Exposure to low temperatures requires an organism to overcome physiological challenges. New Zealand wētā belonging to the genera Hemideina and Deinacrida are found across a wide range of thermal environments and therefore subject to varying selective pressures. Here we assess the selection pressures across the wētā phylogeny, with a particular emphasis on identifying genes under positive or divers

Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available to plants (although the enzyme itself is strictly microbial). It has been studied extensively with both experimental and computational methods, but many details of the reaction mechanism are still unclear. X-ray crystallography is the main source of structural information for biomacromolecules, but it h

The Cherenkov Telescope Array (CTA), will be the major global observatoryfor very high-energy (VHE) gamma-ray astronomy over the next decadeand beyond. The scientific potential of CTA is extremely broad: fromunderstanding the role of relativistic cosmic particles to the search for darkmatter. CTA is an explorer of the extreme universe, probing environmentsfrom the immediate neighbourhood of black

Syftet med denna uppsats är att undersöka hur mediepubliken uppfattar dagens klimatjournalistik samt vilka positiva och/eller negativa känslor klimatjournalistiken kan skapa. Analysen görs utifrån ett sociologiskt perspektiv. Uppsatsens metod är blandad och innehåller en kvalitativ intervjuundersökning och en kvalitativ innehållsanalys. Uppsatsens intervjuresultat av den kvalitativa intervjuunders

Med en växande global infrastruktur blir det allt vanligare att verksamheter använder olika typer av molntjänster för att underlätta sitt dagliga arbete. För myndigheter, kommuner och andra verksamheter som utnyttjar dessa tjänster till personuppgiftslagring finns det en komplexitet kring hur de ska förhålla sig till lagstiftning och teknik. I den här studien behandlas detta problemområde genom at

We have calculated redox potentials of 12 blue copper protein sites comparing 64 computational methods, systematically varying the quantum mechanics (QM) system size, dielectric constants, density functional, and basis sets. All methods were based on structures optimized with combined QM and molecular mechanics (QM/MM) approaches. The redox potentials were evaluated using 10 quality metrics. The b

Environmental and process control applications have needs for sensors that operate continuously or repeatedly, making them applicable to batch measurement and flowing product stream measurement. Additionally, for lactose monitoring in dairy-processing plants, the sensors must have sufficient flexibility to handle a wide range of substrate concentration and be resilient to withstand wide pH excursi

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide improvements: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protec

Background: Despite uniform operating techniques, lack of fusion still occurs after ankle arthrodesis. Differences in the biological healing potential may be a factor but the mechanical performance of the arthrodesis construct because of varying bone quality also may be important. Internal compression techniques are preferred because of higher union rates, shorter fusion times, and fewer complicat

Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar f

In circumpolar regions, coastlines offer rich constellations of diverse resources, and have long been a focus of human habitation. Despite the rich archaeological records that are located along many northern coastlines, there is a relatively limited understanding of the range of factors that informed local settlement strategies. Northern Norway has one of the world’s longest and best-preserved arc

Background: Ribonucleotide reductases (RNRs) catalyze the formation of the deoxyribonucleotides that are essential for DNA synthesis. The R2 subunit of Escherichia coli RNR is a homodimer containing one dinuclear iron centre per monomer. A tyrosyl radical is essential for catalysis, and is formed via a reaction in which the reduced, diferrous form of the iron centre activates dioxygen. To help und

I samband med att den nya förvaltningslagen (2017:900) (FL) trädde i kraft 2018 så infördes en så kallad dröjsmålstalan genom 12 § FL. Syftet med bestämmelsen är att enskilda ska få ett verktyg för att kunna påskynda handläggningen av ett ärende i det fall som processen präglas av oskäliga dröjsmål. 12 § FL har dock kommit att kritiseras. Redan under remissbehandlingen påpekade ett flertal instansAs the new Administrative Procedure Act came in to force in 2018 a new remedy was introduced to counteract the inaction of administrative authorities. Its aim is to provide individuals with an opportunity to enforce a decision within four weeks when the processing of an errand has been unreasonably delayed. Already during the stage of development, the remedy was criticized for its inability to ful

Enzymes are involved in most reactions in nature. They are important both for the understanding of biological life and for reactions of industrial interest, e.g. in the production of artificial fertilizers, the production of biomass or biofuels. Enzymes with one or several metal ions are called metalloenzymes. In this thesis we study three different metalloenzymes, nitrogenase, lytic polysaccharid

Background: Pressure overload of the heart occurs in patients with hypertension or valvular stenosis and induces cardiac fibrosis because of excessive production of extracellular matrix by activated cardiac fibroblasts. This initially provides essential mechanical support to the heart, but eventually compromises function. Osteopontin is associated with fibrosis; however, the underlying signaling m

The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

As the backbone of the extracellular matrix (ECM) and the perineuronal nets (PNNs), hyaluronic acid (HA) provides binding sites for proteoglycans and other ECM components. Although the pivotal of HA has been recognized in Alzheimer's disease (AD), few studies have addressed the relationship between AD pathology and HA synthases (HASs). Here, HASs in different regions of AD brains were screened in
