How do ’clandestine’ asylum seekers experience the Swedish welfare state? How are they located in relation to welfare institutions, civil society, notions of nationhood and gender regimes? My research project is based on an ethnographic study with ‘clandestine’ asylum seekers (rejected asylum seekers who stay in the country and ‘hide’ from police and authorities to avoid deportation) and asylum r

Popular Abstract in English Alcohols and aldehydes are used in the chemical industry largely as a starting material for the manufacture of a wide range of products. They are also used as such in various industrial applications. The flexibility is due mainly to the functionalities of the alcohols and aldehydes being hydroxylic and carbonylic, respectively. Much interest is directed nowadays at convNowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan

Irradiating a flame by microwave radiation is one of several plasma-assisted combustion (PAC) technologies that can be used to modify the combustion chemical kinetics in order to improve flame-stability and to delay lean blow-out. One practical implication is that engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. In additi

My first encounter with a begging person led me to spend five years investigating the new situation regarding begging and giving in Sweden. The premise is that every-day actions and reactions to another person can be made visible through aesthetics with ethical underpinnings. My investigation takes place mainly in the urban landscape and in the media. The images always constitute the point of depa

Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress at h

A statistical study of data containing observations of process and quality variables from the SCA paper mill in Munksund, Sweden, is presented. The emphasis in this analysis has been on modelling the laboratory collected paper quality variables by means of the data available on-line, during production. The primary tool for prediction, or estimation at non observed time instants, of variables was

Biorefineries are rapid growing branches in the world of sustainable chemical engineering, and one aspect that becomes more and more important is the reuse and valorization of different by-products. In sugar mills, molasses is a low value by-product mainly used for animal feed. However, a large part of the molasses contains the main product of the sugar mill: sucrose. By using membrane filtration,

Chronic obstructive pulmonary disease (COPD) is a progressive life-threatening disease that is significantly increasing in prevalence and is predicted to become the third leading cause of death worldwide by 2030. At present, there are no true curative treatments that can stop the progression of the disease, and new therapeutic strategies are desperately needed. Advances in cell-based therapies proTo date, bone marrow-derived mesenchymal stromal cells (MSCs) have been considered the golden standard among MSC cell-based therapies. However, the harvesting of bone marrow is a highly invasive procedure and the number of MSCs isolated is low, and it declines with increasing age. MSCs with immune-regulatory and regenerative properties can be isolated from many different tissues; however, bone mar

A commercially available fuel, E85, a blend of ~85% ethanol and ~15% gasoline, can be a viable substitute for fossil fuels in internal combustion engines in order to achieve a reduction of the greenhouse gas (GHG) emissions. Ethanol is traditionally made of biomass, which makes it a part of the food-feed-fuel competition. New processes that reuse waste products from other industries have recently

Climate change is an issue that can no longer be ignored and actions are taken all over the world in order to prevent the effects from becoming too severe. The energy system is transitioning towards more renewable energy sources and wind power has an important role in this development. The penetration of wind power in a lot of countries all over the world has increased rapidly during the last deca

Agriculture is an essential economic activity which sustains the livelihood of millions of people around the world. Maize is one of the most grown, consumed and traded cereals in the world mostly because of its adaptability to varied environmental conditions. Maize farming depends on climatic factors like temperature, rainfall and radiation to thrive but this also means that it is very susceptible

Purpose: The fundamental aim of this thesis is to investigate how strongly the Personalized Marketing (PM) factors identified in previous literature correlate with millennials’, aged 24 to 40, intention to act upon personalized advertisements on Facebook. Thereafter, the goal was to compare the extent to which the outcomes varied depending on millennials' age group and gender. Methodology: The

Previous studies have pointed to a need for further research regarding young women with autism and post-traumatic stress disorder (PTSD) or experiences of trauma, especially within psychiatric social work. The aim of this study was to examine how social workers reflect on their experiences and knowledge of trauma among young women with autism. Furthermore, the aim was to deepen the understanding o

This thesis purpose is to look at British media’s coverage of Chinese developmental involvement in Africa, particularly at how the most-read newspapers in the UK have written about the situation, and how they have used media framing when reporting on it. As media can have an enormous impact on people’s perception of certain situations, this paper’s aim is to analyse the media discourse and offer a

En stor del av narkotikaförsäljningen sker idag via internet och distribueras genom det nationella postflödet där köpare inte sällan får hem försändelserna direkt i sin brevlåda. Mot bakgrund av detta föreslår 2021 års postlagsutredning (SOU 2021:29) ökade möjligheter för de brottsbekämpande myndigheterna att förhindra denna illegala handel. Utredningen föreslår bland annat att ge personal inom poA vast amount of drug sales take place daily via the internet and is distributed through the national postal system, where buyers often receive the items to their mailbox. Considering this, the Swedish Government appointed a new Committee to review the duty of confidentiality in the Postal Services Act (2010:1045) in order to increase opportunities for the law enforcement authorities to prevent th

In Sweden, there is a great demand for construction. At the same time, construction companies must increase their profitability. This requires the development of systems for improved communication and interaction. Especially now when the industry is facing massive retirements, there is a risk that knowledge will be lost. To ensure quality the companies also need to involve their employees so they
