    The technical development of clean energy including the utilization of solar energy was begun in 1973 at the time of the oil crisis, and about 20 years elapsed. Also in Japan, the electric power buying system by electric power companies for solar light electric power and wind electric power has been started in 1992, namely their value as a merchandise was recognized. As for these two technologies, the works of making the international standards and JIS were begun. The range of clean energy or natural energy is wide, and its kinds are many. The utilization of solar heat and the electric power generation utilizing waves, tide and geotherm already reached the stage of practical use. Generally in order to practically use new energy, the problem of price must be solved, but the price is largely dependent on the degree of spread. Also the reliability, durability and safety must be ensured, and the easiness of use, effectiveness and trouble-saving maintenance and operation are required. For the purpose, it is important to packaging those skillfully in a system. The cases of intelligent natural energy systems are shown. Solar light and wind electric power generation systems and the technology of transporting clean energy are described. (K.I.)

    One of the constant challenges facing the research community is the identification of technology needs 5 to 15 years from now. A look back into history indicates that the forces driving natural gas research have changed from decade to decade. In the 1970s research was driven by concerns for adequate supply; in the 1980s research was aimed at creating new markets for natural gas. What then are the driving forces for the 1990s? Recent reports from the natural gas industry have helped define a new direction driven primarily by market demand for natural gas. A study prepared by the Interstate Natural Gas Association of America Foundation entitled ''Survey of Natural Research, Development, and Demonstration RD ampersand D Priorities'' indicated that in the 1990s the highest research priority should be for natural gas utilization and that technology development efforts should not only address efficiency and cost, but environmental and regulatory issues as well. This study and others, such as the report by the American Gas Association (A.G.A.) entitled ''Strategic Vision for Natural Gas Through the Year 2000,'' clearly identify the market sectors driving today's technology development needs. The biggest driver is the power generation market followed by the industrial, transportation, appliance, and gas cooling markets. This is best illustrated by the GRI 1994 Baseline Projection on market growth in various sectors between the year 1992 and 2010. This paper highlights some of the recent technology developments in each one of these sectors

    A one-year technology-transfer project involving ERDA installations and Hawaii consisted of sending teams from the Lawrence Livermore Laboratory on week-long field trips every two months to test the effectiveness of different methods of transferring technology information from federal sources to civilian clients. The team was questioned primarily on non-energy matters, and the energy questions asked related mostly to individuals or small industries. The team responed to all questions and found that a wide range of knowledge was more effective than having a sequence of experts. Hawaiians considered current major ERDA projects to be irrelevant to their needs. The team was most successful on a one-to-one basis because large groups and state agencies tend to be more policy- than action-oriented. Personal followup was considered essential. The team also learned that their visits generated ten times as many inquiries as were received unsolicited by the laboratory. Most inquiries involved biomass and use of agricultural wastes, solar energy, and transportation. An important contribution of the team's workshops was linking groups to work together on common problems. An appendix lists the subjects of queries and the names and addresses of consortium participants and Hawaiian contacts. (DCK)

    Highlights: • Active and passive solar house technology is integrated in the solar house. • Solar thermal system and solar photoelectric system are measured and analyzed. • Energy balance and energy consumption are analyzed with valuable experimental data. • “Zero energy consumption” is truly achieved with the solar supply rate of 1.19 in winter. - Abstract: An integrated solar house with numerous advanced envelops is designed and constructed to investigate the comprehensive utilization of solar energy, energy efficiency and energy balance, which combines active solar house technology with passive solar house technology including solar photovoltaic system, solar water heating system, direct-gain door and windows. Solar radiation intensity, performance of the photovoltaic system, water temperature, and indoor and outdoor temperature are measured, results of the experiments indicate that solar glass window on the south wall can maintain the average indoor temperature at 21.4 °C in the case of average outdoor temperature at 11.2 °C without any external heat supply. The output current of the solar photovoltaic system shows the same trend as solar radiation intensity. When the intensity is 619.7 W/m 2 , the instantaneous generation power could reach a value of 781.9 W, cumulative capacity throughout the day achieves 4.56 kW h and photovoltaic conversion efficiency 9.8%. When the average intensity throughout a day is 358 W/m 2 , the solar water heating system could help to raise the temperature of 450 L water by 30 °C with its heat collecting efficiency being 37.4%. Through the analysis of the overall energy system in the solar house, it can be derived that this solar house could achieve “zero energy consumption” in winter with the solar supply rate at 1.19.

    We present a cost-utility analysis based on data from the Housing and Health (H&H) Study of rental assistance for homeless and unstably housed persons living with HIV in Baltimore, Chicago and Los Angeles. As-treated analyses found favorable associations of housing with HIV viral load, emergency room use, and perceived stress (an outcome that can be quantitatively linked to quality of life). We combined these outcome data with information on intervention costs to estimate the cost-per-quality-adjusted-life-year (QALY) saved. We estimate that the cost-per-QALY-saved by the HIV-related housing services is $62,493. These services compare favorably (in terms of cost-effectiveness) to other well-accepted medical and public health services.

    The introduction of digital technologies into the nuclear industry has assisted in many ways and made many of the Life Extensions and Uprates a possibility. But with this introduction of digital technologies comes some potentially challenging issues which need to be addressed for ultimate project success. This presentation discusses what a nuclear utility should consider and establish when implementing digital technologies in their plant. Digital technologies have been employed in many safety critical industries such as Aerospace, Pharmaceutical, Oil and Gas, and Chemical. However, nuclear industry implementation of digital technologies has been slow and in many ways tenuous. There are even documented operating experience events in which plant trips/SCRAMs occurred during a digital system implementation. This presentation aims to prevent those issues drawing upon the lessons learned over the past 5 years. Considerations include general challenges to overcome when implementing Digital Technologies, how to justify and execute projects, evaluation of resource knowledge, and the new challenges of Cyber Security.

    In verifying the effectiveness of the deep geothermal resource exploration technology, development is being carried out on a fracture-type reservoir exploration method. The seismic exploration method investigates detailed structures of underground fracture systems by using seismic waves generated on the ground surface. Verification experiments for fiscal 1994 were carried out by selecting the Kakkonda area in which small fracture networks form reservoir beds. Geothermal resources in deep sections (deeper than 2000 m with temperatures higher than 350{degree}C) are promising in terms of amount of the resources, but anticipated with difficulty in exploration and impediments in drilling. To avoid these risks, studies are being progressed on the availability of resources in deep sections, their utilization possibility, and technologies of effective exploration and drilling. This paper summarizes the results of deep resource investigations during fiscal 1994. It also describes such technological development as hot water utilizing power generation. Development is performed on a binary cycle power generation plant which pumps and utilizes hot water of 150 to 200{degree}C by using a downhole pump. The paper also reports development on element technologies for hot rock power generation systems. It also dwells on development of safe and effective drilling and production technologies for deep geothermal resources.

    The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

    Since its inception 40 years ago, NASA's Technology Transfer Program has led the way for our nation to benefit from cutting-edge aerospace technologies. In addition to contributing to U.S. economic growth, these technologies are improving the quality of life on Earth while finding new ways to protect and preserve it. NASA's research and development efforts have advanced areas in medicine, communications, manufacturing, computer technology, and homeland security. These breakthroughs, translated into commercial products, are enhancing the lives of Americans everywhere. When a congressional mandate led NASA to develop the Scientific and Technical Information (STI) Program, the Agency began a wide dissemination of its research and development results. In doing so, NASA recognized that many of its technologies were transferable to industry for the development of commercial products. As a result, the Technology Utilization Program was born in 1962. The successful program went through several changes over the years, as its philosophy, mission, and goals adapted into the Technology Transfer Program we know today. The program strives to make the latest technologies available to industry as soon as they are developed. Each year, NASA's Spinoff publication showcases new products and services resulting from commercial partnerships between NASA and private industry. In the 2002 issue, the NASA field centers reflect upon the growth that has made these innovations available to the public. The Research and Development section examines past achievements, current successes, and future goals for each of the ten NASA centers. The Commercial Benefits section proudly highlights 51 new spinoff products, including a heart pump for patients needing a heart transplant, as well as an air purifier that destroys anthrax spores. The Technology Transfer and Outreach section describes the outreach achievements and educational successes made possible through the NASA Commercial Technology Network

  15. Utilizing Internet Technologies in Observatory Control Systems

    2002-12-01

    The 'Internet boom' of the past few years has spurred the development of a number of technologies to provide services such as secure communications, reliable messaging, information publishing and application distribution for commercial applications. Over the same period, a new generation of computer languages have also developed to provide object oriented design and development, improved reliability, and cross platform compatibility. Whilst the business models of the 'dot.com' era proved to be largely unviable, the technologies that they were based upon have survived and have matured to the point were they can now be utilized to build secure, robust and complete observatory control control systems. This paper will describe how Electro Optic Systems has utilized these technologies in the development of its third generation Robotic Observatory Control System (ROCS). ROCS provides an extremely flexible configuration capability within a control system structure to provide truly autonomous robotic observatory operation including observation scheduling. ROCS was built using Internet technologies such as Java, Java Messaging Service (JMS), Lightweight Directory Access Protocol (LDAP), Secure Sockets Layer (SSL), eXtendible Markup Language (XML), Hypertext Transport Protocol (HTTP) and Java WebStart. ROCS was designed to be capable of controlling all aspects of an observatory and be able to be reconfigured to handle changing equipment configurations or user requirements without the need for an expert computer programmer. ROCS consists of many small components, each designed to perform a specific task, with the configuration of the system specified using a simple meta language. The use of small components facilitates testing and makes it possible to prove that the system is correct.

    2015-04-01

    As many as 25 % of homeless persons have pets. To our knowledge, pet ownership has not been studied quantitatively with homeless youth. This study examined pet ownership among 398 homeless youth utilizing two Los Angeles drop-in centers. Twenty-three percent of homeless youth had a pet. The majority of pet owners reported that their pets kept them company and made them feel loved; nearly half reported that their pets made it more difficult to stay in a shelter. Pet owners reported fewer symptoms of depression and loneliness than their non-pet owning peers. Pet ownership was associated with decreased utilization of housing and job-finding services, and decreased likelihood of currently staying in a shelter. These findings elucidate many of the positive benefits of pet ownership for homeless youth, but importantly highlight that pet ownership may negatively impact housing options. Housing and other services must be sensitive to the needs of homeless youth with pets.

    Full Text Available In our fast paced world, using technology allows us to connect with people and assist them in developing healthier lifestyles within their time limits due to families, work, and other responsibilities. The goal of our project was the development of online, technology-based, nutrition, health, and fitness education challenges using social media as a means of helping consumers develop healthy lifestyle changes. Participants completed preassessments and postassessments to determine overall program impact and to self-report perceptions of knowledge gained and practice/behavior change. Results from the challenges indicated participants gained knowledge on nutrition, health and fitness topics while making strides towards lifestyle changes and adoption of healthy habits. Results revealed healthier eating habits were developed and physical activity was increased with many participants losing weight. Ease of participating was the most reported reason for participating in the challenges. To determine “best practice,” varying lengths of time for the challenges from four, seven, and thirteen weeks allowed the educators to derive implications for future programming, including branding, length of the challenge, frequency, and participant behavior change. To remain relevant and reach a greater diversity of populations, educators need to continue to explore and utilize various social media tools.

    Individuals who are homeless or vulnerably housed have a higher prevalence of concurrent disorders, defined as having a mental health diagnosis and problematic substance use, compared to the general housed population. The study objective was to investigate the effect of having concurrent disorders on health care utilization among homeless or vulnerably housed individuals, using longitudinal data from the Health and Housing in Transition Study. In 2009, 1190 homeless or vulnerably housed adults were recruited in Ottawa, Toronto, and Vancouver, Canada. Participants completed baseline interviews and four annual follow-up interviews, providing data on sociodemographics, housing history, mental health diagnoses, problematic drug use with the Drug Abuse Screening Test (DAST-10), problematic alcohol use with the Alcohol Use Disorders Identification Test (AUDIT), chronic health conditions, and utilization of the following health care services: emergency department (ED), hospitalization, and primary care. Concurrent disorders were defined as the participant having ever received a mental health diagnosis at baseline and having problematic substance use (i.e., DAST-10 ≥ 6 and/or AUDIT ≥ 20) at any time during the study period. Three generalized mixed effects logistic regression models were used to examine the independent association of having concurrent disorders and reporting ED use, hospitalization, or primary care visits in the past 12 months. Among our sample of adults who were homeless or vulnerably housed, 22.6% (n = 261) reported having concurrent disorders at baseline. Individuals with concurrent disorders had significantly higher odds of ED use (adjusted odds ratio [AOR] = 1.71; 95% confidence interval [CI], 1.4-2.11), hospitalization (AOR = 1.45; 95% CI, 1.16-1.81), and primary care visits (AOR = 1.34; 95% CI, 1.05-1.71) in the past 12 months over the four-year follow-up period, after adjusting for potential confounders.

    Full Text Available The article describes the approaches to the management of current assets in the enterprises of various industries in economic literature. We discuss theoretical, methodological and applied issues concerning the formation and improvement of the working capital management policy in utility companies, which require further study. The authors propose to assess the policy of working capital management in these enterprises by means of the integrated approach based on the system of reasoned indicators defining the type of working capital management policy. It includes indicators characterizing the policy of working capital management, management of the liquidity of working capital and the policy of financing sources management. The indicators which define the type of the policy of working capital management have been chosen as the most influential for each vector of the improvement of management policy. The range of values is set taking into account the current market conditions for the housing and utilities companies based on theoretical standard values adapted to modern situation. The paper proposes to use an integrated indicator for the evaluation of the policy of working capital management in housing and utilities enterprises. We have substantiated the technique of the integrated assessment of the policy of working capital management in housing and utilities companies. As an example of the application of this indicator, we defined the type of the policy of working capital management in Rostovvodokanal Company. The initial data for the calculation of integrated indicators are the official data on the structure of the balance and financial results of Rostovvodokanal Company during the period from 2012 to 2016. At the Rostovvodokanal Company, it is necessary to bring the type of the policy of working capital management and sources of its financing closer to moderate or conservative type.

    There is a healthy public policy agenda investigating the health impacts of improving living conditions. However, there are few economic evaluations, to date, assessing value for money. We conducted the first cost-effectiveness analysis of a nationwide intervention transferring social and private tenants to new-build social housing, in Scotland. A quasi-experimental prospective study was undertaken involving 205 intervention households and 246 comparison households, over 2 years. A cost-utility analysis assessed the average cost per change in health utility (a single score summarising overall health-related quality of life), generated via the SF-6D algorithm. Construction costs for new builds were included. Analysis was conducted for all households, and by family, adult and elderly households; with estimates adjusted for baseline confounders. Outcomes were annuitised and discounted at 3.5%. The average discounted cost was £18, 708 per household, at a national programme cost of £ 28.4 million. The average change in health utility scores in the intervention group attributable to the intervention were +0.001 for all households, +0.001 for family households, -0.04 for adult households and -0.03 for elderly households. All estimates were statistically insignificant. At face value, the interventions were not value for money in health terms. However, because the policy rationale was the amenity provision of housing for disadvantaged groups, impacts extend beyond health and may be fully realised over the long term. Before making general value-for-money inferences, economic evaluation should attempt to estimate the full social value of interventions, model long-term impacts and explicitly incorporate equity considerations.

    Although hospice volunteer programs contribute to patient care, little is known about their utilization and adaptation of technology. A survey was posted to the Hospice Volunteer Association Web site to assess technology use among volunteer coordinators and volunteers. Results revealed that participants have access to computers, Internet, and e-mail at the hospice agency and routinely use cellular phones and e-mail. Despite the use of technology, communication problems with volunteers hindered the coordinator's ability to manage scheduling, training, and volunteer assignments for patient care. Coordinators and volunteers felt comfortable utilizing technology but were less comfortable using technology in the patients' home. Several areas are identified for development and integration of advanced technology in volunteer programs. Future research is needed to ease technology implementation and increase volunteer acceptance.

    2017-12-01

    Full Text Available An analysis of the current state and trends in the development of the housing and utilities infrastructure in regions of Ukraine is conducted. It is noted that the housing and utilities infrastructure is an important social sector that provides the population, enterprises, and organizations with the necessary housing and public utility services, which significantly influences the development of the economy of the country and its regions. The analysis showed that public utility enterprises remain stably unprofitable both in Ukraine in whole and in its regions. The attention is focused on the fact that the main sources for financing the housing and utilities infrastructure are the state and local budgets, payments of individuals and legal entities for housing and public utility services, investments and loans provided by international financial organizations that make a significant contribution to the financing of the sector under conditions of budget deficit. Summarizing the results of the PEST analysis and SWOT analysis of the development of the housing and utilities infrastructure in regions of Ukraine, the author concludes that there are a significant number of negative reasons for the weak aspects of the functioning of the housing and utilities infrastructure. There identified economic incentives for attracting potential investors to the programs for the development of the housing and public utility sector in the regions, which are based on the legislative consolidation of the basic conditions for effective functioning of the market for housing and public utility services.

    The projects were a series of pilot projects developed for DOE with the intention of transferring pollution prevention technology to private industry. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education program, the microscale cost benefit study, and the Bethel New Life recycling trainee program. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The recycle trainee project provided training for two participants and identified recycling and source reduction opportunities in Argonne`s solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identification of target technologies that were already available, identification of target audiences, and a focus of effort to achieve a limited but defined objective.

    Shah, Arsalan Nisar; Palacios, Miguel; Ruiz, Felipe

    2013-01-01

    The variation in the adoption of a technology as a major source of competitive advantage has been attributed to the wide-ranging strategic foresight and the integrative capability of a firm. These possible areas of competitive advantage can exist in the periphery of the firm's strategic vision and can get easily blurred as a result of rigidness and can permeate in the decision-making process of the firm. This article explores how electric utility firms with a renewable energy portfolio can become strategically rigid in terms of adoption of newer technologies. The reluctance or delay in the adoption of new technology can be characterized as strategic rigidness, brought upon as a result of a firm's core competence or core capability in the other, more conventional technology arrangement. This paper explores the implications of such rigidness on the performance of a firm and consequently on the energy eco-system. The paper substantiates the results by emphasizing the case of Iberdrola S.A., an incumbent firm as a wind energy developer and its adoption decision behavior. We illustrate that the very routines that create competitive advantage for firms in the electric utility industry are vulnerable as they might also develop as sources of competitive disadvantage, when firms confront environmental change and uncertainty. - Highlights: • Present a firm-level perspective on technology adoption behavior among electric utilities. • Firms with mature technology can become rigid towards newer technologies. • Case study analysis of a major electric utility firm. • Implications of ‘technology rigidness’ on the energy eco-system

    Full Text Available Designing of sustainable water systems should be aimed at reducing the consumption of tap water and the use of alternative water sources, such as rainwater and graywater. Therefore, the aim of the researches conducted was to determine the cost-effectiveness of the economic exploitation of rainwater utilization system in single-family house. As a tool for the analysis, the methodology Life Cycle Cost was used. It provides a comparison of different investment options and the opportunity to choose the one that is characterized by the lowest costs over the entire period of exploitation of the object. The research was conducted for four installation variants: the traditional solution and a solution in which rainwater was used for flushing toilets, washing and watering the garden. Variable parameters for calculations applied in the model were, among other things, different number of occupants and different length of exploitation of the installations. Additionally, the study included co-financing for the initial investment, which could be an incentive for residents to undertake this type of installation. The analysis conducted has shown that the systems with the use of rainwater enable significant reductions in the consumption of drinking water, while the variant with the traditional system was a most cost-effective solution only in few cases.

    2012-01-01

    Transforming the housing stock to a low energy performance is a key priority in the context of sustainable development and a post-carbon transition. However, in terms of its practical implementation it, firstly, faces a number of complex institutional barriers, while, secondly, involves a risk of being dominated by a narrow technocratic agenda for energy/carbon reduction that may overtake the socially progressive pursuits of housing policy. Energy efficiency strategies for the residential sector must, therefore, be multidimensional, fully synergised with housing policy, and incorporating the principles of equity, access and a balanced geographical development. This paper discusses a strategic policy framework, which was designed by the United Nations Economic Commission for Europe (UNECE) to address those important needs in international policy. The document – Action Plan for Energy-efficient Housing in the UNECE Region – outlines a number of goals, targets and actions structured at three dimensions: (i) governance and finance, (ii) technological advancement, and (iii) access and affordability. The Action Plan provides a comprehensive and integrated framework, based on which governments can shape their own pathways towards a sustainable low-energy residential sector. - Highlights: ► Residential sector has a large potential for energy and carbon reduction. ► Energy efficiency for housing must be reconciled with socially oriented housing policy. ► Action Plan for Energy-efficient Housing in the UNECE region is presented. ► The Plan offers an integrated framework for sustainable transition to low-energy housing. ► Governance, technology, and equitable access are three key elements of the framework.

    In the fall of 1993, 1 was asked by the Center for National Security Studies (CNSS) of the Los Alamos National Laboratory (LANL) to study the ways in which technology transfer and defense conversion had been accomplished at General Atomics (GA) and Science Applications International Corporation (SAIC) by interviewing Harold Agnew, who had served as director of Los Alamos before becoming president of General Atomics in 1979, and J. Robert Beyster, who had been a staff member at Los Alamos and at General Atomics before founding SAIC in 1969. Harold Agnew readily complied with my request for an interview and also suggested that I talk to Douglas Fouquet, who is in charge of public relations at General Atomics and is their unofficial historian. Robert Beyster was not available for an interview, but, through the courtesy of John C. Hopkins, a former director of CNSS, I was able to interview SAIC`s executive vice president, Donald M. Kerr, who is also a former director at Los Alamos, and Steven Rockwood, a sector vice president at SAIC who was formerly a staff member at the Laboratory Because Agnew, Kerr, and Rockwood are all familiar with LANL, as well as with their respective companies, the interviews becam exercises In comparative analyses of technology transfer. In what follows, I have tried to summarize both the interviews and some of the research which attended them. It is the historian`s hope that by use of comparative institutional analyses, Laboratory administrators may learn something of value in directing their efforts toward the transfer of technology to private industry and other government agencies.

    Chen, ZhiWen; Wang, Mingfeng; Ren, Yongzhi; Jiang, Enchen; Jiang, Yang; Li, Weizhen

    2018-02-01

    Torrefaction is an emerging technology also called mild pyrolysis, which has been explored for the pretreatment of biomass to make the biomass more favorable for further utilization. Dry torrefaction (DT) is a pretreatment of biomass in the absence of oxygen under atmospheric pressure and in a temperature range of 200-300 degrees C, while wet torrrefaction (WT) is a method in hydrothermal or hot and high pressure water at the tempertures within 180-260 degrees C. Torrrefied biomass is hydrophobic, with lower moisture contents, increased energy density and higher heating value, which are more comparable to the characteristics of coal. With the improvement in the properties, torrefied biomass mainly has three potential applications: combustion or co-firing, pelletization and gasification. Generally, the torrefaction technology can accelerate the development of biomass utilization technology and finally realize the maximum applications of biomass energy.

    A San Francisco study conducted in 2008 showed that the permanent supportive housing program, Direct Access to Housing, dramatically decreased the risk of death in people living with HIV. In our study, we compared the health care utilization patterns and HIV-related biological markers of formerly homeless adults with HIV before and during two types of permanent supportive housing: (a) housing with on-site nursing care for residents, and (b) housing without on-site nursing care. Using nearest-neighbor matching with propensity scoring, the difference in outcomes was calculated. In the matched analysis, adjusted for adherence to combination antiretroviral therapy, people housed at sites with nurses had 4.8 fewer emergency department visits per person (SE: 1.53, p < .01), and they had an increased mean CD4+ T cell count (101.14 cells per person [SE: 55.10, p < .05]) compared to those who lived at sites without nurses.

    2015-05-01

    Full Text Available With increased time spent indoors and demand for enhanced comfort levels, energy consumption in homes is rising mostly for cooling, particularly in hot-humid regions. Natural ventilation is seen as an alternative to mechanical cooling as it is totally independent on energy and has been reported to be of high potential. However, little information is available on the utilization of natural ventilation in individual living spaces in different house designs. Therefore, this paper aims to investigate occupants’ utilization of natural ventilation in living spaces under different terrace house designs in hot-humid climate and also the relationship between the openings and occupants’ satisfaction with natural ventilation. Five (5 different terrace house types in Putrajaya, Malaysia with different opening design characteristics were selected for the study. A total of 298 households from these house types were surveyed and results show that occupants mostly open their windows during the daytime to capture breeze from outside despite the fact that they owned air-conditioners. In terms of occupants’ level of satisfaction with indoor ventilation when utilizing natural ventilation, majority rated neither satisfied nor unsatisfied. Further regression analysis reveals that this level of satisfaction is significantly related to opening sizes that are in accordance with the law, duration of opening windows and AC ownership. Findings from this study will shed more light on behavioural pattern of occupants of residential buildings towards natural ventilation provisions and highlight the importance of conforming to the law governing them.

    Schneiders, H.H.

    1995-01-01

    The first part of the paper presents the common perception of technology transfer as a trade relationship rather than a systematic approach to establish a complex technological capacity in a given field. It aims to correct this misperception by introducing some other ideas: (a) the need to support the people, adjust the relevant organizations and establish the capacities to provide the products and services; (b) the typical life cycles of technologies from the initial concept to the final stages of transfer and sustainable dissemination; (c) the needs and expectations of the groups targeted by the technologies for biomass energy utilization. The second part of the paper discusses one example of successful technology transfer: the use of large biomass-burning stoves for food preparation in public institutions and private restaurants in East Africa. The third part of the paper highlights two non-technological barriers to the transfer of biomass energy technologies: (a) weak market forces and business interests and a large number of State activities and projects and (b) conflicting interests of end-users, craftsmen, private and public project partners, which can threaten the success of the attempted technology transfer, even after local adaptation. Finally, suggestions are made for overcoming some of these problems. (author)

    2011-01-01

    We have examined the technologies required to enable Mars Tn-Situ Resource Utilization (ISRU) because our understanding of Mars resources has changed significantly in the last five years as a result of recent robotic missions to the red planet [1-4]. Two major developments, (1) confirmation of the presence of near-surface water in the form of ice in very large amounts at high latitudes by the Phoenix Lander and (2) the likely existence of water at lower latitudes in the form of hydrates or ice in the top one meter of the regolith, have the potential to change ISRU technology selection. A brief technology assessment was performed for the most promising Mars atmospheric gas processing techniques: Reverse Water Gas Shift (RWGS) and Methanation (aka Sabatier), as well as an overview of soil.processing technology to extract water from Martian soil.

    2015-11-01

    Social housing organisations are increasingly installing renewable energy technologies, particularly for the provision of heating and hot water. To meet carbon reduction targets, uptake and installation must allow occupants to use the technology effectively. This paper describes research which investigated the service of installing heat pumps into UK social housing properties, from both landlords' and tenants' experiences. Adopting a user centred design approach, the research was in three phases: an exploration study to investigate landlords' and tenants' experiences of heat pump installation and use; refinement and development of the requirements for improved service delivery, primarily technology introduction and control; and the development and initial evaluation of an information leaflet as a key touchpoint in the service delivery. Recommendations for improved service delivery, to enable heat pumps to be accepted and used more effectively, are presented, as well as reflection on the process of applying user centred design in this context. In a relatively immature area of industry, installations to date have been heavily focused on technical aspects. This paper provides an insight into the human aspects of the service delivery of heat pumps in social housing, providing designers and social housing landlords with insight about how to improve the service.

    The US Department of Housing and Urban Development (HUD)-VA Supportive Housing (VASH) program-the VA's Housing First effort-is central to efforts to end Veteran homelessness. Yet, little is known about health care utilization patterns associated with achieving HUD-VASH housing. We compare health service utilization at the VA Greater Los Angeles among: (1) formerly homeless Veterans housed through HUD-VASH (HUD-VASH Veterans); (2) currently homeless Veterans; (3) housed, low-income Veterans not in HUD-VASH; and (4) housed, not low-income Veterans. We performed a secondary database analysis of Veterans (n=62,459) who received VA Greater Los Angeles care between October 1, 2010 and September 30, 2011. We described medical/surgical and mental health utilization [inpatient, outpatient, and emergency department (ED)]. We controlled for demographics, need, and primary care use in regression analyses of utilization data by housing and income status. HUD-VASH Veterans had more inpatient, outpatient, and ED use than currently homeless Veterans. Adjusting for demographics and need, HUD-VASH Veterans and the low-income housed Veterans had similar likelihoods of medical/surgical inpatient and outpatient utilization, compared with the housed, not low-income group. Adjusting first for demographics and need (model 1), then also for primary care use (model 2), HUD-VASH Veterans had the greatest decrease in incident rates of specialty medical/surgical, mental health, and ED care from models 1 to 2, becoming similar to the currently homeless, compared with the housed, not low-income group. Our findings suggest that currently homeless Veterans underuse health care relative to housed Veterans. HUD-VASH may address this disparity by providing housing and linkages to primary care.

    Various measurements are conducted in an energy-efficient house equipped with a photovoltaic power generation system and actually lived in by people, and matching between the household load and photovoltaic power generation, and the consumption of power, are examined. As the result investigation of power consumption in the house, it is found that 13.31kWh is consumed in the daytime in winter, and 14.15kWh in summer. Thirty-two 153W modules are used, and they produce 12.74kWh in four hours on a fine summer day, which amount nearly satisfies the demand of the household. As for the records during a year beginning in May, 1996, it is found that an annual amount of 4326kWh was generated, with 68% being surplus and 32% consumed for the household. Details of the household consumption were that 49.2% was consumed for house heating and cooling and 34.1% for cooking, the two in total occupying more than 80% of the whole household consumption. Energy-saving behavior is evaluated by comparing the energy-efficient house with some ordinary residential houses in Kumamoto City, and it is found that there is a yearly difference of 104,310 yen in electricity bill or 47% in energy saving effect. 5 refs., 4 figs., 4 tabs.

    The Long-Term Program for Research, Development and Utilization of Nuclear Energy established by the Atomic Energy Commission of Japan asserts that Japan will promote systematic utilization of MOX fuel in LWRs. Based on this Japanese nuclear energy policy, we have been pushing development of MOX fuel technology aimed at future full scale utilization of this fuel in BWRs. In this paper, the main R and D topics are described from three subject areas, MOX core and fuel design, MOX fuel irradiation behaviour, and MOX fuel fabrication technology. For the first area, we explain the compatibility of MOX fuel with UO 2 core, the feasibility of the full MOX core, and the adaptability of MOX design methods based on a mock-up criticality experiment. In the second, we outline the Tsuruga MOX irradiation program and the DOMO program, and suggest that MOX fuel behaviour is comparable to ordinary BWR UO 2 fuel behaviour. In the third, we examine the development of a fully automated MOX bundle assembling apparatus and its features. (author). 14 refs, 11 figs, 3 tabs

    The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the US Department of Energy (DOE) is the development of a highly efficient, environmentally superior, and cost-competitive utility ATS for base-load utility-scale power generation, the GE 7H (60 Hz) combined cycle power system, and related 9H (50 Hz) common technology. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown.

    1998-12-01

    The Mobile Integrated Temporary Utility System (MITUS) integrates portable electrical power along with communications and emergency alarm and lighting capabilities to provide safe, centralized power to work areas that need to be de-energized for decommissioning work. MITUS consists of a portable unit substation; up to twenty portable kiosks that house the power receptacles, communications, and emergency alarm and lighting systems; and a central communications unit. This system makes sequential decommissioning efforts efficient and cost-effective by allowing the integrated system to remain intact while being moved to subsequent work sites. Use of the MITUS also eliminates the need to conduct zero-energy tests and implement associated lock-out/tag-out procedures at partially de-energized facilities. Since the MITUS is a designed system, it can be customized to accommodate unique facility conditions simply by varying kiosks and transformer configurations. The MITUS is an attractive alternate to the use of portable generators with stand-alone communications and emergency system. It is more cost-effective than upgrading or reconfiguring existing power distribution systems

    1987-01-01

    The International Symposium on Improvements in Water Reactor Fuel Technology and Utilization was organized by the International Atomic Energy Agency and held in Stockholm from 15 to 19 September 1986 at the invitation of the Government of Sweden. The aim was to give scientists and engineers working in these fields the opportunity to exchange information on their achievements to date and their future work. It was attended by about 170 participants from 29 Member States and one international organization. A total of 37 papers and 12 posters covering a wide range of topics related to water reactor fuel was presented. The number of participants as well as the large number of fuel vendors from Europe, Japan and the United States of America and some reactor utilities proved that the timing and the topic of the Symposium were well chosen. In general, the Symposium has shown that current water reactor fuels perform reliably and meet current performance requirements. The factors which could limit fuel performance under high burnup conditions and load follow mode of operation were discussed and defined. All 49 presentations were divided into 6 sections: introduction (3 general papers); fuel design and performance (15 papers); fuel materials and behavior (8 papers); structural materials (5 papers); fuel fabrication (6 papers) and poster section (12 papers). A separate abstract was prepared for each of these presentations

  19. Space Resource Utilization: Technologies and Potential Synergism with Terrestrial Mining

    2015-01-01

    Space Resources and Their Uses: The idea of using resources in space to support human exploration and settlement or for economic development and profit beyond the surface of Earth has been proposed and discussed for decades. Work on developing a method to extract oxygen from lunar regolith started even before humans set foot on the Moon for the first time. The use of space resources, commonly referred to as In Situ Resource Utilization (ISRU), involves the processes and operations to harness and utilize resources in space (both natural and discarded) to create products for subsequent use. Potential space resources include water, solar wind implanted volatiles (hydrogen, helium, carbon, nitrogen, etc.), vast quantities of metals and minerals in extraterrestrial soils, atmospheric constituents, unlimited solar energy, regions of permanent light and darkness, the vacuum and zero-gravity of space itself, trash and waste from human crew activities, and discarded hardware that has completed its primary purpose. ISRU covers a wide variety of concepts, technical disciplines, technologies, and processes. When considering all aspects of ISRU, there are 5 main areas that are relevant to human space exploration and the commercialization of space: 1. Resource Characterization and Mapping, 2. In Situ Consumables Production, 3. Civil Engineering and Construction, 4. In Situ Energy Production and Storage, and 5. In Situ Manufacturing.

    This study examined the association of housing status over time with unmet physical health care needs and emergency department utilization among homeless and vulnerably housed persons in Canada. Homeless and vulnerably housed individuals completed interviewer-administered surveys on housing, unmet physical health care needs, health care utilization, sociodemographic characteristics, substance use, and health conditions at baseline and annually for 4 years. Generalized logistic mixed effects regression models examined the association of residential stability with unmet physical health care needs and emergency department utilization, adjusting for potential confounders. Participants were from Vancouver (n = 387), Toronto (n = 390), and Ottawa (n = 396). Residential stability was associated with lower odds of having unmet physical health needs (adjusted odds ratio (AOR), 0.82; 95 % confidence interval (CI), 0.67, 0.98) and emergency department utilization (AOR, 0.74; 95 % CI, 0.62, 0.88) over the 4-year follow-up period, after adjusting for potential confounders. Residential stability is associated with fewer unmet physical health care needs and lower emergency department utilization among homeless and vulnerably housed individuals. These findings highlight the need to address access to stable housing as a significant determinant of health disparities.

    1998-01-01

    The Airlie House Pollution Prevention Technology Transfer Projects were a series of pilot projects developed for the US Department of Energy with the intention of transferring pollution prevention technology to the private sector. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education project, the microscale cost benefit study project, and the Bethel New Life recycling trainee project. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The Bethel New Life recycling trainee project provided training for two participants who helped identify recycling and source reduction opportunities in Argonne National Laboratory's solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identifying target technologies that were already available, identifying target audiences, and focusing on achieving a limited but defined objective

    The Annual Report presents the fiscal year (FY) 1988 research activities and accomplishments, for the Biocatalysis Project of the U.S. Department of Energy, Energy Conversion and Utilization Technologies (ECUT) Division. The ECUT Biocatalysis Project is managed by the Jet Propulsion Laboratory, California Institute of Technology. The Biocatalysis Project is a mission-oriented, applied research and exploratory development activity directed toward resolution of the major generic technical barriers that impede the development of biologically catalyzed commercial chemical production. The approach toward achieving project objectives involves an integrated participation of universities, industrial companies and government research laboratories. The Project's technical activities were organized into three work elements: (1) The Molecular Modeling and Applied Genetics work element includes research on modeling of biological systems, developing rigorous methods for the prediction of three-dimensional (tertiary) protein structure from the amino acid sequence (primary structure) for designing new biocatalysis, defining kinetic models of biocatalyst reactivity, and developing genetically engineered solutions to the generic technical barriers that preclude widespread application of biocatalysis. (2) The Bioprocess Engineering work element supports efforts in novel bioreactor concepts that are likely to lead to substantially higher levels of reactor productivity, product yields and lower separation energetics. Results of work within this work element will be used to establish the technical feasibility of critical bioprocess monitoring and control subsystems. (3) The Bioprocess Design and Assessment work element attempts to develop procedures (via user-friendly computer software) for assessing the energy-economics of biocatalyzed chemical production processes, and initiation of technology transfer for advanced bioprocesses.

  3. Utilizing information technologies for lifelong monitoring in diabetes patients.

    2011-01-01

    Information and communication technologies have long been acknowledged to support information sharing along the whole chain of care, from the clinic to the homes of patients and their relatives. Thus they are increasingly being considered for improving the delivery of health care services also in light of clinical and technological achievements that propose new treatments requiring a tighter interaction among patients and physicians. The multiagent paradigm has been utilized within an architecture for delivering telemedicine services to chronic outpatients at their domiciles and enforcing cooperation among patients, caregivers, and different members of the health care staff. The architecture sees each communication device such as a palmtop, smart phone, or personal digital assistant as a separate agent upon which different services are deployed, including telemetry, reminders, notifications, and alarms. Decoupling services from agents account for a highly configurable environment applicable to almost any context that can be customized as needed. The architecture has been used for designing and implementing a prototypical software infrastructure, called LifePhone, that runs on several communication devices. A basic set of services has been devised with which we were able to configure two different applications that address long-term and short-term monitoring scenarios for diabetes patients. The long-term scenario encompasses telemetry and reminder services for patients undergoing peritoneal dialysis, which is a treatment for chronic renal failure, a diabetes complication. The short-term scenario incorporates telemetry and remote alarms and is applicable for training patients to use an artificial pancreas. Our experiments proved that an infrastructure such as LifePhone can be used successfully for bridging the interaction gap that exists among all the components of a health care delivery process, improving the quality of service and possibly reducing the overall

    The purpose of the study was to explore whether or not the assistive and safety technology that is currently used in service house environment supports the active agency of the elderly residents. Twelve purposively chosen elderly residents were interviewed. The data were analyzed by theory-driven content analysis using the modalities of the agency-model as a theoretical frame. The technological devices and systems partially support the active agency of the residents. Deterioration of their functioning seems to limit the use of devices as well as complicate their learning on how to use these systems. The respondents had only few insights of the possibilities that this technology could offer to them in their daily life and they were not expecting their functioning to improve in the future. The homeliness and intimacy of the environment was highly appreciated. Although the attitude towards technology was, in general, reserved, technology was seen as one possibility to support active agency. The current technologies seem to be designed from the needs of the organization and not from the needs of the residents. In the future, more emphasis needs to be put on designing individualized devices in cooperation with the users. Implications for Rehabilitation To support independence, autonomy and active agency of the older adults, the technological solutions must be based on perceived needs of the individual and the design should be adaptable to the functional limitations one has. Nursing staff's knowledge about assistive devices and technologies need to be updated on regular bases in order to be able to recommend appropriate devices for the elderly. Taking into account the fact that many older adults have mild to moderate memory problems as well as difficulties with vision and hearing, more attention needs to be paid to didactics, i.e. how the introduction and guidance of the use of new technologies, assistive devices or safety systems is best done with them.

    Molecular techniques are an alternative to culturing and counting methods in quantifying indoor fungal contamination. Pyrosequencing offers the possibility of identifying unexpected indoor fungi. In this study, 50 house dust samples were collected from homes in the Yakima Valley, WA. Each sample was analyzed by quantitative PCR (QPCR) for 36 common fungi and by fungal tag-encoded flexible (FLX) amplicon pyrosequencing (fTEFAP) for these and additional fungi. Only 24 of the samples yielded amplified results using fTEFAP but QPCR successfully amplified all 50 samples. Over 450 fungal species were detected by fTEFAP but most were rare. Twenty-two fungi were found by fTEFAP to occur with at least an average of ≥0.5% relative occurrence. Many of these fungi seem to be associated with plants, soil or human skin. Combining fTEFAP and QPCR can enhance studies of fungal contamination in homes.

  6. Utilizing Solar Power Technologies for On-Orbit Propellant Production

    Fikes, John C.; Howell, Joe T.; Henley, Mark W.

    2006-01-01

    The cost of access to space beyond low Earth orbit may be reduced if vehicles can refuel in orbit. The cost of access to low Earth orbit may also be reduced by launching oxygen and hydrogen propellants in the form of water. To achieve this reduction in costs of access to low Earth orbit and beyond, a propellant depot is considered that electrolyzes water in orbit, then condenses and stores cryogenic oxygen and hydrogen. Power requirements for such a depot require Solar Power Satellite technologies. A propellant depot utilizing solar power technologies is discussed in this paper. The depot will be deployed in a 400 km circular equatorial orbit. It receives tanks of water launched into a lower orbit from Earth, converts the water to liquid hydrogen and oxygen, and stores up to 500 metric tons of cryogenic propellants. This requires a power system that is comparable to a large Solar Power Satellite capable of several 100 kW of energy. Power is supplied by a pair of solar arrays mounted perpendicular to the orbital plane, which rotates once per orbit to track the Sun. The majority of the power is used to run the electrolysis system. Thermal control is maintained by body-mounted radiators; these also provide some shielding against orbital debris. The propellant stored in the depot can support transportation from low Earth orbit to geostationary Earth orbit, the Moon, LaGrange points, Mars, etc. Emphasis is placed on the Water-Ice to Cryogen propellant production facility. A very high power system is required for cracking (electrolyzing) the water and condensing and refrigerating the resulting oxygen and hydrogen. For a propellant production rate of 500 metric tons (1,100,000 pounds) per year, an average electrical power supply of 100 s of kW is required. To make the most efficient use of space solar power, electrolysis is performed only during the portion of the orbit that the Depot is in sunlight, so roughly twice this power level is needed for operations in sunlight

    Indonesia has an advantage in producing exotic coffee that is Luwak coffee. Luwak coffee is produced from the fermentation process in digestion of civet. Luwak coffee production is still limited due to the difficulty level in the use of civet animals as the only medium of Luwak coffee making. The research was conducted by developing technology of luwak coffee production through bioreactor utilization and addition the bacteria isolate from gastric of civet. The process conditions in the bioreactor which include temperature, pH, and bacteria isolate of civet are adjusted to the process that occurs in civet digestion, including peristaltic movement on the stomach and small intestine of the civet will be replaced by the use of propellers that rotate on the bioreactor. The result of research showed that proximat analysis data of artificial/bioreactor luwak coffee did not significant different with original luwak coffee. However, the original luwak coffee has higher content of caffeine compared to bioreactor luwak coffee. Based on the cuping test the bioreactor luwak coffee has a value of 84.375, while the original luwak coffee is 84.875. As the result, bioreactor luwak coffee has excellent taste that similiar with original luwak coffee taste.

  11. Reduction of carbon dioxide emissions by solar water heating systems and passive technologies in social housing

    2015-01-01

    Growing global concern regarding climate change motivates technological studies to minimize environmental impacts. In this context, solar water heating (SWH) systems are notably prominent in Brazil, primarily because of the abundance of solar energy in the country. However, SWH designs have not always been perfectly developed. In most projects, the installation option of the solar system only considers the electric power economy aspects and not the particular characteristics of each climatic zone. Thus, the primary objective of this paper is to assess the potential of carbon dioxide reduction with the use of SWH in comparison with electric showers in social housing in several Brazilian climatic zones. The Brazilian government authorities have created public policies to encourage the use of these technologies primarily among the low-income population. The results of this paper indicate that hot climactic regions demonstrate a low reduction of CO 2 emissions with SWH installations. Thus, solar radiation is not useful for water heating in those regions, but it does lead to a large fraction of household cooling loads, implying a demand for electrical energy for air conditioning or requiring the adoption of passive techniques to maintain indoor temperatures below threshold values. -- Graphical abstract: Display Omitted -- Highlights: •Brazil has created public policies to increase the use of solar water heating in social housing. •We have evaluated the potential for reduction of CO 2 emissions installing solar water heating. •We have found that the coldest regions have the greatest potential for reducing emissions. •Passive technologies for thermal comfort in hot climate households are more useful than solar water heating systems

    Supportive housing, defined as subsidized housing in conjunction with site-based social services, may help improve the health and residential stability of highly disadvantaged individuals. This study examined changes in health status, quality of life, substance use, health care utilization, and residential stability among 112 homeless and vulnerably housed individuals who applied to a supportive housing program in Toronto, Canada, from December 2005 to June 2007. Follow-up interviews were conducted every 6 months for 18 months. Comparisons were made between individuals who were accepted into the program (intervention) and those who were wait-listed (usual care) using repeated-measures analyses. Individuals who were accepted into the housing program experienced significantly greater improvements in satisfaction with living situation compared with individuals in the usual care group (time, F(3,3,261) = 47.68, p homeless individuals was limited by the small number of participants who were literally homeless at baseline and by the large number of participants who gained stable housing during the study period regardless of their assigned housing status. Nonetheless, this study shows that highly disadvantaged individuals with a high prevalence of poor physical and mental health and substance use can achieve stable housing.

    Given the high demands on a multidisciplinary approach to sample collection, and despite the rigorous quality assurance and quality control measures designed to minimize sample misidentification in our state of the art biorepository, the potential for error is still a concern. Measures to deal with potential uncertainties are a necessary part of every successful biobanking operation. The Beaumont BioBank and associated Core Molecular Laboratory have developed procedures to address these rare incidents. Here we present a case study of occurrences in the Beaumont BioBank in which the identity of samples was uncertain and a resolution workflow was implemented to quickly remove the ambiguity. Using Core Molecular Laboratory in-house resources, including Mass Array technology and the valuable insight and experience from a multidisciplinary team, a comprehensive troubleshooting schema has been developed and applied toward resolving sample identification uncertainties. As per standard operating procedures, each step of these incidents was recorded and a final report prepared.

    The development and design of animal facilities are described in terms of the technological needs for NASA's Biological Flight Research Laboratory. Animal habitats are presented with illustrations which encompass waste-collection techniques for microgravity conditions that reduce the need for crew participation. The technology is intended to be highly compatible with animal morphology, and airflow is employed as the primary mechanism of waste control. The airflow can be utilized in the form of localized high-speed directed flow that simultaneously provides a clean animal habitat and low airflow rates. The design of an animal-habitat testbed is presented which capitalizes on contamination-control mechanisms and suitable materials for microgravity conditions. The developments in materials and technologies represent significant contributions for the design of the centrifuge facilities for the Space Station Freedom.

    Residence in public rental housing is an area-level measure of socioeconomic status, but its impact as a social determinant of health in Singapore has not been studied. We therefore aimed to examine the association of public rental housing with readmission risk and increased utilization of hospital services in Singapore. We conducted a retrospective cohort study using retrospective 2014 data from Singapore General Hospital's electronic health records. Variables known to affect readmission risk and health-care utilization were identified a priori and include patient demographics, comorbidities, health-care utilization in the preceding 1 year and clinical variables from the index admission in 2014. Multivariate logistic regression was used to evaluate public rental housing as an independent risk factor for admission risk, emergency department (ED), and specialist outpatient clinic attendances. A total of 14,457 unique patients were analyzed, and 2,163 patients (15.0%) were rental housing residents. Rental housing patients were significantly more likely to be male; required financial assistance; have chronic obstructive pulmonary disease; usage of anti-depressant and anti-psychotic medications; longer length of hospital stay during the index admission; and higher Charlson Comorbidity Index scores. After adjusting for demographics and clinical variables, staying in public rental housing remained an independent risk factor for readmission within 15 and 30 days, frequent hospital admissions and ED attendances in Singapore. Our study showed an association between public rental housing with readmission risk and increased utilization of hospital services in Singapore. A deeper understanding of the residents' social circumstances and health seeking behavior would be insightful.

Computer vision is one of the technologies that are most widely used in food industries and agriculture. In this paper, an automated system based on computer vision for harvesting greenhouse tomatoes is presented. A CCD camera takes images from workspace and tomatoes with over 50 percent ripeness are detected through an image processing algorithm. In this research three color spaces including RGB, HSI and YCbCr and three algorithms including threshold recognition, curvature of the image and red/green ratio were used in order to identify the ripe tomatoes from background under natural illumination. The average error of threshold recognition, red/green ratio and curvature of the image algorithms were 11.82%, 10.03% and 7.95% in HSI, RGB and YCbCr color spaces, respectively. Therefore, the YCbCr color space and curvature of the image algorithm were identified as the most suitable for recognizing fruits under natural illumination condition.

  2. Groundwater-risk analysis of New York utilizing GIS technology

    Hillenbrand, Charles John, III

    Using Geographic Information System (GIS) technology, data layers can be processed and analyzed to produce a regional groundwater-risk grid of New York State (NYS). GIS can be used to assess the potential to introduce contaminants at the ground surface, and assess the potential for the contaminants to migrate through the vadose zone and be introduced to an aquifer at the water-table. The potential to introduce contaminants to the ground surface was assessed utilizing existing database information in combination with the United States Geological Survey (USGS) Multi-Resolution Land Classification (MRLC) land use grid. The databases allowed an analysis of contaminant association with Standard Industrial Classification (SIC) codes, risk evaluation of the contaminants using groundwater intake values protective of human health, the development of SIC code-risk values, the construction of a SIC code-risked facility point coverage, and the construction of a land use-risk grid; this grid assesses the potential to introduce contaminants to the ground surface. Aquifer susceptibility was determined by analyzing vadose zone residence time assuming saturated conditions. Vadose zone residence time is a measure of the vadose zone's ability to attenuate and retard the migration of contaminants. Existing data layers were processed to produce a depth to water-table (vadose zone thickness) grid. Existing GIS data layers of soil, surficial geology and bedrock geology, along with review of literature and pump/slug test data, enabled the creation of thickness, porosity and vertical hydraulic conductivity grids for the three considered components of the vadose zone. The average linear velocity was then calculated for each vadose zone component by dividing their hydraulic conductivity grid by their respective porosity grid. The thickness grid of each vadose zone component was then divided by their respective average linear velocity grid to produce vadose zone residence time grids. The sum

    Incorporating new technology is a hallmark of space missions. Missions demand ever-improving tools and techniques to allow them to meet the mission science requirements. In Earth Science, these technologies are normally expressed in new instrument capabilities that can enable new measurement concepts, extended capabilities of existing measurement techniques, or totally new detection capabilities, and also, information systems technologies that can enhance data analysis or enable new data analyses to advance modeling and prediction capabilities. Incorporating new technologies has never been easy. There is a large development step beyond demonstration in a laboratory or on an airborne platform to the eventual space environment that is sometimes referred to as the "technology valley of death." Studies have shown that non-validated technology is a primary cause of NASA and DoD mission delays and cost overruns. With the demise of the New Millennium Program within NASA, opportunities for demonstrating technologies in space have been rare. Many technologies are suitable for a flight project after only ground testing. However, some require validation in a relevant or a space flight environment, which cannot be fully tested on the ground or in airborne systems. NASA's Earth Science Technology Program has initiated a nimble program to provide a fairly rapid turn-around of space validated technologies, and thereby reducing future mission risk in incorporating new technologies. The program, called In-Space Validation of Earth Science Technology (InVEST), now has five tasks in development. Each are 3U CubeSats and they are targeted for launch opportunities in the 2016 time period. Prior to formalizing an InVEST program, the technology program office was asked to demonstrate how the program would work and what sort of technologies could benefit from space validation. Three projects were developed and launched, and have demonstrated the technologies that they set out to validate

    1989-11-01

    The study examines the feasibility of incorporating the use of earth-coupled heat pump technology in single-family housing rehabilitation projects, based on energy conservation attributes and financial considerations. Following evaluation of a theoretical model which indicated that installations of the heat pumps were feasible, the heat pumps were tested under actual conditions in five single family housing units which were part of the Urban Homesteading Program, and were matched with comparable units which did not receive special treatment. Energy consumption information was collected for all units for twelve months. Variables were identified, and the data was analyzed for individual housing units and compared with the results predicted by the theoretical model to determine the practicality of incorporating such technology in large scale rehabilitation projects. 14 refs., 14 figs., 3 tabs.

    Full Text Available Attention to integrate technology in teaching and learning has provided a major transformation in the landscape of education. Therefore, many innovations in teaching and learning have been technology-driven. The study attempted to examine what is engineering students’ perception regarding the use of Information and Communication Technologies (ICT in mathematics learning as well as investigate their opinion about how ICT can be integrated to improve teaching and learning processes. The subjects were Iranian engineering students from two universities. The finding showed they are fully aware of importance of ICT in teaching and learning mathematics. Whilst, they were feeling comfortable and confident with technology, they do not have more experience of using technology in mathematics classes before. The findings supported the other studies, which indicated the potentials of ICT to facilitate students’ learning, improve teaching, and enhance institutional administration as established in the literature.Keywords: Technology, Mathematics Learning, Facebook, Attitude Toward ICT DOI: http://dx.doi.org/10.22342/jme.5.2.1498.138-147

    2007-05-25

    The Savannah River Site (SRS) Figure 1 is a 310-square-mile United States Department of Energy nuclear facility located along the Savannah River near Aiken, South Carolina. During operations, which started in 1951, hazardous substances (chemicals and radionuclides) were released to the environment. The releases occurred as a result of inadvertent spills and waste disposal in unlined pits and basins which was common practice before environmental regulations existed. The hazardous substances have migrated to the vadose zone and groundwater in many areas of the SRS, resulting in 515 waste units that are required by environmental regulations, to undergo characterization and, if needed, remediation. In the initial years of the SRS environmental cleanup program (early 1990s), the focus was to use common technologies (such as pump and treat, air stripping, excavation and removal) that actively and tangibly removed contamination. Exclusive use of these technologies required continued and significant funding while often failing to meet acceptable clean-up goals and objectives. Recognizing that a more cost-effective approach was needed, SRS implemented new and complementary remediation methods focused on active and passive technologies targeted to solve specific remediation problems. Today, SRS uses technologies such as chemical/pH-adjusting injection, phytoremediation, underground cutoff walls, dynamic underground stripping, soil fracturing, microbial degradation, baroballs, electrical resistance heating, soil vapor extraction, and microblowers to more effectively treat contamination at lower costs. Additionally, SRS's remediation approach cost effectively maximizes cleanup as SRS works proactively with multiple regulatory agencies. Using GIS, video, animation, and graphics, SRS is able to provide an accurate depiction of the evolution of SRS groundwater and vadose zone cleanup activities to convince stakeholders and regulators of the effectiveness of various cleanup

    1980-01-01

    Needs of the general aviation industry for services and facilities which might be supplied by NASA were examined. In the data collection phase, twenty-one individuals from nine manufacturing companies in general aviation were interviewed against a carefully prepared meeting format. General aviation avionics manufacturers were credited with a high degree of technology transfer from the forcing industries such as television, automotive, and computers and a demonstrated ability to apply advanced technology such as large scale integration and microprocessors to avionics functions in an innovative and cost effective manner. The industry's traditional resistance to any unnecessary regimentation or standardization was confirmed. Industry's self sufficiency in applying advanced technology to avionics product development was amply demonstrated. NASA research capability could be supportive in areas of basic mechanics of turbulence in weather and alternative means for its sensing.

    AUTHOR|(CDS)2088631; The ATLAS collaboration

    2017-01-01

    Because of their performance characteristics high-performance fabrics like Infiniband or OmniPath are interesting technologies for many local area network applications, including data acquisition systems for high-energy physics experiments like the ATLAS experiment at CERN. This paper analyzes existing APIs for high-performance fabrics and evaluates their suitability for data acquisition systems in terms of performance and domain applicability. The study finds that existing software APIs for high-performance interconnects are focused on applications in high-performance computing with specific workloads and are not compatible with the requirements of data acquisition systems. To evaluate the use of high-performance interconnects in data acquisition systems a custom library, NetIO, is presented and compared against existing technologies. NetIO has a message queue-like interface which matches the ATLAS use case better than traditional HPC APIs like MPI. The architecture of NetIO is based on a interchangeable bac...

    2001-06-01

    The following paper provides an overview of GE's H System{trademark} technology, and specifically, the design, development, and test activities associated with the DOE Advanced Turbine Systems (ATS) program. There was intensive effort expended in bringing this revolutionary advanced technology program to commercial reality. In addition to describing the magnitude of performance improvement possible through use of H System{trademark} technology, this paper discusses the technological milestones during the development of the first 9H (50Hz) and 7H (60 Hz) gas turbines. To illustrate the methodical product development strategy used by GE, this paper discusses several technologies that were essential to the introduction of the H System{trademark}. Also included are analyses of the series of comprehensive tests of materials, components and subsystems that necessarily preceded full scale field testing of the H System{trademark}. This paper validates one of the basic premises with which GE started the H System{trademark} development program: exhaustive and elaborate testing programs minimized risk at every step of this process, and increase the probability of success when the H System{trademark} is introduced into commercial service. In 1995, GE, the world leader in gas turbine technology for over half a century, in conjunction with the DOE National Energy Technology Laboratory's ATS program, introduced its new generation of gas turbines. This H System{trademark} technology is the first gas turbine ever to achieve the milestone of 60% fuel efficiency. Because fuel represents the largest individual expense of running a power plant, an efficiency increase of even a single percentage point can substantially reduce operating costs over the life of a typical gas-fired, combined-cycle plant in the 400 to 500 megawatt range. The H System{trademark} is not simply a state-of-the-art gas turbine. It is an advanced, integrated, combined-cycle system in which every

    2015-01-01

    RapidArc™ is a radiation technique that delivers highly conformal dose distributions through the complete rotation (360°) and speed variation of the linear accelerator gantry. This technique, called volumetric modulated arc therapy (VMAT), compared with conventional radiotherapy techniques, can achieve high-target volume coverage and sparing damage to normal tissues. RapidArc delivers precise dose distribution and conformity similar to or greater than intensity-modulated radiation therapy in a short time, generally a few minutes, to which image-guided radiation therapy is added. RapidArc has become a currently used technology in many centers, which use RapidArc technology to treat a large number of patients. Large and small hospitals use it to treat the most challenging cases, but more and more frequently for the most common cancers. The clinical use of RapidArc and VMAT technology is constantly growing. At present, a limited number of clinical data are published, mostly concerning planning and feasibility studies. Clinical outcome data are increasing for a few tumor sites, even if only a little. The purpose of this work is to discuss the current status of VMAT techniques in clinical use through a review of the published data of planning systems and clinical outcomes in several tumor sites. The study consisted of a systematic review based on analysis of manuscripts retrieved from the PubMed, BioMed Central, and Scopus databases by searching for the keywords “RapidArc”, “Volumetric modulated arc radiotherapy”, and “Intensity-modulated radiotherapy”

    In the course of the harmonization of the European legislation for the radiation protection the German radiation protection law must be adapted. RoeV and StrlSchV must be summarized to only one law. The education in the technical instruction can play here a pioneering role. In the course of this absolutely necessary new adjustment the law and directives texts must follow the technical progress and the developing state of the technology more unambiguously. Currently too many technical instruction groups are established in the radiation protection and partly wrong technical definitions are used. This leads partly to incorrect approval conditions using technical radiation sources. (orig.)

    Korea Hydro and Nuclear Power (KHNP) has been managed Nuclear Power Plant (NPP) construction projects including basic project planning, design, procurement, construction and start-up for nearly 30 years, and taken the leading role in the self-reliance program for constructing NPP. To maintain its leading position of construction technology and export it to other countries, it is more likely required to build the strong and competitive business management system to improve internal business efficiency and transparency, and also to respond to the change of external business circumstances such as electricity market opening. KHNP is implementing Enterprise Resource Planning (ERP) System as a business innovation tool to improve business efficiency, which changes the way of performing work from organizational system to process-oriented system in order to optimize the company resources to achieve above goals. This change should be made based on the results of performing Business Process Re-engineering (BPR) to maximize overall business efficiency. For the construction project management area, the establishment of Integrated Construction Information Sharing System based on Information Technology (IT) is the most important part. It makes possible to build collaboration system with 'Win-Win strategy' between the project owner and all related entities and to contribute to secure transparency and cut the project cost down. We would like to introduce our NPP Construction Project Management System, Infrastructure for Information System, Information Sharing System among construction related entities and Implementation Practices in this paper and also include the suggestions on our customary practice and subject that should be improved

    The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the U.S. Department of Energy (DOE) is the development of the GE 7H and 9H combined cycle power systems. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer conflation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. The objective of this task is to design 7H and 9H compressor rotor and stator structures with the goal of achieving high efficiency at lower cost and greater durability by applying proven GE Power Systems (GEPS) heavy-duty use design practices. The designs will be based on the GE Aircraft Engines (GEAE) CF6-80C2 compressor. Transient and steady-state thermo-mechanical stress analyses will be run to ensure compliance with GEPS life standards. Drawings will be prepared for forgings, castings, machining, and instrumentation for full speed, no load (FSNL) tests of the first unit on both 9H and 7H applications.

In the nuclear industry, check valve failures are known to have resulted in damaging water hammer conditions, overpressurization of low pressure systems, steam binding of auxiliary feedwater pumps, and other serious component damage in power plant environments. Similar problems exist in fossil power and various process industries, but the resources dedicated to valve maintenance issues are greatly reduced. However, the trend toward plant life extension, predictive maintenance, and maximum operating efficiency will raise the general awareness of check valve maintenance in commercial (non-nuclear) applications. Although this paper includes specific references to the nuclear industry, the check valve problem conditions and diagnostic techniques apply across all power and process plant environments. The ability to accurately diagnose check valve conditions using non-intrusive, predictive maintenance testing methods allows for a more cost-efficient, productive maintenance program. One particular diagnostic system, called Quickcheck trademark, assists utilities in addressing these concerns. This article presents actual field test data and analysis that demonstrate the power of check valve diagnostics. Prior to presenting the field data, a brief overview of the system is overviewed

    Full Text Available The affordances of mobile technologies are being felt in many sectors of world’s economy including university education. By solving the limitations of fixed instructional technologies, mobile technologies have received ready acceptance in the education place. The purpose of the study was to investigate the student technological preferences, their levels of utilization as well as attitudes toward mobile technologies. The target population was 30,752 third year undergraduate students in Kenyan Universities. The participants (n = 375 were selected by systematic random sampling. They provided data using self-fill questionnaires. Results indicated that the smartphone was the most popular mobile device; Tecno was the most preferred handset brand; and Android was the most popular operating system. Safaricom was the dominant service provider amongst the student population. Regarding the levels of utilization of mobile technologies by students, it was concluded that though students use their mobile devices sufficiently, the use of the devices for accessing teaching and learning content was considerably low. On the attitude of students towards mobile technologies, it was observed that a sizeable number of students preferred to use the technologies over other existing instructional technologies. The findings of this study will be useful to instructional technologists, education policy makers, mobile handset manufacturers, mobile service providers and university managers as they partner to roll out digital learning infrastructure for Kenyan tertiary education.

    This survey measured radiofrequency (RF) fields from wireless local area networks (WLANs) using Wi-Fi technology against a background of RF fields in the environment over the frequency range 75 MHz-3 GHz. A total of 356 measurements were conducted at 55 sites (including private residences, commercial spaces, health care and educational institutions, and other public spaces) in four countries (U.S., France, Germany, Sweden). Measurements were conducted under conditions that would result in the higher end of exposures from such systems. Where possible, measurements were conducted in public spaces as close as practical to the Wi-Fi access points. Additional measurements were conducted at a distance of approximately 1 m from a laptop while it was uploading and downloading large files to the WLAN. This distance was chosen to allow a useful comparison of fields in the far-field of the antenna in the laptop, and give a representative measure of the exposure that a bystander might receive from the laptop. The exposure to the user, particularly if the antenna of the client card were placed against his or her body, would require different measurement techniques beyond the scope of this study. In all cases, the measured Wi-Fi signal levels were very far below international exposure limits (IEEE C95.1-2005 and ICNIRP) and in nearly all cases far below other RF signals in the same environments. An discusses technical aspects of the IEEE 802.11 standard on which WLANs operate that are relevant to determining the levels of RF energy exposure from WLANs. Important limiting factors are the low operating power of client cards and access points, and the low duty cycle of transmission that normally characterizes their operation.

    Urban safety-net clinics are considered prime targets for the adoption of health information technology innovations; however, little is known about their utilization in such safety-net settings. Current scholarship provides limited guidance on the implementation of health information technology into safety-net settings as it typically assumes that adopting institutions have sufficient basic resources. This study addresses this gap by exploring the unique challenges urban resource-poor safety-net clinics must consider when adopting and utilizing health information technology. In-depth interviews (N = 15) were used with key stakeholders (clinic chief executive officers, medical directors, nursing directors, chief financial officers, and information technology directors) from staff at four clinics to explore (a) nonhealth information technology-related clinic needs, (b) how health information technology may provide solutions, and (c) perceptions of and experiences with health information technology. Participants identified several challenges, some of which appear amenable to health information technology solutions. Also identified were requirements for effective utilization of health information technology including physical infrastructural improvements, funding for equipment/training, creation of user groups to share health information technology knowledge/experiences, and specially tailored electronic billing guidelines. We found that despite the potential benefit that can be derived from health information technologies, the unplanned and uninformed introduction of these tools into these settings might actually create more problems than are solved. From these data, we were able to identify a set of factors that should be considered when integrating health information technology into the existing workflows of low-resourced urban safety-net clinics in order to maximize their utilization and enhance the quality of health care in such settings.

    Full Text Available Technology transfer has been a very frequent activity in the industrial world nowadays. Technology valuation, and in particular technology pricing, has played a considerable role in these transactions, in spite of a huge amount of limitations in the pricing methodologies applied. Making a sound, traceable and reliable means for applying the price evaluation procedure, seems as a technological requirement to be traced for. The objective of delivering this paper is to introduce a new numerical technology pricing method to provide the two transacting parties a unique compromised price. A three-dimensional model for technology pricing is proposed and The TOPSPS algorithm has been utilized to select the most similar technologies to the intended one and the constructed scoring system is applied to calculate the final technology price accordingly.

    Innovative technologies, built by either utility or nonutility power generators, have the potential to lower costs with less environmental emissions than conventional technologies. However, the public-good nature of information, along with uncertain costs, performance, and reliability, discourages rapid adoption of these technologies. The effect of regulation of electricity production may also have an adverse impact on motivation to innovate. Slower penetration of cleaner, more efficient technologies could result in greater levels of pollution, higher electricity prices, and a reduction in international competitiveness. Regulatory incentives could encourage adoption and deployment of innovative technologies of all kinds, inducting clean coal technologies. Such incentives must be designed to offset risks inherent in innovative technology and encourage cost-effective behavior. To evaluate innovative and conventional technologies equally, the incremental cost of risk (ICR) of adopting the innovative technology must be determined. Through the ICR, the magnitude of incentive required to make a utility (or nonutility) power generator equally motivated to use either conventional or innovative technologies can be derived. Two technology risks are examined: A construction risk, represented by a 15% cost overrun, and an operating risk, represented by a increased forced outage rate (decreased capacity factor). Different incentive mechanisms and measurement criteria are used to assess the effects of these risks on ratepayers and shareholders. In most cases, a regulatory incentive could offset the perceived risks while encouraging cost-effective behavior by both utility and nonutility power generators. Not only would the required incentive be recouped, but the revenue requirements would be less for the innovative technology; also, less environmental pollution would be generated. In the long term, ratepayers and society would benefit from innovative technologies.

    Full Text Available Abstract Background British government policy for older people focuses on a vision of active ageing and independent living. In the face of diminishing personal capacities, the use of appropriate home-based technology (HBT devices could potentially meet a wide range of needs and consequently improve many aspects of older people's quality of life such as physical health, psychosocial well-being, social relationships, and their physical or living environment. This study aimed to examine the use of HBT devices and the correlation between use of such devices and quality of life among older people living in extra-care housing (ECH. Methods A structured questionnaire was administered for this study. Using purposive sampling 160 older people living in extra-care housing schemes were selected from 23 schemes in England. A face-to-face interview was conducted in each participant's living unit. In order to measure quality of life, the SEIQoL-Adapted and CASP-19 were used. Results Although most basic appliances and emergency call systems were used in the living units, communally provided facilities such as personal computers, washing machines, and assisted bathing equipment in the schemes were not well utilised. Multiple regression analysis adjusted for confounders including age, sex, marital status, living arrangement and mobility use indicated a coefficient of 1.17 with 95% CI (0.05, 2.29 and p = 0.04 [SEIQoL-Adapted] and 2.83 with 95% CI (1.17, 4.50 and p = 0.001 [CASP-19]. Conclusions The findings of the present study will be value to those who are developing new form of specialised housing for older people with functional limitations and, in particular, guiding investments in technological aids. The results of the present study also indicate that the home is an essential site for developing residential technologies.

    Spanos, Ioannis; Duckers, Les; Holmes, Kenneth L.

    2007-01-01

    Current energy trends in UK housing are reviewed and then assessed by introducing the 'CARB financial analysis' methodology. CARB is an acronym for 'Carbon Abatement', as it evaluates the potential carbon-dioxide reduction from different technologies; 'Relative', as all the technologies examined are dependant on various primary sources; and 'Balance', as the cost of surplus CO 2 is quantified. According to conventional financial analysis, most of the technologies examined have the potential to provide positive returns on the investments especially for those with an environmentally conscious agenda. Further reduction of up to 30% of most installed alternative energy systems cost is required to compete with an investment in, e.g., a UK pension scheme. Using the 'CARB financial analysis' the cost of reducing CO 2 has been quantified, and compared with the potential cost of climate change impact. Conventional installed solar technologies are not financially attractive both with a pay back period calculations and 'CARB financial analysis' under current market costs and governmental subsidy regimes. Heat recovery technologies could be sensible investments, both in financial and environmental terms under particular assumptions; especially if the investment budget is small. The use of cogeneration technologies provides a financial advantage in the attempt to minimise the cost of climate change impact, as pay back period of such investment could be less than 7 yr, and the cost of CO 2 saved could be two to seven times less than the global damage cost of carbon emissions.

    2010-05-01

    We study the relationship between physician-hospital integration and its relation to monitoring IT utilization. We develop a theoretical model in which monitoring IT may complement or substitute for integration and test these relationships using a novel data source. Physician labor market heterogeneity identifies the empirical model. We find that monitoring IT utilization is increasing in integration, implying that expanded firm boundaries complement monitoring IT adoption. We argue that the relationship between monitoring IT and firm boundaries depends upon the contractibility of the monitored information.

    Hospitals with high-technology services may have better outcomes. However, access to high-technology hospitals might not be uniform across racial/ethnic groups. This study examined if racial/ethnic minorities, compared to whites, are less likely to utilize hospitals that have the availability of technology services and infrastructure items such as computed tomography, positron emission tomography, magnetic resonance imaging, diagnostics radiation facility, and a level 1 trauma unit. Data were obtained from the 2003 Healthcare Cost & Utilization Project's Nationwide Inpatient Sample and the 2003 American Hospital Association's annual survey data. The sample consisted of 3381 324 patients admitted to and discharged from 368 hospitals in 18 states in the United States. Logistic regression results suggest that Hispanic patients are less likely than whites to utilize high-technology hospitals when controlling for other factors (odds ratio[OR], 0.47; 95% confidence interval [CI], 0.28-0.79). Our study adds empirical evidence that significant gaps persist in access to care between minorities and whites. Particularly, access to high-technology hospitals for Hispanics appears to be a major problem.

Meanwhile, hand laterality in chimpanzees is weaker and controversial. Here we have reevaluated our results on hand laterality in chimpanzees housed in naturalistic environments at Fundació Mona (Spain) and Chimfunshi Wild Orphanage (Zambia). Our results show that the difference between hand laterality in humans and chimpanzees is not as great as once thought. Furthermore, we found a link between hand laterality and task complexity and also an even more interesting connection: CRD tasks elicited not only the hand laterality but also the use of tools. This paper aims to turn attention to the importance of this threefold connection in human evolution: the link between CRD tasks, hand laterality, and tool use, which has important evolutionary implications that may explain the development of complex behaviour in early hominins.

    2012-04-01

    Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels. A critical recent development, resulting from the massive scale of projects in progress or recently completed, is having the power sold directly to electric utilities. Such 'utility-scale' systems offer the opportunity to deploy solar technologies far faster than the traditional 'behind-the-meter' projects designed to offset retail load. Moreover, these systems have employed significant economies of scale during construction and operation, attracting financial capital, which in turn can reduce the delivered cost of power. This report is a summary of the current U.S. utility-scale solar state-of-the-market and development pipeline. Utility-scale solar energy systems are generally categorized as one of two basic designs: concentrating solar power (CSP) and photovoltaic (PV). CSP systems can be further delineated into four commercially available technologies: parabolic trough, central receiver (CR), parabolic dish, and linear Fresnel reflector. CSP systems can also be categorized as hybrid, which combine a solar-based system (generally parabolic trough, CR, or linear Fresnel) and a fossil fuel energy system to produce electric power or steam.

    Full Text Available The study focused on the extent of utilization of the educational innovations and technology in research and extension functions of SUs. The descriptive design, triangulation method, and purposive sampling were applied in this study. The findings revealed that majority of the respondents are married adults and master’s degree graduates with education as their area of specialization. They are permanent in status and have considerable years in the University serving as research or extension officer. Research of SUs have common research thrusts in terms of environment and natural resources management but differ in their own respective agenda; similarly the SUs share common extension thrusts and concerns but differ in their programs, activities and projects related to community services. Commonly encountered problems concern inadequate funds and inability to access the available technology. Officers utilized educational innovations on research and extension to a moderate extent but software and hardware were utilized to a great extent; likewise internet-based communication was utilized to a great extent for research but used moderately for extension. This implies that compared to research, most of the extension functions do not require the use of internet-based communication. From the results of the study, it was recommended that review of the existing allocation of funds for technology development may be done to improve the existing hardware, software and communication facilities.

    In this paper we propose a model to explain the behaviour of the Spanish electrical utility industry during the period 1987-1997, under the then existing regulatory system (Marco Legal Estable). The paper will study the presence of economies of scale, the effect of technological progress and the differences in the efficiency of the different companies within the market. The paper concludes that the Spanish electrical utility industry was not, in fact, characterized by economies of scale during this period, but witnessed a great improvement in efficiency within that period.

    Full Text Available Abstract Background Weaning of beef calves is a necessary husbandry practice and involves separating the calf from its mother, resulting in numerous stressful events including dietary change, social reorganisation and the cessation of the maternal-offspring bond and is often accompanied by housing. While much recent research has focused on the physiological response of the bovine immune system to stress in recent years, little is known about the molecular mechanisms modulating the immune response. Therefore, the objective of this study was to provide new insights into the molecular mechanisms underlying the physiological response to weaning at housing in beef calves using Illumina RNA-seq. Results The leukocyte transcriptome was significantly altered for at least 7 days following either housing or weaning at housing. Analysis of differentially expressed genes revealed that four main pathways, cytokine signalling, transmembrane transport, haemostasis and G-protein-coupled receptor (GPRC signalling were differentially regulated between control and weaned calves and underwent significant transcriptomic alterations in response to weaning stress on day 1, 2 and 7. Of particular note, chemokines, cytokines and integrins were consistently found to be up-regulated on each day following weaning. Evidence for alternative splicing of genes was also detected, indicating a number of genes involved in the innate and adaptive immune response may be alternatively transcribed, including those responsible for toll receptor cascades and T cell receptor signalling. Conclusions This study represents the first application of RNA-Seq technology for genomic studies in bovine leukocytes in response to weaning stress. Weaning stress induces the activation of a number of cytokine, chemokine and integrin transcripts and may alter the immune system whereby the ability of a number of cells of the innate and adaptive immune system to locate and destroy pathogens is

    Described in this paper is an air duct heat collecting system, forming a link in the chain of natural energy utilization, in an attic of a house actually in presence. When a sirocco fan (blowing air from an indoor induction duct into the room) at the base of the highblocked floor is turned, air is sucked through an air intake under the eaves into a heat collecting duct (constructed utilizing the tilt roof and rafter). Heat from the roof warmed by sunshine is absorbed by air in the heat collecting duct and is fed to the highblocked floor structure through a heat collecting room and the induction duct. This system functions quite effectively as a ventilating device. Dew condensation on the walls and floor and musty smell have been eliminated. This system is good enough as a heater even on chilly days in early spring when there is sunshine. In the time zone with the sun shining, the system collects 4{times}10{sup 4}kJ per day, exhibiting a heat collecting efficiency of 4%. The heat collecting duct was analyzed for thermal environment, and the heat flux of the collected heat was determined as Qk(W/m{sup 2}=0.1{times}I-1.3{Theta}d-{Theta}a). In this equation, I is the quantity of insolation (W/m{sup 2}), {Theta}d is the temperature in the heat collecting duct, and {Theta}a is the free air temperature. 2 refs., 8 figs.

  7. Retrofitting Housing with Lightweight Green Roof Technology in Sydney, Australia, and Rio de Janeiro, Brazil

    Full Text Available The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban heat island effect, increased bio-diversity, housing temperature attenuation and reduced stormwater run-off. The economic benefits are the reduced maintenance costs and lower running costs. The social gain is the creation of spaces where people have access to green areas. However, the barriers to retrofitting include the perceptions of structural adequacy, the risk of water damage, high installation and maintenance costs, as well as access and security issues. Many Australian and Brazilian residential buildings have metal sheet roofs, a lightweight material with poor thermal performance. During the summer, temperatures in Sydney and Rio de Janeiro reach 45 degrees Celsius, and in both cities, rainfall patterns are changing, with more intense downpours. Furthermore, many residential buildings are leased, and currently, tenants are restricted by the modifications that they can perform to reduce running costs and carbon emissions. This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that considerable variation in temperature was found in both countries, indicating that green roof retrofitting could lower the cooling energy demand considerably.

    Estimating potential of CO 2 emission reduction of non-capture CO 2 utilization (NCCU) technology was evaluated. NCCU is sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue gas. For the estimating the CO 2 emission reduction, process simulation using process simulator (PRO/II) based on a chemical plant which could handle CO 2 of 100 tons per day was performed, Also for the estimation of the indirect CO 2 reduction, the solvay process which is a conventional technology for the production of sodium carbonate/sodium bicarbonate, was studied. The results of the analysis showed that in case of the solvay process, overall CO 2 emission was estimated as 48,862 ton per year based on the energy consumption for the production of NaHCO 3 (7.4 GJ/tNaHCO 3 ). While for the NCCU technology, the direct CO 2 reduction through the CO 2 carbonation was estimated as 36,500 ton per year and the indirect CO 2 reduction through the lower energy consumption was 46,885 ton per year which lead to 83,385 ton per year in total. From these results, it could be concluded that sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue was energy efficient and could be one of the promising technology for the low CO 2 emission technology.

    To evaluate the opinions of practicing clinicians on medical television dramas and the effects these series have on society as well as their own practice. Observational study using a structured questionnaire disseminated among doctors of all grades and specialties at one tertiary centre and two large secondary care district general hospitals in Wales, United Kingdom. Three hundred and seventy-two questionnaires were distributed over a 3-month period, with 200 completed questionnaires received (response rate, 54%). Frequency and reasons for watching these programs, and opinions regarding realism, educational value and public perception, evaluated by doctors' grades and specialties. Identification of work practice with any observed traits in fictional doctors was also analysed. 65% of doctors surveyed admitted to watching these programs on more than one occasion. Junior doctors (interns and resident medical officers) were more regular viewers. Most doctors who admitted to watching medical dramas did so for entertainment purposes (69%); 8% watched for educational purposes and, of these, 100% watched House MD, 82% felt that these dramas were unrepresentative of daily practice, and 10% thought that they accurately portrayed reality. Most of the positive responses were from junior doctors. 61% of doctors identified some aspect of their clinical practice with another doctor (fictional or non-fictional; most junior doctors identified with a fictional doctor, compared with non-fictional role models for more senior practicing clinicians. This survey shows that a large body of the medical workforce watches medical television dramas and that such programs exercise a growing influence on the practice of junior doctors, particularly those in physicianly specialties. The reasons for certain role model selections remain unknown and may require further evaluation.

    2017-10-01

    The aim of this paper is the theoretical analysis of the possibilities and limitations of using an unconventional technology and the original architectural form stemming from it - the building with external construction and internal insulation. In Central European climatic conditions, the traditional solution for the walls of heated buildings relies on using external thermal insulation. This stems from building physics: it prevents interstitial condensation of water vapour in the wall. Internal insulation is used exceptionally. This is done e.g. in historical buildings undergoing thermal modernization (due to the impossibility of interfering with facade). In such cases, a thermal insulation layer is used on the internal wall surface, along with an additional layer of vapour barrier. The concept of building concerns the intentional usage of an internal insulation. In this case, the construction is a tight external reinforced concrete shell. The architectural form of such building is strongly interrelated with the technology, which was used to build it. The paper presents the essence of this concept in descriptive and drawing form. The basic elements of such building are described (the external construction, the internal insulation and ventilation). As a case study, authors present a project of a residential building along with the description of the applied materials and installation solutions, and the results obtained from thermal, humidity and energetic calculations. The discussion presents the advantages and disadvantages of the proposed concept. The basic advantage of this solution is potentially low building cost. This stems from minimizing the ground works, the simplicity of the joints and the outer finish, as well as from the possibility of prefabrication of the elements. The continuity of the thermal insulation allows to reduce the amount of thermal bridges. The applied technology and form are applicable most of all for small buildings, due to limited

    Incorporation of In-Situ Resource Utilization (ISRU) and the production of mission critical consumables for 9 propulsion, power, and life support into mission architectures can greatly reduce the mass, cost, and risk of missions 10 leading to a sustainable and affordable approach to human exploration beyond Earth. ISRU and its products can 11 also greatly affect how other exploration systems are developed, including determining which technologies are 12 important or enabling. While the concept of lunar ISRU has existed for over 40 years, the technologies and systems 13 had not progressed much past simple laboratory proof-of-concept tests. With the release of the Vision for Space 14 Exploration in 2004 with the goal of harnessing the Moon.s resources, NASA initiated the ISRU Project in the 15 Exploration Technology Development Program (ETDP) to develop the technologies and systems needed to meet 16 this goal. In the five years of work in the ISRU Project, significant advancements and accomplishments occurred in 17 several important areas of lunar ISRU. Also, two analog field tests held in Hawaii in 2008 and 2010 demonstrated 18 all the steps in ISRU capabilities required along with the integration of ISRU products and hardware with 19 propulsion, power, and cryogenic storage systems. This paper will review the scope of the ISRU Project in the 20 ETDP, ISRU incorporation and development strategies utilized by the ISRU Project, and ISRU development and 21 test accomplishments over the five years of funded project activity.

    Kloosterman, Jeff

    2012-12-31

    Air Products has developed a potentially ground-breaking technology – Sour Pressure Swing Adsorption (PSA) – to replace the solvent-based acid gas removal (AGR) systems currently employed to separate sulfur containing species, along with CO{sub 2} and other impurities, from gasifier syngas streams. The Sour PSA technology is based on adsorption processes that utilize pressure swing or temperature swing regeneration methods. Sour PSA technology has already been shown with higher rank coals to provide a significant reduction in the cost of CO{sub 2} capture for power generation, which should translate to a reduction in cost of electricity (COE), compared to baseline CO{sub 2} capture plant design. The objective of this project is to test the performance and capability of the adsorbents in handling tar and other impurities using a gaseous mixture generated from the gasification of lower rank, lignite coal. The results of this testing are used to generate a high-level pilot process design, and to prepare a techno-economic assessment evaluating the applicability of the technology to plants utilizing these coals.

    Technology-based applications represent a promising method for providing efficacious, widely available interventions to substance abuse treatment patients. However, limited access to communication technology (i.e., mobile phones, computers, internet, and e-mail) could significantly impact the feasibility of these efforts, and little is known regarding technology utilization in substance abusing populations. A survey was conducted to characterize utilization of communication technology in 266 urban, substance abuse treatment patients enrolled at eight drug-free, psychosocial or opioid-replacement therapy clinics. Survey participants averaged 41 years of age and 57% had a yearly household income of less than $15,000. The vast majority reported access to a mobile phone (91%), and to SMS text messaging (79%). Keeping a consistent mobile phone number and yearly mobile contract was higher for White participants, and also for those with higher education, and enrolled in drug-free, psychosocial treatment. Internet, e-mail, and computer use was much lower (39-45%), with younger age, higher education and income predicting greater use. No such differences existed for the use of mobile phones however. Concern regarding the digital divide for marginalized populations appears to be disappearing with respect to mobile phones, but still exists for computer, internet, and e-mail access and use. Results suggest that mobile phone and texting applications may be feasibly applied for use in program-client interactions in substance abuse treatment. Careful consideration should be given to frequent phone number changes, access to technology, and motivation to engage with communication technology for treatment purposes.

    E-health tools have the potential to improve the quality of care for ophthalmic patients, many of whom have chronic conditions. However, little research has assessed ophthalmic patients' use or acceptance of technological devices and social media platforms for health-related purposes. The present study evaluated utilization of technological devices and social media platforms by eye clinic patients, as well as their willingness to receive health reminders through these technologies. A 31-item paper questionnaire was administered to eye clinic patients (n=843) at an urban, tertiary-care center. Questions focused on technology ownership, comfort levels, frequency of use, and preferences for receiving health reminders. Demographic data were also recorded. Eye clinic patients most commonly owned cellular phones (90%), landline phones (81%), and computers (80%). Overall, eye clinic patients preferred to receive health reminders through phone calls and e-mail and used these technologies frequently and with a high level of comfort. Less than 3% of patients preferred using social networking to receive health reminders. In addition, age was significantly associated with technology ownership, comfort level, and frequency of use (p<0.05). The majority of patients 18-45 years of age preferred to receive appointment reminders via text message (57%) and e-mail (53%). This age group also used these technologies more frequently and with a higher comfort level (p<0.001). These data support the proposal that e-mail and text-messaging e-health tools are likely to be immediately adopted by eye clinic patients and therefore have the greatest potential to improve health outcomes and increase quality of care. Eye clinic patients are interested in these technologies for appointment reminders, general eye and vision health information, asking urgent medical questions, and requesting prescription refills. Future controlled trials could further explore the efficacy of e-health tools for these

    2005-11-01

    The characterization, porosity, permeability and integrity of conductive and non-conductive medical and consumer flexible barrier packaging material are determined utilizing a novel electron beam technology and electronic instrumentation in an open atmosphere for 100% real-time, on-line testing. The electron beam developed in an open atmosphere maintains its prescribed frequency through the use of a nitrogen cover gas, ionizing the gas to create a corona beam. The corona beam discharge, maintained at a high negative voltage, forms from the holes or anomalies in the flexible barrier material. The anomaly is detected and analyzed in order to determine the presence of viral and sub-viral sized voids or holes, as well as other anomalies such as blisters and bubbles. The process can also utilize an established range of acceptability to certify materials that require a well defined level of permeability. This process can be performed by the flexible barrier film manufacturer to certify a specific quality level. It can be performed by the material fabricator to ensure quality standards for preformed materials. It can also be performed by the product packaging manufacturer that uses the packaging material to wrap their products and confirm the integrity of the final sealed package by measuring the atmosphere inside the finished package. There are many other packaging applications that can utilize this technology for film characterization, validation and integrity testing within the pharmaceutical, medical device, and food processing industries, as well as other industrial applications.

    2009-03-29

    The EERC developed an applied research consortium project to test cost-effective mercury (Hg) control technologies for utilities burning bituminous coals. The project goal was to test innovative Hg control technologies that have the potential to reduce Hg emissions from bituminous coal-fired power plants by {ge}90% at costs of one-half to three-quarters of current estimates for activated carbon injection (ACI). Hg control technology evaluations were performed using the EERC's combustion test facility (CTF). The CTF was fired on pulverized bituminous coals at 550,000 Btu/hr (580 MJ/hr). The CTF was configured with the following air pollution control devices (APCDs): selective catalytic reduction (SCR) unit, electrostatic precipitator (ESP), and wet flue gas desulfurization system (WFDS). The Hg control technologies investigated as part of this project included ACI (three Norit Americas, Inc., and eleven Envergex sorbents), elemental mercury (Hg{sup 0}) oxidation catalysts (i.e., the noble metals in Hitachi Zosen, Cormetech, and Hitachi SCR catalysts), sorbent enhancement additives (SEAs) (a proprietary EERC additive, trona, and limestone), and blending with a Powder River Basin (PRB) subbituminous coal. These Hg control technologies were evaluated separately, and many were also tested in combination.

    2011-01-01

    Full Text Available Transfer of technologies produced by research is critical to innovation within all organizations. The intent of this paper is to take stock of the conceptual underpinnings of technology transfer processes as they relate to wood utilization research and to identify conditions that promote the successful transfer of research results. Conceptually, research utilization can be viewed from multiple perspectives, including the haphazard diffusion of knowledge in response to vague and imprecise demands for information, scanning of multiple information sources by individuals and organizations searching for useful scientific knowledge, engagement of third parties to organize research results and communicate them to potential users, and ongoing and active collaboration between researchers and potential users of research. Empirical evidence suggests that various types of programs can promote technology transfer (venture capital, angel investors, business incubators, extension services, tax incentives, and in-house entities, the fundamental effectiveness of which depends on research results that are scientifically valid and consistent with the information needs of potential users. Furthermore, evidence suggests preference toward programs that are appropriately organized and governed, suitably led and creatively administered, and periodically evaluated in accordance with clear standards of success.

    A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

    All artificial systems and components in space degrade at higher rates than on Earth, depending in part on environmental conditions, design approach, assembly technologies, and the materials used. This degradation involves not only the hardware and software systems but the humans that interact with those systems. All technological functions and systems can be expressed through functional dependence: [Function]˜[ERU]∗[RUIS]∗[ISR]/[DR];where [ERU]efficiency (rate) of environmental resource utilization[RUIS]resource utilization infrastructure[ISR]in situ resources[DR]degradation rateThe limited resources of spaceflight and open space for autonomous missions require a high reliability (maximum possible, approaching 100%) for system functioning and operation, and must minimize the rate of any system degradation. To date, only a continuous human presence with a system in the spaceflight environment can absolutely mitigate those degradations. This mitigation is based on environmental amelioration for both the technology systems, as repair of data and spare parts, and the humans, as exercise and psychological support. Such maintenance now requires huge infrastructures, including research and development complexes and management agencies, which currently cannot move beyond the Earth. When considering what is required to move manned spaceflight from near Earth stations to remote locations such as Mars, what are the minimal technologies and infrastructures necessary for autonomous restoration of a degrading system in space? In all of the known system factors of a mission to Mars that reduce the mass load, increase the reliability, and reduce the mission’s overall risk, the current common denominator is the use of undeveloped or untested technologies. None of the technologies required to significantly reduce the risk for critical systems are currently available at acceptable readiness levels. Long term interplanetary missions require that space programs produce a craft

    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

    This report documents both the process and the output of the process of establishing a peer review panel primarily from the private sector to suggest research and development activities appropriate for government sponsorship through the US Department of Energy (DOE) Energy Conversion and Utilization Technologies (ECUT) Program on the subject of thermal insulation. We expect to use information and guidance from the document during the federal budgetary process to allow more informed decision making. All related results of that budgetary decision making will affect what the DOE or Oak Ridge National Laboratory (ORNL) can and will sponsor during this or subsequent years through detailed decisions of DOE and ORNL program managers.

    Disparities in infertility and access to infertility treatments, such as assisted reproductive technology (ART), by race/ethnicity, have been reported. However, identifying disparities in ART usage may have been hampered by missing race/ethnicity information in ART surveillance. We review infertility prevalence and treatment disparities, use recent data to examine ART use in the United States by race/ethnicity and residency in states with mandated insurance coverage for in vitro fertilization (IVF), and discuss approaches for reducing disparities. We used 2014 National ART Surveillance System (NASS) data to calculate rates of ART procedures per million women 15-44 years of age, a proxy measure of ART utilization, for Census-defined racial/ethnic groups in the United States; rates were further stratified by the presence of insurance mandates for IVF treatment. Missing race/ethnicity data (35.6% of cycles) were imputed. Asian/Pacific Islander (A/PI) women had the highest rates of ART utilization at 5883 ART procedures per million women 15-44 years of age in 2014, whereas American Indian/Alaska Native non-Hispanic women had the lowest rates at 807 per million, compared with other racial/ethnic groups. In each racial/ethnic category, ART utilization rates were higher for women in states with an insurance mandate for IVF treatment versus those without. In 2014, A/PI women had the highest rates of ART utilization. ART utilization for all racial/ethnic groups was higher in states with insurance mandates for IVF than those without, although disparities were still evident. Although mandates may increase access to infertility treatments, they are not sufficient to eliminate these disparities.

    Recommendations and guidelines for the collection, generation, source and usage of utility data for health technology assessment (HTA) vary across different countries, with no international consensus. Many international agencies generate their own guidelines providing details on their preferred methods for HTA submissions, and there is variability in both what they recommend and the clarity and amount of detail provided in their guidelines. This article provides an overview of international regulations and recommendations for utility data in HTA for a selection of key HTA countries: Australia, Canada, France, Germany, the Netherlands, Spain (Catalonia), Sweden and the UK (England/Wales and Scotland). International guidelines are typically clear and detailed for the selection of countries assessed regarding the source description of health states (e.g. generic preference-based measure) and who should provide preference weights for these health states (e.g. general population for own country). Many guidelines specify the use of off-the-shelf generic preference-based measures, and some further specify a measure, such as EQ-5D. However, international guidelines are either unclear or lack detailed guidance regarding the collection (e.g. patients report own health), source (e.g. clinical trial) and usage (e.g. adjusting for comorbidities) of utility values. It is argued that there is a need for transparent and detailed international guidelines on utility data recommendations to provide decision makers with the best possible evidence. Where this is not possible it is recommended that best practice should be used to inform the collection, source and usage of utility values in HTA.

    This work focused on developing, fabricating, and fully calibrating a flowangle probe for aeronautics research by utilizing the latest microelectromechanical systems (MEMS), leadless silicon on insulator (SOI) sensor technology. While the concept of angle probes is not new, traditional devices had been relatively large due to fabrication constraints; often too large to resolve flow structures necessary for modern aeropropulsion measurements such as inlet flow distortions and vortices, secondary flows, etc. Mea surements of this kind demanded a new approach to probe design to achieve sizes on the order of 0.1 in. (.3 mm) diameter or smaller, and capable of meeting demanding requirements for accuracy and ruggedness. This approach invoked the use of stateof- the-art processing techniques to install SOI sensor chips directly onto the probe body, thus eliminating redundancy in sensor packaging and probe installation that have historically forced larger probe size. This also facilitated a better thermal match between the chip and its mount, improving stability and accuracy. Further, the leadless sensor technology with which the SOI sensing element is fabricated allows direct mounting and electrical interconnecting of the sensor to the probe body. This leadless technology allowed a rugged wire-out approach that is performed at the sensor length scale, thus achieving substantial sensor size reductions. The technology is inherently capable of high-frequency and high-accuracy performance in high temperatures and harsh environments.

    Self-sufficiency type houses are outlined. On condition that people gain a certain amount of income in relation with the society, they self-suffice under the given environment, allowing themselves to accept a minimum of industrial products with small environmental load. Ordinary supply from outside of fossil energy and materials which depend on it is minimized. Types are classified into three: energy, energy materials and perfect self-sufficiency. A study project for environment symbiotic houses is progressing which is planned by the Ministry of Construction and Institute of Building Energy Conservation and is invested by a private company. Its target is making a house for halving an environmental load by CO{sub 2}, for the purpose of creating the environment symbiotic house which is nice to and in harmony with the global environment and human beings. As a part of the studies on energy-saving and resource conservation on houses, introduced is a plan of an autonomous house at Izu-Atagawa. The passive method and high thermal-insulation are used for air conditioning, and hot spring water for hot water supply. Electric power is generated by hydroelectric power generation using mountain streams and by solar cells. Staple food is purchased, while subsidiary food is sufficed. 17 refs., 4 figs., 1 tab.

    When planning the Aging in Place Initiative at TigerPlace, it was envisioned that advances in technology research had the potential to enable early intervention in health changes that could assist in proactive management of health for older adults and potentially reduce costs. The purpose of this study was to compare length of stay (LOS) of residents living with environmentally embedded sensor systems since the development and implementation of automated health alerts at TigerPlace to LOS of those who are not living with sensor systems. Estimate potential savings of living with sensor systems. LOS for residents living with and without sensors was measured over a span of 4.8 years since the implementation of sensor-generated health alerts. The group living with sensors (n = 52) had an average LOS of 1,557 days (4.3 years); the comparison group without sensors (n = 81) was 936 days (2.6 years); p = .0006. Groups were comparable based on admission age, gender, number of chronic illnesses, SF12 physical health, SF12 mental health, Geriatric Depression Scale (GDS), activities of daily living, independent activities of daily living, and mini-mental status examination scores. Both groups, all residents living at TigerPlace since the implementation of health alerts, receive registered nurse (RN) care coordination as the standard of care. Results indicate that residents living with sensors were able to reside at TigerPlace 1.7 years longer than residents living without sensors, suggesting that proactive use of health alerts facilitates successful aging in place. Health alerts, generated by automated algorithms interpreting environmentally embedded sensor data, may enable care coordinators to assess and intervene on health status changes earlier than is possible in the absence of sensor-generated alerts. Comparison of LOS without sensors TigerPlace (2.6 years) with the national median in residential senior housing (1.8 years) may be attributable to the RN care coordination

    This work presents the new THOR technology (Total-House waste recycling) for the treatment of municipal solid wastes (RSU) and their conversion in Refuse Derived Fuel (RDF). THOR technology is based on the use of a mechanochemical reactor, which is high speed mill with an elevate milling mass/milled material ratio, applied to the wet and dry organic component of refuse. Transformations induced from mechanochemical reactor on refuse are: an almost complete drying process; a dimensional reduction with a final product with a D80 lower than 30 mm; an homogenizing and elimination of halogens combining themselves in saline form and a transfer of metallic ions. These ions can be binded to specific reagents during treatment in order to remove definitely them from the RDF produced. After treatment the output product is constituted by a dry material with a content of minimum total carbon upper than 65% and a content of total hydrogen equal to 12%, with a calorific power equal or upper than 4600 kcal/kg. Fuel so produced results to be without halogens and it has a sulphur content less than values indicated in the European standards. Ashes resulting from the burning of this product are poor in metals, because they are removed by mechanochemical treatment during the transformation process. Another positive element of this technology is the absence of emissions such as greenhouse gasses, NOX, powders and dioxin in atmosphere. Proofs carried out in lab-scale plant showed the practicability of the technology. The experimental plant realised with this technology will have a productivity of 3-5 ton/hour, and it will be suitable for the RSU treatment of a community of about 30.000-50.000 inhabitants. The system can be turned on or turned off in every moment by this particular technology, so that it becomes useful in all those cases in which wastes production is seasonal, as it happens in tourist areas. Another important feature is the possibility of carrying this plant directly near

    In our research project a suitable method has been developed related the technological aspect of the environmental assessment of land use changes caused by climate change. We have prepared an eco-balance (environmental inventory) to the environmental effects classification in life-cycle approach in connection with the typical agricultural / forest and tree utilization technologies. The use of balances and environmental classification makes possible to compare land-use technologies and their environmental effects per common functional unit. In order to test our environmental analysis model, we carried out surveys in sample of forest stands. We set up an eco-balance of the working systems of intermediate cutting and final harvest in the stands of beech, oak, spruce, acacia, poplar and short rotation energy plantations (willow, poplar). We set up the life-cycle plan of the surveyed working systems by using the GaBi 6.0 Professional software and carried out midpoint and endpoint impact assessment. Out of the results, we applied the values of CML 2001 - Global Warming Potential (GWP 100 years) [kg CO2-Equiv.] and Eco-Indicator 99 - Human health, Climate Change [DALY]. On the basis of the values we set up a ranking of technology. By this, we received the environmental impact classification of the technologies based on carbon footprint. The working systems had the greatest impact on global warming (GWP 100 years) throughout their whole life cycle. This is explained by the amount of carbon dioxide releasing to the atmosphere resulting from the fuel of the technologies. Abiotic depletion (ADP foss) and marine aquatic ecotoxicity (MAETP) emerged also as significant impact categories. These impact categories can be explained by the share of input of fuel and lube. On the basis of the most significant environmental impact category (carbon footprint), we perform the relative life cycle contribution and ranking of each technologies. The technological life cycle stages examined

    Solar energy systems were investigated which complement nuclear and coal technologies as a means of reducing the U.S. dependence on imported petroleum. Solar Thermal Energy Systems (STES) represents an important category of solar energy technologies. STES can be utilized in a broad range of applications servicing a variety of economic sectors, and they can be deployed in both near-term and long-term markets. The net present value of the energy cost savings attributable to electric utility and IPH applications of STES were estimated for a variety of future energy cost scenarios and levels of R&D success. This analysis indicated that the expected net benefits of developing an STES option are significantly greater than the expected costs of completing the required R&D. In addition, transportable fuels and chemical feedstocks represent a substantial future potential market for STES. Due to the basic nature of this R&D activity, however, it is currently impossible to estimate the value of STES in these markets. Despite this fact, private investment in STES R&D is not anticipated due to the high level of uncertainty characterizing the expected payoffs. Previously announced in STAR as N83-10547

    The use of exergy is described as a measure for identifying and explaining the benefits of green energy and technologies, so the benefits can be clearly understood and appreciated by experts and non-experts alike, and the utilization of green energy and technologies can be increased. Exergy can be used to assess and improve energy systems, and can help better understand the benefits of utilizing green energy by providing more useful and meaningful information than energy provides. Exergy clearly identifies efficiency improvements and reductions in thermodynamic losses attributable to green technologies. Exergy can also identify better than energy the environmental benefits and economics of energy technologies. Exergy should be utilized to engineers and scientists, as well as decision and policy makers, involved in green energy and technologies. (author)

    The salinity problem is one of the severe constraints for agriculture in Pakistan. In a socio-economic and salinity and drainage survey over an area of about 25000 acres of salt-affected land recently, crop production is found to be very low. Livestock is underfed and malnourished. Pakistan has spent and allocated over one billion US dollars on Salinity Control and Reclamation Projects (SCARP), of course, with dubious results. Over the years, a Saline Agriculture Technology has been developed as a cheap alternative at NIAB for comfortably living with salinity and to profitably utilize saline land rather than its reclamation. The soil improvement is a fringe benefit in this approach. The Saline Agriculture Technology has been tested at laboratory level, at field stations and at farms of some progressive farmers. Now we are sharing this technology with farming communities through a 'Saline Agriculture Farmer Participatory Development Project in Pakistan', with assistance from the National Rural Support Programme. The new project has been launched simultaneously in all four provinces of Pakistan on 25000 acres of salt-affected land. Under this project seeds of salt tolerant crop varieties wheat, cotton, rice, castor, brassica and barley and saplings of trees/shrubs, e.g. Acacia ampliceps, A. nilotica, Casuarina glauca, ber, jaman, etc selected for development work in various institutions of Pakistan are being provided to farmers. Know-how on new irrigation techniques like bed-and-corrugation and bed-and-furrow, agronomic practices like laser land leveling, planting on beds and in auger holes and soil/water amendment practices (use of gypsum and mineral acids) are being shared with farmers. These interventions are quite efficient, save water up to 40% and enable farmers to utilize bad quality water. In general, farmers are being familiarized with prevalent animal diseases, nutritional problems and prophylactic techniques. They are being helped in developing Saline

    Full Text Available More than 10 million tons of biodiesel fuel (BDF have been produced in the world from the transesterification of vegetable oil with methanol by using acid catalysts (sulfuric acid, H2SO4, alkaline catalysts (sodium hydroxide, NaOH or potassium hydroxide, KOH, solid catalysts and enzymes. Unfortunately, the price of BDF is still more expensive than that of petro diesel fuel due to the lack of a suitable raw material oil. Here, we review the best selection of BDF production systems including raw materials, catalysts and production technologies. In addition, glycerol formed as a by-product needs to be converted to useful chemicals to reduce the amount of glycerol waste. With this in mind, we have also reviewed some recent studies on the utilization of glycerol.

    The United States Department of Health and Human Services (DHHS) has emphasized the importance of utilizing health information technologies, thus making the availability of electronic resources critical for physicians across the country. However, few empirical assessments exist regarding the current status of computerization and utilization of electronic resources in physician offices and physicians' perceptions of the advantages and disadvantages of computerization. Through a survey of physicians' utilization and perceptions of health information technology, this study found that a "digital divide" existed for eastern North Carolina physicians in smaller physician practices. The physicians in smaller practices were less likely to utilize or be interested in utilizing electronic health records, word processing applications, and the Internet.

    Operation and utilization of the materials testing reactor BR2 at the Belgian Nuclear Research Centre (SCK·CEN) has since its start in 1963 always followed closely the needs and developments of nuclear technology. In particular, a multitude of irradiation experiments have been carried out for most types of nuclear power reactors, existing or under design. Since the early 1990s and increased focus was directed towards more specific irradiation testing needs for light water reactor fuels and materials, although other areas of utilization continued as well (e.g. fusion reactor materials, safety research, ...), including also the growing activities of radioisotope production and silicon doping. An important milestone was the decision in 1994 to implement a comprehensive refurbishment programme for the BR2 reactor and plant installations. The scope of this programme comprised very substantial studies and hardware interventions, which have been completed in early 1997 within planning and budget. Directly connected to this strategic decision for reactor refurbishment was the reinforcement of our efforts to requalify and upgrade the existing irradiation facilities and to develop advanced devices in BR2 to support emerging programs in the following fields: - LWR pressure vessel steel, - LWR irradiation assisted stress corrosion cracking (IASCC), - reliability and safety of high-burnup LWR fuel, - fusion reactor materials and blanket components, - fast neutron reactor fuels and actinide burning, - extension and diversification of radioisotope production. The paper highlights these advances in the areas of BR2 utilisation and the ongoing development activities for the required new generation of irradiations devices. (author)

    In order to carry out the selection of the nuclear power materials which are used in radiation, from high temperature to very low temperature, and in corrosive environment, and the development of the materials effectively, the construction of huge material data base is indispensable. The development of the distributed type material data base called 'freeway' is advanced jointly by National Research Institute for Metals, Japan Atomic Energy Research Institute, Power Reactor and Nuclear Fuel Development Corporation and Japan Science and Technology Corporation. It has been aimed at that the results obtained in each research institute are made into a data base by that institute, and those data bases can be utilized mutually through network. In fiscal year 1996, the transfer to the system, by which the function showing the contents of system data and the function of data retrieval can be utilized from internet, was begun jointly. The present state of the data freeway, the operation environment of World Wide Web, and the trial making of the computation program for forecasting the change of the chemical composition of materials by neutron irradiation are reported.

    Oxygen production from lunar raw materials is critical for sustaining a manned lunar base but is very power intensive. Solar concentrators are a well-developed technology for harnessing the Sun s energy to heat regolith to high temperatures (over 1375 K). The high temperature and potential material incompatibilities present numerous technical challenges. This study compares and contrasts different solar concentrator designs that have been developed, such as Cassegrains, offset parabolas, compound parabolic concentrators, and secondary concentrators. Differences between concentrators made from lenses and mirrors, and between rigid and flexible concentrators are also discussed. Possible substrate elements for a rigid mirror concentrator are selected and then compared, using the following (target) criteria: (low) coefficient of thermal expansion, (high) modulus of elasticity, and (low) density. Several potential lunar locations for solar concentrators are compared; environmental and processing-related challenges related to dust and optical surfaces are addressed. This brief technology survey examines various sources of thermal energy that can be utilized for materials processing on the lunar surface. These include heat from nuclear or electric sources and solar concentrators. Options for collecting and transporting thermal energy to processing reactors for each source are examined. Overall system requirements for each thermal source are compared and system limitations, such as maximum achievable temperature are discussed.

    Full Text Available Virtual Reality is fast becoming a breakthrough in education technology and is headed towards a path where learning has become immersive. Virtual reality (VR offers both learners and educators a great opportunity to bridge gaps in the pedagogical sense. With the emergence of the Google Cardboard (GCB platform, a low-cost, virtual reality gadget comes a wide range of opportunities for educators and institutions to bring about an immersive type of learning environment for the 21st-century learner. Using Grade 6 Middle school students, this research explores the learning outcomes and student reactions using the GCB and Google Expeditions application. The study showed no significant difference in pre-test scores of the control and experimental group. There is however, a significant difference in the scores of the experimental group compared to the control group after post-test. Utilizing t-test in comparing the two groups, it was found that the mean of the post-test scores for Group A (experimental was significantly higher than Group B(control. The result of the independent samples t-test was significant, t(18 = 2.33, p = .032, suggesting that the mean of posttest score was significantly different between Groups A and B. This difference in score performance gives light to how VR can be used as a tool that enhances the learning experience. By using VR technology that is low cost and effective, more institutions will be able to help students learn better.

    Given the increasing complexity of climate modeling and analysis tools, it is often difficult and expensive to build or recreate an exact replica of the software compute environment used in past experiments. With the recent development of new technologies for hardware virtualization, an opportunity exists to create full modeling, analysis and compute environments that are “archiveable”, transferable and may be easily shared amongst a scientific community or presented to a bureaucratic body if the need arises. By encapsulating and entire modeling and analysis environment in a virtual machine image, others may quickly gain access to the fully built system used in past experiments, potentially easing the task and reducing the costs of reproducing and verify past results produced by other researchers. Moreover, these virtual machine images may be used as a pedagogical tool for others that are interested in performing an academic exercise but don't yet possess the broad expertise required. We built two virtual machine images, one with the Community Earth System Model (CESM) and one with Weather Research Forecast Model (WRF), then ran several small experiments to assess the feasibility, performance overheads costs, reusability, and transferability. We present a list of the pros and cons as well as lessoned learned from utilizing virtualization technology in the climate and earth systems modeling domain.

    A new wireless transceiver is described for recording individual neuron firing from behaving rats utilizing Bluetooth transmission technology and a processor onboard for discrimination of neuronal waveforms and associated time stamps. This universal brain activity transmitter (UBAT) is attached to rodents via a backpack and amplifier headstage and can transmit 16 channels of captured neuronal firing data via a Bluetooth transceiver chip over very large and unconstrained distances. The onboard microprocessor of the UBAT allows flexible online control over waveform isolation criteria via transceiver instruction and the two-way communication capacity allows for closed-loop applications between neural events and behavioral or physiological processes which can be modified by transceiver instructions. A detailed description of the multiplexer processing of channel data as well as examples of neuronal recordings in different behavioral testing contexts is provided to demonstrate the capacity for robust transmission within almost any laboratory environment. A major advantage of the UBAT is the long transmission range and lack of object-based line of sight interference afforded by Bluetooth technology, allowing flexible recording capabilities within multiple experimental paradigms without interruption. Continuous recordings over very large distance separations from the monitor station are demonstrated providing experimenters with recording advantages not previously available with other telemetry devices.

  12. Advanced Reactor Technology Options for Utilization and Transmutation of Actinides in Spent Nuclear Fuel

    2009-09-01

    Renewed interest in the potential of nuclear energy to contribute to a sustainable worldwide energy mix is strengthening the IAEA's statutory role in fostering the peaceful uses of nuclear energy, in particular the need for effective exchanges of information and collaborative research and technology development among Member States on advanced nuclear power technologies (Articles III-A.1 and III-A.3). The major challenges facing the long term development of nuclear energy as a part of the world's energy mix are improvement of the economic competitiveness, meeting increasingly stringent safety requirements, adhering to the criteria of sustainable development, and public acceptability. The concern linked to the long life of many of the radioisotopes generated from fission has led to increased R and D efforts to develop a technology aimed at reducing the amount of long lived radioactive waste through transmutation in fission reactors or accelerator driven hybrids. In recent years, in various countries and at an international level, more and more studies have been carried out on advanced and innovative waste management strategies (i.e. actinide separation and elimination). Within the framework of the Project on Technology Advances in Fast Reactors and Accelerator Driven Systems (http://www.iaea.org/inisnkm/nkm/aws/fnss/index.html), the IAEA initiated a number of activities on utilization of plutonium and transmutation of long lived radioactive waste, accelerator driven systems, thorium fuel options, innovative nuclear reactors and fuel cycles, non-conventional nuclear energy systems, and fusion/fission hybrids. These activities are implemented under the guidance and with the support of the IAEA Nuclear Energy Department's Technical Working Group on Fast Reactors (TWG-FR). This publication compiles the analyses and findings of the Coordinated Research Project (CRP) on Studies of Advanced Reactor Technology Options for Effective Incineration of Radioactive Waste (2002

    Since the Vision for Space Exploration (VSE) was released in 2004, NASA, in conjunction with international space agencies, industry, and academia, has continued to define and refine plans for sustained and affordable robotic and human exploration of the Moon and beyond. With the goal of establishing a lunar Outpost on the Moon to extend human presence, pursue scientific activities, use the Moon to prepare for future human missions to Mars, and expand Earth s economic sphere, a change in how space exploration is performed is required. One area that opens up the possibility for the first time of breaking our reliance on Earth supplied consumables and learn to live off the land is In-Situ Resource Utilization (ISRU). ISRU, which involves the extraction and processing of space resources into useful products, can have a substantial impact on mission and architecture concepts. In particular, the ability to make propellants, life support consumables, and fuel cell reagents can significantly reduce the cost, mass, and risk of sustained human activities beyond Earth. However, ISRU is an unproven capability for human lunar exploration and can not be put in the critical path of lunar Outpost success until it has been proven. Therefore, ISRU development and deployment needs to take incremental steps toward the desired end state. To ensure ISRU capabilities are available for pre-Outpost and Outpost deployment by 2020, and mission and architecture planners are confident that ISRU can meet initial and long term mission requirements, the ISRU Project is developing technologies and systems in three critical areas: (1) Regolith Excavation, Handling and Material Transportation; (2) Oxygen Extraction from Regolith; and (3) Volatile Extraction and Resource Prospecting, and in four development stages: (I) Demonstrate feasibility; (II) Evolve system w/ improved technologies; (III) Develop one or more systems to TRL 6 before start of flight development; and (IV) Flight development for

    This paper focuses on how incumbent electric utilities strategically react to subsidy schemes supporting renewable energy technologies in the UK, Germany, and Spain. Firms coordinate the development of their technological capabilities and their political activities to shape their regulatory environment. Analysing the diffusion of wind power in these countries, we show that the different ways, in which firms coordinate their technological and political strategies, lead to very different market outcomes, both for the firms' market share and the size of the overall market. Although incumbents are usually seen as being resistant to change in energy systems, we show that Spanish utilities proactively drive the diffusion of wind power. We speculate about the relation between the ownership structure of the energy system and its inertia with respect to the integration of new technologies. We derive novel policy implications that explicitly take into account the strategic actions of incumbent firms shaping the technological and regulatory system

    benefits. Because it produces hot water by extracting heat from the air it tends to dehumidify and cool the room in which it is placed. Moreover, it tends to spread the water heating load across utility non-peak periods. Thus, electric utilities with peak load issues could justify internal programs to promote this technology to residential and commercial customers. For practical purposes, consumers are indifferent to the manner in which water is heated but are very interested in product attributes such as initial first cost, operating cost, performance, serviceability, product size, and installation costs. Thus, the principal drivers for penetrating markets are demonstrating reliability, leveraging the dehumidification attributes of the HPWH, and creating programs that embrace life-cycle cost principles. To supplement this, a product warranty with scrupulous quality control should be implemented; first-price reduction through engineering, perhaps by reducing level of energy efficiency, should be pursued; and niche markets should be courted. The first step toward market penetration is to address the HPWH's performance reliability. Next, the manufacturers could engage select utilities to aggressively market the HPWH. A good approach would be to target distinct segments of the market with the potential for the highest benefits from the technology. Communications media that address performance issues should be developed. When marketing to new home builders, the HPWH could be introduced as part of an energy-efficient package offered as a standard feature by builders of new homes within a community. Conducting focus groups across the United States to gather input on HPWH consumer values will feed useful data back to the manufacturers. ''Renaming'' and ''repackaging'' the HPWH to improve consumer perception, appliance aesthetics, and name recognition should be considered. Once an increased sales volume is achieved, the manufacturers

  17. From Natural Monopoly to Public Utility: Technological Determinism and the Political Economy of Infrastructure in Progressive-Era America.

    Science.gov (United States)

    Plaiss, Adam

    In present-day debates regarding telecommunication policy, one frequently hears the terms natural monopoly and public utility. This article investigates the origins of these ideas, finding that Richard T. Ely-a celebrated American economist of the late nineteenth century-embedded in the term "natural monopoly" a narrative of technological determinism. By arguing that certain services had monopolizing tendencies hardwired into them, Ely argued for their regulation. Ely's theory of natural monopoly formed the basis of Wisconsin's 1907 public utilities law, which served as a model for many other states' regulatory policies. The modern notion of public utility thus carries with it the technological determinism of Ely's natural monopoly idea. By tracing the lineage of these two terms, this article recaptures the influence that activists and progressive politicians exercised over the formation of large technological systems during the Second Industrial Revolution.

    Analysis of the application of modern remote sensing technologies in current research shows a significant increase in interest in fast and efficient detection of underground installations. The most important reasons of the said application are preventing damage during excavation works, as well as the formation of the cadastre of underground utilities suitable for operating and maintaining of such resources. Given the wide area of application in the detection of underground installations, ground penetrating radar scanning technology (GPR), in this instance, is used as prevalent method for the purpose of the acquisition radargram of pipelines and the comparison with the results of the acquisition of Unmanned Aerial Vehicle - UAV drone Aibot X6 equipped with Optris PI Lightweight Kit (which consists of a miniaturized lightweight PC and a weight-optimized PI450 Optris LW infrared camera). The aim of the research presented in the this paper is to analyze the benefits of integrating a mobile system capable of very fast, reliable and relatively inexpensive detection of heating pipelines using thermal imaging aerial inspection and GPR technology for control sampling of radargrams on specific locations of routes in order to achieve following: a simple identification of the characteristics of heating pipelines, prevention and registration of damage, as well as automated data extraction. The results of integrated application of the above-mentioned remote sensing technologies have shown that, within 10min of planned flight, it is possible to detect and georeference routes of heating pipelines in the area of 50.000m2 by application of thermal imaging inspection that assigns an adequate temperature value to each pixel in an image. The experiment showed that the registration is also possible in the case of pre-insulated and conventionally insulated heating pipes, and the difference in temperature measurements above the routes and the environment was up to 4 degrees. It should be

    The Lana'i Community Health Center (LCHC) like other health care organizations, is striving to implement technology-enabled care (TEC) in the clinical setting. TEC includes such technological innovations as patient portals, mobile phone applications, wearable health sensors, and telehealth. This study examines the utilization of communication technology by members of the Lana'i community and LCHC staff and board members in the home and in their daily lives and evaluates the community's electronic health literacy. Quantitative surveys and qualitative focus groups were utilized. These revealed that members of the Lana'i community and LCHC staff and board members regularly utilize technology, in the form of smart cell phones, WiFi, and internet texting. This community has integrated technology into their daily lives, even though they live on an isolated island with 3,102 people; however, despite this integration, the electronic health literacy of this population appears insufficient for proper understanding and utilization of TEC, limiting the potential of patient portals or remote monitoring of patient generated data for chronic disease prevention and management without additional education and mentoring. It is therefore in the best interest of the LCHC and other health organizations wishing to implement TEC in a rural community such as Lana'i to include a strong educational component with use of TEC, and perhaps establish a mentor/partnership program for the highly-challenged patient.

    The importance of efficiency in the supply chain of perishable products, such as the blood products used in transfusion services, cannot be overstated. Many problems can occur, such as the outdating of products, inventory management issues, patient misidentification, and mistransfusion. The purpose of this article was to identify the benefits and barriers associated with radiofrequency identification (RFID) usage in improving the blood bank supply chain. The methodology for this study was a qualitative literature review following a systematic approach. The review was limited to sources published from 2000 to 2014 in the English language. Sixty-five sources were found, and 56 were used in this research study. According to the finding of the present study, there are numerous benefits and barriers to RFID utilization in blood bank supply chains. RFID technology offers several benefits with regard to blood bank product management, including decreased transfusion errors, reduction of product loss, and more efficient inventory management. Barriers to RFID implementation include the cost associated with system implementation and patient privacy issues. Implementation of an RFID system can be a significant investment. However, when observing the positive impact that such systems may have on transfusion safety and inventory management, the cost associated with RFID systems can easily be justified. RFID in blood bank inventory management is vital to ensuring efficient product inventory management and positive patient outcomes.

    To examine whether low-income adults' utilization of Internet technology is predicted or mediated by health literacy, health numeracy, and computer assistance. Low-income adults (N = 131) from the midwestern United States were surveyed about their technology access and use. Individuals with low health literacy skills were less likely to use Internet technology (e.g., email, search engines, and online health information seeking), and those with low health numeracy skills were less likely to have access to Internet technology (e.g., computers and cell phones). Consistent with past research, males, older participants, and those with less education were less likely to search for health information online. The relationship between age and online health information seeking was mediated by participant literacy. The present study suggests that significant advances in technology access and use could be sparked by developing technology interfaces that are accessible to individuals with limited literacy skills.

    This paper reports the survey results on systems and peripheral technologies for use of PV power in fiscal 1994. On the case study of PV communities, as housing zone PV community, Seibu Kitanodai housing estate mainly composed of detached houses, and the Suwa area of Tama New Town of apartment houses were selected to study PV power generation on a roof, wall and window. The result clarified that generated energy of a detached house reaches 3-4 times as much as consumed one, that of an apartment house is nearly equal to consumed one, and power generation of nearly 380MW is possible based on expected housing supply until 2000. As urban core zone PV community, the survey result on Ebisu Garden Place clarified that the expected PV power supply rate is 10% or more, 20% and 30% or more for hotel and office buildings, high-rise apartment building more than 30 stories, and medium-rise one of 10 and several stories, respectively. In Sakura industrial estate, the maximum generated power was nearly equal to consumed power in a weekday, and as inverse power flow in a holiday was considered, the annual PV power supply rate was extremely high.

    Nowdays, due to the increasing importance of quality care, organizations focuse on the improving provision, management and distribution of health. On one hand, incremental costs of the new technologies and on the other hand, increased knowledge of health care recipients and their expectations for high quality services have doubled the need to make changes in order to respond to resource constraints (financial, human, material). For this purpose, several technologies, such as barcode, have been used in hospitals to improve services and staff productivity; but various factors effect on the adoption of new technologies and despite good implementation of a technology and its benefits, sometimes personnel don't accept and don't use it. This is an applied descriptive cross-sectional study in which all the barcode users in health information management department of the three academic hospitals (Feiz, Al-Zahra, Ayatollah Kashani) affiliated to Isfahan University of Medical Sciences were surveyed by the barcode technology acceptance questionnaire, in six areas as following: barcode ease of learning, capabilities, perception of its usefulness and its ease of use, users attitudes towards its using, and users intention. The finding showed that barcode technology total acceptance was relatively desirable (%76.9); the most compliance with TAM model was related to the user perceptions about the ease of use of barcode technology and the least compliance was related to the ease of learning barcode technology (respectively %83.7 and %71.5). Ease of learning and barcode capability effect of usefulness and perceived ease of barcode technology. Users perceptions effect their attitudes toward greater use of technology and their attitudes have an effect on their intention to use the technology and finally, their intention makes actual use of the technology (acceptance). Therefore, considering the six elements related to technology implementation can be important in the barcode

    Information and Communication Technology (ICT) and Organizational Innovation (OI) are seen as the miracle of post-modernity in organizations. In this way, they are supposed to resolve most organizational problems, efficiently and rapidly. OI is highly dependent on the capacity and the investment in knowledge management (internal and external) to support decision making process and to implement significant changes. We know what explains ICT utilization (ICTU) and what determines OI development (OID) in healthcare services. Moreover, the literature tends to link ICTU to OID and vice versa. However, this dependency has never been explored empirically through the lens of roles combination. To identify the existing combined roles profiles of ICTU and OID among healthcare decision makers and determine factors of the shift from a profile to another. We did the following: (1) a structured review of the literature on healthcare management by focusing on ICTU and OID which allowed us to build two indexes and a comprehensive framework; (2) a copula methodology to identify with high precision the thresholds for ICTU and OID; and (3) a cross-sectional study based on a survey done with a sample of 942 decision makers from Canadian healthcare organizations through a multinomial logit model to identify determinants of the shift. ICTU and OID are correlated at 22% (Kendal's Tau). The joint distribution (combination) of ICTU and OID shows that four major profiles exist among decision makers in Canadian healthcare organizations: the traditional decision maker, the innovative decision maker, the technologic decision maker and the contemporary decision maker. We found out that classic factors act as barriers to the shift from one profile to the desired profile (from 1 to 4, from 2 to 4 and from 3 to 4). We have identified that the attitude toward research and relational capital are transversal barriers of shift. We have also found that some factors have a specific impact such as

    The House of Commons Science and Technology Committee has issued a series of non-dogmatic recommendations. Also regarding elective sex selection, it has adopted a controversial position. Sex selection should be allowed for family balancing. However, the acceptability of preimplantation genetic diagnosis as a method for selecting the embryos can be questioned on the basis of social harm. In countries with a shortage of medical personnel and a limited health care budget, elective procedures are a loss to society. This loss should be compensated by imposing a 'social compensation tax' for every application of elective sexing.

    Recent efforts have been directed towards utilizing CAD/CAM technology in the education of future dentists. The purpose of this pilot study was to investigate the feasibility of implementing CAD/CAM technology in instruction on preparing a tooth for restoration. Students at one dental school were assigned access to CAD/CAM technology vs. traditional preparation methods in a randomized, crossover design. In a convenience sample of a second-year class, seventy-six of the seventy-nine students volunteered to participate, for a response rate of 96 percent. Two analyses were performed on this pilot data: a primary effectiveness analysis comparing students' competency exam scores by intervention group (intention-to-treat analysis) and a secondary efficacy analysis comparing competency exam scores among students who reported using CAD/CAM versus those who did not. The effectiveness analysis showed no difference in outcomes by intervention group assignment. While student survey results indicated interest in utilizing the technology, the actual utilization rate was much less than one might anticipate, yielding a sample size that limited statistical power. The secondary analysis demonstrated higher mean competency exam scores for students reporting use of CAD/CAM compared to those who did not use the technology, but these results did not reach statistical significance (p=0.075). Prior research has investigated the efficacy of CAD/CAM in a controlled educational trial, but this study adds to the literature by investigating student use of CAD/CAM in a real-world, self-study fashion. Further studies should investigate ways in which to increase student utilization of CAD/CAM and whether or not increased utilization, with a larger sample size, would yield significant outcomes.

    Although the importance of risk communication has been pointed out over the last decade in nuclear community, both public authorities and nuclear industry have not conducted the definite actions yet. It will be reflected in the public eye that nuclear community's attitude toward communication and consultation with the public about risk issues is half-hearted, comparing with chemical and food safety fields which recently launched their risk communication activities. In this study, we conduct risk communication experiments on some risk issues associated with nuclear technology and its utilization in Tokai village, for the purpose of establishment of risk communication in our society that might be one of the new relationships between science and technology and society. The outcomes of FY2002 study are the following threefold; 1) preparation of risk communication experiments on nuclear technology and its utilization, 2) assessment of social effects of risk communication activities, 3) preparation of practical guidebook for risk communication experiments.

    Housing/lack of housing and HIV are powerfully linked. Housing occupies an important place in the causal chains linking poverty and inequality, and HIV risk and outcomes of infection. The articles in this Special Supplement of AIDS and Behavior confirm the impact of homelessness, and poor or unstable housing, on HIV/AIDS, and challenge scientists to test and policy makers to implement the promise of housing as an innovative response to the epidemic. In order to influence the development of policies on housing to benefit at-risk or HIV-infected persons, however, proponents must justify why this association exists, and how housing can help end the epidemic as well as improve the care and health of persons living with HIV/AIDS. We introduce this supplement with a discussion of the "why" question.

    2018-04-01

    A tunnel FET (TFET) is a candidate replacement for conventional MOSFETs to realize low-power LSI. The most significant issue with the practical application of TFETs concerns their low tunneling current. Si is an indirect-gap material with a low band-to-band tunneling probability and is not favored for the channel. However, a new technology has recently been proposed to enhance the tunneling current in Si-TFETs by utilizing isoelectronic trap (IET) technology. IET technology provides an innovative approach to realizing low-power LSI with TFETs. In this paper, state-of-the-art research on Si-TFETs with IET technology from the viewpoint of process and device integration is reviewed.

    2013-01-01

    Modern aircraft employ a significant fraction of their weight in composite materials to reduce weight and improve performance. Aircraft aeroservoelastic models are typically characterized by significant levels of model parameter uncertainty due to the composite manufacturing process. Small modeling errors in the finite element model will eventually induce errors in the structural flexibility and mass, thus propagating into unpredictable errors in the unsteady aerodynamics and the control law design. One of the primary objectives of Multi Utility Technology Test-bed (MUTT) aircraft is the flight demonstration of active flutter suppression, and therefore in this study, the identification of the primary and secondary modes for the structural model tuning based on the flutter analysis of MUTT aircraft. The ground vibration test-validated structural dynamic finite element model of the MUTT aircraft is created in this study. The structural dynamic finite element model of MUTT aircraft is improved using the in-house Multi-disciplinary Design, Analysis, and Optimization tool.

    International Nuclear Information System (INIS)

    Shaw, Isabel; Ozaki, Ritsuko

    2015-01-01

    Making housing developments ‘environmentally sustainable’ requires housing developers to be accountable for their ‘green’ credentials. Accountability is promoted by both the UK government's environmental policy for housing design – the Code for Sustainable Homes – and local councils in their planning criteria. These accountability practices are key to how relationships between housing professionals and local planning authorities influence practices and outcomes of environmental sustainability. In this article, we examine how accountability is performed in housing design and development. We argue that accountability practices involve the management of making environmental sustainability visible through demonstrating the utilization of sustainable technologies. We contend that these ‘visibility’ practices are carried out to the detriment of an appreciation of how energy is both provided and consumed. We contend that using the installation phase of sustainable technologies as a point of adequate assessment of the environmental effectiveness of a building is short-sighted. Policy needs to look beyond this, and consult with professionals who develop and sell houses to understand better their working priorities and contexts that shape the provision of renewable energy in the planning phase and post-build. - Highlights: • Accountability practices shape environmental sustainability practices and outcomes. • Making sustainability ‘visible’ involves the use of sustainable technologies. • Policy should consider how it affects professionals work and energy provision. • Visibility practices influence energy provision and potential consumption.

    In pursuit of such missions as Apollo, the National Aeronautics and Space Administration has called into being unique equipment that obviously has little direct application beyond the achievement of mission objectives. Yet, to assume that further direct application of space program hardware is somehow a measure of the industrial benefits accruing to the nation is to misunderstand how the creation of new technology affects modern industrial capability. This document presents a profile of the significant ways in which technological developments in response to aerospace mission requirements have been coupled into industrial practice, with the result being that improved products and processes are now being utilized to benefit the nation.

    In this work, we evaluate technologies that will enable solar photovoltaics (PV) to overcome the limits of traditional electric power systems. We performed simulations of a large utility system using hourly solar insolation and load data and attempted to provide up to 50% of this system's energy from PV. We considered several methods to avoid the limits of unusable PV that result at high penetration due to the use of inflexible baseload generators. The enabling technologies considered in this work are increased system flexibility, load shifting via demand responsive appliances, and energy storage

    As an undergraduate researcher, I worked on a new technology called nanofluid-based direct absorption solar collectors (DASC) which is a type of solar water heater that has the potential to be more efficient than traditional solar water heaters. Because of my experience with this type of technology, I decided to look into other types of solar energy technologies which could be used on Native American tribal lands. Some types of solar energy technologies that I wanted to focus on are photovoltaic solar energy systems, passive solar design, and solar water heaters.

    Despite the relatively huge ICT investment and policy deployment in higher institutions in Ethiopia, there is still scant information about the success of implementation of the Information Communication Technology (ICT) in the higher education. This study, therefore, was carried out with an aim to assess knowledge and utilization of Information Communication Technology (ICT) among medicine and health science students and its associated factors in Gondar College of Medicine and Health sciences, University of Gondar. A cross-sectional study was conducted at the College of Medicine and Health Sciences, University of Gondar, Ethiopia. Data regarding socio-demographic characteristics of the students, level of knowledge and utilization of ICT were collected by means of a self-administered questionnaire. Data was analyzed using SPSS version 13. A total of 1096 students responded giving a response rate of 97.8%. The mean age of the study participants was 20.3 (±1. 3) years. Females constitute only 26% of the respondents. The majority (79%) were fulltime students. Only half of the respondents (51%) had ICT knowledge and only 46% students utilized ICT while 47% of the respondents never used electronic communication (e.g. email or chat room) and 39% of the respondents never used Microsoft office (e.g. word (®) or WordPerfect (®)). ICT knowledge [AOR = 2.5, 95% CI: 1.7-3.5], family educational background [AOR = 4.36, 95% CI: 2.16-8.80], and perceived quality of training [AOR = 1.9, 95% CI: 1.3-2.8] showed strong and positive associations with ICT utilization. Students from urban areas were more likely to utilize ICT compared with those from rural areas [AOR = 2.7, 95% CI: 2.097, 3.497], and information technology training was found to be positively associated with ICT utilization [AOR = 2. 07, 95% CI: 1.18, 3.62]. The result showed that students' knowledge was inadequate and utilization of ICT was poor. Therefore, the university should sustain professional development to

    Full Text Available This paper describes the result of a project to develop climate adaptation design strategies funded by the UK’s Technology Strategy Board. The aim of the project was to look at the threats and opportunities presented by industrialized and house-building techniques in the light of predicted future increases in flooding and overheating due to anthropogenic climate change. The paper shows that the thermal performance of houses built to the current UK Building Regulations is not adequate to cope with changing weather patterns, and in light of this, develops a detailed design for a new house: one that is industrially produced and climatically resilient, but affordable. This detailed concept IDEAhaus of a modular house is not only flood-proof to a water depth of 750 mm, but also is designed to utilize passive cooling, which dramatically reduces the amount of overheating, both now and in the future.

    2015-01-01

    Full Text Available In the period from 1948 to 1970 urban housing architecture in Yugoslavia had a distinctly experimental character as it strived intensively towards research and establishment of new architectural patterns and values that would mark the period of economic growth of the country. In conditions of mass housing construction, initiated by the devastated urban housing fund after the Second World War, significant influx of population to towns and the state directed its socialist aspirations at alloting every family acceptable living space. The period of the so-called “directed housing construction“, whose imperative was to establish the limits of existential minimum in collective housing, maximal space “packing“ and optimal functionality of flats, at the same time represents the most significant period in the development of housing architecture in Yugoslavia. The architects focused their interests in housing in mainly three directions: a the creation and application of new prefabrication systems, b innovative application of modernistic patterns in aestheticization of architecture and c experimenting with space units which will enable a higher level of privacy in high-density housing conditions. The first direction of research emerged in the context of post-war housing construction of a wide scope, which encouraged the advance of technological research in areas of prefabrication and practical application of achieved results on the whole territory of Yugoslavia. The second direction dealt with architectural planning which was strictly subordinated to social and ideological sphere with domineering socialist monumentalism and artistic and sculptural approach to architecture. The third was related to experimental tendency with new urban housing patterns which aimed to search and find more pragmatic, humane solutions within mass high-density housing constructions which were the first to utilize and show examples of “double-tract” buildings.

    The construction principle of solar power facade collectors - one edge profile, two intermediate profiles, thermally separated aluminium frames and wood back wall allow the coupling in a post-bar system 'light' with profile width of only 40 mm. In addition sizes ranging up to 200 x 500 cm can be chosen, which enables a complete cover of the desired facade surface without underconstruction, a cover of the thermal bridges created by edge beams and a simple inclusion of existing openings. A final conclusion is made that according to the knowledge of the author, the attempt was made for the first time to construct a complete building facade not only as a passive element (insulation values of the walls meeting passive house standards are achieved) but also as an energetic active element of a residential building.

    2013-12-01

    Full Text Available In the United States, there is no comprehensive energy policy at the federal level. To address issues as diverse as climate change, energy security, and economic development, individual states have increasingly implemented Renewable Portfolio Standards (RPSs, which mandate that utility providers include a specified amount of electricity from renewable energy sources in their total energy portfolios. Some states have included incentives for individual energy technologies in their RPS, such as solar electric (also called photovoltaic or PV technology. Here, we use GIS to visualize adoption of RPSs and electricity generation from renewable energy sources in the US and examine changes in renewable electricity and solar electric generation over time with the goal of informing future policies aimed at promoting the adoption of renewable energy technologies.

    ScanPlot{sup SM} gamma spectroscopy land survey system was utilized for the overland survey of uranium at the Sun Rose Claim in the Northwest Territories. The Sun Rose Claim is a former uranium exploration site and previous investigations had identified uranium ore and waste rock. ScanPlot{sup SM} radiological scan surveys were performed utilizing a backpack system. ScanPlot{sup SM} platform utilized spectroscopy grade sodium iodide detectors configured for optimal spatial coverage and radiation detection. Survey locations were recorded using an on-board global positioning system (GPS). The radiological spectral data from the radiation detectors is automatically logged and linked with the GPS coordinates to an on-board computer to create isocontour figures using a color scale to represent radioactivity levels. The advantage of utilizing the ScanPlot{sup SM} system for this assessment is that the nature and extent of uranium is provided without having to collect and assay a large number of samples.

    2011-01-01

    Much focus is given to the energy efficiency of dwellings, in policy and regulation, in pursuance of reduced CO 2 emissions for sustainability. This article examines a terrace of 6 similar, passive solar dwellings with sunspaces and the effects that occupants' behaviours have on their energy efficiency. It was found that average annual space heating demand was less than expected, indicating potential benefits from measuring passive solar gains as a form of renewable energy. Space heating demand per person varied by a factor of up to 14 between dwellings dependent on occupant behaviour. Further evidence showed a factor of 45 possible. Significant behaviours in this dwelling type were identified. A second study used 31 personal ecological footprint (PEF) accounts to assess the significance of dwelling energy efficiency in terms of environmental sustainability. A comparison was made between residents of contemporary eco-homes and practising permaculturists occupying a range of traditional house types. It was found that the PEF of the average eco-home dweller was 1.6 times higher than that of the permaculturists. It is argued that improved education for sustainability would be a more efficient way to reduce domestic energy demand than currently recognised. - Highlights: → Quantifies improvements to dwelling energy efficiency from behaviour and education. → Assesses balance of dwelling energy efficiency and sustainability. → Suggests education for sustainability be used more to reduce energy demand. → Indicates research directions to assess budgets for education in sustainability. → Identifies significant behaviour affecting energy efficiency with sunspace use.

  8. UTILIZING INNOVATIVE TECHNOLOGIES FOR ENVIRONMENTAL CLEAN-UP, SAVAHHAH RIVER SITE

    Energy Technology Data Exchange (ETDEWEB)

    Bergren, C

    2009-01-07

    The Savannah River Site (SRS) is a 310-square-mile United States Department of Energy nuclear facility located along the Savannah River near Aiken, South Carolina. During operations, which started in 1951, hazardous substances (chemicals and radionuclides) were released to the environment. The releases occurred as a result of inadvertent spills and waste disposal in unlined pits and basins which was common practice before environmental regulations existed. The hazardous substances have migrated to the vadose zone and groundwater in many areas of the SRS, resulting in 515 waste units and facilities that are required by environmental regulations, to undergo characterization and, if needed, remediation. In the initial years of the SRS environmental cleanup program (early 1990s), the focus was to use common technologies (such as pump and treat, air stripping, excavation and removal) that actively and tangibly removed contamination. Exclusive use of these technologies required continued and significant funding while often failing to meet acceptable clean-up goals and objectives. Recognizing that a more cost-effective approach was needed, SRS implemented new and complementary remediation methods focused on active and passive technologies targeted to solve specific remediation problems. Today, SRS uses technologies such as chemical/pH-adjusting injection, phytoremediation, underground cutoff walls, dynamic underground stripping, soil fracturing, microbial degradation, baroballs, electrical resistance heating, soil vapor extraction, and microblowers to more effectively treat contamination at lower costs. Additionally, SRS's remediation approach cost effectively maximizes cleanup as SRS works proactively with multiple regulatory agencies. Using GIS, video, animation, and graphics, SRS is able to provide an accurate depiction of the evolution of SRS groundwater and vadose zone cleanup activities to convince stakeholders and regulators of the effectiveness of various

    The Energy & Environmental Research Center (EERC) is conducting a consortium-based effort directed toward resolving the mercury (Hg) control issues facing the lignite industry. Specifically, the EERC team--the EERC, EPRI, URS, ADA-ES, Babcock & Wilcox, the North Dakota Industrial Commission, SaskPower, and the Mercury Task Force, which includes Basin Electric Power Cooperative, Otter Tail Power Company, Great River Energy, Texas Utilities (TXU), Montana-Dakota Utilities Co., Minnkota Power Cooperative, BNI Coal Ltd., Dakota Westmoreland Corporation, and the North American Coal Company--has undertaken a project to significantly and cost-effectively oxidize elemental mercury in lignite combustion gases, followed by capture in a wet scrubber. This approach will be applicable to virtually every lignite utility in the United States and Canada and potentially impact subbituminous utilities. The oxidation process is proven at the pilot-scale and in short-term full-scale tests. Additional optimization is continuing on oxidation technologies, and this project focuses on longer-term full-scale testing. The lignite industry has been proactive in advancing the understanding of and identifying control options for Hg in lignite combustion flue gases. Approximately 1 year ago, the EERC and EPRI began a series of Hg-related discussions with the Mercury Task Force as well as utilities firing Texas and Saskatchewan lignites. This project is one of three being undertaken by the consortium to perform large-scale Hg control technology testing to address the specific needs and challenges to be met in controlling Hg from lignite-fired power plants. This project involves Hg oxidation upstream of a system equipped with an electrostatic precipitator (ESP) followed by wet flue gas desulfurization (FGD). The team involved in conducting the technical aspects of the project includes the EERC, Babcock & Wilcox, URS, and ADA-ES. The host sites include Minnkota Power Cooperative Milton R. Young

    Health care disparities and high chronic disease rates burden many communities and disproportionally impact racial/ethnic populations in the United States. These disparities vary geographically, increase health care expenses, and result in shortened lifespans. Digital technologies may be one tool for addressing health disparities and improving population health by increasing individuals' access to health information-especially as most low-income U.S. residents gain access to smartphones. The Aetna Foundation partners with organizations to use digital technologies, including mobile applications, data collection, and related platforms, for learning and sharing. Projects range from the broad-childhood education, lifestyle modification, health IT training, and nutrition education, to the specific-local healthy foods, stroke rehabilitation, and collection of city-level data. We describe our approaches to grantmaking and discuss lessons learned and their implications. When combined with sound policy strategies, emerging, scalable, digital technologies will likely become powerful allies for improving health and reducing health disparities.

  13. Technologies for utilizing natural resources create new job opportunities in the geosciences in developing countries

    Science.gov (United States)

    Aswathanarayana, U.

    Water, soils, minerals, and biota constitute a community's most significant natural resources. Innovations in technology are generating new jobs in converting into a resource what was yesterday a non-resource; in developing process and control technologies to minimize wastes; and in waste recycling.“Resources are not, they become,” in the words of Zimmerman. In the case of the developing countries, the technologies of choice have not only to be ecologically sustainable and economically viable, but more importantly, employment generating. The new kinds of jobs—for example, in poverty alleviation projects via micro-enterprises based on value-added processing of natural resources—have a strong environmental relevance and tend to lie at the interface of several traditional scientific disciplines. Geoscience graduates in the developing countries are best placed to take advantage of these new job opportunities involving Earth materials, but only if they are exposed to broad-based geoscience instruction.

    2015-10-15

    Estimating potential of CO{sub 2} emission reduction of non-capture CO{sub 2} utilization (NCCU) technology was evaluated. NCCU is sodium bicarbonate production technology through the carbonation reaction of CO{sub 2} contained in the flue gas. For the estimating the CO{sub 2} emission reduction, process simulation using process simulator (PRO/II) based on a chemical plant which could handle CO{sub 2} of 100 tons per day was performed, Also for the estimation of the indirect CO{sub 2} reduction, the solvay process which is a conventional technology for the production of sodium carbonate/sodium bicarbonate, was studied. The results of the analysis showed that in case of the solvay process, overall CO{sub 2} emission was estimated as 48,862 ton per year based on the energy consumption for the production of NaHCO{sub 3} (7.4 GJ/tNaHCO{sub 3}). While for the NCCU technology, the direct CO{sub 2} reduction through the CO{sub 2} carbonation was estimated as 36,500 ton per year and the indirect CO{sub 2} reduction through the lower energy consumption was 46,885 ton per year which lead to 83,385 ton per year in total. From these results, it could be concluded that sodium bicarbonate production technology through the carbonation reaction of CO{sub 2} contained in the flue was energy efficient and could be one of the promising technology for the low CO{sub 2} emission technology.

  13. The diversification value of nuclear power as part of a utility technology mix when gas and carbon prices are uncertain

    2005-01-01

    Despite recent revived interest, the prospects for new nuclear power investment in liberalized electricity industries without government support do not seem promising. The objective of this paper is twofold. First it aims to identify the specific features of nuclear power technology that makes it an unattractive choice. The second objective is to estimate the value to a utility of a nuclear investment as a hedge against uncertain gas and carbon prices. A stylized 5-plant Real Option utility model shows that while the nuclear option value represents about 18% of the net present value (NPV) of the nuclear plant investment in the case where electricity and gas prices are uncorrelated, it reduces to nearly zero for correlation factors between electricity and gas price greater than 30%. These results suggest that the private diversification incentives in electricity markets might not be aligned with the social value of a diverse fuel-mix at the country level. (Author)

    The aim of this study was to identify the most widely used financial, productivity, and accessibility metrics used by academic radiology departments (ARDs) in a dashboard format via a national survey. The results provide a guide to the selection of preferred or commonly used indicators to facilitate dashboard implementation and use. The study met the criteria for an exemption from institutional review board approval. A cross-sectional survey was conducted using a survey approved by the Society of Chairs of Academic Radiology Departments and sent to its members. The survey was designed to evaluate the adoption, access, and composition of dashboard technology in ARDs, particularly those related to measures of productivity and financial performance. The overall response rate was 42% (56 of 131 members). Sixty-two percent of responding ARDs currently use some form of dashboard technology, but 50% have used this technology for ≤2 years. Sixty-five percent of all ARDs use their dashboard information on a monthly basis. The two dashboard financial indicators most frequently used by ARDs are revenue and actual expenses. Similarly, the two productivity indicators used most widely are total examination volume and examination volume per modality. The two most important access indicators used are report turnaround time and backlog per unit time. Currently, fewer than two-thirds of the responding ARDs use dashboard technology, and one-half have used the technology for ≤2 years. Although some fiscal and productivity indices are more frequently used, there are a diverse number of factors used to measure productivity, finance, access, and other operational parameters in ARD dashboards. Thus, the information provided by each institutional dashboard may be significantly different from that in other ARDs. Copyright © 2013 American College of Radiology. Published by Elsevier Inc.

    This paper reports living comfort in summer by operating a groundwater utilization system using a hot water storage tank and a floor air conditioning system. The groundwater utilization system is a system for room cooling by using groundwater and for supplying water for living use. The system operates as follows: groundwater is passed through a coil-type heat exchanger having pipes each 100 m long laid in parallel for a total length of 200 m, the heat exchanger being installed in a hot water storage tank; the water is used to cool water in the storage tank in summer; and the water is warmed up in the storage tank in winter, further heated by an oil boiler to be used as hot water for cooking and bathing. In the floor air conditioning system, cold water in the water storage tank (warm water in winter) is pumped up by a circulation pump, and passed through the floor air conditioning circuit having a pipe with a total length of 400 m at a flow rate of 14 liters per minute. The system is of a closed circuit in which the water is re-heated by a wood burning boiler in winter and returned to the hot water storage tank. The amount of supplied cold heat from groundwater to the hot water tank obtained on a daily average is 90W. About 20% of the monthly cumulative cold heat amount dissipated from the floor circuit is the monthly cumulative cold heat amount supplied from the groundwater circuit to the hot water storage tank. 1 ref., 10 figs., 1 tab.

    Telepsychiatry was introduced in the early 1950's for the provision of mental health services from a distance. In 1990 the progress made in telecommunications technologies caused a significant expansion in telepsychiatry services. It can refer to store and forward technologies, interactive technologies, remote monitoring technologies and it is applied to contribute to the lift of restrictions placed on providing mental health services. Restrictions may exist due to geographic isolation, lack of specialized services, high cost of moving patients etc. The positive cost-benefit analysis and the reliability of diagnosis and efficacy of interventions through telepsychiatry have been documented in various research papers referring to a wide range of contexts such as prisons, remote areas, general and psychiatric hospitals. Since 2003 the Mobile Mental Health Unit of South- Eastern (SE) Cyclades has been using videoconferencing in order to provide mental health services in thirteen islands. This area shares many of the characteristics of remote areas such as residential dispersion, lack of mental health services and frequent lack of access to services in urban centers. Telepsychiatry in conjunction with physical presence of professionals was launched by the Mobile Mental Health Unit in order to provide assistance to the evaluation of patients, to therapeutic interventions, to medicine prescription, to crisis intervention, to psychoeducation of patients and their families and to the implementation of educational and administrative activities . The use of existing technology in combination with the development of human resources has enabled continuity of care, crisis intervention and avoidance of involuntary hospitalization for a significant number of persons. Moreover, it has improved cooperation and coordination between the interdisciplinary team and local authorities and agencies. When professionals located in different parts are collaborating via telepsychiatry it is

  19. Passive houses in Norway

    Energy Technology Data Exchange (ETDEWEB)

    Halse, Andreas

    2008-12-15

    The paper analyzes the introduction of passive houses in the Norwegian house market. Passive houses are houses with extremely low levels of energy consumption for heating, and have not yet been built in Norway, but have started to enter the market in Germany and some other countries. The construction sector is analyzed as a sectoral innovation system. The different elements of the innovation system are studied. This includes government agencies, producers, consumers, finance and education. The analysis shows that passive and low-energy houses are on the verge of market breakthrough. This can partly be explained by economic calculations, and partly by processes of learning and change in the institutional set-up of the sector. The construction sector is a sector characterized by low innovative intensity and little interaction between different agents. Those working to promote passive houses have to some extent managed to cope with these challenges. This has happened by breaking away from the traditional focus of Norwegian energy efficiency policies on technology and the economically rational agents, by instead focusing on knowledge and institutional change at the level of the producers.

    At this point in time, the stalled growth in the U.S. nuclear industry is leading to contractions in the nuclear supply base. Uranium mines have closed down, or sold out to larger mining companies, or merged. U.S. fuel fabricators have teamed up with counterparts in Europe Service companies and reactor manufacturers are also merging, both in the U.S. and Europe. With the stalled growth in nuclear, the large, primary producers are no longer able to continuously expand the SWU price, as DOE did, with Congress' support up through the early eighties. Against this industry trend, it is gratifying to see the several examples of entrepreneurship in the enrichment industry. Several of these efforts are represented by my colleagues on this panel today. New technologies: CRISLA, AVLIS, and SILVA are being developed. New models of older technologies are being deployed: LES and the Japanese centrifuge projects

    Full Text Available The enormous potential of agro biomass can be exploited to produce sustainable bioenergy. Proper management and further exploitation of this potential could lead to economically profitable approximations and solutions for the agricultural industry and even energy production industry. Gasification in-situ with energy production or pyrolysis of the above mentioned residues, under a non-oxidizing atmosphere for alternative fuels production could be a solution to the environmental problems that land filling or conventional combustion could create. The present work focuses on combustion and pyrolysis of cotton gin residues in Greece, as an alternative way of energy production. The purpose of presentation of a case study of the two alternatives methods (combustion and gasification or pyrolysis, by using cotton ginning waste as biofuel, is to show the appropriateness of new bioenergy sources by coupling them with energy production technologies. These technologies can be applied in northern Greece as well as in other Balkan or Mediterranean countries. .

    With financial support from the German Minister of Research and Technology (BMFT) two German companies have developed two GPS-C/A-Code-receivers for different applications with low weight and small volume. The measured results of positions in connection with the ABS of a car (Anti lock braking system) and in Diff.-GPS-mode are very satisfying and in the range of 15 and/or 3 meters. Both receivers worked quite well and both companies have demonstrated their capability to meet our high exspectations. Unfortunately the GPS-satellite to be launched are behind schedule, therefore the two German companies cannot sell their products and if the GPS-system will be completed in the year 1991 other technologies with smaller and cheaper receivers will be on the market.

    2017-01-01

    Full Text Available Due to high-mud content in superfine unclassified tailings (SUT, the viscosity of cemented paste backfill (CPB is high and its pipeline transportation properties are poor. Foaming technology was introduced to prepare a new three-phase flow backfill (TFB using a foaming machine. Then the rheological parameters of TFB with different bubble ratio were measured and their pipeline transportation properties were simulated by Fluent. Besides, the simulation results were further verified by a semi-industrial loop test. The results indicate that the optimum ratio of TFB is a cement-sand ratio of 1 : 8, mass concentration of 70%, and bubble ratio of 20%. Compared with CPB, the decrease of bleeding rate, viscosity, and resistance loss of TFB is 27%, 25%, and 30%, respectively. Therefore, foaming technology is an innovative and feasible solution for high-mud CPB in reducing viscosity, decreasing resistance loss, and improving pipeline transporting efficiency.

    In this two year project, the research team investigated how delayed γ-rays from short-lived fission fragments detected in the short interval between irradiating pulses can be exploited for advanced safeguards technologies. This program contained experimental and modeling efforts. The experimental effort measured the emitted spectra, time histories and correlations of the delayed γ-rays from aqueous solutions and solid targets containing fissionable isotopes. The modeling effort first developed and benchmarked a hybrid Monte Carlo simulation technique based on these experiments. The benchmarked simulations were then extended to other safeguards scenarios, allowing comparisons to other advanced safeguards technologies and to investigate combined techniques. Ultimately, the experiments demonstrated the possible utility of actively induced delayed γ-ray spectroscopy for fissionable material assay.

    As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

With the pursuit of this technological achievement, the ability to care for mankind in the areas of cardiac surgery has been made possible. Heart disease can affect anyone within the general population, but one such segment that it can affect from inception includes children. Currently, congenital heart defects are the most common birth defects nationally and worldwide. A large meta-analysis study from 1930 to 2010 was conducted in review of published medical literature totaling 114 papers with a study population of 24,091,867 live births, and divulged a staggering incidence of congenital heart disease involving 164,396 subjects with diverse cardiac illnesses. The prevalence of these diseases increased from 0.6 per 1,000 live births from 1930–1934 to 9.1 per 1,000 live births after 1995. These data reveal an emphasis on a growing public health issue regarding congenital heart disease. This discovery displays a need for heightened awareness in the scientific and medical industrial community to accelerate investigative research on emerging cardiovascular devices in an effort to confront congenital anomalies. One such device that has evolved over the past several decades is the pediatric membrane oxygenator. The pediatric membrane oxygenator, in conjunction with the heart lung

    Radioiodinated mIBG is finding increasing utility in nuclear medicine. However, its widespread use in developing countries is precluded by logistic constraints owing to the relative instability of the labelled molecule with respect to time and temp., and high costs. This prompted us to develop a low cost in-house batch process technology that could be used for the small-scale preparation of 131 I-mIBG even in a less equipped hospital-based radiopharmacy. The production of large amounts of 131 I-mIBG for clinical use requires sophisticated infrastructure (a scarce resource) to contain / safeguard against internal and external radiation exposures. We have indigenously designed a semi-automated, self-shielded, remote-controlled and safe microplant + process assemblies using easily accessible and cheap inputs, and developed the complete technology for the rapid and safe production of dual dosage forms of 131 I-mIBG, a radiotherapeutic (R x ) single dosage form of high activity along with 1-3 low activity radiodiagnostics (D x ) as multidosage forms. The radioiodide exchange reaction was effected in the solid / melt phase at 190 deg. C in 1.0 h. The radiolabelling yield was ∼80.0-86.0%, and the radiochemical purity > 99.5% and specific activity of R x /D x =900-1300/60-800 MBq ( x dosage forms at 3 weeks. The dosage forms (especially R x ) were only made against firm patient appointment(s). Thus far we have prepared 14 R x (49.0 GBq) and 70 + 14 batches (43.43 GBq) of (∼150 nos.) D x forms, and used them in 14 and > 1100 patients respectively. (author)

    This is the Phase 11 Final Report on NREL Subcontract No. XR-2-11175-1 {open_quotes}Advanced Hydrogen/Methane Utilization Demonstration{close_quotes} between the National Renewable Energy Laboratory (NREL), Alternative Fuels Utilization Program, Golden, Colorado and Hydrogen Consultants, Inc. (HCI), Littleton, Colorado. Mr. Chris Colucci was NREL`s Technical Monitor. Colorado State University`s (CSU) Engines and Energy Conversion Laboratory was HCI`s subcontractor. Some of the vehicle test work was carried out at the National Center for Vehicle Emissions Control and Safety (NCVECS) at CSU. The collaboration of the Colorado School of Mines is also gratefully acknowledged. Hydrogen is unique among alternative fuels in its ability to burn over a wide range of mixtures in air with no carbon-related combustion products. Hydrogen also has the ability to burn on a catalyst, starting from room temperature. Hydrogen can be made from a variety of renewable energy resources and is expected to become a widely used energy carrier in the sustainable energy system of the future. One way to make a start toward widespread use of hydrogen in the energy system is to use it sparingly with other alternative fuels. The Phase I work showed that strong affects could be achieved with dilute concentrations of hydrogen in methane (11). Reductions in emissions greater than the proportion of hydrogen in the fuel provide a form of leverage to stimulate the early introduction of hydrogen. Per energy unit or per dollar of hydrogen, a greater benefit is derived than simply displacing fossil-fueled vehicles with pure hydrogen vehicles.

  14. Dry fermentation technology for utilization of Bio-energy crops/crop residues for biogas production

    Full Text Available Indian state Punjab produces 160 lakh tones of paddy every year. More than this quantity of paddy, straw is also produced which is not properly utilized. Paddy is burnt in the farmer’s fields itself, which produces lot of smoke and atmospheric pollution. Farmers have their own difficulty for burning this valuable straw as they have to vacate the fields for the next crop. Biogas production is one alternative for the individual farmer, for individual village or on the regional basis. In our opinion, it is possible to digest paddy straw anaerobically for biogas production and the digested humus would be utilized as crop manure. Anaerobic digestion of crop waste cannot be done by conventional anaerobic process for biogas production because of the floating characteristics of paddy straw in water. New process of anaerobic digestion has to be followed with small quantity of water to avoid floating of paddy straw. This process is commonly known as dry fermentation. This technique is well known in United States, Taiwan, German and Sri Lanka. In these countries, steel containers are being used as digester for anaerobic digestion. Digester of steel is ideal but the cost involved is very huge. Attempts have been made at PAU to construct masonry structure as digester but lot of difficulties were being faced to make it gas tight. The PAU has found suitable method to make the digester strong and gas tight. The life of structure will be more than 15 years. The advantage of the masonry structure is that the whole structure will be underground on which cold would have little effect in winter. This process of Dry Fermentation is a batch process, once the digester is loaded and activated, would produce sufficient gas for a period of 3 - 4 months. Therefore, 2 sets of digester are required to meet the whole year demand.

    Computerized information technology and process control systems supplying operators with integrated and graphically represented information possibly increase the safety of nuclear power plant operation. Advantages and disadvantages of this kind of man-machine interface are summarized. As shown by a detailed investigation, main features of such interfaces are not covered by current German regulations concerning the ergonomic design of control-rooms or visual display terminals. Problems of qualifying hard- and software for safety related applications are also discussed in detail. Because of these problems, computerized process control systems may be utilized in German nuclear power plants only in addition to the conventional instrumentation and during normal operation. The situation is compared with the state of the art and developments in France and Canada. It will be shown: - What specific problems arise if computerized information and control systems are to be licensed - how a reliable operation of the plant can be achieved with hybrid interfaces utilizing both conventional and computerized technology - what research activities are needed in order to solve the licensing problems - how to put these proposals into practice.

    In the early 90's GE recognized the need to introduce new technology to follow on to the ''F'' technology the Company introduced in 1988. By working with industry and DOE, GE helped shape the ATS program goal of demonstrating a gas turbine, combined-cycle system using natural gas as the primary fuel that achieves the following targets: system efficiency exceeding 60% lower heating value basis; environmental superiority under full-load operating conditions without the use of post-combustion emissions controls, environmental superiority includes limiting NO(sub 2) to less than 10 parts per mission by volume (dry basis) at 15% oxygen; busbar energy costs that are 10% less than current state-of-the-art turbine systems meeting the same environmental requirements; fuel-flexible designs operating on natural gas but also capable of being adapted to operate on coal-based, distillate, or biomass fuels; reliability-availability-maintainability (RAM) that is equivalent to modern advanced power generation systems; and commercial systems that could enter the market in the year 2000

    The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the US Department of Energy (DOE) is the development of the GE 7H and 9H combined cycle power systems. The major effort will be expended on detail design. Validation of critical components and technologies will be performed including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE`s request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. This report summarizes work accomplished in 1Q98.

    The LIGHTEnUP Analysis Tool (Lifecycle Industry GreenHouse gas, Technology and Energy through the Use Phase) has been developed for The United States Department of Energy’s (U.S. DOE) Advanced Manufacturing Office (AMO) to forecast both the manufacturing sector and product life-cycle energy consumption implications of manufactured products across the U.S. economy. The tool architecture incorporates publicly available historic and projection datasets of U.S. economy-wide energy use including manufacturing, buildings operations, electricity generation and transportation. The tool requires minimal inputs to define alternate scenarios to business-as-usual projection data. The tool is not an optimization or equilibrium model and therefore does not select technologies or deployment scenarios endogenously. Instead, inputs are developed exogenous to the tool by the user to reflect detailed engineering calculations, future targets and goals, or creative insights. The tool projects the scenario’s energy, CO2 emissions, and energy expenditure (i.e., economic spending to purchase energy) implications and provides documentation to communicate results. The tool provides a transparent and uniform system of comparing manufacturing and use-phase impacts of technologies. The tool allows the user to create multiple scenarios that can reflect a range of possible future outcomes. However, reasonable scenarios require careful attention to assumptions and details about the future. This tool is part of an emerging set of AMO’s life cycle analysis (LCA) tool such as the Material Flows the Industry (MFI) tool, and the Additive Manufacturing LCA tool.

    Innovation Partners proposed and successfully demonstrated in this SBIR Phase I grant a software/hardware co-design approach to reduce both the difficulty and time to implement Field Programmable Gate Array (FPGA) solutions to data acquisition and specialized computational applications. FPGAs can require excessive time for programming and require specialized knowledge that will be greatly reduced by the company's solution. Not only are FPGAs ideal for DAQ and embedded solutions, they can also be the best solution to specialized signal processing to replace Digital Signal Processors (DSPs). By allowing FPGA programming to be done in C with the equivalent of a simple compilation, algorithm changes and improvements can be implemented decreasing the life-cycle costs and allow subsitution of new FPGA designs staying above the technological details.

    Time, cost, and most importantly quality of data are the three factors to measure the success of field radiological characterizations. The application of coupling radiation detection instrumentation to a GPS receiver has dramatically increased the data quality achievable compared to traditional environmental radiological survey methods. Improvements in verifying adequate spatial coverage of an area while collecting data and at,the same time reducing field time requirements can be realized. Data acquired during the recent implementation of the Mobile Surface Contamination Monitor 11 (MSCM-11) will be presented to demonstrate the advantages of this system over traditional radiological survey methods. The comparison will include time and manpower requirements. Linking the complimentary GPS, GIS and radiation detection technologies on a mobile tractor based platform has provided a tool to provide radiological characterization data faster, cheaper, and better to assist in the Environmental Restoration Mission of the Hanford Site

    Universal Aggregates, LLC proposes to design, construct and operate a lightweight aggregate manufacturing plant at the Birchwood Power Facility in King George, Virginia. The installation and start-up expenses for the Birchwood Aggregate Facility are $19.5 million. The DOE share is $7.2 million (37%) and the Universal Aggregates share is $12.3 (63%). The project team consists of CONSOL Energy Inc., P.J. Dick, Inc., SynAggs, LLC, and Universal Aggregates, LLC. The Birchwood Facility will transform 115,000 tons per year of spray dryer by-products that are currently being disposed of in an offsite landfill into 167,000 tons of a useful product, lightweight aggregates that can be used to manufacture lightweight aggregates that can be used to manufacture lightweight and medium weight masonry blocks. In addition to the environmental benefits, the Birchwood Facility will create nine (9) manufacturing jobs plus additional employment in the local trucking industry to deliver the aggregate to customers or reagents to the facility. A successful demonstration would lead to additional lightweight aggregate manufacturing facilities in the United States. There are currently twenty-one (21) spray dryer facilities operating in the United States that produce an adequate amount of spray dryer by-product to economically justify the installation of a lightweight aggregate manufacturing facility. Industry sources believe that as additional scrubbing is required, dry FGD technologies will be the technology of choice. Letters from potential lightweight aggregate customers indicate that there is a market for the product once the commercialization barriers are eliminated by this demonstration project.

    Background Information technology is transforming healthcare communication. Using smartphones to remotely monitor incisional wounds via digital photos as well as collect post-operative symptom information has the potential to improve patient outcomes and transitional care. We surveyed a vulnerable patient population to evaluate smartphone capability and willingness to adopt this technology. Methods We surveyed 53 patients over a 9-month period on the vascular surgery service at a tertiary-care institution. Descriptive statistics were calculated to describe survey item response. Results 94% (50 out of 53) of recruited patients participated. The cohort was 50% female, and the mean age was 70 years old (range: 41–87). The majority of patients owned cellphones (80%) and 23% of these cellphones were smartphones. 90% of patients had a friend or family-member that could help take and send photos with a smartphone. 92% of patients reported they would be willing to take a digital photo of their wound via smartphone (68% daily, 22% every-other day, 2% less than every-other day, 8% not at all). All patients reported they would be willing to answer questions related to their health via smartphone. Patient’s identified several potential difficulties with regard to adopting a smartphone wound-monitoring protocol including logistics related to taking photos, health-related questions, and coordination with caretakers. Conclusions Our survey demonstrates that an older patient cohort with significant comorbidity is able and willing to adopt a smartphone-based post-operative monitoring program. Patient training and caregiver participation will be essential to the success of this intervention. PMID:26025626

    1997-12-01

    A conceptual design for a water treatment system to reduce pollutants in manhole and vault water is presented as an alternative to current water disposal practices. Runoff and groundwater seepage that collects in vaults and manholes contains, or is likely to contain, concentrations of pollutants in excess of regulatory guidelines. Pollutants commonly present in storm water runoff consist of lead, cadmium, oil, grease and asbestos. The conceptual design presents the basis for a water treatment system that will reduce pollutant concentrations to levels below regulatory thresholds. The water treatment system is relatively inexpensive, small and simple to operate. A strainer is used to remove gross particulates, which are then stored for disposal. Utilizing centrifugal force, vault and manhole water is separated into constituent fractions including fine particulates, inorganics and oils. Fine particulates are stored with gross particulates for disposal. Chemical fixation is used to stabilize inorganics. Organic substances are stored for disposal. The water treatment system uses a granular activated carbon filter as an effluent polish to adsorb the remaining pollutants from the effluent water stream. The water can be discharged to the street or storm drain and the pollutants are stored for disposal as non-hazardous waste. This system represents a method to reduce pollutant volumes, reduced disposal costs and reduce corporate environmental liability. It should be noted that the initial phase of the development process is still in progress. This report is presented to reflect work in progress and as such should be considered preliminary

    Full Text Available Agricultural production and quality are adversely affected by various abiotic stresses worldwide and this will be exacerbated by the deterioration of global climate. To feed a growing world population, it is very urgent to breed stress-tolerant crops with higher yields and improved qualities against multiple environmental stresses. Since conventional breeding approaches had marginal success due to the complexity of stress tolerance traits, the transgenic approach is now being popularly used to breed stress-tolerant crops. So identifying and characterizing the the critical genes involved in plant stress responses is an essential prerequisite for engineering stress-tolerant crops. Far beyond the manipulation of single functional gene, engineering certain regulatory genes has emerged as an effective strategy now for controlling the expression of many stress-responsive genes. Transcription factors (TFs are good candidates for genetic engineering to breed stress-tolerant crop because of their role as master regulators of many stress-responsive genes. Many TFs belonging to families AP2/EREBP, MYB, WRKY, NAC, bZIP have been found to be involved in various abiotic stresses and some TF genes have also been engineered to improve stress tolerance in model and crop plants. In this review, we take five large families of TFs as examples and review the recent progress of TFs involved in plant abiotic stress responses and their potential utilization to improve multiple stress tolerance of crops in the field conditions.

    Full text: Radiation protection is the science of protecting people and the environment from the harmful effects of ionizing radiation, which includes both particle radiation and high energy electromagnetic radiation. It includes occupational radiation protection, which is the protection of workers; medical radiation protection, which is the protection of patients; and public radiation protection, which is about protection of individual members of the public, and of the population as a whole. ICT has made possible the development of e-learning and several Virtual Learning Environments (VLEs) which can support a wide range of capacity building requirements, ranging from under-graduate and post-graduate programmes, continuing professional development courses, right through to short subject specific and research courses, thereby eliminating the problems of conventional forms of training / learning, some of which are: limited access, cost effectiveness and language / cultural barriers. This paper focuses on the utilization of these ICT-based training / learning for capacity building in radiation protection framework and concludes with suggestions on implementation strategies.

  13. Assessing the utility of geospatial technologies to investigate environmental change within lake systems.

    Over 50% of the world's population live within 3 km of rivers and lakes highlighting the on-going importance of freshwater resources to human health and societal well-being. Whilst covering c. 3.5% of the Earth's non-glaciated land mass, trends in the environmental quality of the world's standing waters (natural lakes and reservoirs) are poorly understood, at least in comparison with rivers, and so evaluation of their current condition and sensitivity to change are global priorities. Here it is argued that a geospatial approach harnessing existing global datasets, along with new generation remote sensing products, offers the basis to characterise trajectories of change in lake properties e.g., water quality, physical structure, hydrological regime and ecological behaviour. This approach furthermore provides the evidence base to understand the relative importance of climatic forcing and/or changing catchment processes, e.g. land cover and soil moisture data, which coupled with climate data provide the basis to model regional water balance and runoff estimates over time. Using examples derived primarily from the Danube Basin but also other parts of the World, we demonstrate the power of the approach and its utility to assess the sensitivity of lake systems to environmental change, and hence better manage these key resources in the future.

    Simulated practice may improve resident performance in endoscopic endonasal surgery. Using the NeuroTouch haptic simulation platform, we evaluated resident performance and assessed the effect of simulation training on performance in the operating room. First- (N=3) and second- (N=3) year residents were assessed using six measures of proficiency. Using a visual analog scale, the senior author scored subjects. After the first session, subjects with lower scores were provided with simulation training. A second simulation served as a task-learning control. Residents were evaluated in the operating room over six months by the senior author-who was blinded to the trained/untrained identities-using the same parameters. A nonparametric bootstrap testing method was used for the analysis (Matlab v. 2014a). Simulation training was associated with an increase in performance scores in the operating room averaged over all measures (p=0.0045). This is the first study to evaluate the training utility of an endoscopic endonasal surgical task using a virtual reality haptic simulator. The data suggest that haptic simulation training in endoscopic neurosurgery may contribute to improvements in operative performance. Limitations include a small number of subjects and adjudication bias-although the trained/untrained identity of subjects was blinded. Further study using the proposed methods may better describe the relationship between simulated training and operative performance in endoscopic Neurosurgery. Copyright © 2016 Elsevier Ltd.

    Garbage problem is often very complex in urban areas. The handling pattern of collecting, transporting and disposing that has been applied up to this day has not yet produced an appropriate solution. This is evident from the data of statistic centre institution in 2015 that 76.31% of the existing waste in the community has not been sorted, while 10.28% sorted to be used and 13.41% sorted to be discarded, showing the community amount of unsorted garbage large enough to necessitate managerial efforts at the waste sources. In designing a systematic and structured waste management system, the generations, compositions, and characteristics of the waste are indispensable. Therefore, a research is conducted on these three dimensions to the non-domestic waste in Semarang City, which involves commercial waste (from the markets, restaurants, and hotels), institutional waste (from the offices and schools). From the research result the average of 0,24kgs/person/day in weight unit of the City's non-domestical waste generation is derived. The waste composition is dominated by organic waste of around 61.95%, while the rest percentage is inorganic. The management policy is directed with the application of Management Information System model based on Information Technology because of the system's abilities to effectuate the waste management.

    Safety is one of the most important factors in the field of aviation. Though, modern aircraft are equipped with many instruments/devices to enhance the flight safety but it is seen that accidents/incidents are never reduced to zero. Analysis of the statistical summary of Commercial Jet Airplane accidents highlights that fatal accidents that occurred worldwide from 2006 through 2015 is 11% during taxing, loading/unloading, parking and towing. Human, handling the aircrafts is one of the most important links in aircraft maintenance and hence play a significant role in aviation safety. Effort has been made in this paper to obviate human error in aviation and outline an affordable system that monitors the uneven surface &obstacles for safe "towing in" and "towing out" of an aircraft by the ground crew. The system revolves around implementation of sonar technology by microcontroller. Ultrasonic sensors can be installed on aircraft wings and tail section to identify the uneven surface &obstacles ahead and provide early warning to the maintenance ground crews.

  17. Experimental Investigation of Concrete Runway Snow Melting Utilizing Heat Pipe Technology

    2018-01-01

    Full Text Available A full scale snow melting system with heat pipe technology is built in this work, which avoids the negative effects on concrete structure and environment caused by traditional deicing chemicals. The snow melting, ice-freezing performance and temperature distribution characteristics of heat pipe concrete runway were discussed by the outdoor experiments. The results show that the temperature of the concrete pavement is greatly improved with the heat pipe system. The environment temperature and embedded depth of heat pipe play a dominant role among the decision variables of the snow melting system. Heat pipe snow melting pavement melts the snow completely and avoids freezing at any time when the environment temperature is below freezing point, which is secure enough for planes take-off and landing. Besides, the exportation and recovery of geothermal energy indicate that this system can run for a long time. This paper will be useful for the design and application of the heat pipe used in the runway snow melting.

    2015-03-01

    The purpose of this study is to determine attitudes of doctors of chiropractic regarding the importance of staff training in specific skill areas to inform the curriculum management process of a chiropractic technology program. A survey was distributed to registrants of a chiropractic homecoming event. On a 5-point Likert scale, respondents were asked to rate the degree of importance that staff members be trained in specific skills. Descriptive statistics were derived, and a 1-way analysis of variance (ANOVA) was used to test differences between groups based on years in practice and level of staff training. Doctors place a high level of importance on oral communication skills and low importance on nutrition and physical examinations. Comparing groups based on years in practice revealed differences in the areas of passive physiotherapies (F = 3.61, p = .015), legal issues/regulations (F = 3.01, p = .032), occupational safety and health regulation (F = 4.27, p = .006), and marketing (F = 2.67, p = .049). Comparing groups based on level of staff training revealed differences in the areas of occupational safety and health regulations (F = 4.56, p = .005) and cardiopulmonary resuscitation (F = 4.91, p = .003). With regard to their assistants, doctors of chiropractic tend to place high importance on office skills requiring effective communication and place less importance on clinical skills such as physical examinations and physiotherapy.

    Two new schemes for TcO 4 - /MoO 4 2- separations from OH - and MoO 4 2- media using polyethylene glycol (PEG)-based aqueous biphasic systems (ABS) have been developed. The two most important salt solutions in current 99m Tc-generator technologies, OH - and MoO 4 2- , also salt out PEG to form ABS. In liquid/liquid PEG- ABS, pertechnetate can be separated from molybdate with separation factors as high as 10,000. Stripping is accomplished by reduction of the TcO 4 - and back extraction into a salt solution. the strip solution can be the salt of an imaging agent (e.g., Na 4 HEDPA) and thus may, under the appropriate conditions, be injected directly into the human body. 99m TcO 4 - can also be concentrated from a dilute load solution of 99 MoO 4 2- in NaOH using an aqueous biphasic extraction chromatographic technique (ABEC). A rinse with K 2 CO 3 assures that all 99 MoO 4 2- is removed from the column and this is confirmed by a rapid drop in 99 Mo activity by the fourth free column volume (fcv) of rinse. The 99m TcO 4 - is then eluted with water. This chromatographic separation affords 94% of the 99m TcO 4 - activity in 5 fcv, with the y spectrum showing less than 2 x 10 -4 of the original 99 Mo activity

    The interest in solar cell technology among Danish house owners is increasing, but there are many considerations to be made before the house owner choose to install solar cells on the house. Major barriers are the solar cell systems' price and appearance. This interdisciplinary development project will show that both aesthetic and economic advantages can be derived from integrating solar cells already when the first sketches of the house are being made. In order to promote utilization of solar cells in Denmark the solutions must be attractive, both economically and aesthetically. Therefore the solar cell solutions in this project are developed in preparation for marketing both as an aesthetic expression and a high-technological, green and prestigious element. (BA)

It is considered that reduction of melatonin secretion under the blue light exposure from smartphone displays is one of the causes. The viewing distance may cause sleep disturbance, because the viewing distance determines the screen illuminance and/or asthenopia. However, to date, there has been no study closely investigating the impact of viewing distance on sleep; therefore, we sought to determine the relationship between smartphone viewing distance and subjective sleep status. Twenty-three nursing students (mean age ± standard deviation of 19.7±3.1 years participated in the study. Subjective sleep status was assessed using the Pittsburgh Sleep Quality Index, morningness–eveningness questionnaire, and the Epworth sleepiness scale. We used the distance between the head and the hand while holding a smartphone to measure the viewing distance while using smartphones in sitting and lying positions. The distance was calculated using the three-dimensional coordinates obtained by a noncontact motion-sensing device. The viewing distance of smartphones in the sitting position ranged from 13.3 to 32.9 cm among participants. In the lying position, it ranged from 9.9 to 21.3cm. The viewing distance was longer in the sitting position than in the lying position (mean ± standard deviation: 20.3±4.7 vs 16.4±2.7, respectively, P<0.01. We found that the short viewing

    In July 2009, a group of twenty-six K-12 teachers investigated an abandoned cemetery in Prairie View, Texas, utilizing ground-penetrating radar (GPR) to image the subsurface and handheld global positioning system (GPS) units and a total station to record surface positions. The teachers were participants in a summer course at Rice University, ESCI 515: Geophysical Field Work for Educators. The course met for 8 full days over a two week period. During this time, the group acquired and interpreted 53 GPR profiles and over 700 GPS positions. The results of the study were presented to the Prairie View community at the end of the two weeks, and our data will be used in their effort to obtain a historical site designation for the cemetery. Wyatt Chapel Cemetery is located adjacent to the campus of Prairie View A&M University in Prairie View, TX, and is thought to have originated as a slave burial ground in the 1850’s. There are very few markers remaining, but a previous ESCI 515 course (in summer 2007) discovered multiple unmarked burials using GPR, which were confirmed by subsequent excavations. This past summer, ESCI 515 participants acquired GPR profiles in previously unexplored areas, used a total station to accurately record the positions of surface features such as headstones, and used handheld GPS units to map the location of a nearby stream bed. Participants were in-service K-12 teachers from urban Houston school districts where the majority of students are members of historically underrepresented minority groups. Recruitment efforts targeted educators who are currently teaching science without a science degree. Participants included elementary, middle and high school teachers. This summer experience is followed by a content-intensive academic year course in Physical Geology. Participants experienced the process of science first-hand and used science for community service (i.e. restoring an abandoned cemetery). Through background research, they derived a rich

  4. Novel Pulping Technology: Directed Green Liquor Utilization (D-GLU) Pulping

    The general objectives of this new project are the same as those described in the original proposal. Conventional kraft pulping technologies will be modified for significant improvements in pulp production, such as strength, bleachability, and yield by using green liquor, a naturally high, kraft mill-derived sulfidity source. Although split white liquor sulfidity and other high sulfidity procedures have the promise of addressing several of the latter important economic needs of pulp mills, they require considerable engineering/capital retrofits, redesigned production methods, and thus add to overall mill expenditures. Green liquor use, however, possesses the required high sulfidity to obtain in general the benefits attributable to higher sulfidity cooking, without the required capital constraints for implementation. Before introduction of green liquor in our industrial operations, a stronger understanding of its fundamental chemical interaction with the lignin and carbohydrates in US hardwood and softwoods must be obtained. In addition, its effect on bleachability, enhancement of pulp properties, and influence on the overall energy and recovery of the mill requires further exploration before the process witnesses widespread mill use in North America. Thus, proof of principle will be accomplished in this work and the consequent effect of green liquor and other high sulfide sources on the pulping and bleaching operations will be explored for US kraft mills. The first year of this project will generate the pertinent information to validate its ability for implementation in US pulping operations, whereas year two will continue this work while proceeding to analyze pulp bleachability and final pulp/paper properties and develop a general economic and feasibility analysis for its eventual implementation in North America.

    There have been calls to restrict access to fertility treatment in women above a certain body mass index (BMI). It is important to consider public expectations before formulating policy. The study objective was to assess public opinion regarding provision of assisted reproductive technology (ART) to obese (BMI>30 kg/m(2)) women in the United States. The study was conducted through an Internet-based survey of U.S. residents ages 18-75. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression to describe predictors of response based on demographic characteristics. Of the 1049 respondents, 60.7% support the use of ART in obese women. Adjusting for age and gender, the odds of support were over twice as high in participants with BMI>40 kg/m(2) as in normal-weight respondents (OR=2.87, 95% CI=1.28-6.44). Fifty-five percent of participants supported a BMI limit for access to ART. Both increasing education (p-value=0.02) and BMI (p-value=0.01) were inversely associated with support of a BMI limit. Individuals who had themselves used ART were also less likely (OR=0.27, 95% CI=0.07--0.99) to support a BMI limit. In an Internet-based survey, participants who are in favor of ART are likely to support its use among obese women. More than 50% of these respondents also support implementation of a BMI limit for access to these services.

  7. Utilizing nanobody technology to target non-immunodominant domains of VAR2CSA.

    Full Text Available Placental malaria is a major health problem for both pregnant women and their fetuses in malaria endemic regions. It is triggered by the accumulation of Plasmodium falciparum-infected erythrocytes (IE in the intervillous spaces of the placenta and is associated with foetal growth restriction and maternal anemia. IE accumulation is supported by the binding of the parasite-expressed protein VAR2CSA to placental chondroitin sulfate A (CSA. Defining specific CSA-binding epitopes of VAR2CSA, against which to target the immune response, is essential for the development of a vaccine aimed at blocking IE adhesion. However, the development of a VAR2CSA adhesion-blocking vaccine remains challenging due to (i the large size of VAR2CSA and (ii the extensive immune selection for polymorphisms and thereby non-neutralizing B-cell epitopes. Camelid heavy-chain-only antibodies (HcAbs are known to target epitopes that are less immunogenic to classical IgG and, due to their small size and protruding antigen-binding loop, able to reach and recognize cryptic, conformational epitopes which are inaccessible to conventional antibodies. The variable heavy chain (VHH domain is the antigen-binding site of camelid HcAbs, the so called Nanobody, which represents the smallest known (15 kDa intact, native antigen-binding fragment. In this study, we have used the Nanobody technology, an approach new to malaria research, to generate small and functional antibody fragments recognizing unique epitopes broadly distributed on VAR2CSA.

    Many kinds of scientific technology have been used in the archaeological research. Especially the methodologies relevant to radiation and isotope have contributed to archaeology, giving a lot of scientific information. Among these methodologies, the radiocarbon dating, proposed by Willard Libby, has the greatest contribution since 1950. In Japan some scientists introduced this dating method immediately after Libby's proposal. As the result, the start of the Jomon period, in which the rope pattern was applied for decoration of earthenware, was reconsidered to be about 10,000 years ago. Yoshimasa Takashima mastered this technique and did the dendrochronological study at University of Washington, Seattle, from 1960 to 1961. After that he started the radiocarbon dating in Kyushu University, Fukuoka. First he employed the proportional gas counter to measure 14 C, requiring the complicated and time-consuming preparation of sample. When he restarted the radio-carbon dating with the authors in 1994 at Kyushu Environmental Evaluation Association (KEEA), he adopted the liquid scintillation counting method combined with the benzene synthesis from sample. Because this method is so convenient, many laboratories have adopted it as the conventional method in Japan. Since 1994, almost 100 samples have been treated every year in KEEA by this method. However this requires considerably much amount of sample, for example 20g in the case of wood. So that, in case of only small amount of sample can be obtained or a valuable sample is subjected to measurement, this method cannot be applicable. To resolve this problem, the accelerator mass spectrometer (AMS) has been used widely. In this method the atoms of 14 C are counted directly, getting the high sensitivity and requiring very small amount of sample (order of mg). Recently, in KEEA, the radiocarbon dating using AMS was started under the cooperation with Center for Applied Isotope Studies (CAIS), University of Georgia. Another work of

    Small modeling errors in the finite element model will eventually induce errors in the structural flexibility and mass, thus propagating into unpredictable errors in the unsteady aerodynamics and the control law design. One of the primary objectives of Multi Utility Technology Test Bed, X-56A, aircraft is the flight demonstration of active flutter suppression, and therefore in this study, the identification of the primary and secondary modes for the structural model tuning based on the flutter analysis of X-56A. The ground vibration test validated structural dynamic finite element model of the X-56A is created in this study. The structural dynamic finite element model of the X-56A is improved using a model tuning tool. In this study, two different weight configurations of the X-56A have been improved in a single optimization run.

    In anticipation of increased utility-scale solar energy development over the next 20 to 50 years, federal agencies and other organizations have identified a need to develop comprehensive long-term monitoring programs specific to solar energy development. Increasingly, stakeholders are requesting that federal agencies, such as the U.S. Department of the Interior Bureau of Land Management (BLM), develop rigorous and comprehensive long-term monitoring programs. Argonne National Laboratory (Argonne) is assisting the BLM in developing an effective long-term monitoring plan as required by the BLM Solar Energy Program to study the environmental effects of solar energy development. The monitoring data can be used to protect land resources from harmful development practices while at the same time reducing restrictions on utility-scale solar energy development that are determined to be unnecessary. The development of a long-term monitoring plan that incorporates regional datasets, prioritizes requirements in the context of landscape-scale conditions and trends, and integrates cost-effective data collection methods (such as remote sensing technologies) will translate into lower monitoring costs and increased certainty for solar developers regarding requirements for developing projects on public lands. This outcome will support U.S. Department of Energy (DOE) Sunshot Program goals. For this reason, the DOE provided funding for the work presented in this report.

    The House Committee on Science, Space, and Technology asked NASA to study software development issues for the space station. How well NASA has implemented key software engineering practices for the station was asked. Specifically, the objectives were to determine: (1) if independent verification and validation techniques are being used to ensure that critical software meets specified requirements and functions; (2) if NASA has incorporated software risk management techniques into program; (3) whether standards are in place that will prescribe a disciplined, uniform approach to software development; and (4) if software support tools will help, as intended, to maximize efficiency in developing and maintaining the software. To meet the objectives, NASA proceeded: (1) reviewing and analyzing software development objectives and strategies contained in NASA conference publications; (2) reviewing and analyzing NASA, other government, and industry guidelines for establishing good software development practices; (3) reviewing and analyzing technical proposals and contracts; (4) reviewing and analyzing software management plans, risk management plans, and program requirements; (4) reviewing and analyzing reports prepared by NASA and contractor officials that identified key issues and challenges facing the program; (5) obtaining expert opinions on what constitutes appropriate independent V-and-V and software risk management activities; (6) interviewing program officials at NASA headquarters in Washington, DC; at the Space Station Program Office in Reston, Virginia; and at the three work package centers; Johnson in Houston, Texas; Marshall in Huntsville, Alabama; and Lewis in Cleveland, Ohio; and (7) interviewing contractor officials doing work for NASA at Johnson and Marshall.

The aim of this study was to construct a unique analytical in-house database (IHDB) for BSG discrimination based on whole-cell protein fingerprinting using MALDI-TOF MS, as well as to discover biomarkers from the MS peaks to generate a classification model for further differentiation using the ClinProTools software. Type strains of 12 species (included five subspecies) of the BSG were used to build a main spectrum profile (MSP) to create an IHDB under the optimized parameters. The BSG isolates obtained from partial recA gene sequencing were used for IHDB validation. A total of 84 (100%) isolates were correctly identified to the species level and had high score values (mean score: 2.52). However, the IHDB had ambiguous identification at the subspecies level of Bacillus amyloliquefaciens. After implementation of the classification models, the strains could be clearly differentiated. We have successfully developed a rapid, accurate and cost-effective platform for the species- and subspecies-level discrimination of BSG based on the implementation of the IHDB and coupled with ClinProTools, which can be employed as an alternative technology to DNA sequencing and applied for efficient quality control of the microbial agent.

    Hoppestad, Brian Scott

    2006-01-01

    The objective of this study was to determine prospective elements that should comprise a comprehensive and valid assessment of persons with severe disabilities for access to computers utilizing assistive technology (AT). Currently, there is a lack of guidelines regarding areas that permit a satisfactory measure of a person's need for AT devices to enable computer access, resulting in substandard services. A list of criteria for elements that should be incorporated into an instrument for determining AT for computer access was compiled from a literature review in the areas of neuroscience, rehabilitation, and education; and a Delphi study using an electronic survey form that was e-mailed to a panel of experts in the field of AT. Only those areas rated as essential to the assessment process ('very important' or 'important' by 80% of the respondents) were chosen as important criteria for an assessment instrument. The initial Delphi survey contained 22 categories (54 subcategories or elements) for incorporation into an assessment for computer access. The second round of the survey completed the Delphi process resulting in a consensus for inclusion of 39 of the elements in an assessment instrument. There are inherent obstacles to prescribing the proper AT device to assist disabled persons with computer access due to the complexity of his/her condition, and the multitude of technological devices available to aid persons in accomplishing diverse tasks. This study reveals the intricacy of the assessment process, especially in persons with severe disabilities associated with neurological conditions. An assessment instrument should be broad ranging, integrating both intrinsic and extrinsic factors, considering the multidimensional nature of AT prescription for computer access.

  20. The Utilization of Historical Data and Geospatial Technology Advances at the Jornada Experimental Range to Support Western America Ranching Culture

    Directory of Open Access Journals (Sweden)

    Kris Havstad

    2011-09-01

    Full Text Available By the early 1900s, concerns were expressed by ranchers, academicians, and federal scientists that widespread overgrazing and invasion of native grassland by woody shrubs were having severe negative impacts upon normal grazing practices in Western America. Ranchers wanted to reverse these trends and continue their way of life and were willing to work with scientists to achieve these goals. One response to this desire was establishment of the USDA Jornada Experimental Range (783 km2 in south central New Mexico by a Presidential Executive Order in 1912 for conducting rangeland investigations. This cooperative effort involved experiments to understand principles of proper management and the processes causing the woody shrub invasion as well as to identify treatments to eradicate shrubs. By the late 1940s, it was apparent that combining the historical ground-based data accumulated at Jornada Experimental Range with rapidly expanding post World War II technologies would yield a better understanding of the driving processes in these arid and semiarid ecosystems which could then lead to improved rangeland management practices. One specific technology was the use of aerial photography to interpret landscape resource conditions. The assembly and utilization of long-term historical aerial photography data sets has occurred over the last half century. More recently, Global Positioning System (GPS techniques have been used in a myriad of scientific endeavors including efforts to accurately locate historical and contemporary treatment plots and to track research animals including livestock and wildlife. As an incredible amount of both spatial and temporal data became available, Geographic Information Systems have been exploited to display various layers of data over the same locations. Subsequent analyses of these data layers have begun to yield new insights. The most recent technological development has been the deployment of Unmanned Aerial Vehicles (UAVs

    To evaluate and summarise the utility and impact of information communication technology (ICT) in enhancing student performance and the learning environment in pre-registration nursing. A systematic review of empirical research across a range of themes in ICT health-related education. Science Direct, Cinahl, AMED, MEDLINE, PubMed, ASSIA, OVID and OVID SP (2008-2014). Further date parameters were imposed by theme. Evidence was reviewed by narrative synthesis, adopting Caldwell's appraisal framework and CASP for qualitative methods. Selection and inclusion was grounded in the PICOS structure, with language requirements (English), and further parameters were guided by theme appropriateness. Fifty studies were selected for review across six domains: reusable learning objects, media, audience response systems, e-portfolios, computer-based assessment and faculty adoption of e-learning. Educational ICT was found to be non-inferior to traditional teaching, while offering benefits to teaching and learning efficiency. Where support is in place, ICT improves the learning environment for staff and students, but human and environmental barriers need to be addressed. This review illuminates more advantages for ICT in nurse training than previously. The key advantage of flexibility is supported, though with little evidence for effect on depth of learning.

  2. Effect of regulation on the rate of adoption of cost saving scale technology in the electric utility industry: a portfolio approach

    International Nuclear Information System (INIS)

    Scheraga, C.A.

    1984-01-01

    This study presents a new analytical framework for examining the relationship between regulation and the investment behavior of electric utilities. The particular kind of investment behavior considered is the adoption of new as well as innovative electrical generation technology. The technologies of interest are large scale coal and nuclear generation plants. The theoretical model used in this study differs from traditional approaches in its utilization of a behavioral framework of analysis. The responsiveness of utilities to the required rate of return demanded by stockholders is demonstrated using an augmented form of the standard Capital Asset Pricing Model. Regulation is viewed as affecting utility investment behavior through the effect of the actions of regulatory commissions on the required rate of return that utilities must earn on equity. The particular regulatory policies considered are modification of existing rate structure, automatic adjustment clauses, and required efficiency standards. These policies are of particular interest both because their effects have not been previously examined in detail, and because they are recommended for adoption in the Public Utility Regulatory Policies Act of 1978. It is demonstrated empirically that the above policies do affect the required rate of return for utilities and hence their innovative investment behavior

    This paper reports a duct heat collecting system installed in the ECOLO-HOUSE for snow countries. This system is an air heat collecting system of the outside air introducing type utilizing as a solar heat collector the single pitch roof often seen in snow countries. Outside air is introduced from below eaves into a heat collecting duct made by nailing plywoods onto rafters from the attic side to collect heat on the roof. Operating a sirocco fan connected to the induction duct located on the high-floor foundation sucks outside air from an air intake opening under the eaves into the heat collecting duct. Air which has absorbed heat on the roof and been warmed in the heat collecting duct by insolation goes into a heat collecting chamber. The air is sent into the high-floor foundation through the induction duct laid from the heat collecting chamber. Air is exchanged 8.7 times by the fan when it is operated all day continuously. Condensation in the fuel chamber floor and walls during the rainy season has disappeared, and so has odor at the same time. As a result of the humidity measurement, a location into which warm air is sent has difference in humidity as great as 15% from a location where no warm air is sent. 2 refs., 6 figs., 2 tabs.

    Full Text Available Basic problems in housing services and public utilities in the region are described: - economical - unavailability of loans; social - provocation of nervousness in the society; legal and political - rigid reliance on government; and technological - depreciation of existing networks. A number of measures to address these issues and create favorable conditions for the formation of business networks is suggested: creation of public-private management companies, reforming the legal framework and transition to the contractual relationship. A set of activities aimed at the development of business networks in this area was defined: creation a competitive business environment at the level of service providers and service-level houses in order to eliminate monopolies, attraction of large business networks, creation of business networks which will conduct service works to households, introduction of commercial initiatives and involvement of private operators. Thus, the concept of housing services and public utilities as a sector of the economy was formulated.

    Information and communication technology (ICT) tools are known to facilitate communication and processing of information and sharing of knowledge by electronic means. In Nigeria, the lack of adequate capacity on the use of ICT by health sector policymakers constitutes a major impediment to the uptake of research evidence into the policymaking process. The objective of this study was to improve the knowledge and capacity of policymakers to access and utilize policy relevant evidence. A modified "before and after" intervention study design was used in which outcomes were measured on the target participants both before the intervention is implemented and after. A 4-point likert scale according to the degree of adequacy; 1 = grossly inadequate, 4 = very adequate was employed. This study was conducted in Ebonyi State, south-eastern Nigeria and the participants were career health policy makers. A two-day intensive ICT training workshop was organized for policymakers who had 52 participants in attendance. Topics covered included: (i). intersectoral partnership/collaboration; (ii). Engaging ICT in evidence-informed policy making; use of ICT for evidence synthesis; (iv) capacity development on the use of computer, internet and other ICT. The pre-workshop mean of knowledge and capacity for use of ICT ranged from 2.19-3.05, while the post-workshop mean ranged from 2.67-3.67 on 4-point scale. The percentage increase in mean of knowledge and capacity at the end of the workshop ranged from 8.3%-39.1%. Findings of this study suggest that policymakers' ICT competence relevant to evidence-informed policymaking can be enhanced through training workshop.

    2005-05-01

    Full Text Available Abstract Background Genomic approaches in large animal models (canine, ovine etc are challenging due to insufficient genomic information for these species and the lack of availability of corresponding microarray platforms. To address this problem, we speculated that conserved interspecies genetic sequences can be experimentally detected by cross-species hybridization. The Affymetrix platform probe redundancy offers flexibility in selecting individual probes with high sequence similarities between related species for gene expression analysis. Results Gene expression profiles of 40 canine samples were generated using the human HG-U133A GeneChip (U133A. Due to interspecies genetic differences, only 14 ± 2% of canine transcripts were detected by U133A probe sets whereas profiling of 40 human samples detected 49 ± 6% of human transcripts. However, when these probe sets were deconstructed into individual probes and examined performance of each probe, we found that 47% of human probes were able to find their targets in canine tissues and generate a detectable hybridization signal. Therefore, we restricted gene expression analysis to these probes and observed the 60% increase in the number of identified canine transcripts. These results were validated by comparison of transcripts identified by our restricted analysis of cross-species hybridization with transcripts identified by hybridization of total lung canine mRNA to new Affymetrix Canine GeneChip®. Conclusion The experimental identification and restriction of gene expression analysis to probes with detectable hybridization signal drastically increases transcript detection of canine-human hybridization suggesting the possibility of broad utilization of cross-hybridizations of related species using GeneChip technology.

  16. House Demolitions

    Directory of Open Access Journals (Sweden)

    Mordechai Kremnitzer

    2015-05-01

    Full Text Available This article discusses the nature of “house demolitions” as used by the State of Israel in the West Bank and East Jerusalem. In our opinion, and in contrast to the view of Israel’s Supreme Court, such demolition orders constitute a penal sanction. As a penal sanction, we argue that this measure violates the basic principles of criminal liability. Even if this conclusion is not accepted, it will be argued that making innocent people homeless is an illegal collective measure. Even if assuming arguendo that it is not an illegal collective measure, it violates the basic principle of personal responsibility. The general conclusion of the article is that the examination of the nature of sanctions should go beyond the labels that are attached to them. Labeling sanctions as either penal or civil may not always reflect its true nature, and labels are sometimes deliberately used or rather misused in order to escape from the requirements stemming from the true essence of a sanction.

    2004-11-01

    Until recently, the increase in electricity demand and peak power demand has been met by expansion of the electricity production. Today, due to the deregulation of the electricity market, the production capacity is decreasing. Therefore, there is a national interest in finding solutions to peak problems also on the demand side. In the studies described here (Study 1 and 2) ten households in electrically heated houses were examined. In 1999 the utility equipped their customers with a remote metering system (CustCom) that has an in-built load control component. In Study 1, the load pattern of ten households was examined by using energy diaries combined with frequent meter readings (every five minutes) of the load demand for heating, hot water service and domestic electricity use. Household members kept energy diaries over a four-day period in January 2004, noting time, activities and the use of household appliances that run on electricity. The analysis showed that the use of heat-producing household appliances, e.g. sauna, washing machine and dryer, appliances used for cooking, dishwasher and extra electric heaters, contribute to the household's highest peaks. Turning on the sauna and at the same time using the shower equates to a peak load of 7-9 kW. This, in addition to the use of electricity for heating and lighting along alongside electricity use for refrigerators and freezers, results in some households reaching their main fuse level (roughly 13,8 kW for a main fuse of 20 A). This means that the domestic use of electricity makes up a considerable part of the highest peak loads in a household, but the highest peaks occur together with the use of electricity for heating and hot water. In the second study, Study 2, the households participated in a load control experiment, in which the utility was able to turn on and switch off the heating and hot water systems remotely, using the CustCom system. Heating and water heaters were switched off for periods of 1

    2018-03-01

    With the gradual maturity of the real estate market in China, urban housing prices are also better able to reflect changes in market demand and the commodity property of commercial housing has become more and more obvious. Many scholars in our country have made a lot of research on the factors that affect the price of commercial housing in the city and the number of related research papers increased rapidly. These scholars’ research results provide valuable wealth to solve the problem of urban housing price changes in our country. However, due to the huge amount of literature, the vast amount of information is submerged in the library and cannot be fully utilized. Text mining technology has been widely concerned and developed in the field of Humanities and Social Sciences in recent years. But through the text mining technology to obtain the influence factors on the price of urban commercial housing is still relatively rare. In this paper, the research results of the existing scholars were excavated by text mining algorithm based on support vector machine in order to further make full use of the current research results and to provide a reference for stabilizing housing prices.

    2014-01-01

    Background Alcohol misuse remains a major risk factor for contracting sexually transmitted diseases (STDs) not typically addressed in STD clinic settings. Information and communication technology (ICT) can offer new avenues to deliver evidence-based screening and treatment for problematic drinking, however, few data exists regarding the utilization of ICT among STD clinic attendees with coexisting drinking problems. The objectives of this study are to identify STD clinics attendees with hazardous drinking, to examine socio-demographic factors associated with ICT use, and to explore individuals’ interests in engaging in ICT-based health interventions. Methods Cross-sectional questionnaires examining alcohol consumption and ICT use were administered to 396 persons attending two non-urban STD clinics. Descriptive statistics for ICT use were calculated for both hazardous drinkers and the entire sample. Multivariable logistic regression models among hazardous drinkers identified factors significantly associated with use of each kind of ICT. Results The mean age of the 396 participants was 25 years, 66% were females and 60% were African-Americans. One third of the sample met the criteria of hazardous drinking. ICT use in hazardous drinkers included 94% reporting having internet access at least monthly, 82% reporting having an email account, 85% reporting currently owning a cell phone, and 91% reporting use of any cell phone application. More than two thirds (73%) of hazardous drinkers were willing to play health-related video games during clinic waiting time, slightly higher than the entire sample (69%). Multivariable analyses indicated that younger age were significantly related to monthly internet use, and multifunction cell phone use, while being males and younger age were significantly associated with monthly video game playing. Conclusions Our study demonstrates commonality of ICT use among STD clinic attendees with hazardous drinking, indicating the viability of

    The combination of distributed energy resources (DER) and retail tariff structures to provide benefits to both utility consumers and the utilities is poorly understood. To improve understanding, an Integrated Energy System Model (IESM) is being developed to simulate the physical and economic aspects of DER technologies, the buildings where they reside, and feeders servicing them. The IESM was used to simulate 20 houses with home energy management systems on a single feeder under a time of use tariff to estimate economic and physical impacts on both the households and the distribution utilities. HEMS reduce consumers’ electric bills by precooling houses in the hours before peak electricity pricing. Household savings are greater than the reduction utility net revenue indicating that HEMS can provide a societal benefit providing tariffs are structured so that utilities remain solvent. Utilization of HEMS reduce peak loads during high price hours but shifts it to hours with off-peak and shoulder prices and resulting in a higher peak load.

    2013-02-01

    Homeless emerging adults need the safety and stability of housing programs if they are to avoid the elements and victimization of the streets, however, barriers to obtaining housing are numerous. This study identified factors associated with perspectives of housing services among 29 homeless emerging adults (ages 18-23 years) through one-on-one interviews. Data were gathered and analyzed using grounded theory methodology for qualitative information. Major themes of peer support and positive personal and programmatic interactions in the context of emerging adult development were noted as important factors in housing service utilization. These major themes should be taken into consideration for current housing programs, due to homeless emerging adults' oscillation between their desire for formal support and personal independence. Greater emphasis on services that do not require long term commitments and are more flexible in addressing specific barriers to housing for homeless emerging adults may increase use.

  16. 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

    Energy Technology Data Exchange (ETDEWEB)

    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.

    The new guidelines for science education emphasize the need to introduce computers and digital technologies as a means of enabling visualization and data collection and analysis. This requires science teachers to bring advanced technologies into the classroom and use them wisely. Hence, the goal of this study was twofold: to examine the application of web-based technologies in science teacher preparation courses and to examine pre-service teachers' perceptions of "cloud pedagogy"—an instructional framework that applies technologies for the promotion of social constructivist learning. The study included university teachers ( N = 48) and pre-service science teachers ( N = 73). Data were collected from an online survey, written reflections, and interviews. The findings indicated that university teachers use technologies mainly for information management and the distribution of learning materials and less for applying social constructivist pedagogy. University teachers expect their students (i.e., pre-service science teachers) to use digital tools in their future classroom to a greater extent than they themselves do. The findings also indicated that the "cloud pedagogy" was perceived as an appropriate instructional framework for contemporary science education. The application of the cloud pedagogy fosters four attributes: the ability to adapt to frequent changes and uncertain situations, the ability to collaborate and communicate in decentralized environments, the ability to generate data and manage it, and the ability to explore new venous.

    In Denmark and in many countries around the world, housing markets are of considerable importance for households and policy-makers alike. As the boom and bust in the US and Danish housing market so aptly demonstrated, disruptions in the housing market potentially have wide-ranging consequences...... for individual households and for the aggregate economy. Housing is important because we all have to live somewhere, but also because it serves as a considerable source of both wealth and debt. As such, housing market policy can not only create vast benefits for many, but can also have substantial negative...... impacts for all, and should therefore be a topic of major interest for economists and policy makers alike.

    Van Mierlo, B.; Sprengers, M.

    1995-12-01

    In a new housing estate in Amsterdam in 1995 the regional energy utility (EBA) has integrated a photovoltaic (PV) system (250 kWp) into 63 houses out of 245 houses. The parts of these owner-occupied houses with PV panels are not owned by the occupants. In order to determine which are the motives to buy solar houses and in order to analyze changes in their attitudes questionnaires were sent to potential occupants twice. First to the people who registered for the new housing project (subscribers), and second to the people who bought one of the 245 houses either with or without PV (buyers). The overall conclusion is that PV does not play an important role in the decision making process when buying a new house. It is recommended to study differences in PV preferences and opinions a few years after the buyers have moved to their new houses. 10 figs., 17 tabs., 9 refs., 3 appendices

    2012-07-01

    Full Text Available Liberalization of electricity markets, governmental policies for renewable electricity and technology development are transforming national electricity industries. However, there are considerable national differences in how these industries have changed and which businesses have been developed. We propose a typology for comparing changes in electricity industry based on the changes in the actors and technologies. Wind power and solar photovoltaic are used here as technology examples. A qualitative analysis of the changes in electricity industries in four EU member states is presented. Based on the preliminary findings, we conclude that if the industry consists of many, small firms with relatively loose ties with the government the industry is more likely to change than if it consists of few large firms with strong relations with the government.

    2018-03-01

    Near Zero Energy House (NZEH) is a housing building that provides energy efficiency by using renewable energy technologies and passive house design. Currently, the costs for NZEH are quite expensive due to the high costs of the equipment and materials for solar panel, insulation, fenestration and other renewable energy technology. Therefore, a study to obtain the optimum design of a NZEH is necessary. The aim of the optimum design is achieving an economical life cycle cost performance of the NZEH. One of the optimization methods that could be utilized is Genetic Algorithm. It provides the method to obtain the optimum design based on the combinations of NZEH variable designs. This paper discusses the study to identify the optimum design of a NZEH that provides an optimum life cycle cost performance using Genetic Algorithm. In this study, an experiment through extensive design simulations of a one-level house model was conducted. As a result, the study provide the optimum design from combinations of NZEH variable designs, which are building orientation, window to wall ratio, and glazing types that would maximize the energy generated by photovoltaic panel. Hence, the design would support an optimum life cycle cost performance of the house.

  16. Current issues on the production and utilization of medium-calorific solid recovered fuel: a case study on SRF for the HOTDISC technology.

    Science.gov (United States)

    Pomberger, Roland; Klampfl-Pernold, Hannes; Abl, Christian

    2012-04-01

    The HOTDISC technology allows the use of Solid Recovered Fuel (SRF) of a coarse grain size in cement rotary kilns. A suitable medium-calorific SRF is produced by mechanical treatment of mixed municipal and commercial waste that was previously used in fluidized bed incineration systems. Through a modification of the production process the quality of the SRF could be improved and its energetic utilization within a cement kiln with an integrated HOTDISC technology was realized. In course of a material flow analysis changes in quality and mass due to planned process changes were simulated on a theoretical basis. Due to a good agreement of the mass and quality prediction with the real data of the material flow analysis conducted after the system implementation it can be stated that by simulation beforehand the security in planning increases while the economic risk can be significantly reduced. Both the material flow analysis as well as practical operational experience confirms that the industrially produced HOTDISC SRF is applicable and can be produced from mixed municipal and commercial solid waste. An improvement in quality of the produced HOTDISC SRF can be shown by positive changes of essential parameters. From a waste management perspective the production and energetic utilization of HOTDISC SRF is reasonable by all means. This is shown by the conduction of an energy and CO₂-balance. A growing international importance of the HOTDISC technology and the increased use of medium-calorific SRF are expected.

    Epidemiologic study. To compare the utilization of anterior cervical discectomy and fusion (ACDF) versus cervical disc arthroplasty (CDA) in terms of patient and hospital characteristics during the 3 years after Food and Drug Administration (FDA) approval of CDA devices in 2007. There was a surge in CDA adoption in the 3 years prior to FDA approval of CDA devices in 2007. However, utilization trends of CDA versus ACDF since the FDA approval are unknown. The Nationwide Inpatient Sample database was used to identify CDA and ACDF procedures performed in the United States in the 3 years after FDA approval of CDA devices (2008-2010). The frequencies of CDA and ACDF were estimated, stratified by patient and hospital characteristics. Average length of hospital stay and total charges and costs were estimated. Multivariable analysis was performed to identify patient and hospital characteristics associated with CDA utilization. In the 3 years after FDA approval of cervical disc devices, population-adjusted growth rates for CDA and ACDF were 4.9% and 11.8%, respectively (P = 0.6977). Female, African American and Medicaid patients were less likely to receive CDA. CDA was less likely to be performed in patients with cervical spondylotic changes and more likely to be performed in younger and healthier patients. CDA was less likely to be performed in the Midwestern United States or in public hospitals. The prevalence of CDA increased in the 3 years after FDA approval with a growth rate that is approximately twice than that for ACDF. Although there seems to be CDA adoption, CDA growth seemed to have reached a plateau and ACDF still remained the dominant surgical strategy for cervical disc disease. Possible regional, racial, and sex disparities in CDA utilization and a more strict approach in the selection of CDA over traditional ACDF may have impeded rapid adoption of CDA. 3.

  18. Household energy and climate mitigation policies: Investigating energy practices in the housing sector

    Schaffrin, André; Reibling, Nadine

    2015-01-01

    One central aim of climate change mitigation in the European Union is to reduce energy consumption in the housing sector. In order to ensure effectiveness of policies targeting household energy conservation, it is important to investigate existing energy practices of different social groups. This article describes and explains energy practices in three leading states in environmental politics, technological innovation, and support for renewable energy production: Denmark, Austria, and the United Kingdom. Based on a longitudinal analysis of housing utility costs from the European Community Statistics on Income and Living Conditions we show that income plays a central role in households' energy practices. While high-income households have higher overall energy consumption, low-income groups spend a larger share of their income on utility costs. The variation of energy consumption across income groups is related to household characteristics, characteristics of the dwellings, and cross-national differences in the housing sector. - Highlights: • We explain energy practices in Denmark, Austria, and the United Kingdom. • We show that income plays a central role in households’ energy practices. • High-income households have higher overall energy consumption. • Low-income groups spend a larger share of their income on utility costs. • Consumption depends on the household, dwelling and the housing sector

    The study determines the cost-utility of a unilateral electronic knee prosthesis (C-leg) compared to mechanical alternatives in trans-femoral amputees. For each type of prosthesis, 50 patients, treated in a major Italian centre, were enrolled. Quality adjusted life years (QALYs) were estimated from responses to EuroQol (EQ-5D). Healthcare and social costs were assessed for the estimated life cycle of the technologies (5 years). C-leg was associated with 0.09 more QALYs per patient per year (P = 0.007). For the 5-year period, the incremental cost-utility ratio of C-leg resulted in euro 35,971 per QALY from the healthcare system perspective. If non-healthcare costs and productivity losses are included, the two groups to have similar costs (euro 66,669 vs euro 66,927).

    1990-09-01

    COMPLEAT takes its name, as an acronym, from Community-Oriented Model for Planning Least-Cost Energy Alternatives and Technologies. It is an electric utility planning model designed for use principally by publicly owned electric utilities and agencies serving such utilities. As a model, COMPLEAT is significantly more full-featured and complex than called out in APPA's original plan and proposal to DOE. The additional complexity grew out of a series of discussions early in the development schedule, in which it became clear to APPA staff and advisors that the simplicity characterizing the original plan, while highly desirable in terms of utility applications, was not achievable if practical utility problems were to be addressed. The project teams settled on Energy 20/20, an existing model developed by Dr. George Backus of Policy Assessment Associates, as the best candidate for the kinds of modifications and extensions that would be required. The remainder of the project effort was devoted to designing specific input data files, output files, and user screens and to writing and testing the compute programs that would properly implement the desired features around Energy 20/20 as a core program. This report presents in outline form, the features and user interface of COMPLEAT.

    It is widely recognised that the quantity and sustainability of new homes in the UK need to increase. However, it is important that sustainable housing is regarded holistically, and not merely in environmental terms, and incorporates elements that enhance the quality of life, health and well-being of its users. This paper focuses on the "soft" features of sustainable housing, that is, the non-technological components of sustainable housing and neighbourhood design that can impact occupants' health and well-being. Aims of the study are to ascertain the relative level of importance that key housing stakeholders attach to these features and to investigate whether the opinions of housing users and housing providers are aligned with regards to their importance. An online survey was carried out to gauge the level of importance that the key stakeholders, such as housing users, local authorities, housing associations, and developers (n = 235), attach to these features. Results revealed that while suitable indoor space was the feature regarded as most important by all stakeholders, there were also a number of disparities in opinion between housing users and housing providers (and among the different types of providers). This implies a scope for initiatives to achieve a better alignment between housing users and providers.

    We discuss a new EcoDesign method, with a goal of improving the economy, and its application to a sustainable networked society. The new EcoDesign method differs from conventional EcoDesign in three respects: it utilizes a top-down approach, project-style research, and fact-finding and benchmarking. We systematize EcoDesign for a networked society from the viewpoint of technology and divide it into four components. Feasibility studies of the individual components reveal that if we promote ICT diffusion with EcoDesign in mind, we can suppress CO2 emissions and move towards a more sustainable society. (orig.)

    An essentially new scheme of the electronuclear method - relativistic nuclear technology (RNT) - is considered. This is based on the use of the neutron spectrum forming in the deep subcritical active core, much harder than created in chain fission process. It is shown that an application of RNT for utilization of the radioactive nuclear wastes and energy production seems to be very promising. The results of the first experiments carried out at JINR demonstrate the validity of basic principles of RNT. In particular, these point to the essential (twofold) growth of beam power gain in massive (315 kg) uranium target irradiated with deuterons with increasing energy from 1 to 4 GeV

    2014-06-01

    Full Text Available One major factor that account for housing market crises in developing countries is the seeming disconnect between housing policies and housing markets in these countries. This paper examines the links between housing policy and urban housing market dynamics in context of developing world drawing from the housing market situation in selected urban centres in Ondo state of Nigeria. The data utilized were derived from the study of housing situations in the selected urban centres. Thus 180 questionnaires were administered on selected household heads and key officials of major agencies and organizations including government departments involved in housing provision and development in the state. The data collected were analyzed using simple descriptive analysis where appropriate. The study revealed that housing policies introduced over the years have had little impact on housing production and by implication urban housing market in the study cities. The study also revealed a disconnect between these policies and housing provision and trends in terms of quality, quantity, affordability and accessibility to housing. The paper argued that these were so because institutions connected to efficient functioning of these policies were inefficient, ineffective and sometime over ambitious and so more often than not, set goals were not met. The study concluded by suggesting more commitment on the part of Federal and Ondo state governments to ensure these policies dovetail to housing consumers.

  1. A market systems analysis of the U.S. Sport Utility Vehicle market considering frontal crash safety technology and policy.

    2013-01-01

    Active safety features and adjustments to the New Car Assessment Program (NCAP) consumer-information crash tests have the potential to decrease the number of serious traffic injuries each year, according to previous studies. However, literature suggests that risk reductions, particularly in the automotive market, are often accompanied by adjusted consumer risk tolerance, and so these potential safety benefits may not be fully realized due to changes in consumer purchasing or driving behavior. This article approaches safety in the new vehicle market, particularly in the Sport Utility Vehicle and Crossover Utility Vehicle segments, from a market systems perspective. Crash statistics and simulations are used to predict the effects of design and policy changes on occupant crash safety, and discrete choice experiments are conducted to estimate the values consumers place on vehicle attributes. These models are combined in a market simulation that forecasts how consumers respond to the available vehicle alternatives, resulting in predictions of the market share of each vehicle and how the change in fleet mixture influences societal outcomes including injuries, fuel consumption, and firm profits. The model is tested for a scenario where active safety features are implemented across the new vehicle fleet and a scenario where the U.S. frontal NCAP test speed is modified. While results exhibit evidence of consumer risk adjustment, they support adding active safety features and lowering the NCAP frontal test speed, as these changes are predicted to improve the welfare of both firms and society.

    Specific protein domains known as protein transduction domains (PTDs) can permeate cell membranes and deliver proteins or bioactive materials into living cells. Various approaches have been applied for improving their transduction efficacy. It is, therefore, crucial to clarify the entry mechanisms and to identify the rate-limiting steps. Because of technical limitations for imaging PTD behavior on cells with conventional fluorescent-dyes, how PTDs enter the cells has been a topic of much debate. Utilizing quantum dots (QDs), we recently tracked the behavior of PTD that was derived from HIV-1 Tat (TatP) in living cells at the single-molecule level with 7-nm special precision. In this review article, we initially summarize the controversy on TatP entry mechanisms; thereafter, we will focus on our recent findings on single-TatP-QD tracking (SQT), to identify the major sequential steps of intracellular delivery in living cells and to discuss how SQT can easily provide direct information on TatP entry mechanisms. As a primer for SQT study, we also discuss the latest findings on single particle tracking of various molecules on the plasma membrane. Finally, we discuss the problems of QDs and the challenges for the future in utilizing currently available QD probes for SQT. In conclusion, direct identification of the rate-limiting steps of PTD entry with SQT should dramatically improve the methods for enhancing transduction efficiency.

    Mineral deficiencies, especially of iron, zinc, and calcium, respectively, negatively affect human health and may lead to conditions such as iron deficiency anemia, rickets, osteoporosis, and diseases of the immune system. Cereal grains and legumes are of global importance in nutrition of monogastrics (humans and the respective domestic animals) and provide high amounts of several minerals, e.g., iron, zinc, and calcium. Nevertheless, their bioavailability is low. Plants contain phytates, the salts of phytic acid, chemically known as inositol-hexakisphosphate, which interact with several minerals and proteins. However, phytate may be hydrolysed by phytase. This enzyme is naturally present in plants and also widely distributed in microorganisms. Several food processing methods have been reported to enhance phytate hydrolysis, due to the activation of endogenous phytase activity or via the enzyme produced by microbes. In recent years, fermentation for food and feed improvement and preservation, respectively, has gained increasing interest as a promising method to degrade phytate and enhance mineral utilization in monogastrics. Indeed, several in vitro as well as in vivo studies confirm a positive effect on the utilization of minerals, such as P, Ca, Fe and Zn, using sourdough fermentation for baking or fermentation of legumes, mainly soybeans. This review summarizes the current knowledge regarding the potential of fermentation to enhance macro and trace element bioavailability in monogastric species. Copyright © 2016 Elsevier GmbH.

    The value of routine postoperative visits after general surgery remains unclear. The objective of this study was to evaluate the utility of routine postoperative visits after appendectomy and cholecystectomy and to determine access to mobile technology as an alternative platform for follow-up. Retrospective review of 219 appendectomies and 200 cholecystectomies performed at a safety net hospital. One patient underwent both surgeries. Patient demographics, duration of clinic visit, and need for additional imaging, tests or readmissions were recorded. Access to mobile technology was surveyed by a validated questionnaire. Of 418 patients, 84% percent completed a postoperative visit. At follow-up, 58 patients (14%) required 70 interventions, including staple removal (16, 23%), suture removal (4, 6%), drain removal (8, 11%), additional follow-up (20, 28%), medication action (16, 21%), additional imaging (3, 4%), and readmission (1, 1%). Occupational paperwork (62) and nonsurgical clinic referrals (28) were also performed. Average check-in to check-out time was 100 ± 54 min per patient. One intervention was performed for every 7.8 h of time in the clinic. Additionally, 88% of the surveyed population reported access to cell phone technology, and 69% of patients mobile technology, which is pervasive in our population. Copyright © 2014 Elsevier Inc.

    Energy Technology Data Exchange (ETDEWEB)

    1977-01-01

    This report presents an initial evaluation of the major health and environmental issues associated with increased coal use in the six midwestern states of Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. Using an integrated assessment approach, the evaluation proceeds from a base-line scenario of energy demand and facility siting for 1975-2020. Emphasis is placed on impacts from coal extraction, land reclamation, coal combustion for electrical generation, and coal gasification. The range of potential impacts and constraints is illustrated by a second scenario that represents an expected upper limit for coal utilization in Illinois. The following are among the more significant issues identified and evaluated in this study: If environmental and related issues can be resolved, coal will continue to be a major source of energy for the Midwest; existing sulfur emission constraints will increase use of western coal; the resource requirements and environmental impacts of coal utilization will require major significant environmental and economic tradeoffs in site selection; short-term (24-hr) ambient standards for sulfur dioxide will limit the sizes of coal facilities or require advanced control technologies; an impact on public health may result from long-range transport of airborne sulfur emissions from coal facilities in the Midwest; inadequately controlled effluents from coal gasification may cause violations of water-quality standards; the major ecological effects of coal extraction are from pre-mining and post-reclamation land use; and sulfur dioxide is the major potential contributor to effects on vegetation of atmospheric emissions from coal facilities.

    Mercury (Hg) control technologies were evaluated at Minnkota Power Cooperative's Milton R. Young (MRY) Station Unit 2, a 450-MW lignite-fired cyclone unit near Center, North Dakota, and TXU Energy's Monticello Steam Electric Station (MoSES) Unit 3, a 793-MW lignite--Powder River Basin (PRB) subbituminous coal-fired unit near Mt. Pleasant, Texas. A cold-side electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) scrubber are used at MRY and MoSES for controlling particulate and sulfur dioxide (SO{sub 2}) emissions, respectively. Several approaches for significantly and cost-effectively oxidizing elemental mercury (Hg{sup 0}) in lignite combustion flue gases, followed by capture in an ESP and/or FGD scrubber were evaluated. The project team involved in performing the technical aspects of the project included Babcock & Wilcox, the Energy & Environmental Research Center (EERC), the Electric Power Research Institute, and URS Corporation. Calcium bromide (CaBr{sub 2}), calcium chloride (CaCl{sub 2}), magnesium chloride (MgCl{sub 2}), and a proprietary sorbent enhancement additive (SEA), hereafter referred to as SEA2, were added to the lignite feeds to enhance Hg capture in the ESP and/or wet FGD. In addition, powdered activated carbon (PAC) was injected upstream of the ESP at MRY Unit 2. The work involved establishing Hg concentrations and removal rates across existing ESP and FGD units, determining costs associated with a given Hg removal efficiency, quantifying the balance-of-plant impacts of the control technologies, and facilitating technology commercialization. The primary project goal was to achieve ESP-FGD Hg removal efficiencies of {ge}55% at MRY and MoSES for about a month.

    Counterfeiting of currency and identity documents, death threats, illegitimate business transactions, and terrorist-related activities are some examples of the types of crimes that often involve documents produced from printers and copiers. Although standard protocol typically requires a questioned document (QD) examination prior to latent print (LP) processing, occasionally, items of evidence may be submitted for a QD examination following the application of a series chemicals utilized in the development of latent fingerprints. In such cases, the forensic examiner must take into account any previous treatments prior to initiating an examination on documents produced with a printer or copier. This study was devised to examine the effects of a latent print development technique [ninhydrin, physical developer, and a bleach enhancer] on the physical and chemical examination of documents produced from copiers and printers.

    The essence of methods for soil decontamination based on electrokinetic processes is that, in the field of constant current, contaminated particles-ions, depending on their charge mark, move to anode or cathode sides. If such a field is created in the soil containing ions of radionuclides or heavy metals, those ions-contaminants will begin to concentrated in the cathode or anode zone, i.e. soil decontamination with ion electric migration process takes place. During the recent tour years specialists from Mos RPA (Moscow Research-and-Production Association) Radon (Russia) have been conducting an extensive investigation on the utilization of electrokinetic processes for decontamination of soils from radionuclides and heavy metals

    ABSTRACT The clinical utility of microarray technologies when used in the context of prenatal diagnosis lies in the technology's ability to detect submicroscopic copy number changes that are associated with clinically significant outcomes. We have carried out a systematic review of the literature to calculate the utility of prenatal microarrays in the presence of a normal conventional karyotype. Amongst 12 362 cases in studies that recruited cases from all prenatal ascertainment groups, 295/12 362 (2.4%) overall were reported to have copy number changes with associated clinical significance (pCNC), 201/3090 (6.5%) when ascertained with an abnormal ultrasound, 50/5108 (1.0%) when ascertained because of increased maternal age and 44/4164 (1.1%) for all other ascertainment groups (e.g. parental anxiety and abnormal serum screening result). When additional prenatal microarray studies are included in which ascertainment was restricted to fetuses with abnormal ultrasound scans, 262/3730 (7.0%) were reported to have pCNCs. © 2013 The Authors.

    Powerspan has conducted pilot scale testing of a multi-pollutant control technology at FirstEnergy's Burger Power Plant under a cooperative agreement with the U.S. Department of Energy. The technology, Electro-Catalytic Oxidation (ECO), simultaneously removes sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}), fine particulate matter (PM{sub 2.5}) and mercury (Hg) from the flue gas of coal-fired power plants. Powerspan's ECO{reg_sign} pilot test program focused on optimization of Hg removal in a 1-MWe slipstream pilot while maintaining greater than 90% removal of NO{sub x} and 98% removal of SO{sub 2}. This Final Technical Report discusses pilot operations, installation and maintenance of the Hg SCEMS instrumentation, and performance results including component and overall removal efficiencies of SO{sub 2}, NO{sub x}, PM and Hg from the flue gas and removal of captured Hg from the co-product fertilizer stream.

  15. Estimating the Value of Utility-Scale Solar Technologies in California Under a 40% Renewable Portfolio Standard

    Concentrating solar power with thermal energy storage (CSP-TES) is a unique source of solar energy in that its output can be shifted over time. The ability of CSP-TES to be a flexible source of generation may be particularly valuable in regions with high overall penetration of solar energy, such as the state of California. California's Renewable Portfolio Standard (RPS) requires the state to increase generation from eligible renewable energy resources to reach 33% of retail electricity sales by 2020. Beyond 2020, California targets a further reduction in greenhouse gas emissions. To help reach this goal, current California governor Jerry Brown has stated that a higher 40% RPS might be reachable in the near term. The levelized cost of energy is generally emphasized when assessing the economic viability of renewable energy systems implemented to achieve the RPS. However, the operational and capacity benefits of such systems are often ignored, which can lead to incorrect economic comparisons between CSP-TES and variable renewable generation technologies such as solar photovoltaics (PV). Here we evaluate a 40% RPS scenario in a California grid model with PV or CSP-TES providing the last 1% of RPS energy. We compare the technical and economic implications of integrating either solar technology under several sensitivities, finding that the ability to displace new conventional thermal generation capacity may be the largest source of value of CSP-TES compared to PV at high solar penetrations.

    The coal cartridge system (CCS) is a series of the total system, in which coal is processed centrally at a supply base for each unit of consumer areas, supplied as pulverized coal in bulk units, and coal ash after combustion is recovered and treated. The system is expected of advantages resulted from the centralized production, elimination of handling troubles, and cleanliness. Following a small scale demonstration test, a large demonstration test for practically usable scale has begun in 1990, and completed in fiscal 1995. This paper introduces the CCS and reports the result of the test. In the large demonstration test, a supply station (with manufacturing capability of 200,000 tons a year) was installed in the Aichi refinery of Idemitsu Kosan Co., Ltd., and systematization on quality design and system technologies has been carried out. Long-term continuous operation for five years was achieved (operation time of the supply facilities was about 19,000 hours) without a failure and accident, to which every elemental technology was evaluated highly, and convenience and reliability of the system was verified. 13 figs., 3 tabs.

    The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and US Department of Energy (DOE) is the development of the GE 7H and 9H combined cycle power systems. The major effort will be expended on detail design. Validation of critical components and technologies will be performed including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE`s request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown. This report summarizes work accomplished in 4Q97.

    Full Text Available Two themes are evident in housing research in Ghana. One involves the study of how to increase the number of dwellings to correct the overall housing deficit, and the other focuses on how to improve housing for slum dwellers. Between these two extremes, there is relatively little research on why the existing buildings are poorly maintained. This paper is based on a review of existing studies on inadequate housing. It synthesises the evidence on the possible reasons for this neglect, makes a case for better maintenance and analyses possible ways of reversing the problem of inadequate housing.

    building-components industry, energy or waste networks and providers, and planning regulations. The professional partners for the projects, such as housing associations and engineers, are equally affected by the institutional context, but their position is different from that of residents. They may for example be more anchored in governmental or professional regulations. To structure this dynamic, the research distinguishes three interrelated aspects: • ACTORS / involved in the (realisation of projects: social practices of residents and their professional partners in co-creation. • CONTEXT / the structural forces surrounding the projects, specifically the macroinstitutional regimes. This also includes culturally determined interpretations of sustainability, technology, participation, societal roles, sharing, and so on. • TECHNOSPHERE / specifically building technology and utilities, focussing on energyrelated design and engineering of the co-housing projects. The thesis is primarily based on qualitative methods, as it found that reliable quantitative data are as yet unavailable. Looking for effective low-impact energysolution in co-housing, quantitative data remain however necessary and this thesis elaborates on pitfalls and possibilities for their accumulation. Empirical material from Dutch case-studies form the core of the research. Examples were also taken from countries where the re-emergence of co-housing is most visible and articulate: Belgium, France, Germany, the UK and Switzerland. Co-housing continues to develop and gain experiences with competences, such as communication skills and the ability to work cross-disciplinarily. The building industry and engineering professions increasingly call for such capabilities, but resident-led urban development have not yet entered the urbanism and engineering curricula. Therefore, opportunities should be provided for future professionals not only to acquire such capabilities but also to address fundamental questions

    Full Text Available Subject: smart house maintenance requires taking into account a number of factors: resource-saving, reduction of operational expenditures, safety enhancement, providing comfortable working and leisure conditions. Automation of the corresponding engineering systems of illumination, climate control, security as well as communication systems and networks via utilization of contemporary technologies (e.g., IoT - Internet of Things poses a significant challenge related to storage and processing of the overwhelmingly massive volume of data whose utilization extent is extremely low nowadays. Since a building’s lifespan is large enough and exceeds the lifespan of codes and standards that take into account the requirements of safety, comfort, energy saving, etc., it is necessary to consider management aspects in the context of rational use of large data at the stage of information modeling. Research objectives: increase the efficiency of managing the subsystems of smart buildings hardware on the basis of a web-based information system that has a flexible multi-level architecture with several control loops and an adaptation model. Materials and methods: since a smart house belongs to man-machine systems, the cybernetic approach is considered as the basic method for design and research of information management system. Instrumental research methods are represented by set-theoretical modelling, automata theory and architectural principles of organization of information management systems. Results: a flexible architecture of information system for management of smart house hardware subsystems has been synthesized. This architecture encompasses several levels: client level, application level and data level as well as three layers: presentation level, actuating device layer and analytics layer. The problem of growing volumes of information processed by realtime message controller is attended by employment of sensors and actuating mechanisms with configurable

    Skeletal deformity in the fronto-orbital region resulting from various problems can have significant aesthetic concerns. Restoring an aesthetically acceptable appearance relies most importantly on the restoration of a precise skeletal contour. Current surgical options for depression deformities or partial-thickness defects range from extensive corrective osteotomies to less complicated methods of onlay grafting with autogenous or alloplastic materials. Both methods have difficulties in providing a symmetric and smooth contour for predictable and reliable cosmetic results. Alloplastic implants provide another effective alternative and the success of the skeletal contouring correlates directly with the accuracy of the implant sculpture. Prefabricated methylmethacrylate implants, with the aid of modeling clay, computer imaging, and modern rapid-prototyping technologies, fits the depression deformity well and balances the skeletal contour. It provides plastic surgeons greater precision in customizing the implant, which ensures better predictability and reliability of cosmetic outcomes.

    The goal of the Thermochron Mission, an embedded strand of the NASA Goddard Space Flight Center History of Winter (HOW) Program, is to engage participants actively in research methods while focusing on the observation and analysis of changes in ambient temperature. Through experiential learning opportunities, peer coaching, and expert instruction sessions, participants including in-service teachers, pre-service teachers, and ultimately their K-12 students, enhance their understanding of the processes and methods of science research. The initial engagement and exploration training has been provided to participants in the History of Winter (HOW) workshop since 2004. Supportive web-based multimedia resources utilized through modeling within the training program are available to participants online for continued later use within a classroom setting. The Thermochron Mission echoes the learning cycle embedded within the History of Winter Program. Emphasized are critical aspects of inquiry investigation including active and immersive experiences, opportunities for comparison and analysis of data, application of findings to new situations, and the communication of information in an appropriate forum. As a result, past HOW participants have utilized the Thermochron in settings as different as environmental studies through an outdoor education center and the study of acid mine drainage and its effect on local stream. In 2007, we collaborated with the FINNMARK 2007 and the GO NORTH expeditions, providing snow collection information and Thermochrons to gather a continual temperature record during these remote expeditions to the Arctic region. Both FINNMARK2007 and the POLAR Husky GoNorth 2007 dog sled expeditions took a complement of Thermochrons with multimedia instructions and the tools and protocols of the Global Snowflake Network (GSN), an International Polar Year project of the History of Winter Program, to measure temperature and the shape and characteristics of snow

    2014-01-01

    In the years surrounding World War II, solar house heating was seen by many American architects, journal editors, and policymakers as a necessary component of the expansion into suburbia. As the technological and financial aspects of home ownership came to take on broad social implications, design strategies of architectural modernism--including the expansive use of glass, the open plan and façade, and the flexible roof line--were seen as a means to construct suburbs that were responsive to anticipated concerns over materials allocations, over energy-resource scarcity, and over the economic challenges to postwar growth. As this article demonstrates, experiments in passive solar house design were a prominent means for envisioning the suburbs as an opportunity for new kinds of building and new ways of living. The article documents these developments and places them in the context of related efforts to think about the future.

    Chuang, Yi-Ting

    The advancement of mobile computing technology has provided diverse way for education. Combination of mobile devices and GIS tools has become a trend in many geospatial technology applications (i.e., Google Maps application on smartphones). This research aims to develop an iBook prototype (a GIS textbook) for GIS education on Apple iPads and to evaluate the effectiveness of adopting the GIS iBook in classes and fieldwork exercises. We conducted the evaluation tests in two GIS courses (GEOG104 and GEOG381) in Fall 2014 at San Diego State University. There are two main research questions in this study: (1) How to assess and evaluate the effectiveness of location-based learning exercises (from iBook) and fieldwork exercises for first-time GIS students? (2) What were major technical challenges and opportunities to utilize mobile device and mobile technology in GIS education? The procedures of developing and evaluating the prototype of the GIS iBook include creating two new chapters (chapter three: Wander the World through Remote Sensing Data and chapter four: Internet and Mobile GIS), interviewing five educators from high schools and community colleges, and improving the contents of the GIS iBook after the interview. There were 31 students who tested the GIS iBook and did a fieldwork exercise with iPads. The 31 students were required to finish five questionnaires after the exercise to express their user experiences and thoughts about the GIS iBook. Based on the result of questionnaires, most students preferred to take GIS classes with the free GIS iBook and thought fieldwork exercise can help their learning. The students also performed better in knowledge oriented survey after reading the GIS iBook. This research also adopts the SWOT analysis method to evaluate the prototype of the GIS iBook. The result of the SWOT analysis indicates that utilizing mobile device in GIS education does have a great potential value in enhancing student's understanding. The strengths of

    The relationship of the structural integrity of white matter tracts and cortical activity to motor functional outcomes in stroke patients is of particular interest in understanding mechanisms of brain structural and functional changes while recovering from stroke. This study aims to probe these underlying mechanisms using diffusion tensor imaging (DTI) and fMRI measures. We examined the structural integrity of the posterior limb of the internal capsule (PLIC) using DTI and corticomotor activity using motor-task fMRI in stroke patients who completed up to 15 sessions of rehabilitation therapy using Brain-Computer Interface (BCI) technology. We hypothesized that (1) the structural integrity of PLIC and corticomotor activity are affected by stroke; (2) changes in structural integrity and corticomotor activity following BCI intervention are related to motor recovery; (3) there is a potential relationship between structural integrity and corticomotor activity. We found that (1) the ipsilesional PLIC showed significantly decreased fractional anisotropy (FA) values when compared to the contralesional PLIC; (2) lower ipsilesional PLIC-FA values were significantly associated with worse motor outcomes (i.e., ipsilesional PLIC-FA and motor outcomes were positively correlated.); (3) lower ipsilesional PLIC-FA values were significantly associated with greater ipsilesional corticomotor activity during impaired-finger-tapping-task fMRI (i.e., ipsilesional PLIC-FA and ipsilesional corticomotor activity were negatively correlated), with an overall bilateral pattern of corticomotor activity observed; and (4) baseline FA values predicted motor recovery assessed after BCI intervention. These findings suggest that (1) greater vs. lesser microstructural integrity of the ipsilesional PLIC may contribute toward better vs. poor motor recovery respectively in the stroke-affected limb and demand lesser vs. greater cortical activity respectively from the ipsilesional motor cortex; and that (2

    Pre-clinical investigation of human CNS disorders relies heavily on mouse models. However these show low predictive validity for translational success to humans, partly due to the extensive use of rapid, high-throughput behavioral assays. Improved assays to monitor rodent behavior over longer time scales in a variety of contexts while still maintaining the efficiency of data collection associated with high-throughput assays are needed. We developed an apparatus that uses radio frequency identification device (RFID) technology to facilitate long-term automated monitoring of the behavior of mice in socially or structurally complex cage environments. Mice that were individually marked and implanted with transponders were placed in pairs in the apparatus, and their locations continuously tracked for 24 h. Video observation was used to validate the RFID readings. The apparatus and its associated software accurately tracked the locations of all mice, yielding information about each mouse's location over time, its diel activity patterns, and the amount of time it was in the same location as the other mouse in the pair. The information that can be efficiently collected in this apparatus has a variety of applications for pre-clinical research on human CNS disorders, for example major depressive disorder and autism spectrum disorder, in that it can be used to quantify validated endophenotypes or biomarkers of these disorders using rodent models. While the specific configuration of the apparatus described here was designed to answer particular experimental questions, it can be modified in various ways to accommodate different experimental designs.

With prefabrication technology, building construction could be done faster and cost lower price, along with a good craftsmanship quality. Until now, Indonesia is still facing settlements issues and one of them is housing backlog whose amount revolves around 13 Million units. Prefabricated houses potentially solve the settlement issue in Indonesia in a much faster way. Yet the development of prefabricated house has not been accepted well in the market yet, both by the producers and the consumers. This writing talks about the result of the research about the causes of the lack of development in Indonesia when it comes to prefabricated houses though the method of comparison; comparing prefabricated house with conventional house when it comes to its 1) productivity rate, 2) consumers preference and 3) infestation performance. The data is collected through survey methods, interview and questionnaires. The result shows that even though the productivity rate when it comes to quality and time is high, prefabricated house shows low productivity when it comes to cost because it requires greater cost than it is in conventional houses. Other than that, the lack of business development when it comes to prefabricated houses is caused by the low preference of consumers toward the product- because of its inflexibility and monotonous appearance. The infestation of prefabricated house development shows a low NPV and IRR. With a more proper infestation approach such as mass constructions with effective numbers, good flexibility, and various appearances, prefabricated house

    A nationwide investigation of radon levels in Syrian houses was carried out during the period 1991-1993. Passive radon diffusion dosemeters using polycarbonate detectors were distributed in houses all over Syria. Detectors were subjected to electrochemical etching to reveal latent tracks of alpha particles. The mean radon concentration in Syrian houses was found to be 45 Bq m -3 with some values several times higher. This investigation indicated that there were a few houses in Syria that require remedial action. Most houses that have high levels of radon were found in the southern area, especially in the Damascus governorate. The study also indicated that radon concentrations were higher in old houses built from mud with no tiling. (author)

  19. Department of Energy posture hearing. Hearing before the Committee on Science and Technology, US House of Representatives, Ninety-Ninth Congress, Second Session, February 19, 1986

    Energy Technology Data Exchange (ETDEWEB)

    1986-01-01

    Energy Secretary John S. Herrington was the principal witness at a hearing held to review the DOE budget request for fiscal year 1987, the first year to feel the effects of the Gramm-Rudman-Hollings legislation. The DOE requests a 20% increase in weapons research funding and a 60% decrease in conservation programs and a 50% cut in fusion research activity. Committee members challenged the assumption that energy problems are no longer pressing because of low oil prices, and suggested that the current lull presents an opportunity to prepare for the next crisis in energy supply and price. Herrington responded with an overview of the budget, which he described as lean and focused. Research funding emphasizes basic research and the need to overcome technological barriers, defederalization, and an open market approach.
