Tollarsjuka hos hund : en retrospektiv studie med journalsammanställning av 18 hundar

?Tollarsjuka? is a disease with a suspected immunopathological background seen in Nova Scotia duck tolling retrievers. Pyrexia, lameness, stiffness and joint- or musclepain are typical clinical signs. The purpose of this study is to describe case histories from dogs with a possible evidence of ?tollarsjuka?. 18 private dogs were included in this report. Generalised stiffness, lameness and fatigue were the most frequent manifestations of the disease.

Utförande av och uppfattningar om postoperativ vätskebalans inom ortopedisk vård : En interventionsstudie

SAMMANFATTNINGSyfte: Syftet var att beskriva sjuksköterskors och undersköterskors dokumentation och uppfattning om dokumentation av vätskebalans vid postoperativ vård på en ortopedisk vårdavdelning före och efter ett undervisningstillfälle.Metod: Studien som genomfördes var en kvantitativ interventionsstudie med en enkätundersökning och journalgranskning. Interventionen bestod av undervisning i ämnet vätskebalans. Enkätundersökningen genomfördes före och efter utbildningen med 11 respektive 8 deltagare. Före och efter utbildningen granskades 60 patientjournaler (n=120).Resultat: Enkätundersökningen visade att sjusköterskorna och undersköterskorna ansåg att arbetet med vätskebalans var viktigt för patienten, men en förändring i avdelningens rutiner var önskvärd. Ingen förändring i uppfattningen om arbetet med vätskebalans kunde ses hos sjuksköterskorna och undersköterskorna efter utbildningen.

Rotavirus zoonotiska potential : kan infekterade föl smitta människa?

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Equine metabolic syndrome

Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.

Utvärdering av radiologiska kriterier för att bedöma tillståndet ileus på hund :

Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. Obstruction of the small intestine is best diagnosed by using radiography, contrast-study if needed, and ultrasound. To avoid further examinations, diagnosis from plain radiographs is preferable. One of the signs of illness one can detect from these examinations is a dilation of the small intestine proximal of the obstruction, caused by gas or fluid; ileus.

EN SKOLA I FÖRÄNDRING : En studie av en ny åtgärd - språkregeln

Focus of this study is an examination of the Swedish school today, its transformation and complexity when also the community outside of school undergoes changes in shape of among other things a different population composition and new political ideas. More specific the aim of the study is to understand how Gustav Adolfsskolan in Landskrona, a compulsory school in south of Sweden, legitimates the language rule that is in effect in the school. It?s a relatively new measure undertaken in the school and both the problems in the school and this measure have been widely discussed in the public media. The theoretical sources of inspiration have come from Weber, Galbraith and Elias and include power relations and dynamics within social mobility when people establishes in new places.

CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Tryck här för sanningens ögonblick: Automatiserade och mänskliga servicemöten i komplexa tjänsteleveranser

As self-service technologies become more common in service provisions, a deeper understanding is needed of how customer satisfaction is affected by automated service encounters. Drawing from theories of customer satisfaction, human interaction, and the dynamics of complex service provisions, the differences between automated and interpersonal service encounters in the initial part of a service provision are examined in terms of customers? evaluation of the service encounter itself, overall satisfaction, as well as the service encounter?s impact on global evaluations and evaluations of other non-dependant service encounters. The study was performed on people travelling by air on Swedish domestic routes. Passengers were asked to evaluate the airline?s performance on different attributes of the air travel they had undertaken, as well as to form an overall evaluation of the service.

Mångfald i grupparbete : Hur påverkar det lärandet?

The purpose of this study is to answer how teachers look at diversity in groups, with learning in focus. For this study I chose different high-schools in Sweden teaching Moving Pictures, in Swedish 'Rörlig bild'.These are the research questions: 1) What advantages and disadvantages do the teachers see with homogenity and heterogenity in their groups? 2) Which ascpects of teaching do the teachers bring up when talking about diversity?The method of this study has been a qualitative analysis and investigation in questionnarie form, with qualitative questions. Teachers were asked and data was examined with help of theories in diversity, group work, group dynamics, homogenity and heterogenity by authors like Toseland, Jones and Gellis (2004), Forslund Frykedal (2008) and Hammar Chiriac (2008).It is noticable that the teachers thought of differences in terms almost exclusively of school ability. The result is: - As a whole: homogenity means security, heterogenity means creativity.

Halvledarreläer

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
