    Evaluating whole slide images of histological and cytological samples is used in pathology for diagnostics, grading and prognosis . It is often necessary to rescale whole slide images of a very large size. Image resizing is one of the most common applications of interpolation. We collect the advantages and drawbacks of nine interpolation methods, and as a result of our analysis, we try to select one interpolation method as the preferred solution. To compare the performance of interpolation methods, test images were scaled and then rescaled to the original size using the same algorithm. The modified image was compared to the original image in various aspects. The time needed for calculations and results of quantification performance on modified images were also compared. For evaluation purposes, we used four general test images and 12 specialized biological immunohistochemically stained tissue sample images. The purpose of this survey is to determine which method of interpolation is the best to resize whole slide images, so they can be further processed using quantification methods. As a result, the interpolation method has to be selected depending on the task involving whole slide images. © 2016 The Authors Journal of Microscopy © 2016 Royal Microscopical Society.

  2. Observer Based Sliding Mode Attitude Control: Theoretical and Experimental Results

    Full Text Available In this paper we present the design of a sliding mode controller for attitude control of spacecraft actuated by three orthogonal reaction wheels. The equilibrium of the closed loop system is proved to be asymptotically stable in the sense of Lyapunov. Due to cases where spacecraft do not have angular velocity measurements, an estimator for the generalized velocity is derived and asymptotic stability is proven for the observer. The approach is tested on an experimental platform with a sphere shaped Autonomous Underwater Vehicle SATellite: AUVSAT, developed at the Norwegian University of Science and Technology.

    There was a good response to our questionnaire on the Bulletin (around 450 so far). Many thanks to all of you - your views are invaluable to us. Pending publication of the full figures, which will give latecomers time to take part in the survey, here we give here answers some of your most frequent comments. Thank you for the many warm tributes and messages of encouragement we received. We also received criticisms about the way information is handled in the Bulletin and on its circulation. In today's issue we reply to these two points. Why is the Bulletin politically correct ? Many respondents reproach the Bulletin for a lack of objectivity and for being too politically correct to the point of being a propaganda organ. It is true that the Bulletin is not a newspaper, but rather a bulletin of communication (like SLAC's Beam Line). What is the difference ? A newspaper is objectively independent of the subjects it reports on, and when its reporters write stories they dig around for information from all parties...

    Virtual slides are viewed using interactive software that enables the user to simulate the behaviour of a conventional optical microscope, like adjusting magnifications and navigating to any portion of the image. Nowadays, information about the performance and features of web-based solutions for reading slides in real environments is still scarce. The objective of this study is analyzing the subjective experience of pathologists with virtual slides, comparing the time needed to read slides using different web viewers and different network connections. Eight slides were randomly selected (4 biopsies and 2 cytologies) from Hospital General de Ciudad Real (HGCR) archives. Three different virtual slide web-viewing solutions were analyzed: Aperio web server, Olympus NetImage Server, and Aurora mScope. Five pathologists studied to time needed to access images of each virtual slide, selecting a panoramic view, 10 low magnification fields, and 20 high magnification fields. Aperio viewer is very efficient in overview images. Aurora viewer is especially efficient in lower magnifications (10x). For larger magnifications (20x and 40x) no significant differences were found between different vendors. Olympus was found to be the most user-friendly interface. When comparing Internet with intranet connections, despite being slower, users also felt comfortable using virtual slides through Internet connection. Available web solutions for virtual slides have different advantages, mainly in functionalities and optimization for different magnifications. Pathologists should select the solutions adapted to their needs.

  16. Shear wave reflection seismic surveying in the Trondheim harbour area - imaging of land slide processes

    Polom, U.; Hansen, L.; L'Heureux, S.; Longva, O.; Lecomte, I.; Krawczyk, C. M.

    2008-12-01

    The harbour area of Trondheim, Norway, was build on man-made land fillings at the coast of the Trondheim Fjord in several expansions since the last 80 years. The whole area is located on the deltaic sediments of the river Nidelven, which are overlying marine sediments that reach the bed rock in nearly 150 m depth. Some submarine land slides at the border of the sediment body nearby the harbour area were reported during the last decades. Therefore, many geological and geophysical investigations were carried out in recent years to explore the structure of the sediment body and its stability onshore and offshore in detail. Whereas high-resolution marine seismic methods archieved excellent results in the offshore area, common seismic investigations for the mostly paved harbour area itself were a difficult challenge. Therefore, SH polarized shear wave reflection seismics using a land streamer combined with a newly developed shear wave vibrator buggy of 30 kN peak force was applied, because this method is advantageous for paved surfaces. Overall 4.2 km 2.5D profiling was carried out in the harbour area along roads and parking places after optimizing of the field procedure. The whole operation was done at night in time slots from midnight to 5 am by road closures due to savety reasons and to minimize the noise from surrounding heavy traffic of trains, trucks and other heavy equipment. The field measurements achieved high resolution results of the sediment body structure, clear detection of the bedrock, and probably deeper structures within the bedrock. Due to the clear and continuous reflection events, also the shear wave velocity could be calculated at least down to the bedrock to indicate the stiffness of the sediment layers. The results of these onshore seismic profiles will be integrated in a combined onshore-offshore seismic profile grid for structural interpretation. Furthermore, the derived shear wave velocities will be combined with cone penetrometer testings and

    This report reviews mild gasification processes with respect to processing conditions and configurations. Special emphasis was placed on processes which could be commercialized within five years. Detailed market information was provided by J.E. Sinor concerning markets and economic considerations of the various processing steps. Processing areas studied include coal cleaning; mild gasification; and upgrading of the char, condensables, and hydrocarbon gases. Pros and cons in the different processing areas as well as ''gaps'' in pertinent data were identified and integrated into a detailed process development program. The report begins with a summary of the market assessment and an evaluation of the co-product. The impacts of feed materials and operating parameters--including coal rank, heating rate, pressure, agglomeration, temperature, and feed gas composition--on the co- products and processes were evaluated through a literature survey. Recommendations were made as to the preferred product specifications and operating parameters for a commercial plant. A literature review of mild gasification processes was conducted and evaluated with regard to product specification and operating parameters. Two candidate processes were chosen and discussed in detail with respect to scale-up feasibility. Recommendations were then made to process development needs to further consideration of the two processes. 129 refs., 33 figs., 16 tabs.

  10. Slide Activity along the eastern slope of the Gela Basin (offshore Sicily): First results from expedition MSM-15/3

    Huhn, K.; Strasser, M.; Freudenthal, T.; Foglini, F.; Trincardi, F.; Minisini, D.; Msm15/3 Working Group

    2010-12-01

    Submarine slides occur at all sediment bearing margins worldwide (Camerlenghi et al., 2009; Masson et al., 2006). Although numerous studies have dealt with mapping and monitoring of submarine landslide as well as investigations of trigger mechanisms and sediment failure processes, many open questions persist why a given slope fails whereas adjacent remains stable. Besides large slide events, smaller scaled mid-size slides became recently of particular importance because especially these local slides enable investigation of physical and kinematical processes during failure and to test a wide range of different trigger mechanisms. Hence, during the research expedition MSM15/3 we drilled two distinct landslides in the Gela Basin offshore south of Sicily (Italy) utilizing the MARUM sea floor drill rig (MeBo). These so-called ‘Twin Slides’ have previously been identified in water depth between 200 - 800m on the basis of side-scan sonar, Chirp seismics, swath bathymetry and shallow core data. Besides, these landslides are described as multiple failures likely controlled by specific stratigraphic surfaces acting as glide planes (Minisini et al., 2007; Minisini and Trincardi, 2009). Nevertheless, failure planes are located in depth inaccessible by conventional coring and we therefore lack groundtruthing of the geophysical data. Therefore, MeBo was deployed to drill e.g. critical subsurface intervals. A systematic MeBo drilling transect from the undisturbed slope apron to the depositional area of these landslide masses recovers up to 55 meter long cores, including the failure planes and stacked mass transport deposits in the proximal and distal areas, respectively. Sedimentological, geochemical, geophysical and geotechnical analysis of these core materials will enable (1) an age dating and estimation of the recurrence rate of mid-sized slide events and (2) a sediment physical characterization to gain a deeper insight into kinematics and physical processes during failure

    Submarine landslides are important geologic hazards. Although they have been the focus of research for decades, there is still a clear lack in knowledge with respect to the interplay between tectonic movements, slope architecture and sediment physical properties of slope strata, as well as gas hydrate dissociation as controlling factors of slope stability or respectively slope failure processes. The main scientific goal of the Sonne expedition SO247 undertaken in spring 2016 was to gain a better understanding of the factors controlling slope destabilization, especially the interaction of tectonic steepening and gas hydrate transformation, at different tectonic settings along the Hikurangi subduction zone east of New Zealand's North Island. This active continental margin is characterized by various potential triggers for slope failure, e.g. (I) a wide range of tectonic movements which are associated with high seismicity, numerous active faults, sediment uplift and slope over-steepening, and (II) large gas hydrate deposits whose current upper stability limit in some places correlates with the breakoff points of slides. The target areas of SO247 were the frontal accretionary ridge at Rock Garden and the Tuaheni landslide complex (TLC) further north offshore Gisborne. Bathymetric as well as high-resolution seismic reflection and Parasound data were used to select suitable position for 53 gravity cores with a total length of 150 m which were recovered along systematic transects from the undisturbed slope sections to the slid masses in both working areas. In addition, six long sediment cores (three in both working areas) with a total length of approx. 470 m were drilled utilizing the MARUM Bremen drill rig MeBo200. These include a 105 m long continuous sediment core (core recovery > 95%) from an undisturbed slope section in the vicinity of the Tuaheni slide complex. This core represented the first long (i.e. longer than 50 m) sediment record from the Hikurangi margin

The sliding mode technique finds its stronger justification in the utilization of a robust control law to model uncertainties. A sliding mode controller of the motor speed is then designed and simulated. Digital simulation results shows that the designed sliding speed controller realises a good dynamic behaviour of the motor, a perfect speed tracking with no overshoot and a good rejection of impact loads disturbance. The results of applying the sliding mode controller to a SRM give best performances and high robustness than those obtained by the application of a conventional controller (PI.

    Full Text Available These notes give a state of the art of numerical homogenization methods for linear elliptic equations. The guideline of these notes is analysis. Most of the numerical homogenization methods can be seen as (more or less different discretizations of the same family of continuous approximate problems, which H-converges to the homogenized problem. Likewise numerical correctors may also be interpreted as approximations of Tartar’s correctors. Hence the convergence analysis of these methods relies on the H-convergence theory. When one is interested in convergence rates, the story is different. In particular one first needs to make additional structure assumptions on the heterogeneities (say periodicity for instance. In that case, a crucial tool is the spectral interpretation of the corrector equation by Papanicolaou and Varadhan. Spectral analysis does not only allow to obtain convergence rates, but also to devise efficient new approximation methods. For both qualitative and quantitative properties, the development and the analysis of numerical homogenization methods rely on seminal concepts of the homogenization theory. These notes contain some new results. Ces notes de cours dressent un état de l’art des méthodes d’homogénéisation numérique pour les équations elliptiques linéaires. Le fil conducteur choisi est l’analyse. La plupart des méthodes d’homogénéisation numérique s’interprète comme des discrétisations (plus ou moins différentes d’une même famille de problèmes continus approchés qui H-converge vers le problème homogénéisé. De même, le concept de correcteur numérique s’interprète comme une approximation des correcteurs introduits par Tartar. Ainsi l’analyse de convergence repose essentiellement sur la théorie de la H-convergence.

    The U.S. Fish and Wildlife Service (Service) collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The survey was conducted to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. The survey results will inform Service performance planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plan (CCPs), Visitor Services, and Transportation Planning processes. The survey was conducted on 53 refuges across the National Wildlife Refuge System (Refuge System) to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. A total of 14,832 visitors agreed to participate in the survey between July 2010 and November 2011. In all, 10,233 visitors completed the survey for a 71% response rate. This report provides a summary of visitor and trip characteristics; visitor opinions about refuges and their offerings; and visitor opinions about alternative transportation and climate change, two Refuge System topics of interest. The Refuge System, established in 1903 and managed by the Service, is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 556 National Wildlife Refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts more than 45 million visitors annually, including 25 million people per year to observe and photograph wildlife, over 9 million to hunt and fish, and more than 10 million to participate in educational and interpretation programs. Understanding visitors and characterizing their experiences on national wildlife refuges are critical elements of managing these lands and meeting the goals of the Refuge System. These combined results are based on surveying at 53 participating

    Full Text Available We study the effects on results of participants completing a survey more than once, a phenomenon known as farming. Using data from a real social science study as a baseline, three strategies that participants might use to farm are studied by Monte Carlo simulation. Findings show that farming influences survey results and can cause both statistical hypotheses testing Type I (false positive and Type II (false negative errors in unpredictable ways.

    The survey provided by the College of American Pathologists (CAP) is chosen as one of the proficiency testing programs in Japan, and, recently, the numbers of participating facilities have increased. CAP provides 754 programs, and more than 1,000 tests were provided in 2014. Materials are translated as the "CAP global inter-laboratory comparison program" under the instruction of the Japanese Society of Laboratory Medicine (JSLM) selected from CAP surveys in Japan, and 68 programs and 261 items are provided. The total number of participating facilities was 174. CAP itself and the other services CAP provides are not well-known, while recognition of "the CAP survey as the proficiency test" has increased. The question "What is CAP and the CAP survey" was analyzed as a result of the questionnaire surveys conducted in 2014, and the advantage of the CAP survey and how to utilize it were considered. A questionnaire survey was conducted about the CAP survey for Japanese participants in 2014. Fifty-three questions were asked about their satisfaction level, intended use, and improvement. Eighty replies were analyzed. As a result, most CAP survey participants are satisfied. They intend to mainly use the CAP survey for their quality control. Furthermore, they can continuously monitor their systems throughout all testing phases as the survey has numbers of shipments a year and several specimens per each mailing. This helps in laboratory performance improvement. The Evaluation and Participant Summary (PSR) also effectively improves the laboratories' performance. CAP-accredited laboratories are required to participate in all survey programs concerning the test menu which they provide. Therefore, they have become accustomed to reviewing the evaluation and performing self-evaluation with a high usage rate of the Evaluation and PSR of the CAP survey. The questionnaire proved that performing the CAP survey properly enhanced the laboratories' quality control, and this meets the

    2014-01-01

    Full Text Available Background: Whole slide imaging (WSI offers a novel approach to digitize and review pathology slides, but the voluminous data generated by this technology demand new computational methods for image analysis. Materials and Methods: In this study, we report a method that recognizes stains in WSI data and uses kernel density estimator to calculate the stain density across the digitized pathology slides. The validation study was conducted using a rat model of acute cardiac allograft rejection and another rat model of heart ischemia/reperfusion injury. Immunohistochemistry (IHC was conducted to label ED1 + macrophages in the tissue sections and the stained slides were digitized by a whole slide scanner. The whole slide images were tessellated to enable parallel processing. Pixel-wise stain classification was conducted to classify the IHC stains from those of the background and the density distribution of the identified IHC stains was then calculated by the kernel density estimator. Results: The regression analysis showed a correlation coefficient of 0.8961 between the number of IHC stains counted by our stain recognition algorithm and that by the manual counting, suggesting that our stain recognition algorithm was in good agreement with the manual counting. The density distribution of the IHC stains showed a consistent pattern with those of the cellular magnetic resonance (MR images that detected macrophages labeled by ultrasmall superparamagnetic iron-oxide or micron-sized iron-oxide particles. Conclusions: Our method provides a new imaging modality to facilitate clinical diagnosis. It also provides a way to validate/correlate cellular MRI data used for tracking immune-cell infiltration in cardiac transplant rejection and cardiac ischemic injury.

    2017-09-01

    The Next Generation Transit Survey (NGTS) is a new wide-field, ground-based exoplanet survey designed to detect Neptunes and super-Earths transiting bright stars, which are amenable to precise radial velocity confirmation and mass determination. NGTS comprises an array of twelve independent robotised 20-cm telescopes located at ESO's Paranal Observatory in Chile, and has been operational since early 2016. While monitoring 10% of the southern sky during it's survey time, the facility achieves sub-mmag photometric precision, which is unprecedented for wide-field ground-based transit surveys. We will introduce NGTS, describe our novel planet detection and vetting pipeline, and present early science results: new confirmed and candidate exoplanets, low-mass eclipsing binaries, variable stars and stellar flares.

    By the time of this writing, the ongoing LAMOST Galactic surveys have collected approximately 4.5 million stellar spectra with signal-to-noise ratios better than 10 per pixel. This special issue is devoted to early results from the surveys, mostly based on the LAMOST Data Release 1 (DR1; Luo et al., this volume) that contains data secured by May 2013, the end of the first year of regular surveys, although a few studies have made use of data collected in the second year of regular surveys. LAMOST DR1 was released to the Chinese astronomical community and international partners in August 2013 and made public to the whole world in March 2015. Here we briefly review the scope and motivation, data reduction and release, as well as early results of the surveys. As the project advances, one can expect that these surveys will yield an exquisite description of the distribution, kinematics and chemistry of Galactic stellar populations, especially those within a few kpc of the Sun, a robust measurement of the local dark matter density, and, consequently, shed light on how our Galaxy, and other galaxies in general, form and evolve.

  12. Speak Up Speak Out Coalition Survey Results | Science ...

    Science.gov (United States)

    Comprehensive planning is a visionary planning process that integrates community values and land use policy. The Mayor of Duluth, Minnesota, directed the inclusion of two new values into the City’s comprehensive planning process to direct the community’s future, process: health and fairness. In order to understand the meanings of health and fairness that residents of the city hold, the Community Planning Department included questions in a city-wide survey of planning priorities. As a community organization reviewed the survey results that would inform the new directives, they realized that overburdened communities were underrepresented in the survey responses. To address this deficiency, the community organization asked the City of Duluth if they could conduct a survey of the underrepresented voices to ensure their input was included in the process. The Health in All Policies Coalition contacted the USEPA Office of Research and Development in Duluth, MN at the advice of the Planning Department. The support USEPA provided ensured that the Coalition could make recommendations to the City of Duluth based on systematically collected and analyzed data. This presentation will share the results of the survey. This presentation of the Speak Up Speak Out survey data represents support for local decision-making, technical assistance and data analysis. The data were collected and analyzed through advice and consultation with USEPA Office of Research and Development, an

  13. Do low survey response rates bias results? Evidence from Japan

    Directory of Open Access Journals (Sweden)

    Ronald R. Rindfuss

    2015-03-01

    Full Text Available Background: In developed countries, response rates have dropped to such low levels that many in the population field question whether the data can provide unbiased results. Objective: The paper uses three Japanese surveys conducted in the 2000s to ask whether low survey response rates bias results. A secondary objective is to bring results reported in the survey response literature to the attention of the demographic research community. Methods: Using a longitudinal survey as well as paradata from a cross-sectional survey, a variety of statistical techniques (chi square, analysis of variance (ANOVA, logistic regression, ordered probit or ordinary least squares regression (OLS, as appropriate are used to examine response-rate bias. Results: Evidence of response-rate bias is found for the univariate distributions of some demographic characteristics, behaviors, and attitudinal items. But when examining relationships between variables in a multivariate analysis, controlling for a variety of background variables, for most dependent variables we do not find evidence of bias from low response rates. Conclusions: Our results are consistent with results reported in the econometric and survey research literatures. Low response rates need not necessarily lead to biased results. Bias is more likely to be present when examining a simple univariate distribution than when examining the relationship between variables in a multivariate model. Comments: The results have two implications. First, demographers should not presume the presence or absence of low response-rate bias; rather they should test for it in the context of a specific substantive analysis. Second, demographers should lobby data gatherers to collect as much paradata as possible so that rigorous tests for low response-rate bias are possible.

  16. Diversity and Demographics of Zooarchaeologists: Results from a Digital Survey

    Directory of Open Access Journals (Sweden)

    Suzanne E. Pilaar Birch

    2015-12-01

    Full Text Available Nearly 25 years ago, a “Zooarchaeology Practitioner Survey” was distributed via conventional mail to individuals in the USA and Canada and received 122 responses over a period of several months in 1991. Now, a revised “Demographics in Zooarchaeology Survey” provides an update to  those data and assesses the current state of the field. The 2014 survey remained open for 3 months and received 288 responses from practitioners worldwide. Global participation was made possible by hosting the survey online. Key findings of the 1991 survey included disparities in employment rank for women despite similar levels of degree level attainment as men, a point which the 2014 survey sought to investigate. This trend appears to persist for those without the PhD and at the highest levels of income for those holding a PhD. In addition, the recent survey asked participants about their racial or ethnic identity in order to evaluate the demographic diversity of the discipline beyond sex, age, and nationality. Data regarding topical and geographic research area were also collected and reflect a subtle bias towards working with mammals and a focus on research questions grounded in prehistory in Europe and North America, followed by Australia and Southwest Asia. Results are compared with those of the earlier survey and membership information from the International Council for Archaeozoology.

    We present the Multifrequency Snapshot Sky Survey (MSSS), the first northern-sky Low Frequency Array (LOFAR) imaging survey. In this introductory paper, we first describe in detail the motivation and design of the survey. Compared to previous radio surveys, MSSS is exceptional due to its intrinsic multifrequency nature providing information about the spectral properties of the detected sources over more than two octaves (from 30 to 160 MHz). The broadband frequency coverage, together with the fast survey speed generated by LOFAR's multibeaming capabilities, make MSSS the first survey of the sort anticipated to be carried out with the forthcoming Square Kilometre Array (SKA). Two of the sixteen frequency bands included in the survey were chosen to exactly overlap the frequency coverage of large-area Very Large Array (VLA) and Giant Metrewave Radio Telescope (GMRT) surveys at 74 MHz and 151 MHz respectively. The survey performance is illustrated within the MSSS Verification Field (MVF), a region of 100 square degrees centered at (α,δ)J2000 = (15h,69°). The MSSS results from the MVF are compared with previous radio survey catalogs. We assess the flux and astrometric uncertainties in the catalog, as well as the completeness and reliability considering our source finding strategy. We determine the 90% completeness levels within the MVF to be 100 mJy at 135 MHz with 108″ resolution, and 550 mJy at 50 MHz with 166″ resolution. Images and catalogs for the full survey, expected to contain 150 000-200 000 sources, will be released to a public web server. We outline the plans for the ongoing production of the final survey products, and the ultimate public release of images and source catalogs.

    The National Wildlife Refuge System (Refuge System), established in 1903 and managed by the U.S. Fish and Wildlife Service (Service), is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 560 national wildlife refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts nearly 45 million visitors annually, including 34.8 million people who observe and photograph wildlife, 9.6 million who hunt and fish, and nearly 675,000 teachers and students who use refuges as outdoor classrooms. Understanding visitor perceptions of refuges and characterizing their experiences on refuges are critical elements of managing these lands and meeting the goals of the Refuge System. The Service collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The purpose of the survey was to better understand visitor experiences and trip characteristics, to gauge visitors’ levels of satisfaction with existing recreational opportunities, and to garner feedback to inform the design of programs and facilities. The survey results will inform performance, planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plans (CCPs), visitor services, and transportation planning processes. This Data Series consists of 25 separate data files. Each file describes the results of the survey for an individual refuge and contains the following information: • Introduction: An overview of the Refuge System and the goals of the national surveying effort. • Methods: The procedures for the national surveying effort, including selecting refuges, developing the survey instrument, contacting visitors, and guidance for interpreting the results.• Refuge Description: A brief description of the refuge location, acreage, purpose, recreational

    As the largest, clearly defined building blocks of our universe, galaxy clusters are interesting astrophysical laboratories and important probes for cosmology. X-ray surveys for galaxy clusters provide one of the best ways to characterize the population of galaxy clusters. We provide a description of the construction of the NORAS II galaxy cluster survey based on X-ray data from the northern part of the ROSAT All-Sky Survey. NORAS II extends the NORAS survey down to a flux limit of 1.8 × 10{sup −12} erg s{sup −1} cm{sup −2} (0.1–2.4 keV), increasing the sample size by about a factor of two. The NORAS II cluster survey now reaches the same quality and depth as its counterpart, the southern REFLEX II survey, allowing us to combine the two complementary surveys. The paper provides information on the determination of the cluster X-ray parameters, the identification process of the X-ray sources, the statistics of the survey, and the construction of the survey selection function, which we provide in numerical format. Currently NORAS II contains 860 clusters with a median redshift of z  = 0.102. We provide a number of statistical functions, including the log N –log S and the X-ray luminosity function and compare these to the results from the complementary REFLEX II survey. Using the NORAS II sample to constrain the cosmological parameters, σ {sub 8} and Ω{sub m}, yields results perfectly consistent with those of REFLEX II. Overall, the results show that the two hemisphere samples, NORAS II and REFLEX II, can be combined without problems into an all-sky sample, just excluding the zone of avoidance.

    Despite President Obama's well-publicized excursion to Kotzebue in 2015 - the first presidential visit to the US Arctic - most of the public remains unaware that their country has any inhabited Arctic territory. This striking result emerged from two nationwide surveys in 2016 that assessed public knowledge and perceptions about the changing polar regions. Other questions tested knowledge about polar geography and conditions, sought perceptions on the importance of global impacts such as sea level or extreme weather, and asked for opinions about trusted information sources (scientists, TV news, websites, etc.) and preferred mitigation policies. With an oversampling of Alaska residents, the POLES survey allows comparisons between perceptions of Alaska residents (including rural Alaska) and people from the other 49 states. It also supports analysis of relationships among knowledge, opinions, information sources, and individual respondent characteristics. We take a first look at results, analysis and interpretation of this unique new polar-oriented survey. Image: "Which country has territory with thousands of people living north of the Arctic Circle? US, China, Estonia, Britain, or none of these?" Graph shows results from a July 2016 pretest with 523 interviews; full results from two nationwide surveys, including Alaska/49-state comparisons, will be presented at AGU.

    We present the selection algorithm and anticipated results for the Time Domain Spectroscopic Survey (TDSS). TDSS is an Sloan Digital Sky Survey (SDSS)-IV Extended Baryon Oscillation Spectroscopic Survey (eBOSS) subproject that will provide initial identification spectra of approximately 220,000 luminosity-variable objects (variable stars and active galactic nuclei across 7500 deg{sup 2} selected from a combination of SDSS and multi-epoch Pan-STARRS1 photometry. TDSS will be the largest spectroscopic survey to explicitly target variable objects, avoiding pre-selection on the basis of colors or detailed modeling of specific variability characteristics. Kernel Density Estimate analysis of our target population performed on SDSS Stripe 82 data suggests our target sample will be 95% pure (meaning 95% of objects we select have genuine luminosity variability of a few magnitudes or more). Our final spectroscopic sample will contain roughly 135,000 quasars and 85,000 stellar variables, approximately 4000 of which will be RR Lyrae stars which may be used as outer Milky Way probes. The variability-selected quasar population has a smoother redshift distribution than a color-selected sample, and variability measurements similar to those we develop here may be used to make more uniform quasar samples in large surveys. The stellar variable targets are distributed fairly uniformly across color space, indicating that TDSS will obtain spectra for a wide variety of stellar variables including pulsating variables, stars with significant chromospheric activity, cataclysmic variables, and eclipsing binaries. TDSS will serve as a pathfinder mission to identify and characterize the multitude of variable objects that will be detected photometrically in even larger variability surveys such as Large Synoptic Survey Telescope.

    A survey based on a statistically representative sample of 5000 dwellings distributed in 200 administrative districts has been planned in Italy to evaluate exposure indoors. Knowledge of the distribution of radon concentration and gamma absorbed doses in air allows a determination of the average risk to which the population is subjected and of the number of dwellings exceeding a given action level. Radon concentration is monitored for two 6 month periods, while the [gamma] exposure is measured for only one semester. Duplicate radon measurements are performed by using etched track detectors (typically LR-115 II type and CR-39). The survey is carried out at district level by local laboratories, under the coordination of the two central institutions ENEA/DISP and ISS. The overall structure of the survey is described together with the first results obtained. (author).

    The growing use of social media is transforming the way health care professionals (HCPs) are communicating. In this changing environment, it could be useful to outline the usage of social media by radiologists in all its facets and on an international level. The main objective of the RANSOM survey was to investigate how radiologists are using social media and what is their attitude towards them. The second goal was to discern differences in tendencies among American and European radiologists. An international survey was launched on SurveyMonkey ( https://www.surveymonkey.com ) asking questions about the platforms they prefer, about the advantages, disadvantages, and risks, and about the main incentives and barriers to use social media. A total of 477 radiologists participated in the survey, of which 277 from Europe and 127 from North America. The results show that 85 % of all survey participants are using social media, mostly for a mixture of private and professional reasons. Facebook is the most popular platform for general purposes, whereas LinkedIn and Twitter are more popular for professional usage. The most important reason for not using social media is an unwillingness to mix private and professional matters. Eighty-two percent of all participants are aware of the educational opportunities offered by social media. The survey results underline the need to increase radiologists' skills in using social media efficiently and safely. There is also a need to create clear guidelines regarding the online and social media presence of radiologists to maximize the potential benefits of engaging with social media.

  12. Protein sliding and hopping kinetics on DNA

    DeSantis, Michael C; Wang, Y M

    2010-01-01

    Using Monte-Carlo simulations, we deconvolved the sliding and hopping kinetics of GFP-LacI proteins on elongated DNA from their experimentally observed seconds-long diffusion trajectories. Our simulations suggest the following results: (1) in each diffusion trajectory, a protein makes on average hundreds of alternating slides and hops with a mean sliding time of several tens of ms; (2) sliding dominates the root mean square displacement of fast diffusion trajectories, whereas hopping dominates slow ones; (3) flow and variations in salt concentration have limited effects on hopping kinetics, while in vivo DNA configuration is not expected to influence sliding kinetics; furthermore, (4) the rate of occurrence for hops longer than 200 nm agrees with experimental data for EcoRV proteins.

    1992-01-01

    Preliminary results from a deep (70 ksec) Rosat survey of the high galactic latitude selected area Lynx.3A are presented. Lynx.3A sensitivity was previously studied in both the optical radio, with deep Westerbork surveys and deep multicolor Charge Couple Device (CCD) images form the Palomar 200 inch Four-Shooter. About 70 x-ray sources were detected within the central 40 foot diameter region of the Position Sensitive Proportional Counter (PSPC), observed surface densities of approximately 200 x-ray sources/sq deg are suggested, and these x-ray sources alone account for approximately 30 percent of the cosmic x-ray background (0.9 to 2.2 keV). An initial look at the observed x-ray logN - logS curve is presented, but a detailed assessment requires further study. The 4 sigma limit of about 7 times 10 to the minus 15th power erg/s.sq cm (0.5 to 2.0 keV) is considerably deeper then the Einstein deep surveys, and of comparable sensitivity to the deepest current Rosat surveys. Cross correlation with our Four Shooter optical catalogs yields at least one likely optical candidate for nearly all of the Rosat x-ray sources; a number of the likely optical identifications have colors of quasi-stellar objects (and stellar PSF), but in other cases galaxies/groups are also viable candidates.

    The sliding mode control methodology has proven effective in dealing with complex dynamical systems affected by disturbances, uncertainties and unmodeled dynamics. Robust control technology based on this methodology has been applied to many real-world problems, especially in the areas of aerospace control, electric power systems, electromechanical systems, and robotics. Sliding Mode Control and Observation represents the first textbook that starts with classical sliding mode control techniques and progresses toward newly developed higher-order sliding mode control and observation algorithms and their applications. The present volume addresses a range of sliding mode control issues, including: *Conventional sliding mode controller and observer design *Second-order sliding mode controllers and differentiators *Frequency domain analysis of conventional and second-order sliding mode controllers *Higher-order sliding mode controllers and differentiators *Higher-order sliding mode observers *Sliding mode disturbanc...

    2008-10-01

    Most staphylococci grown from blood cultures are contaminants. Since they are microscopically indistinguishable from non-contaminants, considerable time and resources may be spent following up all patients with positive blood cultures before the identification is made the following day. Since there is no formal guidance or standard available in this area, this report surveyed practice in our region. An interview was conducted by telephone, using a standardised questionnaire. Results were analysed using descriptive techniques. The majority of microbiologists did not communicate all presumptive staphylococci but waited for identification in some cases. There is a range of practice in laboratories due to conflicting pressures: limited time, fear of criticism if results are not phoned, fear of causing confusion with provisional information and lack of clarity concerning what is "good practice." This survey concludes that a decision not to telephone every presumptive Staphylococcus in blood cultures on Day 1 is reasonable.

    New high-resolution bathymetric and seismic-reflection surveys have imaged large (7) individual overlapping slides along the western margin of Santa Cruz Basin (SCB slide); 2) a series of slumps and slide scars on the slope south of San Pedro shelf (SPS slide); and 3) a slope failure along the shelf edge in northern San Diego County, termed the Del Mar slide. The SCB slide complex extends for 30 km along the western slope of Santa Cruz Basin, with debris lobes extending 5-8 km into the basin. Head scarps of some of these slides are 50-75 m high. The SPS slide complex also appears to consist of multiple slides, which roughly parallel the Palos Verdes Fault and the San Gabriel Canyon submarine channel on the shelf edge and slope south of San Pedro shelf. Slide deposits associated with this complex are only partially mapped due to limited high-resolution bathymetric coverage, but extend to the south in the area SW of Lasuen Knoll. Seismic-reflection profiles show that some of these deposits are up to 20 m thick. The Del Mar slide is located about 10 km north of La Jolla Canyon and extends about 6 km along the shelf edge. The head scarp lies along the trend of a branch of the Rose Canyon Fault Zone. Radiocarbon ages of sediment overlying this slide indicate the Del Mar slide is approximately 12-16 ka. These large slide complexes have several characteristics in common. Nearly all occur in areas of tectonic uplift. All of the complexes show evidence of recurrent slide activity, exhibiting multiple headwall scarps and debris lobes, and where available, high-resolution seismic-reflection profiles of these slide areas provide evidence of older, buried mass transport deposits. Assuming typical sedimentation rates, the recurrence interval of major slide events appears to be on the order of tens of thousands of years. Most of the slide complexes do not appear to be located in areas of high sediment input. The SCB and Del Mar slides are in areas receiving relatively small

    Fertility preservation (FP) is a widespread practice in paediatric oncology when gonadotoxic medications such as cyclophosphamide (CPO) are used. FP practice outside of oncology has not been studied, although nephrologists regularly use CPO. This is the first study to explore FP practice by paediatric nephrologists when CPO is used. Survey study. Descriptive statistics and chi-squared analyses were employed to analyse the data. US paediatric nephrologists were sent a survey via email. The survey queried participants about FP practice behaviours, FP attitudes and barriers to practice. Of 579 nephrologists invited, 32% responded to the survey. CPO was dosed in mg/kg by 23% of physicians, g/m(2) by 40% and both by 37%. About 80% agreed that pubertal females should be offered a fertility referral, while 58% report that they actually refer. Factors negatively associated with referral include lack of training, lack of referral network and adherence to gonadotoxic dose limits. Results were similar for male patients. The survey showed that FP practice in the United States is widespread among nephrologists. Lack of referral networks is a notable barrier for nephrologists. Perceived adherence to dose limits may be problematic given the variable dosing regimens utilised. This is due to the risk of unintended overdose in large adolescents dosed in mg/kg whose cumulative dose exceeds gonadotoxic limits in g/m(2) . This paper has implications for nephrology care providers and other specialists who utilise CPO, generalists who care for these patients and oncologists with extant FP referral networks. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Full Text Available Truly fuelwood is the principal source indeed even exclusive of energy in all developing countries. Some studies have been made in some towns of these countries in order to know energy consumption. In other countries on the other hand, these studies fail. Statistics that are available in those on fuelwood are the approximated values, often dissimilar and summary curried up with the politic object by the authorities. This is the case of Kinshasa, county town of Zaire. To cover up the deficiency inquiries on real norms of the consumption of fuelwood, we have held a sample survey in households of Kinshasa. Other complementary information that may implicate on the consumption fuelwood have been realized too close to other users of fuelwood. The results of the sample survey make up the backdrop of our work.

    Data have been lacking to answer many questions raised in the clinical literature and by the US Food and Drug Administration with regard to patient satisfaction with breast implants, informed consent, the impact of augmentation on quality of life, repeat operations, and other issues related to breast augmentation. The authors conducted an online survey of women with and without breast implants to collect data on key issues related to breast augmentation. A survey including 177 questions was posted on the Web site www.implantinfo.com for 6 months, from August 2001 to February 2002. The survey was aimed at women who had undergone augmentation and those who were considering augmentation but had not yet undergone surgery. The raw data were analyzed by Data Harbor (Chicago, IL), an independent data management and technology development company with experience in managing large, complex medical databases. The survey was completed by 4011 women, including 2273 who had received breast implants and 1738 who were considering augmentation. Among the key findings: More than half of the women who had undergone breast augmentation and those who were considering the procedure thought about the decision for at least 3 years before proceeding. Most women who underwent breast augmentation (88%) were satisfied with the results, and 93% said they would recommend the procedure to friends or family members. Nearly all women who received implants thought the surgery improved their overall appearance (92%) and self-confidence (82%) but said it did not result in significant changes in their marriage/dating activities, careers, or social lives. At least 92% said their surgeons had answered their questions and listened to their concerns, and more than 75% said they remembered being informed of the risks of surgery. The percentage of women with breast pain was greater among women with implants than among those without. However, other physical symptoms, such as those associated with

    A survey conducted in 2008 among 346 American middle school students in several cities determined that 82.7% of respondents found bullying to be a problem of some degree, with 46.0% rating it a "medium", "bad", or "very bad" problem. It was found that 89% had witnessed an act of bullying and 49.1% said they had been the victim of a bully. Boys were significantly more likely than girls to say that a victim deserved to be bullied (11.1% vs. 1.3%, p = 0.01), whereas girls were significantly more likely than boys to fail to intervene because they did not know what to do (30.3% for girls vs. 11.1%, p bullied another (46.2% boys, 41.1% girls, p = 0.34); however, girls were significantly more likely than boys to bully by excluding others and gossiping about them than by hitting, teasing, or threatening. Cyberbullying, surveyed as a distinct entity, had affected 31.1% of respondents directly, with similar results from 2006 to 2007 surveys. Of those who found conventional bullying a "bad" or "very bad" problem at their schools, numbers fell from 17.3% in 2006-2007 vs. 11.3% in 2008.

    The NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) began in 1999 with the commissioning of NIRSPEC on Keck II. In the first phase of the survey, J-band spectra of 53 objects covering all spectral types from M6 to T8 were obtained at a resolving power of R 2000 (McLean et al. 2003). This poster presents results from the second phase of the survey, which focused on high-resolution (R 20,000) J-band observations for a sample of 16 very low mass stars and brown dwarfs from M2.5 to T6 (McLean et al. 2006, submitted). By comparing opacity plots and line lists to the high-resolution spectra we identify hundreds of FeH, H2O, and atomic features and analyze how these features change with spectral type. We also begin to explore the apparently complex dependence of spectral features on the metallicity and surface gravity of brown dwarf atmospheres, which is the topic of the current phase of the BDSS. Data presented herein were obtained at the W.M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W.M. Keck Foundation.

    This Month in Astronomical History is a short (~500 word) column on the AAS website that revisits significant astronomical events or the lives of people who have made a large impact on the field. The monthly column began in July 2016 at the request of the Historical Astronomical Division. Examples of topics that have been covered include Comet Shoemaker-Levy’s collision with Jupiter, the discovery of the moons of Mars, the life of Edwin Hubble, Maria Mitchell’s comet discovery, and the launch of Sputnik II. A survey concerning the column is in progress to ensure the column addresses the interests and needs of a broad readership, including historians, educators, research astronomers, and the general public. Eleven questions focus on the style and content of the column, while eight collect simple demographics. The survey has been available on the AAS website since and was mentioned in several AAS newsletters; however, non-members of AAS were also recruited to include respondents from a variety of backgrounds. Preliminary results of the survey are presented and will be used to hone the style and content of the column to serve the widest possible audience.

    Geoelectric methods are sensitive to material properties which can be used to investigate subsurficial processes at contaminated sites. Electrical resistivity tomography (ERT) measures the electrical resistivity distribution in the ground; the self-potential (SP) method is based on source current densities resulting from ground water flow; and induced polarization (IP) responds to geochemical interactions between mineral surfaces and pore fluids. Ground water flow patterns and contaminant migration may be better understood if the results of these survey methods are interpreted jointly rather than separately. The purpose of this project is to jointly interpret results of geophysical surveying and laboratory characterization of soil and ground water samples to assess ground water flow patterns and contaminant migration at a site within the Oak Ridge National Laboratory. Historical disposal of liquid waste containing nitric acid and uranium in unlined ponds has resulted in contamination of soil and ground water. ERT, SP, and IP surveying was performed downgradient of the source area and the geophysical behavior of sediment and ground water samples was investigated in the laboratory. Measured electrical conductivity and self-potential anomalies coincided with elevated nitrate and uranium concentrations indicating preferential flow from the source area. The self-potential response can be related to ground water flow either by calculating the excess of charge in the diffuse layer surrounding mineral surfaces or by the streaming potential coupling coefficient. Geochemical reactions between pore water and minerals and their surfaces were modeled using the contaminant transport software TOUGHREACT. Surface complexation modeling using the Gouy-Chapman diffuse double layer was used to simulate charge density-surface potential relationship. Laboratory measurements of the streaming potential coupling coefficient of sediment samples at various pH and salt concentrations were

    Full Text Available Introduction: The therapeutic benefits of yoga and meditation are well documented, yet little is known about the practice of yoga in Australia or elsewhere, whether as a physical activity, a form of therapy, a spiritual path or a lifestyle. Materials and Methods: To investigate the practice of yoga in Australia, a national survey of yoga practitioners was conducted utilizing a comprehensive web-based questionnaire. Respondents were self-selecting to participate. A total of 3,892 respondents completed the survey. Sixty overseas respondents and 1265 yoga teachers (to be reported separately were excluded, leaving 2,567 yoga practitioner respondents. Results: The typical yoga survey respondent was a 41-year-old, tertiary educated, employed, health-conscious female (85% women. Asana (postures and vinyasa (sequences of postures represented 61% of the time spent practicing, with the other 39% devoted to the gentler practices of relaxation, pranayama (breathing techniques, meditation and instruction. Respondents commonly started practicing yoga for health and fitness but often continued practicing for stress management. One in five respondents practiced yoga for a specific health or medical reason which was seen to be improved by yoga practice. Of these, more people used yoga for stress management and anxiety than back, neck or shoulder problems, suggesting that mental health may be the primary health-related motivation for practicing yoga. Healthy lifestyle choices were seen to be more prevalent in respondents with more years of practice. Yoga-related injuries occurring under supervision in the previous 12 months were low at 2.4% of respondents. Conclusions: Yoga practice was seen to assist in the management of specific health issues and medical conditions. Regular yoga practice may also exert a healthy lifestyle effect including vegetarianism, non-smoking, reduced alcohol consumption, increased exercise and reduced stress with resulting cost benefits

    Objective: Our paper presents findings from the first population survey of stigma in Canada using a new measure of stigma. Empirical objectives are to provide a descriptive profile of Canadian’s expectations that people will devalue and discriminate against someone with depression, and to explore the relation between experiences of being stigmatized in the year prior to the survey among people having been treated for a mental illness with a selected number of sociodemographic and mental health–related variables. Method: Data were collected by Statistics Canada using a rapid response format on a representative sample of Canadians (n = 10 389) during May and June of 2010. Public expectations of stigma and personal experiences of stigma in the subgroup receiving treatment for a mental illness were measured. Results: Over one-half of the sample endorsed 1 or more of the devaluation discrimination items, indicating that they believed Canadians would stigmatize someone with depression. The item most frequently endorsed concerned employers not considering an application from someone who has had depression. Over one-third of people who had received treatment in the year prior to the survey reported discrimination in 1 or more life domains. Experiences of discrimination were strongly associated with perceptions that Canadians would devalue someone with depression, younger age (12 to 15 years), and self-reported poor general mental health. Conclusions: The Mental Health Experiences Module reflects an important partnership between 2 national organizations that will help Canada fulfill its monitoring obligations under the United Nations Convention on the Rights of Persons with Disabilities and provide a legacy to researchers and policy-makers who are interested in monitoring changes in stigma over time.

    This study's objective was to assess the patient safety culture in a large, integrated health delivery system's pharmacy department to allow for benchmarking with other health systems. This was a cross-sectional survey conducted in a pharmacy department consisting of staff members who provide dispensing, clinical, and support services within an integrated health delivery system. The U.S. Agency for Healthcare Research and Quality's 11-composite, validated Pharmacy Survey on Patient Safety Culture questionnaire was transcribed into an online format. All departmental staff members were invited to participate in this anonymous survey. Cronbach α and overall results and contrasts between dispensing and clinical services staff and dispensing pharmacists and technicians/clerks as percentage positive scores (PPSs) are presented. Differences in contrasts were assessed with χ tests of association. Completed questionnaires were received from 598 (69.9%) of 855 employees. Cronbach α ranged from 0.55 to 0.90. Overall, the highest and lowest composite PPSs were for patient counseling (94.5%) and staffing and work pressure (44.7%), respectively. Compared with dispensing service, the clinical service participants had statistically higher PPSs for all composites except patient counseling, communication about mistakes, and staffing and work pressure (all P > 0.05). The technicians/clerks had a statistically higher PPS compared with the pharmacists for communication about mistakes (P = 0.007). All other composites were equivalent between groups. Patient counseling consistently had the highest PPS among composites measured, but opportunities existed for improvement in all aspects measured. Future research should identify and assess interventions targeted to improving the patient safety culture in pharmacy.

    Full Text Available The paper presents some results of the 2006 Sava survey. The investigation was carried out at four locations along 188 km of the Serbian stretch of the Sava River (206 km of the river belongs to Serbia. Among other things (physical and chemical properties of water and sediment, phytoplankton, and phytobenthos, the study included investigation of aquatic macroinvertebrates. Sixty-two taxa were identified in this typical lowland river. Mollusks and oligochaetes were the most diverse groups of macroinvertebrates. Our results support the hypothesis that the Sava River is an important bio-invasion trajectory, a part of the Southern Invasive Corridor of Europe. Five alien macroinvertebrate taxa were identified, some of which (Corbicula fluminea, Branchyura sowerbyi, and Anodonta woodiana were found to be important components of the community.

    Exoplanet phase curves provide a wealth of information about exoplanet atmospheres, including longitudinal constraints on atmospheric composition, thermal structure, and energy transport, that continue to open new doors of scientific inquiry and propel future investigations. The measured heat redistribution efficiency (or ability to transport energy from a planet's highly-irradiated dayside to its eternally-dark nightside) shows considerable variation between exoplanets. Theoretical models predict a correlation between heat redistribution efficiency and planet temperature; however, the latest results are inconsistent with current predictions. We will present first results from a 660-hour Spitzer phase curve survey program that is targeting six short-period extrasolar planets. We will compare the measured heat redistribution efficiencies with planet temperature and rotation rate, examine trends in the phase curve peak offset, and discuss cloud coverage constraints. We will conclude with how to move forward with phase curve observations in the era of JWST.

    Background The aim of this study was to determine whether toe sliding is more likely to cause knee injuries than flatfoot sliding in curling. Methods Twelve curlers participated in the study, each delivering 12 stones. Six stones per volunteer were delivered using a flatfoot slide and six were delivered using a toe slide. The Pedar-X in-shoe pressure system recorded the plantar pressure during each of the slides, while a sagittal plane digital video recorded the body position of the curler. Measurements were taken from the video recordings using a software overlay program (MB Ruler), and this, combined with the Pedar-X data, gave the overall joint force in the tuck knee. Results The knee joint force for toe sliding was more than double that of flatfoot sliding (p<0.05). There was a strong correlation between the increase in knee joint force and the increase in the moment arm of the ground reaction force. Images produced using the three-dimensional Vicon system confirm that toe sliding produces a larger moment arm than flatfoot sliding. Conclusion Injuries are more likely to occur in toe sliding, compared with flatfoot sliding, due to the increase in force and moment, pushing the weight of the curler forward over the knee, which could make the adopted position less stable. Curlers might consider avoiding toe sliding to reduce the risk of knee injuries if the two types of delivery could be performed equally well. PMID:29021906

  6. A Bathymetric Survey of Lake Toba, Indonesia: Further Results

    Lake Toba, the largest caldera lake in the world, formed following a supervolcano eruption 74,000 years ago in northern Sumatra. Explosive eruption of ~2800 km3 of silicic magma from a batholith sized magma body produced a 100 x 30 x 2 km deep caldera. Approximately 2/3 of the caldera floor is now covered by Lake Toba, obscuring volcanic landforms and geologic features critical to understanding the history of the caldera. In September 2005, we initiated a bathymetric survey of Lake Toba using a GPS linked sonar device mounted to a small boat. Traveling at a speed of 3-10 km/h, and using a bottom depth sampling rate of 1 sounding/sec, sonar data was collected along almost 200 km of transect lines. This survey produced lake-bottom profiles with detailed bathymetric expression, indicating that it would be possible to generate a high resolution bathymetric map of Lake Toba with additional surveying. The second phase of our data collection was done in May 2008. Collectively, the survey now consists of about 90 separate transect lines over nearly 600 km of lake bottom. Results from both surveys allow several first order observations concerning caldera formation, resurgent doming, lava dome emplacement, and large scale erosional events as follows. Samosir Island is a partly submerged resurgent dome whose overall size (~60 x 20 km) and shape can now be accurately determined. The dome retains its asymmetrical shape below the water line with gentle westward slopes that merge into the caldera wall. Its steep east face rapidly descends to water depths of >400 m near the eastern caldera margin. The Uluan block appears to be a smaller, symmetrical equivalent of the Samosir dome. However, its extremely steep western face is more similar to the abrupt caldera collapse scar than the east face of Samosir. The deepest parts of the lake are found at the base of the ring fracture fault, approximately 0.5 km from the shoreline, with depths of 500 m recorded along the northeastern ring

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

    Full Text Available Purpose: identify by means of a survey the off-label treatments more often used in the oncohaematology area, as well as to know the established procedures and criteria used to authorise those treatments. Methods: a four-section survey was designed: 1 demographic data and hospital activity, 2 Off-label treatments protocol, 3 Approval criteria and 4 Off-label oncology treatments conducted during the last year. Results: in 42.1% of the hospitals it’s needed an authorisation before dispensing in more tan 80% of the treatments. The most influential factor in the approval-dispensation system is the available evidence. The consent of the hospital management with previous Pharmacy department’s report was the most common authorisation procedure. 55.3% of the hospitals settled specific patient criteria to help the decision-making altogether with the available safety and efficacy data of the drug for the requested indication. In most centers a lower level of evidence is accepted if there are no therapeutic alternatives as well as in tumors of low prevalence. Most of the centers have not clearly established a criterion of effectiveness to consider a benefit as clinically relevant, nor the cost-effectiveness threshold for approving a FFT. Conclusions: there is a great variability in the off-label treatments use and also in the criteria used for its approval.

    Salvia divinorum is a hallucinogenic plant with ethnopharmacological and recreational uses. It differs from classic serotonergic hallucinogens such as LSD and psilocin in both phenomenology and potent agonist activity of the active component salvinorin A at κ-opioid receptors. Awareness of S. divinorum has grown recently, with both an increase in its public representation and concern over its potential harmful effects. This discussion is particularly relevant as S. divinorum is legal to use in many countries and regions and easily available through online retailers. Drawing upon previous investigations of S. divinorum and other hallucinogens, this study surveyed 154 recent users and questioned them on their use behaviours, consequences of use and other attitudinal measures. Although reporting an extensive substance use history, and considering the limitations of online surveys, there was little evidence of dysfunctional S. divinorum use, and few reports of troubling adverse consequences of use. Furthermore, there was no evidence that users exhibited increased schizotypy. Respondents reported that S. divinorum produced mixed hallucinogenic and dissociative effects, which lends support to assertions that it phenomenologically differs from other hallucinogens with primary serotonergic activity. The functions of use changed with greater experiences with the drug, and although many respondents reported use of S. divinorum as an alternative to illegal drugs it, was apparent that legal proscription would be unlikely to dissuade them from use. These results are discussed with reference to psychopharmacologically informed public health responses to substance use.

    STARtorialist (startorialist.com) is a Tumblr-based blog that curates the proliferation of "Astro Fashion" - clothing accessories, decor, and more - with the goal of celebrating the beauty of the universe and highlighting the science behind the astronomical imagery. Since launching in January 2013, we have written over 1000 unique posts about everything from handmade and boutique products to mass-produced commercial items to haute couture seen on fashion runways. Each blog post features images and descriptions of the products with links to the original astronomical images or other relevant science content. We also feature profiles of astronomers, scientists, students, and communicators wearing, making, or decorating with "startorial" items. Our most popular posts accumulate hundreds or thousands of notes (faves or reblogs, in Tumblr parlance), and one post has nearly 150,000 notes. In our second year, we have grown from 1,000 to just shy of 20,000 followers on Tumblr, with an increased audience on Twitter, Instagram, and Facebook as well. We present preliminary results from a reader survey conducted September-October 2015 in collaboration with science communication researcher Dr. Paige Jarreau. The survey provides data on reader habits, motivations, attitudes, and demographics in order to assess how STARtorialist has influenced our readers' views on science, scientists, and the scientific community as a whole.

    The Danish Emergency Management Agency (DEMA) in co-operation with the Technical University of Denmark (TUD), Department of Automation, participated in the international exercise RESUME-95 arranged in Finland in August 1995. DEMA performed measurement with their airborne gamma-ray surveying system. Surveys were done in the three areas known as AREA I, II, III. Results from AREA II (3 km x 6 km) show that the apparent {sup 137}Cs deposition assuming a deposition profile equal to the profile in AREA I based on soil samples varies from a few 10th kBqm{sup -2} up to 110 kBqm{sup -2}. However, a detailed analysis using a new method, Noise Adjusted Singular Value Decomposition (NASVD), shows that the true variations probably are smaller and that the observed differences to some extend are due to major variations in the depth distribution of the cesium. For example agricultural areas appears to have cesium much deeper deposit than the undisturbed areas. Another interesting result is that the NASVD analysis shows that the ration of {sup 134}Cs to {sup 137}Cs is fixed and approximately 0.03 (August 1995) a number in good agreement with the expected ratio from the Chernobyl accident. No true real-time software for source detection is yet integrated in the Danish system. Results from AREA III, however, show that the implemented software for rapid post processing of data worked excellent for detection of radioactive sources. Post analysis using NASVD demonstrates that all sources except for a small {sup 137}Cs source can be localized. (au).

    The Canadian Health Measures Survey (CHMS) pre-test was conducted to provide information about the challenges and costs associated with administering a physical health measures survey in Canada. To achieve the specific objectives of the pre-test, protocols were developed and tested, and methods for household interviewing and clinic testing were designed and revised. The cost, logistics and suitability of using fixed sites for the CHMS were assessed. Although data collection, transfer and storage procedures are complex, the pre-test experience confirmed Statistics Canada's ability to conduct a direct health measures survey and the willingness of Canadians to participate in such a health survey. Many operational and logistical procedures worked well and, with minor modifications, are being employed in the main survey. Fixed sites were problematic, and survey costs were higher than expected.

    We present here the latest results obtained from the American French collaboration called the Dark energy American French Team/French American DArk energy Team (DAFT/FADA). The goal of the DAFT/FADA collaboration is to carry out a weak lensing tomography survey of z = 0.4-0.9 rich clusters of galaxies. Unlike supernovae or other methods such as cluster of galaxy counts, weak lensing tomography is purely based on geometry and does not depend on knowledge of the physics of the objects used as distance indicators. In addition, the reason for analyzing observations in the direction of clusters is that the shear signal is enhanced by about 10 over the field. Our work will eventually contain results obtained on 91 rich clusters from the HST archive combined with ground based work to obtain photo-zs. This combination of photo-z and weak lensing tomography will enable us to constrain the equation of state of dark energy. We present here the latest results obtained so far in this study.

    2011-12-01

    The study is designed to provide an informal summary of what is known about consumer switching of health insurance plans and to contribute to knowledge about what motivates consumers who choose to switch health plans. Do consumers switch plans largely on the basis of critical reflection and assessment of information about the quality, and price? The literature suggests that switching is complicated, not always possible, and often overwhelming to consumers. Price does not always determine choice. Quality is very hard for consumers to understand. Results from a random sample survey (n = 2791) of the Alkmaar region of the Netherlands are reported here. They suggest that rather than embracing the opportunity to be active critical consumers, individuals are more likely to avoid this role by handing this activity off to a group purchasing organization. There is little evidence that consumers switch plans on the basis of critical reflection and assessment of information about quality and price. The new data reported here confirm the importance of a group purchasing organizations. In a free-market-health insurance system confidence in purchasing groups may be more important for health insurance choice than health informatics. This is not what policy makers expected and might result a less efficient health insurance market system.

    Objectives/Hypothesis To gather qualitative and semiquantitative information about catastrophic complications during and following tracheotomy. Study Design National survey distributed to American Academy of Otolaryngology–Head and Neck Surgery members via the Academy weekly email newsletter during April and May 2011. Methods A total of 478 respondents provided estimates of the number of four specific tracheotomy-related complications (innominate artery fistula, esophageal fistula, acute tracheotomy occlusion, and obstructing granuloma), all catastrophic events, and events resulting in death or permanent disability encountered during their careers. There were 253 respondents who provided 405 free-text descriptions of specific events. Results The respondents experienced approximately one catastrophic event every 10 years and one event resulting in death or permanent disability every 20 years. More than 90% occurred more than 1 week after surgery. Categories of physicians who experienced more events per year included academic physicians and laryngologists. Pediatric otolaryngologists had twice as many innominate artery fistulas per year of practice as others. Qualitative (free-text) descriptions of the most serious events demonstrated that more of these events involved loss of airway and volume bleeds, usually from innominate or carotid artery erosion. Many of the events due to airway loss involved potentially correctable deficits in family education, nursing care, home care, and other structural factors. Conclusions Even when we allow for selection bias, these data suggest that a substantial number of tracheotomy complications leading to death or permanent disability occur at a national level. The vast majority of events occur more than 1 week after the procedure. Many of the described events were caused by factors that should be amenable to prospective system improvement strategies.

    2017-06-01

    Full Text Available In recent decades, academics and practitioners started a deep discussion about the limitations and perspectives of enterprise budgeting systems. Traditional budgets are frequently criticized due to their inflexibility, weak connection to corporate performance and demand on manager’s time. Recently, we have observed more frequent examples of firms which have undertaken budgeting system transformation and the adoption of modern, flexible and performance-based budgets. In this study, we have studied some trends in the budgeting of Czech firms with a focus on the manager´s behaviour. This paper contributes to the existing knowledge in two fields: Firstly, it summarizes the existing state of the art regarding the budgeting transformation; secondly, it presents the survey results focused on the operational budget utilization and its impact on the manager’s behaviour. Overall, the study presents some findings regarding the impact of an operational budget on the manager’s behaviour. We have tested how frequently situations occur, more specifically those frequently discussed in literature, in a given Czech firm´s budgeting practices.

    Chronic migraine is a costly and highly disabling condition that impacts millions of people in the United States. While chronic migraine is hypothesized to result from more infrequent forms of migraine, the precise mechanism by which this develops is still being researched. This study sought to better characterize the treatment patterns, disorder characteristics, and medical and disability profile of the chronic migraine population using the largest dataset of chronic migraineurs ever collected. The survey was started by 8,359 individuals and 4,787 met the inclusion criteria for diagnosed chronic migraine The number of stressful life events participants experienced due to their migraines related to number of therapies tried (pmigraineurs may misattribute aspects of psychiatric or medical comorbidities to their chronic migraines. Further, the sample underutilized mental health services and were unsatisfied with their migraine treatments. Providers to chronic migraineurs should ensure that patients are receiving appropriate mental health care in order to alleviate psychological distress as well as to potentially lessen negative life events previously associated with migraine symptoms.

    The Herschel Orion Protostar Survey (HOPS) is an ongoing 200-hour open-time key project with the Herschel Space Observatory to study protostars in the Orion molecular cloud complex. HOPS is obtaining PACS 70 and 160 micron imaging of 286 Orion protostars and PACS spectroscopy of a subset of 36, sampling the expected peaks of their spectral energy distributions (SEDs). The Herschel data are complemented by Spitzer 3-24 micron photometry and 5-40 micron spectroscopy, high angular resolution near-IR imaging with Hubble and ground-based telescopes, and millimeter observations of the surrounding gas. With these combined data we can determine the fundamental properties (multiplicity, gas infall rate, bolometric luminosity, outflow cavity geometry) of a large sample of protostars in a single cloud complex. With far-IR imaging and 1.6-160 micron SEDs for 171 protostars and 55-200 micron spectroscopy for 10 protostars expected to be in hand by mid-March 2011, we will present a selection of recent results.

    Mental health authorities must know the public's attitude to community psychiatry when planning community mental health services. However, previous studies have only investigated the impact of demographic variables on the attitude to community psychiatry. To assess the influence of psychological and sociological parameters on the public opinion of community psychiatry in Switzerland. Linear regression analyses of the results of a public opinion survey on a representative population sample in Switzerland (n = 1737). Most respondents have positive attitudes to community psychiatry. In the regression analysis (R2 adjusted = 21.2%), negative emotions towards mentally ill people as depicted in the vignette, great social distance, a positive attitude to restrictions, negative stereotypes, high rigidity and no participation in community activities significantly influenced negative attitudes to community psychiatry. Additionally, other parameters, e.g. contact with mentally ill people and the nationality of the interviewee, have a significant influence. In planning psychiatric community services, general individual traits and emotive issues should be considered because they influence the response towards community psychiatry facilities in the host community.

    Providing an evidence basis for voice therapy in the German-speaking countries faces the challenge that-for historical reasons-a variety of direct voice therapy methods is available. The aim of this study was to clarify which therapy methods are chosen and the underlying principles for this selection. An online survey was implemented to identify to what extent the variety of methods described in theory is also applied in practice. A total of 434 voice therapists in Germany, Austria, and Switzerland were asked, among other things, which methods they prefer. A significant majority of therapists do not apply one specific method but rather work with a unique combination of direct voice therapy methods for individual clients. These results show that the variety of methods described in the literature is also applied in voice therapy practice. The combination of methods becomes apparent during the choice of exercises. The type of voice disorder plays no decisive role in the method selection process, whereas certain patient variables do have an influence on this process. In particular, the patients' movement restrictions, their state of mind or mood on a given day, and aspects of learning theory are taken into account. The results suggest that a patient-oriented selection of appropriate exercises is of primary importance to voice therapists and that they rarely focus on specific direct voice therapy methods. It becomes clear that an evaluation of single methods does not correspond to practical experience, and therefore, an overall evaluation of voice therapy appears to be more useful. Copyright © 2015.

    Full Text Available Abstract Background The Breast Health Surveys, conducted by the National Breast Cancer Centre (NBCC in 1996 and 2003, are designed to gain insight into the knowledge, attitudes and behaviours of a nationally representative sample of Australian women on issues relevant to breast cancer. In this article, we focus on major aspects of the design and present results on respondents' knowledge about mammographic screening. Methods The 2003 BHS surveyed English-speaking Australian women aged 30–69 without a history of breast cancer using computer-assisted telephone interviewing. Questions covered the following themes: knowledge and perceptions about incidence, mortality and risk; knowledge and behaviour regarding early detection, symptoms and diagnosis; mammographic screening; treatment; and accessibility and availability of information and services. Respondents were selected using a complex sample design involving stratification. Sample weights against Australian population benchmarks were used in all statistical analyses. Means and proportions for the entire population and by age group and area of residence were calculated. Statistical tests were conducted using a level of significance of 0.01. Results Of the 3,144 respondents who consented to being interviewed, 138 (4.4% had a previous diagnosis of breast cancer and were excluded leaving 3,006 completed interviews eligible for analysis. A majority of respondents (61.1% reported ever having had a mammogram and 29.1% identified mammography as being the best way of finding breast cancer. A majority of women (85.9% had heard of the BreastScreen Australia (BSA program, the national mammographic screening program providing free biennial screening mammograms, with 94.5% believing that BSA attendance was available regardless of the presence or absence of symptoms. There have been substantial gains in women's knowledge about mammographic screening over the seven years between the two surveys. Conclusion The

    There are barely any studies focusing on migration in relation to mental illness stigma. We explore present attitudes regarding depression among migrants (either born in Germany or born abroad) and non-migrants in Germany, drawing upon three components of public stigma: stereotypes, emotional reactions and desire for social distance. Furthermore, differences in self-stigma of depression between the two groups are analyzed. Analyses are based on a representative telephone survey (N = 2013) in Germany. Respondents were presented with a vignette depicting either someone from Turkey or from Germany affected by depression, followed by questions on stereotypes, emotional reactions and desire for social distance. The (anticipated) self-stigma of depression was also assessed. Analyses of variance tested for differences between migrant and non-migrant respondents, stratified by migrant status in the vignette. Regarding the depression vignette depicting a non-migrant, there were only few differences between subgroups. However, when presented with a vignette describing someone from Turkey, respondents with migrant background who were foreign-born expressed greater stigmatizing attitudes, e.g. when it comes to stereotypes or desire for social distance. Furthermore, this subsample displayed higher levels of self-stigma of depression, especially regarding the ascription of own responsibility. The results underline the need to incorporate migration status/ethnicity in stigma research. Differences in attitudes as well as in (anticipated) self-stigma of depression identify foreign-born migrants in Germany as important target groups for tailored anti-stigma interventions, which need to consider diverse cultural backgrounds.

    We began a systematic study of primitive bodies, called S(3OS^2) , Small Solar System Objects Spectroscopic Survey. Among the objects we are studying are: Near-Earth objects, asteroid families, asteroids near resonances, dark objects, Centaurs, objects representing a possible transition comet-asteroid, and asteroids with a very slow or complex rotation. The chemical and mineralogical composition of an asteroid's surface is studied through the analysis of its reflectance spectra in different wavelenghts. Four observation missions were carried out at the European Southern Observatory (La Silla, Chile), when we obtained a mineral characterization of about 300 asteroids. The observations were realized with a 1.52 m telescope with a Boller & Chivens spectrograph and a 2048x2048 CCD. The spectra were obtained in wavelenghts from 3000 to 9200 { Angstroms} and were reduced using the IRAF reduction package with usual techniques like flat-field, He-Ar lamps and solar analogs. Concerning concentrations in the Main Belt due to resonances with Jupiter, we present the initial results of Cybeles, Hildas, Hungarias, NEAs and Phocaea. We observed also, along all its opposition, the Centaur object 2060 Chiron, that displays a small cometary activity represented by variations in its reflectance spectrum. Concerning asteroid families, concentrations we believe are debris of an energetic collision causing the total breakup of the original bodies, we observed members of Adeona, Dora, Eos, Eunomia, Flora, Merxia and Themis. The Main Belt is represented in our sample by Flora, in the most inner region, Eunomia, Adeona, Dora and Merxia in the intermediary region, and Themis and Eos representing the most outer region of the belt. *Based on observations made with the 1.52 m telescope at the European Southern Observatory (La Silla, Chile) under the agreement with the CNPq/Observatorio Nacional (Brazil).

    "Infrastructure" is the buzzword that emerged from the 1997 HIMSS/Hewlett-Packard Leadership Survey. Of the 1,220 survey respondents, 37 percent identified upgrading infrastructure as the most significant IT projects their organizations undertook over the last year. "In the past, organizations were not deliberately against building infrastructure; they just did not know what it takes," says researcher and survey analyst John Pollock, Princeton, N.J. "It is evident now they are looking more at the framework." Increasing pressure to achieve a competitive advantage has led to a real interest in integrating healthcare delivery systems, he explains.

    Pipeline operators worldwide have implemented integrity management programs in an effort to improve operation and maintenance efficiency along with continued safe operation of pipeline systems. Several types of monitoring and data collection activities are incorporated into these programs, with in line inspection (ILI) tools providing data for detection and quantification of features that may impact the integrity of the pipeline system. Magnetic flux leakage (MFL) ILI tools are among the most widely used in pipeline systems. Primarily used for metal loss detection and quantification, these tools are extremely robust, performing successfully in the harsh environments found in operating pipelines, with the majority of MFL tools in service today relying upon axially oriented magnetic fields. For feature classes whose principal axis is aligned parallel to the pipe axis, the use of an axially applied magnetic field may quite often result in decreased performance due to difficulties in detection and sizing. Through the use of fields applied either perpendicular or in an oblique direction to the principal axis, the magnetic leakage levels generated at feature locations are increased, providing usable signal levels. When used concurrently with an axially oriented magnetizer, an obliquely applied magnetic field may provide the ability to detect, quantify, or otherwise aid in discrimination of volumetric versus non-volumetric features. Providing the ability to collect both of these data sets in a single survey would allow operators to minimize the number of surveys required to address all categories of metal loss features that may be present within pipeline systems. This paper will discuss some of the variables that affect detection and sizing of metal loss zones with respect to the applied field direction, including graphs and tables to quantify the effects of angular displacement for specific feature shapes. Several classes of features have been chosen for evaluation

    2016-10-01

    The research describes an extensible method of evaluating and cancelling electronic journals during a budget shortfall and evaluates implications for interlibrary loan (ILL) and user satisfaction. We calculated cost per use for cancellable electronic journal subscriptions (n=533) from the 2013 calendar year and the first half of 2014, cancelling titles with cost per use greater than $20 and less than 100 yearly uses. For remaining titles, we issued an online survey asking respondents to rank the importance of journals to their work. Finally, we gathered ILL requests and COUNTER JR2 turnaway reports for calendar year 2015. Three hundred fifty-four respondents completed the survey. Because of the level of heterogeneity of titles in the survey as well as respondents' backgrounds, most titles were reported to be never used. We developed criteria based on average response across journals to determine which to cancel. Based on this methodology, we cancelled eight journals. Examination of ILL data revealed that none of the cancelled titles were requested with any frequency. Free-text responses indicated, however, that many value free ILL as a suitable substitute for immediate full-text access to biomedical journal literature. Soliciting user feedback through an electronic survey can assist collections librarians to make electronic journal cancellation decisions during slim budgetary years. This methodology can be adapted and improved upon at other health sciences libraries.

    "Formation and early growth of BH' and "Accretion by supermassive BH through cosmic time' are two of the scientific objectives of the Athena mission. To these and other topics (i.e. first galaxy groups, cold and warm obscuration and feedback signatures in AGN at high z), a large fraction (20-25%) of the Athena Mock Observing Plan is devoted, in the form of a multi-tiered (deep-medium-wide) survey with the WFI. We used the flexible SIXTE simulator to study the impact of different instrumental configurations, in terms of WFI FOV, mirror psf, background levels, on the performance in the three layers of the WFI survey. We mainly focus on the scientific objective that drives the survey configuration: the detection of at least 10 AGN at z=6-8 with Log(LX)=43-43.5 erg/s and 10 at z=8.10 with Log(LX)=44-44.5 erg/s. Implications for other scientific objectives involved in the survey are also discussed.

    2000-06-01

    The year 2000 represents the 10th anniversary of the Retirement Confidence Survey (RCS), and the third year for the Minority RCS and Small Employer Retirement Survey (SERS). Key RCS findings over the past 10 years include: The fraction of workers saving for retirement has trended upward, and today 80 percent of households report that they have begun to save. The fraction of workers who have attempted to calculate how much they need to save for retirement has risen noticeably over the past several years. Today, 56 percent of households report that they have attempted the calculation. One-half of workers who have attempted such a calculation report that it has changed their behavior, such as saving more and/or changing where they invest their retirement savings. Workers who have done the calculation appear to be in better shape regarding their retirement finances. Worker confidence in the ability of Social Security to maintain benefit levels bottomed out in 1994 and 1995. Workers today are just as confident as they were in 1992, although the majority remain not confident in Social Security. Regarding overall retirement confidence, Hispanic-Americans tend to be the least confident among the surveyed minority groups that they will have enough money to live comfortably throughout their retirement years. Key SERS findings include: While cost and administrative issues do matter to small employers, they are not the primary reasons for low plan sponsorship rates. Employee-related reasons are most often cited as the most important factor for not offering a retirement plan. Business-related reasons, such as profitability, are also a main decision-driver. It is important to note what small employers without plans do not know about plan sponsorship. Small employers that do sponsor a retirement plan report that offering a plan has a positive impact on both their ability to attract and retain quality employees and the attitude and performance of their employees.

    For the study of a landslide that occurred at Hachimantai Sumikawa, Akita Prefecture, an airborne electromagnetic survey is conducted for the examination of the relationship between the spot of landslide and solfataric clay (bluish gray clay). The location is a cap block type structure with a Neogene green tuff overlain by accumulated lava flow, where hot water is very active. The system used in this study is capable of measurement across a very wide frequency range, and measurements are made simultaneously at five frequencies of 220Hz, 1100Hz, 5500Hz, 27,500Hz, and 137,500Hz, these frequencies meaning depth levels 5m-70m explored. It is found that the spot of landslide matches a region where resistivity is so low as to be not higher than 10ohm/m. It is also found, in the resistivity cross section analysis for the middle part of the spot of landslide, that the mass of soil that moved on the upper part of the spot is relatively high in resistivity while the part below the slide surface is low in resistivity. There is agreement between the results reported above and the results of on-site investigations. 4 refs., 6 figs.

    A survey into women's experiences of giving birth in the UK published in October 2013, provides a useful insight (Birthrights UK 2013). It is the first of its kind to capture women's views on dignity in childbirth. The survey reflects the importance of place of birth, with women who gave birth in obstetric units reporting much lower levels of satisfaction and a greater lack of control than those giving birth in birth centres or at home. Those who had an instrumental birth reported lower levels of respectful care and a much greater lack of control. The midwifery profession needs to reflect carefully on these findings and ensure the needs of running a busy maternity service efficiently do not take priority over the human rights of women.

    2016-12-01

    The World Federation of Public Health Associations' Oral Health Working Group (WFPHA OHWG) carried out a survey to establish the extent of global dental public health (DPH) capacity. Senior stakeholders in DPH completed 124 surveys, covering 73 countries and all WHO regions. The survey evaluated DPH workforce within the country, funding, education, current services, and integration between public health and DPH in countries across the world. In 62 per cent of countries, DPH is only partially integrated in the public health system, while in 25 per cent of countries it has not yet been formally integrated. DPH programs at Masters level are available in 44 per cent of countries. Over half of countries have 0 to 10 trained DPH professionals. Because both poor oral and general health share several common risk factors, DPH must be integrated into national health systems and budgets, with an emphasis on having trained DPH specialists available in every country to collaborate in healthcare policy and provision.

A random survey of 1,000 local residents, from all administrative regions of Armenia, concerned with health care services cost and satisfaction was conducted. Participation in the survey was voluntary and the information was collected using anonymous telephone interviews. The utilization of health care services was low, particularly in rural areas. This under-utilization of services correlated with low income of the population surveyed. The state funded health care services are inadequate to ensure availability of free-of-charge services even to economically disadvantaged groups. Continued reliance on direct out-of pocket and illicit payments, for medical services, are serious issues which plague healthcare, pharmaceutical and medical technology sectors of Armenia. Restructuring of the health care system to implement a cost-effective approach to the prevention and treatment of diseases, especially disproportionately affect the poor, should be undertaken. Public payments, increasing the amount of subsidies for poor and lower income groups through a compulsory health insurance system should be evaluated and included as appropriate in this health system redesign. Current medical services reimbursement practices undermine the principle of equity in financing and access. Measures designed to improve healthcare access and affordability for poor and disadvantaged households should be enacted.

    The Arecibo 327 MHz drift pulsar survey (AO327) has operated since 2010 and aims to cover the entire Arecibo sky (declinations of -1 to 38 degrees). We present details on the progress of the survey and a new set of discoveries over the past year. Phase 1 of AO327 targets declinations of -1 to 28 degrees and is 55% complete; Phase 2 will target declinations of 28 to 38 degrees. The survey is expected to be completed in 2017. Out of a total of 28 new pulsars, 12 were found in 2013, including three millisecond pulsars. PSR J2234+06 has a rotation period of 3.58 ms and is in a 32-day orbit in a binary system with a white dwarf companion. This pulsar is bright and a very stable rotator, making it suitable for inclusion in Pulsar Timing Arrays. The orbit of J2234+06 has an eccentricity of 0.13, which cannot be accounted for by stellar evolution but may be explained by an origin in a subsequently disrupted hierarchical triple, or by an exchange interaction. PSR J0509+08 has a period of 4.06 ms and is in a 4.9-day binary system with a white dwarf companion. This pulsar is also a candidate for inclusion in PTAs.

    The Japanese Society of Radiological Technology asked radiation workers about the radiation doses and the state of their health as well as family. The reports by the Health and Welfare Ministry were referenced to compare radiation workers with others. The questionnaire was sent to about 4,000 members, and returned from 2,479. The survey showed that 684 persons (27.6%) felt health anxiety, 455 persons (18.4%) had medical check for recent one year, and 1,645 persons (66.4%) had anamnesis. Radiation doses for one year and cumulated doses varied according to engaging duration. (K.H.)

    The Army acquisition community currently uses a dedicated, point-to-point secure computer network for the Army Material Plan Modernization (AMPMOD). It must transition to the DOD supplied Defense Secure Network 1 (DSNET1). This is one of the first networks of this size to begin the transition. The type and amount of computing resources available at individual sites may or may not meet the new network requirements. This task surveys these existing telecommunications resources available in the Army acquisition community. It documents existing communication equipment, computer hardware, associated software, and recommends appropriate changes.

    Participation in competitive bicycling has increased substantially over the past decade, and bicycle injuries have increased accordingly. Cycling has been reported in several studies to have higher rates of injury than other sports and recreational activities; accordingly, riders must be cognizant of the potential for injury and protect themselves appropriately. The purpose of the current study was to survey an established competitive Los Angeles-based road cycling team to determine the epidemiology of and circumstances for traumatic cycling injuries.

    The purpose of this study was to determine pediatric dentists' level of job satisfaction and to explore which factors (demographic and practice/work/patient characteristics) are related to their satisfaction. Data were collected with mailed surveys from 385 and with web-based surveys from 966 pediatric dentists in the United States. Professional satisfaction was measured with the Professional Satisfaction Scale and the Dentists' Satisfaction Scale. Most respondents would choose dentistry (89 percent) and pediatric dentistry (92 percent) again and would recommend dentistry (85 percent) and pediatric dentistry (83 percent) to their child as a career. Male respondents were more satisfied with income, personal and professional time, staff, and practice management aspects, and female respondents were more satisfied with patient relations. The older the dentists were, the more satisfied they were. Respondents in academia were less stressed and less satisfied with their income than respondents in nonacademic settings. The more time spent in the operatory and the less administrative work, the more satisfied the respondents were. The fewer patients from a lower socioeconomic background they treated, the more satisfied they were. Overall, pediatric dentists have a high level of job satisfaction. Demographic factors and practice/work/patient characteristic are related to job satisfaction.

  8. Dark Energy Survey Year 1 Results: Weak Lensing Shape Catalogues

    2017-08-04

    We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 square degrees with a median redshift of $0.59$. The catalogues cover two main fields: Stripe 82, and an area overlapping the South Pole Telescope survey region. We describe our data analysis process and in particular our shape measurement using two independent shear measurement pipelines, METACALIBRATION and IM3SHAPE. The METACALIBRATION catalogue uses a Gaussian model with an innovative internal calibration scheme, and was applied to $riz$-bands, yielding 34.8M objects. The IM3SHAPE catalogue uses a maximum-likelihood bulge/disc model calibrated using simulations, and was applied to $r$-band data, yielding 21.9M objects. Both catalogues pass a suite of null tests that demonstrate their fitness for use in weak lensing science. We estimate the 1$\\sigma$ uncertainties in multiplicative shear calibration to be $0.013$ and $0.025$ for the METACALIBRATION and IM3SHAPE catalogues, respectively.

    An online survey utilizing Survey Monkey linked through the American Association of Zoo Veterinarians listserve examined current practices in megavertebrate analgesia. Data collected included drugs administered, dosing regimens, ease of administration, efficacy, and adverse events. Fifty-nine facilities (38 housing elephants, 33 housing rhinoceroses) responded. All facilities administered nonsteroidal anti-inflammatory drugs (NSAIDs), with phenylbutazone (0.25-10 mg/kg) and flunixin meglumine (0.2-4 mg/kg) being most common. Efficacy was reported as "good" to "excellent" for these medications. Opioids were administered to elephants (11 of 38) and rhinoceroses (7 of 33), with tramadol (0.5-3.0 mg/kg) and butorphanol (0.05-1.0 mg/kg) being most common. Tramadol efficacy scores were highly variable in both elephants and rhinoceroses. While drug choices were similar among institutions, substantial variability in dosing regimens and reported efficacy between and within facilities indicates the need for pharmacokinetic studies and standardized methods of analyzing response to treatment to establish dosing regimens and clinical trials to establish efficacy and safety.

    The exposure to engineered nanomaterials (ENMs) is a new emerging risk at work due to an increase in the number of workers potentially exposed to them and the current lack of data on their health and safety risks. This paper reports the findings of a survey designed to study the safety practices employed by workers in Spanish research facilities performing tasks involving the use of ENMs at research level. A questionnaire pretested and validated by an expert panel was sent by e-mail to the target audience. The 425 surveys completed show that most of the respondents handled up to 5 different ENMs, in suspension, in small amounts during short periods of exposure. The implementation of common hygienic practices, such as the use of protection for hands and the implementation of fume hoods, is widely indicated. The selection of the preventive and protective measures does not depend on the characteristics of ENMs handled. Also, the risks posed by ENMs are widely ignored. Besides the performance of risk assessment, hygienic monitoring and the conducting of a specific health surveillance are practically non-existent although some accidents relating to ENMs were identified. In conclusion, workers' exposure to ENMs seems to be low. Even though the best practices and preventive and protective measures reported were employed, most of the respondents could not be correctly protected. Moreover, workers do not associate the measures implemented with the nanorisks. Finally, there is a lack of proactive action underway to protect the workers, and concerns about safety are weakly evidenced.

    To support integration of occupational therapy in primary care and research in this area, it is critical to document examples of occupational therapy in primary care. This study describes occupational therapy roles and models of practice used in primary care. An electronic survey was sent to occupational therapists across Canada. Participants were identified using purposive and snowball sampling strategies. Descriptive statistics were used to analyze the data. Respondents (n = 52) were almost exclusively working on interprofessional teams. Intervention was provided most frequently to individual clients, and services were provided both within the home/community and in the clinic. Occupational therapists offered a range of health promotion and prevention services, predominantly to adults and older adults. A number of supports and barriers to the integration of occupational therapy were identified. A growing number of occupational therapists are working in primary care providing a broad range of services across the life span. © CAOT 2016.

    Tuberculosis affected about 8.5 million patients in 2011. Numerous efforts are needed to reduce the pool of individuals with latent TB infection (LTBI). The aim of the study was to describe a tuberculin skin testing (TST) survey carried out in Albania to estimate the LTBI burden; furthermore, knowledge of TB was evaluated through an ad hoc questionnaire. A TST survey was performed in three geographical districts of Albania: Tirana-Kamez, Vlora, and Dibra. Cluster sampling was carried out of young Albanian students. In addition, the same students were given a questionnaire to assess their knowledge, attitudes, and any misconceptions about TB. The mean (standard deviation) age of the individuals, according to their educational level, was the following: grade five, 11.03 (0.18) years; grade six, 12.02 (0.17) years; and grade seven, 13.02 (0.16) years. The TST induration size was read in 4,648 students. About 5.0% showed a reaction >5 mm, with a significant variability in the districts selected (12.1% in the district of Dibra). An induration diameter >15 mm was found mainly in those areas with high TB incidence (i.e., Tirana-Kamez and Dibra). About 13% of the students had no knowledge of TB. LTBI prevalent cases are estimated to be low in Albania, although there are areas where the TB management should be improved to reduce the probability of Mycobacterium tuberculosis transmission. The level of knowledge about TB disease is inadequate and new public health strategies should be implemented, focusing on educational TV programs.

    To assess the effect of neurology residency education as trainees advance into independent practice, the American Academy of Neurology (AAN) elected to survey all graduating neurology residents at time of graduation and in 3-year cycles thereafter. A 22-question survey was sent to all neurology residents completing residency training in the United States in 2007. Of 523 eligible residents, 285 (54.5%) responded. Of these, 92% reported good to excellent quality teaching of basic neurology from their faculty; however, 47% noted less than ideal training in basic neuroscience. Two-thirds indicated that the Residency In-service Training Examination was used only as a self-assessment tool, but reports of misuse were made by some residents. After residency, 78% entered fellowships (with 61% choosing a fellowship based on interactions with a mentor at their institution), whereas 20% entered practice directly. After adjustment for the proportion of residents who worked before the duty hour rules were implemented and after their implementation, more than half reported improvement in quality of life (87%), education (60%), and patient care (62%). The majority of international medical graduates reported wanting to stay in the United States to practice rather than return to their country of residence. Neurology residents are generally satisfied with training, and most entered a fellowship. Duty hour implementation may have improved resident quality of life, but reciprocal concerns were raised about impact on patient care and education. Despite the majority of international trainees wishing to stay in the United States, stricter immigration laws may limit their entry into the future neurology workforce.

    A method based on second order sliding mode control (2-SMC) is proposed to design controllers for a small quadrotor UAV. For the switching sliding manifold design, the selection of the coefficients of the switching sliding manifold is in general a sophisticated issue because the coefficients are nonlinear. In this work, in order to perform the position and attitude tracking control of the quadrotor perfectly, the dynamical model of the quadrotor is divided into two subsystems, i.e., a fully actuated subsystem and an underactuated subsystem. For the former, a sliding manifold is defined by combining the position and velocity tracking errors of one state variable, i.e., the sliding manifold has two coefficients. For the latter, a sliding manifold is constructed via a linear combination of position and velocity tracking errors of two state variables, i.e., the sliding manifold has four coefficients. In order to further obtain the nonlinear coefficients of the sliding manifold, Hurwitz stability analysis is used to the solving process. In addition, the flight controllers are derived by using Lyapunov theory, which guarantees that all system state trajectories reach and stay on the sliding surfaces. Extensive simulation results are given to illustrate the effectiveness of the proposed control method. Copyright © 2014 ISA. Published by Elsevier Ltd. All rights reserved.

    This ongoing pan-European patient survey is being conducted to explore how chronic pain patients perceive their condition and the coping strategies they use to help deal with the pain. Participating doctors - general practitioners (GPs), pain specialists and orthopaedists - selected patients suffering from chronic pain who routinely visited their practices. Doctors provided details of individual pain diagnoses and treatment which were entered into a questionnaire. Each patient then answered additional questions about pain experience, pain therapy, possible areas for improvement and any coping strategies used. Completed questionnaires were sent to a healthcare-focused global consultancy for analysis and evaluation. The most common diagnosis was chronic back pain, in 61% of the 6435 patients. Using a five-point verbal rating scale (VRS), 70% of participants rated the intensity of their pain as moderate or severe. Approximately half were receiving monotherapy. The more intense the pain was, the higher the percentage of patients receiving combination therapy. The most frequently used combinations were NSAIDs/non-opioids with weak or strong opioids. Approximately two out of three patients received non-pharmacological treatment in addition to their pain medication. Almost all the patients (90%) perceived their pain intensity to be higher than it should be under successful pain management, and 30% were dissatisfied with their current treatment. Insufficient pain relief was the reason in most cases, but 29% of dissatisfied responders cited the side effects of medication. About half the patients identified a medium to high need for improvement in their ability to work, sleep and carry out general activities. For each specialisation, the more severe the pain, the fewer patients who were satisfied with their current pain treatment. More patients with severe and extreme pain were satisfied with treatment by a pain specialist than with a GP or orthopaedist. For all three

    In Europe more than 50% of asthmatic treated patients have not well-controlled asthma. Asthma affects about 2.5 million of patients in Italy. The present survey aims at investigating how Italian allergists approach asthmatic patients, in order to highlight pitfalls and unmet needs concerning real-life asthma management. An anonymous 16 item web questionnaire was available (April-October 2015) to all allergists who visited the web site of SIAAIC (Società Italiana di Allergologia, Asma Immunologia Clinica). Those who wished to give their contribution had the opportunity to answer about epidemiology, risk factors, treatment approaches, and adherence to therapy. One hundred and seventy four allergists answered the survey. 54% of them reported up to 10 patient visits per week and 35.3% between 10 and 30. The most frequent reasons of follow up visits are routine check-up (56.5% of allergists), and worsening of symptoms (41% of allergists). Nocturnal apnoeas, gastro-esophageal reflux and obesity are the most important comorbidities/risk factors of poorly controlled asthma. Bronchial hyper-responsiveness, increased NO levels and reduced exercise tolerance are the most important indicators of asthma severity. Concerning therapy, ICS combined with LABA is the treatment of choice suitable for the majority of patients. A rapid onset of action and a flexible ICS dosage are indicated as the optimal characteristics for achieving the therapeutic goals. Poor adherence to therapy is an important reason for symptom worsening for the majority of allergists. Complex dosage regimens and economic aspects are considered the most important factors impacting on adherence. Allergists are involved in the management of asthma, regularly seeing their patients. Co-morbidities are frequent in asthmatic patients and may impact negatively on disease control, thus identifying patients who need a more careful and strict monitoring. Airway hyper-responsiveness to methacholine challenge test and

    Current research on Internet addiction (IA) reported moderate to high prevalence rates of IA and comorbid psychiatric symptoms in users of social networking sites (SNS) and online role-playing games. The aim of this study was to characterize adult users of an Internet multiplayer strategy game within a SNS. Therefore, we conducted an exploratory study using an online survey to assess sociodemographic variables, psychopathology, and the rate of IA in a sample of adult social network gamers by Young's Internet Addiction Test (IAT), the Toronto Alexithymia Scale (TAS-26), the Beck Depression Inventory-II (BDI-II), the Symptom Checklist-90-R (SCL-90-R), and the WHO Quality of Life-BREF (WHOQOL-BREF). All participants were listed gamers of "Combat Zone" in the SNS "Facebook." In this sample, 16.2% of the participants were categorized as subjects with IA and 19.5% fulfilled the criteria for alexithymia. Comparing study participants with and without IA, the IA group had significantly more subjects with alexithymia, reported more depressive symptoms, and showed poorer quality of life. These findings suggest that social network gaming might also be associated with maladaptive patterns of Internet use. Furthermore, a relationship between IA, alexithymia, and depressive symptoms was found that needs to be elucidated by future studies.

    Currently, there are clear indications that due to their exposed occupational position psychiatrists and psychotherapists are at a higher risk than the general public to become the victim of stalking by patients. This study investigated the frequency of stalking and its psychosocial impact among psychiatrists and psychotherapists in the Federal Republic of Germany. Analysis of an online survey among members of the German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) from 23 September 2015 until 22 October 2015. Of the respondents 26.5% reported having been the victim of stalking. In more than a third of the reported cases the stalking was described as severely or very severely debilitating. The majority of the perpetrators suffered from psychotic or personality disorders. Male victims were significantly more frequently stalked by a female perpetrator. Approximately 1 in 10 stalking victims continued the treatment of the perpetrator. The majority of the stalking victims did not obtain substantial support from their employer. The phenomenon of stalking within therapeutic relationships needs to be incorporated into the medical and psychotherapeutic professional training, e. g. by implementing specialized training courses and the systematic integration of this topic into clinical supervision. The institutional dealing with stalking by patients needs to optimized, e. g. by promptly transferring treatment of patients who stalk to other professionals and, where required, providing assistance in reporting stalking incidents to the police.

    Transition and transfer to adult-oriented health care is an important yet challenging task for adolescents and young adults with chronic medical conditions. Transition practices vary widely, but a paucity of data makes determination of best practices difficult. We described North American pediatric gastroenterologists' preferences and present transition practice patterns and explored whether experience affected providers' perspectives. An online survey was distributed via e-mail to members of the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition. Participation was voluntary and answers were anonymous. Quantitative and qualitative analysis was performed. Almost three quarters of the 175 respondents describe providing transition or self-care management education, but only 23% use structured readiness assessments. Most respondents (88%) report having age cutoffs above which they no longer accept new referrals, with the most common age being 18 years (57%). One third report the ability to provide age-appropriate care to patients older than 21 years. Only 6% indicate that their practice or institution should provide care for individuals older than 25 years. Many (63%) indicate that their practice or institution has a policy regarding age of transfer, but most (79%) are flexible. Provider preferences for triggers to transfer to adult care diverge widely between age, milestones, and comorbidities. Overall, parent (81%) and patient (74%) attachment to pediatric health care providers are cited as the most common barriers to transition. Preferences and practices surrounding transition preparation and transfer to adult care vary widely, reflecting continued uncertainty regarding optimal transition strategies.

    Full Text Available The use of advanced technology in automobiles has increased dramatically in the past couple of years. Driver-assisting gadgets such as navigation systems, advanced cruise control, collision avoidance systems, and other safety systems have moved down the ladder from luxury to more basic vehicles. Concurrently, auto manufacturers are also designing and testing driving algorithms that can assist with basic driving tasks, many of which are being continuously scrutinized by traffic safety agencies to ensure that these systems do not pose a safety hazard. The research presented in this paper brings a third perspective to in-vehicle technology by conducting a two-stage survey to collect public opinion on advanced in-vehicle technology. Approximately 64 percent of the respondents used a smartphone application to assist with their travel. The top-used applications were navigation and real-time traffic information systems. Among those who used smartphones during their commutes, the top-used applications were navigation and entertainment.

Current gun owners were asked where and when they acquired their last firearm; if they purchased the firearm; and whether, as part of that acquisition, they had a background check (or were asked to show a firearm license or permit). 22% (95% CI, 16% to 27%) of gun owners who reported obtaining their most recent firearm within the previous 2 years reported doing so without a background check. For firearms purchased privately within the previous 2 years (that is, other than from a store or pawnshop, including sales between individuals in person, online, or at gun shows), 50% (CI, 35% to 65%) were obtained without a background check. This percentage was 26% (CI, 5% to 47%) for owners residing in states regulating private firearm sales and 57% (CI, 40% to 75%) for those living in states without regulations on private firearm sales. Potential inaccuracies due to recall and social desirability bias. 22% of current U.S. gun owners who acquired a firearm within the past 2 years did so without a background check. Although this represents a smaller proportion of gun owners obtaining firearms without background checks than in the past, millions of U.S. adults continue to acquire guns without background checks, especially in states that do not regulate private firearm sales.

    Open fractures are orthopaedic emergencies that carry a high risk for infection, non-union and soft tissue complications. Evidence-based treatment is impeded by the lack of high-quality evidence-based studies. The aim of this investigation was to elucidate the current practice of open fracture management in Germany and to determine major differences in treatment. Surgeons were asked to complete an online questionnaire consisting of 45 items developed by an expert consensus. The first part covered questions on general principles of open fracture management. The second part included questions on soft tissue management, the preferred method of initial surgical stabilisation, microbiological testing, employment of pulsatile lavage and local antibiotics, antibiotic regimen, second-look operations, and blood testing. Of 653 respondents, 364 (65 %) completed the first part and 314 (48 %) completed the second part of the online survey. 55 % answered that a standard operating procedure for the diagnosis and treatment of patients with open fractures exists in their hospital. Only 25 % leave pre-hospitalisation applied dressings intact until arrival of the patient in the operating room, and 40 % make this decision depending on information provided by pre-hospitalisation emergency personnel. 84 % participants exclude the use of antibiotic-coated implants in the treatment of open fractures. The favoured stabilisation method in Gustilo type I fractures is definitive internal osteosynthesis and primary wound closure for 61 % of respondents. In Gustilo type II (74 %) and type III fractures (93 %), temporary external fixation is preferred. High-pressure pulsatile lavage is used by 22 % responding surgeons in Gustilo type I fractures, 53 % for type II fractures and 67 % for type III fractures. Open fracture management differs considerably among surgeons in Germany. Further studies are needed to deliver high-quality evidence concerning primary fracture stabilisation, soft

  9. T-Slide Linear Actuators

    2009-01-01

    T-slide linear actuators use gear bearing differential epicyclical transmissions (GBDETs) to directly drive a linear rack, which, in turn, performs the actuation. Conventional systems use a rotary power source in conjunction with a nut and screw to provide linear motion. Non-back-drive properties of GBDETs make the new actuator more direct and simpler. Versions of this approach will serve as a long-stroke, ultra-precision, position actuator for NASA science instruments, and as a rugged, linear actuator for NASA deployment duties. The T slide can operate effectively in the presence of side forces and torques. Versions of the actuator can perform ultra-precision positioning. A basic T-slide actuator is a long-stroke, rack-and-pinion linear actuator that, typically, consists of a T-slide, several idlers, a transmission to drive the slide (powered by an electric motor) and a housing that holds the entire assembly. The actuator is driven by gear action on its top surface, and is guided and constrained by gear-bearing idlers on its other two parallel surfaces. The geometry, implemented with gear-bearing technology, is particularly effective. An electronic motor operating through a GBDET can directly drive the T slide against large loads, as a rack and pinion linear actuator, with no break and no danger of back driving. The actuator drives the slide into position and stops. The slide holes position with power off and no brake, regardless of load. With the T slide configuration, this GBDET has an entire T-gear surface on which to operate. The GB idlers coupling the other two T slide parallel surfaces to their housing counterpart surfaces provide constraints in five degrees-of-freedom and rolling friction in the direction of actuation. Multiple GB idlers provide roller bearing strength sufficient to support efficient, rolling friction movement, even in the presence of large, resisting forces. T-slide actuators can be controlled using the combination of an off

    We describe an ongoing search for pulsars and dispersed pulses of radio emission, such as those from rotating radio transients (RRATs) and fast radio bursts, at 350 MHz using the Green Bank Telescope. With the Green Bank Ultimate Pulsar Processing Instrument, we record 100 MHz of bandwidth divided into 4096 channels every 81.92 μs. This survey will cover the entire sky visible to the Green Bank Telescope (δ > –40°, or 82% of the sky) and outside of the Galactic Plane will be sensitive enough to detect slow pulsars and low dispersion measure (<30 pc cm{sup –3}) millisecond pulsars (MSPs) with a 0.08 duty cycle down to 1.1 mJy. For pulsars with a spectral index of –1.6, we will be 2.5 times more sensitive than previous and ongoing surveys over much of our survey region. Here we describe the survey, the data analysis pipeline, initial discovery parameters for 62 pulsars, and timing solutions for 5 new pulsars. PSR J0214+5222 is an MSP in a long-period (512 days) orbit and has an optical counterpart identified in archival data. PSR J0636+5129 is an MSP in a very short-period (96 minutes) orbit with a very low mass companion (8 M{sub J}). PSR J0645+5158 is an isolated MSP with a timing residual RMS of 500 ns and has been added to pulsar timing array experiments. PSR J1434+7257 is an isolated, intermediate-period pulsar that has been partially recycled. PSR J1816+4510 is an eclipsing MSP in a short-period orbit (8.7 hr) and may have recently completed its spin-up phase.

    Presents results of seismo-acoustic tests performed in the Marcel mine with the use of geophones installed in sprag probes, shield-sprag pipes on resin-grouted bolts. It was found that wall-spragged probes are the best method for installing geophones provided that hole depth is over 1 m. Geophones installed on bolts outside holes have the disadvantage of recording noise from the environment. The quality of recording was evaluated by comparing the signals obtained with signals gained from accelerometers, taking into consideration that geophones sense velocity while accelerometers sense acceleration. The recommendation is made that geophone installation quality be evaluated on the basis of the width of the frequency spectrum recorded. Spectrograms of the pulses recorded and their spectra (up to 7.5 kH) are presented. Geophones installed in shield-sprag pipes in shallow (80 cm) holes gave poor results. 1 ref.

    Full Text Available Abstract Background The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. Methods A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Results Analysis of 358 respondents (91% showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. Conclusions These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines.

  16. Universality of Wigner random matrices: a survey of recent results

    This is a study of the universality of spectral statistics for large random matrices. Considered are NxN symmetric, Hermitian, or quaternion self-dual random matrices with independent identically distributed entries (Wigner matrices), where the probability distribution of each matrix element is given by a measure {nu} with zero expectation and with subexponential decay. The main result is that the correlation functions of the local eigenvalue statistics in the bulk of the spectrum coincide with those of the Gaussian Orthogonal Ensemble (GOE), the Gaussian Unitary Ensemble (GUE), and the Gaussian Symplectic Ensemble (GSE), respectively, in the limit as N {yields} {infinity}. This approach is based on a study of the Dyson Brownian motion via a related new dynamics, the local relaxation flow. As a main input, it is established that the density of the eigenvalues converges to the Wigner semicircle law, and this holds even down to the smallest possible scale. Moreover, it is shown that the eigenvectors are completely delocalized. These results hold even without the condition that the matrix elements are identically distributed: only independence is used. In fact, for the matrix elements of the Green function strong estimates are given that imply that the local statistics of any two ensembles in the bulk are identical if the first four moments of the matrix elements match. Universality at the spectral edges requires matching only two moments. A Wigner-type estimate is also proved, and it is shown that the eigenvalues repel each other on arbitrarily small scales.

    Over the last 100,000??years, the U.S. Atlantic continental margin has experienced various types of mass movements some of which are believed to have taken place at times of low sea level. At one of these times of low sea level a significant trigger caused a major submarine mass movement off the coast of Virginia: the Currituck slide which is believed to have taken place between 24 and 50??ka ago. This slide removed a total volume of about 165??km3 from this section of the continental slope. The departure zone still shows a very clean surface that dips at 4?? and is only covered by a thin veneer of postglacial sediment. Multibeam bathymetric and seismic survey data suggest that this slide took place along three failures surfaces. The morphology of the source area suggests that the sediments were already at least normally consolidated at the time of failure. The slide debris covers an area as much as 55??km wide that extends 180??km from the estimated toe of the original slope. The back analysis of slide initiation indicates that very high pore pressure, a strong earthquake, or both had to be generated to trigger slides on such a low failure plane angle. The shape of the failure plane, the fact that the surface is almost clear of any debris, and the mobility analysis, all support the argument that the slides took place nearly simultaneously. Potential causes for the generation of high pore pressures could be seepage forces from coastal aquifers, delta construction and related pore pressure generation due to the local sediment loading, gas hydrates, and earthquakes. This slide, and its origin, is a spectacular example of the potential threat that submarine mass movements can pose to the US Atlantic coast and underline the need to further assess the potential for the generation of such large slides, like the Grand Banks 1927 landslide of similar volume. ?? 2008 Elsevier B.V.

    The utilization of microsystems technology (MST) in medical applications is instrumental in opening up new market segments, in the creation of novel, more effective diagnosis and therapy options in medicine, as well as in the further development of MST. However, the players in the healthcare industry are faced with technical and non-technical difficulties. The present study analyzes this emerging field from the viewpoint of medicine, market, and MST. It identifies applications of medical devices with microsystems components and analyzes their potentials in great detail. Thus, especially the creation of new market segments is expected from a broad use of MST in medicine. Furthermore, problems and conditions during the entry of microsystems into medical products are illuminated, in particular considering the specific market features of the healthcare industry. The high expenditure necessary for establishing this technology in healthcare industry is the most significant obstacle, since this market is dominated by small and medium-sized enterprises (SMEs). But there are non-technical difficulties as well. This article presents selected results of the study, which was carried out in the scope of the EU project netMED (virtual institute on micromechatronics for biomedical industry).

    Background We evaluated the prevalence of high blood pressure and the level of awareness, treatment, and control of hypertension in a Serbian population. Methods A cross-sectional study of an adult population was carried out across Serbia in 2006. The study involved 14 204 adults aged 20 years or older. Interviews and measurements of blood pressure were performed at participants’ homes. Results Overall, 47% of the Serbian adult population had hypertension: 25.3% had stage 1 hypertension and 18.1% had stage 2 hypertension. Only 58.0% of the hypertensive population were aware that they had the disease, and 60.4% were receiving medical treatment. Among those receiving medical treatment, only 20.9% had a blood pressure within the normal range. One in 10 participants with hypertension were not treated because, among other reasons, they thought treatment was unnecessary (55.3%) or they lacked money for medication (19.3%). Conclusions The prevalence of undiagnosed and untreated hypertension is high in the adult population of Serbia. Further action is required to hasten detection and treatment of high blood pressure. Attention should be directed toward educational programs that improve knowledge, attitudes, and awareness of hypertension among adults. PMID:22374365

    This monograph presents a novel method of sliding mode control for switch-regulated nonlinear systems. The Delta Sigma modulation approach allows one to implement a continuous control scheme using one or multiple, independent switches, thus effectively merging the available linear and nonlinear controller design techniques with sliding mode control.   Sliding Mode Control: The Delta-Sigma Modulation Approach, combines rigorous mathematical derivation of the unique features of Sliding Mode Control and Delta-Sigma modulation with numerous illustrative examples from diverse areas of engineering. In addition, engineering case studies demonstrate the applicability of the technique and the ease with which one can implement the exposed results. This book will appeal to researchers in control engineering and can be used as graduate-level textbook for a first course on sliding mode control.

    What are the faintest distant galaxies we can see with the Hubble Space Telescope ( HST ) now, before the launch of the James Webb Space Telescope ? This is the challenge taken up by the Frontier Fields, a Director’s discretionary time campaign with HST and the Spitzer Space Telescope to see deeper into the universe than ever before. The Frontier Fields combines the power of HST and Spitzer with the natural gravitational telescopes of massive high-magnification clusters of galaxies to produce the deepest observations of clusters and their lensed galaxies ever obtained. Six clusters—Abell 2744, MACSJ0416.1-2403, MACSJ0717.5+3745, MACSJ1149.5+2223, Abell S1063, and Abell 370—have been targeted by the HST ACS/WFC and WFC3/IR cameras with coordinated parallel fields for over 840 HST orbits. The parallel fields are the second-deepest observations thus far by HST with 5 σ point-source depths of ∼29th ABmag. Galaxies behind the clusters experience typical magnification factors of a few, with small regions magnified by factors of 10–100. Therefore, the Frontier Field cluster HST images achieve intrinsic depths of ∼30–33 mag over very small volumes. Spitzer has obtained over 1000 hr of Director’s discretionary imaging of the Frontier Field cluster and parallels in IRAC 3.6 and 4.5 μ m bands to 5 σ point-source depths of ∼26.5, 26.0 ABmag. We demonstrate the exceptional sensitivity of the HST Frontier Field images to faint high-redshift galaxies, and review the initial results related to the primary science goals.

Spitzer has obtained over 1000 hr of Director’s discretionary imaging of the Frontier Field cluster and parallels in IRAC 3.6 and 4.5 μm bands to 5σ point-source depths of ˜26.5, 26.0 ABmag. We demonstrate the exceptional sensitivity of the HST Frontier Field images to faint high-redshift galaxies, and review the initial results related to the primary science goals.

    2017-01-01

    Full Text Available Background: Our institution's pathology unknown conferences provide educational cases for our residents. However, the cases have not been previously available digitally, have not been collated for postconference review, and were not accessible to a wider audience. Our objective was to create an inexpensive whole slide image (WSI education suite to address these limitations and improve the education of pathology trainees. Materials and Methods: We surveyed residents regarding their preference between four unique WSI systems. We then scanned weekly unknown conference cases and study set cases and uploaded them to our custom built WSI viewer located at RecutClub.com. We measured site utilization and conference participation. Results: Residents preferred our OpenLayers WSI implementation to Ventana Virtuoso, Google Maps API, and OpenSlide. Over 16 months, we uploaded 1366 cases from 77 conferences and ten study sets, occupying 793.5 GB of cloud storage. Based on resident evaluations, the interface was easy to use and demonstrated minimal latency. Residents are able to review cases from home and from their mobile devices. Worldwide, 955 unique IP addresses from 52 countries have viewed cases in our site. Conclusions: We implemented a low-cost, publicly available repository of WSI slides for resident education. Our trainees are very satisfied with the freedom to preview either the glass slides or WSI and review the WSI postconference. Both local users and worldwide users actively and repeatedly view cases in our study set.

    Rudi Uswarman

    2014-07-01

    Full Text Available This paper presents global sliding mode control and conventional sliding mode control for stabilization position of a levitation object. Sliding mode control will be robusting when in sliding mode condition. However, it is not necessarily robust at attaining phase. In the global sliding mode control, the attaining motion phase was eliminated, so that the robustness of the controller can be improved. However, the value of the parameter uncertainties needs to be limited. Besides that, the common problem in sliding mode control is high chattering phenomenon. If the chattering is too large, it can make the system unstable due the limited ability of electronics component. The strategy to overcome the chattering phenomenon is needed. Based on simulation and experimental results, the global sliding mode control has better performance than conventional sliding mode control.

    2011-08-01

    This report presents summary results of the 2010 ITS Deployment Tracking survey, the most recent survey conducted by the ITS Deployment Tracking Project. The U.S. Department of Transportation and its member agencies, including the Research and Innovative Technology Administration, have pursued a research and development agenda, the Intelligent Transportation System (ITS) Program, designed to integrate the latest in information technologies to improve the safety, mobility, and reliability of surface transportation modes. Within metropolitan areas, implementation of these advanced technologies has been accomplished by a variety of state and local transportation and emergency management agencies as well as the private sector. In order to measure the rate of ITS deployment within the nation s largest metropolitan areas, the ITS Deployment Tracking Project has conducted a nationwide survey of state and local transportation and emergency management agencies nearly every year since 1997. The results presented in this report are intended to be a summary of the entire database from the 2010 survey. Access to the complete survey results and previous national surveys are available on-line at http://www.itsdeployment.its.dot.gov. The website also provides access to survey results in the form of downloadable reports, including a survey summary for each survey type and fact sheets. Nearly 1,600 surveys were distributed to state and local transportation agencies in 2010. A total of seven (7) survey types were distributed including: Freeway Management, Arterial Management, Transit Management, Transportation Management Center (TMC), Electronic Toll Collection (ETC), Public Safety Law Enforcement, and Public Safety Fire/Rescue. Among other things, the data collection results indicate that ITS has moved from being experimental to mainstream and interest in continuing investments in ITS continues to be very strong. When asked about future deployment plans, one-third to three

    Zhang, Yanhong

    2017-07-01

    A new sliding mode variable structure control algorithm suitable for active magnetic bearing is proposed, which is widely used for nonlinear control system. The model and controller is designed, simulation and experimental parts are also made, according to the switching function and the sliding mode control law. The current of electromagnet is adjusted to realize stable levitation of the rotor. The experimental result shows that the sliding mode variable structure controller is an effective way for magnetic bearing control, and the active magnetic bearing system is a highly nonlinear and advanced control method that can reduce the setting time and the cost.

    The system of Pb-211 robot waist is a nonlinear hydraulic servo control system. It is very difficult to achieve speedy response without overshoot by the PID control algorithm for the system control. To improve the performance of the system, a new controller is designed with a fuzzy sliding-mode control algorithm, which makes use of the merits both the fuzzy control and the sliding-mode control algorithm. The simulation results show that the new controller is effective, which can achieve high speediness and steady accuracy without overshoot. The fuzzy sliding-mode control has obvious advantage compared the traditional PID algorithm, and it has strong robust too.

  17. Color standardization and optimization in Whole Slide Imaging

    Directory of Open Access Journals (Sweden)

    Yagi Yukako

    2011-03-01

    Full Text Available Abstract Introduction Standardization and validation of the color displayed by digital slides is an important aspect of digital pathology implementation. While the most common reason for color variation is the variance in the protocols and practices in the histology lab, the color displayed can also be affected by variation in capture parameters (for example, illumination and filters, image processing and display factors in the digital systems themselves. Method We have been developing techniques for color validation and optimization along two paths. The first was based on two standard slides that are scanned and displayed by the imaging system in question. In this approach, one slide is embedded with nine filters with colors selected especially for H&E stained slides (looking like tiny Macbeth color chart; the specific color of the nine filters were determined in our previous study and modified for whole slide imaging (WSI. The other slide is an H&E stained mouse embryo. Both of these slides were scanned and the displayed images were compared to a standard. The second approach was based on our previous multispectral imaging research. Discussion As a first step, the two slide method (above was used to identify inaccurate display of color and its cause, and to understand the importance of accurate color in digital pathology. We have also improved the multispectral-based algorithm for more consistent results in stain standardization. In near future, the results of the two slide and multispectral techniques can be combined and will be widely available. We have been conducting a series of researches and developing projects to improve image quality to establish Image Quality Standardization. This paper discusses one of most important aspects of image quality – color.

  18. Single molecule study of a processivity clamp sliding on DNA

    2007-07-05

    Using solution based single molecule spectroscopy, we study the motion of the polIII {beta}-subunit DNA sliding clamp ('{beta}-clamp') on DNA. Present in all cellular (and some viral) forms of life, DNA sliding clamps attach to polymerases and allow rapid, processive replication of DNA. In the absence of other proteins, the DNA sliding clamps are thought to 'freely slide' along the DNA; however, the abundance of positively charged residues along the inner surface may create favorable electrostatic contact with the highly negatively charged DNA. We have performed single-molecule measurements on a fluorescently labeled {beta}-clamp loaded onto freely diffusing plasmids annealed with fluorescently labeled primers of up to 90 bases. We find that the diffusion constant for 1D diffusion of the {beta}-clamp on DNA satisfies D {le} 10{sup -14} cm{sup 2}/s, much slower than the frictionless limit of D = 10{sup -10} cm{sup 2}/s. We find that the {beta} clamp remains at the 3-foot end in the presence of E. coli single-stranded binding protein (SSB), which would allow for a sliding clamp to wait for binding of the DNA polymerase. Replacement of SSB with Human RP-A eliminates this interaction; free movement of sliding clamp and poor binding of clamp loader to the junction allows sliding clamp to accumulate on DNA. This result implies that the clamp not only acts as a tether, but also a placeholder.

    High-resolution pathology images provide rich information about the morphological and functional characteristics of biological systems, and are transforming the field of pathology into a new era. To facilitate the use of digital pathology imaging for biomedical research and clinical diagnosis, it is essential to manage and query both whole slide images (WSI) and analytical results generated from images, such as annotations made by humans and computed features and classifications made by computer algorithms. There are unique requirements on modeling, managing and querying whole slide images, including compatibility with standards, scalability, support of image queries at multiple granularities, and support of integrated queries between images and derived results from the images. In this paper, we present our work on developing the Pathology Image Database System (PIDB), which is a standard oriented image database to support retrieval of images, tiles, regions and analytical results, image visualization and experiment management through a unified interface and architecture. The system is deployed for managing and querying whole slide images for In Silico brain tumor studies at Emory University. PIDB is generic and open source, and can be easily used to support other biomedical research projects. It has the potential to be integrated into a Picture Archiving and Communications System (PACS) with powerful query capabilities to support pathology imaging.

  8. Terrain analysis of the racetrack basin and the sliding rocks of Death Valley

    2000-01-01

    The Racetrack Playa's unusual surface features known as sliding rocks have been the subject of an ongoing debate and several mapping projects for half a century, although the causative mechanism remains unresolved. Clasts ranging in volume from large pebbles to medium boulders have, unwitnessed, maneuvered around the nearly flat dry lake over considerable distances. The controversy has persisted partly because eyewitness accounts of the phenomenon continue to be lacking, and the earlier mapping missions were limited in method and geographic range. In July 1996, we generated the first complete map of all observed sliding rock trails by submeter differential Global Positioning System (DGPS) mapping technology. The resulting map shows 162 sliding rocks and associated trails to an accuracy of approximately 30 cm. Although anemometer data are not available in the Racetrack wilderness, wind is clearly a catalyst for sliding rock activity; an inferred wind rose was constructed from DGPS trail segment data. When the entire trail network is examined in plan, some patterns emerge, although other (perhaps expected relations) remain elusive: terrain analysis of the surrounding topography demonstrates that the length and morphology of trails are more closely related to where rocks rested at the onset of motion than to any physical attribute of the rocks themselves. Follow-up surveys in May 1998, May 1999, August 1999, and November 1999 revealed little modification of the July, 1996 sliding rock configuration. Only four rocks were repositioned during the El Nino winter of 1997-1998, suggesting that activity may not be restricted to winter storms. (C) 2000 Elsevier Science B.V. All rights reserved.

  9. Comprehensive investigation of submarine slide zones and mass movements at the northern continental slope of South China Sea

    Chen, Hongjun; Liang, Jin; Gong, Yuehua

    2018-02-01

    Multi-beam bathymetry and seismic sequence surveys in the northern slope of the South China Sea reveal detailed geomorphology and seismic stratigraphy characteristics of canyons, gullies, and mass movements. Modern canyons and gullies are roughly elongated NNW-SSW with U-shaped cross sections at water depths of 400-1000 m. Mass movements include slide complexes, slide scars, and debris/turbidity flows. Slide complexes and slide scars are oriented in the NE-SW direction and cover an area of about 1790 and 926 km2, respectively. The debris/turbidity flows developed along the lower slope. A detailed facies analysis suggests that four seismic facies exist, and the late Cenozoic stratigraphy above the acoustic basement can be roughly subdivided into three sequences separated by regional unconformities in the study area. The occurrence of gas hydrates is marked by seismic velocity anomalies, bottom-simulating reflectors, gas chimneys, and pockmarks in the study area. Seismic observations suggest that modern canyons and mass movements formed around the transition between the last glacial period and the current interglacial period. The possible existence and dissociation of gas hydrates and the regional tectonic setting may trigger instability and mass movements on the seafloor. Canyons may be the final result of gas hydrate dissociation. Our study aims to contribute new information that is applicable to engineering construction required for deep-water petroleum exploration and gas hydrate surveys along any marginal sea.

  10. Interpreting household survey data intended to measure insecticide-treated bednet coverage: results from two surveys in Eritrea

    Directory of Open Access Journals (Sweden)

    Yukich Josh

    2006-05-01

    Full Text Available Abstract Background As efforts are currently underway to roll-out insecticide-treated bednets (ITNs to populations within malarious areas in Africa, there is an unprecedented need for data to measure the effectiveness of such programmes in terms of population coverage. This paper examines methodological issues to using household surveys to measure core Roll Back Malaria coverage indicators of ITN possession and use. Methods ITN coverage estimates within Anseba and Gash Barka Provinces from the 2002 Eritrean Demographic and Health Survey, implemented just prior to a large-scale ITN distribution programme, are compared to estimates from the same area from a sub-national Bednet Survey implemented 18 months later in 2003 after the roll-out of the ITN programme. Results Measures of bednet possession were dramatically higher in 2003 compared to 2002. In 2003, 82.2% (95% confidence interval (CI 77.4–87.0 of households in Anseba and Gash Barka possessed at least one ITN. RBM coverage indicators for ITN use were also dramatically higher in 2003 as compared to 2002, with 76.1% (95% CI 69.9–82.2 of children under five years old and 52.4% (95% CI 38.2–66.6 of pregnant women sleeping under ITNs. The ITN distribution programme resulted in a gross increase in ITN use among children and pregnant women of 68.3% and 48% respectively. Conclusion Eritrea has exceeded the Abuja targets of 60% coverage for ITN household possession and use among children under five years old within two malarious provinces. Results point to several important potential sources of bias that must be considered when interpreting data for ITN coverage over time, including: disparate survey universes and target populations that may include non-malarious areas; poor date recall of bednet procurement and treatment; and differences in timing of surveys with respect to malaria season.

    An adaptive sliding mode control (ASMC) technique is introduced in this paper for a chaotic dynamical system (Genesio-Tesi system). Using the sliding mode control technique, a sliding surface is determined and the control law is established. An adaptive sliding mode control law is derived to make the states of the Genesio-Tesi system asymptotically track and regulate the desired state. The designed control scheme can control the uncertain chaotic behaviors to a desired state without oscillating very fast and guarantee the property of asymptotical stability. An illustrative simulation result is given to demonstrate the effectiveness of the proposed adaptive sliding mode control design.

    Douma, Lauren G; Yu, Kevin K; England, Jennifer K; Levitus, Marcia; Bloom, Linda B

    2017-09-29

    Clamp loaders load ring-shaped sliding clamps onto DNA where the clamps serve as processivity factors for DNA polymerases. In the first stage of clamp loading, clamp loaders bind and stabilize clamps in an open conformation, and in the second stage, clamp loaders place the open clamps around DNA so that the clamps encircle DNA. Here, the mechanism of the initial clamp opening stage is investigated. Mutations were introduced into the Escherichia coli β-sliding clamp that destabilize the dimer interface to determine whether the formation of an open clamp loader-clamp complex is dependent on spontaneous clamp opening events. In other work, we showed that mutation of a positively charged Arg residue at the β-dimer interface and high NaCl concentrations destabilize the clamp, but neither facilitates the formation of an open clamp loader-clamp complex in experiments presented here. Clamp opening reactions could be fit to a minimal three-step 'bind-open-lock' model in which the clamp loader binds a closed clamp, the clamp opens, and subsequent conformational rearrangements 'lock' the clamp loader-clamp complex in a stable open conformation. Our results support a model in which the E. coli clamp loader actively opens the β-sliding clamp. © The Author(s) 2017. Published by Oxford University Press on behalf of Nucleic Acids Research.

  18. Universal Aging Mechanism for Static and Sliding Friction of Metallic Nanoparticles.

    Science.gov (United States)

    Feldmann, Michael; Dietzel, Dirk; Tekiel, Antoni; Topple, Jessica; Grütter, Peter; Schirmeisen, André

    2016-07-08

    The term "contact aging" refers to the temporal evolution of the interface between a slider and a substrate usually resulting in increasing friction with time. Current phenomenological models for multiasperity contacts anticipate that such aging is not only the driving force behind the transition from static to sliding friction, but at the same time influences the general dynamics of the sliding friction process. To correlate static and sliding friction on the nanoscale, we show experimental evidence of stick-slip friction for nanoparticles sliding on graphite over a wide dynamic range. We can assign defined periods of aging to the stick phases of the particles, which agree with simulations explicitly including contact aging. Additional slide-hold-slide experiments for the same system allow linking the sliding friction results to static friction measurements, where both friction mechanisms can be universally described by a common aging formalism.

    The National Wildlife Refuge System (Refuge System), established in 1903 and managed by the U.S. Fish and Wildlife Service (Service), is the leading network of protected lands and waters in the world dedicated to the conservation of fish, wildlife and their habitats. There are 556 national wildlife refuges and 38 wetland management districts nationwide, encompassing more than 150 million acres. The Refuge System attracts more than 45 million visitors annually, including 25 million people per year to observe and photograph wildlife, over 9 million to hunt and fish, and more than 10 million to participate in educational and interpretation programs. Understanding visitors and characterizing their experiences on national wildlife refuges are critical elements of managing these lands and meeting the goals of the Refuge System. The Service collaborated with the U.S. Geological Survey to conduct a national survey of visitors regarding their experiences on national wildlife refuges. The survey was conducted to better understand visitor needs and experiences and to design programs and facilities that respond to those needs. The survey results will inform Service performance planning, budget, and communications goals. Results will also inform Comprehensive Conservation Plan (CCPs), Visitor Services, and Transportation Planning processes. This data series consists of 53 separate data files. Each file describes the results of the survey for an individual refuge and contains the following information: * Introduction: An overview of the Refuge System and the goals of the national surveying effort. * Methods: The procedures for the national surveying effort, including selecting refuges, developing the survey instrument, contacting visitors, and guidance for interpreting the results. * Refuge Description: A brief description of the refuge location, acreage, purpose, recreational activities, and visitation statistics, including a map (where available) and refuge website link

  2. Evolutions of friction properties and acoustic emission source parameters associated with large sliding

    Yabe, Y.; Tsuda, H.; Iida, T.

    2015-12-01

    It was demonstrated by Yabe (2002) that friction properties and AE (acoustic emission) activities evolve with accumulation of sliding. However, large sliding distances of ~65 mm in his experiments were achieved by recurring ~10 mm sliding on the same fault. The evolution of friction coefficient was discontinuous, when rock samples were reset. Further, normal stress was not kept constant. To overcome these problems and to reexamine the evolutions of friction properties and AE activities with continuous large sliding under a constant normal stress, we developed a rotary shear apparatus. The evolutions of friction and AE up to ~80 mm sliding under a normal stress of 5 MPa were investigated. Rate dependence of friction was the velocity strengthening (a-b>0 in rate and state friction law) at the beginning. The value of a-b gradually decreased with sliding to negative (velocity weakening). Then, it took a constant negative value, when the sliding reached a critical distance. The m-value of Ishimoto-Iida's relation of AE activity increased with sliding at the beginning and converged to a constant value at the critical sliding distance. The m-value showed a negative rate dependence at the beginning, but became neutral after sliding of the critical distance. The sliding distances required to converge the a-b value, the m-value and the rate dependence of the m-value are almost identical to one another. These results are the same as those by Yabe (2002), suggesting the intermission of sliding little affected the evolutions. We, then, examined evolutions of AE source parameters such as source radii and stress drops. The average source radius was constant over the whole sliding distance, while the average stress drop decreased at the beginning of sliding, and converged to a constant value. The sliding distance required to the conversion was the same as that for the above mentioned evolutions of friction property or AE activity.

    According to the characteristics of the flow field of the sliding bearing, the CFD numerical calculation model of the sliding bearing was established. The CFD method was used to simulate the flow field of the sliding bearing, and the pressure distribution of the sliding bearing flow field was obtained. Based on this, the stiffness and the damping coefficient of the dynamic characteristics were obtained by the dynamic grid technique. The influence of the rotational speed on the dynamic characteristic coefficient was further studied. The results show that the difference between the stiffness coefficient and the damping coefficient is less than 5%, and the accuracy of the model is verified. The absolute value of the oil film stiffness increases non-linearly with the increase of the rotational speed, and the influence of the rotational speed on the damping coefficient is small.

    Full Text Available Sliding mode controllers have succeeded in many control problems that the conventional control theories have difficulties to deal with; however it is practically impossible to achieve high-speed switching control. Therefore, in this paper an adaptive fuzzy backstepping sliding mode control scheme is derived for mismatched uncertain systems. Firstly fuzzy sliding mode controller is designed using backstepping method based on the Lyapunov function approach, which is capable of handling mismatched problem. Then fuzzy sliding mode controller is designed using T-S fuzzy model method, it can improve the performance of the control systems and their robustness. Finally this method of control is applied to nonlinear system as a case study; simulation results are also provided the performance of the proposed controller.

    Full Text Available Abstract Background Health-related data at local level could be provided by supplementing national health surveys with local boosts. Self-completion surveys are less costly than interviews, enabling larger samples to be achieved for a given cost. However, even when the same questions are asked with the same wording, responses to survey questions may vary by mode of data collection. These measurement differences need to be investigated further. Methods The Health Survey for England in London ('Core' and a London Boost survey ('Boost' used identical sampling strategies but different modes of data collection. Some data were collected by face-to-face interview in the Core and by self-completion in the Boost; other data were collected by self-completion questionnaire in both, but the context differed. Results were compared by mode of data collection using two approaches. The first examined differences in results that remained after adjusting the samples for differences in response. The second compared results after using propensity score matching to reduce any differences in sample composition. Results There were no significant differences between the two samples for prevalence of some variables including long-term illness, limiting long-term illness, current rates of smoking, whether participants drank alcohol, and how often they usually drank. However, there were a number of differences, some quite large, between some key measures including: general health, GHQ12 score, portions of fruit and vegetables consumed, levels of physical activity, and, to a lesser extent, smoking consumption, the number of alcohol units reported consumed on the heaviest day of drinking in the last week and perceived social support (among women only. Conclusion Survey mode and context can both affect the responses given. The effect is largest for complex question modules but was also seen for identical self-completion questions.

    Full Text Available Background: Whole slide imaging (WSI is widely used for education and research, but is increasingly being used to streamline clinical workflow. We present our experience with regard to satisfaction and time utilization using oil immersion WSI for presentation of blood/marrow aspirate smears, core biopsies, and tissue sections in hematology/oncology tumor board/treatment planning conferences (TPC. Methods: Lymph nodes and bone marrow core biopsies were scanned at ×20 magnification and blood/marrow smears at 83X under oil immersion and uploaded to an online library with areas of interest to be displayed annotated digitally via web browser. Pathologist time required to prepare slides for scanning was compared to that required to prepare for microscope projection (MP. Time required to present cases during TPC was also compared. A 10-point evaluation survey was used to assess clinician satisfaction with each presentation method. Results: There was no significant difference in hematopathologist preparation time between WSI and MP. However, presentation time was significantly less for WSI compared to MP as selection and annotation of slides was done prior to TPC with WSI, enabling more efficient use of TPC presentation time. Survey results showed a significant increase in satisfaction by clinical attendees with regard to image quality, efficiency of presentation of pertinent findings, aid in clinical decision-making, and overall satisfaction regarding pathology presentation. A majority of respondents also noted decreased motion sickness with WSI. Conclusions: Whole slide imaging, particularly with the ability to use oil scanning, provides higher quality images compared to MP and significantly increases clinician satisfaction. WSI streamlines preparation for TPC by permitting prior slide selection, resulting in greater efficiency during TPC presentation.

    In artisanal small-scale gold mining, mercury is used for gold-extraction, putting miners and nearby residents at risk of chronic metallic mercury vapor intoxication (CMMVI). Burden of disease (BoD) analyses allow the estimation of the public health relevance of CMMVI, but until now there have been no specific CMMVI disability weights (DWs). The objective is to derive DWs for moderate and severe CMMVI. Disease-specific and generic health state descriptions of 18 diseases were used in a pairwise comparison survey. Mercury and BoD experts were invited to participate in an online survey. Data were analyzed using probit regression. Local regression was used to make the DWs comparable to the Global Burden of Disease (GBD) study. Alternative survey (visual analogue scale) and data analyses approaches (linear interpolation) were evaluated in scenario analyses. A total of 105 participants completed the questionnaire. DWs for moderate and severe CMMVI were 0.368 (0.261-0.484) and 0.588 (0.193-0.907), respectively. Scenario analyses resulted in higher mean values. The results are limited by the sample size, group of interviewees, questionnaire extent, and lack of generally accepted health state descriptions. DWs were derived to improve the data basis of mercury-related BoD estimates, providing useful information for policy-making. Integration of the results into the GBD DWs enhances comparability.

    A large proportion of health promotion campaign evaluation research has historically been conducted via telephone surveys. However, there are concerns about the continued viability of this form of surveying in providing relevant and representative data. Online surveys are an increasingly popular alternative, and as such there is a need to assess the comparability between data collected using the two different methods to determine the implications for longitudinal comparisons. The present study compared these survey modes in the context of health promotion evaluation research. Data were collected via computer-assisted telephone interviewing and an online panel. In total, 688 and 606 respondents aged between 14 and 45 years completed the online and telephone surveys, respectively. Online respondents demonstrated higher awareness of the advertisement, rated the advertisement as more personally relevant and had better behavioural outcomes compared with the telephone respondents. The results indicate significant differences between the telephone and online surveys on most measures used to assess the effectiveness of a health promotion advertising campaign. Health promotion practitioners could consider the combination of both methods to overcome the deterioration in telephone survey response rates and the likely differences in respondent outcomes.

    A prospective study, including 112 patients, designed to estimate the sensitivity and specificity of slide-touch and pleural lavage cytology for diagnosis of pleural micrometastases in operable non-small cell lung cancer (NSCLC). Histopathologically, excised tumors showed P0 in 22 patients (19%), P1 in 44 patients (39%), P2 in 32 patients (29%), P3 in 14 patients (13%). Cytological examination of the three slide-touch prints from visceral pleura overlying the tumor (slide 1), parietal pleura facing tumor (slide 2), parietal pleura in paravertebral gutter (slide 3) resulted in: slide 1: positive in 60% (66/112) [this included p0 (2 out of 22), p1 (22 out of 44), p2 (32 out of 32) and p3 (10 out of 14)], slide 2: positive in 13% (14/112); all of them had P3, and slide 3 positive in 8% (9/112). Total positive slides 62% (70/112). Pleural lavage: positive in 19% (22/112), all of them were detected with slide 1 and/or slide 2. During follow-up, patients with negative slides had no local or distant metastases (truly negative), six recurrences among those with positive slide 1, including four with positive lavage. Thus, slide touch print is more sensitive than lavage cytology, both of prognostic significance. Slide 1 is a highly sensitive detector of visceral pleural micrometastases; slide 2 is a more sensitive detector of parietal pleural invasion; slide 3 is the least.

    The inherent nature of the Korean National Health and Nutrition Examination Survey (KNHANES) design requires special analysis by incorporating sample weights, stratification, and clustering not used in ordinary statistical procedures. This study investigated the proportion of research papers that have used an appropriate statistical methodology out of the research papers analyzing the KNHANES cited in the PubMed online system from 2007 to 2012. We also compared differences in mean and regression estimates between the ordinary statistical data analyses without sampling weight and design-based data analyses using the KNHANES 2008 to 2010. Of the 247 research articles cited in PubMed, only 19.8% of all articles used survey design analysis, compared with 80.2% of articles that used ordinary statistical analysis, treating KNHANES data as if it were collected using a simple random sampling method. Means and standard errors differed between the ordinary statistical data analyses and design-based analyses, and the standard errors in the design-based analyses tended to be larger than those in the ordinary statistical data analyses. Ignoring complex survey design can result in biased estimates and overstated significance levels. Sample weights, stratification, and clustering of the design must be incorporated into analyses to ensure the development of appropriate estimates and standard errors of these estimates.

    2016-05-01

    Full Text Available This study asked two broad questions: (1 what is the prevalence of teen pregnancy in contemporary Vietnam; and (2 what selected social, family, and individual factors are associated with teen pregnancy in Vietnam? The study utilized Vietnam Survey Assessment of Vietnamese Youth surveys conducted in 2003 and 2008 to answer the two research questions within the context of fast political, economic, and social change in Vietnam in the last two decades. Results of this study show that the prevalence of pregnancy among Vietnamese teenagers in the surveys was stable at 4%, or 40 pregnancies per 1000 adolescent girls aged 14 to 19. Age, experience of domestic violence, and early sexual debut were positively correlated with higher odds of teenage pregnancy for both survey cohorts; however, being an ethnic minority, educational attainment, sexual education at school, Internet use, and depressive symptoms were significantly related to teenage pregnancy only in the 2008 cohort.

    2011-08-01

    Full Text Available This paper reports a comparison of South African household inflation expectations and inflation credibility surveys undertaken in 2006 and 2008. It tests for possible feed-through between inflation credibility and inflation expectations. It supplements earlier research that focused only on the 2006 survey results. The comparison shows that inflation expectations differed between different income groups in both 2006 and 2008. Inflation credibility differed between male and female respondents, but this difference did not feed through to inflation expectations. More periodic survey data will be required for developing final conclusions on the possibility of feed-through effects. To this end the structure of credibility surveys should be reconsidered, as a large percentage of respondents indicated that they ‘don’t know’ whether the historic rate of inflation is an accurate indication of price increases.

    We present results from the first comprehensive survey program dedicated to probing transiting exoplanet atmospheres using transmission spectroscopy with a multi-object spectrograph (MOS). Our four-years survey focussed on ten close-in giant planets for which the wavelength dependent transit depths in the visible were measured with Gemini/GMOS. We present the complete analysis of all the targets observed (50 transits, 300 hours), and the challenges to overcome to achieve the best spectrophotometric precision (200-500 ppm / 10 nm). We also present the main results and conclusions from this survey. We show that the precision achieved by this survey permits to distinguish hazy atmospheres from cloud-free ones. We discuss the challenges faced by such an experiment, and the lessons learnt for future MOS survey. We lay out the challenges facing future ground based MOS transit surveys aiming for the atmospheric characterization of habitable worlds, and utilizing the next generation of multi-object spectrographs mounted on extremely large ground based telescopes (ELT, TMT).

    In 2014, the Association of Directors of Radiation Oncology Programs (ADROP) conducted an in-depth survey of program directors along several axes. We report the results of this survey and compare the major findings with those of the 2007 ADROP survey. The survey was written and approved by ADROP leadership in 2012, announced online through broadcasts throughout 2013 and early 2014, and closed in mid-2014. The results based on question groups related to (1) hours spent in activities, (2) budget and nonprogram resources, (3) physics/biology didactics, (4) mock exams/didactics/research, (5) electives, (6) students, and (7) resources/challenges were tabulated. Descriptive comparisons with the 2007 survey were performed. There was 26% participation (23/88 programs). Major areas of time commitment were faculty and site organization, maintenance, and corrections (70 hours/year) and didactics/conferences and rounds (200 hours/year). The median program director protected time was 23% (range 0%-50%). All responding programs (100%) had biology and physics courses and assigned directors, but only approximately 20% of respondents had a threshold grade in these courses for graduation. Major resources desired were templates of goals/objectives by disease site, competency evaluations by level, journal club repository, and software for contouring, oral examination preparation, grant writing, publication writing, oral presentation, and effective teaching. Major activity challenges were Accreditation Council for Graduate Medical Education external review and time commitment. Overall, the 2014 results are similar to those of the 2007 survey. The average time commitment remains considerably higher than the 10% minimum required in the current ACGME program requirements. The survey results may guide ADROP membership in centralizing some of the identified resources needed. Copyright © 2015 American Society for Radiation Oncology. Published by Elsevier Inc.

  6. The Microseismicity of Glacier Sliding

    Science.gov (United States)

    Walter, Fabian; Röösli, Claudia; Kissling, Edi

    2017-04-01

    Our understanding of glacier and ice sheet basal motion remains incomplete. The past decades have witnessed a shift away from initially proposed hard bed theories towards soft, till-laden beds, which deform and thus participate in basal motion. The theoretical treatment of deformable beds is subject to debate, yet our capability to predict ice sheet flow and ultimately sea level rise is contingent upon correct parameterization of basal motion (Ritz et al., 2015). Both hard and soft bed theories neglect frictional sliding across distinct basal fault planes and elastic deformation in response to sudden dislocation. Over recent years, this view has been repeatedly challenged as more and more studies report seismogenic faulting associated with basal sliding. For instance, large parts of the Whillans Ice Stream at Antarctica's Siple Coast move nearly exclusively during sudden sliding episodes (Wiens et al., 2008). This "stick-slip motion" is difficult to explain with traditional glacier sliding theories but more analogous to earthquake dislocation on tectonic faults. Although the Whillans Ice Stream motion may be an extreme example, there exists evidence for much smaller microseismic stick-slip events beneath the Greenland Ice Sheet and non-polar glaciers (Podolskiy and Walter, 2016). This raises the question how relevant and widespread the stick-slip phenomenon is and if it is necessary to include it into ice sheet models. Here we discuss recent seismic deployments, which focused on detection of stick-slip events beneath the Greenland Ice Sheet and European Alpine Glaciers. For all deployments, a considerable challenge lies in detection of stick-slip seismograms in the presence of a dominant background seismicity associated with surface crevassing. Nevertheless, automatic search algorithms and waveform characteristics provide important insights into temporal variation of stick-slip activity as well as information about fault plane geometry and co-seismic sliding

Simulation results compare two methods for obtaining of position derivatives needed for SMC algorithm. The first method exploits a filtering observer and second one uses numerical derivations and first order filters.

  9. The accuracy of dynamic predictive autofocusing for whole slide imaging

    Directory of Open Access Journals (Sweden)

    Richard R McKay

    2011-01-01

    Full Text Available Context: Whole slide imaging (WSI for digital pathology involves the rapid automated acquisition of multiple high-power fields from a microscope slide containing a tissue specimen. Capturing each field in the correct focal plane is essential to create high-quality digital images. Others have described a novel focusing method which reduces the number of focal planes required to generate accurate focus. However, this method was not applied dynamically in an automated WSI system under continuous motion. Aims: This report measures the accuracy of this method when applied in a rapid continuous scan mode using a dual sensor WSI system with interleaved acquisition of images. Methods: We acquired over 400 tiles in a "stop and go" scan mode, surveying the entire z depth in each tile and used this as ground truth. We compared this ground truth focal height to the focal height determined using a rapid 3-point focus algorithm applied dynamically in a continuous scanning mode. Results: Our data showed the average focal height error of 0.30 (±0.27 μm compared to ground truth, which is well within the system′s depth of field. On a tile by tile assessment, approximately 95% of the tiles were within the system′s depth of field. Further, this method was six times faster than acquiring tiles compared to the same method in a non-continuous scan mode. Conclusions: The data indicates that the method employed can yield a significant improvement in scan speed while maintaining highly accurate autofocusing.

    To compare the clinical and second-look arthroscopic outcomes in patients undergoing arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy for varus ankle osteoarthritis, with or without adipose-derived mesenchymal stem cell (MSC) injection. In this retrospective comparative study, 49 patients with varus ankle osteoarthritis underwent second-look arthroscopy after arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy between January 2010 and November 2012; 23 ankles underwent marrow stimulation alone (group 1), and 26 underwent marrow stimulation with MSC injection (group 2). The decision whether to receive the MSC injection, which was free of charge, was solely up to the patients. Second-look arthroscopies were performed at a mean of 12.5 months and 12.4 months postoperatively in group 1 and group 2, respectively. Clinical outcome measures included a visual analog scale (VAS) score for pain and the American Orthopaedic Foot & Ankle Society (AOFAS) score. The radiologic outcome variable was the talar tilt angle. On second-look arthroscopy, cartilage regeneration was evaluated using the International Cartilage Repair Society (ICRS) grade. The mean VAS score improved significantly from 7.3 ± 0.9 to 3.9 ± 1.2 in group 1 and from 7.4 ± 0.8 to 3.1 ± 1.5 in group 2 at final follow-up (P osteoarthritis who underwent lateral sliding calcaneal osteotomy, significant improvements in VAS and AOFAS scores, as well as better ICRS grades, were achieved at short-term follow-up after marrow stimulation with additional MSC injection compared with after marrow stimulation alone.

    Full Text Available Background: One of the drawbacks of studying pathology in the second year of medical school in a classroom setting is the relatively limited exposure to patient encounters/clinical rotations, making it difficult to understand and fully appreciate the significance of the course material, specifically the molecular and tissue aspects of disease. In this study, we determined if case vignettes incorporating pathologist-clinician encounters with whole slide imaging (WSI and narrated/annotated videos of whole slide (WS scans in addition to clinical data improved student understanding of pathologic disease processes. Materials and Methods: Case vignettes were created for several genitourinary disease processes that utilized clinical data including narratives of pathologist-clinician encounters, WSI, and annotated video tutorials of WS scans (designed to simulate "double-heading". The students were encouraged to view the virtual slide first, with the video tutorials being provided to offer additional assistance. The case vignettes were created to be interactive with a detailed explanation of each correct and incorrect question choice. The cases were made available to all second year medical students via a website and could be viewed only after completing a 10 question pre-test. A post-test could be completed after viewing all cases followed by a brief satisfaction survey. Results: Ninety-six students completed the pre-test with an average score of 7.7/10. Fifty-seven students completed the post-test with an average score of 9.4/10. Thirty-six students completed the satisfaction survey. 94% agreed or strongly agreed that this was a useful exercise and 91% felt that it helped them better understand the topics. Conclusion: The development of interactive case vignettes incorporating simulated pathologist-clinician encounters with WSI and video tutorials of WS scans helps to improve student enthusiasm to learn and grasp pathologic aspects of disease

    Objective In recent years increasing interest in the issue of treatment personalization for type 2 diabetes (T2DM) has emerged. This international web-based survey aimed to evaluate opinions of physicians about tailored therapeutic algorithms developed by the Italian Association of Diabetologists (AMD) and available online, and to get suggestions for future developments. Another aim of this initiative was to assess whether the online advertising and the survey would have increased the global visibility of the AMD algorithms. Research design and methods The web-based survey, which comprised five questions, has been available from the homepage of the web-version of the journal Diabetes Care throughout the month of December 2013, and on the AMD website between December 2013 and September 2014. Participation was totally free and responders were anonymous. Results Overall, 452 physicians (M=58.4%) participated in the survey. Diabetologists accounted for 76.8% of responders. The results of the survey show wide agreement (>90%) by participants on the utility of the algorithms proposed, even if they do not cover all possible needs of patients with T2DM for a personalized therapeutic approach. In the online survey period and in the months after its conclusion, a relevant and durable increase in the number of unique users who visited the websites was registered, compared to the period preceding the survey. Conclusions Patients with T2DM are heterogeneous, and there is interest toward accessible and easy to use personalized therapeutic algorithms. Responders opinions probably reflect the peculiar organization of diabetes care in each country. PMID:26301097

    Landsat satellites have been operating since 1972, providing a continuous global record of the Earth’s land surface. The imagery is currently available at no cost through the U.S. Geological Survey (USGS). Social scientists at the USGS Fort Collins Science Center conducted an extensive survey in early 2012 to explore who uses Landsat imagery, how they use the imagery, and what the value of the imagery is to them. The survey was sent to all users registered with USGS who had accessed Landsat imagery in the year prior to the survey and over 11,000 current Landsat imagery users responded. The results of the survey revealed that respondents from many sectors use Landsat imagery in myriad project locations and scales, as well as application areas. The value of Landsat imagery to these users was demonstrated by the high importance of and dependence on the imagery, the numerous environmental and societal benefits observed from projects using Landsat imagery, the potential negative impacts on users’ work if Landsat imagery was no longer available, and the substantial aggregated annual economic benefit from the imagery. These results represent only the value of Landsat to users registered with USGS; further research would help to determine what the value of the imagery is to a greater segment of the population, such as downstream users of the imagery and imagery-derived products.

    We present new results from the first search for transiting exoplanets undertaken from the High Arctic: the AWCam (Arctic Wide-field Cameras) survey. The survey, which has been operating for 2.5 years, is based at 80 degrees North on Ellesmere Island in the Canadian High Arctic. The small telescopes monitor 70,000 bright stars in a several-hundred square-degree region around Polaris, with milli-magnitude photometric precision, and are capable of discovering giant planets around 10,000 bright, nearby solar-type stars. We present the first longterm monitoring results from the AWCams, including an assessment of the site characteristics and the systems' long-term performance. The High-Arctic site provided excellent survey efficiency, without diurnal windowing and largely uninterrupted by clouds. Useful data was obtained over the entire survey field 71% of the time; the sky was clear 62% of the time. One pristine clear, dark period in winter 2012/13 persisted for 480 hours. In 2012/13 we recorded a period of 480 hours of continuous photometric conditions, attaining 3-4 millimag photometric stability over the entire period. We report the long-term photometric performance of the AWCam systems and detail the discovery of a bright (V=8) low-amplitude eclipsing binary. Finally, we present a concept for an extremely-wide-field arctic survey based on the Evryscope telescope-array design.

    We present the results of the 2015 quality metrics (QUALMET) survey, which was designed to assess the commonalities and variability of selected quality and productivity metrics currently employed by a large sample of academic radiology departments representing all regions in the USA. The survey of key radiology metrics was distributed in March-April of 2015 via personal e-mail to 112 academic radiology departments. There was a 34.8% institutional response rate. We found that most academic departments of radiology commonly utilize metrics of hand hygiene, report turn around time (RTAT), relative value unit (RVU) productivity, patient satisfaction and participation in peer review. RTAT targets were found to vary widely. The implementation of radiology peer review and the variety of ways in which peer review results are used within academic radiology departments, the use of clinical decision support tools and requirements for radiologist participation in Maintenance of Certification also varied. Policies for hand hygiene and critical results communication were very similar across all institutions reporting, and most departments utilized some form of missed case/difficult case conference as part of their quality and safety programme, as well as some form of periodic radiologist performance reviews. Results of the QUALMET survey suggest many similarities in tracking and utilization of the selected quality and productivity metrics included in our survey. Use of quality indicators is not a fully standardized process among academic radiology departments. Advances in knowledge: This article examines the current quality and productivity metrics in academic radiology.

    2014-01-01

    During the past two decades, professional associations, accrediting bodies, and payors have made post-surgical pain treatment a high priority. In light of the disappointing findings in previous surveys, a survey was conducted to assess patient perceptions and characterize patient experiences/levels of satisfaction with post-surgical pain management. Survey included a random sample of US adults who had undergone surgery within 5 years from the survey date. Participants were asked about their concerns before surgery, severity of perioperative pain, pain treatments, perceptions about post-surgical pain and pain medications, and satisfaction with treatments they received. Of the 300 participants, ∼86% experienced pain after surgery; of these, 75% had moderate/extreme pain during the immediate post-surgical period, with 74% still experiencing these levels of pain after discharge. Post-surgical pain was the most prominent pre-surgical patient concern, and nearly half reported they had high/very high anxiety levels about pain before surgery. Approximately 88% received analgesic medications to manage pain; of these, 80% experienced adverse effects and 39% reported moderate/severe pain even after receiving their first dose. Key study limitations include the relatively small population size, potential for recall bias associated with the 14-month average time delay from surgery date to survey date, and the inability to account for influences of type of surgery and intraoperative anesthetic/analgesic use on survey results. Despite heightened awareness and clinical advancements in pain management, there has been little improvement in post-surgical analgesia as measured by this survey of post-surgical patients.

    Allergic rhinitis (AR), a chronic inflammatory disease of the upper airway, is one of the most common chronic diseases in the United States and is estimated to affect up to 60 million people. Pediatric Allergies in America is the largest and most comprehensive survey to date of pediatric patients and parents of patients with allergy, as well as health care providers (HCPs), regarding AR in children and its treatment. The goals of the survey were to determine the prevalence of AR in the US pediatric population and to collect information on what effect the condition has on patients in terms of symptom burden, quality of life, productivity, disease management, and pharmacologic treatment. This national survey screened 35,757 households to identify 500 children with HCP-diagnosed nasal allergies and 504 children without nasal allergies who were between the ages of 4 and 17 years. Parents of young children, as well as children 10 to 17 years of age, were questioned about the condition and its treatment. In parallel, 501 HCPs were interviewed. This survey has captured previously unavailable data on the prevalence of nasal allergies and their most common and most bothersome symptoms, on the effect of nasal allergies on the quality of life of children, and on medication use, including both over-the-counter and prescription medications, and has identified factors affecting satisfaction with treatment. The Pediatric Allergies in America survey also identifies distinct areas for improvement in the management of AR in children. In fact, based on the results of this survey, it appears that HCPs overestimate patients' and parents' satisfaction with disease management and the benefit of medications used for the treatment of nasal allergies in children. Findings from this national survey have identified important challenges to the management of AR, suggesting that its burden on children in the United States has been significantly underestimated.

    2005-01-01

    Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents.

    2017-11-01

    Aims: We present the results of a polarimetric survey of main-belt asteroids at Complejo Astronómico El Leoncito (CASLEO), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry and to estimate the diversity in the polarimetric properties of asteroids that belong to different taxonomic classes. Methods: The data were obtained using the CASPOL polarimeter at the 2.15 m telescope. CASPOL is a polarimeter based on a CCD detector and a Savart plate. The survey began in 1995 and data on a large sample of asteroids were obtained until 2012. A second period began in 2013 using a polarimeter with a more sensitive detector in order to study small asteroids, families, and special taxonomic groups. Results: We present and analyze the unpublished results for 128 asteroids of different taxonomic types, 55 of them observed for the first time. The observational data allowed us to find probable new cases of Barbarian objects but also two D-type objects, (565) Marbachia and (1481) Tubingia, that seem to have phase-polarization curves with a large inversion angle. The data obtained combined with data from the literature enabled us to find phase-polarization curves for 121 objects of different taxonomic types and to study the relations between several polarimetric and physical parameters. Using an approximation for the phase-polarization curve we found the index of refraction of the surface material and the scatter separation distance for all the objects with known polarimetric parameters. We also found that the inversion angle is a function of the index of refraction of the surface, while the phase angle where the minimum of polarization is produced provides information about the distance between scatter particles or, to some extent, the porosity of the surface. Based on observations carried out at the Complejo Astronómico El Leoncito, operated under agreement between the Consejo Nacional de Investigaciones Científicas y Técnicas de la

    2014-12-01

    The purpose of this study was to characterize the climate and culture experienced by lesbian, gay, bisexual, and transgender (LGBT) employees and students at one large academic medical center. An anonymous, online institutional climate survey was used to assess the attitudes and experiences of LGBT employees and students. There were 42 LGBT and 14 non-LGBT survey participants. Results revealed that a surprisingly large percentage of LGBT individuals experienced pressure to remain "closeted" and were harassed despite medical center policies of non-discrimination. Continuing training, inclusive policies and practices, and the development of mechanisms to address LGBT-specific harassment are necessary for improving institutional climate.

    Almutairi, Naif B; Zribi, Mohamed

    2016-01-01

    This paper investigates the design of two sliding mode controllers (SMCs) applied to a tempered glass furnace system. The main objective of the proposed controllers is to regulate the glass plate temperature, the upper-wall temperature and the lower-wall temperature in the furnace to a common desired temperature. The first controller is a conventional sliding mode controller. The key step in the design of this controller is the introduction of a nonlinear transformation that maps the dynamic model of the tempered glass furnace into the generalized controller canonical form; this step facilitates the design of the sliding mode controller. The second controller is based on a state-dependent coefficient (SDC) factorization of the tempered glass furnace dynamic model. Using an SDC factorization, a simplified sliding mode controller is designed. The simulation results indicate that the two proposed control schemes work very well. Moreover, the robustness of the control schemes to changes in the system's parameters as well as to disturbances is investigated. In addition, a comparison of the proposed control schemes with a fuzzy PID controller is performed; the results show that the proposed SDC-based sliding mode controller gave better results.

    This report presents the findings of the annual inspection and radiological survey of the Piqua, Ohio, Decommissioned Reactor Site (site). The decommissioned nuclear power demonstration facility was inspected and surveyed on April 15, 2016. The site, located on the east bank of the Great Miami River in Piqua, Ohio, was in fair physical condition. There is no requirement for a follow-up inspection, partly because City of Piqua (City) personnel participated in a March 2016 meeting to address reoccurring safety concerns. Radiological survey results from 104 locations revealed no removable contamination. One direct beta activity reading in a floor drain on the 56-foot level (1674 disintegrations per minute [dpm]/100 square centimeters [cm2]) exceeded the minimum detectable activity (MDA). Beta activity has been detected in the past at this floor drain. The reading was well below the action level of 5000 dpm/100 cm2.

    We present results for the first three years of OzDES, a six-year program to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the Anglo-Australian Telescope. OzDES is a multi-object spectroscopic survey targeting multiple types of targets at multiple epochs over a multi-year baseline, and is one of the first multi-object spectroscopic surveys to dynamically include transients into the target list soon after their discovery. At the end of three years, OzDES has spectroscopically confirmed almost 100 supernovae, and has measured redshifts for 17,000 objects, including the redshifts of 2,566 supernova hosts. We examine how our ability to measure redshifts for targets of various types depends on signal-to-noise, magnitude, and exposure time, finding that our redshift success rate increases significantly at a signal-to-noise of 2 to 3 per 1-A° ngstrom bin. We also find that the change in signal-to-noise with exposure time closely matches the Poisson limit for stacked exposures as long as 10 hours.We use these results to predict the redshift yield of the full OzDES survey, as well as the potential yields of future surveys on other facilities such as 4MOST, PFS, and MSE. This work marks the first OzDES data release, comprising 15,327 redshifts. OzDES is on target to obtain over 30,000 redshifts over the six-year duration of the survey, including a yield of approximately 5,700 supernova host-galaxy redshifts.

    Full Text Available The objective of this article is to optimize parameters of a hybrid sliding mode controller based on fireworks algorithm for a nonlinear inverted pendulum system. The proposed controller is a combination of two modified types of the classical sliding mode controller, namely, baseline sliding mode controller and fast output sampling discrete sliding mode controller. The simulation process is carried out with MATLAB/Simulink. The results are compared with a published hybrid method using proportional–integral–derivative and linear quadratic regulator controllers. The simulation results show a better performance of the proposed controller.

    2016-01-01

    Full Text Available The two-dimensional (2D discrete Fourier transform (DFT in the sliding window scenario has been successfully used for numerous applications requiring consecutive spectrum analysis of input signals. However, the results of conventional sliding DFT algorithms are potentially unstable because of the accumulated numerical errors caused by recursive strategy. In this letter, a stable 2D sliding fast Fourier transform (FFT algorithm based on the vector radix (VR 2 × 2 FFT is presented. In the VR-2 × 2 FFT algorithm, each 2D DFT bin is hierarchically decomposed into four sub-DFT bins until the size of the sub-DFT bins is reduced to 2 × 2; the output DFT bins are calculated using the linear combination of the sub-DFT bins. Because the sub-DFT bins for the overlapped input signals between the previous and current window are the same, the proposed algorithm reduces the computational complexity of the VR-2 × 2 FFT algorithm by reusing previously calculated sub-DFT bins in the sliding window scenario. Moreover, because the resultant DFT bins are identical to those of the VR-2 × 2 FFT algorithm, numerical errors do not arise; therefore, unconditional stability is guaranteed. Theoretical analysis shows that the proposed algorithm has the lowest computational requirements among the existing stable sliding DFT algorithms.

    Pandey, Achala; Agrawal, Rekha; Mandloi, Ravindra S.; Sarkar, Biswaroop

    2017-08-01

    This paper presents a new kind of adaptive reaching law for sliding mode control of Dynamic Voltage Restorer (DVR). Such an adaptive reaching law follows under-damped sinusoidal nature that causes the initial state to reach the sliding regime in extremely less time with negligible chattering. Moreover, it is robust in the sense the trajectory does not deviate from the sliding surface. This new approach is developed and successfully applied to DVR. The simulation results are presented that show its robustness.

  5. Placebo use in the United kingdom: results from a national survey of primary care practitioners.

    Directory of Open Access Journals (Sweden)

    Jeremy Howick

    Full Text Available OBJECTIVES: Surveys in various countries suggest 17% to 80% of doctors prescribe 'placebos' in routine practice, but prevalence of placebo use in UK primary care is unknown. METHODS: We administered a web-based questionnaire to a representative sample of UK general practitioners. Following surveys conducted in other countries we divided placebos into 'pure' and 'impure'. 'Impure' placebos are interventions with clear efficacy for certain conditions but are prescribed for ailments where their efficacy is unknown, such as antibiotics for suspected viral infections. 'Pure' placebos are interventions such as sugar pills or saline injections without direct pharmacologically active ingredients for the condition being treated. We initiated the survey in April 2012. Two reminders were sent and electronic data collection closed after 4 weeks. RESULTS: We surveyed 1715 general practitioners and 783 (46% completed our questionnaire. Our respondents were similar to those of all registered UK doctors suggesting our results are generalizable. 12% (95% CI 10 to 15 of respondents used pure placebos while 97% (95% CI 96 to 98 used impure placebos at least once in their career. 1% of respondents used pure placebos, and 77% (95% CI 74 to 79 used impure placebos at least once per week. Most (66% for pure, 84% for impure respondents stated placebos were ethical in some circumstances. CONCLUSION AND IMPLICATIONS: Placebo use is common in primary care but questions remain about their benefits, harms, costs, and whether they can be delivered ethically. Further research is required to investigate ethically acceptable and cost-effective placebo interventions.

    Full Text Available The purpose of this paper is to presents results from two empirical surveys concerning selected factors which can be connected to customer orientation, performance and competitiveness of firms. The purpose of the surveys was also to reveal potential differences between sectors arising from not only the different influences of internal but as well as external environment. A survey instrument was developed to analyse the relationship between several variables measuring customer orientation of surveyed firms and between these factors and level of financial performance. Several statistical methods were applied to analyse the data, specifically descriptive statistics (means and standard deviations, one-way analysis of variance (ANOVA with Bonferroni post-hoc test using financial performance for clustering firms and for assessment of potential differences of customer orientation criteria evaluation and Spearman rank correlation coefficients to assess the linear bivariate relationship between customer orientation variables. The results of ANOVA show that only the innovativeness is distinctive distinguishing criteria in conformity with the indicators of financial prosperity and that there are some differences between companies from two groups of sectors within the managers’ perception of customer orientation criteria performance.

    Background: Medical physicists are essential members of the radiation oncology team. Given the increasing complexity of radiotherapy delivery, it is important to ensure adequate training and staffing. The aim of the present study was to update a similar survey from 2008 and assess the situation of medical physicists in the large and diverse Asia Pacific region. Methods: Between March and July 2011, a survey on profession and practice of radiation oncology medical physicists (ROMPs) in the Asia Pacific region was performed. The survey was sent to senior physicists in 22 countries. Replies were received from countries that collectively represent more than half of the world’s population. The survey questions explored five areas: education, staffing, work patterns including research and teaching, resources available, and job satisfaction. Results and discussion: Compared to a data from a similar survey conducted three years ago, the number of medical physicists in participating countries increased by 29% on average. This increase is similar to the increase in the number of linear accelerators, showing that previously identified staff shortages have yet to be substantially addressed. This is also highlighted by the fact that most ROMPs are expected to work overtime often and without adequate compensation. While job satisfaction has stayed similar compared to the previous survey, expectations for education and training have increased somewhat. This is in line with a trend towards certification of ROMPs. Conclusion: As organisations such as the International Labour Organization (ILO) start to recognise medical physics as a profession, it is evident that despite some encouraging signs there is still a lot of work required towards establishing an adequately trained and resourced medical physics workforce in the Asia Pacific region.

    2015-02-01

    From July to August 2014, Epilepsia conducted an online survey seeking opinions that explained the discrepancy between the incidence and prevalence of epilepsy in lower income countries. Data on cumulative incidence suggest a higher rate of active epilepsy than reported in lifetime prevalence surveys. This study reports the findings of that poll addressing the proposal in our Controversy in Epilepsy series that it could be from increased death rates. The survey consisted of a question addressing possible reasons to explain the discrepancy between the incidence and prevalence of epilepsy. Another four questions addressed demographic information. There were 34 responders who completed the survey. Half (50%) of the responders felt that the discrepancy between cumulative incidence and lifetime prevalence was due to lack of uniform definitions and misclassification of patients in study design, 23.5% said the discrepancy was due to a higher mortality from diseases and conditions such as trauma and infections associated with epilepsy, 23.5% indicated that the stigma of epilepsy prevented people from acknowledging their disease in prevalence surveys, and 2.9% felt it was from poor access to qualified medical personal and utilization of medical treatments that increased death rates directly related to epilepsy. Within the limitations of sample size, the results of this survey support that the discrepancy between the incidence and prevalence of epilepsy in lower income regions of the world is due to problems in acquiring the data and stigma rather than higher mortality from diseases associated with epilepsy and repeated seizures.

    Zhang, J; Syh, J; Syh, J; White, M; Patel, B; Song, X; Wu, H [Willis-Knighton Cancer Center, Shreveport, LA (United States)

    2014-06-01

    Purpose: This study summarizes the results of an initial radiation survey of the Willis-Knighton Cancer Center in Shreveport, Louisiana. The facility houses an IBA ProteusOne compact single room proton therapy unit coupled with a C230 cyclotron that operates at a maximum energy of 230 MeV. Methods: A calibrated survey meter was used for the photon measurements to obtain reliable results. A neutron detector was used as the measuring instrument for neutrons. The locations of the survey and measurements were planned carefully in order to get a proper evaluation of the facility shielding configuration. The walls, ceiling, vault entrance, and the adjacent environment were each surveyed with suitable measurement instruments. A total of 22 locations were chosen for radiation survey. Dose equivalent values were calculated for both the photon and the neutron radiation using measured data. Results: All measured dose values are presented in millisievert per year. The highest dose measured at the vault entrance is 0.34 mSv/year. A dedicated shielding door was not present at the time of the measurement. The vault entrance area is considered as a controlled area. The shielding design goals are not to exceed 5 mSv/year for the controlled area and 1 mSv/year the uncontrolled area. The total combined neutron and photon dose equivalent values were found to be compliant with the Louisiana Department of Environmental Quality radiation protection regulatory codes. Conclusion: In our efforts to evaluate the radiation levels at the Willis-Knighton Cancer Center proton treatment facility, we have found that all the measured values of the radiation shielding are below the critical radiation limits per year. Since the total dose measured at the vault entrance is below the shielding design goal, a shielding door is not required at this proton treatment vault.

    2011-01-01

    Full Text Available Background: In histopathology, the quantitative assessment of various morphologic features is based on methods originally conceived on specific areas observed through the microscope used. Failure to reproduce the same reference field of view using a different microscope will change the score assessed. Visualization of a digital slide on a screen through a dedicated viewer allows selection of the magnification. However, the field of view is rectangular, unlike the circular field of optical microscopy. In addition, the size of the selected area is not evident, and must be calculated. Materials and Methods: A digital slide morphometric system was conceived to reproduce the various methods published for assessing tumor budding in colorectal cancer. Eighteen international experts in colorectal cancer were invited to participate in a web-based study by assessing tumor budding with five different methods in 100 digital slides. Results: The specific areas to be tested by each method were marked by colored circles. The areas were grouped in a target-like pattern and then saved as an .xml file. When a digital slide was opened, the .xml file was imported in order to perform the measurements. Since the morphometric tool is composed of layers that can be freely moved on top of the digital slide, the technique was named digital slide dynamic morphometry. Twelve investigators completed the task, the majority of them performing the multiple evaluations of each of the cases in less than 12 minutes. Conclusions: Digital slide dynamic morphometry has various potential applications and might be a useful tool for the assessment of histologic parameters originally conceived for optical microscopy that need to be quantified.

  11. Flexible Structural Design for Side-Sliding Force Reduction for a Caterpillar Climbing Robot

    2012-11-01

    Full Text Available Due to sliding force arising from the closed chain mechanism among the adhering points of a climbing caterpillar robot (CCR, a sliding phenomenon will happen at the adhering points, e.g., the vacuum pads or claws holding the surface. This sliding force makes the attachment of the climbing robot unsteady and reducesthe motion efficiency. According to the new bionic research on the soft-body structure of caterpillars, some flexible structures made of natural rubber bars are applied in CCRs correspondingly as an improvement to the old rigid mechanical design of the robotic structure. This paper firstly establishes the static model of the sliding forces, the distortion of flexible bars and the driving torques of joints. Then, a method to reduce the sliding force by exerting a compensating angle to an active joint of the CCR is presented. The analyses and experimental results indicate that the flexible structure and the compensating angle method can reduce the sliding forces remarkably.

    Full Text Available A key problem in gravity dam design is providing enough stability to prevent slide, and the difficulty increases if there are several weak structural planes in the dam foundation. Overload and material weakening were taken into account, and a finite difference strength reserve method with partial safety factors based on the reliability method was developed and used to study the anti-slide stability of a concrete gravity dam on a complicated foundation with multiple slide planes. Possible slide paths were obtained, and the stability of the foundation with possible failure planes was evaluated through analysis of the stress distribution characteristics. The results reveal the mechanism and process of sliding due to weak structural planes and their deformations, and provide a reference for anti-slide stability analysis of gravity dams in complicated geological conditions.

    2016-03-01

    Full Text Available Sliding Mode Controller (SMC is a simple method and powerful technique to design a robust controller for nonlinear systems. It is an effective tool with acceptable performance. The major drawback is a classical Sliding Mode controller suffers from the chattering phenomenon which causes undesirable zigzag motion along the sliding surface. To overcome the snag of this classical approach, many methods were proposed and implemented. In this work, a Fuzzy controller was added to classical Sliding Mode controller in order to reduce the impact chattering problem. The new structure is called Sliding Mode Fuzzy controller (SMFC which will also improve the properties and performance of the classical Sliding Mode controller. A single inverted pendulum has been utilized for testing the design of the proposed controller. Programming and Simulink by Matlab have been used for the simulation results.

    2016-04-01

    This paper investigates global projective synchronization of nonidentical fractional-order neural networks (FNNs) based on sliding mode control technique. We firstly construct a fractional-order integral sliding surface. Then, according to the sliding mode control theory, we design a sliding mode controller to guarantee the occurrence of the sliding motion. Based on fractional Lyapunov direct methods, system trajectories are driven to the proposed sliding surface and remain on it evermore, and some novel criteria are obtained to realize global projective synchronization of nonidentical FNNs. As the special cases, some sufficient conditions are given to ensure projective synchronization of identical FNNs, complete synchronization of nonidentical FNNs and anti-synchronization of nonidentical FNNs. Finally, one numerical example is given to demonstrate the effectiveness of the obtained results. Copyright © 2016 Elsevier Ltd. All rights reserved.

  15. Adaptive Tracking and Obstacle Avoidance Control for Mobile Robots with Unknown Sliding

    2012-11-01

    Full Text Available An adaptive control approach is proposed for trajectory tracking and obstacle avoidance for mobile robots with consideration given to unknown sliding. A kinematic model of mobile robots is established in this paper, in which both longitudinal and lateral sliding are considered and processed as three time-varying parameters. A sliding model observer is introduced to estimate the sliding parameters online. A stable tracking control law for this nonholonomic system is proposed to compensate the unknown sliding effect. From Lyapunov-stability analysis, it is proved, regardless of unknown sliding, that tracking errors of the controlled closed-loop system are asymptotically stable, the tracking errors converge to zero outside the obstacle detection region and obstacle avoidance is guaranteed inside the obstacle detection region. The efficiency and robustness of the proposed control system are verified by simulation results.

    2015-01-01

    Full Text Available An adaptive global sliding mode control (AGSMC using RBF neural network (RBFNN is proposed for the system identification and tracking control of micro-electro-mechanical system (MEMS gyroscope. Firstly, a new kind of adaptive identification method based on the global sliding mode controller is designed to update and estimate angular velocity and other system parameters of MEMS gyroscope online. Moreover, the output of adaptive neural network control is used to adjust the switch gain of sliding mode control dynamically to approach the upper bound of unknown disturbances. In this way, the switch item of sliding mode control can be converted to the output of continuous neural network which can weaken the chattering in the sliding mode control in contrast to the conventional fixed gain sliding mode control. Simulation results show that the designed control system can get satisfactory tracking performance and effective estimation of unknown parameters of MEMS gyroscope.

    The features of an electrical interaction between surface streamers (thin current filaments) sliding on a liquid and liquid itself are still unknown in many details. This paper presents the experimental results on properties of the surface streamers sliding on water with different conductivity (distilled and tap water). The streamers were initiated with a sharpened thin metallic needle placed above the liquid and stressed with a periodical or pulsed high voltage. Two electrode systems were used and tested. The first of them provides in advance the existence of the longitudinal electric field above the water. The second one imitates the electrode geometry of a pin-to-plane dielectric barrier discharge in which the barrier is a thick layer of liquid. The electrical and optical characteristics of streamers were complemented with data on the spectroscopic measurements. It was revealed that surface streamers on water have no spatial memory.

  18. Hypersonic sliding target tracking in near space

    Xiang-yu Zhang

    2015-12-01

    Full Text Available To improve the tracking accuracy of hypersonic sliding target in near space, the influence of target hypersonic movement on radar detection and tracking is analyzed, and an IMM tracking algorithm is proposed based on radial velocity compensating and cancellation processing of high dynamic biases under the earth centered earth fixed (ECEF coordinate. Based on the analysis of effect of target hypersonic movement, a measurement model is constructed to reduce the filter divergence which is caused by the model mismatch. The high dynamic biases due to the target hypersonic movement are approximately compensated through radial velocity estimation to achieve the hypersonic target tracking at low systematic biases in near space. The high dynamic biases are further eliminated by the cancellation processing of different radars, in which the track association problem can be solved when the dynamic biases are low. An IMM algorithm based on constant acceleration (CA, constant turning (CT and Singer models is used to achieve the hypersonic sliding target tracking in near space. Simulation results show that the target tracking in near space can be achieved more effectively by using the proposed algorithm.

    The semi-circumumbilical incision for treatment of infantile hypertrophic pyloric stenosis, described by Tan and Bianchi (Tan KC, Bianchi A. Circumumbilical incision for pyloromyotomy. Br J Surg 1986;73:399), does not allow a comfortable access to the pylorus in up to 30% of cases, resulting, not infrequently, in unexpected seromuscular lacerations. To get easier access to the pylorus we have performed the Ramstedt pyloromyotomy through a sliding umbilical window after full-circumumbilical incision in 13 initial consecutive cases. Skin was incised along the entire circumference of the umbilicus, and then was undermined, creating a circular subcutaneous space, 8 cm in diameter. The umbilical window, about 1.5 cm in diameter, was slid diagonally toward the right upper quadrant, by shifting a pair of muscle retractors, 3 to 4 cm from the umbilicus, with the umbilicus left in its original position under the slid skin. Through the sliding window at the right upper quadrant, the abdomen was entered, and the hypertrophied pylorus was identified within the center of the window. Then the pyloromyotomy was performed intracorporeally with ease. In all 13 infants, an adequate pyloromyotomy was safely performed. The wound healed primarily in all cases, without leaving conspicuous scar, subcutaneous abscess formation, or incisional hernia. The postoperative course was quite uneventful in each. This new approach allows far easier access to and exposure of the pylorus, and facilitates a safe intracorporeal pyloromyotomy, and achieves an excellent cosmetic outcome.

    The mitotic spindle is a microtubule (MT)-based molecular machine that serves for equal segregation of chromosomes during cell division. The formation of the mitotic spindle requires the activity of MT motors, including members of the kinesin-14 family. Although evidence suggests that kinesins-14 act by driving the sliding of MT bundles in different areas of the spindle, such sliding activity had never been demonstrated directly. To test the hypothesis that kinesins-14 can induce MT sliding in living cells, we developed an in vivo assay, which involves overexpression of the kinesin-14 family member Drosophila Ncd in interphase mammalian fibroblasts. We found that green fluorescent protein (GFP)-Ncd colocalized with cytoplasmic MTs, whose distribution was determined by microinjection of Cy3 tubulin into GFP-transfected cells. Ncd overexpression resulted in the formation of MT bundles that exhibited dynamic "looping" behavior never observed in control cells. Photobleaching studies and fluorescence speckle microscopy analysis demonstrated that neighboring MTs in bundles could slide against each other with velocities of 0.1 microm/s, corresponding to the velocities of movement of the recombinant Ncd in in vitro motility assays. Our data, for the first time, demonstrate generation of sliding forces between adjacent MTs by Ncd, and they confirm the proposed roles of kinesins-14 in the mitotic spindle morphogenesis.

    The purpose of this study was to test the possible differences in centric slide values between different Angle's classes of occlusion. The study included 98 participants divided into four groups: Angle's class I, Angle's class II, subdivision 1, Angle's class II, subdivision 2 and Angle's class III. All recordings were obtained using an ultrasound jaw tracking device with six degrees of freedom. The distance between the maximum intercuspation (reference position) and the centric occlusion was recorded at the condylar level. Anteroposterior, superoinferior and transversal distance of the centric slide were calculated for each participant, and the data were statistically analyzed (analysis of variance and Newman-Keuls post hoc test). No statistically significant difference was found in the anteroposterior and transversal distance of the centric slide between tested groups, while Angle's class II, subdivision 2 showed smaller vertical amount of the centric slide compared to Angle's class I and class II, subdivision 1. None of the 98 participants showed coincidence of centric occlusion and maximum intercuspation. Our results suggest that coincidence of the maximum intercuspation with the centric occlusion should not be expected. Smaller extent of the vertical distance of the centric slide could be morphological and a functional expression characteristic of the Angle's class II, subdivision 2. Copyright © 2015 Elsevier GmbH.

    Background Kawasaki disease (KD) has been reported in many countries. However, the incidence of KD in Mongolia is not known. This is the first report of incident cases of KD in Mongolia, which were identified using data from 2 nationwide surveys. Methods Two nationwide retrospective surveys were conducted: medical histories were collected from patients aged 0 to 16 years who were hospitalized countrywide between 1996 and 2008. Hospital records for these patients were also reviewed. Nationwide training seminars on KD were conducted before each survey. Results For the nationwide surveys, the participation rates among all hospitals with pediatric wards were 97% and 94%. Inpatient medical histories from 1996 through 2008 were reviewed, and, among children younger than 16 years, 9 patients with KD were investigated. The age of KD patients ranged from 1.4 to 14 years; 7 of 9 patients were male. Six (67%) patients fulfilled all 6 clinical diagnostic criteria; the other 3 (33%) were defined as having KD based on the presence of 5 such criteria. Fever persisting 5 or more days, bilateral conjunctival congestion, and changes of the lips and oral cavity were the most common symptoms, and cervical lymphadenopathy was the least common symptom. Cardiac sequelae developed in 5 of the patients, 4 of whom were older than 10 years. Conclusions The results of these nationwide surveys reveal that KD cases do exist in Mongolia. However, knowledge of KD among Mongolian pediatricians is likely to be poor. Thus, there is a need to augment their understanding to improve management of KD patients. Further studies are crucial to clarify the epidemiologic characteristics of KD in Mongolia. PMID:21691035

    The primary objective of this study was to investigate current powerlifting training methods in light of anecdotal evidence purporting increased similarity with the explosive training practices of weightlifters. The study also assessed the prevalence of contemporary training practices frequently recommended for powerlifters in the popular literature. A 20-item survey was distributed to 32 elite British powerlifters at an International competition. The subject group included multiple national, international, and commonwealth champions and record holders. Based on 2007 competition results, the average Wilks score of the group was 450.26 +/- 34.7. The response rate for the surveys was 88% (28 of 32). The survey was sectioned into 6 areas of inquiry: a) repetition speed, b) explosive training load, c) resistance materials used, d) adjunct power training methods, e) exercise selection, and f) training organization. The results demonstrate that the majority of powerlifters train with the intention to explosively lift maximal and submaximal loads (79 and 82%, respectively). Results revealed that 39% of the lifters regularly used elastic bands and that 57% incorporated chains in their training. Evidence for convergence of training practices between powerlifters and weightlifters was found when 69% of the subjects reported using the Olympic lifts or their derivatives as part of their powerlifting training. Collectively, the results demonstrate that previous notions of how powerlifters train are outdated. Contemporary powerlifters incorporate a variety of training practices that are focused on developing both explosive and maximal strength.

    Full Text Available Abstract Background The spreading of whole slide imaging or digital slide systems in pathology as an innovative technique seems to be unstoppable. Successful introduction of digital slides in education has played a crucial role to reach this level of acceptance. Practically speaking there is no university institute where digital materials are not built into pathology education. At the 1st. Department of Pathology and Experimental Cancer Research, Semmelweis University optical microscopes have been replaced and for four years only digital slides have been used in education. The aim of this paper is to summarize our experiences gathered with the installation of a fully digitized histology lab for graduate education. Methods We have installed a digital histology lab with 40 PCs, two slide servers - one for internal use and one with external internet access. We have digitized hundreds of slides and after 4 years we use a set of 126 slides during the pathology course. A Student satisfaction questionnaire and a Tutor satisfaction questionnaire have been designed, both to be completed voluntarily to have feed back from the users. The page load statistics of the external slide server were evaluated. Results The digital histology lab served ~900 students and ~1600 hours of histology practice. The questionnaires revealed high satisfaction with digital slides. The results also emphasize the importance of the tutors' attitude towards digital microscopy as a factor influencing the students' satisfaction. The constantly growing number of page downloads from the external server confirms this satisfaction and the acceptance of digital slides. Conclusions We are confident, and have showed as well, that digital slides have got numerous advantages over optical slides and are more suitable in education.

    We present a magnetic survey conducted in the offshore region between Cabo da Roca and Sesimbra (mouth of Tagus River, Portugal). Strong magnetic anomalies are recognized in this area since a first marine survey in 1958 (Allan, 1965) and by further aeromagnetic survey (c.f. Silva et al, 2000). The anomalies have been linked to Cretaceous magmatic events related to the Upper Cretaceous Sintra magmatic complex and Lisbon volcanic complex, but their geometry and extension has yet not been resolved. The aim of the present survey was to unravel the location, geometry and type of the magnetic sources, thus contributing for the characterization of the main magmatic and tectonic features in the region. The survey was conducted in two legs (October 2014 and June 2015), consisting of 27 lines and 6 tielines, extending up to 40 km from the coast. The line spacing was 1 mile for the main lines and 5-6 miles for the tielines. The bathymetry of the surveyed area varies from very shallow (about 10 m) to near 3000 m. Total field was measured with a G-882 Cesium marine magnetometer of Geometrics (self-oscillating split-beam Cesium vapor), with frequency of acquisition of 10 Hz. Layback was real-time corrected using the acquisition software. Noise was removed by despike in Magpick software (Geometrics), and further processing was done using Oasis montaj (Geosoft) software. Data were subtracted of IGRF values and levelled by tielines to retrieve the final map of anomalies. Several punctual and linear anomalies with varying amplitude and wavenumber were identified, which cannot be explained by bathymetric variation; therefore they must then be due to the presence of higher susceptibility, likely volcanic rocks, and to structural inheritance associated with rifting and Alpine orogeny. The highest anomaly corresponds to the Cabo Raso positive magnetic anomaly, with maximum and minimum of 2800 nT and -1350 nT, respectively. This anomaly, already surveyed in 1958, has been compared to a

    Surveys in various countries suggest 17% to 80% of doctors prescribe 'placebos' in routine practice, but prevalence of placebo use in UK primary care is unknown. We administered a web-based questionnaire to a representative sample of UK general practitioners. Following surveys conducted in other countries we divided placebos into 'pure' and 'impure'. 'Impure' placebos are interventions with clear efficacy for certain conditions but are prescribed for ailments where their efficacy is unknown, such as antibiotics for suspected viral infections. 'Pure' placebos are interventions such as sugar pills or saline injections without direct pharmacologically active ingredients for the condition being treated. We initiated the survey in April 2012. Two reminders were sent and electronic data collection closed after 4 weeks. We surveyed 1715 general practitioners and 783 (46%) completed our questionnaire. Our respondents were similar to those of all registered UK doctors suggesting our results are generalizable. 12% (95% CI 10 to 15) of respondents used pure placebos while 97% (95% CI 96 to 98) used impure placebos at least once in their career. 1% of respondents used pure placebos, and 77% (95% CI 74 to 79) used impure placebos at least once per week. Most (66% for pure, 84% for impure) respondents stated placebos were ethical in some circumstances. Placebo use is common in primary care but questions remain about their benefits, harms, costs, and whether they can be delivered ethically. Further research is required to investigate ethically acceptable and cost-effective placebo interventions.

    Background Inhalation incidents are an important cause of acute respiratory symptoms, but little is known about how these incidents affect chronic respiratory health. Methods We assessed reported inhalation incidents among 3,763 European Community Respiratory Health Survey (ECRHS) participants with and without cough, phlegm, asthma, wheezing or bronchial hyperresponsiveness. We then examined whether inhalation incidents during the 9-year ECRHS follow-up period were associated with a new onset of any of these respiratory outcomes among 2,809 participants who were free of all five outcomes at the time of the baseline ECRHS survey. Results Inhalation incidents were reported by 5% of participants, with higher percentages reported among individuals with asthma-related outcomes at the time of the baseline survey. Among participants without symptoms at baseline, our analyses generated non-statistically significant elevated estimates of the risk of cough, phlegm, asthma and wheezing and a non-statistically significant inverse estimate of the risk of bronchial hyperresponsiveness among participants who reported an inhalation incident compared to those without such an event reported. Discussion Our findings provide limited evidence of an association between inhalation incidents and asthma-related symptoms. These data could be affected by differences in the reporting of inhalation incidents according to symptom status at the time of the baseline survey; they should thus be interpreted with caution.

    To identify the prevalence and characteristics of faculty leadership development programs (LDPs) offered by North American academic health centers (AHCs) and to uncover gaps in leadership training. Faculty development/affairs deans of the 161 Association of American Medical Colleges member schools were surveyed in 2015 on their approach to faculty leadership training. For AHCs delivering their own training, the survey included questions about LDP participants, objectives, curriculum, delivery, resources, and evaluation. The literature on leadership and leadership development was used to develop a taxonomy of leadership competencies, which formed the basis of the survey questions related to program content. Survey results were analyzed with descriptive statistics and chi-square analysis for categorical data. Of the 94 respondents (response rate 58%), 93 provided some form of leadership training and 61 provided a formal internal faculty LDP. Content was variable and rarely based on a specific leadership competency model. Although programs described innovative approaches to learning, lectures and case discussions were the predominant approaches. Evaluation beyond participant satisfaction was uncommon. Faculty LDPs were common, with some programs describing elements informed by the leadership literature. However, nationally programs can improve by basing content on a leadership competency model, incorporating multiple approaches to teaching, and implementing more rigorous program evaluation.

    Replacing oil and electric heating systems with innovative heating systems (IHSs) such as bedrock heat pumps, district heating system, and pellet boilers will significantly reduce greenhouse gas emission from Swedish detached houses. However, realizing this potential depends on homeowners' adoption decision, which is influenced by their need, awareness and perception of the advantages associated with the IHSs. In this context, we conducted mail-in questionnaire surveys of 1,500 Swedish homeowners, selected through stratified random sampling method, in Fall 2004, Spring 2007, and Summer 2008. A response rate of 42%, 48% and 37% was obtained in the 2004, 2007 and 2008 surveys, respectively. One of the aims of the series of surveys was to find out if external factors such as provision of investment subsidies and mass media discussion of climate change issues had influenced homeowners awareness and perception of the advantages associated with the IHSs. Results showed that there was no appreciable change in homeowners' perceptions between the years surveyed. They consistently gave higher priority to economic factors over environmental factors in their decision to install a new heating system. Heat pumps were best perceived with respect to the annual energy cost of heating, environmental benignity, increased market value of the house, and low greenhouse gas emissions. Respondents felt that pellet boilers had the lowest investment cost, while district heating system had the perceived advantage of functional reliability.

    Since the 1970s, the federal government has spearheaded major national education programs to reduce the burden of chronic diseases in the United States. These prevention and disease management programs communicate critical information to the public, those affected by the disease, and health care providers. The National Diabetes Education Program (NDEP), the leading federal program on diabetes sponsored by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), uses primary and secondary quantitative data and qualitative audience research to guide program planning and evaluation. Since 2006, the NDEP has filled the gaps in existing quantitative data sources by conducting its own population-based survey, the NDEP National Diabetes Survey (NNDS). The NNDS is conducted every 2–3 years and tracks changes in knowledge, attitudes and practice indicators in key target audiences. This article describes how the NDEP has used the NNDS as a key component of its evaluation framework and how it applies the survey results for strategic planning and program improvement. The NDEP's use of the NNDS illustrates how a program evaluation framework that includes periodic population-based surveys can serve as an evaluation model for similar national health education programs.

    Biomedical informatics programs exist in many countries. Some analyses of the skills needed and of recommendations for curricular content for such programs have been published. However, not much is known of the job profiles and job careers of their graduates. To analyse the job profiles and job careers of 175 graduates of the biomedical informatics bachelor and master program of the Tyrolean university UMIT. Survey of all biomedical informatics students who graduated from UMIT between 2001 and 2013. Information is available for 170 graduates. Eight percent of graduates are male. Of all bachelor graduates, 86% started a master program. Of all master graduates, 36% started a PhD. The job profiles are quite diverse: at the time of the survey, 35% of all master graduates worked in the health IT industry, 24% at research institutions, 9% in hospitals, 9% as medical doctors, 17% as informaticians outside the health care sector, and 6% in other areas. Overall, 68% of the graduates are working as biomedical informaticians. The results of the survey indicate a good job situation for the graduates. The job opportunities for biomedical informaticians who graduated with a bachelor or master degree from UMIT seem to be quite good. The majority of graduates are working as biomedical informaticians. A larger number of comparable surveys of graduates from other biomedical informatics programs would help to enhance our knowledge about careers in biomedical informatics.

    Little is known about how medical educators perceive their own expertise, needs and challenges in relation to medical education. To survey an international community of medical educators with a focus on: (1) their expertise, (2) their need for training and (3) perceived challenges. A web-based survey comprising closed and open free-text questions was sent to 2200 persons on the mailing list of the Association for Medical Education in Europe. Of the 2200 medical educators invited to participate, 860 (39%) from 76 different countries took part in the survey. In general, their reported areas of expertise mainly comprised principles of teaching, communication skills training, stimulation of students in self-directed learning and student assessment. Respondents most often indicated a need for training with respect to development in medical-education-research methodology, computer-based training, curriculum evaluation and curriculum development. In the qualitative analysis of 1836 free-text responses concerning the main challenges faced, respondents referred to a lack of academic recognition, funding, faculty development, time for medical education issues and institutional support. The results of this survey indicate that medical educators face several challenges, with a particular need for more academic recognition, funding and academic qualifications in medical education.

  13. Fractional-Order Fast Terminal Sliding Mode Control for a Class of Dynamical Systems

    2013-01-01

    Full Text Available This paper introduces a novel fractional fast terminal sliding mode control strategy for a class of dynamical systems with uncertainty. In this strategy, a fractional-order sliding surface is proposed, the corresponding control law is derived based on Lyapunov stability theory to guarantee the sliding condition, and the finite time stability of the closeloop system is also ensured. Further, to achieve the equivalence between convergence rate and singularity avoidance, a fractional-order nonsingular fast terminal sliding mode controller is studied and the stability is presented. Finally, numerical simulation results are presented to illustrate the effectiveness of the proposed method.

    Toyama, Shigehiro; Ikeda, Fujio

    This paper presents a sliding mode controller of semi-active suspension systems. The sliding mode controller is designed by the describing function method so that a switching function is enforced into a desired limit cycle instead of a perfect sliding mode. Although the proposed sliding mode controller cannot generate the limit cycle as desired because of the passive constraint of controllable dampers, restricting the switching function in the vicinity of the origin can suppress the deterioration due to the passive constraint, such as increase of jerk of the sprung mass. Finally, simulation results show the effectiveness of the proposed controller.

    As part of the VISTA Science Verification programme, a large set of images in Orion was obtained at five near-infrared wavelength bands, from 0.9 to 2.2 μm. The resulting multi-band catalogue contains approximately three million sources, allowing investigation of various issues concerning star and brown dwarf formation, such as a) the difference in the shape of the substellar mass function in a cluster vs. non-clustered environment, b) the influence of massive OB stars on the process of brown dwarf formation, c) the size and morphology of dust envelopes around protostars, and d) the comparative role of mass and environment on the evolution of circumstellar discs. The data from the VISTA Orion Survey, including catalogues, are available to the community. In this article we present an overview of selected science results that have emerged so far from this survey.

    Results are presented from an extensive survey of stellar X-ray emission, using the Einstein Observatory. Over 140 stars have been detected to date, throughout the H-R diagram, thus showing that soft X-ray emission is the norm rather than the exception for stars in general. This finding is strongly at odds with pre-Einstein expectations based on standard acoustic theories of coronal heating. Typical examples of stellar X-ray detections and an overview of the survey data are presented. In combination with recent results from solar X-ray observations, the new Einstein data argue for the general applicability of magnetic field-related coronal heating mechanisms.

    Consumer confidence in food safety appears to be under pressure as a result of several food scandals and food scares in recent years. Regaining the trust of food consumers in food production and food products is talk of the town in both government buildings and agribusiness offices. Instead of talking about consumers, this article is first and foremost about what consumers themselves think and feel about food safety. The foundation of this research is a survey among nearly 1100 Dutch consumer...

    We present new far-IR photometry results on 131 proto-stars from the Herschel Orion Protostar Survey (HOPS). HOPS is a 200-hour Herschel key program that will systematically survey 286 protostars encompassing a wide range of source luminosities, evolutionary phases, and environments in a single molecular cloud in the 60-210 micron window where we will sample the peak of the thermal emission from the protostellar envelope. We will focus on PACS imaging at 70 and 160 um taken as part of the imaging component of the HOPS program. From these data we extract 70 and 160 um photometry which are then combined with existing ground-based and HST near-IR imaging, IRAC and MIPS 3-24 um photometry and IRS 5-35 um spectra to create 1.6-160 um SEDs. These SEDS are integrated to find the bolometric luminosities and compared to the results of radiative transfer models (Whitney et al. 2003, ApJ, 591, 1049) to constrain the envelope morphologies, envelope densities, and infall rates. Our initial results (Fischer et al. 2010, A&A, 518, L122) on only protostars 4 stars showed a range of evolutionary states for the protostars. In this contribution, we extend our sample to 131 protostars -- the first large survey of its kind in the far-IR. We will examine the distribution of luminosities and SED properties as a function of environment. We will also present preliminary fits to radiative transfer models of the protostars.

    Kawasaki disease (KD) has been reported in many countries. However, the incidence of KD in Mongolia is not known. This is the first report of incident cases of KD in Mongolia, which were identified using data from 2 nationwide surveys. Two nationwide retrospective surveys were conducted: medical histories were collected from patients aged 0 to 16 years who were hospitalized countrywide between 1996 and 2008. Hospital records for these patients were also reviewed. Nationwide training seminars on KD were conducted before each survey. For the nationwide surveys, the participation rates among all hospitals with pediatric wards were 97% and 94%. Inpatient medical histories from 1996 through 2008 were reviewed, and, among children younger than 16 years, 9 patients with KD were investigated. The age of KD patients ranged from 1.4 to 14 years; 7 of 9 patients were male. Six (67%) patients fulfilled all 6 clinical diagnostic criteria; the other 3 (33%) were defined as having KD based on the presence of 5 such criteria. Fever persisting 5 or more days, bilateral conjunctival congestion, and changes of the lips and oral cavity were the most common symptoms, and cervical lymphadenopathy was the least common symptom. Cardiac sequelae developed in 5 of the patients, 4 of whom were older than 10 years. The results of these nationwide surveys reveal that KD cases do exist in Mongolia. However, knowledge of KD among Mongolian pediatricians is likely to be poor. Thus, there is a need to augment their understanding to improve management of KD patients. Further studies are crucial to clarify the epidemiologic characteristics of KD in Mongolia.

    To survey all US medical school clerkship directors (CDs) in neurology and to compare results from a similar survey in 2005. A survey was developed by a work group of the American Academy of Neurology Undergraduate Education Subcommittee, and sent to all neurology CDs listed in the American Academy of Neurology database. Comparisons were made to a similar 2005 survey. Survey response rate was 73%. Neurology was required in 93% of responding schools. Duration of clerkships was 4 weeks in 74% and 3 weeks in 11%. Clerkships were taken in the third year in 56%, third or fourth year in 19%, and fourth year in 12%. Clerkship duration in 2012 was slightly shorter than in 2005 (fewer clerkships of ≥4 weeks, p = 0.125), but more clerkships have moved into the third year (fewer neurology clerkships during the fourth year, p = 0.051). Simulation training in lumbar punctures was available at 44% of schools, but only 2% of students attempted lumbar punctures on patients. CDs averaged 20% protected time, but reported that they needed at least 32%. Secretarial full-time equivalent was 0.50 or less in 71% of clerkships. Eighty-five percent of CDs were "very satisfied" or "somewhat satisfied," but more than half experienced "burnout" and 35% had considered relinquishing their role. Trends in neurology undergraduate education since 2005 include shorter clerkships, migration into the third year, and increasing use of technology. CDs are generally satisfied, but report stressors, including inadequate protected time and departmental support. © 2014 American Academy of Neurology.

  5. Fuzzy-Sliding Mode Force Control Research on Robotic Machining

    Directory of Open Access Journals (Sweden)

    Shou-yan Chen

    2017-01-01

    Full Text Available The low stiffness has limited the applications of robot to machining process. In this paper, a fuzzy-sliding mode control scheme is proposed to manage the oscillation and chatter appearing in machining operation by adjusting the feed rate. The robotic machining dynamics is first analyzed to identify the parameters with focus on the system stiffness and the behavior during machining process. A controller consisting of a fuzzy estimation enginery which can determine the control gain coefficients according to system status and a sliding mode controller which is used to guarantee convergence and global stability of the system is then proposed. Simulations and experiments results show that, in comparison with open loop and fuzzy-PID control scheme, the fuzzy-sliding mode control scheme can reduce the amplitude and period of oscillation.

    the surfaces in an industrial context. In this paper, a number of experimental tests were performed using a novel test rig, called axial sliding test, simulating the contact of surfaces under pure sliding conditions. The aim of the experiments is to evaluate the frictional behavior of a new typology...... of textured surfaces, the so-called multifunctional surfaces, characterized by a plateau area able to bear loads and a deterministic pattern of lubricant pockets. Six surface typologies, namely three multifunctional and three machined using classical processes, were chosen to slide against a mirror....... The results comparison showed clearly how employing multifunctional surfaces can reduce friction forces up to 50 % at high normal loads compared to regularly ground or turned surfaces. Friction coefficients approximately equal to 0.12 were found for classically machined surfaces, whereas the values were 0...

  7. Optimal Sliding Mode Controllers for Attitude Stabilization of Flexible Spacecraft

    Directory of Open Access Journals (Sweden)

    Chutiphon Pukdeboon

    2011-01-01

    Full Text Available The robust optimal attitude control problem for a flexible spacecraft is considered. Two optimal sliding mode control laws that ensure the exponential convergence of the attitude control system are developed. Integral sliding mode control (ISMC is applied to combine the first-order sliding mode with optimal control and is used to control quaternion-based spacecraft attitude manoeuvres with external disturbances and an uncertainty inertia matrix. For the optimal control part the state-dependent Riccati equation (SDRE and optimal Lyapunov techniques are employed to solve the infinite-time nonlinear optimal control problem. The second method of Lyapunov is used to guarantee the stability of the attitude control system under the action of the proposed control laws. An example of multiaxial attitude manoeuvres is presented and simulation results are included to verify the usefulness of the developed controllers.

    This study proposes a sliding mode controller for vehicular traffic flow based on a car-following model to enhance the smoothness and stability of traffic flow evolution. In particular, the full velocity difference (FVD) model is used to capture the characteristics of vehicular traffic flow. The proposed sliding mode controller is designed in terms of the error between the desired space headway and the actual space headway. The stability of the controller is guaranteed using the Lyapunov technique. Numerical experiments are used to compare the performance of sliding mode control (SMC) with that of feedback control. The results illustrate the effectiveness of the proposed SMC method in terms of the distribution smoothness and stability of the space headway, velocity, and acceleration profiles. They further illustrate that the SMC strategy is superior to that of the feedback control strategy, while enabling computational efficiency that can aid in practical applications.

    Amazon Mechanical Turk was used, for the first time, to collect statistically representative survey data from U.S. households on the presence, number, type and usage of refrigerators, freezers, and various “miscellaneous” refrigeration products (wine/beverage coolers, residential icemakers and non-vapor compression refrigerators and freezers), along with household and demographic information. Such products have been poorly studied to date, with almost no information available about shipments, stocks, capacities, energy use, etc. A total of 9,820 clean survey responses were obtained from four distinct surveys deployed in 2012. General refrigeration product survey responses were weighted to demographics in the U.S. Energy Information Administration’s Residential Energy Consumption Survey 2009 dataset. Miscellaneous refrigeration product survey responses were weighted according to demographics of product ownership found in the general refrigeration product surveys. Model number matching for a portion of miscellaneous refrigeration product responses allowed validation of refrigeration product characteristics, which enabled more accurate estimates of the penetrations of these products in U.S. households. We estimated that there were 12.3±1.0 million wine/beverage coolers, 5.5(–3.5,+3.2) million residential icemakers and 2.9(–2.5,+4.5) million non-vapor compression refrigerators in U.S. households in 2012. (All numerical results are expressed with ranges indicating the 95% confidence interval.) No evidence was found for the existence of non-vapor compression freezers. Moreover, we found that 15% of wine/beverage coolers used vapor compression cooling technology, while 85% used thermoelectric cooling technology, with the vast majority of thermoelectric units having capacities of less than 30 wine bottles (approximately 3.5 cubic feet). No evidence was found for the existence of wine/beverage coolers with absorption cooling technology. Additionally, we estimated

    The spreading of whole slide imaging or digital slide systems in pathology as an innovative technique seems to be unstoppable. Successful introduction of digital slides in education has played a crucial role to reach this level of acceptance. Practically speaking there is no university institute where digital materials are not built into pathology education. At the 1st. Department of Pathology and Experimental Cancer Research, Semmelweis University optical microscopes have been replaced and for four years only digital slides have been used in education. The aim of this paper is to summarize our experiences gathered with the installation of a fully digitized histology lab for graduate education. We have installed a digital histology lab with 40 PCs, two slide servers - one for internal use and one with external internet access. We have digitized hundreds of slides and after 4 years we use a set of 126 slides during the pathology course. A Student satisfaction questionnaire and a Tutor satisfaction questionnaire have been designed, both to be completed voluntarily to have feed back from the users. The page load statistics of the external slide server were evaluated. The digital histology lab served ~900 students and ~1600 hours of histology practice. The questionnaires revealed high satisfaction with digital slides. The results also emphasize the importance of the tutors' attitude towards digital microscopy as a factor influencing the students' satisfaction. The constantly growing number of page downloads from the external server confirms this satisfaction and the acceptance of digital slides. We are confident, and have showed as well, that digital slides have got numerous advantages over optical slides and are more suitable in education.

    The aim of this research survey was to understand current global thinking around the need for and development of a paediatric biopharmaceutics classification system (pBCS) to be used for the development of paediatric medicines and regulatory purposes (e.g. Biowaivers). A literature review highlighted the paucity of data in this area and therefore a survey was developed to better understand this topic to identify areas of common thinking and highlight future research needs. Global experts in paediatric biopharmaceutics were identified from existing networks and public forums. An online survey was developed and circulated broadly to maximise participation. Sixty individuals (including academics, health care professionals, pharmaceutical industry scientists and regulators) completed the survey, bringing together their views on the need for a pBCS. The results highlighted that the area of greatest concern was the definition of BCS II and IV drugs within this population and additional research is required to generate evidence to underpin this issue. In questions relating to permeability and dissolution consensus was generally reached within the expert population suggesting that little additional research is required to define suitable criteria. More than 90% of those experts who participated agreed that a pBCS would be useful for paediatric populations with a greater need identified for the younger populations (newborn and infants compared to adolescents). The results presented will facilitate further discussion and research into the evidence to underpin a relevant pBCS. These results highlight the need for additional evidence and guidance in this area. Copyright © 2016. Published by Elsevier B.V.

  13. Rock Slide Risk Assessment: A Semi-Quantitative Approach

    , four of the slides caused formation of tsunami waves which washed up to 74 m above the lake level. Two of the slides resulted in many fatalities in the inner part of the Loen Valley as well as great damages. There are three predominant joint structures in Ramnefjell Mountain, which controls failure and the geometry of the slides. The first joint set is a foliation plane striking northeast-southwest and dipping 35˚ -40˚ to the east-southeast. The second and the third joint sets are almost perpendicular and parallel to the mountain side and scarp, respectively. These three joint sets form slices of rock columns with width ranging between 7-10 m and height of 400-450 m. It is stated that the joints in set II are opened between 1-2 m, which may bring about collection of water during heavy rainfall or snow melt causing the slices to be pressed out. It is estimated that water in the vertical joints both reduces the shear strength of sliding plane and causes reduction of normal stress on the sliding plane due to formation of uplift force. Hence rock slides in Ramnefjell mountain occur in plane failure mode. The quantitative evaluation of rock slide risk requires probabilistic analysis of rock slope stability and identification of consequences if the rock slide occurs. In this study failure probability of a rock slice is evaluated by first-order reliability method (FORM). Then in order to use the calculated probability of failure value (Pf) in risk analyses, it is required to associate this Pf with frequency based probabilities (i.ePf / year) since the computed failure probabilities is a measure of hazard and not a measure of risk unless they are associated with the consequences of the failure. This can be done by either considering the time dependent behavior of the basic variables in the probabilistic models or associating the computed Pf with frequency of the failures in the region. In this study, the frequency of previous rock slides in the previous century in

    Full Text Available The effectiveness and applicability of magnetic levitation systems need precise feedback control designs. A cascade control approach consisting of sliding mode control plus sliding mode control (SMC plus SMC is designed to solve position control problem and to provide a high control performance and robustness to the magnetic levitation plant. It is shown that the SMC plus SMC cascade controller is able to eliminate the effects of the inductance related uncertainties of the electromagnetic coil of the plant and achieve a robust and precise position control. Experimental and numerical results are provided to validate the effectiveness and feasibility of the method.

    2008-04-01

    Full Text Available In this paper, a fuzzy logic controller (FLC is designed, based on the similarity between the FLC and the sliding mode control (SMC, for a class of nonlinear system to tackle the nonlinear control problems with modelling uncertainties, plant parameters variations and external disturbances. The proposed scheme gives fast dynamic response with no overshoot and zero steady-state error. To show the validity and the effectiveness of the control method, simulations are performed for the speed control of a switched reluctance motor. The simulation results show that the controller designed is more effective than the conventional sliding mode controller in enhancing the robustness of control systems with high accuracy.

Overall, patients were relatively knowledgeable about depression and its occurrence in PD. However, many patients believed that depression is a normal reaction to the illness. While many respondents would be reluctant to initiate a discussion of depression during a clinical evaluation, most would feel comfortable talking about depression with their physician if he or she asked them questions about their mood. Based on the results of this survey, we recommend the following approach for physicians: (1 inform PD patients that, although a frequent occurrence, depression need not be accepted as a “normal reaction” to PD; and (2 routinely inquire about depressive symptoms rather than waiting for the patient to spontaneously report them.Keywords: depression, Parkinson’s disease, survey

    Full Text Available In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS evaluates students’ epistemology at the beginning and end of a semester. Students respond to paired questions about how they personally perceive doing experiments in laboratory courses and how they perceive an experimental physicist might respond regarding their research. Also, at the end of the semester, the E-CLASS assesses a third dimension of laboratory instruction, students’ reflections on their course’s expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for physics education research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results.

    In Hong Kong, nearly 1,300 women participated by telephone in the International Violence Against Women Survey in 2006. One in five respondents had experienced violence since age 16. Sexual violence (13.4%) was more frequent than physical violence (11.7%). Women were more likely to be abused by men they knew (13.5%) than by strangers (8%). Compared with other surveyed countries, Hong Kong recorded among the lowest rates of violence by both intimate partners and non-partners. These results suggest that cultural influences linked to the interaction of modernization and some protective factors found in the adherence to traditional Chinese values are relevant. © The Author(s) 2015.

    To describe health and nutrition status in the elderly population in Mexico. Information from 5,480 adults (>60 years) obtained by the National Health and Nutrition Survey (ENSANUT-2006) was analyzed. Frequencies, means, and confidence intervals at 95% were obtained and adjusted for design effect. Forty percent of the adults reported a lack of social security, 2% suffered from malnutrition, women were affected two times more than men by anemia (34.8 vs. 17%), more than 60% of the population were overweight and had obesity, approximately 25% suffered from hypertension according to the survey, and between 15 and 20% were diabetic. The results of this study show that health and nutrition status among the Mexican elderly population is inadequate. This is a situation that urgently needs to be addressed in order to improve the quality of life of older adults in Mexico.

    Based upon observations indicating decreasing attractiveness of groups within and outside the clinical field, the present study aimed to determine attitudes toward, and expectations of, groups in a representative sample of 2512 German citizens. The survey also included questions specifically related to group psychotherapy and its acceptance. In addition, psychological characteristics of respondents (measures of narcissism, psychological impairment, and emotion regulation) and socio-demographic variables were assessed to examine their potential association with group-related attitudes. In total, the survey revealed a relatively positive picture of attitudes and expectations toward groups in general and psychotherapy groups in particular. Those with more open attitudes towards groups were comparatively less distressed, anxious, and depressed; they favored emotional reappraisal instead of suppression as the dominant strategy to regulate their emotions. Contrary to prediction, narcissism did not influence attitudes towards groups. The results are related to current discussions of the attractiveness of groups and to implications for the practice of group psychotherapy.

    This research surveyed 170 school-based speech-language pathologists (SLPs) in one northeastern state, with only 1.8% reporting telepractice use in school-settings. These results were consistent with two ASHA surveys (2002; 2011) that reported limited use of telepractice for school-based speech-language pathology. In the present study, willingness to use telepractice was inversely related to age, perhaps because younger members of the profession are more accustomed to using technology. Overall, respondents were concerned about the validity of assessments administered via telepractice; whether clinicians can adequately establish rapport with clients via telepractice; and if therapy conducted via telepractice can be as effective as in-person speech-language therapy. Most respondents indicated the need to establish procedures and guidelines for school-based telepractice programs.

    An inquiry at German surgical departments about their bone bank techniques showed that 45% of clinical hospitals use allogeneic bone implants among other implants. In 1989, the year of the official survey, allogeneic bone was transplanted about 6000 times in these clinical hospitals. Despite of this high transplantation frequency important differences turn out regarding selection and testing of recipients, transplantation storage and treatment. A lot of clinical hospitals do not perform important donor examinations inspite of proven transmission risks of bacterial and viral diseases by deep frozen bone. A trend analysis shows that despite of the risk of an HIV-transmission and the resulting difficulties in the logistic of the bone bank, the transplantation frequency allogeneic bone stays constant. The official surveys prove the large range of bone bank techniques and should give rise to make efforts to take note of the recommendations for bone banking techniques.

    Strong gravitational lenses are valuable objects for studying galaxy structure and cosmology. Lensing is a unique probe of the dark matter structure of galaxies, groups, and clusters, as well as an independent tool for constraining cosmological parameters. Lensing also magnifies the background source population, allowing for detailed studies of their properties at high resolution. However, strong lenses are rare and difficult to find, requiring deep wide-area high-resolution imaging surveys. With data from the ongoing Hyper Suprime-Cam (HSC) Subaru Strategic Program, we have discovered over 100 new strong lenses at the galaxy and group scale to expand the sample of lensing systems, particularly at redshifts z > 0.5, where there have previously been relatively few known lenses. We present a summary of the latest strong lensing science results from the HSC survey data taken through the S17A semester.

    Wear intensity of the sliding electric contact steel 1020/steel 1045 depending on sliding time is presented at the contact current density higher than 100 A/cm2 without lubricant. It is shown that wear intensity of 1020 steel decreases at increasing of sliding time. Wear intensity is stabilized after some sliding time. This time (burn-in time) decreases at reduction of current density. Structural changes are realized in surface layer. Signs of liquid phase are observed on sliding surface. This liquid isn't a result of melting. It is established using Auger spectrometry that the contact layer contains up to 50 at.% of oxygen.

    The purpose of this survey was to assess the current practice in Europe regarding cryoablation for treatment of different cardiac arrhythmias. The data are based on an electronic questionnaire sent to members of the European Heart Rhythm Association Research Network. Responses were received from 49 centres in 18 countries. The results show that cryoablation for supraventricular tachycardia in European centres is an alternative to radiofrequency ablation, which is in accordance with guidelines. There is reasonable consensus regarding clinical results and complications of cryoablation procedure. Some inter-centre variability with respect to patient selection and ablation strategy in cryoablation of atrial fibrillation was demonstrated, underscoring the need for further research.

    To evaluate the external quality survey results of newborn hereditary deafness gene mutations to improve and enhance the testing quality of hereditary deafness gene mutations. Each of 30 voluntarily participating laboratories testing newborn hereditary deafness gene mutations received 15 lots of quality control blood spots in this survey at May 2013, including mitochondria DNA 12SrRNA 1555A>G (201311-201315), SLC26A4 IVS7-2A>G (201321-201325) and GJB2 235delC (201331-201335). The testing results, methods, equipments and reagent information were submitted for analyses of Clinet EQA, Microsoft Excel 2007 and SPSS 13.0. The rates of correction (number of correct results/total number of submitted results) were used for evaluating the performance of laboratories. Among them, 24 laboratories submitted the testing results of mitochondria DNA 12SrRNA 1555A>G and the rate of submission was 80.0% (24/30). The rates of correction for each lot were 95.8% (23/24), 95.8% (23/24), 100% (24/24), 95.8% (23/24) and 95.8% (23/24) respectively and the overall rate was 96.7% (116/120). And 23 laboratories submitted the other two kinds of genetic test results, the rate of submission was 76.7% (23/30); the rates of correction for each lot of SLC26A4 IVS7-2A>G genetic test were 95.7% (22/23), 95.7% (22/23), 100% (23/23), 95.7% (22/23) and 95.7% (22/23) respectively and the overall rate was 96.5% (111/115); the genetic test results of GJB2 235delC were all correct (23/23). In this survey, 2/3 laboratories employed fluorescent polymerase chain reaction (PCR) and the remainder microarray chips. The survey of newborn deafness gene mutation testing results is generally satisfactory. Only mitochondria DNA 12SrRNA and SLC26A4 have some errors. The laboratories of gene testing should improve their quality control system, correct mistakes during the test period without any delay and boost the rate of correction for newborn hereditary deafness gene testing.

    To obtain information on the demographics of Australian horse owners. An invitation to participate in an opt-in, internet-based survey was sent to 7000 persons who had registered an email address to receive information from the Australian Horse Industry Council Inc. These horse owners represented approximately 1.75% of the total horse owners in Australia. The survey was available for completion between 1 and 31 July 2009. There were 3377 (48%) useable responses. The respondents were a self-selected group of approximately 0.85% of the estimated total horse owners in Australia. The overall geographic distribution of respondents was the same as the general population at a state and territory level. In general, respondents were female and aged between 31 and 60 years; most lived in rural areas of Queensland, New South Wales or Victoria; had at least a secondary education, but no formal horse industry qualification; had a higher weekly income if based in a capital city; earned less than 10% of weekly income from horse-related activities; were a member of more than one horse industry organisation; reported an affiliation with one of more than 300 different horse industry organisations; spent 10-30% of their daily time with horses; and preferred to receive information by email. The responses from this survey of horse owners provided demographic information that was previously unavailable. Horse owners tended to be older than the general population, had a higher level of education attainment, were in higher weekly income brackets and lived mostly in non-metropolitan areas of Australia. Because of the self-selection and small sample size, the results need to be interpreted with caution. Nevertheless, the present results are compatible with other smaller random and non-random surveys of horse owners internationally. © 2015 Australian Veterinary Association.

    Background Eliciting cancer survivors’ priorities is essential to address the specific needs of cancer survivor subgroups. Objective To describe long-term rectal cancer survivors’ greatest challenges related to treatment. Design Observational study with cross-sectional survey. Setting Members of Kaiser Permanente, Northern California and Northwest health plans. Patients A survey was mailed to long-term (≥5 years post diagnosis) rectal cancer survivors who had an anastomosis, temporary ostomy, or permanent ostomy. Main Outcome Measures An open-ended question about the greatest challenge related to cancer surgery. We categorized responses using a grounded theory approach with double coding for reliability. Bonferroni-adjusted X2 values were used to assess differences in the proportions of subgroups who mentioned challenges within each response category. Results The survey completion rate was 61% (577/953); 76% (440/577) of participants responded to the greatest challenge question. Respondents’ greatest challenges were bowel/ostomy management (reported by 44%), negative psychosocial effects (37%), late effects of treatment (21%), comorbidities and aging (13%), postoperative recovery (5%), and negative health care experiences (5%). Survivors with temporary ostomy or anastomosis were more likely than survivors with permanent ostomy to report late effects (postomy to report negative psychosocial impacts (p=0.0001). Conclusions Our results reveal the need for bowel/ostomy management, psychosocial services and surveillance for late effects in survivorship and supportive care services for all rectal cancer survivors, regardless of ostomy status. The perspective of long-term survivors with anastomosis reveals challenges that may not be anticipated during treatment decision-making. Limitations Generalizability is restricted by the lack of ethnically and racially diverse, uninsured (non-Medicare-eligible population), and non-English-speaking participants. Because the

    -Previous studies suggest that training in pathology residency programs does not adequately prepare pathology residents to become competent in clinical chemistry. -To define the beliefs of pathology residents in the United States regarding their preparation for practicing clinical chemistry in their career, their attitude toward the discipline, and the attractiveness of clinical chemistry as a career. -The residents of all pathology residency programs in the United States were given the opportunity to participate in an online survey. -Three hundred thirty-six pathology residents responded to the survey. Analysis of the survey results indicates that pathology residents are more likely to believe that their income may be lower if they select a career that has a clinical chemistry focus and that their faculty do not value clinical chemistry as much as the anatomic pathology part of the residency. Residents also report that clinical chemistry is not as enjoyable as anatomic pathology rotations during residency or preferable as a sole career path. A large proportion of residents also believe that they will be slightly prepared or not prepared to practice clinical chemistry by the end of their residency and that they do not have enough background and/or time to learn clinical chemistry during their residency programs to be able to practice this specialty effectively post graduation. -Our survey results suggest that many pathology residents do not have a positive attitude toward clinical chemistry and do not experience a supportive learning environment with an expectation that they will become competent in clinical chemistry with a residency alone.

    Full Text Available Abstract Background An online consultation system using virtual slides (whole slide images; WSI has been developed for pathological diagnosis, and could help compensate for the shortage of pathologists, especially in the field of dermatopathology and in other fields dealing with difficult cases. This study focused on the performance and future potential of the system. Method In our system, histological specimens on slide glasses are digitalized by a virtual slide instrument, converted into web data, and up-loaded to an open server. Using our own purpose-built online system, we then input patient details such as age, gender, affected region, clinical data, past history and other related items. We next select up to ten consultants. Finally we send an e-mail to all consultants simultaneously through a single command. The consultant receives an e-mail containing an ID and password which is used to access the open server and inspect the images and other data associated with the case. The consultant makes a diagnosis, which is sent to us along with comments. Because this was a pilot study, we also conducted several questionnaires with consultants concerning the quality of images, operability, usability, and other issues. Results We solicited consultations for 36 cases, including cases of tumor, and involving one to eight consultants in the field of dermatopathology. No problems were noted concerning the images or the functioning of the system on the sender or receiver sides. The quickest diagnosis was received only 18 minutes after sending our data. This is much faster than in conventional consultation using glass slides. There were no major problems relating to the diagnosis, although there were some minor differences of opinion between consultants. The results of questionnaires answered by many consultants confirmed the usability of this system for pathological consultation. (16 out of 23 consultants. Conclusion We have developed a novel

    The tectonic uplift of South Portugal in the last 5 Million years (My) was firstly identified on the basis of morphologic criteria by Mariano Feio (1952, "The evolution of the relief of Baixo Alentejo and Algarve", transl.). However, the assessment of continental vertical movements off Portugal and its relation with tectonics was only initiated in the 1990-ies. This work was carried out in the framework of FP6 and FP7 in the domains of Natural Hazards funded by the European Community. The swath bathymetry cartography of the southwest part of the Iberian Peninsula resulted from the effort of European and national projects, of 19 oceanographic surveys, a total of 200 ship time days executed from 2000 to 2006, involving 14 research institutions from 7 European countries. As a result of this effort together with acquisition and interpretation of thousands of km of seismic reflection profiles, the Pliocene-Quaternary uplift of the Alentejo continental margin (SW Portugal) is now widely accepted by the scientific community. This uplift has not been yet quantified but it is possible that can have contributed to erosion and deposition of metallic ores as placers in the continental shelf. This argues in favor of the potential existence of placers in the continental shelf and the need for the detailed investigation that will allow determination of ideal location for placers deposition in the past Pliocene-Quaternary (5 My). The source for metals can arguably be associated to the Iberian Pyrite Belt ores hosted in the Alentejo Paleozoic formations and to the hyper-alkaline intrusions of Sines and Monchique of Late Cretaceous age. Artificial renourishment of beaches with offshore sand has not been assessed for the Alentejo littoral, despite that the coast located to the south of the Sines segment shows high susceptibility to erosion. This has been observed on a regular basis as the beaches are frequently devoid of sand, thus jeopardizing their touristic potential. The detailed

    The demand for hair and tattoo removal with laser and IPL technology (intense pulsed light technology) is continually increasing. Nowadays these treatments are often carried out by medical laypersons without medical supervision in franchise companies, wellness facilities, cosmetic institutes and hair or tattoo studios. This is the first survey is to document and discuss this issue and its effects on public health. Fifty patients affected by treatment errors caused by medical laypersons with laser and IPL applications were evaluated in this retrospective study. We used a standardized questionnaire with accompanying photographic documentation. Among the reports there were some missing or no longer traceable parameters, which is why 7 cases could not be evaluated. The following complications occurred, with possible multiple answers: 81.4% pigmentation changes, 25.6% scars, 14% textural changes and 4.6% incorrect information. The sources of error (multiple answers possible) were the following: 62.8% excessively high energy, 39.5% wrong device for the indication, 20.9% treatment of patients with darker skin or marked tanning, 7% no cooling, and 4.6% incorrect information. The causes of malpractice suggest insufficient training, inadequate diagnostic abilities, and promising unrealistic results. Direct supervision by a medical specialist, comprehensive experience in laser therapy, and compliance with quality guidelines are prerequisites for safe laser and IPL treatments. Legal measures to make such changes mandatory are urgently needed. © The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

    2017-03-01

    Presentations using slide software such as PowerPoint are widely performed in offices and schools. The improvement of presentation skills among ordinary people is required because these days such an opportunity of giving presentation is becoming so common. One of the key factors for making successful presentation is the visibility of the slides, as well as the contents themselves. We propose an algorithm to numerically evaluate the visibility of presentation slides. Our method receives a presentation as a set of images and eliminates the background from the slides to extract characters and figures. This algorithm then evaluates the visibility according to the number and size of characters, their colors, and figure layouts. The slide evaluation criteria are based on the series of experiments with 20 participants to parameterize typical values for visual elements in slides. The algorithm is implemented on an iMac and takes 0.5 sec. to evaluate a slide image. The evaluation score is given as a value between 0 and 100 and the users can improve their slide pages with lower scores. Our future work includes a series of experiments with various presentations and extending our method to publish as a web-based rating service for learning presentation skills.

    : The purpose of this study was to examine the current management of the enteral feeding regimens of premature infants cared for in the neonatal intensive care unit (NICU). : The study included responses from 70 neonatal nurses who participated in a 2009 Neonatal Enteral Feeding Survey distributed electronically to the National Association of Neonatal Nurses membership. These respondents were representative of both the United States and Canada, with 29 US states represented. The majority of respondents (95.7%) reported current nursing employment in a level III NICU. : Survey research was used in this exploratory study. The survey, Enteral Tube Feeding Practices in the Neonatal Intensive Care Unit, was developed in collaboration with expert neonatal nurses and nutritionists, pilot tested, and distributed via electronic means. : Survey research was conducted according to the Dillman methodology. Data analysis included descriptive statistics and univariate analysis of variance assessing for significant differences in specific neonatal feeding practices reported. Thematic analysis was used to analyze the qualitative data reported. : The outcome measures included the survey responses to the questions asked about the implementation of an enteral feeding protocol and various aspects of enteral feeding practices in the NICU. : The majority of participants (60.9%) reported that an enteral feeding protocol was implemented in practice, but that it was inconsistently followed because of individual physician or nurse practice patterns, or highly individualized feeding plans required of specific clinical care needs of the patient. Respondents indicated that gestational age was the leading criteria used to initiate feedings, and patent ductus arteriosis treatment was the primary contraindication to enteral feedings. The leading factor reported to delay or alter enteral feedings was the presence of gastric residuals. Survey data indicated that other contraindicating factors to

    Background: The 1996 Guidelines for Preparation of Sterile Products in Pharmacies of the Canadian Society of Hospital Pharmacists (CSHP) represent the current standard of practice for sterile compounding in Canada. However, these guidelines are practice recommendations, not enforceable standards. Previous surveys of sterile compounding practices have shown that actual practice deviates markedly from voluntary practice recommendations. In 2004, the United States Pharmacopeia (USP) published its “General Chapter Pharmaceutical Compounding—Sterile Preparations”, which set a more rigorous and enforceable standard for sterile compounding in the United States. Objectives: To assess sterile compounding practices in Canadian hospital pharmacies and to compare them with current CSHP recommendations and USP chapter standards. Methods: An online survey, based on previous studies of sterile compounding practices, the CSHP guidelines, and the chapter standards, was created and distributed to 193 Canadian hospital pharmacies. Results: A total of 133 pharmacies completed at least part of the survey, for a response rate of 68.9%. All respondents reported the preparation of sterile products. Various degrees of deviation from the practice recommendations were noted for virtually all areas of the CSHP guidelines and the USP standards. Low levels of compliance were most notable in the areas of facilities and equipment, process validation, and product testing. Availability in the central pharmacy of a clean room facility meeting or exceeding the criteria of International Organization for Standardization (ISO) class 8 is a requirement of the chapter standards, but more than 40% of responding pharmacies reported that they did not have such a facility. Higher levels of compliance were noted for policies and procedures, garbing requirements, aseptic technique, and handling of hazardous products.

    The Palomar Transient Factory (PTF) is a new fully-automated, wide-field survey conducting a systematic exploration of the optical transient sky. The transient survey is performed using a new 8.1 square degree, 101 megapixel camera installed on the 48-inch Samuel Oschin Telescope at Palomar Observatory. The PTF Camera achieved first light at the end of 2008, completed commissioning in July 2009, and is now in routine science operations. The camera is based on the CFH12K camera, and was extensively modified for use on the 48-inch telescope. A field-flattening curved window was installed, the cooling system was re-engineered and upgraded to closed-cycle, custom shutter and filter exchanger mechanisms were added, new custom control software was written, and many other modifications were made. We here describe the performance of these new systems during the first year of Palomar Transient Factory operations, including a detailed and long term on-sky performance characterization. We also describe lessons learned during the construction and commissioning of the upgraded camera, the photometric and astrometric precision currently achieved with the PTF camera, and briefly summarize the first supernova results from the PTF survey.

    Rural areas of the United States are uniquely vulnerable to the impacts of natural disasters. One possible way to mitigate vulnerability to disasters in rural communities is to have a high-quality hazard mitigation plan in place. To understand the resources available for hazard mitigation planning and determine how well hazard mitigation plans in rural counties meet the needs of vulnerable populations, we surveyed the lead planning or emergency management official responsible for hazard mitigation plans in 96 rural counties in eight states in the Southeastern United States. In most counties, emergency management was responsible for implementing the county's hazard mitigation plan and the majority of counties had experienced a presidentially declared disaster in the last 5 years. Our research findings demonstrated that there were differences in subjective measures of vulnerability (as reported by survey respondents) and objective measures of vulnerability (as determined by US Census data). In addition, although few counties surveyed included outreach to vulnerable groups as a part of their hazard mitigation planning process, a majority felt that their hazard mitigation plan addressed the needs of vulnerable populations "well" or "very well." These differences could result in increased vulnerabilities in rural areas, particularly for certain vulnerable groups.

    We aimed to determine availability of core Hospital Information Systems (HIS) functions implemented in Turkish hospitals and the perceived importance of these functions on quality and patient safety. We surveyed quality directors (QDs) at civilian hospitals in the nation of Turkey. Data were collected via web survey using an instrument with 50 items describing core functionality of HIS. We calculated mean availability of each function, mean and median values of perceived impact on quality, and we investigated the relationship between availability and perceived importance. We received responses from 31% of eligible institutions, representing all major geographic regions of Turkey. Mean availability of 50 HIS functions was 65.6%, ranging from 19.6% to 97.4%. Mean importance score was 7.87 (on a 9-point scale) ranging from 7.13 to 8.41. Functions related to result management (89.3%) and decision support systems (52.2%) had the highest and lowest reported availability respectively. Availability and perceived importance were moderately correlated (r = 0.52). QDs report high importance of the HIS functions surveyed as they relate to quality and patient safety. Availability and perceived importance of HIS functions are generally correlated, with some interesting exceptions. These findings may inform future investments and guide policy changes within the Turkish healthcare system. Financial incentives, regulations around certified HIS, revisions to accreditation manuals, and training interventions are all policies which will help integrate HIS functions to support quality and patient safety in Turkish hospitals.

    Full Text Available In July of 1931, on the eve of International Polar Year II, an Arctic flight of the Graf Zeppelin rigid airship was organized. This flight was a realization of the idea of F. Nansen, who advocated the use of airships for the scientific exploration of the Arctic territories, which were poorly studied and hardly accessible at that time. The route of the airship flight was Berlin – Leningrad – Arkhangelsk – Franz Josef Land – Severnaya Zemlya – the Taimyr Peninsula – Novaya Zemlya – Arkhangelsk – Berlin. One of scientific goals of the expedition was to measure the H and D geomagnetic field components. Actually, the first aeromagnetic survey was carried out in the Arctic during the flight. After the expedition, only preliminary results of the geomagnetic measurements, in which an anomalous behavior of magnetic declination in the high-latitude part of the route was noted, were published. Our paper is concerned with the first aeromagnetic measurements in the Arctic and their analysis based on archival and modern data on the magnetic field in the Barents and Kara sea regions. It is shown that the magnetic field along the flight route had a complicated structure, which was not reflected in the magnetic charts of those times. The flight was very important for future development of aero- and ground-based magnetic surveys in the Arctic, showing new methods in such surveys.

    2012-02-03

    BACKGROUND AND OBJECTIVE: Adverse effects associated with difficult airway management can be catastrophic and include death, brain injury and myocardial injury. Closed-malpractice claims have shown prolonged and persistent attempts at endotracheal intubation to be the most common situation leading to disastrous respiratory events. To date, there has been no evaluation of the types of difficult airway equipment currently available in Irish departments of emergency medicine. The objective of this survey was to identify the difficult airway equipment available in Irish departments of emergency medicine. METHODS: Departments of emergency medicine in the Republic of Ireland with at least one dedicated Emergency Medicine consultant were surveyed via telephone. RESULTS: All of the departments contacted held at least one alternative device on site for both ventilation and intubation. The most common alternative ventilation device was the laryngeal mask airway (89%). The most common alternative intubating device was the surgical airway device (100%). CONCLUSIONS: Irish departments of emergency medicine compare well with those in the UK and USA, when surveyed concerning difficult airway equipment. However, we believe that this situation could be further improved by training inexperienced healthcare providers in the use of the laryngeal mask airway and intubating laryngeal mask airway, by placing greater emphasis on the ready availability of capnography and by the increased use of portable difficult airway storage units.

    To present estimations obtained from a population-level survey conducted in Mexico of prevalence rates of mono-, poly- and multidrug-resistant strains among newly diagnosed cases of pulmonary tuberculosis (TB), as well as the main factors associated with multidrug resistance (combined resistance to isoniazid and rifampicin). Study data came from the National Survey on TB Drug Resistance (ENTB-2008), a nationally representative survey conducted during 2008-2009 in nine states with a stratified cluster sampling design. Samples were obtained for all newly diagnosed cases of pulmonary TB in selected sites. Drug susceptibility testing (DST) was performed for anti-tuberculosis drugs. DST results were obtained for 75% of the cases. Of these, 82.2% (95%CI 79.5-84.7) were susceptible to all drugs. The prevalence of multidrug-resistant TB (MDR-TB) was estimated at 2.8% (95%CI 1.9-4.0). MDR-TB was associated with previous treatment (OR 3.3, 95%CI 1.1-9.4). The prevalence of drug resistance is relatively low in Mexico. ENTB-2008 can be used as a baseline for future follow-up of drug resistance.

    Food safety and food defense are both responsibilities of public health agencies. Food safety practices within restaurants are regulated by state and local public health laws based on the US Food and Drug Administration Model Food Code. However, little is known about preemptive practices against intentional food-borne outbreaks within restaurants. The researchers administered a survey to a 50 percent random sample of South Carolina's restaurants, a state that relies heavily on tourism and the restaurant industry for its economic well-being. The survey received a response rate of 15 percent. The food defense practice items fall under three functional categories: employee management and training practices; vendor and delivery-related practices; and physical facilities and operational security practices. This study presents the results, classified by geographic region. Findings indicate some key areas of vulnerability that need attention to protect the public from mass food outbreaks due to intentional contamination. Of concern, there is much variation in practices by geographic region. On the basis of the survey, recommendations are made to improve restaurant preparedness against food-borne outbreaks from terrorism and malevolent contamination.

    It was the aim of this work to assess and track the workload, working conditions and professional recognition of radiation oncology medical physicists (ROMPs) in the Asia Pacific region over time. In this third survey since 2008, a structured questionnaire was mailed in 2014 to 22 senior medical physicists representing 23 countries. As in previous surveys the questionnaire covered seven themes: 1 education, training and professional certification, 2 staffing, 3 typical tasks, 4 professional organisations, 5 resources, 6 research and teaching, and 7 job satisfaction. The response rate of 100% is a result of performing a survey through a network, which allows easy follow-up. The replies cover 4841 ROMPs in 23 countries. Compared to 2008, the number of medical physicists in many countries has doubled. However, the number of experienced ROMPs compared to the overall workforce is still small, especially in low and middle income countries. The increase in staff is matched by a similar increase in the number of treatment units over the years. Furthermore, the number of countries using complex techniques (IMRT, IGRT) or installing high end equipment (tomotherapy, robotic linear accelerators) is increasing. Overall, ROMPs still feel generally overworked and the professional recognition, while varying widely, appears to be improving only slightly. Radiation oncology medical physics practice has not changed significantly over the last 6 years in the Asia Pacific Region even if the number of physicists and the number and complexity of treatment techniques and technologies have increased dramatically.

    Andritzky, Walter

    2003-12-01

    In the last decade, increasing divorce rates, a joint custodial concept, and a deficient legal situation of non-married fathers have been involuntarily provoking cases of a parent with child custody alienating that child in order to exclude the other parent from visitations and educational participation. Medical certificates are frequently of fateful importance in child custody litigation. In an mail survey conduced in six German cities, N = 133 child psychiatrists were asked about the frequency in which they issue such certificates, what certificates contained, what recommendations were made, and where possible the reasons why the other parent was not included in the diagnostic process. According to the results 74.4% of those surveyed were asked to issue such medical certificates at least once in the year prior to the survey; 42% of the psychiatrists stating that the other parent never or only sometimes participated. The symptoms most frequently certified were behavioural disorders (46%), aggression (34%), problems in school/ADD (28%), anxiety (26%), bed-wetting (23%), depression (21%), and psychosomatic reactions (20%). Outlining the characteristics of alienated children and of alienating parents, of "natural" and of "induced" stress-symptoms in children after parental separation, the article provides physicians and institutions of the health system with support to prevent medical certificates being abused in child custody litigation. Some fundamental guidelines are presented as to what aspects and should be explored and which persons referred to before certificates are issued to parents, social workers or judges of family law courts.

    Congenital cytomegalovirus (CMV) is as common a cause of serious disability as Down syndrome and neural tube defects. When acquired prior to or during pregnancy, CMV can be transmitted transplacentally to the fetus, sometimes causing serious temporary symptoms, permanent disabilities, or both to the child. One way to prevent infection before and during pregnancy is through simple hygienic practices, such as handwashing. This study used the 2005 annual HealthStyles survey, a mail survey of the U.S. population aged women who reported they had heard of CMV, the largest proportion said they had heard about it from a doctor, hospital, clinic, or other health professional (29%). The accuracy of women's knowledge of what conditions congenital CMV can cause in the fetus was limited. The prevention behaviors surveyed in the present study (i.e., handwashing, not sharing drinking glasses or eating utensils with young children, and not kissing young children on the mouth) appeared to be generally acceptable. There are prevention behaviors that have the potential of substantially reducing the occurrence of CMV-related permanent disability in children. However, our results suggest that few women are aware of CMV or these prevention behaviors.

    The slitless spectrometer plays an important role in the Wide-Field InfraRed Survey Telescope (WFIRST) mission for the survey of emission-line galaxies. This will be an unprecedented very wide field, HST quality 3D survey of emission line galaxies. The concept of the compound grism as a slitless spectrometer has been presented previously. The presentation briefly discusses the challenges and solutions of the optical design, and recent specification updates, as well as a brief comparison between the prototype and the latest design. However, the emphasis of this paper is the progress of the grism prototype: the fabrication and test of the complicated diffractive optical elements and powered prism, as well as grism assembly alignment and testing. Especially how to use different tools and methods, such as IR phase shift and wavelength shift interferometry, to complete the element and assembly tests. The paper also presents very encouraging results from recent element tests to assembly tests. Finally we briefly touch the path forward plan to test the spectral characteristic, such as spectral resolution and response.

    Full Text Available Background. The aim of this survey was to describe, in a situation of growing availability of monitoring devices and parameters, the practices in haemodynamic monitoring at the bedside. Methods. We conducted a Web-based survey in Swiss adult ICUs (2009-2010. The questionnaire explored the kind of monitoring used and how the fluid management was addressed. Results. Our survey included 71% of Swiss ICUs. Echocardiography (95%, pulmonary artery catheter (PAC: 85%, and transpulmonary thermodilution (TPTD (82% were the most commonly used. TPTD and PAC were frequently both available, although TPTD was the preferred technique. Echocardiography was widely available (95% but seems to be rarely performed by intensivists themselves. Guidelines for the management of fluid infusion were available in 45% of ICUs. For the prediction of fluid responsiveness, intensivists rely preferentially on dynamic indices or echocardiographic parameters, but static parameters, such as central venous pressure or pulmonary artery occlusion pressure, were still used. Conclusions. In most Swiss ICUs, multiple haemodynamic monitoring devices are available, although TPTD is most commonly used. Despite the usefulness of echocardiography and its large availability, it is not widely performed by Swiss intensivists themselves. Regarding fluid management, several parameters are used without a clear consensus for the optimal method.

    Background: Bioethics consultations are conducted in varied settings, including hospitals, universities, and other research institutions, but there is sparse information about bioethics consultations conducted in corporate settings such as pharmaceutical companies. The purpose of this article is to describe a bioethics consultation service at a pharmaceutical company, to report characteristics of consultations completed by the service over a 6-year period, and to share results of a consultation feedback survey. Methods: Data on the descriptive characteristics of bioethics consultations were collected from 2008 to 2013 and analyzed in Excel 2007. Categorical data were analyzed via the pivot table function, and time-based variables were analyzed via formulas. The feedback survey was administered to consultation requesters from 2009 to 2012 and also analyzed in Excel 2007. Results: Over the 6-year period, 189 bioethics consultations were conducted. The number of consultations increased from five per year in 2008 to approximately one per week in 2013. During this time, the format of the consultation service was changed from a committee-only approach to a tiered approach (tailored to the needs of the case). The five most frequent topics were informed consent, early termination of a clinical trial, benefits and risks, human biological samples, and patient rights. The feedback survey results suggest the consultation service is well regarded overall and viewed as approachable, helpful, and responsive. Conclusions: Pharmaceutical bioethics consultation is a unique category of bioethics consultation that primarily focuses on pharmaceutical research and development but also touches on aspects of clinical ethics, business ethics, and organizational ethics. Results indicate there is a demand for a tiered bioethics consultation service within this pharmaceutical company and that advice was valued. This company's experience indicates that a bioethics consultation service raises

  15. A double-layer hydrological model dedicated to glacier sliding

    Field observations show that subglacial hydrology and glacier dynamics are tightly linked. The basal friction law that controls sliding velocities via subglacial water-pressure has been developed but, unfortunately, subglacial water pressure cannot be easily assessed. In the existing physically-based hydrological models, the effective pressure is even set to zero, which prevents from using these models to accurately compute the basal water pressure. In the proposed approach, the water pressure is computed from Darcy's equations for a confined aquifer. These equations are applied to two different layers. The first one features a classical sediment drainage system. The second one, with an appropriate equivalent conductivity, consist of an efficient channel-type drainage system. This second layer is activated when the effective pressure tends toward zero and allows the drainage of the excess of water from the sediment layer. This hydrological model is coupled with a full Stokes ice flow model including a water-pressure dependant friction law used to compute the basal boundary condition. This modelling attempt is first carried out over a synthetic bedrock which is consistent with the specific characteristics of an Antarctic test outlet glacier. These characteristics result from a preliminary survey carried out during the 2007-2009 field seasons on the Astrolabe glacier (Terre Adélie French sector) in the framework of the DACOTA programme.

    We introduce and provide the scientific motivation for a wide-field photometric and spectroscopic chemodynamical survey of nearby early-type galaxies (ETGs) and their globular cluster (GC) systems. The SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey is being carried out primarily with Subaru/Suprime-Cam and Keck/DEIMOS. The former provides deep gri imaging over a 900 arcmin{sup 2} field-of-view to characterize GC and host galaxy colors and spatial distributions, and to identify spectroscopic targets. The NIR Ca II triplet provides GC line-of-sight velocities and metallicities out to typically ∼8 R {sub e}, and to ∼15 R {sub e} in some cases. New techniques to extract integrated stellar kinematics and metallicities to large radii (∼2-3 R {sub e}) are used in concert with GC data to create two-dimensional (2D) velocity and metallicity maps for comparison with simulations of galaxy formation. The advantages of SLUGGS compared with other, complementary, 2D-chemodynamical surveys are its superior velocity resolution, radial extent, and multiple halo tracers. We describe the sample of 25 nearby ETGs, the selection criteria for galaxies and GCs, the observing strategies, the data reduction techniques, and modeling methods. The survey observations are nearly complete and more than 30 papers have so far been published using SLUGGS data. Here we summarize some initial results, including signatures of two-phase galaxy assembly, evidence for GC metallicity bimodality, and a novel framework for the formation of extended star clusters and ultracompact dwarfs. An integrated overview of current chemodynamical constraints on GC systems points to separate, in situ formation modes at high redshifts for metal-poor and metal-rich GCs.

  17. The Mission Accessible Near-Earth Objects Survey (MANOS): photometric results

    The Mission Accessible Near-Earth Object Survey (MANOS) is a physical characterization survey of Near-Earth Objects (NEOs) to provide physical data for several hundred mission accessible NEOs across visible and near-infrared wavelengths. Using a variety of 1-m to 8-m class telescopes, we observe 5 to 10 newly discovered sub-km NEOs per month in order to derive their rotational properties and taxonomic class.Rotational data can provide useful information about physical properties, like shape, surface heterogeneity/homogeneity, density, internal structure, and internal cohesion. Here, we present results of the MANOS photometric survey for more than 200 NEOs. We report lightcurves from our first three years of observing and show objects with rotational periods from a couple of hours down to a few seconds. MANOS found the three fastest rotators known to date with rotational periods below 20s. A physical interpretation of these ultra-rapid rotators is that they are bound through a combination of cohesive and/or tensile strength rather than gravity. Therefore, these objects are important to understand the internal structure of NEOs. Rotational properties are used for statistical study to constrain overall properties of the NEO population. We also study rotational properties according to size, and dynamical class. Finally, we report a sample of NEOs that are fully characterized (lightcurve and visible spectra) as the most suitable candidates for a future robotic or human mission. Viable mission targets are objects with a rotational period >1h, and a delta-v lower than 12 km/s. Assuming the MANOS rate of object characterization, and the current NEO population estimates by Tricarico (2016), and by Harris and D'Abramo (2015), 10,000 to 1,000,000 NEOs with diameters between 10m and 1km are expected to be mission accessible. We acknowledge funding support from NASA NEOO grant number NNX14AN82G, and NOAO survey program.

  18. Epidural analgesia practices for labour: results of a 2005 national survey in Ireland.

    Fanning, Rebecca A

    2012-02-01

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    Background Oncology pharmacists are capable of providing medication therapy management (MTM) because of their level of training, practice experiences, and responsibilities. Very little data exist about their current practice, including changing roles in the multidisciplinary team, overall impact, and effects in the education of patients and healthcare professionals. Methods A 70-item survey about oncology pharmacists' activities in oral chemotherapy programs, MTM, and collaborative practice agreements (CPAs) was deployed using a web survey tool (Qualtrics, Provo, UT, USA), targeting pharmacist members of American College of Clinical Pharmacy (ACCP) Hematology/Oncology Practice and Research Network (PRN). The objective of this study was to determine oncology pharmacists' activities in areas of oral chemotherapy programs, MTM, and CPAs. A cross-sectional survey was distributed to the ACCP Hematology/Oncology PRN membership. Investigational Review Board approval was obtained. Results Of the 795 members who were sent the survey, 81 members (10%) responded; 33 respondents (47%) are involved with an oral chemotherapy program; with 42% measuring outcomes of programs. Only six pharmacists (19%) have published or presented their data. A total of 28 (35%) respondents provide MTM services, with almost half (43%) of these MTM services being dictated by CPAs. A small fraction of these pharmacists (21.4%) reported conducting quality assurance evaluations of their MTM services and three pharmacists (10.7%) reported publishing their results. Those pharmacists practicing under CPAs ( n = 28) were surveyed as to activities included in their CPA. The most common activities included adjusting medication, ordering, interpreting, and monitoring lab tests, developing therapeutic plans and educating patients. Reimbursement for providing these services was uncommon: MTM (4%), oral chemotherapy program (6%), and CPA services (11%). Reported obstacles to reimbursement included lack of

    The authors developed a survey and administered it to members of the American Dental Association (ADA) to elicit their views on leadership in dentistry, as well as to explore their leadership-related values and evaluation of their effectiveness as leaders, their experiences with leadership-related activities and perceptions of barriers to being a leader. The authors also examined how male and female dentists differed in their leadership-related responses. The authors collected survey data from 593 ADA members (mean age, 51 years; standard deviation, 10.75 years). Seventy-seven percent of respondents were male and 85 percent were European American. The most frequently reported aspects of leadership were leadership in one's own practice (31 percent), in the profession (26 percent), in the community (14 percent) and in dental organizations (9 percent). The most valued aspects of leadership were being a good leader in one's own practice (mean rating = 4.64 on a five-point scale, with 5 = very important) and having patients perceive them as leaders (mean rating = 4.38). The most frequent past leadership experiences were related to leadership in dental organizations (47 percent), and the most frequent current activities were related to leadership activities in the community (40 percent). Time constraints (46 percent) and family obligations (20 percent) were the biggest barriers to taking on more of a leadership role. According to the survey results, female respondents valued the importance of leadership more highly than did male respondents. The results of this survey show that dentists perceive professional leadership as closely related to leadership in their own dental practices and value this type of leadership most highly. However, about 40 percent of respondents reported that they engaged in current leadership activities in their communities, and 32 percent reported doing so in professional organizations. Practical Implications. ADA members who responded to this

    ORAU conducted confirmatory surveys of the Hematite site during the period of June 12 through June 13, 2012. The survey activities included in-process inspections, document review, walkover surveys, sampling activities, and laboratory analysis of split samples. WEC was forthcoming with information relating to practices, procedures, and surface scan results. Scans performed by the WEC technician were extremely thorough and methodical. The WEC and ORAU technicians identified the same areas of elevated activity with comparable detector responses. WEC sampling of re-use soils, waste soils, sediments, and groundwater were conducted under ORAU observation. The sampling efforts observed by ORAU were performed in accordance with site-specific procedures and in a manner sufficient to provide quality supporting data. Three observations were made during groundwater sampling activities. First, the water level indicator was re-used without submitting rinse blank. Second, bubbles created during tubing extraction could indicate the presence of volatilized organic compounds. Third, samplers did not use a photo ionization detector prior to sample collection to indicate the presence of volatile organic vapors. Results of split samples indicated a high level of comparability between the WEC and ORAU/ORISE radiological laboratories. Analytical practices and procedures appear to be sufficient in providing quality radiochemical data. All concentrations from the Soil Re-Use Area and sediment samples are below Uniform radionuclide-specific derived concentration guideline level (DCGL{sub W}) limits; thus, comparisons to the less conservative stratified geometry were not required. Results were compared to individual DCGLs and using the sum of fractions approach. Both composite soil samples collected from the Waste Handling Area (Bins 1 and 4) were well below the prescribed USEI waste acceptance criteria.

    Aims: We present results of a polarimetric survey of main-belt asteroids at Complejo Astronómico El Leoncito (Casleo), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry, to estimate diversity in polarimetric properties of asteroids that belong to different taxonomic classes, and to search for objects that exhibit anomalous polarimetric properties. Methods: The data were obtained with the Torino and CASPROF polarimeters at the 2.15 m telescope. The Torino polarimeter is an instrument that allows the simultaneous measurement of polarization in five different bands, and the CASPROF polarimeter is a two-hole aperture polarimeter with rapid modulation. Results: The survey began in 2003, and up to 2009 data of a sample of more than 170 asteroids were obtained. In this paper the results for 33 X-type objects are presented, several of them are being polarimetrically observed for the first time. Using these data we found polarization curves and polarimetric parameters for different groups among this taxonomic class and that there are objects with very different albedo in the sub-classes of the X taxonomic complex. Based on observations carried out at the Complejo Astronómico El Leoncito, operated under agreement between the Consejo Nacional de Investigaciones Científicas y Técnicas de la República Argentina and the National Universities of La Plata, Córdoba, and San Juan.Table 1 is only available at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/542/A11

    We present an overview and first results of the Stratospheric Observatory For Infrared Astronomy Massive (SOMA) Star Formation Survey, which is using the FORCAST instrument to image massive protostars from ˜10 to 40 μm. These wavelengths trace thermal emission from warm dust, which in Core Accretion models mainly emerges from the inner regions of protostellar outflow cavities. Dust in dense core envelopes also imprints characteristic extinction patterns at these wavelengths, causing intensity peaks to shift along the outflow axis and profiles to become more symmetric at longer wavelengths. We present observational results for the first eight protostars in the survey, I.e., multiwavelength images, including some ancillary ground-based mid-infrared (MIR) observations and archival Spitzer and Herschel data. These images generally show extended MIR/FIR emission along directions consistent with those of known outflows and with shorter wavelength peak flux positions displaced from the protostar along the blueshifted, near-facing sides, thus confirming qualitative predictions of Core Accretion models. We then compile spectral energy distributions and use these to derive protostellar properties by fitting theoretical radiative transfer models. Zhang and Tan models, based on the Turbulent Core Model of McKee and Tan, imply the sources have protostellar masses m * ˜ 10-50 M ⊙ accreting at ˜10-4-10-3 M ⊙ yr-1 inside cores of initial masses M c ˜ 30-500 M ⊙ embedded in clumps with mass surface densities Σcl ˜ 0.1-3 g cm-2. Fitting the Robitaille et al. models typically leads to slightly higher protostellar masses, but with disk accretion rates ˜100× smaller. We discuss reasons for these differences and overall implications of these first survey results for massive star formation theories.

    Development of engineer's “Human Performance” is being required to respond to various changes. “Human Performace” is defined as an ability of putting own knowledge and skill to a practical issue. Current engineering undergraduate education promotes to learn this ability. To examine effectiveness of the educational program, a questionnaire consisting of 66 items was developed and the survey was conducted across eight universities. As results, most students recognize importance of the ability, but their achievement is lower for English communication skill and adaptation of cultural difference. They learned the ability on laboratory experience for their thesis, experiment class, club activities, part-time jobs and other activities.

    Full Text Available The friction and wear properties of polyamide 6 (PA6 and poly-Acrylonitrile Butadiene Styrene (ABS sliding against metal under dry sliding, water absorption and electroplated (EP conditions were studied by using a pin-ondisc tribometer. The effect of applied load and sliding speed on the tribological behaviours of the polymer–metal sliding combinations under dry sliding, water absorbed and EP conditions were also investigated. The worn surfaces were examined by using Scanning Electron Microscope (SEM. Experimental results showed that ABS samples under water absorbed conditions showed higher wear loss compared to normal samples and the EP samples had exhibited lower wear loss compared to the water absorbed samples. Similarly EP-PA6 samples exhibited excellent wear resistance when compared with EP-ABS samples. Further, it was observed that the frictional heat produced on account of sliding action had a significant effect on the tribological behaviours of samples under dry sliding and water absorbed conditions.

    Full Text Available The concept of supply chain management has been evolving at a rapid pace in economic practice as wellas in scientific research, mainly in the field of logistics and supply chains. It also constitutes a reference point for researchers specializing in accounting, especially in management accounting. As a result, in recent years there has been an increasing number of publications on this research in the world, including in Poland. So far, however, there is a lack of publications that would present comprehensively the aspects of management accounting in the context of supply chain management. Therefore, this article has the following research objective: identification of the degree of development of management accounting, in research and practice, for the purposes of supply chain management. As research methods were used:review of the content of scientific articles and surveys conducted among companies in Poland. The results of survey study and literature review revealed that the most frequently addressed issues in business and in theory include cost management and performance measurement using financial indicators. In the case of other issues addressed in the publications there are discrepancies between theory and business practice. In effect, this means the need to improve the communication and integration of these two dimensions in the context of implementation of management accounting tools and methods for supply chain management support. The results presented in the article could be the basis for further, in-depth research in this area.

    To evaluate the effect of nonresponse bias on reports of the quality of end-of-life care that older adults receive. Nationwide retrospective survey of end-of-life care. Sixty-two Veterans Affairs Medical Centers. Patients were eligible if they died in a participating facility. One family member per patient was selected from medical records and invited to participate. The telephone survey included 14 items describing important aspects of the patient's care in the last month of life. Scores (0-100) reflect the percentage of items for which the family member reported that the patient received the best possible care, and a global item defined the proportion of families who said the patient received "excellent" care. To examine the effect of nonresponse bias, a model was created to predict the likelihood of response based on patient and family characteristics; then this model was used to apply weights that were equivalent to the inverse of the probability of response for that individual. Interviews were completed with family members of 3,897 of 7,110 patients (55%). Once results were weighted to account for nonresponse bias, the change in mean individual scores was 2% of families reporting "excellent" care. Of the 62 facilities in the sample, the scores of only 19 facilities (31%) changed more than 1% in either direction, and only 10 (16%) changed more than 2%. Although nonresponse bias is a theoretical concern, it does not appear to have a significant effect on the facility-level results of this retrospective family survey. © 2010, Copyright the Authors.

    Study Objectives: To estimate the prevalence and associations of broadly defined (i.e., meeting full ICD-10, DSM-IV, or RDC/ICSD-2 inclusion criteria) insomnia with work performance net of comorbid conditions in the America Insomnia Survey (AIS). Design/Setting: Cross-sectional telephone survey. Participants: National sample of 7,428 employed health plan subscribers (ages 18+). Interventions: None. Measurements and Results: Broadly defined insomnia was assessed with the Brief Insomnia Questionnaire (BIQ). Work absenteeism and presenteeism (low on-the-job work performance defined in the metric of lost workday equivalents) were assessed with the WHO Health and Work Performance Questionnaire (HPQ). Regression analysis examined associations between insomnia and HPQ scores controlling 26 comorbid conditions based on self-report and medical/pharmacy claims records. The estimated prevalence of insomnia was 23.2%. Insomnia was significantly associated with lost work performance due to presenteeism (χ21 = 39.5, P presenteeism equivalent to 11.3 days of lost work performance. This estimate decreased to 7.8 days when controls were introduced for comorbid conditions. The individual-level human capital value of this net estimate was $2,280. If we provisionally assume these estimates generalize to the total US workforce, they are equivalent to annualized population-level estimates of 252.7 days and $63.2 billion. Conclusions: Insomnia is associated with substantial workplace costs. Although experimental studies suggest some of these costs could be recovered with insomnia disease management programs, effectiveness trials are needed to obtain precise estimates of return-on-investment of such interventions from the employer perspective.

    Background Despite advances in clinical chemistry testing, poor blood sample quality continues to impact laboratory operations and the quality of results. While previous studies have identified the preanalytical causes of lower sample quality, few studies have examined the economic impact of poor sample quality on the laboratory. Specifically, the costs associated with workarounds related to fibrin and gel contaminants remain largely unexplored. Methods A quantitative survey of clinical chemistry laboratory stakeholders across 10 international regions, including countries in North America, Europe and Oceania, was conducted to examine current blood sample testing practices, sample quality issues and practices to remediate poor sample quality. Survey data were used to estimate costs incurred by laboratories to mitigate sample quality issues. Results Responses from 164 participants were included in the analysis, which was focused on three specific issues: fibrin strands, fibrin masses and gel globules. Fibrin strands were the most commonly reported issue, with an overall incidence rate of ∼3%. Further, 65% of respondents indicated that these issues contribute to analyzer probe clogging, and the majority of laboratories had visual inspection and manual remediation practices in place to address fibrin- and gel-related quality problems (55% and 70%, respectively). Probe maintenance/replacement, visual inspection and manual remediation were estimated to carry significant costs for the laboratories surveyed. Annual cost associated with lower sample quality and remediation related to fibrin and/or gel globules for an average US laboratory was estimated to be $100,247. Conclusions Measures to improve blood sample quality present an important step towards improved laboratory operations.

    Objectives: Poor adherence to antipsychotic treatment is a widespread problem within schizophrenia therapy with serious consequences including increased risks of relapse and rehospitalization. Mounting evidence supports the key roles that nurses play in monitoring patient progress and facilitating long-term treatment adherence. The Adherencia Terapéutica en la Esquizofrenia (ADHES) nurses’ survey was designed to assess the opinions of nurses on the causes and management of partial/nonadherence to antipsychotic medication. Methods: A questionnaire-based cross-sectional survey of 4120 nurses from Europe, the Middle East and Africa. Interpretation of results was based on a descriptive comparison of responses. Results: Nurses perceived 54% of patients seen in the preceding month to be partially/nonadherent to treatment. Most nurses (90%) reported some level of experience with administration of long-acting injectable (LAI) antipsychotics, with 24% of nurses administering >10 injections per month. The majority (85%) of nurses surveyed believed that improving adherence would improve patient outcomes. Nearly half (49%) reported that most of their patients depend on a family member or other nonprofessional carer to remind them to take their medication as prescribed. A similar proportion of nurses (43%) reported that most of their patients relied on a professional to remind them to take medication. Most nurses (92%) felt that ensuring continuous medication with LAI antipsychotics would yield long-term benefits for patients, but their opinion was that over a third of patients were unaware of LAI antipsychotic treatments. In a series of forced options, the strategy used most often by respondents (89%) to promote medication adherence was to build trusting relationships with patients while listening to and interpreting their needs and concerns. Respondents also rated this as the most effective strategy that they used (48%). Conclusion: Nurses are highly aware of adherence

    Full Text Available BACKGROUND. In Ukraine, an estimated 8.5 million induced abortions have been performed during the years of independence. To examine the reproductive health of Ukrainians, the National Health Survey was conducted in 2007 as a nationally representative cross-sectional survey involving 6841 women and 3178 men aged 15-49. Based on the survey data we aimed to identify the determinants of induced abortion. METHODS. The sample for analysis included 4953 women that have ever been pregnant. As an outcome measure we took induced abortion as the result of the last pregnancy versus all other pregnancy outcomes (live births, miscarriages, and stillbirths. Independent variables included age at the time of pregnancy, region, type of place of residence, religion, time since the end of pregnancy, age at first intercourse, whether first intercourse was at first marriage, and number of previous pregnancies. The first step of the analysis was conducted using the bivariate analysis (crosstabulation and chi-square test. The multivariate analysis was done using the binary logistic regression (backward conditional methods. RESULTS. In multivariate analysis, only five variables were associated at the 0.05 level: region, type of place of residence, religion, age at the time of pregnancy, and number of previous pregnancies. Women from the Western regions and those who live in large cities were less likely to have an induced abortion at the last pregnancy. With the increasing of age and number of previous pregnancies the risk of having an induced abortion at the last pregnancy increases as well. CONCLUSIONS. Women of older age groups, who already have children, those living in smaller settlements and in non-Western regions, are at increased risk of induced abortion. These groups are to be considered while developing programs to facilitate access to effective contraception.

    Background Graphics are increasingly used to represent the spread of infectious diseases (e.g., influenza, Zika, Ebola); however, the impact of using graphics to adequately inform the general population is unknown. Objective To examine whether three ways of visually presenting data (heat map, dot map, or picto-trendline)—all depicting the same information regarding the spread of a hypothetical outbreak of influenza—influence intent to vaccinate, risk perception, and knowledge. Design Survey with participants randomized to receive a simulated news article accompanied by one of the three graphics that communicated prevalence of influenza and number of influenza-related deaths. Setting International online survey Participants 16,510 adults living in 11 countries selected using stratified random sampling based on age and gender Measurements After reading the article and viewing the presented graphic, participants completed a survey that measured interest in vaccination, perceived risk of contracting disease, knowledge gained, interest in additional information about the disease, and perception of the graphic. Results Heat maps and picto-trendlines were evaluated more positively than dot maps. Heat maps were more effective than picto-trendlines and no different from dot maps at increasing interest in vaccination, perceived risk of contracting disease, and interest in additional information about the disease. Heat maps and picto-trendlines were more successful at conveying knowledge than dot maps. Overall, heat maps were the only graphic to be superior in every outcome. Limitations Results are based on a hypothetical scenario Conclusion Heat maps are a viable option to promote interest in and concern about infectious diseases. PMID:28647168

    Full Text Available In a demographic sense, adolescents are a population group which is yet to take part in birth giving. Therefore, their sexual behavior and especially sexual activity at early ages which is not only unfavorable from the aspect of the individual, meaning risk for psycho-physical health, but from the aspect of society as well, as regards population fertility, deserves special attention. This paper shows the results of in-depth research carried out in Belgrade from September 2001 to October 2002 with an aim to establish which factors determine a young person, of sixteen years old or younger, to become sexually active. It was carried out on a sample of 111 adolescent girls between 14 and 20 years old which turned to the Republic Family Planning Center Youth Counseling Clinic of the Institute for Mother and Child Health Care of Serbia. The research showed that sexual experience, realized at an early age was an integral part of development and maturing for the largest number of surveyed girls. In the largest number of cases it was a positive experience, induced by love and experienced with a partner, mainly of the same age, with which they were in a longer, stable relationship. Nevertheless, it could be concluded from the results obtained by the research that the surveyed girls could have more easily and efficiently solved their problems and dilemmas regarding sexuality had they had the possibility to obtain a better insight into their personal feelings and feelings of others at the right time, as well as developed social experience and experience in mastering control of their impulses. With a certain number of surveyed girls that would have meant a delay in their sexual activities to a later age. This also refers to the prevention of other risky behavior such as use of alcohol and drugs, which also have an influence on changing sexual behavior, making it more risky. It is important to stress that the surveyed adolescent girls themselves recognized the

    Full Text Available In Georgia a law was passed in 2005 that banned the import and sale of non-iodized salt. To measure the impact of this legislation, a national survey was conducted in November 2005. A cross-sectional school-based 30 cluster survey of children aged 6—12 years measured urinary iodine excretion (UIE and the iodine content of household salt. Approximately 30 children from each school were requested to provide a urine sample and bring a household salt sample to school. Urine samples were sent for laboratory analysis to Brussels University (Belgium, and salt samples were analyzed onsite using rapid kits. Only 40 (4.4% of 900 urinary samples analyzed had a low UIE (below 100 @мg/L; the median UIE was 320.7 @мg/L. Of 957 salt samples analyzed with rapid salt testing kits, 867 (95.9% were adequately iodized (>15 mg/kg, and only 39 (4.1% had no iodine. Iodization of salt was validated in 136 random samples using iodometric titration; 128 (94.1% were adequately iodized. These results indicate dramatic improvements both in the prevalence of low UIE among Georgian children (80% in 1998 and in the percentage of Georgian households using salt with adequate iodine (8% in 1999 and 67% in 2003. These results show that, Georgia has achieved universal salt iodization (USI and now meets the primary WHO, UNICEF and ICCIDD criteria for elimination of iodine deficiency.

    Background An optimal management of maternal hyperthyroidism is important for positive pregnancy outcome, and to this end, the Endocrine Society published their guidelines in 2007. This survey aimed to investigate to what extent the clinical practice relating to the management of hyperthyroidism during pregnancy in Europe is uniform and consistent with the guidelines. Materials and Methods: We e-mailed an online questionnaire survey based on clinical case scenarios to 605 members of the European Thyroid Association. We analysed 190 responses from 28 European countries. Results For a woman with newly diagnosed Graves' disease (GD) and wishing pregnancy, 78% of the responders would initiate antithyroid drugs (ATDs), while 22% would recommend definitive treatment with radioiodine or surgery. In case of a relapsed GD before pregnancy, 80% preferred definitive treatment. For a woman with newly diagnosed GD during pregnancy, 53% would treat with propylthiouracil, 12% with methimazole, and 34% with propylthiouracil initially and switch to methimazole after the first trimester. Responders used several combinations of tests to monitor the dose of ATDs, and the thyroid test results they targeted were inconsistent. For a lactating woman with GD, 68% would give ATDs without stopping lactation. Conclusions Variation in the clinical practices surrounding the management of hyperthyroid pregnant women in Europe still exists. PMID:25422798

    Background Burden-of-illness data, which are often used in setting healthcare policy-spending priorities, are unavailable for mental disorders in most countries. Aims To examine one central aspect of illness burden, the association of serious mental illness with earnings, in the World Health Organization (WHO) World Mental Health (WMH) Surveys. Method The WMH Surveys were carried out in 10 high-income and 9 low- and middle-income countries. The associations of personal earnings with serious mental illness were estimated. Results Respondents with serious mental illness earned on average a third less than median earnings, with no significant between-country differences (χ2(9) = 5.5–8.1, P = 0.52–0.79). These losses are equivalent to 0.3–0.8% of total national earnings. Reduced earnings among those with earnings and the increased probability of not earning are both important components of these associations. Conclusions These results add to a growing body of evidence that mental disorders have high societal costs. Decisions about healthcare resource allocation should take these costs into consideration.

    Full Text Available The main purpose of this study was to address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA were used. The Factor Analysis Dataset (N = 975 was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Results also indicated that attention problems are predictive of self-reported firesetting. The National Survey Dataset (N =1,158 was analyzed to determine the prevalence of firesetting in a normative sample and also examine whether these children reported higher levels of internalizing and externalizing behavior problems. It was found that 4.5% of adolescents in the generalized sample reported firesetting. Firesetters reported more internalizing, externalizing and total problems than their non-firesetting peers. In this normative sample, firesetters were found to have lower academic performance and more attention problems. Limitations include the low overall number of firesetters in each dataset (Factor Analysis n = 123 and National Survey n = 53 and the inclusion of children who had been referred for services in the Factor Analysis Dataset.

    Full Text Available Objective: to identify the characteristics and reasons reported by Brazilian students for school bullying. Method: this cross-sectional study uses data from an epidemiological survey (National Survey of School Health conducted in 2012. A total of 109,104 9th grade students from private and public schools participated. Data were collected through a self-applied questionnaire and the analysis was performed using SPSS, version 20, Complex Samples Module. Results: the prevalence of bullying was 7.2%, most frequently affecting Afro-descendant or indigenous younger boys, whose mothers were characterized by low levels of education. In regard to the reasons/causes of bullying, 51.2% did not specify; the second highest frequency of victimization was related to body appearance (18.6%; followed by facial appearance (16.2%; race/color (6.8%; sexual orientation 2.9%; religion 2.5%; and region of origin 1.7%. The results are similar to those found in other sociocultural contexts. Conclusion: the problem belongs to the health field because it gathers aspects that determine the students' health-disease-care continuum.

    Cannabis prohibition can generally be regarded as the main driver for home growing of marijuana. In this paper, I discuss the impact of drug prohibition on cannabis cultivators from the three German-speaking countries: Germany, Austria and Switzerland. In particular, this refers to the questions; how illicitness influences motivations for growing; which precautionary measures are taken against the risk of discovery; how penal consequences differ in the three countries and how these aspects are linked to each other. The results come from a sample of 1578 respondents from the German-language online survey conducted following the International Cannabis Cultivation Questionnaire (ICCQ). The survey was carried out in late 2012 and early 2013. While most of the reasons for growing cannabis relate to avoiding negative consequences of prohibition, the illicitness of cannabis also plays a major role for concern about the cultivation activities as well as measures to avoid negative consequences. Swiss growers are less worried about their activity compared to respondents from Germany or Austria. The results confirm the notion that the illicitness of cannabis is the main drive for the private cultivation of the plant. At the same time, prohibition is the principal reason for concern regarding the growing activity. The severity of possible sentences seems to be linked to the degree of concern and precautionary measures. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Background. Quality indicators for colonoscopy have been developed, but the uptake of these metrics into practice is uncertain. Our aims were to assess physician perceptions regarding colonoscopy quality measurement and to quantify the perceived impact of quality measurement on clinical practice. Methods. We conducted in-person interviews with 15 gastroenterologists about their perceptions regarding colonoscopy quality. Results from these interviews informed the development of a 34-question web-based survey that was emailed to 1,500 randomlyselected members of the American College of Gastroenterology. Results. 160 invitations were undeliverable, and 167 out of 1340 invited physicians (12.5% participated in the survey. Respondents and nonrespondents did not differ in age, sex, practice setting, or years since training. 38.8% of respondents receive feedback on their colonoscopy quality. The majority of respondents agreed with the use of completion rate (90% and adenoma detection rate (83% as quality indicators but there was less enthusiasm for withdrawal time (61%. 24% of respondents reported usually or always removing diminutive polyps solely to increase their adenoma detection rate, and 20% reported prolonging their procedure time to meet withdrawal time standards. Conclusions. A minority of respondents receives feedback on the quality of their colonoscopy. Interventions to increase continuous quality improvement in colonoscopy screening are needed.

    Patient decision aids are one possibility for enabling and encouraging patients to participate in medical decisions. This paper aims to describe patients' information and decision-making needs as a prerequisite for the development of high-quality, web-based patient decision aids for affective disorders. We conducted an online cross-sectional survey by using a self-administered questionnaire including items on Internet use, online health information needs, role in decision making, and important treatment decisions, performing descriptive and comparative statistical analyses. A total of 210 people with bipolar disorder/mania as well as 112 people with unipolar depression participated in the survey. Both groups specified general information search as their most relevant information need and decisions on treatment setting (inpatient or outpatient) as well as decisions on pharmacological treatment as the most difficult treatment decisions. For participants with unipolar depression, decisions concerning psychotherapeutic treatment were also especially difficult. Most participants of both groups preferred shared decisions but experienced less shared decisions than desired. Our results show the importance of information for patients with affective disorders, with a focus on pharmacological treatment and on the different treatment settings, and highlight patients' requirements to be involved in the decision-making process. Since our sample reported a chronic course of disease, we do not know if our results are applicable for newly diagnosed patients. Further studies should consider how the reported needs could be addressed in health care practice.

    This study evaluated macro- and micro-level variables associated with individuals' perception of the ending of youth, the beginning of old age, and the length of the middle age period. The European Social Survey is a biennial multi-country, cross-sectional survey. Our analysis is based on the fourth wave, which included a rotating module on ageism. The source sample consisted of 28 countries and a total of 54,988 respondents. Whereas macro-level variability accounted for 14 % of the variance associated with the perception of the ending of youth, only 5.7 % of the variance associated with the perception of the beginning of old age was accounted for by macro-level variability. Almost 10 % of the variance associated with the perception of the middle age period was associated with macro-level variability. Different patterns of macro- and micro-level correlates emerged for the ending of youth, beginning of old age, and the period of middle age. Overall, results demonstrate that individual differences in the perception of the ending of youth, the beginning of old age, and the length of the middle age period are more pronounced than contextual differences. Results also suggest that individuals' mental maps regarding the timing of these events are not necessarily concordant.

    In Colombia, chronic diseases represent a significant health burden. The promotion of physical activity has demonstrated effectiveness in terms of their control. The surveillance of physical activity levels in different age groups permits the design of specific interventions, monitoring and evaluation. To estimate the prevalence of global physical activity, sedentarism, physical activity for transportation and physical activity at school, among adolescent students in five Colombian cities. The Global School-based Health Survey was implemented in public and private schools of five Colombian cities: Bogotá, Bucaramanga, Cali, Manizales y Valledupar. Students were selected through a multi-stage sampling procedure. The survey was anonymous, voluntary and self-processed by students. Statistical analysis was performed at the CDC. The results are representative for adolescent students of each city. The reported recommended levels of physical activity in students from 13 to 15 years ranged from 9 % to 19.8 % in the five cities, being constantly higher among males. Overall, 50.3 % of the students reported not being physically active for transportation to school. 50.3 % of the students played video or computer games or used a computer for 3 or more hours a day. The results indicate low levels of physical activity among students of the five main cities in Colombia, pointing towards the need of interventions at different levels and the need for continuing surveillance.

    In 1979, the results of an operation and maintenance fabric filter survey conducted by APAC were presented. In view of the potential usefulness of such information, Manhattan college was requested by APAC to follow up the initial survey with another improved version. To maximize the usefulness and insure a greater degree of validity to the conclusions, it was decided to limit the participants to users of coal-fired boilers only. A more comprehensive questionaire and one more suitable to computer interpretation than that used in the first study was developed and employed. In this paper, the results of an analysis of these data are presented. Some of the conclusions and opinions of the authors include: (1) Bag life may well be greater than the 2-3 yr reported in the literature, a fact that could reduce projected operating costs for proposed units. (2) Abrasion/erosion difficulties, once a major factor for baghouse users, apparently has been resolved by the equipment manufacturers. (3) Compliance is not a problem with the baghouse. (4) Both utilities and industry would recommend a baghouse to control fly ash for other boilers. (5) O and M problems are more severe with pulse-jet than with reverse-air systems. (6) The three most prevalent O and M problems appear to be higher than design pressure drop, bag failure, and the fly ash handling system.

    Integrity management programs designed to maintain safe pipeline systems quite often will use survey results from In line inspection (ILI) tools in addition to data from other sources. Commonly referred to a "smart pigs," one of the most widely used types are those based upon the magnetic flux leakage technique, typically used to detect and quantify metal loss zones. The majority of pipelines surveyed to date have used tools with the magnetic field direction axially aligned with the length of the pipeline. In order to enable detection and quantification of extremely narrow metal loss features or certain types of weld zone anomalies, tools employing magnetic circuits directing the magnetic fields around the pipe circumference have been designed and are use in segments where these feature categories are a primary concern. Modeling and laboratory test data of metal loss features will be used to demonstrate the response of extremely narrow metal loss zones as the features are rotated relative to the induced field direction. Based upon these results, the basis for developing a magnetizer capable of creating fields oblique to either pipeline axis will be presented along with the magnetic field profile models of several configurations.

    The purpose of this paper is to establish a three-dimensional model of sliding friction and to study the influence of surface topography fractal parameters on the model. Firstly, the analysis of the contact between two asperities is completed, for according to the classical molecular-mechanical friction theory, the sliding friction among rough surfaces should be the sum of mechanical force and molecular adhesion. Then based on the fractal theory, the three-dimensional fractal model of sliding friction is deduced. Finally, the influence of the maximum contact area of asperity al, the fractal roughness G and the fractal dimension D on the sliding friction is analyzed by a simulation example, and the analysis results show that the sliding friction F has positive correlation with al and G, and there is an optimal fractal dimension D which minimizes F. The study of the paper can be used to explain the existing experimental results and the friction theory reasonably.

The study of the paper can be used to explain the existing experimental results and the friction theory reasonably.

    Full Text Available The control of anti-lock braking system is a great challenge, because of the nonlinear and complex characteristics of braking dynamics, unknown parameters of vehicle environment and system parameter variations. Using some of robust control methods, such as sliding mode control, can be a right solution for these problems. In this paper, we introduce a novel approach to design of ABS controllers, which is based on digital sliding mode control with only input/output measurements. The relay term of the proposed digital sliding mode control is filtered through digital integrator, reducing the chattering phenomenon in that way, and the additional signal of estimated modelling error is introduced into control algorithm to enhance the system steady-state accuracy. The given solution was verified in real experimental framework and the obtained results were compared with the results of implementation of two other digital sliding mode control algorithms. It is shown that it gives better system response, higher steady-state accuracy and smaller chattering.

    Although traditional medicine (TM) in South Korea is included in the national health care system, it is considered complementary and alternative medicine (CAM), and not mainstream medicine. Therefore, the lack of statistical data regarding the usage and adverse experiences of traditional Korean medicine (TKM) makes difficult to understand the current status of TM. In this study, we aimed to report usage patterns and adverse experiences on TKM targeting consumers in South Korea. A total of 2000 consumers participated in the survey on usage and adverse experiences in 2008. Among the 2,000 participants, 915 (45.8%) had taken herbal medicine or received traditional medicinal therapies; these individuals were further surveyed on the internet or in an interview. The usage rate was higher among women and among patients in their 30s. Of the total TKM usage, acupuncture accounted for 36.7%, and herbal medicine accounted for 13.4%. Regarding the frequency of use of TKM, 73.8% of patients reported using TM less than 5 times in 1 year. Of the 915 respondents, 8.2% of individuals had some type of adverse experience resulting from TKM. Adverse experiences were primarily caused by acupuncture and herbal medicines, and they primarily involved diseases of the digestive system and skin. The incidence of adverse experiences was less than 3.7% for acupuncture and 3.8% for herbal medicine. Overall, the incidence rate of adverse experiences for TKM for the entire population was 0.04 per 10,000 individuals. The medical usage and occurrence of adverse events on TKM should be surveyed periodically, and the statistical trends should be analysed. The disparity between the survey results for traditional herbal medicines and medical practices, and those for the national pharmacovigilance system or academic reports of adverse experiences should be examined. The national pharmacovigilance system must be improved to compensate for the disparities. Policies and regulations are required to enhance

    Schizophrenia is a serious mental disorder affecting approximately 29 million people worldwide. The ideal treatment and care of patients with schizophrenia should be provided by a multidisciplinary 'team' involving psychiatrists, nurses and other healthcare professionals, together with carers and patients. In light of the key role carers play in the care of patients with schizophrenia, the present survey was designed to assess the opinions of family members and friends of patients with schizophrenia across Europe and to ascertain their attitudes towards the illness, medication and adherence to medication. Among carers participating in this survey, there was widespread awareness of the issues involved in supporting patients with schizophrenia and the importance of their role in improving poor adherence to medication. Three differences in opinion emerged between the views of carers and psychiatrists; psychiatrists rely more on the patient themselves when assessing adherence than carers would recommend; in contrast to psychiatrists, many carers believe the illness itself contributes to non-adherence; two thirds of carers think that schizophrenia medication damages health (higher than estimated by psychiatrists). The findings from the present survey, taken together with the results from the Adherencia Terapéutica en la Esquizofrenia surveys of psychiatrists and nurses, support the need for a collaborative approach to the issue of treatment nonadherence. In particular, healthcare professionals should recognize the valuable contribution that family carers can make to improve treatment adherence and consequently clinical outcomes for patients with schizophrenia. Schizophrenia carries a significant burden for families providing care. The Adherencia Terapéutica en la Esquizofrenia (ADHES) carers' survey was designed to assess the opinions of family and friends of patients with schizophrenia across Europe and ascertain their attitudes towards the illness, medication and

    M-dwarf stars are prime targets for exoplanet searches because of their close proximity and favorable properties for both planet detection and characterization, with current searches around these targets having already discovered several Earth-sized planets within their star’s habitable zones. However, the atmospheric characterization and potential habitability of these exoplanetary systems depends critically on the high-energy stellar radiation environment from X-rays to NUV. Strong radiation at these energies can lead to atmospheric mass loss and is a strong driver of photochemistry in planetary atmospheres. Recently, the MUSCLES Treasury Survey provided the first comprehensive assessment of the high-energy radiation field around old, planet hosting M-dwarfs. However, the habitability and potential for such exoplanetary atmospheres to develop life also depends on the evolution of the atmosphere and hence the evolution of the incident radiation field. The strong high-energy spectrum of young M-dwarfs can have devastating consequences for the potential habitability of a given system. We, thus, introduce the Far Ultraviolet M-dwarf Evolution Survey (FUMES), a new HST-STIS observing campaign targeting 10 early-mid M dwarfs with known rotation periods, including 6 targets with known ages, to assess the evolution of the FUV radiation, including Lyα, of M-dwarf stars with stellar rotation period. We present the initial results of our survey characterizing the FUV emission features of our targets and the implications of our measurements for the evolution of the entire high-energy radiation environment around M-dwarfs from youth to old age.

    Background Malaria is endemic throughout Malawi, but little is known about quality of malaria case management at publicly-funded health facilities, which are the major source of care for febrile patients. Methods In April–May 2011, we conducted a nationwide, geographically-stratified health facility survey to assess the quality of outpatient malaria diagnosis and treatment. We enrolled patients presenting for care and conducted exit interviews and re-examinations, including reference blood smears. Moreover, we assessed health worker readiness (e.g., training, supervision) and health facility capacity (e.g. availability of diagnostics and antimalarials) to provide malaria case management. All analyses accounted for clustering and unequal selection probabilities. We also used survey weights to produce estimates of national caseloads. Results At the 107 facilities surveyed, most of the 136 health workers interviewed (83%) had received training on malaria case management. However, only 24% of facilities had functional microscopy, 15% lacked a thermometer, and 19% did not have the first-line artemisinin-based combination therapy (ACT), artemether-lumefantrine, in stock. Of 2,019 participating patients, 34% had clinical malaria (measured fever or self-reported history of fever plus a positive reference blood smear). Only 67% (95% confidence interval (CI): 59%, 76%) of patients with malaria were correctly prescribed an ACT, primarily due to missed malaria diagnosis. Among patients without clinical malaria, 31% (95% CI: 24%, 39%) were prescribed an ACT. By our estimates, 1.5 million of the 4.4 million malaria patients seen in public facilities annually did not receive correct treatment, and 2.7 million patients without clinical malaria were inappropriately given an ACT. Conclusions Malawi has a high burden of uncomplicated malaria but nearly one-third of all patients receive incorrect malaria treatment, including under- and over-treatment. To improve malaria case

    After the Fukushima nuclear power plant accident on March 11, 2011, the public of Japan became particularly concerned about the possibility of an increased risk of childhood thyroid cancer, similar to what was observed after the Chernobyl's accident. Due to serious public health perception, there was an urgency to evaluate the baseline levels of childhood thyroid status in Fukushima prefecture. Therefore we have commenced a thyroid ultrasound examination (TUE) survey of the approximately 360,000 pediatric inhabitants (0 to 18 years of age) who lived in Fukushima at the time of the accident in October 2011. The subjects were divided into three categories according to the standardized diagnostic criteria of ultrasound findings. Category A contained the subjects whose TUE findings were intact or benign. Category B were recommended a confirmatory TUE. Category C was recommended an immediate confirmatory TUE. The survey of 40,302 subjects in the first year was completed in March, 2013. There were 40,097 (99.5%), 205 (0.50%) and 0 subjects in categories A, B and C, respectively. Of the 82 category B subjects who underwent fine needle aspiration cytology (FNAC), 12 were diagnosed with a malignant tumor or were suspected to have malignancy. The 12 subjects received thyroid surgery and 11 thyroid cancers and one benign nodule were confirmed histologically after surgery. This is the first large-scaled TUE survey to employ sophisticated ultrasound screening and aim to evaluate the baseline frequency of childhood thyroid nodules and cysts. The results will become the golden standard of future comparative TUE in Fukushima, Japan.

    Full Text Available Objectives: To investigate the link between self-reported oral health and arthritis in the Scottish population using data from the Scottish Health Survey. Material and Methods: Data were available from 2008 to 2013 on self-reported arthritis, oral health conditions and oral hygiene habits from the Scottish Health Survey. Arthritis was defined in this survey by self-reported long standing illness, those who reported having arthritis, rheumatism and/or fibrositis. Oral conditions were defined by self-reported bleeding gums, toothache, biting difficulties and/or edentulousness. Oral hygiene habits were defined by self-reported brushing teeth and/or using dental floss on daily basis. Logistic regression was used for statistical analysis adjusted for age, gender, qualification, smoking and body mass index. Results: Prevalence of self-reported arthritis was 9.3% (95% confidence interval [CI] = 9.03 to 9.57. Those who reported having bleeding gums (adjusted odds ratio [OR] = 1.63; 95% CI = 1.35 to 1.96, toothache (OR = 1.32; 95% CI = 1.16 to 1.5, biting difficulties (OR = 1.95; 95% CI = 1.62 to 2.34, and being edentulous (OR = 1.22; 95% CI = 1.08 to 1.37 had an increased risk of arthritis. Brushing teeth (OR = 1.25; 95% CI = 0.74 to 2.12, and using dental floss (OR = 1.11; 95% CI = 0.89 to 1.39 were not associated with arthritis. Conclusions: Self-reported oral conditions were associated with increased risk of self-reported arthritis. Oral hygiene habits were not associated with self-reported arthritis. Further investigation is required to assess the causal association between oral hygiene, oral disease and arthritis.

    Background: Chronic kidney disease is an important risk factor for death and cardiovascular-related morbidity, but estimates to date of its prevalence in Canada have generally been extrapolated from the prevalence of end-stage renal disease. We used direct measures of kidney function collected from a nationally representative survey population to estimate the prevalence of chronic kidney disease among Canadian adults. Methods: We examined data for 3689 adult participants of cycle 1 of the Canadian Health Measures Survey (2007–2009) for the presence of chronic kidney disease. We also calculated the age-standardized prevalence of cardiovascular risk factors by chronic kidney disease group. We cross-tabulated the estimated glomerular filtration rate (eGFR) with albuminuria status. Results: The prevalence of chronic kidney disease during the period 2007–2009 was 12.5%, representing about 3 million Canadian adults. The estimated prevalence of stage 3–5 disease was 3.1% (0.73 million adults) and albuminuria 10.3% (2.4 million adults). The prevalence of diabetes, hypertension and hypertriglyceridemia were all significantly higher among adults with chronic kidney disease than among those without it. The prevalence of albuminuria was high, even among those whose eGFR was 90 mL/min per 1.73 m2 or greater (10.1%) and those without diabetes or hypertension (9.3%). Awareness of kidney dysfunction among adults with stage 3–5 chronic kidney disease was low (12.0%). Interpretation: The prevalence of kidney dysfunction was substantial in the survey population, including individuals without hypertension or diabetes, conditions most likely to prompt screening for kidney dysfunction. These findings highlight the potential for missed opportunities for early intervention and secondary prevention of chronic kidney disease. PMID:23649413

    The immunogenicity profile of a biotherapeutic is determined by a multitude of product and patient-related risk factors that can influence the observed incidence and clinical consequences of immunogenicity. Pre-existing antibodies, i.e., biotherapeutic-reactive antibodies present in samples from treatment-naïve subjects, have been commonly observed during immunogenicity assessments; however their relevance in terms of the safety and efficacy of a biotherapeutic is poorly understood. An American Association of Pharmaceutical Scientists-sponsored survey was conducted to gather information about the prevalence, nature, and consequences of pre-existing antibodies in clinical and nonclinical studies. The survey results indicate that pre-existing antibodies against a variety of biotherapeutics (e.g., mAbs, fusion proteins) are frequently encountered, especially in the context of autoimmune diseases, but that the methods and approaches used to detect, characterize, and report these antibodies vary. In most cases, pre-existing antibodies did not appear to have clinical consequences; however, a few of the respondents reported having observed an effect on pharmacokinetic, pharmacodynamic, safety, and/or efficacy parameters. The findings from this survey are an important first step in evaluating the potential risks associated with the presence of pre-existing antibodies and highlight the importance of standardizing the approaches for detection and characterization of these antibodies. Cross-industry sharing of case studies and relevant data collection will help better inform biotherapeutic risk/benefit profiles and provide deeper understanding of the biological consequences of pre-existing antibodies.

    to assess the intake, frequency, and type of milk consumed by Brazilian children younger than 60 months of age. this was a cross-sectional study, which used secondary data from the National Demographic and Health Survey of 2006-2007. Data from 4,817 children under the age of 60 months were used. All analyses were performed with expanded samples. The dietetic survey assessed the previous day's consumption, and estimates were made through univariate analysis, presented as a percentage. on the day prior to the survey, breast milk was consumed by 91% of the children younger than six months of age, by 61.5% of the children aged 6 to 12 months, and by 34.8% of the children aged 13 to 24 months. Among the children who had received other types of milk, cow's milk was consumed by 62.4% of the children younger than six months, by 74.6% of the children aged 6 to 12 months, and by approximately 80% of the children older than 12 months. Infant formulas were consumed by 23% of the children younger than six months of age, by 9.8% of the children aged 6 to 12 months, and by less than 1% of the older children. Soy milk consumption varied from 14.6% to 20% among the investigated ages. Non-breast milk consumption before the age of six months was more frequent in children living in the Northeastern and Southern regions. the results of the present study demonstrated that most children received cow's milk prematurely as a substitute for breast milk, highlighting the importance of the development of public policies to promote, protect, and support breastfeeding in all regions of Brazil, aiming at reversing the observed scenario.

    A number of noncigarette tobacco products, including some novel products, recently have been marketed by the tobacco industry, which raises concerns from tobacco control authorities. This study aimed to assess current popularity of several noncigarette tobacco products in the U.S. In 2009, a total of 10,587 adults completed a consumer mail-in survey (ConsumerStyles). Based on survey results, the weighted percentages of adults who heard and tried snus, dissolvable tobacco products, flavored little cigars, and flavored cigarettes were computed in 2010. A subset of this sample (n=4556) completed the HealthStyles survey, which included items about health perceptions of these products and use in the past 30 days. The percentage of U.S. adults in the sample who were aware of these products ranged from 10.4% (dissolvable tobacco) to 44.6% (flavored little cigars). One third of adults who had heard of flavored little cigars tried them and 10.1% had used them in the past 30 days; among those who had heard of them, 27.4% tried flavored cigarettes and 12.6% tried snus. In general, young adults, men, and smokers were most likely to have heard of each product. At least one third of adults were uncertain if these products were as harmful as cigarettes (range=37.3% [snus] to 50.3% [dissolvable tobacco]). The awareness of these tobacco products in this sample varied. Groups with a higher prevalence of smoking and tobacco use (e.g., men, people with low levels of education) may be a target audience for marketing and promotions. As availability of products change, continued surveillance is warranted in the U.S. Published by Elsevier Inc.

    The treatment of geriatric patients in the field of trauma surgery is increasingly gaining importance. To provide optimized treatment to these mostly multimorbid patients, interdisciplinary treatment concepts between trauma surgeons and geriatricians have been designed and implemented successfully. The aim of this survey was to evaluate the current state of interdisciplinary management in the treatment of geriatric patients on trauma surgery wards throughout Austria. The directors of 64 Austrian trauma surgery wards were surveyed using an online-questionnaire regarding the current interdisciplinary treatment of geriatric patients. A total of 39 (61 %) questionnaires were analyzed. Of the participating wards, 20 % distinguished between geriatric and non-geriatric patients. There were various criteria to classify the patients. The average percentage of patients older than 70 years was 43 %. Of the participating wards, 26 % had established a periodical cooperation between trauma surgeons and geriatricians and 8 % of the participants stated that there is no interdisciplinary cooperation. The establishment of an interdisciplinary treatment concept in the near future was planned in 28 %. The most commonly mentioned obstacle that prevented trauma surgery wards from establishing an interdisciplinary management model was the lack of personnel resources (59 %) - especially the lack of geriatricians (62 %). The survey's results underline the geriatric trauma surgery's great importance especially regarding the high percentage of geriatric patients, as well as the fact that the significance of the interdisciplinary cooperation between trauma surgeons and geriatricians is not yet perceived by the majority of Austrian trauma surgery wards.

    Poor adherence to antipsychotic treatment is a widespread problem within schizophrenia therapy with serious consequences including increased risks of relapse and rehospitalization. Mounting evidence supports the key roles that nurses play in monitoring patient progress and facilitating long-term treatment adherence. The Adherencia Terapéutica en la Esquizofrenia (ADHES) nurses' survey was designed to assess the opinions of nurses on the causes and management of partial/nonadherence to antipsychotic medication. A questionnaire-based cross-sectional survey of 4120 nurses from Europe, the Middle East and Africa. Interpretation of results was based on a descriptive comparison of responses. Nurses perceived 54% of patients seen in the preceding month to be partially/nonadherent to treatment. Most nurses (90%) reported some level of experience with administration of long-acting injectable (LAI) antipsychotics, with 24% of nurses administering >10 injections per month. The majority (85%) of nurses surveyed believed that improving adherence would improve patient outcomes. Nearly half (49%) reported that most of their patients depend on a family member or other nonprofessional carer to remind them to take their medication as prescribed. A similar proportion of nurses (43%) reported that most of their patients relied on a professional to remind them to take medication. Most nurses (92%) felt that ensuring continuous medication with LAI antipsychotics would yield long-term benefits for patients, but their opinion was that over a third of patients were unaware of LAI antipsychotic treatments. In a series of forced options, the strategy used most often by respondents (89%) to promote medication adherence was to build trusting relationships with patients while listening to and interpreting their needs and concerns. Respondents also rated this as the most effective strategy that they used (48%). Nurses are highly aware of adherence issues faced by their patients; further patient

    Graphics are increasingly used to represent the spread of infectious diseases (e.g., influenza, Zika, Ebola); however, the impact of using graphics to adequately inform the general population is unknown. To examine whether three ways of visually presenting data (heat map, dot map, or picto-trendline)-all depicting the same information regarding the spread of a hypothetical outbreak of influenza-influence intent to vaccinate, risk perception, and knowledge. Survey with participants randomized to receive a simulated news article accompanied by one of the three graphics that communicated prevalence of influenza and number of influenza-related deaths. International online survey. 16,510 adults living in 11 countries selected using stratified random sampling based on age and gender. After reading the article and viewing the presented graphic, participants completed a survey that measured interest in vaccination, perceived risk of contracting disease, knowledge gained, interest in additional information about the disease, and perception of the graphic. Heat maps and picto-trendlines were evaluated more positively than dot maps. Heat maps were more effective than picto-trendlines and no different from dot maps at increasing interest in vaccination, perceived risk of contracting disease, and interest in additional information about the disease. Heat maps and picto-trendlines were more successful at conveying knowledge than dot maps. Overall, heat maps were the only graphic to be superior in every outcome. Results are based on a hypothetical scenario. Heat maps are a viable option to promote interest in and concern about infectious diseases. Published by Elsevier Ltd.

    The purpose of this work was to determine if public communication of science and technology (PCST) has any influence on people's decision to become dedicated to scientific research. For this reason, a national survey involving 852 researchers from all disciplines was conducted in Argentina. The results showed that the factors affecting scientific vocation are many, and that, regardless of differences in gender, age or discipline, the greatest influence on the decision to go into scientific research is exerted by teachers. The analysis also demonstrated that different manifestations of PCST (science books, press articles, audiovisual material, and activities such as visits to science museums) play a significant role in awakening the vocation for science. From these results it may be stated that PCST--in addition to its function of informing and forming citizens--exerts a significant influence in fostering scientific vocation.

    New results of moss survey 2000 of systematic study of air pollution with heavy metals and other toxic elements in Bulgaria are reported. The moss samples collected at 103 sites in Bulgaria, along the borders with Yugoslavia, Macedonia, Greece and Turkey were analyzed by instrumental activation analysis using epithermal neutrons (ENAA) at the IBR-2 pulsed fast reactor for a wide set of elements including heavy metals and rare earth elements (Na, Mg, Al, Cl, K, Ca, Sc, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Mo, Sb, I, Cs, Ba, La, Sm, Tb, Yb, Hf, Ta, W, Au, Th, and U). The results obtained are consistent with the mean European values for most of elements. The principle component analysis is applied to distinguish heavy and light crust elements and vegetation ones from those of anthropogenic origin.

    Dietary fibres are key elements of healthy and balanced diet. The aim of the present study was to explore consumers' knowledge considering fibre, their role in the purchasing decisions, and the cognition of the currently used as well as the possible information sources to encourage the fibre consumption. A questionnaire survey was conducted with 303 respondents. Knowledge about the fibre sources has showed a kind of uncertainty of the respondents, while knowledge about their possible health effects was relatively profound. Internet appeared as a remarkable information source in the topic; however, results pointed out the importance of education, too. Participants more often consuming foodstuffs rich in fibre, women and respondents over 45 years old showed conscious attitudes regarding fibres. Guidelines and education containing authentic information and practical elements are essential, and as a result, consumers' latent knowledge will appear in their conscious food choice decisions.

    'Shifting the Balance of Power' restructured public health in England by abolishing district health authorities and relocating public health in primary care trusts (PCTs). Concern at the time was focused on whether there would be adequate human and other resources available to achieve the expanded public health agenda. A survey was conducted to explore these issues. Postal questionnaire survey of a random sample of members and fellows of the Faculty of Public Health Medicine (FPHM; now Faculty of Public Health). Around 8 months after April 2002, a postal questionnaire survey was sent out to members/fellows and honorary members/fellows of the FPHM. Questions asked about current job status, perception of adequacy of resources and networks, opportunities and challenges, perception of 'job strain', anxiety and depression. The response rate was 229/357 (64%). Respondents from PCTs responded that resources were barely adequate or totally inadequate to deliver the public health agenda (83%); public health networks were said to be adequate by 32% and inadequate by 68%. The PCT respondents were significantly more anxious and depressed than respondents from universities and other organizations, and 28% reported high workloads and low discretion ('job strain'). Eight months after the re-organization of specialist public health in England, there was a substantial impact on individuals working in PCTs. Financial and human resources were perceived as lacking, and levels of anxiety, depression and 'job strain' were high. Future restructuring after 'Choosing Health' must resolve major issues in capacity and capability.

    The Earth surface slide movement at Soledad is a mountain-slide type of movement. Estimations of the thickness of the layer which is moving range between 10 and 100 m. There is no proof that the movement is water induced, but it could be influenced by the water household. The slope of the slide area is H: D = 1: 2. The height difference in the moving area studied, according to this paper, is 1 km. The actual rate of movement is about 12 cm/yr.

    Given today's telecommunications environment, random digit dial (RDD) telephone surveys face declining response rates and coverage, and increasing costs. As an alternative to RDD, we surveyed participants in a randomly recruited standing Internet panel supplemented with a randomly sampled telephone survey of nonpanel members for a study of associations between onset of alcohol use and later alcohol-related problems. The purpose of this paper was to compare results from our survey with results from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face probability sample survey of 43,093 adults, with a focus on associations between demographics, age of drinking onset, and alcohol dependence. Demographic and drinking characteristics from our survey of 4,021 ever-drinkers between the ages of 18 and 39 years were compared with the characteristics of 11,549 similarly aged ever-drinkers from the NESARC. Weighted analyses accounting for sampling design compared these 2 samples on drinking characteristics over the past year and during a respondent's heaviest period of drinking, and in multivariate models examining associations between demographics, age of drinking onset, and lifetime alcohol dependence. Participants in the supplemented Internet panel were similar to the national population of 18- to 39-year-old ever drinkers on gender, education, and race/ethnicity, while adults who were aged 18 to 25 years were under-represented in the Internet panel. The supplemented Internet panel reported higher rates of moderate risk drinking over the past 12 months, lifetime high-risk drinking, and lifetime (ever) alcohol dependence. Estimates of the associations between alcohol dependence and age of drinking onset, risky drinking, and family history of alcohol problems did not significantly differ between the supplemented Internet sample and the NESARC survey. Randomly recruited Internet-based panels may provide an alternative to random digit

    Selective reporting of antibiotic susceptibility test (AST) results is one possible laboratory-based antibiotic stewardship intervention. The primary aim of this study was to identify where and how selective reporting of AST results is implemented in Europe both in inpatient and in outpatient settings. An ESCMID cross-sectional, self-administered, internet-based survey was conducted among all EUCIC (European Committee on Infection Control) or EUCAST (European Committee on Antimicrobial Susceptibility Testing) national representatives in Europe and Israel. Of 38 countries, 36 chose to participate in the survey. Selective reporting of AST results was implemented in 11/36 countries (31%), was partially implemented in 4/36 (11%) and was limited to local initiatives or was not adopted in 21/36 (58%). It was endorsed as standard of care by health authorities in only three countries. The organisation of selective reporting was everywhere discretionally managed by each laboratory, with a pronounced intra- and inter-country variability. The most frequent application was in uncomplicated community-acquired infections, particularly urinary tract and skin and soft-tissue infections. The list of reported antibiotics ranged from a few first-line options, to longer reports where only last-resort antibiotics were hidden. Several barriers to implementation were reported, mainly lack of guidelines, poor system support, insufficient resources, and lack of professionals' capability. In conclusion, selective reporting of AST results is poorly implemented in Europe and is applied with a huge heterogeneity of practices. Development of an international framework, based on existing initiatives and identified barriers, could favour its dissemination as one important element of antibiotic stewardship programmes.

    Based on the analysis and research on the current geographic information sharing and metadata service,we design, develop and deploy a distributed metadata service system based on GeoNetwork covering more than 30 nodes in provincial units of China.. By identifying the advantages of GeoNetwork, we design a distributed metadata service system of national surveying and mapping results. It consists of 31 network nodes, a central node and a portal. Network nodes are the direct system metadata source, and are distributed arround the country. Each network node maintains a metadata service system, responsible for metadata uploading and management. The central node harvests metadata from network nodes using OGC CSW 2.0.2 standard interface. The portal shows all metadata in the central node, provides users with a variety of methods and interface for metadata search or querying. It also provides management capabilities on connecting the central node and the network nodes together. There are defects with GeoNetwork too. Accordingly, we made improvement and optimization on big-amount metadata uploading, synchronization and concurrent access. For metadata uploading and synchronization, by carefully analysis the database and index operation logs, we successfully avoid the performance bottlenecks. And with a batch operation and dynamic memory management solution, data throughput and system performance are significantly improved; For concurrent access, , through a request coding and results cache solution, query performance is greatly improved. To smoothly respond to huge concurrent requests, a web cluster solution is deployed. This paper also gives an experiment analysis and compares the system performance before and after improvement and optimization. Design and practical results have been applied in national metadata service system of surveying and mapping results. It proved that the improved GeoNetwork service architecture can effectively adaptive for distributed deployment

    A variety of dynamical features of sliding bubbles and their impact on wall heat transfer were observed at subcooled flow boiling conditions in a vertical square test channel. Among the wide range of parameters observed, we particularly focus in this paper on (i) the sliding bubbles’ effect on wall heat transfer (supplemantry discussion to the authors’ previous work in Yoo et al. (2016a,b)) and (ii) the wall area influenced by sliding bubbles in subcooled boiling flow. At first, this study reveals that the degree of wall heat transfer improvement due to sliding bubbles depended less on the wall superheat condition as the mass flux increased. Also, the sliding bubble trajectory was found to be one of the critical factors in order to properly describe the wall heat transfer associated with sliding bubbles. In particular, the wall area influenced by sliding bubbles depended strongly on both sliding bubble trajectory and sliding bubble size; the sliding bubble trajectory was also observed to be closely related to the sliding bubble size. Importantly, these results indicate the limitation of current approach in CFD analyses especially for the wall area of bubble influence. In addition, the analyses on the temporal fraction of bubbles’ residence (FR) along the heated wall show that the sliding bubbles typically travel through narrow path with high frequency while the opposite was observed downstream. That is, both FR and sliding bubble trajectory depended substantially on the distance from nucleation site, which is expected to be similar for the quenching heat transfer mode induced by sliding bubbles.

The objective of the current survey was to assess the occurrence of perceived "fragile skin" across different skin types in the general adult population. Methods: Individuals aged 15–65 years from five representative geographic regions (France, Spain, Sweden, Japan, and the US were interviewed and grouped into the following skin types: Caucasian North skin (n=1,218, Caucasian South skin (n=1,695, Asian skin (n=1,500, and Black skin (n=500. The main survey question was "In your opinion, do you have fragile skin?" Concepts relating to the nature and appearance of an individual's skin were also evaluated. Results: A total of 4,913 individuals were interviewed. Subjects in the Caucasian North, Caucasian South, Asian, and Black skin type groups responded positively to the question "In your opinion, do you have fragile skin?" in the following proportions: 24.44%, 29.71%, 52.67%, and 42.20%, respectively. With the exception of individuals in the Black skin group, "fragile skin" was prevalent in significantly more women than men (P<0.0001. Compared with other age categories, the prevalence of "fragile skin" was significantly higher in individuals aged 15–34 years (P<0.0001, regardless of skin type. In general, individuals reporting "fragile skin" were 2–3-fold more likely to respond positively to a series of questions relating to the nature and appearance of their skin. The prevalence of "fragile skin" was also higher in individuals who experienced dermatosis (skin lesions of any type in the previous 12 months. Conclusion: Whilst these

    Objective Since the introduction of legislative changes in 2010, services provided by privately practising nurse practitioners (PPNPs) in Australia have been eligible for subsidisation through the Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS). To provide eligible services, PPNPs must collaborate formally with a medical practitioner or an entity that employs medical practitioners. This paper provides data from a national survey on these collaborative arrangements in Australia. The aim of the study was to evaluate the impact of PPNP services on patient access to care in Australia. Methods PPNPs in Australia were invited to complete an electronic survey. Quantitative data were analysed using descriptive statistics, whereas qualitative data were analysed using thematic analysis. Seventy-three surveys were completed. Results Ninety-three per cent of participants reported having a collaborative arrangement in place. Frequency of communication ranged from daily (27%) to never (1%). Participants reported that collaborative arrangements facilitate learning, patient care and offer support to PPNPs. However, for some PPNPs, organising a formal collaborative arrangement is demanding because it is dependent on the availability and willingness of medical practitioners and the open interpretation of the arrangement. Only 19% of participants believed that collaborative arrangements should be a prerequisite for PPNPs to access the MBS and PBS. Conclusion Although there are benefits to collaborative arrangements, there is also concern from PPNPs that mandating such arrangements through legislation presents a barrier to establishing PPNP services and potentially reduces patient access to care. Collaboration with medical practitioners is intrinsic to nursing practice. Thus, legislating for collaborative arrangements is unnecessary, because it makes the normal abnormal. What is known about the topic? To access the MBS and PBS, PPNPs are required by law to

    Full Text Available BackgroundA growing number of adults with congenital heart disease (ACHD pose a particular challenge for health care systems across the world. Upon turning into 18 years, under the German national health care system, ACHD patients are required to switch from a pediatric to an adult cardiologist or an ACHD-certified provider. To date, reliable data investigating the treatment situation of ACHD patients in Germany are not available.Materials and methodsAn online survey was conducted in collaboration with patient organizations to address the life situation and the conditions of health care provision for ACHD patients in Germany. ACHD patients were recruited from the database of the National Register for Congenital Heart Defects (NRCHD and informed about the survey via email, websites, and social networks. A total of 1,828 ACHD patients (1,051 females participated in this study. The mean age was 31.7 ± 11.7 years. Participants were surveyed about treating physicians and the institution mainly involved in the treatment of their CHD. In addition, participants were asked questions to assess the level of trust toward their treating physician and their familiarity with the term “ACHD-certified provider.”ResultsAmong the surveyed patients, 25.4% stated that they attended a specific ACHD clinic at a heart center regularly, 32.7% were treated in a private practice setting by a pediatric cardiologist, 32.4% in a private practice (adult cardiology setting, and 9.5% were treated by an “other physician.” Only 24.4% of the male and 29.7% of the female ACHD patients were familiar with the term “ACHD-certified provider.”ConclusionThe transfer from pediatric cardiology to ACHD care requires further attention as many adult patients have not transferred to certified ACHD providers. The question of whether ACHD patients in Germany are offered consistent and adequate care should also be investigated in more detail. The answers regarding the ACHD

    The Mission Accessible Near-Earth Objects Survey aims to physically characterize sub-km near-Earth objects (NEOs). We report the first photometric results from the survey that began in 2013 August. Photometric observations were performed using 1–4 m class telescopes around the world. We present rotational periods and light curve amplitudes for 86 sub-km NEOs, though in some cases only lower limits are provided. Our main goal is to obtain light curves for small NEOs (typically, sub-km objects) and estimate their rotational periods, light curve amplitudes, and shapes. These properties are used for a statistical study to constrain overall properties of the NEO population. A weak correlation seems to indicate that smaller objects are more spherical than larger ones. We also report seven NEOs that are fully characterized (light curve and visible spectra) as the most suitable candidates for a future human or robotic mission. Viable mission targets are objects fully characterized, with Δ v {sup NHATS} ≤ 12 km s{sup −1}, and a rotational period P  > 1 hr. Assuming a similar rate of object characterization as reported in this paper, approximately 1230 NEOs need to be characterized in order to find 100 viable mission targets.

    A primary focus of dental education is to teach students the knowledge, skills, and values essential for practicing dentistry. However, the preparation of dentists to manage a business is frequently cited as inadequate. A survey was prepared to assess teachers' opinions of business instructional topics: challenges; desired training; employee benefits; learning resources; importance of business topics; and appropriateness of time allocations. The purpose of this project is to compare opinions of teachers of dental practice management with key management aspects reported for service businesses by the Small Business Development Center (SBDC). Practice management teachers from forty-eight (89 percent) schools responded to the survey. They indicated that several challenges confronting dentists are similar to other service businesses. Dentists, however, rank customer relations appreciably higher. In order of importance of teaching topics, the practice management teachers rank ethics and personnel management as a high priority and planning as a low priority. Awareness of the similarities and differences in the perceptions of practice management teachers and businesspeople may result in instructional improvements.

    People with anxiety disorders are faced with treatment decisions considerably affecting their life. Patient decision aids are aimed at enabling patients to deliberate treatment options based on individual values and to participate in medical decisions. This is the first study to determine patients' information and decision-making needs as a pre-requisite for the development of patient decision aids for anxiety disorders. An online cross-sectional survey was conducted between January and April 2013 on the e-health portal http://www.psychenet.de by using a self-administered questionnaire with items on internet use, online health information needs, role in decision making and important treatment decisions. Descriptive and inferential statistical as well as qualitative data analyses were performed. A total of 60 people with anxiety disorders with a mean age of 33.3 years (SD 10.5) participated in the survey. The most prevalent reasons for online health information search were the need for general information on anxiety disorders, the search for a physician or psychiatrist and the insufficiency of information given by the healthcare provider. Respondents experienced less shared and more autonomous decisions than they preferred. They assessed decisions on psychotherapy, medication, and treatment setting (inpatient or outpatient) as the most difficult decisions. Our results confirm the importance of offering patient decision aids for people with anxiety disorders that encourage patients to participate in decision making by providing information about the pros and cons of evidence-based treatment options.

    Regular physical activity can have a positive effect on health at any age. Today's lifestyles, however, can often be characterised as sedentary. Therefore, the promotion of physical activity and sports has become an integral part of public health measures. The representative data of adults aged 18 to 79 years in Germany obtained from the "German Health Interview and Examination Survey for Adults" (DEGS1) provide an overview of self-estimated current physical activity behaviour. The results show that one third of the adult population claims to pay close attention to reaching a sufficient level of physical activity and one fourth participates in sports for at least 2 h/week on a regular basis. Thus, the percentage of adults regularly engaged in sports has increased compared to the previous "German National Health Interview and Examination Survey 1998". Still, four out of five adults do not achieve at least 2.5 h/week of moderate-intensity physical activity as recommended by the World Health Organisation. Consequently, future individual-level and population-level interventions should focus on target group-specific measures while continuing to promote regular physical activity in all segments of the population.

    In this article, results of a German nationwide survey (KFN schools survey 2007/2008) are presented. The controlled sample of 44,610 male and female ninth-graders was carried out in 2007 and 2008 by the Criminological Research Institute of Lower Saxony (KFN). According to a newly developed screening instrument (KFN-CSAS-II), which was presented to every third juvenile participant (N = 15,168), 3% of the male and 0.3% of the female students are diagnosed as dependent on video games. The data indicate a clear dividing line between extensive gaming and video game dependency (VGD) as a clinically relevant phenomenon. VGD is accompanied by increased levels of psychological and social stress in the form of lower school achievement, increased truancy, reduced sleep time, limited leisure activities, and increased thoughts of committing suicide. In addition, it becomes evident that personal risk factors are crucial for VGD. The findings indicate the necessity of additional research as well as the respective measures in the field of health care policies.

    This study examined the association between workplace mistreatment and occurrence, duration, and costs of sickness absenteeism. We used the 2010 National Health Interview Survey and considered 13,807 employed adult respondents. We used a zero-inflated negative binomial (zinb) model to examine the association between exposure to workplace mistreatment and the occurrence and number of workdays missed due to illness/injury in the preceding 12 months. In 2010, 7.6% of US workers employed at the time of the survey reported having been mistreated at their workplace. Both occurrence and duration of sickness absence were higher for mistreated than for non-mistreated workers. The zinb results showed that being mistreated was associated with a 42% increase in the number of missed workdays, controlling for covariates. The marginal effect analysis showed that lost workdays differed by 2.45 days between mistreated and non-mistreated workers. This implies that workplace mistreatment was associated with $4.1 billion, or 5.5%, of sickness absenteeism costs in 2010. Workplace mistreatment is associated with sickness absence in the United States. While a causal relationship could not be established due to the cross-sectional design of the study, this study reveals the economic importance of developing workplace mistreatment prevention strategies. Published 2013. This article is a U.S. Government work and is in the public domain in the USA.

    In response to the Institute of Medicine (2011) report Occupational Health Nurses and Respiratory Protection: Improving Education and Training, a nationwide survey was conducted in May 2012 to assess occupational health nurses' educational preparation, roles, responsibilities, and training needs in respiratory protection. More than 2,000 occupational health nurses responded; 83% perceived themselves as competent, proficient, or expert in respiratory protection, reporting moderate comfort with 12 respiratory program elements. If occupational health nurses had primary responsibility for the respiratory protection program, they were more likely to perceive higher competence and more comfort in respiratory protection, after controlling for occupational health nursing experience, highest education, occupational health nursing certification, industry sector, Association of Occupational Health Professionals in Healthcare membership, taking a National Institute for Occupational Safety and Health spirometry course in the prior 5 years, and perceiving a positive safety culture at work. These survey results document high perceived competence and comfort in respiratory protection. These findings support the development of targeted educational programs and interprofessional competencies for respiratory protection. Copyright 2013, SLACK Incorporated.

    Full Text Available Objective. To examine the prevalence and correlates of Complementary and Alternative Medicine (CAM use in Lebanon. Methods. A cross-sectional survey was conducted through face to face interviews on a nationally representative sample of 1,475 Lebanese adults. The survey questionnaire explored the sociodemographic and health related characteristics as well as the types and modes of CAM use. The main outcome in this study was the use of CAM during the last 12 months. Results. Prevalence of CAM use was 29.87% with “folk herbs” being the most commonly used (75%. Two out of five CAM users indicated using it as alternative to conventional therapies and only 28.4% of users disclosed the use of CAM to their physician. CAM use was significantly associated with higher income, presence of a chronic disease, and lack of access to needed health care. Lower odds of CAM use were observed among older adults and those with a higher education level. Conclusions. This study revealed a high prevalence of CAM use in Lebanon. Health policy and decision makers need to facilitate proper regulation and integration of CAM into mainstream medicine and educate health care providers and the public alike on the safe and effective use of CAM therapies.

    Functional status decline commonly accompanies hospitalization making patients vulnerable to complications. Such decline can be mitigated through hospital-based early mobility programs. Success in implementing patient mobility quality improvement processes requires evaluating providers' knowledge, attitudes, and behaviors. A cross-sectional, self-administered survey in two different hospital settings was completed by 120 nurses and physical and occupational therapists (rehabilitation therapists, 38; nurses, 82) from six general medicine units. The survey was developed using published guidelines, literature review, and provider meetings and refined through pilot testing. Psychometric properties were assessed, and regression analyses were conducted to examine barriers to early mobility by hospital site, provider discipline, and years of experience. Internal consistency reliability, item consistency, and discriminant validity psychometric characteristics were acceptable. In multivariable regression analysis, overall perceived barriers were similar between the two hospitals (P = 0.25) and significantly higher for staff with less experience (P = 0.02) and for nurses vs. rehabilitation therapists (P mobilizing medical inpatients that were similar across two hospital settings. These results can assist with the implementation of quality improvement projects for increasing early hospital-based patient mobility.

    We present preliminary results of our investigations of inscribed rocks found along the Oregon Coast. The roughly 30 rocks contain Latin letters, numbers, and other signs. Bawlf (2000), after Costaggini and Schultz (1977), suggested that the artifacts represent a survey and longitude observation made by Francis Drake in 1579 during his circumnavigation. We have analyzed old records and photographs, and made preliminary site visits to evaluate if these suggestions have merit. The artifacts were first seen in the late 19th century by settlers along the Nehalem River and inspired early searches for treasure on the mountainside, which is rugged, rocky, and steep. The nearby wreck of a Spanish galleon confounded the interpretations. The director of the local Tillamook County Pioneer Museum, Wayne Jensen, with an enthusiastic colleague, Don Viles, spent two decades looking for artifacts and commissioned the existing site survey from the Civil Engineering Department of Oregon State University. Both Viles (1982, 1990) and Jensen (1990) published descriptions of the finds and their search methods. We present photographs of several of the larger artifacts, our conclusions about what the site represents and who may have created it, and suggestions about the meaning of some of the markings and artifacts, including calculations for possible astronomical observations. We solicit comments from the audience regarding any similar sites.

    Full Text Available Abstract Background End-stage lung disease (ESLD is a frequent cause of death. What are the differences in the supports needed by caregivers of individuals with ESLD at end of life versus other life-limiting diagnoses? Methods The South Australian Health Omnibus is an annual, random, face-to-face, cross-sectional survey. In 2002, 2003 and 2005-2007, respondents were asked a range of questions about end-of-life care; there were approximately 3000 survey participants annually (participation rate 77.9%. Responses were standardised for the whole population. The families and friends who cared for someone with ESLD were the focus of this analysis. In addition to describing caring, respondents reported additional support that would have been helpful. Results Of 1504 deaths reported, 145 (9.6% were due to ESLD. The ESLD cohort were older than those with other 'expected' causes of death (> 65 years of age; 92.6% versus 70.6%; p physical care, information provision, and emotional and spiritual support. Conclusions Caregiver needs were similar regardless of the underlying diagnosis although access to palliative care specialist services occurred less often for ESLD patients. This was despite significantly longer periods of time for which care was provided.

    Since 2000, thyroid cancer has been increasing most rapidly in Korea. Although the cause of the increase is not clear, thyroid cancer screening could be identified as one of its causes. The purpose of this study was to examine the screening rate of thyroid cancer and its related factors using nationwide data. The study population was derived from the 2009 Korea National Cancer Screening Survey (KNCSS), an annual cross-sectional survey that uses a nationally representative random sampling to investigate cancer screening rates. A total of 2,000 Korean adults participated. The screening method of thyroid cancer was restricted to thyroid ultrasonography. Logistic regression was used to identify factors associated with undergoing thyroid cancer screening. Of all participants, 13.2% (8.4% men and 16.4% women) underwent thyroid ultrasonography. On multiple analyses, age, residence, belief in cancer screening, regular health check-ups, smoking, alcohol drinking, and exercise were associated with thyroid cancer screening. Subjects who underwent other cancer screening, such as gastric, colorectal, breast, or cervical, were more likely to have had a thyroid ultrasonogram that those who did not get screened. We presented the number and characteristics of examinees utilized ultrasonography as a thyroid screening tool in Korea. Although these results revealed that cancer screening might play a major role in the increase of thyroid cancer incidence, further research is needed to determine causes of the rapidly increasing incidence of thyroid cancer in Korea.

    The Glasgow Coma Scale (GCS) was introduced 40 years ago and has received world-wide acceptance. The GCS rates eye, motor, and verbal responses to assess the level of consciousness. Concerns have been expressed with regard to reliability and consistency of assessments. We considered that lack of standardization in application techniques and reporting of the GCS may have contributed to these concerns, and aimed to assess current procedures in its use. Questionnaire-based assessments were conducted by an online survey and during neurosurgical training courses. Overall, 616 participants were recruited, representing 48 countries and including physicians and nurses from different disciplines. Use of the GCS was reported by nearly all participants for assessment of patients with traumatic brain injury, but not for all patients with a reduced level of consciousness from other causes (78%). Major differences were found regarding the type of stimulus applied when patients do not obey commands: Nail bed pressure, supraorbital pressure, trapezius or pectoralis pinch, and sternal rub were all frequently used, whereas 25% of responders reported to never use a peripheral stimulus. Strategies for reporting the GCS varied greatly, and 35% of participants limited the reporting to a summary score. Moreover, different approaches were used when one of the components could not be assessed. Overall, the surveys have identified a general lack of standardization in assessment and reporting of the GCS. The results illustrate the need for continued education to improve reliability of assessments through guidance to a standard approach.

  6. AIRLINE ITINERARY CHOICE IN A DYNAMIC SUPPLY ENVIRONMENT: RESULTS FROM A STATED PREFERENCE SURVEY

    Full Text Available This paper investigates the choice of airline itineraries in dynamic settings using a tailored stated preference survey. The paper hypothesizes that airline itinerary choice is not a one-time event, but a continuous process during a certain time frame. Consumers can choose either to purchase an itinerary, deferring choice up to the end of the sales period, or completely declining the purchase. Understanding such consumers’ behavior is specifically relevant to the tourism industry, where firms are extensively utilizing internet websites to offer their products (e.g., airline tickets, hotel rooms to consumers. The paper describes the stated preference survey with real itineraries of various airlines on medium and long-haul routes. Choice sets are composed with dynamic and static variables and socio-economic variables. Questionnaires were distributed electronically among various groups of respondents, yielding a sample of 914 persons. Results show that (i itinerary choice deferring takes place, with differences between tourists and business-travelers, (ii the decision whether to defer choice is affected by dynamically changing variables and by the length of each respondent’s allocated choice period, and (iii the proposed methodology is adequate for investigating choice in dynamic settings and thus indicating its potential for further research in transportation planning and in tourism.

    An optimal management of maternal hyperthyroidism is important for positive pregnancy outcome, and to this end, the Endocrine Society published their guidelines in 2007. This survey aimed to investigate to what extent the clinical practice relating to the management of hyperthyroidism during pregnancy in Europe is uniform and consistent with the guidelines. We e-mailed an online questionnaire survey based on clinical case scenarios to 605 members of the European Thyroid Association. We analysed 190 responses from 28 European countries. For a woman with newly diagnosed Graves' disease (GD) and wishing pregnancy, 78% of the responders would initiate antithyroid drugs (ATDs), while 22% would recommend definitive treatment with radioiodine or surgery. In case of a relapsed GD before pregnancy, 80% preferred definitive treatment. For a woman with newly diagnosed GD during pregnancy, 53% would treat with propylthiouracil, 12% with methimazole, and 34% with propylthiouracil initially and switch to methimazole after the first trimester. Responders used several combinations of tests to monitor the dose of ATDs, and the thyroid test results they targeted were inconsistent. For a lactating woman with GD, 68% would give ATDs without stopping lactation. Variation in the clinical practices surrounding the management of hyperthyroid pregnant women in Europe still exists.

    Studies show that Asian-American subgroups do not always meet dietary recommendations and are at high risk of cardiovascular diseases. The purpose of our research is to illustrate the various sociodemographic correlates of dietary habits for six subgroups of Asian-Americans in California. The 2005 California Health Interview Survey (CHIS) was utilized. A total of 3772 Asian-Americans were included in this study, with the largest subgroup being Chinese (n = 1280; N = 913,798). The outcome variable for this study was dietary behavior defined as consuming five or more fruits and vegetables per day (5-a-day), provided by CHIS. Univariate and multivariable regression analyses were conducted accounting for complex survey design. Being a female (Chinese, Filipina, Korean, and Vietnamese), not being married (Chinese), not being a college graduate (Chinese), living in poverty (South Asian), and speaking only English language at home (Chinese and Japanese) were associated with higher odds of not meeting a 5-a-day requirement. Results highlighted several sociodemographic correlates to not meeting 5-a-day requirement among six Asian-American subgroups. Targeted health promotion measures for such at-risk groups should be implemented to improve dietary practices.

    Background To determine the characteristics associated with having a mentor, the association of mentoring with self-efficacy, and the content of mentor–mentee interactions at the University of California, San Francisco (UCSF), we conducted a baseline assessment prior to implementing a comprehensive faculty mentoring program. Method We surveyed all prospective junior faculty mentees at UCSF. Mentees completed a web-based, 38-item survey including an assessment of self-efficacy and a needs assessment. We used descriptive and inferential statistics to determine the association between having a mentor and gender, ethnicity, faculty series, and self-efficacy. Results Our respondents (n=464, 56%) were 53% female, 62% white, and 7% from underrepresented minority groups. More than half of respondents (n=319) reported having a mentor. There were no differences in having a mentor based on gender or ethnicity (p≥0.05). Clinician educator faculty with more teaching and patient care responsibilities were statistically significantly less likely to have a mentor compared with faculty in research intensive series (pmentor was associated with greater satisfaction with time allocation at work (pmentor, 5.33 (sd = 1.35, pmentors, but rated highest requiring mentoring assistance with issues of promotion and tenure.

    (Written on behalf of the Survey Science Center of the XMM-Newton satellite) The Survey Science Center (SSC) of the XMM-Newton satellite has carried out several large optical campaigns aiming at the spectroscopic identification of samples of about a thousand X-ray sources at various X-ray flux levels and towards different Galactic directions. In addition, the SSC has obtained multi-color wide-field imaging for hundreds of XMM-Newton fields. Building learning samples for the statistical identification of all 2XMM sources was one of the main drivers for undertaking these observing campaigns. However, as demonstrated by the amount of papers published, these collections of data also constitute a very valuable resource which can be used for addressing a wide range of astrophysical issues. We describe the content and architecture of the XID results database recently opened by the SSC and containing a first installment of these data. The interface provides easy selection and browsing through catalogs and access to all optical images and spectral data associated with any given X-ray source as well as all relevant XMM-Newton data. The database was created using the database generator Saada and, together with the XCat-DB already deployed at the Observatoire de Strasbourg, provides another example of the flexibility, ease of use and scalability offered by Saada.

    This report describes the experimental details and interprets results from a study conducted by the U.S. Geological Survey (USGS) in 1992 to assess the effect of different sample-processing treatments on the stability of eight nutrient species in samples of surface-, ground-, and municipal-supply water during storage at 4 degrees Celsius for about 30 days. Over a 7-week period, splits of filtered- and whole-water samples from 15 stations in the continental United States were preserved at collection sites with sulfuric acid (U.S. Environmental Protection Agency protocol), mercury (II) chloride (former U.S. Geological Survey protocol), and ASTM (American Society for Testing and Materials) Type I deionized water (control) and then shipped by overnight express to the USGS National Water Quality Laboratory (NWQL). At the NWQL, the eight nutrient species were determined in splits from each of the 15 stations, typically, within 24 hours of collection and at intervals of 3, 7, 14, 22, and 35 days thereafter. Ammonium, nitrate plus nitrite, nitrite, and orthophosphate were determined only in filtered-water splits. Kjeldahl nitrogen and phosphorus were determined in both filtered-water and whole-water splits.

    General internal medicine (GIM) careers are increasingly viewed as challenging and unsustainable. We aimed to assess academic GIM worklife and determine remediable predictors of stress and burnout. We conducted an email survey. Physicians, nurse practitioners, and physician assistants in 15 GIM divisions participated. A ten-item survey queried stress, burnout, and work conditions such as electronic medical record (EMR) challenges. An open-ended question assessed stressors and solutions. Results were categorized into burnout, high stress, high control, chaos, good teamwork, high values alignment, documentation time pressure, and excessive home EMR use. Frequencies were determined for national data, Veterans Affairs (VA) versus civilian populations, and hospitalist versus ambulatory roles. A General Linear Mixed Model (GLMM) evaluated associations with burnout. A formal content analysis was performed for open-ended question responses. Of 1235 clinicians sampled, 579 responded (47 %). High stress was present in 67 %, with 38 % burned out (burnout range 10-56 % by division). Half of respondents had low work control, 60 % reported high documentation time pressure, half described too much home EMR time, and most reported very busy or chaotic workplaces. Two-thirds felt aligned with departmental leaders' values, and three-quarters were satisfied with teamwork. Burnout was associated with high stress, low work control, and low values alignment with leaders (all p stress and burnout, division rates vary widely. Sustainability efforts within GIM could focus on visit length, staff support, schedule control, clinic chaos, and EMR stress.

    Diagnostic reference levels provide framework to reduce variability. The aim of this study is to establish, for the first time, a baseline for national diagnostic reference levels in Serbia and Montenegro for the most common X-ray examination types. Measurements of patient dose using kerma-area product meter and entrance surface air kerma assessment were performed on at least ten patients for each examination type, in each of 16 randomly selected hospitals in Serbia and Montenegro, so that a total of 3,026 procedures for nine different examination categories were included in the survey. Exposure settings and individual data were recorded for each patient. Mean, median and third quartile values of patient doses are reported. Results have shown wide variation of mean hospital doses, with factor of four for barium enema to 23 for thoracic spine radiography. Entrance surface air kerma were compared with previously published diagnostic reference levels (DRL) proposed by Commission of European Communities (CEC). Doses for all studied examination types except chest radiography were within European DRL. The reasons for dose variation are discussed. Survey data are aimed to help in development of an on-going national quality assurance and quality control programme in diagnostic radiology. The findings emphasize the importance of regular patient dose measurement to ensure that patient doses are kept as low as reasonable achievable.

    Background: Hispanic construction workers experience high rates of occupational injury, likely influenced by individual, organizational, and social factors. Objectives: To characterize the safety climate of Hispanic construction workers using worker, contractor, and supervisor perceptions of the workplace. Methods: We developed a 40-item interviewer-assisted survey with six safety climate dimensions and administered it in Spanish and English to construction workers, contractors, and supervisors. A safety climate model, comparing responses and assessing contributing factors was created based on survey responses. Results: While contractors and construction supervisors’ (n = 128) scores were higher, all respondents shared a negative perception of safety climate. Construction workers had statistically significantly lower safety climate scores compared to supervisors and contractors (30.6 vs 46.5%, Pclimate scores were not associated with English language ability or years lived in the United States. Conclusions: We found that Hispanic construction workers in this study experienced a poor safety climate. The Hispanic construction safety climate model we propose can serve as a framework to guide organizational safety interventions and evaluate safety climate improvements. PMID:26145454

    It is widely taken for granted that the interest in technology decreases with increasing age. Many studies and especially large scale surveys seem to confirm declining technology acceptance; however, it is argued that composition effects (e.g. increasing proportions of women among the older age groups), cohort effects (e.g. experience with different technologies during the lifetime) and various living and health conditions (e.g. living alone, having children in the neighborhood and experience of falls) have to be taken into account and that these factors will have different impacts on the acceptance of different scenarios of assistive technologies. The analyses are based on data from a self-administered questionnaire (n = 2032, a representative random sample of individuals aged 50 years and above in Lower Saxony, Germany). The survey briefly introduced four scenarios of ambient assisted living (AAL) technologies. Multinominal logistic regression was used to explore the correlations of acceptance and the independent variables mentioned. The results show that the simple assumption of an age effect, i.e. technology acceptance generally declines with increasing age, is misleading. An answer to the question whether older people will make use of assistive technologies in the future should consider specific scenarios and also various socioeconomic variables.

    Bipolar disorder is a recurrent and episodic illness. This survey study assessed experiences and identified clinical insights of individuals with bipolar disorder. An Internet-based monitor system database was screened for patients with bipolar disorder in Japan (February and March 2013). Of 1,050 patients, 457 completed surveys, and results were analyzed with descriptive statistics. Approximately one-fourth of respondents were diagnosed with bipolar disorder on their first visit to medical institutions, although the most common initial diagnosis was depression/depressive state (65%). Mean time lag between first-time visit to a medical institution and receipt of correct diagnosis of bipolar disorder was 4 years; one-third of patients experienced more than 5 years of lag time. Three perceived reasons for lapsed time before correct diagnosis were "(patients) Did not consider manic symptoms as illness, and did not tell the doctor about them," "I (patient) did not know of bipolar disorder," and "Lack of communication between my doctor and myself (patient)." Among participants who believed that they were initially incorrectly diagnosed and improperly treated, most experienced socioeconomic problems, such as having long-term inability to work or to study (65%). Sources of encouragement for participants included "To have someone to consult with" (41%) followed by having "People around me treat me the same as before" (40%). Individuals with bipolar disorder reported a time lag of many years before accurate diagnosis, and substantial burden imposed by the illness. Encouragement should be provided for individuals to live positively with bipolar disorder.

    Full Text Available Abstract Background Understanding client perspectives on treatment is increasingly recognized as key to improving care. Yet information on the perceptions and experiences of workers with private insurance coverage who receive help for substance use conditions is relatively sparse, particularly in managed behavioral health care organization (MBHO populations. Furthermore, the role of several factors including prior service use has not been fully explored. Methods Employees covered by a large MBHO who had received substance abuse services in the past year were surveyed (146 respondents completed the telephone survey and self-reported service use. Results The most common reasons for entering treatment were problems with health; home, family or friends; or work. Prior treatment users reported more reasons for entering treatment and more substance use-related work impairment. The majority of all respondents felt treatment helped a lot or some. One quarter reported getting less treatment than they felt they needed. Discussion and conclusions Study findings point to the need to tailor treatment for prior service users and to recognize the role of work in treatment entry and outcomes. Perceived access issues may be present even among insured clients already in treatment.

    Full Text Available Abstract Background There is growing evidence that quality, rather that quantity of fat is the determinant of cardiovascular risk. The objective of the study is to describe quantitatively the intake and adequacy of fatty acid classes among the Mexican population aged 5-90 years from a probabilistic survey. Methods Dietary intake of individual and classes of fatty acids was computed from the dataset of the 2006 Mexican National Health and Nutrition Survey (ENSANUT2006, collected by a food frequency questionnaire. Adequacy was calculated in reference to authoritative recommendations. Results The mean intake of total fatty acids (TFA ≈ 25%E fell within WHO recommendations; the intakes of saturated fatty acids (SFA among all age-groups (45-60% and of trans fatty acids (TrFA in 30% of school-age children and adolescents and 20% of adults exceeded international recommendations. The mean intake of polyunsaturated fatty acids (PUFA and particularly of n6 and n3 PUFAS, was inadequately insufficient in 50% of the sample. Conclusions The main public health concerns are the high intake of SFA and the suboptimal intake of PUFA in Mexican population. The TrFA intake represents a low public health risk.

    Consumers and patients are unsure of whom to trust for nutritional advice. Although medical doctors are seen as experts in nutrition and their advice is regularly followed, data are lacking on the amount of nutrition education in European medical school curricula. In line with US research, we distributed a survey on required and/or optional nutrition contact hours to medical education directors of all accredited medical schools (N=217) in Western European Union countries (N=14). In total, respondents from 32 medical schools (14.7%) from 10 countries indicated that nutrition education, in some form, was required in 68.8% of schools where, on average, 23.68 h of required nutrition education was provided. The results from this small-scale survey are comparable to a 2010 US study; conversely, European educators were satisfied with the amount of nutrition education. We substantiate the increasing concern over the inadequate amounts of nutrition education provided to medical students in Europe.

    To report the blood pressure results from the 2008/09 New Zealand Adult Nutrition Survey (2008/09NZANS). Blood pressure measurements were available for 4,407 adults who were part of a survey involving face-to-face interviews with 4,721 New Zealanders aged 15 years and over. Three measurements were taken one minute apart, and the mean of the second and third readings has been used for this analysis. Hypertension was defined as systolic blood pressure (SBP) greater than and equal to 140 mmHg or diastolic blood pressure (DBP) greater than and equal to 90 mmHg or self reported use of antihypertensive medications. Comparisons were made with previously published New Zealand population blood pressure estimates. Mean SBP for the New Zealand adult population was 126 mmHg. The prevalence of hypertension was 31%, with 15% reporting taking antihypertensive medication. Mean SBP has increased since 2002/03 for New Zealand European and others (NZEO) aged 35-54 years and Maori aged 35-74 years, reversing a downward trend observed in NZEO between 1982 and 2002. The increasing blood pressure levels are concerning. Given the importance of elevated blood pressure as a risk factor for cardiovascular disease, intensive screening, public health measures aimed at lowering population blood pressure, and further population monitoring are warranted.
