  2. 1. Rapid measurements of the moisture content in biofuel

    Author : Jenny Nyström; Erik Dahlquist; Stefan Backa; Eva Thorin; Bo Franzon; Clarke Topp; Mälardalens högskola; []
    Keywords : radiofrequency measurement; moisture content measurement; fuel characterization; biofuel; time domain measurement; Bulk measurement; Multivariate data analysis;

    Abstract : An increasing number of power plants in Scandinavia are beginning to use biofuel instead of coal or oil. The material in the new fuel is a mixture of woodchips, mostly Pine, Spruce and Salix, bark, GROT (tops and branches from felling waste) and sawdust from sawmills. It is heterogeneous, having a moisture content varying from 15% up to 65%. READ MORE

  4. 2. On the subjective–objective distinction for measures of memory and cognition : Theoretical and methodological issues in questionnaire development and validation

    Author : Peter Vestergren; Widar Henriksson; Christina Wikström; Michael Rönnlund; Björn Lyxell; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive dysfunction; measurement; memory complaints; self report; subjective memory; subjective–objective; Other social sciences; Övrig samhällsvetenskap; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : The aim of this thesis was to develop a questionnaire for cognitive functioning, which could possibly be used as a screening instrument for early signs of dementia in the future. The introduction discusses the often made distinction between subjective and objective measures. READ MORE

  5. 3. Zinc Oxide Bulk and Nanorods

    Author : Peter Klason; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc oxide; Schottky contact; buckling; annealing; semiconductor growth; ion implantation; photoluminescence; nanorods;

    Abstract : Zinc Oxide (ZnO) has many promising properties for optoelectronics, sensor applications, transparent electronics etc. To mention a few, ZnO has a large exciton binding energy (60 meV at room temperature) and a direct wide bandgap energy of 3.37 eV. In addition, ZnO is piezoelectric and shows more resistance to radiation damage than Si and GaN. READ MORE

    Author : Jinxia Li; Henrik Åström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Lubricating grease is commonly applied to lubricate e.g. rolling bearings, seals and gears. Grease has some clear advantages over lubricating oil. READ MORE

  7. 5. Investigation of deep levels in bulk GaN

    Author : Tran Thien Duc; Erik Janzén; Franziska C. Beyer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The first gallium nitride (GaN) crystal was grown by hydride vapor phase epitaxy in 1969 by Maruska and Tietjen and since then, there has been an intensive development of the field, especially after the ground breaking discoveries concerning growth and p-type doping of GaN done by the 2014 year Nobel Laureates in Physics, Isamu Akasaki, Hiroshi Amano and Shuji Nakamura. GaN and its alloys with In and Al belong to a semiconductor group which is referred as the III-nitrides. READ MORE
