The active site of the [FeFe] hydrogenases contains two Fe ions bound to one Cys ligand, three CO molecules, two CN(-) ions, and a dithiolate ligand. The nature of the last of these has been much discussed, and it has been suggested that it contains C, N, or O as the bridgehead atom. Most experimental studies indicate a N atom, whereas a recent density functional theory (DFT) study of a crystal st
In the scientific domain of high energy physics (HEP), the Worldwide LHC Computing Grid (WLCG) was created in order to handle the huge compute and storage needs of the experiments at Large Hadron Collider (LHC). Today WLCG combines about 1.4 million computer cores and 1.5 exabytes of storage from over 170 sites in 42 countries. What ties the sites together is the middleware installed at each site,
Soil and groundwater contamination is an increasingly recognised threat to public health and the environment around the globe. New types of contaminants continue to emerge, and awareness of their threat, continues to develop. Many countries have national clean-up programs with priority lists of the most hazardous contaminated sites. Investigation and remediation of these sites, however, take a lon
This diploma work has been performed in collaboration with Johnson Matthey, a company supplying catalysts and technologies, such as formaldehyde plants and catalysts. The aim of the master thesis project was to investigate if and how water impacts the partial oxidation of methanol to formaldehyde over a FeMo-catalyst. The investigation covers how water affects the selectivity to the main product a

Generalist parasites experience selective pressures from the various host species they infect. However, it is unclear if parasite transmission among host species precludes the establishment of host-specific adaptations and population genetic structure. We assessed the population genetic structure of the vector-transmitted avian haemosporidian parasite Haemoproteus majoris (lineage WW2; n = 34 infe
The bone material from three archaeological occupation phases at Huseby Klev provides the best source of evidence currently available about the subsistence strategies of pioneer settlers in Northern Europe. The results from Huseby Klev indicate that the pioneer settlers initially relied heavily on marine mammals for their sustenance. This subsistence strategy changed during the second and third oc
Bakgrund: I bygg- och anläggningsbranschen skedde 1470 olyckor år 2018 där några även ledde till dödlig utgång (Arbetsmiljöverket, 2018). Utbildningen till maskinförare idag är både lång men grundlig och ger maskinföraren de förutsättningar som krävs för att framföra ett anläggningsfordon på ett säkert sätt på en byggarbetsplats. Genom regleringar från arbetsmiljöverket och förebyggande åtgärder aBackground: In the construction industry a total 1470 accidents occurred 2018 where some of them also led to fatal outcome (Arbetsmiljöverket, 2018). The qualification to be a construction machine operator are both long and thorough and will give the operator the prerequisites to convey the construction machine in a safe way on different construction sites. Through regulations from Arbetsmiljöverk
Fourteen tree-ring chronologies developed from 788 peatland Scots pines sampled at sites in Estonia, Belarus and Sweden were compared for common growth trends and possible links to regional climate dynamics. Several synchronous growth release events were detected, especially during the 1910s, 1930s, and around 1970 and 1990, indicating that hydrological shifts and associated tree growth responses
With their highly sensitive visual systems, the arthropods have evolved a remarkable capacity to orient and navigate at night. Whereas some navigate under the open sky, and take full advantage of the celestial cues available there, others navigate in more difficult conditions, such as through the dense understory of a tropical rainforest. Four major classes of orientation are performed by arthropo
There are many projects in Mozambique for poverty reduction. One of these projects is funded by Millennium Challenge Account (MCA) and is aimed to install a total of 600 rural water points in the provinces of Nampula and Cabo Delgado. Each water point consists of a drilled well, a water pump and a communal washing basin. Vertical Electrical Sounding (VES) was used for assessing the uitability of
In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the a
In silico tools for splicing defect prediction have a key role to assess the impact of variants of uncertain significance. Our aim was to evaluate the performance of a set of commonly used splicing in silico tools comparing the predictions against RNA in vitro results. This was done for natural splice sites of clinically relevant genes in hereditary breast/ovarian cancer (HBOC) and Lynch syndrome.

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.

The study investigates how the Best Interests of the Child principle in the UN Children's Rights Convention (Article 3) has been adapted in custody disputes in Egypt, Sweden, and Uzbekistan. Although the Convention on the Rights of the Child offers a common normative benchmark, divergent legal cultures shape its domestic meaning: Egypt is governed by religious and state legal norms intersecting wi
Summary: The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded
I augusti 2004 föddes det första barnet i TEDDY-studien. Föräldrarna informerades om att barnet hade en förhöjd ärftlig risk för autoimmun (typ 1) diabetes och de samtyckte till att komma på ett första besök när barnet var 3–4 månader gammalt. Detta inträffade i december 2004. Forskningssjuksköterskan Gertie Hansson tog då ett blodprov på en tre månader gammal, helt frisk bebis utan diabetes i fam

The effects of input data uncertainty on the critical loads and exceedance estimates for Swedish forest soils was assessed using Monte Carlo simulations of the PROFILE model. The study focuses on the effects of data uncertainty on the 5%-ile critical load at 150 × 150 km resolution and the 95%-ile exceedance at 150 × 150 km and 50 × 50 km resolution. The results indicate that data uncertainty limi
This study compares the performance of different models used to assess the local wind near-surface conditions at an agricultural site in Scania, southern Sweden. The methods are: (a) the WASP model (Wind Analysis and Application Program), (b) separate linear regressions of the two wind vector components, (c) a regression model based on vector correlation, and (d) linear regression of scalar wind.
