Static instability analysis of an elastic band travelling in the gravitational field
2011
Static instability analysis is performed for an axially moving elastic band, which is travelling at a constant velocity in a uniform gravitational field between two supports. The buckling of the band is investigated with the help of admitting small transverse deflections. The model of a thin elastic beam (panel) subjected to bending, centrifugal forces and nonhomogeneous tension (including a gravitational term) is used. Buckling analysis and estimation of the critical velocities of elastic instability are based on variational principles and variational inequalities. As a result, explicit formulas for upper and lower limits for critical velocities are found. It is shown analytically that a c…
[60]Fullerene l -Amino Acids and Peptides: Synthesis under Phase-Transfer Catalysis Using a Phosphine–Borane Linker. Electrochemical Behavior
2017
International audience; A new method to link amino acid and peptide derivatives to [60]fullerene is described. It uses hydrophosphination with a secondary phosphine borane. First, the stereoselective synthesis of secondary phosphine borane amino acid derivatives was achieved by alkylation of phenylphosphine borane with gamma-iodo-alpha-amino ester reagents under phase transfer catalysis (PTC). Second, a sec-phosphine borane amino ester was saponified and coupled with alpha,gamma-diamino esters to afford the corresponding dipeptide derivatives in good yields. Finally, the hydrophosphination reaction of [60]fullerene by the sec-phosphine borane compounds was performed under PTC to obtain C-60…
Implantación de un Programa de Optimización de Antimicrobianos en una unidad de pacientes críticos
2018
Introducción: La optimización del tratamiento antimicrobiano es un elemento clave para mejorar la respuesta al tratamiento de los pacientes con infecciones graves, reducir el riesgo de eventos adversos asociados a los mismos y minimizar la generación y selección de cepas bacterianas multirresistentes. Durante la última década, los programas de optimización de antimicrobianos (PROA) han surgido como herramientas de gran utilidad para garantizar el uso racional de los mismos. No obstante, la experiencia descrita sobre su implantación en las unidades de pacientes críticos es reducida. Por otro lado, en un entorno de recursos limitados, se hace necesario evaluar el impacto de este tipo de progr…
Multi-objective parameter identification via ACOR algorithm
2009
The spreading of advanced constituive models, needed to model complex phenomena, makes necessary to solve difficult parameter identification problems. The need of multiple tests to fully characterize the experimental behaviour makes the parameter identification problem a multi objective one. Unlike conventional techniques, based on the formulation of an aggregate scalar ob- jective function, in the present work the problem is addressed using a new multi objective algorithm obtained extending the continuous Ant Colony Optimization algorithm. Mathematical tests and ap- plication to a real world problem are performed and different performance measures are used to asses the performance of the a…
Shape optimization in contact problems : Approximation and numerical realization
1987
The optímal shape design of a two-dimensíonal elastic body on rigid foundatíon is analyzed. The relation between the continuous problem and the díscrete problem achieved by FEM is presented. A numerícal realization together wíth the sensítivity analysís is given. Several numerical examples to illustrate the practícal use of the methods are presented. peerReviewed
Coping Strategies against peer victimization: differences according to gender, grade, victimization status and perceived classroom social climate
2021
The Sustainable Development Goals (SDGs) include “Good Health and Well-being” (SDG3) and “Quality Education” (SDG4). Nevertheless, many students cannot achieve these goals if they suffer peer victimization at their schools, and intervention programs to reduce it are necessary. These programs should consider the possible differences in the coping strategies preferred by students according to some personal (e.g., gender, grade, victimization status) and contextual (e.g., perceived classroom social climate) factors to be more effective. Therefore, the objective of this study was to analyze the possible differences in the coping strategies preferred by students (ask a friend for help, ask a tea…
Psychosocial Profile of Spanish Adolescent Aggressors and Victims of Dating Violence
2018
Resumen El objetivo de este estudio fue analizar posibles diferencias en satisfacción con la vida, ánimo depresivo, autoconcepto y comunicación familiar entre adolescentes no implicados en violencia de pareja, agresores, víctimas, implicados en el rol de agresor-víctima de forma ocasional e implicados en este rol frecuentemente. Participaron 672 adolescentes españoles (325 chicas, 347 chicos), entre 12 y 19 años (M = 14.45; DT = 1.62). Los resultados muestran un perfil psicosocial más negativo en las chicas víctimas de violencia de pareja y en los chicos implicados frecuentemente en el rol de agresor-víctima. En las chicas con mayor implicación en violencia de pareja se observan también may…
Finnish Health Care Professionals’ Views of Patients Who Experience Family Violence

Box 35, Jyvaskyla, 40014 Finland. Email: juha.m.holma{at}jyu.fi The aim of this study was to examine the beliefs health care personnel have about patients who experience family violence. This was done by analyzing the positions constructed for such patients using content analysis. The data comprise six focus groups conducted with physicians, nurses, social workers, and psychologists working in a maternity unit, a psychiatric ward, and an emergency department. The research team collected the data in…
