Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.
Varför svänger stenen? : En studie i curlingens komplexa tribosystem
The tribo system ice-curling stone was investigated in order to understand the mechanisms behind the stones' behavior on the ice sheet. The problem with non-identical stones should also be addressed.The stone curls, that is, its sliding path deviates from a straight line to the right for a clock-wise rotation and to the left for a anti-clock-wise rotation. Several mechanisms to explain this behavior have been proposed over the years but none has been successful.By carrying out experiments at the local curling rink and studying silicon castings of ice- and stone-surfaces with scanning electron microscopy and vertical scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The contact between stone and ice is never completely dry, nor in the hydrodynamic lubrication regime. It is probably a combination of hydrodynamic lubrication and a contribution from mechanical scratching of the ice.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Hur rör sig polisens tjänstehundar? : en pilotstudie gällande tjänstehundars rörelsesymmetri mätt med tryckmätningsmatta
SammanfattningBakgrundDet är i Sverige svårt att tillgodose behovet av cirka 450 tjänstehundar och gällande hälsa är uppfattningen bland användarna att hundarnas fysiska hållbarhet blivit sämre. Med hänsyn till att det lider brist på tjänstehundar och att de tas ur tjänst tidigare än önskat vore det av stort värde att kunna förlänga en polishunds tjänstgöringstid. Ett sätt att förverkliga detta kan vara att använda undersökningstekniker vilka tidigt kan fånga upp lindriga förändringar i rörelsesymmetri, förändringar som kan vara ett första tecken på smärta. En tryckmätningsmatta kan registrera små förändringar i hur hunden belastar sina ben, förändringar som är svåra att se med blotta ögat. Det kan därför vara av intresse att ta fram ett normalmaterial för tjänstehundar så att det med tryckmätningsmattans hjälp tidigt går att upptäcka om en stoisk tjänstehund har ett förändrat rörelsemönster.Syfte & hypotesSyftet var att använda en tryckmätningsmatta för att skapa ett normalmaterial för en tjänstehundspopulation gällande parametrar registrerade med tryckmätnings-mattan.
I gränslandet till demokrati och europa - En studie om Ukrainas förvaltning
After the orange revolution in Ukraine, hope was given to achieve fullydemocracy in the whole society. However, this has not been the outcome; theUkrainian public administration still has problems to deliver what the societydemands. By answering the question: ?Which problems have the publicadministration to become democratic and how can we explain them??, we analyzethe failures within the public administration to accomplish democratic procedures.The empirical material in this thesis is mainly obtained from interviews andresearch during a field study in Ukraine. The problems for the civil servants inUkraine to act as guardians of the society are strongly connected to an inadequateprofessional knowledge.

Furthermore, we show how brands can make use of trends in a brand establishment.This paper is written from a qualitative approach. Through both structured and semi structured interviews, we obtained valuable information from our respondents. Our frame of reference and empirical foundation are linked together through an abductive approach which has resulted in our analysis and conclusions.A trend brings with a set of emotional characteristics, which companies can?t influence but must adapt to.
Diatermirök- Det perioperativa teamets arbetsmiljö
BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

These patterns and keywords are then analyzed to arrive at the study's results.Results and contributions: Our results suggest that all the identified benefits, customer engagement, customer insight and communication are driving forces to make use of social CRM.
Co-opetition - Rollkonflikter i gränsöverskridande arbetskontexter
This thesis revolves around co-opetition and boundary spanning activities with IETF (Internet Engineering Task Force) as research case. The main objective is to through qualitative interviews and a passive observation of email conversations explore how the participants of IETF experience and is affected by a double membership where they sometimes are cooperating with their competitors. Theories states that boundary spanning activities can create role conflicts for these participants when different role-senders, IETF and the employer, send incompatible expectations. We also believe that this can have a negative impact on discussions and the standard development process, which is why we are conducting the passive observations mentioned above.The result shows that the environment of co-opetition is a contributing factor to role-conflicts. These conflicts appear when participants are forced to choose between the role as an employee and the role as an IETF participant.
Bibliotek i kristider: Perioden 1930-1945
In 1930 a new library reform came into force, which in reality was the beginning of the modern Swedish library. The purpose of this reform was to take measures to promote efficiency, for example to increase library co-operation. The Government grants were at the same time raised considerably. However, as early as in 1930, but especially the following year, the depression hit Sweden. The Government reduced the grants until the first half of 1936.

Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :
Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals.
A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact.
Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial.
The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.
