Many periodic solutions for a second order cubic periodic differential equation / Buică, Adriana (Universitatea Babeş-Bolyai. Departamentul de Matematică (Romania)) ; Gasull i Embid, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
The aim of this work is to provide results that assure the existence of many isolated T-periodic solutions for T-periodic second-order differential equations of the form x'' = a(t)x+b(t)x2+c(t)x3. We use bifurcation methods, including Malkin functions and results of Fonda, Sabatini and Zanolin. [...]

9 p, 409.1 KB Heroin-dependent patient satisfaction with methadone as a medication influences satisfaction with basic interventions delivered by staff to implement methadone maintenance treatment / Alcaraz, Saul (Institut d'Investigació Biomèdica Sant Pau) ; Viladrich, Carme (Universitat Autònoma de Barcelona. Departament de Psicobiologia i de Metodologia de Ciències de la Salut) ; Trujols, Joan (Institut d'Investigació Biomèdica Sant Pau) ; Siñol, Núria (Institut d'Investigació Biomèdica Sant Pau) ; Pérez de los Cobos, José (Institut d'Investigació Biomèdica Sant Pau)
The aim of the present study was to test a structural equation model of patient satisfaction with different key facets of methadone maintenance treatment (MMT). In this model, the three dimensions of patient satisfaction with methadone as a medication (ie, personal functioning and well-being, anti-addictive effect on heroin, and anti-addictive effect on non-opioid substances) were expected to predict satisfaction with the basic interventions delivered by the staff of treatment centers to implement MMT.
