Risk and Vulnerability Analysis of Large Scale Technical Infrastructures - Electrical Distribution Systems

The thesis treats the subject of risk and vulnerability analysis of large-scale technical infrastructures. In particular the focus is on the development of methods for vulnerability analysis of electrical distribution systems. The methods and the concepts behind them should nevertheless also be seen as applicable to other technical infrastructures. Robust and reliable technical infrastructures are

Breastfeeding and its impact on daily life in women with type 1 diabetes during the first six months after childbirth: a prospective cohort study

For mothers with diabetes, breastfeeding is a great challenge due to their struggle with potentially unstable blood glucose levels. This paper explores breastfeeding attitudes and impact of breastfeeding on the daily life of mothers with type 1 diabetes compared with non-diabetic mothers.Methods: We performed a prospective cohort study of 108 mothers with type 1 diabetes and a reference group of 1

Pathogenic paths? A time geographical approach in medical geography

Medical geography usually attempts to disentangle and explain the ecological and causal contexts of health, disease and environment by mapping spatial patterns of cases and potential pathogenic factors. However, many diseases are believed to show after long periods of latency , spanning years and even decades between initial exposure and clinical onset. In view of high spatial human mobility - in

Skriftkultur, bokkultur, tryckkultur

Human script culture is not limited to texts of learning and entertainment. By the use of script and print technology to communicate and preserve, societies have grown. Graphic messages pervade cities as commercial and communal signs, and the long dependance on print in society is shown as well by all the ephemeral products of job printing as by the symbolic position of the book in religions. This

Optimizing flow cytometric DNA ploidy and S-phase fraction as independent prognostic markers for node-negative breast cancer specimens

Developing a reliable and quantitative assessment of the potential virulence of a malignancy has been a long-standing goal in clinical cytometry. DNA histogram analysis provides valuable information on the cycling activity of a tumor population through S-phase estimates; it also identifies nondiploid populations, a possible indicator of genetic instability and subsequent predisposition to metastas

Air and biological monitoring of solvent exposure during graffiti removal

OBJECTIVE: The principal aim of the study was to estimate the level of exposure to organic solvents of graffiti removers, and to identify the chemicals used in different cleaning agents. A secondary objective was to inform about the toxicity of various products and to optimise working procedures. METHODS: Exposure to organic solvents was determined by active air sampling and biological monitoring

Plasma levels of six carotenoids in nine European countries: report from the European Prospective Investigation into Cancer and Nutrition (EPIC)

Background: In addition to their possible direct biological effects, plasma carotenoids can be used as biochemical markers of fruit and vegetable consumption for identifying diet-disease associations in epidemiological studies. Few studies have compared levels of these carotenoids between countries in Europe. Objective: Our aim was to assess the variability of plasma carotenoid levels within the c

(De)coding Modality : The Case of Must, May, Måste and Kan

This study investigates the mechanisms of (de)coding modality, focusing on the interpretation of utterances containing the modals must, may, måste, and kan. The main research question posed in this study is what enables the interlocutors to interpret modal expressions so that communicative goals are achieved. To answer this general question, Coates's (1983) study on modal contexts is initially rep

Does pond quality limit frogs Rana arvalis and Rana temporaria in agricultural landscapes? A field experiment

1. When assessing the cause of population absence or decline, it is important to understand the relative effect of local, regional and global factors. In this study we evaluated the first of these factors for two frog populations. 2. Amphibians are often absent from intensively farmed areas. There could be several reasons for this, one of them being the quality of the aquatic habitat available fo

Impact of teenage oral contraceptive use in a population-based series of early-onset breast cancer cases who have undergone BRCA mutation testing

Oral contraceptive (OC) use in young women has been associated with an increased risk of breast cancer. This matched case-control study aims to elucidate the combined effects of OC use and genetic factors in a population-based series of BRCA1/2 mutation-tested early-onset breast cancers. A first invasive breast cancer was diagnosed in 259 women aged <= 40 years between 1990 and 1995 in the South S

Genomewide linkage analysis of stature in multiple populations reveals several regions with evidence of linkage to adult height

Genomewide linkage analysis has been extremely successful at identification of the genetic variation underlying single-gene disorders. However, linkage analysis has been less successful for common human diseases and other complex traits in which multiple genetic and environmental factors interact to influence disease risk. We hypothesized that a highly heritable complex trait, in which the contrib
