The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Syftet med examensarbetet har varit att studera hur trafiken i Jönköping ser ut och ta fram åtgärdsförslag till de trängselproblem som finns. Syftet har även varit att studera hur framtida trafikflödesförändringar och framtagna lösningar kommer att påverka dagens vägnät i centrala Jönköping.Rapporten är indelad i fyra större huvuddelar. Dessa huvuddelar är en bakgrundsstudie, litteraturstudie, simuleringsstudie och åtgärdsförslag.Bakgrundsstudien visar hur Jönköping är uppbyggt, var trafikgenererande områden är belägna samt hur infrastrukturen ser ut. Även framtida förändringar i området kring det planerade simuleringsarbetet har studerats och analyserats.Litteraturstudien ger en inblick i hur trafikproblem angrips, hur fyrstegsprincipen tillämpas, vilka åtgärder som kan användas för att reducera trafiken samt hur OD-matriser kan tas fram. Även kunskaper om simulering, hur simuleringsarbeten utförs och om programvaran AIMSUN kan hämtas i litteraturstudien.I simuleringsstudien har en modell skapats i AIMSUN och indata samlats in, bearbetats samt matats in i AIMSUN.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Piezoelektriska material används flitigt i olika sensorer då de kan generera en mätbar elektrisk signal vid tryck eller töjning. Arbetet utreder hur ett piezoelektriskt garn innehållandes Polyvinyldiflourid (PVDF) påverkas av faktorer som långvarig mekanisk deformation, fukt och värme. Fokus har legat på det piezoelektriska garnets egenskaper men projektet undersöker också hur integrering i tyg samt applicering i en textil produkt fungerar. Det piezoelektriska garnet har utsatts för ett stort antal tester. I de flesta tester har proverna utvärderats genom cyklisk deformation i en extensometer.

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.

Med hjälp av denna studie ska det klargöras vilka effekter butiksaktivteter kan ha på försäljningen i butiker inom livsmedelsbranscher. Vi har utformat två olika exponeringar i två ICA nära butiker. Exponeringarna har baserats på AIDAS-modellen i stor utsträckning samtidigt som vi studerade relevant teori om marknadsföring i butik har vi utformat våra exponeringar. Vi har tittat närmre på hur sinnesmarknadsföring kan påverka vid dessa aktiviteter. Butiksaktiviteterna har varit en tyst och en högljud exponering av maträtten "Korv Stroganoff".

Persistent pink in beef patties and hamburgers is a problem in the meat industry that has been known for a few decades. It is a costly problem as it can give rejections of food by consumers. Studies around the world have tried to solve the problem but it still remains a mystery. There are many different theories of what is causing the red colour. Some of the most likly theories are reducing hemocromes, high microbiological loads, contamination of nitrite or organic/non organic substanses, DFD meat etc.

I have studied the suburban municipality of Botkyrka, south of Stockholm, from a rural perspective. Through that I`ve compared how countryside comes into being with the planning and building of suburbs. I have looked for a definition of Countryside, and found that it is often explained or defined in negative terms, as what it is not. In that it says nothing about what it really is, or about the qualitiies it has to it. Botkyrka is a suburb, but it does in large parts consist of countryside. Apart from defining countryside and rural I´ve been searching for a definition of suburbia, of it´s structure and the mental picture we have of it as a cultural phenomena. In order to understand the role that suburbs have in planning I describe their history from Italian renaissance villas to sprawl. By opposing urban and rural, modern urban planning and how rural areas are created, I´ve come to a definition of rural planning and the making of countryside. To make countryside, planning and building should come from individual needs and desires. A relationship to the surroundings based on continous interaction between the human beeing and it´s environment, a constant process of shaping and reshaping. To put my thoughts to the ground I have collected examples of projects and ideas, that fits into my view of what rural planning and making countryside is all about. They are put in different categories according to the possibilities of influence and to what degree it is put into private hands. The first category is ?allemansrätten?, every mans right. That is the rigt to use private land as long as you don´t disturb or destroy.

Tillverkning mot kundorder kräver oftast att hålla ett förrådslager med råmaterial. Ökade kundkrav på korta leveranstider kräver att material skall finnas tillgängligt i lager. Detta ger upphov till ökade lager hos ett företag som i sin tur gör att de binder mer kapital och samtidigt leder till en sämre av­kastning. För att undvika att hålla för stora förrådslager men samtidigt hålla en god servicenivå krävs en effektiv lagerstyrning.Syftet med detta projekt är att ta reda på hur efterfrågan ser ut hos företaget i dagsläget samt kunna ta fram en lämplig prognosmetod och beräkningsmodell mot en viss takt för lagerstyrningen. Prognos­metoderna skall vara ett underlag för inköp vid beställning av material.

The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.

LevMacinstrumentet är ett analysinstrument under utveckling som utnyttjar leviterade droppar på 100 nl ? 2 ?l. Genom att använda leviterade droppar med den omgivande atmosfären som enda kontaktyta, undviker LevMac?en de vanligaste problemen associerade med miniatyrisering av analytiska tekniker, t.ex. kontaminering av provet genom desorption från provbehållaren eller andra gränsytor, adsorption av analyten till omgivningen med minskat utbyte som följd, och optisk interferens vid väggarna av provbehållaren vilket resulterar i störningar av detektionen.Tillsatser till den leviterade droppen kan göras i pl-området och reaktioner i droppen kan följas med olika spektroskopiska tekniker.

Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.
