    The National Marine Fisheries Service (NMFS) has been conducting Natural Rearing Enhancement System (NATURES) research since the early 1990s. NATURES studies have looked at a variety of mechanisms to enhance production of wild-like salmonids from hatcheries. The goal of NATURES research is to develop fish culture techniques that enable hatcheries to produce salmon with more wild-like characteristics and increased postrelease survival. The development of such techniques is called for in the Columbia Basin Fish and Wildlife Program. This document is the draft report for the Supplemental Fish Quality Contract DE-AI79-91BP20651 Over the history of the project, the effects of seminatural raceway habitats, automated underwater feeders, exercise current velocities, live food diets, and predator avoidance training have been investigated. The findings of these studies are reported in an earlier contract report (Maynard et al. 1996a). The current report focuses on research that has been conducted between 1999 and 2002. This includes studies on the effect of exercise on salmon and steelhead trout, effects of predator avoid training, integration of NATUES protocols into production hatcheries, and the study of social behavior of steelhead grown in enriched and conventional environments. Traditionally, salmon (Oncorhynchus spp.) are reared in barren concrete raceways that lack natural substrate, in-stream structure, or overhead cover. The fish are fed in an unnatural manner with artificial feeds mechanically or hand broadcast across the water surface. This traditional approach has increased the egg-to-smolt survival of hatchery-reared fish by an order of magnitude over that experienced by wild-reared salmon. However, once hatchery-reared fish are released into the wild their smolt-to-adult survival is usually much lower than wild-reared salmon. The reduced postrelease survival of hatchery-reared fish may stem from differences in their behavior and morphology compared to wild

    This in turn means a change in the orientation of the R&D that ENRESA has been performing to date, the first step in this direction being the current Plan, which will cover the period 1999-2003. On the basis of the above, and closely tracking the progress mode and the situation existing in the other countries of the OECD and EU involved in similar programmes, the new R&D Plan includes a series of areas of research that cover all the internationally considered radioactive waste management options and alternatives. These include R&D activities that range from the exhaustive treatment of irradiated fuels (advanced reprocessing and transmutation) to the direct storage of spent fuel (open cycle). The latter was the only option considered in previous R&D Plans, which proposed the construction of a deep geological disposal facility by around the year 2025. As has been pointed out above, this new R&D approach, which implies a wider view of spent fuel management options, including separation and transmutation, along with modulation in budgeting, in order to adopt to a longer timeframe for implementation of the possible solutions, is embodied in the new GRWP. The objective and activities considered in this Plan are to make a decisive contribution of the scientific and technological bases supporting future decision-making on the most adequate way of addressing the definitive management of high level wastes.

    The annual effective doses evaluated by the Individual Monitoring Service of the Radiological Protection and Nuclear Safety Department (D.P.R.S.N.) of the Nuclear and Technological Institute (I.T.N.) in Portugal, in the 5-year period from 1999 - 2003, are analysed and presented in this paper. In this period, the I.M.S. at I.T.N.-D.P.R.S.N. monitored nearly 91% of all the monitored population in Portugal. In 2003, approximately 9,000 professionally exposed workers from 970 facilities spread from all over the country were monitored. The workers are organized in four fields of activity, namely conventional industry, research, medicine and mining. In the period from 1999 to 2003, the workers from the medical sector represented 80-85% of the monitored population. In Portugal there are no nuclear power plants but there is a nuclear research reactor at I.T.N. premises. People working at the reactor were included in the research field. In this period, the number of workers involved in the mining field decreased as the exploration of natural Uranium ore was gradually discontinued. During this period there were two monitoring systems operating at the I.M.S. of I.T.N.-D.P.R.S.N., one based on film and the other one based on thermoluminescence detectors (TLD). An effort was made to transfer people monitored by film to TLD and in 2003 nearly 6,500 workers (approx.) were monitored with this methodology. Workers shifted from film to TLD monitoring method were taken into account and considered only once. In this work, the annual whole body doses evaluated in the period 1999 to 2003 were considered. The distribution of workers in each field of activity was determined and the distribution of workers by dose intervals in each field is presented. The annual average doses were computed for the total monitored population and for the exposed workers in each field of activity. The annual collective doses in each field of activity and the total collective doses were also determined and

    Full Text Available OBJECTIVE: To describe the characteristics of randomized controlled clinical trials (RCT on cancer drugs conducted in Spain between 1999 and 2003 based on their protocols. METHODS: We conducted an observational retrospective cohort study to identify the protocols of RCTs on cancer drugs authorized by the Agencia Española del Medicamento y Productos Sanitarios (AEMPS (Spanish Agency for Medicines and Medical Devices during 1999-2003. A descriptive analysis was completed and the association between variables based on the study setting and sponsorship were assessed. RESULTS: We identified a total of 303 protocols, which included 176,835 potentially eligible patients. Three-quarter of the studies were internationally-based, 61.7% were phase III, and 76.2% were sponsored by pharmaceutical companies. The most frequently assessed outcomes were response rate (24.7%, overall survival (20.7%, and progression-free survival (14.5%. Of all protocols, 10.6% intended to include more than 1000 patients (mean: 2442, SD: 2724. Compared with their national counterparts, internationally-based studies were significantly larger (p<0.001 and were more likely to implement centralized randomization (p<0.001, blinding of the intervention (p<0.001, and survival as primary outcome (p<0.001. Additionally, most internationally-based studies were sponsored by pharmaceutical companies (p<0.01. In a high percentage of protocols, the available information was not explicit enough to assess the validity of each trial. Compared to other European countries, the proportion of Spanish cancer drugs protocols registered at www.clinicaltrials.gov (7% was lower. CONCLUSION: RCTs on cancer drugs conducted in Spain between 1999 and 2003 were more likely to be promoted by pharmaceutical companies rather than by non-profit national groups. The former were more often part of international studies, which generally had better methodological quality than national ones. There are some worldwide

    Full Text Available This study aims to develop statistical models for forecasting the quantity of the various types of marine fish landed at Pattani Fishery Port, allowing for trend and seasonality, using official data during 1999-2003. The data comprise daily and monthly totals by weight for eight types of fish (mackerel, other food fish, squid, scads, trash fish, shrimp, lobster and crab. The statistical methods are one-way analysis of variance, multiple linear regression and time series forecasting using trend and seasonal models. It is found that mackerel, other food fish and squid catches tend to decrease, whereas the catches of scads tend to increase, and trash fish catches have no detectable trend up or down. Shrimp and lobster tend to decrease exponentially, and the trend of crab catch is constant. This study raises questions about the ecological and economic sustainability of the current fisheries policy in Thailand.

  11. Geodetic deformation Across the Central Apennines from GPS Data in the time span 1999-2003

    Full Text Available Abstract During the time span 1999-2003 was set up and repeatedly surveyed a not permanent GPS network located across one of the highest seismic areas of the central Apennines (Italy. The Central Apennine Geodetic Network (CA-GeoNet, extends across Umbria, Abruzzo, Marche and Lazio regions, in an area of ?180x130 km, from Tyrrhenian to the Adriatic sea. It consists in 125 GPS stations distributed at 3-5 km average grid and includes 7 permanent GPS stations operated by the Italian Space Agency (ASI and the Istituto Nazionale di Geofisica and Vulcanologia (INGV. With the aim to estimate the active strain rate across this part of the chain, the GPS sites have been located on the main geological units of the area and across the typical basin and range structures, related with the main seismogenic faults. In this paper we show the network and the first results obtained for a subset of 23 stations that have been occupied at least during three repeated campaigns, in the time span 1999-2003. Data analysis, performed by Bernese 4.2 software, shows an extensional rate normal to the chain, in agreement with geological and seismic data. The strain rates in the inner chain are ranging from 12x10-9±11yr-1 to 16x10-9±11yr-1 and from -14x10-9±11yr-1 to -3x10-9±11yr-1. This result provides an improved estimation of the ongoing deformation of this area with respect to previous studies and is in agreement with the style of deformation inferred from seismicity and with the features of the main seismogenic sources from recent geological and seismological investigations.

  12. Annual Cycles of Multiyear Sea Ice Coverage of the Arctic Ocean: 1999-2003

    2004-01-01

    For the years 1999-2003, we estimate the time-varying perennial ice zone (PIZ) coverage and construct the annual cycles of multiyear (MY, including second year) ice coverage of the Arctic Ocean using QuikSCAT backscatter, MY fractions from RADARSAT, and the record of ice export from satellite passive microwave observations. An area balance approach extends the winter MY coverage from QuikSCAT to the remainder of the year. From these estimates, the coverage of MY ice at the beginning of each year is 3774 x 10(exp 3) sq km (2000), 3896 x 10(exp 3) sq km (2001), 4475 x 10(exp 3) sq km (2002), and 4122 x 10(exp 3) sq km (2003). Uncertainties in coverage are approx.150 x 10(exp 3) sq km. In the mean, on 1 January, MY ice covers approx.60% of the Arctic Ocean. Ice export reduces this coverage to approx.55% by 1 May. From the multiple annual cycles, the area of first-year (FY) ice that survives the intervening summers are 1192 x 10(exp 3) sq km (2000), 1509 x 10(exp 3) sq km (2001), and 582 x 10(exp 3) sq km (2002). In order for the MY coverage to remain constant from year to year, these replenishment areas must balance the overall area export and melt during the summer. The effect of the record minimum in Arctic sea ice area during the summer of 2002 is seen in the lowest area of surviving FY ice of the three summers. In addition to the spatial coverage, the location of the PIZ is important. One consequence of the unusual location of the PIZ at the end of the summer of 2002 is the preconditioning for enhanced export of MY ice into the Barents and Kara seas. Differences between the minimums in summer sea ice coverage from our estimates and passive microwave observations are discussed.

    The national Wood Energy Technology Programme was carried out by Tekes during the period 1999- 2003 to develop efficient technology for large- scale production of forest chips from small- sized trees and logging residues. This is the final report of the programme, and it outlines the general development of forest chip procurement and use during the programme period. In 2002, a sub-programme was established to address small-scale production and use of wood fuels. This sub-programme will continue to the end of 2004, and it is not reported here. The programme was coordinated by VTT Processes. As of January 2004, the programme consisted of 44 public research projects, 46 industrial or product development projects, and 29 demonstration projects. Altogether, 27 research organizations and 53 enterprises participated. The total cost of the programme was 42 M euro of which 13 M euro was provided by Tekes. The Ministry of Trade and Industry provided investment aid for the new technology employed in the demonstration projects. When the programme was launched at the end of the 1990s, the major barriers to the use of forest chips were high cost of production, shortage of reliable chip procurement organizations, and the unsatisfactory quality of fuel. Accordingly, the programme focused largely on these problems. In addition, upgrading of the fuel properties of bark was also studied. The production of forest chips must be adapted to the existing operating environment and infrastructure. In Finland, these are charaterized by rich bio-mass potential, a sophisticated and efficient organization for the procurement of industrial timber, a large capacity of heating and CHP plants to use wood fuels, the possibility to co-fire wood and peat, and the unreserved acceptance of society at large. A goal of Finnish energy and climate strategies is to use 5 million m3 (0.9 Mtoe) chips annually by 2010. The Wood Energy Technology Programme was an important link in the long chain of activities

    in soil slightly exceed the U.S. Environmental Protection Agency toxicity-derived ecological soil-screening levels for avian wildlife. Plutonium concentration in the soil was near zero. Wheat-grain data were insufficient to determine any measurable effects from biosolids. Comparison with similar data from other parts of North America where biosolids were not applied indicates similar concentrations. However, the Deer Trail study area had higher nickel concentrations in wheat from both the biosolids-applied fields and the control fields. Plutonium content of the wheat was near zero. Ground-water levels generally declined at most wells during 1999 through 2003. Ground-water quality did not correlate with ground-water levels. Vertical ground-water gradients during 1999 through 2003 indicate that bedrock ground-water resources downgradient from the biosolids-applied areas are not likely to be contaminated by biosolids applications unless the gradients change as a result of pumping. Ground-water quality throughout the study area varied over time at each site and from site to site at the same time, but plutonium concentrations in the ground water always were near zero. Inorganic concentrations at well D6 were relatively high compared to other ground-water sites studied. Ground-water pH and concentrations of fluoride, nitrite, aluminum, arsenic, barium, chromium, cobalt, copper, lead, mercury, nickel, silver, zinc, and plutonium in the ground water of the study area met Colorado standards. Concentrations of chloride, sulfate, nitrate, boron, iron, manganese, and selenium exceeded Colorado ground-water standards at one or more wells. Nitrate concentrations at well D6 significantly (alpha = 0.05) exceeded the Colorado regulatory standard. Concentrations of arsenic, cadmium, chromium, lead, mercury, nickel, and zinc in ground water had no significant (alpha = 0.05) upward trends.

    Finland is enhancing its use of renewable sources in energy production. From the 1995 level, the use of renewable energy is to be increased by 50 % by 2010, and 100 % by 2025. Wood-based fuels will play a leading role in this development. The main source of wood-based fuels is processing residues from the forest industries. However, as all processing residues are already in use, an increase is possible only as far as the capacity and wood consumption of the forest industries grow. Energy policy affects the production and availability of processing residues only indirectly. Another large source of wood-based energy is forest fuels, consisting of traditional firewood and chips comminuted from low-quality biomass. It is estimated that the reserve of technically harvest-able forest biomass is 10-16 Mm' annually, when no specific cost limit is applied. This corresponds to 2-3 Mtoe or 6-9 % of the present consumption of primary energy in Finland. How much of this re-serve it will actually be possible to harvest and utilize depends on the cost competitiveness of forest chips against alternative sources of energy. A goal of Finnish energy and climate strategies is to use 5 Mm' forest chips annually by 2010. The use of wood fuels is being promoted by means of taxation, investment aid and support for chip production from young forests. Furthermore, research and development is being supported in order to create techno-economic conditions for the competitive production of forest chips. In 1999, the National Technology Agency Tekes established the five-year Wood Energy Technology Programme to stimulate the development of efficient systems for the large-scale production of forest chips. Key tar-gets are competitive costs, reliable supply and good quality chips. The two guiding principles of the programme are: (1) close cooperation between researchers and practitioners and (2) to apply research and development to the practical applications and commercialization.

    Use of unsealed radiopharmaceuticals in Iran's nuclear medicine centers has expanded rapidly in the last decade. As part of a nationwide survey, this study was undertaken to estimate the radiation risk due to the diagnostic nuclear medicine procedures performed in Tehran in 1999-2003. During the five years of the study, the data of 101,540 yearly examinations of diagnostic nuclear medicine were obtained for 34 (out of 40) active nuclear medicine centers in Tehran. The patients studied were aged 1 y, 5 y, 10 y, 15 y, and adults (>15 y). Compared to an earlier investigation in 1989 (which was published in 1995), striking changes were found to be occurring in the trends of nuclear medicine in Tehran in a matter of a decade. The frequency of cardiac examinations increased from less than 1% in 1989 to 43.2% (mean of 5 y) in 2003; thyroid examinations, with the relative frequency of higher than 80% in 1989, decreased to 26.7% in the current investigation (averaged for 2001); and the number of overall examinations per 1,000 population of Tehran increased from 1.9 in 1989 to 8.8 in this study (about fourfold). The decrease in relative frequency of thyroid examinations could be attributed to the lower referral policy (mainly by specialists), decreased incidence of goiter due to implementation of programs for iodine enrichment diets, introduction of fine needle aspiration (FNA), and sonography techniques for diagnosis of thyroid disease. The large increase in relative frequency of cardiac examinations could be due to the increase in the number of single photon emission computerized tomography (SPECT) systems in recent years as compared to 1989 in Tehran. The collective effective dose increased from 400 (person-Sv) in 1999 to 529 (person-Sv) in 2003, and the effective dose per capita increased from 34.80 μSv in 1999 to 44.06 μSv in 2003 (average, 35.60 μSv).

    The thick vadose zone that underlies the Idaho National Engineering and Environmental Laboratory has been recognized both as an avenue through which contaminants disposed at or near the ground surface can migrate to groundwater in the underlying Eastern Snake River Plain aquifer, and as a barrier to the movement of contaminants into the aquifer. Flow and contaminant transport in the vadose zone at the INEEL is complicated by the highly heterogeneous nature of the geologic framework and by the variations in the behavior of different contaminants in the subsurface. The state of knowledge concerning flow and contaminant transport in the vadose zone at and near the INEEL IN 1999 was summarized in Deficiencies in Vadose Zone Understanding at the Idaho National Engineering and Environmental Laboratory (Wood et al., 2000). These authors identified deficiencies in knowledge of flow and contaminant transport processes in the vadose zone, and provided recommendations for additional work that should be conducted to address these deficiencies. In the period since (Wood et al., 2000) was prepared, research has been published that, to some degree, address these deficiencies. This document provides a bibliography of reports, journal articles, and conference proceedings published 1999 through mid-2003 that are relevant to the vadose zone at or near the INEEL and provides a brief description of each work. Publications that address specific deficiencies or recommendations are identified, and pertinent information from selected publications is presented.

    Cancer and chronic disease are leading causes of death in the US with an estimated cost of $46 billion. We analyzed 11 million cause-specific deaths of US workers age 18-64 years in 30 states during 1985-1999, 2003-2004, and 2007 by occupation, industry, race, gender, and Hispanic origin. The highest significantly elevated proportionate leukemia mortality was observed in engineers, protective service, and advertising sales manager occupations and in banks/savings &loans/credit agencies, public safety, and public administration industries. The highest significantly elevated smoking-adjusted acute myocardial infarction mortality was noted in industrial and refractory machinery mechanics, farmers, mining machine operators, and agricultural worker occupations; and wholesale farm supplies, agricultural chemical, synthetic rubber, and agricultural crop industries. Significantly elevated risks for acute myocardial infarction and leukemia were observed across several occupations and industries that confirm existing reports and add new information.

    core samples indicate an average primary-wave velocity of about 5,515 feet per second, a bimodal distribution of density between 2.19 and 2.32 grams per cubic centimeter with an average of 2.16 grams per cubic centimeter, and a magnetic susceptibility that generally ranged between 9 and 40 with an average of 22. Water-chemistry data indicate that the ground water in the alluvial aquifers generally is low in total dissolved solids and chloride and of good quality. Isotopic data indicate that water from artificial recharge is present throughout the shallower parts of the aquifer system but may not be present toward the center of the valley. The percentage of water from artificial recharge present in ground water ranges from 0 to 61 percent for water-supply wells. The age of most shallow ground water is less than 2,000 years before present, and the age of deeper ground water is as much as 39,900 years before present, as determined from carbon age dates. Initial water-level data from the multiple-well monitoring sites indicate seasonal water-level fluctuations as great as 60 feet and water-level differences between aquifers as great as 10 feet. The water-level hydrographs indicate different water-level changes and relations between aquifers in different parts of the basin. However, most of these hydrographs indicate the potential for downward water-level gradients, with lower hydraulic heads in the deeper monitoring wells. Hydraulic properties of selected new monitoring wells indicate that horizontal hydraulic conductivities range from 0.1 to 583 feet per day. Hydraulic testing of selected core samples yielded vertical hydraulic conductivity values ranging from 8 x 10-4 to 0.3 feet per day, and effective porosity values ranging from 0.21 to 0.4. Geomechanical properties estimated from one-dimensional consolidation tests of selected core samples resulted in geometric mean inelastic and elastic specific storage values of 1.5 x 10-

    This biennial progress report highlighted actions undertaken by Canada and the United States in the last 2 years to address transboundary air pollution within the context of the Air Quality Agreement regarding acid rain and ground-level ozone. The report was divided into 3 sections. The first section provided information concerning commitments to emission reductions in acid rain and ozone annexes. Section 2 provided details of related air quality efforts. Section 3 presented information on scientific and technical cooperation and research, which included details of health effects and acid deposition effects, recovery efforts and critical loads and exceedances. The progress report also included the third 5-year comprehensive review of the Air Quality Agreement, which was organized in a question and answer format to address requirements in the agreement and public comments on the 2004 progress report. In October 2006, Canada's federal government tabled the Clean Air Act as a new legislation that would expand the government's authorities to take action to reduce air emissions of greenhouse gases and other air pollutants. The Notice of Intent to develop and implement regulations and other measures to reduce air emissions was also revealed. The regulations would address anthropogenic sources of air pollution, including fossil-fuel electricity production, petroleum industry, smelters, forest products, chemicals production and transportation. The report showed that over the last 2 years, both countries have reduced their emissions of sulfur dioxide (SO{sub 2}) and nitrogen oxides (NO{sub x}), and have made progress in meeting the requirements of the Ozone Annex to reduce emissions of NO{sub x} and volatile organic compounds (VOCs). Actions have focused on reducing emissions from major sources such as electric generating units, industrial sources, and on-road and nonroad transportation. It was concluded that to date, the agreement has provided opportunities for

    Metabolic acidosis (MA) is relatively common in patients with chronic kidney disease (CKD) particularly in stages 4 and 5. It is assumed to play a contributory role in the development of several complications including bone disease, skeletal muscle wasting, altered protein synthesis, and degradation. Recent evidence also suggests that even mild acidosis might play a role in progressive glomerular filtration rate loss. Experimental and clinical studies suggest that correction of acidosis by alkali therapy attenuates these complications and improves quality of life. Despite several recent small and single-center studies supporting this notion, more robust evidence is required with regard to the long-term benefits of alkali therapy, type of alkali supplements, and the optimal level of serum bicarbonate.

    Full Text Available Within the framework of growing concern for analyzing the quality of young democracies, this article focuses on the Paraguayan case. A democracy sometimes neglected by the academic literature. However, Paraguay is drawing attention as a consequence of Colorado’s Party defeat (in office since 1947 in the 2008 presidential election. A theoretical and methodological thinking about the concept of the quality of democracy together with an empirical research have been done in this article. Five essential dimensions have been taken into consideration: political rights and civil liberties; rule of law; accountability; responsiveness and political participation. The main conclusion is that Paraguay has a low quality democracy, far away from the rest of Latin American countries. This statement is backed up by three different explanations that are, at the same time, interlinked. These are the following: socioeconomic factors, features of its own political institutions (above all, the widespread clientelism and, finally, political parties’ interests and strategies.

    Full Text Available The vagueness of the concept of ‘sustainable development’ ceased to serve as a consensus platform and instead became a source of controversy. Therefore an instrument is needed to measure whether we are striving towards sustainable development or not. Today the most widely used indicator of economic prosperity is gross domestic product (GDP. It is often incorrectly interpreted as an indicator of quality of life. If, however, GDP is considered to be quality-of-life indicator, it is a misleading indicator as GDP does not cover the services people conduct outside the official market. As a result, environmentalists together with economists have long been cooperating in designing an alternative indicator capable of better capturing the development of society. Even though GDP is good for measuring economic performance, it is highly misleading as an indicator of the quality and sustainability of life. This article describes briefly the most relevant alternative indicators to GDP developed during last two decades including Czech and Slovak methodology of the Quality and Sustainability of Life Index.

    Since the elderly population is increasing rapidly in developing countries which may decrease the physical activity and exercise and in turn could affect the elderly's quality of life, this study aimed to investigate the effect of progressive muscle relaxation on the elderly's quality of life in Iran. In a randomized clinical trial, participants were randomly divided into intervention and control groups. For the intervention group, muscular progressive relaxation was run three days per week for three months (totally 36 sessions). In relaxation, a patient contract a group of his/her muscles in each step and relaxes them after five seconds and finally loosens all muscles and takes five deep breaths. Each session lasts for 45 minutes. The instrument of data gathering consisted of questionnaires on individual's demographic data and quality of life SF-36. After intervention, quality of life increased significantly in the patients undergoing muscular progressive relaxation and fatigue severity decreased significantly in the intervention group compared to prior to intervention. In addition, there was a statistically significant difference in mean score of physical performance, restricted activity after physical problem, energy, socially function, physical pain, overall hygiene, and quality of life between intervention and control groups. By implementing regular and continuous progressive muscle relaxation, quality of life could be increased in different dimensions in the elderly and the context could be provided to age healthily and enjoy higher health and autonomy. Therefore, all of the therapeutic staffs are recommended to implement this plan to promote the elderly's quality of life.

    The objective of this report was to assess to what extent the NEC Directive's environmental and health objectives concerning acidification, eutrophication and ground-level ozone exposure for the year 2010 have been achieved. The main basis for the assessment is the emission inventory data officially reported by Member States. The analysis was conducted by using the same scientific methods of 2001 (original knowledge) and 2010 (present knowledge) that support European air pollution abatement policies. The original knowledge consisted of modelling concentrations and exposure using the older Lagrangian EMEP model (utilising a 150 x 150 km{sup 2} grid for the computation of grid-average S and N depositions and ground-level ozone concentrations, together with the 1998 European critical load database for assessing the risk of acidification and eutrophication). The assessment performed on the basis of present knowledge used the current Eulerian EMEP model on a 50 x 50 km{sup 2} grid for the computation of ecosystem-specific depositions and ground-level ozone concentrations, in combination with the 2008 European critical loads database. When assessing progress using original knowledge, the NEC Directive's interim environmental acidification objective has been met in almost all grid cells, while the eutrophication objective - provided in a footnote within the NEC Directive and which was formulated on the European Union area as a whole - has been met both for the EU-15 and the EU-27 regions as a whole. If, in contrast, the eutrophication objective had been required to be met in individual grid cells (as for acidification) or in individual Member States, it would be exceeded in many grid cells and in 11 Member States. While acidification has been markedly reduced, eutrophication is now recognised as a major environmental problem in Europe, especially in the context of its potential adverse impacts on biodiversity. An assessment using present knowledge indicates that

    Quality and Safety Education for Nurses (QSEN) faculty outlined 6 competency domains: patient-centered care, teamwork and collaboration, evidence-based practice, quality improvement, safety, and informatics. In this study, 18 subject matter experts participated in a web-based modified Delphi survey between October 2008 and February 2009 to determine whether there was consensus on the developmental progression of knowledge, skill, and attitude elements within the QSEN competencies. Support for creation of curricular threads to facilitate student progressive achievement of the QSEN competencies was validated. Competency development related to the individual patient was emphasized early in the curriculum, whereas teams and systems were emphasized later. Complex concepts such as teamwork and collaboration, evidence-based practice, quality improvement, and informatics were emphasized in advanced courses. Experts outlined a developmental approach in curriculum design, which would potentially encourage practice, reinforcement of learning, and recognition of context of care.

    Rice is a staple food for more than 3 billion people in more than 100 countries of the world but ironically it is deficient in many bioavailable vitamins, minerals, essential amino- and fatty-acids and phytochemicals that prevent chronic diseases like type 2 diabetes, heart disease, cancers and obesity. To enhance the nutritional and other quality aspects of rice, a better understanding of the regulation of the processes involved in the synthesis, uptake, transport and metabolism of macro-(starch, seed storage protein and lipid) and micronutrients (vitamins, minerals and phytochemicals) is required. With the publication of high quality genomic sequence of rice, significant progress has been made in identification, isolation and characterization of novel genes and their regulation for the nutritional and quality enhancement of rice. During the last decade, numerous efforts have been made to refine the nutritional and other quality traits either by using the traditional breeding with high through put technologies such as marker assisted selection and breeding, or by adopting the transgenic approach. A significant improvement in vitamins (A, folate and E), mineral (iron), essential amino acid (lysine) and flavonoids levels has been achieved in the edible part of rice, i. e. endosperm (biofortification) to meet the daily dietary allowance. However, studies on bioavailability and allergenicity on biofortified rice are still required. Despite the numerous efforts, the commercialization of biofortified rice has not yet been achieved. The present review summarizes the progress and challenges of genetic engineering and /or metabolic engineering technologies to improve rice grain quality, and presents the future prospects in developing nutrient dense rice to save the ever-increasing population, that depends solely on rice as the staple food, from widespread nutritional deficiencies.

    Progress is reported in studies to determine the effect of acute, toxic exposures of ozone to alfalfa, potato, and soybean plants. The objective has been to correlate the foliar response with alterations in quality of the edible portion of the plant viz. the leaf, tuber and seed of alfalfa, potato and soybean, respectively. In 1977 we (1) modified our fumigation facilities, (2) developed protocol for studies with alfalfa and potato, and (3) conducted studies on flavonoid status of alfalfa and a series of parameters of potato tubers. In 1978 we (1) conducted more indepth studies with alfalfa, (2) repeated the potato study, (3) began to develop protocol for measuring additional parameters of alfalfa and potato quality, and (4) developed protocol for cultivating and exposing soybean plants.

    Co-pyrolysis of biomass with abundantly available materials could be an economical method for production of bio-fuels. However, elimination of oxygenated compounds poses a considerable challenge. Catalytic co-pyrolysis is another potential technique for upgrading bio-oils for application as liquid fuels in standard engines. This technique promotes the production of high-quality bio-oil through acid catalyzed reduction of oxygenated compounds and mutagenic polyaromatic hydrocarbons. This work aims to review and summarize research progress on co-pyrolysis and catalytic co-pyrolysis, as well as their benefits on enhancement of bio-oils derived from biomass. This review focuses on the potential of plastic wastes and coal materials as co-feed in co-pyrolysis to produce valuable liquid fuel. This paper also proposes future directions for using this technique to obtain high yields of bio-oils.

    The classic tool of assessing learning progress are written tests and assignments. In large groups of students the workload often does not allow in depth evaluation during the course. Thus our aim was to modify the course to include active learning methods and student centered teaching. We changed the course structure only slightly and established new assessment methods like minute papers, short tests, mini-projects and a group project at the end of the semester. The focus was to monitor the learning progress during the course so that problematic issues could be addressed immediately. The year before the changes 26.76 % of the class failed the course with a grade average of 3.66 (Pass grade is 4.0/30 % of achievable marks). After introducing student centered teaching, only 14 % of students failed the course and the average grade was 3.01. Grades were also distributed more evenly with more students achieving better results. We have shown that even in large groups of students with > 100 participants student centered and active learning is possible. Although it requires a great work overhead on the behalf of the teaching staff, the quality of teaching and the motivation of the students is increased leading to a better learning environment.

    Grain yield of hybrid varieties and population varieties in official German variety trials increased by 23.3 and 18.1%, respectively, over the last 26 years. On-farm gain in grain yield (18.9%) was comparable to that of population varieties in variety trials, yet at a level considerably lower than in variety trials. Rye quality is subject to large year-to-year fluctuation. Increase in grain yield and decline of protein concentration did not negatively influence quality traits. Performance progress of grain and quality traits of 78 winter rye varieties tested in official German trials to assess the value for cultivation and use (VCU) were evaluated during 1989 and 2014. We dissected progress into a genetic and a non-genetic component for hybrid and population varieties by applying mixed models, including regression components to model trends. VCU trial results were compared with grain yield and quality data from a national harvest survey (on-farm data). Yield gain for hybrid varieties was 23.3% (18.9 dt ha(-1)) and for population varieties 18.1% (13.0 dt ha(-1)) relative to 1989. On-farm yield progress of 18.9% (8.7 dt ha(-1)) was considerably lagging behind VCU trials, and mean yield levels were substantially lower than in field trials. Most of the yield progress was generated by genetic improvement. For hybrid varieties, ear density was the determining yield component, whereas for population varieties, it was thousand grain mass. Results for VCU trials showed no statistically significant gains or losses in rye quality traits. For on-farm data, we found a positive but non-significant gain in falling number and amylogram viscosity and temperature. Variation of grain and quality traits was strongly influenced by environments, whereas genotypic variation was less than 19% of total variation. Grain yield was strongly negatively associated with protein concentration, yet was weakly to moderately positively associated with quality traits. In general, our results from VCU

    There is an increasing number of new oncology drugs being studied, approved and put into clinical practice based on improvement in progression-free survival, when no overall survival benefits exist. In oncology, the association between progression-free survival and health-related quality of life is currently unknown, despite its importance for patients with cancer, and the unverified assumption that longer progression-free survival indicates improved health-related quality of life. Thus far, only 1 study has investigated this association, providing insufficient evidence and inconclusive results. The objective of this study protocol is to provide increased transparency in supporting a systematic summary of the evidence bearing on this association in oncology. Using the OVID platform in MEDLINE, Embase and Cochrane databases, we will conduct a systematic review of randomised controlled human trials addressing oncology issues published starting in 2000. A team of reviewers will, in pairs, independently screen and abstract data using standardised, pilot-tested forms. We will employ numerical integration to calculate mean incremental area under the curve between treatment groups in studies for health-related quality of life, along with total related error estimates, and a 95% CI around incremental area. To describe the progression-free survival to health-related quality of life association, we will construct a scatterplot for incremental health-related quality of life versus incremental progression-free survival. To estimate the association, we will use a weighted simple regression approach, comparing mean incremental health-related quality of life with either median incremental progression-free survival time or the progression-free survival HR, in the absence of overall survival benefit. Identifying direction and magnitude of association between progression-free survival and health-related quality of life is critically important in interpreting results of oncology

    Monitoring of progress towards the Millennium Development Goal (MDG) drinking water target relies on classification of water sources as “improved” or “unimproved” as an indicator for water safety. We adjust the current Joint Monitoring Programme (JMP) estimate by accounting for microbial water quality and sanitary risk using the only-nationally representative water quality data currently available, that from the WHO and UNICEF “Rapid Assessment of Drinking Water Quality”. A principal components analysis (PCA) of national environmental and development indicators was used to create models that predicted, for most countries, the proportions of piped and of other-improved water supplies that are faecally contaminated; and of these sources, the proportions that lack basic sanitary protection against contamination. We estimate that 1.8 billion people (28% of the global population) used unsafe water in 2010. The 2010 JMP estimate is that 783 million people (11%) use unimproved sources. Our estimates revise the 1990 baseline from 23% to 37%, and the target from 12% to 18%, resulting in a shortfall of 10% of the global population towards the MDG target in 2010. In contrast, using the indicator “use of an improved source” suggests that the MDG target for drinking-water has already been achieved. We estimate that an additional 1.2 billion (18%) use water from sources or systems with significant sanitary risks. While our estimate is imprecise, the magnitude of the estimate and the health and development implications suggest that greater attention is needed to better understand and manage drinking water safety.

    2010-01-01

    A complete scheme for solving the key scientific problems associated with high-standard,high-intensity continuous construction of high arch dams was presented. First,based on a coupling analysis of construction system decomposition and coordination for a high arc dam,a mathematical model for real-time control of construction quality and progress that considers complex constraints was developed. Second,a method of progress control was proposed based on a dynamic simulation. Third,a dynamic quality control mechanism was established based on construction information collected using a PDA. Fourth,a system for integrating collected information,progress simulation and quality control analyses under a network environment was developed. Finally,these methods were applied to a practical project to show that each aspect of a construction process can be managed effectively and that real-time monitoring and feedback control can be realized. Our methods provide new theoretical principles and technical measures for quality and progress control in the high arc dam construction process.

    Full Text Available This article deals with the significance of autonomy and relatedness as central needs in intimate relationships. It examines the influences of need satisfaction on relationship quality and progressive union formation (“institutionalisation” processes of intimate relationships. Using a random sample of 1,914 couples in a longitudinal, dyadic survey design, we ascertained the actor and partner effects of autonomy and relatedness on relationship quality and the union formation process. A cluster analysis resulted in four types of relationship need satisfaction, distinguished by high values in both domains, high values in only one of the domains, or low need satisfaction in both domains. Balanced fulfilment of autonomy and relatedness predicts the comparatively highest values of relationship satisfaction and future orientation (commitment. Moreover, low need satisfaction in relationships reduces the progress of union formation processes (cohabitation, marriage, childbirth. Women demonstrate more intense actor and partner effects of relationship need satisfaction than men.

    Background and aims This review appraises the progression and status of the evidence base for the treatment of compulsive buying disorder (CBD), in order to highlight what currently works and to prompt useful future research. Methods Online databases ISI Web of Knowledge, PsycINFO, and PubMed via Ovid were searched at two time points. Two quality checklists and an established model of therapy evaluation (hourglass model) evaluated the quality and progression of both psychotherapy and pharmacotherapy treatments for CBD. Uncontrolled effect sizes were calculated and meta-regression analyses were performed regarding treatment duration. Results A total of 29 articles met the inclusion criteria, which were divided into psychotherapy (n = 17) and pharmacotherapy treatments (n = 12). Of the 29 studies, only 5 studies have been tested under conditions of high methodological quality. Both forms of treatment had been evaluated in a haphazard manner across the stages of the hourglass model. Although large effects were demonstrated for group psychotherapy and pharmacotherapy, such evidence of effectiveness was undermined by poor study quality and risk of publication bias. Long-term CBD treatment was associated with improved outcome with pharmacotherapy, but not when delivering psychotherapy. Discussion Group psychotherapy currently appears the most promising treatment option for CBD. Poor methodological control and sporadic evaluation of specific treatments have slowed the generation of a convincing evidence base for CBD treatment. Defining the active ingredients of effective CBD treatment is a key research goal.

    The evaluation of consolidated cultivated land quality can provide basic information for how to perfect the program of land consolidation,as well as a reference for the dynamic monitoring of farmland quality in mining area. Based on the consultation and analysis of related literature,we can conclude that: firstly,most scholars focus on soil consolidation,while consider little about land use and economic condition. Secondly,foreign scholars usually use crop yields to judge the success of land consolidation,while domestic scholars have been evaluated the quality of consolidated cultivated land synthetically from several aspects,such as soil fertility,soil environmental quality,and farmland infrastructure conditions. Specifically,most of the evaluations are static,and indicators are different. Besides,the quality of consolidated cultivated land is generally low,and it lacks systematic research on technologies for improving quality of cultivated land consolidated from coal mining subsided land. It is concluded that future researches should focus on establishing scientific and feasible evaluation system to realize comparison of quality change in the dynamic course of " undisturbed-subsided-consolidated" cultivated land in coal mining areas,as well as technologies for improving quality of cultivated land consolidated from coal mining subsided land.

    Full Text Available Background: Sleep deprivation and drowsiness are very common among university students. The aim of this study was to examine the sleep quality and academic achievement among university students across all medical disciplines in Northwest of Iran. Methods: This study was based on data from a longitudinal study, the "Health and Lifestyle of University Students" (HeLiS. The Pittsburgh Sleep Quality Index (PSQI, a self-administered questionnaire consisting of general information about sleep quality, was completed by students during the first eight weeks of the first semester and academic achievement was assessed via Grade Point Average (GPA in the two semesters following the administration of the PSQI. Results: The mean age of students was 19.16±1.04 and the majority were female (64%. The mean overall score on the PSQI was 6.87±2.25; the majority of students (70% had a global PSQI score greater than 5, indicating they were poor sleepers. Only 28% reported getting over 7 hours of sleep. Female students had higher scores than male students in subjective sleep quality, which was statistically significant (2.15 vs. 1.95 respectively, P = 0.01; however, there was no difference between males and females on other component scores or on the global score. Results of a multiple regression model showed that PSQI score was a predictor of academic achievement (β=-.07, P=0.035, which implies that GPA will be lower among students whose quality of sleep is lower. Conclusion: Based on our sleep quality should be considered and assessed, and sleep hygiene should be promoted among medical university students in order to improve academic achievement.

    In recent years, the food safety and quality has always been a serious issue. Therefore, it is urgent to develop a rapid and widely available method to determine the quality of food. Due to high spectral resolution, good spectral selectivity and good ability of spectrogram analysis, the technology of two-dimensional (2D) correlation spectroscopy is an effective method for solving three major problems encountered by the conventional one-dimensional (1D) spectrum: low selectivity of the spectra, difficulty in extracting the information of the spectral feature and difficulty in spectrogram analysis. Therefore, 2D correlation spectroscopy, which is suited to distinguish similar samples hardly distinguished by the conventional 1D spectroscopy, has been successfully applied in many complex biological systems. The developmental process, the experimental way to obtain spectrum, the fundamental mathematical principle and the properties of 2D correlation spectroscopy were introduced in this paper. At the same time, it is pointed out that the origin of weak characteristic bands of substance can be verified in terms of the positive or negative corss peaks in synchronous 2D correlation spectrum combined with the existence or inexistence of corss peaks in asynchronous 2D correlation spectrum. The application of 2D near-infrared, mid-infrared, fluorescence, and raman correlation spectroscopy in the detection of food quality and adulteration, concentrated specifically on diary product, wine, oil, meat, honey, and rice were reviewed. Finally, the limitations and future development prospects were pointed out.

    Gefitinib, a tyrosine kinase inhibitor, is an effective treatment in advanced non-small cell lung cancer (NSCLC) patients with an activating mutation in the epidermal growth factor receptor (EGFR). Randomised clinical trials showed a benefit in progression free survival for gefitinib versus doublet chemotherapy regimens in patients with an activated EGFR mutation (EGFR M+). From a patient perspective, progression free survival is important, but so is health-related quality of life. Therefore, this analysis evaluates the Quality Adjusted progression free survival of gefitinib versus three relevant doublet chemotherapies (gemcitabine/cisplatin (Gem/Cis); pemetrexed/cisplatin (Pem/Cis); paclitaxel/carboplatin (Pac/Carb)) in a Dutch health care setting in patients with EGFR M+ stage IIIB/IV NSCLC. This study uses progression free survival rather than overall survival for its time frame in order to better compare the treatments and to account for the influence that subsequent treatment lines would have on overall survival analysis. Mean progression free survival for Pac/Carb was obtained by extrapolating the median progression free survival as reported in the Iressa-Pan-Asia Study (IPASS). Data from a network meta-analysis was used to estimate the mean progression free survival for therapies of interest relative to Pac/Carb. Adjustment for health-related quality of life was done by incorporating utilities for the Dutch population, obtained by converting FACT-L data (from IPASS) to utility values and multiplying these with the mean progression free survival for each treatment arm to determine the Quality Adjusted progression free survival. Probabilistic sensitivity analysis was carried out to determine 95% credibility intervals. The Quality Adjusted progression free survival (PFS) (mean, (95% credibility interval)) was 5.2 months (4.5; 5.8) for Gem/Cis, 5.3 months (4.6; 6.1) for Pem/Cis; 4.9 months (4.4; 5.5) for Pac/Carb and 8.3 (7.0; 9.9) for gefitinib.

    Groundwater quality research is extremely important for supporting the safety of the water supply and human health in arid and semi-arid areas of China. This review article was constructed to report the latest research progress of groundwater quality in western China where groundwater quality is undergoing fast deterioration because of fast economic development and extensive anthropogenic activities. The opportunities brought by increasing public awareness of groundwater quality protection were also highlighted and discussed. To guide and promote further development of groundwater quality research in China, especially in western China, ten key groundwater quality research fields were proposed. The review shows that the intensification of human activities and the associated impacts on groundwater quality in China, especially in western China, has made groundwater quality research increasingly important, and has caught the attention of local, national, and international agencies and scholars. China has achieved some progress in groundwater quality research in terms of national and regional laws, regulations, and financial supports. The future of groundwater quality research in China, especially in western China, is promising reflected by the opportunities highlighted. The key research fields proposed in this article may also inform groundwater quality protection and management at the national and international level.

    In this report, the National Marine Fisheries Service (NMFS), in collaboration with the Bonneville Power Administration (BPA), the Washington State Department of Fish and Wildlife (WDFW), and the US Fish and Wildlife Service (USFWS), presents research findings and guidelines for development and evaluation of innovative culture techniques to increase postrelease survival of hatchery fish. The Natural Rearing Enhancement System (NATURES) described in this report is a collection of experimental approaches designed to produce hatchery-reared chinook salmon (Oncorhynchus tshawytscha) that exhibit wild-like behavior, physiology, and morphology. The NATURES culture research for salmonids included multiple tests to develop techniques such as: raceways equipped with cover, structure, and natural substrates to promote development of proper body camouflage coloration; feed-delivery systems that condition fish to orient to the bottom rather than the surface of the rearing vessel; predator conditioning of fish to train them to avoid predators; and supplementing diets with natural live foods to improve foraging ability. The underlying assumptions are that NATURES will: (1) promote the development of natural cryptic coloration and antipredator behavior; (2) increase postrelease foraging efficiency; (3) improve fish health and condition by alleviating chronic, artificial rearing habitat-induced stress; and (4) reduce potential genetic selection pressures induced by the conventional salmon culture environment. A goal in using NATURES is to provide quality fish for rebuilding depleted natural runs.

    With the introduction of solid state light sources, the variety in emission spectra is almost unlimited. However, the set of standardized parameters to characterize a white LED light source, such as correlated color temperature (CCT) and CIE general color rendering index (Ra), is known to be limited and insufficient for describing perceived differences between light sources. Several characterization methods have been proposed over the past decades, but their contribution to perceived color quality has not always been validated. To gain more insight in the relevant characteristics of the emission spectra for specific applications, we have conducted a perception experiment to rate the attractiveness of three sets of objects, including fresh food, packaging materials and skin tones. The objects were illuminated with seven different combinations of Red, Green, Blue, Amber and White LEDs, all with the same CCT and illumination level, but with differences in Ra and color saturation. The results show that, in general, object attractiveness does not correlate well with Ra, but shows a positive correlation with saturation increase for two out of three applications. There is no clear relation between saturation and skin tone attractiveness, partly due to differences in preference between males and females. A relative gamut area index (Ga) represents the average change in saturation and a complementary color vector graphic shows the direction and magnitude of chromatic differences for the eight CIE-1974 test-color samples. Together with the CIE general color rendering index (Ra) they provide useful information for designing and optimizing application specific emission spectra.

    Full Text Available Depressive mood and other emotional symptoms are common in multiple sclerosis (MS. The patient-reported outcome version of the "Echelle d'Humeur Dépressive" (EHD-PRO aims to differentiate between two dimensions of depressive mood in people living with MS (PwMS.First, to compare EHD-PRO assessment and its two dimensions, lack of emotional control and emotional blunting, between a large sample of healthy controls (HCs and two samples of PwMS, relapsing-remitting MS (RRMS and primary progressive MS (PPMS; and second, to analyse the relationships between EHD-PRO scores with neurological disability, cognitive function, fatigue and health-related quality of life (HR-QOL.Regardless of their phenotype, PwMS had significantly higher EHD-PRO scores than HCs. EHD-PRO scores did not differ between the two MS groups. EHD-PRO scores did not correlate with disability and fatigue scores, disease duration or cognitive z scores. In RRMS, the lack of emotional control was independently associated with a decrease in HR-QOL.The EHD-PRO is able to easily detect depressive mood and to differentiate between two clinical dimensions, emotional blunting and lack of emotional control. The scale is sensitive and seems robust to confounding factors. Lack of emotional control seems to contribute significantly to altered HR-QOL in RRMS.

    Back pain is commonly experienced by pregnant women. Evidence suggests that progressive muscle relaxation (PMR) therapy, a complementary therapy widely used by pregnant women, may improve the physical and psychological outcomes of pregnancy. The aim of this study was to investigate the effects of PMR training accompanied by music on perceived pain and quality of life (QOL) in pregnant women with low back pain (LBP). This was a prospective randomized controlled trial. The study was designed to examine the effects of PMR accompanied by music on pregnant women with LBP. In total, 66 pregnant women were assigned randomly to a PMR group or a control group (33 women in each). A personal information form was used as a data collection tool; a visual analog scale was used for measuring pain; and the Short Form-36 was used to evaluate QOL. The control and intervention groups were comparable at baseline. Significant differences were observed between the 2 groups after 4 and 8 weeks of intervention. The intervention group showed significant improvement in all QOL subscales after the intervention. The intervention group, but not the control group, showed significant improvement in perceived pain after the intervention. The intervention group experienced a greater decrease in perceived pain and improved QOL than the control group. Our findings show that PMR accompanied by music may be an effective therapy for improving pain and QOL in pregnant women with LBP. Large randomized studies are recommended to confirm these results. © 2014 by the American College of Nurse‐Midwives.

    Full Text Available Background & aim: Decreased sleep quality is a common complaint during pregnancy. Relaxation is one of the non-pharmaceutical treatments for sleep disorders. Different techniques could have different impacts on various biological and mental stressors. Therefore, this study aimed to compare the effects of progressive muscle relaxation and guided imagery on the sleep quality of primigravida women. Methods:This three-group clinical trial was conducted on 100 primigravida women, referring to Mashhad health care centers in 2014. All women, who met the inclusion criteria, were randomly assigned to three groups: progressive muscle relaxation, guided imagery, and control groups. The intervention groups performed the exercises twice a day for a period of four weeks at home after two sessions of relaxation training (held during two weeks. Then, the quality of sleep was measured using Pittsburgh Sleep Quality Index. For data analysis, ANOVA, Kruskal-Wallis, paired t-test, and post-hoc test were performed, using SPSS version 11.5. Results: The total score of sleep quality and its components (except use of sleep medication was significantly lower after the intervention, compared to the pre-intervention period in progressive muscle relaxation and guided imagery groups (P

  6. Biochemical Characterization of Protein Quality Control Mechanisms during Disease Progression in the C22 Mouse Model of CMT1A

    Full Text Available Charcot–Marie–Tooth disease type 1A (CMT1A is a hereditary demyelinating neuropathy linked with duplication of the peripheral myelin protein 22 (PMP22 gene. Transgenic C22 mice, a model of CMT1A, display many features of the human disease, including slowed nerve conduction velocity and demyelination of peripheral nerves. How overproduction of PMP22 leads to compromised myelin and axonal pathology is not fully understood, but likely involves subcellular alterations in protein homoeostatic mechanisms within affected Schwann cells. The subcellular response to abnormally localized PMP22 includes the recruitment of the ubiquitin–proteasome system (UPS, autophagosomes and heat-shock proteins (HSPs. Here we assessed biochemical markers of these protein homoeostatic pathways in nerves from PMP22-overexpressing neuropathic mice between the ages of 2 and 12 months to ascertain their potential contribution to disease progression. In nerves of 3-week-old mice, using endoglycosidases and Western blotting, we found altered processing of the exogenous human PMP22, an abnormality that becomes more prevalent with age. Along with the ongoing accrual of misfolded PMP22, the activity of the proteasome becomes compromised and proteins required for autophagy induction and lysosome biogenesis are up-regulated. Moreover, cytosolic chaperones are consistently elevated in nerves from neuropathic mice, with the most prominent change in HSP70. The gradual alterations in protein homoeostatic response are accompanied by Schwann cell de-differentiation and macrophage infiltration. Together, these results show that while subcellular protein quality control mechanisms respond appropriately to the presence of the overproduced PMP22, with aging they are unable to prevent the accrual of misfolded proteins.

    The aim of this cross-sectional study was to evaluate the impact of dental caries on the quality of life of preschool children and their parents/caretakers, with an emphasis on the type of tooth and stage of progression. A randomly selected sample of preschool children, 3-5 yrs of age, underwent an oral examination for the assessment of dental caries using the International Caries Detection and Assessment System II (ICDAS II) criteria. Parents/caretakers answered two questionnaires, one on the oral health-related quality of life (OHRQoL) of the child [the Early Childhood Oral Health Impact Scale (ECOHIS)], and the other on the socio-economic characteristics of the family. Statistical analyses were performed using the chi-square test, Kruskal-Wallis test, Mann-Whitney U-test, and Poisson regression. A total of 451 preschool children participated in the study. The majority of carious lesions exhibited severe decay (60.6%) and were found in both anterior (incisors/canines) and posterior (molars) teeth. The final Poisson model revealed negative impacts on quality of life from more advanced stages of dental caries, both in incisors/canines and molars. Child's age and household income were also associated with impact on quality of life. Carious lesions in more advanced stages of progression in anterior and posterior teeth were associated with a negative impact on the quality of life of preschool children.

    The West Bank in the Palestinian Territories is undergoing an epidemiologic transition. We provide a general description of mortality from all causes, focusing on chronic disease mortality in adults. Mortality data analyzed for our study were obtained from the Palestinian Ministry of Health in the West Bank for 1999 through 2003. Individual information was obtained from death notification forms. A total of 27,065 deaths were reported for 1999 through 2003 in the West Bank, Palestinian Territories. Circulatory diseases were the main cause of death (45%), followed by cancer (10%) and unintentional injuries (7%). Among men, the highest age-standardized mortality rates (ASMRs) were due to diseases of the circulatory system, cancer, and unintentional injuries. Among women, the highest ASMRs were due to circulatory disease, cancer, and diabetes mellitus. Of the circulatory diseases, the highest ASMRs for men were due to acute myocardial infarction and cerebrovascular disease. ASMRs attributable to circulatory system diseases were similar for women. Lung cancer was the largest cause of cancer mortality for men; breast cancer was the largest cause for women. Because of the high mortality rates, the risk factors associated with chronic diseases in the Palestinian Territories must be ascertained. Medical and public health policies and interventions need to be reassessed, giving due attention to this rise in modern-day diseases in this area.

    To examine why the Framework Convention on Tobacco Control did not include an explicit trade provision and delineate the central arguments in the debate over trade provision during the negotiations. Triangulate interviews with participants in the FCTC negotiations, the FCTC negotiations documents, and tobacco industry documents. An explicit FCTC trade provision on relation between international trade and public health became a contentious issue during the negotiations. As a result, two conflicting positions, health-over-trade and opposition to health-over-trade emerged. Opposition to explicit trade language giving health priority was by both tobacco industry and countries that generally supported strong FCTC provisions because of concerns over 'disguised protectionism' and setting a precedent whereby governments could forfeit their obligations under pre-existing treaties. Owing to lack of consensus among political actors involved in the negotiations, a compromise position eliminating any mention of trade emerged, which was predicated on belief among some in the public health community that public health would prevail in future trade versus health conflicts. The absence of an explicit FCTC trade provision was due to a political compromise rather than the impact of international trade agreements and decisions on public health and lack of consensus among health advocates. This failure to include an explicit trade provision in the FCTC suggests that the public health community should become more involved in trade and health issues at all levels of governance and press the FCTC Conference of the Parties for clarification of this critical issue.

However, contextual factors, such as team functioning, leadership, and organizational support, can vary significantly across teams and affect the level of implementation success. Yet, the science for measuring context is immature. The goal of this study is to validate measures from a short instrument tailored to track dynamic context and progress for a team-based quality improvement (QI intervention. Methods Design: Secondary cross-sectional and longitudinal analysis of data from a clustered randomized controlled trial (RCT of a team-based quality improvement intervention to reduce central line-associated bloodstream infection (CLABSI rates in intensive care units (ICUs. Setting: Forty-six ICUs located within 35 faith-based, not-for-profit community hospitals across 12 states in the U.S. Population: Team members participating in an ICU-based QI intervention. Measures: The primary measure is the Team Check-up Tool (TCT, an original instrument that assesses context and progress of a team-based QI intervention. The TCT is administered monthly. Validation measures include CLABSI rate, Team Functioning Survey (TFS and Practice Environment Scale (PES from the Nursing Work Index. Analysis: Temporal stability, responsiveness and validity of the TCT. Results We found evidence supporting the temporal stability, construct validity, and responsiveness of TCT measures of intervention activities, perceived group-level behaviors, and barriers to team progress. Conclusions The TCT demonstrates good measurement reliability, validity, and responsiveness. By having more validated measures on implementation context, researchers can more readily conduct rigorous studies to identify contextual variables linked to key intervention and patient outcomes and strengthen the evidence base on successful spread of efficacious team-based interventions.

    Water quality is an emergent property of a complex system comprised of interacting microbial populations and introduced microbial and chemical contaminants. Studies leveraging next-generation sequencing (NGS) technologies are providing new insights into the ecology of microbially mediated processes that influence fresh water quality such as algal blooms, contaminant biodegradation, and pathogen dissemination. In addition, sequencing methods targeting small subunit (SSU) rRNA hypervariable regions have allowed identification of signature microbial species that serve as bioindicators for sewage contamination in these environments. Beyond amplicon sequencing, metagenomic and metatranscriptomic analyses of microbial communities in fresh water environments reveal the genetic capabilities and interplay of waterborne microorganisms, shedding light on the mechanisms for production and biodegradation of toxins and other contaminants. This review discusses the challenges and benefits of applying NGS-based methods to water quality research and assessment. We will consider the suitability and biases inherent in the application of NGS as a screening tool for assessment of biological risks and discuss the potential and limitations for direct quantitative interpretation of NGS data. Secondly, we will examine case studies from recent literature where NGS based methods have been applied to topics in water quality assessment, including development of bioindicators for sewage pollution and microbial source tracking, characterizing the distribution of toxin and antibiotic resistance genes in water samples, and investigating mechanisms of biodegradation of harmful pollutants that threaten water quality. Finally, we provide a short review of emerging NGS platforms and their potential applications to the next generation of water quality assessment tools.

    Cardiovascular diseases have surpassed infectious disorders to become the leading cause of morbidity and mortality in India.(1) A national-level registry comprehensively documenting the current-day prevalence of cardiovascular risk factors and disease burden among patients seeking care in the outpatient setting in India is currently non-existent. With a burgeoning urban population, the cardiovascular disease burden in India is set to skyrocket, with an estimated 18 million productive years of life lost by 2030.(2) While there are limited quality improvement registries in India, for example, the Kerala acute coronary syndrome and Trivandrum heart failure registries, their focus is on in-patient care quality improvement, while the vast majority of patients with cardiovascular diseases worldwide, including India, interact with the health care system in the outpatient setting.(3,4) Recognizing this unmet need, the American College of Cardiology partnered with local stakeholders in India to establish India's first outpatient cardiovascular disease performance measurement initiative in 2011, the PINNACLE (Practice Innovation and Clinical Excellence) India Quality Improvement Program (PIQIP).(5) This manuscript discusses the inception of the PIQIP registry, the progress it has made and challenges thus far, and its future direction and the promise it holds for cardiovascular care quality improvement in India.

    The production of biopharmaceuticals requires highly sophisticated, complex cell based processes. Once a process has been developed, acceptable ranges for various control parameters are typically defined based on process characterization studies often comprising several dozens of small scale bioreactor cultivations. A lot of data is generated during these studies and usually only the information needed to define acceptable ranges is processed in more detail. Making use of the wealth of information contained in such data sets, we present here a methodology that uses performance data (such as metabolite profiles) to forecast the product quality and quantity of mammalian cell culture processes based on a toolbox of advanced statistical methods. With this performance based modeling (PBM) the final product concentration and 12 quality attributes (QAs) for two different biopharmaceutical products were predicted in daily intervals throughout the main stage process. The best forecast was achieved for product concentration in a very early phase of the process. Furthermore, some glycan isoforms were predicted with good accuracy several days before the bioreactor was harvested. Overall, PBM clearly demonstrated its capability of early process endpoint prediction by only using commonly available data, even though it was not possible to predict all QAs with the desired accuracy. Knowing the product quality prior to the harvest allows the manufacturer to take counter measures in case the forecasted quality or quantity deviates from what is expected. This would be a big step towards real-time release, an important element of the FDA's PAT initiative. © 2015 American Institute of Chemical Engineers.

    In early 1999, primary treatment and discharge of sewage from Tijuana, Mexico (approximately 95 million liters per day) began through South Bay Ocean Outfall (SBOO) into the ocean 4.3 km offshore. In this study, statistical comparisons were made of the bacterial water quality (total and fecal coliforms and enterococci densities) of the ocean, both before and after discharge of sewage to the SBOO began, so that the effect of this ocean discharge on nearshore ocean water quality could be quantitatively assessed. The frequency of exceedence of bacterial indicator thresholds was statistically analyzed for 11 shore (surfzone) stations throughout US and Mexico using the Fisher's exact test, for the years before (1995-1998) as compared to after the SBOO discharge began (1999-2003). Only four of the 11 shoreline stations (S2, S3, S11, and S12) showed significant improvement (decreased frequency of exceedence of bacterial indicator thresholds) after SBOO discharge began.

    World-largest macroalgal blooms (MAB) caused by Ulva prolifera outbreak every summer in the Yellow Sea since 2007, which bring potential damage to regional aquatic environment and economic. Evaluation of the evolution of historic eutrophication status is of importance for exploring the reasons of the blooms and further management. In this study, a novel nutrient pollution index weighted by area (AWCPI-NP) and ocean color data were proposed to assess temporal changes in eutrophication status in the in the Yellow Sea basin, and significant shifts were observed from the pre-MAB phase (2001-2006) to MAB phase (2007-2012): the average AWCPI-NP was higher than that in the pre-MAB phase (2001-2006) by about 45%; Chlorophyll a concentration (Chl-a), an indicator of eutrophication, increased by about 15% in the bloom region. Meanwhile, in the Jiangsu Shoal, the origin place of the floating macroaglae, the annual in-situ nutrient concentrations increased rapidly from 2000 to 2011. This new finding of progressive eutrophication behind the MAB implies that the large scale of MAB in the Yellow Sea might be primarily linked to eutrophication. Accordingly, we suggest policy- makers include this new knowledge when countermeasures are considered to control this hazard.

    In ALS it would be expected that quality of life (QoL) would be decreased. However, studies to date show diverging results. Our study focuses on how ALS affects QoL on the different domains of the SF-36 cross-sectionally and during progression. The method used was a prospective cohort study, with assessments at baseline, at six months, and at one year. Patients were included with possible, probable or definite ALS according to the revised El Escorial criteria and were between 30 and 70 years of age. ALS functional rating scale was used to establish disease status, SF-36 as QoL scale. At baseline 73 completed ALSFRS forms were available and 62 completed SF-36 forms. The ALSFRS showed disease progression. SF-36 scores showed lower QoL scores of persons with ALS compared to the general population both in cross-sectional and longitudinal aspects in the domains of Physical Functioning, Role Physical, and Social Functioning, but similar compared with the general population in the Mental Health and Role Emotional domains. This study shows deteriorating physical health but stable mental health, thereby illustrating the diverging correlations between ALS severity and HRQoL. The diverging pattern of physical and mental health suggests a frame-shift in the experience of HRQoL.

    卵母细胞质量是影响人类辅助生殖技术(ART)成功率的关键因素之一。目前临床数据和基础研究结果均显示,部分ART促排卵过程中获得的卵母细胞在纺锤体组装、基因表达、细胞器形态与功能等方面均存在一定的异常,这可能导致形成的胚胎发育率降低,并对子代长期健康产生一定的风险。因此,鉴定出最具发育潜能的卵母细胞,能够优化移植过程,改善ART结局,降低ART风险。然而,在体外受精-胚胎移植(IVF-ET)卵母细胞或胚胎选择时,缺乏可靠而客观的预测卵母细胞发育潜能的指标,妨碍了该技术的临床应用。综述现今用于评估卵母细胞质量的方法,以期为临床应用提供一定的依据与指导。%Oocyte quality is one of the key factors that affect the efficiency of human assisted reproductive technology (ART). Current clinical data and basic research results showed that a part of oocytes from ART were abnormal in spindle assembly, gene expression, organelle morphology and function, etc. Those abnormalities could lead to lower rate of embryo development and some long-term health risks of offspring. Thus, the identification of the most competent oocyte can optimize translation process and improve the outcome of ART. However, the lack of reliable and objective predictive marker for oocyte/embryo selection during IVF-ET greatly hindered the clinical application of this technology. This article reviewed the existing methods to evaluate the oocyte quality, providing us some basis and guidance for clinical practice.

    The knowledge of error rates is essential in all clinical laboratories as it enables them to accurately identify their risk level, and compare it with those of other laboratories in order to evaluate their performance in relation to the State-of-the-Art (i.e. benchmarking) and define priorities for improvement actions. Although no activity is risk free, it is widely accepted that the risk of error is minimized by the use of Quality Indicators (QIs) managed as a part of laboratory improvement strategy and proven to be suitable monitoring and improvement tools. The purpose of QIs is to keep the error risk at a level that minimizes the likelihood of patients. However, identifying a suitable State-of-the-Art is challenging, because it calls for the knowledge of error rates measured in a variety of laboratories throughout world that differ in their organization and management, context, and the population they serve. Moreover, it also depends on the choice of the events to keep under control and the individual procedure for measurement. Although many laboratory professionals believe that the systemic use of QIs in Laboratory Medicine may be effective in decreasing errors occurring throughout the total testing process (TTP), to improve patient safety as well as to satisfy the requirements of International Standard ISO 15189, they find it difficult to maintain standardized and systematic data collection, and to promote continued high level of interest, commitment and dedication in the entire staff. Although many laboratories worldwide express a willingness to participate to the Model of QIs (MQI) project of IFCC Working Group "Laboratory Errors and Patient Safety", few systematically enter/record their own results and/or use a number of QIs designed to cover all phases of the TTP. Many laboratories justify their inadequate participation in data collection of QIs by claiming that the number of QIs included in the MQI is excessive. However, an analysis of results suggests

    To explore the effects of combined intervention with education and progressive muscle relaxation (PMR) on quality of life (QoL), functional disability, and positive symptoms of patients with acute schizophrenia. This randomized controlled study took place in an acute schizophrenia ward in Changsha, China. Sixty-four patients with acute schizophrenia were randomly assigned to four groups: control, education, PMR, and education plus PMR. QoL was assessed with the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form. Functional disability was assessed with the Sheehan Disability Scale. Severity of positive schizophrenia symptoms was assessed with the Scale for the Assessment of Positive Symptoms. All patients were evaluated at baseline (within 72 hours before the interventions) and at the end of weeks 5 (when the interventions ended) and week 15 (a 10-week follow-up after the interventions). The sociodemographic and clinical characteristics of all four study groups were similar at baseline. Repeated-measures analysis of variance showed significant differences among the interventions in improving QoL, functional disability, and positive symptoms over time in the patients. Education and PMR alone resulted in sustained improvement of QoL during the intervention period and a 10-week follow-up but had no significant effects on functional disability or positive schizophrenia symptoms. In contrast, combined intervention with education and PMR showed better effects on improving QoL than did education or PMR alone throughout the 15-week study. It also statistically significantly improved functional disability and positive schizophrenia symptoms during the intervention period and led to sustained improvement of functional disability during the 10-week follow-up. A combined intervention with education and PMR is effective in improving QoL, functional disability, and positive symptoms in patients with acute schizophrenia. The combined intervention model could be a

    Full Text Available Abstract Background Gleason scoring has experienced several modifications during the past decade. So far, only one study has compared the prognostic abilities of worst (WGS and overall (OGS modified Gleason scores after the ISUP 2005 conference. Prostatic needle biopsies are individually paraffin-embedded in 57% of European pathology laboratories, whereas the rest of laboratories embed multiple (2 - 6 biopsies per one paraffin-block. Differences in the processing method can have a far-reaching effect, because reporting of the Gleason score (GS is different for individually embedded and pooled biopsies, and GS is one of the most important factors when selecting treatment for patients. Methods The study material consisted of needle biopsies from 236 prostate cancer patients that were endocrine-treated in 1999-2003. Biopsies from left side and right side were embedded separately. Haematoxylin-eosin-stained slides were scanned and analyzed on web-based virtual microscopy. Worst and overall Gleason scores were assessed according to the modified Gleason score schema after analyzing each biopsy separately. The compound Gleason scores (CGS were obtained from the original pathology reports. Two different grade groupings were used: GS 6 or less vs. 7 vs. 8 or above; and GS 7(3 + 4 or less vs. 7(4 + 3 and 8 vs. 9-10. The prognostic ability of the three scoring methods to predict biochemical progression was compared with Kaplan-Meier survival analysis and univariate and multivariate Cox regression analyses. Results The median follow-up time of the patients was 64.5 months (range 0-118. The modified GS criteria led to upgrading of the Gleason sums compared to the original CGS from the pathology reports 1999-2003 (mean 7.0 for CGS, 7.5 for OGS, 7.6 for WGS. In 43 cases WGS was > OGS.

As informações sobre as angioplastias coronárias provieram do banco de Autorizações de Internações Hospitalares da Secretaria de Estado de Saúde do Estado do Rio de Janeiro. As taxas de letalidade foram estimadas segundo faixas etárias, sexo, diagnósticos e hospitais. A letalidade geral foi de 1,9% em 8.735 angioplastias coronárias. A taxa mais baixa ocorreu nas anginas (0,8%, as mais elevadas nos infartos agudos do miocárdio (6% e em outros diagnósticos (7%. A letalidade foi menor nas mulheres na faixa etária entre 50 e 69 anos, e a partir dos setenta anos foi quase três vezes maior que a dos mais jovens (de 1,4 a 4%, em ambos os sexos. Ocorreu grande variabilidade entre as taxas de letalidade nas angioplastias coronárias nos diferentes hospitais (entre 0 e 6,5%. Portanto, é necessário acompanhar de modo contínuo a adequação da utilização da angioplastia coronária. Em conclusão, a performance deste procedimento no âmbito da modalidade de atenção pelo SUS nos hospitais, dentro do período estudado, não foi satisfatória.This study analyzes hospital case fatality associated with percutaneous transluminal coronary angioplasties (PTCA covered by the Brazilian Unified National Health System (SUS and performed in hospitals in the State of Rio de Janeiro from 1999 to 2003. PTCA data were obtained from the State Health Department's database on Authorizations for Hospital Admissions. Case fatality rates were estimated according to age, gender, diagnosis, and hospital. Overall case fatality was 1.9% in 8,735 PTCAs. The lowest rate was associated with angina (0.8% and the highest rates with acute myocardial infarction (6% and other diagnoses (7%. In the 50-69-year bracket, case fatality was higher in women. In the over-70 group, it was almost three times that of the youngest group (4% versus 1.4%. There was great variability among PTCA case fatality rates in different hospitals (from 0 to 6.5%. Ongoing monitoring of PTCAs is thus necessary in clinical practice. In conclusion, PTCA performance was still unsatisfactory under the Unified National Health System.

    Equine herpesvirus type 1(EHV-1)-associated myeloencephalopathy (EHM) is a rare disease affecting the central nervous system and, in particular, the spinal cord of horses. Epidemiologic data are limited, and usually are restricted to the description of a single outbreak. During an observational period of 4 years, we evaluated 9 outbreaks of EHM in The Netherlands. A risk factor analysis was done on the data from 6 outbreaks. Findings were: regular appearance of EHM outbreaks in The Netherlands (2-3/y); strong association of EHM with season; and risk factors, such as breed, sex, age, and fever. Female horses, aged horses, and specific breeds were at greater risk to develop severe neurologic disease. Other breeds and horses EHM during these outbreaks. It was concluded that breed variation, in addition to the presence of a specific EHV-1 strain, and environmental factors influence an outbreak of EHM on a premise.

    Environmental toxin/s is alleged to be the contributory factor for the chronic kidney disease of unknown etiology (CKDu) in Sri Lanka. The potential of drinking water as a medium for the nephrotoxic agents in the affected subjects has been comprehensively discoursed in the recent past. The present study was aimed to assess the effect of replacing the habitual drinking water on the kidney function of CKDu patients residing in the North Central Province of Sri Lanka: METHODS: An interventional study was carried out to assess the disease progression rate of a CKDu population whose habitual drinking water was replaced by bottled spring water certified by Sri Lanka Standard (SLS) for a period of 18 month along with a population of CKDu patients who continued with their usual drinking water. Kidney function of subjects in both groups were monitored in terms of blood pressure, serum creatinine, serum calcium, serum phosphorus, hemoglobin, estimated glomerular filtration rate and urinary protein at 6 months intervals during the intervention and follow up periods. Diminished disease progression rate was observed in CKDu patients in the intervention group when compared with the non- intervention group based on serum creatinine, Hb, estimated glomerular filtration rate and urinary protein levels. Extensive interventional studies are required to generalize effect of drinking water on CKDu population. The habitual drinking water is likely to be a contributory factor towards the progression of the disease. This article is protected by copyright. All rights reserved.

    It is necessary to evaluate the soil quality status of black farmland in order to use it rationally and maintain its sustainability. So the author summarized researches on soil quality indication of black farmland from the 1980s, including physical indicators, chemical indicators and biological indicators. Soil physical indicators and chemical indicators of black farmland started to research earlier, and now they has become much mature. On the other hand, the research on biological indicators (including microorganisms, enzymes, soil animals) appeared relatively late. However, it' s worth mentioning that the soil biological indicators could be more rapid to evaluate the soil quality of different agriculture processes and be more sensitive to land utilization. Nevertheless, up until now, the validation including soil biological indicators as a universal soil quality criterion has still been under discussion. In the future, people should integrate not only biological indicators, but also modern analysis technology to detect soil quality so as to provide the basic data for soil quality testing and rational development of black farmland.%为了合理利用黑土,维持黑土的可持续性,有必要对农田黑土的质量现状进行评价.因此,综述了20世纪80年代至今农田黑土的质量指标的研究状况,包括土壤的物理指标、化学指标和生物学指标,其中农田黑土物理指标和化学指标研究较早,研究方法已趋于成熟,而生物学指标(包括微生物、酶,土壤动物)研究起步较晚,但生物学指标能较迅速地评价不同农业过程的土壤质量,对土地利用的变化较为灵敏,但到目前为止农田黑土质量评价体系中还没有利用生物学指标的统一标准.在农田黑土质量指标的研究中除了要结合生物指标外,还需要利用现代分析技术快速灵敏的检测土壤质量,这才能为农田黑土的质量检测及合理开发提供基础数据.

    Jiangsu Agency for Educational Evaluation adopts a comprehensive progress report card as an assessment tool in its recent institutional quality audit of two institutions of the Province. The report card consists of 10 dimen⁃sions of internal quality assurance plus 5 levels of attainment for each dimension. The status of the internal quality assurance of an audited institution is interpreted by a certain attainment level of each dimension, and it can also be expressed by a coordinates curve. In the two cases of institutional quality audit, the comprehensive progress report card has served as a useful tool for helping the auditors to make their judgments about the status of the internal quality assurance system of an audited institution. It can also be used as a framework for guiding institutions in data mining and conducting follow⁃up activities of continuous improvement.%根据国家评估改革方案,地方院校的审核评估下放至省级组织实施。某省在审核评估中试用了综合评价卡,作为写实性评估结论意见的一种标识和呈现方式。通过对院校内部质量保障状态的十个维度和各维度的五个达标程度的定性描述,并以坐标和曲线的形式直观表达院校所处的位置。这一创新实践既避免了以往教学水平评估的“优良中差”分等评估的弊端,也规避了新一轮教学工作审核评估结论出现过于大而化之、无法全面客观反映院校的整体实情的风险,受到专家的普遍肯定。未来拟帮助院校更加深入地理解和使用好综合评价卡,为其强化内部质量保障机制打造一个切实可行的专业工具。

    procedures. One man who was well aware of the role of nanostructured catalysts in the progress of material science research was the late Ulrich Gösele, director at the Max-Planck-Institut für Mikrostrukturphysik Halle, who passed away at the age of 60 on 8 November, 2009. Ulrich Gösele published over 750 papers of premium calibre research that have collectively been cited over 20,000 times. His research output includes a cornucopia of excellent work published in Nanotechnology, amongst which are a number of papers detailing the deft manipulation of nanocatalysts to control the quality and structure of nanomaterials [5-8]. Ulrich Gösele was a pioneer in nanoscience. In 1991, when the nanotechnology revolution was little more than a portentous rumble, he published a seminal report examining the effect of quantum confinement on the optical properties of silicon nanowires [9]. While we lament the loss to the community, we have much to celebrate in the insights his legacy has provided for the progress of materials science. It would be unwise to assume that science will or can ultimately advance in such a way as to allow ample means to indulge an unrestrained appetite for consumerism and energy consumption. As with most things, a balanced approach, considering solutions to the problem from many angles, seems sensible. Nonetheless, a browse through the latest literature leaves much cause for optimism for the positive role science can play in improving and sustaining our lifestyle.

    2007-01-01

    BACKGROUND:Pancreas transplantation (PT) has proved effective but it is associated with a high risk of surgical complications and technical failure. Duct management and venous drainage are identiifed as major issues. Improvements in immunosuppression and prophylaxis greatly have contributed to surgical progress. DATA SOURCES: A literature search of the PubMed database (1996-2005) was conducted and research articles on PT reviewed. RESULTS: More than 23 000 PTs have been performed throughout the world. The majority (83%) were performed in combination with kidney transplantation [simultaneous pancreas-kidney transplantation (SPK)]. Pancreas graft survival rates at one year were 85% for 2001-2003 SPK cases, 79% for pancreas after kidney transplantation (PAK) cases, and 76% for pancreas transplantation alone (PTA) cases. For the 1999-2003 cases, enteric drainage was done in 79% of the SPK cases and bladder drainage in 21%. Patient survival rates, pancreas and kidney graft survival rates, and pancreas graft immunological failure rates did not differ signiifcantly in enteric versus bladder drainage cases. All the available data fail to demonstrate a deifnitive advantage of portal drainage over systemic drainage. From 1993 to 2002, the use of rabbit antithymocyte globulin increased from 0 to 37%;the use of daclizumab increased from 0 to 16%;and the use of basiliximab increased from 0 to 25%. In 1993, 98%of SPK recipients received cyclosporine;but this was decreased to 9% in 2002. Tacrolimus (FK506) usage has increased from 0 (1993) to 87%(2002) of SPK recipients. Sirolimus (SIR) usage has increased from 0 (1993) to 18%(2002) of SPK recipients. CONCLUSIONS: PT remains an effective therapy for treatment of type Ⅰ diabetes mellitus. Enteric drainage is currently predominant in SPK, but bladder drainage is still largely used. Portal drainage is as safe as systemic drainage, but there is still no convincing evidence about whether it is immunologically or metabolically

    Impaired mobility is a cardinal feature of multiple sclerosis (MS) and is rated by people with MS as their highest priority. By the secondary progressive phase, balance, mobility and physical activity levels are significantly compromised; an estimated 70% of people with secondary progressive MS fall regularly. Our ongoing research has systematically developed 'Balance Right in MS' (BRiMS), an innovative, manualised 13-week guided self-management programme tailored to the needs of people with MS, designed to improve safe mobility and minimise falls. Our eventual aim is to assess the clinical and cost effectiveness of BRiMS in people with secondary progressive MS by undertaking an appropriately statistically powered, multi-centre, assessor-blinded definitive, randomised controlled trial. This feasibility study will assess the acceptability of the intervention and test the achievability of running such a definitive trial. This is a pragmatic multi-centre feasibility randomised controlled trial with blinded outcome assessment. Sixty ambulant people with secondary progressive MS who self-report two or more falls in the previous 6 months will be randomly allocated (1:1) to either the BRiMS programme plus usual care or to usual care alone. All participants will be assessed at baseline and followed up at 15 weeks and 27 weeks post-randomisation. The outcomes of this feasibility trial include:Feasibility outcomes, including trial recruitment, retention and completionAssessment of the proposed outcome measures for the anticipated definitive trial (including measures of walking, quality of life, falls, balance and activity level)Measures of adherence to the BRiMS programmeData to inform the economic evaluation in a future trialProcess evaluation (assessment of treatment fidelity and qualitative evaluation of participant and treating therapist experience). The BRiMS intervention aims to address a key concern for MS service users and providers. However, there are several

    Full Text Available Within the framework of growing concern for analyzing the quality of young democracies, this article focuses on the Paraguayan case. A democracy sometimes neglected by the academic literature. However, Paraguay is drawing attention as a consequence of Colorado’s Party defeat (in office since 1947 in the 2008 presidential election. A theoretical and methodological thinking about the concept of the quality of democracy together with an empirical research have been done in this article. Five essential dimensions have been taken into consideration: political rights and civil liberties; rule of law; accountability; responsiveness and political participation. The main conclusion is that Paraguay has a low quality democracy, far away from the rest of Latin American countries. This statement is backed up by three different explanations that are, at the same time, interlinked. These are the following: socioeconomic factors, features of its own political institutions (above all, the widespread clientelism and, finally, political parties’ interests and strategies.En el marco de una preocupación cada vez mayor por analizar la calidad de las nuevas democracias, este artículo se ocupa de examinar el caso de Paraguay. Se trata de una democracia poco atendida en la literatura especializada aunque su interés está creciendo como consecuencia de la derrota electoral del Partido Colorado (en el poder desde 1947 en las presidenciales de abril de 2008. Para llevar a cabo este trabajo, se parte de una reflexión teórica y metodológica en torno a la noción y la medición empírica de la calidad democrática. Al realizar el análisis de la democracia paraguaya se atiende a cinco dimensiones fundamentales: derechos políticos y libertades civiles, Estado de Derecho, rendición de cuentas, responsiveness y participación. La conclusión general es que es una democracia de baja calidad, distanciada del promedio latinoamericano. Para explicar este bajo nivel de

    Chemotherapy and its associated side effects can induce the disruption of circadian rest-activity rhythm and may have negative consequences on health-related quality of life (HRQoL) of cancer patients. In the current study, repeated-measures cross-sectional design was implemented to determine the status of circadian rest-activity rhythm and to assess the HRQoL of newly diagnosed female breast cancer patients those were planned to receive six cycles of chemotherapy. Rest activity and HRQoL were assessed in twenty-five patients during chemotherapy cycles 1st (C1), 3rd (C3), and 6th (C6) immediately after they reported to the outdoor ward of the Regional Cancer Center, Pt. J.N.M. Medical College, Dr. B.R. Ambedkar Memorial Hospital, Raipur, India. Wrist actigraphs for consecutive spans of 3-4 days were used to record the rest-activity rhythm, and its parameters were computed with the help of Cosinor Rhythmometry. Quality of life (QoL) parameters were assessed using EORTC QLQ-C30 and QLQ-BR23. Results revealed that average scores of all rhythm parameters, such as MESOR, amplitude, acrophase, rhythm quotient, circadian quotient, peak activity, dichotomy index, and autocorrelation coefficient; and all functional scales of QLQ-C30, such as physical, role, emotional, cognitive, and social, and global quality of life statistically significantly decreased with the increasing number of chemotherapy cycles (C1 to C3 and C6). Scores of symptom scales of QLQ-C30, such as fatigue, pain, dyspnoea, insomnia, appetite loss, and diarrhea increased significantly from C1 to C6. Among the QLQ-BR23 scales, scores of sexual functioning, sexual enjoyment, breast symptoms, and arm symptoms significantly decreased, whereas scores of systemic therapy side effects, and upset by hair loss significantly increased across the chemotherapy cycles. We conclude that rest-activity rhythm disrupted and HRQoL of breast cancer patients worsened along the increasing number of chemotherapy cycles. We

    Esch, G.W.; Hazen, T.C.

    1978-07-01

    The implications from these studies are varied, sometimes clear and sometimes less so, for many of the results have raised new and even more critical questions. Thus, our data clearly show that Aeromonas hydrophila is the etiological agent for red-sore disease. Furthermore, they suggest that the effects of temperature are twofold, first in increasing the density of the pathogen in the water column and then in affecting the physiology of the host organism to such an extent as to increase the probability of acquiring the pathogen. On the other hand, organic loading, suggested by other investigators as being important in red-sore disease, was not identified as being significant in the present study. However, if organic loading, or any of its consequences, can be shown to induce stress, then it may be as important in other systems as temperature is in Par Pond. Thus it is quite conceivable that it (organic loading), or some other water quality parameter, may create conditions conducive to increasing densities of A. hydrophila while simultaneously producing water quality characteristics which would lead to stress in fish, and then to increasing the probability of fish acquiring red-sore disease. An enigmatic observation (see Hazen, 1978, for details) is that A. hydrophila has been recovered from a variety of habitats throughout the U.S., yet red-sore disease is known to occur only in the southeast. This peculiar distribution pattern raises several important questions regarding the epizootiology of red-sore, not the least of which is the possibility of there existing differentially virulent strains of A. hydrophila and/or more or less susceptible populations of potential hosts in various parts of the country. Other significant questions are related to the variability in amplitude of red-sore disease from one year to the next among bass in Par Pond, the mode of entry of the pathogen into largemouth bass, and the basic, cellular mechanisms of stress in largemouth bass.

    Between 1990 and 1995 the U.S. Department of Energy (DOE) and the National Center for Improving Science Education (National Center) developed a system for ongoing evaluation of K-12 educational programs in the DOE-supported national energy Laboratories. As part of the formative evaluation component of this collaborative endeavor, field staff in the Laboratories began creating profiles of their programs. However, many individuals within DOE Headquarters were not familiar with this profiling process and were unprepared to use the valuable information that the profiles generated. This manual was produced to orient Headquarters staff to profiling. It focuses on how Headquarters staff can use the profiling process to help their funded programs establish and/or maintain high quality. Its purpose, then, is not to train Headquarters staff to become proficient in profiling, but to show them how to draw on the Laboratories` use of profiling to bring about program improvement. Profiling is the process of systematically examining and describing a program`s elements against a set of components that define Effective Practice. The instrument used to capture the data for analysis is called a template, and most of this manual focuses on the templates and how to read and interpret them. However, since it is important to understand these data in context, the authors also describe what should accompany each template in a complete profiling packet and offer guidelines for reviewing complete packets and providing feedback to program managers. This document consists of Support Materials for the manual: exercise answer keys; templates; guidelines for reviewing templates; a complete profiling packet; guidelines for the trainer.

    Petrographic analysis combined with various techniques, such as thin section identification, fluid inclusions, isotopic data, petro-physical property testing and oil testing results, was used to study diagenetic evolution and its effect on reservoir-quality of fan delta reservoirs of Es4s in the Bonan sag. The diagenesis is principally characterized by strong compaction, undercompaction, multi-phase of dissolution and cementation. Compaction played a more important role than cementation in destroying the primary porosity of the sandstones. The reservoirs have experienced complicated diagenetic environment evolution of “weak alkaline− acid−alkalinity−acid−weak alkalinity” and two-stage of hydrocarbon filling. The diagenetic sequences are summarized as “early compaction/early pyrite/gypsum/calcite/dolomite cementation→feldspar dissolution/the first stage of quartz overgrowth→ early hydrocarbon filling→quartz dissolution/anhydrite/Fe-carbonate cementation→Fe-carbonate dissolution/feldspar dissolution/ the second stage of quartz overgrowth→later hydrocarbon filling→later pyrite cementation. In the same diagenetic context, the diagenetic evolution processes that occurred in different sub/micro-facies during progressive burial have resulted in heterogeneous reservoir properties and oiliness. The braided channel reservoirs in fan delta plain are poorly sorted with high matrix contents. The physical properties decrease continually due to the principally strong compaction and weak dissolution. The present properties of braided channel reservoirs are extremely poor, which is evidenced by few oil layers developed in relatively shallow strata while dry layers entirely in deep. The reservoirs both in the underwater distributary channels and mouth bars are well sorted and have a strong ability to resist compaction. Abundant pores are developed in medium-deep strata because of modifications by two-stage of acidic dissolution and hydrocarbon filling. The

  7. Learning numerical progressions.

    1974-01-01

    Learning of simple numerical progressions and compound progressions formed by combining two or three simple progressions is investigated. In two experiments, time to solution was greater for compound vs simple progressions; greater the higher the progression's solution level; and greater if the progression consisted of large vs small numbers. A set of strategies is proposed to account for progression learning based on the assumption S computes differences between integers, differences between differences, etc., in a hierarchical fashion. Two measures of progression difficulty, each a summary of the strategies, are proposed; C1 is a count of the number of differences needed to solve a progression; C2 is the same count with higher level differences given more weight. The measures accurately predict in both experiments the mean time to solve 16 different progressions with C2 being somewhat superior. The measures also predict the learning difficulty of 10 other progressions reported by Bjork (1968).

    The northern South Carolina coast is a heavily developed region that supports a thriving tourism industry, large local populations and extensive infrastructure (Figure 1). The economic stability of the region is closely tied to the health of its beaches: primarily in providing support for local tourism and protection from storm events. Despite relatively low long-term shoreline erosion rates, and the implied stability of the beaches, the economic impact of storm events to coastal communities has been costly. For example, Hurricane Hugo made landfall on the central South Carolina coast in 1989. High winds and storm surge inflicted roughly $6 billion in property loss and damages, and Hugo remains the costliest storm event in South Carolina history. Localized erosion, commonly occurring around tidal inlets and erosion "hot spots", has also proved costly. Construction and maintenance of hard structures and beach nourishment, designed to mitigate the effects of erosion, have become annual or multi-annual expenditures. Providing a better understanding of the physical processes controlling coastal erosion and shoreline change will allow for more effective management of coastal resources. In 1999, the U.S. Geological Survey (USGS), in partnership with the South Carolina Sea Grant Consortium (SCSGC), began a study to investigate inner continental shelf and shoreface processes. The objectives of the USGS/SCSGC cooperative program are: 1) to provide a regional synthesis of the shallow geologic framework underlying the shoreface and inner continental shelf, and to define its role in coastal evolution and modern beach behavior; 2) to identify and model the physical processes affecting coastal ocean circulation and sediment transport, and to define their role in shaping the modern shoreline; and 3) to identify sediment sources and transport pathways in order to develop a regional sediment budget. This report contains the geospatial data used to define the geologic framework offshore of the northern South Carolina coast. The digital data presented herein accompany USGS Open-File Reports OFR 2004-1013 and OFR 2005-1345, describing the stratigraphic framework and modern sediment distribution within Long Bay, respectively.

    This study analysed the concentrations and toxic-equivalent (TEQ) levels of dioxin congeners in mackerel commercially available in Japan in early 2000s. The content of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like coplanar polychlorinated biphenyls (DL-PCBs) was determined in 17 mackerel samples from different areas. TEQ levels in mackerel muscle were 0.78 pg TEQ g(-)(1) wet weight (wt) on average (range = 0.21-2.26 pg TEQ g(-)(1) wet wt) for PCDD/Fs (PCDDs plus PCDFs), 2.81 pg TEQ g(-)(1) wet wt on average (range = 1.02-8.5 pg TEQ g(-)(1) wet wt) for DL-PCBs, and 3.59 pg TEQ g(-)(1) wet wt on average (range = 1.24-10.8 pg g(-)(1) wet wt) for dioxins (PCDD/Fs plus DL-PCBs). The results revealed somewhat higher TEQ levels for dioxins compared with the other data for fish and shellfish in the Japanese market. TEQ levels were well correlated with mackerel body weight; the main contributors were tetra- and penta-CDD/Fs, some hexa-CDD/Fs, and all 12 DL-PCBs, which are known to have high bioaccumulation potential. In particular, PCB 126 was mostly responsible for the observed correlation of DL-PCB and dioxins-TEQ levels with mackerel body weight. The average daily intake of dioxins in terms of TEQ through mackerel consumption was estimated to be 4.81 pg TEQ/person/day, accounting for 7% of the total intake of dioxins-TEQ through fish and shellfish in Japan.

El estudio destaca la relevancia de la fragilidad del liderazgo presidencial centralizado en democracias de débil institucionalidad como variable explicativa de las caídas presidenciales en América Latina y, específicamente, en Argentina.ABSTRACT: This article explores presidential instability from the point of view of president’s instability –while the classical literature focuses on the instability of presidentialism in itself. The analysis is built on the combination of low democratic institutionalization and weakness of the president’s leadership, which would give an incentive to enforcing an opposition that has influence on the president’s fall. The article stresses the importance of presidential leadership’s fragility in low-institutionalization democracies as a variable that can explain presidential falls in Latin America– and specifically in Argentina.

    Purpose - Healthcare providers differ in their readiness and maturity levels regarding quality and quality management systems applications. The purpose of this paper is to serve as a useful quantitative quality maturity-level assessment tool for healthcare organizations. Design/methodology/approach - The model proposes five quality maturity levels (chaotic, primitive, structured, mature and proficient) based on six quality drivers: top management, people, operations, culture, quality focus and accreditation. Findings - Healthcare managers can apply the model to identify the status quo, quality shortcomings and evaluating ongoing progress. Practical implications - The model has been incorporated in an interactive Excel worksheet that visually displays the quality maturity-level risk meter. The tool has been applied successfully to local hospitals. Originality/value - The proposed six quality driver scales appear to measure healthcare provider maturity levels on a single quality meter.

    Full Text Available Pharmaceutical products are patient-oriented. If they had a deficient quality they might put live at risk. Ensuring their quality is not, however, a straightforward task and this is why different approaches have been used along the way. This article analyzes them and shows how our present approach, if well implemented, is very effective in ensuring quality.Methods. This article analyzes the current pharmaceutical quality system as described by international guidances in the light of practical experience gathered by the author as an international GMP-consultant.Result. Nowadays we have come to understand that as quality is a global concept in terms of time and of requirements, it has to be assured in a global way too. This is why quality assurance is a permanent process that starts during the development of a product and goes on during its manufacturing life. Manufacturing should be performed within a pharmaceutical quality system which ensures GMP compliance. Decisions should be science and risk-based. Products and processes are monitored by means of critical variables.Conclusions. The approach followed in the 21st century for ensuring quality is very effective and allows for a progressive reduction of the level of quality risk. However, this quality system is either comprehensive or there is no quality

    Chronic kidney disease (CKD) patients and their clinicians seek ways to mitigate the risk of CKD progression and its associated complications. Emerging data suggest that dietary modifications may be beneficial adjuvant approaches to reducing the risk of adverse CKD outcomes. This review focuses on several different dietary patterns, including the Dietary Approaches to Stop Hypertension and Mediterranean diets, and their kidney health benefits. We discuss how healthful dietary patterns are lower in dietary acid load and how improving diet quality may slow the progression of CKD. We also discuss some barriers that may impede socially disadvantaged individuals from following healthful diets. Dietary patterns low in dietary acid load might slow the progression of CKD. Current evidence suggests that a reduction in dietary acid load could be beneficial in patients with CKD, but the supremacy of any particular diet is yet to be established. Additional randomized controlled dietary interventions among CKD patients are needed to inform evidence-based recommendations, which can be tailored to an individual's preferences and ability to access healthful foods. © 2016 S.

    Different rates of progression have been observed among patients with Alzheimer disease. Risk factors that accelerate deterioration have been identified and some are being discussed, such as genetics, comorbidity, and the early appearance of Alzheimer disease motor signs. Progressive forms of Alzheimer disease have been reported with rapid cognitive decline and disease duration of only a few years. This short review aims to provide an overview of the current knowledge of rapidly progressive Alzheimer disease. Furthermore, we suggest that rapid, in this context, should be defined as a Mini-Mental State Examination score decrease of 6 points per year.

    生物质水分含量高、能量密度低、储存运输成本高等缺点制约着其转化利用。预处理技术是提高生物质热解产物品质的有效方法之一。为了研究高效经济的预处理技术,本文总结了国内外生物质预处理技术的研究,对干燥法、稀酸法、水热法、烘焙法和生物法等预处理技术进行了重点分析,发现干燥法和烘焙法等技术极具潜力,但是目前的研究仍存在不足,今后还需研究成本低、产率高、污染小的预处理技术,并对预处理技术的发展提出了建议。%Biomass are known for its disadvantages,including high water content,low energy density, difficulty in comminuting into small particles and expensive transportation. However,pretreatment is one of the most effective ways to improve the quality of biomass pyrolysis products. The purpose of biomass pretreatment is to optimize certain features of biomass,such as hardness,particle size, density,composition,and chemical properties,to obtain more and higher quality of bio-oil in its pyrolysis liquefaction process. To improve the pretreatment technology with higher economic efficiency,the study onbiomass pretreatment technologies are reviewed in this paper. Many methods for high quality bio-oil have been discussed. In this review,the pretreatment technology,such as drying methods,acid hydrolysis,torrefaction,hydrothermal and biological methods,are analyzed in focus. Among them,drying methods and torrefaction have the potential in comparison. But the current study are still insufficient,we need to seek new pretreatment technology with lower cost,higher yield and less pollution. Suggestions on the development of pretreatment technology are also included. At present,the single biomass pretreatment methods have their defects,the combination of different pretreatment methods is the important direction in future research , in which the structural characteristics and composition of raw material

    2013-01-01

    Full Text Available Progressive hemifacial atrophy, also known as Parry-Romberg Syndrome, is an uncommon degenerative and poorly understood condition. It is characterized by a slow and progressive but self-limited atrophy affecting one side of the face. The incidence and the cause of this alteration are unknown. A cerebral disturbance of fat metabolism has been proposed as a primary cause. Possible factors that are involved in the pathogenesis include trauma, viral infections, heredity, endocrine disturbances and auto-immunity. The most common complications that appear in association to this disorder are: trigeminal neuralgia, facial paresthesia, severe headache and epilepsy. Characteristically, the atrophy progresses slowly for several years and, it becomes stable. The objective of this work is, through the presentation of a clinical case, to accomplish a literature review concerning general characteristics, etiology, physiopathology and treatment of progressive hemifacial atrophy.

    2006-01-01

    Worldwide primary energy consumption is entering an era of pluralism and high quality under the influence of rapid economic development, increasing energy shortage and strict environmental policies. Although renewable energy technology is developing rapidly, fossil fuels (coal, oil and gas) are still the dominant energy sources in the world. As a country rich in coal but short ofoil and gas, China's oil imports have soared in the past few years. Government, research organizations and enterprises in China are paying more and more attention to the processes of converting coal into clean liquid fuels. Direct and indirect coal liquefaction technologies are compared in this paper based on China's current energy status and technological progress not only in China itself but also in the world.

  11. IDEOLOGY AND PROGRESS

    Directory of Open Access Journals (Sweden)

    Bogdan Constantin Mihăilescu

    2013-02-01

    Full Text Available The progress theme is very important for the ideologies of the Enlightenment political modernity. Moreover, it had received, with the help of the Enlightenment historicism and rationalism, a mythological dimension. Having in view the historical experience that we have today, it is necessary to give up on progress in thismillenarist meaning. But we are observing – as it also results from the political programs presented in the article – that some of the parties affiliated to the forementioned ideologies are approaching in an inconsistent manner the entire theme of the progress. The recession of this theme is part of a larger cultural context, specific for late modernity, when the ideologies seem to be exhausted. But ideologies survive and this fact certifies their power. They continue to impose different reference criteria on politics, and one of the most significant must remainthe progress. But there is also a more modest way to understand progress. Exactly this kind of approach is presented in this article, an approach which is best understood and commented by the help of Richard Rorty's works. Without having the progress as a desideratum, the negative use of power becomes easier. At the same time, the comparative evaluation of the economic, social or political initiatives,and also the social imperatives as solidarity, social cohesion, or the diminishing of the sufferings become more difficult to realize and pursue.

    Progressive visual agnosia was discovered in the 20th century following the discovery of classical non-progressive visual agnosia. In contrast to the classical type, which is caused by cerebral vascular disease or traumatic injury, progressive visual agnosia is a symptom of neurological degeneration. The condition of progressive visual loss, including visual agnosia, and posterior cerebral atrophy was named posterior cortical atrophy (PCA) by Benson et al. (1988). Progressive visual agnosia is also observed in semantic dementia (SD) and other degenerative diseases, but there is a difference in the subtype of visual agnosia associated with these diseases. Lissauer (1890) classified visual agnosia into apperceptive and associative types, and it in most cases, PCA is associated with the apperceptive type. However, SD patients exhibit symptoms of associative visual agnosia before changing to those of semantic memory disorder. Insights into progressive visual agnosia have helped us understand the visual system and discover how we "perceive" the outer world neuronally, with regard to consciousness. Although PCA is a type of atypical dementia, its diagnosis is important to enable patients to live better lives with appropriate functional support.

    Savit, R.

    1993-12-31

    The research centered on the physics of growth. One particular focus was the spiral patterns seen in excitable media, such as the chemical reaction of Belousov and Zhabatinskii, and the aggregation of the slime mold, Dictyostelium Discoideum. Another area of interest is the statistical roughness of the growth front itself. For example, when growing thin films, the roughness of the surface is very important for the ultimate quality of the film. Besides its direct technological relevance, this problem is intimately connected to many fundamental problems in statistical physics. In addition work was done in the related area of statistical properties of flux-flow motion in superconductors. Substantial progress was also made on techniques and applications of the analysis of complex systems. Methods of time series analysis were generalized to the analysis of complex spatio-temporal patterns. In the examples studied most, turbulence and electroencephalograms, the spatio-temporal patterns are very complex and fleeting, and can easily be misken for random noise. Nevertheless, substantial progress was made in developing and applying methods to these systems that indicate the presence of nonrandom time-varying spatial patterns.

  18. Progressive multiple sequence alignments from triplets

    Directory of Open Access Journals (Sweden)

    Stadler Peter F

    2007-07-01

    Full Text Available Abstract Background The quality of progressive sequence alignments strongly depends on the accuracy of the individual pairwise alignment steps since gaps that are introduced at one step cannot be removed at later aggregation steps. Adjacent insertions and deletions necessarily appear in arbitrary order in pairwise alignments and hence form an unavoidable source of errors. Research Here we present a modified variant of progressive sequence alignments that addresses both issues. Instead of pairwise alignments we use exact dynamic programming to align sequence or profile triples. This avoids a large fractions of the ambiguities arising in pairwise alignments. In the subsequent aggregation steps we follow the logic of the Neighbor-Net algorithm, which constructs a phylogenetic network by step-wisely replacing triples by pairs instead of combining pairs to singletons. To this end the three-way alignments are subdivided into two partial alignments, at which stage all-gap columns are naturally removed. This alleviates the "once a gap, always a gap" problem of progressive alignment procedures. Conclusion The three-way Neighbor-Net based alignment program aln3nn is shown to compare favorably on both protein sequences and nucleic acids sequences to other progressive alignment tools. In the latter case one easily can include scoring terms that consider secondary structure features. Overall, the quality of resulting alignments in general exceeds that of clustalw or other multiple alignments tools even though our software does not included heuristics for context dependent (mismatch scores.

  19. Multithreshold progressive image sharing with compact shadows

    Science.gov (United States)

    Chen, Lee Shu-Teng; Lin, Ja-Chen

    2010-01-01

    We propose a multithreshold progressive reconstruction method. The image is encoded three times using Joint Photographic Experts Group (JPEG): first with a low-quality factor, then with a medium-quality factor, and last with a high-quality factor. Huffman coding is employed to encode the difference between the important image and the high-quality JPEG decompressed image. The three JPEG codes and the Huffman code are shared, respectively, according to four prespecified thresholds. The n-generated equally important shadows can be stored or transmitted using n channels in parallel. Cooperation among these generated shadows can progressively reconstruct the important image. The reconstructed image is loss-free when the number of collected shadows reaches the largest threshold. Each shadow is very compact and so can be hidden successfully in the JPEG codes of cover images to reduce the probability of being attacked when transmitted in an unfriendly environment. Comparisons with other image sharing methods are made. The contributions, such as easiness to apply to scalable Moving Picture Experts Group (MPEG) video transmission or resistance to differential attack, are also included.

    Full Text Available I Danmark har vi traditionelt tænkt universiteternes femårige kandidatuddannelser som sammenhængende forløb, hvor den studerende gradvist opbygger en stadig mere specialiseret viden inden for et givet fagområde. Denne idé om progression er i de senere år blevet udfordret fra flere sider. Især er progressionsidéen blevet diskuteret i forhold til tværfaglige uddannelsesforløb, men også de mange internationale uddannelser, der etableres, udfordrer den måde, hvorpå vi traditionelt har forstået progression i det danske uddannelsessystem. På internationale kandidatuddannelser finder vi nemlig typisk både studerende, for hvem kandidatuddannelsen er en forlængelse af en grunduddannelse, og studerende, der har taget deres grunduddannelse et andet sted og muligvis endda i et andet fag. I denne artikel undersøger vi, hvordan undervisere på kandidatuddannelser som både er tværfaglige og internationale forholder sig til progression. Artiklen er skrevet på baggrund af semistrukturerede interviews med undervisere fra tværfaglige, internationale uddannelser ved Aarhus Universitet.University programs in Denmark have traditionally been perceived as a continuous education consisting of three years of basic education followed by two years of specialization within the same discipline. This idea is now being challenged on several fronts. For instance, it is becoming more common for Danish universities to offer interdisciplinary master programs. Also, the trend for greater internationalization in higher education means that programs can attract students from outside Denmark, and these students often come from different academic backgrounds. To investigate how these changes are affecting the way professors who teach on interdisciplinary international masters programs conceive student progress, we carried out semi-structured interviews with teachers on international programs at Aarhus University, the second largest university in Denmark.

  9. Progressive posterior cortical dysfunction

    Directory of Open Access Journals (Sweden)

    Fábio Henrique de Gobbi Porto

    Full Text Available Abstract Progressive posterior cortical dysfunction (PPCD is an insidious syndrome characterized by prominent disorders of higher visual processing. It affects both dorsal (occipito-parietal and ventral (occipito-temporal pathways, disturbing visuospatial processing and visual recognition, respectively. We report a case of a 67-year-old woman presenting with progressive impairment of visual functions. Neurologic examination showed agraphia, alexia, hemispatial neglect (left side visual extinction, complete Balint's syndrome and visual agnosia. Magnetic resonance imaging showed circumscribed atrophy involving the bilateral parieto-occipital regions, slightly more predominant to the right . Our aim was to describe a case of this syndrome, to present a video showing the main abnormalities, and to discuss this unusual presentation of dementia. We believe this article can contribute by improving the recognition of PPCD.

    Full Text Available Determining radiographic progression in primary malignant brain tumors has posed a significant challenge to the neuroncology community. Glioblastoma multiforme (GBM, WHO Grade IV through its inherent heterogeneous enhancement, growth patterns, and irregular nature has been difficult to assess for progression. Our ability to detect tumor progression radiographically remains inadequate. Despite the advanced imaging techniques, detecting tumor progression continues to be a clinical challenge. Here we review the different criteria used to detect tumor progression, and highlight the inherent challenges with detection of progression.

    In recent years, many foreign and domestic scholars have made a further study on the risk factors, high-risk groups, prevention and nursing of pressure ulcers. For all reasons such as clinical nursing workers and managers, new progresses can' t be well applied, and simultaneously pressure ulcers are misunderstood to some extent. These conditions are not conducive to the prevention and nursing of pressure ulcers and the improvement of patients' life quality and nursing service quality. Therefore, it is necessary to keep away from the misunderstanding, know well new progresses and reduce the incidence of pressure ulcers.

Is there a core of elements that form a general definition of architectural quality? 2) Prefab...... dwellings often seem to be looked upon as a lower class of dwellings - should it not be possible to build prefab dwellings of high architectural quality? 3) Wood is increasingly often seen in contemporary Danish building and is used as a cheap, strong, light and environmentally friendly material, but what...... quality of prefab wooden dwellings. This is done through a state of the art on architectural quality and a structuring of the presented theories into three theoretical clusters that are defined through three keywords each.

  3. Understanding Progress: A Heterodox Approach

    Directory of Open Access Journals (Sweden)

    Blanca Lemus

    2013-01-01

    Full Text Available This paper examines the possibility of understanding and measuring well-being as a result of “progress” on the basis of today’s dominant epistemological framework. Market criteria distort social values by allowing purchasing power to define priorities, likening luxury goods to basic needs; in the process they reinforce patterns of discrimination against disadvantaged social groups and women, introducing fatal distortions into the analysis. Similarly, because there are no appropriate mechanisms to price natural resources adequately, the market overlooks the consequences of the abuse of natural resources, degrading the quality of life, individually and collectively, or—in the framework of Latin American indigenous groups—foreclosing the possibility of “living well”. We critique the common vision of the official development discourse that places its faith on technological innovations to resolve these problems. The analysis points to the need for new models of social and environmental governance to promote progress, approaches like those suggested in the paper that are inconsistent with public policies currently in place. At present, the social groups forging institutions to assure their own well-being and ecological balance are involved in local processes, often in opposition to the proposals of the political leaders in their countries.

    A new family of exact solutions to the wave equation representing relatively undistorted progressive waves is constructed using separation of variables in the elliptic cylindrical coordinates and one of the Bateman transforms. The general form of this Bateman transform in an orthogonal eurvilinear cylindrical coordinate system is discussed and a specific problem of physical feasibility of the obtained solutions, connected with their dependence on the cyclic coordinate, is addressed. The limiting case of zero eccentricity, in which the elliptic cylindrical coordinates turn into their circular cylindrical counterparts, is shown to correspond to the focused wave modes of the Bessel-Gauss type.

    2016-06-01

    Full Text Available Research Question: The existence of organizations in competitive markets depends on their ability to stay competitive. Quality departments play a key role in organizing and ensuring quality. Purpose: The survey tries to determine the correlation between the existence of quality departments and organization of quality in organizations; our hypothesis is that the correlation is very strong. Method: A survey was performed in 484 large and medium-sized organizations in Slovenia to examine the situation in this area. Pearson's χ2-test was used for data processing and results presented in a contingency table. Results: Organizations with quality departments more frequently also have certificate ISO 9001 in comparison with organizations without quality departments. Also these organizations more frequently have supplier-relations teams, monitoring system of suppliers' progress and excellence centers. In short, the quality in these organizations is organized on a higher level than in organizations without quality departments. Organization: The role of quality department is important for organizations. The findings of the research are important for decision making in organizations. Society: Each organization contributes to efficiency and effectiveness of a nation. The organizational level of the nation can be measured by number of certificates per capita. Originality: The research is unique because of the research model and method applied. Limitations/Future Research: The research is limited to large and medium-sized organizations in Slovenia.

    ointment. Several studies have shown that lower concentrations of atropine slow the progression of myopia control with fewer side effects than 1% atropine. While the progression of myopic refractive error is slowed with lower concentration of atropine, the growth of the eye is not, indicating a potentially reversible form of myopia control that may diminish after discontinuation of the eye drops. This review provides an overview of the myopia control information available in the literature and raises questions that remain unanswered, so that eye care practitioners and parents can potentially learn the methods that may ultimately improve a child’s quality of life or lower the risk of sight-threatening complications.Keywords: myopia control, children, review, atropine, orthokeratology, soft bifocal contact lenses

    The Network Control Center (NCC) Project introduced the concept of total quality management (TQM) in mid-1990. The CSC project team established a program which focused on continuous process improvement in software development methodology and consistent deliveries of high quality software products for the NCC. The vision of the TQM program was to produce error free software. Specific goals were established to allow continuing assessment of the progress toward meeting the overall quality objectives. The total quality environment, now a part of the NCC Project culture, has become the foundation for continuous process improvement and has resulted in the consistent delivery of quality software products over the last three years.

    Full Text Available Effectiveness of quality management in the effort to satisfy customers' expectations has been questioned both by academicians and practitioners. In the course of the evolution of quality, very important theories have been developed in the field but failed to satisfy customers' expectation. The aim of this paper is to examine the challenge and develop a new method to address it. Following a literature review on the evolution of the concept of quality, confusions and limitations in the present paradigm are clarified. Then the future quality paradigm is proposed, and two practical cases are presented to substantiate the new approach. Quality management evolved from product inspection at the final stages of the production process. Basically, manufacturers take care of quality up to the point where a product is delivered to a customer. Product failure occurs due to various reasons after purchase. However, this happened or discovered during operational phase of the product which subsequently result in dissatisfaction for the users after purchase. To address this misalignment, all inclusive approach called Lifecycle Quality came into being as the future generation's paradigm. Misalignment between the manufacturer and the customer's desire in the operational phases of a product life - time leads to market loss to the former and dissatisfaction to the latter. Considering lifecycle quality of the product will definitely resolve the occurrence of such undesired outcomes affecting the two parties.

    Genome-wide expression studies transformed the field of transcriptomics and made it feasible to study global gene expression in extraordinary detail. These new methods have revealed an enhanced view of the transcriptional landscape and have yielded many biological insights. It is increasingly clear that the prokaryotic transcriptome is much more complex than once thought. Recent advances in microbial transcriptome analyses are highlighted in this review. Areas of progress include the development of optimized techniques that minimize the abundance of ribosomal RNAs in RNA samples as well as the development of novel methods to create transcriptome libraries. Advances such as these have led to a new emphasis in areas such as metatranscriptomics and single cell gene expression studies. Published by Elsevier Ltd.

    Progressive band selection (PBS) reduces spectral redundancy without significant loss of information, thereby reducing hyperspectral image data volume and processing time. Used onboard a spacecraft, it can also reduce image downlink time. PBS prioritizes an image's spectral bands according to priority scores that measure their significance to a specific application. Then it uses one of three methods to select an appropriate number of the most useful bands. Key challenges for PBS include selecting an appropriate criterion to generate band priority scores, and determining how many bands should be retained in the reduced image. The image's Virtual Dimensionality (VD), once computed, is a reasonable estimate of the latter. We describe the major design details of PBS and test PBS in a land classification experiment.

    The electronic health record (EHR) has been viewed with both praise and skepticism. Multiple editorials have expressed concerns that EHR implementation and "efficiency tools" such as copy forward and auto population have resulted in a decrement in note accuracy, relevance, and critical thinking. To evaluate the perceptions of internal medicine housestaff and attendings on inpatient progress note quality at 4 academic institutions after the implementation of an EHR. Cross-sectional survey. We developed surveys that assessed housestaff and attendings opinion of current progress note quality, the impact of the EHR on quality, and the purposes of a progress note. We received 99 completed surveys from interns (66%), 155 from residents (49%), and 153 from attendings (70%) across 4 institutions. The majority of housestaff responded that the quality of notes was "unchanged" or "better" following the implementation of an EHR, whereas attendings believed note quality was "unchanged" or "worse." Attendings' perceptions of housestaff notes were significantly lower than housestaff perceptions of their own notes across all domains. With regard to the effect of copy forward and autopopulation, the majority of housestaff viewed these to be "neutral" or "somewhat positive," whereas attendings viewed these as "neutral" or "somewhat negative." Housestaff and attendings had nearly perfect agreement regarding the purpose of the progress note. Attendings and housestaff disagree on the current quality of progress notes and the impact of an EHR on note quality, but agree on the purpose of a progress note. © 2015 Society of Hospital Medicine.

    This community initiative called Clean Air Hamilton was established to improve air quality in Hamilton, Ontario. It has been mandated to annually report on progress and provide advice with regard to current air quality issues. The quality of life of residents is improved as a result of the work performed by Clean Air Hamilton, and it also enhances Hamilton's image. Numerous inquiries have been received from City officials in several municipalities such as Toronto, Kitchener-Waterloo and Windsor as a testament to the success of the initiative. Financial support is received from all levels of government. The funding received from the Council has helped in attracting additional donations in support of this initiative. Clean Air Hamilton was involved in one capacity or another in research, emissions reduction projects and public awareness campaigns during 2001, and its contributions were valued at approximately 500,000 dollars. The City of Hamilton was awarded the United Nations for Human Settlements award as a result of Clean Air Hamilton's community process in local air quality improvement. In addition, the City received the Dubai International Award for Best Practices in Improving the Living Environment. Clean Air Hamilton is ready to move to the next phase, which requires moving current structures that supplements voluntary commitments with committed funding from key stakeholders. Since June 1996, the advisory level of 32 on the Air Pollution Index has not been reached, and rarely goes over 20. Throughout the 1990s, levels of toxics have decreased significantly. A three-year self-sustaining program should be developed and funding sought for those initiatives, discussions should be facilitated among industrial stakeholders when they address air quality issues, and research should continue to be supported and advice on current air quality issues be provided to City Council. 1 fig.

  2. Progressive familial intrahepatic cholestasis

    2009-01-01

    Full Text Available Abstract Progressive familial intrahepatic cholestasis (PFIC refers to heterogeneous group of autosomal recessive disorders of childhood that disrupt bile formation and present with cholestasis of hepatocellular origin. The exact prevalence remains unknown, but the estimated incidence varies between 1/50,000 and 1/100,000 births. Three types of PFIC have been identified and related to mutations in hepatocellular transport system genes involved in bile formation. PFIC1 and PFIC2 usually appear in the first months of life, whereas onset of PFIC3 may also occur later in infancy, in childhood or even during young adulthood. Main clinical manifestations include cholestasis, pruritus and jaundice. PFIC patients usually develop fibrosis and end-stage liver disease before adulthood. Serum gamma-glutamyltransferase (GGT activity is normal in PFIC1 and PFIC2 patients, but is elevated in PFIC3 patients. Both PFIC1 and PFIC2 are caused by impaired bile salt secretion due respectively to defects in ATP8B1 encoding the FIC1 protein, and in ABCB11 encoding the bile salt export pump protein (BSEP. Defects in ABCB4, encoding the multi-drug resistant 3 protein (MDR3, impair biliary phospholipid secretion resulting in PFIC3. Diagnosis is based on clinical manifestations, liver ultrasonography, cholangiography and liver histology, as well as on specific tests for excluding other causes of childhood cholestasis. MDR3 and BSEP liver immunostaining, and analysis of biliary lipid composition should help to select PFIC candidates in whom genotyping could be proposed to confirm the diagnosis. Antenatal diagnosis can be proposed for affected families in which a mutation has been identified. Ursodeoxycholic acid (UDCA therapy should be initiated in all patients to prevent liver damage. In some PFIC1 or PFIC2 patients, biliary diversion can also relieve pruritus and slow disease progression. However, most PFIC patients are ultimately candidates for liver transplantation

  3. Dynamically prioritized progressive transmission

    Science.gov (United States)

    Blanford, Ronald

    1992-04-01

    Retrieval of image data from a centralized database may be subject to bandwidth limitations, whether due to a low-bandwidth communications link or to contention from simultaneous accesses over a high-bandwidth link. Progressive transmission can alleviate this problem by encoding image data so that any prefix of the data stream approximates the complete image at a coarse level of resolution. The longer the prefix, the finer the resolution. In many cases, as little at 1 percent of the image data may be sufficient to decide whether to discard the image, to permit the retrieval to continue, or to restrict retrieval to a subsection of the image. Our approach treats resolution not as a fixed attribute of the image, but rather as a resource which may be allocated to portions of the image at the direction of a user-specified priority function. The default priority function minimizes error by allocating more resolution to regions of high variance. The user may also point to regions of interest requesting priority transmission. More advanced target recognition strategies may be incorporated at the user's discretion. Multispectral imagery is supported. The user engineering implications are profounded. There is immediate response to a query that might otherwise take minutes to complete. The data is transmitted in small increments so that no single user dominates the communications bandwidth. The user-directed improvement means that bandwidth is focused on interesting information. The user may continue working with the first coarse approximations while further image data is still arriving. The algorithm has been implemented in C on Sun, Silicon Graphics, and NeXT workstations, and in Lisp on a Symbolics. Transmission speeds reach as high as 60,000 baud using a Sparc or 68040 processor when storing data to memory; somewhat less if also updating a graphical display. The memory requirements are roughly five bytes per image pixel. Both computational and memory costs may be reduced

    Photovoltaics for Utility Scale Applications (PVUSA) is a national public-private partnership that is assessing and demonstrating the viability of utility-scale photovoltaic (PV) electric generating systems. PVUSA participants include Pacific Gas & Electric (PG&E), the US Department of Energy (DOE), the Electric Power Research Institute (EPRI), the California Energy Commission (CEC), and eight utilities and other agencies. This report updates the progress of the PVUSA project, reviews the status and performance of the various PV installations during 1991, and summarizes key findings and conclusions from work to date. PVUSA offers utilities hands-on experience needed to evaluate and utilize maturing PV technology. The project also provides manufacturers a test bed for their products, encourages technology improvement and cost reductions in PV modules and other system components, and establishes communication channels between utilities and the PV industry. The project consists of two types of demonstrations: Emerging Module Technology (EMT) arrays, which are unproven but promising state-of-the-art PV technologies in 20-kW (nominal) arrays; and Utility Scale (US) systems, which represent more mature PV technologies in 200- to 500-kW turnkey systems.

    Photovoltaics for Utility Scale Applications (PVUSA) is a national public-private partnership that is assessing and demonstrating the viability of utility-scale photovoltaic (PV) electric generation systems and recent developments in module technology. This report updates the progress of the PVUSA project, review the status and performance of all PV installations during 1993, and summarizes key accomplishments and conclusions for the year. The PVUSA project has five objectives designed to narrow the gap between a large utility industry that is unfamiliar with PV, and a small PV industry that is aware of a potentially large utility market but unfamiliar with how to meet its requirements. The objectives are: to evaluate the performance, reliability, and cost of promising PV modules and balance-of-system (BOS) components side-by-side at a single location; to assess PV system operation and maintenance (O and M) in a utility setting; to compare PV technologies in diverse geographic areas; to provide US utilities with hands-on experience in designing, procuring, and operating PV systems; and to document and disseminate knowledge gained from the project.

  9. IPY Progress and Prospects

    We can summarize the IPY goals as: (a) make major advances in polar knowledge and understanding; (b) leave a legacy of new or enhanced observational systems, facilities and infrastructure; (c) excite a new generation of polar scientists and engineers, and (d) elicit exceptional interest and participation from polar residents, schoolchildren, the general public, and decision-makers, worldwide. This talk reports on the progress and prospects in each of those areas from an overall international view; separate talks will describe details of future researcher and the IPY outreach efforts. To achieve major advances in knowledge, IPY has entrained the intellectual resources of thousands of scientists, many more than expected, often from 'non- polar' nations, and representing an unprecedented breadth of scientific specialties; integration of those efforts across disciplines to achieve integrated system-level understanding remains a substantial challenge. Many national and international organizations prepare plans to sustain new and improved observational systems, but clear outcomes and the necessary resources remain elusive. International outreach networks gradually build breadth and strength, largely through IPY Polar Science Days and other internationally- coordinated IPY events. A new Association of Polar Early Career Scientists (APECS) devotes talent and energy to shaping the future of polar research. These activities and networks may, with time and with continued international coordination, achieve an exceptional level of interest and participation. In all areas, much work remains.

    1997-12-31

    1997 was another year of intense activity for the ENEA Nuclear Fusion Division in the evolving scenario of fusion research. With respect to the International Thermonuclear Experimental Reactor (ITER), a major review process has started, originate by the wide perception that the difficult financial situation affecting some of the parties would make it very difficult, practically impossible, to secure funding for the project as it stands. To scale down the size and cost of the machine by reducing the technical objectives, while keeping to the programmatic goal of constructing a demonstration reactor (DEMO) as the following step, appears achievable. Progress in physics was substantial during 1997. Analysis of the huge existing database, complemented by the latest results, had led to a better, more accurate scaling for the confinement time on which to base extrapolation to ITER. Studies of the very promising advanced regimes have been pursued on many tokamaks. The Frascati Tokamak Upgrade (FTU) is well placed in this respect since it is equipped with the right tools, lower hybrid and electron cyclotron radiofrequency heating and current drive systems, to explore the new promised land of low transport from the plasma core. The main highlights of FTU operation in 1997 were related to providing information relevant to these future developments. Transient production of low transport regimes with electron temperatures of 8-9 keV at the plasma center was obtained by taking advantage of the plasma skin effect and precise electron cyclotron power deposition. High-efficiency current drive at high density using lower hybrid waves was demonstrated. High-confinement pellet-enhanced modes of operation and good ion Bernstein wave coupling through the waveguide-type coupler were also achieved. Concerning the IGNITOR experiment, funds were made available only for continuation of the engineering design activities, and nothing has been released so far for manufacturing the additional

    LIFE-II inertial confinement fusion power plant design study uses a liquid fall, in the form of jets to protect the first structural wall from neutron damage, x rays, and blast to provide a 30-y lifetime. This is a progress report of an incomplete and ongoing study. HYLIFE-I used liquid lithium. HYLIFE-11 avoids the fire hazard of lithium by using a molten salt composed of fluorine, lithium, and beryllium (Li{sub 2}Be{sub 4}) called Flibe. Access for heavy-ion beams is provided. Calculations for assumed heavy-ion beam performance show a nominal gain of 70 at 5 MJ producing 350 MJ, about 5.2 times less yield than the 1.8 GJ from a driver energy of 4.5 MJ with gain of 400 for HYLIFE-I. The nominal 1 GWe of power can be maintained by increasing the repetition rate by a factor of about 5.2, from 1.5 to 8 Hz. A higher repetition rate requires faster re-establishment of the jets after a shot, which can be accomplished in part by decreasing the jet fall height and increasing the jet flow velocity. Multiple chambers may be required.In addition, although not considered for HYLIFE-I there is undoubtedly liquid splash that must be forcibly cleared because gravity is too slow, especially at high repetition rates. Splash removal can be accomplished by either pulsed or oscillating jet flows. The cost of electricity is estimated to be 0.10 $/kW{center dot} in constant 1990 dollars, about twice that of future coal and light water reactor nuclear power. The driver beam cost is about one-half the total cost.

    Fusion research is undertaken all over the world with the objective of realising an environmentally responsible source of energy with essentially unlimited and widely distributed fuel reserves. The results of the worldwide efforts made in recent years are now embodied in ITER, the International Thermonuclear Experimental Reactor, designed to produce at least 500 MW of fusion power with a power gain of ten. ITER will test for the first time the interaction of fusion plasma physics with power station technology. In this international framework, during 2004 Fusion Technical and Scientific Unit of ENEA obtained important results in several keys areas. At the Frascati Tokamak Upgrade the lower hybrid microwave system was fully exploited to study the generation and control of the plasma current, and the electron cyclotron heating system reached full power (1.5 MW). With the simultaneous injection of the two waves, good energy confinement regimes with internal transport barriers were obtained at the highest plasma densities ever achieved. Advanced scenario regimes were also addressed in the activities of ENEA at JET. The engineering design of the IGNITOR machine was finalised, and significant progress was made in understanding the plasma physics regimes. Among the technology activities, the qualification of the deposition process of a copper liner on carbon fibre composite (CFC) hollow tiles may be mentioned as the most important achievement. This innovative pre brazed casting process is a competitive candidate for the fabrication of the CFCbased ITER divertor components. ENEA participated in the European activity for the definition and production on an industrial scale of an advanced Nb3Sn strand for the ITER superconducting central solenoid and toroidal field coils. Contributions were also made to the design of the final conductor layout and the characterisation tests. Inertial fusion studies continued along the previous lines, namely, the study of the implosion

    2016-04-01

    What is scientific progress? On Alexander Bird's epistemic account of scientific progress, an episode in science is progressive precisely when there is more scientific knowledge at the end of the episode than at the beginning. Using Bird's epistemic account as a foil, this paper develops an alternative understanding-based account on which an episode in science is progressive precisely when scientists grasp how to correctly explain or predict more aspects of the world at the end of the episode than at the beginning. This account is shown to be superior to the epistemic account by examining cases in which knowledge and understanding come apart. In these cases, it is argued that scientific progress matches increases in scientific understanding rather than accumulations of knowledge. In addition, considerations having to do with minimalist idealizations, pragmatic virtues, and epistemic value all favor this understanding-based account over its epistemic counterpart.

    Progress is reported in six areas of research: air quality, water quality, ecosystem quality, subsidence and seismicity, socioeconomic effects, and integrated assessment. A major goal of the air quality element is to evaluate the rate of emission of H/sub 2/S, CO/sub 2/, H/sub 2/, N/sub 2/, CH/sub 4/, and C/sub 2/H/sub 6/ from the operation of the geothermal loop experimental facility at Niland. Concentrations of H/sub 2/S were found to vary between 1500 to 4900 ppM by volume at the Niland facility. To distinguish between geothermal fluids and other waters, extensive sampling networks were established. A major accomplishment was the installation of a high-resolution subsidence-detection network in the Salton Sea geothermal field area, centered on the test facility at Niland. A major effort went into establishing a background of data needed for subsequent impact assessments related to socioeconomic issues raised by geothermal developments. Underway are a set of geothermal energy scenarios that include power development schedules, technology characterizations, and considerations of power-plant-siting criteria. A Gaussian air-pollution model was modified for use in preliminary air-quality assessments. A crop-growth model was developed to evaluate impacts of gases released from geothermal operations on various agricultural crops. Work is also reported on the legal analysis of geothermal legislation and the legal aspects of water-supply utilization. Remote sensing was directed primarily at the Salton Sea, Heber, Brawley, and East Mesa KGRAs. However, large-format photography of the entire Salton Trough was completed. Thermal and multispectral imaging was done for several selected sites in the Salton Sea KGRA. (JGB)

  10. Assessment of subsurface chlorinated solvent contamination using tree cores at the front street site and a former dry cleaning facility at the Riverfront Superfund site, New Haven, Missouri, 1999-2003

    Tree-core sampling has been a reliable and inexpensive tool to quickly assess the presence of shallow (less than about 30 feet deep) tetrachloroethene (PCE) and trichloroethene (TCE) contamination in soils and ground water at the Riverfront Superfund Site. This report presents the results of tree-core sampling that was successfully used to determine the presence and extent of chlorinated solvent contamination at two sites, the Front Street site (operable unit OU1) and the former dry cleaning facility, that are part of the overall Riverfront Superfund Site. Traditional soil and ground-water sampling at these two sites later confirmed the results from the tree-core sampling. Results obtained from the tree-core sampling were used to design and focus subsequent soil and ground-water investigations, resulting in substantial savings in time and site assessment costs. The Front Street site is a small (less than 1-acre) site located on the Missouri River alluvium in downtown New Haven, Missouri, about 500 feet from the south bank of the Missouri River. Tree-core sampling detected the presence of subsurface PCE contamination at the Front Street site and beneath residential property downgradient from the site. Core samples from trees at the site contained PCE concentrations as large as 3,850 mg-h/kg (micrograms in headspace per kilogram of wet core) and TCE concentrations as large as 249 mg-h/kg. Soils at the Front Street site contained PCE concentrations as large as 6,200,000 mg/kg (micrograms per kilogram) and ground-water samples contained PCE concentrations as large as 11,000 mg/L (micrograms per liter). The former dry cleaning facility is located at the base of the upland that forms the south bank of the Missouri River alluvial valley. Tree-core sampling did not indicate the presence of PCE or TCE contamination at the former dry cleaning facility, a finding that was later confirmed by the analyses of soil samples collected from the site. The lateral extent of PCE contamination in trees was in close agreement with the extent of subsurface PCE contamination determined using traditional soil and ground-water sampling methods. Trees growing in soils containing PCE concentrations of 60 to 5,700 mg/kg or larger or overlying ground water containing PCE concentrations from 5 to 11,000 mg/L generally contained detectable concentrations of PCE. The depth to contaminated ground water was about 20 to 25 feet below the land surface. Significant quantitative relations [probability (p) values of less than 0.05 and correlation coefficient (r2) values of 0.88 to 0.90] were found between PCE concentrations in trees and subsurface soils between 4 and 16 feet deep. The relation between PCE concentrations in trees and underlying ground water was less apparent (r2 value of 0.17) and the poor relation is thought to be the result of equilibrium with PCE concentrations in soil and vapor in the unsaturated zone. Based on PCE concentrations detected in trees at the Front Street site and trees growing along contaminated tributaries in other operable units, and from field hydroponic experiments using hybrid poplar cuttings, analysis of tree-core samples appears to be able to detect subsurface PCE contamination in soils at levels of several hundred micrograms per liter or less and PCE concentrations in the range of 8 to 30 mg/L in ground water in direct contact with the roots. Loss of PCE from tree trunks by diffusion resulted in an exponential decrease in PCE concentrations with increasing height above the land surface in most trees. The rate of loss also appeared to be a function of the size and growth characteristics of the tree as some trees exhibited a linear loss with increasing height. Diffusional loss of PCE in small (0.5-inch diameter) trees was observed to occur at a rate more than 10 times larger than in trees 6.5 inches in diameter. Concentrations of PCE also exhibited directional variability around the tree trunks and concentration differe

    Quality of life (QOL) refers to an individual's perception and subjective evaluation of their health and well-being, and has become an important index to evaluate the outcomes of clinical treatment in the last past decades. There are a large number of different instruments to evaluate QOL, and the 36-Item Short Form Health Survey (SF-36) is currently one of the most widely used instruments. In recent years, SF-36 has been used to evaluate QOL of valvular heart disease patients to investigate the risk factors those influence their postoperative QOL, provide more preoperative evaluation tools for clinical physicians, and improve postoperative outcomes of patients with valvular heart disease. However, it is now just the beginning to use SF-36 to examine QOL of valvular heart disease patients. Because of significant differences in sample size, follow-up period, country and culture, current research has some controversial results. This review focuses on the progress in evaluating QOL in postoperative patients with valvular heart disease using SF-36.%生活质量评估是从患者主观感受角度评估患者病情,近半个世纪来,逐渐成为临床评价治疗效果的一项重要指标.生活质量评估量表众多,SF-36健康调查简表(the 36-Item Short Form Health Survey,SF-36)是目前应用最广泛的量表.近年来,SF-36量表逐渐应用于探索影响心脏瓣膜病患者术后生活质量的危险因素,为临床医生提供了更多的术前评估方法,提高了手术治疗效果.但目前SF-36用于评估心脏瓣膜病患者生活质量刚刚起步,受样 ,本量、随访时间、地域、文化等因素的影响,结论有一定分歧.为此,我们对目前用SF-36量表评估心脏瓣膜病患者术后生活质量的研究进展进行综述,以更好地应用SF-36量表.

    Manufacturers continue to upgrade fluidized bed and steam technologies to meet more stringent emission, efficiency and service challenges from global power market customers. Offshore, suppliers are being pushed to provide quality, low-cost production and significant local competitive presence in nearly all international markets. The ability to meet customer and regulatory demands for emissions across different global market segments remains a priority for prime mover suppliers as they develop environmental technical improvements. Products initially developed for the more stringent European regulations are now finding a market in the US. In developing countries, demand continues for utility-size boiler products, but pollution control equipment costs remain a parallel consideration. Industry improvements to steam cycle equipment, namely turbines, continue to reap benefits in terms of efficiency and operational flexibility. Boiler and steam manufacturers` response to global markets remains right on target as product development strategies are constantly adjusted and analyzed to reach an optimum marketing mix. Innovation and advances in prime mover power equipment technology remain a mainstay of suppliers` ability to meet the needs of a changing, competitive clientele.

    The 4.3m SOAR telescope is fully funded and under construction. A partnership between the country of Brazil, NOAO, Michigan State University, and the University of North Carolina at Chapel Hill, SOAR is being designed for high-quality imaging and imaging spectroscopy in the optical and near-IR over a field of view up to 12' diameter. US astronomers outside MSU and UNC will access 30% of the observing time through the standard NOAO TAC process. The telescope is being designed to support remote and synoptic observations. First light is scheduled for July 2002 at Cerro Pachon in Chile, a site with median seeing of 2/3" at 500 nm. The telescope will be operated by CTIO. Corning Inc. has fused the mirror blanks from boules of ULE glass. RSI in Richardson, Texas and Raytheon Optical Systems Inc. in Danbury, Conn. are designing and will fabricate the mount and active optics systems, respectively. The mount supports an instrument payload in excess of 5000 kg, at 2 Nasmyth locations and 3 bent Cass. ports. The mount and facility building have space for a laser to generate an artificial AO guide star. LabVIEW running under the Linux OS on compactPCI hardware has been adopted to control all telescope, detector, and instrument systems. The primary mirror is 10 cm thick and will be mounted on 120 electro-mechanical actuators to maintain its ideal optical figure at all elevations. The position of the light-weighted secondary mirror is adjusted to maintain collimation through use of a Shack-Hartmann wavefront sensor. The tertiary mirror feeds instruments and also jitters at up to 50 Hz to compensate for telescope shake and atmosphere wavefront tilt. The dome is a steel framework, with fiberglass panels. Air in the observing volume will be exchanged with that outside every few minutes by using large fans under computer control. All systems will be assembled and checked at the manufacturer's facility, then shipped to Chile. A short integration period is planned, and limited science

    Metastatic complications are responsible for more than 90% of cancer-related deaths. The progression from an isolated tumor to disseminated metastatic disease is a multistep process, with each step involving intricate cross talk between the cancer cells and their non-cellular surroundings, the extracellular matrix (ECM). Many ECM proteins are significantly deregulated during the progression of cancer, causing both biochemical and biomechanical changes that together promote the metastatic cascade. In this review, the influence of several ECM proteins on these multiple steps of cancer spread is summarized. In addition, we highlight the promising (pre-)clinical data showing benefits of targeting these ECM macromolecules to prevent cancer progression.

    2014-01-01

    Since the publication of the French national survey of violence against women in 2000, the fight against domestic violence has made steady progress. Knowledge of the phenomenon has significantly improved. A nationwide study of murders and manslaughters perpetrated by one partner of a couple against the other has been published annually since 2006. In 2012, domestic violence resulted in the deaths of 314 persons: 166 women, 31 men, 25 children, 9 collateral victims, 14 rivals, and two former spouses killed by their ex-fathers in law. In addition, 67 perpetrators committed suicide (51 men and3 women). The number of victims fluctuates from year to year but has remained fairly stable since 2006 (n=168). Legislation has improved significantly: eight new laws have been passed since 2004, all designed to protect women and to ensure that violent men are restrained and treated. New measures to inform and protect women have been implemented and others have been improved, such as the anonymous helpline (phone no 3919, "domestic violence information"). An inter-ministerial committee on the protection of women from violence and the prevention of human trafficking (MIPROF) was created on 3 January 2013. A website entitled "Stop violence against women " (Stop violences faites aux femmes) is now available. The "Imminent Danger" mobile phone system, designed to alert police if a suspected or known perpetrator breaches restraint conditions, will be extended to the entire country from January 2014. Referees charged with coordinating comprehensive long-tern care of women victims have been deployed at the county level. Information centers on the rights of women and families (CIDFF) now form a local nationwide network. Routine interviews with a midwife during the fourth month of pregnancy, focusing on the woman's emotional, economic and social conditions, have been implemented in 21 % of maternity units and should gradually be generalized. The authorities who have enforced the law have

    This report documents the activities within the CBM project in 2007. Significant progress has been made in the optimization of the simulation software, the layout and development of detectors, the design of front-end electronics, and the concepts for data acquisition. The simulation and analysis routines have been completely integrated into the software framework (FAIRoot and CBMroot), and can be used now easily by users outside GSI. A breakthrough has been achieved in the development of fast algorithms for track and vertex reconstruction which have been improved in speed by a factor of 10{sup 5}. These fast routines permit to perform high-statistics simulations for detailed detector layout optimization. Full event reconstruction based on realistic detector properties and particle multiplicities as given by microscopic transport models are routinely used in the feasibility studies. A version of the Silicon Tracking System is now implemented in the simulation software comprising 8 detector layers based on microstrip technology only, including the readout cables, and the mechanical detector structure. The studies of open charm detection have been extended to D{sub s}{sup +} and {lambda}{sub c}, taking into account a realistic layout of the Silicon Pixel Microvertex detector. The identification of electrons has been optimized by improved ring recognition algorithms and transition radiation simulations. The Ring Imaging Cherenkov (RICH) detector has been redesigned, resulting in a reduction by a factor of two in mirror size and number of readout channels without reducing the pion rejection capability. The muon detection system has been optimized with respect to the number of detector layers. The muon simulations take into account detector inefficiencies and a segmentation of the muon chambers into pads according to a nominal occupancy of 5% for central Au+Au collisions. Studies for a dimuon trigger show promising results. Radiation dose simulations using the FLUKA

    Patients as human beings determined by their structure cannot, while having an experience, distinguish between an illusion and reality, therefore they experience the different domains of existence and the different domains of reality. For them, the perception of service quality is experienced as a personal domain of reality, and this reality is a personal construction, generating as many realities as patients perceiving their experience with elements of their experience, whose distinctions that validate it are not necessarily shared or agreed. Health management must abandon the idea in that it is possible to build an objective quality service, to be able to make progress in building effective communication strategies and common consensus criteria for a quality service of distinction, in order to achieve effective satisfaction and patient loyalty.

    Full Text Available In the last decades, there was a strong national and international tendency to increase the services role in the economic social life. The technical progress, the enhancing social division of labor and the increase of demand both from the population and entrepreneurs led to the services development and diversification. Due to the recent radical changes in all economic, political and social fields, the economic agents’ goal to gain a rapid and substantial profit was gradually replaced by the fierce struggle for quality domination among competitors. Therefore, there is an increasing need to find more effective ways to improve the services quality, such as training and motivating the staff and implementing a quality management system.

    Monomelic amyotrophy is a sporadic juvenile-onset disease that presents with gradual onset of weakness and atrophy in the hand muscles unilaterally. Generally, this disease is considered a 'benign' and non-progressive motor neuron disease, which stabilizes within five years of onset. We discuss a case that illustrates that monomelic amyotrophy may rarely exhibit late clinical progression to the lower extremities after a prolonged period of disease stability.

    Bedington, Robert; Arrazola, Juan Miguel; Ling, Alexander

    2017-08-01

    Quantum key distribution (QKD) is a family of protocols for growing a private encryption key between two parties. Despite much progress, all ground-based QKD approaches have a distance limit due to atmospheric losses or in-fibre attenuation. These limitations make purely ground-based systems impractical for a global distribution network. However, the range of communication may be extended by employing satellites equipped with high-quality optical links. This manuscript summarizes research and development which is beginning to enable QKD with satellites. It includes a discussion of protocols, infrastructure, and the technical challenges involved with implementing such systems, as well as a top level summary of on-going satellite QKD initiatives around the world.

    This progress report details the results and status of Washington Department of Fisheries' (WDF) pre-facility monitoring, research, and evaluation efforts, through May 1991, designed to support the development of an Experimental Design Plan (EDP) for the Yakima/Klickitat Fisheries Project (YKFP), previously termed the Yakima/Klickitat Production Project (YKPP or Y/KPP). This pre- facility work has been guided by planning efforts of various research and quality control teams of the project that are annually captured as revisions to the experimental design and pre-facility work plans. The current objective are as follows: to develop genetic monitoring and evaluation approach for the Y/KPP; to evaluate stock identification monitoring tools, approaches, and opportunities available to meet specific objectives of the experimental plan; and to evaluate adult and juvenile enumeration and sampling/collection capabilities in the Y/KPP necessary to measure experimental response variables.

  1. Scientific progress as increasing verisimilitude.

    Science.gov (United States)

    Niiniluoto, Ilkka

    2014-06-01

    According to the foundationalist picture, shared by many rationalists and positivist empiricists, science makes cognitive progress by accumulating justified truths. Fallibilists, who point out that complete certainty cannot be achieved in empirical science, can still argue that even successions of false theories may progress toward the truth. This proposal was supported by Karl Popper with his notion of truthlikeness or verisimilitude. Popper's own technical definition failed, but the idea that scientific progress means increasing truthlikeness can be expressed by defining degrees of truthlikeness in terms of similarities between states of affairs. This paper defends the verisimilitude approach against Alexander Bird who argues that the "semantic" definition (in terms of truth or truthlikeness alone) is not sufficient to define progress, but the "epistemic" definition referring to justification and knowledge is more adequate. Here Bird ignores the crucial distinction between real progress and estimated progress, explicated by the difference between absolute (and usually unknown) degrees of truthlikeness and their evidence-relative expected values. Further, it is argued that Bird's idea of returning to the cumulative model of growth requires an implausible trick of transforming past false theories into true ones.

  2. Progress in Titanium Metal Powder Injection Molding

    Randall M. German

    2013-08-01

    Full Text Available Metal powder injection molding is a shaping technology that has achieved solid scientific underpinnings. It is from this science base that recent progress has occurred in titanium powder injection molding. Much of the progress awaited development of the required particles with specific characteristics of particle size, particle shape, and purity. The production of titanium components by injection molding is stabilized by a good understanding of how each process variable impacts density and impurity level. As summarized here, recent research has isolated the four critical success factors in titanium metal powder injection molding (Ti-MIM that must be simultaneously satisfied—density, purity, alloying, and microstructure. The critical role of density and impurities, and the inability to remove impurities with sintering, compels attention to starting Ti-MIM with high quality alloy powders. This article addresses the four critical success factors to rationalize Ti-MIM processing conditions to the requirements for demanding applications in aerospace and medical fields. Based on extensive research, a baseline process is identified and reported here with attention to linking mechanical properties to the four critical success factors.

    A number of studies have been conducted with the onset of secondary progressive multiple sclerosis as an inclusion criterion or an outcome of interest. However, a standardized objective definition of secondary progressive multiple sclerosis has been lacking. The aim of this work was to evaluate the accuracy and feasibility of an objective definition for secondary progressive multiple sclerosis, to enable comparability of future research studies. Using MSBase, a large, prospectively acquired, global cohort study, we analysed the accuracy of 576 data-derived onset definitions for secondary progressive multiple sclerosis and first compared these to a consensus opinion of three neurologists. All definitions were then evaluated against 5-year disease outcomes post-assignment of secondary progressive multiple sclerosis: sustained disability, subsequent sustained progression, positive disability trajectory, and accumulation of severe disability. The five best performing definitions were further investigated for their timeliness and overall disability burden. A total of 17 356 patients were analysed. The best definition included a 3-strata progression magnitude in the absence of a relapse, confirmed after 3 months within the leading Functional System and required an Expanded Disability Status Scale step ≥4 and pyramidal score ≥2. It reached an accuracy of 87% compared to the consensus diagnosis. Seventy-eight per cent of the identified patients showed a positive disability trajectory and 70% reached significant disability after 5 years. The time until half of all patients were diagnosed was 32.6 years (95% confidence interval 32-33.6) after disease onset compared with the physicians' diagnosis at 36 (35-39) years. The identified patients experienced a greater disease burden [median annualized area under the disability-time curve 4.7 (quartiles 3.6, 6.0)] versus non-progressive patients [1.8 (1.2, 1.9)]. This objective definition of secondary progressive multiple

    2015-11-01

    Prior to assessment of final ultrasound clinical competency it is important to monitor clinical progress, provide high quality feedback and encourage skills development. The role of the supervisor, mentor and assessor are fundamental to the on-going progress monitoring of ultrasound trainees. This article forms the second part of a larger project which was to elicit ultrasound practitioners' opinions on how progress should be monitored, where and by whom. An on-line questionnaire was used to gain opinions from ultrasound practitioners. Totally, 116 responses were received from professionals with an interest in ultrasound assessment. Results suggested that experienced, qualified ultrasound practitioners should undertake the role of supervisor and assessor, having been prepared for that role by the training centre. Formative monitoring should take place both within the clinical department and possibly the training centre, using a range of methods. Following completion of the training, practitioners should have a preceptorship period to consolidate their knowledge and skills for 3 to 6 months or until further competencies have been demonstrated. Formative progress monitoring should be a recognised part of ultrasound training. Essentially, staff undertaking supervision and assessor roles should be supported and trained to ensure a high quality, consistent learning experience for ultrasound trainees. Additionally, they should provide appropriate feedback to the trainee and education centre.

  11. Symptomatic Therapy and Rehabilitation in Primary Progressive Multiple Sclerosis

    2011-01-01

    Full Text Available Multiple sclerosis (MS is an autoimmune inflammatory demyelinating disease of the central nervous system and a major cause of chronic neurological disability in young adults. Primary progressive MS (PPMS constitutes about 10% of cases, and is characterized by a steady decline in function with no acute attacks. The rate of deterioration from disease onset is more rapid than relapsing remitting and secondary progressive MS types. Multiple system involvement at onset and rapid early progression have a worse prognosis. PPMS can cause significant disability and impact on quality of life. Recent studies are biased in favour of relapsing remitting patients as treatment is now available for them and they are more likely to be seen at MS clinics. Since prognosis for PPMS is worse than other types of MS, the focus of rehabilitation is on managing disability and enhancing participation, and application of a “neuropalliative” approach as the disease progresses. This chapter presents the symptomatic treatment and rehabilitation for persons with MS, including PPMS. A multidisciplinary approach optimizes the intermediate and long-term medical, psychological and social outcomes in this population. Restoration and maintenance of functional independence and societal reintegration, and issues relating to quality of life are addressed in rehabilitation processes.

    China's Free ART Program was initiated in 2002 as an emergency response to save and improve the lives of AIDS patients living mainly in impoverished rural regions of central China. With little experience in HIV/AIDS treatment and care and resource limitations, China's efforts to provide widespread access to free antiretroviral therapy has been a process fraught with difficulty. However, the Free ART Program is progressing from an emergency response to a standardized treatment and care system. The development of national guidelines, training programs, a laboratory support network, a national patient database, programs for special populations such as children and patients living with coinfections, and operational research has improved the scope and quality of the free treatment program. As of June 30,2005, a total of 19,456 patients in 28 provinces, autonomous regions, and special municipalities had received free ART.Challenges stemming from the nature of China's health system and patient population persist, but with strong government support and a diverse set of resources, China has the capacity to overcome these challenges and to provide nationwide access to high quality treatment and care.

  13. Childhood Obesity – 2010: Progress and Challenges

    2010-01-01

    Summary The worldwide prevalence of childhood obesity has increased greatly over the past 3 decades. The increasing occurrence in children of disorders, such as type 2 diabetes, is believed to be a consequence of this obesity epidemic. Much progress has been made in understanding the genetics and physiology of appetite control and from this, the elucidation of the causes of some rare obesity syndromes. However, these rare disorders have so far taught us only limited lessons on how to prevent or reverse obesity in most children. Calorie intake and activity recommendations need to be re-assessed and better quantified, on a population level, given the more sedentary life of children today. For individual treatment, the currently recommended calorie prescriptions may be too conservative given the evolving insight on the “energy gap.” Whilst quality of research in both prevention and treatment has improved, there is still a need for high-quality multi-centre trials with long-term follow-up. Meanwhile, prevention and treatment approaches that aim to increase energy expenditure and decrease intake need to continue. Most recently, the spiralling increase in obesity prevalence may be abating for children. Thus, even greater efforts need to be made on all fronts to continue this potentially exciting trend.

    In radiology, as a result of the increased utilization of digital imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), over a third of the images produced in a typical radiology department are currently in digital form, and this percentage is steadily increasing. Image compression provides a means for the economical storage and efficient transmission of these diagnostic pictures. The level of coding distortion that can be accepted for clinical diagnosis purposes is not yet well-defined. In this paper we introduce some constraints on the design of existing transform codes in order to achieve progressive image transmission efficiently. The design constraints allow the image quality to be asymptotically improved such that the proper clinical diagnoses are always possible. The modified transform code outperforms simple spatial-domain codes by providing higher quality of the intermediately reconstructed images. The improvement is 10 dB for a compression factor of 256:1, and it is as high as 17.5 dB for a factor of 8:1. A novel progressive quantization scheme is developed for optimal progressive transmission of transformed diagnostic images. Combined with a discrete cosine transform, the new approach delivers intermediately reconstructed images of comparable quality twice as fast as the more usual zig-zag sampled approach. The quantization procedure is suitable for hardware implementation.

    Tracking Clean Energy Progress 2013 (TCEP 2013) examines progress in the development and deployment of key clean energy technologies. Each technology and sector is tracked against interim 2020 targets in the IEA Energy Technology Perspectives 2012 2°C scenario, which lays out pathways to a sustainable energy system in 2050. Stark message emerge: progress has not been fast enough; large market failures are preventing clean energy solutions from being taken up; considerable energy efficiency remains untapped; policies need to better address the energy system as a whole; and energy-related research, development and demonstration need to accelerate. Alongside these grim conclusions there is positive news. In 2012, hybrid-electric vehicle sales passed the 1 million mark. Solar photovoltaic systems were being installed at a record pace. The costs of most clean energy technologies fell more rapidly than anticipated.

    Over the past ˜10 years, the topic of the nucleon's nonperturbative or intrinsic charm (IC) content has enjoyed something of a renaissance, largely motivated by theoretical developments involving quark modelers and PDF-fitters. In this talk I will briefly describe the importance of intrinsic charm to various issues in high-energy phenomenology, and survey recent progress in constraining its overall normalization and contribution to the momentum sum rule of the nucleon. I end with the conclusion that progress on the side of calculation has now placed the onus on experiment to unambiguously resolve the proton's intrinsic charm component.

    The causes of incomplete remyelination in progressive multiple sclerosis are unknown, as are the pathological correlates of the different clinical characteristics of patients with primary and secondary progressive disease. We analysed brains and spinal cords from 51 patients with progressive...... multiple sclerosis by planimetry. Thirteen patients with primary progressive disease were compared with 34 with secondary progressive disease. In patients with secondary progressive multiple sclerosis, we found larger brain plaques, more demyelination in total and higher brain loads of active demyelination...... compared with patients with primary progressive disease. In addition, the brain density of plaques with high-grade inflammation and active demyelination was highest in secondary progressive multiple sclerosis and remained ~18% higher than in primary progressive multiple sclerosis after adjustments...

  6. Declining death rates reflect progress against cancer.

    Ahmedin Jemal

    Full Text Available BACKGROUND: The success of the "war on cancer" initiated in 1971 continues to be debated, with trends in cancer mortality variably presented as evidence of progress or failure. We examined temporal trends in death rates from all-cancer and the 19 most common cancers in the United States from 1970-2006. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed trends in age-standardized death rates (per 100,000 for all cancers combined, the four most common cancers, and 15 other sites from 1970-2006 in the United States using joinpoint regression model. The age-standardized death rate for all-cancers combined in men increased from 249.3 in 1970 to 279.8 in 1990, and then decreased to 221.1 in 2006, yielding a net decline of 21% and 11% from the 1990 and 1970 rates, respectively. Similarly, the all-cancer death rate in women increased from 163.0 in 1970 to 175.3 in 1991 and then decreased to 153.7 in 2006, a net decline of 12% and 6% from the 1991 and 1970 rates, respectively. These decreases since 1990/91 translate to preventing of 561,400 cancer deaths in men and 205,700 deaths in women. The decrease in death rates from all-cancers involved all ages and racial/ethnic groups. Death rates decreased for 15 of the 19 cancer sites, including the four major cancers, with lung, colorectum and prostate cancers in men and breast and colorectum cancers in women. CONCLUSIONS/SIGNIFICANCE: Progress in reducing cancer death rates is evident whether measured against baseline rates in 1970 or in 1990. The downturn in cancer death rates since 1990 result mostly from reductions in tobacco use, increased screening allowing early detection of several cancers, and modest to large improvements in treatment for specific cancers. Continued and increased investment in cancer prevention and control, access to high quality health care, and research could accelerate this progress.

    Successful development of Heavy Ion Fusion (HIF) will require scientific and technology advances in areas of targets, drivers and chambers. Design work on heavy ion targets indicates that high gain (60-130) may be possible with a -3-6 MJ driver depending on the ability to focus the beams to small spot sizes. Significant improvements have been made on key components of heavy ion drivers, including sources, injectors, insulators and ferromagnetic materials for long-pulse induction accelerator cells, solid-state pulsers, and superconducting quadrupole magnets. The leading chamber concept for HIF is the thick-liquid-wall HYLEE-II design, which uses an array of flibe jets to protect chamber structures from x-ray, debris, and neutron damage. Significant progress has been made in demonstrating the ability to create and control the types of flow needed to form the protective liquid blanket. Progress has also been made on neutron shielding for the final focus magnet arrays with predicted lifetimes now exceeding the life of the power plant. Safety analyses have been completed for the HYLEE-II design using state-of-the-art codes. Work also continues on target fabrication and injection for HE. A target injector experiment capable of > 5 Hz operation has been designed and construction will start in 2002. Methods for mass production of hohlraum targets are being evaluated with small-scale experiments and analyses. Progress in these areas will be reviewed.

  20. Information Loss from Technological Progress

    Science.gov (United States)

    Townsend, P. D.

    2014-12-01

    Progress in electronics and optics offers faster computers, and rapid communication via the internet that is matched by ever larger and evolving storage systems. Instinctively one assumes that this must be totally beneficial. However advances in software and storage media are progressing in ways which are frequently incompatible with earlier systems and the economics and commercial pressures rarely guarantee total compatibility with earlier systems. Instead, the industries actively choose to force the users to purchase new systems and software. Thus we are moving forward with new technological variants that may have access to only the most recent systems and we will have lost earlier alternatives. The reality is that increased processing speed and storage capacity are matched by an equally rapid decline in the access and survival lifetime of older information. This pattern is not limited to modern electronic systems but is evident throughout history from writing on stone and clay tablets to papyrus and paper. It is equally evident in image systems from painting, through film, to magnetic tapes and digital cameras. In sound recording we have variously progressed from wax discs to vinyl, magnetic tape and CD formats. In each case the need for better definition and greater capacity has forced the earlier systems into oblivion. Indeed proposed interactive music systems could similarly relegate music CDs to specialist collections. The article will track some of the examples and discuss the consequences as well as noting that this information loss is further compounded by developments in language and changes in cultural views of different societies.

  1. Statins and progressive renal disease.

    Thanks to the administration of hypocholesterolemic drugs, important advances have been made in the treatment of patients with progressive renal disease. In vitro and in vivo findings demonstrate that statins, the inhibitors of HMG-CoA reductase, can provide protection against kidney diseases characterized by inflammation and/or enhanced proliferation of epithelial cells occurring in rapidly progressive glomerulonephritis, or by increased proliferation of mesangial cells occurring in IgA nephropathy. Many of the beneficial effects obtained occur independent of reduced cholesterol levels because statins can directly inhibit the proliferation of different cell types (e.g., mesangial, renal tubular, and vascular smooth muscle cells), and can also modulate the inflammatory response, thus inhibiting macrophage recruitment and activation, as well as fibrosis. The mechanisms underlying the action of statins are not yet well understood, although recent data in the literature indicate that they can directly affect the proliferation/apoptosis balance, the down-regulation of inflammatory chemokines, and the cytogenic messages mediated by the GTPases Ras superfamily. Therefore, as well as reducing serum lipids, statins and other lipid-lowering agents may directly influence intracellular signaling pathways involved in the prenylation of low molecular weight proteins that play a crucial role in cell signal transduction and cell activation. Statins appear to have important potential in the treatment of progressive renal disease, although further studies are required to confirm this in humans.

    Full Text Available Progressive collapse is a catastrophic structural phenomenon that can occur because of human-made and natural hazards. In progressive collapse mechanism, a single local failure may cause a significant deformation which then may lead to collapse of a structure. The current practices in progressive collapse analysis and design method generally focus on preventing progressive collapse due to abnormal gravity and blast loads. Progressive collapse behaviour of structures due to earthquake loads has not received as much attention. This paper presents a brief overview of the current state-of-knowledge, insights, and issues related to progressive collapse behaviour of structures caused by earthquake loading.

    Achieving and maintaining the water quality conditions necessary to protect the aquatic living resources of the Chesapeake Bay and its tidal tributaries has required a foundation of quantifiable water quality criteria. Quantitative criteria serve as a critical basis for assessing the attainment of designated uses and measuring progress toward meeting water quality goals of the Chesapeake Bay Program partnership. In 1987, the Chesapeake Bay Program partnership committed to defining the water quality conditions necessary to protect aquatic living resources. Under section 303(c) of the Clean Water Act, States and authorized tribes have the primary responsibility for adopting water quality standards into law or regulation. The Chesapeake Bay Program partnership worked with U.S. Environmental Protection Agency to develop and publish a guidance framework of ambient water quality criteria with designated uses and assessment procedures for dissolved oxygen, water clarity, and chlorophyll a for Chesapeake Bay and its tidal tributaries in 2003. This article reviews the derivation of the water quality criteria, criteria assessment protocols, designated use boundaries, and their refinements published in six addendum documents since 2003 and successfully adopted into each jurisdiction's water quality standards used in developing the Chesapeake Bay Total Maximum Daily Load.

    Granulation, the process of particle enlargement by agglomeration technique, is one of the most significant unit operations in the production of pharmaceutical dosage forms, mostly tablets and capsules. Granulation process transforms fine powders into free-flowing, dust-free granules that are easy to compress. Nevertheless, granulation poses numerous challenges due to high quality requirement of the formed granules in terms of content uniformity and physicochemical properties such as granule size, bulk density, porosity, hardness, moisture, compressibility, etc. together with physical and chemical stability of the drug. Granulation process can be divided into two types: wet granulation that utilize a liquid in the process and dry granulation that requires no liquid. The type of process selection requires thorough knowledge of physicochemical properties of the drug, excipients, required flow and release properties, to name a few. Among currently available technologies, spray drying, roller compaction, high shear mixing, and fluid bed granulation are worth of note. Like any other scientific field, pharmaceutical granulation technology also continues to change, and arrival of novel and innovative technologies are inevitable. This review focuses on the recent progress in the granulation techniques and technologies such as pneumatic dry granulation, reverse wet granulation, steam granulation, moisture-activated dry granulation, thermal adhesion granulation, freeze granulation, and foamed binder or foam granulation. This review gives an overview of these with a short description about each development along with its significance and limitations.

    Moyamoya disease (MMD) is a chronic progressive cerebrovascular disease, which can be divided into three types: ischemic, hemorrhagic, and asymptomatic. Hemorrhagic MMD has attracted considerable attention due to its distinctive imaging features and the controversy over the treatment. This report presents a comprehensive review of the literature on hemorrhagic MMD, focusing on the epidemiological characteristics, etiology and pathogenesis, imaging features, predictors of hemorrhage, and treatment options and their efficacy of hemorrhagic MMD. Hemorrhagic MMD mainly occurs in adult patients in Asian countries, and many factors may contribute to the etiology and development of this disease. Hemorrhagic MMD has two major imaging features: the dilatation and abnormal branching of anterior choroidal artery or posterior communicating artery, and multiple microbleeds, which may predict subsequent hemorrhage. The treatment for hemorrhagic MMD is not standardized, and large sample prospective randomized clinical trials may help to determine which method is better. In hemorrhagic MMD patients, more attention should be paid to cognitive function and quality of life, and these assessments should be included in the evaluation of effectiveness of treatment modalities.

    The vestibular system is a sensory system that is critically important in humans for gaze and image stability as well as postural control. Patients with complete bilateral vestibular loss are severely disabled and experience a poor quality of life. There are very few effective treatment options for patients with no vestibular function. Over the last 10 years, rapid progress has been made in developing artificial 'vestibular implants' or 'prostheses', based on cochlear implant technology. As of 2017, 13 patients worldwide have received vestibular implants and the results are encouraging. Vestibular implants are now becoming part of an increasing effort to develop artificial, bionic sensory systems, and this paper provides a review of the progress in this area.

  3. Progression of HIV in haemophilia.

    The recent elucidation of the life cycle and dynamics of the human immunodeficiency virus (HIV) and technological advances in development of the HIV RNA PCR assay for sensitive detection of viral load have revolutionized the diagnosis, management, and treatment of HIV infection. Beginning with initial infection, there is unremitting, high-level viral replication that persists throughout the course of HIV infection. The measure of the amount of virus present in plasma, HIV viral load, is the single most important predictor of HIV progression, the best indicator of immune system decline, and the best guide for initiating and monitoring antiviral treatment. Further, HIV viral load has become the new yardstick against which other markers, including CD4 number, age, chemokine receptor mutations, cytotoxic T-cell responses, and neutralizing antibody titers are assessed. For individuals with haemophilia, additional 'markers' may have significant impact on the outcome of HIV disease. Chronic factor concentrate treatment has led to transfusion-associated hepatitis, co-infection with hepatitis C (HCV), and chronic liver disease. The latter may become accelerated with HIV progression and may lead to hepatotoxicity with antiviral drug therapy. Chronic factor concentrate treatment has also been associated with immunosuppression, including both B- and T-cell immune defects. In HIV(+) haemophilic men, this immune deficit has led to lower CD4 counts with HIV progression and poorer CD4 response to antiviral drugs than in gay men. The underlying haemophilic bleeding tendency may result in significant haemorrhage with HIV-associated immune thrombocytopenia and with protease inhibitor antiretroviral therapy. Although AIDS is the leading cause of death in this group, the reduction in the size of the haemophilia population over the next two centuries is estimated to be small, and survival should improve as better antiviral therapeutics are identified.

  4. Gleason Grade Progression Is Uncommon

    Gleason grade is universally used for pathologic scoring the differentiation of prostate cancer. However, it is unknown whether prostate tumors arise well-differentiated and then progress to less differentiated forms or if Gleason grade is an early and largely unchanging feature. Prostate Specific Antigen (PSA) screening has reduced the proportion of tumors diagnosed at advanced stage, which allows assessment of this question on a population level. If Gleason grade progresses as stage does, one would expect a similar reduction in high grade tumors. We studied 1,207 Physicians’ Health Study and Health Professionals Follow-up Study participants diagnosed with prostate cancer 1982–2004 and treated with prostatectomy. We compared the distribution of grade and clinical stage across the pre-PSA and PSA screening eras. We re-reviewed grade using the ISUP 2005 revised criteria. The proportion of advanced stage tumors dropped more than six-fold, from the earliest period (12/1982–1/1993), 19.9% stage ≥T3, to the latest (5/2000–12/2004), 3% stage T3, none T4. The proportion of Gleason score ≥8 decreased substantially less, from 25.3% to 17.6%. A significant interaction between stage and diagnosis date predicting grade (p=0.04) suggests the relationship between grade and stage varies by time period. As the dramatic shift in stage since the introduction of PSA screening was accompanied by a more modest shift in Gleason grade, these findings suggest grade may be established early in tumor pathogenesis. This has implications for the understanding of tumor progression and prognosis, and may help patients diagnosed with lower grade disease feel more comfortable choosing active surveillance.

    A new self-pressurizing propulsion system has liquid thrusters and gas jet attitude control without heavy gas storage vessels. A pump boosts the pressure of a small fraction of the hydrogen peroxide, so that reacted propellant can controllably pressurize its own source tank. The warm decomposition gas also powers the pump and is supplied to the attitude control jets. The system has been incorporated into a prototype microsatellite for terrestrial maneuvering tests. Additional progress includes preliminary testing of a bipropellant thruster, and storage of unstabilized hydrogen peroxide in small sealed tanks.

  8. Genetic progression of malignant melanoma.

    Malignant melanoma of the skin is the most aggressive human cancer given that a primary tumor a few millimeters in diameter frequently has full metastatic competence. In view of that, revealing the genetic background of this potential may also help to better understand tumor dissemination in general. Genomic analyses have established the molecular classification of melanoma based on the most frequent driver oncogenic mutations (BRAF, NRAS, KIT) and have also revealed a long list of rare events, including mutations and amplifications as well as genetic microheterogeneity. At the moment, it is unclear whether any of these rare events have role in the metastasis initiation process since the major drivers do not have such a role. During lymphatic and hematogenous dissemination, the clonal selection process is evidently reflected by differences in oncogenic drivers in the metastases versus the primary tumor. Clonal selection is also evident during lymphatic progression, though the genetic background of this immunoselection is less clear. Genomic analyses of metastases identified further genetic alterations, some of which may correspond to metastasis maintenance genes. The natural genetic progression of melanoma can be modified by targeted (BRAF or MEK inhibitor) or immunotherapies. Some of the rare events in primary tumors may result in primary resistance, while further new genetic lesions develop during the acquired resistance to both targeted and immunotherapies. Only a few genetic lesions of the primary tumor are constant during natural or therapy-modulated progression. EGFR4 and NMDAR2 mutations, MITF and MET amplifications and PTEN loss can be considered as metastasis drivers. Furthermore, BRAF and MITF amplifications as well as PTEN loss are also responsible for resistance to targeted therapies, whereas NRAS mutation is the only founder genetic lesion showing any association with sensitivity to immunotherapies. Unfortunately, there are hardly any data on the

    This review outlines current progresses in polymer solar cell. Compared to traditional silicon-based photovoltaic (PV) technology, the completely different principle of optoelectric response in the polymer cell results in a novel configuration of the device and more complicated photovoltaic generation process. The conception of bulk-heterojunction (BHJ) is introduced and its advantage in terms of morphology is addressed. The main aspects including the morphology of photoactive layer, which limit the efficiency and stability of polymer solar cell, are discussed in detail. The solutions to boosting up both the efficiency and stability (lifetime) of the polymer solar cell are highlighted at the end of this review.

    The dynamics of export market exit and firm closure have found limited attention in heterogeneous-firms trade models. Accordingly, several of the predictions on exit stemming from new-new trade theory are at odds with the stylized facts. Empirically, higher productivity firms survive longer, higher...... productivity exporters are more likely to continue to export, and market exit is typically preceded by periods of contracting market shares. We show that the simple inclusion of exogenous economy wide technological progress into the standard Melitz (2003) model generates a tractable dynamic framework...

    @@ 1 Glass Industry and Refractories Industry Closely Connect 1.1 Glass Development Drives Refractories Progress Refractories are indispensable to glass industry; the rapid development of glass industry drives the growth of refractories industry. China's glass industry developed slowly before the mid 1980s. The kilns and furnaces were backward and small-scale with furnace life of only 2-3 years; glass was produced with extremely low efficiency and poor quality. During that period, refractories for glass melting furnaces had very limited varieties and inferior quality. The fused cast refractories for advanced glass melting furnaces were imported, for the materials made in China could not meet the requirements, which seriously restrained the technical progress of China's glass industry.

    Under the US Fusion Nuclear Science and Technology Development program, we have selected the Dual Coolant Lead Lithium concept (DCLL) as a reference blanket, which has the potential to be a high performance DEMO blanket design with a projected thermal efficiency of >40%. Reduced activation ferritic/martensitic (RAF/M) steel is used as the structural material. The self-cooled breeder PbLi is circulated for power conversion and for tritium breeding. A SiC-based flow channel insert (FCI) is used as a means for magnetohydrodynamic pressure drop reduction from the circulating liquid PbLi and as a thermal insulator to separate the high-temperature PbLi (~700°C) from the helium-cooled RAF/M steel structure. We are making progress on related R&D needs to address critical Fusion Nuclear Science and Facility (FNSF) and DEMO blanket development issues. When performing the function as the Interface Coordinator for the DCLL blanket concept, we had been developing the mechanical design and performing neutronics, structural and thermal hydraulics analyses of the DCLL TBM module. We had estimated the necessary ancillary equipment that will be needed at the ITER site and a detailed safety impact report has been prepared. This provided additional understanding of the DCLL blanket concept in preparation for the FNSF and DEMO. This paper will be a summary report on the progress of the DCLL TBM design and R&Ds for the DCLL blanket concept.
