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.

Portable narcotics detector and the results obtained in field tests  

NASA Astrophysics Data System (ADS)

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.

a New Basic One-Dimensional One-Layer Model Obtains Excellent Agreement with the Observed Earth Temperature

The Earth radiation and energy budget is calculated by a manifold of rather complex Global Circulation Models. Their outcome mostly cannot identify integral radiation or energy budget relations. Therefore it is reasonable to look at more basic models to identify the main aspects of the model results. The simplest one of all of those is a one-dimensional one-layer model. However,

Obtaining meaningful results from Fourier deconvolution of reaction time data.  

PubMed

The technique of Fourier deconvolution is a powerful tool for testing distributional predictions of stage models of reaction time. However, direct application of Fourier theory to reaction time data has sometimes produced disappointing results. This article reviews Fourier transform theory as it applies to the problem of deconvolving a component of the reaction time distribution. Problems encountered in deconvolution are shown to be due to the presence of noise in the Fourier transforms of the sampled distributions, which is amplified by the operation of deconvolution. A variety of filtering techniques for the removal of noise are discussed, including window functions, adaptive kernel smoothing, and optimal Wiener filtering. The best results were obtained using a window function whose pass band was determined empirically from the power spectrum of the deconvolved distribution. These findings are discussed in relation to other, nontrigonometric approaches to the problem of deconvolution. PMID:2270239

Results obtained using a 61-pixel Hybrid Photodiode scintillation camera  

NASA Astrophysics Data System (ADS)

In this paper, the performance characteristics of a small prototype gamma-camera system based on the use of the recently developed Multi-pixel Hybrid Photodiode (M-HPD) are described. A compact read-out system has been developed to record the signals from all 61 pixels in the device. Single photo-electrons can be detected in each pixel. This provides an excellent means for calibrating the signal detected in each pixel in terms of the number of photo-electrons. The position-resolution of the detector has been measured as a function of the number of photo-electrons by using a finely collimated beam of light. The spatial resolution (FWHM) was measured to be 0.5 mm for a signal level of 100 photo-electrons. The M-HPD has also been used in a miniature Anger-camera system to locate the position of interaction of gamma-ray photons in a scintillator. The light-pool generated by each event in a continuous scintillation crystal is spread in the 2mm thick entrance window of the M-HPD so that the photo-electron cloud is detected by a small cluster of anode pixels. The light-spread information has been measured and is compared with optical Monte Carlo simulations.

Short Hairpin RNA Suppression of Thymidylate Synthase Produces DNA Mismatches and Results in Excellent Radiosensitization  

SciTech Connect

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.

Suction lipectomy: an excellent adjutant to improve the results of breast reconstruction with RAM flaps.  

PubMed

It has been said about breast reconstruction with implants that a patient should not expect more than a mound that will fill out her brassiere or bathing suit. Autogenous tissue breast reconstruction has changed this. One of the great advantages of autogenous reconstruction over implants is that the breast remains soft, supple, and warm, improving with time as the scars begin to fade and becoming more natural and pendulous. Furthermore, since the new breast is made of fat, we can change its size, enhance its shape, and sculpture it with a suction lipectomy cannula to make it look practically identical to the opposite. We look upon breast reconstruction with rectus abdominis myocutaneous (RAM) flaps as a torsoplasty because of the improvements to the two areas involved: the reconstructed breast and the resulting abdominal lipectomy. This torsoplasty is done in two stages: One is the actual transfer of the rectus abdominis flap in which the skin and fat involved is designed to try to give an aesthetic dermolipectomy but without compromising the vascularity of the flap. Three or four months later, we perform the second-stage torsoplasty where the suction-assisted lipectomy plays a fundamental role and which is the subject of this article. PMID:2146860

NASA Astrophysics Data System (ADS)

We propose a novel approach using Co underlayer to grow FeCo thin films by sputtering oblique deposition technique to achieve desirable performance for high frequency applications working in an environment where in the temperature may fluctuate. In particular, the films show a very high resonance frequency tunable up to 6.2 GHz with the permeability of 391 and an excellent thermal stability with the variation less than 1% in the temperature range from 300 K to 420 K.

Paternity analysis in Excel.  

PubMed

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

Excellent results with the cemented Lubinus SP II 130-mm femoral stem at 10 years of follow-up  

PubMed Central

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.

Transferability of results obtained for sodium, potassium and chloride ions with different analysers.  

PubMed

In this study we have assessed transferability in seven different analysers commonly used in clinical chemistry laboratories to measure sodium, potassium and chloride ions. The inaccuracy and linearity of the techniques were satisfactory in most cases, and therefore all the equipment may be used in both pathological and normal ranges of the electrolytes evaluated. In most cases it was possible to correct the inaccuracy. The equipment which gave the best performance when analysing the three ions assessed after considering the Process Capability Index (CPI) and Performance Index (PI) was Nova-5. According to Hyltoft-Petersen's criteria, the results obtained for the three ions with the different analysers cannot be used indiscriminately, apart from potassium. However, after comparison of the results obtained by indirect potentiometry with those obtained by other techniques, we can conclude that the transferability of results is possible in almost every case, as standard deviation from regression (Sy,x) was lower than the permissible analytical error.

Are the results obtained in randomized clinical trials on antiemetics sufficiently reproducible in clinical practice?  

PubMed

To evaluate whether the incidence of emesis in patients undergoing cisplatin chemotherapy and receiving the standard antiemetic prophylaxis during daily clinical practice was similar to that obtained in antiemetic trials, a prospective study was carried out, adopting very wide eligibility criteria. In the first cycle of chemotherapy, 308 consecutive adult patients were evaluated, 112 in the second, and 89 in the third cycle. Results were compared with those obtained in three published randomized clinical trials. In the first cycle of chemotherapy, complete protection from acute vomiting/nausea was obtained by 78.9% (243/308) and 71.8% (221/308) of patients. These results were quite similar to those obtained in the three randomized studies: 79.7%/72.1%, 78.3%/71.4%, and 78.7%/77.2%. No significantly different results among these studies were obtained, even in the second and third cycles of chemotherapy. In conclusion, in patients undergoing cisplatin chemotherapy, the effectiveness of the same standard antiemetic prophylaxis is similar to the efficacy found in randomized clinical trials, regardless of the eligibility/exclusion criteria and the setting of the study.

Excellent results with cementless total hip arthroplasty and alumina-on-alumina pairing: minimum ten-year follow-up.  

PubMed

Ceramic-on-ceramic coupling is thought to be a durable alternative to metal- or alumina-on-polyethylene pairing. No evidence exists suggesting superior clinical and radiological results for hydroxyapatite-coated stems versus uncoated stems. The aim of this study is to report the performance of an alumina-on-alumina bearing cementless total hip arthroplasty and to compare stems with a tapered design with and without hydroxyapatite coating. We prospectively analysed the results of cementless tapered femoral stems (40 hydroxyapatite-coated versus 22 uncoated stems), a metal-backed fibre mesh hydroxyapatite-coated socket and alumina-on-alumina pairing. Of 75 hips studied, 62 were available for follow-up (mean of 10.5 years after surgery). The average Harris hip score was 90. Only one hydroxyapatite-coated stem was revised for aseptic loosening. One instance of non-progressive osteolysis was detected around a screw of a cup. All other components showed radiographic signs of stable ingrowth. Hydroxyapatite coating of the stem had no significant impact on the clinical or radiological results. Total hip arthroplasty with the presented implant and pairing provides a durable standard for all patients requiring hip joint replacement against which all newer generations of cementless implants should be judged.

Excellent results of immunocomplex capture fluorescence analysis-I for cross-match test in renal transplantation.  

PubMed

A flow cytometry cross-match (FCXM) test is the gold standard for detection of human leukocyte antigen (HLA) antibodies in renal transplantation because of its high sensitivity. However, this technique can produce false-positive results when non-HLA antibodies or low-titer donor-specific antibodies (DSA) are detected. To determine the clinical relevance of the recently introduced novel cross-match test termed immunocomplex capture fluorescence analysis (ICFA), we retrospectively compared the results of ICFA and FCXM, including a single-antigen bead test for detection of DSA in renal transplant recipients. We found a correlation of 71.4% (235/329) between the results of ICFA-I and FCXM-T, whereas that between ICFA-II and FCXM-B was 41.1% (134/326). Ninety-four patients were ICFA-I negative and FCXM-T positive, and 188 were ICFA-II negative and FCXM-B positive, whereas 46.8% (44/94) and 61.7% (116/188) were found to be DSA-I and DSA-II negative, respectively, which classified them into the non-HLA antibody and low-titer DSA groups, respectively. The mean value of molecules of equivalent soluble fluorochrome for DSA-I was 22,994 in the ICFA-I-positive group, which was significantly higher than 2117 in the negative group (P < .0001), whereas there was no significant difference for DSA-II between the ICFA-II-positive and ICFA-II-negative groups. Graft survival in the ICFA-I-negative group was significantly higher than that in the ICFA-I-positive group (P = .0058). Our results indicate that ICFA-I does not respond to non-HLA antibodies or low-titer DSA, which have influence on graft survival. Therefore, this novel hybrid test, which combines cross-match testing and HLA antibody detection functions, may be useful for clinical pretransplantation evaluation of renal transplantation patients.

Curettage-cryosurgery for non-melanoma skin cancer of the external ear: excellent 5-year results.  

PubMed

In this 5-year follow-up study, 60 auricular non-melanoma skin cancers, selected at a skin tumour clinic, were treated by a thorough curettage with different sized curettes followed by cryosurgery in a double freeze-thaw cycle. Tumours of the external auditory canal were excluded. Forty-seven basal cell carcinomas (BCCs), nine squamous cell carcinomas (SCCs), three Bowen's disease and one basisquamous cancer were included. The mean diameter of the malignancies was 18 mm (range 5-70). Morphoeiform BCCs, recurrent BCCs with fibrotic component and most of the SCCs were selected for Mohs' micrographic surgery. Forty-two patients with 47 tumours were followed-up for at least 5 years with only one recurrence. Thirteen patients, followed-up for 2-4 years, died from other causes with no sign of recurrence at their last visit. No major problems after treatment were registered and the cosmetic result was good or acceptable in all patients. PMID:10233225

Phase III studies on novel oral anticoagulants for stroke prevention in atrial fibrillation: a look beyond the excellent results.  

PubMed

In this overview we address the three phase III studies that compared new oral anticoagulants (dabigatran, rivaroxaban and apixaban) with warfarin in the setting of stroke prevention in atrial fibrillation. Strengths and weaknesses of the studies were examined in detail through indirect comparison. We analyze and comment the inclusion and exclusion criteria, the characteristics of randomized patients, the primary efficacy and safety end points and side effects. All new oral anticoagulants resulted in being non-inferior to vitamin K antagonists in reducing stroke or systemic embolism in patients with atrial fibrillation. Dabigatran 150 mg and apixaban were superior to vitamin K antagonists. Importantly, new oral anticoagulants significantly reduced hemorrhagic stroke in all three studies. Major differences among new oral anticoagulants include the way they are eliminated and side effects. Both dabigatran and apixaban were tested in low- to moderate-risk patients (mean CHADS2 [Congestive heart failure, Hypertension, Age, Diabetes, Stroke] score = 2.1-2.2) whereas rivaroxaban was tested in high-risk patients (mean CHADS2 score = 3.48) and at variance with dabigatran and apixaban was administered once daily. Apixaban significantly reduced mortality from any cause. The choice of a new oral anticoagulant should take into account these and other differences between the new drugs. PMID:22827490

Digital Processing and Segmentation of Breast Microcalcifications Images Obtained by a Si Microstrips Detector: Preliminary Results  

NASA Astrophysics Data System (ADS)

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.

Prenatal cytogenetic diagnosis in Spain: analysis and evaluation of the results obtained from amniotic fluid samples during the last decade.  

PubMed

Chromosome abnormalities are one of the main causes of congenital defects, and establishing their frequency according to the different clinical indications for invasive procedure during pregnancy is especially important for genetic counselling. We analyzed the results of 29,883 amniotic fluid samples referred to our laboratory for cytogenetic studies from 1998 to 2009, which constitutes the largest series of cytogenetic analysis performed on amniotic fluid samples in Spain. The number of samples received tended to increase from 1998 to 2005, but after 2005 it decreased substantially. Cytogenetic results were obtained in 99.5% of the samples, and the detected incidence of chromosome abnormalities was 2.9%. Of these, 48.1% consisted of classical autosomal aneuploidies, trisomy 21 being the most frequent one. The main clinical indications for amniocentesis were positive prenatal screening and advanced maternal age, but referral reasons with highest positive predictive values were, excluding parental chromosome rearrangement, increased nuchal translucency (9.2%) and ultrasound abnormalities (6.6%). In conclusion, performing the karyotype on amniotic fluid samples is a good method for the detection of chromosome abnormalities during pregnancy. The number of cytogenetic studies on amniotic fluid has now decreased, however, due to the implementation of first trimester prenatal screening for the detection of Down syndrome, which allows karyotyping on chorionic villus samples. Our results also show that both ultrasound abnormalities and increased nuchal translucency are excellent clinical indicators for fetal chromosome abnormality. PMID:21492994

Results of the 2005 UT Modelling Benchmark Obtained with the CIVA Software Developed at the CEA  

NASA Astrophysics Data System (ADS)

The CIVA software developed at the French Atomic Energy Commission for processing and simulating NDT data includes tools for modelling the whole ultrasonic inspection of a component in which virtual defects are positioned. In this paper, Kirchhoff's approximation and reciprocity principle were applied to predict the reception by the transducer of waves scattered by the defect. Results given and discussed are those obtained for the various problems of the 2005 UT benchmark modelling session. These results concern the echographic responses of side drilled holes and cracks using immersed inspection techniques.

Deep-Sequencing Protocols Influence the Results Obtained in Small-RNA Sequencing  

PubMed Central

Second-generation sequencing is a powerful method for identifying and quantifying small-RNA components of cells. However, little attention has been paid to the effects of the choice of sequencing platform and library preparation protocol on the results obtained. We present a thorough comparison of small-RNA sequencing libraries generated from the same embryonic stem cell lines, using different sequencing platforms, which represent the three major second-generation sequencing technologies, and protocols. We have analysed and compared the expression of microRNAs, as well as populations of small RNAs derived from repetitive elements. Despite the fact that different libraries display a good correlation between sequencing platforms, qualitative and quantitative variations in the results were found, depending on the protocol used. Thus, when comparing libraries from different biological samples, it is strongly recommended to use the same sequencing platform and protocol in order to ensure the biological relevance of the comparisons.

Results and validation of marine surface wind speed obtained from SAC-D/Aquarius MWR  

NASA Astrophysics Data System (ADS)

MWR (MicroWave Radiometer) is a radiometer on board SAC-D/Aquarius satellite, launched in June 2011. The SAC-D/Aquarius science mission was developed jointly by the Nacional Space Agency of Argentina (CONAE, Comisión Nacional de Actividades Espaciales) and the National Aeronautics and Space Administration of USA (NASA), that focuses on understanding the interaction between the global water cycle, ocean circulation and climate by measuring sea surface salinity. MWR is a three channel push broom, Dicke radiometer, that has 16 beams, 8 forward-looking at 36.5 GHz (in vertical and horizontal polarization) and 8 aft-looking at 23.8 GHz (in horizontal polarization), with a swath of approximately 380 Km. The beams are arranged to have two incidence angles, one of 52° (odd beams) and one of 58° (even beams) for both forward and aft-looks. Since recently, CONAE with collaboration of CFRSL (Central Florida Remote Sensing Laboratory), are generating geophysical parameters, all over the sea surface, using brightness temperature measurements from MWR. These parameters include columnar water vapor, wind speed, sea ice concentration and rain rate, which are ancillary data for the Aquarius salinity measurements. We present in this paper the first results of wind speed over the sea, obtained using the MWR data. The wind speed retrieval algorithm is based on the microwave radiative transfer theory by Wentz [1]. The algorithm developed uses MWR brigthness temperature at 36.5 GHz in both polarizations and sea surface temperature obtained from GDAS. As a result, the neutral stability ocean surface wind speed at 10 m height and the atmospheric trasnmissivity at 36.5 GHz are retrieved. In addition, a validation process in collaboration with the Naval Hydrographic Service of Argentina (SHN) has started. The final goal of this on-going work is to assess the quality of MWR wind data in conjunction with surface wind observations from other sources in a data assimilation system. At this first stage, MWR and WindSat collocated wind speed observations are analyzed. Here we show the preliminary validation statistics and considerations on possible sources of discrepancies and the room for improvements.

Monitoring system for a synthesizer at SPring-8 synchrotron radiation facility and obtained results  

NASA Astrophysics Data System (ADS)

Beam orbit distortion in all dispersive sections was observed in the SPring-8 storage ring during beam commissioning. In order to confirm the stability of the radio frequency (RF) synthesizer, a monitoring system was developed. The system consists of a frequency counter referenced to a global positioning system (GPS) receiver. With this system, the output of the synthesizer, which uses an external 10 MHz-Rubidium atomic clock with the time accuracy of ?t/t=10-12, is correctly monitored with 11 digits absolute accuracy, verifying that the synthesizer works well. Measurement of the circumference of the SPring-8 storage ring reveals the effect of tidal forces and seasonal temperature variations on beam orbit. To maintain the center axis of photon radiation in experimental beam lines, a beam energy correction is carried out. The frequency of the RF synthesizer is changed every 5 min with 10-digit accuracy. This corresponds to an energy accuracy of ?E/E=1.16×10-6. The monitoring system for the synthesizer and obtained results are described.

Analysis of the Cyclotron Facility Calibration and Aircraft Results Obtained by LIULIN-3M Instrument  

NASA Technical Reports Server (NTRS)

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.

Calculations and first results obtained with a SiC prototype of the SPES direct target  

NASA Astrophysics Data System (ADS)

In the framework of the SPES project at LNL [A. Bracco, A. Pisent (Ed.), REP 181/02, LNL-INFN, 2002], the realization of a direct ISOL Target for a mid-term radioactive ion beam facility is in progress. Using a primary proton beam of energy 40 MeV and intensity 0.2 mA, a high number of fission products will be obtained in the SPES multi-foil uranium carbide target, keeping a low power density deposition in the refractory matrix [A. Andrighetto, S. Cevolani, C. Petrovich, Eur. Phys J. A 25 (2005) 41]. The exotic species produced by Uranium fission in the target are collected in the ion source after the diffusion and the effusion processes. When short lived isotopes are produced it is very important to optimize the release properties of the target. To this purpose the RIBO code (radioactive ion beam optimiser) [M. Santana Leitner, A Monte Carlo Code to Optimize the Production of Radioactive Ion Beams by the ISOL Technique, PhD. Thesis, UPC-ETSEIB/CERN] has been used in order to estimate the target release efficiency for some neutron-rich nuclei. A SiC prototype of the target was recently produced at LNL and tested at ORNL using a 42 MeV proton beam. The yield of some aluminum isotopes was measured as a function of the target temperature. Some preliminary results of the data analysis will be presented.

Macromolecular crystallographic results obtained at CHESS using a detector incorporating a charge-coupled device  

SciTech Connect

Results from various macromolecular crystallography experiments are presented showing the effectiveness of a recently installed detector incorporating a charge-coupled device (CCD). This detector uses a 1024[times]1024 CCD directly coupled to an x-ray sensitive phosphor by a fiber optic taper. The pixel size at the phosphor (50 [mu]m) results in a point spread of 80 [mu]m full width at half-maximum. Even with the relatively small active area, 51[times]51 mm[sup 2], about 150 orders of diffraction can be resolved across the detector face. With this detector format, well-resolved diffraction data have been collected from unit cells with edges as large as 360 A. In an offset configuration, the detector has been used to collect extremely high-resolution data (1 A). A number of data sets have been collected having [ital R][sub sym] values in the 4%--6% range; in the case of room-temperature lysozyme, an [ital R][sub sym] value as small as 2.1 was obtained for a 2.5 A resolution data set. In addition to fixed wavelength studies, the detector has also been used to collect MAD data. In all cases, the use of this detector has proven to be more efficient than using standard image plates since less x-ray exposure time and no distinct scanning step are required. Furthermore, the data quality is as good and in some cases better than those from previous image plate measurements.

Osteochondritis dissecans of the elbow: excellent mid-term follow-up results in teenage athletes treated by arthroscopic debridement and microfracture  

PubMed Central

Aim To extend the microfracture procedure, which has been proven successful on osteochondritis dissecans (OCD) lesions in the knee and ankle, to OCD lesions in the elbow. Methods Nine young patients were treated by arthroscopic debridement and microfracture by a single surgeon. The average age at operation was 15.0 years (median 15; range 12-19). The average length of the follow-up was 5.3 years (median 5; range 2-9). The follow-up included physical examination and patient interview with elbow function scoring. Success of treatment was determined according to pre-operative and follow-up Mayo Elbow Performance Index scores and the patients’ return to sports. Results Eight patients scored excellent results on the follow-up and 1 scored a good result. Four out of 9 patients were able to increase their training intensity, 2 returned to the same level of activity, 2 changed sports (due to reasons unrelated to the health of their elbow), and 1 left professional sports and started training only recreationally. No patients stopped participating in sports altogether. Conclusions We advocate arthroscopic microfracturing, followed by a strict rehabilitation regime, as a highly effective treatment for OCD of the humeral capitellum.

Remanence anisotropy effect on the palaeointensity results obtained from various archaeological materials, excluding pottery  

NASA Astrophysics Data System (ADS)

The effect of magnetic anisotropy on the palaeointensity results has been evaluated in different materials, including samples from archaeological structures of various ages, such as baked clay from prehistoric domestic ovens or pottery kilns, burnt soil from ancient fires, and bricks and bricks or tiles used in the kiln's construction. The remanence anisotropy was estimated by the thermoremanent (TRM) anisotropy tensor and isothermal remanence (IRM) tensor methods. The small anisotropy effect (less than 5%) observed in the palaeointensity results of baked clay from the relatively thin prehistoric oven's floors estimated previously through IRM anisotropy was confirmed by TRM anisotropy of this material. The new results demonstrate the possibility of using IRM anisotropy evaluation to correct baked clay palaeointensity data instead of the more difficult to determine TRM anisotropy ellipsoid. This is not always the case for the palaeointensity results from bricks and tiles. The anisotropy correction to palaeointensity results seems negligible for materials other than pottery. It would therefore appear that the palaeointensity determination is more sensitive to the degree of remanence anisotropy P and the angle between the natural remanent magnetization (NRM) vector and the laboratory field direction, than to the angle between the NRM and the maximum axis of the remanence anisotropy ellipsoid (Kmax).

Results obtained with the Tropospheric Ozone DIAL System Using a YAG Laser and Raman Cells  

NASA Astrophysics Data System (ADS)

This poster will detail the findings of the ground based Differential Absorption Lidar (DIAL) system built and operated at the NASA Goddard Space Flight Center (Beltsville, MD 38.99° N, 76.84° W) in 2012. Current atmospheric satellites cannot peer through the optically thick stratospheric ozone layer to remotely sense boundary layer tropospheric ozone. In order to monitor this lower ozone more effectively, NASA has funded the ground based Tropospheric Ozone Lidar Network (TOLNET) which currently consists of five stations across the US. The Goddard instrument is based on the Differential Absorption Lidar (DIAL) technique, and has initially transmitted two wavelengths, 289 and 299 nm. Ozone is absorbed more strongly at 289 nm than at 299 nm, and the DIAL technique exploits this difference between the two returned signals to obtain the ozone number density as a function of altitude. The transmitted wavelengths are generated by focusing the output of a quadrupled Nd:YAG laser beam (266 nm) into a pair of Raman Cells, filled with high pressure Hydrogen and Deuterium. Stimulated Raman Scattering within the focus shifts the pump wavelength, and the first Stokes shift in each cell produces the required wavelengths. With the knowledge of the ozone absorption coefficient at these two wavelengths, the vertical number density can then be derived. There are currently surface ozone measurements hourly and ozonesonde launches occasionally, but this system will be the first to make long term ozone profile measurements in the Washington, DC - Baltimore area.

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

NASA Technical Reports Server (NTRS)

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.

Macromolecular crystallographic results obtained using a 2048{times}2048 CCD detector at CHESS  

SciTech Connect

We present results of macromolecular crystallographic experiments performed at the Cornell High Energy Synchrotron Source (CHESS) with a new CCD-based detector. This detector, installed in January 1995, complements a 1024{times}1024 CCD detector that has been in continuous operation at CHESS since December 1993. The new detector is based on a 4-port, 2048{times}2048 pixel CCD that is directly coupled to a Gd{sub 2}O{sub 2}S:Tb phosphor by a 3:1 tapered fiber optic. The active area of the phosphor is a square 82 mm on an edge. The readout time is 7 seconds. In the standard mode of operation, the pixel size at the active area is 41 {mu}m on the edge leading to the capability of resolving approximately 200 orders of diffraction across the detector face. The detector also operates in a 1024{times}1024 mode in which the pixel size is electronically increased by a factor of 4 in area resulting in smaller data files and faster detector readout but at the expense of spatial resolution. Most of the data that has been collected by this detector has been collected in this mode. Dozens of data sets have been collected by many experimenters using this detector at CHESS during the four month period from its installation until the start of the six-month down period of the storage ring. The capabilities of the detector will be illustrated with results from various crystallographic measurements including experiments in which the recorded diffraction patterns extend in resolution as far as 1 A. The results demonstrate that this detector is capable of collecting data of quality at least equal to that of imaging plates but, in many circumstances, with much greater beamline efficiency. {copyright} {ital 1996 American Institute of Physics.}

Hip arthroplasty in patients younger than 30 years: excellent ten to 16-year follow-up results with a HA-coated stem  

PubMed Central

It is well accepted that youth and high activity levels are among the factors that increase the risk of mechanical failure of total hip prostheses. However, there are few reports of long-term results in very young patients. In this study, we evaluated the results of total 49 hip replacements (THRs) using an uncemented total hip prosthesis in 44 patients (28 females) who were 30 years or younger (range: 15–30 years). The diagnosis was ostearthritis due to congenital dislocations in 28 patients, with the remaining patients having diagnoses of sequelae of fracture, infection, Calve-Legg-Perthes disease, avascular necrosis, chondrodystrophia and epiphyseal dysplasia. In all cases we used an uncemented straight stem fully coated with hydroxyapatite (HA). In 36 cases we used a hemispherical cup inserted with press fit, and in seven cases we used a hemispherical screw cup. The patients were evaluated ten to 16 years (mean: 13 years) after the operation by radiographic and clinical examinations, including the Harris Hip, WOMAC and EuroQol-5D scores. In a sub-group of nine patients with a unilateral prosthesis, the muscle strength of the quadriceps and hamstrings was tested using a Cybex 6000. None of the stems were revised at the follow-up examination, and all were classified as well integrated, with no signs of radiological loosening. Twenty-four hips had revision of the acetabular component due to mechanical failure. The Harris Hip score was, on average, 88 (range: 62–100), the WOMAC score 80 (range: 37–100) and the EuroQol score 0.68 (range: ?0.14–1). Isokinetic muscle strength testing showed that seven of the nine tested patients were weaker on the operated side. In conclusion, we found mechanical failures at the acetabular side, but excellent results with a fully HA-coated femoral stem, with no revisions after ten to 16 years.

Revision hip arthroplasty with an extensively ?porous-coated stem - excellent long-term ?results also in severe femoral bone stock loss.  

PubMed

During the last 25 years uncemented hip stem revision relying on diaphyseal fixation has shown improving clinical results and stem survival. The purpose of this study was to present the long-term results of hip revision with the SOLUTION stem (DePuy, Warsaw Indiana).?Ninety-three consecutive SOLUTION hip stem revisions in 84 patients with a mean age of 69 years (range 33-86 years) were reviewed. Of these, clinical and radiographic follow-up examination by an independent observer was possible in 36 hips/29 patients after mean 14 years (range 10-18 years). Stem re-revision was documented by our own files and by the Danish Hip Arthroplasty Registry. ?Stem re-revision had been performed in two hips for aseptic loosening, one due to deep infection and in one patient due to stem fracture. The 18 years cumulative survival, free of re-revision for any reason was calculated as 94.4% (88.9-99.8)% and for aseptic loosening to 97.6% (94.3-100%). Intraoperative complications were frequent with incidence of shaft fractures (14/93) and perforations (9/93) showing a significant learning curve. Mean Harris Hip Score was 85 (range 53-99). Osseointegration was seen in 34/36 stems with two stems fibrous fixated. Stress shielding was significant associated with stem diameters ?15 mm. Severe preoperative bone deficiency had no negative bearing on stem survival and no significant influence on osseointegration of the stem or on Harris Hip Score. ?Conclusion: Femoral stem revision with an extensively porous-coated monoblock chrome-cobalt stem seems to be a reliable and reproducible technique resulting in excellent long-term survivorship and clinical outcome. It can be used in femurs with deficient bone stock. PMID:23813156

Aircrew Exposure To Cosmic Radiation Evaluated By Means Of Several Methods; Results Obtained In 2006  

SciTech Connect

Routine evaluation of aircraft crew exposure to cosmic radiation in the Czech Republic is performed by means of calculation method. Measurements onboard aircraft work as a control tool of the routine method, as well as a possibility of comparison of results measured by means of several methods. The following methods were used in 2006: (1) mobile dosimetry unit (MDU) type Liulin--a spectrometer of energy deposited in Si-detector; (2) two types of LET spectrometers based on the chemically etched track detectors (TED); (3) two types of thermoluminescent detectors; and (4) two calculation methods. MDU represents currently one of the most reliable equipments for evaluation of the aircraft crew exposure to cosmic radiation. It is an active device which measures total energy depositions (E{sub dep}) in the semiconductor unit, and, after appropriate calibration, is able to give a separate estimation for non-neutron and neutron-like components of H*(10). This contribution consists mostly of results acquired by means of this equipment; measurements with passive detectors and calculations are mentioned because of comparison. Reasonably good agreement of all data sets could be stated.

Preliminary Results Obtained in Integrated Safety Analysis of NASA Aviation Safety Program Technologies  

NASA Technical Reports Server (NTRS)

The goal of the NASA Aviation Safety Program (AvSP) is to develop and demonstrate technologies that contribute to a reduction in the aviation fatal accident rate by a factor of 5 by the year 2007 and by a factor of 10 by the year 2022. Integrated safety analysis of day-to-day operations and risks within those operations will provide an understanding of the Aviation Safety Program portfolio. Safety benefits analyses are currently being conducted. Preliminary results for the Synthetic Vision Systems (SVS) and Weather Accident Prevention (WxAP) projects of the AvSP have been completed by the Logistics Management Institute under a contract with the NASA Glenn Research Center. These analyses include both a reliability analysis and a computer simulation model. The integrated safety analysis method comprises two principal components: a reliability model and a simulation model. In the reliability model, the results indicate how different technologies and systems will perform in normal, degraded, and failed modes of operation. In the simulation, an operational scenario is modeled. The primary purpose of the SVS project is to improve safety by providing visual-flightlike situation awareness during instrument conditions. The current analyses are an estimate of the benefits of SVS in avoiding controlled flight into terrain. The scenario modeled has an aircraft flying directly toward a terrain feature. When the flight crew determines that the aircraft is headed toward an obstruction, the aircraft executes a level turn at speed. The simulation is ended when the aircraft completes the turn.

Using the Viking biology experimental results to obtain chemical information about Martian regolith  

NASA Technical Reports Server (NTRS)

Although initially formulated as biology experiments, most of the results produced by the Viking Labeled Release (LR), Gas Exchange (GEX), and Pyrolytic Release (PR) experiments have been reproduced by chemical means. The experiments do not need more study as 'biological' phenomena, but they do deserve much more careful consideration from a chemical viewpoint. They are the only 'wet-chemical' experiments that scientists have performed on another planet, but they have not found very general use as sources of scientific information. There is a large set of potentially useful chemical observations, e.g., the three resolvable and precisely measured kinetic components of the release of C-14-labeled gases, the thermal sensitivity and magnitudes of the oxidation reaction(s) of the LR experiments, the kinetics and magnitude of the O2 and CO2 release of the GEX experiments, the thermal sensitivity of the GEX results, the differences between the thermal sensitivity of the GEX and the thermal sensitivity of the LR responses, and the kinetics and magnitudes of the LR successive injection reabsorption effect. It should be possible to test many chemical aspects of hypothetical martian phenomena in experiments using the biology experimental configurations and derive much valuable information by comparisons with the Viking observations.

Comparison of BOD results obtained by dilution and manometric methods in sanitary landfill leachates.  

PubMed

This study examined the determination of BOD in landfill leachates by dilution (D-method) and manometric methods (M-method). The differences in results were discussed based on statistical tests. The effects of sample dilution, seeding, chloride and total Kjeldahl nitrogen (TKN) level were examined. The M-method was found to be more sensitive to increases in chloride and TKN concentrations. However, in the M-method the positive interference of nitrogenous BOD (NBOD) to carbonaceous BOD (CBOD) was more successfully prevented. The BOD rate constant k and the ultimate BOD (BODu) were estimated by non-linear regression. With the M-method these parameters could be more reliably estimated than the D-method. Suggestions were made for BOD analyses in landfill leachates in future studies. PMID:11296752

Gravity Changes and Internal Processes: Some Results Obtained from Observations at Three Volcanoes  

NASA Astrophysics Data System (ADS)

Temporal gravity changes provide information about mass and/or density variations within and below the volcano edifice. Three active volcanoes have been under investigation; each of them related to a plate boundary: Mayon/Luzon/Philippines, Merapi/Java/Indonesia, and Galeras/Colombia. The observed gravity changes are smaller than previously expected but significant. For the three volcanoes under investigation, and within the observation period, mainly the increase of gravity is observed, ranging from 1,000 nm-2 to 1,600 nms-2. Unexpectedly, the gravity increase is confined to a rather small area with radii of 5 to 8 km around the summit. At Mayon and Merapi the parallel GPS measurements yield no significant elevation changes. This is crucial for the interpretation, as the internal pressure variations do not lead to significant deformation at the surface. Thus the classical Mogi-model for a shallow extending magma reservoir cannot apply. To confine the possible models, the attraction due to changes of groundwater level or soil moisture is estimated along the slope of Merapi exemplarily by 2-D modelling. Mass redistribution or density changes were evaluated within the vent as well as deeper fluid processes to explain the gravity variations; the results are compared to the model incorporating the additional effect of elastic deformation.

Latest results of SEE measurements obtained by the STRURED demonstrator ASIC  

NASA Astrophysics Data System (ADS)

With the perspective to develop a radiation-tolerant circuit for High Energy Physics (HEP) applications, a test digital ASIC VLSI chip, called STRURED, has been designed and fabricated using a standard-cell library of commercial 130 nm CMOS technology by implementing three different radiation-tolerant architectures (Hamming, Triple Modular Redundancy and Triple Time Redundancy) in order to correct circuit malfunctions induced by the occurrence of Soft Errors (SEs). SEs are one of the main reasons of failures affecting electronic digital circuits operating in harsh radiation environments, such as in experiments performed at HEP colliders or in apparatus to be operated in space. In this paper we present and discuss the latest results of SE cross-section measurements performed using the STRURED digital device, exposed to high energy heavy ions at the SIRAD irradiation facility of the INFN National Laboratories of Legnaro (Padova, Italy). In particular the different behaviors of the input part and the core of the three radiation-tolerant architectures are analyzed in detail.

Results from CrIS-ATMS Obtained Using the AIRS Science Team Retrieval Methodology  

NASA Technical Reports Server (NTRS)

AIRS was launched on EOS Aqua in May 2002, together with AMSU-A and HSB (which subsequently failed early in the mission), to form a next generation polar orbiting infrared and microwave atmospheric sounding system. AIRS/AMSU had two primary objectives. The first objective was to provide real-time data products available for use by the operational Numerical Weather Prediction Centers in a data assimilation mode to improve the skill of their subsequent forecasts. The second objective was to provide accurate unbiased sounding products with good spatial coverage that are used to generate stable multi-year climate data sets to study the earth's interannual variability, climate processes, and possibly long-term trends. AIRS/AMSU data for all time periods are now being processed using the state of the art AIRS Science Team Version-6 retrieval methodology. The Suomi-NPP mission was launched in October 2011 as part of a sequence of Low Earth Orbiting satellite missions under the "Joint Polar Satellite System" (JPSS). NPP carries CrIS and ATMS, which are advanced infra-red and microwave atmospheric sounders that were designed as follow-ons to the AIRS and AMSU instruments. The main objective of this work is to assess whether CrIS/ATMS will be an adequate replacement for AIRS/AMSU from the perspective of the generation of accurate and consistent long term climate data records, or if improved instruments should be developed for future flight. It is critical for CrIS/ATMS to be processed using an algorithm similar to, or at least comparable to, AIRS Version-6 before such an assessment can be made. We have been conducting research to optimize products derived from CrIS/ATMS observations using a scientific approach analogous to the AIRS Version-6 retrieval algorithm. Our latest research uses Version-5.70 of the CrIS/ATMS retrieval algorithm, which is otherwise analogous to AIRS Version-6, but does not yet contain the benefit of use of a Neural-Net first guess start-up system which significantly improved results of AIRS Version-6. Version-5.70 CrIS/ATMS temperature profile and surface skin temperature retrievals are of very good quality, and are better than AIRS Version-5 retrievals, but are still significantly poorer than those of AIRS Version-6. CrIS/ATMS retrievals should improve when a Neural-Net start-up system is ready for use. We also examined CrIS/ATMS retrievals generated by NOAA using their NUCAPS retrieval algorithm, which is based on earlier versions of the AIRS Science Team retrieval algorithms. We show that the NUCAPS algorithm as currently configured is not well suited for climate monitoring purposes.

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

PubMed Central

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

Elements of Engineering Excellence  

NASA Technical Reports Server (NTRS)

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.

New high-definition thickness data obtained at tropical glaciers: preliminary results from Antisana volcano (Ecuador) using GPR prospection  

NASA Astrophysics Data System (ADS)

The study of tropical glaciers has been a significant contribution to the understanding of glacier dynamics and climate change. Much of the data and results have been obtained by analyzing plan-view images obtained by air- and space-borne sensors, as well as depth data obtained by diverse methodologies at selected points on the glacier surface. However, the measurement of glacier thicknesses has remained an elusive task in tropical glaciers, often located in rough terrains where the application of geophysical surveys (i.e. seismic surveys) requires logistics sometimes hardly justified by the amount of obtained data. In the case of Ecuador, however, where most glaciers have developed on active volcanoes and represent sources/reservoirs of fresh water, the precise knowledge of such information is fundamental for scientific research but also in order to better assess key aspects for the society. The relatively recent but fast development of the GPR technology has helped to obtain new highdefinition thickness data at Antisana volcano that will be used to: 1) better understand the dynamics and fate of tropical glaciers; 2) better estimate the amount of fresh water stored in the glaciers; 3) better assess the hazards associated with the sudden widespread melting of glaciers during volcanic eruptions. The measurements have been obtained at glaciers 12 and 15 of Antisana volcano, with the help of a commercial GPR equipped with a 25 MHz antenna. A total of 30 transects have been obtained, covering a distance of more than 3 km, from the glacier ablation zone, located at ~ 4600 masl, up to the level of 5200 masl. The preliminary results show a positive correlation between altitude and glacier thickness, with maximum and minimum calculated values reaching up to 80 m, and down to 15 m, respectively. The experience gained at Antisana volcano will be used to prepare a more widespread GPR survey in the glaciers of Cotopaxi volcano, whose implications in terms of volcanic hazards are largely more significant. Other ice-cladded ecuadorian volcanoes, like Cayambe or Chimborazo, could also be considered in future research..

An assembly of soft x-ray pulse height analyzer system, based on silicon drift detector (SDD), has been successfully established on the experimental advanced superconducting tokamak (EAST) to measure the spectrum of soft x-ray emission (E=1-20 keV). The system, including one 15-channel SDD linear array, is installed on EAST horizontal port C. The time-resolved radial profiles of electron temperature and K(alpha) intensities of metallic impurities have been obtained with a spatial resolution of around 7 cm during a single discharge. It was found that the electron temperatures derived from the system are in good agreement with the values from Thomson scattering measurements. The system can also be applied to the measurement of the long pulse discharge for EAST. The diagnostic system is introduced and some typical experimental results obtained from the system are also presented. PMID:20590235

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

PubMed Central

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.

Remnant Preservation is Helpful to Obtain Good Clinical Results in Posterior Cruciate Ligament Reconstruction: Comparison of Clinical Results of Three Techniques  

PubMed Central

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.

Quantitating heart lipids: comparison of results obtained using the Iatroscan method with those from phosphorus and gas chromatographic techniques.  

PubMed

The precision and accuracy of the Iatroscan method was evaluated by comparing the results obtained with established phosphorus and gas chromatographic techniques. A complete lipid class analysis of rat heart lipids was chosen in order to evaluate the performance of the Iatroscan method for biological samples which contained both neutral lipids and phospholipids. A partial scan and repeat development with chloroform/methanol/water (68.5:29:2.5) was introduced to achieve consistently good separations of the phospholipids on the Chromarods in the Iatroscan method. The results showed that the precision of the Iatroscan method for some lipid classes was comparable to that of phosphorus or gas chromatographic techniques, while for other lipid classes it was lower. Compared to the data obtained using the phosphorus method, the Iatroscan data were generally similar, while the gas chromatographic method generally gave lower values. These findings, together with the advantages of time required for analysis, size of sample, and universality of detection, suggest that the Iatroscan is a valuable complementary method for complex lipid analyses.

Analysis of the results obtained using a technic of experimental primary infestation with Fasciola hepatica in the rat.  

PubMed

In this work, we analyzed the results obtained using a technic of infestation with Fasciola hepatica in the rat. The infestations were carried out with 30 metacercariae in a gelatin capsule. The humoral immune response, measured by ELISA, and the liver necroses, spleen size, number and length of the flukes recovered at necropsy were followed during the course of four experimental primary infestations. The results showed that the magnitude of the parasitic burden did not correlate with the humoral immune response of the rat. The study of the liver necroses, spleen size, fluke length and antibody titres showed that the use of 30 metacercariae in a capsule as a technic of infestation in the rat ensured the homogeneity of the parasite development and the humoral immune response of the host.

Costas loop demodulation of suppressed carrier BPSK signals in the DSN environment: Experimental results obtained at TDL  

NASA Technical Reports Server (NTRS)

Suppressed carrier binary phase-shift keyed (BPSK) signalling is currently being considered as a design alternative for future DSN telemetry in the multimegabit range. Carrier tracking of such signals is usually achieved by a Costas loop, as opposed to the ordinary phase lock loop. A Costas loop capable of demodulating BPSK signals with data rates up to 1 Msps was designed and constructed and its Doppler tracking performance with respect to a Block 3 receiver was tested at the Telecommunications Development Laboratory (TDL). The compatibility of suppressed carrier signalling with the current radiometric system, specifically Doppler tracking and ranging, was investigated. The experimental results obtained to-date with respect to Doppler tracking are presented.

An improved procedure for low-temperature embedding of high-pressure frozen and freeze-substituted plant tissues resulting in excellent structural preservation and contrast.  

PubMed

Here we describe refinements in the processing of high-pressure frozen samples of delicate plant tissues for immuno-electron microscopy. These involve: shortened freeze-substitution schedules, lower temperatures during processing and polymerisation, the avoidance of temperature fluctuations and the optimisation of heat transfer from the specimens using small disposable aluminium containers. The application of these modifications leads to very good structural preservation and selective membrane contrast. As a result, the versatility of the method is increased since not only immuno-electron microscopical studies can be performed but often the quality is also quite suitable for structural investigations.

Standardization of a fluconazole bioassay and correlation of results with those obtained by high-pressure liquid chromatography.  

PubMed Central

An improved bioassay for fluconazole was developed. This assay is sensitive in the clinically relevant range (2 to 40 micrograms/ml) and analyzes plasma, serum, and cerebrospinal fluid specimens; bioassay results correlate with results obtained by high-pressure liquid chromatography (HPLC). Bioassay and HPLC analyses of spiked plasma, serum, and cerebrospinal fluid samples (run as unknowns) gave good agreement with expected values. Analysis of specimens from patients gave equivalent results by both HPLC and bioassay. HPLC had a lower within-run coefficient of variation (less than 2.5% for HPLC versus less than 11% for bioassay) and a lower between-run coefficient of variation (less than 5% versus less than 12% for bioassay) and was more sensitive (lower limit of detection, 0.1 micrograms/ml [versus 2 micrograms/ml for bioassay]). The bioassay is, however, sufficiently accurate and sensitive for clinical specimens, and its relative simplicity, low sample volume requirement, and low equipment cost should make it the technique of choice for analysis of routine clinical specimens.

Clinical implications of elevated HIV-1 viral load results obtained from samples stored frozen in vacutainer plasma preparation tubes.  

PubMed

Studies have demonstrated that plasma samples collected and stored frozen using vacutainer plasma preparation tubes (PPT) may result in falsely elevated viral load (VL) values with the Roche COBAS TaqMan HIV-1 v1.0 test. At the University of Connecticut Health Center, a total of 349 samples from HIV-1-infected patients on HAART were collected and stored frozen in PPT. Viral load (VL) results were obtained using the Roche COBAS TaqMan HIV-1 v2.0 test (CTM v2.0) and Abbott RealTime HIV-1 assay (RealTime HIV-1). Of the 349 samples, 260 (74.5%) had VL values that differed by >0.5log10copies/mL; 64 of these were quantified by both assays. The remaining 196 samples were detected by CTM v2.0 but not detected in RealTime HIV-1: 62 of the most discordant samples in this category (CTM v2.0 detected/RealTime HIV-1 not detected) were further analyzed using two nested RT-PCR assays targeting pol integrase: full-length (864nt) and a highly conserved subregion (134nt). No HIV-1 RNA was detected in the discordant samples, confirming RealTime HIV-1 results. The increase in VL reactivity with the CTM v2.0 assay was presumably due to proviral DNA captured by the CTM total nucleic acid extraction chemistry but not the RNA-specific extraction procedure used in RealTime HIV-1. These results suggest that using CTM v2.0 with samples frozen in PPT could have significant clinical implications for HIV-1 patient management. PMID:24747107

Real time prediction of sea level anomaly data with the Prognocean system - comparison of results obtained using different prediction techniques  

NASA Astrophysics Data System (ADS)

Prognocean is a near-real time modeling and prediction system elaborated and based at University of Wroclaw, Poland. It operates on gridded Sea Level Anomaly (SLA) data obtained from the Archiving, Validation and Interpretation of Satellite Oceanographic data (AVISO), France. The data acquisition flow from AVISO to Prognocean is entirely automatic and is implemented in Python. The core of the system - including data pre-processing, modeling, prediction, validation and visualization procedures - is composed of a series of R scripts that are interrelated and work at three levels of generalization. The objective of the work presented here is to show the results of our numerical experiment that have been carried out since early 2012. Four prediction models have been implemented to date: (1) extrapolation of polynomial-harmonic model and the extrapolation of polynomial-harmonic model with (2) autoregressive model, (3) threshold autoregressive model and (4) autocovariance procedure. Although the presentation is limited to four models and their predictive skills, Prognocean consists of modules and hence new techniques may be plugged in at any time. In this paper, the comparison of the results into forecasting sea level anomaly maps is presented. Along with sample predictions, with various lead times up to two weeks, we present and discuss a set of root mean square prediction error maps computed in real time after the observations have been available. We identified areas where linear prediction models reveal considerable errors, which may indicate a non-linear mode of sea level change. In addition, we have identified an agreement between the spatial pattern of large prediction errors and the spatial occurrence of key mesoscale ocean eddies.

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

NASA Astrophysics Data System (ADS)

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.

ON THE DIFFERENT ANALYTICAL RESULTS OBTAINED FOR THE PARALLEL DIFFUSION COEFFICIENT OF COSMIC PARTICLES WITH ADIABATIC FOCUSING  

SciTech Connect

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.

NASA Astrophysics Data System (ADS)

Some new results have been observed with the solar decimeter spectrometer with a new observing mode at National Astronomical Observatories (NAOC), Chinese Academy of Sciences (CAS). The temporal resolution and frequency range used in the new observing mode are 1.25 msec and 1.10-1.34 GHz, respectively, while they are 5 msec and 1.10-2.06 GHz, respectively used in the standard observing mode. The spectral resolution is 4 MHz in both observing modes. Some unexpected super-fine structures in narrowband type III bursts (namely "blips"), zebra patterns, fiber bursts, and some new fine structures have been found. The new results will lead to deeply understand the energy release and transfer in the low corona during solar flares.

Thermal monitoring of hydrothermal activity by permanent infrared automatic stations: Results obtained at Solfatara di Pozzuoli, Campi Flegrei (Italy)  

NASA Astrophysics Data System (ADS)

A permanent automatic infrared (IR) station was installed at Solfatara crater, the most active zone of Campi Flegrei caldera. After a positive in situ calibration of the IR camera, we analyze 2175 thermal IR images of the same scene from 2004 to 2007. The scene includes a portion of the steam heated hot soils of Solfatara. The experiment was initiated to detect and quantify temperature changes of the shallow thermal structure of a quiescent volcano such as Solfatara over long periods. Ambient temperature is the main parameter affecting IR temperatures, while air humidity and rain control image quality. A geometric correction of the images was necessary to remove the effects of slow movement of the camera. After a suitable correction the images give a reliable and detailed picture of the temperature changes, over the period October 2004 to January 2007, which suggests that origin of the changes were linked to anthropogenic activity, vegetation growth, and the increase of the flux of hydrothermal fluids in the area of the hottest fumaroles. Two positive temperature anomalies were registered after the occurrence of two seismic swarms which affected the hydrothermal system of Solfatara in October 2005 and October 2006. It is worth noting that these signs were detected in a system characterized by a low level of activity with respect to systems affected by real volcanic crisis where more spectacular results will be expected. Results of the experiment show that this kind of monitoring system can be a suitable tool for volcanic surveillance.

The neurobehavioral impact of manganese: Results and challenges obtained by a meta-analysis of individual participant data  

PubMed Central

Results from a meta-analysis of aggregated data provoked a new analysis using individual data on the neuropsychological performance of occupationally exposed workers. Data from eight studies examining 579 exposed and 433 reference participants were included, 28 performance variables analyzed. The performance scores were adjusted for well-known individual-level covariates; the influence of possible, but unknown study-level covariates was attenuated by means of a z-normalization. Associations between performance and exposure were estimated by ANOVAs and ANCOVAs, the latter representing multi-level models. Four cognitive and motor performance variables each indicated significantly lower performances of exposed individuals when confounding was considered; slowed motor performances and deficits in attention and short-term memory were found. Performance on a single test was significantly related to the biomarker manganese in blood. The outcomes on susceptibility were weak. The slowing of responses was the most distinct feature of performances of exposed workers. It remains unclear, whether this result is related to the employed tests or provides important information about early stages of the neurotoxic impairment. More specific cognitive tests need to be employed to answer this question. The lack of dose–response relationships was related to features of the biomarker: it does not reflect the Mn in brain responsible for changes in performances.

A comparison of the results obtained with traditional phlebotomy and with therapeutic erythrocytapheresis in patients with erythrocytosis  

PubMed Central

Background Phlebotomy is the most commonly treatment used for erythrocytosis and polycythaemia. After the introduction in the medical practice of cell separators, erythrocytapheresis has been also introduced. The aim of the study was to compare the clinical results of the two kinds of treatment. Patients and methods We analysed 98 patients affected by different forms of erythrocytosis, divided into three treatment groups: 1) patients undergoing phlebotomy; 2) patients treated only with therapeutic erythrocytapheresis; 3) patients who underwent phlebotomy treatment for a certain period and who were then switched to apheresis treatment. The haematocrit in these patients was maintained at about 45% and they were treated when the haematocrit exceeded the critical threshold of 50%. Results The interval between two therapeutic interventions was assumed as indicator. In 80% of the patients treated only with phlebotomy the interval was between 20 days and 2 months, in subjects treated with only erythrocytapheresis the intevals were between 2 and 7 months. In the third group of patients, the switch from phlebotomy to erythrocytapheresis considerably prolonged the interval. Conclusions The data showed that erythrocytapheresis was clearly superior to traditional phlebotomy in terms of prolonging the period between one treatment and another, independently of the type of erythrocytosis and of the treatment group.

Results showed a small (5-6 microg l(-1)) but statistically significant difference in mean concentrations for chloride and sulfate but not for nitrate. 2% of the data indicate real differences in concentrations across the ice core. Despite these differences ion information in ice core layers are comparable for ice core paleoclimate and environmental studies even though analyses are made using two different procedures.

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

NASA Astrophysics Data System (ADS)

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.

Mapping The Urban Heat Island Effect In Athens: Results Obtained From The UHI and Thermopolis 2009 Projects  

NASA Astrophysics Data System (ADS)

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.

Electrolytes assessed by point-of-care testing - Are the values comparable with results obtained from the central laboratory?  

PubMed Central

Background and Aims: When dealing with very sick patients, the speed and accuracy of tests to detect metabolic derangements is very important. We evaluated if there was agreement between whole blood electrolytes measured by a point-of-care device and serum electrolytes measured using indirect ion-selective electrodes. Materials and Methods: In this prospective study, electrolytes were analyzed in 44 paired samples drawn from critically ill patients. Whole blood electrolytes were analyzed using a point-of-care blood gas analyzer and serum electrolytes were analyzed in the central laboratory on samples transported through a rapid transit pneumatic system. Agreement was summarized by the mean difference with 95% limits of agreement (LOA) and Lin’s concordance correlation (p c). Results: There was a significant difference in the mean (±standard deviation) sodium value between whole blood and serum samples (135.8 ± 5.7 mmol/L vs. 139.9 ± 5.4 mmol/L, P < 0.001), with the agreement being modest (pc = 0.71; mean difference ?4.0; 95% LOA ?8.78 to 0.65). Although the agreement between whole blood and serum potassium was good (pc = 0.96), and the average difference small (?0.3; 95% LOA ?0.72 to 0.13), individual differences were clinically significant, particularly at lower potassium values. For potassium values <3.0 mmol/L, the concordance was low (pc = 0.53) and the LOA was wide (1.0 to ?0.13). The concordance for potassium was good (pc = 0.96) for values ?3.0 (mean difference ?0.2; 95% LOA ?0.48 to 0.06). Conclusions: Clinicians should be aware of the difference between whole blood and serum electrolytes, particularly when urgent samples are tested at point of care and routine follow-up electrolytes are sent to the central laboratory. A correction factor needs to be determined at each center.

Pyrolysis of mixtures of sewage sludge and manure: a comparison of the results obtained in the laboratory (semi-pilot) and in a pilot plant.  

PubMed

A pilot-scale pyrolysis process was carried out for the treatment of a mixture of two types of waste, sewage sludge and cattle manure, comparing the results with others obtained under laboratory conditions (semi-pilot scale). The aim of this study was to obtain the energetic valorization of the products. Owing to the specific characteristics of the plant, two products were obtained from the process: gas and carbonized solid. As no liquid fraction was obtained, the gas fraction is a greater percentage made up of both condensable and non-condensable compounds, which were obtained separately at the laboratory scale. The pilot plant was designed so that the gases produced by thermolysis were burnt continuously in a combustion chamber, while the carbonized fraction was fed in batches for co-combustion. To determine composition and combustion ability, the gas and solid products from the pilot process were characterized by chromatographic analysis of the gaseous fraction and chemical analysis and programmed-temperature combustion of the carbonized solid. The composition of the combustion gases, rich in light hydrocarbons, and the carbon present in the carbonized fraction enable the energetic valorization of these products. The combustion gases were subjected to a cleaning process and their composition analysed twice: before and after the gas cleaning treatment. The study led to a positive assessment of the possible use of the process products as fuel, provided that the combustion gases are treated. As most of the sulphur and chlorine from the original waste are mainly concentrated in the solid fraction, the use of char as a fuel will depend on the effectiveness of clean-up techniques for combustion gases. During gas cleansing, neutralizing with sodium bicarbonate proved effective, especially for the acidic compounds HCl, HF and SO(2). PMID:16996726

Centers of Excellence: A Catalogue  

NASA Technical Reports Server (NTRS)

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.

College Astronomy Teaching Excellence Workshops  

NASA Astrophysics Data System (ADS)

As part of the education and public outreach efforts of the NASA JPL Navigator, SIRTF Mission and the Astronomical Society of the Pacific, astronomy educators affiliated with the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona are conducting a series of two- and three-day teaching excellence workshops for college faculty. These workshops are being held in conjunction with professional society meetings, such as the American Astronomical Society and the American Association of Physics Teachers, and through the infrastructure of the National Science Foundation's Summer Chautauqua Workshop program. This three-day, interactive teaching excellence workshop focuses on dilemmas astronomy teachers face and develop practical solutions for the troubling issues in curriculum, instruction, and assessment. After reviewing the latest research about how students learn, participants define and set measurable student learning goals and objectives for students in their astronomy courses and construct effective course syllabi reflecting the ASTRO 101 goals publicized by the AAS. To improve instruction, participants learn how to create productive learning environments by using interactive lectures, peer instruction, engaging demonstrations, collaborative groups, tutorials, computer-based laboratories, and observational projects. Participants also learn how to write more effective multiple-choice tests and implement authentic assessment strategies including portfolio assessment, performance tasks, and concept maps. Texts provided at the workshop are: (i) Learner-Centered Astronomy Teaching, Slater and Adams, Prentice Hall, 2002; (ii) Great Ideas for Teaching Astronomy, Pompea, Brooks Cole, 2000; and (iii) Lecture-Tutorials for Introductory Astronomy, Adams, Prather, & Slater, Prentice Hall, 2002.

Factors Associated With Students' Perception of Preceptor Excellence  

PubMed Central

Objectives. To identify factors associated with preceptor excellence as rated by student pharmacists and to assess the correlation of excellent ratings with years as pharmacist, specialty certification, and faculty appointment status. Methods. A retrospective analysis of student pharmacist evaluations of preceptors from May 2009 to May 2012 was completed to determine factors associated with preceptor excellence. Results. Preceptors who showed an interest in teaching, related to the student as an individual, encouraged discussion, were accessible, provided feedback, served as a role model, were organized, and/or spent increased time with students were more likely to be rated excellent. Conclusion. Serving as role models and showing an interest in teaching demonstrated the strongest association with being an excellent preceptor. Identifying factors students associate with preceptor excellence may result in enhanced preceptor recruitment, development, and training.

Understanding Statistical Mechanics and Biophysics Using Excel  

NASA Astrophysics Data System (ADS)

A new approach to teaching statistical mechanics and biophysics is presented using the classic two-box system from statistical mechanics as an example. This approach makes advanced physics concepts accessible to a broad audience including undergraduates with no calculus background. Students develop a simple Excel spreadsheet that implements a kinetic Monte Carlo (kMC) simulation algorithm ``from scratch''. The students discover for themselves the properties of the system by analyzing the simulation output in a directed, activity-based exercise. By changing the number and initial distribution of the particles, students see how the system approaches equilibrium and how system variability changes with system size. A finite difference solution is also implemented in Excel, and students compare its predictions with the kMC results. This approach is quite different from using ``canned'' computer demonstrations, as students design, implement and debug the simulation themselves -- ensuring that they understand the model system intimately.

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.

Interobserver agreement of the injury diagnoses obtained by postmortem computed tomography of traffic fatality victims and a comparison with autopsy results.  

PubMed

The present study investigated the interobserver variation between a radiologist and a forensic pathologist in 994 injury diagnoses obtained by postmortem computed tomography (CT) of 67 traffic fatality victims, and the results were compared with diagnoses obtained by autopsy. The injuries were coded according to the abbreviated injury scale (AIS). We found a low interobserver variability for postmortem CT injury diagnoses, and the variability was the lowest for injuries with a high AIS severity score. The radiologist diagnosed more injuries than the pathologist, especially in the skeletal system, but the pathologist diagnosed more organ injuries. We recommend the use of a radiologist as a consultant for the evaluation of postmortem CT images. Training in radiology should be included in forensic medicine postgraduate training. CT was superior to autopsy in detecting abnormal air accumulations, but autopsy was superior to CT in the detection of organ injuries and aortic ruptures. We recommend a combination of CT and autopsy for the postmortem investigation of traffic fatality victims. PMID:22541590

Academic excellence workshops in chemistry and physics  

NASA Astrophysics Data System (ADS)

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.

Recent results obtained by use of accelerators on plasma-edge properties in controlled-fusion devices and on properties of high-power neutral beams  

SciTech Connect

The study of plasma-wall interactions is of primary importance in present fusion devices. Measurements of incident fuel and impurity fluxes, retention and release of fuel atoms, and erosion of internal components are of particular interest. Accelerators in the megaelectronvolt range are being used both to measure the depth profile of fuel atoms implanted in samples placed in the plasma edge by use of nuclear reactions and to measure impurities and film thicknesses by use of elastic scattering reactions. Secondary ion mass spectrometry (SIMS) is used to determine flux and energy distributions of fuel atoms and to measure species composition and impurities in the beams of high power neutral beam injectors. Recent results obtained with these techniques are presented and areas of future study are discussed.

Reaeration coefficients of six streams in New York; a comparison of results obtained by a hydrocarbon-gas tracer method with those obtained by radioactive tracers and predictive equations  

USGS Publications Warehouse

Stream-reaeration measurements were made in selected reaches on six streams in New York State from 1978 to 1981 with hydrocarbon-gas and dye tracers. The sites were Canadaigua Outlet near Canadaigua, Oswego River at Fulton, Hudson River at Fort Miller, Cayadutta Creek near Johnstown, Chenango River near Morrisville, and Payne Brook near Hamilton. The reaches represent a wide range of discharge, water-surface slope, velocity, and streambed composition. Flows ranged from less than 2 cu ft/sq on the Chenango River to 4,100 cu ft/sq on the Hudson River, and water-surface slope within the reaches ranged from less than 1 foot/mile on the Hudson and Oswego Rivers to more than 50 ft/mi on Cayadutta Creek. The corresponding stream-reaeration coefficients ranged from 0.77 units/day for one reach on Canadaigua Outlet to 52 units/day on Cayadutta Creek. The reaeration coefficients for Canadaigua Outlet compared well with those obtained on the same reach 10 years earlier by radioactive tracers. Comparison of measured reaeration coefficients with those calculated from 10 predictive equations based on stream-channel characteristics yielded mean errors that range from 51% to 103%. No single equation gave reliable accuracy for all stream reaches. (USGS)

Obtaining land cover changes information from multitemporal analysis of Landsat-TM images: results from a case study in West African dryland  

NASA Astrophysics Data System (ADS)

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.

ROBIN: a platform for evaluating automatic target recognition algorithms: II. Protocols used for evaluating algorithms and results obtained on the SAGEM DS database  

NASA Astrophysics Data System (ADS)

Over the five past years, the computer vision community has explored many different avenues of research for Automatic Target Recognition. Noticeable advances have been made and we are now in the situation where large-scale evaluations of ATR technologies have to be carried out, to determine what the limitations of the recently proposed methods are and to determine the best directions for future works. ROBIN, which is a project funded by the French Ministry of Defence and by the French Ministry of Research, has the ambition of being a new reference for benchmarking ATR algorithms in operational contexts. This project, headed by major companies and research centers involved in Computer Vision R&D in the field of Defense (Bertin Technologies, CNES, ECA, DGA, EADS, INRIA, ONERA, MBDA, SAGEM, THALES) recently released a large dataset of several thousands of hand-annotated infrared and RGB images of different targets in different situations. Setting up an evaluation campaign requires us to define, accurately and carefully, sets of data (both for training ATR algorithms and for their evaluation), tasks to be evaluated, and finally protocols and metrics for the evaluation. ROBIN offers interesting contributions to each one of these three points. This paper first describes, justifies and defines the set of functions used in the ROBIN competitions and relevant for evaluating ATR algorithms (Detection, Localization, Recognition and Identification). It also defines the metrics and the protocol used for evaluating these functions. In the second part of the paper, the results obtained by several state-of-the-art algorithms on the SAGEM DS database (a subpart of ROBIN) are presented and discussed

Biomarker based reconstruction of Pleistocene climate and environmental conditions in the Gulf of Alaska: Preliminary results obtained from IODP Expedition 341 sediments  

NASA Astrophysics Data System (ADS)

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).

Simplifying CEA through Excel, VBA, and Subeq  

NASA Technical Reports Server (NTRS)

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.

Results of regular study on radionuclidic purity of 99mTc obtained from 99Mo--99mTc generators.  

PubMed

A total of 39 99mTc eluates obtained from 9 99Mo--99mTc generators delivered by The Radiochemical Centre Amersham during one year was studied with regard to their radionuclide purity. Using a Ge(Li) spectrometer the contaminants 60Co, 103Ru, 131I, 134Cs, 140Ba, 140La and 188Re were found in 99mTc-eluates with average levels ranging from 2.9 X 10(-3) to 2.8 X 10(-1) per cent of 99mTc activity. The additional total body absorbed dose caused by these contaminants, as calculated from their average content in 99mTc eluates, was less than 1% of the dose due to 99mTc pertechnetate. PMID:520349

Biosensors for monitoring the isothermal breakdown kinetics of peanut oil heated at 180°C. Comparison with results obtained for extra virgin olive oil.  

PubMed

The present research was devoted to studying the kinetics of the artificial rancidification of peanut oil (PO) when a sample of this oil was isothermally heated at 180°C in an air stream. The formation of radical species due to heating was evaluated using a radical index whose value was determined using a biosensor method based on a superoxide dismutase (SOD), while the increasing toxicity was monitored using a suitable toxicity measuring probe based on the Clark electrode and immobilized yeast cells. An extra virgin olive oil was isothermally rancidified under the same experimental conditions and the corresponding data were used for the purpose of comparison. Both the so-called "model-fitting" and the classical kinetic methods were applied to the isothermal process biosensor data in order to obtain the kinetic constant rate value at 180°C. PMID:23692756

BREEAM Excellent: Business Value Vs Employee Morale  

NASA Astrophysics Data System (ADS)

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.

Achieving excellence through organizational values.  

PubMed

By focusing on its mission values, a hospital can enhance the quality of patient care, improve staff morale, promote cost-effectiveness, and achieve a competitive advantage in the hospital marketplace. Since 1979 Saint Joseph Hospital, Kansas City, MO, has conducted a project to clarify and apply its values to the organization's overall direction and the everyday work setting. The project has proven that a concentration on mission values can benefit both the hospital's basic "spirit" and its bottom line. Twelve guiding principles are essential to creating a values-focused hospital: 1. Begin with a commitment. 2. Identify, involve, and educate "stakeholders". 3. Identify and use appropriate resources. 4. Assess organizational needs. 5. Identify the organization's values. 6. Translate mission values into everyday language. 7. Use an explicit, visible process built with a core set of process tools. 8. Document and showcase results. 9. Link the values work to the organization's overall direction and goals and to day-to-day management issues. 10. Think and act strategically. 11. Weave values focus into the fabric of the organization to ensure permanence and long-term success. 12. Model behavior on values. PMID:10275601

Toxic Metal Concentrations in Cigarettes Obtained from U.S. Smokers in 2009: Results from the International Tobacco Control (ITC) United States Survey Cohort  

PubMed Central

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.

Results and interpretation of groundwater data obtained from multiport-instrumented coreholes (GW-131 through GS-135), fiscal years 1990 and 1991  

SciTech Connect

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.

Clinical Excellence in Psychiatry: A Review of the Psychiatric Literature  

PubMed Central

Objective: The provision of excellent patient care is a goal that physicians would like to achieve in caring for all patients, all of the time. 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.

The end-product method of measuring whole-body protein turnover: a review of published results and a comparison with those obtained by leucine infusion.  

PubMed

The present review summarizes the results of all published papers on whole-body protein turnover in man measured by [15N]glycine and the end-product method using both urea and ammonia. It begins with a short account of the underlying assumptions and the justification for the use of [15N]glycine. The results are then compared with those of a large sample of measurements by the 'gold standard' precursor method with continuous infusion of [13C]leucine. The pros and cons of the two methods are compared and it is suggested that there is a place for further work by the less invasive end-product method, particularly for population studies of the genetic, environmental and functional determinants of whole-body rates of protein synthesis.

Spinning characteristics of the XN2Y-1 airplane obtained from the spinning balance and compared with results from the spinning tunnel and from flight tests  

NASA Technical Reports Server (NTRS)

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.

A cross-cultural study on noise problems: Comparison of the results obtained in Japan, West Germany, the U.S.A., China and Turkey  

NASA Astrophysics Data System (ADS)

Neighborhood noise has become a serious problem in many countries, and it is difficult to regulate by physical means alone. A cross-cultural survey was conducted in five countries, Japan, West Germany, the United States, China and Turkey, among residents of apartment houses in order to examine the cultural differences involved. Interesting differences were found in preferred countermeasures, highly annoying sounds, attitudes against noise, expectations for laws, etc. The use of loudspeakers in public places was accepted in all five countries, provided that they were used for conveying necessary information. The results suggest that it is important to take cultural or social backgrounds into consideration in order to find suitable countermeasures.

Comparison of results obtained by solving the radiative transfer equation with an iterative method and a spherical harmonics method. [atmospheric light scattering computation  

NASA Technical Reports Server (NTRS)

Fluxes and intensities of light scattered by a model atmosphere are computed by a spherical harmonics approximation and by an iterative method of solving the radiative transfer equation and are compared. The large differences in the net fluxes and intensities reported by Dave and Armstrong (1974) for the two methods are reduced here by making a few changes in the iterative routine. Decreasing the polar angle increment from 2 to 1 deg in the iterative method of computing the source function does not improve the results as suggested by Dave and Armstrong.

[Comparison of the results obtained using 99mTc HM-PAO tomoscintigraphy and computer tomography in ischemic lesions of the brain].  

PubMed

Fifty patients suffering from cerebral ischemic attacks, transient or not, were studied with both 99mTc HM-PAO single photon emission computed tomography (SPECT) and computed tomography (CT). In 31 patients both SPECT and CT showed pathologic areas, the max diameters of which were measured on CT images and SPECT orbitomeatal reconstructed sections, and then compared. We observed that: only SPECT images are positive for pathologic conditions in transient ischemic attacks and in the very early phases of infarctions; in recent infarctions (less than 15 days earlier) both SPECT and CT scans are positive but SPECT lesion areas are greater than CT ones; pathologic areas, with clear-cut outlines, having the same dimensions on both CT and SPECT images, are supposed to result from old static infarctions. A persistent perilesional hypoactive area on SPECT images means, in our opinion, a hypoperfusional area liable to new vascular troubles; in which case, medical/surgical therapy seems necessary.

[Reliability of the diagnostic results obtained with confined quantities of the contrast medium in endolymphatic radionuclide therapy (ELRT) of the inferior limbs (author's transl)].  

PubMed

Endolymphatic radionuclide therapy (ELRT) produces not only a radiotherapeutic effect on the lymph nodes but makes possible also to judge of the lymph nodes being stained with labelled lipiodol UF. With the purpose of avoiding an eventual radiation exposure of the lung, or at least of confining it to a minimum, only limited quantities not exceeding 3.5 ml (5 mCi of 32P; 0.5 mCi of 131I) of the oily contrast medium for unilateral, or twice 3.5 ml (together 4 mCi of 32P; 0.5 mCi of 131I) for bilateral application. A retrospective analysis of 245 patients of the study group for endolymphatic radionuclide therapy, who suffered from malignant melanomas of the inferior limbs, revealed 77.5% of correct diagnoses. Most of the false-positive findings (44/70) seem to be due to the knowledge of the primary disease, as 77% of these cases had been described as "suspicious". False-negative findings turned out in 5% only. The findings which had been characterized as "surely positive" proved reliable in 90%. The good results of lymphography with smaller quantities of the contrast medium are, on the whole, comparable to those of primary diagnostic lymphography. PMID:7414647

Results of the new processing of images obtained from the surface of Venus in a TV experiment onboard the VENERA-9 lander (1975)  

NASA Astrophysics Data System (ADS)

Data on the results of the analysis of the content of re-processed panorama of the VENERA-9 lander are presented. The panorama was transmitted historically for the first time from the surface of Venus in 1975. The low noise of the VENERA-9 data allowed allocating a large object of an unusual regular structure. Earlier, its fuzzy image was repeatedly cited in the literature being interpreted as a "strange stone". The complex shape and its other features suggest that the object may be a real habitant of the planet. It is not excluded that another similar object observed was damaged during the VENERA-9 landing. From the evidence of its movement and position of some other similar objects it is concluded that because of the limited energy capacity, the physical action of the Venusian fauna may be much slower than that of the Earth fauna. Another question considered is what sources of energy could be used by life in the conditions of the high temperature oxygenless atmosphere of the planet. It is natural to assume that, like on Earth, the Venusian fauna is heterotrophic and should be based on hypothetical flora, using photosynthesis (based on an unknown high temperature biophysical mechanism).

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.

A new class of gadolinium complexes employed to obtain high-phasing-power heavy-atom derivatives: results from SAD experiments with hen egg-white lysozyme and urate oxidase from Aspergillus flavus.  

PubMed

Seven gadolinium complexes are shown to be excellent compounds for the preparation of heavy-atom derivatives for macromolecular crystallography projects. De novo phasing has been carried out using single-wavelength anomalous diffraction (SAD) on a series of gadolinium-derivative crystals of two proteins: hen egg-white lysozyme and urate oxidase from Aspergillus flavus. Lysozyme derivative crystals were obtained by co-crystallizing the protein with the corresponding gadolinium complex at a concentration of 100 mM. Diffraction data were collected to a resolution of 1.7 A using Cu K(alpha) radiation from a rotating-anode generator, making use of the high anomalous signal of gadolinium at this wavelength. Urate oxidase derivative crystals were obtained by soaking native crystals in 100 mM gadolinium complex solutions. Diffraction data were collected to a resolution close to 3 A using X-rays at the Gd L(III) absorption edge, taking advantage of the sharp white line on that edge. For all urate oxidase derivative crystals and three of the lysozyme crystals, SAD phasing led to electron-density maps of very high quality, allowing unambiguous chain tracing. From this study, the binding effectiveness of the gadolinium complexes seems to be related to the nature of the precipitant used for crystallization. These gadolinium complexes represent a new class of high-phasing-power heavy-atom derivatives that may be used for high-throughput structure-determination projects. PMID:12499547

Doping is a threat to sporting excellence.  

PubMed

Savulescu et al have argued that the risk to athletes' welfare provides the only legitimate ground for restricting the use of performance enhancing drugs in sport. In this paper, it is argued that the idea of `sport', properly understood, provides further reason to impose such restrictions. A `balance of excellences' argument is proposed whereby doping is considered objectionable on account of its disrupting the relation between the excellences around which sporting competition is organised. We have reason to restrict the use of performance enhancing drugs in sport not only because of the threat they pose to athletes' health but also because of the threat they pose to athletes' displaying the relevant types of sporting excellence.

Auto Draw from Excel Input Files  

NASA Technical Reports Server (NTRS)

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.

What constitutes an excellent allied health care professional? A multidisciplinary focus group study  

PubMed Central

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.

Tutorial: simulating chromatography with Microsoft Excel Macros.  

PubMed

Chromatography is one of the cornerstones of modern analytical chemistry; developing an instinctive feeling for how chromatography works will be invaluable to future generation of chromatographers. Specialized software programs exist that handle and manipulate chromatographic data; there are also some that simulate chromatograms. However, the algorithm details of such software are not transparent to a beginner. In contrast, how spreadsheet tools like Microsoft Excel™ work is well understood and the software is nearly universally available. We show that the simple repetition of an equilibration process at each plate (a spreadsheet row) followed by discrete movement of the mobile phase down by a row, easily automated by a subroutine (a "Macro" in Excel), readily simulates chromatography. The process is readily understood by a novice. Not only does this permit simulation of isocratic and simple single step gradient elution, linear or multistep gradients are also easily simulated. The versatility of a transparent and easily understandable computational platform further enables the simulation of complex but commonly encountered chromatographic scenarios such as the effects of nonlinear isotherms, active sites, column overloading, on-column analyte degradation, etc. These are not as easily simulated by available software. Views of the separation as it develops on the column and as it is seen by an end-column detector are both available in real time. Excel 2010™ also permits a 16-level (4-bit) color gradation of numerical values in a column/row; this permits visualization of a band migrating down the column, much as Tswett may have originally observed, but in a numerical domain. All parameters of relevance (partition constants, elution conditions, etc.) are readily changed so their effects can be examined. Illustrative Excel spreadsheets are given in the Supporting Information; these are easily modified by the user or the user can write his/her own routine. PMID:23561901

Role modeling excellence in clinical nursing practice.  

PubMed

Role modeling excellence in clinical nursing practice is the focus of this paper. The phenomenological research study reported involved a group of 8 nurses identified by their colleagues as exemplary. The major theme revealed in this study was that these exemplary nurses were also excellent role models in the clinical setting. This paper details approaches used by these nurses that made them excellent role models. Specifically, the themes of attending to the little things, making connections, maintaining a light-hearted attitude, modeling, and affirming others are presented. These themes are discussed within the framework of Watson [Watson, J., 1989. Human caring and suffering: a subjective model for health services. In: Watson, J., Taylor, R. (Eds.), They Shall Not Hurt: Human Suffering and Human Caring. Colorado University, Boulder, CO] "transpersonal caring" and [Bandura, A., 1997. Social Learning Theory. Prentice Hall, Englewood Cliffs, NJ] "Social Learning Theory." Particular emphasis in the discussion is on how positive role modeling by exemplary practitioners can contribute to the education of clinical nurses in the practice setting. PMID:18590978

Modelling of Spiral Coil Heat Exchanger: Model with Easy Simulation Using Ms-Excel  

NASA Astrophysics Data System (ADS)

A theoretical model has been presented for the measurement of heat transfer characteristics of a spiral coil heat exchanger under wet conditions. The solution is obtained using Ms Excel and the simulated results have been compared with the experimental data reported in open literature. It has been found that there is a good agreement between the simulated and experimental values. It is also observed that air mass flow rate and inlet air temperature have significant effect on the increase of the outlet water temperatures. Further outlet air and water temperature decreases with increasing water mass flow rate.

Transportation Safety Excellence in Operations Through Improved Transportation Safety Document  

SciTech Connect

A recent accomplishment of the Idaho National Laboratory (INL) Materials and Fuels Complex (MFC) Nuclear Safety analysis group was to obtain DOE-ID approval for the inter-facility transfer of greater-than-Hazard-Category-3 quantity radioactive/fissionable waste in Department of Transportation (DOT) Type A drums at MFC. This accomplishment supported excellence in operations through safety analysis by better integrating nuclear safety requirements with waste requirements in the Transportation Safety Document (TSD); reducing container and transport costs; and making facility operations more efficient. The MFC TSD governs and controls the inter-facility transfer of greater-than-Hazard-Category-3 radioactive and/or fissionable materials in non-DOT approved containers. Previously, the TSD did not include the capability to transfer payloads of greater-than-Hazard-Category-3 radioactive and/or fissionable materials using DOT Type A drums. Previous practice was to package the waste materials to less-than-Hazard-Category-3 quantities when loading DOT Type A drums for transfer out of facilities to reduce facility waste accumulations. This practice allowed operations to proceed, but resulted in drums being loaded to less than the Waste Isolation Pilot Plant (WIPP) waste acceptance criteria (WAC) waste limits, which was not cost effective or operations friendly. An improved and revised safety analysis was used to gain DOE-ID approval for adding this container configuration to the MFC TSD safety basis. In the process of obtaining approval of the revised safety basis, safety analysis practices were used effectively to directly support excellence in operations. Several factors contributed to the success of MFC’s effort to obtain approval for the use of DOT Type A drums, including two practices that could help in future safety basis changes at other facilities. 1) The process of incorporating the DOT Type A drums into the TSD at MFC helped to better integrate nuclear safety requirements with waste requirements. MFC’s efforts illustrate that utilizing the requirements of other disciplines, beyond nuclear safety, can provide an efficient process. Analyzing current processes to find better ways of meeting the requirements of multiple disciplines within a safety basis can lead to a more cost-effective, streamlined process. 2) Incorporating the DOT Type A drums into the MFC TSD was efficient because safety analysts utilized a transportation plan that provided analysis that could also be used for the change to the TSD addendum. In addition, because the plan they used had already been approved and was in use by the Idaho Cleanup Project (ICP) at the INL, justification for the change to the TSD was more compelling. MFC safety analysts proved that streamlining a process can be made more feasible by drawing from analysis that has already been completed.

Rewarding Excellence and Efficiency in Medicare Payments  

PubMed Central

Medicare could become an innovative leader in using financial incentives to reward health care providers for providing excellent and efficient care throughout a patient's illness. This article examines the variations in cost and quality in the provision of episodes of care and describes how a pay-for-performance payment system could be designed to narrow those variations and serve as a transition to a new Medicare payment policy that would align physicians' incentives with improvements in both quality and efficiency. In particular, Medicare could stimulate greater efficiency by developing new payment methods that are neither pure fee-for-service nor pure capitation, beginning with a pay-for-performance payment system that rewards quality and efficiency and moving to a blended fee-for-service and case-rate system.

Phase transformation temperatures of Zr alloy Excel  

NASA Astrophysics Data System (ADS)

The transformation temperatures of Zr alloy Excel (Zr-3.5%Sn-0.8%Nb-0.8%Mo) pressure tube material were studied using electron microscopy and a quantitative metallography technique. The ?Zr + ?Zr ? ?Zr transus temperature was found to be 968 °C. Also the volume fraction of stabilized ?Zr starts to increase in the temperature range of 600-690 °C. Furthermore, it was observed that ?Zr does not transform to ?'-hcp martensite upon quenching from up to a temperature between 846 °C and 864 °C in the ?Zr + ?Zr region. Instead, the microstructure of ?Zr transforms into a mixture of retained ?Zr with a fine dispersion of athermal ? particles and few ?? orthorhombic martensite laths inside the ?Zr grains. ?Zr was first seen to fully transform to ?'-hcp martensite after quenching from 864 °C; a drastic increase in the volume fraction of ?Zr occurs above this temperature.

2005 College Astronomy Teaching Excellence Workshops  

NASA Astrophysics Data System (ADS)

As part of the education and public outreach efforts of the NASA JPL Navigator and Spitzer EPO Programs along with the American Astronomical Society and the Astronomical Society of the Pacific, astronomy educators affiliated with the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona are conducting a series of two- and three-day teaching excellence workshops for college faculty. These regional workshops are being held at community colleges around the country and in conjunction with professional society meetings, such as the American Astronomical Society and the American Association of Physics Teachers, and through the infrastructure of the National Science Foundation's Summer Chautauqua Workshop program. These interactive teaching excellence workshops focus on dilemmas astronomy teachers face and develop practical solutions for the troubling issues in curriculum, instruction, and assessment. After reviewing the latest research about how students learn, participants define and set measurable student learning goals and objectives for students in their astronomy courses and construct effective course syllabi reflecting the ASTRO 101 goals publicized by the AAS. To improve instruction, participants learn how to create productive learning environments by using interactive lectures, peer instruction, engaging demonstrations, collaborative groups, tutorials, computer-based laboratories, and observational projects. Participants also learn how to write more effective multiple-choice tests and implement authentic assessment strategies including portfolio assessment, performance tasks, and concept maps. Texts used at the workshop include: (i) Learner-Centered Astronomy Teaching, Slater and Adams, Prentice Hall, 2002; (ii) Great Ideas for Teaching Astronomy, Pompea, Brooks Cole, 2000; Insights into the Universe, Slater and Zeilik, and (iv) Lecture-Tutorials for Introductory Astronomy, Adams, Prather, & Slater, Prentice Hall, 2005.

The long wait for medical excellence.  

PubMed

In October 1997 the book Demanding Medical Excellence: Doctors and Accountability in the Information Age provided a pathbreaking examination of the quality of American health care. It documented rampant medical error and the absence of evidence-based practice, highlighted the potential of electronic health records (EHRs), endorsed what is now known as value purchasing, and showed how patients could exert more control over their care. Although the book suggested that transformational change was imminent, sixteen years later little has changed in some areas (medical error), while in others (evidence-based medicine and population health) change is only now gaining momentum. The exception is technology, where incentives boosted EHR use and the Internet has made a vast array of information available to patients. Paradigm shifts are traumatic, and only recently has intense financial pressure made greater clinical accountability seem less painful than retaining the tradition of untrammeled autonomy. In hearing rooms and hospital hallways, the policy conversation is changing. This shift, though an unavoidable source of anxiety, nonetheless promises a genuine renewal of American medicine.

Who doesn't deserve excellent care?  

PubMed

Discussion on implementation of the Excellent Care for all Act, 2010 (ECFA Act), Bill 46, has focused on the hospital sector in Ontario, but it also has relevance outside the hospital setting. As primary healthcare, long-term care and home care all receive public funding, these sectors should be expected to be compliant with Bill 46. But does the act also govern government-funded (i.e., by other than the Ministry of Health and Long-Term Care) community-based programs such as adult day programs, meals-on-wheels, nutrition programs for children, and more? We propose that we cannot exclude any of these essential programs. We also consider the non-hospital sector and health organizations that do not receive public funding. The healthcare system will be well served if we consider whether the EFCA Act's key elements should be implemented across the system both vertically and horizontally. Vertical implementation in the hospital sector could be followed by primary care, home and community care, long-term care, and the rest of the vertical silos within the healthcare system. But by taking the horizontal approach, all sectors within and outside of what we traditionally think of health would be integrated using an evidence-informed and outcome-based approach and methodology.

Beyond accreditation: excellence in medical education.  

PubMed

Medical school accreditation is a relatively new phenomenon in Korea. The development of an accreditation body and standards for a two-tiered "Must" and "Should" system in 1997 eventually led to the implementation of a third "Excellence" level of attainment. These standards were conceived out of a desire to be able to first recognize and promote outstanding performance of medical schools, second to provide role models in medical education, and furthermore to preview the third level as potential components of the pre-existing second level for the next accreditation cycle. It is a quality-assurance mechanism that, while not required for accreditation itself, pushes medical schools to go beyond the traditional requirements of mere pass-or-fail accreditation adequacy, and encourages schools to deliver an unprecedented level of medical education. The Association for Medical Education in Europe developed its own third-tier system of evaluation under the ASPIRE project, with many similar goals. Due to its advanced nature and global scope, the Korean accreditation body has decided to implement the ASPIRE system in Korea as well. PMID:24050749

ESD training: A challenging path to excellence  

PubMed Central

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.

Nonlinear least-squares data fitting in Excel spreadsheets.  

PubMed

We describe an intuitive and rapid procedure for analyzing experimental data by nonlinear least-squares fitting (NLSF) in the most widely used spreadsheet program. Experimental data in x/y form and data calculated from a regression equation are inputted and plotted in a Microsoft Excel worksheet, and the sum of squared residuals is computed and minimized using the Solver add-in to obtain the set of parameter values that best describes the experimental data. The confidence of best-fit values is then visualized and assessed in a generally applicable and easily comprehensible way. Every user familiar with the most basic functions of Excel will be able to implement this protocol, without previous experience in data fitting or programming and without additional costs for specialist software. The application of this tool is exemplified using the well-known Michaelis-Menten equation characterizing simple enzyme kinetics. Only slight modifications are required to adapt the protocol to virtually any other kind of dataset or regression equation. The entire protocol takes approximately 1 h. PMID:20134427

Integration of production analyst and Microsoft Excel`s Solver for production forecasts and optimization  

SciTech Connect

Mobil North Sea Ltd. has used OGCI`s Production Analyst (PA) for several years for reservoir management and surveillance. Once most professionals had been migrated to Microsoft Windows and Excel, the authors began to integrate the spread sheet with PA for specialized applications. Production optimization and forecasts are two applications of significant economic benefit. They developed an Excel spreadsheet and macro that use the Solver and production-decline data from PA for predicting the maximum platform oil production while honoring gas-compression and water-handling constraints. By use of PA, a database of decline-curve information is generated by well for the relationships of oil rate, GOR, and water cut to cumulative oil. Other input required for the forecast are the combination of months and years to forecast, gas compression limit, water-handling limit, and platform efficiency at each timestep. This model adds value to their operations by leveraging existing products and data to predict facility-constrained production schedules. A custom program with this type of functionality would certainly be more expensive than the combined costs of PA and Excel. The integration of these tools provides cost-effective solutions to the specialized problems experienced in oil and gas exploitation.

Highlights: Black-Right-Pointing-Pointer Methyl blue (MB) stacks onto the plane of reduced graphene oxide (rGO) by strong {pi}-{pi} interactions. Black-Right-Pointing-Pointer Sulfo groups of MB prevent rGO from aggregating by electrostatic and steric repulsions. Black-Right-Pointing-Pointer MB-functionalized rGO (MB-rGO) shows excellent solubility and stability in aqueous solution. Black-Right-Pointing-Pointer Electrical conductivity of MB-rGO is almost two orders of magnitude larger than that of GO. -- Abstract: {pi} stacking and water-solubility of methyl blue (MB) are expected to facilitate the hydrazine mediated reduction of graphene oxide (GO) in aqueous environment. Our newly obtained MB-functionalized reduced graphene oxide (MB-rGO) exhibited excellent solubility and stability in water. The results showed that the MB molecules stacked non-covalently onto the basal plane of rGO while the sulfo groups of MB prevented the rGO from aggregation. In addition, the better electrical conductivity of MB-rGO than that of GO was analyzed. This novel conductive MB-rGO should have promising applications in diverse nanotechnological areas, such as electronic and optoelectronic devices, photovoltaics, sensors, and microfabrication.

High-resolution melting (HRM) analysis is a recently developed molecular technique proved to be applicable for detection of genetic variation, notably in sudden cardiac death. In certain circumstances, especially in postmortem genetic investigations, the formalin-fixed and paraffin-embedded (FFPE) tissues are the only DNA source available. The present study aimed to develop HRM assays, optimized for the analysis of FFPE tissues, to detect sequence variations in KCNQ1 exons in a prospective population-based series of postmortem negative sudden death and to compare the results between the paired freshly frozen and FFPE tissue samples simultaneously obtained from the same case. The analyses were conducted in each case of sudden death involving cases younger than 35 years with no significant morphological anomalies particularly with no cardiac structural disease and with negatives toxicological investigations. HRM analysis was successfully optimized for 13 of the 16 exons of the KCNQ1 gene. All mutated samples were correctly identified by HRM whatever the type of tissue tested. However, for FFPE samples, HRM indicated more positive samples than classical sequencing, used in parallel, due to the degradation of DNA by formalin fixation. This is the first postmortem study of KCNQ1 mutation detection with HRM on DNA extracted from FFPE samples with adapted protocol. Despite the false-positive detection, we concluded that the use of HRM as a screening method with FFPE samples to analyze KCNQ1 mutations can reduce the number of sequencing reactions and, thus, results in substantial time and cost savings.

Sex Differences and Science: The Etiology of Science Excellence  

PubMed Central

Background Are there sex differences in the etiology of high performance in science in childhood that could contribute to the under-representation of women in scientific careers? In this study the relative contributions of genetic and environmental influences on high performance in science in both boys and girls were assessed using standard twin analyses. Methods The sample included 3000 twin pairs from the UK Twins Early Development Study (TEDS). Science performance ratings based on the UK National Curriculum were collected from teachers when the twins were 9, 10 and 12 years old. Science excellence was defined as performing above the 85th percentile. Sex-limitation liability threshold models were used to assess sex differences in etiology. Results We found no evidence for quantitative or qualitative sex differences in the etiology of science excellence, which was moderately heritable (30–50%), and influenced by both shared (40–56%) and non-shared (10–13%) environmental influences. Conclusions Although boys and girls do not differ genetically in relation to school science performance per se, the under-representation of women in scientific careers may be due to attitudes rather than aptitudes.

Controllable synthesis Co3O4 nanorods and nanobelts and their excellent lithium storage performance  

NASA Astrophysics Data System (ADS)

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.

Excellently guarded materials against UV and oxygen in the surfactant molecular complex crystal matrix  

NASA Astrophysics Data System (ADS)

Crystalline surfactant molecular complexes (SCMs) generated between quaternary ammonium cationic surfactants such as CTAB and various additives disclose their excellent protective properties from UV light and oxygen to complex additive materials, which are occluded in the complex crystal matrix. The effects of UV and oxygen were followed by the absorption decay of additive chromophores in comparing that of naked additive specimens with that of those in the complexed state. From the decay profiles, the rate constants and the half-life times were estimated under the assumptions in which the photo and oxidation processes were dominated in accordance with the first-ordered reaction. The results afford us promising prospects in extending the shelf-life of every material, above all medicinal drug, with the consequence that these obtained values evidently demonstrate the remarkably suppressed rate and extremely elongated half-life times.

Synthesis, characterization and excellent photocatalytic activity of Ag/AgBr/MoO3 composite photocatalyst  

NASA Astrophysics Data System (ADS)

A novel composite photocatalyst Ag/AgBr/MoO3 was successfully synthesized via a simple precipitation method at room temperature. The obtained products were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, high-resolution transmission electron microscopy and UV-vis diffuse reflectance spectroscopy in detail. The photocatalytic activity of the samples was evaluated by monitoring the degradation of rhodamine B (RhB) solution under visible-light irradiation. The results showed that the photocatalytic activity of Ag/AgBr/MoO3 composite significantly enhanced and the degradation ratio of RhB reached 97.7 % after 15 min only. The excellent photocatalytic activity might be closely related to the large surface area, porosity structure and efficient separation of photoinduced electron-hole pairs. The possible reaction mechanism was also discussed.

The Preparation of Microzonation Map of the Gulf of Buyukcekmece using results obtain by Vertical Electrical Sounding Measurements with Multi-Channel Analysis of Surface Wave and Microtremor Array Method  

NASA Astrophysics Data System (ADS)

Istanbul is a megacity with 17 million inhabitants. After the 17 August 1999 earthquake, many researchers have focused on the mitigation of earthquake hazards in the Sea of Marmara and its vicinity. If we want to lessen the effects of such an earthquake, we have to learn about three different types of problems which are properties of the earthquake's source, whether of site effect or properties of engineering structures. When ?stanbul Metropolitian Municipilaty obtained a World Bank Credit 5 years ago, they had a microzonation report for only a limited area which finished at Har amidere in the western site of Istanbul. Because they will not have any new project, the western side of Haramidere hasn't been studied by any scientist. For this reason, we focused on the Gulf of Buyukcekmece which is located on the western part of Haramidere and suffered in the 1999 earthquake. There are five geological units in the study area such as Bakirkoy formation, Gurpinar formation, Çukurçe?me formation, Güngören formation and Alluvial deposit. We conducted some measurements which are multi-channel analysis of surface wave (MASW), microtremor array method (MAM) and vertical electrical sounding(VES). The aim of using VES data is to determine bedrock depth, learn whether there is a new fault and learn the electrical properties of each layer of bedrock. The MASW method is so attactive, cheap and fast. According to seismic refraction, it has some advantages that are determining the deeper part of sub-surface, lower velocity layers and velocity contrast. Especially, we use natural sources; MAM methods are more useful method in the city. For all of these purposes, we collected MASW and MAM measurements at 80 sites and VES measurements at 20 sites. As primary results for VES measurements, we determined the bedrock depth by evaluating the VES measurements for the central, eastern and western part of Buyukcekmece Gulf. Bedrock depth is 308 meters in the central and eastern part of the Gulf and it reaches up to 448 meter in the north-eastern part. Its value obtained 471 meters in the western part of the Gulf. The depth of bedrock is determined as approximately the same on both sides of the Gulf. We collected only one VES measurement in the central part of the Gulf where the Buyukcekmece lake meets the Sea of Marmara. The bedrock depth is determined as 52 meters at this point. As primary results for MASW-MAM measurements, we determined Vs30 as average 311 m/s. Due to the frequency range being different for MASW and MAM measurements, wavelength is also different. For this reason, we evaluated both measurements together. Shear wave velocity is greater than the other parts in the study area. Especially, the north-west side (District of Tepecik) of the Gulf is the maximum value. The central part of the Gulf close to the Sea of Marmara decreases to Vs30 value.

Sunscreens: obtaining adequate photoprotection.  

PubMed

Adequate photoprotection plays a paramount role in reducing the burden of both photoaging and photocarcinogenesis. The scope of photoprotective strategies employed by the public, from most to least effective, includes: sun avoidance, seeking shade, the use of protective clothing, and the application of sunscreen. Among these options, sunscreen use remains the strategy most frequently employed by the public--a reversal of the preferred order of photoprotection. Given this trend, it is clear why sunscreens invariably take center stage in any discussion regarding obtaining adequate photoprotection. PMID:22913442

A comparative study of results obtained in magnetotelluric deep soundings in Villarrica active volcano zone (Chile) with gravity investigations, distribution of earthquake foci, heat flow empirical relationships, isotopic geochemistry 87Sr/ 86Sr and SB systematics  

NASA Astrophysics Data System (ADS)

The first magnetotelluric deep soundings in Chile were carried out during 1986 in the Villarrica active volcano zone (39°25'S, 71°57'W). In the TM mode of polarization, the curves show a distorted segment with dispersion. A static distortion at long periods is observed in curves in the TE mode of polarization; the segment was shifted vertically to fit the geomagnetic global model values at daily periods. This modified curve was used for 1D modelling to determine the electrical structure in the study area. The upper level of the intermediate conducting layer of resistivity 20-60 ? m is found to be at 35-50 km depth. A higher resistivity layer (600 ? m), starting at 100 km depth, may be resolved in the intermediate conducting layer. A sharp decrease in the resistivity is shown by the model at 500 km. Large heterogeneities at the level of the conducting layer encountered in the 1D modelling, and increased resistivity of the ultimate layer, may account for distortion observed at long periods. Two-dimensional test models show that the conducting layer in the area of Villarrica volcano may be an anomalous heated layer surrounded by rocks of higher resistivity of about 2 × 10 3 ? m. These features correspond to the interaction with a subsiding oceanic lithosphere resulting in a complex thermal structure and perturbed resistivity distribution in transition zones of the Pacific type such as Chile, and to the existence of a megafault and a system of fractures in the sounding area. These facts make it difficult to determine the conductance of the electrical asthenosphere. The parameters of the model structure correlate well with geophysical and geochemical results obtained in the area by other workers. Gravity studies indicate a maximum crustal thickness of about 37 km, which implies a non-full compensation according to the Airy hypothesis. The morphology of the Wadati-Benioff zone clearly shows a sharp decrease of earthquake foci at 50 km depth, and a reinitiation of seismic activity from a depth of 100 km down to 160 km. Kaufman and Keller and Levi and Lysak empirical relationships between heat flow and thickness of the lithosphere are somewhat consistent when the parameters of the model structure are assumed. The strontium isotope ratios are indicative of minimal crustal contamination of mantle-derived magmas, thus allowing a relatively thin crust under the area. Furthermore, the SB index of partial melting of mantle peridotite may suggest the contribution of uprising material from the deep asthenosphere through fractures extending to depth.

Best practices: applying management analysis of excellence to immunization.  

PubMed

The authors applied business management tools to analyze and promote excellence and to evaluate differences between average and above-average immunization peformers in private practices. The authors conducted a pilot study of 10 private practices in Pennsylvania using tools common in management to assess practices' organizational climate and managerial style. Authoritative and coaching styles of physician leaders were common to both groups. Managerial styles that emphasized higher levels of clarity and responsibility managerial styles were evident in the large practices; and rewards and flexibility styles were higher in the small above-average practices. The findings of this pilot study match results seen in high performers in other industries. It concludes that the authoritative style appears to have the most impact on performance. It has interesting implications for training/behavior change to improve immunization rates, along with traditional medical interventions. PMID:15921143

Excellent microwave absorption property of Graphene-coated Fe nanocomposites  

PubMed Central

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.

A biodegradable shape-memory nanocomposite with excellent magnetism sensitivity.  

PubMed

This paper reports a kind of biodegradable nanocomposite which can show an excellent shape-memory property in hot water or in an alternating magnetic field with f = 20 kH and H = 6.8 kA m(-1). The nanocomposite is composed of crosslinked poly(epsilon-caprolactone) (c-PCL) and Fe(3)O(4) nanoparticles. The crosslinking reaction in PCL with linear molecular structure was realized using benzoyl peroxide (BPO) as an initiator. The biocompatible Fe(3)O(4) magnetite nanoparticles with an average size of 10 nm were synthesized according to a chemical coprecipitation method. The initial results from c-PCL showed crosslinking modification had brought about a large enhancement in shape-memory effect for PCL. Then a series of composites made of Fe(3)O(4) nanoparticles and c-PCL were prepared and their morphological properties, mechanical properties, thermodynamic properties and shape-memory effect were investigated in succession. Significantly, the photos of the shape-memory process confirmed the anticipatory magnetically responsive shape-recovery effect of the nanocomposites because inductive heat from Fe(3)O(4) can be utilized to actuate the c-PCL vivification from their frozen temporary shape. All the results imply a very feasible method to fabricate shape-memory PCL-based nanocomposites since just a simple modification is required. Additionally, this modification would endow an excellent shape-memory effect to all other kinds of polymers so that they could broadly serve in various fields, especially in medicine. PMID:19451683

Synthesis of DIBAC analogues with excellent SPAAC rate constants.  

PubMed

In search for increased reactivity in strain-promoted azide alkyne cycloadditions (SPAAC), the synthesis of new and more reactive cyclooctynes is of pivotal importance. To identify cyclooctynes with enhanced reactivity, without loss of stability, the synthesis and kinetic analysis of new dibenzoazacyclooctyne (DIBAC) analogues were conducted. Starting from iodobenzyl alcohol analogues and ortho-ethynylaniline various substituted dihydrodibenzo[b,f]azocines were produced. Subsequent bromination and elimination proved to be difficult depending on the aromatic substitution pattern, yielding chloro-, bromo-, and methoxy-substituted DIBACs in moderate yield. In the elimination reaction towards nitro- and Br,Cl-DIBAC, the corresponding cyclooctene was obtained instead of the cyclooctyne. Additionally, a dimethoxy-substituted DIBAC analogue was prepared following an alternative route involving light-induced deprotection of a cyclopropenone derivative. In total, four DIBAC analogues were successfully prepared showing excellent rate constants in the SPAAC reaction ranging from 0.45 to 0.9 M(-1) s(-1), which makes them comparable to the fastest cyclooctynes currently known.

Withdrawal time in excellent or very poor bowel preparation qualities  

PubMed Central

AIM: To evaluate association(s) between withdrawal time and polyp detection in various bowel preparation qualities. METHODS: Retrospective cohort analysis of screening colonoscopies performed between January 2005 and June 2011 for patients with average risk of colorectal cancer. Exclusion criteria included patients with a personal history of adenomatous polyps or colon cancer, prior colonic resection, significant family history of colorectal cancer, screening colonoscopy after other abnormal screening tests such as flexible sigmoidoscopy or barium enema, and screening colonoscopies during in-patient care. All procedures were performed or directly supervised by gastroenterologists. Main measurements were number of colonic segments with polyps and total number of colonic polyps. RESULTS: Multivariate analysis of 8331 colonoscopies showed longer withdrawal time was associated with more colonic segments with polyps in good (adjusted OR = 1.16; 95%CI: 1.13-1.19), fair (OR = 1.13; 95%CI: 1.10-1.17), and poor (OR = 1.18; 95%CI: 1.11-1.26) bowel preparation qualities. A higher number of total polyps was associated with longer withdrawal time in good (OR = 1.15; 95%CI: 1.13-1.18), fair (OR = 1.13; 95%CI: 1.10-1.16), and poor (OR = 1.20; 95%CI: 1.13-1.29) bowel preparation qualities. Longer withdrawal time was not associated with more colonic segments with polyps or greater number of colonic polyps in bowel preparations with excellent (OR = 1.07, 95%CI: 0.99-1.26; OR = 1.11, 95%CI: 0.99-1.24, respectively) and very poor (OR = 1.02, 95%CI: 0.99-1.12; OR = 1.05, 95%CI: 0.99-1.10, respectively) qualities. CONCLUSION: Longer withdrawal time is not associated with higher polyp number detected in colonoscopies with excellent or very poor bowel preparation quality.

The test model was the 0.0175-scale thin skin thermocouple model (60-OTS) of the Rockwell International vehicle 5 configuration. The test was conducted at nominal Mach numbers of 2.5, 3.5, 4.5, and 5.5, and a free stream unit Reynolds number of 5 million per ft. Heat transfer data were obtained for angles of attack of 0, + or - 5, and 10 deg and yaw angles of 0, 3, and 6 deg. The integrated vehicle model was tested with the external tank configured with both a smooth ogive nose and an ogive nose with a spherical nose tip (nipple nose). The remainder of the test was conducted with the external tank installed alone in the tunnel.

Antihyperglycaemic effect of 'Ilogen-Excel', an ayurvedic herbal formulation in streptozotocin-induced diabetes mellitus.  

PubMed

'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

Pathways to Excellence Scholarship Program for women in STEM fields  

NASA Astrophysics Data System (ADS)

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.

The OMAHA System was adopted as the documentation system in an interventional study. To systematically record client care and facilitate data analysis, two Office Excel files were developed. The first Excel file (File A) was designed to record problems, care procedure, and outcomes for individual clients according to the OMAHA System. It was used by the intervention nurses in the study. The second Excel file (File B) was the summary of all clients that had been automatically extracted from File A. Data in File B can be analyzed directly in Excel or imported in PASW for further analysis. Both files have four parts to record basic information and the three parts of the OMAHA System. The computerized OMAHA System simplified the documentation procedure and facilitated the management and analysis of data. PMID:24943560

Torsional Angle Driver (TorAD) System for HyperChem/Excel  

NASA Astrophysics Data System (ADS)

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.

Do mental skills make champions? Examining the discriminant function of the psychological characteristics of developing excellence questionnaire.  

PubMed

The ability to successfully develop to the highest levels in sport is dependent on a range of variables, not least an individual's ability to cope with the various challenges of development. Psychological Characteristics of Developing Excellence (PCDEs) include both the trait characteristics and the state-deployed skills that have been shown to play a crucial role in the realisation of potential. Psychological characteristics of developing excellence equip aspiring elites with the mental skills, attitudes, and emotions to cope with the challenges of the development pathway, as well as underpinning their capacity to make the most of their innate abilities. The Psychological Characteristics of Developing Excellence Questionnaire (PCDEQ) was designed to assess the possession and deployment of these characteristics. The purpose of this paper was to examine the ability of the Psychological Characteristics of Developing Excellence Questionnaire to effectively discriminate between good and poor developers based on their current possession and deployment of psychological characteristics of developing excellence. Two hundred and eighty-five athletes (n = 192 team athletes; n = 93 individual athletes) completed the Psychological Characteristics of Developing Excellence Questionnaire. Results from the discriminant function analysis suggest that the Psychological Characteristics of Developing Excellence Questionnaire correctly classifies between 67% and 75% of athletes based on their responses. The Psychological Characteristics of Developing Excellence Questionnaire can be used as a formative assessment tool to direct training programmes by identifying weaknesses in psychological characteristics of developing excellence and incorporating specific training to address these weaknesses in advance of developmental challenges.

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.  

PubMed

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

10(-7) contrast ratio at 4.5lambda/D: New results obtained in laboratory experiments using nano-fabricated coronagraph and multi-Gaussian shaped pupil masks.  

PubMed

We present here new experimental results on high contrast imaging of 10-7 at 4.lambda/D (lambda=0.820 microns) by combining a circular focal plane mask (coronagraph) of 2.5lambda/D diameter and a multi-Gaussian pupil plane mask. Both the masks were fabricated on very high surface quality (lambda/30) BK7 optical substrates using nano-fabrication techniques of photolithography and metal lift-off. This process ensured that the shaped masks have a useable edge roughness better than lambda/4 (rms error better than 0.2 microns), a specification that is necessary to realize the predicted theoretical limits of any mask design. Though a theoretical model predicts a contrast level of 10-12, the background noise of the observed images was speckle dominated which reduced the contrast level to 4x10-7 at 4.5lambda/D. The optical setup was built on the University of Illinois Seeing Improvement System (UnISIS) optics table which is at the Coude focus of the 2.5-m telescope of the Mt. Wilson Observatory. We used a 0.820 micron laser source coupled with a 5 micron single-mode fiber to simulate an artificial star on the optical test bench of UnISIS. PMID:19495130

The first results obtained with the installation HORIZON-T  

NASA Astrophysics Data System (ADS)

A new installation HORIZON-T is commissioned at the high altitude scientific station of P.N. Lebedev Institute at the Tien-Shan Mountains. The purpose of this installation is to study EAS arriving at the zenith angles close to the horizon. The installation consists of three Vavilov - Cherenkov detectors located at the center of the installation and five registration points for muons which are placed within 500 m from the center. With the help of HORIZON-T installation EAS events have been detected at zenith angles more than 65 degrees, some of which had muon pulses with the front being ahead of one from Vavilov - Cherenkov pulses by more than 20 ns. Simulations show that such EAS are most likely initiated by primary nuclei with the mass more than 10.

NetpathXL - An Excel Interface to the Program NETPATH  

USGS Publications Warehouse

NetpathXL is a revised version of NETPATH that runs under Windows? operating systems. NETPATH is a computer program that uses inverse geochemical modeling techniques to calculate net geochemical reactions that can account for changes in water composition between initial and final evolutionary waters in hydrologic systems. The inverse models also can account for the isotopic composition of waters and can be used to estimate radiocarbon ages of dissolved carbon in ground water. NETPATH relies on an auxiliary, database program, DB, to enter the chemical analyses and to perform speciation calculations that define total concentrations of elements, charge balance, and redox state of aqueous solutions that are then used in inverse modeling. Instead of DB, NetpathXL relies on Microsoft Excel? to enter the chemical analyses. The speciation calculation formerly included in DB is implemented within the program NetpathXL. A program DBXL can be used to translate files from the old DB format (.lon files) to NetpathXL spreadsheets, or to create new NetpathXL spreadsheets. Once users have a NetpathXL spreadsheet with the proper format, new spreadsheets can be generated by copying or saving NetpathXL spreadsheets. In addition, DBXL can convert NetpathXL spreadsheets to PHREEQC input files. New capabilities in PHREEQC (version 2.15) allow solution compositions to be written to a .lon file, and inverse models developed in PHREEQC to be written as NetpathXL .pat and model files. NetpathXL can open NetpathXL spreadsheets, NETPATH-format path files (.pat files), and NetpathXL-format path files (.pat files). Once the speciation calculations have been performed on a spreadsheet file or a .pat file has been opened, the NetpathXL calculation engine is identical to the original NETPATH. Development of models and viewing results in NetpathXL rely on keyboard entry as in NETPATH.

Everyday Excellence: A Framework for Professional Nursing Practice in Long-Term Care  

PubMed Central

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.

The Relationship of Learning Motivation, Achievement and Satisfaction for Nurses Learning Simple Excel VBA Information Systems Programming.  

PubMed

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

A new method for obtaining transparent electrodes.  

PubMed

In this article, we propose a simple scheme to make a metallic film on a semi-infinite substrate optically transparent, thus obtaining a completely transparent electrode in a desired frequency range. By placing a composite layer consisting of dielectric and metallic stripes on top of the metallic one, we found that the back-scattering from the metallic film can be almost perfectly canceled by the composite layer under certain conditions, leading to transparency of the whole structure. We performed proof-of-concept experiments in the terahertz domain to verify our theoretical predictions, using carefully designed metamaterials to mimic plasmonic metals in optical regime. Experiments are in excellent agreement with full-wave simulations. PMID:23037428

EDITORIAL: Excelling under strain: band engineering in nanomaterials Excelling under strain: band engineering in nanomaterials  

NASA Astrophysics Data System (ADS)

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

Irradiation induced microstructural changes in Zr-Excel alloy  

NASA Astrophysics Data System (ADS)

The in situ ion irradiation technique has been employed to elucidate irradiation damage in the dual phase Zr-Excel alloy. 1 MeV Kr ion irradiation experiments were conducted at different temperatures ranging from 100 °C to 400 °C. Damage microstructures have been characterized by transmission electron microscopy in both the alpha (?) and beta (?) phases after a maximum dose of 10 dpa at different temperatures. Several important observations including low temperature -component loop formation, and irradiation induced omega (?) phase precipitation have been reported. In situ irradiation provided an opportunity to observe the nucleation and growth of basal plane -component loops and irradiation induced dissolution of secondary phase precipitates at the same time. It has been shown that under Kr ion irradiation the -component loops start to nucleate and grow above a threshold dose, as has been observed for neutron irradiation. Furthermore, the role of temperature, material composition and pre-irradiation microstructure has been discussed in detail. lt;c>-Component loops nucleate and grow above a threshold dose which has been recorded as 2.5 dpa at 400 °C. These loops nucleate in the proximity of secondary phase precipitates and grow as the precipitates shrink due to irradiation induced dissolution. The size of -component loops increases, whereas defect number density decreases with an increase of irradiation temperature. There is a significant difference of the -component loops microstructure in the as-received and heat-treated materials. -component loops seem to be of much larger size in AR material and the density of these loops drops significantly compared to the HT material. Semi-denuded zones are formed at the grain boundaries of the ?-phase, which is attributed to the depletion of Fe on the grain boundary. omega;-Phase precipitation and growth happens at all irradiation temperatures. Aging experiments on unirradiated specimens confirm that at higher temperature there are combined effects from radiation damage and isothermal nucleation; whereas at lower temperature only radiation induced ?-phase formation occurs in the time scales studied. The volume fraction of ?-phase decreases with an increase of irradiation temperature and the precipitate size increases with an increase of irradiation temperature, however in unirradiated material both volume fraction and precipitate size increase with an increase in temperature. This study can be implicated to improve the design of generation IV CANDU-SCWR. Low temperature formation of -component loops and ?-phase precipitation are striking results signifying potential irradiation growth and resultant changes in the mechanical properties of CANDU-SCWR fuel channel designs.

Deposition temperature independent excellent passivation of highly boron doped silicon emitters by thermal atomic layer deposited Al2O3  

NASA Astrophysics Data System (ADS)

In this work, we demonstrate that by using H2O based thermal atomic layer deposited (ALD) Al2O3 films, excellent passivation (emitter saturation current density of ~28 fA/cm2) on industrial highly boron p+-doped silicon emitters (sheet resistance of ~62 ?/sq) can be achieved. The surface passivation of the Al2O3 film is activated by a fast industrial high-temperature firing step identical to the one used for screen printed contact formation. Deposition temperatures in the range of 100-300 °C and peak firing temperatures of ~800 °C (set temperature) are investigated, using commercial-grade 5'' Cz silicon wafers (~5 ? cm n-type). It is found that the level of surface passivation after activation is excellent for the whole investigated deposition temperature range. These results are explained by advanced computer simulations indicating that the obtained emitter saturation current densities are quite close to their intrinsic limit value where the emitter saturation current is solely ruled by Auger recombination. The process developed is industrially relevant and robust.

Encapsulating Pd Nanoparticles in Double-Shelled Graphene@Carbon Hollow Spheres for Excellent Chemical Catalytic Property  

PubMed Central

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.

Excellent magnetic properties of fullerene encapsulated ferromagnetic nanoclusters  

NASA Astrophysics Data System (ADS)

Ferromagnetic nanoclusters are very useful for a magnetic recording. However, application of ferromagnetic nanoclusters is limited due to air-oxidation. One way to solve air-oxidation is to encapsulate ferromagnetic nanoclusters with inert materials such as carbon when they are produced. This allows us to keep excellent magnetic properties for a long time. In this work, we report a very simple synthetic method of fullerene (i.e., onions and nanotubes) encapsulated ferromagnetic nickel and cobalt nanoclusters by thermally decomposing metallocene vapors with a resistive heater. Protection from air-oxidation was tested by annealing encapsulated ferromagnetic nanoclusters in air up to ˜180°C for half a day and then, recording XRD patterns. No oxide peaks were observed in the XRD patterns, indicating that oxidation protection via fullerene encapsulation is very good. Magnetic property measurement showed that both fullerene encapsulated nickel and cobalt nanoclusters possessed excellent magnetic properties.

Excel Heat Transfer Add-in for Engineering Courses  

NSDL National Science Digital Library

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.

Tapping into water: key considerations for achieving excellence in school drinking water access.  

PubMed

Objectives. We examined free drinking water access in schools. Methods. We conducted cross-sectional interviews with administrators from 240 California public schools from May to November 2011 to examine the proportion of schools that met excellent water access criteria (i.e., location, density, type, maintenance, and appeal of water sources), school-level characteristics associated with excellent water access, and barriers to improvements.

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

NASA Astrophysics Data System (ADS)

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.

Acoustic barriers obtained from industrial wastes.  

PubMed

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

An Excel Workbook for Identifying Redox Processes in Ground Water  

USGS Publications Warehouse

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.

Nanoalumina obtained by pyrosol method  

NASA Astrophysics Data System (ADS)

Ceramic materials are interesting due to their properties such as chemical and thermal stability, corrosion resistance, biocompatibility, piezoelectricity, high dielectricity. Also, nano-sized materials may have properties different from the micro scale materials. Pyrosol method is an alternative method to obtain nanoscale particles. In this study alumina particles were prepared by pyrosol method using AlCl3 (0.1 M and 0.05 M) as precursor solutions. The particles were obtained by maintaining the temperature of 400 °C in the pyrolysis furnace. Then, the powders were heat treated at 1000 °C for 2 hours. The X-ray diffraction analyses indicated that the obtained nanoparticles were identified as a mixture of a and g crystalline alumina. Scanning electron microscopy images showed that the prepared Al2O3 nanoparticles obtained from the concentration of 0.05 M had smaller dimensions than those obtained from the concentration of 0.1 M. Images of transmission electron microscopy showed spherical particles with the median diameter approximately of 150 nm, using as precursor AlCl3 solution (0.05 M).

Using Imported Data In EXCEL: Plot Atmospheric Temperature  

NSDL National Science Digital Library

This activity demonstrates how to import data from the Internet and make EXCEL graphs. The instructions included were provided by a classroom teacher who used these instructions with high school students. Following detailed, illustrated instructions, students will complete the activity by working with data from two cities: Little Rock, Arkansas and Miami, Florida. Since temperature generally decreases with height, this change is called the lapse rate. The average global lapse rate is about 0.6°C per 100 meters. However, lapse rates vary due to location and time. The data from this activity shows different lapse rates in two cities, with a cold front separating the cities; one of the cities is influenced by a polar air mass, while the other is affected by a tropical air mass.

Achieving quality excellence at the Diablo Canyon Nuclear Power Plant  

SciTech Connect

Quality assurance methods at the Diablo Canyon plant were transformed from the then typical industry practices that often alienated professional and technical people, as well as craftsmen and their foremen, to a cooperative method that allowed plant personnel to work together as a team. It has created an attitude to do it right the first time. The roles of quality professionals were expanded to include teaching and coaching to facilitate enhanced communication between and within functional organizations. This included regular presentations to managers and line personnel in an informal group participative atmosphere. These presentations have become widely known at the plant as quality awareness tailboard sessions. These presentations are intended to increase personnel sensitivity to the subject of quality and quality management. Economic achievement of excellence in quality is essential to remain competitive in today's marketplace. The proactive team-oriented approach of quality assurance achieves the bottom line of high quality with concurrently enhanced productivity and cost-effectiveness.

Optimizing outcomes with azacitidine: recommendations from Canadian centres of excellence  

PubMed Central

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.

A superhydrophobic sponge with excellent absorbency and flame retardancy.  

PubMed

Frequent oil spillages and the industrial discharge of organic solvents have not only caused severe environmental and ecological damage, but also create a risk of fire and explosion. Therefore, it is imperative, but also challenging, to find high-performance absorbent materials that are both effective and less flammable. Here we present a superior superhydrophobic sponge that exhibits excellent absorption performance through a combination of its superhydrophobicity, high porosity, and robust stability. More importantly, it inherits the intrinsic flame-retardant nature of the raw melamine sponge, and is thus expected to reduce the risk of fire and explosion when being used as an absorbent for flammable oils and organic compounds. Moreover, the fabrication of this sponge is easy to scale up, since it does not use a complicated process or sophisticated equipment. These characteristics make the sponge a much more competitive product than the commercial absorbent, nonwoven polypropylene fabric. PMID:24711147

Demagnetization Analysis in Excel (DAIE) - An open source workbook in Excel for viewing and analyzing demagnetization data from paleomagnetic discrete samples and u-channels  

NASA Astrophysics Data System (ADS)

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).

Optimal spectra of the phosphor-coated white LEDs with excellent color rendering property and high luminous efficacy of radiation.  

PubMed

A model for spectra of the phosphor-coated white LED (p-W LED) with a blue chip, a red chip, and green and yellow phosphors is presented. The optimal spectra of p-W LEDs with correlated color temperatures (CCTs) of 2700-6500 K have been obtained with a nonlinear program for maximizing luminous efficacy of radiation (LER) under conditions of both color-rendering indices (CRIs) and special CRIs of R9 strong red above 98. The simulation results show that p-W LEDs with one InGaN blue (450 nm) chip, one AlGaInP red (634 nm) chip, and green (507 nm) and yellow (580 nm) silicate phosphors can realize white lights with CRIs of about 98 and special CRIs of R9 for strong red above 98. The average of the special CRIs R9 to R12 for the four saturated colors (red, yellow, green, and blue) is above 95. R13 for the skin of women's faces at about 100, as well as LERs above 296 lm/W at CCTs of 2700-6500 K. LERs of excellent CRI p-W LEDs with one InGaN blue chip, one AlGaInP red chip, and green and yellow silicate phosphors increased by 19-49% when compared with that of excellent CRI p-W LEDs with one InGaN blue chip and green and yellow silicate phosphors, as well as red nitride phosphor.

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.

DOE Chair of Excellence Professorship in Environmental Disciplines  

SciTech Connect

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.

Savannah River Plant Business Services Department's Commitment To Excellence  

SciTech Connect

The Savannah River Plant (SRP) is located in South Carolina approximately 20 miles southeast of Augusta, Georgia. Today, the total work force level exceeds 18,000 employees including operations, research, and construction personnel. The site is proud of its safety and operating performance during its 38+ years' history. The site is the single largest employer and has the highest payroll in the state of South Carolina. Total land area exceeds 325 square miles. Du Pont built the Plant for the government and then operated it from the time construction was completed in 1953 until March 31, 1989, when Westinghouse Electric Corporation took over. During Du Pont's tenure the Plant was operated under the same corporate policies and procedures as all other Du Pont facilities. In the latter part of the 1970s and into the 1980s, most Du Pont manufacturing facilities began experimenting with changes designed to enhance organizational effectiveness (OE). The success of these efforts in its commercial business led Du Pont corporate executives to insist that SRP undertake similar improvement efforts which finally culminated in SRP's Commitment To Excellence (CTE) program.

Best Practices in Academic Mentoring: A Model for Excellence  

PubMed Central

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.

Chemical Punch Packed in Venoms Makes Centipedes Excellent Predators*  

PubMed Central

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.

Advanced Modeling in Excel: from Water Jets to Big Bang  

NASA Astrophysics Data System (ADS)

An international students’ project is presented focused on application of Open Office and Excel spreadsheets for modeling of projectile-motion type dynamical systems. Variation of the parameters of plotted and animated families of jets flowing at different angles out of the holes in the wall of water-filled reservoir [1,2] revealed unexpected peculiarities of the envelopes, vertices, intersections and landing points of virtual trajectories. Comparison with real-life systems and rigorous calculations were performed to prove predictions of computer experiments. By same technique, the kinematics of fireworks was analyzed. On this basis two-dimensional ‘firework’ computer model of Big Bang was designed and studied, its relevance and limitations checked. 1.R.Ehrlich, Turning the World Inside Out, (Princeton University Press, Princeton, NJ, 1990), pp. 98-100. 2.A.Kazachkov, Yu.Bogdan, N.Makarovsky, N.Nedbailo.

Center of Excellence in Model-Based Human Performance  

NASA Technical Reports Server (NTRS)

The Center of Excellence (COE) was created in 1984 to facilitate active collaboration between the scientists at Ames Research Center and the Stanford Psychology Department. 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.

A faculty created strategic plan for excellence in nursing education.  

PubMed

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

Well-being and excellence in the Earth sciences  

NASA Astrophysics Data System (ADS)

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.

Light! Spectra! Action! Excellent astronomical experiences for a diverse audience  

NASA Astrophysics Data System (ADS)

Adler Planetarium and Astronomy Museum creates "excellent audience experiences" through a process of prototyping and evaluation. We try to find good projects to replicate or adapt and good partners to reduce the effort, achieve higher quality, or multiply the impact of exhibits, shows, and programs. Adler recently created the exhibit Light! Spectra! Action! based on exhibits about light originally developed by the Exploratorium. Exhibit labels and captions appropriate to astronomy were written and extensively revised based on prototyping with test audiences (the exhibit is designed for ages 8 - adult). Demonstrations and photographs (some based on previous activities) about color, light, and spectra are incorporated in the exhibit. Photographs were enthusiastically provided by David Malin/Anglo Australian Observatory, the Astronomical Society of the Pacific, The Space Telescope Science Institute, Roger Ressmeyer, and Kitt Peak National Observatory. The exhibit's impact is being enhanced by a NASA Idea Grant which supported some of the original construction and enables Kitt Peak to replicate parts of the exhibit for their Visitor Center.

Manganese dioxide modified silicon nanowires and their excellent catalysis in the decomposition of methylene blue  

NASA Astrophysics Data System (ADS)

A redox between hydrofluoric acid and ammonium fluoride-treated silicon nanowires and potassium permanganate solution was investigated. The results showed that MnO2 nanoparticles might grow on the surface of silicon nanowires, which was confirmed with the transmission electron microscope. These MnO2 modified silicon nanowires were employed as catalysts in the decomposition of methylene blue using sodium borohydride as the reducing agent, which exhibited excellent catalysis with its reaction rate 6 times larger than the unsupported MnO2.

Excellent p-n control in a high temperature thermoelectric boride  

NASA Astrophysics Data System (ADS)

Polycrystalline samples of YxAlyB14 (x ~ 0.57) with different fractional occupancies y (0.41 <= y <= 0.63) were synthesized and their thermoelectric properties investigated. Electrical conductivities generally followed three-dimensional variable range hopping with a rapid delocalization indicated as electrons were increased. Positive Seebeck coefficients were obtained for the Al-poor sample, y = 0.41, which was shifted in the negative direction with increase of y. Maximum Seebeck coefficient values were approximately 400 ?V K-1 at 850 K and -200 ?V K-1 at 1000 K, for p-type and n-type, respectively. Excellent control of p-n characteristics was achieved in a system with the same crystal structure and consisting of the same elements.

This study introduces multi-package white light-emitting diodes (LEDs) system with the ability to realize high luminous efficacy and an excellent color rendering index (CRI, R a) using the R B,M A B,M G B,M C B (R B,M A B,M G B,M denoted as a long-pass dichroic filter (LPDF)-capped, monochromatic red, amber and green phosphor converted-LED (pc-LED) pumped by a blue LED chip, and C B denoted as a cyan and blue mixed pc-LED pumped by a blue LED) system. The luminous efficacy and color rendering index (CRI) of multi-package white LED systems are compared while changing the concentration of the cyan phosphor used in the paste of a cyan-blue LED package and the driving current of individual LEDs in multi-package white LEDs at correlated color temperatures (CCTs) ranging from 6,500 K (cold white) to 2,700 K (warm white) using a set of eight CCTs as specified by the American National Standards Institute (ANSI) standard number C78.377-2008. A R B,M A B,M G B,M C B white LED system provides high luminous efficacy (? 96 lm/W) and a color rendering index (? 91) encompassing the complete CCT range. We also compare the optical properties of the R B,M A B,M G B,M C B system with those of the R B,M A B,M G B,M B and RAGB (red, amber, green, and blue semiconductor-type narrow-spectrum-band LEDs) systems. It can be expected that the cyan color added to a blue LED in multi-package white LEDs based on LPDF-capped, phosphor-converted monochromatic LEDs will meet the needs of the high-quality, highly efficient, full-color white LED lighting market in the near future.

This work develops a facile and environment-friendly method for preparing the superhydrophobic aluminium alloy surface with excellent corrosion resistance. The superhydrophobic aluminium alloy surface is fabricated by the boiling water treatment and stearic acid (STA) modification. Results show that the boiling water treatment endows the aluminium alloy surface with a porous and rough structure, while STA modification chemically grafts the long hydrophobic alkyl chains onto the aluminium alloy surface. Just grounded on the micro- and nano-scale hierarchical structure along with the hydrophobic chemical composition, the superhydrophobic aluminium alloy surface is endued the excellent corrosion resistance.

Proton-functionalized two-dimensional graphitic carbon nitride nanosheet: an excellent metal-/label-free biosensing platform.  

PubMed

Ultrathin graphitic carbon nitride (g-C3 N4 ) nanosheets, due to their interesting two-dimensional graphene-like structure and unique physicochemical properties, have attracted great research attention recently. Here, a new approachis developed to prepare, for the first time, proton-functionalized ultrathin g-C3 N4 nanosheets by sonication-exfoliation of bulk g-C3 N4 under an acid condition. This method not only reduces the exfoliation time from more than 10 h to 2 h, but also endows the nanosheets with positive charges. Besides retaining the properties of g-C3 N4 , the obtained nanosheets with the thickness of 2-4 nm (i.e., 6-12 atomic monolayers) also exhibit large specific surface area of 305 m(2) g(-1) , enhanced fluorescence intensity, and excellent water dispersion stability due to their surface protonation and ultrathin morphology. The well-dispersed protonated g-C3 N4 nanosheets are able to interact with negatively charged heparin, which results in the quenching of g-C3 N4 fluorescence. A highly sensitive and highly selective heparin sensing platform based on protonated g-C3 N4 nanosheets is established. This metal-free and fluorophore label-free system can reach the lowest heparin detection limit of 18 ng mL(-1) . PMID:24596304

The Pt-Enriched PtNi Alloy Surface and its Excellent Catalytic Performance in Hydrolytic Hydrogenation of Cellulose.  

PubMed

Ni-based catalysts are currently a subject of intense research in the hydrolytic hydrogenation of cellulose. We previously reported that Ni/ZSM-5 catalyst gave high yield of hexitols. However, Ni-based catalysts suffered fast deactivation in hot-compressed water. In this follow-up study we designed highly active Ni-based bimetallic catalysts with excellent hydrothermal stability for the hydrolytic hydrogenation of microcrystalline cellulose. PtNi/ZSM-5 shows a 76.9?% yield of hexitols, which is the best obtained so far in the hydrolytic hydrogenation of microcrystalline cellulose over Ni-based catalysts. Furthermore, the yield of hexitols remained greater than 55?% after the catalyst was reused for 4?times. The results showed that PtNi nanoparticles were formed with a Pt-enriched alloy surface as confirmed by XRD, H2 -TPR (temperature-programmed H2 reduction), XPS (X-ray photoelectron spectroscopy), and H2 -TPD (temperature-programmed H2 desorption). The surface features of these nano-particles were characterized by CO-TPD (temperature-programmed CO desorption), CO-FTIR (CO adsorption FTIR spectroscopy), HRTEM (high resolution TEM), and O2 -TPO (temperature programmed oxidation) and this special surface structure may be responsible for the high activity, selectivity, and stability in the hydrolytic hydrogenation of cellulose in hot-compressed water.

EDCTP regional networks of excellence: initial merits for planned clinical trials in Africa  

PubMed Central

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.

Mesoporous silica nanospheres decorated with CdS nanocrystals for enhanced photocatalytic and excellent antibacterial activities.  

PubMed

Uniform SiO2@CdS mesoporous nanospheres with an average diameter of 300 nm have been synthesized successfully by a facile process. The as-prepared mesoporous composite nanospheres have a BET-specific surface area of 640 m(2) g(-1) and an average pore size of 2.82 nm. The results demonstrated that more than 60% Rhodamine B (RhB) dye in solution (4.8 mg L(-1), 50 mL) could be removed by adsorption in the dark for 30 min using the as-prepared SiO2@CdS mesoporous nanospheres (40 mg). The as-prepared SiO2@CdS mesoporous nanospheres have a mesoporous nanostructure, suggesting a higher specific surface area and resulting in a strong adsorption ability. In addition, the mesoporous silica was decorated with ca. 5 nm CdS nanocrystals, which showed excellent photocatalytic activity under visible light and could rapidly remove most of the RhB molecules from a pollutant solution under visible light irradiation. Furthermore, the mesoporous SiO2@CdS nanospheres synthesized by the present protocol exhibited excellent antibacterial activity. PMID:23760602

Plasma-sprayed CaTiSiO5 ceramic coating on Ti-6Al-4V with excellent bonding strength, stability and cellular bioactivity.  

PubMed

Novel Ca-Si-Ti-based sphene (CaTiSiO5) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study was to prepare sphene coating on titanium alloy (Ti-6Al-4V) for orthopaedic applications using the plasma spray method. The phase composition, surface and interface microstructure, coating thickness, surface roughness and bonding strength of the plasma-sprayed sphene coating were analysed using X-ray diffraction, scanning electron microscopy, atomic force microscopy and the standard mechanical testing of the American Society for Testing and Materials, respectively. The results indicated that sphene coating was obtained with a uniform and dense microstructure at the interface of the Ti-6Al-4V surface and the thickness and surface roughness of the coating were approximately 150 and 10 microm, respectively. Plasma-sprayed sphene coating on Ti-6Al-4V possessed a significantly improved bonding strength and chemical stability compared with plasma-sprayed hydroxyapatite (HAp) coating. Plasma-sprayed sphene coating supported human osteoblast-like cell (HOB) attachment and significantly enhanced HOB proliferation and differentiation compared with plasma-sprayed HAp coating and uncoated Ti-6Al-4V. Taken together, plasma-sprayed sphene coating on Ti-6Al-4V possessed excellent bonding strength, chemical stability and cellular bioactivity, indicating its potential application for orthopaedic implants.

Current Lewis Turbomachinery Research: Building on our Legacy of Excellence  

NASA Technical Reports Server (NTRS)

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.

PKSolver: An add-in program for pharmacokinetic and pharmacodynamic data analysis in Microsoft Excel.  

PubMed

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

Seismic hazard analyses for Taipei city including deaggregation, design spectra, and time history with excel applications  

NASA Astrophysics Data System (ADS)

Given the difficulty of earthquake forecast, Probabilistic Seismic Hazard Analysis (PSHA) has been a method to best estimate site-specific ground motion or response spectra in earthquake engineering and engineering seismology. In this paper, the first in-depth PSHA study for Taipei, the economic center of Taiwan with a six-million population, was carried out. Unlike the very recent PSHA study for Taiwan, this study includes the follow-up hazard deaggregation, response spectra, and the earthquake motion recommendations. Hazard deaggregation results show that moderate-size and near-source earthquakes are the most probable scenario for this city. Moreover, similar to the findings in a few recent studies, the earthquake risk for Taipei should be relatively high and considering this city's importance, the high risk should not be overlooked and a potential revision of the local technical reference would be needed. In addition to the case study, some innovative Excel applications to PSHA are introduced in this paper. Such spreadsheet applications are applicable to geosciences research as those developed for data reduction or quantitative analysis with Excel's user-friendly nature and wide accessibility.

The journey toward geriatric excellence in a non-research-intensive university.  

PubMed

In response to the unprecedented rise in the U.S. older adult population, nurse educators have intensified efforts to produce graduates who are sensitive to older adults' health care concerns. Critical to accomplishing this goal is strengthening curricula to include specialized gerontological content. Although the science of gerontological nursing has grown significantly over the past several decades, large-scale research projects are often confined to research or doctoral level universities in which typically more support is available. Faculty members in smaller universities in which a great number of nursing students are educated do not always have the resources to readily contribute to science. Such a challenge was faced by one nursing school in a small Jesuit New England university. This article illustrates a process to develop excellence in gerontological nursing education, as well as to promote scholarship and collaboration among faculty members at baccalaureate or master's level universities. Three years ago, the John A. Hartford Foundation, in collaboration with the American Association of Colleges of Nursing, awarded grants to select nursing programs for curricular enhancement. Implementation of this project at a small Jesuit university led to synergy among faculty that resulted in joint publications, presentations, and newly funded projects. In addition, the school earned local and national recognition for excellence in gerontological nursing education/care. The process leading to the outstanding success of this curricular endeavor is presented as a replicable model for schools in other baccalaureate or master's level settings. PMID:16564472

MinSORTING: An Excel® worksheet for modelling mineral grain-size distribution in sediments, with application to detrital geochronology and provenance studies  

NASA Astrophysics Data System (ADS)

MinSORTING is an Excel® spreadsheet devised to model mineral distributions in different size-classes within sediment samples and maximize mineral recovery during separation procedures for single-grain analysis. It is based on the physical laws of settling by tractive currents, both in water and air, applied to the different minerals in silt to sand-sized terrigenous sediments. Input values are: (i) grain size and sorting, (ii) depositional medium (seawater, freshwater or air), (iii) sediment composition (selected from a range of tectonic settings). The software's output includes the distribution of 27 different detrital components contained in sediments in size intervals of 0.25, 0.5, or 1 phi. Researchers can thus select the most appropriate size window for their own analyses and obtain valuable information on the amount of minerals lost in finer and coarser grain-size classes, allowing to accurately constrain the significance of their results.

An ordered Si nanowire with NiSi2 tip arrays as excellent field emitters  

NASA Astrophysics Data System (ADS)

A method was developed to grow ordered silicon nanowire with NiSi2 tip arrays by reacting nickel thin films on silica-coated ordered Si nanowire (NW) arrays. The coating of thin silica shell on Si NW arrays has the effect of limiting the diffusion of nickel during the silicidation process to achieve the single crystalline NiSi2 NWs. In the meantime, it relieves the distortion of the NWs caused by the strain associated with formation of NiSi2 to maintain the straightness of the nanowire and the ordering of the arrays. Other nickel silicide phases such as Ni2Si and NiSi were obtained if the silicidation processes were conducted on the ordered Si NWs without a thin silica shell. Excellent field emission properties were found for NiSi2/Si NW arrays with a turn on field of 0.82 V µm - 1 and a threshold field of 1.39 V µm - 1. The field enhancement factor was calculated to be about 2440. The stability test showed a fluctuation of about 7% with an applied field of 2.6 V µm - 1 for a period of 24 h. The excellent field emission characteristics are attributed to the well-aligned and highly ordered arrangement of the single crystalline NiSi2/Si heterostructure field emitters. In contrast to other growth methods, the present growth of ordered nickel silicide/Si NWs on silicon is compatible with silicon nanoelectronics device processes, and also provides a facile route to grow other well-aligned metal silicide NW arrays. The advantages will facilitate its applications as field emission devices.

A Simple Tool for Integration and Differentiation of Tabular Values in Microsoft Excel  

NASA Astrophysics Data System (ADS)

There are many software alternatives for analyzing experimental data in our physics teaching. I prefer to use Excel® because of its flexibility and widespread use elsewhere in our society. Whatever our students will work with in their future career, they almost certainly will have access to a spreadsheet. For a long time I have missed a tool for integrating and differentiating tabular values in Excel. For every new version I thought it would appear, but it did not. Such a tool could also be useful if you analyze data from other sources than your own experiment, for example, data from the Internet. Therefore, I have written a simple tool that can be integrated seamlessly into Excel as an add-in. It is written in Excels powerful macro language Microsoft Visual Basic for Applications. The tool can be downloaded online1 and there are two versions of it: one for Excel 2003 and one for Excel 2007/2010.

Teaching excellence and achivement in mathematics and science  

SciTech Connect

This was a collaborative effort of Iowa State Univ. (College of Ed.), Ames, and the Ames Community Schools. Teams of four preservice teachers, one scientist, one classroom teacher, and one teacher educator were formed. Students in the project participated in a laboratory experience for 2 h/week, participated in a classroom experience for 2 hr/week, and attended seminar for 1 h/week. At end of each semester, studies and their cooperating scientists taught a lesson that included some of the material the students had worked with in the science laboratory. Results from interviews of project participants indicate that preservice teachers attitude and self concept toward science improved during the project. Results also suggest methods for making similar collaborative projects using scientists and teachers effective.

Intelligent processing equipment developments within the Navy's Manufacturing Technology Centers of Excellence  

NASA Astrophysics Data System (ADS)

The U.S. Navy has had an active Manufacturing Technology (MANTECH) Program aimed at developing advanced production processes and equipment since the late-1960's. During the past decade, however, the resources of the MANTECH program were concentrated in Centers of Excellence. Today, the Navy sponsors four manufacturing technology Centers of Excellence: the Automated Manufacturing Research Facility (AMRF); the Electronics Manufacturing Productivity Facility (EMPF); the National Center for Excellence in Metalworking Technology (NCEMT); and the Center of Excellence for Composites Manufacturing Technology (CECMT). This paper briefly describes each of the centers and summarizes typical Intelligent Equipment Processing (IEP) projects that were undertaken.
