    Nyckelord :radiofrequency measurement; moisture content measurement; fuel characterization; biofuel; time domain measurement; Bulk measurement; Multivariate data analysis;

    Sammanfattning : 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%. LÄS MER

  4. 3. The Role of Kidney Oxygen Homeostasis for the Development of Kidney Disease

    Sammanfattning : The relation between oxygen supply and demand determines tissue oxygen tension (PO2). When intrarenal tissue PO2 decreases, any compensatory increase in oxygen supply via increased renal blood flow is likely to increase glomerular filtration rate. LÄS MER

    Sammanfattning : The overall aim of this thesis is to investigate why history textbooks are used the way they are and to identify possible reasons for the contradictions and dilemmas regarding the role of the textbook in history education. This thesis describes a case study of the history teaching at an upper secondary school class and investigates the attitudes of the pupils, teachers and textbook authors towards history, the teaching of history, textbooks and the use of textbooks.

  7. 5. Oxygen Metabolism in Experimental Kidney Disease

    Författare :Ebba Sivertsson; Fredrik Palm; Peter Hansell; Jenny Nyström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; kidney oxygenation; mitochondria; proteinuria; uncoupling protein; adenosine nucleotide transporter; diabetes; hyperthyroidism; thyroid hormone; hypertension; angiotensin II; CDK; AST-120; rats; mice; Fysiologi; Physiology;

    Sammanfattning : Tubulointerstitial hypoxia has been proposed a unifying mechanism behind the development of chronic kidney disease (CKD), regardless of primary diagnosis. Important factors that contribute to the development of hypoxia are reduced bioavailability of nitric oxide (NO), oxidative stress and mitochondria uncoupling. LÄS MER
