  1. Distribution load estimation (DLE)

    Energy Technology Data Exchange (ETDEWEB)

    Seppaelae, A.; Lehtonen, M. [VTT Energy, Espoo (Finland)


    The load research has produced customer class load models to convert the customers` annual energy consumption to hourly load values. The reliability of load models applied from a nation-wide sample is limited in any specific network because many local circumstances are different from utility to utility and time to time. Therefore there is a need to find improvements to the load models or, in general, improvements to the load estimates. In Distribution Load Estimation (DLE) the measurements from the network are utilized to improve the customer class load models. The results of DLE will be new load models that better correspond to the loading of the distribution network but are still close to the original load models obtained by load research. The principal data flow of DLE is presented

  2. Distribution load estimation - DLE

    Seppaelae, A. [VTT Energy, Espoo (Finland)


    The load research project has produced statistical information in the form of load models to convert the figures of annual energy consumption to hourly load values. The reliability of load models is limited to a certain network because many local circumstances are different from utility to utility and time to time. Therefore there is a need to make improvements in the load models. Distribution load estimation (DLE) is the method developed here to improve load estimates from the load models. The method is also quite cheap to apply as it utilises information that is already available in SCADA systems

  3. Multi-kernel deconvolution for contrast improvement in a full field imaging system with engineered PSFs using conical diffraction (United States)

    Enguita, Jose M.; Álvarez, Ignacio; González, Rafael C.; Cancelas, Jose A.


    The problem of restoration of a high-resolution image from several degraded versions of the same scene (deconvolution) has been receiving attention in the last years in fields such as optics and computer vision. Deconvolution methods are usually based on sets of images taken with small (sub-pixel) displacements or slightly different focus. Techniques based on sets of images obtained with different point-spread-functions (PSFs) engineered by an optical system are less popular and mostly restricted to microscopic systems, where a spot of light is projected onto the sample under investigation, which is then scanned point-by-point. In this paper, we use the effect of conical diffraction to shape the PSFs in a full-field macroscopic imaging system. We describe a series of simulations and real experiments that help to evaluate the possibilities of the system, showing the enhancement in image contrast even at frequencies that are strongly filtered by the lens transfer function or when sampling near the Nyquist frequency. Although results are preliminary and there is room to optimize the prototype, the idea shows promise to overcome the limitations of the image sensor technology in many fields, such as forensics, medical, satellite, or scientific imaging.

  4. Opportunities and Internationalisation of PSFs

    DEFF Research Database (Denmark)

    Jensen, Søren Henning; Poulfelt, Flemming


    The article focuses on the relationship between internationalisation and opportunities of firms within the professional services industry. The key question explored is whether internationalisation of PSFs is a passive strategy driven by clients' internationalisation or if it is a deliberate search...... for opportunities that drives the internationalisation processes. This is being analysed by scrutinising the literature to check if this perspective can be understood and explained from an opportunity angle. The paper shows that there is no apparent pattern among the various PSF articles that relates...... to the particular take on internationalisation for the individual article and therefore shows the same variation....

  5. DLE combustor exceeds performance guarantees

    Davidson, John; Leonard, Gary [GE Marine and Industrial Engines, Evendale, OH (United States)


    The 50MW Gent power station in Belgium started operating in 1994 using General Electric`s high efficiency LM6000 gas turbine. This article describes performance testing of the new Dry Low Emissions (DLE) combustion system fitted to the aeroderivative gas turbine, which has allowed the combined cycle, cogeneration facility to function at full-power, with low emissions of nitrogen oxides, carbon monoxide, and unburned hydrocarbons. Conventional combustion systems are compared to the new premixed lean combustor used here. (UK)

  6. Study on Performance Shaping Factors (PSFs) Quantification Method in Human Reliability Analysis (HRA)

    The purpose of HRA implementation is 1) to achieve the human factor engineering (HFE) design goal of providing operator interfaces that will minimize personnel errors and 2) to conduct an integrated activity to support probabilistic risk assessment (PRA). For these purposes, various HRA methods have been developed such as technique for human error rate prediction (THERP), simplified plant analysis risk human reliability assessment (SPAR-H), cognitive reliability and error analysis method (CREAM) and so on. In performing HRA, such conditions that influence human performances have been represented via several context factors called performance shaping factors (PSFs). PSFs are aspects of the human's individual characteristics, environment, organization, or task that specifically decrements or improves human performance, thus respectively increasing or decreasing the likelihood of human errors. Most HRA methods evaluate the weightings of PSFs by expert judgment and explicit guidance for evaluating the weighting is not provided. It has been widely known that the performance of the human operator is one of the critical factors to determine the safe operation of NPPs. HRA methods have been developed to identify the possibility and mechanism of human errors. In performing HRA methods, the effect of PSFs which may increase or decrease human error should be investigated. However, the effect of PSFs were estimated by expert judgment so far. Accordingly, in order to estimate the effect of PSFs objectively, the quantitative framework to estimate PSFs by using PSF profiles is introduced in this paper.

  7. The M 4 Core Project with HST - V. Characterizing the PSFs of WFC3/UVIS by focus★ (United States)

    Anderson, J.; Bedin, L. R.


    As part of the astrometric Hubble Space Telescope (HST) large program GO-12911, we conduct an in-depth study to characterize the point spread function (PSF) of the Uv-VISual channel of the Wide Field Camera 3 (WFC3), as a necessary step to achieve the astrometric goals of the program. We extracted a PSF from each of the 589 deep exposures taken through the F467M filter over the course of a year and find that the vast majority of the PSFs lie along a 1-D locus that stretches continuously from one side of focus, through optimal focus, to the other side of focus. We constructed a focus-diverse set of PSFs and find that with only five medium-bright stars in an exposure it is possible to pin down the focus level of that exposure. We show that the focus-optimized PSF does a considerably better job fitting stars than the average 'library' PSF, especially when the PSF is out of focus. The fluxes and positions are significantly improved over the 'library' PSF treatment. These results are beneficial for a much broader range of scientific applications than simply the program at hand, but the immediate use of these PSFs will enable us to search for astrometric wobble in the bright stars in the core of the globular cluster M 4, which would indicate a dark, high-mass companion, such as a white dwarf, neutron star or black hole.

  8. Successful Treatment of Resistant Discoid Lupus Erythematous (DLE With Low-Level Laser Therapy (LLLT: A Case Report

    Directory of Open Access Journals (Sweden)

    Nooshafarin Kazemikhoo


    Full Text Available Introduction Lupus is a chronic autoimmune illness characterized by production of autoantibodies against nuclear antigens. Lupus may also only appear as a skin disease. Discoid lupus erythematous (DLE, the most common form of chronic cutaneous lupus erythematous is characterized by patches of persistent erythema, adherent scaling, follicular plugging and, in the later stages scaring and atrophy. Case Presentation The case was a 33-year-old female with two years history of DLE, who referred to the laser clinic of Milad hospital with acute flare of skin lesions since seven months ego. She had four lesions (three with local alopecia, scaling and itching and one with atrophy. Serological studies for antinuclear antibodies and anti Ro/SS-A antibody were negative. After five sessions of treatment with infrared (830 nm; 200 mw and red light (630 nm; 20 mw diode laser in addition to intravenous red light laser (655 nm; 2 mw for 20 minutes and laser acupuncture with infrared diode laser (1 J/cm2 for six acupuncture points every other day, the beneficial effects started to appear, and after nine sessions, local itching of the lesions had stopped. Through a total of 27 sessions of treatment, the lesions improved completely with highly satisfactory results; and drug-therapy held to be continued. No disease flare up was seen after the one-year follow up. Conclusions To the best of our knowledge, this is the first case report on low-level laser therapy (LLLT treatment of DLE. Low-level laser therapy may be effective in treating inflammatory lesions such as cutaneous lesions of discoid lupus erythematous. More studies with higher sample size are needed to clarify the role of low level lasers in treating such lesions.

  9. Subsurface volatile content of martian double-layer ejecta (DLE) craters (United States)

    Viola, Donna; McEwen, Alfred S.; Dundas, Colin M.; Byrne, Shane


    Excess ice is widespread throughout the martian mid-latitudes, particularly in Arcadia Planitia, where double-layer ejecta (DLE) craters also tend to be abundant. In this region, we observe the presence of thermokarstically-expanded secondary craters that likely form from impacts that destabilize a subsurface layer of excess ice, which subsequently sublimates. The presence of these expanded craters shows that excess ice is still preserved within the adjacent terrain. Here, we focus on a 15-km DLE crater that contains abundant superposed expanded craters in order to study the distribution of subsurface volatiles both at the time when the secondary craters formed and, by extension, remaining today. To do this, we measure the size distribution of the superposed expanded craters and use topographic data to calculate crater volumes as a proxy for the volumes of ice lost to sublimation during the expansion process. The inner ejecta layer contains craters that appear to have undergone more expansion, suggesting that excess ice was most abundant in that region. However, both of the ejecta layers had more expanded craters than the surrounding terrain. We extrapolate that the total volume of ice remaining within the entire ejecta deposit is as much as 74 km3 or more. The variation in ice content between the ejecta layers could be the result of (1) volatile preservation from the formation of the DLE crater, (2) post-impact deposition in the form of ice lenses; or (3) preferential accumulation or preservation of subsequent snowfall. We have ruled out (2) as the primary mode for ice deposition in this location based on inconsistencies with our observations, though it may operate in concert with other processes. Although none of the existing DLE formation hypotheses are completely consistent with our observations, which may merit a new or modified mechanism, we can conclude that DLE craters contain a significant quantity of excess ice today.

  20. Antibody Fc engineering improves frequency and promotes kinetic boosting of serial killing mediated by NK cells. (United States)

    The efficacy of most therapeutic monoclonal antibodies (mAbs) targeting tumor antigens results primarily from their ability to elicit potent cytotoxicity through effector-mediated functions. We have engineered the fragment crystallizable (Fc) region of the immunoglobulin G (IgG) mAb, HuM195, targeting the leukemic antigen CD33, by introducing the triple mutation Ser293Asp/Ala330Leu/Ile332Glu (DLE), and developed Time-lapse Imaging Microscopy in Nanowell Grids to analyze antibody-dependent cell-mediated cytotoxicity kinetics of thousands of individual natural killer (NK) cells and mAb-coated target cells. We demonstrate that the DLE-HuM195 antibody increases both the quality and the quantity of NK cell-mediated antibody-dependent cytotoxicity by endowing more NK cells to participate in cytotoxicity via accrued CD16-mediated signaling and by increasing serial killing of target cells. NK cells encountering targets coated with DLE-HuM195 induce rapid target cell apoptosis by promoting simultaneous conjugates to multiple target cells and induce apoptosis in twice the number of target cells within the same period as the wild-type mAb. Enhanced target killing was also associated with increased frequency of NK cells undergoing apoptosis, but this effect was donor-dependent. Antibody-based therapies targeting tumor antigens will benefit from a better understanding of cell-mediated tumor elimination, and our work opens further opportunities for the therapeutic targeting of CD33 in the treatment of acute myeloid leukemia. © 2014 by The American Society of Hematology.

    Interferon-γ (IFNγ) is implicated in the pathogenesis of discoid lupus erythematosus (DLE). This study sought to evaluate a single dose of AMG 811, an anti-IFNγ antibody, in patients with DLE. The study was designed as a phase I randomized, double-blind, placebo-controlled crossover study of the pharmacodynamics, safety, and clinical efficacy of AMG 811 in patients with DLE. Patients received a single subcutaneous dose of AMG 811 (180 mg) or placebo. The patients in sequence 1 received AMG 811 followed by placebo, while those in sequence 2 received placebo followed by AMG 811. Pharmacodynamic end points included global transcriptional analyses of lesional and nonlesional skin, IFNγ blockade signature (IGBS) transcriptional scores in the skin and blood, keratinocyte IFNγ RNA scores, and serum levels of CXCL10 protein. Additional end points were efficacy outcome measures, including the Cutaneous Lupus Erythematosus Disease Area and Severity Index, and safety outcome measures. Sixteen patients with DLE were enrolled in the study (9 in sequence 1 and 7 in sequence 2). AMG 811 treatment reduced the IGBS score (which was elevated in DLE patients at baseline) in both the blood and lesional skin. The keratinocyte IFNγ RNA score was not affected by administration of AMG 811. Serum CXCL10 protein levels (which were elevated in the blood of DLE patients) were reduced with AMG 811 treatment. The AMG 811 treatment was well tolerated but did not lead to statistically significant improvements in any of the efficacy outcome measures. AMG 811 treatment led to changes in IFNγ-associated biomarkers and was well tolerated, but no significant clinical benefit was observed in patients with DLE. © 2017 The Authors.

  4. Improving photosynthesis. (United States)

    Evans, John R


    Photosynthesis is the basis of plant growth, and improving photosynthesis can contribute toward greater food security in the coming decades as world population increases. Multiple targets have been identified that could be manipulated to increase crop photosynthesis. The most important target is Rubisco because it catalyses both carboxylation and oxygenation reactions and the majority of responses of photosynthesis to light, CO₂, and temperature are reflected in its kinetic properties. Oxygenase activity can be reduced either by concentrating CO₂ around Rubisco or by modifying the kinetic properties of Rubisco. The C₄ photosynthetic pathway is a CO₂-concentrating mechanism that generally enables C₄ plants to achieve greater efficiency in their use of light, nitrogen, and water than C₃ plants. To capitalize on these advantages, attempts have been made to engineer the C₄ pathway into C₃ rice (Oryza sativa). A simpler approach is to transfer bicarbonate transporters from cyanobacteria into chloroplasts and prevent CO₂ leakage. Recent technological breakthroughs now allow higher plant Rubisco to be engineered and assembled successfully in planta. Novel amino acid sequences can be introduced that have been impossible to reach via normal evolution, potentially enlarging the range of kinetic properties and breaking free from the constraints associated with covariation that have been observed between certain kinetic parameters. Capturing the promise of improved photosynthesis in greater yield potential will require continued efforts to improve carbon allocation within the plant as well as to maintain grain quality and resistance to disease and lodging.

    Full Text Available Traditional steel ties reinforcement cannot provide superior confinement for reinforced concrete (RC columns due to the constraints on tie spacing and disturbance of concrete continuity. This paper presents a practical confinement configuration consisting of single Expanded Metal Mesh (EMM layer in additional to regular tie reinforcement. The EMM layer is warped above ties. The proposed transverse reinforcement, with various volumetric ratios of ties, was investigated in sixteen square short RC column specimens categorized in two groups according to their slenderness ratios. The specimens were cast in vertical position simulating the construction field and they were tested under concentric compression till failure. The results indicated that the columns, confined with proposed lateral reinforcement, revealed significant improvement in the strength and ductility. Also, high reduction in ties volumetric ratio with no loss in ultimate load could be achieved by installing the EMM layer.

  12. A Study of PSF Models for ACS/WFC (United States)

    Hoffmann, S. L.; Anderson, J.


    This study compares PSFs generated with Tiny Tim against an empirically-derived, effective PSF (Anderson & King, 2006) for the Hubble Space Telescope Advanced Camera for Surveys/Wide Field Channel imaging. We manipulate the Tiny Tim PSF FITS files into a format that can be utilized by the effective PSF FORTRAN photometry code. Then we perform PSF photometry on globular cluster NGC 6397 and analyze the photometry and astrometry results. We measure a value of 0.227 ± 0.032 for a quality-of-fit metric of the Tiny Tim PSF and a corresponding 0.117 ± 0.021 for the effective PSFs, an improvement of a factor of approximately two. We find that the effective PSF models outperform the Tiny Tim PSFs in every measurement of stellar sources in this field.

  16. Improving employee productivity through improved health. (United States)

    Mitchell, Rebecca J; Ozminkowski, Ronald J; Serxner, Seth


    The objective of this study was to estimate productivity-related savings associated with employee participation in health promotion programs. Propensity score weighting and multiple regression techniques were used to estimate savings. These techniques were adjusted for demographic and health status differences between participants who engaged in one or more telephonic health management programs and nonparticipants who were eligible for but did not engage in these programs. Employees who participated in a program and successfully improved their health care or lifestyle showed significant improvements in lost work time. These employees saved an average of $353 per person per year. This reflects about 10.3 hours in additional productive time annually, compared with similar, but nonparticipating employees. Participating in health promotion programs can help improve productivity levels among employees and save money for their employers.

  17. Improved phytonutrient content through plant genetic improvement. (United States)

    Farnham, M W; Simon, P W; Stommel, J R


    During the twentieth century, plant breeding and genetics improved the nutritive value of horticultural and agronomic crops, particularly of macronutrients and fiber. Current research focuses more on micronutrients. Successful development of phytonutrient-enriched crop plants will be bolstered by interdisciplinary collaborative research, analytical and biotechnology advances, and public education. Although the melding of plant and nutrition research holds great promise, the genetic enhancement of crop plants for improved phytonutrient content will be challenging. This paper reviews the knowledge base on which genetic enhancement may be based, identifies gaps in scientific knowledge and technical capacities, and suggests a role for the federal government in research.

  4. Improving theatre turnaround time. (United States)

    Fletcher, Daniel; Edwards, David; Tolchard, Stephen; Baker, Richard; Berstock, James


    The NHS Institute for Innovation and Improvement has determined that a £7 million saving can be achieved per trust by improving theatre efficiency. The aim of this quality improvement project was to improve orthopaedic theatre turnaround without compromising the patient safety. We process mapped all the stages from application of dressing to knife to skin on the next patient in order to identify potential areas for improvement. Several suggestions arose which were tested in multiple PDSA cycles in a single theatre. These changes were either adopted, adapted or rejected on the basis of run chart data and theatre team feedback. Successful ideas which were adopted included, the operating department practitioner (ODP) seeing and completing check-in paperwork during the previous case rather than during turnaround, a 15 minute telephone warning to ensure the next patient was fully ready, a dedicated cleaning team mobilised during wound closure, sending for the next patient as theatre cleaning begins. Run charts demonstrate that as a result of these interventions the mean turnaround time almost halved from 66.5 minutes in July to 36.8 minutes over all PDSA cycles. This improvement has been sustained and rolled out into another theatre. As these improvements become more established we hope that additional cases will be booked, improving theatre output. The PDSA cycle continues as we believe that further gains may yet be made, and our improvements may be rolled out across other surgical specialities.

    We formulate a model of vertical differentiation to evaluate the welfare effects of removing a low quality product from the market. The mechanism through which a welfare improvement might arise is simple: Once the low quality low cost alternative is banned, entry into the high quality segment becomes more likely. This in turn may lead to a significant reduction in the price of the high quality product. We find that such a ban might improve aggregate welfare when consumers value the higher qua...

  17. Improved rational hydrograph method (United States)

    Crobeddu, E.; Bennis, S.; Rhouzlane, S.


    SummaryThis paper presents an improved rational hydrograph method to compute the runoff at the outlet of a small urban catchment. The new formulation, based on the linear system theory, explicitly considers the contributions of pervious and impervious areas, the time variability of rainfall, the initial abstraction on impervious areas and the infiltration on pervious areas. Moreover, the rational method formula appears to be a special case of the proposed rational hydrograph method. A sensitivity analysis conducted on the improved rational hydrograph method has emphasized the most influent parameters. A sequential procedure is proposed to calibrate parameters of the improved rational hydrograph method on the basis of appropriate storm events. The improved rational hydrograph method was applied to 41 rainfall events gauged in 7 different North American and European urban catchments. Runoff computed with the improved rational hydrograph method was compared to measured runoff, as well as to the runoff derived from the nonlinear reservoir model. A good agreement was achieved between simulated and observed runoff hydrographs. Moreover, runoff hydrographs derived with the proposed method are equivalent to those computed with the nonlinear reservoir model.

  18. Proposal Improvements That Work (United States)

    Dunn, F.


    Rocketdyne Propulsion and Power, an operating location of Boeing in Canoga Park, California is under contract with NASA's Marshall Space Flight Center (MSFC) in Huntsville, Alabama for design, development, production, and mission support of Space Shuttle Main Engines (SSMEs). The contract was restructured in 1996 to emphasize a mission contracting environment under which Rocketdyne supports the Space Transportation System launch manifest of seven flights a year without the need for a detailed list of contract deliverables such as nozzles, turbopumps, and combustion devices. This contract structure is in line with the overall Space Shuttle program goals established by the NASA to fly safely, meet the flight manifest, and reduce cost. Rocketdyne's Contracts, Pricing, and Estimating team has worked for the past several years with representatives from MSFC, the local Defense Contract Management Command, and the DCAA to improve the quality of cost proposals to MSFC for contract changes on the SSME. The contract changes on the program result primarily from engineering change proposals for product enhancements to improve safety, maintainability, or operability in the space environment. This continuous improvement team effort has been successful in improving proposal quality, reducing cycle time, and reducing cost. Some of the principal lessons learned are highlighted here to show how proposal improvements can be implemented to enhance customer satisfaction and ensure cost proposals can be evaluated easily by external customers.

    As lithium-ion battery technologies mature, the size and energy of these systems continues to increase (> 50 kWh for EVs); making safety and reliability of these high energy systems increasingly important. While most material advances for lithium-ion chemistries are directed toward improving cell performance (capacity, energy, cycle life, etc.), there are a variety of materials advancements that can be made to improve lithium-ion battery safety. Issues including energetic thermal runaway, electrolyte decomposition and flammability, anode SEI stability, and cell-level abuse tolerance continue to be critical safety concerns. This report highlights work with our collaborators to develop advanced materials to improve lithium-ion battery safety and abuse tolerance and to perform cell-level characterization of new materials.

    Full Text Available Outcomes of cataract surgery are worse than we would like them to be. Community-based studies show that up to 40% of eyes have a postoperative presenting vision of < 6/60. Eyes with intraocular lenses (IOLs do better; however, it has been shown that even in prosperous middle-income countries, such as Venezuela, in 20% of pseudophakic eyes presenting vision was < 6/60 and in 15% best corrected vision was worse than 6/60.Poor outcomes matter. Patients deserve improved vision whenever possible and poor outcomes deter prospective patients from coming for surgery and probably reduce their willingness to pay for their treatment – particularly if they have to pay in advance!In this article, we offer some suggestions for improving the quality of cataract surgery. We admit that there is little evidence base for most of these suggestions and that some of them are controversial. However, we hope to stimulate debate.

In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP. Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR, glaucoma, age-related macular degeneration (ARMD, and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time

  5. Improved flywheel materials :

    Energy Technology Data Exchange (ETDEWEB)

    Boyle, Timothy J.; Bell, Nelson S; Ehlen, Mark Andrew; Anderson, Benjamin John; Miller, William Kenneth


    As alternative energy generating devices (i.e., solar, wind, etc) are added onto the electrical energy grid (AC grid), irregularities in the available electricity due to natural occurrences (i.e., clouds reducing solar input or wind burst increasing wind powered turbines) will be dramatically increased. Due to their almost instantaneous response, modern flywheel-based energy storage devices can act a mechanical mechanism to regulate the AC grid; however, improved spin speeds will be required to meet the necessary energy levels to balance these green energy variances. Focusing on composite flywheels, we have investigated methods for improving the spin speeds based on materials needs. The so-called composite flywheels are composed of carbon fiber (C-fiber), glass fiber, and a glue (resin) to hold them together. For this effort, we have focused on the addition of fillers to the resin in order to improve its properties. Based on the high loads required for standard meso-sized fillers, this project investigated the utility of ceramic nanofillers since they can be added at very low load levels due to their high surface area. The impact that TiO2 nanowires had on the final strength of the flywheel material was determined by a three-point-bend test. The results of the introduction of nanomaterials demonstrated an increase in strength of the flywheels C-fiber-resin moiety, with an upper limit of a 30% increase being reported. An analysis of the economic impact concerning the utilization of the nanowires was undertaken and after accounting for new-technology and additional production costs, return on improved-nanocomposite investment was approximated at 4-6% per year over the 20-year expected service life. Further, it was determined based on the 30% improvement in strength, this change may enable a 20-30% reduction in flywheel energy storage cost ($/kW-h).

    Highlights: • Project to improve the quality of the MDSplus software package. • Use of modern software technology, compiler options, automake. • Refactoring of older code. • Use of testing tools. - Abstract: MDSplus is a data acquisition and analysis system used worldwide predominantly in the fusion research community. Development began 29 years ago on the OpenVMS operating system. Since that time there have been many new features added and the code has been ported to many different operating systems. There have been contributions to the MDSplus development from the fusion community in the way of feature suggestions, feature implementations, documentation and porting to different operating systems. The bulk of the development and support of MDSplus, however, has been provided by a relatively small core developer group of three or four members. Given the size of the development team and the large number of users much more effort was focused on providing new features for the community than on keeping the underlying code and documentation up to date with the evolving software development standards. To ensure that MDSplus will continue to provide the needs of the community in the future, the MDSplus development team along with other members of the MDSplus user community has commenced on a major quality improvement project. The planned improvements include changes to software build scripts to better use GNU Autoconf and Automake tools, refactoring many of the source code modules using new language features available in modern compilers, using GNU MinGW-w64 to create MS Windows distributions, migrating to a more modern source code management system, improvement of source documentation as well as improvements to the ( web site documentation and layout, and the addition of more comprehensive test suites to apply to MDSplus code builds prior to releasing installation kits to the community. This work should lead to a much more robust product and

  7. Mapping soil particle-size fractions using additive-log ratio transformation and proximally sensed ancillary data (United States)

    Zare, Ehsan; Huang, Jingyi; Triantafilis, John


    Together the three particle size fractions (PSFs) of clay, silt, and sand are the most fundamental soil properties because of their relative abundance influences the physical, chemical and biological activities in soil. Therefore, there is an increasing need for high-resolution information on spatial distribution of soil texture. Unfortunately, determining PSFs requires a laboratory method which is time-consuming. One way to add value is to use digital soil mapping. Specifically, using mathematical models, such as multiple linear regression (MLR), to couple ancillary data to PSF data. However, this approach does not account for the special requirements of compositional data. Here we demonstrated how ancillary data can be coupled via MLR modelling to an additive log-ratio transformation (ALR) of the PSF to meet these requirements. We compared these two approaches (MLR vs. ALR-MLR). We also compared the use of different ancillary data including proximally sensed gamma-ray spectrometry (i.e. RS700), electromagnetic induction (i.e. DUALEM-421S) and elevation data. In addition, we tested how prediction might be improved by using ancillary data measured on transects (which simulated measurements made on 6.5 m transects) as compared to interpolation from transects spaced 13 m and 26 m apart. Although the ALR-MLR approach did not produce significantly better results, it generated predicted soil PSFs which summed to 100. We found that for predicting PSFs at various depths, all ancillary data was useful with elevation and gamma-ray slightly better for topsoil and elevation and EM data better for subsoil prediction. In addition, a reduced transect spacing (26 m) and sampling size (9-16) can be adopted for mapping soil PSFs and soil texture across the study field.

    The present invention relates to an improved tool grinding mechanism for grinding single point diamond cutting tools to precise roundness and radius specifications. The present invention utilizes a tool holder which is longitudinally displaced with respect to the remainder of the grinding system due to contact of the tool with the grinding surface with this displacement being monitored so that any variation in the grinding of the cutting surface such as caused by crystal orientation or tool thicknesses may be compensated for during the grinding operation to assure the attainment of the desired cutting tool face specifications.

    For my CERN Summer Student programme I have been working with ATLAS reprocessing group. Data taken at ATLAS experiment is not only processed after being taken, but is also reprocessed multiple times afterwards. This allows applying new alignments, calibration of detector and using improved or faster algorithms. Reprocessing is usually done in campaigns for different periods of data or for different interest groups. The idea of my project was to simplify the definition of tasks and monitoring of their progress. I created a LIST configuration files generator script in Python and a monitoring webpage for tracking current reprocessing tasks.

  16. Improving Departments of Psychology. (United States)

    Diener, Ed


    Our procedures for creating excellent departments of psychology are based largely on selection-hiring and promoting the best people. I argue that these procedures have been successful, but I suggest the implementation of policies that I believe will further improve departments in the behavioral and brain sciences. I recommend that we institute more faculty development programs attached to incentives to guarantee continuing education and scholarly activities after the Ph.D. degree. I also argue that we would do a much better job if we more strongly stream our faculty into research, education, or service and not expect all faculty members to carry equal responsibility for each of these. Finally, I argue that more hiring should occur at advanced levels, where scholars have a proven track record of independent scholarship. Although these practices will be a challenge to implement, institutions do ossify over time and thus searching for ways to improve our departments should be a key element of faculty governance. © The Author(s) 2016.

  19. Design improvement in keratoprosthesis (United States)

    Villain, Franck L.; Lacombe, Emmanuel; Legeais, Jean-Marc; Bos, Gilles; Rol, Pascal O.; Parel, Jean-Marie A.


    One of the major problems of keratoprosthesis (KPro) is postoperative expulsion resulting from inadequate haptic fixation. To overcome this obstacle, a new design was conceived using a retrocorneal fixation. An earlier version of our KPro was made of two pieces: an optical element threaded in a surrounding haptic. Both pieces were made of medical grade PMMA. Although encouraging results were obtained, some anatomic failures occurred (20% at 5 years). To improve fixation and sealing, a biocolonizable skirt was recently added to the keratoprosthesis. This skirt should prevent migration of biocontaminants inside the eye. Made of porous PTFE, the skirt was ultrasonically held inside a one-piece PMMA keratoprosthesis by ultrasonic microwelding. Thus far, implantations carried out in 8 patients show a good tolerance.

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, D.E.; Ohnuma, S.


    MESSYMESH, the MURA program to calculate electromagnetic fields for an Alvarez-type linear accelerating cavity, was revived as an operational program, presently residing on a CDC-6600 computer at Fermilab. It was modified so that one may now start the over-relaxation computations from an analytically derived initial load, instead of the simple Bessel function load which was previously used. The effect of this new loading is to significantly improve the running time for the program and also to allow one to arrive at a truly converged solution to the field quantities for a given mesh size. These two features are of particular interest in calculations associated with low-..beta.. structures, which have previously been quite hard to do with MESSYMESH.

  1. SCET improved SUSY search (United States)

    Liu, Xiaohui; Mantry, Sonny; Petriello, Frank


    Supersymmetry has been one of the most popular candidates for physics beyond standard model (SM) for a long time. The fact that we haven't yet discover super particles in nowadays LHC data, pushes the SUSY production nearer and nearer to the LHC machine threshold. In the threshold limit, how well we understand the SM background is crucial for SUSY or other physics beyond SM search. In this talk, we will use the simplest case by considering photon plus two jets events to address the problem and we will talk about how we use the soft collinear effective theory to sum up potentially large logs related to threshold limit to improve our understanding of the SM background.

    Directory of Open Access Journals (Sweden)

    Kelley O’Reilly


    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

    Transport of people, personal belongings and goods in private cars is fundamental to our modern welfare society and economic growth, and has grown steadily over many decades. Motor fuels have been based almost entirely on crude oil for the last century. During the last couple of decades engines built for traditional fuels have become more advanced and efficient; this has reduced fuel consumption by around 40% and emissions by more than 90%. Only in the same time span have we begun to look at alternatives to fossil fuels. Biofuels such as biodiesel, bioethanol, biomethanol and biogas can replace petrol and diesel, and in recent years algae have shown a new potential for diesel fuel. Natural gas is also becoming an interesting fuel due to its large resources worldwide. GTL, CTL and BTL are liquid fuels produced from solid or gaseous sources. GTL and CTL are expensive to produce and not very CO{sub 2}-friendly, but they are easily introduced and need little investment in infrastructure and vehicles. DME is an excellent fuel for diesel engines. Methanol and DME produced from biomass are among the most CO{sub 2}-reducing fuels and at the same time the most energy-efficient renewable fuels. Fuel cell vehicles (FCVs) are currently fuelled by hydrogen, but other fuels are also possible. There are, however, several barriers to the implementation of fuel cell vehicles. In particular, a hydrogen infrastructure needs to be developed. Electric vehicles (EVs) have the advantage that energy conversion is centralised at the power plant where it can be done at optimum efficiency and emissions. EVs have to be charged at home, and also away from home when travelling longer distances. With an acceptable fast charging infrastructure at least 85% of the one-car families in Denmark could be potential EV customers. Range improvements resulting from better batteries are expected to create a large increase in the number of EVs in Denmark between 2020 and 2030. The hybrid electric vehicle

  7. Regulatory Streamlining and Improvement

    The Interstate Oil and Gas Compact Commission (IOGCC) engaged in numerous projects outlined under the scope of work discussed in the United States Department of Energy (DOE) grant number DE-FC26-04NT15456 awarded to the IOGCC. Numerous projects were completed that were extremely valuable to state oil and gas agencies as a result of work performed utilizing resources provided by the grant. There are numerous areas in which state agencies still need assistance. This additional assistance will need to be addressed under future scopes of work submitted annually to DOE's Project Officer for this grant. This report discusses the progress of the projects outlined under the grant scope of work for the 2005-2006 areas of interest, which are as follows: Area of Interest No. 1--Regulatory Streamlining and Improvement: This area of interest continues to support IOGCC's regulatory streamlining efforts that include the identification and elimination of unnecessary duplications of efforts between and among state and federal programs dealing with exploration and production on public lands. Area of Interest No. 2--Technology: This area of interest seeks to improve efficiency in states through the identification of technologies that can reduce costs. Area of Interest No. 3--Training and Education: This area of interest is vital to upgrading the skills of regulators and industry alike. Within the National Energy Policy, there are many appropriate training and education opportunities. Education was strongly endorsed by the President's National Energy Policy Development group. Acting through the governors offices, states are very effective conduits for the dissemination of energy education information. While the IOGCC favors the development of a comprehensive, long-term energy education plan, states are also supportive of immediate action on important concerns, such as energy prices, availability and conservation.

    Ronald L. Boring; Candice D. Griffith; Jeffrey C. Joe


    The goal of performance shaping factors (PSFs) is to provide measures to account for human performance. PSFs fall into two categories—direct and indirect measures of human performance. While some PSFs such as “time to complete a task” are directly measurable, other PSFs, such as “fitness for duty,” can only be measured indirectly through other measures and PSFs, such as through fatigue measures. This paper explores the role of direct and indirect measures in human reliability analysis (HRA) and the implications that measurement theory has on analyses and applications using PSFs. The paper concludes with suggestions for maximizing the reliability and validity of PSFs.

    El-Eid, Ghada R.; Kaddoum, Roland; Tamim, Hani; Hitti, Eveline A.


    Abstract Delays in discharging patients can impact hospital and emergency department (ED) throughput. The discharge process is complex and involves setting specific challenges that limit generalizability of solutions. The aim of this study was to assess the effectiveness of using Six Sigma methods to improve the patient discharge process. This is a quantitative pre and post-intervention study. Three hundred and eighty-six bed tertiary care hospital. A series of Six Sigma driven interventions over a 10-month period. The primary outcome was discharge time (time from discharge order to patient leaving the room). Secondary outcome measures included percent of patients whose discharge order was written before noon, percent of patients leaving the room by noon, hospital length of stay (LOS), and LOS of admitted ED patients. Discharge time decreased by 22.7% from 2.2 hours during the preintervention period to 1.7 hours post-intervention (P discharge. Hospital LOS dropped from 3.4 to 3.1 days postintervention (P hospital was significantly lower in the postintervention period (6.9 ± 7.8 vs 5.9 ± 7.7 hours; P discharge time. The focus of institutions aspiring to tackle delays in the discharge process should be on adopting the core principles of Six Sigma rather than specific interventions that may be institution-specific.

  10. Improving surgical weekend handover (United States)

    Culwick, Caroline; Devine, Chris; Coombs, Catherine


    Effective handovers are vital to patient safety and continuity of care, and this is recognised by several national bodies including the GMC. The existing model at Great Western Hospital (GWH) involved three general surgical teams and a urology team placing their printed patient lists, complete with weekend jobs, in a folder for the on-call team to collect at the weekend. We recognised a need to reduce time searching for patients, jobs and reviews, and to streamline weekend ward rounds. A unified weekend list ordering all surgical patients by ward and bed number was introduced. Discrepancies in the layout of each team's weekday list necessitated the design of a new weekday list to match the weekend list to facilitate the easy transfer of information between the two lists. A colour coding system was also used to highlight specific jobs. Prior to this improvement project only 7.1% of those polled were satisfied with the existing system, after a series of interventions satisfaction increased to 85.7%. The significant increase in overall satisfaction with surgical handover following the introduction of the unified weekend list is promising. Locating patients and identifying jobs is easier and weekend ward rounds can conducted in a more logical and timely fashion. It has also helped facilitate the transition to consultant ward rounds of all surgical inpatients at the weekends with promising feedback from a recent consultants meeting. PMID:26734294

  11. Improving the urban environment. (United States)

    Rotibi, A


    An effective environmental sanitation program should encompass key features considered necessary for a primary health care (PHC) program such as availability, accessibility, affordability, acceptability, and practicability. Poor housing conditions give rise to stress, delinquency, and crime, as well as to helminthic and other parasitic infestations. In Africa, urbanization has accelerated since the 1950s because of rural-urban migration. In Nigeria new housing construction has been poor, with inadequate provision of physical facilities and community services in residential areas. Overcrowding is rampant, with occupancy rates of 2-3 persons per room recorded for many cities including Owerri, Abba, Warri and Ontisha. In a survey of rooming-house facilities in Lagos, the average was 5-7 persons per room. 47% of households were living in just one rooms in Sokoto and 80% in the Lagos metropolitan area. An urban household survey by the Federal Office of Statistics found that 45% of households were without electricity. Similarly, 46% of households were found to be without running water, 29% obtained their water from wells, and 14% from streams. The inadequate provision of toilets poses major health risks. Many Nigerian cities lack efficient waste disposal systems: in Ibadan mounds of uncollected rubbish obstruct the roads. According to a Statistics Office survey 48% of refuse is estimated to be dumped illegally, while 23% is simply heaped in family compounds. A recently launched campaign on environmental sanitation is the start of improving the health of urban dwellers which could cut expenditure on curative health measures.

    Randall S. Seright


    This report describes work performed during the second year of the project, ''Conformance Improvement Using Gels.'' The project has two objectives. The first objective is to identify gel compositions and conditions that substantially reduce flow through fractures that allow direct channeling between wells, while leaving secondary fractures open so that high fluid injection and production rates can be maintained. The second objective is to optimize treatments in fractured production wells, where the gel must reduce permeability to water much more than that to oil. Pore-level images from X-ray computed microtomography were re-examined for Berea sandstone and porous polyethylene. This analysis suggests that oil penetration through gel-filled pores occurs by a gel-dehydration mechanism, rather than a gel-ripping mechanism. This finding helps to explain why aqueous gels can reduce permeability to water more than to oil. We analyzed a Cr(III)-acetate-HPAM gel treatment in a production well in the Arbuckle formation. The availability of accurate pressure data before, during, and after the treatment was critical for the analysis. After the gel treatment, water productivity was fairly constant at about 20% of the pre-treatment value. However, oil productivity was stimulated by a factor of 18 immediately after the treatment. During the six months after the treatment, oil productivity gradually decreased to approach the pre-treatment value. To explain this behavior, we proposed that the fracture area open to oil flow was increased substantially by the gel treatment, followed by a gradual closing of the fractures during subsequent production. For a conventional Cr(III)-acetate-HPAM gel, the delay between gelant preparation and injection into a fracture impacts the placement, leakoff, and permeability reduction behavior. Formulations placed as partially formed gels showed relatively low pressure gradients during placement, and yet substantially reduced the

    This report describes work performed during the third and final year of the project, ''Conformance Improvement Using Gels.'' Corefloods revealed throughput dependencies of permeability reduction by polymers and gels that were much more prolonged during oil flow than water flow. This behavior was explained using simple mobility ratio arguments. A model was developed that quantitatively fits the results and predicts ''clean up'' times for oil productivity when production wells are returned to service after application of a polymer or gel treatment. X-ray computed microtomography studies of gels in strongly water-wet Berea sandstone and strongly oil-wet porous polyethylene suggested that oil penetration through gel-filled pores occurs by a gel-dehydration mechanism, rather than gel-ripping or gel-displacement mechanisms. In contrast, analysis of data from the University of Kansas suggests that the gel-ripping or displacement mechanisms are more important in more permeable, strongly water-wet sandpacks. These findings help to explain why aqueous gels can reduce permeability to water more than to oil under different conditions. Since cement is the most commonly used material for water shutoff, we considered when gels are preferred over cements. Our analysis and experimental results indicated that cement cannot be expected to completely fill (top to bottom) a vertical fracture of any width, except near the wellbore. For vertical fractures with apertures less than 4 mm, the cement slurry will simply not penetrate very far into the fracture. For vertical fractures with apertures greater than 4 mm, the slurry may penetrate a substantial distance into the bottom part of the fracture. However, except near the wellbore, the upper part of the fracture will remain open due to gravity segregation. We compared various approaches to plugging fractures using gels, including (1) varying polymer content, (2) varying placement (extrusion) rate

  16. Improving clinical cognitive testing (United States)

    Gale, Seth A.; Barrett, A.M.; Boeve, Bradley F.; Chatterjee, Anjan; Coslett, H. Branch; D'Esposito, Mark; Finney, Glen R.; Gitelman, Darren R.; Hart, John J.; Lerner, Alan J.; Meador, Kimford J.; Pietras, Alison C.; Voeller, Kytja S.; Kaufer, Daniel I.


    Objective: To evaluate the evidence basis of single-domain cognitive tests frequently used by behavioral neurologists in an effort to improve the quality of clinical cognitive assessment. Methods: Behavioral Neurology Section members of the American Academy of Neurology were surveyed about how they conduct clinical cognitive testing, with a particular focus on the Neurobehavioral Status Exam (NBSE). In contrast to general screening cognitive tests, an NBSE consists of tests of individual cognitive domains (e.g., memory or language) that provide a more comprehensive diagnostic assessment. Workgroups for each of 5 cognitive domains (attention, executive function, memory, language, and spatial cognition) conducted evidence-based reviews of frequently used tests. Reviews focused on suitability for office-based clinical practice, including test administration time, accessibility of normative data, disease populations studied, and availability in the public domain. Results: Demographic and clinical practice data were obtained from 200 respondents who reported using a wide range of cognitive tests. Based on survey data and ancillary information, between 5 and 15 tests in each cognitive domain were reviewed. Within each domain, several tests are highlighted as being well-suited for an NBSE. Conclusions: We identified frequently used single-domain cognitive tests that are suitable for an NBSE to help make informed choices about clinical cognitive assessment. Some frequently used tests have limited normative data or have not been well-studied in common neurologic disorders. Utilizing standardized cognitive tests, particularly those with normative data based on the individual's age and educational level, can enhance the rigor and utility of clinical cognitive assessment.

  1. Interstate Electrification Improvement Project

    Energy Technology Data Exchange (ETDEWEB)

    Puckette, Margaret [Shorepower Technologies, Hillsboro, OR (United States); Kim, Jeff [Shorepower Technologies, Hillsboro, OR (United States)


    The Interstate Electrification Improvement Project, publicly known as the Shorepower Truck Electrification Project (STEP), started in May 2011 and ended in March 2015. The project grant was awarded by the Department of Energy’s Vehicles Technology Office in the amount of $22.2 million. It had three overarching missions: 1. Reduce the idling of Class 8 tractors when parked at truck stops, to reduce diesel fuel consumption and thus U.S. dependence on foreign petroleum; 2. Stimulate job creation and economic activity as part of the American Reinvestment and Recovery Act of 2009; 3. Reduce greenhouse gas emissions (GHG) from diesel combustion and the carbon footprint of the truck transportation industry. The project design was straightforward. First, build fifty Truck Stop Electrification (TSE) facilities in truck stop parking lots across the country so trucks could plug-in to 110V, 220V, or 480VAC, and shut down the engine instead of idling. These facilities were strategically located at fifty truck stops along major U.S. Interstates with heavy truck traffic. Approximately 1,350 connection points were installed, including 150 high-voltage electric standby Transport Refrigeration Unit (eTRU) plugs--eTRUs are capable of plugging in to shore power1 to cool the refrigerated trailer for loads such as produce, meats and ice cream. Second, the project provided financial incentives on idle reduction equipment to 5,000 trucks in the form of rebates, to install equipment compatible with shore power. This equipment enables drivers to shut down the main engine when parked, to heat or cool their cab, charge batteries, or use other household appliances without idling—a common practice that uses approximately 1 gallon of diesel per hour. The rebate recipients were intended to be the first fleets to plug into Shorepower to save diesel fuel and ensure there is significant population of shore power capable trucks. This two part project was designed to complement each other by

    Vizcaino, I.; Costa, S.; Cremades, A. [Hospital Universitario Dr. Peset. Valencia (Spain)


    Musculoaponeurotic fibromatosis is a well-differentiated benign tumoral condition of fibroblastic origin that is classified as a tumor of the soft tissue. These lesions present an intermediate biological behavior between the benign fibroblastic tumors and fibrosarcoma, and have the capacity of presenting local relapse, but never metastasis. One case of post-traumatic musculoaponeurotic fibromatosis of the scalene muscle is presented by the study of the ultrasonography, CT and MRI. The imaging findings are not characteristics, but they are useful to carry out the differential diagnosis and extension study. (Author) 14 refs.

  19. Improving a Dental School's Clinic Operations Using Lean Process Improvement. (United States)

    Robinson, Fonda G; Cunningham, Larry L; Turner, Sharon P; Lindroth, John; Ray, Deborah; Khan, Talib; Yates, Audrey


    The term "lean production," also known as "Lean," describes a process of operations management pioneered at the Toyota Motor Company that contributed significantly to the success of the company. Although developed by Toyota, the Lean process has been implemented at many other organizations, including those in health care, and should be considered by dental schools in evaluating their clinical operations. Lean combines engineering principles with operations management and improvement tools to optimize business and operating processes. One of the core concepts is relentless elimination of waste (non-value-added components of a process). Another key concept is utilization of individuals closest to the actual work to analyze and improve the process. When the medical center of the University of Kentucky adopted the Lean process for improving clinical operations, members of the College of Dentistry trained in the process applied the techniques to improve inefficient operations at the Walk-In Dental Clinic. The purpose of this project was to reduce patients' average in-the-door-to-out-the-door time from over four hours to three hours within 90 days. Achievement of this goal was realized by streamlining patient flow and strategically relocating key phases of the process. This initiative resulted in patient benefits such as shortening average in-the-door-to-out-the-door time by over an hour, improving satisfaction by 21%, and reducing negative comments by 24%, as well as providing opportunity to implement the electronic health record, improving teamwork, and enhancing educational experiences for students. These benefits were achieved while maintaining high-quality patient care with zero adverse outcomes during and two years following the process improvement project.

  6. Strategies to improve running economy. (United States)

    Barnes, Kyle R; Kilding, Andrew E


    Running economy (RE) represents a complex interplay of physiological and biomechanical factors that is typically defined as the energy demand for a given velocity of submaximal running and expressed as the submaximal oxygen uptake (VO2) at a given running velocity. This review considered a wide range of acute and chronic interventions that have been investigated with respect to improving economy by augmenting one or more components of the metabolic, cardiorespiratory, biomechanical or neuromuscular systems. Improvements in RE have traditionally been achieved through endurance training. Endurance training in runners leads to a wide range of physiological responses, and it is very likely that these characteristics of running training will influence RE. Training history and training volume have been suggested to be important factors in improving RE, while uphill and level-ground high-intensity interval training represent frequently prescribed forms of training that may elicit further enhancements in economy. More recently, research has demonstrated short-term resistance and plyometric training has resulted in enhanced RE. This improvement in RE has been hypothesized to be a result of enhanced neuromuscular characteristics. Altitude acclimatization results in both central and peripheral adaptations that improve oxygen delivery and utilization, mechanisms that potentially could improve RE. Other strategies, such as stretching should not be discounted as a training modality in order to prevent injuries; however, it appears that there is an optimal degree of flexibility and stiffness required to maximize RE. Several nutritional interventions have also received attention for their effects on reducing oxygen demand during exercise, most notably dietary nitrates and caffeine. It is clear that a range of training and passive interventions may improve RE, and researchers should concentrate their investigative efforts on more fully understanding the types and mechanisms that

  8. Improving efficiency in meat production. (United States)

    Brameld, John M; Parr, Tim


    Selective breeding and improved nutritional management over the past 20-30 years has resulted in dramatic improvements in growth efficiency for pigs and poultry, particularly lean tissue growth. However, this has been achieved using high-quality feed ingredients, such as wheat and soya that are also used for human consumption and more recently biofuels production. Ruminants on the other hand are less efficient, but are normally fed poorer quality ingredients that cannot be digested by human subjects, such as grass or silage. The challenges therefore are to: (i) maintain the current efficiency of growth of pigs and poultry, but using more ingredients not needed to feed the increasing human population or for the production of biofuels; (ii) improve the efficiency of growth in ruminants; (iii) at the same time produce animal products (meat, milk and eggs) of equal or improved quality. This review will describe the use of: (a) enzyme additives for animal feeds, to improve feed digestibility; (b) known growth promoting agents, such as growth hormone, β-agonists and anabolic steroids, currently banned in the European Union but used in other parts of the world; (c) recent transcriptomic studies into molecular mechanisms for improved growth efficiency via low residual feed intake. In doing so, the use of genetic manipulation in animals will also be discussed.

  9. Improvability of assembly systems II: Improvability indicators and case study

    Directory of Open Access Journals (Sweden)

    S.-Y. Chiang


    Full Text Available Based on the performance analysis technique developed in Part I, this paper presents improvability indicators for assembly lines with unreliable machines. In particular, it shows that assembly lines are unimprovable with respect to workforce re-distribution if each buffer is, on the average, close to being half full. These lines are unimprovable with respect to buffer capacity re-distribution if each machine is starved and blocked with almost equal frequency. In addition, the paper provides indicators for identification of bottleneck machines and bottleneck buffers. Finally, the paper reports on an application of these improvability indicators in a case study at an automotive components plant.

  10. Characterization and modelling of the spatially- and spectrally-varying point-spread function in hyperspectral imaging systems for computational correction of axial optical aberrations (United States)

    Špiclin, Žiga; Bürmen, Miran; Pernuš, Franjo; Likar, Boštjan


    Spatial resolution of hyperspectral imaging systems can vary significantly due to axial optical aberrations that originate from wavelength-induced index-of-refraction variations of the imaging optics. For systems that have a broad spectral range, the spatial resolution will vary significantly both with respect to the acquisition wavelength and with respect to the spatial position within each spectral image. Variations of the spatial resolution can be effectively characterized as part of the calibration procedure by a local image-based estimation of the pointspread function (PSF) of the hyperspectral imaging system. The estimated PSF can then be used in the image deconvolution methods to improve the spatial resolution of the spectral images. We estimated the PSFs from the spectral images of a line grid geometric caliber. From individual line segments of the line grid, the PSF was obtained by a non-parametric estimation procedure that used an orthogonal series representation of the PSF. By using the non-parametric estimation procedure, the PSFs were estimated at different spatial positions and at different wavelengths. The variations of the spatial resolution were characterized by the radius and the fullwidth half-maximum of each PSF and by the modulation transfer function, computed from images of USAF1951 resolution target. The estimation and characterization of the PSFs and the image deconvolution based spatial resolution enhancement were tested on images obtained by a hyperspectral imaging system with an acousto-optic tunable filter in the visible spectral range. The results demonstrate that the spatial resolution of the acquired spectral images can be significantly improved using the estimated PSFs and image deconvolution methods.

  12. Blind deconvolution with principal components analysis for wide-field and small-aperture telescopes (United States)

    Jia, Peng; Sun, Rongyu; Wang, Weinan; Cai, Dongmei; Liu, Huigen


    Telescopes with a wide field of view (greater than 1°) and small apertures (less than 2 m) are workhorses for observations such as sky surveys and fast-moving object detection, and play an important role in time-domain astronomy. However, images captured by these telescopes are contaminated by optical system aberrations, atmospheric turbulence, tracking errors and wind shear. To increase the quality of images and maximize their scientific output, we propose a new blind deconvolution algorithm based on statistical properties of the point spread functions (PSFs) of these telescopes. In this new algorithm, we first construct the PSF feature space through principal component analysis, and then classify PSFs from a different position and time using a self-organizing map. According to the classification results, we divide images of the same PSF types and select these PSFs to construct a prior PSF. The prior PSF is then used to restore these images. To investigate the improvement that this algorithm provides for data reduction, we process images of space debris captured by our small-aperture wide-field telescopes. Comparing the reduced results of the original images and the images processed with the standard Richardson-Lucy method, our method shows a promising improvement in astrometry accuracy.

  13. Biotechnological advancements in alfalfa improvement. (United States)

    Kumar, Suresh


    Review of biotechnology research in alfalfa shows that molecular techniques are extensively being used for basic and applied research toward alfalfa improvement. Biotechnological approaches have been used in two major areas, genomics and transgenics. In genomics, molecular markers, structural and functional genomics allowed identification of genes of interest and their regulatory components. Alfalfa being obstinate to genetic and genomic analysis, comparative genomics is used for molecular and genetic dissection of various plant processes in alfalfa. Alternatively, transgenic approach involves incorporation of specific and useful genes into alfalfa to improve the traits of interest. Input traits to improve agronomic performance and output traits to improve forage quality, or to produce novel industrial/pharmaceutical proteins, are the focus of current transgenic research in alfalfa. However, transgenic approach is controversial requiring cautious experimental design to combat bioisafety concerns. Ideally, forage alfalfa needs to possess more fermentable carbohydrates, proteins with balanced amino acid profile that degrade slower in rumen, improved winter hardiness, better water use efficiency, pest resistance and no anti-quality factors. Concerted efforts are required to bring together maximum of these characteristic features into the alfalfa plant.

  14. Global quality imaging: improvement actions. (United States)

    Lau, Lawrence S; Pérez, Maria R; Applegate, Kimberly E; Rehani, Madan M; Ringertz, Hans G; George, Robert


    Workforce shortage, workload increase, workplace changes, and budget challenges are emerging issues around the world, which could place quality imaging at risk. It is important for imaging stakeholders to collaborate, ensure patient safety, improve the quality of care, and address these issues. There is no single panacea. A range of improvement measures, strategies, and actions are required. Examples of improvement actions supporting the 3 quality measures are described under 5 strategies: conducting research, promoting awareness, providing education and training, strengthening infrastructure, and implementing policies. The challenge is to develop long-term, cost-effective, system-based improvement actions that will bring better outcomes and underpin a sustainable future for quality imaging. In an imaging practice, these actions will result in selecting the right procedure (justification), using the right dose (optimization), and preventing errors along the patient journey. To realize this vision and implement these improvement actions, a range of expertise and adequate resources are required. Stakeholders should collaborate and work together. In today's globalized environment, collaboration is strength and provides synergy to achieve better outcomes and greater success. Copyright © 2011 American College of Radiology.

  15. Cadastral Database Positional Accuracy Improvement (United States)

    Hashim, N. M.; Omar, A. H.; Ramli, S. N. M.; Omar, K. M.; Din, N.


    Positional Accuracy Improvement (PAI) is the refining process of the geometry feature in a geospatial dataset to improve its actual position. This actual position relates to the absolute position in specific coordinate system and the relation to the neighborhood features. With the growth of spatial based technology especially Geographical Information System (GIS) and Global Navigation Satellite System (GNSS), the PAI campaign is inevitable especially to the legacy cadastral database. Integration of legacy dataset and higher accuracy dataset like GNSS observation is a potential solution for improving the legacy dataset. However, by merely integrating both datasets will lead to a distortion of the relative geometry. The improved dataset should be further treated to minimize inherent errors and fitting to the new accurate dataset. The main focus of this study is to describe a method of angular based Least Square Adjustment (LSA) for PAI process of legacy dataset. The existing high accuracy dataset known as National Digital Cadastral Database (NDCDB) is then used as bench mark to validate the results. It was found that the propose technique is highly possible for positional accuracy improvement of legacy spatial datasets.

  16. Distributed Video Coding: Iterative Improvements

    DEFF Research Database (Denmark)

    Luong, Huynh Van

    at the decoder side offering such benefits for these applications. Although there have been some advanced improvement techniques, improving the DVC coding efficiency is still challenging. The thesis addresses this challenge by proposing several iterative algorithms at different working levels, e.g. bitplane......, band, and frame levels. In order to show the information theoretic basis, theoretical foundations of DVC are introduced. The first proposed algorithm applies parallel iterative decoding using multiple LDPC decoders to utilize cross bitplane correlation. To improve Side Information (SI) generation...... and noise modeling and also learn from the previous decoded Wyner-Ziv (WZ) frames, side information and noise learning (SING) is proposed. The SING scheme introduces an optical flow technique to compensate the weaknesses of the block based SI generation and also utilizes clustering of DCT blocks to capture...

    Allen, Alice; DuPrie, Kimberly; Mink, Jessica; Nemiroff, Robert; Robitaille, Thomas; Shamir, Lior; Shortridge, Keith; Taylor, Mark; Teuben, Peter; Wallin, John


    The past year has seen movement on several fronts for improving software citation, including the Center for Open Science's Transparency and Openness Promotion (TOP) Guidelines, the Software Publishing Special Interest Group that was started at January's AAS meeting in Seattle at the request of that organization's Working Group on Astronomical Software, a Sloan-sponsored meeting at GitHub in San Francisco to begin work on a cohesive research software citation-enabling platform, the work of Force11 to "transform and improve" research communication, and WSSSPE's ongoing efforts that include software publication, citation, credit, and sustainability. Brief reports on these efforts were shared at the BoF, after which participants discussed ideas for improving software citation, generating a list of recommendations to the community of software authors, journal publishers, ADS, and research authors. The discussion, recommendations, and feedback will help form recommendations for software citation to those publishers...

  18. Baseline budgeting for continuous improvement. (United States)

    Kilty, G L


    This article is designed to introduce the techniques used to convert traditionally maintained department budgets to baseline budgets. This entails identifying key activities, evaluating for value-added, and implementing continuous improvement opportunities. Baseline Budgeting for Continuous Improvement was created as a result of a newly named company president's request to implement zero-based budgeting. The president was frustrated with the mind-set of the organization, namely, "Next year's budget should be 10 to 15 percent more than this year's spending." Zero-based budgeting was not the answer, but combining the principles of activity-based costing and the Just-in-Time philosophy of eliminating waste and continuous improvement did provide a solution to the problem.

  19. Eating soya improves human memory. (United States)

    File, S E; Jarrett, N; Fluck, E; Duffy, R; Casey, K; Wiseman, H


    Soya foods are rich in isoflavone phytoestrogens with weak agonist activity at oestrogen receptors. Oestrogen treatment has been found to improve memory in men awaiting gender reassignment and in post-menopausal women. To examine the effects of supervised high versus low soya diets on attention, memory and frontal lobe function in young healthy adults of both sexes. Student volunteers were randomly allocated to receive, under supervision, a high soya (100 mg total isoflavones/day) or a low soya (0.5 mg total isoflavones/day) diet for 10 weeks. They received a battery of cognitive tests at baseline and then after 10 weeks of diet. Those receiving the high soya diet showed significant improvements in short-term (immediate recall of prose and 4-s delayed matching to sample of patterns) and long-term memory (picture recall after 20 min) and in mental flexibility (rule shifting and reversal). These improvements were found in males and females. In a letter fluency test and in a test of planning (Stockings of Cambridge), the high soya diet improved performance only in females. There was no effect of diet on tests of attention or in a category generation task. Those on the high soya diet rated themselves as more restrained and, after the tests of memory and attention, they became less tense than did those on the control diet. Significant cognitive improvements can arise from a relatively brief dietary intervention, and the improvements from a high soya diet are not restricted to women or to verbal tasks.

  20. Motor Activity Improves Temporal Expectancy (United States)

    Fautrelle, Lilian; Mareschal, Denis; French, Robert; Addyman, Caspar; Thomas, Elizabeth


    Certain brain areas involved in interval timing are also important in motor activity. This raises the possibility that motor activity might influence interval timing. To test this hypothesis, we assessed interval timing in healthy adults following different types of training. The pre- and post-training tasks consisted of a button press in response to the presentation of a rhythmic visual stimulus. Alterations in temporal expectancy were evaluated by measuring response times. Training consisted of responding to the visual presentation of regularly appearing stimuli by either: (1) pointing with a whole-body movement, (2) pointing only with the arm, (3) imagining pointing with a whole-body movement, (4) simply watching the stimulus presentation, (5) pointing with a whole-body movement in response to a target that appeared at irregular intervals (6) reading a newspaper. Participants performing a motor activity in response to the regular target showed significant improvements in judgment times compared to individuals with no associated motor activity. Individuals who only imagined pointing with a whole-body movement also showed significant improvements. No improvements were observed in the group that trained with a motor response to an irregular stimulus, hence eliminating the explanation that the improved temporal expectations of the other motor training groups was purely due to an improved motor capacity to press the response button. All groups performed a secondary task equally well, hence indicating that our results could not simply be attributed to differences in attention between the groups. Our results show that motor activity, even when it does not play a causal or corrective role, can lead to improved interval timing judgments. PMID:25806813

  1. Using Simulation to Improve Systems. (United States)

    Kearney, James A; Deutsch, Ellen S


    Attempts to understand and improve health care delivery often focus on the characteristics of the patient and the characteristics of the health care providers, but larger systems surround and integrate with patients and providers. Components of health care delivery systems can support or interfere with efforts to provide optimal health care. Simulation in situ, involving real teams participating in simulations in real care settings, can be used to identify latent safety threats and improve the work environment while simultaneously supporting participant learning. Thoughtful planning and skilled debriefing are essential. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hill, Gary C.


    Designer and design team productivity improves with skill, experience, and the tools available. The design process involves numerous trials and errors, analyses, refinements, and addition of details. Computerized tools have greatly speeded the analysis, and now new theories and methods, emerging under the label Artificial Intelligence (AI), are being used to automate skill and experience. These tools improve designer productivity by capturing experience, emulating recognized skillful designers, and making the essence of complex programs easier to grasp. This paper outlines the aircraft design process in today's technology and business climate, presenting some of the challenges ahead and some of the promising AI methods for meeting these challenges.

  6. Improving quality of care through improved audit and feedback

    Directory of Open Access Journals (Sweden)

    Hysong Sylvia J


    Full Text Available Abstract Background The Department of Veterans Affairs (VA has led the industry in measuring facility performance as a critical element in improving quality of care, investing substantial resources to develop and maintain valid and cost-effective measures. The External Peer Review Program (EPRP of the VA is the official data source for monitoring facility performance, used to prioritize the quality areas needing most attention. Facility performance measurement has significantly improved preventive and chronic care, as well as overall quality; however, much variability still exists in levels of performance across measures and facilities. Audit and feedback (A&F, an important component of effective performance measurement, can help reduce this variability and improve overall performance. Previous research suggests that VA Medical Centers (VAMCs with high EPRP performance scores tend to use EPRP data as a feedback source. However, the manner in which EPRP data are used as a feedback source by individual providers as well as service line, facility, and network leadership is not well understood. An in-depth understanding of mental models, strategies, and specific feedback process characteristics adopted by high-performing facilities is thus urgently needed. This research compares how leaders of high, low, and moderately performing VAMCs use clinical performance data from the EPRP as a feedback tool to maintain and improve quality of care. Methods We will conduct a qualitative, grounded theory analysis of up to 64 interviews using a novel method of sampling primary care, facility, and Veterans Integrated Service Network (VISN leadership at high-, moderate-, and low-performing facilities. We will analyze interviews for evidence of cross-facility differences in perceptions of performance data usefulness and strategies for disseminating performance data evaluating performance, with particular attention to timeliness, individualization, and punitiveness

  11. [Financial incentives for quality improvement]. (United States)

    Belicza, Eva; Evetovits, Tamás


    Policy makers and payers of health care services devote increasing attention to improve quality of services by incentivising health care providers. These--so called--pay for performance (P4P) programmes have so far been introduced in few countries only and evidence on their effectiveness is still scarce. Therefore we do not know yet which instruments of these programmes are most effective and efficient in improving quality. The P4P systems implemented so far in primary care and in integrated delivery systems use indicators for measurement of performance and the basis for rewards. These indicators are mostly process indicators, but there are some outcome indicators as well. The desired quality improvement effects are most likely to be achieved with programmes that provide seizable financial rewards and cover the extra cost of quality improvement efforts as well. Administration of the programme has to be fully transparent and clear to all involved. It has to be based on scientific evidence and supported with sufficient dedicated funding. Conducting pilot studies is a precondition for large scale implementation.

  15. Piloting improved cookstoves in India. (United States)

    Lewis, Jessica J; Bhojvaid, Vasundhara; Brooks, Nina; Das, Ipsita; Jeuland, Marc A; Patange, Omkar; Pattanayak, Subhrendu K


    Despite the potential of improved cookstoves to reduce the adverse environmental and health impacts of solid fuel use, their adoption and use remains low. Social marketing-with its focus on the marketing mix of promotion, product, price, and place-offers a useful way to understand household behaviors and design campaigns to change biomass fuel use. We report on a series of pilots across 3 Indian states that use different combinations of the marketing mix. We find sales varying from 0% to 60%. Behavior change promotion that combined door-to-door personalized demonstrations with information pamphlets was effective. When given a choice amongst products, households strongly preferred an electric stove over improved biomass-burning options. Among different stove attributes, reduced cooking time was considered most valuable by those adopting a new stove. Households clearly identified price as a significant barrier to adoption, while provision of discounts (e.g., rebates given if households used the stove) or payments in installments were related to higher purchase. Place-based factors such as remoteness and nongovernmental organization operations significantly affected the ability to supply and convince households to buy and use improved cookstoves. Collectively, these pilots point to the importance of continued and extensive testing of messages, pricing models, and different stove types before scale-up. Thus, we caution that a one-size-fits-all approach will not boost improved cookstove adoption.

  6. Clinical engagement: improving healthcare together. (United States)

    Riches, E; Robson, B


    Clinical engagement can achieve lasting change in the delivery of healthcare. In October 2011, Healthcare Improvement Scotland formulated a clinical engagement strategy to ensure that a progressive and sustainable approach to engaging healthcare professionals is firmly embedded in its health improvement and public assurance activities. The strategy was developed using a 90-day process, combining an evidence base of best practice and feedback from semi-structured interviews and focus groups. The strategy aims to create a culture where clinicians view working with Healthcare Improvement Scotland as a worthwhile venture, which offers a number of positive benefits such as training, career development and research opportunities. The strategy works towards developing a respectful partnership between Healthcare Improvement Scotland, the clinical community and key stakeholders whereby clinicians' contributions are recognised in a non-financial reward system. To do this, the organisation needs a sustainable infrastructure and an efficient, cost-effective approach to clinical engagement. There are a number of obstacles to achieving successful clinical engagement and these must be addressed as key drivers in its implementation. The implementation of the strategy is supported by an action and resource plan, and its impact will be monitored by a measurement plan to ensure the organisation reviews its approaches towards clinical engagement.

  12. Improving Patient Acceptance of Insulin Therapy by Improving Needle Design (United States)

    Norman, James J.; Prausnitz, Mark R.


    Improved needle designs could increase patient compliance with insulin therapy. In this issue of Journal of Diabetes Science and Technology, Hirsch and colleagues assessed patient pain and preference for a 5-bevel needle design among diabetes patients. A blinded comparison with traditional 3-bevel needles yielded no significant difference, but patients preferred the 5-bevel needle in unblinded home injection and clinical insertion studies. This suggests that important subjective/contextual factors contribute to preference in conjunction with the fundamental needle design change. While 5-bevel needles may increase patient acceptance, more dramatic changes of needle design, such as microneedles, could enable still greater patient acceptance through reduced pain as well as improved insulin pharmacokinetics. PMID:22538143

  15. Science-based HRA: experimental comparison of operator performance to IDAC (Information-Decision-Action Crew) simulations

    Shirley, Rachel [The Ohio State Univ., Columbus, OH (United States); Smidts, Carol [The Ohio State Univ., Columbus, OH (United States); Boring, Ronald [Idaho National Lab. (INL), Idaho Falls, ID (United States); Li, Yuandan [Univ. of Maryland, College Park, MD (United States); Mosleh, Ali [Univ. of Maryland, College Park, MD (United States)


    Information-Decision-Action Crew (IDAC) operator model simulations of a Steam Generator Tube Rupture are compared to student operator performance in studies conducted in the Ohio State University’s Nuclear Power Plant Simulator Facility. This study is presented as a prototype for conducting simulator studies to validate key aspects of Human Reliability Analysis (HRA) methods. Seven student operator crews are compared to simulation results for crews designed to demonstrate three different decision-making strategies. The IDAC model used in the simulations is modified slightly to capture novice behavior rather that expert operators. Operator actions and scenario pacing are compared. A preliminary review of available performance shaping factors (PSFs) is presented. After the scenario in the NPP Simulator Facility, student operators review a video of the scenario and evaluate six PSFs at pre-determined points in the scenario. This provides a dynamic record of the PSFs experienced by the OSU student operators. In this preliminary analysis, Time Constraint Load (TCL) calculated in the IDAC simulations is compared to TCL reported by student operators. We identify potential modifications to the IDAC model to develop an “IDAC Student Operator Model.” This analysis provides insights into how similar experiments could be conducted using expert operators to improve the fidelity of IDAC simulations.

  16. Improved power performance assessment methods

    Frandsen, S.; Antoniou, I.; Dahlberg, J.A. [and others


    The uncertainty of presently-used methods for retrospective assessment of the productive capacity of wind farms is unacceptably large. The possibilities of improving the accuracy have been investigated and are reported. A method is presented that includes an extended power curve and site calibration. In addition, blockage effects with respect to reference wind speed measurements are analysed. It is found that significant accuracy improvements are possible by the introduction of more input variables such as turbulence and wind shear, in addition to mean wind speed and air density. Also, the testing of several or all machines in the wind farm - instead of only one or two - may provide a better estimate of the average performance. (au)

  17. On Improvements of Cyclic MUSIC

    Directory of Open Access Journals (Sweden)

    H. Howard Fan


    Full Text Available Many man-made signals encountered in communications exhibit cyclostationarity. By exploiting cyclostationarity, cyclic MUSIC has been shown to be able to separate signals with different cycle frequencies, thus, to be able to perform signal selective direction of-arrival (DOA estimation. However, as will be shown in this paper, the DOA estimation of cyclic MUSIC is actually biased. We show in this paper that by properly choosing the frequency for evaluating the steering vector, the bias of DOA estimation can be substantially reduced and the performance can be improved. Furthermore, we propose another algorithm exploiting cyclic conjugate correlation to further improve the performance of DOA estimation. Simulation results show the effectiveness of both of our methods.

  18. Bitumen nanocomposites with improved performance

    KAUST Repository

    Kosma, Vasiliki


    Bitumen-clay nanocomposite binders with styrene-butadienestyrene triblock copolymer, SBS, and combinations of SBS and crumb rubber (CR) with different CR/SBS ratios have been synthesized and characterized. In addition to the binder, samples containing the binder and concrete sand (with a weight ratio 1:9) were prepared. The modified binders were studied in terms of filler dispersion, storage stability, mechanical performance and water susceptibility. We demonstrate that the samples containing nanoclays consistently outperform those based only on the polymer additives. We also find that nanocomposite samples based on a combination of SBS and CR are best, since in addition to other improvements they show excellent storage stability. Our work shows that substituting CR with SBS as a bitumen additive and combining it with inexpensive nanoclays leads to new materials with enhanced performance and improved stability for practical asphalt applications.

  19. Group discussion improves lie detection. (United States)

    Klein, Nadav; Epley, Nicholas


    Groups of individuals can sometimes make more accurate judgments than the average individual could make alone. We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

  20. An Improved Refractive Focusing Optic

    Energy Technology Data Exchange (ETDEWEB)

    Tabeling, Joseph [Delaware Diamond Knives, Inc., Wilmington, DE (United States)


    A diamond optic that can both dissipate the heat load while reducing phase profile errors of the beam will allow a more full realization of the benefits of the previous investments in light sources by allowing experiments that depend on high resolution imaging or spacial resolution. Reducing the x-ray spot size on samples will improve the quality of this information leading to better understanding of materials properties. During Phase I, we explored techniques for characterizing and improving the accuracy of the shape of diamond lenses, particularly in the apex of the parabolic curve, in order to make an optic whose optical performance exceeds what is currently available. We made efforts to reduce the lens surface roughness through a variety of dry etching methods. Additional work sought to make compound lenses with shorter focal lengths and to mount the lenses on copper supports by a variety of methods. Lastly, lenses were made and tested on the 1-BM beamline at APS.

  10. Improving Peptide Applications Using Nanotechnology. (United States)

    Narayanaswamy, Radhika; Wang, Tao; Torchilin, Vladimir P


    Peptides are being successfully used in various fields including therapy and drug delivery. With advancement in nanotechnology and targeted delivery carrier systems, suitable modification of peptides has enabled achievement of many desirable goals over-riding some of the major disadvantages associated with the delivery of peptides in vivo. Conjugation or physical encapsulation of peptides to various nanocarriers, such as liposomes, micelles and solid-lipid nanoparticles, has improved their in vivo performance multi-fold. The amenability of peptides to modification in chemistry and functionalization with suitable nanocarriers are very relevant aspects in their use and have led to the use of 'smart' nanoparticles with suitable linker chemistries that favor peptide targeting or release at the desired sites, minimizing off-target effects. This review focuses on how nanotechnology has been used to improve the number of peptide applications. The paper also focuses on the chemistry behind peptide conjugation to nanocarriers, the commonly employed linker chemistries and the several improvements that have already been achieved in the areas of peptide use with the help of nanotechnology.

  11. Improving immunization approaches to cholera. (United States)

    Saha, Amit; Rosewell, Alexander; Hayen, Andrew; MacIntyre, C Raina; Qadri, Firdausi


    Cholera's impact is greatest in resource-limited countries. In the last decade several large epidemics have led to a global push to improve and implement the tools for cholera prevention and control. Areas covered: PubMed, Google Scholar and the WHO website were searched to review the literature and summarize the current status of cholera vaccines to make recommendations on improving immunization approaches to cholera. Oral cholera vaccines (OCVs) have demonstrated their effectiveness in endemic, outbreak response and emergency settings, highlighting their potential for wider adoption. While two doses of the currently available OCVs are recommended by manufacturers, a single dose would be easier to implement. Encouragingly, recent studies have shown that cold chain requirements may no longer be essential. The establishment of the global OCV stockpile in 2013 has been a major advance in cholera preparedness. New killed and live-attenuated vaccines are being actively explored as candidate vaccines for endemic settings and/or as a traveller's vaccine. The recent advances in cholera vaccination approaches should be considered in the global cholera control strategy. Expert commentary: The development of affordable cholera vaccines is a major success to improve cholera control. New vaccines and country specific interventions will further reduce the burden of this disease globally.

  12. Bioreactor control improves bioprocess performance. (United States)

    Simutis, Rimvydas; Lübbert, Andreas


    The performance of bioreactors is not only determined by productivity but also by process quality, which is mainly determined by variances in the process variables. As fluctuations in these quantities directly affect the variability in the product properties, combatting distortions is the main task of practical quality assurance. The straightforward way of reducing this variability is keeping the product formation process tightly under control. Purpose of this keynote is to show that there is enough evidence in literature showing that the performance of the fermentation processes can significantly be improved by feedback control. Most of the currently used open loop control procedures can be replaced by relatively simple feedback techniques. It is shown by practical examples that such a retrofitting does not require significant changes in the well-established equipment. Feedback techniques are best in assuring high reproducibility of the industrial cultivation processes and thus in assuring the quality of their products. Many developments in supervising and controlling industrial fermentations can directly be taken over in manufacturing processes. Even simple feedback controllers can efficiently improve the product quality. It's the time now that manufacturers follow the developments in most other industries and improve process quality by automatic feedback control. Copyright © 2015 WILEY-VCH Verlag GmbH & Co.

  13. Improved Cloud Condensation Nucleus Spectrometer (United States)

    Leu, Ming-Taun


    An improved thermal-gradient cloud condensation nucleus spectrometer (CCNS) has been designed to provide several enhancements over prior thermal- gradient counters, including fast response and high-sensitivity detection covering a wide range of supersaturations. CCNSs are used in laboratory research on the relationships among aerosols, supersaturation of air, and the formation of clouds. The operational characteristics of prior counters are such that it takes long times to determine aerosol critical supersaturations. Hence, there is a need for a CCNS capable of rapid scanning through a wide range of supersaturations. The present improved CCNS satisfies this need. The improved thermal-gradient CCNS (see Figure 1) incorporates the following notable features: a) The main chamber is bounded on the top and bottom by parallel thick copper plates, which are joined by a thermally conductive vertical wall on one side and a thermally nonconductive wall on the opposite side. b) To establish a temperature gradient needed to establish a supersaturation gradient, water at two different regulated temperatures is pumped through tubes along the edges of the copper plates at the thermally-nonconductive-wall side. Figure 2 presents an example of temperature and supersaturation gradients for one combination of regulated temperatures at the thermally-nonconductive-wall edges of the copper plates. c) To enable measurement of the temperature gradient, ten thermocouples are cemented to the external surfaces of the copper plates (five on the top plate and five on the bottom plate), spaced at equal intervals along the width axis of the main chamber near the outlet end. d) Pieces of filter paper or cotton felt are cemented onto the interior surfaces of the copper plates and, prior to each experimental run, are saturated with water to establish a supersaturation field inside the main chamber. e) A flow of monodisperse aerosol and a dilution flow of humid air are introduced into the main

  14. Toyota production system quality improvement initiative improves perioperative antibiotic therapy. (United States)

    To assess the role of a Toyota production system (TPS) quality improvement (QI) intervention on appropriateness of perioperative antibiotic therapy and in length of hospital stay (LOS) among surgical patients. Pre-post quasi-experimental study using local and national retrospective cohorts. We used TPS methods to implement a multifaceted intervention to reduce nosocomial methicillin-resistant Staphylococcus aureus infections on a Veterans Affairs surgical unit, which led to a QI intervention targeting appropriate perioperative antibiotic prophylaxis. Appropriate perioperative antibiotic therapy was defined as selection of the recommended antibiotic agents for a duration not exceeding 24 hours from the time of the operation. The local computerized medical record system was used to identify patients undergoing the 25 most common surgical procedures and to examine changes in appropriate antibiotic therapy and LOS over time. Overall, 2550 surgical admissions were identified from the local computerized medical records. The proportion of surgical admissions receiving appropriate perioperative antibiotics was significantly higher (P <.01) in 2004 after initiation of the TPS intervention (44.0%) compared with the previous 4 years (range, 23.4%-29.8%) primarily because of improvements in compliance with antibiotic therapy duration rather than appropriate antibiotic selection. There was no statistically significant decrease in LOS over time. The use of TPS methods resulted in a QI intervention that was associated with an increase in appropriate perioperative antibiotic therapy among surgical patients, without affecting LOS.

  15. Improved Biomass Cooking Stoves and Improved Stove Emission Equipment

    Energy Technology Data Exchange (ETDEWEB)

    HATFIELD, MICHAEL; Still, Dean


    In developing countries, there is an urgent need for access to safe, efficient, and more affordable cooking technologies. Nearly 2.5 billion people currently use an open fire or traditional cookstove to prepare their meals, and recent models predict that use of biomass for cooking will continue to be the dominant energy use in rural, resource-poor households through 2030. For these families, cooking poses serious risks to health, safety, and income. An alarming 4 million people, primarily women and children, die prematurely each year from indoor and outdoor exposure to the harmful emissions released by solid fuel combustion. Use of traditional stoves can also have a significant impact on deforestation and climate change. This dire situation creates a critical need for cookstoves that significantly and verifiably reduce fuel use and emissions in order to reach protective levels for human health and the environment. Additionally, advances in the scientific equipment needed to measure and monitor stove fuel use and emissions have not kept pace with the significant need within the industry. While several testing centers in the developed world may have hundred thousand-dollar emissions testing systems, organizations in the field have had little more than a thermometer, a scale, and subjective observations to quantify the performance of stove designs. There is an urgent need for easy-to-use, inexpensive, accurate, and robust stove testing equipment for use by laboratory and field researchers around the world. ASAT and their research partner, Aprovecho Research Center (ARC), have over thirty years of experience addressing these two needs, improved cookstoves and emissions monitoring equipment, with expertise spanning the full spectrum of development from conceptual design to product manufacturing and dissemination. This includes: 1) research, design, and verification of clean biomass cookstove technology and emissions monitoring equipment; 2) mass production of quality

  16. Improving resident education in quality improvement: role for a resident quality improvement director. (United States)

    Sarwar, Ammar; Eisenberg, Ronald L; Boiselle, Phillip M; Siewert, Bettina; Kruskal, Jonathan B


    As a component of the practice-based core competency of the Accreditation Council for Graduate Medical Education, all residents must receive training to be able to evaluate and improve their patient care practices. To further enhance our overall resident quality improvement (QI) educational experience, and to ensure resident involvement in the many aspects of a quality assurance program, we have established a resident educational leadership role and have appointed a resident as resident QI director. We have designed and implemented a resident leadership position in QI in our department. A senior resident (postgraduate year 4 and above) is provided with dedicated training in QI methods, mentored opportunities to develop professional skills in QI, and didactic teaching in applications of QI to other residents. A leadership position in QI for trainees introduces this important concept early in their career. The resident QI director is provided dedicated training, receives a broader perspective of QI and is optimally positioned to introduce the concept to junior residents leading to greater acceptance of QI at a resident level. The introduction of a resident QI director enhances the importance of QI for trainees, prepares the individual for a strong academic and QI career, and improves acceptance of QI methods among trainees.

    Full Text Available Francisco José Tarazona-Santabalbina,1,2 Ángel Belenguer-Varea,1,2 Eduardo Rovira,1,2 David Cuesta-Peredó1,21Geriatric Medicine Unit, Internal Medicine Department, Hospital Universitario de la Ribera, 2Medical School, Universidad Católica de Valencia San vicente Mártir, Valencia, SpainAbstract: Hip fractures are a very serious socio-economic problem in western countries. Since the 1950s, orthogeriatric units have introduced improvements in the care of geriatric patients admitted to hospital because of hip fractures. During this period, these units have reduced mean hospital stays, number of complications, and both in-hospital mortality and mortality over the middle term after hospital discharge, along with improvements in the quality of care and a reduction in costs. Likewise, a recent clinical trial has reported greater functional gains among the affected patients. Studies in this field have identified the prognostic factors present upon admission or manifesting themselves during admission and that increase the risk of patient mortality or disability. In addition, improved care afforded by orthogeriatric units has proved to reduce costs. Nevertheless, a number of management issues remain to be clarified, such as the optimum anesthetic, analgesic, and thromboprophylactic protocols; the type of diagnostic and therapeutic approach best suited to patients with cognitive problems; or the efficiency of the programs used in convalescence units or in home rehabilitation care. Randomized clinical trials are needed to consolidate the evidence in this regard. Keywords: hip fractures, geriatric assessment, orthogeriatric care, recovery of function, mortality

    As part of the technology utilization program at the NASA Lewis Research Center, efforts are underway to transfer aerospace technologies to new areas of practical application. One such effort involves using advanced computational fluid dynamics (CFD) codes for turbomachinery to analyze the internal fluid dynamics of low-speed fans and blowers. This year, the Kirby Company in Cleveland, Ohio, approached NASA with a request for technologies that could help them improve their vacuum cleaners. Of particular interest to Kirby is the high-frequency blade-passing noise generation of their vacuum cleaner fan at low airflow rates.

  20. Understanding and improving hospice enrollment. (United States)

    Casarett, David

    Hospice is considered the "gold standard" for end-of-life care, providing dying patients and their families access to a broad array of services across settings. Despite its comprehensive approach, hospice care remains underutilized; many patients who might benefit from hospice do not enroll, or enroll only in the last days of life. This Issue Brief summarizes a series of studies that shed light on the decision making process about hospice, and describes a simple, effective way to improve referrals to hospice among nursing home residents.

  1. Improving collaborative documentation in CMS

    CERN Document Server

    Lassila-Perini, Kati


    Complete and up-to-date documentation is essential for efficient data analysis in a large and complex collaboration like CMS. Good documentation reduces the time spent in problem solving for users and software developers. The scientists in our research environment do not necessarily have the interests or skills of professional technical writers. This results in inconsistencies in the documentation. To improve the quality, we have started a multidisciplinary project involving CMS user support and expertise in technical communication from the University of Turku, Finland. In this paper, we present possible approaches to study the usability of the documentation, for instance, usability tests conducted recently for the CMS software and computing user documentation

    In this paper we propose an improvement of the EKS nuclear parton distributions for the small x region of high energy processes, where the perturbative high parton density effects cannot be disregarded. We analyze the behavior of the ratios $xG_A/xG_N$ and $F_2^A/F_2^D$ and verify that at small x they are strongly modified when compared to the EKS predictions. The implications of our results for the heavy ion collisions in RHIC and LHC are discussed.

    Jiskoot, R.J.J. (Jiskoot Autocontrol, Kent (United Kingdom))


    Accurate and reliable sampling systems are imperative when confirming natural gas' commercial value. Buyers and sellers need accurate hydrocarbon-composition information to conduct fair sale transactions. Because of poor sample extraction, preparation or analysis can invalidate the sale, more attention should be directed toward improving representative sampling. Consider all sampling components, i.e., gas types, line pressure and temperature, equipment maintenance and service needs, etc. The paper discusses gas sampling, design considerations (location, probe type, extraction devices, controller, and receivers), operating requirements, and system integration.

  5. Improved Thin, Flexible Heat Pipes (United States)

    Rosenfeld, John H.; Gernert, Nelson J.; Sarraf, David B.; Wollen, Peter J.; Surina, Frank C.; Fale, John E.


    Flexible heat pipes of an improved type are fabricated as layers of different materials laminated together into vacuum- tight sheets or tapes. In comparison with prior flexible heat pipes, these flexible heat pipes are less susceptible to leakage. Other advantages of these flexible heat pipes, relative to prior flexible heat pipes, include high reliability and greater ease and lower cost of fabrication. Because these heat pipes are very thin, they are highly flexible. When coated on outside surfaces with adhesives, these flexible heat pipes can be applied, like common adhesive tapes, to the surfaces of heat sinks and objects to be cooled, even if those surfaces are curved.

  6. Improving physics education in radiology. (United States)

    Concern is growing that the physics education of radiologists is flawed and that without knowledge of physics principles and applications, mastery of the technology of medical imaging is impaired. Furthermore, it is proposed that a mastery of imaging technology is necessary to perfect the clinical acumen of radiologists and to preserve the quality, safety, and cost-effectiveness of imaging procedures. These issues were the focus of a multiorganizational educational summit on physics education of radiologists held in January 2006 in Atlanta. Recommendations for improving the physics education and knowledge of radiologists that evolved from this summit are presented here, together with progress made to date on their fulfillment.

    Full Text Available Structured Query Language (SQL is used to obtain data from relational databases. Fuzzy improvement of SQL queries has advantages in cases when the user cannot unambiguously define selection criteria or when the user wants to examine data that almost meet the given criteria. In this paper we examine a realization of the fuzzy querying concept. For this purposes the fuzzy generalized logical condition for the WHERE part of the SQL is created. It allows users to create queries by linguistic terms. The proposed model is an extension of the SQL so that no modification inside databases has to be undertaken.

  10. Improving risk literacy in surgeons. (United States)

    Garcia-Retamero, Rocio; Cokely, Edward T; Wicki, Barbara; Joeris, Alexander


    To effectively practice evidence-based medicine, surgeons need to understand and be able to communicate health-relevant numerical information. We present the first study examining risk literacy in surgeons by assessing numeracy and surgical risk comprehension. Our study also investigated whether visual aids improve risk comprehension in surgeons with limited numeracy. Participants were 292 surgeons from 60 countries who completed an instrument measuring numeracy and evaluated the results of a randomized controlled trial including post-surgical side-effects. Half of the surgeons received this information in numbers. The other half received the information represented visually. Accuracy of risk estimation, reading latency, and estimate latency (i.e., deliberation) were assessed. Some surgeons have low numeracy and could not correctly interpret surgical risks without additional support. Visual aids made risks transparent and eliminated differences in risk understanding between more and less numerate surgeons, increasing the amount of time that less numerate surgeons spent deliberating about risks. Visual aids can be an efficient and inexpensive means of improving risk comprehension and clinical judgement in surgeons with low numerical and statistical skills. Programs designed to help professionals represent and communicate health-relevant numerical information in simple transparent graphs may unobtrusively promote informed decision making.

  11. Technology improves upper extremity rehabilitation. (United States)

    Kowalczewski, Jan; Prochazka, Arthur


    Stroke survivors with hemiparesis and spinal cord injury (SCI) survivors with tetraplegia find it difficult or impossible to perform many activities of daily life. There is growing evidence that intensive exercise therapy, especially when supplemented with functional electrical stimulation (FES), can improve upper extremity function, but delivering the treatment can be costly, particularly after recipients leave rehabilitation facilities. Recently, there has been a growing level of interest among researchers and healthcare policymakers to deliver upper extremity treatments to people in their homes using in-home teletherapy (IHT). The few studies that have been carried out so far have encountered a variety of logistical and technical problems, not least the difficulty of conducting properly controlled and blinded protocols that satisfy the requirements of high-level evidence-based research. In most cases, the equipment and communications technology were not designed for individuals with upper extremity disability. It is clear that exercise therapy combined with interventions such as FES, supervised over the Internet, will soon be adopted worldwide in one form or another. Therefore it is timely that researchers, clinicians, and healthcare planners interested in assessing IHT be aware of the pros and cons of the new technology and the factors involved in designing appropriate studies of it. It is crucial to understand the technical barriers, the role of telesupervisors, the motor improvements that participants can reasonably expect and the process of optimizing IHT-exercise therapy protocols to maximize the benefits of the emerging technology.

  12. Kidney disease: improving global outcomes. (United States)

    Eckardt, Kai-Uwe; Kasiske, Bertram L


    Kidney Disease: Improving Global Outcomes (KDIGO) is an independent organization with the mission to improve care and outcomes of patients with kidney disease worldwide through the development and coordination of clinical practice guidelines. KDIGO has established firm links with other organizations that have previously produced clinical practice guidelines in the field of kidney disease. The first three KDIGO guidelines--treatment of hepatitis C, management of bone and mineral disease, and care of kidney transplant recipients--have been finalized and the next three--acute kidney injury, management of glomerulonephritis, and management of blood pressure in chronic kidney disease--are under development. The ultimate goal is to cover most major aspects of care for patients with kidney disease. Corner stones of KDIGO's guideline development process are independent, multidisciplinary, international work groups, close collaboration with professional methodology experts who perform systematic evidence reviews, and open public review of each guideline. Grades of Recommendation Assessment, Development, and Evaluation (GRADE) methodology is applied for grading the quality of evidence and strength of recommendations. International conferences organized by KDIGO support the coordination of guideline development, assess the suitability of guideline topics and help to establish global consensus on definitions and policies.

  13. Improved Aerogel Vacuum Thermal Insulation (United States)

    Ruemmele, Warren P.; Bue, Grant C.


    An improved design concept for aerogel vacuum thermal-insulation panels calls for multiple layers of aerogel sandwiched between layers of aluminized Mylar (or equivalent) poly(ethylene terephthalate), as depicted in the figure. This concept is applicable to both the rigid (brick) form and the flexible (blanket) form of aerogel vacuum thermal-insulation panels. Heretofore, the fabrication of a typical aerogel vacuum insulating panel has involved encapsulation of a single layer of aerogel in poly(ethylene terephthalate) and pumping of gases out of the aerogel-filled volume. A multilayer panel according to the improved design concept is fabricated in basically the same way: Multiple alternating layers of aerogel and aluminized poly(ethylene terephthalate) are assembled, then encapsulated in an outer layer of poly(ethylene terephthalate), and then the volume containing the multilayer structure is evacuated as in the single-layer case. The multilayer concept makes it possible to reduce effective thermal conductivity of a panel below that of a comparable single-layer panel, without adding weight or incurring other performance penalties. Implementation of the multilayer concept is simple and relatively inexpensive, involving only a few additional fabrication steps to assemble the multiple layers prior to evacuation. For a panel of the blanket type, the multilayer concept, affords the additional advantage of reduced stiffness.

  14. Improving girls' schooling in Africa. (United States)


    The Forum for African Women Educationalists (FAWE) is working to improve schooling for girls and women. The organization has 14 national chapters and has funded 14 projects in African Countries, including a program of alternative education for out-of-school girls, a remedial mathematics and science program, help for poor students, persuading teachers to allow pregnant girls to continue their schooling after delivery, and programs which allow daughters of farmers to schedule classes around their livestock duties. FAWE also sponsored a ministerial consultation on school dropouts and adolescent pregnancy which attracted an impressive number of male African Ministers of Education. In Ghana, the FAWE chapter acts as a think tank and a pressure group. Female education issues are explored through role-playing in workshops geared to improve public awareness of the importance of educating girls, and science clinics have been designed to increase appreciation for science and mathematics among girls. FAWE has produced publications in English and French, as well as a music tape and a documentary. FAWE is funded by a variety of private and international agencies and recently received recognition from the UN's Educational, Scientific, and Cultural Organization.

  15. Pasture improvement in Spanish Dehesas (United States)

    Murillo Vilanova, M.; González López, F.


    In the south-west of the Iberian Peninsula, the dehesa is a widespread agro-silvo-pastoral land use system, characterized by a grassland with a disperse cover of oak trees and shrubs, where the main production is extensive livestock combined with agriculture and forestry. Many years of inappropriate management of dehesas (deforestation, overgrazing, excessive agricultural activities, etc.) has led to the degradation of vegetation and soils in extensive areas, causing reductions in biomass and biodiversity, affecting the permanence of plants and causing important losses of palatable species. As there is growing interest in these wooded rangeland ecosystems due to their economic importance and high environmental value, the recovery of the original pasture biodiversity and the increase of productivity, together with the conservation of the environment, are the main goals in these areas of low productive potential, degraded and subject to soil erosion. Soil and climate conditions have a great influence on grassland production, with rainfall producing strong seasonal and interannual variations. These natural pastures, mainly composed of summer withering annual species, reach maximum productions in spring and register low values in autumn, slowing down in winter. During the summer dry season, the wilting pastures can offer a good forage for animals. Autochthonous annual legumes play an important role because they are well adapted to local edaphic and climatic conditions and produce hard seeds which germinate in autumn. This helps them to survive the frequent droughts and offer a high quality forage, which is a valuable complement to other pasture plants with lower protein content. Therefore, for several decades, legume seeding combined with the application of phosphate fertilizer has been the most common strategy used to improve pastures in SW Spain, where dehesas cover an area of about four million hectares. This paper examines the whole process of pasture improvement

  19. [Improving the surgeon's image: introduction]. (United States)

    Tajima, Tomoo


    The number of medical students who aspire to become surgeons has been decreasing in recent years. With a vicious spiral in the decreasing number and the growing deterioration of surgeons' working conditions, there is fear of deterioration of surgical care and subsequent disintegration of overall health care in Japan. The purpose of this issue is to devise a strategy for improving surgeons' image and their working conditions to attract future medical students. However, we cannot expect a quick cure for the problem of the decreasing number of applicants for surgery since this issue is deeply related to many fundamental problems in the health care system in Japan. The challenge for surgical educators in coming years will be to solve the problem of chronic sleep deprivation and overwork of surgery residents and to develop an efficient program to meet the critical educational needs of surgical residents. To solve this problem it is necessary to ensure well-motivated surgical residents and to develop an integrated research program. No discussion of these issues would be complete without attention to the allocation of scarce medical resources, especially in relation to financial incentives for young surgeons. The authors, who are conscientious representatives of this society, would like to highlight these critical problems and issues that are particularly relevant to our modern surgical practice, and it is our sincere hope that all members of this society fully recognize these critical issues in the Japanese health care system to take leadership in improving the system. With the demonstration of withholding unnecessary medical conducts we may be able to initiate a renewal of the system and eventually to fulfill our dreams of Japan becoming a nation that can attract many patients from all over the world. Furthermore, verification of discipline with quality control and effective surgical treatment is needed to avoid criticism by other disciplines for being a self

    An OLED may include regions of a material having a refractive index less than that of the substrate, or of the organic region, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED. Methods for fabricating such a transparent or top-emitting OLED is also provided.

    Giacomini, T


    IPMs measure in a non-destructive way the profile of ion beams independent whether the beam is bunched or not. Our application is the heavy ion synchrotron SIS, which can accelerate ions with a large variety of different masses and charges. The IPM is used to obtain information about the beam matching, the electron cooling and to support for any kind of machine experiments. To ensure reliable function and to increase the data accuracy we executed some important mechanical improvements. The resistive e-field plates were replaced by discrete electrodes. We designed a new MCP-Phosphor-screen assembly of rectangular shape and large active area and in addition a module with a filament mounted in meander shape to monitor the degradation of the MCPs. The whole device was planned with respect of high field uniformity and small mechanical dimensions at a large clearance for the beam.

    Jackson, M. [Univ. of Nevada, Las Vegas, NV (United States)


    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

  11. In Brief: Improving science education (United States)

    Showstack, Randy


    Over the course of the next decade, 100,000 science, technology, engineering, and math (STEM) teachers should be recruited in the United States, and 1000 new STEM-focused schools should be created, according to a 16 September report, “Prepare and inspire: K-12 education in science, technology, engineering, and math (STEM) for America's future.” Noting that the United States lags behind other nations in STEM education at the elementary and secondary levels, the report, prepared by the President's Council of Advisors on Science and Technology, also recommends improving federal coordination and leadership on STEM education and supporting a state-led movement for shared standards in math and science. The release of the report coincides with President Barack Obama's announcement of the launch of Change the Equation, an organization that aims to help with math and science education.

  14. Improvements in ECN Wake Model

    Energy Technology Data Exchange (ETDEWEB)

    Versteeg, M.C. [University of Twente, Enschede (Netherlands); Ozdemir, H.; Brand, A.J. [ECN Wind Energy, Petten (Netherlands)


    Wind turbines extract energy from the flow field so that the flow in the wake of a wind turbine contains less energy and more turbulence than the undisturbed flow, leading to less energy extraction for the downstream turbines. In large wind farms, most turbines are located in the wake of one or more turbines causing the flow characteristics felt by these turbines differ considerably from the free stream flow conditions. The most important wake effect is generally considered to be the lower wind speed behind the turbine(s) since this decreases the energy production and as such the economical performance of a wind farm. The overall loss of a wind farm is very much dependent on the conditions and the lay-out of the farm but it can be in the order of 5-10%. Apart from the loss in energy production an additional wake effect is formed by the increase in turbulence intensity, which leads to higher fatigue loads. In this sense it becomes important to understand the details of wake behavior to improve and/or optimize a wind farm layout. Within this study improvements are presented for the existing ECN wake model which constructs the fundamental basis of ECN's FarmFlow wind farm wake simulation tool. The outline of this paper is as follows: first, the governing equations of the ECN wake farm model are presented. Then the near wake modeling is discussed and the results compared with the original near wake modeling and EWTW (ECN Wind Turbine Test Site Wieringermeer) data as well as the results obtained for various near wake implementation cases are shown. The details of the atmospheric stability model are given and the comparison with the solution obtained for the original surface layer model and with the available data obtained by EWTW measurements are presented. Finally the conclusions are summarized.

  15. Improving the teaching of econometrics

    Directory of Open Access Journals (Sweden)

    David F. Hendry


    Full Text Available We recommend a major shift in the Econometrics curriculum for both graduate and undergraduate teaching. It is essential to include a range of topics that are still rarely addressed in such teaching, but are now vital for understanding and conducting empirical macroeconomic research. We focus on a new approach to macro-econometrics teaching, since even undergraduate econometrics courses must include analytical methods for time series that exhibit both evolution from stochastic trends and abrupt changes from location shifts, and so confront the “non-stationarity revolution”. The complexity and size of the resulting equation specifications, formulated to include all theory-based variables, their lags and possibly non-linear functional forms, as well as potential breaks and rival candidate variables, places model selection for models of changing economic data at the centre of teaching. To illustrate our proposed new curriculum, we draw on a large UK macroeconomics database over 1860–2011. We discuss how we reached our present approach, and how the teaching of macro-econometrics, and econometrics in general, can be improved by nesting so-called “theory-driven” and “data-driven” approaches. In our methodology, the theory-model’s parameter estimates are unaffected by selection when the theory is complete and correct, so nothing is lost, whereas when the theory is incomplete or incorrect, improved empirical models can be discovered from the data. Recent software like Autometrics facilitates both the teaching and the implementation of econometrics, supported by simulation tools to examine operational performance, designed to be feasibly presented live in the classroom.

  16. Improvement of radioimmunotherapy using pretargeting

    Directory of Open Access Journals (Sweden)

    Eric eFrampas


    Full Text Available During the past two decades, considerable research has been devoted to radionuclide therapy using radiolabelled monoclonal antibodies and receptor binding agents. Conventional Radioimmunotherapy (RIT is now an established and important tool in the treatment of hematologic malignancies such as Non-Hodgkin lymphoma. For solid malignancies, the efficacy of RIT has not been as successful due to lower radiosensitivity, difficult penetration of the antibody into the tumor and potential excessive radiation to normal tissues. Innovative approaches have been developed in order to enhance tumor absorbed dose while limiting toxicity to overcome the different limitations due to the tumor and host characteristics.Pretargeting techniques (pRIT are a promising approach that consists of decoupling the delivery of a tumor monoclonal antibody (mAb from the delivery of the radionuclide. This results in a much higher tumor-to-normal tissue ratio and is favorable for therapy as well and imaging. This includes various strategies based on avidin/streptavidin-biotin, DNA-complementary DNA and bispecific antibody-hapten bindings. PRIT continuously evolves with the investigation of new molecular constructs and the development of radiochemistry. Pharmacokinetics improve dosimetry depending on the radionuclides used (alpha, beta and Auger emitters with prediction of tumor response and host toxicities. New constructs such as the Dock and Lock technology allow production of a variety of mABs directed against tumor-associated antigens. Survival benefit has already been shown in medullary thyroid carcinoma. Improvement in delivery of radioactivity to tumors with these pretargeting procedures associated with reduced hematologic toxicity will become the next generation of RIT. The following review addresses actual technical and clinical considerations and future development of pRIT.

  17. Discoid lupus erythematosus-related squamous cell carcinoma of the lip in an HIV-seropositive black male. (United States)

    Molomo, Edward M; Bouckaert, Michael; Khammissa, Razia A G; Motswaledi, Hendrick M; Lemmer, Johan; Feller, Liviu


    Discoid lupus erythematosus (DLE) is an autoimmune disease commonly affecting sun-exposed areas of the skin. Subjects with DLE have high-levels of plasmacytoid dendritic cells -derived interferon-α, which mediates both loss of immune tolerance to self-antigens and exaggerated inflammatory state, and supports proliferation and differentiation of hyperactive B-cells. In a few cases, DLE of the lips, scalp, ears or nose may eventually progress to squamous cell carcinoma (SCC). Photosensitivity and the long-standing immune-mediated chronic inflammation and dysregulated healing characterized by atrophy, hypopigmentation or scarring inherent to DLE are risk factors for progression to SCC. We review some aspects of the pathogenesis of DLE and the possible roles of inflammation and photosensitivity in the carcinomatous transformation of DLE keratinocytes, and present an illustrative case of DLE of the lower lip in an HIV-tuberculosis co-infected black person, that progressed to SCC.

  18. Quantile Kriging: improving the uncertainty (United States)

    Lebrenz, Henning; Bárdossy, András.


    The state-of-the-art interpolation method for hydrological variables is Kriging, providing a linear estimated expectation value Z*[u] and an associated uncertainty, expressed as estimated variance σK2(u), at the unknown location u. However, the spatial distribution of the uncertainty is solely depended on the spatial structure of the known locations (i.e.: gauges) and their global variance, but not on the magnitude of Z*[u]. The objective of this study is to develop a Kriging method in order to improve the associated uncertainty by relating it to Z*[u]: As a first step, an assumed theoretical distribution (e.g.: Γ- distribution, Weibull-distribution) was fitted to the recorded monthly precipitation values from raingauges in South Africa by (1) the Method of Moments or (2) Maximum Likelihood Method. The resulting quantiles W and the distribution parameters ? and λ were subsequently interpolated to unknown locations using External Drift Kriging (EDK, drift: altitude). The expectation values of the precipitation and the corresponding uncertainty, originating from the estimated variance σK2(u) of the quantiles W, were back-calculated using the 2-point Rosenblueth method. Secondly, some modifications were introduced to the parameters: a) instead of the distribution parameters ? and λ, the sampling mean x and the sample variance σ2 were interpolated and b) the dependent parameters were orthogonalised using a Principal Component Analysis (PCA) prior to interpolation. Thirdly, the quantiles were transformed a) for each time step into a Beta-distribution and subsequently by a Normal-Score transformation or b) for each raingauge by a Normal-Score transformation. Both transformations are converting quantiles into a Gaussian distribution which is implicitly assumed by Kriging. For the different modifications and transformations, a cross-validation of the expectation values and the associated uncertainties was performed and compared to the results of the 'normal' EDK

  19. Improving Value in Neonatal Intensive Care. (United States)

    Ho, Timmy; Zupancic, John A F; Pursley, DeWayne M; Dukhovny, Dmitry


    Work within the US health care system has sought to improve outcomes, decrease costs, and improve the patient experience. Combining those three elements leads to value-added care. Quality improvement within neonatology has focused primarily on the improvement of clinical outcomes without explicit consideration of cost. Future improvement efforts in neonatology should consider opportunities to decrease or eliminate waste, and improve outcomes. Consideration of how a change affects all stakeholders reveals potential cost-saving opportunities, and developing aims with value in mind facilitates understanding and goal-setting with senior administrative leaders.

  20. Strategies for improving employee retention. (United States)

    Verlander, Edward G; Evans, Martin R


    This article proposes a solution to the perennial problem of talent retention in the clinical laboratory. It includes the presentation of 12 strategies that may be used to significantly improve institutional identity formation and establishment of the psychological contract that employees form with laboratory management. Identity formation and psychological contracting are deemed as essential in helping reduce employee turnover and increase retention. The 12 conversational strategies may be used as a set of best practices for all employees, but most importantly for new employees, and should be implemented at the critical moment when employees first join the laboratory. This time is referred to as "retention on-boarding"--the period of induction and laboratory orientation. Retention on-boarding involves a dialogue between employees and management that is focused on the psychological, practical, cultural, and political dimensions of the laboratory. It is placed in the context of the modern clinical laboratory, which is faced with employing and managing Generation X knowledge workers. Specific topics and broad content areas of those conversations are outlined.

    Halbgewachs, Ronald D.; Chavez, Adrian R.


    Process Control System (PCS) and Industrial Control System (ICS) security is critical to our national security. But there are a number of technological, economic, and educational impediments to PCS owners implementing effective security on their systems. Sandia National Laboratories has performed the research and development of the OPSAID (Open PCS Security Architecture for Interoperable Design), a project sponsored by the US Department of Energy Office of Electricity Delivery and Energy Reliability (DOE/OE), to address this issue. OPSAID is an open-source architecture for PCS/ICS security that provides a design basis for vendors to build add-on security devices for legacy systems, while providing a path forward for the development of inherently-secure PCS elements in the future. Using standardized hardware, a proof-of-concept prototype system was also developed. This report describes the improvements and capabilities that have been added to OPSAID since an initial report was released. Testing and validation of this architecture has been conducted in another project, Lemnos Interoperable Security Project, sponsored by DOE/OE and managed by the National Energy Technology Laboratory (NETL).

  2. Improvement of biodiesel methanol blends

    Y. Datta Bharadwaz


    Full Text Available The main objective of this work was to improve the performance of biodiesel–methanol blends in a VCR engine by using optimized engine parameters. For optimization of the engine, operational parameters such as compression ratio, fuel blend, and load are taken as factors, whereas performance parameters such as brake thermal efficiency (Bth and brake specific fuel consumption (Bsfc and emission parameters such as carbon monoxide (CO, unburnt hydrocarbons (HC, Nitric oxides (NOx and smoke are taken as responses. Experimentation is carried out as per the design of experiments of the response surface methodology. Optimization of engine operational parameters is carried out using Derringers Desirability approach. From the results obtained it is inferred that the VCR engine has maximum performance and minimum emissions at 18 compression ratio, 5% fuel blend and at 9.03 kg of load. At this optimized operating conditions of the engine the responses such as brake thermal efficiency, brake specific fuel consumption, carbon monoxide, unburnt hydrocarbons, nitric oxide, and smoke are found to be 31.95%, 0.37 kg/kW h, 0.036%, 5 ppm, 531.23 ppm and 15.35% respectively. It is finally observed from the mathematical models and experimental data that biodiesel methanol blends have maximum efficiency and minimum emissions at optimized engine parameters.

  4. Biotechnological improvement of ornamental plants

    Directory of Open Access Journals (Sweden)

    Flavia Soledad Darqui


    Full Text Available The discovery of commercial transgenic varieties of orange petunias sold in Europe and the United States although they had never reached the approved status, and the consequent recommendation to destroy them, was the trigger to discuss about biotechnological improvement of ornamental plants. Inside the restricted world of 26 vegetal transgenic species, according to the ISAAA’s reports (, there are three ornamental species: carnation, rose and the Beijing University developed petunia; all of them with the same trait, a change in their colour. On the other hand, in 2014, the whole-genome sequence of carnation appeared which was the first and until now the only one among ornamental species. In this context, we review the publications from the last five years in petunia, rose, chrysanthemum and carnation. In these papers there are detailed descriptions of modification of the cascade of genes and transcription factors involved in stress situations, in different developmental stages and their regulation through different plant hormones. This knowledge will allow breeding for better and new varieties with changes in their abiotic or biotic stress tolerance, altered growth or yield and modified product quality as colour or fragrance.

  5. Method to improve superconductor cable (United States)

    Borden, A.R.


    A method is disclosed of making a stranded superconductor cable having improved flexing and bending characteristics. In such method, a plurality of superconductor strands are helically wound around a cylindrical portion of a mandrel which tapers along a transitional portion to a flat end portion. The helically wound strands form a multistrand hollow cable which is partially flattened by pressure rollers as the cable travels along the transitional portion. The partially flattened cable is impacted with repeated hammer blows as the hollow cable travels along the flat end portion. The hammer blows flatten both the internal and the external surfaces of the strands. The cable is fully flattened and compacted by two sets of pressure rollers which engage the flat sides and the edges of the cable after it has traveled away from the flat end portion of the mandrel. The flattened internal surfaces slide easily over one another when the cable is flexed or bent so that there is very little possibility that the cable will be damaged by the necessary flexing and bending required to wind the cable into magnet coils.

  6. Does Telecare Improve Interorganisational Collaboration?

    Directory of Open Access Journals (Sweden)

    Jannie Kristine Bang Christensen


    Full Text Available Introduction: Previous studies have suggested that telecare can improve interorganisational collaboration within fragmented health care systems, yet this outcome has not been examined in a large-scale setting. This study explores the effects of a large-scale interorganisational telecare programme in Denmark based on home-monitoring on collaboration in a telecare network between municipalities, hospitals, and general practitioners. Methodology: Semi-structured interviews and observations of collaborating health professionals from the municipalities, hospitals, and general practitioners were undertaken and then repeated a year later. Collaboration was analysed both at the interorganisational network level and within each part of the network, including its interrelations. Results: Collaboration between municipalities and general practitioners was initially intensified as a result of implementing telecare, though this changed over time as the first start-up obstacles were overcome and the patients became more active in their treatment. Conversely, collaboration between 'hospitals and municipalities' and 'hospitals and general practitioners' was unaffected by telecare. Discussion: Changes in collaboration among municipal nurses, general practitioners, and hospital staff were related to dependency structures and municipalities’ newly gained central role in a telecare network. While the telecare network was initially characterised by asymmetrical dependency structures, these were partially equalised over time because of the municipalities’ new position in the network.

    This research project proposes to develop novel new approaches of improving the radioimmunodetection and radioimmunotherapy of malignancies by augmenting retention of radioimmunoconjugates by tumor cells. The approaches shown to be effective in these laboratory experiments will subsequently be incorporated into out ongoing clinical trials in patients. Specific project objectives include: to study the rates of endocytosis, intracellular routing, and metabolic degradation of radiolabeled monoclonal antibodies targeting tumor-associated antigens on human leukemia and lymphoma cells; To examine the effects of lysosomotropic amines (e.g. chloroquine, amantadine), carboxylic ionophores (monensin, nigericin), and thioamides (propylthiouracil), on the retention of radiolabeled MoAbs by tumor cells; to examine the impact of newer radioiodination techniques (tyramine cellobiose, paraiodobenzoyl) on the metabolic degradation of radioiodinated antibodies; to compare the endocytosis, intracellular routing, and degradation of radioimmunoconjugates prepared with different radionuclides ({sup 131}Iodine, {sup 111}Indium, {sup 90}Yttrium, {sup 99m}Technetium, {sup 186}Rhenium); and to examine the utility of radioimmunoconjugates targeting oncogene products for the radioimmunotherapy and radioimmunoscintigraphy of cancer.

  8. Creating visual explanations improves learning. (United States)

    Bobek, Eliza; Tversky, Barbara


    Many topics in science are notoriously difficult for students to learn. Mechanisms and processes outside student experience present particular challenges. While instruction typically involves visualizations, students usually explain in words. Because visual explanations can show parts and processes of complex systems directly, creating them should have benefits beyond creating verbal explanations. We compared learning from creating visual or verbal explanations for two STEM domains, a mechanical system (bicycle pump) and a chemical system (bonding). Both kinds of explanations were analyzed for content and learning assess by a post-test. For the mechanical system, creating a visual explanation increased understanding particularly for participants of low spatial ability. For the chemical system, creating both visual and verbal explanations improved learning without new teaching. Creating a visual explanation was superior and benefitted participants of both high and low spatial ability. Visual explanations often included crucial yet invisible features. The greater effectiveness of visual explanations appears attributable to the checks they provide for completeness and coherence as well as to their roles as platforms for inference. The benefits should generalize to other domains like the social sciences, history, and archeology where important information can be visualized. Together, the findings provide support for the use of learner-generated visual explanations as a powerful learning tool.

  9. Surface Improvement of Halloysite Nanotubes

    Directory of Open Access Journals (Sweden)

    Tayser Sumer Gaaz


    Full Text Available A novel development on halloysite-polyvinyl alcohol (HNTs-PVA nanocomposites has been conducted using malonic acid (MA by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (XRD-2θ-peak, suggesting that MA has no or little influence on the crystallographic structure of the HNTs-PVA. Images taken by field emission scanning electron microscope (FESEM suggest possible effects of MA on the morphology and internal features of HNTs-PVA by reducing the agglomeration of HNTs, which is considered a decisive step in improving the surface qualities of HNTs. Investigating the samples using the Brunauer–Emmelt–Teller (BET technique showed that the surface area was increased by about 10 times, reaching the second highest recorded results compared to the HNTs, which could be considered a breakthrough step in enhancing the properties of HNTs-PVA due to MA crosslinking.

    Visual impairment affects nearly 285 million people worldwide. Although there has been much progress in combating the burden of visual impairment through initiatives such as VISION 2020, barriers to progress, especially in African countries, remain high. The Rwandan Ministry of Health has formed partnerships with several nongovernmental organizations and has worked to integrate their efforts to prevent and treat visual impairment, including presbyopia. Rwanda, an eastern African country of approximately 11 million people. The Rwandan Ministry of Health developed a single national plan that allows key partners in vision care to coordinate more effectively in measuring eye disease, developing eye care infrastructure, building capacity, controlling disease, and delivering and evaluating services. Collaboration between stakeholders under a single national plan has ensured that resources and efforts are complementary, optimizing the ability to provide eye care. Improved access to primary eye care and insurance coverage has increased demand for services at secondary and tertiary levels. A comprehensive strategy that includes prevention as well as a supply chain for glasses and lenses is needed.

  11. Improving methods of resident selection. (United States)

    Prager, Jeremy D; Myer, Charles M; Hayes, Kay M; Myer, Charles M; Pensak, Myles L


    Applying the concept of the ACGME general competencies, it is possible to define the essential job objectives and competencies of a junior otolaryngology resident. The objective of this study is to incorporate commercially available tools of business in the identification of competencies specific to the junior otolaryngology resident and develop behavioral-based interview questions and techniques designed to identify these qualities in candidates for residency. Institution of a pilot program involving a focus group within an otolaryngology department, a professional development consultant, commercial business software for occupational analysis and personnel selection, and an interview technique training seminar for faculty and residents. In coordination with a university-based professional development consultant, a formal job analysis was conducted to define the job objectives and competencies of a junior otolaryngology resident. These results were used to generate behavioral-based interview questions for use in the resident selection process. All interviewing faculty and residents were trained in behavioral-based interviewing. Occupational objectives for the junior resident position specific to a particular university department of otolaryngology were identified. Additionally, the essential skills, areas of knowledge, and competencies were identified. Behavioral-based questions specific to the competencies were created and incorporated into the current resident selection interview. Using tools of occupational analysis and personnel selection, a list of job objectives and competencies for the junior otolaryngology resident can be created. Using these results, behavioral-based interviews may be implemented to complement traditional interviews with the ultimate goal of improving candidate selection.

    This report presents results of a project to design and fabricate an improved photovoltaic concentrator module. Using previous work as a baseline, this study conducted analyses and testing to select major module components and design features. The lens parquet and concentrator solar cell were selected from the highest performing, available components. A single 185X point-focus module was fabricated by the project team and tested at Sandia. Major module characteristics include a 6 by 4 compression-molded acrylic lens parquet (0.737 m{sup 2} area), twenty-four 0.2 ohms-cm, FZ, p-Si solar cells (1.56 cm{sup 2} area) soldered to ceramic substrates and copper heat spreaders, and an aluminized steel housing with corrugated bottom. This project marked the first attempt to use prismatic covers on solar cells in a high-concentration, point-focus application. Cells with 15 percent metallization were obtained, but problems with the fabrication and placement of prismatic covers on these cells lead to the decision not to use covers in the prototype module. Cell assembly fabrication, module fabrication, and module optical design activities are presented here. Test results are also presented for bare cells, cell assemblies, and module. At operating conditions of 981 watts/m{sup 2} DNI and an estimated cell temperature of 65{degrees}C, the module demonstrated an efficiency of 13.9 percent prior to stressed environmental exposure. 12 refs., 56 figs., 7 tabs.

    Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimator, and test its performance using the maxBCG cluster catalog. Our new estimator significantly reduces the variance in the L{sub X}-richness relation, from {sigma}{sub lnL{sub X}}{sup 2} = (0.86 {+-} 0.02){sup 2} to {sigma}{sub lnL{sub X}}{sup 2} = (0.69 {+-} 0.02){sup 2}. Relative to the maxBCG richness estimate, it also removes the strong redshift dependence of the richness scaling relations, and is significantly more robust to photometric and redshift errors. These improvements are largely due to our more sophisticated treatment of galaxy color data. We also demonstrate the scatter in the L{sub X}-richness relation depends on the aperture used to estimate cluster richness, and introduce a novel approach for optimizing said aperture which can be easily generalized to other mass tracers.

  14. Improving Survival in Decompensated Cirrhosis

    Directory of Open Access Journals (Sweden)

    Amar Nath Mukerji


    Full Text Available Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

  15. Commercial sector can improve access. (United States)

    Finger, W R


    This article discusses the improved accessibility to family planning (FP) services made possible by expanding services among private physicians and through social marketing in developing countries. Encouraging private sector (PS) FP is a way to ease the caseload of public FP facilities and creating the potential for attracting more lower-income clients. Few developing countries have a "viable commercial market" for contraceptives. Commercial success depends upon a secure supply of FP supplies, well-trained providers, and consumer demand. Consumers want affordable, high-quality, and convenient services. Governments must ensure that regulations do not hamper PS programs. Public and private programs should not compete in ways that are counterproductive. The commercial sector includes private physicians, clinics, pharmacies, or hospitals without public subsidies. Public funding might be used to encourage PS distribution, especially condoms and messages about HIV and sexually transmitted disease prevention. Messages may target specific audiences and promote an appealing logo and packaging. SOMARC in Turkey promotes a network of commercial health care facilities that offer high quality FP at affordable prices. The model includes provider training, quality of care monitoring, marketing, a hotline, posted prices, and prices set by consumer affordability surveys. This model is being tried in both Nepal and the Philippines. Commercial marketing has been successful in Latin America, North Africa, and the Middle East. Commercial expansion and survival is dependent upon the satisfaction of consumer preferences for convenience, greater access, better confidentiality, and quality. Examples from Zimbabwe and Romania are used to show strategies for training private providers. Private providers will become involved, for instance, by offering targeted training programs.

  16. Culture shock: Improving software quality

    Energy Technology Data Exchange (ETDEWEB)

    de Jong, K.; Trauth, S.L.


    The concept of software quality can represent a significant shock to an individual who has been developing software for many years and who believes he or she has been doing a high quality job. The very idea that software includes lines of code and associated documentation is foreign and difficult to grasp, at best. Implementation of a software quality program hinges on the concept that software is a product whose quality needs improving. When this idea is introduced into a technical community that is largely ''self-taught'' and has been producing ''good'' software for some time, a fundamental understanding of the concepts associated with software is often weak. Software developers can react as if to say, ''What are you talking about. What do you mean I'm not doing a good job. I haven't gotten any complaints about my code yetexclamation'' Coupling such surprise and resentment with the shock that software really is a product and software quality concepts do exist, can fuel the volatility of these emotions. In this paper, we demonstrate that the concept of software quality can indeed pose a culture shock to developers. We also show that a ''typical'' quality assurance approach, that of imposing a standard and providing inspectors and auditors to assure its adherence, contributes to this shock and detracts from the very goal the approach should achieve. We offer an alternative, adopted through experience, to implement a software quality program: cooperative assistance. We show how cooperation, education, consultation and friendly assistance can overcome this culture shock. 3 refs.

  17. Improving and expanding NGO programmes. (United States)

    Mukhopadhyay, A


    India has massive problems and is in need of improving and expanding non governmental organization (NGO) programs by broadening the scope of NGO activities, identifying successful NGO activities, and by moving closer to the community to participate in their activities. The problems and experience in the last few decades indicate that with expansion bureaucratization takes place. The institution begins to depend on donors and follows donor-driven agendas. As more money is given by the government, many more so called GONGO or Government-NGO projects materialize. Another problem is that the government almost always approaches the NGOs for the implementation of a project, and there is complete lack of cooperation at the planning stage. The government is considering a loan from the World Bank and UNICEF to launch a mother and child health program, but there has not been any discussion with the dozens of people who have worked on issues concerning mother and child health issues for many years. There is a need to be more demanding of the government about the various programs that are implemented for the government. Very few NGO health and family welfare projects are run by ordinary nurses or ordinary Ayurvedic doctors under ordinary conditions. Since successful NGO work has to be extended to other parts of the country, they will have to be run by ordinary people with very ordinary resources. Over the years, the NGO community has become preoccupied with its own agenda. Today, despite very sophisticated equipment and infrastructure, they are not able to reach the 60,000-70,000 workers and employees. Some of the ideas with respect to the strengthens and weaknesses of community participation have to be shared. NGOs should include all the existing non governmental organizations throughout the country, and have a dialogue with other nongovernmental bodies such as trade unions. The challenge is to adjust the current agenda, prevailing style, and present way of operating and move

  18. Flipperons for Improved Aerodynamic Performance (United States)

    Mabe, James H.


    Lightweight, piezoelectrically actuated bending flight-control surfaces have shown promise as means of actively controlling airflows to improve the performances of transport airplanes. These bending flight-control surfaces are called flipperons because they look somewhat like small ailerons, but, unlike ailerons, are operated in an oscillatory mode reminiscent of the actions of biological flippers. The underlying concept of using flipperons and other flipperlike actuators to impart desired characteristics to flows is not new. Moreover, elements of flipperon-based active flow-control (AFC) systems for aircraft had been developed previously, but it was not until the development reported here that the elements have been integrated into a complete, controllable prototype AFC system for wind-tunnel testing to enable evaluation of the benefits of AFC for aircraft. The piezoelectric actuator materials chosen for use in the flipperons are single- crystal solid solutions of lead zinc niobate and lead titanate, denoted generically by the empirical formula (1-x)[Pb(Zn(1/3)Nb(2/3))O3]:x[PbTiO3] (where x<1) and popularly denoted by the abbreviation PZN-PT. These are relatively newly recognized piezoelectric materials that are capable of strain levels exceeding 1 percent and strain-energy densities 5 times greater than those of previously commercially available piezoelectric materials. Despite their high performance levels, (1-x)[Pb(Zn(1/3)Nb(2/3))O3]:x[PbTiO3] materials have found limited use until now because, relative to previously commercially available piezoelectric materials, they tend to be much more fragile.

  19. Does sleep improve memory organization?

    Directory of Open Access Journals (Sweden)

    Masashi eTakeuchi


    Full Text Available Sleep can integrate information into existing memory networks, look for common patterns and distill overarching rules, or simply stabilize and strengthen the memory exactly as it was learned. Recent research has shown that sleep facilitates abstraction of gist information as well as integration across multiple memories, insight into hidden solutions, and even the ability to make creative connections between distantly related ideas and concepts. To investigate the effect of sleep on memory organization, thirty-five normal volunteers were randomly assigned either to the sleep (n=17 or wake group (n=18. The sleep subjects performed the Japanese Verbal Learning Test (JVLT, a measure of learning and memory, three times in the evening, and slept. On the following morning (9 hours later, they were asked to recall the words on the list. The wake subjects took the same test in the morning, and were asked to recall the words in the same time interval as in the sleep group. The Semantic Clustering Ratio (SCR, divided by the total number of words recalled, was used as an index of memory organization. Our main interest was whether the sleep subjects elicit a greater increase in this measure from the third to the fourth assessments. Time-by-group interaction effect on SCR was not significant between the sleep group and wake group as a whole. Meanwhile, the change in the SCR between the third and fourth trials was negatively correlated with duration of nocturnal waking in the sleep group, but not other sleep indices. Based on this observation, further analysis was conducted for subjects in the sleep group who awoke nocturnally for less than 60 minutes for comparison with the wake group. A significant time-by-group interaction was noted; these good-sleepers showed a significantly greater improvement in the memory index compared with the wake subjects. These results provide the first suggestion that sleep may enhance memory organization, which requires further

  20. Improved β Decay Branching Ratios (United States)

    Iacob, V. E.; Hardy, J. C.; Golovko, V.


    The work we report here aims at increasing the precision possible in the measurement of branching ratios for superallowed β^+decays. Such highly accurate values are essential in generating precise ft-values for 0^+->0^+decays, which can then be used to test the Standard Model via the unitarity of the Cabibbo-Kobayashi-Maskawa matrix [1]. The required precision is ˜0.1% or better. While this limit was already achieved in the case of ^34Ar [2], it would have been very difficult, if not impossible, to achieve it for other β^+-decays without an upgrade to our acquisition and data-reduction systems. We have thus improved the controls over all the key elements in our experimental set-up: we now have direct control over the dead-time for the singles and coincidence channels and <0.1 mm control over the source-detector distance. In addition, we have extensively studied the efficiency of the β-detector with source-measurements tested against various Monte Carlo programs [3]. We have tested our new acquisition set-up on ^60Co and ^22Na (β^- and β^+ emitters respectively) to validate our new methods. Preliminary results on the two sources are statistically consistent with the expected values. An ^34Ar decay experiment using the new experimental configuration has already been performed and is currently analyzed. [1] J.C. Hardy and I.S. Towner, PRC 71, 055501 (2005) [2] V.

    Harel, Ziv; McQuillan, Rory; Weizman, Adam V.; Thomas, Alison; Chertow, Glenn M.; Nesrallah, Gihad; Bell, Chaim M.; Chan, Christopher T.


    Quality improvement involves a combined effort among health care staff and stakeholders to diagnose and treat problems in the health care system. However, health care professionals often lack training in quality improvement methods, which makes it challenging to participate in improvement efforts. This article familiarizes health care professionals with how to begin a quality improvement project. The initial steps involve forming an improvement team that possesses expertise in the quality of care problem, leadership, and change management. Stakeholder mapping and analysis are useful tools at this stage, and these are reviewed to help identify individuals who might have a vested interest in the project. Physician engagement is a particularly important component of project success, and the knowledge that patients/caregivers can offer as members of a quality improvement team should not be overlooked. After a team is formed, an improvement framework helps to organize the scientific process of system change. Common quality improvement frameworks include Six Sigma, Lean, and the Model for Improvement. These models are contrasted, with a focus on the Model for Improvement, because it is widely used and applicable to a variety of quality of care problems without advanced training. It involves three steps: setting aims to focus improvement, choosing a balanced set of measures to determine if improvement occurs, and testing new ideas to change the current process. These new ideas are evaluated using Plan-Do-Study-Act cycles, where knowledge is gained by testing changes and reflecting on their effect. To show the real world utility of the quality improvement methods discussed, they are applied to a hypothetical quality improvement initiative that aims to promote home dialysis (home hemodialysis and peritoneal dialysis). This provides an example that kidney health care professionals can use to begin their own quality improvement projects. PMID:27016497

  4. Can verbal working memory training improve reading? (United States)

    Banales, Erin; Kohnen, Saskia; McArthur, Genevieve


    The aim of the current study was to determine whether poor verbal working memory is associated with poor word reading accuracy because the former causes the latter, or the latter causes the former. To this end, we tested whether (a) verbal working memory training improves poor verbal working memory or poor word reading accuracy, and whether (b) reading training improves poor reading accuracy or verbal working memory in a case series of four children with poor word reading accuracy and verbal working memory. Each child completed 8 weeks of verbal working memory training and 8 weeks of reading training. Verbal working memory training improved verbal working memory in two of the four children, but did not improve their reading accuracy. Similarly, reading training improved word reading accuracy in all children, but did not improve their verbal working memory. These results suggest that the causal links between verbal working memory and reading accuracy may not be as direct as has been assumed.

To determine the hepatoprotective effect of DLE, we fed C57BL/6 mice with normal chow diet (NCD), high-fat diet (HFD), HFD supplemented with 2g/kg DLE DLE (DL), and HFD supplemented with 5 g/kg DLE (DH). We found that the HFD supplemented by DLE dramatically reduced hepatic lipid accumulation compared to HFD alone. Body and liver weights of the DL and DH groups were significantly lesser than those of the HFD group, and DLE supplementation dramatically suppressed triglyceride (TG), total cholesterol (TC), insulin, fasting glucose level in serum, and Homeostatic Model Assessment Insulin Resistance (HOMA-IR) induced by HFD. In addition, DLE treatment significantly increased activation of adenosine monophosphate (AMP)-activated protein kinase (AMPK) in liver and muscle protein. DLE significantly suppressed lipid accumulation in the liver, reduced insulin resistance, and lipid in HFD-fed C57BL/6 mice via the AMPK pathway. These results indicate that the DLE may represent a promising approach for the prevention and treatment of obesity-related nonalcoholic fatty liver disease. Copyright © 2013 Elsevier Ltd.

  15. The immediate effects of soft tissue mobilization versus therapeutic ultrasound for patients with neck and arm pain with evidence of neural mechanosensitivity: a randomized clinical trial. (United States)

    Costello, Michael; Puentedura, Emilio 'Louie' J; Cleland, Josh; Ciccone, Charles D


    Randomized clinical trial. To investigate the immediate effects of soft tissue mobilization (STM) versus therapeutic ultrasound (US) in patients with neck and arm pain who demonstrate neural mechanical sensitivity. While experts have suggested that individuals with neck and arm pain associated with neural tissue mechanical sensitivity may benefit from STM, there has been little research to investigate this hypothesis. Twenty-three patients with neck and arm pain and a positive upper limb neurodynamic test (ULNT) were randomly assigned to receive STM or therapeutic US during a single session. Outcome measures were collected immediately before and after treatment, and at 2-4 day follow-up. Primary outcomes were the Global Rating of Change (GROC), range of motion (ROM) during the ULNT, and pain rating during the ULNT. Secondary measures included the Neck Disability Index (NDI), Patient-Specific Functional Scale (PSFS), Numeric Pain Rating Scale (NPRS), and active range of shoulder abduction motion combined with the wrist neutral or wrist extension. A greater proportion of patients in the STM group reported a significant improvement on the GROC immediately after treatment (P = 0·003, STM = 75%, US = 9%), and at 2-4 day follow-up (P = 0·027, STM = 58%, US = 9%). Patients who received STM demonstrated greater improvements in ROM during ULNT (P = 0·026), PSFS (P = 0·007), and shoulder active ROM combined with wrist extension (P = 0·028). Improvements in Numeric Pain Rating Scale and pain during the ULNT were observed only in the STM group. There was no difference between groups for the NDI or shoulder abduction ROM with wrist neutral. Patients with neck and arm pain demonstrated greater improvements in ULNT ROM, GROC, and PSFS, and pain following STM than after receiving therapeutic US. Therapy, level 1b.

  6. Improved silicon carbide for advanced heat engines (United States)

    Whalen, Thomas J.


    This is the second annual technical report entitled, Improved Silicon Carbide for Advanced Heat Engines, and includes work performed during the period February 16, 1986 to February 15, 1987. The program is conducted for NASA under contract NAS3-24384. The objective is the development of high strength, high reliability silicon carbide parts with complex shapes suitable for use in advanced heat engines. The fabrication methods used are to be adaptable for mass production of such parts on an economically sound basis. Injection molding is the forming method selected. This objective is to be accomplished in a two-phase program: (1) to achieve a 20 percent improvement in strength and a 100 percent increase in Weibull modulus of the baseline material; and (2) to produce a complex shaped part, a gas turbine rotor, for example, with the improved mechanical properties attained in the first phase. Eight tasks are included in the first phase covering the characterization of the properties of a baseline material, the improvement of those properties and the fabrication of complex shaped parts. Activities during the first contract year concentrated on two of these areas: fabrication and characterization of the baseline material (Task 1) and improvement of material and processes (Task 7). Activities during the second contract year included an MOR bar matrix study to improve mechanical properties (Task 2), materials and process improvements (Task 7), and a Ford-funded task to mold a turbocharger rotor with an improved material (Task 8).

  10. Historical Improvement in Speed Skating Economy. (United States)

    Noordhof, Dionne A; van Tok, Elmy; Joosten, Florentine S J G M; Hettinga, Florentina J; Hoozemans, Marco J M; Foster, Carl; de Koning, Jos J


    Half the improvement in 1500-m speed-skating world records can be explained by technological innovations and the other half by athletic improvement. It is hypothesized that improved skating economy is accountable for much of the athletic improvement. To determine skating economy in contemporary athletes and to evaluate the change in economy over the years. Contemporary skaters of the Dutch national junior team (n = 8) skated 3 bouts of 6 laps at submaximal velocity, from which skating economy was calculated (in mL O 2 ・ kg -1 ・ km -1 ). A literature search provided historic data on skating velocity and submaximal V̇O 2 (in mL ・ kg -1 ・ min -1 ), from which skating economy was determined. The association between year and skating economy was determined using linear-regression analysis. Correcting the change in economy for technological innovations resulted in an estimate of the association between year and economy due to athletic improvement. A mean (± SD) skating economy of 73.4 ± 6.4 mL O 2 ・ kg -1 ・ km -1 was found in contemporary athletes. Skating economy improved significantly over the historical time frame (-0.57 mL O 2 ・ kg -1 ・ km -1 ・ y -1 , 95% confidence interval [-0.84, -0.31]). In the final regression model for the klapskate era, with altitude as confounder, skating economy improved with a nonsignificant -0.58 mL O 2 ・ kg -1 ・ km -1 ・ y -1 ([-1.19, 0.035]). Skating economy was 73.4 ± 6.4 mL O 2 ・ kg -1 ・ km -1 in contemporary athletes and improved over the past ~50 y. The association between year and skating economy due to athletic improvement, for the klapskate era, approached significance, suggesting a possible improvement in economy over these years.

  11. Critical success factors for performance improvement programs. (United States)

    Barron, William M; Krsek, Cathleen; Weber, Diane; Cerese, Julie


    Most health care organizations struggle with the design and implementation of effective, systemwide improvement programs. In 2000, the University HealthSystem Consortium initiated a benchmarking project to identify the organizational elements that predict a successful perfermance improvement (PI) program and that are best suited to support change initiatives. Forty-one organizations completed a survey about the presence of critical components, processes used to improve performance, and organizational PI structures. Follow-up site visits were conducted at three organizations. CRITICAL SUCCESS FACTORS FOR A PI PROGRAM: Eight organizational success factors for an effective performance improvement program were identified: (1) Strong Administrative Fxecutive and Performance Improvement Leadership, (2) Active Involvement of the Board of Trustees, (3) Effective Oversight Structure, (4) Expert Performance Improvement Staff, (5) Physician Involvement and Accountability, (6) Active Staff Involvement, (7) Effective Use of Information Resources-Data Used for Decision Making, and (8) Effective Communication Strategy. The approach offered is grounded in the belief that effective organizational structures and processes are prerequisites to improving health care delivery. Although some empirical support for the proposed model is provided, additional research will be required to determine the effectiveness of this approach.

  12. Benchmarking for Cost Improvement. Final report

    Energy Technology Data Exchange (ETDEWEB)


    The US Department of Energy`s (DOE) Office of Environmental Restoration and Waste Management (EM) conducted the Benchmarking for Cost Improvement initiative with three objectives: Pilot test benchmarking as an EM cost improvement tool; identify areas for cost improvement and recommend actions to address these areas; provide a framework for future cost improvement. The benchmarking initiative featured the use of four principal methods (program classification, nationwide cost improvement survey, paired cost comparison and component benchmarking). Interested parties contributed during both the design and execution phases. The benchmarking initiative was conducted on an accelerated basis. Of necessity, it considered only a limited set of data that may not be fully representative of the diverse and complex conditions found at the many DOE installations. The initiative generated preliminary data about cost differences and it found a high degree of convergence on several issues. Based on this convergence, the report recommends cost improvement strategies and actions. This report describes the steps taken as part of the benchmarking initiative and discusses the findings and recommended actions for achieving cost improvement. The results and summary recommendations, reported below, are organized by the study objectives.

  16. Improving the pedagogical effectiveness of medical videos. (United States)

    Iorio-Morin, Christian; Brisebois, Simon; Becotte, Annick; Mior, Frédéric


    Videos are often employed in medical cursus, yet few guidelines are available to help with their production. Mayer's cognitive theory of multimedia learning is the most cited evidence-based framework for improving pedagogical effectiveness of multimedia content. Based on this framework, we identified four workflow interventions to improve the effectiveness of video content in the context of medical education: (1) choosing appropriate content; (2) optimizing the voiceover; (3) optimizing the supporting visuals and (4) planning the shooting schedule in advance. Content creators should think about pedagogical effectiveness and aim to improve their work by applying evidence-based principles.

  1. Toward improved branch prediction through data mining.

    Energy Technology Data Exchange (ETDEWEB)

    Hemmert, K. Scott; Johnson, D. Eric (University of Texas at Austin)


    Data mining and machine learning techniques can be applied to computer system design to aid in optimizing design decisions, improving system runtime performance. Data mining techniques have been investigated in the context of branch prediction. Specifically, a comparison of traditional branch predictor performance has been made to data mining algorithms. Additionally, the possiblity of whether additional features available within the architectural state might serve to further improve branch prediction has been evaluated. Results show that data mining techniques indicate potential for improved branch prediction, especially when register file contents are included as a feature set.

  7. Improving functional value of meat products. (United States)

    Zhang, Wangang; Xiao, Shan; Samaraweera, Himali; Lee, Eun Joo; Ahn, Dong U


    In recent years, much attention has been paid to develop meat and meat products with physiological functions to promote health conditions and prevent the risk of diseases. This review focuses on strategies to improve the functional value of meat and meat products. Value improvement can be realized by adding functional compounds including conjugated linoneleic acid, vitamin E, n3 fatty acids and selenium in animal diets to improve animal production, carcass composition and fresh meat quality. In addition, functional ingredients such as vegetable proteins, dietary fibers, herbs and spices, and lactic acid bacteria can be directly incorporated into meat products during processing to improve their functional value for consumers. Functional compounds, especially peptides, can also be generated from meat and meat products during processing such as fermentation, curing and aging, and enzymatic hydrolysis. This review further discusses the current status, consumer acceptance, and market for functional foods from the global viewpoints. Future prospects for functional meat and meat products are also discussed.

  8. The unintended consequences of quality improvement. (United States)

    Bardach, Naomi S; Cabana, Michael D


    The focus on quality improvement has led to several types of initiatives in pediatric care; however, these programs may lead to potential unintended consequences. Unintended consequences of quality improvement programs that have been described are reviewed. Unintended effects on resource utilization include effects on costs, as well as the inability to apply programs across different populations and affect disparities in care. Unintended effects on provider behavior include measurement fixation behavior, as well as 'crowding out' behavior, in which gains in quality in one area may simply occur at the expense of quality of care in another. Patient preferences may not always match specific quality improvement measures. Unintended effects for patients may include decreased patient satisfaction, trust, or confidence in their provider. Recognition and anticipation of the possible unintended consequences of guideline implementation is a critical step to harnessing all the benefits of quality improvement in practice.

  15. Rituals Improve Children's Ability to Delay Gratification. (United States)

    Rybanska, Veronika; McKay, Ryan; Jong, Jonathan; Whitehouse, Harvey


    To be accepted into social groups, individuals must internalize and reproduce appropriate group conventions, such as rituals. The copying of such rigid and socially stipulated behavioral sequences places heavy demands on executive function. Given previous research showing that challenging executive functioning improves it, it was hypothesized that engagement in ritualistic behaviors improves children's executive functioning, in turn improving their ability to delay gratification. A 3-month circle time games intervention with 210 schoolchildren (Mage  = 7.78 years, SD = 1.47) in two contrasting cultural environments (Slovakia and Vanuatu) was conducted. The intervention improved children's executive function and in turn their ability to delay gratification. Moreover, these effects were amplified when the intervention task was imbued with ritual, rather than instrumental, cues. © 2017 The Authors.

  18. Improving the rigor of psychophysiology research. (United States)

    Baldwin, Scott A


    Psychology as a field is in the midst of what is sometimes called a "crisis" because false findings are prevalent. Although the focus of the methodological and substantive criticisms of psychology has focused on social psychology, psychophysiology research is not without its problems. The author discusses (a) researcher flexibility and its impact on the stability of conclusions and (b) the role power plays in the probability that a finding is true and the precision of estimates. The author uses examples and data from psychophysiological research to illustrate the problems. The author concludes with a discussion of ways to shift the practice of science to improve the reliability of findings. Suggestions for improvement include: increased power through collaboration, improved statistical and methodological training, pre-registration of studies, improved reporting standards, and shifting incentives surrounding hiring and promotion.

    Lee, Dae Soo; Lee, Jong Rim; Kim, Jong Ku [Korea Electric Power Research Institute, Taejon (Korea, Republic of)


    The purpose of this study was to identify methods for improving the construct ability of nuclear power plants. This study reviewed several references of current construction practices of domestic and overseas nuclear plants in order to identify potential methods for improving construct ability. The identified methods for improving construct ability were then evaluated based on the applicability to domestic nuclear plant construction. The selected methods are expected to reduce the construction period, improve the quality of construction, cost, safety, and productivity. Selection of which methods should be implemented will require further evaluation of construction modifications, design changes, contract revisions. Among construction methods studied, platform construction methods can be applied through construction sequence modification without significant design changes, and Over the Top construction method of the NSSS, automatic welding of RCL pipes, CLP modularization, etc., are considered to be applied after design modification and adjustment of material lead time.

  12. Quantifying the improvement of turbulence mitigation technology (United States)

    Kozacik, Stephen; Paolini, Aaron; Sherman, Ariel; Bonnett, James; Kelmelis, Eric


    Atmospheric turbulence degrades imagery by imparting scintillation and warping effects that can reduce the ability to identify key features of the subjects. While visually, a human can intuitively understand the improvement that turbulence mitigation techniques can offer in increasing visual information, this enhancement is rarely quantified in a meaningful way. In this paper, we discuss methods for measuring the potential improvement on system performance video enhancement algorithms can provide. To accomplish this, we explore two metrics. We use resolution targets to determine the difference between imagery degraded by turbulence and that improved by atmospheric correction techniques. By comparing line scans between the data before and after processing, it is possible to quantify the additional information extracted. Advanced processing of this data can provide information about the effective modulation transfer function (MTF) of the system when atmospheric effects are considered and removed, using this data we compute a second metric, the relative improvement in Strehl ratio.

    It is our objective to provide you with a step-by-step approach to conducting a kaizen blitz within two days and describe how to achieve dramatic performance improvement with employee buy-in through this process. Kaizen blitz has been used dozens of times by the authors, and in some instances the same area has been blitzed as many as four times, with significant improvements each and every time. Employees have even taken it on themselves to conduct informal blitzes as a continuing improvement effort after a formal blitz has been conducted in their area. Blitzes can succeed in a variety of environments. The morning after the employees of one company attended this presentation, they self initiated a mini-blitz and discovered opportunities for improvement that they enthusiastically presented to management.

  15. Shared Decision Making in Neonatal Quality Improvement. (United States)

    Warren, Jamie B; Wiggins, Nikki


    Since the Institute of Medicine published Crossing the Quality Chasm in 2001, healthcare systems have become more focused on improving the quality of healthcare delivery. At Oregon Health & Science University and Doernbecher Children's Hospital, we recognize the need to take an interprofessional, team-based approach to improving the care we provide to our current and future patients. We describe here an ongoing quality improvement project in the Doernbecher Neonatal Intensive Care Unit (NICU), with specific attention to the factors we believe have contributed to the implementation and early success of the project. These factors include the history of quality improvement work in our NICU and in the field of neonatology, the "dyad leadership" structure under which we operate in our NICU, and our developing understanding of the concept of "team intelligence." These elements have led to the formation of a team that can practice shared decision making and work as one to realize a shared goal.

This novel teaching method has promise to improve physician skills, but requires further validation.

  6. Improving Formwork Engineering Using the Toyota Way

    Directory of Open Access Journals (Sweden)

    Jiun-De Kuo


    Full Text Available Construction is a labor-intensive industry with formwork engineering requiring a disproportionate amount of labor and costs. Formwork accounts for approximately one-third of the cost of reinforced concrete construction, partly because traditional formwork processes frequently result in delivery delays and material waste. The purpose of this research is to adapt production concepts pioneered by Toyota (the “Toyota Way” to improve formwork engineering. The Toyota Way of production consists of four tiers of management philosophy, known as the “4Ps” model. This research adopts the 4Ps as steps for formwork improvement. The first step, “establishing long term vision,” emphasizes long term considerations for formwork improvement. Step two, “establishing value streams,” reviews formwork flows and eliminates wastage. The third step, “developing the crew,” forms mold workers as a team. The final step is “developing a culture of continuous improvement” that provides a basis for constant review and provides a basis for continuous progress. The present research used the Toyota Way to improve formwork engineering. The improvements include reductions in resource waste and increases in operational value. In the long run, the proposed model could provide a learning and growth platform for individuals, the business unit, and the company’s extended network of partners. It could also serve to spur innovative thinking in the improvement of formwork engineering.

    Purpose The purpose of this paper is to address how adult development (AD) theories can contribute to quality improvement (QI). Design/methodology/approach A theoretical analysis and discussion on how personal development empirical findings can relate to QI and Deming's four improvement knowledge domains. Findings AD research shows that professionals have qualitatively diverse ways of meaning-making and ways to approach possibilities in improvement efforts. Therefore, professionals with more complex meaning-making capacities are needed to create successful transformational changes and learning, with the recognition that system knowledge is a developmental capacity. Practical implications In QI and improvement science there is an assumption that professionals have the skills and competence needed for improvement efforts, but AD theories show that this is not always the case, which suggests a need for facilitating improvement initiatives, so that everyone can contribute based on their capacity. Originality/value This study illustrates that some competences in QI efforts are a developmental challenge to professionals, and should be considered in practice and research.

  8. Improvement in corneal scarring following bacterial keratitis. (United States)

    McClintic, S M; Srinivasan, M; Mascarenhas, J; Greninger, D A; Acharya, N R; Lietman, T M; Keenan, J D


    Bacterial keratitis results in corneal scarring and subsequent visual impairment. The long-term evolution of corneal scars has not been well described. In this case series, we identified patients who had improvement in corneal scarring and visual acuity from a clinical trial for bacterial keratitis. We searched the records of the Steroids for Corneal Ulcers Trial (SCUT) for patients who had improvement in vision between the 3-month and 12-month visits and reviewed their clinical photographs. Of the 500 patients enrolled in SCUT, five patients with large central corneal scars due to bacterial keratitis are presented. All experienced improvement in rigid contact lens-corrected visual acuity from months 3 to 12. All patients also had marked improvement in corneal opacity during the same time period. None of the patients opted to have penetrating keratoplasty. Corneal scars may continue to improve even many months after a bacterial corneal ulcer has healed. The corneal remodeling can be accompanied by considerable improvement in visual acuity, such that corneal transplantation may not be necessary.

    Full Text Available BACKGROUND: Cardiovascular disease risk increases when lipoprotein metabolism is dysfunctional. We have developed a computational model able to derive indicators of lipoprotein production, lipolysis, and uptake processes from a single lipoprotein profile measurement. This is the first study to investigate whether lipoprotein metabolism indicators can improve cardiovascular risk prediction and therapy management. METHODS AND RESULTS: We calculated lipoprotein metabolism indicators for 1981 subjects (145 cases, 1836 controls from the Framingham Heart Study offspring cohort in which NMR lipoprotein profiles were measured. We applied a statistical learning algorithm using a support vector machine to select conventional risk factors and lipoprotein metabolism indicators that contributed to predicting risk for general cardiovascular disease. Risk prediction was quantified by the change in the Area-Under-the-ROC-Curve (ΔAUC and by risk reclassification (Net Reclassification Improvement (NRI and Integrated Discrimination Improvement (IDI. Two VLDL lipoprotein metabolism indicators (VLDLE and VLDLH improved cardiovascular risk prediction. We added these indicators to a multivariate model with the best performing conventional risk markers. Our method significantly improved both CVD prediction and risk reclassification. CONCLUSIONS: Two calculated VLDL metabolism indicators significantly improved cardiovascular risk prediction. These indicators may help to reduce prescription of unnecessary cholesterol-lowering medication, reducing costs and possible side-effects. For clinical application, further validation is required.

  10. Improving leaping ability in elite rhythmic gymnasts. (United States)

    Hutchinson, M R; Tremain, L; Christiansen, J; Beitzel, J


    The purpose of this study was to improve the leaping ability of athletes in rhythmic gymnastics, a high leap demanding sport, using a controlled course of jump training. Six elite athletes underwent a course of leap training including pool training and Pilates' Method of Body Conditioning using spring controlled resistance to muscular exertion. Baseline data was obtained on a force plate that measured reaction time, leap height, and explosive power on each athlete before initiating training. After 1 month of training, leap height improved 16.2%, ground reaction time improved 50%, and explosive power improved 220%. With continued maintenance training, no decrease in effect was noted; however, no significant improvement occurred after the first month of training. At 1 yr with discontinuation of the leaping protocol but continued training within the sport, the initial gains were likewise maintained. No injuries occurred during participation in the leaping protocol. Elite rhythmic gymnasts can safely improve their leaping ability significantly through an intense course of jump training. Continued training with the leaping protocol does not appear to further enhance the benefit; however, the gains appear to be maintained at 4 months and 1 yr post training with or without additional training with the leaping protocol.

  11. Software Engineering Program: Software Process Improvement Guidebook (United States)


    The purpose of this document is to provide experience-based guidance in implementing a software process improvement program in any NASA software development or maintenance community. This guidebook details how to define, operate, and implement a working software process improvement program. It describes the concept of the software process improvement program and its basic organizational components. It then describes the structure, organization, and operation of the software process improvement program, illustrating all these concepts with specific NASA examples. The information presented in the document is derived from the experiences of several NASA software organizations, including the SEL, the SEAL, and the SORCE. Their experiences reflect many of the elements of software process improvement within NASA. This guidebook presents lessons learned in a form usable by anyone considering establishing a software process improvement program within his or her own environment. This guidebook attempts to balance general and detailed information. It provides material general enough to be usable by NASA organizations whose characteristics do not directly match those of the sources of the information and models presented herein. It also keeps the ideas sufficiently close to the sources of the practical experiences that have generated the models and information.

  12. Mobile Applications to Improve Medication Adherence. (United States)

    Haase, Jamie; Farris, Karen B; Dorsch, Michael P


    Background and Introduction: Mobile applications are useful tools to improve medication adherence. As developers continue to improve the features of existing mobile applications, pharmacists should be aware of the current features that are available to patients. There are limited studies available that discuss which applications have the most desirable features. The aim of this study was to compare available mobile applications and identify ideal application features used to improve medication adherence. As of September 5, 2014, the search terms "medication adherence" and "medication reminder" generated a total of 225 hits. Ideal application features were used to create an Application Score Card to identify applications with the highest number of ideal features. We identified 30 applications that were written in English, medication related, last updated in 2014, and did not meet any exclusion criteria. The top five applications RxNetwork, Mango Health, MyMeds, C3HealthLink, and HuCare are discussed in detail. There are numerous studies looking at medication adherence. However, current literature regarding mobile applications to improve medication adherence is lacking. This article will provide pharmacists with a brief overview of the available mobile applications and features that could be used to improve patient adherence to medications. Existing mobile applications to improve medication adherence have ideal features that could help patients take medication as prescribed. Once further research is performed to establish their efficacy, pharmacists could begin to recommend mobile applications to their patients.

  13. Continue Service Improvement at CERN Computing Centre (United States)

    Barroso Lopez, M.; Everaerts, L.; Meinhard, H.; Baehler, P.; Haimyr, N.; Guijarro, J. M.


    Using the framework of ITIL best practises, the service managers within CERN-IT have engaged into a continuous improvement process, mainly focusing on service operation. This implies an explicit effort to understand and improve all service management aspects in order to increase efficiency and effectiveness. We will present the requirements, how they were addressed and share our experiences. We will describe how we measure, report and use the data to continually improve both the processes and the services being provided. The focus is not the tool or the process, but the results of the continuous improvement effort from a large team of IT experts providing services to thousands of users, supported by the tool and its local team. This is not an initiative to address user concerns in the way the services are managed but rather an on-going working habit of continually reviewing, analysing and improving the service management processes and the services themselves, having in mind the currently agreed service levels and whose results also improve the experience of the users about the current services.

  14. Improving primary percutaneous coronary intervention performance in an urban minority population using a quality improvement approach. (United States)

    Bhalla, Rohit; Yongue, Brandon G; Currie, Brian P; Greenberg, Mark A; Myrie-Weir, Jacqueline; Defino, Maryrose; Esses, David; Menegus, Mark A; McAllen, Susan J; Monrad, E Scott; Galhotra, Sanjay; Kalkut, Gary


    It has been well established that there are racial and ethnic disparities in cardiovascular care. Quality improvement initiatives have been recommended to proactively address these disparities. An initiative was implemented to improve timeliness of and access to primary percutaneous coronary intervention (PCI) procedures among myocardial infarction patients at an academic medical center serving a predominantly minority population. The effort was part of a national quality improvement collaborative focused on improving cardiovascular care for Hispanic/Latino and African American/ black populations. The proportion of primary PCI procedures performed within 90 minutes improved significantly from 17% in the first quarter of 2006 to 93% in the fourth quarter of 2008 (P < .001). There were no significant differences in the frequency with which Hispanic/Latino or African American/black patients received primary PCI therapy in comparison to nonmembers of these groups. Quality improvement techniques can improve the quality of and access to acute cardiovascular care for minority populations.

  15. Development of classification criteria for discoid lupus erythematosus: Results of a Delphi exercise. (United States)

    Elman, Scott A; Joyce, Cara; Nyberg, Filippa; Furukawa, Fukumi; Goodfield, Mark; Hasegawa, Minoru; Marinovic, Branka; Szepietowski, Jacek C; Dutz, Jan; Werth, Victoria P; Merola, Joseph F


    No classification criteria currently exist for discoid lupus erythematosus (DLE), which has led to problematic heterogeneity in both observational and interventional research efforts. We sought to develop DLE classification criteria based on consensus of international expert opinion of relevant stakeholders in the field. Using a Delphi consensus process and nominal group techniques, potential items for classification criteria were generated. Experts ranked items in terms of their appropriateness and ability to discriminate DLE from other diagnoses, and items were subsequently eliminated using consensus exercises. A final list of 12 clinical and histopathologic items was generated for potential inclusion into a set of DLE classification criteria through a formal ongoing validation process. The participants are predominantly composed of DLE experts in North America and Europe. This work represents a key step toward the development of formal DLE classification criteria.

  16. Improving global health: counting reasons why. (United States)

    Selgelid, Michael J


    This paper examines cumulative ethical and self-interested reasons why wealthy developed nations should be motivated to do more to improve health care in developing countries. Egalitarian and human rights reasons why wealthy nations should do more to improve global health are that doing so would (1) promote equality of opportunity (2) improve the situation of the worst-off, (3) promote respect of the human right to have one's most basic needs met, and (4) reduce undeserved inequalities in well-being. Utilitarian reasons for improving global health are that this would (5) promote the greater good of humankind, and (6) achieve enormous benefits while requiring only small sacrifices. Libertarian reasons are that this would (7) amend historical injustices and (8) meet the obligation to amend injustices that developed world countries have contributed to. Self-interested reasons why wealthy nations should do more to improve global health are that doing so would (9) reduce the threat of infectious diseases to developed countries, (10) promote developed countries' economic interests, and (11) promote global security. All of these reasons count, and together they add up to make an overwhelmingly powerful case for change. Those opposed to wealthy government funding of developing world health improvement would most likely appeal, implicitly or explicitly to the idea that coercive taxation for redistributive purposes would violate the right of an individual to keep his hard-earned income. The idea that this reason not to improve global health should outweigh the combination of rights and values embodied in the eleven reasons enumerated above, however is implausibly extreme, morally repugnant and perhaps imprudent.

    Full Text Available Purpose. The volume of cargo transportation demands the introduction of a new generation of cars that would be able to provide all the needs of carriers. But this is impossible without the implementation of renovation repair facilities with the introduction of new technologies and modernization of the repair process. Repair of rolling stock is a key factor that must proceed with the establishment of new cars, as not all of the inventions may be repaired in car-repair depots, most of which are obsolete. The purpose is to analyze the possibility of increasing the efficiency of the repair process by introducing new repair technologies or improving the existing ones. It will improve not only the quality of the repair, but also its rate. Methodology. Works on improving the designs of freight cars are held by many design organizations in almost all industrialized countries. It makes repair organizations (depots and car-repair plants to upgrade the repair process. Achievements of-this goal is possible by improving the technology renovation and reorganization through the use of flexible flow technologies, which to date are the most effective in the repair of rolling stock. Findings. When performing the analysis it was determined that there are different designs of cars. More of cars are all-purpose and their repair does not cause difficulties for car-repair business. However, the number of specialized cars is also significant, and the technology of their repair should be improved. One of the reasons is that many models, such as tank wagons for the carriage of sulfur, are intended for the carriage of dangerous goods and their failure at the time of motion is not permitted. Originality. Firstly the authors have defined direction at improving technologies of repair specialized cars. Practical value. Actual improvement in the construction of cars is to improve the existing repair facilities. In addition, the repair technology using nowadays when repairing

  18. Training methods to improve vertical jump performance. (United States)

    Perez-Gomez, J; Calbet, J A L


    This study aims to review the main methods used to improve vertical jump performance (VJP). Although many training routines have been proposed, these can be grouped into four main categories: plyometric training (PT), weight training (WT), whole body vibration training (VT) and electromyostimulation training (ET). PT enhances muscular force, the rate of force development (RFD), muscular power, muscle contraction velocity, cross-sectional area (CSA), muscle stiffness allowing greater storage and release of elastic energy. WT improve muscular force, velocity, power output, and RFD during jumping on a force plate, muscle hypertrophy and neural adaptations. One of the most effective methods to improve VJP is the combination of PT with WT, which takes advantage of the enhancement of maximal dynamic force through WT and the positive effects of PT on speed and force of muscle contraction through its specific effect on type II fibers. Some authors have found an increase in VJP with the use of VT while other did not see such an effect. However, it remains unknown by which mechanisms VT could enhance VJP. ET has been shown to elicit muscle hypertrophy. The VJP may be improved when ET is applied concomitantly with PT or practice of sports. In summary, scientific evidence suggests that the best way to improve VJP is through the combination of PT with WT. Further research is needed to establish if better results are possible by more complex strategies.

    Full Text Available Listening is the first part of language skills that everyone gets when learning a language. It comes before speaking, reading, and writing. Meanwhile, most of the students get difficulty to learn listening of a foreign language, especially English. That is why shadowing was applied in the listening class as one of the solutions to make the learners of English listening easy to understand what the speaker says. This collaborative classroom action research was generally to know whether or not shadowing could improve the students listening skill. It was also specifically to know: (1 the lecturer’s activities, (2 the students’ activities, and (3 the students’ responses during the implementation of shadowing in the listening class. The subjects were 18 students of the third semester of English department of education faculty of Hasyim Asy’ari university (UNHASY Tebuireng Jombang in the academic year of 2016/2017. The data were obtained from the observations got from the notes written by the collaborator and the listening test. The students’ listening skill improved after the implementation of shadowing. It could be seen in the improvement of mean score, from 74.2 in cycle one to 75 in cycle two. Then, the precentage of students passing the minimum mastery criteria also improved, from 61% in cycle one to 77.8% in cycle two. Thus, it can be concluded that shadowing could improve students’ listening skill.

    We assess quantitatively the effect of exogenous health improvements on output per capita. Our simulation model allows for a direct effect of health on worker productivity, as well as indirect effects that run through schooling, the size and age-structure of the population, capital accumulation, and crowding of fixed natural resources. The model is parameterized using a combination of microeconomic estimates, data on demographics, disease burdens, and natural resource income in developing countries, and standard components of quantitative macroeconomic theory. We consider both changes in general health, proxied by improvements in life expectancy, and changes in the prevalence of two particular diseases: malaria and tuberculosis. We find that the effects of health improvements on income per capita are substantially lower than those that are often quoted by policy-makers, and may not emerge at all for three decades or more after the initial improvement in health. The results suggest that proponents of efforts to improve health in developing countries should rely on humanitarian rather than economic arguments. PMID:24347816

  2. Strategies for improving C4 photosynthesis. (United States)

    von Caemmerer, Susanne; Furbank, Robert T


    Recent activities to improve photosynthetic performance in crop plants has focused mainly on C3 photosynthesis where there are clear identified targets such as improving Rubisco kinetics, installation of a CO2 concentrating mechanism and alleviating limitations in chloroplast electron transport. Here we address strategies to improve photosynthetic performance in C4 plants, which utilize a CO2 concentrating mechanism, having evolved a complex blend of anatomy and biochemistry to achieve this. While the limitations to photosynthetic flux are not as well studied in C4 plants, work in transgenic Flaveria bidentis, a transformable model C4 dicot, and recent transcriptional analysis of leaves from diverse C4 plants, provides several gene candidates for improvement of carbon metabolism (such as pyruvate orthophosphate dikinase, phosphoenolpyruvate carboxylase and Rubisco) and for access of CO2 to phosphoenolpyruvate carboxylase in the mesophyll cells (such as carbonic anhydrase and CO2 porins). Chloroplast electron transport in C4 plants is shared between the two cell types, providing opportunities not only to alleviate limitations to flux through intersystem electron transport by targeting nuclear encoded proteins in the cytochrome (Cyt) b6/f complex, but in better sharing the harvesting of light energy between mesophyll and bundle sheath chloroplasts. Gene candidates for improvement of C4 photosynthesis could be utilized either through transgenic approaches or via mining natural allelic variation in sequenced populations of crop species.

  3. Demystifying theory and its use in improvement (United States)

    Davidoff, Frank; Dixon-Woods, Mary; Leviton, Laura; Michie, Susan


    The role and value of theory in improvement work in healthcare has been seriously underrecognised. We join others in proposing that more informed use of theory can strengthen improvement programmes and facilitate the evaluation of their effectiveness. Many professionals, including improvement practitioners, are unfortunately mystified—and alienated—by theory, which discourages them from using it in their work. In an effort to demystify theory we make the point in this paper that, far from being discretionary or superfluous, theory (‘reason-giving’), both informal and formal, is intimately woven into virtually all human endeavour. We explore the special characteristics of grand, mid-range and programme theory; consider the consequences of misusing theory or failing to use it; review the process of developing and applying programme theory; examine some emerging criteria of ‘good’ theory; and emphasise the value, as well as the challenge, of combining informal experience-based theory with formal, publicly developed theory. We conclude that although informal theory is always at work in improvement, practitioners are often not aware of it or do not make it explicit. The germane issue for improvement practitioners, therefore, is not whether they use theory but whether they make explicit the particular theory or theories, informal and formal, they actually use.

  4. Improving Accuracy of Processing Through Active Control

    Directory of Open Access Journals (Sweden)

    N. N. Barbashov


    Full Text Available An important task of modern mathematical statistics with its methods based on the theory of probability is a scientific estimate of measurement results. There are certain costs under control, and under ineffective control when a customer has got defective products these costs are significantly higher because of parts recall.When machining the parts, under the influence of errors a range scatter of part dimensions is offset towards the tolerance limit. To improve a processing accuracy and avoid defective products involves reducing components of error in machining, i.e. to improve the accuracy of machine and tool, tool life, rigidity of the system, accuracy of the adjustment. In a given time it is also necessary to adapt machine.To improve an accuracy and a machining rate there, currently  become extensively popular various the in-process gaging devices and controlled machining that uses adaptive control systems for the process monitoring. Improving the accuracy in this case is compensation of a majority of technological errors. The in-cycle measuring sensors (sensors of active control allow processing accuracy improvement by one or two quality and provide a capability for simultaneous operation of several machines.Efficient use of in-cycle measuring sensors requires development of methods to control the accuracy through providing the appropriate adjustments. Methods based on the moving average, appear to be the most promising for accuracy control since they include data on the change in some last measured values of the parameter under control.

  5. Improving STEM Student Learning Outcomes with GIS (United States)

    Montgomery, W. W.


    Longitudinal data collection initiated a decade ago as part of a successful NSF-CCLI grant proposal has resulted in a large - and growing - sample (200+) of students who report on their perceptions of self-improvement in Technology, Critical Thinking, and Quantitative Reasoning proficiencies upon completion of an introductory (200-level) GIS course at New Jersey City University, a Hispanic-Serving and Minority Institution in Jersey City, NJ. Results from student satisfaction surveys indicate that, not surprisingly, 80% of respondents report improved confidence in Technology Literacy. Critical Thinking proficiency is judged to be significantly improved by 60% of respondents. On the other hand, Quantitative Reasoning proficiency confidence is improved in only 30% of students. This latter finding has prompted the instructor to search for more easily recognizable (to the student) ways of embedding quantitative reasoning into the course, as it is obvious to any GIS professional that there is an enormous amount of quantitative reasoning associated with this technology. A second post-course questionnaire asks students to rate themselves in these STEM proficiency areas using rubrics. Results mirror those from the self-satisfaction surveys. On a 5-point Likkert scale, students tend to see themselves improving about one letter grade on average in each proficiency area. The self-evaluation rubrics are reviewed by the instructor and are judged to be accurate for about 75% of the respondents.

  6. Improved models of dense anharmonic lattices

    Energy Technology Data Exchange (ETDEWEB)

    Rosenau, P., E-mail:; Zilburg, A.


    We present two improved quasi-continuous models of dense, strictly anharmonic chains. The direct expansion which includes the leading effect due to lattice dispersion, results in a Boussinesq-type PDE with a compacton as its basic solitary mode. Without increasing its complexity we improve the model by including additional terms in the expanded interparticle potential with the resulting compacton having a milder singularity at its edges. A particular care is applied to the Hertz potential due to its non-analyticity. Since, however, the PDEs of both the basic and the improved model are ill posed, they are unsuitable for a study of chains dynamics. Using the bond length as a state variable we manipulate its dispersion and derive a well posed fourth order PDE. - Highlights: • An improved PDE model of a Newtonian lattice renders compacton solutions. • Compactons are classical solutions of the improved model and hence amenable to standard analysis. • An alternative well posed model enables to study head on interactions of lattices' solitary waves. • Well posed modeling of Hertz potential.

  7. Proteomics: A Biotechnology Tool for Crop Improvement

    Directory of Open Access Journals (Sweden)

    Moustafa eEldakak


    Full Text Available A sharp decline in the availability of arable land and sufficient supply of irrigation water along with a continuous steep increase in food demands have exerted a pressure on farmers to produce more with fewer resources. A viable solution to release this pressure is to speed up the plant breeding process by employing biotechnology in breeding programs. The majority of biotechnological applications rely on information generated from various -omic technologies. The latest outstanding improvements in proteomic platforms and many other but related advances in plant biotechnology techniques offer various new ways to encourage the usage of these technologies by plant scientists for crop improvement programs. A combinatorial approach of accelerated gene discovery through genomics, proteomics, and other associated -omic branches of biotechnology, as an applied approach, is proving to be an effective way to speed up the crop improvement programs worldwide. In the near future, swift improvements in -omic databases are becoming critical and demand immediate attention for the effective utilization of these techniques to produce next-generation crops for the progressive farmers. Here, we have reviewed the recent advances in proteomics, as tools of biotechnology, which are offering great promise and leading the path towards crop improvement for sustainable agriculture.

  8. Idaho Chemical Processing Plant Process Efficiency improvements

    Energy Technology Data Exchange (ETDEWEB)

    Griebenow, B.


    In response to decreasing funding levels available to support activities at the Idaho Chemical Processing Plant (ICPP) and a desire to be cost competitive, the Department of Energy Idaho Operations Office (DOE-ID) and Lockheed Idaho Technologies Company have increased their emphasis on cost-saving measures. The ICPP Effectiveness Improvement Initiative involves many activities to improve cost effectiveness and competitiveness. This report documents the methodology and results of one of those cost cutting measures, the Process Efficiency Improvement Activity. The Process Efficiency Improvement Activity performed a systematic review of major work processes at the ICPP to increase productivity and to identify nonvalue-added requirements. A two-phase approach was selected for the activity to allow for near-term implementation of relatively easy process modifications in the first phase while obtaining long-term continuous improvement in the second phase and beyond. Phase I of the initiative included a concentrated review of processes that had a high potential for cost savings with the intent of realizing savings in Fiscal Year 1996 (FY-96.) Phase II consists of implementing long-term strategies too complex for Phase I implementation and evaluation of processes not targeted for Phase I review. The Phase II effort is targeted for realizing cost savings in FY-97 and beyond.

  9. Technology in Arthroplasty: Are We Improving Value? (United States)

    Waddell, Bradford S; Carroll, Kaitlin; Jerabek, Seth


    Total joint arthroplasty is regarded as a highly successful procedure. Patient outcomes and implant longevity, however, are related to proper alignment and position of the prostehses. In an attempt to reduce outliers and improve accuracy and precision of component position, navigation and robotics have been introduced. These technologies, however, come at a price. The goals of this review are to evaluate these technologies in total joint arthroplasty and determine if they add value. Recent studies have demonstrated that navigation and robotics in total joint arthroplasty can decrease outliers while improving accuracy in component positioning. While some studies have demonstrated improved patient reported outcomes, not all studies have shown this to be true. Most studies cite increased cost of equipment and longer operating room times as the major downsides of the technologies at present. Long-term studies are just becoming available and are promising, as some studies have shown decreased revision rates when navigation is used. Finally, there are relatively few studies evaluating the direct cost and value of these technologies. Navigation and robotics have been shown to improve component position in total joint arthroplasty, which can improve patient outcomes and implant longevity. These technologies offer a promising future for total joint arthroplasty.

  10. Engaging Clinical Nurses in Quality Improvement Projects. (United States)

    Moore, Susan; Stichler, Jaynelle F


    Clinical nurses have the knowledge and expertise required to provide efficient and proficient patient care. Time and knowledge deficits can prevent nurses from developing and implementing quality improvement or evidence-based practice projects. This article reviews a process for professional development of clinical nurses that helped them to define, implement, and analyze quality improvement or evidence-based practice projects. The purpose of this project was to educate advanced clinical nurses to manage a change project from inception to completion, using the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) Change Acceleration Process as a framework. One-to-one mentoring and didactic in-services advanced the knowledge, appreciation, and practice of advanced practice clinicians who completed multiple change projects. The projects facilitated clinical practice changes, with improved patient outcomes; a unit cultural shift, with appreciation of quality improvement and evidence-based projects; and engagement with colleagues. Project outcomes were displayed in poster presentations at a hospital exposition for knowledge dissemination. Copyright 2015, SLACK Incorporated.

  11. Photovoltaic Czochralski silicon manufacturing technology improvements (United States)

    Jester, T.


    This report describes work performed under a three-year, three-phase, cost-share contract to demonstrate significant cost reductions and improvements in manufacturing technology. The objective of the program is to reduce costs in photovoltaic manufacturing by approximately 10% per year. The work was focused in three main areas: (1) silicon crystal growth and thin wafer technology; (2) silicon cell processing; and (3) silicon module fabrication and environmental, safety, and health issues. During this reporting period, several significant improvements were achieved. The crystal growing operation improved significantly with an increase in growth capacity due to larger crucibles, higher polysilicon packing density, and high pull speeds. Wafer processing with wire saws progressed rapidly, and the operation is completely converted to wire saw wafer processing. The wire saws yield almost 50% more wafers per inch in production, thus improving manufacturing volume by 50% without any additional expense in crystal growth. Cell processing improvements focused on better understanding the contact paste and firing processes. Module designs for lower material and labor costs began with the focus on a new junction box, larger modules with larger cells, and a less costly framing technique. In addition, chlorofluorocarbon (CFC) usage was completely eliminated in the Siemens manufacturing facility during this period, resulting in significant reductions in the cost of caustic waste treatment.

  12. Improvement of Parallel Algorithm for MATRA Code

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Seong-Jin; Seo, Kyong-Won; Kwon, Hyouk; Hwang, Dae-Hyun [Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)


    The feasibility study to parallelize the MATRA code was conducted in KAERI early this year. As a result, a parallel algorithm for the MATRA code has been developed to decrease a considerably required computing time to solve a bigsize problem such as a whole core pin-by-pin problem of a general PWR reactor and to improve an overall performance of the multi-physics coupling calculations. It was shown that the performance of the MATRA code was greatly improved by implementing the parallel algorithm using MPI communication. For problems of a 1/8 core and whole core for SMART reactor, a speedup was evaluated as about 10 when the numbers of used processor were 25. However, it was also shown that the performance deteriorated as the axial node number increased. In this paper, the procedure of a communication between processors is optimized to improve the previous parallel algorithm.. To improve the performance deterioration of the parallelized MATRA code, the communication algorithm between processors was newly presented. It was shown that the speedup was improved and stable regardless of the axial node number.

  13. Improved Chromatographic Techniques for Sulfur Pollutants (United States)

    Hartmann, C. H.


    This paper describes several improvements in instrumental techniques for the analysis of low ppb concentrations of sulfur gases using gas chromatography (G.C.). This work has focused on the analytical problem of ambient air monitoring of the two main sulfur gas pollutants, hydrogen sulfide and sulfur dioxide. The most significant technical improvement that will be reported here is the newly developed silica gel column for ppb concentrations of the light sulfur gases (COS, H2S, CS2, SO2, CH3SH). A simplified inlet system will be described which improves reliability of the GC system. The flame photometric detector is used as the means of selectively and sensitively detecting the low concentrations of sulfur gases. Improvements will be described which have yielded better performance than previously reported for this application of the detector. Also included in this paper will be a report of field monitoring using this improved GC system. Reliability and repeatability of performance at the low ppb concentrations of sulfur gases will be demonstrated.

  14. An improved quantum key distribution protocol (United States)

    Wu, Ting-wan; Wu, Guo-hua


    This paper presented an improved quantum key distribution protocol of the quantum cryptology. Using the same measure polarizer as BB84 protocol, the improved protocol we designed with not any classical channel, but a new looped quantum channel instead, so the job of sending and receiving can be finished only by one same person. It brings several good points: the utilization ratio of photons 100% in perfect condition, at least twice over other protocols, or even higher; the public channel easy to be attacked is avoided. Further, the improved protocol authenticates the legal communicators with pre-share information, so that no attacker can jump over the progress of authentication. Be alien from the protocol of BB84, the improved protocol uses message summary to detect whether messages intercepted by attacker. Because the message summary is encrypted by one-time-pad method using pre-share information, attacker could not alter the message summary and that not to be discovered. Moreover, some theoretical analysis to the improved protocol given with information theory: we used the measure channel concept for quantum detection, and calculated the information quantity obtained by attacker in the quantum secrecy communication. The analysis results provide the theory criterion for the legal communicators and the attackers.

    The continuous evolution and improvement of safety-related processes has included the analysis, design and development of training plans for the qualification of maintenance nuclear power plant personnel. In this respect, the international references in this area recommend the establishment of systematic qualification programmes for personnel performing functions or carrying out safety related tasks. Maintenance personnel qualification processes have improved significantly, and training plans have been designed and developed based on Systematic Approach to Training methodology to each job position. These improvements have been clearly reflected in recent training programmes with new training material and training facilities focused not only on developing technical knowledge and skills but also on improving attitudes and safety culture. The objectives of maintenance training facilities such as laboratories, mock-ups real an virtual, hydraulic loops, field simulators and other training material to be used in the maintenance training centre are to cover training necessities for initial and continuous qualification. Evidently, all these improvements made in the qualification of plant personnel should be extended to include supplemental personnel (external or contracted) performing safety-related tasks. The supplemental personnel constitute a very spread group, covering the performance of multiple activities entailing different levels of responsibility. Some of these activities are performed permanently at the plant, while others are occasional or sporadic. In order to establish qualification requirements for these supplemental workers, it is recommended to establish a rigorous analysis of job positions and tasks. The objective will be to identify the qualification requirements to assure competence and safety. (authors)

    This patent relates to an improvement in the bismuth phosphate process for separating and recovering plutonium from neutron irradiated uranium, resulting in improved decontamination even without the use of scavenging precipitates in the by-product precipitation step and subsequently more complete recovery of the plutonium in the product precipitation step. This improvement is achieved by addition of fluomolybdic acid, or a water soluble fluomolybdate, such as the ammonium, sodium, or potassium salt thereof, to the aqueous nitric acid solution containing tetravalent plutonium ions and contaminating fission products, so as to establish a fluomolybdate ion concentration of about 0.05 M. The solution is then treated to form the bismuth phosphate plutonium carrying precipitate.

    Directory of Open Access Journals (Sweden)

    Li Fangwei


    Full Text Available In order to reflect the situation of network security assessment performance fully and accurately, a new network security situation awareness model based on information fusion was proposed. Network security situation is the result of fusion three aspects evaluation. In terms of attack, to improve the accuracy of evaluation, a situation assessment method of DDoS attack based on the information of data packet was proposed. In terms of vulnerability, a improved Common Vulnerability Scoring System (CVSS was raised and maked the assessment more comprehensive. In terms of node weights, the method of calculating the combined weights and optimizing the result by Sequence Quadratic Program (SQP algorithm which reduced the uncertainty of fusion was raised. To verify the validity and necessity of the method, a testing platform was built and used to test through evaluating 2000 DAPRA data sets. Experiments show that the method can improve the accuracy of evaluation results.

  19. Improvements in inservice testing regulatory guidance

    Energy Technology Data Exchange (ETDEWEB)

    Campbell, P.L.


    Over the last few years, the NRC has issued guidance to licensees toward improving the quality of requests for relief or alternatives to the code requirements and bring some measure of consistency to the implementation of the code requirements. Based on the majority of the recent submittals, the overall quality has improved. If all of the steps in the internal process for responding to the requests are timely, the review of an updated program can be completed in six to nine months. When a single or only a few requests are submitted, the staff is generally able to complete an evaluation in less than three months. When schedules are related to outages or exigent circumstances, the NRC responds accordingly. The improvements in schedules can be attributed to publication of staff guideline documents, licensees` efforts in preparing more complete descriptions and justification and an increase in the number of NRC technical staff reviewers assigned to IST.

  20. Body esteem improves after bariatric surgery. (United States)

    Madan, Atul K; Beech, Bettina M; Tichansky, David S


    Body esteem is an issue for the morbidly obese. Although the primary goal of bariatric surgery is to improve, cure, and prevent medical comorbidities, the psychological aspect of bariatric surgery is just as important. Few studies have investigated the body esteem of patients after laparoscopic gastric bypass. This investigation tested the hypothesis that body esteem improves after bariatric surgery. Preoperative and postoperative patients were asked to fill out an institutional review board-exempted survey that included the Body-Esteem Scale for Adolescents and Adults (BESAA). The subscales include Appearance, Weight, and Attribution. Postoperative patients were told to fill the BESAA as they felt currently and as they felt before surgery. They felt that they had better scores currently than before surgery. Preoperative patients had worse scores than postoperative patients. As in many medical issues, body esteem improves after bariatric surgery. When discussing its benefits, psychological aspects of body esteem should be touted as well.

  2. Improving calorimeter resolution using temperature compensation calculations (United States)

    Smiga, Joseph; Purschke, Martin


    The sPHENIX experiment is an upgrade of the existing PHENIX apparatus at the Relativistic Heavy-Ion Collider (RHIC). The new detector improves upon measurements of various physical processes, such as jets of particles created during heavy-ion collisions. Prototypes of various calorimeter components were tested at the Fermilab Test Beam Facility (FTBF). This analysis tries to compensate the effects of temperature drifts in the silicon photomultipliers (SiPMs). Temperature data were used to calculate an appropriate compensation factor. This analysis will improve the achievable resolution and will also determine how accurately the temperature must be controlled in the final experiment. This will improve the performance of the calorimeters in the sPHENIX experiment. This project was supported in part by the U.S. Department of Energy, Office of Science, Office of Workforce Development for Teachers and Scientists (WDTS) under the Science Undergraduate Laboratory Internships Program (SULI).

  3. Improved silicon nitride for advanced heat engines (United States)

    Yeh, Harry C.; Fang, Ho T.


    The results of a four year program to improve the strength and reliability of injection-molded silicon nitride are summarized. Statistically designed processing experiments were performed to identify and optimize critical processing parameters and compositions. Process improvements were monitored by strength testing at room and elevated temperatures, and microstructural characterization by optical, scanning electron microscopes, and scanning transmission electron microscope. Processing modifications resulted in a 20 percent strength and 72 percent Weibull slope improvement of the baseline material. Additional sintering aids screening and optimization experiments succeeded in developing a new composition (GN-10) capable of 581.2 MPa at 1399 C. A SiC whisker toughened composite using this material as a matrix achieved a room temperature toughness of 6.9 MPa m(exp .5) by the Chevron notched bar technique. Exploratory experiments were conducted on injection molding of turbocharger rotors.

    Kennedy, Denise M; Nordrum, Jon T; Edwards, Frederick D; Caselli, Richard J; Berry, Leonard L


    A framework for improving health care service quality was implemented at a 12-provider family medicine practice in 2010. A national patient satisfaction research vendor conducted weekly telephone surveys of 840 patients served by that practice: 280 patients served in 2009, and 560 served during 2010 and 2011. After the framework was implemented, the proportion of "excellent" ratings of provider service (the highest rating on a 5-point scale) increased by 5% to 9%, most notably thoroughness (P = .04), listening (P = .04), and explaining (P = .04). Other improvements included prompt test result notification and telephone staff courtesy (each by 10%, P = .02), as well as teamwork (by 8%, P = .04). Overall quality increased by 10% (P = .01), moving the practice from the 68th to the 91st percentile of medical practices in the research vendor's database. Improvements in patient satisfaction suggest that this framework may be useful in value-based payment models. © 2014 by the American College of Medical Quality.

  7. Improving decoy databases for protein folding algorithms

    KAUST Repository

    Lindsey, Aaron


    Copyright © 2014 ACM. Predicting protein structures and simulating protein folding are two of the most important problems in computational biology today. Simulation methods rely on a scoring function to distinguish the native structure (the most energetically stable) from non-native structures. Decoy databases are collections of non-native structures used to test and verify these functions. We present a method to evaluate and improve the quality of decoy databases by adding novel structures and removing redundant structures. We test our approach on 17 different decoy databases of varying size and type and show significant improvement across a variety of metrics. We also test our improved databases on a popular modern scoring function and show that they contain a greater number of native-like structures than the original databases, thereby producing a more rigorous database for testing scoring functions.

    Ejrnæs, Mette; Persson, Karl Gunnar


    This article looks at the gains from improved market efficiency in long-distance grain trade in the second half of the nineteenth century, when violations of the law of one price were reduced due to improved information transmission. Two markets, a major export centre, Chicago, and a major importer......, Liverpool, are analysed. We show that the law of one price equilibrium was an ‘attractor equilibrium'. The implication is that prices converged to that equilibrium in a tâtonnement process. Because of asymmetrically timed information between markets separated by long distances there were periods of excess...... demand as well as excess supply, which triggered off the tâtonnement process. Over time, adjustments to equilibrium, as measured by the half-life of a shock, became faster and violations of the law of one price become smaller. There were significant gains from improved market efficiency, which took place...

  11. The benefits of improved national elevation data (United States)

    Snyder, Gregory I.


    This article describes how the National Enhanced Elevation Assessment (NEEA) has identified substantial benefits that could come about if improved elevation data were publicly available for current and emerging applications and business uses such as renewable energy, precision agriculture, and intelligent vehicle navigation and safety. In order to support these diverse needs, new national elevation data with higher resolution and accuracy are needed. The 3D Elevation Program (3DEP) initiative was developed to meet the majority of these needs and it is expected that 3DEP will result in new, unimagined information services that would result in job growth and the transformation of the geospatial community. Private-sector data collection companies are continuously evolving sensors and positioning technologies that are needed to collect improved elevation data. An initiative of this scope might also provide an opportunity for companies to improve their capabilities and produce even higher data quality and consistency at a pace that might not have otherwise occurred.

  12. Power theories for improved power quality

    CERN Document Server

    Pasko, Marian


    Power quality describes a set of parameters of electric power and the load’s ability to function properly under specific conditions. It is estimated that problems relating to power quality costs the European industry hundreds of billions of Euros annually. In contrast, financing for the prevention of these problems amount to fragments of these costs. Power Theories for Improved Power Quality addresses this imbalance by presenting and assessing a range of methods and problems related to improving the quality of electric power supply. Focusing particularly on active compensators and the DSP based control algorithms, Power Theories for Improved Power Quality introduces the fundamental problems of electrical power. This introduction is followed by chapters which discuss: •‘Power theories’ including their historical development and application to practical problems, •operational principles of active compensator’s DSP control based algorithms using examples and results from laboratory research, and •t...

  13. Improving EHR Usability Using LEAN Methodology. (United States)

    Bosse, Corbin; Kelly, Kandace


    Electronic health record (EHR) usability concerns continue to reduce EHR effectiveness. LEAN methodology, which focuses on waste elimination, may provide an effective method to address efficiency related usability deficiencies. We aimed to improve the usability of an inpatient seclusion and restraint (SR) EHR module using LEAN methodology. A multidisciplinary team convened to evaluate and redesign clinical and technological SR workflows using LEAN techniques, including process mapping and time-series analyses. SR module modifications addressed 40 of the 60 efficiency related usability deficiencies identified in the initial SR module. Usability enhancements included elimination of 10 nonessential inputs, 21 redundancies, and nine overhead functions. Process steps were reduced from 74 to 47. Improving EHR usability is critical to assure safe, effective, and efficient care1. We demonstrated that LEAN methodology is an effective method to address efficiency related EHR usability deficiencies. More research is needed to determine how these improvements impact care quality.

  14. Integrating empowerment evaluation and quality improvement to achieve healthcare improvement outcomes (United States)

    Wandersman, Abraham; Alia, Kassandra Ann; Cook, Brittany; Ramaswamy, Rohit


    While the body of evidence-based healthcare interventions grows, the ability of health systems to deliver these interventions effectively and efficiently lags behind. Quality improvement approaches, such as the model for improvement, have demonstrated some success in healthcare but their impact has been lessened by implementation challenges. To help address these challenges, we describe the empowerment evaluation approach that has been developed by programme evaluators and a method for its application (Getting To Outcomes (GTO)). We then describe how GTO can be used to implement healthcare interventions. An illustrative healthcare quality improvement example that compares the model for improvement and the GTO method for reducing hospital admissions through improved diabetes care is described. We conclude with suggestions for integrating GTO and the model for improvement. PMID:26178332

    Few studies have demonstrated improvement in adherence to Pediatric Advanced Life Support guidelines for severe sepsis and septic shock. We sought to improve adherence to national guidelines for children with septic shock in a pediatric emergency department with poor guideline adherence. Prospective cohort study of children presenting to a tertiary care pediatric emergency department with septic shock. Quality improvement (QI) interventions, including repeated plan-do-study-act cycles, were used to improve adherence to a 5-component sepsis bundle, including timely (1) recognition of septic shock, (2) vascular access, (3) administration of intravenous (IV) fluid, (4) antibiotics, and (5) vasoactive agents. The intervention focused on IV fluid delivery as a key driver impacting bundle adherence, and adherence was measured using statistical process control methodology. Two-hundred forty-two patients were included: 126 subjects before the intervention (November 2009 to March 2011), and 116 patients during the QI intervention (October 2011 to May 2013). We achieved 100% adherence for all metrics, including (1) administration of 60 mL/kg IV fluid within 60 minutes (increased from baseline adherence rate of 37%), (2) administration of vasoactive agents within 60 minutes (baseline rate of 35%), and (3) 5-component bundle adherence (baseline rate of 19%). Improvement was sustained over 9 months. The number of septic shock cases between each death from this condition increased after implementation of the QI intervention. Using QI methodology, we have demonstrated improved adherence to national guidelines for severe sepsis and septic shock. Copyright © 2014 by the American Academy of Pediatrics.

  16. Improving fluid balance monitoring on the wards. (United States)

    Jeyapala, Sobanakumari; Gerth, Alice; Patel, Aarti; Syed, Nazia


    Clinical experience and nursing metrics have consistently identified poor documentation of fluid balance monitoring at Milton Keynes University Hospital, compromising patient safety and quality of care. This project aimed to increase the percentage of fluid balance charts correctly completed on the wards. Three areas for improvement were identified: understanding the importance of good fluid balance monitoring, correct identification of patients requiring monitoring, and ease of completion of fluid balance charts. Three interventions were deployed on two acute medical awards in consecutive cycles; 1) small group education for staff, 2) creation of board magnets to aid the multidisciplinary team to identify patients requiring monitoring, 3) modification of the current fluid balance chart. Questionnaires were utilised to highlight improvements with current charts and measured staff awareness pre and post education. Each intervention was implemented for one week followed by daily surveys for four days to monitor compliance. Initial results showed a range of 6-12 charts used daily per ward. Of these 0-45% of them were correctly filled. Post education there was a reduced number of inappropriate charts. Introduction of board magnets improved correlation between doctors and nurses in identification of patients (52% before, 77% after magnets). Following modification there was a subjective improvement in the quality of chart completion. This study highlighted that understanding and use of fluid balance monitoring can be improved for nurses, health care assistants (HCAs), and doctors. These improvements allow better documentation and safer patient care. As a result, Milton Keynes University Hospital is investing in magnets and modified charts for a Trust-wide pilot.

    European wildfires are a seasonal natural hazard that many regions must battle regularly. However, as European urbanization continues to encroach on natural areas and the climate changes it is likely that the frequency of wildfires will increase likewise the number of areas prone to wildfires. It is therefore paramount not only to increase public awareness of this natural hazard but also to be prepared by improving wildfire hazard forecasting, monitoring, and mapping. As part of the H2020 funded project entitled Improving Resilience to Emergencies through Advanced Cyber Technologies: I-REACT (Grant Agreement #700256) , there is a task with the goal to develop models and implement technologies to improve the support around the entire emergency management cycle with respect to wildfire hazards. Based on operational weather forecasts, pan-European geospatial data as well as regularly acquired Earth Observation imagery through the Copernicus program, and other sources of information such as social media channels a European wildfire service is being developed. This will be achieved by improving on the successes of the European Forest Fire Information Service (EFFIS) and the guidance of emergency managers experienced in wildfire hazards. Part of the research will be to reduce the number of false alarms. However, once a wildfire has been identified, the system focuses on the disaster region to provide situational information to the decision makers applying state-of-the-art approaches to improve disaster response. Post-wildfire information will continue to be produced for damage and recovery assessments. Ultimately, I-REACT expects to reduce wildfire costs to life, property and livelihood. This work will improve wildfire disaster emergency management through the development and integration of new data and technologies respectively as well as the knowledge from emergency managers who not only understand the hazard itself but also can provide insights into the information

  18. Powerplant productivity improvements and regulatory incentives

    Energy Technology Data Exchange (ETDEWEB)

    Hardy, D; Brown, D


    The purpose of this study was to examine the benefits to be gained from increased powerplant productivity and to validate and demonstrate the use of incentives within the regulatory process to promote the improvement of powerplant productivity. The system-wide costs savings to be gained from given productivity improvement scenarios are estimated in both the short and long term. Numerous reports and studies exist which indicate that productivity improvements at the powerplant level are feasible and cost effective. The efforts of this study widen this focus and relate system-wide productivity improvements with system-wide cost savings. The initial thrust of the regulatory section of this study is to validate the existence of reasonable incentive procedures which would enable regulatory agencies to better motivate electric utilities to improve productivity on both the powerplant and system levels. The voluntary incentive format developed in this study was designed to facilitate the link between profit and efficiency which is typically not clear in most regulated market environments. It is concluded that at the present time, many electric utilities in this country could significantly increase the productivity of their base load units, and the adoption of an incentive program of the general type recommended in this study would add to rate of return regulation the needed financial incentives to enable utilities to make such improvements without losing long-run profit. In light of the upcoming oil import target levels and mandatory cutbacks of oil and gas as boiler fuels for electric utilities, the use of incentive programs to encourage more efficient utilization of coal and nuclear base load capacity will become far more inviting over the next two decades.

    Rattlesnake is a MOOSE-based radiation transport application developed at INL to support modern multi-physics simulations. At the beginning of the last year, Rattlesnake was able to perform steady-state, transient and eigenvalue calculations for the multigroup radiation transport equations. Various discretization schemes, including continuous finite element method (FEM) with discrete ordinates method (SN) and spherical harmonics expansion method (PN) for the self-adjoint angular flux (SAAF) formulation, continuous FEM (CFEM) with SN for the least square (LS) formulation, diffusion approximation with CFEM and discontinuous FEM (DFEM), have been implemented. A separate toolkit, YAKXS, for multigroup cross section management was developed to support Rattlesnake calculations with feedback both from changes in the field variables, such as fuel temperature, coolant density, and etc., and in isotope inventory. The framework for doing nonlinear diffusion acceleration (NDA) within Rattlesnake has been set up, and both NDA calculations with SAAF-SN-CFEM scheme and Monte Carlo with OpenMC have been performed. It was also used for coupling BISON and RELAP-7 for the full-core multiphysics simulations. Within the last fiscal year, significant improvements have been made in Rattlesnake. Rattlesnake development was migrated into our internal GITLAB development environment at the end of year 2014. Since then total 369 merge requests has been accepted into Rattlesnake. It is noted that the MOOSE framework that Rattlesnake is based on is under continuous developments. Improvements made in MOOSE can improve the Rattlesnake. It is acknowledged that MOOSE developers spent efforts on patching Rattlesnake for the improvements made on the framework side. This report will not cover the code restructuring for better readability and modularity and documentation improvements, which we have spent tremendous effort on. It only details some of improvements in the following sections.

    Many developing countries use food-price subsidies or controls to improve nutrition. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute towards foods with higher non-nutritional attributes (e.g., taste), but lower nutritional content per unit of currency, weakening or perhaps even reversing the subsidy's intended impact. We analyze data from a randomized program of large price subsidies for poor households in two provinces of China and find no evidence that the subsidies improved nutrition. In fact, it may have had a negative impact for some households. (JEL I38; O12; Q18).

    The scale and complexity of change in software process improvement (SPI) are considerable and managerial attention to organizational culture during SPI can therefore potentially contribute to successful outcomes. However, we know little about the impact of variations in organizational subculture...... CMMI level 2 as planned, ASY struggled to implement even modest improvements. To explain these differences, we analyzed the underlying organizational culture within ISY and ASY using two different methods for subculture assessment. The study demonstrates how variations in culture across software...... organizations can have important implications for SPI outcomes. Furthermore, it provides insights into how software managers can practically assess subcultures to inform decisions about and help prepare plans for SPI initiatives....

    Bursa, Francis; Henty, David; Kerrane, Eoin; Lucini, Biagio; Patella, Agostino; Pica, Claudio; Pickup, Thomas; Rago, Antonio


    We present a numerical study of spectroscopic observables in the SU(2) gauge theory with two adjoint fermions using improved source and sink operators. We compare in detail our improved results with previous determinations of masses that used point sources and sinks and we investigate possible systematic effects in both cases. Such comparison enables us to clearly assess the impact of a short temporal extent on the physical picture, and to investigate some effects due to the finite spatial box. While confirming the IR-conformal behaviour of the theory, our investigation shows that in order to make firm quantitative predictions, a better handle on finite size effects is needed.

  6. Measures for energy efficiency improvement of buildings

    Directory of Open Access Journals (Sweden)

    Vukadinović Ana V.


    Full Text Available The increase in energy consumption in buildings causes the need to propose energy efficiency improvement measures. Urban planning in accordance with micro location conditions can lead to energy consumption reduction in buildings through the passive solar design. While satisfying the thermal comfort to the user space purpose, energy efficiency can be achieved by optimizing the architectural and construction parameters such as shape of the building, envelope structure and the percentage of glazing. The improvement of the proposed measures, including the use of renewable energy sources, can meet requirements of Directive 2010/31 / EU of 'nearly zero energy buildings'.

    Lou, Guohuan; Xu, Ran; Yang, Chunming


    For currently existed problems and difficulties during the small and medium enterprises use EPC (Electronic Product Code) ALE (Application Level Events) specification to achieved middleware, based on the analysis of principle of EPC Middleware, an improved design method for EPC middleware is presented. This method combines the powerful function of MySQL database, uses database to connect reader-writer with upper application system, instead of development of ALE application program interface to achieve a middleware with general function. This structure is simple and easy to implement and maintain. Under this structure, different types of reader-writers added can be configured conveniently and the expandability of the system is improved.

    Anaerobic digestion improvement can be accomplished by different methods. Besides optimization of process conditions is frequently used pretreatment of input sludge and increase of process temperature. Thermophilic process brings a higher solids reduction and biogas production, the high resistance to foaming, no problems with odour, the higher effect of destroying pathogens and the improvement of the energy balance of the whole treatment plant. Disintegration of excess activated sludge in lysate centrifuge was proved in full-scale conditions causing increase of biogas production. The rapid thermal conditioning of digested sludge is acceptable method of particulate matter disintegration and solubilization. (author)

  11. Infection prevention and control practitioners: improving engagement. (United States)

    Aziz, Ann-Marie

    Every healthcare worker plays a vital part in minimising the risk of cross infection. Infection prevention and control (IPC) practitioners have the skills and competencies to assist organisations in improving engagement among staff and play a vital part in achieving this. IPC practitioners have skills in clinical practice, education, research and leadership, and these skills ensure high-quality care for patients and support strategies for engaging staff. This article highlights how IPC practitioners' skills and competencies are required for preventing infection and improving staff engagement. Engaged staff generate positive outcomes for both patients and staff, which is a welcome result for all healthcare organisations.

  13. Improving analytical tomographic reconstructions through consistency conditions

    CERN Document Server

    Arcadu, Filippo; Stampanoni, Marco; Marone, Federica


    This work introduces and characterizes a fast parameterless filter based on the Helgason-Ludwig consistency conditions, used to improve the accuracy of analytical reconstructions of tomographic undersampled datasets. The filter, acting in the Radon domain, extrapolates intermediate projections between those existing. The resulting sinogram, doubled in views, is then reconstructed by a standard analytical method. Experiments with simulated data prove that the peak-signal-to-noise ratio of the results computed by filtered backprojection is improved up to 5-6 dB, if the filter is used prior to reconstruction.

  16. Improving plasmonic waveguides coupling efficiency using nanoantennas

    DEFF Research Database (Denmark)

    Andryieuski, Andrei; Malureanu, Radu; Bouillard, Jean-Sebastien


    Plasmonic waveguides bear a lot of potential for photonic applications. However, one of the challenges for implementing them in devices is the low coupling efficiency to and from optical fibers. We report on our approach to facilitate the coupling efficiency with the use of metallic nanoantennas....... The classical dipole antenna scheme can be improved by changing the nanoantenna geometry, adding constructive elements such as reflecting bars and mirrors and using arrays of antennas. The modelling designates that the coupling efficiency from a vertical fiber to a plasmonic waveguide can be improved more than...

    Xiao, Su; Shiloach, Joseph; Betenbaugh, Michael J


    Cellular engineering of bacteria, fungi, insect cells and mammalian cells is a promising methodology to improve recombinant protein production for structural, biochemical, and commercial applications. Increased understanding of the host organism biology has suggested engineering strategies targeting bottlenecks in transcription, translation, protein processing and secretory pathways, as well as cell growth and survival. A combination of metabolic engineering and synthetic biology has been used to improve the properties of cells for protein production, which has resulted in enhanced yields of multiple protein classes.

    Full Text Available This paper discusses the concept of continuous improvement (CI by looking beyond what traditionally highlighted in literature concerning continuous improvement or Total Quality Management (TQM. The primary argument put forwarded in the discussion is that despite the undeniable positive results from CI practices, the way these activities are implemented, however, will lead to most programs becoming self-limiting. It needs to be asserted here that this paper is not intended to despise CI, rather, its purpose is limited only to provide a balance on the prevailing positive views toward CI.
