Popular Abstract in English In the modern world of today, we are surrounded with many electronic devices which offer previously unseen performance. These devices constitute a large part of the everyday consumer electronics such as laptops, tablets, smart phones, etc., but are also used in wide variety of domains such as automotive industry, avionics, medicine, etc. The constant demand for high perIncreasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. The time overhead is particularly important for a group of computer systems referred to as real-time systems (RTSs) where correct operation is defined as producing the correct re

Popular Abstract in Swedish Inledning: Stroke är en av de största folksjukdomarna. En patient med akut stroke behöver medicinsk omhändertagande vid en vårdenhet med specialkunskap. För att så tidigt som möjligt kunna planera omhändertagande och ta ställning till behandling är tillförlitlig diagnostik i akutskedet viktig. Cirka 20% av patienter med stroke har en blödning. Hjärnblödning diagnosticerPurpose: To compare the visualization of small ischemic brain lesions using diffusion using diffusion-weighted (DW) MRI and conventional imaging, with special regard to diagnostic efficiency. Imaging features of lesions of different ages, diagnostic limitations and technical principles were also investigated. Methods: All studies were performed with the same 1.5 T MR scanner. In the first study t

Popular Abstract in Swedish Finkorniga moräner betraktas ofta som problemjordar inom anläggningsbranschen beroende på jordarnas känslighet för förändringar i vatteninnehåll och för deras tjälegenskaper. I dagsläget används endast en begränsad mängd finkorniga moräner i anläggningsbyggande. Huvudmålet med denna avhandling har varit att öka kunskapen om dessa jordars egenskaper och att finna/utvecklFine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. The main objective of this thesis is to improve the knowledge of how to use and also treat a fine-grained till, so that a greater amount can be utilised as earthwork material. To achieve an increasin

Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. CDH consists of a flavin containing catalytic domain (DH) and a haem containing electron mediating domain (CYT).

Type 2 diabetes is one of the world’s major challenges today. Over 400 million people around the globe are diagnosed with diabetes and the consequences to the individual patient and health care systems are significant. Diabetes is a chronic disease and the standard treatment including lifestyle changes, metformin and insulin is in many cases not effective enough. New anti-diabetic drugs have been Type 2 diabetes is one of the world’s major challenges today.

Regulation of development and entry into sporulation is critical for fungi to ensure survival of unfavorable environmental conditions. Here we present an analysis of gene sets regulating sporulation in the homothallic ascomycete Ashbya gossypii. Deletion of components of the conserved pheromone/starvation MAP kinase cascades, e.g., STE11 and STE7, results in increased sporulation. In kar3 mutants

Proteins are large, complex molecules that play many critical roles in the body and are required for the structure, function, and regulation of the body’s tissues and organs. In very simple terms, a protein can be defined as a linear chain of subunits called amino acid residues. The individual amino acid residues are sequentially bonded together by peptide bonds. There are 20 standard amino acids This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. Both, Metropolis Monte Carlo and m

High concentrations of salts in agricultural soils are an environmental problem that has plagued human civilization from its very beginning. Already the earliest civilizations in ancient Mesopotamia struggled with increasing concentrations of salt on irrigated fields. Also in modern times, salinization of soils, particularly of agricultural soils is still a problem restricting agricultural productSoil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

As technology progress the right to personal integrity has been discussed in several areas. One of those areas is labour law and specifically the employee’s right to personal integrity. As communication becomes more and more digital it has become more practical for employers to monitor their employees. The question regarding employees’ right to protection for their personal integrity is, despite

Many studies have over the years utilized gravity models derived from trade theories to investigate how various factors affect trade in agricultural goods. Although technological improvements could be considered in such models, few studies have considered this topic in depth, leaving a void to fill. To partly fill this void, this study has chosen the silk sector to analyze the impact of technologi
