This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the Total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the Total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of Total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.

The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.

The aim of this study was to investigate if the hen?s genotype, age and diet affect fat components in egg yolk. The fat components measured were total fat content, phospholipids, cholesterol and the fatty acid profile. This trial involved 12 groups of laying hens housed in 8-hen cages enriched with perches, dust baths and nests. The genotype Lohmann Selected Leghorn (LSL) and the genotype Lohmann Brown (LB)was used.

By reading earlier research on Generation Y, content marketing and on social media during the working process the problem has gradually changed, in accordance with an abductive research approach. The study focus has developed from examine marketing methods on marketing towards Generation Y to include on what social media platform Generation Y is most susceptible for content marketing.The purpose of this study is to help companies whose target market is Generation Y to aim their content marketing through the right distribution channels, to save time and money. To meet this objective and to answer the main question of this study, empirical data was collected through a web based, quantitative survey which was completed by a total of 301 respondents, all of them belonging to Generation Y. The collected quantitative data was contrasted with existing theory and was analysed.The study concluded that Facebook is the social media channel where Generation Y feel most susceptible for content marketing, followed by YouTube. .

Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

In this study we examine to what extent people with disability participate in television news and how they are represented. We chose to examine one broadcast per day of SVT Public Service news program Rapport and commercial channel TV4 Nyheterna (TV4 News) during one month using quantitative content analysis and qualitative discourse analysis.We found that people with disability are underrepresented in television news. In Rapport only 1,9 percent of the total broadcasting time contained people with disability and in TV4 Nyheterna 3 percent of the total broadcasting time contained people with disability. In the news people with disability were often represented as stereotypes, most commonly as victims. The focus was often on the medical aspect of the disability and on the problems that people with disability had.

The purpose of this study is to show which content that is most common in the Swedish News Agency TT Nyhetsbyrån?s sports coverage. It also shows if the coverage is concentrated to for example any special sports, clubs, people or topics.This study uses a quantitative content analysis and the result is based on texts from 28 systematically selected days during one year. In total, the study includes 906 texts.The result of this study shows that the sports content of TT Nyhetsbyrån?s news feed is mainly concentrated to two sports, football/soccer and ice hockey.

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.
