopt the un-manned operation with real-time remote monitoring and controlling using high speed internet. For the fault tests, we will apply fault currents up to around 8 kArms to the SFCL using an artificial fault generator. The fault tests may allow us not only to confirm the current limiting capability of the SFCL, but also to adjust the SFCL - recloser coordination such as resetting over-current relay parameters. This paper describes the construction of the testing facilities and discusses the plans for the verification tests.

  20. An evaluation of transit procurement training.

    Science.gov (United States)

    Noland, Robert B; Weiner, Marc D; Klein, Nicholas J; Puniello, Orin D

    2017-04-01

    We evaluated a training course called "Orientation to Transit Procurement", designed and conducted by the National Transit Institute. This course is designed to provide Federal Transit Administration (FTA) grantees an overview of regulations and best practices related to the procurement process. Our objective in conducting the evaluation was to understand how transit agency staff made changes in procurement practices in response to the course training. The evaluation was mixed mode: an Internet survey followed by in-depth interviews with a small group of respondents. Survey respondents were also provided with an open-ended question providing us with additional context for our evaluation. Results show that the training is substantially successful at meeting the goal of improving procurement practices at transit agencies; indeed, most respondents report making changes at their agencies as the proximate result of the training. This was at odds with our exploration of knowledge of procurement topics, as most respondents gave inaccurate answers on multiple-choice "knowledge questions". This may have been due to question structure or, more likely, the nature of online surveys. Suitable training on the procurement of information technology was also a main concern. The lack of training in this area is indicative of the broader challenge facing public transit agencies in how to incorporate new forms of technology into their existing practices and bureaucratic structures.
