The role of FGFs in the elicitation of different cellular responses
Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

Evaluation of the retinal ON- and OFF-responses in the dog ERG
The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from
their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background.
This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response
(Frishman, 2006; Zrenner and Gouras, 1979).
In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones.
These stimuli gave ERGs with both ON- and OFF-responses.
Procedurellt genererade provinskartor för strategispel : En jämförelse mellan Voronoidiagram och Cellular Automata
Procedurell generering är ett område som vuxit mycket på de senaste åren men som också är ett gammalt område. Kända koncept inom detta område är kart- och terränggenerering. Koncepten används för att skapa både verklighetstrolig terräng och för att skapa spelkartor för spelaren att utforska.Detta arbete använder sig av procedurell generering för att undersöka skillnaden mellan två kända metoder; Voronoidiagram och Cellular Automata vid skapandet av en provinskarta. Tre kartor från varje metod evalueras genom att importeras i spelet Crusader Kings 2 och sedan spelas med hjälp av spelets artificiella intelligens. Kartorna evalueras genom att titta på tre olika faktorer för hur intressant kartan är och prestandan för att skapa en karta.
Kundlojalitet : En studie om hur man skapar lojala kunder inom mobiloperatörsbranschen
The cellular market is today suffering from great customer dissatisfaction. Simultaneously, the services offered by the different cellular providers are very homogenous, causing strict competition where various price strategies have been the main mean of battle. From a business perspective, implementing pricing strategies, to keep up with increased network investments, is a short term solution.In a market characterized by lacking customer satisfaction and harsh competition, research has shown the importance of highlighting customer relations in marketing. This type of marketing, which one could refer to as relationship marketing, is considered an efficient, economic, and strategic method of showing the importance of customer loyalty. To get insight in the relationship between the customers and the cellular providers, as well as to show the importance of relationship marketing, this study has used qualitative interviews to find what develops strong customer loyalty.The results showed that increased customer loyalty is achieved when an emotional bond is created.
EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG
This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Grundläggning med cellglas : En studie av byggtid och lönsamhet
This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.
Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.

Den som sig i leken ger får leken tåla
Social enterprises are increasingly gaining ground as an organisational form in Sweden, however the institutional structures for financing these types of organisations are yet to be established. With its usual origin within the civic society, social enterprises prioritise a higher goal than to maximise economic profit, which often causes these organisations to be dependent upon resources from external constituents within its institutional environment. The aim of this study was to examine how a social enterprise, which derives from the civic society, acts to mobilise resources from constituents in its institutional environment. This was executed through a case study of Jordbro Världsorkester (JVO) - a typical organisation in the civic society which takes the form of a social enterprise - by identifying how assets were used to gain resources in strategic responses to institutional processes and examining how institutional processes affects how JVO acts. Throughout the study, qualitative interviews were conducted with JVO and constituents in its institutional environment and a theoretical framework was developed which explains how capital is used to gain more capital in an emergent strategy of strategic responses as the organisation gets in contact with institutional processes from its institutional environment.
ELever möter Lagerlöf : en responsstudie av gymnasieelevers första möte med en text
This study examines the way Swedish students in Upper Secondary School respond to two excerpts from a classic Swedish novel. The paper?s aim is both to give an overview over some of the theoretical concepts concerning the field of reader-response criticism, and to describe and analyse what the students experience in their first meeting with an older text. The background to my interest is the many studies showing that young readers regard reading of fiction in school as boring. By using the method of written reading responses I want to contribute to a deeper understanding of how an older text can be received, understood and engage its readers.
Prefabricerade passivhusväggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
Jämförande studie av normal ERG-svar hos tre olika hundraser :
The purpose of this study was to compare normal electroretinographies (ERGs) from three different canine breeds in order to evaluate if there were any marked similarities or differences between these breeds as to ERG responses. It is known that healthy dogs from different breeds but also dogs within the same breed but in different age categories may have different appearances of their ERG responses. This may be a problem when evaluating if an ERG is normal or not from a dog within a breed not previously examined. Because of this it is important to obtain normal values for each breed and age group in order to be able to use these for later comparisons of ERGs obtained from individuals affected with various retinal diseases.
In this study we have chosen to examine dogs within the three breeds: Labrador Retriever (LR), English Springer Spaniel (ESS) and Chinese Crested Dog (CCD). All of these breeds may be affected with hereditary retinal diseases such as Progressive Retinal Atrophy (PRA).
It is possible that ERG-responses vary due to a number of different factors.
