    We report experimental results obtained by using a wide-gap type emulsion chamber flown in the first Japanese-Russo joint balloon project, called RUNJOB ( RUssia- Nippon JOint Balloon-program). Two balloons were launched from Kamchatka in July 1995, and both were recovered successfully near the Volga River. The exposure time was 130 hours for the first flight and 168 hours for the second. The mean ceiling altitude, in both flights, was 32 km corresponding to 10 g/cm 2. Total area of the emulsion chamber was 0.8 m 2, and the thickness 0.385 and 2.28 collision m.f.p.'s for vertically incident proton- and iron-primaries, respectively. We detected 381 showers using Fuji-#200-type X-ray film; of these 174 showers were due to atmospheric secondary ?-rays, and the rest 207 came from nuclear components. The energy range covers 20˜200 TeV for proton-primary, 3˜30 TeV/nucleon for helium-primary, and 0.7˜5 TeV/nucleon for iron-primary. We give the energy spectra for various elements (proton, helium, …, iron) as well as the all-particle spectrum and the average mass of the cosmic-ray primaries.

    Single-particle inclusive experiments, and experiments that additionally measure a few correlations like the associated multiplicity, have provided the main contribution to our present understanding of high-energy heavy-ion collisions. The results from those experiments are in overall agreement with calculations of the cascade and hydrodynamical models. In the cascade model the collision of two nuclei is simulated as a cascade of nucleon-nucleon collisions using measured N-N cross sections. The hydrodynamical model, on the other hand, describes the nuclear collision as that of two fluids and makes use of a nuclear equation of state relating thermal and compressional energy densities to pressure. The pressure field dominates the expansion phase and leads to collective flow of the reaction products in a preferred direction. The observation of such effects in inclusive experiments is not well established. Collective effects that manifest themselves in the shape of the event in phase space are expected to be seen best in complete event detectors that measure the final state as exclusively as presently possible by measuring most of the charged particles emitted in the reaction. In addition, those detectors are well suited to test macroscopic concepts such as equilibrium and temperature. Global methods like the sphericity or thrust analysis take into account all the correlations measured in the event and are specially designed to determine the shape of an event in phase space and thus to define a reaction plane. Recent data from the Plastic Ball experiment about the study of nuclear stopping and thermalization and on global analysis are presented.

    Recent results of experimental work and theoretical modeling carried out in the TCABR tokamak are reported on characterization of MHD instabilities, improved diagnostics of rotation of the plasma column, excitation of Alven global modes, identification of GAMs, and the effect of rotation on their behavior. Detailed measurements of edge electrostatic perturbations and of magnetic island evolution and rotation indicate that the edge turbulence is substantially affected by the islands growth, leading to a strong modulation of the edge particle losses at the same frequency of the MHD activity. Measurements with spatial resolution also show that the growth of the MHD activity is due to nonlinear coupling of magnetic islands with different poloidal mode numbers, which increases the impurity influx. A new system of data acquisition and processing of the TCABR plasma rotation diagnostic was implemented. The system is based upon a single monochromator coupled with six photomultipliers tubes and allows one toroidal and two poloidal simultaneous rotation measurements. The excitation of Global Alfven Waves - GAW has been investigated, using a new type of radio frequency amplifier. The GAW resonances are searched either by a pre-programmed density variation, at fixed generator frequency, or through three RF frequency sweeps from 2 to 4.5 MHz, at stationary density. GAW resonances have been found and their somewhat new characteristics are presented. The investigation of the effect of poloidal and toroidal rotation on the characteristics of the geodesic acoustic mode has been investigated, both theoretically and experimentally. It is found that the assumption of isothermal flux surfaces gives rise to a third branch of this mode. Detailed predictions coupled with experimental measurements are currently being carried out to investigate this question.

    A compact integrated narcotics detection instrument (CINDI) has been developed at NOVA R&D, Inc. with funding provided by the U.S. Coast Guard. CINDI is designed as a portable sensitive neutron backscatter detector which has excellent penetration for thick and high Z compartment barriers. It also has a highly sensitive detection system for backscattered neutrons and, therefore, uses a very weak californium-252 neutron source. Neutrons backscatter profusely from materials that have a large hydrogen content, such as narcotics. The rate of backscattered neutrons detected is analyzed by a microprocessor and displayed on the control panel. The operator guides the detector along a suspected area and displays in real time the backscattered neutron rate. CINDI is capable of detecting narcotics effectively behind panels made of steel, wood, fiberglass, or even lead-lined materials. This makes it useful for inspecting marine vessels, ship bulkheads, automobiles, structure walls or small sealed containers. The strong response of CINDI to hydrogen-rich materials such as narcotics makes it an effective tool for detecting concealed drugs. Its response has been field tested by NOVA, the U.S. Coast Guard and Brewt Power Systems. The results of the tests show excellent response and specificity to narcotic drugs. Several large shipments of concealed drugs have been discovered during these trials and the results are presented and discussed.

    Susceptibility tests using 7 antimicrobial agents (carbenicillin, chloramphenicol, clindamycin, penicillin, cephalothin, metronidazole, and tetracycline) were run against 35 anaerobes including Bacteroides fragilis (17), other gram-negative bacilli (7), clostridia (5), peptococci (4), and eubacteria (2). Results in triplicate obtained by the microbroth dilution method and the aerobic modification of the broth disk method were compared with those obtained with an agar dilution method using Wilkins-Chalgren agar. Media used in the microbroth dilution method included Wilkins-Chalgren broth, brain heart infusion broth, brucella broth, tryptic soy broth, thioglycolate broth, and Schaedler's broth. A result differing by more than one dilution from the Wilkins-Chalgren agar result was considered a discrepancy, and when there was a change in susceptibility status this was termed a significant discrepancy. The microbroth dilution method using Wilkins-Chalgren broth and thioglycolate broth produced the fewest total discrepancies (22 and 24, respectively), and Wilkins-Chalgren broth, thioglycolate, and Schaedler's broth had the fewest significant discrepancies (6, 5, and 5, respectively). With the broth disk method, there were 15 significant discrepancies, although half of these were with tetracycline, which was the antimicrobial agent associated with the highest number of significant discrepancies (33), considering all of the test methods and media.

    The graded electrical breakdown (EBD) method was introduced to obtain ohmic contact on nonpolar (11\\bar{2}0) a-plane p-GaN surfaces. The graded EBD method, by which the electrical stress voltage could be increased up to 50 V in the Ni/SiO2/p-GaN structure, produced an ohmic contact with a specific resistance of 1.47 × 10?3 ? cm2 without any sudden degradation in the contact. Secondary ion mass spectroscopy measurements revealed that the ohmic contact was due to gallium vacancies generated near the SiO2/p-GaN interface. Current–voltage-temperature measurements exhibited an insensitive temperature dependence of the contact resistance, indicating predominant tunneling transport at the contact.

    Recently we have developed a lidar fluorescence sensor system, consisting of a compact Nd:YAG laser with second and third harmonics generation, mounted on a Newtonian receiver coupled to a small monochromator with a ICCD detection unit. The laser radiation induces fluorescence on a remote target and fluorescence spectra are recorded. Substances like DOM, chlorophyll and other plants pigments, algae and phytoplankton, crude oil, etc. can be identified in this way. Preliminary laboratory work was done on various substances. The concentration of the trace compound in water is usually obtained by normalizing the integrated fluorescence intensity respect to the Raman peak of water at 402 nm. Preliminary results of laboratory calibration measurements on water pollution and vegetation will be presented.

    GAME(GEWEX Asian Monsoon Experiment) selected one of their field experiment site in Siberia. Importance of this area was, first, its large area on Eurasia, second, potential effect of fresh water supply to the Arctic Ocean, thirdly, this region is one center of the recent intense warming. In order to progress the study, we set up the following objectives. 1) Clarify the physical processes of the land-surface/atmosphere interacting system. 2) Clarify the characteristics and variability of regional energy/water cycle. 3) Obtain the climate trend and land-surface change during the past 50 years. 4) Improve and develop atmospheric and hydrological models 5) Collection and archive of regional ground based/satellite data. 6) Establishment of observational network for long-term variation study, and development of hardware. The 1st phase of the study was 1996-2001, and from 2002 to 2004, 2nd phase emphasizing on integration is continued. Among the drainage in Siberia, Lena River was selected and following main results were obtained. (1) Land surface processes at three local sites: Heat water exchange study was made at three sites (Tundra: Tiksi, Flat taiga:Yakutsk, Mountaineous taiga:Tynda) for multiple years. They all showed strong influence of frozen ground (permafrost) to the heat/ water balance at patch scale. Snow cover had strong influence to hydrological process at Tundra and Mountaineous taiga, but it was masked at Flat Taiga. In Flat taiga, rhythm of heat flux to atmosphere is regulated strongly by foliation of leaves. Grassland (called alas) in comparison with nearby forest show different seasonal progress of fluxes, higher evaporation and low sensible heat at small young alas, and lower evaporation at vastly cultivated alas. Inter-annual variation of evaporation seem to be small in the Flat taiga forest compared with Tundra, although soil moisture show strong inter-annual variability, mainly due to the result of active function of the trees. In dry years trees used the soil moisture at deep depth. (2) Land/surface atmosphere interaction at flat taiga: According to the aircraft observation of heterogenous land surface at 100km scale including Lena River, distribution of low level heat/water fluxes (100m) show complex pattern influenced by characteristics of boundary layer and local circulation. (3) Precipitation recycling: Stable Isotope analysis show the seasonal change in the character of precipitation recycling, weaker in the early summer and stronger in late summer (August) in this area. (4) Hydrological models sensitivity tests: Hydrological models were developed applicable to the large drainage, and result showed that drainage is more sensitive to change in precipitation than to air temperature. (5) Development of automated year-round observation system: Automated observation system made success in acquiring year-round meteorological and ground surface data at the three local observation sites

    BACKGROUND: Experience with the use of porous high-density polyethylene (PHDPE) for reconstruction of the nasal framework has been limited. OBJECTIVE: To confirm the safety and utility of PHDPE by analyzing aesthetic outcomes and assessing the frequency of complication related to PHDPE in a large, population-based, long-term follow-up study. METHODS: A total of 151 patients who had undergone septoplasty and/or functional rhinoplasty using PHDPE were enrolled. PHDPE sheets were used for diverse purposes such as septal extension graft, spreader graft, columellar strut or dorsal augmentation graft. After a long-term follow-up period (mean [± SD] 39.5±27.8 months; range six to 101 months), postoperative aesthetic outcome was evaluated objectively (by independent surgeons) and subjectively (patient self-report). Complications related to PHDPE were estimated through review of medical records. RESULTS: The most common use of the PHDPE graft was for septal extension (n=80 [42.6%]) and spreader graft (n=58 [30.9%]). Results of aesthetic evaluation by surgeons were excellent in 61 cases (40.4%), good in 54 (35.8%) and fair in 34 (22.5%). According to patient self-report, 100 were ‘satisfied’ (66.2%) and 36 rated their new profile as ‘better than the preoperative profile’ (23.8%). Complications were reported in six cases (4.0% [five cases of extrusion and one case of infection]). All complications were resolved after the surgical removal of PHDPE sheets under local anesthesia. CONCLUSION: The present study demonstrated that PHDPE could be used in functional primary rhinoplasty with excellent long-term aesthetic results and safety. PMID:25152641

    The basic requirements for getting reliable Li-S battery data have been discussed in this work. Unlike Li-ion batteries, electrolyte-rich environment significantly affects the cycling stability of Li-S batteries prepared and tested under the same conditions. The reason has been assigned to the different concentrations of polysulfide-containing electrolytes in the cells, which have profound influences on both sulfur cathode and lithium anode. At optimized S/E ratio of 50 g L-1, a good balance among electrolyte viscosity, wetting ability, diffusion rate dissolved polysulfide and nucleation/growth of short-chain Li2S/Li2S2 has been built along with largely reduced contamination on the lithium anode side. Accordingly, good cyclability, high reversible capacity and Coulombic efficiency are achieved in Li-S cell with controlled S/E ratio without any additive. Other factors such as sulfur content in the composite and sulfur loading on the electrode also need careful concern in Li-S system in order to generate reproducible results and gauge the various methods used to improve Li-S battery technology.

    Paternity analysis using microsatellite information is a well-studied subject. These markers are ideal for parentage studies and fingerprinting, due to their high-discrimination power. This type of data is used to assign paternity, to compute the average selfing and outcrossing rates and to estimate the biparental inbreeding. There are several public domain programs that compute all this information from data. Most of the time, it is necessary to export data to some sort of format, feed it to the program and import the output to an Excel book for further processing. In this article we briefly describe a program referred from now on as Paternity Analysis in Excel (PAE), developed at IST and IBET (see the acknowledgments) that computes paternity candidates from data, and other information, from within Excel. In practice this means that the end user provides the data in an Excel sheet and, by pressing an appropriate button, obtains the results in another Excel sheet. For convenience PAE is divided into two modules. The first one is a filtering module that selects data from the sequencer and reorganizes it in a format appropriate to process paternity analysis, assuming certain conventions for the names of parents and offspring from the sequencer. The second module carries out the paternity analysis assuming that one parent is known. Both modules are written in Excel-VBA and can be obtained at the address (www.math.ist.utl.pt/~fmd/pa/pa.zip). They are free for non-commercial purposes and have been tested with different data and against different software (Cervus, FaMoz, and MLTR). PMID:17928093

    Purpose: To determine the effect of short hairpin ribonucleic acid (shRNA)-mediated suppression of thymidylate synthase (TS) on cytotoxicity and radiosensitization and the mechanism by which these events occur. Methods and Materials: shRNA suppression of TS was compared with 5-fluoro-2 Prime -deoxyuridine (FdUrd) inactivation of TS with or without ionizing radiation in HCT116 and HT29 colon cancer cells. Cytotoxicity and radiosensitization were measured by clonogenic assay. Cell cycle effects were measured by flow cytometry. The effects of FdUrd or shRNA suppression of TS on dNTP deoxynucleotide triphosphate imbalances and consequent nucleotide misincorporations into deoxyribonucleic acid (DNA) were analyzed by high-pressure liquid chromatography and as pSP189 plasmid mutations, respectively. Results: TS shRNA produced profound ({>=}90%) and prolonged ({>=}8 days) suppression of TS in HCT116 and HT29 cells, whereas FdUrd increased TS expression. TS shRNA also produced more specific and prolonged effects on dNTPs deoxynucleotide triphosphates compared with FdUrd. TS shRNA suppression allowed accumulation of cells in S-phase, although its effects were not as long-lasting as those of FdUrd. Both treatments resulted in phosphorylation of Chk1. TS shRNA alone was less cytotoxic than FdUrd but was equally effective as FdUrd in eliciting radiosensitization (radiation enhancement ratio: TS shRNA, 1.5-1.7; FdUrd, 1.4-1.6). TS shRNA and FdUrd produced a similar increase in the number and type of pSP189 mutations. Conclusions: TS shRNA produced less cytotoxicity than FdUrd but was equally effective at radiosensitizing tumor cells. Thus, the inhibitory effect of FdUrd on TS alone is sufficient to elicit radiosensitization with FdUrd, but it only partially explains FdUrd-mediated cytotoxicity and cell cycle inhibition. The increase in DNA mismatches after TS shRNA or FdUrd supports a causal and sufficient role for the depletion of dTTP thymidine triphosphate and consequent DNA mismatches underlying radiosensitization. Importantly, shRNA suppression of TS avoids FP-mediated TS elevation and its negative prognostic role. These studies support the further exploration of TS suppression as a novel radiosensitizing strategy.

    Studies have found associations between better outcomes and a variety of structural and process criteria that help explain the wide outcome variations that occur across hospitals. In response, Centers of Excellence programs have been developed by multiple third parties. Despite this, programs have yielded disappointing results and can have unintended consequences. To outweigh potential harms, outcomes at Centers of Excellence must be clearly superior. We need to change how hospitals are designated and provide evidence that Centers of Excellence are truly excellent. PMID:25565122

    Background and purpose The Lubinus SP II stem is well documented in both orthopedic registries and clinical studies. Worldwide, the most commonly used stem lengths are 150 mm and 170 mm. In 1995, the 130-mm stem was introduced, but no outcome data have been published. We assessed the long-term survival of the Lubinus SP II 130-mm stem in primary total hip arthroplasty. Patients and methods In a retrospective cohort study, we evaluated 829 patients with a Lubinus SP II primary total hip arthroplasty (932 hips). The hips were implanted between 1996 and 2001. The primary endpoint was revision for any reason. The mean follow-up period was 10 (5–15) years. Results Survival analysis showed an all-cause 10-year survival rate of the stem of 98.7% (95% CI: 99.7–97.7), and all-cause 10-year survival of the total hip arthroplasty was 98.3% (95% CI: 99.3–97.3). Interpretation Excellent long-term results can be achieved with the cemented Lubinus SP II with the relatively short 130-mm stem. This stem has potential advantages over its 150-mm and 170-mm siblings such as bone preservation distal to the stem, better proximal filling around the prosthesis, and easier removal. PMID:24694276

    We present the preliminary results of digital processing and segmentation of breast microcalcifications images. They were obtained using a Bede X ray tube with Cu anode, which was fixed at 20 kV and 1 mA. Different biopsies were scanned using a 128 Si microstrips detector. Total scanning resulted in a data matrix, which corresponded with the image of each biopsy. We manipulated the contrast of the images using histograms and filters in the frequency domain in Matlab. Then we intended to investigate about different contour models for the segmentation of microcalcifications boundaries, which were based on the contrast and shape of the image. These algorithms could be applied to mammographic images, which may be obtained by digital mammography or digitizing conventional mammograms.

    The 2013 Ultrasonic Testing (UT) modeling benchmark concerns direct echoes from side drilled holes (SDH), flat bottom holes (FBH) and corner echoes from backwall breaking artificial notches inspected with a matrix phased array probe. This communication presents the results obtained with the models implemented in the CIVA software: the pencilmodel is used to compute the field radiated by the probe, the Kirchhoff approximation is applied to predict the response of FBH and notches and the SOV (Separation Of Variables) model is used for the SDH responses. The comparison between simulated and experimental results are presented and discussed.

    Distributions of energy barriers in systems of magnetic nanoparticles have been calculated by means of the path integral method and the results have been compared with distributions previously obtained in our experiments by means of the temperature dependent magnetorelaxation method. The path integral method allowed to obtain energies of the interactions of magnetic moments of nanoparticles with axes of their easy magnetisation as well as energies of mutual interactions of magnetic moments. Calculated distributions of energy barriers have been described satisfactorily by curves of the lognormal distribution. We found an agreement between the theory and the experiment at temperatures above approximately 100 K. The influence of the volume concentration of nanoparticles and agglomeration on the energy barrier distribution has been investigated.

    The results of measurements performed during the year 2003 onboard aircraft, mostly during regular commercial flights of the Czech Airlines (CSA) are presented. The studies were performed during more than 30 individual flights, several dosemeters and equipments were used for both neutron and non-neutron components of the onboard radiation field. CSA colleagues submitted us for all flights with navigation data necessary for the calculation of onboard aircraft crew exposure with transport codes EPCARD and CARI. Direct readings of experimental equipments were corrected on the base of the calibration in CERN high-energy radiation fields. A reasonable agreement of measured and calculated data was observed. During one of the flights, a very deep Forbush decrease occurred. The experimental results confronted with calculation permitted to obtain new view on the influence of such events on aircraft crew exposure. PMID:16604652

    This paper reviews recent results in gamma-ray astronomy obtained from experiments flown on high-altitude balloons. New generation balloon-borne imaging experiments have produced the first gamma-ray maps of the Galactic center (GC) region. Balloon flights of new gamma-ray spectrometers with improved sensitivity have provided important new information on the GC annihilation line. For the first time, the narrow 511 keV line as been resolved (FWHM approx. = 3 keV). A very interesting spectral feature at approximately 170 keV has been attributed to backscattered annihilation, probably from the vicinity of a compact object. New results from the Compton Gamma-Ray Observatory (CGRO)/OSSE and Granat/SIGMA experiments on the annihilation line, when considered together with the recent balloon results, have added greatly to our knowledge and understanding of the origin and distribution of this emission. Balloon-borne instruments have made important measurements of gamma-ray continuum and line emission from SN 1987A. The GRIS spectrometer unambiguously resolved the 847 and 1238 keV line emission from radioactive Co-56 synthesized during the explosion. This data indicated that simple spherically symmetric and homogeneous models did not provide an adequate description of the expanding SN shell.

  11. Glucose Meters: A Review of Technical Challenges to Obtaining Accurate Results

    2009-01-01

    Glucose meters are universally utilized in the management of hypoglycemic and hyperglycemic disorders in a variety of healthcare settings. Establishing the accuracy of glucose meters, however, is challenging. Glucose meters can only analyze whole blood, and glucose is unstable in whole blood. Technical accuracy is defined as the closeness of agreement between a test result and the true value of that analyte. Truth for glucose is analysis by isotope dilution mass spectrometry, and frozen serum standards analyzed by this method are available from the National Institute of Standards and Technology. Truth for whole blood has not been established, and cells must be separated from the whole blood matrix before analysis by a method like isotope dilution mass spectrometry. Serum cannot be analyzed by glucose meters, and isotope dilution mass spectrometry is not commonly available in most hospitals and diabetes clinics to evaluate glucose meter accuracy. Consensus standards recommend comparing whole blood analysis on a glucose meter against plasma/serum centrifuged from a capillary specimen and analyzed by a clinical laboratory comparative method. Yet capillary samples may not provide sufficient volume to test by both methods, and venous samples may be used as an alternative when differences between venous and capillary blood are considered. There are thus multiple complexities involved in defining technical accuracy and no clear consensus among standards agencies and professional societies on accuracy criteria. Clinicians, however, are more concerned with clinical agreement of the glucose meter with a serum/plasma laboratory result. Acceptance criteria for clinical agreement vary across the range of glucose concentrations and depend on how the result will be used in screening or management of the patient. A variety of factors can affect glucose meter results, including operator technique, environmental exposure, and patient factors, such as medication, oxygen therapy, anemia, hypotension, and other disease states. This article reviews the challenges involved in obtaining accurate glucose meter results. PMID:20144348

    The LIULIN-3M instrument is a further development of the LIULIN dosimeter-radiometer, which has been used on the NffR space station in the 1988-1994 time period, The LIULIN-3M is designed for continuous monitoring of the radiation environment during the BION-12 satellite flight in 1999. A semiconductor detector with 1 mm thickness and 1 cm(exp 2) area is used in the instrument. Pulse high analysis technique is used for measurement of the energy losses in the detector. The final data sets from the instrument are the flux and the dose rate for the exposition time and 256 channels of LET spectra if a non-nal coincidence of the particles to the detector is considered. The LIULIN-3M instrument was calibrated by proton fluxes with different energies at the Indiana University Cyclotron Facility in June 1997 and was used for space radiation measurements during commercial aircraft flights. Obtained calibration and flight results are analyzed in the paper.

  15. Some results obtained with laser Doppler and laser two focus anemometers in transonic steam flows

    NASA Astrophysics Data System (ADS)

    Decuypere, R.

    A laser Doppler (LDA) and two types of laser transit velocimeters (LTV) have been used in steam. The facility comprises a two-dimensional tunnel and a small instructional turbine. For the LTVs only the backscatter alignment is applied, while both forward and backscatter configurations are examined for the LDA. In contrast to the LTV, the laser Doppler system requires seeding. A pneumatic atomizer produces water droplets upstream of the measuring station. A computer program accounts for droplet evaporation. This allows the ideal initial droplet diameter to be calculated. Using a particle-sizer the optimum atomizer is selected. It is explained how signals produced by big droplets are rejected. This is significantly simplified when the Doppler processor is interfaced with a multichannel analyzer. A comparison is made between the velocity distributions in a transonic steam turbine cascade obtained by the LDA processor and the LTVs where the signals are processed with either a multichannel analyzer or a correlator.

  17. A method for obtaining practical flutter-suppression control laws using results of optimal control theory

    Newson, J. R.

    1979-01-01

    The results of optimal control theory are used to synthesize a feedback filter. The feedback filter is used to force the output of the filtered frequency response to match that of a desired optimal frequency response over a finite frequency range. This matching is accomplished by employing a nonlinear programing algorithm to search for the coefficients of the feedback filter that minimize the error between the optimal frequency response and the filtered frequency response. The method is applied to the synthesis of an active flutter-suppression control law for an aeroelastic wind-tunnel model. It is shown that the resulting control law suppresses flutter over a wide range of subsonic Mach numbers. This is a promising method for synthesizing practical control laws using the results of optimal control theory.

The observations were carried out using the 50-cm telescope of the Teramo Astronomical Observatory (TAO) and the 91-cm telescope of the Catania Astronomical Observatory during the 1983-1984 oppositions. The reduced data indicate the following main belt asteroids: 11 Partenope; 129 Antigone; and 20 Massalia. The asteroids 41 Daphne, 344 Desiderata, and 31 Euphrosyne were also identified. The rotation period of 11 Partenope was P = 7.83 hours, and that of 34 Desiderata P = 10,53 hours. The shape and the pole coordinates of 20 Massalia, 31 Euphrosyne, and 29 Antigone were derived, and those of 41 Daphne were confirmed. The lightcurves of the remaining asteroids are given, and some of their rotational properties and morphological features are discussed.

    Much progress in realistic modeling of core-collapse supernovae has occurred recently through the availability of multi-teraflop machines and the increasing sophistication of supernova codes. These improvements are enabling simulations with enough realism that the explosion mechanism, long a mystery, may soon be delineated. We briefly describe the CHIMERA code, a supernova code we have developed to simulate core-collapse supernovae in 1, 2, and 3 spatial dimensions. We then describe the results of an ongoing suite of 2D simulations initiated from a 12, 15, 20, and 25 solar mass progenitor. These have all exhibited explosions and are currently in the expanding phase with the shock at between 5,000 and 20,000 km. We also briefly describe an ongoing simulation in 3 spatial dimensions initiated from the 15 solar mass progenitor.

    Nuclear heating inside an MTR reactor has to be known in order to be able to control samples temperature during irradiation experiments. An R and D program has been carried out at CEA to design a new type of in-core calorimetric system. This new development, started in 2002, has for main objective to manufacture a calorimeter suitable to monitoring nuclear heating inside the 70 MWth OSIRIS material testing reactor operated by CEA's Nuclear Energy Division at the Saclay research center. An innovative calorimetric probe, associated to a specific handling system, has been designed to provide access to measurements both along the fissile height and on the upper part of the core, where nuclear heating still remains high. Two mock-ups of the probe were manufactured and tested in 2005 and 2009 in ex-core area of OSIRIS reactor for process validation, while a displacement system has been especially studied to move the probe along a given axial measurement range. This paper deals with the development, tests on preliminary mock-ups and the finalization of the probe. Main modeling and experimental results are presented. Moreover, alternative methods to calibration for nuclear heating rate measurements which are now possible with this new calorimeter are presented and discussed. (authors)

    Purpose To analyze the complications and costs of minilaparotomies performed by a nephrologist (group A) compared with conventional laparotomies performed by a surgeon (group B) for peritoneal catheter implantation. Setting Two university hospitals (Santa Sofia and Caldas) in Manizales, Caldas, Colombia. Methods The study included stage 5 chronic kidney disease patients, with indication of renal replacement therapy, who were candidates for peritoneal dialysis and gave informed consent for a peritoneal catheter implant. Minilaparotomies were performed by a nephrologist in a minor surgery room under local anesthesia. Conventional laparotomies were performed by a surgeon in an operating room under general anesthesia. Results Two nephrologists inserted 157 peritoneal catheters, and seven general surgeons inserted 185 peritoneal catheters. The groups had similar characteristics: the mean age was 55 years, 49.5% were men, and the primary diagnoses were diabetic nephropathy, hypertensive nephropathy, and unknown etiology. The implant was successful for 98.09% of group A and 99.46% of group B. There was no procedure-related mortality. The most frequent complications in the first 30 days postsurgery in group A versus group B, respectively, were: peritonitis (6.37% versus 3.78%), exit-site infection (3.82% versus 2.16%), tunnel infection (0% versus 0.54%), catheter entrapment by omentum (1.27% versus 3.24%), peritoneal effluent spillover (1.91% versus 2.16%), draining failure (4.46% versus 6.49%), hematoma (0% versus 1.08%), catheter migration with kinking (3.18% versus 2.70%), hemoperitoneum (1.27% versus 0%), and hollow viscera accidental puncture (1.91% versus 0.54%). There were no statistically significant differences in the number of complications between groups. In 2013, the cost of a surgeon-implanted peritoneal dialysis catheter in Colombia was US $366 (666,000 COP), whereas the cost of a nephrologist-implanted catheter was US $198 (356,725 COP). Conclusion Nephrologist-performed minilaparotomies had similar effectiveness to surgeon-performed conventional laparotomies and were cost-effective; however, the nonuse of general anesthesia may be related with hollow viscera puncture during the procedure.

    ISAC is an ultra-high-vacuum (UHV) setup, with a base pressure down to P = 2.5 ?ó 10-11 mbar, dedicated to the study of ice processes. The UHV conditions of ISAC allow experiments under extremely clean conditions. Transmittance FTIR spectroscopy coupled to QMS proved to be ideal for in situ monitoring of ice processes that include radiation and thermal annealing. The optimal performance of ISAC becomes evident after an analysis of the results. As an example, thermal desorption of CO starting at 15 K, induced by the release of H2 from the CO ice, was observed. We measured the photodesorption yield of CO ice per incident photon at 7, 8, and 15 K, respectively yielding 6.4 ± 0.5 10-2} 5.4± 0.5 10-2, and 3.5± 0.5 10-2 CO molecules photon (7.3-10.5 eV)-1. Our value of the photodesorption yield of CO ice at 15 K is about one order of magnitude higher than the previous estimate. We confirmed that the photodesorption yield is constant during irradiation and independent of the ice thickness. Only below ˜ 5 monolayers ice thickness the photodesorption rate decreases, which suggests that only the UV photons absorbed in the top 5 monolayers led to photodesorption. The measured CO photodesorption quantum yield at 7 K per absorbed photon in the top 5 monolayers is 3.4 molecules photon-1. We also studied the UV-photochemistry of H2S ice, leading to the formation of more refractory products such as H2S2, S2, and S8. X-ray irradiation experiments of ice were also performed with ISAC. These experiments are challenging because the flux of current X-ray sources emitting in the 0.1-1 keV range is very low, and therefore the product abundances are at the trace level. In our experiments, the typical irradiation dose was of 10-5 - 10-6 photons molecule-1. Despite that, we were able to detect for the first time X-ray irradiation products of several ices of astrophysical interest.

  13. A comparison of results obtained by two different chromium-51 methods of determining platelet survival and recovery

    1990-06-01

    A number of different methods exist that use chromium-51 to determine platelet survival and recovery. A 1986 article in TRANSFUSION described the recommended methods for conducting such studies in the hope of standardizing methodology and permitting interlaboratory comparison of results. The results obtained with the recommended method have been compared with those of our previous method. With the new method, recovery of fresh random-donor platelets prepared in polyolefin bags was 76 +/- 6 percent with a survival of 9.3 +/- 2.8 days (n = 4). After 5 days of storage, these values were 67 +/- 8 percent and 7.8 +/- 1.9 days. Similar values were obtained for fresh and stored platelets collected on automated cell separators. However, when our previous (pre-1986) method of evaluation was used, recovery of fresh platelets in the polyolefin bags was 56 +/- 11 percent, and survival was 8.6 +/- 1.3 days. The 5-day values were 36 +/- 5 percent and 6.9 +/- 2.7 days. These values are significantly lower (p less than 0.05) than those obtained with the newer method, but they are in agreement with those previously reported for other techniques. Thus, the new method consistently gives higher values, possibly as a result of a less harmful labeling procedure.

    FADES-CORE and TOUGHREACT are codes used to model the non-isothermal multiphase flow with multicomponent reactive transport in porous media. Different flow and reactive transport problems were used to compare the FADES-CORE and TOUGHREACT codes. These problems take into account the different cases of multiphase flow with and without heat transport, conservative transport, and reactive transport. Consistent results were obtained from both codes, which use different numerical methods to solve the differential equations resulting from the various physicochemical processes. Here we present the results obtained from both codes for various cases. Some results are slightly different with minor discrepancies, which have been remedied, so that both codes would be able to reproduce the same processes using the same parameters. One of the discrepancies found is related to the different calculation for thermal conductivity in heat transport, which affects the calculation of the temperatures, as well as the pH of the reaction of calcite dissolution problem modeled. Therefore it is possible to affirm that the pH is highly sensitive to temperature. Generally speaking, the comparison was concluded to be highly satisfactory, leading to the complete verification of the FADES-CORE code. However, we must keep in mind that, as there are no analytical solutions available with which to verify the codes, the TOUGHREACT code has been thoroughly corroborated, given that the only possible way to prove that the code simulation is correct, is by comparing the results obtained with both codes for the identical problems, or to validate the simulation results with actual measured data.

    The LANDSAT system, operated in the country by CNPg/INPE since 1973, systematically acquires, produces, and distributes both multispectral and panchromatic images obtained through remote sensing satellites to thousands of researchers and technicians involved in the natural resources survey. To cooperate in the solution of national problems, CNPq/INPE is developing efforts in the area of manipulation of those images with the objective of making them useful as planimetric bases for the simple revision of already published maps or for its utilization as basic material in regions not yet reliability mapped. The results obtained from performed tests are presented and the existing limitations are discussed. The new system purchased to handle data from the next series of LANDSAT as well as from MAPSAT and SPOT which will be in operation within the 80's decade, and are designed not only for natural resources survey but also for the solution of cartographic problems.

  16. Quantitative assessment of the impact of biomedical image acquisition on the results obtained from image analysis and processing

    2014-01-01

    Introduction Dedicated, automatic algorithms for image analysis and processing are becoming more and more common in medical diagnosis. When creating dedicated algorithms, many factors must be taken into consideration. They are associated with selecting the appropriate algorithm parameters and taking into account the impact of data acquisition on the results obtained. An important feature of algorithms is the possibility of their use in other medical units by other operators. This problem, namely operator’s (acquisition) impact on the results obtained from image analysis and processing, has been shown on a few examples. Material and method The analysed images were obtained from a variety of medical devices such as thermal imaging, tomography devices and those working in visible light. The objects of imaging were cellular elements, the anterior segment and fundus of the eye, postural defects and others. In total, almost 200'000 images coming from 8 different medical units were analysed. All image analysis algorithms were implemented in C and Matlab. Results For various algorithms and methods of medical imaging, the impact of image acquisition on the results obtained is different. There are different levels of algorithm sensitivity to changes in the parameters, for example: (1) for microscope settings and the brightness assessment of cellular elements there is a difference of 8%; (2) for the thyroid ultrasound images there is a difference in marking the thyroid lobe area which results in a brightness assessment difference of 2%. The method of image acquisition in image analysis and processing also affects: (3) the accuracy of determining the temperature in the characteristic areas on the patient’s back for the thermal method - error of 31%; (4) the accuracy of finding characteristic points in photogrammetric images when evaluating postural defects – error of 11%; (5) the accuracy of performing ablative and non-ablative treatments in cosmetology - error of 18% for the nose, 10% for the cheeks, and 7% for the forehead. Similarly, when: (7) measuring the anterior eye chamber – there is an error of 20%; (8) measuring the tooth enamel thickness - error of 15%; (9) evaluating the mechanical properties of the cornea during pressure measurement - error of 47%. Conclusions The paper presents vital, selected issues occurring when assessing the accuracy of designed automatic algorithms for image analysis and processing in bioengineering. The impact of acquisition of images on the problems arising in their analysis has been shown on selected examples. It has also been indicated to which elements of image analysis and processing special attention should be paid in their design. PMID:24997012

  17. Excellent local control with IOERT and postoperative EBRT in high grade extremity sarcoma: results from a subgroup analysis of a prospective trial

    2014-01-01

    Background To report the results of a subgroup analysis of a prospective phase II trial focussing on radiation therapy and outcome in patients with extremity soft tissue sarcomas (STS). Methods Between 2005 and 2010, 50 patients (pts) with high risk STS (size???5 cm, deep/extracompartimental location, grade II-III (FNCLCC)) were enrolled. The protocol comprised 4 cycles of neoadjuvant chemotherapy with EIA (etoposide, ifosfamide and doxorubicin), definitive surgery with IOERT, postoperative EBRT and 4 adjuvant cycles of EIA. 34 pts, who suffered from extremity tumors and received radiation therapy after limb-sparing surgery, formed the basis of this subgroup analysis. Results Median follow-up from inclusion was 48 months in survivors. Margin status was R0 in 30 pts (88%) and R1 in 4 pts (12%). IOERT was performed as planned in 31 pts (91%) with a median dose of 15 Gy, a median electron energy of 6 MeV and a median cone size of 9 cm. All patients received postoperative EBRT with a median dose of 46 Gy after IOERT or 60 Gy without IOERT. Median time from surgery to EBRT and median EBRT duration was 36 days, respectively. One patient developed a local recurrence while 11 patients showed nodal or distant failures. The estimated 5-year rates of local control, distant control and overall survival were 97%, 66% and 79%, respectively. Postoperative wound complications were found in 7 pts (20%), resulting in delayed EBRT (>60 day interval) in 3 pts. Acute radiation toxicity mainly consisted of radiation dermatitis (grade II: 24%, no grade III reactions). 4 pts developed grade I/II radiation recall dermatitis during adjuvant chemotherapy, which resolved during the following cycles. Severe late toxicity was observed in 6 pts (18%). Long-term limb preservation was achieved in 32 pts (94%) with good functional outcome in 81%. Conclusion Multimodal therapy including IOERT and postoperative EBRT resulted in excellent local control and good overall survival in patients with high risk STS of the extremities with acceptable acute and late radiation side effects. Limb preservation with good functional outcome was achieved in the majority of patients. Trial registration ClinicalTrials.gov NCT01382030, EudraCT 2004-002501-72, 17.06.2011 PMID:24885755

    Background The purpose of the present study was to compare the clinical results of 3 posterior cruciate ligament reconstruction techniques according to the time from injury to surgery and remnant PCL status and to evaluate the efficiency of each technique. Methods The records of 89 patients who underwent primary PCL reconstructions with a posterolateral corner sling were analyzed retrospectively. Thirty-four patients were treated by anterolateral bundle (ALB) reconstruction with preservation of the remnant PCL using a transtibial tunnel technique in the acute and subacute stages of injury (group 1). Forty patients were treated with remnant PCL tensioning and an ALB reconstruction using the modified inlay technique in the chronic stage (group 2), and fifteen patients were treated with double-bundle reconstruction using the modified inlay technique (group 3). The double-bundle reconstruction was performed if there was a very weak or no PCL remnant. Results The mean side-to-side differences in posterior tibial translation on the stress radiographs were reduced from 10.1 ± 2.5 mm in group 1, 10.6 ± 2.4 mm in group 2, and 12.8 ± 3.2 mm in group 3 preoperatively to 2.3 ± 1.4 mm in group 1, 2.3 ± 1.5 mm in group 2, and 4.0 ± 2.5 mm in group 3 at the last follow-up (p < 0.001, p < 0.001, and p < 0.001, respectively). Statistical analyses revealed that group 1 and group 2 were similar in terms of side-to-side difference changes in posterior tibial translation on the stress radiographs; however, group 3 was inferior to group 1 and group 2 at the last follow-up (p = 0.022). The clinical results were not significantly different among the three groups. Conclusions Excellent posterior stability and good clinical results were achieved with ALB reconstruction preserving the injured remnant PCL in the acute and subacute stages and remnant PCL tensioning with ALB reconstruction in the chronic stage. The PCL injuries could be surgically corrected with different techniques depending on both the remnant PCL status and the interval between the knee trauma and operation. PMID:24340147

    2009-09-01

    The Socorro code has been used to obtain density-functional theory results for the Ga vacancy (V{sub Ga}) and the As vacancy (V{sub As}) in GaAs. Calculations were performed in a nominal 216-atom simulation cell using the local-density approximation for exchange and correlation. The results from these calculations include: (1) the charge states, the atomic configurations of stable and metastable states, (2) energy levels in the gap, and (3) activation energies for migration. Seven charge states were found for the Ga vacancy (-3, -2, -1, 0, +1, +2, +3). The stable structures of the -3, -2, -1, and 0 charge states consist of an empty Ga site with four As neighbors displaying T{sub d} symmetry. The stable structures of the +1, +2, and +3 charge states consist of an As antisite next to an As vacancy; AsGa-V{sub As}. Five charge states were found for the As vacancy (-3, -2, -1, 0, +1). The stable structures of the -1, 0, and +1 charge states consist of an empty As site with four Ga neighbors displaying C{sub 2v} symmetry. The stable structures of the -3 and -2 charge states consist of a Ga antisite next to a Ga vacancy; Ga{sub As}-V{sub Ga}. The energy levels of V{sub Ga} lie below mid-gap while the energy levels of As{sub Ga}-V{sub As} lie above and below mid-gap. All but one of the V{sub As} energy levels lie above mid-gap while the As{sub Ga}-V{sub As} energy level lies below mid-gap. The migration activation energies of the defect states were all found to be larger than 1.35 eV.

    Here we present microwave palaeointensity results from 89 sister samples from the study of Zhu et al. [Zhu, R., Pan, Y., He, H., Qin, H., Ren, S., 2008. Palaeomagnetism and 40Ar/ 39Ar age from a Cretaceous volcanic sequence, Inner Mongolia, China: implications for the field variation during the Cretaceous normal superchron. Phys. Earth Planet. Int., 169, 59-75] who carried out Thellier palaeointensity analysis as part of their integrated palaeomagnetic and 40Ar/ 39Ar dating study of Cretaceous lava from the Suhungtu section, Inner Mongolia, China. Additionally, a comprehensive rock magnetic investigation has been carried out in order to determine the mineralogy and hence the validity of assuming that the remanence is a thermal remanent magnetisation (TRM). The microwave results are of apparent high quality and give flow mean palaeointensity estimates ranging from 13 to 49 ?T corresponding to virtual dipole moment (VDM) estimates ranging from 2.5 to 8.9 × 10 22 Am 2, and an overall mean VDM of 5.5 ± 1.9 × 10 22 Am 2 for the 24 flows (aged 110.6 ± 0.1 Ma). When the microwave results (using the perpendicular applied field method with partial microwave thermal remanence (pT MRM) and pT MRM tail checks) are compared to those obtained with the Thellier method (Coe version with pTRM but not tail checks, and heating in argon atmosphere) differences are seen at the sample, flow and palaeomagnetic unit level however, the overall means and spread in palaeointensity estimates are consistent. Some discrepancy is due to the differing sized sample sets and sample inhomogeneity but discrepancy is also interpreted to be due to the differing protocols, methodology, plus the subjectivity in interpretation. Considering only those results that are consistent to within 20% the spread in palaeointensity estimates remains. There is substantial rock magnetic evidence from progressive heating in air and argon experiments (both showing irreversible thermomagnetic behaviour) as well as looking at samples under the scanning electron microscope to suggest that maghaemite is present (albeit to varying degrees) in many of the samples. Alteration therefore occurred in nature and it is likely that the remanence will have been affected to differing degrees potentially causing underestimates in palaeointensity. Maghaemite is interpreted to be a remanence carrier where a component of remanence remains after heating to 580 °C and loss of pTRM acquisition capacity is found on heating. No correlation was found between the estimated palaeointensity (microwave or Thellier datasets) and amount of high temperature remanence or any rock magnetic parameter. This could suggest that the palaeointensity estimates are reliable or as seems likely more than one factor (such as methodology, protocol, interpretation, chemical remanent magnetisation (CRM) contamination and the geomagnetic field) are influencing the palaeointensity estimates. In an attempt to remove the influence of palaeointensity protocol and methodology the palaeointensity datasets were reduced to consist only of those results mutually consistent to 20% ( N = 22). No obvious correlation was again seen between the inferred maghaemite contribution and palaeointensity estimate. There is therefore no clear evidence for the biasing of results due to CRM contamination (assuming a simple relationship between biasing and maghaemite contribution) and it can thus be inferred that the geomagnetic field was a major influencing factor. Further studies are however needed to fully elucidate the extent and result of each possible influencing factor and ultimately the reliability of palaeointensity estimates from rocks of this type.

  7. Kinetic parameters of interstellar neutral helium. Review of results obtained during one solar cycle with the Ulysses/GAS-instrument

    NASA Astrophysics Data System (ADS)

    Witte, M.

    2004-11-01

    The GAS-instrument onboard the space probe Ulysses is designed to measure the local angular distribution of the flow of interstellar neutral He-atoms within ?3 AU distance from the sun. It allows to infer the kinetic parameters (velocity vector, temperature and density) of these particles outside the heliosphere (``at infinity''). During three observational periods, 1990/1991, shortly after launch and during the two fast latitude scans of Ulysses, from 9/1994 to 8/1996 and from 9/2000 to 8/2002, more than 300 measurements of the distributions were obtained and analyzed in detail. Known issues that relate to the pointing accuracy of the detector and to the efficiency calibration along with their impact on the results are addressed in this paper. The average values, derived from these observations and their refined analysis, are the bulk speed (vHe?= 26.3 ± 0.4 km s-1), the flow direction (ecliptic longitude ?? = 74.7° ± 0.5°, ecliptic latitude ?? = -5.2° ± 0.2°) and temperature (THe? = 6300 K ± 340 K). From 1990 to 2002, covering a complete solar cycle, no significant temporal variations of these parameters were observed, nor variations with solar latitude. In contrast, in the density nHe?, derived from the series of local observations along the Ulysses-orbit, substantial apparent variations were seen. After a first attempt to explain these by an inadequate energy calibration of the efficiency they are now interpreted as variations in the loss processes (predominantly photo-ionization), which the neutral gas experiences along its trajectory to the observer. While the temporal variations of the ionization rate were taken into account using the measured solar EUV irradiance (from CELIAS/SEM on SOHO), the residual latitudinal variation has been attributed to a dependence of the solar irradiance on latitude, which thus far has not been accessible to direct observations. As a result of a simple model that includes these effects a density nHe?= 0.015 ± 0.003 cm-3 has been deduced, which is in good agreement with an independent result from pickup ion observations.

    The Waste Isolation Pilot Plant (WPP) is located in southeastern New Mexico and is being developed by the U.S. Department of Energy (DOE) for the geologic (deep underground) disposal of transuranic (TRU) waste. A detailed performance assessment (PA) for the WIPP was carried out in 1996 and supports an application by the DOE to the U.S. Environmental Protection Agency (EPA) for the certification of the WIPP for the disposal of TRU waste. The 1996 WIPP PA uses a computational structure that maintains a separation between stochastic (i.e., aleatory) and subjective (i.e., epistemic) uncertainty, with stochastic uncertainty arising from the many possible disruptions that could occur over the 10,000 yr regulatory period that applies to the WIPP and subjective uncertainty arising from the imprecision with which many of the quantities required in the PA are known. Important parts of this structure are (1) the use of Latin hypercube sampling to incorporate the effects of subjective uncertainty, (2) the use of Monte Carlo (i.e., random) sampling to incorporate the effects of stochastic uncertainty, and (3) the efficient use of the necessarily limited number of mechanistic calculations that can be performed to support the analysis. The use of Latin hypercube sampling generates a mapping from imprecisely known analysis inputs to analysis outcomes of interest that provides both a display of the uncertainty in analysis outcomes (i.e., uncertainty analysis) and a basis for investigating the effects of individual inputs on these outcomes (i.e., sensitivity analysis). The sensitivity analysis procedures used in the PA include examination of scatterplots, stepwise regression analysis, and partial correlation analysis. Uncertainty and sensitivity analysis results obtained as part of the 1996 WIPP PA are presented and discussed. Specific topics considered include two phase flow in the vicinity of the repository, radionuclide release from the repository, fluid flow and radionuclide transport in formations overlying the repository, and complementary cumulative distribution functions used in comparisons with regulatory standards (i.e., 40 CFR 191, Subpart B).

    The inspiration for this Contract Report (CR) originated in discussions with the director of Marshall Space Flight Center (MSFC) Engineering who asked that we investigate the question: "How do you achieve excellence in aerospace engineering?" Engineering a space system is a complex activity. Avoiding its inherent potential pitfalls and achieving a successful product is a challenge. This CR presents one approach to answering the question of how to achieve Engineering Excellence. We first investigated the root causes of NASA major failures as a basis for developing a proposed answer to the question of Excellence. The following discussions integrate a triad of Technical Understanding and Execution, Partnership with the Project, and Individual and Organizational Culture. The thesis is that you must focus on the whole process and its underlying culture, not just on the technical aspects. In addition to the engineering process, emphasis is given to the need and characteristics of a Learning Organization as a mechanism for changing the culture.

    A spatially varying mean magnetic field gives rise to so-called adiabatic focusing of energetic particles propagating through the universe. In the past, different analytical approaches have been proposed to calculate the particle diffusion coefficient along the mean field with focusing. In the present paper, we show how these different results are related to each other. New results for the parallel diffusion coefficient that are more general than previous results are also presented.

    An ink dating method based on solvent analysis was recently developed using thermal desorption followed by gas chromatography/mass spectrometry (GC/MS) and is currently implemented in several forensic laboratories. The main aims of this work were to implement this method in a new laboratory to evaluate whether results were comparable at three levels: (i) validation criteria, (ii) aging curves, and (iii) results interpretation. While the results were indeed comparable in terms of validation, the method proved to be very sensitive to maintenances. Moreover, the aging curves were influenced by ink composition, as well as storage conditions (particularly when the samples were not stored in "normal" room conditions). Finally, as current interpretation models showed limitations, an alternative model based on slope calculation was proposed. However, in the future, a probabilistic approach may represent a better solution to deal with ink sample inhomogeneity. PMID:25389038

    The four HEU, intermediate-spectrum, copper-reflected Zeus experiments have shown discrepant results between measurement and calculation for the last several major releases of the ENDF library. The four benchmarks show a trend in reported C/E values with increasing energy of average lethargy causing fission. Recently, ORNL has made improvements to the evaluations of three key isotopes involved in the benchmark cases in question. Namely, an updated evaluation for 235U and evaluations of 63,65Cu. This paper presents the benchmarking results of the four intermediate-spectrum Zeus cases using the three updated evaluations.

    The anterior cruciate ligaments in 17 knees of 12 mongrel dogs were replaced with one of three porous minimally reactive prosthetic (synthetic) materials. The results show that while the porous materials support the ingrowth of fibrous tissue from the bone of the dog's knee, fatigue failure occurred before sufficient fibrous tissue was incorporated to reconstitute a functional ligament.

    A 30 MHz radar has recently been established at Gadanki (13.5°N, 79.2°E; 6.5°N magnetic latitude) to make unattended observations of the ionospheric field-aligned irregularities (FAI). This radar, called the Gadanki Ionospheric Radar Interferometer (GIRI), has been designed to have scanning capability of 100° in the east-west plane perpendicular to Earth's magnetic field and interferometry/imaging system to study drifts and spatial distribution of plasma irregularities at both large and small scales. In this paper, we present the first results on the E and F region FAI made using the scanning capability of the GIRI. Daytime observations of E region FAI show type 2 echoes with velocities predominantly upward northward (downward-southward) at altitudes >100 km (<100 km) and westward (eastward) in the forenoon (afternoon) with signature of tidal wind field. F region irregularities show bottom-type, bottomside and plume structures with close resemblance to those observed over the magnetic equator. Observations made with the east-west scanning capability have been used to study the origin, evolution, and drift of the FAI for the first time from Gadanki. Eastward drifts are estimated to be 90-210 m s-1 during 20-24 LT. Upward velocity as large as 500 m s-1 has been observed in the initial phase of the plume structures. Intriguingly, downward velocity as large as 60 m s-1 has also been observed in the plumes, displaying descending pattern, observed in the early evening hours. These results are presented and discussed in the light of current understanding of low-latitude plasma irregularities, and future prospects of GIRI are outlined.

    Recent GPS and rapture process studies for large earthquakes suggest that earthquake generation is controlled by the distribution of asperities. Among the subduction zones around the Japanese islands, the subduction zone along the Japan Trench is one of the well studied areas in viewpoint of asperity distribution. The seismic experiment using controlled source-OBS study in 1996 revealed strong correlation between seismic reflection intensity and the seismic activity in 38o40'N and 39o00'N on the forearc slope of the Japan Trench (Fujie et al., 2002). P-wave velocity structure under the NS-line can be represented by horizontal layering structure, and the plate boundary is located at slightly deeper depth than 10 km (Suyehiro and Nishizawa, 1994 and Fujie et al., 2000). In order to study 3-D distribution of seismic reflection intensity at the subdction plate boundary for this region, we carried out a seismic experiment in 2001 in a part of the area of the 1996 experiment, with a denser OBS array. Thirty-nine OBSs were placed on 30 km x 50 km along seven seismic lines. Airguns were used as artificial seismic sources, and their average total chamber volume was 57 liters. While making record sections, each trace was plotted at the mid point between the source and receiver locations so that reflected arrivals were plotted at their approximated reflection points. The distribution of seismic reflection intensity observed in this experiment agreed well with the result of Fujie, 2000. In their results, strong seismic reflections from plate boundary occur at aseismic region. The seismic reflection intensities were found to be largely heterogeneous over the surveyed area. We identified these reflected arrivals as reflections from plate boundary.

    Pulsating Aurora(PA) is characterized by the periodically changing emission amplitudes with the rectangular pulses of a few seconds to a few tens of seconds [e.g., Oguti et al., 1981; Yamamoto, 1988]. PAs tend to appear in the recovery phase of substorm between postmidnight and dawn sector. The horizontal size of PAs are known to be 10-200 km, based on the optical observations. Recently, some ground-satellite coordinated observations suggested the generation mechanisms of PAs as a result of pitch angle scatterings due to whistler mode chorus waves and/or the electron cyclotron harmonics[Nishimura et al., 2010; Liang et al., 2010]. Time-varying field aligned potential was also suggested by Sato et al. [2004]. The dominant mechanisms and the origin of the periodicity remain unclear. Ground-based all-sky observations have been made for a long time, although they were not enough for a quantitative discussion about small-scale characteristics of PAs such as the shapes and dynamics due to their limited spatial resolutions. The fast temporal variations of intensity known as quasi-3Hz modulations, which was reported by a number of rocket/satellite observations about precipitating electrons[e.g., Sandahl et al., 1980], has been hardly discussed in detail using the ground instruments because of the limited temporal resolutions and sensitivities. We have carried out ground-based observations using a suit of instruments, consisting of an EMCCD camera, an all-sky video camera, a photometer, and a search coil magnetometer covering the frequency range of ELF-VLF. We installed the instruments at Poker Flat Research Range between November 2010 and March 2011. Our EMCCD camera has narrow field of view corresponding to 100km × 100km at altitude of 110 km and high sampling rate up to 100 frames per second. An initial analysis result of event on March 4th 2011 around 1100UT revealed two important features of PAs in small scale. One is PAs in the FOV can be categorized into three regions which showed different periods. There were 1-3Hz modulations inside each patches, while there was no higher frequency modulations. In addition, simultaneous observations with the search coil demonstrated that modulations of PA ranged 1 to 3Hz correlated to ELF amplitudes integrated over frequency range of 1-10Hz. On the other hand, VLF emissions corresponding to whistler mode waves were not seen during this period. Isolated PA seen around UT14:30 on the same day showed continuous modulations with peak at 3Hz and no correlations to ELF amplitudes. These results demonstrate that the temporal and spatial characteristics of PA, such as periodicity, modulation and micro-shapes, varies considerably with MLT in a narrow region corresponding to about 2000km × 2000km in the magnetosphere. It means that the generation processes depend greatly on local plasma conditions and the conditions are nonuniform in the source regions.

    Urban Heat Island (UHI) is an urban climate phenomenon, which is described by the occurrence of temperatures that are higher over urban surfaces than over surrounding rural areas of similar elevation. The phenomenon is particularly pronounced during night-time. UHI is primarily driven by the shortwave incoming radiation energy reaching the urban surface, which has very different physical properties from rural areas. Contemporary technologies such as airborne/satellite remote sensing, offer unique capabilities for mapping and monitoring UHI at different spatial and temporal scales, and ideally extend and complement ground-based techniques. To assist in understanding the UHI effect and its complexities in European cities through the combination of spacecraft remote sensing and ground-based observations, a relevant project entitled "Urban Heat Islands and Urban Thermography" was launched recently by the European Space Agency (ESA). In the framework of the aforementioned project, the "Thermopolis 2009" campaign was implemented by a wide consortium in Athens during the summer of 2009, with the aim to provide a mapping of parameters related to the characterization of UHI at different spatial scales. During the Thermopolis campaign abundant airborne and satellite observations concurrently to ground measurements were collected for the study site. This paper aims to present results from the analysis of the different spatial scale datasets collected during the Thermopolis campaign, discussing also various aspects of the UHI for the studied region, on which the analysis has been conducted thus far.

  12. Obtaining identical results with double precision global accuracy on different numbers of processors in parallel particle Monte Carlo simulations

    We describe and compare different approaches for achieving numerical reproducibility in photon Monte Carlo simulations. Reproducibility is desirable for code verification, testing, and debugging. Parallelism creates a unique problem for achieving reproducibility in Monte Carlo simulations because it changes the order in which values are summed. This is a numerical problem because double precision arithmetic is not associative. Parallel Monte Carlo, both domain replicated and decomposed simulations, will run their particles in a different order during different runs of the same simulation because the non-reproducibility of communication between processors. In addition, runs of the same simulation using different domain decompositions will also result in particles being simulated in a different order. In [1], a way of eliminating non-associative accumulations using integer tallies was described. This approach successfully achieves reproducibility at the cost of lost accuracy by rounding double precision numbers to fewer significant digits. This integer approach, and other extended and reduced precision reproducibility techniques, are described and compared in this work. Increased precision alone is not enough to ensure reproducibility of photon Monte Carlo simulations. Non-arbitrary precision approaches require a varying degree of rounding to achieve reproducibility. For the problems investigated in this work double precision global accuracy was achievable by using 100 bits of precision or greater on all unordered sums which where subsequently rounded to double precision at the end of every time-step.

    Apfel's excellent match: This series of photos shows a water drop containing a surfactant (Triton-100) as it experiences a complete cycle of superoscillation on U.S. Microgravity Lab-2 (USML-2; October 1995). The time in seconds appears under the photos. The figures above the photos are the oscillation shapes predicted by a numerical model. The time shown with the predictions is nondimensional. Robert Apfel (Yale University) used the Drop Physics Module on USML-2 to explore the effect of surfactants on liquid drops. Apfel's research of surfactants may contribute to improvements in a variety of industrial processes, including oil recovery and environmental cleanup.

    Gas based time projection chambers (TPCs) have been shown to be highly sensitive X-ray polarimeters having excellent quantum efficiency while at the same time achieving large modulation factors . To observe polarization of the prompt X-ray emission of a Gamma-ray burst (GRB), a large area detector is needed. Diffusion of the electron cloud in a standard TPC could be prohibitive to measuring good modulation when the drift distance is large. We propose using a negative ion TPC (NITPC) with Nitromethane (CH3NO2) as the electron capture agent. An NITPC will have improved diffusion characteristics due to the thermal coupling of the negative ion to the surrounding gas and reduced electronic power consumption due to the slower velocity of the negative ions. We present results from tests of a single and double GEM TPC and NITPC. SciEnergy GEMs of 3x3 cm^2 and 2x5 cm^2 were used in the experiment and tested with various concentrations and pressures of P10, NeCO2 and NeCO2CH3NO2. Gain curves, photoelectron tacks and modulation curves will be presented for each instrument.

    1994-01-01

    White noise stimuli were used to estimate second-order kernels for complex cells in cortical area V1 of the macaque monkey, and drifting grating stimuli were presented to the sample of neurons to obtain orientation and spatial-frequency tuning curves. Using these data, we quantified how well second-order kernels predict the normalized tuning of the average response of complex cells to drifting gratings. The estimated second-order kernel of each complex cell was transformed into an interaction function defined over all spatial and temporal lags without regard to absolute position or delay. The Fourier transform of each interaction function was then computed to obtain an interaction spectrum. For a cell that is well modeled by a second-order system, the cell's interaction spectrum is proportional to the tuning of its average spike rate to drifting gratings. This result was used to obtain spatial-frequency and orientation tuning predictions for each cell based on its second-order kernel. From the spatial-frequency and orientation tuning curves, we computed peaks and bandwidths, and an index for directional selectivity. We found that the predictions derived from second-order kernels provide an accurate description of the change in the average spike rate of complex cells to single drifting sine-wave gratings. These findings are consistent with a model for complex cells that has a quadratic spectral energy operator at its core but are inconsistent with a spectral amplitude model. PMID:7918230

    Canine Hip Dysplasia (CHD) is still a significant health problem among dogs of so called predisposed breeds where this disease is revealed even among 30% individuals of the whole population. The present results were obtained by two clinics and deal with CHD occurrence among the most frequently and predisposed breeds in Olsztyn and Siemianowice Slaskie/Upper Silesia, Poland. Radiographs of hip joints were described using Riser's method. Altogether 2279 dog were examined including 2113 animals which were analysed. The German Shepherd Dog was the prevalent breed found in both clinics, but CHD was not common in this breed. In the Olsztyn Clinic, the most numerous group affected by CHD was Neapolitan Mastiff (60%), while in the Siemianowice Slaskie Clinic, dysplasia dominated in Bernese Mountain Dog (46%).

    The susceptibility of 211 clinical isolates of Mycobacterium tuberculosis complex (201 M. tuberculosis and 10 Mycobacterium bovis isolates) to pyrazinamide (PZA) was assessed by the nonradiometric Bactec MGIT 960 system (M960). Detection of PZA resistance was followed by a repeat testing using a reduced inoculum (RI) of 0.25 ml instead of 0.5 ml. According to the first M960 analysis, resistance was observed in 55 samples. In the RI assay, 32 samples turned out to be susceptible and 23 proved to be resistant (58.2% false positivity). The Bactec 460 assay confirmed as resistant those strains detected by the RI assay, while discrepant results were found susceptible. Mutation analysis performed on 13 M. tuberculosis isolates detected pncA mutations in 11 samples. On the basis of our data, we suggest using the RI assay to confirm all PZA resistance results obtained with the standard M960 assay. Further studies are required to confirm our findings.

  14. Excellent lubricating behavior of Brasenia schreberi mucilage.

    2012-05-22

    The present work reports an excellent lubrication property of an aquatic plant called Brasenia schreberi (BS). To investigate the lubrication characteristics of the BS mucilage, a novel measuring system is designed, and an ultralow friction coefficient about 0.005 between the mucilage and glass surface has been obtained. It is found that the ultralow friction is closely related to the structure of mucilage and water molecules in the mucilage. The microstructure analysis indicates that the mucilage surrounding BS forms a kind of polysaccharide gel with many nanosheets. A possible lubrication mechanism is proposed that the formation of hydration layers among these polymer nanosheets with plenty of bonded water molecules causes the ultralow friction. The excellent lubrication property has a potential application for reducing the friction between a glossy pill coated with such layer of mucilage and people's throats. PMID:22548346

    Selection programmes are mainly concerned with increasing genetic gain. However, short-term progress should not be obtained at the expense of the within-population genetic variability. Different prediction models for the evolution within a small population of the genetic mean of a selected trait, its genetic variance and its inbreeding have been developed but have mainly been validated through Monte Carlo simulation studies. The purpose of this study was to compare theoretical predictions to experimental results. Two deterministic methods were considered, both grounded on a polygenic additive model. Differences between theoretical predictions and experimental results arise from differences between the true and the assumed genetic model, and from mathematical simplifications applied in the prediction methods. Two sets of experimental lines of chickens were used in this study: the Dutch lines undergoing true truncation mass selection, the other lines (French) undergoing mass selection with a restriction on the representation of the different families. This study confirmed, on an experimental basis, that modelling is an efficient approach to make useful predictions of the evolution of selected populations although the basic assumptions considered in the models (polygenic additive model, normality of the distribution, base population at the equilibrium, etc.) are not met in reality. The two deterministic methods compared yielded results that were close to those observed in real data, especially when the selection scheme followed the rules of strict mass selection: for instance, both predictions overestimated the genetic gain in the French experiment, whereas both predictions were close to the observed values in the Dutch experiment.

    The Sahelian belt of West Africa is a semiarid region characterized by wide climate variations, which can in turn affect the livelihood of local populations particularly in rangeland areas, as happens during the dramatic food crisis in the 70-80s caused by rainfall scarcity. The monitoring of natural resources and rainfed agricultural activities, with the aim to provide information to support Sahelian food security action, needs the production of detailed thematic maps as emphasized by several scientific papers. In this framework, a study was conducted to develop a method to exploit time series of remote sensed satellite data to 1) provide reliable land cover (LC) map at local scale in a dry region and 2) obtain a LC change (LCC) map that contribute to identify the plausible causes of local environmental instability. Satellite images used for this work consist in a time series of Landsat Thematic Mapper (TM) (path row 195-50) acquired in the 2000 (6 scenes) and 2007 (9 scenes) from February (Dry season) to September (end of wet season). The study investigates the different contribution provided by spectra information of a single Landsat TM image and by time series of derived NDVI. Different tests have been conducted with different combination of data set (spectral and temporal)in order to identify the best approach to obtain a LC map in five classes of interest: Shrubland, Cultivated Land, Water body, Herbaceous vegetation and Bare soil. The best classification approach is exposed and applied on two years in the last decade. The comparison between this two LC results in land cover change map, that displays the changes of vegetation patterns that have been characterized the area. The discussed results show a largely stable dryland region, but locally characterized by hot-spot of decreasing in natural vegetation inside the rangelands and an increasing of cultivations along fossil valleys where human activities are slightly intense. The discussion shows that this hot-spot aren't fully explained by climatic variability as displayed by a comparison with rainfall satellite data, and suggest that there are localized area where vegetation development is driven by other anthropic factors which interfere in the dynamics of plant growing.

    The author has identified the following significant results. Soil resource studies in Brazil have concluded that: areas with agricultural activities appear surrounding urban centers; some areas are suffering a strong erosion action; there exist two drainage systems near Paraguai River and Parana River; and this region possesses great variety of soil types. It is possible to count the number of lakes and sluices as well as their superficial area using a channel 7 photographic enlargement. The great concentration of water bodies along the Jacui River determines the large rice crops. Data concerning regions around Teresina City, Presidente Prudente, Piracicaba City, Dourados, and Tres Marias Dam revealed several characteristics concerning the soil and water resources. Two basic maps were made of the natural vegetation distribution over central eastern Brazil from data ERTS-1 data. One map shows the drainage system, the road system, and cities; while the second shows the natural vegetation. It was possible to identify old reforestation, new reforestation, natural forest in flat lands, and natural forest in rolling lands from the ERTS images. Different pasture plant species could be identified by multispectral remote sensing. Data obtained along different wavelength bands provide essential data for the range manager to evaluate his range and to establish a suitable policy. Hydrographic mapping was done using the ERTS images.

    Engineering technology curricula stress hands on training and laboratory practices in most of the technical courses. Laboratory reports should include analytical as well as graphical evaluation of experimental data. Experience shows that many students neither have the mathematical background nor the expertise for graphing. This paper briefly describes the procedure and data obtained from a number of experiments such as spring rate, stress concentration, endurance limit, and column buckling for a variety of materials. Then with a brief introduction to Microsoft Excel the author explains the techniques used for linear regression and logarithmic graphing.

    Biochemical analysis of the vitreous humor from the eye is an accepted accessory test for post-mortem investigation of cause of death. Modern biochemical analyzers allow testing of a range of analytes from a sample. However, it is not clear which analytes should be requested in order to prevent unnecessary testing (and expense). The means and standard deviation of the values obtained from analysis of the vitreous humor for sodium, potassium, chloride, osmolality, glucose, ketones (?-hydroxybutyrate), creatinine, urea, calcium, lactate, and ammonia were calculated from which the contribution of each analyte was reviewed in the context of post-mortem findings and final cause of death. For sodium 32 cases were regarded as high (more than one standard deviation above the mean), from which 9 contributed to post-mortem diagnosis [drowning (4), heat related death (2), diabetic hyperglycemia (2), and dehydration (1)], but 25 low values (greater than one standard deviation below the mean) made no contribution. For chloride 29 high values contributed to 4 cases--3 drowning and 1 heat-related, but these were all previously identified by a high sodium level. There were 29 high and 35 low potassium values, none of which contributed to determining the final cause of death. Of 22 high values of creatinine, 12 contributed to a diagnosis of renal failure. From 32 high values of urea, 18 contributed to 16 cases of renal failure (2 associated with diabetic hyperglycemia), 1 heat-related death, and one case with dehydration. Osmolarity contributed to 12 cases (5 heat-related, 4 diabetes, 2 renal failure, and 1 dehydration) from 36 high values. There was no contribution from 32 high values and 19 low values of calcium and there was no contribution from 4 high and 2 low values of ammonia. There were 11 high values of glucose, which contributed to the diagnosis of 6 cases of diabetic hyperglycemia and 21 high ketone levels contributed to 8 cases: 4 diabetic ketosis, 3 hypothermia, 3 ketosis of unknown cause, and 2 alcohol related deaths. A high lactate was identified in 25 cases, which contributed to 1 case with a diagnosis of metformin toxicity (1), but none of the 22 low lactate values contributed. The results of this audit have been used to reduce vitreous biochemistry test requests for sodium, osmolality, glucose, ketones, urea, and creatinine in most cases. Critical appraisal of each part of the post-mortem process should be undertaken to provide evidence to justify any investigative methods used in an autopsy. PMID:23852932

  10. Determination of hydraulic properties of the Callovo-Oxfordian argillite at the bure site: Synthesis of the results obtained in deep boreholes using several in situ investigation techniques

    NASA Astrophysics Data System (ADS)

    Distinguin, Marc; Lavanchy, Jean-Marc

    Since 1991, ANDRA ( Agence Nationale pour la gestion des Déchets Radioactifs - National Radioactive Waste Management Agency) has been performing research on the possibility of geologic disposal of high level radioactive waste. In 1999, Andra began constructing an Underground Research Laboratory at Bure, a site located on the border of the Meuse-Haute-Marne departments, 300 km East of Paris. The laboratory is investigating the Callovo-Oxfordian argillite, a 130 m thick middle Jurassic stratum, at a depth of about 420 m. Argillite is a clay-rich sedimentary rock with low-permeability. Between 1994 and 2004, Andra collected from deep boreholes an impressive wealth of data covering a wide range of geosciences. This paper focuses on the hydraulic data related to argillite, including the results from short-term hydraulic packer tests and long-term monitoring of the formation pressures. Three types of tools are used on the site for investigations in deep boreholes. The first one is a conventional packer test tool used in the petroleum industry and adapted for hydrogeological purposes. The main objective is to determinate the permeability of the formation through short-term tests (24-72 h) at about 10 regular intervals. The two other types of tool are permanent monitoring devices. The electromagnetic pressure gauge (EPG) is totally isolated from the surface perturbations. There are no electric or hydraulic lines to the surface and the borehole is cemented. The advantage of this tool is that the formation almost recovers its initial pressure, avoiding disturbances from surface. Although the multi-packer equipment, installed in an open borehole can be affected by surface perturbations, it is used to measure pressure at different isolated levels in the same borehole ( i. e., 11 chambers in one borehole). Evaluations of the formation pressure (freshwater head) and hydraulic conductivity have been performed for all intervals investigated (19 short-term packer tests and 15 long-term monitoring sections). Borehole simulators were used to define a suitable flow model taking into account the complete pressure history of the borehole, and to derive best-guess estimates and uncertainty ranges for the hydraulic parameters. The sources of perturbations and the consistency of results are discussed in this paper. For instance, for a same interval tested through different techniques, an overestimation by one order of magnitude of the hydraulic conductivity due to a large overestimation of pore pressure during packer test was observed. In situ permeability estimations are also compared with those obtained from laboratory tests on core samples. Both short-term and long-term measurements provide values for the hydraulic conductivity at different scales with high consistency. This parameter is shown to be less than 2 × 10 -12 m/s. Pressures measurements from long-term monitoring are sufficiently accurate for determining formation hydraulic heads. A pressure profile in the argillite, derived from the extensive set of data currently available, shows an overpressure in the argillite 20-60 m above its surrounding formations. As a whole, the pressure data and derived hydraulic properties acquired from deep boreholes, offer a high degree of reliability and constitute a major contribution to the hydraulic characterisation of the low-permeable argillite formation. In 2006, this data will be complemented with measurements carried out in the Laboratory at 490 m depth, with the aim to characterize in greater depth the pressure profile of the argillite.

    This paper presents application of satellite interferometric methods (persistent scatterer interferometric synthetic aperture radar (PSInSAR™) and differential interferometric synthetic aperture radar (DInSAR)) for observation of ground deformation in the Upper Silesian Coal Basin (USCB) in Southern Poland. The presented results were obtained during the DORIS project (EC FP 7, Grant Agreement n. 242212, www.doris-project.eu). Several InSAR datasets for this area were analysed. Most of them were processed by Tele-Rilevamento Europa - T.R.E. s.r.l. Italy. Datasets came from different SAR satellites (ERS 1 and 2, Envisat, ALOS- PALSAR and TerraSAR-X) and cover three different SAR bands (L, C and X). They were processed using both InSAR techniques: DInSAR, where deformations are presented as interferometric fringes on the raster image, and PSInSAR, where motion is indentified on irregular set of persistent scatterer (PS) points. Archival data from the C-band European Space Agency satellites ERS and ENVISAT provided information about ground movement since 1992 until 2010 in two separate datasets (1992-2000 and 2003-2010). Two coal mines were selected as examples of ground motion within inactive mining areas: Sosnowiec and Saturn, where mining ceased in 1995 and 1997, respectively. Despite well pumping after closure of the mines, groundwater rose several dozen meters, returning to its natural horizon. Small surface uplift clearly indicated on satellite interferometric data is related to high permeability of the hydrogeological subregion and insufficient water withdrawal from abandoned mines. The older 1992-2000 PSInSAR dataset indicates values of ground motion ranging from -40.0 to 0.0 mm. The newer 2003-2010 dataset shows values ranging from -2.0 to +7.0 mm. This means that during this period of time subsidence was less and uplift greater in comparison to the older dataset. This is even more evident in the time series of randomly selected PS points from both coal mines. The presence of bentonite deposits in the Saturn coal mine can also have influence on the ground surface uplift. Analysis of interferometric L and X-band data in Upper Silesia has enabled observation and monitoring of the underground mining front for several months. It was indicated by the example from the Halemba-Wirek coal mine. Analysis of the TerraSAR-X dataset processed by SqueeSAR algorithms proved to be the most effective for this purpose. X-band persistent scatterer interferometry (PSI) time series can help to indentify small seemingly negligible movements and are successfully supplemented by fringes when displacement becomes significant. Differential interferograms from the L-band dataset detect similar displacement values but, thanks to longer wavelength, are characterized by better coherence, especially in the middle of the subsidence trough. Results on ground deformation proved that ground motion above abandoned mines continues long after their closure. Therefore, existing regulations stating that abandoned mines are considered fully safe five years after mine closure should change. Moreover, it should be emphasised that construction in these areas should be avoided due to existing potential risks.

  12. Academic excellence workshops in chemistry and physics

    NASA Astrophysics Data System (ADS)

    Mills, Susan Rose

    In the mid-1970's, Uri Treisman, at the University of California, Berkeley, developed an academic excellence workshop program that had important successes in increasing minority student achievement and persistence in calculus. The present dissertation research is an in-depth study of chemistry and physics workshops at the California State Polytechnic University, Pomona. Data for the first, longitudinal component of this study were obtained by tracking to Spring 1998 all workshop minority students, i.e., Latino, African American, and Native American workshop students, a random sample of non-workshop minority students, and a random sample of non-targeted students, i.e., Anglo and Asian students, enrolled in first-quarter General Chemistry or Physics during specific quarters of 1992 or 1993. Data for the second component were obtained by administering questionnaires, conducting interviews, and observing science students during Fall, 1996. Workshop participation was a significant predictor of first-quarter course grade for minority students in both chemistry and physics, while verbal and mathematics Scholastic Aptitude Test (SAT) scores were not significant predictors of beginning course grade for minority science students. The lack of predictive ability of the SAT and the importance of workshop participation in minority students' beginning science course performance are results with important implications for educators and students. In comparing pre-college achievement measures for workshop and non-targeted students, non-targeted students' mathematics SAT scores were significantly higher than chemistry and physics workshop students' scores. Nonetheless, workshop participation "leveled the field" as workshop and non-targeted students performed similarly in beginning science courses. Positive impacts of workshop participation on achievement, persistence, efficiency, social integration, and self-confidence support the continued and expanded funding of workshop programs. This research also studied how gender and ethnicity affect attitudes, achievement, and persistence in science courses and mathematics-based majors. College-level females, both minority and non-minority, in science showed no differences from males or were in fact more positive about science than males. However, in interviews, minority females expressed concerns about gender and believed gender to be more important in their science experiences than ethnicity. This research suggests intervention programs to increase the number of females in the science- and technology-based job pipeline can be successful.

    A remarkable sedimentary record that extends from the Miocene to the late Pleistocene/Holocene has been drilled during IODP Expedition 341 (May - July 2013) in the Gulf of Alaska. The recovery and examination of sediments along a transect of five drill sites (U1417 - U1421) from the deep ocean towards the continental slope and shelf offshore the St. Elias Mountains enables the reconstruction of the palaeoceanographic and environmental development in the NE Pacific during a period of significant global cooling and directly addresses the overall research objectives of the IODP programme. The knowledge about palaeo sea surface conditions and their relation to climate changes in the subpolar NE Pacific is relatively scarce and mainly confined to the past 17 ka BP (Barron et al., 2009; Davies et al., 2011; Addison et al., 2012). Biomarker based reconstructions of the sea surface conditions (i.e. sea surface temperature (SST), sea ice coverage, marine primary productivity) that characterised the subpolar NE Pacific during critical time intervals of Plio- and Pleistocene climate change may provide new information on oceanic and atmospheric feedback mechanisms and further enable the identification of teleconnections between the palaeoceanographic evolution in the North Pacific and the North Atlantic. Here we present preliminary biomarker data obtained from sediments from the distal deepwater site U1417 and the proximal site U1419 located at the Gulf of Alaska continental slope. Variability in the distribution and abundance of short- and long-chain n-alkanes, sterols, and C25-highly branched isoprenoids (HBIs) is interpreted to reflect changes in the environmental setting. These data provide insight in marine primary productivity changes (in response to cooling and warming intervals) and the variable input of terrigenous organic matter via meltwater and/or iceberg discharge events. The C25-HBI diene/triene ratio - hitherto used as a sea ice proxy in the Southern Ocean (Etourneau et al., 2013) - is applied to gain information about the variability in polar water/sea ice extent in the study area. Previously, Rowland et al. (2001) documented that not only the degree of unsaturation in C25-HBIs but also the E- to Z-isomerisation in the C25-HBI trienes increases with increasing water temperature. Based on this observation we suggest that the ratio of the Z-isomer to the E-isomer in the trienes might reflect SST changes and could be used as an additional SST proxy. The applicability of this approach, however, needs further evaluation (e.g. through comparisons with alkenone SST data obtained from Expedition 341 sediments).

    This report summarizes information on State-sponsored 'Centers of Excellence' gathered during a survey of State programs in the Fall of 1987. For the purposes of this catalog, 'Centers of Excellence' refers to organizations or activities with the following characteristics: institutionalized, focused, cooperative Research and Development (R&D) programs; supported in part by State governments, in addition to universities, industry and (in some cases) Federal agencies; performed by teams that may include both industry and university employees; and concentrated on relatively specific R&D agendas, usually with near term commercial or governmental applicability. Most of these activities involve state-of-the-art advancement of new technologies under conditions leading to early practical applications. Not included in this catalog are project-level matching grant programs. The principal purpose of this catalog is to help NASA program management, at all levels. to identify and where appropriate, to initiate relationships with other technology-developing organizations. These State-sponsored programs should be of particular interest, because: they present an opportunity to leverage NASA's R&D investments; they are concentrated at the frontier, yet have a concern for practical applications; and they involve industrial participation under conditions that increase the probability of prompt, widespread dissemination in the form of new or enhanced commercial products, processes, or services.

    This Center-of-Excellence grant has two components: development of an imaging system based on microlaser arrays forms a central project among a group of laser diagnostic and therapeutic efforts primarily funded outside the grant. In these first 8 months we have set up the Microlaser Microscope using small microlaser arrays. We have emphasized the basics of microlaser handling and electronic addressing and the optics of the microscope. Details of electronics and optics given here will be used in the larger arrays which should be available soon. After a description of the central Microlaser Microscope project, we touch briefly on the other projects of the Center, which have been outstandingly fruitful this year. Publications are necessarily concerned with the smaller projects, since the Microlaser Microscope is in its early stages.

    We have tested the capability of a plasmid DNA (pDNA) expressing the EBV nuclear Ag-4 (EBNA-4) to evoke a T cell response-associated protective immune response against a tumor expressing this gene. We have found that ACA mice immunized with EBNA-4-expressing plasmid were partially protected against syngeneic mammary carcinoma line (S6C) expressing EBNA-4 (S6C-E4). This protection was enhanced by coimmunizing mice with EBNA-4- and GM-CSF-expressing plasmids, and a full protection was achieved by coimmunizing mice with EBNA-4- and IFN-gamma-expressing plasmids. Furthermore, mice that have rejected the EBNA-4-positive tumor were also resistant against a subsequent challenge with the original nontransfected tumor line. We then checked for the ability of pDNA immunization to provide a protective long-term memory response. We indeed found that even after 3 mo from the last immunization, full protection was obtained by this method, as compared with full tumor outgrowth in the control-immunized group. These findings support the concept that a nonviral, pDNA-based vaccination strategy is useful to fully protect from the outgrowth of tumors expressing this EBV gene. PMID:10570277

    Efforts have been made in Pakistan to create ethical guidelines for research and medical practice. This study explored the perceptions of and factors affecting the process of obtaining informed consent to surgery among inpatients and families at a tertiary-care hospital in Karachi. A random sample of 400 post-surgery adult patients answered a pre-tested, structured questionnaire. Overall, 233 patients (58.3%) had signed the surgery consent form themselves, while 167 relatives (41.7%) had signed on behalf of the patient. Perceived factors significantly associated with patients not signing the consent form themselves were: language used (adjusted OR = 4.6), medical terminology used (aOR = 2.7), insufficient time allocation (aOR = 3.8), cultural/traditional reasons (aOR = 1.5) and low education (aOR = 2.4). Inappropriate timing for taking consent and not being informed/asked about consent were not statistically significant factors. Health-care practitioners should encourage patients to sign the consent form themselves. PMID:25343470

    With the increased emphasis by Department of Energy personnel on assessing the environmental impact of past waste disposal practices at all of its facilities, there has been an associated increase in characterization activities that focus on delineating site-specific groundwater flow regimes and contaminant migration pathways. At the Oak Ridge Y-12 Plant, the complex geologic and hydrologic relationships require a more detailed understanding of the three-dimensional properties of groundwater flow regimes than can be obtained by conventional monitoring activities. Thus, as part of groundwater characterization activities conducted by the Environmental Surveillance Section staff of the Y-12 Plant Environmental Management Department, five existing deep core holes were instrumented with multiport monitoring systems to provide greatly enhanced resolution of the hydraulic and hydrochemical properties of the groundwater system within Bear Creek Valley. With a multiport system, it is possible to measure hydraulic head and hydraulic conductivity and collect water samples from multiple levels within a single borehole. In this report, multiport data collected during fiscal years (FYs) 1990 and 1991 are summarized.

    Smoking-related diseases can be attributed to the inhalation of many different toxins, including heavy metals, which have a host of detrimental health effects. The current study reports the levels of arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), and lead (Pb) in cigarettes obtained from adult smokers participating in the 2009 wave of the ITC United States Survey (N = 320). The mean As, Cd, Cr, Ni, and Pb levels were 0.17, 0.86, 2.35, 2.21, and 0.44 µg/g, respectively. There were some differences in metal concentrations of cigarette brands produced by different manufacturers, suggesting differences in the source of tobaccos used by different companies. For Ni, there were significant pairwise differences between Philip Morris U.S. (PMUSA) and R.J. Reynolds (RJR) brands (PMUSA higher; p < 0.001), PMUSA and other manufacturer (OM) brands (PMUSA higher; p < 0.001), and RJR and OM brands (RJR higher; p = 0.006). For Cr, RJR brands had higher levels than did OM brands (p = 0.02). Levels of As, Cd, and Pb did not differ significantly across manufacturer groups (p > 0.10). Because of the variety of toxic heavy metals in cigarette tobacco, and their numerous negative health effects, metal content in cigarette tobacco should be reduced. PMID:24452255

    Standard vein graft (SVG) and inside out vein graft (IOVG) techniques to promote peripheral nerve regeneration have been widely studied since last two decades. In this experimental study, we attempted to compare these two techniques and analyze the differences in the expression of the neurotrophins during peripheral nerve regeneration. Thirty-six male Wistar rats were used in this sciatic nerve transection model and were divided into two experimental groups (SVG and IOVG) and one sham operated control group. An overall defect of 10 mm was made in the sciatic nerve of the animals in the experimental groups. Each group consisted of two time intervals of 6 and 12 weeks (n = 6). After each experimental interval, sciatic functional index (SFI) along with area and diameter of the axons and fibers of each group were calculated. Muscle mass measurements were also evaluated to see any functional recovery in the groups. Expression of neurotrophins in the graft and distal stump were analyzed with the help of RT-PCR. SFI obtained from walking track analysis showed poor motor recovery in the experimental groups during both time intervals. No significant differences in the histological, morphometric (P > 0.05), and muscle mass measurements (P > 0.05) between the two experimental groups were observed. Analysis of RT-PCR data exhibited an increase in the expression of NT-3 with time in both the grafts (6 weeks 0.428 ± 0.392, 12 weeks 1.089 ± 0.455, P < 0.05) and distal stump (6 weeks 0.411 ± 0.306, 12 weeks 0.807 ± 0.303, P < 0.05) of the SVG group. The study concludes that there is no substantial difference in the nerve regeneration ability between both the techniques. Also, the difference in the level of NT-3 between SVG and IOVG suggests a distinct regulation of NT-3 in peripheral nerve regeneration. © 2014 Wiley Periodicals, Inc. Microsurgery, 2014.

    Samples from five monogenetic volcanoes in the Quaternary Auckland volcanic field that record the same geomagnetic excursion have been investigated using the microwave palaeointensity technique. Both the perpendicular applied field method and Coe version of the Thellier technique were carried out, with sister sub samples being run in many cases to check for consistency. The experiments were performed using the Liverpool microwave systems operating at 14 GHz. A total of 58 samples gave results ranging from 1 to 24 ?T with the mean palaeointensity per volcano ranging from 7 to 17 ?T. Mochizuki et al (2006 Phys. Earth Planet. Int., 154, 168-179) previously studied samples from three of the five volcanoes using the LTD-DHT Shaw palaeointensity method. Their results from 17 samples showed greater consistency both between and within volcanoes. Possible reasons for the differences between results from the microwave method and LTD-DHT Shaw method will be discussed. Despite the differences, both overall mean palaeointensities are statistically indistinguishable and show that the geomagnetic dipole moment was reduced to about 2 x 1022 Am2 for this Auckland excursion.

    Report presents the results of tests of a 1/10-scale model of the XN2Y-1 airplane tested in the NACA 5-foot vertical wind tunnel in which the six components of forces and moments were measured. The model was tested in 17 attitudes in which the full-scale airplane had been observed to spin, in order to determine the effects of scale, tunnel, and interference. In addition, a series of tests was made to cover the range of angles of attack, angles of sideslip, rates of rotation, and control setting likely to be encountered by a spinning airplane. The data were used to estimate the probable attitudes in steady spins of an airplane in flight and of a model in the free-spinning tunnel. The estimated attitudes of steady spin were compared with attitudes measured in flight and in the spinning tunnel. The results indicate that corrections for certain scale and tunnel effects are necessary to estimate full-scale spinning attitudes from model results.

    Those inhabitants of Hiroshima and Nagasaki who were affected by the A-bomb explosions, were exposed to a mixed neutron and gamma radiation field. Few years later about 120,000 survivors of both cities were selected, and since then radiation-induced late effects such as leukemia and solid tumors are being investigated in this cohort. When the present study was initiated, the fast neutron fluences that caused the neutron doses of these survivors had never been determined experimentally. In principle, this would have been possible if radioisotopes produced by fast neutrons from the A-bomb explosions had been detected in samples from Hiroshima and Nagasaki at distances where the inhabitants survived. However, no suitable radioisotope had so far been identified. As a contribution to a large international effort to re-evaluate the A-bomb dosimetry, the concentration of the radionuclide (63)Ni (half-life 100.1 years) has been measured in copper samples from Hiroshima and Nagasaki. These measurements were mainly performed at the Maier-Leibnitz-Laboratory in Munich, Germany, by means of accelerator mass spectrometry. Because the (63)Ni had been produced in these samples by fast A-bomb neutrons via the reaction (63)Cu(n,p)(63)Ni, these measurements allow direct experimental validation of calculated neutron doses to the members of the LSS cohort, for the first time. The results of these efforts have already been published in a compact form. A more detailed discussion of the methodical aspects of these measurements and their results are given in the present paper. Eight copper samples that had been significantly exposed to fast neutrons from the Hiroshima A-bomb explosion were investigated. In general, measured (63)Ni concentrations decreased in these samples with increasing distance to the hypocenter, from 4 x 10(6 ) (63)Ni nuclei per gram copper at 391 m, to about 1 x 10(5 ) (63)Ni nuclei per gram copper at about 1,400 m. Additional measurements performed on three large-distant copper samples from Hiroshima (distance to the hypocenter 1,880-7,500 m) and on three large-distant copper samples from Nagasaki (distance to the hypocenter 3,931-4,428 m) that were not exposed significantly to A-bomb neutrons, suggest a typical background concentration of about 8 x 10(4 ) (63)Ni nuclei per gram copper. If the observed background is accounted for, the results are consistent with state-of-the-art neutron transport calculations for Hiroshima, in particular for those distances where the victims survived and were included in the life span study cohort.

    In order to achieve the second-order advantage, second-order data per sample is usually required, e.g., kinetic-spectrophotometric data. In this study, instead of monitoring the time evolution of spectra (and collecting the kinetic-spectrophotometric data) replicate spectra are used to build a virtual second order data. This data matrix (replicate mode×?) is rank deficient. Augmentation of these data with standard addition data [or standard sample(s)] will break the rank deficiency, making the quantification of the analyte of interest possible. The MCR-ALS algorithm was applied for the resolution and quantitation of the analyte in both simulated and experimental data sets. In order to evaluate the rotational ambiguity in the retrieved solutions, the MCR-BANDS algorithm was employed. It has been shown that the reliability of the quantitative results significantly depends on the amount of spectral overlap in the spectral region of occurrence of the compound of interest and the remaining constituent(s).

  12. Quantity and quality of black carbon molecular markers as obtained by two chromatographic methods (GC-FID and HPLC-DAD) - How do results compare?

    Chars produced by wildfires are an important source of black carbon (BC) in the environment. After their deposition on the soil surface they can be distributed into rivers, marine waters and sediments. The analysis of benzenepolycarboxylic acids (BPCAs) as a quantitative measure for black carbon (BC) in soil and sediment samples is a well-established method (Glaser et al., 1998; Brodowski et al., 2005). Briefly, the nitric acid oxidation of fused aromatic ring systems in BC forms eight molecular markers (BPCAs), which can be assigned to BC, and which subsequently can be quantified by GC-FID (gas chromatography with flame ionization detector). Recently, this method was modified for the quantification of BC in seawater samples using HPLC-DAD (High performance liquid chromatography with diode array detector) for the determination of individual BPCAs (Dittmar, 2008). A direct comparison of both analytical techniques is lacking but would be important for future data comparison aimed at the calculation of global BC budgets. Here we present a systematic comparison of the two BPCA quantification methods. We prepared chars under well-defined laboratory conditions. In order to cover a broad spectrum of char properties we used two sources of biomass and a wide range of pyrolysis temperatures. Chestnut hardwood chips (Castanea sativa) and rice straw (Oryza sativa) were pyrolysed at temperatures between 200 and 1000°C under a constant N2 stream. The maximum temperatures were held constant for 5 hours (Hammes et al., 2006). The BC contents of the chars have been analysed using the BPCA extraction method followed by either GC-FID or HPLC-DAD quantification. Preliminary results suggest that both methods yield similar total quantities of BPCA, and also the proportions of the individual markers are similar. Ongoing experiments will allow for a more detailed comparison of the two methods. The BPCA composition of chars formed at different temperatures and from different precursor biomass is being used for this purpose. We seek to establish a conversion factor between both methods, if required. Results show that both the GC and the HPLC method can be used for organic samples containing some silica, such as grass char. Further tests include silica-rich materials, such as soils. Ongoing methodological work aims at carbon isotope analysis (13C and 14C) on individual BPCAs isolated via HPLC. At present the HPLC method employs tetrabutyl ammonium bromide (TBAB) as a modifier for the liquid phase. TBAB is not volatile and contains carbon, it therefore prevents carbon isotopic analysis on isolated BPCAs. References Brodowski, S., Rodionov, A., Haumeier, L., Glaser, B., Amelung, W.

    Despite extensive efforts, low efficiency is still an issue in bovine somatic cell nuclear transfer (SCNT). The hypothesis of our study was that the use of cytoplasts produced by chemically assisted enucleation (EN) would improve nuclear reprogramming in nuclear transfer (NT)-derived embryos because it results in lower damage and higher cytoplasm content than conventional EN. For that purpose, we investigated the expression of two X-linked genes: X inactive-specific transcript (XIST) and glucose 6-phosphate dehydrogenase (G6PD). In the first experiment, gene expression was assessed in day-7 female blastocysts from embryonic cell NT (ECNT) groups [conventional, ECNT conv; chemically assisted, ECNT deme (demecolcine)]. Whereas in the ECNT conv group, only one embryo (25%; n=4) expressed XIST transcripts, most embryos showed XIST expression (75%; n=4) in the ECNT deme group. However, no significant differences in transcript abundance of XIST and G6PD were found when comparing the embryos from all groups. In a second experiment using somatic cells as nuclear donors, we evaluated gene expression profiles in female SCNT-derived embryos. No significant differences in relative abundance (RA) of XIST transcripts were observed among the groups. Nonetheless, higher (p<0.05) levels of G6PD were observed in SCNT deme and in vitro-derived groups in comparison to SCNT conv. To know whether higher G6PD expression in embryos derived from SCNT chemically assisted EN indicates higher metabolism in embryos considered of superior quality or if the presence of higher reactive oxygen species (ROS) levels generated by the increased oxygen consumption triggers G6PD activation, the expression of genes related to stress response should be investigated in embryos produced by that technique.

    Objectives To compare the validity of parent-reported height, weight and body mass index (BMI) values of children (aged 4–10?years), when measured at home by means of newly developed instruction leaflets in comparison with simple estimated parental reports. Design Randomised controlled trial with control and intervention group using simple randomisation. Setting Belgian children and their parents recruited via schools (multistage cluster sampling design). Participants 164 Belgian children (53% male; participation rate 62%). Intervention Parents completed a questionnaire including questions about the height and weight of their child. Parents in the intervention group received instruction leaflets to measure their child's weight and height. Classes were randomly allocated to the intervention and control groups. Nurses measured height and weight following standardised procedures up to 2?weeks after parental reports. Outcome measures Weight, height and BMI category of the child were derived from the index measurements and the parental reports. Results Mean parent-reported weight was slightly more underestimated in the intervention group than in the control group relative to the index weights. However, for all three parameters (weight, height and BMI), correlations between parental reports and nurse measurements were higher in the intervention group. Sensitivity for underweight and overweight/obesity was respectively, 75% and 60% in the intervention group, and 67% and 43% in the control group. Weighed ? for classifying children in the correct BMI category was 0.30 in the control group and was 0.51 in the intervention group. Conclusions Although mean parent-reported weight was slightly more underestimated in the intervention than in the control group, correlations were higher and there was considerably less misclassification into valid BMI categories for the intervention group. This pattern suggests that most of the parental deviations from the index measurements were probably due to random errors of measurement and that diagnostic measures could improve by encouraging parents to measure their children's weight and height at home by means of instruction leaflets.

  17. Results from Mobile Lab Measurements Obtained in the Barnett Shale with Emphasis on Methane and Gaseous Mercury Emissions (Fort Worth, TX)

    2013-12-01

    Our work is part of a comprehensive analysis conducted through a collaboration of ground based measurements and airborne measurements with several research groups in order to gain a better understanding of methane and mercury emissions in the Barnett Shale. It's a vast rock formation that sits in the 5,000 square miles surrounding the Fort Worth area. To get the gas to market requires an underground highway of pipelines and compression stations. Texas state records show that since 2000 the number of gas compressors in the Barnett Shale has tripled (from a few hundred to 1,300), and they're ever infringing on populated areas. Recent preliminary data reported by Pétron et al. and Tollefson et al. (from the natural-gas operations in Denver-Julesburg Basin) point to CH4 loss from the process of 4-8%, not including additional losses in the pipeline and distribution system. Additionally, Howarth et al. have conducted a comprehensive analysis of greenhouse gases (methane, in particular) emitted from shale gas as a result of hydraulic fracturing and they estimate up to 8% of all natural gas mined from shale formations leaks to the atmosphere. Not only is this cause for alarm due to the global warming potential of methane, but we would expect similar losses of additional (potentially harmful) gases, i.e., atmospheric Hg, from the extraction systems. These preliminary findings are higher than the current U.S. Environment Protection Agency (EPA) leakage estimate of 2.3 percent. Our strategy employs the use of our mobile laboratory, a four door Chevrolet Silverado pickup truck with a camper shell, outfitted with trace gas instrumentation including a Picarro G2132i and a Tekran 2537 mercury analyzer. The Picarro cavity ring down instrument has high precision and accuracy H2O, CO2, CH4, and 13?C in CH4 and CO2 with very little drift due to precise temperature and pressure controls. The Tekran mercury analyzer allows for accurate total gaseous mercury measurements via employment of cold vapor atomic fluoresence spectroscopy. This work offers quantification of the spurious emissions associated with natural gas fracking in the Fort Worth area.

    Background Role modeling is an integral component of medical education. The literature suggests that being a clinically excellent academic physician and serving as a role model for trainees are integrally related. Purpose To explore the relationship between being considered clinically excellent and being considered an effective role model. Methods Two independent surveys were administered to clinically active faculty (asked to name clinically excellent colleagues) and internal medicine residents (asked to name faculty role models). We compared frequency counts of clinically excellent faculty mentioned and frequency counts of role models mentioned by respondents. Spearman correlations and odds ratios with 95% confidence intervals were used to assess the relationship between the responses. Results A total of 39 of 66 faculty (59%) and 45 of 50 residents (90%) responded. There were 31 faculty members judged to be clinically excellent and 67 faculty identified as role models. Thirty faculty members appeared on both lists. There was a moderately high correlation between these groups (Spearman correlation coefficient ?=? 0.54, P < .001). Faculty members who were among those named as clinically excellent by their peers were more likely to be named 3 or more times as a role model by trainees (odds ratio, 24.6; confidence interval, 2.9–207). Conclusions This study tested and confirmed the correlation between clinical excellence and role modeling, illustrating the value of these faculty members at teaching hospitals. PMID:23205192

  20. Simplifying CEA through Excel, VBA, and Subeq

    Many people use compound equilibrium programs for very different reasons, varying from refrigerators to light bulbs to rockets. A commonly used equilibrium program is CEA. CEA can take various inputs such as pressure, temperature, and volume along with numerous reactants and run them through equilibrium equations to obtain valuable output information, including products formed and their relative amounts. A little over a year ago, Bonnie McBride created the program subeq with the goal to simplify the calling of CEA. Subeq was also designed to be called by other programs, including Excel, through the use of Visual Basic for Applications (VBA). The largest advantage of using Excel is that it allows the user to input the information in a colorful and user-friendly environment while allowing VBA to run subeq, which is in the form of a FORTRAN DLL (Dynamic Link Library). Calling subeq in this form makes it much faster than if it were converted to VBA. Since subeq requires such large lists of reactant and product names, all of which can't be passed in as an array, subeq had to be changed to accept very long strings of reactants and products. To pass this string and adjust the transfer of input and output parameters, the subeq DLL had to be changed. One program that does this is Compaq Visual FORTRAN, which allows DLLs to be edited, debugged, and compiled. Compaq Visual FORTRAN uses FORTRAN 90/95, which has additional features to that of FORTRAN 77. My goals this summer include finishing up the excel spreadsheet of subeq, which I started last summer, and putting it on the Internet so that others can use it without having to download my spreadsheet. To finish up the spreadsheet I will need to work on debugging current options and problems. I will also work on making it as robust as possible, so that all errors that may arise will be clearly communicated to the user. New features will be added old ones will be changed as I receive comments from people using the spreadsheet. To implement this onto the Internet, I will need to develop an XML input/output format and learn how to write HTML.

Until recently, clinical excellence had not been defined, and the extent to which this recently published definition applies to the care of patients with psychiatric illness is not known. This article sets out to consider how the paradigm for clinical excellence applies to the field of psychiatry. Data Source: PubMed, Ovid MEDLINE, and PsycINFO were searched (1962 through December 2010) combining the keywords psychiatry (or psychiatrist) and clinical excellence, limiting the output to English-language case reports. In subsequent searches, the term clinical excellence was replaced by each of the components of the definition: communication and interpersonal skills, professionalism and humanism, diagnostic acumen, skillful negotiation of the health care system, knowledge, scholarly approach to clinical practice, exhibiting a passion for patient care, explicitly modeling mastery to medical trainees, and collaborating with investigators to advance science and discovery. Study Selection: The search yielded 218 case reports. All of the case reports were reviewed, and a consensus was reached on the 8 exemplars and 1 teaching model to be presented in the article. Careful consideration was given as to whether any aspects of the framework for clinical excellence were missing or not applicable for psychiatry. Results Every case report reviewed touched on 1 or more of the domains of clinical excellence. None of the case reports uncovered new aspects of clinical excellence that were not described in the existing definition. Conclusions: This review of the case reports published in psychiatry reveals that the definition of clinical excellence described in this article may be highly applicable to those caring for patients with psychiatric illness.

    BREEAM is gaining popularity in the UK. Similar green building standards have gained popularity worldwide. However, it is important that we analyse the actual value added to a business by having a BREEAM rated facility. It is also important to analyze the impact on employee performance of such a facility. This paper presents a case study of a BREEAM excellent rated building with impact on the morale and performance of the employees. The data for the paper was collected using semi-structured interviews of a group of employees who work at this facility located in Glasgow. The results suggest that it is important to highlight the tangible benefits and value added through the implementation of the BREEAM standard.

    Adelson, R

    1997-01-01

    Total Quality Management (TQM) provides a philosophy and a method for organizational renewal and redesign. It is based on the principle that productive work is accomplished through processes. Improving these processes requires the office team to objectively measure performance, discover root causes of problems, take corrective action, determine the effect of these actions, and secure achievements. TQM is a technique that provides a series of steps and set of tools. Through staff involvement and a desire for quality improvement, organizations involved in total quality note the accompanying satisfaction in taking constructive action, improving patient relations, and achieving service excellence. In today's competitive delivery environment, implementation of TQM can result in more satisfied patients, higher staff morale, and a more effective office team. PMID:9161134

    Background Determining what constitutes an excellent allied health care professional (AHCP) is important, since this is what will guide the development of curricula for training future physical therapists, oral hygienists, speech therapists, diagnostic radiographers, and dietitians. This also determines the quality of care. Aim To describe perspectives of AHCPs on which characteristics are commonly associated with an excellent AHCP. Methods AHCPs’ perspectives were derived from three focus group discussions. Twenty-one health care professionals participated. The final analysis of the focus group discussions produced eight domains, in which content validity was obtained through a Delphi panel survey of 27 contributing experts. Results According to the survey, a combination of the following characteristics defines an excellent AHCP: (1) cognizance, to obtain and to apply knowledge in a broad multidisciplinary health care field; (2) cooperativity, to effectively work with others in a multidisciplinary context; (3) communicative, to communicate effectively at different levels in complex situations; (4) initiative, to initiate new ideas, to act proactively, and to follow them through; (5) innovative, to devise new ideas and to implement alternatives beyond current practices; (6) introspective, to self-examine and to reflect; (7) broad perspective, to capture the big picture; and (8) evidence-driven, to find and to use scientific evidence to guide one’s decisions. Conclusion The AHCPs perspectives can be used as a reference for personal improvement for supervisors and professionals in clinical practice and for educational purposes. These perspectives may serve as a guide against which talented students can evaluate themselves. PMID:24049449

    PubMed

    Lancaster, J

    1985-01-01

    Some people are motivated to achieve in a manner consistent with the goals of their organization while others pursue individual goals. The attitudes people hold determine their behavior. Therefore, the manager is charged with creating an environment that fosters employee commitment to organizational goals. To create a climate for achievement, managers must recognize that all employees want recognition. Employees perform more effectively when they understand the goals of the organization, know what is expected of them, and are part of a system that includes feedback and reinforcement. Generally, people perform more effectively in an environment with minimal threat and punishment; individual responsibility should be encouraged, rewards based on results, and a climate of trust and open communication should prevail.

  3. Assessing excellence in translational cancer research: a consensus based framework

    PubMed Central

    2013-01-01

    Background It takes several years on average to translate basic research findings into clinical research and eventually deliver patient benefits. An expert-based excellence assessment can help improve this process by: identifying high performing Comprehensive Cancer Centres; best practices in translational cancer research; improving the quality and efficiency of the translational cancer research process. This can help build networks of excellent Centres by aiding focused partnerships. In this paper we report on a consensus building exercise that was undertaken to construct an excellence assessment framework for translational cancer research in Europe. Methods We used mixed methods to reach consensus: a systematic review of existing translational research models critically appraised for suitability in performance assessment of Cancer Centres; a survey among European stakeholders (researchers, clinicians, patient representatives and managers) to score a list of potential excellence criteria, a focus group with selected representatives of survey participants to review and rescore the excellence criteria; an expert group meeting to refine the list; an open validation round with stakeholders and a critical review of the emerging framework by an independent body: a committee formed by the European Academy of Cancer Sciences. Results The resulting excellence assessment framework has 18 criteria categorized in 6 themes. Each criterion has a number of questions/sub-criteria. Stakeholders favoured using qualitative excellence criteria to evaluate the translational research “process” rather than quantitative criteria or judging only the outputs. Examples of criteria include checking if the Centre has mechanisms that can be rated as excellent for: involvement of basic researchers and clinicians in translational research (quality of supervision and incentives provided to clinicians to do a PhD in translational research) and well designed clinical trials based on ground-breaking concepts (innovative patient stratification, substantial fraction of phase I/II trials, investigator-initiated trials). Critically, the framework supports reduced bureaucracy by building on existing European evaluation systems. Conclusions The excellence framework is the product of an intense stakeholder consensus building exercise. It will be piloted during an expert peer review/site visit of at least three European Comprehensive Cancer Centres. The findings regarding content, governance and implementation can have relevance for other clinical and research fields. PMID:24168073

    Strauss, Karl F.; Goullioud, Renaud; Cox, Brian; Grimes, James M.

    2011-01-01

    The design process often involves the use of Excel files during project development. To facilitate communications of the information in the Excel files, drawings are often generated. During the design process, the Excel files are updated often to reflect new input. The problem is that the drawings often lag the updates, often leading to confusion of the current state of the design. The use of this program allows visualization of complex data in a format that is more easily understandable than pages of numbers. Because the graphical output can be updated automatically, the manual labor of diagram drawing can be eliminated. The more frequent update of system diagrams can reduce confusion and reduce errors and is likely to uncover symmetric problems earlier in the design cycle, thus reducing rework and redesign.

  10. Predictors of excellent functional outcome in aneurysmal subarachnoid hemorrhage.

    PubMed

    Pegoli, Marianna; Mandrekar, Jay; Rabinstein, Alejandro A; Lanzino, Giuseppe

    2015-02-01

    OBJECT Case fatality rates after aneurysmal subarachnoid hemorrhage (aSAH) have decreased over time, and many patients treated with modern paradigms return to a normal life. However, there is little information on predictors of excellent functional outcome after aSAH. In this study, the authors investigated predictors of excellent outcome in a modern consecutive series of patients with aSAH. METHODS A retrospective review was conducted of patients with aSAH admitted between 2001 and 2013. The primary outcome measure was excellent functional outcome, defined as modified Rankin Scale (mRS) score of 0 or 1 at last follow-up within 1 year of aSAH. RESULTS Three hundred seventy-three patients were identified with posthospital follow-up. Excellent outcome was noted in 236 patients (63.3%), including an mRS score of 0 in 122 (32.7%) and an mRS score of 1 in 114 (30.6%). On univariate analysis, the following factors were associated with an excellent outcome: indicators of less severe bleeding, such as better World Federation of Neurosurgical Societies grade at any of the times of assessment, better modified Fisher grade, and absence of intracerebral hemorrhage (ICH), intraventricular hemorrhage (IVH), and symptomatic hydrocephalus; aneurysm treatment with coil embolization; absence of symptomatic vasospasm, delayed cerebral ischemia, and radiological infarction; absence of in-hospital seizures; lack of need for CSF diversion; fewer hours with fever; less severe anemia; and absence of transfusion. On multivariable analysis, the 4 variables that were most strongly associated with excellent outcome were presence of good clinical grade after neurological resuscitation, absence of ICH on initial CT scan, blood transfusion during the hospitalization, and radiological infarctions on final brain imaging. CONCLUSIONS Excellent outcomes (mRS score 0-1) can be achieved in the majority of patients with aSAH. The likelihood of excellent outcome is predicted by good clinical condition after resuscitation, absence of ICH on presentation, no evidence of infarction on brain imaging, and absence of blood transfusion during hospitalization.

  13. LICSS - a chemical spreadsheet in microsoft excel

    PubMed Central

    2012-01-01

    Background Representations of chemical datasets in spreadsheet format are important for ready data assimilation and manipulation. In addition to the normal spreadsheet facilities, chemical spreadsheets need to have visualisable chemical structures and data searchable by chemical as well as textual queries. Many such chemical spreadsheet tools are available, some operating in the familiar Microsoft Excel environment. However, within this group, the performance of Excel is often compromised, particularly in terms of the number of compounds which can usefully be stored on a sheet. Summary LICSS is a lightweight chemical spreadsheet within Microsoft Excel for Windows. LICSS stores structures solely as Smiles strings. Chemical operations are carried out by calling Java code modules which use the CDK, JChemPaint and OPSIN libraries to provide cheminformatics functionality. Compounds in sheets or charts may be visualised (individually or en masse), and sheets may be searched by substructure or similarity. All the molecular descriptors available in CDK may be calculated for compounds (in batch or on-the-fly), and various cheminformatic operations such as fingerprint calculation, Sammon mapping, clustering and R group table creation may be carried out. We detail here the features of LICSS and how they are implemented. We also explain the design criteria, particularly in terms of potential corporate use, which led to this particular implementation. Conclusions LICSS is an Excel-based chemical spreadsheet with a difference: • It can usefully be used on sheets containing hundreds of thousands of compounds; it doesn't compromise the normal performance of Microsoft Excel • It is designed to be installed and run in environments in which users do not have admin privileges; installation involves merely file copying, and sharing of LICSS sheets invokes automatic installation • It is free and extensible LICSS is open source software and we hope sufficient detail is provided here to enable developers to add their own features and share with the community.

    Objective: To better understand the implications of inadequately recognizing clinical excellence in academia by exploring the perspectives of clinically excellent faculty within prominent American departments of medicine. Design: Qualitative study. Setting: 8 academic institutions. Participants: 24 clinically excellent department of medicine physicians. Methods: Between March 1 and May 31, 2007, investigators conducted in-depth semi-structured interviews with 24 clinically excellent physicians at leading academic institutions. Interview transcripts were independently coded by two investigators and compared for agreement. Content analysis identified themes related to clinical excellence in academia. Results: Twenty informants (83%) were Associate Professors or Professors, 8 (33%) were females, and the physicians hailed from a wide range of internal medicine specialties. The mean percent effort spent in clinical care by the physicians was 48%. The five domains that emerged related to academic medicine’s failure to recognize clinical excellence were: (1) low morale and prestige among clinicians, (2) less than excellent patient care, (3) loss of talented clinicians, (4) a lack of commitment to improve patient care systems, and (5) fewer excellent clinician role models to inspire trainees. Conclusions: If academic medical centers fail to recognize clinical excellence among its physicians, they may be doing a disservice to the patients that they pledge to serve. It is hoped that initiatives aiming to measure clinical performance in our academic medical centers will translate into meaningful recognition for those achieving excellence such that outstanding clinicians may feel valued and decide to stay in academia.

    To meet the challenge of technical excellence, AIA established a rocket propulsion committee to develop the National Rocket Propulsion Strategic Plan. Developing such a plan required a broad spectrum of experience and disciplines. The Strategic Plan team needed the participation of industry, government, and academia. The plan provides, if followed, a means for the U.S. to maintain technical excellence and world leadership in rocket propulsion. To implement the National Rocket Propulsion Strategic Plan is to invest in the social, economic, and technological futures of America. The plan lays the basis for upgrading existing propulsion systems and a firm base for future full scale development, production, and operation of rocket propulsion systems for space, defense, and commercial applications.

    2014-11-01

    This work focuses on rock-inhabiting fungi (RIF) of Antarctic rocky deserts, considered the closest to a possible Martian habitat, as the best example of adaptation to the extremes. The study of RIF ecophysiology, resistance and adaptation provides tools that shed light on the evolution of extremophily. These studies also help define the actual limits for life and provide insight for investigating its existence beyond our planet. The scientific results obtained from over 20 years of research on the biodiversity, phylogeny and evolution toward extremotolerance reviewed here demonstrate how these fascinating organisms can withstand conditions well beyond those in their natural environment. A final focus is given on results and perspectives arising from a recent proteomic approach, and from astrobiological experiments and their significance for future space exploration. These studies demonstrate that Antarctic RIF offer an excellent opportunity to investigate many basic, but also applicative areas of research on extremophily. PMID:25381156

    Criteria for defining errors of a physical theory are formulated. It is shown that the Special Theory of Relativity (STR) has a solid mathematical basis. An enormous amount of experiments carried out in particle physics use beams of particles having a very high energy. The data of these experiments are consistent with STR and support our confidence that STR is an excellent theory. Several specific cases of this issue are discussed explicitly. Contrary to a common belief, it is proved that the contemporary mainstream of physicists adhere to some theoretical ideas that violate STR.

    2015-03-01

    Lignin, the main natural aromatic polymer was always aroused researchers interest. Currently around 90% of this biomaterial is burned for energy. It has a very complex and complicated structure which depends on the separation method and plant species, what determine difficulties to use as a raw material widely. This research presents a physical method to modify lignin by ultrasonic irradiation in order to obtain nanoparticles. The nanoparticles synthesized were dimensionally and morphologically characterized. At the same time the preoccupations were to determine the structural and compositional changes that occurred after sonication. To achieve this, two types of commercial lignins (wheat straw and Sarkanda grass) were used and the modifications were analyzed by FTIR-spectroscopy, GPC-chromatography, (31)P-NMR-spectroscopy and HSQC0. The results confirm that the compositional and structural changes of nanoparticles obtained are not significantly modified at the intensity applied but depend on the nature of lignin. PMID:25218770

    This Center-of-Excellence grant has supported the development of an imaging system based on microlaser arrays. In the second year of the grant, we dealt with the slow delivery of new microlaser arrays by developing a new approach to the idea of all-solid-state confocal microscopy. One solution was moderately successful, and the other has produced the first microscope that is electronically switchable from confocal to non-confocal. We think this may be a useful alternative to the final design. This report thus discloses patentable material. We describe first the central Microlaser Microscope project, then we will touch briefly on the other projects of the Center. The publications are primarily those of the smaller projects, though no longer exclusively so. The appendix includes some of the publications.

    2014-06-01

    Co3O4 nanorods and nanobelts can be synthesized controllably by a template-free hydrothermal method. Enhanced lithium-ion battery performances are obtained from Co3O4 nanorods and nanobelts. After 50 cycles, the reversible capacity is up to 1124 and 1260 mAh g-1 at C/20 rate (20 h per half cycle), respectively, and the cyclability are excellent. Lithium-ion battery performance of nanobelts is much higher than that of nanorods. Such a behavior is attributed to more efficient Li insertion, less volume change and no agglomeration of nanobelts. The present results open a way for fabrication of porous 1D nanostructures and imply that porous 1D nanostructures are good candidates for high performance lithium-ion battery anodes.

    2014-01-01

    Endoscopic submucosal dissection (ESD) has important advantages over endoscopic mucosal resection (EMR) for early gastrointestinal neoplasia treatment, but its difficult learning curve and associated risks have constrained its wider expansion. ESD training includes a comprehensive study of ESD basics, attending live cases and performing initial interventions in animal models, ideally under expert supervision. Mentoring methods in Japan and other Asian countries are reviewed, with a special concern in the conditions recommended for trainees to engage in an ESD program and achieve competence. Animal training is usually based on the well-known porcine model. Ex vivo models for esophageal, gastric and rectal ESD are cheap and easy to set up, whereas in vivo training requires special settings and veterinarian support. Nevertheless, it is advisable to gain experience in the live pig, with conditions that are similar to humans, before moving on to real patients. Particular attention is focused on colorectal ESD (CR-ESD), one of the most difficult locations for this technique. Since most of the potential lesions for ESD in Western countries are located in the colon or rectum, excellence in training is of paramount importance for successful outcomes in CR-ESD in the West.

    Wind tunnel investigations were conducted on an 0.010-scale representation of the VL70-000140C Integrated Space Shuttle Launch Vehicle. The primary test objective was to obtain Reynolds number effects on orbiter elevon hinge moments and wing bending/torsional moments. Launch vehicle aerodynamic force data were also recorded. The elevon hinge moments, wing bending/torsional moments, and vehicle force data were recorded over an angle of attack range of -6 deg to +6 deg, an angle of sideslip range of -6 deg to +6 deg, at Mach numbers of 0.6, 0.975, 1.05 and 1.25. The Reynolds number was varied from a minimum of 4.5 million/foot to a maximum of 11.5 million/foot. The complete integrated configuration was tested with the orbiter elevons set at 0 deg and deflected to 9 deg on the outboard elevon and 10 deg on the inboard elevon. Testing was conducted in the TWT 19.7% porous transonic test section with the model sting mounted through the orbiter base. All aerodynamic force data were obtained from internal strain gage balance located in the orbiter.

    1990-01-01

    Tests with specially instrumented NASA Boeing 737 and 727 aircraft together with several different ground friction measuring devices were conducted for a variety of runway surface types and conditions. These tests are part of joint FAA/NASA Aircraft/Ground Vehicle Runway Friction Program aimed at obtaining a better understanding of aircraft ground handling performance under adverse weather conditions and defining relationships between aircraft and ground vehicle tire friction measurements. Aircraft braking performance on dry, wet, snow and ice-covered runway conditions is discussed as well as ground vehicle friction data obtained under similar runway conditions. For a given contaminated runway surface condition, the correlation between ground vehicles and aircraft friction data is identified. The influence of major test parameters on friction measurements such as speed, test tire characteristics, type and amount of surface contaminant, and ambient temperature are discussed. The effect of surface type on wet friction levels is also evaluated from comparative data collected on grooved and ungrooved concrete and asphalt surfaces.

    Hayes, Sherrill H

    2010-01-01

    Historically, invited lecturers have often challenged us to define excel lence in physical therapy practice, or in our academic programs. While some have addressed different char acteristics of excellence, our profession has not really come together to address 2 very important questions: what does “quality” mean in physical therapist education? And how do we measure it? Using 3 elements of Friendship, Leadership, and Mentoring, and Defining Excellence and juxtaposing these with Linda Crane and her life, a vision of excellence in physical therapy educational programs was explored in this invited lecture. The text of that lecture ensues. PMID:20520760

    Graphene has evoked extensive interests for its abundant physical properties and potential applications. It is reported that the interfacial electronic interaction between metal and graphene would give rise to charge transfer and change the electronic properties of graphene, leading to some novel electrical and magnetic properties in metal-graphene heterostructure. In addition, large specific surface area, low density and high chemical stability make graphene act as an ideal coating material. Taking full advantage of the aforementioned features of graphene, we synthesized graphene-coated Fe nanocomposites for the first time and investigated their microwave absorption properties. Due to the charge transfer at Fe-graphene interface in Fe/G, the nanocomposites show distinct dielectric properties, which result in excellent microwave absorption performance in a wide frequency range. This work provides a novel approach for exploring high-performance microwave absorption material as well as expands the application field of graphene-based materials. PMID:24305606

    2014-11-27

    As part of the intercomparison on the measurement of personal dose equivalent Hp(10), jointly organised by the International Atomic Energy Agency and the Algerian Secondary Standard Dosimetry Laboratory, for the African region, up to 12 dosemeters were added to the packages of the 28 participants to evaluate the background and transport dose (BGTD), received by the dosemeters before and after their irradiation at the SSDL (environmental irradiations, scanning process at the airports, etc.). Out of the 28 participants, only 17 reported the corresponding BGTD measured values, which lied between 0.03 and 0.8 mSv. The mean measured value of BG was (0.25±0.14) mSv, which is significantly high compared with the lowest dose value used in the intercomparison exercise. The BGTD correction shifted the overall results of the intercomparison from an overestimation of dose (?8 % before applying BGT dose correction) to an underestimation of dose (-9 % after correction). The measurement protocol and the detailed analysis of the results and applied corrections are discussed in this paper. PMID:25433048

    Acoustic pollution is an environmental problem that is becoming increasingly more important in our society. Likewise, the accumulation of generated waste and the need for waste management are also becoming more and more pressing. In this study we describe a new material--called PROUSO--obtained from industrial wastes. PROUSO has a variety of commercial and engineering, as well as building, applications. The main raw materials used for this environmentally friendly material come from slag from the aluminium recycling process, dust from the marble industry, foundry sands, and recycled expanded polystyrene from recycled packaging. Some natural materials, such as plastic clays, are also used. To obtain PROUSO we used a conventional ceramic process, forming new mineral phases and incorporating polluted elements into the structure. Its physical properties make PROUSO an excellent acoustic and thermal insulation material. It absorbs 95% of the sound in the frequency band of the 500 Hz. Its compressive strength makes it ideal for use in ceramic wall building. PMID:18514765

  6. Torsional Angle Driver (TorAD) System for HyperChem/Excel

    NASA Astrophysics Data System (ADS)

    Starkey, Ronald

    1999-02-01

    The torsional angle driver system for HyperChem/Excel is a package of several Excel spreadsheets and macro programs to be used with HyperChem to obtain and plot information, such as total energy, for the conformations that result from a 360° rotation about a torsional angle system in a molecule. The TorAD system also includes several HyperChem scripts to facilitate its use. TorAD was developed for use in the undergraduate organic chemistry laboratory. The results obtained with TorAD could be obtained manually with HyperChem, but it would take considerable time and would not be instructive to the students. Use of the TorAD system allows students to spend their time on the more important aspect of conformation analysisinterpretation of results. The Excel spreadsheet/macro programs in TorAD include:

    · Tor_xl_a and tor_xl obtain and plot the total energy at 5° torsional-angle intervals. The calculation method, the torsional-angle restraint, and the structure to be used at each angle can be set by the user. The advanced version, tor_xl_a, which requires HyperChem 4.5 or later, also allows torsional-angle structures to be saved for later recall as individual structures or, using a HyperChem script, in a movie format. It also provides a rapid scan of the 360° rotation where only single-point calculations, rather than geometry optimizations, are performed. The tor_xl system will perform routine tasks in a manner suitable for most instructional settings. · Tor_Comp performs molecular mechanics optimizations at 5° intervals and obtains and plots four energy parameters (total, torsional, nonbonded, and bond [bend plus stretch] energy) as a function of torsional angle. The calculation method and the restraint can be specified. · TorDipol produces a plot of the total energy and the calculated dipole moment at 5° steps of the torsional angle. The default calculation is the semi-empirical AM1 method, but other methods can be used. The calculation method and the restraint can be specified. · Tor2_180 and Tor2_360 rotate two torsional angles to provide a 3D plot of the resulting total energy surface. Tor2_180 performs a 0 to 180° rotation, in 10° steps, on each of the two torsional angle systems (tor1 and tor2) selected. Tor2_360 will do a -180° to +180° (360° total) rotation of the two torsional angles in 20° steps.
    Both tor2_180 and tor2_360 provide an x, y, z plot (x = angle 1, y = angle 2, z = energy) and a topo plot (x = angle 1, y = angle 2, z = topo lines and color coding). The molecular mechanics method and the restraint can be specified. Hardware and Software Requirement Hardware and software requirements for Torsional Angle Driver (TorAD) are shown in Table 1. These programs require a version of HyperChem 4.0 or later that supports DDE. Also required is Microsoft Excel 5.0 or higher. HyperChem and Excel are not included with the issue.

    'Ilogen-Excel', an Ayurvedic herbal formulation is composed of eight medicinal plants (Curcuma longa, Strychnos potatorum, Salacia oblonga, Tinospora cordifolia, Vetivelia zizanioides, Coscinium fenestratum, Andrographis paniculata and Mimosa pudica). The present study evaluates the antihyperglycemic effect of 'Ilogen-Excel' in streptozotocin induced diabetic rats. Rats were rendered diabetic by streptozotocin (STZ) (45 mg/kg body weight). Oral administration of 'Ilogen-Excel' (50 mg/kg and 100 mg/kg) for 60 days resulted in significantly lowered levels of blood glucose and significantly increased levels of plasma insulin, hepatic glycogen and total hemoglobin. 'Ilogen-Excel' administration also decreased the levels of glycosylated hemoglobin, plasma thiobarbituric acid reactive substances, hydroperoxides, ceruloplasmin and vitamin E in diabetic rats. Plasma reduced glutathione and vitamin C were significantly elevated by oral administration of 'Ilogen-Excel'. Administration of insulin normalized all the biochemical parameters studied in diabetic rats. The effect at a dose of 100 mg/kg was more pronounced than 50 mg/kg and brought back all the parameters to near normal levels. Thus, our study shows the antihyperglycemic effects of 'Ilogen-Excel' in STZ-induced diabetic rats. Our study also shows that combined therapy is better than individual therapy. PMID:17665851

  10. Mercapturic acids of styrene in man: comparability of the results obtained by LC/MS/MS and by HPLC-fluorimeter, and stability of samples under different storage conditions.

    2006-04-10

    Two analytical methods (HPLC-fluorimeter [HPLC-FLD] and tandem mass spectrometry LC/MS/MS) are available to assay phenyl-hydroxyethylmercapturic acids (PHEMAs), the mercapturic acids of styrene in humans. In the past, each method was used to check different populations of subjects, but until now no attempt has been made to compare the two methods. This study was designed to verify whether the two methods actually give comparable results. The influence of different conditions of sample storage in altering the concentration of PHEMAs was also investigated. Urine samples were collected at the beginning and at the end of the workshift from 10 workers exposed to different levels of styrene. Each sample was analysed both by LC/MS/MS after storage under different conditions (respectively, at -20 and +4 degrees C, and after repeated freezing-thawing cycles), and by HPLC-FLD (in the same conditions of storage). Strong correlations were found between the two methods both for total PHEMAs and for each of the isomers measured, including the minor (S,R)-M1. Also an alternative approach, the Bland-Altman test, confirmed the agreement between the two methods. The different storage conditions tested did not decrease the concentration of PHEMAs but, surprisingly, a clear trend to increase was shown, particularly for (R,R)-M1, (S,R)-M2 and (R,R)-M2 in samples stored at +4 degrees C for 1 week. In conclusion, the study demonstrates that the methods give comparable results. Indirectly, this confirms also the main characteristics of PHEMAs, showed in the previous experiments: low biotransformation rates of styrene into PHEMAs; large inter-individual variability; and the presence of a clear preference in the excretion of the isomers deriving from (S)-styrene oxide. PHEMAs appear stable under different storage conditions, but further studies are needed to explain the increase of levels that occurs when samples are not kept frozen. To avoid pre-analytical errors, samples collected for biomonitoring or research purposes should be frozen as soon as possible, and thawed only one time just before the analysis. PMID:16242871

    The establishment of the DOE-EM Dr. Samuel P. Massie Chair of Excellence provides an excellent opportunity for Hampton University to be involved in key environmental issues in the 21st Century. The main areas of focus are on: 1. Coal gasification with respect to pollution prevention and reduction. 2. Solid waste treatment through bioremediation technology and 3. Industrial wastewater treatment Synthesizing ion catalysts suitable for use in slurry bubble column reaction was carried out. Construction of an autoclave continuous stirred tank reactor has been completed. At the initial stage of the development of this program, work was conducted in the area of formic acid recovery from waste streams, which yielded useful results. We also succeeded in the removal of priority metal ions such as cadmium, chromium, copper, lead, mercury, nickel, silver, thallium, zinc, etc., from industrial and municipal wastewater by using natural wastes. The process uses tree leaves to adsorb the metal ions in the wastewater. The ultimate goal is to develop inexpensive, highly available, effective metal ion adsorbents from natural wastes as an alternative to existing commercial adsorbents, and also to explain the possible adsorption mechanism that is taking place. This technology uses natural wastes to eliminate other wastes. Obviously, there are several advantages: (1) the negative impact on environment is eliminated, (2) the complicated regeneration step is not needed, and (3) the procedure saves money and energy. Twelve different types of leaves have been tested with lead, zinc, and nickel. The study mechanism showed that the leaf tannin is an active ingredient in the adsorption of metal ions. The ion-exchange mechanism controlled the adsorption process.

    Notre Dame of Maryland University (NDMU) has an NSF S-STEM grant, Pathways to Excellence, that gives 10 scholarships annually to academically talented women undergraduates with demonstrated financial need who are pursuing degrees in mathematics, physics, computer information systems, or engineering. NDMU has been cited (Whitten, et al. (2007)) as providing a female friendly environment for the study of physics. In this program we are using a tri-part mentoring system involving a faculty member in the student's discipline, a peer mentor from the program and an external alumnae mentor. The program also has a thematic seminar course for the scholars. Each student in the program is tasked to construct a career development plan in assistance with her faculty mentor and set measured annual goals. In addition, all scholarship students are requested to have an experiential experience. As a result, NDMU aims to strengthen its role in increasing the numbers of well-educated and skilled women employees from diverse backgrounds, including mostly first-generation college students, in technical and scientific areas. Early assessment of the success of the program will be presented as well as modifications that resulted from the formative evaluation.

    Marino, Dale J

    2005-01-01

    Abstract Physiologically based pharmacokinetic (PBPK) models are mathematical descriptions depicting the relationship between external exposure and internal dose. These models have found great utility for interspecies extrapolation. However, specialized computer software packages, which are not widely distributed, have typically been used for model development and utilization. A few physiological models have been reported using more widely available software packages (e.g., Microsoft Excel), but these tend to include less complex processes and dose metrics. To ascertain the capability of Microsoft Excel and Visual Basis for Applications (VBA) for PBPK modeling, models for styrene, vinyl chloride, and methylene chloride were coded in Advanced Continuous Simulation Language (ACSL), Excel, and VBA, and simulation results were compared. For styrene, differences between ACSL and Excel or VBA compartment concentrations and rates of change were less than +/-7.5E-10 using the same numerical integration technique and time step. Differences using VBA fixed step or ACSL Gear's methods were generally <1.00E-03, although larger differences involving very small values were noted after exposure transitions. For vinyl chloride and methylene chloride, Excel and VBA PBPK model dose metrics differed by no more than -0.013% or -0.23%, respectively, from ACSL results. These differences are likely attributable to different step sizes rather than different numerical integration techniques. These results indicate that Microsoft Excel and VBA can be useful tools for utilizing PBPK models, and given the availability of these software programs, it is hoped that this effort will help facilitate the use and investigation of PBPK modeling.

    This study aims to understand the relationship between participating nurses' motivation, achievement and satisfaction before and after they learned to program in Excel Visual Basic for Applications (Excel VBA). We held a workshop to train nurses in developing simple Excel VBA information systems to support their clinical or administrative practices. Before and after the workshop, the participants were evaluated on their knowledge of Excel VBA, and a questionnaire was given to survey their learning motivation and satisfaction. Statistics softwares Winsteps and SPSS were used for data analysis. Results show that the participants are more knowledgeable about VBA as well as more motivated in learning VBA after the workshop. Participants were highly satisfied with the overall arrangement of the workshop and instructors, but didn't have enough confidence in promoting the application of Excel VBA themselves. In addition, we were unable to predict the participants' achievement by their demographic characteristics or pre-test motivation level. PMID:24943568

    Double-shelled hollow carbon spheres with reduced graphene oxide (RGO) as inner shell and carbon (C) layer as outer shell have been successfully designed and prepared. This tailor-making structure acts as an excellent capsule for encapsulating with ultrafine Pd nanoparticles (Pd NPs), which could effectively prevent Pd NPs from aggregation and leaching. As a result, the as-obtained RGO@Pd@C nanohybid exhibits superior and stable catalytic performance. With the aid of RGO@Pd@C, the reduction reaction of 4-nitrophenol (4-NP) to 4-aminophenol with NaBH4 as reducing agent can be finished within only 30?s, even the content of Pd is as low as 0.28 wt%. As far as we know, RGO@Pd@C is one of the most effective catalyst for 4-NP reducing reaction up to now. PMID:24514577

    2009-01-01

    Registered nurses make measurable contributions to the health and wellness of persons living in nursing homes. However, most nursing homes do not employ adequate numbers of professional nurses with specialized training in the nursing care of older adults to positively impact resident outcomes. As a result, many people never receive excellent geriatric nursing while living in a long-term care facility. Nurses have introduced various professional practice models into health care institutions as tools for leading nursing practice, improving client outcomes, and achieving organizational goals. Problematically, few professional practice models have been implemented in nursing homes. This article introduces an evidence-based framework for professional nursing practice in long-term care. The Everyday Excellence framework is based upon eight guiding principles: Valuing, Envisioning, Peopling, Securing, Learning, Empowering, Leading, and Advancing Excellence. Future research will evaluate the usefulness of this framework for professional nursing practice. PMID:20077966

    Purpose of the Study: This article describes the successful evolution of a state coalition for nursing home excellence that brought together organizations that had once worked in silos to improve the quality of care through the implementation of culture change for Arkansas’ 240 nursing homes with 27,700 residents. Design and Methods: The Coalition was established in 2004 when stakeholders were invited to participate in a retreat to explore how they could come together with a common goal to improve the care of older Arkansans. These stakeholders were encouraged to bring their organization’s perspectives to the Coalition and determine ways to work with others. The continuous refinement of the Coalition’s activities involved revisiting goals of the Coalition, assessing the need for other stakeholders, identifying gaps and overlaps in quality and culture change programming, and providing feedback to Coalition members. Results: The Coalition stakeholders had the leadership to articulate and mobilize others around a common vision of improving quality of care in nursing homes through culture change. Over time, the Coalition members developed a willingness to share resources and to speak as one voice. Implications: Stakeholders from diverse organizations and governing bodies can come together to complement each other’s work and collaborate on programs to build a better system of care for the frail and elderly persons across a state. The success of this statewide effort lends support for policies that encourage regional coalitions of providers to improve care. PMID:24443610

    The Essential Principles of Climate Sciences (http://www.climatescience.gov/Library/Literacy/) provides a coherent framework for climate education, but educators need professional development and standards-aligned curriculum to implement it. Climate literacy efforts at CIRES range from professional development for teachers, scientists and communicators to online courses and curriculum development. The NASA-funded Inspiring Climate Education Excellence (ICEE) project is a professional development project for secondary science educators, incorporating face to face workshops, an online course and self-directed learning modules for teachers. Focusing on changes in Arctic ice and sea level rise, the modules use NASA resources for professional development around key guiding questions, and build content knowledge and pedagogical skills for how to teach climate science. The resources are being developed in partnership with GLOBE, the National Science Digital Library (NSDL) and the University of Colorado, Boulder Independent Learning Program. This presentation describes ICEE and other CIRES climate literacy projects, and describes results from a recent CIRES survey of US teachers on their climate education needs, practices and knowledge of climate literacy topics.

    Context. Dome Fuji, the second highest region on the Antarctic plateau, is expected to have some of the best astronomical seeing on Earth. However, site testing at Dome Fuji is still in its very early stages. Aims. To investigate the astronomical seeing in the free atmosphere above Dome Fuji, and to determine the height of the surface boundary layer. Methods. A Differential Image Motion Monitor was used to measure the seeing in the visible (472 nm) at a height of 11 m above the snow surface at Dome Fuji during the austral summer of 2012/2013. Results. Seeing below 0.2'' has been observed. The seeing often has a local minimum of ~0.3'' near 18 h local time. Some periods of excellent seeing, 0.3'' or smaller, were also observed, sometimes extending for several hours at local midnight. The median seeing is higher, at 0.52''---this large value is believed to be caused by periods when the telescope was within the turbulent boundary layer. Conclusions. The diurnal variation of the daytime seeing at Dome Fuji is sim...

    Nurse leaders call for a more diverse nursing workforce, but too few address the concept of inclusion as a recruitment and retention strategy or as part of improving the academic learning milieu. This article addresses organizational considerations of diversity and inclusion as part of the agenda established by the Association of American Colleges and Universities for inclusive excellence, building on the idea that academic environments only become excellent when an inclusive climate is reached. Six organizational strategies to inclusion are presented from the authors' experiences, some structural and others behavioral: admissions processes, invisibility, absence of community, promotion and tenure, exclusion, and tokenism. A call for structural and behavioral adaptions within nursing education to advance an inclusive excellence agenda is presented. PMID:25839947

    Well-ordered organic-inorganic hybrid layered manganese oxide nanocomposites (CTAB-Al-MO) with excellent decolorization performance were prepared through a two-step process. Specifically, the MnO{sub 2} nanosheets were self-assembled in the presence of CTAB, and subsequently pillared with Keggin ions. The obtained CTAB-Al-MO with the basal spacing of 1.59 nm could be stable at 300 Degree-Sign C for 2 h and also possesses high total pore volumes (0.41 cm Superscript-Three g{sup -1}) and high specific BET surface area (161 m{sup 2} g{sup -1}), which is nine times larger than that of the pristine (19 m{sup 2} g{sup -1}). Possible formation process for the highly thermal stable CTAB-Al-MO is proposed here. The decolorization experiments of methyl orange showed that the obtained CTAB-Al-MO exhibit excellent performance in wastewater treatment and the decolorization rate could reach 95% within 5 min. - Graphical Abstract: Well-ordered organic-inorganic hybrid LMO nanocomposites (CTAB-Al-MO) with excellent decolorization performance were prepared through a two-step process.

  1. Rounbletz: An Excel-based software to perform cost-benefit analysis at local scale

    NASA Astrophysics Data System (ADS)

    Nicolet, Pierrick; Jaboyedoff, Michel; Lévy, Sébastien

    2014-05-01

    Public financial support for natural hazard protection measure is generally attributed, in Switzerland, according to the results of cost-benefit analysis. The analysis is generally made with a very controlled procedure, where many parameters are predefined according to a few input parameters. Vulnerability is, for example, defined according to the building's type and the hazard's type and intensity (divided in 4 classes). Therefore, this procedure, although having the advantage of being reproducible, suffers from a lack of ability to describe the local specificities. This work describes an Excel-based application which allows to calculate the cost-benefit analysis at local scale, based on the usual 3 scenarios and the predefined intensities used in Switzerland. Although the risk equations are not new, this study focuses on finding the right balance between a rigid but reproducible, and a free but too much user-dependent approach. Many parameters value are therefore predefined, but are displayed and can be modified by the user if needed. If these predefined parameters are modified, the program highlights them in the output in order to be transparent for the person who will take a decision based on these results. The software is multi-hazard, but is not yet designed to account for the possible hazards interactions. A preliminary attempt to include the uncertainty in the calculation is also presented. The uncertainty analysis consists of using triangular distributions for the input parameters and performing a Monte-Carlo simulation to obtain a distribution of possible values. The triangular distribution is chosen because of its simplicity, which is a desirable characteristic since the specialist assessing the risk is most of the time more comfortable with the natural phenomenon than with probabilities. Thus, since this type of analysis always suffers from a high uncertainty, this simple procedure allows taking this uncertainty into account for the decision process.

    2015-02-01

    Excellent initial guess functions for shooting method, providing for setting suitable initial estimates, are developed to solve multipoint pumping high power Yb3+-doped fiber lasers (YDFLs) model with boundary conditions. Simulation results show that shooting method with excellent initial guess functions can get rapidly the exact values of YDFLs after less than five iteration times. In excellent initial guess functions for signal power and pump power of 3-point pumping or 4-point pumping YDFLs, the guess value of conversion efficiency is greater than or equal to the critical guess value of conversion efficiency. The critical guess value of conversion efficiency is less than 0.21 for all the fiber length in three-point pumping or four-point pumping YDFLs. Comparing to number sequence transition method based on MATLAB BVP solvers of bvp4c(NSTM-bvp4c) and shooting method with answer ranges definition, the simple shooting method with excellent initial guess functions is more reliable and faster for multipoint pumping YDFLs.

  1. MELTS_Excel: A Microsoft Excel-based MELTS interface for research and teaching of magma properties and evolution

    NASA Astrophysics Data System (ADS)

    Gualda, Guilherme A. R.; Ghiorso, Mark S.

    2015-01-01

    thermodynamic modeling software MELTS is a powerful tool for investigating crystallization and melting in natural magmatic systems. Rhyolite-MELTS is a recalibration of MELTS that better captures the evolution of silicic magmas in the upper crust. The current interface of rhyolite-MELTS, while flexible, can be somewhat cumbersome for the novice. We present a new interface that uses web services consumed by a VBA backend in Microsoft Excel©. The interface is contained within a macro-enabled workbook, where the user can insert the model input information and initiate computations that are executed on a central server at OFM Research. Results of simple calculations are shown immediately within the interface itself. It is also possible to combine a sequence of calculations into an evolutionary path; the user can input starting and ending temperatures and pressures, temperature and pressure steps, and the prevailing oxidation conditions. The program shows partial updates at every step of the computations; at the conclusion of the calculations, a series of data sheets and diagrams are created in a separate workbook, which can be saved independently of the interface. Additionally, the user can specify a grid of temperatures and pressures and calculate a phase diagram showing the conditions at which different phases are present. The interface can be used to apply the rhyolite-MELTS geobarometer. We demonstrate applications of the interface using an example early-erupted Bishop Tuff composition. The interface is simple to use and flexible, but it requires an internet connection. The interface is distributed for free from http://melts.ofm-research.org.

    The culture of endothelial progenitor cells (EPC) provides an excellent tool to research on EPC biology and vascular regeneration and vasculogenesis. The use of different protocols to obtain EPC cultures makes it difficult to obtain comparable results in different groups. This work offers a systematic comparison of the main variables of most commonly used protocols for EPC isolation, culture and functional evaluation. Peripheral blood samples from healthy individuals were recovered and mononuclear cells were cultured. Different recovery and culture conditions were tested: blood volume, blood anticoagulant, coating matrix and percentage of foetal bovine serum (FBS) in culture media. The success of culture procedure, first colonies of endothelial cells appearance time, correlation with number of circulating EPC (cEPC) and functional comparison with human umbilical vein endothelial cells (HUVEC) were studied. The use of heparin, a minimum blood volume of 30 ml, fibronectin as a coating matrix and endothelial growing media-2 supplemented with 20% FBS increased the success of obtaining EPC cultures up to 80% of the processed samples while reducing EPC colony appearance mean time to a minimum of 13 days. Blood samples exhibiting higher cEPC numbers resulted in reduced EPC colony appearance mean time. Cells isolated by using this combination were endothelial cell-like EPCs morphological and phenotypically. Functionally, cultured EPC showed decreased growing and vasculogenic capacity when compared to HUVEC. Thus, above-mentioned conditions allow the isolation and culture of EPC with smaller blood volumes and shorter times than currently used protocols. PMID:24118735

    An electric conductive Ni silicide nanowire (NiSi NW) embedding electric force microscopy (EFM) tip was fabricated by the dielectrophoretic method and was used to obtain electric information. Due to the geometric and electric excellence, the NiSi NW provides advantages in imaging and fabrication of the microscopy tip. A lead zirconate titanate (PZT) ferroelectric thin film was positively and negatively polarized, and the polarities were obtained by probing of the NiSi NW EFM tip to give distinctive charging information of the PZT film. Moreover, the NiSi NW EFM probing was adopted to achieve the electrical signal from the NW interconnect. The NiSi NW EFM probe confirmed the uniform electric-potential distribution through the NiSi NW interconnect with a small standard deviation. This demonstrates the feasibility of functional utilizations of the NiSi NW.

  1. Excel Heat Transfer Add-in for Engineering Courses

    NSDL National Science Digital Library

    Dent, Troy

    The application of computer software is central in modern engineering instruction. Software has been specifically designed for courses and some textbooks are packaged with specialized versions of popular software. However, a survey of University of Alabama alumni shows that the majority primarily uses MS Excel for engineering computations compared to those that commonly use engineering software packages. The wide availability of MS Excel contributes to its use. With this in mind, an Add-in for MS Excel is being developed to provide a useful package of engineering functions for heat transfer instruction. The initial Add-in was developed to calculate the dimensionless temperature for 1-D transient heat conduction in a solid. The Add-in includes 4 functions which handle a plane wall, infinite cylinder, sphere and semi-infinite solid. Additional modules have been developed to calculate the local or average Nusselt number for internal or external flows and the view factors for different 3-D radiation heat transfer setups. Currently, these three modules are presented separately as part of a Heat Transfer course, but could be combined into a single Add-in.

    A little stress or strain has been known to improve the performance of athletes, actors and of course nanomaterials alike. In fact strain in silicon is now a major engineering tool for improving the performance of devices, and is ubiquitously used in device design and fabrication. Strain engineering alters a material's band structure, a model of electron behaviour that describes how as atoms come together in a solid, their discrete electron orbitals overlap to ultimately give rise to bands of allowed energy levels. In a strained crystal lattice of silicon or silicon germanium the distance between atoms in the lattice is greater than usual and the bands of allowed energy levels change. This July marks 100 years since Bohr submitted his paper 'On the constitution of atoms and molecules' [1] where he describes the structure of the atom in terms of discrete allowed energy levels. The paper was a seminal contribution to the development of quantum mechanics and laid the initial theoretical precepts for band gap engineering in devices. In this issue Nrauda and a collaboration of researchers in Europe and Australia study the growth of defect-free SiGe islands on pre-patterned silicon [2]. They analyse the strain in the islands and determine at what point lattice dislocations set in with a view to informing implementation of strain engineering in devices. The effects of strain on band structure in silicon and germanium were already studied and reported in the 1950s [3, 4]. Since then the increasing focus on nanoscale materials and the hunger for control of electronic properties has prompted further study of strain effects. The increased surface area to volume ratio in nanostructures changes the strain behaviour with respect to bulk materials, and this can also be exploited for handling and fine tuning strain to manipulate material properties. It is perhaps no surprise that graphene, one of the most high-profile materials in current nanotechnology research, has attracted interest in strain studies as well. Researchers in China investigated the effects of tensile strain on the thermal conductivity of graphene nanoribbons. Tuning the thermal conductivity of nanomaterials is highly desirable to optimize their functionality [5]. Wei and colleagues use computer simulations based on reverse nonequilibrium molecular dynamics (RNEMD) to demonstrate what they describe as 'a strain-induced magic flexibility of thermal engineering for carbon-based nanostructures', which may provide a new approach for tailoring nanomaterial functionality. Despite the attractions of more recently discovered carbon nanomaterials silicon remains the bedrock of the semiconductor device industry. Germanium nanostructures also hold significant interest, such as Ge nanowires, which have high mobility and a conveniently low synthesis temperature [6]. In fact the potential applications of germanium nanowires in field effect transistors and nanobridge devices prompted Jagadish and colleagues in Australia, Korea and the UK to investigate the growth of taper-free kinked Ge nanowires in silicon [7]. As they point out many recent reports have highlighted such kinked nanowires as valuable components for novel nanodevices. The work reported by Hrauda and colleagues in this issue looks at the growth of germanium islands on a silicon substrate rather than nanowires [2]. They grow islands on pre-patterned silicon with different levels of Ge deposition with the aim of better understanding how to manage the effects of strain due to lattice mismatch between the two metals. Their results show that considerably more Ge can be deposited without dislocations forming than previously thought and reveal a distinctive cycle of changing island morphologies as Ge is deposited. They add, 'Strain relaxation is revealed to be the main driving force of a rather complex evolution of island shape and Ge distribution'. In reference to his theory of atoms Bohr is once said to have told Werner Heisenberg, 'We must be clear that when it comes to atoms, language can be used only as in poetry. The poet

    Patterns of acquisition of alcoholic beverages by underage youth were studied, using focus group methods with a sample of midwestern youth. Results showed that the alcohol initially used by those in their early teens is obtained from parents' stocks or from older siblings and friends. By the midteens, parties at which alcohol (usually beer) is readily available become the major source. In the mid to late teens, young people purchase alcohol from commercial alcohol outlets, despite the fact that 21 is the legal age for purchasing alcohol. Factors reported to increase the rate of successful alcohol purchases include female buyer, male seller, young seller, and convenience store outlet. Results of focus group interviews revealed the easy accessibility of alcoholic beverages to underage youth. Further investigation into patterns of underage access to alcohol is recommended, with results from the focus group study guiding the design of probability sample studies to assess their generalizability.

    Polymers have shown great promise in the design of high efficient and low cytotoxic gene vectors. Here we synthesize fluorinated dendrimers for use as gene vectors. Fluorinated dendrimers achieve excellent gene transfection efficacy in several cell lines (higher than 90% in HEK293 and HeLa cells) at extremely low N/P ratios. These polymers show superior efficacy and biocompatibility compared with several commercial transfection reagents such as Lipofectamine 2000 and SuperFect. Fluorination enhances the cellular uptake of the dendrimer/DNA polyplexes and facilitates their endosomal escape. In addition, the fluorinated dendrimer shows excellent serum resistance and exhibits high gene transfection efficacy even in medium containing 50% FBS. The results suggest that fluorinated dendrimers are a new class of highly efficient gene vectors and fluorination is a promising strategy to design gene vectors without involving sophisticated syntheses.

    At Hampden-Sydney College, we teach a one-semester introductory astronomy class targeting non-science majors. This course fulfills the laboratory science requirement, and as such the class is obligated to teach transferable skills such as basic numeracy, quantitative reasoning and data analysis. To this end, we explicitly teach the use of the most commonly available data analysis program, which is currently Microsoft Excel. The laboratory sciences are ideally suited to teaching these skills. During each laboratory session, students explore an astronomical phenomenon related to the lectures for that week. Randomly assigned partners use computers to analyze their data in spreadsheets and to write detailed reports structured like journal articles. We present nine Excel templates, along with the corresponding laboratory instructions, that are designed to teach general data analysis techniques using spreadsheets within the context of a traditional astronomy laboratory. These exercises begin with basic calculations and move toward more complex ones such as least squares fitting of sine functions and calculating distances from measured magnitudes and assumed luminosities.

    Laboratory Exercises with Excel Templates
    Measuring AnglesThis first lab uses the small angle formula.
    Jupiter's MoonsThe students take data with the CLEA lab of Jupiter's moons, but complete the data analysis using Excel. This includes least squares fitting of sine functions.
    Astrometry and ParallaxThe students complete the Astrometry of Asteroids CLEA lab, but perform the parallax calculations using Excel.
    The Resolution of a TelescopeThe students measure the resolution of their naked eyes and a telescope, using two eye charts, along with the theoretical resolution of the telescope for comparison.
    The Light Gathering Power of a TelescopeThe students observe a light bulb using a telescope equipped with a photometer and a mask of variable aperture.
    Solar RadiationThe students measure the length of a solar day and the transparency of the earth's atmosphere, using a sundial and a calorimeter.
    Binary StarsThe students use photodiodes and oscilloscopes to measure the light curve of a model eclipsing binary star.
    Distance and Age of the PleiadesThe students gather data using the CLEA lab of the same name, but they plot an HR diagram along with a distance dependent standard main sequence using Excel. This lab uses luminosities and the inverse square law, instead of absolute magnitudes and the distance modulus.

    Boron nitride nanotubes (BNNTs) are considered as a promising cold electron emission material owing to their negative electron affinity. BNNT field emitters show excellent oxidation endurance after high temperature thermal annealing of 600 °C in air ambient. There is no damage to the BNNTs after thermal annealing at a temperature of 600 °C and also no degradation of field emission properties. The thermally annealed BNNTs exhibit a high maximum emission current density of 8.39 mA/cm2 and show very robust emission stability. The BNNTs can be a promising emitter material for field emission devices under harsh oxygen environments.

  18. An Excel Workbook for Identifying Redox Processes in Ground Water

    2009-01-01

    The reduction/oxidation (redox) condition of ground water affects the concentration, transport, and fate of many anthropogenic and natural contaminants. The redox state of a ground-water sample is defined by the dominant type of reduction/oxidation reaction, or redox process, occurring in the sample, as inferred from water-quality data. However, because of the difficulty in defining and applying a systematic redox framework to samples from diverse hydrogeologic settings, many regional water-quality investigations do not attempt to determine the predominant redox process in ground water. Recently, McMahon and Chapelle (2008) devised a redox framework that was applied to a large number of samples from 15 principal aquifer systems in the United States to examine the effect of redox processes on water quality. This framework was expanded by Chapelle and others (in press) to use measured sulfide data to differentiate between iron(III)- and sulfate-reducing conditions. These investigations showed that a systematic approach to characterize redox conditions in ground water could be applied to datasets from diverse hydrogeologic settings using water-quality data routinely collected in regional water-quality investigations. This report describes the Microsoft Excel workbook, RedoxAssignment_McMahon&Chapelle.xls, that assigns the predominant redox process to samples using the framework created by McMahon and Chapelle (2008) and expanded by Chapelle and others (in press). Assignment of redox conditions is based on concentrations of dissolved oxygen (O2), nitrate (NO3-), manganese (Mn2+), iron (Fe2+), sulfate (SO42-), and sulfide (sum of dihydrogen sulfide [aqueous H2S], hydrogen sulfide [HS-], and sulfide [S2-]). The logical arguments for assigning the predominant redox process to each sample are performed by a program written in Microsoft Visual Basic for Applications (VBA). The program is called from buttons on the main worksheet. The number of samples that can be analyzed is only limited by the number of rows in Excel (65,536 for Excel 2003 and XP; and 1,048,576 for Excel 2007), and is therefore appropriate for large datasets.

      2013-04-01

      Modern rock magnetometers and stepwise demagnetization procedures result in the production of large datasets, which need a versatile and fast software for their display and analysis. Various software packages for paleomagnetic analyses have been recently developed to overcome the problems linked to the limited capability and the loss of operability of early codes written in obsolete computer languages and/or platforms, not compatible with modern 64 bit processors. The Demagnetization Analysis in Excel (DAIE) workbook is a new software that has been designed to make the analysis of demagnetization data easy and accessible on an application (Microsoft Excel) widely diffused and available on both the Microsoft Windows and Mac OS X operating systems. The widespread diffusion of Excel should guarantee a long term working life, since compatibility and functionality of current Excel files should be most likely maintained during the development of new processors and operating systems. DAIE is designed for viewing and analyzing stepwise demagnetization data of both discrete and u-channel samples. DAIE consists of a single file and has an open modular structure organized in 10 distinct worksheets. The standard demagnetization diagrams and various parameters of common use are shown on the same worksheet including selectable parameters and user's choices. The remanence characteristic components may be computed by principal component analysis (PCA) on a selected interval of demagnetization steps. Saving of the PCA data can be done both sample by sample, or in automatic by applying the selected choices to all the samples included in the file. The DAIE open structure allows easy personalization, development and improvement. The workbook has the following features which may be valuable for various users: - Operability in nearly all the computers and platforms; - Easy inputs of demagnetization data by "copy and paste" from ASCII files; - Easy export of computed parameters and demagnetization plots; - Complete control of the whole workflow and possibility of implementation of the workbook by any user; - Modular structure in distinct worksheets for each type of analyses and plots, in order to make implementation and personalization easier; - Opportunity to use the workbook for educational purposes, since all the computations and analyses are easily traceable and accessible; - Automatic and fast analysis of a large batch of demagnetization data, such as those measured on u-channel samples. The DAIE workbook and the "User manual" are available for download on a dedicated web site (http://roma2.rm.ingv.it/en/facilities/software/49/daie).

      Nuclear Materials Management Department, a BWXT-corporate partner with Westinghouse Savannah River Company, has established a vision for positioning the organization as a Global Center of Excellence for Strategic Materials Management. NMM's Road to Excellence results from a changing business environment where flexibility and adaptability have become key demands from the Department of Energy customer. Flexibility and adaptability are integral components of the department's MC&A Center of Excellence philosophy in the pursuit of improvement technologies that meet domestic and international safeguards requirements. The customer challenge has put the organization in the forefront of change where benchmarking with other MC&A programs, applying human performance technologies and leveraging INMM leadership and participation opportunities are key ingredients to influencing improvements and changes in existing MC&A standards, policies and practices. The paper challenges MC&A professionals, MC&A program owners and organizational leaders to engage in the debate of new ideas, partnering arrangements and timely deployment of technologies (human performance and technical-based applications) to exponentially improve safeguards programs. Research and development efforts in support of safeguards improvements need to seriously consider deployment to field practitioners within a 2-3 year time frame from inception. INMM plays a crucial role in accelerating such opportunities and establishing improved performance standards above our normal governmental and organizational bureaucracies.

      Previous studies have shown that bredigite (Ca7MgSi4O16) bioceramics possessed excellent biocompatibility, apatite-mineralization ability and mechanical properties. In this paper, the bredigite coating on Ti-6Al-4?V substrate was prepared by plasma spraying technique. The main compositions of the coating were bredigite crystal phase with small parts of amorphous phases. The bonding strength of the coating to Ti-6Al-4?V substrate reached 49.8?MPa, which was significantly higher than that of hydroxyapatite coating and other silicate-based bioceramic coatings prepared by same method. After immersed in simulated body fluid for 2 days, a distinct apatite layer was deposited on the surface of bredigite coating, indicating that the prepared bredigite coating has excellent apatite-mineralization ability. The prepared bredigite coating supported the attachment and proliferation of rabbit bone marrow stem cells. The proliferation level of bone marrow stem cells was significantly higher than that on the hydroxyapatite coating. Our further study showed that the released SiO4 (4-) and Mg(2+) ions from bredigite coating as well as the formed nano-apatite layer on the coating surface might mainly contribute to the improvement of cell proliferation. The results indicated that the bredigite coating may be applied on orthopedic implants due to its excellent bonding strength, apatite mineralization and cytocompatibility. PMID:24131918

      Background Medicare and private plans are encouraging individuals to seek care at hospitals which are designated as centers of excellence. Few evaluations of such programs have been conducted. The Blue Cross Blue Shield Association, whose member plans insure one in three Americans, has established an initiative to designate hospitals as centers of excellence for knee and hip replacement. Objective Comparison of outcomes and costs associated with knee and hip replacement at designated hospitals and other hospitals. Research design Retrospective claims analysis of approximately 54 million enrollees. Study population Individuals with Blue Cross Blue Shield insurance who underwent a primary knee or hip replacement in 2007-2009. Outcomes Primary outcomes were any complication within 30 days of discharge and costs within 90 days following the procedure. Results 80,931 patients had a knee replacement and 39,532 patients had a hip replacement of which 52.2% and 56.5%, respectively, were performed at a designated hospital. Designated hospitals had a larger number of beds and were more likely to be an academic center. Patients with a knee replacement at designated hospitals did not have a statistically significantly lower overall complication rate with an odds ratio of 0.90 (p=0.08). Patients with a hip replacement treated at designated hospitals had a statistically significantly lower risk of complications with an odds ratio of 0.80 (p=0.002). There was no significant difference in 90-day costs for either procedure. Conclusions Hospitals designated as joint replacement centers of excellence had lower rates of complications for hip replacement, but there was no statistically significant difference for knee replacement. It is important to validate the criteria used to designate centers of excellence. PMID:23222470

      Excellent electrical conductivity (EC) generally conflicts with high lap shear strength (LSS) for electrically conductive adhesives (ECAs) since EC increases while LSS decreases with increasing conductive filler content. In this work, the ECAs with the excellent overall performance are developed based on the ternary hybrid of Ag microflakes (Ag-MFs), Ag nanospheres (Ag-NSs), and Ag nanowires (Ag-NWs). First, a low silver content adhesive system is determined. Then, the effects of the relative contents of Ag fillers on the EC and the LSS are studied. It is shown that a small amount of Ag-NSs or Ag-NWs can dramatically improve the EC for the Ag-MF/epoxy adhesives. The Ag-NSs and Ag-NWs with appropriate contents have a synergistic effect in improving the EC. Meanwhile, the LSS of the as-prepared adhesive with the appropriate Ag contents reaches an optimal value. Both the EC and the LSS of the as-prepared ternary hybrid ECA with a low content of 40 wt % Ag are higher than those of the commercial ECAs filled with the Ag-MF content over 60 wt %. Finally, the ternary hybrid ECA with the optimal formulation is shown to be promising for printing the radio frequency identification tag antennas as an immediate application example. PMID:25835391

      Myelodysplastic syndromes (mdss) constitute a heterogeneous group of malignant hematologic disorders characterized by marrow dysplasia, ineffective hematopoiesis, peripheral blood cytopenias, and pronounced risk of progression to acute myeloid leukemia. Azacitidine has emerged as an important treatment option and is recommended by the Canadian Consortium on Evidence-Based Care in mds as a first-line therapy for intermediate-2 and high-risk patients not eligible for allogeneic stem cell transplant; however, practical guidance on how to manage patients through treatment is limited. This best practice guideline provides recommendations by a panel of experts from Canadian centres of excellence on the selection and clinical management of mds patients with azacitidine. Familiarity with the referral process, treatment protocols, dose scheduling, treatment expectations, response monitoring, management of treatment breaks and adverse events, and multidisciplinary strategies for patient support will improve the opportunity for optimizing treatment outcomes with azacitidine.

      This Center-of-Excellence grant has two components: development of an imaging system based on microlaser arrays forms a central project among a group of laser diagnostic and therapeutic efforts primarily funded outside the grant. In these first 8 months we have set up the Microlaser Microscope using small microlaser arrays. We have emphasized the basics of microlaser handling and electronic addressing and the optics of the microscope. Details of electronics and optics given here will be used in the larger arrays which should be available soon. After a description of the central Microlaser Microscope project, we touch briefly on the other projects of the Center, which have been outstandingly fruitful this year. Publications are necessarily concerned with the smaller projects, since the Microlaser Microscope is in its early stages.

      Low storage capacity and poor cycling stability are the main drawbacks of the electrode materials for sodium-ion (Na-ion) batteries, due to the large radius of the Na ion. Here we show that micro-structured molybdenum disulfide (MoS2 ) can exhibit high storage capacity and excellent cycling and rate performances as an anode material for Na-ion batteries by controlling its intercalation depth and optimizing the binder. The former method is to preserve the layered structure of MoS2 , whereas the latter maintains the integrity of the electrode during cycling. A reversible capacity of 90?mAh?g(-1) is obtained on a potential plateau feature when less than 0.5 Na per formula unit is intercalated into micro-MoS2 . The fully discharged electrode with sodium alginate (NaAlg) binder delivers a high reversible capacity of 420?mAh?g(-1) . Both cells show excellent cycling performance. These findings indicate that metal chalcogenides, for example, MoS2 , can be promising Na-storage materials if their operation potential range and the binder can be appropriately optimized.

      We reexamine the mechanism of ferromagnetism in doped TiO2 anatase, using epitaxial Cr?TiO2 with excellent structural quality as a model system. In contrast to highly oriented but defective Cr?TiO2 (˜0.5?B/Cr), these structurally superior single crystal films exhibit negligible ferromagnetism. Similar results were obtained for Co?TiO2. We show for the first time that charge-compensating oxygen vacancies alone, as predicted by F-center mediated exchange, are not sufficient to activate ferromagnetism. Instead, the onset of ferromagnetism correlates with the presence of structural defects.

      Campo, R; Puga, M; Meier Furst, R; Wattiez, A; De Wilde, R L

      2014-01-01

      The complexity of modern surgery has increased the demands and challenges to surgical education and quality control. Today the endoscopic approach is preferred because it increases the surgical possibilities and decreases patient discomfort. Implementing endoscopic surgery without specific training leads to decrease in surgical performance and increase in patient morbidity and mortality. Research of the European Academy for Gynaecological Surgery (+he Academy) has resulted in the establishment of a structured certification and diploma programme with three levels of expertise. One level should be passed to obtain access to the next level. Furthermore one should first pass +he Academy skill exam before entering the clinical surgical competence programme. The European Society for Gynaecological Endoscopy (ESGE) has defined the different diplomas, whereas the Bachelor diploma is seen as a prerequisite to start the in OR one to one clinical training aiming to provide endoscopic skilled individuals to the clinical one to one training. Further diplomas are the Minimal invasive Gynaecological Surgeon (MIGS), master in hysteroscopy and the laparoscopic pelvic surgeon. This programme is based on the best available scientific evidence. It counteracts the problem of the traditional surgical apprentice tutor model and increases patient safety and surgical performance. It is seen as a major step toward standardization of endoscopic surgical training in general. PMID:25593700

      This computer-based assignment forces students to compare and contrast integral and differential forms of the conservation of mass equation, as well as analytical and numerical approaches to solution. Students are given a text description of a simple environmental problem (a conservative tracer diffusing in a one-dimensional system with no-flux boundaries) and are then required to first write equations that describe the system and then implement these equations in an Excel spreadsheet or Matlab m-file. Students then use their spreadsheets/m-files to compare different solution methods and must communicate these results in short text answers.

      The purpose of this study was to develop a nurse-self-made scheduling support system based on the heuristic approach. A Pediatric ICU unit, staffed with 35 nurses, was taken as the case in this study. Nurses' preferred scheduling principles were surveyed. The Excel VBA was used to develop the support system by an informatics nurse. The system was composed of five components: personal scheduling request setting, auto-scheduling, shift modification, report generating and inquiry. The scheduling results were widely accepted by the nurses and the time to plan a monthly schedule was reduced from 4-5 hours to 30 minutes. PMID:17102384

      Rare-earth iron-boron (RE-Fe-B) thin films with a c-axis texture were prepared on a Ta (110) buffer layer on thermally oxidized Si substrates by dc magnetron sputtering. The microstructure, magnetic structure, and magnetic properties of these films were studied as a function of the deposition temperature. The results show that c-axis texture can be obtained over a wide range of deposition temperatures and that the degree of c-axis orientation improves with deposition temperature. It was established that deposition of a RE-Fe-B thin film to obtain grains with a strong c-axis RE2Fe14B texture, coexisting with an amorphous phase, followed by annealing at higher temperature, is an effective route for obtaining excellent hard magnetic properties. Initial results show that a film, which was deposited at 470°C and annealed at 590°C, had a high perpendicular coercivity of 1.8T, in combination with a large maximum energy product of 238kJ/m3.

      The United States (US) nuclear weapons program during the Cold War left a legacy of radioactive, hazardous, chemical wastes and facilities that may seriously harm the environment and people even today. Widespread public concern about the environmental pollution has created an extraordinary demand for the treatment and disposal of wastes in a manner to protect the public health and safety. The pollution abatement and environmental protection require an understanding of technical, regulatory, economic, permitting, institutional, and public policy issues. Scientists and engineers have a major role in this national effort to clean our environment, especially in developing alternative solutions and evaluation criteria and designing the necessary facilities to implement the solutions. The objective of the DOE Chair of Excellence project is to develop a high quality educational and research program in environmental engineering at North Carolina A&T State University (A&T). This project aims to increase the number of graduate and undergraduate students trained in environmental areas while developing a faculty concentrated in environmental education and research. Although A&T had a well developed environmental program prior to the Massie Chair grant, A&T's goal is to become a model of excellence in environmental engineering through the program's support. The program will provide a catalyst to enhance collaboration of faculty and students among various engineering departments to work together in a focus research area. The collaboration will be expanded to other programs at A&T. The past research focus areas include: hazardous and radioactive waste treatment and disposal fate and transport of hazardous chemicals in the environment innovative technologies for hazardous waste site remediation pollution prevention Starting from 2005, the new research focus was in the improvement of accuracy for radioactive contaminant transport models by ensemble based data assimilation. The specific objectives are to: 1). improve model accuracy for use in minimizing health and environmental risk, and 2). improve the decision making process in the selection and application of available technologies for long-term monitoring and safeguard operation at NNSA sites.

      Background Malaria microscopy, while the gold standard for malaria diagnosis, has limitations. Efficacy estimates in drug and vaccine malaria trials are very sensitive to small errors in microscopy endpoints. This fact led to the establishment of a Malaria Diagnostics Centre of Excellence in Kisumu, Kenya. The primary objective was to ensure valid clinical trial and diagnostic test evaluations. Key secondary objectives were technology transfer to host countries, establishment of partnerships, and training of clinical microscopists. Case description A twelve-day "long" and a four-day "short" training course consisting of supervised laboratory practicals, lectures, group discussions, demonstrations, and take home assignments were developed. Well characterized slides were developed and training materials iteratively improved. Objective pre- and post-course evaluations consisted of 30 slides (19 negative, 11 positive) with a density range of 50–660 parasites/?l, a written examination (65 questions), a photographic image examination (30 images of artifacts and species specific characteristics), and a parasite counting examination. Discussion and Evaluation To date, 209 microscopists have participated from 11 countries. Seventy-seven experienced microscopists participated in the "long" courses, including 47 research microscopists. Sensitivity improved by a mean of 14% (CI 9–19%) from 77% baseline (CI 73–81 %), while specificity improved by a mean of 17% (CI 11–23%) from 76% (CI 70–82%) baseline. Twenty-three microscopists who had been selected for a four-day refresher course showed continued improvement with a mean final sensitivity of 95% (CI 91–98%) and specificity of 97% (CI 95–100%). Only 9% of those taking the pre-test in the "long" course achieved a 90% sensitivity and 95% specificity, which increased to 61% of those completing the "short" course. All measures of performance improved substantially across each of the five organization types and in each course offered. Conclusion The data clearly illustrated that false positive and negative malaria smears are a serious problem, even with research microscopists. Training dramatically improved performance. Quality microscopy can be provided by the Centre of Excellence concept. This concept can be extended to other diagnostics of public health importance, and comprehensive disease control strategies.

      Cisplatin (CDDP) is a widely used chemotherapeutic agent. Unfortunately, CDDP is highly ototoxic. We tested D-methionine (D-Met), a sulfur containing compound, as an otoprotectant in male Wistar rats. Complete data sets were obtained for five groups of five animals each, including a treated control group (16 mg/kg CDDP), an untreated control group (administered an equivalent volume of saline) and three groups that received either 75, 150, or 300 mg/kg D-Met 30 min prior to the 16 mg/kg CDDP dosing. Auditory brainstem response (ABR) thresholds were obtained in response to clicks, and 1 kHz, 4 kHz, 8 kHz, and 14 kHz toneburst stimuli, before and 3 days after drug administration. Scanning electron microscopy (SEM) was used to examine the outer hair cells of the apical, middle and basal turns of the cochlea. Animal weight was measured on the first and final day. D-Met provided excellent otoprotection even at the lowest level with complete otoprotection obtained for the 300 mg/kg dosing as measured by both ABR and SEM. D-Met also markedly reduced weight loss and mortality. All animals receiving D-Met (15/15) survived to the end of the study period as opposed to only 5/10 of the treated controls. PMID:8951454

      Midwives provide critical, life-saving care to women and babies. Effective midwives must be clinically competent, with the required knowledge, skills, and attitudes to provide quality care. Their success depends on an environment of supportive supervision, continuing education, enabling policies, and access to equipment and referral facilities. In Freetown, Sierra Leone, the Aberdeen Women's Centre launched a maternity unit with an emphasis on striving for excellence and providing ongoing professional development to its staff midwives. Its success was built upon fostering a sense of responsibility and teamwork, providing necessary resources, conforming to evidence-based standards, and building partnerships. An explicit philosophy of care was crucial for guiding clinical decision making. In its first two years of operation, the Aberdeen Women's Centre assisted 2076 births with two maternal deaths and 92 perinatal deaths. In-service education and supportive supervision facilitated the midwives' professional growth, leading to capable future leaders who are providing exemplary care to delivering mothers and their newborns in Freetown.

      Mentoring is important for the recruitment and retention of qualified nurse faculty, their ongoing career development, and leadership development. However, what are current best practices of mentoring? The purpose of this paper is to provide an overview of a model for excellence in establishing a formal mentoring program for academic nurse educators. Six themes for establishing a formal mentoring program are presented, highlighting best practices in mentoring as culled from experience and the literature. Themes reflect aims to achieve appropriately matched dyads, establish clear mentorship purpose and goals, solidify the dyad relationship, advocate for and guide the protégé, integrate the protégé into the academic culture, and mobilize institutional resources for mentoring support. Attending to the six themes will help mentors achieve important protégé outcomes, such as orientation to the educator role, integration into the academic community, development of teaching, scholarship, and service skills, as well as leadership development. The model is intended to be generalizable for faculty teaching in a variety of academic nursing institution types and sizes. Mentoring that integrates the six themes assists faculty members to better navigate the academic environment and more easily transition to new roles and responsibilities. PMID:22685645

      Drake, Charles L.

      In the symposium on Earth Sciences and Society at the Spring AGU Meeting May 29-June 1, Baltimore, Md.), I was assigned to speak on the maintenance of excellence and national well-being in the Earth sciences. I developed serious writer's block every time I approached the topic until I remembered a paragraph at the beginning of Doug Adams' great text, The Restaurant at the End of the Universe [Adams, 1982]. It tells how [A race of highly intelligent pan-dimensional beings once built themselves a gigantic supercomputer called Deep Thought to calculate once and for all the Answer to the Ultimate Question of Life, Universe and Everything. For seven and a half million years, Deep Thought computed and calculated, and in the end announced that the answer was in fact Forty-two—and so another, even bigger, computer had to be built to find out what the actual question was. And this computer, which was called the Earth, was so large that it was frequently mistaken for a planet-especially by the strange apelike beings who roamed its surface, totally unaware that they were simply part of a gigantic computer program. And this is very odd, because without that fairly simple and obvious piece of knowledge, nothing that ever happened on the Earth could possibly make the slightest bit of sense.

      2014-12-01

      CT examinations represent a substantial portion of the workload for many radiology departments, and optimizing service delivery is a critical function to ensure customer satisfaction. This article describes how the Six Sigma methodology was used in the radiology department at a large academic hospital to improve the patient experience and increase CT capacity while reducing waste and improving staff satisfaction. The 5 distinct phases of Six Sigma are reviewed as they apply to our CT Center of Excellence project: define, measure, analyze, improve, and control. Process metrics used in this project include the percentage of outpatient CT exams started within 5 minutes of the scheduled appointment time, and the number of studies with protocols selected >48 hours before the CT exam is performed. Outcome metrics include monthly department expense per scan and CT Press Ganey "standard test and treatment" mean scores. An approach to developing interventions is described based on identifying critical sources of variation, ranking these by creating risk prioritization numbers, performing root cause analysis, and utilizing the failure mode and effects analysis tool to prioritize possible solutions. Finally, the key features of action plans and a control plan are reviewed. PMID:25467726

      Centipedes are excellent predatory arthropods that inject venom to kill or immobilize their prey. Although centipedes have long been known to be venomous, their venoms remain largely unexplored. The chemical components responsible for centipede predation and the functional mechanisms are unknown. Twenty-six neurotoxin-like peptides belonging to ten groups were identified from the centipede venoms, Scolopendra subspinipes mutilans L. Koch by peptidomics combined with transcriptome analysis, revealing the diversity of neurotoxins. These neurotoxins each contain two to four intramolecular disulfide bridges, and in most cases the disulfide framework is different from that found in neurotoxins from the venoms of spiders, scorpions, marine cone snails, sea anemones, and snakes (5S animals). Several neurotoxins contain potential insecticidal abilities, and they are found to act on voltage-gated sodium, potassium, and calcium channels, respectively. Although these neurotoxins are functionally similar to the disulfide-rich neurotoxins found in the venoms of 5S animals in that they modulate the activity of voltage-gated ion channels, in almost all cases the primary structures of the centipede venom peptides are unique. This represents an interesting case of convergent evolution in which different venomous animals have evolved different molecular strategies for targeting the same ion channels in prey and predators. Moreover, the high level of biochemical diversity revealed in this study suggests that centipede venoms might be attractive subjects for prospecting and screening for peptide candidates with potential pharmaceutical or agrochemical applications.

As this document will review, over that period of time, the COE served its function well. Funds from the Center supported a large number of projects over the last ten years. Many of the people who were supported by the Center Have gone on to distinguished research careers in government, industry and university. In fact, several of the people currently working at NASA Ames were initially funded by the Center mechanism, which served as a useful vehicle for attracting top quality candidates and supporting their research efforts. We are grateful for NASA's support over the years. As we reviewed in the reports for each year, the COE budget generally provided a portion of the true costs of the individual research project. Hence, the funds from the COE were leveraged with funds from industry and other government agencies. In this way, we feel that all parties benefitted greatly from the collaborative spirit and interactive aspects of the COE. The portion of the support from NASA was particularly important in helping members of the COE to set aside the time to publish papers and communicate advances in our understanding of human performance in NASA-related missions.

      Strategic planning for nursing education, when seen through a faculty lens creates a deeper, more meaningful critical analysis of effective program development. New strategies are required for academic institutions to transform their curricula to meet the needs of a dynamic healthcare and changing global environment to provide quality education for students. In this article, an evidence-informed process is presented that was progressively co-created by the faculty and facilitators. Seminal business frameworks, leadership development philosophies, and innovative interventions enabled faculty to become engaged and developed as they created a strategic plan for a future-driven nursing program. Phase One presents the process of developing a strategic plan for excellence in nursing education by leveraging faculty potential and preparing for an upcoming accreditation. In Phase Two, four team members from Phase One continue as part of Phase Two team serving as the collective memory for this initial work. This method of strategic planning encouraged faculty engagement and leadership and laid the groundwork for a positive culture change among nursing faculty. PMID:24516007

      We consider the problem of reducing the edge lengths of a given network so that the modified network has a spanning tree of small total length. It is assumed that each edge e of the given network has an associated function C{sub e} that specifies the cost of shortening the edge by a given amount and that there is a budget B on the total reduction cost. The goal is to develop a reduction strategy satisfying the budget constraint so that the total length of a minimum spanning tree in the modified network is the smallest possible over all reduction strategies that obey the budget constraint. We show that in general the problem of computing optimal reduction strategy for modifying the network as above in NP-hard and present the first polynomial time approximation algorithms for the problem, where the cost functions C{sub e} are allowed to be taken from a broad class of functions. We also present improved approximation algorithms for the class of treewidth-bounded graphs when the cost functions are linear. Our results can be extended to obtain approximation algorithms for more general network design problems such as those considered in [GW, GG+94].

      In this study, a new Ti-Zr-Nb-Sn alloy system was developed as Ni-free biomedical superelastic alloys with a large recovery strain and excellent biocompatibility. Ti-18Zr-(9-16)Nb-(0-4)Sn alloys were prepared by an Ar arc melting method and the effect of composition on the crystal structure and superelastic properties was investigated. A large superelastic recovery strain of 6.0% was observed in Ti-18Zr-12.5Nb-2Sn, Ti-18Zr-11Nb-3Sn, and Ti-18Zr-9.5Nb-4Sn alloys subjected to cold-rolling and solution treatment. XRD results showed that the large recovery strain of Sn-added alloys is due to a combination effect of a large transformation strain and a strong recrystallization texture. The Ti-18Zr-11Nb-3Sn alloy exhibited excellent cyclic stability with an extremely narrow stress hysteresis about 20MPa. Cytocompatibility was also examined using three types of cell lines, murine fibroblast L929, human osteosarcoma SaOS-2, and human umbilical vein endothelial cell HUVEC and the results showed that the Ti-18Zr-11Nb-3Sn alloy exhibited larger cell covering ratios when compared with those of the Ti-50.5Ni alloy for all kinds of cells.

      Background Achieving the Millennium Development Goals (MDGs) and combating hotspots with escalating but preventable communicable diseases remain major challenges in Africa. The European and Developing Countries Clinical Trials Partnership (EDCTP) intervened to combat poverty-related diseases including malaria, tuberculosis and HIV/AIDS, and to conduct multi-centre clinical trials and multi-disciplinary health research through an innovative model of regional Networks of Excellence (NoEs). Methods We participated in a quasi-formative evaluation between October and December 2011 on the 4 regional-led research networks. These included the: Central Africa Network on Tuberculosis, HIV/AIDS and Malaria (CANTAM); East African Consortium for Clinical Research (EACCR); West African Network of Excellence for TB, AIDS and Malaria (WANETAM), and the Trials of Excellence for Southern Africa (TESA) launched between 2009 and 2010. We shared a participatory appraisal of field reports, progress reports and presentations from each network to jointly outline the initial experiences of the merits, outputs and lessons learnt. Results The self-regulating democratic networks, with 64 institutions in 21 African countries, have trained over 1, 000 African scientists, upgraded 36 sites for clinical trials, leveraged additional € 24 million and generated 38 peer-reviewed publications through networking and partnerships. Conclusions The shared initial merits and lessons learnt portray in part the strengthened capacity of these networks for improved research coordination and conduct of planned multi-center clinical trials in Africa. Increased funding by African agencies, governments and international health partners will ensure sustainability of these networks for research capacity development and demonstrate their commitment to achieving the MDGs in Africa.

      The Patient Protection and Affordable Care Act (PPACA, 2010) and the Institute of Medicine's (IOM, 2011) Future of Nursing report have prompted changes in the U.S. health care system. This has also stimulated a new direction of thinking for the profession of nursing. New payment and priority structures, where value is placed ahead of volume in care, will start to define our health system in new and unknown ways for years. One thing we all know for sure: we cannot afford the same inefficient models and systems of care of yesterday any longer. The Data-Driven Model for Excellence in Staffing was created as the organizing framework to lead the development of best practices for nurse staffing across the continuum through research and innovation. Regardless of the setting, nurses must integrate multiple concepts with the value of professional nursing to create new care and staffing models. Traditional models demonstrate that nurses are a commodity. If the profession is to make any significant changes in nurse staffing, it is through the articulation of the value of our professional practice within the overall health care environment. This position paper is organized around the concepts from the Data-Driven Model for Excellence in Staffing. The main concepts are: Core Concept 1: Users and Patients of Health Care, Core Concept 2: Providers of Health Care, Core Concept 3: Environment of Care, Core Concept 4: Delivery of Care, Core Concept 5: Quality, Safety, and Outcomes of Care. This position paper provides a comprehensive view of those concepts and components, why those concepts and components are important in this new era of nurse staffing, and a 3-year challenge that will push the nursing profession forward in all settings across the care continuum. There are decades of research supporting various changes to nurse staffing. Yet little has been done to move that research into practice and operations. While the primary goal of this position paper is to generate research and innovative thinking about nurse staffing across all health care settings, a second goal is to stimulate additional publications. This includes a goal of at least 20 articles in Nursing Economic$ on best practices in staffing and care models from across the continuum over the next 3 years. PMID:25144948

      This paper reports the preparation and characterization of carbonaceous materials obtained from three types of vegetable wastes provided by agricultural industries. Soft carbonization (280°C) and H3PO4-activation procedures were used to convert the agricultural wastes to carbon powders with high adsorbent capacities. This process is excellent for eliminating and exploiting the huge masses (many tons) of vegetable residues remaining after each harvest every year in several Colombian agro-industries. The powders were characterized by X-ray diffraction (XRD), IR spectroscopy, scanning electron microscopy (SEM), and N2-adsorption isotherms. XRD and IR verified the formation of carbons, and SEM showed small particles (20-500?µm) with characteristic morphology for each type of residue used and abundant cavities of different sizes. The N2-adsorption analyses showed that the carbons had high adsorption capacities with important surface area values and large pore volumes. The use of the activated carbonaceous materials as adsorbent of azo dyes (allura red and sunset yellow) from aqueous solutions was evaluated. The results showed a good adsorption capacity indicating the potentiality of these materials as pollutant adsorbents in food industry wastewaters. These results indicate that these powders can be used as potential adsorbents for different gaseous or liquid pollutants. PMID:25189634

      In this paper an attempt is made to focus on the ideological and practical implications of the new cultural forms of healthcare sector management variously described as institutional excellence, empowerment, total quality and human resource management. Thus, I look in detail at the managerial and academic claims concerning the mobilisation of corporate culture and go on to emphasise the impact which the literature of culture management has had on nursing employees and healthcare organisations. I also highlight the restrictions of the applied research approaches and argue that the managerial and poststructural literature is limited in that its conceptualisation of culture and change is incomplete. The focus switches then to a range of literature which has been used to study change with a labour process perspective and explains why an approach based upon the study of the disparity between the cultural rhetoric and the day-to-day practice, as well as how people experience and respond to that disparity, is to be preferred. Furthermore, I gain substance from a variety of viewpoints in order to discover a suitable way of putting the matter of interest into context. Drawing on the analytical framework of the sector model, which differentiates in the economy between private and state production sectors, it is possible to distinguish between the different modes of rationality governing each sector. As a basis for further contextualisation, the powerful and privileged positions of nursing as well as other healthcare professionals and the distinctive character of their employment relationships are considered. The paper concludes that an extended labour process analysis is necessary to challenge the way in which the concept of culture is applied by nursing academics and practitioners. PMID:12460421

      Thermal properties of several vegetable oils such as soy, corn, and avocado commercial oils were obtained by using a photopyroelectric technique. The inverse photopyroelectric configuration was used in order to obtain the thermal effusivity of the oil samples. The theoretical equation for the photopyroelectric signal in this configuration, as a function of the incident light modulation frequency, was fitted to the experimental data in order to obtain the thermal effusivity of these samples. The obtained results are in good agreement with the thermal effusivity reported for other vegetable oils. All measurements were done at room temperature.

      Astronauts currently acquire ultrasound images on the International Space Station with the assistance of real-time remote guidance from an ultrasound expert in Mission Control. Remote guidance will not be feasible when significant communication delays exist during exploration missions beyond low-Earth orbit. For example, there may be as much as a 20- minute delay in communications between the Earth and Mars. Virtual-guidance, a pre-recorded audio-visual tutorial viewed in real-time, is a viable modality for minimally trained scanners to obtain diagnostically-adequate images of clinically relevant anatomical structures in an autonomous manner. METHODS: Inexperienced ultrasound operators were recruited to perform carotid artery (n = 10) and ophthalmic (n = 9) ultrasound examinations using virtual guidance as their only instructional tool. In the carotid group, each each untrained operator acquired two-dimensional, pulsed, and color Doppler of the carotid artery. In the ophthalmic group, operators acquired representative images of the anterior chamber of the eye, retina, optic nerve, and nerve sheath. Ultrasound image quality was evaluated by independent imaging experts. RESULTS: Eight of the 10 carotid studies were judged to be diagnostically adequate. With one exception the quality of all the ophthalmic images were adequate to excellent. CONCLUSION: Diagnostically-adequate carotid and ophthalmic ultrasound examinations can be obtained by untrained operators with instruction only from an audio/video tutorial viewed in real time while scanning. This form of quick-response-guidance, can be developed for other ultrasound examinations, represents an opportunity to acquire important medical and scientific information for NASA flight surgeons and researchers when trained medical personnel are not present. Further, virtual guidance will allow untrained personnel to autonomously obtain important medical information in remote locations on Earth where communication is difficult or absent.

      When carefully constructed, performance management systems can help health care organizations direct their efforts toward strategic goals, high performance, and continuous improvement needed to ensure high-quality patient care and cost control. The effective management of performance is an integral component in hospital and health care systems that are recognized for excellence by the Malcolm Baldrige National Quality Award in Health Care. Using the framework in the 2011-2012 Health Care Criteria for Performance Excellence, this article identifies the best practices in performance management demonstrated by 15 Baldrige recipients. The results show that all of the recipients base their performance management systems on strategic goals, outcomes, or competencies that cascade from the organizational to the individual level. At the individual level, each hospital or health system reinforces the strategic direction with performance evaluations of leaders and employees, including the governing board, based on key outcomes and competencies. Leader evaluations consistently include feedback from internal and external stakeholders, creating a culture of information sharing and performance improvement. The hospitals or health care systems also align their reward systems to promote high performance by emphasizing merit and recognition for contributions. Best practices can provide a guide for leaders in other health systems in developing high-performance work systems. PMID:24168871

      Presented in this paper is a hybrid polymer/titanium dioxide (TiO2) vesicle that has excellent UV-screening efficacy and strong capacity to encapsulate antioxidant agents. Poly(ethylene oxide)-block-poly(2-(dimethylamino)ethyl methacrylate)-block-polystyrene (PEO-b-PDMAEMA-b-PS) triblock terpolymer was synthesized by atom transfer radical polymerization (ATRP) and then self-assembled into vesicles. Those vesicles showed excellent UV-screening property due to the scattering by vesicles and the absorption by PS vesicle membrane. The selective deposition of solvophobic tetrabutyl titanate in the PDMAEMA shell and the PS membrane of the vesicles led to the formation of polymer/TiO2 hybrid vesicles, resulting in an enhanced UV-screening property by further reflecting and scattering UV radiation. The vesicles can effectively encapsulate antioxidant agents such as ferulic acid (up to 57%), showing a rapid antioxidant capability (within 1 min) and a long-lasting antioxidant effect.

      This study presents PKSolver, a freely available menu-driven add-in program for Microsoft Excel written in Visual Basic for Applications (VBA), for solving basic problems in pharmacokinetic (PK) and pharmacodynamic (PD) data analysis. The program provides a range of modules for PK and PD analysis including noncompartmental analysis (NCA), compartmental analysis (CA), and pharmacodynamic modeling. Two special built-in modules, multiple absorption sites (MAS) and enterohepatic circulation (EHC), were developed for fitting the double-peak concentration-time profile based on the classical one-compartment model. In addition, twenty frequently used pharmacokinetic functions were encoded as a macro and can be directly accessed in an Excel spreadsheet. To evaluate the program, a detailed comparison of modeling PK data using PKSolver and professional PK/PD software package WinNonlin and Scientist was performed. The results showed that the parameters estimated with PKSolver were satisfactory. In conclusion, the PKSolver simplified the PK and PD data analysis process and its output could be generated in Microsoft Word in the form of an integrated report. The program provides pharmacokinetic researchers with a fast and easy-to-use tool for routine and basic PK and PD data analysis with a more user-friendly interface. PMID:20176408

      A water strider's floating mechanism is of significance for the design of new biomimetic robots. However, the explanation of this mechanism has not been fully comprehended due to a lack of effective experimental methods. We describe a novel transmission speckle correlation technique, which is used to determine the deformation of liquid surfaces caused by a resting water strider, as well as a calculation of the resulting forces in the vertical direction. Furthermore, the variation of the liquid surface morphology at different times in the process of a water strider being unconscious has been measured and analyzed. The results show that the wax material secreted by water striders is a vital source for the excellent floating ability of a water strider, and that the effective time of the wax is less than 2h.

      Regarding the hypothesis that neonicotinoid insecticides used for seed coating of agricultural crops - mainly corn, sunflower and seed rape - are related to the extensive death of honey bees, the phenomenon of corn seedling guttation has been recently considered as a possible route of exposure of bees to these systemic insecticides. In the present study, guttation drops of corn plants obtained from commercial seeds coated with thiamethoxam, clothianidin, imidacloprid and fipronil have been analyzed by an optimized fast UHPLC-DAD procedure showing excellent detection limits and accuracy, both adequate for the purpose. The young plants grown both in pots - in greenhouse - and in open field from coated seeds, produced guttation solutions containing high levels of the neonicotinoid insecticides (up to 346 mg L(-1) for imidacloprid, 102 mg L(-1) for clothianidin and 146 mg L(-1) for thiamethoxam). These concentration levels may represent lethal doses for bees that use guttation drops as a source of water. The neonicotinoid concentrations in guttation drops progressively decrease during the first 10-15 days after the emergence of the plant from the soil. Otherwise fipronil, which is a non-systemic phenylpyrazole insecticide, was never detected into guttation drops. Current results confirm that the physiological fluids of the corn plant can effectively transfer neonicotinoid insecticides from the seed onto the surface of the leaves, where guttation drops may expose bees and other insects to elevated doses of neurotoxic insecticides.

      The rotation invariance of the classical disc-based moments, such as Zernike moments (ZMs), pseudo-ZMs (PZMs), and orthogonal Fourier-Mellin moments (OFMMs), makes them attractive as descriptors for the purpose of recognition tasks. However, less work has been performed for the generalization of these moment functions. In this paper, four general forms are developed to obtain a class of disc-based generalized radial polynomials that are orthogonal over the unit circle. These radial polynomials are scaled to ensure numerical stability, and some useful properties are discussed for potential applications they could be used in. Then, these scaled radial polynomials are used as kernel functions to construct a series of unit discbased generalized orthogonal moments (DGMs). The variation of parameters in DGMs can form various types of orthogonal moments: 1) generalized ZMs; 2) generalized PZMs; and 3) generalized OFMMs. The classical ZMs, PZMs, and OFMMs correspond to a special case of these three generalized moments for which the free parameter ? = 0. Each member of this family will share some excellent properties for image representation and recognition tasks, such as orthogonality and rotation invariance. In addition, we have also developed two algorithms, the so-called m-recursive and n-recursive methods for the computation of these proposed radial polynomials to improve the numerical stability. Experimental results show that the proposed methods are superior to the classical disc-based moments in terms of image representation capability and classification accuracy. PMID:25361505

      This article describes the fabrication of nanocellulose fibers (NCFs) with different morphologies and surface properties from biomass resources as well as their self-aggregation into lightweight aerogels. By carefully modulating the nanofibrillation process, four types of NCFs could be readily fabricated, including long aggregated nanofiber bundles, long individualized nanofibers with surface C6 -carboxylate groups, short aggregated nanofibers, and short individualized nanofibers with surface sulfate groups. Free-standing lightweight aerogels were obtained from the corresponding aqueous NCF suspensions through freeze-drying. The structure of the aerogels could be controlled by manipulating the type of NCFs and the concentration of their suspensions. A possible mechanism for the self-aggregation of NCFs into two- or three-dimensional aerogel nanostructures was further proposed. Owing to web-like structure, high porosity, and high surface reactivity, the NCF aerogels exhibited high mechanical flexibility and ductility, and excellent properties for water uptake, removal of dye pollutants, and the use as thermal insulation materials. The aerogels also displayed sound-adsorption capability at high frequencies. PMID:24420495

      Polyvinylidene fluoride (PVDF) ultrafiltration membranes were investigated for the first time in vanadium redox flow battery (VFB) applications. Surprisingly, PVDF ultrafiltration membranes with hydrophobic pore walls and relatively large pore sizes of several tens of nanometers proved able to separate vanadium ions and protons efficiently, thus being suitable as a VFB separator. The ion selectivity of this new type of VFB membrane could be tuned readily by controlling the membrane morphology via changes in the composition of the membrane casting solution, and the casting thickness. The results showed that the PVDF membranes offered good performances and excellent stability in VFB applications, where it could, performance-wise, truly substitute Nafion in VFB applications, but at a much lower cost.

      Precipitation hardening in the Zr-based alloy Excel (Zr-3.5 wt.% Sn-0.8 wt.% Mo-0.8 wt.% Nb) was studied using hardness testing and transmission electron microscopy (TEM). Solution treatment at 890 °C, in the ?Zr + ?Zr region, and 980 °C, in the ?Zr region, followed by water-quenching and aging resulted in an increase of hardness, of up to 47% compared to the annealed material. The optimum condition for aging heat treatment was found to be 450 °C for 1-2 h. The precipitates were observed only in the transformed ?Zr martensitic phase. Energy dispersive X-ray spectroscopy (EDS) in TEM showed the precipitate composition to be Zr-30 wt.% Mo-25 wt.% Nb-2 wt.% Fe. The crystal structure of the precipitates was determined to be hexagonal with a = 0.294 nm and c = 0.448 nm, i.e. c/a = 1.526.

    11. Witnessing excellence in action: the 'other-praising' emotions of elevation, gratitude, and admiration.

      People are often profoundly moved by the virtue or skill of others, yet psychology has little to say about the 'other-praising' family of emotions. Here we demonstrate that emotions such as elevation, gratitude, and admiration differ from more commonly studied forms of positive affect (joy and amusement) in many ways, and from each other in a few ways. The results of studies using recall, video induction, event-contingent diary, and letter-writing methods to induce other-praising emotions suggest that: elevation (a response to moral excellence) motivates prosocial and affiliative behavior, gratitude motivates improved relationships with benefactors, and admiration motivates self-improvement. Mediation analyses highlight the role of conscious emotion between appraisals and motivations. Discussion focuses on implications for emotion research, interpersonal relationships, and morality.

      Purpose: This work contains an alternative methodology for obtaining correction factors for ionization chamber (IC) dosimetry of small fields and composite fields such as IMRT. The method is based on the convolution/superposition (C/S) of an IC response function (RF) with the dose distribution in a certain plane which includes chamber position. This method is an alternative to the full Monte Carlo (MC) approach that has been used previously by many authors for the same objective. Methods: The readout of an IC at a point inside a phantom irradiated by a certain beam can be obtained as the convolution of the dose spatial distribution caused by the beam and the IC two-dimensional RF. The proposed methodology has been applied successfully to predict the response of a PTW 30013 IC when measuring different nonreference fields, namely: output factors of 6 MV small fields, beam profiles of cobalt 60 narrow fields and 6 MV radiosurgery segments. The two-dimensional RF of a PTW 30013 IC was obtained by MC simulation of the absorbed dose to cavity air when the IC was scanned by a 0.6 x 0.6 mm{sup 2} cross section parallel pencil beam at low depth in a water phantom. For each of the cases studied, the results of the IC direct measurement were compared with the corresponding obtained by the C/S method. Results: For all of the cases studied, the agreement between the IC direct measurement and the IC calculated response was excellent (better than 1.5%). Conclusions: This method could be implemented in TPS in order to calculate dosimetry correction factors when an experimental IMRT treatment verification with in-phantom ionization chamber is performed. The miss-response of the IC due to the nonreference conditions could be quickly corrected by this method rather than employing MC derived correction factors. This method can be considered as an alternative to the plan-class associated correction factors proposed recently as part of an IAEA work group on nonstandard field dosimetry.

      The External Quality Control Program of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) include controls for bacteriology, serology, mycology, parasitology, mycobacteria, virology and molecular microbiology. This article presents the most relevant conclusions and lessons from the 2012 controls. As a whole, the results obtained in 2012 confirm the excellent skill and good technical standards found in previous editions. However, erroneous results can be obtained in any laboratory and in clinically relevant determinations. Once again, the results of this program highlighted the need to implement both internal and external controls in order to assure the maximal quality of the microbiological tests. PMID:24630577

      1997-01-01

      This Wu Chang-Hua lecture is concerned with the development of analysis and computational capability for turbomachinery flows which is based on detailed flow field physics. A brief review of the work of Professor Wu is presented as well as a summary of the current NASA aeropropulsion programs. Two major areas of research are described in order to determine our predictive capabilities using modern day computational tools evolved from the work of Professor Wu. In one of these areas, namely transonic rotor flow, it is demonstrated that a high level of accuracy is obtainable provided sufficient geometric detail is simulated. In the second case, namely turbine heat transfer, our capability is lacking for rotating blade rows and experimental correlations will provide needed information in the near term. It is believed that continuing progress will allow us to realize the full computational potential and its impact on design time and cost.
