Thomas-Fermi theory for atomic nuclei revisited

The recently developed semiclassical variational Wigner-Kirkwood (VWK) approach is applied to finite nuclei using external potentials and self-consistent mean fields derived from Skyrme inter-actions and from relativistic mean field theory. VWK consist s of the Thomas-Fermi part plus a pure, perturbative h 2 correction. In external potentials, VWK passes through the average of the quantal values of the accumulated level density and total en energy as a function of the Fermi energy. However, there is a problem of overbinding when the energy per particle is displayed as a function of the particle number. The situation is analyzed comparing spherical and deformed harmonic oscillator potentials. In the self-consistent case, we show for Skyrme forces that VWK binding energies are very close to those obtained from extended Thomas-Fermi functionals of h 4 order, pointing to the rapid convergence of the VWK theory. This satisfying result, however, does not cure the overbinding problem, i.e., the semiclassical energies show more binding than they should. This feature is more pronounced in the case of Skyrme forces than with the relativistic mean field approach. However, even in the latter case the shell correction energy for e.g.208 Pb turns out to be only ∼ −6 MeV what is about a factor two or three off the generally accepted value. As an adhoc remedy, increasing the kinetic energy by 2.5%, leads to shell correction energies well acceptable throughout the periodic table. The general importance of the present studies for other finite Fermi systems, self-bound or in external potentials, is pointed out.

Managing the Sick Child in the Era of Declining Malaria Transmission: Development of ALMANACH, an Electronic Algorithm for Appropriate Use of Antimicrobials.

OBJECTIVE: To review the available knowledge on epidemiology and diagnoses of acute infections in children aged 2 to 59 months in primary care setting and develop an electronic algorithm for the Integrated Management of Childhood Illness to reach optimal clinical outcome and rational use of medicines. METHODS: A structured literature review in Medline, Embase and the Cochrane Database of Systematic Review (CDRS) looked for available estimations of diseases prevalence in outpatients aged 2-59 months, and for available evidence on i) accuracy of clinical predictors, and ii) performance of point-of-care tests for targeted diseases. A new algorithm for the management of childhood illness (ALMANACH) was designed based on evidence retrieved and results of a study on etiologies of fever in Tanzanian children outpatients. FINDINGS: The major changes in ALMANACH compared to IMCI (2008 version) are the following: i) assessment of 10 danger signs, ii) classification of non-severe children into febrile and non-febrile illness, the latter receiving no antibiotics, iii) classification of pneumonia based on a respiratory rate threshold of 50 assessed twice for febrile children 12-59 months; iv) malaria rapid diagnostic test performed for all febrile children. In the absence of identified source of fever at the end of the assessment, v) urine dipstick performed for febrile children <2 years to consider urinary tract infection, vi) classification of 'possible typhoid' for febrile children >2 years with abdominal tenderness; and lastly vii) classification of 'likely viral infection' in case of negative results. CONCLUSION: This smartphone-run algorithm based on new evidence and two point-of-care tests should improve the quality of care of <5 year children and lead to more rational use of antimicrobials.

Genetic polymorphisms in the Cytochrome P450 family and squamous cell carcinoma of the oral cavity, pharynx and larynx

Objective:To analyze the genetic polymorphisms of the cytochrome P450 family and their relationship with squamous cell carcinoma of the oral cavity, pharynx and larynx.Methods: We present a narrative literature review, conducted in Pubmed, Lilacs and Cochrane Databases of articles published in the last five years correlating genetic polymorphisms of the cytochrome P450 family and cancer risk in different populations worldwide.Results: We initially found 65 articles and, after selection criteria, 20 case-control studies with various populations worldwide were eligible. The most studied polymorphisms were those of CYP2E1 and CYP1A1 subfamilies. There is little about the other subfamilies. The association found between polymorphisms and cancer risk amounted to a countless number of variables, amongst them: population, selection methods, racial factors and different modes of exposure to carcinogens, genotyping methods, and nomenclature of the polymorphisms.Conclusion: so far, there is no proven link between genetic polymorphisms of cytochrome P450 family and squamous cell carcinoma of the oral cavity, pharynx and larynx relationship.

"Monseigneur, pardonnez-moi parce que j'ai péché" : la régulation de la dissidence au sein du clergé canadien, au moment de l'invasion américaine de 1775-1776

Cet ouvrage porte sur la réaction du clergé canadien face à l’invasion américaine de 1775-1776. Alors que l’historiographie considère généralement que les prêtres de la colonie restèrent fidèles au gouvernement britannique à cette occasion, trois curés se détachèrent au contraire de cette image de loyalisme : Eustache Chartier de Lotbinière (1716-1785), Pierre-René Floquet (1716-1782) ainsi que Pierre Huet de La Valinière (1732-1806). Soupçonnés par les autorités ecclésiastiques et coloniales d’entrenir des sympathies pour les révolutionnaires américains, ces hommes furent frappés par diverses sanctions, affectant durablement le déroulement de leur carrière.

Les fonctions théoriques de la notion d’acte d’être (actus essendi) chez Thomas d’Aquin

Nous entendons, dans ce mémoire, préciser le sens d'actus essendi par l’analyse de l’emploi du terme par Thomas d’Aquin. Bien que la notion d’acte d’être soit sousjacente à nombre de développements philosophiques et théologiques de l’Aquinate, elle n’est considérée pour elle-même dans aucun texte du corpus thomasien. En exposant le cadre théorique des onze unités textuelles dans lesquelles on retrouve nommément l’expression, nous explicitons les distinctions qu’opère Thomas entre l’acte d’être et les notions ontologiques corrélatives (étant, quiddité, être du jugement prédicatif et être commun). Si « actus essendi » désigne en premier lieu un principe constitutif de l’étant, il peut encore désigner le terme abstrait correspondant à cette perfection de l’étant. L’acte d’être est ainsi ce par quoi l’étant est étant; il est cependant, au plan ontologique, propre à chaque étant singulier tandis que, au plan conceptuel, le même terme exprime ce qui est commun à tous les étants. Une traduction des extraits du Scriptum super Sententiis, des Quæstiones de quolibet, de la Summa Theologiæ, des Quæstiones disputatæ De potentia, de l’Expositio libri De hebdomadibus et de la Expositio libri Metaphysicæ a été produite pour les fins de cette étude.
