In this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy. The band alignment of GaAs pseudomorphically grow
Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity. Early recognition of vascular changes, both structural and functional, may help to identify individuals at risk for CVD. Using modern ultrasound techniques – the echo-tracking technique for assessment of stiffness in large arteries and flow-mediated dilatation of the brachial artery as an indicator of endothelial
Antibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer. Despite tremendous advances in all fields
Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. To limit the growth of this fouling layer a flow is applied tangentially to the membrane
Glass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo
The work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking acce
This thesis consists of four independent exploratory research papers contributing to the economic literature on child and adolescent health, and adult educational and labor market outcomes. Each paper considers type 1 diabetes and focuses on onset over a specific age span. An overall conclusion of this thesis is that individuals with type 1 diabetes deviate from peers without diabetes, irrespectiv
Members of the protein kinase C (PKC) family of serine/threonine kinases play critical roles in cellular regulation. Depending on differences in regulation, PKCs can be divided into classical (alpha, betaI, betaII and gamma), novel (delta, epsilon, eta and theta) and atypical (zeta and iota/lambda) isoforms. When PKCalpha is inactive it is maintained in a closed conformation by intramolecular inte
When first-century gentile Christians withdrew from the traditional and civic Graeco-Roman cults and increasingly began to be identified by the Romans as not belonging to mainstream or common Judaism, they soon found themselves pressed "between synagogue and state." On the one side, the fact that they did not observe the Torah elicited hostility from Jews who did not want to be identified with a m
There are various ways in which Enterprise Architecture (EA) is defined these days. One of the more common definitions is that EA is a dashboard that allows business architects and other stakeholders to govern an enterprise’s transformation process. This dashboard shows current operations as well as its future and desired state. In theory this might seem as a good tool for enterprise architects bu

In order to help the rescue service to do an efficient and secure operation in complex buildings, operation plans are used. To investigate the need of an operation plan adapted for natural environment and collect information to be used at the establishment of one, a literature review and a semi-structured interview study was conducted. The interview study consisted of interviews with national park
