Popular Abstract in Swedish Vad är det för något i human mjölk som dödar cancer celler? Kan “fel” veckade proteiner vara nyttiga? Kan fett vara inblandat i protein veckning? Det är några av frågorna som tas upp i denna avhandling. Allt levande består av proteiner som i sin tur är uppbyggda av amino syror. Det finns 20 st. olika amino syror som på olika sätt kan länkas samman till proteinkedjor. D
The active site of sulfite reductase (SiR) consists of an unusual siroheme–Fe4S4 assembly coupled via a cysteinate sulfur, and serves for multi-electron reduction reactions. Clear explanations have not been demonstrated for the reasons behind the choice of siroheme (vs. other types of heme) or for the single-atom coupling to an Fe4S4 center (as opposed to simple adjacency or to coupling via chains
During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a
Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc
Rising sea level is very frightening and can cause huge amount of damage, thus coastal protection is vital for protecting infrastructure, coastal environments and human lives against flooding. To build effcient coastal protection one has to know the magnitude of the flood. Usually one has little information of flooding since they don't occur very often, hence it can be hard to know how to bCoastal protection is vital for protecting infrastructure, coastal environments and human lives against flooding. Building ecient coastal protection requires a good understanding of maximum sea levels which might occur indifferent time periods in the future. Extreme value theory provides a mathematical framework for such analyses. On November 13, 1872 the biggest recorded sea level surge devastat
Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researchedMillions of stars litter the night sky, and our understanding of how they were born is still developing. These burning orbs of gas are so far away that even the light they give off takes years to arrive to us on Earth. So how are we to measure anything about them if sending any equipment to their distant locations is unimaginable? Since the days of Newton, the only way we have been able to say any
The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. Three methods with different structural complexity were used to estimate the adverse effects of SO2 concentrations in northern Czech R
International Development and Management - Master of Science programme Information about programme-specific documents Apart from the general documentation required by the Swedish University Admissions, you must also submit several programme-specific documents. This document contains information about how you can apply for the programme and which documents you need to submit in your application. Pl
As the global population continues to grow and the demand for clean drinking water in-creases, the importance of a functioning water distribution network becomes evident. In the design and planning phase of a distribution network, a hydraulic model is a helpful tool for predicting consequences of an action and defining vulnerable parts of a network.

This paper presents a millimeter-wave (mm-wave) phase-locked loop (PLL), with an output frequency centered at 54.65 GHz. It demonstrates a mode-switching architecture that considerably improves the lock time, by seamlessly switching between a low-noise mode and a fast-locking mode that is only used during settling. The improvement is used to counteract the increased lock-time caused by cycle-slipsThis paper presents a millimeter-wave (mm-wave) phase-locked loop (PLL), with an output frequency centered at 54.65 GHz.

Business opportunities are a chance for a company to grow its activity and to further the aggregate welfare of the society as a whole. Corporate opportunities rules and their functional equivalents should enable companies to develop their business activities when directors discover those business opportunities.

Studiens målsättning har varit att ur ett energibesparingsperspektiv samt ekonomiskt perspektiv utvärdera termostatiska cirkulationsventiler (termiska ventiler) som används i varmvattencirkulation (VVC). De frågeställningar som belystes i studien var hur värmeförluster från VVC med termiska respektive fasta ventiler varierar, om det är ekonomiskt lönsamt att installera termiska ventiler jämfört meThe study's objective was, from an energy-saving and economical perspective, evaluate thermostatic circulation valves (thermal valves) used in hot water circulation (HWC). The issues that have been highlighted in the study were how the heat losses from HWC with thermal valves varies from HWC with fixed valves, whether it is economically viable to install thermal valves compared to fixed valves
When a child's parents are divorced or separated and violence has occurred between them, several problems can arise in custody cases. The purpose of this thesis is to study these problems and the possibilities to solve them. The first problem I study in this thesis is the different parties' rights which often rise in opposition to one other. These rights refers to the abused parent's r
When being in a noisy environment, a normal hearing person can manage to sort out background noise and focus on the attended source. This is something that a person with impaired hearing will struggle with, even when wearing a hearing aid. Research for developing intelligent hearing aids has not yet come up with a solution for solving this problem and more research is needed. This thesis uses data
Uppsatsen belyser den problematik som omfamnar ensamkommande barns rätt till uppehållstillstånd i Sverige genom synnerligen ömmande omständigheter, särskilt med tanke på lagändringen i december 2023 som gör det svårare för barn att få uppehållstillstånd beviljat. Detta bekräftas även av statistiken som visar att en betydande minskning av beviljade ansökningar skett året efter lagändringen. UtvecklThe essay highlights the issues surrounding unaccompanied minors' right to residence in Sweden under "particularly distressing circumstances," especially in light of the legislative change in december 2023 that makes it more difficult for children to be granted residence permits. This is confirmed by statistics showing a significant decrease in approved applications in the year follo
