Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method. Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.

This student report is about canine infectious skin diseases. It is primarily directed at veterinary assistans. The report includes a description of the skin?s structure and immunologic defences. The four types of allergic reactions are described. Different diagnostic techniques are also accounted for. The skin diseases included in the report are: fleas, lice, Sarcoptes scabiei, ringworm, Cheyletiella and leishmaniosis.

Atopisk dermatit är en sjukdom som drabbar ungefär en tiondel av världens hundar. Sjukdomen ger som följd av allergenexponering symptom såsom klåda, hudlesioner och otitis externa. Patogenesen för atopisk dermatit är komplex och multifaktoriell. Målet med denna litteraturstudie var att undersöka hur genetiska och immunologiska faktorer bidrar till sjukdomens patogenes. En obalans i T-hjälpar-(Th)-svaret vid atopisk dermatit är allmänt accepterad.

India is the country with the highest prevalence of rabies in the world, with about 20?000 human deaths occurring every year. The country also has a heavy burden of free roaming dogs, mainly because of the high amount of edible waste in the streets, which are the main hosts for the disease. Therefore to truly extinguish rabies, the main focus should be on the dogs, both stray dogs and owned. One method is to vaccinate all dogs against rabies.

This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.

There have been several projects with solar installations in Sweden, and Sala-Heby Energi (SHE) wanted to create a solar plant. The question answered in this thesis is whether it is economically viable to create such a source of sustainable, renewable energy. The plant would be built with the help of the financial effort from 120 customers. This economic union would sell the electricity to the SHE, for SEK 4.50 per kWh up to a certain level over a period of 10 years. It would be a long term commitment to environmentally friendly electricity, using solar cells which convert sunlight directly into electricity.In year 2009 there was introduced a new state aid for photovoltaic systems, to create an increased and continuing interest in solar cells.

Emhart Glass is the world?s leading manufacturer of equipment, controls and components to the glass container industry. The goal of this project has been to identify improvements and propose cost saving solutions when moving one of Emhart Glass work cells in Sundsvall. The changes shall result in improved work environment and increased product quality. The method contains value stream mapping, concept selection and P-FMEA and complies with Emhart Glass goal to become a more Lean focused business.

This paper describes how radiation affects the body, the somatic and genetic effect that can occure in exposure of ionizing radiation and how to protect yourself against it. How radiation affects the cells and why you can get cancer if you get exposed of a large amount of radiation is mentioned. Research after a threshold is mentioned and what Sweden does today to improve the radiation protection by laws and regulations. Explaining the atom, what radiation is and how the ionizing radation interacts with the atom. How backscatter affect the picture and the workers and how to protect yourself from backscatter is mentioned. Radiation doses, dosimetry and rules for those who practise radiation is shortly described..

Hästinfluensa, orsakat av ekvint influensavirus (EIV) förekommer över hela världen och är en vanlig respiratorisk sjukdom hos häst. Nyligen upptäcktes att EIV passerat djurslagsbarriären och orsakat sjukdom hos hund, vilket har lett till utvecklingen av canine influensavirus (CIV). Detta har sannolikt skett via direkt överföring utan föregående mutation av viruset. Flera faktorer spelar in i processen men den viktigaste tycks vara att häst och hund uttrycker samma typ av ytreceptorer i luftvägsepitelet (SA?2,3Gal), vilket möjliggör för EIV att binda in till och infektera cellerna hos både häst och hund.

Kennelhosta är ett samlingsnamn för en grupp virus- och bakterieinfektioner som ofta drabbar hundar som är tillsammans med större grupper av andra hundar. Symptomen är oftast milda, vanligtvis med en torr, hackande hosta, men kan i vissa fall ta sig uttryck som svårare symptom som lunginflammation. De vanligaste infektionsämnena är hundens parainfluensavirus (CPIV), hundens respiratoriska coronavirus (CRCoV), hundens adenovirus typ 2 (CAV-2) och bakterien Bordetella bronchiseptica. Hundens respiratoriska coronavirus är det virus som undersöktes i studien som ligger till grund för den här rapporten. Familjen coronavirus innehåller de största membranomslutna virusen med RNA som arvsmassa med genomstorlekar på upp till 32000 baser.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

Inom Försvarsmakten används motordrivna generatorer för att förse många förbandsenheter med elektricitet. Dagens bullriga och vibrerande elverk är idag möjliga att ersätta med tystare bränsleceller. På köpet erhålls en bättre ergonomi för alla som arbetar i hytter som strömförsörjs av elverk. I rapporten redovisas funktionen för olika typer av bränsleceller, vilka bränslen de använder sig av och hur dessa kan transporteras. Dessutom redovisas hur två elverk används och vilka förbättringar som kan åstadkommas vid byte till bränsleceller.

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.
