More time for complex consultations in a high deprivation practice is associated with increased patient enablement
No full textBackgroundEvidence of the beneficial effects of longer consultations in general practice is limited.AimTo evaluate the effect of increasing consultation length on patient enablement in general practice in an area of extreme socioeconomic deprivation.Design of studyLongitudinal study using a ‘before and after’ design.SettingKeppoch Medical Centre in Glasgow, which serves the most deprived practice area in Scotland.MethodParticipants were 300 adult patients at baseline, before the introduction of longer consultations, and 324 at follow-up, more than 1 year after the introduction of longer consultations. The intervention studied was more time in complex consultations. Patient satisfaction, perceptions of the GPs’ empathy, GP stress, and patient enablement were collected by faceto-face interview. Additional qualitative data were obtained by individual interviews with the GPs, relating to their perceptions of the impact of the longer consultations.ResultsResponse rates of 70% were obtained. Overall, 53% of consultations were complex. GP stress was higher in complex consultations. Patient satisfaction and perception of the GPs’ empathy were consistently high. Average consultation length in complex consultations was increased by 2.5 minutes by the intervention. GP stress in consultations was decreased after the introduction of longer consultations, and patient enablement was increased. GPs’ views endorsed these findings, with more anticipatory and coordinated care being possible in the longer consultations.ConclusionMore resource to provide more time in complex consultations in an area of extreme deprivation is associated with an increase in patient enablement

Three-component velocity measurements in a momentum-conserving, axisymmetric, turbulent jet
No full textExperiments have been performed on a momentum conserving axisymmetric turbulent jet, the turbulence characteristics of which are well known [1]. Simultaneous three-component velocity measurements are acquired with high spatial and temporal resolution, using a new triple-sensor hotwire probe. Velocity and directional calibrations are performed using a dedicated automatic calibration system. Two experiments are performed; one for capturing the average velocity field in a 3D volume, and one for investigating the turbulence spectra in specific points in space. In the first experiment, measurements are performed in 9 equidistant cross-planes, from 10- to 50-diameters downstream of the nozzle using a computer-controlled traversing system. The spatial resolution is as low as 1 mm and the sampling rate was 10 kHz. In the second experiment, long velocity time histories are acquired with 50 kHz sampling rate to perform power spectral density computations for each velocity component. Preliminary results of velocity capture confirm the general characteristics of the turbulent jet. The power spectra at different positions indicate that the turbulent fluctuations are not isotropic at lower frequencies
A General History of the Congregation of the Mission Beginning after the Death of Blessed Vincent de Paul
No full textThis work is the earliest known history of the Congregation of the Mission and dates from about 1730. Vincentian historian John E. Rybolt, C.M., building on the initiative of Stafford Poole, C.M., completed this English translation from the original French. The author, Claude-Joseph Lacour, C.M. (1672-1731), drew from already published materials and his own recollections. While the story he tells may seem familiar, Lacour included materials that are unknown anywhere else and delivers a first-hand account of the Congregation’s rapid growth in those early days. The text is essential reading for anyone wishing to better understand Vincent de Paul’s society of apostolic life of priests and brothers following his death.https://via.library.depaul.edu/vincentian_ebooks/1044/thumbnail.jp
Turbulent separation in lower curved wall channels
No full textTurbulent boundary layer separation in channels with a lower curved wall is studied using direct numerical simulations (DNS). Turbulence dynamics are studied through classical statistical tools such as the turbulent kinetic energy budget for varying lower curved wall dimensions. The geometry features are expected to have a significant effect on the fluid flow structures and the characteristic scales of separation. The separation bubble behind the bump is studied in terms of its size, turbulent kinetic energy production mechanisms and transfer and scale-by-scale energy budget. New innovative data-analysis techniques will be used based on the generalisation of the Kolmogorov equation to anisotropic and spatially non-homogeneous flow configurations
Turbulence modulation in particle laden homogeneous shear flow: Exact Regularized Point Particle method
No full textThis contribution presents a first evaluation of a new approach, dubbed the Exact Regularized Point Particle (ERPP) method [Gualtieri et al., Exact regularized point particle method for multi-phase flows in the two-way coupling regime, arXiv preprint arXiv:1405.6969], designed to model the modulation of turbulence by hundred thousands of small inertial particles. The approach overcomes some intrinsic difficulties which arise in some circumstances in available approaches like, e.g., the Particle In Cell (PIC) method introduced by Crowe and coworkers since 1977. Numerical results concerning a homogeneous shear flow at moderate values of the Reynolds number laden with hundred thousand of small inertial particles are discussed documenting the turbulence modification in the so-called two-way coupling regime, in a range of control parameters unaccessible to the available approaches
The great household in late medieval England
No full textIn the later medieval centuries, a whole range of important social, political, and artistic activities took place against the backdrop of the great English households. In this lively book, C. M. Woolgar explores the fascinating details of life in a great house. Based on extensive investigation of household accounts and related primary documents, Woolgar vividly illuminates the operations of great households. He also delineates the major changes that transformed the economy and geography of both lay and clerical households between 1200 and 1500.In this portrait of aristocratic and gentry life in medieval England, Woolgar describes the roles of family members, the situations of servants, the uses of space within the household, food and drink for daily consumption and for special occasions, furnishing, clothing, arrangements for travel, household animals, cleanliness and hygiene, entertainment, the practices of religion, and intellectual life. The author also analyzes the qualitative and social evolution of great households as definitions of magnificence and conventions of etiquette became increasingly elaborate
Switch from alpha v beta 5 to alpha v beta 6 integrin expression protects squamous cell carcinomas from anoikis
No full textStratified squamous epithelia express the alphavbeta5 integrin, but in squamous cell carcinomas (SCCs) there is down-regulation of alphavbeta5 and up-regulation of alphavbeta6. To investigate the significance of this finding, we transduced an alphav-negative human SCC line with retroviral vectors encoding alphav integrins. alphavbeta5-expressing cells underwent suspension-induced apoptosis (anoikis), whereas alpha-negative cells and cells expressing alphavbeta6 did not. Resistance to anoikis correlated with PKB/Akt activation in suspension, but not with changes in PTEN or p110alpha P13 kinase levels

Safety test of an improved multihundred watt FSA: launch abort, solid propellant fire
No full textThis safety test consisted of exposing a simulant-fueled Improved Multihundred Watt Fuel Sphere Assembly, containing a Pt-3008 sphere holding the fuel simulant, to a single proximity fire of UTP-3001 solid rocket propellant for 10.5 min. The graphite outside shell sustained only minor abrasion damage. It was covered on one side with a heavy deposit of alumina from the fire mixed with silica from the test bed. The Pt-3008 shell had small amounts of carbon, alumina, and silica deposited on its surface but sustained no other damage. The PT-3008 sphere was not breached, and therefore the fuel sphere assembly would not release fuel in a solid-propellant fire of a launch abort. 12 figures
Turbulence modulation in particle laden pipe flow: Exact regularized point particle method
No full textMany technological applications are characterized by turbulent bounded flows with dispersed particles. For high mass load (particle/fluid mass ratio) a significant inter-phase momentum exchange occurs (two-way coupling regime), inducing a significant alteration of the turbulent field which, in turn, modifies the dynamics of the suspended phase. Aim of the present study is exploring the potentially of recently developed momentum coupling method, dubbed the Exact Regularized Point Particle (ERPP) method, in reproducing via Direct Numerical Simulation (DNS) the detailed dynamics of a particles laden turbulent pipe flow. The comparison with available experimental and numerical data confirms the ability of the new approach in reproducing the relevant dynamics also in parameter ranges which are unaccessible to standard techniques
