A spinel-type catalyst of the composition Fe(2.50(1-z/3))V(0.20(1-z/3))Mo(0.30(1-z/3))square(z)O(4), where z is the number of cation vacancies (El), was prepared under reducing atmosphere. From the reduced sample a number of preoxidized samples were made by TPO treatment of the reduced material to different end temperatures ranging from 150 to 450 degrees C. XRD shows that the spinel-type structur
This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU st
An upcoming trend in the current IT-landscape is to outsource services to so called Cloud Service Providers (CSPs). However, many companies are still sceptical to this new kind of services, since they bring about a certain loss of control. For this reason, it is important for CSPs to show that their services are secure. There are several options in proving this and it is up to every CSP to choose
The size distributions and hygroscopic growth spectra of aerosol particles were measured during the GCE cloud experiment at Great Dun Fell in the Pennine Hills in northern England. Hygroscopic growth is defined as the particle diameter at 90% RH divided by the particle diameter at 10% RH. The fraction of the aerosol particles scavenged by cloud droplets as a function of particle size was also meas
Packaging is one of the logistics areas where there often is potential and even a demand for improvements. An increase in environmental awareness among the population in the European Union (EU) has generated a demand for changes in packaging, which has led to stricter rules and regulations. Knowledge about what regulations are present and what may be expected in the future is crucial in the formin
Background: Free oxygen radicals have been implicated in the pathogenesis of bronchopulmonary dysplasia (BPD) in preterm infants. Superoxide dismutase (SOD) is a naturally occurring enzyme which provides a defense against such oxidant injury. Providing supplementary SOD has been tested in clinical trials to prevent BPD in preterm infants. Objectives: To determine the efficacy and safety of SOD in
BACKGROUND: Parkinson's disease (PD) is a chronic neurodegenerative disorder. There is limited knowledge about the function of the hypothalamic-pituitary-adrenal axis in PD. The primary aim of this prospective study was to analyze diurnal salivary cortisol concentrations in patients with PD and correlate these with age, gender, body mass index (BMI), duration of PD, and pain. The secondary aim was
Att bli förälder är en stor omställning i livet och kan förändra arbetssituationen, relationer och den egna personliga utvecklingen. Föräldraskap upplevs ofta som starkt könsbundet och kvinnor över hela världen tar på sig mer hushållsarbete och barnomsorg än män, även i Sverige. Trots att Sverige har en generös och könsneutral föräldraledighet finns det fortfarande ojämlikheter i hur föräldrar hanThis thesis explored gendered parenthood and parents’ experiences of their work- family interface through the COVID-19 pandemic. This thesis draws on decades of analysis of gendered labor division, father involvement, and the work-family interface to understand developments and tensions before the pandemic. It then positions the pandemic as a global ‘developmental event’ due to the restrictions im
Many people want to play their part to tackle climate change, but often do not know where to start. Carbon Footprint (CF) Calculators pose potential for helping individuals situate themselves in climate impacting systems of which they are a part. However, little is currently known about whether and how individuals who complete CF calculators understand their CF in the context of climate change. Th
BackgroundInterventions that are co-created with end-users, and that are informed by behavior change or implementation theories, support implementation in real world settings. However, injury prevention programs for youth athletes have typically been developed by experts with no, or insufficiently described, end-user involvement and without guidance by theories. The aim of the current study was to
Background: Ice hockey is played by women and men but the arena they play in may differ substantially. Potential differences in general conditions to play the sport may be associated to perceived stress, which has shown to be related to athletic injury in other sports. Therefore, this study aimed to describe and compare general conditions for playing ice hockey, stress levels, and the association
BACKGROUND: To outline how the training program and work situation of residents in Obstetrics and Gynecology (OB-GYN) was affected by the pandemic and to illuminate how residents experienced these changes.METHODS: As part of the COVID-19 in Pregnancy and Early Childhood Staff (COPE Staff) cohort study, between January and May 2021, all participating residents were invited to answer a 28-question o
The support from SSM has made it possible to continue collecting brown algaefrom the place on the Swedish west coast where regular collections began asearly as 1967. The support has also enabled more extensive analyses ofpreviously collected material than was possible before. This applies to bothsupplementary analyses of previously reported radionuclides and analysis ofnew ones. The project has al
Introduction: Roux-en-Y gastric bypass (RYGB) causes more rapid and enhanced absorption of alcohol. RYGB patients have also been reported to use more inpatient care for alcohol-related disease than do patients after other bariatric procedures. The present study was designed to evaluate alcohol consumption level before and after gastric bypass using a sensitive and specific alcohol biomarker. Mater
Context. Pismis 18 is a moderately populated, intermediate-Age open cluster located within the solar circle at a Galactocentric distance of about seven kpc. Few open clusters have been studied in detail in the inner disc region before the Gaia-ESO Survey. Aims. New data from the Gaia-ESO Survey allowed us to conduct an extended radial velocity membership study as well as spectroscopic metallicity
This report presents the sixth version of the European Grassland Butterfly Indicator, one of the EU biodiversity indicators of the European Environment Agency.The indicator is based on more than 9200 transects in national Butterfly Monitoring Schemes covering 22 countries across Europe, most of them active in the European Union. In 2015, counts were made in more than 4500 transects.Butterflies rep
The script we are presenting below is one of four different scenarios from Violence & Learning by Henrik Bromander and John Hanse, which was performed at the International Brecht Society’s Symposium in Oxford in June 2016. The learning play Violence & Learning has been developed and performed in the context of left-wing activism in Sweden. The different variants of the play have partly bee
Resandet med tåg har ökat stadigt i Sverige de senaste 30 åren. Takten har varit cirka två-tre procent per år, och vi nu har mer än dubbelt så många resenärer. Med ökat fokus på klimatfrågan stiger resandet nu ännu snabbare. Ett problem som drabbar både resenärer och företag i Sverige är tågförseningar. Ett sätt att beskriva dessa är den andel av alla tåg som kommer fram mer än fem minuter för sen
Background: Celiac disease (CD) is an immune-mediated inflammatory disease of the intestine in genetically susceptible individuals caused by loss of tolerance to the storage proteins (gluten) in wheat, rye, and barley. Little is known about CD and associated risk factors in Sub-Saharan African countries including Ethiopia. The main aim of the present thesis was to explore how the incidence of celi
