Tankinsats för dieselbilar : Från idé till prototyp
This thesis describes the development of a tank insert for diesel cars, from idea to a prototype. The idea is to design an insert which makes it impossible to refuel petrol in a diesel car. The insert shall be installed in the existing tank opening on diesel cars. The tank insert is designed for the Swedish company SverigeGrepen AB located in Vänge, just outside Uppsala. Their main product is a pitchfork that is ergonomically designed and durable.A pre-study were performed in which information relating to fuel caps, tank openings, petrol- and diesel nozzles were collected.
Variation in frequency of alleles in the MTNR1A gene with possible impact on ability of ewes to show oestrus out of season
In Swedish sheep industry it is desired to have lambs slaughtered evenly distributed over the year. Swedish sheep are generally seasonal breeders with lambs born in the spring and slaughtered in the autumn. Some of the breeds, e.g. Swedish Finewool and Roslag sheep breeds have shown ability to lamb out of season. For increased knowledge on the possibilities to breed for out-of-season lambing in Swedish sheep breeds, the aim of this master thesis is to study the variation in frequency of two alleles in the MTNR1A gene in the three breeds; Gotland, Swedish Finewool, and Roslag sheep.
Effekter av CI-terapi för barn med cerebral pares: En litteraturstudie
Bakgrund: Cerebral pares är en skada som uppkommer i den outvecklade hjärnan och drabbar ca 250 barn per år i Sverige. Skadorna leder till begränsningar av aktivitetsförmåga. En behandlingsmetod för barn med cerebral pares är constraint-induced therapy (CI-terapi) som innebär intensiv, uppgiftsspecifik och repetitiv träning av övre extremitet, där den icke drabbade armen hindras att användas. Genom behandlingen påminns kroppen att använda den drabbade armen och nya rörelsemönster utvecklas. Syftet: Syftet med studien var att, med ICF som modell, granska publicerade vetenskapliga artiklar för att undersöka om CI-terapi kan förbättra aktivitetsförmågan hos barn med cerebral pares.
Kunskapens konstellationer: om ämnesanalys och tvärvetenskaplighet
The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter
Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.
Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage
When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.
Made by China : Outsourcing av Konstruktionsarbete till Kina
Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things mounts and stands for flat screens and projectors.
På seglats i själens djup - en studie av droginducerade mystika tillstånd och erfarenheter
The use of hallucinogenic plants has throughout human history been used for religiouspurposes, in order to induce mystical states of mind, often interpreted as meeting with godsand spirits. In recent years, this practice has been taken up by people interested in theexploration of their psyche and spiritual side. This group of people, referred to as?psychonauts?, communicate with each other through internet based forum, where theyshare their experiences in so called ?trip reports?. The aim of this study was to see whatrole psychedelic drugs can play when used in a spiritual/religious context, and whetherthese sorts of mystical states of mind could tell us about more traditional mysticalexperiences.
Utredning av Valboåsens grundvattenmagasins förbindelse med Gavleån : En analys av halten löst syre genom mätningar
Gävle kommuns VA-huvudman Gästrike Vatten AB ansvarar för dricksvattenproduktionen i Gävle. För Gävles tätort tas vatten från Valboåsen som sträcker sig från öster om staden, genom staden och vidare norrut. Denna rapports syfte är att genom mätning av halten löst syre undersöka Valboåsens förbindelse till Gavleån. Detta kommer ge en ökad förståelse för åsens komplexitet. Resultatet kommer också att användas för att verifiera och utveckla den konceptuella modellen över flödena i åsens grundvattenmagasin som tagits fram av Midvatten AB.
System, stabilitet och makt - informationsdiskursen i Organizing Knowledge
TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.
Glukokortikoiders inverkan på fertiliteten hos ston med kvarstående betäckningsinducerad endometrit
Kvarstående endometrit efter betäckning eller insemination, "perstistant mating-induced endometritis" (PMIE) har länge orsakat problem med fertiliteten hos ston och anses i vissa fall vara den största anledningen till infertilitet. Ett av de tydligaste tecknen på att ett sto drabbats av PMIE är att det finns ?2cm vätska i livmodern 6-24 timmar efter betäckning/insemination. Det inte har funnits några standardiserade behandlingsprotokoll för PMIE men nya studier har visat en markant ökning i dräktighetsfrekvensen när ston som identifierats som predisponerade för PMIE har behandlats med glukokortikoider innan betäckning/insemination. När ston med antingen tidigare oförklarad infertilitet eller tidigare symtom på PMIE behandlats med prednisolon innan insemination har dräktighetsprocenten ökat från 3% till 65% dräktighet samt från 0% till 64,5% dräktighet.
Vaccinationsbiverkningar hos hundar i Sverige
Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.
Den interaktiva IR-forskningens genomslag i söktjänsterna på webben
The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.
Hundens parvovirus : patologi och riskfaktorer
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.
