Detta examensarbete är resultatet av en utredning av produktionsbegränsningar och produktutveckling på Volvo Construction Equipment AB Component Division i Eskilstuna. Produktionssystemet på Volvo CE genomgår en stor förändring då det går från att fungera som en funktionell verkstad till att bli flödesinriktat. Detta gör att helt nya krav ställs på produkternas konstruktion och utformning. Det är nu inte möjligt att anpassa maskinerna eller operationsföljderna efter artikeln i samma utsträckning som tidigare, man kommer att vara tvungen att anpassa artiklarna efter produktionslinan. Därav har en litteraturstudie inom Concurrent Engineering gjorts som belyser hur man bör jobba som organisation och vilka verktyg man har till sitt förfogande, för att utveckla produktionsvänliga produkter.

Komponentavskrivning blev aktuellt i samband med att EU valde att följa de standarder som IASB utfärdade. Efter införandet av K3-regelverk för svenska företag kom det att bli ännu mer aktuellt med komponentavskrivning i Sverige.Då tidigare forskning har riktat kritik mot komponentavskrivning, fann vi det intressant att undersöka vilka svårigheter som kan finnas med komponentavskrivning i ett petrokemiskt företag utifrån två olika perspektiv. Med detta som grund valde vi att undersöka vilka svårigheter som fanns utifrån ett redovisningsperspektiv och ett operativt perspektiv samt att undersöka hur interaktionen går till mellan dessa två perspektiv.Den teoretiska referensramen i arbetet innefattar svensk praxis, IAS 16, K3-regelverk, komponentavskrivning, kritik mot komponentavskrivning, redovisningsfunktionen och operativa verksamheten. Empirin utgörs av intervjuer som är utförda hos det petrokemiska företaget Borealis där vi har undersökt vilka svårigheter som finns med komponentavskrivning i redovisningsfunktionen samt den operativa verksamheten. Vi har även undersökt hur interaktionen gällande komponentavskrivning ser ut mellan redovisningsfunktionen och den operativa verksamheten.

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.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Aim: The aim of the study is to show how a Bildung-oriented biology teaching could be designed, along with providing classroom examples of such teaching. In this study, the term Bildung, is defined based on the German Didaktik tradition as competences for self-determination, constructive participation in society, and solidarity. Theory: The study is based om Englund?s thoughts of teaching as didactic choices that express different views of meaning, socialisation, method, and context. This is referred to as companion meanings. Additionally, the theoretical framework is influenced by Gadamer?s thoughts on understanding through dialogue and Klafki?s didactic analysis of educational content for Bildung-orientated approaches. Method: The empirical qualitative study is based on ten semi-structured interviews of biology teachers at Swedish Folkh?gskola.

Makt samt organisatoriskt commitment är två väsentliga begrepp gällande ett företags ledarskap och deras anställda. Ledarskapets kärna utgörs av den influens ledargestalten har över sina underordnade och begreppet makt ska för ledaren fungera som ett drivmedel gällande hens influens. Det gäller således för ledargestalter att tillämpa makten i syfte att influera sina anställda mot organisationens uppsatta mål. För att lyckas få de anställda att sträva efter samma mål som organisationen satt upp samtidigt som de ska arbeta för att få kompetent arbetskraft att stanna krävs det av ledaren att hen kan främja organisatoriskt commitment bland de anställda. Syftet med studien är därmed att utifrån positioneringsmakt och kunskapsmakt analysera hur ledare för ett konsultföretag skapar affektivt, kalkylerande och eller normativt commitment hos sina anställda.Då studien avser att inge en djup och grundlig förståelse gällande dess syfte tillämpas en fallstudiedesign med en kvalitativ forskningsstrategi samt en deduktiv ansats.

Bull terrier hereditary nephritis is caused by a mutation that leads to an inadequate synthesis of collagen type IV, which is an important component in the basement membranes. The inheritance of the mutation is autosomal dominant in bull terriers and progression to renal failure takes variable time, from several months to ten years. Proteinuria is the first clinical sign of the disease and the diagnosis is confirmed by transmission electron microscopy of renal tissue where typical ultrastructural changes in the glomerular basement membrane (GBM), thickening and multilaminar splitting are found. This study was performed in order to find out the occurrence of hereditary nephritis in bull terriers in Sweden through examination of urine samples and renal tissue and comparisons with how the disease is described in the literature. Urine samples from 76 Swedish bull terriers were collected and examined for proteinuria.

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

The digitization of patient data and medical records used by the healthcare-industry in Sweden is rapidly developing. However; developing and changing things in this field is not an easy task because of the circumstances surrounding it. Digital systems intended to process, and hold, sensitive personal data, such as medical journals, must be developed with laws, confidentiality, integrity and availability in mind to secure that none of this data gets compromised.A complicating factor in regards to this is the fast rate of development within IT in contrast to the much slower bureaucratic process of the justice system. This means that laws and regulations oftentimes aren?t up to date with the newest available technology.With the purpose of establishing set regulations on how patient data should be properly handled the Swedish government enacted the Patient Data Act (sv.

Malassezia otitis in dogs is a common cause of visit to a veterinary service. In otitis externa due to Malassezia overgrowth the dog has a higher number of yeast organisms and/or a local inflammatory response to the micro organism. Common clinical signs include pruritus, erythema, swelling and increased exudate production. Clinical symptoms and results from cytology of ear swabs from the ear canal is the mainstay for diagnosis. Any underlying condition has to be identified and corrected to avoid relapse. The treatment options for infective otitis externa are based upon topical administration of eardrops containing antibiotics, steroids and antifungals.
