This study is based on questionnaires, letters, and short biographies written by 92 ordinary Swedish citizens. Most of them had visions of Jesus or of angels and "divine light". The questionnaires focus on changes concerning religious activity, attitude towards the Bible, concept of God and religious orientation. The author has chosen to describe 35 cases in the form of short biographies (4-6 page
Popular Abstract in Swedish Gel-dosmätningar för kontroll av strålbehandling av cancertumörer När en patient strålbehandlas avser man att bestråla sjuka områden i kroppen. Det är dock omöjligt att göra detta utan att därmed även till viss del stråla på omkringliggande organ och komplikationer kan då uppstå. För att minimera dessa bieffekter och optimera behandlingen används ofta en så kallad dospGel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. Single clinical electron and photon beams were evaluated and gel dose distributions were mainly w
The Swedish director Ludvig Josephson (1832-99) made a decisive contribution to the breakthrough of theatrical direction during the latter half of the 19th century in Sweden, and even to a certain extent in Norway. The aim of this dissertation is to examine Josephson's aesthetic program and to relate his contribution to continental developments. Theatrical direction here includes both dramatic the
The focus of this article has been to analyse the machinability, with focus on surface integrity, of oxygen-free copper (OFC) and niobium during turning operations. The results from machining OFC proved that all of the tools that was tested can be used to achieve a surface roughness below Ra = 0.8 µm with the correct cutting data. From the results when machining niobium it showed that only the cem
Let A be a subset of the real line. We study the fractal dimensions of the k-fold iterated sumsets kA, defined as kA = {a(1) ... + a(k) : a(i) is an element of A}. We show that for any nondecreasing sequence {alpha(k)}(k=1)(infinity) taking values in [0,1], there exists a compact set A such that kA has Hausdorff dimension ak for all k >= 1. We also show how to control various kinds of dimensions s

This note studies lumped-delay approximations of distributed-delay elements arising in various problems involving delay compensation or preview utilization. Several approaches to reduce implementation complexity, understood as the number of delays required to attain a required accuracy level, are put forward. First, we derive the H2-optimal coefficients for a given delay pattern. This can be seen
Popular Abstract in Swedish Vår arvsmassa (DNA) finns packad i cellkärnan i de flesta kroppsceller i form av 46 kromosomer (23 par). Könscellerna innehåller ett halverat antal kromosomer. Det korrekta kromosomtalet hos människa beskrevs i Lund 1956, av Tjio och Levan. Kromosomerna innehåller tillsammans 50000-100000 gener, vilka är de delar av DNA-strängen som kan avläsas till proteiner. Cancer ärIn the present thesis benign breast lesions of various histologies, i.e., fibrocystic lesions from women with and without a known hereditary predisposition to breast cancer, fibroadenomas, phyllodes tumors, and papillomas were cytogenetically investigated with the aim to characterize the chromosomal patterns, and to relate the findings with those in breast carcinomas. No lesion-specific aberration
