A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. A scintillation camera allowing single photon emissi
Water column and sediment profiles of plutonium, americium, thorium and uranium have been obtained in the superanoxic Framvaren fjord, southern Norway. The concentrations of bomb test fallout Pu, Am as well as 'dissolved' Th in the bottom water are the highest recorded in the marine environment. The behaviour of the actinides in the anoxic water mass is to a large extent governed by the behaviour
The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. Using the Charge Exchange diagnostic system at JET, ion temperatures, rotation velocities and densities have been derived from visible spectroscopic measurements on fully ionised light
A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. The tool, "FREIA", evaluates the consequences for humans and components due to fires and accidental releases indoors and outdoors using established engineering m
This book is about elections and democracy in newly democratizing countries. Building on a new data set of 5,568 observations in 232 elections, it provides evidence elections have a casual impact on improving the quality of democracy in Africa in more than one way. The study demonstrates multiparty elections do not signal the end of transitions to democracy but rather foster liberalization and hav
The work examines developments in the novel and the short story of writers who grew up during the New Order era (1966-1998) in the period of reform post 1998. It is assumed and subsequently affirmed that the genres are developing, modern genres in dialogue with the past and present. The work's main use of theory is that of M. M. Bakhtin's ideas of dialogism. The assumption of 'novelization' is fra
Uppsatsens mål är att utifrån ett feministiskt och postkolonialt perspektiv belysa den diskursiva konceptualisering av integration som artikuleras i jämlikhetskommissionens betänkande. Vidare är målet att undersöka vilka idéer om det svenska medborgarskapet som betänkandets konceptualisering av integration bygger på och ger upphov till. Genom att belysa och undersöka detta ämnar uppsatsen begripli
Under 2017 återaktiverades totalförsvarsplikten för alla svenska medborgare. Situationen startade igång diskussioner kring jämställdhetsintegrering eftersom Sverige porträtterar sig själva som en modern, jämställd, nation. Utöver detta är Sverige en medlemsstat av Förenta Nationerna (FN) och måste förhålla sig till FN:s säkerhetsrådsresolutioner. Därmed behöver staten nationellt implementera Resol
The human race has for a long time contributed to an increase of the environmental problems, however in recent times they have begun to deploy measures to counter this. One of these measures is environmental classification systems, which is used in the construction- and property sector. Environmental classification systems are methods which evaluate a building's environmental performance in or
The principles of sanctity of life and quality of life are often appealed to in medical decisions at the "edges of life." Notwithstanding their importance in bioethics, these principles are still badly understood. This study is an attempt to clarify their normative significance and content. Because these principles pertain to the more general question of the value of life, the study begins by exp
A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. Formulas for in-rack flame height, excess gas temperature, gas velocity and heat flux to storage walls are provided. The formulas include overall heat release rate,
Friction-related problems are frequently encountered in control systems. This thesis treats three aspects of such problems: modeling, analysis, and friction compensation. A new dynamic friction model is presented and investigated. The model is described by a first order nonlinear differential equation with a reasonable number of parameters, yet it captures most of the experimentally observed frict
The aim of this dissertation is to study some of the forces behind the transformation of the 20th century industrialised countryside. The emphasis is on changes in everyday life for women and men, and the role of organisations therein. Two main questions are outlined: Which forces were central to the development of the industrial society?, and, how did the relationship between individual and socie
