    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.

  3. 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.

    2017-01-01

    Can imported technologies be socially constructed? Starting from this puzzling question, this essay reflects on the various methodologies with which one can narrate the stories of technology in modern Korea. A focus on technological innovations and how they have been shaped by their societal milieu forces one to leave out a large part of the technological experience, especially when the bulk of the technologies-in-use have been imported from abroad. This poses a serious problem for the history of technology in Korea, a nation that relied heavily on foreign technologies as it went through rapid economic growth in the latter twentieth century.

  13. Potential displacement of petroleum imports by solar energy technologies

    Energy Technology Data Exchange (ETDEWEB)

    DeLeon, P.; Jackson, B.L.; McNown, R.F.; Mahrenholz, G.J.

    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.

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

    International Nuclear Information System (INIS)

    Williams, Eric; Hittinger, Eric; Carvalho, Rexon; Williams, Ryan

    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%.

  18. Importance of RWT Drain Down Scenario due to MSO during a Fire

    International Nuclear Information System (INIS)

    Yim, Hyuntae; Bae, Yongbum

    2013-01-01

    In this paper, importance of RWT depletion scenario resulting from MSO is discussed. If a fire within the plant area results in spurious containment spray signal due to control circuit damage or concurrent spurious actuation of the containment spray pump and discharge valve, boric acid in the refueling water tank (RWT) would be discharged into the containment and the depletion of the boric acid used for reactivity control and primary inventory control during safe shutdown operation could occur for that reason. In this scenario, safe shutdown operation will be threatened by the loss of reactivity control and inventory control functions. This scenario is very likely because MSO occurred in only one train out of two trains of the system and be able to sufficiently lead to adverse impact to the safe shutdown function. However, because RWT is classified to equipment important to safety, the performance based methods such as operator manual action (OMA), fire modeling, or fire PSA can be applied to the resolution of this MSO noncompliance instead of deterministic compliance methods. When the operator manual action is applied to the resolution of this MSO scenario, then the feasibility and reliability of this operator manual action should be demonstrated by showing that the action is sufficiently accomplished within available time window. In addition to the time margin for this action, tools needed to this manual action, qualified personnel, local accessibility, relevant procedures, and sufficient indications should be also demonstrated

  1. The Importance of Technology Readiness in NASA Earth Venture Missions

    Wells, James E.; Komar, George J.

    2009-01-01

    The first set of Venture-class investigations share the characteristic that the technology should be mature and all investigations must use mature technology that has been modeled or demonstrated in a relevant environment (Technology Readiness Level (TRL) >5). Technology Readiness Levels are a systematic metric/measurement system that supports assessments of the maturity of a particular technology and the consistent comparison of maturity between different types of technology. The TRL is used in NASA technology planning. A major step in the level of fidelity of the technology demonstration follows the completion of TRL 5. At TRL 6, a system or subsystem model or prototype must be demonstrated in a relevant environment (ground or space) representative model or prototype system or system, which would go well beyond ad hoc, "patch-cord," or discrete component level breadboarding. These TRL levels are chosen as target objectives for the Program. The challenge for offerors is that they must identify key aspects (uncertainty, multi subsystem complexity, etc) of the TRL estimate that should be properly explained in a submitted proposal. Risk minimization is a key component of the Earth Venture missions. Experiences of prior airborne missions will be shared. The discussion will address aspects of uncertainty and issues surrounding three areas of airborne earth science missions: (1) Aircraft or proposed flight platform -- Expressing the capability of the aircraft in terms of the supporting mission requirements. These issues include airplane performance characteristics (duration, range, altitude, among others) and multiship complexities. (2) Instruments -- Establishing that the instruments have been demonstrated in a relevant environment. Instruments with heritage in prior space missions meet this requirement, as do instruments tested on the ground. Evidence that the instruments have demonstrated the ability to collect data as advertised will be described. The complexity of

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

    International Nuclear Information System (INIS)

    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

  4. Importance of nuclear technology in the conservation and production of nutritional fungi

    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.

    This study investigates recent changes related to the import and export of medical technology and their results in Turkey. Between 1980 and 1993 the number of medical technology imports in Turkey rose, and there was a parallel rise in its ratio to total imports and health expenditures. In contrast the ratio of medical technology exports to total exports decreased significantly in the same period. The liberalization of foreign trade and the changes of health services toward free market policy has caused growing import of medical technology in Turkey.

  6. Technical Solutions to Mitigate Reliability Challenges due to Technology Scaling of Charge Storage NVM

    2013-01-01

    Full Text Available Charge storage nonvolatile memory (NVM is one of the main driving forces in the evolution of IT handheld devices. Technology scaling of charge storage NVM has always been the strategy to achieve higher density NVM with lower cost per bit in order to meet the persistent consumer demand for larger storage space. However, conventional technology scaling of charge storage NVM has run into many critical reliability challenges related to fundamental device characteristics. Therefore, further technology scaling has to be supplemented with novel approaches in order to surmount these reliability issues to achieve desired reliability performance. This paper is focused on reviewing critical research findings on major reliability challenges and technical solutions to mitigate technology scaling challenges of charge storage NVM. Most of these technical solutions are still in research phase while a few of them are more mature and ready for production phase. Three of the mature technical solutions will be reviewed in detail, that is, tunnel oxide top/bottom nitridation, nanocrystal, and phase change memory (PCM. Key advantages and reported reliability challenges of these approaches are thoroughly reviewed in this paper. This paper will serve as a good reference to understand the future trend of innovative technical solutions to overcome the reliability challenges of charge storage NVM due to technology scaling.

    Antonio Eduardo Ramires Santoro

    2017-06-01

    Full Text Available Due to technological advances, new means of obtaining information have been brought up to the field of criminal procedure, among them, the interception of telephone communication. Law 9.296/96 has introduced new actors on to the probative subsystem that play a direct part on the production/gathering of information that may be taken in consideration by the judge. The inexistence of proper procedural regulation that delimitates the manner in which such investigation must be carried out, the defense finds grave difficulty to try and trace the source of the proof. Fearing the risks associated with the production of defective evidence, the present study focuses on the importance of the chain of custody as a mean to track and assure the reliability of set information. With the purpose of knowing the rite to obtain the data through telephone interception and the verifying its credibility, a theoretical-bibliographic study was carried out and combined with an analysis of the statistics on means of investigation of proof provided by the CNJ and, finally, followed by an analysis of the technology systems developed to carry out the interception of communications measure.

    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.

    2015-01-01

    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.

    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.

    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)

    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.

  19. Technology Transfer in the EU: Exporting Strategically Important ICT Solutions to Other EU Member States

    Full Text Available The fast development of ICTs pose new challenges to the European Union and its Member States. Every EU country has its own policies regarding technology transfer, ownership of state e-services, and the possibilities how the state-owned or licensed e-service could be exported. Taking into account the free movement of goods, the EU has created a platform to cooperate and export IT solutions. However, the lack of preparedness of infrastructures, legislation and stakeholders for cross-border exchanges poses a threat to IT transfer and should be taken into consideration in the EU as well. In the coming decades the number of outsourced ICT solutions, strategically important ICT solutions, public services and critically important information exchange platforms developed on behalf of the states, will grow exponentially. Still, digital development is uneven across the EU, they grow at different speeds and the performance is quite splintered. There are legal provisions which are outdated and therefore impede technological cooperation and export of IT solutions. A Member State may restrict the ICT licensing based on national security and policy reasons and the ownership of intellectual property might pose a threat to technology transfer or further development of the IT solution. There are examples of strategically important export of ICT solutions, the experience at which can be expanded to cover other EU Member States. Strong collaboration would enable mutual learning from past experiences along with the opportunities for better use of technology. Parallels can be drawn with military technology transfers, as the policies and legal framework was first developed and mostly used with them.

    , 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......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...... 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...

    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.

    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.

    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.

  8. 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

    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.

  10. Sporadic error probability due to alpha particles in dynamic memories of various technologies

    1980-01-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Dominik Marchowski

    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.

    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 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.

    To report a case of antenatally diagnosed congenital mesoblastic nephroma in an assisted reproductive technology (ART) conception. Case report. Tertiary care university-affiliated hospital. 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.

    Wilkes, W.R.

    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

    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 This study investigates the level of technological enhancement of normally occurring radioactive materials (TENORM in the red mud waste due to the production of alumina in Jamaica. Technological enhancements factors (TEF were determined for the uranium, thorium, actinium series, their progenies, and the nonseries potassium-40 using gamma spectrometry. The study concluded that bauxite production technologically enhances the uranium progenies Th-234, Pb-214, Bi-214, and Pa-234 and the thorium-232 progenies Ac-228, Pb-212, and Bi-212 in red mud. The actinium series was technologically enhanced, but K-40 and the thorium daughter, Tl-208, were reduced. The spectrometric comparison of Tl-208 (at 510 keV was unexpected since its other photopeaks at 583 keV, 934 keV, and 968 keV were markedly different. An explanation for this anomaly is discussed. An explanation regarding the process of accumulation and fractionation of organically derived phosphate deposits and potassium-feldspar is offered to explain the spectrometric differences between the alumina product and its waste material, red mud.

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.

  3. Drainage Adits in Upper Silesia - Industrial Technology Heritage and Important Elements of the Hydrotechnical Infrastructure

    Duży, Stanisław; Dyduch, Grzegorz; Preidl, Wojciech; Stacha, Grzegorz

    2017-12-01

    Adits played an important role in the hydrotechnical infrastructure for centuries. Initially, they were used mainly to drain wetland and supply water to the population. There were also inherent in the conduct of mining activities. They were used as exploratory, development and supply headings. Their usual function was to drain, ventilate and transport, and after the cessation of mining they became important elements of the hydrotechnical infrastructure in the transformed mining areas. The article presents issues related to the revitalization of the Main Key Hereditary Adit and Friedrich Adit as essential for the areas in which they are located. Both are hydraulic structures with the possibility of adaptation for tourism purposes. The need to consider some technical activities to be undertaken in this type of objects was pointed out, not only including aspects related to their proper protection so that they can continue to safely perform their function, but also to the preservation of their historical values. Due to their age and the method of drilling used in them, those headings are often included in the list of monuments and protected by law.

  4. Development of import subtituting technologies for increasing productivity of sintering machines and strength of agglomerates

    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.

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    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

  15. 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.

    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.

  4. 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.

    2016-01-01

    In the first theoretical paper on joint audits, Deng et al. predict that the audit fees for joint audits will be lower than those from single audits. However, the prediction depends on the combination of audit firms involved in the joint audit and on their technology efficiency as well...... as on the liability involved. This paper is the first to empirically test the predictions. Our findings from Denmark do not indicate any general difference in audit fees when two audit firms – regardless of combination and technology efficiency – conduct the statutory audit compared to a single Big audit firm....... The results indicate the existence of fixed coordination costs in joint audits. We do, however, find higher audit fees in Big-Small joint audits when the Small audit firm has a share of less than 25 per cent. This may reflect free-riding concerns....

    Ghosn, Mohamad G; Shah, Dipan J

    2014-01-01

    Cardiac magnetic resonance has become a well-established imaging modality and is considered the gold standard for myocardial tissue viability assessment and ventricular volumes quantification. Recent technological hardware and software advancements in magnetic resonance imaging technology have allowed the development of new methods that can improve clinical cardiovascular diagnosis and prognosis. The advent of a new generation of higher magnetic field scanners can be beneficial to various clinical applications. Also, the development of faster acquisition techniques have allowed mapping of the magnetic relaxation properties T1, T2, and T2* in the myocardium that can be used to quantify myocardial diffuse fibrosis, determine the presence of edema or inflammation, and measure iron within the myocardium, respectively. Another recent major advancement in CMR has been the introduction of three-dimension (3D) phase contrast imaging, also known as 4D flow. The following review discusses key advances in cardiac magnetic resonance technology and their potential to improve clinical cardiovascular diagnosis and outcomes.

    Paediatric tonsillectomy is a common procedure and one of the first skills acquired by surgical trainees. Post-tonsillectomy bleeding is one of the most significant complications. This study examined post-tonsillectomy bleed rates associated with technology and level of surgical experience. Data were collected on all tonsillectomies performed by surgical consultants (n = 6) and trainees (n = 10) at affiliated hospitals over a nine-month period. Hospital records were audited for post-tonsillectomy bleeding re-admissions and returns to the operating theatre. A total of 1396 tonsillectomies were performed (279 by trainees, 1117 by consultant surgeons). Primary post-tonsillectomy bleed rates were equivalent between trainees and consultants. Secondary bleed rates were significantly greater for trainees (10.0 per cent) compared to consultants (3.3 per cent), as were return to operating theatre rates (2.5 per cent vs 0.7 per cent). Amongst consultants, technology used was not associated with differences in secondary post-tonsillectomy bleeding and returns to the operating theatre. Our data suggest that experience of the surgeon may have greater bearing on post-tonsillectomy bleed rates than the technology used.

    2012-06-01

    The upper-extremity portion of the Fugl-Meyer Scale (UE-FM) is one of the most established and commonly used outcome measures in stroke rehabilitative trials. Empirical work is needed to determine the amount of change in UE-FM scores that can be regarded as important and clinically meaningful for health professionals, patients, and other stakeholders. This study used anchor-based methods to estimate the clinically important difference (CID) for the UE-FM in people with minimal to moderate impairment due to chronic stroke. One hundred forty-six individuals with stable, mild to moderate upper-extremity (UE) hemiparesis were administered the UE-FM before and after an intervention targeting their affected UEs. The treating therapists rated each participant's perceived amount of UE motor recovery on a global rating of change (GROC) scale evaluating several facets of UE movement (grasp, release, move the affected UE, perform 5 important functional tasks with the affected UE, overall UE function). Estimated CID of the UE-FM scores was calculated using receiver operating characteristic (ROC) curve with the GROC scores as the anchor. The ROC curve analysis revealed that change in UE-FM scores during the intervention period distinguished participants who experienced clinically important improvement from those that did not based on the therapists' GROC scores. The area under the curve ranged from 0.61 to 0.70 for the different facets of UE movement. The estimated CID of the UE-FM scores ranged from 4.25 to 7.25 points, depending on the different facets of UE movement.

    2017-02-01

    Over the last few decades, there has been a significant increase in epidemiological studies suggesting that type 2 diabetes (T2DM) is linked to a higher risk of Alzheimer's disease (AD). However, how T2DM affects AD pathology, such as tau hyperphosphorylation, is not well understood. In this study, we investigated the impact of T2DM on tau phosphorylation in ob/ob mice, a spontaneous genetic model of T2DM. Tau phosphorylation at the AT8 epitope was slightly elevated in 4-week-old ob/ob mice while 26-week-old ob/ob mice exhibited tau hyperphosphorylation at multiple tau phospho-epitopes (Tau1, CP13, AT8, AT180, PHF1). We then examined the mechanism of tau hyperphosphorylation and demonstrated that it is mostly due to hypothermia, as ob/ob mice were hypothermic and normothermia restored tau phosphorylation to control levels. As caffeine has been shown to be beneficial for diabetes, obesity and tau phosphorylation, we, therefore, used it as therapeutic treatment. Unexpectedly, chronic caffeine intake exacerbated tau hyperphosphorylation by promoting deeper hypothermia. Our data indicate that tau hyperphosphorylation is predominately due to hypothermia consequent to impaired thermoregulation in ob/ob mice. This study establishes a novel link between diabetes and AD, and reinforces the importance of recording body temperature to better assess the relationship between diabetes and AD.

    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.

  18. Life cycle assessment of waste paper management: The importance of technology data and system boundaries in assessing recycling and incineration

    The significance of technical data, as well as the significance of system boundary choices, when modelling the environmental impact from recycling and incineration of waste paper has been studied by a life cycle assessment focusing on global warming potentials. The consequence of choosing a specific set of data for the reprocessing technology, the virgin paper manufacturing technology and the incineration technology, as well as the importance of the recycling rate was studied. Furthermore, the system was expanded to include forestry and to include fossil fuel energy substitution from saved biomass, in order to study the importance of the system boundary choices. For recycling, the choice of virgin paper manufacturing data is most important, but the results show that also the impacts from the reprocessing technologies fluctuate greatly. For the overall results the choice of the technology data is of importance when comparing recycling including virgin paper substitution with incineration including energy substitution. Combining an environmentally high or low performing recycling technology with an environmentally high or low performing incineration technology can give quite different results. The modelling showed that recycling of paper, from a life cycle point of view, is environmentally equal or better than incineration with energy recovery only when the recycling technology is at a high environmental performance level. However, the modelling also showed that expanding the system to include substitution of fossil fuel energy by production of energy from the saved biomass associated with recycling will give a completely different result. In this case recycling is always more beneficial than incineration, thus increased recycling is desirable. Expanding the system to include forestry was shown to have a minor effect on the results. As assessments are often performed with a set choice of data and a set recycling rate, it is questionable how useful the results from

    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)

  1. 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

  2. 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

    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.

    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. As for the assessment of the radiological impact of the accelerator to the environment, relevant nuclear reaction cross sections for the activation of the air were recommended among the author's evaluations and existing library based on the available measurements.

    as well. There is not accumulation of source rocks, although some coal beds can be produced during the last stage of palefjord filling. Accumulation at this realm is quite varied, from typical estuarine conditions to slope-complexes generated at the front of braid- and fan-deltas, but there is a high degree of reworking of the deposits due to limited accommodation space and high sediment yield, and as a result sequences are in general much sandier, although their granulometric evolution is similar to that of the internal realm. Two paleofjords were studied in this realm: the Talacasto and Rí San Juan paloefjords. The external realm is characterized by its furthest position with respect to the ice load and as a result the deglacial interval is the thinnest, although due to its distal position, this place has the advantage of recording more previous glacial advances, that were overridden at intermediate and internal positions in the last major glacial advance. At this realm, the postglacial transgression is again quite muddy, as in the internal realm, but in this case, there are no signs of restriction and muds tend to be green, and depleted of organic matter in spite of the rich marine invertebrate fauna, that was not observed at the other sectors. The quantity of wave structures suggest that wave action was much more intense than in the other cases, and in general, there are much less sediments product of gravity flows. We inspected in detail the El Paso and Hoyada Verde paloefjords. This study shows thus, that there is a very important paleogeographic control of depositional processes that have some economic importance. Potential hydrocarbon source rocks would be favored at the inner belt of these palefjords, some doubtful conditions would exist at intermediate positions and basically no source rock would be generated at the outer belt, bear the exits of these paleofjords into the open sea.

    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

    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

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

    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

    Cunha, Burke A; Apostolopoulou, Anna; Gian, John

    Fever of unknown origin (FUO) is defined as prolonged fever of >101 °F for at least 3 weeks that remains undiagnosed after a focused inpatient or outpatient workup. One of the most elusive FUO diagnoses is miliary tuberculosis (TB) which typically has few/no localizing signs/symptoms. Since the introduction of intravesicular Bacille Calmette-Guerin (BCG) treatment for bladder carcinoma, miliary BCG has only rarely been reported as a cause of FUO. As with miliary TB, there are few/no clues to suspect miliary BCG. We present an interesting case of FUO due to miliary BCG without any localizing signs, i.e., no lung, liver or prostate involvement. The only clues to the diagnosis of this FUO due to disseminated BCG were morning temperature spikes and otherwise unexplained highly elevated ferritin levels. Copyright © 2017 Elsevier Inc.

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

    CERN Document Server

    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...

    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.

  18. Technologically important extremophile 16S rRNA sequence Shannon entropy and fractal property comparison with long term dormant microbes

    Technologically important extremophiles including oil eating microbes, uranium and rocket fuel perchlorate reduction microbes, electron producing microbes and electrode electrons feeding microbes were compared in terms of their 16S rRNA sequences, a standard targeted sequence in comparative phylogeny studies. Microbes that were reported to have survived a prolonged dormant duration were also studied. Examples included the recently discovered microbe that survives after 34,000 years in a salty environment while feeding off organic compounds from other trapped dead microbes. Shannon entropy of the 16S rRNA nucleotide composition and fractal dimension of the nucleotide sequence in terms of its atomic number fluctuation analyses suggest a selected range for these extremophiles as compared to other microbes; consistent with the experience of relatively mild evolutionary pressure. However, most of the microbes that have been reported to survive in prolonged dormant duration carry sequences with fractal dimension between 1.995 and 2.005 (N = 10 out of 13). Similar results are observed for halophiles, red-shifted chlorophyll and radiation resistant microbes. The results suggest that prolonged dormant duration, in analogous to high salty or radiation environment, would select high fractal 16S rRNA sequences. Path analysis in structural equation modeling supports a causal relation between entropy and fractal dimension for the studied 16S rRNA sequences (N = 7). Candidate choices for high fractal 16S rRNA microbes could offer protection for prolonged spaceflights. BioBrick gene network manipulation could include extremophile 16S rRNA sequences in synthetic biology and shed more light on exobiology and future colonization in shielded spaceflights. Whether the high fractal 16S rRNA sequences contain an asteroidlike extra-terrestrial source could be speculative but interesting.

    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 present report summarizes the final results of the IAEA Co-ordinated Research Programme on ''Activation Cross Section for the Generator of Long-lived Radionuclides of Importance in Fusion Reactor Technology''. The goal of the CRP was to obtain reliable information (experimental and evaluated) for 16 long-lived activation reactions of special importance to fusion reactor technology. By limiting the scope of the CRP to just 16 reactions it was possible to establish a very effective focus to the joint effort of many laboratories that has led to the generation of a set of valuable new data which provide satisfactory answers to several questions of technological concern to fusion.

    Faillace, C.

    Taking care of thousands of village water supply systems requires a large organization and large financial inputs which most developing countries cannot afford. The author, after having briefly outlined the main points to be considered for the implementation of successful rural water programs, stresses the need to introduce simple, low-cost technologies for supplying safe water to small rural villages. The risk of failure is greatly reduced if there is an active participation of villagers in the various phases of the project. Health education village sanitation and training in the use and repair of equipment are essential for the long life of the water systems.

    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.

    Full Text Available Concept maps have proved to be an efficient tool for learning (Novak & Gowin, 1984 but also without the pretext of making a classification, one could say that has also been found useful to: identify students’ prior knowledge, summarizing what has been learned, note taking, help in the study, plan, build scaffolding for understanding, strengthen educational experiences, improve conditions for effective learning, promote critical thinking, support cooperation and collaboration, organize content (Cañas & Badilla, 2005; Coffey et al., 2003. In this study, we show the opinions concerning the use of Cmap Tools as a tool for making concept maps for their future practice as teachers in primary education, students of second year of teaching at the University of Granada. The research was based on the quantitative perspective, being the instrument used, a questionnaire released by one hand, the students’ opinion on the use of the methodology used: group activity and selfemployment, and the application of the tool Cmap Tools, and collect other personal and academic satisfaction of students involved in this experience. As for the extracted views emphasized that although student teachers feel that using technology in their classes, can be a strategy that promotes the teaching and learning, as claimed on this experience, it is true that students who do not coexist think so, hence it is necessary to strengthen this small percentage use of technological tools in teaching.

    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

    Ferreira, Jose Leonardo; Calvoso, Lui; Gessini, Paolo; Ferreira, Ivan

    Since 2004 The Plasma Physics Laboratory of University of Brasilia (Brazil) is developing Hall Plasma Thurusters for Satellite station keeping and orbit control. The project is supported by CNPq, CAPES, FAP DF and from The Brazillian Space Agency-AEB. The project is part of The UNIESPAÇO Program for Space Activities Development in Brazillian Universities. In this work we are going to present the highlights of this project together with its vital contribution to include University of Brasilia in the Brazillian Space Program. Electric propulsion has already shown, over the years, its great advantages in being used as main and secondary thruster system of several space mission types. Between the many thruster concepts, one that has more tradition in flying real spacecraft is the Hall Effect Thruster (HET). These thrusters, first developed by the USSR in the 1960s, uses, in the traditional design, the radial magnetic field and axial electric field to trap electrons, ionize the gas and accelerate the plasma to therefore generate thrust. In contrast to the usual solution of using electromagnets to generate the magnetic field, the research group of the Plasma Physics Laboratory of University of Brasília has been working to develop new models of HETs that uses combined permanent magnets to generate the necessary magnetic field, with the main objective of saving electric power in the final system design. Since the beginning of this research line it was developed and implemented two prototypes of the Permanent Magnet Hall Thruster (PMHT). The first prototype, called P-HALL1, was successfully tested with the using of many diagnostics instruments, including, RF probe, Langmuir probe, Ion collector and Ion energy analyzer. The second prototype, P-HALL2, is currently under testing, and it’s planned the increasing of the plasma diagnostics and technology analysis, with the inclusion of a thrust balance, mass spectroscopy and Doppler broadening. We are also developing an

    In Cuba post-harvest preservation of onions and garlic for different uses have been performed by irradiation bulbs with a minimal dose range of 80 to 90 Gy of Gamma radiation (Co60 ) at commercial level in the Food Irradiation Plant (PIA) Producto 1 which in 1986 held a nominal activity of 110 000 ci. Results showed that the irradiated products could be preserved up to 8 and 11 months, respectively, resulting un total losses lower than 30 %. Products were stored in a warehouse with forced air distribution system of 22 0C to 32 0C and 70 to 100 % RH, resulting in 30 air changes /hour. An important economic benefit was obtained from this method as compared to other traditional storage methods using controlled temperature chambers ( 1 0C to 3 0C ) to preserve un-irradiated onions an garlic's. It is concluded that the irradiated products could be stored at atmospheric temperature and forced air distribution system resulting in lower losses and energy savings and non-imported product, which to reached more of the 5 dollars millions

    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 relationships of polyunsaturated FAs (PUFA, beneficial for consumer health; 4.53% to MIs were narrower: fat (T, 0.321; P < 0.05; lactose (L, 0.458; P < 0.01; milk alcohol stability (AL, 0.447; P < 0.01; titration acidity (SH, 0.342; P < 0.01; cheese curd quality (KV, 0.427; P < 0.01; milk fermentationability (JSH, 0.529; P < 0.001, streptococci count in yoghurt (Strepto, 0.316; P < 0.05; total count of noble bacteria in yoghurt (CPMUK, 0.314; P < 0.05; streptococci/lactobacilly ratio (StreptoLacto, 0.356; P < 0.01. The relationships of conjugated linoleic acid (CLA; markedly beneficial for health; 0.68% to MIs were: T (0.379; P < 0.01; L (–0.542; P < 0.001; AL (0.266; P < 0.05; KV (0.411; P < 0.01; Strepto (0.260; P < 0.05; StreptoLacto (0.270; 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.

    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. However, the development of fusion power would benefit from an across-the-board refinement in these nuclear data so that a more accurate quantitative

    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.

    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.

    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.

    Decisions on reimbursement of health interventions in many jurisdictions are informed by health technology assessments (HTAs). Historically, the focus of these has often been cost effectiveness or cost utility, while other criteria were considered informally. More recently, there has been an increasing interest in the formal incorporation of additional criteria using multi-criteria decision analysis. Such an approach has not yet formally been part of decision-making policy in Ireland. The objective of this analysis is to demonstrate that cost effectiveness is not the only criterion influencing reimbursement decisions in Ireland. Furthermore, the aim is to reveal criteria that may have informally influenced reimbursement decisions in the past. A list of potential criteria was identified based on the literature, national guidelines and experience of the national HTA agency. Information on each of these criteria was sought for every assessment conducted in Ireland up to July 2015. A logistic regression was fitted to the data to identify influential parameters. Model selection was performed using the Bolasso method. Thirteen criteria were considered in the analysis. Two members of the HTA review team assessed the performance of the interventions against these criteria. Model selection suggests that the incremental cost-effectiveness ratio and quality of evidence could be important drivers of reimbursement recommendations in Ireland. Less important drivers suggested include the year of assessment, the level of uncertainty, as well as safety and tolerability. The analysis demonstrates that recommendations for or against the reimbursement of technologies in Ireland are not only driven by cost effectiveness. This highlights the need for more formal inclusion of criteria in the process, to improve transparency and ensure consistency.

    The purpose of this chapter is to illustrate the importance of using open source technologies and common standards for interoperability when implementing eHealth systems, and to illustrate this through case studies, where possible. The sources used to inform this chapter draw from the implementation and evaluation of the eHealth Program in the context of the Millennium Villages Project (MVP). As the eHealth Team was tasked to deploy an eHealth architecture, the Millennium Villages Global-Network (MVG-Net), across all 14 of the MVP sites in sub-Saharan Africa, the team not only recognized the need for standards and uniformity but also realized that context would be an important factor. Therefore, the team decided to utilize open source solutions. The MVP implementation of MVG-Net provides a model for those looking to implement informatics solutions across disciplines and countries. Furthermore, there are valuable lessons learned that the eHealth community can benefit from. By sharing lessons learned and developing an accessible, open source eHealth platform, we believe that we can more efficiently and rapidly achieve the health-related and collaborative Millennium Development Goals.

    2012-12-01

    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.

    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.

    The Superspeed Maglev System Transrapid is the world's most advanced, track-bound transportation system. Non-contact electromagnetic levitation, guidance and propulsion technology enables operation at high cruising speeds up to 500 km/h with a minimum of wear and tear, low energy consumption and high ride comfort. In order to provide light and stiff components innovative composite structures are used. For the structure of the carriage bodies, a hybrid design using alluminium hollow profiles and alluminium clad foam sandwich panels is chosen. The nose elements are self supporting sandwich structures made from Glass Fibre Reinforced/Polyester resin cladding layers with a foam core. The various structural components are joined using mechanical fixing systems, welding and adhesive bonding. Laser welding is used to secure and seal one of the aluminium cladding sheets to the edging profiles which are integrated into the sandwich panels. The magnet poles as parts of the levitation system are assembled and sealed with resin based on epoxy components. To ensure a high and constant quality standard in the magnet pol production a new process known as automatic pressure gelation is applied. (orig.)

    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.

  1. Due process traditionalism.

    2008-06-01

    In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and they might have joined a cascade. An alternative defense sees due process traditionalism as a second-best substitute for two preferable alternatives: a purely procedural approach to the Due Process Clause, and an approach that gives legislatures the benefit of every reasonable doubt. But it is not clear that in these domains, the first-best approaches are especially attractive; and even if they are, the second-best may be an unacceptably crude substitute. The most plausible defense of due process traditionalism operates on rule-consequentialist grounds, with the suggestion that even if traditions are not great, they are often good, and judges do best if they defer to traditions rather than attempting to specify the content of "liberty" on their own. But the rule-consequentialist defense depends on controversial and probably false assumptions about the likely goodness of traditions and the institutional incapacities of judges.

    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.

    Full Text Available The article explores key issues in reaching a balance of funding resources, needed for fulfilling strategic goals for scientific-technological development ofRussia. Shared forecasts predict that in 2016, Russia's share of the global budget for Research and Development (R&D will amount to less than 2%, whereas the share of only three countries – the USA, China and Japan, will amount to 55,6%. The six leading countries investing heavily state funded in R&D in 2016, will be theUSA,China,Japan,Germany,South KoreaandIndia. The accumulative share of investments in R&D in 2016, will amount to 68,5%. Comparing the investment volumes of leading countries',Russia's expected national investment in R&D might be non-competitive. It is noted that the needed resources for increasing volumes of state funding in Russian scientific-technological field in the midterm perspective are already exhausted. Therefore, the single opportunity for reaching the goal of Russian President's Order № 599 for increasing internal spending on R&D, so it amounts 1,77% of GDP is to dramatically increase the volume of extra-budgetary financing in the domestic R&D sector. Special attention is paid to the disproportion of the budget spending on R&D and the number of people employed in R&D, which leads toRussiahaving one of the lowest indicators among developed countries for «internal expenditure on R&D per researcher». It is concluded that without a clear strategic answer to the posed question about how the Russian industrial sector will be able to increase internal spending on R&D from current 1,15% to 1,77% and how will it accommodate the 4th biggest corpus of scientists in the world in the processes of reindustrialization of the country, strategic targets for becoming a global technological leader risk to remain in the status of «ambitious goals». 

  6. 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.

    No import of biofuels to Sweden for energy production existed before 1991. That year, import of wood chips from Latvia and olive wastes (pits) from the Mediterranean region started, with volumes corresponding to 100 GWh each. This fuels were used in district heating plants, with converted coal boilers. The price was about 120 SEK/MWh (∼ 18 USD/MWh) at the plant. Small amounts of wood pellets were imported from Poland, Canada and Denmark, totalling less than 100 GWh. This fuel was used by small heating centrals and the import was caused by a shortage of swedish pellets. Potentially important export countries, if a large scale biofuel use starts in Sweden, are Russia, the Baltic states, USA, and Canada. Technical possibilities for converting coal-fired boilers to biofuel firing are discussed in a four page section of this paper. (2 refs., 2 tabs.)

    2012-01-01

    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)

    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

    Full Text Available It is not surprising that many business deals fail to realize their expected future value because some deal makers fail to perform effective due diligence. Successful deal makers, however, know that due diligence is one of the most important tasks in successful deal making. Thus, they avoid the psychological and contextual traps that cause poor due diligence. In this article, I describe the hazards – the psychological biases and contextual factors – that might affect the due diligence task. These hazards include information availability bias; confirmation bias; overconfidence bias; time pressure; self-interested agents; deal fever; narrow focus; and complexity. Following this review, I provide a number of suggestions to help deal makers and organizations overcome these hazards.

    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 selection of important outcomes is a crucial decision for clinical research and health technology assessment (HTA), and there is ongoing debate about which stakeholders should be involved. 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. 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. We received completed questionnaires from 49 self-help group patients, 19 nephrologists and 18 HTA authors. Only the following 3 outcomes were ranked within the top 7 outcomes by all 4 groups: safety, HRQoL and emotional state. The ratings by the self-help group were generally more concordant with the reference group ratings than those by nephrologists, while HTA authors showed the least concordance. Preferences of CKD patients from a self-help group, nephrologists and HTA authors differ to a varying extent from those of a large reference group of patients with CKD. The preferences of all stakeholders should form the basis of a transparent approach so as to generate a valid list of important outcomes.

    Most space weather occurs due to solar eruptions (coronal mass ejections (CMEs) and solar flares), which can affect the environment in near-Earth space. Modern society is ever more dependent upon ground-based and spaceborne technology that can be vulnerable to space weather. It is important to have long-running, continuous observations for space-weather forecasting, nowcasting, and research. A meeting organised jointly by the Royal Meteorological Society and Royal Astronomical Society took place at Imperial College, London on 13 November 2013. This public meeting addressed the current deficiency in observations and how this might be overcome.

    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

    A simplified list of the principal Diptera capable of causing myiasis is followed by a brief presentation of the biology, lesions inflicted, and methods of treatment and control of the myiases of economic importance. Cochliomyiasis caused by Cochliomyia hominivorax is of greatest interest, in view of the damage and losses caused by this disease. A brief account of the outbreak of infestation in Libya illustrates the danger of this parasite. Other important traumatic myiases are described: that due to Chrysomya bezziana, which causes an African myiasis similar to cochliomyiasis, and those due to Lucilia cuprina and related species. Hypodermyiasis (warble fly infestation) and oestrosis (nasal bot fly infestation in sheep) still cause major economic losses in domestic animals, justifying their inclusion in control campaigns. The same applies to stomach bot flies of the family Gasterophilidae. The account of each myiasis includes notes on parasiticides which have been found to be effective. Given the rapidity with which a parasite can now be transported from one continent to another, it is important for Veterinary Services to be well-informed and vigilant.

    Free-living amebae appertaining to the genus Acanthamoeba, Naegleria and Balamuthia are the most prevalent protozoa found in the environment. These amebae have a cosmopolitan distribution in soil, air and water, providing multiple opportunities for contacts with humans and animals, although they only occasionally cause disease. Acanthamoeba spp. are the causative agent of granulomatous amebic encephalitis, a rare and often fatal disease of the central nervous system, and amebic keratitis, a painful disease of the eyes. Keratitis usually follows a chronic course due to the delay in diagnosis and subsequent treatment. The clear increase in Acanthamoeba keratitis in the last 20 years is related to the use and deficient maintenance of contact lenses, and to swimming while wearing them. The expected incidence is one case per 30,000 contact lens wearers per year, with 88% of cases occurring in persons wearing hydrogel lenses. This review presents information on the morphology, life-cycle and epidemiology of Acanthamoeba, as well as on diagnostic procedures (culture), appropriate antimicrobial therapy, and prevention measures.

    2012-12-01

    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.

    The development and application of new technologies in the United States has always been important to the economic well being of the country. The National Aeronautics and Space Administration (NASA) has been an important source of these new technologies for almost four decades. Recently, increasing global competition has emphasized the importance of fully utilizing federally funded technologies. Today NASA must meet its mission goals while at the same time, conduct research and development that contributes to securing US economic growth. NASA technologies must be quickly and effectively transferred into commercial products. In order to accomplish this task, NASA has formulated a new way of doing business with the private sector. Emphasis is placed on forming mutually beneficial partnerships between NASA and US industry. New standards have been set in response to the process that increase effectiveness, efficiency, and timely customer response. This summer I have identified potential markets for two NASA inventions: including the Radially Focused Eddy Current Sensor for Characterization of Flaws in Metallic Tubing and the Radiographic Moire. I have also worked to establish a cooperative program with TAG, private industry, and a university known as the TAG/Industry/Academia Program.

    At present, the development of high technology has opened a new chapter in world's history of science and technology. This review describes the great impact of physics on high technology in six different fields (energy technology, new materials, information technology, biotechnology, space technology, and Ocean technology). It is shown that the new concepts and new methods created in physics and the special conditions and measurements established for physics researches not only deepen human's knowledge about nature but also point out new directions for engineering and technology. The achievements in physics have been more and more applied to high technology, while the development of high technology has explored some new research areas and raised many novel, important projects for physics. Therefore, it is important for us to strengthen the research on these major problems in physics

    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

  4. Import, Offshoring and Wages

    DEFF Research Database (Denmark)

    Fosse, Henrik Barslund; Maitra, Madhura

    Offshoring firms are found to pay higher average wages than purely domestic firms. We provide a unifying empirical approach by capturing the different channels through which offshoring may explain this wage difference: (i) due to change in the composition of workers (skill composition effect) (ii...... of skill composition and rent sharing available in typical firm level datasets - like ratio of educated to uneducated workers and sales per employee.......) because all existing workers get higher pay (rent sharing effect). Using Danish worker-firm data we explain how much each channel contributes to higher wages. To estimate the causal effect of offshoring on wages we use China’s accession to the WTO in December 2001 - and the soon after boom in Chinese...... exports - as positive exogenous shocks to the incentive to offshore to China. Both skill composition and rent sharing effects are found to be important in explaining the resultant gain in wages. We also show that the firm’s timing in the offshoring process determines the relative importance of a channel...

    We describe the current state-of-the-art in Trusted Computing Technologies - focusing mainly on Intel's Trusted Execution Technology (TXT). 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.

    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

    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

  18. Fundamentals of technology roadmapping

    Garcia, M.L.; Bray, O.H.

    1997-04-01

    Technology planning is important for many reasons. Globally, companies are facing many competitive problems. Technology roadmapping, a form of technology planning can help deal with this increasingly competitive environment. While it has been used by some companies and industries, the focus has always been on the technology roadmap as a product, not on the process. This report focuses on formalizing the process so that it can be more broadly and easily used. As a DOE national security laboratory with R&D as a major product, Sandia must do effective technology planning to identify and develop the technologies required to meet its national security mission. Once identified, technology enhancements or new technologies may be developed internally or collaboratively with external partners. For either approach, technology roadmapping, as described in this report, is an effective tool for technology planning and coordination, which fits within a broader set of planning activities. This report, the second in a series on technology roadmapping, develops and documents this technology roadmapping process, which can be used by Sandia, other national labs, universities, and industry. The main benefit of technology roadmapping is that it provides information to make better technology investment decisions by identifying critical technologies and technology gaps and identifying ways to leverage R&D investments. It can also be used as a marketing tool. Technology roadmapping is critical when the technology investment decision is not straight forward. This occurs when it is not clear which alternative to pursue, how quickly the technology is needed, or when there is a need to coordinate the development of multiple technologies. The technology roadmapping process consists of three phases - preliminary activity, development of the technology roadmap, and follow-up activity.

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. 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. Eight patents were deposited during 2004

    Technology transfer of biological products is a complex process that is important for product commercialization. To achieve a successful technology transfer, the risks that arise from changes throughout the project must be managed. Iterative risk analysis and mitigation tools can be used to both evaluate and reduce risk. The technology transfer stage gate model is used as an example tool to help manage risks derived from both designed process change and unplanned changes that arise due to unforeseen circumstances. The strategy of risk assessment for a change can be tailored to the type of change. In addition, a cross-functional team and centralized documentation helps maximize risk management efficiency to achieve a successful technology transfer. © PDA, Inc. 2016.

    Three cases are reported of the pseudotumour cerebri syndrome-that is, intracranial hypertension without mass lesion or enlarged ventricles, due to cryptococcal meningitis. In these patients the papilloedema was successfully treated with optic nerve sheath decompression, and the intracranial hypertension with lumboperitoneal CSF shunting. These cases support the concept that pseudotumour cerebri is a syndrome of intracranial hypertension that can be due to any disorder producing obstruction of the CSF pathways at the level of the arachnoid villi. This concept is important because it directs therapy to normalise the intracranial pressure and preserve vision. Images PMID:9010409

    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.

    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...

    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.

    The study of networks in the form of mathematical graph theory is one of the fundamental pillars of discrete mathematics. However, recent years have witnessed a substantial new movement in network research. The focus of the research is shifting away from the analysis of small graphs and the properties of individual vertices or edges to consideration of statistical properties of large scale networks. This new approach has been driven largely by the availability of technological networks like the Internet [12], World Wide Web network [2], etc. that allow us to gather and analyze data on a scale far larger than previously possible. At the same time, technological networks have evolved as a socio-technological system, as the concepts of social systems that are based on self-organization theory have become unified in technological networks [13]. In today’s society, we have a simple and universal access to great amounts of information and services. These information services are based upon the infrastructure of the Internet and the World Wide Web. The Internet is the system composed of ‘computers’ connected by cables or some other form of physical connections. Over this physical network, it is possible to exchange e-mails, transfer files, etc. On the other hand, the World Wide Web (commonly shortened to the Web) is a system of interlinked hypertext documents accessed via the Internet where nodes represent web pages and links represent hyperlinks between the pages. Peer-to-peer (P2P) networks [26] also have recently become a popular medium through which huge amounts of data can be shared. P2P file sharing systems, where files are searched and downloaded among peers without the help of central servers, have emerged as a major component of Internet traffic. An important advantage in P2P networks is that all clients provide resources, including bandwidth, storage space, and computing power. In this chapter, we discuss these technological networks in detail. The review

    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.

    1982-06-22

    The injection of waters that are not native to a geothermal formation generates various physical and chemical problems. The major chemical problem resulting from such injections is the formation of sulfate scales (particularly CaSO4, BaSO4 and SrSO4) at various locations starting from the injection well through the production well to the surface facilities of any geothermal operation. One of the ways to prevent this type of scale formation is by reducing the sulfate concentration of the injection waters. The effect of sulfate deionization on scale formation at various locations of the geothermal operations is studied. Some experimental results on the CaSO4 scale formation in porous media upon heating an injection water with and without addition of scale inhibitors are also given.

    2017-01-01

    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

  9. Uses of risk importance measures

    International Nuclear Information System (INIS)

    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

    Full Text Available Introduction: Systemic contact dermatitis (SCD is a systemic reactivation of a previous allergic contact dermatitis. The initial exposure may usually be topical, followed by oral, intravenous or inhalation exposure leading to a systemic hypersensitivity reaction. A case of a 27 year-old male with SCD due to nickel is reported Case Report: A 27 year-old male presented with recurrent pruritic eruption consist of deep seated vesicles on both palmar and left plantar since 6 months before admission. This complaint began after patient consumed excessive amounts of chocolate, canned food, and beans. The patient worked as a technician in a food factory. History of allergy due to nickel was acknowledged since childhood. The clinical presentation was diffuse deep seated vesicles, and multiple erythematous macules to plaques, with collarette scale. Patch test using the European standard showed a +3 result to nickel. The patient was diagnosed as systemic contact dermatitis due to nickel. The treatments were topical corticosteroid and patient education of avoidance of both contact and systemic exposure to nickel. The patient showed clinical improvement after 2 weeks. Discussion: SCD was diagnosed due to the history of massive consumption of food containing nickel in a patient who had initial sensitization to nickel, with clinical features and the patch test result. Advice to be aware of nickel and its avoidance is important in SCD management.

  16. 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 dose due to {sup 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 {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)

    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.

    Shear flow is the most important ingredient governing nonlinear behavior of many types of plasma instability. Electromagnetic effects on shear flow generation have been studied for an electro- magnetic drift wave called resistive drift-Alfven mode (RDAM) and a global MHD mode called resistive wall mode (RWM). For RDAM it is found that the generated shear flow stabilizes the dominant modes; however, other modes are destabilized. For RWM Maxwell stress due to magnetic fluctuations has a tendency to suppress the poloidal flow near the plasma surface, which gives almost same saturation level, since the shear flow stabilization disappears.

    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

    The overall objective of the Ramsar convention is the conservation and wise use of wetlands by national actions and international cooperation as a means to achieving sustainable development. This complex and challenging task requires national, local and international bodies involved in the implementation of the convention to rely on suitable geo-information in order to better understand wetland areas, complete national inventories, perform monitoring activities, carry out assessments and put in practice suitable management plans based on up to date and reliable information. In the recent years, the use of satellite earth observations (EO) within innovative geo-spatial analysis has revealed to be a key tool and unique information source to support the environmental community in different application domains, including wetlands conservation and management. The paper presents the main results and findings of the GlobWetland I project, providing an overview of the current capabilities and limits of EO technology as a tool to support the implementation of the Ramsar convention. It also summarises the major recommendations of the GlobWetland symposium "GlobWetland: Looking at Wetlands from Space" which principal aim was to strengthen the links between the different actors involved in the implementation of the Ramsar convention, and the earth observation community, in order to review the state of the art in the use of EO technology for wetlands management. Finally it presents the objective and scope of the GlobWetland II project, which will contribute to the establishment of a Global Wetlands Observing System (G-WOS) in accordance with the Strategic Plan 2009-2015 of the Ramsar convention on wetlands adopted as the last Conference of the Parties.

    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)

    2009-01-01

    Full Text Available Board of Radiation and Isotope Technology, a unit of the Department of Atomic Energy, fabricates and supplies radioactive sources for medical, industrial, agriculture and research applications. High specific activity cobalt-60, required for teletherapy is normally imported. There was a proposal for manufacturing high specific activity sources indigenously. A study was carried out to observe the feasibility of mixing imported and indigenous cobalt-60 pellets to fabricate teletherapy source capsules. The specific activity of imported pellets is more than 300 Ci/g, whereas that of indigenous pellets obtained from Indian power reactors is 140 Ci/g. The radiation output from a capsule for different combinations of specific activity was evaluated. Losses due to self-absorption were accounted in the evaluations. In another study, the optimized lengths of the capsule for an output of 200 RMM and the additional activity to be added to compensate losses due to self-absorption were also estimated for different specific activity pellets. Sources fabricated on the basis of this study showed a good agreement with the estimations. Source capsules with a combination of different specific activities are yet to be fabricated.

    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)

    Mycobacterium simiae is a slow-growing photochromogenic environmental mycobacterium, first described in 1965. Rarely associated with human infections, possibly due to its limited pathogenicity, it mainly produces lung infection in immunocompetent elderly patients with underlying lung disease, and in disseminated infections in immunosuppressed young patients with AIDS. A microbiological culture is needed to confirm the clinical suspicion, and genetic sequencing techniques are essential to correctly identify the species. Treating M. simiae infections is complicated, owing to the multiple resistance to tuberculous drugs and the lack of correlation between in vitro susceptibility data and in vivo response. Proper treatment is yet to be defined, but must include clarithromycin combined with other antimicrobials such as moxifloxacin and cotrimoxazole. It is possible that M. simiae infections are undiagnosed. Copyright © 2013 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica. All rights reserved.

    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.

    2012-10-01

    Dry ice is a commercially available cryogen that is used worldwide. It may cause frostbite if misused. However, frostbite of the oral cavity due to dry ice has not been previously reported. Here, we describe the first case of dry ice-induced frostbite of the oral cavity. We present a case of oral frostbite due to dry ice and subsequent swelling of the submandibular area and lower lip. We discuss the clinical features of oral frostbite due to volatile substance abuse. Oral frostbite not only may result in the impairment of the affected mucosae directly, but also may adversely affect the tissues in the vicinity of the oral cavity floor indirectly. Oral frostbite may cause edema of the upper airway tract. In case of severe pharyngolaryngeal edema, either tracheal intubation or tracheostomy is necessary. Steroids and antibiotics may be effective in preventing the development of pharyngolaryngeal edema. It is important to bear in mind that volatile substance abuse may possibly induce unusual events. In particular, special attention should be paid to delayed unusual events.

    The use of artificial nails (ANs) as part of nail-care cosmetics is very popular. Several side effects and complications, such as contact dermatitis and bacterial and fungal infections, have been reported in patients using ANs. Objective The purpose of this study was to identify the fungal pathogens in nail abnormalities appearing in patients with ANs. We evaluated 68 patients suffering from nail changes and paronychia, which appear after removal of ANs. Mycological samples were obtained from two sites: distal parts of the involved nail and the proximal nail fold. KOH examination and fungal culture were used for detection and identification of fungal infection. Mycological results from the distal part of the nail showed positive KOH test in 57 cases (83.8%), and culture was positive in 67 patients (98.5%). Mycological results obtained from the proximal nail fold showed positive KOH test in 36 patients (52.9%); in 36 of the cases, culture was positive. Candida spp. were the most common pathogen. Both KOH and culture results were significantly better while sampling from the distal part of the nail compared with sampling from the proximal nail fold (P = 0.0001). Onychomycosis was found to be very common in nail changes due to ANs, leading to an increased risk of transmitting microbial infections. Therefore, health care personnel and workers in the food industry should avoid using ANs.

    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.

    The benefits and disadvantages for Ontario in exporting hydro electricity from Manitoba were discussed. Manitoba Hydro is already a major exporter of electricity to the United States. A history of Manitoba-Ontario electricity transactions was provided. There are currently 5,000 MW of developable hydro in Manitoba. A map of potential transmission routes was presented and transmission costs were discussed along with reliability and security issues. Benefits of a large hydro purchase from Manitoba were considered to be: long term source of supply; predetermined prices; no air emissions; proven technology; a balanced portfolio; and, a high dispatch capability. In addition, the fact that hydro is a low impact, renewable energy source was considered to be beneficial. Case studies were provided with comparisons of other energy sources. Factors that should be considered in determining trade relations between the two provinces include long lived assets with a minimum 20 year contract; the potential to reduce emissions in Ontario; and, the fact that the regulatory process is long and uncertain. It was noted that it is currently easier to get approval for a coal-fired power plant than for low emission hydro. tabs., figs

    2013-01-01

    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.

    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.

  2. 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.

    1995-04-01

    The developments in apheresis techniques and their clinical applications world-wide are technologically driven. In the past, apheresis survey statistics have high-lighted both the differences by region in clinical practice and in the types of technologies utilized. Such differences have provided a basis for the scientific and clinical assessments of these apheresis technologies and their clinical outcomes and have stimulated the marketing and business development of new technologies world-wide. A review of the regional practices and technologies utilized provides a perspective on the future role of apheresis and its developments in clinical practice. While technology is a driving force for the development of new techniques for clinical practice, it is not the only market force. For technology introduction, several other important issues need to be considered. Regulations at the local and, most importantly, the federal level impact the timing for new technology introduction. Reimbursement by healthcare payers is critically important from the initiation of the development of a technology through its clinical use. Clinical trials are critically important to show the safety and clinical- and cost-effectiveness of the technology in order for payers to provide reimbursement for its use, but these trials are sometimes long and costly. Research funding availability at the governmental and commercial levels critically impacts new technology investigation and its introduction. Apheresis technology developments offer new hopes and promises for the clinical team; however, their development, introduction, and utilization will be influenced by the prevailing market forces.

  5. Review of synergisms in materials erosion due to multispecies impact

    International Nuclear Information System (INIS)

    Haasz, A.A.; Auciello, O.; Stangeby, P.C.

    1985-05-01

    Plasma-surface interaction phenomena have become a subject of major interest because of their relevance in two important technological developments of recent decades, viz, microelectronics and thermonuclear fusion. Microelectronic fabrication often involves the use of relatively low-pressure/low-temperature plasma discharges for etching micron-size features in integrated circuits; here erosion is a desired effect. Fusion plasmas, by contrast, cause erosion of the fusion device inner walls, which is generally not desirable. In both cases surfaces are bombarded simultaneously by plasma species which include ions, neutral atoms, electrons and photons, which might lead to enhanced erosion due to synergistic effects. Work performed to date suggests that similar chemistry may be involved in the erosion process associated with some semiconductor and fusion related materials: SiF 4 , SiCl 4 and CH 4 , are, for example, some of the principal species evolving from Si and C surfaces, when exposed to F, Cl and H atoms, respectively, causing the observed erosion. Considerable effort has been expended on studies involving synergistic effects for semiconductor fabrication. Research on synergism related to the erosion of fusion materials (C and carbon compounds) commenced comparatively recently; however, its importance has been increasingly recognized, and evidence of possible synergistic erosion of graphite has recently been obtained in the PLT fusion device. In light of the the interdisciplinary nature of the subject, experimental and theoretical work on synergistic effects in erosion of both semiconductors and fusion materials will be critically reviewed here in an attempt to unify concepts related to results and mechanisms proposed to explain the observed phenomena, and to explore possible new avenues of research. 128 refs

    1986-01-01

    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.

    Estrada, J.

    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.

    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

    The most suitable kinetic energy range of ionized materials in film formation and epitaxial growth is from a few eV to a few hundreds eV, especially, less than about 100eV, when ions are used as a host. The main roles of ions in film formation are the effects due to their kinetic energy and the electronic charge effects which involve the effect to active film formation and the effect acceleration of chemical reactions. Therefore, it is important to develope the technology to transport large volume of a flux of ionized particles with an extremely low incident energy without any troubles due to the space charge effects and charge up problems on the surface. This is the exact motivation for us to have been developing the Ionized Cluster Beam (ICB) technology since 1972. By ICB technology materials (actually wide varieties of materials such as metal, semiconductor, magnetic material, insulator, organic material, etc.) are vaporized and ejected through a small hole nozzle into a high vacuum, where the vaporized material condenses into clusters with loosely coupled atoms with the sizes about from 100 to a few 1000 atoms (mainly 100-2000 atoms) by supercondensation phenomena due to the adiabatic expansion in this evaporation process through a small hole nozzle. In the ICB technology an atom in each cluster is ionized by irradiated by electron shower, and the ionized clusters are accelerated by electric field onto a substrate. The ionized clusters with neutral clusters impinged onto a substrate are spreaded separately into atoms migrating over the substrate, so that the surface migration energy of the impinged atoms, that is, surface diffusion energy are controlled by an incident energy of a cluster. In this report the theoretical and also experimental results of ICB technology are summarized

    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

    The role of technology in the cost of health care is a primary issue in current debates concerning national health care reform. The broad scope of studies for understanding technological impacts is known as technology assessment. Technology policy makers can improve their decision making by becoming more aware, and taking greater advantage, of key trends in health care technology assessment (HCTA). HCTA is the systematic evaluation of the properties, impacts, and other attributes of health care technologies, including: technical performance; clinical safety and efficacy/effectiveness; cost-effectiveness and other economic attributes; appropriate circumstances/indications for use; and social, legal, ethical, and political impacts. The main purpose of HCTA is to inform technology-related policy making in health care. Among the important trends in HCTA are: (1) proliferation of HCTA groups in the public and private sectors; (2) higher standards for scientific evidence concerning technologies; (3) methodological development in cost analyses, health-related quality of life measurement, and consolidation of available scientific evidence (e.g., meta-analysis); (4) emphasis on improved data on how well technologies work in routine practice and for traditionally under-represented patient groups; (5) development of priority-setting methods; (6) greater reliance on medical informatics to support and disseminate HCTA findings.

  13. Traditions of technology

    1979-01-01

    Modern technology, with about 300 years of history behind it, has become the dominant tradition by marginalizing the other traditions of technology in the West and in the rest of the world. Important roles have been played in this marginalization by the ideology of Englightenment, by the Industrial Revolution, and nineteenth and twentieth century colonialism. They have blurred the difference between science and technology, underwritten the mechanomorphic world-image and promoted the concept of a value-free, ethically unrestrained technology. However, the present crises of technological consciousness has brought to the fore alternative traditions of technology, not as ethnotechnologies from which a universal, secular, modern technology can draw lessons, but as a competing philosophies of universality which can provide correctives to the alienating, exploitative, and dehumanizing role of modern science and technology. An alternative ideology of science is needed for this as well as a new legitimacy for the traditional technosystems and their cultural environments. Such a legitimacy will have to be based on a different set of values relating to the man--nature and man--man relationships and a deeper understanding of the politics of technology in its cross-national and cross-cultural contexts.

    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

    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.

    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.

    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.)

However, the current accelerated pace of new food production is due to the rapid incorporation of biotechnological techniques that allow the rapid identification of new molecules and microorganisms or even the genetic improvement of known species. At no other time in history have microorganisms been so present in areas such as agriculture and medicine, except as recognized villains. Currently, however, beneficial microorganisms such as plant growth promoters and phytopathogen controllers are required by various agricultural crops, and many species are being used as biofactories of important pharmacological molecules. The use of biofactories does not end there: microorganisms have been explored for the synthesis of diverse chemicals, fuel molecules, and industrial polymers, and strains environmentally important due to their biodecomposing or biosorption capacity have gained interest in research laboratories and in industrial activities.

    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

    In human lives, technology holds sway in mundane and extraordinary ways, such as in the ways we work, entertain, transport, and feed ourselves, and importantly in the ways we encounter and manage health, disease, illness, and death. A significant area of Heidegger's later work is questioning technology. Unlike many current inquiries that centre on contemporary technology's function, utility, and positive transformations, Heidegger offers a radical way of thinking about technology through developing an inquiry that uncovers technology's essence of revealing. In this article, Heidegger's thinking about technological modes of revealing in regard to bodies, health, and illness is explored. In Heidegger's view, the ordered revealing of modern technology has overshadowed other modes of revealing. This article highlights how remembering concealment and unconcealment in its many modes can be relevant to nurses and others involved in health care. Through tracing Heidegger's thinking about technology, a more critical approach to the effects and outcomes of modern technologies within health care systems can be generated.

    Research scope: The scope of the project is to study technological implementation processes by using Weick's sensemaking concept (Weick, 1995). The purpose of using a social constructivist approach to investigate technological implementation processes is to find out how new technologies transform...... patterns of social action and interaction in organisations (Barley 1986; 1990, Orlikowski 2000). Current research in the field shows that new technologies affect organisational routines/structures/social relationships/power relations/dependencies and alter organisational roles (Barley 1986; 1990, Burkhardt......, Orlikowski 2000). Viewing the use of technology as a process of enactment opens up for investigating the social processes of interpreting new technology into the organisation (Orlikowski 2000). The scope of the PhD project will therefore be to gain a deeper understanding of how the enactment of new...

    Technology, which is older than science, has been of vital importance in the development of modern medicine. Even so, there are voices of dissent to be heard. The disenchantment with technology expressed by Aldous Huxley in Brave new world has been echoed by contemporary writers on the technology of modern medicine. Medicine is seen by some to have been dehumanized by technology, and techniques that are expensive are thought to be consuming a greater proportion of health resources than they deserve. The practice of medicine has, nevertheless, been transformed by modern technology and diagnostic techniques and therapeutic measures undreamed of a few short decades ago are now commonplace. There is no reason why these developments should be any more dehumanizing than the use of similar techniques in modern transportation or communication, nor is their expense out of proportion when compared with other demands on the nation's purse. British workers have been at the forefront of many recent advances. Yet, even though the National Health Service provides a ready market for the products of British medical technology, the nation depends to an inordinate degree on imported products. In the development of appropriate medical technology there is an urgent need for better communication between inventors, scientists, industrialists and the National Health Service. At the same time there is an equal need for improved evaluation of untried techniques. The pressure for a central integrating body to coordinate resources could well be supported by the establishment of evaluation units in the different health authorities in this country.

    2016-12-01

    While healthcare entities have integrated various forms of health information technology (HIT) into their systems due to claims of increased quality and decreased costs, as well as various incentives, there is little available information about which applications of HIT are actually the most beneficial and efficient. In this study, we aim to assist administrators in understanding the characteristics of top performing hospitals. We utilized data from the Health Information and Management Systems Society and the Center for Medicare and Medicaid to assess 1039 hospitals. Inputs considered were full time equivalents, hospital size, and technology inputs. Technology inputs included personal health records (PHR), electronic medical records (EMRs), computerized physician order entry systems (CPOEs), and electronic access to diagnostic results. Output variables were measures of quality, hospital readmission and mortality rate. The analysis was conducted in a two-stage methodology: Data Envelopment Analysis (DEA) and Automatic Interaction Detector Analysis (AID), decision tree regression (DTreg). Overall, we found that electronic access to diagnostic results systems was the most influential technological characteristics; however organizational characteristics were more important than technological inputs. Hospitals that had the highest levels of quality indicated no excess in the use of technology input, averaging one use of a technology component. This study indicates that prudent consideration of organizational characteristics and technology is needed before investing in innovative programs.

  13. New Technologies for Detection of Enteric Parasites.

    Science.gov (United States)

    Ryan, Una; Paparini, Andrea; Oskam, Charlotte

    2017-07-01

    Enteric parasites are major contributors to the global diarrhoeal disease load, infecting >67.2 million people. Their prevalence and clinical impact, however, are underestimated due to lack of adequate detection, which is largely still based on microscopy, particularly in developing countries. New commercially available enteric panel assays, which detect parasites (as well as bacteria and/or viruses) using multiplex PCR, offer enhanced sensitivity and specificity as well as the ability to detect mixed infections, and will play an important role in epidemiological surveillance and outbreak investigations. A major limitation of these technologies, however, particularly for developing countries, is the costs involved. Emerging technologies for low-resource, point-of-care (POC) settings have the potential to dramatically improve the cost and accuracy of enteric parasite detection in the future.

    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.

    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.

    2013-11-01

    Full Text Available New technologies are changing how and when we learn about events and choose to respond to them. Mobile phones and the internet have altered how we engage with the world. With technology usage expanding rapidly in the developing world, new avenues of participation, engagement, and accountability are emerging. Globally, more people now have the opportunity to actively make use of these tools to participate in processes that impact their societies. This opportunity for participation is also an opportunity for engaging in new ways with peacebuilding processes. As the field of technology for peacebuilding grows, most attention has been paid to the potential of new technologies for bridging the gap between warning and response. Whilst the focus on the use of technology for early warning and response is important, there is more to this growing field. The empowerment of people to participate in localized conflict management efforts is one of the most significant innovations and opportunities created by new technologies. Technology can contribute to peacebuilding processes by offering tools that foster collaboration, transform attitudes, and give a stronger voice to communities. This article aims to give practitioners two related frameworks to understand how new technologies can enhance peacebuilding. The first section looks at the functions that technology can have in a peacebuilding program as a tool for data processing, communication, engagement, and gaming. We then examine the program areas that new technologies can best contribute to, covering early warning/early response systems, programs that allow citizens to voice their opinions and experiences, collaboration efforts, and programs aimed at transforming attitudes.

    In the recent decade the concept of active aging has become important in the Western hemisphere. The World Health Organization and The European Union have staged active aging as a core policy area and initiated programs of physical activity, independence and prolonged working lives among...... the elderly. As part of this rearticulation of old age, many new technologies take form. This paper uses a wide concept of technologies (devices, regimes, strategies and ways of doing) and argues that technologies form active aging subjectivities, and on the other hand, that these subjectivities...... in their socio-material practices form active aging. Hence, active aging is a mutual entanglement (Callon and Rabeharisoa 2004) between technologies, practices and subjectivities. The paper is based on four months of participant observations and 17 in-depth interviews with elderly persons conducted at three...

    Throughout the summer of 2004, I am working on a number of different projects. While located in the Space Power and Propulsion Test Engineering branch, my main area of study is flywheel technology. I have been exposed to flywheels, their components, and their uses in today's society. I have been able to experience numerous flywheels here in the flywheel lab at NASA Glenn. My first main project was to explore the attributes and physical characteristics of a flywheel. Our branch was constructing a flywheel demonstration to be presented at the public open house taking place in June. Our Flywheel Interactive Demo, or FIDO, represents a real life multi-flywheel system here at NASA. I was given the opportunity to learn about how these flywheels store energy and are able to position a satellite. With all of this new knowledge, I was able to create the posters that explained how our demonstration worked. I also composed a step-by-step process made up of four experiments that any visitor could follow and perform on FIDO. By stepping through these experiments, the individual learns how a flywheel works. They not only read the explanation of what is happening, but they are also able to see it happen. Creating these two posters not only taught me, but also helped teach the general public during the open house, how flywheel technology is a very important part of our future. Through my research, I have learned that flywheels are able to store massive amounts of energy. They can be described as an electro-mechanical battery that stores kinetic energy while rotating. The faster it rotates, the more energy it stores. Their lifetime is about triple that of an ordinary battery. Flywheels also have the ability to combine energy storage with attitude control all in a single system. Attitude control is the ability to position a satellite as required. FIDO helps us to understand the rotational force (torque) that is applied upon a turn-table or satellite during wheel acceleration

    2014-10-01

    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.

The diffusion coefficient is described in terms of a form factor which consists of three portions; the wave number and frequency spectra of density fluctuations, the effect of longitudinal wave-particle interaction, and the transverse dispersion function. The transverse dispersion gives the plasma skin depth as the characteristic scale length, which yields the Alcator-like scaling of the diffusion coefficient. The form factor shows a resonance-like behavior due to the magnetic part of fluctuations at the drift frequency, which indicates the importance of density fluctuations near the frequency in the electromagnetic plasma turbulence. This resonance is enhanced with increasing the plasma pressure, and finally the transition of the Alcator scaling is possible in the case of narrow band turbulence. The transitions of the Alcator scaling by the effect of collision is also derived in the single mode approximation. (author)

    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.

  1. Epileptic seizures due to multiple cerebral cavernomatosis

    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. .

    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.

  6. 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.

All these changes create the potential for serious, perhaps unintended, consequences for the economic future of the country. In a paper entitled, 'A Conceptual Framework for Evaluating the Impact of Changes in Federal Support for Science and Technology,' we introduce a model to evaluate the effects of changes in federal spending for science and technology. This paper both provides a way of organizing informed discussions and points out important research topics for science and technology policy.

  8. COPPER CABLE RECYCLING TECHNOLOGY

    International Nuclear Information System (INIS)

    Chelsea Hubbard

    2001-01-01

    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

  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

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

    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.

    1979-01-01

    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).

    Full Text Available Formulation of the problem. This article contains information about the methods and the planning principles used in experimental research study of the injection technology of impervious screen. Today, there are ways to create impervious screens and curtains solve soil protection issues in the field impermeable layer arrangement at a shallow depth. 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.

    Moosa, Ebrahim

    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.

    A process is underway to develop mature, integrated methodologies to address nonproliferation issues. A variety of methodologies (both qualitative and quantitative) are being considered. All have one thing in common, a need for a consistent set of proliferation related data that can be used as a basis for application. One approach to providing a basis for predicting and evaluating future proliferation events is to understand past proliferation events, that is, the different paths that have actually been taken to acquire or attempt to acquire special nuclear material. In order to provide this information, this report describing previous material acquisition activities (obtained from open source material) has been prepared. This report describes how, based on an evaluation of historical trends in nuclear technology development, conclusions can be reached concerning: (1) The length of time it takes to acquire a technology; (2) The length of time it takes for production of special nuclear material to begin; and (3) The type of approaches taken for acquiring the technology. In addition to examining time constants, the report is intended to provide information that could be used to support the use of the different non-proliferation analysis methodologies. Accordingly, each section includes: (1) Technology description; (2) Technology origin; (3) Basic theory; (4) Important components/materials; (5) Technology development; (6) Technological difficulties involved in use; (7) Changes/improvements in technology; (8) Countries that have used/attempted to use the technology; (9) Technology Information; (10) Acquisition approaches; (11) Time constants for technology development; and (12) Required Concurrent Technologies.

    Advanced technology offers significant potential benefit to the nuclear industry. Improvements can be anticipated in plant performance, reliability, and overall plant safety as well as reduced life cycle costs. Utilizing artificial intelligence and expert systems, robotics, advanced instruments and controls, and modularization technologies can enhance plant operations and provide new insights and perspectives to plant risk and thus focus resources to areas of importance. Plant reliability, operability, availability, accident interdiction and limitation, and plant recovery are expected to improve. However, utilizing these technologies is not an automatic process. In addition to the actual costs associated with developing and implementing the technologies, operator training and acceptance represents a potential significant problem. Traditional plant operators have little or no experience with computer technology. There has already been some difficulty getting nuclear plant operators to accept and use the new technologies that have been implemented to accept and use the new technologies that have been implemented thus far

    Middleton, C.D.

    2004-01-01

    This paper focuses on the role of non-governmental organization (NGO) citizen groups in Ontario in the use and production of electricity. NGOs have the potential to act both directly on their own accord, and indirectly by pressuring government and others. Current demand for electricity is divided between industrial, commercial and residential users. Citizens have an important role to play in reducing energy demand. On the supply side, there is a revival of interest in renewable energy based on wind, photovoltaic and local-hydro technologies as a result of the escalating environmental and economic costs of coal and nuclear generation. However, citizen groups have greater interest and enthusiasm than technical expertise, creating a mismatch between technological solutions and human need or use of them. This paper discusses how this mismatch applies to renewable-energy technologies, many of which are not especially user-friendly, or accessible. While alternative technologies are increasingly welcomed by government, industry is developing a large and growing array of technological devices. In between this is the citizen, who, despite keen interest, can be overwhelmed by the complexity of the situation. This paper links the theoretical perspective to the real world with a discussion of the dynamics between people and renewable energy in citizen groups and makes particular reference to one group, Citizens for Renewable Energy, that has been making renewable energy technology more accessible to its members for over a decade

    Gabriela Carneiro C. Fortes

    Full Text Available ABSTRACT Rapidly progressive dementia (RPD is typically defined as a cognitive decline progressing to severe impairment in less than 1-2 years, typically within weeks or months. Accurate and prompt diagnosis is important because many conditions causing RPD are treatable. Neurosarcoidosis is often cited as an unusual reversible cause of RPD. Methods: We report two cases of neurosarcoidosis presenting as RPD. Results: Case 1: A 61-year-old woman developed a RPD associated with visual loss. In seven months she was dependent for self-care. Magnetic resonance imaging (MRI revealed temporal and suprasellar brain lesions. Treatment with high-dose intravenous prednisolone was associated with partial improvement. Case 2: A 43-year-old woman who was being treated for diabetes insipidus developed a severe episodic amnesia one year after onset of cognitive symptoms. Previous MRI had shown a hypothalamic lesion and she had been treated with oral prednisone and cyclophosphamide. There was reduction of the MRI findings but no improvement in the cognitive deficits. Brain biopsy disclosed noncaseous granulomas and granulomatous angiitis; treatment was changed to high-dose intravenous methylprednisolone, with poor symptomatic response. Conclusion: The diagnosis of RPD due to neurosarcoidosis can be challenging when the disease is restricted to the nervous system. In these cases, clinical presentation of RPD associated with neuroendocrine and visual dysfunction, imaging findings showing hypothalamic lesions and, in some cases, brain biopsy, are the key to a correct diagnosis. It is possible that earlier diagnoses and treatment could have led to a better outcome in these patients.

    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

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

    Full Text Available As technology becomes ubiquitous in society, there is increasing momentum to incorporate it into education. Montessori education is not immune to this push for technology integration. This qualitative study investigates four Upper Elementary Montessori teachers’ attitudes toward technology and technology integration in a public school setting. Interviews and observations were used to understand the teachers’ thoughts and actions regarding technology in the classroom. Both the school context and teacher background played important roles in teachers’ beliefs and actions. Teachers in this study expressed positive views of technology in general, exhibiting high technology efficacy and valuing the development of technology skills in their students. However, all four teachers struggled to include instructional technology in ways that are consistent with a Montessori paradigm. Although individual student use of adaptive tutoring software was the most common use of technology, the teachers varied greatly in both the amount of student time spent on computers and the roles that technology played in their classrooms.

    Solar power technologies will have to become a major pillar in the world's future energy system to combat climate change and resource depletion. However, it is unclear which solar technology is and will prove most viable. Therefore, a comprehensive comparative assessment of solar technologies along the key quantitative and qualitative competitiveness criteria is needed. Based on a literature review and detailed techno-economic modeling for 2010 and 2020 in five locations, we provide such an assessment for the three currently leading large-scale solar technologies. We show that today these technologies cannot yet compete with conventional forms of power generation but approach competitiveness around 2020 in favorable locations. Furthermore, from a global perspective we find that none of the solar technologies emerges as a clear winner and that cost of storing energy differs by technology and can change the order of competitiveness in some instances. Importantly, the competitiveness of the different technologies varies considerably across locations due to differences in, e.g., solar resource and discount rates. Based on this analysis, we discuss policy implications with regard to fostering the diffusion of solar technologies while increasing the efficiency of policy support through an adequate geographical allocation of solar technologies. - Highlights: → We conduct a comprehensive comparative assessment of solar technologies (CSP/PV). → While solar technologies approach competitiveness in 2020, no clear winner emerges. → Solar resource and discount rate heavily impact competitiveness of solar technologies. → Adequate geographical allocation of solar technologies increases policy efficiency. → Focus on key cost down levers and strategic co-benefits of solar technologies needed.

    The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

    The CEA is an organization with a primarily technological focus, and one of the key areas in which it carries out research is Health Technology. This field of research was recognized and approved by the French Atomic Energy Committee on July 20, 2004. The expectations of both the public and health care professionals relate to demands for the highest standards of health care, at minimum risk. This implies a need to diagnose illness and disease as accurately and as at early a stage as possible, to target surgery precisely to deal only with damaged organs or tissues, to minimize the risk of side effects, allergies and hospital-acquired infections, to follow-up and, as far as possible, tailor the health delivery system to each individual's needs and his or her lifestyle. The health care sector is subject to rapid changes and embraces a vast range of scientific fields. It now requires technological developments that will serve to gather increasing quantities of useful information, analyze and integrate it to obtain a full understanding of highly complex processes and to be able to treat the human body as un-invasively as possible. All the technologies developed require assessment, especially in the hospital environment. (authors)

    Yang Quanzhan

    2014-06-01

    Full Text Available Biomedical metal materials with good corrosion resistance and mechanical properties are widely used in orthopedic surgery and dental implant materials, but they can easily cause stress shielding due to the significant difference in elastic modulus between the implant and human bones. The elastic modulus of porous metals is lower than that of dense metals. Therefore, it is possible to adjust the pore parameters to make the elastic modulus of porous metals match or be comparable with that of the bone tissue. At the same time, the open porous metals with pores connected to each other could provide the structural condition for bone ingrowth, which is helpful in strengthening the biological combination of bone tissue with the implants. Therefore, the preparation technologies of porous metal implants and related research have been drawing more and more attention due to the excellent features of porous metals. Selective laser melting (SLM and electron beam melting technology (EBM are important research fields of additive manufacturing. They have the advantages of directly forming arbitrarily complex shaped metal parts which are suitable for the preparation of porous metal implants with complex shape and fine structure. As new manufacturing technologies, the applications of SLM and EBM for porous metal implants have just begun. This paper aims to understand the technology status of SLM and EBM, the research progress of porous metal implants preparation by using SLM and EBM, and the biological compatibility of the materials, individual design and manufacturing requirements. The existing problems and future research directions for porous metal implants prepared by SLM and EBM methods are discussed in the last paragraph.

    Full Text Available Technology analysis (TA is an important issue in the management of technology. Most R&D (Research & Development policies have depended on diverse TA results. Traditional TA results have been obtained through qualitative approaches such as the Delphi expert survey, scenario analysis, or technology road mapping. Although they are representative methods for TA, they are not stable because their results are dependent on the experts’ knowledge and subjective experience. To solve this problem, recently many studies on TA have been focused on quantitative approaches, such as patent analysis. A patent document has diverse information of developed technologies, and thus, patent is one form of objective data for TA. In addition, sustainable technology has been a big issue in the TA fields, because most companies have their technological competitiveness through the sustainable technology. Sustainable technology is a technology keeping the technological superiority of a company. So a country as well as a company should consider sustainable technology for technological competition and continuous economic growth. Also it is important to manage sustainable technology in a given technology domain. In this paper, we propose a new patent analysis approach based on statistical analysis for the management of sustainable technology (MOST. Our proposed methodology for the MOST is to extract a technological structure and relationship for knowing the sustainable technology. To do this, we develop a hierarchical diagram of technology for finding the causal relationships among technological keywords of a given domain. The aim of the paper is to select the sustainable technology and to create the hierarchical technology paths to sustainable technology for the MOST. This contributes to planning R&D strategy for the sustainability of a company. To show how the methodology can be applied to real problem, we perform a case study using retrieved patent documents related to

    The problem of biological security raises alarm due to the real growth of biological threats. Biological security includes a wide scope of problems, the solution of which becomes a part of national security as a necessary condition for the constant development of the country. A number of pathogens, such as human immunodeficiency virus, exotic Ebola and Lassa viruses causing hemorrhagic fever,rotaviruses causing acute intestinal diseases, etc. were first discovered in the last century. Terrorist actions committed in the USA in 2001 using the anthrax pathogen made the problem of biological danger even more important. In Russian Federation, biological threats are counteracted through the united state policy being a part of general state security policy. The biological Security legislation of Russian Federation is chiefly based on the 1992 Federal Law on Security. On the basis of cumulated experience, the President of Russia ratified Basics of Russian Federation's State Policy for Chemical and Biological Security for the Period through 2010 and Beyond on 4 December, 2003. The document determines the main directions and stages of the state development in the area of chemical and biological security. The Federal target program Russian Federation's National Program for Chemical and Biological Security is being developed, and its development is to be completed soon in order to perfect the national system for biological security and fulfill Basics of Russian Federation's State Policy for Chemical and Biological Security for the Period through 2010 and Beyond, ratified by the President.

    Photovoltaics is already a billion dollar industry. It is experiencing rapid growth as concerns over fuel supplies and carbon emissions mean that governments and individuals are increasingly prepared to ignore its current high costs. It will become truly mainstream when its costs are comparable to other energy sources. At the moment, it is around four times too expensive for competitive commercial production. Three generations of photovoltaics have been envisaged that will take solar power into the mainstream. Currently, photovoltaic production is 90% first-generation and is based on silicon wafers. These devices are reliable and durable, but half of the cost is the silicon wafer and efficiencies are limited to around 20%. A second generation of solar cells would use cheap semiconductor thin films deposited on low-cost substrates to produce devices of slightly lower efficiency. A number of thin-film device technologies account for around 5-6% of the current market. As second-generation technology reduces the cost of active material, the substrate will eventually be the cost limit and higher efficiency will be needed to maintain the cost-reduction trend. Third-generation devices will use new technologies to produce high-efficiency devices. Advances in nanotechnology, photonics, optical metamaterials, plasmonics and semiconducting polymer sciences offer the prospect of cost-competitive photovoltaics. It is reasonable to expect that cost reductions, a move to second-generation technologies and the implementation of new technologies and third-generation concepts can lead to fully cost-competitive solar energy in 10-15 years.

    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.

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

  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

    2011-01-01

    The thermal treatment of low and intermediate level radioactive wastes by arc technology is an advanced and promising process. Therefore, this technology is becoming an important part of the waste management systems of new and existing nuclear power plants. However, due to the small number of existing facilities worldwide, limited operating experience and the ongoing need for research and development activities in this area, the reliability of the technology and the economical benefits are not well understood. Therefore, the goal of this report is to provide a basic understanding of the arc discharge technology for low and intermediate level radioactive waste destruction and to review the end product characteristics and the advancements in their improvement. In addition the information in this paper can be used as base for developing of technical, operational and economical criteria for technology selection methodology. (authors)

  17. The field of tension between technology and journalism

    International Nuclear Information System (INIS)

    Hess, W.

    1992-01-01

    The relationship between technology and journalism is explained by nine theses, the seven most important of them being: many public media pay little positive attention to technology. A main reason for this is that among responsible editors there are too few journalists with a fully-fledged scientific education, and almost no engineers; nevertheless the portents are good for technical facts being presented in future in a more competent and detailed way than before; accuracy down to the smallest detail is not in journalism - one the contrary, it is important to grasp trends and put them into the right context; if today there is a field of tension between technology and journalism, it is due also to the fact that quite a few arguments put forward by technicians turned out to be clichees; journalists do not invent their news and reports, but refer to expert statements which, however, are inexpensive; enterprise-specific press relations must be guided by the demands of journalists - otherwise they are not worth the effort; if you (technicians) move towards technology, it is not ''love's labours lost'', because also journalism has moved recently towards technology.

  18. 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

    absorption. The yellow colour of radiohaloes in cordierite is predominately caused by a radio-induced band at ∼23000 cm -1 (most probably due to a colour centre). As shown by measurements on oriented, artificially He-implanted samples, this band is strongly polarised parallel [001] and reaches its maximum intensity at a fluence of about 10 14 He 2+ per cm 2 . At 10 15 He 2+ per cm 2 the coloration has already started to decrease in intensity. This observation is the analog of the well known coloration reversal in natural radiohaloes in cordierite. Fluences up to 10 16 8.8 MeV He 2+ ions per cm 2 did not cause detectable amorphization. In contrast, irradiation with only 10 14 30 MeV O 6+ per cm 2 was sufficient to create local amorphization. The previously proposed radiochemical transformation of channel CO 2 into CO could be experimentally confirmed, and the additional formation of molecular oxygen was discovered. All radiogenic molecules show preferred orientation parallel [100]. The detection of CO in radiohaloes is of major petrological importance because until now the presence of carbon monoxide molecules has solely been assigned to reducing conditions during crystal formation. In contrast, the present study shows that CO can also be produced by the action of radioactivity. Cathodoluminescence investigations were done on radiohaloes in quartz from different localities and artificially irradiated samples. Results showed that the observed CL colour in radiohaloes is the combined result of an overlap of emissions already existing in the host quartz, and a radio-induced broad-band emission at ∼650 nm. It was experimentally confirmed that optically active centres in radiohaloes show a decidedly non-linear, nearly logarithmic dependence on the irradiation dose. Doses higher than 10 15 He 2+ per cm 2 lead to local amorphization near the maximum penetration depth of the irradiated particles.

  20. Particle resuspension due to human walking

    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

    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.

    Future energy production will be performed by advanced technologies that are more efficient, more environmentally friendly and less expensive than current technologies. Integrated gasification combined cycle (IGCC) power plants have been proposed as one of these systems. Utilising biofuels in future energy production will also be emphasised since this lowers substantially carbon dioxide emissions into the atmosphere due to the fact that biomass is a renewable form of energy. Combining advanced technology and biomass utilisation is for this reason something that should and will be encouraged. A. Ahlstrom Corporation of Finland and Sydkraft AB of Sweden have as one part of company strategies adopted this approach for the future. The companies have joined their resources in developing a biomass-based IGCC system with the gasification part based on pressurised circulating fluidized-bed technology. With this kind of technology electrical efficiency can be substantially increased compared to conventional power plants. As a first concrete step, a decision has been made to build a demonstration plant. This plant, located in Vaernamo, Sweden, has already been built and is now in commissioning and demonstration stage. The system comprises a fuel drying plant, a pressurised CFB gasifier with gas cooling and cleaning, a gas turbine, a waste heat recovery unit and a steam turbine. The plant is the first in the world where the integration of a pressurised gasifier with a gas turbine will be realised utilising a low calorific gas produced from biomass. The capacity of the Vaernamo plant is 6 MW of electricity and 9 MW of district heating. Technology development is in progress for design of plants of sizes from 20 to 120 MWe. The paper describes the Bioflow IGCC system, the Vaernamo demonstration plant and experiences from the commissioning and demonstration stages. (orig.)

    Animal welfare is receiving increasing attention from the authorities, the public and NGOs. For this reason, the improvement of animal welfare and animal handling systems is of the utmost importance for the meat industry. Technological developments have led to more animal friendly systems that handle animals on the day of slaughter, and these developments will be even more important as consideration for animal welfare and sustainability is no longer just a trend but a licence to operate. Improvement of animal welfare also leads to a higher value of the carcasses due to higher product quality, less cut-off caused by fewer injuries, and reduced working load, which leads to increased business opportunities. Therefore, good animal welfare is good business, and the development and implementation of new technology is the way to obtain improved animal welfare. These subjects will be addressed using examples and cases from the pork and broiler production industry. Copyright © 2016 Elsevier Ltd. All rights reserved.

  14. Technology Roadmap: Energy Storage

    NONE

    2014-03-01

    Energy storage technologies are valuable components in most energy systems and could be an important tool in achieving a low-carbon future. These technologies allow for the decoupling of energy supply and demand, in essence providing a valuable resource to system operators. There are many cases where energy storage deployment is competitive or near-competitive in today's energy system. However, regulatory and market conditions are frequently ill-equipped to compensate storage for the suite of services that it can provide. Furthermore, some technologies are still too expensive relative to other competing technologies (e.g. flexible generation and new transmission lines in electricity systems). One of the key goals of this new roadmap is to understand and communicate the value of energy storage to energy system stakeholders. This will include concepts that address the current status of deployment and predicted evolution in the context of current and future energy system needs by using a ''systems perspective'' rather than looking at storage technologies in isolation.

On this work, a realistic statement of current status of gallium-arsenide technology will provide and for future this will help to realise the enormous possibilities which we believe lie ahead. Gallium-arsenide integrated circuit technology has historically been portrayed as the technology of future. Now although it has not attained the wide complete applicability, it has gradually becoming an accepted and commercially available source of high-speed integrated circuits. High-speed logic circuits fabricated in gallium arsenide have shown promise for applications such as computing and signal processing. The past fifteen-twenty years have seen the emergence of gallium-arsenide technology from laboratuary to the market place. This innovations have been accompanied by dramatic increases in complexity from early single devices to the integrated circuits of considerable complexity for both digital and analogue applications. The aims to lay down sound principles of forthcoming developments in which both the speed and level of the complexity of gallium-arsenide circuits will increase dramatically meeting needs in such as areas as ultra fast computers, personnel communications and new broadcasting technology.

    1992-12-01

    MMIC technology is recently progressing at a rapid rate and is now being applied in communications systems. However, there remain few practical applications. This is mainly due to the high cost of conventional MMICs because of the small market size and specialized needs. This paper introduces three new technical approaches that overcome the problems: uniplanar MMIC, line unified FET (LUFET), and multilayer MMIC. Concepts and several examples of these technologies are described. It is shown that these technologies are effective not only for cost reduction but also for increased performance. In addition, one example of system application is described.

    2002-01-01

    The invention of the scanning tunneling microscope (STM) prompted researchers to contemplate whether such technology could be used as the basis for the storage and retrieval of information. With magnetic data storage technology facing limits in storage density due to the thermal instability of magnetic bits, the super-paramagnetic limit, the heir-apparent for information storage at higher densities appeared to be variants of the STM or similar probe-based storage techniques such as atomic force microscopy (AFM). Among these other techniques that could provide replacement technology for magnetic storage, near-field optical scanning optical microscopy (NSOM or SNOM) has also been investigated. Another alternative probe-based storage technology called atomic resolution storage (ARS) is also currently under development. An overview of these various technologies is herein presented, with an analysis of the advantages and disadvantages inherent in each particularly with respect to reduced device dimensions. The role of micro electro mechanical systems (MEMS) is emphasized

One of the reasons for the imbalance between resource availability and fishing capacity is technological development, which continuously increases the efficiency of the vessels—a mechanism...... referred to as “technological creep.” We review how the introduction of new and more efficient electronic equipment, gear design, engines, deck equipment, and catch-handling procedures influences the capture efficiency (catchability) of commercial fishing vessels. On average, we estimate that catchability...... increases by 3.2% per year due to technological developments, an increase often ignored in fisheries management. The documentation and quantification of technological creep improves the basis for successfully integrating the effects of technological development (and catchability changes) in fisheries...

    Consumer attitudes play an important role in the acceptance of new technologies. The success of food innovations depends on understanding how consumers form and change attitudes toward food technologies. Earlier post hoc explanations suggest that evaluative conditioning can change consumer...... attitudes toward food technologies. The present study tests how evaluative conditioning can affect consumer acceptance of new food technologies. Furthermore, authors investigate whether evaluative conditioning is resistant to extinction after a two-month period and whether the evaluative conditioning effect...... prevails in a product-related context. Within an evaluative conditioning paradigm including between-subjects control groups in addition to standard within-subjects control conditions, participants were presented with three food technologies (conventional, enzyme, and genetic technology) paired...

    The drive toward new semiconductor technologies is intricately related to market demands for cheaper, smaller, faster, and more reliable circuits with lower power consumption. The development of new processing tools and technologies is aimed at optimizing one or more of these requirements. This goal can, however, only be achieved by a concerted effort between scientists, engineers, technicians, and operators in research, development, and manufac­ turing. It is therefore important that experts in specific disciplines, such as device and circuit design, understand the principle, capabil­ ities, and limitations of tools and processing technologies. It is also important that those working on specific unit processes, such as lithography or hot processes, be familiar with other unit processes used to manufacture the product. Several excellent books have been published on the subject of process technologies. These texts, however, cover subjects in too much detail, or do not cover topics important to modem tech­ n...

    The importance of information technologies to management will always be assessed against its ability to assist the organization in the process of creating value, what will inevitably be associated to the quality of the generated information. Managing information quality is not only a way to ensure that information enables knowledge generation and integration, and the use of this in organizational actions; it is a management philosophy.

    Full Text Available Discovering the antecedents of technology use is of major importance in the field of technology adoption. This study investigates the relationship between the personality dimensions of TRI (Technology Readiness Index and the system specific dimensions of TAM (Technology Acceptance Model. Data was collected from 186 employees in various Norwegian organisations. Structural equation modelling was used to test the relationship between dimensions of TRI and TAM. The results show that optimism and innovativeness significantly influences perceived usefulness and perceived ease of use. Further, perceived usefulness has a significant positive influence on actual usage. The results imply that both personality dimensions and system specific dimensions are of major importance when adopting new technology. This should be considered when organisations develop implementation strategies.

    In an aging society, it is increasingly important to understand how assistive devices can be used by older people to maintain quality of life despite chronic disabilities. Assistive technology is a mainstay of physical therapist practice, but the potential for device use to affect psychosocial well-being is not yet understood at the population level. The objective of this study was to develop a parsimonious indicator that can be used in population-based surveys to represent the effect of assistive technologies on quality of life for older people, separate from personal assistance. This study was a cross-sectional survey. /b> The methods used in this study were psychometric scale development and structural equation modeling. The results indicated that a parsimonious, valid, and reliable scale reflecting quality of life related to assistive device use can be created from 3 questions designed to measure improvements in safety, control, and participation due to technology. The findings also suggested that assistive technology may more effectively improve quality of life for people with greater levels of functional limitations. The data were derived from a cross-sectional survey conducted by telephone. The use of personal assistance, on average, was low; thus, the applicability to a population with more profound care needs has yet to be confirmed. Determining the broader impact of assistive technology on quality of life with population-level measures may provide insight into how best to leverage technologies to prevent dependence in aging adults.

    The unusual radiographic pattern of bleb-like mounds on the surface of the colon mucosa, previously described as colonic urticaria, was seen in 3 patients in whom no allergic state was present. This urticaria-like pattern was due to colonic distention in all 3, and represented only submucosal edema on the gross and microscopic specimens. We hypothesize that this pattern is due to early changes of ischemia caused by colon distention.

    The greenhouse effect due to nitrous oxide in the present atmosphere is about 0.8 K. Increase in atmospheric N2O due to perturbation of the nitrogen cycle by man may lead to an increase in surface temperature as large as 0.5 K by 2025, or 1.0 K by 2100. Other climatic effects of N2O are briefly discussed.

    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

    Full Text Available The growing concern over global warming and significant ecological changes requires sustainable development in all fields of science and technology. Concrete not only consumes huge amount of energy and natural sources, but also emits large amount of CO2, mainly due to the production of cement. It is evident that such large amount of concrete production has put significant impact on the energy, resource, environment, and ecology of the society. Hence, how to develop the concrete technology in a sustainable way has become a significant issue. In this paper, some of Korean researches for sustainable development of concrete are presented. These are sustainable strengthening for deteriorated concrete structure, sustainable reinforcement of new concrete structure, sustainable concrete using recycled aggregate and supplementary cementing materials and finally application of each technique to precast concrete.

    Full Text Available The article aims at thinking the relation between ethics, science and technology, emphasising the problem of their re-linking, after the split into judgements of fact and judgements of value, which happened in the beginning of modern times. Once the warlike Aristocracy's ethics and the saint man's moral are examined, one tries to outline the way by taking as a reference the ethics of responsibility, whose prototype is the wise man's moral, which disappeared in the course of modern times, due to the fragmentation of knowing and the advent of the specialist. At the end of the study, the relation between ethics and metaphysics is discussed, aiming at adjusting the anthropological question to the cosmological perspective, as well as at providing the bases of a new humanism, objectifying the humanising of technique and the generation of a new man, literate at science, technology and the humanities.

    The technology in dentistry has been developed significantly lately, increasing the technological level of new materials, methods and equipment have been developed. Undoubtedly the CO2 laser has contributed to this evolution particular to the treatment of the infected dentin. CO2 laser can sterilize and promote increase 6 to 8 times of dentin resistance, through the transformation the hydroxyapatite in calcium-phosphato-hydroxyapatite. We can reassure our patients about the use of pulsed CO2 laser due to better preservation of dental structure and its benefits permitting advanced esthetic treatments. The CEREC system, registers a tri-dimensional image of the preparation through a scan system, and sends it to the computer and the operator will edit the restorations so the equipment will finish porcelain restoration. The authors used a new laser 650 nm for caries detection and the other low lever laser (670 nm and 730 nm) considered an auxiliary method to prevent and treat the hypersensitivity in dentin.

  18. A review of treatment technologies for MTBE

    International Nuclear Information System (INIS)

    Bass, D.

    1995-01-01

    Available treatment technologies for methyl tertiary butyl ether (MTBE) contamination in soil, groundwater, and recovered groundwater are reviewed and assessed. MTBE contamination is becoming an important issue due to the increasing prevalence and regulation of this gasoline additive. In addition, MTBE is more soluble and more mobile in groundwater than most hydrocarbons, so it is usually the first gasoline constituent to reach sensitive receptors. Treatment of MTBE is complicated by its Henry's constant, which is lower than most other gasoline constituents. Furthermore, evidence of biodegradability of MTBE is mixed, and MTBE does not degrade rapidly abiotically. Groundwater pumping is usually employed to contain and collect MTBE-contaminated groundwater, often successfully because of its high aqueous solubility. Air sparging/soil vapor extraction is also successfully employed to treat MTBE, but its effectiveness is reduced by the low Henry's constant of MTBE. Sparging and other aerobic bioremediation approaches are hampered by the poor biodegradability of MTBE. Oxidation technologies, such as ozone injection, hold promise for rapid in situ remediation of MTBE. Treatment of recovered groundwater contaminated with MTBE is also problematic. MTBE adsorbs poorly to granular activated carbon; advanced oxidation processes are effective on MTBE, but entail high capital and operating costs; bioreactors are of questionable effectiveness on MTBE. Air stripping is usually the most cost-effective treatment technology for MTBE so long as the off gas from the air stripper can be discharged without treatment. However, off gas treatment is expensive, so groundwater is sometimes heated to reduce the requirement for stripping air

    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)

  20. Technology assessment for Spaceship Two, space tourism, and private spaceflight

    Science.gov (United States)

    Hancock, Randy

    A seven-step technology assessment was conducted to address questions regarding the significance and likely consequences associated with the introduction of Spaceship Two, space tourism, and private spaceflight. Impacts were assessed across four categories: the Role and Functions of Government, Private Industry Factors, Cultural and Societal Impacts, and the Time Frame in which these impacts were anticipated to occur. The technology assessment findings were compared to the results of expert interviews that addressed the sane four categories. The researcher noted that, while there was overwhelming agreement between the technology assessment's primary impacts and the expert interview responses, there were several differences. The technology assessment and interviewees agreed that the federal government would likely be both a regulator and user of private spaceflight. Both agreed that business partnerships would be key in pursuing private spaceflight. There was also consensus that, as market forces come to bear, ticket prices would drop and a larger market and broader passenger demographic would emerge. The technology assessment and experts agreed that an accident, especially one early in the industry's evolution, could be disastrous. Both agreed that private spaceflight can serve as a inspiration to students and be a positive influence in society, and both agreed that the start of passenger flights should take place in the 2010 - 2012 timeframe. Due to the potentially disastrous consequences of an accident, there was agreement between the technology assessment and experts on the value of flight and ground crew training, driven by insurance carriers and federal mandate. Most differences between the technology assessment's findings and the expert interview responses were due to omission, rather than direct disagreement. However, this was not the case in every instance. The most significant difference between the technology assessment and the experts involved the
