Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..

För att kunna prestera bra under fysiskt krävande ishockeymatcher krävs det att spelarna harhög maximal benstyrka och en hög explosiv förmåga. Bilaterala knäböj är en erkänd och välspridd övning för att förbättra power och muskelstyrka i benen. Unilaterala knäböj är än mersportspecifika för ishockeyn. Vid en isokinetisk rörelse är hastigheten förutbestämd ochdärmed konstant medan kraften kan förändras under rörelsen. De flesta isokinetiska systemhar varit designade för unilaterala isolerade övningar, men gällande isokinetiskaflerledsövningar så som knäböj tycks det inte finnas någon forskning om i nuläget.Studiens syfte var att undersöka effekten av sex veckors unilateral styrketräning (knäböj),antingen genom traditionell eller genom isokinetisk träning, på power i unilaterala ochbilaterala jump squats och 17.3 m sprinttid på is hos manliga juniorishockeyspelare.20 manliga ishockeyspelare på elitnivå, 18-19 år gamla, delades slumpmässigt in i två olikaträningsgrupper.

Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

In modern dairy production, the newborn calf generally is separated from its mother and put in a single pen for some time before it is introduced to group housing. Group housing is becoming more and more common because it saves the farmer a lot of valuable time. Even thought group housing has a lot of benefits it is often associated with a higher morbidity and mortality in the young calves. Therefore, knowing the optimal way to use the group pen lies in many farmers? interests and the importance of different factors such as the optimal age of introduction is important to evaluate. The aim of this study was to investigate the effect of age at introduction to group housing on the health of the calves in the group pen.

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can exclusive enteral nutrition replace steroid treatment in pediatric Morbus Crohn?Author: Hanna Rymark Lehnér and Josephine PetterssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012Background: Morbus Crohn is a chronic inflammatory bowel disease which periodically causes great suffering for the patient. There is solid scientific evidence that treatment with steroids effectively induces and preserves remission. However, side effects are many and a great risk for stunted growth and skeletal development exists in children. A widespread view is that exclusive enteral nutrition is as effective as steroids in pediatric Crohn´s.

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

A possible treatment for patients with lymphoma and myeloma is stem cell transplantation (SCT). SCT is preceded with cytostatic treatment. There are several side effects related to this treatment, for example fatigue, nausea, constipation/diarrhoea, pain, mucositis and loss of appetite. Aim: Investigate which side effects related to the treatment where most troubling after SCT and if nurse assessment and patient assessment differ. Methods: A quantitative empirical study with repeated measuring.

Svensk doktrin framhåller sex grundläggande förmågor för analys av motståndaren. Dessa är ledning, uthållighet, und/info, rörlighet, verkan och skydd.Förmågorna är en tankemodell avsedd för att nå maximal effekt i sitt agerande. De är ständigt närvarande på stridsfältet, de påverkas av varandra och deras betydelse varierar över tid. Syftet med uppsatsen är att belysa IRA utveckling mellan 1968-1974 utifrån de sex grundläggande förmågorna.Resultatet visar att IRA utveckling under tiden för studien främst skedde inom förmågan verkan, andra förmågor som ledning och und/info tog längre tid att utveckla. En orsak till detta kan vara att studien omfattar inledningen av konflikten och IRA utveckling mot att bli en icke-statlig väpnad aktör..

Sweden's government is dedicated to the goal of having a vehicle fleet that is independent of fossil fuels by 2030. Achieving these goals requires, among other things, new types of fuel that give lower net emissions of carbon dioxide. The present market includes stations offering lowlevel blends of renewable fuels in conventional diesel as well as some stations offering renewable fuels only. The purpose of this study is to survey purchasers? attitudes to the use renewable fuels in roundwood and bioenergy transport in forest- and energy companies. The study was based on qualitative interviews through a combination of face-to-face meetings and telephone interviews with each sample group. The total number of respondents was ten (10), consisting of five (5) from forest companies and five (5) from energy companies. Transport service purchasers were generally positive to renewable fuels and considered these necessary in the future.
