BACKGROUND: A Pressure ulcer means much suffering for many people. It also leads to big economical costs for the society. Therefore it?s of great importance to prevent pressure ulcers. If pressure ulcers are to be prevented nurses need to have sufficient knowledge about preventive strategies.

The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.

Syftet med uppsatsen är att analysera hur ett antal makrovariabler påverkar på och samverkar med priserna på småhus. Även hur variablerna reagerar på chocker sinsemellan studeras.Tidsserieanalysen bygger på månadsdata från år 1996 fram till 2006, som innehåller alla försäljningar av småhusfastigheter i hela Sverige. Det kvalitetsindex som används för att analysera priserna är K/T- talet. För att studera skillnader, avseende samverkan och påverkan, regioner emellan görs en uppdelning av landet i regionerna Stockholm, Göteborg, Malmö, Glesbygd samt hela Sverige. För att testa olika makrovariablers påverkan på K/T- talen används Grangers kausalitets test.

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

Upprepad testning vid inlärning förstärker långtidsminnet. Fenomenet är även känt som testeffekten (Roediger & Karpicke, 2006). Huvudsyftet med föreliggande studie var att undersöka testeffekten och jämföra den med inlärningseffekter av gruppdiskussioner. Andra syften var att undersöka om inlärning påverkades av individuella skillnader samt av testfrågornas komplexitet. Experiment genomfördes under fyra tillfällen och sammanlagt tolv studenter medverkade.

AbstractIt is unclear how L2 students acquire vocabulary ? how is it taught ? or wheather it can even be taught. In an SSL (Swedish as second language) program for young adults the ambition has been to integrate the L2 students? into the national high school (gymnasium) courses as quickly as possible, in order to meet the students? demands for subject education and to challenge them on an appropriate knowledge level. Teachers noticed quite early that the course ? integrated L2 students seemed to have a deeper understanding of words and an easier flow in their speech.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Ultrasound is still a relatively new method for the diagnosis of abdominal conditions in cattle. The objective of this study is to evaluate ultrasound as a diagnostic tool for the common diseases affecting high-producing dairy cattle, for example traumatic reticuloperitonitis, right- and left displacement of the abomasum, fatty liver, wound infections and abscesses. This paper is a combined litterature study and a report of the results from ultrasound examinations of bovine patients at the ruminant clinic at the Swedish University of Agricultural Sciences. The study includes two healthy cows from the ruminant clinic, and seven patients with abdominal related diseases. The examinations were made with a 2-6 MHz curvilinear transducer and both the right and left sides of the abdomen were scanned.

Arbetet har utförts på Ejendals AB i Leksand. Syftet var att ta reda på vilken inverkan stötdämpning i skor har på användaren och hur man ska anpassa stötdämpningen efter användaren. Genom intervjuer, enkäter och litteratur har kunskap om ämnet samlats in. I nästa steg genomfördes ett test på Clas Ohlsons centrallager i Insjön. 21 personer fick testa ett antal olika skor från Ejendals sortiment.

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.
