  1. 1. Semiconductor Hetero- and Nanostructures

    Författare :Jonas Ohlsson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heterostructures; Nanowhiskers; Semiconductory physics; Chemical Beam Epitaxy; Nanostructures; Halvledarfysik; Fysicumarkivet A:2001:Ohlsson;

    Sammanfattning : In this thesis, chemical beam epitaxy was used to fabricate nm-sized crystalline structures. Most of the systems were based on heterostructures, i.e., combinations of different kinds of crystalline materials. LÄS MER

  2. 2. Salix as a biorefinery feedstock : an inquiry into factors affecting conversion performance

    Författare :Jonas Ohlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Lignocellulosic biomass is one of the world’s greatest natural resources, with po-tential for replacing a considerable portion of current fossil resource use. Although lignocellulosic biomass can be readily utilized for generating heat and power via combustion, its conversion into storable fuels such as ethanol and biogas presents a greater challenge.

    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood lactate concentration; cross-country sit-skiing; impairment; internal kinetics; inverse dynamics simulations; joint reaction forces; kinematics; metabolic rate; musculoskeletal modelling; musculoskeletal efficiency; nordic skiing; oxygen uptake; para-skiing; respiration; skiing efficiency.;

    Sammanfattning : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. LÄS MER

  5. 5. Shaping electronic news : A case study of genre perspectives on interaction design

    Författare :Jonas Lundberg; Kjell Ohlsson; Sture Hägglund; Vivian Vimarlund; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Electronic publishing; online newspaper; hypervideo news; hypermedia news; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : This thesis describes and analyzes implications of going from hypertext news to hypermedia news through a process of design, involving users and producers. As in any product development, it is difficult to conceive design of a novel news format that does not relate to earlier genres, and thus to antecedent designs. LÄS MER
