  1. Understanding survival analysis: Kaplan-Meier estimate.

    Science.gov (United States)

    Goel, Manish Kumar; Khanna, Pardeep; Kishore, Jugal

    2010-10-01

    Kaplan-Meier estimate is one of the best options to be used to measure the fraction of subjects living for a certain amount of time after treatment. In clinical trials or community trials, the effect of an intervention is assessed by measuring the number of subjects survived or saved after that intervention over a period of time. The time starting from a defined point to the occurrence of a given event, for example death is called as survival time and the analysis of group data as survival analysis. This can be affected by subjects under study that are uncooperative and refused to be remained in the study or when some of the subjects may not experience the event or death before the end of the study, although they would have experienced or died if observation continued, or we lose touch with them midway in the study. We label these situations as censored observations. The Kaplan-Meier estimate is the simplest way of computing the survival over time in spite of all these difficulties associated with subjects or situations. The survival curve can be created assuming various situations. It involves computing of probabilities of occurrence of event at a certain point of time and multiplying these successive probabilities by any earlier computed probabilities to get the final estimate. This can be calculated for two groups of subjects and also their statistical difference in the survivals. This can be used in Ayurveda research when they are comparing two drugs and looking for survival of subjects.

    International Nuclear Information System (INIS)

    Blum, T.; Kaerkkaeinen, L.

    1994-01-01

    We experiment with adding dynamical gauge field to Kaplan (defect) fermions. In the case of U(1) gauge theory we use an inhomogeneous Higgs mechanism to restrict the 3d gauge dynamics to a planar 2d defect. In our simulations the 3d theory produce the correct 2d gauge dynamics. We measure fermion propagators with dynamical gauge fields. They posses the correct chiral structure. The fermions at the boundary of the support of the gauge field (waveguide) are non-chiral, and have a mass two times heavier than the chiral modes. Moreover, these modes cannot be excited by a source at the defect; implying that they are dynamically decoupled. We have also checked that the anomaly relation is fullfilled for the case of a smooth external gauge field. (orig.)

  4. Modified Weighted Kaplan-Meier Estimator

    Directory of Open Access Journals (Sweden)

    Mohammad Shafiq

    2007-01-01

    Full Text Available In many medical studies majority of the study subjects do not reach to the event of interest during the study period. In such situations survival probabilities can be estimated for censored observation by Kaplan Meier estimator. However in case of heavy censoring these estimates are biased and over estimate the survival probabilities. For heavy censoring a new method was proposed (Bahrawar Jan, 2005 to estimate the survival probabilities by weighting the censored observations by non-censoring rate. But the main defect in this weighted method is that it gives zero weight to the last censored observation. To over come this difficulty a new weight is proposed which also gives a non-zero weight to the last censored observation.

  5. Perturbative analysis for Kaplan's lattice chiral fermions

    International Nuclear Information System (INIS)

    Aoki, S.; Hirose, H.

    1994-01-01

    Perturbation theory for lattice fermions with domain wall mass terms is developed and is applied to investigate the chiral Schwinger model formulated on the lattice by Kaplan's method. We calculate the effective action for gauge fields to one loop, and find that it contains a longitudinal component even for anomaly-free cases. From the effective action we obtain gauge anomalies and Chern-Simons currents without ambiguity. We also show that the current corresponding to the fermion number has a nonzero divergence and it flows off the wall into the extra dimension. Similar results are obtained for a proposal by Shamir, who used a constant mass term with free boundaries instead of domain walls

    Salam Malaysia! First and foremost, I want to thank all 2nd International Conference on Mechanical Engineering Research (ICMER 2013) organisers for inviting me to address and officiate this conference. This 2nd ICMER 2013 provides a platform to bring together not only researchers, postgraduate students but also industrial people. With this platform, ICMER will embark on a whole process of making new discoveries and then translating them into products and services for the marketplace and this is only made possible with people like all of you. I would like to congratulate the ICMER 2013 organisers for the achievement of collecting 208 papers for this conference. Submissions received from 17 local universities, 7 industrial companies and 9 different countries is a great achievement for UMP. I am very happy to welcome all of you from Malaysia, Iran, Turkey, Japan, India, Australia, Ireland, Saudi Arabia and Bangladesh to this conference. As one of Malaysia's Public Universities, UMP's main challenge is to remain competitive and relevant by offering high quality technical academic programmes and research activities, focusing on its niche areas. New knowledge and findings cannot be generated without any research and development (R&D) activities. These efforts will undoubtedly generate lots of interesting results and new knowledge either bring further commercialisation activities. The Malaysian government has invested a huge sum of Ringgits in R&D over the years. Therefore, UMP must produce more quality researchers and graduates to ensure Malaysia reaps the returns from these investments vice versa of progressive economic growth for the country. UMP's 2011-2015 Strategic Plan determines to strengthen and sustained its financial support by allocating research grants and industry collaboration and consultations through its business and commercial unit. On behalf of UMP, I would like to express my appreciation to all committee members of ICMER 2013 from Faculty of Mechanical

  10. About an adaptively weighted Kaplan-Meier estimate.

    Plante, Jean-François

    2009-09-01

    The minimum averaged mean squared error nonparametric adaptive weights use data from m possibly different populations to infer about one population of interest. The definition of these weights is based on the properties of the empirical distribution function. We use the Kaplan-Meier estimate to let the weights accommodate right-censored data and use them to define the weighted Kaplan-Meier estimate. The proposed estimate is smoother than the usual Kaplan-Meier estimate and converges uniformly in probability to the target distribution. Simulations show that the performances of the weighted Kaplan-Meier estimate on finite samples exceed that of the usual Kaplan-Meier estimate. A case study is also presented.

    The head of one of the world's biggest oil companies said in February that the era of oil dominating the global energy market is creaking to a close. Future energy needs will be met by a mix of fuels that are less harmful to the environment, he said, and he called for the energy and automobile industries to collaborate on solutions to reduce emissions.“We've embarked on the beginning of the last days of the age of oil,” ARCO Chairman Mike Bowlin said at a Cambridge Energy Research Associates conference in Houston, Texas, where he also described how ARCO is moving toward a new energy model. “Our challenge is not merely to survive today's low prices, but to plan for a future in which hydrocarbons are just one of a wide variety of clean fuels that will build the global economy of the 21st century”.

    Marcus Rowden, former chairman, shares his concerns for the future of the Nuclear Regulatory Commission under the new Department of Energy (DOE). He is hopeful that a constructive relationship between the two will allow nuclear development to proceed efficiently, but with the independent regulation needed to reassure public fears. He stresses the need for regional planning and licensing reform that will improve the licensing process. Risk assessments need to be made that are relative to the risks of other energy sources. Decisions on nuclear waste disposal and power plant security are national in scope and should be made by a single body which has listened to all points of view. Resignations over regulatory decisions indicate that the system is neither perfect nor monolithic, but allows dissenting voices to be heard

    We test perturbatively a recent scheme for implementing chiral fermions on the lattice, proposed by Kaplan and modified by Narayanan and Neuberger, using as our testing ground the chiral Schwinger model. The scheme is found to reproduce the desired form of the effective action, whose real part is gauge invariant and whose imaginary part gives the correct anomaly in the continuum limit, once technical problems relating to the necesary infinite extent of the extra dimension are properly addressed. The indications from this study are that the Kaplan-Narayanan-Neuberger scheme has a good chance at being a correct lattice regularization of chiral gauge theories

    The Kaplan turbine has the best theoretical efficiency chart in the total range of operation. In order to achieve these good properties, the turbine has to be adjusted optimally. In general, these settings are performed by the manufacturer of turbines during commissioning. In practice one often meets Kaplan turbines where the scenery does not correspond to the optimal control line. The author of the contribution under consideration reports on possible causes for these errors and also methods of how this scenery can be optimized cost-effectively and how to minimize power losses.

  20. Kaplan turbine tip vortex cavitation – analysis and prevention

    International Nuclear Information System (INIS)

    Motycak, L; Skotak, A; Kupcik, R

    2012-01-01

    The work is focused on one type of Kaplan turbine runner cavitation – a tip vortex cavitation. For detailed description of the tip vortex, the CFD analysis is used. On the basis of this analysis it is possible to estimate the intensity of cavitating vortex core, danger of possible blade surface and runner chamber cavitation pitting. In the paper, the ways how to avoid the pitting effect of the tip vortex are described. In order to prevent the blade surface against pitting, the following possibilities as the change of geometry of the runner blade, dimension of tip clearance and finally the installation of the anti-cavitation lips are discussed. The knowledge of the shape and intensity of the tip vortex helps to design the anti-cavitation lips more sophistically. After all, the results of the model tests of the Kaplan runner with or without anti-cavitation lips and the results of the CFD analysis are compared.

    In this paper, the flow field considering the hub clearance flow in a Kaplan turbine has been investigated through using the commercial CFD code ANSYS CFX based on high-quality structured grids generated by ANSYS ICEM CFD. The turbulence is simulated by k-ω based shear stress transport (SST) turbulence model together with automatic near wall treatments. Four kinds of simulations have been conducted for the runner geometry without hub clearance, with only the hub front clearance, with only the rear hub clearance, and with both front and rear clearance. The analysis of the obtained results is focused on the flow structure of the hub clearance flow, the effect on the turbine performance including hydraulic efficiency and cavitation performance, which can improve the understanding on the flow field in a Kaplan turbine.

After all, the results of the model tests of the Kaplan runner with or without anti-cavitation lips and the results of the CFD analysis are compared.

    In this paper, the flow field considering the hub clearance flow in a Kaplan turbine has been investigated through using the commercial CFD code ANSYS CFX based on high-quality structured grids generated by ANSYS ICEM CFD. The turbulence is simulated by k-ω based shear stress transport (SST) turbulence model together with automatic near wall treatments. Four kinds of simulations have been conducted for the runner geometry without hub clearance, with only the hub front clearance, with only the rear hub clearance, and with both front and rear clearance. The analysis of the obtained results is focused on the flow structure of the hub clearance flow, the effect on the turbine performance including hydraulic efficiency and cavitation performance, which can improve the understanding on the flow field in a Kaplan turbine.

    Being inspired by Kaplan's proposal for simulating chiral fermions on a lattice, we examine the continuum analogue of his domain-wall construction for two-dimensional chiral Schwinger models. Adopting a slightly unusual dimensional regularization, we explicitly evaluate the one-loop effective action in the limit that the domain-wall mass goes to infinity. For anomaly-free cases, the effective action turns out to be gauge invariant in the two-dimensional sense

    2013-02-01

    A Kaplan turbine runner oscillating in turbine waterways is subjected to a varying hydrodynamic load. Numerical simulation of the related unsteady flow is time-consuming and research is very limited. In this study, a simplified method based on unsteady airfoil theory is presented for evaluation of the unsteady load for vibration analyses of the turbine shaft line. The runner is assumed to oscillate as a rigid body in spin and axial heave, and the reaction force is resolved into added masses and dampings. The method is applied on three Kaplan runners at nominal operating conditions. Estimates for added masses and dampings are considered to be of a magnitude significant for shaft line vibration. Moderate variation in the added masses and minor variation in the added dampings is found in the frequency range of interest. Reference results for added masses are derived by solving the boundary value problem for small motions of inviscid fluid using the finite element method. Good correspondence is found in the added mass estimates of the two methods. The unsteady airfoil method is considered accurate enough for design purposes. Experimental results are needed for validation of unsteady load analyses.

    Air injection is a very well-known resource to reduce pressure pulsation magnitude in turbines, especially on Francis type. In the case of large Kaplan designs, even when not so usual, it could be a solution to mitigate vibrations arising when tip vortex cavitation phenomenon becomes erosive and induces structural vibrations. In order to study this alternative, aeration tests were performed on a Kaplan turbine at model and prototype scales. The research was focused on efficiency of different air flow rates injected in reducing vibrations, especially at the draft tube and the discharge ring and also in the efficiency drop magnitude. It was found that results on both scales presents the same trend in particular for vibration levels at the discharge ring. The efficiency drop was overestimated on model tests while on prototype were less than 0.2 % for all power output. On prototype, air has a beneficial effect in reducing pressure fluctuations up to 0.2 ‰ of air flow rate. On model high speed image computing helped to quantify the volume of tip vortex cavitation that is strongly correlated with the vibration level. The hydrophone measurements did not capture the cavitation intensity when air is injected, however on prototype, it was detected by a sonometer installed at the draft tube access gallery.

  14. Interview with Pennsylvania PUC chairman Susan M. Shanaman

    1981-01-01

    Chairman Shanaman notes that Pennsylvania law justifies the Public Utility Commission (PUC) refusal to charge ratepayers for the cost of Three Mile Island units 1 and 2, neither of which are providing service, because ratepayers are already paying the costs of replacement power. The PUC chairman points to other service territories around the country where rates are kept below national averages because the average income level is low. The Metropolitan Edison Company is seeking Federal relief as well as legislative permission to put TMI-1 back into the rate base in fairness to ratepayers, but the PUC does not see bankruptcy for the utility as an appropriate way to force Federal assistance. The Administration needs to understand the local impact of Federal policies, especially those which are incompatible with state situations. Appropriate involvement includes nuclear waste research and underwriting some of the cleanup costs of onsite accidents that are too large for a single utility to handle. Chairman Shanaman feels that ratepayers should contribute to the insurance premium for future accidents, but not retroactively to support TMI-2. Nuclear power plant construction in the US will not progress until the issues of TMI-2 are resolved

  15. Numerical investigation of tip clearance cavitation in Kaplan runners

    2016-11-01

    There is a gap between the Kaplan runner blade and the shroud that makes for a special kind of cavitation: cavitation in the tip leakage flow. Two types of cavitation caused by the presence of clearance gap are known: tip vortex cavitation that appears at the core of the rolled up vortex on the blade suction side and tip clearance cavitation that appears precisely in the gap between the blade tip edge and the shroud. In the context of this work numerical investigation of the model Kaplan runner has been performed taking into account variable tip clearance for several cavitation regimes. The focus is put on investigation of structure and origination of mechanism of cavitation in the tip leakage flow. Calculations have been performed with the help of 3-D unsteady numerical model for two-phase medium. Modeling of turbulent flow in this work has been carried out using full equations of Navier-Stokes averaged by Reynolds with correction for streamline curvature and system rotation. For description of this medium (liquid-vapor) simplification of Euler approach is used; it is based on the model of interpenetrating continuums, within the bounds of this two- phase medium considered as a quasi-homogeneous mixture with the common velocity field and continuous distribution of density for both phases. As a result, engineering techniques for calculation of cavitation conditioned by existence of tip clearance in model turbine runner have been developed. The detailed visualization of the flow was carried out and vortex structure on the suction side of the blade was reproduced. The range of frequency with maximum value of pulsation was assigned and maximum energy frequency was defined; it is based on spectral analysis of the obtained data. Comparison between numerical computation results and experimental data has been also performed. The location of cavitation zone has a good agreement with experiment for all analyzed regimes.

    Science.gov (United States)

    Gröger, Maik; Hunt, Brian R.

    2013-09-01

    The Kaplan-Yorke conjecture states that for ‘typical’ dynamical systems with a physical measure, the information dimension and the Lyapunov dimension coincide. We explore this conjecture in a neighborhood of a system for which the two dimensions do not coincide because the system consists of two uncoupled subsystems. We are interested in whether coupling ‘typically’ restores the equality of the dimensions. The particular subsystems we consider are skinny baker's maps, and we consider uni-directional coupling. For coupling in one of the possible directions, we prove that the dimensions coincide for a prevalent set of coupling functions, but for coupling in the other direction we show that the dimensions remain unequal for all coupling functions. We conjecture that the dimensions prevalently coincide for bi-directional coupling. On the other hand, we conjecture that the phenomenon we observe for a particular class of systems with uni-directional coupling, where the information and Lyapunov dimensions differ robustly, occurs more generally for many classes of uni-directionally coupled systems (also called skew-product systems) in higher dimensions.

    Pressure pulsation phenomena in a large Kaplan turbine are investigated by means of numerical simulations (CFD) and prototype measurements in order to study the dynamic behavior of flow due to the blade passage and its interaction with other components of the turbine. Numerical simulations are performed with the commercial software Ansys CFX code, solving the incompressible Unsteady Reynolds-Averaged-Navier Stokes equations under a finite volume scheme. The computational domain involves the entire machine at prototype scale. Special care is taken in the discretization of the wicket gate overhang and runner blade gap. Prototype measurements are performed using pressure transducers at different locations among the wicket gate outlet and the draft tube inlet. Then, CFD results are compared with temporary signals of prototype measurements at identical locations to validate the numerical model. A detailed analysis was focused on the tip gap flow and the pressure field at the discharge ring. From a rotating reference frame perspective, it is found that the mean pressure fluctuates accordingly the wicket gate passage. Moreover, in prototype measurements the pressure frequency that reveals the presence of modulated cavitation at the discharge ring is distinguished, as also verified from the shape of erosion patches in concordance with the number of wicket gates.

    Recently, Grabowska and Kaplan [Phys. Rev. Lett. 116, 211602 (2016); Phys. Rev. D 94, 114504 (2016)] suggested a nonperturbative formulation of a chiral gauge theory, which consists of the conventional domain-wall fermion and a gauge field that evolves by gradient flow from one domain wall to the other. We introduce two sets of domain-wall fermions belonging to complex conjugate representations so that the effective theory is a 4D vector-like gauge theory. Then, as a natural definition of the axial-vector current, we consider a current that generates simultaneous phase transformations for the massless modes in 4 dimensions. However, this current is exactly conserved and does not reproduce the correct anomaly. In order to investigate this point precisely, we consider the mechanism of the conservation. We find that this current includes not only the axial current on the domain wall but also a contribution from the bulk, which is nonlocal in the sense of 4D fields. Therefore, the local current is obtained by subtracting the bulk contribution from it.

    Ukonsaari; Jan

    2012-08-15

    This study concerns environmentally adapted Kaplan runners, which have no oil for lubricating the blade regulation mechanisms and bearings. The runners are water or air filled with self lubricated bearings. Recent design also includes regulation system pressure increase and servo motor placement below runner centre and environmentally adapted synthetic ester as hydraulic fluid. These together with power output increase and efficiency optimization are suspected sources of poor runner function. Of 37 runners 43 % have had some kind of problem and 30 % bearing or mechanism related ones. When the axial blade bearing problems are excluded the problems occurred at 16 %. Deeper look into the design of newer runners shows that only bronze based runner hubs is significantly more problem dense regarding regulation mechanisms (50 %). Hidden figures of increased runner regulation forces are suspected. All problems cannot be explained and the young machines limit the experiences. The working group's opinion and bring ups of historical and present examples during the work show evidence that the old oil filled runners function is far from perfect, nor the life length. The future is not with oil filled runner hubs. Main parts of the discovered problems have been solved and can be resolved by thorough design analysis. One future concern is what effects the recent design changes will cause due to increase demand for power output changes including the number of starts and stops. That is why the working group's recommendation is to put joint effort into material fatigue and in which a first step is to identify the real forces the runners are exposed to.

    The runaway transient is a typical transient process of a hydro power unit, where the rotational speed of a turbine runner rapidly increases up to the runaway speed under a working head as the guide vanes cannot be closed due to some reason at the load rejection. In the present paper, the characteristics of the runaway transient of a model Kaplan turbine having ns = 479(m-kW) is simulated by using a time-dependent CFD technique where equation of rotational motion of runner, continuity equation and unsteady RANS equations with RNG k-{epsilon} turbulence model are solved iteratively. In the calculation, unstructured mesh is used to the whole flow passage, which consists of several sub-domains: entrance, casing, stay vanes + guide vanes, guide section, runner and draft tube. And variable speed sliding mesh technique is used to exchange interface flow information between moving part and stationary part, and three-dimensional unstructured dynamic mesh technique is also adopted to ensure mesh quality. Two cases were treated in the simulation of runaway transient characteristics after load rejection: one is the rated operating condition as the initial condition, and the other is the condition at the maximum head. Regarding the runaway speed, the experimental speed is 1.45 times the initial speed and the calculation is 1.47 times the initial for the former case. In the latter case, the experiment and the calculation are 1.67 times and 1.69 times respectively. From these results, it is recognized that satisfactorily prediction will be possible by using the present numerical method. Further, numerical results show that the swirl in the draft-tube flow becomes stronger in the latter part of the transient process so that a vortex rope will occur in the draft tube and its precession will cause the pressure fluctuations which sometimes affect the stability of hydro power system considerably.

    Nearly every day it seems that Enron Corp. adds still another project to its already far-flung energy portfolio, be it a pipeline in Argentina, LNG in Oman, or power plants in Poland, Mozambique, the Philippines, Vietnam and India. Divided into five divisions, Enron Oil and Gas Co., (EOG), Enron International (EI), Enron Capital and Trade Resources Corp. (ECT), enron Ventures Corp. (EVC), and Enron Gas Pipeline Group (GPG), it's GPC that is the nerve center of the multi-billion-dollar natural gas/electricity empire. Pipeline and Gas Journal examines GPG as part of a series beginning with a wide-ranging interview with Stanley C. Horton, chairman and CEO of Enron GPG, who discusses corporate strategy including the pipeline construction market and the unprecedented restructuring that will forever change the way industry does business

  14. Dynamic Model of Kaplan Turbine Regulating System Suitable for Power System Analysis

    Full Text Available Accurate modeling of Kaplan turbine regulating system is of great significance for grid security and stability analysis. In this paper, Kaplan turbine regulating system model is divided into the governor system model, the blade control system model, and the turbine and water diversion system model. The Kaplan turbine has its particularity, and the on-cam relationship between the wicket gate opening and the runner blade angle under a certain water head on the whole range was obtained by high-order curve fitting method. Progressively the linearized Kaplan turbine model, improved ideal Kaplan turbine model, and nonlinear Kaplan turbine model were developed. The nonlinear Kaplan turbine model considered the correction function of the blade angle on the turbine power, thereby improving the model simulation accuracy. The model parameters were calculated or obtained by the improved particle swarm optimization (IPSO algorithm. For the blade control system model, the default blade servomotor time constant given by value of one simplified the modeling and experimental work. Further studies combined with measured test data verified the established model accuracy and laid a foundation for further research into the influence of Kaplan turbine connecting to the grid.

    The paper presents a novel mathematical model for a-priori computation of the swirling flow at Kaplan runners outlet. The model is an extension of the initial version developed by Susan-Resiga et al [1], to include the contributions of non-negligible radial velocity and of the variable rothalpy. Simple analytical expressions are derived for these additional data from three-dimensional numerical simulations of the Kaplan turbine. The final results, i.e. velocity components profiles, are validated against experimental data at two operating points, with the same Kaplan runner blades opening, but variable discharge.

    Utility executives may have slowed their merger and acquisition activity to catch their breath, but it's far from over, says Jim Hoecker, the new chairman of the Federal Energy Regulatory Commission. He doesn't think we've seen the last of this phenomenon. As the industry begins to understand the shape of market developments to come in the future, increasingly creative M and A activities will be seen. But there's also many other contractual arrangements among utilities and between utilities, pipelines, and gas distribution companies that reflect the more dynamic market of today. In the interview, he referred to a survey of utility executives in which as many as 45% indicated that their companies were involved in merger or acquisition activity. That survey found about 70% of these executives felt there is going to be more consolidation within the utility industry and an even larger proportion concluded there would be increased mergers between the electric and natural gas industries. In addition, Hoecker discusses gas versus electric, gas versus coal, and FERC's future

    2016-01-01

    Risk estimates from Kaplan-Meier curves are well known to medical researchers, reviewers, and editors. In this study, we determined the proportion of Kaplan-Meier analyses published in prominent medical journals that are potentially biased because of competing events ("competing risk bias"). We randomly selected 100 studies that had at least one Kaplan-Meier analysis and were recently published in prominent medical journals. Susceptibility to competing risk bias was determined by examining the outcome and potential competing events. In susceptible studies, bias was quantified using a previously validated prediction model when the number of outcomes and competing events were given. Forty-six studies (46%) contained Kaplan-Meier analyses susceptible to competing risk bias. Sixteen studies (34.8%) susceptible to competing risk cited the number of outcomes and competing events; in six of these studies (6/16, 37.5%), the outcome risk from the Kaplan-Meier estimate (relative to the true risk) was biased upward by 10% or more. Almost half of Kaplan-Meier analyses published in medical journals are susceptible to competing risk bias and may overestimate event risk. This bias was found to be quantitatively important in a third of such studies. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The paper present an analytical analyzes refer to influence of working environment on life time duration in service of runner blades of Kaplan turbines. The study are made using only analytical method, the entry dates being obtained from measurements made in situ for a Kaplan turbine. To calculate the maximum number of stress cycles whereupon the runner blades work without any damage it was used an analytical relation known in specialized literatures under the name of Morrow’s relation. To estimate fatigue life time duration will be used a formula obtained from one of most common cumulative damage methodology taking in consideration the real exploitation conditions of a specified Kaplan turbine.

  12. Verification of Kaplan turbine cam curves realization accuracy at power plant

    2016-01-01

    Full Text Available Sustainability of approximately constant value of Kaplan turbine efficiency, for relatively large net head changes, is a result of turbine runner variable geometry. Dependence of runner blades position change on guide vane opening represents the turbine cam curve. The cam curve realization accuracy is of great importance for the efficient and proper exploitation of turbines and consequently complete units. Due to the reasons mentioned above, special attention has been given to the tests designed for cam curves verification. The goal of this paper is to provide the description of the methodology and the results of the tests performed in the process of Kaplan turbine cam curves verification.

  13. Kaplan-Meier Survival Analysis Overestimates the Risk of Revision Arthroplasty: A Meta-analysis.

    2015-11-01

    Although Kaplan-Meier survival analysis is commonly used to estimate the cumulative incidence of revision after joint arthroplasty, it theoretically overestimates the risk of revision in the presence of competing risks (such as death). Because the magnitude of overestimation is not well documented, the potential associated impact on clinical and policy decision-making remains unknown. We performed a meta-analysis to answer the following questions: (1) To what extent does the Kaplan-Meier method overestimate the cumulative incidence of revision after joint replacement compared with alternative competing-risks methods? (2) Is the extent of overestimation influenced by followup time or rate of competing risks? We searched Ovid MEDLINE, EMBASE, BIOSIS Previews, and Web of Science (1946, 1980, 1980, and 1899, respectively, to October 26, 2013) and included article bibliographies for studies comparing estimated cumulative incidence of revision after hip or knee arthroplasty obtained using both Kaplan-Meier and competing-risks methods. We excluded conference abstracts, unpublished studies, or studies using simulated data sets. Two reviewers independently extracted data and evaluated the quality of reporting of the included studies. Among 1160 abstracts identified, six studies were included in our meta-analysis. The principal reason for the steep attrition (1160 to six) was that the initial search was for studies in any clinical area that compared the cumulative incidence estimated using the Kaplan-Meier versus competing-risks methods for any event (not just the cumulative incidence of hip or knee revision); we did this to minimize the likelihood of missing any relevant studies. We calculated risk ratios (RRs) comparing the cumulative incidence estimated using the Kaplan-Meier method with the competing-risks method for each study and used DerSimonian and Laird random effects models to pool these RRs. Heterogeneity was explored using stratified meta-analyses and

    The understanding and accurate prediction of the flow behaviour related to cavitation and pressure fluctuation in a Kaplan turbine are important to the design work enhancing the turbine performance including the elongation of the operation life span and the improvement of turbine efficiency. In this paper, high accuracy turbine and cavitation performance prediction method based on entire flow passage for a Kaplan turbine is presented and evaluated. Two-phase flow field is predicted by solving Reynolds-Averaged Navier-Stokes equations expressed by volume of fluid method tracking the free surface and combined with Reynolds Stress model. The growth and collapse of cavitation bubbles are modelled by the modified Rayleigh-Plesset equation. The prediction accuracy is evaluated by comparing with the model test results of Ns 400 Kaplan model turbine. As a result that the experimentally measured data including turbine efficiency, cavitation performance, and pressure fluctuation are accurately predicted. Furthermore, the cavitation occurrence on the runner blade surface and the influence to the hydraulic loss of the flow passage are discussed. Evaluated prediction method for the turbine flow and performance is introduced to facilitate the future design and research works on Kaplan type turbine.

    Automatic runner shape optimization based on extensive CFD analysis proved to be a useful design tool in hydraulic turbomachinery. Previously the authors developed an efficient method for Francis runner optimization. It was successfully applied to the design of several runners with different specific speeds. In present work this method is extended to the task of a Kaplan runner optimization. Despite of relatively simpler blade shape, Kaplan turbines have several features, complicating the optimization problem. First, Kaplan turbines normally operate in a wide range of discharges, thus CFD analysis of each variant of the runner should be carried out for several operation points. Next, due to a high specific speed, draft tube losses have a great impact on the overall turbine efficiency, and thus should be accurately evaluated. Then, the flow in blade tip and hub clearances significantly affects the velocity profile behind the runner and draft tube behavior. All these features are accounted in the present optimization technique. Parameterization of runner blade surface using 24 geometrical parameters is described in details. For each variant of runner geometry steady state three-dimensional turbulent flow computations are carried out in the domain, including wicket gate, runner, draft tube, blade tip and hub clearances. The objectives are maximization of efficiency in best efficiency and high discharge operation points, with simultaneous minimization of cavitation area on the suction side of the blade. Multiobjective genetic algorithm is used for the solution of optimization problem, requiring the analysis of several thousands of runner variants. The method is applied to optimization of runner shape for several Kaplan turbines with different heads

    The sediment concentration in many rivers in our world is very high, and the Kaplan turbine running in these rivers are usually seriously abraded. Since the existence of sand, the probability of cavitation is greatly enhanced. Under the joint action and mutual promotion of cavitation and sand erosion, serious abrasion could be made, the hydraulic performance of the Kaplan turbine may be descended, and the safety and stability of turbine are greatly threatened. Therefore, it is very important and significant to investigate the cavitation characteristic of Kaplan turbine under sediment flow condition. In this paper, numerical simulation of cavitation characteristic in pure water and solid-liquid two-phase flow in Kaplan turbine was performed. The solid-liquid two-fluid model were adopted in the numerical simulation, and the pressure, velocity and particle concentration distributive regularity on turbine blade surface under different diameter and concentration was revealed. Particle trajectory model was used to investigate the region and degree of runner blade abrasion in different conditions. The results showed that serious sand abrasion could be found near the blade head and outlet in large flow rate working condition. Relatively slight abrasion may be found near blade flange in small flow rate working condition. The more the sediment concentration and the large the sand diameter, the serious the runner is abraded, and the greater the efficiency is decreased. further analysis of the combined effects of wear and abrasion was performed. The result shows that the cavitation in silt flow is more serious than in pure water. The runner cavitation performance become worse under high sand concentration and large particle diameter, and the efficiency decrease greatly with the increase of sediment concentration.

    Automatic runner shape optimization based on extensive CFD analysis proved to be a useful design tool in hydraulic turbomachinery. Previously the authors developed an efficient method for Francis runner optimization. It was successfully applied to the design of several runners with different specific speeds. In present work this method is extended to the task of a Kaplan runner optimization. Despite of relatively simpler blade shape, Kaplan turbines have several features, complicating the optimization problem. First, Kaplan turbines normally operate in a wide range of discharges, thus CFD analysis of each variant of the runner should be carried out for several operation points. Next, due to a high specific speed, draft tube losses have a great impact on the overall turbine efficiency, and thus should be accurately evaluated. Then, the flow in blade tip and hub clearances significantly affects the velocity profile behind the runner and draft tube behavior. All these features are accounted in the present optimization technique. Parameterization of runner blade surface using 24 geometrical parameters is described in details. For each variant of runner geometry steady state three-dimensional turbulent flow computations are carried out in the domain, including wicket gate, runner, draft tube, blade tip and hub clearances. The objectives are maximization of efficiency in best efficiency and high discharge operation points, with simultaneous minimization of cavitation area on the suction side of the blade. Multiobjective genetic algorithm is used for the solution of optimization problem, requiring the analysis of several thousands of runner variants. The method is applied to optimization of runner shape for several Kaplan turbines with different heads.

    The aim of this study was to compare the complete visible surface area of the radial head, neck, and coronoid in the Kaplan and Kocher approaches to the lateral elbow. The hypothesis was that the Kaplan approach would afford greater visibility due to the differential anatomy of the intermuscular planes. Ten cadavers were dissected with the Kaplan and Kocher approaches, and the visible surface area was measured in situ using a 3-dimensional digitizer. Six measurements were taken for each approach by 2 surgeons, and the mean of these measurements were analyzed. The mean surface area visible with the lateral collateral ligament (LCL) preserved in the Kaplan approach was 616.6 mm 2 in comparison with the surface area of 136.2 mm 2 visible in the Kocher approach when the LCL was preserved. Using a 2-way analysis of variance, the difference between these 2 approaches was statistically significant. When the LCL complex was incised in the Kocher approach, the average visible surface area of the Kocher approach was 456.1 mm 2 and was statistically less than the Kaplan approach. The average surface area of the coronoid visible using a proximally extended Kaplan approach was 197.8 mm 2 . The Kaplan approach affords significantly greater visible surface area of the proximal radius than the Kocher approach.

    How deep plant roots go and why may hold the answer to several questions regarding the co-evolution of terrestrial life and its environment. In this talk we explore how plant rooting depth responds to the hydrologic plumbing system in the soil/regolith/bedrocks, and vice versa. Through analyzing 2200 root observations of >1000 species along biotic (life form, genus) and abiotic (precipitation, soil, drainage) gradients, we found strong sensitivities of rooting depth to local soil water profiles determined by precipitation infiltration depth from the top (reflecting climate and soil), and groundwater table depth from below (reflecting topography-driven land drainage). In well-drained uplands, rooting depth follows infiltration depth; in waterlogged lowlands, roots stay shallow avoiding oxygen stress below the water table; in between, high productivity and drought can send roots many meters down to groundwater capillary fringe. We explore the global significance of this framework using an inverse model, and the implications to the coevolution of deep roots and the CZ in the Early-Mid Devonian when plants colonized the upland environments.

    The third molar teeth (wisdom teeth) represent the last eruption of the teeth in the human dentition. Throughout evolution, the mandible has had a tendency to decrease in size; the third molar teeth are often impacted, resulting in incomplete tooth eruption that often causes clinical pericoronitis, dental caries, and pericemental abscess. Therefore, the wisdom teeth are often extracted. Moreover, wisdom teeth are often removed for clinical orthodontic treatment. On the other hand, tooth loss due to periodontal disease, dental caries, trauma, or a variety of genetic disorders continues to affect people's lives. Autologous tissues for dental tissue regeneration that could replace lost teeth could provide a vital alternative to currently available clinical treatments. To pursue this goal, we hypothesize that human third molar tooth buds can be obtained during development. Human wisdom tooth germination tissue could then be placed into an embryonic stem cell bank for storage. When the donor's other teeth are missing, embryonic stem cell and tissue engineering technologies, will permit the restoration of the missing teeth. Therefore wisdom teeth will be mankind's future third vice-teeth.

    Manufacturing optical components relies on good measurements and specifications. One of the most precise measurements routinely required is the form accuracy. In practice, form deviation from the ideal surface is effectively low frequency errors, where the form error most often accounts for no more than a few undulations across a surface. These types of errors are measured in a variety of ways including interferometry and tactile methods like profilometry, with the latter often being employed for aspheres and general surface shapes such as freeforms. This paper provides a basis for a correct description of power and radius of curvature tolerances, including best practices and calculating the power value with respect to the radius deviation (and vice versa) of the surface form. A consistent definition of the sagitta is presented, along with different cases in manufacturing that are of interest to fabricators and designers. The results make clear how the definitions and results should be documented, for all measurement setups. Relationships between power and radius of curvature are shown that allow specifying the preferred metric based on final accuracy and measurement method. Results shown include all necessary equations for conversion to give optical designers and manufacturers a consistent and robust basis for decision-making. The paper also gives guidance on preferred methods for different scenarios for surface types, accuracy required, and metrology methods employed.

    This paper examines statistical issues associated with estimating paths of juvenile salmon through the intakes of Kaplan turbines. Passive sensors, hydrophones, detecting signals from ultrasonic transmitters implanted in individual fish released into the preturbine region were used to obtain the information to estimate fish paths through the intake. Aim and location of the sensors affects the spatial region in which the transmitters can be detected, and formulas relating this region to sensor aiming directions are derived. Cramer-Rao lower bounds for the variance of estimators of fish location are used to optimize placement of each sensor. Finally, a statistical methodology is developed for analyzing angular data collected from optimally placed sensors.

    This introduction to my journal of 1961--1971, covering my years of service as Chairman of the US Atomic Energy Commission, is written from the perspective of 1971, in order to reflect the attitudes expressed in my journal, which was written on a daily basis during that period. Thus, I express the points of view of that time rather than those of today (1988), which might occasionally be somewhat different. The journal consists of 25 volumes, averaging 700 pages each. This comprises about 15,000 items consisting of the approximately 4000 daily entries and the average of about three attachments per day. The journal has three sections corresponding to each of the three presidents I served as chairman of the Atomic Energy Commission -- the first six volumes covering the John F. Kennedy years (February 1, 1961--November 22, 1963), the next 11 volumes covering the Lyndon B. Johnson years (November 22, 1963--January 20, 1969) and the final eight volumes, the Richard M. Nixon years and a few months of post-AEC chairman activities in Washington (January 20, 1969--November 6, 1971.)

    Full Text Available The debate over the vice-presidents’ authority reappeared in the administration of President Jokowi after the “authority expansion of the Chief of Presidency Staff” and the case of “Rizal Ramli vs Jusuf Kalla”. This article is intended to provide arguments for the idea of some parties to organize more explicit and detailed the authority of vice-president in the 1945 Constitution. The idea arises from the absence of further arrangement on the authority of vice-president in the 1945 Constitution. This article is systematized into 3 (three sub-theme; 1 the arrangement of the vice-presidents’ authority in the constitution for several countries; 2 The authority of the vice-president according to the 1945 Constitution, and 3 New resultant and the possibility of 1945 Constitution amendment. The result revealed a number of interesting things; 1 the constitutions of other countries do not specify the authority of the vice-president and put the vice-president as a “spare tire” when the president is absent; 2 no new resultant about the position and authority of the vice-president so that theoretically is not reason enough to regulate in detail the authority of the vice-president through the 1945 Constitution amendment; 3 arrangement in detail in the authority of vice-president in the 1945 Constitution holds the potential to confuse the presidential system design as the 1945 Constitution. Therefore, the possibility of vice-presidents’ authority arrangement in the 1945 Constitution through amendment is very small, both in terms of momentum and the substance of issues.

    The present work compares simulations made using the OpenFOAM CFD code with experimental measurements of the flow in the U9 Kaplan turbine model. Comparisons of the velocity profiles in the spiral casing and in the draft tube are presented. The U9 Kaplan turbine prototype located in Porjus and its model, located in Älvkarleby, Sweden, have curved inlet pipes that lead the flow to the spiral casing. Nowadays, this curved pipe and its effect on the flow in the turbine is not taken into account when numerical simulations are performed at design stage. To study the impact of the inlet pipe curvature on the flow in the turbine, and to get a better overview of the flow of the whole system, measurements were made on the 1:3.1 model of the U9 turbine. Previously published measurements were taken at the inlet of the spiral casing and just before the guide vanes, using the laser Doppler anemometry (LDA) technique. In the draft tube, a number of velocity profiles were measured using the LDA techniques. The present work extends the experimental investigation with a horizontal section at the inlet of the draft tube. The experimental results are used to specify the inlet boundary condition for the numerical simulations in the draft tube, and to validate the computational results in both the spiral casing and the draft tube. The numerical simulations were realized using the standard k-e model and a block-structured hexahedral wall function mesh.

    2015-08-01

    Hydraulic instabilities represent a critical problem for Francis and Kaplan turbines, reducing their useful life due to increase of fatigue on the components and cavitation phenomena. Whereas an exhaustive list of publications on computational fluid-dynamic models of hydraulic instability is available, the possibility of applying diagnostic techniques based on vibration measurements has not been investigated sufficiently, also because the appropriate sensors seldom equip hydro turbine units. The aim of this study is to fill this knowledge gap and to exploit fully, for this purpose, the potentiality of combining cyclostationary analysis tools, able to describe complex dynamics such as those of fluid-structure interactions, with order tracking procedures, allowing domain transformations and consequently the separation of synchronous and non-synchronous components. This paper will focus on experimental data obtained on a full-scale Kaplan turbine unit, operating in a real power plant, tackling the issues of adapting such diagnostic tools for the analysis of hydraulic instabilities and proposing techniques and methodologies for a highly automated condition monitoring system.

    The Reynolds-averaged Navier-Stokes equations with the RNG k-ε turbulence model closure are utilized to simulate the unsteady turbulent flow throughout the whole flow passage of the U9 Kaplan turbine model. The U9 Kaplan turbine model comprises 20 stationary guide vanes and 6 rotating blades (696.3 RPM), working at best efficiency load (0.71 m3/s). The computations are conducted using a general finite volume method, using the OpenFOAM CFD code. A dynamic mesh is used together with a sliding GGI interface to include the effect of the rotating runner. The clearance is included in the guide vane. The hub and tip clearances are also included in the runner. An analysis is conducted of the unsteady behavior of the flow field, the pressure fluctuation in the draft tube, and the coherent structures of the flow. The tangential and axial velocity distributions at three sections in the draft tube are compared against LDV measurements. The numerical result is in reasonable agreement with the experimental data, and the important flow physics close to the hub in the draft tube is captured. The hub and tip vortices and an on-axis forced vortex are captured. The numerical results show that the frequency of the forced vortex in 1/5 of the runner rotation.

    There is no intrinsic demand for energy separable from supply; the demand for a resource reflects its availability. The Conservation Commission of the World Energy Conference used one study that predicted that if economic growth rates were to remain comparable to those of the last forty years, eight times the 1975 level of energy supply would be required by 2020. An alternative view suggested that if the income elasticity for energy declined with increasing economic development, there would be a fourfold increase in energy demand by 2020. Energy supply today and what it might be in 40 years is examined. The energy use of biomass will probably increase in certain areas of the world, but it is unlikely that there will be an overall growth in supply from this source. Energy production from fossil fuels may double between now and the early years of the next century, but unless the recovery rate of coal is increased drastically, growth will peak by mid-century. Hydro-electric and geothermal power may quadruple over the next forty years, but this will not represent a big increase in supply. Solar energy can make only a modest contribution in the next few decades. If there is to be a major increase in world energy supply, it must come from nuclear energy. The Conservation Commission felt that the potential for world energy supply is doubling between 1980 and 2000, and a further 50 percent growth to 2020. There will most likely be a 50 percent growth in per capita energy use around the world, with 3 to 4 percent annual growth rate in developing countries and perhaps the same in industrialized countries for the first 20 years, but about half that growth rate towards the end of the time period

    The individual kinematic roles of the anterolateral ligament (ALL) and the distal iliotibial band Kaplan fibers in the setting of anterior cruciate ligament (ACL) deficiency require further clarification. This will improve understanding of their potential contribution to residual anterolateral rotational laxity after ACL reconstruction and may influence selection of an anterolateral extra-articular reconstruction technique, which is currently a matter of debate. Hypothesis/Purpose: To compare the role of the ALL and the Kaplan fibers in stabilizing the knee against tibial internal rotation, anterior tibial translation, and the pivot shift in ACL-deficient knees. We hypothesized that the Kaplan fibers would provide greater tibial internal rotation restraint than the ALL in ACL-deficient knees and that both structures would provide restraint against internal rotation during a simulated pivot-shift test. Controlled laboratory study. Ten paired fresh-frozen cadaveric knees (n = 20) were used to investigate the effect of sectioning the ALL and the Kaplan fibers in ACL-deficient knees with a 6 degrees of freedom robotic testing system. After ACL sectioning, sectioning was randomly performed for the ALL and the Kaplan fibers. An established robotic testing protocol was utilized to assess knee kinematics when the specimens were subjected to a 5-N·m internal rotation torque (0°-90° at 15° increments), a simulated pivot shift with 10-N·m valgus and 5-N·m internal rotation torque (15° and 30°), and an 88-N anterior tibial load (30° and 90°). Sectioning of the ACL led to significantly increased tibial internal rotation (from 0° to 90°) and anterior tibial translation (30° and 90°) as compared with the intact state. Significantly increased internal rotation occurred with further sectioning of the ALL (15°-90°) and Kaplan fibers (15°, 60°-90°). At higher flexion angles (60°-90°), sectioning the Kaplan fibers led to significantly greater internal rotation

    2016-11-01

    This research presents numerical simulation of the unsteady flow field inside the draft tube of a Kaplan turbine at part load condition. Due to curvature of streamlines, the ordinary two-equations turbulence models fail to predict the flow features. Therefore, a modification of the Shear Stress Transport (SST-SAS) model is utilized to approximate the turbulent stresses. A guide vane, complete runner and draft tube are considered to insure the real boundary conditions at the draft tube inlet. The outlet boundary is assumed to discharge into the atmosphere. The obtained pressure fluctuations inside the draft tube are in good agreement with available experimental data. In order to further investigate the RVR formation and its movement, the λ2 criterion, relating the position of the vortex core and strength to the second largest Eigen value of the velocity gradient tensor, is employed. The method used for vortex identification shows the flow structure and vortex motion inside the draft tube accurately.

    Rapid pressure changes in hydroelectric turbine flows can cause barotrauma that can be hazardous to the passage of fish, in particular migratory juvenile salmonids. Although numerous laboratory tests have evaluated the effect of rapid decompression in fish species of relevance, numerical modeling studies offer the advantage of predicting, for new turbine designs, the potential risks of mortality and injury from rapid pressure change during turbine passage. However, rapid pressure change is only one of several hydraulic risks encountered by fish during turbine passage in addition to blade strike, shear, and turbulence. To better understand the role of rapid pressure changes, the present work focuses on the application of a computational fluid dynamics based method for evaluating the risk of pressure-related mortality to fish passing through an early 1960s era original hydroelectric Kaplan turbine at Wanapum Dam (Columbia River, Washington), and a modern advanced Kaplan turbine installed in 2005. The results show that the modeling approach acceptably reproduced the nadir pressure distributions compared to field data previously collected at the site using an autonomous sensor. Our findings show that the new advanced-design unit performs better, in terms of reduced barotrauma risk to fish from exposure to low pressures, than the original turbine unit. The outcomes allow for comparative analyses of turbine designs and operations prior to installation, an advantage that can potentially be integrated in the process of designing new turbine units to achieve superior environmental performance. Overall, the results show that modern turbine designs can achieve the multiple objectives of increasing power generation, lowering cavitation potential, and reducing barotrauma risks to passing fish.

    In spite of aiming at minimum maintenance costs, runners of Kaplan turbines need to be kept in good repair. Besides preserving their main function as an energy converter, ecological reasons have to be considered as well. The latter aspect accounts for fully functional, safe seals of the pivot-mounted Kaplan runner blades. Advanced wear of the sealing surfaces may require mechanical processing, which formerly called for a costly dismantling of the runner. A newly developed and patented processing device now allows for machining the worn out sealing surfaces without dismantling the runner, thus reducing costs considerably. The device was first successfully applied to a Kaplan turbine runner with a diameter of 5.35 m. The device, so far designed for grinding, will be enhanced for lathing, in order to obtain a process even more efficient when combining lathing and grinding. (orig.)

    We examined the accuracy of a highly-familiar-face representation in memory. In experiment 1, a famous portrait of Chairman Mao was digitally altered in terms of the distance between his two eyes, two pixels at a time. Mainland Chinese adults were shown the original or altered photos, one at a time, and asked to determine whether each was that of Chairman Mao or altered. Eastern Asian and Caucasian participants, who were unfamiliar with Mao's photo, were shown simultaneously the original face paired with the altered ones and asked to determine whether the photos were identical. The Mainland Chinese participants' memory threshold approximated the perceptual discrimination threshold of the Eastern Asian and Caucasian participants. Experiments 2 and 3 ruled out that the result of experiment I was due to artifacts of photographic alteration. The findings of the present study suggest that our memory of a very familiar face is highly accurate, at least in terms of the interocular configuration. The accuracy is perhaps only limited by the perceptual resolution capacity of our visual system.

  15. Biostatistics with emphasis on life table survival rate calculations (including Kaplan Meier) and the logrank test

    1995-01-01

    Purpose/Objective: To explain some of the most useful statistical calculation procedures which are relevant to radiation oncologists and to provide insights on what tests and procedures should be used in various situations such as when survival rates and their associated standard errors have to be determined. To describe some of the problems and pitfalls in clinical trial designs which have to be overcome if a trial is to have the possibility of reaching a successful conclusion. To review methods of computing criteria to quantitatively describe criteria of success (eg. quality of life, long-term survival, cure) of radiation oncology and to suggest possible future statistical improvements in this area. Chi-Squared Test: The chi-squared test is probably the most useful of the tests of statistical significance for the radiation oncologist. Applications will be described, including goodness of fit tests and 2x2 contingency tables which are the simplest of the generalized nxm contingency tables. Degrees of Freedom and P<0.05 for Significance Testing: An Introduction will be given to the meaning of P<0.05 in relation to significance testing and the use of tables of critical values of a test statistic (eg. chi-squared) which are given as a function of degrees of freedom and P-values. Survival Rate Calculations for Grouped and Ungrouped Data: The life-table method (sometimes termed the actuarial method) will be explained for both grouped data (eg. survival times grouped in annual intervals for patients who have died and for those who are still alive or lost to follow-up) and for ungrouped data (when individual survival times are used). The method for ungrouped data is variously termed the Kaplan-Meier or Product Limit method. Logrank Test: This is the most useful test for comparison of the survival experience of two groups of patients and its use will be explained. In part the computation is similar to that for the Kaplan-Meier/Product Limit method

    To determine the scientific production of Research Vice-chancellors at Peruvian universities that have medical schools, as well as their academic degrees as an indirect way to evaluate their suitability for the position they hold. We searched all Peruvian universities that register medical schools. Of these, the scientific production of the universities registered in SCOPUS was identified in September of the 2016. The scientific production of the vice chancellors of investigation of these faculties of medicine was determined through the search of its scientific publications registered in SCOPUS and those reported in the National Registry of Researchers in Science and Technology. Academic degrees were obtained from the database of the National Superintendence of Higher University Education. The sample included 28 research vice chancellors. Only 4/28 had any publications. The average number of articles published by the vice chancellors of research was 1.71, the number of citations 23.1 on average and the H index 0.64. Besides, 22 Vice-chancellors of research had the degree of doctor, four had the degree of bachelor and two the degree of master. The scientific production of research vice chancellors is poor. The required academic grade requirement for the position is not met in all cases. It is likely that, having no research experience, his leadership in directing a university's research policies may be questioned.

  1. Influence of the vibro-acoustic sensor position on cavitation detection in a Kaplan turbine

    Hydraulic turbines can be operated close to the limits of the operating range to meet the demand of the grid. When operated close to the limits, the risk increases that cavitation phenomena may occur at the runner and / or at the guide vanes of the turbine. Cavitation in a hydraulic turbine can cause material erosion on the runner and other turbine parts and reduce the durability of the machine leading to required outage time and related repair costs. Therefore it is important to get reliable information about the appearance of cavitation during prototype operation. In this experimental investigation the high frequency acoustic emissions and vibrations were measured at 20 operating points with different cavitation behaviour at different positions in a large prototype Kaplan turbine. The main goal was a comparison of the measured signals at different sensor positions to identify the sensitivity of the location for cavitation detection. The measured signals were analysed statistically and specific values were derived. Based on the measured signals, it is possible to confirm the cavitation limit of the examined turbine. The result of the investigation shows that the position of the sensors has a significant influence on the detection of cavitation.

    2018-05-04

    The current study aimed to determine whether the Delis-Kaplan Executive Function System (D-KEFS) taps into three executive function factors (inhibition, shifting, fluency) and to assess the relationship between these factors and tests of executive-related constructs less often measured in latent variable research: reasoning, abstraction, and problem solving. Participants included 425 adults from the D-KEFS standardization sample (20-49 years old; 50.1% female; 70.1% White). Eight alternative measurement models were compared based on model fit, with test scores assigned a priori to three factors: inhibition (Color-Word Interference, Tower), shifting (Trail Making, Sorting, Design Fluency), and fluency (Verbal/Design Fluency). The Twenty Questions, Word Context, and Proverb Tests were predicted in separate structural models. The three-factor model fit the data well (CFI = 0.938; RMSEA = 0.047), although a two-factor model, with shifting and fluency merged, fit similarly well (CFI = 0.929; RMSEA = 0.048). A bifactor model fit best (CFI = 0.977; RMSEA = 0.032) and explained the most variance in shifting indicators, but rarely converged among 5,000 bootstrapped samples. When the three first-order factors simultaneously predicted the criterion variables, only shifting was uniquely predictive (p measuring executive-related constructs and provide a framework through which clinicians can interpret D-KEFS results.

    2014-01-01

    Kaplan turbines operating at full-load conditions may undergo excessive vibration, noise and cavitation. In such cases, damage by erosion associated to tip vortex cavitation can be observed at the discharge ring. This phenomenon involves design features such as (1) overhang of guide vanes; (2) blade profile; (3) gap increasing size with blade opening; (4) suction head; (5) operation point; and (6) discharge ring stiffness, among others. Tip vortex cavitation may cause erosion at the discharge ring and draft tube inlet following a wavy pattern, in which the number of vanes can be clearly identified. Injection of pressurized air above the runner blade centerline was tested as a mean to mitigate discharge ring cavitation damage on a scale model. Air entrance was observed by means of a high-speed camera in order to track the air trajectory toward its mergence with the tip vortex cavitation core. Post-processing of acceleration signals shows that the level of vibration and the RSI frequency amplitude decrease proportionally with air flow rate injected. These findings reveal the potential mitigating effect of air injection in preventing cavitation damage and will be useful in further tests to be performed on prototype, aiming at determining the optimum air flow rate, size and distribution of the injectors

    2014-01-01

    Introduction of intermittent electricity production systems like wind power and solar systems to electricity market together with the consumption-based electricity production resulted in numerous start/stops, load variations and off-design operation of water turbines. The hydropower systems suffer from the varying loads exerted on the stationary and rotating parts of the turbines during load variations which they are not designed for. On the other hand, investigations on part load operation of single regulated turbines, i.e., Francis and propeller, proved the formation of rotating vortex rope (RVR) in the draft tube. The RVR induces oscillating flow both in plunging and rotating modes which results in oscillating force with two different frequencies on the runner blades, bearings and other rotating parts of the turbine. The purpose of this study is to investigate the effect of transient operations on the pressure fluctuations on the runner and mechanism of the RVR formation/mitigation. Draft tube and runner blades of the Porjus U9 model, a Kaplan turbine, were equipped with pressure sensors. The model was run in off-cam mode during different load variation conditions to check the runner performance under unsteady condition. The results showed that the transients between the best efficiency point and the high load happens in a smooth way while transitions to/from the part load, where rotating vortex rope (RVR) forms in the draft tube induces high level of fluctuations with two frequencies on the runner; plunging and rotating mode of the RVR

    This paper has been written to call attention to a potential danger what may occur in Kaplan turbine refurbishments. In Tiszalök hydropower plant, Hungary, the shaft sealing of the refurbished turbine was damaged. In searching for the reasons it was assumed that due to increased internal velocities in the turbine, the pressure at the hub clearance became lower than the atmospheric pressure, and therefore the sealing, which always operated satisfactorily before the refurbishment, had uncertain water supply, dry-running occurred, and after some time the sealing was burnt. First the flow conditions in the turbine and the pressure at the hub clearance were calculated by a one-dimensional flow model. Later this was refined by a two-dimensional approach. The above conclusion was also justified by the data acquisition system and by observing the operation of the small dewatering pump. When the turbine operated at a larger discharge than a certain limit value, then the dewatering pump remained standstill, indicating that no water passed through the shaft sealing. External water supply was then applied, and after this the turbine operated all right.

    In the current study, we examined the dimensionality of the 16-item Card Sorting subtest of the Delis-Kaplan Executive Functioning System assessment in a sample of 264 native English-speaking children between the ages of 9 and 15 years. We also tested for measurement invariance for these items across age and gender groups using item response theory (IRT). Results of the exploratory factor analysis indicated that a two-factor model that distinguished between verbal and perceptual items provided the best fit to the data. Although the items demonstrated measurement invariance across age groups, measurement invariance was violated for gender groups, with two items demonstrating differential item functioning for males and females. Multigroup analysis using all 16 items indicated that the items were more effective for individuals whose IRT scale scores were relatively high. A single-group explanatory IRT model using 14 non-differential item functioning items showed that for perceptual ability, females scored higher than males and that scores increased with age for both males and females; for verbal ability, the observed increase in scores across age differed for males and females. The implications of these findings are discussed.

    Bergant, A.; Gregorc, B.; Gale, J.

    2012-11-01

    This paper deals with critical flow regimes that may induce unacceptable water hammer in Kaplan turbine hydropower plants. Water hammer analysis should be performed for normal, emergency and catastrophic operating conditions. Hydropower plants with Kaplan turbines are usually comprised of relatively short inlet and outlet conduits. The rigid water hammer theory can be used for this case. For hydropower plants with long penstocks the elastic water hammer should be used. Some Kaplan turbine units are installed in systems with long open channels. In this case, water level oscillations in the channels should be carefully investigated. Computational results are compared with results of measurements in recently rehabilitated seven Drava river hydroelectric power plants in Slovenia. Water hammer in the six power plants is controlled by appropriate adjustment of the wicket gates and runner blades closing/opening manoeuvres. Due to very long inflow and outflow open channels in Zlatoličje HPP a special vaned pressure regulating device attenuates extreme pressures in Kaplan turbine flow-passage system and controls unsteady flow in both open channels. Comparisons of results include normal operating regimes. The agreement between computed and measured results is reasonable.

    Full Text Available Abstract Background The results of Randomized Controlled Trials (RCTs on time-to-event outcomes that are usually reported are median time to events and Cox Hazard Ratio. These do not constitute the sufficient statistics required for meta-analysis or cost-effectiveness analysis, and their use in secondary analyses requires strong assumptions that may not have been adequately tested. In order to enhance the quality of secondary data analyses, we propose a method which derives from the published Kaplan Meier survival curves a close approximation to the original individual patient time-to-event data from which they were generated. Methods We develop an algorithm that maps from digitised curves back to KM data by finding numerical solutions to the inverted KM equations, using where available information on number of events and numbers at risk. The reproducibility and accuracy of survival probabilities, median survival times and hazard ratios based on reconstructed KM data was assessed by comparing published statistics (survival probabilities, medians and hazard ratios with statistics based on repeated reconstructions by multiple observers. Results The validation exercise established there was no material systematic error and that there was a high degree of reproducibility for all statistics. Accuracy was excellent for survival probabilities and medians, for hazard ratios reasonable accuracy can only be obtained if at least numbers at risk or total number of events are reported. Conclusion The algorithm is a reliable tool for meta-analysis and cost-effectiveness analyses of RCTs reporting time-to-event data. It is recommended that all RCTs should report information on numbers at risk and total number of events alongside KM curves.

    Blade tip cavitation is a well-known phenomenon that affects the performance of large-diameter Kaplan turbines and induces structural vibration. Injection of pressurized air has been found to yield promising results in reducing those damaging effects. In this work, the results of an experimental test of air injection on a 9.5-m-diameter Kaplan turbine are reported. Experiments were performed for several load conditions and for two different net heads. Accelerations, pressure pulsation and noise emission were monitored for every tested condition. Results show that, at the expense of a maximum efficiency drop of 0.2%, air injection induces a decrease on the level of vibration from 57% up to 84%, depending on the load condition. Such decrease is seen to be proportional to the air flow rate, in the range from 0.06 to 0.8‰ (respect to the discharge at the best efficiency point).

    The role of the chairman of a surgery department is critical in academic surgery. However, little is known about the variability of job responsibilities. To evaluate chairmen's responsibilities, methods of support, determinants of job performance success, and concerns. Internet-based survey. Electronic survey system. Seventy-two chairmen. Survey data on job responsibilities, methods of support, determinants of job performance success, and concerns. Of 168 chairmen who received the survey, 72 (43%) responded. The mean age of chairmen was 57 years (range, 44-78 years). Of 72 chairmen who responded, 69 (96%) were men, 67 (93%) were white, 65 (90%) were professors, 11 (15%) held a previous chair, 35 (49%) have advanced degrees, and 19 (26%) are program directors. Respondents are responsible for an average of 8.7 divisions, 60 (83%) spent 1 to 10 hours per week in the clinic, 45 (63%) performed surgery 1 to 10 hours per week, 54 (75%) took less than 6 call days per month, 44 (61%) published 1 to 6 papers per year and attended a mean (SD) of 4.3 (1.7) essential meetings per year, and 48 (67%) took 1 to 3 weeks of vacation annually. Chair salary support includes (from least to most) faculty tax, grants, endowment, school, and hospital. Compensation correlates with age, additional degree, specialty, location, contract, and tenure but not clinical hours. Reported compensation was consistent with data from the Association of American Medical Colleges, but 24 (33%) felt undercompensated. Incentives for job performance were given for clinical productivity (34 chairmen [47%]), department performance (50 [70%]), institutional performance (27 [38%]), and personal accomplishment (14 [19%]). Of 72 chairmen, 30 (42%) were concerned about personal liability related to the job, 15 (21%) had purchased personal liability insurance, and 20 (28%) have defended a lawsuit related to nonclinical responsibilities. Academic surgery department chairmen have a wide array of responsibilities that

  14. Notes for remarks by William A. Farlinger, chairman of Ontario Hydro

    International Nuclear Information System (INIS)

    Farlinger, W.A.

    1997-01-01

    The advantages of convergence for gas and electric companies were discussed. Both utilities possess transmission lines, rights of way, billing systems and long-term customer relationships. The speaker, Chairman of Ontario Hydro, suggested that within a few years, customers may be in a position to choose their power supplier. Ontario Hydro's vision for convergence and the recent restructuring of the Corporation into three new signature companies (generation, transmission, retail) were described. In this process Ontario Hydro has taken steps toward open access to the grid by all producers, competition among many sellers and buyers, and choice of supplier by consumers for lower cost power. One of the basic driving forces for convergence in the energy field is the interchangeability of electricity or gas. Some municipalities have already implemented joint gas and electricity meter reading, and there are many other ways in which converge can provide cheaper power and better service to the consumer. Ultimately, convergence would mean that monopolies would disappear, as would the boundaries between the gas and electricity industries

    1989-01-01

    This introduction to my journal of 1961--1971, covering my years of service as Chairman of the US Atomic Energy Commission, is written from the perspective of 1971, in order to reflect the attitudes expressed in my journal, which was written on a daily basis during that period. Thus, I express the points of view of that time rather than those of today (1988), which might occasionally be somewhat different. The journal consists of 25 volumes, averaging 700 pages each. This comprises about 15,000 items consisting of the approximately 4,000 daily journal entries and the average of about three attachments per day. The journal has three sections corresponding to each of the three presidents I served as chairman of the Atomic Energy Commission -- the first six volumes covering the John F. Kennedy years (February 1, 1961--November 22, 1963), the next 11 volumes covering the Lyndon B. Johnson years (November 22, 1963--January 20, 1969) and the final eight volumes, the Richard M. Nixon years and a few months of post-AEC chairman activities in Washington (January 20, 1969--November 6, 1971)

  17. Evaluation of Hydraulic Loads on the Runner Blades of a Kaplan Turbine using CFD Simulation and Model Test

    Directory of Open Access Journals (Sweden)

    Zoltan-Iosif Korka

    2016-10-01

    Full Text Available CFD (Computational Fluid Dynamic is today a standard procedure for analyzing and simulating the flow through several hydraulic machines. In this process, the fluid flow domain is divided into small volumes where the governing equations are converted into algebraic ones, which are numerically solved. Computational results strongly depend on the applied mathematical model and on the numerical methods used for converting the governing equations into the algebraic ones. The goal of the paper is to evaluate, by numerical simulation, the hydraulic loads (forces and torques on the runner blades of an existent Kaplan turbine and to compare them with the experimental results obtained from model test.

    Full Text Available In order to increase the lifetime of runner blades of Kaplan turbines damaged by cavitation erosion, an anticavitation lip is attached to the periphery of the runner blades on the suction side. The anticavitation lip overtakes the cavitation pitting which appears between the runner blades and the runner chamber. A blade with the original anticavitation lip was modeled using CAE. The numerical simulations showed the tip vortex position and the source of the cavitation erosion. Using these data, a modified profile of the anticavitation lip was designed.

  20. Going Large or Going Small in Plant Design: Comparison between a P.P. with three small Kaplan turbines and a P.P. with just one Large Kaplan turbine

    Castro-Otero, C.

    2017-04-01

    Very often small turbine manufacturers are requested to produce sizeable turbines, too large in terms of physical dimensions, power or designing capacity. In these cases clever alternative solutions should be found to meet customers’ needs. For instance: in the old times twin runner Francis turbines were an option instead of one large machine, or if a too large Pelton turbine cannot be manufactured or designed, a good option is to install a medium size Francis and a small Pelton. Likewise, a similar approach needs to be taken should the manufacturer be asked for a too large Kaplan. Facing this situation a good option is to install three or more small Kaplan turbines. This particular case was studied in depth and after all the considerations had been made, the following question arouse: Is this a way out for the manufacturer or is it really the best option for the customer? The choice made as a way out for the manufacturer became the best option for the customer and a success for both parties. This paper aims to encourage developers and engineering firms to search for more options than the traditional one to find the best option in plant design.

  1. Tariff Reduction Effects of WTO/DDA Agricultural Negotiations: Analysis of the Chairman's Second Draft Text

    2003-06-01

    Full Text Available The average tariff reduction rate is 20% point higher in five developed countries analyzed in this study compared to five developing countries following the direction offered by the Chairman's Draft Text. Average tariff reduction rates are 31.6% for the five developing countries and 51.4% for the five developed countries. Korea's tariff reduction rate reaches to 36.1%, the highest reduction in developing countries, when Korea retains the developing country status. When Korea makes tariff reductions following the direction for developed countries, the average tariff reduction rate rises to 55.8%. Tariff reductions following the second Draft Text affect the tariff structure. Tariff escalation, dispersion and peaks can be mitigated by applying the tariff reduction methods proposed in the Second Draft Text. Tariff reductions give rise to the effects of reducing tariff escalation problem and the effects are stronger for the commodities with higher tariff rates and in developed countries. The average tariff rate for tariff peak commodities is reduced by 40% in developing countries and by 60% in developed countries. Tariff dispersion is also mitigated by reducing tariff rates. The difference of the average tariff rate between Korea and Australia is reduced to 38.5% from 59.8% by cutting tariff rates with the rules proposed in the second Draft Text. Korea needs to prepare the Country Schedule in advance to evaluate the potential outcome of the tariff cut following the Draft Text and to capture various voices from producers, consumers and other related institutions. For the preparation of the Country Schedule, Korea needs to decide minimum tariff cut items within a group of the commodity classified by tariff rates and this procedure requires discussion among producer and consumer groups.

  2. Virtues, Vices, and Political Influence in the U.S. Senate.

    2016-01-01

    What qualities make a political leader more influential or less influential? Philosophers, political scientists, and psychologists have puzzled over this question, positing two opposing routes to political power--one driven by human virtues, such as courage and wisdom, and the other driven by vices, such as Machiavellianism and psychopathy. By coding nonverbal behaviors displayed in political speeches, we assessed the virtues and vices of 151 U.S. senators. We found that virtuous senators became more influential after they assumed leadership roles, whereas senators who displayed behaviors consistent with vices--particularly psychopathy--became no more influential or even less influential after they assumed leadership roles. Our results inform a long-standing debate about the role of morality and ethics in leadership and have important implications for electing effective government officials. Citizens would be wise to consider a candidate's virtue in casting their votes, which might increase the likelihood that elected officials will have genuine concern for their constituents and simultaneously promote cooperation and progress in government. © The Author(s) 2015.

    It has been suggested that obesity is associated with an altered rate of gastric emptying, and that there are also sex differences in gastric emptying. The results of earlier studies examining gastric emptying rates in obesity and in males and females have proved inconsistent. The aim of this study was to investigate the influence of obesity and gender on gastric emptying, by extending conventional evaluation methods with Kaplan-Meier plots, in order to assess whether these factors have to be accounted for when interpreting results of scintigraphic gastric emptying tests. Twenty-one normal-weight volunteers and nine obese subjects were fed a standardised technetium-99m labelled albumin omelette. Imaging data were acquired at 5- and 10-min intervals in both posterior and anterior projections with the subjects in the sitting position. The half-emptying time, analysed by Kaplan-Meier plot (log-rank test), were shorter in obese subjects compared to normal-weight subjects and later in females compared to males. Also, the lag-phase and half-emptying time were shorter in obese females than in normal females. This study shows an association between different gastric emptying rates and obesity and gender. Therefore, body mass index and gender have to be accounted for when interpreting results of scintigraphic gastric emptying studies. (orig.). With 6 figs., 4 tabs

  5. Virus-Induced Chaperone-Enriched (VICE domains function as nuclear protein quality control centers during HSV-1 infection.

    Directory of Open Access Journals (Sweden)

    Christine M Livingston

    2009-10-01

    Full Text Available Virus-Induced Chaperone-Enriched (VICE domains form adjacent to nuclear viral replication compartments (RC during the early stages of HSV-1 infection. Between 2 and 3 hours post infection at a MOI of 10, host protein quality control machinery such as molecular chaperones (e.g. Hsc70, the 20S proteasome and ubiquitin are reorganized from a diffuse nuclear distribution pattern to sequestration in VICE domains. The observation that VICE domains contain putative misfolded proteins suggests that they may be similar to nuclear inclusion bodies that form under conditions in which the protein quality control machinery is overwhelmed by the presence of misfolded proteins. The detection of Hsc70 in VICE domains, but not in nuclear inclusion bodies, indicates that Hsc70 is specifically reorganized by HSV-1 infection. We hypothesize that HSV-1 infection induces the formation of nuclear protein quality control centers to remodel or degrade aberrant nuclear proteins that would otherwise interfere with productive infection. Detection of proteolytic activity in VICE domains suggests that substrates may be degraded by the 20S proteasome in VICE domains. FRAP analysis reveals that GFP-Hsc70 is dynamically associated with VICE domains, suggesting a role for Hsc70 in scanning the infected nucleus for misfolded proteins. During 42 degrees C heat shock, Hsc70 is redistributed from VICE domains into RC perhaps to remodel viral replication and regulatory proteins that have become insoluble in these compartments. The experiments presented in this paper suggest that VICE domains are nuclear protein quality control centers that are modified by HSV-1 to promote productive infection.

    2012-01-01

    Analysis of clinical studies often necessitates multiple graphical representations of the results. Many professional software packages are available for this purpose. Most packages are either only commercially available or hard to use especially if one aims to generate or customize a huge number of similar graphical outputs. We developed a new, freely available software tool called KMWin (Kaplan-Meier for Windows) facilitating Kaplan-Meier survival time analysis. KMWin is based on the statistical software environment R and provides an easy to use graphical interface. Survival time data can be supplied as SPSS (sav), SAS export (xpt) or text file (dat), which is also a common export format of other applications such as Excel. Figures can directly be exported in any graphical file format supported by R. On the basis of a working example, we demonstrate how to use KMWin and present its main functions. We show how to control the interface, customize the graphical output, and analyse survival time data. A number of comparisons are performed between KMWin and SPSS regarding graphical output, statistical output, data management and development. Although the general functionality of SPSS is larger, KMWin comprises a number of features useful for survival time analysis in clinical trials and other applications. These are for example number of cases and number of cases under risk within the figure or provision of a queue system for repetitive analyses of updated data sets. Moreover, major adjustments of graphical settings can be performed easily on a single window. We conclude that our tool is well suited and convenient for repetitive analyses of survival time data. It can be used by non-statisticians and provides often used functions as well as functions which are not supplied by standard software packages. The software is routinely applied in several clinical study groups.

    Directory of Open Access Journals (Sweden)

    Jiraporn Napatsorn

    2016-07-01

    Full Text Available Consumers often choose virtue food to attain health goals and vice food to achieve indulgence goals. However, food and beverage companies have begun to nullify the vice and virtue categories by bundling vice and virtue ingredients into a single item (e.g. Yogurt with Oreo topping. This research contrasts how consumers from Asian and Western cultures evaluate such vice/virtue food bundles. Building on the perceptual processes and regulatory focus literatures, two cross-cultural experiments using participants in Thailand and the U.S. shows that Westerners prefer virtue-heavy bundles to vice-heavy bundles while Asians show similar preference across both types of bundle. Process measures revealed that Asians perceive greater fit between vice and virtue components in the bundles than Westerners and this perceived fit mediates the effect of culture on their food choice. Study 2 reveals the boundary condition. Specifically, when regulatory focus was manipulated, the effect of culture is no longer significant. The findings provide managerial implications for food and beverage companies as well as contributions to consumer behavior literature.

    Although celebrity illnesses attract a significant amount of media attention in the United States, there are few studies that have looked at how celebrity health conditions impact the awareness of the illness in the general population. Recently, Vice President Cheney underwent left ventricular assist device (LVAD) implantation and subsequently a cardiac transplant. The aim of this study was to determine whether there was evidence of increased interest in these 2 procedures as assessed by social media. We determined the relative frequency of Google searches for LVAD and heart transplantation from 2004 to 2013 using Google trends. We also counted the number of YouTube videos and Twitter messages posted monthly concerning LVADs over a 7-year time frame. There was a significant spike in the Google search interest for LVAD and heart transplantation in the month when Vice President Cheney underwent the respective procedure. Similarly, there was a large increase in YouTube videos and Twitter messages concerning LVADs shortly after he was implanted. In total, these data support the concept that a public figure's illness can significantly influence the public's interest in that condition and its associated therapies.

    The aim of the study is to investigate coexistence of Wormian bones with metopism, and vice versa, in adult skulls. A total of 160 dry adult human skulls of unknown sex and ages were randomly selected from the Gross Anatomy Laboratory of Medical School of Dokuz Eylul University. The skulls were examined for presence of metopism, Wormian bones (WB), and coexistence of WBs with metopism and vice versa. Topographic distribution of the WBs was macroscopically evaluated within the skulls including metopism. The photographs were being taken with Canon 400B (55 mm objective). The frequency of metopism and WBs in 160 skulls is 7.50% (12/160) and 59.3% (95/160), respectively, P coexistence of WBs with metopism was found as 11 of 12 skulls (91.66%), whereas the incidence of coexistence of metopism with WBs was found as 11 of 95 skulls (11.58%), P coexistence of WBs with metopism (11/12, 91.66%) and coexistence of metopism with WBs (11/95, 11.58%). The factors leading to metopism may also lead to WBs, whereas that the factors leading to WBs may not lead to metopism.

    Kaplan-Meier survival analysis overestimates cumulative incidence in competing risks (CRs) settings. The extent of overestimation (or its clinical significance) has been questioned, and CRs methods are infrequently used. This meta-analysis compares the Kaplan-Meier method to the cumulative incidence function (CIF), a CRs method. We searched MEDLINE, EMBASE, BIOSIS Previews, Web of Science (1992-2016), and article bibliographies for studies estimating cumulative incidence using the Kaplan-Meier method and CIF. For studies with sufficient data, we calculated pooled risk ratios (RRs) comparing Kaplan-Meier and CIF estimates using DerSimonian and Laird random effects models. We performed stratified meta-analyses by clinical area, rate of CRs (CRs/events of interest), and follow-up time. Of 2,192 identified abstracts, we included 77 studies in the systematic review and meta-analyzed 55. The pooled RR demonstrated the Kaplan-Meier estimate was 1.41 [95% confidence interval (CI): 1.36, 1.47] times higher than the CIF. Overestimation was highest among studies with high rates of CRs [RR = 2.36 (95% CI: 1.79, 3.12)], studies related to hepatology [RR = 2.60 (95% CI: 2.12, 3.19)], and obstetrics and gynecology [RR = 1.84 (95% CI: 1.52, 2.23)]. The Kaplan-Meier method overestimated the cumulative incidence across 10 clinical areas. Using CRs methods will ensure accurate results inform clinical and policy decisions.

    The molecularly cloned infectious Kaplan radiation leukemia virus has previously been shown to be unable to replicate on mouse fibroblasts. To map the viral sequences responsible for this, we constructed chimeric viral DNA genomes in vitro with parental cloned infectious viral DNAs from the nonfibrotropic (F-) BL/VL3 V-13 radiation leukemia virus and the fibrotropic (F+) endogenous BALB/c or Moloney murine leukemia viruses (MuLV). Infectious chimeric MuLVs, recovered after transfection of Ti-6 lymphocytes with these recombinant DNAs, were tested for capacity to replicate on mouse fibroblasts in vitro. We found that chimeric MuLVs harboring the long terminal repeat (LTR) of a fibrotropic MuLV replicated well on mouse fibroblasts. Conversely, chimeric MuLVs harboring the LTR of a nonfibrotropic MuLV were restricted on mouse fibroblasts. These results indicate that the LTR of BL/VL3 radiation leukemia virus harbors the primary determinant responsible for its inability to replicate on mouse fibroblasts in vitro. Our results also show that the primary determinant allowing F+ MuLVs (endogenous BALB/c and Moloney MuLVs) to replicate on mouse fibroblasts in vitro resides within the LTR

    As an important component of the blade-control system in Kaplan turbines, piston rods are subjected to fluctuating forces transferred by the turbines blades from hydraulic pressure oscillations. Damage due to unsteady hydraulic loads might generate unexpected down time and high repair cost. In one running hydropower plant, the fracture failure of the piston rod was found twice at the same location. With the transient dynamic analysis, the retainer ring structure of the piston rod existed a relative high stress concentration. This predicted position of the stress concentration agreed well with the actual fracture position in the plant. However, the local strain approach was not able to explain why this position broke frequently. Since traditional structural fatigue analyses use a local stress strain approach to assess structural integrity, do not consider the effect of flaws which can significantly degrade structural life. Using linear elastic fracture mechanism (LEFM) approaches that include the effect of flaws is becoming common practice in many industries. In this research, a case involving a small semi-ellipse crack was taken into account at the stress concentration area, crack growth progress was calculated by FEM. The relationship between crack length and remaining life was obtained. The crack propagation path approximately agreed with the actual fracture section. The results showed that presence of the crack had significantly changed the local stress and strain distributions of the piston rod compared with non-flaw assumption

    This paper deals with the optimization of the axial hydraulic turbines of Kaplan type. The optimization of the runner blade is presented systematically from two points of view: hydrodynamic and constructive. Combining these aspects in order to gain a safer operation when unsteady effects occur in the runner of the turbine is attempted. The design and optimization of the runner blade is performed with QTurbo3D software developed at the Center for Research in Hydraulics, Automation and Thermal Processes (CCHAPT) from 'Eftimie Murgu' University of Resita, Romania. QTurbo3D software offers possibilities to design the meridian channel of hydraulic turbines design the blades and optimize the runner blade. 3D modeling and motion analysis of the runner blade operating mechanism are accomplished using SolidWorks software. The purpose of motion study is to obtain forces, torques or stresses in the runner blade operating mechanism, necessary to estimate its lifetime. This paper clearly states the importance of combining the hydrodynamics with the structural design in the optimization procedure of the runner of hydraulic turbines.

  20. A versatile test for equality of two survival functions based on weighted differences of Kaplan-Meier curves.

    With censored event time observations, the logrank test is the most popular tool for testing the equality of two underlying survival distributions. Although this test is asymptotically distribution free, it may not be powerful when the proportional hazards assumption is violated. Various other novel testing procedures have been proposed, which generally are derived by assuming a class of specific alternative hypotheses with respect to the hazard functions. The test considered by Pepe and Fleming (1989) is based on a linear combination of weighted differences of the two Kaplan-Meier curves over time and is a natural tool to assess the difference of two survival functions directly. In this article, we take a similar approach but choose weights that are proportional to the observed standardized difference of the estimated survival curves at each time point. The new proposal automatically makes weighting adjustments empirically. The new test statistic is aimed at a one-sided general alternative hypothesis and is distributed with a short right tail under the null hypothesis but with a heavy tail under the alternative. The results from extensive numerical studies demonstrate that the new procedure performs well under various general alternatives with a caution of a minor inflation of the type I error rate when the sample size is small or the number of observed events is small. The survival data from a recent cancer comparative study are utilized for illustrating the implementation of the process. Copyright © 2015 John Wiley & Sons, Ltd.

    1975-03-01

    The post of vice president for the health sciences was first developed in an attempt to interpret, modulate, and buffer the growing power of the medical school in the university and the different values that have existed there. The job has been greatly transformed over the past 10 years as a consequence of a variety of factors. Now a genuine creative effort applied to the design of the administration of health sciences centers and how they fit into universities is needed. The present modes of organization are not equal to the challenges that must be faced. New designs must be created which will recognize the special place of the health sciences in today's world and yet keep its function within the university frame.

  2. Utopia and Debt in Postmodernity; or, Time Management in Inherent Vice

    Directory of Open Access Journals (Sweden)

    James Liner

    2016-05-01

    Full Text Available The category of postmodernism has come under renewed scrutiny in recent years. Indeed, it has become rather commonplace to pronounce the death or obsolescence of postmodernism today. Unsurprisingly, the increasingly questioned status of postmodernism also impacts the field of Pynchon studies. This article reads 'Inherent Vice' as symptomatic not of the end but of a transformation of postmodernism and postmodernity. Pynchon’s novel simultaneously registers a contemporary intensification of postmodern/late capitalism and, crucially, participates in a minor current in postmodernism, one which insists on collective agency and utopian thinking despite the atomization and isolation of subjects accomplished by late capitalism and which, against all odds, remembers how to think historically—or better, invents new ways of thinking historically.

    2017-04-01

    In this article we address how Realistic Mathematics Education (RME) principles, including the intertwinement and the reality principles, are used to analyze geometry tasks. To do so, we carried out three phases of a small-scale study. First we analyzed four geometry problems - considered as tasks inviting the use of problem solving and reasoning skills - theoretically in the light of the RME principles. Second, we tested two problems to 31 undergraduate students of mathematics education program and other two problems to 16 master students of primary mathematics education program. Finally, we analyzed student written work and compared these empirical to the theoretical results. We found that there are discrepancies between what we expected theoretically and what occurred empirically in terms of mathematization and of intertwinement of mathematical concepts from geometry to algebra and vice versa. We conclude that the RME principles provide a fruitful framework for analyzing geometry tasks that, for instance, are intended for assessing student problem solving and reasoning skills.

    2012-07-01

    The growing appreciation of the need to adopt an evidence-based approach to teaching and assessment has led to a demand for faculty who are well versed in best practices in education. Surgeons with interest and expertise in instruction, curriculum development, educational research, and evaluation can have an important impact on the educational mission of a department of surgery. The increased fervor for accountability in education together with the challenges imposed by accreditation agencies and hospitals has made educational leadership responsibilities more time consuming and complex. In response to this, an increasing number of department chairs created Vice Chair for Education positions to support clerkship and program directors and ensure the department's education mission statement is fulfilled.

  9. Design of a Kaplan turbine for a wide range of operating head -Curved draft tube design and model test verification-

    2016-11-01

    As for turbomachine off-design performance improvement is challenging but critical for maximising the performing area. In this paper, a curved draft tube for a medium head Kaplan type hydro turbine is introduced and discussed for its significant effect on expanding operating head range. Without adding any extra structure and working fluid for swirl destruction and damping, a carefully designed outline shape of draft tube with the selected placement of center-piers successfully supresses the growth of turbulence eddy and the transport of the swirl to the outlet. Also, more kinetic energy is recovered and the head lost is improved. Finally, the model test results are also presented. The obvious performance improvement was found in the lower net head area, where the maximum efficiency improvement was measured up to 20% without compromising the best efficiency point. Additionally, this design results in a new draft tube more compact in size and so leads to better construction and manufacturing cost performance for prototype. The draft tube geometry parameter designing process was concerning the best efficiency point together with the off-design points covering various water net heads and discharges. The hydraulic performance and flow behavior was numerically previewed and visualized by solving Reynolds-Averaged Navier-Stokes equations with Shear Stress Transport turbulence model. The simulation was under the assumption of steady-state incompressible turbulence flow inside the flow passage, and the inlet boundary condition was the carefully simulated flow pattern from the runner outlet. For confirmation, the corresponding turbine efficiency performance of the entire operating area was verified by model test.

    Rémy Willemet is above all a local botanist whose first work was selected by the academy of Nancy in 1766. His notoriety began when another work with Jean-François Coste was chosen by the academy of Lyon ten years later. He published then in many papers and was elected in numerous academies and scientific societies. During the Revolution, he was a professor of the Ecole centrale de la Meurthe and of the Société de santé, and he became the chairman of the botanical garden. Willemet wrote some botanical books. Today, what is the memory of his researchs and papers? Fairly few things because he never undertook botanical travels in order to discover and compare pharmaceutical plants. However, Willemetia was the name used to denominate some species and honour his family. His name was also engraved on the wall of some university buidings and it was chosen some years ago to entitle a botanical paper in Lorraine.

    presidente. Y el vicepresidente puede esperar, a su vez, proyección hacia el futuro, incluso la sucesión presidencial. Así se ha señalado que constituye un campo de experiencia y preparación para el cargo máximo: hacia finales del siglo XX trece de los cuarenta presidentes norteamericanos sirvieron en la vicepresidencia. En síntesis, en este estudio se brinda un enfoque de análisis de la vicepresidencia y se tratan algunos de los problemas que ha presentado en los países de America Latina. Luego se realiza un análisis de la experiencia norteamericana y de la evolución de la institución en ese país. El análisis del caso norteamericano resulta útil para iniciar un debate sobre la vicepresidencia en la región, para explorar una necesaria agenda de investigación y como una de las alternativas posibles a la hora de su reforma. In the Presidential Regimes of Latin America, the institution of the Vice Presidency has been barely studied, unlike that of the United States. It only received some comments from authors such as Juan Linz, doubting its effectiveness and pointing out some of the issues surrounding its figure, like the criteria for nomination of candidates and conflicts with the Presidents. But Vice Presidency was practically not taken into account in the debate on presidencialism and parlamentarism, despite being the second place of importance in a presidential regime. With democracy back in the region, Vice Presidency has generated numerous political problems, but there virtually isn’t any academic debate on this. Severe tensions and conflicts between the President and Vice President, even Vice Presidents turned into opponent, are some of the problems observed. On the other hand, some Vice Presidents have taken, with varying success, the role of President be it because of the former’s death or because of political crisis that culminated with the resignation of the President. In the United States, historically, there has been a devalued image of Vice

    Full Text Available In the process of impeachment, Constitutional Court has the obligation to give its judgement to House of Representatives’s opinion regarding allegation of violation by the President and/or Vice President. Constitutional Court checks and judges House of Representatives’s opinion on whether or not the President and/or Vice President works fulfill Article 7A of Constitution of Republic Indonesia 1945 (UUD NRI 1945. The inspection done by Constitutional Court is the judicial process whose decision is in the form of justisil. The result of this impeachment process heavily depends on the judgement of People's Consultative Assembly in its plenary meeting which is also a politics forum, where President and/or Vice President could be dismissed or not. Constitutional Court’s judgement does not apply to People's Consultative Assembly, hence, the difference of Constitutional Court and People's Consultative Assembly’s judgement in plenary meeting that is very political by its nature is very likely to happen. Involvement of Constitutional Court in the procss of impeachment is, of course, different in each country. It depends on governance system in that particular country, it also relies on how much authority that is given by Constitution to Constitutional Court in the process of impeachment itself.

  12. The vices of emperor Constans I in the fourth century histories

    Directory of Open Access Journals (Sweden)

    Milivojević Uroš

    2008-01-01

    Full Text Available The aim of this paper is to analyze the negative characteristics of the Roman emperor Constans I (337-350, according to the earliest preserved information from the late 4th century histories of Aurelius Victor, Eutropius Pseudo-Victor and Eunapius of Sardis. The earliest account of Constans' downfall is around 361 recorded by Aurelius Victor in his short history De Caesaribus. Victor wrote that Constans became more arrogant and aggressive after he defeated his elder brother Constantine II in 340. Also, he was not cautious enough for his young age, was hated due to his bad subordinates and did not respect his soldiers properly. But, the most outrageous fact was according to Victor, that the emperor had homosexual affinity towards his young and attractive barbarian hostages. The record of less moralistic Eutropius in his Breviarium ab Urbe condita, written in 369, is shorter but sharper. In the beginning the reign of Constans was vigorous and righteous but his character deteriorated after his illness. Following that, the young Augustus befriended himself with corrupted companions and turned to severe vices. His reign grew unbearable to his subjects and unpopular among the army ranks. Briefer then Eutropis is the testimony of an anonymous Latin author of Epitome de caesaribus who was contemporary to the Eastern Roman emperor Arcadius (395-408. This Pseudo-Victor wrote down that Constans devoted himself to hunting session, thus allowing plotters to dethrone him. Finally the single Greek author in this series, Eunapius (died after 404, whose istoria h meta Dexippon survived in fragments and Zosimus' late fifth century abridgment, called Constans the worst among the most intolerable tyrants. The Lydian sophist, as far as we could conclude from Zosimus', also recorded Constans' inclination towards young barbarians whom he allowed to mistreat his subjects. Because of wretchedness in the provinces of his realm, the courtiers led coup d'etat through

The integration techniques used in these both methods are different from the recommendations contained in the relevant international standards, mainly from the graphical and arithmetical ones. The results of the comparative analysis of both methods applied at the same time during the hydraulic performance tests of two Kaplan turbines in one of the Polish hydropower plant are presented in the final part of the paper. In the case of the pressure-time method application, the concrete penstocks of the tested turbines required installing a special measuring instrumentation inside the penstock. The comparison has shown a satisfactory agreement between the results of discharge measurements executed using the both considered methods. Maximum differences between the discharge values have not exceeded 1.0 % and the average differences have not been greater than 0.5 %.

    2012-06-01

    A full three dimensional Navier - Stokes numerical simulation has been performed for performance analysis of a Kaplan turbine which is installed in one of the Irans south dams. No simplifications have been enforced in the simulation. The numerical results have been evaluated using some integral parameters such as the turbine efficiency via comparing the results with existing experimental data from the prototype Hill chart. In part of this study the numerical simulations were performed in order to calculate the prototype turbine efficiencies in some specific points which comes from the scaling up of the model efficiency that are available in the model experimental Hill chart. The results are very promising which shows the good ability of the numerical techniques for resolving the flow characteristics in these kind of complex geometries. A parametric study regarding the evaluation of turbine performance in three different runner angles of the prototype is also performed and the results are cited in this paper.

  2. Combining food type(s) and food quantity choice in a new food choice paradigm based on vice-virtue bundles.

    Haws, Kelly L; Liu, Peggy J

    2016-08-01

    Given the prevalence and rising rates of obesity in many countries, including the United States, much food decision-making research ultimately aims at understanding how consumers can make healthier choices. The two predominant choice paradigms used in food decision-making research ask consumers to choose (a) between a "vice" (or unhealthy food) and a "virtue" (or healthy food) or (b) among varying portion sizes of "vice." We propose a new food choice paradigm that encourages consumers to jointly consider both food type(s) choice and food portion size at each decision point. The purpose of this paradigm is two-fold. First, it aims to allow examination of more comprehensive eating behavior (e.g., to examine the overall composition of a plate of food rather than choice of a single food). Second, it aims to shift consumers towards including large proportions of virtues and smaller proportions of vice in their overall consumption portfolios. For this paradigm, we draw upon a recently introduced food product innovation called "vice-virtue bundles" (Liu et al., 2015) that illustrates the basis of this new food choice paradigm, in which food type(s) and portion decisions are made simultaneously. Accordingly, we first discuss relevant findings on vice-virtue bundles as well as the differences between simultaneous and sequential choice of multiple products. Second, we examine the benefits for managing and controlling one's consumption that are provided by vice-virtue bundles and this joint food choice paradigm more generally. Third and finally, we point out opportunities for future research by discussing (a) multiple factors that influence food choices, (b) decision processes affected by food choice paradigms, and (c) issues of generalizability related to the presence of vice-virtue bundles.

    2016-12-01

    Full Text Available This paper looks into the characterisation of Satan as the Capital Vice of Pride in John Milton’s Paradise Lost. It thus supports the findings of Robert Charles Fox, who in his study The Seven Deadly Sins in Paradise Lost first thoroughly analysed and comprehensively presented this issue and its importance in Milton’s epic. The authors of the study share Fox’s belief that Milton consciously used the system of the Seven Capital Vices in his epic as a structural device to present the entire scope of evil to the willing reader, and he achieved this by giving Satan and six other major denizens of Hell each the characteristics of a particular Vice. In other words, each of the seven major diabolical figures that appear in Paradise Lost embodies or personifies one of the Seven Capital Vices. As the most eloquent and characteristically perfected of the diabolical figures of Hell, Satan embodies Pride, the prime Capital Vice.

  9. From “Goal-Orientated, Strong and Decisive Leader” to “Collaborative and Communicative Listener”. Gendered Shifts in Vice-Chancellor Ideals, 1990–2018

    Directory of Open Access Journals (Sweden)

    Helen Peterson

    2018-06-01

    Full Text Available Applying a critical gendered lens, this article examines academic leadership ideals. It draws on a content analysis of job advertisements for Vice-Chancellors at Swedish higher education institutions from 1990 until 2018. The aim of the article is to investigate to what extent masculine or feminine wordings have been used to describe the ideal Vice-Chancellor in these documents. The analysis reveals that a shift in the leadership ideal has taken place during the time period investigated. Before this shift, during the 1990s, the ideal Vice-Chancellor was described as competitive, bold, strong, tough, decisive, driven, and assertive. These wordings are still included in the job advertisements from the 2000s and the 2010s. However, a more communicative and collaborative leadership ideal also emerges during these decades. There is thus a significant shift in how the leadership ideal is described. This shift is analyzed from a gendered perspective, suggesting that the traditional masculine-biased leadership ideal has decreased in influence with the feminine, transformational leadership ideal acting as a counterweight. The article argues that the shift in leadership ideals, as constructed in the job advertisements, mirrors the increase of women Vice-Chancellors appointed in the Swedish higher education sector.

    2012-03-01

    To examine how genes and environments contribute to relationships among Trail Making Test (TMT) conditions and the extent to which these conditions have unique genetic and environmental influences. Participants included 1,237 middle-aged male twins from the Vietnam Era Twin Study of Aging. The Delis-Kaplan Executive Function System TMT included visual searching, number and letter sequencing, and set-shifting components. Phenotypic correlations among TMT conditions ranged from 0.29 to 0.60, and genes accounted for the majority (58-84%) of each correlation. Overall heritability ranged from 0.34 to 0.62 across conditions. Phenotypic factor analysis suggested a single factor. In contrast, genetic models revealed a single common genetic factor but also unique genetic influences separate from the common factor. Genetic variance (i.e., heritability) of number and letter sequencing was completely explained by the common genetic factor while unique genetic influences separate from the common factor accounted for 57% and 21% of the heritabilities of visual search and set shifting, respectively. After accounting for general cognitive ability, unique genetic influences accounted for 64% and 31% of those heritabilities. A common genetic factor, most likely representing a combination of speed and sequencing, accounted for most of the correlation among TMT 1-4. Distinct genetic factors, however, accounted for a portion of variance in visual scanning and set shifting. Thus, although traditional phenotypic shared variance analysis techniques suggest only one general factor underlying different neuropsychological functions in nonpatient populations, examining the genetic underpinnings of cognitive processes with twin analysis can uncover more complex etiological processes.

    2016-09-01

    Cognitive set shifting requires flexible application of lower level processes. The Delis-Kaplan Executive Functioning System (DKEFS) Color-Word Interference Test (CWIT) is commonly used to clinically assess cognitive set shifting. An atypical pattern of performance has been observed on the CWIT; a subset of individuals perform faster, with equal or fewer errors, on the more difficult inhibition/switching than the inhibition trial. This study seeks to explore the cognitive underpinnings of this atypical pattern. It is hypothesized that atypical patterns on CWIT will be associated with better performance on underlying cognitive measures of attention, working memory, and learning when compared to typical CWIT patterns. Records from 239 clinical referrals (age: M = 68.09 years, SD = 10.62; education: M = 14.87 years, SD = 2.73) seen for a neuropsychological evaluation as part of diagnostic work up in an outpatient dementia and movement disorders clinic were sampled. The standard battery of tests included measures of attention, learning, fluency, executive functioning, and working memory. Analyses of variance (ANOVAs) were conducted to compare the cognitive performance of those with typical versus atypical CWIT patterns. An atypical pattern of performance was confirmed in 23% of our sample. Analyses revealed a significant group difference in acquisition of information on both nonverbal (Brief Visuospatial Memory Test-Revised, BVMT-R total recall), F(1, 213) = 16.61, p < .001, and verbal (Hopkins Verbal Learning Test-Revised, HVLT-R total recall) learning tasks, F(1, 181) = 6.43, p < .01, and semantic fluency (Animal Naming), F(1, 232) = 7.57, p = .006, with the atypical group performing better on each task. Effect sizes were larger for nonverbal (Cohen's d = 0.66) than verbal learning (Cohen's d = 0.47) and semantic fluency (Cohen's d = 0.43). Individuals demonstrating an atypical pattern of performance on the CWIT inhibition/switching trial also demonstrated relative

    Plants have evolved a limited repertoire of NB-LRR disease resistance ( R ) genes to protect themselves against myriad pathogens. This limitation is thought to be counterbalanced by the rapid evolution of NB-LRR proteins, as only a few sequence changes have been shown to be sufficient to alter resistance specificities toward novel strains of a pathogen. However, little is known about the flexibility of NB-LRR R genes to switch resistance specificities between phylogenetically unrelated pathogens. To investigate this, we created domain swaps between the close homologs Gpa2 and Rx1 , which confer resistance in potato ( Solanum tuberosum ) to the cyst nematode Globodera pallida and Potato virus X , respectively. The genetic fusion of the CC-NB-ARC of Gpa2 with the LRR of Rx1 (Gpa2 CN /Rx1 L ) results in autoactivity, but lowering the protein levels restored its specific activation response, including extreme resistance to Potato virus X in potato shoots. The reciprocal chimera (Rx1 CN /Gpa2 L ) shows a loss-of-function phenotype, but exchange of the first three LRRs of Gpa2 by the corresponding region of Rx1 was sufficient to regain a wild-type resistance response to G. pallida in the roots. These data demonstrate that exchanging the recognition moiety in the LRR is sufficient to convert extreme virus resistance in the leaves into mild nematode resistance in the roots, and vice versa. In addition, we show that the CC-NB-ARC can operate independently of the recognition specificities defined by the LRR domain, either aboveground or belowground. These data show the versatility of NB-LRR genes to generate resistance to unrelated pathogens with completely different lifestyles and routes of invasion. © 2017 American Society of Plant Biologists.

  14. Commentary: linking health equity with economic development: insights from my year as Chairman of the Board of the Chamber of Commerce.

    Clancy, Gerard P

    2012-12-01

    Many urban areas struggle with significant health disparities. In Tulsa, Oklahoma, there is a 14-year difference in life expectancy between the predominantly African American population in north Tulsa and the predominantly Caucasian population in south Tulsa. The roots of Tulsa's health disparities can be linked, in part, to a long history of racial mistrust stemming from the 1921 Tulsa Race Riot, arguably one of the worst race riots in U.S. history. In 2011, the author served as both a university campus president and chairman of the board of the Tulsa region's chamber of commerce. Through his work with the chamber, he discovered the business community's substantial resources and advocacy abilities. He also found that regional business leaders strongly supported health equity, diversity, and inclusion initiatives, both as moral obligations and regional economic development imperatives. After sharing the lessons he learned from working closely with business leaders, the author encourages other academic health centers (AHCs) to reach out to their business communities, which are likely willing and able to help them undertake similar initiatives. In doing so, AHCs and businesses can work together to improve the economic vitality of their regions.

    Urology, having been part of general surgery for centuries, was completely consolidated as a medical speciality in the middle of the XX Century as the result of years of evolution and development, and all the studies and works of certain authors that represent today the mainstays of our speciality. Valencia in the middle of the 20th century saw the birth of new hospitals including the "Ciudad Sanitaria La Fe". Alfredo Tramoyeres Cases was the first chairman of the Department of Urology. This article reviews his long and fertile professional life. We have reviewed all his scientific works. The articles have been obtained from Medicina Española, Revista Española de Cirugía Traumatológica y Ortopedia, and Archivos Españoles de Urología. His most important urological work is his doctoral thesis with the title "Sigmoid-procto-ureterostomy: personal modification" published in Valencia in 1976. For his biography we used the" Biographic and bibliographic history of the Spanish Urology over the XX century" and interviews with family members. We emphasize his thorough description of the various types of urinary diversion. He covers the topics of bladder diverticula and bladder neck disorders, in which he supports surgical treatment. Finally, he sets out the rupture of the posterior urethra and various treatments for prostate cancer at that time. Alfredo Tramoyeres Cases contributed to the definitive consolidation of our speciality in the area of Valencia during the second half of the XX century, through his long professional life, with his interesting scientific contributions.

  13. Thyrotropin-Blocking Autoantibodies and Thyroid-Stimulating Autoantibodies: Potential Mechanisms Involved in the Pendulum Swinging from Hypothyroidism to Hyperthyroidism or Vice Versa

    Science.gov (United States)

    Rapoport, Basil

    2013-01-01

    Background Thyrotropin receptor (TSHR) antibodies that stimulate the thyroid (TSAb) cause Graves' hyperthyroidism and TSHR antibodies which block thyrotropin action (TBAb) are occasionally responsible for hypothyroidism. Unusual patients switch from TSAb to TBAb (or vice versa) with concomitant thyroid function changes. We have examined case reports to obtain insight into the basis for “switching.” Summary TBAb to TSAb switching occurs in patients treated with levothyroxine (LT4); the reverse switch (TBAb to TSAb) occurs after anti-thyroid drug therapy; TSAb/TBAb alterations may occur during pregnancy and are well recognized in transient neonatal thyroid dysfunction. Factors that may impact the shift include: (i) LT4 treatment, usually associated with decreased thyroid autoantibodies, in unusual patients induces or enhances thyroid autoantibody levels; (ii) antithyroid drug treatment decreases thyroid autoantibody levels; (iii) hyperthyroidism can polarize antigen-presenting cells, leading to impaired development of regulatory T cells, thereby compromising control of autoimmunity; (iv) immune-suppression/hemodilution reduces thyroid autoantibodies during pregnancy and rebounds postpartum; (v) maternally transferred IgG transiently impacts thyroid function in neonates until metabolized; (vi) a Graves' disease model involving immunizing TSHR-knockout mice with mouse TSHR-adenovirus and transfer of TSHR antibody-secreting splenocytes to athymic mice demonstrates the TSAb to TBAb shift, paralleling the outcome of maternally transferred “term limited” TSHR antibodies in neonates. Finally, perhaps most important, as illustrated by dilution analyses of patients' sera in vitro, TSHR antibody concentrations and affinities play a critical role in switching TSAb and TBAb functional activities in vivo. Conclusions Switching between TBAb and TSAb (or vice versa) occurs in unusual patients after LT4 therapy for hypothyroidism or anti-thyroid drug treatment for Graves

  11. Clinicopathological features and the value of differential Cytokeratin 7 and 20 expression in resolving diagnostic dilemmas of ovarian involvement by colorectal adenocarcinoma and vice-versa

    Directory of Open Access Journals (Sweden)

    Full Text Available Abstract The distinction between metastasis from a colorectal adenocarcinoma into the ovary and an ovarian adenocarcinoma is vital, but challenging at times, due to overlapping morphological features. Similarly, a distinction between an ovarian metastasis into the colorectum and a colorectal adenocarcinoma, although rare; is important and can be daunting. We report an analysis of 20 cases of ovarian involvement by metastatic colorectal adenocarcinomas and colorectal involvement by metastatic ovarian adenocarcinomas, including the value of differential expression of cytokeratins 7 & 20 by immunohistochemistry (IHC, in these cases. Nine cases (45% were identified as colorectal adenocarcinomas metastatic to the ovary. On biopsy, all these cases showed a 'garland-like' tumor necrosis, with desmoplasia and predominantly exhibited a tubuloalveolar pattern (67% cases. On IHC, all 8 of 9 such cases, where staining for cytokeratin 20 was performed, displayed strong positivity and 7 cases, where staining for carcinoembryogenic antigen (CEA was performed, revealed positivity for this marker (100%. Other 11 cases (55% were ovarian adenocarcinomas, metastatic to the colorectum. These showed metachronous presentations, with the ovarian tumor preceding the colorectal tumor deposits. Morphologically, psammomatous calcification was noted in 73% of these cases, whereas 'garland-like' necrosis was absent in all. The chief morphological subtype was serous papillary cystadenocarcinoma (55% cases. On IHC, CK7 and CA 125 were positive in all 6 of 11 such cases, whereas CK 20 was negative in all these cases. In cases of complex presentations like an ovarian involvement by a metastatic colorectal adenocarcinoma and vice-versa, certain clinicopathological features are useful. Differential expression of CK 7 and CK20 is vital in resolving these dilemmas. CK20 positivity and CK7 negativity is associated with a colorectal adenocarcinoma. Markers like CEA and CA-125 have an

  12. Are fear-avoidance beliefs in low back pain patients a risk factor for low physical activity or vice versa? A cross-lagged panel analysis

    2009-01-01

    Objective: The assumption that low back pain (LBP) patients suffer from “disuse” as a consequence of high fear-avoidance beliefs is currently under debate. A secondary analysis served to investigate whether fear-avoidance beliefs are associated cross-sectionally and longitudinally with the physical activity level (PAL) in LBP patients. Methods: A total of 787 individuals (57% acute and 43% chronic LBP) were followed up over a period of one year with measurements of fear-avoidance beliefs and physical activity level. Fear-avoidance beliefs concerning physical activity were measured by the physical-activity subscale of the FABQ (Fear-Avoidance Beliefs Questionnaire), the physical activity level was assessed in weighted metabolic equivalents (MET) hours/week with a German self-report questionnaire. Data were investigated by structural equation modelling in a cross-lagged panel design for the whole sample and separately for acute and chronic LBP. Results: The acute and chronic sub sample increased their total physical activity level significantly after one year. The structural equation modelling results did not support the disuse-aspect inherent in the fear-avoidance belief model. Cross-lagged path coefficients were low (.04 and .05 respectively) and, therefore, did not allow to predict final physical activity by initial fear-avoidance beliefs or vice versa. Discussion: Consequently, due to missing links between fear-avoidance beliefs and physical activity in a longitudinal design, the assumptions of the fear-avoidance belief model have to be questioned. These findings are in line with other investigations published recently. Most probably, “fear-avoidance belief” represents a cognitive scheme that does not limit activity per se, but only is directed to the avoidance of specific movements. PMID:19742047

  13. Opium: The Evolution of Policies, the Tolerance of the Vice, and the Proliferation of Contraband Trade in the Philippines, 1843-1908

    Full Text Available This research entitled “Opium: The Evolution of Policies, the Tolerance of the Vice, and the Proliferation of Contraband Trade in the Philippines, 1843-1908” presents a discussion of the opium trade in Asia, the commercial networks it created, the political ties it strengthened, and the social relations itfostered. It also aims to reconstruct an aspect of Philippine social history in the nineteenth century through the use of archival materials that bear witness to the distribution and exploitation of a substance which some people stillclassify as taboo. The poppy was not endemic to the Philippines but opium, its derivative substance, was known to numb pain and could induce a “natural high” that left one with feelings of ease and contentment. A more complete introduction to the drug necessitates a discussion of the way it was extractedand processed. It is a cash crop that does not require complex devices and is, therefore, within the reach of farmers and common folk. From the eighteenth to the nineteenth centuries opium became very popular among the Chinese who discovered that their markets were being flooded with it by the British sothat the latter could pay for the tea that they craved.The Spanish Bourbons, in an effort to boost Philippine economy, allowed the trading of this substance. Initially this was supervised by the officials of the Alcaiceria de San Fernando but in 1843 the meticulous examination of the country’s finances merited the creation of an opium revenuefarm through municipal franchising. Opium could only be used by the Chinese who were migrating in big groups. This paper presents the details of the monopoly contract, identifies some of the wealthier contratistas of the period, and discusses the consequences of such a commercial venture. Smuggling orcontraband trade proliferated and by way of illustration the events namely, the Scandal of 1843 and the Gunga Incident, have been narrated. The creation of an over

    This paper reviews the huge promotion of Chairman Mao Zedong's two poems entitled "Farewell to the God of Plague" which were published 60 years ago, and the great achievements of the national schistosomiasis control programme in China. The publication of the two poems promotes the establishment of the mechanism for the national schistosomiasis control programme in China, and in addition, the schistosomiasis control spirit of the people from Yujiang County is still the source of power for the promotion of transferring the schistosomiasis control to elimination stage in China. Now, that we commemorate the 60th anniversary of publishing Chairman Mao Zedong's two poems entitled "Farewell to the God of Plague" means we remain the true to our original aspiration to serve the people forever, which is also to promote the progress of schistosomiasis elimination in China according to the law, the scientific principle, and local conditions, so as to contribute our efforts for realizing the healthy China's dream.

  20. Sociology as Moral Philosophy (and Vice Versa).

    Science.gov (United States)

    Vandenberghe, Frédéric

    2017-11-01

    In this article, I want to make an attempt to reconnect sociology to moral philosophy and moral philosophy to sociology. The thesis I want to defend is that sociology continues by other means the venerable tradition of practical and moral philosophy. Like its forebears, it stands and falls with a defense of "practical wisdom" (Aristotle) and "practical reason" (Kant). The development of a moral sociology presupposes, however, that one recognizes and rejects Max Weber's theory of axiological neutrality as an extremist position and that one carefully articulates prescriptive and descriptive, internal and external, as well as observer and actor positions. © 2017 Canadian Sociological Association/La Société canadienne de sociologie.

    Governments frequently allocate resources at low prices and on a first-come-first-served basis because of reasons of equity and a concern for the poor. However, bureaucrats who distribute these resources often take bribes. This paper develops a rigorous model to analyze the distributional, efficiency and public policy implications of bribery in such situations. It is shown that at low prices, the poor would choose to wait while the rich would pay the bribe to obtain the rationed commodity. If...

  10. “And You, Vampire, Admiral Napier, Don’t Expect the Banquet”. The Case on the Surveillance of the British Vice-Admiral Sir Charles Napier in St. Petersburg in 1856

    Directory of Open Access Journals (Sweden)

    Aleksandr A. Orlov

    2016-12-01

    Full Text Available The Crimean War of 1853-1856 provoked the hostility between the Russian and the English peoples. This had contributed to the confrontational thinking in the consciousness of the two peoples. The changes in mentality had for a long time been anchored through the efforts of the authorities and the media of that time (newspapers, magazines and cartoons. Military operations had led to the fact that their members had realized the disparity of the imposed stereotypes. Disappointment with propaganda clichés prompted some British to think over the reason for their personal failure, to get acquainted closer with the life of former enemies and to inform the public of their country about truth. The author carries out the analysis of unpublished archival documents from the State Archive of the Russian Federation (GA RF, which allow talking about the visit of former commander of the Baltic squadron of the English fleet, Vice-Admiral Ch.J. Napier to St. Petersburg in July 1856, and the surveillance of him by the Russian security police. Ch. J. Napier, motivated by the concepts of personal honour, aimed to get the Russian authorities’ confirmation of the correctness of his actions in the maritime campaign of 1854. He partially succeeded, but the Emperor Alexander II was not willing to meet with him. Ch.J. Napier had not succeeded in gaining justification from the British authorities either. Apparently, neither Russian nor British government no longer needed a positive image of the other country. The Russian-British relations had been tense (or worse throughout the rest part of the 19th century. Russia reoriented to France and (to a lesser extent to the United States, while Britain found itself at the threshold of the “splendid isolation” era. Only the appearance of Germany as a dangerous enemy, which had established at the borders of the British colonial possessions in different parts of the world and had finally broken the “balance of powers” in

El proceso se realiza en tres etapas: desde el decreto de Unificación (19-04-1937, hasta el primer gobierno civil del régimen de Franco (31-01-1938; desde este mismo primer gobierno civil hasta la consolidación de la influencia de Serrano Súnyer (16-11-1940, acceso de Serrano a la cartera de relaciones internacionales; por fin, desde esta fecha, a la creación de la Vice Secretaría. El proceso consistió en externalizar las competencias intelectuales falangistas en un primer tiempo, de manera que no puedan actuar dentro de la administración del Movimiento sino directamente bajo el control del Estado (1937. Luego, en una segunda etapa, se instrumentalizaron estas competencias para organizar las estructuras administrativas de propaganda del nuevo Estado (1938-1940.

A finales de 1943, la Vice Secretaría ya es una enorme máquina administrativa generadora de empleos y sometida al Estado. Su traspaso en 1945 al Ministerio de la Educación — entonces entre las manos de los conservadores católicos— confirma que la era de los funcionarios del franquismo ya se ha sustituido a la de los militantes falangistas.

  2. Why cognitive science needs philosophy and vice versa.

    Science.gov (United States)

    Thagard, Paul

    2009-04-01

    Contrary to common views that philosophy is extraneous to cognitive science, this paper argues that philosophy has a crucial role to play in cognitive science with respect to generality and normativity. General questions include the nature of theories and explanations, the role of computer simulation in cognitive theorizing, and the relations among the different fields of cognitive science. Normative questions include whether human thinking should be Bayesian, whether decision making should maximize expected utility, and how norms should be established. These kinds of general and normative questions make philosophical reflection an important part of progress in cognitive science. Philosophy operates best, however, not with a priori reasoning or conceptual analysis, but rather with empirically informed reflection on a wide range of findings in cognitive science.

  4. From iron(III) precursor to magnetite and vice versa

    International Nuclear Information System (INIS)

    Gotic, M.; Jurkin, T.; Music, S.

    2009-01-01

    The syntheses of nanosize magnetite particles by wet-chemical oxidation of Fe 2+ have been extensively investigated. In the present investigation the nanosize magnetite particles were synthesised without using the Fe(II) precursor. This was achieved by γ-irradiation of water-in-oil microemulsion containing only the Fe(III) precursor. The corresponding phase transformations were monitored. Microemulsions (pH ∼ 12.5) were γ-irradiated at a relatively high dose rate of ∼22 kGy/h. Upon 1 h of γ-irradiation the XRD pattern of the precipitate showed goethite and unidentified low-intensity peaks. Upon 6 h of γ-irradiation, reductive conditions were achieved and substoichiometric magnetite (∼Fe 2.71 O 4 ) particles with insignificant amount of goethite particles found in the precipitate. Hydrated electrons (e aq - ), organic radicals and hydrogen gas as radiolytic products were responsible for the reductive dissolution of iron oxide in the microemulsion and the reduction Fe 3+ → Fe 2+ . Upon 18 h of γ-irradiation the precipitate exhibited dual behaviour, it was a more oxidised product than the precipitate obtained after 6 h of γ-irradiation, but it contained magnetite particles in a more reduced form (∼Fe 2.93 O 4 ). It was presumed that the reduction and oxidation processes existed as concurrent competitive processes in the microemulsion. After 18 h of γ-irradiation the pH of the medium shifted from the alkaline to the acidic range. The high dose rate of ∼22 kGy/h was directly responsible for this shift to the acidic range. At a slightly acidic pH a further reduction of Fe 3+ → Fe 2+ resulted in the formation of more stoichiometric magnetite particles, whereas the oxidation conditions in the acidic medium permitted the oxidation Fe 2+ → Fe 3+ . The Fe 3+ was much less soluble in the acidic medium and it hydrolysed and recrystallised as goethite. The γ-irradiation of the microemulsion for 25 h at a lower dose rate of 16 kGy/h produced pure substoichiometric nanosize magnetite particles of about 25 nm in size and with the stoichiometry of Fe 2.83 O 4 .

  5. Passive margins getting squeezed in the mantle convection vice

    Passive margins often exhibit uplift, exhumation and tectonic inversion. We speculate that the compression in the lithosphere gradually increased during the Cenozoic. In the same time, the many mountain belts at active margins that accompany this event seem readily witness this increase. However, how that compression increase affects passive margins remains unclear. In order to address this issue, we design a 2D viscous numerical model wherein a lithospheric plate rests above a weaker mantle. It is driven by a mantle conveyor belt, alternatively excited by a lateral downwelling on one side, an upwelling on the other side, or both simultaneously. The lateral edges of the plate are either free or fixed, representing the cases of free convergence, and collision or slab anchoring, respectively. This distinction changes the upper boundary condition for mantle circulation and, as a consequence, the stress field. Our results show that between these two regimes, the flow pattern transiently evolves from a free-slip convection mode towards a no-slip boundary condition above the upper mantle. In the second case, the lithosphere is highly stressed horizontally and deforms. For an equivalent bulk driving force, compression increases drastically at passive margins provided that upwellings are active. Conversely, if downwellings alone are activated, compression occurs at short distances from the trench and extension prevails elsewhere. These results are supported by Earth-like 3D spherical models that reveal the same pattern, where active upwellings are required to excite passive margins compression. These results support the idea that compression at passive margins, is the response to the underlying mantle flow, that is increasingly resisted by the Cenozoic collisions.

    Energetic particles in the heliosphere can be measured at their elevated energetic status after three processes: injection, acceleration, and transport. Suprathermal seed particles have speeds well above the fast magnetosonic speed in the solar wind frame of reference and can vary from location to location and within the solar activity cycle. Acceleration sites include reconnecting current sheets in solar flares or magnetspheric boundaries, shocks in the solar corona, heliosphere and a planetary obstacles, as well as planetary magnetospheres. Once accelerated, particles are transported from the acceleration site into and through the heliosphere. Thus, by investigating properties of energetic particles such as their composition, energy spectra, pitch-angle distribution, etc. one can attempt to distinguish their origin or injection and acceleration site. This in turn allows us to better understand transport effects whose underlying microphysics is also a key ingredient in the acceleration of particles. In this presentation we will present some clear examples which link energetic particles from their observing site to their source locations. These include Jupiter electrons, singly-charged He ions from CIRs, and 3He from solar flares. We will compare these examples with the measurement capabilities of the Energetic Particle Detector (EPD) on Solar Orbiter and consider implications for the key science goal of Solar Orbiter and Solar Proble Plus - How the Sun creates and controls the heliosphere.

  7. From substance use to homelessness or vice versa?

    Science.gov (United States)

    McVicar, Duncan; Moschion, Julie; van Ours, Jan C

    2015-07-01

    Homelessness is associated with substance use, but whether substance use precedes or follows homelessness is unclear. We investigate the nature of the relationship between homelessness and substance use using data from the unique Australian panel dataset Journeys Home collected in 4 surveys over the period from October 2011 to May 2013. Our data refer to 1325 individuals who were homeless or at risk of becoming homeless. We investigate dynamics in homelessness and substance use over the survey period. We find that the two are closely related: homeless individuals are more likely to be substance users and substance users are more likely to be homeless. These relationships, however, are predominantly driven by observed and unobserved individual characteristics which cause individuals to be both more likely to be homeless and to be substance users. Once we take these personal characteristics into account it seems that homelessness does not affect substance use, although we cannot rule out that alcohol use increases the probability that an individual becomes homeless. These overall relationships also hide some interesting heterogeneity by 'type' of homelessness. Copyright © 2015 Elsevier Ltd. All rights reserved.

  19. Adapting computational text analysis to social science (and vice versa

    Directory of Open Access Journals (Sweden)

    Paul DiMaggio

    2015-11-01

    Full Text Available Social scientists and computer scientist are divided by small differences in perspective and not by any significant disciplinary divide. In the field of text analysis, several such differences are noted: social scientists often use unsupervised models to explore corpora, whereas many computer scientists employ supervised models to train data; social scientists hold to more conventional causal notions than do most computer scientists, and often favor intense exploitation of existing algorithms, whereas computer scientists focus more on developing new models; and computer scientists tend to trust human judgment more than social scientists do. These differences have implications that potentially can improve the practice of social science.

  20. Text Mining to Support Gene Ontology Curation and Vice Versa.

    Science.gov (United States)

    Ruch, Patrick

    2017-01-01

    In this chapter, we explain how text mining can support the curation of molecular biology databases dealing with protein functions. We also show how curated data can play a disruptive role in the developments of text mining methods. We review a decade of efforts to improve the automatic assignment of Gene Ontology (GO) descriptors, the reference ontology for the characterization of genes and gene products. To illustrate the high potential of this approach, we compare the performances of an automatic text categorizer and show a large improvement of +225 % in both precision and recall on benchmarked data. We argue that automatic text categorization functions can ultimately be embedded into a Question-Answering (QA) system to answer questions related to protein functions. Because GO descriptors can be relatively long and specific, traditional QA systems cannot answer such questions. A new type of QA system, so-called Deep QA which uses machine learning methods trained with curated contents, is thus emerging. Finally, future advances of text mining instruments are directly dependent on the availability of high-quality annotated contents at every curation step. Databases workflows must start recording explicitly all the data they curate and ideally also some of the data they do not curate.

    A simplified procedure has been developed, compared to the complex one recommended by IEC 60041 (i.e. index samples), for measurement of the performance of the hydraulic turbines. The simplified procedure determines the minimum and maximum powers, the efficiency at maximum power, the evolution of powers by head and flow and to determine the correct relationship between runner/impeller blade angle and guide vane opening for most efficient operation of double-regulated machines. The simplified procedure can be used for a rapid and partial estimation of the performance of hydraulic turbines for repair and maintenance work.

    Many scientists as well as representatives from UN organizations and governments of affected regions participated in the work of the Chernobyl Forum. Several meetings of the Forum were necessary to initiate the work and monitor the progress of the expert groups. Two expert groups formulated comprehensive reports - one on environmental issues, organized by the IAEA, and one on health issues, organized by the WHO. Experts from throughout the world were invited to contribute to these evaluations. The representatives of governments and the staff of international organizations then reviewed the results of these groups to be sure that the reviews were complete and the evaluations reasonable, so that they could serve as the basis for consensus agreements and effective recommendations for further dealing with the consequences of the accident

    Mr. President, As I had the opportunity to tell you last June, we are satisfied that, at your initiative, better communication has been put into place towards the members and beneficiaries of the Pension Fund who, I am sure, appreciate your decision to publish regularly articles in the CERN Bulletin. In your article in No. 30+31 dated 25 July 2012, you mention that the Fund continues the implementation of the capital preservation approach and you announce a return on investments by the Fund of 2.0% as of 31 May 2012. You compare this number to a change by -8.5% in the Eurostoxx50 index. The Fund’s return is certainly more favourable than the one obtained in 2011, but we should not forget that an evaluation of the Fund’s performance has to take into account two elements: its return objective fixed at 3% above inflation , and the result of a comparison with other providence schemes. A direct estimate of the quality of the management of our Fund is possible by making comparisons with ins...

    Full Text Available My choice of grounded theory as research approach has been made against the background of three factors. The first and foremost is that my research interest evolved when I carried out two interviews with survivors who were children themselves during the Holocaust, i.e. from the data. The information that I obtained gave me a strong sense of urgency, a motivation, to try to understand the major concerns for child survivors, based on their own perspective. I decided to start doctoral studies after many years in clinical practice. My interest thus emerged from the interviews and not from an existing theory. Grounded theory is a method that sticks closely to the empirical and that aims to create theoretical models based on the development of concepts, of relationships between concepts and of theories concerning social and psychological processes from a certain aspect tied to a special context (Glaser, 1978.

  12. Making visible the invisible and vice versa. Bodies and organisational arrangements in the Intensive Care Unit.

    2016-11-22

    The effectiveness of the treatments carried out in the Intensive Care Unit (ICU) is guaranteed by a socio-technical ensemble where material resources, scientific knowledge, technological artefacts, social norms, spatial dispositions, and professional practices coexist and constantly interact. This paper intends to penetrate such an ensemble for analysing the moral order produced and maintained in everyday medical practice. The results of a case study, carried out in the ICU of a hospital in the north of Italy between 2006 and 2007 are reported. The study was performed using ethnographic methods: participant observation, ethnographic interviews, and semi-structured interviews. I illustrate how ward organisation and professional practices of medical and nurse staff create and reproduce two dispositions of body centred on the staff's perception of the therapeutic appropriateness of patients. On one side, there are the bodies that staff expect to get better, and these bodies are exposed through a series of organisational devices and activities in order to make them immediately accessible and available for every type of treatment; on the other side, the bodies of chronic and terminal patients tend to become invisibles in the working practice of the unit. This process does not follow any guideline or protocol but is embodied in informal routine and communicative interactions. The invisibility surrounding certain patients can be seen as strategies for the management of professional conflict and bioethical issues that stem from different interpretations of the degree of severity of the patients' conditions.

  13. All order running coupling BFKL evolution from GLAP (and vice versa)

    International Nuclear Information System (INIS)

    Ball, Richard D.; Forte, Stefano

    2006-01-01

    We present a systematic formalism for the derivation of the kernel of the BFKL equation from that of the GLAP equation and conversely to any given order, with full inclusion of the running of the coupling. The running coupling is treated as an operator, reducing the inclusion of running coupling effects and their factorization to a purely algebraic problem. We show how the GLAP anomalous dimensions which resum large logs of 1x can be derived from the running-coupling BFKL kernel order by order, thereby obtaining a constructive all-order proof of small x factorization. We check this result by explicitly calculating the running coupling contributions to GLAP anomalous dimensions up to next-to-next-to leading order. We finally derive an explicit expression for BFKL kernels which resum large logs of Q 2 up to next-to-leading order from the corresponding GLAP kernels, thus making possible a consistent collinear improvement of the BFKL equation up to the same order

    The increasing mobility of media has in recent years led some scholars to argue for a decline in the significance of place in relation to media. This chapter argues for the importance of understanding media as vitally emplaced in the phenomenological world and it uses violent conflict to develop...... this point. Drawing on ethnographic fieldwork with information activists and journalists during the Egyptian uprising, this chapter contests understandings of media as doubling or making place insignificant. Rather, it develops an understanding of media as place-making to allow for an analysis...... of the entanglements of people and things related to media, showing how media are emplaced in the phenomenological world in the same way that violence is. Doing so, the chapter sheds light on how media can contribute to opening up places to other places and thus influence movements of people and things in conflict....

  16. Privatisation in Nigeria: A critical analysis of the virtues and vices

    Directory of Open Access Journals (Sweden)

    Dare E. Arowolo

    2012-12-01

    Full Text Available The twin-problems of mismanagement and corruption encountered by the state-owned corporations constitute the impetus for the recent privatisation of those corporations in Nigeria. Private sector seems, however, inseparable from public sector as viable public sector serves as guide for the private sector. It goes on to reason that a decaying public sector would give rise to inefficient private sector. Also, private sector has its own inherent contradictions as privatization in itself is not an antidote to corruption and mismanagement of which the public sector is being accused. The controversy and the contradictions in this topical issue aroused the interest and concern of this paper. The focus of the paper, therefore, is to present the two sides of the arguments on the viability of privatisation. The paper adopted content analysis in driving home its points.

  18. The Saga of Two Centuries of Urea: Nontoxic Toxin or Vice Versa?

    Science.gov (United States)

    Duranton, Flore; Depner, Thomas A; Argilés, Àngel

    2014-03-01

    In the early 1700s, a substance ultimately identified as urea was reported for the first time in urine. About a century later, in 1828, synthesis of this organic compound was achieved, thus giving rise to modern organic chemistry. In parallel, physicians showed that urine comes from the kidneys and contains large amounts of urea, which is produced outside of the kidneys, establishing the humoral approach of renal physiology. Urea was the first uremic retention solute to be identified and it has been used as a marker of renal disease ever since. However, progress in the knowledge of urea metabolism has shown that it is susceptible to many extrarenal variations and, therefore, it cannot be a reliable marker of renal function. It reflects protein intake in the stable patient and has been used to assess nutrition and dialysis efficacy in renal patients. Although it has been studied for almost 200 years, its toxicity has been largely debated. An indirect toxicity occurring through carbamylation of lysine residues is now well established and some evidence from recent work also supports direct toxicity of urea, offering additional rationale for interventional prevention of uremic complications.

  1. Why Rules Matter in Complex Event Processing...and Vice Versa

    Science.gov (United States)

    Vincent, Paul

    Many commercial and research CEP solutions are moving beyond simple stream query languages to more complete definitions of "process" and thence to "decisions" and "actions". And as capabilities increase in event processing capabilities, there is an increasing realization that the humble "rule" is as relevant to the event cloud as it is to specific services. Less obvious is how much event processing has to offer the process and rule execution and management technologies. Does event processing change the way we should manage businesses, processes and services, together with their embedded (and hopefully managed) rulesets?

    Membranes are important components in a number of systems, where separation and control of the flow of molecules is desirable. Controllable membranes represent an even more coveted and desirable entity and their development is considered to be the next step of development. Typically, membranes are considered on flat surfaces, but spherical capsules possess a perfect "infinite" or fully suspended membranes. Similarities and transitions between spherical and flat membranes are discussed, while applications of membranes are also emphasized.

    Wagner, Louis K. [The University of Texas - Houston Medical School, Department of Diagnostic and Interventional Imaging, Houston, TX (United States)

    2014-10-15

    Diagnostic radiology has an image problem. In its effort to develop a better understanding of benefit-risk in medical radiology, data on potential risks associated with medical imaging have been welcomed into the medical community. As such, risk perspectives and mantras from the occupational health profession have been adopted and applied to patients. These perspectives often focus on risk with only casual, incidental, or no reference to the benefits experienced by patients. These occupational health viewpoints have accumulated over decades, have overshadowed a very limited perspective about the benefits of medical X-rays, and have become an integrated part of our profession. This review argues that the medical profession should abandon perspectives on risk that are adopted from occupational health professions and focus on perspectives that realistically focus on the medical benefit-risk for patients.

    1999-04-01

    The disagreement over whether standards governing radioactive release should be general, internationally acceptable principles or site specific, contextualized standards reminds the ethicist of the deep disagreement between egalitarian and utilitarian ideals. One should set criteria for health and environment standards that would be acceptable to all rational agents, despite the contexts of needs and desires within which the agents are enmeshed. Remove the veil which masks the moral agent and were she to discover herself to be a subset critical-group member (e.g. a pregnant woman living in Armagosa Valley, Nevada), she would nevertheless find the standards acceptable. This egalitarianism is further justified by the belief that it is morally impermissible not to respect every human being, oneself or any other, as a rational creature. Site-specific standards are viewed with askance in the belief that regulations tailored to specific situations will more likely than not result in political opportunism, i.e. treating some human beings with inequity. But, one need only cite the difficulties of the egalitarian position to provide the human community with practical solutions to easily see why one might think that the utilitarian view supports site-specific standards. Appealing to the John Stuart Mill`s principle of utility, whereby one`s moral obligation is to achieve the greater overall good, regulators who seek to create these standards are freed from the moral constraints imposed by the pure rational agent. Impure reasoning, which attends to context, is not only permissible, it is desirable and even obligatory. Regulators are motivated by pragmatic considerations, which morally legitimate the imposition of risks on a small number for the benefit of the overall good. Site specific standards infused with utility get a needed job done and that is good enough 10 refs.

  7. How cultural evolutionary theory can inform social psychology and vice versa.

    Science.gov (United States)

    Mesoudi, Alex

    2009-10-01

    Cultural evolutionary theory is an interdisciplinary field in which human culture is viewed as a Darwinian process of variation, competition, and inheritance, and the tools, methods, and theories developed by evolutionary biologists to study genetic evolution are adapted to study cultural change. It is argued here that an integration of the theories and findings of mainstream social psychology and of cultural evolutionary theory can be mutually beneficial. Social psychology provides cultural evolution with a set of empirically verified microevolutionary cultural processes, such as conformity, model-based biases, and content biases, that are responsible for specific patterns of cultural change. Cultural evolutionary theory provides social psychology with ultimate explanations for, and an understanding of the population-level consequences of, many social psychological phenomena, such as social learning, conformity, social comparison, and intergroup processes, as well as linking social psychology with other social science disciplines such as cultural anthropology, archaeology, and sociology.

  9. States with low non-fatal injury rates have high fatality rates and vice-versa.

    Science.gov (United States)

    Mendeloff, John; Burns, Rachel

    2013-05-01

    State-level injury rates or fatality rates are sometimes used in studies of the impact of various safety programs or other state policies. How much does the metric used affect the view of relative occupational risks among U.S. states? This paper uses a measure of severe injuries (fatalities) and of less severe injuries (non-fatal injuries with days away from work, restricted work, or job transfer-DART) to examine that issue. We looked at the correlation between the average DART injury rate (from the BLS Survey of Occupational Injuries and Illnesses) and an adjusted average fatality rate (from the BLS Census of Fatal Occupational Injuries) in the construction sector for states for 2003-2005 and for 2006-2008. The RAND Human Subjects Protection Committee determined that this study was exempt from review. The correlations between the fatal and non-fatal injury rates were between -0.30 and -0.70 for all construction and for the subsector of special trade contractors. The negative correlation was much smaller between the rate of fatal falls from heights and the rate of non-fatal falls from heights. Adjusting for differences in the industry composition of the construction sector across states had minor effects on these results. Although some have suggested that fatal and non-fatal injury rates should not necessarily be positively correlated, no one has suggested that the correlation is negative, which is what we find. We know that reported non-fatal rates are influenced by workers' compensation benefits and other factors. Fatality rates appear to be a more valid measure of risk. Efforts to explain the variations that we find should be undertaken. Copyright © 2012 Wiley Periodicals, Inc.

  19. Vices, gods, and virtues: cosmology as a mediating factor in attitudes toward male homosexuality.

    Science.gov (United States)

    Hoffman, R J

    Using historical and anthropological evidence, the article examines the relationship of the polytheistic and monotheistic cosmologies and attitudes toward sexuality, in particular, male homosexuality. The polytheistic cosmology included the ideas of the continuity of creation, the generative forces of the universe as a whole, and gender blurring in the realm of the supernatural. In the monotheistic cosmology the godhead (Yahweh) is unborn and does not father any generations, the universe is desexualized, and the conception of gender is rigidified. The author concludes that polytheism created the conditions for a wide variety of sexual expression and sex-role behavior and did not preclude any particular form of sexual activity. In contradistinction, the monotheistic cosmology was highly restrictive of permissible male and female behavior and sexual expression and conduct. Consequently, polytheism was able to embrace the crossing of gender lines and homosexual relationships while monotheism was incapable of making these accommodations.

  20. Aligning the systems of environmental accounting: From EU to Stockholm and vice versa

    Energy Technology Data Exchange (ETDEWEB)

    Burstroem, F.; Frostell, B. [Royal Inst. of Technology, Stockholm (Sweden). Dept. of Environmental Technology and Work Science

    2001-07-01

    During the last decade, authorities in local and regional communities, nations and international governance organisations, like the European Union (EU), have developed several systems for environmental accounting. An important issue in this development is the collection and collation of data. Except for the question of what data to collect, there is also a question of how to collect data. Focusing in particular on developments of physical environmental accounting systems in Sweden, a member nation of the EU, and drawing from experiences from work with materials accounting in the City of Stockholm, this paper discusses the need to align environmental accounting systems of different societal levels. It is argued that the systems of collecting 'environmental' data have to be better aligned with the objectives and strategies of environmental management and policy making, taking into account all aspects of utilisation of the basic data to be collected. If not, the result will be a conservation of the fragmented point solutions of environmental accounting systems we face today, resulting in inconsistency of data, duplication of data collection and processing efforts, and inflexibility to deal with changes. From this, it is also argued that the collection of data for physical environmental accounting (i.e. data on flows and stocks of materials and substances in society and the environment), would preferably be performed by a local/regional authority, but co-ordinated by national authorities and a national statistical office, under supervision of international authorities and statistical offices. Finally, the paper presents a structural framework for regional materials accounting, which combines a product-oriented strand with a substance-oriented strand of materials accounting, and allows for accounting and analysis on different levels of aggregation. This framework, which has been developed in co-operation with the City of Stockholm, should mainly be considered as a proposal for a system of local/regional physical environmental accounting, to be used within a broader environmental management information system, but also as a proposal for a system to be used in relation to collection and collation of data in a national and even international environmental accounting system.

  1. Heavy Ion SEU Cross Section Calculation Based on Proton Experimental Data, and Vice Versa

    2014-01-01

    The aim of this work is to provide a method to calculate single event upset (SEU) cross sections by using experimental data. Valuable tools such as PROFIT and SIMPA already focus on the calculation of the proton cross section by using heavy ions cross-section experiments. However, there is no available tool that calculates heavy ion cross sections based on measured proton cross sections with no knowledge of the technology. We based our approach on the diffusion-collection model with the aim of analyzing the characteristics of transient currents that trigger SEUs. We show that experimental cross sections could be used to characterize the pulses that trigger an SEU. Experimental results allow yet defining an empirical rule to identify the transient current that are responsible for an SEU. Then, the SEU cross section can be calculated for any kind of particle and any energy with no need to know the Spice model of the cell. We applied our method to some technologies (250 nm, 90 nm and 65 nm bulk SRAMs) and we sho...

  2. Is the person-situation debate important for agent-based modeling and vice-versa?

    Directory of Open Access Journals (Sweden)

    Katarzyna Sznajd-Weron

    Full Text Available Agent-based models (ABM are believed to be a very powerful tool in the social sciences, sometimes even treated as a substitute for social experiments. When building an ABM we have to define the agents and the rules governing the artificial society. Given the complexity and our limited understanding of the human nature, we face the problem of assuming that either personal traits, the situation or both have impact on the social behavior of agents. However, as the long-standing person-situation debate in psychology shows, there is no consensus as to the underlying psychological mechanism and the important question that arises is whether the modeling assumptions we make will have a substantial influence on the simulated behavior of the system as a whole or not.Studying two variants of the same agent-based model of opinion formation, we show that the decision to choose either personal traits or the situation as the primary factor driving social interactions is of critical importance. Using Monte Carlo simulations (for Barabasi-Albert networks and analytic calculations (for a complete graph we provide evidence that assuming a person-specific response to social influence at the microscopic level generally leads to a completely different and less realistic aggregate or macroscopic behavior than an assumption of a situation-specific response; a result that has been reported by social psychologists for a range of experimental setups, but has been downplayed or ignored in the opinion dynamics literature.This sensitivity to modeling assumptions has far reaching consequences also beyond opinion dynamics, since agent-based models are becoming a popular tool among economists and policy makers and are often used as substitutes of real social experiments.

  3. Impact of B physics on model building and vice versa: An example

    We motivate that the start-up of the B factories has opened a new precision flavour physics era, with an important effect on model building. Using as an example a left-right model with spontaneous CP violation, we will show how the inclusion of the new experimental data on B physics observables, together with the old observables coming from kaon physics, has significantly widened our capacity to strongly constrain the parameter space up to the point to exclude models. On the contrary, using certain hypotheses, mainly concerning isospin, we discuss how theory may help us to 'test' the data on charged, neutral and mixed B → πK decays once experimental errors will be reduced

    We consider finite-temperature SU(2) gauge theory in the continuum formulation, which necessitates the choice of a gauge fixing. Choosing the Landau gauge, the existing gauge copies are taken into account by means of the Gribov-Zwanziger quantization scheme, which entails the introduction of a dynamical mass scale (Gribov mass) directly influencing the Green functions of the theory. Here, we determine simultaneously the Polyakov loop (vacuum expectation value) and Gribov mass in terms of temperature, by minimizing the vacuum energy w.r.t. the Polyakov-loop parameter and solving the Gribov gap equation. Inspired by the Casimir energy-style of computation, we illustrate the usage of Zeta function regularization in finite-temperature calculations. Our main result is that the Gribov mass directly feels the deconfinement transition, visible from a cusp occurring at the same temperature where the Polyakov loop becomes nonzero. In this exploratory work we mainly restrict ourselves to the original Gribov-Zwanziger quantization procedure in order to illustrate the approach and the potential direct link between the vacuum structure of the theory (dynamical mass scales) and (de)confinement. We also present a first look at the critical temperature obtained from the refined Gribov-Zwanziger approach. Finally, a particular problem for the pressure at low temperatures is reported. (orig.)

  14. Auditory Emotion Word Primes Influence Emotional Face Categorization in Children and Adults, but Not Vice Versa.

    2018-01-01

    In order to assess how the perception of audible speech and facial expressions influence one another for the perception of emotions, and how this influence might change over the course of development, we conducted two cross-modal priming experiments with three age groups of children (6-, 9-, and 12-years old), as well as college-aged adults. In Experiment 1, 74 children and 24 adult participants were tasked with categorizing photographs of emotional faces as positive or negative as quickly as possible after being primed with emotion words presented via audio in valence-congruent and valence-incongruent trials. In Experiment 2, 67 children and 24 adult participants carried out a similar categorization task, but with faces acting as visual primes, and emotion words acting as auditory targets. The results of Experiment 1 showed that participants made more errors when categorizing positive faces primed by negative words versus positive words, and that 6-year-old children are particularly sensitive to positive word primes, giving faster correct responses regardless of target valence. Meanwhile, the results of Experiment 2 did not show any congruency effects for priming by facial expressions. Thus, audible emotion words seem to exert an influence on the emotional categorization of faces, while faces do not seem to influence the categorization of emotion words in a significant way.

  15. Neuroimmune Interactions: From the Brain to the Immune System and Vice Versa.

    Dantzer, Robert

    2018-01-01

    Because of the compartmentalization of disciplines that shaped the academic landscape of biology and biomedical sciences in the past, physiological systems have long been studied in isolation from each other. This has particularly been the case for the immune system. As a consequence of its ties with pathology and microbiology, immunology as a discipline has largely grown independently of physiology. Accordingly, it has taken a long time for immunologists to accept the concept that the immune system is not self-regulated but functions in close association with the nervous system. These associations are present at different levels of organization. At the local level, there is clear evidence for the production and use of immune factors by the central nervous system and for the production and use of neuroendocrine mediators by the immune system. Short-range interactions between immune cells and peripheral nerve endings innervating immune organs allow the immune system to recruit local neuronal elements for fine tuning of the immune response. Reciprocally, immune cells and mediators play a regulatory role in the nervous system and participate in the elimination and plasticity of synapses during development as well as in synaptic plasticity at adulthood. At the whole organism level, long-range interactions between immune cells and the central nervous system allow the immune system to engage the rest of the body in the fight against infection from pathogenic microorganisms and permit the nervous system to regulate immune functioning. Alterations in communication pathways between the immune system and the nervous system can account for many pathological conditions that were initially attributed to strict organ dysfunction. This applies in particular to psychiatric disorders and several immune-mediated diseases. This review will show how our understanding of this balance between long-range and short-range interactions between the immune system and the central nervous system has evolved over time, since the first demonstrations of immune influences on brain functions. The necessary complementarity of these two modes of communication will then be discussed. Finally, a few examples will illustrate how dysfunction in these communication pathways results in what was formerly considered in psychiatry and immunology to be strict organ pathologies.

    Andriole, K

    2012-06-01

    Like Medical Physics, Imaging Informatics encompasses concepts touching every aspect of the imaging chain from image creation, acquisition, management and archival, to image processing, analysis, display and interpretation. The two disciplines are in fact quite complementary, with similar goals to improve the quality of care provided to patients using an evidence-based approach, to assure safety in the clinical and research environments, to facilitate efficiency in the workplace, and to accelerate knowledge discovery. Use-cases describing several areas of informatics activity will be given to illustrate current limitations that would benefit from medical physicist participation, and conversely areas in which informaticists may contribute to the solution. Topics to be discussed include radiation dose monitoring, process management and quality control, display technologies, business analytics techniques, and quantitative imaging. Quantitative imaging is increasingly becoming an essential part of biomedicalresearch as well as being incorporated into clinical diagnostic activities. Referring clinicians are asking for more objective information to be gleaned from the imaging tests that they order so that they may make the best clinical management decisions for their patients. Medical Physicists may be called upon to identify existing issues as well as develop, validate and implement new approaches and technologies to help move the field further toward quantitative imaging methods for the future. Biomedical imaging informatics tools and techniques such as standards, integration, data mining, cloud computing and new systems architectures, ontologies and lexicons, data visualization and navigation tools, and business analytics applications can be used to overcome some of the existing limitations. 1. Describe what is meant by Medical Imaging Informatics and understand why the medical physicist should care. 2. Identify existing limitations in information technologies with respect to Medical Physics, and conversely see how Informatics may assist the medical physicist in filling some of the current gaps in their activities. 3. Understand general informatics concepts and areas of investigation including imaging and workflow standards, systems integration, computing architectures, ontologies, data mining and business analytics, data visualization and human-computer interface tools, and the importance of quantitative imaging for the future of Medical Physics and Imaging Informatics. 4. Become familiar with on-going efforts to address current challenges facing future research into and clinical implementation of quantitative imaging applications. © 2012 American Association of Physicists in Medicine.

  1. Government regulation of gambling advertising: Replacing vice prevention with consumer protection.

    Science.gov (United States)

    Rothman, M; Robbins, H

    1991-12-01

    From 1895 to 1975, federal law forbade gambling advertising by use of the mail, interstate commerce, and the broadcast media. Congress exempted state lotteries in 1975 and charitable gambling (including casino games) in 1988. However, the Supreme Court requires a significant government interest, directly applied and narrowly tailored, in order to justify a commercial speech regulation. The exemptions for private charity casino games has arguably destroyed any constitutionally defensible government interest in restricting for-profit casinos. Casinos in new gambling jurisdictions (such as Iowa or Illinois) will probably push the hardest for an exemption for all legal gambling, as they have the most to gain from the freedom to advertise. Federal regulation of gambling advertising will fall to the Federal Trade Commission under prohibitions against "unfair or deceptive" trade practices. But as State regulations are not well developed even in states that permit casino gambling, there is a pressing need for new research to review state laws regulating gambling advertising and to propose a model statute.

  2. Developmental cognitive genetics: How psychology can inform genetics and vice versa

    Bishop, Dorothy V. M.

    2006-01-01

    Developmental neuropsychology is concerned with uncovering the underlying basis of developmental disorders such as specific language impairment (SLI), developmental dyslexia, and autistic disorder. Twin and family studies indicate that genetic influences play an important part in the aetiology of all of these disorders, yet progress in identifying genes has been slow. One way forward is to cut loose from conventional clinical criteria for diagnosing disorders and to focus instead on measures of underlying cognitive mechanisms. Psychology can inform genetics by clarifying what the key dimensions are for heritable phenotypes. However, it is not a one-way street. By using genetically informative designs, one can gain insights about causal relationships between different cognitive deficits. For instance, it has been suggested that low-level auditory deficits cause phonological problems in SLI. However, a twin study showed that, although both types of deficit occur in SLI, they have quite different origins, with environmental factors more important for auditory deficit, and genes more important for deficient phonological short-term memory. Another study found that morphosyntactic deficits in SLI are also highly heritable, but have different genetic origins from impairments of phonological short-term memory. A genetic perspective shows that a search for the underlying cause of developmental disorders may be misguided, because they are complex and heterogeneous and are associated with multiple risk factors that only cause serious disability when they occur in combination.

  3. Friends with Faces: How Social Networks Can Enhance Face Recognition and Vice Versa

    Science.gov (United States)

    Mavridis, Nikolaos; Kazmi, Wajahat; Toulis, Panos

    The "friendship" relation, a social relation among individuals, is one of the primary relations modeled in some of the world's largest online social networking sites, such as "FaceBook." On the other hand, the "co-occurrence" relation, as a relation among faces appearing in pictures, is one that is easily detectable using modern face detection techniques. These two relations, though appearing in different realms (social vs. visual sensory), have a strong correlation: faces that co-occur in photos often belong to individuals who are friends. Using real-world data gathered from "Facebook," which were gathered as part of the "FaceBots" project, the world's first physical face-recognizing and conversing robot that can utilize and publish information on "Facebook" was established. We present here methods as well as results for utilizing this correlation in both directions. Both algorithms for utilizing knowledge of the social context for faster and better face recognition are given, as well as algorithms for estimating the friendship network of a number of individuals given photos containing their faces. The results are quite encouraging. In the primary example, doubling of the recognition accuracy as well as a sixfold improvement in speed is demonstrated. Various improvements, interesting statistics, as well as an empirical investigation leading to predictions of scalability to much bigger data sets are discussed.

    Directory of Open Access Journals (Sweden)

    Michal Banaszak

    Full Text Available This study offers a new perspective on the evolutionary patterns of cities or urban agglomerations. Such developments can range from chaotic to fully ordered. We demonstrate that in a dynamic space of interactive human behaviour cities produce a wealth of gravitational attractors whose size and shape depend on the resistance of space emerging inter alia from transport friction costs. This finding offers original insights into the complex evolution of spatial systems and appears to be consistent with the principles of central place theory known from the spatial sciences and geography. Our approach is dynamic in nature and forms a generalisation of hierarchical principles in geographic space.

  10. Locomotion, Energetics, Performance, and Behavior: A Mammalian Perspective on Lizards, and Vice Versa.

    Science.gov (United States)

    Garland, Theodore; Albuquerque, Ralph L

    2017-08-01

    Animals are constrained by their abilities and by interactions with environmental factors, such as low ambient temperatures. These constraints range from physical impossibilities to energetic inefficiencies, and may entail trade-offs. Some of the constraints related to locomotion and activity metabolism can be illustrated through allometric comparisons of mammals and lizards, as representative terrestrial vertebrate endotherms and ectotherms, respectively, because these lineages differ greatly in aerobic metabolic capacities, resting energetic costs, and thermoregulatory patterns. Allometric comparisons are both useful and unavoidable, but "outlier" species (unusual for their clade) can also inform evolutionary scenarios, as they help indicate extremes of possible adaptation within mammalian and saurian levels of organization. We compared mammals and lizards for standard metabolic rate (SMR), maximal oxygen consumption during forced exercise (VO2max), net (incremental) cost of transport (NCT), maximal aerobic speed (MAS), daily movement distance (DMD), daily energy expenditure (DEE) during the active season, and the ecological cost of transport (ECT = percentage of DEE attributable to locomotion). (Snakes were excluded because their limbless locomotion has no counterpart in terrestrial mammals.) We only considered lizard SMR, VO2max, NCT, MAS, and sprint speed data if measured at 35-40 °C. On average, MAS is ∼7.4-fold higher in mammals, whereas SMR and VO2max are ∼6-fold greater, but values for all three of these traits overlap (or almost overlap) between mammals and lizards, a fact that has not previously been appreciated. Previous studies show that sprint speeds are similar for smaller mammals and lizards, but at larger sizes lizards are not as fast as some mammals. Mammals move ∼6-fold further each day than lizards, and DMD is by far the most variable trait considered here, but their NCT is similar. Mammals exceed lizards by ∼11.4-fold for DEE. On average for both lineages, the ECT is surprisingly low, somewhat higher for lizards, and positively allometric. If a lizard and mammal of 100 g body mass were both to move their entire DMD at their MAS, they could do so in ∼21 and 17 min, respectively, thus de-emphasizing the possible importance of time constraints. We conclude that ecological-energetic constraints related to locomotion are relatively more likely to occur in large, carnivorous lizards. Overall, our comparisons support the idea that the (gradual) evolution of mammalian endothermy did not necessarily require major changes in locomotor energetics, performance, or associated behaviors. Instead, we speculate that the evolution of thermoregulatory responses to low temperatures (e.g., shivering) may have been a key and "difficult" step in this transition. © The Author 2017.

  11. Vice and virtue in regulating the disposal of high level nuclear waste

    International Nuclear Information System (INIS)

    Fleming, P.A.

    1999-01-01

    The disagreement over whether standards governing radioactive release should be general, internationally acceptable principles or site specific, contextualized standards reminds the ethicist of the deep disagreement between egalitarian and utilitarian ideals. One should set criteria for health and environment standards that would be acceptable to all rational agents, despite the contexts of needs and desires within which the agents are enmeshed. Remove the veil which masks the moral agent and were she to discover herself to be a subset critical-group member (e.g. a pregnant woman living in Armagosa Valley, Nevada), she would nevertheless find the standards acceptable. This egalitarianism is further justified by the belief that it is morally impermissible not to respect every human being, oneself or any other, as a rational creature. Site-specific standards are viewed with askance in the belief that regulations tailored to specific situations will more likely than not result in political opportunism, i.e. treating some human beings with inequity. But, one need only cite the difficulties of the egalitarian position to provide the human community with practical solutions to easily see why one might think that the utilitarian view supports site-specific standards. Appealing to the John Stuart Mill's principle of utility, whereby one's moral obligation is to achieve the greater overall good, regulators who seek to create these standards are freed from the moral constraints imposed by the pure rational agent. Impure reasoning, which attends to context, is not only permissible, it is desirable and even obligatory. Regulators are motivated by pragmatic considerations, which morally legitimate the imposition of risks on a small number for the benefit of the overall good. Site specific standards infused with utility get a needed job done and that is good enough

    space in the modern age, just as the elements that make ease the rise of totalitarianism, Hannah Arendt analyses the relations of the bourgeoisie, the mob and the masses with the public realm. My aim in this paper is to explain, according Hannah Arendt, in which extent the intrusion in the public space of concerns from private space may results in a debilitation of political realm before the attacks against it.Hannah Arendt, na sua busca por identificar as razões do declínio
    do espaço público na época moderna e os elementos que contribuíram para facilitar a ascensão do totalitarismo, examina a relação da burguesia, da ralé e das massas com o domínio público. O que buscarei explicitar neste artigo, seguindo a argumentação da pensadora, é o quanto a invasão do espaço público por preocupações provenientes da esfera privada pode redundar em um enfraquecimento do domínio político, ante os ataques que lhe são desferidos.

  16. Robotic influence in the conceptual design of mechanical systems in space and vice versa - A survey

    Sanger, George F.

    1988-01-01

    A survey of methods using robotic devices to construct structural elements in space is presented. Two approaches to robotic construction are considered: one in which the structural elements are designed using conventional aerospace techniques which tend to constrain the function aspects of robotics and one in which the structural elements are designed from the conceptual stage with built-in robotic features. Examples are presented of structural building concepts using robotics, including the construction of the SP-100 nuclear reactor power system, a multimirror large aperture IR space telescope concept, retrieval and repair in space, and the Flight Telerobotic Servicer.

  17. Vice President of Medical Affairs--moving on up to CEO?

    Increasingly, physician executives are reaching the conclusion that if they choose, they may be viable candidates for CEO positions. While this opinion has merit, it must be tempered by marketplace realities. A fundamental issue for VPMAs aspiring to become CEOs is that they have little formalized training or education for CEO roles. Also, they may lack team-building skills--a critical success factor. Physician executives who seek out professional development opportunities that enhance both their interpersonal/management and "business" skills--accounting, finance, and planning--are more likely to be attractive candidates and succeed once they are in the position. Another consideration is that the CEO position usually has a precursor role--the COO. This position is the training ground for the CEO. Physician executives aspiring to be CEO will want to consider the following suggestions: (1) Make your intentions known; (2) groom your successor; (3) request a title change; (4) get your master's degree; (5) pursue professional development opportunities; (6) consider leaving the organization; and (7) talk with your family.

    Many scholars have stressed the need for balancing exploitation with sufficient levels of exploration (Levinthal and March, 1993; March, 1991, 2006). Organizations that have a one-sided focus on exploitation by allocating resources to refinement of existing technologies rather than to developing new

  19. The effect of sediment transport on eelgrass development – and vice versa

    By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development.
