The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

From autumn 2008 Sweden has reinstalled the Special Education Needs teacher education. For future special education teachers and active teachers in the field, it is important to know the history and be aware of future visions to create a good role for the Special Education Needs teachers. This study examines attitudes towards special education and Special Education Needs teachers amongst school principals and classroom teachers at seven schools in Umeå municipality. School principals were interviewed, and a survey was handed out amongst the selected General Education teachers. From this it appears that school principals have a picture of special needs education and Special Education Needs teachers' work that corresponds well with the objectives of the school's governing documents.

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

In 2008 USA was the one country that had the most people behind bars, both in numbers andpercentage, 2,3 million people. Of all the male convicts that were being held in custody aroundthe country's different detention facilities, thousands of them were being exposed to sexualabuse, such as rape. This essay will try to understand why there hasn?t been a bigger public outcryin the American community concerning this. It does so by studying the view of rape as a crime ofgender, by examining religion in USA and the Christian view on homosexuality, looking into thepublics thoughts on prisons and the penalty's purpose plus studying theory's of the publics viewon the prisoner.

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.

Syftet för det här examensarbetet var att praktiskt reducera ställtiden på enbefintlig produktionslinje på Ruukki i Halmstad. Vid tiden då författarna togkontakt med företaget var den nuvarande ställtiden alldeles för lång och långtifrån optimal. I samband med projektets start gjordes det ett antal avgränsningaranpassat till den tiden som fanns tillgänglig.Tillvägagångssättet och metodiken till lösningen bakom ställtidsproblematikenföljer Shigeo Shingos Single Minute Exchange of Die (SMED), där har författarnautfört analyser i form av iakttagelser och tidtagning. Upptäckterna som gjordesunder analys samt implementering var att även om SMED är en direkt metodik förställtidsreduktion finns det andra faktorer som kan motverka implementeringensamt dess goda resultat. Dessa faktorer som påvisades under projektets gång varbland annat de mänskliga aspekterna och den bakomliggande företagskulturen iorganisationen.

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

The intention with the study is to describe the home and life conditions for boys at the age range between 13 to 18 year, who has been under custody according to the § 2 LVU.The empiric is 21 real court cases, judged in Stockholm and to Stockholm counted surround-ings 2006, in which the range of the boys were representative.A text analyze method is used to execute the study. The study penetrates the life situation of the caregiver and how their situation affects the boy and the boys actions.The total conclusion of the study, based on an ecological evolution perspective, is that life-situation of the caregiver affects the boys and the boys actions.The boys are affected negatively by the situation of their caregivers, and according to the study, the boys have established own problems, like difficulties in school, criminality, or other psychological diagnoses. They are also often exposed to physical or psychological violence by the caregiver. Additionally the conclusion is that the caregiver neglect the boys in many other ways, prior themselves and their needs before the boys..

Första linjens ledares roll har under de senaste åren blivit mer ansvarskrävande. Vad är då viktigt för ledare i denna position då det kommer till att åstadkomma förändring? Finns det några utmaningar första linjens ledare stöter på? Denna studie syftar till att belysa första linjens ledares upplevelse av att leda en förändringsprocess. Två frågeställningar skapades; ?Vad anser första linjens ledare som viktigt i sitt ledarskap för att kunna åstadkomma förändring?? samt ?Vilka utmaningar möter första linjens ledare i en förändringsprocess??.

This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability.It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed.

Improved profitability, a reasonable yearly income or the possibility to have employees are all incentives for expansion. A prerequisite for farm businesses to expand is for land to be made available, either to buy or to rent. In Sweden, 43 % of the total arable land is leasehold land, which implies that a functioning leasehold market is of great importance for the Swedish agriculture. Several factors can affect the supply of leasehold land, for instance the leasehold legislation and the Single Payment Scheme. The fact that the leasehold legislation is compulsory, in protection of the leaseholder, might keep land owners from leasing their land out.
