en fältstudie för att bestämma lämplig undersökningsdag och frekvens på ultraljudsproben
… make on day 22 than on day 25 since most of the not pregnant cows then were in heat. Because of the low number of not pregnant heifers, it was not possible to determine what day these were easier to diagnose. The pregnant animals were easier to diagnose at day 25 because of more …
… Spillvärmen tas till vara i en anläggning kallat AHR-torn. AHR står för Aqua Heat Recovery: alltså värmeåtervinning med vatten. Torkluften passerar i detta torn flera steg av värmeväxlare där värmen avges till vatten som strömmar i batterierna. De två nedersta stegen i tornet …
Endurance training in the heat for firefighters - a pilote study Acklimatisering är en psykologisk och fysisk process då en anpassning till en ny eller förändrad omgivning sker efter en regelbunden exponering till en viss miljö. Träning för att främja värmeacklimatisering för …
A feasibility study
… low power consumption since they are close to the load, which is sensitive to heat. Different amplifier architectures were investigated to find a suitable circuit for the given prerequisites. In this report the advantages and disadvantages of voltage and current feedback are …
Idag värms glasugnar upp med antingen gasol eller olja, detta projekt vill visa på möjligheten att istället använda gas från biobränsleförgasning som förbränns utan synliga flammor. Detta skulle miljömässigt ge fördelarna att biobränslen inte bidrar till växthuseffekten och ge …
… A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and …
… streptococci group G. The infection was spread among the animals when their heat statuses were checked intra vaginally with an impedance meter. After treatment with L. reuteri both intra vaginally and supplied in the drinking water no animal has been found to carry the …
… easy soluble protein, and would get a better composition of the protein after heat-treatment. The product Expro from rape is an example of that.
… to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of …
… Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat. Fore every batch the water content during harvest and after drying, were measured. Tests were also done for microbes and germination. The six batches were harvested at …
At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of …
Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be …
