Odlingsmedium : Att ersätta fetalt kalvserum med ett kemiskt definierat substitut
SammanfattningProjektgrupp 14-X5 avser med denna rapport att ge avdelningen Bioreagens på Thermo Fisher Scientific ett underlag för att på sikt kunna byta ut fetalt kalvserum (FCS) mot ett kemiskt definierat suplement vid odling av mushybridomceller för produktion av monoklonala antikroppar. Thermo Fisher Scientific är ett världsomspännande bioteknikföretag som utvecklar blodtestsystem som stöd för klinisk diagnos och uppföljning av allergier, astma och autoimmuna sjukdomar.Fetalt kalvserum är en tillsats i många odlingsmedier som ofta är nödvändig för att cellerna ska växa. Det finns dock många problem med FCS. Det är en biprodukt av köttindustrin och produceras på ett etiskt tveksamt sätt, variation mellan olika batcher förekommer och då det är en animalisk produkt finns en risk för kontamination av bland annat bakterier, virus och prioner. Av dessa anledningar vill man byta ut FCS mot ett kemiskt definierat, serumfritt supplement.

Obalans mellan rot och krona skapar omplanteringschock i Prunus avium :
In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..
Swedish SME Financing - Evidence from the Game Industry
The objective of this thesis is to examine the capital structure of Swedish small and medium sized enterprises (SMEs). Accounting data from Swedish game developers, combined with the result from a survey, is used to examine their financial conditions and capital structure decisions. We find that non-debt tax shield, firm size, growth opportunities and age are, to various extents, the determinants of capital structure in the game industry, while effective tax rate and asset structure have marginal effects. Our study also implicates that most of the existing capital structure theories can explain SMEs leverage decisions to some extent; however, some adaptation is needed to fit these theories into the SME context. Additionally, we find the existence of a financial gap in the game industry which might need efforts from both demand side and supply side to eliminate..

Norrländsk känsla för Japan
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).
En lycklig omställning av Sverige
This paper aims to examine how and to what extent, a transition of Sweden according to the principles of Omställning Sverige (Transition towns Sweden), have the potential to contribute to a society with increased happiness.The paper is based on a qualitative textual analysis of the key texts in the Swedish Transition towns movement, Omställning Sverige. In the first part of the study the most important transition principles of Omställning Sverige were identified. Four key principles emerged: An altered view of economics, a spiritual change, a stronger local community and increased awareness. These transition principles were then analyzed through the lens of the scientific fields position on happiness, followed by a summarizing conclusion.The altered view of economics which Omställning Sverige advocates, where sustainability and quality of life are priorities over economic growth, is even necessary to secure our basic physiological needs. Such an economy has also improved conditions for economic stability, high employment and higher efficiency in the sense of happiness promoted in relationship to how many natural resources are used.

OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
