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
This doctoral dissertation was driven by an inspiration to study how employees behave toward each other from an interactive perspective where all members of an organization are considered active contributors. Employeeship holds this perspective and acknowledges the importance of productive relationships. The objective of this dissertation is to contribute to the conceptual and methodological devel
One way to increase distribution network reliability is to replace traditional overhead lines with underground cables. To fully utilize these investments, network owners will have to adjust their reliability engineering methods to suit the new cable networks. In this paper different condition assessment methods as well as improved failure statistics for cable systems are considered. The paper is b
Atlantic salmon (Salmo salar) from the Baltic Sea suffer from a reproduction disease known as the M74-syndrome. Newly hatched fry develop nerve disorders and die between 3-5 days after the first symptoms are seen. This is a maternally transmitted disease that is casued by a thiamine (vitamin B1) deficiency. The factor(s) that casue(s) this thiamine deficiency are largely unknown. However, several
Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. Costs for transportation are high and are predicted to increase, new environmental demands are being imposed on transportation and rationalizations are centralizing public and commercial services. These facts make
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
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
BACKGROUND: Information on cancer prevalence is of major importance for health planning and resource allocation. However, systematic information on cancer prevalence is largely unavailable. MATERIALS AND METHODS: Thirty-eight population-based cancer registries from 17 European countries, participating in EUROPREVAL, provided data on almost 3 million cancer patients diagnosed from 1970 to 1992. Sta
This article discusses the actress and singer Zarah Leander (1907-1981), one of the most celebrated female stars in German Nazi Cinema 1936-43. She is a contradictory figure, and her star persona has always been a negotiation of antagonistic formulations, thus pointing to modes of audience identification and specatorship issues, most strikingly articulated through her immense popularity in the pos
BackgroundWarfarin is demonstrated to be superior in efficacy over antiplatelet agents for the prevention of stroke, but the relationship between warfarin and mortality is less clear. Our aim was to investigate this relationship in a large cohort of unselected patients with atrial fibrillation and ischaemic stroke. MethodsThis observational study was based on patients who were discharged alive and
BACKGROUND: Progressive immune dysfunction and the acquired immunodeficiency syndrome (AIDS) develop in most persons with untreated infection with human immunodeficiency virus type 1 (HIV-1) but in only approximately 20 to 30% of persons infected with HIV type 2 (HIV-2); among persons infected with both types, the natural history of disease progression is poorly understood. METHODS: We analyzed d
Counter-regulatory responses are critical to prevent hypoglycemia in subjects with type 2 diabetes. This is particularly important in insulin-treated patients. This study explored the effect of the glucagon-like peptide 1 receptor agonist lixisenatide on the hormonal counter-regulatory responses to insulin-induced hypoglycemia when added to basal insulin therapy in subjects with type 2 diabetes.
There is limited information about whether time from recognition of decreased perfusion to revascularization affects the probability of healing in a patient with a diabetic foot ulcer. The aim of the present study was to examine whether time to revascularization after referral to a multidisciplinary foot center was related to the outcome of foot ulcers in patients with diabetes and severe peripher
Children with type 1 diabetes have been identified as a risk group for non-alcoholic fatty liver disease (NAFLD). The aim was to compare total hepatic fat fraction and fat distribution across Couinaud segments in children with type 1 diabetes and controls and the relation of hepatic fat to plasma and anthropometric parameters.
