The objective of this study is the experimental and numerical investigation of flame spread over a PMMA surface. A series of upward flame spread tests were carried out in a cylindrical combustion room, with measurements made for gas velocity, surface temperature and surface heat fluxes. A CFD based flame spread model was then used for the simulation of the experiment. This model consists of a four

This thesis comprises five papers discussing two case studies – the mega-event World Championships in Athletics 1995 in Göteborg and the regional festival Storsjöyran in Östersund, Sweden. The study adopts an organisational-theoretical perspective and focus on both intra- and interorganisational aspects of the marketing work. The purpose is to understand the structure and the processes of the orga

In the article the spatial organisation of everyday life at two deserted medieval farmsteads/hamlets, and the practise of outland use in their surrounding landscapes are discussed from a gender perspective. A gender hierarchy, with male domination, is clearly visible in the matierals.

Popular Abstract in Swedish Bakgrund Många känner idag till att det är viktigt att gamla läkemedel lämnas in till apoteken för att de inte ska hamna i naturen. Det som man oftast inte känner till är att även de läkemedel som vi konsumerar riskerar att tillslut hamna i naturen. Eftersom svenska reningsverk bara tar bort en bråkdel av läkemedelsresterna i vår urin. Det här leder till att man vid utlPharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e., 17α-Ethinylestradiol (EE2) and diclofenac). The main aim of this thesis

Popular Abstract in Undetermined The transparent wings of tiny parasitic wasps and small flies are remarkably thin, only a few hundreds nanometers thick, and may appear to have a simple structural airfoil design. The thesis deals with new findings about structural color reflections and the ultrastructure of such tiny transparent wings of parasitic wasps. The main discovery is that when seemingly tThe remarkably thin transparent wing membranes in tiny wasps may appear to have a simple structural design, but hide a largely unexplored complex of micro-morphological features that serve aerodynamics and may also function in visual signaling. I found that when such small transparent wings are viewed against a dark background they display vivid structural color patterns due to thin film interfere

Many courses within higher education are assessed by “faculty standards” sometimes based on the implicit assumption that “it has always been like this, therefore it is the best”. Selecting and combining different assessment modes in an effective manner for a particular course are central issues. The process does not always entail a simple and straight-forward decision making. The main purpose of t
