2. 1. Aspects of Ash Transformations in Pressurised Entrained-Flow Gasification of Woody Biomass : Pilot-scale studies

   Author : Charlie Ma; Marcus Öhman; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; woody biomass; gasification; ash transformation; slag behaviour; refractory corrosion; Energiteknik; Energy Engineering;

   Abstract : Pressurised entrained-flow gasification (PEFG) of woody biomass has the potential to produce high purity syngas for the production of vital chemicals, e.g., biofuels. However, ash-related issues such as reactor blockages and refractory corrosion need to be addressed before this potential can be realised from a technical perspective. READ MORE

4. 2. From torrefaction to gasification : Pilot scale studies for upgrading of biomass

   Author : Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

   Abstract : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

5. 3. Analysing synergies between urbanization and sustainable development : Developing a draft theory through historical pilot studies

   Author : Carina Weingaertner; Örijan Svane; Marie Thynell; KTH; []
   Keywords : urbanization; sustainable development; historical pilot studies; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Abstract : Urbanization is an ongoing process all over the globe. People moving from rural to urban areas are the primary cause of urbanization, and history indicates that this movement of people is very hard to influence. READ MORE

6. 4. Healthcare consumption, experiences of care and test of and intervention in frail old people. Implications for case management

   Author : Jimmie Kristensson; Institutionen för hälsovetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long Term Care; Primary Health Care; Outpatients; Registries; Pilot Studies; Content Analysis; Case Management; Hospital; Emergency Services; Frail Elderly; Hospitalizations; Intervention Studies; Health Care Costs;

   Abstract : The overall aim of thesis was to explore frail older people’s experiences of receiving healthcare and/or social services and to investigate healthcare consumption and costs in both men and women and in different age groups in the two years prior to the introduction of long-term municipal care. A second aim was to explore a preventive intervention in a pilot study using case managers to older people with functional dependency and repeated healthcare contacts. READ MORE

7. 5. Parkinson’s Disease and Communication : Intelligibility, Interaction and Participation

   Author : Inga-Lena Johansson; Nicole Müller; Christina Samuelsson; Christina Reuterskiöld; Margaret Walshe; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parkinson’s disease; Intelligibility; Speech acoustics; Interaction; Communicative participation; Communication partner;

   Abstract : Parkinson’s disease is a neurodegenerative disorder affecting dopamine production in the basal ganglia. It is a common cause of disability among elderly people. The main symptoms are tremor, rigidity, and bradykinesia, but there is a substantial individual variation of how the disease manifests itself. READ MORE
