In recent years there has been much attention paid to corporate scandals, and in the Swedish media the Skandia incidents have become a serial as, years after the incidents was revealed, sentences are passed on those involved in the scandal. The former president and vice president of the joint-stock company Skandia were both prosecuted for the economic crime gross breach of faith committed by an ag

Instrumental analysis in metabolomics has proven to be a challenging topic due to metabolites having a wide spectrum of physiochemical properties and concentrations. The more conventional techniques in metabolomics include gas chromatography and liquid chromatography coupled with mass spectrometric (MS) detection. In most cases these techniques provide methods that are adequate for metabolomic res

This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th

Potato protein is an industrial side product with highly desirable properties which can be utilized if the toxic glycoalkaloids can be removed in a gentle way which doesn’t damage the protein. The challenge within this project is to find an extraction technique efficient enough to remove the toxic glycoalkaloids, but still mild enough to preserve the protein from denaturation. Supercritical CO2 ex

The positive correlation between elevated expression of wingless-type mammary tumor virus integration site family member 5A (WNT5A) and metastatic potential in melanoma has been extensively explored. However, detailed mechanistic aspects regarding how WNT5A promotes increased melanoma aggressiveness remains unknown. Myristoylated alanine-rich C-kinase substrate (MARCKS), an intracellular protein c

Sammanfattning Detta arbete har delats in i två delar. Den första delen handlar om olika energilagringstekniker. Den andra delen handlar om att lagra egenproducerad elenergi i ett flerbostadshus. Syftet med första delen har varit att samla information om olika energilagringstekniker i en kunskapssammanställning genom att studera dess funktion, aktuella status och framtidsutsikter. Den andra delen Abstract This master thesis is divided into two parts. The first part deals with a general study of different energy storage systems. The second part deals with the possibility to store own-produced electricity from solar panels in a multifamily residential area. The purpose of the first part was to collect information about different energy storage systems in a general study, and examine their di

Besides bone marrow, the kidneys are often dose-limiting organs in internal radiotherapy. The effects of high-linear energy transfer (LET) radiation on the kidneys after alpha-radioimmunotherapy (alpha-RIT) with the alpha-particle emitter, At-211, were studied in nude mice by serial measurements of the glomerular filtration rate (GFR). The renal toxicity was evaluated at levels close to the dose l

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of root s = 7 TeV corresponding to an integrated luminosity of 38 pb(-1). Jets are reconstructed with the anti-k(t) algorithm with distance parameters R = 0.4 or R = 0.6. Jet energy and angle corrections are determined fr

Background: B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. Methods: We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, includ

BACKGROUND: For reasons that remain unclear, surgery for Graves' disease is associated with a higher risk of hypocalcemia than surgery for benign atoxic goiter. In the present study, we evaluated risk factors for postoperative hypocalcemia in patients undergoing operation for Graves' disease. METHODS: Data from 1,157 patients who underwent operation for Graves' disease between 2004 and 2008 were

Background: The widening socioeconomic gap in smoking during pregnancy remains a challenge to the Swedish antenatal care services. However, the influence of cultural factors in explaining the socioeconomic differences in smoking during pregnancy is not clear among the immigrant women. The aim of this study was to investigate whether the development of smoking prevalence among pregnant immigrant wo

Kuannersuit Glacier, a valley glacier on Disko Island in west Greenland, experienced a major surge from 1995 to 1998 where the glacier advanced 10.5 km and produced a similar to 65 m thick stacked sequence of debris-rich basal ice and meteoric glacier ice. The aim of this study is to describe the tectonic evolution of large englacial thrusts and the processes of basal ice formation using a multipr

Background: Ischemia-reperfusion (I/R) in the intestines is an inflammatory condition which activates leukocytes and reactive oxygen species (ROS) and leads to lipid peroxidation and DNA damage. Bilberry and chokeberry fruits are rich sources of polyphenols which may act as antioxidants and prevent lipid peroxidation. Lactic acid bacteria (LAB) may improve microbial status in the intestines and in

Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri

Background: A potential dual role of folate in colorectal cancer (CRC) is currently subject to debate. We investigate the associations between plasma folate, several relevant folate-related polymorphisms, and CRC risk within the large European Prospective Investigation into Cancer and Nutrition cohort. Methods: In this nested case-control study, 1,367 incident CRC cases were matched to 2,325 contr

Background: Obstructed labour is still a major cause of maternal morbidity and mortality and of adverse outcome for newborns in low-income countries. The aim of this study was to investigate the role of individual and health facility factors and the risk for obstructed labour and its adverse outcomes in south-western Uganda. Methods: A review was performed on 12,463 obstetric records for the year

Introduction Aniridia (iris more or less missing), is a congenital, dominant, inherited, serious and sight-threatening disease, most often appearing as an isolated eye disorder. It is caused by mutations in the PAX6 gene, the master gene of the development of the eye. Typically, Aniridia causes severe visual impairment. In addition to glare caused by the iris defect, underdevelopment of the macula

Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address the possibility of accessing nucleon-to-pion (pi N) TDAs from (p) over barp -> e(+)e(-)pi(0) reaction with the future PANDA detector at the FAIR faci
