Antigüedad clásica y cultura nobiliaria en la España de finales del siglo XVIII. Autores y ediciones greco-romanas en la biblioteca de José Alvarez d…

2019

This article analyzes the reception of the classical world in the Spanish nobiliary culture at the end of the 18th century. Our objective is materialized through the study of the Greco-Roman books present in the unpublished catalog of the library of José Álvarez de Toledo, 11th Marqués de villafranca. From the examination of the authors and the different editions conserved by the aristocrat, the work tries to examine the influence of the classical world and its actuality in the development of the most advanced nobiliary culture of eighteenth- century Spain.

Integration of a Dirac comb and the Bernoulli polynomials

2016

Abstract For any positive integer n , we consider the ordinary differential equations of the form y ( n ) = 1 − Ш + F where Ш denotes the Dirac comb distribution and F is a piecewise- C ∞ periodic function with null average integral. We prove the existence and uniqueness of periodic solutions of maximal regularity. Above all, these solutions are given by means of finite explicit formulae involving a minimal number of Bernoulli polynomials. We generalize this approach to a larger class of differential equations for which the computation of periodic solutions is also sharp, finite and effective.

Test-retest reliability of a new self reported comprehensive questionnaire measuring frequencies of different modes of adolescents commuting to schoo…

Published version of an article from the journal: International Journal of Behavioral Nutrition and Physical Activity Article available from: http://www.ijbnpa.org/content/6/1/68 Background: Studies assessing active commuting to school usually use simple questionnaires, and often is mode of commuting reported with a single questionnaire item only. The purpose of the present study is to report the test-retest reliability of a newly developed comprehensive questionnaire on active commuting to school and work among 6thgrade school children and their parents in Norway. Methods: A total of 106 pupils and 77 parents completed a questionnaire two times, 14 days apart. The questionnaire consisted o…

A Derivation of the Vlasov-Stokes System for Aerosol Flows from the Kinetic Theory of Binary Gas Mixtures

2016

In this short paper, we formally derive the thin spray equation for a steady Stokes gas, i.e. the equation consists in a coupling between a kinetic (Vlasov type) equation for the dispersed phase and a (steady) Stokes equation for the gas. Our starting point is a system of Boltzmann equations for a binary gas mixture. The derivation follows the procedure already outlined in [Bernard-Desvillettes-Golse-Ricci, arXiv:1608.00422 [math.AP]] where the evolution of the gas is governed by the Navier-Stokes equation.

Traditional and professional birth attendants influence on womens decisions of birth place and type of birth assistance : a qualitative study in Tang…

2012

Author's version of an article in the journal: Nordisk Sygeplejeforskning. Also available from the publisher at: http://www.idunn.no/ts/nsf/2012/01/art02 Almost half of all Tanzanian women deliver at home, alone, assisted by family members or traditional birth attendants. The aim of this article was to expand existing knowledge on how pregnant and laboring women's preferences and decisions of birth place and type of assistance are influenced. A qualitative study with semi-structured interviews, with two traditional birth attendants and one midwife, and a participatory observation was conducted at a health clinic in Tanga District, Tanzania. It was found that the interaction between pregnant…

Do we need to change the guideline values for determining low bone mineral density in athletes? [Viewpoint]

Large segmental bone defects occurring after trauma, bone tumors, infections or revision surgeries are a challenge for surgeons. The aim of our study was to develop a new biomaterial utilizing simple and cheap 3D-printing techniques. A porous polylactide (PLA) cylinder was printed and functionalized with stromal-derived factor 1 (SDF-1) or bone morphogenetic protein 7 (BMP-7) immobilized in collagen type I. Biomechanical testing proved biomechanical stability and the scaffolds were implanted into a 6 mm critical size defect in rat femur. Bone growth was observed via x-ray and after 8 weeks, bone regeneration was analyzed with µCT and histological staining methods. Development of non-unions …

Effect of female genital schistosomiasis and anti-schistosomal treatment on monocytes, CD4+ T-cells and CCR5 expression in the female genital tract

2014

Published version of an article from the journal: PLoS One. Also available from the publisher: http://dx.doi.org/10.1371/journal.pone.0098593 BACKGROUND: Schistosoma haematobium is a waterborne parasite that may cause female genital schistosomiasis (FGS), characterized by genital mucosal lesions. There is clinical and epidemiological evidence for a relationship between FGS and HIV. We investigated the impact of FGS on HIV target cell density and expression of the HIV co-receptor CCR5 in blood and cervical cytobrush samples. Furthermore we evaluated the effect of anti-schistosomal treatment on these cell populations. DESIGN: The study followed a case-control design with post treatment follow…
