Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

Self-archiving as a way to provide open access to research publications is gaining ground in the area of scholarly publishing. An increasing number of research funders and universities are mandating open access for output associated with their research, which calls for evaluation of the effects of the phenomenon.This two years master?s thesis aims to investigate researchers? experiences of self-archiving. A qualitative web survey was conducted and answered by 41 researchers from several different countries, and a vast majority of the respondents concur with the principle of open access. Although self-archiving shows not to be a guarantee of increased impact for the single researcher, the study shows that might be the case.

Totally 84 differentially expressed mRNA clones from infective L3 larvae of the parasite Haemonchus contortus, a blood sucking nematode, were analyzed with single strand hybridization assay (SSH). Altogether 79 clones were sequenced, edited, and compared with proteins found via BLAST in GeneBank. The aim was to investigate gene expression and potential protein expression following storage at 5 °C for 32 weeks. mRNA was extracted from fresh and stored L3. The SSH derived products were cloned into E.

This Bachelor Thesis is entitled ?Swedish parental leave and gender equality. Effects on women?s conditions on the labour market?. Through our empirical results in conjunction with economical and sociological theories, this Bachelor Thesis attempts to answer the questions: 1) Why are the claims for Swedish parental leave unevenly distributed between men and women? 2) Does the uneven distribution result in discrimination of women on the labour market? 3) How do different designs of parental leave scheme influence women?s conditions on the labour market and which possibilities are there to change these conditions through changes in the design? We make use of case studies from Denmark, Iceland and Great Britain, which work as basis for policy implications for the Swedish parental leave scheme.

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.

This paper discusses the issue of trade dress imitation in the grocery sector. Our study has its starting point in the conflict that may arise between a brand owner and an imitator following an imitator?s marketing actions. In this study we look at the Market Court?s precedents in which this question has been addressed.

This bachelor?s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.

The last few years a lot of media air time has been devoted to training, sports, health and weightloss on a more personal level then before. The new media arena is beeing used at its´ maximumto broadcast wievs on how we should eat, look, exercise and live. This thesis is trying to makebetter understanding on what people in general think is important when it comes to physicaltraining and motivation with the aid of digital media and IT systems. The thesis describes aworkshop that was conducted within the frames of Participatory Design and the outcome of thatworkshop. The workshop was conducted with a group of lead users (in this case instructors at avery large fitness center in Umeå, Sweden) and the main question was ?How can IT be used toachive a positive effect on physical exercise if motivation is the focus??.

This is a bachelor thesis that studies and discuss the question: How can we develop our individual narrative technique with sound design in a Swedish drama production? We have done research and empirical studies. We have analyzed movies to get an idea how we use the sound design in Swedish drama productions today. We have produced a movie that gives sound the biggest part. Key words: Swedish drama production, narrative technique, sound design .

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

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.
