  1. 1. Digital support for people with cognitive impairment : An intervention to increase the occupational performance in everyday life

    Författare :Maria Andreassen; Helena Hemmingsson; Tiny Jaarsma; Henrik Danielsson; Inga-Lill Boman; Susanne Guidetti; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Active reminder; Assistive technology for cognition; Cognitive impairment; Digital support; Habits; Occupational Performance; Occupational therapy; Rehabilitation; Smartphone; Stroke; Timemanagement;

    Sammanfattning : Introduction: Senior people with cognitive impairment may experience an inability to manage everyday life due to difficulties related to time management, and planning and structuring everyday life. These difficulties can affect people negatively, for example not remembering to carry out future planned activities. LÄS MER

  3. 2. XPS studies of an organic anode and hole-conductor system : PEDOT-PSS

    Författare :Stina Karin Maria Jönsson; Magnus Boman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with photoelectron spectroscopy of conducting polymer systems. A particular system, poly(3,4-ethylenedioxythiophene)­ polystyrenesulfonic acid (PEDOT-PSS), has been the main focus of this work. It is an aqueous colloidal dispersion consisting of doped conjugated polymer PEDOT with counter ions provided by the PSS chains. LÄS MER

    Sammanfattning : Chronic Heart Failure (CHF) is known to have a substantial impact on activities of daily living (ADL) and symptoms such as breathlessness and fatigue are characteristic. Despite this, research in occupational therapy concerning people with CHF is rare. LÄS MER

  5. 4. On the Process Development of an ECF Light Bleaching Sequence for the Production of High Quality Softwood Kraft Pulp and Low AOX Formation

    Författare :Sara Starrsjö; Juha Fiskari; Mikael Lindström; Olena Sevastyanova; Maria Boman; Peter Sandström; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical Engineering; Natural Science; Chemical Pulping; Softwood; Kraft Pulp; Bleaching; ECF light bleaching; Chlorine Dioxide; AOX formation; Delignification; Bleachability;

    Sammanfattning : The aim of this work is to contribute to the process development of the ECF light bleaching sequence Q(OP)D(PO) by providing a better understanding of the bleaching of softwood kraft pulp. There are few published studies on this type of sequence, and more knowledge is needed on how to reduce environmental impact, improve cost-effectiveness and ensure a high pulp quality. LÄS MER

  7. 5. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass

    Författare :Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

    Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER
