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.
Barnets talan - en studie om beaktandet av barnperspektiv i den svenska Migrationsdomstolen : / The voice of a child - a study regarding a child perspective in the Migration Court of Law in Sweden
The following essay examines the conditions of whether a child perspective is recognised in the second authority of the new Swedish asylum process, the Migration Court of Law and inquire into the viewpoint of these decision makers as to what a child perspective in this context represents.The method used was a qualitative study that contained interviews with eight respondents, divided into four judges and four jurors. The material gained from the respondents was then analysed by using theories regarding a child perspective and theories that deal with interpretation of a text, ethics and court sociology.A few conditions of whether a child perspective is recognised has been revealed and we also found that the child perspective in theory is a wide perspective, that includes many aspects of how a child is recognised. In practice, however, the child perspective can be divided into two separate perspectives where one of them involves an adults view of a child?s perspective, and the other involves the perspective of a child, the child?s own view of its existence and perceived reality..
Tyst Motarbete? : En studie om kvinnor i styrelsen påverkar avkastning på kapitalet.
ABSTRACTTitle: The exact title used in the thesis will be mentioned here.Level: Bachelor thesis in BusinessAuthor: Mattias Lindqvist & Jonas TesfaySupervisor: Peter LindbergDate: 2011 ? JuneAim: In Sweden the representation of women on company boards is discussed extensively. It has also been suggested that regulations such as quotas should be imposed, in hopes of getting the gender balance on the board of directors. Measures such as these have been presented when this problem attacks our democratic values about how a society should look like. The aim is to study and analyze whether there is any connection between the return on assets and the proportion of women on company boards.Method: The paper is made from a quantitative with a deductive approach.
Passage efficiency and migration behavior for adult Atlantic salmon at a Half-Ice Harbor fish ladder
Due to exploitation of the world?s rivers, the upstream migration of anadromous species is frequently delayed or even prevented. To mitigate these problems and allow fish to migrate past obstacles, structures such as fish ladders have been developed. However, recent studies show that many of the present fish passage facilities are deficient. Monitoring and evaluation of passage facilities is therefore crucial to enable necessary adjustments.
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
Hur påverkar ålder och fetthalt laxsmoltens utvandring till havet?
AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.
Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem
Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.
Migrationspolitik och xenofobi : En studie av emigranters och flyktingars rättigheter i Grekland
AbstractThe purpose of this study is to examine how Greece?s migration system functions and how immigration and asylum policies manifest themselves during the countries current severe economic crisis. More precisely, examining how the regulatory framework and policies regarding refugees' and migrant situation effects practical implementation. The research questions raised are; - How are refugees and other migrants' rights in Greece respected, from a legal, political and moral perspective? What impact can racism have on the treatment of refugees and other migrants? A contextual analysis of ideas through an analysis of the political programs/agendas was used and contrasted, through theories concerning racism, nationalism and globalization to further nuance the situation concerning refugees' rights.
Strategi, syften och visioner för intranät : av intranät i samband med uppgradering.
Intranets can streamline workflow processes, improve communication and add value to the employees of an organization. Companies that don?t take advantage of the potential in their intranet is a common phenomenon. In connection with a migration project dealing with a switch of content management system it turned out that SAS Technical Services lacked clear objectives and strategies for the use of their intranet. Thereby they didn?t make the most of the possibilities an intranet brings.The work with this thesis began with collecting the experiences the company could take with them from the migration project.
Helicobacter spp. i digestionskanalen hos svenska katter : en metodologisk och klinisk studie
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.
Växande Befolkningsklyftor i ett ständigt föränderligt samhälle - Västerbotten 2000-2014
REFERATStudiens syfte är att påvisa utvecklingstrenderna i befolkningens utveckling och sammansättning under perioden 2000-2014. Syftet är också att diskutera denna utveckling utifrån teorier och trender i ett större perspektiv.Studien är kvantitativ och bygger på datamaterial från SCB. Studien är en deskription för hur befolkningsutvecklingen och sammansättningen av ålder och könsbalans ser ut för kommunerna i länet.Resultatet visar att de flesta kommuner har en negativ utveckling och att nästan all befolkningstillväxt sker i Umeå. För samtliga kommuner minskar andelen yngre och andelen äldre blir fler. Åldersstrukturen, könsbalansen och försörjningskvoten skiljer sig kraftigt mellan kommuner.
Kommunal befolkningsförändring : En studie av mellankommunal migration och dess bakomliggande faktorer
Uppsatsen undersöker befolkningsförändring sett ur ett migrationsperspektiv under perioden 2000-2009. Studien visar att 145 av Sveriges 290 kommuner under 2000-talet har minskat i befolkning medan 140 kommuner har ökat i befolkning. Det grundläggande pro-blemet uppsatsen belyser är det faktum att 15 av dessa kommuner minskat i befolkning med mer än 10 procent. Utöver detta tillkommer att 29 kommuner haft en befolkningsökning på mer än 10 procent. Utvecklingen orsakar en skevhet i den kommunala organisationen som medför problem ibland annat den kommunala budgeteringen.
??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.
In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

Goodwill, aktieägarens vän eller fiende? : En kvantitativ studie av hur goodwillpostens storlek pa?verkar fo?retags fo?rma?ga att ge avkastning till aktiea?garna
We investigate if the size of goodwill compared to total assets has any effect on the shareholders return on companies listed on the Swedish Stock market. We put up two different hypotheses with a foundation from previous research and later dismiss one of them. Our evidence does not show any indicators that the size of goodwill have an effect on the shareholders return, which brings us to believe that there, from a share holders point of view, isn?t any need for concern regarding the standards about accounting for goodwill as stated by IFRS. .
