Family history and adoption in the UK: conflicts of interest in medical disclosure
No full textRadical Intervention: Every year, around 4000 children are adopted from public care in the UK.1 Adoption is “one of the most radical interventions to make in the life of a child”2 as it legally terminates the child’s relationship with their birth family. Adoption medical advisors (the usual title for doctors, generally paediatricians, who work with adoption agencies) play an important role in collating and interpreting the child’s medical and developmental history which is then shared with prospective adopters. A key part of this history is a child’s family medical history. Contemporary adoption practice encourages frank disclosure of such medical information to prospective adoptive parents. Indeed, the Adoption Act Regulations 2005 state that: “The adoption agency must obtain, so far as is reasonably practicable, the information about the health of each of the child’s natural parents and his brothers and sisters (of the full blood or half-blood)”. Adoption medical advisors are privy to information about birth parents’ medical history through a variety of sources but do not always have consent to share this.3 A tension between preserving birth parents’ right to confidentiality – especially when they have specifically indicated they do not wish to share their medical information – and a child’s interest in knowing such information about their parents – because it might have relevance to their own future – therefore needs to be negotiated. If medical information is not shared at this point, the adopted child may experience a lifetime of ignorance about their family health history and possible future health risks. Using fictitious cases based on clinical practice this article highlights the tensions about information sharing in adoption practice, reviews current professional guidelines and legislation, and suggests possible solutions. <br/
Algebraic Quantum Mechanics and Pregeometry
No full textWe discuss the relation between the q-number approach to quantum mechanics suggested by Dirac and the notion of "pregeometry" introduced by Wheeler. By associating the q-numbers with the elements of an algebra and regarding the primitive idempotents as "generalized points" we suggest an approach that may make it possible to dispense with an a priori given space manifold. In this approach the algebra itself would carry the symmetries of translation, rotation, etc. Our suggestion is illustrated in a preliminary way by using a particular generalized Clifford algebra proposed originally by Weyl, which approaches the ordinary Heisenberg algebra a suitable limit. We thus obtain a certain insight into how quantum mechanics may be regarded as a purely algebraic theory, provided that we further introduce a new set of "neighbourhood operators", which remove an important kind of arbitrariness that has thus far been present in the attempt to treat quantum mechanics solely in terms of a Heisenberg algebra

Vascular endothelial growth factor and placental growth factor release in cultured trophoblast cells under different oxygen tensions
No full textThe oxygen status of the placenta during pregnancy is unclear although it has been hypothesised that in pre-eclampsia large regions of the placenta are hypoxic. Circulating levels of vascular endothelial growth factor (VEGF) are increased in women with pre-eclampsia, while circulating placental growth factor (PlGF) levels are decreased. We hypothesise that secreted levels of VEGF are increased in cultures of trophoblast cells under lowered oxygen conditions while secreted levels of PlGF are alternatively regulated. Primary isolates of first trimester and term cytotrophoblasts cells were cultured in 20 and 5% oxygen for 24 h. There was a significant increase in the levels of VEGF secreted from first trimester and term cytotrophoblast cells cultured under lowered oxygen conditions compared to the controls while there was a significant decrease in the secreted levels of PlGF in the same cell populations (as measured by ELISA). In first trimester and term trophoblast cells the presence of VEGF (121, 165 and 189) and PlGF (132 and 152) mRNA were demonstrated in both groups by reverse transcription-polymerase chain reaction (RT-PCR). These altered levels of secreted VEGF and PlGF may be released as compensatory molecules in the pathogenesis of diseases such as pre-eclampsia and intrauterine growth restriction
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
