Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Nässvalgsond på hund ? djursjukskötarens område?

The aim was to identify if the veterinary nurse is as competent as the veterinaian in placing a nasoesophageal feeding tube. The aim was also to identify the complications with malnutrition and the advantage and disadvantage of the procedure. This essay is based on several interviews with both veterinary nurses and veterinaries. 16 persons were asked 4 short questions in conjunction with an intensive care/emergency and surgery congress in Gothenburg in February 2013. In addition 4 major hospitals that provided intensive care were asked to answer 5 more detailed questions, one answer from a veterinary and one answer from a veterinary nurse was requested.

Förbättra leveranssäkerhet mot kund : En utredning för att göra tillverkningsprocessen enklare, rakare och stabilare

Det är vanligt att Svenska företag har leveranssäkerhetskrav på sina underleverantörer. Det är normalt att företag får problem att leverera varorna i tid till sina kunder ibland, vilket kan medföra stor ekonomisk förlust för företaget. Denna rapport är resultatet av ett examensarbete vid Mälardalens Högskola som utförts på uppdrag av International Aluminium Casting AB i Eskilstuna.Syftet med denna rapport är att se över IAC:s fabrik i Eskilstuna ute på Vilsta, för att kartlägga deras tillverkningsprocess och identifiera problemområden i tillverkningen som kan ha direkta effekter på leveranssäkerheten.För att uppnå syftet med arbetet utfördes först en litteraturstudie inom området effektiv produktion, följt av en empirisk studie som utfördes i fabriken på företaget. Detta ger arbetet en hög betryggande anknytning om hur verkligheten ser ut och ger innehållet en bekräftelse emot teorin inom området. En noggrann nulägesbeskrivning utfördes för att få en konkret bild över hur tillverkningsprocessen gick till och för att kunna se vart i processen det finns problem, vilket skulle kunna påverka företagets förmåga att leverera sina varor i tid till kunden.

Fjärrlåneverksamheten på Borås och Kalmar högskolebibliotek

The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..

Förskolans matematik : pedagogers arbete med de yngsta förskolebarnen

The study´s main purpose is to examine how three educators who work with children ages 1-3  in three different preschools working with mathematics in preschool. I have used a qualitative research in the form of interviews to obtain educators perspectives on their working. The educator´s stories about their working methods are the most important findings and it turned out that the interviewed educators was working fairly similar in terms of mathematics learning with the youngest children  in preschool. They both schedule mathematics in various activities and work with it in everyday situations. Their different approaches can be divided into five different categories which are: planned theme work and experiences, body and play, interaction and conversation, environment and materials, visualize mathematics..

Kroppens Kultur : Fysisk teater som begrepp, dess diskurs och status på teaterfältet.

This master?s thesis discusses the term physical theatre from a discourse point of view. It also focuses on aspects of power from a field theory perspective. The main theory used is Pierre Bourdieu?s field theory, and I try to apply this onto critical discourse analysis, mainly taken from Michel Foucault.

Risksäkra liv : i skuggan av systemkollaps

The thesis is based on a case study of a Swedish discussion forum where survivalism and prepping is the main focus. The awareness of an abrupt and immanent breakdown together with a full and thorough preparation for any conceivable threat posed by that breakdown is what legitimizes survivalism and prepping. This preparation, or risk-proofing is 1) grounded in an isolation of the body and its predispositions from perceived risks, and 2) actualized through artefacts, theoretical and practical knowledge and awareness. Stories of the embodied survivalist are also stories of masculine and heterosexual subjects and ?the others?.

Klinisk termografi som diagnostiskt hjälpmedel vid rörelsestörning hos häst :

Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner. The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses. Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs. In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.

Aktiv lastbilsstol för bättre förarergonomi och hälsa

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

Forskningscirkeln och dess påverkan på historieundervisning i en mångkulturell miljö

Under två terminer har vi medverkat i en forskningscirkel på en grundskola som behandlat historieundervisning i en mångkulturell miljö. Forskningscirkeln startades i samband med att den aktuella skolan fick ett stort tillskott av elever med invandrarbakgrund. Det ena syftet med detta examensarbete är att synliggöra lärarnas syn på rollfördelningen inom den aktuella forskningscirkeln. Den rollfördelning vi syftar på är framförallt den mellan forskarna och lärarna, inte lärarna emellan. Det andra syftet är att se hur lärarna upplever att de påverkats av att medverka i forskningscirkeln, och då med fokus på historieundervisning i en mångkulturell miljö.

Pojkars läslust : en studie av hur pojkar uppfattar och uttrycker sitt intresse för läsning

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.
