This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

Bakgrund: Hälsofördelarna med amning är välkända, och sedan 1992 försöker svenska sjukhus arbeta efter internationella amningsrekommendationer. Trots detta framkommer brister i vården och amningsstatistiken i Sverige sjunker.Syfte: Syftet med denna studie var att undersöka amningsdurationen hos förstföderskor, om den kunde associeras med vården de fått i samband med barnets födelse och första levnadsdygn, samt med mammornas skattning av amningsstöd vid amningsstart.Metod: Designen var en longitudinell kvantitativ tvärsnittsstudie och urvalet var icke slumpmässigt konsekutivt. I samband med utskrivning från BB, tillfrågades 63 mammor om att delta i en enkätstudie med frågor gällande vården de fått i relation till amning och 52 mammor besvarade enkäten. Efter nio till tolv månader blev de uppringda för en kortare uppföljning och 50 mammor valde att delta.Resultat: Medianen för durationen av exklusiv amning var tre månader och tre veckor och medianen för durationen av partiell amning var åtta månader. Amningsstödet på BB skattades högre vid det första mättillfället, men det påvisades inte ha något samband med amningsdurationen.

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.

The purpose of this study is to present populism as a political phenomenon and to impose focus on the rightwing populist parties that are active in Scandinavia. This essay begins with a presentation of the three rightwing political parties in Scandinavia. The rightwing populist parties have successfully developed their rhetoric and effectively influenced the political establishment in Sweden, Norway and Denmark. The parties that the essay focuses on are theSwedish democrats (SD), the Norwegian Progress party (FRP) and the Danish People`s party (DF). These parties are interesting in the sense that they share many opinions and are active in comparable political atmospheres, but also that they use approximately the same rightwing populist rhetoric as a way of exerting leverage on political policy.The theoretical segment is constructed on a descriptive historical background of populisms three different phases.

SUMMARYThis work consists of a review of the medical records of 142 horses that visited the Equine dermatology clinic, at the University Animal Hospital, UDS, at Ultuna, Uppsala, Sweden, between January 2007 and June 2010. The study answers certain main questions like clinical signs responsible for the visit, the most common diagnoses, their diagnostic procedures, treatment modalities and finally, the outcome of treatment.Among 50 diagnoses, four were predominant followed by additional 46 diagnoses, each presenting by few or, in many cases, only one horse. The most common dermatological problem diagnosed was Equine Sarcoid representing 18,3 % of the cases (26/142), which probably reflects the initiation of a Sarcoid treatment-trial in 2007, that resulted in an accumulation of sarcoid horses in the clinic .The second most common diagnosis was Atopy 12 % (17/142) followed by Allergy with skin affection 9,2 % (13/142) and Acute superficial pyodermia 4,9 % (7/142). If the horses were divided into diagnostic groups, the majority (34,5 %) belonged to HA5 group, (Immunological skin diseases), followed by group HA4, (Infectious and inflammatory conditions of the skin) (22,5 %) and HA6, (Neoplasia) (21,8 %). Traumatic skin injuries represented only 2,1 % of the cases, compared to 80 % of horses in the Agria insurance statistics for veterinary care.The most common clinical sign and reasons for veterinary consultation was pruritus (35,9 %), suspected sarcoids (17,6 %), alopecia (12,7 %), nodules (12 %), seborrea, scaling and crusts (9,2 %) and excoriations (5,6 %), respectively, followed by a scattered number of more uncommon symtoms.The diagnostic methods most frequently applied were cytology and biopsy, used in 41,5 % and 36,6 % of the cases, respectively.

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

I Sverige finns det idag ett stort antal dammar och nära hälften av Sveriges elproduktion kommer ifrån vattenkraft. Höga säkerhetskrav ställs på dammarna då konsekvenserna av ett dammbrott kan orsaka stor ekonomisk skada både i form av minskad produktion och som uppbyggnadskostnader. Dammbrott kan även utgöra risk för skador på människor och omkringliggande miljö samt byggnader.Det finns flera dimensioneringsmetoder för att uppfylla gällande säkerhetskrav på konstruktioner. De tillämpningsvägledningar som används vid stabilitetsanalys av betongdammar baseras på gamla deterministiska metoder med säkerhetsfaktorer. Det arbetas med att ta fram nya tillämpningsvägledningar baserat på sannolikhetsbaserade metoder.

Stress påverkar immunförsvaret och den fysiska hälsan samt individens välfärd och dess psykologiska hälsa men verkningsmekanismerna är fortfarande relativt outforskade. Det finns indikationer på att djur med lägre välfärd är mer stressade och därmed känsligare för infektion samt har svårare att göra sig av med infekterande agens än djur med högre välfärd. Målet med denna studie var att undersöka om det finns ett samband mellan välfärdsfaktorer och utsöndring av patogenen Cryptosporidium spp. hos unga kalvar. Utöver detta avsågs att skapa en modell där parametrar från välfärdsbedömning används för att förutse utsöndring vilket i framtiden kunna ge en mer riktad provtagning i besättningar där smitta misstänks. Sextiofem kalvar, mellan en och åtta veckor gamla, från två svenska besättningar undersöktes och bedömdes i studien.

Erasteel Kloster AB Söderfors have been commissioned by the county administrative board in Uppsala län to make an inventory of possible contaminations in theirs industrial- and landfill areas on the basis of the Swedish Environmental Protection Agency?s; ?Method of Surveying Contaminated Sites-phase 1? (MIFO-fas 1). The inventory starts with maps and archive studies, place visits and interviews, and finally a risk classification is done. A risk classification is a compilation of four categories; pollutant toxicity, contamination level, possible spreading condition of the pollutant, sensitivity and protection value of the environment. In this paper five partial areas (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin, Östra verken and Myrområdet) have been described from a historical point of view. Only parts of four areas have been risk classified (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin and Östra verken), due to that the other areas isn?t own by Erasteel Kloster AB. Holmen- and Jörsöområdet Holmen- and Jörsöområdet have during the entire activity time been carried out as the production core in the company.

Att rida ut i naturen på sin häst är ett sätt att uppleva landskapet men det är också motion och rekreation. Målet med uppsatsen är att studera och beskriva det nuvarande intresset och arbetet på lokal, och även till viss del regional nivå, med att förbättra tillgängligheten för ryttare i utvalda delar av Skåne som består av intensivt brukad jordbruksmark. I de utvalda områdena finns det en problematik med ett ökat antal ryttare och hästar och få möjligheter att röra sig i landskapet. Uppsatsen undersöker hur tre kommuners processer, med tyngdpunkt på Ängelholms kommun, ser ut för att öka tillgängligheten för ryttare. Genom intervjuer med personer som är aktiva i ett ridslingeprojekt i Ängelholms kommun och erfarenheter från de andra kommunernas representanter skapas en bild av hur arbetet ser ut.

The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.
