    Pregnancy rates after frozen embryo transfer (FET) have improved in recent years and are now approaching or even exceeding those obtained after fresh embryo transfer. This is partly due to improved laboratory techniques, but may also be caused by a more physiological hormonal and endometrial environment in FET cycles. Furthermore, the risk of ovarian hyperstimulation syndrome is practically eliminated in segmentation cycles followed by FET and the use of natural cycles in FETs may be beneficial for the postimplantational conditions of fetal development. However, a freeze-all strategy is not yet implemented as standard care due to limitations of large randomised trials showing a benefit of such a strategy. Thus, there is a need to test the concept against standard care in a randomised controlled design. This study aims to compare ongoing pregnancy and live birth rates between a freeze-all strategy with gonadotropin-releasing hormone (GnRH) agonist triggering versus human chorionic gonadotropin (hCG) trigger and fresh embryo transfer in a multicentre randomised controlled trial. Multicentre randomised, controlled, double-blinded trial of women undergoing assisted reproductive technology treatment including 424 normo-ovulatory women aged 18-39 years from Denmark and Sweden. Participants will be randomised (1:1) to either (1) GnRH agonist trigger and single vitrified-warmed blastocyst transfer in a subsequent hCG triggered natural menstrual cycle or (2) hCG trigger and single blastocyst transfer in the fresh (stimulated) cycle. The primary endpoint is to compare ongoing pregnancy rates per randomised patient in the two treatment groups after the first single blastocyst transfer. The study will be performed in accordance with the ethical principles in the Helsinki Declaration. The study is approved by the Scientific Ethical Committees in Denmark and Sweden. The results of the study will be publically disseminated. NCT02746562; Pre-results. © Article author(s) (or their

  5. A study on manufacturing and quality control technology of DUPIC fuel - The characteristics and the behavior of fission products in nuclear fuels including DUPIC

    Energy Technology Data Exchange (ETDEWEB)

    Park, Kwang Hun [Kyunghee University, Seoul (Korea, Republic of)

    1995-08-01

    The scope of this research can be divided into 2 parts; the problems related to f.p.`s up to the stage of producing DUPIC fuels and the effects of f.p.`s on the performance of nuclear fuels including DUPIC. The dose rate study of fresh and spent DUPIC fuels is done. Ba-137 m is major gamma-ray source in spent nuclear fuels after five year cooling time. Cs-137 makes a secular equilibrium with Ba-137 m, and elimination of Cs induces the disappearance of Ba-137 m, in an hour. Hence, care should be taken in collecting Cs during OREOX process. A defect model of irradiated nuclear fuels for the oxygen potential based on the defect structure of pure urania is devised. This model can give the oxygen pressure of ambient gas during the sintering of DUPIC fuels. The thermal conductivity decreases with the content of f.p.`s. The temperature distribution of DUPIC fuels is calculated from the thermal conductivity. The higher operating temperature of DUPIC fuels urges us to study the fuel performance difference. O/M shift due to steep temperature gradient is expected. However, the shift is negligible if the non-stoichiometry is small. 55 refs., 22 tabs., 52 figs. (author)

    The reasons for treating CBM water, end uses, reverse osmosis, pretreatment for reverse osmosis, and Newpark case studies are described. CBM water can be treated to make it suitable for injection, re-use, irrigation, or surface discharge. Usually the total dissolved solids (TDS) must be reduced by ion exchange or reverse osmosis with pretreatment. The concept of reverse osmosis and three types of applicable membrane processes are described: microfiltration and ultrafiltration, nanofiltration, and electrodialysis. The technologies used for pretreatment depend on the water quality and treatment goals, e.g. coagulation, flocculation and sand media filtration, softening, ion exchange, and nanofiltration. A Newpark case study is described for a water treatment plant at Boulder, Wyoming where evaporation was replaced by cavitation technology. The suitability of various treatment methods for Alberta CBM water is discussed. 21 figs., 1 tab.

  9. Expanding Health Technology Assessments to Include Effects on the Environment.

    2016-01-01

    There is growing awareness of the impact of human activity on the climate and the need to stem this impact. Public health care decision makers from Sweden and the United Kingdom have started examining environmental impacts when assessing new technologies. This article considers the case for incorporating environmental impacts into the health technology assessment (HTA) process and discusses the associated challenges. Two arguments favor incorporating environmental impacts into HTA: 1) environmental changes could directly affect people's health and 2) policy decision makers have broad mandates and objectives extending beyond health care. Two types of challenges hinder this process. First, the nascent evidence base is insufficient to support the accurate comparison of technologies' environmental impacts. Second, cost-utility analysis, which is favored by many HTA agencies, could capture some of the value of environmental impacts, especially those generating health impacts, but might not be suitable for addressing broader concerns. Both cost-benefit and multicriteria decision analyses are potential methods for evaluating health and environmental outcomes, but are less familiar to health care decision makers. Health care is an important and sizable sector of the economy that could warrant closer policy attention to its impact on the environment. Considerable work is needed to track decision makers' demands, augment the environmental evidence base, and develop robust methods for capturing and incorporating environmental data as part of HTA.

  11. High-efficiency photovoltaic technology including thermoelectric generation

    Science.gov (United States)

    Fisac, Miguel; Villasevil, Francesc X.; López, Antonio M.

    2014-04-01

    Nowadays, photovoltaic solar energy is a clean and reliable source for producing electric power. Most photovoltaic systems have been designed and built up for use in applications with low power requirements. The efficiency of solar cells is quite low, obtaining best results in monocrystalline silicon structures, with an efficiency of about 18%. When temperature rises, photovoltaic cell efficiency decreases, given that the short-circuit current is slightly increased, and the open-circuit voltage, fill factor and power output are reduced. To ensure that this does not affect performance, this paper describes how to interconnect photovoltaic and thermoelectric technology into a single structure. The temperature gradient in the solar panel is used to supply thermoelectric cells, which generate electricity, achieving a positive contribution to the total balance of the complete system.

    2008-01-01

    Project management is a critical skill for nurse informaticists who are in prominent roles developing and implementing clinical information systems. It should be included in the nursing informatics curriculum, as evidenced by its inclusion in informatics competencies and surveys of important skills for informaticists. The University of Pennsylvania School of Nursing includes project management in two of the four courses in the master's level informatics minor. Course content includes the phases of the project management process; the iterative unified process methodology; and related systems analysis and project management skills. During the introductory course, students learn about the project plan, requirements development, project feasibility, and executive summary documents. In the capstone course, students apply the system development life cycle and project management skills during precepted informatics projects. During this in situ experience, students learn, the preceptors benefit, and the institution better prepares its students for the real world.

    2014-03-01

    Fine-needle aspiration biopsy of the pancreas is indicated for sampling of solid and cystic masses. Preoperative cytologic diagnosis of pancreatic ductal adenocarcinoma and cystic lesions on cytology can be problematic, and ancillary studies may help confirm diagnosis. Ancillary studies in pancreatic cytology include special stains, immunohistochemistry, mutational analyses of specific genes, cyst fluid analysis of tumor markers and enzymes, and, in some instances, flow cytometry. Proteomics, microRNA sequencing, and whole-exome gene sequencing have been used to illustrate the progression of pancreatic neoplasms and identify key diagnostic markers. This article summarizes recent literature on ancillary studies in pancreatic fine-needle aspiration samples. Copyright © 2014 Elsevier Inc. All rights reserved.

    Kelley, J. H.

    1975-01-01

    The paper discusses the objectives of a hydrogen energy systems technology study directed toward determining future demand for hydrogen based on current trends and anticipated new uses and identifying the critical research and technology advancements required to meet this need with allowance for raw material limitations, economics, and environmental effects. Attention is focused on historic production and use of hydrogen, scenarios used as a basis for projections, projections of energy sources and uses, supply options, and technology requirements and needs. The study found more than a billion dollar annual usage of hydrogen, dominated by chemical-industry needs, supplied mostly from natural gas and petroleum feedstocks. Evaluation of the progress in developing nuclear fusion and solar energy sources relative to hydrogen production will be necessary to direct the pace and character of research and technology work in the advanced water-splitting areas.

    The advanced cogeneration technology economic optimization study (ACTEOS) was undertaken to extend the results of the cogeneration technology alternatives study (CTAS). Cost comparisons were made between designs involving advanced cogeneration technologies and designs involving either conventional cogeneration technologies or not involving cogeneration. For the specific equipment cost and fuel price assumptions made, it was found that: (1) coal based cogeneration systems offered appreciable cost savings over the no cogeneration case, while systems using coal derived liquids offered no costs savings; and (2) the advanced cogeneration systems provided somewhat larger cost savings than the conventional systems. Among the issues considered in the study included: (1) temporal variations in steam and electric demands; (2) requirements for reliability/standby capacity; (3) availability of discrete equipment sizes; (4) regional variations in fuel and electricity prices; (5) off design system performance; and (6) separate demand and energy charges for purchased electricity.

  17. Study on `Tannix` an absorbent for heavy metals including uranium

    Energy Technology Data Exchange (ETDEWEB)

    Nakamura, Yasuo [Mitsubishi Nuclear Fuel Co. Ltd., Tokyo (Japan)

    1997-09-01

    To treat radioactive wastes including uranium and transuranic elements such as plutonium, americium etc., development of an absorbent which can be used to absorb and isolate these elements without producing secondary wastes after treatment was attempted. And an absorbent has been successfully developed by polymerizing tannin, a natural product. It is known that tannin binds heavy metals including uranium resulting to produce their precipitates. There are some reports suggesting its absorption ability for uranium. However, tannin has not been used to isolate a heavy metal from a solution because it is soluble in water. Here, insolubilization of tannin was attempted and a manufacturing method for a gelatinized insoluble tannin named as ``Tannix`` was established. Wattle tannin extracted from Mimosa pudica produced in Africa was dissolved in an alkaline solution and gelatinized by heating after the addition of formalin. Thus obtained insoluble tannin was used after crushing and sieving. This product, ``Tannix`` was able to absorb more than 99% of uranium in the waste. And the absorbed Tannin could be degraded by incineration even at a low temperature, leaving only uranium, but not producing any secondary product. (M.N.)

  19. Studies of technology in prehistoric archaeology

    Directory of Open Access Journals (Sweden)

    Vitezović Selena

    2011-01-01

    Full Text Available Technology studies have always been the most important focus of archaeology, as a science which analyzes human past through the study of material culture. To say that something is technological in archaeology, means to put the concept of technology in the centre of theoretical studies, and to study not only the form of the object, but also the entire sequence of technological factors, from raw material choice, mode of use, up to the reasons for abandonment. The concept of technology in anthropology and archaeology is based on the original meaning of the word τεχνη in ancient Greek, meaning the skill, i. e., to study how something is being done. Such a concept of technology as a skill or mode of doing something was for the first time outlined by the French anthropologist Marcel Mauss, whose starting point was that every technological statement was at the same time social or cultural statement and that technological choices have social foundations. Pierre Lemonnier further developed the anthropology of technology, focusing on the question of technological choices, as well as numerous other anthropologists. In archaeology, the most important contribution to the study of technology was the work of André Leroi-Gourhan, who created the concept of chaîne opératoire, as an analytical tool for studying the mode of creating, using and discarding an artefact, starting with raw material acquisition, mode of manufacture, final form, use (including caching, breaking and repairing up to the final discarding. It is not only about reconstructing the algorithmic sequence of operations in creating one object, but it is a complex analysis of operational chain within one society which includes the analysis of technological choices. The analyses of technologies today include a variety of different approaches, most of them with emphasis on the cultural and social aspects of technology. The analysis of bone industry in the Early and Middle Neolithic in central

Some students can take this situation in their stride, and some fall to pieces, getting lost amid the maze of books and tangling themselves into mental knots. When we first embark on a course of study, we are often thrown in at the deep end and left to sink or swim. Studying is a skill, not something we are born with a natural aptitude for.

    1994-01-01

    The original FTS concept for Space Station Freedom (SSF) was to provide telerobotic assistance to enhance crew activity and safety and to reduce crew EVA (Extra Vehicular Activity) activity. The first flight of the FTS manipulator systems would demonstrate several candidate tasks and would verify manipulator performance parameters. These first flight tasks included unlocking a SSF Truss Joint, mating/demating a fluid coupling, contact following of a contour board, demonstrating peg-in-hole assembly, and grasping and moving a mass. Future tasks foreseen for the FTS system included ORU (Orbit Replaceable Unit) change-out, Hubble Space Telescope Servicing, Gamma Ray Observatory refueling, and several in-situ SSF servicing and maintenance tasks. Operation of the FTS was planned to evolve from teleoperation to fully autonomous execution of many tasks. This wide range of mission tasks combined with the desire to evolve toward fully autonomy forced several requirements which may seen extremely demanding to the telerobotics community. The FTS requirements appear to have been created to accommodate the open-ended evolution plan such that operational evolution would not be impeded by function limitations. A recommendation arising from the FTS program to remedy the possible impacts from such ambitious requirements is to analyze candidate robotic tasks. Based on these task analyses, operational impacts against development impacts were weighed prior to requirements definition. Many of the FTS requirements discussed in the following sections greatly influenced the development cost and schedule of the FTS manipulator. The FTS manipulator has been assembled at Martin Marietta and is currently in testing. Successful component tests indicate a manipulator which achieves unprecedented performance specifications.

  6. Carbon Dioxide Reduction Technology Trade Study

    For long-term human missions, a closed-loop atmosphere revitalization system (ARS) is essential to minimize consumables. A carbon dioxide (CO2) reduction technology is used to reclaim oxygen (O2) from metabolic CO2 and is vital to reduce the delivery mass of metabolic O2. A key step in closing the loop for ARS will include a proper CO2 reduction subsystem that is reliable and with low equivalent system mass (ESM). Sabatier and Bosch CO2 reduction are two traditional CO2 reduction subsystems (CRS). Although a Sabatier CRS has been delivered to International Space Station (ISS) and is an important step toward closing the ISS ARS loop, it recovers only 50% of the available O2 in CO2. A Bosch CRS is able to reclaim all O2 in CO2. However, due to continuous carbon deposition on the catalyst surface, the penalties of replacing spent catalysts and reactors and crew time in a Bosch CRS are significant. Recently, technologies have been developed for recovering hydrogen (H2) from Sabatier-product methane (CH4). These include methane pyrolysis using a microwave plasma, catalytic thermal pyrolysis of CH4 and thermal pyrolysis of CH4. Further, development in Sabatier reactor designs based on microchannel and microlith technology could open up opportunities in reducing system mass and enhancing system control. Improvements in Bosch CRS conversion have also been reported. In addition, co-electrolysis of steam and CO2 is a new technology that integrates oxygen generation and CO2 reduction functions in a single system. A co-electrolysis unit followed by either a Sabatier or a carbon formation reactor based on Bosch chemistry could improve the overall competitiveness of an integrated O2 generation and CO2 reduction subsystem. This study evaluates all these CO2 reduction technologies, conducts water mass balances for required external supply of water for 1-, 5- and 10-yr missions, evaluates mass, volume, power, cooling and resupply requirements of various technologies.

    To evaluate (1) how often observational studies are included in comparative effectiveness reviews (CERs); (2) the rationale for including observational studies; (3) how data from observational studies are appraised, analyzed, and graded; and (4) the impact of observational studies on strength of evidence (SOE) and conclusions. Descriptive study of 23 CERs published through the Effective Health Care Program of the U.S. Agency for Healthcare Research and Quality. Authors searched for observational studies in 20 CERs, of which 18 included a median of 11 (interquartile range, 2-31) studies. Sixteen CERs incorporated the observational studies in their SOE assessments. Seventy-eight comparisons from 12 CERs included evidence from both trials and observational studies; observational studies had an impact on SOE and conclusions for 19 (24%) comparisons. There was diversity across the CERs regarding decisions to include observational studies; study designs considered; and approaches used to appraise, synthesize, and grade SOE. Reporting and methods guidance are needed to ensure clarity and consistency in how observational studies are incorporated in CERs. It was not always clear that observational studies added value in light of the additional resources needed to search for, select, appraise, and analyze such studies. Copyright © 2014 Elsevier Inc.

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

    2013-12-01

    Genomics and proteomics have emerged as key technologies in biomedical research, resulting in a surge of interest in training by investigators keen to incorporate these technologies into their research. At least two types of training can be envisioned in order to produce meaningful results, quality publications and successful grant applications: (1) immediate short-term training workshops and (2) long-term graduate education or visiting scientist programs. We aimed to fill the former need by providing a comprehensive hands-on training course in genomics, proteomics and informatics in a coherent, experimentally-based framework. This was accomplished through a National Heart, Lung, and Blood Institute (NHLBI)-sponsored 10-day Genomics and Proteomics Hands-on Workshop held at National Jewish Health (NJH) and the University of Colorado School of Medicine (UCD). The course content included comprehensive lectures and laboratories in mass spectrometry and genomics technologies, extensive hands-on experience with instrumentation and software, video demonstrations, optional workshops, online sessions, invited keynote speakers, and local and national guest faculty. Here we describe the detailed curriculum and present the results of short- and long-term evaluations from course attendees. Our educational program consistently received positive reviews from participants and had a substantial impact on grant writing and review, manuscript submissions and publications.

  11. What is technology? A study of fifth and eighth grade student ideas about the Nature of Technology

    Science.gov (United States)

    Digironimo, Nicole

    Most, if not all, standards for science and technology education and curriculum indicate that knowledge of the Nature of Technology is an educational goal, yet the literature lacks an established definition for the Nature of Technology. Additionally, the research on student ideas about the Nature of Technology is insufficient. After reviewing the literature on science and technology education, the philosophy of technology, and the history of technology, this study presents an internally consistent definition for the Nature of Technology. This definition illustrates how the Nature of Technology includes five dimensions: Technology as Artifacts; Technology as a Creation Process; Technology as a Human Practice; The History of Technology; and The Current Role of Technology. Using an interview protocol developed for this study, a small group of 5th and 8th grade students were interviewed to ascertain their ideas about the Nature of Technology. The results indicate that there are a variety of ideas present in the thinking of young people. All of the participants expressed one of two ideas about technological artifacts: technological artifacts are electronic or technological artifacts are invented. All of the participants identified particular skills needed to invent technological artifacts; some of the participants included mobility and concluded that disabled people cannot be inventors. Despite their experiences with technological artifacts (including educational technology tools), a few of the participants were uncertain whether they would identify themselves as technological. More than half of the participants did not believe older artifacts can still be considered technology. Most of the participants were apprehensive about our technological future; the main issue expressed by the participants was the environment. Other than environmental concerns, most of the participants were unable to identify global issues regarding technological use and development. Overall

    2016-12-01

    This work will present the technological processes necessary to experimentally obtain plasmonic metasurfaces for developing flat optical components or diffractive optical elements (DOE) which have reflexion functionalities. This class of metasurfaces offers the possibility to manipulate the beam shape using an array of metallic nanoscale elements patterned on a substrate. The main feature of these structures is that one can manipulate the phase behavior by modifying some of the geometrical parameters of the nano-antennas in order to achieve the required phase shift values for the desired applications. The first important step in experimentally obtaining a plasmonic metasurface structures is the electron beam lithography (EBL) followed by the lift-off method. Due to the small sizes of the gold nano-antennas and tight periodicity of the array a number of impediments can emerge in experimentally obtaining such geometries which can be overcome by the parameter optimization of the employed technologies.

    Full text: Two research initiatives by Pandion Systems, funded by the US Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE), are addressing the enormous challenges of conducting offshore wind-wildlife risk/impact studies by providing new wildlife sensing technologies that surmount some of the limitations of previous techniques. Both initiatives rest on the shoulders of pioneering European studies and experience. One entails the development of a remote-operating acoustic/thermographic detector. This device, designed with input from the Danish National Environmental Research Institute (NERI) and Cornell Laboratory of Ornithology (CLO), will provide species-specific occurrence data, as well as flight altitude estimation, for vocalizing flying wildlife that flies within a detection beam that corresponds roughly to the rotor swept zone of a single, commercial marine wind turbine. While the detection beam is small and limitations exist for silently flying animals, this device will be capable of providing information on bats and on federally-listed bird species that has been difficult or impossible to achieve with other methods. A preliminary version of this device was developed in 2009-2010 in a BOEMRE-funded pilot study, and a sea-worthy device is currently being developed, scheduled for initial deployment on the US Atlantic Outer Continental Shelf (AOCS) in summer, 2011. A second initiative is targeted at developing a high-definition aerial survey protocol capable of providing a safe, cost-effective, reproducible snapshot of bird, marine mammal, and sea turtle distribution on the entire AOCS. This research, being conducted with a team of technologists and biologists including scientists from the British Trust for Ornithology (BTO), entails conducting a series of pilot experiments in spring, 2011 with a variety of different aircraft, cameras, flight altitudes, and image resolutions, to determine optimum protocols for the large-scale surveys.

    Bacteria have traditionally been studied as single-cell organisms. In laboratory settings, aerobic bacteria are usually cultured in aerated flasks, where the cells are considered essentially homogenous. However, in many natural environments, bacteria and other microorganisms grow in mixed communities, often associated with surfaces. Biofilms are comprised of surface-associated microorganisms, their extracellular matrix material, and environmental chemicals that have adsorbed to the bacteria or their matrix material. While this definition of a biofilm is fairly simple, biofilms are complex and dynamic. Our understanding of the activities of individual biofilm cells and whole biofilm systems has developed rapidly, due in part to advances in molecular, analytical, and imaging tools and the miniaturization of tools designed to characterize biofilms at the enzyme level, cellular level, and systems level.

    For environmental and health effects due to increasing levels of pollution in the atmosphere, it is necessary to develop environmentally sound technologies for the treatment of greenhouse gases (CO{sub 2}, CH{sub 4}, CFC, etc.) and acid gases (SOx, NOx, etc.). Specifically, advanced technology for CO{sub 2} capturing is currently one of the most important environmental issues in worldwide. {sup 14}CO{sub 2}, specially which has been gradually emerging issue in the nuclear facilities, is generated about 330 ppm from the CANDU (Canadian Deuterium Uranium Reactor) nuclear power plant and the DUPIC (Direct Use of spent PWR fuel in CANDU reactors) process which is the process of spent fuel treatment. For this purpose, it is necessary to develop the most efficient treatment technology of CO{sub 2} capture by various lime materials in semi- or dry process, it should be also considering a removal performance, waste recycling and safety of disposal. In order to develop a highly active slaked lime as a sorbent for CO{sub 2} and high temperature desulfurization, macroporous slaked lime is necessarily prepared by modified swelling process and equipment, which was developed under carrying out this project. And also for the optimal removal process of off-gases the removal performance tests of various sorbents and the effects of relative humidity and bed depth on the removal capacity must be considered.

    The Planetary Science Division (PSD) within the National Aeronautics and Space Administrations (NASA) Science Mission Directorate (SMD) at NASA Headquarters sought to understand how to better realize a scientific return on spacecraft system technology investments currently being funded. In order to achieve this objective, a team at NASA Glenn Research Center was tasked with surveying the science and mission communities to collect their insight on technology infusion and additionally sought inputs from industry, universities, and other organizations involved with proposing for future PSD missions. This survey was undertaken by issuing a Request for Information (RFI) activity that requested input from the proposing community on present technology infusion efforts. The Technology Infusion Study was initiated in March 2013 with the release of the RFI request. The evaluation team compiled and assessed this input in order to provide PSD with recommendations on how to effectively infuse new spacecraft systems technologies that it develops into future competed missions enabling increased scientific discoveries, lower mission cost, or both. This team is comprised of personnel from the Radioisotope Power Systems (RPS) Program and the In-Space Propulsion Technology (ISPT) Program staff.The RFI survey covered two aspects of technology infusion: 1) General Insight, including: their assessment of barriers to technology infusion as related to infusion approach; technology readiness; information and documentation products; communication; integration considerations; interaction with technology development areas; cost-capped mission areas; risk considerations; system level impacts and implementation; and mission pull. 2) Specific technologies from the most recent PSD Announcements of Opportunities (AOs): The Advanced Stirling Radioisotope Generator (ASRG), aerocapture and aeroshell hardware technologies, the NASA Evolutionary Xenon Thruster (NEXT) ion propulsion system, and the

    In recent years, Russia adopted a policy towards increasing of the share of renewable energy in total amount of used energy, albeit with some delay comparing to the EU countries and the USA. It was expected that the use of biofuels over time will reduce significantly the dependency of Russian economy on fossil fuels, increase its competitiveness, and increase Russian contribution to the prevention of global climate changes. Russia has significant bio-energy potential and resources which are characterized by great diversity due to the large extent of the territory, which require systematic studies and environmental assessment of used bio-energy technologies. Results of research carried at the Laboratory of agroecological monitoring, modeling and prediction of ecosystems RSAU-MTAA demonstrated significant differences in the assessment of the environmental, economic and social effects of biofuel production and use, depending on the species of bio-energy crops, regional soil-ecological and agro-climatic characteristics, applied farming systems and production processes. The total area of temporarily unused and fallow land, which could be allocated to the active agricultural use in Russia, according to various estimates, ranges from 20 to 33 million hectares, which removes the problem, typical of most European countries, of adverse agro-ecological changes in land use connected with the expansion of bio-energy crops cultivation. However, the expansion of biofuel production through the use of fallow land and conversion of natural lands has as a consequence the problem of greenhouse gas emissions due to land use changes, which, according to FAO, could be even higher than CO2 emission from fossil fuels for some of bio-energy raw materials and production systems. Assessment of the total impacts of biofuels on greenhouse gas emissions in the Russian conditions should be based on regionally adapted calculations of flows throughout the entire life cycle of production, taking

    The aim of this study was to assess cardiovascular risk (CVR) by investigating the prevalence of CVR factors (CVRF), target organ damage (TOD), and cardiovascular disease (CVD) in general population of the health area of Toledo, Spain. Epidemiological and observational study that analysed a sample from the general population aged 18years or older, randomly selected from a database of health cards stratified by age and gender. Clinical history, physical examination, and complementary tests were performed. Total blood and serum samples were frozen at -85°C to evaluate genetic studies in the future. Standard statistical analysis was performed. CVR was assessed by the SCORE scale calibrated for the Spanish population, and the Framingham Heart Study scale. A total of 1,500 individuals (mean age 49.1±15.8years, 55.6% women) were included.

    The Advanced Fuel Cycle Initiative (AFCI) Safeguards Campaign aims to develop safeguards technologies and processes that will significantly reduce the risk of proliferation in the U.S. nuclear fuel cycle of tomorrow. The Safeguards Enhancement Study was chartered with identifying promising research and development (R&D) directions over timescales both near-term and long-term, and under safeguards oversight both domestic and international. This technology development roadmap documents recognized gaps and needs in the safeguarding of nuclear fuel cycles, and outlines corresponding performance targets for each of those needs. Drawing on the collective expertise of technologists and user-representatives, a list of over 30 technologies that have the potential to meet those needs was developed, along with brief summaries of each candidate technology. Each summary describes the potential impact of that technology, key research questions to be addressed, and prospective development milestones that could lead to a definitive viability or performance assessment. Important programmatic linkages between U.S. agencies and offices are also described, reflecting the emergence of several safeguards R&D programs in the U.S. and the reinvigoration of nuclear fuel cycles across the globe.

    During the first two weeks of September 2005, the National Aeronautics and Space Administration (NASA) Johnson Space Center (JSC) Advanced Extravehicular Activity (AEVA) team led the field test portion of the 2005 Research and Technology Studies (RATS). The Desert RATS field test activity is the culmination of the various individual science and advanced engineering discipline areas year-long technology and operations development efforts into a coordinated field test demonstration under representative (analog) planetary surface terrain conditions. The purpose of the RATS is to drive out preliminary exploration concept of operations EVA system requirements by providing hands-on experience with simulated planetary surface exploration extravehicular activity (EVA) hardware and procedures. The RATS activities also are of significant importance in helping to develop the necessary levels of technical skills and experience for the next generation of engineers, scientists, technicians, and astronauts who will be responsible for realizing the goals of the Constellation Program. The 2005 Desert RATS was the eighth RATS field test and was the most systems-oriented, integrated field test to date with participants from NASA field centers, the United States Geologic Survey (USGS), industry partners, and research institutes. Each week of the test, the 2005 RATS addressed specific sets of objectives. The first week focused on the performance of surface science astro-biological sampling operations, including planetary protection considerations and procedures. The second week supported evaluation of the Science, Crew, Operations, and Utility Testbed (SCOUT) proto-type rover and its sub-systems. Throughout the duration of the field test, the Communications, Avionics, and Infomatics pack (CAI-pack) was tested. This year the CAI-pack served to provide information on surface navigation, science sample collection procedures, and EVA timeline awareness. Additionally, 2005 was the first

    To promote the succession of history of and the creative use of industrial science technologies, the paper made lists and databases of the articles of industrial technology museums and material halls in Japan. Record/preservation and collection/systematization of history of the industrial technology is useful for forming bases necessary for promotion of future research/development and international contribution. Museums and material halls are the fields for making comprehensive and practical activities. The data were made as one of the basic databases as the first step for promoting activities for examining the technical succession situation in a long term range continuously and systematically. In the classification of the data, the energy relation was divided into electric power, nuclear power, oil, coal, gas and energy in general. Others were classified into metal/mine, electricity/electronics/communication, chemistry/food, ship building/heavy machinery, printing/precision instrument, and textile/spinning. Moreover, the traffic relation was classified into railroad, automobiles/two-wheeled vehicles, airline/space, and ships. Items were also set of life relation, civil engineering/architecture, and general. The total number of the museums for the survey reached 208.

    2002-01-01

    We have established the first Java 3D-enabled CAVE (CAVE automated virtual environment). The Java application programming interface allows the complete separation of the program development from the program execution, opening new application domains for the CAVE technology. Programs can be developed on any Java-enabled computer platform, including Windows, Macintosh, and Linux workstations, and executed in the CAVE without modification. The introduction of Java, one of the major programming environments for bioinformatics, into the CAVE environment allows the rapid development applications for genome research, especially for the analysis of the spatial and temporal data that are being produced by functional genomics experiments. The CAVE technology will play a major role in the modeling of biological systems that is necessary to understand how these systems are organized and how they function.

  1. Canadian entrepreneur looks to Utah oil sands : possible hurdles include gaining acceptance for a new technology, funding and regulatory approval

    Diekmeyer, P.

    2010-09-15

    Alberta-based Earth Energy Resources has chosen Utah for its first major oilsand development project. Utah has excellent oil sands resources, but most cannot be economically extracted using conventional methods. The president of Earth Energy Resources has proposed to use new technologies, processes and workflow methods to make resource extraction economically viable. The company currently holds a 100 percent interest in 3,170 hectares under lease from the State of Utah School and Institutional Trust Lands Administration (SITLA) in the PR Spring deposit. The recoverable high-quality bitumen is estimated at 250 million barrels. The oil sands in Utah are disaggregated and spread out over a relatively wide area. The bitumen quality is very similar to that found in the Athabasca deposit, but it has a much lower sulphur content. Earth Energy Resources plans on using the Ophus Process which involves a series of small 2,000 barrel per day production facilities that can be easily set up, and moved as the resources in one particular area are recovered. Production could be expanded as needed by the addition of more facilities. An environmentally sound citrus-based extraction chemical will replace much of the mechanical energy and caustic soda mixture used in the Clark Process. The new energy and water efficient process will significantly reduce the quantity of middlings produced in the process, thereby eliminating the need for tailings ponds and reducing environmental impacts. 1 fig.

    2017-02-01

    Systematic reviews and maps should be based on the best available evidence, and reviewers should make all reasonable efforts to source and include potentially relevant studies. However, reviewers may not be able to consider all existing evidence, since some data and studies may not be publicly available. Including non-public studies in reviews provides a valuable opportunity to increase systematic review/map comprehensiveness, potentially mitigating negative impacts of publication bias. Studies may be non-public for many reasons: some may still be in the process of being published (publication can take a long time); some may not be published due to author/publisher restrictions; publication bias may make it difficult to publish non-significant or negative results. Here, we consider what forms these non-public studies may take and the implications of including them in systematic reviews and maps. Reviewers should carefully consider the advantages and disadvantages of including non-public studies, weighing risks of bias against benefits of increased comprehensiveness. As with all systematic reviews and maps, reviewers must be transparent about methods used to obtain data and avoid risks of bias in their synthesis. We make tentative suggestions for reviewers in situations where non-public data may be present in an evidence base.

    Full Text Available Abstract Background There is an increasing number of meta-analyses including data from non-randomized studies for therapeutic evaluation. We aimed to systematically assess the methods used in meta-analyses including non-randomized studies evaluating therapeutic interventions. Methods For this methodological review, we searched MEDLINE via PubMed, from January 1, 2013 to December 31, 2013 for meta-analyses including at least one non-randomized study evaluating therapeutic interventions. Etiological assessments and meta-analyses with no comparison group were excluded. Two reviewers independently assessed the general characteristics and key methodological components of the systematic review process and meta-analysis methods. Results One hundred eighty eight meta-analyses were selected: 119 included both randomized controlled trials (RCTs and non-randomized studies of interventions (NRSI and 69 only NRSI. Half of the meta-analyses (n = 92, 49 % evaluated non-pharmacological interventions. “Grey literature” was searched for 72 meta-analyses (38 %. An assessment of methodological quality or risk of bias was reported in 135 meta-analyses (72 % but this assessment considered the risk of confounding bias in only 33 meta-analyses (18 %. In 130 meta-analyses (69 %, the design of each NRSI was not clearly specified. In 131 (70 %, whether crude or adjusted estimates of treatment effect for NRSI were combined was unclear or not reported. Heterogeneity across studies was assessed in 182 meta-analyses (97 % and further explored in 157 (84 %. Reporting bias was assessed in 127 (68 %. Conclusions Some key methodological components of the systematic review process—search for grey literature, description of the type of NRSI included, assessment of risk of confounding bias and reporting of whether crude or adjusted estimates were combined—are not adequately carried out or reported in meta-analyses including NRSI.

  5. Proteomic Technologies for the Study of Osteosarcoma

    2012-01-01

    Full Text Available Osteosarcoma is the most common primary bone cancer of children and is established during stages of rapid bone growth. The disease is a consequence of immature osteoblast differentiation, which gives way to a rapidly synthesized incompletely mineralized and disorganized bone matrix. The mechanism of osteosarcoma tumorogenesis is poorly understood, and few proteomic studies have been used to interrogate the disease thus far. Accordingly, these studies have identified proteins that have been known to be associated with other malignancies, rather than being osteosarcoma specific. In this paper, we focus on the growing list of available state-of-the-art proteomic technologies and their specific application to the discovery of novel osteosarcoma diagnostic and therapeutic targets. The current signaling markers/pathways associated with primary and metastatic osteosarcoma that have been identified by early-stage proteomic technologies thus far are also described.

    This paper introduces the characteristics of Computed Tomography (CT) technology and reviews its history, current situation, representative achievements, and use of using CT technology on frozen soil study, including auxiliary equipment specially de-signed for frozen soil studies. CT numbers are used to analyze frozen soil internal structure change, defining and exploring dam-age evolution, and use of CT images on observing soil mesostructure. Finally, this paper presents existing problems confronted by using CT in frozen soil studies, possible solutions and challenges, among which, we introduce high quality CT image processing for frozen soils, and relations between CT number change and each component change on frozen soil samples within the region of interest. It is shown that present CT technology is one of the most ideal and effective technology to study frozen soil mesostructure using non-destructive testing. CT technology will play a key role in the study and development in the field of frozen soil by means of auxiliary equipment and the digital imaging processing.

  7. THE EVALUATION OF FOLK CULTURE ELEMENTS INCLUDING IN PRIMARY SCHOOL SOCIAL STUDIES TEXTBOOKS

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Folk culture is a total of common values, behaviors and ways of living patterns produced, kept alive, transferred to the next generations orally or written, informal education and concentrating on traditional areas. There is no doubt that transferring folk culture to the next generations will contribute to the protection of national identities against globalization, an inevitable process. The way of its realization is based on education. One of the most important lessons in which folk culture can be transferred to the young generations in primary education is social studies. The aim of this research is to reveal to what extend folk culture elements were included in 4th,5th, 6th, 7th grade social studies textbooks and workbooks. At the end of the research, which was carried out with scanning model and content analysis, it was found that seasonal festivals, children's games, marriage, processing, women's clothing and dress-ornament, dining-food-beverage, Karagoz, proverbs, folk music/instrument, Turkish folk dances, wrestling, and javelin folk culture elements were mostly included in the textbooks. Since social studies is an interdisciplinary field, it was presented with samples that all the elements of folk culture can be included in social studies textbooks.

    Barnatskiĭ, V V; Grigor'eva, V D; Pershin, S B; Derevnina, N A; Gontar', E B

    2005-01-01

    The immune system was studied in 90 patients with seronegative spondylarthritis (SNSA). Of them, 60 patients had ankylosing spondylarthritis (30 patients with central and 30 patients with peripheral forms) and 30 patients with reactive arthritis. SNSA patients were found to have secondary immunodeficiency. Cellular immunity was characterized by a decreased count of T mu (helper cells), an increased count of T gamma (cytotoxic/suppressors) and suppressed functional activity of lymphocytes, humoral immunity--by a high concentration of circulating immune complexes in an increased concentration of serum immunoglobulins. Integral assessment of the changes in the immune system and clinical data in SNSA patients leads to the conclusion that water radon baths and decimetric wave therapy reach the highest efficacy in ankylosing spondylarthritis while water radon baths and low frequency ultrasound--in reactive arthritis, a complex of water radon baths and ultraphonophoresis of hydrocortisone--in ankylosing spondylarthritis and reactive arthritis.

  9. How should clinical data be included in experimental studies of cancer immunology?

    Science.gov (United States)

    Gjertsen, Bjørn Tore; Bruserud, Øystein

    2004-08-01

    Patients diagnosed with the same malignant disease are often heterogeneous with regard to age, complications, malignant cell morphology and tumor histology, disease stage, prognostic parameters, and previous therapy. Many of these factors can affect immunocompetent cells or influence the malignant cell susceptibility to immunotherapy. Summaries of relevant clinical information should therefore be included in cancer immunology studies to increase the present as well as the future scientific impact. Guidelines for selection of relevant information are suggested in the article.

    2011-01-01

    OBJECTIVE: To summarize Cochrane reviews of acupuncture for neurological disorders, and characteristics of included reviews and studies.DATA SOURCES: A computer-based online search of the Cochrane Library (Issue 7 of 12, July 2010) was performed with the key word "acupuncture" and systematic evaluations for acupuncture for neurological disorders were screened.STUDY SELECTION: Systematic reviews on acupuncture in the treatment of neurological disorders were included, and the characteristics of these reviews were analyzed based on methods recommended by the Cochrane collaboration.MAIN OUTCOME MEASURES: Basic characteristics, methodological quality, main reasons for excluding trials, results and conclusions of Cochrane reviews were assessed.RESULTS: A total of 18 Cochrane systematic reviews were included, including 13 completed reviews and five research protocols. The 13 completed reviews involved 111 randomized controlled trials, including 43 trials (38.7%) conducted in China, 47 trials (42.3%) using sham-acupuncture or placebo as control, 15 trials (13.5%) with relatively high quality, 91 trials (81.9%) reporting data on follow-up. Primary outcomes used in the Cochrane reviews were reported by 65 trials (58.6%), and adverse events were reported in 11 trials (9.9%). Two hundred and eighty three trials were excluded. Two reviews on headache suggested that acupuncture is a valuable non-drug treatment for patients with chronic or recurrent headache, and has better curative effects on migraine compared with preventative drug treatment. CONCLUSION: Of the Cochrane reviews on acupuncture in the treatment of neurological disorders, two reviews evaluating the efficacy of acupuncture in treating headaches drew positive conculsions, while other reviews did not obtain positive conclusions due to a small sample size or low methodological quality. The methodological quality of acupuncture trials needs further improvement.

    Cantwell Wilson, Brenda

    2002-03-01

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

    Workplace aggression remains an important source of distress among nurses and midwives and has negative effects on staff health, patient care and organisations' reputation and fiscal health. To report on the nature and extent of workplace aggression, including bullying experienced by nurses and midwives in Victoria, Australia. A descriptive study design was chosen. The Nurses Board of Victoria posted 5000 surveys to the randomly selected registered nurses and midwives in Victoria, Australia, in 2010. The participants were asked about their experiences of violence (from clients) and bullying (from colleagues) within their most recent four working weeks. In addition, the study investigated staff actions following incidents, staff training and safety at work, and what staff believe contribute to incidents. Data analysis involved descriptive statistics, including frequencies and percentages. Chi square tests and P value were used to assess differences in categorical data. 1495 returned questionnaires were included in the study (30% response rate). Over half of the participants (52%) experienced some form of workplace aggression. Thirty-six percent experienced violence mostly from patients or their visitors/relatives and 32% experienced bullying mostly from colleagues or from their managers/supervisors. Significant differences were found between those who experienced aggression from patients and those who were bullied in respect to handling of incidents; factors thought to contribute to incidents; and organisations' handling of incidents. The study suggests that staff are less worried by patient initiated aggression compared to bullying from colleagues. For all types of aggression, respondents clearly wanted better/more realistic training, as well as enforcement of policies and support when incidents arise. Copyright © 2012 Elsevier Ltd.

  16. Consumption of peptide-included and free tryptophan induced by peroxyl radicals: A kinetic study.

    Science.gov (United States)

    Fuentes, E; López-Alarcón, C

    2014-10-01

    It is well-known that tryptophan residues are efficiently oxidized by peroxyl radicals, generating kynurenine, and N-formyl kynurenine as well as hydroperoxide derivatives as products. In the present work we studied the kinetic of such reaction employing free and peptide-included tryptophan. Two azocompounds were used to produce peroxyl radicals: AAPH (2,2'-Azobis(2-methylpropionamidine) dihydrochloride) and ABCVA (4,4'-Azobis(4-cyanovaleric acid)), which generate cationic and anionic peroxyl radicals, respectively. Tryptophan consumption was assessed by fluorescence spectroscopy and the reactions were carried out in phosphate buffer (75mM, pH 7.4) at 45°C. Only a slight effect of the peroxyl radical charge was evidenced on the consumption of free tryptophan and the dipeptide Gly-Trp. Employing AAPH as peroxyl radical source, at low free tryptophan concentrations (1-10µM) near 0.3 mol of tryptophan were consumed per each mol of peroxyl radicals introduced into the system. However, at high free tryptophan concentrations (100µM-1mM) such stoichiometry increased in a tryptophan concentration-way. At 1mM three moles of tryptophan were consumed per mol of AAPH-derived peroxyl radicals, evidencing the presence of chain reactions. A similar behavior was observed when di and tri-peptides (Gly-Trp, Trp-Gly, Gly-Trp-Gly, Trp-Ala, Ala-Trp-Ala) were studied. Nonetheless, at low initial concentration (5µM), the initial consumption rate of tryptophan included in the peptides was two times higher than free tryptophan. In contrast, at high concentration (1mM) free and peptide-included tryptophan showed similar initial consumption rates. These results could be explained considering a disproportionation process of tryptophanyl radicals at low free tryptophan concentrations, a process that would be inhibited when tryptophan is included in peptides.

    Within the last few years, new technology has come to play an important part in our professional and private daily environment. Healthcare has not escaped this progressive mutation with computers reaching the bedside. Clinical research has also shown growing interest in these new tools available to the clinical investigator, the patient, as well as to specialist departments for diagnosis and follow-up of patients, and to the different professions in clinical research. If the use of new technology seems to make life easier, by centralizing data or by simplifying data-sharing between different teams, it is still a matter of private data which must remain reliable, confidential and secure, whether it is being used in ordinary healthcare or in academic or industrial research. The aim of the round table was to estimate the impact of new information technology applied to clinical trials (including source data-medical records) and to human and drug research. First, an inventory was made of the development of these new technologies in the healthcare system. The second point developed was identification of expected benefits in order to issue guidelines for their good use and hazard warnings in clinical trials. Finally, the impact of these new technologies on the investigator as well as the project manager was analysed.

  18. Measuring Outcomes in Adult Weight Loss Studies That Include Diet and Physical Activity: A Systematic Review

    Rachel A. Millstein

    2014-01-01

    Full Text Available Background. Measuring success of obesity interventions is critical. Several methods measure weight loss outcomes but there is no consensus on best practices. This systematic review evaluates relevant outcomes (weight loss, BMI, % body fat, and fat mass to determine which might be the best indicator(s of success. Methods. Eligible articles described adult weight loss interventions that included diet and physical activity and a measure of weight or BMI change and body composition change. Results. 28 full-text articles met inclusion criteria. Subjects, settings, intervention lengths, and intensities varied. All studies measured body weight (−2.9 to −17.3 kg, 9 studies measured BMI (−1.1 to −5.1 kg/m2, 20 studies measured % body fat (−0.7 to −10.2%, and 22 studies measured fat mass (−0.9 to −14.9 kg. All studies found agreement between weight or BMI and body fat mass or body fat % decreases, though there were discrepancies in degree of significance between measures. Conclusions. Nearly all weight or BMI and body composition measures agreed. Since body fat is the most metabolically harmful tissue type, it may be a more meaningful measure of health change. Future studies should consider primarily measuring % body fat, rather than or in addition to weight or BMI.

    Dear, Peter; Jasanoff, Sheila

    2010-12-01

    The boundaries between the history of science and science and technology studies (STS) can be misleadingly drawn, to the detriment of both fields. This essay stresses their commonalities and potential for valuable synergy. The evolution of the two fields has been characterized by lively interchange and boundary crossing, with leading scholars functioning easily on both sides of the past/present divide. Disciplines, it is argued, are best regarded as training grounds for asking particular kinds of questions, using particular clusters of methods. Viewed in this way, history of science and STS are notable for their shared approaches to disciplining. The essay concludes with a concrete example--regulatory science--showing how a topic such as this can be productively studied with methods that contradict any alleged disciplinary divide between historical and contemporary studies of science.

    Full Text Available Water shortage and water pollution are important factors restricting sustainable social and economic development. As a typical coal resource-exhausted city and a node city of the South-to-North Water Transfer East Route Project in China, Zaozhuang City’s water resources management faces multiple constraints such as transformation of economic development, restriction of groundwater exploitation, and improvement of water environment. In this paper, we develop a linear optimization model by input–output analysis to study water resources management with the introduction of three advanced sewage treatment technologies for pollutant treatment and reclaimed water production. The simulation results showed that from 2014 to 2020, Zaozhuang City will realize an annual GDP growth rate of 7.1% with an annual chemical oxygen demand (COD emissions reduction rate of 5.5%. The proportion of primary industry, secondary industry, and tertiary industry would be adjusted to 5.6%, 40.8%, and 53.6%, respectively. The amount of reclaimed water supply could be increased by 91% and groundwater supply could be decreased by 6%. Based on the simulation, this model proposes a scientific reference on water resources management policies, including water environment control, water supply plan, and financial subsidy, to realize the sustainable development of economy and water resources usage.

    Full Text Available Abstract Background The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community. Methods Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women. Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older. Results Frequency of tooth brushing (OR = 3.98, having your own toothbrush (OR = 2.11, smoking (OR = 2.71 and bleeding gums (OR = 2.03 were significantly associated with number of retained teeth in males. Frequency of between-meal snacks was strongly associated with number of retained teeth in females (OR = 4.67. Having some hobbies (OR = 2.97, having a family dentist (OR = 2.34 and consulting a dentist as soon as symptoms occurred (OR = 1.74 were significantly associated with number of retained teeth in females. Factors that were significantly associated with tooth loss in both males and females included alcohol consumption (OR = 11.96, males, OR = 3.83, females, swollen gums (OR = 1.93, males, OR = 3.04, females and toothache (OR = 3.39, males, OR

    We report on the precision predictions for the e{sup +}e{sup -} → ZZγ process including Z-boson leptonic decays at the ILC in the standard model (SM). The calculation includes the full next-to-leading (NLO) electroweak (EW) corrections and high order initial state radiation (h.o. ISR) contributions. We find that the NLO EW corrections heavily suppress the LO cross section, and the h.o. ISR effects are notable near the threshold while become small in high energy region. We present the LO and the NLO EW+h.o. ISR corrected distributions of the transverse momenta of final Z-boson and photon as well as the Z-pair invariant mass, and we investigate the corresponding NLO EW and h.o. ISR relative corrections. We also study the leptonic decays of the final Z-boson pair by adopting the MadSpin method where the spin correlation effect is involved. We conclude that both the h.o. ISR effects and the NLO EW corrections are important in exploring the ZZγ production at the ILC. (orig.)

    Song, G.L.; Bursill, L.A.

    1997-06-01

    The structure of crystalline {alpha}-AlMnSi is examined by electron diffraction. Six distinct zone axes are examined, including both normal crystallographic and non-crystallographic zones axes, allowing the space group symmetry to be studied. Electron diffraction patterns characteristic of Pm3-bar were obtained for thicker specimens. However, for very thin specimens, as used for HRTEM imaging, the electron diffraction patterns were characteristic of Im3-bar space group symmetry. The structural basis of the Pm3-bar to Im3-bar transformation may be understood in terms of an analysis of the icosahedral structural elements located at the corners and body-centers of the cubic unit cell. A method for indexing the non-crystallographic zone axis diffraction patterns is described. An electron diffraction pattern of the 5-fold axis of the quasicrystalline phase i-AlMnSi is also included; this is compared with the experimental results and calculations for the [0{tau}1] axis of Pm3-bar and Im3-bar crystalline phases. 26 refs., 4 tabs., 7 figs.

    To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population. This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest-abdomen-pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDI{sub vol}) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure. The 75th percentiles of CTDI{sub vol} (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm, respectively; for chest, 15 mGy and 569 mGy cm; spine, 42 mGy and 888 mGy cm; cardiac, 7 mGy and 131 mGy cm for calcium score, and 61 mGy and 1,208 mGy cm for angiographic CT studies. High variability was present in the DLP of abdomen and CAP protocols, where multiphase examinations dominated (71 % and 73 % respectively): for abdomen, 18 mGy, with 555 and 920 mGy cm in abdomen and abdomen-pelvis acquisitions respectively; for CAP, 17 mGy, with 508, 850 and 1,200 mGy cm in abdomen, abdomen-pelvis and CAP acquisitions respectively. The results of this survey could help in the definition of updated diagnostic reference levels (DRL). (orig.)

  11. A Study on the Operation Strategy for Combined Accident including TLOFW accident

    It is difficult for operators to recognize the necessity of a feed-and-bleed (F-B) operation when the loss of coolant accident and failure of secondary side occur. An F-B operation directly cools down the reactor coolant system (RCS) using the primary cooling system when residual heat removal by the secondary cooling system is not available. The plant is not always necessary the F-B operation when the secondary side is failed. It is not necessary to initiate an F-B operation in the case of a medium or large break because these cases correspond to low RCS pressure sequences when the secondary side is failed. If the break size is too small to sufficiently decrease the RCS pressure, the F-B operation is necessary. Therefore, in the case of a combined accident including a secondary cooling system failure, the provision of clear information will play a critical role in the operators' decision to initiate an F-B operation. This study focuses on the how we establish the operation strategy for combined accident including the failure of secondary side in consideration of plant and operating conditions. Previous studies have usually focused on accidents involving a TLOFW accident. The plant conditions to make the operators confused seriously are usually the combined accident because the ORP only focuses on a single accident and FRP is less familiar with operators. The relationship between CET and PCT under various plant conditions is important to decide the limitation of initiating the F-B operation to prevent core damage.

    This study was carried out as a part of institutional activities of KAERI. Major research area are as follows; Future directions and effects for national nuclear R and D to be resulted from restructuring of electricity industry are studied. Comparative study was carried out between nuclear energy and other energy sources from the point of views of environmental effects by introducing life cycle assessment(LCA) method. Japanese trends of reestablishment of nuclear policy such as restructuring of nuclear administration system and long-term plan of development and use of nuclear energy are also investigated, and Russian nuclear development program and Germany trends for phase-out of nuclear electricity generation are also investigated. And trends of the demand and supply of energy in eastern asian countries in from the point of view of energy security and tension in the south china sea are analyzed and investigation of policy trends of Vietnam and Egypt for the development and use of nuclear energy for the promotion of nuclear cooperation with these countries are also carried out. Due to the lack of energy resources and high dependence of imported energy, higher priority should be placed on the use of localized energy supply technology such as nuclear power. In this connection, technological development should be strengthened positively in order to improve economy and safety of nuclear energy and proliferation resistance of nuclear fuel cycle and wide ranged use of radiation and radioisotopes and should be reflected in re-establishment of national comprehensive promotion plan of nuclear energy in progress.

    Full Text Available Background: Few clinical studies are found in the literature about patients hospitalized with a diagnosis of cutaneous drug eruption. Aims: To determine the clinical types of drug eruptions and their causative agents in a hospital-based population. Materials and Methods: This retrospective study was performed in the Dermatology Department of Haseki General Hospital. Through 1751 patients hospitalized in this department between 2002 and 2009, inpatients diagnosed as drug eruption were evaluated according to WHO causality definitions. 106 patients composed of probable and possible cases of cutaneous drug eruptions were included in this study. Results: Seventy one females and 35 males were evolved. Mean age was 44.03±15.14. Duration between drug intake and onset of reaction varied from 5 minutes to 3 months. The most common clinical type was urticaria and/or angioedema in 48.1% of the patients, followed by maculopapular rash in 13.2%, and drug rash with eosinophilia and systemic symptoms in 8.5%. Drugs most frequently associated with cutaneous drug eruptions were antimicrobial agents in 40.5% of the patients, followed by antipyretic/anti-inflammatory analgesics in 31.1%, and antiepileptics in 11.3%. Conclusion: Urticaria and/or angioedema and maculopapular rash comprised majority of the drug eruptions. Rare reactions such as acute generalized exanthematous pustulosis, sweet syndrome, oral ulceration were also found. Antimicrobial agents and antipyretic/anti-inflammatory analgesics were the most commonly implicated drugs. Infrequently reported adverse reactions to myorelaxant agents, newer cephalosporins and fluoroquinolones were also detected. We suppose that studies on drug eruptions should continue, because the pattern of consumption of drugs is changing in every country at different periods and many new drugs are introduced on the market continuously.

    Advances in synthetic biology have augmented the available toolkit of biomolecular modules, allowing engineering and manipulation of signaling in a variety of organisms, ranging in complexity from single bacteria and eukaryotic cells to multi-cellular systems. The richness of synthetic circuit outputs can be dramatically enhanced by sophisticated environmental control systems designed to precisely pattern spatial-temporally heterogeneous environmental stimuli controlling these circuits. Moreover, the performance of the synthetic modules and 'blocks' needed to assemble more complicated networks requires more complete characterization as a function of arbitrarily complex environmental inputs. Microfluidic technologies are poised to meet these needs through a variety of innovative designs capitalizing on the unique benefits of manipulating fluids on the micro-scales and nano-scales. This review discusses the utility of microfluidics for the study of synthetic circuits and highlights recent work in the area.

    Nightmares are intensive dreams with negative emotional tone. Frequent nightmares can pose a serious clinical problem and in 2001, Tanskanen et al. found that nightmares increase the risk of suicide. However, the dataset used by these authors included war veterans in whom nightmare frequency - and possibly also suicide risk - is elevated. Therefore, re-examination of the association between nightmares and suicide in these data is warranted. We investigated the relationship between nightmares and suicide both in the general population and war veterans in Finnish National FINRISK Study from the years 1972 to 2012, a dataset overlapping with the one used in the study by Tanskanen et al. Our data comprise 71,068 participants of whom 3139 are war veterans. Participants were followed from their survey participation until the end of 2014 or death. Suicides (N = 398) were identified from the National Causes of Death Register. Frequent nightmares increase the risk of suicide: The result of Tanskanen et al. holds even when war experiences are controlled for. Actually nightmares are not significantly associated with suicides among war veterans. These results support the role of nightmares as an independent risk factor for suicide instead of just being proxy for history of traumatic experiences.

    Conceptual Research Corporation, the Science of the Possible, has completed a two-year study of concepts and technologies for future airliners in the 180-passenger class. This NASA-funded contract was primarily focused on the ambitious goal of a 70 percent reduction in fuel consumption versus the market-dominating Boeing 737-800. The study is related to the N+3 contracts awarded in 2008 by NASA s Aeronautics Research Mission Directorate to teams led by Boeing, GE Aviation, MIT, and Northrop Grumman, but with more modest goals and funding. CRC s contract featured a predominant emphasis on propulsion and fuel consumption, but since fuel consumption depends upon air vehicle design as much as on propulsion technology, the study included notional vehicle design, analysis, and parametric studies. Other NASA goals including NOx and noise reduction are of long-standing interest but were not highlighted in this study, other than their inclusion in the propulsion system provided to CRC by NASA. The B-737-800 was used as a benchmark, parametric tool, and design point of departure. It was modeled in the RDS-Professional aircraft design software then subjected to extensive parametric variations of parasitic drag, drag-due-to-lift, specific fuel consumption, and unsized empty weight. These studies indicated that the goal of a 70 percent reduction in fuel consumption could be attained with roughly a 30 percent improvement in all four parameters. The results were then fit to a Response Surface and coded for ease of use in subsequent trade studies. Potential technologies to obtain such savings were identified and discussed. More than 16 advanced concept designs were then prepared, attempting to investigate almost every possible emerging concept for application to this class airliner. A preliminary assessment of these concepts was done based on their total wetted area after design normalization of trimmed maximum lift. This assessment points towards a Tailless Airliner concept which

    Full Text Available The ability of ferrous chelates including hairtail protein hydrolysates to prevent and reduce fatigue was studied in rats. After hydrolysis of hairtail surimi with papain, the hairtail protein hydrolysates (HPH were separated into three groups by range of relative molecular weight using ultrafiltration membrane separation. Hairtail proteins were then chelated with ferrous ions, and the antioxidant activity, the amino acid composition and chelation rate of the three kinds of ferrous chelates including hairtail protein hydrolysates (Fe-HPH were determined. Among the three groups, the Fe-HPH chelate showing the best conditions was selected for the anti-fatigue animal experiment. For it, experimental rats were randomly divided into seven groups. Group A was designated as the negative control group given distilled water. Group B, the positive control group, was given glutathione. Groups C, D and E were designated as the Fe-HPH chelate treatment groups and given low, medium, and high doses, respectively. Group F was designated as HPH hydrolysate treatment group, and Group G was designated as FeCl2 treatment group. The different diets were orally administered to rats for 20 days. After that time, rats were subjected to forced swimming training after 1 h of gavage. Rats given Fe-FPH chelate had higher haemoglobin regeneration efficiency (HRE, longer exhaustive swimming time and higher SOD activity. Additionally, Fe-FPH chelate was found to significantly decrease the malondialdehyde content, visibly enhance the GSH-Px activity in liver and reduce blood lactic acid of rats. Fe-HPH chelate revealed an anti-fatigue effect, similar to or better than the positive control substance and superior to HPH or Fe when provided alone.

    Highlights: • ESUR guideline that abdominal MR sequences are reserved for high-risk prostate cancer is tested. • Routine abdominal sequences are of low yield in prostate cancer MR staging. • Routine abdominal staging sequences frequently result in incidental findings. • Abdominal staging sequences should be reserved for high-risk prostate cancer cases. - Abstract: Objectives: Prostate cancer staging MR examinations commonly include abdominal sequences to assess for non-regional (common iliac or para-aortic) nodal metastasis. In our experience the diagnostic yield of this is limited, but incidental findings are frequent, often necessitating further investigations. The aim of this study is to assess the diagnostic utility of abdominal sequences in routine prostate cancer MR staging studies. Methods: Findings on abdominal sequences of consecutive MRI prostate studies performed for staging newly diagnosed prostate cancer between September 2011 and September 2013 were reviewed with respect to adenopathy and additional incidental findings. Results were correlated with Gleason grade and serum prostate-specific antigen (PSA) level in each case. Results: 355 MRI prostate examinations were reviewed. 4 (1.1%) showed enlarged non-regional lymph nodes. Incidental findings were found in 82(23.1%) cases, neccessitating further investigation in 45 (12.7%) cases. Enlarged non-regional nodes were associated with higher PSA level and Gleason grade (p = 0.007, p = 0.005 respectively). With a combined threshold of PSA > 20 ng/mL and/or Gleason grade ≥8 the sensitivity, specificity, PPV and NPV were 100, 60, 3 and 100% respectively for predicting the presence of non-regional adenopathy. Conclusions: Routine abdominal sequences are of very low yield in routine prostate cancer MR staging, frequently resulting in incidental findings requiring further work-up and should be reserved for high-risk cases. Our experience supports the use of an abdominal staging sequence in high

    Bipolar disorder affects many psychosocial and functional aspects, leading to a real social handicap and an alteration in quality of life. To evaluate bipolar patients' quality of life and to identify the risk factors responsible for a deterioration. Our cross-sectional study lasted for four months and included 104 bipolar patients treated at the psychiatry consultation of the university hospital in Mahdia. The data were collected through a questionnaire composed of 52 items exploring the general characteristics of subjects, the clinical and evolutional characteristics of bipolar disorder and providing information on the treatment. Quality of life was measured using the SF-36 (Short form) generic scale. A global average score was calculated and it was considered that quality of life was altered if the score was less than 66.7, according to the threshold value of Léan. Moreover, an average score was calculated for each dimension, thus permitting us to identify those most affected. We standardized initial average scores. The assessment of quality of life revealed a global average of 52.2 and an alteration in 78.8% of patients. The study of the dimensional average scores revealed that all dimensions were affected. The standardization also revealed deterioration in all dimensions, the mental component being particularly more affected than the physical component with respectively estimated scores of 31.7 and 40.5. The analytic approach concerned the relationship between qualitative and quantitative variables and the occurrence of an alteration in quality of life. For this effect, a bivariate study displayed a statistically significant correlation between the eight dimensions of the SF-36 and 8 variables. In order to take into account the relationships that link each variable to the others, and to avoid the bias of the bivariate study, a logistic regression analysis was performed. Only 4 variables with discriminating weight emerged from this analysis. According to the

    When delivered over a specific cortical site, TMS can temporarily disrupt the ongoing process in that area. This allows mapping of speech-related areas for preoperative evaluation purposes. We numerically explore the observed variability of TMS responses during a speech mapping experiment performed with a neuronavigation system. We selected four cases with very small perturbations in coil position and orientation. In one case (E) a naming error occurred, while in the other cases (NEA, B, C) the subject appointed the images as smoothly as without TMS. A realistic anisotropic head model was constructed of the subject from T1-weighted and diffusion-weighted MRI. The induced electric field distributions were computed, associated to the coil parameters retrieved from the neuronavigation system. Finally, the membrane potentials along relevant white matter fibre tracts, extracted from DTI-based tractography, were computed using a compartmental cable equation. While only minor differences could be noticed between the induced electric field distributions of the four cases, computing the corresponding membrane potentials revealed different subsets of tracts were activated. A single tract was activated for all coil positions. Another tract was only triggered for case E. NEA induced action potentials in 13 tracts, while NEB stimulated 11 tracts and NEC one. The calculated results are certainly sensitive to the coil specifications, demonstrating the observed variability in this study. However, even though a tract connecting Broca’s with Wernicke’s area is only triggered for the error case, further research is needed on other study cases and on refining the neural model with synapses and network connections. Case- and subject-specific modelling that includes both electromagnetic fields and neuronal activity enables demonstration of the variability in TMS experiments and can capture the interaction with complex neural networks.

    Two new 3,5-dihetarylsubstituted 1,2,4- oxadiazoles 8 a,b, including N-alkyl substituted carbazole and thiophene moieties, were synthesized as potential components of materials for organic electronics devices. Optical and electrochemical properties of all new compounds were investigated. On the basis of the experimental UV absorption data, the values of bandgap energies equal to 3.44 eV (8a) and 3.05 eV (8b) were determined. The values of their ionization potentials, HOMO levels (-5.62 eV for 8a, -5.46 eV - for 8b), as well as their electron affinity levels, LUMO levels (-2.2 eV for 8a, -2.4 eV - for 8b), were calculated from the results of electrochemical studies. The energy of the triplet excited states of 8 a,b was defined with the help of time-dependent density functional theory (TD-DFT), comprising 2.68 eV (8a) and 2.32 eV (8b), where the greatest value of this parameter was for the compound with a shorter conjugation chain.

    This study was designed to determine the optimum radiotherapy technique for internal mammary node (IMN) irradiation after breast-conserving surgery. We selected ten cases of early stage partial mastectomy for plan comparison. Five of the patients were treated to the right-side breast and the rest of the patients were treated to the left-side breast. For each case, four different treatment plans were made to irradiate the entire breast, IMNs and supraclavicular lymph nodes (SCLs). The four planning techniques include a standard tangential field (STF), wide tangential field (WTF), partially wide tangential field (PWT) and a photon-electron mixed field (PEM). We prescribed a dose of 50.4 Gy to the SCL field at a 3 cm depth and isocenter of the breast field. The dose distribution showed clear characteristics depending on the technique used. All of the techniques covered the breast tissue well. IMN coverage was also good, except for the STF, which was not intended to cover IMNs. For the cases of the left-side breasts, the volume of the heart that received more than 30 Gy was larger (in order) for the WTF, PWT, PEM and STF. For radiation pneumonitis normal tissue complication probability (NTCP), the PWT showed the best results followed by the STF. Despite the variety of patient body shapes, the PWT technique showed the best results for coverage of IMNs and for reducing the lung and heart dose.

    Synthesizing qualitative research is an important means of ensuring the needs, preferences, and experiences of patients are taken into account by service providers and policy makers, but the range of methods available can appear confusing. This study presents the methods for synthesizing qualitative research most used in health research to-date and, specifically those with a potential role in health technology assessment. To identify reviews conducted using the eight main methods for synthesizing qualitative studies, nine electronic databases were searched using key terms including meta-ethnography and synthesis. A summary table groups the identified reviews by their use of the eight methods, highlighting the methods used most generally and specifically in relation to health technology assessment topics. Although there is debate about how best to identify and quality appraise qualitative research for synthesis, 107 reviews were identified using one of the eight main methods. Four methods (meta-ethnography, meta-study, meta-summary, and thematic synthesis) have been most widely used and have a role within health technology assessment. Meta-ethnography is the leading method for synthesizing qualitative health research. Thematic synthesis is also useful for integrating qualitative and quantitative findings. Four other methods (critical interpretive synthesis, grounded theory synthesis, meta-interpretation, and cross-case analysis) have been under-used in health research and their potential in health technology assessments is currently under-developed. Synthesizing individual qualitative studies has becoming increasingly common in recent years. Although this is still an emerging research discipline such an approach is one means of promoting the patient-centeredness of health technology assessments.

    To describe and classify health technologies predicted in forecasting studies. A portrait describing health technologies predicted in 15 forecasting studies published between 1986 and 2010 that were identified in a previous systematic review. Health technologies are classified according to their type, purpose and clinical use; relating these to the original purpose and timing of the forecasting studies. All health-related technologies predicted in 15 forecasting studies identified in a previously published systematic review. Outcomes related to (1) each forecasting study including country, year, intention and forecasting methods used and (2) the predicted technologies including technology type, purpose, targeted clinical area and forecast timeframe. Of the 896 identified health-related technologies, 685 (76.5%) were health technologies with an explicit or implied health application and included in our study. Of these, 19.1% were diagnostic or imaging tests, 14.3% devices or biomaterials, 12.6% information technology systems, eHealth or mHealth and 12% drugs. The majority of the technologies were intended to treat or manage disease (38.1%) or diagnose or monitor disease (26.1%). The most frequent targeted clinical areas were infectious diseases followed by cancer, circulatory and nervous system disorders. The most frequent technology types were for: infectious diseases-prophylactic vaccines (45.8%), cancer-drugs (40%), circulatory disease-devices and biomaterials (26.3%), and diseases of the nervous system-equally devices and biomaterials (25%) and regenerative medicine (25%). The mean timeframe for forecasting was 11.6 years (range 0-33 years, median=10, SD=6.6). The forecasting timeframe significantly differed by technology type (p=0.002), the intent of the forecasting group (p<0.001) and the methods used (p<001). While description and classification of predicted health-related technologies is crucial in preparing healthcare systems for adopting new innovations

    A study to define potential benefits of advanced technology propeller for 1985-1990 STAT commuter airplanes was completed. Two baselines, a Convair, 30 passenger, 0.47 Mach number airplane and a Lockheed, 50 passenger, 0.70 Mach number airplane, were selected from NASA-Ames sponsored airframe contracts. Parametric performance, noise level, weight and cost trends for propellers with varying number of blades, activity factor, camber and diameter incorporating blade sweep, tip proplets, advanced composite materials, advanced airfoils, advanced prevision synchrophasing and counter-rotation are presented. The resulting DOC, fuel burned, empty weight and acquisition cost benefits are presented for resizings of the two baseline airplanes. Six-bladed propeller having advanced composite blades, advanced airfoils, tip proplets and advanced prevision synchrophasers provided the maximum DOC improvements for both airplanes. DOC and fuel burned were reduced by 8.3% and 17.0% respectively for the Convair airplane and by 24.9% and 41.2% respectively for the Lockheed airplane. The larger reductions arose from a baseline definition with very heavy fuselage acoustic treatment. An alternate baseline, with a cabin noise 13dB in excess of the objective, was also studied.

    Lead oxide (PbO), which plays the key roles in a range of research fields, has received a great deal of attention. Owing to the large density of electronic states and heavy atom Pb including in PbO, the excited states of the molecule have not been well studied. In this work, high level multireference configuration interaction calculations on the low-lying states of PbO have been carried out by utilizing the relativistic effective core potential. The effects of the core-valence correlation correction, the Davidson modification, and the spin–orbital coupling on the electronic structure of the PbO molecule are estimated. The potential energy curves of 18Λ-S states correlated to the lowest dissociation limit (Pb (3Pg)+O(3Pg)) are reported. The calculated spectroscopic parameters of the electronic states below 30000 cm−1, for instance, X1Σ+, 13Σ+, and 13Σ−, and their spin–orbit coupling interaction, are compared with the experimental results, and good agreements are derived. The dipole moments of the 18Λ-S states are computed with the configuration interaction method, and the calculated dipole moments of X1Σ+and 13Σ+are consistent with the previous experimental results. The transition dipole moments from 11Π, 21Π, and 21Σ+to X1Σ+and other singlet excited states are estimated. The radiative lifetime of several low-lying vibrational levels of 11Π, 21Π, and 21Σ+states are evaluated.

    Systematic reviews within the Cochrane Effective Practice and Organisation of Care Group (EPOC) can include both randomized and nonrandomized study designs. We explored how many EPOC reviews consider and identify nonrandomized studies, and whether the proportion of nonrandomized studies identified is linked to the review topic. We recorded the study designs considered in 65 EPOC reviews. For reviews that considered nonrandomized studies, we calculated the proportion of identified studies that were nonrandomized and explored whether there were differences in the proportion of nonrandomized studies according to the review topic. Fifty-one (78.5%) reviews considered nonrandomized studies. Forty-six of these reviews found nonrandomized studies, but the proportion varied a great deal (median, 33%; interquartile range, 25--50%). Reviews of health care delivery interventions had lower proportions of nonrandomized studies than those of financial and governance interventions. Most EPOC reviews consider nonrandomized studies, but the degree to which they find them varies. As nonrandomized studies are believed to be at higher risk of bias and their inclusion entails a considerable effort, review authors should consider whether the benefits justify the inclusion of these designs. Research should explore whether it is more useful to consider nonrandomized studies in reviews of some intervention types than others. Copyright © 2013 Elsevier Inc. All rights reserved.

    Genome-wide association studies (GWAS), in which thousands of single-nucleotide polymorphisms (SNPs) spanning the genome are genotyped in individuals who are phenotypically well characterized, -currently represent the most popular strategy for identifying gene regions associated with common -diseases and related quantitative traits. Improvements in technology and throughput capability, development of powerful statistical tools, and more widespread acceptance of pooling-based genotyping approaches have led to greater utilization of GWAS in human genetics research. However, important considerations for optimal experimental design, including selection of the most appropriate genotyping platform, can enhance the utility of the approach even further. This chapter reviews experimental and technological issues that may affect the success of GWAS findings and proposes strategies for developing the most comprehensive, logical, and cost-effective approaches for genotyping given the population of interest.

    Full Text Available In the article divorce the concepts of engineering and technology. Designated four stages of technological development: the fi rst phase — “pilot technique”, it is characterized by magical conceptualization, the second — engineering (rational conceptualization, third design, fourth technology. For technical equipment is characterized by four features: technology is the artifacts, the technique can be considered as a “social body” of a person or society, technology is a useful way to use the forces of nature, and fi nally, the mediation in the form of tools, machines, and material environment that allows you to implement the ideas of man. It is argued that the conceptualization of technology is the essential characteristic of the concept. If you write, for example, about the technology of the Neolithic age or era of construction of the Egyptian pyramids, then we are talking about retrospective interpretation, from the point of view of modern understanding of technology. It’s not useless, for example, to determine preconditions of formation technology, but in terms of thinking creates problems and contradictions. The author argues that technology develops in the second half of the eighteenth century as a new reality, which describes the industrial activities in language operations and their conditions of division of labor and management. At the same time, technology is being characterized by the installation of quality, savings, standardization, and rational description of the production processes, their optimization for the training of new technologists.

    Three patients with slowly progressive fluent aphasia are reported. One of the patients presented with memory disturbance. They were characterized clinically by having selective deficits in vocabulary, which resulted in impairment of confrontation naming, and auditory comprehension. MRI showed an atrophy not only in the left temporal lobe (including the superior, middle and inferior temporal gyri), hippocampus, parahippocampual gyrus, and fusiform gyrus, but also in the left parietal lobe. I-123 IMP SPECT and F-18 FDG PET were used to determine regional cerebral blood flow and regional cerebral metabolic rate, respectively. In addition to the decreased tracer uptake in the left temporal and/or parietal lobe, a decreased uptake was seen in the bilateral basal ganglia, the inner side of the temporal lobe (including the bilateral hippocampus), the right anterior temporal lobe, and the left thalamus. These findings may deny the previous thought that lesions are localized in slowly progressive fluent aphasia. Furthermore, noticeable difficulty in naming, i.e., patients unable to recognize the right answer, are considered attributable to widespread lesions from the whole left temporal lobe, including the hippocampus, to the right temporal lobe.

    In the health field, technologies of care relations are in the scope of the worker-user encounter, implying intersubjectivity with the development of relationships between subjects, resulting in action. Evaluation studies synthesize knowledge produced on the consequences of using these technologies for society. This anthropological study aims to understand the perception of the elderly regarding the resolution capability and effectiveness of the acts produced in health care relationships in the context of the Family Health Strategy (ESF). The group studied consisted of 57 elderly residents in Bambui, State of Minas Gerais, Brazil. The model of signs, meanings and actions was used for collecting and analyzing data and the semi-structured interview was applied as a research technique. Elderly individuals assess resolution capability and effectiveness of the acts of care in the ESF as negative, with relation to the quality of user and professional interaction. The ESF is not effective and the desired change in the health care model has not occurred in practice. It repeats the centrality of the medical-drug-procedure model that treats the disease rather than the patient, perceiving old age as a disease and illness as being related to aging.

  20. Study of Power Flow Algorithm of AC/DC Distribution System including VSC-MTDC

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available In recent years, distributed generation and a large number of sensitive AC and DC loads have been connected to distribution networks, which introduce a series of challenges to distribution network operators (DNOs. In addition, the advantages of DC distribution networks, such as the energy conservation and emission reduction, mean that the voltage source converter based multi-terminal direct current (VSC-MTDC for AC/DC distribution systems demonstrates a great potential, hence drawing growing research interest. In this paper, considering losses of the reactor, the filter and the converter, a mathematical model of VSC-HVDC for the load flow analysis is derived. An AC/DC distribution network architecture has been built, based on which the differences in modified equations of the VSC-MTDC-based network under different control modes are analyzed. In addition, corresponding interface functions under five control modes are provided, and a back/forward iterative algorithm which is applied to power flow calculation of the AC/DC distribution system including VSC-MTDC is proposed. Finally, by calculating the power flow of the modified IEEE14 AC/DC distribution network, the efficiency and validity of the model and algorithm are evaluated. With various distributed generations connected to the network at appropriate locations, power flow results show that network losses and utilization of transmission networks are effectively reduced.

    Modak, Soumita; Chattopadhyay, Asis Kumar

    2016-01-01

    Formation mechanism of present day population of elliptical galaxies have been revisited in the context of hierarchical cosmological models accompanied by accretion and minor mergers through cross correlation function including spatial effect. The present work investigates the formation and evolution of several components of nearby massive early type galaxies (ETGs) through cross-correlation in the spatial coordinates, right ascension and declination (RA, DEC) and mass-size parameter space with high redshift $(0.5\\leq z\\leq2.7)$ ETGs. It is found that innermost components of nearby ETGs are highly correlated with ETGs in the redshift range $(2\\leq z\\leq2.7)$ known as 'red nuggets'. The intermediate and outermost parts have moderate correlations with ETGs in the redshift range $(0.5\\leq z\\leq0.75)$. The quantitative measures are highly consistent with the two phase formation scenario of massive nearby early type galaxies as suggested by various authors and resolves the conflict raised in a previous work sugges...

  2. Extensive ab initio study of the electronic states of BSe radical including spin-orbit coupling

    2016-06-01

    The internally contracted multi-reference configuration interaction method (MRCI) with Davidson modification and the Douglas-Kroll scalar relativistic correction has been used to calculate the BSe molecule at the level of aug-cc-pV5Z basis set. The calculated electronic states, including 9 doublet and 6 quartet Λ-S states, are correlated to the dissociation limit of B(2Pu) + Se(3Pg) and B(2Pu) + Se(1Dg). The Spin-orbit coupling (SOC) interaction is taken into account via the state interaction approach with the full Breit-Pauli Hamiltonian operator, which causes the entire 15 Λ-S states to split into 32 Ω states. This is the first time that the spin-orbit coupling calculation has been carried out on BSe. The potential energy curves of the Λ-S and Ω electronic states are depicted with the aid of the avoided crossing rule between electronic states of the same symmetry. The spectroscopic constants of the bound Λ-S and Ω states were determined, which are in good agreement with the experimental data. The transition dipole moments (TDMs) and the Franck-Condon factors (FCs) of the transitions from the low-lying bound Ω states A2Π(I)3/2, B2Π(I)1/2 and C2Δ(I)3/2 to the ground state X2Σ+1/2 have also been presented. Based on the previous calculations, the radiative lifetimes of the A2Π(I)3/2, B2Π(I)1/2 and C2Δ(I)3/2 were evaluated.

    2003-01-01

    We study the effect of strong magnetic fields on the structure of neutronstar. We find that if the interior field is on the same order as the surface fieldcurrently observed, then the influences of the field on the star's mass and radius arenegligible; if the field is as large as that estimated from the scalar virial theorem,then considerable effects will be induced. The maximum mass of the star will beincreased substantially while the central density is greatly reduced. The radius ofa magnetic star can be larger by about 10% ~ 20% than a nonmagnetic star of thesame mass.

    Full Text Available We expand the completeness study instigated in [J. Math. Phys. 50 (2009, 103516, 29 pages] which found all 2×2 Lax pairs with non-zero, separable terms in each entry of each Lax matrix, along with the most general nonlinear systems that can be associated with them. Here we allow some of the terms within the Lax matrices to be zero. We cover all possible Lax pairs of this type and find a new third order equation that can be reduced to special cases of the non-autonomous lattice KdV and lattice modified KdV equations among others.

  6. Alternative oxidizers for strip coal mine blasting agents. [Including study of possible substitutes; 53 references

    Energy Technology Data Exchange (ETDEWEB)

    Sudweeks, W.B.; Collins, T.K.

    1979-03-14

    Since ammonium nitrate manufacture is dependent on natural gas, a shortage in natural gas could lead to a critical shortage in coal by limiting the availability of ammonium nitrate for blasting. The purpose of this study was to assess the future availability of ammonium nitrate and to evaluate the potential of alternative oxidizers not dependent upon natural gas for use in blasting agents. Increased storage capacities and rapidly increasing levels of relativey cheap imported ammonia appear to ensure the availability of adequate levels of ammonium nitrate in the near future. In the longer time frame, rising energy costs have increased the potential for basing ammonia production on alternative sources of hydrogen as well as obtaining natural gas from relatively unlimited unconventional sources. While still somewhat uncertain, such unconventional sources appear to have sufficient potential to ensure the availability of ammonium nitrate even long term. However, there are several oxidizers that could be considered as possible replacements for ammonium nitrate if needed. After a critical evaluation two possible alternatives are recommended for further study: the use of sodium nitrate as a partial replacement and the development of a new type of blasting agent based upon water as the main oxidizer.

    2015-01-01

    Objective The number of analyzed outcome variables is important in the statistical analysis and interpretation of research findings. This study investigated published papers in the field of environmental health studies. We aimed to examine whether differences in the number of reported outcome variables exist between papers with non-significant findings compared to those with significant findings. Articles on the maternal exposure to mercury and child development were used as examples. Methods Articles published between 1995 and 2013 focusing on the relationships between maternal exposure to mercury and child development were collected from Medline and Scopus. Results Of 87 extracted papers, 73 used statistical significance testing and 38 (43.7%) of these reported ‘non-significant’ (P>0.05) findings. The median number of child development outcome variables in papers reporting ‘significant’ (n=35) and ‘non-significant’ (n=38) results was 4 versus 7, respectively (Mann-Whitney test P-value=0.014). An elevated number of outcome variables was especially found in papers reporting non-significant associations between maternal mercury and outcomes when mercury was the only analyzed exposure variable. Conclusion Authors often report analyzed health outcome variables based on their P-values rather than on stated primary research questions. Such a practice probably skews the research evidence.

  8. Comprehensive study in the inhibitory effect of berberine on gene transcription, including TATA box.

    Directory of Open Access Journals (Sweden)

    Yugang Wang

    Full Text Available Berberine (BBR is an established natural DNA intercalator with numerous pharmacological functions. However, currently there are neither detailed reports concerning the distribution of this alkaloid in living cells nor reports concerning the relationship between BBR's association with DNA and the function of DNA. Here we report that the distribution of BBR within the nucleus can be observed 30 minutes after drug administration, and that the content of berberine in the nucleus peaks at around 4 µmol, which is twelve hours after drug administration. The spatial conformation of DNA and chromatin was altered immediately after their association with BBR. Moreover, this association can effectively suppress the transcription of DNA in living cell systems and cell-free systems. Electrophoretic mobility shift assays (EMSA demonstrated further that BBR can inhibit the association between the TATA binding protein (TBP and the TATA box in the promoter, and this finding was also attained in living cells by chromatin immunoprecipitation (ChIP. Based on results from this study, we hypothesize that berberine can suppress the transcription of DNA in living cell systems, especially suppressing the association between TBP and the TATA box by binding with DNA and, thus, inhibiting TATA box-dependent gene expression in a non-specific way. This novel study has significantly expanded the sphere of knowledge concerning berberine's pharmacological effects, beginning at its paramount initial interaction with the TATA box.

    Amphiphilic molecules which have a biological effect on specific membrane proteins, could also affect lipid bilayer properties possibly resulting in a modulation of the overall membrane behavior. In light of this consideration, it is important to study the possible effects of amphiphilic molecule of pharmacological interest on model systems which recapitulate some of the main properties of the biological plasma membranes. In this work we studied the effect of a neurosteroid, Allopregnanolone (3α,5α-tetrahydroprogesterone or Allo), on a model bilayer composed by the ternary lipid mixture DOPC/bSM/chol. We chose ternary mixtures which present, at room temperature, a phase coexistence of liquid ordered (Lo) and liquid disordered (Ld) domains and which reside near to a critical point. We found that Allo, which is able to strongly partition in the lipid bilayer, induces a marked increase in the bilayer area and modifies the relative proportion of the two phases favoring the Ld phase. We also found that the neurosteroid shifts the miscibility temperature to higher values in a way similarly to what happens when the cholesterol concentration is decreased. Interestingly, an isoform of Allo, isoAllopregnanolone (3β,5α-tetrahydroprogesterone or isoAllo), known to inhibit the effects of Allo on GABAA receptors, has an opposite effect on the bilayer properties.

    2013-11-01

    The geometric and electronic structure of donor-acceptor complexes of TCNE with aniline, o-, m- and p- aminopyridines and pyridine has been studied in gas phase and in solution using CC2, TDDFT and CIS methods. Concerning interaction energy between particular donor and TCNE acceptor it is fairly described by both CC2 (MP2) and DFT-D approaches. Transition energies in gas phase calculated by CC2 approach are in good agreement with available experimental data for aniline. TDDFT calculations with LC-BLYP functional (with standard value of range separation factor μ = 0.47) gives transition energies too high although not as high as CIS. The red solvent shifts, calculated by PCM model with CIS method are qualitative correct, but error in the range of 0.1-0.2 eV should be expected.

    2015-05-01

    Using the ab initio methods for solving the Bethe-Salpeter equation on the basis of the FPLAPW method, optical properties of crystalline phenanthrene were calculated, in a comparison to its isomer, anthracene. It was found that despite the similarity of the structural, electronic, and the overall optical properties in a 40 eV energy range, phenanthrene and anthracene show significant differences in their optical spectra in the energy range below band gaps. Phenanthrene has two spin singlet excitonic features whereas anthracene shows one. The singlet and the lowest triplet binding energies of phenanthrene were found to be larger than anthracene. In this study, in addition, a comparison has been made between the optical spectra in RPA and the existing experimental data.

    Feyissa, Frezer Assefa

    In microelectronics soldering to Cu pad lead to formation of two intermetallic structures in the solder -pad interface. The growth of these layers is accompanied by microscopic voids that usually cause reliability concern in the industry. Therefore it is important to understand factors that contribute for the growth of IMC using various combination of reflow time, Sn thickness and aging temperature. Systematic study was conducted on Cu-Sn system to investigate the formation and growth of intermetallic compound (IMC) as well as voiding evolution for different solder thicknesses. The growth of the Cu6Sn5 IMC layer was found to be increasing as the Sn thicknesses increase after reflow while the Cu3Sn layer were decreasing under same conditions. Also after reflow and aging more voiding were shown to occur in the thin solder than thicker one.

    2016-12-01

    Full Text Available Adoption of new technologies is a process that involves technological learning and penetration of new products into the market. Within the process of new technologies adoption, government usually intervened by providing incentives, in order to support the technology adoption to be succeed. This paper examines the effectiveness of incentives for the sustainability of reverse osmosis (RO membrane technology adoption. The study conducted through single case study on SWRO installation in Mandangin Island, East Java, Indonesia. Results of case study indentify the existence of government incentive in the form of direct subsidies to decrease the price of clean water. Although successful in reducing the price of water, but effectiveness of the subsidy on the sustainability of SWRO is still low, which is operates only 30% in a year. Further analysis shows that these subsidies actually be counter-productive to the sustainability of SWRO installation.

    Directory of Open Access Journals (Sweden)

    José L. VÁZQUEZ

    2006-06-01

    Full Text Available As a consequence of continuous adaptation of public institutions to requirements of framing where they perform day by day, Public Management and Administration is behaving once and again as a “reinvented” discipline, aiming a new kind of rational, innovative public entities that focus their activities towards an effective achievement of their intended results and benefits. Concepts such as those of “efficiency”, “effectiveness”, “responsibility”, “organizational culture”, etc. are now not only applied to business disciplines, but also to Public Management and Administration. At this point, Marketing has proved to be an useful subject in PMA curricula, not only being in demand by students and syllabi designers, but also by experts in the public field. However, applying marketing techniques and procedures in the same way as used in private business is clearly nonsense. We must consider a proper “public marketing” or “public sector marketing” development. In this paper we debate on these issues, as well as present an overview into the situation of Spanish public universities offering PMA studies, just when they are facing the Bologna adaptation requirements. As a conclusion, some comments for reflection are suggested.

  17. Plasma-water systems studied with optical diagnostics including sum-frequency generation spectroscopy

    Ito, Tsuyohito

    2016-09-01

    Recently, various applications of plasma-water systems have been reported, such as materials synthesis, agricultural applications, and medical treatments. As one of basic studies of such systems, we are investigating water surface structure influenced by a plasma via vibrational sum-frequency generation spectroscopy. Vibrational sum-frequency generation spectroscopy is known to be an interfacially active diagnostic technique, as such process occurs in noncentrosymmetric medium. Visible and wavenumber-tunable infrared beams are simultaneously irradiated to the interface. The interfacial water has ice-like ( 3200 cm-1), liquid-like ( 3400 cm-1), and free OH (3700 cm-1) structures (assignment of the ice-like structure still remains contentious), and the intensity of the signal becomes stronger when the tunable infrared beam resonates with a vibration of the structures. The results indicate that with generating air dielectric barrier discharges for supplying reactive species to the water surface, all investigated signals originating from the above-mentioned three structures decrease. Furthermore, the signal strengths are recovered after terminating the plasma generation. We currently believe that the surface density of the reactive species should be high when they are found at the water surface. Details on the experimental results of the sum-frequency generation spectroscopy, as well as other spectroscopic results of plasma-water systems, will be presented at the conference.

    Künzel, Frank; Rebel-Bauder, Barbara; Kassl, Christine; Leschnik, Michael; Url, Angelika

    2017-02-01

    Objectives Despite comprehensive diagnostics, the aetiology of meningoencephalitis (ME) in cats often remains undetermined. As a result of recently published surveys, Encephalitozoon cuniculi has gained growing importance in cats not only with ocular disorders, but also with central nervous system disease. Therefore, it was hypothesised that E cuniculi may be an underestimated pathogen in the development of feline non-suppurative and/or granulomatous ME. Methods As a first step, histopathological sections of the brain of cats with encephalopathy were retrospectively reviewed to identify cases of granulomatous ME. In a second step, an immunohistochemical screening for detection of E cuniculi was performed in cases with ME of unknown origin. Results In 59/89 (66.3%) cats with ME, an aetiologically relevant pathogen was detected. Forty-three of 89 (48.3%) cats had a diagnosis of feline infectious peritonitis. In 14/89 (15.7%) cats, protozoan cysts were identified and infection with Toxoplasma gondii was confirmed by immunohistochemistry (IHC) in all cases. In 2/89 (2.3%) cats with granulomatous ME, fungal organisms were identified. Thirty of 89 (33.7%) cats with ME of unknown origin that underwent IHC for the detection of E cuniculi remained negative. Conclusions and relevance The results of this study suggest that E cuniculi is unlikely to be directly associated with (non-suppurative and/or granulomatous) ME in cats in Austria.

    Full Text Available A saxitoxin (STX proficiency test (PT was organized as part of the Establishment of Quality Assurance for the Detection of Biological Toxins of Potential Bioterrorism Risk (EQuATox project. The aim of this PT was to provide an evaluation of existing methods and the European laboratories’ capabilities for the analysis of STX and some of its analogues in real samples. Homogenized mussel material and algal cell materials containing paralytic shellfish poisoning (PSP toxins were produced as reference sample matrices. The reference material was characterized using various analytical methods. Acidified algal extract samples at two concentration levels were prepared from a bulk culture of PSP toxins producing dinoflagellate Alexandrium ostenfeldii. The homogeneity and stability of the prepared PT samples were studied and found to be fit-for-purpose. Thereafter, eight STX PT samples were sent to ten participating laboratories from eight countries. The PT offered the participating laboratories the possibility to assess their performance regarding the qualitative and quantitative detection of PSP toxins. Various techniques such as official Association of Official Analytical Chemists (AOAC methods, immunoassays, and liquid chromatography-mass spectrometry were used for sample analyses.

    2007-11-01

    This paper summarized the nowadays positioning technologies, such as absolute positioning methods and relative positioning methods, indoor positioning and outdoor positioning, active positioning and passive positioning. Global Navigation Satellite System (GNSS) technologies were introduced as the omnipresent out-door positioning technologies, including GPS, GLONASS, Galileo and BD-1/2. After analysis of the shortcomings of GNSS, indoor positioning technologies were discussed and compared, including A-GPS, Cellular network, Infrared, Electromagnetism, Computer Vision Cognition, Embedded Pressure Sensor, Ultrasonic, RFID (Radio Frequency IDentification), Bluetooth, WLAN etc..

    In order to investigate features of cognitive impairment in idiopathic Parkinson's disease (PD) and suitable methods for the cognitive evaluation of patients with PD, 23 PD patients and 15 normal control subjects were studied using neuropsychological tests and auditory event-related potential (ERP). The two groups did not differ from each other in age or education. Clinical severity of the patients based on Hoehn & Yahr's staging ranged from stage I to IV: 7 patients at stage I, 8 at stage II, 7 at stage III and 1 at stage IV. All patients achieved the Mini-Mental State test (MMS) scores of 24 or greater, and none of the patients showed middle or serious grade of dementia based on the Diagnostic and Statistical Manual of Mental Disorders-Third edition-Revised (DSM-III-R). All patients and controls underwent MMS, the Hasegawa's Dementia Screening Scale (HDS), the Wechsler Adult Intelligence Scale-Revised (WAIS-R), the Raven's coloured progressive matrices (RCPM), The Wisconsin Card Sorting Test (WCST) and the Benton Visual Retention Test (BVRT). Auditory ERPs by standard oddball paradigm (two-choice reaction time task) were elicited (band-pass 0.1-50 Hz) from Cz electrode sites on all subjects with a random series of binaural 1,000 (standard; 80%) or 2,000 (target; 20%) Hz tones presented every 2 sec at 70 dB SPL. In RCPM, N100 peak latencies of ERP (target and standard), performance-IQ of WAIS-R (especially block design and digit symbol subtests) and in error scores of BVRT there were striking differences between the two groups (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Eighty-three men were randomised to the NLPI plus usual care or usual care alone (UCA (42 NLPI and 41 UCA; the NLPI plus usual care was delivered in the primary-care setting (the intervention and included an initial face-to-face consultation with a trained nurse, with follow-up tailored to individual needs. The study afforded the opportunity to undertake a short-term within pilot analysis. The primary outcome measure for the economic evaluation was quality of life, as measured by the EuroQol five dimensions questionnaire (EQ-5D (EQ-5D-5L instrument. Costs (£2014 assessed included health-service resource use, out-of-pocket expenses and losses from inability to undertake usual activities.ResultsTotal and incremental costs varied across the different scenarios assessed, with mean cost differences ranging from £173 to £346; incremental effect, as measured by the change in utility scores over the duration of follow-up, exhibited wide confidence intervals highlighting inconclusive effectiveness (95% CI: -0.0226; 0.0438. The cost per patient of delivery of the intervention would be reduced if rolled out to a larger patient cohort.ConclusionsThe NLPI is potentially cost saving depending on the scale of delivery; however, the results presented are not considered generalisable.

    This report represents the preliminary effort in studying the significance of recognition for innovators of spinoff technologies. The purpose of this initial year's effort in this area was to gather preliminary data and define the direction for the remainder of the research. This report focuses on the most recent recipients of the Hall of Fame Award, the developers of liquid-cooled garments. Liquid-cooled garments technology and its spinoffs were used as a case study to define and explore the factors involved in technology transfer and to consider the possible incentives in developing commercial applications including the Hall of Fame Award. Through interviews, views of award recipients were obtained on factors encouraging spinoffs as well as impediments to spinoffs. The researchers observed complex inter-relationships among the significant entities (government, individuals, large and small business), the importance of people, the importance of resource availability, and the significance of intrinsic motivation; drew preliminary conclusions pertaining to the direct and indirect influence of recognition like the Hall of Fame Award; and planned the direction for next year's follow-on research.

    Technological characterization of pre-Hispanic gold metallurgy has still a wide deficit of analytical data. A set of 103 pieces from the so called "Quimbaya's treasure" (QT) and the "Costa Rica collection" (CRC) of the Museo de America of Madrid were submitted to IBA analysis (PIXE and RBS) at the CMAM in three phases and the metal composition was determined. Only in a limited number of cases, due to the dramatic erosion of the gilded layer, produced by abrasive cleaning methods applied after the discovery and before the seventies, it was possible to determine also the sequence of layers, which gives information on the manufacture technology and the type and purity of the metals. PIXE results are reported and discussed. Data show that the CRC objects have very high gold levels (>80% in weight) while the QT have a more variable composition with significant Cu levels associated to the so called Tumbaga-alloy. In the cases where polishing had a tolerable effect, PIXE (and RBS), point to depletion gilding as a standard finishing process in the Costa Rica production, resulting in a gold rich surface alloy, while the variable composition of the QT objects may well be linked to deliberate colour choice.

    The National Institutes of Health and other federal agencies are considering initiating a cohort study of 500,000 people, including 120,000 children, to measure genetic and environmental influences on common diseases. A community engagement pilot study was conducted to identify public attitudes and concerns about the proposed cohort study, including the ethics of involving children. The pilot included 15 focus groups where the inclusion of children in the proposed cohort study was discussed. Focus groups, conducted in six cities, included 141 adults of different ages, incomes, genders, ethnicities, and races. Many of the concerns expressed by participants mirrored those addressed in pediatric research guidelines. These concerns included minimizing children's fear, pain, and burdens; whether to include young children; and how to obtain children's assent. There was little agreement about which children can assent. Some voiced concern about children's privacy, but most expected that parents would have access to children's study results. Some believed children would not benefit from participating, while others identified personal and societal benefits that might accrue. A few people believed that children's participation would not advance the study's goals. To successfully include children, proposed cohort study would need to address children's changing capabilities and rights as they grow and reach the age of consent.

    The ship recycling industry is growing rapidly. It is estimated that the International Maritime Organization's (IMO) decision to phase-out single hull tankers by 2015 will result in hundreds of ships requiring disposal. At present, the ship recycling industry is predominantly based in South Asia. Due to the bad practice of current scrapping procedure, the paper will highlight the harm occurring to health, safety and environment. The efforts of the Marine Environment Protection Committee (MEPC) which led to the signing of the Hong Kong International Convention are also reviewed. The criteria and standards required to reduce the risk and damage to the environment are discussed and a proposed plan for the safe scrapping of ships is then presented. A technological and economic study for the ship recycling in Egypt is carried out as a case study. This includes the ship recycling facility size and layout. The equipment and staff required to operate the facility are also evaluated. A cost analysis is then carried out. This includes site development, human resources, machineries and equipment. A fuzzy logic approach is used to assess the benefits of the ship breaking yard. The use of the fuzzy logic approach is found suitable to make decisions for the ship breaking industry. Based on given constraints, the proposed model has proved capable of assessing the profit and the internal rate of return.

  14. Cost studies of thermally enhanced in situ soil remediation technologies

    Energy Technology Data Exchange (ETDEWEB)

    Bremser, J.; Booth, S.R.

    1996-05-01

    This report describes five thermally enhanced technologies that may be used to remediate contaminated soil and water resources. The standard methods of treating these contaminated areas are Soil Vapor Extraction (SVE), Excavate & Treat (E&T), and Pump & Treat (P&T). Depending on the conditions at a given site, one or more of these conventional alternatives may be employed; however, several new thermally enhanced technologies for soil decontamination are emerging. These technologies are still in demonstration programs which generally are showing great success at achieving the expected remediation results. The cost savings reported in this work assume that the technologies will ultimately perform as anticipated by their developers in a normal environmental restoration work environment. The five technologies analyzed in this report are Low Frequency Heating (LF or Ohmic, both 3 and 6 phase AC), Dynamic Underground Stripping (DUS), Radio Frequency Heating (RF), Radio Frequency Heating using Dipole Antennae (RFD), and Thermally Enhanced Vapor Extraction System (TEVES). In all of these technologies the introduction of heat to the formation raises vapor pressures accelerating contaminant evaporation rates and increases soil permeability raising diffusion rates of contaminants. The physical process enhancements resulting from temperature elevations permit a greater percentage of volatile organic compound (VOC) or semi- volatile organic compound (SVOC) contaminants to be driven out of the soils for treatment or capture in a much shorter time period. This report presents the results of cost-comparative studies between these new thermally enhanced technologies and the conventional technologies, as applied to five specific scenarios.

    This paper addresses the mathematical relation on a set of periods and temporal indexing constructions as well as their applications. First we introduce two concepts, i.e. the temporal connection and temporal inclusion, which are equivalence relation and preorder relation respectively. Second, by studying some basic topics such as the division of "large" equivalence classes and the overlaps of preorder relational sets, we propose a temporal data index model (TDIM) with a tree-structure consisting of a root node, equivalence class nodes and linearly ordered branch nodes. Third, we study algorithms for the temporal querying and incremental updating as well as dynamical management within the framework of TDIM. Based on a proper mathematical supporting, TDIM can be applied to researching some significant practical cases such as temporal relational and temporal XML data and so on.

    The Cogeneration Technology Alternatives Study (CTAS), a program undertaken to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the 1985-2000 time period, is described, and preliminary results are presented. Two cogeneration options are included in the analysis: a topping application, in which fuel is input to the energy conversion system which generates electricity and waste heat from the conversion system is used to provide heat to the process, and a bottoming application, in which fuel is burned to provide high temperature process heat and waste heat from the process is used as thermal input to the energy conversion system which generates energy. Steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics are examined. Expected plant level energy savings, annual energy cost savings, and other results of the economic analysis are given, and the sensitivity of these results to the assumptions concerning fuel prices, price of purchased electricity and the potential effects of regional energy use characteristics is discussed.

    2011-03-01

    Most known human teratogens are associated with a unique or characteristic pattern of major and minor malformations and this pattern helps to establish the causal link between the teratogenic exposure and the outcome. Although traditional case-control and cohort study designs can help identify potential teratogens, there is an important role for small cohort studies that include a dysmorphological examination of exposed and unexposed infants for minor structural defects. In combination with other study design approaches, the small cohort study with a specialized physical examination fulfills a necessary function in screening for new potential teratogens and can help to better delineate the spectrum and magnitude of risk for known teratogens.

  9. Study on precision cutting technology of complex shape microparts

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Relatively to non-traditional and high-energy-beam micro-manufacturing technique, the micro-cutting technology has many merits. For instance, the machining range is bigger, the cost of equipments is much lower, and the productivity and machining accuracy are higher. Therefore, the micro-cutting technology will take an important effect on the machining technique of complex shape microparts. In this paper, based on selfly-developed machine tool, the precision cutting technology of complex shape microparts made of metal material was studied by analyzing the modeling method on complex shape, the means of toolpaths layout and the optimal selection for cutting parameters. On the basis of above work, a typical duralumin specimen of high precision, low surface roughness and complex shape micropart was manufactured. This result will provide favorable technical support for farther research on the micro-cutting technology.

    Full Text Available The book starts with an explanation of the reason why the terms found in the book are sometimes used in place of each other. The editors stated that when technological tools are used to establish an effective and productive study process in education, the concept of learning technology is used instead of educational technology. The editors of the book considers the field as complex and vague in terms of the fact that the meanings of the concepts are close to each other in the field of educational technology and that the field provides an opportunity for inter-disciplinary studies. However, according to the editors, this vagueness and complexity shows the superiority of the field. This superiority is explained with the fact that the field of educational technology requires upper-level skills of problem solving and critical thinking and that it presents a multi-dimensional and inter-disciplinary study field. The book was edited by Wanjira Kinuthia and Steward Marshall. Wanjira Kinuthia, an assistant professor at Georgia State University, works in the Department of Middle-Secondary Education and Instructional Technology. Steward Marshall, a professor at the University of the West Indies, is the director of the Distance Education Centre. The book includes five sections and 21 chapters. These sections are “Materials, Methods, and Modalities”, “Technology Implementation and Integration Issues”, “Student Engagement and Learning”, “Building Capacity”, “Using Technology for Performance Improvement and Productivity Enhancement”.

    Full Text Available BACKGROUND: The synthesis of published research in systematic reviews is essential when providing evidence to inform clinical and health policy decision-making. However, the validity of systematic reviews is threatened if journal publications represent a biased selection of all studies that have been conducted (dissemination bias. To investigate the extent of dissemination bias we conducted a systematic review that determined the proportion of studies published as peer-reviewed journal articles and investigated factors associated with full publication in cohorts of studies (i approved by research ethics committees (RECs or (ii included in trial registries. METHODS AND FINDINGS: Four bibliographic databases were searched for methodological research projects (MRPs without limitations for publication year, language or study location. The searches were supplemented by handsearching the references of included MRPs. We estimated the proportion of studies published using prediction intervals (PI and a random effects meta-analysis. Pooled odds ratios (OR were used to express associations between study characteristics and journal publication. Seventeen MRPs (23 publications evaluated cohorts of studies approved by RECs; the proportion of published studies had a PI between 22% and 72% and the weighted pooled proportion when combining estimates would be 46.2% (95% CI 40.2%-52.4%, I2 = 94.4%. Twenty-two MRPs (22 publications evaluated cohorts of studies included in trial registries; the PI of the proportion published ranged from 13% to 90% and the weighted pooled proportion would be 54.2% (95% CI 42.0%-65.9%, I2 = 98.9%. REC-approved studies with statistically significant results (compared with those without statistically significant results were more likely to be published (pooled OR 2.8; 95% CI 2.2-3.5. Phase-III trials were also more likely to be published than phase II trials (pooled OR 2.0; 95% CI 1.6-2.5. The probability of publication within two

    The prevalence of osteoarthritis is increasing globally but current compliance with rehabilitation remains poor. This study explores whether wearable sensors can be used to provide objective measures of performance with a view to using them as motivators to aid compliance to osteoarthritis rehabilitation. More specifically, the use of a novel attachable wearable sensor integrated into clothing and inertial measurement units located in two different positions, at the waist and thigh pocket, was investigated. Fourteen healthy volunteers were asked to complete exercises adapted from a knee osteoarthritis rehabilitation programme whilst wearing the three sensors including five times sit-to-stand test, treadmill walking at slow, preferred and fast speeds. The performances of the three sensors were validated against a motion capture system and an instrumented treadmill. The systems showed a high correlation (r(2) > 0.7) and agreement (mean difference range: -0.02-0.03 m, 0.005-0.68 s) with gold standards. The novel attachable wearable sensor was able to monitor exercise tasks as well as the inertial measurement units (ICC > 0.95). Results also suggested that a functional placement (e.g., situated in a pocket) is a valid position for performance monitoring. This study shows the potential use of wearable technologies for assessing subject performance during exercise and suggests functional solutions to enhance acceptance.

  19. Hurdling barriers through market uncertainty: Case studies ininnovative technology adoption

    Energy Technology Data Exchange (ETDEWEB)

    Payne, Christopher T.; Radspieler Jr., Anthony; Payne, Jack

    2002-08-18

    The crisis atmosphere surrounding electricity availability in California during the summer of 2001 produced two distinct phenomena in commercial energy consumption decision-making: desires to guarantee energy availability while blackouts were still widely anticipated, and desires to avoid or mitigate significant price increases when higher commercial electricity tariffs took effect. The climate of increased consideration of these factors seems to have led, in some cases, to greater willingness on the part of business decision-makers to consider highly innovative technologies. This paper examines three case studies of innovative technology adoption: retrofit of time-and-temperature signs on an office building; installation of fuel cells to supply power, heating, and cooling to the same building; and installation of a gas-fired heat pump at a microbrewery. We examine the decision process that led to adoption of these technologies. In each case, specific constraints had made more conventional energy-efficient technologies inapplicable. We examine how these barriers to technology adoption developed over time, how the California energy decision-making climate combined with the characteristics of these innovative technologies to overcome the barriers, and what the implications of hurdling these barriers are for future energy decisions within the firms.

    Full Text Available Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of age, participated in three focus group sessions. Major results indicated that young adults have very little knowledge on the use of Smartphone technology for weight loss but would like to use this type of technology to help them lose weight. Results also indicated that young adults struggle to make healthy food choices and have priorities that outweigh exercise and they need support and guidance to make better decisions. In conclusion, young adults would be open to using Smartphone technology for weight loss but also need feedback and guidance to help make healthy decisions.

    Full Text Available The objective of this study is to understand how small businesses can innovate through the generation of technological spin-offs, identifying motivations, influences and barriers to achieving this phenomenon. Through a qualitative and exploratory study, we analyzed four cases of technological spin-offs in Santa Catarina State. We collected data through field observations, historical data and semi-structured interviews. The main reasons found for spin-offs creation were: diversification and to complement the value chain of the parent company and to ensure greater focus for a specific technology. The main barrier was lack of capital. Government initiatives to support the creation of new businesses, coupled with the organizational culture open to entrepreneurship and investment in R&D, contributed to the development of spin-offs analyzed. This work contributes to the understanding that small and medium-sized technology-based companies are a source of technological spin-offs and can benefit from the occurrence of this process.

The aim of this paper is to analyse studying approach, the use of technologies and how they affect study habits in a population of university students addressed by the "Sportello Salute Giovani" ("Youth Health Information Desk" questionnaire. METHODS: 16 questions referred to the approach to studying and the use of technologies (number 77-93 were analyzed. Absolute and relative frequencies were calculated. Stratification for sex, age and socio-economic status were performed and Chi square test was used to test the difference between sex, age class and socio-economic groups. RESULTS: 99.7% of students declared to have at least one mobile phone and 68.7% to use smartphones, i-phones and i-pads. Males (20.9% vs 14.9% female, p < 0.05, older students (31.7% among 25-30 years old students vs 21.3% among 18-21 years old, p < 0.05 and students with the highest socio-economic level (87.8% vs 54.2% of the lowest seem more likely to use digital technologies/Internet for educational purposes. CONCLUSION: Our survey revealed that most college students still prefer approach the study using books instead of digital tools, but this attitude is conflicting with how many hours they use computers and surf Internet per weeks. Therefore, further studies are needed to understand better technology influence on study habits and its implication on health.

The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes). Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups.

    Identification and classification of microalgae are basis and premise in the study of physiological and biochemical characteristics for microalgae. Microalgae cells mainly consist of five kinds of biological molecules, including proteins, carbonhydrates, lipids, nucleic acids and pigments. These five kinds of biological molecules contents with different ratio in microalgae cells can be utilized to identify microalgae species as a supplement method. This paper investigated the application of Raman microspectroscopy technology in the field of rapid identification on different algae species such as aschlorella sp. and chlamydomonas sp. . Cultivated in the same conditions of culture medium, illumination duration and intensity, these two kinds of species of microalgae cells were immobilized by using agar, and then the samples were placed under 514. 5 nm Raman laser to collect Raman spectra of different growth periods of different species. An approach to remove fluorescence background in Raman spectra called Rolling Circle Filter (RCF) algorithm was adopted to remove the fluorescent background, and then some preprocessing methods were used to offset the baseline and smooth method of Savitzky-Golay was tried to make the spectra curves of total 80 samples smoother. Then 50 samples were randomly extracted from 80 samples for modeling, and the remaining 30 samples for independent validation. This paper adopted different pretreatment methods, and used the partial least squares (PLS) to establish model between the spectral data and the microalgae species, then compared the effects of different pretreatment methods. The results showed that with Raman microspectroscopy technology, the pretreatment method of max-peak ratio standardization was a more effective identification approach which utilizes the different content ratios of pigments of different microalgae species. This method could efficiently eliminate the influence on Raman signal due to different growth stages of

    2001-07-01

    Renewable Energy Technologies (RETS) have over the years become an integral part of the energy supply chain in most developed countries. Recent projections show that 13.5% of the world's primary energy supply comes from renewable and this figure has an aggregated annual growth rate of 16%. Wind has the highest annual growth rate of 22% while the least annual growth rate of 2% is for hydropower. The main push for renewable like wind in the OECD countries are environmental concerns and the business aspect in power generation. The situation is however completely different in Africa, where the thrust for RETs is developmental based. Although the continent has abundant renewable energy resources like solar, biomass, wind and hydro potential, they have remained largely unexploited. Several efforts have been made to help African countries like Zimbabwe to exploit such resources. The main objectives of this country study included review of Zimbabwe's development of past RETs, establish barriers related lessons learnt from such projects and currently running RETs projects, identify barriers experienced by other projects and then select a few barrier removal projects and then develop them with the help of all stake holders in the country. The methodology of this study involved a review of past RETs projects to establish barriers faced and barriers related lessons learnt. An examination of the policy instruments related to RETs was done to establish how they promote the dissemination of the technologies as well as their adequacy. A survey of all possible RETs projects in the country was carried out and in this survey the end-users were visited and interviewed by the research team. An initial workshop, which was attended by all stake holders, was held in November 1999. An Advisory committee on RETs in Zimbabwe was then set up comprising of various stake holders from government, the private sector, research institutions, interviewed end-users and the NGO community

    1993-09-01

    The Idaho National Engineering Laboratory (INEL) has initiated the design and development of a novel pulsed accelerator-based, active interrogation concept. The proposed concept, referred to as the Material Identification Technology (MIT), enables rapid (between accelerator pulses), non-destructive, elemental composition analysis of both nuclear and non-nuclear materials. Applications of this technique include material monitoring in support of counter-proliferation activities, such as export controls (at domestic and international inspection locations), SNM controls, nuclear weapon dismantlement, and chemical weapon verification. Material Identification Technology combines a pulsed, X-ray source (an electron accelerator) and a gamma detection system. The accelerator must maximize neutron production (pulse width, beam current, beam energy, and repetition rate) and minimize photon dose to the object. Current available accelerator technology can meet these requirements. The detection system must include detectors which provide adequate gamma energy resolution capability, rapid recovery after the initial X-ray interrogation pulse, and multiple single gamma event detection between accelerator pulses. Further research is required to develop the detection system. This report provides the initial feasibility assessment of the MIT concept.

    The paper describes a study on the effects of top management support, various techno-economic factors, organizational climate, and decision-making modes on the adoption of NASA innovations. Field research consisted of interviews and questionnaires directed to sixty-five organizations. Forty-five test cases where different decisions for adoption of ideas for new products or processes were made on NASA Tech Briefs were studied in relation to the effects of various factors on the degree of success of adoption, including: (1) the degree of general connection of the technology to the firm's existing operation, (2) the specificity of the relationship between the technology and some existing and recognized problem, (3) the degree of urgency of the problem to which the technology was related, (4) maturity of technology available to implement the technology, (5) availability of personnel and financial resources to implement the technology, (6) degree of top management interest, (7) the use of confrontation in joint-decision, (8) the use of smoothing in decision-making, and (9) the use of forcing in decision-making. It was found that top managements interest was important in the product cases only, and that the success of process innovations was dependent on the quality of information and the specificity of the relationship between the technology and some recognized existing problem.

    Full Text Available This article reports the results of a three-arm mixed methods pilot study of music therapy with premature infants and their caregivers in a Neonatal Intensive Care Unit (NICU in Bogotá, Colombia. The study included 19 medically stable babies born between the 30th and 37th week of gestation and their caregivers. Two intervention groups were compared with a control group. The objectives were to find out whether music therapy could help the neonates to stabilize their physiological states and help mothers to reduce anxiety and strengthen the relationship with their baby. The data collection included the babies´ weight gain, heart rate, oxygen saturation, size, cephalic perimeter and length of hospitalization. Mothers filled out the State-Trait Anxiety Inventory (STAI-C and the Mother-to-Infant Bonding Scale (MIBS before the first and after the last intervention. Thematic analysis was used to analyze the qualitative data obtained through questionnaires. A trend towards an increased weight gain for both intervention groups and a shorter length of hospitalization for one of the intervention groups was noticed. Anxiety and bonding in mothers appears not to follow linear trends, as new challenges arise for parents at different stages during hospitalization. Mothers stated that music therapy was helpful for them, their baby and their relationship with the baby. Mothers across the groups think that music therapy should be a regular offer in the NICU and that music therapy helps to humanize the NICU environment.

    The petroleum exploration activities have been performed by our own technology in the concession Block VI-I in Korean continental shelf for more than 10 years. Gas and gas condensate were discovered from several exploratory wells drilled in this block. This year, the news of another hit in the well of Gorae-V was very encouraging. Different from the previous gas discoveries, the reservoir properties and the productivity of Gorea-V well were excellent and the reserve estimate was very optimistic for the gas field development in this region. Gas consumption was very rapidly increased during recent years because of the image of cleaner fuel compared with other fossil fuels and convenience of usage. Korea is the fifth country in the world in terms of total quantity of petroleum consumption. This is the reason why the secure supply of oil and gas in the future is vital to our industry. The development of gas or gas condensate reservoir is different from that of oil reservoir. Especially sales contract must be made before the initiation of gas field exploitation. The production facilities including pipeline system must be selected and designed for further consideration. In this study, we have selected the 'K' offshore gas field where the water depth is 155 m and the distance from the shore is 50 km. The main purpose of this production system analysis is to select the optimum size and capacity of production facilities including pipeline in order to find the most appropriate production schedule. Production system analysis using nodal analysis includes deliverability calculation of the reservoir, production system optimization, recoverable reserve estimation, and performance forecast of the reservoir with three different production rate scenarios. The reservoir pressure is 4525 psia and the temperature is 248 deg.F. The OGIP of this reservoir was calculated as 24.64 BCF/well and the reservoir is expected to produce for up to 10 years. The porosity is 6% and the

    In this paper we present an introduction to the possibilities of NFC (Near Field Communication) technology in the University environment. NFC is the key for the development of interactive systems where "intelligent" objects interact with the user just only by touching the objects with a NFC device. We support that a University environment with active objects dispatching information and services to the users (students and teachers) can introduce an appropriate environment for the fulfillment of the new Educational European directives. Here, we briefly describe some of the possibilities of the NFC technology and we include an example of the use of NFC through a Smart Poster for a scenario where a Department directory is considered.

    Perioperative pain reduction, particularly during the first two days, is highly important for patients after total knee arthroplasty (TKA). Problems are not only caused by medical issues but by organization and hospital structure. The present study shows how the quality of pain management can be increased by implementing a standardized pain concept and simple, consistent benchmarking. All patients included into the study had undergone total knee arthroplasty. Outcome parameters were analyzed by means of a questionnaire on the first postoperative day. A multidisciplinary team implemented a regular procedure of data analyzes and external benchmarking by participating in a nationwide quality improvement project. At the beginning of the study, our hospital ranked 16th in terms of activity-related pain and 9th in patient satisfaction among 47 anonymized hospitals participating in the benchmarking project. At the end of the study, we had improved to 1st activity-related pain and to 2nd in patient satisfaction. Although benchmarking started and finished with the same standardized pain management concept, results were initially pure. Beside pharmacological treatment, interdisciplinary teamwork and benchmarking with direct feedback mechanisms are also very important for decreasing postoperative pain and for increasing patient satisfaction after TKA.

    Full Text Available This study aimed to make an economic evaluation of a high performance modern beekeeping technology leading to an increased bee family capacity. The new technology removes the disadvantages of the traditional one utilising just natural picking based on Robinia, Lime, sunflower and wild flora, most of times deeply affected by unfavourable climate conditions (drought, rainfalls and conducting to important bee losses during the winter season and mainly during the critical period till the next picking. The modern technology assures 75 % more bees per family, an increased queen laying capacity by 33 %,, a 50 % reduction of bee loss in winter season, by 20 % more honey , by 50 % more propolis, by 33 % more pollen, by 50 % more swarms, by 60 % more royal jelly and by 50 % more bee venom. The modern technology is based on a scientific feeding management applying a stimulating, completing and proteinic feeding (pollen cake and/or pollen substitutes such as: degreased powder milk 30 % and soya bean cake, involving peculiar costs ranking between USD 9.73-10.06 per family/year. The total bee rearing costs have been estimated at USD 17.83 in average per family/year, of which: 55.5 % feeding costs, 6.8 % queen replacement cost, 3.2 % treatments cost, 13.5 % costs for supplying new frames and combs,17.4 % transportation costs for moving of bee families and the remaining of 3.6 % labour costs. Taking into account a standard apiary (100 bee families of an increased power, a beekeeper can obtain an USD 12,100.4 annual income, by 55.9 % higher than in case of the traditional beekeeping technology. As a conclusion, the new technology assures a higher biological and economical efficiency, USD 3,350 profit gain that is a profit by 48 % higher than in case of the classic technology. For this reason, we recommend this modern technology to be implemented by beekeepers if they would like to transform their apiaries into high performance commercial farms.

    Reduced dietary sodium intake (sodium reduction) increases heart rate in some studies of animals and humans. As heart rate is independently associated with the development of heart failure and increased risk of premature death a potential increase in heart rate could be a harmful side-effect of sodium reduction. The purpose of the present meta-analysis was to investigate the effect of sodium reduction on heart rate. Relevant studies were retrieved from an updated pool of 176 randomized controlled trials (RCTs) published in the period 1973-2014. Sixty-three of the RCTs including 72 study populations reported data on heart rate. In a meta-analysis of these data sodium reduction increased heart rate with 1.65 beats per minute [95% CI: 1.19, 2.11], p sodium reduction increases heart rate by as much (2.4%) as it decreases blood pressure (2.5%). This side-effect, which may cause harmful health effects, contributes to the need for a revision of the present dietary guidelines.

    2009-06-01

    Accurate temperature measurement of shock-loaded systems continues to present experimental challenges. With short measurable time durations diagnostic methods are almost exclusively restricted to optical techniques. By preventing full sample pressure unloading, through the use of an anvil, partial release temperature measurements can be deduced from multiple wavelength optical pyrometry. This paper presents our recent studies of tin shocked to 28GPa including investigations exploring surface defects, anvil dimensions and the integration with emissivity diagnostics. The results indicate that a ring groove, 5mm across and with a nominal machined depth of 50 microns, acts to enhance the measured temperature by approximately 150K. Additionally on reducing the LiF anvil diameter from 20mm to 15mm, comparable partial release temperatures were observed. With the anticipated development of multiple anvil target designs, the smaller anvil diameter is desirable. British Crown Copyright 2009/MOD.

    A fuzzy framework based on an adaptive network fuzzy inference system (ANFIS) is proposed to evaluate the relative degradation of the basic subthreshold parameters due to hot-carrier effects for nanoscale thin-film double-gate (DG) MOSFETs.The effect of the channel length and thickness on the resulting degradation is addressed,and 2-D numerical simulations are used for the elaboration of the training database.Several membership function shapes are developed,and the best one in terms of accuracy is selected.The predicted results agree well with the 2-D numerical simulations and can be efficiently used to investigate the impact of the interface fixed charges and quantum confinement on nanoscale DG MOSFET subthreshold behavior.Therefore,the proposed ANFIS-based approach offers a simple and accurate technique to study nanoscale devices,including the hot-carrier and quantum effects.

Rather than evaluating these conceptions with reference to a single standard, the essay shows how different conceptions of politics serve distinct purposes: normative critique, two approaches to empirical description, and two views of democracy. I discuss each conception of politics with respect to how well it fulfills its apparent primary purpose, as well as its implications for the purpose of studying a key issue in contemporary democratic societies: the politicization of science. In this respect, the essay goes beyond classifying different conceptions of politics and also recommends the fifth conception as especially conducive to understanding and shaping the processes whereby science becomes a site or object of political activity. The essay also employs several analytical distinctions to help clarify the differences among conceptions of politics: between science as 'political' (adjective) and science as a site of 'politics' (noun), between spatial-conceptions and activity-conceptions of politics, between latent conflicts and actual conflicts, and between politics and power. The essay also makes the methodological argument that the politics of science and technology is best studied with concepts and methods that facilitate dialogue between actors and analysts. The main goal, however, is not to defend a particular view of politics, but to promote conversation on the conceptions of politics that animate research in social studies of science and technology.

    Full Text Available The technological environment in which Australian SMEs operate can be best described as dynamic and vital. The rate of technological change provides the SME owner/manger a complex and challenging operational context. Wireless applications are being developed that provide mobile devices with Internet content and E-business services. In Australia, the adoption of ecommerce by large organisations has been relatively high, however, the same cannot be said for SMEs, where adoption has been slower than other developed countries. In contrast, however, mobile telephone adoption and diffusion is relatively high by SMEs. Will SMEs who have been reluctant to adopt commerce technologies in the past be more ready to go on-line with the merging of the Internet and mobile data technologies? This exploratory study identifies attitudes, perceptions and issues for mobile data technologies by regional SME owner/managers across a range of industry sectors. The major issues include the sector the firm belongs to, the current adoption status of the firm, the level of mistrust of the IT industry, the cost of the technologies, and the applications and attributes of the technologies.

    Full Text Available Food technology innovation has the potential to deliver many benefits to society, although some technologies have been problematic in terms of public acceptance. In promoting the commercial success of innovative technological processes and resultant products it will be important to incorporate information relating to consumer preferences and concerns during their development. The barriers to the utilisation of consumer information during technological development was explored using a two round Delphi study involving 75 experts with an interest in new food technology (food technologists and consumer scientists. There was overall agreement that consumer information should be used in technology implementation and product design, and that good communication between key actors at pivotal stages during the development of new food technologies and products was important. However disciplinary differences were perceived to be a barrier to communication, as were difficulties associated with producing consumer information usable by food technologists. A strategy to improve inter-disciplinary communication is proposed, involving the creation of multi-disciplinary teams working together throughout the development project’s duration, including those with interdisciplinary experience. Deficiencies in the specification of the information required from consumer scientists need to be overcome. Consumer science results need to be concrete and presented as salient to and usable by food technologists.

    3D printing, as an additive process, offers much more than traditional machining techniques in terms of achievable complexity of a model shape. That fact was a motivation to adapt discussed technology as a method for creating objects purposed for aerodynamic testing. The following paper provides an overview of various 3D printing techniques. Four models of a standard NACA0018 aerofoil were manufactured in different materials and methods: MultiJet Modelling (MJM), Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM). Various parameters of the models have been included in the analysis: surface roughness, strength, details quality, surface imperfections and irregularities as well as thermal properties.

    Full Text Available Previous reports in this series have indicated the growing acceptance of video-conferencing in education delivery. The current report compares a series of video-conferencing methods in an activity requiring precision of expression and communication: theatre and performance studies. The Accessing and Networking with National and International Expertise (ANNIE project is a two-year project undertaken jointly by the University of Warwick and the University of Kent at Canterbury, running from March 2001 to March 2003. The project's aim is to enhance students' learning experience in theatre studies by enabling access to research-based teaching and to workshops led by practitioners of national and international standing. Various technologies have been used, particularly ISDN video-conferencing, computer-mediated conferencing, and the Internet. This report concludes that video-conferencing methods will gain acceptance in education, as academic schools themselves are able to operate commonly available technology the assistance of specialised service units.

    The objective of this study was to advance knowledge of the experience of multisite research staff with video conferencing mental health data collection among study participants with schizophrenia. An end-of-study focus group was conducted with all (N = 19) study coordinators of a multisite randomized trial of pharmacotherapy for schizophrenia to characterize the experiences of coordinators overseeing semistructured assessments via video conferencing technology (VCT). Researchers conducted an audiotaped voluntary focus group. Investigators independently coded a transcript of the focus group, followed by discussions to reach consensus on key themes. Three key themes emerged, involving issues associated with (a) the technology itself, (b) the technology in the context of clinical care and research, and (c) the feasibility of using VCT for study assessments, including coordinators' perceptions of participants' experience of VCT. Additional themes were that (a) interviewer skills appeared to moderate the impact of VCT, (b) research participants with serious psychiatric disorders who participated in VCT assessments appeared, overall, to be more amenable to the technology than research coordinators anticipated, and (c) because VCT will be adapted in a wide range of settings, staffing and resource needs should be considered in planning for and adopting VCT for psychiatric research or clinical assessment. This study adds contextual detail and emphasis to the existing literature on the use of VCT in research and factors regarding the effective deployment of the technology in research.

    In the present study, we have developed a code using Matlab software for solving a rectangular aluminum plate having void, notch, at different boundary conditions discretizing a two dimensional (2D) heat conduction equation by the finite difference technique. We have solved a 2D mixed boundary heat conduction problem analytically using Fourier integrals (Deb Nath et al., 2006; 2007; 2007; Deb Nath and Ahmed, 2008; Deb Nath, 2008; Deb Nath and Afsar, 2009; Deb Nath and Ahmed, 2009; 2009; Deb Nath et al., 2010; Deb Nath, 2013) and the same problem is also solved using the present code developed by the finite difference technique (Ahmed et al., 2005; Deb Nath, 2002; Deb Nath et al., 2008; Ahmed and Deb Nath, 2009; Deb Nath et al., 2011; Mohiuddin et al., 2012). To verify the soundness of the present heat conduction code results using the finite difference method, the distribution of temperature at some sections of a 2D heated plate obtained by the analytical method is compared with those of the plate obtained by the present finite difference method. Interpolation technique is used as an example when the boundary of the plate does not pass through the discretized grid points of the plate. Sometimes hot and cold fluids are passed through rectangular channels in industries and many types of technical equipment. The distribution of temperature of plates including notches, slots with different temperature boundary conditions are studied. Transient heat transfer in several pure metallic plates is also studied to find out the required time to reach equilibrium temperature. So, this study will help find design parameters of such structures.

    This paper presents time resolved laser induced luminescence (LIL) and diffuse reflectance laser flash-photolysis (DRLFP) studies of solid powdered samples of xanthione (XT) and 4H-1-benzopyran-4-thione (BPT). These thioketones form inclusion complexes with p-tert-butylcalix[6]arene (CLX[6]) and p-tert-butylcalix[8]arene (CLX[8]). Room temperature air equilibrated LIL studies for XT/CLX[8] inclusion complex have shown the existence of both fluorescence and delayed fluorescence emission (S 2 → S 0 emissions in the nanosecond and microsecond time ranges, respectively) peaking at ca. 460 nm while phosphorescence peaks at about 670 nm with a half life of about 4 μs. For the BPT/CLX[8] inclusion complex, the emissions now peak at ca. 450 and 630 nm, respectively. When these two thioketones are included into the CLX[6] nanocavities similar luminescence spectra were detected. The phosphorescence spectra in all cases present a clear vibrational structure characteristic of non-polar environments, in accordance with the non-polar character of the calixarene's cavities. Diffuse reflectance transient absorption spectra revealed in all cases the presence of the triplet state of the thioketones and also of longer lived species. The use of chromatographic methods (GC-MS) allowed us to identify the formation of xanthone, chromone and hydroxy-thioketones following laser irradiation at 355 or 337 nm.

  14. Laboratory Studies of the Reactive Chemistry and Changing CCN Properties of Secondary Organic Aerosol, Including Model Development

    The chemical evolution of secondary-organic-aerosol (SOA) particles and how this evolution alters their cloud-nucleating properties were studied. Simplified forms of full Koehler theory were targeted, specifically forms that contain only those aspects essential to describing the laboratory observations, because of the requirement to minimize computational burden for use in integrated climate and chemistry models. The associated data analysis and interpretation have therefore focused on model development in the framework of modified kappa-Koehler theory. Kappa is a single parameter describing effective hygroscopicity, grouping together several separate physicochemical parameters (e.g., molar volume, surface tension, and van't Hoff factor) that otherwise must be tracked and evaluated in an iterative full-Koehler equation in a large-scale model. A major finding of the project was that secondary organic materials produced by the oxidation of a range of biogenic volatile organic compounds for diverse conditions have kappa values bracketed in the range of 0.10 +/- 0.05. In these same experiments, somewhat incongruently there was significant chemical variation in the secondary organic material, especially oxidation state, as was indicated by changes in the particle mass spectra. Taken together, these findings then support the use of kappa as a simplified yet accurate general parameter to represent the CCN activation of secondary organic material in large-scale atmospheric and climate models, thereby greatly reducing the computational burden while simultaneously including the most recent mechanistic findings of laboratory studies.

    Genital herpes simplex virus-2 (HSV-2) shedding in pregnant women in association with neonatal herpes infection has been widely studied but there is limited evidence of its association with pregnancy outcomes. In this retrospective observational study, we included a subgroup of pregnant women who were enrolled in a randomized control behavioural intervention study that was conducted in South Africa in 2008-2010. In pregnancy, women had a HIV rapid test done and a genital swab taken to test for curable STIs and HSV-2 DNA. Subsequent visits were scheduled for 6, 10, 14 weeks and 9 months post-delivery. Pregnancy outcomes were documented at the 6-week or 10-week postpartum visit. Women were treated syndromically for curable STIs. Among 615 women included in this data analysis, 36.6% (n=225) tested HIV positive and 8.3% (n=51) tested positive for genital HSV-2 shedding during pregnancy. Women <24 years and HIV-1 seropositive women were 1.5 and 2.5 times more likely to test positive for HSV-2 genital shedding respectively. STI treatment records were available for 158/205 (77.1%) women; all 87 women with symptomatic STIs were treated the same day, and 50/71 (70.4%) asymptomatic women received treatment at the subsequent visit. Remaining 21 (29.6%) asymptomatic women did not receive treatment because they failed to return for antenatal follow-up. In a multivariable regression analysis, genital HSV-2 shedding, HIV-1, Neisseria gonorrhoea, Chlamydia trachomatis and Trichomanas vaginalis were not associated with preterm deliveries, still births and low birth weight. However with stratification by treatment for a STI, asymptomatic women who were not treated were 3.3 times more likely to deliver prematurely (33.3%; n=6/18) when compared to women who were treated during pregnancy (13.2%; n=15/114) (p=0.042). Genital HSV-2 shedding in pregnancy does not appear to alter pregnancy outcomes. Untreated curable STIs (T.vaginalis, C.trachomatis, N.gonorrhoea) were more likely

    Full Text Available Abstract Background Public concern about exposure to emissions from the regional industrial park (IP, including 17 chemical plants and the national industrial toxic waste site, initiated this study of the possible association between major congenital malformations (MCM and residence near the IP in Israel's Southern District. Methods The study was conducted during the period 1995–2000 and included 63,850 deliveries. Data on deliveries and MCM detected at births were obtained from the regional medical center, and stratified by ethnicity and type of locality. As exposure indicator we used distance categories (proximal and distant and predominant wind direction from the IP. Distance stratification was based on the geographical distribution of the localities and complaints about the odor related to IP emissions. Based on these complaints, localities up to 20 km from the IP were considered proximal to the IP. Results Average rates of MCM were 5.0% and 4.1% for Bedouin and Jewish newborns, respectively. The rate of MCM for Bedouin from proximal localities was significantly greater compared with distant localities (5.6% vs. 4.8%; RR = 1.17 with 95% CI: 1.04–1.29. In the proximal Bedouin permanent localities, the MCM rate reached 8.2 %, which was significantly higher than in distant areas (RR = 1.63, 95% CI: 1.39–1.80. Significant risk increase of central nervous system MCM was found in these localities, compared to distant ones (RR = 2.27, 95% CI: 1.44–3.60. Among newborns from the traditional tribal settlements, proximity to the IP was associated with increased rates of the following MCM: 1 all combined, 2 those associated with chromosomal abnormalities, and 3 those defined as "others unclassified MCM." Comparison of autosomal recessive disease rates by proximity to the IP in Bedouin newborns indicates that the observed increased risk of MCM is not explained by consanguineous marriages. The rates of MCM in the Jewish population were similar

    Increased consumer awareness and concern about microbial foodborne diseases has resulted in intensified efforts to reduce contamination of raw meat, as evidenced by new meat and poultry inspection regulations being implemented in the United States. In addition to requiring operation of meat and poultry slaughtering and processing plants under the principles of the hazard analysis critical control point (HACCP) system, the new regulations have established microbiological testing criteria for Escherichia coli and Salmonella, as a means of evaluating plant performance. These developments have renewed and intensified interest in the development and commercial application of meat and poultry decontamination procedures. Technologies developed and evaluated for decontamination include live animal cleaning/washing, chemical dehairing, carcass knife-trimming to remove physical contaminants, steam/hot water-vacuuming for spot-cleaning/decontamination of carcasses, spray washing/rinsing of carcasses with water of low or high pressures and temperatures or chemical solutions, and exposure of carcass sides to pressurized steam. Under appropriate conditions, the technologies applied to carcasses may reduce mean microbiological counts by approximately one-three log colony forming units (cfu)/cm2, and some of them have been approved and are employed in commercial applications (i.e., steam-vacuuming; carcass spray-washing with water, chlorine, organic acid or trisodium phosphate solutions; hot water deluging/spraying/rinsing, and pressurized steam). The contribution of these decontamination technologies to the enhancement of food safety will be determined over the long term, as surveillance data on microbial foodborne illness are collected. This review examines carcass decontamination technologies, other than organic acids, with emphasis placed on recent advances and commercial applications.

    The site selection for the future European Large Telescope (E-ELT) is a key issue within the European proposal funded by the European Union (EU), within the ``ELT design study'' proposal. The organization, working scheme and baseline frameworks are reviewed. For the definition of the working package WP12000 ``Site Characterization'', important use has been done of previous work in the definition of techniques and tools for the study of the atmosphere above observing sites. We have also taken advantage of the number of data already available which have naturally defined a ranking among the known places which have also been taken as a base line for pre-selecting the candidate sites. The work will last 4 years, it started in 2005 and is organized in subtasks, working packages WP, whose main objectives are the following: WP12100: to characterize two top astronomical sites (ORM and North-Paranal) and to explore three other alternatives (Macon in Argentina, Izaña in Spain and Aklim in Morocco) suitable to install an ELT under the best conditions (Dome C is been currently under investigation, and no particular effort will be put in this site, but rather its atmospheric properties will be compared to the above mentioned sites). WP12200 is dedicated to design, build and operate a set of standard equipment in all the sites and to perform long term campaign. WP12300 will investigate wavefront properties over large baselines (50-100 m) corresponding to the size of the future ELT, as well as the fine characterization of the optical turbulence within the boundary layer. A similar plan is being carried out by the Thirty Meter Telescope (TMT) site selection team. For the sake of saving resources (budget and people), the TMT preselected sites (all in the American Continent) are not included in our European study.

    The use of search filters (e. g. for study types) facilitates the process of literature searching. Regional limits might be helpful depending on the research question. Regional search filters are already available for some regions, but not for Germany. Our aim is to give an overview of applied search strategies in systematic reviews (SRs) focusing on Germany. We searched Medline (via Pubmed) applying a focused search strategy to identify SRs focusing on Germany in January 2016. Study selection and data extraction were performed by two reviewers independently. The search strategies with a focus on Germany were analyzed in terms of reasonableness and completeness relying on the Peer Review of Electronic Search Strategies (PRESS) criteria. A narrative evidence synthesis was performed. In total, 36 SRs (13 written in English) were included. 78% were published in 2012 or later. The majority (89%) of SRs utilized at least two different sources for their search with databases and checking references being the most common. 17 SRs did not use any truncations, ten SRs did not restrict their search to Germany, six SRs reported to have searched for German OR Germany. Only ten articles searched for the term Germany (occasionally jointly with the term Deutschland) without any use of an adjective such as German. There is a high interest in regionally focused SRs. The identified search strategies revealed a need for improvement. It would be helpful to develop a regional search filter for Germany that is able to identify studies performed in Germany.

    Research on stellarators has been carried out in Europe since the early years of the fusion programme. Early studies of this reactor concept were done at the Culham Laboratory of the UK Atomic Energy Authority. Such classical stellarators, however, have poor reactor prospects in spite of the significant advantage of not needing a large toroidal plasma current. It seemed to be just this large toroidal plasma current which has led to intrinsic deficiencies with respect to reactor potential of the tokamak. Expecting that these deficiencies would disappear for a concept without such a current, the Institut fuer Plasmaphysik developed, in a roll-back fashion, i.e. by starting from reactor considerations, the concept of the helical axis advanced stellarator (HELIAS). The results achieved look very promising indeed. Since tokamaks and stellarators show many similarities, there appeared no need as yet for a new stand-alone stellarator reactor study. The work was rather concentrated on the few but decisive differences between the two concepts and on evaluation of their relative importance. Studies on the coil system, the stress distribution in the supporting material, the space needed for an efficient blanket system, the properties of the exhaust system, etc. have been done. Applying contemporary scaling laws, it turns out that although the aspect ratio of such advanced stellarators is larger than that of tokamaks, the plasma volume is about the same. The magnetic energy needed for plasma confinement is considerably lower and the mass utilization tends to be larger than for comparable tokamaks. It also follows that a number of reactor components needed for tokamak operation (e.g. current drive, feedback stabilization, disruption prevention) are not needed in stellarators, making this type of reactor and its operation simpler. Such results would have a large influence on selection of the final concept and the further evolution of the fusion programme.

    Full Text Available Nowadays, spam has become serious issue for computer security, because it becomes a main source for disseminating threats, including viruses, worms and phishing attacks. Currently, a large volume of received emails are spam. Different approaches to combating these unwanted messages, including challenge response model, whitelisting, blacklisting, email signatures and different machine learning methods, are in place to deal with this issue. These solutions are available for end users but due to dynamic nature of Web, there is no 100% secure systems around the world which can handle this problem. In most of the cases spam detectors use machine learning techniques to filter web traffic. This work focuses on systematically analyzing the strength and weakness of current technologies for spam detection and taxonomy of known approaches is introduced.

    2012-04-01

    3D printing is one of the developments in rapid prototyping technology. The inception and development of the technology has highly assisted the product development phase of product design and manufacturing. The technology is particularly important in educating product design and 3D modeling because it helps students to visualize their design idea, to enhance their creative design process and enables them to touch and feel the result of their innovative work. The availability of many 3D printers on the market has created a certain level of challenge for the user. Among others, complexity of part geometry, material type, compatibility with 3D CAD models and other technical aspects still need in-depth study. This paper presents results of the experimental work on the capabilities and limitations of the Z510 3D printer from Z-corporation. Several parameters such as dimensional and geometrical accuracy, surface quality and strength as a function of model size, orientation and file exchange format are closely studied.

    The goal of the present study was to examine dietary adherence and acceptability among participants from the New DIETs study who were randomized to one of four plant-based diets (vegan, vegetarian, pesco-vegetarian, semi-vegetarian) or an omnivore diet. Primary outcomes at two- and six months included dietary adherence (24-hour dietary recalls), weight loss and changes in animal product intake (mg cholesterol) by adherence status, Three-Factor Eating Questionnaire (TFEQ), Power of Food Scale (PFS), dietary acceptability (Food Acceptability Questionnaire), and impact of diet preference on adherence. No differences were found in dietary adherence or changes in FAQ, TFEQ, or PFS among the groups. At six months, non-adherent vegan and vegetarian participants (n=16) had a significantly greater decrease in cholesterol intake (-190.2 ± 199.2 mg) than non-adherent pesco-vegetarian/semi-vegetarian (n=15, -2.3 ± 200.3 mg, P=0.02) or omnivore participants (n=7, 17.0 ± 36.0, P=0.04). Non-adherent vegan/vegetarian participants lost significantly more weight at six months (-6.0 ± 6.7%) than non-adherent omnivore participants (-0.4 ± 0.6%, P=0.04). Dietary preference had no impact on adherence at six months. Due to equal rates of adherence and acceptability among the diet groups, instructing participants to follow vegan or vegetarian diets may have a greater impact on weight loss and animal product intake than providing instruction in more moderate approaches even among non-adherent participants.

    Fragile X syndrome (FXS) is one of the most common causes of intellectual disability/developmental delay (ID/DD), especially in males. It is caused most often by CGG trinucleotide repeat expansions, and less frequently by point mutations and partial or full deletions of the FMR1 gene. The wide clinical spectrum of affected females partly depends on their X-inactivation status. Only few female ID/DD patients with microdeletions including FMR1 have been reported. We describe 3 female patients with 3.5-, 4.2- and 9.2-Mb de novo microdeletions in Xq27.3-q28 containing FMR1. X-inactivation was random in all patients, yet they presented with ID/DD as well as speech delay, macrocephaly and other features attributable to FXS. No signs of autism were present. Here, we further delineate the clinical spectrum of female patients with microdeletions. FMR1 expression studies gave no evidence for an absolute threshold below which signs of FXS present. Since FMR1 expression is known to be highly variable between unrelated females, and since FMR1 mRNA levels have been suggested to be more similar among family members, we further explored the possibility of an intrafamilial effect. Interestingly, FMR1 mRNA levels in all 3 patients were significantly lower than in their respective mothers, which was shown to be specific for patients with microdeletions containing FMR1.

    Knowledge management is paramount nowadays. In order to enable the members of an organization to deal with their current situations effectively it is mandatory to know and enhance its intellectual capital. Managing the organization knowledge is important to the extent that it allows and reinforce its mission (what we are trying to accomplish?), and performance (how do we deliver the results?). As a result of a knowledge management effort, the organization can create value for itself and for society as a whole. In this paper, we argue that a technology developed at a research institute and transferred to an industry is knowledge to be managed in order to create value, both for the society and for the Institute. In order to manage such knowledge, it is proposed an approach to enhance the value creation potential of a technology transfer. This paper propose an investigation to expand the understanding on how a public research institute and a private firm could introduce their value creation wishes into a technology transfer agreement in a way to reflect and provide the realization of those wishes. It is proposed that, from the identification of the organizations expectations it is possible to infer which agreement attributes will contribute to that value creation and to establish satisfactory agreement configurations. These configurations have the potential to generate those consequences, given that, through the transfer, each organization seeks to increase potential benefits and to reduce potential sacrifices. Supported by exchange flow and value creation models, by the knowledge management and the means-end theory, an approach to increase the value creation potential of a technology transfer is proposed. Evidences from a case study sustain the proposed approach. The case study unity is the Instituto de Engenharia Nuclear, a public research institute. (author)

    Neonicotinoid insecticides are nicotinic acetylcholine receptor agonists used worldwide. Their environmental health effects including neurotoxicity are of concern. We previously determined a metabolite of acetamiprid, N-desmethyl-acetamiprid in the urine of a patient, who exhibited some typical symptoms including neurological findings. We sought to investigate the association between urinary N-desmethyl-acetamiprid and the symptoms by a prevalence case-control study. Spot urine samples were collected from 35 symptomatic patients of unknown origin and 50 non-symptomatic volunteers (non-symptomatic group, NSG, 4-87 year-old). Patients with recent memory loss, finger tremor, and more than five of six symptoms (headache, general fatigue, palpitation/chest pain, abdominal pain, muscle pain/weakness/spasm, and cough) were in the typical symptomatic group (TSG, n = 19, 5-69 year-old); the rest were in the atypical symptomatic group (ASG, n = 16, 5-78 year-old). N-desmethyl-acetamiprid and six neonicotinoids in the urine were quantified by liquid chromatography-tandem mass spectrometry. The detection of N-desmethyl-acetamiprid was the most frequent and highest in TSG (47.4%, 6.0 ppb (frequency, maximum)), followed by in ASG (12.5%, 4.4 ppb) and in NSG (6.0%, 2.2 ppb), however acetamiprid was not detected. Thiamethoxam was detected in TSG (31.6%, 1.4 ppb), in ASG (6.3%, 1.9 ppb), but not in NSG. Nitenpyram was detected in TSG (10.5%, 1.2 ppb), in ASG (6.3%, not quantified) and in NSG (2.0%, not quantified). Clothianidin was only detected in ASG (6.3%, not quantified), and in NSG (2.0%, 1.6 ppb). Thiacloprid was detected in ASG (6.3%, 0.1 ppb). The cases in TSG with detection of N-desmethyl-acetamiprid and thiamethoxam were aged 5 to 62 years and 13 to 62 years, respectively. Detection of N-desmethyl-acetamiprid was associated with increased prevalence of the symptoms (odds ratio: 14, 95% confidence interval: 3.5-57). Urinary N-desmethyl-acetamiprid can be used as a

    From 1991 to 1996, key studies on the reutilization, treatment, and disposal technology of hazardous wastes have been incorporated into the national plan for environmental protection science and technology. At present, the research achievements have been accomplished, have passed national approval, and have been accepted. The author of this paper, as leader of the national group for this research work, expounds the newest achievements of the studies involving four parts: (1) the reutilization technology of electroplating sludge, including the ion-exchange process for recovering the sludge and waste liquor for producing chromium tanning agent and extracting chromium and colloidal protein from tanning waste residue; on the recovery of heavy metals from the electroplating waste liquor with microbic purification; on the demonstration project of producing modified plastics from the sludge and the waste plastics; and on the demonstration of the recovery of heavy metals from waste electroplating sludge by using the ammonia-leaching process; (2) the demonstrative research of reutilization technology of chromium waste residues, including production of self-melting ore and smelting of chromium-containing pig iron, and of pyrolytic detoxification of the residue with cyclone furnace; (3) the incineration technology of hazardous wastes with successful results of the industrial incinerator system for polychlorinated biphenyls; and (4) the safety landfill technology for disposal of hazardous wastes, with a complete set of technology for pretreatment, selection of the site, development of the antipercolating materials, and design and construction of the landfill. Only a part of the achievements is introduced in this paper, most of which has been built and is being operated for demonstration to further spreading application and accumulate experience. 6 refs., 7 figs., 6 tabs.

    Background: Cryopreservation is basically related to meritorious thin samples or small clumps of cells that are cooled quickly without loss. Our main objective is to establish and formulate an innovative method and protocol development for cryopreservation as a gold standard for clinical uses in laboratory practice and treatment. The knowledge regarding usefulness of cryopreservation in clinical practice is essential to carry forward the clinical practice and research. Materials and Methods: We are trying to compare different methods of cryopreservation (in two dozen of cells) at the same time we compare the embryo and oocyte freezing interms of fertilization rate according to the International standard protocol. Results: The combination of cryoprotectants and regimes of rapid cooling and rinsing during warming often allows successful cryopreservation of biological materials, particularly cell suspensions or thin tissue samples. Examples include semen, blood, tissue samples like tumors, histological cross-sections, human eggs and human embryos. Although presently many studies have reported that the children born from frozen embryos or “frosties,” show consistently positive results with no increase in birth defects or development abnormalities is quite good enough and similar to our study (50–85%). Conclusions: We ensure that cryopreservation technology provided useful cell survivability, tissue and organ preservation in a proper way. Although it varies according to different laboratory conditions, it is certainly beneficial for patient's treatment and research. Further studies are needed for standardization and development of new protocol. PMID:27512686

    A conceptual aircraft design study was recently completed which compared three supersonic multimission tactical aircraft. The aircraft were evaluated in two technology timeframes and were sized with consistent methods and technology assumptions so that the aircraft could be compared in operational utility or cost analysis trends. The three aircraft are a carrier-based Fighter/Attack aircraft, a land-based Multirole Fighter, and a Short Takeoff/Vertical Landing (STOVL) aircraft. This paper describes the design study ground rules used and the aircraft designed. The aircraft descriptions include weights, dimensions and layout, design mission and maneuver performance, and fallout mission performance. The effect of changing technology and mission requirements on the STOVL aircraft and the impact of aircraft navalization are discussed. Also discussed are the effects on the STOVL aircraft of both Thrust/Weight required in hover and design mission radius.

    Gender as a social construct is a recognized health determinant. Because best practice in reporting health technology assessment (HTA) clearly specifies the need to appraise a technology's social impact within the target population, the extent to which gender issues are taken into account in HTA production is of interest, not only in light of equitable practices but also for reasons of effectiveness. The aim of this study is to provide a first assessment of the degree of gender sensitivity shown by HTA agencies around the world today. The Web sites of sixty HTA agencies were analyzed. The consideration of gender aspects was specifically looked for in each agency's general mission statement, its priority setting process, and its methodological approach. Additionally, specific gender-oriented initiatives not belonging to any of the aforementioned categories were identified. Of the sixty agencies, less than half mention a commitment to addressing the social implication of health technologies. Only fifteen institutions make information on their priority setting principles available on their Web sites and gender was an issue in two of those cases. Data on methodology were obtainable online from 18 agencies, two of which mentioned gender issues explicitly. Finally, gender-oriented initiatives were identified by thirteen agencies. A gender-sensitive approach is apparently rarely adopted in current HTA production. Exceptional practices and relevant tools do exist and could serve as examples to be promoted by international collaborative networks.

    The anatomy of the accessory nerve has been well described but continued new clinical and anatomical findings exemplify our lack of a full understanding of the course of this nerve. Therefore, this study aimed to expand on our knowledge of the course of the 11th cranial nerve via anatomical dissections. Fifty-six cadavers (112 sides) underwent dissection of the accessory nerve from its cranial and spinal origins to its emergence into the posterior cervical triangle. Immunohistochemistry was performed when appropriate. Our findings included two cases (1.8%) where the nerve was duplicated, one intracranially and one extracranially. One accessory nerve (0.9%) was found to enter its own dural compartment within the jugular foramen. The majority of sides (80%) were found to have a cranial root of the accessory nerve. Thirty-one sides (28%) had connections to cervical dorsal roots medially and three sides (2.7%) laterally. Medial connections were most common with the C1 nerve. Medial components of these dorsal root connections were all sensory in nature. However, lateral components were motor on two sides (1.8%). Nerves traveled anterior to the internal jugular vein on 88% of sides. One (0.9%) left side nerve joined an interneural anastomosis between the dorsal rootlets. Macroganglia were found on the spinal part of the intracranial nerve on 13% of sides. The lesser occipital nerve arose directly from the accessory nerve on two sides (1.8%) and communicated with the accessory nerve on 5.4% of sides. One side (0.9%) was found to communicate with the facial nerve with both nerves innervating the sternocleidomastoid muscle. Additional anatomical knowledge of the variants of the accessory nerve may benefit patient care when this nerve is pathologically involved.

    Most studies assessing vegetation response following control of invasive Tamarix trees along southwestern U.S. rivers have been small in scale (e.g., river reach), or at a regional scale but with poor spatial-temporal replication, and most have not included testing the effects of a now widely used biological control. We monitored plant composition following Tamarix control along hydrologic, soil, and climatic gradients in 244 treated and 172 reference sites across six U.S. states. This represents the largest comprehensive assessment to date on the vegetation response to the four most common Tamarix control treatments. Biocontrol by a defoliating beetle (treatment 1) reduced the abundance of Tamarix less than active removal by mechanically using hand and chain-saws (2), heavy machinery (3) or burning (4). Tamarix abundance also decreased with lower temperatures, higher precipitation, and follow-up treatments for Tamarix resprouting. Native cover generally increased over time in active Tamarix removal sites, however, the increases observed were small and was not consistently increased by active revegetation. Overall, native cover was correlated to permanent stream flow, lower grazing pressure, lower soil salinity and temperatures, and higher precipitation. Species diversity also increased where Tamarix was removed. However, Tamarix treatments, especially those generating the highest disturbance (burning and heavy machinery), also often promoted secondary invasions of exotic forbs. The abundance of hydrophytic species was much lower in treated than in reference sites, suggesting that management of southwestern U.S. rivers has focused too much on weed control, overlooking restoration of fluvial processes that provide habitat for hydrophytic and floodplain vegetation. These results can help inform future management of Tamarix-infested rivers to restore hydrogeomorphic processes, increase native biodiversity and reduce abundance of noxious species.

    We report a GWAS of alcohol dependence (AD) in European-American (EA) and African-American (AA) populations, with replication in independent samples of EAs, AAs and Germans. Our sample for discovery and replication was 16 087 subjects, the largest sample for AD GWAS to date. Numerous genome-wide significant (GWS) associations were identified, many novel. Most associations were population specific, but in several cases were GWS in EAs and AAs for different SNPs at the same locus, showing biological convergence across populations. We confirmed well-known risk loci mapped to alcohol-metabolizing enzyme genes, notably ADH1B (EAs: Arg48His, P = 1.17 × 10−31; AAs: Arg369Cys, P = 6.33 × 10−17) and ADH1C in AAs (Thr151Thr, P = 4.94 × 10−10), and identified novel risk loci mapping to the ADH gene cluster on chromosome 4 and extending centromerically beyond it to include GWS associations at LOC100507053 in AAs (P = 2.63 × 10−11), PDLIM5 in EAs (P = 2.01 × 10−8), and METAP in AAs (P = 3.35 × 10−8). We also identified a novel GWS association (1.17 × 10−10) mapped to chromosome 2 at rs1437396, between MTIF2 and CCDC88A, across all of the EA and AA cohorts, with supportive gene expression evidence, and population-specific GWS for markers on chromosomes 5, 9 and 19. Several of the novel associations implicate direct involvement of, or interaction with, genes previously identified as schizophrenia risk loci. Confirmation of known AD risk loci supports the overall validity of the study; the novel loci are worthy of genetic and biological follow-up. The findings support a convergence of risk genes (but not necessarily risk alleles) between populations, and, to a lesser extent, between psychiatric traits. PMID:24166409

    To describe the baseline date and drugs therapy changes during treatment optimization in patients with heart failure with depressed systolic function included in the EFICAR study. Multicenter randomized clinical trial. Seven Health Centers. 150 patients (ICFSD) age 68±10 years, 77% male. Sociodemographic variables, comorbidities (Charlson index), functional capacity and quality of life. Drug therapy optimization was performed. The main etiology was ischemic heart disease (45%), with 89% in functional class II. The Charlson index was 2.03±1.05. The ejection fraction mean was 37%±8, 19% with ejection fraction <30%. With the stress test 6.3±1.6 mean was reached, with the 6 minutes test 446±78 meters and the chair test 13.7±4.4 seconds. The overall quality of life with ejection fraction was 22.8±18.7 and with the Short Form-36 Health Survey, physical health 43.3±8.4 and mental health 50.1±10.6. After optimizing the treatment, the percentage of patients on drugs therapy and the dose of angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists and beta-blockers were not changed. The majority of the subjects are in functional class II, with functional capacity and quality of life decreased and comorbidity index high. A protocolized drug therapy adjustment did not increase the dose or number of patients with effective drugs for heart failure with depressed systolic function.

    Full Text Available BACKGROUND: Psychological factors are known predictors of cardiovascular disease in many clinical settings, but data are lacking for HIV infection. We carried out a prospective cohort study to evaluate potential psychological predictors of preclinical and clinical vascular disease in HIV patients. METHODOLOGY/PRINCIPAL FINDINGS: HIV patients were consecutively enrolled. Demographics, viral and immune parameters and traditional cardiovascular predictors were considered; Intima-Media Thickness (c-IMT, continuous measure and Carotid Plaques (CPs, focal thickening ≥1.5 mm were investigated by B-mode ultrasonography; depressive symptoms by the Beck Depression Inventory (BDI-II, Type D personality (Distressed Personality or Type D by the DS14, alexithymia by the Toronto Alexithymia Scale (TAS-20. Vascular outcomes included transient ischemic attacks or stroke, acute coronary syndrome, myocardial or other organ infarction. We enrolled 232 HIV subjects, 73.9% males, aged 44.5±9.9 y, 38.2% with AIDS diagnosis, 18.3% untreated. Mean Nadir CD4 T-cell counts were 237.5±186.2/mmc. Of them, 224 (96.5% attended IMT measurements; 201 (86.6% attended both IMT assessment and psychological profiling. Mean follow-up was 782±308 days. Fifty-nine patients (29.4% had CPs at baseline. Nineteen patients (9.5% had ≥1 vascular event; 12 (6.0% died due to such events (n = 4 or any cause. At baseline cross-sectional multivariate analysis, increasing age, total cholesterol, current smoking and Alexithymia score≥50 were significantly associated with both increased cIMT (linear regression and CPs (logistic regression. At follow-up analysis, log-rank tests and Cox's regression revealed that only older age (p = 0.001, current smoking (p = 0.019 and alexithymia score≥50 (p = 0.013 were independently associated with vascular events. CONCLUSIONS/SIGNIFICANCE: In HIV-infected subjects, the Alexithymic trait emerges as a strong predictor of increased IMT, presence of CPs

    Lung functions are found to be impaired in coronary artery disease (CAD), congestive heart failure, left ventricular dysfunction, and after cardiac surgery. Diffusion capacity progressively worsens as the severity of CAD increases due to reduction in lung tissue participating in gas exchange. Pranayama breathing exercises and yogic postures may play an impressive role in improving cardio-respiratory efficiency and facilitating gas diffusion at the alveolo-capillary membrane. This study was done to see the effect of yoga regimen on lung functions particularly diffusion capacity in CAD patients. A total of 80 stable CAD patients below 65 years of age of both sexes were selected and randomized into two groups of 40 each. Group I CAD patients were given yoga regimen for 3 months which consisted of yogic postures, pranayama breathing exercises, dietary modification, and holistic teaching along with their conventional medicine while Group II CAD patients were put only on conventional medicine. Lung functions including diffusion capacity were recorded thrice in both the groups: 0 day as baseline, 22(nd) day and on 90(th) day by using computerized MS medisoft Cardio-respiratory Instrument, HYP'AIR Compact model of cardio-respiratory testing machine was manufactured by P K Morgan, India. The recorded parameters were statistically analyzed by repeated measures ANOVA followed by Tukey's test in both the groups. Cardiovascular parameters were also compared before and after intervention in both the groups. Statistically significant improvements were seen in slow vital capacity, forced vital capacity, peak expiratory flow rate, maximum voluntary ventilation, and diffusion factor/ transfer factor of lung for carbon monoxide after 3 months of yoga regimen in Group I. Forced expiratory volume in 1(st) sec (FEV1), and FEV1 % also showed a trend toward improvement although not statistically significant. HR, SBP and DBP also showed significant improvement in Group-I patients who

  18. Technology commercialization cost model and component case study

    Science.gov (United States)

    1991-12-01

    Fuel cells seem poised to emerge as a clean, efficient, and cost competitive source of fossil fuel based electric power and thermal energy. Sponsors of fuel cell technology development need to determine the validity and the attractiveness of a technology to the market in terms of meeting requirements and providing value which exceeds the total cost of ownership. Sponsors of fuel cell development have addressed this issue by requiring the developers to prepare projections of the future production cost of their fuel cells in commercial quantities. These projected costs, together with performance and life projections, provide a preliminary measure of the total value and cost of the product to the customer. Booz-Allen & Hamilton Inc. and Michael A. Cobb & Company have been retained in several assignments over the years to audit these cost projections. The audits have gone well beyond a simple review of the numbers. They have probed the underlying technical and financial assumptions, the sources of data on material and equipment costs, and explored issues such as the realistic manufacturing yields which can be expected in various processes. Based on the experience gained from these audits, DOE gave Booz-Allen and Michael A. Cobb & company the task to develop a criteria to be used in the execution of future fuel cell manufacturing cost studies. It was thought that such a criteria would make it easier to execute such studies in the future as well as to cause such studies to be more understandable and comparable.

    Executive Summary The Interagency Biological Restoration Demonstration—a program jointly funded by the Department of Defense's Defense Threat Reduction Agency and the Department of Homeland Security's (DHS's) Science and Technology Directorate—is developing policies, methods, plans, and applied technologies to restore large urban areas, critical infrastructures, and Department of Defense installations following the intentional release of a biological agent (anthrax) by terrorists. There is a perception that there should be a common system that can share information both vertically and horizontally amongst participating organizations as well as support analyses. A key question is: "How far away from this are we?" As part of this program, Pacific Northwest National Laboratory conducted research to identify the current information technology tools that would be used by organizations in the greater Seattle urban area in such a scenario, to define criteria for use in evaluating information technology tools, and to identify current gaps. Researchers interviewed 28 individuals representing 25 agencies in civilian and military organizations to identify the tools they currently use to capture data needed to support operations and decision making. The organizations can be grouped into five broad categories: defense (Department of Defense), environmental/ecological (Environmental Protection Agency/Ecology), public health and medical services, emergency management, and critical infrastructure. The types of information that would be communicated in a biological terrorism incident include critical infrastructure and resource status, safety and protection information, laboratory test results, and general emergency information. The most commonly used tools are WebEOC (web-enabled crisis information management systems with real-time information sharing), mass notification software, resource tracking software, and NW WARN (web-based information to protect critical

    The next-generation sequencing technologies are able to produce millions of short sequence reads in a high-throughput, cost-effective fashion. The emergence of these technologies has not only facilitated genome sequencing but also started to change the landscape of life sciences. Here, I survey their major applications ranging from whole-genome sequencing and resequencing, single nucleotide polymorphism (SNP) and structural variation discovery, to mRNA and noncoding RNA profiling and protein-nucleic acid interaction assay. These case studies in structural, functional and comparative genomics, metagenomics, and epigenomics are providing a more complete picture of the genome structures and functions. In the near future, we will witness broad impacts of these next-generation sequencing technologies for solving the complex biological problems in food, nutrition and agriculture. In this article, recent patents based information is also included.

    Full Text Available Growing importance of information technology (IT, as a strategic factor for organizations in achieving their objectives, have raised the concern of organizations in establishing and implementing effective IT governance. This study seeks to empirically examine the individual IT governance mechanisms that influence the overall effectiveness of IT governance. The data were obtained by using web based survey from 176 members of ISACA (Information Systems and Audit Control Association Australia. This study examines the influences of six proposed IT governance mechanisms on the overall effectiveness of IT governance. Using Factor Analysis and Multiple Regression techniques, the current study finds significant positive relationships between the overall level of effective IT governance and the following four IT governance mechanisms: the existence of ethics/ culture of compliance in IT, corporate communication systems, an IT strategy committee, and the involvement of senior management in IT.

    Full Text Available The following paper is concerned with elucidating an account of forms of new localism as they relate to the concept of ‘habitele’, a conceptual framework that helps us understand new forms of relatedness in the digitally mediated world. In doing this it will also reflect back on the concept and draw out as yet unconsidered elements based upon issues of fluidity, mobility, and what we will call ‘distal-locals’. The paper is centred around two case studies: the first is of a smart phone app, vouchercloud and details the way that the offering of money-off vouchers rests on particular notions of the local; while the second is of a environment organization who uses information technology to promote their activities. It is premised upon a history of work in the sociology of science and technology studies (STS and in particular a set of conceptual and methodologicalresources that helps to reveal the complexities of notions such as “the local”.

    We developed and pilot-tested an overall protocol for intervention studies to evaluate the effects of indoor environmental changes in office buildings on the health symptoms and comfort of occupants. The protocol includes a web-based survey to assess the occupant's responses, as well as specific features of study design and analysis. The pilot study, carried out on two similar floors in a single building, compared two types of ventilation system filter media. With support from the building's Facilities staff, the implementation of the filter change intervention went well. While the web-based survey tool worked well also, low overall response rates (21-34percent among the three work groups included) limited our ability to evaluate the filter intervention., The total number of questionnaires returned was low even though we extended the study from eight to ten weeks. Because another simultaneous study we conducted elsewhere using the same survey had a high response rate (>70percent), we conclude that the low response here resulted from issues specific to this pilot, including unexpected restrictions by some employing agencies on communication with occupants.

    1980-01-01

    Cogenerating electric power and process heat in single energy conversion systems rather than separately in utility plants and in process boilers is examined in terms of cost savings. The use of various advanced energy conversion systems are examined and compared with each other and with current technology systems for their savings in fuel energy, costs, and emissions in individual plants and on a national level. About fifty industrial processes from the target energy consuming sectors were used as a basis for matching a similar number of energy conversion systems that are considered as candidate which can be made available by the 1985 to 2000 time period. The sectors considered included food, textiles, lumber, paper, chemicals, petroleum, glass, and primary metals. The energy conversion systems included steam and gas turbines, diesels, thermionics, stirling, closed cycle and steam injected gas turbines, and fuel cells. Fuels considered were coal, both coal and petroleum based residual and distillate liquid fuels, and low Btu gas obtained through the on site gasification of coal. An attempt was made to use consistent assumptions and a consistent set of ground rules specified by NASA for determining performance and cost. Data and narrative descriptions of the industrial processes are given.

    carriage confirmed on stool culture. RESULTS Stool samples were obtained at study entry from 81% of participating residents. Over half of the samples contained antibiotic-resistant isolates, with Enterobacteriaceae resistant to ciprofloxacin in 47%. Residents were prescribed an average of 2.16 antibiotic prescriptions per year [95% confidence interval (CI) 1.90 to 2.46]. Antibiotics were less likely to be prescribed to residents from dual-registered homes. The incidence of AAD was 0.57 (95% CI 0.41 to 0.81) episodes per year among those residents who were prescribed antibiotics. AAD was more likely in residents who were prescribed co-amoxiclav than other antibiotics and in those residents who routinely used incontinence pads. AAD was less common in residents from residential homes. CONCLUSIONS Care home residents, particularly in nursing homes, are frequently prescribed antibiotics and often experience AAD. Antibiotic resistance, including ciprofloxacin resistance, is common in Enterobacteriaceae isolated from the stool of care home residents. Co-amoxiclav is associated with greater risk of AAD than other commonly prescribed antibiotics. TRIAL REGISTRATION Current Controlled Trials ISRCTN 7954844.

  19. Experimental study on MSW gasification and melting technology

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    In order to develop municipal solid waste (MSW) gasification and melting technology, two preliminary experiments and a principle integrated experiment were fulfilled respectively. The gasification characteristics of MSW are studied at 500-750℃ when equivalence ratio (ER) was 0.2-0.5 using a fluidized-bed gasifier. When temperature was 550-700℃ and ER was 0.2-0.4, low heat value (LHV) of syngas reaches 4000-12000 kJ/Nm3. The melting characteristics of fly ash were investigated at 1100-1460℃ using a fixed-bed furnace. It was proved that over 99.9% of dioxins could be decomposed and most heavy-metals could be solidified when temperature was 1100-1300℃. The principle integrated experiment was carried out in a fluidized-bed gasification and swirl-melting system. MSW was gasified efficiently at 550-650℃, swirl-melting furnace maintains at 1200-1300℃ stably and over 95% of fly ash could be caught by the swirl-melting furnace. The results provided much practical experience and basic data to develop MSW gasification and melting technology.

    Being an industrial dye, the Sudan I may have a toxic effect after oral intake on the body, and has recently been shown to cause cancer in rats, mice and rabbits. Because China and some other countries have detected the Sudan I in samples of the hot chilli powder and the chilli products, it is necessary to study the characteristics of this dye. As one kind of molecule scattering spectroscopy, Raman spectroscopy is characterized by the frequency excursion caused by interactions of molecules and photons. The frequency excursion reflects the margin between certain two vibrational or rotational energy states, and shows the information of the molecule. Because Raman spectroscopy can provides quick, easy, reproducible, and non-destructive analysis, both qualitative and quantitative, with no sample preparation required, Raman spectroscopy has been a particularly promising technique for analyzing the characteristics and structures of molecules, especially organic ones. Now, it has a broad application in biological, chemical, environmental and industrial applications. This paper firstly introduces Sudan I dye and the Raman spectroscopy technology, and then describes its application to the Sudan I. Secondly, the fingerprint spectra of the Sudan I are respectively assigned and analyzed in detail. Finally, the conclusion that the Raman spectroscopy technology is a powerful tool to determine the Sudan I is drawn.

    1994-01-01

    During the past 30 years as NASA has conducted technology transfer programs, it has gained considerable experience - particularly pertaining to the processes. However, three areas have not had much scrutiny: the examination of the contributions of the individuals who have developed successful spinoffs, the commercial success of the spinoffs themselves, and the degree to which they are understood by the public. In short, there has been limited evaluation to measure the success of technology transfer efforts mandated by Congress. Research conducted during the first year of a three-year NASA grant to the United States Space Foundation has taken the initial steps toward measuring the success of methodologies to accomplish that Congressionally-mandated technology transfer. In particular, the US Space Foundation, in cooperation with ARAC, technology transfer experts; JKA, a nationally recognized themed entertainment design company; and top evaluation consultants, inaugurated and evaluated a fresh approach including commercial practices to encourage, motivate, and energize technology transfer by: recognizing already successful efforts (Space Technology Hall of Fame Award), drawing potential business and industrial players into the process (Space Commerce Expo), and informing and motivating the general public (Space Technology Hall of Fame public venues). The first year's efforts are documented and directions for the future are outlined.

    2013-07-01

    We simulate the resonance Raman spectra of trans-stilbene using a recently developed time-independent method that allows computations of the full two-dimensional spectrum as a function of the incident and scattered frequencies, including both the Franck-Condon and the Herzberg-Teller contributions. The potential energy surfaces (PESs) of the ground and resonant states are described in the harmonic approximation using density functional theory PBE0/6-31+G(d,p) calculations in gas phase and in cyclohexane. The simulated spectra are in good agreement with the experimental data [J. Chem. Phys. 83, 5000 (1985)] measured at four different excitation wavelengths, and allow us to unambiguously assign the main experimental bands. We perform an extensive comparison of the performance of four different vertical or adiabatic models for the PES of the resonant state, dissecting the effects of nuclear displacements and Duschinsky mixings on the spectra.

    Objective To explore parents' views of extending the human papillomavirus (HPV) vaccination programme to also include boys. Design Explorative qualitative design using individual, face-to-face, interviews and inductive thematic analysis. Setting 11 strategically chosen municipalities in central Sweden. Participants Parents (n=42) who were offered HPV vaccination for their 11–12 years old daughter in the national school-based vaccination programme. Results The key themes were: equality from a public health perspective and perception of risk for disease. Parents expressed low knowledge and awareness about the health benefits of male HPV vaccination, and they perceived low risk for boys to get HPV. Some parents could not see any reason for vaccinating boys. However, many parents preferred gender-neutral vaccination, and some of the parents who had not accepted HPV vaccination for their daughter expressed that they would be willing to accept vaccination for their son, if it was offered. It was evident that there was both trust and distrust in authorities' decision to only vaccinate girls. Parents expressed a preference for increased sexual and reproductive health promotion such as more information about condom use. Some parents shared that it was more important to vaccinate girls than boys since they believed girls face a higher risk of deadly diseases associated with HPV, but some also believed girls might be more vulnerable to side effects of the vaccine. Conclusions A vaccine offered only to girls may cause parents to be hesitant to vaccinate, while also including boys in the national vaccination programme might improve parents' trust in the vaccine. More information about the health benefits of HPV vaccination for males is necessary to increase HPV vaccination among boys. This may eventually lead to increased HPV vaccine coverage among both girls and boys. PMID:28246143

    People with mild cognitive impairment and Alzheimer's disease are likely to be challenged by the multitude of everyday technology in today's society. The aim of this study was to explore how they try to prohibit, avoid or solve problems in everyday technology use, maintain skills, and learn to use new technology. To explore how the participants applied and reasoned about using everyday technology in real-life situations interviews were conducted while the participants used their own technology in their homes. Interviews were conducted with 20 participants with mild cognitive impairment (n = 10) or Alzheimer's disease (n = 10). The analyses were inspired from grounded theory and resulted in one core category and three sub-categories that represent sub-processes in the core. The core finding presents a continuous, intertwined process of learning and using everyday technology, highlighting how the context was interwoven in the processes. The participants used a rich variety of management strategies when approaching technology, including communication with the everyday technologies on different levels. The findings underscore that it is important to support continued use of everyday technology as long as it is valued and relevant to the person with mild cognitive impairment or Alzheimer's disease. The intertwined process of learning and using everyday technology suggests how support could target different sub-processes. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available The recent advances on information technology have made tremendous change on traditional banking. These days, people do not carry cash and prefer to use electronic devices such as point of sale system (POS or PIN entry devices (PinPad to do desirable transactions. These technologies could facilitate e-business and increase profitability in various industries including banking sector. The purpose of this paper is to investigate the effect of five new products namely ATM, POS Machines, PinPad machines, online and swift branches on banking performance indicators including return on assets (ROA, return on equities (ROE and operating investment return (OIR. We use the information of 19 private and governmental banks, which were active in Iran over the period of 2005-2010. The study uses linear regression analysis as well as VAR technique to study the effects of the independent variables on bank performance indicators. The results indicate that while there are some weak and positive relationships between three technology indicators including POS, PinPad and online businesses and ROA as well as ROE, there is relatively strong and positive relationship between these three independent variables and OIR. In addition, while the results of VAR analysis have shown that any reduction on PinPad will reduce OIR but this reduction will disappear after approximately four periods.

    The potential energy curves (PECs) of the 22 Λ-S states of the phosphorus monoiodide (PI) molecule have been calculated at the level of MRCI+Q method with correlation-consistent quadruple-ζ quality basis set. The spectroscopic constants of the bound states are determined, which well reproduce the available measurements. The metastable a1Δ state has been reported for the first time, which lies between the X3Σ- and b1Σ+ states and have much deeper well than the ground state. The R-dependent spin-orbit (SO) matrix elements are calculated with the full-electron Breit-Pauli operator. Based on the SO matrix elements, the perturbations that the 23Π state may suffer from are analyzed in detail. The SOC effect makes the original Λ-S states split into 51 Ω states. In the zero-field splitting of the ground state X3Σ-, the spin-spin coupling contribution (2.23 cm-1) is found to be much smaller compared to the spin-orbit coupling contribution (50 cm-1). The avoided crossings between the Ω states lead to much shallower potential wells and the change of dissociation relationships of the states. The Ω-state wavefunctions are analyzed depending on their Λ-S compositions, showing the strong interactions among several quasidegenerate Λ-S states of the same total SO symmetry. The transition properties including electric dipole (E1), magnetic dipole (M1), and electric quadrupole (E2) transition moments (TMs), the Franck-Condon factors, the transition probabilities and the radiative lifetimes are computed for the transitions between Ω components of a1Δ and b1Σ+ states and ground state. The transition probabilities induced by the E1, E2, and M1 transitions are evaluated. The E2 makes little effect on transition probabilities. In contrast, the E1 transition makes the main contribution to the transition probability and the M1 transition also brings the influence that cannot be neglected. Finally, the radiative lifetimes are determined with the transition moments including E

    Nowadays, mobile technologies are part of everyday life, but the lack of instruments to assess their acceptability for the management of chronic diseases makes their actual adoption for this purpose slow. The objective of this study was to develop a survey instrument for assessing patients' attitude toward and intention to use mobile technology for diabetes mellitus (DM) self-management, as well as to identify sociodemographic characteristics and quality of life factors that affect them. We first conducted the documentation and instrument design phases, which were subsequently followed by the pilot study and instrument validation. Afterward, the instrument was administered 103 patients (median age: 37 years; range: 18-65 years) diagnosed with type 1 or type 2 DM, who accepted to participate in the study. The reliability and construct validity were assessed by computing Cronbach's alpha and using factor analysis, respectively. The instrument included statements about the actual use of electronic devices for DM management, interaction between patient and physician, attitude toward using mobile technology, and quality of life evaluation. Cronbach's alpha was 0.9 for attitude toward using mobile technology and 0.97 for attitude toward using mobile device applications for DM self-management.

    Highlights: • In this case study, the seismic PSA methodology adopted for a CANDU 6 is presented. • Ambient vibrations testing to calibrate a 3D FEM and to reduce uncertainties is performed. • Procedure for the development of FRS for the RB considering wave incoherency effect is proposed. • Seismic fragility analysis for the RB is presented. - Abstract: Following the 2011 Fukushima Daiichi nuclear accident in Japan there is a worldwide interest in reducing uncertainties in seismic safety assessment of existing nuclear power plant (NPP). Within the scope of a Canadian refurbishment project of a CANDU 6 (NPP) put in service in 1983, structures and equipment must sustain a new seismic demand characterised by the uniform hazard spectrum (UHS) obtained from a site specific study defined for a return period of 1/10,000 years. This UHS exhibits larger spectral ordinates in the high-frequency range than those used in design. To reduce modeling uncertainties as part of a seismic probabilistic safety assessment (PSA), Hydro-Québec developed a procedure using ambient vibrations testing to calibrate a detailed 3D finite element model (FEM) of the containment and reactor building (RB). This calibrated FE model is then used for generating floor response spectra (FRS) based on ground motion time histories compatible with the UHS. Seismic fragility analyses of the reactor building (RB) and structural components are also performed in the context of a case study. Because the RB is founded on a large circular raft, it is possible to consider the effect of the seismic wave incoherency to filter out the high-frequency content, mainly above 10 Hz, using the incoherency transfer function (ITF) method. This allows reducing significantly the non-necessary conservatism in resulting FRS, an important issue for an existing NPP. The proposed case study, and related methodology using ambient vibration testing, is particularly useful to engineers involved in seismic re-evaluation of

    We investigated the association of psychosocial problems, menopausal symptoms such as hot flushes, and trends of smoking and use of cosmetics in our previous study. In this follow-up study, we researched psychiatric disorders and psychosocial problems in menopausal women. We designed a cohort study with 577 Japanese women aged 30-64 years. Subjects were selected randomly from among women who visited the department of gender-specific medicine at Tokyo Women's Medical University East Medical Center between June 2010 and September 2011. We analysed trends such as smoking, using cosmetics, and menopausal symptoms and their association with the first lifetime episode of severe depression and anxiety using structured clinical interviews for the DSM-IV (structured clinical interview for DSM-IV, outpatient version [SCID]), the Center for Epidemiological Studies Depression Scale (CES-D) and the State-Trait Anxiety Inventory (STAI). Significant associations were observed between hot flushes, smoking and the frequency of using cosmetics. Furthermore, the trends in cosmetic use and smoking affected not only psychosocial problems, but also physical problems. Younger women suffered from psychosocial problems more than twice the rate of post-menopausal women. Those who reported their first severe depression episode were also affected by severe anxiety disorders and physical problems. By self-checking the frequency of using cosmetics is up to date knowledge of psychosocial mood problems and improving women's quality of life. © 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    Full Text Available Article presents the preliminary results of mineralogical and geochemical studies of the primary and epigenetic properties of the bio-mineral and protein components in the fossil bone detritus as an example of first step of continued interdisciplinary research program. During the further implementation of this program, it is expected not only to solve a set of interrelated mineralogical, paleontological, paleoecological, paleoclimatic, and archaeological problems, but also to obtain new knowledge about the coevolution of organic, organo-mineral and inorganic substances in the geological history. The main objects of study are the fossil remains of the large Pleistocene mammals (mammoths, woolly rhinoceroses, deer, elk, horses, bison, cave and brown bear found on the territory of the Pechora Urals (62-67 ° N , South Pri-Irtyshie in Western Siberia (57-58 ° N, and Northern Taymyr (75-77 ° N. The oldest bone of Homo sapiens (Ust-Ishim human found in Northern Eurasia and remains of medieval Tobol and Irtysh Turk will be investigated as well. The results of previous studies of skin and hair of biological material from today's wild fisheries (analogues Pleistocene mammals, wild and domestic animals are considered as the reliable prerequisites for planned isotopic and geochemical studies. Use of cutting-edge research techniques will allow determining the chemical composition of bones; the elemental composition of bone collagen and bone proteins; the degree of crystallinity of bone bioapatite, and phase composition of xenomineral impurities; the isotopic composition of carbon, oxygen, and nitrogen in bioapatite and collagen; the actual molecular and crystal structure of the protein biomineral, and bone substance; the concentration of trace elements; the conditions and duration of burial and reburial of bone detritus; bone collagen bacterial degradation at an early stage of fossilization. It is expected that the implementation of the proposed project

    Verrucous carcinoma (VC) is a rare and distinct clinicopathologic variant of well-differentiated squamous cell carcinoma (SCC). This study aims to evaluate the histomorphology, proliferative activity, level of angiogenesis, and DNA ploidy of these pathological entities. This was a retrospective-prospective study of 18 cases of verrucous hyperplasia (VH), 41 cases of VC, and 44 cases of SCC. Immunohistochemical analysis for Ki-67 (MIB-1) and CD34 were performed. The tumor proliferative index, endothelial proliferative index and microvascular density were calculated. DNA ploidy was determined using image cytometry. The age range and gender ratio were similar in all three groups. The differences in MIB-1 labeling index (p = 0.0001), microvascular density (p = 0.01), and endothelial proliferative index (p = 0.001) between VC and SCC were found to be statistically significant. A non-significant increasing trend was observed in all of these parameters between VH and VC. On ploidy analysis, 100 % of SCC cases were aneuploid, compared to 39 % of VH and 86 % of VC cases. Our study demonstrates a significant difference in tumor proliferation, microvessel density, and ploidy between VC and SCC while increasing trend between VH and VC. These parameters, along with morphological findings, may be useful in differentiating these entities in small mucosal biopsies.

    Industrialized and welfare societies are faced with vast challenges in the field of healthcare in the years to come. New technological opportunities and implementation of welfare technology through co-creation are considered part of the solution to this challenge. Resistance to new technology and resistance to change is, however, assumed to rise from employees, care receivers and next of kin. The purpose of this article is to identify and describe forms of resistance that emerged in five municipalities during a technology implementation project as part of the care for older people. This is a longitudinal, single-embedded case study with elements of action research, following an implementation of welfare technology in the municipal healthcare services. Participants included staff from the municipalities, a network of technology developers and a group of researchers. Data from interviews, focus groups and participatory observation were analysed. Resistance to co-creation and implementation was found in all groups of stakeholders, mirroring the complexity of the municipal context. Four main forms of resistance were identified: 1) organizational resistance, 2) cultural resistance, 3) technological resistance and 4) ethical resistance, each including several subforms. The resistance emerges from a variety of perceived threats, partly parallel to, partly across the four main forms of resistance, such as a) threats to stability and predictability (fear of change), b) threats to role and group identity (fear of losing power or control) and c) threats to basic healthcare values (fear of losing moral or professional integrity). The study refines the categorization of resistance to the implementation of welfare technology in healthcare settings. It identifies resistance categories, how resistance changes over time and suggests that resistance may play a productive role when the implementation is organized as a co-creation process. This indicates that the importance of

    Exercise-induced oxygen desaturation (EID) is related to mortality in patients with chronic obstructive pulmonary disease (COPD). We investigated: (1) the prevalence of EID; (2) the relative-weight of several physiological determinants of EID including pulmonary emphysema, and (3) the relationship of EID with certain patients' clinical characteristics. Data from 2050 COPD patients (age: 63.3 ± 7.1years; FEV1: 48.7 ± 15.7%pred.) were analyzed. The occurrence of EID (SpO2post ≤88%) at the six-minute walking test (6MWT) was investigated in association with emphysema quantified by computed-tomography (QCT), and several clinical characteristics. 435 patients (21%) exhibited EID. Subjects with EID had more QCT-emphysema, lower exercise capacity and worse health-status (BODE, ADO indexes) compared to non-EID. Determinant of EID were obesity (BMI≥30 kg/m(2)), impaired FEV1 (≤44%pred.), moderate or worse emphysema, and low SpO2 at rest (≤93%). Linear regression indicated that each 1-point increase on the ADO-score independently elevates odds ratio (≤1.5fold) for EID. About one in five COPD patients in the ECLIPSE cohort present EID. Advanced emphysema is associated with EID. In addition, obesity, severe airflow limitation, and low resting oxygen saturation increase the risk for EID. Patients with EID in GOLD stage II have higher odds to have moderate or worse emphysema compared those with EID in GOLD stage III-IV. Emphysematous patients with high ADO-score should be monitored for EID.

  13. Parametric Meta-Technology Frameworks to Study Technical Efficiency and Macro-Economic Effects in the European Banking System

    Full Text Available Bank efficiency scores usually serve as a tool for comparing institutions with each other while allowing us to quantify sub-optimal decision-making unit choices. In the case of inter-country comparisons, such differences can also arise because of macro-economic heterogeneity between countries. Previous studies estimated a common technology limit for a sample of banking institutions in different countries. The contribution of our paper is that we employ a parametric approach to specify meta-frontiers and to study the effect of macro-economic heterogeneity on banking technology development. First, we use a parametric directional distance function to specify the appropriate technology frontier for each nation and the meta-technology frontier that includes all country-specific frontiers. Then, we define the directional technology gap ratio referring to the inefficiency scores evaluated from meta-technology and country-specific technology frontiers. The estimated parameters are more significant in our model than in the general model, also called the common frontier model. Comparing the results of our model to those of common frontiers, we find a substantial variation not only in inefficiency scores but also in countries’ rankings. While resorting to a pooled linear regression model, we demonstrate that the assessed technology gap ratio exhibits a significant association with inflation rates and per capita GDP. This result proves the influence of macro-economic heterogeneity on banks’ efficiency and technological development.

    This project involved the synthesis of microporous graphitic-carbon powders with subnanometer average pore size, and very narrow pore size distributions, and the use of these materials in experimental studies of pore-fluid structure and dynamics. Samples of carbide-derived carbon powder, synthesized by extraction of the metal cations from TiC by a high temperature chlorination process, followed by high temperature vacuum annealing, were prepared by Ranjan Dash and his associates at CRADA partner Y-Carbon, Inc. The resulting material had average pore sizes ranging from 5 to 8 . These powders were used in two experiments conducted by researchers involved in the Energy Frontier Research Center Directed by David J. Wesolowski at ORNL, the Fluid Interface Reactions, Structures and Transport (FIRST) Center. FIRST-funded researchers at Drexel University collaborated with scientists at the Paul Scherrer Institute, Switzerland, to measure the expansion and contraction of the microporous carbon particles during charging and discharging of supercapactor electrodes composed of these particles (Hantell et al., 2011, Electrochemistry Communications, v. 13, pp. 1221-1224.) in an electrolyte composed of tetraethylammonium tetrafluoroborate dissolved in acetonitrile. In the second experiment, researchers at Oak Ridge National Laboratory and Drexel University conducted quasielastic neutron scattering studies of the diffusional dynamics of water imbibed into the micropores of the same material (Chathoth et al., 2011, EuroPhysics Journal, v. 95, pp. 56001/1-6). These studies helped to establish the role of pores approaching the size of the solvent and dissolved ions in altering diffusional dynamics, ion transport and physical response of conducting substrates to ion desolvation and entry into subnamometer pores.

    Full Text Available Anja Vogt1, Ursula Kassner1, Ulrike Hostalek2, Elisabeth Steinhagen-Thiessen11Charite-Universitatsmedizin Berlin, Germany; 2Merck KGaA, Darmstadt, GermanyAbstract: Low HDL-cholesterol (<1.02 mmol/L [40 mg/dL] in men or <1.29 mmol/L [50 mg/dL] in women occurs in about one-third of European patients with dyslipidemia and is an independent cardiovascular risk factor. Simultaneous correction of low HDL-cholesterol and high totalcholesterol and LDL-cholesterol may provide reductions in cardiovascular morbidity and mortality beyond those possible with statins alone. Nicotinic acid (niacin in the US is the most effective means of increasing HDL-cholesterol available and has been shown to reduce cardiovascular event rates significantly. Niaspan® (prolonged-release nicotinic acid provides a convenient, once-daily means of administering nicotinic acid. Clinical studies with Niaspan® have demonstrated marked, long-term increases in HDL-cholesterol with additional useful benefits on triglycerides, LDLcholesterol, and lipid sub-profiles. The NAUTILUS study demonstrated the beneficial efficacy and tolerability profiles of Niaspan® in a usual-care setting. The most common side-effect of Niaspan® is flushing, which infrequently causes treatment discontinuation and which usually subsides over continued treatment. The ARBITER 2 and ARBITER 3 studies showed 1–2 years of treatment with Niaspan® plus a statin induced regression of atherosclerosis in patients with coronary artery disease. The effect of Niaspan®-statin treatment, relative to a statin alone, on clinical cardiovascular outcomes is currently under evaluation. Niaspan® represents a practical means of correcting low HDL-cholesterol, an independent risk factor for adverse cardiovascular outcomes.Keywords: prolonged-release nicotinic acid, Niaspan®, niacin, dyslipidemia, HDL-cholesterol cardiovascular risk

    The potential of high-power lasers for detailed studies of strongly coupled plasmas at low entropy is discussed, emphasizing multiple-shock techniques. Some outstanding features like metallization in solids and related ionization phase transitions in the fluid phase{emdash}predicted theoretically, but not yet observed experimentally{emdash}are reviewed. Planar multiple shock compression of solid hydrogen is described, using reverberating shocks between massive liners and, alternatively, a stepped pressure pulse acting from one side. In the latter case, shock splitting and a rarefaction shock show up at the metallic phase transition. {copyright} {ital 1996 American Institute of Physics.}

    Refractive errors are common eye disorders of public health importance worldwide. Ocular axial length (AL) is the major determinant of refraction and thus of myopia and hyperopia. We conducted a meta-analysis of genome-wide association studies for AL, combining 12,531 Europeans and 8,216 Asians. We identified eight genome-wide significant loci for AL (RSPO1, C3orf26, LAMA2, GJD2, ZNRF3, CD55, MIP, and ALPPL2) and confirmed one previously reported AL locus (ZC3H11B). Of the nine loci, five (LA...

    Refractive errors are common eye disorders of public health importance worldwide. Ocular axial length (AL) is the major determinant of refraction and thus of myopia and hyperopia. We conducted a meta-analysis of genome-wide association studies for AL, combining 12,531 Europeans and 8,216 Asians. We identified eight genome-wide significant loci for AL (RSPO1, C3orf26, LAMA2, GJD2, ZNRF3, CD55, MIP, and ALPPL2) and confirmed one previously reported AL locus (ZC3H11B). Of the nine loci, five (LAMA2, GJD2, CD55, ALPPL2, and ZC3H11B) were associated with refraction in 18 independent cohorts (n = 23,591). Differential gene expression was observed for these loci in minus-lens-induced myopia mouse experiments and human ocular tissues. Two of the AL genes, RSPO1 and ZNRF3, are involved in Wnt signaling, a pathway playing a major role in the regulation of eyeball size. This study provides evidence of shared genes between AL and refraction, but importantly also suggests that these traits may have unique pathways. PMID:24144296

    We conducted a phase 2 study of ruxolitinib in patients with relapsed/refractory leukemias. Patients with acceptable performance status (0-2), adequate organ function, and no active infection, received ruxolitinib 25 mg orally twice a day for 4 weeks (1 cycle). Response was assessed after every 2 cycles of treatment, and patients who completed 2 cycles were allowed to continue treatment until disease progression. Dose escalation to 50 mg twice daily was permitted in patients demonstrating a benefit. Thirty-eight patients, with a median age of 69 years (range, 45-88), were treated. The median number of prior therapies was 2 (range, 1-6). Twelve patients had JAK2V617F mutation. Patients received a median of 2 cycles of therapy (range, 1-22). Three of 18 patients with postmyeloproliferative neoplasm (MPN) acute myeloid leukemia (AML) showed a significant response; 2 achieved complete remission (CR) and one achieved a CR with insufficient recovery of blood counts (CRi). The responding patients with palpable spleens also had significant reductions in spleen size. Overall, ruxolitinib was very well tolerated with only 4 patients having grade 3 or higher toxicity. Ruxolitinib has modest antileukemic activity as a single agent, particularly in patients with post-MPN AML. The study was registered at www.clinicaltrials.gov as NCT00674479. PMID:22422826

    The need-to-belong theory stipulates that social exclusion (i.e., being rejected by peers) impairs the ability to self-regulate, and experimental studies with adults support this contention, at least on a short-term basis. Few studies have investigated whether social exclusion affects the development of self-regulation of children in a more enduring manner. By using data from a community sample of 762 children, we investigated reciprocal relations between social exclusion and self-regulation from age 4 to age 6. Social exclusion was reported by teachers, whereas self-regulation was reported by parents. Autoregressive latent cross-lagged analyses showed that social exclusion predicted impaired development of dispositional self-regulation and, reciprocally, that poor self-regulation predicted enhanced social exclusion. In other words, social exclusion undermines children's development of self-regulation, whereas poor self-regulation increases the likelihood of exclusion. Results illuminate the applied relevance of the need-to-belong theory.

    To assess the influence of the (106) Rh gamma spectrum on the Monte Carlo simulation of (106) Ru/(106) Rh ophthalmic plaques, which has been neglected without a quantitative estimation in all previous publications. Simulations were run with the penelope 2014 Monte Carlo code for radiation transport. Depth-dose distributions in water were simulated for the plaque models CCA, CCC, CCX and CIA. In addition to the (106) Rh beta spectrum, all gamma components from the (106) Rh gamma spectrum were included in the simulations. Depth-dose curves were compared with those obtained without considering the (106) Rh gamma spectrum. Moreover, half-value (HVL) and tenth-value layers (TVL) were estimated for the (106) Rh gamma spectrum in water, PMMA, stainless steel and lead. Some practical radiation protection applications were discussed. Parallel computing was implemented to reduce computing time. The contribution of the (106) Rh gamma spectrum on the depth-dose curves is negligible at depths of clinical interest. The HVL and TVL of the (106) Rh gamma spectrum were found to be similar to those of (137) Cs. The air-kerma rate at 1 m for a CCA plaque in typical clinical conditions was about 0.4μGym2h-1, resulting in equivalent doses at that point elow 0.05 mSv during a treatment. The air-kerma rate would be underestimated by a factor of 5 if the (106) Rh gamma spectrum were not considered. Also, a freely available software tool was developed to ease parallelization of penelope 2014 simulations that use penmain as steering main program. The influence of the (106) Rh gamma spectrum is not relevant for clinical purposes, thus validating the common assumption from the literature. However, for simulations at large distances from the plaques, such as for radiation shielding assessment and estimation of dose to personnel, the gamma spectrum from (106) Rh must be taken into account to obtain accurate results. © 2017 American Association of Physicists in Medicine.

    The projects for the joint development of technology common to the civilian and military sectors are being carried out at national level to maximize the utilization of limited resources. The technologies have been identified through a process which considered whether they are duplicates of the present military technology, whether they are necessary, and whether their realization is feasible. In addition, the problems surfaced during the identification process have been analyzed and suggestions to vitalize the military application of civilian nuclear technology are presented in the contexts of personal channel, institutional networking, R and D information exchange, and budgetary support.

  7. Health information management using optical storage technology: case studies.

    Science.gov (United States)

    Kohn, D

    1992-05-01

    All the health care facilities examined in the case studies addressed several important organizational issues before and during the installation of their systems. All the facilities examined employee commitment. The prudent managers considered how easily their employees adapt to changes in their jobs and work environment. They considered how enthusiastic cooperation can be fostered in the creation of a liberated and reengineered office. This was determined not only by each individual's reaction to change, but also by the health care facility's track record with other system installations. For example, document image, diagnostic image, and coded data processing systems allow the integration of divergent health care information systems within complex institutions. Unfortunately, many institutions are currently struggling with how to create an information management architecture that will integrate their mature systems, such as their patient care and financial systems. Information managers must realize that if optical storage technology-based systems are used in a strategic and planned fashion, these systems can act as focal points for systems integration, not as promises to further confuse the issue. Another issue that needed attention in all the examples was the work environment. The managers considered how the work environment was going to affect the ability to integrate optical image and data systems into the institution. For example, many of these medical centers have created alliances with clinics, HMOs, and large corporate users of medical services. This created a demand for all or part of the health information outside the confines of the original institution. Since the work environment is composed of a handful of factors such as merged medical services, as many work environment factors as possible were addressed before application of the optical storage technology solution in the institutions. And finally, the third critical issue was the organization of work

    Full Text Available Myostracum, which is connected from the umbo to the edge of a scar, is not a single layer composed of prismatic layers, but a hierarchically complex multilayered shape composed of minerals and an organic matrix. Through the analysis of the secondary structure, the results revealed that a β-antiparallel structure was predominant in the mineral phase interface between the myostracum (aragonite and bottom folia (calcite. After the complete decalcification and deproteinization, the membrane obtained from the interface between the myostracum buried in upper folia, and the bottom folia was identified as chitin. The transitional zone in the interface between the adductor muscle scar and folia are verified. The myostracum disappeared at the edge of the scar of the posterior side. From this study, the entire structure of the myostracum from the adult oyster shell of Crassostrea gigas could be proposed.

    Representatives of the genera Gordona and Tsukamurella together with related actinomycetes were the subject of chemotaxonomic, numerical taxonomic and DNA homology studies. In the numerical analysis the organisms were examined for 116 unit characters and the data sorted using the simple matching, Jaccard and pattern coefficients; clustering was achieved using the unweighted pair group method with arithmetic averages algorithm. The numerical groupings were not affected by the statistics used or by test error, estimated at 1.9%. The numerical taxonomic data supported the integrity of the four validly described species of Gordona but indicated that the genus Tsukamurella might encompass a species in addition to Tsukamurella paurometabola. The putative new strains had chemical, enzymic, nutritional and tolerance properties consistent with their assignment to the genus Tsukamurella and formed a DNA homology group corresponding to the one formed by the Tsukamurella paurometabola strains. It is proposed that the new taxon be assigned to the genus Tsukamurella as Tsukamurella wratislaviensis.

    The indirect effect of anthropogenic aerosols, wherein aerosol particles are thought to increase cloud droplet concentrations and cloud lifetime, is the most uncertain component of climate forcing over the past 100 years. Here, for the first time, we use a mechanistic treatment of droplet nucleation and a prognostic treatment of the number of cloud droplets to study the indirect aerosol effect from changes in carbonaceous and sulfate aerosols. Cloud droplet nucleation is parameterized as a function of total aerosol number concentration, updraft velocity and a shape parameter, which takes into account the mechanism, of sulfate aerosol formation, while cloud droplet number depends on the nucleation as well as on droplet sinks. Whereas previous treatments have predicted annual average indirect effects between -1 and -2 W/sq m, we obtain an indirect aerosol effect between -0.14 W/sq m and -0.42 W/sq m in the global mean.

    The second-order nonlinear optical susceptiblities βuk, βμ and third-order non-linear optical susceptibilities γijkl, (γ〉 of a series of the novel push-pull multi-ring eletro- photo polymer intermediates have been calculated. The influences of molecular structure, donor, acceptor and the frequency of external field onβandγ, and the relationship betweenγand the number of thiophene rings ( i. e. conjugated chain length) have been studied using INDO/SCI methods combined with sum-over-state(SOS) formula. The calculated results show that γ is proportional to 2.69 power of the chain length of the conjugated molecular bonds when the length is not quite long.

    A case study is reported whereby an individual with known sulfite and sulfonamide allergies develops hypersensitivity to taurine above a threshold level as well as to the non-nutritive sweetener acesulfame potassium, compounds that are not normally associated with allergic reactions. Sulfites, sulfonamides, taurine and acesulfame potassium all contain a SO3 moiety. Challenge tests provide evidence for the hypersensitivities to taurine and acesulfame potassium. The subject is also allergic to thiuram mix and thimerosal, sulfur containing compounds, as well as to various food products. This may be the first case where hypersensitivities to taurine and acesulfame potassium have been documented and reported. Several mechanistic explanations are provided for the untoward reactions to taurine and acesulfame potassium. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

  13. Including the urban heat island in spatial heat health risk assessment strategies: a case study for Birmingham, UK

    Thornes John E

    2011-06-01

    Full Text Available Abstract Background Heatwaves present a significant health risk and the hazard is likely to escalate with the increased future temperatures presently predicted by climate change models. The impact of heatwaves is often felt strongest in towns and cities where populations are concentrated and where the climate is often unintentionally modified to produce an urban heat island effect; where urban areas can be significantly warmer than surrounding rural areas. The purpose of this interdisciplinary study is to integrate remotely sensed urban heat island data alongside commercial social segmentation data via a spatial risk assessment methodology in order to highlight potential heat health risk areas and build the foundations for a climate change risk assessment. This paper uses the city of Birmingham, UK as a case study area. Results When looking at vulnerable sections of the population, the analysis identifies a concentration of "very high" risk areas within the city centre, and a number of pockets of "high risk" areas scattered throughout the conurbation. Further analysis looks at household level data which yields a complicated picture with a considerable range of vulnerabilities at a neighbourhood scale. Conclusions The results illustrate that a concentration of "very high" risk people live within the urban heat island, and this should be taken into account by urban planners and city centre environmental managers when considering climate change adaptation strategies or heatwave alert schemes. The methodology has been designed to be transparent and to make use of powerful and readily available datasets so that it can be easily replicated in other urban areas.

    A direct comparison of three commercially-available column flotation technologies, i.e., Jameson Cell, Microcel, and Packed-Column, has been conducted using a {minus}100 mesh Illinois No. 5 flotation feed coal sample. The separation performance of each flotation technology was optimized and their performance levels compared on the basis of both ash rejection, sulfur rejection, and throughput capacities. A parametric study using a statistically-designed experimental program was conducted to optimize the critical operating parameter values of each column. The ultimate performance curves for each column were generated by conducting additional tests using the optimized operating parameter values. The throughput capacity of each flotation cell was determined by conducting tests over a range of feed rates at the maximum superficial gas rate while maintaining the other parameters at their optimum values. The separation performance achieved by each of the three flotation cells was found to be comparable to the idealistic flotation performance predicted by release analysis. However, the fraction of wash water reporting to tailings (bias factor) was found to be critical in achieving the near idealistic performance. The bias factor required for the Packed-Column was found to be less than that required by the other two flotation cells. The sulfur rejection achieved by the Microcel and the Packed-Column were found to be greater than that achieved by the Jameson Cell and all three produced sulfur rejections exceeding the values obtained from release analysis. The throughput capacity, on the other hand, differed among the three flotation columns. The Jameson Cell and the Microcel were found to have comparable throughput capacities while the Packed-Column was found to have a lower capacity.

    Full Text Available The study addresses the issues of skills enhancement that need be implemented in three distinct phases of enterprise development. Phase I is the developmental phase where potential entrepreneurs are provided with skills needed for venture take-off or start-up. Phase II is the enterprise creation phase while Phase III is the market development phase. This paper also discusses the multiple roles of the Techno Center during each of these distinct phases. Based on the analysis, the study found that there are gaps across industrial sub-sectors in term of various skills needed to create sustainable enterprise and entrepreneur development. Those gaps are cognitive, interpersonal, technical, creativity, computation, communication, intrapersonal, conceptual, managerial, analytical, technological, acoustic, design, self-management, innovative, basic managerial, supervisory, and marketing. The Techno Centre Enterprise Development Model highlights the central and multiple roles required of The Techno Centre in order to effectively provide support and services during various phases of enterprise development. The services include skill development, networking and linkages services; technology transfer and consultancy services; advisory services; and after-care services have different contents at different stages of the enterprise development.Key words: technology park, sustainable enterprise, technology transfer

    The goal of this work is to study rural-urban migration in the early stages of industrialization. We use an agent-based model and take into account the existence of informal and formal workers on the urban sector and possible migration movements, dependent on the agents' social and private utilities. Our agents are place on vertices of a square lattice, such that each vertex has only one agent. Rural, urban informal and urban formal workers are represented by different states of a three-state Ising model. At every step, a fraction a of the agents may change sectors or migrate. The total utility of a given agent is then calculated and compared to a random utility, in order to check if this agent turns into an actual migrant or changes sector. The dynamics is carried out until an equilibrium state is reached and equilibrium variables are then calculated and compared to available data. We find that a generalized Harris-Todaro condition is satisfied [1] on these equilibrium regimes, i.e, the ratio between expected wages between any pair of sectors reach a constant value.

    CD44 is a cell adhesion molecule involved in tumour growth and progression. This study was undertaken to evaluate the expression of CD44 standard protein in a series of 54 colorectal adenocarcinomas in correlation with cathepsin D immunoreactivity and some other clinicopathological variables. Formalin-fixed and paraffin-embedded tissues were investigated with anti-CD44 standard protein and anti-cathepsin D antibody. Immunolocalisation of CD44 protein and cathepsin D was performed using LSAB method. 13 (41.9%) out of 31 carcinomas without lymph-node metastases had positive CD44 expression, whereas only 6 (26.1%) out of 23 carcinomas with lymph-node metastases were found positive for CD44 expression. CD44 expression in carcinomas was positively correlated with tumour cells cathepsin D (p<0.01) immunostaining. statistically significant correlation was found between the expression of CD44 standard protein and the tumour site, age and sex of the patients. These results suggest that the standard-type CD44 protein lymph-node metastases, probably with cooperation of cathepsin D.

    We present the abundance analyses for the neutron-capture elements, and discuss the observed abundance distributions in very metal-poor stars with excesses of r-process elements. As has been found by previous abundance studies, the star-to-star scatter in the abundances of neutron-capture elements are very large. The abundance patterns of the heavy neutron-capture elements (56 $\\leq$ Z $\\leq$ 70) in seven objects with moderate to large excesses of the neutron-capture elements are similar to that of the solar system r-process component. These results strongly suggest that the heavy neutron-capture elements in these objects are primarily synthesized by the r-process. On the other hand, the abundance ratios of the light neutron-capture elements (38 $\\leq$ Z $\\leq$ 46) exhibit a rather large dispersion. Our inspection of the correlation between Sr and Ba abundances in very metal-poor stars reveals that the dispersion of the Sr abundances clearly decreases with increasing Ba abundance. This results support previou...

    A total of 20 patients with cold antibody hemolytic anemia were evaluated in a retrospective study of them, 15 had a monoclonal gammopathy of unknown significance (MGUS): 14 with MGUS of immunoglobulin M (IgM) subtype and 1 with immunoglobulin G subtype. One patient had smoldering Waldenström's macroglobulinemia, but four patients had no monoclonal protein and no evidence of lymphoma. However, in three of these patients, we were able to demonstrate a (mono-)clonal rearrangement of their immunoglobulin heavy and/or light chains. Of the 20 patients, 5 had IgHV34 nucleotide sequence indicating that the antibody was directed against the "I" antigen. Two patients exhibited a progressive increase of IgM over time, however without increasing hemolytic activity. Moreover, in two patients with long-term follow-up, we were able to correlate recurrent hemolytic activity with low environmental temperatures. Among four patients treated with rituximab, all four responded to treatment. However, treatment effect was only transient in all of them.

    The severity criterion used in DSM-5 for bulimia nervosa (BN) was investigated in 214 individuals referred for treatment at a regional eating disorders service in the UK. In addition to comparing eating disorder symptoms, impairment secondary to these symptoms was also assessed. According to guidance in DSM-5, 94 individuals were classified as mild (43.9%), 70 as moderate (32.7%), 32 as severe (15.0%), and 8 as extreme (3.7%) levels of BN severity. Due to small numbers in the latter two groups, it was necessary to combine these to form one 'severe/extreme' group. Analyses on these three groups suggested no group effect on demographic variables but differences were seen on measures of eating pathology, psychological distress, and psychosocial impairment between the mild group and other groups. Individuals in the moderate and severe/extreme groups scored comparably on most measures of pathology and impairment. The results are broadly consistent with past studies on community samples although together question the demarcation between moderate and more severe groups of individuals with BN.

    A companion report, DOE/ET-0064/1, presents a geographic, cultural, and demographic profile of the Tennessee Valley Region study area. This report describes the calculations of radionuclide release and transport and of the resultant dose to the regional population, assuming a projected installed capacity of 220,000 MW in the year 2000, of which 144,000 MW would be nuclear. All elements of the fuel cycle were assumed to be in operation. The radiological dose was calculated as a one-year dose based on ingestion of 35 different food types as well as for nine non-food pathways, and was reported as dose to the total body and for six specific organs for each of four age groups (infant, child, teen, and adult). Results indicate that the average individual would receive an incremental dose of 7 x 10/sup -4/ millirems in the year 2000 from the operation of nuclear facilities within and adjacent to the region, five orders of magnitude smaller than the dose from naturally occurring radiation in the area. The major contributor to dose was found to be tritium, and the most significant pathways were immersion in air, inhalation of air, transpiration of tritium (absorption through the skin), and exposure radionuclide-containing soil. 60 references.

  2. Bipole-dipole interpretation with three-dimensional models (including a field study of Las Alturas, New Mexico)

    The bipole-dipole responses of three-dimensional (3D) prisms were studied using an integral equation numerical solution. Although response patterns are quite complex, the bipole-dipole method appears to be a useful, efficient means of mapping the areal distribution of resistivity. However, 3D modeling is required for quantitative interpretation. Computer time for our solution varies from negligible for small bodies to 6 minutes on a UNIVAC 1108 for the largest possible body (85 cubes). Bipole-dipole response varies significantly with bipole orientation and position, but simply changing the distance between the bipole and the body does not greatly affect the response. However, the response is complex and interpretation ambiguous if both transmitter electrodes are located directly over a body. Boundaries of shallow bodies are much better resolved than those of deep bodies. Conductive bodies produce false polarization highs that can confuse interpretation. It is difficult to distinguish the effects of depth and resistivity contrast, and, as with all electrical methods, depth extent is difficult to resolve. Interactive interpretation of bipole-dipole field results from a geothermal prospect in New Mexico illustrates the value of the 3D modeling technique.

    A radioreceptor assay has been established to measure the receptor affinities of numerous benzodiazepines in clinical use. The time course of receptor binding activity was studied by this method in the plasma of eight healthy subjects randomly treated with 1mg lormetazepam (Noctamid(R)), 2mg flunitrazepam (Rohypnol(R)), and 10mg diazepam (Valium(R)), and placebo on a cross-over basis. Blood samples were collected up to 154h after treatment. Receptor affinities of numerous benzodiazepines in vitro show good correlation with therapeutic human doses (r=0.96) and may be predictive of drug potency in man. Mean peak plasma levels of lormetazepam binding equivalents were 4.8+-1 ng/ml at 2h after lormetazepam, 7.2+-1.8 ng/ml at 8h after flunitrazepam, and 17.9+-2.7 ng/ml at 15h after diazepam. Plasma elimination halflives of benzodiazepine binding equivalents were 9.3, 23 and 63h, respectively. Slow elimination of benzodiazepine binding equivalents following flunitrazepam and diazepam may be due to persistent active metabolites.

    Cardiac myxoma usually occurs as a solitary mass, but occasionally develops as part of a familial syndrome, the Carney complex (CNC). Two thirds of CNC-associated cardiac myxomas exhibit mutations in PRKAR1A. PRKAR1A mutations occur in both familial and sporadic forms of CNC but have not been described in isolated (nonsyndromic) cardiac myxomas. A total of 127 consecutive cardiac myxomas surgically resected at Mayo Clinic (1993 to 2011) from 110 individuals were studied. Clinical, radiologic, and pathologic findings were reviewed. Of these, 103 patients had isolated cardiac myxomas, and 7 patients had the tumor as a component of CNC. Age and sex distributions were different for CNC (mean 26 y, range 14 to 44 y, 71% female) and non-CNC (mean 62 y, range 18 to 92 y, 63% female) patients. PRKAR1A immunohistochemical analysis (IHC) was performed, and myxoma cell reactivity was graded semiquantitatively. Bidirectional Sanger sequencing was performed in 3 CNC patients and 29 non-CNC patients, to test for the presence of mutations in all coding regions and intron/exon boundaries of the PRKAR1A gene. IHC staining showed that all 7 CNC cases lacked PRKAR1A antigenicity and that 33 (32%) isolated cardiac myxomas were similarly nonreactive. Of tumors subjected to sequencing analysis, 2 (67%) CNC myxomas and 9 (31%) non-CNC myxomas had pathogenic PRKAR1A mutations. No germline mutations were found in 4 non-CNC cases tested. PRKAR1A appears to play a role in the development of both syndromic and nonsyndromic cardiac myxomas. Routine IHC evaluation of cardiac myxomas for PRKAR1A expression may be useful in excluding a diagnosis of CNC.

    Although diet, physical activity (PA), sedentary behavior and sleep deprivation are factors that have been individually associated with insulin resistance (IR) in childhood, the combined effect of these lifestyle behaviors has not been examined yet. The current study aimed to examine the association of lifestyle patterns with IR, combining all these indices, in children. Socio-economic, demographic, anthropometric (body weight, height and waist circumference), biochemical (plasma glucose and serum insulin), clinical (pubertal stage) and lifestyle (dietary intake, PA level and sleeping habits) data were collected from a representative sample of 2026 children (50.1% girls) aged 9-13 years in Greece. Homeostasis model assessment (HOMA-IR) was calculated, and principal component analysis was used to identify lifestyle patterns, combining all these lifestyle indices. In multivariable regression analyses, the lifestyle pattern characterized by more screen time, shorter sleep duration and higher consumption of sugared beverages was positively associated with HOMA-IR (β=0.043; P=0.040), whereas the pattern characterized by more time spent on moderate-to-vigorous PA (MVPA) and more frequent eating occasions was inversely associated with HOMA-IR (β=-0.061; P=0.003). In logistic regression analyses, children with 72.2 min/day of MVPA and 5.05 eating occasions/day and children with 141.8 min/day of MVPA and 5.22 eating occasions/day were less likely of being insulin resistant based on HOMA-IR, compared with children with 20.0 min/day of MVPA and 4.09 eating occasions/day. A lifestyle pattern of >72 min of MVPA and 5 eating occasions/day was associated with reduced likelihood of IR in children.

    The project was launched to identify barriers to the implementation of renewable energy technologies (RETs) and explore measures to overcome the identified barriers. National institutions in Egypt, Ghana and Zimbabwe carried out the country studies based on the basic methodological framework provided by the UNEP Centre. The objectives of the project included strengthening institutional capacity for analysis and implementation of RET projects in the participating countries and bring out experiences on RETs barriers and removal measures for dissemination so that others can benefit from the knowledge so gained. An important highlight of the studies was involvement of stake holders in the process of identification of barriers and measures to remove them. A preliminary identification of relevant RETs for their countries was done by the country teams in the initial stage of the project. After that, national workshops involving various stake holders were held between July and September 1999 to discuss the RETs and barriers to their implementation. Based on the discussions, a few important RETs were identified for more detailed study. PV systems for rural electrification, solar water heating systems and large-scale biogas system were identified and analysed for barriers in the Egypt country study. Economic, information and policy barriers were identified as major barriers for these technologies. Solar water pumps, biogas and small hydro were the focus of study in Ghana. In this case also, economic, information and policy barriers were found to be the important barriers for the selected technologies. In the case of Zimbabwe, focus was on identification of primary and secondary barriers to RETs dissemination. The primary barriers included lack of capacity to develop proposals, lack of information for policy making and framework for information dissemination. The study concluded that the secondary barriers as seen and experienced by the stake holders are due to primary

    New technologies are an integral component of today's society and can complement existing suicide prevention programs. Here, we analyzed the use of new technologies in the prevention of suicide in 8 different European countries. The aim of this paper was to assess the opinions of professionals in incorporating such resources into the design of a suicide prevention program for the region of Zamora in Spain. This investigation, encompassed within the European project entitled European Regions Enforcing Actions against Suicide (EUREGENAS), includes 11 regions from 8 different countries and attempts to advance the field of suicide prevention in Europe. Using a specifically designed questionnaire, we assessed the opinions of 3 different groups of stakeholders regarding the use, frequency of use, facilitators, content, and format of new technologies for the prevention of suicide. The stakeholders were comprised of policy and public management professionals, professionals working in the area of mental health, and professionals related to the social area and non-governmental organizations (NGOs). A total of 416 participants were recruited in 11 regions from 8 different European countries. The utility of the new technologies was valued positively in all 8 countries, despite these resources being seldom used in those countries. In all the countries, the factors that contributed most to facilitating the use of new technologies were accessibility and free of charge. Regarding the format of new technologies, the most widely preferred formats for use as a tool for the prevention of suicide were websites and email. The availability of information about signs of alarm and risk factors was the most relevant content for the prevention of suicide through the use of new technologies. The presence of a reference mental health professional (MHP) was also considered to be a key aspect. The countries differed in the evaluations given to the different formats suggesting that the cultural

    The development of transportation systems that use new and sustainable energy technologies is of utmost importance due to the possible future shortfalls that current transportation modes will encounter because of increased volume and costs. The introduction and further research and development of new transportation and energy systems by materials researchers at the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) and the Department of Transportation are discussed in this Technical Memorandum. In this preliminary study, airship concepts were assessed for cargo transportation using various green energy technologies capable of 24-hour operation (i.e., night and day). Two prototype airships were successfully constructed and tested at LaRC to demonstrate their feasibility: one with commercially available solar cells for operation during the daytime and one with microwave rectennas (i.e., rectifying antennas) developed in-house for night-time operation. The test results indicate the feasibility of a cargo transportation airship powered by new green energy sources and wireless power technology. Future applications will exploit new green energy sources that use materials and devices recently developed or are in the process of being developed at LaRC. These include quantum well SiGe solar cells; low, mid-, and high temperature thermoelectric modules; and wireless microwave and optical rectenna devices. This study examines the need and development of new energy sources for transportation, including the current status of research, materials, and potential applications.

    Pediatric chronic illness care models are traditionally organized around acute episodes of care and may not meet the needs of patients and their families. Interventions that extend the patient-clinician interaction beyond the health care visit, allow for asynchronous and bidirectional feedback loops that span visits and daily life, and facilitate seamless sharing of information are needed to support a care delivery system that is more collaborative, continuous, and data-driven. Orchestra is a mobile health technology platform and intervention designed to transform the management of chronic diseases by optimizing patient-clinician coproduction of care. The aim of this study is to assess the feasibility, acceptability, and preliminary impact of the Orchestra technology and intervention in the context of pediatric chronic illness care. This study will be conducted in the cystic fibrosis and inflammatory bowel disease clinics at Cincinnati Children's Hospital Medical Center. We will enroll interested patients and their caregivers to work with clinicians to use the Orchestra technology platform and care model over a 6-month period. In parallel, we will use quality improvement methods to improve processes for integrating Orchestra into clinic workflows and patient/family lifestyles. We will use surveys, interviews, technology use data, and measures of clinical outcomes to assess the feasibility, acceptability, and preliminary impact of Orchestra. Outcome measures will include assessments of: (1) enrollment and dropout rates; (2) duration of engagement/sustained use; (3) symptom and patient-reported outcome tracker completion rates; (4) perceived impact on treatment plan, communication with the clinical team, visit preparation, and overall care; (5) changes in disease self-efficacy and engagement in care; and (6) clinical outcomes and health care utilization. Participant recruitment began in mid-2015, with results expected in 2017. Chronic disease management needs a

    Full Text Available This article analyzes the sensemaking processes of organizational identity and technological capabilities that are facilitators of innovation at New-Technology-Based Firms (NTBFs. The research proposal points out that in this kind of organization, the knowledge transferred by these processes simultaneously addresses two core aspects: their organizational identity and technological capabilities. From a theoretical point of view, our study links two conceptual frameworks (organizational identity and technological capabilities, rarely mentioned together in the preceding research. From a practical point of view, the findings identify these processes and suggest that in this kind of organization both take place simultaneously, which could help stakeholders improve their management. Hence, members and managers of these organizations should take these processes into account as a framework to achieve competitiveness and therefore success.

    Assistive technology services are essential for adapting assistive devices to the individual needs of users with disabilities. In this study, we attempted to apply three-dimensional (3D) printing technology to three actual cases, and to study its use, effectiveness, and future applications. We assessed the usefulness of 3D printing technology by categorizing its utilization after reviewing the outcomes of these case studies. In future work, we aim to gather additional case studies and derive information on using 3D printing technology that will enable its effective application in the process of assistive technology services.

    as for example Rouse, Schatzki and Reckwitz refrain from including the pragmatist legacy in their writings. This question would probably either be entirely speculative or maybe even not very interesting? Rather, I want to explore what these two apparently similar ways of theorizing do to the study of science...... to the normative evaluation of action, I show that the two intellectual traditions have much in common when it comes to what they do to STS studies. After this introduction to practice theory, my paper will proceed in the following steps. Firstly, I will briefly survey practice theoretical and pragmatist...

    Positron Doppler broadening experiments using variable-energy positron beams with positron implantation energy range 0-25 keV and 0-30 keV, respectively, have been performed on a selection of thin technological films. By measuring the spectrum of the 511 keV annihilation gamma-rays photopeak the profile of the Doppler broadening of the photopeak, due to the motion of the annihilating positron-electron pair, can be analysed. Varying the incident positron energy enables the positron t$ probe a sample at different depths which makes it possible to study samples by analysing the Doppler broadening of the photopeak as a function of positron depth. The Doppler broadening experiments on gallium nitride films with different crystallographic orientations revealed distortions in the Doppler broadened profile at low energies. The distortions were identified to be a consequence of significant para-positronium annihilation taking place near the sample surface. A parameter based on the proportion of positrons trapped at an...

    Mobile technologies have wide-scale reach and disseminability, but no known studies have examined mobile technologies as a stand-alone tool to improve obesity-related behaviors of at-risk youth. To test a 12-week mobile technology intervention for use and estimate effect sizes for a fully powered trial. Fifty-one low-income, racial/ethnic-minority girls aged 9-14 years were randomized to a mobile technology (n=26) or control (n=25) condition. Both conditions lasted 12 weeks and targeted fruits/vegetables (FVs; Weeks 1-4); sugar-sweetened beverages (SSBs; Weeks 5-8), and screen time (Weeks 9-12). The mobile intervention prompted real-time goal setting and self-monitoring and provided tips, feedback, and positive reinforcement related to the target behaviors. Controls received the same content in a written manual but no prompting. Outcomes included device utilization and effect size estimates of FVs, SSBs, screen time, and BMI. Data were collected and analyzed in 2011-2012. Mobile technology girls used the program on 63% of days and exhibited trends toward increased FVs (+0.88, p=0.08) and decreased SSBs (-0.33, p=0.09). The adjusted difference between groups of 1.0 servings of FVs (p=0.13) and 0.35 servings of SSBs (p=0.25) indicated small to moderate effects of the intervention (Cohen's d=0.44 and -0.34, respectively). No differences were observed for screen time or BMI. A stand-alone mobile app may produce small to moderate effects for FVs and SSBs. Given the extensive reach of mobile devices, this pilot study demonstrates the need for larger-scale testing of similar programs to address obesity-related behaviors in high-risk youth.

    A diverse suite of numerical simulators is currently being applied to predict or understand the performance of enhanced geothermal systems (EGS). To build confidence and identify critical development needs for these analytical tools, the United States Department of Energy, Geothermal Technologies Office has sponsored a Code Comparison Study (GTO-CCS), with participants from universities, industry, and national laboratories. A principal objective for the study was to create a community forum for improvement and verification of numerical simulators for EGS modeling. Teams participating in the study were those representing U.S. national laboratories, universities, and industries, and each team brought unique numerical simulation capabilities to bear on the problems. Two classes of problems were developed during the study, benchmark problems and challenge problems. The benchmark problems were structured to test the ability of the collection of numerical simulators to solve various combinations of coupled thermal, hydrologic, geomechanical, and geochemical processes. This class of problems was strictly defined in terms of properties, driving forces, initial conditions, and boundary conditions. Study participants submitted solutions to problems for which their simulation tools were deemed capable or nearly capable. Some participating codes were originally developed for EGS applications whereas some others were designed for different applications but can simulate processes similar to those in EGS. Solution submissions from both were encouraged. In some cases, participants made small incremental changes to their numerical simulation codes to address specific elements of the problem, and in other cases participants submitted solutions with existing simulation tools, acknowledging the limitations of the code. The challenge problems were based on the enhanced geothermal systems research conducted at Fenton Hill, near Los Alamos, New Mexico, between 1974 and 1995. The problems

    The technology-driven medication process is complex, involving advanced technologies, patient participation and increased safety measures. Medication administration errors are frequently reported, with nurses implicated in 26-38% of in-hospital cases. This points to the need for new ways of educating nursing students in today's medication administration. To explore nursing students' experiences and competences with the technology-driven medication administration process. 16 pre-graduate nursing students were included in two focus group interviews which were recorded, transcribed and analyzed using the systematic horizontal phenomenological-hermeneutic template methodology. The interviews uncovered that understanding the technologies; professionalism and patient safety are three crucial elements in the medication process. The students expressed positivity and confidence in using technology, but were fearful of committing serious medication errors. From the nursing students' perspective, experienced nurses deviate from existing guidelines, leaving them feeling isolated in practical learning situations. Having an unclear nursing role model for the technology-driven medication process, nursing students face difficulties in identifying and adopting best practices. The impact of using technology on the frequency, type and severity of medication errors; the technologies implications on nursing professionalism and the nurses ability to secure patient adherence to the medication process, still remains to be studied.

    NASA's Science Mission Directorate (SMD) and Space Technology Directorate (STMD) initiated a joint study to explore strategic approaches to the development of platform technologies and new measurement approaches in Earth, Planetary, Heliophysics, and Astrophysics science enabled by small satellites (including CubeSat class systems). The agency has made investments though various solicitations within SMD and STMD, but as system capabilities continue to grow and as exploration concepts become more ambitious there was a need to formally asses the role Smallsats could play from technology maturation through Decadal Survey science in a coordinated fashion within the parameters of reliability, cost, design time and measurement requirement assessment among other topics. This talk will review the activities of the study team as well as its findings in the context of the benefits a small satellite program could contribute to multiple aspects of NASA's scientific and technology development objectives.

  12. A Study of Scientometric Methods to Identify Emerging Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Abercrombie, Robert K [ORNL; Udoeyop, Akaninyene W [ORNL

    2011-01-01

    This work examines a scientometric model that tracks the emergence of an identified technology from initial discovery (via original scientific and conference literature), through critical discoveries (via original scientific, conference literature and patents), transitioning through Technology Readiness Levels (TRLs) and ultimately on to commercial application. During the period of innovation and technology transfer, the impact of scholarly works, patents and on-line web news sources are identified. As trends develop, currency of citations, collaboration indicators, and on-line news patterns are identified. The combinations of four distinct and separate searchable on-line networked sources (i.e., scholarly publications and citation, worldwide patents, news archives, and on-line mapping networks) are assembled to become one collective network (a dataset for analysis of relations). This established network becomes the basis from which to quickly analyze the temporal flow of activity (searchable events) for the example subject domain we investigated.

  13. A bridge between conceptual frameworks sciences, society and technology studies

    CERN Document Server

    2015-01-01

    This book analyzes scientific problems within the history of physics, engineering, chemistry, astronomy and medicine, correlated with technological applications in the social context. When and how is tension between disciplines explicitly practised? What is the conceptual bridge between science researches and the organization of technological researches in the development of  industrial applications?  The authors explain various ways in which the sciences allowed advanced modelling on the one hand, and the development of new technological ideas on the other hand. An emphasis on the role played by mechanisms, production methods and instruments bestows a benefit on historical and scientific discourse: theories, institutions, universities, schools for engineers, social implications as well.  Scholars from different traditions discuss the emerging style of thinking in methodology and, in theoretical perspective, aim to gather and re-evaluate the current thinking on this subject. It brings together contribution...

    The efforts in this project are directed toward three areas: (1) novel catalyst (supported and unsupported) research and development, (2) study and optimization of major operating parameters (specifically pressure), and (3) coal/waste coprocessing. The novel catalyst research and development activity has involved testing supported catalysts, dispersed catalysts, and use of catalyst testing units to investigate the effects of operating parameters (the second area) with both supported and unsupported catalysts. Several supported catalysts were tested in a simulated first stage coal liquefaction application at 404{degrees}C during this performance period. A Ni-Mo hydrous titanate catalyst on an Amocat support prepared by Sandia National laboratories was tested. Other baseline experiments using AO-60 and Amocat, both Ni-Mo/Al{sub 2}O{sub 3} supported catalysts, were also made. These experiments were short duration (approximately 12 days) and monitored the initial activity of the catalysts. The results of these tests indicate that the Sandia catalyst performed as well as the commercially prepared catalysts. Future tests are planned with other Sandia preparations. The dispersed catalysts tested include sulfated iron oxide, Bayferrox iron oxide (iron oxide from Miles, Inc.), and Bailey iron oxide (micronized iron oxide from Bailey, Inc.). The effects of space velocity, temperature, and solvent-to-coal ratio on coal liquefaction activity with the dispersed catalysts were investigated. A comparison of the coal liquefaction activity of these catalysts relative to iron catalysts tested earlier, including FeOOH-impregnated coal, was made. These studies are discussed.

    Background Nowadays, mobile technologies are part of everyday life, but the lack of instruments to assess their acceptability for the management of chronic diseases makes their actual adoption for this purpose slow. Objective The objective of this study was to develop a survey instrument for assessing patients’ attitude toward and intention to use mobile technology for diabetes mellitus (DM) self-management, as well as to identify sociodemographic characteristics and quality of life factors that affect them. Methods We first conducted the documentation and instrument design phases, which were subsequently followed by the pilot study and instrument validation. Afterward, the instrument was administered 103 patients (median age: 37 years; range: 18–65 years) diagnosed with type 1 or type 2 DM, who accepted to participate in the study. The reliability and construct validity were assessed by computing Cronbach’s alpha and using factor analysis, respectively. Results The instrument included statements about the actual use of electronic devices for DM management, interaction between patient and physician, attitude toward using mobile technology, and quality of life evaluation. Cronbach’s alpha was 0.9 for attitude toward using mobile technology and 0.97 for attitude toward using mobile device applications for DM self-management. Younger patients (Spearman’s ρ=−0.429; P<0.001) with better glycemic control (Spearman’s ρ=−0.322; P<0.001) and higher education level (Kendall’s τ=0.51; P<0.001) had significantly more favorable attitude toward using mobile assistive applications for DM control. Moreover, patients with a higher quality of life presented a significantly more positive attitude toward using modern technology (Spearman’s ρ=0.466; P<0.001). Conclusion The instrument showed good reliability and internal consistency, making it suitable for measuring the acceptability of mobile technology for DM self-management. Additionally, we found that even

    The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government

    The life cycle of technology is one of the most important indexes to weigh up the risk of the investment to neo-tech. There are so many uncertainties because it is conditioned by a lot of factors, we can not make a rational forecasting by traditional assessment method. So this paper gives a conprehensive consideration to the factors that influence production and makes some modification to production function, and establishes the life cycle of technology assessmet model by the method of fuzzy mathematics. So it quantifies the risk of investment. We can take it as one foundational index for the decision making of the investment.

    The purpose of this Technology Installation Review is to provide an overview of hybrid geothermal heat pump systems. It presents the results of recent research on these systems, looks at system types, energy savings, maintenance considerations, and measured technology performance from several examples. Using the ground as a thermal energy source and/or a heat sink for heat pumps has long been recognized to have a number of advantages over the similar use of ambient air. Ground temperatures at about 3-ft depth or lower are much less variable than ambient air temperatures. Further, soil or rock at these depths is usually warmer than ambient air during the coldest winter months and cooler than ambient air during the summer months. This fact leads directly to cooler condensation temperatures (during cooling operation) and warmer evaporating temperatures (during heating) for a heat pump with consequent improved energy efficiency. It also results in increased heating and cooling capacity at extreme temperatures, thereby reducing or eliminating the need for auxiliary heat.

    Hong, Lei; Mi, Chenglong; Wu, Gang

    2008-03-01

    It is easy to produce molten dross by using traditional laser cutting technology in laser cutting silicon steel sheet. The main reason is that oxidizing reaction will take place inevitably by using oxygen as aided gas, so high pressure and high purity N II or inert gases is used as aided cutting gas in laser cutting process. Although the cut quality is improved, the cutting efficiency is dropped because of the lack of energy resulting from an exothermic oxidation reaction. A fire new laser cutting technology by using an additional nozzle put under the workpiece that will form lateral gas flow to control the direction of the flowing dross gas is raised. In this technology oxygen is still used as aided gas, the laser power is reduced and the cut is fine. The experiments prove that by controlling the technical parameter reasonably, glossy and dross-free cutting kerfs are obtained. The gas flow acting under the workpiece is simulated by Finite Element Method (FEM). The varieties of pneumatic fields when the additional nozzle is in different degree and flow velocity are analyzed, which provides academic basis for controlling the flowing direction of the dross gas more reasonably. This laser cutting technology is practical and feasible.

  19. Study of sticky rice-lime mortar technology for the restoration of historical masonry construction.

    Yang, Fuwei; Zhang, Bingjian; Ma, Qinglin

    2010-06-15

    Replacing or repairing masonry mortar is usually necessary in the restoration of historical constructions, but the selection of a proper mortar is often problematic. An inappropriate choice can lead to failure of the restoration work, and perhaps even further damage. Thus, a thorough understanding of the original mortar technology and the fabrication of appropriate replacement materials are important research goals. Many kinds of materials have been used over the years in masonry mortars, and the technology has gradually evolved from the single-component mortar of ancient times to hybrid versions containing several ingredients. Beginning in 2450 BCE, lime was used as masonry mortar in Europe. In the Roman era, ground volcanic ash, brick powder, and ceramic chip were added to lime mortar, greatly improving performance. Because of its superior properties, the use of this hydraulic (that is, capable of setting underwater) mortar spread, and it was adopted throughout Europe and western Asia. Perhaps because of the absence of natural materials such as volcanic ash, hydraulic mortar technology was not developed in ancient China. However, a special inorganic-organic composite building material, sticky rice-lime mortar, was developed. This technology was extensively used in important buildings, such as tombs, in urban constructions, and even in water conservancy facilities. It may be the first widespread inorganic-organic composite mortar technology in China, or even in the world. In this Account, we discuss the origins, analysis, performance, and utility in historic preservation of sticky rice-lime mortar. Mortar samples from ancient constructions were analyzed by both chemical methods (including the iodine starch test and the acid attack experiment) and instrumental methods (including thermogravimetric differential scanning calorimetry, X-ray diffraction, Fourier transform infrared, and scanning electron microscopy). These analytical results show that the ancient masonry

    To compare different processing technologies of Aconiti Kusnezoffii Radix, and to optimize a kind of "low toxicity and high efficiency", simple and practical processing technology for Aconiti Kusnezoffii Radix. HPLC method was used to determine the content of six kinds of alkaloids, and titration method to determine the content of total alkaloids. These contents combined with production were used to evaluate the modern processing technologies of Aconiti Kusnezoffii Radix. There was serious drain of Aconitum alkaloids after treated by soaking, and the loss rates of the content of monoester alkaloids, diester alkaloids and total alkaloid were 20.97%, 31.13% and 14.57%, respectively. The content of alkaloids could maximize the retention using wetting method, the best methods for reducing poison were atmospheric pressure and high pressure steaming cooking methods, and its total diester alkaloids content was too low to be detected, the contents of alkaloids in samples of two kinds of high-temperature baking were 0.6903 mg/g and 0.5575 mg/g, which were higher than the requirement of Chinese Pharmacopoeia. The content of monoester alkaloids was 0.6336 - 2.2721 mg/g of 10 kinds of processing technologies, between which there were nine kinds of processing technologies beyong the Chinese Pharmacopoeia requirement of 0.7 mg/g, while the total alkaloids content was 7.8019 - 11.2078 mg/g. The best method for reducing poison is high-pressure steaming, whose content of diester alkaloids can reach the Chinese Pharmacopoeia requirement after treatment of wet autoclaved products, with higher content of total alkaloids. It is simple, controllable, and suitable for processing of Aconiti Kusnezoffii Radix.
