The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibration

The present study shows the probable intrauterine infection with Chlamydia trachomatis in a premature infant born in the 29th week of gestation. Chlamydiae were isolated from lung tissue collected at sterile autopsy and also demonstrated in sections of such tissue by immunofluorescence tests using monoclonal antibodies.

Androgens, including 5 alpha-dihydrotestosterone (DHT), are known to play a role for spermatogenesis and accessory sex gland function. The enzyme 5 alpha-reductase (SRD5A) catalyses the conversion of testosterone to DHT. Our objective was to investigate whether polymorphisms in the SRD5A2 gene influence semen parameters in the general population. DNA from 182 Swedish military conscripts was examin

Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. In Finland, the sperm concentration was found to be substantially higher than in Denmark. In parallel, the incidence of testicular cance

This chapter describes the successful development of a new methodology for studying on-line writing. The text-logging tool ScriptLog has been combined with the eyetracking technology iView X HED HT, in order to enhance the study of the interplay between writing, monitoring and revision. Data on the distribution of visual attention during writing help determining to what extent pauses are used for

Hereditary defects of the von Willebrand factor (VWF) gene cause von Willebrand's disease (VWD) which shows great variability dependent on the nature and location of the mutation. We here describe the characteristics of a substitution of methionine for threonine 1156 in the D3 domain of the VWF, i.e. the domain involved in the intracellular multimerization of pro-VWF dimers. A VWD patient withseve

BACKGROUND: Non-bridging external fixation has been introduced to achieve better fracture fixation and functional outcomes in distal radius fractures, but has not been specifically evaluated in a randomized study in the elderly. The purpose of this trial was to compare wrist-bridging and non-bridging external fixation for displaced distal radius fractures. METHOD: The inclusion criteria were women

Anaesthesia with closed anaesthetic systems demands knowledge of the physiology of the patients and of how the various anaesthetic gases behave in the organism as only the gases which the patients produces and absorbs are eliminated and replaced. The system is educational as it provides knowledge of the genuine absorption of oxygen and anaesthetic gases. The method is favourable to the environment

Restless legs syndrome (RLS) is characterized by intense restlessness and unpleasant creeping sensations deep inside the lower legs. The symptoms appear when the limbs are at rest and are worst in the evening and at night. They force the patients to keep moving their legs, and sometimes to get out of bed and wander about. Periodic limb movements of the extremities (PLM) are common during sleep thu

Abstract This thesis consists of the following three papers Paper I. Hankel operators on Bergman spaces and similarity to contractions. In this paper we consider Foguel-Hankel operators on vector-valued Bergman spaces. Such operators defined on Hardy spaces play a central role in the famous example by Pisier of a polynomially bounded operator which is not similar to a contraction. On Bergman sp

Instrumentation, control and automation (ICA) are key technologies in modern water and wastewater systems. Despite the. variability of the influents the system outputs have to be satisfactory. Economic realities and new water directives encourage the application of ICA to make a maximum use of plant and other storage capacities. The final goal of protecting the environmental resources necessitates

New magnetic moments presented here allow stringent tests of the truncated shell model calculations performed in the region below the N = 50 neutron shell. The experimental g-factors for selected medium-spin yrast states in Mo-90 were determined via the IMPAD technique using the (Ni(Cl,3p))-Ni-58-Cl-35 reaction. The results of g(5-, 2549 keV) = +1.10 +/- 0.28, g(11-, 4842 keV) = +0.42 +/- 0.13 and

We study the folding thermodynamics of a beta-hairpin and two three-stranded beta-sheet peptides using a simplified sequence-based all-atom model, in which folding is driven mainly by backbone hydrogen bonding and effective hydrophobic attraction. The native populations obtained for these three sequences are in good. agreement with experimental data. We also show that the apparent native populatio

A core-excited sulfur state with a lifetime almost one order of magnitude longer than in molecular 2p core-hole states is selectively produced by ultrafast dissociation of S 2p -> sigma* excited OCS. Clear evidence for this is provided by strong atomic peaks (20% of the total intensity) in x-ray fluorescence but very weak ones (2%) in the corresponding resonant Auger spectrum. Corroborating the as

Proliferation, differentiation, and survival of hematopoietic cells are regulated by cytokines, acting through specific receptors. FLT3 ligand (FL) is one of the most important cytokines for regulation of the hematopoietic system, and its receptor FLT3 is expressed on both stem cells and progenitors. Regulation of Forkhead transcription factors has been described as an important mechanism to contr
