  1. 1. Estimating source area of pollen and pollen productivity in the cultural landscapes of southern Sweden - developing a palynological tool for quantifying past plant cover

    Author : Anna Broström; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerial photographs; pollen productivity estimates; relevant source area of pollen; southern Sweden; quantitative landscape reconstruction; GIS; pollen dispersal; simulation model; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. READ MORE

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

    Author : Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Cognitive function in elderly patients with chronic heart failure

    Abstract : IntroductionApproximately 1-2% of the adult population in developed countries suffer from heart failure (HF), with the prevalence rising to more than 10% among patients 80 years of age or older. The HF syndrome is associated with elevated mortality and morbidity, and decreased quality of life. READ MORE

  4. 4. Enhanced external counterpulsation treatment in patients with refractory angina pectoris with emphasis on physical capacity, health-related quality of life and safety : An explorative and interventional study

    Author : Eline Wu; Jan Mårtensson; Anders Broström; Liyew Desta; Anna Ehrenberg; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse event; enhanced external counterpulsation; experiences; health-related quality of life; physical capacity; refractory angina pectoris; safety;

    Abstract : Background: Patients with refractory angina pectoris (RAP) suffer from debilitating symptoms with considerable limitation of functional capacity and impaired health-related quality of life (HRQoL) despite optimised medical therapy. In addition, frequent angina symptoms are strongly associated with psychological distress. READ MORE
