Rocking of rigid block on nonlinear flexible foundation

2017

Abstract The two prime models used currently to describe rocking of rigid bodies, the Housner’s model and the Winkler foundation model, can capture some of the salient features of the physics of this important problem. These two models involve either null or linear interaction between the block and the foundation. Hopefully, some additional aspects of the problem can be captured by an enhanced nonlinear model for the base-foundation interaction. In this regard, what it is adopted in this paper is the Hunt and Crossley’s nonlinear impact force model in which the impact/contact force is represented by springs in parallel with nonlinear dampers. In this regard, a proper mathematical formulatio…

On stability of linear dynamic systems with hysteresis feedback

2020

The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure's problem) can be proved by the well-known circle criterion, the multivalued rate-independent hysteresis poses significant challenges for feedback systems, especially for proof of convergence to an equilibrium state correspondingly set. The dissipative behavior of clockwise input-output hysteresis is considered with two boundary cases of energy losses at reversal cycles. For upper boundary cases of maximal (parallelogram shape) hysteresis loop, an equivalent transformation of the closed-loop system is provided. This allows for the appli…

Rodzinna postpamięć Ślązaków

2017

Family Postmemory of the People of Silesia
 The author suggests a possible use of postmemory to analyse the contemporary family memory of the people of Silesia. Their memoirs about WW2 (such as working for the Wehrmacht, the Red Army invading Silesia, working in labour camps, nationality verification, displacements to Germany, and deportations to Siberia) bear signs of latent memory which is rarely revealed even to the next of kin. Present mainly within the family circle, within the local society, and among friends, these memoirs integrated Silesians and made them a unique community that considers itself a stigmatized minority. This contributed to mythologizing and stereotyping the who…

From “Mano Dura” to “Enfrentamiento Directo”: swings of public policies in El Salvador

2019

RESUMEN Introduccion: El presente trabajo analiza las cuatro principales politicas publicas de seguridad contra las pandillas en El Salvador: Mano Dura (2003-2004), Super Mano Dura (2004-2009), Tregua entre pandillas (2012-2014) y Enfrentamiento Directo (2014-2019). El objetivo es identificar la influencia de estas politicas sobre la violencia. Materiales y Metodos: Se trata de una investigacion cualitativa apoyada en 12 entrevistas y el relato de vida con las que se explora la responsabilidad gubernamental frente al problema de la violencia en El Salvador. El trabajo de campo se efectuo durante 7 meses, entre septiembre de 2016 y marzo de 2017. El tratamiento de la informacion se efectuo m…

Essais cliniques institutionnels : quel monitoring ?

2013

Resume Objectif Les promoteurs assument la responsabilite de la qualite des essais cliniques. Ces methodes d’assurance qualite doivent etre les plus efficaces possible, et avoir un cout maitrise. Nous voulions decrire les erreurs les plus frequentes, a partir de la litterature, leur impact sur les resultats, et proposer les strategies de monitoring les plus efficientes. Resultats Les defauts rencontres concernent la conception, les procedures, la gestion des donnees et l’analyse. L’impact sur les resultats est presque toujours une surestimation de l’effet traitement. Aucune methode de monitoring n’ayant ete demontree superieure, un monitoring econome, cible sur les risques d’erreurs, avec d…

Manuel de bonnes pratiques professionnelles des centres d’investigation clinique

2012

Resume Les centres d’investigation clinique (CIC) sont des structures de recherche clinique academiques appartenant a un reseau national, coordonne par l’Institut national de la sante et de la recherche medicale (Inserm) et la Direction generale de l’offre de soins (DGOS), comportant des groupes de travail et des reseaux thematiques. Le groupe « Harmonisation des procedures des CIC » (HPCIC) a elabore un manuel de bonnes pratiques professionnelles, presente dans cet article. Le manuel a ete elabore par consensus, relu par les coordonnateurs des CIC, des experts externes, et valide par des representants des deux tutelles Inserm et DGOS. Le manuel de bonnes pratiques professionnelles des CIC …

Triglicéridos, colesterol HDL y dislipidemia aterogénica en la guía europea para el control de las dislipidemias 2019

2020

En general, las guías de práctica clínica tanto europeas con americanas han abordado el control de la dislipidemia aterogénica de forma poco convincente e incluso superficial, en gran medida por las limitaciones terapéuticas disponibles. En consecuencia, esta dislipidemia está infradiagnosticada, infratratada e infracontrolada. Dada la reciente aparición de la guía 2019 de la European Atherosclerosis Society y de la European Society of Cardiology sobre el control de las dislipidemias, parece oportuno examinar su posicionamiento con respecto a la dislipidemia aterogénica y/o sus principales componentes, el aumento en las lipoproteínas ricas en triglicéridos y la disminución del colesterol de…

Riesgo cardiovascular residual de origen lipídico. Componentes y aspectos fisiopatológicos

2019

Resumen Es indudable la relacion del cLDL y el riesgo cardiovascular, asi como de los beneficios del tratamiento con estatinas. Una vez conseguido el objetivo de cLDL, son notables las evidencias que demuestran la persistencia de un elevado riesgo cardiovascular, concepto denominado riesgo residual. El riesgo residual de origen lipidico se fundamenta en la dislipidemia aterogenica, caracterizada por un aumento de trigliceridos y de las lipoproteinas ricas en trigliceridos, un descenso del cHDL y alteraciones cualitativas de las particulas LDL. Las medidas mas utilizadas para identificar esta dislipidemia se basan en la determinacion de colesterol total, trigliceridos, HDL, colesterol no HDL…
