Katalysatorer påskyndar en reaktion utan att själva förbrukas; denna mening känner nog många igen från sin skoltid. Andra har hört talas om katalysatorer som något de "har i bilen". Mycket riktigt är det främst i bilar där vi i våra vardagliga liv stöter på katalysatorer. Här används de för att omvandla de mycket giftiga gaserna kolmonoxid och kväveoxid till för människorna ofarligt kvävIn order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase

The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla

Sverige är sedan 1971 ansluten till FN-konventionen om avskaffande av alla former av rasdiskriminering. Konventionen tillkom som en reaktion mot rasdiskriminerande förtryck i form av apartheid och kolonialism. Varje konventionsstat är enligt konventionens art. 4(b) skyldig att olagligförklara och förbjuda organisationer som främjar och uppmanar till rasdiskriminering. Trots upprepad kritik från In 1971, Sweden ratified the United Nations convention on the elimination of all forms of racial discrimination. It was established as a reaction to racial oppression, such as apartheid and colonialism. All state parties are, under article 4, obliged to prohibit and criminalise organisations who in any way promote or encourage racial discrimination. Sweden has, in spite of criticism from the conve

Att förutsäga framtiden – modellering som ett verktyg för att förutsäga vattenkvantitet och vattenkvalitet Inom 100 år så kommer klimatet förändrats avsevärt om utsläpp av växthusgaser fortsätter i samma takt som idag. Detta kommer påverka temperatur, nederbörd vilka i sin tur påverkar flödet av vatten i Sverige. Ett avrinningsområde består av olika jordtyper, vegetation och topografi, vilka allClimate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers. Small streams are the

Sverige har beslutat att år 2020 implementera barnkonventionen och konventionen blir då erkänd som svensk rätt. Barnets rätt att komma till tals i alla förfaranden som berör barnet är en grundläggande princip i barnkonventionen. Norge implementerade barnkonventionen år 2003 vilket resulterade i att barnets rättigheter stärktes. Barnets rätt att komma till tals är lagstadgad i föräldrabalken men t

Denna studie undersökte förhållandet mellan de tre personlighetsdragen som ingår i den Mörka Triaden (Machiavellianism, Narcissism och Psykopati) och attityder gentemot etiska företagspolicies. 114 deltagare deltog i en onlineundersökning som mätte den Mörka Triaden och sju policyfrågor. Deltagarna med de högsta poängen på Mörka Triaden (övre 30 procenten) jämfördes med deltagarna med de lägsta poThis study investigated the relationship between the three personality traits of the Dark Triad (Machiavellianism, Narcissism and Psychopathy) and attitudes towards ethical company policies. 114 participants took part in an online survey, measuring the Dark Triad and seven policy-questions. The participants with the highest scores on the Dark Triad (upper 30 percent) was compared to the participan

Given the current societal and political developments in Germany, the visibility and integration of-marginalized is essential to ensure their inclusion in mainstream society. One way of encouraging-contact between majority and marginalized groups is through building social networks, of which-informal and nonformal educational activities play an important part. This thesis examines the-experience o

Purpose: This thesis analyses and assesses how companies in Germany’s DAX 40 demonstrate their adherence to the UN Sustainable Development Goals. It evaluates whether these disclosures are mainly substantive, indicating proper strategic integration, or symbolic, aimed primarily at enhancing reputation, and compares their reporting quality to previous international research. Methodology: This rese

In a recent experiment, the partial half-life (t1/2) of proton emission from the Iπ = 19/2- state of 53Co was accurately measured. A previous estimate is t1/2 ~ 17 s. The purpose of this thesis was to explain this decay and give a theoretical estimate for the dominating hindrance factors. The angular momentum J in 53Co is coupled to J = 6 for the neutrons, and J = 7/2 for the protons. All of this

The app-industry today is ruled by two giants, namely Android and iOS. For companies and developers, it is essential to deliver their product to the majority of users, thus adapting to both platforms. The platforms involve their own way of developing applications and only barely resembles each other. A problem that the industry faces resides here, having to hire staff with knowledge in either Andr

Small soluble oligomers, as well as dimers in particular, of the amyloid β-peptide (Aβ) are believed to play an important pathological role in Alzheimer's disease. Here, we investigate the spontaneous dimerization of Aβ42, with 42 residues, by implicit solvent all-atom Monte Carlo simulations, for the wild-type peptide and the mutants F20E, E22G and E22G/I31E. The observed dimers of these variants

Abstract: Cardiovascular diseases and diabetes mellitus are closely linked by sharing common risk factors, such as obesity, insulin resistance, hypertension and dyslipidaemia. These intermediate risk factors are affected by the joint effects of environment and genetics. Although a multitude of studies aimed to disentangle the effects of gene-environment interactions, many of the published gene-en

Popular Abstract in Swedish Populärvetenskaplig sammanfattning på svenska Abort är ett av de vanligaste kriurgiska ingreppen i Sverige. 1989 var aborttalet för hela landet 21.5 per 1000 kvinnor i åldern 15-24 år. Storstäderna Stockholm, Göteborg och Malmö har i många år haft det högsta aborttalen, vilka var för dessa 1989 28.4, 27.0 respektive 27.8. De aktuella studierna omfattar de 1466 kvinnorIn Sweden between 32-38,000 women annually elect to terminate pregnancy by means of induced abortion, though their reasons are still not well understood. The purpose of these studies, carried out at the Department of Obstetrics and gynecology and of Community Medicine at University Hospital, Malmö, was to elucidate the incidence of induced abortion in an urban population, with special emphasis on
