Abstract

This contribution focuses on understanding of paper wet-strength properties, by taking a closer look at the spatial distribution of wet-strengthening polymers inside the cellulosic fiber network deposited under different treatment conditions using confocal laser scanning microscopy as in situ imaging tool. We compare the behavior of paper samples treated with a photochemically cross-linkable copolymer using an impregnation process employing three different solvents, namely water, 2-propanol (IPA) and 1-butanol (BuOH), respectively. As these solvents swell paper fibers to quite different extents, the deposition of the polymer, on, in or in-between the cellulosic fibers varies quite strongly, as is shown by in-depth analysis using confocal laser scanning microscopy. The difference in accessibility of distinct surface sites exclusively on or also in and between the fibers controls the macroscopic tensile strength under both dry and wet conditions.

Abstract

Systemtheoretische Untersuchung über den Grad der Interdependenz oder Interpenetration des Sport- und Mediensystems in Deutschland, Italien und der Schweiz basierend auf zahlreichen Tiefeninterviews in den drei Untersuchungsländern. Die Dissertation enthält einen systematisch gegliederten Katalog der gegenseitigen Einflussmöglichkeiten der Systeme Sport und Medien. Die Untersuchung gliedert den Sport in Breiten-, Leistungs- und Mediensport und fügt die neue Bezeichnung Profitsport für den Sport im Sportmedienkomplex hinzu. Die Arbeit plädiert für eine strengere Unterteilung der Begriffe innerhalb des Sports und der Überführung des Profitsports aus dem Sportsystem in das Wirtschaftssystem., Analysis about the level of interdepency and interpenetration between the sport and the media system in Germany, Italy and Switzerland. The survey is based on numerous depth interviews within the three countries. The dissertation contains a catalogue of the various possibilities of mutual influences between sport and media and structures the system sport in popular sport, professional sport, media sport and (as a new denomination) profit sport.

Abstract

Victoria C Ritter,1 Tore Bonsaksen1,21Faculty of Health Sciences, Department of Occupational Therapy, Prosthetics and Orthotics, OsloMet – Oslo Metropolitan University, Oslo, Norway; 2Faculty of Health Studies, VID Specialized University, Sandnes, NorwayBackground: Parkinson’s disease follows a chronic course, and therefore quality of life is important to assess in relation to rehabilitation programs for persons with the disease.Aim: To examine whether a brief rehabilitation program can promote positive changes in functional status, general self-efficacy, and quality of life and to examine factors associated with changes in quality of life.Methods: Patients with Parkinson’s disease (n=83) completed the General Self-Efficacy Scale and the Parkinson’s Disease Questionnaire at the beginning of a rehabilitation program and at three weeks follow-up. Within-person changes were analyzed with paired t-tests. A hierarchical linear regression was conducted to assess the independent associations between the independent variables and changes in quality of life during the three weeks program, while adjusting for the covariance between the independent variables.Results: Patients reported higher functional status (d=0.37, p
