Laser-induced fluorescence studies of normal and malignant tumour tissue of rat following intravenous injection of delta-amino levulinic acid

Background and Objective: Laser-induced fluorescence was studied in normal and tumour tissue of rat after intravenous injection of delta-amino levulinic acid (ALA). The aim of the study was to investigate the protoporphyrin IX accumulation in different tissue types in rat after systemically administered ALA. Study Design/Material and Methods: A malignant rat tumour and normal tissue from 13 differ

Ethnic differences in asthma treatment among Swedish adolescents: A multilevel analysis of individual heterogeneity.

Adolescents with immigrant or ethnic minority background suffering from asthma receive on average less appropriate anti-asthmatic medication (AAM) than the majority population. However, those findings are based on analyses of differences between group averages which prevents our understanding of individual heterogeneity around the averages. Taking into account individual socioeconomic factors and

På spaning efter idrottsdidaktik

Popular Abstract in Swedish För ämneslärarexamen krävs att studenterna ska kunna bidra till kunskapsutvecklingen inom ämnesdidaktik. För lärarprogram med inriktning mot undervisning i Idrott och hälsa medför det att begreppet idrottsdidaktik behöver tydliggöras. I denna avhandling behandlas idrottsdidaktik som begrepp och som redskap för reflektion över idrottsundervisning. Idrottsdidaktik härledsIn search of sport didactics The aim of this thesis is to examine sport didactics as a concept and tool for reflecting on PE education. An additional aim is to analyze course literature and teaching models. Special focus is given to mandatory course literature devoted to dance, orienteering, swimming and ball games. The thesis starts by considering the concept of didactics. Further, different tra

On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine

In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels. In the first study, an initial investigation concerning the in- cylinde
