    Myers, William; Winter, Steve

    2006-01-01

    The General Electric Reliable and Affordable Controls effort under the NASA Advanced Subsonic Technology (AST) Program has designed, fabricated, and tested advanced controls hardware and software to reduce emissions and improve engine safety and reliability. The original effort consisted of four elements: 1) a Hydraulic Multiplexer; 2) Active Combustor Control; 3) a Variable Displacement Vane Pump (VDVP); and 4) Intelligent Engine Control. The VDVP and Intelligent Engine Control elements were cancelled due to funding constraints and are reported here only to the state they progressed. The Hydraulic Multiplexing element developed and tested a prototype which improves reliability by combining the functionality of up to 16 solenoids and servo-valves into one component with a single electrically powered force motor. The Active Combustor Control element developed intelligent staging and control strategies for low emission combustors. This included development and tests of a Controlled Pressure Fuel Nozzle for fuel sequencing, a Fuel Multiplexer for individual fuel cup metering, and model-based control logic. Both the Hydraulic Multiplexer and Controlled Pressure Fuel Nozzle system were cleared for engine test. The Fuel Multiplexer was cleared for combustor rig test which must be followed by an engine test to achieve full maturation.

    The mission of Environmental Management`s (EM) Office of Technology Development (OTD) Innovation Investment Area is to identify and provide development support for two types of technologies that are developed to characterize, treat and dispose of DOE waste, and to remediate contaminated sites. They are: technologies that show promise to address specific EM needs, but require proof-of-principle experimentation; and (2) already proven technologies in other fields that require critical path experimentation to demonstrate feasibility for adaptation to specific EM needs. The underlying strategy is to ensure that private industry, other Federal Agencies, universities, and DOE National Laboratories are major participants in developing and deploying new and emerging technologies. To this end, about 125 different new and emerging technologies are being developed through Innovation Investment Area`s (IIA) two program elements: RDDT&E New Initiatives (RD01) and Interagency Agreements (RD02). Both of these activities are intended to foster research and development partnerships so as to introduce innovative technologies into other OTD program elements for expedited evaluation.

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this approach, EM developed a management structure and principles that led to creation of specific focus areas. These organizations were designed to focus scientific and technical talent throughout DOE and the national scientific community on major environmental restoration and waste management problems facing DOE. The focus area approach provides the framework for inter-site cooperation and leveraging of resources on common problems. After the original establishment of five major focus areas within the Office of Technology Development (EM-50), the Nuclear Materials Stabilization Task Group (NMSTG, EM-66) followed EM-50`s structure and chartered the Plutonium Focus Area (PFA). NMSTG`s charter to the PFA, described in detail later in this book, plays a major role in meeting the EM-66 commitments to the Defense Nuclear Facilities Safety Board (DNFSB). The PFA is a new program for FY96 and as such, the primary focus of revision 0 of this Technology Summary is an introduction to the Focus Area; its history, development, and management structure, including summaries of selected technologies being developed. Revision 1 to the Plutonium Focus Area Technology Summary is slated to include details on all technologies being developed, and is currently planned for release in August 1996. The following report outlines the scope and mission of the Office of Environmental Management, EM-60, and EM-66 organizations as related to the PFA organizational structure.

    Besides the issues of international consequences of science and technology developments (including information technology, biotechnology, materials technology, nuclear technology, space technology) the following topics were touched only briefly: energy and uses of nuclear power, environmental issues, and matters such as the comprehensive test-ban treaty and the way ahead -more perhaps a phased approach than a single step. The limited time available did not allow considering the role of the United Nations and any other institutional forms in these matters. There is conviction that there was enough historical evidence to suggest that there will be a need for a plurality of institutions, with different geographical, and maybe even political, imperatives. In summary, a conference such as this one at Sendai can offer the United Nations advice on the dynamics of change in sectors of science and technology, of the impact of such changes on matters related to international security - military, economic and the environment. There is belief in the maximum diffusion of science and technology with the minimum discrimination but at the same time dissemination consistent with international security. The value of co-operative efforts in research and development, in the removal of asymmetries in the international system. The removal of such asymmetries would constitute a significant step on the way ahead, to a more just and lasting equilibrium between States

    Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are commonly used biomarkers for liver damage. As well as in liver tissue, AST is also present in cardiac and skeletal muscle and in erythrocytes, making ALT the most specific marker for liver damage. Here, we describe two patients with sustained increases in ALT and AST levels. The first patient is a 79-year-old woman who developed elevated serum transaminases shortly after having a myocardial infarction. The second patient, an obese 40-year-old woman presented with increased ALT and AST levels in the absence of physical symptoms. Notably, her father died of liver cirrhosis without a history of alcohol abuse. Based upon these case reports we discuss the differential diagnostic work-up of elevated serum transaminase levels. Furthermore, we explain monitoring, test performance, reference values and analytical pitfalls of these biomarkers.

    The AstDyS online information service (http://hamilton.dm.unipi.it/astdys/) contains data on numbered and multi - opposition asteroids, including orbital elements, their uncertainty, proper elements, ephemerides with uncertainty, and more. AstDyS also provides additional scientific output computed from the raw observational data. This value added currently includes: more accurate orbits computed with advanced dynamical and observational error model s; their uncertainty, as expressed by the covariance matrix formalism; ephemerides computed on request for each observer, with uncertainty; mean and proper orbital elements (for this output, AstDyS is the primary source worldwide); statistical quality control, providing a rigorous observational error model. All this is available with a sophisticated web interface, providing multiple search functions and online computations as well as complete orbital and residual files. There are several ways in which the A stDyS service could be expanded and improved in the next future, like the explicit classification of asteroids into asteroid families, the classification of resonant asteroids, and an updated self - consistent population model (to be used, e.g., for survey simulations). The IAU Division I endorsed the proposal for AstDyS to become an IAU (permanent) service, which would include the IAU supervision of the AstDyS system, keeping under control the quality of the work and the continuous update under conditions of scientific competition.

    Landfills within the DOE Complex as of 1990 are estimated to contain 3 million cubic meters of buried waste. The DOE facilities where the waste is predominantly located are at Hanford, the Savannah River Site (SRS), the Idaho National Engineering Laboratory (INEL), the Los Alamos National Laboratory (LANL), the Oak Ridge Reservation (ORR), the Nevada Test Site (NTS), and the Rocky Flats Plant (RFP). Landfills include buried waste, whether on pads or in trenches, sumps, ponds, pits, cribs, heaps and piles, auger holes, caissons, and sanitary landfills. Approximately half of all DOE buried waste was disposed of before 1970. Disposal regulations at that time permitted the commingling of various types of waste (i.e., transuranic, low-level radioactive, hazardous). As a result, much of the buried waste throughout the DOE Complex is presently believed to be contaminated with both hazardous and radioactive materials. DOE buried waste typically includes transuranic-contaminated radioactive waste (TRU), low-level radioactive waste (LLW), hazardous waste per 40 CFR 26 1, greater-than-class-C waste per CFR 61 55 (GTCC), mixed TRU waste, and mixed LLW. The mission of the Landfill Stabilization Focus Area is to develop, demonstrate, and deliver safer,more cost-effective and efficient technologies which satisfy DOE site needs for the remediation and management of landfills. The LSFA is structured into five technology areas to meet the landfill remediation and management needs across the DOE complex. These technology areas are: assessment, retrieval, treatment, containment, and stabilization. Technical tasks in each of these areas are reviewed.

    2015-04-01

    We present the Automated Stellar Cluster Analysis package (ASteCA), a suit of tools designed to fully automate the standard tests applied on stellar clusters to determine their basic parameters. The set of functions included in the code make use of positional and photometric data to obtain precise and objective values for a given cluster's center coordinates, radius, luminosity function and integrated color magnitude, as well as characterizing through a statistical estimator its probability of being a true physical cluster rather than a random overdensity of field stars. ASteCA incorporates a Bayesian field star decontamination algorithm capable of assigning membership probabilities using photometric data alone. An isochrone fitting process based on the generation of synthetic clusters from theoretical isochrones and selection of the best fit through a genetic algorithm is also present, which allows ASteCA to provide accurate estimates for a cluster's metallicity, age, extinction and distance values along with its uncertainties. To validate the code we applied it on a large set of over 400 synthetic MASSCLEAN clusters with varying degrees of field star contamination as well as a smaller set of 20 observed Milky Way open clusters (Berkeley 7, Bochum 11, Czernik 26, Czernik 30, Haffner 11, Haffner 19, NGC 133, NGC 2236, NGC 2264, NGC 2324, NGC 2421, NGC 2627, NGC 6231, NGC 6383, NGC 6705, Ruprecht 1, Tombaugh 1, Trumpler 1, Trumpler 5 and Trumpler 14) studied in the literature. The results show that ASteCA is able to recover cluster parameters with an acceptable precision even for those clusters affected by substantial field star contamination. ASteCA is written in Python and is made available as an open source code which can be downloaded ready to be used from its official site.

  19. Mixed waste focus area alternative technologies workshop

    1995-01-01

    This report documents the Mixed Waste Focus Area (MWFA)-sponsored Alternative Technology Workshop held in Salt Lake City, Utah, from January 24--27, 1995. The primary workshop goal was identifying potential applications for emerging technologies within the Options Analysis Team (OAT) ''wise'' configuration. Consistent with the scope of the OAT analysis, the review was limited to the Mixed Low-Level Waste (MLLW) fraction of DOE's mixed waste inventory. The Los Alamos team prepared workshop materials (databases and compilations) to be used as bases for participant review and recommendations. These materials derived from the Mixed Waste Inventory Report (MWIR) data base (May 1994), the Draft Site Treatment Plan (DSTP) data base, and the OAT treatment facility configuration of December 7, 1994. In reviewing workshop results, the reader should note several caveats regarding data limitations. Link-up of the MWIR and DSTP data bases, while representing the most comprehensive array of mixed waste information available at the time of the workshop, requires additional data to completely characterize all waste streams. A number of changes in waste identification (new and redefined streams) occurred during the interval from compilation of the data base to compilation of the DSTP data base with the end result that precise identification of radiological and contaminant characteristics was not possible for these streams. To a degree, these shortcomings compromise the workshop results; however, the preponderance of waste data was linked adequately, and therefore, these analyses should provide useful insight into potential applications of alternative technologies to DOE MLLW treatment facilities

    The general issues regarding NHR and desalination facility joint operation for potable water production are briefly considered. AST-500 reactor plant and DOU GTPA-type evaporating desalination facilities, both relying on proven technology and solid experience of construction and operation, are taken as a basis for the design of a large-output nuclear desalination complex. Its main design characteristics are given. Similarity of NHR operation for a heating grid and a desalination facility in respect of reactor plant operating conditions and power regulation principles is pointed out. The issues of nuclear desalination complexes composition are discussed briefly as well. (author)

  1. Limiting the testing of AST: a diagnostically nonspecific enzyme.

    Science.gov (United States)

    Xu, Qian; Higgins, Trefor; Cembrowski, George S

    2015-09-01

    Annually, millions of pairs of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) tests are ordered. These enzymes are highly correlated, and ALT is far more specific diagnostically than AST. To reduce AST testing, we suggest measuring AST only when ALT exceeds a predetermined limit. We derived the proportions of elevated ASTs that would not be measured based on 15 months of paired inpatient and outpatient ALT and AST data. For inpatients, a 35 U/L ALT limit for initiating AST testing would reduce AST testing by 51%, missing only 3% and 7.5% of ASTs exceeding 50 U/L and 35 U/L, respectively. In outpatients, AST testing can be reduced by more than 65%, with fewer missed elevated ASTs (0.5% and 2% of the ASTs exceeding 50 U/L and 35 U/L, respectively). Conservatively, $100 million could be saved annually in the US health care budget by selectively limiting AST testing in just the US outpatient environment.

    The exponential increase of launch system size.and cost.with delta-V makes missions that require large total impulse cost prohibitive. Led by NASA fs Marshall Space Flight Center, a team from government, industry, and academia has developed a flight demonstration mission concept of an integrated electrodynamic (ED) tethered satellite system called PROPEL: \\Propulsion using Electrodynamics.. The PROPEL Mission is focused on demonstrating a versatile configuration of an ED tether to overcome the limitations of the rocket equation, enable new classes of missions currently unaffordable or infeasible, and significantly advance the Technology Readiness Level (TRL) to an operational level. We are also focused on establishing a far deeper understanding of critical processes and technologies to be able to scale and improve tether systems in the future. Here, we provide an overview of the proposed PROPEL mission. One of the critical processes for efficient ED tether operation is the ability to inject current to and collect current from the ionosphere. Because the PROPEL mission is planned to have both boost and deboost capability using a single tether, the tether current must be capable of flowing in both directions and at levels well over 1 A. Given the greater mobility of electrons over that of ions, this generally requires that both ends of the ED tether system can both collect and emit electrons. For example, hollow cathode plasma contactors (HCPCs) generally are viewed as state-of-the-art and high TRL devices; however, for ED tether applications important questions remain of how efficiently they can operate as both electron collectors and emitters. Other technologies will be highlighted that are being investigated as possible alternatives to the HCPC such as Solex that generates a plasma cloud from a solid material (Teflon) and electron emission (only) technologies such as cold-cathode electron field emission or photo-electron beam generation (PEBG) techniques

    The mission of the Engineering Research, Development, and Technology Program at Lawrence Livermore National Laboratory (LLNL) is to develop the knowledge base, process technologies, specialized equipment, tools and facilities to support current and future LLNL programs. Engineering`s efforts are guided by a strategy that results in dual benefit: first, in support of Department of Energy missions, such as national security through nuclear deterrence; and second, in enhancing the nation`s economic competitiveness through their collaboration with US industry in pursuit of the most cost-effective engineering solutions to LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) identify key technologies relevant to LLNL programs where they can establish unique competencies, and (2) conduct high-quality research and development to enhance their capabilities and establish themselves as the world leaders in these technologies. To focus Engineering`s efforts, technology thrust areas are identified and technical leaders are selected for each area. The thrust areas are comprised of integrated engineering activities, staffed by personnel from the nine electronics and mechanical engineering divisions, and from other LLNL organizations. This annual report, organized by thrust area, describes Engineering`s activities for fiscal year 1995. The report provides timely summaries of objectives methods, and key results from eight thrust areas: computational electronics and electromagnetics; computational mechanics; microtechnology; manufacturing technology; materials science and engineering; power conversion technologies; nondestructive evaluation; and information engineering.

    The mission of the Engineering Research, Development, and Technology Program at Lawrence, Livermore National Laboratory (LLNL) is to develop the technical staff and the technology needed to support current and future LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) to identify key technologies and (2) conduct high quality work to enhance our capabilities in these key technologies. To help focus our efforts, we identify technology thrust areas and select technical leaders for each area. The thrust areas are integrated engineering activities and, rather than being based on individual disciplines, they are staffed by personnel from Electronics Engineering, Mechanical Engineering, and other LLNL organizations, as appropriate. The thrust area leaders are expected to establish strong links to LLNL program leaders and to industry; to use outside and inside experts to review the quality and direction of the work; to use university contacts to supplement and complement their efforts; and to be certain that we are not duplicating the work of others. The thrust area leader is also responsible for carrying out the work that follows from the Engineering Research, Development, and Technology Program so that the results can be applied as early as possible to the needs of LLNL programs.

    To discover and probe the properties of new particles, we need to collide highly energetic particles. The Tevatron at Fermilab has collided protons and anti-protons at very high energies. These collisions produce short lived and stable particles, some known and some previously unknown. The CDF detector is used to study the products of such collisions and discover new elementary particles. To study the interaction between high energy charged particles and the detector materials often requires development of new instruments. Thus this dissertation involves a measurement at a contemporary experiment and development of technologies for related future experiments that will build on the contemporary one.

    Full Text Available The ratio of aspartate aminotransferase (AST to alanine aminotransferase (ALT is of great interest as a possible novel marker of metabolic syndrome. However, longitudinal studies emphasizing the incremental predictive value of the AST-to-ALT ratio in diagnosing individuals at higher risk of developing metabolic syndrome are very scarce. Therefore, our study aimed to evaluate the AST-to-ALT ratio as an incremental predictor of new onset metabolic syndrome in a population-based cohort study.The population-based cohort study included 2276 adults (903 men and 1373 women aged 40-70 years, who participated from 2005-2008 (baseline without metabolic syndrome and were followed up from 2008-2011. Metabolic syndrome was defined according to the harmonized definition of metabolic syndrome. Serum concentrations of AST and ALT were determined by enzymatic methods.During an average follow-up period of 2.6-years, 395 individuals (17.4% developed metabolic syndrome. In a multivariable adjusted model, the odds ratio (95% confidence interval for new onset of metabolic syndrome, comparing the fourth quartile to the first quartile of the AST-to-ALT ratio, was 0.598 (0.422-0.853. The AST-to-ALT ratio also improved the area under the receiver operating characteristic curve (AUC for predicting new cases of metabolic syndrome (0.715 vs. 0.732, P = 0.004. The net reclassification improvement of prediction models including the AST-to-ALT ratio was 0.23 (95% CI: 0.124-0.337, P<0.001, and the integrated discrimination improvement was 0.0094 (95% CI: 0.0046-0.0143, P<0.001.The AST-to-ALT ratio independently predicted the future development of metabolic syndrome and had incremental predictive value for incident metabolic syndrome.

    Electrical capacitance tomography (ECT) is a promising imaging technology of permittivity distributions in multiphase flow. To reduce the effect of charging phenomenon on ECT measurement, an improved extreme learning machine method combined with adaptive soft-thresholding (AST-ELM) is presented and studied for image reconstruction. This method can provide a nonlinear mapping model between the capacitance values and medium distributions by using machine learning but not an electromagnetic-sensitive mechanism. Both simulation and experimental tests are carried out to validate the performance of the presented method, and reconstructed images are evaluated by relative error and correlation coefficient. The results have illustrated that the image reconstruction accuracy by the proposed AST-ELM method has greatly improved than that by the conventional methods under the condition with charging object.

    There is a histologic similarity between nonalcoholic steatohepatitis and alcoholic liver disease and in some cases differential diagnosis may be difficult, since some patients do not report abusive alcohol consumption. Evaluating the usefulness of setting the rate AST/ALT for the differential diagnosis of nonalcoholic steatohepatitis and alcoholic liver disease. Twenty nine obese patients with nonalcoholic steatohepatitis were compared with 28 patients with alcoholic liver disease. The diagnosis of nonalcoholic steatohepatitis was made after exclusion of other causes of liver disease and by histologic findings of, at least, macrovesicular steatosis and hepatocellular necrosis. In patients with nonalcoholic steatohepatitis the medium AST value was 52.3 +/- 21.2 U/L and ALT of 90.1 +/- 37.9 U/L, being the AST/ALT rate lower than 1 in all patients. In patients with alcoholic liver disease the medium AST value was 140 +/- 82.5 U/L and ALT was 50.6 +/- 40.3 U/L. The rate was higher than 1 in all cases and higher than 2 in 24 (85.7%), being statistically significant when compared with patients with nonalcoholic steatohepatitis. The AST/ALT rate seems to be useful in the differential diagnosis of liver diseases, while lower than 1 is highly suggestive of nonalcoholic steatohepatitis.

    Background: Alanine aminotransferase (ALT) is frequently used as the sole biochemical marker for chronic hepatitis C (CHC), however, its value may be normal in cases with active disease. Recently, aspartate aminotransferase (AST) has been suggested as a useful predictor of liver pathology and conflicting results were obtained by using AST/ALT ratio to predict cirrhosis. Aims: To evaluate clinical utility of serum ALT and AST in CHC. Methods: The charts of 133 patients with CHC, whose ALT and AST were simultaneously tested from 1994 to 1996, were reviewed. ALT and AST were analyzed for both the entire cohort of patients and subgroups stratified for histopathology, age, gender, alcohol consumption, and risk factors of transmission. In 53 patients, the AST/ALT ratio was evaluated during interferon treatment. Results: The elevation of ALT significantly correlated with that of AST (r=0.79). The AST/ALT ratio increased with liver histological progression. The ratio >/=1 was predominantly in cirrhotic patients. During treatment the ratio increased. The AST remained elevated in eight of the 33 patients in whom the ALT had returned to normal during and after treatment. Conclusions: Both ALT and AST are useful markers for CHC. However, the AST may elevate alone, suggesting that measuring AST may be useful when the ALT is consistently normal. The AST/ALT ratio varies in different patients but increases with histological progression of fibrosis. An AST/ALT ratio >/=1 is highly suggestive of the presence of cirrhosis.

  20. Radioactive Tank Waste Remediation Focus Area. Technology summary

    1995-06-01

    In February 1991, DOE's Office of Technology Development created the Underground Storage Tank Integrated Demonstration (UST-ID), to develop technologies for tank remediation. Tank remediation across the DOE Complex has been driven by Federal Facility Compliance Agreements with individual sites. In 1994, the DOE Office of Environmental Management created the High Level Waste Tank Remediation Focus Area (TFA; of which UST-ID is now a part) to better integrate and coordinate tank waste remediation technology development efforts. The mission of both organizations is the same: to focus the development, testing, and evaluation of remediation technologies within a system architecture to characterize, retrieve, treat, concentrate, and dispose of radioactive waste stored in USTs at DOE facilities. The ultimate goal is to provide safe and cost-effective solutions that are acceptable to both the public and regulators. The TFA has focused on four DOE locations: the Hanford Site in Richland, Washington, the Idaho National Engineering Laboratory (INEL) near Idaho Falls, Idaho, the Oak Ridge Reservation in Oak Ridge, Tennessee, and the Savannah River Site (SRS) in Aiken, South Carolina

    The Microwave Anisotropy Probe (MAP) was launched to create a full-sky map of the cosmic microwave background. MAP incorporates two modified Lockheed Martin AST-201 (Autonomous Star Tracker) star trackers. The AST-201 employs an eight element radiation hardened lens assembly which is used to focus an image on a charge coupled device (CCD). The CCD image is then processed by a star identification algorithm which outputs a three-axis attitude. A CCD-shift algorithm called Time Delayed Integration (TDI) was also included in each star tracker. In order to provide some radiation effect filtering during MAP's three to five phasing loop passes through the Van Allen radiation belts, a simple pixel filtering scheme was implemented, rather than using a more complex, but more robust windowing algorithm. The trackers also include a fiber optic data interface. This paper details the ground testing that was accomplished on the MAP trackers.

    Abstract The aspartat aminotransferase (AST)/alanin aminotransferase (ALT) (De-Ritis) ratio (AAR) is an easily applicable blood test. An elevated AAR on the one hand has been associated with an increase in nonalcoholic fatty liver disease (NAFLD). NAFLD on the other hand is associated with an increase in cardiovascular disease, all-cause mortality, and diabetes. As the AAR is also elevated in case of muscular damage, we investigated AAR and its association with critical limb ischemia (CLI) in...

    Arxula adeninivorans is dimorphic yeast with unusual biochemical and physiological characteristic. It is thermo- and osmo- resistance and it can use a wide range of carbon sources for growth. One kinase of the HOG pathway, the MAPKKK is encoded by ASTE11 gene which was isolated from A. adeninivorans. The aste11 mutant was achieved by gene disruption procedure. The Sck1p gene encoding MAPKKK in S. cerevisiae can complement with aste11 mutation. Growth rate of G1211/pAL-ALEU2m, G1211/pAL-ALEU2m-ASTE11 (over-expression transformants) and IS1 [aleu2 aste11 ALEU2] (aste11 mutant), the ASTE11 expression level dose not correlates with salt resistance. However, the growth rate of G1211/pAL-ALEU2m, G1211/pAL-ALEU2m-ASTE11 (over-expression transformants) and IS1 [aleu2 aste11::ALEU2] (aste11 mutant) and the response to thermo stress were affected in the deleted mutant, the Aste11p influenced the thermo resistance of A. adeninivorans. The MAPKKK encoding by STE11 gene from various yeast species is involved in the mating process. The mutant strains and their transformants were lost the capacity to mate. Assessment of the ASTE11 promoter activity with lacZ reporter gene confirmed its inducibility by osmolaytes.

    2008-07-01

    OG21 (www.OG21.org) Norway's official technology strategy for the petroleum sector issued a revised strategy document in November 2005 (new strategy planned in 2009). In this document 'Subsea processing and transport' was identified as one of the eight new technology target areas (TTAs). The overall OG21 strategy document is on an aggregated level, and therefore the Board of OG21 decided that a sub-strategy for each TTA was needed. This document proposes the sub-strategy for the technology target area 'Subsea processing and transport' which covers the technology and competence necessary to effectively transport well stream to a platform or to onshore facilities. This includes multiphase flow modelling, flow assurance challenges to avoid problems with hydrates, asphaltenes and wax, subsea or downhole fluid conditioning including bulk water removal, and optionally complete water removal, and sand handling. It also covers technologies to increase recovery by pressure boosting from subsea pumping and/or subsea compression. Finally it covers technologies to facilitate subsea processing such as control systems and power supply. The vision of the Subsea processing and transport TTA is: Norway is to be the leading international knowledge- and technology cluster in subsea processing and transport: Sustain increased recovery and accelerated production on the NCS by applying subsea processing and efficient transport solutions; Enable >500 km gas/condensate multiphase well stream transport; Enable >200 km oil-dominated multiphase well stream transport; Enable well stream transport of complex fluids; Enable subsea separation, boosting compression, and water injection; Enable deepwater developments; Enable environmentally friendly and energy efficient field development. Increase the export of subsea processing and transport technology: Optimize technology from the NCS for application worldwide; Develop new technology that can meet the challenges found in

    By 2020, desalination and water purification technologies are expected to contribute significantly to ensure a safe, sustainable, affordable and adequate water supply. The cost of producing water from the current generation desalination technologies has declined over time at a rate of only approximately 4% per year. So we need to accelerate our research and development (R and D) activities with a near and long term objective for evolution of current generation desalination technology and to create revolutionary next generation advanced desalination and water purification technologies which will offer a promise of step reduction in cost of producing water. There are five broad technological areas-thermal technologies, membrane technologies, alternate technologies, concentrate management technologies, reuse and recycle technologies that encompass the spectrum of desalination technology. In this paper high priority research areas in all the above technologies areas are discussed to make decision about research direction that will help to mitigate our nation's future water supply challenges.

    Revolutionary progress in the photonic technology provides the ability to develop military systems of new properties not possible to obtain with the use of classical technologies. In recent years, this progress has resulted in developing advanced, complex, multifunctional and relatively cheap Photonic Integrated Circuits (PIC) or Hybrid Photonics Circuits (HPC) built of a collection of standardized optical, optoelectronic and photonic components. This idea is similar to the technology of Electronic Integrated Circuits, which has revolutionized the microelectronic market. The novel approach to photonic technology is now revolutionizing the photonics' market. It simplifies the photonics technology and enables creation of technological centers for designing, development and production of advanced optical and photonic systems in the EU and other countries. This paper presents some selected photonic technologies and their impact on such defense systems like radars, radiolocation, telecommunication, and radio-communication systems.

    Background Elevated aminotransferase levels are commonly associated with compromised hepatic integrity from various insults. In sickle cell disease, aspartate transaminase (AST) is also released via intravascular hemolysis.

  15. Can AST/ALT ratio indicate recovery after acute paracetamol poisoning?

    2015-03-01

    Paracetamol (acetaminophen or APAP) is the most common pharmaceutical exposure in the US. Elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels indicate hepatic toxicity. AST and ALT levels rise in similar proportions but later decline at different rates, with AST falling more rapidly than ALT. To determine whether the AST/ALT ratio can indicate that a patient has passed the time of peak AST concentration. We retrospectively identified cases of patients hospitalized for acute APAP poisoning by querying the pharmacy database of all patients treated with acetylcysteine (NAC) from January 1, 2001 to March 19, 2013. We included all patients with severe APAP poisoning, defined as AST or ALT greater than 1000 IU/L. Patients who were given NAC for other indications, those without APAP poisoning, and those receiving liver transplantation were excluded. We then recorded paired AST and ALT concentrations from each patient's hospital course. We classified each pair as clearly post-peak or not, and calculated the AST/ALT ratio for each pair of values. We compared different thresholds of AST/ALT ratio in increments of 0.1 to find the optimal value that reliably indicated resolving transaminases. We identified 1820 patients who received NAC during the study period. Of these, 333 received NAC for suspected poisoning by APAP. After excluding patients without severe APAP poisoning, other diagnoses explaining transaminase elevations, and patients who underwent liver transplantation, we had 37 evaluable patients with 343 evaluable pairs of AST and ALT concentrations. An AST/ALT ratio less than or equal to 0.4 was 99% sensitive for identifying patients with resolving transaminases. An AST/ALT ratio less than or equal to 0.4 following severe hepatoxicity from paracetamol poisoning appears to be highly predictive of recovery in patients treated with NAC. This has potential to be an indicator of safe discontinuation of NAC treatment.

    Full Text Available Background Elevated aminotransferase levels are commonly associated with compromised hepatic integrity from various insults. In sickle cell disease, aspartate transaminase (AST is also released via intravascular hemolysis. This study was done to determine the pattern of changes in AST and alanine transaminase (ALT, in particular the AST:ALT ratio, and to relate these to the hemolytic state, which we consider to be more important than hepatic and cardiac dysfunction in some individuals with sickle cell disease. Methods Serum aminotransferase levels were measured in 330 subjects with sickle cell disease, as well as hemoglobin, reticulocytes, and lactate dehydrogenase. The AST:ALT ratio was designated as a hemolytic marker, and simple and multivariate regression analyses were carried out between this ratio and other hemolytic markers. Results Mean AST and ALT levels were 48.24 % 27.78 and 26.48 % 22.73 U/L, respectively. However, for 49 subjects without sickle cell disease, mean AST and ALT levels were the same, ie, 23.0 U/L. In the subjects with sickle cell disease, the increases in AST levels were far higher than for ALT, supporting its release via intravascular hemolysis. In 95.8% of the subjects with sickle cell disease, the AST:ALT ratio was > 1, but our results did not suggest overt malfunctioning of the liver and heart in the majority of subjects. Conclusion Regression analyses support the use of the AST:ALT ratio as a hemolytic marker, because it has an inverse association with the hemoglobin level. Whether in steady state or in crisis, provided hepatic and cardiac integrity has not been compromised, subjects with sickle cell disease would have higher AST levels due to the hemolytic nature of the condition. This is the first report highlighting the AST:ALT ratio in sickle cell disease.

    The ratio of serum aspartate aminotransferase to alanine aminotransferase (AST/ALT ratio) has been proposed as a noninvasive method of assessing liver fibrosis and cirrhosis. Our aims were to confirm the usefulness of the AST/ALT ratio in diagnosing cirrhosis noninvasively as well as to verify the existence of a relationship between the ratio and liver functional impairment. In all, 348 patients (177 with chronic hepatitis, 171 with cirrhosis) were retrospectively evaluated and the AST/ALT ratio was related to monoethyl glycine xylidide (MEGX) formation. Moreover, in a subgroup of 54 patients we analyzed the relationships among the AST/ALT ratio and indocyanine green clearance and half-life. The AST/ALT ratio was able to separate patients with mild fibrosis from those with severe fibrosis and cirrhosis. The AST/ALT ratio, MEGX, prothrombin activity, and platelet count were selected by multivariate analysis as variables associated with cirrhosis. The AST/ALT ratio showed significant correlations both with MEGX formation and with indocyanine green clearance and half-life. The alterations of indocyanine green kinetics, which depend upon liver blood flow and uptake, were likely due to progressive fibrosis. These findings might partially explain the increase in the AST/ALT ratio as disease progresses.

    The AST/ALT ratio was estimated in 182 dogs infected with Babesia canis. Among these dogs 65 had anaemia and 68 were azotaemic. Student's t test was used to compare means of the AST/ALT ratio in anaemic and non-anaemic dogs, and in azotaemic and non-azotaemic dogs (p < 0.05). The differences in AST/ALT ratio between anaemic (1.52 +/- 1.15) and non-anaemic (1.76 +/- 1.34) dogs were statistically insignificant (p = 0.23), however, the comparison of AST/ALT ratio between azotaemic (2.68 +/- 1.52) and non-azotaemic (1.08 +/- 0.53) dogs revealed a significantly higher value of this index in azotaemic dogs (p = 0.00). The present results suggest that kidney injury contributed to increased AST activity in these dogs.

    We have conducted an unprecedented survey of submillimeter galaxies (SMGs) using the 144 pixel bolometer camera AzTEC mounted on the ASTE 10-m dish in Chile. We have already obtained many (>20) wide (typically 12' × 12' or wider) and deep (1 σ sensitivity of 0.5-1.0 mJy) 1.1 mm continuum images of known blank fields and over-density regions/protoclusters across a wide range of redshifts with a spatial resolution of ˜ 30''. It has resulted in the numerous (˜ a few 100, almost equivalent to the total number of the previously known SMGs) new and secure detections of SMGs. In this paper, we present initial results of two selected fields, SSA 22 and AKARI Deep Field South (ADF-S). A significnat clustering of bright SMGs toward the density peak of LAEs is found in SSA 22. We derived the differential and cumulative number counts from the detected sources in ADF-S, which probe the faintest flux densities (down to ˜1 mJy) among 1-mm blank field surveys to date.

The thrust area leaders are expected to establish strong links to LLNL program leaders and to industry; to use outside and inside experts to review the quality and direction of the work; to use university contacts to supplement and complement their efforts; and to be certain that we are not duplicating the work of others. This annual report, organized by thrust area, describes activities conducted within the Program for the fiscal year 1992. Its intent is to provide timely summaries of objectives, theories, methods, and results. The nine thrust areas for this fiscal year are: Computational Electronics and Electromagnetics; Computational Mechanics; Diagnostics and Microelectronics; Emerging Technologies; Fabrication Technology; Materials Science and Engineering; Microwave and Pulsed Power; Nondestructive Evaluation; and Remote Sensing and Imaging, and Signal Engineering.

    Abstract The aspartat aminotransferase (AST)/alanin aminotransferase (ALT) (De-Ritis) ratio (AAR) is an easily applicable blood test. An elevated AAR on the one hand has been associated with an increase in nonalcoholic fatty liver disease (NAFLD). NAFLD on the other hand is associated with an increase in cardiovascular disease, all-cause mortality, and diabetes. As the AAR is also elevated in case of muscular damage, we investigated AAR and its association with critical limb ischemia (CLI) in peripheral arterial occlusive disease (PAOD) patients. In our cross-sectional study, we included 1782 PAOD patients treated at our institution from 2005 to 2010. Patients with chronic alcohol consumption (>20 g/day) were excluded. AAR was calculated and the cohort was categorized into tertiles according to the AAR. An optimal cut-off value for the continuous AAR was calculated by applying a receiver operating curve analysis to discriminate between CLI and non-CLI. In our cohort, occurrence of CLI significantly increased with an elevation in AAR. As an optimal cut-off value, an AAR of 1.67 (sensitivity 34.1%, specificity 81.0%) was identified. Two groups were categorized, 1st group containing 1385 patients (AAR  1.67). CLI was more frequent in AAR > 1.67 patients (166 [41.9%]) compared to AAR  1.67 was associated with an odds ratio (OR) of 2.0 (95% confidence interval [CI] 1.7–2.3) for CLI even after adjustment for other well-established vascular risk factors. An increased AAR is significantly associated with patients at high risk for CLI and other cardiovascular endpoints. The AAR is a broadly available and cheap marker, which might be useful to highlight patients at high risk for vascular endpoints. PMID:27310963

    Full Text Available Abstract Background MCAD-deficiency is the most common inborn error of fatty acid oxidation now included in many newborn screening programms using MS/MS. During prolonged catabolic episodes, patients may suffer from metabolic decompensation with dysfunction of liver, skeletal- and heart muscle as well as brain. In anabolism, neither clinical symptoms nor biochemical signs of organ dysfunction occur. Case presentation We report a female patient with MCAD-deficiency in whom at the age of 11 years isolated AST-elevation was found without any clinical or biochemical signs of organ dysfunction. We showed by polyethylene glycol precipitation that macro-AST formation was responsible for this biochemical finding. AST was probably complexed with immunoglobulins possibly related to an allergic disposition. Macro-AST formation is not a special feature of MCAD-deficiency but rather a non-specific, coincidental finding which also occurs in healthy individuals. The general practitioner consulted by the patient before coming to our outpatient clinic for inborn errors of metabolism was worried that isolated AST-elevation indicated cell damage in MCAD-deficiency. He ordered further diagnostic tests like ultrasound, ECG and echocardiography without any pathology. Conclusion In isolated AST-elevation, macro-AST has to be considered in order to avoid unnecessary, costly and invasive evaluation. This is not only true for healthy persons but for patients with chronic diseases like MCAD as well.

    High levels of liver enzymes GGT, ALT and AST are predictive of disease and all-cause mortality and can reflect liver injury, fatty liver and/or oxidative stress. Variation in GGT, ALT and AST levels is heritable. Moderation of the heritability of these liver enzymes by age and sex has not often been explored, and it is not clear to what extent non-additive genetic and shared environmental factors may play a role. To examine the genetic architecture of GGT, ALT and AST, plasma levels were ass...

    The Assistant Secretary for the Office of Environmental Management (EM) at the US DOE initiated a new approach in August, 1993 to environmental research and technology development. The key features of this new approach included establishment of five focus areas and three crosscutting technology programs, which overlap the boundaries of the focus areas. The five focus areas include the Contaminant Plumes Containment and Remediation; Mixed Waste Characterization, Treatment, and Disposal; High-Level Waste Tank Remediation, Landfill Stabilization, and Decontamination and Decommissioning Focus Areas. The three crosscutting technologies programs include Characterization, Monitoring, and Sensor Technology; Efficient Separations and Processing; and Robotics. The DOE created the Mixed Waste Characterization, Treatment, and Disposal Focus Area (MWFA) to develop and facilitate implementation of technologies required to meet its commitments for treatment of mixed wastes. To accomplish this goal, the technology deficiencies must be identified and categorized, the deficiencies and needs must be prioritized, and a technical baseline must be established that integrates the requirements associated with these needs into the planned and ongoing environmental research and technology development activities supported by the MWFA. These steps are described

    2004-01-01

    To assess the place of AST/ALT ratio (the ratio of serum aspartate aminotransferase to serum alanine aminotransferase) as a diagnostic marker in medical populations. Laboratory tests were viewed retrospectively in three groups of patients: 313 patients with alcohol dependence, consecutively admitted to an alcohol and drug treatment unit for treatment of withdrawal (W) symptoms, 78 patients with alcohol abuse or dependence consecutively admitted to surgical or medical wards with various primary somatic (S) diagnoses (e.g. respiratory, gastrointestinal and metabolic), and 48 consecutive patients with alcohol abuse or dependence admitted to surgical or medical wards for treatment of alcohol-related liver cirrhosis and its complications (C). Comparison between groups was made of the pattern of patients' AST/ALT ratios using, for Groups S and C, laboratory data from patients' first admission for their condition. There was a significant rise in the AST/ALT ratio from the W to the S patients, and from the S to the C patients. In the W group, the ratio was or = 2. In the C group, 69% had a ratio > or = 2, and 8% a ratio < or = 1.0. The mean ratio was midway in the S group. In the C group, there was a progressive decline in aspartate (AST/ALT) ratios after admission. Most patients with high alcohol consumption but without severe liver disease do not have an AST/ALT ratio above 1. High AST/ALT ratio suggests advanced alcoholic liver disease.

    Full Text Available Aim. Chronic kidney disease (CKD represents endothelial dysfunction. Monocyte adhesion is recognized as the initial step of arteriosclerosis. Indoxyl sulfate (IS is considered to be a risk factor for arteriosclerosis in CKD. Oral adsorbent AST-120 retards deterioration of renal function, reducing accumulation of IS. In the present study, we determined the monocyte adhesion in the adenine-induced uremic rats in vivo and effects of AST-120 on the adhesion molecules. Methods. Twenty-four rats were divided into control, control+AST-120, adenine, and adenine+AST-120 groups. The number of monocytes adherent to the endothelium of thoracic aorta by imaging the entire endothelial surface and the mRNA expressions of adhesion and atherosclerosis-related molecules were examined on day 49. The mRNA expressions of ICAM-1 and VCAM-1 in human umbilical vein endothelial cells were also examined. Results. Adenine increased the number of adherent monocytes, and AST-120 suppressed the increase. The monocyte adhesion was related to serum creatinine and IS in sera. Overexpression of VCAM-1 and TGF-β1 mRNA in the arterial walls was observed in uremic rats. IS induced increase of the ICAM-1 and VCAM-1 mRNA expressions in vitro. Conclusion. It appears that uremic condition introduces the monocyte adhesion to arterial wall and AST-120 might inhibit increasing of the monocyte adherence with CKD progression.

    The American Society of Transplantation (AST) and American Society of Transplant Surgeons (ASTS) convened a workshop on June 2-3, 2014, to explore increasing both living and deceased organ donation in the United States. Recent articles in the lay press on illegal organ sales and transplant tourism highlight the impact of the current black market in kidneys that accompanies the growing global organ shortage. We believe it important not to conflate the illegal market for organs, which we reject in the strongest possible terms, with the potential in the United States for concerted action to remove all remaining financial disincentives for donors and critically consider testing the impact and acceptability of incentives to increase organ availability in the United States. However, we do not support any trials of direct payments or valuable considerations to donors or families based on a process of market-assigned values of organs. This White Paper represents a summary by the authors of the deliberations of the Incentives Workshop Group and has been approved by both AST and ASTS Boards. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

In order to solve such problems, there are different solutions one of which is mobile health technology. Being small and user-friendly, easy to enter data and having low expense are some of its advantages. This study aims to define the association between awareness of medical students in clinical stage about mobile health technology application and the rate of their using this technology in educational hospital of Isfahan in 2011. The study is a cross-sectional analytical application research. Sixty medical students were selected as samples from a society of 240 medical students. A researcher-made questionnaire was used. The questionnaire included 21 multiple choice and 15 yes no questions, which were corrected to reach a score. A researcher-made checklist with 5-fold Likert scale was used to define the rate of applying such technology. The reliability of questionnaire was confirmed through a test-retest. The collected data were analyzed with the help of SPSS software in descriptive and deductive statistics level. The highest percentage of awareness about mobile health technology among medical students in the clinical stage of Azzahra educational hospital is 45.6 in nature areas, and their lowest percentage of awareness is 17.8 in the infrastructure area. In addition, their mean awareness of all areas is 54.4. The highest percentage of using mobile health technology by medical students is 14.6 in the education area, and their lowest percentage of usage is 6.8 in the treatment area. Their mean usage of all areas is 9.4 as well. The rate of awareness and application of mobile health technology is not favorable. Except for treatment, there is no significant association between the rate of awareness and application of mobile health technology.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II (this volume) describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Specific INEL problem areas/contaminants are identified along with technology solutions, the status of the technologies, precise science and technology needs, and implementation requirements. Volume III provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are referenced by a TEDS codenumber in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II

    Background The aim of this study was to establish the reference intervals (RIs) of total bilirubin (TBIL), alanine aminotransferase (ALT), aspartate transaminase (AST), and creatinine (CREA) for apparently healthy elderly (Han ethnicity) in Shuyang, China. Material/Methods A total of 54 912 blood specimens from elderly residents age 65–104 years were collected by standard procedures in Shuyang county of Jiangsu province. TBIL, ALT, AST, and CREA for each participant were determined by automatic biochemical analyzer. Distribution and differences of TBIL, ALT, AST, and CREA were analyzed and compared between the elderly of the same age of different sexes and different ages of the same sex. RIs of TBIL, ALT, AST, and CREA were compared with the current RIs. The RIs and 95% confidence intervals were calculated using nonparametric method (2.5th–97.5th percentiles) according to the guideline of the Clinical and Laboratory Standards Institute. Results RIs established for the healthy elderly include: TBIL 7.8~30.6 μmol/L for males and 7.3~26.1 μmol/L for females; ALT 8.7~47.3 U/L for males and 8.4~45.2 U/L for females; AST 15.7~46.9 U/L for males and 15.1~46.2 U/L for females; and CREA 45.1~100.9 μmol/L for males and 38.7~85.0 μmol/L for females. Reference intervals of TBIL, ALT, AST, and CREA for male elderly were higher than those of females, and values of CREA increased with increasing age. Conclusions We have established a panel of locally relevant RIs. It is necessary to establish scientific and reasonable RIs of TBIL, ALT, AST, and CREA for the healthy elderly in our region, which will provide a reference for clinicians and inspection officers.

    Technologies to survey and decontaminate wide-area contamination and process the subsequent radioactive waste have been developed and implemented following the Chernobyl nuclear power plant release and the breach of a radiological source resulting in contamination in Goiania, Brazil. These civilian examples of radioactive material releases provided some of the first examples of urban radiological remediation. Many emerging technologies have recently been developed and demonstrated in Japan following the release of radioactive cesium isotopes (Cs-134 and Cs-137) from the Fukushima Dai-ichi nuclear power plant in 2011. Information on technologies reported by several Japanese government agencies, such as the Japan Atomic Energy Agency (JAEA), the Ministry of the Environment (MOE) and the National Institute for Environmental Science (NIES), together with academic institutions and industry are summarized and compared to recently developed, deployed and available technologies in the United States. The technologies and techniques presented in this report may be deployed in response to a wide area contamination event in the United States. In some cases, additional research and testing is needed to adequately validate the technology effectiveness over wide areas. Survey techniques can be deployed on the ground or from the air, allowing a range of coverage rates and sensitivities. Survey technologies also include those useful in measuring decontamination progress and mapping contamination. Decontamination technologies and techniques range from non-destructive (e.g., high pressure washing) and minimally destructive (plowing), to fully destructive (surface removal or demolition). Waste minimization techniques can greatly impact the long-term environmental consequences and cost following remediation efforts. Recommendations on technical improvements to address technology gaps are presented together with observations on remediation in Japan.

    A liver biopsy is necessary to grade and stage chronic hepatitis C virus (HCV) infection. In a previous study of patients with nonalcoholic liver disease, an aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio >1 suggested cirrhosis. We sought to examine the value of the AST/ALT ratio in distinguishing cirrhotic patients with chronic HCV infection from noncirrhotic patients and to correlate the ratio with the grade and stage of hepatitis and other biochemical indices. We retrospectively studied 139 patients with chronic HCV infection. Routine biochemical indices were determined, and the histological grade of necroinflammatory activity and the stage of fibrosis of the liver biopsy specimens were scored. The mean AST/ALT ratio in the cirrhotic patients (n = 47) was higher than in the noncirrhotic patients (n = 92) (1.06 +/- 0.06 vs 0.60 +/- 0.09; p or =1 had 100% specificity and positive predictive value in distinguishing cirrhotic from noncirrhotic patients, with a 53.2% sensitivity and 80.7% negative predictive value. The ratio correlated positively with the stage of fibrosis but not with the grade of activity or other biochemical indices. Of the cirrhotic patients, 17% had no clinical or biochemical features suggestive of chronic liver disease except for an AST/ALT ratio > or =1. The AST/ALT ratio is a dependable marker of fibrosis stage and cirrhosis in patients with chronic HCV infection.

    A non-invasive, simple and non-expensive test to predict cirrhosis would be highly desirable. The aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio has been proven to be such an indicator of cirrhosis in alcoholic liver disease, hepatitis C. To test whether the AST/ALT ratio is a marker of cirrhosis also in patients with primary biliary cirrhosis (PBC). The study consisted of 160 patients. In 126 patients, we had clinical and laboratory data at the time of diagnosis and follow-up with outcome: liver-related death, liver transplantation and survival. In 121 patients, we had laboratory data and liver histology. We found that the AST/ALT ratio was significantly higher in cirrhotic patients than in non-cirrhotic patients. A high AST/ALT ratio was significantly associated with esophageal varices and ascites. In a multivariate analysis, bilirubin and ALP were predictors of poor prognosis. The AST/ALT ratio seems to be of clinical value as a hint to the diagnosis of cirrhosis in patients with PBC but not as a prognostic factor.

    AST-120 (kremezin; Kureha Chemical, Tokyo, Japan) is an oral spherical carbonaceous adsorbent, which was approved for clinical use in Japanese chronic kidney disease (CKD) patients in 1991. It adsorbs indole, the precursor of indoxyl sulfate, in the intestines and prevents indoxyl sulfate production. Indoxyl sulfate, initially identified as a major uremic toxin that causes uremic symptoms, contributes to CKD progression. Since AST-120 decreases serum indoxyl sulfate in a dose-dependent manner, multicenter prospective trials have been conducted in Japan in the 1980s; these trials were mostly in favor of the efficacy of AST-120 in delaying the initiation of dialysis in patients with advanced stage CKD. Many animal studies support the effects of AST-120 on renal outcomes as well as on cardiovascular complications. However, there are yet no reports that unequivocally demonstrate the improvement of hard renal endpoints and/or cardiovascular endpoints. This commentary briefly reviews the major outcomes of the recent clinical trials on AST-120. © 2016 S. Karger AG, Basel.

  4. Technology strategy for enhanced recovery; Technology Target Areas; TTA3 - enhanced recovery

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    The Norwegian Continental Shelf (NCS) is facing new challenges in reserve replacement and improved recovery in order to maintain the overall oil production rate from the area. A new target for an increase in oil reserves of 800 million Sm3 of oil (5 billion barrels) by year 2015 has been set by NPD. This is an ambitious goal considering several of the large fields are on a steep decline, and most of the recent discoveries are relatively small. A significant part of these increased reserves will have to come from fields currently on production, from reservoir areas that have been partly or fully swept, and it is therefore evident that Enhanced Oil Recovery (EOR) methods have to play a key role in achieving this target. EOR methods can be divided into gas based EOR methods and water based EOR methods. Thermal methods are not considered applicable on the NCS due to the relatively light oils present, and the depth of the reservoirs. Gas Based EOR; Water Based EOR; CO{sub 2} injection; Surfactants; Air injection; Polymer; Nitrogen injection; Alkaline; Flue gas injection; Polymer gels; WAG; MEOR; FAWAG. The former OG21 strategy document gave high priority to Water Alternating Gas (WAG) methods and CO{sub 2} injection for enhanced recovery. A lot of research and development and evaluation projects on CO{sub 2} injection were launched and are on-going, most of these are being CO{sub 2} WAG studies. The main challenge now in order to realize CO{sub 2} injection on the NCS is on CO{sub 2} availability and transport. It is also believed that increasing gas prices will limit the availability of hydrocarbon gas for injection purposes in the future. There is, however, a clear need for developing alternative cost efficient EOR methods that can improve the sweep efficiency significantly. Since a majority of the fields on the NCS are being produced under water flooding (or WAG), methods that can improve the water flooding efficiency by chemical additives are of special interest and

    To perform the translation and cultural adaptation of the Aguado Syntax Test (AST) into Brazilian Portuguese considering the linguistic and cultural reality of the language. The AST assesses the early morphosyntactic development in children aged 3 to 7 in terms of understanding and expression of various types of structures such as sentences, pronouns, verbal voices, comparisons, prepositions and verbal desinence as to number, mode and tense. The process of translation and cultural adaptation followed four steps: 1) preparation of two translations; 2) synthesis of consensual translations; 3) backtranslation; and 4) verification of equivalence between the initial translations and backtranslations that resulted in the final translated version. The whole process of translation and cultural adaptation revealed the presence of equivalence and reconciliation of the translated items and an almost complete semantic equivalence between the two translations and the absence of consistent translation difficulties. The AST was translated and culturally adapted into Brazilian Portuguese, constituting the first step towards validation and standardization of the test.

    Antarctic Survey Telescopes (AST3) are designed to be fully robotic telescopes at Dome A, Antarctica, which aim for highly efficient time-domain sky surveys as well as rapid response to special transient events (e.g., gamma-ray bursts, near-Earth asteroids, supernovae, etc.). Unlike traditional observations, a well-designed real-time survey scheduler is needed in order to implement an automatic survey in a very efficient, reliable and flexible way for the unattended telescopes. We present a study of the survey strategy for AST3 and implementation of its survey scheduler, which is also useful for other survey projects.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Volume III (this volume) provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are reference by a TEDS code number in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II.

    2012-09-01

    The COordinate Rotate DIgital Computer (CORDIC) algorithm is a well known versatile approach and is widely applied in today's SoCs for especially but not restricted to digital communications. Dedicated CORDIC blocks can be implemented in deep sub-micron CMOS technologies at very low area and energy costs and are attractive to be used as hardware accelerators for Application Specific Instruction Processors (ASIPs). Thereby, overcoming the well known energy vs. flexibility conflict. Optimizing Global Navigation Satellite System (GNSS) receivers to reduce the hardware complexity is an important research topic at present. In such receivers CORDIC accelerators can be used for digital baseband processing (fixed-point) and in Position-Velocity-Time estimation (floating-point). A micro architecture well suited to such applications is presented. This architecture is parameterized according to the wordlengths as well as the number of iterations and can be easily extended for floating point data format. Moreover, area can be traded for throughput by partially or even fully unrolling the iterations, whereby the degree of pipelining is organized with one CORDIC iteration per cycle. From the architectural description, the macro layout can be generated fully automatically using an in-house datapath generator tool. Since the adders and shifters play an important role in optimizing the CORDIC block, they must be carefully optimized for high area and energy efficiency in the underlying technology. So, for this purpose carry-select adders and logarithmic shifters have been chosen. Device dimensioning was automatically optimized with respect to dynamic and static power, area and performance using the in-house tool. The fully sequential CORDIC block for fixed-point digital baseband processing features a wordlength of 16 bits, requires 5232 transistors, which is implemented in a 40-nm CMOS technology and occupies a silicon area of 1560 μm2 only.

    Aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase-to-alanine aminotransferase (AST/ALT) ratio, platelet count, AST, albumin, bilirubin and alkaline phosphatase were retrospectively evaluated for the prediction of advanced liver fibrosis and cirrhosis in patients with resectable hepatocellular carcinoma in this study. In total, the 97 selected patients consisted of 9 (9.3%) patients with non-B, non-C chronic hepatitis, 48 (49.5%) patients with chronic hepatitis B (CHB) and 40 (41.2%) patients with chronic hepatitis C (CHC). The APRI, but not AST/ALT or other serum markers, showed a significant correlation with advanced liver fibrosis and cirrhosis (p<0.05). The area under receiver operating characteristic curves (AUROC) for predicting advanced fibrosis was 0.69 in CHB patients and 0.87 in CHC patients, whereas AUROC for predicting cirrhosis was 0.75 in CHB patients and 0.84 in CHC patients. In addition, the sensitivity and specificity of APRI were greater than 80% for predicting advanced fibrosis and cirrhosis in the CHC patients. APRI is a simple and non-invasive biochemical marker of liver fibrosis and cirrhosis, particularly in CHC patients. APRI potentially could be used to decrease the number of liver biopsies.

    A novel Plasma Enhanced Chemical Vapor Deposition method for synthesis of amorphous AsxTe100-x (31 ≤ x ≤ 49) films is demonstrated. The innovative process has been developed in a non-equilibrium low-temperature argon plasma under reduced pressure, employing for the first time volatile As and Te as precursors. Utilization of inorganic precursors, in contrast to the typically used in CVD metal-organic precursors, has given us the chance to achieve ≿halcogenide As-Te films of very high quality and purity. Phase and structural evolution of the As-Te system, based on equilibrium coexistence of two phases (AsTe and As2Te3) has been studied. The dependence of structure and optical bandgap of the chalcogenide materials on their composition was established. The newly developed process is cost-effective and enables deposition of As-Te films with a thickness ranging from 10 nm to 10 μm, the latter is highly desireable for one-mode planar waveguides applications and in other components of integral optics.

    Twenty-four nursing college students aged 16 and 17 years were selected as research subjects and divided into two groups. Group A comprised 12 individuals who were trained for short distance running (5km/day) over a four-week period, while group B was trained for middle distance running (7km/day) during the same period. Blood AST (aspartate aminotransferase), ALT (alanine aminotransferase) and lactate were performed at rest (before training) and after exercise every week. After both short and middle distance exercise training, the lactate values after 1-3 week(s) training period were persistently higher than those before training and the differences between then are significant. However, the lactate value after 4 weeks training period is lower than that after the third week training. There are significant differences between the AST values after 1-4 week(s) training period and those before exercise in short distance exercise training. There are no significant differences between the AST values after training and those before exercise in middle distance exercise training. The ALT values after 1-4 week(s) training period were lower than those before exercise in short and middle distance exercise training. In conclusion, after 4 weeks training, the lactate and AST values can't reduce to those before training in middle distance exercise training, and the lactate value in short distance exercise training is the same as former. Further investigation is needed.

  2. Polymer and Concentrator Photovoltaic Technologies - Energy Return Factors and Area Efficiency

    2006-12-20

    Market diffusion of flat plate crystalline silicon photovoltaic (PV) technology has been induced by economical support schemes and has lead to reduced cost per produced kWh electricity. For further market penetration of the PV technology, a continued reduction of production cost is required. Two alternative approaches to achieve this are using less expensive materials or changing the active materials. The technologies of concentrator PV (CPV) systems and polymer PV (PPV) devices represent these two strategies. The potential energy performance of these technologies is studied in terms of the process primary energy requirements for manufacturing, how many times this energy is paid back during its lifetime and as the required land area for electricity generation. The study is an energy analysis incorporating the inherent uncertainties in technology development. Uncertainties are identified in data acquisition, in design choices, as induced by development and improvement, in performance and by different application scenarios. The future technology alternatives are defined in different ways for CPV and PPV. CPV parameters are derived from existing products and ideas for improvements and PPV parameters from the directions of research. This study shows that the invested energy in future CPV and PPV is potentially paid back up to about 90 and 170 times, respectively, under Arizona (CPV) and average European (PPV) solar irradiation conditions. However the result is highly dependent on configuration, inventory data and device performance. Thus, for certain design alternatives, data and performance, PPV production energy is far from paid back during its lifetime. For CPV the energy return factor is decreased to about 13 in the least beneficial case. Area efficiency is studied as the land area requirements for producing a net output electricity of 1 MWh during 25 years. With device efficiencies from 1 to 5 per cent and lifetimes from 1 to 5 years a PPV device requires from 2

    High levels of liver enzymes GGT, ALT and AST are predictive of disease and all-cause mortality and can reflect liver injury, fatty liver and/or oxidative stress. Variation in GGT, ALT and AST levels is heritable. Moderation of the heritability of these liver enzymes by age and sex has not often been explored, and it is not clear to what extent non-additive genetic and shared environmental factors may play a role. To examine the genetic architecture of GGT, ALT and AST, plasma levels were assessed in a large sample of twins, their siblings, parents and spouses (N = 8,371; age range 18-90). For GGT and ALT, but not for AST, genetic structural equation modeling showed evidence for quantitative sex differences in the genetic architecture. There was no evidence for qualitative sex differences, i.e. the same genes were expressed in males and females. Both additive and non-additive genetic factors were important for GGT in females (total heritability h(2) 60 %) and AST in both sexes (total h(2) 43 %). The heritability of GGT in males and ALT for both sexes was due to additive effects only (GGT males 30 %; ALT males 40 %, females 22 %). Evidence emerged for shared environmental factors influencing GGT in the male offspring generation (variance explained 28 %). Thus, the same genes influence liver enzyme levels across sex and age, but their relative contribution to the variation in GGT and ALT differs in males and females and for GGT across age. Given adequate sample sizes these results suggest that genome-wide association studies may result in the detection of new susceptibility loci for liver enzyme levels when pooling results over sex and age.

    The current child-specific reference intervals (RIs) are inadequate or even unavailable for many analyses in China. Many of the RIs used in Chinese laboratories were derived from Chinese adult standards or from foreign studies. The aim of this study was to establish specific RIs for alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea (UR), creatinine (Cr) and uric acid (UA) for apparently healthy Chinese adolescents. Overall, 1682 apparently healthy adolescents were enrolled. Serum ALT, AST, UR, Cr and UA were measured by an ARCHITECT C-8000 automated chemistry analyzer. The 2.5th and 97.5th percentile RIs were determined using non-parametric methods. The established reference intervals for ALT, AST, UR, CR and UA were 7.5-42.8 U/L, 12.8-40.2 U/L, 3.12-6.38 mmol/L, 42.7-91.2 μmol/L, and 180.2-409.6 μmol/L in boys and 6.5-32.8 U/L, 10.4-32.5 U/L, 3.05-6.47 mmol/L, 40.2-88.8 μmol/L and 176.5-394.0 μmol/L in girls, respectively. The median and upper and lower limits for the RIs of ALT, AST, Cr and UA were higher in boys than they were in girls (P ALT, AST, UR, Cr and UA that are defined specifically for Chinese adolescents and are appropriate for universal use among Chinese laboratories.

It contributes 13 % to the value added in agriculture and 2.6 % to the GDP. The agrarian economy of Pakistan is continuously under stress due to the low yield of almost all the crops and constrained with many problem. One of the most important issues of agriculture is water shortage which is increasing day by day and is a major challenge now a days. Therefore, water saving becomes the utmost need of the hour. The national research system is now putting their focus and efforts to manage the precious water through various modern/latest water saving models to draw some solid method of irrigation with less wastage. Raised bed planting method is also one of the modern methods of planting crop with significant water saving. The study was planned and conducted by the Social Sciences Research Institute, Faisalabad in 2011-12 to assess the determinants of the adoption of the raised bed technology for wheat crop in irrigated Punjab, Pakistan. The study was conducted at three sites of the districts Faisalabad and Toba Tek Singh where the Water Management Research Institute, University of Faisalabad promoted the raised bed technology for wheat crop. A sample of 63 farmers was interviewed in detail to understand the whole system and the factors contributing to the adoption of the technology. The study revealed that adopters typically have a more favorable resource base and tend to variously outperform non-adopters. More access to education and other social indicators increases the chances to adopt new technologies by the farming community. However, the small farmers can also be benefited with the technology with proper education regarding the technology in the area with good social mobilization for the conservation of scarce and valuable farm resources.

    Resources in medical education are not evenly distributed and access to education can be more problematic in rural areas. Similar to telemedicine's positive influence on health care access, advances in information and communications technologies (ICTs) increase opportunities for medical education. This paper provides a descriptive overview of the use of ICTs in medical education and suggests a conceptual model for reviewing ICT use in medical education, describes specific ICTs and educational interventions, and discusses opportunities and challenges of ICT use, especially in rural areas. The literature review included technology and medical education, 1996-2005. Using an educational model as a framework, the uses of ICTs in medical education are, very generally, to link learners, instructors, specific course materials and/or information resources in various ways. ICTs range from the simple (telephone, audio-conferencing) to the sophisticated (virtual environments, learning repositories) and can increase access to medical education and enhance learning and collaboration for learners at all levels and for institutions. While ICTs are being used and offer further potential for medical education enhancement, challenges exist, especially for rural areas. These are technological (e.g., overcoming barriers like cost, maintenance, access to telecommunications infrastructure), educational (using ICTs to best meet learners' educational priorities, integrating ICTs into educational programs) and social (sensitivity to remote needs, resources, cultures). Finally, there is need for more rigorous research to more clearly identify advantages and disadvantages of specific uses of ICTs in medical education.

    Full Text Available The oral adsorbent AST-120 has the potential to delay dialysis initiation and improve survival of patients on dialysis. We evaluated the effect of AST-120 on dialysis initiation and its potential to improve survival in patients with chronic kidney disease. The present retrospective pair-matched study included 560 patients, grouped according to whether or not they received AST-120 before dialysis (AST-120 and non-AST-120 groups. The cumulative dialysis initiation free rate and survival rate were compared by the Kaplan-Meier method. Multivariate analysis was used to determine the impact of AST-120 on dialysis initiation. Our results showed significant differences in the 12- and 24-month dialysis initiation free rate (P<0.001, although no significant difference was observed in the survival rate between the two groups. In conclusion, AST-120 delays dialysis initiation in chronic kidney disease (CKD patients but has no effect on survival. AST-120 is an effective therapy for delaying the progression of CKD.

    The Mixed Waste Focus Area (MWFA) is currently supporting the development and demonstration of several alternative oxidation technology (AOT) processes for treatment of combustible mixed low-level wastes. The impetus for this support derives from regulatory and political hurdles frequently encountered by traditional thermal techniques, primarily incinerators. AOTs have been defined as technologies that destroy organic material without using open-flame reactions. Whether thermal or nonthermal, the processes have the potential advantages of relatively low-volume gaseous emissions, generation of few or no dioxin/furan compounds, and operation at low enough temperatures that metals (except mercury) and most radionuclides are not volatilized. Technology development and demonstration are needed to confirm and realize the potential of AOTs and to compare them on an equal basis with their fully demonstrated thermal counterparts. AOTs include both thermal and nonthermal processes that oxidize organic wastes but operate under significantly different physical and chemical conditions than incinerators. Nonthermal processes currently being studied include Delphi DETOX and acid digestion at the Savannah River Site, and direct chemical oxidation at Lawrence Livermore National Laboratory. All three technologies are at advanced stages of development or are entering the demonstration phase. Nonflame thermal processes include catalytic chemical oxidation, which is being developed and deployed at Lawrence Berkeley National Laboratory, and team reforming, a commercial process being supported by Department of Energy. Related technologies include two low-flow, secondary oxidation processes (Phoenix and Thermatrix units) that have been tested at MSE, Inc., in Butte, Montana. Although testing is complete on some AOT technologies, most require additional support to complete some or all of the identified development objectives.

    Full Text Available A lot of research works have been made concerning highway service area or solar technology and acquired great achievements. However, unfortunately, few works have been made combining the two topics together of highway service areas and solar energy saving to make a systemic research on solar technology application for highway service area. In this paper, taking West Lushan highway low-carbon service area in Jiangxi Province of China as the case study, the advantages, technical principles, and application methods of solar energy technology for highway service area including solar photoelectric technology and solar water heating technology were discussed based on the analysis of characteristics of highway low-carbon service area; the system types, operation mode, and installing tilt angle of the two kinds of solar systems suitable for highway service areas were confirmed. It was proved that the reduction of the cost by electricity savings of solar system was huge. Taking the investment of the solar systems into account, the payback period of solar photoelectric systems and solar water heating systems was calculated. The economic effect of the solar systems in West Lushan highway service area during the effective operation periods was also calculated and proved very considerable.

    Water scarcity is threatening social and economic growth in rural areas of developing countries. There are potential markets for water purification technologies in these regions. The main focus of this article is to evaluate the social, economic and political feasibilities of providing water purification technologies to rural areas of developing countries. The findings of this research can serve as the basis for private investors interested in entering this market. Four representative regions were selected for the study. Economic, demographic, and environmental variables of each region were collected and analyzed along with domestic markets and political information. Rural areas of the developing world are populated with poor people unable to fulfill the basic needs for clean water and sanitation. These people represent an important group of potential users. Due to economic, social, and political risks in these areas, it is difficult to build a strong case for any business or organization focusing on immediate returns on capital investment. A plausible business strategy would be to approach the water purification market as a corporate responsibility and social investing in the short term. This would allow an organization to be well positioned once the economic ability of individuals, governments, and donor agencies are better aligned.

    Precision measurements of direct and mixing-induced $C\\!P$-violating observables in neutral $B^0_s$-meson decays are amongst the most promising ways to look for signs of new physics in the flavour sector. The $C\\!P$-violating phase $\\phi_s$, which arises in the interference between the amplitudes of direct $B^0_s$-meson decay and the decay after oscillation in $b \\to q\\bar{q}s$ transitions, is particularly interesting because the Standard Model expectation for its value is both very small and precise. In this talk, an overview of the current experimental status and latest developments in this area will be presented, notably including a novel LHCb measurement of $\\phi_s$ performed for the first time ever using the $B^0_s \\to (K^+\\pi^-)(K^-\\pi^+)$ decay. This decay proceeds via a $b \\to d\\bar{d}s$ transition, which can only occur at loop level in the Standard Model, thus providing a sensitive probe for new physics.

    3D models of urban areas have found use in modern world such as navigation, cartography, urban planning visualization, construction, tourism and even in new applications of mobile navigations. With the advancement of technology there are much better solutions for mapping earth’s surface and spatial objects. 3D city model enables exploration, analysis, management tasks and presentation of a city. Urban areas consist of terrain surfaces, buildings, vegetation and other parts of city infrastructure such as city furniture. Nowadays there are a lot of different methods for collecting, processing and publishing 3D models of area of interest. LIDAR technology is one of the most effective methods for collecting data due the large amount data that can be obtained with high density and geometrical accuracy. CityGML is open standard data model for storing alphanumeric and geometry attributes of city. There are 5 levels of display (LoD0, LoD1, LoD2, LoD3, LoD4). In this study, main aim is to represent part of urban area of Novi Sad using LIDAR technology, for data collecting, and different methods for extraction of information’s using CityGML as a standard for 3D representation. By using series of programs, it is possible to process collected data, transform it to CityGML and store it in spatial database. Final product is CityGML 3D model which can display textures and colours in order to give a better insight of the cities. This paper shows results of the first three levels of display. They consist of digital terrain model and buildings with differentiated rooftops and differentiated boundary surfaces. Complete model gives us a realistic view of 3D objects.

    The US Department of Energy (DOE) faces a major challenge in cleaning up its contaminated sites throughout the United States. One major area of concern is the plumes in soil and ground water which are contaminated with a myriad of different pollutants. DOE recently organized its plume-related problems into the Plume Focus Area. The mission of the Plume Focus Area is to enhance the deployment of innovative technologies for containing and cleaning up contaminant plumes in ground water and soil at all DOE sites. Environmental cleanup priorities for soil and ground water plumes are being defined and technology users have the challenge of matching current and innovative technologies to those priorities. By involving a range of stakeholders in the selection, demonstration, and evaluation of new technologies, the deployment of these technologies can be enhanced. If new plume cleanup technologies are to be deployable, they must improve on today's baseline technologies. The Sites' Coordination Team (SCT) of the Plume Focus Area develops and supports the implementation of methods for stakeholder involvement throughout the multiple steps that define focus area activities. Site-specific teams are being formed to carry out the strategy at each site, and the teams will work through Site Technology Coordination Groups (STCGs) at each location. The SCT is responsible for identifying the site-specific stakeholder involvement teams, training the team members, preparing needed national-level guidance and strategies, helping the teams tailor a strategy for their particular site that meets the overall needs of the focus area, and facilitating inter-site coordination. The results will be used to develop national technology acceptance reports on the innovative technologies being funded and evaluated under the Plume Focus Area

    Accurate area assessment of a burn injury and its treatment according to its depth of injury are the foundation of burn treatment due to its complexity, and various techniques and methods have been employed to solve these problems for many years. As the demand of modern medicine calls for individualized and precise therapeutic measures, it is clear that the traditional diagnostic and treatment measures are insufficient. The flourishing development of three-dimensional (3D) technology seems to provide new research approaches and technical opporturities for burn surgery. A series of techniques such as 3D model, 3D scanning, and 3D printing may be promising in advancing burn surgery through basic research to achieve rational clinical applications in the future. In this paper, the applications and achievements of 3D technology in burn surgery in recent years are summarized.

    Chronic kidney disease (CKD) impairs intestinal barrier function which by allowing influx of noxious products causes systemic inflammation. We have recently shown that intestinal barrier dysfunction in CKD is due to degradation of epithelial tight junction (TJ) which is, in part, mediated by influx of urea and its conversion to ammonia by microbial urease. We hypothesized that by adsorbing urea and urea-derived ammonia, oral activated charcoal (AST-120) may ameliorate CKD-induced intestinal epithelial barrier disruption and systemic inflammation. Rats were randomized to the CKD or control groups. The CKD group was fed a chow containing 0.7% adenine for 2 weeks. They were then randomized to receive a chow with or without AST-120 (4 g/kg/day) for 2 weeks. Rats consuming regular diet served as controls. Animals were then euthanized, colons were removed and processed for Western blot and immunohistology, and plasma was used to measure endotoxin and oxidative and inflammatory markers. Compared with the controls, the untreated CKD rats showed elevated plasma endotoxin, IL-6, TNF-α, MCP-1, CINC-3, L-selectin, ICAM-1, and malondialdehyde, and depletions of colonic epithelial TJ proteins, claudin-1, occludin, and ZO1. Administration of AST-120 resulted in partial restoration of the epithelial TJ proteins and reduction in plasma endotoxin and markers of oxidative stress and inflammation. CKD animals exhibited depletion of the key protein constituents of the colonic epithelial TJ which was associated with systemic inflammation, oxidative stress and endotoxemia. Administration of AST-120 attenuated uremia-induced disruption of colonic epithelial TJ and the associated endotoxemia, oxidative stress and inflammation. Copyright © 2013 S. Karger AG, Basel.

    We show that many well-known quantum field theories emerge as representations of a single $^\\ast$-algebra. These include free quantum field theories in flat and curved space-times, lattice quantum field theories, Wightman quantum field theories, and string theories. We prove that such theories can be approximated on lattices, and we give a rigorous definition of the continuum limit of lattice quantum field theories.

    Despite on the improvements in the quality of high-rise construction areas and industrial wastewater treatment, the pollution of water bodies continues to increase. This is due to the organized and unorganized surface untreated sewage entry into the reservoirs. The qualitative analysis of some cities' surface sewage composition is carried out in the work. Based on the published literature review, the characteristic contamination present in surface wastewater was identified. The paper proposes a new technology for the treatment of surface sewage and presents the results of preliminary studies.

    Enteroviral myocarditis is often a relatively benign condition in adults. Physicians, therefore, may not always record detailed clinical and laboratory data in such patients. As such, they may not recognize viral involvement in organs beyond the heart. The purpose of this study was to examine the hepatic involvement of enteroviral peri-myocarditis and to compare the other diseases with congestive heart failure. We analyzed 18 patients (ages 15-64) who were diagnosed as having enteroviral myocarditis (n = 16) or pericarditis (n = 2). Serology was positive for coxsackie viruses in 11 patients and echoviruses in six patients. A diagnosis of hepatic involvement was made by the following laboratory data: rising levels of alanine amino transferase (ALT), aspartate amino transferase (AST) and exceeded serum ALT compared with AST levels. A ratio of ALT/AST more than 1.0 was greatly frequent in patients with peri-myocarditis (72%; 13/18) compared with acute myocardial infarction (0%; 0/10) and idiopathic dilated cardiomyopathy (3%; 3/10). In summary, hepatic involvement in the setting of acute enteroviral peri-myocarditis may be considerably more common in adults than previously suspected. The recognition of hepatic involvement in association with enteroviral peri-myocarditis may allow improvement of diagnostic sensitivity and alter approaches to treatments of acute viral myocarditis.

    This work analyzes the prevalence of TTV DNA in peripheral blood cells from patients with hepatic alterations and healthy blood donors and measures levels of sodium, potassium, urea, creatinine, phosphatase alkaline, total and direct bilirubin, gamma glutamyl transferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in certain randomly selected patients. DNA samples from 111 individuals were evaluated. They were divided into two groups, "A" (study) and "B" (control), including 54 patients with liver enzyme alterations (ALT/AST) presenting non-B-non-C hepatitis and 57 blood donors, respectively. TTV DNA was determined by nested PCR. Certain products of the second-round PCR were sequenced. Serum biochemical assay was performed and disclosed TTV in 31.48% (17/54) of patients in group A and 5.26% (3/57) in the control group B. TTV prevalence was significantly higher in patients with liver disease than in healthy donors. In group A, sodium, potassium, urea, creatinine, phosphatase alkaline, total and direct bilirubin, gamma glutamyl transferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were analyzed in certain randomly selected patients and no significant difference in biochemical levels (p>0.05) was found when TTV infected and noninfected individuals were compared. Knowledge related to TTV has rapidly increased, but many fundamental aspects remain unclear. This led us to question the role of TTV and doubt remains as to whether or not it is just a commensal virus. Further studies are necessary to confirm and extend these findings.

    1998-09-01

    Medical guidelines for interferon-alpha2a or -alpha2b (IFN-alpha) treatment of chronic hepatitis C virus (HCV) infection depend upon baseline liver histology. A better long-term response to IFN-alpha therapy correlates with less inflammation and absence of cirrhosis. It has been suggested that the presence of cirrhosis in patients with chronic hepatitis C virus infection may be predicted based on an AST/ALT ratio > or = 1. This study was designed to determine if the presence of cirrhosis can be predicted in patients with chronic HCV infection by such a ratio. Seventy-seven patients, including 23 cirrhotics, with chronic HCV infection were studied. Serum ALT, AST, and HCV-RNA levels and hepatic activity index (HAI), reflecting histologic inflammation in all liver biopsies, were assessed. AST/ALT ratios and mean ALT, AST, and HCV-RNA were determined for both cirrhotic and noncirrhotic patients. HAI was correlated with ALT, AST, and HCV-RNA levels, the latter determined by quantitative RT-PCR. The likelihood ratio (LR) and positive predictive value of an AST/ALT ratio > or = 1 for cirrhosis was 7.3 and only 77%, respectively. In cirrhotics vs noncirrhotics, there were no significant differences between mean serum ALT (149 +/- 28 vs 176 +/- 17 units/liter), AST (139 +/- 28 vs 102 +/- 8 units/liter), or HCV-RNA levels (589,160 +/- 147,053 vs 543,915 +/- 75,497 copies/ml), respectively. There was a significant, but clinically weak, correlation between serum ALT and HAI (r = 0.234), and none between HAI and either serum AST or HCV-RNA levels. Our results support the need for a liver biopsy prior to treatment of chronic HCV infection, since the AST/ALT ratio fails to predict accurately the presence of cirrhosis.

    Energy Technology Data Exchange (ETDEWEB)

    2008-07-01

    Executive summary 'Deepwater and Subsea Production Systems' has been identified as one of the eight new Technology Target Areas (TTAs) in Norway's technology strategy for the Oil and Gas sector. This TTA covers deepwater floating production systems, subsea systems (except subsea processing technologies which are addressed by TTA6) and arctic development systems (in both shallow and deepwater). The total hydrocarbon reserves worldwide, which are enabled by the technologies under this TTA exceed 400 billion boe which, itself exceeds the proven reserves of Saudi Arabia. For deepwater developments the long term technical challenge is to develop flexible and adaptive systems which are better able to cope with subsurface uncertainties e.g. compartmentalisation and provide required access to the reservoir to enable successful recovery. More specific medium term challenges relate to developing solutions for harsh environmental conditions such as those offshore Norway and to develop cost effective methods of installing subsea hardware in deep and ultra deep water without requiring expensive crane vessels. For subsea systems the challenge is to develop solutions for ultra deepwater without increasing costs, so that Norway's leading export position in this area can be maintained and strengthened. Considering developments in the arctic, Norwegian industry is already well placed through its familiarity with arctic climate, close relationship with Russia and involvement in Sakhalin II. As we move to water depth beyond about 150m use of Gravity Base Structures (GBS) becomes very expensive or non-feasible and we need to consider other solutions. Subsea-to-beach could be an attractive solution but we need to resolve challenges related to long distance tie backs, flow assurance, uneven terrain, etc. There is also a specific need to develop floating systems capable of drilling and production in an arctic environment. To address the above technical challenges the

    This paper presents a novel large-area strain sensing technology for monitoring fatigue cracks in steel bridges. The technology is based on a soft elastomeric capacitor (SEC), which serves as a flexible and large-area strain gauge. Previous experiments have verified the SEC’s capability to monitor low-cycle fatigue cracks experiencing large plastic deformation and large crack opening. Here an investigation into further extending the SEC’s capability for long-term monitoring of fatigue cracks in steel bridges subject to traffic loading, which experience smaller crack openings. It is proposed that the peak-to-peak amplitude (pk-pk amplitude) of the sensor’s capacitance measurement as the indicator of crack growth to achieve robustness against capacitance drift during long-term monitoring. Then a robust crack monitoring algorithm is developed to reliably identify the level of pk-pk amplitudes through frequency analysis, from which a crack growth index (CGI) is obtained for monitoring fatigue crack growth under various loading conditions. To generate representative fatigue cracks in a laboratory, loading protocols were designed based on constant ranges of stress intensity to limit plastic deformations at the crack tip. A series of small-scale fatigue tests were performed under the designed loading protocols with various stress intensity ratios. Test results under the realistic fatigue crack conditions demonstrated the proposed crack monitoring algorithm can generate robust CGIs which are positively correlated with crack lengths and independent from loading conditions.

    Full Text Available This article addresses the challenges of cybersecurity and ultimately the provision of a stable and resilient information-technology infrastructure for Canada and, more broadly, the world. We describe the context of current cybersecurity challenges by synthesizing key source material whose importance was informed by our own real-world experiences. Furthermore, we present a checklist of guiding principles to a unified response, complete with a set of action-oriented research topics that are linked to known operational limitations. The focus areas are used to drive the formulation of a unified and relevant research and experimental development program, thereby moving us towards a stable and resilient cyberinfrastructure. When cybersecurity is viewed as an inherently interdisciplinary problem of societal concern, we expect that fundamentally new research perspectives will emerge in direct response to domain-specific protection requirements for information-technology infrastructure. Purely technical responses to cybersecurity challenges will be inadequate because human factors are an inherent aspect of the problem. This article will interest managers and entrepreneurs. Senior management teams can assess new technical developments and product releases to fortify their current security solutions, while entrepreneurs can harness new opportunities to commercialize novel technology to solve a high-impact cybersecurity problem..

    International Nuclear Information System (INIS)

    1998-02-01

    Pipe Crawler reg-sign is a pipe surveying system for performing radiological characterization and/or free release surveys of piping systems. The technology employs a family of manually advanced, wheeled platforms, or crawlers, fitted with one or more arrays of thin Geiger Mueller (GM) detectors operated from an external power supply and data processing unit. Survey readings are taken in a step-wise fashion. A video camera and tape recording system are used for video surveys of pipe interiors prior to and during radiological surveys. Pipe Crawler reg-sign has potential advantages over the baseline and other technologies in areas of cost, durability, waste minimization, and intrusiveness. Advantages include potentially reduced cost, potential reuse of the pipe system, reduced waste volume, and the ability to manage pipes in place with minimal disturbance to facility operations. Advantages over competing technologies include potentially reduced costs and the ability to perform beta-gamma surveys that are capable of passing regulatory scrutiny for free release of piping systems

    It is of great importance to measure the lesion area in scientific research and clinical practice. The present study aims to solve barrel distortion and measure lesion area with the technology of computer visualization. With the ultimate purpose to obtain the precise lesion area, the study, based on the original endoscopy system and digital image processing technology, dealt with the correction of barrel distortion by lens adjustment, calculated the gastric ulcer area with the aid of Qt database and finally developed an image processing software--Endoscope Assistant (EAS). The results showed that the EAS was accurate in vitro. It was employed to measure the gastric ulcer area of 45 patients and the results were compared with the traditional formula method. It could be well concluded that this technology is safe, accurate and economical for measuring gastric ulcer area.

  19. Technology strategy for integrated operations and real time reservoir management; Technology Target Areas; TTA5 - Integrated operations and RTRM

    2007-07-01

    In Norway Integrated Operations (IO) is a concept which in the first phase (G1) has been used to describe how to integrate processes and people onshore and offshore using ICT solutions and facilities that improve onshore's ability to support offshore operationally. The second generation (G2) Integrated Operations aims to help operators utilize vendors' core competencies and services more efficiently. Utilizing digital services and vendor products, operators will be able to update reservoir models, drilling targets and well trajectories as wells are drilled, manage well completions remotely, optimize production from reservoir to export lines, and implement condition-based maintenance concepts. The total impact on production, recovery rates, costs and safety will be profound. When the international petroleum business moves to the Arctic region the setting is very different from what is the case on the Norwegian Continental Shelf (NCS) and new challenges will arise. The Norwegian Ministry of Environment has recently issued an Integrated Management Plan for the Barents Sea where one focus is on 'Monitoring of the Marine Environment in the North'. The Government aims to establish a new and more coordinated system for monitoring the marine ecosystems in the north. A representative group consisting of the major Operators, the Service Industry, Academia and the Authorities have developed the enclosed strategy for the OG21 Integrated Operations and Real Time Reservoir Management (IO and RTRM) Technology Target Area (TTA). Major technology and work process research and development gaps have been identified in several areas: Bandwidth down-hole to surface; Sensor development including Nano-technology; Cross discipline use of Visualisation, Simulation and model development particularly in Drilling and Reservoir management areas; Software development in terms of data handling, model updating and calculation speed; Enabling reliable and robust communications

  20. Individual differences in plasma ALT, AST and GGT: contributions of genetic and environmental factors, including alcohol consumption.

    Whitfield, J B; Martin, N G

    1985-01-01

    The causes of individuality of the plasma enzymes alanine aminotransferase (ALT; EC 2.6.1.2), aspartate aminotransferase (AST; EC 2.6.1.1) and gamma-glutamyl transferase (GGT; EC 2.3.2.2) were investigated in a study of 206 pairs of twins. Between-person variance was greater in men than women, while within-person variation was similar in both sexes. Plasma ALT and AST levels were affected by genetic factors, while GGT was affected by some environmental factor shared by co-twins. In the men, alcohol intake had a significant but small effect on all three enzyme levels, and since alcohol consumption was highly heritable, this appeared as a genetic influence on enzyme activities. The major factors involved in the observed correlations between these enzymes were a non-shared environmental factor other than alcohol affecting ALT, AST and GGT, and a genetic factor affecting only ALT and AST.

    Full Text Available Background: In recent years the ratio of aspartate aminotransferase (AST to alanine aminotransferase (ALT in patients of chronic liver disease (CLD of various origins has gained much attention. This variable is readily available, easy to interpret, and inexpensive and the clinical utility of the AST/ALT ratio in the diagnostic workup of patients with CLD is quite promising. Objective: The present study was designed to find out the link between aminotransferase (AST/ALT ratio with commonly measured biochemical parameters of liver function tests in CLD of viral origin. Materials and method: This cross sectional study was carried out in the department of Biochemistry, Sir Salimullah Medical College, Dhaka, Bangladesh. Forty four biopsy proven diagnosed subjects of chronic viral hepatitis without cirrhosis of both sex were selected purposively. With aseptic precaution 5 mL venous blood was collected from each subject and common liver function tests (serum AST, ALT, AST/ALT ratio, alkaline phosphatase, total bilirubin, serum total protein, serum albumin, serum globulin, serum albumin/globulin ratio, prothrombin time and viral serology (HBsAg, Anti HDV antibody, Anti HCV antibody were performed. Data were analyzed by SPSS version 19 for Windows. Pearson’s correlation test was done to determine association between AST/ALT with other biochemical parameters.

Pearson’s correlation test was done between AST to ALT ratio with other biochemical parameters and prothrombin time showed significant positive correlation (p <0.01. Conclusion: In our study we found significant positive correlation between AST/ALT with prothrombin time in CLD subjects without cirrhosis.

  2. Initial Results of Accelerated Stress Testing on Single-Channel and Multichannel Drivers: Solid-State Lighting Technology Area

    None

    2018-02-28

    This report is the first in a series of studies on accelerated stress testing (AST) of drivers used for SSL luminaires, such as downlights, troffers, and streetlights. A representative group of two-stage commercial driver products was exposed to an AST environment consisting of 75°C and 75% relative humidity (7575). These drivers were a mix of single-channel drivers (i.e., a single output current for one LED primary) and multichannel drivers (i.e., separate output currents for multiple LED primaries). This AST environment was chosen because previous testing on downlights with integrated drivers demonstrated that 38% of the sample population failed in less than 2,500 hours of testing using this method. In addition to AST test results, the performance of an SSL downlight product incorporating an integrated, multichannel driver during extended room temperature operational life (RTOL) testing is also reported. A battery of measurements was used to evaluate these products during accelerated testing, including full electrical characterization (i.e., power consumption, PF, total harmonic distortion [THD], and inrush current) and photometric characterization of external LED loads attached to the drivers (i.e., flicker performance and lumen maintenance).

    Energy Technology Data Exchange (ETDEWEB)

    2008-07-01

    In future, research within exploration and reservoir characterization will play an even more important role for Norway since resources are decreasing and new challenges like deep sea, harsh environment and last but not least environmental issues have to be considered. There are two major fields which have to be addressed within exploration and reservoir characterization: First, replacement of reserves by new discoveries and ultimate field recoveries in mature basins at the Norwegian Continental shelf, e.g. at the Halten Terrace has to be addressed. A wealth of data exists in the more mature areas. Interdisciplinary integration is a key feature of reservoir characterization, where available data and specialist knowledge need to be combined into a consistent reservoir description. A systematic approach for handling both uncertainties in data sources and uncertainties in basic models is needed. Fast simulation techniques are necessary to generate models spanning the event space, covering both underground based and model-based uncertainties. Second, exploration in frontier areas like the Barents Sea region and the deeper Voering Basin has to be addressed. The scarcity of wells in these frontier areas leads to uncertainties in the geological understanding. Basin- and depositional modelling are essential for predicting where source rocks and reservoir rocks are deposited, and if, when and which hydrocarbons are generated and trapped. Predictive models and improved process understanding is therefore crucial to meet these issues. Especially the challenges related to the salt deposits e.g. sub-salt/sub-basalt reservoir definitions in the Nordkapp Basin demands up-front research and technology developments. TTA2 stresses the need to focus on the development of new talents. We also see a strong need to push cooperation as far as possible in the present competitive environment. Projects that may require a substantial financial commitment have been identified. The following

    One method proposed for the cleanup of the D-Area Oil Seepage Basin was in situ bioremediation (bioventing), involving the introduction of air and gaseous nutrients to stimulate contaminant degradation by naturally occurring microorganisms. To test the feasibility of this approach, a bioventing system was installed at the site for use in optimization testing by the Environmental Biotechnology Section of the Savannah River Technology Center. During the interim action, two horizontal wells for a bioventing remediation system were installed eight feet below average basin grade. Nine piezometers were also installed. In September of 1996, a generator, regenerative blower, gas cylinder station, and associated piping and nutrient injection equipment were installed at the site and testing was begun. After baseline characterization of microbial activity and contaminant degradation at the site was completed, four injection campaigns were carried out. These consisted of (1) air alone, (2) air plus triethylphosphate (TEP), (3) air plus nitrous oxide, and (4) air plus methane. This report describes results of these tests, together with conclusions and recommendations for further remediation of the site. Natural biodegradation rates are high. Oxygen, carbon dioxide, and methane levels in soil gas indicate substantial levels of baseline microbial activity. Oxygen is used by indigenous microbes for biodegradation of organics via respiration and hence is depleted in the soil gas and water from areas with high contamination. Carbon dioxide is elevated in contaminated areas. High concentrations of methane, which is produced by microbes via fermentation once the oxygen has been depleted, are found at the most contaminated areas of this site. Groundwater measurements also indicated that substantial levels of natural contaminant biodegradation occurred prior to air injection

  8. Near-Field Coupling Communication Technology For Human-Area Networking

    Directory of Open Access Journals (Sweden)

    Ryoji Nagai

    2012-12-01

    Full Text Available We propose a human-area networking technology that uses the surface of the human body as a data transmission path and uses near-field coupling TRXs. This technology aims to achieve a "touch and connect" form of communication and a new concept of "touch the world" by using a quasi-electrostatic field signal that propagates along the surface of the human body. This paper explains the principles underlying near-field coupling communication. Special attention has been paid to common-mode noise since our communication system is strongly susceptible to this. We designed and made a common-mode choke coil and a transformer to act as common-mode noise filters to suppress common-mode noise. Moreover, we describe how we evaluated the quality of communication using a phantom model with the same electrical properties as the human body and present the experimental results for the packet error rate (PER as a function of the signal to noise ratio (SNR both with the common-mode choke coil or the transformer and without them. Finally, we found that our system achieved a PER of less than 10-2 in general office rooms using raised floors, which corresponded to the quality of communication demanded by communication services in ordinary office spaces.

    Intima media thickness (IMT) and stiffness of the carotid arteries is related to coronary artery disease, and chronic renal failure patients are at high risk for such diseases. An oral adsorbent, AST-120 (Kremezin; Kureha Chemical Industry, Tokyo, Japan), can delay the progression of chronic renal failure in undialyzed uremic patients. The aim of the present study was to determine whether AST-120 affects carotid artery IMT and pulse wave velocity (PWV) in patients with chronic renal failure not undergoing dialysis. Fifty patients with non-diabetic chronic renal failure were randomly divided into two groups: 30 patients (18 men and 12 women; mean age 53.5 years; mean serum creatinine 3.2 mg/dl) who were given AST-120 (6.0 g/day) and 20 patients (12 men and 8 women; mean age 52.0 years; mean serum creatinine 3.5 mg/dl) who were not given AST-120. Thirty healthy age-matched subjects (18 men and 12 women; mean age 51.5 years; mean serum creatinine 0.9 mg/dl) were also included. The treatment period was 24 months. IMT and arterial stiffness were measured before and after treatment. The slope of the reciprocal serum creatinine concentration over time became significantly less steep in the AST-120 group than in the non-AST-120 group (p < 0.001). Before treatment, carotid artery IMT differed little between the AST-120 group (0.90 +/- 0.22 mm) and the non-AST-120 group (0.88 +/- 0.20 mm). IMT in these two groups was significantly greater than IMT in the control group (0.64 +/- 0.14 mm) (p < 0.01). Carotid IMT in the AST-120 group decreased slightly but not significantly to 0.84 +/- 0.20 mm after 12 months and then significantly after 24 months to 0.78 +/- 0.18 mm (p < 0.05). Carotid IMT in the non-AST group showed little change throughout the experimental period. PWV differed little between the AST-120 group (1,980 +/- 330 cm/s) and the non-AST group (1,940 +/- 360 cm/s) before treatment. PWV values in these two groups were significantly greater than PWV in the control

    To investigate the protective effects of polydatin on sepsis-induced acute liver injury (ALI) in mice, and to preliminarily study its mechanisms. The sepsis model was established using cecal ligation and puncture (CLP).A sham-operation control group was also set up. Polydatin (50, 100, and 300 mg/kg, respectively) was administrated to mice 1 h before CLP. The survival and liver injury were evaluated subsequently per 6 h after CLP. The survived mice were scarified 24 h later. The serum and the liver tissue sample were collected. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected by colorimetric method. The content of tumor necrosis factor-alpha (TNF-alpha) was assayed by ELISA. The cyclooxygenase-2 (COX-2) expression in the liver tissue was detected by Western blot. The pathological changes of the hepatic tissue were analyzed by hematoxylin and eosin stain. The mortality of mice reached as high as 50% at 24 h after CLP. The biochemical indices and the pathological changes of the liver tissue showed obvious lesion. The success rate of modeling was 90%. Compared with the sham-operation control group, the serum ALT,AST activity, the TNF-alpha content, and the hepatic COX-2 protein expression markedly increased in the CLP group (P < 0.01). Polydatin improved the sepsis-induced mortality dose-dependently, inhibited increased ALT, AST activity and TNF-alpha, decreased the hepatic COX-2 protein expression, and attenuated the pathological injury of the liver (P < 0.05). Polydatin could effectively protect sepsis-induced ALI, which might be achieved possibly through inhibiting serum TNF-alpha production and hepatic COX-2 expression.

    Studies on theoretical simulation of the dynamic behaviour of the AST-500 type reactor primary coolant system are summarized. The first version of a dynamic model in the form of the DYNAST code is described. The DYNAST code is based on a one-dimensional description of the primary coolant circuit including core, draught stack, and intermediate heat exchanger, a vapour dome model, and the point model of neutron kinetics. With the aid of the steady-state computational part of the DYNAST code, studies have been performed on different steady-state operating conditions. Furthermore, some methodological investigations on generalization and improvement of the dynamic model are considered and results presented. (author)

    Full Text Available The quarrying industry is changing the local landscape, forming deep open pits and spoil heaps in close proximity to them, especially lignite mines. The impact can include toxic soil material (low pH, heavy metals, oxidations etc. which is the basis for further reclamation and afforestation. Forests that stand on spoil heaps have very different growth conditions because of the relief (slope, aspect, wind and rainfall shadows, supply of solar energy, etc. and type of soil that is deposited. Airborne laser scanning (ALS technology deliver point clouds (XYZ and derivatives as raster height models (DTM, DSM, nDSM=CHM which allow the reception of selected 2D and 3D forest parameters (e.g. height, base of the crown, cover, density, volume, biomass, etc. The automation of ALS point cloud processing and integrating the results into GIS helps forest managers to take appropriate decisions on silvicultural treatments in areas with failed plantations (toxic soil, droughts on south-facing slopes; landslides, etc. or as regular maintenance. The ISOK country-wide project ongoing in Poland will soon deliver ALS point cloud data which can be successfully used for the monitoring and management of many thousands of hectares of destroyed post-industrial areas which according to the law, have to be afforested and transferred back to the State Forest.

    Nielsen, Curtis P.

    The purpose of this study was to investigate the transfer of geospatial technology knowledge and skill presented in a social sciences course context to other core areas of the curriculum. Specifically, this study explored the transfer of geospatial technology knowledge and skill to the STEM-related core areas of science and mathematics among ninth-grade students. Haskell's (2001) research on "levels of transfer" provided the theoretical framework for this study, which sought to demonstrate the experimental group's higher ability to transfer geospatial skills, higher mean assignment scores, higher post-test scores, higher geospatial skill application and deeper levels of transfer application than the control group. The participants of the study consisted of thirty ninth-graders enrolled in U.S. History, Earth Science and Integrated Mathematics 1 courses. The primary investigator of this study had no previous classroom experiences with this group of students. The participants who were enrolled in the school's existing two-section class configuration were assigned to experimental and control groups. The experimental group had ready access to Macintosh MacBook laptop computers, and the control group had ready access to Macintosh iPads. All participants in U.S. History received instruction with and were required to use ArcGIS Explorer Online during a Westward Expansion project. All participants were given the ArcGIS Explorer Online content assessment following the completion of the U.S. History project. Once the project in U.S. History was completed, Earth Science and Integrated Mathematics 1 began units of instruction beginning with a multiple-choice content pre-test created by the classroom teachers. Experimental participants received the same unit of instruction without the use or influence of ArcGIS Explorer Online. At the end of the Earth Science and Integrated Math 1 units, the same multiple-choice test was administered as the content post-test. Following the

    AST3-1 is the second-generation wide-field optical photometric telescope dedicated to time-domain astronomy at Dome A, Antarctica. Here, we present the results of an i -band images survey from AST3-1 toward one Galactic disk field. Based on time-series photometry of 92,583 stars, 560 variable stars were detected with i magnitude ≤16.5 mag during eight days of observations; 339 of these are previously unknown variables. We tentatively classify the 560 variables as 285 eclipsing binaries (EW, EB, and EA), 27 pulsating variable stars ( δ Scuti, γ Doradus, δ Cephei variable, and RR Lyrae stars), and 248 other types of variables (unclassified periodic, multiperiodic, and aperiodic variable stars). Of the eclipsing binaries, 34 show O’Connell effects. One of the aperiodic variables shows a plateau light curve and another variable shows a secondary maximum after peak brightness. We also detected a complex binary system with an RS CVn-like light-curve morphology; this object is being followed-up spectroscopically using the Gemini South telescope.

    Full Text Available The methods of decontamination of radionuclides from soils are considered. The literature focuses on fixing radionuclides in soils and creating geochemical barriers that it is prevent the spread of pollution. The main disadvantage of these methods is exclude the possibility of building a territory. It is need to clean up the area to the sanitary and hygienic requirements for further use and then it is desirable to fix the residual activity. Carried out an analysis of forms of radionuclides fixation in soils and mechanics of this fixation, therewith revealed that Cs-137 fixed more strongly on mineral component of soil, than Sr-90, which is mainly in the acid-soluble and exchangeable form, and, as a consequence, passes into the liquid phase during soil deactivation more easily. Contaminated soil deactivation in the urbanized territory is possible by washing it by ferric chloride solution at a concentration 0.02-0.05 M and with an equimolar addition of an ammonium chloride. Therewith most efficient methods, which used in-situ conditions, are heap and convection leaching technologies with treatment degree, which not less than 80%. At the same time, the most efficient methods which used in-situ conditions are heap and the convection leaching. The hardware-technological scheme of a convection leaching is presented. Noted that ammonium salts additions slightly rising coefficient of treatment from Sr-90. Because ammonium salts aren’t expensive, their additions allow to obtain significant economic benefits due to decreasing of ferric chloride consumption, which is more valuable, and waste water volume reduction.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II (this volume) describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Specific INEL problem areas/contaminants are identified along with technology solutions, the status of the technologies, precise science and technology needs, and implementation requirements. Volume III provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are referenced by a TEDS codenumber in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II.

    Aerial multispectral scanner imagery was collected of the Rocky Flats Environmental Technology Site in Golden, Colorado, on June 3, 5, 6, and 7, 1994, using a Daedalus AADS1268 multispectral scanner and coincident aerial color and color infrared photography. Flight altitudes were 4,500 feet (1372 meters) above ground level to match prior 1989 survey data; 2,000 feet (609 meters) above ground level for sitewide vegetation mapping; and 1,000 feet (304 meters) above ground level for selected areas of special interest. A multispectral survey was initiated to improve the existing vegetation classification map, to identify seeps and springs, and to generate ARC/INFO Geographic Information System compatible coverages of the vegetation and wetlands for the entire site including the buffer zone. The multispectral scanner imagery and coincident aerial photography were analyzed for the detection, identification, and mapping of vegetation and wetlands. The multispectral scanner data were processed digitally while the color and color infrared photography were manually photo-interpreted to define vegetation and wetlands. Several standard image enhancement techniques were applied to the multispectral scanner data to assist image interpretation. A seep enhancement was applied and a color composite consisting of multispectral scanner channels 11, 7, and 5 (thermal infrared, mid-infrared, and red bands, respectively) proved most useful for detecting seeps, seep zones, and springs. The predawn thermal infrared data were also useful in identifying and locating seeps. The remote sensing data, mapped wetlands, and ancillary Geographic Information System compatible data sets were spatially analyzed for seeps.

    Full Text Available Flood protection systems with their spatial effects play an important role in managing and reducing flood risks. The planning and decision process as well as the technical implementation are well organized and often exercised. However, building-related flood-resilience technologies (FReT are often neglected due to the absence of suitable approaches to analyse and to integrate such measures in large-scale flood damage mitigation concepts. Against this backdrop, a synthetic model-approach was extended by few complementary methodical steps in order to calculate flood damage to buildings considering the effects of building-related FReT and to analyse the area-related reduction of flood risks by geo-information systems (GIS with high spatial resolution. It includes a civil engineering based investigation of characteristic properties with its building construction including a selection and combination of appropriate FReT as a basis for derivation of synthetic depth-damage functions. Depending on the real exposition and the implementation level of FReT, the functions can be used and allocated in spatial damage and risk analyses. The application of the extended approach is shown at a case study in Valencia (Spain. In this way, the overall research findings improve the integration of FReT in flood risk management. They provide also some useful information for advising of individuals at risk supporting the selection and implementation of FReT.

    Dowdall, M.; Standring, W.J.F.

    2008-12-01

    Although floating nuclear power plants are not a new concept, all indications are that Russia, amongst other countries, has identified FNPP's (floating nuclear power plants) as one of a range of potential power solutions for both the domestic and international commercial market, utilising LCNPP's (low-capacity nuclear power plants). This focus on LCNPP's in general and LCNPP's in particular appears to be a key part of Russia's positioning of itself as a future leader in the global nuclear energy market. Given the fact that much of the support infrastructure for Russia's existing civilian nuclear fleet is located in the northern regions, the development of FNPP's as part of the nuclear industry is a matter of some interest to a number of countries including Norway. Although FNPP technology is not new, the business models being proposed to effectively commercialise FNPP's as a product on the international market are somewhat novel. This novelty may place FNPP's in a relatively grey area with respect to international laws and regulations. This situation is however also a product of recent developments and initiatives regarding the global nuclear industry and how it operates in the 21st century and the consideration of such business models by countries other than Russia means that it may not be unique to either FNPP's or Russia. A review of the available information indicates that FNPP's may be constructed, located and operated in the Russian Arctic region for a variety of purposes (civilian power/heat generation, resource extraction etc.) as well as being made available for export internationally for purposes such as desalination. Russia is and has been engaged in marketing of such systems to a wide range of potential customers. Information as to potential FNPP technologies is available from a range of sources which indicate a suite of potential designs that may be used in FNPP systems.

    field experiments using the Biochar technology. Here we report the results. As a province with the dominating agriculture, Guizhou produces 10~30 million tons of crop stalks annually, of which roughly 10% were used as fodder of domestic animals or in some other ways while most were subject to the notorious field combustion. The provincial government has issued policies calling for the exploitation of this renewable resource, no breakthrough, however, has been made toward this goal due to the low economic benefit of the current straw use technologies. Should the straws be used in the biochar way, based on our data of field experiments in Guizhou province, the biomass could yield 300~900 thousand tons of charcoal, which would sequester the atmospheric CO2 by 10~30 million tons. Meanwhile the application of the biochar in the basic farmland would enhance the production of corn and rapeseed by about 30%, and the total production of crop by 300 thousand tons. The increased benefit from these two sources is equivalent to a total of 6600 million RMB, or 244 Yuan per capita of farmers per year in the whole province. This income would enable 850 thousand hectares of hill slopes to be relieved from cultivation without impairing the food security. This area accounts for 25% of the total rocky desertification of the province, or 65% of its medium ~severe desertified hillsides. *This research was financially supported by the Strategic Priority Research Program of the Chinese Academy of Sciences (No. XDA05070400), the National Natural Science Foundation of China (No. 41021062, 40872212) and the Key Technologies R & D Project in Agriculture of Guizhou Province (No.[2011]3079).

    Full Text Available BACKGROUND: A detrimental interaction between smoking and alcohol consumption with respect serum γ-glutamyltransferase (γ-GT has recently been described. The underlying mechanisms remain unknown. The present work aimed to provide further insights by examining similar interactions pertaining to aspartate and alanine transaminase (AST, ALT, routine liver markers less prone to enzyme induction. METHODOLOGY/PRINCIPAL FINDINGS: The present cross-sectional analysis was based on records from routine occupational health examinations of 15,281 male employees predominantly of the construction industry, conducted from 1986 to 1992 in Southern Germany. Associations of smoking intensity with log-transformed activities of γ-GT, AST, and ALT were examined in regression models adjusted for potential confounders and including an interaction of smoking with alcohol consumption or body mass index (BMI. Statistically significant interactions of smoking were observed with both alcohol consumption (AST and ALT, each with P<0.0001 and BMI (AST only, P<0.0001. The interactions all were in the same directions as for γ-GT, i.e. synergistic with alcohol and opposite with BMI. CONCLUSION: The patterns of interaction between smoking and alcohol consumption or BMI with respect to AST and ALT resembled those observed for γ-GT. This renders enzyme induction a less probable mechanism for these associations, whereas it might implicate exacerbated hepatocellular vulnerability and injury.

    An AST/ALT ratio > 1 is predictive of liver fibrosis and cirrhosis in patients with chronic hepatitis C virus infection. The aim of this case-control study is to assess AST/ALT ratio in 150 workers exposed to VCM (E) from the beginning of the 1960s to the end of the 1990s. The non-exposed group (NE) consists in 150 male workers employed in the production of a food industry. At least since 1983 exposed subjects worked at VCM environmental concentrations 1 significantly higher than non-exposed. The mean AST/ALT ratio results significantly higher in the exposed group, also after stratification for alcohol consumption. In exposed workers who consume alcoholic beverages and are operating since before 1983 AST/ALT ratio is significantly and positively influenced only by the working age until 1983. If these results will be confirmed, AST/ALT ratio could be proposed to be included in the periodic medical surveillance of VCM workers.

    This study was carried out to evaluate the association of genetic polymorphism -670A>G in the promoter of Fas gene as well as serum biomarkers aspartate aminotransferase (AST) platelet ratio index (APRI) and AST/alanine aminotransferase (ALT) with significant fibrosis and cirrhosis in chronic hepatitis C patients. Seventy-nine patients with chronic hepatitis C in addition to 80 age- and sex-matched healthy controls were evaluated for genetic polymorphism -670A>G of Fas gene by polymerase chain reaction-restriction fragment length polymorphism and serum biomarkers APRI and AST/ALT in relation to significant fibrosis and cirrhosis diagnosed by liver biopsy. Genetic polymorphism -670A>G in Fas gene was associated with significant liver fibrosis and cirrhosis. Heterozygous mutation was found in 11.4% of patients and 10% of controls, while homozygous mutation was found only in 7.6% of patients. Odds ratio (OR) was statistically not significant (OR=1.93, 95% confidence interval=0.76-4.92). Mean values of APRI and AST/ALT were significantly higher in patients with (F3-F4) compared with those with (F0-F2). (p-value G of Fas gene was associated with significant fibrosis and cirrhosis in chronic hepatitis C patients. APRI and AST/ALT are independent predictors for significant fibrosis. APRI showed a better sensitivity than AST/ALT for prediction of significant fibrosis. Moreover, APRI can be used as an index to exclude liver cirrhosis without performing liver biopsy.

    Aging services technologies (ASTs), health technology that meets the needs of seniors, are being underutilized due to a lack of awareness. This study evaluated a video-based educational program to increase AST awareness. Two hundred and thirty-one older adults completed AST measures pre- and post-program. Participants endorsed significantly improved AST knowledge and attitude and a lower level of perceived stigma post-program. Hierarchical regression analyses showed that a greater reduction in stigma post-program and a higher number of physical/cognitive needs supported by ASTs at baseline were significant predictors of a greater increase in expressed intention to use ASTs following the video program. Furthermore, individuals living in their own homes, with a lower level of education, fewer physical and/or cognitive needs supported by ASTs at baseline, and greater functional limitations were found to be more likely to report a significant reduction in perceived stigma post-program. Four-week follow-up data from 75 individuals showed stable program gains. Program feedback was positive. The current findings provide support for the utility of the AST videos. The educational materials used in this study can be used clinically or for public health education to increase awareness and adoption of ASTs. Copyright © 2017 Elsevier B.V. All rights reserved.

    Nuclear heating stations provide one possibility of supplying nuclear heat. They are uniquely intended for heat supply. The well-known Soviet nuclear heating station AST-500 with an output temperature of 150 0 C in the network pipes is below the value designed for some heat supply systems in the GDR. On the basis of a general method applicable to the choice of optimum parameters, proposals are placed for optimally matching design and layout of the AST-500 station to higher output temperatures. Minimization of the difference in expenses between the modified version and the well-known basic version of the AST-500 station has been used as the objective function of optimization. (author)

    We present a measurement of angular observables, $P_4'$, $P_5'$, $P_6'$, $P_8'$, in the decay $B^0 \\to K^\\ast(892)^0 \\ell^+ \\ell^-$, where $\\ell^+\\ell^-$ is either $e^+e^-$ or $\\mu^+\\mu^-$. The analysis is performed on a data sample corresponding to an integrated luminosity of $711~\\mathrm{fb}^{-1}$ containing $772\\times 10^{6}$ $B\\bar B$ pairs, collected at the $\\Upsilon(4S)$ resonance with the Belle detector at the asymmetric-energy $e^+e^-$ collider KEKB. Four angular observables, $P_{4,5,6,8}'$ are extracted in five bins of the invariant mass squared of the lepton system, $q^2$. We compare our results for $P_{4,5,6,8}'$ with Standard Model predictions including the $q^2$ region in which the LHCb collaboration reported the so-called $P_5'$ anomaly.

  19. Measurement prospects for VBF $H{\\rightarrow\\,}WW^{(\\ast)}{\\rightarrow\\,}e\

    2016-01-01

    This note presents the prospects for the ATLAS experiment to observe and measure Vector Boson Fusion (VBF) Higgs-boson production, with the Higgs boson decaying into two $W$ bosons in the High Luminosity LHC environment. The production of two forward jets in association with the Higgs boson, as well as the requirement that the $W$ bosons both decay to leptons, provides a distinctive detector signature. The VBF production process has the second largest Higgs-boson production cross-section at the LHC and can be computed with small theoretical uncertainties. These properties allow for precision measurements in the High Luminosity LHC with 3 $\\textrm{ab}^{-1}$ of data. In addition, measurements of the VBF $H{\\rightarrow\\,}WW^{(\\ast)}{\\rightarrow\\,}e\

    Full text: Soon after the discovery of fission and recognition of its potential for power production, Atomic Research Commission (ARC) was formed under the Chairmanship of Dr. Homi J. Bhabha, which was later renamed, first as Board of Research in Atomic Energy (BRAE) and subsequently as Board of Research in Nuclear Sciences (BRNS) in late fifties under the Department of Atomic Energy (DAE). The BRNS, right from its inception, has been playing an important role of assisting leading universities, academic and R and D institutions in the country for their participation in the departmental program and also in developing skilled human resources in the country for implementing the DAE's programs. Today BRNS has multiple programs which include; sponsored R and D programs in academic and R and D institutes, conducting/supporting international and national conferences, symposia, seminars, workshops in the advanced thematic areas in nuclear science and technology, building Centres of Excellence by way of equipping laboratories with the state-of-the-art experimental facilities and by way of nurturing the local talent. The program has also effective mechanism to strengthen the DAE-university interface through numerous fellowship schemes which cater to students, research scholars and academic staff in the country .The activities of BRNS have been recently further extended to implement the Prospective Research Funding (PRF) scheme under the current Xlth plan project for research scholars from within the department. Possibilities of establishing linkages with the private R and D houses are also being explored. The present talk will give a quick glimpse of the BRNS activities and illustration of some of the important achievements under its programs. The talk is also aimed at further increasing the awareness about the mechanisms and opportunities for participation in the BRNS activities for the scientists and engineers within and outside the department

    The serum asparate aminotransferase (AST)/alanine aminotransferase (ALT) ratio is widely used in the differential diagnosis of icteric and non-icteric hepatic disorders. Our objective was to determine whether there are gender related-differences in the serum AST/ALT ratio. We used sera from 3,618 unselected patients sent to our laboratory for an automated chemistry panel, which included measurements of AST, ALT, alkaline phosphatase, and total bilirubin. Effects of gender on serum AST, ALT, and AST/ALT were examined in different age groups. Among patients with normal total serum bilirubin concentrations, serum AST and ALT concentrations were significantly lower in the females than in the males (P < 0.0001). However, the serum AST/ALT ratio was higher in the females than the males (median values of 0.90 and 0.81, respectively; P < 0.0001). AST and ALT were also lower in the 54 hyperbilirubinemic females than in the 102 hyperbilirubinemic males. Serum AST/ALT ratios were considerably higher in these 156 hyperbilirubinemic patients than in the normobilirubinemic group, with median ratios of 1.09 in females and 0.92 in males (P = 0.02). Significantly higher serum AST/ALT ratios in females were first evident in the 3rd age decade and remained significantly higher than ratios in males through the 8th decade. We conclude that serum AST/ALT ratios are higher in women than men. When clinicians utilize serum AST/ALT ratios to assess the etiology or chronicity of liver disease, the patient's gender also should be taken into consideration.

    Recently, so many medical institutions established and the increasing use of the high technological medical imaging equipment, it makes radiological technology become the main instrument for the medical diagnostic and radiation therapy. However, the medical radiological technologies play the important role to operate all the related radiological machines. If they do not use the machines adequately, it will increase the patients' radiation absorbed dose. Then, the whole society health may be influenced. Therefore, constructing the professional competence of the medical radiological technologists is an important course. The purpose of this research are: (1) to construct the index of professional competence with radiological technology students, (2) to discuss the professional competence for the graduates from the department of radiological technology to be the reference for the Ministry of Examination for the license test of radiological technologists, (3) to provide the direction of the radiological technology department development.

    To evaluate the effects of Norplant (36 mg of levonorgestrel, six capsules) on serum cholesterol, triglycerides, alanine transaminase (ALT) and aspartate transminase (AST), we enrolled 465 healthy women from Zahedan, Iran, into a longitudinal study. Blood samples were collected after an overnight fast before implant insertion and after 3, 6, 9 and 12 months of use. Total cholesterol and triglyceride levels did not significantly change during Norplant use. Although there were statistically significant increases in ALT and AST levels during Norplant use, the values were within the reference range.

    The central question in this report is: how do climate change policies on the one hand and the liberalisation of energy markets on the other hand influence the role of new energy technology? To address this question, technological, economical and societal aspects have been studied. With regard to technological aspects a list is made of technologies which could become important when a 50% reduction of annual Dutch CO 2 emission must be realized in the year 2050. For each of these technologies, future energy efficiencies are estimated. Using these figures, three 'blue prints' of the energy supply system in 2050 are described. In two of these blueprints the energy infrastructure changes drastically, in that electricity or hydrogen becomes the dominant final energy carrier in all end-use sectors. In the third blueprint the current final energy carriers (methane, electricity and gasoline/diesel) maintain their dominant position. With regard to economical aspects, 14 interviews were held with representatives of a wide range of companies in the energy sector, focusing on the role of technology in the company strategy. With regard to societal aspects, a number of important energy technologies are analysed in terms of how much societal support or resistance can be expected when these technologies are implemented on a large scale. Also representatives of two environmental organisations and a consumer organisation were interviewed. 75 refs

    Full Text Available Often centralized water supply, sanitation and solid waste services struggle to keep up with the rapid expansion of urban areas. The peri-urban areas are at the forefront of this expansion and it is here where decentralized technologies are increasingly being implemented. The introduction of decentralized technologies allows for the development of new opportunities that enable the recovery and reuse of resources in the form of water, nutrients and energy. This resource-oriented management of water, nutrients and energy requires a sustainable system aimed at low resource use and high recovery and reuse rates. Instead of investigating each sector separately, as has been traditionally done, this article proposes and discusses a concept that seeks to combine the in- and outflows of the different sectors, reusing water and other liberated resources where possible. This paper shows and demonstrates examples of different types of sustainable technologies that can be implemented in the peri-urban areas of Mexico City [rainwater harvesting, EcoSan and biofiltros (small constructed wetlands, and (vermi-composting]. An innovative participatory planning method, combining scenario development with a participatory planning workshop with key stakeholders, was applied and resulted in three concept scenarios. Specific technologies were then selected for each concept scenario that the technical feasibility and applicability was assessed. Following this, the resulting resource flows (nutrients, water and energy were determined and analyzed. The results show that decentralized technologies not only have the potential to deliver adequate water supply, sanitation and solid waste services in peri-urban areas and lessen environmental pollution, but also can recover significant amounts of resources thereby saving costs and providing valuable inputs in, for instance, the agricultural sector.

This paper presents and analyses the blood cells count and clinical chemistry of alanine aminotransferase (ALT, aspartate aminotransferase (AST and creatinine of a southern elephant seal, Mirounga leonina (LINNAEUS, 1758, found on February the 11th at Barra Beach, Salvador, BA. The specimen was an orphan male calf, with 137cm of length and estimated weight of 49kg. It presented bad nutritional conditions and a shark bite on the right shoulder area. Clinical management was performed for 56 days, anthelmintic Febendazole was utilized, and the bite was treated with iodined alcohol, Nitrofurazone solution and Kethanserin, simultaneously with Enrofloxacin 10%, Potenay®, Vitamin B Complex and Benerva®. On the 16th the animal presented a right unilateral conjuntivitis, treated with Cloranphenicol oftalmic pomade until the end of its stay in the captive. During this period a total of six blood samples were collected, three for total blood counts and the others for the biochemistry determination of ALT, AST and creatinine. According to the haematological analysis the seal developed an anaemia which was classified as microcytic and normochromic. Lymphopenia, eosinopenia and monocytopenia were also observed, possibly due to its handling and stress conditions. The clinical chemistry presented low values for AST and creatinine, although this did not represent the existence of any pathologic context or disease with clinical significance.

    The usefulness of the serum aspartate aminotransferase (AST): serum alanine aminotransferase (ALT) ratio as a guide to the presence of alcoholism was evaluated in four groups of patients. In alcoholics with elevated transaminases the mean AST:ALT ratio was found to be 1.50 (95% confidence interval (CI): 1.49-1.51), in hepatitis B infection 0.51 (95% CI: 0.50-0.52), in liver cancer 1.25 (95% CI: 1.20-1.29), and in nonmalignant obstructive jaundice 0.59 (95% CI: 0.57-0.61). In alcoholics with normal transaminases the AST:ALT ratio was 1.64 (95% CI: 1.61-1.67). The combination of an AST:ALT ratio of greater than 1.00 with an erythrocyte mean cell volume (MCV) above 90.0 fL resulted in a sensitivity of 97.3% and a specificity of 88.9% for detecting alcoholism in these four groups of patients.

    This study aimed to investigate the protective effects of magnesium isoglycyrrhizinate (MGL) on aspartate aminotransferase (AST), alanine aminotransferase (ALT), and serum levels of T helper 1 (Th1) cytokines in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). The study included 42 patients prepared for allo-HSCT, who were divided equally into MGL and reduced glutathione groups. The ALT and AST levels were detected 1day before pretreatment and transplantation, and 7, 14, and 21days after transplantation. The total days and times of fever, treatment time of patients in the laminar flow room, white blood cell (WBC) count, platelet (PTL) implantation time, and success rate of transplantation were recorded. The serum levels of Th1/Th2 cytokines were detected. MGL had a significant protective effect on AST 1day before transplantation and 7, 14, and 21days after transplantation, while ALT had a statistical difference only 7days after transplantation. MGL could shorten the duration of fever during transplantation and advance the WBC and PTL implantation time. Significant differences in Th1-like cytokines (P0.05) were found in the MGL group compared with the control group. MGL had significant protective effects on AST after transplantation. MGL could reduce the duration of fever during transplantation, help the reconstruction and recovery of WBCs and PTLs, and regulate Th1 cytokines, revealing its protective effects on hepatic transaminases and graft versus host disease in allo-HSCT patients.

    This study was conducted to develop market intelligence related to clean energy technologies in Northern California, including both commercial and demonstration technologies. The study was developed as a tool for exploring engagement between Canadian and Californian businesses and partnering opportunities. The study examined technologies for solar power and photovoltaics; hydrogen and fuel cells; and waste-to-energy. A list of more than 150 organizations, government agencies, business associations, and utilities was prepared. The survey also included the establishment of contact points with large facilities, public spaces, bus fleets, and major capital projects. Fifty-nine interviews were also conducted as part of the study. Results of the study indicated that the biggest challenge concerning most individuals was the need to reduce energy consumption while maintaining reliability. Many interviewees expressed an interest in operating waste-to-energy facilities. Fifty interviewees indicated that they were planning to use or already used solar technologies. An analysis of clean energy needs was also included. The study indicated that many local governments are reluctant to embrace new, highly visible technologies. Only sophisticated organizations with unique energy demands have considered the use of fuel cell technologies. 1 fig

    Due to the poor condition of soil and micro-climate condition, the mudstone area in the southwestern Taiwan has been difficult for plants to grow. The area is always in such a bare condition that it is nicknamed "Moon World." Serious erosion and natural disasters in the mudstone area are the significant problems for soil and water conservation, and the area of bald mudstones is expanding. Statistical data show that bare area has increased 3 times during the past 10 years. The mudstone area in the southwestern Taiwan was hard to plant and then it always in bare condition which got a nickname of The Moon World. The distribution of each land-use type in mudstone area, and spatial information in years were integrated into GIS by ArcView. In the respect of ecosystem, ecological index in different periods were calculated based upon landscape ecological theory. To explain its meanings and the danger behind the bare mudstone area, the results indicated that mosaic gathering was caused by mudstone and thorn bamboo. The results illustrated that the ecological factor of landscape such as patch shape factor, and Shannon evenness factor that have significant canonical correlation with water qualities and erosion of the study area. In study area, there are many styles of fracture, variation, and mosaic distribution landscape.

    The Idaho National Engineering Laboratory (INEL) Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates Environmental Restoration (ER) and Waste Management (WM) problems at the INEL to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to an environmental restoration need. It is essential that follow-on engineering and system studies be conducted to build on the output of this project. These studies will begin by selecting the most promising technologies identified in this TLD and finding an optimum mix of technologies that will provide a socially acceptable balance between cost and risk to meet the site windows of opportunity. The TLD consists of three separate volumes: Volume I includes the purpose and scope of the TLD, a brief history of the INEL Waste Area Groups, and environmental problems they represent. A description of the TLD, definitions of terms, a description of the technology evaluation process, and a summary of each subelement, is presented. Volume II describes the overall layout and development of the TLD in logic diagram format. This section addresses the environmental restoration of contaminated INEL sites. Volume III (this volume) provides the Technology Evaluation Data Sheets (TEDS) for Environmental Restoration and Waste Management (EM) activities that are reference by a TEDS code number in Volume II. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than provided for technologies in Volume II. Data sheets are arranged alphanumerically by the TEDS code number in the upper right corner of each sheet.

  1. Hydrogen storage for vehicular applications: Technology status and key development areas

    The state-of-the-art of hydrogen storage technology is reviewed, including gaseous, liquid, hydride, surface adsorbed media, glass microsphere, chemical reaction, and liquid chemical technologies. The review of each technology includes a discussion of advantages, disadvantages, likelihood of success, and key research and development activities. A preferred technological path for the development of effective near-term hydrogen storage includes both cur-rent DOT qualified and advanced compressed storage for down-sized highly efficient but moderate range vehicles, and liquid storage for fleet vehicle applications. Adsorbate media are also suitable for fleet applications but not for intermittent uses. Volume-optimized transition metal hydride beds are also viable for short range applications. Long-term development of coated nanoparticulate or metal matrix high conductivity magnesium alloy, is recommended. In addition, a room temperature adsorbate medium should be developed to avoid cryogenic storage requirements. Chemical storage and oxidative schemes present serious obstacles which must be addressed for these technologies to have a future role.

    In a previous article, a correlation is made among the phases of the nuclear technology development and the decision making processes, showing that from the 70's decade, such processes are connected to the national security doctrines, influenced by the Brazilian War College. In this paper it is shown the developed model for the decision making when the sensitive technologies are involved that in our special case will be specific oriented to the nuclear technology. An assessment are made for such decisions must having the the population approval, showing the main existent obstacles and how the present model, although defined at the end of the year 2003, will not be succeeded in a short period of time. It is mainly shown that the linear models must be abandoned, essential since the Word War II, for a holistic model more realistic with a new global state of affairs

    Full Text Available The article is devoted to nano- and femtotechnology as the basis for sustainable noosphere development of the global socio-economic mega system “nature–man–society” in its relation with the Universe (cosmos in Belarus, Kazakhstan, Russia, Ukraine and other CIS nations. Such factors as the formation of a new (noospheric political and economic outlook and the changes in scientific and technological structure of economy are gaining paramount importance under the action of the law of time and the adequate need to change the logic of socio-economic behavior of the population of planet Earth. Singular technology can become a strategic priority in finding practical solutions to these issues. When creating new productive forces and relations of production, these technologies act as a synergetic and bifurcation (unpredictable interaction of the three system technologies: artificial intelligence, molecular nanotechnology and molecular biotechnology. As soon as man grasps the essence of singular technology, it will be possible to create a new structure of matter at the nano- and femtotechnology levels, and to exercise control over this process. The new structure of matter is the basis for the creation of new productive forces and relations of production in the noosphere economy. Technological singularity originated in the mapping of the human genome, creation of a self-replicating organism, and a self-replicating machine. The nearest strategic objective (2020–2030s of singular technology is to create an artificial brain – a “digital man” on the basis of nano-and femtotechnology. This research area and practice will open the way to new forms of energy, productive forces, industrial relations and socio-economic noosphere systems in general. The wide application of singular technology in the economy will contribute to the conservation and civilizational development of the planetary megasystem “cosmos–nature–man–society”

    We report the observation of Higgs boson decays to $WW^{\\ast}$ based on an excess over background of 6.1 standard deviations in the dilepton final state, where the Standard Model expectation is 5.8 standard deviations. Evidence for the vector-boson fusion (VBF) production process is obtained with a significance of 3.2 standard deviations. The results are obtained from a data sample corresponding to an integrated luminosity of $25~\\textrm{pb}^{-1}$ from $\\sqrt{s}=7$ and 8 TeV $pp$ collisions recorded by the ATLAS detector at the LHC. For a Higgs boson mass of 125.36 GeV, the ratio of the measured value to the expected value of the total production cross section times branching fraction is $1.09^{+0.16}_{-0.15}~\\textrm{(stat.)}^{+0.17}_{-0.14}~\\textrm{(syst.)}$. The corresponding ratios for the gluon fusion and vector-boson fusion production mechanisms are $1.02\\pm 0.19~\\textrm{(stat.)}^{+0.22}_{-0.18}~\\textrm{(syst.)}$ and $1.27^{+0.44}_{-0.40}~\\textrm{(stat.)}^{+0.30}_{-0.21}~\\textrm{(syst.)}$, respectively. ...

    Oxytocin (OT) is primarily synthesized in the paraventricular nucleus of the hypothalamus and supraoptic nucleus of the hypothalamus in the central nervous system and exhibits a wide spectrum of central and peripheral activities. OT is involved in lipid metabolism and glucose homeostasis and plays a protective role against liver damage. In this study, we investigated whether CSF OT levels correlates with peripheral glucose, lipid profiles, and/or liver enzymes in Chinese subjects. Sixty-nine subjects (n=36 males; n=33 females) who were recruited from Beijing Jishuitan Hospital participated in the study. Their levels of CSF OT and peripheral parameters were assayed by radioimmunoassay and continuous monitoring assay, respectively. There was no significant difference in CSF OT levels between males (53.09±6.88 nmol/mL) and females (52.34±6.87 nmol/mL), and no correlation found between CSF OT levels and peripheral glucose and lipid profiles. Significant negative correlation was observed between CSF OT levels and peripheral ALT and AST concentration in females but not in males. Our results support the physiological role of neuropeptides acting on brain sites to regulate liver enzymes, and shed new light on the brain-liver interaction.

    The first of three Antarctic Survey Telescopes (AST3-1), a 50/68cm Schmidt-like equatorial-mount telescope, is the first trackable Chinese telescope operating on the Antarctic plateau. It was installed at Dome A (80°22', 77°21'E, 4,093m), the highest place on the Antarctic plateau, in 2012. The telescope is unmanned during night-time operations through the Austral winter. The telescope optics and mechanics, as well as the motors and position sensors, are exposed to a harsh environment. The mechanics is enclosed with a foldable tent-like dome to prevent snow, diamond dust and ice. While the control cabinet containing drive boxes, circuit board boxes, power converters and the Telescope Control Computer (TCC) is located inside the warm instrumental module. In about 15 weeks remote testing and commissioning, from January 24 when the expedition team left there to May 8, when the communication failed, we obtained images with the best FWHM of less than 2''. We also recorded the telescope movement performance and fine-tuned the dynamic properties of the telescope control system. Some experiences and lessons will be disscussed in this paper.

    National priorities, defined by modern state of high-tech industries, demand adequate problem solving of training professionals possessing required modern qualifications. Modern tendencies of the development of aerospace technologies, harsh competition in the market of space services and expansion of international cooperation for implementation of space projects, demand sharp increase of the scientific/technical level and competitiveness of the developed projects. Especially important is to be able to solve technological problems, which in turn define the cost and quality attributes of the designed item, as well as the ability to utilize the most modern design principles. Training of highly efficient, creative professionals who are capable of generating and implementing new ideas is a very important factor driving not only the development of national economy and industry, but also enriching the human capital of the country. Moscow State Technical University named after N.E. Bauman developed and successfully implemented the project-oriented technology of professional training for aerospace industry. It assumes a multitude of forms, methodologies and organizational events, which allow preparing the specialists - on the basis of integration of scientific/technological and educational environment - who are adapted to the conditions of the intellectual market. The Youth Space Center of the University is the base where graduate and post-graduate students attend unique lectures as a part of the facultative course "Applied Cosmonautics", participate in annual International Youth Science School "Space Development: Theory and Practice" and develop innovative technical projects aimed at creation of real-life space hardware. Microsatellite technologies are being developed in Bauman University through various projects, which are implemented in a coordinated manner by way of accomplishing the following steps: development of small-size satellites by universities, using them as

  12. Foreknowledge of breakthroughs science and technology foresight, and the early identification of areas of breakthrough

    International Nuclear Information System (INIS)

    Papon, P.

    2010-01-01

    The progress of science and technology has been so rapid in the last few decades that it receives especial attention in forecasting and foresight exercises. But, because they are too greatly in thrall to the dominant paradigms and hence favour a linear perspective, the experts who deal with these questions pay more attention to the future of technologies than to scientific advances and revolutions. The bulk of their work consists, then, in anticipating, by various different methods (Delphi surveys, Road-maps, etc.), at what date a particular technology might be available (without, however, always correctly gauging the conditions for its social appropriation or the applications to which it might be put). In this article, Pierre Papon expounds a much more original and promising approach for attempting to anticipate the discoveries that are likely radically to transform the fields of scientific knowledge by investigating the phenomena that may potentially lead to fundamental revolutions. After reminding us of the premonitory thinking of a number of authors - in the fields, for example, of genetics and computer science -, he endeavors to describe some of the dominant paradigms, particularly in quantum physics and molecular biology. In this way, he shows the advances they have made possible, and also their limitations, and explores what new scientific leaps forward might occur, bringing radically new technological breakthroughs between now and 2050. Papon reminds us, at the same time that, 'as science is not something isolated within society'; it has a duty to contribute to meeting the great challenges that face us - of work, health, nutrition and sustainable development, particularly where energy and climate are concerned. He therefore examines the ways in which future scientific and technological advances might provide solutions and how important it might be to 'translate the questions society poses into scientific questions'. He thus argues implicitly for strategic

  13. Key seismic exploration technology for the Longwangmiao Fm gas reservoir in Gaoshiti–Moxi area, Sichuan Basin

    Full Text Available The dolomite reservoirs of the Lower Cambrian Longwangmiao Fm in the Gaoshiti–Moxi area, Sichuan Basin, are deeply buried (generally 4400–4900 m, with high heterogeneity, making reservoir prediction difficult. In this regard, key seismic exploration technologies were developed through researches. Firstly, through in-depth analysis on the existing geologic, drilling, seismic data and available research findings, basic surface and subsurface structures and geologic conditions within the study area were clarified. Secondly, digital seismic data acquisition technologies with wide azimuth, wide frequency band and minor bins were adopted to ensure even distribution of coverage of target formations through optimization of the 3D seismic geometry. In this way, high-accuracy 3D seismic data can be acquired through shallow, middle and deep formations. Thirdly, well-control seismic data processing technologies were applied to enhance the signal-to-noise ratio (SNR of seismic data for deep formations. Fourthly, a seismic response model was established specifically for the Longwangmiao Fm reservoir. Quantitative prediction of the reservoir was performed through pre-stack geo-statistics. In this way, plan distribution of reservoir thicknesses was mapped. Fifthly, core tests and logging data analysis were conducted to determine gas-sensitive elastic parameters, which were then used in pre-stack hydrocarbon detection to eliminate the multiple solutions in seismic data interpretation. It is concluded that application of the above-mentioned key technologies effectively promote the discovery of largescale marine carbonate gas reservoirs of the Longwangmiao Fm.

    AST2017-01 mainly consists of Rumex crispus and -Cordyceps militaris and has been widely consumed as an herbal medicine or functional food in Korea. Here we investigated the influences of AST2017-01 and its active component, chrysophanol on human mast cell (HMC-1 cell) and human keratinocyte (HaCaT cell)-mediated inflammatory reactions. Pretreatment with AST2017-01 or chrysophanol suppressed intracellular calcium levels and histamine release in phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-treated HMC-1 cells. Levels of phosphorylated-mitogen-activated protein kinase increased by PMACI stimulation were reduced by AST2017-01 or chrysophanol pretreatment. Protein levels of IκB kinaseβ and receptor-interacting protein 2 in PMACI-treated HMC-1 cells were decreased by AST2017-01 or chrysophanol pretreatment. Pretreatment with AST2017-01 or chrysophanol significantly blocked PMACI-induced activation of caspase-1 and nuclear factor-κB. In addition, pretreatment with AST2017-01 or chrysophanol significantly decreased the PMACI-induced levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-α, and thymic stromal lymphopoietin (TSLP) on HMC-1 cells. In activated HaCaT cells, pretreatment with AST2017-01 or chrysophanol significantly reduced production of TSLP and activation of caspase-1. In conclusion, these findings indicate that chrysophanol is an active component of AST2017-01 and AST2017-01 acts as a novel potent anti-inflammatory herbal medicine or functional food.

  15. Engineering with nuclear explosives near populated areas - A survey from the technological and economic viewpoint

    International Nuclear Information System (INIS)

    Parker, K.

    1970-01-01

    Current experience with underground firings of nuclear explosives and of large charges of conventional explosives is largely confined to sparsely populated areas such as the Nevada and Sahara deserts and parts of Siberia. On the other hand many of the commercial applications proposed for nuclear explosives are directly relevant to industrialized areas, where consumptions of energy and natural resources are high, as are population densities. In many of these areas there is a need to increase the efficiency with which natural gas, oil and electrical power are supplied and to make safe disposal of fluid wastes; completely contained nuclear explosions could be a useful tool in achieving some or all of these aims. Whilst radioactivity and air blast hazards are likely to rule out nuclear cratering operations near densely populated areas, the prospects for carrying out completely contained explosions are much better, providing seismic damage is kept within reasonable bounds. In large areas of Western Europe and on the eastern, southern and western seaboards of the United States this might be achieved by using nuclear explosions beneath the seabed at a reasonable distance from the nearest coastline, always provided the relevant political issues can be resolved. Stimulation and storage of North Sea natural gas, construction of off-shore oil storage and storage of electrical energy are areas where engineering with nuclear explosives merits more detailed investigation and some of the relevant technical problems are discussed.

    In the present paper, the authors use permanent scatterers synthetic aperture radar interferometry (PS-InSAR) technique and 29 acquisitions by Envisat during 2003 to 2009 to monitor and analyze the spatial-temporal distribution and mechanism characterize of land subsidence in Beijing plain area. The results show that subsidence bowls have been bounded together in Beijing plain area, which covers Chaoyang, Changping, Shunyi and Tongzhou area, and the range of subsidence has an eastward trend. The most serious regional subsidence is mainly distributed by the quaternary depression in Beijing plain area. PS-Insar results also show a new subsidence bowl in Pinggu. What's more, the spatial and temporal distribution of deformation is controlled mainly by faults, such as Liangxiang-Shunyi fault, Huangzhuang-Gaoliying fault, and Nankou-Sunhe fault. The subsidence and level of groundwater in study area shows a good correlation, and the subsidence shows seasonal ups trend during November to March and seasonal downs trend during March to June along with changes in groundwater levels. The contribution of land subsidence is also influenced by stress-strain behavior of aquitards. The compaction of aquitards shows an elastic, plastic, viscoelastic pattern.

    Google Street View (GSV) can be used as an effective tool to conduct virtual neighborhood audits. We expand on this research by exploring the utility of a GSV-based neighborhood audit to measure and match target and comparison study areas. We developed a GSV-based inventory to measure characteristics of retail alcohol stores and their surrounding neighborhoods. We assessed its reliability and assessed the utility of GSV-based audits for matching target and comparison study areas. We found that GSV-based neighborhood audits can be a useful, reliable, and cost-effective tool for matching target and comparison study areas when archival data are insufficient and primary data collection is prohibitive. We suggest that researchers focus on characteristics that are easily visible on GSV and are relatively stable over time when creating future GSV-based measuring and matching tools. Dividing the study area into small segments may also provide more accurate measurements and more precise matching. Copyright © 2015 Elsevier Ltd. All rights reserved.

Technology campuses entail a variety of built environments developed to accommodate technology-driven research activities of multiple organisations. The science park is the most common type of technology campus. Other types include the campuses of universities  of technology and corporate R&D parks. In industrialised countries, the demand for developing  technology  campuses  to  stimulate innovation has been growing in line with the attention given to knowledge in global, national and regional policies. There are over 700 technology campuses worldwide occupying hundred thousands  of hectares in- and around cities. This type of built environments have emerged and developed during critical periods of technological advancements throughout the 20th century, to support technology-based development in industrialised countries. With the adoption of the knowledge- based economy, governments in many countries have encouraged research as an essential activity in their science, technology and innovation policies. The infrastructure that supports research is also gaining momentum. The number of registered science parks is steadily increasing since the late 1990s. The number of programmes supporting research infrastructure is growing in the European policy agenda. Municipalities are formally engaged with other public and private parties in the development of urban areas targeted to stimulate innovation. Governments, universities and R&D companies are investing billions of euros in developing the infrastructure that will not only support their core processes, but will help them to remain competitive by attracting and retaining the best talent. Part of these investments are targeted to develop new buildings or entire areas that often result in campuses as we know them: a concentration of buildings accommodating organisations

    The goal of this paper is to show the management results of the 2005-2007 project 'Nuclear energy: itinerant expositions' sponsored by the Foundation for Research Support of Minas Gerais (FAPEMIG), a state agency, in a science and technology popularization program. The project coordinated by the Nuclear Technology Development Center (CDTN/CNEN) in partnership with the Minas Commerce Association (ACMinas) was designed to students from public high school of the Belo Horizonte metropolitan region. It consisted of an exposition and a previous talk motivating the audience to the nuclear technology in connection with subjects taught at schools, like physics, chemistry, biology, mathematics, history, etc. Small scale models of nuclear and radioactive installations, irradiated food and fruits samples and colored gems by gamma rays were presented at the stand exposition. Designing, performing and evaluating the project required the following activities: searching of information on the target public, infrastructure mounting, team training, multimedia material elaboration, strategy for dealing with the students, talk presentation, distribution of booklet on nuclear themes, reception at the exposition, interviews with students and teachers by journalists, evaluation of the project by the schools, evaluation of the project by some students three months after the event and also reporting the project to the media. About forty people of CDTN took part in the project that reached thirty high schools and encompassed about 11,000 students. About five hundred state high school teachers of chemistry, physics and biology were reached by the experience of the project in a specialization course given by a local university. Only high approval was received by the project in the returned questionnaires. (author)

    Mexico City Metropolitan Area (MCMA) is the most populated urban area in the country. In 2010, MCMA required 14.8% of total energy domestic demand, but greenhouse gas emissions accounted for 7.7% of domestic emissions. Mexico has massive renewable energy potential that could be harnessed through solar photovoltaic (PV) technology. The problem to explore is the relationship between local and federal public strategies in MCMA and their stance on energy transition concern, social empowerment, new technology appropriation, and the will to boost social development and urban sustainability. A public policy typology was conducted through instruments of State intervention approach, based on political agenda articulation and environmental local interactions. Social equality is encouraged by means of forthright funding and in-kind support and energy policies focus on non-renewable energy subsidies and electric transmission infrastructure investment. There is a lack of vision for using PV technology as a guiding axis for marginalized population development. It is essential to promote economic and political rearrangement in order to level and structure environmental governance. It is essential to understand people's representation about their own needs along with renewable energy.

  12. The influence of magnesium on the activity of some enzymes (AST, ALT, ALP) and lead content in some tissues.

    Many authors in different studies have reported the antagonism between Mg and Pb. Our previous results suggested that oral Mg treatment have better effect on investigation biochemical parameters (protoporphyrins, aminolevulinic acid--ALA and d-aminolevulinic dehydratase ALA-D) used in evaluating Pb intoxication, then CaNa2EDTA, chelation agents, currently used in therapy of Pb intoxication. The toxic effect of Pb induced considerably modifies the activity of many other enzymes. In this work we have examined the influence of Mg (as alternative therapy of Pb poisoning) on enzymes activity--biochemical markers for general health conditions--aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in condition of lead intoxication. Many studies showed disturbances of activity ALT, AST and ALP. The aim of this study was to confirm positive effects of Mg intake in condition of such intoxication at the level on activity of investigated enzymes. The experiment was performed on 45 male Wister rats, divided in three groups. I--control group; II--group treated daily for 30 days with 100 mg Pb, per kg body weight and next 60 without Pb treatment (spontaneous detoxication); III group--the same treatment as II group for the first 30 days, but next 60 days rats were treated orally with 40 mg Mg/kg body weight. Activity of AST and ALT was significant increased in condition of Pb poisoning, but ALP activity was significant reduced. Influence of excessive oral Mg treatment was positive: decrease of AST activity and ALT activity, which was probably in correlation with significant elimination of Pb from liver and increase of ALT enzyme activity at the normal level.

    The present study aims to clarify the effects of sex, age, BMI and puberty on transaminase serum levels in children and adolescents and to provide new age- and sex-related percentiles for alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyltransferase (GGT). Venous blood and anthropometric data were collected from 4,126 cases. Excluded were cases of participants with potential hepatotoxic medication, with evidence of potential illness at the time of blood sampling and non-normal BMI (BMI  90 th ). The resulting data (N = 3,131 cases) were used for the calculations of ALT, AST, and GGT percentiles. Age- and sex-related reference intervals were established by using an LMSP-type method. Serum levels of transaminases follow age-specific patterns and relate to the onset of puberty. This observation is more pronounced in girls than in boys. The ALT percentiles showed similar shaped patterns in both sexes. Multivariate regression confirmed significant effects of puberty and BMI-SDS (β = 2.21) on ALT. Surprisingly, AST serum levels were negatively influenced by age (β = -1.42) and BMI-SDS (β = -0.15). The GGT percentiles revealed significant sex-specific differences, correlated positively with age (β = 0.37) and showed significant association with BMI-SDS (β = 1.16). Current reference values of ALT, AST and GGT serum levels were calculated for children between 11 months and 16.0 years, using modern analytical and statistical methods. This study extends the current knowledge about transaminases by revealing influences of age, sex, BMI, and puberty on the serum concentrations of all three parameters and has for these parameters one of the largest sample sizes published so far.

    The present study aimed to investigate the effect of ZnO nanoparticles on alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) enzyme expressions in C2C12 cells. ZnO nanoparticles are widely used in the several cosmetic lotions and other biomedical products. Several studies report on ZnO nanoparticle mediated cytotoxicity. However, there are no reports on the effect of ZnO nanoparticles on ALT, AST, ALP and LDH enzyme expressions in C2C12 cells. A cytotoxicity assay was carried out to determine the effect of ZnO nanoparticles (1-5 mg/ml) on C2C12 cell viability at 48 and 72 h. ZnO nanoparticles increased ALT, AST, ALP and LDH enzyme mRNA expression and their activities in C2C12 cells. In conclusion, the present study showed that ZnO nanoparticles increased these enzyme activities and its mRNA expression in C2C12 cells in a dose-dependent manner.

    Reference intervals are widely used as decision tools, providing the physician with information about whether the analyte values indicate ongoing disease process. Reference intervals are generally based on individuals without diagnosed diseases or use of medication, which often excludes elderly. The aim of the study was to assess levels of albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine and γ-glutamyl transferase (γ-GT) in frail, moderately healthy and healthy elderly indivuduals. Blood samples were collected from individuals >80 years old, nursing home residents, in the Elderly in Linköping Screening Assessment and Nordic Reference Interval Project, a total of 569 individuals. They were divided into three cohorts: frail, moderately healthy and healthy, depending on cognitive and physical function. Albumin, ALT, AST, creatinine and γ-GT were analyzed using routine methods. Linear regression predicted factors for 34% of the variance in albumin were activities of daily living (ADL), gender, stroke and cancer. ADLs, gender and weight explained 15% of changes in ALT. For AST levels, ADLs, cancer and analgesics explained 5% of changes. Kidney disease, gender, Mini Mental State Examination (MMSE) and chronic obstructive pulmonary disease explained 25% of the variation in creatinine levels and MMSE explained three per cent of γ-GT variation. Because a group of people are at the same age, they should not be assessed the same way. To interpret results of laboratory tests in elderly is a complex task, where reference intervals are one part, but far from the only one, to take into consideration.

Cows were divided into the groups: lactation (Group A, postpartal period within 15 days from calving (Group B and dry period (Group C. Seasonal variations affected AST activity within Groups A and B, while Group C showed no seasonal influence. Differences between Groups A and B were determined during winter, as well as among Groups A and C during the same season. The highest activity of ALT was measured in cows from Group A during the winter season. ALP activity showed no statistical difference among groups, though statistical significance was noted within seasonal changes. The activity of LDH showed no statistical significance within Group C with regard to the seasonal changes. Statistically significant difference was found between cows of Group A and C during the winter season. Differences were considered statistically significant when p<0,05.Research results showed a significant influence of milk production and dry period on the activities of measured enzymes in the blood plasma so we can conclude that there is a need for constant monitoring of the described parameters during the production period.Key words: dairy cows, ALT, AST, ALT, LDH

  2. RESULTS FROM RECENT SCIENCE AND TECHNOLOGY INVESTIGATIONS TARGETING CHROMIUM IN THE 100D AREA HANFORD SITE WASHINGTON USA

    Sodium dichromate was used in Hanford's 100D Area during the reactor operations period of 1950 to 1964 to retard corrosion in the reactor cooling systems. Some of the sodium dichromate was released to the environment by spills and/or leaks from pipelines used to deliver the chemical to water treatment plants in the area. As a result, hexavalent chromium [Cr(VI)] has migrated through the vadose zone to the groundwater and contaminated nearly 1 km{sup 2} of groundwater to above the drinking water standard of 48 {micro}g/L. Three technology tests have recently been completed in this area to characterize the source area of the plumes and evaluate alternative methods to remove Cr(VI) from groundwater. These are (1) refine the source area of the southern plume; (2) test electrocoagulation as an alternative groundwater treatment technology; and (3) test the ability to repair a permeable reactive barrier by injecting micron or nanometer-size zero-valent iron (ZVI). The projects were funded by the US Department of Energy as part of a program to interject new technologies and accelerate active cleanup. Groundwater monitoring over the past 10 years has shown that Cr(VI) concentrations in the southern plume have not significantly diminished, strongly indicating a continuing source. Eleven groundwater wells were installed in 2007 and 2008 near a suspected source area and monitored for Cr(VI) and groundwater levels. Interpretation of these data has led to refinement of the source area location to an area of less than 1 hectare (ha, 2.5 acres). Vadose zone soil samples collected during drilling did not discover significant concentrations of Cr(VI), indicating the source is localized, with a narrow wetted path from the surface to the water table. Electrocoagulation was evaluated through a pilot-scale treatability test. Over 8 million liters of groundwater were treated to Cr(VI) concentrations of {le}20 {micro}g/L. The test determined that this technology has the potential to

    The aspartate aminotransferase activity (AST)/alanine aminotransferase activity (ALT) ratio is used as liver fibrosis index whereas the reported data are conflicting. In chronic hepatitis C (CHC), reported diagnostic accuracies range from none to good for significant fibrosis and to excellent for cirrhosis. Assuming that AST/ALT increases are mainly due to vitamin B6 defects since pyridoxal phosphate (PLP), active form of B6, acts as coenzyme in transamination reactions, we evaluated the diagnostic accuracy of the AST/ALT ratio using standardized methods for AST and ALT activities, with PLP addition as recommended, in a prospective multicenter cohort of CHC patients. ALT and AST activities were measured using the recommended IFCC methods with addition of pyridoxal 5'-phosphate. We evaluated the AST/ALT ratio for the diagnosis of liver fibrosis or cirrhosis in a cohort of CHC patients included in a multicenter prospective study. A liver biopsy was performed in each patient and reviewed by two independent pathologists in order to determine the fibrosis stage according to Metavir classification which was the reference standard. AST/ALT ratio significantly increased with histological stage of liver fibrosis and there was a significant correlation between Metavir fibrosis stage and AST/ALT ratio (r=0.129, PALT ratio does not discriminate significant fibrosis (F≥2) (AUROC=0.531) and had only very poor diagnostic accuracies for severe fibrosis (F≥3) (AUROC=0.584) or cirrhosis (F4) (AUROC=0.626). AST/ALT ratio is not a good and discriminative index of liver fibrosis in CHC when aminotransferase activities are determinate according to the international recommendations.

    We investigated the clinical prognostic value of preoperative De Ritis ratio (aspartate aminotransferase [AST]/alanine aminotransferase [ALT]) on postsurgical survival outcomes in patients with upper tract urothelial cancer (UTUC). We retrospectively analyzed the data of 623 patients who underwent radical nephrouretectomy for UTUC. Multivariate regression tests were performed to identify possible associations between adverse pathologic events and AST/ALT. The risk of postoperative progression and survival were tested using Kaplan-Meier analyses and Cox proportional hazards models. According to the receiver operator characteristic curve of AST/ALT for cancer-specific mortality, patients with AST/ALT value ≥1.5 were regarded as the high AST/ALT group, and the remaining patients formed the low AST/ALT group. In Kaplan-Meier analyses, the high AST/ALT group showed worse progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (all P ALT was associated with higher T stage (hazard ratio [HR], 1.577; 95% confidence interval [CI], 1.077-2.311; P = .033) and higher cellular grade (HR, 1.538; 95% CI, 1.034-2.287; P = .041) in multivariate regression tests. In multivariate Cox analyses, high AST/ALT was revealed as an independent predictor of PFS (HR, 2.335; 95% CI, 1.633-3.340; P ALT was a significant predictor of worse postoperative survival in patients surgically treated for UTUC. Further large prospective studies are needed for better understanding of the prognostic value of preoperative AST/ALT. Copyright © 2016 Elsevier Inc. All rights reserved.

    In this research we demonstrate that a flexible ultra-thin supercapacitor can be fabricated using high volume screen printing process. This has enabled the sequential deposition of current collector, electrode, electrolyte materials and adhesive onto a Polyethylene terephthalate (PET) substrate in order to form flexible electrodes for reliable energy storage applications. The electrodes were based on an activated carbon ink and gel electrolyte each of which were formulated for this application. Supercapacitors that have surface areas from 100 to 1600 mm 2 and an assembled device thickness of 375 μm were demonstrated. The capacitance ranged from 50 to 400 mF. Capacitance of printed carbon electrodes is rarely reported in literature and no references were found. The chemistry developed during this study displayed long-term cycling potential and demonstrated the stability of the capacitor for continued usage. The gel electrolyte developed within this work showed comparable performance to that of a liquid counterpart. This improvement resulted in the reduction in gel resistance from 90Ω to 0.5Ω. Significant reduction was observed for all resistances. The solid-state supercapacitors with the gel electrolyte showed comparable performance to the supercapacitors that used a liquid electrolyte. This large area printed device can be used in future houses for reliable green energy storage. - Highlights: • It has been demonstrated that a flexible supercapacitors with large area storage has been developed. • The simplified architecture has the potential to lead to a new class of printable, thin storage devices. • The specific capacitance of 21 F/g was measured.

The three regions examined are the Paradox Basin in Utah, the Permian Basin in Texas, and the Mississippi Study Area. Additional and new data became available to ONWI during and following these analyses; therefore, this report must be considered a methodology demonstration here would apply as illustrated had the complete data sets been available. A combination of geostatistical and hydrologic analyses was used for this demonstration. Geostatistical analyses provided an optimal estimate of the potentiometric surface from the available data, a measure of the uncertainty of that estimate, and a means for selecting and evaluating the location of future data. The hydrologic analyses included the calculation of transmissivities, flow paths, travel times, and ground-water flow rates from hypothetical repository sites. Simulation techniques were used to evaluate the effect of optimally located future data on the potentiometric surface, flow lines, travel times, and flow rates. Data availability, quality, quantity, and conformance with model assumptions differed in each of the salt areas. Report highlights for the three locations are given

  9. Consultancy on 'Knowledge preservation in the area of fast reactor technology'. Working material

    International Nuclear Information System (INIS)

    2002-01-01

    The fast reactor, which can generate electricity and breed additional fissile material for future fuel stocks is a resource that will be needed when economic uranium supplies for the advanced light water reactors or other thermal-spectrum options diminish. Further, the fast-fission fuel cycle in which material is recycled offers the flexibility needed to contribute decisively towards solving the problem of growing spent fuel inventories by greatly reducing the volume of high-level waste that must be disposed of in long-term repositories. This is a waste management option that also should be retained for future generations. The fast reactor has been the subject of research and development programs in a number of countries for upwards of 40 years. Now, despite early sharing and innovative worldwide research and development, ongoing work is confined to China, India, Japan, the Republic of Korea, and Russia. Information generated worldwide will be needed in the future. Presently, it is in danger of being lost even in those countries continuing the work. Some countries have already taken the issue of knowledge preservation seriously: Japan, France, Britain, and Russia, in particular. At worst, valuable contributory information elsewhere will be lost and would have to be regenerated when needed. The IAEA initiative seeks to establish a comprehensive, international inventory of fast reactor data and knowledge, which would be sufficient to form the basis for fast reactor development in 20 to 40 years from now. The Agency is in a good position to provide the framework for knowledge preservation efforts. Under Article III of its Statute, the IAEA is mandated to encourage and assist research on, and development and practical application of atomic energy for peaceful uses throughout the world. Obviously, an important aspect of this mandate is maintaining and increasing the knowledge that is necessary for the technological development. The main objectives of the consultancy

  10. Criticality Detection Using a Mirion Technologies DRM-2NC Remote Area Monitor Geiger-Mueller Probe

    Kryskow, Adam P.

    The prompt fission neutron activation and subsequent response of a DRM-2NC Geiger-Mueller probe (manufactured by Mirion Technologies) was investigated for the purpose of creating a criticality accident detection algorithm with sensitivity and false positive suppression comparable to modern criticality accident detection systems. The expected decay pattern of secondary emissions arising from the neutron induced activity of the Geiger-Mueller probe was investigated experimentally in high neutron fluence environments at research reactors operated by the University of Massachusetts Lowell, Pennsylvania State University, and the White Sands Missile Range of Los Alamos National Laboratory. Monte Carlo techniques were used to both identify key probe materials responsible for the majority of the Geiger-Mueller response and investigate the effects of boron doping to increase detector sensitivity and enhance the signal to noise ratio. Subsequently, a statistical algorithm centered on a point weighted linear regression of the combined effective half-life was developed as the basis for criticality declaration. Final testing of the system indicated that the system was capable of meeting all ANSI criticality accident criteria with sufficient sensitivity to the minimum accident of concern, an adequate response time, and an extremely low likelihood of false alarm.

  11. Developments of large-area APD arrays for future applications to PET technology

    International Nuclear Information System (INIS)

    2010-01-01

    Silicon avalanche photodiodes (APD) are solid-state devices which have internal gain. Since the good features of both photodiodes (PDs) and photomultiplier tubes (PMTs) are shared in a single device, APD offers new design for physics experiments and devices for nuclear medicine. In particular, thanks to its high quantum efficiency (QE) and low noise, reverse-type APDs generally show much better energy resolution than traditional PMTs when coupled to various scintillators. Most recently, we have developed various large area reverse-type APDs with Hamamatsu Photonics, up to 32 x 32 mm 2 square area. Such large dimensions have been awaited by researchers world-wide, and further extend the potential of APDs for various application such as in space science and nuclear medicine. For example, the use of APDs in space experiments is now validated thanks to successful launch of the Cute 1.7+APD II, which has measured both electron/proton distributions in Low Earth Orbit at E >9 keV. Moreover, the mission successfully demonstrated an active gain control system to keep the APD gain stable under moderate temperature variations. In other aspects, an APD is a compact, high performance light sensor that could be used in the strong magnetic field MRIs. An ultimate spatial resolution as better as sub-mm will be possible by adopting small pixel, high density APD pixels. Future PET detectors with time-of-flight (TOF) capability may be expected thanks to very fast time response of the APD devices. As a first step, we have developed a versatile APD-based positron emission tomography (PET) modules for future applications in high resolution, fast medical imaging. We will also discuss future use of digital (Geiger-mode) APDs, such as multi-pixel photon counter (MPPCs) in similar medical imaging applications. (author)

  12. Space Technology for Reduction of Desert Areas on Earth and Weather Control

    Full Text Available In precedent papers the authors presented the idea of a space system composed of two opposite parabolic mirrors (large and small having the same focal point. This system is able to concentrate solar power in a strong light beam having irradiance of hundreds or thousands of times stronger than the solar irradiance on Earth's orbit. The system can be placed on a Sun synchronous orbit around the Earth or on the Earth’s orbit around the Sun at a distance of several hundred km from ground. When the concentrated light beam is directed toward the Earth surface it can locally melt, vaporize or decomposes tones of ground in its elements. This is happening because when the ground is hit by the light beam, ground temperature can reach thousands of degrees Celsius. At such temperatures the matter is decomposed into constitutive elements. For example, the silicate oxides which are frequently found in the composition of desert ground are decomposed into oxygen and silicon. Similarly, other oxides release oxygen and other type of oxides or constitutive elements. A network of deep and large channels can be dug in this way in hot deserts as Sahara. When these channels are connected with the seas & oceans, a network of water channels is created in those deserts. In this way, the local climate of deserts will change because channel water is vaporized during daytime when air temperature reaches 50ºC and condenses during nighttime when air temperature is around 0ºC. Presence of clouds over the hot deserts can lead to a reduction of ground temperature and rain follows. The channel water can be desalinized for producing drinking water and for irrigation using simple equipment. In addition to these advantages, channel deserts can be a solution for melting of polar ice calottes and flooding of seaside areas that are inhabited areas. On the other hand, the system composed of two opposite mirrors can be used for strength decreasing or deviation of hurricanes and

    Full Text Available Veracruz comes third in terms of national coffee production; however this sector is facing a crisis because of the fall in prices in the international market which has resulted amongst other things in increased emigration to the United States. The aim of this study was to analyze the relationship between migration and the level of technology employed in coffee production in two communities in the central area of Veracruz State: Capulapa and Zapoapan. Information was obtained through observation and by interviewing the members of 46 family production units (FPU. In Zapoapan, the FPUs which presented the highest level of technological management in their coffee plantations were those with greatest access to capital, as they are more extensive, produce other crops than coffee, have more family members in the United States and receive greater remittances; investing 14% more in agriculture. In the case of the FPUs in Capulapa, no relationship was observed between the number of international emigrants, the amount of remittances received and the level of technological management. This may be because 83% of the FPUs cultivate solely coffee and are beholden to the ups and downs of the international market, thus their socio-economic situation is more precarious and 86% of remittances are directed towards family sustenance; with only 7% directed towards agricultural investment.

Meanwhile, thanks to the through-silicon via (TSV, three-dimensional (3D stacking technology has emerged as a practical solution to achieving the desired requirements of a high-performance circuit. In this paper, we present the benefits of 3D stacking and process technology scaling on stereo matching processors. We implemented 2-tier 3D-stacked stereo matching processors with GlobalFoundries 130-nm and Nangate 45-nm process design kits and compare them with their two-dimensional (2D counterparts to identify comprehensive design benefits. In addition, we examine the findings from various analyses to identify the power benefits of 3D-stacked integrated circuit (IC and device technology advancements. From experiments, we observe that the proposed 3D-stacked ICs, compared to their 2D IC counterparts, obtain 43% area, 13% power, and 14% wire length reductions. In addition, we present a logic partitioning method suitable for a pipeline-based hardware architecture that minimizes the use of TSVs.

    The crustacean stomatogastric nervous system (STNS) is a well-known model for investigating neuropeptidergic control of rhythmic behavior. Among the peptides known to modulate the STNS are the C-type allatostatins (AST-Cs). In the lobster, Homarus americanus, three AST-Cs are known. Two of these, pQIRYHQCYFNPISCF (AST-C I) and GNGDGRLYWRCYFNAVSCF (AST-C III), have non-amidated C-termini, while the third, SYWKQCAFNAVSCFamide (AST-C II), is C-terminally amidated. Here, antibodies were generated against one of the non-amidated peptides (AST-C I) and against the amidated isoform (AST-C II). Specificity tests show that the AST-C I antibody cross-reacts with both AST-C I and AST-C III, but not AST-C II; the AST-C II antibody does not cross-react with either non-amidated peptide. Wholemount immunohistochemistry shows that both subclasses (non-amidated and amidated) of AST-C are distributed throughout the lobster STNS. Specifically, the antibody that cross-reacts with the two non-amidated peptides labels neuropil in the CoGs and the stomatogastric ganglion (STG), axons in the superior esophageal (son) and stomatogastric (stn) nerves, and ~ 14 somata in each commissural ganglion (CoG). The AST-C II-specific antibody labels neuropil in the CoGs, STG and at the junction of the sons and stn, axons in the sons and stn, ~ 42 somata in each CoG, and two somata in the STG. Double immunolabeling shows that, except for one soma in each CoG, the non-amidated and amidated peptides are present in distinct sets of neuronal profiles. The differential distributions of the two AST-C subclasses suggest that the two peptide groups are likely to serve different modulatory roles in the lobster STNS.

    The public acceptability of large technological developments was studied. A socio-economic baseline profile of the community was compiled in an attempt to measure the inherent ability of a community to adjust to changes brought about by large developments. The framework within which the study was conducted included the demographic composition, the economic activity, the infrastructure of the private and public sectors, the organisational composition of the community, the expectations members of the community had in respect of the possible developments, the attitudes of the community towards itself, as well as towards outsiders and finally, the degree of solidarity that exists amongst them in respect of these attitudes. With information regarding the intended developments, certain extrapolations were made in respect of possible tendencies and changes that may come about in the demographic composition of the community. In the light of these predictions certain potential future problems were identified and pre-emptive recommendations were made accordingly. Of the most important observations that can be made is the fact that the methods used were adequate to achieve a detailed baseline profile of the community, its qualities, attitudes and expectations. The detail was sufficient to enable the researcher to compare the communities living in the different residential areas. Information gathered from interviews with leading figures turned out to be a useful tool in the verification of data gathered by way of questionnaires. 71 figs., 110 tabs., 176 refs

    AST-120 (Kremezin; Kureha Chemical Industry Co Ltd, Tokyo, Japan) is an orally administered adsorbent showing adsorption ability superior to activated charcoal for certain organic compounds known to be precursors of substances that accumulate in patients with chronic kidney disease (CKD) and that are believed to accelerate the decline in kidney function. AST-120 is approved in Japan for prolonging time to hemodialysis therapy and improving uremic symptoms in patients with CKD. A multicenter, randomized, double-blind, placebo-controlled, dose-ranging study was designed to examine the nephroprotective effects of 3 doses of AST-120 versus placebo in adult patients with moderate to severe CKD and elevated serum indoxyl sulfate levels while following an adequate protein-intake diet. Eligible patients were randomly assigned to 1 of 3 doses of AST-120 (0.9, 2.1, or 3.0 g) or placebo 3 times daily for 12 weeks. AST-120 decreased serum indoxyl sulfate levels in a dose-dependent fashion. During the 12-week treatment period, AST-120 did not affect serum creatinine levels or 24-hour urine creatinine appearance. Significant improvements in malaise were observed in a dose-dependent fashion. All doses of AST-120 were well tolerated and did not adversely affect the general health status of patients. Results suggest that the dose of 3 g 3 times daily is an optimal dose for the US population, and it may be useful in the treatment of patients with CKD. Because AST-120 did not directly affect serum creatinine levels or 24-hour urine creatinine appearance, the composite end point of doubling of serum creatinine level, transplantation, and dialysis therapy would be appropriate for a confirmatory phase III therapeutic outcome study.

    The aim of this intervention study was to illuminate the meaning of ICT-based caregiver support as experienced by older family carers living in vast rural areas, caring for a spouse at home. In order to access, the support service participants were provided with a computer and high speed Internet in their homes. Semi structured webcam-interviews were carried out with 31 family carers. A strategy for webcam interviewing was developed to ensure quality and create a comfortable interview situation for the family carers. Interviews were analysed using content analyses, resulting in the themes: Adopting new technology with help from others and Regaining social inclusion . The results indicate that ICT-based support can be valuable for older family carers in rural areas as it contributes to improve quality in daily life in a number of ways. In order to fully experience the benefits, family carers need to be frequent users of the provided support. Adequate training and encouragement from others were essential in motivating family carers to use the support service. Access to Internet and webcamera contributed to reducing loneliness and isolation, strengthening relationships with relatives living far away and enabled access to services no longer available in the area. Use of the ICT-service had a positive influence on the relationship between the older carer and adult grandchildren. It also contributed to carer competence and promote feelings of regaining independence and a societal role.

    Full Text Available The majority of Ethiopia’s people (85% reside in rural areas, deriving their livelihood from agriculture. Ethiopia’s energy system is characterized mainly by biomass fuel supply, with households being the greatest energy consumers. The household sector takes up nearly 94 % of the total energy supplies. Access to energy resources and technologies in rural Ethiopia is highly constrained which makes the energy supply and consumption pattern of the country to show many elements of un-sustainability. The concern on cooking practices, household economics, health, forest and agricultural resource management, and global greenhouse gas emissions has emerged as a transformative opportunity to improve individual lives, livelihoods, and the global environment. More decentralized renewable energy projects could play an important role in mitigating traditional biomass fuel use. Improved cooking stove (ICS dissemination projects have been launched involving the private sector in the production and commercialization of the stoves. In doing so, about 3.7 million ICSs have been disseminated in the country so far which benefited stove users, producers and the total environment as about 30 million hectare of forest per year can be conserved. Conversion of animal waste to biogas energy to replace traditional fuel and use of the slurry as a fertilizer is the other current focus of the government of Ethiopia and installed more than 860 biogas digesters. The benefits obtained from these technologies are considerable and promising. However, the programs are not that much benefited the rural households where it had been intended to address. So, due attention should be given for those of the rural households in order to address the fuel wood crisis, environmental degradation and their health condition.

    We demonstrate amplification experiments using a very large mode area Yb-doped double-clad fiber with 100 µm aluminum-cer codoped core and 440 µm pump cladding realized by high aluminum codoping. The material for core and pump cladding was fabricated by reactive powder sinter technology. A high numerical aperture (NA) of the pump cladding with NA = 0.21 and a low one of the core with NA = 0.084 could be realized. Using a 0.55 m short fiber sample as the main amplifier in a three-stage ns pulsed fiber master oscillator power amplifier system we achieved 3 ns, 2 mJ output pulses with 360 kW peak power limited by the available pump power. Stimulated Raman scattering effects and amplified spontaneous emission were successfully suppressed. (letter)

    Noninvasive tests are primarily used for staging hepatic fibrosis in patients with chronic liver disease. In clinical practice, serum aminotransferase levels, coagulation parameters, and platelet count have been used to predict whether or not a patient has cirrhosis. In addition, several studies have evaluated the accuracy of combinations (or ratios) of these measures. The present study aimed to investigate the relationship between five noninvasive models [AST/ALT ratio (AAR), aspartate aminotransferase to platelet ratio index (APRI), Bonacini cirrhosis discriminant score (CDS), age-platelet index (APind), and King's score] and the degree of hepatic fibrosis as determined by biopsy in patients with chronic hepatitis B and C. A total of 380 patients with viral hepatitis (237 with chronic hepatitis B and 143 with chronic hepatitis C) who were seen at our clinic between January 2005 and January 2011 were retrospectively analyzed. The degree of fibrosis was determined using the Ishak score. Patients with a fibrosis score of 0-2 were considered to have low fibrosis and those with a score between 3 and 6 were considered to have high fibrosis. Five noninvasive models were compared between the groups with low and high fibrosis. There were statistically significant differences between the hepatitis B and C patients with high and low fibrosis with respect to APind (4.49±2.35 vs. 2.41±1.84; P<0.001 in hepatitis B and 4.83±2.25 vs. 2.92±1.88; P<0.001 in hepatitis C), APRI (1.00±1.17 vs. 0.47±0.39; P<0.001 in hepatitis B and 1.01±1.01 vs. 0.41±0.29; P<0.001 in hepatitis C), CDS (4.53±1.90 vs. 3.58±1.30; P<0.001 in hepatitis B and 4.71±2.03 vs. 3.42±1.49; P<0.05 in hepatitis C), and King's score (24.31±3.14 vs. 7.65±6.70; P<0.001 in hepatitis B and 24.82±2.55 vs. 8.33±7.29; P<0.001 in hepatitis C). There were no significant differences in the AAR between the hepatitis B and C patients with high and low fibrosis (0.78±0.31 vs. 0.74±0.34; P=0.082 in hepatitis B

    Climate change is widely considered one of the greatest challenges to global sustainability, with extreme events being the most immediate way that people experience this phenomenon. Urban areas are particularly vulnerable to these events given their location, concentration of people, and increasingly complex and interdependent infrastructure. We are developing a conceptual framework for urban social-ecological-technological systems (SETS) that will allow researchers and practitioners to assess how infrastructure can be resilient, provide ecosystem services, improve social well being, and exploit new technologies in ways that benefit urban populations. The framework integrates the three domains of social and equity issues, environmental quality and protection, and technical/engineering aspects, to form a concept of infrastructure that occurs at the intersection of the domains. Examples show how the more common socioecological systems and socially sensitive engineering approaches that fail to incorporate the third dimension may elevate vulnerability to climate-related disaster. The SETS conceptual framework bridges currently siloed social science, environmental science, and engineering approaches to significantly advance research into the structure, function, and emergent properties of SETS. Extreme events like heat waves in Phoenix; coastal and urban flooding in the wake of superstorm Sandy and following hurricanes in Miami, FL; drought in Mexico; and urban flooding in Baltimore, Portland, San Juan PR, Syracuse, and Valdivia, Chile provide examples of the impacts of and vulnerability to extreme events that demand a new approach. The infrastructure of the future must be resilient, leverage ecosystem services, improve social well being, and exploit new technologies in ways that benefit all segments of urban populations and are appropriate to the particular urban contexts. These contexts are defined not only by the biophysical environment but also by culture and

    With the continuous and enormous spread of mobile technologies, mHealth has evolved as a new subfield of eHealth. While eHealth is broadly focused on information and communication technologies, mHealth seeks to explore more into mobile devices and wireless communication. Since mobile phone penetration has exceeded other infrastructure in low and middle-income countries (LMICs), mHealth is seen as a promising component to provide pervasive and patient-centered care. The aim of our research work for this paper is to examine the mHealth literature to identify application areas, target diseases, and mHealth service and technology types that are most appropriate for LMICs. Based on the 2011 WHO mHealth report, a combination of search terms, all including the word "mHealth", was identified. A literature review was conducted by searching the PubMed and IEEE Xplore databases. Articles were included if they were published in English, covered an mHealth solution/ intervention, involved the use of a mobile communication device, and included a pilot evaluation study. Articles were excluded if they did not provide sufficient detail on the solution covered or did not focus on clinical efficacy/effectiveness. Cross-referencing was also performed on included articles. 842 articles were retrieved and analyzed, 255 of which met the inclusion criteria. North America had the highest number of applications (n=74) followed by Europe (n=50), Asia (n=44), Africa (n=25), and Australia (n=9). The Middle East (n=5) and South America (n=3) had the least number of studies. The majority of solutions addressed diabetes (n=51), obesity (n=25), CVDs (n=24), HIV (n=18), mental health (n=16), health behaviors (n=16), and maternal and child's health (MCH) (n=11). Fewer solutions addressed asthma (n=7), cancer (n=5), family health planning (n=5), TB (n=3), malaria (n=2), chronic obtrusive pulmonary disease (COPD) (n=2), vision care (n=2), and dermatology (n=2).

    Full Text Available With the development of modern society, the scale of the power system is rapidly increased accordingly, and the framework and mode of running of power systems are trending towards more complexity. It is nowadays much more important for the dispatchers to know exactly the state parameters of the power network through state estimation. This paper proposes a robust power system WLS state estimation method integrating a wide-area measurement system (WAMS and SCADA technology, incorporating phasor measurements and the results of the traditional state estimator in a post-processing estimator, which greatly reduces the scale of the non-linear estimation problem as well as the number of iterations and the processing time per iteration. This paper firstly analyzes the wide-area state estimation model in detail, then according to the issue that least squares does not account for bad data and outliers, the paper proposes a robust weighted least squares (WLS method that combines a robust estimation principle with least squares by equivalent weight. The performance assessment is discussed through setting up mathematical models of the distribution network. The effectiveness of the proposed method was proved to be accurate and reliable by simulations and experiments.

    In China, local governments of many areas prefer to give priority to the development of heavy industrial clusters in pursuit of high value of gross domestic production (GDP) growth to get political achievements, which usually results in higher costs from ecological degradation and environmental pollution. Therefore, effective methods and reasonable evaluation system are urgently needed to evaluate the overall efficiency of industrial clusters. Emergy methods links economic and ecological systems together, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. This method has been successfully applied in many case studies of ecosystem but seldom in industrial clusters. This study applied the methodology of emergy analysis to perform the efficiency of industrial clusters through a series of emergy-based indices as well as the proposed indicators. A case study of Shenyang Economic Technological Development Area (SETDA) was investigated to show the emergy method's practical potential to evaluate industrial clusters to inform environmental policy making. The results of our study showed that the industrial cluster of electric equipment and electronic manufacturing produced the most economic value and had the highest efficiency of energy utilization among the four industrial clusters. However, the sustainability index of the industrial cluster of food and beverage processing was better than the other industrial clusters.

    Rangelia vitalii is a protozoon that causes diseases in dogs, and anemia is the most common laboratory finding. However, few studies on the biochemical changes in dogs infected with this protozoon exist. Thus, this study aimed to investigate the biochemical changes in dogs experimentally infected with R. vitalii, during the acute phase of the infection. For this study, 12 female dogs (aged 6-12 months and weighing between 4 and 7 kg) were used, divided in two groups. Group A was composed of healthy dogs (n = 5); and group B consisted of infected animals (n = 7). Blood samples were collected on days 0, 10, 20 and 30 after infection, using tubes without anticoagulant to obtain serum and analyze the biochemical parameters. An increase in alanine aminotransferase (ALT) on day 20 (P < 0.05) was observed. Also, increased creatine kinase (CK) and aspartate aminotransferase (AST) levels were observed throughout the experimental period (P < 0.05). No changes in the serum gamma-glutamyltransferase, urea and creatinine levels were observed. Thus, is possible to conclude that experimental infection with R. vitalii in dogs causes changes to the biochemical profile, with increased ALT, AST and CK enzyme levels.

    Objective: To analyze the changes and relationship of early hemodynamic indexes of patients with large area burns monitored by pulse contour cardiac output (PiCCO) monitoring technology, so as to assess the guiding value of this technology in the treatment of patients with large area burns during shock period. Methods: Eighteen patients with large area burns, confirming to the study criteria, were admitted to our unit from May 2016 to May 2017. Pulse contour cardiac output index (PCCI), systemic vascular resistance index (SVRI), global end-diastolic volume index (GEDVI), and extravascular lung water index (EVLWI) of patients were monitored by PiCCO instrument from admission to post injury day (PID) 7, and they were calibrated and recorded once every four hours. The fluid infusion coefficients of patients at the first and second 24 hours post injury were calculated. The blood lactic acid values of patients from PID 1 to 7 were also recorded. The correlations among PCCI, SVRI, and GEDVI as well as the correlation between SVRI and blood lactic acid of these 18 patients were analyzed. Prognosis of patients were recorded. Data were processed with one-way analysis of variance, single sample t test and Bonferroni correction, Pearson correlation analysis, and Spearman rank correlation analysis. Results: (1) There was statistically significant difference in PCCI value of patients from post injury hour (PIH) 4 to 168 ( F =7.428, P 0.05). (2) There was statistically significant difference in SVRI value of patients from PIH 4 to 168 ( F =7.863, P 0.05). (3) There was no statistically significant difference in the GEDVI values of patients from PIH 4 to 168 ( F =0.704, P >0.05). The GEDVI values of patients at PIH 8, 12, 16, 20, and 24 were significantly lower than normal value ( t =-3.112, -3.554, -2.969, -2.450, -2.476, P 0.05). (4) There was statistically significant difference in EVLWI value of patients from PIH 4 to 168 ( F =1.859, P 0.05). (5) The fluid infusion

    Current laboratory monitoring may not be optimal. A retrospective chart review was performed on thelaboratory results of 246 patients who were treated with isotretinoin for acne over a 9-year period. Tests obtained were CBC, lipid panel, AST, ALT, CK, GGT,and C-reactive protein. Thirty-five patients had an elevated AST and 35 of these had an elevated CK; 32 had an elevated ALT and 11 of these had an elevated CK. Thirteen patients had an elevated GGT; in 5 this was the only abnormality, whereas 8 had a GGT elevation accompanied by an elevated AST or ALT. Two had an elevated GGT and an elevated CK with normal AST and ALT. Fifty-two patients had a single episode of elevated CK, of which 22 were female. However, 57 had multiple CK elevations and only one was female. Thirty-five patients had CK elevations <2 times normal; 38 had levels between 2 and 3 times normal, 18 had levels between 3 and 4 times normal, and 18 had levels greater than 4 times normal. We suggest that ALT and AST are not useful for monitoring isotretinoin therapy and that GGT and CK may be of greater value in managing patients.

    In the near term NASA is entering into the peak activity period of the Earth Observing System (EOS). The EOS AM-1 /"Terra" spacecraft is nearing launch and operation to be followed soon by the New Millennium Program (NMP) Earth Observing (EO-1) mission. Other missions related to land imaging and studies include EOS PM-1 mission, the Earth System Sciences Program (ESSP) Vegetation Canopy Lidar (VCL) mission, the EOS/IceSat mission. These missions involve clear advances in technologies and observational capability including improvements in multispectral imaging and other observing strategies, for example, "formation flying". Plans are underway to define the next era of EOS missions, commonly called "EOS Follow-on" or EOS II. The programmatic planning includes concepts that represent advances over the present Landsat-7 mission that concomitantly recognize the advances being made in land imaging within the private sector. The National Polar Orbiting Environmental Satellite Series (NPOESS) Preparatory Project (NPP) is an effort that will help to transition EOS medium resolution (herein meaning spatial resolutions near 500 meters), multispectral measurement capabilities such as represented by the EOS Moderate Resolution Imaging Spectroradiometer (MODIS) into the NPOESS operational series of satellites. Developments in Synthetic Aperture Radar (SAR) and passive microwave land observing capabilities are also proceeding. Beyond these efforts the Earth Science Enterprise Technology Strategy is embarking efforts to advance technologies in several basic areas: instruments, flight systems and operational capability, and information systems. In the case of instruments architectures will be examined that offer significant reductions in mass, volume, power and observational flexibility. For flight systems and operational capability, formation flying including calibration and data fusion, systems operation autonomy, and mechanical and electronic innovations that can reduce

    By using 1985, 1995, 1997, 2000 and 2004 satellite images and GIS technology, three indices including built-up area density, expansion intensity index, and fractal dimension were chosen to analyze the spatiotemporal characteristics, spatial differentiation, and morphological changes of urban and rural built-up areas in Shenyang City in 1985-2004, with the main driving factors discussed. In the study period, the high-density area of urban built-up area in the City increased year by year, and that of rural built-up area changed slightly before 1997 but increased gradually thereafter. The increased area, expansion speed, and expansion intensity of built-up area were evidently greater in urban than in rural area. An obvious spatial differentiation was observed in the expansion of built-up area between urban and rural areas, with the high-speed expansion mainly concentrated in urban area. The fractal dimension in urban area increased gradually, which meant that the integrated configuration of urban area became more and more complex, while that in rural area changed irregularly, because of the lack of reasonable planning and construction. Economic development, population growth, transportation, natural environment, policy-guiding, and urban planning were the main driving forces of the expansion of built-up areas in Shenyang City.

    The Environmental Restoration (ER) Project has been tasked with the characterization, assessment, remediation and long-term monitoring of contaminated waste sites at Sandia National Laboratories/New Mexico (SNL/NM). Many of these sites will require remediation which will involve the use of baseline technologies, innovative technologies that are currently under development, and new methods which will be developed in the near future. The Technology Applications Program (TAP) supports the ER Project and is responsible for development of new technologies for use at the contaminated waste sites, including technologies that will be used for remediation and restoration of these sites. The purpose of this report is to define the remediation needs of the ER Project and to identify those remediation needs for which the baseline technologies and the current development efforts are inadequate. The area between the remediation needs and the existing baseline/innovative technology base represents a technology gap which must be filled in order to remediate contaminated waste sites at SNL/NM economically and efficiently. In the first part of this report, the remediation needs of the ER Project are defined by both the ER Project task leaders and by TAP personnel. The next section outlines the baseline technologies, including EPA defined Best Demonstrated Available Technologies (BDATs), that are applicable at SNL/NM ER sites. This is followed by recommendations of innovative technologies that are currently being developed that may also be applicable at SNL/NM ER sites. Finally, the gap between the existing baseline/innovative technology base and the remediation needs is identified. This technology gap will help define the future direction of technology development for the ER Project

    AST-type zeolite with a plate morphology can be synthesized by topotactic conversion of a layered silicate (β-helix-layered silicate; HLS) by using N,N-dimethylpropionamide (DPA) to control the layer stacking of silicate layers and the subsequent interlayer condensation. Treatment of HLS twice with 1) hydrochloric acid/ethanol and 2) dimethylsulfoxide (DMSO) are needed to remove interlayer hydrated Na ions and tetramethylammonium (TMA) ions in intralayer cup-like cavities (intracavity TMA ions), both of which are introduced during the preparation of HLS. The utilization of an amide molecule is effective for the control of the stacking sequence of silicate layers. This method could be applicable to various layered silicates that cannot be topotactically converted into three-dimensional networks by simple interlayer condensation by judicious choice of amide molecules.

    2002-10-01

    The development and severity of liver fibrosis in patients with chronic HCV infection can be evaluated best according to the staging of fibrosis in blind liver biopsy. So far there is however no biochemical indicator suggesting advanced fibrosis or progression of fibrosis in chronic HCV infection. In 1997 - 1999 60 adult out-patients (32 women) with chronic HCV infection were examined by blind liver biopsy. The grading of hepatitis was scored according to Knodell and staging of fibrosis according to Desmet. All patients were anti-HCV positive, assessed by the ELISA-3 method and 48/60 had positive HCV RNA in serum. The main risk factor of HCV infection was blood transfusion (67%). Of 27 examined patients 20 (74%) had serotype HCV 1. Staging of fibrosis: histologically confirmed fibrosis was not recorded in 11 patients (18.3%), mild and medium fibrosis was recorded in 25 (42%), severe fibrosis in 14 (23%) and cirrhosis in 10 (17%). With confirmed fibrosis correlated more closely AST serum activity (p < 0.002) than ALT activity (p < 0.03). Steatosis of the liver was found in 25 (42%) patients. The mean age of patients with steatosis was significantly higher than that of patients without steatosis (p < 0.0008). Steatosis was more frequent in patients with fibrosis (p < 0.04), in particularin the age group above 60 years. The development of fibrosis in patients with chronic HCV infection is suggested by permanently elevated activity of both transaminases whereby AST has a higher predictive value than ALT activity. A total of 40% histologically tested patients had the highest staging of fibrosis (3 - 4). Steatosis is in chronic HCV infection a very frequent finding (42%), in particular in patients above 60 years and those with serious fibrosis. The finding of fibrosis should stimulate the initiation of antiviral treatment which can lead to regression of fibrosis and improvement of the histological finding.

  15. AST to ALT Ratio is elevated in disseminated histoplasmosis as compared to localized pulmonary disease and other endemic mycoses.

    2017-07-01

    Severe pulmonary or disseminated histoplasmosis often necessitates presumptive antifungal treatment while awaiting definitive diagnosis. Histoplasma antigen assays have improved sensitivity but results may lag up to 7 days. In order to increase diagnostic certainty, "soft clues" may be looked for in laboratory and radiologic data, such as elevated alkaline phosphatase or ferritin levels and findings of mediastinal adenopathy or hepatosplenomegaly. To determine if elevated aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio is specific to histoplasmosis or a non-specific marker for disseminated fungal infection or sepsis in general, we retrospectively examined records of all patients diagnosed with an endemic fungal infection (EFI) at Rush University Medical Center from January of 1997 to October of 2012, and a cohort of septic patients with elevated liver enzymes. We identified 90 cases of EFIs during the study period that met all inclusion criteria (Histoplasma 21, Blastomyces 56, Coccidioides 12, Paracoccidioides 1). We also evaluated 10 control patients with bacterial sepsis. The mean ratio of AST to ALT in patients with disseminated histoplasmosis was 2.69 (95% CI:1.22, 4.16) while for other EFIs, the mean ratio ranged from 0.38 to 1.14 with disseminated coccidioidomycosis and blastomycosis respectively (P histoplasmosis in the appropriate host, and to possibly distinguish cross reactivity of the Histoplasma antigen assay with other EFIs. © The Author 2016.

    Full Text Available The subject of the contribution is the evaluation of the influence of the conventional tillage and reduced tillage technology of soil processing on the infiltration properties of the soil in the Větřkovice area. Field experimental work at the area was carried out in the years 2013–2015 on Cambisol district medium-heavy clayey soil. The research was conducted on sloping erosion-endangered blocks of arable land sown with spring barley. The areas were chosen each year in the way that one of the experimental areas was handled by conventional tillage technologies and the other by reduced tillage technologies. Intact soil samples were taken into Kopecký’s cylinders in the three landscape positions, at a depth of 10 cm (representing topsoil and 30 cm (representing subsoil. The cumulative infiltration was measured using a mini-disc infiltrometer near the consumption points. The Zhang method (1997, which provides an estimate of the unsaturated hydraulic conductivity K(h, was used for the evaluation of the infiltration tests of the mini-disc infiltrometer. The soil profile processed by conventional tillage showed a higher degree of compaction. The bulk density was between 1.10–1.67 g.cm-3, compared to the land processed by the reduced tillage technology, where the values were between 0.80–1.29 g.cm-3. Unsaturated hydraulic conductivity values were about one‑third higher within the reduced tillage technology soil processing.

    Alcoholic liver disease is one of the most frequently diagnosed liver problems in the hospitalized patients in most tertiary care hospitals all over the world .The diagnosis of alcoholic liver disease is most of the time clinical. The AST/ALT ratio is a useful and reliable biochemical marker of liver injury due to alcohol. Whether the value of AST/ALT ratio correlates with clinical severity has not been studied. To study values of AST/ALT ratio in correlation with clinical severity of illness due to alcoholic liver disease using Child-Pugh's grading. This is a retrospective study. Inpatient records of all the patients admitted with diagnosis of alcoholic liver disease from July 2009 to 2011 June were analyzed. Data from 174 patients with the diagnosis of alcoholic liver disease-alcoholic hepatitis or alcoholic cirrhosis were retrieved; out of 174 patients, 138 were eligible for the study. The AST/ALT ratio and Child's grading of all the patients were calculated from the documented biochemical and clinical parameters on admission. Demographic profiles of all the patients were also recorded and analyzed. The data was analyzed using software SPPSS 16 version. A total of 138 patients diagnosed as alcoholic liver disease since July 2009 to June 2011 were analyzed. The male-female ratio was found to be 5.34: 1.The mean age of the patients at diagnosis was found to be 47.58 ± 12.83 years. Among 138 patients, Mongolians were found to have the highest prevalence of alcoholic liver disease (38.8%), followed by Newars ( 33.6%), Brahmin and Chhetri (19.1%) and Dalit (7.2%). With respect to AST/ALT ratio and Child's grading of ALD, the mean AST/ALT ratio was found to be 3.03 ± 2.24 in those patients who had Chlild's grade C; likewise the mean AST/ALT ratio was 2.28 ± 1.14, and 1.68 ± 0.83 in patients with Child B and Child A respectively. The higher value of AST/ALT ratio is indicative of more severe liver damage due to alcohol.

    We used three different methods Terrestrial Laser Scanner (TLS), terrestrial Structure from Motion photogrammetry (SfM) and aerial SfM photogrammetry with an Unmanned Aerial Vehicle (UAV) to analyse geomorphological processes in a semiarid badland landscape. Los Aguarales badlands, located in the Ebro Depression (Spain), occur in the Holocene sediment accumulated in a wide valley infilled with silt and clay. The morphology of Los Aguarales badlands is complex, making the geomorphological interpretation a difficult task. Los Aguarales badlands are characterized by the sequence of incision and piping processes developing an abrupt and complex landscape. Three different representative and small study sites were selected to carry out a detailed analysis of the geomorphological processes. Moreover, the capability of the three methods to produce high resolution point clouds was evaluated. The obtained topographical changes were very low during the first 6 months (March-October 2016). Measured topographical changes, with TLS and terrestrial SfM, were very low, and these values fall within the range of the acquisition error of the devices used (2-6 cm). The preliminary results indicated the possibilities of a multiscale approach using new technologies to study geomorphological and erosion processes, although long-term studies will be necessary to obtain erosion rates in this semiarid badland area.

    Aminotransaminases, which are strongly involved in cellular metabolism and cancer cell turnover, represent easily measureable, potential blood based biomarkers. We evaluated the prognostic value of the preoperatively assessed AST/ALT (De Ritis) ratio on clinically meaningful end points in a large European cohort of patients with nonmetastatic renal cell carcinoma. We retrospectively evaluated clinicopathological data on 698 patients with nonmetastatic renal cell carcinoma operated on between 2005 and 2013 at a single tertiary academic center. The potential prognostic value of the AST/ALT ratio was analyzed using the Kaplan-Meier method, and univariate and multivariate Cox proportional regression models. The impact of the ratio on the predictive accuracy of the Leibovich prognosis score was determined by the Harrell c-index. An increased (1.26 or greater) preoperative AST/ALT ratio was statistically significantly associated with several well established prognostic factors, including pathological T stage, as well as with histological tumor necrosis (p ALT ratio was an independent prognostic factor for metastasis-free survival (HR 1.61, 95% CI 1.25-2.07, p ALT was added. In our study cohort with nonmetastatic renal cell carcinoma the preoperatively assessed AST/ALT ratio represented an independent prognostic factor. This ratio might further improve the predictive accuracy of well established prognosis scores. Copyright © 2015 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    This qualitative study formed part of a large-scale, multi-phase study into the delivery of therapy services to people with a disability, living in one rural area of New South Wales, Australia. The study's purpose was to identify the impact of Information and Communication Technology on the workforce practices of occupational therapists' working in a rural area of New South Wales. Individual semi-structured telephone interviews were conducted with 13 occupational therapists working in disability, health and private practice in a rural area of New South Wales. Participants were asked about access to, skills and limitations of using Information and Communication Technology. A modified grounded theory approach, based on thematic analysis and constant comparison, was used to analyse the interview transcripts. This study found widespread use of technology by rurally based occupational therapists working in the disability sector in New South Wales. However, Information and Communication Technology was primarily used for client contact, professional development and professional networking rather than therapy provision. The study identified individual, workplace and community barriers to greater uptake of Information and Communication Technology by this group. The individual barriers included: age cohort, knowledge and personal preferences. The workplace barriers included: support and training and availability of resources. The community barriers included: infrastructure and perceptions of clients' acceptance. The potential exists for Information and Communication Technology to supplement face-to-face therapy provision, enhance access to professional development and reduce professional isolation thereby addressing the rural challenges of large distances, travel times and geographic isolation. To overcome these challenges, individual, workplace and community Information and Communication Technology barriers should be addressed concurrently. © 2012 The Authors Australian

    2016-03-01

    Full Text Available The article is a reflection of how the work by Maria Komornicka (pen name Piotr Odmieniec Włast was perceived in the past two decades on the basis of an analysis of a monograph by Edward Boniecki (1996, Izabela Filipiak (2006 and Brigitta Helbig-Mischewski (2010 in the context of changes in the interpretation of modern Polish literature. In the article, attention is drawn to three groups of issues which can only be identified on the basis of contemporary perception, incomplete as it is, due to the fact that all the works of Komornicka have not been published. The forms and meaning of broadly defined autobiographical writing has been re-defined, while Polish and regional literary modernism has been revised together with the involvement of literary researchers in the subject of their analyses. The author of the article suggests a schematic differentiation between updating, prospective and retrospective strategies in Komornicka’s work and a reflection on the indirect involvement in social and cultural discourses and discussions developed by contemporary researchers into Komornicka’s work.

    2012-12-01

    Full Text Available This paper is aimed to analyze the use of remediation technologies for areas contaminated with organochlorine based on a literature review and discussions with specialists. The remediation technologies analyzed were bioremediation, phytoremediation, nanotechnology, chemical oxidation, and thermal desorption. The purpose is to identify and compare “key problems” for each of these technologies envisaging the use of one or more of these them f or the remediation of the Capua Street site in Santo André, SP. Four databases were used in the preliminary literature review: Scopus, SciELO, Web of Science, and Science Direct. A survey questionnaire was designed to gather information on publications of scientific papers and patents, specific uses of these technologies by companies, and cases of application. Since the quality of the data and information obtained from this questionnaire application was not satisfactory, a new research approach for complementing them was undertaken. For this purpose, the Web of Science was selected as the most adequate data basis to carry out this second survey. However, it was realized that even for this database - that is reference for evaluating academic institutions, researchers and maturity of technologies – bias coming from the original data source can affect the survey results. Moreover, as the number of keywords used in the research consisted of generic terms for each technology, it can also be assumed that if some authors have used very specific terms, a small amount of work published by them would possibly have been misrepresented in the final result.

    Full Text Available Racional - A esteatohepatite não-alcoólica e a doença hepática alcoólica apresentam similaridade histológica e em algumas situações, o diagnóstico diferencial das mesmas pode ser difícil, pois alguns pacientes não revelam o consumo abusivo de álcool. Objetivo- Avaliar a utilidade da determinação do índice AST/ALT no diagnóstico diferencial da esteatohepatite não-alcoólica e da doença hepática alcoólica. Pacientes e Métodos -Foram estudados 29 pacientes obesos com esteatohepatite não-alcoólica, cujo o diagnóstico foi realizado após exclusão de outras causas de doença hepática e que na biopsia apresentasse, no mínimo, esteatose macrovesicular associada a infiltrado inflamatório lobular e injúria hepatocelular. Como grupo controle, foram estudados 28 pacientes com doença hepática alcoólica. Resultados - Nos pacientes com esteatohepatite não-alcoólica, a média de AST foi de 52,3 ± 21,2 U/L e a de ALT de 90,1 ± 37,9 U/L, sendo o índice AST/ALT menor que 1 em todos os casos. No grupo controle, a média de AST foi de 140 ± 82,5 U/L e a de ALT foi de 50,6 ± 40,3 U/L. O índice AST/ALT foi superior a 1 em todos os pacientes e a 2 em 24 (85,7%, o que foi estatisticamente significativo quando comparado aos pacientes com esteatohepatite não-alcoólica. Conclusão- O índice AST/ALT parece ser útil no diagnóstico diferencial das hepatopatias, sendo que valores inferiores a 1 sugerem fortemente a hipótese de esteatohepatite não-alcoólica.

    This study aims to explore the rule of changes in serum GGT activity, as well as GGT/ALT and AST/ALT ratios, in primary hepatic carcinoma (PHC) patients with different alpha-fetal protein (AFP) levels. GGT, AST and ALT were detected in 370 PHC patients with positive HBs-Ag using a automatic biochemical analyzer, and AFP was detected using a Roche E170 modular analytics immunoassay analyzer. GGT level, as well as AST/ALT and GGT/ALT, ratios were compared among PHC patients with different AFP levels. As shown in Table 1, GGT levels were 109.59 ± 111.06, 151.13 ± 190.43, 135.86 ± 107.62, 151.36 ± 176.59 and 172.58 ± 188.84, respectively, in the groups of primary PHC patients with AFP levels of ⩽ 10, 10-100, 100-200, 200-400 and ⩾ 400 ng/ml; and the differences among these groups were not statistically significant (P> 0.05). AST/ALT ratios were 1.55 ± 1.02, 1.30 ± 0.81, 2.02 ± 1.89, 2.12 ± 1.11 and 1.73 ± 1.25, respectively; and the differences among these groups were not statistically significant (P> 0.05). GGT/ALT ratios were 3.43 ± 3.12, 3.57 ± 5.70, 3.57 ± 2.94, 3.89 ± 4.58 and 3.43 ± 3.61, respectively; and the differences among these groups were not statistically significant (P> 0.05). For patients with chronic hepatitis B and cirrhosis after hepatitis B, no matter how AFP level is, when liver function report reveals increased GGT, AST/ALT > 1 and GGT/ALT > 1 (that is, AST > ALT and GGT > ALT), even if AFP is negative, we should also be alert to the existence of PHC.

  16. Using Remote Sensing Technology on the Delimitation of the Conservation Area for the Jianan Irrigation System Cultural Landsccape

    Directory of Open Access Journals (Sweden)

    C. H. Wang

    2015-08-01

    Full Text Available In recent years the cultural landscape has become an important issue for cultural heritages throughout the world. It represents the "combined works of nature and of man" designated in Article 1 of the World Heritage Convention. When a landscape has a cultural heritage value, important features should be marked and mapped through the delimitation of a conservation area, which may be essential for further conservation work. However, a cultural landscape’s spatial area is usually wider than the ordinary architectural type of cultural heritage, since various elements and impact factors, forming the cultural landscape’s character, lie within a wide geographic area. It is argued that the conservation of a cultural landscape may be influenced by the delimitation of the conservation area, the corresponding land management measures, the limits and encouragements. The Jianan Irrigation System, an historical cultural landscape in southern Taiwan, was registered as a living cultural heritage site in 2009. However, the system’s conservation should not be limited to just only the reservoir or canals, but expanded to irrigated areas where farmland may be the most relevant. Through the analysis process, only approximately 42,000 hectares was defined as a conservation area, but closely related to agricultural plantations and irrigated by the system. This is only half of the 1977 irrigated area due to urban sprawl and continuous industrial expansion.

    2011-05-01

    This research analyzes the relationship between hospital use of automated surveillance technology (AST) for identification and control of hospital-acquired infections (HAI) and implementation of evidence-based infection control practices. Our hypothesis is that hospitals that use AST have made more progress implementing infection control practices than hospitals that rely on manual surveillance. A survey of all acute general care hospitals in California was conducted from October 2008 through January 2009. A structured computer-assisted telephone interview was conducted with the quality director of each hospital. The final sample includes 241 general acute care hospitals (response rate, 83%). Approximately one third (32.4%) of California's hospitals use AST for monitoring HAI. Adoption of AST is statistically significant and positively associated with the depth of implementation of evidence-based practices for methicillin-resistant Staphylococcus aureus and ventilator-associated pneumonia and adoption of contact precautions and surgical care infection practices. Use of AST is also statistically significantly associated with the breadth of hospital implementation of evidence-based practices across all 5 targeted HAI. Our findings suggest that hospitals using AST can achieve greater depth and breadth in implementing evidenced-based infection control practices.

    Patellofemoral pain (PFP) is often reported as a diffuse pain at the front of the knee during knee-loading activities. A patient's description of pain location and distribution is commonly drawn on paper by clinicians, which is difficult to quantify, report and compare within and between patients. One way of overcoming these potential limitations is to have the patient draw their pain regions using digital platforms, such as personal computer tablets. To assess the validity of using computer tablets to acquire a patient's knee pain drawings as compared to paper-based records in patients with PFP. Patients ( N = 35) completed knee pain drawings on identical images (size and colour) of the knee as displayed on paper and a computer tablet. Pain area expressed as pixel density, was calculated as a percentage of the total drawable area for paper and digital records. Bland-Altman plots, intraclass correlation coefficient (ICC), Pearson's correlation coefficients and one-sample tests were used in data analysis. No significant difference in pain area was found between the paper and digital records of mapping pain area ( p = 0.98), with the mean difference = 0.002% (95% CI [-0.159-0.157%]). A very high agreement in pain area between paper and digital pain drawings (ICC = 0.966 (95% CI [0.93-0.98], F = 28.834, df = 31, p digital drawings. Pain drawings as acquired using paper and computer tablet are equivalent in terms of total area of reported knee pain. The advantages of digital recording platforms, such as quantification and reporting of pain area, could be realized in both research and clinical settings.

    We aimed to evaluate prognostic significance of preoperatively assessed aspartate aminotransaminase (AST)/alanine aminotransferase (ALT) (De Ritis) ratio on survival in bladder cancer (BC) patients underwent radical cystectomy (RC). We, respectively, analysed clinical and pathological data of 153 patients who underwent RC for BC between February 2006 and December 2016 at a tertiary level hospital. The potential prognostic value of De Ritis ratio was assessed by using ROC curve analysis. The effect of the De Ritis ratio was analysed by the Kaplan-Meier method and Cox regression hazard models for patients' disease-specific survival (DSS) and overall survival (OAS). We had 149 BC patients, in total. Mean age was 61.65 ± 9.13 years. One hundred and thirty-nine (93.3%) of the patients were men. According to ROC analysis, optimal threshold of De Ritis ratio for DSS was 1.30. In Kaplan-Meier analyses, the high De Ritis ratio group showed worse progression in DSS and OAS (all parameters, p < 0.001). On Cox regression models of clinical and pathological parameters to predict DSS, De Ritis ratio (HR 5.79, 95% CI 2.25-15.13), pathological T stage (HR 15.89, 95% CI 3.92-64.33, in all p < 0.001); and to predict OAS, De Ritis ratio (HR 2.61, 95% CI 1.49-4.56; p < 0.001), pathological T stage (HR 5.42, 95% CI 2.63-11.64; p < 0.001) and age (HR 1.05, 95% CI 1.02-1.08; p = 0.001) were determined as independent prognostic factors. Preoperative elevated De Ritis ratio could be an independent prognostic factor in BC patients underwent RC. Our results should be confirmed by large and properly designed prospective, randomized trials.

    Microsomal triglyceride transfer protein (MTP) is a target to reduce plasma lipids because of its indispensable role in triglyceride-rich lipoprotein biosynthesis. MTP inhibition in Western diet fed mice decreased plasma triglycerides/cholesterol, whereas increasing plasma alanine/aspartate aminotransferases (ALT/AST) and hepatic triglycerides/free cholesterol. Free cholesterol accumulated in the endoplasmic reticulum (ER) and mitochondria resulting in ER and oxidative stresses. Mechanistic studies revealed that MTP inhibition increased transcription of the GPT/GOT1 genes through up-regulation of the IRE1α/cJun pathway leading to increased synthesis and release of ALT1/AST1. Thus, transcriptional up-regulation of GPT/GOT1 genes is a major mechanism, in response to ER stress, elevating plasma transaminases. Increases in plasma and tissue transaminases might represent a normal response to stress for survival. PMID:23532846

    The influence of Ukrain on the activity of aminotransferases (ALT and AST) and on the serum total protein content was estimated in mice and rats of both sexes receiving single or repeated doses of the drug. It was found that one hour after intraperitoneal (i.p.) administration of Ukrain no characteristic changes were recorded in the activity of the investigated enzymes, or in the serum protein content of animals of either sex. Similar effects were observed after three months treatment with Ukrain in rats of either sex. Only in mice receiving Ukrain for three months was a rise in ALT and AST activity found. No particular changes were observed in the total serum protein level, except for a small decreases in the sera of male mice.

    A novel agarolytic, Gram-stain negative, heterotrophic, facultatively anaerobic and pale-white pigmented bacterial strain, designated Q1(T), was isolated from the marine alga Porphyra yezoensis Ueda (AST58-103) collected from the coastal area of Weihai, China. The cells are motile by means of peritrichous flagella. The isolate requires NaCl for growth, while seawater is not necessary, and growth occurs optimally at about 30-33 °C, in 1-3 % (w/v) NaCl and at pH 7-7.5. Strain Q1(T) shows oxidase-positive and catalase-negative activities, and possesses the ability to hydrolyse starch and alginate, but not cellulose, gelatin, urea or Tween-80. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain Q1(T) is affiliated with the family Alteromonadaceae within the class Gammaproteobacteria. The isolate, strain Q1(T), is most closely related to Catenovulum agarivorans YM01(T) (94.85 %), with less than 91.2 % sequence similarity to other close relatives with validly published names. The draft genome sequence of strain Q1(T) consists of 62 contigs (>200 bp) of 4,548,270 bp. The genomes of Q1(T) and YM01(T) have an ANI value of 70.7 %, and the POCP value between the two genomes is 64.4 %. The genomic DNA G+C content of strain Q1(T) is 37.9 mol% as calculated from the draft genome sequence. The main isoprenoid quinone is ubiquinone-8. The predominant cellular fatty acids are summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH), C16:0 and C18:1 ω7c. The major polar lipids are phosphatidylethanolamine and phosphatidylglycerol. Based on data from a polyphasic chemotaxonomic, physiological and biochemical study, strain Q1(T) should be classified as a novel species of the genus Catenovulum, for which the name Catenovulum maritimus sp. nov. is proposed. The type strain is Q1(T) (=CICC 10836(T)=DSM 28813(T)).

    Worldwide, Egypt has a high prevalence of adult hepatitis C virus (HCV) infection. Serum alanine aminotransferase (ALT) activity is most commonly measured to assess hepatic disease. The revision of the definition of the normal limits for the ALT level is advisable. The aim of this work was to compare the histopathological changes in the liver tissue biopsies of HCV-infected patients, clinically presenting with ALT levels below normal, based on the conventional, previously used upper limit of normal (ULN) of ALT (40U/L for men and 30U/L for women) with the proposed new ULN (30U/L for men, and 19U/L for women). This is a retrospective cross-sectional study. A total of 668 cases of chronic hepatitis C genotype 4 were included. Patients were classified according to grades of histological activity and fibrosis stages (by the Metavir scoring system). They were also classified into normal and high groups according to the old and new cutoffs of both aspartate transaminase (AST) and ALT levels. The results of our study showed that the serum AST level in our study showed a better correlation with the histopathological changes in liver biopsy rather than ALT, especially when using the old cutoff of the ULN for AST. The serum ALT level in our study (both the old and the new cutoffs) did not show a significant correlation with the histopathological status in the liver biopsies of our patients. This study concluded that the old cutoff of the ULN AST is a better predictor of fibrosis. Copyright © 2015 Arab Journal of Gastroenterology. Published by Elsevier B.V. All rights reserved.

    To assess the relationship between De Ritis (aspartate aminotransaminase [AST]/Alanine aminotransaminase [ALT]) ratio and pathological variables and whether it is an independent prognostic factor. We analyzed 298 consecutive patients who underwent radical or partial nephrectomy for non-metastatic renal cell carcinoma (RCC) between 2006 and 2015. The association between De Ritis ratio and pathological variables including tumor size, presence of renal vein invasion, vena cava invasion, renal capsule infiltration, Gerota fascia invasion, renal sinus involvement, renal pelvic invasion, angiolymphatic invasion, adrenal gland involvement, lymph node involvement, tumor necrosis, and Fuhrman's grade was tested. Multivariable Cox analysis was performed to evaluate the impact of this ratio on overall survival and cancer-specific survival. An increased preoperative De Ritis ratio was significantly associated with renal vein invasion, renal capsule infiltration and renal pelvis involvement (p<0.05) in non-metastatic RCC. On multivariate analysis we found that tumor size, Fuhrman grade and lymph node involvement were independent prognostic factors for cancerspecific survival. AST/ALT ratio had no influence on the risk of overall and cancerspecific survival. An increased preoperative AST/ALT ratio had a significant association with renal vein invasion, renal capsule infiltration and renal pelvis involvement in patients with non-metastatic RCC. However, it does not appear to be an independent prognostic marker in non-metastatic RCC. Copyright® by the International Brazilian Journal of Urology.

    Biochemical tests such as aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are useful for diagnosing patients with liver disease. In this study, we tested the association between copy number variation and the hepatic biomarkers AST and ALT based on 8,842 samples from population-based cohorts in Korea. We used Affymetrix Genome-Wide Human 5.0 arrays and identified 10,534 CNVs using HelixTree software. Of the CNVs tested using univariate linear regression, 100 CNVs were significant for AST and 16 were significant for ALT (P < 0.05). We identified 39 genes located within the CNV regions. DKK1 and HS3ST3B1 were shown to play roles in heparan sulfate biosynthesis and the Wnt signaling pathway, respectively. NAF1 and NPY1R were associated with glycoprotein processes and neuropeptide Y receptor activity based on GO categories. PTER, SOX14 and TM7SF4 were expressed in liver. DPYS and CTSC were found to be associated with dihydropyrimidinuria and Papillon-Lefevre syndrome phenotypes using OMIM. NPY5R was found to be associated with dyslipidemia using the Genetic Association Database.

    Hepatic fibrosis is an important prognostic factor in chronic hepatitis B. Liver biopsy is a gold standard diagnostic tool but an invasive procedure, so it cannot be done on all patients. We evaluated the clinical efficacy of AST/ALT ratio and platelet counts as predictors of fibrosis in chronic hepatitis B. We reviewed retrospectively clinical records of 323 patients, who visited Kyungpook National University Hospital for chronic hepatitis B and underwent liver biopsy from September 1998 to May 2002. Correlation with laboratory parameters with hepatic fibrosis stage was identified. Of 323 patients, there were 278 male patients with mean age 27 (9~59). Platelet counts showed a significant correlation (r=-0.343, p=0.000), and AST/ALT ratio showed a weak but significant correlation (r=0.137, p=0.013) with fibrosis stage. Patients with severe fibrosis or cirrhosis (stage 3 and 4) can be identified to have AST/ALT ratio > 1 and platelet counts 1 in combination with platelet counts. However, its sensitivity is too low to replace liver biopsy.

    Under a contract with CH2M Hill Hanford Group, Inc., PNNL has performed a review of the NDE technology and methods for examination of the concrete dome structure of Hanford’s double-shell tanks. The objective was to provide a matrix of methodologies that could be evaluated based on applicability, ease of deployment, and results that could provide information that could be used in the ongoing structural analysis of the tank dome. PNNL performed a technology evaluation with the objective of providing a critical literature review for all applicable technologies based on constraints provided by CH2M HILL. These constraints were not mandatory, but were desired. These constraints included performing the evaluation without removing any soil from the top of the tank, or if necessary, requesting that the hole diameter needed to gain access to evaluate the top of the tank structure to be no greater than approximately 12-in. in diameter. PNNL did not address the details of statistical sampling requirements as they depend on an unspecified risk tolerance. PNNL considered these during the technology evaluation and have reported the results in the remainder of this document. Many of the basic approaches to concrete inspection that were reviewed in previous efforts are still in use. These include electromagnetic, acoustic, radiographic, etc. The primary improvements in these tools have focused on providing quantitative image reconstruction, thus providing inspectors and analysts with three-dimensional data sets that allow for operator visualization of relevant abnormalities and analytical integration into structural performance models. Available instruments, such as radar used for bridge deck inspections, rely on post-processing algorithms and do not provide real-time visualization. Commercially available equipment only provides qualitative indications of relative concrete damage. It cannot be used as direct input for structural analysis to assess fitness for use and if

    There are 760 feederpipes, which they are connected to inlet/outlet of the 380 pressure tube channels on the front of the calandria, in CANDU-type Reactor of Wolsung Nuclear Power Plant. As an ISI(In-Service Inspection) and PSI (Post-Service Inspection) requirements, maintenance activities of measuring the thickness of curvilinear part of feederpipe and inspecting the feederpipe support area within calandria are needed to ensure continued reliable operation of nuclear power plant. And ultrasonic probe is used to measure the thickness of curvilinear part of feederpipe, however workers are exposed to radioactivity irradiation during the measurement period. But, it is exposed to radioactivity irradiation during the measurement period. But, it is impossible to inspect feederpipe support area thoroughly because of narrow and confined accessibility, that is , an inspection space between the pressure tube channels is less than 100 mm and pipes in feederpipe support area are congested. And also, workers involved in inspecting feederpipe support area are under the jeopardy of high-level radiation exposure. Concerns about sliding home, which make the move of feederpipe connected to pressure tube channel smooth as pressure tube expands and contracts in its axial direction, stuck to feedeerpipe support and some of the structural components have made necessary the development of video inspection probe system with narrow and confined accessibility to observe and inspect feederpipe support area more close. Using video inspection probe system, it is possible to inspect and repair abnormality of feederpipe support connected to pressure tube channels of the calandria more accurate and quantative than naked eye. Therefore, that will do much for ensuring safety of CANDU-type nuclear power plant. 45 figs.,31 tabs. (Author)

    The AST/ALT ratio has shown good diagnostic accuracy in patients with chronic viral liver disease. However, its prognostic utility has never been tested. Recently, the Model for End-Stage Liver Disease (MELD) has been proposed as a simple and effective tool to predict survival in patients with liver cirrhosis. The aims of this study were to assess the 3-month and 1-yr prognostic ability of the AST/ALT ratio in a series of patients with virus-related liver cirrhosis, and to evaluate the relationship between the AST/ALT ratio and the MELD score and to compare their prognostic ability. The AST/ALT ratios and MELD scores of 99 patients with liver cirrhosis of viral etiology (73 patients with hepatitis C virus and 26 with hepatitis B virus) who had been followed-up for at least 1 yr were retrospectively calculated and correlated with the patients' 3-month and 1-yr prognosis. Receiver operating characteristic curves were used to determine the AST/ALT ratio and the MELD score cut-offs with the best sensitivity (SS) and specificity (SP) in discriminating between patients who survived and those who died. Univariate survival curves were estimated by the Kaplan-Meier method using the cut-offs identified by means of receiver operating characteristic curves. AST/ALT ratios and MELD scores showed a significant correlation (r(s) = 0.503, p = 0.0001). In all, 8% and 30% of the patients had died after 3 months and 1 yr of follow-up, respectively. AST/ALT ratios and MELD scores were significantly higher among the patients who died during both 3-month and 1-yr follow-up. An AST/ALT ratio cut-off of 1.17 had 87% SS and 52% SP, whereas a MELD cut-off of 9 had 57% SS and 74% SP in discriminating between patients who survived and those who died after I yr. The combined assessment of the AST/ALT ratio and/or MELD score had 90% SS and 78% SP. Survival curves of the patients showed that both parameters clearly discriminated between patients who survived and those who died in the short term

    The recent discoveries and excitement generated by space satellite experiment EGRET (presently operating on Compton Gamma Ray Observatory -- CGRO) have prompted an investigation into modern detector technologies for the next generation space based gamma ray telescopes. The GLAST proposal is based on silicon strip detectors as the open-quotes technology of choiceclose quotes for space application: no consumables, no gas volume, robust (versus fragile), long lived, and self triggerable. The GLAST detector basically has two components: a tracking module preceding a calorimeter. The tracking module has planes of crossed strip (x,y) 300 μm pitch silicon detectors coupled to a thin radiator to measure the coordinates of converted electron-positron pairs. The gap between the layers (∼5 cm) provides a lever arm for track fitting resulting in an angular resolution of <0.1 degree at high energy. The status of this R ampersand D effort is discussed including details on triggering the instrument, the organization of the detector electronics and readout, and work on computer simulations to model this instrument

    Full Text Available DaBeiNong (DBN Technology Group Co Ltd is a private enterprise, at the cutting edge of the agricultural high-tech industry in China. It has developed its innovative capabilities through Research and Development (R&D activities, skilled R&D personnel, new products, services, processes and markets. This study contributes to knowledge by identifying and constructing a model of the enterprise innovation capacity; the inputs and outputs of innovation in DBN and 9 other agricultural high-tech enterprises in China. We analyzed the enterprise technology innovation capacity and offered recommendations. Two sets of questionnaires were used; for the peasant farmers, and for the agricultural enterprises. We used the rank factors on an ordinal scale and simple percentages. We used econometric model to analyze seven factors of agricultural enterprise innovation capacity. The results show that R&D is strategic to Agricultural Enterprise Innovation Capacity (AETIC. However, the benefits to the peasant farmers need to be further intensified, and stepped up from its present average level. We found that enterprises with higher capital and larger sales have more R&D investment than those with smaller sales. Promoting agricultural research and rural development is crucial to pro-poor growth, given the potential for smallholder agriculture to rapidly absorb and adopt innovations.

    Nonalcoholic fatty liver disease (NAFLD) is being increasingly recognized as a cause of chronic liver disease. It has also been associated with devastating outcomes such as decompensated liver cirrhosis and hepatocellular carcinoma, as well as diabetes and metabolic syndrome. This study was conducted in order to assess liver fibrosis using Fibroscan, and to compare these results to the use of Fibrosis-4 (FIB-4) scores, AST platelet ratio index (APRI scores), and the AST/ALT ratios on NAFLD patients. A cross sectional study was conducted on NAFLD patients who underwent Fibroscan examinations between September 1, 2011 and June 30, 2014. Demographic data was collected, including sex, age, and nationality; serum alanine aminotransferase levels (ALT, 30 - 65 U/L), serum aspartate aminotransferase levels (AST, 15 - 37 U/L), and platelet counts (150 - 400 k/μL) were also determined. The stages of fibrosis (F0 1 - 6, F1 6.1 - 7, F2 7 - 9, F3 9.1 - 10.3, and F4 ≥ 10.4) were defined in kPa. For each patient, the AST/ALT ratio was also measured. The results of APRI and FIB-4 were compared with the Fibroscan fibrosis scores. The results of 122 patients were analyzed, including 65 (53.3%) males with a mean age of 50.2 years (SD: 13.7; range: 18 - 86). The males were significantly younger than the females (48.7 years (SD: 16.03) versus 51.8 years (SD: 10.3 P = 0.05), respectively). The mean stiffness score was 12.02 (SD: 12.7) kPa. Forty-four patients (36%) had advanced fibrosis. The mean platelet and serum ALT levels were normal. There was a significant positive correlation between the Fibroscan results and the AST/ALT ratios, the APRI scores, and the FIB-4 results. Similarly, there was a significant positive correlation between age and fibrosis score, and a significant negative correlation between platelet count and stiffness score. The data showed that more than one-third of the cohort exhibited advanced fibrosis, demonstrating the need for the early diagnosis and

    Full Text Available The AderDoutchiMaggia in Niger, as with other Sahelian zones, undergoes a process of climatic deterioration, which combines with the growing social and economic needs of the increasing population and causes a general economic crisis. Land degradation due to biophysical factors requires that priority action be given to land reclamation and soil conservation and to activities intended to increase agricultural production. This paper takes a look at socio-economic and established factors affecting the adoption of soil and water control technology (SWCT in Keita valley, a semi-arid area in the central of Niger. Well-designed questionnaire survey on key agents was used to gather the indispensable data from farm ménages. The binary dichotomous logistic regression model prognosticated six factors to be affecting the adoption of soil and water control technology in Keita. These variables cover the gender of the respondent, age of the household’s head, income evolution within the family, small craft referring to off farm income, training provide by local institutions, use of credit and, possession of full rights on land and its resources. The results revealed that diffusion of adoption from local organized community is a good alternative to increase the adoption of soil and water control technology in Keita valley agriculture system in Niger. Researchers and policy makers should conceive proper strategies and agenda reflecting the farmers’ interest, position and restriction in advocating new technologies for greater assumption and adoption by the farmers.

    The IAEA General Conference in 2000 has invited ''all interested Member States to combine their efforts under the aegis of the Agency in considering the issues of the nuclear fuel cycle, in particular by examining innovative and proliferation-resistant nuclear technology''. In response to this invitation, the IAEA initiated an ''International Project on Innovative Nuclear Reactors and Fuel Cycles'', INPRO. The overall objectives of INPRO is to help to ensure that nuclear energy is available to contribute in fulfilling in a sustainable manner energy needs in the 21st century, and to bring together all interested Member States, both technology holders and technology users, to consider jointly the international and national actions required to achieve desired innovations in nuclear reactors and fuel cycles that use sound and economically competitive technology. Phase-I of INPRO was initiated in May 2001. During Phase-I, work was subdivided in two sub phase: Phase 1A (finished in June 2003) and Phase 1B (started in June 2003). Phase 1A dealt with the definition of Basic Principles, User Requirements and Criteria, and the development of a methodology for the evaluation of innovative nuclear technologies. In Phase 1A, task groups for several areas were established: (a) Prospects and Potentials of Nuclear Power, (b) Economics; (c) Sustainability and Environment, (d) Safety of Nuclear Installations, (e) Waste Management, (f) Proliferation Resistance, (g) Crosscutting issues and (h) for the Methodology for Assessment. In Phase-IB evaluations of innovative nuclear energy technologies will be performed by Member States against the INPRO Basic Principles, User Requirements and Criteria. This paper summarizes the results achieved in the Phase 1A of INPRO and is a cooperative effort of the INPRO team, consisting of all INPRO cost free experts and task managers. (author)

    The nuclear community is currently at a stage where existing reactor control stations are undergoing various forms of modernization, new reactors are being built in many countries with computer-based control rooms, and advanced reactors are being designed through international cooperation to support power generation for decades to come. With the introduction of advanced plants, we will see new reactor and system designs, new tools to support plant personnel, and changes to nuclear power plant (NPP) staffing configurations. The concepts of operation and maintenance for this new generation of plants are likely to be quite different from those employed in today's plants. It is important that the potential impact of these developments is evaluated and understood by prospective operators and regulators responsible for determining the acceptability of new designs to support human performance in maintaining plant safety. The introduction of new technology is viewed as having promise for improving the safe and efficient operation of NPPs. To ensure the appropriate application of technology to support human performance and plant safety, it is important to evaluate the technological advances in terms of both potential negative and positive effects. Research described in this paper can provide the technical basis to help ensure that the benefits of new technology are realized and that the potential negative effects are minimized. The impetus for the current effort grew out of a Nuclear Energy Agency, Committee on the Safety of Nuclear Installations, Working Group on Human and Organizational Factors, Technical Opinion Paper (TOP) titled, 'Research on Human Factors in New Nuclear Plant Technology' [NEA/CSNI/R(2009)7], which identified eight broad topic areas that warrant further research: 1. Operating Experience (OpEx) from New and Modernized Plants. 2. Evolving Concepts for the Operation of Nuclear Power Plants. 3. The Role of Automation and Personnel: New Concepts of Teamwork

    In the context of the overall programme of the West German Ministry of Research and Technology on the technical use of solar energy, a manufacturing process for thin film solar cells based on the hetero-transition Cu/sub 2/S/CdS on the laboratory scale was developed at the University of Stuttgart. Efficiencies of up to 8% were achieved for individual cells with dimensions 7 x 7 cm/sup 2/. The stability of the system was proved out of doors and in accelerated tests by thermal cycling for individual cells. The aim of the present FvE project at NUKEM is the transfer of the manufacturing process developed on the laboratory scale to an industrial production process. A pilot plant with all the necessary components should be built on the Technical College scale, so that by evaluating the results obtained from this plant, a demonstration plant with a production capacity of 500 KWp/annum can be designed.

    Full Text Available Abstract Background With the increase in use of point-of-care diagnostic tests for malaria and other diseases comes the necessity of storing the diagnostic kits and the drugs required for subsequent management, in remote areas, where temperatures are high and electricity supply is unreliable or unavailable. Methods To address the lack of temperature-controlled storage during the introduction of community-based malaria management in Cambodia, the Cambodian National Centre for Parasitology, Entomology and Malaria Control (CNM developed prototype evaporative cooling boxes (Cambodian Cooler Boxes - CCBs for storage of perishable medical commodities in remote clinics. The performance of these CCBs for maintaining suitable storage temperatures was evaluated over two phases in 2005 and 2006-7, comparing conditions in CCBs using water as designed, CCBs with no water for evaporation, and ambient storage room temperatures. Temperature and humidity was monitored, together with the capacity of the RDTs recommended for storage between 2 to 30 degree Celsius to detect low-density malaria parasite samples after storage under these conditions. Results Significant differences were recorded between the proportion of temperatures within the recommended RDT storage conditions in the CCBs with water and the temperatures in the storage room (p Discussion and Conclusions The CCB was an effective tool for storage of RDTs at optimal conditions, and extended the effective life-span of the tests. The concept of evaporative cooling has potential to greatly enhance access to perishable diagnostics and medicines in remote communities, as it allows prolonged storage at low cost using locally-available materials, in the absence of electricity.

    Because of an insufficient number of human organs for transplantation, xenotransplantation may become an effective alternative. We aimed to analyze if the type of transgenesis has an influence on the hepatic caspase-3 expression, the enzyme that executes apoptosis as well as ALT, AST, and GGT activity after 24 hours of cold storage. The experiment was carried out on the 24 livers of Polish White Landrace pigs carrying human α1,2-fucosyltransferase and/or α-galactosidase (GAL) genes and livers without this genetic modification (control). Livers were perfused, stored for 24 hours in solution, and subsequently re-flushed. Hepatic concentration of the caspase-3 protein and its mRNA expression were measured just after the animal was killed as well as after 30 minutes of perfusion and after 24 hours of cold storage followed by 30 minutes of reperfusion. Caspase-3 mRNA level was detected with the RT-PCR method. Protein concentration (capsase-3 active and inactive) was assessed with the Western blotting technique. Kinetic methods were applied for the analysis of the ALT, AST, and GGT activity. The highest increase of the ALT activity after cold storage was observed in the group with GAL transgenesis, whereas the GGT activity was highest in the unmodified livers. There was no difference in the caspase-3 expression and AST activity after cold storage as compared with the respective initial results (P = .57 and P = .97, respectively). It appears that transgenesis does not aggravate ischemic injury of the liver. Copyright © 2016 Elsevier Inc. All rights reserved.

    AST-120 is used to decrease the abundance of serum uremic toxins in treatment of chronic kidney disease; however, it could also adsorb concomitantly administered drugs. This study aimed to develop a prediction method for drug interaction between AST-120 and concomitantly administered drugs based on in vitro dissolution and in vivo absorption behavior. Sixty-eight drugs were selected for the analysis. For each drug, theoretical dissolution (R d ) and absorption (R a ) rates at estimated dosing intervals (1, 30, 60, 90, 120, and 240 min) were calculated using the Noyes-Whitney formula and compartment analysis, respectively. The optimal thresholds for R d and R a (R dth and R ath ) were estimated by comparing the results with those of previous drug interaction studies for six drugs. Four drug interaction risk categories for 68 drugs at each dose interval were defined according to the indices of dissolution and absorption against their thresholds. The in vitro dissolution and in vivo absorption behavior of the selected drugs were well fitted to the Noyes-Whitney formula and one- or two-compartment models. The optimal R dth and R ath that gave the highest value of consistency with the equivalence of drug interaction studies were 90 and 30 %, respectively. As the dosing intervals were lengthened, the number of drugs classified into the low-risk categories increased. A new drug interaction prediction method based on the pharmacokinetic parameters of drugs was developed. The new model is useful for estimating the risk of drug interaction in clinical practice when AST-120 is used in combination with other drugs.

    A value of > or = 1 for the ratio of aspartate amino-transferase to alanine aminotransferase (the AST/ALT ratio or AAR) has been shown to have a positive predictive value of 100% for the diagnosis of cirrhosis in patients with chronic hepatitis C. If validated on separate cohorts, an AAR > or = 1 might obviate the need for liver biopsy in some patients with hepatitis C. We attempted to validate the AAR by abstracting demographic and clinical data from a database of consecutive patients with hepatitis C who had a liver biopsy between 1993 and 1998. We used definitions, methods of data collection, and analyses comparable to those of the published study. A hepatopathologist blindly reviewed 49 liver biopsies for histological grade and stage. The current cohort of 177 patients and the previous cohort of 139 patients were comparable in mean age (42.3 vs 43.8 yr), percentage of men (63 vs 67), percentage with an AAR > or =1 (20 vs 17), and Child-Pugh distribution, but differed in substantial use of ethanol (11% vs 3.6%; p = 0.01) and in the prevalence of cirrhosis (23% vs 34%, p = 0.06). Respective sensitivities of the AAR were 56% and 53%. An AAR > or =1 had a positive predictive value of 64% (95% confidence interval 48-78%) for the current cohort. Thirteen of 36 patients (36%) with an AAR > or =1 were incorrectly identified as having cirrhosis. Of these 13 patients, 6 had a normal AST and ALT, 5 had a minimally elevated AST or ALT, and 1 had advanced fibrosis without cirrhosis. These results suggest that an AAR > or =1 may not be as useful for predicting cirrhosis in chronic hepatitis C as previously thought, and emphasizes the need for validation of clinical decision aids on independent patient cohorts.

    Hepatitis B virus (HBV) and hepatitis C virus (HCV) are the two major causes of chronic liver inflammation, fibrosis and cirrhosis. They have the ability to cause persistent infection in susceptible hosts and severely damage liver function. Matrix metalloproteinase-9 (MMP-9) is one of the gelatinases that may be important in liver fibrosis. This study aims to evaluate whether or not MMP-9 in relation to viral load is involved in the development of liver dysfunction in HBV and HCV Blood samples from 20 patients chronically infected with HBV and 30 with HCV, along with 15 healthy individuals as controls, were investigated. Viral load was assessed by real-time polymerase chain reaction (PCR). Serum MMP-9 levels were evaluated by enzyme-linked immunosorbent assay (ELISA). Alanine transaminase and aspartate aminotransferase (ALT and AST) activities were measured spectrophotometrically. Levels of MMP-9 were significantly higher in HCV than in HBV patients (P < 0.01), and positively correlated with HBV viral load (r = 0.842, P < 0.01) and AST:ALT ratio (r = 0.614, P < 0.05). Conversely, MMP-9 levels did not correlate with HCV viral load but did correlate with AST:ALT ratio (r = 0.652, P < 0.01). Therefore, MMP-9 levels could reflect progressive liver damage in HBV and HCV infection. However, a distinction between the pathological mechanism of HCV and HBV is suggested, as HCV probably promotes hepatocyte damage and fibrosis through mechanisms other than replication. Continuous expression of the HBV genome through replication and secretion of viral antigens may contribute to the transcriptional regulation of MMP-9, thus promoting liver damage and fibrosis.

    Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT) measurements are important for the assessment of liver damage. The aim of this study was to define the reference intervals (RIs) for these enzymes in adults, paying attention to standardization of the methods used and careful selection of the reference population. AST, ALT and GGT were measured with commercial analytical systems standardized to the IFCC-recommended reference measurement systems. Three centers (two in Italy and one in China) measured their own freshly collected samples; one of these centers also measured frozen samples from the Nordic Countries RI Project and from a Turkish center. RIs were generated using non-parametric techniques from the results of 765 individuals (411 females and 354 males, 18-85 years old) selected on the basis of the results of other laboratory tests and a specific questionnaire. AST results from the four regions (Milan, Beijing, Bursa and Nordic Countries) were statistically different, but these differences were too small to be clinically relevant. Likewise, differences between the upper reference limits for genders was only 1.7 U/L (0.03 μkat/L), allowing a single RI of 11-34 U/L (0.18-0.57 μkat/L) to be defined. Interregional differences were not statistically significant for ALT, but partitioning was required due to significant gender differences. RIs for ALT were 8-41 U/L (0.13-0.68 μkat/L) for females and 9-59 U/L (0.15-0.99 μkat/L) for males, respectively. The upper reference limits for GGT from the Nordic Country population were higher than those from the other three regions and results from this group were excluded from final calculations. The GGT RIs were 6-40 U/L (0.11-0.66 μkat/L) for females and 12-68 U/L (0.20- 1.13 μkat/L) for males, respectively. For AST and ALT, the implementation of common RIs appears to be possible, because no differences between regions were observed. However, a common RI for GGT that is

    Chromosomal inversion polymorphism affects nucleotide variation at loci associated with inversions. In Drosophila subobscura, a species with a rich chromosomal inversion polymorphism and the largest recombinational map so far reported in the Drosophila genus, extensive genetic structure of nucleotide variation was detected in the segment affected by the O(3) inversion, a moderately sized inversion at Muller's element E. Indeed, a strong genetic differentiation all over O(3) and no evidence of a higher genetic exchange in the center of the inversion than at breakpoints were detected. In order to ascertain, whether other polymorphic and differently sized inversions of D. subobscura also exhibited a strong genetic structure, nucleotide variation in 5 gene regions (P236, P275, P150, Sxl, and P125) located along the A(2) inversion was analyzed in A(st) and A(2) chromosomes of D. subobscura. A(2) is a medium-sized inversion at Muller's element A and forms a single inversion loop in heterokaryotypes. The lower level of variation in A(2) relative to A(st) and the significant excess of low-frequency variants at polymorphic sites indicate that nucleotide variation at A(2) is not at mutation-drift equilibrium. The closest region to an inversion breakpoint, P236, exhibits the highest level of genetic differentiation (F(ST)) and of linkage disequilibrium (LD) between arrangements and variants at nucleotide polymorphic sites. The remaining 4 regions show a higher level of genetic exchange between A(2) and A(st) chromosomes than P236, as revealed by F(ST) and LD estimates. However, significant genetic differentiation between the A(st) and A(2) arrangements was detected not only at P236 but also in the other 4 regions separated from the nearest breakpoint by 1.2-2.9 Mb. Therefore, the extent of genetic exchange between arrangements has not been high enough to homogenize nucleotide variation in the center of the A(2) inversion. A(2) can be considered a typical successful inversion

    The project was initiated to assist the State of Montana to develop a methodology to ameliorate acid mine drainage problems associated with the abandoned mines located in the Stockett/Sand Coulee area near Great Falls, Montana. Extremely acidic water is continuously discharging from abandoned coal mines in the Stockett/Sand Coulee area at an estimated rate of greater than 600 acre-feet per year (about 350 to 400 gallons per minute). Due to its extreme acidity, the water is unusable and is contaminating other water supplies. Most of the local alluvial aquifers have been contaminated, and nearly 5% of the private wells that were tested in the area during the mid-1980's showed some degree of contamination. Significant government money has been spent replacing water supplies due to the magnitude of this problem. In addition, millions of dollars have been spent trying to remediate acid mine drainage occurring in this coal field. To date, the techniques used have focused on the management and containment of mine waters, rather than designing technologies that would prevent the formation of acid mine drainage

    Full Text Available The care and protection of the mountain areas and their traditional crops were some of the reasons that led regional governments of Liguria and Tuscany to participate in the strategic project “Sea, Countryside and Land: potentiate the strategic unitarily” (MARS +. This project has also involved the participation of the four cross-border regions: Tuscany (leader, Sardinia, Liguria and Corsica. The aim was to promote the development of the innovations and entrepreneurship in the rural areas in order to increase competitiveness. In particular, the subproject SC has provided the transfer of innovations to facilitate the processes of mechanization in vineyards and olive orchards in contexts defined as “heroic”, areas of high landscape and environmental value in which the typical cultures has been always carried out, generally, on terraces or slopes. These conditions require a great effort by the farmers and result in high production costs. The transfer of the innovations has provided the organization of demonstration days in which the technological solutions for the management of the farming operations in vineyards and olive orchards were proposed and tested. During these events, the participative process was fundamentally reconfirmed, not only as a means to expand the knowledge of innovative products, but also as an opportunity for farmers, retailers, manufacturers, researchers, and local administrators to interact and facilitate the development of other technologies. The parameters that led to the innovative solutions included: the small size, user-friendliness, agility, and the ability of operating on systems not easily accessible. These products must also ensure the ergonomics and safety of workers performing all the growing operations. A thorough research of the available technologies and prototypes, still under development, affirms the presence of many innovations. These innovations not only allow the execution of all the field

    Full Text Available Dupuytren’s disease (palmar fibromatosis involves nodules in fascia of the hand that leads to flexion contractures. Ledderhose disease (plantar fibromatosis is similar with nodules of the foot. While clinical aspects are well-described, genetic mechanisms are unknown. We report a family with cardiac disease due to a heterozygous LMNA mutation (c.736C>T, p.Gln246Stop with palmar/plantar fibromatosis and investigate the hypothesis that a second rare DNA variant increases the risk for fibrotic disease in LMNA mutation carriers. The proband and six family members were evaluated for the cardiac and hand/feet phenotypes and tested for the LMNA mutation. Fibroblast RNA studies revealed monoallelic expression of the normal LMNA allele and reduced lamin A/C mRNAs consistent with LMNA haploinsufficiency. A novel, heterozygous missense variant (c.230T>C, p.Val77Ala in the Asteroid Homolog 1 (ASTE1 gene was identified as a potential risk factor in fibrotic disease using exome sequencing and family studies of five family members: four LMNA mutation carriers with fibromatosis and one individual without the LMNA mutation and no fibromatosis. With a possible role in epidermal growth factor receptor signaling, ASTE1 may contribute to the increased risk for palmar/plantar fibromatosis in patients with Lamin A/C haploinsufficiency.

    The level of anine aminotransferase/aspartate aminotransferase (ALT/AST) ratio in the serum was often used to assess liver injury. Whether the ALT/AST ratio (LSR) was associated with prognosis for gastric adenocarcinoma (GA) has not been reported in the literature. Our aim was to investigate the prognostic value of the preoperative LSR in patients with GA. A retrospective study was performed in 231 patients with GA undergoing curative resection. The medical records collected include clinical information and laboratory results. We investigated the correlations between the preoperative LSR and overall survival (OS). Survival analysis was conducted with the Kaplan-Meier method, and Cox regression analysis was used to determine significant independent prognostic factors for predicting survival. A p value of 0.80. The LSR was independently associated with OS in patients with GA (hazard ratio: 0.610; 95% confidence interval: 0.388-0.958; p = 0.032), along with tumor stages (hazard ratio: 3.118; 95% confidence interval: 2.044-4.756; p < 0.001) and distant metastases (hazard ratio: 1.957; 95% confidence interval: 1.119-3.422; p = 0.019). Our study first established a connection between the preoperative LSR and patients undergoing curative resection for GA, suggesting that LSR was a simple, inexpensive, and easily measurable marker as a prognostic factor, and may help to identify high-risk patients for treatment decisions.

    To observe therapeutic effect of acupoint-injection of Kaixilai on non-alcoholic fatty liver. One hundred cases of non-alcoholic fatty liver were randomly divided into a test group and a control group, 50 cases in each group. The test group were treated with injection of 2 mL Kaixilai injection into Zusanli (ST 36), thrice each week, for 3 months; and the control group were treated with intravenous drip of 200 mL Kaixilai injection, once each day, for 3 months. Changes of triglyceride (TG), total cholesterol (TC), malondialhyde (MDA), superoxide dismutase (SOD), glutamic-oxaloacetic transaminase (AST), glutamic-pyruvic transaminase (ALT), and clinical symptoms were observed in the two groups. There were significant differences before and after treatment in the symptoms, TG, TC, MDA, SOD, AST and ALT in the two groups (P0.05). Acupoint-injection of Kaixilai is an effective therapy for non-alcoholic fatty liver, with convenience, economic and no adverse effect.

    The development of esophageal varices depends on the progression of liver fibrosis. However, it has not yet been sufficiently clarified whether biomarkers of liver fibrosis can be used to predict the incidence of varices in cirrhotic patients with a well-maintained liver function (Child-Pugh class A). Three established markers of liver fibrosis, including AST-to-ALT ratios (AAR), FIB-4 and AST-to-platelet ratio indices (APRI), were analyzed in HCV-positive cirrhotic patients with Child-Pugh class A status, and the relationships between these markers and the risk of variceal bleeding were investigated. The values of AAR and FIB-4 in the patient with varices with a high risk of hemorrhage were significantly higher than those in the patients without high-risk varices, whereas the value of APRI was not found to be related to the risk of variceal bleeding. Of all the parameters examined, the values of AAR were the most significantly different between the two (with or without high-risk varices) groups. In addition, the values of AAR increased in line with variceal severity. The value of AAR is related to the severity and risk of variceal bleeding in patients with HCV-related compensated cirrhosis.

    2015-11-20

    The $H \\rightarrow WW^{\\ast}$ channel was one of the three search channels contributing in the observation of the Higgs boson at the ATLAS experiment in July 2012. Nowadays, this channel represents an important ingredient in the determination of the couplings and properties of the newly discovered particle. This thesis reports the search for and observation of the Higgs boson in the $H \\rightarrow WW^{\\ast}$ decay mode using the ATLAS detector at the CERN Large Hadron Collider. The analysis of events in which the Higgs boson is produced in the gluon-gluon fusion process and is associated with no more than one jet, is outlined in detail. The datasets used are the proton-proton collisions collected with the ATLAS detector at a centre of mass energy of 8 TeV during 2012 and 7 TeV during 2011, corresponding to a total integrated luminosity of 25 fb$^{-1}$. An excess over the predicted number of background events is observed in the data. The significance of the excess is estimated to be 6.1 standard deviations, ...

    The charter goal of the Agile Machining and Inspection Thrust Area Team is to identify technical requirements, within the nuclear weapons complex (NWC), for Agile Machining and Inspection capabilities. During FY 2008, the team identified Parametric Technology Corporation (PTC) Pro/CMM as a software tool for use in off-line programming of probing routines--used for measurement--for machining and turning centers. The probing routine would be used for in-process verification of part geometry. The same Pro/CMM program used on the machine tool could also be employed for program validation / part verification using a coordinate measuring machine (CMM). Funding was provided to determine the compatibility of the Pro/CMM probing program with CMM software (Zeiss DMISEngine).

    This report presents results from bench-scale treatability studies conducted under site-specific conditions to optimize the polyphosphate amendment for implementation of a field-scale technology demonstration to stabilize uranium within the 300 Area vadose and smear zones of the Hanford Site. The general treatability testing approach consisted of conducting studies with site sediment and under site conditions, to develop an effective chemical formulation and infiltration approach for the polyphosphate amendment under site conditions. Laboratory-scale dynamic column tests were used to (1) quantify the retardation of polyphosphate and its degradation products as a function of water content, (2) determine the rate of polyphosphate degradation under unsaturated conditions, (3) develop an understanding of the mechanism of autunite formation via the reaction of solid phase calcite-bound uranium and aqueous polyphosphate remediation technology, (4) develop an understanding of the transformation mechanism, the identity of secondary phases, and the kinetics of the reaction between uranyl-carbonate and -silicate minerals with the polyphosphate remedy under solubility-limiting conditions, and (5) quantify the extent and rate of uranium released and immobilized based on the infiltration rate of the polyphosphate remedy and the effect of and periodic wet-dry cycling on the efficacy of polyphosphate remediation for uranium in the vadose zone and smear zone

    1994-02-01

    We estimated clinical criteria of aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio that is measured by the consensus method of JSCC (Japan Society of Clinical Chemistry) for serum AST and ALT. The JSCC consensus method is closely correlated with both IFCC (International Federation of Clinical Chemistry) recommended method without pyridoxal phosphate and Karmen method recommended by the expert panel of liver function tests in Japanese Society of Gastroenterology. The slopes of the regression line is estimated to be 1.00 and 0.87 respectively. We propose that the decision making value of AST/ALT ratio to differentiate several types of liver diseases should be set to 0.87 measured by JSCC consensus method, instead of 1.0 measured by Karmen method.

    331 dogs, suffering from different intestinal diseases with diarrhea, were classified into the groups of "acute noninfectious", "infectious", "chronic" and "secondary enteropathies". The serum enzymes ALT, AST, GLDH, AP and GGT were determined. In all groups increases of enzyme activities were to be found. The highest and most frequent increases have been observed in acute noninfectious and in secondary enteropathies. The enzyme pattern in acute noninfectious enteropathies indicate a secondary liver disturbance in consequence of the intestinal disease, whereas the liver participation in secondary enteropathies is the effect of the primary disease other than intestinal disturbances. In comparison to this the height and number of increases of liver enzyme activities were low in acute infectious and in chronic enteropathies.

    Full Text Available Background: Diabetes is associated with many pathological changes and one of the most important consequences of the diabetes is hepatic injury. The present study was performed to investigate the effect of eight weeks endurance training with consumption of cinnamon supplementation on plasma concentrations of liver enzymes, alanine aminotransferase (ALT and aspartate aminotransferase (AST in women with type II diabetes. Methods: In this quasi-experimental study, 36 female volunteers with type II diabetes (age 52.72±2.64 years and body mass index 29.28±2.94 Kg/m2 were participated. The subjects were homogenized regarding their body mass index and then were divided randomly into four groups (each group=9 patients: Training, training-cinnamon, cinnamon, and Control. Endurance training was performed for eight weeks (three sessions per week at the intensity of 60-75% of maximum heart rate for 40-60 minutes. The consumption of cinnamon supplementation was 1.5 gr per day. Plasma concentrations of ALT and AST were measured following 12 hours fasting, 48 hours before and after performing the experiment, by the enzymatic method. Data were analyzed by paired t-test and factorial ANOVA, using SPSS version 21 (Chicago, IL, USA and at the significant level of P0.05. There was no significant difference between groups in pre and posttests. Conclusion: The results confirm that cinnamon supplementation may be effective in improving the plasma levels of ALT but the intensity and duration of an effective exercise training especially with consumption of cinnamon supplementation simultaneously need more study in diabetic patients.

Multivariate analysis indicated that preoperative LSR was an independent prognostic factor in GA. Patients with LSR ≤ 0.80 had a greater risk of death than those with LSR > 0.80. The LSR was independently associated with OS in patients with GA (hazard ratio: 0.610; 95% confidence interval: 0.388–0.958; p = 0.032, along with tumor stages (hazard ratio: 3.118; 95% confidence interval: 2.044–4.756; p < 0.001 and distant metastases (hazard ratio: 1.957; 95% confidence interval: 1.119–3.422; p = 0.019. Our study first established a connection between the preoperative LSR and patients undergoing curative resection for GA, suggesting that LSR was a simple, inexpensive, and easily measurable marker as a prognostic factor, and may help to identify high-risk patients for treatment decisions.

    Full Text Available Objective. To assess the association between plasma ceramides and hepatic steatosis (HS in adolescents, independently of obesity. Materials and Methods. Ninety-four adolescents from two previous studies conducted and published by our crew were included. Study subjects were stratified in three groups: normal weight (n=18, obesity (n=34, and obesity + HS (n=42. The presence of HS was defined when ALT/AST ratio was <1. Ceramides subspecies (C14:0, C16:0, C18:0, C24:0, and C24:1 were determined by LC/MS. Results. All ceramides correlated directly with ALT levels and inversely with ALT/AST ratio; the strongest correlation was observed among C14:0 ceramide (r=0.41 and r=-0.54, resp.; P<0.001. Furthermore, significant correlations were observed between cholesterol and all ceramides except for C24:1 ceramide. Interestingly ceramides C14:0, C18:0, and C24:1 correlated directly with both fasting insulin and HOMA-IR index. For assessing HS, a cut-off point of 10.3 nmol/L for C14:0 ceramide reported a sensitivity of 92.7% and a specificity of 73.5% when normal weight and obesity groups (n=52 were compared against obesity + HS group (n=42. Positive and negative predictive values were 77.5% and 90.2%, respectively. Conclusions. Plasma ceramides are closely associated with hepatic steatosis in adolescents. C14:0 ceramide could be a novel biomarker of HS independently of obesity.

    The levels of liver function tests (LFTs) are often used to assess liver injury and non-liver disease-related mortality. In our study, the relationship between pretreatment serum LFTs and overall survival (OS) was evaluated in esophageal squamous cell carcinoma (ESCC) patients. Our purpose was to investigate the prognostic value of the preoperative alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio and gamma glutamyltransferase (GGT) in ESCC patients. A retrospective study was performed in 447 patients with ESCC, and follow-up period was at least 60 months until death. The prognostic significance of serum LFTs were determined by univariate and multivariate Cox hazard models. LFTs including ALT, AST, LSR, GGT, TBA and LDH were analyzed. Serum LSR (HR: 0.592, 95% CI = 0.457-0.768, p < 0.001 and GGT (HR: 1.507, 95% CI = 1.163-1.953, p = 0.002) levels were indicated as significant predictors of OS. The 5-year OS among patients with higher LSR levels was longer compared with those patients with decreased LSR levels, not only in the whole cohort but also in the subgroups stratified by pathological stage (T1-T2 subgroup, T3-T4 subgroup, N0 subgroup and M0 subgroup). We also found that patients with a higher GGT might predict worse OS than patients with a normal GGT, not only in the whole cohort but also in the subgroups stratified by pathological stage (T3-T4 subgroup and N1-N2 subgroup). Both increased levels of LSR and decreased levels of GGT might predict shorter overall survival in ESCC patients. Our findings suggest that serum LSR and GGT levels could be used as a key predictor of survival in patients with ESCC.

    We report on the selective area growth of InAs nanowires on patterned SiO2/Si (1 1 1) nano-holes, prepared by focused helium ion beam technology. We used a single spot mode, in which the focused helium ion beam was fixed on a single point with a He+-ion dosage, ranging from 1.5 pC to 8 pC, to drill the nano-holes. The smallest hole diameter achieved is ∼8 nm. We found that low He+-ion dosage is able to facilitate the nucleation of (1 1 1)B InAs on the highly mismatched Si, leading to the vertical growth of InAs nanowires (NWs). High He-ion dosage, on the contrary, severely damaged Si surface, resulting in tilted and stripe-like NWs. In addition to titled NW grown from (1 1 1)A InAs domain, a new titled growth direction due to defect induced twinning was observed. Cross-sectional TEM images of vertical NWs show mixed wurtizite (WZ) and zincblende (ZB) phases, while WZ phase dominants. The stacking faults resulting from the phase change is proportional to NW diameter, suggesting that the critical diameter of phase turning is larger than 110 nm, the maximum diameter of our NWs. Period of misfit dislocation at the InAs/Si interface of vertical NW is also found larger than the theoretical value when the diameter of heterointerface is smaller than 50 nm, indicating that the small contact area is able to accommodate the large lattice and thermal mismatch between InAs and Si.

    The assessment of population structure and abundance of fish assemblages associated with artificial reefs (ARs) is an important aspect of AR management. In the present study, we used a Dive-Operated Stereo Video (stereo-DOV) technique to assess the population structure and abundance of Sebastes schlegeli associated with two metallic, and three wooden, vessel reefs in Haizhou Bay during 2012 and 2013. The study used video systems to obtain length measurements and estimates of abundance. The size composition of S. schlegeli differed among reefs and individuals around vessel reefs were all adults, with total lengths (TL) of >20 cm. Juvenile fish were encountered by divers in a rocky area near the island away from the vessel reefs. The largest individual S. schlegeli (with the highest TL) among five reefs were found around a metallic vessel reef in both 2012 and 2013. TL of S. s chlegeli from all reefs increased by an average of 3.2 cm ( P<0.05) from 2012 to 2013, with an estimated mean weight increase of 250.4 g ( P<0.05). The video survey also indicated a decrease in the biomass of schools near two metallic vessels between the years. Stereo-video technology was found to be suitable for rockfish surveys around the reefs.

    Half the global population lives within 60 km of the ocean, profoundly influencing environmental quality and services to local communities. Adoption of marine science curricula creates opportunities for educators and scientists to engage and entrain K-12 students as ocean stewards. In particular, boat-based science activities facilitate hands-on inquiry. These activities reinforce key science concepts while creating a tangible connection to our shared coastal "backyard." A collaboration between Zephyr Education Foundation, the New England Aquarium, the University of Massachusetts Boston and Woods Hole Oceanographic Institution has taken >500 Boston, MA area students from 26 public schools on boat-based education trips in Boston Harbor. Marine science and technology professionals and educators facilitate participatory activities using modern marine technology aboard a research vessel. Trips are funded at no cost to participants by a grant from the Richard Lounsbery Foundation; cost-free outings are essential for participation from underserved public school districts. Participants perceived three important outcomes of their outings: the trips 1) enhanced in-class curricular learning and improved marine science literacy 2) increased personal connections to local marine environments, and 3) increased interest in careers in marine science, including engineering and technical positions. Despite living in close proximity to water, this was the first boat outing for many students; boat-based education trips enhanced student awareness of local environments in a way that curricular study had not. Boston trip results are being evaluated, but 3000 evaluations from similar trips in Woods Hole, MA indicate that 98% of participants gained a better understanding and appreciation of the work conducted by marine scientists, engineers, and other professionals, and 82% said their experience made them more interested in becoming involved in science at school and/or as a job.

    A groundwater plume containing uranium, originating from a combination of purposeful discharges of wastewater to cribs, trenches and ponds, along with some accidental leaks and spills during nuclear fuel fabrication activities, has persisted beneath the Hanford Site 300 Area for many years. Despite the cessation of uranium releases and the removal of shallow vadose zone source materials, the goal of less than 30 (micro)g/L has not been achieved within the anticipated 10-year time period. Polyphosphate technology has been demonstrated to delay the precipitation of phosphate phases for controlled in situ precipitation of stable phosphate phases to control the long-term fate of uranium. Precipitation occurs when polyphosphate compounds hydrolyze to yield the orthophosphate molecule. Based on the hydrolysis kinetics of the polyphosphate polymer, the amendment can be tailored to act as a time-released source of phosphate for lateral plume treatment, immediate and sustained remediation of dissolved uranium, and to preclude rapid precipitation which could result in a drastic change in hydraulic conductivity of the target aquifer. Critical to successful implementation of polyphosphate remediation technology is a site specific evaluation and optimization of multi-length polyphosphate amendment formulations. A multi-faceted approach has been taken to provide key fundamental science knowledge regarding optimization of the polyphosphate remedy through: (1) phosphorus-31 nuclear magnetic resonance to quantify the effects of Hanford groundwater and sediment on the degradation of inorganic phosphates, (2) static tests to quantify the kinetics, loading, and stability of apatite as a long-term sorbent for uranium, and (3) single-pass flow through testing to quantify the stability of autunite and apatite under relevant site conditions. Dynamic column tests were utilized to (1) optimize the composition of the polyphosphate formulation for the formation and emplacement of apatite and

    Full Text Available BackgroundContinuous glucose monitoring (CGM is reported to be a useful technique, but difficult or inconvenient for some patients and institutions. We are developing a glucose area under the curve (AUC monitoring system without blood sampling using a minimally invasive interstitial fluid extraction technology (MIET. Here we evaluated the accuracy of interstitial fluid glucose (IG AUC measured by MIET in patients with diabetes for an extended time interval and the potency of detecting hyperglycemia using CGM data as a reference.MethodsThirty-eight inpatients with diabetes undergoing CGM were enrolled. MIET comprised a pretreatment step using a plastic microneedle array and glucose accumulation step with a hydrogel patch, which was placed on two sites from 9:00 AM to 5:00 PM or from 10:00 PM to 6:00 AM. IG AUC was calculated by accumulated glucose extracted by hydrogel patches using sodium ion as standard. ResultsA significant correlation was observed between the predicted AUC by MIET and CGM in daytime (r=0.76 and nighttime (r=0.82. The optimal cutoff for the IG AUC value of MIET to predict hyperglycemia over 200 mg/dL measured by CGM for 8 hours was 1,067.3 mg·hr/dL with 88.2% sensitivity and 81.5% specificity.ConclusionWe showed that 8-hour IG AUC levels using MIET were valuable in estimating the blood glucose AUC without blood sampling. The results also supported the concept of using this technique for evaluating glucose excursion and for screening hyperglycemia during 8 hours in patients with diabetes at any time of day.

    Is there any relationship between estrogen and progesterone concentrations during assisted reproductive technology (ART)? Which hormone is the main determinant of impaired endometrial receptivity? This study was conducted from July to December 2016 at the in vitro Fertilization/Intracytoplasmic Sperm Injection unit at Zeynep Kamil Women and Children's Health Training and Research Hospital. A total of 289 women who underwent ART were prospectively screened and areas under the curve of temporal estrogen (AUCEM) and progesterone measurements (AUCPM) were calculated for each participant. Women were included if they had regular menstrual cycles, normal serum prolactin levels and had not received hormone treatment within three months. ART was indicated in all patients for unexplained infertility. Patients were divided into two groups: with (n = 90) and without (n = 199) embryo implantation. The relationship between the two AUCs and ART success was assessed in terms of embryo implantation and clinical pregnancy. Implantation was successful in 90 (31.1%) women, and a fetal heart rate was detected in 83 (28.7%) cases. There was a significant correlation between AUCEM and AUCPM (r = 0.525, P < 0.001). Multivariate regression analysis showed significant associations between failure of implantation, lack of clinical pregnancy and AUCEM (beta coefficient = 0.311, P < 0.001; beta coefficient = 0.297, P < 0.001, respectively) after adjusting for AUCPM. Our data showed that the degree of endometrial estrogen exposure is the main factor functioning as a detrimental effect of ovarian stimulation on endometrial receptivity. © 2017 Japan Society of Obstetrics and Gynecology.

    The Hawai'i Undersea Research Laboratory (HURL) is the only U.S. deep submergence facility in the Pacific Rim tasked with supporting undersea research necessary to fulfill the mission, goals, and objectives of the National Oceanic and Atmospheric Administration (NOAA), along with other national interests of importance. Over 30 years of submersible operations have resulted in nearly 1900 dives representing 9300 hours underwater, and a benthic ecology database derived from in-house video record logging of over 125,000 entries based on 1100 unique deep-sea animal identifications in the Hawaiian Archipelago. As a Regional Center within the Office of Ocean Exploration and Research (OER), HURL conducts undersea research in offshore and nearshore waters of the main and Northwestern Hawaiian Islands and waters of the central, southern, and western Pacific. HURL facilities primarily support marine research projects that require data acquisition at depths greater than wet diving methods. These consist of the research vessel Ka'imikai-o-Kanaloa (KOK), human occupied submersibles Pisces IV and Pisces V (2000 m), a new remotely operated vehicle (6000 m), and a multibeam bathymetric sonar system (11,000 m). In addition, HURL has also supported AAUS compliant wet diving since 2003, including technical mixed gas/rebreather work. While ecosystem studies of island, atoll, and seamount flanks are the largest component of the HURL science program, many other thematic research areas have been targeted including extreme and unique environments, new resources from the sea, episodic events to long term changes, and the development of innovative technologies. Several examples of HURL's contributions to marine protected areas (MPAs) include: (a) A long term presence in the pristine ecosystems of the Papahānaumokuākea Marine National Monument in the Northwestern Hawaiian Islands. Researchers from National Marine Fisheries have used HURL assets to study endangered Hawaiian Monk Seal habitat

    With an objective to improve efficiency and reduce cost of CIS-based thin film solar cells, research and development has been made on technologies to increase high-quality CIS film area and technologies to increase speed in the manufacturing process. This paper describes the achievements attained during fiscal 1997. The research covered development of technologies to form high-grade Cu (In, Ga) Se{sub 2} (CIGS) film by using the multi-dimensional deposition process, component technologies for forming a rear electrode, a buffer layer and a transparent electrode, and patterning technologies. As a result of the research, thickness of the CIGS film was reduced to half as much as that of the conventional films, having achieved conversion efficiency of 13.1%, which corresponds to about 90% of the conventional CIGS solar cells. In addition, elucidation was made on the effect of an MoSe{sub 2} layer existing on interface with CIGS/Mo in a CIGS solar cell imposed on solar cell characteristics. In developing an Mo film laser scribing technology, intensity dependence of laser energy was made clear, the energy being required for scribing according to surface condition of the Mo film. (NEDO)

    About 25% of the Indian population experience common mental disorders (CMD) but only 15-25% of them receive any mental health care. Stigma, lack of adequate mental health professionals and mental health services account for this treatment gap, which is worse in rural areas. Our project evaluated task shifting and mobile-technology based electronic decision support systems to enhance the ability of primary care health workers to provide evidence-based mental health care for stress, depression, and suicidal risk in 30 remote villages in the state of Andhra Pradesh, India. The Systematic Medical Appraisal Referral and Treatment (SMART) Mental Health project between May 2014 and April 2016 trained lay village health workers (Accredited Social Health Activists - ASHAs) and primary care doctors to screen, diagnose and manage individuals with common mental disorders using an electronic decision support system. An anti-stigma campaign using multi-media approaches was conducted across the villages at the outset of the project. A pre-post evaluation using mixed methods assessed the change in mental health service utilization by screen positive individuals. This paper reports on the quantitative aspects of that evaluation. Training was imparted to 21 ASHAs and 2 primary care doctors. 5007 of 5167 eligible individuals were screened, and 238 were identified as being positive for common mental disorders and referred to the primary care doctors for further management. Out of them, 2 (0.8%) had previously utilized mental health services. During the intervention period, 30 (12.6%) visited the primary care doctor for further diagnosis and treatment, as advised. There was a significant reduction in the depression and anxiety scores between start and end of the intervention among those who had screened positive at the beginning. Stigma and mental health awareness in the broader community improved during the project. The intervention led to individuals being screened for common mental

    In Italy, health protection is an individual right protected by the article 32 of the Constitution, granted to everyone since 1978 by the foundation of the National Health Service. However, regionalization of the healthcare system has caused noticeable discrepancies among the different areas of the country. The use of the Information and Communication Technology (ICT) may be useful to solve them. The purpose of this document is to analyze the implementation of ICT in Italy, on the basis of the suggestions given by the Italian Association of Hospital Cardiologists (ANMCO). In 2010, the Italian government introduced the electronic health record (EHR), which includes a minimum core of essential documents that should be created and updated by general practitioners. The obvious limitations of this methodology become clear in the urgency-emergency clinical setting, where the availability of particular clinical data may influence both patient prognosis and cost reduction. Also the privacy rules, currently very restrictive, cause a drawback in reliability of the data reported in the EHR, thus arising the need for a balance shift from privacy to health rights at the level of both the individual and the community. A minimum core of mandatory clinical data to be included in the EHR should be defined. No formal indications for filling out the medical records are available and most few experiences concern "bureaucratic documents" on the diagnostic and therapeutic process. Conversely, we believe that medical records should become a diagnostic and therapeutic tool that makes health rights uniform across the country. Each medical record form should include the following features: a simple interface, a mandatory association of clinical findings and reports, data portability and accessibility, and adherence of the information to a minimal dataset. Additionally, medical records data should merge into a modified EHR available at any time and place through network access points with

    Full Text Available Abstract – At present, audiovisual translation is one of the most interesting and stimulating domains within the field of Translation Studies. Resting on a rich semiotic apparatus, marked by the interplay of a double channel of communication – audio/visual – with different types of signs – verbal/non-verbal codes, the audiovisual text is a complex one, whose transfer from one language into another represents a challenging task for every professional in this field. Especially in dubbing, the translator/adapter has to work on the interlinguistic level as well as on the intersemiotic level (iconic, paralinguistic elements, etc.: as many codes having great semantic potential and transmitting useful cultural information, as we shall see in the film which we have taken as the object of our analyses: Astérix et Obélix: Au Service de Sa Majesté (2012. This fourth film adaptation (except cartoons of Astérix’s adventures offers a series of gags playing on the parody of typical traditions, symbols, linguistic clichés and cultural stereotypes associated with British culture. Italian dubbing resorts to different translation strategies, some of which come under a foreignizing approach, aiming at preserving the original’s colour and mood, whereas others are in line with a domesticating approach, in order to bring the product closer to the final audience. Indeed, instead of stressing the idea of a polarization or a dichotomy between two contrasting perspectives, we find it advisable to envisage a gradation between two instances which occur at the same time and coexist in a complementary way during the translation process.   Keywords: audiovisual translation; dubbing; cultural elements; humorous elements; foreignization/domestication.     Résumé – La traduction audiovisuelle se configure à l’heure actuelle comme l’un des domaines les plus intéressants et les plus stimulants dans le panorama des etudes traductologiques.

    The independent living donor advocate (ILDA) serves a mandated and supportive role in the care of the living organ donor, yet qualifications and role requirements are not clearly defined. Guidance comes from Centers for Medicare and Medicaid Services (CMS) Conditions for Transplant Center Participation and interpretive guidelines, Organ Procurement and Transplantation Network (OPTN) Policy and CMS and OPTN site surveys, yet interpretation of regulations varies. Herein, the AST Living Donor Community of Practice (LDCOP) offers seven recommendations to clarify and optimize the ILDA role: (a) the ILDA must have a certain skill set rather than a specific profession, (b) the ILDA must be educated and demonstrate competence in core knowledge components, (c) the ILDA's primary role is to assess components of informed consent, (d) centers must develop a transparent system to define ILDA independence, (e) the ILDA should have a reporting structure outside the transplant center, (f) the ILDA's role should be integrated throughout the donor care continuum, (g) the ILDA role should include a narrow "veto power." We address controversies in ILDA implementation, and offer pathways to maximize benefits and minimize limitations of approaches that may each meet regulatory requirements but confer different practice benefits. We propose a research agenda to explore the impact of the ILDA. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    A search for Higgs boson production in association with a $W$ or $Z$ boson, in the $H \\rightarrow WW^{\\ast}$ decay channel, is performed with a data sample collected with the ATLAS detector at the LHC in proton-proton collisions at centre-of-mass energies $\\sqrt{s}=7$ TeV and 8 TeV, corresponding to integrated luminosities of 4.5 ${\\rm fb}^{-1}$ and 20.3 ${\\rm fb}^{-1}$, respectively. The $WH$ production mode is studied in two-lepton and three-lepton final states, while two-lepton and four-lepton final states are used to search for the $ZH$ production mode. The observed significance, for the combined $WH$ and $ZH$ production, is 2.5 standard deviations while a significance of 0.9 standard deviations is expected in the Standard Model Higgs boson hypothesis. The ratio of the combined $WH$ and $ZH$ signal yield to the Standard Model expectation, $\\mu_{VH}$, is found to be $\\mu_{VH} =3.0^{+1.3}_{-1.1}{\\, {(\\rm stat.)}}^{+1.0}_{-0.7}{\\,{(\\rm sys.)}}$ for the Higgs boson mass of 125.36 GeV. The $WH$ and $ZH$ produc...

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology '90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology '90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information. Separate papers were prepared for appropriate sections of this report

    We investigated the association between significant liver fibrosis, determined by AST-to-platelet ratio index (APRI), and all-cause mortality among HIV-infected patients prescribed antiretroviral therapy (ART) in Zambia. Among HIV-infected adults who initiated ART, we categorized baseline APRI scores according to established thresholds for significant hepatic fibrosis (APRI ≥1.5) and cirrhosis (APRI ≥2.0). Using multivariable logistic regression we identified risk factors for elevated APRI including demographic characteristics, body mass index (B
