1. 1. Sedation with volatile anesthetics in cardiothoracic intensive care unit patients

   Författare :Jan Hellström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :sevoflurane;

   Sammanfattning : Volatile anaesthetics have been reported to provide protection against myocardial ischemia and reperfusion injury. This effect has been demonstrated in experimental studies when the volatile anaesthetics were provided either before (preconditioning) or after the ischemic period (postconditioning). LÄS MER

3. 2. Look-ahead Control of Heavy Vehicles

   Författare :Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

   Sammanfattning : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. LÄS MER

4. 3. On self-efficacy and balance after stroke

   Författare :Karin Hellström; Jan Lexell; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Cerebrovascular disorders; rehabilitation; physiotherapy; balance; self-efficacy; treadmill walking; activities of daily living; Neurovetenskap; Neurology; Neurologi; Rehabilitation Medicine; rehabiliteringsmedicin;

   Sammanfattning : The general aim of this work was to evaluate the outcome of specialised stroke rehabilitation and to examine the relation between both subjectively perceived and objectively assessed balance and impairments and some activity limitations. A further, integrated aim was to establish some psychometric properties and the usability of a newly developed Falls-Efficacy Scale, Swedish version (FES(S)) in stroke rehabilitation. LÄS MER

5. 4. Nutrient management in sewerage systems : investigations of components and exergy analysis

   Författare :Daniel Hellström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : The aim of this thesis is to present results from different experiments dealing with components that may be useful to improve nutrient management within sewerage systems. Further, exergy analysis is used to compare the utilisation of physical resources within different alternatives for sewerage nutrient management. LÄS MER

7. 5. Ab initio modelling of xanthates adsorbed on Ge and ZnS surfaces

   Författare :Pär Hellström; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

   Sammanfattning : The motivation for this modelling work, in close collaboration with experimentalists, is to contribute to the understanding of xanthate adsorption on ZnS surfaces in the flotation process. Adsorption of xanthates on Ge surfaces is investigated, which also have been studied experimentally in the Agricola Research Centre. LÄS MER
