  2. 1. Personality, Health and Mortality of Workers in a PVC Production Plant in Sweden A longitudinal study

    Author : Margareta Ardeberg; Miljö- och energisystem; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; disease; recovery; personality alterations; solvents exposure; PVC; polyvinyl chloride; Sjöbring personality psychology; behavioural toxicology; MNT scale; MFS scale; Eysenck; Psychology; Psykologi;

    Abstract : A longitudinal study was initiated in a PVC production plant in 1967. It was repeated in 1987. A cohort of 101 workers was followed. The aim of the 1967 study was, after a heavy rise in absenteeism and sick leave, to analyze perceptions of work environment and health. READ MORE

  4. 2. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors

    Author : Mostafa Jabbari; Mikael Hedenqvist; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; textile bioreactor; biofuel; coated fabric; all-polyamide composite; polyvinyl chloride PVC ; solvent replacement; Hansen solubility parameters HSPs ; Resource Recovery; Resursåtervinning;

    Abstract : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. READ MORE

    Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.

  7. 5. Morphology of Polymers - Development of Electron Microscopy Methods

    Author : Helen Hassander; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; polymer; electron microscopy; Polymer technology; biopolymers; Polymerteknik;

    Abstract : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. READ MORE
