Atopic dermatitis (AD) is a complex, often lifelong allergic disease affecting around 10 % of both dogs and humans. The hallmark symptom is severe pruritus, causing a lowered quality of life. Mast cells (MCs) are known to play an important part of the immunopathogenesis, promoting a faulty T helper cell type 2 (Th-2) response which follows by a production of specific immunoglobulin E (IgE) antibodies towards environmental allergens (Ag). To further investigate the role of MCs and its mediators in the progression of AD, a low-calcemic vitamin D3 analog (MC903) was used to induce AD-like symptoms locally on the ears of two different knock-out (KO) mouse strains. The first strain was Wsh-/- mice deficient in MCs.

Research after a threshold is mentioned and what Sweden does today to improve the radiation protection by laws and regulations. Explaining the atom, what radiation is and how the ionizing radation interacts with the atom. How backscatter affect the picture and the workers and how to protect yourself from backscatter is mentioned. Radiation doses, dosimetry and rules for those who practise radiation is shortly described..

Canine parvovirus is associated with two disorders: enteritis, which is common, and myocarditis, which is rare. Prominent clinical signs of parvovirus enteritis are vomiting, diarrhea and rapid dehydration. Canine parvovirus type 2 (CPV-2) is very contagious. When CPV-2 first emerged it had high rates of mortality, but later studies have shown that most infections are self-limiting and do not require veterinary care. Mortality rates vary greatly, and therefore it is important to determine risk factors for developing severe canine parvovirus enteritis.

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.

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.

This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
