The paper?s focus is on Max Hamburgarerestauranger AB?s incentive system, that is directed to the managers of all of its restaurants.We had interviews with the CEO, as well as the head of the Economics Department of Max H.
Akut prostatit hos hund : en retrospektiv studie av ultraljudsbilden på 15 hundar med kliniska tecken på akut prostatit
Acute bacterial prostatitis is a common disease in older male dogs. It gives symptoms such as fever, pain, tiredness, infertility, unwillingness to mate and sometimes symptoms from the urinary tract. It is common that you do an ultrasound exam on dogs when you suspect prostatic changes.
In this study 15 dogs diagnosed with acute prostatitis at the small animal clinic at SLU in Uppsala were examined. The clinical signs and the ultrasound pictures were put together in retrospect.
Dexametasons effekt på trombocytaggregering och syreradikalproduktion
Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Analys av turbulensmodeller för CFD
This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.
?När man gick därifrån så kände man det här äklaranamma!? : fyra föräldrars upplevelser av Råd- och Stödsamtal
The aim of this study was to increase our knowledge about how the ?Conversational-contact with the social services? is experienced by the parents who attend it. The research was based on a qualitative method consisting of four individual interviews.Main issues of the study:? The parents experience of the content of the meetings with the social workers? Do the parents experience that the conversational-contact has contributed to some changes in their lives?Results indicated that all parents were positiv to the conversational-contact. Afterwards they felt more secure and stable both as persons and in their role as parents.
BarnABC
This project is a learning CD-ROM production aimed at first-time parents. It is
using both sound and images, moving as well as non-moving. The purpose of the
production is to be an interesting alternative to traditional books. We have
been looking at similar productions like drivers license educational CD-ROMs
and encyclopedias for inspiration and ideas on how to proceed. In order to give
the content some dynamics, we've also added the element of 3D-animated
sequences.
The application is supposed to be run as a simple executable file with flash
embedded.
Magomvridning hos hund : akutsjukvård och postoperativ intensivvård
The aim of this literature study was to give a clear picture of what gastric dilatation-volvulus is, and how the acute- and postoperative treatment and care is managed. The general aim is to support and help the veterinary technicians in their clinical work.
Gastric dilatation volvulus is always an emergency. The primarily goal when these dogs are hospitalized is to establish an adequate cardiovascular function. This is done by immediate intravenous fluid therapy followed by decompression of the dilated stomach.
Framgångsfaktorer i ett fallförebyggande arbete inom hemtjänsten
In 2005 over 48 000 senior citizens fell so badly that the needed medical care and almost 1200 of them died. This makes falls in the elderly one of our biggest public health problems. Research in this area is extensive and although we know what causes a fall and how we in theory should work to prevent their occurrence, this is a problem that is increasing. There seems to be a gap between research and practice, and research into why this gap occurs is very narrow. The purpose of this study was to identify success factors with fall prevention from a staff- perspective.
"Man borde kanske prata med de man tycker illa om" - tre elevgruppers arbete mot rasism
The aim was to investigate three anti-racist groups of pupils, their thoughts about respectively their work against racism. The aim was divided into the following questions: - What is, according to the groups, racism and what does the situation look like at the schools? - What does the dynamics in the group look like? - What courses of action are the groups using and how can they improve their work? - How can the groups be described according to the terms work group and basic assumption group? To answer these questions I made three group interviews, one with each group. I analysed the results partly according to earlier research and literature, partly according to the group theory of WR Bion, using the terms work group and basic assumption group. My conclusion is that the word racism seems to have been affected by inflation, since the groups include bullying as well as anti-racists.
Empire and Multitude - Den globala klassanalysens nya subjekt?
This essay contains a comparative analysis of Erik Olin Wrights Marxist class analysis and Michael Hardt and Antonio Negris post-Marxist class analysis as presented in their books ?Empire? and ?Multitude: War and democracy in the age of Empire?. I discuss the shift in analytical focus from state level to global level that Hardt and Negri's analysis represent and the ensuing relevance of this for contemporary class analysis. The essay also address the challenge and implications posed to class analysis by the ever increasing economic globalization, from a material production to an ever growing immaterial service economy and the decrease in state power in controlling capital and labor movement. I propose that analytical understanding of class conflict help us to a better understanding of the mechanisms and dynamics that generate social and economical inequalities and that an updated Marxist class analysis still have much to contribute to our understanding to how these issues not only shape our society but also our capacity to counteract them..
Konceptstudie av Waste Heat Recovery System på Tunga Fordon
In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
