The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.

SammanfattningBakgrund:De senaste åren har förekomsten av sömnstörning ökat. I Sverige anses det numera vara ett av våra stora folkhälsoproblem. Sömnstörning har visat sig vara mer förekommande hos individer med samtidig sjukdom än hos den allmänna populationen. Brist på sömn medför ofta dagtidssymtom vilka påverkar individens tillvaro. Sjuksköterskan är ofta, främst på sjukhus, den första som möter patienters problem gällande sömn.

Detta examensarbete behandlar utvärderingen av en testbana för excitering av vibrationer i fordonskupé. Utvärderingen fokuseras på hindren i körbanan som ger upphov till de önskade excitationskrafterna. Konstruktionen av hindren genomförs med hjälp av CAD-programvaran Autodesk Inventor 2009. Simuleringarna genomförs med hjälp av programmet ADAMS/Car. En inbyggd fordonsmodell i ADAMS med tillhörande komponentmodeller används och varieras under simuleringen för att analysera kraftimpulser för olika fordonsindividuella kombinationer.

This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).

In my work as family counselor I have long seen a pattern with many of the couples I?ve met. Thepattern consists of a movement where one person take an offensive, accusing and sometimeschasing position, whilst the other person is on the retreat. Over and over again I?ve made theexperience that if you help them solve a single problem another one pops up.

ABSTRACT. Mastitis is one of the most common diseases affecting dairy cows worldwide. In Sweden annu-ally about 60% of the dairy cows get infected and Staphylococcus aureus cause approximately 30% of these infections. Mastitis causes enormous economic losses. In Sweden, the costs to cure mastitis are estimated to be 192 million SEK per year, excluding the costs for mastitis prevention.

The modern silvicultural practices of today, with cutting by compartments, have led to a large benefit for the moose population through the cleared areas which produces large amount of fodder. This new landscape can produce and feed a large moose population. But it will cause a conflict effect towards the landowners; the conflict consists of browsing mainly in the young pine forest. The result from browsing and damage will be sparse stands with reduced growth and technical damage like leader shoot browsing, stem breaking and damage of the bark. Technical damage can kill the tree or damage it so hard that it would not work as future saw timber.

Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
