Autoimmune diseases are complex and characterized by the loss of self-tolerance to self-antigens, leading to an immune attack on target tissues of the body. Psoriasis (Ps) and psoriasis arthritis (PsA) are poorly understood autoimmune diseases with unknown genetic and environmental sources. It has been previously demonstrated that a single intra peritoneal injection of mannan induces an acute infl

In nuclear physics, spontaneous fission halflives are central in many areas, such as the study of superheavy nuclei and astrophysical nucleosynthesis. In this thesis, a new method for obtaining spontaneous fission halflives from collective coordinate energy landscapes is proposed, tested, and compared to experimental results. The new method uses the Rayleigh quotient iteration to find the time de

Byggbranschen står för 33% av Sveriges årliga energianvändning. Genom att göra nödvändiga förändringar så som att renovera befintliga byggnader på ett miljösmart sätt kan energi- och miljöbesparingar göras med mer eller mindre enkla medel. I denna studie, som initierades av Trelleborgs Energi AB, undersöktes hur deras kontorsbyggnad kunde bli så innovativ, hållbar och energieffektiv som möjligt. SThe construction industry is responsible for 33% of Sweden’s annual energy consumption. Important environmental and energy savings can be done by renovating already existing buildings with a climate smart mindset. This study was executed on behalf of Trelleborg Energi AB to investigate how their office building can become as innovative, sustainable and energy efficient as possible. The study was a

Ecosystem services from forests provide society with a multitude of benefits. However, current research shows that in Swedish forests aspects of ecosystem services have a status ranging from “moderate” to “inadequate”. The Swedish Environmental Protection Agency set up environmental quality objectives (EQOs) specifically with the aim of identifying environmental problems that need to be addressed

Det här examensarbetet utvecklar ett koncept för infästning av fenor på jetboards som inte intränger på befintliga patent. Det resulterande konceptet medför handlingsfrihet (FTO) och följaktligen tillåter produktion av fenor med originell design. FTO innebär möjligheten till att producera och sälja en produkt utan rättsligt ansvar gentemot ägare av patent. Examensarbetet presenterar och diskuterarThis master thesis generates a concept for the means of attaching fins onto jetboards without infringing on existing patents. The resulting concept establishes freedom to operate (FTO) and enables production of fins with original designs. FTO meaning the possibility of producing and selling a product without legal liability to any patent holders. The thesis further presents and discusses user need

OPO är en viktig strukturerad lipid för bröstmjölksersättning. I denna rapport beskrivs en ny metod för syntes av denna viktiga lipid med hjälp av en tvåstegs-enzymatisk alkoholys-esterifiering. Denna process är komplett med syntes i två steg, intermediär upprening och downstream processing.In this thesis work a simplified, solvent-free, two-step enzymatic method for producing tailored lipids for infant formula with more than 75% of palmitic acid in sn-2 position is described. This simple enzymatic process concept could be a future route towards OPO production or other tailored lipids with palmitic acid in position sn-2

Increasing waste electrical and electronic equipment (WEEE) has become a global issue that raises social and environmental impact concerns, and recycling and using recycled materials is proposed by policymakers and academics as a solution.

The private sector is expected to take ownership and contribute towards achieving the UN’s Sustainable Development Goals (SDGs), and considering the innovative nature of start-up companies, they can be seen as key players. Though, they lack the guidance needed to assess the performance within the SDGs. Moreover, the literature within the field of sustainability assessment tend to focus on larger f

In the early 1980s, during the darkest years of Pinochet’s dictatorship, an apparently innocuous but radical decision was made: to implement an old-age pension system based on individual accounts mandatorily administered by private for-profit entities called ‘pension fund administrators’ (‘AFPs’, by its acronym in Castilian), in which the workers’ social security regarding old-age pensions was in

This thesis seeks to explore an architectural typology that can enhance mental healing qualities in the urban structure. Our modern fast-paced lifestyle has a big impact on our mental well-being and our stress levels are constantly high, while our feelings are continuously exposed to different external factors. This minimizes our ability to understand and process them and to finally get through a

It is now allowed to sell mealworm (Tenebrio molitor) for food consumption, and it will probably play a major role in the search for future protein sources. The climate footprint of the mealworm is considerably smaller than for traditional livestock and is therefore of interest. Insects as human food is fairly unexploited in Sweden and the western world. In connection with the new legislation, an
