Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI. The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations. The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.

Under ventilprov vid kärnkraftverket Oskarshamnsverket 3 har oscillationsfenomen detekterats vid vissa driftlägen, främst i samband med stängning av någon av högtrycksreglerventilerna som reglerar ångflödet ut från reaktortanken. Syftet med detta examensarbete är att förklara uppkomsten av dessa oscillationer. För att kunna analysera problemet har en modell över reaktor och tryckregulator tagits fram. Detta har gjorts dels med hjälp av befintlig systemdokumentation och dels genom att skatta modeller av olika delar av systemet. Det har visat sig att det går att få fram en modell som skattar reaktortrycket ganska väl med ångflöde och neutronflöde som insignaler.

Megalaria grossa is classified as Near treatened on the Swedish Red List. It is also a so called signals spieces, e. g. a spieces that function as an indicator, signalling a forest that is worthy of protection. The aim of this study was to clarify the status at selected localities in the province of Uppland and Gotland.

SammanfattningScanias lastbilar har under de senaste åren haft en snabb utveckling när det gäller elektronik och styr - reglerteknik. En givare som inte har haft samma utveckling är yttertemperaturgivaren som introducerades i Scanias lastbilar 1987. Totalt finns det idag 10 olika ECU-system som använder sig av givarsignalen. Det har visat sig att yttertemperaturgivaren i Scanias lastbilar visar för högt värde i vissa körfall. Stora avvikelser på yttertemperaturvärdet har inte varit ovanliga när motorn har varit varm och lastbilen färdats i hastigheter under 30 km/h eller kör på tomgång, till exempel vid ett rödljus.

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

Russian comfrey, Symphytum x uplandicum, was tested as a plant nutrient source in a trial with tomatoes. Comfrey liquid was produced by Stiftelsen Holma i Höör. Tomato plants of the cultivar Aromata planted in a medium of soil:peat (1:1) enriched with organic nutrients and lime, were fed with comfrey liquid plus Biofer, in three different concentrations. Two different concentrations of BioRika were used as comparison, along with an unfertilized control group. In the comfrey treatment I a total amont of 1g N, 0,23 g P, 0,84 g K, was given to the tomatoes.

Magnetlager bygger på att med magnetisk kraft få rotorn att sväva så att den aldrig kommer i kontakt med statorn. Minimalt slitage och oberoende av smörjmedel hör till de största fördelarna med magnetlager. Marcus Granström har i ett pågående examensarbete visat att det är teoretiskt möjligt att bygga ett magnetlager. Marcus Granström har tagit fram en Simulinkmodell över processen inklusive regulator. Vidare finns flera olika tänkbara regulatorer föreslagna.Detta examensarbete är en fortsättning på Marcus Granströms examensarbete och utgår från de modeller som tagits fram.

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity. Many insects are attracted to the smell of fermenting fruit and associated microorganisms.

Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.

The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

AbstractThis essay is about what rights that a consumer has, after it?s been to a beauty-shop getting a treatment somewhere on her body. We were interested to see what kind of regulations that could be useful if a problem occurred after or during treatment. There are several risks with these treatments.The last decade these kinds of treatments have increased, due to people being vain and so aware about there looks. We started to investigate what type of rights the consumer generally has when it?s about a service.

Denna rapport handlar om optisk koherenstomografi, Optical Coherence Tomography (OCT), en relativt ny teknik som blivit allt mer attraktiv på sjukhusens ögonkliniker. En OCT-apparat används bland annat för diagnosticering av ögonsjukdomar lokaliserade i gula fläcken och runt optiska disken. I maj 2007 köpte Ögonkliniken på Blekingesjukhuset in en 3D OCT-1000 av märket Topcon. Hos denna OCT-apparat finns en mätfunktion, Caliper, som mäter näthinnetjocklek. Studien i denna rapport syftade till att ta reda på vad Caliper mäter, hur den mäter och om den går att lita på. En OCT-undersökning utfördes på tio testpersoner.
