    Ituarte, Iñigo Flores; Coatanea, Eric; Salmi, Mika; Tuomi, Jukka; Partanen, Jouni

    Additive manufacturing (AM) is expanding the manufacturing capabilities. However, quality of AM produced parts is dependent on a number of machine, geometry and process parameters. The variability of these parameters affects the manufacturing drastically and therefore standardized processes and harmonized methodologies need to be developed to characterize the technology for end use applications and enable the technology for manufacturing. This research proposes a composite methodology integrating Taguchi Design of Experiments, multi-objective optimization and statistical process control, to optimize the manufacturing process and fulfil multiple requirements imposed to an arbitrary geometry. The proposed methodology aims to characterize AM technology depending upon manufacturing process variables as well as to perform a comparative assessment of three AM technologies (Selective Laser Sintering, Laser Stereolithography and Polyjet). Results indicate that only one machine, laser-based Stereolithography, was feasible to fulfil simultaneously macro and micro level geometrical requirements but mechanical properties were not at required level. Future research will study a single AM system at the time to characterize AM machine technical capabilities and stimulate pre-normative initiatives of the technology for end use applications.

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    Külekçi, Murat

    2010-07-01

    The main purpose of this study was to examine the technical efficiency of farms producing sunflower in Erzurum, Turkey and to identify factors that might be causing inefficiency. Stochastic frontier analysis was used to measure technical efficiency. One hundred and seventeen randomly selected farms were interviewed for farm-level data in the 2004-2005 production period. Results revealed that the mean technical efficiency for the sunflower farms, estimated by the stochastic production frontier, is 64%. At full technical efficiency, on average, the farmers could reduce their inputs by around 56% without reducing their sunflower production, simply by improving technical efficiency. In the inefficiency model the parameter estimates showed that older farmers, higher level of farmer's education, more experienced farmers, larger farm size and higher information score resulted in lower technical inefficiency, while bigger family size and more credit usage resulted in higher technical inefficiency. This study proposes strategies such as providing better extension services and farmer-training programmes, including more educated people in sunflower farming and also expanding the sunflower-growing area through provision of adequate facilities in order to increase technical efficiency.

    2012-01-01

    Complexity theory has been adopted by a number of studies as a benchmark to investigate the performance of socio-technical systems, especially those that are characterized by relevant cognitive work. However, there is little guidance on how to assess, systematically, the extent to which a system is complex. The main objective of this study is to carry out a systematic analysis of a SAMU (Mobile Emergency Medical Service) Medical Regulation Center in Brazil, based on the core characteristics of complex systems presented by previous studies. The assessment was based on direct observations and nine interviews: three of them with regulator of emergencies medical doctor, three with radio operators and three with telephone attendants. The results indicated that, to a great extent, the core characteristics of complexity are magnified) due to basic shortcomings in the design of the work system. Thus, some recommendations are put forward with a view to reducing unnecessary complexity that hinders the performance of the socio-technical system.

  5. An Industrial System Powered by Wind and Coal for Aluminum Production: A Case Study of Technical Demonstration and Economic Feasibility

    Directory of Open Access Journals (Sweden)

    Jian-Xun Dong

    2012-11-01

    Full Text Available This paper presents a case study of an isolated industrial power system for aluminum production. The novel concept is that the cost of aluminum electrolysis can be significantly reduced by innovative application of hybrid systems incorporating wind energy and low-grade coal. In addition, the low-grade coal, which sale is not profitable in the market, can be locally consumed by the isolated power system. The power system thus fully utilizes the local resources in an effective and economic manner. However, several technical and economic issues are still of concern because the industrial system is isolated from the state grid. This paper hence discusses these issues and demonstrates the feasibility of such a hybrid power system from the technical and economic perspectives.

    2017-07-01

    Irrigated farming depends on an ample supply of water compatible quality. Presently, a lot of irrigation projects have to depend on inferior quality and not so enviable sources of water supply. In order to prevent troubles during usage of such water supplies of poor quality, there must be meticulous preparation to ensure that the water available with such quality characteristics is put to best use. The effect of water quality upon soil and crops must be better understood in choosing fitting options to manage with impending water quality associated troubles that might decrease soil and crop productivity under existing circumstances of water use. Two tanks (small sized reservoirs) namely, Walajah Tank and Perumal Tank in Cuddalore District, used for irrigation, receive mine drainage water pumped out continuously from the open cast lignite mines of the NLC India Limited, Neyveli, Tamilnadu State. This water has been used by the farmers in the irrigated commands of both Walajah Tank and Perumal Tank for more than three decades. Recently, the beneficiaries had raised fears on the quality of mine drainage waters they had been using for raising crops in the commands of both the tanks. They opined that the coal dust laden mine water used for irrigation had affected the crop yields. This incited us to take up a study to (i) assess the status of quality of surface waters released from the two tanks for irrigation in the respective command areas and (ii) assess the likely impacts of quality of water on soil and on growth and productivity of crops cultivated in the command areas. Further to the technical evaluation of the impacts, a structured questionnaire survey was also conducted among the farmers and the common public in the study area. The findings of the survey confirmed with the outcome of the technical assessment in that the mine drainage had a poor impact in the cultivable command area of Walajah tank system while such impacts were less significant in most parts of

    2016-03-01

    Problem-based learning (PBL) is a pedagogy that has attracted attention for many biomedical engineering curricula. The aim of the current study was to address the research question, 'Does PBL enable students to develop desirable professional engineering skills?' The desirable skills identified were communication, teamwork, problem solving and self-directed learning. Forty-seven students enrolled in a biomedical materials course participated in the case study. Students worked in teams to complete a series of problems throughout the semester. The results showed that students made significant improvements in their problem-solving skills, written communication and self-directed learning. Students also demonstrated an ability to work in teams and communicate orally. In conclusion, this case study provides empirical evidence of the efficacy of PBL on student learning. We discuss findings from our study and provide observations of student performance and perceptions that could be useful for faculty and researchers interested in PBL for biomedical engineering education.

    Directory of Open Access Journals (Sweden)

    IRINELA – CONSTANTINA BADEA

    2015-12-01

    Full Text Available The aim of this paper is to analyze the asset structure and the coverage of gross technical reserves of the Insurance – Reinsurance Company Astra SA, for the period 2003 – 2014. Insurance companies are required to constitute technical reserves, in order to cope with the payment obligations to policyholders. These reserves may only be covered on account of certain assets, admitted by law. In Romania, Orders No. 8 and 9/2011, issued by the Insurance Supervisory Commission, contain Rules regarding the assets admitted to cover gross technical reserves, the dispersion of assets admitted to cover gross technical reserves and the liquidity coefficient. Order No. 9/2011, relating to general insurance, has been amended by Rule No. 22/2014. In this paper, we have analyzed the main elements of Astra’s assets, their share in total assets and we have calculated the coverage of gross technical reserves by total assets and liquid assets. In 2013 and 2014, the value of total assets was below the value of gross tehnical reserves, which demonstrated Astra’s financial instability, through negative capital and the inability to meet the obligations to policyholders. Failure to comply with the prudential indicators has been one of the main causes of Astra`s bankruptcy.

  13. Impact of technical expertise in a nonmetropolitan siting dispute: a case study of the Hersey WFPP controversy

    Energy Technology Data Exchange (ETDEWEB)

    Frankena, F.

    1983-01-01

    This research study further illuminates public response to the scale of energy-resource development by examination of a case involving a renewable energy technology - a 25-MW wood-fired electric power plant (WFPP) to have been sited in the remote nonmetropolitan Michigan community of Hersey. The controversy began late in 1978 shortly after the three prime sites were announced and concluded in 1980 when the proposal was withdrawn in the face of a local hazardous and toxic waste ordinance. Offers followed from other communities while opposition continued to develop throughout the region. Using a case history approach that relies on a variety of data sources complemented by a content analysis of the Hersey site hearing and accounts from the local newspaper, this study focuses on a number of the salient issues of power plant siting. Foremost among these is the social and political impact of technical expertise. Expertise is evaluated in terms of facts/values and local/cosmopolitan orientations. Content analysis was also applied to the issues in the controversy. Policy implications are discussed for scale and centralization in energy development, the concomitant distribution of costs, and the use of technical expertise as a tool to depoliticize issues. This study suggests that public concerns relative to the scale of energy development may not be allayed by continued resort to expertise alone.

    Application of venture analysis would, at a minimum, need to address issues involving careful definition of the product/service being considered; market needs that the product will satisfy; investment/manufacturing costs; minimum selling price needed to achieve desired ROI or other financial measure; market potential at relevant prices; potential for competitors to obsolete the product before investment is recovered; assessment of companies' resources and capabilities to supply the product. There is clearly no single method for performing every venture analysis, because the economic and structural environment associated with each industry varies widely. These and other factors produce differences in cost structure, marketing organizations, and nature of products which dictate that an appropriate method of venture analysis must be tailored to each industry. The initial chapter of the report presents some brief remarks concerning the important concepts that all venture analyses must consider and then describes in detail the method used for the venture analyzed in this report. The case study addresses IEUS for commercialization. The type of IEUS investigated supplies electricity and thermal energy; the thermal energy distributed in the form of high-temperature water, i.e., water from at least 90/sup 0/C upwards to 200/sup 0/C.

    Improving energy efficiency is one of the strategic objectives of the European Union for rational energy economy. To make efforts to improve energy efficiency have been obliged both small and large end-users. This article aims to show the possibilities of improving energy efficiency by introducing technical and technological process changes of pine lumber drying. The object of the research is process of drying lumber implemented in a production company, which is a key supplier of large furniture manufacturer. Pine lumber drying chamber consume about 45% of total electricity in sawmill. According to various sources, drying of 1m3 of lumber uses about 3060kWh and is dependent of inter alia: the drying process itself, the factors affecting the processing time and the desired output moisture content of the timber. The article proposals for changes in the process of drying lumber pine have been positively validated in the company, and as a result their energy consumption per 1 m3 of product declined by 18%.

    Full Text Available Monitoring surface water velocity during flood events is a challenging task. Techniques based on deploying instruments in the flow are often unfeasible due to high velocity and abundant sediment transport. A low-cost and versatile technology that provides continuous and automatic observations is still not available. LSPIV (large scale particle imaging velocimetry is a promising approach to tackle these issues. Such technique consists of developing surface water velocity maps analyzing video frame sequences recorded with a camera. In this technical brief, we implement a novel LSPIV experimental apparatus to observe a flood event in the Tiber river at a cross-section located in the center of Rome, Italy. We illustrate results from three tests performed during the hydrograph flood peak and recession limb for different illumination and weather conditions. The obtained surface velocity maps are compared to the rating curve velocity and to benchmark velocity values. Experimental findings confirm the potential of the proposed LSPIV implementation in aiding research in natural flow monitoring.

    Training in non-technical skills (NTS) does not usually question the design of the work system, and thus focuses narrowly on workers as the unit of analysis. This study discusses how the identification of NTS, a major step for developing an NTS training program, might be re-interpreted from the perspective of resilience engineering (RE). This discussion is based on a case study of identifying NTS for electricians who perform emergency maintenance activities in an electricity distribution power line. The results of the case study point out that four data analysis procedures might operationalize the RE perspective: (a) identifying factors that make the work difficult and which could be integrated into NTS training scenarios; (b) identifying recommendations for re-designing the system, in order either to reduce or eliminate the need for NTS; (c) classifying the NTS into pragmatic categories, which are meaningful for workers; and (d) regarding the identification of NTS as an opportunity to give visibility to adaptations carried out by workers.

    Full Text Available This study reports the results of an investigation into the technical efficiency of citrus farmers of Sargodha District of Punjab Province. The method employed was the stochastic frontier production function approach suggested by Battese and Coelli (1995 for cross sectional data. The model was estimated by using the data on 82 citrus farmers for the period 2008. The coefficients of the production function revealed that the use of more water and nitrogen by the farmers involved in intercropping reduced citrus output. The estimates of technical efficiencies of the farmers range from 0.53 to 0.98 while the mean technical efficiency was 0.88. This suggests that 12 % of citrus output forgoes because of inefficiency. Quality of inputs like water and land were found to be significant determinants of technical efficiency of the citrus farmers.

    Duke Energy performed a phase 1 study to assess the impact of offshore wind development in the waters off the coasts of North Carolina and South Carolina. The study analyzed the impacts to the Duke Energy Carolinas electric power system of multiple wind deployment scenarios. Focusing on an integrated utility system in the Carolinas provided a unique opportunity to assess the impacts of offshore wind development in a region that has received less attention regarding renewables than others in the US. North Carolina is the only state in the Southeastern United States that currently has a renewable portfolio standard (RPS) which requires that 12.5% of the state’s total energy requirements be met with renewable resources by 2021. 12.5% of the state’s total energy requirements in 2021 equates to approximately 17,000 GWH of energy needed from renewable resources. Wind resources represent one of the ways to potentially meet this requirement. The study builds upon and augments ongoing work, including a study by UNC to identify potential wind development sites and the analysis of impacts to the regional transmission system performed by the NCTPC, an Order 890 planning entity of which DEC is a member. Furthermore, because the region does not have an independent system operator (ISO) or regional transmission organization (RTO), the study will provide additional information unique to non-RTO/ISO systems. The Phase 2 study builds on the results of Phase 1 and investigates the dynamic stability of the electrical network in Task 4, the operating characteristics of the wind turbines as they impact operating reserve requirements of the DEC utility in Task 5, and the production cost of integrating the offshore wind resources into the DEC generation fleet making comparisons to future planned operation without the addition of the wind resources in Task 6.

In the agricultural sector, gender differential could influence the sourcing and efficient utilization of factors of production, particularly in the livestock sub-sector of the economy. This study assessed the gender differentials in economic and technical efficiency of poultry eggs production in Lagos State, Nigeria. Multistage sampling technique was used to select respondent poultry farmers. The first and second stages were the purposive selection of five Local Government Areas (LGAs reputed for poultry production and farm settlements in the state. The third stage involved a simple random sampling of 150 poultry farms consisting of 75 farms each managed by a male and a female Stochastic Frontier Analysis (SFA. The SFA revealed that for male management of poultry egg farms, labour input (p<0.01 and cost of medications (p<0.05 increased the poultry egg output. On the other hand, for female management, stock of birds (p<0.01, labour input (p<0.01 and feed cost (p<0.01 were the factors that increased poultry eggs output. The inefficiency model revealed that male farmers were more technically efficient (p<0.01 than female counterparts. Female managed poultry farms had less productivity (0.90 compared to males(1.22. However, 88.1% of male farms compared to 86.7% of female farms had economic efficiency ratios between 0.29 and 0.79. The study concluded that gender had impact on poultry farmers’ efficiency in the study area. The study therefore recommended that training should be organised for female managed farms while male managed farms should utilize less of cost intensive capital input.

    Technical skills are one of the attributes, an engineering student must attain by the time of graduation, as per recommended by Engineering Accreditation Council (EAC). This paper describes the development of technical skills, Programme Outcome (PO) number 5, in students taking the Bachelor of Electrical Power Engineering (BEPE) programme in Universiti Tenaga Nasional (UNITEN). Seven courses are identified to address the technical skills development. The course outcomes (CO) of the courses are designed to instill the relevant technical skills with suitable laboratory activities. Formative and summative assessments are carried out to gauge students’ acquisition of the skills. Finally, to measure the attainment of the technical skills, key course concept is used. The concept has been implemented since 2013, focusing on improvement of the programme instead of the cohort. From the PO attainment analysis method, three different levels of PO attainment can be calculated: from the programme level, down to the course and student levels. In this paper, the attainment of the courses mapped to PO5 is measured. It is shown that Power Electronics course, which is the key course for PO5, has a strong attainment at above 90%. PO5 of other six courses are also achieved. As a conclusion, by embracing outcome-based education (OBE), the BEPE programme has a sound method to develop technical psychomotor skills in the degree students.

    When the field of modern publishing was on a collision course with telecommunications, publishing organizations had to come up to speed in fields that were, heretofore, completely foreign and technologically forbidding to them. For generations, the technology of publishing centered on offset lithography, typesetting, and photography--fields that saw evolutionary and incremental change from the time of Guttenberg. But publishing now includes making information available over the World Wide Web--Internet publishing--with its ever-accelerating rate of technological change and dependence on computers and networks. Clearly, we need a methodology to help anyone in the field of Internet publishing plan for the future, and there is a well-known, well-tested technique for just this purpose--Scenario Planning. Scenario Planning is an excellent tool to help organizations make better decisions in the present based on what they identify as possible and plausible scenarios of the future. Never was decision making more difficult or more crucial than during the years of this study, 1996-1999. This thesis takes the position that, by applying Scenario Planning, the Technical Information Department at LLNL, a large government laboratory (and organizations similar to it), could be confident that moving into the telecommunications business of Internet publishing stood a very good chance of success.

    The production of technical snow today is a self-evident feature of modern alpine skiing resort management. Millions of Euros are invested every year for the technical infrastructure and its operation to produce a homogeneous and continuing snow cover on the skiing slopes for the winter season in almost every larger destination in the Alps. In Austria, skiing tourism is a significant factor of the national economic structure. We present the framing conditions of technical snow production in the mid-size skiing resort of Mayrhofen (Zillertal Alps/Austria, 136 km slopes, elevation range 630 - 2.500 m a.s.l.). Production conditions are defined by the availability of water, the planned date for the season opening, and the climatic conditions in the weeks before. By means of an adapted snow production strategy an attempt is made to ecologically and economically optimize the use of water and energy resources. Monitoring of the snow cover is supported by a network of low-cost sensors and mobile snow depth recordings. Finally, technical snow production is simulated with the spatially distributed, physically based hydroclimatological model AMUNDSEN. The model explicitly considers individual snow guns and distributes the produced snow along the slopes. The amount of simulated snow produced by each device is a function of its type, of actual wet-bulb temperature at the location, of ski area infrastructure (in terms of water supply and pumping capacity), and of snow demand.

    The challenges faced by the developing countries are unique in that they need to meet the increasing energy demands for their economic growths at a competitive price without damaging the environments. In this paper, a case study on the electricity demand issue in Sabah, Malaysia, is presented to investigate potential solutions in addressing this current need for a typical developing economy from the technical, economical and environmental perspectives. Sabah, one of the 13 states in Malaysia, is currently experiencing a serious power shortage, especially at the east coast. A 300 MW coal plant is proposed by the electricity utility company. However, the proposal has been rejected in the past several years due to the negative environmental impacts of the plant. In this paper, a number of alternative solutions were evaluated and proposed with respect to the viability of technologies, financial return and minimum environmental impact in terms of GHG emission.

    Accurate prediction of groundwater table is important for the efficient management of groundwater resources. Despite being the most widely used tools for depicting the hydrological regime, numerical models suffer from formidable constraints, such as extensive data demanding, high computational cost, and inevitable parameter uncertainty. Artificial neural networks (ANNs), in contrast, can make predictions on the basis of more easily accessible variables, rather than requiring explicit characterization of the physical systems and prior knowledge of the physical parameters. This study applies ANN to predict the groundwater table in a freshwater swamp forest of Singapore. The inputs to the network are solely the surrounding reservoir levels and rainfall. The results reveal that ANN is able to produce an accurate forecast with a leading time of 1 day, whereas the performance decreases when leading time increases to 3 and 7 days.

    2013-12-01

    Full Text Available Drowned in explosive amounts of information, new technology developments, globalisation, international job opportunities and large-scale job migration, ESP courses are faced with the increasing requirement of tailoring language-learning to accommodate employer/employee specialisations. This dynamism is currently being transmitted to courses at the university level, along with the accompanying challenges for all involved. This paper reviews these potential barriers to implementation of ESP courses for students with low proficiency of English, taking a pre-intermediate-level Technical English course at the Czech University of Life Sciences Prague as a case study. After analysing various scholarly references aimed at ESP, the classroom-based research for this paper confirms the feasibility and efficacy of implementing ESP and TE, in particular, even into pre-intermediate classrooms. The self-motivating design of 6 TASKS, as well as authentic video sessions, combined with a student survey and teacher observations, all serve to point to ESP introduction on the pre-intermediate level as achievable in terms of application and resourceful regarding future life-career situations in which students will eventually find themselves.

    Case of different sizes and shapes for teaching technical writing to engineers at Wayne State University have been developed. The case approach was adopted for some assignments because sophomores and juniors lacked technical expertise and professional knowledge of the engineering world. Cases were found to be good exercises, providing realistic practice in specific writing tasks or isolating particular skills in the composing process. A special kind of case which narrates the experiences of one technical person engaged in the problem-solving process in a professional rhetorical situation was developed. This type of long, realistic fiction is called a an "holistic" case. Rather than asking students to role-play a character, an holistic case realistically encompasses the whole of the technical writing process. It allows students to experience the total communication act in which the technical task and data are fully integrated into the rhetorical situation and gives an opportunity to perform in a realistic context, using skills and knowledge required in communication on the job. It is believed that the holistic case most fully exploits the advantages of the case method for students of professional communication.

    In November 2008, a technical guidance document on the challenge test protocol was published by the EU CRL (Community of Reference Laboratory) for L. monocytogenes. This document describes the practical aspects on the execution of a challenge test in order to comply to the EU Commission regulation N° 2073/2005 on microbiological criteria for foodstuff. In this guideline two approaches are specified. On the one hand challenge tests, based on actual data measurements at the beginning and end of the shelf-life of products stored under reasonably foreseen T-profile, are described. On the other hand, growth potential is calculated by predictive models using a validated maximum specific growth rate. The present study evaluates the two above mentioned approaches on cold smoked salmon, a typical risk product for L. monocytogenes. The focus is on: (i) the relative importance of intrabatch versus interbatch variability, (ii) the concept of a simple challenge test based on actual data at start and end of shelf life versus a modelling approach and (iii) the interpretation of challenge tests. Next to this, available tertiary models were used to estimate the growth potential of these products based on their initial physicochemical characteristics. From the results it could be concluded that in some batches considerable intrabatch variability was obtained. In general, however, the interbatch variability was significantly higher than intrabatch variability. Concerning the two above mentioned methods for challenge tests, it can be stated that the first approach (simple challenge test) can be set up rather rapidly and is cost-effective for SMEs (small and medium enterprises) but provides only a single isolated outcome. This implies that challenge tests should be redone if changes occur in composition or production process. The second (modelling) approach, using extended challenge tests to establish growth parameters needs larger set ups and more complicated data analysis, which

    2017-06-01

    Custom tailors working in the informal sector in Nairobi, Kenya, mainly acquire technical skills through undertaking traditional apprenticeships (TAs). However, most of these tailors are semi-skilled, produce low-quality products and are often poorer than their formally trained counterparts. This qualitative case study explores the aspects of technical skills and knowledge which tailoring apprentices develop, and the factors which influence these outcomes. The findings show that apprentices do acquire basic technical skills for immediate application to ongoing tailoring activities (such as how to take body measurements, draft patterns, and cut, sew and finish constructed garments). However, apprentices do not acquire the technical knowledge that underpins the trade. Most master tailors who have completed TAs lack technical knowledge and have no access to technical skills upgrading. This perpetuates the cycle of basic and limited technical skills transfer to apprentices, poor performance and poverty among tailors. Both apprentices and master tailors expressed concern over knowledge limitations in TAs and a need to access further training to improve skills and acquire knowledge of the trade. The authors of this article argue that, technically and pedagogically, skilled master tailors are critical to improving training quality. Complementary training in theoretical knowledge is also important in improving apprentices' technical skills and understanding of the trade. Inclusion of TAs in government policy may help ensure sustainable improvement of skills.

    Full Text Available The effective production of high-quality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of high-quality anthracite. Six key steps were explored, including coal falling at the coalface, transport, underground bunker storage, main shaft hoisting, coal preparation on the ground, and railway wagon loading. The study resulted in optimized running parameters for the shearers, and the rotating patterns of the shearer drums was altered (one-way cutting was employed. Mining height and roof supporting intensity were reduced. Besides, loose presplitting millisecond blasting and mechanized mining were applied to upgrade the coal quantity and the lump coal production rate. Additionally, the coalface end transloading, coalface crush, transport systems, underground storage, and main shaft skip unloading processes were improved, and fragmentation-prevention techniques were used in the washing and railway wagon loading processes. As a result, the lump coal production rate was maintained at a high level and fragmentation was significantly reduced. Because of using the parameters and techniques determined in this research, high-quality coal production and increased profits were achieved. The research results could provide theoretical guidance and methodology for other anthracite production bases.

    2017-09-04

    The Nix Pro Colour Sensor™ (NIX) can be potentially used to measure meat colour, but procedural guidelines that assure measurement reproducibility and repeatability (precision) must first be established. Technical replicate number (r) will minimise response variation, measureable as standard error of predicted mean (SEM), and contribute to improved precision. Consequently, we aimed to explore the effects of r on NIX precision when measuring aged beef colour (colorimetrics; L*, a*, b*, hue and chroma values). Each colorimetric SEM declined with increasing r to indicate improved precision and followed a diminishing rate of improvement that allowed us to recommend r=7 for meat colour studies using the NIX. This definition was based on practical limitations and a* variability, as additional r would be required if other colorimetrics or advanced levels of precision are necessary. Beef ageing and display period, holding temperature, loin and sampled portion were also found to contribute to colorimetric variation, but were incorporated within our definition of r.

    2013-01-01

    Full Text Available Abstract Background Language comprehension requires decoding of complex, rapidly changing speech streams. Detecting changes of frequency modulation (FM within speech is hypothesized as essential for accurate phoneme detection, and thus, for spoken word comprehension. Despite past demonstration of FM auditory evoked response (FMAER utility in language disorder investigations, it is seldom utilized clinically. This report's purpose is to facilitate clinical use by explaining analytic pitfalls, demonstrating sites of cortical origin, and illustrating potential utility. Results FMAERs collected from children with language disorders, including Developmental Dysphasia, Landau-Kleffner syndrome (LKS, and autism spectrum disorder (ASD and also normal controls - utilizing multi-channel reference-free recordings assisted by discrete source analysis - provided demonstratrions of cortical origin and examples of clinical utility. Recordings from inpatient epileptics with indwelling cortical electrodes provided direct assessment of FMAER origin. The FMAER is shown to normally arise from bilateral posterior superior temporal gyri and immediate temporal lobe surround. Childhood language disorders associated with prominent receptive deficits demonstrate absent left or bilateral FMAER temporal lobe responses. When receptive language is spared, the FMAER may remain present bilaterally. Analyses based upon mastoid or ear reference electrodes are shown to result in erroneous conclusions. Serial FMAER studies may dynamically track status of underlying language processing in LKS. FMAERs in ASD with language impairment may be normal or abnormal. Cortical FMAERs can locate language cortex when conventional cortical stimulation does not. Conclusion The FMAER measures the processing by the superior temporal gyri and adjacent cortex of rapid frequency modulation within an auditory stream. Clinical disorders associated with receptive deficits are shown to demonstrate absent

    2017-05-01

    Crude palm oil produced in Indonesia has already been known as the largest in the world. Unfortunately many of palm oil factories (CPOF) spread out in Indonesia have not good wastewater treatments (WWTP) yet. PT Socfin Indonesia, as an example, which is located in Aceh Tamiang Regency, still has BOD contained in its final effluent of the waswater treatment plant more than 150 ppm. In fact, the capability and capacity of WWTP in PT Socfin are 192 m3per day. Because of improper operational and maintenance of the WWTP, the technical prob lem are accumulated, such as, increasing the deposition of sludge and decreasing the retention time. The following affect is the treatment process is not going well and the quality of effluent is getting worse. The objective of this paper is to solve the technical problems by means remov ing the deposition of sludge periodically and fixing floating aeration in the aerobic pond. Method using for this paper is survey and wastewater sampling. A recommendation of the was tewater treatment system has been proposed after average BOD from WWTP outlet is defined 158 mg/L. The recommendation has seven procesess including oil separation, neutralization, closed tank anaerobic digester equipped with gas holder, extended aeration, settling tank, sand drying bed and land application.

    2015-03-01

    Full Text Available The low average single-well production, resulting in low economic benefit, has become the main bottleneck of CBM development in China. In view of this issue, through case study of a CBM gas reservoir in the southern Qinshui Basin, we summarized the present status of CBM technology and development there and also pointed out some major problems in CBM development: (1 the engineering technology for the CBM development needs to adapt to the particular geological characteristics; (2 a large number of inefficient zones still exist in mature blocks in the southern Qinshui Basin; (3 single-well production can not be effectively enhanced only by increasing the fracturing scale; (4 the production of multi-lateral wells is higher, but the fulfillment rate of production capacity overall is still low; and (5 on-site management lacks scientific evidence. On this basis, we present the following suggestions for subsequent coalbed gas development: (1 the production construction mode should be changed, and the fulfillment rate of production capacity construction should be improved; (2 CBM geological research should be improved and well types and locations should be designed reasonably and scientifically; (3 main technologies should be built in a dialectical thinking mode; (4 horizontal well design should be optimized to improve the applicability of relevant technologies; (5 fracturing mode should be changed to improve single-well production; and (6 the drainage technology should be changed to improve economic efficiency.

    This paper describes a technical feasibility study on the application of polycarbonate (PC) plates in a superstrate photovoltaic module design. The lamination process was performed in a conventional laminator apparatus using low temperature curing (100{sup o}C) ethylene-vinyl-acetate (EVA) as the potting material and multi-crystalline silicon-solar cells. Thermo-mechanical calculations via the finite element method were performed to support the experimental results on various layer set-ups. Both experimental and numerical results revealed that PC superstrate laminates display a certain degree of warpage after the lamination process. This warpage can be attributed to stress built up in the modules due to differences in thermal expansion between solar cells and PC. This stress build-up can be diminished by application of thicker layers of PC or EVA leading to less curved laminates. (author)

  15. A case study review of technical and technology issues for transition of a utility load management program to provide system reliability resources in restructured electricity markets

    Weller, G.H.

    2001-07-15

    Utility load management programs--including direct load control and interruptible load programs--were employed by utilities in the past as system reliability resources. With electricity industry restructuring, the context for these programs has changed; the market that was once controlled by vertically integrated utilities has become competitive, raising the question: can existing load management programs be modified so that they can effectively participate in competitive energy markets? In the short run, modified and/or improved operation of load management programs may be the most effective form of demand-side response available to the electricity system today. However, in light of recent technological advances in metering, communication, and load control, utility load management programs must be carefully reviewed in order to determine appropriate investments to support this transition. This report investigates the feasibility of and options for modifying an existing utility load management system so that it might provide reliability services (i.e. ancillary services) in the competitive markets that have resulted from electricity industry restructuring. The report is a case study of Southern California Edison's (SCE) load management programs. SCE was chosen because it operates one of the largest load management programs in the country and it operates them within a competitive wholesale electricity market. The report describes a wide range of existing and soon-to-be-available communication, control, and metering technologies that could be used to facilitate the evolution of SCE's load management programs and systems to provision of reliability services. The fundamental finding of this report is that, with modifications, SCE's load management infrastructure could be transitioned to provide critical ancillary services in competitive electricity markets, employing currently or soon-to-be available load control technologies.

    2015-04-15

    Purpose: The imaging of positron emitting isotopes produced during patient irradiation is the only in vivo method used for hadrontherapy dose monitoring in clinics nowadays. However, the accuracy of this method is limited by the loss of signal due to the metabolic decay processes (biological washout). In this work, a generic modeling of washout was incorporated into the GATE simulation platform. Additionally, the influence of the washout on the β{sup +} activity distributions in terms of absolute quantification and spatial distribution was studied. Methods: First, the irradiation of a human head phantom with a {sup 12}C beam, so that a homogeneous dose distribution was achieved in the tumor, was simulated. The generated {sup 11}C and {sup 15}O distribution maps were used as β{sup +} sources in a second simulation, where the PET scanner was modeled following a detailed Monte Carlo approach. The activity distributions obtained in the presence and absence of washout processes for several clinical situations were compared. Results: Results show that activity values are highly reduced (by a factor of 2) in the presence of washout. These processes have a significant influence on the shape of the PET distributions. Differences in the distal activity falloff position of 4 mm are observed for a tumor dose deposition of 1 Gy (T{sub ini} = 0 min). However, in the case of high doses (3 Gy), the washout processes do not have a large effect on the position of the distal activity falloff (differences lower than 1 mm). The important role of the tumor washout parameters on the activity quantification was also evaluated. Conclusions: With this implementation, GATE/GEANT 4 is the only open-source code able to simulate the full chain from the hadrontherapy irradiation to the PET dose monitoring including biological effects. Results show the strong impact of the washout processes, indicating that the development of better models and measurement of biological washout data are

    Full Text Available This research characterizes four samples of recycled aggregate for their potential use in road construction projects in consonance with the Spanish General Technical Specifications for Roads and Bridge Works (PG-3. Although some fractions were of sufficient quality for the construction of embankments, backfills, and quarry-run fills, they were ultimately found to be unsuitable for the construction of underground drainage, granular structural layers, soil stabilization and concrete pavements. They were negatively evaluated because of their particle size distribution and sulfate content. Nevertheless, the quality of this recycled aggregate could be substantially improved by manually removing the gypsum before the crushing process at the plant or by selecting the material with greater care at the beginning of the process. Finally, we suggest that Construction and Demolition (C&D waste plant managers should modify the manufacturing process to obtain a suitable particle size distribution in accordance with PG-3 requirements and the projected use of the aggregate.

  7. Dioxin: a case study.

    Science.gov (United States)

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    在市场经济条件下西藏经济迅速发展,民族手工业等特色产业逐渐壮大,大量研究揭示民族手工业发展与市场之间的密切关系。西藏藏毯企业在外部环境与青海藏毯企业日益趋同的情况下仍存在巨大差异,需要从企业内部微观层面诠释深层次原因。文章以企业创新理论为基础,在综合现有的技术创新影响因素的基础上构建西藏藏毯企业技术创新影响模型,选择4家具有代表性的藏毯企业进行案例研究。发现现有研究揭示的技术创新影响因素并不都适用于藏毯企业,突出表现在内部受技术创新能力和激励机制的影响,外部受市场需求、市场竞争程度以及政府支持力度的影响,进一步研究发现技术创新与企业业绩之间受到技术因素和非技术因素协同程度的调节。%Under market economy, Tibet's economy develops rapidly. And the featured industries in Tibet, such as ethnic handicrafts, grow gradually, too. Numerous studies reveal a close relationship between ethnic handi⁃crafts’development and the market. The external environment of Qinghai’s and Tibetan carpet business be⁃comes more and more convergent, but there are still huge differences between Tibetan carpet business in Qinghai and Tibet, which needs high-level interpretation and micro-level analysis of the enterprises. Basing on the Enter⁃prise Innovation Theory, this article integrates the existing influential factors of technological innovation so as to construct an influential model of the technological innovation for Tibetan carpet. And 4 typical Tibetan carpet en⁃terprises are selected as study cases, the study shows that not all the existing influential factors about technical innovation research is applicable for the Tibetan carpet enterprises. Internally, the Tibetan carpet enterprises could be affected by the technological innovation and the incentive mechanism. Externallly, they could be

  12. Exploring technical and cultural appeals in strategic risk communication: the Fernald radium case.

    Science.gov (United States)

    Hamilton, Jennifer Duffield

    2003-04-01

    Risk disputes are often characterized by tensions between technical and cultural understandings of risk and by communication practices that reflect those differing perspectives. This study considers how participants in risk debates draw upon and combine aspects of technical and cultural rationality as broad orientations to risk in expressing their views and formulating persuasive appeals during risk debates. Rhetorical theorist Kenneth Burke's (1984) concept of frames of acceptance is used to analyze a case study involving competing priorities for radium stored at the Fernald site, a former Department of Energy nuclear weapons facility. A rhetorical analysis is conducted using the transcript from a 1995 public meeting during which local residents and a nuclear medicine expert discussed priorities of Fernald site cleanup versus providing radium stored on site for promising cancer research. Two tensions are identified that fostered disagreement among discussants: the first a tension between a local or global context for the controversy and the second a tension between competing definitions of public participation for this issue. This study analyzes the rhetorical strategies by which participants in the Fernald radium debate articulated these tensions and argues that technical and cultural rationality (Plough & Krimsky, 1987) acted as sources of rhetorical invention influencing participants' individual frames of acceptance and the ways they defined and interpreted the situation and crafted persuasive appeals.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

  15. Study of job burnout in technical writers and technical illustrators/designers at LLNL

    Energy Technology Data Exchange (ETDEWEB)

    Rice, J A

    1998-06-03

    According to the American Institute of Stress, job stress is estimated to cost American industry more than $200 billion a year. These costs are, in part, related to the estimated 1 million employees that will be absent on an average workday because of stress; 75 percent of visits to primary care physicians are for stress-related problems. California workers' compensation claims for stress cost $1 billion for medical and legal fees alone (Murphy, 1997). But, there is another dimension to stress that needs to be addressed. Job stress can be a precursor to job burnout. Burnout is a loss of motivation, and antidotes for job stress will not necessarily alleviate or stop job burnout. Job burnout is experienced as exhaustion on physical, emotional, and cognitive levels. Burnout can include withdrawal and decreasing involvement on the job, seriously affecting job satisfaction, turnover, absenteeism, and productivity (Dwyer & Ganster, 1991; Erickson & Gunderson, 1972; Spector & Jex, 1991). The research project described in this paper examined whether job burnout exists in the technical writer and technical illustrator/designer occupations in the Technical Information Department at Lawrence Livermore National Laboratory. This study also determined at what age and after how many years of service these employees were most likely to experience job burnout, whether it affects men or women most, and if writers in a technical organization experience job burnout more than illustrators/designers in that organization.

    Full Text Available We present a 60-year old woman with recurrent cervical adenocarcinoma who presented with metastasis to both lungs and to her right adrenal gland. A thoracotomy was performed for resection of her pulmonary metastasis and then the right adrenal gland was excised through a trans-diaphragmatic approach. The adrenal gland resection was more complex due to involvement of the tumor with the inferior vena cava (IVC which was repaired with a PTFE patch graft. This case demonstrates both an interesting approach to surgical resection of multiple metastases as well as a safe, although more challenging, alternative to partially resect and repair the IVC.

    The Division of Solar Technology of the Department of Energy is currently examining the market potential of a number of dispersed solar energy systems, including the small (less than or equal to 10 MW/sub e/) solar thermal power system. Small fossil-fueled generating units in the United States utility system, (i.e., investor-owned, municipal, and cooperatives) have a current capacity of approximately 8000 MW/sub e/ or about 1.5 percent of the total US electrical capacity, and provide a large potential market for small solar thermal power systems. The Small Power Systems Study has as its objective the determination of conditions under which small (less than or equal to 10 MW/sub e/) solar thermal power units can provide cost-effective electrical power to a variety of users. Potential users, in addition to the utility systems; include Department of Defense installations and applications, remote mining and/or lumbering operations, and other industrial power systems with and without cogeneration. The first year's results on the Small Power Systems Study are summarized. The data base used and the breakeven cost analysis are discussed. Information on both small (less than or equal to 10 MW/sub e/) generating units and the utility systems using them is presented as well as data on fossil fuel costs, solar plant costs, and solar insolation values. The results of a survey of Department of Defense (DOD) worldwide electrical generating capacity at its military bases and on a potential DOD application are presented. Information on a potential small solar power system experiment in the interior of Alaska is given, and a limited amount of information on a remote application which would provide power or a large open pit copper mine is presented. Volume II of this Technical Summary Report contains an inventory, by state, of the small (less than or equal to 10 MW/sub e/) generating units in the US utility system. (WHK)

  15. Economic and technical feasibility study of compressed air storage

    Energy Technology Data Exchange (ETDEWEB)

    1976-03-01

    The results of a study of the economic and technical feasibility of compressed air energy storage (CAES) are presented. The study, which concentrated primarily on the application of underground air storage with combustion turbines, consisted of two phases. In the first phase a general assessment of the technical alternatives, economic characteristics and the institutional constraints associated with underground storage of compressed air for utility peaking application was carried out. The goal of this assessment was to identify potential barrier problems and to define the incentive for the implementation of compressed air storage. In the second phase, the general conclusions of the assessment were tested by carrying out the conceptual design of a CAES plant at two specific sites, and a program of further work indicated by the assessment study was formulated. The conceptual design of a CAES plant employing storage in an aquifer and that of a plant employing storage in a conventionally excavated cavern employing a water leg to maintain constant pressure are shown. Recommendations for further work, as well as directions of future turbo-machinery development, are made. It is concluded that compressed air storage is technically feasible for off-peak energy storage, and, depending on site conditions, CAES plants may be favored over simple cycle turbine plants to meet peak demands.

    The AECL study for an intense neutron-generator has been in progress for two years. Recently the scientific and technical details and the conceptual designs were compiled in a report supporting proposals addressed to AECL's Board of Directors for further work. The compilation is being issued in this form to permit further discussion of the technical aspects. However readers are asked to appreciate that it was written primarily for an AECL audience, and specifically that those chapters giving tentative information about costs, the rate of investment and similar items have been omitted or modified, many references have been made to interim internal reports in order to complete the local documentation, but these references do not imply that the reports themselves can be made generally available.

    2016-08-26

    A simulation-based technical feasibility study was completed to show the types of technologies required to achieve ZEB status with this building type. These technologies are prioritized across the building's subsystem such that design teams can readily integrate the ideas. Energy use intensity (EUI) targets were established for U.S. climate zones such that K-12 schools can be zero-ready or can procure solar panels or other renewable energy production sources to meet the zero energy building definition. Results showed that it is possible for K-12 schools to achieve zero energy when the EUI is between 20 and 26 kBtu/ft2/yr. Temperate climates required a smaller percentage of solar panel coverage than very hot or very cold climates. The paper provides a foundation for technically achieving zero energy schools with a vision of transforming the school construction market to mainstream zero energy buildings within typical construction budgets.

  18. A phenomenographic study of the ability to address complex socio-technical systems via variation theory

    Science.gov (United States)

    Mendoza Garcia, John A.

    Sometimes engineers fail when addressing the inherent complexity of socio-technical systems because they lack the ability to address the complexity of socio-technical systems. Teaching undergraduate engineering students how to address complex socio-technical systems, has been an educational endeavor at different levels ranging from kindergarten to post-graduate education. The literature presents different pedagogical strategies and content to reach this goal. However, there are no existing empirically-based assessments guided by a learning theory. This may be because at the same time explanations of how the skill is developed are scarce. My study bridges this gap, and I propose a developmental path for the ability to address the complex socio-technical systems via Variation Theory, and according to the conceptual framework provided by Variation Theory, my research question was "What are the various ways in which engineers address complex socio-technical systems?" I chose the research approach of phenomenography to answer my research question. I also chose to use a blended approach, Marton's approach for finding the dimensions of variation, and the developmental approach (Australian) for finding a hierarchical relationship between the dimensions. Accordingly, I recruited 25 participants with different levels of experience with addressing complex socio-technical systems and asked them all to address the same two tasks: A design of a system for a county, and a case study in a manufacturing firm. My outcome space is a nona-dimensional (nine) developmental path for the ability to address the complexity in socio-technical systems, and I propose 9 different ways of experiencing the complexity of a socio-technical system. The findings of this study suggest that the critical aspects that are needed to address the complexity of socio-technical systems are: being aware of the use of models, the ecosystem around, start recognizing different boundaries, being aware of time as a

    Brainstem cavernous malformations are challenging due to the critical anatomy and potential surgical risks. Anterolateral, lateral, and dorsal surgical approaches provide limited ventral exposure of the brainstem. The authors present a case of a midline ventral pontine cavernous malformation resected through an endoscopic endonasal transclival approach based on minimal brainstem transection, negligible cranial nerve manipulation, and a straightforward trajectory. Technical and reconstruction technique advances in endoscopic endonasal skull base surgery provide a direct, safe, and effective corridor to the brainstem.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

    This project is to provide the regulatory direction of 4 major technical issues for the Korean Next Generation Reactors, which are parts of major technical issues resulted from the safety regulation R and D on the KNGR. The outstanding results are are as follows : related to the classification and acceptance criteria of plant conditions, currently used classification and safety requirement were reviewed and regulatory direction was proposed. Among multiple failures, it is identified that SBO, TLOFW, multiple SGTR and ATWS are basically to be considered for additional requirements for advanced reactors. This study reviewed risk aspects, design consideration, and trends of safety requirements, and proposed fundamental safety requirements to be applied for KNGR. Multiple steam generator tube failure is a significant safety concern because of the possibility of release of radionuclides to the environment through containment bypass. Proposed safety requirement for this event can be categorized mainly as analysis requirement, design evaluation requirement and PSA requirement; For protection of containment failure, a reasonable safety position is necessary through and integrated review of possibility of severe accident occurrence, effects of sever accident mitigation features and cost effects of these design features. With this consideration safety requirements developed are the analysis requirement, provision of protective measures and survivability/availability of protective measures.

    2016-09-01

    Full Text Available In the current study, we compared technical efficiency of smallholder rice farmers with and without credit in northern Ghana using data from a farm household survey. We fitted a stochastic frontier production function to input and output data to measure technical efficiency. We addressed self-selection into credit participation using propensity score matching and found that the mean efficiency did not differ between credit users and non-users. Credit-participating households had an efficiency of 63.0 percent compared to 61.7 percent for non-participants. The results indicate significant inefficiencies in production and thus a high scope for improving farmers’ technical efficiency through better use of available resources at the current level of technology. Apart from labour and capital, all the conventional farm inputs had a significant effect on rice production. The determinants of efficiency included the respondent’s age, sex, educational status, distance to the nearest market, herd ownership, access to irrigation and specialisation in rice production. From a policy perspective, we recommend that the credit should be channelled to farmers who demonstrate the need for it and show the commitment to improve their production through external financing. Such a screening mechanism will ensure that the credit goes to the right farmers who need it to improve their technical efficiency.

    This report is a part of the interim report documentation for the Global Spent Fuel Logistics System (GSFLS) study. The technical and financial considerations underlying a global spent fuel logistics systems have been studied and are reported. The Pacific Basin is used as a model throughout this report; however the stated methodology and, in many cases, considerations and conclusions are applicable to other global regions. Spent fuel discharge profiles for Pacific Basin Countries were used to determine the technical systems requirements for alternative concepts. Functional analyses and flows were generated to define both system design requirements and logistics parameters. A technology review was made to ascertain the state-of-the-art of relevant GSFLS technical systems. Modular GSFLS facility designs were developed using the information generated from the functional analysis and technology review. The modular facility designs were used as a basis for siting and cost estimates for various GSFLS alternatives. Various GSFLS concepts were analyzed from a financial and economic perspective in order to provide total concepts costs and ascertain financial and economic sensitivities to key GSFLS variations. Results of the study include quantification of GSFLS facility and hardware requirements; drawings of relevant GSFLS facility designs; system cost estimates; financial reports - including user service charges; and comparative analyses of various GSFLS alternatives.

    Acar, Maria Elizabeth Dias

    2015-07-01

    A methodology combining process mapping and analysis; knowledge elicitation mapping and critical analysis; and socio technical analysis based on social network analysis was conceived. The methodology was applied to a small knowledge intensive organization - LNMRI, and has allowed the appraisal of the main intellectual assets and their ability to evolve. In this sense, based on real issues such as attrition, the impacts of probable future scenarios were assessed. For such task, a multimodal network of processes, knowledge objects and people was analyzed using a set of appropriate metrics and means, including sphere of influence of key nodes. To differentiate the ability of people's role playing in the processes, some nodes' attributes were used to provide partition criteria for the network and thus the ability to differentiate the impact of potential loss of supervisors and operators. The proposed methodology has allowed for: 1) the identification of knowledge objects and their sources; 2) mapping and ranking of these objects according to their relevance and 3) the assessment of vulnerabilities in LNMRI's network structure and 4) revealing of informal mechanisms of knowledge sharing The conceived methodological framework has proved to be a robust tool for a broad diagnosis to support succession planning and also the organizational strategic planning.

    This study was conducted to search for the type of technical error in DEXA (dual-energy X-ray absorptiometry) and the effect of error to measurement of BMD. The changes of BMD (g/cm{sup 2}, T-score) by patients information (Age, Weight, Height, Manopause age) input error and Confirming ROI error were investigated. Using spine phantom, we canned 10 times by age (5, 10), weight (10, 20 kg), height (5, 10 cm), manopause age (5, 10) increase and decrease respectively. Scanning region (L-spine, femur, Forearm) of 10 patients was calculated by changing ROI respectively. Analysis of difference for mean (precision 1%) were carried out. There error of patient information (Age, Weight, Height, Manopause age) was not changed differently. In confirming ROI, the BMD and T-score of L-spine involving T-12 was decreased to 0.063 g/cm{sup 2}, 0.3 and involving L-5 increased to 0.077 g/cm{sup 2}, 0.5. In narrowing 1 cm of vertical line of ROI, the BMD and T-score decreased to 0.006 g/cm{sup 2}, 0.1 and in 2 cm, 0.021 g/cm{sup 2}, 0.15, each. In hip ROI, Upper and left shift (0.5 cm) of line was not influenced BMD and T-score. In 0.5 cm lower shift (lesser trochanter below), the BMD and T-score increased 0.031 g/cm{sup 2}, 0.3 and in 1 cm 0.094 g/cm{sup 2}, 0.65, each. In forearm ROI, the BMD and T-score decreased 0.042 g/cm{sup 2}, 0.9 involving 1 cm lower wrist. And expanding 1 cm of vertical line, the BMD and T-score decreased 0.008 g/cm{sup 2}, 0.1 and in 2 cm, 0.021 g/cm{sup 2}, 0.3, each. The L-spine, hip, forearm ROI error was changed differently. There are so many kinds of technical error in BMD processing. Errors according to age, weight, height, manopause age did not influent to BMD (g/cm{sup 2}) and T-score. There are mean differences BMD and T-score in confirming ROI. For the precision exam, in L-spine processing, L1-4 have to confirmed without shift of ROI vertical line. In hip processing, the ROI have to included greater trochanter, femur head and lesser trochanter. In

Two different sets of 9 casings each will be progressively delivered, from 2013 to the end of 2015, to ASG Superconductors (Genoa, Italy) and to Alstom (Belfort, France), where the integration of the winding pack into the casing will be carried out. Each TF coil casing (height 7.5 m and width 4.5 m) consists of four main components: one “Straight Leg Outboard” and one “Curved Leg Outboard” both with their own covers, “Straight Leg Inboard” and “Curved Leg Inboard”. The casing components are segmented in forgings and plates made of FM316LNL. The straight leg outboard is composed of two wings welded to a central core and two elbows welded at the ends with a cooling channel installed inside. Elbows of straight leg outboard are segmented in two half-elbows machined from 1 rough forging and welded to the central core made by plate. Welding of wings to the central core is performed in EBW (electron beam welding) and the straight part is welded to the elbows by NGTIG (TIG narrow gap) process. The curved leg outboard is composed of two

    Resection of intradural tumors is often followed by bending of the spinal cord within the surgical cave. This event is known to be innocuous. The authors report a case where the position assumed by the spinal cord at the end of surgery was associated with significant motor evoked potential decline. The patient, a 44-year-old woman with a meningioma of the craniocervical junction, underwent tumor resection aided by intraoperative neurophysiological monitoring. At the time of dural closure, the motor evoked potentials were completely lost on the left side and reduced on the right side. Intraoperative maneuvers showed that worsening was related to the spinal cord position. Motor evoked potentials were restored by tethering the cord posteriorly, back to its original site. This report underlines the usefulness of maintaining intraoperative monitoring until the end of surgery and provides a technical nuance to manage a rare complication.

    The vitreous of three patients with asteroïd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroïd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroïd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroïd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroïd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS)

  1. The socio-technical organisation of community pharmacies as a factor in the Electronic Prescription Service Release Two implementation: a qualitative study

    Science.gov (United States)

    2012-01-01

    Background The introduction of a new method of transmitting prescriptions from general practices to community pharmacies in England (Electronic Prescription Service Release 2 (EPS2)) has generated debate on how it will change work practice. As EPS2 will be a key technical element in dispensing, we reviewed the literature to find that there were no studies on how social and technical elements come together to form work practice in community pharmacies. This means the debate has little point of reference. Our aim therefore was to study the ways social and technical elements of a community pharmacy are used to achieve dispensing through the development of a conceptual model on pharmacy work practice, and to consider how a core technical element such the EPS2 could change work practice. Method We used ethnographic methods inclusive of case-study observations and interviews to collect qualitative data from 15 community pharmacies that were in the process of adopting or were soon to adopt EPS2. We analysed the case studies thematically and used rigorous multi-dimensional and multi-disciplinary interpretive validation techniques to cross analyse findings. Results In practice, dispensing procedures were not designed to take into account variations in human and technical integration, and assumed that repetitive and collective use of socio-technical elements were at a constant. Variables such as availability of social and technical resources, and technical know-how of staff were not taken into account in formalised procedures. Yet community pharmacies were found to adapt their dispensing in relation to the balance of social and technical elements available, and how much of the social and technical elements they were willing to integrate into dispensing. While some integrated as few technical elements as possible, some depended entirely on technical artefacts. This pattern also applied to the social elements of dispensing.

    closed, from 7‐10 p.m. These shifts were covered by librarians working from home. Decisions to either begin or suspend services were generally made by small informal groups or committees. Some cases began with pilot studies and received positive responses. Other than these pilot studies, little pre‐planning appeared to have been done. For example, there were noextensive advance surveys or studies to determine potential demand or markets for the service, or projected costs and benefits. Only one service had a strong, multi‐stage evaluation plan. In future launches of virtual reference services, both extensive pre‐planning and detailed measures for evaluation could be helpful in avoidingsome problems. Major reasons for discontinuation fell into 6 categories: funding problems, staffing problems, technical problems, institutional culture conflicts, low usage overall or low usage by target populations. A table (Table 1 was included that actually listed 7 categories of reasons for discontinuation, but the last one listed, “Software Change,” is discussed as part of “Technical Problems” in the text, though it is separated in the table (527. This is not immediately clear in the article, and thus the table is slightly confusing. Four cases reported funding problems as the major reason for discontinuation. Low volume or low volume for target population were primary reasons for discontinuation by4 cases, and secondary reasons for discontinuation by 4 cases. If one combines primary and secondary categories in this table, low volume is the most frequently cited reason for discontinuation. Lowvolume was determined to be “driven by a complex combination of variables including marketing strategies, insufficient hours of operation, and [failure to provide] an ample amount of time for a service to gain momentum” (527‐528. Funding was cited as the primary reason for cancellation in 4 cases. Technical problems were listed as primary or secondary factors for suspension

    Full Text Available Waste generation is an inevitable by-product of human activity, and it is on the rise due to rapid urbanisation, industrialisation, increased wealth and population. The composition of municipal solid waste (MSW in developed and developing economies differ, especially with the organic fraction. Research shows that the food waste stream of MSW in developing countries is over 50%. The case study for this investigation, Nigeria, has minimal formal recycling or resource recovery programs. The average composition of waste from previous research in the country is between 50–70% putrescible and 30–50% non-putrescible, presenting significant resource recovery potential in composting and biogas production. Waste-to-energy (WtE is an important waste management solution that has been successfully implemented and operated in most developed economies. This contribution reports the conditions that would be of interest before WtE potentials of MSW is harnessed, in an efficient waste management process in a developing economy like Nigeria. The investigation presents a set of socio-technical parameters and transition strategy model that would inform a productive MSW management and resource recovery, in which WtE can be part of the solution. This model will find application in the understanding of the interactions between the socio-economic, technical and environmental system, to promote sustainable resource recovery programs in developing economies, among which is WtE.

    Full Text Available Imatinib –marketed as Gleevec™ or Glivec™– is a drug mainly used to treat a condition called Acute myeloid leukemia (AML. Its patent protection in Colombia, as a polymorphic entity of mesylate salt –called Beta polymorphous–, exhibits a divergent procedure due to differences between Colombian Patent Office (SIC and State Council judgment given in order to deny patent right in 2003 and then revoking such denial and ordering patent grant in 2012, respectively. This paper evaluates technical regards associated with each institution arguments and legal topics considered to conclude the instance. Findings show that studies carried out in relation to testimonial evidence and expert advice –that were submitted by two experts –one of them– directly related to the patent application– guided Colombian State Council in order to grant the polymorphous patent, even when there was no clear evidence of inventive step, especially referred as a compound surprising technical effect. Furthermore, the paper includes some comparisons related to legal instances that are in charge of studying patent office decisions in other jurisdictions and protection given –or not– to polymorphous entities in other countries.

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus...... on the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications for research...... design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes in a progressive...

    For the preparation of modern specialists in the acquisition and processing of three-dimensional data, a broad and detailed study of related modern methods and technologies is necessary. One of the most progressive and effective methods of acquisition and analyzing spatial data is terrestrial laser scanning. The study of methods and technologies for terrestrial laser scanning is of great importance not only for GIS specialists, but also for surveying engineers who make decisions in traditional engineering tasks (monitoring, executive surveys, etc.). The understanding and formation of the right approach in preparing new professionals need to develop a modern and variable educational program. This educational program must provide effective practical and laboratory work and the student's coursework. The resulting knowledge of the study should form the basis for practical or research of young engineers. In 2014, the Institute of Applied Sciences (Jade University Oldenburg, Germany) and Kyiv National University of Construction and Architecture (Kiev, Ukraine) had launched a joint educational project for the introduction of terrestrial laser scanning technology for collection and processing of spatial data. As a result of this project practical recommendations have been developed for the organization of educational processes in the use of terrestrial laser scanning. An advanced project-oriented educational program was developed which is presented in this paper. In order to demonstrate the effectiveness of the program a 3D model of the big and complex main campus of Kyiv National University of Construction and Architecture has been generated.

    Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

    The control of bulk coal is one of the important work of air pollution control in China’s future. Existing research mainly focuses on the adaptability, economy, construction and renovation plan, and operation optimization of specific energy substitution utilization, and lacks the strategy research of long-term layout of energy substitution utilization in large area. This paper puts forward a technical potential prediction method of coal to electricity based on the thermal equivalent method, which is based on the characteristics of regional coal consumption, and combined with the trend of adaptability and economy of energy substitution utilization. Also, the paper calculates the comprehensive benefit of coal to electricity according to the varieties of energy consumption and pollutant emission level of unit energy consumption in China’s future. The research result shows that the development technical potential of coal to electricity in China is huge, about 1.8 trillion kWh, including distributed electric heating, heat pump and electric heating boiler, mainly located in North China, East China, and Northeast China.

    Science.gov (United States)

    EPA announced the availability of the final report, Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen. This report is a starting point to determine what is known and what needs to be known about selected nanomaterials as part of a process to identify and prioritize research to inform future assessments of the potential ecological and health implications of these materials. Two specific applications of nanoscale titanium dioxide (nano-TiO2) are considered: (1) as an agent for removing arsenic from drinking water; and (2) as an active ingredient in topical sunscreen. These case studies are organized around a comprehensive environmental assessment (CEA) framework that combines a product life cycle perspective with the risk assessment paradigm. They are intended to help identify what may need to be known in order to conduct a comprehensive environmental assessment of the potential risks related to nano-TiO2. These “case studies” do not represent completed or even preliminary assessments, nor are they intended to serve as a basis for risk management decisions in the near term on these specific uses of nano TiO2. Rather, the intent is to use this document in developing the scientific and technical information needed for future assessment efforts.

    1975-01-01

    The authors report a new technique in arthrodesis of the sub-occipital spine which has been experienced since 1973 in case of metastases at CI-C2 level. An occipitovertebral metal plate, inverted Y shaped has been realised after anatomical and biomecanical studies. It is adapted to the occipito-vertebral curvature and screwed in the articular processes of C3 and C4 (14 mm screw), and in the pedicles of C2 (32 mm screw). At the upper part, the occiptal ridge offers fixation by 12 and 14 mm Muller's screw. In addition CI is attached to the plate, by a nylon thread. After the report of the first clinical case with a nine month period of follow up technical features of the material as well as practical problems are exposed. Tomograms of the cervical spine as well as bilateral brachial angiography are of paramount value. The latter investigation may reveal anomalies of the vertebral artery that can hinder of forbid the pedicular fixation. Finally the authors discuss the extension of this technique to complexe trauma of the suboccipital column.

    2015-12-01

    Full Text Available Purpose: Performance assessments of earthquake medical rapid response teams (EMRRTs, particularly the first responders deployed to the hardest hit areas following major earthquakes, should consider efficient and effective use of resources. This study assesses the daily technical efficiency of EMRRTs in the emergency period immediately following the 2010 Yushu earthquake in China. Methods: Data on EMRRTs were obtained from official daily reports of the general headquarters for Yushu earthquake relief, the emergency office of the National Ministry of Health, and the Health Department of Qinghai Province, for a sample of data on 15 EMRRTs over 62 days. Data envelopment analysis was used to examine the technical efficiency in a constant returns to scale model, a variable returns to scale model, and the scale efficiency of EMRRTs. Tobit regression was applied to analyze the effects of corresponding influencing factors. Results: The average technical efficiency scores under constant returns to scale, variable returns to scale, and the scale efficiency scores of the 62 units of analysis were 77.95%, 89.00%, and 87.47%, respectively. The staff-to-bed ratio was significantly related to global technical efficiency. The date of rescue was significantly related to pure technical efficiency. The type of institution to which an EMRRT belonged and the staff-to-bed ratio were significantly related to scale efficiency. Conclusions: This study provides evidence that supports improvements to EMRRT efficiency and serves as a reference for earthquake emergency medical rapid assistance leaders and teams.

    Commercially available solar collectors have the potential to provide a large fraction of the energy consumed for industrial process heat (IPH). Detailed case studies of individual industrial plants are required in order to make an accurate assessment of the technical and economic feasibility of applications. This report documents the results of seven such case studies. The objectives of the case study program are to determine the near-term feasibility of solar IPH in selected industries, identify energy conservation measures, identify conditions of IPH systems that affect solar applications, test SERI's IPH analysis software (PROSYS/ECONOMAT), disseminate information to the industrial community, and provide inputs to the SERI research program. The detailed results from the case studies are presented. Although few near-term, economical solar applications were found, the conditions that would enhance the opportunities for solar IPH applications are identified.

    2014-01-01

    The Lower Saxony Research Network "Design of Environments for Ageing" (GAL) studied possible applications of assistive technology for enabling older adults to live longer and independent in their own home. As part of this work, a technical platform was developed as a common technical basis for all assistive systems in the project. This article presents an overview of the architecture and core functionality of the technical platform, which in the first generation was developed for use in a laboratory setting, and in a second generation was extended for use in the project's field studies, i.e. prototype installations in end-users homes. The field studies' primary objective was the evaluation of the assistive technologies, that were developed within the overall project. However, these studies also confirmed that the fundamental concept of the technical platform is valid, and the prototypes continuously worked 24 h a day for several months. However, there were some problems related to lack of infrastructure in the older adults' homes and human factors such as inadvertent placement of objects across sensors' field of view, acceptance problems due to aesthetical reasons or simply communication problems, which show that making complex technologies work for users with little technical experience is well possible, but requires a careful consideration of the complete service chain and related "soft factors".

    2016-07-01

    Nonshaved neurosurgery, cranial or spinal, is well reported among Caucasians but hardly among native Africans. The ungroomed scalp hairs of black Africans have unique anthropological characteristics needing special attention for shaveless cranial surgery. A technical report of the execution of this surgical procedure among an indigenous patient population in a sub-Sahara African country is presented, as well as an outcome analysis in a prospective cohort over a 7-year period. A total of 303 patients (211 males, 70 %) fulfilled the criteria for this study. The surgical procedure was primary in 278 (92 %) and redo in 8 %. It was emergency surgery in 153 (51 %). They were trauma craniotomies or decompressive craniectomies in 95 cases (31 %), craniotomies for tumour resections in 86 (28 %), and the surgical dissections for other conditions in 122 (41 %). The duration of surgery ranged from 30 min to 8.5 h, mean 2.5 (SD, 1.6), median 2. In-hospital clinical outcome was good (normal status or moderate deficit on dichotomized Glasgow outcome scale (GOS)) in 273 (90.1 %) cases while surgical site infections occurred in only 10 cases (3.3 %). The type of surgery, redo or primary, did not have any significant association with the in-hospital outcome (p = 0.5), nor with the presence of surgical site infection (SSI) (p = 0.7). The length of follow-up ranged from 2 to 63 months (mean, 7) with no untoward complications reported so far. Medium-term outcome of nonshaved neurosurgery in this indigenous black Africans remains favourable with no attendant significant adverse after-effects.

    Ventral rectopexy to the promontory has become one of the most strongly advocated surgical treatments for patients with full-thickness rectal prolapse and deep enterocele. Despite its challenges, laparoscopic ventral rectopexy with or without robotic assistance for selected patients can be performed with relatively minimal patient trauma thus creating the potential for same-day discharge. The aim of this prospective case-controlled study was to assess the feasibility, safety, and cost of day case robotic ventral rectopexy compared with routine day case laparoscopic ventral rectopexy. Between February 28, 2014 and March 3, 2015, 20 consecutive patients underwent day case laparoscopic ventral rectopexy for total rectal prolapse or deep enterocele at Michallon University Hospital, Grenoble. Patients were selected for day case surgery on the basis of motivation, favorable social circumstances, and general fitness. One out of every two patients underwent the robotic procedure (n = 10). Demographics, technical results, and costs were compared between both groups. Patients from both groups were comparable in terms of demographics and technical results. Patients operated on with the robot had significantly less pain (p = 0.045). Robotic rectopexy was associated with longer median operative time (94 vs 52.5 min, p case robotic ventral rectopexy is feasible and safe, but results in longer operative time and higher costs than classical laparoscopic ventral rectopexy for full-thickness rectal prolapse and enterocele.

    Perineural cysts of the sacrum, or Tarlov cysts, are cerebrospinal fluid (CSF)-filled sacs that commonly occur at the intersection of the dorsal root ganglion and posterior nerve root in the lumbosacral spine. Although often asymptomatic, these cysts have the potential to produce significant symptoms, including pain, weakness, and/or bowel or bladder incontinence. We present a case in which the sacral roof is removed and reconstructed via plated laminoplasty and describe how this technique could be of potential use in maximizing outcomes. We describe technical aspects of a sacral laminoplasty in conjunction with cyst fenestration for a symptomatic sacral perineural cyst in a 50-year-old female with severe sacral pain, lumbosacral radiculopathy, and progressive incontinence. This patient had magnetic resonance imaging (MRI) and computed tomography (CT)-myelographic evidence of a non-filling, 1.7 × 1.4 cm perineural cyst that was causing significant compression of the cauda equina and sacral nerve roots. This surgical technique was also employed in a total of 18 patients for symptomatic tarlov cysts with their radiographic and clinical results followed in a prospective fashion. Intraoperative images, drawings, and video are presented to demonstrate both the technical aspects of this technique and the regional anatomy. Postoperative MRI scan demonstrated complete removal of the Tarlov cyst. The patient's symptoms improved dramatically and she regained normal bladder function. There was no evidence of radiographic recurrence at 12 months. At an average 16 month followup interval 10/18 patients had significant relief with mild or no residual complaints, 3/18 reported relief but had persistent coccydynia around the surgical area, 2/18 had primary relief but developed new low back pain and/or lumbar radiculopathy, 2/18 remained at their preoperative level of symptoms, and 1/18 had relief of their preoperative leg pain but developed new pain and neurological deficits

    Full Text Available The main objective of this paper is to suggest a model for improving and retaining the highly qualified teachers in higher technical education. There are numerous researches going on all over the world regarding the key quality factors which are directly linked with teacher’s performance and the methods to improve them. Whatever the methods and measures, the teacher’s active participation and dedication is very important to achieve these objectives. A detailed questionnaire was distributed to highly qualified and experienced teachers who are working in engineering colleges for more than five years. Since the variables in this study are quality factors, the collected data is analyzed using the fuzzy logic and inference is drawn for getting more accurate results compared to probability study of the same case. Based on the results obtained from fuzzy inference system, a new model called Adaptive Performance-Incentive-Development (PID control system for improving the quality as well as retaining the highly qualified teachers in the teaching profession is created.

    The nine-month Phase 1 feasibility study was directed toward the application of supercritical water gasification (SCWG) for the economical production and end use of hydrogen from renewable energy sources such as sewage sludge, pulp waste, agricultural wastes, and ultimately the combustible portion of municipal solid waste. Unique in comparison to other gasifier systems, the properties of supercritical water (SCW) are ideal for processing biowastes with high moisture content or contain toxic or hazardous contaminants. During Phase I, an end-to-end SCWG system was evaluated. A range of process options was initially considered for each of the key subsystems. This was followed by tests of sewage sludge feed preparation, pumping and gasification in the SCW pilot plant facility. Based on the initial process review and successful pilot-scale testing, engineering evaluations were performed that defined a baseline system for the production, storage and end use of hydrogen. The results compare favorably with alternative biomass gasifiers currently being developed. The results were then discussed with regional wastewater treatment facility operators to gain their perspective on the proposed commercial SCWG systems and to help define the potential market. Finally, the technical and business plans were developed based on perceived market needs and the projected capital and operating costs of SCWG units. The result is a three-year plan for further development, culminating in a follow-on demonstration test of a 5 MT/day system at a local wastewater treatment plant.

  17. Marin Solar Village: feasibility study and technical analysis. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-08-31

    The energy needs of Hamilton Air Force Base's Solar Village for electricity and heating and cooling of buildings are considered and alternative ways of meeting the Village's requirements for these forms of energy are evaluated. First, Solar Village's energy demand is calculated and compared to a base case representing calculations for typical energy usage for a development of similar size and density that is in conformance with current state and local ordinances. The potential of selected alternative technologies to meet the Solar Village projected demand for electrical power and natural gas is evaluated. Scenarios were developed to reduce demand, particularly in the building sector. Four alternative on-site energy technologies have been evaluated: wind, solar thermal electric, biomass conversion, photovoltaics. Each alternative is analyzed in detail. Of the four alternatives considered, the one with the greatest present potential is biomass conversion. Two technologies have been incorporated into the design. A 3-acre land fill is covered with a mantle of soil. A network of pipes carries off the methane gas which is a natural product of anaerobic decomposition of the materials in the land fill. The second technology involves the planting of rapidly-growing trees on denuded and unused portions of the site; 50 acres devoted to tree production could yield 12% of the back-up energy required for home heating on a sustainable basis.

  18. PV Reconfiguration Systems: a Technical and Economic Study

    2017-03-01

    Full Text Available Dynamical electrical array reconfiguration strategies for grid-connected PV systems have been proposed as solution to improve energy production due to the mismatch effect of PV plants during partial shading conditions. Strategies are based on the use of dynamic connections between PV panels given by the employment of switches that allow for each panel the series, parallel or exclusion connections, physically changing the electrical connections between the related PV modules, consequentially modifying the layout of the plant. Usually the cost of the dynamic matrix is not taken into account. This novel work evaluates the economic advantages obtained by the use of reconfiguration strategies in PV systems, by taking into consideration the price of energy due to incentives in different European and non-European countries and correlates it with the employment of two types of reconfigurators, with different internal structures. For each of the incentives proposed by the different Countries, the main strength and weakness points of the possible investment are highlighted and critically analyzed. From this analysis, it can be stated that the adoption of reconfiguration systems, in certain cases, can be a very convenient solution.

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    This article examines the processes of technical mediation within familial care networks based on a study of home telecare targeted at older people. Supported by contributions from the actor—network theory as part of the social psychology of science and technology, these processes of technical mediation are analyzed using a qualitative approach. The data were gathered through six focus groups and four in-depth interviews; the participants in the study included users, relatives and formal carers. Thematic analysis techniques encompassing the information were used, revealing the effects on the patterns of caring relationships. The results show the interplay between presence-absence made possible by the devices; the two-way direction of care between the older people and the artifacts; and the process of sustaining care using the technology. We conclude that care should be seen as a socio-technical network where technology plays an active role in sustaining family relationships. PMID:23880730

    2012-11-01

    The efficacy of Compact International Experience (CIE) courses is assessed in this study. These courses were developed with the aim to raise student international awareness while retaining substantial engineering technical content. The courses were motivated by a strong student desire for engineering international studies as well as a drive by the home institution for internationalization of the curriculum. The experiences gained from delivering two distinct three-semester-unit engineering elective courses in three-week time frames in France and Australia are discussed. While the two courses, Topics in Fluid Mechanics and Advanced Electronic Circuit Design, focused on their technical content, the desire for student understanding of the cultural environment and the impact of engineering solutions from a global and societal viewpoint were strong driving factors for each. Assessment validates the hypothesis that CIE courses can successfully deliver substantial engineering technical content while providing an enriching international experience to students.

    In March 2011, the U.S. Department of Energy (DOE) awarded White Pine County, Nevada, a grant to assess the feasibility of renewable resource-related economic development activities in the area. The grant project included a public outreach and training component and was to include a demonstration project; however, the demonstration project was not completed due to lack of identification of an entity willing to locate a project in White Pine County. White Pine County completed the assessment of renewable resources and a feasibility study on the potential for a renewable energy-focused economic sector within the County. The feasibility study concluded "all resources studied were present and in sufficient quantity and quality to warrant consideration for development" and there were varying degrees of potential economic impact based on the resource type and project size. The feasibility study and its components were to be used as tools to attract potential developers and other business ventures to the local market. White Pine County also marketed the County’s resources to the renewable energy business community in an effort to develop contracts for demonstration projects. The County also worked to develop partnerships with local educational institutions, including the White Pine County School District, conducted outreach and training for the local community.

  10. Factors That Influence Technical Efficiency of Sorghum Production: A Case of Small Holder Sorghum Producers in Lower Eastern Kenya

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Majority of the rural households in Kenya depend on agriculture as a source of food and livelihood. Agricultural productivity has been declining due to many factors resulting in increased food insecurity in the country. Consequently, there is a renewed interest in promoting drought-tolerant crops such as sorghum which thrives in the arid and semiarid lands of the developing world. However, performance of sorghum production among the smallholder farmers has still remained low. This study was thus carried out to identify factors that influence technical efficiency of sorghum production among smallholder farmers in Machakos and Makindu districts of the lower eastern Kenya. Collected data on farm and farmer characteristics were analysed by use of descriptive statistics and Tobit model. Result highlights show that technical efficiency was influenced positively by formal education level of the household, experience in sorghum farming, membership in farmers associations, use of hired labour, production advice, and use of manure. Surprisingly household size, meant to enhance labour, had a negative influence. To increase technical efficiency, efforts should focus on improving information flows on agronomic practices. Farmers should also be encouraged to form and actively participate in various farmers associations, which enhance learning and pooling of labour resources, hence improving technical efficiency.

    A neutrino detector is proposed to be developed for use on a space probe in close orbit of the Sun. The detector will also be protected from radiation by a tungsten shield Sun shade, active veto array and passive cosmic shielding. With the intensity of solar neutrinos substantially greater in a close solar orbit than on the Earth only a small 250 kg detector is needed. It is expected that this detector and space probe studying the core of the Sun, its nuclear furnace and particle physics basic properties will bring new knowledge beyond what is currently possible for Earth bound solar neutrino detectors.

    2012-12-01

    Full Text Available Abstract Background The introduction of a new method of transmitting prescriptions from general practices to community pharmacies in England (Electronic Prescription Service Release 2 (EPS2 has generated debate on how it will change work practice. As EPS2 will be a key technical element in dispensing, we reviewed the literature to find that there were no studies on how social and technical elements come together to form work practice in community pharmacies. This means the debate has little point of reference. Our aim therefore was to study the ways social and technical elements of a community pharmacy are used to achieve dispensing through the development of a conceptual model on pharmacy work practice, and to consider how a core technical element such the EPS2 could change work practice. Method We used ethnographic methods inclusive of case-study observations and interviews to collect qualitative data from 15 community pharmacies that were in the process of adopting or were soon to adopt EPS2. We analysed the case studies thematically and used rigorous multi-dimensional and multi-disciplinary interpretive validation techniques to cross analyse findings. Results In practice, dispensing procedures were not designed to take into account variations in human and technical integration, and assumed that repetitive and collective use of socio-technical elements were at a constant. Variables such as availability of social and technical resources, and technical know-how of staff were not taken into account in formalised procedures. Yet community pharmacies were found to adapt their dispensing in relation to the balance of social and technical elements available, and how much of the social and technical elements they were willing to integrate into dispensing. While some integrated as few technical elements as possible, some depended entirely on technical artefacts. This pattern also applied to the social elements of dispensing. Through the conceptual

    Full Text Available The Château de Germolles is one of the rare palace in France dating from the 14th century. The noble floor is decorated with wall paintings that are a unique example of courtly love spirit that infused the princely courts of the time. After being concealed sometime in the 19th century, the paintings were rediscovered and uncovered in the middle of the 20th century and partly restored at the end of the 1990s. No scientific documentation accompanied these interventions and important questions, such as the level of authenticity of the mural decorations and the original painting technique(s used in the medieval times remained unanswered. The combined scientific and financial supports of COSCH Cost Action and DRAC-Burgundy enabled to study Germolles’ wall paintings using some of the most innovative imaging and analytical techniques and to address some of the questions raised. The study provided significant information on the material used in the medieval times and on the conservation condition of the paintings. The data collected is vast and varied and exposed the owners of the property to the challenges of data management.

    2013-01-01

    Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

    In this new and current era of technology, advancements and techniques, efficient and effective text document classification is becoming a challenging and highly required area to capably categorize text documents into mutually exclusive categories. Fuzzy similarity provides a way to find the similarity of features among various documents. In this paper, a technical review on various fuzzy similarity based models is given. These models are discussed and compared to frame out their use and necessity. A tour of different methodologies is provided which is based upon fuzzy similarity related concerns. It shows that how text and web documents are categorized efficiently into different categories. Various experimental results of these models are also discussed. The technical comparisons among each model's parameters are shown in the form of a 3-D chart. Such study and technical review provide a strong base of research work done on fuzzy similarity based text document categorization.

    BackgroundA novel coaxial biopsy system powered by a handheld drill has recently been introduced for percutaneous bone biopsy. This technical note describes our initial experience performing fluoroscopy-guided vertebral body biopsies with this system, compares the yield of drill-assisted biopsy specimens with those obtained using a manual technique, and assesses the histologic adequacy of specimens obtained with drill assistance.MethodsMedical records of all single-level, fluoroscopy-guided vertebral body biopsies were reviewed. Procedural complications were documented according to the Society of Interventional Radiology classification. The total length of bone core obtained from drill-assisted biopsies was compared with that of matched manual biopsies. Pathology reports were reviewed to determine the histologic adequacy of specimens obtained with drill assistance.ResultsTwenty eight drill-assisted percutaneous vertebral body biopsies met study inclusion criteria. No acute complications were reported. Of the 86 % (24/28) of patients with clinical follow-up, no delayed complications were reported (median follow-up, 28 weeks; range 5–115 weeks). The median total length of bone core obtained from drill-assisted biopsies was 28 mm (range 8–120 mm). This was longer than that obtained from manual biopsies (median, 20 mm; range 5–45 mm; P = 0.03). Crush artifact was present in 11 % (3/28) of drill-assisted biopsy specimens, which in one case (3.6 %; 1/28) precluded definitive diagnosis.ConclusionsA drill-assisted, coaxial biopsy system can be used to safely obtain vertebral body core specimens under fluoroscopic guidance. The higher bone core yield obtained with drill assistance may be offset by the presence of crush artifact.

    Wu-Rorrer, Billy Ray

    The purpose of this qualitative method study with a Delphi research design sought to determine how STEM programs can be effectively integrated into middle school career and technical education programs by local, state, and national educators, administrators, directors, specialists, and curriculum writers. The significance of the study is to provide leaders in CTE with a greater awareness, insight, and strategies about how CTE programs can more effectively integrate academics into career and technical education programs through STEM-related programming. The findings will increase the limited amount of available literature providing best practice strategies for the integration of STEM curriculum into middle school CTE programs. One basic question has guided this research: How can STEM programs be effectively integrated into middle school career and technical education programs? A total of twelve strategies were identified. The strategies of real-world applications and administrative buy-in were the two predominant strategies consistently addressed throughout the review of literature and all three sub-questions in the research study. The Delphi design study consisted of pilot round and three rounds of data collection on barriers, strategies, and professional development for STEM integration in middle school career and technical education programs. Four panelists participated in the pilot round, and 16 panel members not involved in the pilot round participated in the three rounds of questioning and consensus building. In the future, more comprehensive studies can build upon this foundational investigation of middle school CTE programs.

    This document gives an overview of the scientific results obtained under the DOE grant, and references the journal articles which give more complete descriptions of the various topics. Recently, the research has been focused on 2-dimensional vortices and turbulence: experiments using a new camera-diagnosed electron plasma apparatus have given surprising results which both clarify and challenge theories. Here, the crossfield E x B flow of the electron plasma is directly analogous to the 2-d flow of an ideal fluid such as water, and may also give insight into more complicated poloidal flows exhibited in toroidal plasmas. The shear-flow instabilities, turbulence, and vortices can be accurately observed, and the free relaxation of this turbulence has been characterized. The physical processes underlying the complicated turbulent evolution can also be studied in more controlled near-linear regimes. The original experimental focus of this program was on radial particle transport from applied external field asymmetries. Here, this research program clearly identified the importance of the collective response of the plasma, giving smaller fields from shielding, or enhanced fields from resonant modes. Experiments and theory work have also elucidated the flow of a plasma along the magnetic field. Finally, some theory was pursued for direct application to fusion plasmas, and to gravitating gas clouds in astrophysics. This program was highly successful in clarifying basic plasma transport processes.

    This study identifies potential applications and design requirements for ceramic materials (CMs) and ceramic composite materials (CCMs) in the NGNP hightemperature gas-cooled reactor (HTGR) primary circuit. Components anticipated for fabrication from non-graphite CMs and CCMs are identified along with recommended normal and off-normal operating conditions. The evaluation defines required dimensions and material properties of the candidate materials for normal operating conditions (NOC), anticipated transients, abnormal events, and design basis events. The report also identifies additional activities required for codifying the selected materials. The activities include ASTM Standard and ASME Code development and other work to support NRC licensing of the plant. Evaluation of the NGNP baseline design indicates components requiring either CMs or CCMs depend upon the reactor operating temperatures. For a reactor outlet temperature of 900 oC, four of the five evaluated components would benefit from either CMs or CCMs. Although some thermal and mechanical data exist for most of the candidate materials, they all need additional irradiation, thermal, and mechanical testing. The codification process must take into account the type of material and the geometry of components using either CMs or CCMs. The process requires close integration of the design and the research and development (R&D) program, which has already started by using preliminary control rod component designs as the basis for establishing specimen geometry and test conditions. The remaining time and budget for completing the R&D program need further assessment.

    established, based on the review of the geological and hydrogeological characteristics of the deformation zone NE-1. In the descriptive model, the water-bearing fracture zone consists of an 8 metre wide central core zone and a 15 meter wide transition zone sited on either side of the core zone. Rock mechanical and hydrogeological properties of the rock mass as well as in situ rock stresses are assigned in the descriptive model. To highlight the important technical issues in tunnelling through water-bearing fracture zones, system analysis and problem identification based on a literature review of relevant case histories are conducted. The identified important technical issues, namely large water inflow and tunnel stability, will be the objects to be analysed in this study. Control of water inflows is the key issue for the safe passage of a tunnel through a water-bearing fracture zone with the characteristics of NE-1. Technical issues associated with the two most used methods for water inflow control, namely grouting and ground freezing are discussed. The analyses regarding water inflows associated with grouting are presented. The degree of difficulty for water inflow control increases with depth. The study indicates that control of water inflows at all the depths could be achieved by grouting with current technology. But ground freezing might be an alternative for the core zone, for instance at a depth of 600 metres. Due to the high water pressure that may be encountered at a depth of 600 metres, precautions must be taken in the decision making process in selecting the most appropriate methods of groundwater control. The deformation analysis indicates that large deformations are unlikely to occur in the transition zone, even at a depth of 600 metres. The reduction in rock mass quality in the core zone, however, is likely to result in large deformations at great depths. The estimated mean values of deformation for an unsupported tunnel in the core zone are 60 mm and 130 mm at

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    Full Text Available The research on a Technological University of Brazil, among students in Engineering, revealed that women occupy no more than 12 % (in general of the places at the Institution. The university study that the girls most prefer is the Engineering of Buildings and the other one, where there are the least number of women, is Mechanics Engineering. The qualitative research with the students, made by interviews, showed that there is a gender discrimination among them. The boys do not consider their schoolmates competents for the exact sciences. The girls have to do a greater effort than the boys to success and to be respected by them. But even so they recognize that will not have the same opportunities of work that the men will. However, gender changes among the students are evidences that women have reached important places at the technological field.La investigación en una Universidad Tecnológica de Brasil entre estudiantes de los cursos de ingeniería ha mostrado que las mujeres no ocupan más que 12 % (en general de las plazas de la Institución. El curso con más estudiantes es el de Ingeniería Civil, mientras el curso con el más pequeño número de mujeres es el de Mecánica. La metodología de la investigación ha sido cualitativa. Las entrevistas con chicas-chicos de los cursos investigados revelaron que hay discriminación entre los estudiantes que no consideran a sus compañeras de curso competentes para los estudios de ciencias exactas. Para que sean respetadas ellas tienen que estudiar mucho más que ellos, pero, aunque logren muy buenas evaluaciones, reconocen que en el mercado laboral tendrán menos oportunidades de trabajo que sus colegas. Entretanto, los cambios de género entre los y las estudiantes evidencian que las mujeres están conquistando espacios importantes.

    The 1993 Pacific Northwest Loads and Resources Study establishes the Bonneville Power Administration`s (BPA) planning basis for supplying electricity to BPA customers. The Loads and Resources Study is presented in three documents: (1) this technical appendix detailing loads and resources for each major Pacific and Northwest generating utility, (2) a summary of Federal system and Pacific Northwest region loads and resources, and (3) a technical appendix detailing forecasted Pacific Northwest economic trends and loads. This analysis updates the 1992 Pacific Northwest Loads and Resources Study Technical Appendix published in December 1992. This technical appendix provides utility-specific information that BPA uses in its long-range planning. It incorporates the following for each utility (1) Electrical demand firm loads; (2) Generating resources; and (3) Contracts both inside and outside the region. This document should be used in combination with the 1993 Pacific Northwest Loads and Resources Study, published in December 1993, because much of the information in that document is not duplicated here.

    Obsessional slowness is a rare psychiatric disorder with few treatment options and limited research to date. Some suggest that targeted behavioural interventions may reduce the time taken for functional daily activities. To examine whether a behavioural intervention would reduce the amount of time taken for an adolescent with obsessional slowness to walk to class. A single-subject A-B-A withdrawal design was incorporated into this case study. The treatment involved one-to-one pacing and prompting during the subject's walk to gym class. Walking times to gym class were measured during a baseline phase, during a one-month treatment phase, and during a post-treatment follow-up phase. The subject's walking times decreased during the treatment phase. Post-treatment walking times suggested a carry-over effect. This study adds to the sparse evidence on treatments for obsessional slowness and suggests occupation-based treatment options.

    Full Text Available This work aims to propose a model for the conduct of cultural change in the IT department of a company in the telecommunications industry. To achieve the goal proposed exploratory, technical procedures used were the case study and literature review. The techniques of data collection in the case study were: participant observation, unstructured interview and document analysis. The proposed model consists of five steps: analysis of the company's strategic planning, cultural diagnosis of the IT department, brainstorming with the staff and managers, compared to the case studies surveyed and proposed actions for the conduct of cultural change. We conclude that a receptive environment, employees not only understand why the changes are necessary, but engage with the process and faithfully executes the steps required, favoring the strategic positioning of the company.

    2013-12-01

    Full Text Available Introduction. Esophageal atresia encompasses a group of congenital anomalies comprising of an interruption of the esophageal continuity with or without a persistent communication with the trachea. Esophageal atresia with tracheoesophageal fistula (type C accounts for 85% of all esophageal atresia. Minimally invasive approach to correct esophageal atresia with distal fistula is becoming more generally accepted. The outcome of these technique are critically analyzed and compared with results from open repair. We present one case of type IIIB esophageal atresia treated by a thoracoscopic approach. Case Report. The patient was a 2-days-old infant male, weight 3 kg with esophageal atresia and distal tracheoesophageal fistula without other associated disease. A polidramanios was detected in prenatal age by a prenatal ultrasound evaluation. He underwent to a thoracoscopic repair of the defect. The operation was approached through the right chest using a three-trocar technique (three 5-mm with the patient placed in a three-quarter prone position. The azygos vein was ligated by Ligature device. The fistula was ligated by two resorbable stiches suture and dissected, the proximal esophagus was opened and an anastomosis was made over a 6 Ch nasogastric tube with interrupted and resorbable stiches suture. On the postoperative day 7, gastrografin swallow was performed and oral feeding was started. The patient’s six month upper Gastrointestinal barium studies was normal. Discussion and conclusion. Thoracoscopic repair of esophageal atresia is considered to be one of the more advanced and most difficult pediatric surgical procedures and it undoubtely has necessary an elevated learning curve. The minimally invasive approach was larged accepted in the last ten years also for the well documented sequelae of traditional open repair of esophageal atresia. More experience is needed to determine the exact place of this approach.

    The transoral robotic approach to parapharyngeal space (PPS) tumors is a new technique with limited data available on its feasibility, safety, and efficacy. We analyzed our experience with transoral robotic excisions of PPS tumors to evaluate the safety and efficacy of this technique. Retrospective chart analysis at tertiary academic medical center. From July 2010 to June 2014, 17 patients who had transoral robotic excision of PPS tumors were included in the study. Our cohort had an average age of 61.6 years and was 52.9% male. All patients had successful removal of their PPS tumors, and the average size of the tumors was 27.3 cm(3) (range 2-80 cm(3) ). Two cases (11.7%) required a cervical incision to assist with tumor removal. The average total operative time was 140.5 minutes. Two PPS PAs had focal areas of capsule rupture and one was fragmented. The average length of stay was 1.8 days (range 1-7 days), and all patients were discharged on an oral diet. Three patients experienced complications. There was no clinical or radiographic evidence of recurrence. This is the largest single-institution case series of transoral robotic approaches to PPS tumors. We demonstrate that this approach is feasible and safe but also note limitations of the robotic approaches for tumors on the far lateral and superior areas of the PPS, which required transcervical assistance. There were no patients who demonstrated recurrent tumor either radiographically or clinically. 4.

    The endoscopic technique has been described as a minimally invasive method for spontaneous hematoma evacuation, as a safe and effective treatment. Nevertheless, to our knowledge, there is no description of a technical report of traumatic intracerebral hematoma removal using the neuroendoscope. A 47-year-old man was admitted sustaining 13 points in Glasgow coma scale with brain computed tomography (CT) scan showing a temporal contusion. Guided by a 3D reconstructed CT, using the program OsiriX®, the posterior limit of the hematoma was identified. A burr hole was placed at the posterior temporal region, and we used the neuroendoscope to assist the hematoma evacuation. The postoperative tomography showed adequate hematoma removal. He was discharged from hospital 48 h after surgery. Two weeks later, he was conscious and oriented temporally. This endoscopic-assisted technique can provide safe removal of traumatic hematomas of the temporal lobe.

    Highlights: • This paper is to secure knowledge and expand domestic specialists for license and regulation of future fusion facilities including K-DEMO. - Abstract: Currently, Korea Domestic Agency (KODA) for the International Thermonuclear Experimental Reactor (ITER) project or the ITER Korea has been conducting follow-up surveys and development researches for the core technologies of its non-procurement items. This eventually aims to secure implicit as well as explicit knowledge and expand domestic specialists for future fusion facilities including K-DEMO. As a part of the project, the comparative analysis and gap study of technical standards and Quality Assurance (QA) system between ITER and Korean nuclear facilities are being performed. The goal of this study is to present a roadmap re-systematizing current safety-related standards for the fission-based facilities into fusion-based facilities in Republic of Korea. The research is considering two different tracks. First one is to secure the state-of-the-art of the fusion technical standards continually updated. For its investigation, we organized the Korean fusion safety advisory group that consists of experts from institutes, industries, and universities. The latest information of technical standards have been gathered and updated from each area of expert in periodic manner. The information is classified into Product Breakdown Structure (PBS) including safety classification, major safety issues, analysis computer codes, etc. This task will be re-organized this year such that the technical standards for procurement as well as non-procurement items can be accumulated in systematic and sustainable manner. Second one, called “Gap Study,” is to compare the requirements for domestic nuclear facilities and the results from the first track on the basis of experts’ opinion from the national and private sectors and to recommend the approaches to overcome technical and administrative barriers. The result is

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    Healthcare increasingly recognises and focusses on the phenomena of 'safe practice' and 'patient safety.' Success with non-technical skills (NTS) training in other industries has led to widespread transposition to healthcare education, with communication and teamwork skills central to NTS frameworks. This study set out to identify how the context of interprofessional simulation learning influences NTS acquisition and development of 'safety' amongst learners. Participants receiving a non-technical skills (NTS) safety focussed training package were invited to take part in a focus group interview which set out to explore communication, teamwork, and the phenomenon of safety in the context of the learning experiences they had within the training programme. The analysis was aligned with a constructivist paradigm and took an interactive methodological approach. The analysis proceeded through three stages, consisting of open, axial, and selective coding, with constant comparisons taking place throughout each phase. Each stage provided categories that could be used to explore the themes of the data. Additionally, to ensure thematic saturation, transcripts of observed simulated learning encounters were then analysed. Six themes were established at the axial coding level, i.e., analytical skills, personal behaviours, communication, teamwork, context, and pedagogy. Underlying these themes, two principal concepts emerged, namely: intergroup contact anxiety - as both a result of and determinant of communication - and teamwork, both of which must be considered in relation to context. These concepts have subsequently been used to propose a framework for NTS learning. This study highlights the role of intergroup contact anxiety and teamwork as factors in NTS behaviour and its dissipation through interprofessional simulation learning. Therefore, this should be a key consideration in NTS education. Future research is needed to consider the role of the affective non-technical

    established, based on the review of the geological and hydrogeological characteristics of the deformation zone NE-1. In the descriptive model, the water-bearing fracture zone consists of an 8 metre wide central core zone and a 15 meter wide transition zone sited on either side of the core zone. Rock mechanical and hydrogeological properties of the rock mass as well as in situ rock stresses are assigned in the descriptive model. To highlight the important technical issues in tunnelling through water-bearing fracture zones, system analysis and problem identification based on a literature review of relevant case histories are conducted. The identified important technical issues, namely large water inflow and tunnel stability, will be the objects to be analysed in this study. Control of water inflows is the key issue for the safe passage of a tunnel through a water-bearing fracture zone with the characteristics of NE-1. Technical issues associated with the two most used methods for water inflow control, namely grouting and ground freezing are discussed. The analyses regarding water inflows associated with grouting are presented. The degree of difficulty for water inflow control increases with depth. The study indicates that control of water inflows at all the depths could be achieved by grouting with current technology. But ground freezing might be an alternative for the core zone, for instance at a depth of 600 metres. Due to the high water pressure that may be encountered at a depth of 600 metres, precautions must be taken in the decision making process in selecting the most appropriate methods of groundwater control. The deformation analysis indicates that large deformations are unlikely to occur in the transition zone, even at a depth of 600 metres. The reduction in rock mass quality in the core zone, however, is likely to result in large deformations at great depths. The estimated mean values of deformation for an unsupported tunnel in the core zone are 60 mm and 130 mm at

    Night Ventilation is a critical technique of passive cooling, as it combines a significant decrease of cooling demand and improvement of thermal comfort and indoor air quality. The aim of the present paper is to study the technical and legal aspects of night ventilation in urban climatic conditions. The technical part examines the efficiency of night ventilation techniques for urban residential buildings. Moreover, the influence of urban heat island on the night ventilation effectiveness is studied. Urban heat provokes the degradation of urban air quality and causes changes in the urban area microclimate which reduce the night ventilation effectiveness as a passive cooling technique. Moreover, this paper studies the legal framework of energy efficiency in buildings and pinpoints the institutional deficiencies of the existing regulation regarding energy efficiency and passive cooling techniques

    Multidrug-resistant tuberculosis (MDR-TB), the prevalence of which has increased across the globe in recent years, is a serious threat to public health. Timely diagnosis of MDR-TB, especially among new TB cases, is essential to facilitate appropriate treatment, which can prevent further emergence of drug resistance and its spread in the population. The present case report from India aims to address some operational challenges in diagnosing MDR-TB among new cases and potential measures to overcome them. It argues that even after seven years of implementing the DOTS-Plus program for controlling MDR-TB, India still lacks the technical capacity for rapid MDR-TB diagnosis. The case report underscores an urgent need to explore the use of WHO-endorsed techniques such as Xpert MTB/Rif and commercial assays such as Genotype MTBDR for rapid diagnosis of MDR-TB among new cases. Suitable applications may be found for other TB high-burden countries where MDR-TB is a major concern.

    Today disasters are a part of many people's lives. Iran has a long history of disaster events and nurses are one of the most significant groups within the Iranian disaster relief operations, providing immediate and long-term care for those affected by the disaster. However, the technical competence of Iranian nurses and their training for this work has received little attention. This article presents the results of a study that aims to explore this context. A qualitative study was conducted using in-depth interviews to collect data from 30 nurses, who were deliberately selected from the health centers affiliated to the Isfahan University of Medical Sciences. Themes were identified using the conventional qualitative content analysis. The trustworthiness of the study was supported by considering the auditability, neutrality, consistency, and transferability. The study lasted from 2011 to 2012. Data analysis undertaken for the qualitative study resulted in the identification of five main themes, which included: (1) Management competences, (2) ethical and legal competences, (3) team working, and (4) personal abilities and the specific technical competences presented in this report. This report presents an overview of the nursing technical capabilities required for Iranian nurses during disaster relief. It is argued that additional competencies are required for nurses who care in high-risk situations, including disasters. Nurses need to prepare themselves more effectively to be responsible and effective in nursing care.

    2014-12-01

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    Marcelo Moriconi Bezerra

    2012-01-01

    Full Text Available This article analyzes the political imaginaries in the official discourses about the public administration reforms in Argentina, Chile and Uruguay, during the nineties. The new management methods are based on technical concepts that do not signify by themselves. To acquire effective meaning, these concepts depend on systems of ideas about the significance of the State and democracy, settled in each particularcase. Concepts derived from the discourse analysis school, such as hegemony, nodal points or sedimentation, are useful to understand the strategies to construct the symbolic reality in each case. This reality will depend on the political imaginary which determines ‘what is possible to do’ and ‘what is tolerable’ in each particular society. The election of limited realities, focused only on formal nstitutions, has been constant in the analyzed discourses, which explains why the reforms were inefficient to remove common cultural practices such as clientelism.

    Full Text Available Abstract Background The Government of Ghana has been implementing various health sector reforms (e.g. user fees in public health facilities, decentralization, sector-wide approaches to donor coordination in a bid to improve efficiency in health care. However, to date, except for the pilot study reported in this paper, no attempt has been made to make an estimate of the efficiency of hospitals and/or health centres in Ghana. The objectives of this study, based on data collected in 2000, were: (i to estimate the relative technical efficiency (TE and scale efficiency (SE of a sample of public hospitals and health centres in Ghana; and (ii to demonstrate policy implications for health sector policy-makers. Methods The Data Envelopment Analysis (DEA approach was used to estimate the efficiency of 17 district hospitals and 17 health centres. This was an exploratory study. Results Eight (47% hospitals were technically inefficient, with an average TE score of 61% and a standard deviation (STD of 12%. Ten (59% hospitals were scale inefficient, manifesting an average SE of 81% (STD = 25%. Out of the 17 health centres, 3 (18% were technically inefficient, with a mean TE score of 49% (STD = 27%. Eight health centres (47% were scale inefficient, with an average SE score of 84% (STD = 16%. Conclusion This pilot study demonstrated to policy-makers the versatility of DEA in measuring inefficiencies among individual facilities and inputs. There is a need for the Planning and Budgeting Unit of the Ghana Health Services to continually monitor the productivity growth, allocative efficiency and technical efficiency of all its health facilities (hospitals and health centres in the course of the implementation of health sector reforms.

    2016-10-01

    Subependymal giant cell astrocytoma (SEGA) is a rare tumor occurring almost exclusively in patients with tuberous sclerosis complex. Although open resection remains the standard therapy, complication rates remain high. To minimize morbidity, less invasive approaches, such as endoscope-assisted resection, radiosurgery, and chemotherapy with mTOR pathway inhibitors, are also used to treat these lesions. Laser interstitial thermal therapy (LITT) is a relatively new modality that is increasingly used to treat a variety of intracranial lesions. In this report, the authors describe two pediatric cases of SEGA that were treated with LITT. In both patients the lesion responded well to this treatment modality, with tumor shrinkage observed on follow-up MRI. These cases highlight the potential of LITT to serve as a viable minimally invasive therapeutic approach to the management of SEGAs in the pediatric population.

    The etiology and proper treatment of symptomatic subacute subdural hematomas remains to be elucidated. We describe two cases of this entity successfully treated with small craniotomy and evacuation. Both patients initially treated conservatively for traumatic thin subdural hematomas because of poor medical condition and mild neurological symptoms, but suffered abrupt neurological deterioration between 2 and 3 weeks after the admission. CT scan showed decreased density of hematomas with minimal increase in volume, and significant swelling of ipsilateral cerebral hemisphere. Urgent two-burr-hole small craniotomy was effective for evacuation of partially organized hematoma. During surgery, definite hematoma membrane was not confirmed. Postoperatively, brain swelling rapidly disappeared and both patients discharged ambulatory without neurological deficit. The present cases are a reminder of this peculiar type of hematoma in patients with delayed neurological deterioration after nonsurgical management of acute subdural hematoma. The rationale for use of small craniotomy is discussed in terms of current understanding of pathogenetic mechanism for this unusual condition.

    Among patients with respiratory insufficiency awaiting lung transplantation, small adult patients have a lower opportunity of receiving size-matched pulmonary grafts, because of the shortage of donors, particularly those of small size. Reducing the size of an oversized graft is one of the methods to increase the donor pool; similarly, ex vivo lung perfusion is an emerging technique aimed toward the same purpose. We describe how we combined the 2 techniques (lobar transplantation plus contralateral nonanatomic graft reduction during ex vivo lung perfusion) to overcome graft shortage in a clinical case. For the 1st time, this case report demonstrates that surgical manipulation during ex vivo lung perfusion does not affect the functional improvement in a lung previously judged to be not suitable for transplantation. The 6-month follow-up results are similar to those of standard bilateral lung transplantation.

    Full Text Available Liposarcoma is the most common soft tissue sarcoma in adults. These tumors have a high incidence of osseous metastases, with a propensity to the spine; however, primary spinal involvement is very rare. A 56-year-old female patient presented with a 4 month history of cervical pain, including radiation to both upper limbs, without radicular distribution. Magnetic resonance imaging (MRI showed an epidural lesion with gadolinium enhancement and bilateral extension into the intervertebral neural foramina (C5–C7, with spreading on the right side of the tumor into paravertebral tissue. The histopathological diagnosis was myxoid liposarcoma. To our knowledge it is the first case of primary myxoid liposarcoma of the cervical spine in the literature. Although rare, our case demonstrates that liposarcoma should be considered in the differential diagnosis of cervical tumors.

    1994-05-01

    The paper discusses two aspects of Sandia`s Wind Energy Program. The first section of the paper presents a case study of fatigue in wind turbines. This case study was prepared for the American Society of Testing Material`s (ASTM) Standard Technical Publication (STP) on fatigue education. Using the LIFE2 code, the student is lead through the process of cumulative damage summation for wind turbines and typical data are used to demonstrate the range of life estimates that will result from typical parameter variations. The second section summarizes the results from a workshop held by Sandia and the National Renewable Energy Laboratory (NREL) to discuss fatigue life prediction methodologies. This section summarizes the workshop discussions on the use of statistical modeling to deduce the shape and magnitude of the low-probability-of-occurrence, high-stress tail of the load distribution on a wind turbine during normal operation.

  17. Five misunderstandings about case study research

    DEFF Research Database (Denmark)

    Flyvbjerg, Bent

    2004-01-01

    This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most...... useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one...... and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more...

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    The purpose of this case report was to describe a novel method to retrieve a herniated lumbar interbody cage. Transforaminal lumbar interbody fusion (TLIF) is an increasingly popular method of spinal fixation and fusion. Unexpected retropulsion of an interbody is a rare event that can result in intractable pain or motor compromise necessitating surgical retrieval of the interbody. Both anterior and posterior approaches to removing migrated cages may be associated with significant surgical morbidity and mortality. A 60-year-old woman underwent an L4-S1 TLIF coupled with pedicle screw fixation at a previous hospital 5 years prior to admission. She noted sudden-onset bilateral lower extremity weakness and right-sided foot drop. Magnetic resonance imaging and radiographs were notable for purely centrally herniated interbody. A posterior, midline transdural approach was used to retrieve the interbody. Situated in between nerve rootlets to the ventral canal, this virgin corridor allowed us to easily visualize and protect neurological structures while safely retrieving the interbody. The patient experienced an immediate improvement in symptoms and was discharged on postoperative day 3. At 12-month follow-up, she had no evidence of cerebrospinal fluid (CSF) leak and had returned to normal activities of daily living. While the risk of CSF leak may be higher with a transdural approach, we maintain that avoiding unnecessary retraction of the nerve roots may outweigh this risk. To our knowledge, this is the first case report of a transdural approach for the retrieval of a retropulsed lumbar interbody cage.

    Full Text Available We report a case of pancreaticoduodenectomy for pancreatic head cancer with circumportal pancreas (CP. A 76-year-old woman was referred to our hospital with complaint of generalized pruritus. Dynamic computed tomography (CT revealed an unenhanced mass at the head of the pancreas and a dilated main pancreatic duct (MPD behind the superior mesenteric vein (SMV. She was diagnosed with pancreatic head cancer with CP and underwent subtotal stomach-preserving pancreaticoduodenectomy (SSpPD. The pancreas was transected both beneath and above the SMV, and the dominant dorsal edge of the pancreas was mobilized and anastomosed with the gut, whereas the ventral edge was closed by suture and attached to the gut. The postoperative course was uneventful without the occurrence of pancreatic fistula or bleeding. CP is a rare anomaly in which a portal vein (PV is encircled by the annular pancreatic parenchyma. CP is usually asymptomatic without any significant comorbidity but may become a surgical hazard when pancreaticoduodenectomy is performed. We report our successfully treated case, with special references to the technical approach for pancreatic anastomosis.

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

    Full Text Available Background: Intracranial germ cell tumors (GCTs represent less than 5% of pediatric brain tumors. Neurosurgical treatment remains essential in the management of patients with intracranial nongerminomatous GCT. Case Description: A 12-year-old girl presented with clinical features of neurohypophyseal dysfunction and rapidly progressive visual worsening. Magnetic resonance imaging (MRI showed a lesion arising from the sella with a significant suprasellar component, compressing the optic chiasm and extending into the third ventricle. The tumor was removed via an endoscopic endonasal transtuberculum-transplanum approach and the histology revealed a mixed germinoma. In the postoperative course, a conspicuous improvement of visual function was observed; an early postoperative MRI showed near-total removal of the lesion. The patient was referred to pediatric oncologist for the adjunctive chemotherapy and radiotherapy. Conclusions: The management of primary intracranial sellar and suprasellar germinomas still remains controversial. With this report we highlighted another possible surgical option among therapeutic strategies for these highly malignant tumors.

    Background: Several benefits have been described over the years of the transradial versus femoral endovascular approach to cardiac interventions. Consequently, its use has become habitual at most centers that perform cardiac catheterizations. This paper details a right transradial approach, incorporating a variety of coils or flow diverters, which can be utilized for the endovascular treatment of different cerebral aneurysms. Methods: From 2014 to 2016, we performed 40 endovascular procedures to treat cerebral aneurysms adopting the same right transradial approach. Five aneurysms were treated with flow diverters and 35 were treated with coils. Seven of these aneurisms were asymptomatic, whereas 33 had already ruptured. Results: Satisfactory treatment was achieved in all cases through the same approach in the absence of any complications. Conclusions: A right transradial approach may be satisfactory for the endovascular treatment of different cerebral aneurysms, including aneurysms in either hemisphere. This is the largest series of cerebral aneurysms treated through a transradial approach. PMID:28584676

    ABSTRACT Background: Healthcare increasingly recognises and focusses on the phenomena of ‘safe practice’ and ‘patient safety.’ Success with non-technical skills (NTS) training in other industries has led to widespread transposition to healthcare education, with communication and teamwork skills central to NTS frameworks. Objective: This study set out to identify how the context of interprofessional simulation learning influences NTS acquisition and development of ‘safety’ amongst learners. Methods: Participants receiving a non-technical skills (NTS) safety focussed training package were invited to take part in a focus group interview which set out to explore communication, teamwork, and the phenomenon of safety in the context of the learning experiences they had within the training programme. The analysis was aligned with a constructivist paradigm and took an interactive methodological approach. The analysis proceeded through three stages, consisting of open, axial, and selective coding, with constant comparisons taking place throughout each phase. Each stage provided categories that could be used to explore the themes of the data. Additionally, to ensure thematic saturation, transcripts of observed simulated learning encounters were then analysed. Results: Six themes were established at the axial coding level, i.e., analytical skills, personal behaviours, communication, teamwork, context, and pedagogy. Underlying these themes, two principal concepts emerged, namely: intergroup contact anxiety – as both a result of and determinant of communication – and teamwork, both of which must be considered in relation to context. These concepts have subsequently been used to propose a framework for NTS learning. Conclusions: This study highlights the role of intergroup contact anxiety and teamwork as factors in NTS behaviour and its dissipation through interprofessional simulation learning. Therefore, this should be a key consideration in NTS education. Future

    Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were found to be essential for the identification of signs appropriate for instruction. The results of this study also indicate a need for a systematic approach to examine both sign selection and its impact on learning by deaf students. Recommendations are made for the development of lexical databases and areas of research for optimizing the use of sign language in instruction.

    2014-02-01

    Open resection arthroplasty of the sternoclavicular (SC) joint has historically provided good long-term results in patients with symptomatic osteoarthritis of the SC joint. However, the procedure is rarely performed because of the risk of injury to vital mediastinal structures and concern regarding postoperative joint instability. Arthroscopic decompression of the SC joint has therefore emerged as a potential treatment option because of many recognized advantages including minimal tissue dissection, maintenance of joint stability, avoidance of posterior SC joint dissection, expeditious recovery, and improved cosmesis. There are, however, safety concerns given the proximity of neurovascular structures. In this article we demonstrate a technique for arthroscopic SC joint resection arthroplasty in a 26-year-old active man with bilateral, painful, idiopathic degenerative SC joint osteoarthritis. This case also highlights the pearls and pitfalls of arthroscopic resection arthroplasty for the SC joint. There were no perioperative complications. Four months postoperatively, the patient had returned to full activities, including weightlifting, without pain or evidence of SC joint instability. One year postoperatively, the patient showed substantial improvements in the American Shoulder and Elbow Surgeons score; Single Assessment Numeric Evaluation score; Quick Disabilities of the Arm, Shoulder and Hand score; and Short Form 12 Physical Component Summary score over preoperative baseline values.

    Full Text Available Objective: Placing gold implants in the upper eyelids is a widely accepted method in lagophthalmos treatment. Gold can be obtained as custom-made or from medical firms, as well as from jewelers. This review intends to share the algorithm applied in our clinic, to help avoid undesirable postoperative results. Material and Methods: Between 2012 and 2014, seven patients were planned to undergo gold implant surgery for lagophthalmos. In each of the seven cases preoperative weight tests were performed in upright-seated position, incision site and implant weights were measured, and the determined weights were tested twice, sterilization was applied. Results: None of the patients showed any early or late complications. Complete closure of the eyelids was achieved. Aesthetic evaluations of the patients were found to be better than the physician’s evaluations. Conclusion: The weight of the gold is the most important factor that determines the success of the implant treatment. It is possible to reduce postoperative morbidity and increase success by adhering to simple preoperative criteria when gold is obtained from jewelers, a cost-effective method that yields high patient satisfaction.

    1980-01-01

    A joint study has been conducted by NASA and Army installations collocated in a dense forest in southwestern Mississippi in order to determine the technical and economic feasibility of using wood waste as a renewable energy source. The study has shown that, with proper forest management, the timber on government lands could eventually support the total energy requirements of 832 billion Btu/yr. Analysis of the current conversion technologies indicates that the direct combustion spreader stoker approach is the best demonstrated technology for this specific application. The economics of the individual powerplants reveal them as attractive alternatives to fossil fueled plants. Environmental aspects are also discussed.

    The 1994 Pacific Northwest Loads and Resources Study establishes the Bonneville Power Administration`s (BPA) planning basis for supplying electricity t6 BPA customers. The Loads and Resources Study is presented in two documents: (1) this technical appendix detailing loads and resources for each major Pacific Northwest generating utility; and (2) a summary of Federal system and Pacific Northwest region loads and resources. This analysis updates the 1993 Pacific Northwest Loads and Resources Study Technical Appendix published in December 1993. This technical appendix provides utility specific information that BPA uses in its long-range planning. It incorporates the following for each utility: (1) electrical demand-firm loads; (2) generating resources; and (3) contracts both inside and outside the region. This document should be used in combination with the 1994 Pacific Northwest Loads and Resources Study, published in December 1994, because much of the information in that document is not duplicated here. This BPA planning document incorporates Pacific Northwest generating resources and the 1994 medium load forecast prepared by BPA. Each utility`s forecasted future firm loads are subtracted from its existing resources to determine whether it will be surplus or deficit. If a utility`s resources are greater than loads in any particular year or month, there is a surplus of energy and/or capacity, which the utility can sell to increase revenues. Conversely, if its firm loads exceed available resources, there is a deficit of energy and/or capacity, and additional conservation, contract purchases, or generating resources will be needed to meet the utility`s load.

    Objective: To establish an assessment system, including indexes and scoring methods, that can be used for performance evaluation of the provincial blindness prevention technical guidance group properly and effectively . Methods: The indexes and scoring methods were set based on the core content of The " National Plan of Prevention and Treatment of Blindness (2012-2015)" , the specific requirement and target of the World Health Organization (WHO) "For the General Eye Health: Global plan of Action (2014-2019)" , and the current situation of the China's provinces and autonomous regions. These indexes should be of effectiveness, feasibility, comparability, guidance and advancing. Formed by a literature review of candidate indicators, the framework of the system is built by qualitative assessment. With the Delphi method, the system was further revised and improved. Empirical pilot study was then used to prove the feasibility, followed by the final qualitative analysis that establish the " Chinese provincial Blindness prevention technical guidance group performance evaluation system" . Results: Through the literature review and qualitative assessment, a six dimensional system framework was built, including 6 first-level indicators, 16 second-level indicators, and 29 third-level indicators through Delphi method evaluation. With the variation coefficient method, the coeffiences of the first-level index weight were calculated as: Organization and management 0.15, Development and implementation of blindness prevention plans 0.15, Implementation of blindness prevention projects 0.14, Training 0.17, Health education 0.18, and Cooperation and exchanges 0.21. The specific scoring method for this system is confirmed as: data and files check, field interview, and record interview, sampling investigation. Empirical pilot study was conducted in the Jilin, Guizhou and Gansu provinces, and the self-assessment results from local experts were consistent with the scores from the systems

    Chiou, Wen-Bin; Yang, Chao-Chin

    2006-01-01

    In this study, modeling advantage that depicts the likelihood of a teacher model being imitated by students over other competing models in a particular class was developed to differentiate the rival modeling of two kinds of teachers (the technical teachers vs. the lecturing teachers) between college students' learning styles and occupational stereotypes in the collaborative teaching of technical courses. Results of a one-semester longitudinal study indicated that the students perceived a greater modeling advantage of the technical teachers than that of the lecturing teachers. Both the students' learning styles and occupational stereotypes were in accordance with those teachers as their role models. In general, the impact of the teachers' learning styles and occupational stereotypes on students appeared to be mediated by the teachers' modeling advantage. Administrators and curriculum designers should pay attention to the fact that the technical teachers appeared to exhibit greater modeling effects than the lecturing teachers in collaborative teaching.

  12. Regional case studies--Africa.

    Science.gov (United States)

    Prentice, Andrew M

    2009-01-01

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

  13. Leishmaniasis in dogs: Case study

    Directory of Open Access Journals (Sweden)

    Aleksić Jelena

    2009-01-01

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

    We have developed novel biodegradable polymer implants by using the rapid prototyping technology fused deposition modeling. Early results of a clinical pilot study for cranioplasty are presented. Five patients with the diagnosis of chronic subdural hematoma were included in the study. After trephination and evacuation of the subdural hematoma, burr holes (diameter, 14 mm) were closed using a biodegradable implant made of polycaprolactone. Implants were computer designed with an upper rim diameter of 16 mm and a 14 mm body diameter with a fully interconnected, honeycomb-like architecture of 400 to 600 microm in pore size. Postoperative computed tomographic scans indicated that the plugs were stably anchored in the osseous host environment with no fluid collection detectable. The postoperative course was uneventful, and patients were discharged after 5 days. Follow-up scans after 3, 6, and 12 months showed that the implants were well integrated in the surrounding calvarial bone with new bone filling the porous space. These novel polymer scaffolds made of the slow-degrading material polycaprolactone represent a suitable implant for closure of post-trephination defects.

  15. Case studies--ergonomics in projects.

    Pikaar, Ruud N

    2012-01-01

    The aim of a series of sessions on Company Case Studies, is to learn from practical experiences, to give feed back to researchers on applicability of theories, methods and techniques, and last but not least, to market ergonomics. In order to learn from case material, reports need to be easy accessible and well structured. System ergonomics provides such a structure. Usually a project is not done twice, i.e. with and without ergonomics. Therefore, it is not possible to make comparisons and determine the impact of ergonomics directly. A different approach is needed. It has been suggested at the IEA2006 World Congress, to compile a database of published case studies, each case to be reported in a fixed report format and critically reviewed to enable generalizing the outcomes. This paper proposes such a format. At the IEA2012 World Congress 40 case studies have been accepted, representing applied ergonomics cases in manufacturing, process industries, aviation and logistic systems.

    Iwakabe, Shigeru; Gazzola, Nicola

    2009-07-01

    Recent developments in case study methodology reflect a rising interest that clinicians and researchers share in building a clinically useful and empirically sound knowledge base from single-case studies. The present article describes three types of single-case studies (clinical, experimental, systematic) and examines their potential contributions to psychotherapy research. It then lays out three ways in which single-case studies can be aggregated and synthesized to enhance clinical understanding: (a) a case database that allows clinicians to efficiently search for relevant cases, (b) a metasynthesis of single-case studies that integrates common themes across similar cases, and (c) an individual case comparison method in which closely matched cases are compared to identify both therapeutic and hindering processes.

    Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

    Full Text Available The fact that web based distance learning concept has recently gained more and more significance has required the establishment of virtual campuses at universities and the provision of synchronous and asynchronous education facilities to be used in these campuses. While applying distance learning methods, the universities should adopt genuine learning management systems that could reflect their own characteristics and meet their own needs which are also adaptable to mid and long-term technological changes. The universities should also have synchronous education facilities integrated to the system.1. MethodologyAs is required by the nature of the research problem itself, this study bears a qualitative feature. “Action research”, which is one of the qualitative research approaches has been used in this study. Documents and observations have been used as data collection instruments. The diaries of the students who participated to the research during the design of the system have been analysed using document analysis technique. The research has been conducted with the participation of 14 M.A. students from Karadeniz Technical University, Fatih Faculty of Education, Department of Computer and Instructional Technologies during 2008-2009 spring term. During the research students‟ individual diaries, have been coded and qualitatively analysed. The results of the qualitative analysis indicate similar and different cases experienced by two different students groups during the study.2. System Design ProcessIt has turned out that specific software with synchronous and asynchronous features should be employed in order to ensure effective use of the present distance learning system. The preparation of synchronous and asynchronous chapters has required different coding and design features therefore two different groups have been formed.The synchronous and asynchronous working groups have made a literature review regarding their own fields of study.

    Background Communication and teamwork failures have frequently been identified as the root cause of adverse events and complications in surgery. Few studies have examined contextual factors that influence teams’ non-technical skills (NTS) in surgery. The purpose of this prospective study was to identify and describe correlates of NTS. Methods We assessed NTS of teams and professional role at 2 hospitals using the revised 23-item Non-TECHnical Skills (NOTECHS) and its subscales (communication, situational awareness, team skills, leadership and decision-making). Over 6 months, 2 trained observers evaluated teams’ NTS using a structured form. Interobserver agreement across hospitals ranged from 86% to 95%. Multiple regression models were developed to describe associations between operative time, team membership, miscommunications, interruptions, and total NOTECHS and subscale scores. Results We observed 161 surgical procedures across 8 teams. The total amount of explained variance in NOTECHS and its 5 subscales ranged from 14% (adjusted R2 0.12, p<0.001) to 24% (adjusted R2 0.22, p<0.001). In all models, inverse relationships between the total number of miscommunications and total number of interruptions and teams’ NTS were observed. Conclusions Miscommunications and interruptions impact on team NTS performance. PMID:28137931

    2017-01-01

    Full Text Available Background: Case studies are core constructs used in information management research. A persistent challenge for business, information management and social science researchers is how to select a representative sample of cases among a population with diverse characteristics when convenient or purposive sampling is not considered rigorous enough. The context of the study is post-school education, and it involves an investigation of quantitative methods of clustering the population of public technical and vocational education and training (TVET colleges in South Africa into groups with a similar level of maturity in terms of their information systems.Objectives: The aim of the study was to propose an evidence-based quantitative method for the selection of cases for case study research and to demonstrate the use and usefulness thereof by clustering public TVET colleges.Method: The clustering method was based on the use of a representative characteristic of the context, as a proxy. In this context of management information systems (MISs, website maturity was used as a proxy and website maturity model theory was used in the development of an evaluation questionnaire. The questionnaire was used for capturing data on website characteristics, which was used to determine website maturity. The websites of the 50 public TVET colleges were evaluated by nine evaluators. Multiple statistical techniques were applied to establish inter-rater reliability and to produce clusters of colleges.Results: The analyses revealed three clusters of public TVET colleges based on their website maturity levels. The first cluster includes three colleges with no websites or websites at a low maturity level. The second cluster consists of 30 colleges with websites at an average maturity level. The third cluster contains 17 colleges with websites at a high maturity level.Conclusion: The main contribution to the knowledge domain is an innovative quantitative method employing a

    Based on seven case studies of buildings that underwent different degrees of moisture and mold damage remediation, we aimed to develop methodology for assessment of the success of the remediation process. Methods used in gauging the success included technical monitoring of performance of building structures and heating, ventilation and air conditioning (HVAC) systems, microbial monitoring of indoor air quality (IAQ), and health effects studies of building occupants. The assessment was based on measurable change in the situations before and after remediation. Based on technical monitoring, remediation was successful in three cases, with partial improvement noted in three cases, whereas no remediation was conducted in one case. Based on microbial monitoring, improvement was detected in one, partial improvement in two and no improvement in two cases, whereas no follow-up was conducted in two cases. Health effect studies (mainly self-reported health status) showed improvement in one case, partial improvement in two cases, and no improvement in two cases, whereas no follow-up was conducted in one case, and in one case, follow-up failed due to low response rate. The results illustrate that it is possible to monitor the effects of remediation using various metrics. However, in some cases, no improvement could be observed in IAQ or occupant health, even if the remediation was considered technically successful, i.e. the remediation was fully completed as recommended. This could be due to many reasons, including: 1) all damage may not have been addressed adequately; 2) IAQ or health may not have been perceived improved regardless of remediation; and/or 3) the methods used may not have been sensitive/specific enough to detect such improvement within the 6-12 months follow-up periods after completion of the remediation. There is a need to further develop tools for monitoring and assessment of the success of moisture damage remediation in buildings.

    Western Research Institute, in conjunction with the Electric Power Research Institute, Foster Wheeler International, Inc. and the US Department of Energy, has undertaken a research and demonstration program designed to examine the market potential and the technical feasibility of ash use options for PFBC ashes. Ashes from the Foster Wheeler Energia Oy pilot-scale circulating PFBC tests in Karhula, Finland, combusting (1) low-sulfur subbituminous and (2) high-sulfur bituminous coal, and ash from the AEP's high-sulfur bituminous coal-fired bubbling PFBC in Brilliant, Ohio, were evaluated in laboratory and pilot-scale ash use testing at WR1. The technical feasibility study examined the use of PFBC ash in construction-related applications, including its use as a cementing material in concrete and use in cement manufacturing, fill and embankment materials, soil stabilization agent, and use in synthetic aggregate production. Testing was also conducted to determine the technical feasibility of PFBC ash as a soil amendment for acidic and sodic problem soils and spoils encountered in agricultural and reclamation applications. The results of the technical feasibility testing indicated the following conclusions. PFBC ash does not meet the chemical requirements as a pozzolan for cement replacement. However, it does appear that potential may exist for its use in cement production as a pozzolan and/or as a set retardant. PFBC ash shows relatively high strength development, low expansion, and low permeability properties that make its use in fills and embankments promising. Testing has also indicated that PFBC ash, when mixed with low amounts of lime, develops high strengths, suitable for soil stabilization applications and synthetic aggregate production. Synthetic aggregate produced from PFBC ash is capable of meeting ASTM/AASHTO specifications for many construction applications. The residual calcium carbonate and calcium sulfate in the PFE3C ash has been shown to be of

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

  19. Risk Management from Corporate and FM Perspectives: Two case studies

    DEFF Research Database (Denmark)

    2012-01-01

    Purpose: To investigate how Risk Management (RM) is perceived and practiced in Facilities Management (FM) and corporate management and to evaluate the potential benefits of an increased application. Theory: RM is a generic management discipline, but apparently it has not achieved the attention...... it deserves in FM. Application of RM in FM could help to increase the strategic importance and awareness of FM among corporate managers. Approach: A preliminary study with expert interviews was initially conducted followed by a main study with an interview survey in two Danish case companies - a real estate...... company and a consulting engineering company. Findings: The research showed that RM was applied in both companies to a higher degree than initially expected, but often using other terminology. The real estate company had a much stronger focus on RM in relation to the technical aspects of real estate...

  3. Energy portfolio of Iran: A case study of solar desalination

    Science.gov (United States)

    Besharati, Adib

    Energy plays a very important role in the economic development of a country such as Iran where industrial progress and higher living standards increase demand for energy. Iran is one of the countries in the world that simultaneously produces and consumes large amounts of energy. Because of its geographic latitude and weather conditions, Iran has the potential to develop and use of both fossil and renewable energy sources. In South Iran, there are huge oil and gas resources, and at the same time high potential of solar radiation. However, at the present large-scale utilization, solar energy is prohibitively expensive for Iran. Therefore, this study investigates an economical way to utilize solar energy in a meaningful way for Iran. One of the possible uses of solar energy that is both economical and technically feasible is desalination of water using solar energy. People in South Iran live in different areas with relatively low population density. One of the critical problems in those areas is a lack of clean drinking water. As a result, there is an urgent need to investigate ways to produce clean water from the saltwater. Therefore, the present study conducts a case study of solar desalination in south Iran using solar. Different desalination methods, such as humidification dehumidification by using a solar collector, and reverse osmosis, are discussed. In the case study, a prototype desalination plant was considered and both technical and economic aspects of the plant were investigated in details. The results showed higher productivity of drinking water in reverse osmosis method for south Iran.

    2016-01-01

    Full Text Available Background. Polyorchidism, alternatively supernumerary testes (SNT, is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery’s body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

    Full Text Available This India is the Fifth largest producer of Electricalenergy in the world. Despite such achievements the gapbetween demand and supply of electrical energy is increasingevery year and power sector is highly capital – intensive. Thusthe deficit in installed capacity was nearly 10000MWper year.So the gap between demand and supply is continuouslyincreasing day by day. An energy audit is a study of a plant orfacility to determine how and where energy is used and toidentify methods for energy savings. The opportunities lie inthe use of existing renewable energy technologies, greaterefforts at energy efficiency and the dissemination of thesetechnologies and options. This thesis provides an overview of ageneral energy conservation measures (ECMs that can becommonly recommended for NIT Hamirpur. It should be notedthat the Energy auidut presented in this paper does not pretendto be exhaustive nor comprehensive. It provides merely toindicate some of the options that energy auditor can considerwhen performing an analysis of this institute. Energyconservation and exploration of new energy avenues are thewell accepted solution to fulfil the demand in future. The totalcost of energy plays a vital role in determining the product costof a commodity. Therefore the identification of potential energysavings and implementation for a given institutional facility isunimportant to ensure its competitive advantage over otherinstitute. This paper work presents such energy saving methodsin a methodological approach, experienced during a detailedenergy audit of NIT Hamirpur.

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient``s high risk of strokes and hemorrhaging prompted investigation by a {sup 99}mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome.

    Full Text Available Modern educational technologies are based on competence approach and focus on the future professional activity. Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

    1980-10-01

    The rapid growth of power systems to meet the ever increasing demand for energy has cast a great challenge upon the power system engineer. It devolves on the engineer to technically and economically analyse the various plans before him and assess their relative merits in order to ensure reliable and economical operations of power systems. This, in turn, calls for rigorous and accurate modelling of power systems and their analysis. As a first step, load flow studies form a vital part of system planning and operational studies. There is always a need to improve the technique of analysing the load flow problem and for its accurate and quick analysis. A computer program was developed in CPRI using Newton Raphson decoupled approach which may be of use to various electricity boards.

    Anomalous portal vein (PV) branching of the donor liver is uncommon and usually makes two, or rarely, more separate PV branches at the right liver graft. Autologous PV Y-graft interposition has long been regarded as the standard procedure, but is currently replaced with the newly developed technique of conjoined unification venoplasty (CUV) due to its superior results. Herein, we presented a case of CUV application to three PV openings of a right liver graft. The recipient was a 32-year-old male patient with hepatitis B virus-associated liver cirrhosis. The living liver donor was his 33-year-old sister who had a type III PV anomaly, but the right posterior PV branch was bifurcated early into separate branches of the segments VI and VII, thus three right liver PV branches were cut separately. We used the CUV technique consisting of placement of a small vein unification patch between three PV orifices, followed by overlying coverage with a crotch-opened autologous portal Y-graft. The portal Y-graft was excised and its crotches were incised to make a wide common orifice. Three bidirectional running sutures were required to attach the crotch-opened autologous portal Y-graft. After portal reperfusion, the conjoined PV portion bulged like a tennis ball, providing a wide range of alignment tolerance. The patient recovered uneventfully from the liver transplantation operation. The CUV technique enabled uneventful reconstruction of triple donor PV orifices. Thus, CUV can be a useful and effective technical option for reconstruction of right liver grafts with various anomalous PVs.

    This report summarizes the results of the study program to assess the benefits of nonlinear analysis methods in Light Water Reactor (LWR) component designs. The current study reveals that despite its increased cost and other complexities, nonlinear analysis is a practical and valuable tool for the design of LWR components, especially under ASME Level D service conditions (faulted conditions) and it will greatly assist in the evaluation of ductile fracture potential of pressure boundary components. Since the nonlinear behavior is generally a local phenomenon, the design of complex components can be accomplished through substructuring isolated localized regions and evaluating them in detail using nonlinear analysis methods.

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

    Historically, effectiveness of community collaborative prevention efforts has been mixed. Consequently, research has been undertaken to better understand the factors that support their effectiveness; theory and some related empirical research suggests that the provision of technical assistance is one important supporting factor. The current study examines one aspect of technical assistance that may be important in supporting coalition effectiveness, the collaborative relationship between the technical assistance provider and site lead implementer. Four and one-half years of data were collected from technical assistance providers and prevention team members from the 14 community prevention teams involved in the PROSPER project. Spearman correlation analyses with longitudinal data show that the levels of the collaborative relationship during one phase of collaborative team functioning associated with characteristics of internal team functioning in future phases. Results suggest that community collaborative prevention work should consider the collaborative nature of the technical assistance provider - prevention community team relationship when designing and conducting technical assistance activities, and it may be important to continually assess these dynamics to support high quality implementation.

    Krosman, Kazimierz; Sosnowski, Janusz

    2016-09-01

    This paper presents software methods of improving fault tolerance in embedded systems. These methods have been adapted to a telemetry system dedicated to tracking vehicles for logistics purposes. The developed telemetry system allows us to monitor vehicle position and some technical parameters via GSM communication. It comprises the capability of remote software reconfiguration. To evaluate dependability of the system we use a fault injection technique based on simulating bit-flip errors within memory cells. For this purpose an original testbed has been developed. It provides not only the capability of disturbing internal state of the tested system (via JTAG interface) but also the possibility of controlling system input states and observing its behavior (in particular output signals) according to specified test scenarios. The whole test process is automatized. The paper presents a case study related to a commercial product but the described methodology and techniques can be extended for other embedded systems.

    This article reviews the significance of the microbiome in cancer epidemiology, mechanistic and technical challenges in the field, and characterization of the microbiome in different tumor types to identify biomarkers of risk, progression, and prognosis. Publications on the microbiome and cancer epidemiology were reviewed to analyze sample collection and processing, microbiome taxa characterization by 16S ribosomal RNA sequencing, and microbiome metabolite characterization (metabotyping) by nuclear magnetic resonance and mass spectrometry. The analysis identified methodology types, research design, sample types, and issues in integrating data from different platforms. Aerodigestive cancer epidemiology studies conducted by different groups demonstrated the significance of microbiome information in developing approaches to improve health. Challenges exist in sample preparation and processing (eg, standardization of methods for collection and analysis). These challenges relate to technology, data integration from "omics" studies, inherent bias in primer selection during 16S ribosomal RNA sequencing, the need for large consortia with well-characterized biospecimens, cause and effect issues, resilience of microbiota to exposure events (requires longitudinal studies), and expanding studies for fungal and viral diversity (most studies used bacterial 16S ribosomal RNA sequencing for microbiota characterization). Despite these challenges, microbiome and cancer epidemiology studies are significant and may facilitate cancer risk assessment, diagnosis, and prognosis. In the future, clinical trials likely will use microbiota modifications to improve the efficacy of existing treatments.

    Full Text Available With a semi-arid Mediterranean climate and viticulture vocation, the tray of Mostaganem (North-West of Algeria has become a region of great crops. Subject to increase mechanization and inappropriate tillage practices, farm lands are exposed to erosion that seriously weighs the physical and socio-economic contexts. An itinerary technique (cereal is chosen to study along the slope, surface and deep structural changes of soil, humidity and the fine particles (<2 μm. Thus, consideration of the surface shows a strong soil erodibility partly linked to the action of implements and a rain erosivity accentuated by lack of vegetation in the rainy season.Culural profiles observations show the small depth of tillage affecting mostly superior horizon. Average horizon, wet, rich in fine particles and barely reached by tools impedes any move to lower horizon which is very compact without variability. With this kind of technical itinerary, fine elements losses estimated to (3 t/ha/year result closely from the characteristics of the physical environment but also the conditions of its exploitation. In case of more important spatial-temporal unit’s extrapolation, the consequences will be even more harmful if improvement actions are not undertaken.

    Full Text Available Over the last forty years, case study research has undergone substantial methodological development. This evolution has resulted in a pragmatic, flexible research approach, capable of providing comprehensive in-depth understanding of a diverse range of issues across a number of disciplines. Change and progress have stemmed from parallel influences of historical transformations in approaches to research and individual researcher's preferences, perspectives, and interpretations of this design. Researchers who have contributed to the development of case study research come from diverse disciplines with different philosophical perspectives, resulting in a variety of definitions and approaches. For the researcher new to using case study, such variety can create a confusing platform for its application. In this article, we explore the evolution of case study research, discuss methodological variations, and summarize key elements with the aim of providing guidance on the available options for researchers wanting to use case study in their work.

    Science.gov (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    Chinese county hospitals have been excessively enlarging their scale during the healthcare reform since 2009. The purpose of this paper is to examine the technical efficiency and productivity of county hospitals during the reform process, and to determine whether, and how, efficiency is affected by various factors. 114 sample county hospitals were selected from Henan province, China, from 2010 to 2012. Data envelopment analysis was employed to estimate the technical and scale efficiency of sample hospitals. The Malmquist index was used to calculate productivity changes over time. Tobit regression was used to regress against 4 environmental factors and 5 institutional factors that affected the technical efficiency. (1) 112 (98.2%), 112 (98.2%) and 104 (91.2%) of the 114 sample hospitals ran inefficiently in 2010, 2011 and 2012, with average technical efficiency of 0.697, 0.748 and 0.790, respectively. (2) On average, during 2010-2012, productivity of sample county hospitals increased by 7.8%, which was produced by the progress in technical efficiency changes and technological changes of 0.9% and 6.8%, respectively. (3) Tobit regression analysis indicated that government subsidy, hospital size with above 618 beds and average length of stay assumed a negative sign with technical efficiency; bed occupancy rate, ratio of beds to nurses and ratio of nurses to physicians assumed a positive sign with technical efficiency. There was considerable space for technical efficiency improvement in Henan county hospitals. During 2010-2012, sample hospitals experienced productivity progress; however, the adverse change in pure technical efficiency should be emphasised. Moreover, according to the Tobit results, policy interventions that strictly supervise hospital bed scale, shorten the average length of stay and coordinate the proportion among physicians, nurses and beds, would benefit hospital efficiency.

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

    Full Text Available I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking.  Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks.  Students then develop their own case study, integrating ethical components.  I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." and want future physicians grounded in a sense of how their actions relate to the greater good.

  9. Cryostat design case studies, principles and engineering

    CERN Document Server

    2016-01-01

    This book enables the reader to learn the fundamental and applied aspects of practical cryostat design by examining previous design choices and resulting cryostat performance. Through a series of extended case studies the book presents an overview of existing cryostat design covering a wide range of cryostat types and applications, including the magnet cryostats that comprise the majority of the Large Hadron Collider at CERN, space-borne cryostats containing sensors operating below 1 K, and large cryogenic liquid storage vessels. It starts with an introductory section on the principles of cryostat design including practical data and equations. This section is followed by a series of case studies on existing cryostats, describing the specific requirements of the cryostat, the challenges involved and the design choices made along with the resulting performance of the cryostat. The cryostat examples used in the studies are chosen to cover a broad range of cryostat applications and the authors of each case are ...

  11. Technical and economic feasibility study of a Frond type wave power generator

    2003-07-01

    This report describes the first stage of the development of a Frond type wave generator by the Engineering Business (EB) in collaboration with the University of Lancaster Engineering Department. The EB Frond concept is a sea-bed reacting, surging machine consisting of a near-surface collector mounted on an arm pivoted near the seabed. The study had six main elements (investigation, physical and mathematical modelling, site characterisation, design review and cost study). The investigation phase involved a study of wave properties and behaviour, while physical models were tested in a wave tank. A mathematical model was developed and used to assess the design's power output. The characteristics of a suitable site for EB Frond generators were determined and the process of identifying possible sites for a demonstrator machine was begun. The mechanical and system arrangement of the design were evaluated and modified. The effects of varying the installation's input parameters (e.g. wave environment factors) were examined using an energy cost model whose output is energy production and cost. It was concluded that the Frond principle was technically viable though there were some remaining engineering and other application problems. Cost modelling suggested that the EB Frond system had potential for long-term commercial prospects. The report recommends the construction and testing of an intermediate scale model with more realistic wave conditions.

  12. SYNONYMS IN ACTION: A CASE STUDY

    Full Text Available This paper discusses what the methods of conversation analysis (CA might have to offer the study of linguistic synonymy. It takes as a case study two items commonly held to be synonyms -'actually' and 'in fact'- and shows considerable differences between the two in their interactional implementation: they are implicated in the prosecution of differing courses of action. Such cases argue that it is analytically more profitable to consider what a lexical item does in the context of talk than what it means.

    decisions based on indicators. In essence, visualizing indicators and their dependencies can communicate the information to the stakeholders efficiently if done correctly, or mislead them if not done properly. In this paper we present results of a case study conducted in a unit of Ericsson. During the case...... study we identified the main requirements for methods for visualizing the indicators, developed these visualizations and conducted a series of interviews evaluating them. The results show that the dashboard presentation is the best solution, but that the simple, tabular visualizations are next best...

    Repurposing Legacy Data: Innovative Case Studies takes a look at how data scientists have re-purposed legacy data, whether their own, or legacy data that has been donated to the public domain. Most of the data stored worldwide is legacy data-data created some time in the past, for a particular purpose, and left in obsolete formats. As with keepsakes in an attic, we retain this information thinking it may have value in the future, though we have no current use for it. The case studies in this book, from such diverse fields as cosmology, quantum physics, high-energy physics, microbiology,

    Denne konklusion sammenfatter hovedtrækkene af de gennemførte case studies i WorkAble-projektet. Vigtige pointer er, at unge på tværs af de forskellige case studies har vanskeligt ved at blive hørt og taget alvorligt. I stedet spises de af med "realistisk vejledning" eller dårlige uddannelses- og...... arbejdstilbud. Konklusionen foreslår at give unge mere tid til at træffe de alvorlige valg vedr. deres fremtid ved at indføre et refugium, som i tankegang minder om Eriksons ungdomsmoratorium....
