People’s ability to learn holds a promise for sustainability as learning is seen to enable change; yet, the prevalence of norms and values in society that reinforce unsustainability may severely challenge this process. The debate on what role learning can play is centered around the question whether people can learn from others and if so, how to enhance it. More precisely, who has to learn what fr
This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour
Background: Hitherto, risk prediction models for preoperative ultrasound-based diagnosis of ovarian tumors were dichotomous (benign versus malignant). We develop and validate polytomous models (models that predict more than two events) to diagnose ovarian tumors as benign, borderline, primary invasive or metastatic invasive. The main focus is on how different types of models perform and compare. M
Background: Cyclin D1 is a well-characterised cell cycle regulator with established oncogenic capabilities. Despite these properties, studies report contrasting links to tumour aggressiveness. It has previously been shown that silencing cyclin D1 increases the migratory capacity of MDA-MB-231 breast cancer cells with concomitant increase in 'inhibitor of differentiation 1' (ID1) gene expression. I
Popular Abstract in Swedish Avhandlingens syfte är att lyfta fram och analysera tre viktiga ämnen inom inombranschhandel; relevansen för efterfrågemönster, distinktionen mellan horisontell och vertikal inombranschhandel, och mätmetoden av inombranschhandel. Kapitel två analyserar inombranschhandel mellan hög- och låginkomstländer, och använder ett teoretiskt ramverk som förklarar bytet av liknandThis thesis aims at shedding light on three important issues related to intra-industry trade (IIT); the relevance of demand patterns, horizontal versus vertical IIT, and the measurement of IIT. Chapter two analyses IIT between high and low-income countries, and uses a theoretical model that explains the exchange of similar products of different qualities. We are particularly interested in the rol
Background: Psychotic illness can have a substantial economic burden not only on the patient and society in general, but also on family members providing informal care (i.e. those not subject to a market wage). While informal caregiving confers benefits for the patient and society, time spent providing informal care is diverted from other activities such as work or leisure. Relatives and caregiver
En central del i de flesta psykoterapeutiska inriktningar utgörs av hur man ser på emotioner samt vilka konsekvenser olika sätt att förhålla sig till eller reglera emotionerna får: Ur ett psykoanalytiskt perspektiv ses primitiva och rigida försvarsmekanismer riktade mot omedvetna affekter, drifter och impulser, som en viktig bidragande faktor till utvecklandet av psykiska besvär (Weiner & BornThe general aim of the present thesis was to further our understanding of cognitive restructuring and acceptance, both as concepts and as psychological processes related to emotion regulation. In doing this, concepts and processes related to cognitive restructuring and acceptance were examined in four different studies using different designs and methodologies. The main purpose of Study I was to
We summarize here the results of a major eight-year investigation of the extraordinarily detailed UV spectrum of the sharp-lined, nonmagnetic, main-sequence, chemically peculiar star chi Lupi (B9.5p HgMn + A2 Vm). The UV observations are composed of 345 Angstrom of the spectrum acquired with the Goddard High Resolution Spectrograph (GHRS) on board the Hubble Space Telescope at an average resolutio
Precipitation suppression due to an increase of aerosol number concentration in stratiform cloud is well-known. It is not certain whether the suppression applies for deep convection. Recent studies have suggested increasing precipitation from deep convection with increasing aerosols under some, but not all, conditions. Increasing precipitation with increasing aerosols can result from strong intera
Corrosion of embedded steel reinforcement is the prime influencing factor that deteriorates the structural performance and reduces the serviceability of reinforced concrete (RC) structures, especially during earthquakes. In structural elements, RC columns play a vital role in transferring the superstructure's load to the substructure. The deterioration of RC columns can affect the structures' over
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
Groundwater is Earth’s largest liquid freshwater resource. It is a significant component of the hydrological cycle and a buffer that sustainsrivers and freshwater-dependent ecosystems during droughts. Approximately half of the world’s population depends on groundwater fordrinking water, food, and hygiene. It is used extensively in agricultural irrigation, food production and for industrial process
Natural killer (NK) cells represent the cytotoxic member within the innate lymphoid cell (ILC) family that are important against viral infections and cancer. Although the NK cell emergence from hematopoietic stem and progenitor cells through multiple intermediate stages and the underlying regulatory gene network has been extensively studied in mice, this process is not well characterized in humans
Artificiell intelligens (AI) är ett växande teknologiskt fenomen som inom en snar framtid spås kunna skapa kreativa verk i form av romaner, konstnärliga bilder, musik, m.m. likvärdiga de verk människor skapar. Till skillnad från mänskoskapade verk kommer AI-alstren inte omfattas av upphovsrätt eftersom upphovsrätten endast skyddar det som skapas av människor. Genom att studera upphovsrättens motiArtificial intelligence (AI) is a growing technological phenomenon that is predicted to, within the near future, be able to create creative works such as novels, artistic pictures, music, and the likes, equivalent in quality to the works of humans. As opposed to the works made by humans, AI-creations will not be protected by copyright, as copyright is limited to things made by humans. By studying
Sweden has traditionally pursued a restrictive policy on alcohol. One of the fundamental and outstanding features of this policy is the monopolization of the retail sales of alcoholic beverages. Spirits, wine and beer with an alcohol content of more than 3.5 per cent by volume may only be sold by the State-owned Systembolaget AB. The products available in Systembolaget's shops are selected and
BACKGROUND: Chronic low-grade inflammation may play a role in the pathophysiology of depression, at least in a subset of patients. High-sensitivity C-reactive protein (hs-CRP) has been used to define an inflamed subgroup of depression with specific clinical characteristics and symptoms. In this study we investigated biochemical and clinical characteristics in patients with difficult-to-treat depre
The aim with this bachelor thesis is to analyse the debate regarding Adam of Bremens depiction of the famous Uppsala-temple within contemporary archaeological research, with the purpose to determine how the scholars have approached the question about the credibility and truth of the depiction. The purpose does also include examining the main viewpoints and their arguments within this debate. The q
INTRODUCTION: Central venous catheters (CVCs) are essential in modern healthcare. Insertion of a CVC promotes a hypercoagulable environment, in part through activation of the intrinsic coagulation pathway. We have previously shown that blood obtained from newly inserted CVCs demonstrates immediate coagulation activation, with differences between samples collected directly after insertion and after
