Stora företagsbedrägerier och skandaler såsom Kreuger, Enron och Worldcom där fordringsägare led omfattande förluster, följs ofta av en debatt om revisionens syfte och omfattning. Efter påtryckningar från EU om att minska den administrativa bördan, öka konkurrenskraften och stimulera Europas ekonomi, avskaffades revisionsplikten för mindre aktiebolag i Sverige 2010. Fordringsägare i form av bland annat kreditgivare och investerare är parter som kan drabbas vid en konkurs och har därför behov av att ha en fungerande relation med företaget. Tillsammans med kompletterande information från revisorer bidrar kreditbetyg till en bättre bild av kreditrisker som fordringsägare utsätter sig för. Syftet med studien är att öka förståelsen för revisionens betydelse i värderingen av ett litet företags betalningsförmåga när det sedan 2010 inte längre är ett lagstadgat krav att ha revisor.

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.
