B cells play a pivotal role in adaptive immune system, since they maintain a delicate balance between recognition and clearance of foreign pathogens and tolerance to self. During maturation, B cells progress through a series of developmental stages defined by specific phenotypic surface markers and the rearrangement and expression of immunoglobulin (Ig) genes. To get insight into B cell proteome d

However, they fail to address the complex relationships between the conflicting pa
A gardener in Småland, southeastern Sweden, tells that her father cultivated a double daylily, Hemerocallis fulva, with variegated leaves in Stockholm in the mid 20th century. When she moved to Småland, 45 years ago, she brought a piece of his plant with her, and later on she has spread the plant to others. This daylily, known as "Kwanso Variegata", was first found in Japan in 1776, and since then
Recent emission legislation in the marine sector has emphasized the need to reduce nitrogen oxides (NOx) emissions as well as sulphur emissions. The fulfilment of emission legislation limits with conventional marine diesel oil (MDO) requires complex and expensive aftertreatment systems and in this framework lean burn pilot ignited dual fuel (diesel and natural gas) is revealed as one of the most s
Rätten till familjeåterförening stadgas i såväl EU:s Familjeåterföreningsdirektiv som i den svenska utlänningslagen. Principen om familjens enhet, allas likhet inför lagen och barnets bästa är principer av stor vikt inom både internationell, europeisk och svensk rätt. Trots principer som att familjen ska hållas samman och att det ska göras vad som är möjligt för att återförena splittrade familjer,The right to family reunification is regulated in both the Family Reunification Directive of the European Union and in the Swedish Aliens Act. The principles of the family as a unit, all individuals equality towards the law and the child’s best interests, are principles of high importance in International, European and Swedish law.

Background: Today, many companies use a cost-based and sometimes competition-based pricing approach. Since academia agrees that value based pricing is superior for creating profit, the problem is not in identifying an ideal pricing strategy, but to understand and facilitate the transformation process towards value-based pricing. Only a limited amount of research has so far been put on understandin
Water is a large part of life on earth and is also a large part of the human body which is why it is so important. Aquaporins are water channels that transports water through a process called trafficking. Aquaporin 2 is one of these aquaporins and with a faulty trafficking or mutations it could lead to nephrogenic diabetes insipidus and severe dehydration. Ezrin is a protein in the body which FERM
The textile product industry has many challenges and all designers creating products using textiles will have an impact on the environmental sustainability in the world. The project investigates state of the art textile product design today, the challenges of environmental sustainability in the future and how the designer plays a role in making a positive difference. Qualitative research was done
Sweden's compulsive laws are processed by social workers and there are no real guidelines for how the investigations should be assessed. It is up to the social worker to assess a case with the help of the law, the municipality’s policies, and the room for maneuver. The aim of this study was therefore to explore if social workers assess cases differently and what arguments they use in situation
Det finns många svårigheter med att tillverka livsmedelsprodukter som är emulsioner. Syftet med detta projekt var att utveckla en emulsion enligt krav som beställaren av produkten hade satt upp. En första utveckling av produkten skedde ungefär ett år tidigare, och den fortsatta utvecklingen baserades alltså på denna produkt. Det som hade blivit ett problem med den första utvecklade produkten var aIt is a difficult process to create a drinkable food product that is an emulsion. The aim with this project was to create one, containing ingredients on levels described by a customer. A product had been developed before, but resulted in a product that had viscosity that was too high, and the aim with this further development project was to keep the levels of the ingredients on a level according t
Indonesia has implemented national policies and legislations to encourage biofuel production as means to achieve energy security and self-sufficiency and to reduce reliance of fossil fuel reserves. However, there is still no clear road-map for the socio-technological transition. While acknowledging economic impediments, this case study investigates social and political obstacles to bioethanol prod

Machine control with GPS allows machinists to operate using a digital model as reference instead of the traditionally used methods. This leads to other duties and a different flow at the worksite. The purpose of this study is to examine how various professions have changed with the development of machine controlled equipment and also how the work methods can be optimized. A series of interviews ha
