    2000-04-01

    Since October 1979, Korea had implemented a petroleum project fund dues system to actively prepare for unstable international petroleum condition. However, as the size of operating a petroleum project fund was bigger and the influence of government on this fund became powerful, it was inserted in the government tax revenues as a {sup S}pecial account for energy and resource project{sup i}n March 1994 and its name was changed to import dues. In this study, it discusses the facts of import dues system, which exists only in Korea, and its policy directions since this system has been reviewed due to the economic development, liberalization of petroleum industry and inequity between alternative energy sources. 4 tabs.

    Previous studies have demonstrated that the rising mortality due to mesothelioma and asbestosis can be predicted from historic asbestos usage. Mortality due to idiopathic pulmonary fibrosis (IPF) is also rising, without any apparent explanation. To compare mortality due to these conditions and examine the relationship between mortality and national asbestos imports. Mortality data for IPF and asbestosis in England and Wales were available from the Office for National Statistics. Data for mesothelioma deaths in England and Wales and historic UK asbestos import data were available from the Health & Safety Executive. The numbers of annual deaths due to each condition were plotted separately by gender, against UK asbestos imports 48 years earlier. Linear regression models were constructed. For mesothelioma and IPF, there was a significant linear relationship between the number of male and female deaths each year and historic UK asbestos imports. For asbestosis mortality, a similar relationship was found for male but not female deaths. The annual numbers of deaths due to asbestosis in both sexes were lower than for IPF and mesothelioma. The strength of the association between IPF mortality and historic asbestos imports was similar to that seen in an established asbestos-related disease, i.e. mesothelioma. This finding could in part be explained by diagnostic difficulties in separating asbestosis from IPF and highlights the need for a more accurate method of assessing lifetime occupational asbestos exposure. © Crown copyright 2015.

  4. Importance of international standards on hydrogen technologies

    International Nuclear Information System (INIS)

    Bose, T.K.; Gingras, S.

    2001-01-01

    This presentation provided some basic information regarding standards and the International Organization for Standardization (ISO). It also explained the importance of standardization activities, particularly ISO/TC 197 which applies to hydrogen technologies. Standards are established by consensus. They define the minimum requirements that will ensure that products and services are reliable and effective. Standards contribute to the elimination of technical barriers to trade (TBT). The harmonization of standards around the world is desirable in a free trade environment. The influence of the TBT on international standardization was discussed with particular reference to the objectives of ISO/TC 197 hydrogen technologies. One of the priorities for ISO/TC 197 is a hydrogen fuel infrastructure which includes refuelling stations, fuelling connectors, and storage technologies for gaseous and liquid hydrogen. Other priorities include an agreement between the International Electrotechnical Commission (IEC) and the ISO, in particular the IEC/TC 105 and ISO/TC 197 for the development of fuel cell standards. The international standards that have been published thus far include ISO 13984:1999 for liquid hydrogen, land vehicle fuelling system interface, and ISO 14687:1999 for hydrogen fuel product specification. Standards are currently under development for: liquid hydrogen; airport hydrogen fuelling facilities; gaseous hydrogen blends; basic considerations for the safety of hydrogen systems; gaseous hydrogen and hydrogen blends; and gaseous hydrogen for land vehicle filling connectors. It was concluded that the widespread use of hydrogen is dependent on international standardization

    2010-01-01

    A wide range of energy technologies appears to be needed for the United States to meet its energy goals. A method is developed that relates the uncertainty of technological progress in eleven technology areas to the achievement of CO 2 mitigation and reduced oil dependence. We conclude that to be confident of meeting both energy goals, each technology area must have a much better than 50/50 probability of success, that carbon capture and sequestration, biomass, battery electric or fuel cell vehicles, advanced fossil liquids, and energy efficiency technologies for buildings appear to be almost essential, and that the success of each one of the 11 technologies is important. These inferences are robust to moderate variations in assumptions.

  10. Dependent convergence: the importation of technological hazards by semiperipheral countries.

    Science.gov (United States)

    Siqueira, C E; Levenstein, C

    2000-01-01

    This article complements the substantial body of literature produced over the last three decades on the export of hazards from developed countries to developing countries. After reviewing the central arguments proposed by this literature, the authors add to the debate by focusing on the role of national actors in the importation of these hazards, based on the experience of late 1970s' developments in the petrochemical industry in Brazil. The Brazilian case indicates that social struggles and/or interactions among actors in developing and developed nations determine to what extent hazardous technologies are imported without environmental controls and to what extent their hazardous effects are controlled by these nations. This study suggests that the future development of a more inclusive theory of export-import of hazardous technologies and products should take into account the dialectical relationship established between social actors internal to the exporting and importing countries.

    Full Text Available Aim: To analyze the factors associated with morbidity and mortality rates as well as to evaluate economic losses due to important diseases of bovines, viz. mastitis, HS and surra in Purvanchal Region of Uttar Pradesh. Materials and Methods: A sample of 300 livestock owners were selected from each of five divisions of Purvanchal region of the state of Uttar Pradesh using multistage stratified sampling with simple random sampling without replacement at village level. The morbidity, mortality and case fatality rates due to different diseases were determined using standard statistical indices. Association between cattle morbidity and mortality rates and different factors was calculated by χ2 Test. The total economic loss due to diseases in bovines was worked out as sum of mortality loss, loss in milk yield and cost of treatment of affected animals. Results: The overall morbidity rates of mastitis, HS and surra in cattle and buffaloes were 15.5%, 7.1% and 5.3%, respectively. The mortality and case fatality due to HS was found higher in the young calves as compared to the adults in case of both buffaloes and cattle. Mortality and case fatality due to surra was greater in the adult animals as compared to the younger ones in case of both buffaloes and cattle. Total losses due to mastitis per lactation in ND cow, CB cow and buffalo were INR 868.34, INR 1, 314.10 and INR 1, 272.36, respectively. Total losses due to HS per animal in ND cows, CB cows and buffaloes were INR 2, 355.78, INR 3, 228.52 and INR 4, 262.57, respectively. Total losses due to surra per animal in ND cow, CB cow and buffalo were INR 3, 328.18, INR 6, 193 and INR 9, 872.33, respectively. Conclusion: The study thus revealed significant losses due to diseases in large ruminants on. There is thus ample scope for preventive measures to control the disease bovines.

  17. Potential displacement of petroleum imports by solar energy technologies

    1980-05-01

    The United States currently imports close to half of its petroleum requirements. This report delineates the economic, social, and political costs of such a foreign oil dependency. These costs are often intangible, but combined they clearly constitute a greater price for imported petroleum than the strictly economic cost. If we can assume that imported oil imposes significant socioeconomic costs upon the American economy and society, one way to reduce these costs is to develop alternative, domestic energy sources - such as solar energy technologies - which can displace foreign petroleum. The second half of this report estimates that by the year 2000, solar energy technologies can displace 3.6 quads of petroleum. This figure includes solar energy applications in utilities, industrial and agricultural process heat, and transportation. The estimate can be treated as a lower bound; if the United States were to achieve the proposed goal of 20 quads by 2000, the amount of displaced oil probably would be greater. Although all the displaced oil would not be imported, the reduction in imported petroleum would relieve many of the conditions that increase the present cost of foreign oil to the American consumer.

  19. Wind power costs expected to decrease due to technological progress

    2017-01-01

    The potential for future cost reductions in wind power affects adoption and support policies. Prior analyses of cost reductions give inconsistent results. The learning rate, or fractional cost reduction per doubling of production, ranges from −3% to +33% depending on the study. This lack of consensus has, we believe, contributed to high variability in forecasts of future costs of wind power. We find that learning rate can be very sensitive to the starting and ending years of datasets and the geographical scope of the study. Based on a single factor experience curve that accounts for capacity factor gains, wind quality decline, and exogenous shifts in capital costs, we develop an improved model with reduced temporal variability. Using a global adoption model, the wind-learning rate is between 7.7% and 11%, with a preferred estimate of 9.8%. Using global scenarios for future wind deployment, this learning rate range implies that the cost of wind power will decline from 5.5 cents/kWh in 2015 to 4.1–4.5 cents/kWh in 2030, lower than a number of other forecasts. If attained, wind power may be the cheapest form of new electricity generation by 2030, suggesting that support and investment in wind should be maintained or expanded. - Highlights: • Expectations for cost reductions in wind power is important for policy. • Wind learning rates are sensitive to data time period and regional choice. • We develop improved wind cost model with much reduced variability. • New model gives global wind learning rates between 7.7%-11%.

  2. Carbon dioxide emissions due to Swedish imports and consumption: estimates using different methods

    Carlsson-Kanyama, Annika; Assefa, Getachew; Wadeskog, Anders

    2007-04-01

    Global trade of products and services challenges the traditional way in which emissions of carbon dioxide are declared and accounted for. Instead of only considering territorial emissions there are now strong reasons to determine how the carbon dioxide emitted in the production of imports are partitioned around the world and how the total emissions change for a country's final consumption compared to final production. In this report results from four different methods of calculating the total carbon dioxide emissions from Sweden's overall consumption are presented. Total carbon dioxide emissions for Sweden's final consumption vary from 57 to 109 M tons during one year depending on the methodology. The four methods used for estimating these emissions give results of 57, 61, 68 and 109 Mton of carbon dioxide. Two methods are based on information concerning Sweden's imports and our national production of goods and services excluding production that is exported while two methods are based on final consumer expenditures. Three of the methods use mainly emission data from Sweden while one method depends entirely upon emission data from Sweden's trading partners. The last method also gives the highest emissions level, 109 Mton of carbon dioxide. The calculations performed here can be compared to the emissions reported by Sweden, 54 Mton of carbon dioxide per year. Our estimates give per capita emission levels of between 6,3 and 12 tons of carbon dioxide per year. The estimate of 12 tons per capita is a result of using emissions data from Sweden's trading partners. The total emissions as a result of Sweden's imports are 26 or 74 M tons of carbon dioxide depending on how they are calculated. The lower figure is based upon the imports of today but with emissions as if everything was produced as in Sweden. The higher level is based upon using existing but partly inadequate international emission statistics. These levels can be compared to the about 35 M tons of carbon dioxide

    2014-05-15

    In this research, we developed a plan for experimental validation of one of the computer models developed for ER process modeling, i. e., the ERAD code. Several candidate surrogate materials are selected for the experiment considering the chemical and physical properties. Molten salt-based pyroprocessing technology is being examined internationally as an alternative to treat spent nuclear fuel over aqueous technology. The central process in pyroprocessing is electrorefining(ER) which separates uranium from transuranic elements and fission products present in spent nuclear fuel. ER is a widely used process in the minerals industry to purify impure metals. Studies of ER by using actual spent nuclear fuel materials are problematic for both technical and political reasons. Therefore, the initial effort for ER process optimization is made by using computer models. A number of models have been developed for this purpose. But as validation of these models is incomplete and often times problematic, the simulation results from these models are inherently uncertain.

    2008-01-01

    The shortfall in food and field crops due to bad weather and the incidence of insects and microbes during harvesting, handling and storage under non-suitable conditions, called the attention of researchers to try to minimize the damage happening and by various means, whether to develop sources of new food, such as producing nutritional fungi, or by following non-traditional methods of anti-microbes and insects such as the use of radiation as a safe and successful way to save the food without any toxic effects. Permits have been issued for food irradiation by many international organizations including IAEA, World Health Organization and FAO. Nutritional fungi is one of the food sources used as food fit for human consumption in various countries around the world due to their importance which includes many aspects: the nutritional and health value; medical significance; environmental importance and industrial importance. Nuclear technology has contributed in many of the developments in the production and conservation of nutritional fungi, notably, biological studies of nutritional fungi, production technology of fungus, the role of radiation in the preparation and improvement of the nutritional media, improvement of the fungus strains, the use of radiation in the conservation of nutritional fungi and the detection of irradiated nutritional fungus.

  7. The importance of heavy water in nuclear technology

    Gharib, A.G.

    2004-01-01

    Due to similarities of chemical and almost physical properties in H 2 O and D 2 O but differences in nuclear and particle peculiarities provide valuable application for D 2 O. To sustain a controlled chain reaction, the energy of neutrons produced by fission must be reduced through collisions with other nuclei, a process called moderation. A good moderator has a mass close to that of the neutron to maximize energy loss per collision and a very small neutron capture cross section to minimize unwanted nuclear reactions. Deuterium is far the best moderator, more than 80 times better than hydrogen and 30 times better than 12 C ir 18 O. Heavy water is almost as good as deuterium and has the distinct advantage of being a nonflammable liquid. Heavy water is also an excellent neutron reflector, and thus decreases the number of neutrons that escape the reactor core without participating in fission reactions. For this reason a feasibility study and subsequently a technical survey was carried out on engineering of a pilot scale plant. As the result of this studies, the know-how of heavy water production on basis of selected method including dual temperature isotopic exchange and distillation techniques developed. Subsequently the primary and almost detail engineering documents prepared on best knowledge of our own engineers without external contribution

    2008-09-01

    In this work, radiation induced damage mechanisms in deep submicron technology is resolved using finger gated-diodes (FGDs) as a radiation sensitive tool. It is found that these structures are simple yet efficient structures to resolve radiation induced damage in advanced CMOS processes. The degradation of the CMOS image sensors in deep-submicron technology due to γ-ray irradiation is studied by developing a model for the spectral response of the sensor and also by the dark-signal degradation as a function of STI (shallow-trench isolation) parameters. It is found that threshold shifts in the gate-oxide/silicon interface as well as minority carrier life-time variations in the silicon bulk are minimal. The top-layer material properties and the photodiode Si-SiO2 interface quality are degraded due to γ-ray irradiation. Results further suggest that p-well passivated structures are inevitable for radiation-hard designs. It was found that high electrical fields in submicron technologies pose a threat to high quality imaging in harsh environments.

  13. Mechanical damage due to corrosion of parts of pump technology and valves of LWR power installations

    International Nuclear Information System (INIS)

    Hron, J.; Krumpl, M.

    1986-01-01

    Two types are described of uneven corrosion of austenitic chromium-nickel steel: pitting and slit corrosion. The occurrence of slit corrosion is typical of parts of pumping technology and valves. The corrosion damage of austenitic chromium-nickel steels spreads as intergranular, transgranular or mixed corrosion. In nuclear power facilities with LWR's, intergranular corrosion is due to chlorides and sulphur compounds while transgranular corrosion is due to the presence of dissolved oxygen and chlorides. In mechanically stressed parts, stress corrosion takes place. The recommended procedures are discussed of reducing the corrosion-mechanical damage of pumping equipment of light water reactors during design, production and assembly.

    2012-09-01

    We develop a microeconomical model to investigate the impact of technological change onto production decisions of suppliers—modeling an effective feedback mechanism of the market. An important property—the time horizon of production planning—is related to the Kolmogorov entropy of the one-dimensional maps describing price dynamics. We simulate this price dynamics in an ensemble representing the whole macroeconomy. We show how this model can be used to support ongoing research in economic growth and incorporate the obtained microeconomic findings into the discussion about appropriate macroeconomic quantities such as the production function—thus effectively underpinning macroeconomics with microeconomical dynamics. From there we can show that the model exhibits different dynamical regimes (suggesting "phase transitions") with respect to an order parameter. The non-linear feedback under technological change was found to be the crucial mechanism. The implications of the obtained regimes are finally discussed.

    There is an increasing use of technology for teaching and learning in medical education but often the use of educational theory to inform the design is not made explicit. The educational theories, both normative and descriptive, used by medical educators determine how the technology is intended to facilitate learning and may explain why some interventions with technology may be less effective compared with others. The aim of this study is to highlight the importance of medical educators making explicit the educational theories that inform their design of interventions using technology. The use of illustrative examples of the main educational theories to demonstrate the importance of theories informing the design of interventions using technology. Highlights the use of educational theories for theory-based and realistic evaluations of the use of technology in medical education. An explicit description of the educational theories used to inform the design of an intervention with technology can provide potentially useful insights into why some interventions with technology are more effective than others. An explicit description is also an important aspect of the scholarship of using technology in medical education.

    2006-01-01

    Current semiconductor technology, the so-called the molecule reaction based semiconductor manufacturing, now faces a very severe standstill due to the drastic increase of gate leakage currents and drain leakage currents. Radical reaction based semiconductor manufacturing has been developed to completely overcome the current standstill by introducing microwave excited high density plasma with very low electron temperatures and without accompanying charge-up damage. The introduction of radical reaction based semiconductor manufacturing has made it possible to fabricate LSI devices on any crystal orientation Si substrate surface as well as (100) Si substrate surfaces, and to eliminate a very severe limitation to the antenna ratio in the circuit layout patterns, which is strictly limited to less than 100-200 in order to obtain a relatively high production yield.

    Russo, Thomas A; Johnson, James R

    2003-04-01

    Escherichia coli is probably the best-known bacterial species and one of the most frequently isolated organisms from clinical specimens. Despite this, underappreciation and misunderstandings exist among medical professionals and the lay public alike regarding E. coli as an extraintestinal pathogen. Underappreciated features include (i) the wide variety of extraintestinal infections E. coli can cause, (ii) the high incidence and associated morbidity, mortality, and costs of these diverse clinical syndromes, (iii) the pathogenic potential of different groups of E. coli strains for causing intestinal versus extraintestinal disease, and (iv) increasing antimicrobial resistance. In this era in which health news often sensationalizes uncommon infection syndromes or pathogens, the strains of E. coli that cause extraintestinal infection are an increasingly important endemic problem and underappreciated "killers". Billions of health care dollars, millions of work days, and hundreds of thousands of lives are lost each year to extraintestinal infections due to E. coli. New treatments and prevention measures will be needed for improved outcomes and a diminished disease burden.

    Performance assessment of geological disposal systems for high-level radioactive waste requires a consideration of long-term systems behaviour. It is possible that the alteration of swelling clay present in bentonite buffers might have an impact on buffer functions. In the present study, iron (as a candidate overpack material)-bentonite (I-B) interactions were evaluated as the main buffer alteration scenario. Existing knowledge on alteration of bentonite during I-B interactions was first reviewed, then the evaluation methodology was developed considering modeling techniques previously used overseas. A conceptual model for smectite alteration during I-B interactions was produced. The following reactions and processes were selected: 1) release of Fe 2+ due to overpack corrosion; 2) diffusion of Fe 2+ in compacted bentonite; 3) sorption of Fe 2+ on smectite edge and ion exchange in interlayers; 4) dissolution of primary phases and formation of alteration products. Sensitivity analyses were performed to identify the most important factors for the alteration of bentonite by I-B interactions. (author)

    In assessing the safety of engineering systems in the context of quantitative risk analysis one of the most important consequence types concerns the loss of life due to accidents and disasters. In this paper, a general approach for loss of life estimation is proposed which includes three elements: (1) the assessment of physical effects associated with the event; (2) determination of the number of exposed persons (taking into account warning and evacuation); and (3) determination of mortality amongst the population exposed. The typical characteristics of and modelling approaches for these three elements are discussed. This paper focuses on 'small probability-large consequences' events within the engineering domain. It is demonstrated how the proposed approach can be applied to various case studies, such as tunnel fires, earthquakes and flood events.

    Full Text Available Information technology (IT plays a vital role on developing different markets. In this paper, we study the impact of IT on developing businesses located mainly on free zones or in the borders of countries using analytical hierarchy process. The proposed study of this paper gathered the relative importance of five important factors influencing IT implementation. There are 12 experts and we use pairwise comparison to gather their insight and using Expert Choice we implement AHP for ranking the factors. The results indicate that management is the most important factor, followed by cultural and social items. The other factors including technical, investment and organization items are in lower degree of importance.

  8. Theoretical Analysis of Thermal Transport in Graphene Supported on Hexagonal Boron Nitride: The Importance of Strong Adhesion Due to π -Bond Polarization

    Science.gov (United States)

    Pak, Alexander J.; Hwang, Gyeong S.

    2016-09-01

    One important attribute of graphene that makes it attractive for high-performance electronics is its inherently large thermal conductivity (κ ) for the purposes of thermal management. Using a combined density-functional theory and classical molecular-dynamics approach, we predict that the κ of graphene supported on hexagonal boron nitride (h -BN) can be as large as 90% of the κ of suspended graphene, in contrast to the significant suppression of κ (more than 70% reduction) on amorphous silica. Interestingly, we find that this enhanced thermal transport is largely attributed to increased lifetimes of the in-plane acoustic phonon modes, which is a notable contrast from the dominant contribution of out-of-plane acoustic modes in suspended graphene. This behavior is possible due to the charge polarization throughout graphene that induces strong interlayer adhesion between graphene and h -BN. These findings highlight the potential benefit of layered dielectric substrates such as h -BN for graphene-based thermal management, in addition to their electronic advantages. Furthermore, our study brings attention to the importance of understanding the interlayer interactions of graphene with layered dielectric materials which may offer an alternative technological platform for substrates in electronics.

  9. IMPORTANCE OF CONTEXTUAL DATA IN PRODUCING HEALTH TECHNOLOGY ASSESSMENT RECOMMENDATIONS: A CASE STUDY.

    Poder, Thomas G; Bellemare, Christian A

    2018-01-01

    Contextual data and local expertise are important sources of data that cannot be ignored in hospital-based health technology assessment (HTA) processes. Despite a lack of or unconvincing evidence in the scientific literature, technology can be recommended in a given context. We illustrate this using a case study regarding biplane angiography for vascular neurointervention. A systematic literature review was conducted, along with an analysis of the context in our setting. The outcomes of interest were radiation doses, clinical complications, procedure times, purchase cost, impact on teaching program, the confidence of clinicians in the technology, quality of care, accessibility, and the volume of activity. A committee comprising managers, clinical experts, physicians, physicists and HTA experts was created to produce a recommendation regarding biplane technology acquisition to replace a monoplane device. The systematic literature review yielded nine eligible articles for analysis. Despite a very low level of evidence in the literature, the biplane system appears to reduce ionizing radiation and medical complications, as well as shorten procedure time. Contextual data indicated that the biplane system could improve operator confidence, which could translate into reduced risk, particularly for complex procedures. In addition, the biplane system can support our institution in its advanced procedures teaching program. Given the advantages provided by the biplane technology in our setting, the committee has recommended its acquisition. Contextual data were of utmost importance in this recommendation. Moreover, this technology should be implemented alongside a responsibility to collect outcome data to optimize clinical protocol in the doses of ionizing delivered.

    The availability of suppositories in Hungary, especially in clinical pharmacy practice, is usually provided by extemporaneous preparations. Due to the known advantages of rectal drug administration, its benefits are frequently utilized in pediatrics. However, errors during the extemporaneous manufacturing process can lead to non-homogenous drug distribution within the dosage units. To determine the root cause of these errors and provide corrective actions, we studied suppository samples prepared with exactly known errors using both cerimetric titration and HPLC technique. Our results show that the most frequent technological error occurs when the pharmacist fails to use the correct displacement factor in the calculations which could lead to a 4.6% increase/decrease in the assay in individual dosage units. The second most important source of error can occur when the molding excess is calculated solely for the suppository base. This can further dilute the final suppository drug concentration causing the assay to be as low as 80%. As a conclusion we emphasize that the application of predetermined displacement factors in calculations for the formulation of suppositories is highly important, which enables the pharmacist to produce a final product containing exactly the determined dose of an active substance despite the different densities of the components.

    The Republic of Korea declared measles elimination in 2006. However, a measles outbreak occurred in 2013. This study aimed to identify the epidemiological characteristics of the sources of infection and the pattern of measles transmission in 2013 in South Korea. We utilized surveillance data, epidemiological data, immunization registry data, and genetic information. We describe the epidemiological characteristics of all measles case patients (sex, age distribution, vaccination status, sources of infection) as well as details of the outbreak (the pattern of transmission, duration, mean age of patients, and generation time). In 2013, a total of 107 measles cases were notified. Most patients were infants (43.0%) and unvaccinated individuals (60.7%). We identified 4 imported and 103 import-related cases. A total of 105 cases were related to four outbreaks that occurred in Gyeongnam, northern Gyeonggi, southern Gyeonggi, and Seoul. The predominant circulating genotype was B3 type, which was identified in the Gyeongnam, northern Gyeonggi, and southern Gyeonggi outbreaks. The B3 type had not been in circulation in South Korea in the previous 3 years; virologic evidence suggests that these outbreaks were import-related. Most measles cases in South Korea have been associated with imported measles virus. Although Korea has maintained a high level of herd immunity, clustering of susceptible people can cause such measles outbreaks.

    More affordable international travel, global trade and commerce, and the exporting of labor have all contributed to international population mobility. Furthermore, population migration leads to the incidence or recurrence of once-controlled diseases. Evidence shows that the popularity of travel can impact health through imported infections and illness. Imported cutaneous myiasis, a type of skin lesion, has attracted the attention of the current authors. This condition often occurs among travelers and it has been reported in several non-endemic countries. However, diagnosis of myiasis and identification of the larvae are difficult. Advances in molecular detection techniques could provide a new way to identify larvae. This study used sequencing of the 28S rRNA gene and morphology to identify the larva infesting the upper arm of a Chinese woman returning from Uganda. The larva was identified as Cordylobia anthropophaga (C. anthropophaga) and the sequences were submitted to GenBank (accession number: KM506761). As foreign interaction increases, imported health problems may become more common in China. Knowledge about various pathogens needs to be increased and molecular methods need to be used to accurately identify those pathogens.

    2015-01-01

    The great potential of lipases is known since 1930 when the work of J. B. S. Haldane was published. After eighty-five years of studies and developments, are lipases still important biocatalysts? For answering this question the present work investigated the technological development of four important industrial sectors where lipases are applied: production of detergent formulations; organic synthesis, focusing on kinetic resolution, production of biodiesel, and production of food and feed products. The analysis was made based on research publications and patent applications, working as scientific and technological indicators, respectively. Their evolution, interaction, the major players of each sector and the main subject matters disclosed in patent documents were discussed. Applying the concept of technology life cycle, S-curves were built by plotting cumulative patent data over time to monitor the attractiveness of each technology for investment. The results lead to a conclusion that the use of lipases as biocatalysts is still a relevant topic for the industrial sector, but developments are still needed for lipase biocatalysis to reach its full potential, which are expected to be achieved within the third, and present, wave of biocatalysis.

    This presentation discussed the impacts of imports, government policy and technology on future natural gas supply. Specifically, it discussed projections of natural gas supply and demand; the potential impact of imports on United States natural gas supply; the potential impacts of government policy on natural gas supply and demand; and the impact of technological innovations on natural gas supply such as coalbed methane and methane hydrate. Specific government policies that were examined included the American Recovery and Reinvestment Act of 2009; the American Clean Energy and Security Act of 2009; and the Clean Energy Jobs and American Power Act of 2009. It was concluded that the United States demand for natural gas will expand and that the impact of pending clean energy legislation is unclear. In addition, each potential future resource will face constraints and new resources may come on line in the next 20 years. figs.

    Though most childhood lead exposure in the USA results from ingestion of lead-based paint dust, non-paint sources are increasingly implicated. We present interdisciplinary findings from and policy implications of a case of elevated blood lead (13–18 mcg/dL, reference level Malaysian folk diaper powder. Analyses showed the powder contains 62 % lead by weight (primarily lead oxide) and elevated antimony [1000 parts per million (ppm)], arsenic (55 ppm), bismuth (110 ppm), and thallium (31 ppm). These metals are highly bioaccessible in simulated gastric fluids, but only slightly bioaccessible in simulated lung fluids and simulated urine, suggesting that the primary lead exposure routes were ingestion via hand-mouth transmission and ingestion of inhaled dusts cleared from the respiratory tract. Four weeks after discontinuing use of the powder, the infant’s venous blood lead level was 8 mcg/dL. Unregulated, imported folk remedies can be a source of toxicant exposure. Additional research on import policy, product regulation, public health surveillance, and culturally sensitive risk communication is needed to develop efficacious risk reduction strategies in the USA. The more widespread use of contaminated folk remedies in the countries from which they originate is a substantial concern.

  1. Ducks change wintering patterns due to changing climate in the important wintering waters of the Odra River Estuary

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Some species of birds react to climate change by reducing the distance they travel during migration. The Odra River Estuary in the Baltic Sea is important for wintering waterfowl and is where we investigated how waterbirds respond to freezing surface waters. The most abundant birds here comprise two ecological groups: bottom-feeders and piscivores. Numbers of all bottom-feeders, but not piscivores, were negatively correlated with the presence of ice. With ongoing global warming, this area is increasing in importance for bottom-feeders and decreasing for piscivores. The maximum range of ice cover in the Baltic Sea has a weak and negative effect on both groups of birds. Five of the seven target species are bottom-feeders (Greater Scaup Aythya marila, Tufted Duck A. fuligula, Common Pochard A. ferina, Common Goldeneye Bucephala clangula and Eurasian Coot Fulica atra, and two are piscivores (Smew Mergellus albellus and Goosander Mergus merganser. Local changes at the level of particular species vary for different reasons. A local decline of the Common Pochard may simply be a consequence of its global decline. Climate change is responsible for some of the local changes in the study area, disproportionately favoring some duck species while being detrimental to others.

  2. Efficient technologies or user behaviour, which is the more important when reducing households' energy consumption?

    2013-08-15

    Much policy effort focuses on energy efficiency of technology, though not only efficiency but also user behaviour is an important factor influencing the amount of consumed energy. This paper explores to what extent energy efficiency of appliances and houses or user behaviour is the more important, both for understanding why some households consume much more energy than others, and when looking for relevant approaches to a future low-carbon society. The paper uses several sources to explore this question, most of them from a Danish context, including results from the researcher's own projects and Danish national statistics. These Danish data are discussed together with international studies. Through the presentation of these different projects and examples, it is shown how user behaviour is at least as important as the efficiency of technology when explaining households' energy consumption in Denmark. In the conclusion, these results are discussed in a broader international perspective and it is concluded that more research in this field is necessary. In relation to energy policy, it is argued that it is not a question of technology efficiency or behaviour, as both have to be included in future policy if energy demand is actually to be reduced. Furthermore, it is also argued that not only individual behaviour is relevant, but also a broader perspective on collectively shared low-carbon practices has to be promoted.

  3. Organizational and technological insight as important factors for successful implementation of IT.

    1999-01-01

    Politicians and hospital management in Sweden and Denmark focus on IT and especially Electronic Patient Record, EPR as a tool for changes that will lead to better economy as well as better quality and service to the patients. These changes are not direct effects of the new medium for patient records but indirect effects due to the possibilities embedded in the new technology. To ensure that the implementation is successful, i.e. leads to changes in organization structure and workflow, we need tools to prepare clinicians and management. The focus of this paper is the individual insight in technology and organization and it proposes a model to assess and categorize the possibilities of individuals and groups to participate in and make an implementation process powerful.

We came to the conclusion that in an organisation the importance of intellectual and social capital, intangible capital assets and their continuous measurement has to be emphasised in order to increase the importance (awareness of KM.

  5. Effect of imports of uranium on the national security. Critical technologies

    International Nuclear Information System (INIS)

    1989-09-01

    The report gives results of an investigation to determine the effects of uranium imports on the national security. Uranium is essential to the operation of the Navy's nuclear-powered fleet, for nuclear weapon capability and for civilian nuclear energy generation. US utilities imported 43.8 percent of their uranium requirements in 1986 and 51.1 percent in 1987. The report finds that the domestic industry's competitiveness has deteriorated in recent years, due to the easily accessible and richer deposits available elsewhere. The report concludes, however, that in a national security emergency, defense requirements could be met through stockpiles of finished nuclear materials set aside for military needs. Furthermore, civilian requirements could be met through US production, reliable imports, inventories, and tails reprocessing. The report, therefore, finds that uranium is not being imported in such quantities or under such circumstances as to represent a threat to the national security

    High-content screening (HCS) was introduced about twenty years ago as a promising analytical approach to facilitate some critical aspects of drug discovery. Its application has spread progressively within the pharmaceutical industry and academia to the point that it today represents a fundamental tool in supporting drug discovery and development. Here, the authors review some of significant progress in the HCS field in terms of biological models and assay readouts. They highlight the importance of high-content screening in drug discovery, as testified by its numerous applications in a variety of therapeutic areas: oncology, infective diseases, cardiovascular and neurodegenerative diseases. They also dissect the role of HCS technology in different phases of the drug discovery pipeline: target identification, primary compound screening, secondary assays, mechanism of action studies and in vitro toxicology. Recent advances in cellular assay technologies, such as the introduction of three-dimensional (3D) cultures, induced pluripotent stem cells (iPSCs) and genome editing technologies (e.g., CRISPR/Cas9), have tremendously expanded the potential of high-content assays to contribute to the drug discovery process. Increasingly predictive cellular models and readouts, together with the development of more sophisticated and affordable HCS readers, will further consolidate the role of HCS technology in drug discovery.

    Full Text Available The rapid scientific and technological development imposes numerous changes in all spheres of life and work. In such circumstances, a computer has become a part of all aspects of life: economy, education, free time, family. Since children in contemporary society increasingly acquire knowledge before the school age, the question is how to prepare them for the world in which we live, bearing in mind how significantly different it is from the world in which the previous generations grew up. The research was aimed at examining the attitudes of preschool teachers about the importance of computers in the realization of educational activities in preschool institutions. The study included 54 teachers from Kosovo and Metohija: Kosovska Mitrovica, Donja Gušterica and Ropotovo. The research results indicate that digital technology is a very important and a useful didactic tool in the realization of educational activities in preschool institutions and that preschool teachers have the required competence to implement the technology. However, they are not satisfied with the quality of their ICT education and training during their studies; they also feel that their institutions do not provide adequate working conditions for the use of computers in the realization of educational tasks.

    Full Text Available Eacters of coccus or rods Gram-positive, catalase negative, non-sporulating, which produce lactic acid as the major end product during the fermentation of carbohydrates. When applied on food, provides beneficial effects to consumers through its functional and technological properties. With this the present review article, explore the potential application of lactic acid bacteria in food. The following genera are considered the principal lactic acid bacteria: Aerococcus, Carnobacterium, Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Oenococcus, Pediococcus, Streptococcus, Tetragenococcus, Vagococcus and Weissella. These cultures have been used as starter or adjunct cultures for the fermentation of foods and beverages due to their contributions to the sensorial characteristics of these products and by microbiological stability. Their probiotic properties have also been investigated. More recent studies by indigenous cultures have received increased attention in light of the search for isolated cultures of a given raw material and a certain region. These microorganisms are being investigated for its functional and technological potential that may be applied in product development with its own characteristics and designation of origin. Those properties will be discussed in the present review in order to highlight the performance of these bacteria and the high degree of control over the fermentation process and standardization of the final product. The use of autochthonous cultures will be considered due the increase of studies of new cultures of lactic acid bacteria isolated of milk and meat of distinct products.

  10. Less-studied TCE: are their environmental concentrations increasing due to their use in new technologies?

    Filella, M; Rodríguez-Murillo, J C

    2017-09-01

    The possible environmental impact of the recent increase in use of a group of technology-critical elements (Nb, Ta, Ga, In, Ge and Te) is analysed by reviewing published concentration profiles in environmental archives (ice cores, ombrotrophic peat bogs, freshwater sediments and moss surveys) and evaluating temporal trends in surface waters. No increase has so far been recorded. The low potential direct emissions of these elements, resulting from their absolute low production levels, make it unlikely that the increasing use of these elements in modern technology has any noticeable effect on their environmental concentrations on a global scale. This holds particularly true for those of these elements that are probably emitted in relatively high amounts from other human activities (i.e., coal combustion and non-ferrous smelting), such as In, the most studied element of the group.

    The sensitivity of MOS memory components to errors induced by alpha particles is expected to increase with integration level. The soft error rate of a 65-kbit VMOS memory has been compared experimentally with that of three field-proven 16-kbit designs. The technological and design advantages of the VMOS RAM ensure an error rate which is lower than those of the 16-kbit memories. Calculation of the error probability for the 65-kbit RAM and comparison with the measurements show that for large duty cycles single particle hits lead to sensing errors and for small duty cycles cell errors caused by multiple hits predominate.

    1976-01-01

    The tritium technology requirements created by the controlled thermonuclear research program to develop a demonstration fusion power reactor by the year 2000 are reviewed. It is found that the majority of the technological advances which are needed to ensure adequate tritium containment in a tritium breeding power reactor need to be demonstrated on a pilot scale by approximately 1983, so that they may be incorporated into EPR-II, the second of two planned experimental power reactors. The most important advances include development of containment materials with permeabilities to tritium well below measured values for stainless steel; large scale, low inventory deuterium-tritium separation systems; and improved monitoring and assay systems. There are less critical requirements for information about the effects of tritium and helium on the mechanical properties of materials, the effects of tritium on biological systems, and data on physical and chemical properties of tritium. Substantial progress needs to be made on these problems early enough to permit possible solutions to be tested on EPR-I. In addition, major improvements in tritium handling equipment are required for EPR-I. Those technological problems for which solutions have not yet been demonstrated by EPR-II must be solved by 1989 if they are to be assured successful application in the demonstration reactor

    Full text: Many precious elements (Au, Re, Pt, Pd, Ag, Cu, Ni, Co, Mo) in ores mainly exist in the form of sulfide minerals and the flotation method is often used for processing of such kind of ores. To enhance the efficiency of the process it is very important to carry out the operative control of the elements of interest at various stages of ore processing. In this work the results of studies for developing methods for control of technologically important elements at processing and enrichment sulfide ores, which content the gold, copper, nickel, molybdenum in the ore-processing plants of Uzbekistan. The design of transportable experimental PGAA device on the basis of low-power radionuclide neutron source ( 252 Cf) with neutrons of 2x10 7 neutr/sec allowing to determine element content of the above named ores and their processing products is offered. It is shown that the use of the thermal neutron capture gamma-ray spectrometry in real samples and technological products allows prompt determination of such elements as S, Cu, Ti and others, which are important for flotation of sulfide ores. Efficiency control of the flotation processing of sulfide ores is based on quick determination of the content of sulfur and some other important elements at different stages of the process. It was found that to determine elements the following gamma lines are the most suitable - 840.3 keV for sulfur, 609 keV and 7307 keV for copper and 1381.5 keV, 1498.3 keV and 1585.3 keV for titanium. Based on the measurements of original ores, concentrates of various stages of flotation and flotation slime the possibility for prompt determination of S, Cu and Ti content and thus to get necessary information on the efficiency of the flotation process was shown.

Fetus of 26-weeks' gestation with antenatally diagnosed large abdominal tumor. ART with transfer of cryopreserved embryo. Postmortem examination. Examination revealed a congenital mesoblastic nephroma, mixed classic and cellular type, with marked intratumoral hemorrhage and associated hydrops. The marked fetal erythroblastosis was suggestive of fetal response to pronounced anemia. Intrauterine demise is attributed to fetal intratumoral hemorrhage and early nonimmune hydrops secondary to a large congenital mesoblastic nephroma. This is the third reported case of congenital mesoblastic nephroma in an ART conception. Whether the association between mesoblastic nephroma and ART is coincidental or causative remains to be determined. Copyright © 2011 American Society for Reproductive Medicine.

  18. Characterization of ultrathin insulators in CMOS technology: Wearout and failure mechanisms due to processing and operation

    Science.gov (United States)

    Okandan, Murat

    In the CMOS technology the gate dielectric is the most critical layer, as its condition directly dictates the ultimate performance of the devices. In this thesis, the wear-out and failure mechanisms in ultra-thin (around 50A and lower) oxides are investigated. A new degradation phenomenon, quasi-breakdown (or soft-breakdown), and the annealing and stressing behavior of devices after quasi-breakdown are considered in detail. Devices that are in quasi-breakdown continue to operate as switches, but the gate leakage current is two orders of magnitude higher than the leakage in healthy devices and the stressing/annealing behavior of the devices are completely altered. This phenomenon is of utmost interest, since the reduction in SiO2 dielectric thickness has reached its physical limits, and the quasi-breakdown behavior is seen to dominate as a failure mode in this regime. The quasi-breakdown condition can be brought on by stresses during operation or processing. To further study this evolution through stresses and anneals, cyclic current-voltage (I-V) measurement has been further developed and utilized in this thesis. Cyclic IV is a simple and fast, two terminal measurement technique that looks at the transient current flowing in an MOS system during voltage sweeps from accumulation to inversion and back. During these sweeps, carrier trapping/detrapping, generation and recombination are observed. An experimental setup using a fast electrometer and analog to digital conversion (A/D) card and the software for control of the setup and data analysis were also developed to gain further insight into the detailed physics involved. Overall, the crucial aspects of wear-out and quasi-breakdown of ultrathin dielectrics, along with the methods for analyzing this evolution are presented in this thesis.

    Full Text Available For many years, there has been confusion about the role that nutrition plays in inflammatory bowel diseases (IBD. It is apparent that good dietary advice for one individual may prove inappropriate for another. As with many diseases, genome-wide association studies across large collaborative groups have been important in revealing the role of genetics in IBD, with more than 200 genes associated with susceptibility to the disease. These associations provide clues to explain the differences in nutrient requirements among individuals. In addition to genes directly involved in the control of inflammation, a number of the associated genes play roles in modulating the gut microbiota. Cell line models enable the generation of hypotheses as to how various bioactive dietary components might be especially beneficial for certain genetic groups. Animal models are necessary to mimic aspects of the complex aetiology of IBD, and provide an important link between tissue culture studies and human trials. Once we are sufficiently confident of our hypotheses, we can then take modified diets to an IBD population that is stratified according to genotype. Studies in IBD patients fed a Mediterranean-style diet have been important in validating our hypotheses and as a proof-of-principle for the application of these sensitive omics technologies to aiding in the control of IBD symptoms.

    Objective: To retrospectively evaluate the digital subtraction angiography (DSA) bolus chase technology in diagnosing the vascular disorders of lower extremities due to diabetes mellitus. Methods: From January 2004 to March 2010, DSA was performed in forty-five diabetes patients with suspicious vascular diseases of lower extremities. Among them, 24 cases (31 lower limbs)were examined with DSA bolus chase technology and the remaining 21 cases (21 lower limbs)were examined with traditional segmentational technique. The contrast dosage used in angiography, the total exposure time, the examination time and the imaging value for making diagnosis were analyzed and compared between two techniques. Results: For DSA bolus chase technology group, the contrast dosage used in angiography, the total exposure time and the examination time were 25.26 ml, 13.23 s and 37.26 min, respectively,with an average exposure of 101.65 pictures. For traditional segmentational technique group, the contrast dosage used in angiography, the total exposure time and the examination time were 130.00 ml, 52.38 s and 50.48 min, respectively, with an average exposure of 118.33 pictures. The percentage of high quality images in bolus chase technology group and in traditional segmentational technique group were 90.3% and 90.5%, respectively. All the images could meet the requirements for making a reliable diagnosis. Conclusion: Digital subtraction angiography by using bolus-chase technology can well demonstrate the vascular pathology of lower extremities caused by diabetes mellitus, obtain sufficient imaging information necessary for making a reliable diagnosis. DSA bolus chase technology is superior to traditional segmentational technique in shortening procedure time, reducing contrast medium dosage and decreasing radiation dose. (authors)

    Full Text Available In order to investigate the attitude of elite coaches of the team and individual sports towards the role and importance of information technology in sport, 132 coaches were chosen as a sample and answered to the questionnaire of the role of information technology in sport organised by Liebermann and Katz that consisted of 3 different sections: A General attitude of the coaches towards computer and technology; B The importance of science and technology in achieving coaching experience; C Understanding science and technology in sport. Descriptive and inferential statistics (CFA and independent t - test were used in order to analyse the data. The findings demonstrated that elite coaches selected two aims as their chief ones: 1 - Winning medals in competitions; 2- Having a good relationship with the athletes. There was not any significant relationship between the attitudes of the men and women and the coaches of the individual and team sports on science and technology. It seems that elite coaches are aware on the general importance of sport sciences and have a positive attitude towards the use of sport technologies. But they do not practically transfer this positive attitude to competitive sport environments even when they use information technology for other purposes. Eventually it can be stated that the attitude of the coaches towards technology is very positive and consequently it is a must to find strategies in order to encourage them to use current technology and science practically.

    Full Text Available A problem of industrial fluxed agglomerates self-destruction in the process of cooling after sintering has been examined. It has been revealed that the main reason of strength degradation is polymorphism of dicalcium silicate Ca2SiO4 (or short designation С2S: β-Ca2SiO4 ® γ-Ca2SiO4. Ways for increasing the  agglomerate  strength by physical and crystal-chemical stabilization of the high temperature modification of C2S have been proposed and tested. Physical stabilization of C2S agglomerate is increased with its structure reinforcement due to thickening of walls between large pores that is achieved by increasing height of the sintered layer through improvement of its gas permeability. The task is addressed by substituting the previously used import sintering ore with the  polydisperse ore from the Yakovlevo field, which improves the charge  pelletizing by 3-4 times and helps to bring the  height of the sintered layer and the strength of the domestic agglomerate up to the international best practice standards, while eliminating a need to purchase import high-vacuum   exhausters. In practice crystal-chemical stabilization of C2S within iron-ore  agglomerate is ensured by adding an  opti- mal multicomponent additive in the form of the    waste product  generated in production  of alumina  from bauxites, i.e. the red mud, to the initial sinter charge. Thus mechanical strength of agglomerates and pellets is increased by 5-10 % and their hot strength improves by 20-40 %. The productivity of sintering machines and blast furnaces improves by 5-10 %. Specific coke consumption reduces by 2-2.5 %. In production of iron-ore pellets red mud is substituting the import  bentonite.

    Young adults with disabilities often use assistive technology (AT) to address personal needs, engage in communities and pursue educational and vocational goals. Little is known about their personal experiences and challenges of accessing and using AT for productivity-related activities. This study aimed to learn from young adults about their experiences and use of AT in supporting their productivity. Using a qualitative approach, 20 young adult AT users engaged in semi-structured interviews and a photovoice process. Data were analysed inductively. Three primary themes were identified: I Have to Figure it out Myself, With the Right AT, and Relational Aspects of AT Use. Although participants were experienced AT users, they were often left alone to figure out their emerging needs. They relied on AT to participate in productivity pursuits however stigma around AT use in unsupportive work environments were new concerns. Young adults with disabilities draw on their experiences of AT use but may need to develop advocacy skills to ensure their needs are met in productivity-related environments. Employers and supervisors should recognize AT as essential to young adult's engagement with productivity-related activities and have an important role in developing inclusive work environments.

    Care coordination and transitional care services are strategically important for achieving the priorities of better care, better health, and reduced costs embodied in the National Strategy for Quality Improvement in Health Care (National Quality Strategy [NQS]). Some of the most vulnerable times in a person’s care occur with changes in condition as well as movement within and between settings of care. The American Academy of Nursing (AAN) believes it is essential to facilitate the coordination of care and transitions by using health information technology (HIT) to collect, share, and analyze data that communicate patient-centered information among patients, families, and care providers across communities. HIT makes information accessible, actionable, timely, customizable, and portable. Rapid access to information also creates efficiencies in care by eliminating redundancies and illuminating health history and prior care. The adoption of electronic health records (EHRs) and information systems can enable care coordination to be more effective but only when a number of essential elements are addressed to reflect the team-based nature of care coordination as well as a focus on the individual’s needs and preferences. To that end, the AAN offers a set of recommendations to guide the development of the infrastructure, standards, content, and measures for electronically enabled care coordination and transitions in care as well as research needed to build the evidence base to assess outcomes of the associated interventions.

    2007-01-01

    This paper explores the direct effect of ownership and technology imports under the fiamework of neoclassical economic theory.The econometric analysis is based on panel data from a random sample of large and mediumenterprises in Shanghai,during the period of 1998 to 2003.The results show that Sino-foreign joint ventures,Sino-foralgn cooperative enterprises and foreignfunded enterprises (SANZI) enjoy higher labor productivity and total factor productlvity (TFP) than domestic enterprises.Intra-firm diffusion of non-codified technology,proxied by ovwnership,is the main source of their better performance,whereas internally transferred codified technology makes little contribution to TFP.For state-owned enterprises,codified technology imports have significantly raised both labor productivity and TFP,but such positive effect is significantly dependent on the S&T human resource.In contrast,no evidence supports that introduction of foreign technology has enhanced the productivity in domestic nonstate-owned enterprises.The empirical results indicate that SANZI do not have a distinct advantage in their codified technology.In addition,inadequate investment in assimilation process and research and development together with inefficient management of science and technology activities,may impede the use of imported technology.

  15. ICT security- aspects important for nuclear facilities; Information and Communication Technologies

    2005-09-15

    Rapid application growth of complex Information and Communication Technologies (ICT) in every society and state infrastructure as well as industry has revealed vulnerabilities that eventually have given rise to serious security breaches. These vulnerabilities together with the course of the breaches from cause to consequence are gradually about to convince the field experts that ensuring the security of ICT-driven systems is no longer possible by only relying on the fundaments of computer science, IT, or telecommunications. Appropriating knowledge from other disciplines is not only beneficial, but indeed very necessary. At the same time, it is a common observation today that ICT-driven systems are used everywhere, from the nuclear, aviation, commerce and healthcare domains to camera-equipped web-enabled cellular phones. The increasing interdisciplinary and inter-sectoral aspects of ICT security worldwide have been providing updated and useful information to the nuclear domain, as one of the emerging users of ICT-driven systems. Nevertheless, such aspects have also contributed to new and complicated challenges, as ICT security for the nuclear domain is in a much more delicate manner than for any other domains related to the concept of safety, at least from the public standpoint. This report addresses some important aspects of ICT security that need to be considered at nuclear facilities. It deals with ICT security and the relationship between security and safety from a rather different perspective than usually observed and applied. The report especially highlights the influence on the security of ICT-driven systems by all other dependability factors, and on that basis suggests a framework for ICT security profiling, where several security profiles are assumed to be valid and used in parallel for each ICT-driven system, sub-system or unit at nuclear facilities. The report also covers a related research topic of the Halden Project with focus on cyber threats and

    Full Text Available The authors’ understanding of neuro-programming is the result of the impact on the human brain of information and communication technology (including educational one, through which in the human brain the programs of manifestation in the ontogenesis of internal creative potentials are written. This article summarizes the history of the formation of key neuro-programming technologies of the human brain as well as proves that the changes in the society’s worldview are caused by the possibilities and quality of neuro-programming technologies that society uses. Having influence over worldview stereotypes and behaviour set by the society, neuro-programming technologies essentially ensure the national security of any state and the peaceful coexistence of states in the regions and on the planet as a whole. Using historical and philosophical methods, methods of conceptualization, systematization, modeling, etc., the authors have come to the conclusion that the modern world lies in a confrontation of security strategies, in which neuro-programming technologies play a key role.

  19. Epidemiology of Blood Stream Infection due to Candida Species in a Tertiary Care Hospital in Japan over 12 Years: Importance of Peripheral Line-Associated Candidemia.

    Full Text Available Candidemia is an important cause of mortality in healthcare settings. Peripheral lines are a source of candidemia, yet few studies have reported on the clinico-epidemiological features of candidemia due to peripheral-line associated blood stream infection (PLABSI.We conducted a single-centre retrospective cohort study of all patients with candidemia between 2002 and 2013. PLABSI was defined as the presence of at least one of the following: the presence of phlebitis or the resolution of clinical symptoms after peripheral-line withdrawal, with careful exclusion of an alternative explanation for bacteraemia. We described the epidemiology of candidemia and assessed predictive factors of PLABSI due to Candida spp., peripheral line-associated candidemia (PLAC, compared with non-PLAC.A total of 301 episodes of candidemia, including 37 of PLAC, were diagnosed during the study period. Central-line associated blood stream infection, intra-abdominal infection, and infection of unknown source accounted for the remaining 233, 14, and 17 cases, respectively. The overall incidence rate of candidemia was 0.11/1000 patient-days. In multivariate analysis, cephalosporin exposure (odds ratio [OR] = 2.22, 95% CI 1.04-4.77, polymicrobial bacteraemia/fungaemia (OR = 2.87, 95% CI 1.02-8.10, and ID specialist consultation (OR = 2.40, 95% CI 1.13-5.13 were identified as independent predictors of PLAC. Although non-PLAC had a higher mortality, the length of hospital stay after candidemia was similar between the two groups and candidemia duration was longer in the PLAC group.PLACs are an important cause of candidemia in hospitalized patients. Appropriate identification and management of PLAC are crucial.

    1995-01-01

    The issues of technology and armament transfers are increasingly at the forefront of problems of international security and disarmament. Three major reasons could explain this. First, the disarmament process has been very successful in the last few years, especially in the field of nuclear, as well chemical and conventional, weapons. Second the disarmament effort underway concerns primarily the old partners of the East-West confrontation. Last, the general context, characterized by the opening and widening of exchanges, the increasingly open and transparent circulation of techniques and material, and the globalization of economic relations, must be taken into account. This report, prepared by UNIDIR comprises the following subjects: General trends in defense related transfers; Political/military factors associated with the diffusion of advanced technology; economic and technological consideration; and facilitation of economic growth/maximization of regional security and stability

  1. Minimum Viable Product and the Importance of Experimentation in Technology Startups

    Dobrila Rancic Moogk

    2012-03-01

    Full Text Available Entrepreneurs are often faced with limited resources in their quest to commercialize new technology. This article presents the model of a lean startup, which can be applied to an organization regardless of its size or environment. It also emphasizes the conditions of extreme uncertainty under which the commercialization of new technology is carried out. The lean startup philosophy advocates efficient use of resources by introducing a minimum viable product to the market as soon as possible in order to test its value and the entrepreneur’s growth projections. This testing is done by running experiments that examine the metrics relevant to three distinct types of the growth. These experiments bring about accelerated learning to help reduce the uncertainty that accompanies commercialization projects, thereby bringing the resulting new technology to market faster.

  3. Markets for Technology and the Importance of Firm-Specific Search for Innovation Performance

    DEFF Research Database (Denmark)

    Sofka, Wolfgang; Grimpe, Christoph

    Firms rely increasingly on external knowledge, e.g. from universities, to improve their innovation performance. Existing research models the acquisition of knowledge either as a firm-specific search or a purchase on markets for technology. The former implies that a firm chooses and develops...... relationships with knowledge sources while the latter suggests a transaction governed by markets. We argue that both mechanisms increase a firm’s innovation performance but that they are interrelated. While on the firm level firm-specific search and acquisitions on markets for technology complement each other......, the costs of firm-specific search are only justified in underdeveloped markets. Otherwise, market transactions provide higher efficiency and flexibility. This negative cross-level interaction effect is stronger the more knowledge in an industry is covered by markets for technology. We test and support...

  4. Health care technology--information technology/Part 4. Why will the Internet be important to clinicians?

    Science.gov (United States)

    Ruffin, M

    1996-10-01

    As the popularity of the Internet's World Wide Web exploded in 1994 and 1995, corporations began adopting the browser software called Mosaic (and its derivatives) for their networks. Why? That same software can be used to "surf" the Internet. Since Intranets are easier to maintain and less expensive, they are replacing the more expensive "groupware" applications based on client-server architectures that corporations installed over the past five years. These Intranets are based on widely-available technologies designed for the Internet, not proprietary software designed for a relatively few customers. Organizations with communication networks integrated with their transaction systems and electronic medical records will be more effective in managing health care resources--and more attractive to employers and insurers for managed care contracting.

  6. The importance of technological innovation in the logistics of ethanol exports

    Directory of Open Access Journals (Sweden)

    José Petraglia

    2011-07-01

    Full Text Available This paper analyzes the technological status of the bulk liquids logistical process at the port of Santos. The main objective is to identify problems encountered in port logistics for the export of ethanol and evaluate their respective technological innovation perspectives. Ethanol exports have increased given international environmental appeals. Within the complex and uncertain environments that contemporary corporations are experiencing, environmental issues have captured global attention. There is an awareness as to the relevance of reducing pollutant emissions to the atmosphere and one of the manners of so doing is by utilising ethanol as a source of propulsion energy fuelling automobile engines. Brazil is one of largest, high quality, ethanol producers in the world and a strong competitor to serve the global market given that the quality of the port logistic infrastructure poses significant impact on exports. Thus, this article proposes to further deepen the theory fundamentals alongside research conducted at companies of South-central Brazil´s sugar alcohol supply chain sector. The study´s analytical model is based on bibliographical research, monitoring and descriptive field surveys at companies within the segment. The article demonstrates that although the logistical process is evolving technologically, further investments in logistic infrastructure is required so as to obtain a sustainable competitive advantage and ensure the feasibility of exports of the Brazilian product.Key words: logistic process, technological innovation and ethanol.

    Ethiopia joined the Global Polio Eradication Initiative (GPEI) in 1996, and by the end of December 2001 circulation of indigenous Wild Polio Virus (WPV) had been interrupted. Nonetheless, the country experienced multiple importations during 2004-2008, and in 2013. We characterize the 2013 outbreak investigations and response activities, and document lessons learned. The data were pulled from different field investigation reports and from the national surveillance database for Acute Flaccid Paralysis (AFP). In 2013, a WPV1 outbreak was confirmed following importation in Dollo zone of the Somali region, which affected three Woredas (Warder, Geladi and Bokh). Between July 10, 2013, and January 5, 2014, there were 10 children paralyzed due to WPV1 infection. The majorities (7 of 10) were male and below 5 years of age, and 7 of 10 cases was not vaccinated, and 72% (92/129) of < 5 years of old children living in close proximity with WPV cases had zero doses of oral polio vaccine (OPV). The travel history of the cases showed that seven of the 10 cases had contact with someone who had traveled or had a travel history prior to the onset of paralysis. Underserved and inaccessibility of routine immunization service, suboptimal surveillance sensitivity, poor quality and inadequate supplemental immunization were the most crucial gaps identified during the outbreak investigations. Prior to the 2013 outbreak, Ethiopia experienced multiple imported polio outbreaks following the interruption of indigenous WPV in December 2001. The 2013 outbreak erupted due to massive population movement and was fueled by low population immunity as a result of low routine immunization and supplemental Immunization coverage and quality. In order to avert future outbreaks, it is critical that surveillance sensitivity be improved by establishing community-based surveillance systems and by assigning surveillance focal points at all level particularly in border areas. In addition, it is vital to set

  14. Energy loss of solar p modes due to the excitation of magnetic sausage tube waves: Importance of coupling the upper atmosphere

    International Nuclear Information System (INIS)

    Gascoyne, A.; Jain, R.; Hindman, B. W.

    2014-01-01

    We consider damping and absorption of solar p modes due to their energy loss to magnetic tube waves that can freely carry energy out of the acoustic cavity. The coupling of p modes and sausage tube waves is studied in a model atmosphere composed of a polytropic interior above which lies an isothermal upper atmosphere. The sausage tube waves, excited by p modes, propagate along a magnetic fibril which is assumed to be a vertically aligned, stratified, thin magnetic flux tube. The deficit of p-mode energy is quantified through the damping rate, Γ, and absorption coefficient, α. The variation of Γ and α as a function of frequency and the tube's plasma properties is studied in detail. Previous similar studies have considered only a subphotospheric layer, modeled as a polytrope that has been truncated at the photosphere. Such studies have found that the resulting energy loss by the p modes is very sensitive to the upper boundary condition, which, due to the lack of an upper atmosphere, have been imposed in a somewhat ad hoc manner. The model presented here avoids such problems by using an isothermal layer to model the overlying atmosphere (chromosphere, and, consequently, allows us to analyze the propagation of p-mode-driven sausage waves above the photosphere. In this paper, we restrict our attention to frequencies below the acoustic cut off frequency. We demonstrate the importance of coupling all waves (acoustic, magnetic) in the subsurface solar atmosphere with the overlying atmosphere in order to accurately model the interaction of solar f and p modes with sausage tube waves. In calculating the absorption and damping of p modes, we find that for low frequencies, below ≈3.5 mHz, the isothermal atmosphere, for the two-region model, behaves like a stress-free boundary condition applied at the interface (z = –z 0 ).

    2014-01-01

    Photovoltaic (PV) has the highest cost reduction potential among all renewable energy sources (RES). To overcome institutional barriers, developing the technology, and creating an initial market, policies are needed. Comparative case studies of Japan and German PV sector from 1990 to 2011 were developed. Japan dominated the PV industry during 1994–2004, PV market increased to 290 MW in 2005. After 2005 Japan's PV market decreased. German PV market increased from 44 MW in 2000 to 7.5 GW in 2011. The reason behind Japanese PV market decline was the unaligned energy policy and termination of incentives. This paper discusses about successful policy implementation and the impact of policy for the diffusion of PV technology. The analysis section of this paper shows how much the PV technology has been diffused during the period of 1990–2011 and finally what will make the transformation process successful. - Highlights: • We studied PV diffusion of Japan and German considering public energy policy, environmental policy and cost reduction. • This study determined that policy and incentives are responsible for cost reduction. • Japans concentration on nuclear energy more than renewables, made the PV diffusion slow. • Successful implementation of FIT helped Germany reduce PV electricity price more than grid electricity

    2013-02-01

    The protozoan Hepatozoon canis, which is transmitted via ingestion of infected ticks by canine hosts, is not endemic to mid-latitude regions in Europe. Its distribution is supposed to be linked to the occurrence of its primary tick vector Rhipicephalus sanguineus. A young male golden jackal (Canis aureus) found as road kill close to Vienna, Austria, was infected by this pathogen. Cloning and sequencing of the PCR product revealed 6 different haplotypes of H. canis. Based on the sequences, no clear relationship to the origin of infection could be traced. This is the first report of H. canis for Austria, and wild canines such as the currently found jackal may provide a source of natural spread of this parasite into non-endemic areas. This natural immigration of wild animals represents a way of pathogen introduction, which has to be considered in disease prevention in addition to human-made introduction due to animal import and export.

    1989-01-01

    The report contains the results of an investigation requested under Section 232 of the Trade Expansion Act to study the effect of oil imports on the domestic petroleum industry and on United States energy security. It reviews previous energy security assessments and resulting initiatives, assesses current US energy security, and studies emergency petroleum requirements. The report finds that there have been substantial improvements in US energy security since the last Section 232 Petroleum finding in 1979. However, declining domestic oil production, rising oil imports, and growing dependence on potentially insecure sources of supply raise concerns of vulnerability to a major supply disruption

    Development of novel hypersonic technologies necessarily requires the development of methods for analyzing a motion of hypervelocity vehicles. This paper could be considered as the initial stage in developing of complex computational model for studying flows around hypervelocity vehicles of arbitrary shape. Essential part of the model is a solution to three-dimensional transport equations for mass, momentum and energy for the medium in the state of both LTE (local thermodynamic equilibrium) and non-LTE. One of the primary requirements to the developed model is the realization on the modern heterogeneous computer systems including both CPU and GPU. The paper presents the first results on numerical simulation of hypersonic flow. The first problem considered is three-dimensional flow around curved body under angle of attack. The performance of heterogeneous 4-GPU computer system is tested. The second problem highlights the capabilities of the developed model to study heat and mass transfer problems. Namely, interior heat problem is considered which takes into account ablation of thermal protection system and variation of the surface shape of the vehicle. (paper)

  6. Important requirements for RF generators for Accelerator-Driven Transmutation Technologies (ADTT)

    1994-01-01

    All Accelerator-Driven Transmutation applications require very large amounts of RF Power. For example, one version of a Plutonium burning system requires an 800-MeV, 80-mA, proton accelerator running at 100% duty factor. This accelerator requires approximately 110-MW of continuous RF power if one assumes only 10% reserve power for control of the accelerator fields. In fact, to minimize beam spill, the RF controls may need as much as 15 to 20% of reserve power. In addition, unlike an electron accelerator in which the beam is relativistic, a failed RF station can disturb the synchronism of the beam, possibly shutting down the entire accelerator. These issues and more lead to a set of requirements for the RF generators which are stringent, and in some cases, conflicting. In this paper, we will describe the issues and requirements, and outline a plan for RF generator development to meet the needs of the Accelerator-Driven Transmutation Technologies. The key issues which will be discussed include: operating efficiency, operating linearity, effect on the input power grid, bandwidth, gain, reliability, operating voltage, and operating current

    Full Text Available Wheat is the second most cultivated crop on the world and is very important plant for feed not only mankind but also animals. Because of this is necessary to develop new varieties with better properties. Bread making quality of wheat grain is one of the most important paramaters for quality evaluation. Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE of wheat storage proteins and allelic specific polymerase chain reaction (AS-PCR are analysis suitable for identification, differentiation and characterization of bread wheat (Triticum aestivum L.. There were analysed 16 genotypes of new varieties of bread wheat in our work by SDS-PAGE and obtained results were verified by AS-PCR. Analysed genotypes of bread wheat genotypes were homogenous and single line with very good bread making quality. Our results confirmed hypothesis, that cultivated bread wheat genotypes are uniformed with high production and quality but there is a risk of sensitivity to environmental conditions. SDS-PAGE analyses of wheat grain proteins are fast and not very expensive technique, which provide us information of bread making quality of grains. However, there is possibility of environmental influence on protein synthesis and because of this is necessary to couple these analysis with analysis of DNA.

    New evaluation were performed for neutron- and proton-induced reactions for energies up to 250 400 MeV on C-12, N-14, O-16, Al-27, Si-28, Ca-40, Ar-40, Fe-54,58, Ni-64, Cu-63,65, Zr-90, Pb-208, Th-232, U-233,234,236, and Cm-243246. The evaluated results are then applied to the accelerator and space technology. A set of optical model parameters were optimized by searching a number of adjustable coefficients with the Simulated Annealing(SA) method for the spherical nuclei. A parameterization of the empirical formula was proposed to describe the proton-nucleus non-elastic cross sections of high-priority elements for space shielding purpose for proton energies from reaction threshold up to 400 MeV, which was then implemented into the fast scoping space shielding code CHARGE, based on the results of the optical model analysis utilizing up-to-date measurements. For proton energies up to 400 MeV covering most of the incident spectrum for trapped protons and solar energetic particle events, energy-angle spectra of secondary neutrons produced from the proton-induced neutron production reaction were prepared. The evaluated cross section set was applied to the thick target yield (TTY) and promp radiation benchmarks for the accelerator shielding.

  12. Research and deployment priorities for renewable technologies: Quantifying the importance of various renewable technologies for low cost, high renewable electricity systems in an Australian case study

    International Nuclear Information System (INIS)

    Riesz, Jenny; Elliston, Ben

    2016-01-01

    This study aims to identify research priorities to enable low cost, high renewable power systems. An evolutionary program optimises the mix of technologies in 100% renewable energy portfolios (RE) in the Australian National Electricity Market. Various technologies are reduced in availability to determine their relative importance for achieving low costs. The single most important factor is found to be the integration of large quantities of wind; therefore wind integration is identified as a research priority. In contrast, photovoltaics are found to “saturate” the system at less than 10% of total energy (in the absence of storage or demand management, installation of further photovoltaics does not contribute significant further value). This indicates that policies to promote utility-scale photovoltaics should be considered in partnership with complementary measures (such as demand side participation and storage). Biofuelled gas turbines are found to be important; a complete absence of bioenergy increases costs by AU$20–30/MWh, and even having only 0.1 TWh per year of bioenergy available reduces average costs by AU$3–4/MWh. Limits on the non-synchronous penetration (NSP) are found to be relatively expensive, suggesting a significant research priority around finding alternative approaches to providing synchronous services, such as inertia. Geothermal and concentrating solar thermal technologies do not appear essential as long as sufficient wind and peaking bioenergy is available. - Highlights: • Photovoltaics saturate early, suggesting they need complementary measures. • Biofuelled gas turbines or another peaking technology are important for low costs. • Limits on the non-synchronous penetration are relatively expensive.

    2015-01-01

    Alternative vehicles must appropriately interface with the electric grid and renewable generation to contribute to decarbonization. This study investigates the impact of infrastructure configurations and management strategies on the vehicle–grid interface and vehicle greenhouse gas reduction potential with regard to California's Executive Order S-21-09 goal. Considered are battery electric vehicles, gasoline-fueled plug-in hybrid electric vehicles, hydrogen-fueled fuel cell vehicles, and plug-in hybrid fuel cell vehicles. Temporally resolved models of the electric grid, electric vehicle charging, hydrogen infrastructure, and vehicle powertrain simulations are integrated. For plug-in vehicles, consumer travel patterns can limit the greenhouse gas reductions without smart charging or energy storage. For fuel cell vehicles, the fuel production mix must be optimized for minimal greenhouse gas emissions. The plug-in hybrid fuel cell vehicle has the largest potential for emissions reduction due to smaller battery and fuel cells keeping efficiencies higher and meeting 86% of miles on electric travel keeping the hydrogen demand low. Energy storage is required to meet Executive Order S-21-09 goals in all cases. Meeting the goal requires renewable capacities of 205 GW for plug-in hybrid fuel cell vehicles and battery electric vehicle 100s, 255 GW for battery electric vehicle 200s, and 325 GW for fuel cell vehicles. - Highlights: • Consumer travel patterns limit greenhouse gas reductions with immediate charging. • Smart charging or energy storage are required for large greenhouse gas reductions. • Fuel cells as a plug-in vehicle range extender provided the most greenhouse gas reductions. • Energy storage is required to meet greenhouse gas goals regardless of vehicle type. • Smart charging reduces the required energy storage size for a given greenhouse gas goal

    2016-01-01

    Highlights: • The Calcium Looping (CaL) technology is a potentially low cost and highly efficient postcombustion CO_2 capture technology. • Energy integration and sorbent behavior play a relevant role on the process. • The industrial competitiveness of the process depends critically on the minimization of energy penalties. • It may be used in precombustion capture systems and other industrial processes such as cement production. • Sorbent deactivation must be assessed under realistic conditions involving high CO_2 concentration in the calciner. - Abstract: The Calcium Looping (CaL) technology, based on the multicyclic carbonation/calcination of CaO in gas–solid fluidized bed reactors at high temperature, has emerged in the last years as a potentially low cost technology for CO_2 capture. In this manuscript a critical review is made on the important roles of energy integration and sorbent behavior in the process efficiency. Firstly, the strategies proposed to reduce the energy demand by internal integration are discussed as well as process modifications aimed at optimizing the overall efficiency by means of external integration. The most important benefit of the high temperature CaL cycles is the possibility of using high temperature streams that could reduce significantly the energy penalty associated to CO_2 capture. The application of the CaL technology in precombustion capture systems and energy integration, and the coupling of the CaL technology with other industrial processes are also described. In particular, the CaL technology has a significant potential to be a feasible CO_2 capture system for cement plants. A precise knowledge of the multicyclic CO_2 capture behavior of the sorbent at the CaL conditions to be expected in practice is of great relevance in order to predict a realistic capture efficiency and energy penalty from process simulations. The second part of this manuscript will be devoted to this issue. Particular emphasis is put on the

  16. Steatite and schist as contenders for the Global Heritage Stone Resource due to their importance in Brazil's natural stone built heritage

    Science.gov (United States)

    Gilberto Costa, Antônio

    2013-04-01

    In Brazil, European natural stones, such as marble and limestone, were used as building material at historically important buildings and monuments, mainly in coastal cities, as well as in contemporary urban centers. However, in the country's central region, these Italian and Portuguese marbles and limestones were scarcely used. Instead, they were substituted for soapstone and several types of schist. As of 1755, the former was employed because of the ease with which it can be worked, essentially in the sculptural art and in the production of ornamental elements. Characterized by the presence of talc, steatite can feature other minerals such as serpentine, chlorite, carbonate, amphiboles, oxides like hematite and magnetite, and sulfites like pyrite, all in broadly variable amounts, which can result in modification of its technological properties (Volumetric Weight, Porosity, Water Absorption, Uniaxial Compression, Abrasion Resistance, Thermal Expansion etc.). In such rocks, talc content will be a decisive factor in their coloration. The higher its talc content is the clearer and softer the stone type will be, which ends up being known as talc stone. In such cases, the rock can display different hues of green, blue and gray. When compared to other rocks, texture patterns containing talc crystals, chlorite and carbonate contribute to low absorption and porosity for steatites. Schists were equally used at historical buildings in the Brazilian inland, especially in constructions in Minas Gerais towns, both in the production of structural elements such as bases, corners, pillars and foundations and in the creation of ornaments. Featuring different compositions, such rocks - which almost always occur interlayered with other ones such as quartzite - display coloration ranging from hues of gray to green to blue. They can be quartz-sericite-albite-chlorite schists featuring great or no amounts of carbonate, magnetite, epidote and tourmaline, sometimes with garnet, such as in

    Paul, Sujata

    In the course of my PhD I have worked on a broad range of problems using simulations from first principles: from catalysis and chemical reactions at surfaces and on nanostructures, characterization of carbon-based systems and devices, and surface and interface physics. My research activities focused on the application of ab-initio electronic structure techniques to the theoretical study of important aspects of the physics and chemistry of materials for energy and environmental applications and nano-electronic devices. A common theme of my research is the computational study of chemical reactions of environmentally important molecules (CO, CO2) using high performance simulations. In particular, my principal aim was to design novel nano-structured functional catalytic surfaces and interfaces for environmentally relevant remediation and recycling reactions, with particular attention to the management of carbon dioxide. We have studied the carbon-mediated partial sequestration and selective oxidation of carbon monoxide (CO), both in the presence and absence of hydrogen, on graphitic edges. Using first-principles calculations we have studied several reactions of CO with carbon nanostructures, where the active sites can be regenerated by the deposition of carbon decomposed from the reactant (CO) to make the reactions self-sustained. Using statistical mechanics, we have also studied the conditions under which the conversion of CO to graphene and carbon dioxide is thermodynamically favorable, both in the presence and in the absence of hydrogen. These results are a first step toward the development of processes for the carbon-mediated partial sequestration and selective oxidation of CO in a hydrogen atmosphere. We have elucidated the atomic scale mechanisms of activation and reduction of carbon dioxide on specifically designed catalytic surfaces via the rational manipulation of the surface properties that can be achieved by combining transition metal thin films on oxide

    Highlights: • A novel risk assessment method considering the ICPIs is proposed. • The protection and monitoring system as the ICPIs applications are studied. • The uncertainty of results is analyzed in addition to expected average results. • ICPIs impacts due to DG penetrations under various DG technologies are analyzed. • The well-being criteria have been provided in addition to reliability indices. - Abstract: The cyber failures such as failures in protection and monitoring systems will not stop the operation or change the behavior of the power system instantly but will adversely affect the performance of the power system against the potential failure. Such indirect cyber-power interdependencies (ICPIs) may either intensify the probability of future failures or postpone the repercussion to the present failure of the power elements. The much less effort has been devoted in literature to investigate the ICPIs impacts, particularly in stochastic simulating space. In this paper, a novel stochastic-based reliability evaluation method which considers the ICPIs impacts under various uncertain parameters is proposed. The consideration of uncertainty regarding the renewable distributed generation (DG) units, consumption patterns, power and cyber elements, and ICPIs is one of the most important contributions of the proposed method. Further, a novel stochastic-based state upgrading is introduced to concern the ICPIs of protection and monitoring systems. By using the proposed state upgrading methodology, it is possible to evaluate the reliability of smart grid based on ICPIs by using conventional reliability evaluation methods. The proposed risk assessment methodology is applied to an actual distribution grid. The several sensitivity studies are performed to gain insight into how the penetration level of DG units under various DG technology scenarios can affect the ICPIs impacts on the risk level of smart grid. The test results show that regardless of the DG

    Palsy of dorsiflexion, or foot drop, may be due to degenerative lumbar disease and amenable to posterior spinal decompression. The objective of this study is to measure prognostic factors of and time to foot drop improvement after posterior lumbar decompression. We retrospectively reviewed 71 patients undergoing first-time, posterior lumbar decompression for foot drop due to degenerative spinal disease. Patient sex, age, comorbidities (Charlson Comorbidity Index), preoperative anterior tibialis strength (manual muscle testing, MMT), and duration of foot drop were ascertained from clinical notes. Prognostic factors affecting foot drop improvement were calculated with a discrete time proportional hazards model, in which follow-up times and outcome measures were binned into six time intervals: 1 week, 6 weeks, 3 months, 6 months, 1 year, and ≥ 1 year. Of the 71 patients, the mean age was 54.6 ± 16.0 years, and 66.2% (n=47) were males. The mean Charlson Comorbidity Index was 2.42. During a mean follow-up of 30.4 months, dorsiflexion function improved postoperatively in 73.2% (n=52) of patients. The median time to surgery from onset of foot drop was within 6 weeks, and the median preoperative MMT strength of patients with foot drop improvement was 3. Following a discrete-time proportional hazards model, duration of anterior tibialis palsy (HR=0.67, P=0.004) and preoperative muscle strength (HR=1.10, P=0.010) were significant predictors of foot drop improvement. Following an adjusted Kaplan-Meier analysis, the median time to foot drop improvement was within 6 weeks of surgical intervention. Preoperative muscle strength and palsy duration were statistically significant predictors of foot drop improvement. Furthermore, the median time to improvement was 6 weeks.

    2006-01-01

    The paper is aimed at showing how demand-side policies for increasing inner demand elasticity could help in reducing market inefficiencies generated by transfer limits on interconnections, with a special regard to energy imports dependent countries. In order to develop the studies in a realistic environment, a model for the Italian electricity market has been developed. Test results show effects of variations in demand elasticity on the national social surplus and congestion costs. It will be shown how an increase of demand elasticity can counterbalance the need of additional transfer capacity in reducing cross-border congestions. (author)

    Full Text Available We report a case of a Singaporean who acquired Zika virus (ZIKV during a visit to Cuba. The infection was confirmed using molecular and serological methods. This report highlights potential drawbacks of using IgG serology for diagnosis of flavivirus infections in endemic regions. The low viremia detected during the early phase of this case resulted in low mosquito infectivity rates, suggesting the possibility of ZIKV transmission prior to clinical onset. The report also emphasizes the challenges of public health interventions for Zika fever and the importance of sustaining a low vector population to reduce the risk of arbovirus transmission in vulnerable regions.

  4. Spatial decoupling of agricultural production and consumption: quantifying dependences of countries on food imports due to domestic land and water constraints

    Fader, Marianela; Gerten, Dieter; Lucht, Wolfgang; Krause, Michael; Cramer, Wolfgang

    2013-01-01

    In our globalizing world, the geographical locations of food production and consumption are becoming increasingly disconnected, which increases reliance on external resources and their trade. We quantified to what extent water and land constraints limit countries’ capacities, at present and by 2050, to produce on their own territory the crop products that they currently import from other countries. Scenarios of increased crop productivity and water use, cropland expansion (excluding areas prioritized for other uses) and population change are accounted for. We found that currently 16% of the world population use the opportunities of international trade to cover their demand for agricultural products. Population change may strongly increase the number of people depending on ex situ land and water resources up to about 5.2 billion (51% of world population) in the SRES A2r scenario. International trade will thus have to intensify if population growth is not accompanied by dietary change towards less resource-intensive products, by cropland expansion, or by productivity improvements, mainly in Africa and the Middle East. Up to 1.3 billion people may be at risk of food insecurity in 2050 in present low-income economies (mainly in Africa), if their economic development does not allow them to afford productivity increases, cropland expansion and/or imports from other countries.

    Total number of cells, their viability and ability to adhesion were examined in surface alveolar macrophages isolated from rat livers after exposure to sulphur dioxide during 2, 4 and 6 weeks (0.05, 0.5, 1.0 and 5.0 mg/m3); to nitrogen oxide during 5, 8 and 15 hours, 28 and 56 days (19 mg/m3) and to carbon monoxide during 2, 28 and 56 days (0.01% or 10 MAC). In the experiment with exposure to sulphur dioxide, the activity of enzymes of varying localization in the macrophages - soluble in the cytoplasm (lactate dehydrogenase) and connected with subcellular structures - lysosomes (beta-galactosidase, beta-glucosidase and acid phosphatase) was tested by means of biochemical methods in parallel with cytological examinations. Low concentrations of various chemical contaminants of the atmospheric air (sulphur dioxide, nitrogen oxides, carbon monoxide) have an unfavourable biological effect on rats, manifest in the impairment of local immunity, i.e., decreased number of alveolar macrophages, disturbance of their viability and reduced ability of the macrophages to adhesion. At the same time, sulphur dioxide induces enzyme disorganization in lactate dehydrogenase and in a number of lysosomal enzymes of the macrophages. These results serve as a basis for the recommendation of cytobiochemical methods of elaborating methodological approaches to the regulation of environmental factors. Alveolar macrophages as a constituent part of the mononuclear phagocytic system ensuring local non-specific and specific resistance of the organism form one of the most important cellular mechanisms of protection of the organism against the harmful effect of environmental factors including chemical contaminants of the atmospheric air (1, 2).

  9. Radiation and Background Levels in a CLIC Detector due to Beam-Beam Effects Optimisation of Detector Geometries and Technologies

    Sailer, André; Lohse, Thomas

    2013-01-10

    The high charge density---due to small beam sizes---and the high energy of the proposed CLIC concept for a linear electron--positron collider with a centre-of-mass energy of up to 3~TeV lead to the production of a large number of particles through beam-beam interactions at the interaction point during every bunch crossing (BX). A large fraction of these particles safely leaves the detector. A still significant amount of energy will be deposited in the forward region nonetheless, which will produce secondary particles able to cause background in the detector. Furthermore, some particles will be created with large polar angles and directly cause background in the tracking detectors and calorimeters. The main sources of background in the detector, either directly or indirectly, are the incoherent $mathrm{e}^{+}mathrm{e}^{-}$ pairs and the particles from $gammagamma ightarrow$ hadron events. The background and radiation levels in the detector have to be estimated, to study if a detector is feasible, that can han...

    Important innovations in the development of the new generation of drilling jumbos led to an increase in the performance of conventional drivage technology, which had previously not been considered possible. An important factor in addition to the high drilling rate is the greater precision of the kinematics. This permits important cost savings on concrete and re-profiling. At the same time customer requirements such as the pre-drilling technology, recording of drilling parameters, profile monitoring and communication engineering were implemented in this new generation of drilling jumbos.

    Understanding the excretion and treatment of human waste (feces and urine) in low and middle income countries (LMICs) is necessary to design appropriate waste management strategies. However, excretion and treatment are often difficult to quantify due to decentralization of excreta management. We address this gap by developing a mechanistic, stochastic model to characterize phosphorus, nitrogen, biochemical oxygen demand (BOD), and fecal coliform pollution from human excreta for 108 LMICs. The model estimates excretion and treatment given three scenarios: (1) use of existing sanitation systems, (2) use of World Health Organization-defined "improved sanitation", and (3) use of best available technologies. Our model estimates that more than 10(9) kg/yr each of phosphorus, nitrogen and BOD are produced. Of this, 22(19-27)%, 11(7-15)%, 17(10-23)%, and 35 (23-47)% (mean and 95% range) BOD, nitrogen, phosphorus, and fecal coliforms, respectively, are removed by existing sanitation systems. Our model estimates that upgrading to "improved sanitation" increases mean removal slightly to between 17 and 53%. Under the best available technology scenario, only approximately 60-80% of pollutants are treated. To reduce impact of nutrient and microbial pollution on human and environmental health, improvements in both access to adequate sanitation and sanitation treatment efficiency are needed.

    The aim of the present study was to explore and analyze accounts of social interactions and relationships with family, workmates, and friends supplied by persons with experience of sickness absence due to back, neck, or shoulder diagnoses. The focus was on experiences that seemed to involve positive and negative self-evaluative aspects, and therefore may be important to the self-conception and self-esteem of the absentee, and possibly to return to work. The interviewees were women and men between 25 to 34 years of age who had been sickness certified due to back, neck, or shoulder diagnosis. A descriptive and explorative method was used to analyze data from five focus-group interviews. The importance of being supported and encouraged by family members, and the importance of feeling needed at work as well as being part of a social context were aspects stressed by the respondents. Our results indicate that these interactions and relations are important to the absentees' self-esteem, and that this should be taken into account when discussing rehabilitation efforts.

    The project has provided the draft regulatory policies and guides regarding the quality assurance of software used to I and C systems important to safety in nuclear power plants, differentiated V and V activities by safety classes which are important elements in ensuring software quality assurance, and suggested V and V techniques to be applied, regulatory guides and checklists for reviewing software important to safety. The project introduced the classification concepts on software quality assurance. The I and C systems important to safety are classified into IC-1, IC-2, IC-3, and Non-IC as based on safety classifications. And the software used to these I and C systems are classified into 3 categories, say, safety-critical software, safety-related software, and non-safety software, in the light of safety importance of functions to be performed. Based upon these safety classifications, the extent of software V and V activities by each class has been differentiated each other. On the other hand, the project has divided software important to safety into newly-developed software and previously-developed software in terms of design and implementation, and provided the draft regulatory guides on each type of software, for instance, newly-developed software, previously-developed software, and software tools

    Intelligent assistive technologies that complement and extend human abilities have proliferated in recent years. Service robots, home automation equipment, and other digital assistant devices possessing artificial intelligence are forms of assistive technologies that have become popular in society. Older adults (>55 years of age) have been identified by industry, government, and researchers as a demographic who can benefit significantly from the use of intelligent assistive technology to support various activities of daily living. The purpose of this scoping review is to summarize the literature on the importance of the concept of "trust" in the adoption of intelligent assistive technologies to assist aging in place by older adults. Using a scoping review methodology, our search strategy will examine the following databases: ACM Digital Library, Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, PsycINFO, Scopus, and Web of Science. Two reviewers will independently screen the initial titles obtained from the search, and these results will be further inspected by other members of the research team for inclusion in the review. This review will provide insights into how the concept of trust is actualized in the adoption of intelligent assistive technology by older adults. Preliminary sensitization to the literature suggests that the concept of trust is fluid, unstable, and intimately tied to the type of intelligent assistive technology being examined. Furthermore, a wide range of theoretical lenses that include elements of trust have been used to examine this concept. This review will describe the concept of trust in the adoption of intelligent assistive technology by older adults, and will provide insights for practitioners, policy makers, and technology vendors for future practice. ©Josephine McMurray, Gillian Strudwick, Cheryl Forchuk, Adam Morse, Jessica Lachance, Arani Baskaran, Lauren

    A paradigm shift seems to emerge, not only in industrial engineering ("Industry 4.0") but also in medicine: we are on the threshold to "Medicine 4.0". For many years, molecular biology had a leading position in life sciences, but today scientists start realizing that microelectronic systems, due to an increasing miniaturization, are reaching the scale of human cells and consequently can be used for therapeutic approaches. This article shows how microelectronics can play a major role in modern medicine, through the example of customized chemotherapy. This consists in determining, before the beginning of the treatment, what kind of chemotherapy or drug combination will be most effective for a given patient, and at which dose. This of course allows the lessening of a patient burden during treatment, but also to be more efficient and, in the long run, to save money. In order to do this, we have developed the Intelligent Microplate Reader (IMR), which allows us to accurately test different drugs on living cells by mimicking part of their usual environment. © 2018 médecine/sciences – Inserm.

    Heritage organizations in Flanders started using thesauri fairly recently compared to other countries. This paper starts with examining the historical use of thesauri and controlled vocabularies in computer systems by the Flemish Government dealing with immovable cultural heritage. Their evolution from simple, flat, controlled lists to actual thesauri with scope notes, hierarchical and equivalence relations and links to other thesauri will be discussed. An explanation will be provided for the evolution in our approach to controlled vocabularies, and how they radically changed querying and the way data is indexed in our systems. Technical challenges inherent to complex thesauri and how to overcome them will be outlined. These issues being solved, thesauri have become an essential feature of the Flanders Heritage inventory management system. The number of vocabularies rose over the years and became an essential tool for integrating heritage from different disciplines. As a final improvement, thesauri went from being a core part of one application (the inventory management system) to forming an essential part of a new general resource oriented system architecture for Flanders Heritage influenced by Linked Data. For this purpose, a generic SKOS based editor was created. Due to the SKOS model being generic enough to be used outside of Flanders Heritage, the decision was made early on to develop this editor as an open source project called Atramhasis and share it with the larger heritage world.

    Full Text Available Groups of fatty acids (FAs in milk fat can have positive and negative impact on consumer health. Profile of FAs could be influenced by dairy cow nutrition, breed, milk yield level et cetera. The question is what relationships the FAs could have to quality of milk products? Relationships between FAs and their groups to selected milk indicators were studied in Czech Fleckvieh and Holstein cows (64 bulk milk samples. There were 8 herds in 2-year investigation during winter and summer season. The relationship of saturated FAs (SAFA; 66.22% was significant only to lactose (L content (0.290; P < 0.05. The relationships of monounsaturated FAs (MUFA; 29.21% to milk indicators (MIs were in­si­gni­fi­cant (P > 0.05.

The higher CLA levels were connected in this way with: higher fat content; lower lactose content; lower alcohol stability; lower streptococci count in yoghurt; lower streptococci/lactobacilly ratio in yoghurt. The PUFA and CLA representation decreased with L increase. Simultaneously some technological milk properties such as alcohol sta­bi­li­ty and fermentationability were slightly improved.

  13. A survey of selected neutron-activation reactions with short-lived products of importance to fusion reactor technology

    1994-11-01

    The status of the cross sections for production of short-lived radioactivities in the intense high-energy neutron fields associated with D-T fusion reactors is investigated. The main concerns relative to these very radioactive isotopes are with radiation damage to sensitive components such as superconducting magnets, the decay-heat problem and the safety of personnel during operation of the facility. The present report surveys the status of nuclear data required to assess these problems. The study is limited to a few high-priority nuclear reactions which appear to be of critical concern in this context. Other reactions of lesser concern are listed but are not treated in the present work. Among the factors that were considered in defining the relevant reactions and setting priorities are: quantities of the elemental materials in a fusion reactor, isotopic abundances within elemental categories, the decay properties of the induced radioactive byproducts, the reaction cross sections, and the nature of the decay radiations. Attention has been focused on radioactive species with half lives in the range from about 1 second to 15 minutes. Available cross-section and reaction-product decay information from the literature has been compiled and included in the report. Uncertainties have been estimated by examining several sets of experimental as well as evaluated data. Comments on the general status of data for various high-priority reactions are offered. On the basis of this investigation, it has been found that the nuclear data are in reasonably good shape for some of the most important reactions but are unacceptable for others. Based on this investigation, the reactions which should be given the greatest attention are: 16 O(n,p) 16 N, 55 Mn(n,p) 55 Cr, 57 Fe(n,p) 57 Mn, 186 W(n,2n) 185m W, and 207 Pb(n,n') 207m Pb.

    The majority of validation done on the Roland-Morris Disability Questionnaire (RMDQ) has been in patients with mild or moderate disability. There is paucity of research focusing on the psychometric quality of the RMDQ in patients with severe disability. To evaluate the psychometric quality of the RMDQ in patients with severe disability. Observational clinical study. The sample consisted of 214 patients with painful vertebral compression fractures who underwent vertebroplasty or kyphoplasty. The 23-item version of the RMDQ was completed at two time points: baseline and 30-day postintervention follow-up. With the two-parameter logistic unidimensional item response theory (IRT) analyses, we derived the range of scores that produced reliable measurement and investigated the minimal clinically important difference (MCID). Scores for 214 (100%) patients at baseline and 108 (50%) patients at follow-up did not meet the reliability criterion of 0.90 or higher, with the majority of patients having disability due to back pain that was too severe to be reliably measured by the RMDQ. Depending on methodology, MCID estimates ranged from 2 to 8 points and the proportion of patients classified as having experienced meaningful improvement ranged from 26% to 68%. A greater change in score was needed at the extreme ends of the score scale to be classified as having achieved MCID using IRT methods. Replacing items measuring moderate disability with items measuring severe disability could yield a version of the RMDQ that better targets patients with severe disability due to back pain. Improved precision in measuring disability would be valuable to clinicians who treat patients with greater functional impairments. Caution is needed when choosing criteria for interpreting meaningful change using the RMDQ. Copyright © 2017 Elsevier Inc. All rights reserved.

    Milk is a major source of nutrients, but can also be a vehicle for zoonotic foodborne diseases, especially when raw milk is consumed. In Africa, poor processing and storage conditions contribute to contamination, outgrowth and transmission of pathogens, which lead to spoilage, reduced food safety and security. Fermentation helps mitigate the impact of poor handling and storage conditions by enhancing shelf life and food safety. Traditionally-fermented sour milk products are culturally accepted and widely distributed in Africa, and rely on product-specific microbiota responsible for aroma, flavor and texture. Knowledge of microbiota and predominant, technologically important microorganisms is critical in developing products with enhanced quality and safety, as well as sustainable interventions for these products, including Africa-specific starter culture development. This narrative review summarizes current knowledge of technologically-important microorganisms of African fermented dairy products (FDP) and raw milk, taking into consideration novel findings and taxonomy when re-analyzing data of 29 publications covering 25 products from 17 African countries. Technologically-important lactic acid bacteria such as Lactococcus lactis and Streptococcus infantarius subsp. infantarius (Sii), Lactobacillus spp. and yeasts predominated in raw milk and FDP across Africa. Re-analysis of data also suggests a much wider distribution of Sii and thus a potentially longer history of use than previously expected. Therefore, evaluating the role and safety of African Sii lineages is important when developing interventions and starter cultures for FDP in Africa to enhance food safety and food security. In-depth functional genomics, epidemiologic investigations and latest identification approaches coupled with stakeholder involvement will be required to evaluate the possibility of African Sii lineages as novel food-grade Streptococcus lineage.

    Successful management of health conditions in older population is determined by strategic involvement of a professional team of careers and by empowering patients and their caregivers to take over a central role and responsibility in the daily management of condition. Identifying, structuring and ranking the most important needs related to these aspects could pave the way for improved strategies in designing systems and technological solutions supporting user empowerment. This paper presents the preliminary results of a study aiming to elicit these needs. Healthcare professionals, working together in the European and Innovation Partnership on Active and Healthy Ageing (EIP-AHA) initiative, have defined a set of needs and factors that have been organized in two hierarchies around the concepts of patient activation and proactive and prepared care team, defined in the Chronic Care Model. The two hierarchies have been mapped, by a team of experts in computer science, with technologies and solutions that could facilitate the achievement of the identified needs.

    Although Health Technology Assessment (HTA) is increasingly used to support evidence-based decision-making in health care, several barriers and facilitators for the use of HTA have been identified. This best-worst scaling (BWS) study aims to assess the relative importance of selected barriers and facilitators of the uptake of HTA studies in Austria. A BWS object case survey was conducted among 37 experts in Austria to assess the relative importance of HTA barriers and facilitators. Hierarchical Bayes estimation was applied, with the best-worst count analysis as sensitivity analysis. Subgroup analyses were also performed on professional role and HTA experience. The most important barriers were 'lack of transparency in the decision-making process', 'fragmentation', 'absence of appropriate incentives', 'no explicit framework for decision-making process', and 'insufficient legal support'. The most important facilitators were 'transparency in the decision-making process', 'availability of relevant HTA research for policy makers', 'availability of explicit framework for decision-making process', 'sufficient legal support', and 'appropriate incentives'. This study suggests that HTA barriers and facilitators related to the context of decision makers, especially 'policy characteristics' and 'organization and resources' are the most important in Austria. A transparent and participatory decision-making process could improve the adoption of HTA evidence.

Final decision should take into account the societal value of new therapies.Objective: This perspective paper discusses the socio-economic burden of disease as a specific reimbursement decision-making criterion and calls for the inclusion of it as a counterbalance to the cost-effectiveness and budget impact criteria.Results/Conclusions: Socio-economic burden is a decision-making criterion, accounting for diseases, for which the assessed medical technology is indicated. This indicator is usually researched through cost-of-illness studies that systematically quantify the socio-economic burden of diseases on the individual and on the society. This is a very important consideration as it illustrates direct budgetary consequences of diseases in the health system and indirect costs associated with patient or carer productivity losses. By measuring and comparing the socio-economic burden of different diseases to society, health authorities and payers could benefit in optimizing priority setting and resource allocation.New medical technologies, especially innovative therapies, present an excellent case study for the inclusion of socio-economic burden in reimbursement decision-making. Assessment and appraisal have been greatly concentrated so far on cost-effectiveness and budget impact, marginalizing all other considerations. In this context, data on disease burden and inclusion of explicit criterion of socio-economic burden in reimbursement decision-making may be highly beneficial. Realizing the magnitude of the lost socio-economic contribution resulting from diseases in question could be a reasonable way for policy makers to accept a higher valuation of innovative therapies.

  20. Technological Style is History

    DEFF Research Database (Denmark)

    Blond, Lasse

    The effort to comprehend innovation across cultures and time highlights the importance of the explicating factors external to technology. It becomes relevant to nuance or differentiate the understanding of social and cultural responses to adopted technologies by recognizing that technology shapes...... culture, and just as importantly that culture shapes technology. By looking at a recent transfer of technology this reciprocal exchange is elaborated by considering the cultural or contextual influence in the adaptation of technology. In this connection the notion of technological style is revisited...... by questioning whether it pays due attention to the non-technical factors of the process? In order to compensate for the deficiencies of the technological style as a sensitizing device the concept of sociotechnical style is introduced – a concept more in tune with resent research in technology studies....

    Full Text Available The mycotoxins associated with specific Fusarium fungal infections of grains are a threat to global food and feed security. These fungal infestations are referred to as Fusarium Head Blight (FHB and lead to Fusarium Damaged Kernels (FDK. Incidence of FDK >0.25% will lower the grade, with a tolerance of 5% FDK for export feed grain. During infestation, the fungi can produce a variety of mycotoxins, the most common being deoxynivalenol (DON. Fusarium Damaged Kernels have been associated with reduced crude protein (CP, lowering nutritional, functional and grade value. New technology has been developed using Near Infrared Transmittance (NIT spectra that estimate CP of individual kernels of wheat, barley and durum. Our objective is to evaluate the technology's capability to reduce FDK and DON of downgraded wheat and ability to salvage high quality safe kernels. In five FDK downgraded sources of wheat, the lowest 20% CP kernels had significantly increased FDK and DON with the high CP fractions having decreased FDK and DON, thousand kernel weights (TKW and bushel weight (Bu. Strong positive correlations were observed between FDK and DON (r = 0.90; FDK and grade (r = 0.62 and DON and grade (r = 0.62. Negative correlations were observed between FDK and DON with CP (r = −0.27 and −0.32; TKW (r = −0.45 and −0.54 and Bu (r = −0.79 and −0.74. Results show improved quality and value of Fusarium downgraded grain using this technology.

    Purpose To identify from a health-care professionals' perspective whether smartphones are used by children and adolescents with acquired brain injury as memory aids; what factors predict smartphone use and what barriers prevent the use of smartphones as memory aids by children and adolescents. Method A cross-sectional online survey was undertaken with 88 health-care professionals working with children and adolescents with brain injury. Results Children and adolescents with brain injury were reported to use smartphones as memory aids by 75% of professionals. However, only 42% of professionals helped their clients to use smartphones. The only factor that significantly predicted reported smartphone use was the professionals' positive attitudes toward assistive technology. Several barriers to using smartphones as memory aids were identified, including the poor accessibility of devices and cost of devices. Conclusion Many children and adolescents with brain injury are already using smartphones as memory aids but this is often not facilitated by professionals. Improving the attitudes of professionals toward using smartphones as assistive technology could help to increase smartphone use in rehabilitation. Implications for Rehabilitation Smartphones could be incorporated into rehabilitation programs for young people with brain injury as socially acceptable compensatory aids. Further training and support for professionals on smartphones as compensatory aids could increase professionals' confidence and attitudes in facilitating the use of smartphones as memory aids. Accessibility could be enhanced by the development of a smartphone application specifically designed to be used by young people with brain injury.

    A challenge when groups from different disciplines work together in implementing health information technology (HIT) in a health-care context is that words often have different meanings depending upon work practices, and definition of situations. Accessibility is a word commonly associated with HIT implementation. This study aimed to investigate different meanings of accessibility when implementing HIT in everyday work practice in a health-care context. It focused on the perspective of nurses to highlight another view of the complex relationship between HIT and information in a health-care context. This is a qualitative study influenced by institutional ethnographic. District nurses and student nurses were interviewed. The results indicate that when implementing HIT accessibility depends on working routines, social structures and patient relationship. The findings of the study suggest that interaction needs to take on a more important role when implementing HIT because people act upon words from the interpreted meaning of them. Symbolic interactionism is proposed as a way to set a mutual stage to facilitate an overall understanding of the importance of the meaning of words. There is a need for making place and space for negotiation of the meaning of words when implementing HIT in everyday work practice.

    Full Text Available This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM and active power filter (APF inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.

    The technological trajectory is the pathway through which an innovative technology develops as it matures. In this paper we model the technological trajectory for a number of energy technologies by analysing technological change (characterised by unit-level capacity up-scaling) and diffusion (characterised by growth in cumulative deployed capacity) using sigmoidal 5 Parameter Logistic (5PL) functions, observed and reported as a function of unit deployment. Application of 5PL functions allows inference of technology development milestones, such as initiation of unit-level up-scaling or industry growth, with respect to the number of unit deployments. This paper compares the technological trajectory followed by mature energy technologies to that being attempted by those in the nascent wave and tidal energy sectors, particularly with regards to unit deployment within a formative phase of development. We identify that the wave and tidal energy sectors are attempting to bypass a formative phase of technological development, which is not in line with technological trajectories experienced by historic energy technologies that have successfully diffused into widespread commercial application, suggesting that demand-pull support mechanisms are premature, and a need for technology push focused policy support mechanisms is vital for stimulating economically sustainable development and deployment of wave and tidal stream energy. - Highlights: • Technology up-scaling should take place after a formative phase of development. • Ocean energy technologies are attempting to bypass a formative phase. • Unit up-scaling has taken place prior to successful technology demonstration. • The cost of the formative phase may be insurmountable using MW-scale technology. • A shift in the research, development and innovation environment is necessary.

    Many individuals with traumatic brain injury (TBI) are young and could have many years of productivity ahead of them. However, cognitive impairments may hinder individuals' ability to perform daily tasks. Assistive technology for cognition (ATC) can be effective in helping compensate for cognitive impairments. This study examined the current state of the research on using ATCs to support daily activities for individuals with cognitive disabilities that are due to TBI. A comprehensive systematic literature search was performed to identify peer-reviewed articles published between 2000 and 2015. To evaluate the nature of the research, qualitative data were extracted pertaining to recruitment, participant characteristics, intervention design, type of ATCs and their functions, matching individuals with ATCs, training for using the ATC, and outcomes. Research examining the effectiveness of ATCs as everyday compensatory tools for cognitive impairments that are due to TBI is limited. The majority of studies were case studies or quasi-experimental studies with small sample sizes. Studies showed positive associations between use of ATCs and individuals' abilities to perform tasks regardless of age, TBI severity, and time since injury. Future research should assess the match between the individual and the technology, study the impact of training on using ATCs, and analyze the usability of ATCs.

  15. Importance of Engineering History Education

    It is needless to cite the importance of education for succeed of engineering. IEEJ called for the establishment of ICEE in 1994, where the education is thought highly of, though its discussion has not been well working. Generally speaking, education has been one of the most important national strategies particularly at a time of its political and economical development. The science and technology education is, of course, not the exemption. But in these days around 2000 it seems that the public pays little attention on the science and technology, as they are quite day to day matters. As the results, for instance, such engineering as power systems and electric heavy machines are referred to as “endangered”. So fur, many engineers have tried not to be involved in social issues. But currently they can not help facing with risks of social issues like patent rights, troubles and accidents due to application of high technology, information security in the use of computers and engineering ethics. One of the most appropriate ways for the risk management is to learn lessons in the past, that is, history, so that the idea suggested in it could be made full use for the risk management. The author cited the global importance of education, particularly of engineering history education for engineering ethics, in the ICEE 2010 held in Bussan, Korea, as the 16th anniversary.

    Laser flare photometry (LFP) is an objective and quantitative method to measure intraocular inflammation. The LFP technology was developed in Japan and has been commercially available since 1990. The aim of this work was to review the application of LFP in uveitis practice in Europe compared to Japan where the technology was born. We reviewed PubMed articles published on LFP and uveitis. Although LFP has been largely integrated in routine uveitis practice in Europe, it has been comparatively neglected in Japan and still has not received FDA approval in the USA. As LFP is the only method that provides a precise measure of intraocular inflammation, it should be used as a gold standard in uveitis centres worldwide.

    For a reduction in friction and abrasion of automotive engine piston rings, cams, shims, etc., which grow aggravated due to increasingly severe operating conditions, studies are made to develop a process technology for the creation of tribo-materials through the application of the ion process technology which is capable of controlling nanometer-scale structures. In the study of nano-structure control process, various types of coat forming technologies are employed, which are ion plating, plasma CVD (chemical vapor deposition), and sputtering, for the formation of Ti-Si-N based coatings, Cr-Si-N based coatings, etc. As the result, efforts are now increasingly focused on the arc ion plating technology. In the study of composite tribo-materials, since it is found that high density and high adhesion are achieved in Ti-Si-N based and Cr-Si-N based coatings in particular, their use as coatings for cams, shims, and piston rings is evaluated. In the study of the optimization of matrix layer materials, the sliding characteristics of nitride coatings are investigated, with their formation conditions varied for the control of coating hardness and orientation.

  20. Human due diligence.

    Most companies do a thorough job of financial due diligence when they acquire other companies. But all too often, deal makers simply ignore or underestimate the significance of people issues in mergers and acquisitions. The consequences are severe. Most obviously, there's a high degree of talent loss after a deal's announcement. To make matters worse, differences in decision-making styles lead to infighting; integration stalls; and productivity declines. The good news is that human due diligence can help companies avoid these problems. Done early enough, it helps acquirers decide whether to embrace or kill a deal and determine the price they are willing to pay. It also lays the groundwork for smooth integration. When acquirers have done their homework, they can uncover capability gaps, points of friction, and differences in decision making. Even more important, they can make the critical "people" decisions-who stays, who goes, who runs the combined business, what to do with the rank and file-at the time the deal is announced or shortly thereafter. Making such decisions within the first 30 days is critical to the success of a deal. Hostile situations clearly make things more difficult, but companies can and must still do a certain amount of human due diligence to reduce the inevitable fallout from the acquisition process and smooth the integration. This article details the steps involved in conducting human due diligence. The approach is structured around answering five basic questions: Who is the cultural acquirer? What kind of organization do you want? Will the two cultures mesh? Who are the people you most want to retain? And how will rank-and-file employees react to the deal? Unless an acquiring company has answered these questions to its satisfaction, the acquisition it is making will be very likely to end badly.

    There are numerous challenges to overcome before information and communication technology (ICT) can achieve its full potential in process-oriented health-care organizations. One of these challenges is designing systems that meet users' needs, while reflecting a continuously changing organizational environment. Another challenge is to develop ICT that supports both the internal and the external stakeholders' demands. In this study a qualitative research strategy was used to explore the demands on ICT expressed by managers from functional and process units at a community hospitaL The results reveal a multitude of partially competing goals that can make the ICT development process confusing, poor in quality, inefficient and unnecessarily costly. Therefore, from the perspective of ICT development, the main task appears to be to coordinate the different visions and in particular clarify them, as well as to establish the impact that these visions would have on the forthcoming ICT application.

In this Niigataken-Chuetsuoki earthquake, there is almost no damage to the system, components and structure on safe also in the earthquake beyond assumption, and the validity of the design was checked. But, the situation peculiar to a big earthquake was also generated. The emergency plan room which should serve as a connection center with the exterior was not able to open a door and use at the beginning. Fire-extinguishing system piping fractured and self-defense fire fighting was not made. And so on. Discussion from the following three viewpoints was performed. 1st: The importance from a viewpoint which should maintain a function also with the disaster in case of an earthquake like an emergency plan room etc. 2nd: In the earthquake, since the safe system and un-safe system was influenced, the importance from a viewpoint which may have influence safely inquired when the un-safe system broke down. 3rd: Although it was not directly related safely, discussion from a viewpoint which influences fear of insecurity, such as taking out smoke, for example, was performed (author)

    Results of various studies suggest that multimedia ‘case methods’ (activities associated with case documentaries) have many benefits in university-based teacher education contexts. They can, for example, help to ‘bridge the gap’ between perspectives and practices held by academic teacher educators and those held by student-teachers - who may adhere to perspectives and practices commonly supported in schools. On the other hand, some studies, along with theoretical arguments, suggest that there are limits to the effectiveness of multimedia case methods - because, for example, they can never fully represent realities of teaching and learning in schools. Furthermore, often missing from multimedia case methods is the student-teacher in the role of teacher. To address these concerns, we modified an existing multimedia case method by associating it with a special practice teaching situation in a school context. Qualitative data analyzed using constant comparative methods suggest that student-teachers engaged in this modified multimedia case method developed relatively deep commitments to encouraging students to conduct technology design projects - a non-traditional practice in school science. Factors that appeared to influence development of this motivation included student-teachers’ pre-instructional perspectives about science and the personalization and contextualization inherent to the modified multimedia case method.

    Full Text Available Nowadays, there is an increasing need of new skills for PhD students to face the future labour market prospects. PhD graduates must have qualities attractive not only in academia but also outside, in both manufacture and service-oriented enterprises, in small innovative companies, and in the civil services and public administration, among others. To know what the needs of these future employees are, is of great importance to be able to improve their personal and academic formation. The aim of this work was, in the framework of the EC-funded ISEKI_Food 4 network, to evaluate the most desirable specific and soft skills that PhD students should acquire by the end of their doctoral studies. To this aim, several surveys were conducted and sent to the different stakeholders (academia and food industry partners in order to collect the information needed. Results showed that competences related to research skills and techniques, research management, personal effectiveness and communication skills were considered to be the most valuable skills to be acquired by our PhD students to meet the future needs of the labour market.  The importance of these skills was appreciated differently, depending on the stakeholder. To sum up, some recommendations to integrate such valuable skills into the curricula of the PhD student are given.

    In contrast to conventional approaches used for diagnostics (i.e. when inspection results are used as data for numerical calculative strength analysis) the specific feature of the new proposed approach consists in a fact that the approach is based on application of the 'inverse problem' principle. As regards to implementation of the proposed new approach, first of all a detailed numerical calculative finite-element model of the monitored equipment must be developed. Results of preliminary calculations allow to make reasonable selection of definite installation places and types of control sensors intended for more effective and precise work of the calculative model. As a rule, the control sensors are high-temperature strain gauges, temperature probes, pressure, acceleration and displacement sensors, as well as acoustic-emission and ultrasonic sensors used for monitoring of actual defectiveness kinetics in the zone of potential damaging. All the sensors work in the on-line mode during several years of operation, the optimal frequency of data records is selected, all recorded data after prompt processing are transferred to the finite-element calculative modulus for strength calculations of a monitored zone. Software for strength calculation must be based on an individual calculative code, since it should also work in the on-line mode. Comprehensible strength analysis in conjunction with obtained results of defectiveness kinetics monitoring allow not only to foresee the most unfavorable scenario resulting to damaging, but also to have a possibility for prompt analysis and elaboration of compensating measures allowing to reduce operational loadings. In the report the results of development and practical application of the new approach at NPPs and corresponding technology are presented. (author)

    inserting of the control rods. Calculations show that a possible rupture on the steam line will near result in a reaching of the plastic yield value for the extensions of the bolts fastening the shroud head to the core shroud. These facts will state reasons for deeper analyses of these scenarios. The feed water spargers: The feed water spargers have been exposed to relative extensive cracking. The cracks arose during normal operation. This was due to thermal fatigue caused by a combination of thermal fluctuations, cold working and surface roughness. During the years measures have been taken to mitigate this. A part from a cracked feed-water sparger, which is sucked into a recirculation line, may possibly damage the corresponding pump. The debris created thereby might end up in lower dome of the reactor vessel. Special investigations have shown that such fragments are unlikely to be carried by the coolant flow up to the inlets of the core coolant channels. For that reason there is no motivation to do a deeper analysis in present situation. Steam drier and its upper and lower supports: The scenarios where steam drier takes part start because of its supports break. The likelihood that this happens is very low, and in addition it will not have serious consequences. Accordingly it is not motivated to do deeper analyses regarding this scenario. The Core shroud: The analysis that has been done here has not treated the consequences of a circumferential crack. On the other hand limit cracking has been studied. No serious consequences have been identified as loss of the scram function and core cooling. For that reason there it is not motivated to do deeper analyses in present situation. The core shroud support: Scenarios, which include a collapse of the core shroud support, can cause very serious consequences. However the probability for an initiating of these kinds of scenarios is very low. Mainly depending on the fact that the core shroud support is oversized and no failure

    There are significant developments underway in new types of actuators for power plant active components. Many of these make use of digital technology to provide a wide array of benefits in performance of the actuators and in reduced burden to maintain them. These new product offerings have gained considerable acceptance in use in process plants. In addition, they have been used in conventional power generation very successfully. This technology has been proven to deliver the benefits promised and substantiate the claims of improved performance. The nuclear industry has been reluctant to incorporate digital actuator technology into nuclear plant designs due to concerns due to a number of concerns. These could be summarized as cost, regulatory uncertainty, and a certain comfort factor with legacy analog technology. The replacement opportunity for these types of components represents a decision point for whether to invest in more modern technology that would provide superior operational and maintenance benefits. Yet, the application of digital technology has been problematic for the nuclear industry, due to qualification and regulatory issues. With some notable exceptions, the result has been a continuing reluctance to undertake the risks and uncertainties of implementing digital actuator technology when replacement opportunities present themselves. Rather, utilities would typically prefer to accept the performance limitations of the legacy analog actuator technologies to avoid impacts to project costs and schedules. The purpose of this report is to demonstrate that the benefits of digital actuator technology can be significant in terms of plant performance and that it is worthwhile to address the barriers currently holding back the widespread development and use of this technology. It addresses two important objectives in pursuit of the beneficial use of digital actuator technology for nuclear power plants: 1. To demonstrate the benefits of digital actuator

    A synthetic study was performed on some of those to whom Thorotrast had been injected, in Japan. In the epidemiological study of 147 war woundeds to whom Thorotrast had been injected, it was noted that the Thorotrast injection increased the mortality rate and the incidences of malignant hepatic tumor, liver cirrhosis, and hematological diseases. Clinical study of 44 of them showed that the Thorotrast injection resulted in liver and hematopoietic hypofunctions. Analysis of the dissection of the injected area in 118 cases showed malignant hepatic tumor in 63.5%, liver cirrhosis in 14.4% and hematological diseases in 10.2%. The total of the three types of disease was 88.1%. Histological classification showed that of the malignant hepatic tumors due to Thorotrast, hepatobiliary cancer and hemangioendothelioma of the liver were frequent. By the comparison of the absorbed dose in the liver of the malignant hepatic tumors due to Thorotrast with that of the cancers developed in animal experiments, it was noted that the carcinogenic dose was a mean of 2,000 - 3,000 rad by accumulated dose. It was elucidated that carcinogenesis and fibrination were primary in injury due to Thorotrast, i.e., late injury due to Thorotrast, and that the increase in the accumulated dose in rogans and the increase of the local dose due to the gigantic growth of Thorotrast granules in organs greatly influenced carninogenesis and fibrination.

    The Campos Basin is known as one of the most challenging deep water basins in the world. Currently there are thirty-seven platforms, more than a thousand oil wells, and about 4200 kilometers of submarine pipelines, having produced more than 1,2 billion barrels of oil per year and 15,7 million cubic meters of gas per day. The Campos Basin is responsible for more than 80% of Brazil's national production. Brazil intends to produce 2,2 million barrels of oil per day by 2007, when it will reach self-sufficiency. Therefore, the continued development of the offshore basins, such as Campos, Santos and Espirito Santo will be critical to meet this goal. In this context, the technological evolution of the vessels that render stimulation services is of fundamental importance to improve job quality, reduce time, protect with the environment, enable efficient communication, and ensure operational viability of new techniques. This paper reports on the history of this vessels, describing and illustrating new and state-of-the-art technology, historical cases of pioneering operations, data transmission in real time and the benefits for offshore operators with a global vision.

    The dose due to 40 K has been estimated. Potassium is one of the most abundant elements in nature, being approximately 2% of the Earth's crust. Potassium has three isotopes 39 K, 40 K and 41 K, two are stable while 40 K is radioactive with a half life of 1.2x10 9 years; there is 0.0117% 40 K-to-K ratio. Potassium plays an important role in plants, animals and humans growth and reproduction. Due to the fact that K is an essential element for humans, 40 K is the most abundant radioisotope in human body. In order to keep good health conditions K must be intake at daily basis trough food and beverages, however when K in ingested above the requirements produce adverse health effects in persons with renal, cardiac and hypertension problems or suffering diabetes. In 89.3% 40 K decays to 40 C through β-decay, in 10.3% decays through electronic capture and emitting 1.46 MeV γ-ray. K is abundant in soil, construction materials, sand thus γ-rays produced during 40 K decay contribute to external dose. For K in the body practically all 40 K decaying energy is absorbed by the body; thus 40 K contributes to total dose in humans and it is important to evaluate its contribution. In this work a set of 40 K sources were prepared using different amounts of KCl salt, a γ-ray spectrometer with a NaI(Tl) was characterized to standardized the sources in order to evaluate the dose due to 40 K. Using thermoluminescent dosemeters the dose due to 40 K was measured and related to the amount of 40 K γ-ray activity. (Author)

Hemodialysis is a complex treatment for chronic kidney disease (CKD and affects many outcomes. Apart from obvious outcomes, such as mortality, morbidity and health-related quality of life (HRQoL, others such as, concerning daily living or health care provision, may also be important. The aim of our study was to analyze to what extent the preferences for patient-relevant outcomes differed between various stakeholders. We compared preferences of stakeholders normally or occasionally involved in outcome prioritization (patients from a self-help group, clinicians and HTA authors with those of a large reference group of patients. Participants and methods: The reference group consisted of 4,518 CKD patients investigated previously. We additionally recruited CKD patients via a regional self-help group, nephrologists via an online search and HTA authors via an expert database or personal contacts. All groups assessed the relative importance of the 23 outcomes by means of a discrete visual analog scale. We used descriptive statistics to rank outcomes and compare the results between groups. Results: We received completed questionnaires from 49 self-help group patients, 19 nephrologists and 18 HTA authors.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    2013-01-01

    Human space exploration has always been heavily influenced by goals to achieve a specific mission on a specific schedule. This approach drove rapid technology development, the rapidity of which adds risks as well as provides a major driver for costs and cost uncertainty. The National Aeronautics and Space Administration (NASA) is now approaching the extension of human presence throughout the solar system by balancing a proactive yet less schedule-driven development of technology with opportunistic scheduling of missions as the needed technologies are realized. This approach should provide cost effective, low risk technology development that will enable efficient and effective manned spaceflight missions. As a first step, the NASA Human Spaceflight Architecture Team (HAT) has identified a suite of critical technologies needed to support future manned missions across a range of destinations, including in cis-lunar space, near earth asteroid visits, lunar exploration, Mars moons, and Mars exploration. The challenge now is to develop a strategy and plan for technology development that efficiently enables these missions over a reasonable time period, without increasing technology development costs unnecessarily due to schedule pressure, and subsequently mitigating development and mission risks. NASA's Johnson Space Center (JSC), as the nation s primary center for human exploration, is addressing this challenge through an innovative approach in allocating Internal Research and Development funding to projects. The HAT Technology Needs (TechNeeds) Database has been developed to correlate across critical technologies and the NASA Office of Chief Technologist Technology Area Breakdown Structure (TABS). The TechNeeds Database illuminates that many critical technologies may support a single technical capability gap, that many HAT technology needs may map to a single TABS technology discipline, and that a single HAT technology need may map to multiple TABS technology

    Intrinsic toroidal rotation in a tokamak can be driven by turbulent momentum transport due to neoclassical flow effects breaking a symmetry of turbulence. In this paper we categorize the contributions due to neoclassical effects to the turbulent momentum transport, and evaluate each contribution using gyrokinetic simulations. We find that the relative importance of each contribution changes with collisionality. For low collisionality, the dominant contributions come from neoclassical particle and parallel flows. For moderate collisionality, there are non-negligible contributions due to neoclassical poloidal electric field and poloidal gradients of density and temperature, which are not important for low collisionality.

    Cancer is a leading cause of widowed fatherhood in the USA. Fathers whose spouses have died from cancer constitute a potentially vulnerable population as they adjust to their role as sole or primary caregiver while managing their own grief and that of their children. The importance of addressing the psychological needs of widowed fathers is underscored by data showing that father's coping and emotional availability are closely tied to their bereaved children's mental health. Surprisingly, scant attention has been given to the phenomenon of widowed fatherhood with virtually no clinical resources or research studies devoted to fathers who have lost their wives to cancer. This commentary highlights key challenges facing this underserved population of widowers and calls for development of research agendas and clinical interventions for single fathers due to cancer.

    The role of policy instruments to promote the development and diffusion of energy efficient technologies has been repeatedly accentuated in the context of climate change and sustainable development. To better understand the impact of policy instruments and to provide insights into technology change, assessments of various kinds are needed. This study analyzes the introduction and development of energy efficient windows in Sweden and the policy incentives applied to support this process. The study focuses on the assessment of technology and market development of energy efficient windows in Sweden; and by applying the concept of learning, it assesses how conditions for learning-by-searching, learning-by-doing, learning-by-using and learning-by-interacting have been supported by different policies. The results show successful progress in technology development and an improvement in best available technology of Swedish windows from 1.8 W/m 2 K in the 1970s to 0.7 W/m 2 K in 2010; in the same time period the market share of energy efficient windows increased from 20% in 1970 (average U-value of 2.0 W/m 2 K) to 80-85% in 2010 (average U-value of 1.3-1.2 W/m 2 K). The assessment shows that various policy instruments have facilitated all four learning processes resulting in the acknowledged slow but successful development of energy efficient windows. - Highlights: → Policy instruments for learning and technology change are assessed. → The development and diffusion of energy efficient windows (EEWs) in Sweden is taken as showcase. → Learning has been supported by various policies resulting in successful development of EEWs. → The thermal performance of EEWs improved with 2/3 and their market share increased by 3/5 in 40 years. → Main policies for learning are RD and D, technology procurement, testing and voluntary initiatives.

    Researches are conducted on the creation of sub-millimeter structured coatings for engine cylinders, valve seats, etc., for the extensive enhancement of performance of tribology-involved parts. In relation to the technology of high-energy pulse laser-aided fabrication of coatings, a coating manufacturing unit is designed and built, and experiments are conducted for the improvement of molten particle generation efficiency and for the formation of coatings by the adhesion of molten Fe and Mo particles onto a cast iron substrate. In the study of abrasion-proof internal surface treatment technology, various sprayed coatings are prepared and checked for the surface reforming effect of laser irradiation, which is for the identification of sprayed coatings which are fit for laser-aided composite surface treatment. In the study of the creation of self-heat generative compounds and the practical application of their bonding feature, the effect is examined of laser irradiation conditions on the hardness and other properties of the surface layer of a hot-pressed Fe{sub 3}Al body with its surface coarseness homogenized by machining. For the analysis of the mechanism of tribological characteristics, coatings are caused to rub against each other in engine oil. (NEDO)

  2. Nanoscale hotspots due to nonequilibrium thermal transport

    2004-01-01

    Recent experimental and modeling efforts have been directed towards the issue of temperature localization and hotspot formation in the vicinity of nanoscale heat generating devices. The nonequilibrium transport conditions which develop around these nanoscale devices results in elevated temperatures near the heat source which can not be predicted by continuum diffusion theory. Efforts to determine the severity of this temperature localization phenomena in silicon devices near and above room temperature are of technological importance to the development of microelectronics and other nanotechnologies. In this work, we have developed a new modeling tool in order to explore the magnitude of the additional thermal resistance which forms around nanoscale hotspots from temperatures of 100-1000K. The models are based on a two fluid approximation in which thermal energy is transferred between ''stationary'' optical phonons and fast propagating acoustic phonon modes. The results of the model have shown excellent agreement with experimental results of localized hotspots in silicon at lower temperatures. The model predicts that the effect of added thermal resistance due to the nonequilibrium phonon distribution is greatest at lower temperatures, but is maintained out to temperatures of 1000K. The resistance predicted by the numerical code can be easily integrated with continuum models in order to predict the temperature distribution around nanoscale heat sources with improved accuracy. Additional research efforts also focused on the measurements of the thermal resistance of silicon thin films at higher temperatures, with a focus on polycrystalline silicon. This work was intended to provide much needed experimental data on the thermal transport properties for micro and nanoscale devices built with this material. Initial experiments have shown that the exposure of polycrystalline silicon to high temperatures may induce recrystallization and radically increase the thermal

    This paper analyzes potentials of carbon capture and sequestration technologies (CCT) in a set of long-term energy-economic-environmental scenarios based on alternative assumptions for technological progress of CCT. In order to get a reasonable guide to future technological progress in managing CO 2 emissions, we review past experience in controlling sulfur dioxide (SO 2 ) emissions from power plants. By doing so, we quantify a 'learning curve' for CCT, which describes the relationship between the improvement of costs due to accumulation of experience in CCT construction. We incorporate the learning curve into the energy-modeling framework MESSAGE-MACRO and develop greenhouse gas emissions scenarios of economic, demographic, and energy demand development, where alternative policy cases lead to the stabilization of atmospheric CO 2 concentrations at 550 parts per million by volume (ppmv) by the end of the 21st century. We quantify three types of contributors to the carbon emissions mitigation: (1) demand reductions due to the increased price of energy, (2) fuel switching primarily away from coal, and (3) carbon capture and sequestration from fossil fuels. Due to the assumed technological learning, costs of the emissions reduction for CCT drop rapidly and in parallel with the massive introduction of CCT on the global scale. Compared to scenarios based on static cost assumptions for CCT, the contribution of carbon sequestration is about 50% higher in the case of learning, resulting in cumulative sequestration of CO 2 ranging from 150 to 250 billion (10 9 ) tons with carbon during the 21st century. Also, carbon values (tax) across scenarios (to meet the 550 ppmv carbon concentration constraint) are between 2% and 10% lower in the case of learning for CCT by 2100. The results illustrate that assumptions on technological change are a critical determinant of future characteristics of the energy system, indicating the importance of long-term technology policies in

    2010-05-15

    In life sciences, interpretability of machine learning models is as important as their prediction accuracy. Linear models are probably the most frequently used methods for assessing feature relevance, despite their relative inflexibility. However, in the past years effective estimators of feature relevance have been derived for highly complex or non-parametric models such as support vector machines and RandomForest (RF) models. Recently, it has been observed that RF models are biased in such a way that categorical variables with a large number of categories are preferred. In this work, we introduce a heuristic for normalizing feature importance measures that can correct the feature importance bias. The method is based on repeated permutations of the outcome vector for estimating the distribution of measured importance for each variable in a non-informative setting. The P-value of the observed importance provides a corrected measure of feature importance. We apply our method to simulated data and demonstrate that (i) non-informative predictors do not receive significant P-values, (ii) informative variables can successfully be recovered among non-informative variables and (iii) P-values computed with permutation importance (PIMP) are very helpful for deciding the significance of variables, and therefore improve model interpretability. Furthermore, PIMP was used to correct RF-based importance measures for two real-world case studies. We propose an improved RF model that uses the significant variables with respect to the PIMP measure and show that its prediction accuracy is superior to that of other existing models. R code for the method presented in this article is available at http://www.mpi-inf.mpg.de/ approximately altmann/download/PIMP.R CONTACT: altmann@mpi-inf.mpg.de, laura.tolosi@mpi-inf.mpg.de Supplementary data are available at Bioinformatics online.

In the designing and evaluation for a strongest Nb-base composite material, Nb-base composite materials are manufactured by use of particle dispersion-strengthening attained by addition of intermetallic compounds or elements to contribute to the formation of oxides, carbides, or nitrides. Nb-base composite materials may also be manufactured by use of eutectic-strengthening attained by utilizing crystallization in the process of coagulation. The resultant Nb-base composite materials are evaluated for their dynamic characteristics at high temperatures. In the development and evaluation of technologies for creating Nb-base materials for high-temperature components, larger specimens as heavy as several kg are tested in line with small specimens for basic studies, and the results are utilized for alloy designing for high-temperature materials. 50 refs., 97 figs., 15 tabs.

This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

    Two children were admitted to a medical centre due to dehydration after an oral injury and the extraction of a tooth. One child complained of "mouth broken". Dehydration is the most common water-electrolyte imbalance in children. Babies and young children are prone to dehydration due to their relatively large body surface area, the high percentage extracellular fluid, and the limited ability of the kidneys to conserve water. After the removal ofa tooth, after an oral trauma or in case of oral discomfort, a child is at greater risk of dehydration by reduced fluid and food intake due to oral pain and/or discomfort and anxiety to drink. In those cases, extra attention needs to be devoted to the intake of fluids.

    Full Text Available Antibiotic residues are the most present inhibitory substances in milkhaving undesirable effect on human health, technological characteristics and the quality of milk and dairy products. In order to protect consumer's health and to ensure high quality milk production, European Union (EU regulation 2377/90 sets a maximum permitted levels for antibiotic residues in milk. Although the presence of antibiotic residues in milk can be due to animal diseases treatment, and in the case of milking animals, they are mostly present after mastitis treatment. The aim of this work is to stress the importance of the continuous control on antibiotic residues presence in milk, due to the role that milk and dairy products have in human nutrition. In this paper, different groups of antibiotics, mechanisms of theirs action, mistakes occurring in dairy products manufacture as well as the methods for theirs detection are described.

    While computing is applied widely in the production segment of the petroleum industry, its effective application is the primary goal of computing management. Computing technology has changed significantly since the 1950's, when computers first began to influence petroleum technology. The ability to accomplish traditional tasks faster and more economically probably is the most important effect that computing has had on the industry. While speed and lower cost are important, are they enough? Can computing change the basic functions of the industry? When new computing technology is introduced improperly, it can clash with traditional petroleum technology. This paper examines the role of management in merging these technologies

    The objective of this summer's work was to attempt to enhance Technology Application Group (TAG) ability to measure the outcomes of its efforts to transfer NASA technology. By reviewing existing literature, by explaining the economic principles involved in evaluating the economic impact of technology transfer, and by investigating the LaRC processes our William & Mary team has been able to lead this important discussion. In reviewing the existing literature, we identified many of the metrics that are currently being used in the area of technology transfer. Learning about the LaRC technology transfer processes and the metrics currently used to track the transfer process enabled us to compare other R&D facilities to LaRC. We discuss and diagram impacts of technology transfer in the short run and the long run. Significantly, it serves as the basis for analysis and provides guidance in thinking about what the measurement objectives ought to be. By focusing on the SBIR Program, valuable information regarding the strengths and weaknesses of this LaRC program are to be gained. A survey was developed to ask probing questions regarding SBIR contractors' experience with the program. Specifically we are interested in finding out whether the SBIR Program is accomplishing its mission, if the SBIR companies are providing the needed innovations specified by NASA and to what extent those innovations have led to commercial success. We also developed a survey to ask COTR's, who are NASA employees acting as technical advisors to the SBIR contractors, the same type of questions, evaluating the successes and problems with the SBIR Program as they see it. This survey was developed to be implemented interactively on computer. It is our hope that the statistical and econometric studies that can be done on the data collected from all of these sources will provide insight regarding the direction to take in developing systematic evaluations of programs like the SBIR Program so that they can

    2014-09-01

    Technology alone will not be able to solve adaptation challenges, but it is likely to play an important role. As a result of the role of technology in adaptation and the importance of international collaboration for climate change, technology transfer for adaptation is a critical but understudied issue. Through an analysis of Global Environment Facility-managed adaptation projects, we find there is significantly more technology transfer occurring in adaptation projects than might be expected given the pessimistic rhetoric surrounding technology transfer for adaptation. Most projects focused on demonstration and early deployment/niche formation for existing technologies rather than earlier stages of innovation, which is understandable considering the pilot nature of the projects. Key challenges for the transfer process, including technology selection and appropriateness under climate change, markets and access to technology, and diffusion strategies are discussed in more detail.

  8. Uses of risk importance measures

    Mankamo, T.; Poern, K.; Holmberg, J.

    1991-05-01

    Risk importance measures provide an understandable and practical way of presenting probabilistic safety analysis results which too often tend to remain abstract numbers without real insight into the content. The report clarifies the definitions, relationships and interpretations of the three most basic measures: Risk increase factor, risk decrease factor, and fractional contribution. The above three measures already cover the main types of risk importance measures. Many other importance measures presented in literature are close variants to some of these three measures. They are related in many cases so that, for a technical system considered, the two other measures can be derived from the one calculated first. However, the practical interpretations are different, and hence each three measures have their own uses and rights to existence. The fundamental aspect of importance measures is, that they express some specific influence of a basic event on the total risk. The basic failure or error events are the elements from which the reliability and risk models are constituted. The importance measures are relative, which is an advantage compared to absolute risk numbers, due to insensitivity with respect to quantification uncertainties. Therefore they are particularly adapted to give first hand guidance where to focus main interest from the system's risk and reliability point of view and wherefrom to continue the analysis with more sophisticated methods requiring more effort

    The aim of the investigation is to define as clearly as possible specific forensic psychiatric characteristics of persons who committed homicide and or attempted due to jealousy (the nature and severity of psychopathology, the level of responsibility, danger for the community, intensity and nature of aggression, the victimologic dimension, the relation of alcohol and jealousy). A retrospective method based on forensic psychiatric expertises in the period 1975-1999 was used. They encompassed 200 examinees that committed murder or attempted it. The results show the connection of psychotic jealousy with the highest degree of danger in diagnostic categories of paranoid psychosis and paranoid schizophrenia. The time span from the first manifestations of jealousy until the actual commitment of a crime is the longest in personality disorders and the shortest in schizophrenia. Exogenous provoking situations were dominant for committing homicide due to jealousy in personality disorders. Acute alcohol intoxication has a specific significance in crime due to jealousy in the same diagnostic category. Clear criteria were designed for forensic psychiatric evaluation of murder and attempts of homicide caused by jealousy, which will be of help in everyday practice in the field forensic work and treatment.

The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components.

    Full Text Available The article discusses current state of Russian electric power industry and the main problems of its development in the future of global energy revolution, which will lead to a significant increase in share of renewable energy in global production and consumption of energy and use of industrial energy storage, and will make it possible to change the structure of the industry and significantly reduce electricity prices. Traditional energy generation displacement by renewables associated with emergence of new, more cost effective technologies. Producers of “disruptive technologies” receive advantages over importers of innovations, which are especially noticeable during the formation of the new technological wave. Considering possibilities of effective development of Russian power industry, it is important to take into account the realities, including high level of depreciation of equipment, lack of capital and technologies. Currently, in the field of technology in the power industry innovative economies of Japan, USA, UK, Canada, as well as dynamically developing economy of China are leading. The high level of patent activity in these countries is caused by presence of infrastructure which promotes the commercialization of new technologies and free access to investment capital. In Russia technological exports in power sector occurs mainly due to foreign projects of Rosatom. Operation of foreign-made equipment which accounts for a significant proportion of fixed assets and problems with the development and introduction of competitive technologies are complicated by the lack of investment in domestic market. For maintenance of imported equipment Russian companies have to buy spare parts abroad and to enter into service contracts with foreign suppliers. High depreciation of fixed assets also determines the need for new investment inflows into the sector. Thus the existing dependence on foreign investors is supposed to increase. In the short term

Potassium has three isotopes {sup 39}K, {sup 40}K and {sup 41}K, two are stable while {sup 40}K is radioactive with a half life of 1.2x10{sup 9} years; there is 0.0117% {sup 40}K-to-K ratio. Potassium plays an important role in plants, animals and humans growth and reproduction. Due to the fact that K is an essential element for humans, {sup 40}K is the most abundant radioisotope in human body. In order to keep good health conditions K must be intake at daily basis trough food and beverages, however when K in ingested above the requirements produce adverse health effects in persons with renal, cardiac and hypertension problems or suffering diabetes. In 89.3% {sup 40}K decays to {sup 40}C through {beta}-decay, in 10.3% decays through electronic capture and emitting 1.46 MeV {gamma}-ray. K is abundant in soil, construction materials, sand thus {gamma}-rays produced during {sup 40}K decay contribute to external dose. For K in the body practically all {sup 40}K decaying energy is absorbed by the body; thus {sup 40}K contributes to total dose in humans and it is important to evaluate its contribution. In this work a set of {sup 40}K sources were prepared using different amounts of KCl salt, a {gamma}-ray spectrometer with a NaI(Tl) was characterized to standardized the sources in order to evaluate the dose due to {sup 40}K. Using thermoluminescent dosemeters the dose due to {sup 40}K was measured and related to the amount of {sup 40}K {gamma}-ray activity. (Author)

  15. User-centric technology design for nonprofit and civic engagements

    2014-01-01

    Due to the increased global political importance of the nonprofit sector, its technological support and organizational characteristics have become important fields of research. In order to conduct effective work, nonprofits need to communicate and coordinate effectively. However, such settings are generally characterized by a lack of resources, an absence of formal hierarchical structures and differences in languages and culture among the activists. Modern technologies could help nonprofit networks in improving their working. In order to design appropriate technological support for such settings, it is important to understand their work practices, which widely differ from traditional business organizations. This book aims to strengthen the body of knowledge by providing user studies and concepts related to user centered technology design process for nonprofit settings. The examination of ethnographic studies and user centered evaluation of IT artifacts in practice will further the understanding of design requ...

    The goal is to develop basic technologies to build an SiC device capable of service amid high-temperature surroundings for the advancement and optimization of combustion control systems. In an SiC semiconductor, the Si-C bond is broken when irradiated with ions, and this makes the occurrence of thermal oxidation easy to occur. In the study to form SiC into single-crystal substrates, a substrate with warpage of 10 micrometers or less and surface coarseness of 10 nanometers or less is realized. In the development of sensor technologies, the high-speed CVD (chemical vapor deposition) method is applied for the growth of crystals further on a 3C-SiC layer epitaxially grown by MBE (molecular beam epitaxy) surface control, which improves on layer characteristics. Element technologies are developed for the construction of a 3-terminal element (FET: field effect transistor), which is for the construction of a high-temperature, high-speed SiC device. An effort is made at achieving 3C-SiC hetero-epitaxial growth, etc., on a 3-inch Si substrate using an SiC crystal film formation experimenting apparatus, which aims at constructing a control device. Concerning the combustion control system, the relations between the air/fuel ratio and the emission spectra of radicals OH, CH, and C2 in a flame are made clear. Also referred to are the basic studies being conducted at research institutes such as universities and a survey of technological trends abroad.

  17. DYSTOCIA DUE TO SOFT TISSUE

    DeCarle, Donald W.

    1954-01-01

    In dystocia caused by abnormal conditions of the soft parts, the etiologic changes may be either in the genital tissues or in adjacent soft structures. Broadly, the conditions causing the difficulty may be grouped as follows: (1) anomalies or congenital modifications; (2) tumors; (3) modifications due to age, accident or surgical operations; (4) modification of the expulsive forces; (5) abnormalities of the products of conception. Often in such circumstances cesarean section is necessary. Sometimes when tumor is present it can be removed before it interferes with delivery, but decision to excise the growth must be guided by such factors as the location of the lesion and the stage of gestation. This would determine to what extent the maintenance of pregnancy would be jeopardized by surgical intervention before term. PMID:13190430

    Each year in the United States, an estimated 800 to 1,400 people are murdered at work, and an unknown number of nonfatal injuries due to workplace violence occur. Based on Ohio's workers' compensation claims from 1983 through 1985, police officers, gasoline service station employees, employees of the real estate industry, and hotel/motel employees were found to be at the highest risk for occupational violent crime (OVC) injury and death. Grocery store employees, specifically those working in convenience food stores, and employees of the real estate industry had the most reported rapes. Four previously unidentified industries at increased risk of employee victimization were described. Identification of industries and occupations at high risk for crime victimization provides the opportunity to focus preventive strategies to promote employee safety and security in the workplace.

    In recent years, there has been an increase in cases of imported helminthiasis in Spain because of two complementary causes: immigration and international travel. Although the prevalence of helminthiasis is high in the immigrant population, the risk of transmission to the Spanish population is low. In this review, we provide clues to aid in the diagnosis of the helminthiasis, highlighting the geographic characteristics, clinical findings and analytical results of the most frequent types. The low sensitivity of the classic parasitological diagnostic test, mainly in tissue helminthiasis, is described. In addition, the advantages and limitations of the common serological methods for detecting related circulating antigens and antibodies are presented. Certain molecular methods used in the diagnosis of imported helminthiasis and the best strategies for screening of this condition are discussed.

  20. Human spaceflight technology needs-a foundation for JSC's technology strategy

    Science.gov (United States)

    Stecklein, J. M.

    Human space exploration has always been heavily influenced by goals to achieve a specific mission on a specific schedule. This approach drove rapid technology development, the rapidity of which added risks and became a major driver for costs and cost uncertainty. The National Aeronautics and Space Administration (NASA) is now approaching the extension of human presence throughout the solar system by balancing a proactive yet less schedule-driven development of technology with opportunistic scheduling of missions as the needed technologies are realized. This approach should provide cost effective, low risk technology development that will enable efficient and effective manned spaceflight missions. As a first step, the NASA Human Spaceflight Architecture Team (HAT) has identified a suite of critical technologies needed to support future manned missions across a range of destinations, including in cis-lunar space, near earth asteroid visits, lunar exploration, Mars moons, and Mars exploration. The challenge now is to develop a strategy and plan for technology development that efficiently enables these missions over a reasonable time period, without increasing technology development costs unnecessarily due to schedule pressure, and subsequently mitigating development and mission risks. NASA's Johnson Space Center (JSC), as the nation's primary center for human exploration, is addressing this challenge through an innovative approach in allocating Internal Research and Development funding to projects. The HAT Technology Needs (Tech Needs) Database has been developed to correlate across critical technologies and the NASA Office of Chief Technologist Technology Area Breakdown Structure (TABS). The TechNeeds Database illuminates that many critical technologies may support a single technical capability gap, that many HAT technology needs may map to a single TABS technology discipline, and that a single HAT technology need may map to multiple TABS technology disciplines.

  2. Strategic materials: Technologies to reduce US import vulnerability

    Science.gov (United States)

    1985-05-01

    Three nations, South Africa, Zaire, and the U.S.S.R., account for over half of the world's production of chromium, cobalt, manganese, and platinum group metals. These metals are essential in the production of high-temperature alloys, steel and stainless steel, industrial and automotive catalysts, electronics, and other applications that are critical to the U.S. economy and the national defense. With minor exceptions, there is no domestic mine production of any of the four metals. Government actions to assure secure supplies of metals critical to the United States have been limited largely to reliance on the national defense stockpile to ensure the availability of materials required for national defense in time of war, leaving it to the free market to provide a diversity of suppliers for the industrial economy. An overall strategy to reduce U.S. reliance on uncertain sources of supply of strategic materials should be based on a combination of three technical approaches: increase the diversity of the world supply of strategic metals through the development of promising deposits; decrease demand for strategic metals through the implementation of improved manufacturing processes and recycling of strategic materials from scrap and waste; and identify and test substitute materials for current applications and develop new materials with reduced strategic material content for future applications.

    The theme of the International Biohydrometallurgy Symposium held in Jackson Hole, Wyoming, August 22-25, 1993, is ''Biohydrometallurgy: An Industry Matures.'' This is a developing technology which made important contributions to the minerals industry. Biohydrometallurgical technology was first introduced into the copper industry and subsequently to the uranium industry for the production of metal values from low-grade mineral resources. Currently, biotechnology has advanced a step further. It is now commercially applied for the treatment of high-grade refractory gold ores in aerated stirred reactors to liberate precious metals for cyanidation. In addition, the industrial applications of biotechnology involve bioenhanced tertiary oil recovery processes, which contribute to an increase in oil production from previously exhausted wells. Furthermore, many bioremediation technologies are being developed for the removal of toxic heavy metals and radionuclides from contaminated soils and aqueous mining and industrial effluents. This volume contains papers selected for publication which are predominantly dealing with subjects related to laboratory and industrial scale bioleaching of base and precious metals, biocorrosion phenomena, diverse bioreduction processes and electrochemical reactions. Individual papers have been processed separately for inclusion in the appropriate data bases

    Hemorrhagic fever with renal syndrome (HFRS) is due to an infection by the virus of the Hantavirus genus. Rodent hosts of Hantavirus are present in restricted areas in France; consequently, there are ecological niches and microepidemics of human Hantavirus infections. A HFRS case was diagnosed in the Paris region. The 11-year-old child had an acute debut fever-persistent despite antipyretic medication-asthenia, headache, abdominal pain, myalgia, thrombocytopenia, as well as renal failure with proteinuria. The diagnosis was made with a relevant clinical history and the specific serology of Puumala hantavirus. Therefore, a kidney biopsy was not necessary. What was interesting was the diagnostic approach because of the difference between the place and time of contamination and where the child became ill and developed the symptoms. The child was infected by Puumala hantavirus in Les Ardennes, a high-risk area, but became ill in the Paris region, an area with no prevalence. We review Hantavirus infections in France and its differential diagnosis. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Risk Communication has shown its importance in the elaboration of emergency plans in the Chemical industry. In the 90's, the UNEP developed the APELL (Awareness and Preparedness for Emergency at Local Level) plan, a risk management methodology used by dangerous chemical facilities. The methodology comprises the commitment of both Government and the community located in the risk area in the development of the emergency plan. In the nuclear sector, there is no similar methodology developed so far. However, establishing a communication channel between the nuclear segment and the community is essential. In Brazil, the construction of Angra 3 and the RMB (Multi Purpose Reactor) project stand as nuclear initiatives that improve the importance of a good communication to the public. Security issues of these projects are natural sources of concernment to the public, which is aggravated by events such as the Fukushima disaster. Without an effective communication about what means the presence of nuclear plants and reactors in a specific area, the interested public will only have an alarmist vision of the subject, given by those against these facilities.

    Organising pneumonia is one of the responses of the lung to injury and can mimic bacterial pneumonia but importantly it does not respond to antibiotic therapy. We present the case of a 67-year-old male who was diagnosed with organising pneumonia secondary to dronedarone. Drug reactions are a common cause and early identification of the culprit is mandatory to prevent further morbidity and ensure a favourable outcome. On chest radiography there may be fleeting peripheral consolidation, while computed tomography can show a range of stereotyped patterns including perilobular consolidation. Bronchoscopic biopsy may not always be possible but response to steroids is often rapid following removal of the culprit drug. Dronedarone should be included in the list of possible drugs and the Pneumotox database remains a useful resource for the clinician when acute drug-related pneumotoxicity is suspected.

  11. Emerging environmental technologies and environmental technology policy

    Science.gov (United States)

    Clarke, Leon Edward

    This dissertation explores the role and design of environmental technology policy when environmental innovation is embodied in emerging environmental technologies such as photovoltaic cells or fuel cells. The dissertation consists of three individual studies, all of which use a simplified, general model industry between an emerging environmental technology and an entrenched, more-polluting technology. It clarifies the situations in which environmental technology policy can achieve high welfare and those in which it cannot; and it separates the possible situations an emerging environmental technology might face into four scenarios, each with its own technology policy recommendations. The second study attempts to clarify which of two factors is having a larger limiting effect on private investment in photovoltaics: the failure to internalize the environmental costs of fossil fuel electricity generation or a broad set of innovation market failures that apply to innovation irrespective of environmental concerns. The study indicates that innovation market failures are probably having a significantly larger impact than incomplete internalization. The third study explores the effectiveness of adoption subsidies at encouraging private-sector innovation. The conclusion is that adoption subsidies probably have only a limited effect on long-term, private-sector research. Two important general conclusions of the dissertation are (1) that optimal technology policy should begin with technology-push measures and end with demand-pull measures; and (2) that the technological response to internalization instruments, such as emissions taxes, may be highly nonlinear.

  12. Important aspects of midwifery

    Directory of Open Access Journals (Sweden)

    E. Barnett

    1980-09-01

    Full Text Available The art of midwifery must be one of the oldest of acquired skills. In prehistoric times, the more experienced women assisted and comforted their younger relatives during parturition. There are scattered references to midwives in ancient literature, including the Bible. In Genesis 35:17 we learn that Rachel’s death was the result of “ hard labour” . One should congratulate the midwife who delivered Sarah of a son at the age of 90 years - Genesis 17:17. Midwifery stagnated during the Middle Ages due, partly to the ignorance of the midwives as well as to a lack of knowledge of human anatomy coupled with the accepted teaching of the ancients, which was regarded as the ultimate authority. Great advances in the art and science of midwifery have occurred since the Middle Ages, amounting to a revolution in thought and practice. Less than 100 years ago, in 1898, in W.S. Playfair’s “Science and Practice of Midwifery” no mention was made of any form of antenatal examination or even of the testing of urine for albumin. Times have indeed changed - today the whole concept of maternal and child care would be quite unrecognisable to a Victorian midwife. We have also accepted the male midwife into our midst.

    Aluminoses are widespread forms of trace element deficiency of various severity. The organism is protected against a possible pathogenic influence of aluminum by a number of physiological mechanisms the most important among which is a regular urine excretion. A complex of pathological symptoms develops if serious homeostasis disturbances take place e. g. when renal deficiency or direct penetration of the trace element occur. The following forms of aluminosis should be distinguished: 1) simple accumulation in central nervous system which occurs in persons over 65 years; 2) aluminum accumulation in Alzheimer disease, in severe form of presenile and senile dementia; 3) dialysis aluminum encephalopathy; 4) non-dialysis infantile encephalopathy; 5) aluminum encephalopathy in total parenteral nutrition; 6) iatrogenic dialysis aluminum osteodystrophy; 7) jatrogenic peritoneal aluminosis; 8) aluminum pneumoconiosis of an occupational origin; 9) bronchospastic syndrome in aluminum smelter workers.

    2002-01-01

    This presentation provides an overview of Mexico's energy sector. Proven oil reserves place Mexico in ninth position in the world and fourth largest in natural gas reserves. Energy is one of the most important economic activities of the country, representing 3 per cent of Gross Domestic Product (GDP). Oil exports represent 8.4 per cent of total exports. Approximately 40 per cent of total public investment is earmarked for energy projects. The author discusses energy resources and energy sector limitations. The energy sector plan for the period 2001-2006 is discussed. Its goals are to ensure energy supply, to develop the energy sector, to stimulate participation of Mexican enterprises, to promote renewable energy sources, and to strengthen international energy cooperation. The regulatory framework is being adapted to increase private investment. Some graphs are presented, displaying the primary energy production and primary energy consumption. Energy sector reforms are reviewed, as are electricity and natural gas reforms. The energy sector demand for 2000-2010 and investment requirements are reviewed, as well as fuel consumption for power generation. The author discusses the National Pipeline System (SNG) and the bottlenecks caused by pressure efficiency in the northeast, flow restriction on several pipeline segments, variability of the Petroleos Mexicanos (PEMEX) own use, and pressure drop on central regions. The entire prospect for natural gas in the country is reviewed, along with the Strategic Gas Program (PEG) consisting of 20 projects, including 4 non-associated natural gas, 9 exploration and 7 optimization. A section dealing with multiple service contracts is included in the presentation. The authors conclude by stating that the priority is a national energy policy to address Mexico's energy security requirements, to increase natural gas production while promoting the diversification of imports, and a regulatory framework to be updated in light of current

    To improve the standard of society's quality of life, it is necessary to improve the quality of distributed energy and its inherent services within a sustainability process. Among different technological routes that produce more sustainable energy are the fuel cells - also known as combustible batteries. The Global Environment Facility (GEF) has identified the fuel cells as a potential technology to reduce, in the future, the effect of greenhouse gases in both developed and developing countries. Although there are various types of fuel cells, the most used technology for research studies on fuel cells is the Polymer Electrolyte Fuel Cells (FEMFC). However, economic issues - related to the high cost of the membrane's materials and of the catalysts of groups of platinum metals - are still some of the obstacles that need to be overcome for this technology to be more accessible. There are also socio-environmental aspects related to the impacts caused by the extraction, the use and the destination of these metals. Taking in consideration the challenges of complying with the demands of the market and the society as well as with the growing tendency of more rigid patterns of environmental control, the objective of the present work is to show the tool of environmental management - Life Cycle Assessment (LCA) - and its importance on the pursuit for socio-economic and environmental alternatives feasible to the recycling of the catalysts of platinum of the PEMFC. This way, it intends to collaborate to the progress of the knowledge about environmental and socio-economic subjects related to the productive process of the PEMFC. (author)

    2012-02-01

    Full Text Available The effective management of technology as a source of competitive advantage is of vital importance for many organizations. It is necessary to understand, communicate and integrate technology strategy with marketing, financial, operations and human resource strategies. This is of particular importance when one considers the increasing cost, pace and complexity of technology developments, combined with shortening product life cycles. A five process model provides a framework within which technology management activities can be understood: identification, selection, acquisition, exploitation and protection. Based on this model, a technology management assessment procedure has been developed, using an ``action research’’ approach. This paper presents an industrial case study describing the first full application of the procedure within a high-volume manufacturing business. The impact of applying the procedure is assessed in terms of benefits to the participating business, together with improvements to the assessment procedure itself, in the context of the action research framework.

    2006-01-01

    Thirteen sheep from a milk producing farm in the Canton of Grisons that presented chronic coenurosis were examined and subjected to treatment trials at the veterinary hospital in Zurich. Symptoms were first observed around two months after the import of two dogs from Italy (Abruzza) of which one was infected with Taenia multiceps and Echinococcus granulosus. The most frequently observed clinical symptoms of the sheep were reduced general condition, circling, reduced menace reflex, apathy, unsteady gait and head tilt. Analyses of cerebrospinal fluid revealed an increased leucocyte count in 3 sheep and eosinophilia in 4 sheep. In 4 animals that underwent computertomography, one or more hypodense, definable lesions were found in the brain. In 2 sheep surgical treatment and in 10 animals medical treatment with either Praziquantel (n=8) or Oxfendazol (n=2) was attempted. Only one animal treated with Praziquantel needed not to be euthanized. At necropsy, one or two coenurus cysts could be found either in a side ventricle (n=2), in the cerebellum (n=3) or in the cerebrum (n=7). The locations corresponded with the clinical findings. Despite Praziquantel or Oxfendazol treatment, living protoscoleces could be found in the parasite cysts [de

    On April 26, 1986, explosion occurred in Chernobyl nuclear power station in USSR, and radioactivity contamination was brought about in almost all countries in the world. In European countries, crops were contaminated directly with radioactive fallout to high concentration. Also in Japan, after one week the radioactivity higher than usual was detected in environment, and also in vegetables, milk, tea leaves and others. Thereafter, in order to cope with the import of contaminated foods, inspection and watch system was strengthened by deciding the interim limit of radioactive concentration. However the cases of exceeding the interim limit were often reported. In order to remove the harmful foods due to radioactive contamination and to meet the fear of consumers, the authors measured the radioactive concentration in foods distributed in Tokyo and investigated the actual state of contamination. The samples were 920 imported foods. The experimental method, the preparation of samples, the method of analysis and the results are reported. The samples in which the radioactive concentration exceeding 50 Bq/kg was detected were 25 cases. The food having the high frequency of detection was flavors. (K.I.)

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

    Economic importance of environmental issues is increasing, and new technologies are expected to reduce pollution derived both from productive processes and products, with costs that are still unknown. Until now there is still little knowledge concerning the process of technological innovation in this field. What does exist, is outdated due to rapid change in technology. In this paper we analyse the development of Zinc Air Fuel Cells (ZAFC) and their transfer from research laboratories to large mass production. ZAFC are a new environmental technology, proved to have a commercial value, that can be used for building Zero Emission Vehicles (ZEV). Although ZAFC performances are higher than traditional lead-acid batteries ones, difficulties in funding ZAFC engineering and moving them from laboratories to production caused some years delay in their diffusion. On the bases of this paradigmatic case, we argue that existing economic and organizational literature concerning technological innovation is not able to fully explain steps followed in developing environmental technologies. Existing models mainly consider adoption problems as due to market uncertainty, weak appropriability regime, lack of a dominant design, and difficulties in reconfiguring organizational routines. Additionally, the following aspects play a fundamental role in developing environmental technologies, pointing out how technological trajectories depend both on exogenous market conditions and endogenous firm competencies: 1 regulations concerning introduction of ZEV create market demand and business development for new technologies; they impose constraints that can be met only by segmenting transportation market at each stage of technology development; 2 each stage of technology development requires alternative forms of division and coordination of innovative labour; upstream and downstream industries are involved in new forms of inter-firm relationships, causing a reconfiguration of product architecture

    The most important applications of the radiation technology are the crosslinking of polymers and sterilisation. Although extensive experience about the use of this technology is available and powerful and dependable radiation facilities can be obtained, as yet the radiation technology has not found the acceptance it deserves in the industry. The main reason therefore has to do with how the question of radiation or the term radiation is presented to the industry and among the population. This paper will deal with considerations and ways in which the industrial use of the radiation technology can be expanded. (author)

    Since 2006 NASA has been formulating robotic missions to the lunar surface through programs and projects like the Robotic Lunar Exploration Program, Lunar Precursor Robotic Program, and International Lunar Network. All of these were led by NASA Marshall Space Flight Center (MSFC). Due to funding shortfalls, the lunar missions associated with these efforts, the designs, were not completed. From 2010 to 2013, the Robotic Lunar Lander Development Activity was funded by the Science Mission Directorate (SMD) to develop technologies that would enable and enhance robotic lunar surface missions at lower costs. In 2013, a requirements-driven, low-cost robotic lunar lander concept was developed for the Resource Prospector Mission. Beginning in 2014, The Advanced Exploration Systems funded the lander team and established the MSFC, Johnson Space Center, Applied Physics Laboratory, and the Jet Propulsion Laboratory team with MSFC leading the project. The lander concept to place a 300-kg rover on the lunar surface has been described in the New Technology Report Case Number MFS-33238-1. A low-cost lander concept for placing a robotic payload on the lunar surface is shown in figures 1 and 2. The NASA lander team has developed several lander concepts using common hardware and software to allow the lander to be configured for a specific mission need. In addition, the team began to transition lander expertise to United States (U.S.) industry to encourage the commercialization of space, specifically the lunar surface. The Lunar Cargo Transportation and Landing by Soft Touchdown (CATALYST) initiative was started and the NASA lander team listed above is partnering with three competitively selected U.S. companies (Astrobotic, Masten Space Systems, and Moon Express) to develop, test, and operate their lunar landers.

    In this paper, we propose a new methodology of identifying important research problems to be solved to improve the performance of some specific scientific technologies by the phenomena identification and ranking table (PIRT) process which has been used as a methodology for demonstrating the validity of the best estimate simulation codes in US Nuclear Regulatory Commission (USNRC) licensing of nuclear power plants. The new methodology makes it possible to identify important factors affecting the performance of the technologies from the viewpoint of the figure of merit and problems associated with them while it keeps the fundamental concepts of the original PIRT process. Also in this paper, we demonstrate the effectiveness of the new methodology by applying it to a task of extracting research problems for improving an inspection accuracy of ultrasonic testing or eddy current testing in the inspection of objects having cracks due to fatigue or stress corrosion cracking.

    1997-12-31

    The Intergovernmental Panel on Climate Change (IPCC) has identified forestry and other land-use based mitigation measures as possible sources and sinks of greenhouse gases. An overview of sequestration and biotic storage is presented, and the potential impacts of the use of carbon sequestration as a mitigation technology are briefly noted. Carbon sequestration is also compare to other mitigation technologies. Biotic mitigation technologies are concluded to be a legitimate and potentially important part of greenhouse gas mitigation due to their relatively low costs, ancillary benefits, and climate impact. However, not all biotic mitigation techniques perfectly match the idealized definition of a mitigation measure, and policies are becoming increasingly biased against biotic technologies.

    Energy technology innovation plays a crucial role in reducing carbon emissions. This paper investigates whether there is relationship between energy technology patents and CO 2 emissions of 30 provinces in mainland China during 1997–2008. Gross domestic product (GDP) is included in the study due to its impact on CO 2 emissions and energy technology innovation, thus avoiding the problem of omitted variable bias. Furthermore, we investigate three cross-regional groups, namely eastern, central and western China. The results show that domestic patents for fossil-fueled technologies have no significant effect on CO 2 emissions reduction; however, domestic patents for carbon-free energy technologies appear to play an important role in reducing CO 2 emissions, which is significant in eastern China, but is not significant in central, western and national level of China. The results of this study enrich energy technology innovation theories and provide some implications for energy technology policy making. - Highlights: ► We studied the causality between energy technology patents and CO 2 emissions using dynamic panel data approach. ► There is a long-run equilibrium relationship among energy technology patents, CO 2 emissions and GDP. ► Domestic patents for fossil-fueled technologies have no significant effect on CO 2 emissions reduction. ► Domestic patents for carbon-free energy technologies appear to play an important role in reducing CO 2 emissions. ► This study provides some references for the future energy technology policy making.

    Full Text Available This study aims at analyzing the variables of use and contact of users regarding to products and services of mobile phone technology. Technological innovation stands in the enterprise, enabling growth and creation of new products and services. In the theoretical framework, we used the technology readiness model, from users beliefs and feelings represented by four dimensions: optimism, innovativeness, discomfort and insecurity. It also highlights the technology acceptance model and presents two important constructs as perceived usefulness and ease of use. In short, the factors that support the technology readiness model could be preceding the technology acceptance model. To conduct this study, a field survey of students at the Federal University of Uberlândia / Campus FACIP was carried out. Results indicate optimism as the main factor to accept new mobile technology, due to the fact that the mobile devices provide benefits to people's lives and prompt them a positive attitude toward mobile technology. The perception of the user to purchase a mobile device is directly related to its usefulness and ease of handling of the technology.

    Bates, Matthew E; Grieger, Khara D; Trump, Benjamin D; Keisler, Jeffrey M; Plourde, Kenton J; Linkov, Igor

    2016-01-05

    Emerging technologies present significant challenges to researchers, decision-makers, industry professionals, and other stakeholder groups due to the lack of quantitative risk, benefit, and cost data associated with their use. Multi-criteria decision analysis (MCDA) can support early decisions for emerging technologies when data is too sparse or uncertain for traditional risk assessment. It does this by integrating expert judgment with available quantitative and qualitative inputs across multiple criteria to provide relative technology scores. Here, an MCDA framework provides preliminary insights on the suitability of emerging technologies for environmental remediation by comparing nanotechnology and synthetic biology to conventional remediation methods. Subject matter experts provided judgments regarding the importance of criteria used in the evaluations and scored the technologies with respect to those criteria. The results indicate that synthetic biology may be preferred over nanotechnology and conventional methods for high expected benefits and low deployment costs but that conventional technology may be preferred over emerging technologies for reduced risks and development costs. In the absence of field data regarding the risks, benefits, and costs of emerging technologies, structuring evidence-based expert judgment through a weighted hierarchy of topical questions may be helpful to inform preliminary risk governance and guide emerging technology development and policy.

    Potts, M; Atkinson, L

    1984-06-01

    A question of the 1980s is how will contraceptive technology contribute to improving family planning services to meet the goal of making available a simple, safe, effective, and widely acceptable contraceptive method. Significant changes in existing technology in the 1970s resulted in safer and more effective contraceptive methods. Voluntary sterilization emerged as the primary method in developed and developing countries, as important modifications simplified the procedure for women. The tolerance and effectiveness of the IUD were improved by reducing its size, adding copper to its surface, or encapsulating progesterone within it. The steroid content of the birth control pill was reduced 10-fold, leading to fewer side effects, and the pill was found to be an effective postcoital contraceptive when taken at specific intervals. Vacuum aspiration for the termination of 1st trimester pregnancy proved to be 1 of the safest surgical techniques practiced. Belated attention is now being focused on adapting existing contraceptive methods for use during the postpartum period and breast feeding. The insertion of an IUD immediately following childbirth is a particularly useful option in the developing world as an increasing number of women have their babies in urban hospitals. A method of enhancing the contraceptive effect of breast feeding should neither change milk production nor transfer the drug to the nursing infant. Fortunately, progestin-only pills have been found to have no effect on breast milk and an attempt is being made to expand the use of this approved method. More simplification of female sterilization is needed. Current techniques require back-up facilities in case of complications and are unlikely to meet the developing world's enormous demand. 2 methods not widely used -- spermicides and periodic abstinence -- are coming under new scrutiny. In mid-1983 the US Food and Drug Administration approved a spermicide-impregnanated disposable sponge for over

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    Ceramics are required for a number of applications in fusion reactors. In several of these applications, the thermal conductivity is an important design parameter as it affects the level of temperature and thermal stress in service. Ceramic insulators are known to suffer substantial reduction in thermal conductivity due to neutron irradiation damage. The present study estimates the reduction in thermal conductivity at high temperature due to radiation induced defects. Point, extended, and extended partly transparent defects are considered

    Full Text Available Biodiesel is a fuel with various benefits over the conventional diesel fuel. It is derived from renewable resources, it has less emission to environment, it is biodegradable so has very limited toxicity and above all its production can be decentralized so that it could have a potential in helping rural economies. However, there are also some worth mentioning challenges associated with production of biodiesel. Among them repeatedly mentioned are the cost of feedstock and the choice of convenient technology for efficient production of the fuel from diverse feedstock types. There are four main routes by which raw vegetable oil and/or animal fat can be made suitable for use as substituent fuel in diesel engines without modification. These are direct use or blending of oils, micro-emulsion, thermal cracking or pyrolysis and transesterification reaction. Due to the quality of the fuel produced, the transesterification method is the most preferred way to produce biodiesel from diverse feedstock types. Through this method, oils and fats (triglycerides are converted to their alkyl esters with reduced viscosity to near diesel fuel levels. There are different techniques to carry out transesterification reaction for biodiesel production. Each technique has its own advantages and disadvantages as well as its own specifically convenient feedstock character. There are also some very important reaction conditions to be given due attention in each of this techniques for efficient production of biodiesel, such as molar ratio of alcohol to oil, type and amount of catalyst, reaction temperature, reaction time, reaction medium, type and relative amount of solvents, among others. This review is meant to investigate the main transesterification techniques for biodiesel production in terms of their choice of feedstock character as well as their determinately required reaction conditions for efficient biodiesel production, so that to give an overview on their advantages

    2006-01-01

    The main goal of this article is to determine whether cost reductions in different bioenergy systems can be quantified using the experience curve approach, and how specific issues (arising from the complexity of biomass energy systems) can be addressed. This is pursued by case studies on biofuelled combined heat and power (CHP) plants in Sweden, global development of fluidized bed boilers and Danish biogas plants. As secondary goal, the aim is to identify learning mechanisms behind technology development and cost reduction for the biomass energy systems investigated. The case studies reveal large difficulties to devise empirical experience curves for investment costs of biomass-fuelled power plants. To some extent, this is due to lack of (detailed) data. The main reason, however, are varying plant costs due to differences in scale, fuel type, plant layout, region etc. For fluidized bed boiler plants built on a global level, progress ratios (PRs) for the price of entire plants lies approximately between 90-93% (which is typical for large plant-like technologies). The costs for the boiler section alone was found to decline much faster. The experience curve approach delivers better results, when the production costs of the final energy carrier are analyzed. Electricity from biofuelled CHP-plants yields PRs of 91-92%, i.e. an 8-9% reduction of electricity production costs with each cumulative doubling of electricity production. The experience curve for biogas production displays a PR of 85% from 1984 to the beginning of 1990, and then levels to approximately 100% until 2002. For technologies developed on a local level (e.g. biogas plants), learning-by-using and learning-by-interacting are important learning mechanism, while for CHP plants utilizing fluidized bed boilers, upscaling is probably one of the main mechanisms behind cost reductions

    Dengue infection is an important arboviral infection in southeast Asia, especially in India. Neurological manifestations of dengue are increasingly recognized. We report an ischemic stroke due to dengue vasculitis in an 8-year-old child. We present a girl with a short febrile illness followed by episodic severe headache, with gradually progressive hemiparesis and visual impairment. Her brain magnetic resonance imaging revealed multiple infarctions in the anterior and posterior circulation. The magnetic resonance angiogram revealed irregular narrowing of bilateral middle cerebral arteries, right anterior cerebral artery, left posterior cerebral, and bilateral vertebral arteries suggestive of vasculitis. Her dengue serology was strongly positive for immunoglobulin M with 68.9 panbio units. The rest of the evaluation for pediatric stroke was unremarkable. She was treated with intravenous followed by oral corticosteroids and recovered totally with resolution of vasculitis on magnetic resonance angiogram over the next 3 months. This child illustrates possible immune-mediated vasculitis caused by dengue infection which is rather a rare presentation in a child who subsequently recovered well. One should consider dengue in childhood strokes in endemic regions. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Background. Cavernous angiomas are angiographically occult vascular malformations that are present in 0.4−0.9 % of people, and represent around 5% of all cerebrovascular malformations. They can be single or multiple, and sporadic or familial. The presence of multiple lesions is more frequent in familial cavernomatosis. Ten to 30 % are associated with familial clustering. Case report. We presented the case of a 43-year-old man, admitted to the Emergency Department due to unprovoked seizure during the wide awake and everyday activities. Neurological examination was with no focal signs. A 32-channel standard digital EEG was without any significant changes of normal baseline activity. After sleep deprivation EEG showed multifocal, bilateral and asymmetric polyspikes and sharpwaves activity. Hyperventilation induced generalized epileptiform discharges. MRI scan demonstrated multiple small cavernous angiomas. Neuropsychological testing demonstrated a delayed memory impairment. Neurosurgery treatment was not recommended, and the therapy with valproate 1 250 mg/day had an excellent efficacy with no singnificant adverse effects. Conclusion. This patient considered as a rare case with multiple cavernomatosis highlights the importance of neuroradiological examination in adult patients with the first epileptic seizure but with no focal neurological signs. .

    2014-07-01

    Full Text Available Objectives Discuss neuropsychiatric aspects and differential diagnosis of catatonic syndrome secondary to systemic lupus erythematosus (SLE in a pediatric patient. Methods Single case report. Result A 13-year-old male, after two months diagnosed with SLE, started to present psychotic symptoms (behavioral changes, hallucinations and delusions that evolved into intense catatonia. During hospitalization, neuroimaging, biochemical and serological tests for differential diagnosis with metabolic encephalopathy, neurological tumors and neuroinfections, among other tests, were performed. The possibility of neuroleptic malignant syndrome, steroid-induced psychosis and catatonia was also evaluated. A complete reversal of catatonia was achieved after using benzodiazepines in high doses, associated with immunosuppressive therapy for lupus, which speaks in favor of catatonia secondary to autoimmune encephalitis due to lupus. Conclusion Although catatonia rarely is the initial clinical presentation of SLE, the delay in recognizing the syndrome can be risky, having a negative impact on prognosis. Benzodiazepines have an important role in the catatonia resolution, especially when associated with parallel specific organic base cause treatment. The use of neuroleptics should be avoided for the duration of the catatonic syndrome as it may cause clinical deterioration.

    This study shows that the theft of copper, mainly from electrical wires, is becoming a more frequent crime as the value of this metal rises. We have collected all the data from the Burn Centre of the Hospital of Palermo, Italy, from 1992 to 2007. Over the last two decades, we assisted to a dramatic increase of patients admitted to our hospital, reporting burn injuries while attempting to steal it in dangerous conditions. The circumstances of the injury, the clinical management of the case, and the long-term consequences are presented and discussed. We found that the electrical burn related to the theft of copper is often a life-threatening event because of the high-voltage electrical current passing through the patients. Patients, due to the type of activity, often requiring physical effort, were generally young and healthy. From a review of the literature on the subject, we have noticed that theft of copper is not reported as an important risk factor for electrical burns. Our report clearly shows that theft of copper-related electrical injury is becoming more frequent in the community and should be added as a "new" risk factor. The already high incidence reported here may actually be lower than the actual incidence because many patients tend not to come to the hospital because of the risk of being prosecuted by the police.

    Pulmonary hypertension due to left heart disease, also known as group 2 pulmonary hypertension according to the European Society of Cardiology/European Respiratory Society classification, is the most common cause of pulmonary hypertension. In patients with left heart disease, the development of pulmonary hypertension favours right heart dysfunction, which has a major impact on disease severity and outcome. Over the past few years, this condition has been considered more frequently. However, epidemiological studies of group 2 pulmonary hypertension are less exhaustive than studies of other causes of pulmonary hypertension. In group 2 patients, pulmonary hypertension may be caused by an isolated increase in left-sided filling pressures or by a combination of this condition with increased pulmonary vascular resistance, with an abnormally high pressure gradient between arteries and pulmonary veins. A better understanding of the conditions underlying pulmonary hypertension is of key importance to establish a comprehensive diagnosis, leading to an adapted treatment to reduce heart failure morbidity and mortality. In this review, epidemiology, mechanisms and diagnostic approaches are reviewed; then, treatment options and future approaches are considered. Copyright © 2017. Published by Elsevier Masson SAS.

    The education of medical professionals is divided into medical studies, postgraduate training leading to the qualification as a specialist, and continuing professional development. During education, all scientific knowledge and practical skills are to be acquired, which enable the physician to practice responsibly in a specialized medical area. In the present article, relevant curricula are analyzed regarding the consideration of medical device-related topics, as the clinical application of medical technology has reached a central position in modern patient care. Due to the enormous scientific and technical progress, this area has become as important as pharmacotherapy. Our evaluation shows that medical device-related topics are currently underrepresented in the course of medical education and training and should be given greater consideration in all areas of medical education. Possible solutions are presented.

    1994-01-01

    Amongst the important scientific and technological revolutions of history there is none in which women have played such a substantial and many-sided role as in the development of nuclear energy. The birth of nuclear energy is not only due to Marie Curie and Lise Meitner but also to a large number of courageous 'nuclear women' who decided against all sorts of prejudices and resistances in favour of a life in research. Therefore the revolution of the atom has also become the greatest breakthrough of women in natural sciences. This double revolution is the subject of this book. Here the history of nuclear energy itself is dealt with documented with the original work and personal memories of different persons - mainly women - who have been substantially involved in this development.

    A national survey on environmental nuisances due to all forms of transport was made in France during 1977. From among the data gathered, it is possible to extract results concerning the impact of nuisance due to railways, partly from results of questionnaires and partly from results of acoustical measurements. Interviews and measurements were made in several towns, at randomly selected dwellings. Rail and air transport noise nuisance impacts appeared to be of comparable importance, with that of road transport very much larger than either. (0 refs).

    Limited natural resources increase the demand on highly efficient machinery and transportation means. New energy-saving mobility concepts call for design optimisation through downsizing of components and choice of corrosion resistant materials possessing high strength to density ratios. Component downsizing can be performed either by constructive structural optimisation or by substituting heavy materials with lighter high-strength ones. In this context, forging plays an important role in manufacturing load-optimised structural components. At the Institute of Metal Forming and Metal-Forming Machines (IFUM) various innovative forging technologies have been developed. With regard to structural optimisation, different strategies for localised reinforcement of components were investigated. Locally induced strain hardening by means of cold forging under a superimposed hydrostatic pressure could be realised. In addition, controlled martensitic zones could be created through forming induced phase conversion in metastable austenitic steels. Other research focused on the replacement of heavy steel parts with high-strength nonferrous alloys or hybrid material compounds. Several forging processes of magnesium, aluminium and titanium alloys for different aeronautical and automotive applications were developed. The whole process chain from material characterisation via simulation-based process design to the production of the parts has been considered. The feasibility of forging complex shaped geometries using these alloys was confirmed. In spite of the difficulties encountered due to machine noise and high temperature, acoustic emission (AE) technique has been successfully applied for online monitoring of forging defects. New AE analysis algorithm has been developed, so that different signal patterns due to various events such as product/die cracking or die wear could be detected and classified. Further, the feasibility of the mentioned forging technologies was proven by means

    2010-09-01

    Fresh meat is a highly perishable product due to its biological composition. Many interrelated factors influence the shelf life and freshness of meat such as holding temperature, atmospheric oxygen (O(2)), endogenous enzymes, moisture, light and most importantly, micro-organisms. With the increased demand for high quality, convenience, safety, fresh appearance and an extended shelf life in fresh meat products, alternative non-thermal preservation technologies such as high hydrostatic pressure, superchilling, natural biopreservatives and active packaging have been proposed and investigated. Whilst some of these technologies are efficient at inactivating the micro-organisms most commonly related to food-borne diseases, they are not effective against spores. To increase their efficacy against vegetative cells, a combination of several preservation technologies under the so-called hurdle concept has also been investigated. The objective of this review is to describe current methods and developing technologies for preserving fresh meat. The benefits of some new technologies and their industrial limitations is presented and discussed.

    Micro/nano-fabrication techniques, such as soft lithography and electrospinning, have been well-developed and widely applied in many research fields in the past decade. Due to the low costs and simple procedures, these techniques have become important and popular for biological studies. In this review, we focus on the studies integrating micro/nano-fabrication work to elucidate the molecular mechanism of signaling transduction in cell biology. We first describe different micro/nano-fabrication technologies, including techniques generating three-dimensional scaffolds for tissue engineering. We then introduce the application of these technologies in manipulating the physical or chemical micro/nano-environment to regulate the cellular behavior and response, such as cell life and death, differentiation, proliferation, and cell migration. Recent advancement in integrating the micro/nano-technologies and live cell imaging are also discussed. Finally, potential schemes in cell biology involving micro/nano-fabrication technologies are proposed to provide perspectives on the future research activities.

    The Finnish Technology Development Centre (Tekes) is responsible for the financing of research and development in the field of energy production technology. A considerable part of the financing goes to technology programmes. Each technology programme involves major Finnish institutions - companies, research institutes, universities and other relevant interests. Many of the energy technology programmes running in 1998 were launched collectively in 1993 and will be completed at the end of 1998. They are complemented by a number of other energy-related technology programmes, each with a timetable of its own. Because energy production technology is horizontal by nature, it is closely connected with research and development in other fields, too, and is an important aspect in several other Tekes technology programmes. For this reason this brochure also presents technology programmes where energy is only one of the aspects considered but which nevertheless contribute considerably to research and development in the energy production sector

  3. Power and LPG production with LNG import

    International Nuclear Information System (INIS)

    Mak, J.Y.

    2004-01-01

    When used in power cogeneration, Liquefied Natural Gas (LNG) is both energy efficient and can eliminate seawater or fuel gas consumption as well as the associated environmental impacts of conventional regasification processes. However, some liquefied natural gas (LNG) sources have heating values higher than current North American natural gas pipelines can allow for. LNG from these cannot be injected into gas pipelines without several heating control processing steps. This paper outlines two new technologies developed to address this issue. The first is a power cogeneration process using LNG as a heat sink. The second technology involves a fractionation process removing Liquid Propane Gas (LPG) components from imported LNG, thereby controlling heat value. Both technologies are applicable in grassroots installations as well as being suitable for retrofitting to existing LNG regasification for power generation and LPG production. It was concluded that power cogeneration with a mixed fluid power cycle recovered a significant portion of energy in LNG liquefaction plants. Additionally, it was also possible to fractionate high quality LPG from LNG at a low cost, with the residue being further re-condensed and re-utilized for power generation. It was also concluded that the LNG fractionation process would add flexibility to the LNG receiving terminals, allowing the import of lower quality LNG to North America, while also generating additional revenues from LPG production. 3 refs., 5 tabs., 6 figs

  11. Climate impacts from import of waste fuels; Klimatpaaverkan fraan import av braennbart avfall

    Energy Technology Data Exchange (ETDEWEB)

    Haraldsson, Maarten; Sundberg, Johan (Profu, Moelndal (Sweden))

    2009-04-15

    Imports of combustible waste has increased in recent years and imported waste has become an increasingly important fuel in the Swedish district heating systems. The projections for the next few years show that the imports can be much higher, partly due to reduced amounts of waste in the wake of economic downturn the world economy, partly because several new incinerators will be put into operation. In a environmental perspective, imports are controversial and it has been proposed that imports should be restricted. This report provides an assessment of the climate impact of importing waste for combustion. The report shows that greenhouse gas emissions due to imports of waste to the Swedish district heating plants in 2007 was reduced by 500 000 tonnes of carbon dioxide. This is equivalent to the emissions from 300 000 Swedes car journeys a year, or 2.5% of the total emission reduction target set by the Government for the non-trading sector until 2020. Imports of wood waste-chips accounts for the largest reduction, but the study shows that imports of other types of waste contribute to a reduction in emissions of greenhouse gases. The reasons for the reduction is that the use of imported waste fuel substitute for other heating and electricity generation, which gives the consequence that emissions are avoided. The largest emission reductions are obtained, however, by the importation of household waste by replacing the alternative waste treatment of the corresponding waste in the country of origin. In the countries from which imports of waste currently takes place there is a lack of treatment capacity for organic waste. The alternative treatment available is primarily deposition. This treatment causes significant emissions of methane, which is a very strong greenhouse gas. The shipment of waste that occur as a result of imports gives a marginal contribution of greenhouse gases, compared against the emission reductions outlined above

    It is shown that a bunch of charged particles following a curved path in a magnetic field is subject to a force due to its own electro-magnetic field. One aspect of this is a ''centrifugal'' force acting on individual particles in the bunch. A resonance mechanism, capable of disrupting the beam at modest currents, is given as an example of the importance of this force. The theory is tested with observations from the Cornell Electron Storage Ring. This force will cause important modifications to existing theories of accelerator stability

    Internet usage and accessibility has grown at a staggering rate, influencing technology use for healthcare purposes. The amount of health information technology (Health IT) available through the Internet is immeasurable and growing daily. Health IT is now seen as a fundamental aspect of patient care as it stimulates patient engagement and encourages personal health management. It is increasingly important to understand consumer health IT patterns including who is using specific technologies, how technologies are accessed, factors associated with use, and perceived benefits. To fully uncover consumer patterns it is imperative to recognize common barriers and which groups they disproportionately affect. Finally, exploring future demand and predictions will expose significant opportunities for health IT. The most frequently used health information technologies by consumers are gathering information online, mobile health (mHealth) technologies, and personal health records (PHRs). Gathering health information online is the favored pathway for healthcare consumers as it is used by more consumers and more frequently than any other technology. In regard to mHealth technologies, minority Americans, compared with White Americans utilize social media, mobile Internet, and mobile applications more frequently. Consumers believe PHRs are the most beneficial health IT. PHR usage is increasing rapidly due to PHR integration with provider health systems and health insurance plans. Key issues that have to be explicitly addressed in health IT are privacy and security concerns, health literacy, unawareness, and usability. Privacy and security concerns are rated the number one reason for the slow rate of health IT adoption. PMID:24904713

  8. IMPORTANT PROTOZOAN PARASITES IN INDONESIA

    Directory of Open Access Journals (Sweden)

    Srisasi Gandahusada

    2012-09-01

    Full Text Available The most important protozoan parasites in Indonesia are the malaria parasites, Toxoplasma gondii and Entamoeba histolytica. After the second world war the residual insecticides and effective antimalarial drugs were used in the control of malaria. After development of resistance among mosquitoes to insecticides, the Malaria Control Programme was switched over to the Malaria Eradication Programme. Malaria incidence dropped heavily. However, due to the quick development of vector resistance and financial limitations, malaria came back and so did the Malaria Control Programme. P. falciparum and P.vivax are the most common species in Indonesia. Important vectors are An. sundaicus, An. aconitus, An. maculatus, An. hyrcanus group, An. balabacensis, An. farauti etc. An. sundaicus and An. aconitus have developed resistance to DDT and Dieldrin in Java. In 1959 the Malaria Eradication Programme was started in Java, Bali and Lampung. In 1965 the API dropped to 0,15 per thousand. From 1966 onwards malaria transmission was on the increase, because spraying activities were slowed down, but dropped again from 1974 onwards by occasional residual house spraying with DDT or Fenitrothion, malaria surveillance and treatment of malaria cases, resulting in an API of 0.18 per thousand in 1987. At present malaria is not transmitted in Jakarta and in capitals of the provinces and kabupatens, except in Irian Jaya, Nusa Tenggara Timur and one or two other provinces, but it still exists in rural areas. The distribution of chloroquine resistant P.falciparum is patchy. Resistance is at the RI, RII and RUT levels. The main problems of malaria control are : the increasing development of resistance of the vector to insecticides, the change of An.aconitus from zoophili to anthropophili and from indoor to outdoor biting, the increasing resistance of P.falciparum to chloroquine, the shortage of skilled manpower and limitation of budget. In Indonesia many newborns with congenital

    2011-01-01

    Gamma ray astronomy is currently in an exciting period of multiple missions and a wealth of data. Results from INTEGRAL, Fermi, AGILE, Suzaku and Swift are making large contributions to our knowledge of high energy processes in the universe. The advances are due to new detector and imaging technologies. The steps to date have been from scintillators to solid state detectors for sensors and from light buckets to coded aperture masks and pair telescopes for imagers. A key direction for the future is toward focusing telescopes pushing into the hard X-ray regime and Compton telescopes and pair telescopes with fine spatial resolution for medium and high energy gamma rays. These technologies will provide finer imaging of gamma-ray sources. Importantly, they will also enable large steps forward in sensitivity by reducing background.

    Bringing quantum science and technology to the space frontier offers exciting prospects for both fundamental physics and applications such as long-range secure communication and space-borne quantum probes for inertial sensing with enhanced accuracy and sensitivity. But despite important terrestrial pathfinding precursors on common microgravity platforms and promising proposals to exploit the significant advantages of space quantum missions, large-scale quantum test beds in space are yet to be realised due to the high costs and lead times of traditional 'Big Space' satellite development. But the 'small space' revolution, spearheaded by the rise of nanosatellites such as CubeSats, is an opportunity to greatly accelerate the progress of quantum space missions by providing easy and affordable access to space and encouraging agile development. We review space quantum science and technology, CubeSats and their rapidly developing capabilities and how they can be used to advance quantum satellite systems.

  13. Adaptive Importance Sampling with a Rapidly Varying Importance Function

    International Nuclear Information System (INIS)

    Booth, Thomas E.

    2000-01-01

    It is known well that zero-variance Monte Carlo solutions are possible if an exact importance function is available to bias the random walks. Monte Carlo can be used to estimate the importance function. This estimated importance function then can be used to bias a subsequent Monte Carlo calculation that estimates an even better importance function; this iterative process is called adaptive importance sampling.To obtain the importance function, one can expand the importance function in a basis such as the Legendre polynomials and make Monte Carlo estimates of the expansion coefficients. For simple problems, Legendre expansions of order 10 to 15 are able to represent the importance function well enough to reduce the error geometrically by ten orders of magnitude or more. The more complicated problems are addressed in which the importance function cannot be represented well by Legendre expansions of order 10 to 15. In particular, a problem with a cross-section notch and a problem with a discontinuous cross section are considered

  14. Economics of power generation from imported biomass

    International Nuclear Information System (INIS)

    Lako, P.; Van Rooijen, S.N.M.

    1998-02-01

    Attention is paid to the economics of import of biomass to the Netherlands, and subsequent utilisation for power generation, as a means to reduce dependence on (imported) fossil fuels and to reduce CO2 emission. Import of wood to the extent of 40 PJ or more from Baltic and South American states seems to be readily achievable. Import of biomass has various advantages, not only for the European Union (reduced CO2 emissions) but also for the countries of origin (employment creation). However, possible disadvantages or risks should be taken into account. With that in mind, import of biomass from Baltic states seems very interesting, although it should be noted that in some of those countries the alternative of fuel-switching to biomass seems to be more cost-effective than import of biomass from those countries. Given the expected increase in inland biomass consumption in the Baltic countries and the potential substantial future demand for biomass in other Western European countries it is expected that the biomass supply from Baltic countries will not be sufficient to fulfill the demand. An early focus on import from other countries seems advisable. Several power generation options are available with short to medium term potential and long term potential. The margin between costs of biomass-fuelled power and of coal fired power will be smaller, due to substantial improvements in power generating efficiency and reductions of investment costs of options for power generation from biomass, notably Biomass Gasification Combined Cycle. 18 refs

  15. Research and Development Strategy in Biological Technologies: A Patent Data Analysis of Japanese Manufacturing Firms

    Directory of Open Access Journals (Sweden)

    Hidemichi Fujii

    2016-04-01

    Full Text Available Biological technology allows us to invent new medical approaches, create effective food production methods and reserves and develop new materials for industrial production. There is a diversity of biological technology types, and different technologies have different priorities for invention. This study examines the factors that are important for the invention of biology-related technologies in Japan using patent application data and a decomposition analysis framework. As the results show, patent applications related to biochemistry and biotechnology increased until 1995 because of the expanded scale of R&D activities and the high priority assigned to biological technology. However, the number of patent applications stagnated after 1995, because the importance of biochemistry, especially waste-gas treatment technologies, decreased. Additionally, patent applications for medicines and disease-related technologies increased rapidly from 1971 to 1995. The primary determinant of rapid growth is an increase in research priority, especially among firms in the chemical industry whose technologies are related to supplemental foods and foods with health-promoting benefits. Finally, patent applications involving foodstuff- and agriculture-related technologies increased from 1971 to 1995 due to increased R&D and the increased priority of biological technology.

    1994-02-01

    The Department of Energy's Office of Environmental Restoration and Waste Management (EM) is responsible for remediating its contaminated sites and managing its waste inventory in a safe and efficient manner. EM's Office of Technology Development (OTD) supports applied research and demonstration efforts to develop and transfer innovative, cost-effective technologies to its site clean-up and waste management programs within EM's Office of Environmental Restoration and Office of Waste Management. The purpose of the Technology Catalogue is to provide performance data on OTD-developed technologies to scientists and engineers assessing and recommending technical solutions within the Department's clean-up and waste management programs, as well as to industry, other federal and state agencies, and the academic community. OTD's applied research and demonstration activities are conducted in programs referred to as Integrated Demonstrations (IDs) and Integrated Programs (IPs). The IDs test and evaluate.systems, consisting of coupled technologies, at specific sites to address generic problems, such as the sensing, treatment, and disposal of buried waste containers. The IPs support applied research activities in specific applications areas, such as in situ remediation, efficient separations processes, and site characterization.

    Zanker, Sebastian; Marthaler, Michael; Schoen, Gerd [Institut fuer Theoretische Festkoerperphysik, Karlsruhe Institute of Technology, D-76128 Karlsruhe (Germany)

    2015-07-01

    We study dephasing of a superconducting qubit due to quasiparticle tunneling through a Josephson junction. While qubit decay due to tunneling processes is well understood within a golden rule approximation, pure dephasing due to BCS quasiparticles gives rise to a divergent golden rule rate. We calculate qubit dephasing due to quasiparticle tunneling beyond lowest order approximation in coupling between qubit and quasiparticles. Summing up a certain class of diagrams we show that qubit dephasing due to purely longitudinal coupling to quasiparticles leads to dephasing ∝ exp(-x(t)) where x(t) ∝ t{sup 3/2} for short time scales and x(t) ∝ tlog(t) for long time scales.

    2013-01-01

    With the development of Very-Deep Sub-Micron technologies, process variability is becoming increasingly important and is a very important issue in the design of complex circuits. Process variability is the statistical variation of process parameters, meaning that these parameters do not have always the same value, but become a random variable, with a given mean value and standard deviation. This effect can lead to several issues in digital circuit design.The logical consequence of this parameter variation is that circuit characteristics, as delay and power, also become random variables.

  9. Particle resuspension due to human walking

    International Nuclear Information System (INIS)

    Mana, Zakaria

    2014-01-01

    In nuclear facilities, during normal operations in controlled areas, workers could be exposed to radioactive aerosols (1 μm ≤ dp ≤ 10 μm). One of the airborne contamination sources is particles that are initially seeded on the floor and could be removed by workers while they are walking. During the outage of EDF nuclear facilities, there is a resuspension of some radionuclides in aerosol form (1 μm ≤ dp ≤ 10 μm). Since the number of co-activity will increase in reactors buildings of EDF, it becomes important to understand particle resuspension due to the activity of the operators to reduce their radiation exposure. The purpose of this Ph.D thesis is to quantify the resuspension of particles due to the progress of operators on a contaminated soil. Thus, the approach is to combine an aerodynamic resuspension model with numerical calculations of flow under a shoe, and then to characterize experimentally some input parameters of the model (particle diameter, adhesion forces, shoes motion). The resuspension model Rock'n'Roll proposed by Reeks and Hall (2001) was chosen because it describes physically the resuspension mechanism and because it is based on the moment of forces applied to a particle. This model requires two input parameters such as friction velocity and adhesion forces distribution applied on each particle. Regarding the first argument, numerical simulations were carried on using the ANSYS CFX software applied to a safety shoe in motion (digitized by 3D CAO); the mapping of friction velocity shows values of about 1 m.s -1 for an angular average velocity of 200 degrees.s -1 . As regards the second parameter, AFM (Atomic Force Microscopy) measurements were carried out with alumina and cobalt oxide particles in contact with epoxy surfaces representative of those encountered in EDF power plants. AFM provides the distribution of adhesion forces and reveals a much lower value than what can be calculated theoretically using JKR model (Johnson

    2012-01-01

    Human space exploration has always been heavily influenced by goals to achieve a specific mission on a specific schedule. This approach drove rapid technology development, the rapidity of which adds risks as well as provides a major driver for costs. The National Aeronautics and Space Administration (NASA) is now approaching the extension of human presence throughout the solar system by balancing a proactive yet less schedule-driven development of technology with opportunistic scheduling of missions as the needed technologies are realized. This approach should provide cost effective, low risk technology development that will enable efficient and effective manned spaceflight missions. As a first step, the NASA Human Spaceflight Architecture Team (HAT) has identified a suite of critical technologies needed to support future manned missions across a range of destinations, including in cislunar space, near earth asteroid visits, lunar exploration, Mars space, and Mars exploration. The challenge now is to develop a strategy and plan for technology development that efficiently enables these missions over a reasonable time period, without increasing technology development costs unnecessarily due to schedule pressure, and subsequently mitigating development and mission risks. NASA fs Johnson Space Center (JSC), as the nation's primary center for human exploration, is addressing this challenge through an innovative approach allocating Internal Research and Development funding to projects that have been prioritized using four focus criteria, with appropriate importance weighting. These four focus criteria are the Human Space Flight Technology Needs, JSC Core Technology Competencies, Commercialization Potential, and Partnership Potential. The inherent coupling in these focus criteria have been captured in a database and have provided an initial prioritization for allocation of technology development research funding. This paper will describe this process and this database

  11. Importance analysis for reconfigurable systems

    Si, Shubin; Levitin, Gregory; Dui, Hongyan; Sun, Shudong

    2014-01-01

    Importance measures are used in reliability engineering to rank the system components according to their contributions to proper functioning of the entire system and to find the most effective ways of reliability enhancement. Traditionally, the importance measures do not consider the possible change of system structure with the improvement of specific component reliability. However, if a component's reliability changes, the optimal system structure/configuration may also change and the importance of the corresponding component will depend on the chosen structure. When the most promising component reliability improvement is determined, the component importance should be taken into account with respect to the possible structure changes. This paper studies the component reliability importance indices with respect to the changes of the optimal component sequencing. This importance measure indicates the critical components in providing the system reliability enhancement by both enhancing the component's reliability and reconfiguring the system. Examples of linear consecutive-k-out-of-n: F and G systems are considered to demonstrate the change of the component Birnbaum importance with the optimal system reconfiguration. The results show that the change of the importance index corresponds to the change of the system optimal configuration and the importance index can change not monotonically with the variation of the component reliability

  4. Modelling diffusion feedbacks between technology performance, cost and consumer behaviour for future energy-transport systems

    Tran, Martino; Brand, Christian; Banister, David

    2014-04-01

    Emerging technologies will have important impacts on sustainability objectives. Yet little is known about the explicit feedbacks between consumer behaviour and technological change, and the potential impact on mass market penetration. We use the UK as a case-study to explore the dynamic interactions between technology supply, performance, cost, and heterogeneous consumer behaviour and the resulting influence on long term market diffusion. Simulations of competing vehicle technologies indicate that petrol hybrids (HEVs) dominate the market over the long-term because they benefit from improved performance and are able to reach the steep part of the diffusion curve by 2025 while competing technologies remain in the early stages of growth and are easier to displace in the market. This is due to the cumulative build-up of stock and slow fleet turnover creating inertia in the technological system. Consequently, it will be difficult to displace incumbent technologies because of system inertia, cumulative growth in stock, long operational life, and consumer risk aversion to new unproven technologies. However, when accounting for both technological and behavioural change, simulations indicate that if investment can reach 30-40% per annum growth in supply, combined with steady technology improvements, and more sophisticated agent decision making such as accounting for full technology lifecycle cost and performance, full battery electric vehicles could displace the incumbent system by 2050.

  5. Beam heat load due to geometrical and resistive wall impedance in COLDDIAG

    2012-11-01

    One of the still open issues for the development of superconductive insertion devices is the understanding of the heat intake from the electron beam. With the aim of measuring the beam heat load to a cold bore and the hope to gain a deeper understanding in the underlying mechanisms, a cold vacuum chamber for diagnostics (COLDDIAG) was built. It is equipped with the following instrumentation: retarding field analyzers to measure the electron flux, temperature sensors to measure the beam heat load, pressure gauges, and mass spectrometers to measure the gas content. Possible beam heat load sources are: synchrotron radiation, wakefield effects due to geometrical and resistive wall impedance and electron/ion bombardment. The flexibility of the engineering design will allow the installation of the cryostat in different synchrotron light sources. COLDDIAG was first installed in the Diamond Light Source (DLS) in 2011. Due to a mechanical failure of the thermal transition of the cold liner, the cryostat had to be removed after one week of operation. After having implemented design changes in the thermal liner transition, COLDDIAG has been reinstalled in the DLS at the end of August 2012. In order to understand the beam heat load mechanism it is important to compare the measured COLDDIAG parameters with theoretical expectations. In this paper we report on the analytical and numerical computation of the COLDDIAG beam heat load due to coupling impedances deriving from unavoidable step transitions, ports used for pumping and diagnostics, surface roughness, and resistive wall. The results might have an important impact on future technological solutions to be applied to cold bore devices.

  7. Exploration Mission Benefits From Logistics Reduction Technologies

    Broyan, James Lee, Jr.; Schlesinger, Thilini; Ewert, Michael K.

    2016-01-01

    Technologies that reduce logistical mass, volume, and the crew time dedicated to logistics management become more important as exploration missions extend further from the Earth. Even modest reductions in logical mass can have a significant impact because it also reduces the packing burden. NASA's Advanced Exploration Systems' Logistics Reduction Project is developing technologies that can directly reduce the mass and volume of crew clothing and metabolic waste collection. Also, cargo bags have been developed that can be reconfigured for crew outfitting and trash processing technologies to increase habitable volume and improve protection against solar storm events are under development. Additionally, Mars class missions are sufficiently distant that even logistics management without resupply can be problematic due to the communication time delay with Earth. Although exploration vehicles are launched with all consumables and logistics in a defined configuration, the configuration continually changes as the mission progresses. Traditionally significant ground and crew time has been required to understand the evolving configuration and locate misplaced items. For key mission events and unplanned contingencies, the crew will not be able to rely on the ground for logistics localization assistance. NASA has been developing a radio frequency identification autonomous logistics management system to reduce crew time for general inventory and enable greater crew self-response to unplanned events when a wide range of items may need to be located in a very short time period. This paper provides a status of the technologies being developed and there mission benefits for exploration missions.

  8. EVALUATION OF TECHNOLOGICAL INTENSITY OF EXPORTS IN THE FORESTRY SECTOR

    Directory of Open Access Journals (Sweden)

    Orlando Monteiro da Silva

    2016-04-01

    Full Text Available ABSTRACT One of the fastest growing sectors in the domestic industry is the forestry, which has contributed significantly to economic development, job creation, income taxes, putting Brazil in a prominent position in the world market. This paper analyzes the evolution of the technological intensity of 12 main products exported by the sector, from 2000 to 2011. For that, utilizes an indicator called PRODY, which allows classifying different products according to their technological intensity or income content and considers the GDP per capita of exporting countries of each product, weighted by its revealed comparative advantage. It can be seen by the results, a continuous growth in all products' technology indicators and their decomposition into income effects, comparative advantage and joint effects, allowed to verify the main causes of this growth. Products with lower PRODY values are those that presented a higher evolution during the period studied. Products of higher processing, and those from pulp and paper industry, had greater technological advances, thanks to a joint effect, while the ones of lower processing, had a technological improvement due to the increase in GDP per capita in exporting countries. Sawn wood was the standout product, being the only one who proved to be dependent of comparative advantage effect, confirming that this industry has been reinventing itself and incorporating, in fact, more technology. This study revealed the importance of technological intensification to generate comparative advantage and be able to stand against international competition.

  9. Cost uncertainty for different levels of technology maturity

    International Nuclear Information System (INIS)

    DeMuth, S.F.; Franklin, A.L.

    1996-01-01

    It is difficult at best to apply a single methodology for estimating cost uncertainties related to technologies of differing maturity. While highly mature technologies may have significant performance and manufacturing cost data available, less well developed technologies may be defined in only conceptual terms. Regardless of the degree of technical maturity, often a cost estimate relating to application of the technology may be required to justify continued funding for development. Yet, a cost estimate without its associated uncertainty lacks the information required to assess the economic risk. For this reason, it is important for the developer to provide some type of uncertainty along with a cost estimate. This study demonstrates how different methodologies for estimating uncertainties can be applied to cost estimates for technologies of different maturities. For a less well developed technology an uncertainty analysis of the cost estimate can be based on a sensitivity analysis; whereas, an uncertainty analysis of the cost estimate for a well developed technology can be based on an error propagation technique from classical statistics. It was decided to demonstrate these uncertainty estimation techniques with (1) an investigation of the additional cost of remediation due to beyond baseline, nearly complete, waste heel retrieval from underground storage tanks (USTs) at Hanford; and (2) the cost related to the use of crystalline silico-titanate (CST) rather than the baseline CS100 ion exchange resin for cesium separation from UST waste at Hanford

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

However, for Ukraine, in the burial sites of radiation and other wastes is urgent issue of protection of underground space in places with deep impermeable layer. Classical methods can not fully solve such problems. To solve them, you need to develop innovative technology to create such a screen, which will lie authentic sole object to be protected, at the project depth. For the experiments, it is necessary to choose the most important indicator, and technological factors affecting it. This is due to the fact that the proposed technology provides for lesser known technical solutions, the use of which should ultimately result in impervious screens with desired properties. Goal. The aim of this study is the selection of technological parameters of injection, design of experiments and the selection of indicators characterizing the efficient operation of the screen. Such constructs must first have almost zero permeability. In this paper, it was of interest to study the influence of process parameters on the filtration rate of the protective screen. Conclusion. As a result of the design of experiments, the basic technological factors that have a significant effect on the studied parameters. varying levels of these factors are also identified, which in turn makes it possible to determine the optimum process parameters creating a screen that meets all the desired properties and characteristics. Based on a series of experiments it is possible to obtain optimal formulations for different types of soils.

    Full Text Available In a new approach, the technology is taken into consideration as a resource of the business, in addition to the four traditional resources: material resources, financial resources, human resources and informational resources. This makes important for the managers to have solid technological knowledge, in addition to the economics. The research regarding the technological management (or the management of technology - MOT is lead by IAMOT (International Association in Management of Technology. There are a lot of connections between the technology on one side and the finances, the human resources, the marketing, the operational management on the other side. In our era the technology is more and more advanced and all the activities are strongly connected to it.

  20. Due diligence duties for an environmental liability

    Jurisdiction turned out well to create a basic ruling for due diligence duties. These due diligence duties are high standards for the law of torts (outside of contracts) within the Austrian civil law and represent a liability-extension for the holder of the source of danger. They establish an action for injunction in particular for preventing (further) damages. Therewith due diligence duties get a general sense in the range of a civil law for environmental liability. The responsible holder of a danger zone will therefore influence his way of acting to protect potential victims and the environment. The burden of proof is on the plaintiff (victims) under the Civil Code. Victims have specific sources of danger including high endangering special facilities in their argumentation with the so-called prima-facie-proof or first-appearance-proof. A turning back of the presentation of evidence to the polluter is wrong. The polluter himself has a continuing liability for dangerous activities and his clerks in the case of an extremely high danger of damage. All due diligence duties can be arranged in three areas: in information-, danger-avoidance- and danger-prevention-duties. The determination of range and essence of the duties has to be adjusted to each individual case. The range of the specific danger area is the essential link. The intensity of due diligence duties is increasing with the size of danger in the way of a movable system depending on the protected interest. Due diligence duties have to be kept within reasonable limits with two criterions: necessarity and demand. Proportionality of actions is a third criterion to avoid exaggeration of due diligence duties to obtain an effective protection for victims including the environment. (author)

    The United States Department of Energy (DOE) continually seeks safer and more cost-effective technologies for use in deactivation and decommissioning (D and D) of nuclear facilities. The Deactivation and Decommissioning Focus Area (DDFA) of the DOE's Office of Science and Technology (OST) sponsors large-scale demonstration and deployment projects (LSDDPs). At these LSDDPs, developers and vendors of improved or innovative technologies showcase products that are potentially beneficial to the DOE's projects and to others in the D and D community. Benefits sought include decreased health and safety risks to personnel and the environment, increased productivity, and decreased costs of operation. The Idaho National Engineering and Environmental Laboratory (INEEL) generated a list of statements defining specific needs and problems where improved technology could be incorporated into ongoing D and D tasks. One such need is to reduce the volume of waste copper wire and cable generated by D and D. Deactivation and decommissioning activities of nuclear facilities generates hundreds of tons of contaminated copper cable, which are sent to radioactive waste disposal sites. The Copper Cable Recycling Technology separates the clean copper from contaminated insulation and dust materials in these cables. The recovered copper can then be reclaimed and, more importantly, landfill disposal volumes can be reduced. The existing baseline technology for disposing radioactively contaminated cables is to package the cables in wooden storage boxes and dispose of the cables in radioactive waste disposal sites. The Copper Cable Recycling Technology is applicable to facility decommissioning projects at many Department of Energy (DOE) nuclear facilities and commercial nuclear power plants undergoing decommissioning activities. The INEEL Copper Cable Recycling Technology Demonstration investigated the effectiveness and efficiency to recycle 13.5 tons of copper cable. To determine the effectiveness

    The import of electric power increased by 19% in 1999. Due to the decrease in the electric power export the net import of electric power increased even more. Electric power import from Sweden was 6000 GWh, import from Russia 5200 GWh and import from Norway 100 GWh. The electric power export in 1999 was only 200 GWh. The generation of nuclear power increased 5% and the consumption of wood-based fuels by 3%. The increase in nuclear power generation is based on increment of the power output capacities of the power plants. The consumption of peat decreased by 12% and the production of hydroelectric power by 15%. The decrement of the peat consumption is based on the changes in energy taxation. The production of hydroelectric power decreased to the normal level after the rainy year 1998. Oil consumption remained nearly the same as in 1998 even though the national product increased in 1999 by 3.5%. The wind power generation was doubled in 1999. The share of it is still only about 0.01% of the total energy consumption. Carbon dioxide emissions from coal and peat, decreased by 1.0 million tons, down to 56 million tons. The present emissions are now only about 2 million tons higher than during the reference year 1990. The emissions have decreased by 5 million tons since 1996 when they were at their highest

    Despite the development of new microbiologic technologies, blood cultures (BCs) remain the first-line tool for the diagnosis of bloodstream infections. Their diagnostic value may be affected when a microorganism of questionable evidence is isolated-for example, coagulase-negative staphylococci, Bacillus spp., viridans group streptococci, Corynebacterium spp., Propionibacterium spp. and Micrococcus spp. Finally, making a correct diagnosis of pathogenicity (vs. contamination) is challenging. To review the current ways of dealing with the problem of BC contaminants (BCCs) and to provide practical suggestions to decrease BCC rates. PubMed electronic databases and existing reviews were searched up to December 2017 to retrieve relevant publications related to the topic. This review describes the burden of BCC and analyses the main current issues and controversies in interpreting the occurrence of potential BC contaminants. It focuses on the best-described approaches to decide whether BCC is present and discusses the different strategies of prevention in adults. Each institution should have an efficient policy to prevent BCC, emphasizing the importance of following guidelines for prescribing and collecting BCs. Training healthcare workers should focus on detrimental influence on patient care and highlight the work and costs due to contaminants. The accurate differentiation of a contaminant from a true pathogen relies on a multidisciplinary approach and the clinical judgement of experienced practitioners.

    Y2K raises challenges for healthcare risk managers that go beyond information technology issues. This article explains that (1) too little public attention is being paid to equipment which may well have Y2K faults and (2) few standards have been articulated for dealing with problems. Healthcare risk managers therefore must return to basic due diligence principles and develop their own standards and protocols. The article explains how to do due diligence and outlines suggested steps for dealing with the non-information technology side of compliance due diligence.

    People with intellectual disabilities continue to underutilize technology, in part due to insufficient training. Because support staff professionals provide instructional support, how they perceive integrating new technologies is important for people with intellectual disabilities. The authors conducted a sequential mixed-methods exploratory study (quan→QUAL) including quantitative data from online surveys completed by 46 staff members and qualitative data from five focus groups attended by 39 staff members. Quantitative results show strong support for diverse technologies. In contrast, qualitative results suggest that staff members' support of technology decreases when they perceive that technology may jeopardize service users' safety or independence. Although staff members identified increasing independence as the main reason to use new technologies with service users, they also worried that technologies used to increase the social inclusion of service users may pose undue risk and thus may limit their embrace of technology. © 2017 John Wiley & Sons Ltd.

    A male in his early seventies complained of abdominal pain and diarrhea at 7h after ingesting a small piece of gratin from a box lunch prepared by a caterer. He was admitted to a hospital, but died 37 h later. Dozens of people who had eaten the same box lunch also complained of diarrhea. All of them recovered after medical treatment. A later investigation demonstrated Salmonella Enteritidis (SE) in the gratin from the box lunch. An autopsy revealed very severe typhloenteritis with edema and submucosal hemorrhage. The digestive tract contained fluid contents without foodstuffs. Bacteriological examination revealed SE in the contents of the lower ileum and large intestine. Based on these findings, we concluded that the cause of death was food poisoning due to SE. In this case, ingesting only a small piece of contaminated food caused fatal food poisoning due to SE. These results emphasize the importance of prevention against food poisoning due to Salmonella, particularly SE.

    Full Text Available Iron may accumulate in excess due to a mutation in the HFE gene that upregulates absorption or when it is ingested or infused at levels that exceed the body’s ability to clear it. Excess iron deposition in parenchymal tissue causes injury and ultimately organ dysfunction. Diabetes mellitus and hepatic cirrhosis due to pancreas and liver damage are just two examples of diseases that result from iron overload. Despite the rapid growth of information regarding iron metabolism and iron overload states, the most effective treatment is still serial phlebotomies. We present a patient who developed iron overload due to chronic ingestion of oral ferrous sulfate. This case illustrates the importance of querying geriatric patients regarding their use of nonprescription iron products without a medical indication.

    Over the course of the year 2000, five one-day workshops were conducted by the Center for Global Security Research at the Lawrence Livermore National Laboratory on threats that might come against the US and its allies in the 2015 to 2020 timeframe due to the global availability of advanced technology. These workshops focused on threats that are enabled by nuclear, missile, and space technology; military technology; information technology; bio technology; and geo systems technology. In December, an Integration Workshop and Senior Review before national leaders and experts were held. The participants and reviewers were invited from the DOE National Laboratories, the DOD Services, OSD, DTRA, and DARPA, the DOS, NASA, Congressional technical staff, the intelligence community, universities and university study centers, think tanks, consultants on national security issues, and private industry. For each workshop the process of analysis involved identification and prioritization of the participants' perceived most severe threat scenarios (worst nightmares), discussion of the technologies which enabled those threats, and ranking of the technologies' threat potentials. We were not concerned in this exercise with defining responses, although our assessment of each threat's severity included consideration of the ease or difficulty with which it might be countered. At the concluding Integration Workshop and Senior Panel Review, we brought the various workshops' participants together, added senior participant/reviewers with broad experience and responsibility, and discussed the workshop findings to determine what is most certain, and uncertain, and what might be needed to resolve our uncertainties. This document reports the consensus and important variations of both the reviewers and the participants. In all, 45 threats over a wide range of lethality and probability of occurrence were identified. Over 60 enabling technologies were also discussed. These are

  13. Technology in Muslim Moral Philosophy.

    2016-04-01

    The article explores the place, role and status of technology in Muslim moral philosophy. Invoking early Muslim encounters with technology the author makes the case why technology is already deeply embedded in contemporary Muslim bioethical thinking. Due to an absence of the philosophical grounding there remains some ambivalence as to why technology is essential to Muslim ethical thinking. Countering the techno-pessimists, the author makes a case in favor of compositional thinking, namely that our thinking itself is altered by our tools and our environment. Compositional thinking opposes the representational mode of thinking that creates a dichotomy between nature versus culture, and technology versus nature. One should, however, anticipate an environment in which technology would be beneficial and not be viewed as potentially harmful.

But, in addition to these innovations, a firm that intends to participate in the process of internationalization of its business activity can achieve it by developing a network of associations. This article points shortly to the creation of a network of strategic alliances (associations whose essential elements can be reduced to the following forms: Agreements of a global character, acquisition of a right, capital investing transactions, joint ventures and commercial agreements.

  16. Structural changes in a copper alloy due to helium implantation

    The most suitable nuclear fusion reaction for energy production occurs between the two heavy hydrogen isotopes, deuterium and tritium. Structural materials in fusion reactors will be exposed to helium implantation over a broad range of energies. The deformation and partial exfoliation of surface layers due to hydrogen isotopes and helium contribute to the total erosion of the first wall. For this reason, one of the most important criteria in the choice of materials for the first wall of fusion reactors is the material's damage resistance. Recent advances in developing nuclear fusion reactors reveal that efficient heat removal from plasma-facing components is very important. Copper and copper alloys are considered an attractive choice for transporting such a high heat flux without thermal damage as they have high thermal conductivity. In the present study the authors report on the structural changes in a copper alloy, due to the helium implantation on the very near surface area, observed by transmission electron microscopy
