The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

The intention of this final thesis is to examine how to create a schoolyard that inspires children at the age of 6 ? 12 years to play and give them possibility to develop. To get a lot of knowledge in this subject, I have combined studies of literature with practical studies at Hosjöskolan in Falun. During my practical studies I have done interviews, walks in the area with the children and visited other schoolyards. I have based a design proposal for the schoolyard of Hosjöskolan on these studies.

Sammanfattning Eftsom kalla Sverige blir mörkt ganska tidigt på kvällen på höst, vinter och vår ville jag se hur man kunde förlänga användandet av det lilla trädgårdsrummet både i tid på dygnet och i tid på säsongen. Jag tycker att ljussättning är en viktig del av gestaltningen, belysningen gör trädgården levande. Mitt syfte med arbetet var att skaffa mig grundläggande kunskap om ljussättning och ljuskällor, för att sedan skissa på koncept för det lilla trädgårdsrummet. För att lyckas med detta behövde jag ta reda vad ljus är och hur det fungerar. Ljuset har många olika egenskaper, t ex olika våglängder, och färger.

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

The Swedish carrot market is dominated by a few big companies and three of them stands for 50 % of the market. During the last twenty years the number of growers has decreased, the area and the harvest have increased. The big producers have invested in advanced and expensive postharvest equipment that fulfils the high standards of the food industry. Few carrot producers are members of an organisation and they keep contacts with there buyers one by one. The buyers are mostly wholesalers and these have during a long period of time decreased the number of suppliers.

This is a 20 credit Master thesis within the landscape architecture education at the Institute for Landscape Planning at the Swedish University of Agricultural Sciences at Alnarp. Norränga is situated on the fringe of the city of Lund, east of the existing district of Linero.The city planning office of Lund municipality has come up with a ?in-depth comprehensive plan? for the exploatation of the eastern area of Lund. The plan concerns an area of 1035 square kilometre which contains at least 1500 nya buildings, two schools, primaryschools, stores and bus station for local bus traffic and the new bus line - Lundalänken. The townplan is inspired from the historical Square block city with defined street system. The municipality has visions of what the green areas should consist of.

The purpose of this master thesis is to investigate the influencing factors on the businesspotential of products with health claims, using PrimaLiv as an example. And togive recommendations on how a dairy producer, which is present in the Swedishmarket, could improve the sales rates of products with health claims. We have chosento put a main focus on the consumer, as he or she determines the business potential.This is an unusual approach since most studies cover the producer?s perspective. Wethereby wish to contribute with new knowledge on the area in question.

Abstract: In the past ten years in Sweden, the numbers of people between the ages of 16-19 who were unemployed or not in upper secondary school education have increased. This was assumed to be caused by three factors. Firstly the upper secondary school education reforms in 1992, secondly a substantially reduced labour market for young people without the upper secondary school education and thirdly an increase in demand for work experience.Our purposes was to describe the effects on the outsiders through a document analysis study, but also to understand which individual, social and structural causes that were thought to increase the risk of marginality. Our second purposes were to understand how the Kristianstad community worked to prevent young people of ending up as outsiders. Through interviews with local authorities, we tried to find out if the Kristianstad community lives up to their responsibility of looking after people less than twenty years of age.Our conclusion was that, although the Kristianstad community seems to have a good system, the community has the highest number of unemployed in the county of Skåne.

The main purpose of this M. Sc. thesis is to increase the knowledge about managing urban forestry for recreational use. The analysis is focusing on differences between visitors? experiences in the north and south of Sweden, represented by Nydalasjön and by Härlanda tjärn.

The aim of the study is to examine factors influencing students? feelings of pleasure or pain associated with school mathematics. Own experience of students? frustration about mathematics and concern about students not reaching desired goals is the driving force in this study. It contributes with knowledge from the students' perspective.

Sammanfattning Ensilerat vallfoder är ett av de absolut viktigaste fodermedlen för att förmå korna att producera en stor mängd högkvalitativ mjölk. En hake är dock att ensilaget ska vara av god kvalitet och med bästa möjliga näringsvärde, samtidigt som man även vill ha volymmängder. För att få detta gäller det att skörda vid rätt tidpunkt, vilket kan vara svårt att veta när det infaller. Till detta finns ett hjälpmedel som kallas skördetidsprognos. Detta går ut på att man klipper prover i vallen upp till tre gånger innan första skörden för att analysera gräset och därigenom kunna avgöra när bästa tiden är för att skörda för att få den mest optimala kombinationen av mängd och näringsvärde. Syftet med detta arbete är att undersöka hur bra hjälpmedel jordbrukare i norra Sverige tycker att skördetidsprognosen är för att få en ökad kvalitet på ensilaget, samt att jämföra variationen i näringsvärde och mängd biomassa inom och mellan olika fält.
