The work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion

Labour is said to be obstructed when the presenting part fails to descend through the birth canal despite strong uterine contractions. The condition is mostly prevalent in low-income countries where the main causes are cephalopelvic disproportion and malpresentation. The overall aim of this thesis was to investigate the individual, community and health system factors associated with obstructed lab

Lung cancer accounts for 1.6 million cancers annually and 1.3 million deaths per year make the disease the deadliest type of cancer. Smoking is the most prominent cause. High mortality rates are partly due to late diagnosis which limits the therapy options. Improved understanding of molecular and biological mechanisms of tumor development could guide current therapy selection or pave way for novel

Life cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building. The goal of this project was to calculate the environmental releases for a whole office building and investigate the contribution in terms of environmental impact for different parts of the building, as well as the impact from different stages of the life c

Background: The ageing population is increasing worldwide, and this trend is bringing challenges both for the older person and for society. In order to meet the challenges a comprehensive approach is needed involving both health promotion and risk prevention. The preventive home visit is a public health intervention used around the world with the purpose of promoting health and preventing risk amo

The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors. In one part of the

Background: Indoor lighting, exposure to outdoor daylight, physical activity and sleep interact to influence functioning, mood and cicadian rhythm. Older adults (≥ 65 years), who often spend more time at home, are less physically active and experience more sleep problems, could benefit from strategies to support behavioural change and self-managed modifications in the home. The study’s primary objBackgroundIndoor lighting, exposure to outdoor daylight, physical activity and sleep interact to influence functioning, mood and cicadian rhythm.
