Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Inom Försvarsmakten används motordrivna generatorer för att förse många förbandsenheter med elektricitet. Dagens bullriga och vibrerande elverk är idag möjliga att ersätta med tystare bränsleceller. På köpet erhålls en bättre ergonomi för alla som arbetar i hytter som strömförsörjs av elverk. I rapporten redovisas funktionen för olika typer av bränsleceller, vilka bränslen de använder sig av och hur dessa kan transporteras. Dessutom redovisas hur två elverk används och vilka förbättringar som kan åstadkommas vid byte till bränsleceller.

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.

Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells.Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgV?) of MALT lymphomas.Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis.Successful amplification was seen in 10/13 cases and sequences of IgV? genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the V?3 family, 2 from V?1 and 1 from the V? 4 family..

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

Denna rapport bygger på den kommande solcellsfasaden på kvarteret Frodeparken i centrala Uppsala. Projektet genomförs genom ett partneringavtal mellan Skanska Sverige AB och Uppsalahem. Syftet med detta examensarbete var att skapa en underhållsplan samt en investeringskalkyl för projektet. En teknisk bakgrund för solcellsanläggningar har sammanställts för att förstå hur systemet fungerar. Underhållsplanen grundas på fakta från solcellsleverantören och uppgifter från referensobjekt. Det har visat sig att solcellsanläggningar kräver väldigt lite underhåll. För att få en bred syn på investeringen har ett antal simuleringar på investeringskalkylen genomförts.

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

Denna rapport kommer att redogöra för NK-cellers (Naturliga mördarceller) beteende vid odopat tillstånd. Det vi kallar dopning är när NK-celler aktiveras genom interleukin-2, detta är en signalerande molekyl i vårt immunsystem som reglerar aktiviteten hos vita blodkroppar vilka utgör en del av immunförsvaret.Med hjälp av ett par mikroskopfilmer har vi kunnat följa varje enskild NK-cells migration(rörelse) och interaktion med våra målceller i ett prov under en 8-timmars period. De målceller vi använder är en sorts tumörceller, HEK 293T(Human embryonic kidney 293T cells. Vi har valt att spåra cellerna manuellt med ett program kallat ImageJ och automatiskt med ett matlabprogram, Baxter algorithm. Anledningen till att vi dessutom valt att spåra automatiskt är för att kunna avgöra hur väl detta program kan spåra celler.

This report is a thesis on requests from Sandvik Mining and Construction (SMC) in autumn of 2012. The goal of this work was to study the feasibility of creating and implementing an Equalized preventive maintenance program in SMC maintenance operations and reduce downtime for preventive maintenance (PM). To investigate whether this was possible, the authors studied the current procedures for the PM. The authors have collected and analyzed all relevant information within the maintenance department reporting system as well as through interviews determined whether it is practical to introduce a Equalized PM programs. The authors had also studied the possibilities to entrust part of the maintenance work to the operators of the machine cells.

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Atopisk dermatit hos hund (CAD) är en kliande hudsjukdom med komplex patogenes som involverar felreglering av immunförsvaret, allergisk sensibilisering, defekter i hudbarriären, mikrobiell kolonisation samt olika miljöfaktorer. Dock är den inbördes relationen mellan dessa faktorer inte klargjord. En ökad förståelse för sjukdomens patogenes, bland annat den immunologiska bakgrunden inklusive vilken T-cells- och cytokinprofil som kännetecknar sjukdomen, skulle kunna öka drabbade hundars livskvalitet genom förbättrade behandlingsmetoder. Studier har undersökt cellinfiltrat och visat att både CD4+ och CD8+ T-celler förekommer i ökade mängder i huden hos AD-hundar, och således att det finns Th-celler samt CTLs och/eller suppressoriska T-celler i denna hud. Dessa studier hittade också förhöjda CD4/CD8-kvoter, vilket visar på en ökad lymfocytreaktivitet.
