With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Syftet med undersökningen är att genom en jämförande modellstudie ta fram ett eller flera sätt att nedkämpa en motståndare utrustad med tungt reaktivt pansar. Reaktivt pansar har tidigare endast använts för att hindra RSV-strålar att penetrera pansar. Men teknikutvecklingen har nu medfört att dagens reaktiva pansar utöver skydd mot RSV-strålar också klarar av att reducera pilprojektilens förmåga till penetration. Amerikanarna som tidigt upptäckte att Ryssland hade tillgång till tekniken började direkt utveckla ny ammunition för att möta detta. Men vad har vi gjort i Sverige, sen detta uppdagades? Kan vår Stridsvagn 122 fortfarande lösa sin huvuduppgift: att slå ut andra stridsvagnar?I studien gör författaren antagandet att spårljuspansarprojektil 95 inte får genomslag på en stridsvagn utrustad med tungt reaktivt pansar, typ Kontakt-5.

The population of seatrout and salmon are threatened by over-fishing in the sea and loss of spawning and growing habitats caused by logging activities in many swedish rivers. The knowledge of the spawning migration and the habitat use of the seatrouts and salmon are limited. This study analyse the upstream spawning migration of Atlantic salmon and sea-running brown trouts from the lower part of the rivers to their spawning sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of spawning sites in the rivers will help these fish population in future restoration programs. In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20 salmon radio tagged and subsequently released and followed during their spawning migration upstream Vindelälven. They were tracked on their position in the river once a week.

The company Bergteamet, Boliden, Sweden, is installing ventilation shafts of the Garpenberg mine. For such work a platform is needed which you can stand on and work from. The Shaft Reinforcement Team at Bergteamet performs the installation work and is the sponsor of the platform. The project described in this report is performed at the department MEC, Mining Equipment Construction, which has been given the task to design and construct the platform, customized for the current shaft. After this the platform is manufactured and inspected at the workshop at Bergteamet.The design work was carried out as follows:- After an initial meeting a requirement specification was worked out, describing the problem and previous experiences of platforms and requirements for the design and equipment.- A concept sketch was developed with consideration of surrounding factors.- A constructed 3D model was presented along with the choice of materials.

Floating innebär att man ligger i en tank med tempererat saltvatten som gör att man blir tyngdlös och flyter. Floating kan bland annat minska ner stressymptom. Kundens konsumtionsbeteende styrs i hög grad av varumärken. För att stärka ett varumärke måste relationer skapas med hjälp av värdeskapande aktiviteter. Sinnesmarknadsföring är ett sätt att nå ut till kunderna på ett djupare plan och stärka deras relation till varumärket och varumärkets identitet genom att integrera de fem sinnena i marknadsföringen.

Denna undersökning syftade till att undersöka om Larson m.fl. (2012) teori om kantiga och runda former kan appliceras på silhuetter i ett ovanifrånperspektiv, samt om de kan förmedla hotande eller lättsammare intryck för betraktaren. Kan betraktaren uppfatta vilken roll karaktären är ämnad att inneha inom ett MOBA-spel och blir någon av rollerna lättare eller svårare att avläsa när dess geometri förändras? För att ge bakgrund till undersökningen går arbetet igenom tidigare arbeten och undersökningar inom geometriska former, silhuett, analys med ikonografi, strategispel och karaktärsdesign. Som artefakt till undersökningen skapades tre olika karaktärskoncept som behandlar klasserna Carry, Support och Tank.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicin and Clinical NutritionAbstractTitle: Does supplementation of omega-3 during pregnancy affectprevalence of allergy in infants and children?Author: Peter Eliasson, Anna RahmSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 ECTSDate: 2012-04-12BackgroundEpidemiologic research has shown an association between a high intake of fish and allergy.The underlying theory is that allergy develops already at a prenatal stage and food intakeduring pregnancy has been shown to be significant. Conducting research on allergy isproblematic since it has genetic, as well as enviromental, determinants.ObjectiveThis thesis attempts to conclude and evaluate research on a connection betweensupplementation of omega-3 during pregnancy and allergic outcomes in infants and children.Search strategyThe literature search was conducted in the databases PubMed and Scopus. Among thekeywords chosen were omega 3, supplement, pregnancy and allergy.Selection criteriaHuman RCT, that measured allergy, where the intervention consisted of supplementation withomega-3 for at least ten weeks during pregnancy and ceased at birth.Data collection and analysisThree articles were chosen for this thesis. The articles were examined using templates fromSBU and the quality of evidence was evaluated according to GRADE.Main resultsNone of the articles showed a protective effect on allergic outcome but in one of the studiesthere was significant reduction in eggallergy and another showed significant lower occurrenceof severe eczema.ConclusionsSupplementation with omega-3 during pregnancy does not occur to have an protective effecton allergic outcome in infants and childen but the evidence for this is considered to bemoderate.

This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.

Det har funnits problem med utmattningssprickor hos bränsletankarna på stridsfordon 90 och de beräkningar som gjorts har inte kunnat förutspå skadorna som uppkommit. Därför hade ett intresse uppkommit för att se hur vätskan påverkar strukturen vid vibrationer. Detta examensarbete har genom experiment försökt skapa en idé om hur strukturen hos en behållare påverkas vid vibrationer när vätska fylls på inuti behållaren. För att få klarhet i detta designades först ett testobjekt i I-deas för att få fram ett antal önskade modformer. Efter tillverkning utfördes prov i provavdelningens vibrationsbänk med olika vätskenivåer.

A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.

I takt med stigande oljepriser har ett av Sveriges största odlingsföretag Svegro bestämt sig för att byta ut sitt nuvarande värmesystem. Svegro består idag av växthus på ca 50 000 m2 på Thorslunda gård, Färingsö.Uppvärmningen sker idag med hjälp av oljeeldning samt den värmeenergi som omvandlas från växthuslampor. Det nya värmesystemet kommer att använda sig av ett annat förbränningsalternativ än mineralolja. Detta kommer göra det möjligt för Svegro att sänka sina energikostnader och minska miljöpåverkan genom reducerat koldioxidutsläpp. Kraven som ställs är att det nya värmesystemet ska kunna integreras med det befintliga värmesystemet och samtidigt leva upp till dagens ekologiska krav.
