Långtidsuppföljning och artrosutveckling hos hundar kirurgiskt behandlade för ruptur av kraniala korsbandet :
The high incidence of cranial cruciate ligament injury in dogs results in both
suffering and significant costs due to treatment and care of affected dogs. Today
there are several different technics for surgical treatment in dogs with ruptured
cranial cruciate ligament. At University Animal Hospital (UDS), SLU, in Uppsala
two fundamentally different methods; TPLO (Tibial Plateau Leveling Osteotomy)
and external fixation with suture material are practiced.
The aim of this study was to estimate if the different surgery technics result in any
difference regarding the function of the dog in a long term perspective. Since
motion and function are very affected by arthritis, was the purpose also to
determine if there are any differences in developing arthritis between dogs
surgical treated with external fixation respectively with TPLO. Development of
arthritis is common after surgery or traumatic injuries in a joint, such as cruciate
ligament rupture.
Unfortunately was the number of dogs in the study to small to achieve two
comparable groups.
Bibliotekscheferna och bibliotekarieutbildningen. En enkätundersökning av bibliotekschefers syn på utbildningen i biblioteks- och informationsvetenskap i Sverige
The aim of this thesis is to investigate what chief librarians in Sweden know about the present education in Library and Information Science and what opinions they have of it. We have used the following four questions as a starting point for our work: + How much do the chief librarians know about the education in Library and Information Science? + What are their opinions of the education? + What emphasis do they put on academic degrees and practical experience? + Are there any differences between various kinds of libraries regarding these issues? We decided to use questionnaires to gather our information. These were sent to 200 chief librarians on both public and research libraries all over Sweden. 151 of the questionnaires were answered.
The effect of training on spontaneous blink rate in dogs
The spontaneous blink rate is found to be a non-invasive but functional, reliable and useful way to monitor central dopaminergic activity. Dopamine is associated with a range of functions such as reward, motivation and learning. It plays an important role in goal-directed behavior and in maintaining a behavior once a task is learned. As far as the author knows, there are today no publications that discuss the topic regarding the possible link between training and spontaneous blink rate in dogs. Therefore, eight privately owned dogs were included in this study to determine if there was a significant difference in the spontaneous blink rate before and after the process of learning a task.

Budgeten som styrverktyg ? En studie av Blekingesjukhuset i Karlskrona och S:t Görans sjukhus i Stockholm
Vårt syfte är att undersöka om och hur budgetens roll skiljer sig åt mellan en offentlig och en privat hälso- och sjukvårdsorganisationer. Vi har baserat vår uppsats och våra slutsatser på intervjuer, som vi gjort på Blekingesjukhuset i Karlskrona och S:t Görans sjukhus i Stockholm. Vi har gjort intervjuer på fyra till fem olika nivåer i båda organisationerna, för att få ett djup i vår undersökning. Vi har kommit fram till att det finns stora skillnader mellan det offentliga sjukhuset och det privata sjukhuset. Den största skillnaden fann vi vara budgetuppföljningen, men att det inte finns någon större skillnad mellan sjukhusen på lägre nivå, däremot på högre nivåer kan vi urskilja relativt stora skillnader.

OLIKHETER I SKOKURATORERS BEDÖMNINGAR - EN VINJETTSTUDIE OM TOLKNING, BEDÖMNING OCH AGERANDE
From my own experience as a school counselor I have learned that the decision making processes in terms of supporting and helping the students is extremely hard and very individual. In different situations, a different approach between individuals is present. I thought about which factors effects the school counselor?s way of handling problematic situations. I soon realized that the individual has a great effect on the work itself.
Konstruktionen av en diversifierad normalitet : En studie av hur det interkulturella perspektivet kan yttra sig i några förskolepedagogers didaktiska överväganden och praktik.
The aim of the present study is to describe and analyse how an inter-cultural perspective presents itself in the didactic considerations and in the practice of preschool teachers on a multiethnic preschool.The theoretical perspective upon which the study is founded is social constructivism, but in addition to this Ingegerd Municio?s idea of two existing discourses present within the institutions in the Swedish educational system, as well as René León?s concept of a diversified normality, has been used as theoretical tools and points of departure.The empirical investigation consists of a qualitative field study at a multi-ethnic preschool, where participating observation and group interviews have been used to collect data. In these teachers from the preschool have participated.The results and the analysis of the data show that an inter-cultural perspective surfaces in the didactic considerations and in the practice of the preschool teachers in their construction of a diversified normality. The diversified normality thus constructed is constituted through different social processes. I have here identified the following ones: the preschool teachers emphasize differences among the children in general, they allow that the children behave differently and they allow them to be different; they recognize ?cultural? differences, differences in origin, and frames of reference, and they recognize that the children at the preschool are bilingual..

Elektronisk motorstyrning för ottomotorer
The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.
