Ledinflammationer på häst och intraartikulär behandling med hyaluronsyra : en pilotstudie på hyaluronsyra X
Traumatic arthritis is a common cause of lameness in horses. One of different treatment alternatives of arthritis, is intra-articular injection with hyaluronan. As knowledge about pathophysiology of arthritis and function of hyaluronan is increasing, understanding grows about the mechanism of hyaluronan action in joints. Hyaluronan has, in addition to effects on viscosity, anti-inflammatory and analgesic effects. Extensive research and scientific studies have been made on exogenous hyaluronan.

Behandlingseffekt av rituximab jämfört med infliximab vid reumatoid artrit
The aim of this study was to compare the effect between the drugs rituximab and infliximab in rheumatoid arthritis (RA). RA is an autoimmune disease that affects the peripheral joints and is associated with exacerbations. Various immune reactions in the body cause inflammation of the joints which further results in cartilage and bone damage. The diagnosis is made by the classification system "The 2010 American College of Rheumatology (ACR) / European league against rheumatism (EULAR) classification criteria for rheumatoid arthritis", which is an update of the older system called "The 1987 American College of Rheumatology classification criteria for RA". Approximately 0.5-1% of the population is developing the disease, but it varies slightly between different parts of the world.
Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
Vegetarisk kost - ett möjligt behandlingskomplement för symtomlindring vid reumatoid artrit?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: A vegetarian diet, a possible treatment complement for relief of symptoms ofrheumatoid arthritis? A systematic review.Author: Alexandra Ahlsén and Caroline ForsbergSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background: Rheumatoid arthritis (RA) is a chronic remitting polyarthritis that is relapsing.Symptoms are inflammation of the joints with pain, stiffness and degradation of joint tissue.In some cases, also other parts of the body are involved. The treatment consists ofmedications to reduce pain, inflammation and degradation of joint tissue. Today, the offerednutritional treatment is primarily focused on meeting energy requirements and nutrient needs.The diet has also been discussed as symptomatic treatment, and one of the factors believed toinfluence the symptoms is meat.Objective: To assess the evidence as to whether a vegetarian diet affects the symptoms ofrheumatoid arthritis, and if so, to suggest how it can be implemented in practical dieteticswork.Search strategy The databases used in the literature search was PubMed, Scopus, and AMED.The search words used were: "rheumatiod arthritis", "vegetarian", "vegan", "diet", "meat" and"animal protein".Selection criteria: Studies investigating a vegetarian diet on the symptoms of RA wereincluded. Only RCT, clinical trial, controlled clinical trial, human studies and original articlesin English or Swedish were included.
Lokalisationen av osteochondrosförändringar hos svenska halvblodshästar :
The aetiology of osteochondrosis (OC) is known to be complex and multifactorial. The occurrence of bone fragments in joints and their connection to osteochondral disease are no exception. In the hock and stifle joint of the horse this type of lesion has generally been considered to be of osteochondral origin, while the process behind these fragments in the fetlock joint has been up for discussion.
The objective of this study was to determine the frequency and the localisation of OC in Swedish warmblooded horses. In order to do so all radiographs of stifle, hock and fetlock joints performed on Swedish warmblooded horses during the period of 1992-1999 at Regiondjursjukhuset in Helsingborg were examined and the material was divided into two groups.
Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
Identifiering av stelkroppsmodell för industrirobot
In this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results..
En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur
This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.
Fiberföstärkning av Limträbalkar
Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
Ledhälsostatus hos Shetland Sheepdog : en enkätstudie
Background
The Shetland Sheepdog is a popular breed of dogs in Sweden. The breed is mostly used as a companion dog and is also popular within certain dog sports such as agility. The Shetland Sheepdog is not included in any breeding programs regarding joint health. The animal insurance company, Agria had recently informed the Swedish Shetland Sheepdog Club (SSSK) that they had noted an increasing number of arthritis in the elbow joints, therefore they wanted to exclude elbow joints from the insurance until SSSK started a breeding program against elbow dysplasia. After the start of this study Agria withdrew their demand, but the study went on as planned.
Aims of this study
The aims of this study was to investigate if there is any data that may show if there is a larger or smaller reason than before to suspect that the breed has a problem with elbow dysplasia and therefore would benefit from a breeding program regarding this.
Limmade träförband
Utvecklingen av förbandsmetoder är viktigt för att utveckla konstruktionslösningar. Under det senaste decenniet har forskning på limmade förband utförts, främst på inlimning av stålstag och plattstål i limträ. Förhoppningen är att spänningen ska fördelas jämnare i förbandet och att brott ska kunna undvikas. Hypotetiskt sett skulle det kunna göra knutpunker utan synliga förband möjliga vilket även skulle gynna arkitekternas önskemål.Genom en sammanställning av tidigare forskning dras en jämförelse mellan testresultaten och en antagen knutpunkt som belastas av egentyngder och variabla laster. På så sätt kan limmets kapacitet konkretiseras.
Stenebergs sockerbruk: en fallstudie av en timmerstomme fr?n 1739
Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in
1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood.
Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there
exists today a surprisingly low amount of documentation of the building itself. In order to
enhance the existing and lacking building documentation, this case study aims to shed light
on the building's log-timber built frame, focusing on how it was constructed, how the long
lengths of its walls were handled and what type of joinery and tools were used.
A thorough investigation of the building is conducted on site, followed by gathering of
information which is then presented through text and illustrations. The findings indicate the
orientation of timbers, location of joints and scarfs as well as tool marks which together
contribute to the forming of a basis of understanding of the building's construction..
Ledpatologin hos 10 ungsuggor som uppvisat hälta och/eller förlamning
On average half of the sows in Swedish piglet producing herds are culledannually. A significant portion of the sows are euthanized because of lameness orparalysis. Young sows and gilts are overrepresented in the category of animals,culled due to injuries in the musculoskeletal system. These injuries cause pain tothe animals. Early culling of sows/gilts also have economical consequences forthe producers.
