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 debate about questions concerning corporate governance has intensified in Sweden the last decade. From July 1th 2008, the Swedish Code for Corporate Governance was extended to comprise all Swedish companies listed on the OMX Nordic Exchange Stockholm. Our aim with this master thesis is to examine the effect of the Revised Code on Swedish corporate governance and in particular its contribution to creating value or costs. We do this through a qualitative study of 22 interviews with representatives for different interests. With our study, we have found that the Revised Code in several areas has had considerable influence on Swedish corporate governance.

Since the 1970s voting behaviour has changed. Party identification and class voting has declined. As the electorate becomes more volatile, campaign strategy and party image becomes essential. Political communication and mass media now play an important role in election campaigns. Therefore, researchers take an interest in the impact of media on public opinion.

The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.

The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.

The aim of this work is to understand the recruitment of candidates to the local representative assembly in the municipality of Täby. The method used is qualitative interviewing, of a total of eight local politicians in Täby. The theory in which this work rest upon is based on a new-institutionalist perspective. Of great importance is the thoughts of the politicians involved in the recrution process, what do they think were the reasons that controlled the order of priority in the party list among the pool of candidates? Were there any obstacles for minorities in the politics like for example foreigners, women or young people? The study is taking it?s departure from the politicians who candidated in the election of 2002-2006 and the ones which are candidating to the election this coming autumn.In conclusion the aim is to understand the reasons that gives some of the candidates electable places to the assembly, and what the actors themselves think are the conclusive qualities that matters the most.

In an urban context where the water has a natrual place, and is used as a asset.

Bakgrund: Smärta är för intensivvårdspatienten en unik, subjektiv, obehaglig och flerdimensionell upplevelse. Intensivvårdssjuksköterskan har ett moraliskt ansvar att lindra patienternas smärta. Verbalt icke-kommunicerandepatienter kan inte skatta sin smärta med hjälp av Numeric Rating Scale (NRS). På en neurointensivvårdsavdelning (NIVA) i Stockholm har det beteendebaserade smärtskattningsverktyget- the Critical-Care Pain Observation Tool (CPOT), implementerats. Intensivvårdssjuksköterskorna på NIVA använder CPOT dagligen i sitt arbete.

The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.

The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.

This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Both authors of this study have been involved in the School of Business at Umeå University Student Association (HHUS) and is due this discovery deficiencies and problems within the association. The pressure to engage in HHUS is compared with other financial organizations around the country very low. This led us to consider why this is the case. From experience we know that communication between the association and its members are not functioning optimally. Communication itself is essential for motivating students and for that motivation should be high for the students to experience good quality on the engagement. The purpose of this study is to identify lines of communication and motivational factors that affect students who are members of HHUS to get involved or not.
