    Full Text Available Syphilis is one of the most fascinating diseases of humans. Widespread use of antibiotics now has reduced the incidence of early syphilis and recognized new cases of late syphilis have decreased. Serological tests are the basis for the diagnosis of latent syphilis. They vary in their sensitivity and specificity. While non-treponemal tests (VDRL and RPR are most frequently used as screening procedures, treponemal tests (FTA-ABS and TPHA are considered to be highly sensitive and specific. MATERIALS AND METHODS In this study 100 serum samples collected from the patients attending STD Department, King George Hospital, Visakhapatnam. Samples were subjected to VDRL, RPR and Micro-TPHA tests to evaluate the sensitivity and specificity of Micro-TPHA test in patients with various stages of syphilis and to evaluate the efficacy of Micro-TPHA to confirm the diagnosis of syphilis and to rule out biological false positive reactions or false negative reactions of VDRL tests. RESULTS Three tests (VDRL, RPR and Micro-TPHA were applied to all 100 patients. Among them 85 were VDRL reactive, 84 were RPR positive and 89 were TPHA positive. In them males were more in number, in 3 tests with respect to age, (21-30 age group patients showed predominance. Out of 100 patients, 81 sera were positive for all three tests and one serum sample was VDRL reactive, but RPR and TPHA were non-reactive. This may be a false positive reaction. The following tables showed the sensitivity and specificity of each test and also the sensitivity of each test in various stages of syphilis. CONCLUSION It is concluded as by performing TPHA test, false positive reactivity of VDRL test could be detected. Even in the cases of treated primary and secondary syphilis, TPHA was reactive. The lipoidal antigen tests primarily reflect disease activity and serial quantitative performance of these tests used to measure the treatment response.

    1983-01-01

    The treponemal haemagglutination (THA) test has been used for 11 years as a routine test for syphilis at a central serology laboratory. Among patients with untreated early syphilis the antibodies detected by the THA test usually appeared later or were of relatively lower titre than those detected by the reagin tests. This finding was confirmed by follow up of patients and by replies to questionnaires and has been incorporated in a computer program. During 1981, using the results obtained on u...

    Full Text Available Systemic lupus erythematosus (SLE is a connective tissue disease characterized by vasculitis, which may involve multiple organs as well as the skin. Serologic tests for syphilis may be false positive in SLE. Although the false positivity of VDRL (Venereal Disease Research Laboratory is commonly seen, false positivity of TPHA (Treponema pallidum haemagglutination is a rare condition. We present a case of SLE with false positive VDRL and TPHA. A 26-year-old woman was admitted to our clinic with violaceous papules and plaques with whitish desquamation and erosions, and crusts on the face, arms and back. The histopathological examination of the skin biopsy supported the diagnosis of discoid lupus erythematosus. The diagnosis of SLE was based on the presence of photosensitivity and the detection of leukopenia, anemia and positivities of antinuclear antibody, anti DNA, and VDRL. In addition to these findings, TPHA was found to be positive, but the ELISA test for syphilis and FTA ABS Ig M were negative. The positivity of VDRL and TPHA were accepted as false positives. We would like to point out that the false positivity of TPHA, although more rarely encountered, as well as that of VDRL, may be observed in SLE patients.

    2013-01-01

    In support of the development of the J-2X engine, 201 low pressure, liquid oxygen / liquid hydrogen (LOX/LH2) J-2X Augmented Spark Igniter (ASI) subsystem ignition tests were conducted at Marshall Space Flight Center (MSFC). The main objective of these tests was to start the ASI within the anticipated J-2X engine start box, as well as outside of it, to check for ignition margin. The setup for the J-2X ASI component testing simulated, as much as possible, the tank-head start-up configuration of the ASI within the J-2X Engine. The ignition tests were divided into 124 vacuum start tests to simulate altitude start on a flight engine, and 77 sea-level start tests to simulate the first set of ground tests for the J-2X Engine at Stennis Space Center (SSC). Other ignition parameters that were varied included propellant tank pressures, oxidizer temperature entering the ASI oxidizer feedline, oxidizer valve timing, spark igniter condition (new versus damaged), and oxidizer and fuel feedline orifice sizes. Propellant blowdowns using venturis sized to simulate the ASI resistance allowed calculation of transient propellant mass flow rates as well as global mixture ratio for all ignition tests. Global mixture ratio within the ASI at the time of ignition varied from 0.2 to 1.2. Detailed electronics data obtained from an instrumented ignition lead allowed characterization of the breakdown voltage, sustaining voltage and energy contained in each spark as the ASI propellants ignited. Results indicated that ignition always occurred within the first five sparks when both propellants were present in the ASI chamber.

    Reliable operation of the spark ignition system electronics in the J-2X Augmented Spark Igniter (ASI) is imperative in assuring ASI ignition and subsequent Main Combustion Chamber (MCC) ignition events are reliable in the J-2X Engine. Similar to the man-rated J-2 and RS-25 engines, the J-2X ignition system electronics are equipped with spark monitor outputs intended to indicate that the spark igniters are properly energized and sparking. To better understand anomalous spark monitor data collected on the J-2X development engines at NASA Stennis Space Center (SSC), a comprehensive subsystem study of the engine's low- and high-tension spark ignition system electronics was conducted at NASA Marshall Space Flight Center (MSFC). Spark monitor output data were compared to more detailed spark diagnostics to determine if the spark monitor was an accurate indication of actual sparking events. In addition, ignition system electronics data were closely scrutinized for any indication of an electrical discharge in some location other than the firing tip of the spark igniter - a problem not uncommon in the development of high voltage ignition systems.

    In this paper, the second in a series, we document the algorithms and solvers for compressible nonrelativistic hydrodynamics implemented in GenASiS (General Astrophysical Simulation System)---a new code being developed initially and primarily, though by no means exclusively, for the simulation of core-collapse supernovae. In the Mathematics division of GenASiS we introduce Solvers, which includes finite-volume updates for generic hyperbolic BalanceEquations and ordinary differential equation integration Steps. We also introduce the Physics division of GenASiS; this extends the Manifolds division of Mathematics into physical Spaces, defines StressEnergies, and combines these into Universes. We benchmark the hydrodynamics capabilities of GenASiS against many standard test problems; the results illustrate the basic competence of our implementation, demonstrate the manifest superiority of the HLLC over the HLL Riemann solver in a number of interesting cases, and provide preliminary indications of the code's abili...

    Carlos, W. E.; Taylor, P. C.

    1982-10-01

    Results of pulsed NMR studies of hydrogen in a-Si: H prepared at several laboratories by glow discharge of silane are presented. The origins of the two 1H NMR lines seen in almost all samples of a-Si: H are discussed. Solid-echo measurements are presented which indicate that these two components are due to spatially isolated groups of protons. We attribute the narrow line to protons slightly clustered in the bulk of the material and the broad line to protons distributed on internal surfaces. The spin-lattice relaxation time shows a minimum at T~30 K which is interpreted as due to relaxation via spin diffusion to a small number of H2 molecules acting as relaxation centers. Annealing results suggest that all the hydrogen molecules are trapped in very similar sites.

  13. Modeling of SSME fuel preburner ASI

    1992-07-01

    The Augmented Spark Ignitor (ASI) is a LOX/H2/electrical spark system that functions as an ignition source and sustainer for stable combustion. It is used in the Space Shuttle Main Engine (SSME) preburner combustor, the SMME main combustion chamber, the J-1 and J-2 engines, as well as proposed designs of the Space Transportation Main Engine (STME) main combustor and gas generators. An undertaking to characterize the flow of the ASI is documented. The code consists of a marriage of the Implicit-Continuous Eulerian/Arbitrary Lagrangian Code (ICE-ALE) Navier-Stokes solver with the Volume-of-Fluid (VOF) Methodology for tracking of two immiscible fluids with sharp discontinuities. Spray droplets are represented by discrete numerical parcels tracked in a Lagrangian fashion. Numerous physical sub-models are also incorporated to describe the processes of atomization, droplet collision, droplet breakup, evaporation, and droplet and gas phase turbulence. An equilibrium chemistry model accounting for 8 active gaseous species is also used. Taking advantage of this symmetry plane, half of the actual ASI is modeled with a 3-D grid that geometrically resolves the LOX ports, the spark plug locations, and the hydrogen injection slots.

    This study demonstrates a method for alternating current (AC) susceptibility imaging (ASI) of magnetic nanoparticles (mNPs) using low cost instrumentation. The ASI method uses AC magnetic susceptibility measurements to create tomographic images using an array of drive coils, compensation coils and fluxgate magnetometers. Using a spectroscopic approach in conjunction with ASI, a series of tomographic images can be created for each frequency measurement set and is termed sASI. The advantage of sASI is that mNPs can be simultaneously characterized and imaged in a biological medium. System calibration was performed by fitting the in-phase and out-of-phase susceptibility measurements of an mNP sample with a hydrodynamic diameter of 100 nm to a Brownian relaxation model (R{sup 2}=0.96). Samples of mNPs with core diameters of 10 and 40 nm and a sample of 100 nm hydrodynamic diameter were prepared in 0.5 ml tubes. Three mNP samples were arranged in a randomized array and then scanned using sASI with six frequencies between 425 and 925 Hz. The sASI scans showed the location and quantity of the mNP samples (R{sup 2}=0.97). Biological compatibility of the sASI method was demonstrated by scanning mNPs that were injected into a pork sausage. The mNP response in the biological medium was found to correlate with a calibration sample (R{sup 2}=0.97, p<0.001). These results demonstrate the concept of ASI and advantages of sASI. - Highlights: • Development of an AC susceptibility imaging model. • Comparison of AC susceptibility imaging (ASI) and susceptibility magnitude imaging (SMI). • Demonstration of ASI and spectroscopic ASI (sASI) using three different magnetic nanoparticle types. • SASI scan separation of three different magnetic nanoparticles samples using 5 spectroscopic frequencies. • Demonstration of biological feasibility of sASI.

    Background and Objectives: Biological false positive (BFP) reactivity by the Venereal Disease Research Laboratory (VDRL) test used for diagnosis of syphilis is a cause for concern. The use of the VDRL as a screening procedure is challenged by some studies. The aim of this study is to determine the prevalence of BFP reactions in different subject groups and to assess the usefulness of Treponema pallidum hemagglutination (TPHA) test in low titre VDRL reactive sera. Materials and Methods: A total of 5785 sera from sexually transmitted diseases (STD) clinic attendees, antenatal clinic attendees, husbands of antenatal cases, peripheral health centres attendees (representing community population) and from patients referred from different OPDs/wards were screened for BFP reactions by the VDRL test. Sera reactive in the VDRL test were confirmed by the TPHA test. Results: Out of 80 qualitative VDRL reactive sera, 68 had <1:8 titre on quantitation and TPHA was positive in 59 samples, indicating BFP reactivity in 0.2% in all the subject groups. BFP was nil in the community population. The male-to-female ratio of BFP reactions was 2:1. VDRL and TPHA positivity was highest (76%) in the age group of 20-29 years. The seroprevalence of syphilis varied from 0.4% to 3.5% in different patient groups. Conclusions: The results of this study highlight that the TPHA positivity was high (86.8%) in sera with VDRL titre less than 1:8. Therefore, for the diagnosis of syphilis, it is recommended that a confirmatory test such as TPHA should be performed on all sera with a reactive VDRL regardless of its titre. PMID:23188934

  3. Compensator thickness verification using an a-Si EPID

    International Nuclear Information System (INIS)

    Electronic portal imaging devices (EPIDs) are being increasingly employed to make therapy verification and dose measurements in the clinic. In this work, we investigate the use of an amorphous silicon (a-Si) EPID to verify the accuracy of compensator fabrication and mounting. Compensator thickness estimates on a two-dimensional grid were calculated from the primary component of transmission obtained by subtracting a modeled scatter component from the total transmission measured with the EPID. The primary component was related to the thickness via an exponential relation that includes beam hardening. Implementation of the method involved determination of: (i) a calibration curve relating EPID pixel values to energy fluence for open and attenuated fields, which was found to be linear for open fields but to have a small quadratic component for attenuated beams; (ii) EPID scatter factors to account for field size effects, which exhibited a small dependence on compensator thickness and field size; (iii) the attenuation coefficient of the steel shot compensator material, which varied slightly with off-axis distance and field size, and (iv) an analytical model to predict scatter from the compensator, which was calculated to be <4% at the standard EPID imaging distance of 140 cm. Thickness distributions were then measured for several types of attenuators including flat, test, and clinical compensators. Although uncertainties associated with compensator manufacturing were non-negligible and made assessment of thickness measurement uncertainty difficult, we estimate the latter to be ∼0.5 mm for steel shot compensators of thickness <4 cm

    Full Text Available The non-Treponemal tests such as Rapid Plasma Reagin test (RPR or the Venereal Disease Reference Laboratory test are the most commonly used test for screening of syphilis in the blood centers in India. Now, with the availability of Enzyme-linked immunosorbent assay (ELISA and Immunochromatographic assays in the market, we decided to evaluate these assays in comparison with Treponema pallidum Haemagglutination Assay (TPHA which was considered as a gold standard for this study. A total of 8 685 samples of voluntary blood donors were tested on Trepolisa 3.0 and then the initially reactive samples were retested in duplicate on the same assay as well as on Omega Pathozyme, RPR, RAPHA (Rapid Anti-Treponema pallidum Assay, and TPHA. Of the 158 initially reactive samples, 104 were repeatedly reactive on the same assay, 85 were reactive with RPR, 77 were reactive with RAPHA, 60 were reactive on Omega, and 53 were confirmed reactive on TPHA. 48 (56.4% of the results on RPR were biological false positive, while 21.9% of results were false negative on RPR. We evaluated that Omega Pathozyme was quite in agreement with TPHA as compared with Trepolisa 3.0, RAPHA, and RPR. We concluded that Omega Pathozyme (ELISA can be considered as a suitable test for screening of syphilis in a blood center.

    Portal imaging by amorphous silicon (aSi) photodiode is currently the most applied technology for in-vivo dosimetry (IVD) of static and dynamic radiotherapy beams. The strategy, adopted in this work to perform the IVD procedure by aSi EPID, is based on: in patient reconstruction of the isocenter dose and day to day comparison between 2D-portal images to verify the reproducibility of treatment delivery. About 20.000 tests have been carried out in this last 3 years in 8 radiotherapy centers using the SOFTDISO program. The IVD results show that: (i) the procedure can be implemented for linacs of different manufacturer, (ii) the IVD analysis can be obtained on a computer screen, in quasi real time (about 2 min after the treatment delivery) and (iii) once the causes of the discrepancies were eliminated, all the global IVD tests for single patient were within the acceptance criteria defined by: ±5% for the isocenter dose, and P{sub γ<1}≥90% of the checked points for the 2D portal image γ-analysis.

    Since nineties Italian Space Agency (ASI), Centre National d'Etudes Spatiales CNES and Japan Aerospace Exploration Agency (JAXA) play an important role in Inter-Agency Space Debris Coordination Committee (IADC) activities. Respectively the Group of Astrodynamics of Uni-versity Sapienza of Rome (GAUSS), TAROT team (Télescope a Action Rapide pour les Objets Transitoires) and Institute of Aerospace Technology (IAT), participate in optical space debris monitoring activities (WG1 at IADC ) with the following facilities: 1. SpaDE observatory of ASI/GAUSS in Collepardo (Fr.), country-regionplaceItaly. 2. TAROT observatories of CNES: one in Chili (ESO LA Silla) and one in placecountry-regionFrance (Observatoire de la Côte d'Azur, at Calern). 3. Nyukasayama Observatory of IAT/JAXA, country-regionplaceJapan. Due to the large amount of data collected during the IADC coordinated observation campaigns and the autonomous campaigns, these research groups developed three different software for image processing automation and for the correlation of the detected objects with the catalogue. Using these software the three different observatories are improving the knowledge of the space debris population, in particular in the so-called geostationary belt (AI23.4 IADC International 2007 optical observation campaigns in higher Earth orbits and AI23.2 Investigation of high A/m ratio debris in higher Earth orbits), but they use different space debris monitoring techniques. With the aim to improve CCD analysis capabilities of each research group, during the 27th IADC meeting ASI, CNES and JAXA started a cooperation in this field on the comparison between the image processing software. The objectives of this activity are: 1. Test of ASI, CNES and JAXA CCD analysis software on real images taken in the 3 dif-ferent observation strategies (each observatory uses a particular objects extraction pro-cedure). 2. Results comparison: number of bad detection, number of good detection, processing

    Full Text Available Background and Objectives: Syphilis is one of the most common preventable causes of adverse effects during pregnancy. Antenatal screening prevents the delay between diagnosis and treatment there by reducing the risk of congenital syphilis. The objective of this study was to evaluate the utility of an immunochromatographic assay as a point of care test for antenatal screening of syphilis. Materials and Methods: Sera of 200 antenatal mothers were evaluated for serodiagnosis of syphilis by the venereal disease research laboratory (VDRL, Treponema pallidum hemagglutination assay (TPHA and SD BIOLINE Syphilis 3.0 test. The performance of SD BIOLINE Syphilis 3.0 test was compared with VDRL as screening assay and TPHA as a confirmatory test. Results: The antenatal prevalence of syphilis was found to be 2% by both VDRL and TPHA. The sensitivity, specificity, positive predictive value, and the negative predictive value of SD BIOLINE Syphilis 3.0 test were 75%, 100%, 100%, and 99.45%, respectively. Conclusions: Antenatal screening and treatment of maternal syphilis are cost-effective health interventions even under the low prevalence of infection. SD BIOLINE Syphilis 3.0 test, although having less sensitivity than the existing testing strategy, can have a tremendous impact on the disease burden if used prudently for the screening of antenatal mothers in peripheral health settings.

  16. GenASiS Basics: Object-oriented utilitarian functionality for large-scale physics simulations

    Aside from numerical algorithms and problem setup, large-scale physics simulations on distributed-memory supercomputers require more basic utilitarian functionality, such as physical units and constants; display to the screen or standard output device; message passing; I/O to disk; and runtime parameter management and usage statistics. Here we describe and make available Fortran 2003 classes furnishing extensible object-oriented implementations of this sort of rudimentary functionality, along with individual `unit test' programs and larger example problems demonstrating their use. These classes compose the Basics division of our developing astrophysics simulation code GenASiS (General Astrophysical Simulation System), but their fundamental nature makes them useful for physics simulations in many fields.

    GenASiS (General Astrophysical Simulation System) is a new code being developed initially and primarily, though by no means exclusively, for the simulation of core-collapse supernovae on the world's leading capability supercomputers. Using the features of Fortran 2003 that allow for object-oriented programming, its classes are grouped into three major divisions: (1) Basics, which contains some basic utilitarian functionality for large-scale simulations on distributed-memory supercomputers; (2) Mathematics, which includes generic mathematical constructs and solvers that are as agnostic as possible with regard to the specifics of any particular system; and (3) Physics, which sets up physical spaces associated with various theories of spacetime (including gravity), defines various forms of stress-energy, and combines these into `universes.' To provide a foundation for subsequent papers focusing on the implementation of various pieces of physics needed for the simulation of core-collapse supernovae and other astr...

    Activated factor VII blocked in the active site with Phe-Phe-Arg-chloromethyl ketone (active site inhibited factor VII (ASIS)) is a 50-kDa protein that binds with high affinity to its receptor, tissue factor (TF). TF is a transmembrane glycoprotein that plays an important role in, for example, thrombosis, metastasis, tumor growth, and tumor angiogenesis. The aim of this study was to develop an (18)F-labeled ASIS derivative to assess TF expression in tumors. Active site inhibited factor VII was labeled using N-succinimidyl-4-[(18)F]fluorobenzoate, and the [(18)F]ASIS was purified on a PD-10 desalting column. The radiochemical yield was 25 ± 6%, the radiochemical purity was >97%, and the pseudospecific radioactivity was 35 ± 9 GBq/µmol. The binding efficacy was evaluated in pull-down experiments, which monitored the binding of unlabeled ASIS and [(18)F]ASIS to TF and to a specific anti-factor VII antibody (F1A2-mAb). No significant difference in binding efficacy between [(18)F]ASIS and ASIS could be detected. Furthermore, [(18)F]ASIS was relatively stable in vitro and in vivo in mice. In conclusion, [(18)F]ASIS has for the first time been successfully synthesized as a possible positron emission tomography tracer to image TF expression levels. In vivo positron emission tomography studies to evaluate the full potential of [(18)F]ASIS are in progress. PMID:25820758

  2. Structural properties of a-Si films and their effect on aluminum induced crystallization

    International Nuclear Information System (INIS)

    In this paper, we report the influence of the structural properties of amorphous silicon (a-Si) on its subsequent crystallization behavior via the aluminum induced crystallization (AIC) method. Two distinct a-Si deposition techniques, electron beam evaporation and plasma enhanced chemical vapor deposition (PECVD), are compared for their effect on the overall AIC kinetics as well as the properties of the final poly-crystalline (poly-Si) silicon film. Raman and FTIR spectroscopy results indicate that the PECVD grown a-Si films has higher intermediate-range order, which is enhanced for increased hydrogen dilution during deposition. With increasing intermediate-range order of the a-Si, the rate of AIC is diminished, leading larger poly-Si grain size

    International Nuclear Information System (INIS)

    Electrochemical etching of amorphous SiC in fluoride solution was studied. Anodic dissolution and passivation are observed for p-type electrodes under dark illumination. The dissolution of p-type a-Si1-xCx is found to be under mixed transport/kinetic control; the diffusion current is of first order in fluoride concentration. Porous etching was not observed in this case. The surface finish of 6H-SiC depends on the experimental conditions; both uniform and porous etching is observed. In this paper, we report the formation of porous p-type amorphous SiC (a-Si1-xCx) films, elaborated previously by DC magnetron sputtering and analyze the porous layers (PSC) using scanning electron microscopy, spectrophotometer and photoluminescence. The crystal structures and the preparation conditions of porous SiC are shown to have an effect on the structural and electrical properties of the material obtained. SEM observation indicates that the porous a-Si1-xCx layers have shown some specific feature; a semi-cylindrical structure of the porous network has been observed. - Research highlights: →Macroporous amorphous silicon carbide (PSC) by anodization. →Membrane of amorphous silicon carbide by KOH etching. → Membrane a-Si1-xCx and PSC for humidity sensors.

    The number of photovoltaic (PV) system installations is increasing rapidly. As more people learn about this versatile and often cost-effective power option, this trend will accelerate. This document presents a recommended design for a battery based stand-alone photovoltaic system (BSPV). BSPV system has the ability to be applied in different areas, including warning signals, lighting, refrigeration, communication, residential water pumping, remote sensing, and cathodic protection. The presented calculation method gives a proper idea for a system sizing technique. Based on application load, different scenarios are possible for designing a BSPV system. In this study, a battery based stand-alone system was designed. The electricity generation part is three a-Si panels, which are connected in parallel, and for the storage part LFP (lithium iron phosphate) battery was used. The high power LFP battery packs are 40 cells each 8S5P (configured 8 series 5 parallel). Each individual pack weighs 0.5 kg and is 25.6 V. In order to evaluate the efficiency of a-Si panels with respect to the temperature and the solar irradiation, cities of Istanbul, Ankara and Adana in Turkey were selected. Temperature and solar irradiation were gathered from reliable sources and by using translation equations, current and voltage output of panels were calculated. As a result of these calculations, current and energy outputs were computed by considering an average efficient solar irradiation time value per day in Turkey. The calculated power values were inserted to a battery cycler system, and the behavior of high power LFP batteries in a time sequence of 7.2 h was evaluated. The charging and discharging cycles were obtained and their behavior was discussed. According to the results, Istanbul has the lowest number of peak month's energy, it followed by Ankara, and ultimately Adana has the highest number of peak months and energy storage. It was observed during the tests that values up to 4 A was

    In order to achieve successful clinical outcomes, biomaterials used for bone grafts must possess a number of traits including biocompatibility and osteoconductivity. These materials must also demonstrate appropriate mechanical stability to withstand handling as well as support potentially significant stresses at the implant site. Synthetic and natural polymer scaffolds used for bone tissue engineering (BTE) often lack necessary mechanical properties. Our goal was to internally mineralize natural collagenous matrix, thereby increasing mechanical properties of the material to useful levels. Published methods for intrafibrillar collagen mineralization were applied to clinically relevant-sized constructs but did not successfully deposit mineral in the interior of the constructs. To address this limitation, we developed a new technique for the remineralization of demineralized bone matrix (DBM) based on alternating solution immersion, or ASI. Mineral was removed from equine bone specimens, leaving behind a demineralized bone matrix (DBM). This matrix provides a framework for the nucleation and growth of a replacement mineral phase. Plain film radiography and microcomputed tomography (microCT) indicated accumulation of mineral within the DBM, and mechanical testing (3 point bending and compression) revealed a significant increase in stiffness between the DBM and the remineralized bone matrix (RBM). We believe this remineralization process will be useful in the preparation of stiff and strong allografts for clinical application. PMID:23759125

Based on 89 GHz AMSR-E (Advanced Microwave Scanning Radiometer for Earth Observing System) data, a gridded high-resolution passive microwave sea ice concentration product can be obtained using the ASI (the Arctic Radiation And Turbulence Interaction Study (ARTIST) Sea Ice) retrieval algorithm. Instead of using fixed-point values, we developed ASI algorithm based on daily changed tie points, called as the dynamic tie point ASI algorithm in this study. Here the tie points are expressed as the brightness temperature polarization difference of open water and 100% sea ice. In 2010, the yearly-averaged tie points of open water and sea ice in Arctic are estimated to be 50.8 K and 7.8 K, respectively. It is confirmed that the sea ice concentrations retrieved by the dynamic tie point ASI algorithm can increase (decrease) the sea ice concentrations in low-value (high-value) areas. This improved the sea ice concentrations by present retrieval algorithm from microwave data to some extent. Comparing with the products using fixed tie points, the sea ice concentrations retrieved from AMSR-E data by using the dynamic tie point ASI algorithm are closer to those obtained from MODIS (Moderate-resolution Imaging Spectroradiometer) data. In 40 selected cloud-free sample regions, 95% of our results have smaller mean differences and 75% of our results have lower root mean square (RMS) differences compare with those by the fixed tie points.

  11. Magnetism of Mn doped in a-Si and a-Ge

    With experimental studies and density function theory calculations, we report on the properties of Mn-doped amorphous Si and Ge which are designed to understand the fundamentals of cooperative phenomena in highly correlated electronic and magnetic systems. We observed a striking difference in Mn local moment when doped in a-Si and a-Ge matrices, in great contrast to the previous speculation that these two should behave very similar as the semiconductor host for transition metals. While we observed a large local moment of Mn in a-Ge, Mn moment is quenched in a-Si. The large difference of local magnetic moment of Mn in a-Si and a-Ge can be understood by the local atomic environment at the magnetic dopant sites, that is, the bond length and the coordination. Statistical DFT calculations shows that the magnetic dopant Mn with less coordination and large bond length hold large magnetic moment. Otherwise, the magnetic moment would be killed. In a-Ge, dopant Mn favours less coordination and large bond while more coordination and small bond length in a-Si, which result in the enhancement/quenchement of local magnetic moment Mn in a-Si/ a-Ge.

    ASI (breast milk) is the best food given by a mother to her new-born baby and the most important one in the first months of a baby’s life which can give protection for infection. The decrease in ASI production in the first days can be caused by the lack of the stimulus of oxytocin and prolactin hormones which play their role in expediting ASI production. One of the techniques to stimulate ASI production is by performing oxytocin message. Its implementation cannot be done by ...

    A technique for performing accelerated stress tests of large-area thin a-Si solar cells is presented. A computer-controlled short-interval test system employing low-cost ac-powered ELH illumination and a simulated a-Si reference cell (seven individually bandpass-filtered zero-biased crystalline PIN photodiodes) calibrated to the response of an a-Si control cell is described and illustrated with flow diagrams, drawings, and graphs. Preliminary results indicate that while most tests of a program developed for c-Si cells are applicable to a-Si cells, spurious degradation may appear in a-Si cells tested at temperatures above 130 C.

  2. Analytic solutions for links and triangles distributions in finite Barab\\'asi-Albert networks

    2016-01-01

    Barab\\'asi-Albert model describes many different natural networks, often yielding sensible explanations to the subjacent dynamics. However, finite size effects may prevent from discerning among different underlying physical mechanisms and from determining whether a particular finite system is driven by Barab\\'asi-Albert dynamics. Here we propose master equations for the evolution of the degrees, links and triangles distributions, solve them both analytically and by numerical iteration, and compare with numerical simulations. The analytic solutions for all these distributions predict the network evolution for systems as small as 100 nodes. The analytic method we developed is applicable for other classes of networks, representing a powerful tool to investigate the evolution of natural networks.

  3. Dispersive transport in hydrogenated a-Si prepared by rf sputtering

    International Nuclear Information System (INIS)

    Time-of-flight measurement of photo-excited carriers has been carried out in hydrogenated a-Si deposited by rf sputtering method. Both electrons and holes show highly dispersive transport. The electron drift mobility near room temperature ranges from 5 x 10-3 to 4 x 10-5 cm2/V.s, much lower than that of GD samples, and the activation energy is about 0.3 eV. The value of the hole mobility is comparable with that in GD specimens, but its activation energy is about 0.2 eV which is about half of that observed in GD a-Si. (author)

  4. Ultra fast melting process in femtosecond laser crystallization of thin a-Si layer

    International Nuclear Information System (INIS)

    In this paper, we investigated the mechanism of crystallization induced by femtosecond laser irradiation for an amorphous Si (a-Si) thin layer on a crystalline Si (c-Si) substrate. The fundamental, SHG, THG wavelength of a Ti:Sapphire laser was used for the crystallization process. To investigate the processed areas we performed Laser Scanning Microscopy (LSM), Transmission Electron Microscopy (TEM) and Imaging Pump-Probe measurements. Except for 267 nm femtosecond laser irradiation, the crystallization occurred well. The threshold fluences for the crystallization using 800 nm and 400 nm femtosecond laser irradiations were 100 mJ/cm2 and 30 mJ/cm2, respectively. TEM observation revealed that the crystallization occurred by epitaxial growth from the boundary surface between the a-Si layer and c-Si substrate. The melting depths estimated by Imaging Pump-Probe measurements became shallower when the shorter wavelength was used.

    Full Text Available Os acordos preferenciais de comércio têm crescido no Pacífico Asiático desde 1998, após a crise financeira que atingiu aquela região. Esse crescimento do número de áreas de comércio é chamado de Novo Regionalismo Asiático. Este artigo apresenta essa nova onda de integração econômica na região, focalizando o comércio, cujas características são: a participação em negociações comerciais de países que antes não eram membros de áreas preferenciais de comércio; os países serem membros de mais de um acordo de comércio regional; muitos dos acordos em negociação cruzarem regiões do mundo e muitos dos novos acordos serem bilaterais. São apresentados os conceitos e a classificação das diferentes formas de integração econômica, os benefícios e as limitações que os acordos preferenciais de comércio trazem às economias; em seguida, são analisadas as áreas de integração econômica existentes e as que estão em processo de negociação na região do Pacífico Asiático. São examinadas, também, as principais causas do Novo Regionalismo Asiático: além da crise asiática, a perda da credibilidade de organismos regionais e do sistema multilateral de comércio, a ampliação das áreas preferenciais de comércio em outras regiões do mundo e a competição de natureza econômica e política entre os países da região. Conclui-se que, se efetivamente houver a integração entre as economias, haverá um novo ciclo de crescimento da economia asiática, em particular do Leste e do Sudeste Asiáticos, prosseguindo com o modelo de crescimento liderado pelas exportações.Preferential trade agreements have been grown in Asia Pacific since 1998, hence after this region faced financial crisis.

    Electronic portal imaging devices (EPIDs) are not only applied for patient setup verification and detection of organ motion but are also increasingly used for dosimetric verification. The aim of our work is to obtain accurate dose distributions from a commercially available amorphous silicon (a-Si) EPID for transit dosimetry applications. For that purpose, a global calibration model was developed, which includes a correction procedure for ghosting effects, field size dependence and energy dependence of the a-Si EPID response. In addition, the long-term stability and additional buildup material for this type of EPID were determined. Differences in EPID response due to photon energy spectrum changes have been measured for different absorber thicknesses and field sizes, yielding off-axis spectrum correction factors based on transmission measurements. Dose measurements performed with an ionization chamber in a water tank were used as reference data, and the accuracy of the dosimetric calibration model was determined for a large range of treatment conditions. Gamma values using 3% as dose-difference criterion and 3 mm as distance-to-agreement criterion were used for evaluation. The field size dependence of the response could be corrected by a single kernel, fulfilling the gamma evaluation criteria in case of virtual wedges and intensity modulated radiation therapy fields. Differences in energy spectrum response amounted up to 30%-40%, but could be reduced to less than 3% using our correction model. For different treatment fields and (in)homogeneous phantoms, transit dose distributions satisfied in almost all situations the gamma criteria. We have shown that a-Si EPIDs can be accurately calibrated for transit dosimetry purposes. PMID:17985633

Researchers deposited wide-bandgap a-Si films using high hydrogen dilution; investigated the deposition of the ZnO layer (for use in back-reflector) using a sputter deposition process involving metal Zn targets; and obtained a baseline fabrication for single-junction a-Si n-i-p devices with 10.6% initial efficiency and a baseline fabrication for triple-junction a-Si devices with 11.2% initial efficiency. ECD researchers also optimized the deposition parameters for a-SiGe with high Ge content; designed a novel structure for the p-n tunnel junction (recombination layer) in a multiple-junction solar cell; and demonstrated, in n-i-p solar cells, the improved stability of a-Si:H:F materials when deposited using a new fluorine precursor. Researchers investigated the use of c-Si(n{sup +})/a-Si alloy/Pd Schottky barrier device as a tool for the effective evaluation of photovoltaic performance on a-Si alloy materials. Through alterations in the deposition conditions and system hardware, researchers improved their understanding for the deposition of uniform and high-quality a-Si and a-SiGe films over large areas. ECD researchers also performed extensive research to optimize the deposition process of the newly constructed 5-MW back-reflector deposition machine.

  19. Structural and optical properties of a-Si1-xCx:H films synthesized by dc magnetron sputtering technique

    International Nuclear Information System (INIS)

    Hydrogenated amorphous SiC films (a-Si1-xCx:H) were prepared by dc magnetron sputtering technique on p-type Si(1 0 0) and corning 9075 substrates at low temperature, by using 32 sprigs of silicon carbide (6H-SiC). The deposited a-Si1-xCx:H film was realized under a mixture of argon and hydrogen gases. The a-Si1-xCx:H films have been investigated by scanning electronic microscopy equipped with an EDS system (SEM-EDS), X-ray diffraction (XRD), secondary ions mass spectrometry (SIMS), Fourier transform infrared spectroscopy (FTIR), UV-vis-IR spectrophotometry, and photoluminescence (PL). XRD results showed that the deposited film was amorphous with a structure as a-Si0.80C0.20:H corresponding to 20 at.% carbon. The photoluminescence response of the samples was observed in the visible range at room temperature with two peaks centred at 463 nm (2.68 eV) and 542 nm (2.29 eV). In addition, the dependence of photoluminescence behaviour on film thickness for a certain carbon composition in hydrogenated amorphous SiC films (a-Si1-xCx:H) has been investigated.

    @@ We present the fabrication and characterization of a novel uncooled infrared sensor for room-temperature infrared imaging. The sensitive element of the sensor is a freestanding amorphous silicon thin film transistor (a-Si TFT)with the temperature coefficient of the drain current (TCC) of 0.015-0.08/K. The TCC value is sensitive to the ambient temperature and can be controlled by the gate voltage of the a-Si TFT. The complete procedures based on the porous silicon micromachining technique for fabricating thermally isolated air bridges are described. The isolation structures have a thermal conductance of 5 × 10-6 W/K and a thermal capacitance of 4.9 × 10-8 J/K.The effects of the gate voltage on the performance figures such as responsivity, noise voltage and detectivity are described and analysed in detail. The maximum detectivity reaches 4.33 × 108 cmHz1/2W-1 at a chopping frequency of 27Hz and a gate voltage of-15 V.

Según este modelo, las poblaciones amerindias poseen un ancestro básico de tipo mongoloide, con diferenciaciones secundarias originadas por procesos microevolutivos locales. Toda comparación basada en distancias o en componentes funcionales, debería entonces sostener la hipótesis: "las distribuciones amerindias se deben aproximar en mayor grado a las de las poblaciones asiáticas y en menor grado a las de las poblaciones europeas". Por componer los araucanos una distribución tipicamente amerindia, debe esperarse entonces que presenten mayor similitud morfológica con grupos asiáticos mongolizados y secundariamente, afinidades con grupos de extracción no mongoloide, dadas estas últimas por procesos evolutivos de adaptación o mestizaje.

    The elliptic-flow ratio of neutrons with respect to protons in reactions of neutron rich heavy-ions systems at intermediate energies has been proposed as an observable sensitive to the strength of the symmetry term in the nuclear Equation Of State (EOS) at supra-saturation densities. The recent results obtained from the existing FOPI/LAND data for $^{197}$Au+$^{197}$Au collisions at 400 MeV/nucleon in comparison with the UrQMD model allowed a first estimate of the symmetry term of the EOS but suffer from a considerable statistical uncertainty. In order to obtain an improved data set for Au+Au collisions and to extend the study to other systems, a new experiment was carried out at the GSI laboratory by the ASY-EOS collaboration in May 2011.

    The increasing number of Very High Energy (VHE) sources discovered by the current generation of Cherenkov telescopes made particularly relevant the creation of a dedicated source catalogs as well as the cross-correlation of VHE and lower energy bands data in a multi-wavelength framework. The "TeGeV Catalog" hosted at the ASI Science Data Center (ASDC) is a catalog of VHE sources detected by ground-based Cherenkov detectors. The TeGeVcat collects all the relevant information publicly available about the observed GeV/TeV sources. The catalog contains also information about public light curves while the available spectral data are included in the ASDC SED Builder tool directly accessible from the TeGeV catalog web page. In this contribution we will report a comprehensive description of the catalog and the related tools.

    The present project has been developed because of the desire to unify the research lines in the A.S.I. ‘Medicine & Biotechnology’ area into one research line that could satisfy the interests of all of the collaborative groups and at the same time could pursue a relevant social goal. A 6 month feasibility study (SF) called MoMa was carried out in the ASI framework. During the SF the know-how and the tools already available in the national scientific community have been assessed, selected and evaluated even with the important contribution of Small and Medium-size Enterprises (SME) and of Italian industries already involved in Space Research. As result of the SF MoMa, all of the participants decided to combine all the efforts together and define, with all the know-how and the available technologies, one strategic topic, the “Aging” with a special attention to the Quality of Life (QoL). The space environment is a unique laboratory to study the reaction of living organisms (especially humans) to microgravity and cosmic radiation. The study of the effects of these two variables at the molecular and cellular levels will shed light on the response of cells and living organisms to adverse stimulations that are always present even on Earth and will help us able to develop the best strategies to protect the organisms from the progressive structural and functional decline related to Aging. Relevant spin-offs on Earth and also relevant industrial applications are the expected outputs of this project.

    Full Text Available This work provides a detailed study on the growth of AlxIn1-xAsySb1-y lattice-matched to InAs by Molecular Beam Epitaxy. In order to find the conditions which lead to high crystal quality deep within the miscibility gap, AlxIn1-xAsySb1-y with x = 0.462 was grown at different growth temperatures as well as As2 and Sb2 beam equivalent pressures. The crystal quality of the grown layers was examined by high-resolution X-ray diffraction and atomic force microscopy. It was found that the incorporation of Sb into Al0.462In0.538AsySb1-y is strongly temperature-dependent and reduced growth temperatures are necessary in order to achieve significant Sb mole fractions in the grown layers. At 480 ∘ C lattice matching to InAs could not be achieved. At 410 ∘ C lattice matching was possible and high quality films of Al0.462In0.538AsySb1-y were obtained.

  13. Volumetric quantification of lung nodules in CT with iterative reconstruction (ASiR and MBIR)

    International Nuclear Information System (INIS)

    Purpose: Volume quantifications of lung nodules with multidetector computed tomography (CT) images provide useful information for monitoring nodule developments. The accuracy and precision of the volume quantification, however, can be impacted by imaging and reconstruction parameters. This study aimed to investigate the impact of iterative reconstruction algorithms on the accuracy and precision of volume quantification with dose and slice thickness as additional variables.Methods: Repeated CT images were acquired from an anthropomorphic chest phantom with synthetic nodules (9.5 and 4.8 mm) at six dose levels, and reconstructed with three reconstruction algorithms [filtered backprojection (FBP), adaptive statistical iterative reconstruction (ASiR), and model based iterative reconstruction (MBIR)] into three slice thicknesses. The nodule volumes were measured with two clinical software (A: Lung VCAR, B: iNtuition), and analyzed for accuracy and precision.Results: Precision was found to be generally comparable between FBP and iterative reconstruction with no statistically significant difference noted for different dose levels, slice thickness, and segmentation software. Accuracy was found to be more variable. For large nodules, the accuracy was significantly different between ASiR and FBP for all slice thicknesses with both software, and significantly different between MBIR and FBP for 0.625 mm slice thickness with Software A and for all slice thicknesses with Software B. For small nodules, the accuracy was more similar between FBP and iterative reconstruction, with the exception of ASIR vs FBP at 1.25 mm with Software A and MBIR vs FBP at 0.625 mm with Software A.Conclusions: The systematic difference between the accuracy of FBP and iterative reconstructions highlights the importance of extending current segmentation software to accommodate the image characteristics of iterative reconstructions. In addition, a calibration process may help reduce the dependency of

  14. Investigation of the dosimetric properties of an a-Si flat panel epid

    International Nuclear Information System (INIS)

    Full text: Electronic portal imaging devices (EPIDs) are primarily used as an electronic replacement for film to verify the set-up of radiotherapy patients based on imaged anatomy. There has recently been much interest in the use of amorphous silicon (a-Si) flat panel EPIDs for dosimetric verification in radiotherapy. The work presented here has been carried out to determine their suitability for dosimetric applications by investigating some of the basic response characteristics and the implications these might have. The measurements reported in this paper were performed using 6-MV photon beams from an Elekta Precise linear accelerator fitted with Elekta iViewGT amorphous silicon flat panel EPIDs. Measurements were performed to investigate the response of the EPID as a function of exposure and field size. Similar measurements were made with an ionisation chamber for comparison. Further measurements were carried out to investigate the response of the EPID to multiple low dose exposures (e.g. 5x2 MU) such as might be encountered in Intensity Modulated Radiotherapy (IMRT). This was compared with the response to a single high dose exposure (e.g. 10 MU) and repeated for a range of exposures. The results show the response of the EPID, to a good approximation, to be linear with dose over the range of 1 -200 MU. However, 'under-responses' in the EPID of up to 5% were seen at the lowest exposures. For multiple low dose segments the sum of the EPID responses was found to be less than the response to the same total exposure in a single large segment. This effect reduces with increase in the magnitude of the low dose segments. The variation in EPID response with field size was found to be greater than that indicated by the ionisation chamber. The results show that the a-Si detector responds to dose, to a good approximation, in a linear manner. The EPID under-response at low doses is thought to be related to the so called ghosting effect. Each image frame has a residual

    Full Text Available Este artículo examina los ajustes en la macroeconomía real de Corea y Malasia al ser golpeados por la crisis asiática, sus respectivas respuestas de política y los efectos resultantes. En ambos países los efectos negativos de la crisis fueron de magnitudes similares, en tanto sus respuestas fueron distintas. Corea buscó una asistencia directa del FMI, lo que la obligó, inicialmente, a cumplir con el programa de ajuste estructural de éste, mientras que Malasia pudo mantener políticas independientes durante el proceso de la solución de la crisis. Asimismo, Corea y Malasia adoptaron medidas totalmente opuestas en cuanto a la apertura del mercado de capitales en reacción a la crisis. Por ejemplo, Corea liberalizó drásticamente su cuenta de capitales (aunque mantuvo ciertas restricciones a la salida de capital de sus residentes, mediante un régimen cambiario de flotación (aunque con una acumulación notable de reservas internacionales vía intervención cambiaria, mientras que Malasia implementó controles de capitales más estrictos con el regreso a un régimen de tipo de cambio fijo. Pese a los diferentes enfoques de política respecto de la cuenta de capitales y al tipo de cambio, los dos países adoptaron prontamente, en 1998, un cambio sustancial hacia una política macroeconómica (fiscal y monetaria expansiva, lo que logró una recuperación de ambas economías notablemente más rápida que la de otras del Este Asiático. El papel positivo de las políticas macroeconómicas anticíclicas pos-crisis plantea la pregunta de si el endurecimiento inicial de las políticas fiscales y monetarias fue mantenido por demasiados meses y si éste, en consecuencia, profundizó la crisis tanto en Corea como en Malasia.

    2004-01-01

    A coastal vulnerability index (CVI, http://pubs.usgs.gov/of/2004/1020/html/cvi.htm) was used to map relative vulnerability of the coast to future sea-level rise within Assateague Island National Seashore (ASIS) in Maryland and Virginia. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of relative sea-level rise, shoreline change rates, mean tidal range and mean wave height. Rankings for each variable were combined and an index value calculated for 1-minute grid cells covering the park. The CVI highlights those regions where the physical effects of sea-level rise might be the greatest. This approach combines the coastal system's susceptibility to change with its natural ability to adapt to changing environmental conditions, yielding a quantitative, although relative, measure of the park's natural vulnerability to the effects of sea-level rise. The CVI provides an objective technique for evaluation and long-term planning by scientists and park managers. Assateague Island consists of stable and washover dominated portions of barrier beach backed by wetland and marsh. The areas within Assateague that are likely to be most vulnerable to sea-level rise are those with the highest occurrence of overwash and the highest rates of shoreline change.

    Core-collapse supernovae are among the most powerful explosions in the Universe, releasing about 1053 erg of energy on timescales of a few tens of seconds. These explosion events are also responsible for the production and dissemination of most of the heavy elements, making life as we know it possible. Yet exactly how they work is still unresolved. One reason for this is the sheer complexity and cost of a self-consistent, multi-physics, and multi-dimensional core-collapse supernova simulation, which is impractical, and often impossible, even on the largest supercomputers we have available today. To advance our understanding we instead must often use simplified models, teasing out the most important ingredients for successful explosions, while helping us to interpret results from higher fidelity multi-physics models. In this paper we investigate the role of instabilities in the core-collapse supernova environment. We present here simulation and visualization results produced by our code GenASiS.

    The aim of this research was to improve our understanding of how ploidy level influences phenotype and gene expression in Chinese cabbage (Brassica rapa L. ssp. pekinensis). Haploid plants (2n = 10) was induced by 0.2% colchicine to produce diploid (2n = 20) and tetraploid plants (2n = 40). The aneuploid (2n = 24) was also obtained by hybridization between diploid plants as the female and tetraploid plants. The ploidy levels of all plants were identified through chromosome counts and flow cytometry. Leaves and petals became larger as the ploidy level increased from haploid to diploid, and from aneuploid to tetraploid. Similarly, expression of ARGOS was regulated by genome size, increasing in parallel with the level of ploidy. Among the four ploidy types, expression was stronger in the floral buds than in the leaves. Expression by ASY1 also differed according to ploidy level, being highest in diploid plants, followed in order by tetraploids. Expression was similar between haploids and aneuploids at two stages-prior to and after meiosis-but was higher in the haploids during meiosis. When buds were compared within the same ploidy type at different stages, ASY1 expression was obviously higher during meiosis than either before or after. Our study demonstrated the generation and phenotype of a ploidy Chinese cabbage series derived from one haploid. Expression of genes ARGOS and ASY1 were modulated by genome size in this ploidy series, and the regulated patterns of the two genes was different. PMID:27162487

EPIDs were originally developed to provide on-treatment radiological imaging to assist with patient setup, but there has also been a natural interest in using them as dosimeters since they use the megavoltage therapy beam to form images. The current generation of clinically available EPID technology, amorphous-silicon (a-Si) flat panel imagers, possess many characteristics that make them much better suited to dosimetric applications than earlier EPID technologies. Features such as linearity with dose/dose rate, high spatial resolution, realtime capability, minimal optical glare, and digital operation combine with the convenience of a compact, retractable detector system directly mounted on the linear accelerator to provide a system that is well-suited to dosimetric applications. This review will discuss clinically available a-Si EPID systems, highlighting dosimetric characteristics and remaining limitations. Methods for using EPIDs in dosimetry applications will be discussed. Dosimetric applications using a-Si EPIDs to estimate three-dimensional dose in the patient during treatment will be overviewed. Clinics throughout the world are implementing increasingly complex treatments such as dynamic intensity modulated radiation therapy and volumetric modulated arc therapy, as well as specialized treatment techniques using large doses per fraction and short treatment courses (ie. hypofractionation and stereotactic radiosurgery). These factors drive the continued strong interest in using EPIDs as dosimeters for patient treatment verification.

    Full Text Available Article in German, Abstracts in English and SpanishAmerica in Asia: Alexander von Humboldt's «Asie centrale» in the context of TransArea StudiesSince 1793, Alexander von Humboldt had been dreaming of realizing a travel to Russia, leading him right into Central Asia. In 1829, he finally was able to see his dream fulfilled, although the contexts and conditions of his travel to Russia were totally different from those of his voyage to the Americas, realized some thirty years earlier. Severely controlled by the Russian monarchy, the travellers made it up to the Chinese border, rapidly crossing, within very few months and with the help of more than 12000 horses, more than 18000 kilometers.This article analizes the outstanding importance of Humboldt's Asian project in the context of Humboldtian Science, specially focussing the relevance of TransArea studies within its omnipresent AsiAmerican dimensions. Therefore, Asie centrale occupies a highly specific place within the complex cosmos of Humboldt's writings, highlighting a fascinating transdisciplinary and geoecological approach still of great importance today.

  5. The control of the film stress of Cat-CVD a-Si films and its impact on explosive crystallization induced by flash lamp annealing

    International Nuclear Information System (INIS)

    Catalytic chemical vapor deposition (Cat-CVD) can produce amorphous silicon (a-Si) films with low film stress, in general, compared to plasma-enhanced CVD, and is thus suited for the preparation of precursor a-Si films for thick poly-Si films applied for solar cells. The stress of a-Si films is known to sometimes play an important role for the crystallization of a-Si films and resulting grain size of polycrystalline Si (poly-Si) films formed. I investigate the impact of the stress of Cat-CVD a-Si films on the mechanism of explosive crystallization (EC) induced by flash lamp annealing (FLA). The stress of Cat-CVD a-Si films can be controlled by changing the temperatures of substrates and/or a catalyzing wire during film deposition. Cat-CVD a-Si films with tensile stress (~ 200 MPa) can be deposited as well as films with compressive stress. The enlargement of grain size is observed in a part of flash-lamp-crystallized (FLC) poly-Si films formed from Cat-CVD films with tensile stress compared to those with compressive stress, which might be an indication of a certain degree of impact of film stress on poly-Si formation. The grain size is, however, much smaller than that of FLC poly-Si films formed from electron-beam- (EB-) evaporated a-Si films with similar tensile stress. This fact may indicate the existence of other critical determinants of EC mechanism

  8. Image quality of iterative reconstruction in cranial CT imaging: comparison of model-based iterative reconstruction (MBIR) and adaptive statistical iterative reconstruction (ASiR)

    International Nuclear Information System (INIS)

    The purpose of this study was to compare cranial CT (CCT) image quality (IQ) of the MBIR algorithm with standard iterative reconstruction (ASiR). In this institutional review board (IRB)-approved study, raw data sets of 100 unenhanced CCT examinations (120 kV, 50-260 mAs, 20 mm collimation, 0.984 pitch) were reconstructed with both ASiR and MBIR. Signal-to-noise (SNR) and contrast-to-noise (CNR) were calculated from attenuation values measured in caudate nucleus, frontal white matter, anterior ventricle horn, fourth ventricle, and pons. Two radiologists, who were blinded to the reconstruction algorithms, evaluated anonymized multiplanar reformations of 2.5 mm with respect to depiction of different parenchymal structures and impact of artefacts on IQ with a five-point scale (0: unacceptable, 1: less than average, 2: average, 3: above average, 4: excellent). MBIR decreased artefacts more effectively than ASiR (p < 0.01). The median depiction score for MBIR was 3, whereas the median value for ASiR was 2 (p < 0.01). SNR and CNR were significantly higher in MBIR than ASiR (p < 0.01). MBIR showed significant improvement of IQ parameters compared to ASiR. As CCT is an examination that is frequently required, the use of MBIR may allow for substantial reduction of radiation exposure caused by medical diagnostics. (orig.)

  10. Managing the backscatter component from the robotic arm of an a-Si EPID

    International Nuclear Information System (INIS)

    Full text: Backscatter from the robotic arm mechanism of an a-Si EPID in IMRT images was examined. Images corrected with a conventional flood field (FF) containing a backscatter component (BSC) from the robotic ann were compared with a BSC-free FF. A Yarian 21 EX linac (6 MV, 18 MV) was used. All images were acquired with two aS500 EPIDs, one R-arm and one E-arm. The BSC of an EPID image is the ratio of an image acquired with the EPID attached to the arm then detaching the arm from the EPID and acquiring the same image. A range of square field sizes from 2.5 x 2.5 cm to 27.5 x 27.5 cm were acquired and the BSC analyzed. The BSC of the FFs were also measured. A series of IMRT fields were acquired. Each field was corrected with a conventional FF and compared with a BSC-free FF. Figure I shows the magnitude of the BSC from each arm in the inplane for a 6x beam. Square fields above 16 x l6 cm (R-arm) and lO x 10 cm (E-arm) benefited from a conventional FF as it tended to cancel out the BSC in the acquired square field. The opposite was observed for smaller field sizes. A gamma analysis of the IMRT fields showed a FF correction containing a BSC reduces the effect of the arm in the final image. IMRT EPID images using conventional FFs have been shown to be less affected by backscatter from the robotic arm compared to BSC-free flood fields. (author)

  11. A novel method to achieve selective emitter for silicon solar cell using low cost pattern-able a-Si thin films as the semi-transparent phosphorus diffusion barrier

    International Nuclear Information System (INIS)

    Highlights: ► a-Si thin films as semitransparent phosphorus diffusion barriers for solar cell. ► a-Si thin films on silicon wafers were patterned by the alkaline solution. ► Selective emitter was formed with patterned a-Si as diffusion barrier for solar cell. -- Abstract: Selective emitter for silicon solar cell was realized by employing a-Si thin films as the semi-transparent diffusion barrier. The a-Si thin films with various thicknesses (∼10–40 nm) were deposited by the electron-beam evaporation technique. Emitters with sheet resistances from 37 to 145 Ω/□ were obtained via POCl3 diffusion process. The thickness of the a-Si diffusion barrier was optimized to be 15 nm for selective emitter in our work. Homemade mask which can dissolve in ethanol was screen-printed on a-Si film to make pattern. The a-Si film was then patterned in KOH solution to form finger-like design. Selective emitter was obtainable with one-step diffusion with patterned a-Si film on. Combinations of sheet resistances for the high-/low-level doped regions of 39.8/112.1, 36.2/88.8, 35.4/73.9 were obtained. These combinations are suitable for screen-printed solar cells. This preparation method of selective emitter based on a-Si diffusion barrier is a promising approach for low cost industrial manufacturing.

    Objective: This study compared the performance of the immunochromatographic strip (ICS) to the Venereal Disease Research Laboratory (VDRL) test and Treponema pallidum haemagglutination assay (TPHA) at a primary health care setting. Methods: The study group was comprised of 150 females randomly drawn from a population of pregnant women attending their first antenatal visit or follow-up visits at West Maternity Hospital in Eldoret Kenya, but without a previous syphilis test during that pregnancy. On-site VDRL, ICS and TPHA tests were performed and immediate treatment provided where appropriate. The performance of the three tests was compared. Results: The sero-prevalence of syphilis as determined by the VDRL test was 3%. There was no significant difference between the ICS and the VDRL test (P > 0.05). The sensitivity and specificity of the ICS test were 80% and 98.6% respectively, while the negative predictive value (NPV) and positive predictive value (PPV) were both 100%. On the other hand, the sensitivity and specificity of the VDRL test were 66.7% and 99.3%, while the NPV and PPV were 80% and 98.6% respectively. The Treponema pallidum haemagglutination assay was used as a reference test and had sensitivity, specificity, NPV and PPV of 100%. Conclusion: The diagnostic accuracy of the ICS compared favorably with theVDRL gold standard. The use of the ICS in Kenya can improve the diagnosis of syphilis in health facilities both with and without laboratories and allow community health care workers to make a rapid diagnosis of the disease, and consequently make immediate therapeutic decisions.

The ASI is a frequently used clinical and research instrument that measures severities in seven functional domains in people with substance abuse disorders. Methods: A total of 370 male inpatients with a history of alcohol dependence participated in the study. Forty-nine participants were excluded in the final analysis due to lack of reliability (i.e., patient misrepresentation or inability to understand. We used the ASI-J and a series of indexes that determined patient states during and post-treatment. Results: The correlations between ASI Composite Scores (CSs, which were calculated through a weighted formula and indicated the severity of each problem area, were significant but low in eight relations and not significant in 13 relations, indicating substantial independence of the problem areas. Significant differences were found in Family/Social CSs between abstinent and relapsed alcohol-dependent individuals. The questions of undesirable attitude were significantly related to the CSs of Employment, Drug use, Family/Social, and Psychiatric sections. Significant differences were observed in patient demographics, CS, and ASI Severity Rating (SR and interviewer’s subjective scoring between alcohol-dependent individuals and drug abusers. CSs in Japanese alcohol-dependent individuals were generally similar to corresponding CSs in individuals from other countries, with the exception of The Netherlands. Conclusions: This study demonstrated that the ASI-J is useful for understanding individual profiles of problems for each patient and planning customized treatment. The ASI-J served as a predictive tool for relapse and compliance to treatment afterward and was shown to be useful as a comparison tool in clarifying similarities and differences between substance abuser groups.

    2003-01-01

    Using molecular-dynamics computer simulation, we study the processes occurring in a-Si after irradiation with a projectile with energy E sub 0<=500 eV. By comparing Au and Si impact, we can study the effects of high and low deposited energy density. We find that damage production (creation of over- and under-coordinated Si atoms) and recoil implantation are strongly enhanced under Au impact. This effect can be traced back to the creation of an elastic collision spike for Au impact.

    The fabrication of ultra-thin SiN{sub x} (< 2 nm) is a necessary step in third generation photovoltaics, memory, or light-emitting diode applications. Using the low temperature, cheap, scaleable synthesis technique of hot-wire chemical vapor deposition (HWCVD) for this purpose poses many challenges. Here, an approach of fabricating ultra thin SiN{sub x} of thickness ∼ 1.9 nm in a superlattice (SL) structure via nitridation of a-Si layers in-situ HWCVD at 250 °C is reported. Quantum well SL and quantum dot (QD) SL films are realized, wherein SiN{sub x} layers are formed by nitriding a-Si. Both these films investigated by Raman spectroscopy and high resolution transmission electron microscopy, reveal the formation of ultra-thin SiN{sub x} in a SL structure with a-Si, accompanied by sharp interfaces. In addition, annealing of the SL structures, results in QDs of crystalline Si in the a-Si layers, maintaining the SiN{sub x} layer as well as the sharp interface between the SiN{sub x} and a-Si layers of the as-deposited SL structure. - Highlights: • Ultra thin SiN{sub x} is fabricated by hot wire chemical vapor deposition. • SiN{sub x} layer of thickness ∼ 1.9 nm is formed via nitridation of a-Si layer at 250 °C. • Ultra thin SiN{sub x} layers are realized in superlattice films of quantum wells and quantum dots.

    2002-01-01

    We have been investigating the potential of large area active matrix flat-panel a-Si : H imaging arrays for full-field digital X-ray mammography. To optimise the overall performance of such an imaging system under mammographic conditions, four different Gd sub 2 O sub 2 S : Tb phosphor screens (i.e. Lanex Fast-Back, Regular, Fine and MinR-2000) were employed and our full-field detector was integrated with the Feinfocus DIMA (Direct Magnification) PLUS MII mammographic unit. The spatial resolution and the image noise of the digital detector were measured and the X-ray imaging performance of the whole system was also evaluated with two mammographic phantoms. It was deduced from the results of this study that Regular screen offers the best compromise between sensitivity and spatial resolution and exhibits better overall image-quality performance than that of a conventional mammography system.

    Four years׳ behavioral data of thin-film single junction amorphous silicon (a-Si) photovoltaic (PV) modules installed in a relatively dry and sunny inland site with a Continental-Mediterranean climate (in the city of Jaén, Spain) are presented in this article. The shared data contributes to clarify how the Light Induced Degradation (LID) impacts the output power generated by the PV array, especially in the first days of exposure under outdoor conditions. Furthermore, a valuable methodology is provided in this data article permitting the assessment of the degradation rate and the stabilization period of the PV modules. Further discussions and interpretations concerning the data shared in this article can be found in the research paper "Characterization of degradation and evaluation of model parameters of amorphous silicon photovoltaic modules under outdoor long term exposure" (Kichou et al., 2016) [1].

    Full Text Available Objective: The aim of this study is to test ambivalent sexism inventory (ASI and ambivalence towards men inventory (AMI, which were developed on the basis of the Ambivalent Sexism approach. Method: The sampling was formed by 422 students (252 women and 169 men from University of Cumhuriyet. The data of the study were obtained from the questionnaire determining their socio-demographic characteristics of the students and AMI and ASI in order to determine their tendencies of sexism. After obtaining the permission from the Rectorate of Cumhuriyet University, the application was carried out with the help of academic staff at relevant faculties and vocational schools between 01.02.2012 and 30.04.2012. Results: When the overall average of the scores obtained from ASI and AMI were considered, it was found out that the ambivalence of the participants against each other (with ASI x=4,12; AMI x=4,22 was above the average; and men (with x= 4,23 had more ambivalence compared to women (x=4,05 in ASI, and women (x=4,38 had more ambivalence compared to men (x=3,99 in AMI. The data obtained from the variance analysis suggested that there were significant differences among the participants by gender, which were Hostile sexism (HS for men (t(421=-7,99 p<0,05, Benevolent sexism (BS for women (t(421=4,28 p<0,05 in ASI; and Hostility attitudes towards men (HM for women (t(421=-15,33 p<0,05, Benevolence towards men (BMfor men (t(421= -5,18 p<0,05. In other words, male participants had more hostile attitudes towards women in ASI and female participants had more hostile attitudes towards men in AMI. When the correlations among the sub-factors of AMI and ASI are considered, the correlations between HM and BS (0.47, BM and HS (0.47, and BM and BS (0.40 are statistically important. These findings suggest that the benevolent attitudes towards men are in a positive relationship with both benevolent and hostile sexism against women. Conclusions: The obtained data suggest that

    A multifunctional solar facade consisting of transparent glazing and amorphous silicon photovoltaic panels has been tested at Helsinki University of Technology, Finland (60 deg. N). The facade has a central window and PV panels below and beside the window, with gaps of clear glazing between the PV panels beside the window. The daylight illuminance inside a test room behind the facade was measured at three horizontal points on the interior desk level. Assuming a lighting requirement of 500 lx and continuous electric light dimming, the average daylight availability DA was about 55% during the office hours (9 am to 5 pm) for the test room during the measurement period from October to March. The DA for the summer months was almost 100%. However, no blinds were used at the test facade. For that reason, the DA was also calculated for a typical office room at four European locations with an optimized facade layout which has, as an addition to the test facade, Venetian blinds in the central section of the facade, and PV panels above the central clear-glazing window with gaps of diffusive glazing between these PV panels, so that no blinds are necessary at the top section of the facade. The yearly average DA for the optimized facade ranged from 60% in Sodankylae, Finland (67 deg. N) to almost 90% in Trapani, Sicily (38 deg. N). A continuous daylight-responsive electric light dimming and blind control system was used for the calculations. (au)

    Multivariate optical computing (MOC), an optical sensing technique for analog calculation, allows direct and robust measurement of chemical and physical properties of complex fluid samples in high-pressure/high-temperature (HP/HT) downhole environments. The core of this MOC technology is the integrated computational element (ICE), an optical element with a wavelength-dependent transmission spectrum designed to allow the detector to respond sensitively and specifically to the analytes of interest. A key differentiator of this technology is it uses all of the information present in the broadband optical spectrum to determine the proportion of the analyte present in a complex fluid mixture. The detection methodology is photometric in nature; therefore, this technology does not require a spectrometer to measure and record a spectrum or a computer to perform calculations on the recorded optical spectrum. The integrated computational element is a thin-film optical element with a specific optical response function designed for each analyte. The optical response function is achieved by fabricating alternating layers of high-index (a-Si) and low-index (SiO2) thin films onto a transparent substrate (BK7 glass) using traditional thin-film manufacturing processes (e.g., ion-assisted e-beam vacuum deposition). A proprietary software and process are used to control the thickness and material properties, including the optical constants of the materials during deposition to achieve the desired optical response function. The ion-assisted deposition is useful for controlling the densification of the film, stoichiometry, and material optical constants as well as to achieve high deposition growth rates and moisture-stable films. However, the ion-source can induce undesirable absorption in the film; and subsequently, modify the optical constants of the material during the ramp-up and stabilization period of the e-gun and ion-source, respectively. This paper characterizes the unwanted

    Pursuant to the measuring of temperature dependency of the characteristics such as conversion efficiency, during the process of degradation in a-Si solar cells due to light and electric current and the process of recovery by annealing, this paper describes changes in temperature coefficients, correlation between the characteristic parameters and the degradation, and the results of the examination of their characteristics. The conversion efficiency {mu} degraded approximately by 45% of the initial value each by the irradiation under a light intensity with 3 SUN accelerated and by the infusion of current at 20mA/cm{sup 2}; and then, the efficiency recovered to 70-75% of the degradation by subsequent annealing. In addition, in the temperature dependency at 80{degree}C against at 20{degree}C, Isc slightly increased while Vcc greatly decreased. This slight increase in Isc was mainly due to the decrease in the width of the forbidden band, while the decrease in Vcc was due to the increase in the reverse saturation current. The temperature dependency of {mu}N was negative, becoming small in accordance with the degradation. The temperature dependency of FF/FFO was negative initially both in light and current, but it decreased with the degradation and turned to positive. The temperature coefficients of I-V parameters reversibly changed corresponding to the degradation and recovery of these parameters and stayed in a good correlation. 7 refs., 8 figs., 1 tab.

    1985-01-01

    In July of 1984, Hughes and JPL initiated a contract for Hughes to design, fabricate and test 10 thin film Amorphous Silicon (a-Si) photovoltaic power modules. These modules were to be 1 ft x 4 ft in size. They were to be preceded by the delivery of 10 a-Si 4 in. square test devices. This effort is very timely since thin film PV development has progressed to the point where intermediate load power applications are on the horizon. It is important to know if current a-Si submodule design and manufacturing processes yield a product that is compatible with the packaging needed to meet a 20 to 30 year life span expectancy. The term submodule is assigned to an interconnected assembly of 28 a-Si cells deposited on a 1 foot square glass superstrate. These assemblies are equipped with electrical terminations, i.e., copper tabs at the four corners of the inverted submodules. It is these submodules that are to be interconnected and packaged into power modules, as opposed to the interconnected individual crystalline cells packaged into todays PV modules. A discussion of the fabrication methods and results follows.

    The properties of a tetrahedron containing Bi2AO5 (A=Si, Ge) are examined using Ab initio calculations and symmetry mode analysis. Stabilization of the polar phase is observed in both compounds with a monoclinic Cc phase. In the monoclinic ground state, the tilting angle (ϕ1) of tetrahedron is 7.21° and 21.94° for the Si and Ge compound, respectively. The relationship between a primary order parameter and the tetrahedral tilting is identified and an analytical formula between them is proposed by analyzing the structure. The detailed layer-by-layer polarization calculations shows that the main polarization component originates from the tetrahedron tilting of the AO4 unit, and the analytical relationship between the primary order parameter and spontaneous polarization is also calculated. This B3LYP hybrid functional calculation provides a band gap of 4.44 eV and 4.18 eV for Bi2SiO5 and Bi2GeO5, respectively. The main difference between the two compounds is also analyzed based on the electronic structure and electron localization function analysis.

  20. Improvement of Varian a-Si EPID dosimetry measurements using a lead-shielded support-arm

    International Nuclear Information System (INIS)

    Dosimetry measurements with Varian amorphous silicon electronic portal imaging devices (a-Si EPIDs) are affected by the backscattered radiation from the EPID support arm. In this study, the nonuniform backscatter from an E-type support arm was reduced by fixing a thick (12.2 × 10.5 × 0.5 cm3) piece of lead on top of the arm, and the remaining backscatter was modeled and included in an existing dose prediction algorithm. The applied backscatter kernel was the average of kernels on different regions of the EPID over the arm. The lead-shielded arm reduced the nonuniform backscatter component by about 50% for field sizes ranging from 3 × 3 to 30 × 30 cm2 and the field symmetry improved for medium to large fields up to 3%. Gamma evaluation of the measured and modeled doses (2%, 2-mm criteria) showed that using the lead-shielded arm in the model increased the number of points with Gamma index <1 by 5.7% and decreased the mean Gamma by 0.201. Even using the lead alone (no modeling) could increase the number of points with Gamma index <1 by 4.7% and decrease the mean Gamma by 0.153. This is a simple and easy method to decrease the nonuniform arm backscatter and improve the accuracy of dosimetry measurements with the existing EPIDs used for clinical applications.

The detection system consisted of the Large Area Neutron Detector LAND, combined with parts of the CHIMERA multidetector, of the ALADIN Time-of-flight Wall, and of the Washington-University Microball detector. The latter three arrays were used for the event characterization and reaction-plane reconstruction. In addition, an array of triple telescopes, KRATTA, was used for complementary measurements of the isotopic composition and flows of light charged particles. From the comparison of the elliptic flow ratio of neutrons with respect to charged particles with UrQMD predictions, a value \\gamma = 0.72 \\pm 0.19 is obtained for the power-law coefficient describing the density dependence of the potential part in the parametrization of the symmetry energy.

    Amorphous silicon nanowires 'a-SiNWs' have been prepared by electrospinning a liquid silane-based precursor. Cyclohexasilane 'Si6H12' was admixed with poly-methyl methacrylate (PMMA) in toluene giving an ink that was electrospun into the Si6H12/PPMA wires with diameters of 50-2000 nm. Raman spectroscopy revealed that thermal treatment at 350 C transforms this deposit into a-SiNWs. These materials were coated with a thin carbon layer and then tested as half-cells where a reasonable plateau in electrochemical cycling was observed after an initial capacity fade. Additionally, porous a-SiNWs were realized when the thermally decomposable binder polypropylene carbonate/polycyclohexene carbonate was used as the polymer carrier.

  6. ASI: Dunaliella marine microalgae to drop-in replacement liquid transportation fuel

    KAUST Repository

    Wang, Weicheng

    2013-09-11

    Microalgae are a promising biofuels feedstock, theoretically yielding concentrations of triacylglycerides (TAGs) per unit area that are far higher than traditional feedstocks due to their rapid growth. Dunaliella is particularly advantageous as a feedstock because it is currently commercially mass cultured, thrives in salt water, and has no cell wall. Fourteen strains of Dunaliella have been investigated for growth rates and lipid production in mass culture and tested for enhanced lipid production under a range of environmental stressors including salinity, pH, nitrogen and phosphorus limitation, and light regime. The nuclear genome has been sequenced for four of these strains, with the objective of increasing carbon flux through genetic engineering. Electroflocculation followed by osmotic membrane rupturing may be a very energy and cost efficient means of harvesting the lipid bodies from Dunaliella. A technically feasible and scalable thermo-catalytic process to convert the lipids into replacements for liquid transportation fuels has been developed. The lipids were converted into long-chain alkanes through continuous thermal hydrolysis followed by fed-batch thermo-catalytic decarboxylation. These alkanes can be reformed into renewable diesel via conventional catalytic hydrocarbon isomerization reactions to improve cold flow properties, if desired. © 2013 American Institute of Chemical Engineers Environ Prog, 32: 916-925, 2013 Copyright © 2013 American Institute of Chemical Engineers Environ Prog.

[Methods] Using RACE method, we cloned the asy cDNA from Phaffia rhodozyma 7B12, and constructed recombinant plasmid pET32-asy. After optimizing the temperature and IPTG concentration, the soluble expression of Asy was achieved in E. coli BL21(DE3). pET32-asy and pACCAR16Acrtx which carried the genes chain on the synthesis of beta-carotene by acetyl CoA were co-transformed into E. coli BL21(DE3), and the changes of carotenoid species were analyzed by HPLC to detect the activity of Asy. [Results] The homology between new cloned cDNA sequence of asy gene (accession No. HM204708.1) and the only reported asy mRNA sequence (accession No. DQ002007.1) was 97%. The obtained cDNA was 1 971 bp in length, the longest open reading frame was 1 614 bp encoding 538 amino acids, and therefore the fusion protein expressed in E. coli BL21(DE3) was about 70 kD. At the optimizing condition (induced by 0.5 mmol/L IPTG, at 26 癈, 5 h), 85% fusion protein expressed by recombinant pET32-asy was soluble. Compared the components of pigment in the E. coli strain only transformed with pAC-CAR16Acrtx with the strain co-transformed with pACCAR16Acrtx and pET32-asy, we found some changes of carotenoid components. The peak presented a-carotene was disappeared and three new peaks were shown, suggested that p-cryptoxanthin which is one of themetabolic intermediates between P-carotene and astaxanthin were produced because of Asy expression. [Conclusion] Astaxanthin synthase cDNA was cloned from Phaffia rhodozyma 7B12 and the soluble expression of astaxanthin synthase in E. coli BL21(DE3) was obtained. The fusion protein had a certain activity to transform p-carotene.%[目的]从高

  14. Parameter variation of the one-diode model of a-Si and a- Si/μc-Si solar cells for modeling light-induced degradation

    International Nuclear Information System (INIS)

    For analyzing the long-term behavior of thin film a-Si/μc-Si photovoltaic modules, it is important to observe the light-induced degradation (LID) in dependence of the temperature for the parameters of the one-diode model for solar cells. According to the IEC 61646 standard, the impact of LID on module parameters of these thin film cells is determined at a constant temperature of 50°C with an irradiation of 1000 W/m2 at open circuit conditions. Previous papers examined the LID of thin film a-Si cells with different temperatures and some others are about a-Si/μc-Si. In these previous papers not all parameters of the one-diode model are examined. We observed the serial resistance (Rs), parallel resistance (Rp), short circuit current (Isc), open circuit voltage (Uoc), the maximum power point (MPP: Umpp, Impp and Pmpp) and the diode factor (n). Since the main reason for the LID of silicon-based thin films is the Staebler Wronski effect in the a-Si part of the cell, the temperature dependence of the healing of defects for all parameters of the one-diode model is also taken into account. We are also measuring modules with different kind of transparent conductive oxides: In a-Si thin film solar cells fluorine-doped tin oxide (FTO) is used and for thin film solar cells of a-Si/μc-Si boron- doped zinc oxide is used. In our work we describe an approach for transferring the parameters of a one-diode model for tandem thin film solar cells into the one-diode model for each part of the solar cell. The measurement of degradation and regeneration at higher temperatures is the necessary base for optimization of the different silicon-based thin films in warm hot climate

  15. Physical and tribological properties of a-Si1-xCx:H coatings prepared by r.f. plama-assisted chemical vapour deposition

    International Nuclear Information System (INIS)

    A-Si1-xCx:H films deposited by r.f. plasma-assisted chemical vapour deposition were studied as a function of their composition. The friction and wear properties were investigated with the help of a conventional ball-on-disc apparatus. These results are correlated with chemical (Si/C atomic ratio) and structural (Raman and infrared spectroscopy) properties. The friction coefficient in a humid ambient atmosphere changes markedly with the carbon fraction and reaches a value as low as 0.05 for coatings with 70 to 90 at.% C. The carbon-rich films consist of diamond-like carbon with silicon. (orig.)

    2015-06-15

    Purpose: To develop ultra-low dose computed tomography (CT) attenuation correction (CTAC) acquisition protocols for pediatric positron emission tomography CT (PET CT). Methods: A GE Discovery 690 PET CT hybrid scanner was used to investigate the change to quantitative PET and CT measurements when operated at ultra-low doses (10–35 mAs). CT quantitation: noise, low-contrast resolution, and CT numbers for eleven tissue substitutes were analyzed in-phantom. CT quantitation was analyzed to a reduction of 90% CTDIvol (0.39/3.64; mGy) radiation dose from baseline. To minimize noise infiltration, 100% adaptive statistical iterative reconstruction (ASiR) was used for CT reconstruction. PET images were reconstructed with the lower-dose CTAC iterations and analyzed for: maximum body weight standardized uptake value (SUVbw) of various diameter targets (range 8–37 mm), background uniformity, and spatial resolution. Radiation organ dose, as derived from patient exam size specific dose estimate (SSDE), was converted to effective dose using the standard ICRP report 103 method. Effective dose and CTAC noise magnitude were compared for 140 patient examinations (76 post-ASiR implementation) to determine relative patient population dose reduction and noise control. Results: CT numbers were constant to within 10% from the non-dose reduced CTAC image down to 90% dose reduction. No change in SUVbw, background percent uniformity, or spatial resolution for PET images reconstructed with CTAC protocols reconstructed with ASiR and down to 90% dose reduction. Patient population effective dose analysis demonstrated relative CTAC dose reductions between 62%–86% (3.2/8.3−0.9/6.2; mSv). Noise magnitude in dose-reduced patient images increased but was not statistically different from pre dose-reduced patient images. Conclusion: Using ASiR allowed for aggressive reduction in CTAC dose with no change in PET reconstructed images while maintaining sufficient image quality for co

    Full Text Available César Vallejo y Pablo Neruda fuman el opio cuando están escribiendo Trilce (1922 y Residencia en la tierra (1935, respectivamente. No mencionan la droga en sus colecciones, pero ambos escriben al margen de su obra literaria textos sobre su experiencia narcótica: un cuento-testimonio, en Vallejo; confesiones y memorias, en Neruda. Los dos poetas igualmente describen al opio como una puerta de valoración de lo asiático, sus costumbres y habitantes. Por medio del análisis de los escritos sobre el opio de Vallejo en su cuento "Cera" de Escalas melografiadas (1923 y de Neruda en su poema "El opio en el Este" de Memorial de Isla negra (1964, este artículo investiga, por un lado, los conceptos estéticos que se revelan en las relaciones del opio con la escritura de estos poetas, y por otro lado, las relaciones del opio con lo asiático que establecen los escritores como una forma de definir sus concepciones políticas.

  1. Determination of hydrogen concentration in a-Si and a-Ge layers by elastic recoil detection analysis

    International Nuclear Information System (INIS)

    Compete text of publication follows. Hydrogenated amorphous Si and Ge films are of current interest in academic and industrial research due to their unique physical properties and important applications. The incorporation of hydrogen in the amorphous network is an accepted means for reducing the density of defect states in the midgap. The passivation of dangling-bonds leads to a significant improvement in the electronic and optical properties of these layers. However, hydrogen is also suspected to degrade the performance of amorphous Si and Ge material and devices. Several studies related to hydrogen motion have been proposed to explain the light and thermal degradation effect in these layers. Thus to improve the performance and reliability of these devices, it is crucially important to understand the role of hydrogen in amorphous layers. In our previous works the structural changes of hydrogenated a-Si/Ge multilayers as a function of annealing condition was investigated. It was shown that during annealing the samples underwent significant structural changes. Due to the fast out-diffusion of hydrogen from the layers prepared with high (6 ml/min) H2 flow rate, bubbles and craters were created on the surface. However, in the multilayer samples prepared with hydrogen flow rate lower than 6 ml/min the macroscopic degradation by formation bubbles and craters was more moderated. The diffusion measurement shows that in these samples the structural degradation and intermixing of layers was slower than in the non-hydrogenated samples. As it was suggested the hydrogen can inactivate the dangling bonds of amorphous layers and, as a result of this, the intermixing slows down. It was also predicted that the hydrogen first released from the Ge layers because of the lower binding energy. In this work, we have studied the individual a-Si and a-Ge hydrogenated layers prepared by RF sputtering on Si (100) substrates. The absolute value of atomic content of the H was determined by

A comparative study of structural and optical properties has been performed and its applications in environmental field. The a-Si1−xCx:H films were investigated by scanning electron microscopy (SEM), UV–visible-NIR spectrophotometry, infrared absorption spectroscopy, secondary ion mass spectrometry (SIMS), and photoluminescence. The measured optical gap of a-Si1−xCx:H thin films depend on the carbon concentration with x varying from 0.18 to 0.30. This can be probably explained by the changes of Sp3 (silicon or film with low carbon content) to sp2 (high carbon content) configuration. Finally, different devices structures based the thin films have been investigated as gas sensors as Pd/a-Si0.72C0.28:H with a good sensitivity of CO2 and H2 gases at low bias voltage ranging from 0.05 to 0.26 volt, respectively and a low response time of 29 s and 25 s was obtained at 165 ppm of the used gases, with a recovery time of 32 s and 23 s for CO2 and H2 gases, respectively

  5. Influence of baking on the photoluminescence spectra of In1-x Gax Asy P1-y solid solutions grown on Inp substrates

    International Nuclear Information System (INIS)

    The influence of thermal treatments on the photoluminescence spectra of In1-x Gax Asy P1-y epitaxial layers of various compositions grown by LPE on In P substrates has been studied. To prevent the epitaxial layers from degradation, due to phosphor evaporation during the baking, their surface was covered by spin-on SiO2 layers. The photoluminescence spectra did not change for solid solutions whose compositions were near In P and InGaAs. For compositions in the middle of the lattice-matched region, the variations were very noticeable because the appearance of additional peaks in the luminescence spectra. This could be related to the decomposition of those solid solutions whose compositions lie inside a theoretically predicted miscibility gap. (Author)

    International Nuclear Information System (INIS)

    Within an interpolation scheme, we have determined the electron g-factor and the Kane interband energetic parameter of Ga1−xInxAsySb1−y–GaSb semiconductors quaternary alloy and used them to determine the electron g-factor in GaSb–Ga1−xInxAsySb1−y–GaSb spherical quantum dots (SQDs) as well as to calculate the Landau levels. In the low-dimensional systems a framework of an eight-band effective-mass model in which the contribution of the conduction remote bands and the k-vector · p-vector mixing between the conduction band Γc6 and the valence bands Γv8 and Γv7 states are considered. Our results show that the dependence of the bulk electron g-factor as a function of x can be fit with a cubic polynomial. We have established a relation between the electron g-factor and both the radius and the indium concentration in GaSb–Ga1−xInxAsySb1−y–GaSb SQDs. For these quaternary SQDs with a parabolic confining potential we have found that the difference between the electron energy levels corresponding to spin-up and spin-down states is larger (∼ 10 meV) than the corresponding states in GaAs–(Ga, Al)As quantum wells (QWs) (∼ 0.2 meV) of comparable dimensions and increases with the applied magnetic field

  10. Long-term experimental testing of a-silicon modules

    International Nuclear Information System (INIS)

    Long-term stability of photovoltaic module electrical performance is critically important to the economic viability of PV in large-scale energy-generation applications. Equally important is having the means to conclusively demonstrate long life to potential users; this requires proven test methods that accurately predict field performance trends. To assess the long-term stability of a-Si modules and the usefulness of existing crystalline-Si test methods a number of first generation a-Si photovoltaic modules have been acquired from leading manufacturers and subjected to a variety of accelerated and real-time outdoor aging tests. Data to date indicate that the degradation of a-Si modules involves complex dependencies that negate some of the key test correlations previously established for crystalline-Si modules. Key research priorities are highlighted including light induced effects, cell corrosion leading to increased series resistance, glass breaking strength for large modules, and the development of protective encapsulants that meet the outdoor weathering and voltage isolation required for long module life

    Modern electronic devices are unthinkable without the well-controlled formation of interfaces at heterostructures. These often involve at least one amorphous material. Modeling such interfaces poses a significant challenge, since a meaningful result can only be expected by using huge models or by drawing from many statistically independent samples. Here we report on the results of high throughput calculations for interfaces between crystalline silicon (c-Si) and amorphous silicon nitride (a-Si$_3$N$_{3.5}$:H), which are omnipresent in commercially available solar cells. The findings reconcile only partly understood key features. At the interface, threefold coordinated Si atoms are present. These are caused by the structural mismatch between the amorphous and crystalline part. The local Fermi level of undoped c-Si lies well below that of a-SiN:H. To align the Fermi levels in the device, charge is transferred from the a-SiN:H part to the c-Si part resulting in an abundance of positively charged, threefold coord...

  15. Lattice vibrations study of Ga1-xInxAsySb1-y quaternary alloys with low (In, As) content grown by liquid phase epitaxy

    International Nuclear Information System (INIS)

    Raman scattering spectroscopy was used to measure and analyze the lattice vibrations in some quaternary Ga1-xInxAsySb1-y alloys with low (In, As) contents (0.03 0C. High Resolution X-Ray Diffraction results showed profiles associated with a quaternary layer lattice matched to the GaSb substrate as obtained from the (004) reflection. The experimental diffractograms were simulated to estimate alloy composition, thickness and lattice mismatch of the layer. Raman scattering results show phonon frequencies associated to the TO and LO GaAs-like modes as well as GaSb + InAs-like mode, which are characteristic of this quaternary alloy. The As content dependence of the phonon frequency measured in this alloy for low (In, As) contents agree well with the modified Random-Element Isodisplacement (REI) model and also with other available experimental reports. This method can also be used to estimate alloy compositions for this kind of quaternary alloys

  17. Medium-energy ion irradiation of Si and Ge wafers: studies of surface nanopatterning and signature of recrystallization in 100 keV Kr+ bombarded a-Si

    2016-03-01

    We report new and exciting experimental results on ion-induced nanopatterning of a-Si and a-Ge surfaces. The crystalline Si (100) and Ge (100) wafers were amorphized and an a/c interface was developed by pre-irradiation with a 50 keV Ar+ beam at normal incidence with an ion fluence of 5.0 × 1015 ions cm-2. These amorphized surfaces were post-irradiated with Ar+ and Kr+ beams at an angle of 60°. The post irradiation was done with ion fluences of 1.0 × 1017 ions cm-2. For each beam, two energies (50 and 200 keV for Ar+, 100 and 250 keV for Kr+) were chosen to ensure ion stopping in both sides of the a/c interface. Regular nanopatterning (in the form of ripples) is observed on the Ge surface only with the post irradiation of the Kr+ beam. The Si surface showed regular nanopatterning with the irradiation of both beams with two energies. For the ion beams crossing the a/c interface, ripples of higher amplitude and longer wavelength were formed. Further, the irradiation with a heavy beam yielded surface ripples of relatively larger amplitudes. The Raman measurements confirm amorphization of the pre-irradiated surfaces. Surprisingly, the post-irradiated Si surface with the 100 keV Kr+ beam showed evidence of recrystallization. In the paper we discuss the physics at the interface and explain the experimental findings.

    Fabrication of p-BaSi2(20nm)/n-Si heterojunction solar cells was performed with different a-Si capping layer thicknesses (da-Si) and varying air exposure durations (tair) prior to the formation of a 70-nm-thick indium-tin-oxide electrode. The conversion efficiencies (η) reached approximately 4.7% regardless of tair (varying from 12-150 h) for solar cells with da-Si = 5 nm. In contrast, η increased from 5.3 to 6.6% with increasing tair for those with da-Si = 2 nm, in contrast to our prediction. For this sample, the reverse saturation current density (J0) and diode ideality factor decreased with tair, resulting in the enhancement of η. The effects of the variation of da-Si (0.7, 2, 3, and 5 nm) upon the solar cell performance were examined while keeping tair = 150 h. The η reached a maximum of 9.0% when da-Si was 3 nm, wherein the open-circuit voltage and fill factor also reached a maximum. The series resistance, shunt resistance, and J0 exhibited a tendency to decrease as da-Si increased. These results demonstrate that a moderate oxidation of BaSi2 is a very effective means to enhance the η of BaSi2 solar cells.

  4. Monte Carlo modelling of a-Si EPID response: The effect of spectral variations with field size and position

    International Nuclear Information System (INIS)

    This study focused on predicting the electronic portal imaging device (EPID) image of intensity modulated radiation treatment (IMRT) fields in the absence of attenuation material in the beam with Monte Carlo methods. As IMRT treatments consist of a series of segments of various sizes that are not always delivered on the central axis, large spectral variations may be observed between the segments. The effect of these spectral variations on the EPID response was studied with fields of various sizes and off-axis positions. A detailed description of the EPID was implemented in a Monte Carlo model. The EPID model was validated by comparing the EPID output factors for field sizes between 1x1 and 26x26 cm2 at the isocenter. The Monte Carlo simulations agreed with the measurements to within 1.5%. The Monte Carlo model succeeded in predicting the EPID response at the center of the fields of various sizes and offsets to within 1% of the measurements. Large variations (up to 29%) of the EPID response were observed between the various offsets. The EPID response increased with field size and with field offset for most cases. The Monte Carlo model was then used to predict the image of a simple test IMRT field delivered on the beam axis and with an offset. A variation of EPID response up to 28% was found between the on- and off-axis delivery. Finally, two clinical IMRT fields were simulated and compared to the measurements. For all IMRT fields, simulations and measurements agreed within 3%--0.2 cm for 98% of the pixels. The spectral variations were quantified by extracting from the spectra at the center of the fields the total photon yield (Ytotal), the photon yield below 1 MeV (Ylow), and the percentage of photons below 1 MeV (Plow). For the studied cases, a correlation was shown between the EPID response variation and Ytotal, Ylow, and Plow

    This report describes work done under a 3-year program to advance ECD`s roll-to-roll, triple-junction photovoltaic manufacturing technologies, to reduce the module production costs, to increase the stabilized module performance, and to expand commercial capacity utilizing ECD technology. The specific 3-year goal is to develop advanced large-scale manufacturing technology incorporating ECD`s earlier research advances with the capability of producing modules with stable 11% efficiency at a cost of approximately $1.00 per peak watt. Accomplishments during Phase 1 included: (1) ECD successfully incorporated a high-performance Ag/metal-oxide back-reflector system into its continuous roll-to-roll commercial production operation. (2) High-quality a-Si-Ge narrow-band-gap solar cells were incorporated into the manufacturing. (3) ECD demonstrated the continuous roll-to-roll production of high-efficiency, triple-junction, two-band-gap solar cells consistently and uniformly throughout a 762-m (2500-ft) run with high yield. (4) ECD achieved 11.1% initial sub-cell efficiency of triple-junction, two-band-gap a-Si alloy solar cells in the production line. (5) The world`s first 0.37-m{sup 2} (4-ft{sup 2}) PV modules were produced utilizing triple-junction spectrum-splitting solar cells manufactured in the production line. (6) As a result of process optimization to reduce the layer thickness and to improve the gas utilization, ECD achieved a 77% material cost reduction for germane and 58% reduction for disilane. Additionally, ECD developed a new low-cost module that saves approximately 30% in assembly material costs.

    Full Text Available Forte de ses liens de parenté culturelle avec les Républiques turcophones d’Asie centrale – Kazakhstan, Kirghizstan, Ouzbékistan, Turkménistan et Tadjikistan –, la Turquie a été le point départ d’un important mouvement migratoire en direction de ces États à partir du début de la décennie 1990, au moment où les États en question recouvraient leur indépendance survenue avec la fin de l’Union soviétique. Multiforme, cette migration a véhiculé un important message religieux, dans les deux sens, mais surtout en provenance de Turquie et à destination des principales villes d’Asie centrale. C’est le principal sujet d’investigation de cette étude. Le commerce et la coopération éducative furent les principaux outils déployés par les migrants turcs partis souvent en tant que missionnaires pour ré-islamiser l’Asie centrale, que de nombreux mouvements islamiques turcs jugeaient devoir être remise dans le giron de la civilisation islamique après plus de soixante-dix ans d’une domination soviétique caractérisée par une politique antireligieuse prononcée. Quatre principaux mouvements islamiques turcs se sont fait remarquer en Asie centrale dans cette œuvre de prosélytisme. Le plus important est sans conteste celui fondé par Sait Nursi dont les disciples ont été très actifs dès 1990 dans l’envoi de littérature islamique en Asie centrale. Par ailleurs, un disciple de Sait Nursi, Fethullah Gülen, a fondé un vaste réseau éducatif animé par des jeunes éducateurs partis d’Anatolie pour s’investir dans différentes villes d’Asie centrale. Une autre mouvance, dite suleymanci, du nom de son fondateur Suleyman Tunahan, a, par le biais de la migration turque, ouvert plusieurs petites madrasas dans divers États d’Asie centrale.

    Full Text Available O presente artigo insere-se em uma linha voltada a investigar as relações entre as instituições, o Estado e o desempenho econômico. Tem como objeto central o estudo dos Estados Desenvolvimentistas (Developmental States, isto é, estados intervencionistas que desempenharam papel central nas estratégias de desenvolvimento de alguns países. A despeito de inúmeras análises históricas sobre essas experiências, o tema é considerado controverso e muitos economistas relutam em aceitar que tais estados tiveram uma contribuição positiva. O artigo lida, portanto, com um tema muito caro à ciência econômica desde os seus primórdios, a relação entre o Estado e o mercado e seus impactos sobre a "riqueza das nações". O presente artigo pretende contribuir para essa temática por meio de uma crítica às análises mais abstratas voltadas a interpretar o modelo asiático e a crise de 1997. Identificando uma falha metodológica nessas análises, argumenta-se que a crise não pode ser deduzida de eventuais fraquezas institucionais do modelo sul coreano. As características institucionais, incluindo o Estado desenvolvimentista e os grandes grupos empresariais, foram variáveis centrais para explicar o grande êxito alcançado pela Coréia do Sul nas décadas que se seguiram a 1960. Nesse sentido, as dificuldades dos anos 1990 devem ser interpretadas como resultado de um processo apressado de liberalização e desregulamentação econômica, implementado antes que uma nova estrutura de regulação estivesse pronta para substituir as formas de coordenação vigentes no período anterior. Ao recusar certas interpretações da crise, o artigo enfatiza a importância de reconhecer as especificidades institucionais dos países e a existência de diferentes tipos de capitalismo. O caso sul coreano, assim como o japonês, ilustra um modelo de capitalismo em que o Developmental State desempenhou um papel muito ativo, constituindo-se em uma vari

    2013-06-01

    Full Text Available L’éthique entrepreneuriale est une notion largement mobilisée dans le milieu des affaires et des entreprises en Asie du Sud-Est où elle est présentée le plus souvent comme un ensemble de préceptes moraux, idéologiques ou religieux que les acteurs locaux rassemblent sous le vocable « valeurs asiatiques ». L’objet de cette introduction est de replacer ces valeurs dans le contexte de l’entreprise à partir de quelques travaux fondateurs de ce sujet en Asie du Sud-Est. Nous verrons que le plus souvent ils oscillent entre deux pôles : d’une part la sociologie wébérienne du capitalisme industriel par le prisme de l’éthique religieuse et d’autre part l’approche substantiviste de Polanyi. Si les grilles d’analyse nées de ces débats ont été appliquées en majorité aux entrepreneurs issus de la diaspora chinoise, c’est la question de l’idéologie des entrepreneurs qui prédomine à travers le prisme des courants philosophiques et religieux qui leur servent de repères.

Attitudes and knowledge in pregnant women differs between the local and immigrant (non-European Union [EU] population. In this study we assessed the choices that pregnant women have with respect to the public and private harvesting system and the main reasons driving their decisions. We examined the ethnic origin of the families and compared tests for syphilis screening and leukocyte (WBC counts in the CB-SC bags that are required for validation of the collection. Methods: Out of a population of 3450 pregnant patients at the Institute for Maternal and Child Health of Trieste, northeast Italy, 772 women agreed to cord blood harvesting and the associated lab tests. Of these, 221 women (28.6% were from immigrant families of non-EU countries. Their ethnic affiliation was recorded, and tests were performed for syphilis screening and for nucleated red blood cell (NRBC interference with the WBC count in CB-SC bags to assess cellularity and to determine if storage was appropriate. Results: Of the 772 pregnant women, 648 (84.0% accessed the public collection system, which is free of charge, and 124 (15.0% accessed the private fee-based system. One woman from the non-EU group opted for the private fee-based system. Of the 3450 pregnant women screened for syphilis at the Institute for Maternal and Child Health, the Treponema pallidum hemagglutination (TPHA and Venereal Disease Research Laboratory (VDRL tests were the main tests performed (66.0% of total cases because many gynecologists in the public harvesting system apply the Italian regulations of the 1988 Decree, while the private system requires tests on syphilis and leaves the option to the lab physicians to select the best

    WHO has targeted yaws for global eradication by 2020. The program goals are to interrupt the transmission in countries where yaws is endemic and to certify countries as yaws free where yaws was endemic in the past. No new rapid plasmin reagin (RPR) seroreactivity in young children is required for certification of elimination at a country level. We sought to evaluate whether antibody responses to specific treponemal antigens measured in a high-throughput multiplex bead array (MBA) assay differentiate past versus current infection and whether a nontreponemal lipoidal antigen test can be incorporated into the MBA. Serum and dried blood spot specimens collected for yaws surveillance projects in Ghana, Vanuatu, and Papua New Guinea (PNG) were run on MBA to measure antibodies against recombinant p17 (rp17) and treponemal membrane protein A (TmpA) treponemal antigens. Results were compared to standard treponemal laboratory (TPPA or TPHA [TPP(H)A]) and quantitative RPR test data. Of 589 specimens, 241 were TPP(H)A(+)/RPR(+), 88 were TPP(H)A(+)/RPR(-), 6 were TPP(H)A(-)/RPR(+), and 254 were negative for both tests. Compared to TPP(H)A, reactive concordance of rp17 was 93.7%, while reactive concordance of TmpA was only 81.9%. TmpA-specific reactivity showed good correlation with RPR titers (R(2) = 0.41; P < 0.0001). IgG responses to the lipoidal antigen used in RPR testing (cardiolipin) were not detected in the MBA. Our results suggest that TmpA can be used as a treponemal antigen marker for recent or active infection and potentially replace RPR in a high-throughput multiplex tool for large-scale yaws surveillance.

    Full Text Available The serological methods for diagnosis of syphilis are classified into non-specific (non-treponemal such as Rapid Plasma Reagin (RPR, and specific (treponemal such as Treponema pallidum hemagglutination test (TPHA and Enzyme-linked immunosorbent assay IgG, IgM (ELISA IgG, IgM tests. The aim of this retrospective study was to estimate and compare the sensitivity and specificity of RPR, TPHA and Syphilis ELISA IgG, IgM. The study was conducted on 18 799 clinically healthy persons who had visited the Outpatient clinic of Ministry of the Interior Clinical Centre, Latvia during 2 years period from August 2006 to November 2007. Patients were screened to find out possible late latent syphilis cases by using RPR, TPHA and ELISA IgG, IgM assays. The results showed the highest sensitivity indices of ELISA IgG, IgM and TPHA methods, and the lowest for the RPR test. Highest specificity indices were observed by using ELISA IgG, IgM method followed by TPHA method with lower values and RPR method showing the lowest specificity. To conclude, ELISA IgG, IgM and TPHA methods should be used for screening late latent syphilis cases and ELISA IgG, IgM for diagnosis confirmation. RPR is not recommended for screening purposes.

    Full Text Available PURPOSE: To analyse the prevalence of syphilis in the apparently healthy population and to provide data for implementation of the joint STD/HIV control programme, a population based study was undertaken by using ′probability proportional to size′ cluster survey method in three randomly chosen districts of Tamil Nadu, India namely Dindigul, Ramnad and Tanjore. METHODS: Blood samples were collected from adults (n=1873 aged 15-45 years, from the selected households enrolled in this study. The sera were tested parallelly by rapid plasma reagin (RPR and Treponema pallidum haemagglutination (TPHA tests. Reactive samples by RPR and/or TPHA were later analysed by fluorescent treponemal antibody absorption (FTA-ABS test. RESULTS: The prevalence of syphilis in the community of Tamil Nadu as per RPR positivity was 2.7% (50/1873 as against 0.7% by TPHA (13/1873. FTA-ABS positivity was observed in only 12 out of 48 (25% RPR/TPHA reactive samples tested. By taking the positivity by two of the three tests, the community prevalence of acute ongoing syphilis in Tamil Nadu was determined as 1.1% (20/1873. CONCLUSIONS: The results confirmed that no single serological test for syphilis can act as the marker of ongoing acute infection in an apparently healthy population. The study suggests that for specific diagnosis of ongoing syphilis, the FTA-ABS test may be performed along with RPR and TPHA.

    One of the main uncertainties in the estimate of the climatic impact of aerosols is linked to our knowledge of gases and aerosols emissions. This is particularly crucial over Asia, where a strong regional fingerprint is observed, with different emission types, depending on the various vegetation and climate conditions (biomass burning emissions) and on the very fast changes of the population and industrialization (biofuel and fossil fuel emissions). The main goal of this work was first to derive a biomass burning inventory for gases and particles over Asia for the 2001 ACE-Asia (Aerosol Characterization Experiment) and TRACE-P (Transport and Chemical Evolution over the Pacific) campaigns (March to May 2001). I implemented a methodology that is the most adapted to my study, and based on the burnt area cartography (GBA-2000 project (Global Burnt Area 2000) [Tansey et al., 2005]). The results of this study, ABBI (Asian Biomass Burning Inventory) [Michel et al., 2005] have been compared with another biomass burning emission inventory (ACESS: ACE-Asia and TRACE-P Modelling and Emission Support System) [Streets et al., 2003], built from fire counts and not from burnt areas. This comparison shows the limits of the use of fire counts in the emission inventory maps and underlines the importance and the relevance of the method used in my study. A comparison with the year 2000 emission inventory, obtained with the same method, underlines the importance of the inter-annual variations. The ABBI inventory has been introduced in the Meso-NH-C mesoscale model combined with an aerosol module: ORISAM (ORganic and Inorganic Spectral Aerosol Module) Bessagnet, 2000]. I have focused in particular on the impact of the burnt vegetation emissions over the asian continent. Comparisons between simulated and ground and airborne measured data showed satisfactory results in some cases, but showed also some limits. Sensitivity tests have been carried out firstly to test the impact of fire

    Full Text Available ABSTRACT Background: Ability to produce breast-milk is to some extent dependent on the storage of material from the mother's food during the prenatal period, as well as on the supply of nutrients from the food she receives during lactation. Objective: To study association of maternal food consumption during pregnancy and the first time breastfeeding after delivery. Methods: We took advantage from a cross-sectional research for Development of Media and Promotional Strategies for Exclusive Breastfeeding in rural and urban West Java, 2006. The analysis is based on 609 mothers who had infants aged 6-12 months in the Bandung city and district, West Java. ‘The first time breastfeeding after delivery’ was identified from the question of ‘how many hours after birth did mother breastfeed her child for the first time’. We used Chi-Square to analyze the association between the mother’s food consumption during prenatal period and the first time breastfeeding after delivery. Results: Mothers who ate more food during pregnancy as much as 1-2 servings per day of pre-pregnancy and the occasional drink of milk to the baby was feeding time less than 3 hours after birth. Whereas mothers who during pregnancy eating just the same as before pregnancy, the first time breastfeeding was longer than 3 hours or even up to 2 days after delivery. The test results obtained was statistically significant difference. Conclusion: Maternal food consumption during pregnancy is significantly associated with the first time breastfeeding after delivery.

    Full Text Available Fort d’un système normatif à la croisée de plusieurs traditions juridiques, le Japon entend participer plus résolument au développement actuel des modes de circulation du droit via notamment sa poli­tique de coopération internationale en matière d’assistance juridique et judiciaire aux pays émergents d’Asie. Cet article examine les particularités de la politique japonaise d’assistance en prenant appui sur des réflexions plus larges concernant les modalités contemporaines d’interaction des normes et le renouvellement des processus d’élaboration du droit. Cela permet de cerner les contradictions d’une assistance juridique conçue à la fois comme outil d’uniformisation du droit et instrument de coordination normative, au service d’une approche pluraliste de la circulation des normes.On the strength of a legal system stemming from various traditions of law, Japan is trying to participate more actively in the current development of the circulation of law, especially through its policy of international cooperation in the field of legal technical assistance and judicial assistance to emerging countries in Asia. This paper scrutinizes the specificities of the Japanese policy in the field drawing on broader analyses about contemporary means of interaction between norms and the reshaping of the processes by which law is elaborated. This may help shed some light on the contradictions of a form legal technical assistance that is conceived both as a tool for the standardization of law and a device that facilitates the coordination of laws at the service of an approach of legal pluralism.

    Full Text Available De nos jours, la notion d’anglicité est devenue cruciale tant pour le Royaume-Uni que pour les nombreux pays du monde, dans lesquels vivent des citoyens libres et indépendants, qui participent à sa définition. La relation à la culture anglophone, en particulier en Asie, est le produit de l’histoire, et les relations politiques qu’entretiennent les pays indépendants avec l’ancienne métropole se déclinent de façon extrêmement variée, tant dans leur relation à la langue anglaise en tant que moyen de communication que dans la notion d’ethnicité. Le roman de Paul Theroux, Kowloon Tong (1998, en est un bon exemple. Il explore les conséquences du retrait brutal et affligeant d’une compagnie de textile anglais lors de la cession de Hong Kong à la Chine en 1997. Alliant les genres du roman historique, détective et sentimental, il met en scène l’opposition entre les valeurs traditionnelles britanniques qui se retirent et celles de la nouvelle classe dominante chinoise. Yasmine Gooneratne, écrivain du Sri Lanka, insiste, elle aussi, sur les conflits culturels, soit en s’inspirant du thème de son propre déplacement de Colombo à Sydney, en opposant au tourisme de masse les formes enchanteresses du folklore d’autrefois, ou encore en proposant une rencontre entre un riche héritage colonial et l’indépendance toute récente du Sri Lanka des années cinquante et soixante. Ainsi se creuse chez les écrivains contemporains une distance grandissante vis-à-vis de ce que furent au cours des siècles passés les valeurs incontestées de l’anglicité.

    Full Text Available Les mouvements multiformes de populations en Asie du Sud-Est, sont le résultat de guerres, de tracés de frontières, de conflits ethniques… Réfugiés, immigrés (légaux et illégaux ou déplacés, on ne compte plus les problèmes des États de la région pour gérer les flux de populations, notamment transfrontaliers. Ces derniers, de plus en plus importants, résultent de la conjonction de plusieurs facteurs, notamment l’ouverture des pays au commerce, la volonté de « régionaliser » l’Asie du Sud-Est et les déséquilibres économiques entre les pays. Pourquoi et comment les frontières modernes facilitent ces mouvements de populations, de quelques milliers de nomades vivant sur les frontières de plusieurs pays à des millions de travailleurs illégaux venus chercher un avenir dans un pays d’accueil. Par exemple, en dépit de l’imposition de règles administratives de plus en plus contraignantes, la porosité des frontières et les réseaux multiséculaires de certaines régions permettent une « inflation » des mouvements de populations. En trente ans, le nombre de réfugiés et de travailleurs immigrés dans le sud de la Thaïlande est passé de quelques centaines de milliers à plusieurs millions. La question des minorités se pose moins en termes de chiffres que d’identité. Les États-nations de la région n’arrivent pas à intégrer leurs populations frontalières. Les questions essentielles – qui est citoyen de tel ou tel pays et selon quels critères – sont loin d’être résolues. Les agences nationales et les Ong ont mis en œuvre des moyens pour gérer le flux et l’ambiguïté délibérément maintenue par les gouvernements sur des statuts des réfugiés et des travailleurs illégaux pour contrôler, selon leurs besoins, ces millions de personnes.

    The product test asks the product of a quantity index number and a price index number to equal the corresponding value change. The literature treats the product test as being so important that it is used to identify acceptable index number pairs, and to construct implicit index numbers when an otherwise desirable pair fails the test. We treat the product test as a hypothesis to be tested, and we provide an empirical application.

    Full Text Available Presently, the diagnosis of syphilis is dependent mainly on serological tests. The most widely used screening tests for syphilis are the VDRL and the rapid plasma reagin (RPR and for confirmation, the fluorescent treponemal antibody (FTA and the treponema pallidum hemagglutination (TPHA tests. The four alternative modes for diagnosis of syphilis can be a VDRL + FTA, b VDRL + TPHA, c RPR + FTA and d RPR + TPHA. Here the author reports an evaluation of cost utility of these tests in medical practice. It is shown that the cost per accurate diagnosis with VDRL + TPH is the least expensive choice. Therefore, this alternative is the best method for serological diagnosis for syphilis, based on medical laboratory economics principles

    The optimal use of the various forms of solar energy (passive, active, daylighting, photovoltaics) in buildings calls for an optimal integration of the technologies. As energy conservation potential in space heating may soon be exhausted, electricity efficiency and on-site generation will play an increasing role in energy-conscious building design. There, dispersed PV systems integrated into buildings show a significant market potential, due to a number of benefits: no extra land area is required, PV-array may replace conventional cladding materials and become a building element. Moreover, the produced PV-electricity is more valuable for the building owner than for an electric utility

    Serological assays are still considered the most useful tests in the diagnosis of syphilis. Since no single serological assay is able to provide a satisfactory result, in our laboratory we have evaluated the usefulness of a commercially-available immunoblot to diagnose syphilis infection among blood donors. From October 2012 to June 2013, 4572 blood donors were screened for syphilis with an automated chemiluminescent microparticle immunoassay (CMIA). To confirm the presence of treponemal antibodies, CMIA-reactive sera were tested by standard Treponema pallidum haemagglutination assay (TPHA). In addition, an alternative confirmatory test - the immunoblot INNO-LIA assay was introduced in our laboratory. Since two additional positives among CMIA-reactive-TPHA-negative samples were found, we concluded that the INNO-LIA immunoblot allowed a better detection of syphilis compared to TPHA. A confirmatory strategy based on the use of two treponemal assays could meet the screening requirements for blood donors as well as in our centre. PMID:26068964

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST, was developed by the World Health Organization to detect substance use disorders. The present study evaluates the psychometric properties of the French version of ASSIST in a sample of elderly people attending geriatric outpatient facilities (primary care or psychiatric facilities. Methods One hundred persons older than 65 years were recruited from clients attending a geriatric policlinic day care centre and from geriatric psychiatric facilities. Measures included ASSIST, Addiction Severity Index (ASI, Mini-International Neuropsychiatric Interview (MINI-Plus, Alcohol Use Disorders Identification Test (AUDIT, Revised Fagerstrom Tolerance Questionnaire-Smoking (RTQ and MiniMental State(MMS. Results Concurrent validity was established with significant correlations between ASSIST scores, scores from ASI, AUDIT, RTQ, and significantly higher ASSIST scores for patients with a MINI-Plus diagnosis of abuse or dependence. The ASSIST questionnaire was found to have high internal consistency for the total substance involvement along with specific substance involvement as assessed by Cronbach’s α, ranging from 0.66, to 0.89 . Conclusions The findings demonstrate that ASSIST is a valid screening test for identifying substance use disorders in elderly.

    Full Text Available Introduction: The clinical diagnosis of syphilis is always supported by appropriate laboratory tests and the test results are interpreted with reference to the patient’s history. In the diagnosis of syphilis, the use of tests based on antibody search that recognize both treponemal and reaginic antigens increases the diagnostic chances. Our study discusses the various serological and alternative tests currently available along with their limitations, and relates their results to the likely corresponding clinical stage of the disease. Methods: in our laboratory were analyzed 264 sera and 4 liquor (123 Females, 145 Males. 187 patients are subject at low risk for luetic infection, including pregnant woman, patient with organ transplant, outpatients or hospitalized undergoing routine serological, and 81 from patients with confirmed syphilis including 4 pregnant women in antibiotic treatment, patients with suspected disease, HIV positive and patients with autoimmune diseases with Cardiolipin positive. All sera were tested with ELISA Anti-Treponema pallidum Screen (IgG / IgM and in parallel with agglutination tests VDRL and TPHA. On all positive sera was tested Euroline-WB EUROIMMUN and reading done with the program EuroLineScan. Results: by ELISA Anti-Treponema pallidum Screen IgG / IgM 162 sera were negative and 106 sera positive (39.5%, distributed as follows: 45 (42% with a value greater than 200 RU / ml, 43 (41% with a value> 22 RU / ml and 18 (17% with a borderline value between> 16 to <22 RU / ml.

  2. X-ray tests of a microchannel plate detector and amorphous silicon pixel array readout for neutron radiography

    International Nuclear Information System (INIS)

    High-performance large area imaging detectors for fast neutrons in the 5-14 MeV energy range do not exist at present. The aim of this project is to combine microchannel plates or MCPs (or similar electron multiplication structures) traditionally used in image intensifiers and X-ray detectors with amorphous silicon (a-Si) pixel arrays to produce a composite converter and intensifier position sensitive imaging system. This detector will provide an order of magnitude improvement in image resolution when compared with current millimetre resolution limits obtained using phosphor or scintillator-based hydrogen rich converters. In this study we present the results of the initial experimental evaluation of the prototype system. This study was carried out using a medical X-ray source for the proof of concept tests, the next phase will involve neutron imaging tests. The hybrid detector described in this study is a unique development and paves the way for large area position sensitive detectors consisting of MCP or microsphere plate detectors and a-Si or polysilicon pixel arrays. Applications include neutron and X-ray imaging for terrestrial applications. The technology could be extended to space instrumentation for X-ray astronomy

Em placas controles foi adicionado 1mL de água. Sobre as placas foram adicionados 100µL de urediniósporos na concentração de 5 mg/mL de água. As placas foram incubadas por 4 horas a 25ºC e logo depois avaliada a porcentagem de germinação. Na segunda etapa, em casa-de-vegetação, os óleos foram aplicados nas mesmas concentrações em plantas de soja, cultivares MG/BR46 (Conquista e Suprema, aos 7 dias antes, 15 e 30 dias depois da inoculação. Os parâmetros avaliados foram incidência e número de pústulas por cm² de área foliar. Foram também coletadas folhas para preparação de amostras para microscopia eletrônica de varredura (MEV. Constatou-se que os óleos nas concentrações utilizadas inibiram 100% a germinação dos urediniósporos em meio ágar-água. Em casa-de-vegetação observou-se que todos os óleos retardaram a evolução da doença quando comparado com o controle, sendo que a severidade foi reduzida em média de 34,6 a 60,7% na cultivar MG/BR46 (Conquista e de 45,7 a 62, 3% na cultivar Suprema, em relação ao controle. Nas observações em MEV observou-se que houve murchamento dos urediniósporos, quando tratados com óleo de tomilho. Para os demais tratamentos observou-se apenas redução no tamanho das urédias. Com isso podemos inferir que os óleos essenciais utilizados têm potencial para reduzir o ataque do fungo em plantas

    1996-08-23

    On August 6, 1996, the Food and Drug Administration (FDA) approved the first urine test to detect HIV antibodies. The FDA states that the urine test, developed by Calypte Biomedical Corp. of Berkeley, CA, should not be used to screen donors at blood banks and should be used only as a supplemental diagnostic tool because it is not as accurate as the standard blood-based test. The test, for use only by health care professionals and insurance companies, will be marketed by Seradum Inc. of Indianapolis under the trade name Sentinel. The price will be $40 to $50, comparable to the recently approved saliva-based tests. Advocates of the urine test say it is safer, easier, and less intrusive than blood testing. Critics say the tests are too unreliable and fear that the urine samples used in drug testing in the workplace also could be used to screen out HIV-positive job applicants. PMID:11363733

    International Nuclear Information System (INIS)

    This document discusses inservice testing of safety-related components at nuclear power plants which is performed under the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (the Code). Subsections IWP and IWV of Section XI of the Code state test method and frequency requirements for pumps and valves respectively. Tests vary greatly in quality and frequency. This paper explores the concept of test quality and its relationship with operational readiness and preventive maintenance. This paper also considers the frequencies of component testing. Test quality is related to a test's ability to detect degradation that can cause component failure. The quality of the test depends on several factors, including specific parameters measured, system or component conditions, and instrument accuracy. The quality of some currently required tests for check valves, motor-operated valves, and pumps is also discussed. Suggestions are made to improve test quality by measuring different parameters, testing valves under load, and testing positive displacement pumps at high pressure and centrifugal pumps at high flow rate conditions. These suggestions can help to improve the level of assurance of component operational readiness gained from testing

    Full Text Available Dengue emerged as a public health burden in Southeast Asia during and following the Second World War and has become increasingly important, with progressively longer and more frequent cyclical epidemics of dengue fever/dengue hemorrhagic fever. Despite this trend, surveillance for this vector-borne viral disease remains largely passive in most Southeast Asian countries, without adequate laboratory support. We review here the factors that may have contributed to the changing epidemiology of dengue in Southeast Asia as well as challenges of disease prevention. We also discuss a regional approach to active dengue virus surveillance, focusing on urban areas where the viruses are maintained, which may be a solution to limited financial resources since most of the countries in the region have developing economies. A regional approach would also result in a greater likelihood of success in disease prevention since the large volume of human travel is a major factor contributing to the geographical spread of dengue viruses.A dengue emergiu como problema de saúde pública no Sudeste Asiático durante e após a Segunda Guerra Mundial, e vem se agravando cada vez mais, com epidemias cíclicas progressivamente mais longas e freqüentes de dengue e de febre hemorrágica da dengue. Apesar dessa tendência, a vigilância dessa virose transmitida por vetores permanece basicamente passiva na maioria dos países do Sudeste Asiático, sem apoio laboratorial adequado. O artigo apresenta uma revisão dos fatores que podem ter contribuído para a mudança no perfil epidemiológico da dengue na região, além de discutir os desafios para a prevenção da doença. Analisa-se também uma abordagem regional para a vigilância ativa dos vírus da dengue, focando as áreas urbanas onde eles se mantêm, o que pode representar uma solução à limitação de recursos financeiros, uma vez que a maioria dos pa��ses da região tem economias em desenvolvimento.

    Analytical methods for combining flight acceleration and strain data with shake test mobility data to predict the effects of structural changes on flight vibrations and strains are presented. This integration of structural dynamic analysis with flight performance is referred to as analytical testing. The objective of this methodology is to analytically estimate the results of flight testing contemplated structural changes with minimum flying and change trials. The category of changes to the aircraft includes mass, stiffness, absorbers, isolators, and active suppressors. Examples of applying the analytical testing methodology using flight test and shake test data measured on an AH-1G helicopter are included. The techniques and procedures for vibration testing and modal analysis are also described.

    We give a brief derivation of the trace test to verify completeness of a partial witness set of an irreducible variety in affine or projective space. We then consider the trace test for subvarieties of products of projective spaces working with multihomogeneous witness sets. We show how a dimension reduction based on Bertini's Theorem leads to a practical trace test in this case involving a curve in a small-dimensional affine space.

    Now more than ever, scientific results are dependent on sophisticated software and analysis. Why should we trust code written by others? How do you ensure your own code produces sensible results? How do you make sure it continues to do so as you update, modify, and add functionality? Software testing is an integral part of code validation and writing tests should be a requirement for any software project. I will talk about Python-based tools that make managing and running tests much easier and explore some statistics for projects hosted on GitHub that contain tests.

    For the proper performance of ultrasonic testing of steel welded joints, and anisotropic material it is necessary to have sound understanding on the underlying physics. To provide such an understanding, it is beneficial to have simulation tools for ultrasonic testing. In order to address such a need, we develop effective approaches to simulate angle beam ultrasonic testing with a personal computer. The simulation is performed using ultrasonic measurement models based on the computationally efficient multi-Gaussian beams. This reach will describe the developed ultrasonic testing models together with the experimental verification of their accuracy.

    Full Text Available Presence of genital ulcer disease facilitates human immunodeficiency virus (HIV transmission and their -diagnosis is essential for the proper management. Venereal Disease Research Laboratory (VDRL test is used as a screening test for the diagnosis of syphilis. However, unusual VDRL test results have been reported in HIV-infected persons with syphilis. There are reports showing higher than expected VDRL titers as well as biological false positive in most of the studies. A negative Rapid Plasma Reagin (RPR test or VDRL test result may not rule out syphilis in patients with HIV infection. For laboratory confirmation of syphilis, one specific Treponemal test, namely, Fluroscent Treponemal Antibody Absorption (FTA-ABS test or Treponema Pallidum Haemagglutination Assay (TPHA should be done along with VDRL. In the present study, 88 HIV-seropositive patients with history of high-risk behaviour were screened for syphilis by VDRL test. Out of these 88 cases, 42 (47.7% patients were positive for TPHA and eight (9.1% patients were reactive for VDRL in various titers. All the eight patients who were reactive for VDRL test were also positive for TPHA test. Persons with HIV infection acquired through sexual route should be screened for sexually transmitted infections (STIs, and all patients with STIs should be counselled for HIV testing. This will help in proper management of patients having STIs and HIV coinfection.

    Frequency of syphilis among pregnant women attending Combined Military Hospital Abbottabad Study Design: Descriptive study. Material and Methods: A screening for syphilis of 500 married pregnant women presenting to antenatal clinics was carried out using the qualitative Rapid Plasma Regent (RPR) test/ Venereal Disease Research Laboratory (VDRL) test. The Treponema Palladium Haem-Agglutination Assay (TPHA) test was used as confirmatory test for all Venereal Disease Research Laboratory (VDRL) test positive cases. Results: A total of 8 women (1.6%) were positive for Venereal Disease Research Laboratory (VDRL) test. Out of these 4 (0.8%) were positive for Treponema Palladium Haem-Agglutination Assay (TPHA) test. All of these cases have bad obstetrical history. Conclusion: The sero-positivity of Venereal Disease Research Laboratory (VDRL) test is (1.6%), considered high among pregnant women reporting in obstetrics clinics of Combined Military Hospital Abbottabad. Similarly sero-positivity of Treponema Palladium Haem-Agglutination Assay (TPHA) test is (0.8%) considered high among the Venereal Disease Research Laboratory (VDRL) test population. Therefore Screening of syphilis in pregnancy especially in patients having bad obstetrical history (BOH) should be incorporated into the study. (author)

    Full Text Available Dentro de la estructura internacional de hoy en día existen tres centros que se han ido configurando como importantes polos de desarrollo: América, Europa y Asia. De los tres, este último es quizás el más débil, aunque también se presenta como una región de grandes oportunidades. A partir de la configuración de APEC, a finales de los ochenta, Asia ha intentado establecer relaciones con la cuenca del Pacífico y, a partir 1996, con Europa, su relación más débil dentro de este esquema tripolar. Si en Europa el núcleo de la región es la Unión Europea, en América lo es el NAFTA, que reúne a Estados Unidos, México y Canadá y que podría convertirse en el embrión de una gran área de libre comercio en las Américas (ALCA. En Asia, aún no existe un núcleo formal. Este artículo describe como la región se encuentra en un proceso de formación de su identidad, y como de su resultado depende la posición y relaciones que se darán entre los tres polos ya mencionados

    Full Text Available The simple state which is shown with zero form unit in Turkish is a type of state incorporating language units that are at position of subject. Therefore only the language units that assume "noun” and “pronoun” functions are able to stay in simple state. Even if they are of noun origin, because adjectives, adverbs, prepositions, conjunctions and exclamations can not enter into noun state inflection, they do not show the characteristic of simple state. However the language units having assumed the function of a noun may only enter into simple state inflection if they undertake the function of indicating the work, event, rendering and one who performs the action, establishing a connection with the verb.

    This study aims to psychometrically validate the Chilean version of the Alcohol, Smoking and Substance Involvement Screening Test ASSIST. Specifically, this study is interested in evaluating the reliability, consistency and concurrent and discriminant validity of this instrument. The sample was composed for a total of 400 people from four different settings: treatment centers (residential and ambulatories), primary health care, police stations and companies. The reliability of the ASSIST was high (α = .86 for Alcohol, α = .84 for marijuana and α = .90 for cocaine). The intra class correlation coefficient (ICC) with test-retest comparison was statistically significant for Alcohol (ICC = .66), marijuana (ICC = .74) and cocaine (ICC = .80). There were statistically significant correlations between the ASSIST and the AUDIT score (Pearson’s r = .85), the ASSIST and the ASI-Lite score (r between .66 and .83 for tobacco, alcohol, marijuana and cocaine), and the ASSIST and the SDS score (r = .65). The original cutoff point for high risk detection was 27 points, however, in order to have a better balance between sensitivity and specificity the cut was changed to 21 points. The ASSIST presents good psychometric properties and therefore is a reliable and valid instrument to be used as a mechanism to detect risk levels of substance use in the Chilean population.

    Full Text Available The Afro-Asian freshwater copepod Mesocyclops aspericornis (Daday, 1906, deemed as an exotic species in the Americas, is known to occur disjunctly in Mexico, South America, and the insular Caribbean. Adult females of this species were recorded.from samples collected in the state of Veracruz, on the Atlantic coast of Mexico.The morphology of these specimens is identical in most characters to those described or depicted in previous taxonomic accounts. The 3 known Mexican populations belong to the "western" group of M. aspericornis. The subtle morphological variations among the Mexican populations and their isolation suggest that each could be the result of independent events of dispersion or introduction via aquaculture. This is the third confirmed report of M. aspericornis in Mexico, but the first one in the Atlantic side of Middle America. The states of Tabasco and Chiapas harbour 3 of the 4 species of exotic freshwater copepods known to occur in Mexico.El copépodo dulceacuícola afro-asiático Mesocyclops aspericornis (Daday, 1906, considerado como especie exótica en América, se sabía presente de modo disperso en México, Sudamérica y en las islas del Caribe.

La morfología de estos ejemplares es idéntica en la mayoría de los caracteres a la descrita o ilustrada en trabajos taxonómicos previos. Las 3 poblaciones conocidas en México pertenecen al grupo "occidental" de M. aspericornis. Las sutiles variaciones morfológicas entre las poblaciones mexicanas y su aislamiento sugieren que cada una podría ser resultado de eventos independientes por dispersión o introducción vía la acuacultura.

    Sera from 608 wild rabbits were examined using serological tests for syphilis as an indicator of infection with Treponema paraluis-cuniculi. Only eight sera gave positive or weakly positive results in the rapid plasma reagin (RPR) test, and none of these eight sera gave positive results in the Treponema pallidum haemagglutination assay (TPHA). Thus, it appears that wild rabbit populations in Victoria, Australia, are not naturally infected with T paraluis-cuniculi. Normal Australian laboratory...

    Uncooled infrared focal plane array (UIRFPA) detectors are widely used in industrial thermography cameras, night vision goggles, thermal weapon sights, as well as automotive night vision systems. To meet the market requirement for smaller pixel pitch and higher resolution, we have developed a 17um pitch 640x480 UIRFPA detector. The detector is based on amorphous silicon (a-Si) microbolometer technology, the readout integrated circuit (ROIC) is designed and manufactured with 0.35um standard CMOS technology on 8 inch wafer, the microbolometer is fabricated monolithically on the ROIC using an unique surface micromachining process developed inside the company, the fabricated detector is vacuum packaged with hermetic metal package and tested. In this paper we present the design, fabrication and testing of the 17um 640x480 detector. The design trade-off of the detector ROIC and pixel micro-bridge structure will be discussed, by comparison the calculation and simulation to the testing results. The novel surface micromachining process using silicon sacrificial layer will be presented, which is more compatible with the CMOS process than the traditional process with polyimide sacrificial layer, and resulted in good processing stability and high fabrication yield. The performance of the detector is tested, with temperature equivalent temperature difference (NETD) less than 60mK at F/1 aperture, operability better than 99.5%. The results demonstrate that the detector can meet the requirements of most thermography and night vision applications.

    Auxiliary Power Unit (APU) fuel (hydrazine) tanks have had to be removed from the Columbia Shuttle (OV-102) because they have been in service for 11 years, which is the limit of their useful life. As part of an effort to determine whether the useful life of the fuel tanks can be extended, examination of the ethylene propylene rubber (EPR) diaphragm and the metal from one of the APU tanks is required. The JSC Propulsion and Power Division has requested White Sands Test Facility (WSTF) to examine the EPR diaphragm thoroughly and the metal casing generally from one tank. The objective is to examine the EPR diaphragm for signs of degradation that may limit the life of its function in the APU propellant tank. The metal casing will also be examined for signs of surface corrosion.

    Full Text Available The temperature dependence coefficients of amorphous silicon and crystalline photovoltaic (PV modules using Malaysian field data have been obtained using linear regression technique. This is achieved by studying three test stand-alone PV-battery systems using 62 Wp a-Si, 225 Wp multi-crystalline and 225 Wp mono-crystalline PV modules. These systems were designed to provide electricity for rural domestic loads at 200 W, 500 W and 530 W respectively. The systems were installed in the field with data monitored using data loggers. Upon analysis, the study found that the normalized power output per operating array temperature for the amorphous silicon modules, multi-crystalline modules and mono-crystalline modules were: +0.037 per°C, +0.0225 per °C and +0.0263 per °C respectively. In addition, at a solar irradiance value of 500 Wm-2, the current, voltage, power and efficiency dependence coefficients on operating array temperatures obtained from linear regression were: +37.0 mA per °C, -31.8 mV per °C, -0.1036 W per °C and -0.0214% per °C, for the a-Si modules, +22.5 mA per °C, -39.4 mV per °C, -0.2525 W per °C, -0.072 % per °C for the multi-crystalline modules and +26.3 mA per °C, -32.6 mV per °C, -0.1742 W per °C, -0.0523 % per °C for the mono-crystalline modules. These findings have a direct impact on all systems design and sizing in similar climate regions. It is thus recommended that the design and sizing of PV systems in the hot and humid climate regions of the globe give due address to these findings.

    Tlomak, Pawel; Hausgen, Paul E.; Merrill, John; Senft, Donna; Piszczor, Michael F., Jr.

    2007-01-01

    This paper gives an overview of the space plasma test program for thin-film photovoltaics (TFPV) technologies developed at the Air Force Research Laboratory (AFRL). The main objective of this program is to simulate the effects of space plasma characteristic of LEO and MEO environments on TFPV. Two types of TFPV, amorphous silicon (a-Si) and copper-indium-gallium-diselenide (CIGS), coated with two types of thin-film, multifunctional coatings were used for these studies. This paper reports the results of the first phase of this program, namely the results of preliminary electrostatic charging, arcing, dielectric breakdown, and collection current measurements carried out with a series of TFPV exposed to simulated space plasma at the NASA Glenn Plasma Interaction Facility. The experimental data demonstrate that multifunctional coatings developed for this program provide effective protection against the plasma environment while minimizing impact on power generation performance. This effort is part of an ongoing program led by the Space Vehicles Directorate at the AFRL devoted to the development and space qualification of TFPV and their protective coatings.

O presente trabalho teve como objetivo avaliar o controle químico da ferrugem asiática e a deposição da calda fungicida aplicada na cultura da soja, em função de diferentes volumes de aplicação e de tipos de ponta de pulverização. O ensaio foi conduzido no delineamento em blocos ao acaso, com quatro repetições, em esquema bifatorial (4 x 2 + 1: quatro tipos de ponta de pulverização (jato plano padrão, jato plano de pré-orifício, jato plano de indução de ar e jato plano duplo de indução de ar, dois volumes de aplicação (115 e 160L ha-1 e um tratamento adicional, que não recebeu fungicida (testemunha. Realizou-se a semeadura direta da cultivar "Emgopa 313" (ciclo tardio, avaliando-se, após a aplicação do fungicida tebuconazole com as diferentes pontas e volumes, a deposição de calda no dossel da cultura, a severidade da ferrugem e a produtividade. Constatou-se que, apesar de o volume de calda de 160L ha-1 e de a utilização da ponta de jato plano padrão terem proporcionado maior uniformidade de distribuição da calda fungicida nas plantas, não houve influência do tipo de ponta de pulverização e do volume de aplicação no controle da ferrugem e na produtividade da cultura da soja. O fungicida tebuconazole propiciou bom controle da ferrugem, refletindo na produtividade de grãos, que foi, em média, 41% superior à obtida na testemunha.The spray nozzles are one of the most important components of pesticide hydraulic sprayers. This study aimed at evaluating the chemical control of the rust and the deposition of fungicide sprayed on soybean concerning different nozzles, and application volumes.

  8. Design Driven Testing Test Smarter, Not Harder

    CERN Document Server

    Stephens, M

    2010-01-01

    The groundbreaking book Design Driven Testing brings sanity back to the software development process by flipping around the concept of Test Driven Development (TDD) - restoring the concept of using testing to verify a design instead of pretending that unit tests are a replacement for design. Anyone who feels that TDD is "Too Damn Difficult" will appreciate this book. Design Driven Testing shows that, by combining a forward-thinking development process with cutting-edge automation, testing can be a finely targeted, business-driven, rewarding effort. In other words, you'll learn how to test

    Background: Student's two-sample t test is generally used for comparing the means of two independent samples, for example, two treatment arms. Under the null hypothesis, the t test assumes that the two samples arise from the same normally distributed population with unknown variance. Adequate...... control of the Type I error requires that the normality assumption holds, which is often examined by means of a preliminary Shapiro-Wilk test. The following two-stage procedure is widely accepted: If the preliminary test for normality is not significant, the t test is used; if the preliminary test rejects...... the null hypothesis of normality, a nonparametric test is applied in the main analysis. Methods: Equally sized samples were drawn from exponential, uniform, and normal distributions. The two-sample t test was conducted if either both samples (Strategy I) or the collapsed set of residuals from both samples...

    1997-08-01

    This document outlines the test results for the strength tests of the CANFLEX fuel bundle. Strength tests are performed to determine and verify the amount of the bundle shape distortion which is against the side-stops when the bundles are refuelling. There are two cases of strength test; one is the double side-stop test which simulates the normal bundle refuelling and the other is the single side-stop test which simulates the abnormal refuelling. the strength test specification requires that the fuel bundle against the side-stop(s) simulators for this test were fabricated and the flow rates were controlled to provide the required conservative hydraulic forces. The test rig conditions of 120 deg C, 11.2 MPa were retained for 15 minutes after the flow rate was controlled during the test in two cases, respectively. The bundle loading angles of number 13- number 15 among the 15 bundles were 67.5 deg CCW and others were loaded randomly. After the tests, the bundle shapes against the side-stops were measured and inspected carefully. The important test procedures and measurements were discussed as follows.

  4. Prevalence and risk factors of syphilis infection among drug addicts

    Directory of Open Access Journals (Sweden)

    Kuhlmann Thomas

    2005-05-01

    Full Text Available Abstract Background Recent epidemiological data show an increased trend of official estimates for syphilis infection in the general population. Many of the infected cases remain undetected leaving an underestimation of the true prevalence of syphilis in the general population, but also among subpopulations such as illicit drug users. There is limited epidemiological data published on the proportion and risk factors of syphilis infections associated with illicit drug abuse. Methods Illicit drug addicts (n = 1223 in inpatients units in Germany were screened (2000–01 for syphilis and interviewed regarding patterns of drug use and sexual behaviour. TPHA-test for initial screening and FTA-ABS-IgM test in TPHA-positive patients were used. Results In total, TPHA-tests were positive in 39 (3.3% and 7 patients (0.6% were IgM positive. The prevalence rate for syphilis in males was 1.9% and for women it was 8.5%. Female patients were 4.56 (CI 95% 2.37–8.78 times more likely to have a positive TPHA test than males. Sexual behaviours such as high number of sexual partners, sex for drugs/money, sex on the first day were associated with syphilis infection only in women. Females with frequent sex for drugs or money had 4.31 (CI 95% 2.32–8.52 times more likely a reactive TPHA test than remaining patients. Neither the sociodemographic factors nor sexual behaviour were statistically significant associated with syphilis infection among men at all. Conclusion Our data suggest the need for screening for syphilis among these illicit drug users in inpatient settings, in particular among sexual active women. This conclusion is corroborated by the finding of increasing numbers of syphilis infections in the general population. The identification of syphilis cases among drug addicts would give treatment options to these individuals and would help to reduce the spread of infection in this population, but also a spread into heterosexual populations related to

  5. SU-C-304-02: Robust and Efficient Process for Acceptance Testing of Varian TrueBeam Linacs Using An Electronic Portal Imaging Device (EPID)

    International Nuclear Information System (INIS)

    Purpose: The purpose of this project was to develop a process that utilizes the onboard kV and MV electronic portal imaging devices (EPIDs) to perform rapid acceptance testing (AT) of linacs in order to improve efficiency and standardize AT equipment and processes. Methods: In this study a Varian TrueBeam linac equipped with an amorphous silicon based EPID (aSi1000) was used. The conventional set of AT tests and tolerances was used as a baseline guide, and a novel methodology was developed to perform as many tests as possible using EPID exclusively. The developer mode on Varian TrueBeam linac was used to automate the process. In the current AT process there are about 45 tests that call for customer demos. Many of the geometric tests such as jaw alignment and MLC positioning are performed with highly manual methods, such as using graph paper. The goal of the new methodology was to achieve quantitative testing while reducing variability in data acquisition, analysis and interpretation of the results. The developed process was validated on two machines at two different institutions. Results: At least 25 of the 45 (56%) tests which required customer demo can be streamlined and performed using EPIDs. More than half of the AT tests can be fully automated using the developer mode, while others still require some user interaction. Overall, the preliminary data shows that EPID-based linac AT can be performed in less than a day, compared to 2–3 days using conventional methods. Conclusions: Our preliminary results show that performance of onboard imagers is quite suitable for both geometric and dosimetric testing of TrueBeam systems. A standardized AT process can tremendously improve efficiency, and minimize the variability related to third party quality assurance (QA) equipment and the available onsite expertise.

    2005-01-01

    The Idaho National Laboratory (INL) prepared this generic test plan to provide clients (vendors, end users, program sponsors, etc.) with a sense of the scope and depth of vulnerability testing performed at the INL’s Supervisory Control and Data Acquisition (SCADA) Test Bed and to serve as an example of such a plan. Although this test plan specifically addresses vulnerability testing of systems applied to the energy sector (electric/power transmission and distribution and oil and gas systems), it is generic enough to be applied to control systems used in other critical infrastructures such as the transportation sector, water/waste water sector, or hazardous chemical production facilities. The SCADA Test Bed is established at the INL as a testing environment to evaluate the security vulnerabilities of SCADA systems, energy management systems (EMS), and distributed control systems. It now supports multiple programs sponsored by the U.S. Department of Energy, the U.S. Department of Homeland Security, other government agencies, and private sector clients. This particular test plan applies to testing conducted on a SCADA/EMS provided by a vendor. Before performing detailed vulnerability testing of a SCADA/EMS, an as delivered baseline examination of the system is conducted, to establish a starting point for all-subsequent testing. The series of baseline tests document factory delivered defaults, system configuration, and potential configuration changes to aid in the development of a security plan for in depth vulnerability testing. The baseline test document is provided to the System Provider,a who evaluates the baseline report and provides recommendations to the system configuration to enhance the security profile of the baseline system. Vulnerability testing is then conducted at the SCADA Test Bed, which provides an in-depth security analysis of the Vendor’s system.b a. The term System Provider replaces the name of the company/organization providing the system

  16. Localizing Test Power Consumption for Scan Testing

    Institute of Scientific and Technical Information of China (English)

    XIANG Dong; LI Kai-wei

    2005-01-01

    A two stage scan architecture is proposed to do low powerand low test application cost scan testing. The first stage includes multiple scan chains, where each scan chain is driven by a primary input. Each scan flip-flop in the multiple scan chains drives a group of scan flip-flops. The scan flip-flop in the multiple scan chain and the scan flipflop driven by it are assigned the same values for all test vectors. Scan flip-flops in the multiple scan chains and those in the second stage use separate clock signals, but the design for testability technqiue needs only one clock. The proposed scan architecture localizes test power consumption to the multiple scan chains during test application. Test signals assigned to scan flip-flops in the multiple scan chains are applied to the scan flip-flops in the second stage after the test vector has been applied to the multiple scan chains. This technique can make test power consumption very small.

    The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

  4. Irradiation effects test series, test IE-5. Test results report

    International Nuclear Information System (INIS)

    Test IE-5, conducted in the Power Burst Facility at the Idaho National Engineering Laboratory, employed three 0.97-m long pressurized water reactor type fuel rods, fabricated from previously irradiated zircaloy-4 cladding and one similar rod fabricated from unirradiated cladding. The objectives of the test were to evaluate the influence of simulated fission products, cladding irradiation damage, and fuel rod internal pressure on pellet-cladding interaction during a power ramp and on fuel rod behavior during film boiling operation. The four rods were subjected to a preconditioning period, a power ramp to an average fuel rod peak power of 65 kW/m, and steady state operation for one hour at a coolant mass flux of 4880 kg/s-m2 for each rod. After a flow reduction to 1800 kg/s-m2, film boiling occurred on one rod. Additional flow reductions to 970 kg/s-m2 produced film boiling on the three remaining fuel rods. Maximum time in film boiling was 80s. The rod having the highest initial internal pressure (8.3 MPa) failed 10s after the onset of film boiling. A second rod failed about 90s after reactor shutdown. The report contains a description of the experiment, the test conduct, test results, and results from the preliminary postirradiation examination. Calculations using a transient fuel rod behavior code are compared with the test results

    Although the scope of flight test engineering efforts may vary among organizations, all point to a common theme: flight test engineering is an interdisciplinary effort to test an asset in its operational flight environment. Upfront planning where design, implementation, and test efforts are clearly aligned with the flight test objective are keys to success. This chapter provides a top level perspective of flight test engineering for the non-expert. Additional research and reading on the topic is encouraged to develop a deeper understanding of specific considerations involved in each phase of flight test engineering.

    This software runs a suite of arbitrary software tests spanning various software languages and types of tests (unit level, system level, or file comparison tests). The dtest utility can be set to automate periodic testing of large suites of software, as well as running individual tests. It supports distributing multiple tests over multiple CPU cores, if available. The dtest tool is a utility program (written in Python) that scans through a directory (and its subdirectories) and finds all directories that match a certain pattern and then executes any tests in that directory as described in simple configuration files.

  9. Pancreatic exocrine function testing

    International Nuclear Information System (INIS)

    It is important to understand which pancreatic function tests are available and how to interpret them when evaluating patients with malabsorption. Available direct tests are the secretin stimulation test, the Lundh test meal, and measurement of serum or fecal enzymes. Indirect tests assess pancreatic exocrine function by measuring the effect of pancreatic secretion on various nutrients. These include triglycerides labeled with carbon 14, cobalamin labeled with cobalt 57 and cobalt 58, and para-aminobenzoic acid bound to a dipeptide. Of all these tests the secretin stimulation test is the most accurate and reliable if done by experienced personnel. However, the indirect tests are simpler to do and appear to be comparable to the secretin test at detecting pancreatic exocrine insufficiency. These indirect tests are becoming clinically available and clinicians should familiarize themselves with the strengths and weaknesses of each

  14. Irradiation Effects Test Series: Test IE-3. Test results report

    International Nuclear Information System (INIS)

    The objectives of the test reported were to: (a) determine the behavior of irradiated fuel rods subjected to a rapid power increase during which the possibility of a pellet-cladding mechanical interaction failure is enhanced and (b) determine the behavior of these fuel rods during film boiling following this rapid power increase. Test IE-3 used four 0.97-m long pressurized water reactor type fuel rods fabricated from previously irradiated fuel. The fuel rods were subjected to a preconditioning period, followed by a power ramp to 69 kW/m at a coolant mass flux of 4920 kg/s-m2. After a flow reduction to 2120 kg/s-m2, film boiling occurred on the fuel rods. One rod failed approximately 45 seconds after the reactor was shut down as a result of cladding embrittlement due to extensive cladding oxidation. Data are presented on the behavior of these irradiated fuel rods during steady-state operation, the power ramp, and film boiling operation. The effects of a power ramp and power ramp rates on pellet-cladding interaction are discussed. Test data are compared with FRAP-T3 computer model calculations and data from a previous Irradiation Effects test in which four irradiated fuel rods of a similar design were tested. Test IE-3 results indicate that the irradiated state of the fuel rods did not significantly affect fuel rod behavior during normal, abnormal (power ramp of 20 kW/m per minute), and accident (film boiling) conditions

O teste de vasorreatividade pulmonar é indicado para definir a melhor opção terapêutica. Muitas drogas têm sido utilizadas para a realização desse teste, sendo o óxido nítrico inalado a melhor opção, por apresentar ação específica pulmonar e meia vida muita curta (5-10 s. O resultado desse teste identifica candidatos à cirurgia cardíaca nas cardiopatias congênitas e candidatos ao uso de antagonista de cálcio nas outras formas de hipertensão pulmonar. A realização e interpretação do teste de vasorreatividade pulmonar exigem grande responsabilidade, e erros podem levar a decisões erradas e à ocorrência de óbitos.Pulmonary arterial hypertension is classified as idiopathic or secondary (associated with collagenoses, heart disease, portal hypertension, pulmonary thromboembolism, and pulmonary vascular diseases. Pulmonary vasoreactivity should be tested in order to define the best treatment option. Of the many drugs that have been used to test pulmonary vasoreactivity, inhaled nitric oxide is the best choice, due its specific pulmonary effect and very short half-life (5-10 s. The results of this test identify candidates for heart surgery among patients with congenital heart disease and candidates for the use of calcium antagonists among patients with other forms of pulmonary hypertension. Performing and interpreting the results of such tests are a great responsibility, since mistakes can lead to incorrect treatment decisions, resulting in the death of patients.

  18. Nondestructive testing of materials

    International Nuclear Information System (INIS)

    NUKEM has transferred know-how from reactor technology to materials testing. The high and to a large extent new quality standards in the nuclear industry necessitate reliable measuring and testing equipment of the highest precision. Many of the tasks presented to us could not be solved with the equipment available on the market, for which reason we have developed our own measuring, testing and control systems. We have therefore acquired considerable experience in dealing with specific measuring, testing and control tasks and can handle even out-of-the-way problems that are submitted to us from a wide variety of fields. Our mechanical systems for the checking of close-tolerance gaps, the automatic determination of pellet dimensions and the measurement of absolute lengths and absolute velocities are in use in many different industrial fields. We have succeeded in solving unusual testing and sorting problems with the aid of automated surface testing equipment working on optical principles. Our main activities in the field of non-destructive testing have been concentrated on ultrasonic and eddy current testing and, of late, acoustic emission analysis. NUKEM ultrasonic systems are notable for their high defect detection rate and testing accuracy, combined with high testing speed. The equipment we supply includes ultrasonic rotary systems for the production testing of quality tubes, ultrasonic immersion systems for the final testing of reactor cladding tubes, weld testing equipment, and test equipment for the bonds in multi-layer plates.

  19. Advanced test reactor. Testing capabilities and plans

    International Nuclear Information System (INIS)

    The Advanced Test Reactor (ATR), at the Idaho National Laboratory (INL), is one of the world's premier test reactors for providing the capability for studying the effects of intense neutron and gamma radiation on reactor materials and fuels. The physical configuration of the ATR, a 4-leaf clover shape, allows the reactor to be operated at different power levels in the corner 'lobes' to allow for different testing conditions for multiple simultaneous experiments. The combination of high flux (maximum thermal neutron fluxes of 1E15 neutrons per square centimeter per second and maximum fast [E>1.0 MeV] neutron fluxes of 5E14 neutrons per square centimeter per second) and large test volumes (up to 122 cm long and 12.7 cm diameter) provide unique testing opportunities. For future research, some ATR modifications and enhancements are currently planned. In 2007 the US Department of Energy designated the ATR as a National Scientific User Facility (NSUF) to facilitate greater access to the ATR for material testing research by a broader user community. This paper provides more details on some of the ATR capabilities, key design features, experiments, and plants for the NSUF. (author)

These rules have been applied with great success to the inprocess optical testing and final specification compliance testing of the JWST mirrors.

  4. Image processing for femoral endosteal anatomy detection: description and testing of a computed tomography based program

    International Nuclear Information System (INIS)

    A computed tomography (CT)-based image processing computer program was developed for three-dimensional (3D) femoral endosteal cavity shape modelling. For the examinations 50 cadaver femora were used. In the CT imaging 30 axial slices were taken above and below the lesser trochanter area from each femur. Different image analysis methods were used for femoral cavity detection depending on the structure of the processed slice. In the femoral shaft area simple thresholding methods succeeded, but in the problem areas of the metaphyseal femur edge, detection operators and local thresholding were required. In contour tracking several criteria were used to check the validity of the border pixels. The results were saved as four output data files: (i) a file for the longest anteroposterior (ap), ediolateral (ml) and oblique diameters computed by a Euclidian method, (ii) nd (iii) files for 2D and 3D data respectively, and (iv) a file for centre points of each slice. Finally, testing of the results and dimensions obtained from the image analysis were carried out manually by sawing the femora into 0 stipulated horizontal slices. The ap and ml dimensions were measured with caliper ruler. The CT-based image processing yielded a peak distribution of dimensions with a negative difference to those obtained in manual measurements. The mean difference between the image processing and the manual measurements was 1.1 mm (±0.7 mm, ±1 SD). The difference was highest in he proximal slices of the femora of group I (with lowest cortical thickness), i.e. 1.3 mm (±0.8 mm) and lowest in the distal slices of the femora from group III (with highest cortical thickness), i.e. 0.9 mm (±0.6 m). The results are acceptable for further use of the program to study endosteal anatomy for individual femoral component selection and designing asis. (author)

  5. Testing (HIV). Quick test receives Singapore approval.

    1996-04-22

    Hema-Strip HIV 1/2 is a rapid HIV antibody immunoassay developed by Saliva Diagnostic Systems, Inc. (SDS) which can be used by anyone who can read the product insert. The test kit is comprised of a small lancet for a finger stick, a cylindrical tube with a capillary tip and a SDS diagnostic strip inside, and a vial of buffer. Once blood is drawn by the lancet, the capillary tip is placed upon the blood droplet and the blood is automatically drawn into the tube. The tube is then inserted tip first into the vial of buffer. The buffer and blood migrate over the diagnostic strip inside, yielding stable results within 15 minutes. Studies have found Hema-Strip HIV 1/2 to have a sensitivity and specificity greater than 99.4%, as accurate as most conventional HIV tests which require the use of laboratory equipment and trained staff, and possibly hours to produce results. Moreover, the test kit requires neither refrigeration nor special storage. Hema-Strip HIV 1/2 has received a certificate of free sale from the Ministry of Health in Singapore and is now being submitted for regulatory approval in Brazil, China, Russia, India, Malaysia, Thailand, and the UK. SDS products in production include Sero-Strip HIV 1/2, a rapid serum-based HIV antibody test; Omni-SAL, a saliva collector which is the principal sample collection device used by British insurance companies for HIV testing with other confirmatory tests; Omni-Swab, a serrated swab which collects body fluids or cells; Saliva-Sampler, a saliva collection device used for general testing purposes; and Saliva Check, a test which checks the composition of saliva samples. SDS is in the final stages of developing Saliva-Strip HIV-1/2, a rapid saliva-based HIV antibody test. The company also intends to complete development in 1996 of a rapid blood-based antibody test for the Helicobacter pylori bacteria, a pathogen linked to 80% of peptic ulcers and gastric cancers.

  6. Gas Test Loop Booster Fuel Hydraulic Testing

    Energy Technology Data Exchange (ETDEWEB)

    Gas Test Loop Hydraulic Testing Staff

    2006-09-01

    The Gas Test Loop (GTL) project is for the design of an adaptation to the Advanced Test Reactor (ATR) to create a fast-flux test space where fuels and materials for advanced reactor concepts can undergo irradiation testing. Incident to that design, it was found necessary to make use of special booster fuel to enhance the neutron flux in the reactor lobe in which the Gas Test Loop will be installed. Because the booster fuel is of a different composition and configuration from standard ATR fuel, it is necessary to qualify the booster fuel for use in the ATR. Part of that qualification is the determination that required thermal hydraulic criteria will be met under routine operation and under selected accident scenarios. The Hydraulic Testing task in the GTL project facilitates that determination by measuring flow coefficients (pressure drops) over various regions of the booster fuel over a range of primary coolant flow rates. A high-fidelity model of the NW lobe of the ATR with associated flow baffle, in-pile-tube, and below-core flow channels was designed, constructed and located in the Idaho State University Thermal Fluids Laboratory. A circulation loop was designed and constructed by the university to provide reactor-relevant water flow rates to the test system. Models of the four booster fuel elements required for GTL operation were fabricated from aluminum (no uranium or means of heating) and placed in the flow channel. One of these was instrumented with Pitot tubes to measure flow velocities in the channels between the three booster fuel plates and between the innermost and outermost plates and the side walls of the flow annulus. Flow coefficients in the range of 4 to 6.5 were determined from the measurements made for the upper and middle parts of the booster fuel elements. The flow coefficient for the lower end of the booster fuel and the sub-core flow channel was lower at 2.3.

    Full Text Available It is essential to regularly test the usability of a learning management system, in order to ensure a fast adoption by new users and rapidly shift the focus from the platform to the content and the learning experience. Quantitative testing yields the most reliable results due to the large number of data points acquired, but lacks the in-depth analysis of the qualitative research from a controlled testing setup. We are proposing in this paper an integrated usability testing tool, which can replace a certain type of laboratory testing, where the users’ actions on the real platform are measured and analyzed. We conducted tests with the tool and compared the results with a small scale laboratory test using the same scenarios. The results seem to confirm the proposed tool as a viable alternative to the laboratory test.

    Department of Standard Malaysia (DSM) launched myPTP programme on 31 December 2013 in accordance to ISO/IC 17043. The standard states the requirements for Proficiency Testing. The provider of these services is called Proficiency Testing Provider (PTP). The role of PTP is to compare the proficiency level between inspection bodies or laboratories. With the assistance of expert panel, the PTP will determine the assigned value as reference to be compared to the values obtained from the inspection bodies or laboratories. Quality wise, this services is important as participation will improve wuality of the inspection quality continuously and increase confidence level of client and improve safety level. Requirement of PT in NDT is mentioned in SC1.5- Specific Criteria for Accreditation of Mechanical Testing and Non-Destructive Testing (NDT) for MS ISO/IEC17025 and MTR2- MIBAS Technical Requirements for Accreditation of NDT. This paper explains and discusses the result of this proficiency test done on a number of NDT companies that participated. (author)
