  1. Legitimizing Vetoes : A Discourse Analysis of How Vetoes are Motivated in the United Nations Security Council

    OpenAIRE

    Wernersson, Hanna

    2016-01-01

    How is a veto justified? Within the discipline of International Relations, discourse analysis is gaining a higher status. However, there is a surprising lacuna in the literature as a discursive approach to the veto in the United Nations Security Council, is yet to be taken. This is unfortunate, given the Security Council’s prominence. The way in which the council members make meaning through their word choice has profound effects for politics in the international system. There is, nonetheless...

    Veto players are political actors whose consent is necessary to adopt a new policy. Put otherwise, they have veto power which allows them to prevent a change to the status quo. The concept is crucial to the influential veto player theory developed by George Tsebelis. Building on earlier work in

    Data taken by interferometers for gravitational waves include noises caused by instabilities of the interferometers. Veto analyses to remove false events caused by detectors are then necessary to detect real gravitational waves or to obtain a lower upper limit. In this paper, a veto analysis with an environmental monitor channel was implemented. We calculate the trigger rate of TAMA300 data and demonstrate the veto analysis using an alternative linear fit (ALF) filter. A threshold for the environmental monitor channel signals is set to be at 1% of the false dismissal rate. The result shows a 1/10-1/1000 reduction of trigger event rates

    Because organ transplantation relies on public support for donation, an analysis of public discourse around organ donation is essential. We investigated the portrayal of family veto - when a family overrides the deceased person's prior legally executed wishes to donate - in Canadian news media. Using the Canadian Newsstream database, we identified articles published in English-language newspapers addressing family veto between 2000 and 2016. Guided by the theoretical perspectives of framing of media effects, we conducted a systematic content analysis of the articles to examine how the Canadian media framed family veto. An initial in-depth analysis of the data set in which themes and patterns were captured and recorded identified coding categories, including primary framing of family veto, prevalence, reasons, ethical or legal concerns and overall tone of the article. Two coders analyzed the data set to ensure intercoder reliability. A total of 133 relevant articles were identified. Family veto was framed predominantly as something that should not be allowed (81 articles [60.9%]) and as a reality that is little understood outside the transplantation community (45 [33.8%]). One-quarter of the articles (32 [24.1%]) highlighted ethical principles of autonomy and justice associated with family veto. Family veto was represented as a stumbling block in the present organ donation system, with most publications (107 [80.4%]) calling for change. There were differing interpretations of organ donation legislation, with 82 articles (61.6%) erroneously stating or suggesting that existing legislation permits family veto. Family veto in organ donation was portrayed predominantly negatively. Many publications reflected a misunderstanding of the law concerning this issue. Although the framing of family veto highlighted important ethical and legal concerns as well as practice and policy considerations, research is needed to enhance the understanding of family veto in organ donation

  6. Item Vetoes and Attempts to Override Them in Multiparty Legislatures Vetos parciales e intentos de insistencia en legislaturas multipartidistas

    Full Text Available This paper analyzes the dynamics of vetoes and veto overrides in the context of a multiparty legislature using an original dataset from the period 1983–2007 in Argentina. We argue that the President can use an “item” or “partial” veto to selectively delete articles, while keeping enough distributive goods in the bill to break up the coalition responsible for its passage, thereby eliminating support for an override. Our research reveals that total vetoes – which affect all legislators equally – are more likely to be overridden than partial vetoes. Contradicting the received wisdom that in multiparty legislatures override attempts are more likely under a divided government, we find that override attempts are more likely in plurality governments. We use case analyses to illustrate the main arguments developed in this paper.El trabajo estudia las dinámicas desatadas por la práctica del veto presidencial e insistencias del congreso, en el contexto de legislaturas multipartidarias, a través del análisis de una base de datos original que abarca el período 1983-2007 en Argentina. El trabajo argumenta que el presidente puede usar el veto parcial para quitar del texto, en forma selectiva, artículos puntuales, dejando al mismo tiempo en el texto bienes distributivos suficientes como para romper la coalición responsable de la aprobación del proyecto, de manera tal de eliminar la posibilidad de una insistencia. La investigación revela que los vetos totales, que afectan por igual a todos los legisladores, son más factibles de ser insistidos que los vetos parciales. En contra de lo sostenido al momento acerca de que en legislaturas multipartidarias los intentos de insistencia son más factibles bajo gobierno dividido, este trabajo encuentra que son más factibles cuando el gobierno cuenta con al menos una pluralidad en una de las cámaras. Además del análisis cuantitativo, presentamos estudios de casos para ilustrar los argumentos

    To reduce the cosmic-ray-induced neutron background, we are testing a cosmic-ray veto option with a neutron detector system that uses plastic scintillator slabs mounted on the outside of a 3 He-tube detector. The scintillator slabs eliminate unwanted cosmic-ray events, enabling the detector to assay low-level plutonium samples, for which a low-background coincident signature is critical. This report describes the design and testing of the prototype cosmic-ray-veto detector system

  8. Impact of jet veto resummation on slepton searches

    2016-03-01

    Several searches for new physics at the LHC require a fixed number of signal jets, vetoing events with additional jets from QCD radiation. As the probed scale of new physics gets much larger than the jet-veto scale, such jet vetoes strongly impact the QCD perturbative series, causing nontrivial theoretical uncertainties. We consider slepton pair production with 0 signal jets, for which we perform the resummation of jet-veto logarithms and study its impact. Currently, the experimental exclusion limits take the jet-veto cut into account by extrapolating to the inclusive cross section using parton shower Monte Carlos. Our results indicate that the associated theoretical uncertainties can be large, and when taken into account have a sizeable impact already on present exclusion limits. This is improved by performing the resummation to higher order, which allows us to obtain accurate predictions even for high slepton masses. For the interpretation of the experimental results to benefit from improved theory predictions, it would be useful for the experimental analyses to also provide limits on the unfolded visible 0-jet cross section.

    The electric power sector reformulation implemented in the Brazil makes evident the intrinsic difficulty to handle with complex set of veto players. The multiplicity of veto players characterized by distinct ideologies results in the multiplication of business rounds related to the elaboration and implementation of the new game rules, whose agreement involves conflicts on the presented proposal, resulting in the slowness pf reformulation process conclusion.

  10. A Corporate Veto on Health Policy? Global Constitutionalism and Investor-State Dispute Settlement.

    Hawkins, Benjamin; Holden, Chris

    2016-10-01

    The importance of trade and investment agreements for health is now widely acknowledged in the literature, with much attention now focused on the impact of investor-state dispute settlement (ISDS) mechanisms. However, much of the analysis of such agreements in the health field remains largely descriptive. We theorize the implications of ISDS mechanisms for health policy by integrating the concept of global constitutionalism with veto point theory. It is argued that attempts to constitutionalize investment law, through a proliferation of International Investment Agreements (IIAs), has created a series of new veto points at which corporations may seek to block new policies aimed at protecting or enhancing public health. The multiplicity of new veto points in this global "spaghetti bowl" of IIAs creates opportunities for corporations to venue shop; that is, to exploit the agreements, and associated veto points, through which they are most likely to succeed in blocking or deterring new regulation. These concepts are illustrated with reference to two case studies of investor-state disputes involving a transnational tobacco company, but the implications of the analysis are of equal relevance for a range of other industries and health issues.

    Jet vetoes play an important role in many analyses at the LHC. Traditionally, jet vetoes have been imposed using a restriction on the transverse momentum p{sub Tj} of jets. Alternatively, one can also consider jet observables for which p{sub Tj} is weighted by a smooth function of the jet rapidity y{sub j} that vanishes as |y{sub j}|→∞. Such observables are useful as they provide a natural way to impose a tight veto on central jets but a looser one at forward rapidities. We consider two such rapidity-dependent jet veto observables, T{sub Bj} and T{sub Cj}, and compute the required beam and dijet soft functions for the jet-vetoed color-singlet production cross section at two loops. At this order, clustering effects from the jet algorithm become important. The dominant contributions are computed fully analytically while corrections that are subleading in the limit of small jet radii are expressed in terms of finite numerical integrals. Our results enable the full NNLL{sup ′} resummation and are an important step towards N{sup 3}LL resummation for cross sections with a T{sub Bj} or T{sub Cj} jet veto.

  12. The charged particle veto system of the cosmic ray electron synchrotron telescope

    Science.gov (United States)

    Geske, Matthew T.

    The Cosmic Ray Electron Synchrotron Telescope is a balloon-borne detector designed to measure cosmic electrons at energies from 2 to 50 TeV. CREST completed a successful 10-day Antarctic flight which launched on December 25, 2011. CREST utilizes a novel detection method, searching for the synchrotron radiation emitted by the interaction of TeV-energy electrons with the geomagnetic field. The main detector component for CREST is a 32 x 32 square array of BaF 2 crystal detectors coupled to photomultiplier tubes, with an inter-crystal spacing of 7.5 cm. This document describes the design, construction and flight of the CREST experiment. A special focus is put upon the charged particle veto system, and its use in the analysis of the CREST results. The veto system, consisting of a series of 27 large slabs of organic plastic scintillator read out through photomultiplier tubes, is designed as a passive mechanism for rejecting charged particle events that could contaminate the X-ray signal from synchrotron radiation. The CREST veto system has 99.15% geometric coverage, with individual detector components exhibiting a mean detection efficiency of 99.7%. In whole, the veto system provides a charged particle rejection factor of better than 7 x 103.

    Veto player theory generates predictions about governments' capacity for policy change. Due to the difficulty of identifying significant laws needed to change the policy status quo, evidence about governments' ability to change policy has been mostly provided for a limited number of reforms and single-country studies. To evaluate the predictive power of veto player theory for policy making across time, policy areas and countries, a dataset was gathered that incorporates about 5,600 important government reform measures in the areas of social, labour, economic and taxation policy undertaken in 13 Western European countries from the mid-1980s until the mid-2000s. Veto player theory is applied in a combined model with other central theoretical expectations on policy change derived from political economy (crisis-driven policy change) and partisan theory (ideology-driven policy change). Robust support is found that governments introduce more reform measures when economic conditions are poor and when the government is positioned further away from the policy status quo. No empirical support is found for predictions of veto player theory in its pure form, where no differentiation between government types is made. However, the findings provide support for the veto player theory in the special case of minimal winning cabinets, where the support of all government parties is sufficient (in contrast to minority cabinets) and necessary (in contrast to oversized cabinets) for policy change. In particular, it is found that in minimal winning cabinets the ideological distance between the extreme government parties significantly decreases the government's ability to introduce reforms. These findings improve our understanding of reform making in parliamentary democracies and highlight important issues and open questions for future applications and tests of the veto player theory.

    IceCube is the world's largest high-energy neutrino observatory, built at the geographic South Pole. For neutrino astronomy, a large background-free sample of well-reconstructed astrophysical neutrinos is essential. The main background for this signal are muons and neutrinos which are produced in cosmic-ray air showers in the Earth's atmosphere. The coincident detection of these air showers by the surface detector IceTop has been proven to be a powerful veto for atmospheric neutrinos and muons in the field of view of the southern hemisphere. This motivates a significant extension of IceTop. First estimates indicate that such a veto detector will more than double the discovery potential of current point source analyses. Here, we present the motivation and capabilities of different technologies based on simulations and measurements.

    Low background experiments need a suppression of cosmogenically induced events. The Gerda experiment located at Lngs is searching for the 0νββ decay of {sup 76}Ge. It is equipped with an active muon veto the main part of which is a water Cherenkov veto with 66 PMTs in the water tank surrounding the Gerda cryostat. With this system 806 live days have been recorded, 491 days were combined muon-germanium data. A muon detection efficiency of ε{sub μd} = (99.935 ± 0.015)% was found in a Monte Carlo simulation for the muons depositing energy in the germanium detectors. By examining coincident muon-germanium events a rejection efficiency of ε{sub μr} = (99.2{sub -0.4}{sup +0.3})% was found. Without veto condition the muons by themselves would cause a background index of BI{sub μ} = (3.16 ± 0.85) x 10{sup -3} cts/(keV . kg . year) at Q{sub ββ}. (orig.)

  20. IceVeto: Extended PeV neutrino astronomy in the Southern Hemisphere with IceCube

    2014-11-18

    IceCube, the world's largest high-energy neutrino observatory, built at the South Pole, recently reported evidence of an astrophysical neutrino flux extending to PeV energies in the Southern Hemisphere. This observation raises the question of how the sensitivity in this energy range could be further increased. In the down-going sector, in IceCube's case the Southern Hemisphere, backgrounds from atmospheric muons and neutrinos pose a challenge to the identification of an astrophysical neutrino flux. The IceCube analysis, that led to the evidence for astrophysical neutrinos, is based on an in-ice veto strategy for background rejection. One possibility available to IceCube is the concept of an extended surface detector, IceVeto, which could allow the rejection of a large fraction of atmospheric backgrounds, primarily for muons from cosmic ray (CR) air showers as well as from neutrinos in the same air showers. Building on the experience of IceTop/IceCube, possibly the most cost-effective and sensitive way to build IceVeto is as an extension of the IceTop detector, with simple photomultiplier based detector modules for CR air shower detection. Initial simulations and estimates indicate that such a veto detector will significantly increase the sensitivity to an astrophysical flux of ν{sub μ} induced muon tracks in the Southern Hemisphere compared to current analyses. Here we present the motivation and capabilities based on initial simulations. Conceptual ideas for a simplified surface array will be discussed briefly.

    The GERDA experiment searches for neutrinoless double beta decay (0νββ). To achieve a sensitivity of 10 -3 counts/(keVkgy) or better within a specific region of interest (ROI), a good background identification is needed. Therefore GERDA is located in the LNGS (Laboratori Nationali del Gran Sasso) underground facility. In addition to the good rejection of cosmic muons due to the surrounding bedrocks, a dual muon veto system has to be used. For calibration and monitoring of the muon veto, two separate systems have been developed.

    The GERDA experiment at LNGS of INFN is equipped with an active muon veto. The main part of the system is a water Cherenkov veto with 66 PMTs in the water tank surrounding the GERDA cryostat. The muon flux recorded by this veto shows a seasonal modulation. Two causes have been identified: (i) secondary muons from the CNGS neutrino beam (2.2%) and (ii) a temperature modulation of the atmosphere (1.4%). A mean cosmic muon rate of Iμ0 =(3.477 ± 0 .002stat ± 0 .067sys) ×10-4 /(s · m2) was found in good agreement with other experiments at LNGS. Combining the present result with those from previous experiments at LNGS the effective temperature coefficient αT , Lngs is determined to 0.93 ± 0.03. A fit of the temperature coefficients measured at various underground sites yields a kaon to pion ratio rK/π of 0.10 ± 0.03.

    The production of high-mass, color-singlet particles in hadron collisions is universally accompanied by initial state QCD radiation that is predominantly soft with respect to the hard process scale Q and/or collinear with respect to the beam axis. At TeV-scale colliders, this is in contrast to top quark and multijet processes, which are hard and central. Consequently, vetoing events with jets possessing transverse momenta above p{sub T}{sup Veto} in searches for new color-singlet states can efficiently reduce non-singlet backgrounds, thereby increasing experimental sensitivity. To quantify this generic observation, we investigate the production and leptonic decay of a Sequential Standard Model W{sup ′} boson at the 13 TeV Large Hadron Collider. We systematically consider signal and background processes at next-to-leading-order (NLO) in QCD with parton shower (PS) matching. For color-singlet signal and background channels, we resum Sudakov logarithms of the form α{sub s}{sup j}(p{sub T}{sup Veto})log{sup k} (Q/p{sub T}{sup Veto}) up to next-to-next-to-leading logarithmic accuracy (NNLL) with NLO matching. We obtain our results using the MADGRAPH5{sub A}MC@NLO and MADGRAPH5{sub A}MC@NLO-SCET frameworks, respectively. Associated Universal FEYNRULES Output model files capable of handling NLO+PS- and NLO+NNLL-accurate computations are publicly available. We find that within their given uncertainties, both the NLO+PS and NLO+NNLL(veto) calculations give accurate and consistent predictions. Consequently, jet vetoes applied to color-singlet processes can be reliably modeled at the NLO+PS level. With respect to a b-jet veto of p{sub T}{sup Veto}=30 GeV, flavor-agnostic jet vetoes of p{sub T}{sup Veto}=30−40 GeV can further reduce single top and tt̄ rates by a factor of 2-50 at a mild cost of the signal rate. Jet vetoes can increase the signal-to-noise ratios by roughly 10% for light W{sup ′} boson masses of 30−50 GeV and 25%-250% for masses of 300-800 GeV.

    2012-01-01

    Cosmic radiation contributes significantly towards the background radiation measured by a gamma-spectrometer. A novel cosmic veto gamma-spectrometer has been developed that provides a mean background reduction of 54.5%. The system consists of plastic scintillation plates operated in time-stamp mode to detect coincident muon interactions within an HPGe gamma-spectrometer. The instrument is easily configurable and provides improved sensitivity for radionuclides indicative of nuclear weapons tests and reactor incidents, including 140 Ba, 95 Zr, 99 Mo, 141 Ce, 147 Nd, 131 I, 134 Cs and 137 Cs. This has been demonstrated for Comprehensive Nuclear-Test-Ban Treaty applications to obtain the required 140 Ba MDA of 24 mBq within 2 days counting. Analysis of an air filter sample collected during the Fukushima incident indicates improved sensitivity compared to conventional gamma-spectrometers. (author)

    Full Text Available O trabalho propõe-se a demonstrar porque desde 1979 foi possível aos militares brasileiros atuarem como veto players sempre que entrou em debate a revisão da Lei de Anistia. Nossa hipótese é que esse poder de veto explica-se pela existência de uma grande autonomia militar antes, durante e depois da ditadura, associada aos baixos níveis de respeito aos direitos humanos na sociedade brasileira e ao baixo interesse do Congresso e do governo em geral pelo tema das Forças Armadas.The study aims to show why since 1979 the Brazilian military had been able to act as veto players whenever the debate about Amnesty Law was argued. Our hypothesis is that this veto power is explained by the existence of a large military autonomy before, during and after the dictatorship, associated with low levels of human rights culture in Brazilian society and the low interest of Congress and government in general about Armed Forces issues.

    The Dortmund Low Background Facility (DLB) is a low-background gamma-ray spectrometry system with an artificial overburden built at ground level. It uses a high-purity germanium detector with a relative efficiency of 60 %, which is set up inside a massive shielding. The outer shielding consists of barite concrete and cast iron, corresponding to ten meters of water equivalent (mw.e.), and houses a multi-layer lead castle as an inner shielding, that features borated polyethylene as a neutron absorber. Additionally an active muon veto is installed to reduce cosmic-induced contributions to the spectrum. The remarkably lowered background of the DLB compared to an unshielded spectrometer, allows radio-purity screening measurements for material preselection with sensitivities better than 1 Bq/kg. This talk focusses on the muon veto of the DLB. Its basic concept and its benefits for low-background operation are described. Also its current status of development and future upgrade plans are presented.

To reach the aspired background index of ≤ 10{sup -3} cts/(keV.kg.yr) for Phase II active background-suppression techniques are applied, including an active liquid argon (LAr) veto. It has been demonstrated with the LArGe test facility that the detection of argon scintillation light can be used to effectively suppress background events in the germanium, which simultaneously deposit energy in the LAr. The light instrumentation consisting of photomultiplier tubes (PMT) and wavelength-shifting fibers connected to silicon multipliers (SiPM) has been installed in Gerda. In this talk the low background design of the LAr veto and its performance during the commissioning runs are reported.

    Gerda is an experiment to search for the neutrinoless double beta decay of {sup 76}Ge. Results of Phase I have been published in summer 2013. Currently Gerda is being upgraded to a second phase. To reach the aspired background index of ≤ 10{sup -3} cts/(keV . kg . yr) for Phase II active background-suppression techniques will be applied, including an active liquid argon veto (LAr veto). It has been demonstrated by the LArGe test facility that the detection of argon scintillation light can be used to effectively suppress background events in the germanium, which simultaneously deposit energy in LAr. This talk focusses on the light instrumentation which is being installed in GERDA. Photomultiplier tubes (PMT) and wavelength-shifting fibers connected to silicon photomultipliers (SiPM) are combined to maximize the photoelectron-yield with respect to various background sources. Monte Carlo simulations have been performed to optimize the design for background suppression and low self-induced background. First results of the prototypes and the progress of installation are reported.

    The NA62 experiment at CERN SPS aims at measuring-100 events of the very rare decay K+ →π +ννˉ (BR∼8.5xlO∼10). It poses stringent requirements on PID capabilities to reject the overwhelming π+π0 (63%) and Kμ2(21%) backgrounds. The photon veto system must provide a rejection factor of 10∼8 on π0 decays. As a main γ veto detector, the NA48 liquid Kripton calorimeter will be used. To have full geometrical acceptance up to 50 mr, a set of 12 veto stations should be placed along the vacuum decay tank, with an inefficiency <10∼4 in a wide energy range (200 MeV-35 GeV). Good energy resolution (∼10% at 1 GeV) for threshold definition, good time resolution (∼1 ns) to be used at the trigger level, sensitivity to MIP for calibration with muons of the beam halo are needed. A moderate segmentation in the azimuthal angle is desirable, for reducing the counting rate and providing information on the γ direction. We performed an intense R&D program on three solutions: “spaghetti” calorimeter...

    IceCube is a neutrino observatory located at the geographic South Pole. The main backgrounds for IceCube's primary goal, the measurement of astrophysical neutrinos, are muons and neutrinos from cosmic-ray air showers in the Earth's atmosphere. Strong supression of these backgrounds from the Southern hemisphere has been demonstrated by coincident detection of these air showers with the IceTop surface detector. For an extended instrument, IceCube-Gen2, it is considered to build an enlarged surface array, IceVeto, that will improve the detection capabilities of coincident air showers. We will present simulation studies to estimate the IceVeto capabilities to optimize the IceCube-Gen2 design.

  19. Correlated seed failure as an environmental veto to synchronize reproduction of masting plants.

    2018-07-01

    Variable, synchronized seed production, called masting, is a widespread reproductive strategy in plants. Resource dynamics, pollination success, and, as described here, environmental veto are possible proximate mechanisms driving masting. We explored the environmental veto hypothesis, which assumes that reproductive synchrony is driven by external factors preventing reproduction in some years, by extending the resource budget model of masting with correlated reproductive failure. We ran this model across its parameter space to explore how key parameters interact to drive seeding dynamics. Next, we parameterized the model based on 16 yr of seed production data for populations of red (Quercus rubra) and white (Quercus alba) oaks. We used these empirical models to simulate seeding dynamics, and compared simulated time series with patterns observed in the field. Simulations showed that resource dynamics and reproduction failure can produce masting even in the absence of pollen coupling. In concordance with this, in both oaks, among-year variation in resource gain and correlated reproductive failure were necessary and sufficient to reproduce masting, whereas pollen coupling, although present, was not necessary. Reproductive failure caused by environmental veto may drive large-scale synchronization without density-dependent pollen limitation. Reproduction-inhibiting weather events are prevalent in ecosystems, making described mechanisms likely to operate in many systems. © 2018 The Authors New Phytologist © 2018 New Phytologist Trust.

    IceTop is an air-shower detector located at the South Pole on the surface above the IceCube detector. It consists of 81 detector stations with two Cherenkov tanks each. The tanks are filled with clear ice and instrumented with two photomultipliers. IceTop detects cosmic-ray induced air-showers above an energy threshold of ∝300 TeV. Muons and neutrinos from these air-showers are the main background for astrophysical neutrino searches with IceCube. The usage of IceTop to veto air-showers largely reduces this background in the field of view. To enlarge the field of view an extension of the surface detector, IceVeto, is planned. Therefore, we investigate the properties of an original IceTop tank as a laboratory reference for the development of new detection module designs. First results of these measurements are presented.

  1. Advance commitment: an alternative approach to the family veto problem in organ procurement.

    Science.gov (United States)

    De Wispelaere, Jurgen; Stirton, Lindsay

    2010-03-01

    This article tackles the current deficit in the supply of cadaveric organs by addressing the family veto in organ donation. The authors believe that the family veto matters-ethically as well as practically-and that policies that completely disregard the views of the family in this decision are likely to be counterproductive. Instead, this paper proposes to engage directly with the most important reasons why families often object to the removal of the organs of a loved one who has signed up to the donor registry-notably a failure to understand fully and deliberate on the information and a reluctance to deal with this sort of decision at an emotionally distressing time. To accommodate these concerns it is proposed to separate radically the process of information, deliberation and agreement about the harvesting of a potential donor's organs from the event of death and bereavement through a scheme of advance commitment. This paper briefly sets out the proposal and discusses in some detail its design as well as what is believed to be the main advantages compared with the leading alternatives.

  2. Finite top-mass effects in gluon-induced Higgs production with a jet-veto at NNLO

    Effects from a finite top quark mass on the H+n-jet cross section through gluon fusion are studied for n = 0/n ≥ 1 at NNLO/NLO QCD. For this purpose, sub-leading terms in 1/m{sub t} are calculated. We show that the asymptotic expansion of the jet-vetoed cross section at NNLO is very well behaved and that the heavy-top approximation is valid at the five permille level up to jet-veto cuts of 300 GeV. For the inclusive Higgs+jet rate, we introduce a matching procedure that allows for a reliable prediction of the top-mass effects using the expansion in 1/m{sub t}. The quality of the effective field theory to evaluate differential K-factors for the distribution of the hardest jet is found to be better than 1-2% as long as the transverse momentum of the jet is integrated out or remains below about 150 GeV.

  3. Coherent network detection of gravitational waves: the redundancy veto

    International Nuclear Information System (INIS)

    Wen Linqing; Schutz, Bernard F

    2005-01-01

    A network of gravitational wave detectors is called redundant if, given the direction to a source, the strain induced by a gravitational wave in one or more of the detectors can be fully expressed in terms of the strain induced in others in the network. Because gravitational waves have only two polarizations, any network of three or more differently oriented interferometers with similar observing bands is redundant. The three-armed LISA space interferometer has three outputs that are redundant at low frequencies. The two aligned LIGO interferometers at Hanford WA are redundant, and the LIGO detector at Livingston LA is nearly redundant with either of the Hanford detectors. Redundant networks have a powerful veto against spurious noise, a linear combination of the detector outputs that contains no gravitational wave signal. For LISA, this 'null' output is known as the Sagnac mode, and its use in discriminating between detector noise and a cosmological gravitational wave background is well understood. But the usefulness of the null veto for ground-based detector networks has been ignored until now. We show that it should make it possible to discriminate in a model-independent way between real gravitational waves and accidentally coincident non-Gaussian noise 'events' in redundant networks of two or more broadband detectors. It has been shown that with three detectors, the null output can even be used to locate the direction to the source, and then two other linear combinations of detector outputs give the optimal 'coherent' reconstruction of the two polarization components of the signal. We discuss briefly the implementation of such a detection strategy in realistic networks, where signals are weak, detector calibration is a significant uncertainty, and the various detectors may have different (but overlapping) observing bands

  4. Prolonged minor allograft survival in intravenously primed mice--a test of the veto hypothesis

    Experiments were performed to test the hypothesis that veto cells are responsible for the prolonged survival of minor allografts of skin that is observed in recipients primed intravenously with spleen cells from mice syngeneic with the skin donors. This prolonged survival was observed for each of several minor histocompatibility (H) antigens and is antigen-specific. Gamma radiation (3300 rads) abolished the ability of male spleen cells infused i.v. to delay the rejection of male skin grafts (H-Y antigen) on female recipients. However, depletion of Thy-1+ cells from the i.v. infusion failed to abolish the ability to prolong male skin graft survival. Furthermore, the prolonged survival accorded to B6 (H-2b) male skin grafts on CB6F1 (H-2b/H-2d) female recipients given i.v. infusions of B6 male spleen cells extended to BALB/c (H-2d) male skin grafts as well, indicating a lack of MHC restriction. Thus, prolongation of minor allograft survival by i.v. infusion of minor H antigen-bearing spleen cells appears not to depend on veto T cells that others have found to be responsible for the suppression of CTL generation

    A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20 GeV is found between the two boundary jets. The fraction of dijet events that survive the jet veto is presented for boundary jets that are separated by up to six units of rapidity and with mean transverse momentum 50 < pT(avg) < 500 GeV. The mean multiplicity of jets above the veto scale in the rapidity interval bounded by the dijet system is also presented as an alternative method for quantifying perturbative QCD emission. The data are compared to a next-to-leading order plus parton shower prediction from the POWHEG-BOX, an all-order resummation using the HEJ calculation and the PYTHIA, HERWIG++ and ALPGEN event generators. The measurement was performed using pp collisions at sqrt(s)=7 TeV using data recorded by the ATLAS detector in 2010.

    A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20 GeV is found between the two boundary jets. The fraction of dijet events that survive the jet veto is presented for boundary jets that are separated by up to six units of rapidity and with mean transverse momentum 50 < p¯T < 500 GeV. The mean multiplicity of jets above the veto scale in the rapidity interval bounded by the dijet system is also presented as an alternative method for quantifying perturbative QCD emission. The data are compared to a next-to-leading order plus parton shower prediction from the powheg-box, an all-order resummation using the hej calculation and the pythia, herwig++ and alpgen event generators. The measurement was performed using pp collisions at √s=7 TeV using data recorded by the ATLAS detector in 2010.

    The Dortmund Low Background HPGe Facility (DLB) is a germanium facility with heavy shielding located above ground. It's primary task is to provide material screening support for the COBRA experiment which was built to search for neutrinoless double beta decay. Germanium detectors used for low background gamma spectroscopy are usually operated under either a fairly low overburden (O(1m) water equivalent (mwe)) or high overburden, e.g. in specialised underground laboratories (O(>100 mwe)). In between, only a few facilities exist, such as the DLB. The artificial overburden of 10 mwe already shields the weak component of cosmic rays. The lead castle with a state-of-the-art neutron shielding as well as the active anti-cosmics veto detector enable low background gamma spectrometry with the advantage of good accessibility on the university campus. Throughout the last years improvements have been made especially on the cosmics veto and the MC simulation leading to an remarkable low integral background counting rate (40-2700 keV) of about 2.5228(52) counts/kg/min. The talk summarises the completed tasks and presents the current status.

    The Crystal Clear Collaboration (CCC) has built a prototype of a novel positron emission tomograph dedicated to functional breast imaging, the ClearPEM. The ClearPEM uses the common radio pharmaceutical FDG for imaging cancer. As FDG is a rather non-specific radio tracer, it accumulates not only in cancer cells but in all cells with a high energy consumption, such as the heart and liver. This fact poses a problem especially in breast imaging, where the vicinity of the heart and other organs to the breast leads to a high background noise level in the scanner. In this work, a veto counter to reduce the background is described. Different configurations and their effectiveness were studied using the GATE simulation package.

    An active veto system consisting of plastic scintillation panels was installed outside the Pb shielding of a 115% n-type HPGe detector in an effort to reduce background continuum generated by cosmic ray muons on the surface. The Low Background Facility at the Lawrence Berkeley National Laboratory performs low level assay (generally of primordial U, Th, K) of candidate construction materials for experiments that require a high level of radiopurity. The counting is performed in two facilities: one local surface site and a remote underground site of approximately 600 m.w.e. For the recently installed veto system at the surface location, the top scintillator panel has been in use for nearly 1 year and the full 3π anticoincidence shield was commissioned into normal counting operations in January 2013. The integrated background from 20 to 3600 keV is reduced overall by a factor of 8, where most of the energy spectrum above 100 keV achieves an overall reduction that varies from 8 to 10. A dramatic improvement of peak-to-background across the entire continuum is observed, greatly enhancing low-level peaks that would otherwise be obscured.

    The GERmanium Detector Array (Gerda) is a experiment searching for the neutrinoless double beta decay of {sup 76}Ge. This very rare weakly interacting process is predicted to occur if the neutrino exhibits a mass and is a Majorana particle; i.e. it is its own antiparticle. Although the double beta decay with emission of two neutrinos has been found in several nuclei, there is at this moment only a part of the Heidelberg-Moscow Collaboration claiming to have observed the neutrinoless double beta decay. The best limit for the half life currently is T{sub 1/2} > 1.2.10{sup 25} y. Gerda will expose about 15 kg.y of enriched germanium detectors from the Heidelberg-Moscow and IGEX crystals in phase I. In this phase, it will be able to test the claim within one year, due to reduced background by a factor 10. In phase II about 100 kg.y of data will be accumulated, leading to T{sub 1/2} > 2.10{sup 26} y due to an additional reduction of the background by a factor of 10. For a high sensitivity at these half lives, it is necessary to detect the corresponding rare events. Therefore background reduction to a rate of 10{sup -3} (counts)/(keV.kg.year) is of utmost importance. Therefore different background identification methods, like pulseshape analysis or a muon veto will be used. In this work, the development of the Cherenkov muon veto detectors is presented. First design studies will be shown, including extensive Monte-Carlo simulations. These simulations were also used to optimize the trigger conditions of the data acquisition, to detect all muons, that cause an energy deposition in the germanium detectors. Finally the on site construction at the Laboratori Nazionali del Gran Sasso in Italy will be described. (orig.)

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is supported by a network of certified laboratories that perform high-resolution gamma-spectrometry on global air filter samples for the identification of 85 radionuclides. At the UK CTBT Radionuclide Laboratory (GBL15), a novel cosmic veto gamma-spectrometer has been developed to improve the sensitivity of measurements for treaty compliance. The system consists of plastic scintillation plates operated in time-stamp mode to detect coincident cosmic-ray interactions within an HPGe gamma-spectrometer. This provides a mean background reduction of 75.2 % with MDA improvements of 45.6 %. The CTBT requirement for a 140 Ba MDA is achievable after 1.5 days counting compared to 5-7 days using conventional systems. The system does not require dedicated coincidence electronics, and remains easily configurable with dual acquisition of unsuppressed and suppressed spectra. Performance has been significantly improved by complete processing of the cosmic-ray spectrum (0-25 MeV) combined with the Canberra Lynx TM multi-channel analyser. The improved sensitivity has been demonstrated for a CTBT air filter sample collected after the Fukushima incident. (author)

    We report the first measurement of the total muon flux underground at the Davis Campus of the Sanford Underground Research Facility at the 4850 ft level. Measurements were performed using the MAJORANADEMONSTRATOR muon veto system arranged in two different configurations. The measured total flux is (5.31 ± 0.17) ×10-9 μ /s/cm2. Demonstrate a path forward to achieving a background rate at or below 1 count/(ROI-t-y)in the 4-keV region of interest (ROI) around the 2039-keV Q-value for 76Ge ββ(0ν) decay. This is required for tonne-scale germanium-based searches that will probe the inverted-ordering neutrino-mass parameter space for the effective Majorana neutrino mass in ββ(0ν) decay. Show technical and engineering scalability toward a tonne-scale instrument. Perform searches for additional physics beyond the Standard Model, such as dark matter and axions. The MAJORANA Collaboration has designed a modular instrument composed of two cryostats built from ultra-pure electroformed copper, with each cryostat capable of housing over 20 kg of HPGe detectors. The MAJORANADEMONSTRATOR contains 30 kg of detectors fabricated from Ge material enriched to 88% in 76Ge and another 15 kg fabricated from natural Ge (7.8% 76Ge). The modular approach allows us to assemble and optimize each cryostat independently, providing a fast deployment with minimal effect on already-operational detectors.Starting from the innermost cavity, the cryostats are surrounded by a compact graded shield composed of an inner layer of electroformed copper, a layer of commercially sourced C10100 copper, high-purity lead, an active muon veto, borated polyethylene, and pure polyethylene shielding. The cryostats, copper, and lead shielding are enclosed in a radon exclusion box and rest on an over-floor table that has openings for the active muon veto and polyethylene shielding panels situated below the detector. The entire experiment is located in a clean room at the 4850 ft level of SURF. A high

    An estimated 2.4 billion people lack access to improved sanitation which has devastating consequences for human health and the environment. Understanding what constitute sanitation demand is crucial for accelerating the spread of improved sanitation. This study aims to understand the adoption mechanisms for improved sanitation. An informal peri-urban settlement in Cochabamba, Bolivia was selected as a case study to understand adoption patterns. Various qualitative methods of data collection and analysis were employed. The findings showed that pour-flush toilets was the only preferred sanitation alternative at the study site. An adoption framework for waterborne toilets was developed based on diffusion of innovation theory. Factors that influence adoption were identified. Some functioned as triggers and initiated adoption, whereas some factors blocked adoption and constituted veto-barriers. Most factors were connected to the individual household situation and its members, but neighborhood development also affected pour-flush adoption. Based on adoption time the residents were divided into the following adoption groups: first adopters, early majority, late majority, laggards and non-adopters. Each adoption group followed its own adoption route with specific characteristics and respective triggers or veto-barriers. We argue that the strong demand for waterborne toilets in peri-urban areas need to be recognized and the developed framework could be used for customizing sanitation improvement programs for certain target groups.

    A measurement of the jet activity in ttbar events produced in proton-proton collisions at a centre-of-mass energy of 7 TeV is presented, using 2.05 fb^-1 of integrated luminosity collected by the ATLAS detector at the Large Hadron Collider. The ttbar events are selected in the dilepton decay channel with two identified b-jets from the top quark decays. Events are vetoed if they contain an additional jet with transverse momentum above a threshold in a central rapidity interval. The fraction of events surviving the jet veto is presented as a function of this threshold for four different central rapidity interval definitions. An alternate measurement is also performed, in which events are vetoed if the scalar transverse momentum sum of the additional jets in each rapidity interval is above a threshold. In both measurements, the data are corrected for detector effects and compared to the theoretical models implemented in MC@NLO, POWHEG, ALPGEN and SHERPA. The experimental uncertainties are often smaller than the ...

  17. The experiment 787 high efficiency photon veto detector in the 20 - 300 MEV range

    Experiment E787 is searching for the rare decay K → πνν at the Brookhaven Alternating Gradient Synchrotron (AGS). To suppress the background from the dominant K → ππ o branch, a fast lead scintillator sandwich veto assembly system was used. An inefficiency level of ∼ 1 x 10 -6 has been achieved for detecting π o . The limitations are in part geometrical in part due to photonuclear interactions. Our present understanding of these limitations will be presented together with our upgrading plans using pure CSI crystals. (author). 7 refs., 4 figs

  18. Taking a non-conflicting approach to the siting of a deep geological repository or Why introducing the right of 'veto' for the affected municipalities is not a good solution

    2012-01-01

    Various communities, especially ecological initiatives, demand that municipalities affected by planned siting of a Czech deep geological repository for the disposal of spent nuclear fuel and radioactive wastes be given the right to veto such plans. It is shown that the legal tools available to municipalities for defending their legitimate interests within the current siting licensing procedure are sufficient and that the introduction of the right of veto into the Czech law would be a non-conceptual and unprecedented intervention into existing juridical and procedural institutes.

  19. Characterization of the liquid argon veto of the GERDA experiment and its application for the measurement of the "7"6Ge half-life

    The search for neutrinoless double-beta decay (0νββ) is one of the most active fields in modern particle physics as the observation of this process would prove lepton number violation and imply new physics beyond the Standard Model of particle physics. The GERDA experiment searches for this decay by operating bare Germanium detectors, enriched in the ββ isotope "7"6Ge, in liquid argon. For the first time, a ββ-experiment combines the excellent properties of semiconductor Germanium detectors with an active background suppression technique based on the simultaneous detection of liquid argon scintillation light by photomultiplier tubes and silicon photomultipliers coupled to scintillating fibers (LAr veto). The LAr veto has been successfully operated during the first six months of Phase II of the experiment and yielded - in combination with a Germanium detector pulse shape discrimination technique - a background index of (0.7"+"1"."1_-_0_._5).10"-"3 ((cts)/(kg.keV.yr)). With an ultimate exposure of 100 kg.yr this will allow for a 0νββ-decay half-life sensitivity of the Gerda Phase II experiment of 10"2"6 yr. Double-beta decay under the emission of two neutrinos (2νββ) is a second-order process but which is allowed by the Standard Model. The excellent background reduction of the LAr veto results in an unprecedented signal-to-background ratio of 30:1 in the energy region dominated by 2νββ-decay of "7"6Ge. The remaining background after LAr veto is estimated using the suppression factor from calibration source measurements and results in a measurement of T"2"ν_1_/_2=(1.98±0.02(stat)±0.05(syst)).10"2"1 yr and T_1_/_2"2"ν=(1.92 ±0.02(stat)±0.11(syst)).10"2"1 yr based on two different detector designs and give uncertainties on the detector parameters but both with improved systematic uncertainties in comparison to earlier measurements.

  1. Vetos y resistencias en el fracaso de la reforma de la planta local en España

    Directory of Open Access Journals (Sweden)

    Full Text Available La Ley de Racionalización y Sostenibilidad de la Administración Local de 27 de diciembre de 2013 ha sido el último intento legislativo de profunda incidencia sobre la organización de la planta local en España. Una Ley nacida sin consenso y que ha fracasado en sus objetivos. Este artículo quiere hacer, desde el punto de vista de la política un análisis de las causas de ese fracaso. Según indican algunos autores como Alba y Navarro «la literatura más relevante del gobierno local en España proviene de estudiosos del Derecho Administrativo altamente orientada al marco jurídico, la posición jurídica de la unidad local de gobierno y las cuestiones relacionadas con los procedimientos legales». La Ley nace de una necesidad impuesta por la Unión Europea para controlar el déficit de la administración local, nace sin consenso, y fracasa en el intento de reducir la planta local. Este último resultado es del máximo interés porque puede observarse dentro de un marco comparativo entre modelos en Europa.

  3. El derecho de veto en el Consejo de Seguridad de Naciones Unidas: la historia de la válvula de seguridad que paralizó el sistema

    Directory of Open Access Journals (Sweden)

    María Isabel Torres Cazorla

    2008-10-01

    Full Text Available Este artículo pretende realizar un análisis del derecho de veto en el Consejo de Seguridad de Naciones Unidas, comenzando por sus orígenes y las razones que motivaron su creación, para estudiar posteriormente el uso y en múltiples ocasiones el que cabría calificar como “abuso” en la utilización de este privilegio por parte de algunos de los miembros permanentes del Consejo de Seguridad. Dado que la mayor parte de los trabajos doctrinales que tratan de esta cuestión datan de hace varias décadas, resulta de sumo interés realizar un análisis del derecho de veto desde que la organización comenzó su andadura, hasta el momento actual.

  4. The NA62 rare Kaon decay experiment Photon Veto System

    International Nuclear Information System (INIS)

    Perfetto, F.

    2009-01-01

    The NA62 experiment at CERN SPS is aimed at measuring the rare decay K + →π + νν-bar. This poses very stringent requirements on the particle identification capabilities of the apparatus in order to reject the overwhelming K + →μ + ν and K + →π + π 0 background. In particular, a π 0 rejection at level of 10 -8 is needed to complement the kinematical rejection of π + π 0 events. In order to have a full acceptance from 0 to 50 mrad, partly covered by NA48 liquid Kripton calorimeter, a set of veto anti-counters should be placed along the vacuum decay tank, to catch large angle photons with a detection efficiency better than 10 -4 in a wide energy range: from few hundreds MeV to 35 GeV. Intense R and D programs have been carried out in order to study different technological solutions: a lead-scintillating fibers calorimeter, lead-scintillator sandwich calorimeter and finally an original re-use of the existing barrel of the OPAL lead-glass electromagnetic calorimeter. We present the results on detector performances and compare the three solutions.

  5. Used percentage veto for LIGO and virgo binary inspiral searches

    A challenge for ground-based gravitational wave detectors such as LIGO and Virgo is to understand the origin of non-astrophysical transients that contribute to the background noise, obscuring real astrophysically produced signals. To help this effort, there are a number of environmental and instrumental sensors around the site, recording data in 'channels'. We developed a method called the used percentage veto to eliminate corrupted data based on the statistical correlation between transients in the gravitational wave channel and in the auxiliary channels. The results are used to improve inspiral binary searches on LIGO and Virgo data. We also developed a way to apply this method to help find the physical origin of such transients for detector characterization. After identifying statistically correlated channels, a follow-up code clusters coincident events between the gravitational wave channel and auxiliary channels, and thereby classifies noise by correlated channels. For each selected event, the code also gathers and creates information that is helpful for further investigations. The method is contributing to identifying problems and improving data quality for the LIGO S6 and Virgo VSR2 science runs.

  6. Cosmic veto gamma-spectrometry for Comprehensive Nuclear-Test-Ban Treaty samples

    Burnett, J.L.; Davies, A.V.

    2014-01-01

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is supported by a global network of monitoring stations that perform high-resolution gamma-spectrometry on air filter samples for the identification of 85 radionuclides. At the UK CTBT Radionuclide Laboratory (GBL15), a novel cosmic veto gamma-spectrometer has been developed to improve the sensitivity of station measurements, providing a mean background reduction of 80.8% with mean MDA improvements of 45.6%. The CTBT laboratory requirement for a 140 Ba MDA is achievable after 1.5 days counting compared to 5–7 days using conventional systems. The system consists of plastic scintillation plates that detect coincident cosmic-ray interactions within an HPGe gamma-spectrometer using the Canberra Lynx TM multi-channel analyser. The detector is remotely configurable using a TCP/IP interface and requires no dedicated coincidence electronics. It would be especially useful in preventing false-positives at remote station locations (e.g. Halley, Antarctica) where sample transfer to certified laboratories is logistically difficult. The improved sensitivity has been demonstrated for a CTBT air filter sample collected after the Fukushima incident

    This paper focuses on veto supertree methods; i.e., methods that aim at producing a conservative synthesis of the relationships agreed upon by all source trees. We propose desirable properties that a supertree should satisfy in this framework, namely the non-contradiction property (PC) and the induction property (PI). The former requires that the supertree does not contain relationships that contradict one or a combination of the source topologies, whereas the latter requires that all topological information contained in the supertree is present in a source tree or collectively induced by several source trees. We provide simple examples to illustrate their relevance and that allow a comparison with previously advocated properties. We show that these properties can be checked in polynomial time for any given rooted supertree. Moreover, we introduce the PhySIC method (PHYlogenetic Signal with Induction and non-Contradiction). For k input trees spanning a set of n taxa, this method produces a supertree that satisfies the above-mentioned properties in O(kn(3) + n(4)) computing time. The polytomies of the produced supertree are also tagged by labels indicating areas of conflict as well as those with insufficient overlap. As a whole, PhySIC enables the user to quickly summarize consensual information of a set of trees and localize groups of taxa for which the data require consolidation. Lastly, we illustrate the behaviour of PhySIC on primate data sets of various sizes, and propose a supertree covering 95% of all primate extant genera. The PhySIC algorithm is available at http://atgc.lirmm.fr/cgi-bin/PhySIC.

    Comparison of neutrons and protons emitted in heavy ion collisions is one of the observables to probe symmetry energy, which is related to the properties of neutron star. In general, neutrons are difficult to measure and neutron detectors are not as easy to use or as widely available as charged particle detectors. Two neutron walls (NW) called LANA exist at the National Superconducting Cyclotron Laboratory. Although the NSCL NW attains excellent discrimination of γ rays and neutron, it fails to discriminate charged particles from neutrons. To ensure near 100% rejection of charged particles, a Charged Particle Veto Wall (VW) is being jointly built by Michigan State University and Western Michigan University. It will be placed in front of one NW. To increase efficiency in detecting neutrons, the second neutron wall is stacked behind it. In this presentation, I will discuss the design, construction and testing of the VW together with the LANA in preparation of two approved NSCL experiments to probe the density and momentum dependence of the symmetry energy potentials in the equation state of the asymmetric nuclear matter. This material is based upon work supported by the National Science Foundation under Grant No. PHY 1565546.

    To enable complete rejection of holder-related events in the upcoming CRESST-III dark matter search experiment, the scintillating target crystals are held by calcium tungstate sticks (iSticks) instrumented with tungsten transition edge sensors (TESs). Since the iStick signals are used exclusively for vetoing, it is sufficient to register if an event happened in any stick, without knowing which one. This allows the operation of all iSticks in a single readout circuit, requiring just one SQUID magnetometer. The talk describes the effect of bias current heating and corresponding hysteresis phenomena known in single-TES circuits, and the resulting conditions for stability in multiple-TES circuits. The fundamentally different behaviour of parallel and series circuits and resulting design choices are explored.

    We report the performance of an active veto system using a liquid scintillator with NaI(Tl) crystals for use in a dark matter search experiment. When a NaI(Tl) crystal is immersed in the prototype detector, the detector tags 48% of the internal {sup 40}K background in the 0–10 keV energy region. We also determined the tagging efficiency for events at 6–20 keV as 26.5±1.7% of the total events, which corresponds to 0.76±0.04 events/keV/kg/day. According to a simulation, approximately 60% of the background events from U, Th, and K radioisotopes in photomultiplier tubes are tagged at energies of 0–10 keV. Full shielding with a 40-cm-thick liquid scintillator can increase the tagging efficiency for both the internal {sup 40}K and external background to approximately 80%.

    The Ricochet experiment seeks to measure Coherent (neutral-current) Elastic Neutrino-Nucleus Scattering (CE νNS) using metallic superconducting and germanium semi-conducting detectors with sub-keV thresholds placed near a neutrino source such as the Chooz Nuclear Reactor Complex. In this poster, we present an estimate of the flux of cosmic-ray induced neutrons, which represent an important background in any (CE νNS) search, based on reconstructed cosmic ray data from the Chooz Site. We have simulated a possible Ricochet deployment at the Chooz site in GEANT4 focusing on the spallation neutrons generated when cosmic rays interact with the water tank veto that would surround our detector. We further simulate and discuss the effectiveness of various shielding configurations for optimizing the background levels for a future Ricochet deployment.

    The first observing run of Advanced LIGO spanned 4 months, from 12 September 2015 to 19 January 2016, during which gravitational waves were directly detected from two binary black hole systems, namely GW150914 and GW151226. Confident detection of gravitational waves requires an understanding of instrumental transients and artifacts that can reduce the sensitivity of a search. Studies of the quality of the detector data yield insights into the cause of instrumental artifacts and data quality vetoes specific to a search are produced to mitigate the effects of problematic data. In this paper, the systematic removal of noisy data from analysis time is shown to improve the sensitivity of searches for compact binary coalescences. The output of the PyCBC pipeline, which is a python-based code package used to search for gravitational wave signals from compact binary coalescences, is used as a metric for improvement. GW150914 was a loud enough signal that removing noisy data did not improve its significance. However, the removal of data with excess noise decreased the false alarm rate of GW151226 by more than two orders of magnitude, from 1 in 770 yr to less than 1 in 186 000 yr.

    To quantify the potential impact of the Integrating the Healthcare Enterprise-Radiation Oncology Quality Assurance with Plan Veto (QAPV) on patient safety of external beam radiation therapy (RT) operations. An institutional database of events (errors and near-misses) was used to evaluate the ability of QAPV to prevent clinically observed events. We analyzed reported events that were related to Digital Imaging and Communications in Medicine RT plan parameter inconsistencies between the intended treatment (on the treatment planning system) and the delivered treatment (on the treatment machine). Critical Digital Imaging and Communications in Medicine RT plan parameters were identified. Each event was scored for importance using the Failure Mode and Effects Analysis methodology. Potential error occurrence (frequency) was derived according to the collected event data, along with the potential event severity, and the probability of detection with and without the theoretical implementation of the QAPV plan comparison check. Failure Mode and Effects Analysis Risk Priority Numbers (RPNs) with and without QAPV were compared to quantify the potential benefit of clinical implementation of QAPV. The implementation of QAPV could reduce the RPN values for 15 of 22 (71%) of evaluated parameters, with an overall average reduction in RPN of 68 (range, 0-216). For the 6 high-risk parameters (>200), the average reduction in RPN value was 163 (range, 108-216). The RPN value reduction for the intermediate-risk (200 > RPN > 100) parameters was (0-140). With QAPV, the largest RPN value for "Beam Meterset" was reduced from 324 to 108. The maximum reduction in RPN value was for Beam Meterset (216, 66.7%), whereas the maximum percentage reduction was for Cumulative Meterset Weight (80, 88.9%). This analysis quantifies the value of the Integrating the Healthcare Enterprise-Radiation Oncology QAPV implementation in clinical workflow. We demonstrate that although QAPV does not provide a

  19. CHANTI: a fast and efficient charged particle veto detector for the NA62 experiment at cern

    CERN Document Server

    Mirra, Marco

    This work has been performed into the frame of the NA62 experiment at CERN that aims at measuring the Branching-Ratio of the ultra-rare kaon decay K+→π+ nu nubar with 10% uncertainty - using an unseparated kaon beam of 75GeV/c - in order to test the Standard Model (SM), to look for physics beyond SM and to measure the |Vtd| element of the Cabibbo-Kobayashi-Maskawa (CKM) flavor mixing matrix. Backgrounds, which are up to 10^10 times higher than the signal, will be suppressed by an accurate measurement of the momentum of the K+ (with a silicon beam tracker named GigaTracker) and the π+ (with a straw tracker) and by a complex system of particle identification and veto detectors. A critical background can be induced by inelastic interactions of the hadron beam with the GigaTracker. Pions produced in these interactions, emitted at low angle, can reach the straw tracker and mimic a kaon decay in the fiducial region, if no other track is detected. In order to suppress this background a CHarged track ANTIcounter ...

    1987-01-01

    The Embedded System Safety Analysis Assistant (ESSAA) is a knowledge-based tool that can assist in identifying disaster scenarios. Imbedded software issues hazardous control commands to the surrounding hardware. ESSAA is intended to work from outputs to inputs, as a complement to simulation and verification methods. Rather than treating the software in isolation, it examines the context in which the software is to be deployed. Given a specified disasterous outcome, ESSAA works from a qualitative, abstract model of the complete system to infer sets of environmental conditions and/or failures that could cause a disasterous outcome. The scenarios can then be examined in depth for plausibility using existing techniques.

    Full Text Available The research object is inlet apparatus of ventricular assist device, namely inlet cannula and straightener.The purpose of the study is to reveal features of blood flow in inlet apparatus of ventricular assist device. The mathematical modeling is carried out by computational fluid dynamics analysis in a stationary setting.The first part of study concerns the analysis of existing approaches to the numerical and experimental studies in designing the ventricular assist devices of rotary type. It reveals the features of each approach for their further application in practice. The article presents an original design of developed hydraulic test bench to verify the results of mathematical modeling. Analysis of foreign authors’ studies showed that there is no enough attention paid to design of the adjacent pump assemblies of ventricular assist device. The second part of study considers direct mathematical modeling of input apparatus of ventricular assist device. The study examined straightener with three or four blades. Mathematical modeling has revealed the presence of potentially dangerous stagnation zones and essential asymmetry of the outlet flow from the input unit. The found features must be taken in consideration in designing the ventricular assist device pumps. In the future we plan to use obtained data to create a parametric model of the rotor and the diffuser considering the abovementioned features.

    2016-07-01

    XENON1T is the 3rd stage of a series of experiments performed by the XENON collaboration for the direct detection of dark matter candidates, such as WIMPs. Its projected spin-independent WIMP-nucleon elastic scattering cross-section entails an improvement of two orders of magnitude with respect to Xenon100 and requires, for a fiducial mass of the detector of about 1 ton liquid xenon, a similar reduction in background. In order to minimize the neutron background induced by cosmic ray muons, the XENON1T TPC is placed in the center of a 750 m{sup 3} water tank acting as an active Cherenkov muon veto, the walls of which are clad with the high reflective DF2000MA foil by 3M. The improved setup and results of a dedicated study of the reflective properties of the foil is presented, as well as a measurement of its possible wavelength shifting (WLS) properties. The analysis yields a specular reflectance of ∼ 100% for wavelengths larger than 400 nm, while ∼ 90% of the incoming light with wavelengths smaller than 370 nm is absorbed by the foil. The emission spectra of the WLS are dependent on the absorbed wavelength and show Gaussian shapes, with highest intensities at mean values of ∼ 450 nm emission wavelength.

    In this contribution, a concept of an assistive technology for hearing-impaired and deaf persons is presented. The concept applies pattern recognition algorithms and makes use of modern communication technology to analyze the acoustic environment around a user, identify critical acoustic signatures and give an alert to the user when an event of interest happened. A detailed analysis of the needs of deaf and hearing-impaired people has been performed. Requirements for an adequate assisting device have been derived from the results of the analysis, and have been turned into an architecture for its implementation that will be presented in this article. The presented concept is the basis for an assistive system which is now under development at the Institute of Microsystem Engineering at the University of Siegen.

    To investigate the effects of robot-assisted training on the recovery of people with spinal cord injury (SCI). Randomized controlled trials (RCTs) or quasi-RCTs involving people with SCI that compared robot-assisted upper limbs or lower limbs training with a control of other treatment approach or no treatment. We included studies involving people with complete or incomplete SCIs. We searched MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials (Cochrane Library), and Embase to August 2016. Bibliographies of relevant articles on the effect of body-weight-supported treadmill training on subjects with SCI were screened to avoid missing relevant articles from the search of databases. All kinds of objective assessments concerning physical ability, mobility, and/or functional ability were included. Assessments could be clinical tests (ie, 6-minute walk test, FIM) or laboratory tests (ie, gait analysis). Subjective outcome measures were excluded from this review. Eleven RCT studies involving 443 subjects were included in the study. Meta-analysis was performed on the included studies. Walking independence (3.73; 95% confidence interval [CI], -4.92 to -2.53; P<.00001; I 2 =38%) and endurance (53.32m; 95% CI, -73.15 to -33.48; P<.00001; I 2 =0%) were found to have better improvement in robot-assisted training groups. Lower limb robot-assisted training was also found to be as effective as other types of body-weight-supported training. There is a lack of upper limb robot-assisted training studies; therefore, performing a meta-analysis was not possible. Robot-assisted training is an adjunct therapy for physical and functional recovery for patients with SCI. Future high-quality studies are warranted to investigate the effects of robot-assisted training on functional and cardiopulmonary recovery of patients with SCI.

    Han, Jie; Zhang, Junfeng

    For the common problems existed in regional development and planning, we try to design a decision support system for assisting regional agricultural development and alignment as a decision-making tool for local government and decision maker. The analysis methods of forecast, comparative advantage, liner programming and statistical analysis are adopted. According to comparative advantage theory, the regional advantage can be determined by calculating and comparing yield advantage index (YAI), Scale advantage index (SAI), Complicated advantage index (CAI). Combining with GIS, agricultural data are presented as a form of graph such as area, bar and pie to uncover the principle and trend for decision-making which can't be found in data table. This system provides assistant decisions for agricultural structure adjustment, agro-forestry development and planning, and can be integrated to information technologies such as RS, AI and so on.

    Does medically assisted conception increase the risk of post-partum depressive symptoms? Our literature review and meta-analysis showed no increased risk of post-partum depressive symptoms in women after medically assisted conception. Women who conceive with medically assisted conception, which can be considered as a stressful life event, could face an increased risk of depressive symptoms. However, no previous meta-analysis has been performed on the association between medically assisted conception and post-partum depressive symptoms. A systematic review with electronic searches of PubMed, ISI Web of Knowledge and PsycINFO databases up to December 2014 was conducted to identify articles evaluating post-partum depressive symptoms in women who had benefited from medically assisted conception compared with those with a spontaneous pregnancy. Meta-analyses were also performed on clinically significant post-partum depressive symptoms according to PRISMA guidelines. From 569 references, 492 were excluded on title, 42 on abstract and 17 others on full-text. Therefore, 18 studies were included in the review and 8 in the meta-analysis (2451 women) on clinically significant post-partum depressive symptoms after medically assisted conception compared with a spontaneous pregnancy. A sensitivity meta-analysis on assisted reproductive technologies and spontaneous pregnancy (6 studies, 1773 women) was also performed. The quality of the studies included in the meta-analyses was evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology Statement for observational research. The data were pooled using RevMan software by the Cochrane Collaboration. Heterogeneity between studies was assessed from the results of the χ(2) and I(2) statistics. Biases were assessed with funnel plots and Egger's test. A fixed effects model was used for the meta-analyses because of the low level of heterogeneity between the studies.

    Full Text Available Background and objective The aim of this study is to assess the effect of video-assisted thoracoscopic surgery (VATS and video-assisted mini-thoracotomy (VAMT in the treatment of non-small cell lung cancer (NSCLC. Methods We searched PubMed, EMbase, CNKI, VIP and ISI Web of Science to collect randomized controlled trials (RCTs of VATS versus VAMT for NSCLC. Each database was searched from May 2006 to May 2016. Two reviewers independently assessed the quality of the included studies and extracted relevant data, using RevMan 5.3 meta-analysis software. Results We finally identified 13 RCTs involving 1,605 patients. There were 815 patients in the VATS group and 790 patients in the VAMT group. The results of meta-analysis were as follows: statistically significant difference was found in the harvested lymph nodes (SMD=-0.48, 95%CI: -0.80--0.17, operating time (SMD=13.56, 95%CI: 4.96-22.16, operation bleeding volume (SMD=-33.68, 95%CI: -45.70--21.66, chest tube placement time (SMD=-1.05, 95%CI: -1.48--0.62, chest tube drainage flow (SMD=-83.69, 95%CI: -143.33--24.05, postoperative pain scores (SMD=-1.68, 95%CI: -1.98--1.38 and postoperative hospital stay (SMD=-2.27, 95%CI: -3.23--1.31. No statistically significant difference was found in postoperative complications (SMD=0.83, 95%CI: 0.54-1.29 and postoperative mortality (SMD=0.95, 95%CI: 0.55-1.63 between videoassisted thoracoscopic surgery lobectomy and video-assisted mini-thoracotomy lobectomy in the treatment of NSCLC. Conclusion Compared with video-assisted mini-thoracotomy lobectomy in the treatment of non-small cell lung cancer, the amount of postoperative complications and postoperative mortality were almost the same in video-assisted thoracoscopic lobectomy, but the amount of harvested lymph nodes, operating time, blood loss, chest tube drainage flow, and postoperative hospital stay were different. VATS is safe and effective in the treatment of NSCLC.

    Virgo started collecting science data during weekends in order to not interfere with commissioning activities. The goal of Weekly Science Runs is to ease the transition between commissioning periods and data taking periods, in addition to providing data sets exploiting the stationary behavior of the detector. The detection of gravitational wave (GW) bursts emitted by core collapse of supernovae is one of the most difficult tasks for the GW community due to the fact that there are uncertainties in the exact shape of the waveforms, as we do not have complete models. A major task for this kind of detection effort is the cleaning of the event triggers found by the detection pipelines, namely the removal of accidental transient signals due to noise source events. In order to clean our data from false GW events, we need to define a strategy for data quality cut and veto of auxiliary and environmental monitoring channels. In this paper we report on the analysis we performed on data acquired during Weekly Science Runs to explore and define the data quality cut and veto studies for burst analysis

    There are many analysis techniques in order to analyze malicious codes. However, recently malicious codes often evade detection using stealthy obfuscation techniques, and attack computing systems. We propose an enhanced dynamic binary instrumentation using hardware-assisted virtualization technology. As a machine-level analyzer, our system can be isolated from almost the whole threats of malware, and provides single step analysis environment. Proposed system also supports rapid system call analysis environment. We implement our malware analysis system (referred as MAS) on the KVM hypervisor with Intel VT-x virtualization support. Our experiments with benchmarks show that the proposed system provides efficient analysis environment with low overhead.

    Reforms to Australia's disability and rehabilitation sectors have espoused the potential of assistive technology as an enabler. As new insurance systems are being developed it is timely to examine the structure of existing systems. This exploratory study examined the policies guiding assistive technology provision in the motor accident insurance sector of one Australian state. Policy documents were analyzed iteratively with set of qualitative questions to understand the intent and interpretation of policies guiding assistive technology provision. Content analysis identified relevant sections and meaningful terminology, and context analysis explored the dominant perspectives informing policy. The concepts and language of assistive technology are not part of the policy frameworks guiding rehabilitation practice in Queensland's motor accident insurance sector. The definition of rehabilitation in the legislation is consistent contemporary international interpretations that focus on optimizing functioning in interaction with the environment. However, the supporting documents are focused on recovery from injuries where decisions are guided by clinical need and affordability. The policies frame rehabilitation in a medical model that assistive technology provision from the rehabilitation plan. The legislative framework provides opportunities to develop and improve assistive technology provision as part of an integrated approach to rehabilitation.

    2017-09-01

    IceCube’s measurements of the astrophysical neutrino flux have applied veto techniques to suppress atmospheric neutrinos and muons. All the vetos thus far have used the outer regions of the detector to identify and reject penetrating muon tracks, leaving the inner parts of the detector available to observe the astrophysical neutrino flux. Here we discuss a method that is optimized for muon neutrinos which have a charged-current interaction with a contained vertex. This analysis exploits the high quality directional information of muons to determine a veto on an event by event basis. The final sample will contain astrophysical neutrinos with good purity starting around 10 TeV.

    Laparoscopic surgery is associated with a high degree of ergonomic stress. However, the stress associated with surgical assisting is not known. In this study, we compare the ergonomic stress associated with primary and assistant surgical roles during laparoscopic surgery. We hypothesize that higher ergonomic stress will be detected in the primary operating surgeon when compared with the surgical assistant. One right-hand dominant attending surgeon performed 698 min of laparoscopic surgery over 13 procedures (222 min primary and 476 min assisting), whereas electromyography data were collected from bilateral biceps, triceps, deltoids, and trapezius muscles. Data were analyzed in 1-min segments. Average muscle activation as quantified by maximal voluntary contraction (%MVC) was calculated for each muscle group during primary surgery and assisting. We compared mean %MVC values with unpaired t-tests. Activation of right (R) biceps and triceps muscle groups is significantly elevated while operating when compared with assisting (R biceps primary: 5.47 ± 0.21 %MVC, assistant: 3.93 ± 0.11, P ergonomic differences between operating and assisting. Surgical assisting was associated with similar and occasionally higher levels of muscle activation compared with primary operating. These findings suggest that surgical assistants face significant ergonomic stress, just as operating surgeons do. Steps must be taken to recognize and mitigate this stress in both operating surgeons and assistants. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-07-01

    Anesthesiologists play an important role in educating future clinicians. Yet few residency programs incorporate teaching skills into faculty development. Consequently, many anesthesiologists have limited training to supervise and educate residents. In turn, these attendings may receive negative feedback and poor evaluations from residents without a means to effectively improve. Peer-assisted teaching between faculty members may serve as a strategy to improve teaching skills. We report a case of peer-assisted analysis of resident feedback to identify specific areas of concern that were targeted for improvement. This approach resulted in improved teaching scores and feedback for the faculty member.

    2014-04-22

    In May 2013 a new Assisted Dying Bill was tabled in the House of Lords and is currently scheduled for a second reading in May 2014. The Bill was informed by the report of the Commission on Assisted Dying which itself was informed by evidence presented by invited experts.This study aims to explore how the experts presenting evidence to the Commission on Assisted Dying conceptualised mental capacity for patients requesting assisted suicide and examine these concepts particularly in relation to the principles of the Mental Capacity Act 2005. This study was a secondary qualitative analysis of 36 transcripts of oral evidence and 12 pieces of written evidence submitted by invited experts to the Commission on Assisted Dying using a framework approach. There was agreement on the importance of mental capacity as a central safeguard in proposed assisted dying legislation. Concepts of mental capacity, however, were inconsistent. There was a tendency towards a conceptual and clinical shift toward a presumption of incapacity. This appeared to be based on the belief that assisted suicide should only be open to those with a high degree of mental capacity to make the decision.The 'boundaries' around the definition of mental capacity appeared to be on a continuum between a circumscribed legal 'cognitive' definition of capacity (in which most applicants would be found to have capacity unless significantly cognitively impaired) and a more inclusive definition which would take into account wider concepts such as autonomy, rationality, voluntariness and decision specific factors such as motivation for decision making. Ideas presented to the Commission on Assisted Dying about mental capacity as it relates to assisted suicide were inconsistent and in a number of cases at variance with the principles of the Mental Capacity Act 2005. Further work needs to be done to establish a consensus as to what constitutes capacity for this decision and whether current legal frameworks are able to

    Building on the successful experience in operating the DarkSide-50 detector, the DarkSide Collaboration is going to construct DarkSide-20k, a direct WIMP search detector using a two-phase Liquid Argon Time Projection Chamber (LArTPC) with an active (fiducial) mass of 23 t (20 t). The DarkSide-20k LArTPC will be deployed within a shield/veto with a spherical Liquid Scintillator Veto (LSV) inside a cylindrical Water Cherenkov Veto (WCV). Operation of DarkSide-50 demonstrated a major reduction in the dominant $^{39}$Ar background when using argon extracted from an underground source, before applying pulse shape analysis. Data from DarkSide-50, in combination with MC simulation and analytical modeling, shows that a rejection factor for discrimination between electron and nuclear recoils of $\\gt3\\times10^9$ is achievable. This, along with the use of the veto system, is the key to unlocking the path to large LArTPC detector masses, while maintaining an "instrumental background-free" experiment, an experiment in which less than 0.1 events (other than $\

    Full Text Available To model and analyse stroke care and assistance provision in the Portuguese context from the network perspective. We used the network theory as a theoretical foundation for the study. The model proposed by Frey et al. (2006 was used to elicit and comprehend possible interactions and relations between organisations expected to be involved in the provision of care and assistance to stroke patients in their pathway to rehabilitation. Providers were identified and contacted to evaluate the nature and intensity of relationships. Network analysis was performed with the NodeXL software package. Analysis of 509 entities based on about 260 000 entries indicates that stroke care provision in the evaluated context is best captured in the coalition-collaboration setting, which appears to best demonstrate the character of the network. Information from analysis of the collaboration stage was not sufficient to determine the network dynamics. Application of the network theory to understand interorganisational dynamics of the complex health care context. Empirical validation of the model proposed by Frey et al. (2006 in terms of its operationalisation and the way it actually reflects the practical context.

    The legalization of medical assistance in dying will affect health care spending in Canada. Our aim was to determine the potential costs and savings associated with the implementation of medical assistance in dying. Using published data from the Netherlands and Belgium, where medically assisted death is legal, we estimated that medical assistance in dying will account for 1%-4% of all deaths; 80% of patients will have cancer; 50% of patients will be aged 60-80 years; 55% will be men; 60% of patients will have their lives shortened by 1 month; and 40% of patients will have their lives shortened by 1 week. We combined current mortality data for the Canadian population with recent end-of-life cost data to calculate a predicted range of savings associated with the implementation of medical assistance in dying. We also estimated the direct costs associated with offering medically assisted death, including physician consultations and drug costs. Medical assistance in dying could reduce annual health care spending across Canada by between $34.7 million and $138.8 million, exceeding the $1.5-$14.8 million in direct costs associated with its implementation. In sensitivity analyses, we noted that even if the potential savings are overestimated and costs underestimated, the implementation of mdedical assistance in dying will likely remain at least cost neutral. Providing medical assistance in dying in Canada should not result in any excess financial burden to the health care system, and could result in substantial savings. Additional data on patients who choose medical assistance in dying in Canada should be collected to enable more precise estimates of the impact of medically assisted death on health care spending and to enable further economic evaluation. © 2017 Canadian Medical Association or its licensors.

    Full Text Available The present paper presents an assessment of the effectiveness of Official Development Assistance (ODA in promoting growth and reducing poverty in recipient countries, as well as its capacity to influence the main macroeconomic variables such as investment, savings, consumption, tax burden and the rate of inflation. For this purpose, we use both classical regression analysis and a structural model. In the former case, ordinary least squares (OLS are used to estimate a series of equations in which ODA plays the role of independent variable. The second case involves a multiple-indicator, multiple-causes (MIMIC model with three latent variables, one of which, ODA, is exogenous.

    To evaluate how the introduction of robotic-assisted surgery affects treatment-related morbidity and cost of endometrial cancer (EC) staging. We retrospectively reviewed the records of consecutive patients with stage I-III EC undergoing surgical staging between 2007 and 2012 at our institution. Costs (from surgery to 30days after surgery) were set based on the Medicare cost-to-charge ratio for each year and inflated to 2014 values. Inverse probability weighting (IPW) was used to decrease the allocation bias when comparing outcomes between surgical groups. We focused our analysis on the 251 EC patients who had robotic-assisted surgery and the 384 who had open staging. During the study period, the use of robotic-assisted surgery increased and open staging decreased (P<0.001). Correcting group imbalances by using IPW methodology, we observed that patients undergoing robotic-assisted staging had a significantly lower postoperative complication rate, lower blood transfusion rate, longer median operating time, shorter median length of stay, and lower readmission rate than patients undergoing open staging (all P<0.001). Overall 30-day costs were similar between the 2 groups, with robotic-assisted surgery having significantly higher median operating room costs ($2820 difference; P<0.001) but lower median room and board costs ($2929 difference; P<0.001) than open surgery. Increasing experience with robotic-assisted staging was significantly associated with a decrease in median operating time (P=0.002) and length of stay (P=0.003). The implementation of robotic-assisted surgery for EC staging improves patient outcomes. It provides women the benefits of minimally invasive surgery without increasing costs and potentially improves patient turnover. Copyright © 2016 Elsevier Inc. All rights reserved.

    2015-01-01

    Renewable energy system is an important concern for sustainable development of the World. Thermodynamic analysis, especially exergy analysis is an intense tool to assess sustainability of the systems. Food processing industry is one of the energy intensive sectors where dairy industry consumes substantial amount of energy among other food industry segments. Therefore, in this study, thermodynamic analysis of a milk pasteurization process assisted by geothermal energy was studied. In the system, a water–ammonia VAC (vapor absorption cycle), a cooling section, a pasteurizer and a regenerator were used for milk pasteurization. Exergetic efficiencies of each component and the whole system were separately calculated. A parametric study was undertaken. In this regard, firstly the effect of the geothermal resource temperature on (i) the total exergy destruction of the absorption cycle and the whole system, (ii) the efficiency of the VAC, the whole system and COP (coefficient of performance) of the VAC, (iii) the flow rate of the pasteurized milk were investigated. Then, the effect of the geothermal resource flow rate on the pasteurization load was analyzed. The exergetic efficiency of the whole system was calculated as 56.81% with total exergy destruction rate of 13.66 kW. The exergetic results were also illustrated through the Grassmann diagram. - Highlights: • Geothermal energy assisted milk pasteurization system was studied thermodynamically. • The first study on exergetic analysis of a milk pasteurization process with VAC. • The thermodynamic properties of water–ammonia mixture were calculated by using EES. • Energetic and exergetic efficiency calculated as 71.05 and 56.81%, respectively.

  19. Continuous sedation until death as physician-assisted suicide/euthanasia: a conceptual analysis.

    Science.gov (United States)

    Lipuma, Samuel H

    2013-04-01

    A distinction is commonly drawn between continuous sedation until death and physician-assisted suicide/euthanasia. Only the latter is found to involve killing, whereas the former eludes such characterization. I argue that continuous sedation until death is equivalent to physician-assisted suicide/euthanasia in that both involve killing. This is established by first defining and clarifying palliative sedation therapies in general and continuous sedation until death in particular. A case study analysis and a look at current practices are provided. This is followed by a defense of arguments in favor of definitions of death centering on higher brain (neocortical) functioning rather than on whole brain or cardiopulmonary functioning. It is then shown that continuous sedation until death simulates higher brain definitions of death by eliminating consciousness. Appeals to reversibility and double effect fail to establish any distinguishing characteristics between the simulation of death that occurs in continuous sedation until death and the death that occurs as a result of physician-assisted suicide/euthanasia. Concluding remarks clarify the moral ramifications of these findings.

    PurposeProstatic artery embolization (PAE) is a safe and efficacious procedure for benign prostatic hyperplasia (BPH), though is technically challenging. We present our experience of technical and clinical outcomes of robotic and manual PAE in patients with BPH.Materials and MethodsIRB-approved retrospective study of 40 consecutive patients 49–81 years old with moderate or severe grade BPH from May 2014 to July 2015: 20 robotic-assisted PAE (group 1), 20 manual PAE (group 2). Robotic-assisted PAE was performed using the Magellan Robotic System. American Urological Association (AUA-SI) score, cost, technical and clinical success, radiation dose, fluoroscopy, and procedure time were reviewed. Statistical analysis was performed within and between each group using paired t test and one-way analysis of variance respectively, at 1 and 3 months.ResultsNo significant baseline differences in age and AUA-SI between groups. Technical success was 100% (group 1) and 95% (group 2). One unsuccessful subject from group 2 returned for a successful embolization using robotic assistance. Fluoroscopy and procedural times were similar between groups, with a non-significant lower patient radiation dose in group 1 (30,632.8 mGy/cm{sup 2} vs 35,890.9, p = 0.269). Disposable cost was significantly different between groups with the robotic-assisted PAE incurring a higher cost (group 1 $4530.2; group 2 $1588.5, p < 0.0001). Clinical improvement was significant in both arms at 3 months: group 1 mean change in AUA-SI of 8.3 (p = 0.006), group 2: 9.6 (p < 0.0001). No minor or major complications occurred.ConclusionsRobotic-assisted PAE offers technical success comparable to manual PAE, with similar clinical improvement with an increased cost.

    The aim of the study was to check the quality of computer-assisted sperm analysis (CASA) system in comparison to the reference manual method as well as standardization of the computer-assisted semen assessment. The study was conducted between January and June 2015 at the Andrology Laboratory of the Division of Infertility and Reproductive Endocrinology, Poznań University of Medical Sciences, Poland. The study group consisted of 230 men who gave sperm samples for the first time in our center as part of an infertility investigation. The samples underwent manual and computer-assisted assessment of concentration, motility and morphology. A total of 184 samples were examined twice: manually, according to the 2010 WHO recommendations, and with CASA, using the program set-tings provided by the manufacturer. Additionally, 46 samples underwent two manual analyses and two computer-assisted analyses. The p-value of p CASA and manually. In the group of patients where all analyses with each method were performed twice on the same sample we found no significant differences between both assessments of the same probe, neither in the samples analyzed manually nor with CASA, although standard deviation was higher in the CASA group. Our results suggest that computer-assisted sperm analysis requires further improvement for a wider application in clinical practice.

    Full Text Available The present work proposes a method for human gait and kinematic analysis. Gait analysis consists of the determination of hip, knee and ankle positions through video analysis. Gait kinematic for the thigh and knee is then generated from this data. Evaluations of the gait analysis method indicate an acceptable performance of 86.66% for hip and knee position estimation, and comparable findings with other reported works for gait kinematic. A coordinate systems assignment is performed according to the DH algorithm and a direct kinematic model of the legs is obtained. The legs' angles obtained from the video analysis are applied to the kinematic model in order to revise the application of this model to robotic legs in a power assisted system.

    2017-09-01

    In this paper, the ultrasound-assisted leaching of iron from boron carbide waste-scrap was investigated and the optimization of different influencing factors had also been performed. The factors investigated were acid concentration, liquid-solid ratio, leaching temperature, ultrasonic power and frequency. The leaching of iron with conventional method at various temperatures was also performed. The results show the maximum iron leaching ratios are 87.4%, 94.5% for 80min-leaching with conventional method and 50min-leaching with ultrasound assistance, respectively. The leaching of waste-scrap with conventional method fits the chemical reaction-controlled model. The leaching with ultrasound assistance fits chemical reaction-controlled model, diffusion-controlled model for the first stage and second stage, respectively. The assistance of ultrasound can greatly improve the iron leaching ratio, accelerate the leaching rate, shorten leaching time and lower the residual iron, comparing with conventional method. The advantages of ultrasound-assisted leaching were also confirmed by the SEM-EDS analysis and elemental analysis of the raw material and leached solid samples. Copyright © 2017 Elsevier B.V.

    Fast and accurate graft hepatic steatosis (HS) assessment is of primary importance for lowering liver dysfunction risks after transplantation. Histopathological analysis of biopsied liver is the gold standard for assessing HS, despite being invasive and time consuming. Due to the short time availability between liver procurement and transplantation, surgeons perform HS assessment through clinical evaluation (medical history, blood tests) and liver texture visual analysis. Despite visual analysis being recognized as challenging in the clinical literature, few efforts have been invested to develop computer-assisted solutions for HS assessment. The objective of this paper is to investigate the automatic analysis of liver texture with machine learning algorithms to automate the HS assessment process and offer support for the surgeon decision process. Forty RGB images of forty different donors were analyzed. The images were captured with an RGB smartphone camera in the operating room (OR). Twenty images refer to livers that were accepted and 20 to discarded livers. Fifteen randomly selected liver patches were extracted from each image. Patch size was [Formula: see text]. This way, a balanced dataset of 600 patches was obtained. Intensity-based features (INT), histogram of local binary pattern ([Formula: see text]), and gray-level co-occurrence matrix ([Formula: see text]) were investigated. Blood-sample features (Blo) were included in the analysis, too. Supervised and semisupervised learning approaches were investigated for feature classification. The leave-one-patient-out cross-validation was performed to estimate the classification performance. With the best-performing feature set ([Formula: see text]) and semisupervised learning, the achieved classification sensitivity, specificity, and accuracy were 95, 81, and 88%, respectively. This research represents the first attempt to use machine learning and automatic texture analysis of RGB images from ubiquitous smartphone

    The LIGO Scientific Collaboration (LSC) glitch group is part of the LIGO detector characterization effort. It consists of data analysts and detector experts who, during and after science runs, collaborate for a better understanding of noise transients in the detectors. Goals of the glitch group during the fifth LIGO science run (S5) included (1) offline assessment of the detector data quality, with focus on noise transients, (2) veto recommendations for astrophysical analysis and (3) feedback to the commissioning team on anomalies seen in gravitational wave and auxiliary data channels. Other activities included the study of auto-correlation of triggers from burst searches, stationarity of the detector noise and veto studies. The group identified causes for several noise transients that triggered false alarms in the gravitational wave searches; the times of such transients were identified and vetoed from the data generating the LSC astrophysical results.

    2015-01-01

    Therapist-assisted Internet-delivered cognitive behavior therapy (ICBT) involves elements of expressive writing through secure messaging with a therapist. Expressive writing has been associated with psychological and physical health benefits in past research; furthermore, certain linguistic dimensions in expressive writing have been identified as particularly beneficial to health, such as less frequent use of negative emotion words and greater use of positive emotion words. No research, to date, has analyzed linguistic dimensions in client communication over the course of therapist-assisted ICBT for individuals with symptoms of generalized anxiety. This naturalistic study examined messages sent to therapists during the course of ICBT using linguistic analysis, and explored covariation of word use with symptom improvement. Data were obtained from patients with symptoms of generalized anxiety (N = 59) who completed 12 modules of therapist-assisted ICBT and rated symptoms of anxiety, depression, and panic at the beginning of each module. Linguistic analysis categorized text submitted to therapists into different word categories. Results found that patients' use of negative emotion, anxiety, causation, and insight words reduced over the course of treatment, while past tense words increased. Furthermore, negative emotion words significantly covaried with symptom ratings over the course of treatment. While causal statements cannot be made, findings improve our understanding of patient communication in ICBT and suggest that the further study of linguistic dimensions as psychological indicators and the potential utility of expressive writing strategies in therapist-assisted ICBT may be worthwhile.

  1. A novel software assistant for the clinical analysis of MR spectroscopy with MeVisLab

    2008-03-01

    We present a novel software assistant for the analysis of multi-voxel 2D or 3D in-vivo-spectroscopy signals based on the rapid-prototyping platform MeVisLab. Magnetic Resonance Spectroscopy (MRS) is a valuable in-vivo metabolic window into tissue regions of interest, such as the brain, breast or prostate. With this method, the metabolic state can be investigated non-invasively. Different pathologies evoke characteristically different MRS signals, e.g., in prostate cancer, choline levels increase while citrate levels decrease compared to benign tissue. Concerning the majority of processing steps, available MRS tools lack performance in terms of speed. Our goal is to support clinicians in a fast and robust interpretation of MRS signals and to enable them to interactively work with large volumetric data sets. These data sets consist of 3D spatially resolved measurements of metabolite signals. The software assistant provides standard analysis methods for MRS data including data import and filtering, spatio-temporal Fourier transformation, and basic calculation of peak areas and spectroscopic metabolic maps. Visualization relies on the facilities of MeVisLab, a platform for developing clinically applicable software assistants. It is augmented by special-purpose viewing extensions and offers synchronized 1D, 2D, and 3D views of spectra and metabolic maps. A novelty in MRS processing tools is the side-by-side viewing ability of standard FT processed spectra with the results of time-domain frequency analysis algorithms like Linear Prediction and the Matrix Pencil Method. This enables research into the optimal toolset and workflow required to avoid misinterpretation and misapplication.

    Fifty-one sequential gallium citrate scans were performed in 22 patients with biopsy-proven sarcoidosis. A computer-assisted quantitative analysis of these scans was performed to obtain a gallium score. The changes in gallium score were correlated with changes in serum angiotensin converting enzyme (SACE) activity and objective changes in clinical status. There was a good concordance between changes in gallium score, SACE activity and clinical assessment in patients with sarcoidosis, and changes in gallium index were slightly superior to SACE index in assessing activity of sarcoidosis.

    Laser assisted vascular anastomosis (LAVA) is looked as a particularly promising non-suture method in future. However, aneurysm formation is one of the main reasons delay the clinical application of LAVA. Some scientists investigated the incidence of aneurysms in animal model. To systematically analyze the literature on reported incidence of aneurysm formation in LAVA therapy, we performed a meta-analysis comparing LAVA with conventional suture anastomosis (CSA) in animal model. Data were systematically retrieved and selected from PUBMED. In total, 23 studies were retrieved. 18 studies were excluded, and 5 studies involving 647 animals were included. Analysis suggested no statistically significant difference between LAVA and CSA (OR 1.24, 95%CI 0.66-2.32, P=0.51). Result of meta analysis shows that the technology of LAVA is very close to clinical application.

    Chronic obstructive pulmonary disease (COPD) is often accompanied by acute exacerbations. Patients of COPD exacerbation suffering from respiratory failure often need the support of mechanical ventilation. Helium-oxygen can be used to reduce airway resistance during mechanical ventilation. The aim of this study is to evaluate the effect of helium-oxygen-assisted mechanical ventilation on COPD exacerbation through a meta-analysis. A comprehensive literature search through databases of Pub Med (1966∼2016), Ovid MEDLINE (1965∼2016), Cochrane EBM (1991∼2016), EMBASE (1974∼2016) and Ovid MEDLINE was performed to identify associated studies. Randomized clinical trials met our inclusion criteria that focus on helium-oxygen-assisted mechanical ventilation on COPD exacerbation were included. The quality of the papers was evaluated after inclusion and information was extracted for meta-analysis. Six articles and 392 patients were included in total. Meta-analysis revealed that helium-oxygen-assisted mechanical ventilation reduced Borg dyspnea scale and increased arterial PH compared with air-oxygen. No statistically significant difference was observed between helium-oxygen and air-oxygen as regards to WOB, PaCO 2 , OI, tracheal intubation rates and mortality within hospital. Our study suggests helium-oxygen-assisted mechanical ventilation can help to reduce Borg dyspnea scale. In terms of the tiny change of PH, its clinical benefit is negligible. There is no conclusive evidence indicating the beneficial effect of helium-oxygen-assisted mechanical ventilation on clinical outcomes or prognosis of COPD exacerbation. © 2017 John Wiley & Sons Ltd.

    2007-12-01

    Full Text Available While approaches that had already established historical precedents – computer-assisted analytical approaches drawing on statistics and information theory – developed further, many research projects conducted during the 1980s aimed at the development of new methods of computer-assisted music analysis. Some projects discovered new possibilities related to using computers to simulate human cognition and perception, drawing on cognitive musicology and Artificial Intelligence, areas that were themselves spurred on by new technical developments and by developments in computer program design. The 1990s ushered in revolutionary methods of music analysis, especially those drawing on Artificial Intelligence research. Some of these approaches started to focus on musical sound, rather than scores. They allowed music analysis to focus on how music is actually perceived. In some approaches, the analysis of music and of music cognition merged. This article provides an overview of computer-assisted music analysis of the 1980s and 1990s, as it relates to music cognition. Selected approaches are being discussed.

The kinetic energy of cosmogenic muons depends on the progenitor particle, hence they can have an energy which is high enough to penetrate even the deepest underground laboratory. For this reason GERDA is equipped with a powerful muon veto system which in most parts was developed in Tuebingen. In this work, a plastic scintillator veto was added to the existing water Cherenkov veto in order to protect a weak spot. Existing hardware was maintained, frequently calibrated and faulty modules exchanged when possible. The DAQ and analysis was upgraded in order to run both veto systems simultaneously. The system was simulated with a GEANT4-based Monte-Carlo simulation. Multiplicity and photon spectra of the simulations were found to be in good agreement with the experimental data and give an efficiency for the detection of energy-depositing muons of ε{sup sim}{sub μd}=(99.935±0.015)%. Two external effects were clearly identified in the muon veto data: additional muons originating from the CNGS-beam at CERN and an annual flux modulation due to seasonal atmospheric temperature changes. Both effects were measured with high precision and agree well with other experiments. Coincidences with the germanium detectors were studied and muon-germanium coincidences were clearly identified. By defining a muon cut, a muon rejection efficiency of the germanium detectors of ε{sup Ge}{sub μr}=(99.2{sup +0.3}{sub -0.4})% was found. Two methods were pursued to find radioactive isotopes produced by muons through spallation or neutron activation. The result of both methods is compatible with zero, i.e. no events could be clearly identified. The overall functionality of the muon veto for Phase I of GERDA was successfully maintained and verified.

    Bibi, Aisha; Ju, Huangxian

    2016-04-01

    A quantum dots (QDs) assisted laser desorption/ionization mass spectrometric (QDA-LDI-MS) strategy was proposed for qualitative and quantitative analysis of a series of carbohydrates. The adsorption of carbohydrates on the modified surface of different QDs as the matrices depended mainly on the formation of hydrogen bonding, which led to higher MS intensity than those with conventional organic matrix. The effects of QDs concentration and sample preparation method were explored for improving the selective ionization process and the detection sensitivity. The proposed approach offered a new dimension to the application of QDs as matrices for MALDI-MS research of carbohydrates. It could be used for quantitative measurement of glucose concentration in human serum with good performance. The QDs served as a matrix showed the advantages of low background, higher sensitivity, convenient sample preparation and excellent stability under vacuum. The QDs assisted LDI-MS approach has promising application to the analysis of carbohydrates in complex biological samples. Copyright © 2016 John Wiley & Sons, Ltd.

  12. Opening up to Big Data: Computer-Assisted Analysis of Textual Data in Social Sciences

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available Two developments in computational text analysis may change the way qualitative data analysis in social sciences is performed: 1. the availability of digital text worth to investigate is growing rapidly, and 2. the improvement of algorithmic information extraction approaches, also called text mining, allows for further bridging the gap between qualitative and quantitative text analysis. The key factor hereby is the inclusion of context into computational linguistic models which extends conventional computational content analysis towards the extraction of meaning. To clarify methodological differences of various computer-assisted text analysis approaches the article suggests a typology from the perspective of a qualitative researcher. This typology shows compatibilities between manual qualitative data analysis methods and computational, rather quantitative approaches for large scale mixed method text analysis designs.

  13. Three Paradigms of Social Assistance

    Directory of Open Access Journals (Sweden)

    Pierre-Marc Daigneault

    2014-11-01

    Full Text Available “Ideas,” which are defined as the normative and cognitive beliefs of actors, are fundamental to a full understanding of the welfare state and, in particular, of social assistance. However, policy ideas have been neglected in most typologies of social assistance regimes. Based on a selective review of the literature, this article proposes a brief but systematic analysis of policy paradigms in the field of social assistance. Three ideal types that emphasize the ideational dimension of social assistance are analyzed, namely, the entitlement, workfare, and activation paradigms. The value of the typology lies in its utility for characterizing the ideational orientation of social assistance regimes. Specifically, the typology provides a yardstick for measuring the ideas of policy actors with respect to social assistance and can facilitate the conduct of case studies, comparative research, and causal analyses on this policy sector.

    Assisted reproduction technology laboratories have a very high degree of complexity. Mismatches of gametes or embryos can occur, with catastrophic consequences for patients. To minimize the risk of error, a multi-institutional working group applied failure mode and effects analysis (FMEA) to each critical activity/step as a method of risk assessment. This analysis led to the identification of the potential failure modes, together with their causes and effects, using the risk priority number (RPN) scoring system. In total, 11 individual steps and 68 different potential failure modes were identified. The highest ranked failure modes, with an RPN score of 25, encompassed 17 failures and pertained to "patient mismatch" and "biological sample mismatch". The maximum reduction in risk, with RPN reduced from 25 to 5, was mostly related to the introduction of witnessing. The critical failure modes in sample processing were improved by 50% in the RPN by focusing on staff training. Three indicators of FMEA success, based on technical skill, competence and traceability, have been evaluated after FMEA implementation. Witnessing by a second human operator should be introduced in the laboratory to avoid sample mix-ups. These findings confirm that FMEA can effectively reduce errors in assisted reproduction technology laboratories. Copyright © 2016 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    2011-01-01

    Transformational leadership (TL) has long been popular among management scholars and health services researchers, but no research studies have empirically tested the association of TL with workplace injuries and absenteeism among nursing assistants (NAs). This cross-sectional study seeks to explore whether TL is associated with workplace injuries and absenteeism among NAs. We analyzed the 2004 National Nursing Assistant Survey data (n = 2,882). A multivariate logistic regression analysis was performed to test the role of TL in the context of workplace performances. Results reveal that the TL model was positively linked to workplace injury in the level of NAs. Injury-related absenteeism was also associated with the TL style, indicating that TL behaviors may help address workplace absence among NAs. Findings suggest that introducing TL practices may benefit NAs in improving workplace performances.

    2012-11-01

    There is legislation that withdraws governmental assistance where parents are using drugs. Social justice is an important consideration in any policy that modifies governmental assistance that benefits vulnerable children. The purpose of this policy analysis is to analyze identified legislation that effect governmental assistance for children in response to parents' substance misuse. A selective review of data-driven studies examined findings describing actual or potential effects on children of legislation targeting parental substance misuse. Challenges in design, processes, and implementation contribute to poor child outcomes. Identifiable constructs of social justice were missing in the reviewed legislation. Social injustice is a potential outcome for children when legislative intent focuses solely on addressing parental drug behaviors. Legislative alternatives to withdrawing support can address substance abuse while maintaining health promotion for these vulnerable children.

    2008-01-01

    A system analysis has been performed to assess the efficiency and carbon utilization of a nuclear-assisted coal gasification process. The nuclear reactor is a high-temperature helium-cooled reactor that is used primarily to provide power for hydrogen production via high-temperature electrolysis. The supplemental hydrogen is mixed with the outlet stream from an oxygen-blown coal gasifier to produce a hydrogen-rich gas mixture, allowing most of the carbon dioxide to be converted into carbon monoxide, with enough excess hydrogen to produce a syngas product stream with a hydrogen/carbon monoxide molar ratio of about 2:1. Oxygen for the gasifier is also provided by the high-temperature electrolysis process. Results of the analysis predict 90.5% carbon utilization with a syngas production efficiency (defined as the ratio of the heating value of the produced syngas to the sum of the heating value of the coal plus the high-temperature reactor heat input) of 66.1% at a gasifier temperature of 1866 K for the high-moisture-content lignite coal considered. Usage of lower moisture coals such as bituminous can yield carbon utilization approaching 100% and 70% syngas production efficiency

    2016-03-01

    The purpose of the present study was to compare the clinical and radiographic results and survival rates between computer-assisted and conventional closing wedge high tibial osteotomies (HTOs). Data from a consecutive cohort comprised of 75 computer-assisted HTOs and 75 conventional HTOs were retrospectively reviewed. The Knee Society knee and function scores, Hospital for Special Surgery (HSS) score and femorotibial angle (FTA) were compared between the two groups. Survival rates were also compared with procedure failure. The knee and function scores at one year postoperatively were slightly better in the computer-assisted group than those in conventional group (90.1 vs. 86.1) (82.0 vs. 76.0). The HSS scores at one year postoperatively were slightly better for the computer-assisted HTOs than those of conventional HTOs (89.5 vs. 81.8). The inlier of the postoperative FTA was wider in the computer-assisted group than that in the conventional HTO group (88.0% vs. 58.7%), and mean postoperative FTA was greater in the computer-assisted group that in the conventional HTO group (valgus 9.0° vs. valgus 7.6°, pclinical and radiographic results were better in the computer-assisted group that those in the conventional HTO group. Mid-term survival rates did not differ between computer-assisted and conventional HTOs. A comparative analysis of longer-term survival rate is required to demonstrate the long-term benefit of computer-assisted HTO. III. Copyright © 2015 Elsevier B.V. All rights reserved.

  2. Forward physics results from ATLAS

    Brown, Gareth John Ashley

    2012-01-01

    The measurements of rapidity gap cross sections and dijet production with a veto on additional central jet activity, performed at the ATLAS experiment at the LHC, are discussed. The rapidity gap cross section analysis measures the differential cross section as a function of the forward rapidity gap size. The data are compared to PYTHIA 8, PYTHIA 6 and PHOJET. The measured cross section is approximately 1mb per forward rapidity gap size for a gap size greater than 3. The measurement of dijet production with a veto on additional central jet activity studies the fraction of dijet events that remain after the application of a jet veto of 20 GeV in the rapidity interval bounded by the dijet system. This fraction is presented against the rapidity separation of the boundary dijets (in the range 0 - T < 500 GeV). The data are compared to a next-to-leading order plus parton shower prediction from the POWHEG-BOX and an all-order resummation using the HEJ calculation. (author)

    2016-01-01

    The objective of this study is to review the current state and role of computer-assisted analysis in diagnosis of plus disease in retinopathy of prematurity. Diagnosis and documentation of retinopathy of prematurity are increasingly being supplemented by digital imaging. The incorporation of computer-aided techniques has the potential to add valuable information and standardization regarding the presence of plus disease, an important criterion in deciding the necessity of treatment of vision-threatening retinopathy of prematurity. A review of literature found that several techniques have been published examining the process and role of computer aided analysis of plus disease in retinopathy of prematurity. These techniques use semiautomated image analysis techniques to evaluate retinal vascular dilation and tortuosity, using calculated parameters to evaluate presence or absence of plus disease. These values are then compared with expert consensus. The study concludes that computer-aided image analysis has the potential to use quantitative and objective criteria to act as a supplemental tool in evaluating for plus disease in the setting of retinopathy of prematurity.

  4. Analysis of Former Learning Assistants' Views on Cooperative Learning

    2009-11-01

    The University of Colorado Learning Assistant (LA) program integrates a weekly education seminar, meetings with science faculty to review content, and a semester-long teaching experience that hires undergraduates to work with groups of students in university science courses. Following this three-pronged learning experience, some of the LAs continue into the teacher certification program. While previous research has shown that this model has more than doubled the number of science and math majors graduating with a teaching certification, the question remains whether these teachers are better prepared to teach. The analysis presented here addresses this question by comparing the views of former LAs to the views of comparable teachers on the issue of cooperative learning. Interviews were conducted with ten middle school and high school science teachers throughout their first year of teaching. Results suggest differences in former LAs views toward group work and their purposes for using group work.

    Albrecht, R; Haase, D; Zippel, R; Koch, H; Settmacher, U

    2017-12-01

    By means of a matched-pair analysis comparing data obtained from laparoscopic cholecystectomy (LC) and robot-assisted laparoscopic cholecystectomy (RAC), the value of both methods as well as the advantages and disadvantages of both approaches were elucidated. The consideration was carried out by evaluation of postoperative surgical results, a cost analysis and a subjective survey of the patients using a questionnaire. Thus, from the 35 consecutive RAC, 35 (parallel) retrospectively matched pairs were established. Postoperative surgical results did not show any significant differences between LC and RAC. In the individual assessment by each patient, there were also no significant differences; however, there was a tendency towards the assessment of the RAC to be slightly worse. A striking difference was found with respect to the cost analysis at the time of surgery. The RAC operation alone is significantly more expensive compared to LC with respect to maintenance and acquisition costs. In addition, RAC can at present not be completely reimbursed under the current German diagnosis-related system. The postulated advantages of RAC comprise mainly the precise preparation within narrow confinements and the favorable ergonomic handling for the surgeon. The basic prerequisites are control of the costs and a reasonable reflection in the current reimbursement system.

    Both active euthanasia and assisted suicide are legal in The Netherlands, Belgium, Luxemburg and, most recently, in Canada. Examination of national legislations of countries where both active euthanasia and assisted suicide are legal. The number of accomplished active euthanasia cases and that of assisted suicide cases. Analysis of national statistical data. Comparison of statistical data before and after 2010. Comparison of the related practices in the surveyed countries. The number of active euthanasia cases markedly predominates over the number of assisted suicide cases. Cancer is a main reason for active euthanasia, or assisted suicide. In countries with a larger population, the number of active euthanasia cases is higher than that in countries with a smaller population. Regarding the fact that the applicants for active euthanasia withdraw their requests in a smaller number than the applicants for assisted suicide, patients prefer the choice of active euthanasia. Since the related legislative product is too recent in Canada at present, it may be only presumed that a certain preference will also develop in the related practices in Canada. Orv.

    Science.gov (United States)

    Patel, Kant

    2004-01-01

    This article presents a comparative analysis of euthanasia and physician-assisted suicide policy in The Netherlands and the state of Oregon in the United States. The topics of euthanasia and physician-assisted suicide are discussed in the context of the historical setting of The Netherlands and the United States with special emphasis placed on public opinion, role of the courts and the legislative bodies, and opinions of physicians. Major similarities and differences in the laws of The Netherlands and Oregon are discussed. The article examines whether the passage of the law has led to a slide down the slippery slope in The Netherlands and Oregon as had been suggested by the opponents of the law. The article concludes that the empirical evidence does not support the contention of the opponents. However, the author argues that the potential for this happening is much greater in The Netherlands than in Oregon.

    Grain size of the CIGS absorber is an important monitoring factor in the CIGS solar cell manufacturing. Electron backscatter diffraction (EBSD) analysis is commonly used to perform CIGS grain size analysis in the scanning electron microscope (SEM). Although direct quantification on SEM image using the average grain intercept (AGI) method is faster and simpler than EBSD, it is hardly applicable on CIGS thin films. The challenge is that, not like polycrystalline silicon, to define grain boundaries by selective chemical etching is not easily realizable for the multi-component CIGS alloy. In this Letter, we present direct quantification of CIGS thin film grain size using the AGI method by developing metal-assisted wet chemical etching process to define CIGS grain boundaries. The calculated value is similar to EBSD result. (copyright 2016 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    To perform a cost analysis comparing the cost of robot-assisted radical cystectomy (RARC) with open RC (ORC) in a UK tertiary referral centre and to identify the key cost drivers. Data on hospital length of stay (LOS), operative time (OT), transfusion rate, and volume and complication rate were obtained from a prospectively updated institutional database for patients undergoing RARC or ORC. A cost decision tree model was created. Sensitivity analysis was performed to find key drivers of overall cost and to find breakeven points with ORC. Monte Carlo analysis was performed to quantify the variability in the dataset. One RARC procedure costs £12 449.87, or £12 106.12 if the robot was donated via charitable funds. In comparison, one ORC procedure costs £10 474.54. RARC is 18.9% more expensive than ORC. The key cost drivers were OT, LOS, and the number of cases performed per annum. High ongoing equipment costs remain a large barrier to the cost of RARC falling. However, minimal improvements in patient quality of life would be required to offset this difference. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

  15. Energy-Based Analysis of Ultrasonically Assisted Turning

    Directory of Open Access Journals (Sweden)

    G.A. Volkov

    2011-01-01

    Full Text Available The process of ultrasonically-assisted turning (UAT is a superposition of vibration of a cutting tool on its standard movement in conventional turning (CT. The former technique has several advantages compared with the latter, one of the main being a significant decrease in the level of cutting forces. In this paper the effects observed in UAT are analysed employing ideas of dynamic fracture mechanics. The active stage of loading duration depends heavily on ultrasonic frequency and the cutting speed; he application of the fracture criterion based on the notion of incubation time makes it possible to calculate a dependence of this duration on its threshold amplitude. An estimation of energy, necessary to create a threshold pulse in the material, is made by solving the contact Hertz problem. The obtained time dependence of energy has a marked minimum. Thus, the existence of energy-efficient loading duration is demonstrated. This explains the decrease in the cutting force resulting from superimposed ultrasonic vibration. The obtained results are in agreement with experiments on ultrasonic assisted machining of aluminium and Inconel 718 alloy.

    Quantum confinement in nanoscale materials allows Auger-type electron-hole energy exchange. We show by direct time-domain atomistic simulation and analytic theory that Auger processes give rise to a new mechanism of charge transfer (CT) on the nanoscale. Auger-assisted CT eliminates the renown Marcus inverted regime, rationalizing recent experiments on CT from quantum dots to molecular adsorbates. The ab initio simulation reveals a complex interplay of the electron-hole and charge-phonon channels of energy exchange, demonstrating a variety of CT scenarios. The developed Marcus rate theory for Auger-assisted CT describes, without adjustable parameters, the experimental plateau of the CT rate in the region of large donor-acceptor energy gap. The analytic theory and atomistic insights apply broadly to charge and energy transfer in nanoscale systems.

    The aim of this study was to build an eligible population pharmacokinetic (PK) model for olanzapine in Chinese psychotic patients based on therapeutic drug monitoring (TDM) data, with assistance of meta-analysis, to facilitate individualized therapy. Population PK analysis for olanzapine was performed using NONMEM software (version 7.3.0). TDM data were collected from Guangzhou Brain Hospital (China). Because of the limitations of TDM data, model-based meta-analysis was performed to construct a structural model to assist the modeling of TDM data as prior estimates. After analyzing related covariates, a simulation was performed to predict concentrations for different types of patients under common dose regimens. A two-compartment model with first-order absorption and elimination was developed for olanzapine oral tablets, based on 23 articles with 390 data points. The model was then applied to the TDM data. Gender and smoking habits were found to be significant covariates that influence the clearance of olanzapine. To achieve a blood concentration of 20 ng/mL (the lower boundary of the recommended therapeutic range), simulation results indicated that the dose regimen of olanzapine should be 5 mg BID (twice a day), ≥ 5 mg QD (every day) plus 10 mg QN (every night), or >10 mg BID for female nonsmokers, male nonsmokers and male smokers, respectively. The population PK model, built using meta-analysis, could facilitate the modeling of TDM data collected from Chinese psychotic patients. The factors that significantly influence olanzapine disposition were determined and the final model could be used for individualized treatment.

    Intact spores and/or hyphae of Aspergillus niger, Rhizopus oryzae, Trichoderma reesei and Phanerochaete chrysosporium are analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). This study investigates various methods of sample preparation and matrices to determine optimum collection and analysis criteria for fungal analysis by MALDI-MS. Fungi are applied to the MALDI sample target as untreated, sonicated, acid/heat treated, or blotted directly from the fungal culture with double-stick tape. Ferulic acid or sinapinic acid matrix solution is layered over the dried samples and analyzed by MALDI-MS. Statistical analysis of the data show that simply using double stick tape to collect and transfer to a MALDI sample plate typically worked as well as the other preparation methods, but requires the least sample handling.

    2014-01-01

    Background Robotic-assisted laparoscopy is popularly performed for colorectal disease. The objective of this meta-analysis was to compare the safety and efficacy of robotic-assisted colorectal surgery (RCS) and laparoscopic colorectal surgery (LCS) for colorectal disease based on randomized controlled trial studies. Methods Literature searches of electronic databases (Pubmed, Web of Science, and Cochrane Library) were performed to identify randomized controlled trial studies that compared the clinical or oncologic outcomes of RCS and LCS. This meta-analysis was performed using the Review Manager (RevMan) software (version 5.2) that is provided by the Cochrane Collaboration. The data used were mean differences and odds ratios for continuous and dichotomous variables, respectively. Fixed-effects or random-effects models were adopted according to heterogeneity. Results Four randomized controlled trial studies were identified for this meta-analysis. In total, 110 patients underwent RCS, and 116 patients underwent LCS. The results revealed that estimated blood losses (EBLs), conversion rates and times to the recovery of bowel function were significantly reduced following RCS compared with LCS. There were no significant differences in complication rates, lengths of hospital stays, proximal margins, distal margins or harvested lymph nodes between the two techniques. Conclusions RCS is a promising technique and is a safe and effective alternative to LCS for colorectal surgery. The advantages of RCS include reduced EBLs, lower conversion rates and shorter times to the recovery of bowel function. Further studies are required to define the financial effects of RCS and the effects of RCS on long-term oncologic outcomes. PMID:24767102

    : Objective: To compare the safety/efficacy of the robotic-assisted lobectomy/segmentectomy (RAL/S) with the video-assisted lobectomy/segmentectomy (VAL/S) for radical lung cancer resection. It remains uncertain whether the newly developed RAL/S is comparable with the VAL/S. A comprehensive search of online databases was performed. Perioperative outcomes were synthesized. Cumulative meta-analysis was performed to evaluate the temporal trend of pooled outcomes. Specific subgroups (propensity score matching studies, pure lobectomy studies) were examined. Analysis of 14 studies including a total of 7438 patients was performed. RAL/S was performed on 3239 patients, whereas the other 4199 patients underwent VAL/S. The 30-day mortality [0.7% vs 1.1%; odds ratio (OR) 0.53, P = 0.045] and conversion rate to open surgery (10.3% vs 11.9%; OR 0.57, P < 0.001) were significantly lower in patients who underwent RAL/S than VAL/S. Meanwhile, the postoperative complications (27.5% vs 28.2%; OR 0.95, P = 0.431), operation time [176.63 vs 162.74 min; standardized mean difference (SMD) 0.30, P = 0.086], duration of hospitalization (4.90 vs 5.23 days; SMD -0.08, P = 0.292), days to tube removal (4.10 vs 3.53 days; SMD 0.25, P = 0.120), retrieved lymph node (11.96 vs 10.67; SMD 0.46, P = 0.381), and retrieved lymph node station (4.98 vs 4.32; SMD 0.83, P = 0.261) were similar between the 2 groups. The cumulative meta-analyses suggested that the relative effects between 2 groups have already stabilized. All outcomes of subgroup and overall analyses were similar. This up-to-date meta-analysis confirms that RAL/S is a feasible and safe alternative to VAL/S for radical resection of lung cancer. Future studies should focus on the long-term benefits and cost effectiveness of RAL/S compared with VAL/S.

    The role of a robotic assistant in laparoscopic cholecystectomy is controversial. While some trials have shown distinct advantages of a robotic assistant over a human assistant others have not, and it is unclear which robotic assistant is best. The aims of this review are to assess the benefits and harms of a robot assistant versus human assistant or versus another robot assistant in laparoscopic cholecystectomy, and to assess whether the robot can substitute the human assistant. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded (until February 2012) for identifying the randomised clinical trials. Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing robot assistants versus human assistants in laparoscopic cholecystectomy were considered for the review. Randomised clinical trials comparing different types of robot assistants were also considered for the review. Two authors independently identified the trials for inclusion and independently extracted the data. We calculated the risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI) using the fixed-effect and the random-effects models based on intention-to-treat analysis, when possible, using Review Manager 5. We included six trials with 560 patients. One trial involving 129 patients did not state the number of patients randomised to the two groups. In the remaining five trials 431 patients were randomised, 212 to the robot assistant group and 219 to the human assistant group. All the trials were at high risk of bias. Mortality and morbidity were reported in only one trial with 40 patients. There was no mortality or morbidity in either group. Mortality and morbidity were not reported in the remaining trials. Quality of life or the proportion of patients who were discharged as day-patient laparoscopic cholecystectomy patients were not reported in any

    Full Text Available The purpose of this paper is to identify learning in games in experimental economic settings, and apply their results to real multilateral trade negotiations, such as the Doha Development Agenda (DDA in the World Trade Organizations (WTO. This paper argues that the structure of games including a veto player (Veto games is similar to the WTO/DDA negotiations in that the players do not possess identical power. This paper's main contribution to the literature involves showing that learning about power is dominant over learning from simple repetition in Veto games. Additionally, this paper shows that players are concerned about how much they have gained in previous games in Veto games, although their memories generally do not last beyond the next game, and thus they tend to be selfish as they have less shares. Based on these results, there is a possibility to be more generous in the distribution of benefits by allowing players without veto power to retain special rights so that they would not be totally powerless. It also shows the necessity of having "respite" in the process of negotiations and policy options for choosing partners for winning coalitions.

    In the frame of the strong on-going data analysis effort of the CDF collaboration at Fermilab, a method was developed by the candidate to improve the background rejection efficiency in the search for associated pair production of electroweak W, Z bosons. The performaces of the method for vetoing the tt background in a WZ/ZZ → fνq$\\bar{q}$ diboson search are reported. The method was developed in the inclusive 2-jets sample and applied to the “tag-2 jets" region, the subsample defined by the request that the two jets carry beauty flavor. In this region the tt production is one of the largest backgrounds. The tt veto proceeds in two steps: first, a set of pre-selection cuts are applied in a candidate sample where up to two leptons are accepted in addition to a jet pair, and the ZZ component of the signal is thus preserved; next, a Neural Network is trained to indicate the probability that the event be top-pair production. To validate the the method as developed in the inclusive 2-jets sample, it is applied to veto region providing a significant rejection of this important background.

    Highlights: • Propose a fuel cell trigeneration system integrated with solar-assisted methanol reforming. • Optimize the reaction parameters of methanol steam reforming. • Present the energy and exergy analysis under design and off-design work conditions. • Analyze the contributions of solar energy to the trigeneration system. - Abstract: A solar-assisted trigeneration system for producing electricity, cooling, and heating simultaneously is an alternative scheme to improve energy efficiency and boost renewable energy. This paper proposes a phosphoric acid fuel cell trigeneration system integrated with methanol and steam reforming assisted by solar thermal energy. The trigeneration system consists of a solar heat collection subsystem, methanol steam reforming subsystem, fuel cell power generation subsystem, and recovered heat utilization subsystem. Their respective thermodynamic models are constructed to simulate the system input/output characteristics, and energy and exergy efficiencies are employed to evaluate the system thermodynamic performances. The contribution of solar energy to the system is analyzed using solar energy/exergy share. Through the simulation and analysis of methanol and steam reforming reactions, the optimal reaction pressure, temperature, and methanol to water ratio are obtained to improve the flow rate and content of produced hydrogen. The thermodynamic simulations of the trigeneration system show that the system energy efficiencies at the summer and winter design work conditions are 73.7% and 51.7%, while its exergy efficiencies are 18.8% and 26.1%, respectively. When the solar radiation intensity is different from the design work condition, the total energy and exergy efficiencies in winter decrease approximately by 4.7% and 2.2%, respectively, due to the decrease in solar heat collection efficiency. This proposed novel trigeneration system complemented by solar heat energy and methanol chemical energy is favorable for improving the

    The fluid dynamics of the Thoratec HeartMate III (Thoratec Corp., Pleasanton, CA, U.S.A.) left ventricular assist device are analyzed over a range of physiological operating conditions. The HeartMate III is a centrifugal flow pump with a magnetically suspended rotor. The complete pump was analyzed using computational fluid dynamics (CFD) analysis and experimental particle imaging flow visualization (PIFV). A comparison of CFD predictions to experimental imaging shows good agreement. Both CFD and experimental PIFV confirmed well-behaved flow fields in the main components of the HeartMate III pump: inlet, volute, and outlet. The HeartMate III is shown to exhibit clean flow features and good surface washing across its entire operating range.

    To investigate whether use of multiparametric magnetic resonance (MR) imaging-directed intraoperative frozen-section (IFS) analysis during nerve-sparing robot-assisted radical prostatectomy reduces the rate of positive surgical margins. This retrospective analysis of prospectively acquired data was approved by an institutional ethics committee, and the requirement for informed consent was waived. Data were reviewed for 134 patients who underwent preoperative multiparametric MR imaging (T2 weighted, diffusion weighted, and dynamic contrast-material enhanced) and nerve-sparing robot-assisted radical prostatectomy, during which IFS analysis was used, and secondary resections were performed when IFS results were positive for cancer. Control patients (n = 134) matched for age, prostate-specific antigen level, and stage were selected from a pool of 322 patients who underwent nerve-sparing robot-assisted radical prostatectomy without multiparametric MR imaging and IFS analysis. Rates of positive surgical margins were compared by means of the McNemar test, and a multivariate conditional logistic regression model was used to estimate the odds ratio of positive surgical margins for patients who underwent MR imaging and IFS analysis compared with control subjects. Eighteen patients who underwent MR imaging and IFS analysis underwent secondary resections, and 13 of these patients were found to have negative surgical margins at final pathologic examination. Positive surgical margins were found less frequently in the patients who underwent MR imaging and IFS analysis than in control patients (7.5% vs 18.7%, P = .01). When the differences in risk factors are taken into account, patients who underwent MR imaging and IFS had one-seventh the risk of having positive surgical margins relative to control patients (adjusted odds ratio: 0.15; 95% confidence interval: 0.04, 0.61). The significantly lower rate of positive surgical margins compared with that in control patients provides

    2006-01-01

    INIS has identified computer-assisted indexing as areas where information technology could assist best in maintaining database quality and indexing consistency, while containing production costs. Subject analysis is a very important but also very expensive process in the production of the INIS database. Given the current necessity to process an increased number of records, including subject analysis, without additional staff, INIS as well as the member states need improvements in their processing efficiency. Computer assisted subject analysis is a promising way to achieve this. The quality of the INIS database is defined by its inputting rules. The Thesaurus is a terminological control device used in translating from the natural language of documents, indexers or users into a more constrained system language. It is a controlled and dynamic vocabulary of semantically and generically related terms. It is the essential tool for subject analysis as well as for advanced search engines. To support the identification of descriptors in the free text (title, abstract, free keywords) 'hidden terms' have been introduced as extension of the Thesaurus, which identify phrases or character strings of free text and point to the valid descriptor, which should be suggested. In the process of computer-assisted subject analysis the bibliographic records (including title and abstract) are analyzed by the software, resulting in a list of suggested descriptors. Within the working platform (graphical user interface) the suggested descriptors are sorted by importance (by their relevance for the content of the document) and the subject specialist clearly sees the highlighted context from which the terms were selected. The system allows the subject specialist to accept or reject descriptors from the suggested list and to assign additional descriptors when necessary. First experiences show that a performance enhancement of about 80-100% can be achieved in the subject analysis process. (author)

    2016-09-01

    For a wider project on aging in prison, the authors interviewed 35 older prisoners and 24 stakeholders (prison staff, prison healthcare professionals, and policy makers) about healthcare for prisoners. In all, 6 prisoners and 3 stakeholders spontaneously expressed their attitudes concerning assisted suicide. Some prisoners seek assisted suicide for medical reasons and others because they regard spending the rest of their lives in prison as undignified. However, stakeholders identified several ethical and practical challenges in providing assisted suicide to prisoners. This article presents these perspectives on assisted suicide in prison and provides an ethical analysis of the issues raised.

    This article presents a simple, ultra-wideband and tunable radiofrequency (RF) converter for 5G cellular networks. The proposed optoelectronic device performs broadband photonics-assisted upconversion and downconversion using a single optical modulator. Experimental results demonstrate RF conversion from DC to millimeter waves, including 28 and 38 GHz that are potential frequency bands for 5G applications. Narrow linewidth and low phase noise characteristics are observed in all generated RF carriers. An experimental digital performance analysis using different modulation schemes illustrates the applicability of the proposed photonics-based device in reconfigurable optical wireless communications.

    This secondary data analysis explored factors influencing job satisfaction in a sample of nursing assistants employed in Maryland skilled nursing facilities. Multiple factors have been shown to affect job satisfaction and turnover in nursing assistants (NAs), but the problem of turnover persists in skilled nursing facility environments affecting quality of care. An existing data set of 556 nursing assistants from 12 Maryland skilled nursing facilities was used. To explore factors found to influence job satisfaction from other studies, a multiple regression analysis was performed. Nine dependent variables previously shown to affect job satisfaction were used. Of these variables, only years of experience (β = .230) and performance of restorative care (β = .095) were found to be positively associated with job satisfaction. Self-esteem (β = -.094) was found to be negatively associated with job satisfaction. Only length of experience and exemplary care as evidenced by the performance of restorative care were associated with job satisfaction. These results mirror results found in other studies. Self-esteem was negatively associated with job satisfaction in this population, a finding needing further study. Copyright © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins

    Professional burnout and work-related stress are known problems that have been the subject of in-depth examination among dentists. Nevertheless, these issues have not been widely studied among dental assistants. The aims of this study were threefold: to confirm the structure of a Work Stress Inventory (WSI) for Dental Assistants which was originally developed for Jordanian dental assistants (factor analysis); to evaluate work stress and burnout among Israeli dental assistants and to discover the factors predicting Israeli assistants' burnout (regression analyses). The Maslach Burnout Inventory and the WSI were distributed by mail and in person. Varimax factor analysis revealed that the items which contribute to different aspects of work stress are similar among both Jordanian and Israeli populations. Among the 299 Israeli dental assistants who completed the questionnaires, the most stressful work-related factors were income, workload, and work hazards. Eighteen percent of the participants exhibited a high to very high level of burnout. Participants exhibited a moderate level of emotional exhaustion (EE), low level of depersonalization (DP), and high level of personal accomplishment (PA). Most WSI factors were found to correlate positively with EE and DP. Linear stepwise regression analyses revealed that the best predictor of EE was the dentist‒assistant relationship, followed by workload, patient type, and salary. The best predictor of DP was patient suffering followed by dentist‒assistant relationship, years of professional experience, and work hazards. Professional stress and burnout among dental assistants are important factors that can possibly affect the wellbeing of both dental personnel and their patients. Further studies are necessary to better understand these factors in addition to the effects of personal relationships on burnout among dentists and their assistants.

    We have fabricated by e-beam lithography periodic arrays of rectangular shaped trenches of different widths into Si substrates. The trenches were filled with iron oxide nanoparticles, 20 nm in diameter, by spin-coating them onto the Si substrate. The trenches have the purpose to assist the self-assembly of the iron oxide nanoparticles. Using x-ray scattering techniques, we have analyzed the structure factor of the trenches before and after filling in order to determine the filling factor. We present a theoretical analysis of the x-ray scattering function within the distorted-wave Born approximation and we present a quantitative comparison between theory and experiment.

    To perform a meta-analysis on the precision and safety of femtosecond laser-assisted anterior capsulotomy versus conventional manual continuous curvilinear capsulorrhexis. This meta-analysis was conducted from February 2010 to November 2014. Literature search on PubMed, Google Scholar, ExcerptaMedica database and Cochrane Library was done to identify randomised controlled trials and case-control studies. SPSS 20 was used for data analysis. Of the 10 articles included, there were 3(30%) randomised controlled trials and 7(70%) non-randomised controlled trials. The meta-analysis was based on a total of 2,882eyes. Of them, 1,498(51.97%) underwent femtosecond laser-assisted capsulotomy and 1,384(48.02%) underwent manual continuous curvilinear capsulorrhexis. The diameter of the capsulotomy and the rates of anterior capsule tear showed no statistical difference between the femtosecond laser group and the manual capsulorrhexis group (p=0.29 and p=0.68). In terms of circularity of capsulotomy, femtosecond laser group had a more significant advantage than the manual capsulorrhexis group (pmanual continuous curvilinear capsulorrhexis.

    This paper shows a Multi objective Analysis (AMO-ELECTRE 111) with Geographical Information System (GIS) to establish priorities of buffer zones on the drainage network of the Santa Elena Creek, Medellin middle-east zone. 38 alternatives (small catchment) are evaluated with seven criteria, from field work, and maps. The criteria are: susceptibility to mass sliding, surface and lineal erosion, conflict by land use, and state of the waterways network in respect to hydrology, geology and human impact. The ELECTERE III method allows establishing priorities of buffer zones for each catchment; the indifference, acceptance, veto, and credibility threshold values, as well as those for criteria weighting factors are very important. The results show that the north zone of the catchment, commune 8, in particular La Castro creek, is most affected. The sensibility analysis shows that the obtained solution is robust, and that the anthropic and geologic criteria are paramount

    2010-09-01

    Controlled hydrolysis of proteins to generate peptide ladders combined with mass spectrometric analysis of the resultant peptides can be used for protein sequencing. In this paper, two methods of improving the microwave-assisted protein hydrolysis process are described to enable rapid sequencing of proteins containing disulfide bonds and increase sequence coverage, respectively. It was demonstrated that proteins containing disulfide bonds could be sequenced by MS analysis by first performing hydrolysis for less than 2 min, followed by 1 h of reduction to release the peptides originally linked by disulfide bonds. It was shown that a strong base could be used as a catalyst for microwave-assisted protein hydrolysis, producing complementary sequence information to that generated by microwave-assisted acid hydrolysis. However, using either acid or base hydrolysis, amide bond breakages in small regions of the polypeptide chains of the model proteins (e.g., cytochrome c and lysozyme) were not detected. Dynamic light scattering measurement of the proteins solubilized in an acid or base indicated that protein-protein interaction or aggregation was not the cause of the failure to hydrolyze certain amide bonds. It was speculated that there were some unknown local structures that might play a role in preventing an acid or base from reacting with the peptide bonds therein. 2010 American Society for Mass Spectrometry.

    2013-01-01

    Full Text Available Research assistantships have long been viewed as an extension of the formal education process, a form of apprenticeship, and a pathway into the professional practice of research in institutional settings. However, there are other contexts in which researchers practice research. This self-study documents the formative role research assistantships played in the authors’ development as professional research consultants. Four professional research consultants who held research assistant positions during their master’s and doctoral studies describe the contributions of their research assistantship experiences to the advancement of their knowledge, skills, and passion for research and subsequently to their career decisions. Professional research consulting is identified as a natural extension of research assistant roles and a potential career path. The article enhances current understandings about the ways research assistantships contribute to the development of researchers, and specifically to the development of professional research consultants. The analysis will be of interest to students contemplating entering into research assistantships, current research assistants, current research assistant supervisors, academic staff looking to improve their research productivity, and department chairs.

  12. Navigating "Assisted Dying".

    Schipper, Harvey

    2016-02-01

    Carter is a bellwether decision, an adjudication on a narrow point of law whose implications are vast across society, and whose impact may not be realized for years. Coupled with Quebec's Act Respecting End-of-life Care it has sharply changed the legal landscape with respect to actively ending a person's life. "Medically assisted dying" will be permitted under circumstances, and through processes, which have yet to be operationally defined. This decision carries with it moral assumptions, which mean that it will be difficult to reach a unifying consensus. For some, the decision and Act reflect a modern acknowledgement of individual autonomy. For others, allowing such acts is morally unspeakable. Having opened the Pandora's Box, the question becomes one of navigating a tolerable societal path. I believe it is possible to achieve a workable solution based on the core principle that "medically assisted dying" should be a very rarely employed last option, subject to transparent ongoing review, specifically as to why it was deemed necessary. My analysis is based on 1. The societal conditions in which have fostered demand for "assisted dying", 2. Actions in other jurisdictions, 3. Carter and Quebec Bill 52, 4. Political considerations, 5. Current medical practice. Leading to a series of recommendations regarding. 1. Legislation and regulation, 2. The role of professional regulatory agencies, 3. Medical professions education and practice, 4. Public education, 5. Health care delivery and palliative care. Given the burden of public opinion, and the legal steps already taken, a process for assisted-dying is required. However, those legal and regulatory steps should only be considered a necessary and defensive first step in a two stage process. The larger goal, the second step, is to drive the improvement of care, and thus minimize assisted-dying.

  13. Aero-Assisted Pre-Stage for Ballistic and Aero-Assisted Launch Vehicles

    Ustinov, Eugene A.

    2012-01-01

    A concept of an aero-assisted pre-stage is proposed, which enables launch of both ballistic and aero-assisted launch vehicles from conventional runways. The pre-stage can be implemented as a delta-wing with a suitable undercarriage, which is mated with the launch vehicle, so that their flight directions are coaligned. The ample wing area of the pre-stage combined with the thrust of the launch vehicle ensure prompt roll-out and take-off of the stack at airspeeds typical for a conventional jet airliner. The launch vehicle is separated from the pre-stage as soon as safe altitude is achieved, and the desired ascent trajectory is reached. Nominally, the pre-stage is non-powered. As an option, to save the propellant of the launch vehicle, the pre-stage may have its own short-burn propulsion system, whereas the propulsion system of the launch vehicle is activated at the separation point. A general non-dimensional analysis of performance of the pre-stage from roll-out to separation is carried out and applications to existing ballistic launch vehicle and hypothetical aero-assisted vehicles (spaceplanes) are considered.

    The present clinical study describes a method of evaluation of Paget's disease bone by computer assisted analysis of activity curves obtained over normal and pathological portions of the skeleton in the same patient. The data obtained lead to a differential diagnosis between Paget's and metastatic disease of the bone, as well as an evaluation of subsequent therapy. The results indicate a higher bone activity, (expressed by bone flow and bone uptake, of sup(99m)Tc pyrophosphate) in Paget's than in metastatic disease of the bone, as well as a normalization of these parameters after prolonged therapy of Paget's patients with salmon calcitonin

    To report the 5-year oncological outcomes of robot-assisted radical prostatectomy from the largest series ever reported from Asia. A retrospective analysis of 800 Asian patients who were treated with robot-assisted radical prostatectomy from July 2005 to May 2010 in the Department of Urology and Urological Science Institute, Yonsei University College of Medicine, Seoul, Korea was carried out. The primary end-point was to evaluate the biochemical recurrence. The secondary end-point was to show the biochemical recurrence-free survival, metastasis-free survival and cancer-specific survival. A total of 197 (24.65%), 218 (27.3%), and 385 (48.1%) patients were classified as low-, intermediate- and high-risk patients according to the D'Amico risk stratification risk criteria, respectively. The median follow-up period was 64 months (interquartile range 28-71 months). The overall incidence of positive surgical margin was 36.6%. There was biochemical recurrence in 183 patients (22.9%), 38 patients (4.8%) developed distant metastasis and 24 patients (3%) died from prostate cancer. Actuarial biochemical recurrence-free survival, metastasis-free survival, and cancer-specific survival rates at 5 years were 76.4%, 94.6% and 96.7%, respectively. Positive lymph node was associated with lower 5-year biochemical recurrence-free survival (9.1%), cancer-specific survival (75.7%) and metastasis-free survival (61.9%) rates (P < 0.001). On multivariable analysis, among all the predictors, positive lymph node was the strongest predictor of biochemical recurrence, cancer-specific survival and metastasis-free survival (P < 0.001). Herein we report the largest robot-assisted radical prostatectomy series from Asia. Robot-assisted radical prostatectomy is confirmed to be an oncologically safe procedure that is able to provide effective 5-year cancer control, even in patients with high-risk disease. © 2016 The Japanese Urological Association.

    In the U.S., there are federal requirements on how much training and annual continuing education a certified nursing assistant must complete in order to be certified. The requirements are designed to enable them to provide competent and quality care to nursing home residents. Many states also require additional training and continuing education hours as improved nursing home quality indicators have been found to be related to increased training. This study investigated the associations among state level regulations, initial training quality and focus, and job satisfaction in certified nursing assistants. Cross-sectional secondary data analysis. This study used the National Nursing Home Survey and National Nursing Assistant Survey as well as data on state regulations of certified nursing assistant training. 2897 certified nursing assistants in 580 nursing homes who were currently working at a nursing home facility, who represented 680,846 certified nursing assistants in US. State regulations were related to initial training and job satisfaction among certified nursing assistants using chi square tests and binomial logistic regression models. Analyses were conducted using SAS-callable SUDAAN to correct for complex sampling design effects in the National Nursing Home Survey and National Nursing Assistant Survey. Models were adjusted for personal and facility characteristics. Certified nursing assistants reporting high quality training were more likely to work in states requiring additional initial training hours (p=0.02) and were more satisfied with their jobs (OR=1.51, 95% CI=1.09-2.09) than those with low quality training. In addition, those with more training focused on work life skills were 91% more satisfied (OR=1.91, 95% CI=1.41-2.58) whereas no relationship was found between training focused on basic care skills and job satisfaction (OR=1.36, 95% CI=0.99-1.84). Certified nursing assistants with additional initial training were more likely to report that their

    An innovative preparation procedure, based on microwave assisted non-hydrolytic sol–gel synthesis, to obtain spherical magnetite nanoparticles was reported together with a detailed quantitative phase analysis and microstructure characterization of the synthetic products. The nanoparticle growth was analyzed as a function of the synthesis time and was described in terms of crystallization degree employing the Rietveld method on the magnetic nanostructured system for the determination of the amorphous content using hematite as internal standard. Product crystallinity increases as the microwave thermal treatment is increased and reaches very high percentages for synthesis times longer than 1 h. Microstructural evolution of nanocrystals was followed by the integral breadth methods to obtain information on the crystallite size-strain distribution. The results of diffraction line profile analysis were compared with nanoparticle grain distribution estimated by dimensional analysis of the transmission electron microscopy (TEM) images. A variation both in the average grain size and in the distribution of the coherently diffraction domains is evidenced, allowing to suppose a relationship between the two quantities. The traditional integral breadth methods have proven to be valid for a rapid assessment of the diffraction line broadening effects in the above-mentioned nanostructured systems and the basic assumption for the correct use of these methods are discussed as well. - Highlights: • Fe{sub 3}O{sub 4} nanocrystals were obtained by MW-assisted non-hydrolytic sol–gel synthesis. • Quantitative phase analysis revealed that crystallinity up to 95% was reached. • The strategy of Rietveld refinements was discussed in details. • Dimensional analysis showed nanoparticles ranging from 4 to 8 nm. • Results of integral breadth methods were compared with microscopic analysis.

    For an employee with a disability, reasonable accommodation can make the difference in finding work, maintaining employment, and succeeding on the job. Today, employers and employees alike are more aware that appropriate accommodation, including workplace personal assistance services (PAS) as well as assistive technology, improves an employee's ability to succeed. While assistive technology is in widespread use as an accommodation, workplace personal assistance is less understood. The goal of the study was to learn more about how workplace PAS and AT are arranged for in the workplace, and the issues that arise. Structured phone interviews were conducted with 20 workplace PAS users, 21 employers familiar with workplace PAS, and 19 employment organizations. Interview transcripts are the basis for the qualitative analysis of findings. Requirements for personal assistance accommodations focus on task-related needs. Personal care needs at work are not included in the Americans with Disabilities act but may be needed by the employee. Employers and PAS users have developed many creative ways to address PAS need. Organizations can construct an approach that fits the needs, abilities, and constraints of each organization. The interview respondents have identified a number of practices that are succeeding, including establishment of policies for arranging for PAS; centralization of accommodation budgets to remove work unit disincentives; and providing a shared personal assistant for interpreting or for task-related and personal care tasks. A number of important research questions remain. What is the extent of the need for PAS in the workplace? Will an expanded PAS supply increase the employment opportunities for people with disabilities? Will better models of workplace PAS be adopted by employers?

    With the increase of life expectancy, a higher number of elderly need assistance to maintain their mobility and their independance. The hip joint is crucial for walking and is problematic for a large number of aged people. In this paper we present a novel design of a motorized hip orthosis to assist elderly people while walking, stair climbing and during the sit-to-stand transistions. The kinematics was developed based on biomechanics considerations. To be able to achieve a large assistance rate, velocity and torques of the hip joint were studied from the literature. In order to fit with these requirements, an amplification mechanism inspired by excavators was developed and implemented. Comfort considerations were also taken into account and a custom interface was designed with the collaboration of a professional orthopaedic technician. First tests with the prototype showed that the workspace is sufficient for walking, for stair climbing as well as for sit-to-stand transitions. The assistance rate can go up to 30% for a 70 kg subject during walking at a cadence of 100 steps/min. The comfort is guaranteed despite the important weight (4.3 kg) of this first prototype.

  1. Ceria nanocubic-ultrasonication assisted dispersive liquid-liquid microextraction coupled with matrix assisted laser desorption/ionization mass spectrometry for pathogenic bacteria analysis.

    2014-03-01

    A new ceria (CeO2) nanocubic modified surfactant is used as the basis of a novel nano-based microextraction technique for highly sensitive detection of pathogenic bacteria (Pseudomonas aeruginosa and Staphylococcus aureus). The technique uses ultrasound enhanced surfactant-assisted dispersive liquid-liquid microextraction (UESA-DLLME) with and without ceria (CeO2) followed by matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS). In order to achieve high separation efficiency, we investigated the influential parameters, including extraction time of ultrasonication, type and volume of the extraction solvent and surfactant. Among various surfactants, the cationic surfactants can selectively offer better extraction efficiency on bacteria analysis than that of the anionic surfactants due to the negative charges of bacteria cell membranes. Extractions of the bacteria lysate from aqueous samples via UESA-DLLME-MALDI-MS were successfully achieved by using cetyltrimethyl ammonium bromide (CTAB, 10.0 µL, 1.0×10(-3) M) as surfactants in chlorobenzene (10.0 µL) and chloroform (10.0 µL) as the optimal extracting solvent for P. aeruginosa and S. aureus, respectively. Ceria nanocubic was synthesized, and functionalized with CTAB (CeO2@CTAB) and then characterized using transmission electron microscopy (TEM) and optical spectroscopy (UV and FTIR). CeO2@CTAB demonstrates high extraction efficiency, improve peaks ionization, and enhance resolution. The prime reasons for these improvements are due to the large surface area of nanoparticles, and its absorption that coincides with the wavelength of MALDI laser (337 nm, N2 laser). CeO2@CTAB-based microextraction offers lowest detectable concentrations tenfold lower than that of without nanoceria. The present approach has been successfully applied to detect pathogenic bacteria at low concentrations of 10(4)-10(5) cfu/mL (without ceria) and at 10(3)-10(4) cfu/mL (with ceria) from bacteria suspensions. Finally, the

    Full Text Available Assistive robots have a great potential to address issues related to an aging population and an increased demand for caregiving. Successful deployment of robots working in close proximity with people requires consideration of both safety and human–robot interaction (HRI. One of the established activities of daily living where robots could play an assistive role is dressing. Using the correct force profile for robot control will be essential in this application of HRI requiring careful exploration of factors related to the user’s pose and the type of garments involved. In this paper, a Baxter robot was used to dress a jacket onto a mannequin and human participants considering several combinations of user pose and clothing type (base layers, while recording dynamic data from the robot, a load cell, and an IMU. We also report on suitability of these sensors for identifying dressing errors, e.g., fabric snagging. Data were analyzed by comparing the overlap of confidence intervals to determine sensitivity to dressing. We expand the analysis to include classification techniques such as decision tree and support vector machines using k-fold cross-validation. The 6-axis load cell successfully discriminated between clothing types with predictive model accuracies between 72 and 97%. Used independently, the IMU and Baxter sensors were insufficient to discriminate garment types with the IMU showing 40–72% accuracy, but when used in combination this pair of sensors achieved an accuracy similar to the more expensive load cell (98%. When observing dressing errors (snagging, Baxter’s sensors and the IMU data demonstrated poor sensitivity but applying machine learning methods resulted in model with high predicative accuracy and low false negative rates (≤5%. The results show that the load cell could be used independently for this application with good accuracy but a combination of the lower cost sensors could also be used without a significant loss in

    In this paper, the results of performance analysis of a ground-assisted hybrid evaporative cooling system in Tehran have been discussed. A Ground Coupled Circuit (GCC) provides the necessary pre-cooling effects, enabling a Direct Evaporative Cooler (DEC) that cools the air even below its wet-bulb temperature. The GCC includes four vertical ground heat exchangers (GHE) which were arrayed in series configuration. In order to have an accurate prediction of the optimum performance of a GCC, a computational fluid dynamic simulation was performed. Simulation results revealed that the combination of GCC and DEC system could provide comfort condition whereas DEC alone did not. Based on the simulation results the cooling effectiveness of a hybrid system is more than 100%. Thus, this novel hybrid system could decrease the air temperature below the ambient wet-bulb temperature. This environmentally clean and energy efficient system can be considered as an alternative to the mechanical vapor compression systems. (author)

    Full Text Available Assisted reproductive technology (ART has grown by leaps and bounds in the last few years. India has one of the highest growths in the ART centers and the number of ART cycles performed every year. Very soon India will be the leader in the world of ART in terms of a number of cycles. With the advances of technology and availability of techniques even in tier II and tier III cities our country, the results still vary dramatically. There is no standardization of protocols and reporting is very inadequate. Furthermore, there are only ART guidelines and no law still exists. Our first and the biggest challenge is to document the tremendous work being done in India and on the basis of analysis of this work, a proper registry can be made and guidance given to all on standardization and improvement. This is the 8 th edition of National ART Registry of India being presented and analyzed.

    A novel infrared-assisted extraction coupled to headspace solid-phase microextraction followed by gas chromatography with mass spectrometry method has been developed for the rapid determination of the volatile components in tobacco. The optimal extraction conditions for maximizing the extraction efficiency were as follows: 65 μm polydimethylsiloxane-divinylbenzene fiber, extraction time of 20 min, infrared power of 175 W, and distance between the infrared lamp and the headspace vial of 2 cm. Under the optimum conditions, 50 components were found to exist in all ten tobacco samples from different geographical origins. Compared with conventional water-bath heating and nonheating extraction methods, the extraction efficiency of infrared-assisted extraction was greatly improved. Furthermore, multivariate analysis including principal component analysis, hierarchical cluster analysis, and similarity analysis were performed to evaluate the chemical information of these samples and divided them into three classifications, including rich, moderate, and fresh flavors. The above-mentioned classification results were consistent with the sensory evaluation, which was pivotal and meaningful for tobacco discrimination. As a simple, fast, cost-effective, and highly efficient method, the infrared-assisted extraction coupled to headspace solid-phase microextraction technique is powerful and promising for distinguishing the geographical origins of the tobacco samples coupled to suitable chemometrics. © 2016 WILEY-VCH Verlag GmbH & Co.

    Highlights: ► Chemometrics-assisted EDXRFS spectroscopy realizes direct, rapid and accurate analysis of trace bioavailable macronutrients in soils. ► The method is minimally invasive, involves little sample preparation, short analysis times and is relatively insensitive to matrix effects. ► This opens up the ability to rapidly characterize large number of samples/matrices with this method. - Abstract: Precision agriculture depends on the knowledge and management of soil quality (SQ), which calls for affordable, simple and rapid but accurate analysis of bioavailable soil nutrients. Conventional SQ analysis methods are tedious and expensive. We demonstrate the utility of a new chemometrics-assisted energy dispersive X-ray fluorescence and scattering (EDXRFS) spectroscopy method we have developed for direct rapid analysis of trace ‘bioavailable’ macronutrients (i.e. C, N, Na, Mg, P) in soils. The method exploits, in addition to X-ray fluorescence, the scatter peaks detected from soil pellets to develop a model for SQ analysis. Spectra were acquired from soil samples held in a Teflon holder analyzed using 109 Cd isotope source EDXRF spectrometer for 200 s. Chemometric techniques namely principal component analysis (PCA), partial least squares (PLS) and artificial neural networks (ANNs) were utilized for pattern recognition based on fluorescence and Compton scatter peaks regions, and to develop multivariate quantitative calibration models based on Compton scatter peak respectively. SQ analyses were realized with high CMD (R 2 > 0.9) and low SEP (0.01% for N and Na, 0.05% for C, 0.08% for Mg and 1.98 μg g −1 for P). Comparison of predicted macronutrients with reference standards using a one-way ANOVA test showed no statistical difference at 95% confidence level. To the best of the authors’ knowledge, this is the first time that an XRF method has demonstrated utility in trace analysis of macronutrients in soil or related matrices.

    This study was designed to determine the ability of computer-assisted sperm morphometry analysis (CASA-Morph) with fluorescence to discriminate between spermatozoa carrying different sex chromosomes from the nuclear morphometrics generated and different statistical procedures in the bovine species. The study was divided into two experiments. The first was to study the morphometric differences between X- and Y-chromosome-bearing spermatozoa (SX and SY, respectively). Spermatozoa from eight bulls were processed to assess simultaneously the sex chromosome by FISH and sperm morphometry by fluorescence-based CASA-Morph. SX cells were larger than SY cells on average (P potential to find differences between X- and Y-chromosome-bearing spermatozoa in bovine species although more studies are needed to increase the precision of sex determination by this technique.

    The study aimed at analyzing four proposals of obstetric assistance that co-existed in the city of Rio de Janeiro from the early Thirties to the Fifties, as well as discussing the inclusion of graduated and non-graduated accoucheuses, and nurses. It is of a historical-social nature, making use of the written document as a primary source. The analysis is based Pierre Bourdieu's main concepts. With this research, it was possible to make evident the domiciliary obstetric service of the sanitarist model, the philanthropic proposal of society's ladies, the individualized hospital-based assistance, and the proposal of integrated obstetric assistance. The study also allowed the understanding of the exclusion of non-graduated women from the Brazilian obstetric field.

    Stable isotope assisted metabolomics (SIAM) measures the abundance levels of metabolites in a particular pathway using stable isotope tracers (e.g., 13 C, 18 O and/or 15 N). We report a method termed signature ion approach for analysis of SIAM data acquired on a GC-MS system equipped with an electron ionization (EI) ion source. The signature ion is a fragment ion in EI mass spectrum of a derivatized metabolite that contains all atoms of the underivatized metabolite, except the hydrogen atoms lost during derivatization. In this approach, GC-MS data of metabolite standards were used to recognize the signature ion from the EI mass spectra acquired from stable isotope labeled samples, and a linear regression model was used to deconvolute the intensity of overlapping isotopologues. A mixture score function was also employed for cross-sample chromatographic peak list alignment to recognize the chromatographic peaks generated by the same metabolite in different samples, by simultaneously evaluating the similarity of retention time and EI mass spectrum of two chromatographic peaks. Analysis of a mixture of 16 13 C-labeled and 16 unlabeled amino acids showed that the signature ion approach accurately identified and quantified all isotopologues. Analysis of polar metabolite extracts from cells respectively fed with uniform 13 C-glucose and 13 C-glutamine further demonstrated that this method can also be used to analyze the complex data acquired from biological samples. - Highlights: • A signature ion approach is developed for analysis of stable isotope GC-MS data. • GC-MS data of compound standards are used for selection of the signature ion. • Linear regression model is used to deconvolute the overlapping isotopologue peaks. • The developed method was tested by known compounds and biological samples.

    Robotic-assisted laparoscopic surgery is an emerging modality in the field of minimally invasive colorectal surgery. However, there is a dearth of data comparing outcomes with other minimally invasive techniques. We present a 3-arm (conventional, hand-assisted, and robotic) matched-case analysis of intraoperative and short-term outcomes in patients undergoing minimally invasive colorectal procedures. Between August 2008 and October 2009, 70 robotic cases of the rectum and rectosigmoid were performed. Thirty of these were organized into triplets with conventional and hand-assisted cases based on the following 6 matching criteria: 1) surgeon; 2) sex; 3) body mass index; 4) operative procedure; 5) pathology; and 6) history of neoadjuvant therapy in malignant cases. Demographics, intraoperative parameters, and postoperative outcomes were assessed. Pathological outcomes were analyzed in malignant cases. Data were stratified by postoperative diagnosis and operative procedure. There was no significant difference in intraoperative complications, estimated blood loss (126.1 ± 98.5 mL overall), or postoperative morbidity and mortality among the groups. Robotic technique required longer operative time compared with conventional laparoscopic (P hand-assisted (P robotic approach results in short-term outcomes comparable to conventional and hand-assisted laparoscopic approaches for benign and malignant diseases of the rectum and rectosigmoid. With 3-dimensional visualization, additional freedom of motion, and improved ergonomics, this enabling technology may play an important role when performing colorectal procedures involving the pelvic anatomy.

    When added to a mixed lymphocyte culture, bone marrow cells suppress the generation of CTL activity against H-2 Ag shared by the BM cells and the stimulator cells. These cells have been referred to as veto cells and are thought to play a role in maintaining self-tolerance. We analyzed the H-2 specificity of the suppression expressed by the veto cells from H-2 incompatible bone marrow chimeras, because lymphocytes of such chimeras had been shown to be tolerant to both donor and recipient Ag when tested by CTL responses. We found that the bone marrow cells of such chimeras which were featured by non-T and non-B cell characteristics inhibited the generation of CTL directed against either donor or recipient Ag, but not against third-party Ag. These observations suggest that in allogeneic chimeras the veto or veto-like cells alter the inhibitory specificity exhibited in the recipient microenvironment and indicate that these cells are directly involved in the induction and maintenance of self-tolerance

    Full Text Available The Body sensor network [IEEE 802.15] is a wireless communication network consisting of assistive devices which are of prime importance in medical applications. The delay critical and power hungry blocks in these assistive devices are designed so that they consume less power, have low latency and require a lesser area on chip. In this paper, we present a qualitative as well as a quantitative analysis of an asynchronous pipelined adder design with two latest computation completion sensing approaches based on Pseudo NMOS logic and other based on C-element. The Pseudo NMOS based completion sensing approach provides a maximum improvement of 76.92% in critical path delay at supply voltage of 1.2 V and the maximum drop in power dissipation has been observed at a supply voltage of 1.1 V which is 85.60% as compared to C-element based completion sensing approach. Even at low voltages such as 0.8 V, there is a significant improvement in speed and power which is 75.64% and 74.79% respectively. Since the adder is the most widely used component in all present day assistive devices, this analysis acts as a pointer for the application of asynchronous pipelined circuits with efficient Pseudo NMOS based completion sensing approach in low voltage/low power rehabilitative devices.

    Building on the successful experience in operating the DarkSide-50 detector, the DarkSide Collaboration is going to construct DarkSide-20k, a direct WIMP search detector using a two-phase Liquid Argon Time Projection Chamber (LAr TPC) with an active (fiducial) mass of 23 t (20 t). This paper describes a preliminary design for the experiment, in which the DarkSide-20k LAr TPC is deployed within a shield/veto with a spherical Liquid Scintillator Veto (LSV) inside a cylindrical Water Cherenkov Veto (WCV). This preliminary design provides a baseline for the experiment to achieve its physics goals, while further development work will lead to the final optimization of the detector parameters and an eventual technical design. Operation of DarkSide-50 demonstrated a major reduction in the dominant 39Ar background when using argon extracted from an underground source, before applying pulse shape analysis. Data from DarkSide-50, in combination with MC simulation and analytical modeling, shows that a rejection factor for discrimination between electron and nuclear recoils of >3 × 109 is achievable. This, along with the use of the veto system and utilizing silicon photomultipliers in the LAr TPC, are the keys to unlocking the path to large LAr TPC detector masses, while maintaining an experiment in which less than < 0.1 events (other than ν-induced nuclear recoils) is expected to occur within the WIMP search region during the planned exposure. DarkSide-20k will have ultra-low backgrounds than can be measured in situ, giving sensitivity to WIMP-nucleon cross sections of 1.2 × 10^{-47} cm2 (1.1 × 10^{-46} cm2) for WIMPs of 1 TeV/c 2 (10 TeV/c 2) mass, to be achieved during a 5 yr run producing an exposure of 100 t yr free from any instrumental background.

    Full Text Available We study the performance of the secondary relay system in a power-beacon (PB assisted energy harvesting cognitive relay wireless network. In our system model, a secondary source node and a relay node first harvest energy from distributed PBs. Then, the source node transmits its data to the destination node with the help of the relay node. Also, fading coefficients of the links from the PBs to the source node and relay node are assumed independent but not necessarily identically distributed (i.n.i.d Nakagami-m random variables. We derive exact expressions for the power outage probability and the channel outage probability. Based on that, we analyze the total outage probability of the secondary relay system. Asymptotic analysis is also performed, which provides insights into the system behavior. Moreover, we evaluate impacts of the primary network on the performance of the secondary network with respect to the tolerant interference threshold at the primary receiver as well as the interference introduced by the primary transmitter at the secondary source and relay nodes. Simulation results are provided to validate the analysis.

    Since the first use of robotic surgical system in 2000, the robot-assisted technology has gained wide popularity throughout the world. Robot-assisted surgical training is a complex issue that requires significant efforts from students and teacher. During the last two decades, simulation-based training had received active development due to wide-spread occurrence and popularization of laparoscopic and robot-assisted surgical techniques. We performed a systematic review to identify the currently available simulators for robot-assisted surgery. We searched the Medline and Pubmed, English sources of literature data, using the following key words and phrases: "robotics", "robotic surgery", "computer assisted surgery", "simulation", "computer simulation", "virtual reality", "surgical training", and "surgical education". There were identified 565 publications, which meet the key words and phrases; 19 publications were selected for the final analysis. It was established that simulation-based training is the most promising teaching tool that can be used in the training of the next generation robotic surgeons. Today the use of simulators to train surgeons is validated. Price of devices is an obvious barrier for inclusion in the program for training of robotic surgeons, but the lack of this tool will result in a sharp increase in the duration of specialists training.

    This study examined characteristics of referrals to employee assistance programs (EAP) associated with subsequent termination of employment. As well, relationships between characteristics of the referrals and program characteristics were explored. Longitudinal data were collected at several time periods for 163 referrals to EAPs from five organizations. Survival analysis was conducted to determine which variables were associated with termination of employment. Females, cohabitating couples, and employees who worked for the organization for 5 or more years were most likely to remain employed. One interesting finding was that people with alcohol problems were significantly more likely to be formal referrals.

    Microwave assisted extraction (MAE) technique was employed for the extraction of pectin from dragon fruit peel. The extracting parameters were optimized by using four-variable-three-level Box-Behnken design (BBD) coupled with response surface methodology (RSM). RSM analysis indicated good correspondence between experimental and predicted values. 3D response surface plots were used to study the interactive effects of process variables on extraction of pectin. The optimum extraction conditions for the maximum yield of pectin were power of 400 W, temperature of 45 °C, extracting time of 20 min and solid-liquid ratio of 24 g/mL. Under these conditions, 7.5% of pectin was extracted. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available O termo "humanização" tem sido empregado constantemente no âmbito da saúde. É a base de um amplo conjunto de iniciativas, mas não possui uma definição mais clara, geralmente designando a forma de assistência que valoriza a qualidade do cuidado do ponto de vista técnico, associada ao reconhecimento dos direitos do paciente, de sua subjetividade e cultura, além do reconhecimento do profissional. Tal conceito pretende-se norteador de uma nova práxis na produção do cuidado em saúde. Este artigo, de cunho exploratório, visa analisar o discurso do Ministério da Saúde sobre a humanização da assistência. Investigamos os sentidos e expectativas associados à idéia de humanização a partir da análise dos textos oficiais, retomando um diálogo crítico com os autores da área de saúde pública e das ciências sociais. Discutimos as idéias centrais da humanização como oposição à violência; oferta de atendimento de qualidade, articulando os avanços tecnológicos com acolhimento, melhoria das condições de trabalho do profissional, e ampliação do processo comunicacional, eixo central dos textos.The term "humanization" has been employed constantly in the health field.

    Selection of assistive technology for young children is a complex process. Within a context with limited resources, such as South Africa, research is needed to determine the factors influencing the assistive technology selection process, as these could ultimately either facilitate or hinder the availability and accessibility of affordable, adaptable, acceptable, and high quality assistive technology for this age group. Two asynchronous online focus groups were conducted with 16 rehabilitation professionals to identify the factors they perceived to influence the selection and provision of assistive technology to young children within the South African context. A process of deductive thematic analysis was followed by inductive analysis of the data. Components of the Assistive Technology Device Selection Framework were used as themes to guide the deductive analysis, followed by inductive analysis to create subthemes. The important role of the professional was highlighted in negotiating all the factors to consider in the assistive technology selection and provision process. Adaptation of the Assistive Technology Device Selection Framework is suggested in order to facilitate application to low resourced contexts, such as South Africa. Implications for rehabilitation Assistive technology selection is a complex process with factors pertaining to the users (child and family) of the assistive technology, as well as the rehabilitation professional recommending the assistive technology influencing the process. Although it may be an important factor, the availability of financial resources to purchase assistive technology is not the only determining factor in providing appropriate assistive technology to young children in contexts with limited resources. Formalized support, such as reflective supervision or mentorship programs should be facilitated and utilized by recommending professionals. Home and school visits during assessment ensure a good match between assistive

    Powered exoskeletons are designed to safely facilitate ambulation in patients with spinal cord injury (SCI). We conducted the first meta-analysis of the available published research on the clinical effectiveness and safety of powered exoskeletons in SCI patients. MEDLINE and EMBASE databases were searched for studies of powered exoskeleton-assisted walking in patients with SCI. Main outcomes were analyzed using fixed and random effects meta-analysis models. A total of 14 studies (eight ReWalk™, three Ekso™, two Indego(®), and one unspecified exoskeleton) representing 111 patients were included in the analysis. Training programs were typically conducted three times per week, 60-120 minutes per session, for 1-24 weeks. Ten studies utilized flat indoor surfaces for training and four studies incorporated complex training, including walking outdoors, navigating obstacles, climbing and descending stairs, and performing activities of daily living. Following the exoskeleton training program, 76% of patients were able to ambulate with no physical assistance. The weighted mean distance for the 6-minute walk test was 98 m. The physiologic demand of powered exoskeleton-assisted walking was 3.3 metabolic equivalents and rating of perceived exertion was 10 on the Borg 6-20 scale, comparable to self-reported exertion of an able-bodied person walking at 3 miles per hour. Improvements in spasticity and bowel movement regularity were reported in 38% and 61% of patients, respectively. No serious adverse events occurred. The incidence of fall at any time during training was 4.4%, all occurring while tethered using a first-generation exoskeleton and none resulting in injury. The incidence of bone fracture during training was 3.4%. These risks have since been mitigated with newer generation exoskeletons and refinements to patient eligibility criteria. Powered exoskeletons allow patients with SCI to safely ambulate in real-world settings at a physical activity intensity conducive to

    The process characteristics of microwave assisted hydrothermal carbonization of cellulose was investigated and a first order kinetics model based on carbon concentration was developed. Chemical properties analysis showed that comparing to conventional hydrothermal carbonization, hydrochar with comparable energy properties can be obtained with 5-10 times decrease in reaction time with assistance of microwave heating. Results from kinetics study was in great agreement with experimental analysis, that they both illustrated the predominant mechanism of the reaction depend on variations in the reaction rates of two co-existent pathways. Particularly, the pyrolysis-like intramolecular dehydration reaction was proved to be the predominant mechanism for hydrochar generation under high temperatures. Finally, the enhancement effects of microwave heating were reflected under both soluble and solid pathways in this research, suggesting microwave-assisted hydrothermal carbonization as a more attracting method for carbon-enriched hydrochar recovery.

    Highlights: Black-Right-Pointing-Pointer Chemometrics-assisted EDXRFS spectroscopy realizes direct, rapid and accurate analysis of trace bioavailable macronutrients in soils. Black-Right-Pointing-Pointer The method is minimally invasive, involves little sample preparation, short analysis times and is relatively insensitive to matrix effects. Black-Right-Pointing-Pointer This opens up the ability to rapidly characterize large number of samples/matrices with this method. - Abstract: Precision agriculture depends on the knowledge and management of soil quality (SQ), which calls for affordable, simple and rapid but accurate analysis of bioavailable soil nutrients. Conventional SQ analysis methods are tedious and expensive. We demonstrate the utility of a new chemometrics-assisted energy dispersive X-ray fluorescence and scattering (EDXRFS) spectroscopy method we have developed for direct rapid analysis of trace 'bioavailable' macronutrients (i.e. C, N, Na, Mg, P) in soils. The method exploits, in addition to X-ray fluorescence, the scatter peaks detected from soil pellets to develop a model for SQ analysis. Spectra were acquired from soil samples held in a Teflon holder analyzed using {sup 109}Cd isotope source EDXRF spectrometer for 200 s. Chemometric techniques namely principal component analysis (PCA), partial least squares (PLS) and artificial neural networks (ANNs) were utilized for pattern recognition based on fluorescence and Compton scatter peaks regions, and to develop multivariate quantitative calibration models based on Compton scatter peak respectively. SQ analyses were realized with high CMD (R{sup 2} > 0.9) and low SEP (0.01% for N and Na, 0.05% for C, 0.08% for Mg and 1.98 {mu}g g{sup -1} for P). Comparison of predicted macronutrients with reference standards using a one-way ANOVA test showed no statistical difference at 95% confidence level. To the best of the authors' knowledge, this is the first time that an XRF method has demonstrated

    A newly developed approach for trace metal elements detection for aqueous samples analysis is presented in this paper. The idea of this approach is to improve ablation efficiency by transforming the liquid sample into a dense cloud of droplets using an ultrasonic nebulizer. The resulting droplets are then subjected to analysis by laser induced breakdown spectroscopy (LIBS). A purpose-built ultrasonic nebulizer assisted LIBS (UN-LIBS) system has been applied to the analysis of aqueous samples at trace levels of concentration. Experimental investigations of solution samples were carried out with various dissolved trace metal elements (Mn, Zn, Cu, Pb, Fe, Mg and Na) using this approach. The characteristics of UN-LIBS signal of the elements were investigated regarding the lifetime and S/B ratio and the calibration curves for trace metal elements analyses. The obtained LODs are comparable or much better than the LODS of the reported signal enhancement approaches when the laser pulse energy was as low as 30 mJ. The good linearity of calibration curves and the low LODs shows the potential ability of this method for metal elements analysis application. The density of the electrons was calculated by measuring the Stark width of the line of H α . The possible mechanism of the LIBS signal enhancement of this approach was briefly discussed. (paper)

    In the past several decades, many studies have been conducted to search for non-baryonic dark matter, such as weakly interactive massive particles (WIMPs). In the search for WIMPs, charged particles incident on the detector are background particles because WIMPs are neutral. Charged particles originate from various sources, such as cosmic rays and laboratory materials surrounding the main detector. Therefore, a veto that discriminates charged particles can improve the particle detection efficiency of the entire experiment for detecting WIMPs. Here, we investigate in the thickness range of 1 mm to 5 mm, the optimal thickness of a polystyrene scintillator as a charged particle veto detector. We found that 3-mm-thick polystyrene provides the best performance to veto charged particles and the charged-particle background in the search for the WIMP signal. Furthermore, we fabricated 3-mm-thick and 5-mm-thick polystyrene charged particle veto detectors that will be used in an underground laboratory in the search for WIMP dark matter. After exposing those detectors are the actual beam line, we compared the rate of charged particles measured using those detectors and the rate simulated through a Monte Carlo simulation.

    Aim: To validate a newly developed software prototype that automatically analyses small bowel motility by comparing it directly with manual measurement. Material and methods: Forty-five patients with clinical indication for small bowel magnetic resonance imaging (MRI) were retrospectively included in this institutional review board-approved study. MRI was performed using a 1.5 T system following a standard MR-enterography protocol. Small bowel motility parameters (contractions-per-minute, luminal diameter, amplitude) were measured three times each in identical segments using the manual and the semiautomatic software-assisted method. The methods were compared for agreement, repeatability, and time needed for each measurement. All parameters were compared between the methods. Results: A total of 91 small-bowel segments were analysed. No significant intra-individual difference (p > 0.05) was found for peristaltic frequencies between the methods (mean: 4.14/min manual; 4.22/min software-assisted). Amplitudes (5.14 mm; 5.57 mm) and mean lumen diameters (17.39 mm; 14.68) differed due to systematic differences in the definition of the bowel wall. Mean duration of single measurement was significantly (p < 0.01) shorter with the software (6.25 min; 1.30 min). The scattering of repeated measurements was significantly (p < 0.05) lower using the software. Conclusion: The software-assisted method accomplished highly reliable, fast and accurate measurement of small bowel motility. Measurement precision and duration differed significantly between the two methods in favour of the software-assisted technique

    Full Text Available The lack of a comprehensive approach to the accounting reflection of repayable financial aid makes it impossible to establish an information base for the evaluation of its attraction and use. Therefore, to ensure completeness of operations related to the involvement of financial assistance is only possible through the use of scientifically based methods of accounting and scientific researches in the field of accounting should be directed at ensuring stable financial condition of the enterprise, improving management decision-making to attract and use financial aid and prevent violations of the payment discipline. Based analysis approach to mapping returnable financial assistance has shown that the accounting staff has no single method for such transactions. In order to eliminate this disadvantage we offer to display repayable financial assistance as a part of the loan capital through the use of 609 "Swivel financial assistance" account to the opening of the analytical account of 609.1 "Swivel financial assistance in the national currency", and 609.2 "Swivel financial assistance in foreign currency" and the account of 505 "Long-term financial assistance in the national currency" and 506 "Long-term financial assistance in foreign currency".

    The confrontation of gravitational waves (GWs) with their electromagnetic (EM) counterparts will be rich with information about astrophysical events. Initially, this confrontation will corroborate GW detections; afterwards, when GW detections become more recurrent, it will allow astrophysics to combine information from different channels (GW, EM and also neutrinos). A low-latency data analysis which provides the direction of an incoming GW candidate is required to confront it with fast follow-up EM observations. Until now, no low-latency data analysis has been developed for spherical detectors. One spherical detector alone is capable of determining both the GW direction and polarization. By using this capability, we have developed a low-latency data analysis pipeline for the Mario Schenberg detector. This pipeline is able to retrieve the direction of GW triggers with an average angular resolution from δs ∼ 8° at SNR ∼ 12 to δs ∼ 1° at SNR ∼ 80, in a timespan of a 4 s for 32 s of data being analyzed. We apply a veto which reduces fake events up to 90% when maintaining the GW efficiency above 90% for high SNRs. We provide here a description of the method and its efficiency: resolution on the direction, false alarm rate and computational time. (paper)

    We present a technique that enhances computer-assisted decision (CAD) systems with the ability to assess the reliability of each individual decision they make. Reliability assessment is achieved by measuring the accuracy of a CAD system with known cases similar to the one in question. The proposed technique analyzes the feature space neighborhood of the query case to dynamically select an input-dependent set of known cases relevant to the query. This set is used to assess the local (query-specific) accuracy of the CAD system. The estimated local accuracy is utilized as a reliability measure of the CAD response to the query case. The underlying hypothesis of the study is that CAD decisions with higher reliability are more accurate. The above hypothesis was tested using a mammographic database of 1337 regions of interest (ROIs) with biopsy-proven ground truth (681 with masses, 656 with normal parenchyma). Three types of decision models, (i) a back-propagation neural network (BPNN), (ii) a generalized regression neural network (GRNN), and (iii) a support vector machine (SVM), were developed to detect masses based on eight morphological features automatically extracted from each ROI. The performance of all decision models was evaluated using the Receiver Operating Characteristic (ROC) analysis. The study showed that the proposed reliability measure is a strong predictor of the CAD system's case-specific accuracy. Specifically, the ROC area index for CAD predictions with high reliability was significantly better than for those with low reliability values. This result was consistent across all decision models investigated in the study. The proposed case-specific reliability analysis technique could be used to alert the CAD user when an opinion that is unlikely to be reliable is offered. The technique can be easily deployed in the clinical environment because it is applicable with a wide range of classifiers regardless of their structure and it requires neither additional

    Background Whether or not uniportal video-assisted thoracoscopic surgery (VATS) is beneficial for spontaneous pneumothorax remains inconclusive. This meta-analysis aimed to summarize the available evidence to assess the feasibility and advantages of uniportal VATS for the treatment of spontaneous pneumothorax compared with three-port VATS. Methods Eligible publications were identified by searching the Cochrane Library, PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data databases and CQVIP. Odds ratios (OR) and standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated to compare dichotomous and continuous variables, respectively. Results This meta-analysis was based on 17 studies and included a total of 988 patients with spontaneous pneumothorax. No death was reported during the perioperative period. Compared with three-port VATS groups, there was a statistically significant difference in uniportal VATS groups regarding postoperative hospital stay (SMD= −0.58; 95% CI: −1.04 to −0.12; P=0.01), paresthesia (OR=0.13; 95% CI: 0.07 to 0.24; Pparesthesia as well as an improvement in patients’ satisfaction. This meta-analysis indicated that using uniportal VATS to treat spontaneous pneumothorax was safe and feasible, and it may be a better alternative procedure because of its advantage in reducing postoperative pain and paresthesia.

    OBJECTIVES. To understand how "cumulative inequality" (CI), expressed as individual advantage and choice, and "external social supports" contribute to the quality of social relationships and perceptions of staff assistance for older individuals in different assisted living (AL) settings. Data are from 429 cognitively intact AL residents aged 60 years and older interviewed for the Florida Study of Assisted Living. Bivariate and multivariate statistical analyses show how individual advantage and choice and external social networks influence respondents' social relationships and staff assistance in AL. Controlling for resident and facility characteristics, being able to pay privately enhances resident satisfaction with staff assistance and having control over the move to AL is positively associated with perceptions of staff relationships and assistance. Maintaining contact with pre-AL friends predicts quality of coresident relationships, as does family contact. Regular contact with family buffers some of the disadvantages associated with CI for perceptions of staff relationships but not perceptions of staff assistance. Discussion. Individual advantage and choice influence the quality of staff relationships and assistance for AL residents but matter little for coresident relationships. External social relationships buffer some of the risks associated with CI for perceptions of staff relationships but not perceived quality of staff assistance. Findings highlight outcomes associated with CI, including predictable risks that disadvantaged elders face in particular types of AL settings, differential advantages others enjoy that influence positive perceptions of staff relationships and staff assistance, and the enduring importance of supportive social relationships.

    The authors assessed a state's net costs for assisted outpatient treatment, a controversial court-ordered program of community-based mental health services designed to improve outcomes for persons with serious mental illness and a history of repeated hospitalizations attributable to nonadherence with outpatient treatment. A comprehensive cost analysis was conducted using 36 months of observational data for 634 assisted outpatient treatment participants and 255 voluntary recipients of intensive community-based treatment in New York City and in five counties elsewhere in New York State. Administrative, budgetary, and service claims data were used to calculate and summarize costs for program administration, legal and court services, mental health and other medical treatment, and criminal justice involvement. Adjusted effects of assisted outpatient treatment and voluntary intensive services on total service costs were examined using multivariate time-series regression analysis. In the New York City sample, net costs declined 43% in the first year after assisted outpatient treatment began and an additional 13% in the second year. In the five-county sample, costs declined 49% in the first year and an additional 27% in the second year. Psychotropic drug costs increased during the first year after initiation of assisted outpatient treatment, by 40% and 44% in the city and five-county samples, respectively. Regression analyses revealed significant declines in costs associated with both assisted outpatient treatment and voluntary participation in intensive services, although the cost declines associated with assisted outpatient treatment were about twice as large as those seen for voluntary services. Assisted outpatient treatment requires a substantial investment of state resources but can reduce overall service costs for persons with serious mental illness. For those who do not qualify for assisted outpatient treatment, voluntary participation in intensive community

    Skeletal muscles are composed of heterogeneous muscle fibers that have different physiological, morphological, biochemical, and histological characteristics. In this work, skeletal muscles extensor digitorum longus, soleus, and whole gastrocnemius were analyzed by matrix-assisted laser desorption/ionization mass spectrometry to characterize small molecule metabolites of oxidative and glycolytic muscle fiber types as well as to visualize biomarker localization. Multivariate data analysis such as principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were performed to extract significant features. Different metabolic fingerprints were observed from oxidative and glycolytic fibers. Higher abundances of biomolecules such as antioxidant anserine as well as acylcarnitines were observed in the glycolytic fibers, whereas taurine and some nucleotides were found to be localized in the oxidative fibers.

  11. The ethics of withdrawal: the case of follow-up from first-in-human clinical trials.

    Science.gov (United States)

    Hug, Kristina; Johansson, Mats

    2017-01-01

    This paper aims to analyze whether patients should be allowed to veto research-related use of medical data collected during routine follow-ups after their withdrawal from first-in-human clinical trials. Forms of withdrawal are identified and it is argued that the right to withdraw might be limited to some of these. The paper concludes that if veto right is denied, then: the research participant should be informed about the potential use of his/her follow-up data in case of his/her withdrawal and consent to it; follow-up should not be initiated for research purposes; compulsory use of follow-up data should imply the use of data anyway collected, requiring no additional effort from the patient; and before deciding about the veto right, investigation of concerned patients' value preferences is needed.

    2003-01-01

    This paper summarizes the U.S. Nuclear Regulatory Commission's (US NRC) technical support program activities associated with the Armenian Nuclear Power Plant (ANPP) safety upgrade. The US NRC program, integrated within the overall IAEA-led initiative for safety re-evaluation of the WWER plants, has as its main thrust the technical support to the Armenian Nuclear Regulatory Authority (ANRA) through close collaboration with the scientific staff at Brookhaven National Laboratory (BNL). Several major technical areas of support to ANRA form the basis of the NRC program. These include the seismic re-evaluation and upgrade of the ANPP, safety evaluation of critical systems, and the generation of the Safety Analysis Report (SAR). Specifically, the seismic re-evaluation of the ANPP is part of a broader activity that involves the re-assessment of the seismic hazard at the site, the identification of the Safe Shutdown Equipment at the plant and the evaluation of their seismic capacity, the detailed modeling and analysis of the critical facilities at ANPP, and the generation of the Floor Response Spectra (FRS). Based on the new spectra that incorporate all new findings (hazard, site soil, structure, etc.), the overall capacity of the main structures and the seismic capacity of the critical systems are being re-evaluated. In addition, analyses of critical safe shutdown systems and safe shutdown processes are being performed to ensure both the capabilities of the operating systems and the enhancement of safety due to system upgrades. At present, one of the principal goals of the US NRC's regulatory assistance activities with ANRA is enhancing ANRA's regulatory oversight of high-priority safety issues (both generic and plant-specific) associated with operation of the ANPP. As such, assisting ANRA in understanding and assessing plant-specific seismic and other safety issues associated with the ANPP is a high priority given the ANPP's being located in a seismically active area

    There is convincing evidence that cigarette smoking can impair female reproductive potential. This meta-analysis updates the knowledge regarding the effects of cigarette smoking on clinical outcomes of assisted reproductive technologies (ART). Twenty-six studies were included in this meta-analysis. Results were expressed as odds ratios (OR) with 95% confidence intervals (CI) and statistical heterogeneity between the studies was evaluated with Higgins (I 2 ), Breslow (τ 2 ), Birge's ratio (H 2 ) indices and Chi-square test (χ 2 ). A P-value < 0.05 was considered statistically significant. The analysis showed a significant decrease in live birth rate per cycle for smoking patients (OR 0.59, 95% CI 0.44-0.79; P = 0.0005), a significant lower clinical pregnancy rate per cycle for smoking women (OR 0.53, 95% CI 0.41-0.68; P < 0.0001), and a significant increase in terms of spontaneous miscarriage rate (OR 2.22, 95% CI 1.10-4.48; P = 0.025) for smokers. These findings demonstrate clear negative effects of cigarette smoking on the outcome of ART programs. Copyright © 2018 Elsevier Inc. All rights reserved.

  14. Physician-assisted dying: thoughts drawn from Albert Camus' writing.

    2018-03-20

    Physician-assisted dying (assisted suicide and euthanasia) is currently an intensely discussed topic in several countries. Despite differences in legislation and application, countries with end-of-life laws have similar eligibility criteria for assistance in dying: individuals must be in a hopeless situation and experience unbearable suffering. Hopelessness, as a basic aspect of the human condition, is a central topic in Albert Camus' philosophical work The Myth of Sisyphus, which addresses the question of suicide. Suffering in the face of a hopeless situation, and the way doctors approach this suffering, is the topic of his novel The Plague, which describes the story of a city confronted with a plague epidemic. In this paper, I draw philosophical and ethical conclusions about physician-assisted dying based on an analysis of central concepts in the work of Camus-specifically, those treated in The Myth of Sisyphus and The Plague. On the basis of my interpretation of Camus' work, I argue that hopelessness and unbearable suffering are useless as eligibility criteria for physician-assisted dying, given that they do not sufficiently elucidate where the line should be drawn between patients who should to be eligible for assistance and those who should not.

    For further improving the extraction efficiency of microwave extraction, a microwave-assisted contijuous extraction (MACE) device has been designed and utilized. By contrasting with the traditional methods, the characteristics and extraction efficiency of MACE has also been studied. The method was validated by the analysis of the triterpenoids in Ganoderma lucidum. The extraction conditions of MACE were: using 95% ethanol as solvent, microwave power 200 W and radiation time 14.5 min (5 cycles). The extraction results were subsequently compared with traditional heat reflux extraction ( HRE) , soxhlet extraction (SE), ultrasonic extraction ( UE) as well as the conventional microwave extraction (ME). For triterpenoids, the two methods based on the microwaves (ME and MACE) were in general capable of finishing the extraction in 10, 14.5 min, respectively, while other methods should consume 60 min and even more than 100 min. Additionally, ME can produce comparable extraction results as the classical HRE and higher extraction yield than both SE and UE, however, notably lower extraction yield than MASE. More importantly, the purity of the crud extract by MACE is far better than the other methods. MACE can effectively combine the advantages of microwave extraction and soxhlet extraction, thus enabling a more complete extraction of the analytes of TCMs in comparison with ME. And therefore makes the analytic result more accurate. It provides a novel, high efficient, rapid and reliable pretreatment technique for the analysis of TCMs, and it could potentially be extended to ingredient preparation or extracting techniques of TCMs.

    2014-03-01

    Full Text Available Recently, the algae-for-fuel concept has gained renewed interest with energy prices fluctuating widely. Due to some restrictions over the oil extraction from algae, direct transesterification may be considered as a good alternative. In this study, to improve the performance of direct transesterification, ultrasound induction was carried out. A sonicator probe was used to induce the direct transesterification of Cladophora fracta, a freshwater macro alga, which contains 14% lipid on dry biomass basis. Due to ultrasonication about 25% increased biodiesel yields were obtained and the biodiesel thus prepared was analyzed for emission characteristics. The analysis results showed that Cladophora biodiesel emits 18 mg/L of CO whereas petroleum diesel emits 50 mg/L. Similarly, the emission of NOx and particulate matter also were reduced to a considerable level. The Cladophora is a suitable source of biodiesel by ultrasound assisted direct transesterification in industrial level in the future.

    Full Text Available This study was designed to determine the ability of computer-assisted sperm morphometry analysis (CASA-Morph with fluorescence to discriminate between spermatozoa carrying different sex chromosomes from the nuclear morphometrics generated and different statistical procedures in the bovine species. The study was divided into two experiments. The first was to study the morphometric differences between X- and Y-chromosome-bearing spermatozoa (SX and SY, respectively. Spermatozoa from eight bulls were processed to assess simultaneously the sex chromosome by FISH and sperm morphometry by fluorescence-based CASA-Morph. SX cells were larger than SY cells on average (P < 0.001 although with important differences between bulls. A simultaneous evaluation of all the measured features by discriminant analysis revealed that nuclear area and average fluorescence intensity were the variables selected by stepwise discriminant function analysis as the best discriminators between SX and SY. In the second experiment, the sperm nuclear morphometric results from CASA-Morph in nonsexed (mixed SX and SY and sexed (SX semen samples from four bulls were compared. FISH allowed a successful classification of spermatozoa according to their sex chromosome content. X-sexed spermatozoa displayed a larger size and fluorescence intensity than nonsexed spermatozoa (P < 0.05. We conclude that the CASA-Morph fluorescence-based method has the potential to find differences between X- and Y-chromosome-bearing spermatozoa in bovine species although more studies are needed to increase the precision of sex determination by this technique.

    Background Powered exoskeletons are designed to safely facilitate ambulation in patients with spinal cord injury (SCI). We conducted the first meta-analysis of the available published research on the clinical effectiveness and safety of powered exoskeletons in SCI patients. Methods MEDLINE and EMBASE databases were searched for studies of powered exoskeleton-assisted walking in patients with SCI. Main outcomes were analyzed using fixed and random effects meta-analysis models. Results A total of 14 studies (eight ReWalk™, three Ekso™, two Indego®, and one unspecified exoskeleton) representing 111 patients were included in the analysis. Training programs were typically conducted three times per week, 60–120 minutes per session, for 1–24 weeks. Ten studies utilized flat indoor surfaces for training and four studies incorporated complex training, including walking outdoors, navigating obstacles, climbing and descending stairs, and performing activities of daily living. Following the exoskeleton training program, 76% of patients were able to ambulate with no physical assistance. The weighted mean distance for the 6-minute walk test was 98 m. The physiologic demand of powered exoskeleton-assisted walking was 3.3 metabolic equivalents and rating of perceived exertion was 10 on the Borg 6–20 scale, comparable to self-reported exertion of an able-bodied person walking at 3 miles per hour. Improvements in spasticity and bowel movement regularity were reported in 38% and 61% of patients, respectively. No serious adverse events occurred. The incidence of fall at any time during training was 4.4%, all occurring while tethered using a first-generation exoskeleton and none resulting in injury. The incidence of bone fracture during training was 3.4%. These risks have since been mitigated with newer generation exoskeletons and refinements to patient eligibility criteria. Conclusion Powered exoskeletons allow patients with SCI to safely ambulate in real-world settings at

    2018-04-01

    Thousands of family members worldwide are annually involved in assisted dying. Family participation in assisted dying has rarely been investigated and families' needs typically are not considered in assisted dying legislation and clinical guidelines. To explore family caregivers' reflections on experiences of assisted suicide in Switzerland. A cross-sectional qualitative interview study conducted in the Italian- and French-speaking regions of Switzerland. Interpretation and analysis were performed using qualitative content analysis. Twenty-eight close relatives and family carers of 18 patients who died by assisted suicide in Switzerland were interviewed. Family members perceived their involvement in assisted suicide as characterized by five phases; 1) contemplation, 2) gaining acceptance, 3) gaining permission, 4) organization, and 5) aftermath. Families can participate in these phases at diverse levels and with varying degrees of involvement. Important triggers for families and patients for transition between phases include patients' experiences of their life-threatening illnesses and related treatments, their increasing awareness of approaching death, and family member recognition of their loved one's unbearable suffering. Participating in assisted suicide created further demanding tasks for families in addition to their role of caregivers. Families appeared to be involved in the preparation of assisted suicide along with patients, irrespective of their personal values regarding assisted dying. Support for family members is essential if they are involved in tasks preparatory to assisted suicide. Clinical guidelines and policies concerning assisted dying should acknowledge and address family needs. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    2015-01-01

    A Rankine System assisted for solar radiation and fuel combustion which produces 57 kW electrical power are evaluated from exergoeconomic point of view. The Parabolic trough collector efficiency has been performed to investigate its effect as heat source. The exergoeconomic parameters as the relative cost difference and the exergoeconomic factor for each component are evaluated. The analysis is based on the SPECO (Specific Exergy Costing) approach. The simulation of system on March, June, September and December 21st from 7 am to 4 pm for Natal/Brazil using real data was carried out. The results reveal the daily average values of collector efficiencies, ratio of the useful solar energy, electricity produced, the specific cost per exergy unit of the produced electricity and others heat rates. The system is advantageous for higher solar radiation. The outcome of the analysis can be useful in design, optimization of operating parameters and help to take decision of investment. - Highlights: • As the solar irradiation decreases, the electricity cost per exergy unit increases. • The cost rate is high at collector field due to higher purchase cost. • The system is advantageous when the solar radiation is high. • Further aspect as environmental impact is important

    Full Text Available The peer-assisted CDN is a new content distribution paradigm supported by CDNs (e.g., Akamai, which enables clients to cache and distribute web content on behalf of a website. Peer-assisted CDNs bring significant bandwidth savings to website operators and reduce network latency for users. In this work, we show that the current designs of peer-assisted CDNs expose clients to privacy-invasive attacks, enabling one client to infer the set of browsed resources of another client. To alleviate this, we propose an anonymous peer-assisted CDN (APAC, which employs content delivery while providing initiator anonymity (i.e., hiding who sends the resource request and responder anonymity (i.e., hiding who responds to the request for peers. APAC can be a web service, compatible with current browsers and requiring no client-side changes. Our anonymity analysis shows that our APAC design can preserve a higher level of anonymity than state-of-the-art peer-assisted CDNs. In addition, our evaluation demonstrates that APAC can achieve desired performance gains.

  12. The Rise and Fall of Social Assistance Use in Canada, 1969-2012

    Directory of Open Access Journals (Sweden)

    Ronald D. Kneebone

    2014-02-01

    different movements in social assistance use, offer an interesting comparison for those interested in evaluating each province’s policies toward social assistance. In the West, social-assistance usage rates also saw a long downward trend following dramatic increases in the mid1990s. Similar to elsewhere, usage rates in Western Canada saw only minor increases in response to the 2008 recession. By 2012, social assistance usage in all Western provinces had fallen well below that in Ontario and Quebec; in Alberta, for example, the rate is only half that in central Canada. Perhaps the most dramatic changes have occurred in the Maritime Provinces where social assistance usage is only half what it was just 15 years ago and currently sits below any level observed in those provinces since 1970. Remarkably, the rate of social assistance use in Nova Scotia, New Brunswick and PEI is currently below that in Ontario. In trying to explain these trends and interprovincial differences, researchers will surely focus on the fact that the timing of the dramatic fall in social assistance usage is very close to the federal government’s decision in the mid1990s to halt shared funding of social assistance with the provinces. The end of shared financing promoted provincespecific changes in social assistance policies and it is plausible to associate the changes in these policies with the fall in social assistance usage. What exactly were those changes in each province, and a balanced assessment of their impact, requires careful analysis. We do not perform that analysis in this report; what we have done is assemble and present the data on social assistance use that is a necessary prerequisite of that analysis.

    2017-01-01

    Full Text Available The article addresses the spiritist’s conception of social assistance, starting with interviews done with 30 heads of assistencial work from spiritists’ centers in Florianópolis. The analysis was based on authors from sociology that thought about social assistance. Thus, the theme was investigated in a relational form, incorporating its formulation in a broader political context. In order to do the data analysis, the “AntConc (3.4.4” software was used for observing the most frequent words in the authors’ discourses and the statistical correlation among them as well. Some categories to analyze were pre-selected, such as: charity, assistant and assisted, among others. Hereafter, the software was used to enlarge the meaning of the discourses from other discursive elements. The aim was to establish a conceptualization of social assistance aggregating relational and contextual elements. The analyses show, among other conclusions, that the conception built from the interviewed spiritists was more referred to a religious internal universe than to a dialogue with the social context.

    The Gerda collaboration aims to determine the half life of the neutrinoless double beta decay (0νββ) of {sup 76}Ge. In Phase I, the experimental background was reduced to 10{sup -2} cts/(keV.kg.yr) in the region around Q{sub ββ}. For Phase II we want to reduce the background contribution by one order of magnitude. Cosmic muons induce part of this dangerous background and must be vetoed. The muon veto consists of a water Cherenkov detector with 66 PMTs in the water tank surrounding the Gerda cryostat which contains the germanium crystals. The muon veto operated stably for 806 days where only 2 PMTs were lost. The rate however is modulated by the Cngs neutrino beam and the atmospheric temperature effect, both will be presented in this talk.

    Gerda is an experiment to search for the neutrinoless double beta decay of {sup 76}Ge. Results of Phase I have been published in summer 2013. Currently the commissioning of Gerda Phase II is ongoing. To reach the aspired background index of ≤10{sup -3} cts/(keV.kg.yr) active background-suppression techniques will be applied, including an active liquid argon veto (LAr veto). It has been demonstrated by the LArGe test facility that the detection of argon scintillation light can be used to effectively suppress background events in the germanium, which simultaneously deposit energy in LAr. The light instrumentation consisting of photomultiplier tubes (PMT) and wavelength-shifting fibers connected to silicon multipliers (SiPM) has been installed in Gerda. In this talk the low background design of the LAr veto and its performance during the commissioning runs are reported.

    2010-01-01

    Robot-assisted pyeloplasty (RAP) is emerging as an effective tool for treatment of ureteropelvic junction obstruction (UPJO) in the pediatric population. Typically stents are utilized for RAP and removed four weeks after the procedure. We present our prospective experience with stentless RAP. Twenty children between the ages of 12 and 113 months (mean age 56 months) underwent transperitoneal RAP for UPJO utilizing the DaVinci surgical system. Outcome measures included operative time, length of hospital stay, and resolution of obstruction by ultrasonography, magnetic resonance urography (MRU), and/or diuretic radionuclide imaging (DRI). All patients successfully underwent robot-assisted laparoscopic pyeloplasty without conversion to pure laparoscopy or open procedure. Mean operative time was 124.7 min with a mean console time of 82.3 min. The mean hospital stay was 18 h. Of the 20 patients, 13/20 (65%) had resolution or improvement in the degree of hydronephrosis. The other patients had no evidence of obstruction based upon follow-up MRU or DRI. Stentless RAP is a safe and effective option for surgical treatment of UPJO. A larger prospective long-term cohort is needed to confirm the safety and efficacy of the stentless approach.

    Full Text Available A study to comprehend the requests, concerns, and questions of professionals about the assistance dynamic of a psychiatric emergency service. We conducted a case study, using the Fourth Generation assessment method, with 15 participants. We collected data using documental analysis, semi-structured interview and observation and, we used the constant comparative method for analysis. Therefore, two thematic axes arose: a Comprehending the assistance dynamic of the Psychiatric emergency service and, b The disarticulation of the psychosocial attention network as a barrier to satisfaction with the assistance in the psychiatric emergency. We considered that the assistance dynamic in the Psychiatric Emergency extrapolated the simple, unique character of stabilizing patients with acute mental disorders, once it directs the user’s flow to the adequate treatment in the psychosocial attention network.

    Full Text Available BACKGROUND: The opinion of application of indocyanine green (ICG in the macular hole surgery was contradictory. Here we conducted a meta-analysis to evaluate the effect of in internal limiting membrane (ILM peeling for macular hole surgery. METHODS AND FINDINGS: We searched electronic databases for comparative studies published before July 2012 of ILM peeling with and without ICG. Twenty-two studies including 1585 eyes were included. Visual acuity (VA improvement, including the postoperative rate of ≥20/40 VA gained (OR, 0.65; 95% CI, 0.43 to 0.97; P = 0.033 and increased LogMAR (WMD, -0.09; 95% CI, -0.16 to -0.02; P = 0.011, was less in the ICG group. The risk of visual field defects was greater in the ICG group than in the non-ICG group. There was no significant difference in the rate of anatomical outcomes between ILM peeling procedures performed with and without ICG. RPE changes and other postoperative complications were not significantly different between the ICG and non-ICG groups. An additional analysis showed that the VA improvement of the ICG group was less than the non-ICG group only within the first year of follow up. A subgroup analysis showed that the rate of VA improvement was lower in the ICG group than in other adjuncts group. A higher rate of secondary closure and less VA improvement were observed in a high proportion (>0.1% of the ICG group. A sensitivity analysis after the randomized-controlled trials were excluded from the meta-analysis demonstrated no differences compared with the overall results. CONCLUSIONS: This meta-analysis demonstrated that there is no evidence of clinical superiority in outcomes for ICG-assisted ILM peeling procedure over the non-ICG one. The toxicity of ICG should be considered when choosing the various staining methods.

  19. Early assessment of the likely cost-effectiveness of a new technology: A Markov model with probabilistic sensitivity analysis of computer-assisted total knee replacement.

    Dong, Hengjin; Buxton, Martin

    2006-01-01

    The objective of this study is to apply a Markov model to compare cost-effectiveness of total knee replacement (TKR) using computer-assisted surgery (CAS) with that of TKR using a conventional manual method in the absence of formal clinical trial evidence. A structured search was carried out to identify evidence relating to the clinical outcome, cost, and effectiveness of TKR. Nine Markov states were identified based on the progress of the disease after TKR. Effectiveness was expressed by quality-adjusted life years (QALYs). The simulation was carried out initially for 120 cycles of a month each, starting with 1,000 TKRs. A discount rate of 3.5 percent was used for both cost and effectiveness in the incremental cost-effectiveness analysis. Then, a probabilistic sensitivity analysis was carried out using a Monte Carlo approach with 10,000 iterations. Computer-assisted TKR was a long-term cost-effective technology, but the QALYs gained were small. After the first 2 years, the incremental cost per QALY of computer-assisted TKR was dominant because of cheaper and more QALYs. The incremental cost-effectiveness ratio (ICER) was sensitive to the "effect of CAS," to the CAS extra cost, and to the utility of the state "Normal health after primary TKR," but it was not sensitive to utilities of other Markov states. Both probabilistic and deterministic analyses produced similar cumulative serious or minor complication rates and complex or simple revision rates. They also produced similar ICERs. Compared with conventional TKR, computer-assisted TKR is a cost-saving technology in the long-term and may offer small additional QALYs. The "effect of CAS" is to reduce revision rates and complications through more accurate and precise alignment, and although the conclusions from the model, even when allowing for a full probabilistic analysis of uncertainty, are clear, the "effect of CAS" on the rate of revisions awaits long-term clinical evidence.

    2007-01-01

    In this study, a direct expansion solar-assisted heat pump water heater (DX-SAHPWH) with rated input power 750 W was tested and analyzed. Through experimental research in spring and thermodynamics analysis about the system performance, some suggestions for the system optimization are proposed. Then, a small-type DX-SAHPWH with rated input power 400 W was built, tested and analyzed. Through exergy analysis for each component of DX-SAHPWH (A) and (B), it can be seen that the highest exergy loss occurs in the compressor and collector/evaporator, followed by the condenser and expansion valve, respectively. Furthermore, some methods are suggested to improve the performance of each component, especially the collector/evaporator. A methodology for the design optimization of the collector/evaporator was introduced and applied. In order to maintain a proper matching between the heat pumping capacity of the compressor and the evaporative capacity of the collector/evaporator under widely varying ambient conditions, the electronic expansion valve and variable frequency compressor are suggested to be utilized for the DX-SAHPWH

    2006-04-01

    This paper reports a study describing home nurses' intention and current practices regarding introducing assistive devices, and investigating whether their practice is related to social cognitive factors (attitudes, subjective norms and self-efficacy). Home nurses not only care for patients in particular medical domains, but also educate and guide them towards more independence. Patients with age-related disabilities in mobility and self-care might benefit from the use of assistive devices. A home nurse might be the first and only person to discuss the disability and use of an assistive device. Therefore, home nurses' beliefs about the introduction of assistive devices could affect their daily practices. A cross-sectional study was conducted with a convenience sample of 64 home nurses chosen from a random sample of home nursing departments. The home nurses completed a self-administered questionnaire. The Theory of Planned Behaviour framework was used to develop the social cognitive measures regarding each of the six steps distinguished in the introduction of assistive devices. Home nurses had positive attitudes and high levels of intention, subjective norm and self-efficacy towards most steps of the decision process to introduce assistive devices. In a multiple linear regression analysis, attitude and self-efficacy predicted intention to introduce assistive devices to older clients with disabilities. Intention was correlated to home nurses' current practices. The findings suggest that conditions are present to involve home nurses more explicitly in the introduction of assistive devices to their patients. Social cognitive factors should be taken into account when developing interventions that aim to support home nurses to do this.

    In this study, we examined different computer-assisted sperm analysis (CASA) systems (CRISMAS, Hobson Sperm Tracker, and Image J CASA) on the exact same video recordings to evaluate the differences in sperm motility parameters related to the specific CASA used. To cover a wide range of sperm motility parameters, we chose 12-second video recordings at 25 and 50 Hz frame rates after sperm motility activation using three taxonomically distinct fish species (sterlet: Acipenser ruthenus L.; common carp: Cyprinus carpio L.; and rainbow trout: Oncorhynchus mykiss Walbaum) that are characterized by essential differences in sperm behavior during motility. Systematically higher values of velocity and beat cross frequency (BCF) were observed in video recordings obtained at 50 Hz frame frequency compared with 25 Hz for all three systems. Motility parameters were affected by the CASA and species used for analyses. Image J and CRISMAS calculated higher curvilinear velocity (VCL) values for rainbow trout and common carp at 25 Hz frequency compared with the Hobson Sperm Tracker, whereas at 50 Hz, a significant difference was observed only for rainbow trout sperm recordings. No significant difference was observed between the CASA systems for sterlet sperm motility at 25 and 50 Hz. Additional analysis of 1-second segments taken at three time points (1, 6, and 12 seconds of the recording) revealed a dramatic decrease in common carp and rainbow trout sperm speed. The motility parameters of sterlet spermatozoa did not change significantly during the 12-second motility period and should be considered as a suitable model for longer motility analyses. Our results indicated that the CASA used can affect motility results even when the same motility recordings are used. These results could be critically altered by the recording quality, time of analysis, and frame rate of camera, and could result in erroneous conclusions. Copyright © 2013 Elsevier Inc.

  5. Thirty-five years of assisted reproductive technologies in Israel

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Israel is known as a pronatalist country. Whether due to the Biblical commandment to ‘be fruitful and multiply’ or the traumas of the Holocaust and perennial wars, reproduction is a central life goal for most Israelis. Israeli women bear substantially more children than their counterparts in industrialized countries and view child-rearing as a key life accomplishment. These personal world-view and real-life individual quests take place in a context of equally pronatalist state policies and religious openness to assisted reproductive technologies. In this paper, I outline 35 years of assisted reproductive technologies in Israel by tracing a principal axis in the development of three major technologies of assisted reproduction: the proliferation of IVF-ICSI; the globalization of gamete donation; and the privatization of surrogacy. The paper is based on a policy analysis as well as various studies of assisted reproductive technologies, conducted in Israel over this period.

    The National Early Care and Education Learning Collaboratives Project (ECELC) aims to improve best practices in early care and education (ECE) programs in topic areas of the Nutrition and Physical Activity Self-Assessment in Child Care (NAP SACC). Technical assistance is a component of the ECELC, yet its effect on outcomes is unclear. Beyond dose and duration of technical assistance, limited research exists on characteristics of technical assistance that contribute to outcomes. The objective of this study was to identify and describe technical assistance characteristics and explore associations with NAP SACC outcomes. We collected data from 10 collaboratives comprising 84 ECE programs in 2 states in 2015-2016. The objective of technical assistance was to support programs in improving best practices. Technical assistance was provided to programs via on-site, telephone, or email and was tailored to program needs. We used a mixed-methods design to examine associations between technical assistance and NAP SACC outcomes. We used multiple regression analysis to assess quantitative data and qualitative comparative analysis to determine necessary and sufficient technical assistance conditions supporting NAP SACC outcomes. We also conducted a document review to describe technical assistance that referred conditions identified by the qualitative comparative analysis. Regression analyses detected an inverse relationship between changes in NAP SACC scores and hours of technical assistance. No clear pattern emerged in the qualitative comparative analysis, leaving no necessary and sufficient conditions. However, the qualitative comparative analysis identified feedback as a potentially important component of technical assistance, whereas resource sharing and frequent email were characteristics that seemed to reduce the likelihood of improved outcomes. Email and resource sharing were considered primarily general information rather than tailored technical assistance. Technical

    In this report, laser radiation (808nm) for the first time was employed to enhance the efficiency of proteolysis through immobilized enzyme reactor (IMER). IMER based monolithic support was prepared in the fused-silica capillary via a simple two-step procedure including acryloylation on trypsin surface and in situ aqueous polymerization/immobilization. The feasibility and high efficiency of the laser-assisted IMER were demonstrated by the digestion of bovine serum albumin (BSA), cytochrome c (Cyt-c) and β-casein. The digestion process was achieved in 60s. The peptides were identified by MALDI-TOF-MS, yielding the sequence coverage of 33% for BSA, 73% for Cyt-c and 22% for β-casein. The comparisons between the in-solution digestion and on IMER reaction with/without laser assistance were made. To further confirm its efficiency in proteome analysis, the laser-assisted IMER was also applied to the analysis of one fraction of human serum sample through two-dimensional (2-D) separation of strong anion exchange/reversed-phase liquid chromatography (SAX/RPLC). After a database search, 49 unique peptides corresponding to 5 proteins were identified. The results showed that the laser-assisted IMER provides a promising platform for the high-throughput protein identification. Copyright © 2011 Elsevier B.V. All rights reserved.

    2015-01-01

    Highlights: • The work focuses on solar assisted ground source heat pump in cold climates. • Multi-year simulations of SAGSHP, are carried out in six cold locations. • GSHP and SAGSHP are compared. • The effect of total borehole length on the heat pump energy efficiency is studied. • A dedicated control strategy is used to manage both solar and ground loops. - Abstract: Exploiting renewable energy sources for air-conditioning has been extensively investigated over recent years, and many countries have been working to promote the use of renewable energy to decrease energy consumption and CO_2 emissions. Electrical heat pumps currently represent the most promising technology to reduce fossil fuel usage. While ground source heat pumps, which use free heat sources, have been taking significant steps forward and despite the fact that their energy performance is better than that of air source heat pumps, their development has been limited by their high initial investment cost. An alternative solution is one that uses solar thermal collectors coupled with a ground source heat pump in a so-called solar assisted ground source heat pump. A ground source heat pump system, used to heat environments located in a cold climate, was investigated in this study. The solar assisted ground source heat pump extracted heat from the ground by means of borehole heat exchangers and it injected excess solar thermal energy into the ground. Building load profiles are usually heating dominated in cold climates, but when common ground source heat pump systems are used only for heating, their performance decreases due to an unbalanced ground load. Solar thermal collectors can help to ensure that systems installed in cold zones perform more efficiently. Computer simulations using a Transient System Simulation (TRNSYS) tool were carried out in six cold locations in order to investigate solar assisted ground source heat pumps. The effect of the borehole length on the energy efficiency of

    The influence of sonoluminescence transesterification on biodiesel physicochemical properties was investigated and the results were compared to those of traditional mechanical stirring. This study was conducted to identify the mechanistic features of ultrasonication by coupling statistical analysis of the experiments into the simulation of cavitation bubble. Different combinations of operational variables were employed for alkali-catalysis transesterification of palm oil. The experimental results showed that transesterification with ultrasound irradiation could change the biodiesel density by about 0.3kg/m(3); the viscosity by 0.12mm(2)/s; the pour point by about 1-2°C and the flash point by 5°C compared to the traditional method. Furthermore, 93.84% of yield with alcohol to oil molar ratio of 6:1 could be achieved through ultrasound assisted transesterification within only 20min. However, only 89.09% of reaction yield was obtained by traditional macro mixing/heating under the same condition. Based on the simulated oscillation velocity value, the cavitation phenomenon significantly contributed to generation of fine micro emulsion and was able to overcome mass transfer restriction. It was found that the sonoluminescence bubbles reached the temperature of 758-713K, pressure of 235.5-159.55bar, oscillation velocity of 3.5-6.5cm/s, and equilibrium radius of 17.9-13.7 times greater than its initial size under the ambient temperature of 50-64°C at the moment of collapse. This showed that the sonoluminescence bubbles were in the condition in which the decomposition phenomena were activated and the reaction rate was accelerated together with a change in the biodiesel properties.

  12. Assisted suicide and euthanasia.

    Science.gov (United States)

    van der Heide, Agnes

    2013-01-01

    Several countries have adopted laws that regulate physician assistance in dying. Such assistance may consist of providing a patient with a prescription of lethal medication that is self-administered by the patient, which is usually referred to as (physician) assistance in suicide, or of administering lethal medication to a patient, which is referred to as euthanasia. The main aim of regulating physician assistance in dying is to bring these practices into the open and to provide physicians with legal certainty. A key condition in all jurisdictions that have regulated either assistance in suicide or euthanasia is that physicians are only allowed to engage in these acts upon the explicit and voluntary request of the patient. All systems that allow physician assistance in dying have also in some way included the notion that physician assistance in dying is only accepted when it is the only means to address severe suffering from an incurable medical condition. Arguments against the legal regulation of physician assistance in dying include principled arguments, such as the wrongness of hastening death, and arguments that emphasize the negative consequences of allowing physician assistance in dying, such as a devaluation of the lives of older people, or people with chronic disease or disabilities. Opinion polls show that some form of accepting and regulating euthanasia and physician assistance in suicide is increasingly supported by the general population in most western countries. Studies in countries where physician assistance in dying is regulated suggest that practices have remained rather stable in most jurisdictions and that physicians adhere to the legal criteria in the vast majority of cases. © 2013 Elsevier B.V.

    A vibration-assisted polishing device (VAPD) composed of leaf-spring and right-circular flexure hinges is proposed with the aim of realizing vibration-assisted machining along elliptical trajectories. To design the structure, energy methods and the finite-element method are used to calculate the performance of the proposed VAPD. An improved bacterial foraging optimization algorithm is used to optimize the structural parameters. In addition, the performance of the VAPD is tested experimentally. The experimental results indicate that the maximum strokes of the two directional mechanisms operating along the Z1 and Z2 directions are 29.5 μm and 29.3 μm, respectively, and the maximum motion resolutions are 10.05 nm and 10.01 nm, respectively. The maximum working bandwidth is 1,879 Hz, and the device has a good step response.

    Employee assistance programs have grown at a dramatic rate, yet the effectiveness of these programs has been called into question. The purpose of this paper was to assess the effectiveness of employee assistance programs (EAPs) by reviewing recently published EAP evaluations. All studies evaluating EAPs published since 1975 from peer-reviewed journals in the English language were included in this analysis. Each of the articles was assessed in the following areas: (a) program description (subjects, setting, type of intervention, format), (b) evaluation design (research design, variables measured, operational methods), and (c) program outcomes. Results indicate numerous methodological and conceptual weaknesses and issues. These weaknesses included lack of controlled research designs and short time lags between pre- and post-test measures. Other problems identified are missing information regarding subjects, type of intervention, how variables are measured (operational methods), and reliability and validity of evaluation instruments. Due to the aforementioned weaknesses, positive outcomes could not be supported. Recommendations are made for future EAP evaluations.

  16. Computer-assisted 3D kinematic analysis of all leg joints in walking insects.

    Directory of Open Access Journals (Sweden)

    John A Bender

    Full Text Available High-speed video can provide fine-scaled analysis of animal behavior. However, extracting behavioral data from video sequences is a time-consuming, tedious, subjective task. These issues are exacerbated where accurate behavioral descriptions require analysis of multiple points in three dimensions. We describe a new computer program written to assist a user in simultaneously extracting three-dimensional kinematics of multiple points on each of an insect's six legs. Digital video of a walking cockroach was collected in grayscale at 500 fps from two synchronized, calibrated cameras. We improved the legs' visibility by painting white dots on the joints, similar to techniques used for digitizing human motion. Compared to manual digitization of 26 points on the legs over a single, 8-second bout of walking (or 106,496 individual 3D points, our software achieved approximately 90% of the accuracy with 10% of the labor. Our experimental design reduced the complexity of the tracking problem by tethering the insect and allowing it to walk in place on a lightly oiled glass surface, but in principle, the algorithms implemented are extensible to free walking. Our software is free and open-source, written in the free language Python and including a graphical user interface for configuration and control. We encourage collaborative enhancements to make this tool both better and widely utilized.

  17. The Distinction Between Curative and Assistive Technology.

    Stramondo, Joseph A

    2018-05-01

    Disability activists have sometimes claimed their disability has actually increased their well-being. Some even say they would reject a cure to keep these gains. Yet, these same activists often simultaneously propose improvements to the quality and accessibility of assistive technology. However, for any argument favoring assistive over curative technology (or vice versa) to work, there must be a coherent distinction between the two. This line is already vague and will become even less clear with the emergence of novel technologies. This paper asks and tries to answer the question: what is it about the paradigmatic examples of curative and assistive technologies that make them paradigmatic and how can these defining features help us clarify the hard cases? This analysis will begin with an argument that, while the common views of this distinction adequately explain the paradigmatic cases, they fail to accurately pick out the relevant features of those technologies that make them paradigmatic and to provide adequate guidance for parsing the hard cases. Instead, it will be claimed that these categories of curative or assistive technologies are defined by the role the technologies play in establishing a person's relational narrative identity as a member of one of two social groups: disabled people or non-disabled people.

    Ambient assisted living (AAL) may support ageing in place but is primarily driven by technology. The aim of this work is, to identifying reasons to move into assisted living institutions, their range of service and possible substitutability. We did semi-structured interviews with five experts from assisted living institutions and used results to design and implement assistive technologies in an AAL environment using BASIS, a cross domain bus system for smart buildings. Reasons for moving to assisted living institutions are expected benefits for chronic health problems, safety, social isolation and carefree living. We implemented six application systems for inactivity monitoring, stove shutdown, air quality monitoring, medication and appointment reminders, detection of unwanted situations before leaving and optical ringing of the doorbell. Substitution of selected assisted living services is feasible and has potential to delay necessity to move into assisted living institution if complement social services are installed.

    Changing the speed of left ventricular assist devices (LVADs) cyclically may be useful to restore aortic pulsatility; however, the effects of this pulsation on right ventricular (RV) function are unknown. This study investigates the effects of direct ventricular interaction by quantifying the amount of wave energy created by RV contraction when axial and centrifugal LVADs are used to assist the left ventricle. In 4 anesthetized pigs, pressure and flow were measured in the main pulmonary artery and wave intensity analysis was used to identify and quantify the energy of waves created by the RV. The axial pump depressed the intensity of waves created by RV contraction compared with the centrifugal pump. In both pump designs, there were only minor and variable differences between the continuous and pulsed operation on RV function. The axial pump causes the RV to contract with less energy compared with a centrifugal design. Diminishing the ability of the RV to produce less energy translates to less pressure and flow produced, which may lead to LVAD-induced RV failure. The effects of pulsed LVAD operation on the RV appear to be minimal during acute observation of healthy hearts. Further study is necessary to uncover the effects of other modes of speed modulation with healthy and unhealthy hearts to determine if pulsed operation will benefit patients by reducing LVAD complications.

    Full Text Available To develop a detailed reaction mechanism for plasma-assisted methane steam reforming, a comprehensive numerical and experimental study of effect laws on methane conversion and products yield is performed at different steam to methane molar ratio (S/C, residence time s, and reaction temperatures. A CHEMKIN-PRO software with sensitivity analysis module and path flux analysis module was used for simulations. A set of comparisons show that the developed reaction mechanism can accurately predict methane conversion and the trend of products yield in different operating conditions. Using the developed reaction mechanism in plasma-assisted kinetic model, the reaction path flux analysis was carried out. The result shows that CH3 recombination is the limiting reaction for CO production and O is the critical species for CO production. Adding 40 wt.% Ni/SiO2 in discharge region has significantly promoted the yield of H2, CO, or CO2 in dielectric packed bed (DPB reactor. Plasma catalytic hybrid reforming experiment verifies the reaction path flux analysis tentatively.

  2. Direct expansion solar assisted heat pumps – A clean steady state approach for overall performance analysis

    2014-01-01

    Traditional thermal solar panel technologies have limited efficiency and the required economic investments make them noncompetitive in the space heating market. The greatest limit to the diffusion of thermal solar systems is the characteristic temperatures they can reach: the strong connection between the user temperature and the collector temperature makes it possible to achieve high thermal (collector) efficiency only at low, often useless, user temperatures. By using solar collectors as thermal exchange units (evaporators) in a heat pump system (direct expansion solar assisted heat pump, DX-SAHP), the overall efficiency greatly increases with a significative cut of the associated investment in terms of pay-back time. In this study, an approach is proposed to the steady state analysis of DX-SAHP, which is based on the simplified inverse Carnot cycle and on the second law efficiency concept. This method, without the need of calculating the refrigerant fluid properties and the detailed processes occurring in the refrigeration device, allows us to link the main features of the plant to its relevant interactions with the surroundings. The very nature of the proposed method makes the relationship explicit and meaningful among all the involved variables. The paper, after the description of the method, presents an explanatory application of this technique by reviewing various aspects of the performance of a typical DX-SAHP in which the savings on primary energy consumption is regarded as the main feature of the plant and highlighted in a monthly averaged analysis. Results agree to those coming from a common standard steady state thermodynamic analysis. The application to a typical DX-SAHP system demonstrates that a mean saved primary energy of about 50% with respect to standard gas burner can be achieved for the same user needs. Such a result is almost independent from the type of flat plate solar panel used (double or single glazed, or even bare panels) as a result of

    Full Text Available Introduction: Current medical technologies in care in birth increased maternal and fetal benefits persist, despite numerous unnecessary procedures. The purpose of the normal childbirth care is to have healthy women and newborns, using a minimum of safe interventions. Objective: To analyze the assistance to normal delivery in secondary care maternity. Methodology: A total of 100 primiparous mothers who had vaginal delivery were included, in which care practices used were categorized: 1 according to the WHO classification for assistance to normal childbirth: effective, harmful, used with caution and used inappropriately; 2 associating calculations with the Bologna Index parameters: presence of a birth partner, partograph, no stimulation of labor, delivery in non-supine position, and mother-newborn skin-to-skin contact. Results: Birth partners (85%, correctly filled partographs (62%, mother-newborn skin-to-skin contact (36%, use of oxytocin (87%, use of parenteral nutrition during labor (86% and at delivery (74%, episiotomy (94% and uterine fundal pressure in the expulsion stage (58%. The overall average value of the Bologna Index of the mothers analyzed was 1.95. Conclusions: Some effective procedures recommended by WHO (presence of a birth partner, some effective and mandatory practices were not complied with (partograph completely filled, potentially harmful or ineffective procedures were used (oxytocin in labor/post-partum, as well as inadequate procedures (uterine fundal pressure during the expulsion stage, use of forceps and episiotomy.

  4. Risk of chromosomal abnormalities in early spontaneous abortion after assisted reproductive technology: a meta-analysis.

    Directory of Open Access Journals (Sweden)

    Jun-Zhen Qin

    Full Text Available BACKGROUND: Studies on the risk of chromosomal abnormalities in early spontaneous abortion after assisted reproductive technology (ART are relatively controversial and insufficient. Thus, to obtain a more precise evaluation of the risk of embryonic chromosomal abnormalities in first-trimester miscarriage after ART, we performed a meta-analysis of all available case-control studies relating to the cytogenetic analysis of chromosomal abnormalities in first-trimester miscarriage after ART. METHODS: Literature search in the electronic databases MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL based on the established strategy. Meta-regression, subgroup analysis, and Galbraith plots were conducted to explore the sources of heterogeneity. RESULTS: A total of 15 studies with 1,896 cases and 1,186 controls relevant to the risk of chromosomal abnormalities in first- trimester miscarriage after ART, and 8 studies with 601 cases and 602 controls evaluating frequency of chromosome anomaly for maternal age≥35 versus <35 were eligible for the meta-analysis. No statistical difference was found in risk of chromosomally abnormal miscarriage compared to natural conception and the different types of ART utilized, whereas the risk of fetal aneuploidy significantly increased with maternal age≥35 (OR 2.88, 95% CI: 1.74-4.77. CONCLUSIONS: ART treatment does not present an increased risk for chromosomal abnormalities occurring in a first trimester miscarriage, but incidence of fetal aneuploidy could increase significantly with advancing maternal age.

    To improve lunar landing performances in terms of mission costs, trajectory determination and visibility the use of a single probe located over an assistance orbit around the Moon has been taken into consideration. To this end, the properties of two quasi-circular orbits characterised by a stable behaviour of semi-major axis, eccentricity and inclination have been investigated. The analysis has demonstrated the possibility of using an assistance probe, located over one of these orbits, as a relay satellite between lander and Earth, even in the case of landings on the far side of the Moon. A comparison about the accuracy in retrieving the lander's state with respect to the use of a probe located in the Lagrangian point L2 of the Earth-Moon system has also been carried out.

    Advanced heart failure treated with a left ventricular assist device is associated with a higher risk of right heart failure. Many advanced heart failures patients are treated with an ICD, a relative contraindication to MRI, prior to assist device placement. Given this limitation, left and right ventricular function for patients with an ICD is calculated using radionuclide angiography utilizing planar multigated acquisition (MUGA) and first pass radionuclide angiography (FPRNA), respectively. Given the availability of MRI protocols that can accommodate patients with ICDs, we have correlated the findings of ventricular functional analysis using radionuclide angiography to cardiac MRI, the reference standard for ventricle function calculation, to directly correlate calculated ejection fractions between these modalities, and to also assess agreement between available echocardiographic and hemodynamic parameters of right ventricular function. A retrospective review from January 2012 through May 2014 was performed to identify advanced heart failure patients who underwent both cardiac MRI and radionuclide angiography for ventricular functional analysis. Nine heart failure patients (8 men, 1 woman; mean age of 57.0 years) were identified. The average time between the cardiac MRI and radionuclide angiography exams was 38.9 days (range: 1 - 119 days). All patients undergoing cardiac MRI were scanned using an institutionally approved protocol for ICD with no device-related complications identified. A retrospective chart review of each patient for cardiomyopathy diagnosis, clinical follow-up, and echocardiogram and right heart catheterization performed during evaluation was also performed. The 9 patients demonstrated a mean left ventricular ejection fraction (LVEF) using cardiac MRI of 20.7% (12 - 40%). Mean LVEF using MUGA was 22.6% (12 - 49%). The mean right ventricular ejection fraction (RVEF) utilizing cardiac MRI was 28.3% (16 - 43%), and the mean RVEF calculated by

We conducted the first meta-analysis of the available published research on the clinical effectiveness and safety of powered exoskeletons in SCI patients. Methods: MEDLINE and EMBASE databases were searched for studies of powered exoskeleton-assisted walking in patients with SCI. Main outcomes were analyzed using fixed and random effects meta-analysis models. Results: A total of 14 studies (eight ReWalk™, three Ekso™, two Indego®, and one unspecified exoskeleton representing 111 patients were included in the analysis. Training programs were typically conducted three times per week, 60–120 minutes per session, for 1–24 weeks. Ten studies utilized flat indoor surfaces for training and four studies incorporated complex training, including walking outdoors, navigating obstacles, climbing and descending stairs, and performing activities of daily living. Following the exoskeleton training program, 76% of patients were able to ambulate with no physical assistance. The weighted mean distance for the 6-minute walk test was 98 m. The physiologic demand of powered exoskeleton-assisted walking was 3.3 metabolic equivalents and rating of perceived exertion was 10 on the Borg 6–20 scale, comparable to self-reported exertion of an able-bodied person walking at 3 miles per hour. Improvements in spasticity and bowel movement regularity were reported in 38% and 61% of patients, respectively. No serious adverse events occurred. The incidence of fall at any time during training was 4.4%, all occurring while tethered using a first-generation exoskeleton and none resulting in injury. The incidence of bone fracture during training was 3

    This study explored the experience of children with physical disabilities using assistive technology for participation with schoolwork to gain a greater understanding of their perspectives and subjective experiences. A qualitative study involving thematic analysis of in-depth interviews of the child with a parent or significant adult. Purposeful sampling from a larger study recruited five children aged between 10 and 14 years, with differing physical disabilities who attended mainstream schools. All children used computer-based assistive technology. All of the children recognised that assistive technology enabled them to participate and reduced the impact of their physical disability, allowing independent participation, and facilitated higher learning outcomes. Issues related to ease of use, social implications and assistive technology systems are discussed.

    Da Vinci robot-assisted thymectomy has been used in the past several years in China, however, practical experience in performing this approach in China remains limited. Thus, the study aimed to evaluate the experience of da Vinci robot-assisted thymectomy in China. From June 2010 to December 2012, 55 patients with diseases of the thymus underwent thymectomy using the da Vinci surgical HD robotic system. The clinical data of the da Vinci robot-assisted thymectomies were compared with the data of video-assisted thoracoscopic thymectomies in the same period. All da Vinci robot operations were successful. This is a retrospective analysis which demonstrated that compared with video-assisted thoracoscopic thymectomy in the same period, the clinical outcomes of da Vinci robot-assisted thymectomy were not significantly different. The da Vinci robot-assisted thymectomy is a safe, minimally invasive, and convenient operation, and shows promise for general thoracic surgery in China. Copyright © 2014 John Wiley & Sons, Ltd.

    The present work deals with synthesis of Fe (III) doped TiO 2 catalyst using the ultrasound assisted approach and conventional sol-gel approach with an objective of establishing the process intensification benefits. Effect of operating parameters such as Fe doping, type of solvent, solvent to precursor ratio and initial temperature has been investigated to get the best catalyst with minimum particle size. Comparison of the catalysts obtained using the conventional and ultrasound assisted approach under the optimized conditions has been performed using the characterization techniques like DLS, XRD, BET, SEM, EDS, TEM, FTIR and UV-Vis band gap analysis. It was established that catalyst synthesized by ultrasound assisted approach under optimized conditions of 0.4mol% doping, irradiation time of 60min, propan-2-ol as the solvent with the solvent to precursor ratio as 10 and initial temperature of 30°C was the best one with minimum particle size as 99nm and surface area as 49.41m 2 /g. SEM analysis, XRD analysis as well as the TEM analysis also confirmed the superiority of the catalyst obtained using ultrasound assisted approach as compared to the conventional approach. EDS analysis also confirmed the presence of 4.05mol% of Fe element in the sample of 0.4mol% iron doped TiO 2 . UV-Vis band gap results showed the reduction in band gap from 3.2eV to 2.9eV. Photocatalytic experiments performed to check the activity also confirmed that ultrasonically synthesized Fe doped TiO 2 catalyst resulted in a higher degradation of Acid Blue 80 as 38% while the conventionally synthesized catalyst resulted in a degradation of 31.1%. Overall, the work has clearly established importance of ultrasound in giving better catalyst characteristics as well as activity for degradation of the Acid Blue 80 dye.

  12. Assisted suicide through the prism of the right to life.

    Mendelson, Danuta; Bagaric, Mirko

    2013-01-01

    Part of the reason for the ongoing confusion regarding the status of assisted suicide is the cluttered moral and legal matrix that is normally invoked to evaluate the practice. It results in a calculus that is impossible to coherently unravel, allowing commentators to tenably assert any position. The authors attempt to inject clarity into the debate by focusing on the issue through the lens of the most important interest at stake: the right to life. It is arguable that while there are well-established exceptions to the right to life, they only apply where the right to life is itself at stake (such as self-defence). There is no sound argument for suggesting that the circumstances underpinning suicide constitute another exception to the right to life. Thus, suicide and assisted suicide are unjustifiable. An analysis of the empirical data in jurisdictions where assisted suicide has been legalised suggests that legalisation leads to an increase in assisted suicides. The adverse indirect consequences of the often ostensibly compassionate act of assisted suicide outweigh any supposed benefits from the practice. It follows that assisted suicide should lead to criminal sanctions. At the same time, it is important to acknowledge that, paradoxically, the right to life arguments against assisted suicide mandate greater community measures to eliminate or reduce the causes of suicide.

    OBJECTIVE The objective of this study was to investigate the association between food assistance program participation and overweight/obesity according to poverty level. METHODS A cross-sectional analysis of data from 46,217 non-pregnant and non-lactating women in Lima, Peru was conducted; these data were obtained from nationally representative surveys from the years 2003, 2004, 2006, and 2008-2010. The dependent variable was overweight/obesity, and the independent variable was food assistance program participation. Poisson regression was used to stratify the data by family socioeconomic level, area of residence (Lima versus the rest of the country; urban versus rural), and survey year (2003-2006 versus 2008-2010). The models were adjusted for age, education level, urbanization, and survey year. RESULTS Food assistance program participation was associated with an increased risk of overweight/obesity in women living in homes without poverty indicators [prevalence ratio (PR) = 1.29; 95% confidence interval (CI) 1.06;1.57]. When stratified by area of residence, similar associations were observed for women living in Lima and urban areas; no associations were found between food assistance program participation and overweight/obesity among women living outside of Lima or in rural areas, regardless of the poverty status. CONCLUSIONS Food assistance program participation was associated with overweight/obesity in non-poor women. Additional studies are required in countries facing both aspects of malnutrition.

    2004-01-01

    Purpose: A software assistant for automatic evaluation of CT-angiograms (CTA) was developed. It should enable the visualization of the vessel lumen and the quantitative evaluation of a stenosis. CTA examinations of patients with suspected carotid artery stenoses were used for the evaluation of the software assistant. Materials and Methods: Twelve Patients with suspected highgrade stenosis of the carotid arteries underwent a CTA examination using a multislice CT scanner. The data were analyzed and evaluated using the new software assistant. The results were compared with the data of digital subtraction angiography (DSA) of these patients. Results: The time of digital postprocessing with the new software-assistant took about six minutes on average. Contour extraction of the vessel, MIP and curved MPR (c-MPR) and orthogonal cross-sectional images of the vessels were calculated, followed by an automatic quantification of stenosis by the use of the C-MPR. A good correlation was found between CTA and DSA data regarding the stenosis grade (r=0.82). Furthermore, some information could be provided about the plaque morphology. Conclusion: The software-assisted detection and analysis of carotid artery stenosis with the new developed program is possible within a justifiable time. DSA- and CTA-data did not show a significant difference in stenosis grading. Further development of software tools could lead to a better characterization of plaque morphology. (orig.) [de

    ECG is an essential diagnostic tool in patients with acute coronary syndrome. We aimed to determine how many patients presenting with atypical symptoms for an acute myocardial infarction show ST-segment elevations on prehospital ECG. We also aimed to study the feasibility of telemetric-assisted prehospital ECG analysis. Between April 2010 and February 2011, consecutive emergency patients presenting with atypical symptoms such as nausea, vomiting, atypical chest pain, palpitations, hypertension, syncope, or dizziness were included in the study. After basic measures were completed, a 12-lead ECG was written and telemetrically transmitted to the cardiac center, where it was analyzed by attending physicians. Any identification of an ST-elevation myocardial infarction resulted in patient admission at the closest coronary angiography facility. A total of 313 emergency patients presented with the following symptoms: dyspnea, nausea, vomiting, dizziness/collapse, or acute hypertension. Thirty-four (11%) patients of this cohort were found to show ST-segment elevations on the 12-lead ECG. These patients were directly admitted to the closest coronary catheterization facility rather than the closest hospital. The time required for transmission and analysis of the ECG was 3.6±1.2 min. Telemetry-assisted 12-lead ECG analysis in a prehospital setting may lead to earlier detection of ST-elevation myocardial infarction in patients with atypical symptoms. Thus, a 12-lead ECG should be considered in all prehospital patients both with typical and atypical symptoms.

  20. Why not Commercial Assistance for Suicide? On the Question of Argumentative Coherence of Endorsing Assisted Suicide.

    Most people who endorse physician-assisted suicide are against commercially assisted suicide - a suicide assisted by professional non-medical providers against payment. The article questions if this position - endorsement of physician-assisted suicide on the one hand and rejection of commercially assisted suicide on the other hand - is a coherent ethical position. To this end the article first discusses some obvious advantages of commercially assisted suicide and then scrutinizes six types of argument about whether they can justify the rejection of commercially assisted suicide while simultaneously endorsing physician-assisted suicide. The conclusion is that they cannot provide this justification and that the mentioned position is not coherent. People who endorse physician-assisted suicide have to endorse commercially assisted suicide as well, or they have to revise their endorsement of physician-assisted suicide. © 2014 John Wiley & Sons Ltd.

    2014-05-01

    The long-term treatment results of surgically-assisted facemask therapy were assessed by a comparison of the immediate protraction effects with those seen at five years review. Nine patients treated with a corticotomy-assisted maxillary protraction protocol were recalled five years following protraction. Cephalometric films taken before treatment (T0), immediately after maxillary protraction (T1) and five years after treatment (T2) were compared. The short-term results of surgically-assisted facemask therapy showed significant skeletal and soft tissue changes. After five years, the profile and dental relationships were well maintained and a cephalometric analysis revealed a stable vertical increase but only partially maintained soft tissue changes with loss of sagittal advancement. There was significant upper incisor proclination providing dental camouflage. Patients who are treated with corticotomy-assisted maxillary advancement should be very carefully selected. Assessment criteria include a low mandibular plane angle Class III patients who have severe maxillary retrognathism unable to be treated by conventional orthopaedic correction alone; patients who have almost completed growth and missed the chance of earlier orthopaedic correction, as well as patients who are not willing to accept bimaxillary orthognathic surgery, may be successfully treated.

    Nanoparticle assisted laser desorption/ionization mass spectrometry (NPs-ALDI-MS) shows remarkable characteristics and has a promising future in terms of real sample analysis. The incorporation of NPs can advance several methods including surface assisted LDI-MS, and surface enhanced LDI-MS. These methods have advanced the detection of many thermally labile and nonvolatile biomolecules. Nanoparticles circumvent the drawbacks of conventional organic matrices for the analysis of small molecules. In most cases, NPs offer a clear background without interfering peaks, absence of fragmentation of thermally labile molecules, and allow the ionization of species with weak noncovalent interactions. Furthermore, an enhancement in sensitivity and selectivity can be achieved. NPs enable straightforward analysis of target species in a complex sample. This review (with 239 refs.) covers the progress made in laser-based mass spectrometry in combination with the use of metallic NPs (such as AuNPs, AgNPs, PtNPs, and PdNPs), NPs consisting of oxides and chalcogenides, silicon-based NPs, carbon-based nanomaterials, quantum dots, and metal-organic frameworks. Graphical abstract An overview is given on nanomaterials for use in surface-assisted laser desorption/ionization mass spectrometry of small molecules.

    Computer-assisted methods of CT brain scan analysis offer considerable advantages over visual inspection, particularly in research; and several semi-automated methods are currently available. A new computer-assisted program is presented which provides fully automated processing of CT brain scans, depending on ''anatomical knowledge'' of where cerebrospinal fluid (CSF)-containing spaces are likely to lie. After identifying these regions of interest quantitative estimates are then provided of CSF content in each slice in cisterns, ventricles, Sylvian fissure and interhemispheric fissure. Separate measures are also provided of mean brain density in each slice. These estimates can be summated to provide total ventricular and total brain volumes. The program shows a high correlation with measures derived from mechanical planimetry and visual grading procedures, also when tested against a phantom brain of known ventricular volume. The advantages and limitations of the present program are discussed.

    Breast cancers that overexpress the human epidermal growth factor receptor 2 (HER2) are eligible for effective biologically targeted therapies, such as trastuzumab. However, accurately determining HER2 overexpression, especially in immunohistochemically equivocal cases, remains a challenge. Manual analysis of HER2 expression is dependent on the assessment of membrane staining as well as comparisons with positive controls. In spite of the strides that have been made to standardize the assessment process, intra- and inter-observer discrepancies in scoring is not uncommon. In this manuscript we describe a pathologist assisted, computer-based continuous scoring approach for increasing the precision and reproducibility of assessing imaged breast tissue specimens. Computer-assisted analysis on HER2 IHC is compared with manual scoring and fluorescence in situ hybridization results on a test set of 99 digitally imaged breast cancer cases enriched with equivocally scored (2+) cases. Image features are generated based on the staining profile of the positive control tissue and pixels delineated by a newly developed Membrane Isolation Algorithm. Evaluation of results was performed using Receiver Operator Characteristic (ROC) analysis. A computer-aided diagnostic approach has been developed using a membrane isolation algorithm and quantitative use of positive immunostaining controls. By incorporating internal positive controls into feature analysis a greater Area Under the Curve (AUC) in ROC analysis was achieved than feature analysis without positive controls. Evaluation of HER2 immunostaining that utilized membrane pixels, controls, and percent area stained showed significantly greater AUC than manual scoring, and significantly less false positive rate when used to evaluate immunohistochemically equivocal cases. It has been shown that by incorporating both a membrane isolation algorithm and analysis of known positive controls a computer-assisted diagnostic algorithm was

    Experimentation to greater understand the strangeness production mechanism can be performed by observing the electromagnetic interaction that leads to Kaon photoproduction. The n (γ, K^0) λ reaction may assist in answering questions about the strangeness photo-production process. An experiment into the elementary Kaon photoproduction process was investigated in an experiment conducted at the Laboratory of Nuclear Science of Tohoku University (LNS) using the Neutral Kaon Spectrometer. (NKS). The experiment was conducted by the d (γ, K^0) reaction. K^0 will be measured in the K^0->π^+π^- decay chain by the NKS. The NKS implements many detectors working in coincidence: These ranging from the Tagged Photon Beam generated by the 1.2 GeV Electron beam via bremsstrahlung, an Inner Plastic Scintillator Hodoscope (IH), a Straw Drift Chamber (SDC), a Cylindrical Drift Chamber (CDC), and an Outer Plastic Scintillator Hodoscope. Due to the background produced through the γ-> e+e- process, electron veto counters (EV) were placed in the middle of the OH to reject charged particles in the horizontal plane of the beam line. Preliminary analysis of the data indicates the need for pulse height correction. This was achieved by analysis of the Inner and Outer hodoscopes, and determining the energy deposit in the scintillators.

    To investigate the correlation between the counts per minute (CPM) by radioactivity assay and the phosphorylation ratio by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis, we prepared 136 peptide substrates. The correlation coefficient of phosphorylation ratios to CPM was 0.77 for all samples. However, the more the numbers of positively charged amino acids increased, the more the correlation coefficient increased. Although positively charged amino acids can have an effect on the correlation results, MALDI-TOF MS analysis is a useful means for monitoring phosphorylated peptide and protein kinase activity instead of radioactivity assays.

    Background. The aim of this study is to determine the correlation between computer-assisted diagnosis (CAD) of benign bone tumours (BBT) and their histological type. Patients and method. Altogether 120 patients were included in two groups. The retrospective group comprised 68 patients in whom the histological type of BBT was known prior to computer analysis. The prospective group comprised 52 patients in whom the histological type of BBT was unknown prior to computer analysis. Computer program was efficient and easy to use. Results. Average percent of histological type confirmed with CAD in the retrospective and prospective groups was 72.06% and 76.92%, respectively. Histological confirmation of CAD in specific BBT was 91.42% for enchondroma, 96.15% for osteoid-osteoma, and 98.08% for osteochondroma. Significantly lower percentage of CAD confirmation of fibroma, chondromixoid fibroma, osteoclastoma, desmoplastic fibroma and osteobalstoma due to their adverse biological character or complex anatomic localization is understandable. Conclusions. The results speak in favour of the assumption that computer assisted diagnosis of bone tumours program may improve the diagnostic accuracy of the examiner. (author)

    To analyse retrospectively the indications, technique and results of radiologically induced gastrostomies or enterostomies. Radiologically assisted gastrostomies or enterostomies were induced in 90 patients, mostly with high grade obstructions due to head and neck tumours or oesophageal tumours. 19/90 patients had had previous resection of the oesophagus or gastric operations. A catheter was successfully introduced in all patients. In 11/90 patients this was followed by a two-stage procedure. In 16/90 patients puncture was performed under CT control because of some anatomical peculiarity. Serious complication occurred in 9/90 patients but in only one was surgery necessary. There were no deaths resulting from the procedure but mortality after 30 days was 6.7%. Radiologically assisted gastrostomies or enterostomies are a reliable and effective form of treatment even amongst difficult patients. The results and complications are comparable to those from endoscopic procedures. (orig.) [de

    Highlights: Black-Right-Pointing-Pointer Hierarchical ZnO flowers were synthesized via a sucrose-assisted urea hydrothermal method. Black-Right-Pointing-Pointer The sucrose added ZnO flowers showed improved activity mainly due to the improved crystallinity. Black-Right-Pointing-Pointer The effect of sucrose content was studied and optimized. - Abstract: In this work, hierarchical ZnO flowers were synthesized via a sucrose-assisted urea hydrothermal method. The thermogravimetric analysis/differential thermal analysis (TGA-DTA) and Fourier transform infrared spectra (FTIR) showed that sucrose acted as a complexing agent in the synthesis process and assisted combustion during annealing. Photocatalytic activity was evaluated using the degradation of organic dye methyl orange. The sucrose added ZnO flowers showed improved activity, which was mainly attributed to the better crystallinity as confirmed by X-ray photoelectron spectroscopy (XPS) analysis. The effect of sucrose amount on photocatalytic activity was also studied.

    Paralytic ileus after laparoscopic-assisted surgery often occurs. We investigated whether daikenchuto (DKT), a traditional Japanese herbal medicine, improves intestinal motility in patients undergoing laparoscopic-assisted colectomy for colon cancer. Fifty-four patients who underwent colectomy at Iwate Medical University Hospital between October 2010 and March 2012 were randomized to either the DKT group (7.5 g/day, p.o.) or the control group (lactobacillus preparation, 3g/day, p.o.). Primary endpoints included time to first flatus, bowel movement, and tolerance of diet after extubation. Secondary endpoints were WBC count, C-reactive protein (CRP) level, length of hospital stay, and postoperative ileus. Colonic transit time was measured using radiopaque markers and abdominal radiographs. Fifty-one patients (DKT, 26 vs. control, 25) were included in the per-protocol analysis. The DKT group had significantly faster time until first flatus (67.5 +/- 13.6h vs. 77.9 +/- 11.8h, P DKT accelerates colonic motility in patients undergoing laparoscopic-assisted colectomy for colon cancer.

    Magnetic beads are often used for serum profiling of peptide and protein biomarkers. In these assays, the bead-bound analytes are eluted from the beads prior to mass spectrometric analysis. This study describes a novel matrix-assisted laser desorption/ionization (MALDI) technique for direct application and focusing of magnetic beads to MALDI plates by means of dedicated micro-magnets as sample spots. Custom-made MALDI plates with magnetic focusing spots were made using small nickel-coated neodymium micro-magnets integrated into a stainless steel plate in a 16 × 24 (384) pattern. For demonstrating the proof-of-concept, commercial C-18 magnetic beads were used for the extraction of a test compound (reserpine) from aqueous solution. Experiments were conducted to study focusing abilities, the required laser energies, the influence of a matrix compound, dispensing techniques, solvent choice and the amount of magnetic beads. Dispensing the magnetic beads onto the micro-magnet sample spots resulted in immediate and strong binding to the magnetic surface. Light microscope images illustrated the homogeneous distribution of beads across the surfaces of the magnets, when the entire sample volume containing the beads was pipetted onto the surface. Subsequent MALDI analysis of the bead-bound analyte demonstrated excellent and reproducible ionization yields. The surface-assisted laser desorption/ionization (SALDI) properties of the strongly light-absorbing γ-Fe2O3-based beads resulted in similar ionization efficiencies to those obtained from experiments with an additional MALDI matrix compound. This feasibility study successfully demonstrated the magnetic focusing abilities for magnetic bead-bound analytes on a novel MALDI plate containing small micro-magnets as sample spots. One of the key advantages of this integrated approach is that no elution steps from magnetic beads were required during analyses compared with conventional bead experiments.

    Women following unilateral oophorectomy (UO) are occasionally encountered during assisted reproduction treatment. To explore the impact of UO on ovarian reserve in assisted reproduction. An electronic database search was performed using PubMed, EBSCO, ISI, Trip, ClinicalTrial.gov and the Cochrane library followed by a manual search to identify published research between January 1978 and December 2015. Controlled studies that compared infertile women following UO undergoing IVF-ET treatment with women with two intact ovaries. Two reviewers independently extracted the data concerning the impact of UO on ovarian reserve tests, ovarian response to controlled ovarian hyperstimulation and clinical pregnancy rate. Meta-analysis was performed using these measures. Twenty-one studies were eligible for quantitative analysis. They included 1045 and 18 172 IVF cycles in women with one and two intact ovaries, respectively. Basal FSH weighted mean difference (WMD) was significant (2.01 IU/l; 95% CI: 0.24-3.79, P = 0.026). Similarly, the WMD of serum E 2 level on the day of hCG administration was significant (WMD: -431 pg/ml; 95% CI: -616 to -246, P < 0.001). However, the weighted overall odds ratio (OR) of clinical pregnancy between women with a single ovary and women with two ovaries was comparable (overall OR: 0.76; 95% CI: 0.57-1.00, P = 0.054). All eligible studies were retrospectively conducted and the heterogeneity among ovarian response measures was high. Available pooled data supports an adverse effect of UO on ovarian reserve involving the quantity but not the quality of the ovarian pool. Review finds women with one ovary removed have less IVF capacity but the same pregnancy rate as women with two ovaries. © 2017 Royal College of Obstetricians and Gynaecologists.

    Today, advances in technology provide the best success rates in the reproductive medicine field. One of the biggest concerns about it, is the high risk of achieving multiple pregnancies, which may carry greater health risks for both; the mother and fetuses. Besides that, multiple pregnancies are considered a complication or an adverse effect of assisted reproduction treatments. To compare the factors associated with multiple pregnancy in patients who underwent complex assisted reproduction techniques. A retrospective and transversal case control study was rolled to compare the factors associated with multiple pregnancy rates, these results were correlated using a logistic regression model. a total of 1063 cases were reviewed, we obtained a pregnancy rate of 35.9%, and a multiple pregnancy rate of 31.5%. We found positive statistical association between patient age, total number of oocytes obtained, total embryos transferred, total vitrified embryos per cycle, total serum cuantitative B-GCH level, endometrial thickness in milimeters, and the Honest of a multiple pregnancy. In the logistic regression model, we found statistical association between the number of embryos transferred, number of embryos obtained, embryo quality, total vitrified embryos and the risk for multiple pregnancies. The total number of embryos transferred in a cycle of a complex assisted reproduction, is the most important factor for the onset of multiple pregnancies. The age of patients, the number of oocytes, total number of embryos obtained, the number of embryos transferred, the quality of embryos transferred and the number of frozen embryos per cycle, correlate significantly with more risk for multiple pregnancies.

    A physician assistant home care (PAHC) program providing house calls was initiated to reduce hospital readmissions after adult cardiac surgery. The purpose of our study was to compare 30-day PAHC and pre-PAHC readmission rate, length of stay, and cost. Patients who underwent adult cardiac surgery in the 48 months from September 2008 through August 2012 were retrospectively reviewed using pre-PAHC patients as the control group. Readmission rate, length of stay, and health care cost, as measured by hospital billing, were compared between groups matched with propensity score. Of the 1,185 patients who were discharged directly home, 155 (13%) were readmitted. Total readmissions for the control group (n = 648) was 101 patients (16%) compared with the PAHC group (n = 537) total readmissions of 54 (10%), a 38% reduction in the rate of readmission (p = 0.0049). Propensity score matched groups showed a rate reduction of 41% with 17% (62 of 363) for the control compared with 10% (37 of 363) for the PAHC group (p = 0.0061). The average hospital bill per readmission was $39,100 for the control group and $56,600 for the PAHC group (p = 0.0547). The cost of providing home visits was $25,300 for 363 propensity score matched patients. The PAHC program reduced the 30-day readmission rate by 41% for propensity score matched patients. Analysis demonstrated a savings of $977,500 at a cost of $25,300 over 2 years, or $39 in health care saved, in terms of hospital billing, for every $1 spent. Therefore, a home visit by a cardiac surgical physician assistant is a cost-effective strategy to reduce readmissions after cardiac surgery. Copyright © 2016 The Society of Thoracic Surgeons.

    The GERDA (GERmanium Detector Array) experiment, located in the Gran Sasso Underground Laboratory (LNGS, Italy) aims to search for neutrinoless double beta (0νββ) decay of the 76Ge isotope. Both an ultra-low radioactivity background environment and active techniques to abate the residual background are required to reach the background index (of 10-3 counts/keV kg y) at the Qββ. In order to veto and suppress those events that partially deposit energy in Ge detectors, the readout of liquid argon (LAr) scintillation light (SL) has been implemented for the second GERDA experimental Phase. A double veto system has been designed and constructed using highly radiopure materials (scintillating fibers, wavelength shifters, polymeric foils, reflective foils).

    Robotic technology is increasingly prevalent in bariatric surgery, yet there are national deficiencies in exposure of surgical residents to robotic techniques. The purpose of this study is to accurately characterize the perioperative outcomes of a resident teaching model using the robotic-assisted sleeve gastrectomy. University Hospital. We identified 411 consecutive patients who underwent robotic sleeve gastrectomy at our institution from a prospectively maintained administrative database. Perioperative morbidity, operative time, and supply cost of the procedure were analyzed. Mean operative time was 96.4±24.9 minutes; mean robot usage time was 63.9 minutes (range 30.0-122.0 min). Ninety-day morbidities included reoperation (0.72%), major bleeding complications (0.48%), staple line leak (0.24%), stricture (0.97%), need for blood transfusion (3.86%), surgical site infection (1.69%), deep vein thrombosis (0.48%), and pulmonary embolism (0.48%). Mortality was nil. The resident cohort achieved operative time plateaus after five consecutive cases. Subset analysis for fiscal year 2014 demonstrated significantly increased supply cost for robotic sleeve gastrectomy compared with its laparoscopic equivalent. Robotic-assisted sleeve gastrectomy can be instituted as a model for resident robotic education with rates of morbidity and operative times equivalent to historical laparoscopic controls. The robot's enhanced ergonomics and its opportunity for resident education must be weighed against its increased supply cost. Copyright © 2016 American Society for Bariatric Surgery.

    The objective of the study was to evaluate the effect of different types of chambers used in computer-assisted semen analysis (CASA) on boar sperm concentration and motility parameters. CASA measurements were performed on 45 ejaculates by comparing three commonly used chambers: Leja chamber (LJ), Makler chamber (MK) and microscopic slide-coverslip (SL). Concentration results obtained with CASA were verified by manual counting on a Bürker hemocytometer (BH). No significant differences were found between the concentrations determined with BH vs. LJ and SL, whereas higher (p0.05). The results obtained show that CASA assessment of boar semen should account for the effect of counting chamber on the results of sperm motility and concentration, which confirms the need for further study on standardizing the automatic analysis of boar semen.

    To analyze results of the Horus Information System, comparing elements of this system with some international experiences. Horus is a technological innovation introduced in 2009 in the Pharmaceutical management information system of the Sistema Único de Saúde (Brazilian Unified Health System). In 2011, local managers and health professionals of 1,247 municipalities (16 states) that adhered to Horus answered questionnaires on pharmaceutical assistance in primary care and about the Horus system. This is a descriptive and exploratory study, developed with the use of quantitative and qualitative methods of research. Multivariate tools were used for data collection and interpretative support of the statistical inference and thematic analysis. The main changes identified after the implementation of this system were: improvement on technical and scientific quality control of Pharmaceutical Assistance, improvement on the supply of medications and health care; training of human resources and knowledge management; improvement on the relationship health managers/users; development in the administrative management and greater inter-state management; and improvement on the technological infrastructure. In terms of health information systems, these categories are consistent with programs and obstacles observed in international experiences. The biggest gap identified was the fact that Horus was not included in a national policy of health information systems, which is in a process of consolidation in Brazil. The national database of actions and services within the Pharmaceutical Assistance will enable the collection, analysis and dissemination of information regarding integrated pharmaceutical assistance in the Brazilian context. The Horus System is a technological innovation that enables the management of the Pharmaceutical Assistance. The national base will enable the definition and agreement on national indicators of Pharmaceutical Assistance, aiming to produce evidence of

    The aims were to explore advanced practice nurses' perceptions on wireless Personal Digital Assistant technologies, to establish the type and range of tools that would be useful to support their practice and to identify any requirements and limitations that may impact the implementation of wireless Personal Digital Assistants in practice. The wireless Personal Digital Assistant is becoming established as a hand-held computing tool for healthcare professionals. The reflections of advanced practice nurses' about the value of wireless Personal Digital Assistants and its potential to contribute to improved patient care has not been investigated. A qualitative interpretivist design was used to explore advanced practice nurses' perceptions on the value of wireless Personal Digital Assistant technologies to support their practice. The data were collected using survey questionnaires and individual and focus group interviews with nurse practitioners, clinical nurse specialists and information technology managers based in British Columbia, Canada. An open-coding content analysis was performed using qualitative data analysis software. Wireless Personal Digital Assistant's use supports the principles of pervasivity and is a technology rapidly being adopted by advanced practice nurses. Some nurses indicated a reluctance to integrate wireless Personal Digital Assistant technologies into their practices because of the cost and the short technological life cycle of these devices. Many of the barriers which precluded the use of wireless networks within facilities are being removed. Nurses demonstrated a complex understanding of wireless Personal Digital Assistant technologies and gave good rationales for its integration in their practice. Nurses identified improved client care as the major benefit of this technology in practice and the type and range of tools they identified included clinical reference tools such as drug and diagnostic/laboratory reference applications and wireless

  10. The psychosexual profile of sexual assistants: an internet-based explorative study.

    Full Text Available Sexual assistance may have some aspects that resemble prostitution and others that might lead one to think of sexual assistants as similar to a group of subjects whose sexual object is disability (devotees. In this study, we investigate whether a rigorous selection and training process on the part of specialised organisations may reduce the risk of training subjects with an atypical sexual interest and behaviours resembling prostitution.The study population consisted of 152 subjects defining themselves as sexual assistants. Subjects were initially contacted on websites specifically dedicated to sexual assistants and prostitutes. One hundred and twenty subjects were selected, by propensity score analysis, and studied by means of a modified version of a semi-structured questionnaire previously developed to investigate a population of subjects attracted by disability.The study group was composed of 80 trained and 40 untrained sexual assistants, with mean ages of 41.5 (SD +/-12.58 and 44.5 (SD +/-11.62, respectively. A significant number of untrained subjects affirmed that their motivation in carrying out sexual assistance was of a remunerative nature, while this number was lower among the trained assistants (p = 0.001. Nearly all untrained subjects claimed to do one or more of the following activities during sexual assistance: sexual intercourse, oral sex, and masturbation. Among the trained subjects, however, only 47.5% claimed to do one or more of these activities, which means that there is a significant gap between trained and untrained assistants (p<0.0001. The existence of an atypical sexual interest was more evident between untrained rather than between trained subjects (p<0.0001.Sexual assistance represents a way through which people affected by disabilities may attain the right to explore their sexuality in a safe setting. This can be guaranteed only if sexual assistants are trained and carefully selected by specialised organisations.

    Purpose and Objectives The National Early Care and Education Learning Collaboratives Project (ECELC) aims to improve best practices in early care and education (ECE) programs in topic areas of the Nutrition and Physical Activity Self-Assessment in Child Care (NAP SACC). Technical assistance is a component of the ECELC, yet its effect on outcomes is unclear. Beyond dose and duration of technical assistance, limited research exists on characteristics of technical assistance that contribute to outcomes. The objective of this study was to identify and describe technical assistance characteristics and explore associations with NAP SACC outcomes. Intervention Approach We collected data from 10 collaboratives comprising 84 ECE programs in 2 states in 2015–2016. The objective of technical assistance was to support programs in improving best practices. Technical assistance was provided to programs via on-site, telephone, or email and was tailored to program needs. Evaluation Methods We used a mixed-methods design to examine associations between technical assistance and NAP SACC outcomes. We used multiple regression analysis to assess quantitative data and qualitative comparative analysis to determine necessary and sufficient technical assistance conditions supporting NAP SACC outcomes. We also conducted a document review to describe technical assistance that referred conditions identified by the qualitative comparative analysis. Results Regression analyses detected an inverse relationship between changes in NAP SACC scores and hours of technical assistance. No clear pattern emerged in the qualitative comparative analysis, leaving no necessary and sufficient conditions. However, the qualitative comparative analysis identified feedback as a potentially important component of technical assistance, whereas resource sharing and frequent email were characteristics that seemed to reduce the likelihood of improved outcomes. Email and resource sharing were considered primarily

    BACKGROUND Letrozole is the third-generation aromatase inhibitor (AI) most widely used in assisted reproduction. AIs induce ovulation by inhibiting estrogen production; the consequent hypoestrogenic state increases GnRH release and pituitary follicle-stimulating hormone (FSH) synthesis. METHODS A systematic search of the literature was performed for both prospective and retrospective studies. Meta-analyses of randomized clinical trials (RCTs) were performed for three comparisons: letrozole versus clomiphene citrate (CC), letrozole + FSH versus FSH in intrauterine insemination (IUI) and letrozole + FSH versus FSH in IVF. In the absence of RCTs, non-randomized studies were pooled. RESULTS Nine studies were included in the meta-analysis. Four RCTs compared the overall effect of letrozole with CC in patients with polycystic ovary syndrome. The pooled result was not significant for ovulatory cycles (OR = 1.17; 95% CI 0.66–2.09), or for pregnancy rate per cycle (OR = 1.47; 95% CI 0.73–2.96) or for pregnancy rate per patient (OR = 1.37; 95% CI 0.70–2.71). In three retrospective studies which compared L + FSH with FSH in ovarian stimulation for IUI, the pooled OR was 1.15 (95% CI 0.78−1.71). A final meta-analysis included one RCT and one cohort study that compared letrozole + gonadotrophin versus gonadotrophin alone: the pooled pregnancy rate per patient was not significantly different (OR = 1.40; 95% CI 0.67–2.91). CONCLUSIONS Letrozole is as effective as other methods of ovulation induction. Further randomized-controlled studies are warranted to define more clearly the efficacy and safety of letrozole in human reproduction. PMID:18812422

    2010-05-01

    This study presents the design and development of a mobile wireless platform to be used for monitoring and analysis of seismic events and related electromagnetic (EM) signals, employing Personal Digital Assistants (PDAs). A prototype custom-developed application was deployed on a 3G enabled PDA that could connect to the FTP server of the Institute of Geodynamics of the National Observatory of Athens and receive and display EM signals at 4 receiver frequencies (3 KHz (E-W, N-S), 10 KHz (E-W, N-S), 41 MHz and 46 MHz). Signals may originate from any one of the 16 field-stations located around the Greek territory. Employing continuous recordings of EM signals gathered from January 2003 till December 2007, a Support Vector Machines (SVM)-based classification system was designed to distinguish EM precursor signals within noisy background. EM-signals corresponding to recordings preceding major seismic events (Ms≥5R) were segmented, by an experienced scientist, and five features (mean, variance, skewness, kurtosis, and a wavelet based feature), derived from the EM-signals were calculated. These features were used to train the SVM-based classification scheme. The performance of the system was evaluated by the exhaustive search and leave-one-out methods giving 87.2% overall classification accuracy, in correctly identifying EM precursor signals within noisy background employing all calculated features. Due to the insufficient processing power of the PDAs, this task was performed on a typical desktop computer. This optimal trained context of the SVM classifier was then integrated in the PDA based application rendering the platform capable to discriminate between EM precursor signals and noise. System's efficiency was evaluated by an expert who reviewed 1/ multiple EM-signals, up to 18 days prior to corresponding past seismic events, and 2/ the possible EM-activity of a specific region employing the trained SVM classifier. Additionally, the proposed architecture can form a

    Plant breeding is a way of selection of a particular individual for the production of the progeny by separating or combining desired characteristics. The objective of this study was to justify different characteristics of Dioscorea hispida (Ubi gadong) varieties using molecular techniques to select the best variety for sustainable production at the farmer's level. A total of 160 germplasms of Ubi gadong were collected from different locations at the Terengganu and Kelantan states of Malaysia. Forty eight (48) out of 160 germplasms were selected as "primary" selection based on yield and other qualitative characters. Selected collections were then grown and maintained for ISSR marker-assisted genetic diversity analysis. Overall plant growth and yield of tubers were also determined. A total of 12 ISSR markers were tested to justify the characteristics of Ubi gadong varieties among which three markers showed polymorphic bands and on average 57.3% polymorphism were observed representing the highest variation among germplasms. The ISSR marker based on UPGMA cluster analysis grouped all 48 D. hispida into 10 vital groups that proved a vast genetic variation among germplasm collections. Therefore, hybridization should be made between two distant populations. The D. hispida is already proved as the highest starch content tuber crops and very rich in vitamins with both micro and macro minerals. Considering all these criteria and results from marker-assisted diversity analysis, accessions that are far apart based on their genetic coefficient (like DH27 and DH71; DH30 and DH70; DH43 and DH62; DH45 and DH61; DH77 and DH61; DH78 and DH57) could be selected as parents for further breeding programs. This will bring about greater diversity, which will lead to high productive index in terms of increase in yield and overall quality and for the ultimate target of sustainable Ubi gadong production.

    Full Text Available The article analyzes the activities of assistant barristers and their role in the history of the Russian Bar system. In particular, the author proves the proposition that in practice assistant barristers were an independent part of the Bar system. They were both jurors and members of private attorney institutions. In this regard, the article describes the main activities of St. Petersburg Council of barristers concerning assistant barristers, in particular their status, legal education, forms of control of their daily practice, etc. Simultaneously, the author pays special attention to the analysis of the creation and improvement of the legal base for assistant barristers’ activities. In the author’s opinion, it was done up to 1917. Particular attentionis paid to the work of the Commission of assistant barristers related to establishing and holding legal conferences at which there were delivered lectures and discussed essays on various topical issues of law practice.

    Thin films of MgF sub 2 have been deposited by the ion-assisted electron-beam evaporation technique in order to find out the ion beam parameters leading to films of high laser damage threshold whose optical properties are stable under uncontrolled atmosphere conditions. It has been found that the ion-assisted electron-beam evaporation technique allows getting films with optical properties (refraction index and extinction coefficient) of high environmental stability by properly choosing the ion-source voltage and current. But, the laser damage fluence at 308 nm was quite dependent on the assisting ion beam parameters. Larger laser damage fluences have been found for the films deposited by using assisting ion beams delivered at lower anode voltage and current values. It has also been found that the films deposited without ion assistance were characterized by the highest laser damage fluence (5.9 J/cm sup 2) and the lowest environmental stability. The scanning electron microscopy analysis of the irradiated areas...

    The aim of the study was to describe healthy older couples' perceptions of using assistive technology services when needing assistance with care. The use of information technology-based assistive technology services in elder care has increased as a result of an increase of care performed in private homes. The use of assistive technology services in care of older people at home has been evaluated as something positive by patients, relatives and nursing staff, while as resistance to their increased use has also been noted. Twelve healthy couples, aged over 70 years, from northern Sweden were interviewed in 2005 about their perceptions of using assistive technology services in the case of being in need of assistance with personal care. Open, individual semi-structured interviews supported by written vignettes describing three levels of caring needs were used and the data analysed with content analysis. The findings were interpreted as one main theme with three categories: Asset or threat depends on caring needs and abilities. Three categories were identified within the theme: Assistive technology services provide an opportunity; The consequences of using assistive technology services are hard to anticipate; and Fear of assistive technology services when completely dependent on care. Trust and security in the care of older people who are severely ill, dependent on care and living at home should be a hallmark in using assistive technology services. Human presence is an important dimension and must be considered when developing concepts for use of assistive technology services.

    To determine the accuracy and precision of a novel computer-assisted sperm analysis (CASA) system by comparison with existing recommended manual methods. Prospective study using comparative measurements of sperm concentration and motility on latex beads and immotile and motile sperm. Tertiary referral fertility center with strong academic links. Sperm donors and male partners of couples attending for fertility investigations. None. Achievement of Accubead target value for high and low concentration suspensions. Repeatability as demonstrated by coefficients of variation and intraclass correlation coefficients. Correlation and limits of agreement between CASA and manual methods. The CASA measurements of latex beads and sperm concentrations demonstrated a high level of accuracy and repeatability. Repeated Accubead measurements attained the required target value (mean difference from target of 2.61% and 3.71% for high- and low-concentration suspensions, respectively) and were highly reproducible. Limits of agreement analysis suggested that manual and CASA counts compared directly could be deemed to be interchangeable. Manual and CASA motility measurements were highly correlated for grades a, b, and d but could not be deemed to be interchangeable, and manual motility estimates were consistently higher for motile sperm. The novel CASA system was able to provide semen quality measurements for sperm concentration and motility measurements which were at least as reliable as current manual methods.

    Gourlay, Barbara Elas

    This research project investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. During the fall semester, introductory-level chemistry lab sections of three experienced non-native speaking teaching assistants and their undergraduate students were observed. Digital audio and video recordings documented fifteen hours of lab communication, focusing on the activities and interactions in the first hour of the chemistry laboratory sessions. In follow-up one-on-one semi-structured interviews, the participants (undergraduates, teaching assistants, and faculty member) reviewed interactions and responded to a 10-item, 7-point Likert-scaled interview. Interactions were classified into success categories based on participants' opinions. Quantitative and qualitative data from the observations and interviews guided the analysis of the laboratory interactions, which examined patterns of conversational listening. Analysis of laboratory communication reveals that undergraduates initiated nearly two-thirds of laboratory communication, with three-fourths of interactions less than 30 seconds in duration. Issues of gender and topics of interaction activity were also explored. Interview data identified that successful undergraduate-teaching assistant communication in interactive science labs depends on teaching assistant listening comprehension skills to interpret and respond successfully to undergraduate questions. Successful communication in the chemistry lab depended on the coordination of visual and verbal sources of information. Teaching assistant responses that included explanations and elaborations were also seen as positive features in the communicative exchanges. Interaction analysis focusing on the listening comprehension demands placed on international teaching assistants revealed that undergraduate-initiated questions often employ deixis (exophoric reference), requiring teaching assistants to

    Computer-assisted methods of CT brain scan analysis offer considerable advantages over visual inspection, particularly in research; and several semi-automated methods are currently available. A new computer-assisted program is presented which provides fully automated processing of CT brain scans, depending on ''anatomical knowledge'' of where cerebrospinal fluid (CSF)-containing spaces are likely to lie. After identifying these regions of interest quantitative estimates are then provided of CSF content in each slice in cisterns, ventricles, Sylvian fissure and interhemispheric fissure. Separate measures are also provided of mean brain density in each slice. These estimates can be summated to provide total ventricular and total brain volumes. The program shows a high correlation with measures derived from mechanical planimetry and visual grading procedures, also when tested against a phantom brain of known ventricular volume. The advantages and limitations of the present program are discussed. (orig.)

    In the spring term of 2010, Oregon State University (OSU) began using a SCALE-UP style classroom in the instruction of the introductory calculus-based physics series. Instruction in this classroom was conducted in weekly two-hour sessions facilitated by the primary professor and either two graduate teaching assistants (GTAs) or a graduate teaching assistant and an undergraduate learning assistant (LA). During the course of instruction, two of the eight tables in the room were audio and video recorded. We examine the practices of the GTAs in interacting with the students through both qualitative and quantitative analyses of these recordings. Quantitatively, significant differences are seen between the most experienced GTA and the rest. A major difference in confidence is also observed in the qualitative analysis of this GTA compared to a less experienced GTA.

    In this paper we report on analysis toward identifying design requirements for an Adaptive Robotic Nursing Assistant (ARNA). Specifically, the paper focuses on application requirements for ARNA, envisioned as a mobile assistive robot that can navigate hospital environments to perform chores in roles such as patient sitter and patient walker. The role of a sitter is primarily related to patient observation from a distance, and fetching objects at the patient's request, while a walker provides physical assistance for ambulation and rehabilitation. The robot will be expected to not only understand nurse and patient intent but also close the decision loop by automating several routine tasks. As a result, the robot will be equipped with sensors such as distributed pressure sensitive skins, 3D range sensors, and so on. Modular sensor and actuator hardware configured in the form of several multi-degree-of-freedom manipulators, and a mobile base are expected to be deployed in reconfigurable platforms for physical assistance tasks. Furthermore, adaptive human-machine interfaces are expected to play a key role, as they directly impact the ability of robots to assist nurses in a dynamic and unstructured environment. This paper discusses required tasks for the ARNA robot, as well as sensors and software infrastructure to carry out those tasks in the aspects of technical resource availability, gaps, and needed experimental studies.

    This study sought to understand the extent to which students with severe disabilities receive assistive technology in school and out-of-school, and the relationship between receipt of assistive technology in school and post-school outcomes for these students. This study was a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2) from the USA. To analyze the data in this correlational study, researchers conducted frequency distributions, Chi Square Tests of Associations, significance tests and logistic regressions. The main results suggest (a) receipt of assistive technology in school varied greatly by disability identification; (b) receipt of assistive technology post-school also varied by disability identification, but receipt was generally lower; and (c) few statistically significant post-school outcome differences existed between students who received assistive technology and those who did not. An under-utilization of assistive technology exists in practice in the USA for students with severe disabilities. Implications for Rehabilitation An under-utilization of assistive technology for secondary students and adults with severe disabilities likely exists. A need exists for improved collaboration between professionals in rehabilitation and professionals in schools to ensure continuation of needed services or aids, such as assistive technology. Additional research is needed to better understand the adult life (or post-school) outcomes of individuals with severe disabilities, factors from PK-12 schooling or post-school services that positively and negative impact those outcomes.

    2017-01-01

    Studies of self-controlled practice have shown benefits when learners controlled feedback schedule, use of assistive devices and task difficulty, with benefits attributed to information processing and motivational advantages of self-control. Although haptic assistance serves as feedback, aids task performance and modifies task difficulty, researchers have yet to explore whether self-control over haptic assistance could be beneficial for learning. We explored whether self-control of haptic assistance would be beneficial for learning a tracing task. Self-controlled participants selected practice blocks on which they would receive haptic assistance, while participants in a yoked group received haptic assistance on blocks determined by a matched self-controlled participant. We inferred learning from performance on retention tests without haptic assistance. From qualitative analysis of open-ended questions related to rationales for/experiences of the haptic assistance that was chosen/provided, themes emerged regarding participants’ views of the utility of haptic assistance for performance and learning. Results showed that learning was directly impacted by the frequency of haptic assistance for self-controlled participants only and view of haptic assistance. Furthermore, self-controlled participants’ views were significantly associated with their requested haptic assistance frequency. We discuss these findings as further support for the beneficial role of self-controlled practice for motor learning. PMID:29255438

  10. A Geographic Information-Assisted Temporal Mixture Analysis for Addressing the Issue of Endmember Class and Endmember Spectra Variability

    2017-03-01

    Full Text Available Spectral mixture analysis (SMA is a common approach for parameterizing biophysical fractions of urban environment and widely applied in many fields. For successful SMA, the selection of endmember class and corresponding spectra has been assumed as the most important step. Thanks to the spatial heterogeneity of natural and urban landscapes, the variability of endmember class and corresponding spectra has been widely considered as the profound error source in SMA. To address the challenging problems, we proposed a geographic information-assisted temporal mixture analysis (GATMA. Specifically, a logistic regression analysis was applied to analyze the relationship between land use/land covers and surrounding socio-economic factors, and a classification tree method was used to identify the present status of endmember classes throughout the whole study area. Furthermore, an ordinary kriging analysis was employed to generate a spatially varying endmember spectra at all pixels in the remote sensing image. As a consequence, a fully constrained temporal mixture analysis was conducted for examining the fractional land use land covers. Results show that the proposed GATMA achieved a promising accuracy with an RMSE of 6.81%, SE of 1.29% and MAE of 2.6%. In addition, comparative analysis result illustrates that a significant accuracy improvement has been found in the whole study area and both developed and less developed areas, and this demonstrates that the variability of endmember class and endmember spectra is essential for unmixing analysis.

    Full Text Available The moment of the natural childbirth is a complex and dynamic event that demands assistance from the health professional that joins the humanized execution of procedures and actions respecting the singularity of the woman. In this way, the objectives of this study were: to know the main occurred complications at the moment of the natural childbirth and the assistance given by the nurse. It’s an exploratory research, in which the scene was a public hospital in the city of Jequié-Ba. The sampling consisted of five persons with specialization in obstetric nursing, and the used instrument for the data collection was the half-structuralized interview. After the data collection, the gotten information were submitted to the content analysis Bardin. Therefore, it’s possible to infer that the obstetric nurse faces in a positive way the complications lived deeply during the natural childbirth, through the exercise of a humanized and distinguished assistance as techniques/procedures endorsed by the literature. Thus, this can make us reflect the importance of this professional in the childbirth room as an executor and promoter of a worthy and welcoming assistance

    Digital image analysis (DIA) enables better reproducibility of immunohistochemistry (IHC) studies. Nevertheless, accuracy of the DIA methods needs to be ensured, demanding production of reference data sets. We have reported on methodology to calibrate DIA for Ki67 IHC in breast cancer tissue based on reference data obtained by stereology grid count. To produce the reference data more efficiently, we propose digital IHC wizard generating initial cell marks to be verified by experts. Digital images of proliferation marker Ki67 IHC from 158 patients (one tissue microarray spot per patient) with an invasive ductal carcinoma of the breast were used. Manual data (mD) were obtained by marking Ki67-positive and negative tumour cells, using a stereological method for 2D object enumeration. DIA was used as an initial step in stereology grid count to generate the digital data (dD) marks by Aperio Genie and Nuclear algorithms. The dD were collected into XML files from the DIA markup images and overlaid on the original spots along with the stereology grid. The expert correction of the dD marks resulted in corrected data (cD). The percentages of Ki67 positive tumour cells per spot in the mD, dD, and cD sets were compared by single linear regression analysis. Efficiency of cD production was estimated based on manual editing effort. The percentage of Ki67-positive tumor cells was in very good agreement in the mD, dD, and cD sets: regression of cD from dD (R2=0.92) reflects the impact of the expert editing the dD as well as accuracy of the DIA used; regression of the cD from the mD (R2=0.94) represents the consistency of the DIA-assisted ground truth (cD) with the manual procedure. Nevertheless, the accuracy of detection of individual tumour cells was much lower: in average, 18 and 219 marks per spot were edited due to the Genie and Nuclear algorithm errors, respectively. The DIA-assisted cD production in our experiment saved approximately 2/3 of manual marking. Digital IHC wizard

    Context: The graduate assistant athletic trainer (AT) position often serves as one's first experience working independently as an AT and is also an important aspect of the professional socialization process. The socialization experiences of graduate assistant ATs have yet to be fully explored. Objective: To understand the socialization process for graduate assistant ATs during their graduate experience. Design: Qualitative study. Setting: We conducted phone interviews with all participants. Patients or Other Participants: A total of 25 graduate assistant ATs (20 women, 5 men) studying in 1 of 3 academic tracks: (1) accredited postprofessional athletic training program (n = 8), (2) postprofessional athletic training program (n = 11), or (3) a nonathletic training degree program (n = 6). The average age was 25 ± 5 years, and the median age was 24 years. Participants were certified by the Board of Certification for an average of 2 ± 0.4 years. Data Collection and Analysis: We analyzed the data using a general inductive approach. Peer review, field notes, and intercoder reliability established trustworthiness. Data saturation guided participant recruitment. Results: The ability to gain clinical independence as a practitioner was an important socialization process. Having the chance to develop a relationship with a mentor, who provided support, guidance, and more of a hierarchical relationship, was an important socializing agent for the graduate assistant AT. Participants used the orientation session as a means to understand the expectations and role of the graduate-assistant position. Academic coursework was a way to achieve better inductance into the role via the opportunity to apply classroom skills during their clinical practice. Conclusions: Socializing the graduate assistant blends formal and informal processes. Transition to practice is a critical aspect of the profession; thus, supporting autonomous practice with directed mentoring can promote professional

    A major goal of heroin-assisted treatment in Switzerland has been to reduce the drug-related mortality of heroin users. Therefore, a continuous monitoring of deaths under treatment is essential. To assess mortality of participants in heroin-assisted treatment in Switzerland over a 7-year period from 1994 to 2000, and to compare this mortality to the general population and to other populations of opioid users, as reported in the literature. Estimation of person years under heroin-assisted treatment from the complete case registry of heroin-assisted treatment in Switzerland. Estimation of standardized mortality ratios comparing the population in treatment to the Swiss population (standardized to the year 2000). Over the 7-year period, the crude death rate of patients in heroin-assisted treatment, and including one month after discharge from treatment, was 1% per year. The standardized mortality ratio for the entire observation period was 9.7 (95% C.I. 7.3-12.8), with females having higher standardized mortality ratios (SMR 17.2) than males (SMR 8.4). There was no clear time trend. Mortality in heroin-assisted treatment was low compared to the mortality rate of Swiss opioid users 1990s (estimated to be between 2.5 and 3%). It was also low compared to mortality rates of opioid users in other maintenance treatments in other countries as reported in the literature. The SMR was also lower than that reported in the only meta-analysis in the literature: 13.2 (95% C.I. 12.3-14.1). The low mortality rate is all the more noteworthy as heroin-assisted treatment in Switzerland included only refractory opioid addicts with existing severe somatic and/or mental problems. No conflicts of interest declared.

    2015-06-01

    We present a detailed phenomenological analysis of the production of a Standard Model Higgs boson in association with up to three jets. We consider the gluon fusion channel using an effective theory in the large top-quark mass limit. Higgs boson production in gluon fusion constitutes an irreducible background to the vector boson fusion (VBF) process; hence the precise knowledge of its characteristics is a prerequisite for any measurement in the VBF channel. The calculation is carried out at next-to-leading order (NLO) in QCD in a fully automated way by combining the two programs GoSam and Sherpa. We present numerical results for a large variety of observables for both standard cuts and VBF selection cuts. We find that for all jet multiplicities the NLO corrections are sizeable. This is particularly true in the presence of kinematic selections enhancing the VBF topology, which are based on vetoing additional jet activity. In this case, precise predictions for the background can be made using our calculation by taking the difference between the inclusive H+2 jets and the inclusive H+3 jets result.

    The Integrated Radiation Mapper Assistant (IRMA) system combines state-of-the-art radiation sensors and microprocessor based analysis techniques to perform radiation surveys. Control of the survey function is from a control station located outside the radiation thus reducing time spent in radiation areas performing radiation surveys. The system consists of a directional radiation sensor, a laser range finder, two area radiation sensors, and a video camera mounted on a pan and tilt platform. THis sensor package is deployable on a remotely operated vehicle. The outputs of the system are radiation intensity maps identifying both radiation source intensities and radiation levels throughout the room being surveyed. After completion of the survey, the data can be removed from the control station computer for further analysis or archiving.

    Computer-assisted semen analysis (CASA) is primarily used to obtain accurate and objective kinetic sperm measurements. Additionally, AI centers use computer-assessed sperm concentration in the sample as a basis for calculating the number of insemination doses available from a given ejaculate. The reliability of data is often limited and results can vary even when the same CASA systems with identical settings are used. The objective of the present study was to develop a computer-based training module for standardized measurements with a CASA system and to evaluate its training effect on the quality of the assessment of sperm motility and concentration. A digital versatile disc (DVD) has been produced showing the standardization of sample preparation and analysis with the CASA system SpermVision™ version 3.0 (Minitube, Verona, WI, USA) in words, pictures, and videos, as well as the most probable sources of error. Eight test persons educated in spermatology, but with different levels of experience with the CASA system, prepared and assessed 10 aliquots from one prediluted bull ejaculate using the same CASA system and laboratory equipment before and after electronic learning (e-learning). After using the e-learning application, the coefficient of variation was reduced on average for the sperm concentration from 26.1% to 11.3% (P ≤ 0.01), and for motility from 5.8% to 3.1% (P ≤ 0.05). For five test persons, the difference in the coefficient of variation before and after use of the e-learning application was significant (P ≤ 0.05). Individual deviations of means from the group mean before e-learning were reduced compared with individual deviations from the group mean after e-learning. According to a survey, the e-learning application was highly accepted by users. In conclusion, e-learning presents an effective, efficient, and accepted tool for improvement of the precision of CASA measurements. This study provides a model for the standardization of other

    2014-12-01

    In this study, we consider a relay-assisted free-space optical communication scheme over strong atmospheric turbulence channels with misalignment-induced pointing errors. The links from the source to the destination are assumed to be all-optical links. Assuming a variable gain relay with amplify-and-forward protocol, the electrical signal at the source is forwarded to the destination with the help of this relay through all-optical links. More specifically, we first present a cumulative density function (CDF) analysis for the end-to-end signal-to-noise ratio. Based on this CDF, the outage probability, bit-error rate, and average capacity of our proposed system are derived. Results show that the system diversity order is related to the minimum value of the channel parameters.

    Although ECG interpretation is an essential skill in clinical medicine, medical students and residents often lack ECG competence. Novel teaching methods are increasingly being implemented and investigated to improve ECG training. Computer-assisted instruction is one such method under investigation; however, its efficacy in achieving better ECG competence among medical students and residents remains uncertain. This article describes the protocol for a systematic review and meta-analysis that will compare the effectiveness of computer-assisted instruction with other teaching methods used for the ECG training of medical students and residents. Only studies with a comparative research design will be considered. Articles will be searched for in electronic databases (PubMed, Scopus, Web of Science, Academic Search Premier, CINAHL, PsycINFO, Education Resources Information Center, Africa-Wide Information and Teacher Reference Center). In addition, we will review citation indexes and conduct a grey literature search. Data extraction will be done on articles that met the predefined eligibility criteria. A descriptive analysis of the different teaching modalities will be provided and their educational impact will be assessed in terms of effect size and the modified version of Kirkpatrick framework for the evaluation of educational interventions. This systematic review aims to provide evidence as to whether computer-assisted instruction is an effective teaching modality for ECG training. It is hoped that the information garnered from this systematic review will assist in future curricular development and improve ECG training. As this research is a systematic review of published literature, ethical approval is not required. The results will be reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement and will be submitted to a peer-reviewed journal. The protocol and systematic review will be included in a PhD dissertation. CRD

    These studies are part of a project aiming to reveal relevant aspects of human-dog interactions, which could serve as a model to design successful human-robot interactions. Presently there are no successfully commercialized assistance robots, however, assistance dogs work efficiently as partners for persons with disabilities. In Study 1, we analyzed the cooperation of 32 assistance dog-owner dyads performing a carrying task. We revealed typical behavior sequences and also differences depending on the dyads' experiences and on whether the owner was a wheelchair user. In Study 2, we investigated dogs' responses to unforeseen difficulties during a retrieving task in two contexts. Dogs displayed specific communicative and displacement behaviors, and a strong commitment to execute the insoluble task. Questionnaire data from Study 3 confirmed that these behaviors could successfully attenuate owners' disappointment. Although owners anticipated the technical competence of future assistance robots to be moderate/high, they could not imagine robots as emotional companions, which negatively affected their acceptance ratings of future robotic assistants. We propose that assistance dogs' cooperative behaviors and problem solving strategies should inspire the development of the relevant functions and social behaviors of assistance robots with limited manual and verbal skills.

    Full Text Available Abstract Background Breast cancers that overexpress the human epidermal growth factor receptor 2 (HER2 are eligible for effective biologically targeted therapies, such as trastuzumab. However, accurately determining HER2 overexpression, especially in immunohistochemically equivocal cases, remains a challenge. Manual analysis of HER2 expression is dependent on the assessment of membrane staining as well as comparisons with positive controls. In spite of the strides that have been made to standardize the assessment process, intra- and inter-observer discrepancies in scoring is not uncommon. In this manuscript we describe a pathologist assisted, computer-based continuous scoring approach for increasing the precision and reproducibility of assessing imaged breast tissue specimens. Methods Computer-assisted analysis on HER2 IHC is compared with manual scoring and fluorescence in situ hybridization results on a test set of 99 digitally imaged breast cancer cases enriched with equivocally scored (2+ cases. Image features are generated based on the staining profile of the positive control tissue and pixels delineated by a newly developed Membrane Isolation Algorithm. Evaluation of results was performed using Receiver Operator Characteristic (ROC analysis. Results A computer-aided diagnostic approach has been developed using a membrane isolation algorithm and quantitative use of positive immunostaining controls. By incorporating internal positive controls into feature analysis a greater Area Under the Curve (AUC in ROC analysis was achieved than feature analysis without positive controls. Evaluation of HER2 immunostaining that utilized membrane pixels, controls, and percent area stained showed significantly greater AUC than manual scoring, and significantly less false positive rate when used to evaluate immunohistochemically equivocal cases. Conclusion It has been shown that by incorporating both a membrane isolation algorithm and analysis of known

    The purpose of this study was to investigate consistency of performance of robot-assisted surgical tasks in a virtual reality environment. Eight subjects performed two surgical tasks, bimanual carrying and needle passing, with both the da Vinci surgical robot and a virtual reality equivalent environment. Nonlinear analysis was utilized to evaluate consistency of performance by calculating the regularity and the amount of divergence in the movement trajectories of the surgical instrument tips. Our results revealed that movement patterns for both training tasks were statistically similar between the two environments. Consistency of performance as measured by nonlinear analysis could be an appropriate methodology to evaluate the complexity of the training tasks between actual and virtual environments and assist in developing better surgical training programs.

    We study WZ production with anomalous couplings (AC) at anti nNLO QCD using the LoopSim method in combination with the Monte Carlo program VBFNLO. Higher order corrections to WZ production are dominated by additional hard jet radiation. Those contributions are insensitive to AC and should thus be suppressed in analyses. We do this using a dynamical jet veto based on the transverse energy of the QCD and EW final state particles. This removes jet dominated events without introducing problematic logs like a fixed p{sub T} jet veto.

    Financing for malaria control has increased as part of international commitments to achieve the Millennium Development Goals (MDGs). We aimed to identify the unmet financial needs that would be biologically and economically equitable and would increase the chances of reaching worldwide malaria-control ambitions. Populations at risk of stable Plasmodium falciparum or Plasmodium vivax transmission were calculated for 2007 and 2009 for 93 malaria-endemic countries to measure biological need. National per-person gross domestic product (GDP) was used to define economic need. An analysis of external donor assistance for malaria control was done for the period 2002-09 to compute overall and annualised per-person at-risk-funding commitments. Annualised malaria donor assistance was compared with independent predictions of funding needed to reach international targets of 80% coverage of best practices in case-management and effective disease prevention. Countries were ranked in relation to biological, economic, and unmet needs to examine equity and adequacy of support by 2010. International financing for malaria control has increased by 166% (from $0·73 billion to $1·94 billion) since 2007 and is broadly consistent with biological needs. African countries have become major recipients of external assistance; however, countries where P vivax continues to pose threats to control ambitions are not as well funded. 21 countries have reached adequate assistance to provide a comprehensive suite of interventions by 2009, including 12 countries in Africa. However, this assistance was inadequate for 50 countries representing 61% of the worldwide population at risk of malaria-including ten countries in Africa and five in Asia that coincidentally are some of the poorest countries. Approval of donor funding for malaria control does not correlate with GDP. Funding for malaria control worldwide is 60% lower than the US$4·9 billion needed for comprehensive control in 2010; this includes

    Robot-assisted radical cystectomy (RARC) is increasing annually for treatment of bladder cancer. The objective of this meta-analysis was to compare the safety and efficacy of RARC and open radical cystectomy (ORC) for bladder cancer. Our meta-analysis searches were conducted using PubMed, Web of Science, and Cochrane Library databases to identify randomized controlled trials (RCT) assessing the two techniques. Four RCT studies were identified, including 239 cases. Our studies indicated that RARC was associated with longer operative time (WMD: 69.69, 95% CI:17.25 to122.12; P= 0.009), lower estimated blood loss (WMD: -299.83, 95% CI:-414.66to -184.99; P<0.00001). The two groups had no significant difference in overall perioperative complications, length of hospital stay, lymph node yield and positive surgical margins. RARC is mini-invasive alternative to ORC for bladder cancer. The advantage of RARC was reduced estimated blood loss. More studies are needed to compare the two techniques.

    Millennium Development Goal 5 calls for increasing proportions of deliveries assisted by skilled health personnel to reduce maternal mortality. This study aims to identifying the implication of exposure to intimate partner violence on these proportions. This study used domestic violence modules data of Demographic and Health Surveys of six countries from 2005 to 2007. Proportions of assisted deliveries were examined by sociodemographic characteristics and exposure to intimate partner violence in the studied countries. Influence on the proportion was examined against exposure to intimate partner violence through odds ratio and 95% of logistic regression analysis after controlling for women age, residence (urban/rural), household wealth level, economic level of country, educational level and working status of women and their husbands/partners. Data sets of 18,507 participants over 20 years of age showed that almost three-quarters (73%) of women had deliveries assisted by skilled health personnel. One-third of the women were ever exposed to intimate partner violence (37%) and 9% of them to the severe level. Exposure to intimate partner violence statistically significantly lowered this proportion to 69% (odds ratio: 0.73; 95% confidence interval: 0.67-0.78) meanwhile severe violence lowered it to 65% (odds ratio 0.64; 95% confidence interval: 0.58-0.72). When running multiple regression analysis, exposure to intimate partner violence retained its statistically significant decreasing influence on proportions and was not biased by the other stronger socioeconomic characteristics. Intimate partner violence has an independent influence on reducing assisted deliveries by skilled health personnel. Programs working for increasing proportions of assisted deliveries by skilled health personnel are recommended to integrate protection women from violence.

    Introduction Sexual assistance may have some aspects that resemble prostitution and others that might lead one to think of sexual assistants as similar to a group of subjects whose sexual object is disability (devotees). In this study, we investigate whether a rigorous selection and training process on the part of specialised organisations may reduce the risk of training subjects with an atypical sexual interest and behaviours resembling prostitution. Materials and Methods The study population consisted of 152 subjects defining themselves as sexual assistants. Subjects were initially contacted on websites specifically dedicated to sexual assistants and prostitutes. One hundred and twenty subjects were selected, by propensity score analysis, and studied by means of a modified version of a semi-structured questionnaire previously developed to investigate a population of subjects attracted by disability. Results The study group was composed of 80 trained and 40 untrained sexual assistants, with mean ages of 41.5 (SD +/−12.58) and 44.5 (SD +/−11.62), respectively. A significant number of untrained subjects affirmed that their motivation in carrying out sexual assistance was of a remunerative nature, while this number was lower among the trained assistants (p = 0.001). Nearly all untrained subjects claimed to do one or more of the following activities during sexual assistance: sexual intercourse, oral sex, and masturbation. Among the trained subjects, however, only 47.5% claimed to do one or more of these activities, which means that there is a significant gap between trained and untrained assistants (p<0.0001). The existence of an atypical sexual interest was more evident between untrained rather than between trained subjects (p<0.0001). Conclusions Sexual assistance represents a way through which people affected by disabilities may attain the right to explore their sexuality in a safe setting. This can be guaranteed only if sexual assistants are trained and

    Robot-mediated therapy (RMT) has been a very dynamic area of research in recent years. Robotics devices are in fact capable to quantify the performances of a rehabilitation task in treatments of several disorders of the arm and the shoulder of various central and peripheral etiology. Different systems for robot-aided neuro-rehabilitation are available for upper limb rehabilitation but the biomechanical parameters proposed until today, to evaluate the quality of the movement, are related to the specific robot used and to the type of exercise performed. Besides, none study indicated a standardized quantitative evaluation of robot assisted upper arm reaching movements, so the RMT is still far to be considered a standardised tool. In this paper a quantitative kinematic assessment of robot assisted upper arm reaching movements, considering also the effect of gravity on the quality of the movements, is proposed. We studied a group of 10 healthy subjects and results indicate that our advised protocol can be useful for characterising normal pattern in reaching movements.

    2009-11-01

    The aim of this study was to investigate the experiences of persons with severe functional disabilities who receive personal assistance in their homes, the focus being on their daily life in relation to the ethical principles represented in the Swedish Disability Act: autonomy, integrity, influence and participation. Qualitative interviews were performed with 26 persons and thereafter subjected to qualitative latent content analysis. The experiences of personal assistance were very much in accordance with the said principles, the most important factor being that one is met with understanding. The participants described situations in which their integrity was violated in that they were not treated as competent adults. This indicates the importance of future efforts in nursing to support personal assistants with ethical knowledge and supervision so that they can empower people with disabilities and thereby enable them to maintain their self-esteem and dignity.

    2014-03-01

    Walker devices are often prescribed incorrectly to patients, leading to the increase of dissatisfaction and occurrence of several problems, such as, discomfort and pain. Thus, it is necessary to objectively evaluate the effects that assisted gait can have on the gait patterns of walker users, comparatively to a non-assisted gait. A gait analysis, focusing on spatiotemporal and kinematics parameters, will be issued for this purpose. However, gait analysis yields redundant information that often is difficult to interpret. This study addresses the problem of selecting the most relevant gait features required to differentiate between assisted and non-assisted gait. For that purpose, it is presented an efficient approach that combines evolutionary techniques, based on genetic algorithms, and support vector machine algorithms, to discriminate differences between assisted and non-assisted gait with a walker with forearm supports. For comparison purposes, other classification algorithms are verified. Results with healthy subjects show that the main differences are characterized by balance and joints excursion in the sagittal plane. These results, confirmed by clinical evidence, allow concluding that this technique is an efficient feature selection approach. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available In 2014, the Polish non-governmental patient association ‘Our Stork’ (Nasz Bocian introduced the ‘Patient monitoring in ART centres’ research project to gather previously unrecorded information on the situation of infertile people and the provision of assisted reproductive treatment in Poland. When the research project began, assisted reproductive treatment centres were unregulated by the state, a situation that had existed for more than 28 years following the birth of the first Polish test-tube baby in 1987. Patients signed civil contracts, remaining unprotected in terms of safety of treatment and recognition of their rights, and their presumed social position was described by doctors as ‘disciplined patients’ – a reflection of what Michele Foucault described as biopolitics. The research project comprised patient questionnaires (responses from 722 patients provided the basis for the document ‘Patient Recommendations in Infertility Treatment’, analysis of civil contracts and their accuracy in the context of patients’ legal rights in Poland, and in-depth interviews with assisted reproductive treatment centres’ owners, doctors, midwives, and patients to explore patient care. The data reveal that there is a lack of patient-centred care among doctors and medical staff in Poland and that following the passing into law of the 2015 Infertility Act, which introduced state regulation of assisted reproductive treatment centres, the situation for patients worsened.

    To examine whether racial, gender, and ethnic salary disparities exist in the physician assistant (PA) profession and what factors, if any, are associated with the differentials. We use a nationally representative survey of 15,105 PAs from the American Academy of Physician Assistants (AAPA). We use bivariate and multivariate statistics to analyze pay differentials from the 2009 AAPA survey. Women represent nearly two-thirds of the profession but receive approximately $18,000 less in primary compensation. The differential reduces to just over $9,500 when the analysis includes a variety of other variables. According to AAPA survey, minority PAs tend to make slightly higher salaries than White PAs nationally, although the differences are not statistically significant once the control variables are included in the analysis. Despite the rough parity in primary salary, PAs of color are vastly underrepresented in the profession. The salaries of women lag in comparison to their male counterparts. © Health Research and Educational Trust.

  6. Polymer-Assisted Hydrothermal Synthesis of Hierarchically Arranged Hydroxyapatite Nanoceramic

    Full Text Available Flower-like hydroxyapatite (HA nanostructures were synthesized by a polymer-assisted hydrothermal method. The thickness of the petals/plates decreased from 200 nm to 40 nm as the polymer concentration increased. The thickness also decreased as the hydrothermal treatment time increased from 6 to 12 hr. The HRTEM and SAED patterns suggest that the floral-like HA nanostructures are single crystalline in nature. Structural analysis based on XRD and Raman experiments implied that the produced nanostructure is a pure form of HA without any other impurities. The possible formation mechanism was discussed for the formation of flower-like HA nanostructures during polymer-assisted hydrothermal synthesis. Finally, in vitro cellular analysis revealed that the hierarchically arranged HA nanoceramic had improved cell viability relative to other structures. The cells were actively proliferated over these nanostructures due to lower cytotoxicity. Overall, the size and the crystallinity of the nanostructures played a role in improving the cell proliferation.

    Many different laboratories are currently developing mass-spectrometric techniques to analyze and identify microorganisms. However, minimal work has been done with mixtures of bacteria. To demonstrate that microbial mixtures could be analyzed by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), mixed bacterial cultures were analyzed in a double-blind fashion. Nine different bacterial species currently in our MALDI-MS fingerprint library were used to generate 50 different simulated mixed bacterial cultures similar to that done for an initial blind study previously reported.(1) The samples were analyzed by MALDI-MS with automated data extraction and analysis algorithms developed in our laboratory. The components present in the sample were identified correctly to the species level in all but one of the samples. However, correctly eliminating closely related organisms was challenging for the current algorithms, especially in differentiating Serratia marcescens, Escherichia coli, and Yersinia enterocolitica, which have some similarities in their MALDI-MS fingerprints. Efforts to improve the specificity of the algorithms are in progress.

    In this study, microwave irradiation has been employed to disintegrate the sludge biomass profitably by deagglomerating the sludge using a mechanical device, ultrasonicator. The outcomes of the study revealed that a specific energy input of 3.5 kJ/kg TS was found to be optimum for deagglomeration with limited cell lysis. A higher suspended solids (SS) reduction and biomass lysis efficiency of about 22.5% and 33.2% was achieved through ultrasonic assisted microwave disintegration (UMWD) when compared to microwave disintegration - MWD (15% and 20.9%). The results of biochemical methane potential (BMP) test were used to estimate biodegradability of samples. Among the samples subjected to BMP, UMWD showed better amenability towards anaerobic digestion with higher methane production potential of 0.3 L/g COD representing enhanced liquefaction potential of disaggregated sludge biomass. Economic analysis of the proposed method of sludge biomass pretreatment showed a net profit of 2.67 USD/Ton respectively. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2010-01-01

    The Fort Collins Science Center's Policy Analysis and Science Assistance (PASA) Branch is a team of approximately 22 scientists, technicians, and graduate student researchers. PASA provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and biological analyses in the context of human-natural resource interactions. Resource planners, managers, and policymakers in the U.S. Departments of the Interior (DOI) and Agriculture (USDA), State and local agencies, as well as international agencies use information from PASA studies to make informed natural resource management and policy decisions. PASA scientists' primary functions are to conduct both theoretical and applied social science research, provide technical assistance, and offer training to advance performance in policy relevant research areas. Management and research issues associated with human-resource interactions typically occur in a unique context, involve difficult to access populations, require knowledge of both natural/biological science in addition to social science, and require the skill to integrate multiple science disciplines. In response to these difficult contexts, PASA researchers apply traditional and state-of-the-art social science methods drawing from the fields of sociology, demography, economics, political science, communications, social-psychology, and applied industrial organization psychology. Social science methods work in concert with our rangeland/agricultural management, wildlife, ecology, and biology capabilities. The goal of PASA's research is to enhance natural resource management, agency functions, policies, and decision-making. Our research is organized into four broad areas of study.

    Community health nurses (CHNs), as leaders in developing countries, can promote successful outcomes in meeting the targets of the Millennium Development Goals. A community-based organization in Pakistan is striving to achieve the goals of maternal and child health through the development of the assistant manager role for community health nursing. The purpose of this study was to assess the perception of the role of the CHN assistant manager, with the goal of strengthening that role. This interpretive, qualitative study included 13 participants already familiar with CHNs in Pakistan. Interviewing was utilized to explore perceptions of the assistant manager role and to uncover challenges currently existing within this new role. Content analysis revealed the following themes: 'role perceptions', 'expectations of the role' and 'collaboration with other community healthcare providers'. Changes to the role are necessary including increased education of the assistant manager CHNs and preparing administration to work with the assistant mangers for effective leadership. © 2011 The Authors.

    Soxhlet extraction, ultrasound-assisted extraction (USAE) and microwaves-assisted extraction (MAE) in closed system have been investigated to determine the content of coumarin, o-coumaric and melilotic acids in flowering tops of Melilotus officinalis. The extracts were analyzed with an appropriate HPLC procedure. The reproducibility of extraction and of chromatographic analysis was proved. Taking into account the extraction yield, the cost and the time, we studied the effects of extraction variables on the yield of the above-mentioned compounds. Better results were obtained with MAE (50% v/v aqueous ethanol, two heating cycles of 5 min, 50 degrees C). On the basis of the ratio extraction yield/extraction time, we therefore propose MAE as the most efficient method.

    Full Text Available Laser microdissection followed by mass spectrometry has been successfully used for amyloid typing. However, sample contamination can interfere with proteomic analysis, and overnight digestion limits the analytical throughput. Moreover, current quantitative analysis methods are based on the spectrum count, which ignores differences in protein length and may lead to misdiagnoses. Here, we developed a microwave-assisted filter-aided sample preparation (maFASP method that can efficiently remove contaminants with a 10-kDa cutoff ultrafiltration unit and can accelerate the digestion process with the assistance of a microwave. Additionally, two parameters (P- and D-scores based on the exponentially modified protein abundance index were developed to define the existence of amyloid deposits and those causative proteins with the greatest abundance. Using our protocol, twenty cases of systemic amyloidosis that were well-typed according to clinical diagnostic standards (training group and another twenty-four cases without subtype diagnoses (validation group were analyzed. Using this approach, sample preparation could be completed within four hours. We successfully subtyped 100% of the cases in the training group, and the diagnostic success rate in the validation group was 91.7%. This maFASP-aided proteomic protocol represents an efficient approach for amyloid diagnosis and subtyping, particularly for serum-contaminated samples.

    Individuals with walking limitations often experience challenges engaging in functionally relevant exercise. An adapted elliptical trainer (motor to assist pedal movement, integrated body weight harness, ramps/stairs, and grab rails) has been developed to help individuals with physical disabilities and chronic conditions regain/retain walking capacity and fitness. However, limited published studies are available to guide therapeutic interventions. This repeated measures study examined the influence of motor-assisted elliptical training speed on lower extremity muscle demands at four body weight support (BWS) levels commonly used therapeutically for walking. Electromyography (EMG) and pedal trajectory data were recorded as ten individuals without known disability used the motor-assisted elliptical trainer at three speeds [20,40, 60 revolutions per minute (RPM)] during each BWS level (0%, 20%, 40%, 60%). Overall, the EMG activity (peak, mean, duration) in key stabilizer muscles (i.e., gluteus medius, gluteus maximus, vastus lateralis, medial gastrocnemius and soleus) recorded at 60 RPM exceeded those at 40 RPM, which were higher than values at 20 RPM in all but three situations (gluteus medius mean at 0% BWS, vastus lateralis mean at 20% BWS, soleus duration at 40% BWS); however, these differences did not always achieve statistical significance. Slower motor-assisted speeds can be used to accommodate weakness of gluteus medius, gluteus maximus, vastus lateralis, medial gastrocnemius and soleus. As strength improves, training at faster motor-assisted speeds may provide a means to progressively challenge key lower extremity stabilizers. Copyright © 2013 Elsevier B.V. All rights reserved.

    Summative content analysis was used to define methods and heuristics from each case study. The review process was in two parts: (1) A literature review to identify conventional research methods and (2) a summative content analysis of published case studies, based on the identified methods and heuristics to suggest an order and priority of where and when were used. Over 200 research and design methods and design heuristics were identified. From the review of the 20 case studies 42 were identified as being applied. The majority of methods and heuristics were applied in phase two, market choice. There appeared a disparity between the limited numbers of methods frequently used, under 10 within the 20 case studies, when hundreds were available. Implications for Rehabilitation The communication highlights a number of issues that have implication for those involved in assistive technology new product development: •The study defined over 200 well-established research and design methods and design heuristics that are available for use by those who specify and design assistive technology products, which provide a comprehensive reference list for practitioners in the field; •The review within the study suggests only a limited number of research and design methods are regularly used by industrial design focused assistive technology new product developers; and, •Debate is required within the practitioners working in this field to reflect on how a wider range of potentially more effective methods and heuristics may be incorporated into daily working practice.

  18. Cell-assisted lipotransfer: Friend or foe in fat grafting? Systematic review and meta-analysis.

    Autologous fat grafting is a common procedure for soft-tissue reconstruction but is associated with a graft resorption rate ranging from 20% to 80%. To improve the fat graft survival rate, a new technique, called cell-assisted lipotransfer (CAL), was developed. With CAL, fat is injected along with adipose-derived stromal cells that are assumed to improve fat survival rate. We conducted an evidence-based meta-analysis to evaluate the efficacy and safety of CAL as compared with conventional autologous fat grafting (non-CAL). The databases MEDLINE (via PubMed), Cochrane Library, EBSCO, Web of Science, and EMBASE were searched for reports of clinical trials, case series, and cohorts available from 2008 to 2016. We conducted a meta-analysis of the efficacy of CAL with data analysis concerning fat survival rate. The incidence of complications and the need for multiple procedures were evaluated to determine the safety of CAL. We identified 25 studies (696 patients) that were included in the systematic review; 16 studies were included in the meta-analysis to evaluate the efficacy of CAL. The fat survival rate was significantly higher with CAL than non-CAL (64% vs. 44%, p < .0001) independent of injection site (breast and face). This benefit of CAL was significant for only injection volumes <100 ml (p = .03). The two groups did not differ in frequency of multiple procedures after fat grafting, but the incidence of complications was greater with CAL than non-CAL (8.4% vs. 1.5%, p = .0019). The CAL method is associated with better fat survival rate than with conventional fat grafting but only for small volumes of fat grafting (<100 ml). Nonetheless, the new technique is associated with more complications and did not reduce the number of surgical procedures needed after the first fat grafting. More prospective studies are required to draw clinical conclusions and to demonstrate the real benefit of CAL as compared with common autologous fat grafting. Copyright © 2017

The procedures in these countries are largely based on voluntarism, but differ in their approach to public consultation as they were based on the so-called staged volunteer process leading to working partnership arrangements between the operator and the hosting communities and veto rights (Sweden), decisions with strong local community support and veto rights for municipalities until the final decision (Finland), and final top-down decision making after consultative processes (debat public) with the affected communities without veto rights (France). This presentation focuses on participation and acceptance issues; it analyses the different modes of governance with diverse conditions regarding transparency, trust, communication, and participation that have been at work. Moving beyond the fact that variance exists with regard to the relevant national institutional, legal, cultural, industrial, and energy frameworks, the authors take evidence from national case studies and look for common patterns.

    We report about a characterization study of a subset of large amplitude noise events present in the main data channel of the VIRGO detector. The main motivation of this study is the identification of auxiliary channels which can be used to define veto procedures. We characterized large amplitude events both in the time and in the frequency domain. We found evidence of coincidences among these and disturbances detected by magnetometer's sensors or inside the main power supply. In some cases the disturbances were produced by events in the VIRGO environment such as lightnings, main power supply glitches and airplane traffic. We have found two auxiliary channels that can be used to veto events generated by main power supply glitches or lightnings. A procedure to clean the main channel based on them has been successfully tested. We have also identified two auxiliary channels which are useful for the identification of events generated by airplane traffic. These can be used to implement a vetoing procedure both in the time and in the frequency domain.

    In this article a recently developed model [A. Palmero, H. Rudolph, and F. H. P. M. Habraken, Appl. Phys. Lett. 89, 211501 (2006)] is applied to analyze the transport of sputtered material from the cathode toward the growing film when using a plasma-assisted sputtering deposition technique. The argon pressure dependence of the deposition rate of aluminum, silicon, vanadium, chromium, germanium, tantalum, and tungsten under several different experimental conditions has been analyzed by fitting experimental results from the literature to the above-mentioned theory. Good fits are obtained. Three quantities are deduced from the fit: the temperature of the cathode and of the growing film, and the value of the effective cross section for thermalization due to elastic scattering of a sputtered particle on background gas atoms. The values derived from the fits for the growing film and cathode temperature are very similar to those experimentally determined and reported in the literature. The effective cross sections have been found to be approximately the corresponding geometrical cross section divided by the average number of collisions required for the thermalization, implying that the real and effective thermalization lengths have a similar value. Finally, the values of the throw distance appearing in the Keller-Simmons model, as well as its dependence on the deposition conditions have been understood invoking the values of the cathode and film temperature, as well as of the value of the effective cross section. The analysis shows the overall validity of this model for the transport of sputtered particles in sputter deposition

    The performance of accelerated solvent extraction in the analysis of terpenoids and sterols in tobacco samples was investigated and compared with those of Soxhlet extraction and ultrasonically assisted extraction with respect to yield, extraction time, reproducibility and solvent consumption. The results indicate that although the highest yield was achieved by Soxhlet extraction, ASE appears to be a promising alternative to classical methods since it is faster and uses less solvent, especially when applied to the investigation of large batch tobacco samples. However, Soxhlet extraction is still the preferred method for analyzing sterols since it gives a higher extraction efficiency than other methods.

    Modern medicine, specifically assisted reproductive technology (ART), has overtaken the law in many jurisdictions around the world. New technologies and practices open a Pandora's Box of ethical, religious, social and legal questions, and may present a variety of significant legal problems to the courts and legislators. Surrogate motherhood and pregnancy through ART have both attracted controversy. Some groups condemn ART and want it banned while its supporters acknowledge there is a need for legislative guidelines and regulations. A proposed statute, the Assisted Reproductive Technique Services Act, aimed at regulating reproductive technologies, including surrogacy arrangements, will be introduced in the Malaysian parliament, probably in 2012, and the Assisted Reproductive Technology (Regulation) Bill 2010 is already before the Indian parliament. This paper will discuss several of the potential socio-legal issues surrounding ART in the light of the complex situation, with a comparative analysis of the Malaysian, USA, UK and Indian positions.

  8. The Shape and Sustainability of Turkey’s Booming Humanitarian Assistance

    2014-05-01

    Full Text Available With several rising powers emerging as new actors on the humanitarian scene, viewing all ‘emerging donors’ as a homogenous group inevitably undermines efforts to constructively engage with them. With Turkey’s widely recognized engagement in Somalia and Syria, the country merits a nuanced analysis. How does it conceptualize humanitarian assistance? What norms and interests shape its humanitarian engagement? How is such an engagement financed and organized? Thoroughly evaluating how foreign and domestic agendas shape Turkey’s humanitarian engagement, the paper details how Ankara designs and implements its humanitarian assistance. The collaborative relationship between the government, faith-based businesses, and the religious segment of a generally deeply divided civil society emerges as a unique feature of Turkey’s humanitarian assistance. This set-up calls for an informed approach towards working with specific Turkish actors. It also questions the sustainability and scalability of current aid levels.

    Elderly are confronted with reduced physical capabilities and increased metabolic energy cost of walking. Exoskeletons that assist walking have the potential to restore walking capacity by reducing the metabolic cost of walking. However, it is unclear if current exoskeletons can reduce energy cost in elderly. Our goal was to study the effect of an exoskeleton that assists plantarflexion during push-off on the metabolic energy cost of walking in physically active and healthy elderly. Seven elderly (age 69.3±3.5y) walked on treadmill (1.11ms 2 ) with normal shoes and with the exoskeleton both powered (with assistance) and powered-off (without assistance). After 20min of habituation on a prior day and 5min on the test day, subjects were able to walk with the exoskeleton and assistance of the exoskeleton resulted in a reduction in metabolic cost of 12% versus walking with the exoskeleton powered-off. Walking with the exoskeleton was perceived less fatiguing for the muscles compared to normal walking. Assistance resulted in a statistically nonsignificant reduction in metabolic cost of 4% versus walking with normal shoes, likely due to the penalty of wearing the exoskeleton powered-off. Also, exoskeleton mechanical power was relatively low compared to previously identified optimal assistance magnitude in young adults. Future exoskeleton research should focus on further optimizing exoskeleton assistance for specific populations and on considerate integration of exoskeletons in rehabilitation or in daily life. As such, exoskeletons should allow people to walk longer or faster than without assistance and could result in an increase in physical activity and resulting health benefits.

It was used as a legal frame work the 1988 Federal Constitution, the Organic Law of Social Assistance– “LOAS”, updated by the law that created the “SUAS”, which regulated the social assistance as Social Security Policy, citizen's right Andres possibility of the State. In this sense, clientelistic practices preclude the exercise of citizenship displayed by those laws. The reproduction of clientelismin social assistance policy leads to discussions about the relationship between state and society in Brazil. So, at first, the text attempts to recover the historical particularity of the formation of the Brazilian state through analysis of patrimonialism. As theoretical support, it uses an interdisciplinary approach, based on concepts from the field of sociology, political science, law and the theoretical debate of social service. Secondly, it presents the importance of the 1988 Constitution in the process of social rights’ construction in Brazil and, finally, social assistance and public policy. To develop this article, we used the procedures of literature and documents research. The laws governing social assistance, information obtained from official documents and web sites related to the area indicate significant advances in social assistance in Brazil and in the state of Paraná, mainly in the bureaucratic-formal context. However, the operationalization of the policy is still highlighted in the aspects of clientelistic practices, such as the permanence of the first “ladism” in the management of social assistance in some states and municipalities.

    We develop an instantonic calculus to derive an analytical expression for the thermally assisted tunneling decay rate of a metastable state in a fully connected quantum spin model. The tunneling decay problem can be mapped onto the Kramers escape problem of a classical random dynamical field. This dynamical field is simulated efficiently by path-integral quantum Monte Carlo (QMC). We show analytically that the exponential scaling with the number of spins of the thermally assisted quantum tunneling rate and the escape rate of the QMC process are identical. We relate this effect to the existence of a dominant instantonic tunneling path. The instanton trajectory is described by nonlinear dynamical mean-field theory equations for a single-site magnetization vector, which we solve exactly. Finally, we derive scaling relations for the "spiky" barrier shape when the spin tunneling and QMC rates scale polynomially with the number of spins N while a purely classical over-the-barrier activation rate scales exponentially with N .

    Full Text Available Objective: Millennium Development Goal 5 calls for increasing proportions of deliveries assisted by skilled health personnel to reduce maternal mortality. This study aims to identifying the implication of exposure to intimate partner violence on these proportions. Methodology: This study used domestic violence modules data of Demographic and Health Surveys of six countries from 2005 to 2007. Proportions of assisted deliveries were examined by sociodemographic characteristics and exposure to intimate partner violence in the studied countries. Influence on the proportion was examined against exposure to intimate partner violence through odds ratio and 95% of logistic regression analysis after controlling for women age, residence (urban/rural, household wealth level, economic level of country, educational level and working status of women and their husbands/partners. Results: Data sets of 18,507 participants over 20 years of age showed that almost three-quarters (73% of women had deliveries assisted by skilled health personnel. One-third of the women were ever exposed to intimate partner violence (37% and 9% of them to the severe level. Exposure to intimate partner violence statistically significantly lowered this proportion to 69% (odds ratio: 0.73; 95% confidence interval: 0.67–0.78 meanwhile severe violence lowered it to 65% (odds ratio 0.64; 95% confidence interval: 0.58–0.72. When running multiple regression analysis, exposure to intimate partner violence retained its statistically significant decreasing influence on proportions and was not biased by the other stronger socioeconomic characteristics. Conclusion and recommendations: Intimate partner violence has an independent influence on reducing assisted deliveries by skilled health personnel. Programs working for increasing proportions of assisted deliveries by skilled health personnel are recommended to integrate protection women from violence.

    2018-03-01

    To describe a feasible quality improvement system to manage feeding assistance care processes in an assisted living facility (ALF) that provides dementia care and the use of these data to maintain the quality of daily care provision and prevent unintentional weight loss. Supervisory ALF staff used a standardized observational protocol to assess feeding assistance care quality during and between meals for 12 consecutive months for 53 residents receiving dementia care. Direct care staff received feedback about the quality of assistance and consistency of between-meal snack delivery for residents with low meal intake and/or weight loss. On average, 78.4% of the ALF residents consumed more than one-half of each served meal and/or received staff assistance during meals to promote consumption over the 12 months. An average of 79.7% of the residents were offered snacks between meals twice per day. The prevalence of unintentional weight loss averaged 1.3% across 12 months. A quality improvement system resulted in sustained levels of mealtime feeding assistance and between-meal snack delivery and a low prevalence of weight loss among ALF residents receiving dementia care. Given that many ALF residents receiving dementia care are likely to be at risk for low oral intake and unintentional weight loss, ALFs should implement a quality improvement system similar to that described in this project, despite the absence of regulations to do so.

    2001-04-01

    Using research methodology for analysis of secondary data, statistical data for five National Basketball Association (NBA) seasons (1993-1994 to 1997-1998) were examined to test for a relationship between team assists (a behavioral measure of teamwork) and win-loss record. Rank-difference correlation indicated a significant relationship between the two variables, the coefficients ranging from .42 to .71. Team assist totals produced higher correlations with win-loss record than assist totals for the five players receiving the most playing time ("the starters"). A comparison of "assisted team points" and "unassisted team points" in relationship to win-loss record favored the former and strongly suggested that how a basketball team scores points is more important than the number of points it scores. These findings provide circumstantial support for the popular dictum in competitive team sports that "Teamwork Means Success-Work Together, Win Together."

    Full Text Available Objective: The objective of the study was to determine whether health care aides (HCAs could safely assist in medication administration in long-term care (LTC. Method: We obtained medication error reports from LTC facilities that involve HCAs in oral medication assistance and we analyzed Resident Assessment Instrument (RAI data from these facilities. Standard ratings of error severity were “no apparent harm,” “minimum harm,” and “moderate harm.” Results: We retrieved error reports from two LTC facilities with 220 errors reported by all health care providers including HCAs. HCAs were involved in 137 (63% errors, licensed practical nurses (LPNs/registered nurses (RNs in 77 (35%, and pharmacy in four (2%. The analysis of error severity showed that HCAs were significantly less likely to cause errors of moderate severity than other nursing staff (2% vs. 7%, chi-square = 5.1, p value = .04. Conclusion: HCAs’ assistance in oral medications in LTC facilities appears to be safe when provided under the medication assistance guidelines.

    2010-06-01

    Robotic surgery has evolved over the last decade to compensate for limitations in human dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations. The nature of the robotic assistance varies from voice activated camera control to more elaborate telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a voice activated camera control system.

  2. Attachment Style Is Related to Quality of Life for Assistance Dog Owners.

    2017-06-19

    Attachment styles have been shown to affect quality of life. Growing interest in the value of companion animals highlights that owning a dog can also affect quality of life, yet little research has explored the role of the attachment bond in affecting the relationship between dog ownership and quality of life. Given that the impact of dog ownership on quality of life may be greater for assistance dog owners than pet dog owners, we explored how anxious attachment and avoidance attachment styles to an assistance dog affected owner quality of life ( n = 73). Regression analysis revealed that higher anxious attachment to the dog predicted enhanced quality of life. It is suggested that the unique, interdependent relationship between an individual and their assistance dog may mean that an anxious attachment style is not necessarily detrimental. Feelings that indicate attachment insecurity in other relationships may reflect more positive aspects of the assistance dog owner relationship, such as the level of support that the dog provides its owner.

  6. A role for doctors in assisted dying? An analysis of legal regulations and medical professional positions in six European countries.

    Bosshard, G; Broeckaert, B; Clark, D; Materstvedt, L J; Gordijn, B; Müller-Busch, H C

    2008-01-01

    To analyse legislation and medical professional positions concerning the doctor's role in assisted dying in western Europe, and to discuss their implications for doctors. This paper is based on country-specific reports by experts from European countries where assisted dying is legalised (Belgium, The Netherlands), or openly practiced (Switzerland), or where it is illegal (Germany, Norway, UK). Laws on assisted dying in The Netherlands and Belgium are restricted to doctors. In principle, assisted suicide (but not euthanasia) is not illegal in either Germany or Switzerland, but a doctor's participation in Germany would violate the code of professional medical conduct and might contravene of a doctor's legal duty to save life. The Assisted Dying for the Terminally Ill Bill proposed in the UK in 2005 focused on doctors, whereas the Proposal on Assisted Dying of the Norwegian Penal Code Commission minority in 2002 did not. Professional medical organisations in all these countries except The Netherlands maintain the position that medical assistance in dying conflicts with the basic role of doctors. However, in Belgium and Switzerland, and for a time in the UK, these organisations dropped their opposition to new legislation. Today, they regard the issue as primarily a matter for society and politics. This "neutral" stance differs from the official position of the Royal Dutch Medical Association which has played a key role in developing the Dutch practice of euthanasia as a "medical end-of-life decision" since the 1970s. A society moving towards an open approach to assisted dying should carefully identify tasks to assign exclusively to medical doctors, and distinguish those possibly better performed by other professions.

  7. Responses to assisted suicide requests: an interview study with Swiss palliative care physicians.

    Assisted suicide in Switzerland is mainly performed by right-to-die societies. Medical involvement is limited to the prescription of the drug and certification of eligibility. Palliative care has traditionally been perceived as generally opposed to assisted suicide, but little is known about palliative care physicians' involvement in assisted suicide practices. This paper aims to describe their perspectives and involvement in assisted suicide practices. A qualitative interview study was conducted with 23 palliative care physicians across Switzerland. Thematic analysis was used to interpret data. Swiss palliative care physicians regularly receive assisted suicide requests while none reported having received specific training in managing these requests. Participants reported being involved in assisted suicide decision making most were not willing to prescribe the lethal drug. After advising patients of the limits on their involvement in assisted suicide, the majority explored the origins of the patient's request and offered alternatives. Many participants struggled to reconcile their understanding of palliative care principles with patients' wishes to exercise their autonomy. The majority of participants had no direct contact with right-to-die societies, many desired better collaboration. A desire was voiced for a more structured debate on assisted suicide availability in hospitals and clearer legal and institutional frameworks. The Swiss model of assisted suicide gives palliative care physicians opportunities to develop roles which are compatible with each practitioner's values, but may not correspond to patients' expectations. Specific education for all palliative care professionals and more structured ways to manage communication about assisted suicide are warranted. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    In this paper, mesoporous tungsten titanate (WTiO) with different nano-pore structures was utilized as matrix for the analysis of short peptides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). Effect of characteristic features of mesoporous matrices on laser desorption/ionization process was investigated. Experiments showed that the ordered two-dimensional and three-dimensional mesoporous matrices were superior in performance to the non-ordered WTiO matrix. The dramatic enhancement of signal sensitivity by the ordered mesoporous matrices can be reasonably attributed to the ordered structure, which facilitated the understanding on structure-function relationship in mesoporous cavity for laser desorption process of adsorbed biomolecules. With the ordered mesoporous matrix, the short peptides are successfully detected. The presence of trace alkali metal salt effectively increased the analyte ion yields and the MALDI-TOFMS using the inorganic mesoporous matrices displayed a high salt tolerance. The developed technique also showed a satisfactory performance in peptide-mapping and amino-acid sequencing analysis

  9. Robot-assisted general surgery.

    2004-06-01

    With the initiation of laparoscopic techniques in general surgery, we have seen a significant expansion of minimally invasive techniques in the last 16 years. More recently, robotic-assisted laparoscopy has moved into the general surgeon's armamentarium to address some of the shortcomings of laparoscopic surgery. AESOP (Computer Motion, Goleta, CA) addressed the issue of visualization as a robotic camera holder. With the introduction of the ZEUS robotic surgical system (Computer Motion), the ability to remotely operate laparoscopic instruments became a reality. US Food and Drug Administration approval in July 2000 of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA) further defined the ability of a robotic-assist device to address limitations in laparoscopy. This includes a significant improvement in instrument dexterity, dampening of natural hand tremors, three-dimensional visualization, ergonomics, and camera stability. As experience with robotic technology increased and its applications to advanced laparoscopic procedures have become more understood, more procedures have been performed with robotic assistance. Numerous studies have shown equivalent or improved patient outcomes when robotic-assist devices are used. Initially, robotic-assisted laparoscopic cholecystectomy was deemed safe, and now robotics has been shown to be safe in foregut procedures, including Nissen fundoplication, Heller myotomy, gastric banding procedures, and Roux-en-Y gastric bypass. These techniques have been extrapolated to solid-organ procedures (splenectomy, adrenalectomy, and pancreatic surgery) as well as robotic-assisted laparoscopic colectomy. In this chapter, we review the evolution of robotic technology and its applications in general surgical procedures.

    2009-12-01

    Posterior rhabdosphincter (PR) reconstruction during robot-assisted radical prostatectomy (RARP) was introduced in an attempt to improve postoperative continence. In the present study, we evaluate time to achieve continence in patients who are undergoing RARP with and without PR reconstruction. A prospective RARP database was searched for most recent cases that were accomplished with PR reconstruction (group 1, n = 69) or with standard technique (group 2, n = 63). We performed the analysis applying two definitions of continence: 0 pads per day or 0-1 security pad per day. Patients were evaluated by telephone interview. Statistical analysis was carried out using the Kaplan-Meier method and log-rank test. With PR reconstruction, continence was improved when defined as 0-1 security pad per day (median time of 90 vs 150 days; P = 0.01). This difference did not achieve statistical significance when continence was defined as 0 pads per day (P = 0.12). A statistically significant improvement in continence rate and time to achieve continence is seen in patients who are undergoing PR reconstruction during RARP, with continence defined as 0-1 security/safety pad per day. A larger, prospective and randomized study is needed to better understand the impact of this technique on postoperative continence.

    2009-10-01

    By discussing the causes behind the high amendments ratio in the implementation of urban regulatory detailed plans in China despite its law-ensured status, the study aims to reconcile conflict between the legal authority of regulatory detailed planning and the insufficient scientific support in its decision-making and compilation by introducing into the process spatial analysis based on GIS technology and 3D modeling thus present a more scientific and flexible approach to regulatory detailed planning in China. The study first points out that the current compilation process of urban regulatory detailed plan in China employs mainly an empirical approach which renders it constantly subjected to amendments; the study then discusses the need and current utilization of GIS in the Chinese system and proposes the framework of a GIS-assisted 3D spatial analysis process from the designer's perspective which can be regarded as an alternating processes between the descriptive codes and physical design in the compilation of regulatory detailed planning. With a case study of the processes and results from the application of the framework, the paper concludes that the proposed framework can be an effective instrument which provides more rationality, flexibility and thus more efficiency to the compilation and decision-making process of urban regulatory detailed plan in China.

  12. Investigating walking environments in and around assisted living facilities: a facility visit study.

    2010-01-01

    This study explores assisted living residents' walking behaviors, locations where residents prefer to walk, and walking environments in and around assisted living facilities. Regular walking is beneficial to older adults' physical and psychological health. Yet frail older residents in assisted living are usually too sedentary to achieve these benefits. The physical environment plays an important role in promoting physical activity. However, there is little research exploring this relationship in assisted living settings. The researcher visited 34 assisted living facilities in a major Texas city. Methods included walk-through observation with the Assisted Living Facility Walking Environment Checklist, and interviews with administrators by open- and close-ended questions. The data from 26 facilities were analyzed using descriptive statistics (for quantitative data) and content analysis (for qualitative data). The results indicate that (a) residents were walking both indoors and outdoors for exercise or other purposes (e.g., going to destinations); (b) assisted living facility planning and design details-such as neighborhood sidewalk conditions, facility site selection, availability of seating, walking path configuration (e.g., looped/nonlooped path), amount of shading along the path, presence of handrails, existence of signage, etc.-may influence residents' walking behaviors; and (c) current assisted living facilities need improvement in all aspects to make their environments more walkable for residents. Findings of the study provide recommendations for assisted living facilities to improve the walkability of environments and to create environmental interventions to promote regular walking among their residents. This study also implies several directions for future research.

    High-throughput screening assays have become the starting point of many drug discovery programs for large pharmaceutical companies as well as academic organisations. Despite the increasing throughput of screening technologies, the almost infinite chemical space remains out of reach, calling for tools dedicated to the analysis and selection of the compound collections intended to be screened. We present Screening Assistant 2 (SA2), an open-source JAVA software dedicated to the storage and analysis of small to very large chemical libraries. SA2 stores unique molecules in a MySQL database, and encapsulates several chemoinformatics methods, among which: providers management, interactive visualisation, scaffold analysis, diverse subset creation, descriptors calculation, sub-structure / SMART search, similarity search and filtering. We illustrate the use of SA2 by analysing the composition of a database of 15 million compounds collected from 73 providers, in terms of scaffolds, frameworks, and undesired properties as defined by recently proposed HTS SMARTS filters. We also show how the software can be used to create diverse libraries based on existing ones. Screening Assistant 2 is a user-friendly, open-source software that can be used to manage collections of compounds and perform simple to advanced chemoinformatics analyses. Its modular design and growing documentation facilitate the addition of new functionalities, calling for contributions from the community. The software can be downloaded at http://sa2.sourceforge.net/.

  17. System performance and economic analysis of solar-assisted cooling/heating system

    KAUST Repository

    Huang, B.J.

    2011-11-01

    The long-term system simulation and economic analysis of solar-assisted cooling/heating system (SACH-2) was carried out in order to find an economical design. The solar heat driven ejector cooling system (ECS) is used to provide part of the cooling load to reduce the energy consumption of the air conditioner installed as the base-load cooler. A standard SACH-2 system for cooling load 3.5. kW (1. RT) and daily cooling time 10 h is used for case study. The cooling performance is assumed only in summer seasons from May to October. In winter season from November to April, only heat is supplied. Two installation locations (Taipei and Tainan) were examined.It was found from the cooling performance simulation that in order to save 50% energy of the air conditioner, the required solar collector area is 40m2 in Taipei and 31m2 in Tainan, for COPj=0.2. If the solar collector area is designed as 20m2, the solar ejector cooling system will supply about 17-26% cooling load in Taipei in summer season and about 21-27% cooling load in Tainan. Simulation for long-term performance including cooling in summer (May-October) and hot water supply in winter (November-April) was carried out to determine the monthly-average energy savings. The corresponding daily hot water supply (with 40°C temperature rise of water) for 20m2 solar collector area is 616-858L/day in Tainan and 304-533L/day in Taipei.The economic analysis shows that the payback time of SACH-2 decreases with increasing cooling capacity. The payback time is 4.8. years in Tainan and 6.2. years in Taipei when the cooling capacity >10. RT. If the ECS is treated as an additional device used as a protective equipment to avoid overheating of solar collectors and to convert the excess solar heat in summer into cooling to reduce the energy consumption of air conditioner, the payback time is less than 3 years for cooling capacity larger than 3.

    Sudra, Gunther; Speidel, Stefanie; Fritz, Dominik; Müller-Stich, Beat Peter; Gutt, Carsten; Dillmann, Rüdiger

    2007-03-01

    Minimally invasive surgery is a highly complex medical discipline with various risks for surgeon and patient, but has also numerous advantages on patient-side. The surgeon has to adapt special operation-techniques and deal with difficulties like the complex hand-eye coordination, limited field of view and restricted mobility. To alleviate with these new problems, we propose to support the surgeon's spatial cognition by using augmented reality (AR) techniques to directly visualize virtual objects in the surgical site. In order to generate an intelligent support, it is necessary to have an intraoperative assistance system that recognizes the surgical skills during the intervention and provides context-aware assistance surgeon using AR techniques. With MEDIASSIST we bundle our research activities in the field of intraoperative intelligent support and visualization. Our experimental setup consists of a stereo endoscope, an optical tracking system and a head-mounted-display for 3D visualization. The framework will be used as platform for the development and evaluation of our research in the field of skill recognition and context-aware assistance generation. This includes methods for surgical skill analysis, skill classification, context interpretation as well as assistive visualization and interaction techniques. In this paper we present the objectives of MEDIASSIST and first results in the fields of skill analysis, visualization and multi-modal interaction. In detail we present a markerless instrument tracking for surgical skill analysis as well as visualization techniques and recognition of interaction gestures in an AR environment.

    Full Text Available Sustainable crop production is the major challenge in the current global climate change scenario. Drought stress is one of the most critical abiotic factors which negatively impact crop productivity. In recent years, knowledge about molecular regulation has been generated to understand drought stress responses. For example, information obtained by transcriptome analysis has enhanced our knowledge and facilitated the identification of candidate genes which can be utilized for plant breeding. On the other hand, it becomes more and more evident that the translational and post-translational machinery plays a major role in stress adaptation, especially for immediate molecular processes during stress adaptation. Therefore, it is essential to measure protein levels and post-translational protein modifications to reveal information about stress inducible signal perception and transduction, translational activity and induced protein levels. This information cannot be revealed by genomic or transcriptomic analysis. Eventually, these processes will provide more direct insight into stress perception then genetic markers and might build a complementary basis for future marker-assisted selection of drought resistance. In this review, we survey the role of proteomic studies to illustrate their applications in crop stress adaptation analysis with respect to productivity. Cereal crops such as wheat, rice, maize, barley, sorghum and pearl millet are discussed in detail. We provide a comprehensive and comparative overview of all detected protein changes involved in drought stress in these crops and have summarized existing knowledge into a proposed scheme of drought response. Based on a recent proteome study of pearl millet under drought stress we compare our findings with wheat proteomes and another recent study which defined genetic marker in pearl millet.

    Dogs are the most common companion animal, and therefore not surprisingly a popular choice for animal-assisted interventions. Dog-assisted interventions are increasingly used in healthcare. The aim of the review was to conduct a systematic literature review of quantitative studies on dog-assisted interventions in healthcare, with the intention of assessing the effects and cost-effectiveness of the interventions for different categories of patients. A systematic review of the scientific literature reporting results of studies in healthcare, nursing home or home care settings, was conducted. The inclusion criteria applied for this review were: quantitative studies, inclusion of at least 20 study subjects, existence of a control and performed in healthcare settings including nursing homes and home care. The electronic databases PubMed, AMED, CINAHL and Scopus were searched from their inception date through January 2017, for published articles from peer-reviewed journals with full text in English. Eighteen studies that fulfilled the inclusion criteria, and were judged to be of at least moderate quality, were included in the analysis. Three of them showed no effect. Fifteen showed at least one significant positive effect but in most studied outcome measures there was no significant treatment effect. Dog-assisted therapy had the greatest potential in treatment of psychiatric disorders among both young and adult patients. Dog-assisted activities had some positive effects on health, wellbeing, depression and quality of life for patients with severe cognitive disorders. Dog-assisted support had positive effects on stress and mood. The overall assessment of the included studies indicates minor to moderate effects of dog-assisted therapy in psychiatric conditions, as well as for dog-assisted activities in cognitive disorders and for dog-assisted support in different types of medical interventions. However, the majority of studied outcome measures showed no significant effect.

  3. Assistive/Socially Assistive Robotic Platform for Therapy and Recovery: Patient Perspectives

    Full Text Available Improving adherence to therapy is a critical component of advancing outcomes and reducing the cost of rehabilitation. A robotic platform was previously developed to explore how robotics could be applied to the social dimension of rehabilitation to improve adherence. This paper aims to report on feedback given by end users of the robotic platform as well as the practical applications that socially assistive robotics could have in the daily life activities of a patient. A group of 10 former and current patients interacted with the developed robotic platform during a simulated exercise session before taking an experience-based survey. A portion of these participants later provided verbal feedback as part of a focus group on the potential utility of such a platform. Identified applications included assistance with reaching exercise goals, managing to-do lists, and supporting participation in social and recreational activities. The study participants expressed that the personality characteristics of the robotic system should be adapted to individual preferences and that the assistance provided over time should align with the progress of their recovery. The results from this study are encouraging and will be useful for further development of socially assistive robotics.

    This cross-sectional observational study examined formal caregivers' use of task-focused and social communication strategies while assisting individuals with moderate and severe Alzheimer's disease residing in a long-term care facility during a basic activity of daily living: toothbrushing. Thirteen formal caregiver-resident dyads were observed during a total of 78 separate toothbrushing sessions. All caregiver utterances occurring during the task were transcribed and coded for type of communication strategy utilizing a multidimensional observational coding scheme, which was developed a priori. Overall, the majority of residents, irrespective of disease severity, successfully completed toothbrushing with the support of caregiver assistance. Caregivers assisting residents with moderate and severe AD were found to use a variety of communication strategies, with task-focused strategies accounting for the majority of use. For the most part, the communicative strategies employed did not differ across disease severity. However, some differences were identified including the use of one proposition, paraphrased repetition, using the resident's name, and provision of full assistance, with these strategies being used more often when assisting individuals with severe AD. This study adds to the emerging literature supporting the use of specific communication strategies while assisting residents with AD during the completion of daily tasks. From reviewing this study, readers will be able to identify a variety of communication strategies, both task-focused and relational, that formal caregivers utilize while assisting residents with moderate and severe Alzheimer's disease (AD) during a basic activity of daily living. Furthermore, the reader will be able to distinguish between communication strategies that are optimal when assisting individuals with moderate AD as compared to assisting individuals with severe AD.

  5. Multimodal movement prediction - towards an individual assistance of patients.

    Directory of Open Access Journals (Sweden)

    Elsa Andrea Kirchner

    Full Text Available Assistive devices, like exoskeletons or orthoses, often make use of physiological data that allow the detection or prediction of movement onset. Movement onset can be detected at the executing site, the skeletal muscles, as by means of electromyography. Movement intention can be detected by the analysis of brain activity, recorded by, e.g., electroencephalography, or in the behavior of the subject by, e.g., eye movement analysis. These different approaches can be used depending on the kind of neuromuscular disorder, state of therapy or assistive device. In this work we conducted experiments with healthy subjects while performing self-initiated and self-paced arm movements. While other studies showed that multimodal signal analysis can improve the performance of predictions, we show that a sensible combination of electroencephalographic and electromyographic data can potentially improve the adaptability of assistive technical devices with respect to the individual demands of, e.g., early and late stages in rehabilitation therapy. In earlier stages for patients with weak muscle or motor related brain activity it is important to achieve high positive detection rates to support self-initiated movements. To detect most movement intentions from electroencephalographic or electromyographic data motivates a patient and can enhance her/his progress in rehabilitation. In a later stage for patients with stronger muscle or brain activity, reliable movement prediction is more important to encourage patients to behave more accurately and to invest more effort in the task. Further, the false detection rate needs to be reduced. We propose that both types of physiological data can be used in an and combination, where both signals must be detected to drive a movement. By this approach the behavior of the patient during later therapy can be controlled better and false positive detections, which can be very annoying for patients who are further advanced in

    2014-01-01

    The legalization of physician-assisted death in states such as Washington and Oregon has presented defining ethical issues for hospice programs because up to 90% of terminally ill patients who use the state-regulated procedure to end their lives are enrolled in hospice care. The authors recently partnered with the Washington State Hospice and Palliative Care Organization to examine the policies developed by individual hospice programs on program and staff participation in the Washington Death with Dignity Act. This article sets a national and local context for the discussion of hospice involvement in physician-assisted death, summarizes the content of hospice policies in Washington State, and presents an analysis of these findings. The study reveals meaningful differences among hospice programs about the integrity and identity of hospice and hospice care, leading to different policies, values, understandings of the medical procedure, and caregiving practices. In particular, the authors found differences 1) in the language used by hospices to refer to the Washington statute that reflect differences among national organizations, 2) the values that hospice programs draw on to support their policies, 3) dilemmas created by requests by patients for hospice staff to be present at a patient's death, and 4) five primary levels of noninvolvement and participation by hospice programs in requests from patients for physician-assisted death. This analysis concludes with a framework of questions for developing a comprehensive hospice policy on involvement in physician-assisted death and to assist national, state, local, and personal reflection.

    This paper presents a comparison between manufactured food products using conventional and ultrasound-assisted procedures. Three different foam-type products, chocolate Genoise, basic sponge cake, and chocolate mousse were prepared using both methods with subsequent evaluation of the samples using both sensory and physicochemical methods. Ultrasound-assisted preparations were considered superior according to the sensory analysis, and physicochemical data confirmed this finding. This approach of applying an emerging piece of equipment, with potential industrial application to assist food preparation, consists of a new technique that could be of great interest for the development of not only other food products created by molecular gastronomy but also for practical work carried out by students.

    Burkhardt, Sandra; La Harpe, Romano

    2012-12-01

    Assisted suicide is allowed in 3 states of the United States (Oregon, Washington, Montana) but only if performed by a physician.On the opposite, in Switzerland, at the beginning of the 20th century, the Swiss Penal Code referred to assisted suicide in the context of honor or an unhappy love affair. It was only in 1985 that Exit Deutsche Schweiz (Exit for German-speaking Switzerland) "medically" assisted the first patient to end his life.Even if authorized by the Swiss law upon certain conditions, assisted suicide is subject to debates for ethical reasons. The Swiss Academy of Medical Sciences described directives to guide physicians on this difficult subject.Different studies showed an increase in the number of medical-assisted suicide in Switzerland since the 1990s. Now, this number seems to be quite stable. Assisted suicide is authorized in a few hospitals under strict conditions (especially when returning home is impossible).Thus, according to the Swiss law, any person could perform assisted suicide; this is essentially performed by 3 main associations, using pentobarbital on medical prescription as lethal substance.Generally speaking, the Swiss population is rather in favor of assisted suicide. Among politics, the debate has been tough until 2010, when the Federal Council decided not to modify the Swiss Penal Code concerning assisted suicide.

    While robotic assisted radical nephrectomy is safe with outcomes and complication rates comparable to those of the pure laparoscopic approach, there is little evidence of an economic or clinical benefit. From the 2009 to 2011 Nationwide Inpatient Sample database we identified patients 18 years old or older who underwent radical nephrectomy for primary renal malignancy. Robotic assisted and laparoscopic techniques were noted. Patients treated with the open technique and those with evidence of metastatic disease were excluded from analysis. Descriptive statistics were performed using the chi-square and Mann-Whitney tests, and the Student t-test. Multiple linear regression was done to examine factors associated with increased hospital costs and charges. We identified 24,312 radical nephrectomy cases for study inclusion, of which 7,787 (32%) were performed robotically. There was no demographic difference between robotic assisted and pure laparoscopic radical nephrectomy cases. Median total charges were $47,036 vs $38,068 for robotic assisted vs laparoscopic surgery (p robotic assisted surgery were $15,149 compared to $11,735 for laparoscopic surgery (p robotic assistance conferred an estimated $4,565 and $11,267 increase in hospital costs and charges, respectively, when adjusted for adapted Charlson comorbidity index score, perioperative complications and length of stay (p Robotic assisted radical nephrectomy results in increased medical expense without improving patient morbidity. Assuming surgeon proficiency with pure laparoscopy, robotic technology should be reserved primarily for complex surgeries requiring reconstruction. Traditional laparoscopic techniques should continue to be used for routine radical nephrectomy. Copyright © 2014 American Urological Association Education and Research, Inc.

    This thesis primarily describes analysis related to studying the Moon shadow with cosmic rays, an analysis using upward-going muons trigger data, and other work done as part of MSc thesis work conducted at Fermi National Laboratory. While at Fermilab I made hardware and software contributions to two experiments - NOvA and Mu2e. NOvA is a neutrino experiment with the primary goal of measuring parameters related to neutrino oscillation. This is a running experiment, so it's possible to provide analysis of real beam and cosmic data. Most of this work was related to the Data-Driven Trigger (DDT) system of NOvA. The results of the Upward-Going muon analysis was presented at ICHEP in August 2016. The analysis demonstrates the proof of principle for a low-mass dark matter search. Mu2e is an experiment currently being built at Fermilab. Its primary goal is to detect the hypothetical neutrinoless conversion from a muon into an electron. I contributed to the production and tests of Cathode Strip Chambers (CSCs) which are required for testing the Cosmic Ray Veto (CRV) system for the experiment. This contribution is described in the last chapter along with a short description of the technical work provided for the DDT system of the NOvA experiment. All of the work described in this thesis will be extended by the next generation of UVA graduate students and postdocs as new data is collected by the experiment. I hope my eorts of have helped lay the foundation for many years of beautiful results from Mu2e and NOvA.

  16. Cessation of environmentally-assisted cracking in a low-alloy steel: Theoretical analysis

    International Nuclear Information System (INIS)

    Wire, G.L.

    1997-01-01

    Environmentally Assisted Cracking (EAC) can cause increases in fatigue crack growth rates of 40 to 100 times the rate in air for low alloy steels. The increased rates can lead to very large predicted crack growth. EAC is activated by a critical level of dissolved sulfides at the crack tip. Sulfide inclusions (MnS) in the steel produce corrosive sulfides in solution following exposure by a growing crack. In stagnant, low oxygen water conditions considered here, diffusion is the dominant mass transport mechanism acting to change the sulfide concentration within the crack. The average crack tip velocity is below the level required to produce the critical crack tip sulfide ion concentration required for EAC. Crack extension analyses also consider the breakthrough of large, hypothetical embedded defects with the attendant large freshly exposed sulfide inventory. Combrade et al. noted that a large inventory of undissolved metallurgical sulfides on crack flanks could trigger EAC, but did not quantify the effects. Diffusion analysis is extended herein to cover breakthrough of embedded defects with large sulfide inventories. The mass transport via diffusion is limited by the sulfide solubility. As a result, deep cracks in high sulfur steels are predicted to retain undissolved sulfides for extended but finite periods of time t diss which increase with the crack length and the metallurgical sulfide content in the steel. The analysis shows that the duration of EAC is limited to t diss providing V eac , the crack tip velocity associated with EAC is less than V In , the crack tip velocity below which EAC will not occur in an initially sulfide free crack. This condition on V eac need only be met for a short time following crack cleanup to turn off EAC. The predicted crack extension due to limited duration of EAC is a small fraction of the initial embedded defect size and would not greatly change calculated crack depths

  17. Computer-assisted estimating for the Los Alamos Scientific Laboratory

    International Nuclear Information System (INIS)

    Spooner, J.E.

    1976-02-01

    An analysis is made of the cost estimating system currently in use at the Los Alamos Scientific Laboratory (LASL) and the benefits of computer assistance are evaluated. A computer-assisted estimating system (CAE) is proposed for LASL. CAE can decrease turnaround and provide more flexible response to management requests for cost information and analyses. It can enhance value optimization at the design stage, improve cost control and change-order justification, and widen the use of cost information in the design process. CAE costs are not well defined at this time although they appear to break even with present operations. It is recommended that a CAE system description be submitted for contractor consideration and bid while LASL system development continues concurrently

    Background To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. Methods The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. Results A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Conclusions Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation. Randomized studies should compare the respective outcomes of robot-assisted, laparoscopic and open pancreatic surgery. PMID:23216773

  19. Microfluidic analysis of oocyte and embryo biomechanical properties to improve outcomes in assisted reproductive technologies.

    Yanez, Livia Z; Camarillo, David B

    2017-04-01

    Measurement of oocyte and embryo biomechanical properties has recently emerged as an exciting new approach to obtain a quantitative, objective estimate of developmental potential. However, many traditional methods for probing cell mechanical properties are time consuming, labor intensive and require expensive equipment. Microfluidic technology is currently making its way into many aspects of assisted reproductive technologies (ART), and is particularly well suited to measure embryo biomechanics due to the potential for robust, automated single-cell analysis at a low cost. This review will highlight microfluidic approaches to measure oocyte and embryo mechanics along with their ability to predict developmental potential and find practical application in the clinic. Although these new devices must be extensively validated before they can be integrated into the existing clinical workflow, they could eventually be used to constantly monitor oocyte and embryo developmental progress and enable more optimal decision making in ART. © The Author 2016.

    This study performed microwave-assisted acid pretreatment on pure lignin. The effects of microwave temperature, microwave time, and hydrochloric acid concentration on characteristics and pyrolysis behavior of lignin were examined. Results of ultimate analysis revealed better properties of all pretreated samples than those of raw lignin. Fourier transform infrared spectroscopy analysis showed breakage of βO4 bond and aliphatic side chain, decrease in OH groups, and formation of CO groups in pretreatment. Microwave temperature exerted more significant influence on lignin structure. Thermal stability of treated lignin was improved and insensitive to short microwave time and acid concentration under mild conditions. Resulting from improved alkyl-phenols and decreased alkoxy-phenols, microwave-assisted acid pretreatment of lignin yielded bio-oil with excellent quality. Total yield of phenols in pyrolysis vapors (200 °C) improved to 14.15%, whereas that of guaiacols decreased to 22.36%. This study shows that microwave-assisted acid pretreatment is a promising technology for lignin conversion. Copyright © 2017 Elsevier Ltd. All rights reserved.
