It is shown how first-order performance estimation of high-orderadaptive optics (AO) systems may be efficiently implemented in a hybridnumerical simulation by the use of 1) sparse matrix techniques forwavefront reconstruction, 2) undersampled pupil-plane turbulence-inducedaberrations, and 3) analytical models that compensate - in the limit ofinfinite exposure time - for the errors introduced by un
Degradation of the dry semiarid ecosystems in the Mu Us Sandy Land of north central China was explored using high-resolution satellite images from 1978, 1987 and 1996. This study monitored both changes in grassland biomass production and reclamation activities to detect the nature and scale of land degradation since major economic reforms were introduced in 1978. The position of the high-resolutio
A two-phase hollow-fiber (HF) liquid-phase microextraction (LPME) method was developed for determination of a quaternary ammonium compound surfactant, dicocodimethylammonium chloride, in aqueous samples. The porous HF was fixed on a metal rod support and was impregnated with approximately 6.6 mu L of organic extractant, which was immobilized in the HF pores. Surfactant extraction was facilitated b
Aim:The aim was to analyse any associations between socio-demographic and psychosocial factors and different features of the metabolic syndrome in a geographically well-defined population of middle-aged women. Methods:A population of 10 766 Caucasian women aged 50-59 years was investigated regarding biological and socio-demographic conditions, physical activity, dietary habits, aspects of quality
This thesis is focused on the early steps of a complex virus-cell interaction. The human adenovirus type 2 (HAdV-2) infects permissive cells, by first recognizing a protein of the immunoglobulin superfamily that serves as the Coxsackie and adenovirus receptor (CAR). This attachment step is mediated by the adenovirus fiber protein. Subsequently, in order to proceed to a tighter binding, the viral p
During Subzero project there were observed some differences between different manikins. In order to study the differences closer complementary measurements were carried out on 2 manikins representing male and female body shapes. Comparison was carried out based on: • tight versus loose clothing; • serial versus parallel calculation model; • even versus uneven clothing (insulation) distribution; •
Since a tightly regulated complement system is needed for a successful pregnancy, we hypothesized that alterations in complement inhibitors may be associated with idiopathic, recurrent miscarriage. We sequenced all exons coding for three complement inhibitors: C4b-binding protein (C4BP), CD46 and CD55 in 384 childless women with at least two miscarriages that could not be explained by known risk f
Procedures for the initial management of children newly diagnosed with diabetes vary greatly worldwide and the evidence available is insufficient for conclusively determining the best process regarding hospital-based or home-based care. The aim of the study was to compare two different regimens for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care (HBH
Organometal halide perovskites have attracted tremendous attention for optoelectronic applications. Charge carrier trapping is one of the dominant processes often deteriorating the performance of devices. Here, we investigate the details of trap behavior in colloidal nanoparticles (NPs) of CH3NH3PbBr3 perovskites with mean size of 8 nm and the corresponding bulk crystals (BCs). We use excitation i
Objective: To assess the mid-term outcomes and feasibility of branched endovascular repair (b-EVAR) of ruptured thoracoabdominal aortic aneurysms (rTAAAs). Methods: All patients undergoing b-EVAR of rTAAAs between 2011 and 2016 were included. Pre-, intra and postoperative imaging was reviewed to assess technical success, outcomes, and feasibility of b-EVAR in the emergent setting. Results: Eleven
Socioeconomic Inequalities in the KidneyTransplantation Process: A Registry-BasedStudy in SwedenYe Zhang, MSc,1Ulf-G.

Few studies have examined the association between individual-level socioeconomic status and access to kidney transplantation. This study aims to investigate the association between predialysis income and education, and access to (i) the kidney waitlist (first listing), and (ii) kidney transplantation conditional on waitlist placement. Adjustment will be made for a number of medical and
Parallel evolution occurs when a similar trait emerges in independent evolutionary lineages. Although changes in protein coding and gene transcription have been investigated as underlying mechanisms for parallel evolution, parallel changes in chromatin structure have never been reported. Here, Saccharomyces cerevisiae and a distantly related yeast species, Dekkera bruxellensis, are investigated be
This dissertation examines Swedish welfare workers’ attitudes towards migrants and migration, their perceptions of welfare work with migrants and organisational working conditions. The dissertation is based on original survey data capturing attitudes and views of welfare workers in two Swedish welfare organisations. The thesis’ conceptual framework draws on three perspectives: street-level burea
This PhD thesis deals with the sub-cycle nature of ultrafast phenomena that occur in strong-field light–matter interactions. As it is of interest to control these phenomena, we must understand them in order to manipulate them. The tools at our disposal are intense laser pulses of short duration, and the systems we study are atoms. A host of exotic phenomena may occur in strong-field light–matter i
Change is sweeping through the world of museums, technologically, financially, and ideologically, impacting on the sociocultural evolution of their roles and status. We seek to contribute to ongoing reflections by offering a conceptual framework that links museums with democratic theory, to citizenship and its practices – a domain that is also in notable transition. We connect concretely with the
The kinetics of sorption of water vapor in mature cement mortar are examined experimentally by the use of a sorption balance (DVS1000). The relative humidity in the sample chamber is obtained by mixing dry and saturated air using flow regulators with very high accuracy. A predefined change of relative humidity in the sample chamber can be obtained in about 30 s. The time needed for equilibration i
von Willebrand factor (VWF) is a plasma protein that consists of a series of multimers of which the high-molecular-weight VWF multimers are the most potent in platelet adhesion and aggregation. The propeptide of the VWF (VWFpp) is known to be essential in the process of multimer assembly. Genetic studies were performed in a patient with a phenotype of von Willebrand disease (VWD) characterized by
