This thesis work has focused on the platinum-tin surface, especially how it behaves when exposed to gases like oxygen and carbon monoxide. Platinum-tin is used as a catalyst for a range of reactions, including the oxidation of carbon monoxide at mild conditions, which is important for gas purification in fuel cells. The platinum-tin alloy has properties useful for the reactions it catalyses, but i
Cushioned lipid bilayers are structures consisting of a lipid bilayer supported on a solid substrate with an intervening layer of soft material. They offer possibilities for studying the behavior and interactions of biological membranes more accurately under physiological conditions. In this work, we continue our studies of cushion formation induced by histatin 5 (24Hst5), focusing on the effect o
This study adopts a configurational approach to discover conditions common to graduates from venture creation programs who take a particular learning pathway to high entrepreneurial passion. Our theoretical framework identifies two primary sources of experiential learning (direct and vicarious experience) and three temporal vantage points (pre-, peri-, and post-education) conducive to such conditi
BACKGROUND: Long-term oxygen supplementation for at least 15 hours per day prolongs survival among patients with severe hypoxemia. On the basis of a nonrandomized comparison, long-term oxygen therapy has been recommended to be used for 24 hours per day, a more burdensome regimen.METHODS: To test the hypothesis that long-term oxygen therapy used for 24 hours per day does not result in a lower risk
Dynamic restructuring of silver catalysts during the industrial conversion of methanol to formaldehyde leads to surface faceting and pinhole formation. Subsequent sintering under reaction conditions, followed by increased pressure drop and decreased catalyst activity requires catalyst bed replacement after several months of operation. This necessitates a comprehensive understanding of the bulk cat
Industrial packaging plays an important role in the performance and environmental efficiency of supplychains. Despite it being so important, the implications that industrial packaging decisions have on thelogistics operations (and vice-versa) are not completely understood. This thesis contributes to theunderstanding of the impacts of sustainable industrial packaging by discussing the importance of
BackgroundThis study aimed to investigate the exposure to perfluoroalkyl substances (PFAS) and cancer-related toxicity in workers in different Swedish industry sectors with exposures to hexavalent chromium (Cr(VI)).MethodsThe study consisted of 111 exposed workers and 72 controls. The exposed workers were performing manufacture/processing of metal products (n=55), working in steel production (n=31
The presence of overlapping elements in distinct events promotes the formation of associative inferences across event boundaries, thereby shaping how new information is integrated with pre-existing knowledge. This study investigates the influence of schema congruency on mnemonic processes involved in such associative inferences.The present study employed EEG recordings of brain activity to assess
INTRODUCTION: Symptom distress after heart transplantation (HTx) is a significant problem causing uncertainty, low self-efficacy, and psychological distress. Few studies have addressed self-reported symptoms. The aim was to explore self-reported symptom distress from time on the waiting list to 5 years after HTx and its association with self-reported psychological well-being, chronic pain, and fat
Cadmium telluride (CdTe) solar cell technology is a promising candidate to help boost green energy production. However, impurities and structural defects are major barriers to improving the solar power conversion efficiency. Grain boundaries often act as aggregation sites for impurities, resulting in strain localization in areas of high diffusion. In this study, we demonstrate the use of scanning
Narcolepsy is a sleep disorder caused by an apparent degeneration of orexin/hypocretin neurons in the lateral hypothalamic area and a subsequent decrease in orexin/hypocretin levels in the cerebrospinal fluid. Narcolepsy is classified into type 1 (NT1) and type 2 (NT2). While genetic associations in the human leukocyte antigen (HLA) region and candidate autoantibodies have been investigated in NT1
