Yngre järnålder till medeltid i Blekinge Östra Härad : En järnåldersbygd längs med en ådal i ett lokalt perspektiv

In this essay I have chosen to write about graves, settlements and historical, important central places during the late Iron Age and the introduction of Christianity in the east of Blekinge. The reason why I have chosen to write about this is because the area has many ancient monuments and not much have been written about the area. The main question is who where the people who lived there and why did they choose to settle there..

What traits make Swedish dairy cows survive?

The ability of dairy cows to survive and the economic importance of this have been in-creasing in dairy cattle breeding lately. Increased longevity contribute to an increased pro-portion of cows that produce milk in more productive lactations and reduces the replace-ment costs together with a good health and fertility. Unfortunately it is often argued that longevity has been decreasing due to a strong selection for production traits in dairy cattle.The aims of this study were to find correlations between different longevity evaluations and between different estimates on longevity and other traits in the Nordic Total Merit (NTM) breeding value. The aim was also to compare different traits for cows of two differ-ent longevity groups.The data were Predicted Breeding Values (PBV) from Nordic HOL and SR bulls and records from Holstein (HOL) and Swedish Red (SR) cows estimated by the Swedish Dairy Association.The three Swedish longevity indexes were very highly correlated (>0.89) and the corre-lations between the Swedish official longevity index and the five Nordic Cattle Genetic Evaluation (NAV) longevity indexes varied between 0.73-0.83.In the sire evaluation part, the traits most negatively correlated with longevity for HOL were dairyness, protein and fat index. In SR, milk, protein, and fat index only had slightly positive correlations with longevity.

Prestation i traktplanering

This study was an assignment for the company Holmen which is located in the region of Örnsköldsvik, Sweden. The study was focusing on the responsibilities of a forestry planner during the planning season. The study was investigating about how much time the planner spent in the office, in the car and out in the forest. Any other issues that would cause delays were also identified. To be more effective and to increase the number of objects to a district bank, a better preparation in the planning stage (for thinning?s or clear cuts) is needed as well as faster transition on to the next area.

En analys av centralkylan i Slakthusområdet i Stockholm

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

Konst som investering: En studie av investeringar i svenska kvalitetsmålningar under perioden 1985-2006

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation

The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.

Samband mellan BMI och kariesprevalens hos barn och ungdomar - en litteraturstudie

Övervikt och fetma hos barn och ungdomar har blivit allt mer förekommande och prevalensen ökar dramatiskt över hela världen. Sedan raffinerade kolhydrater introducerades har även kariessjukdomen fått större utbredning. Då det finns gemensamma bakomliggande faktorer som påverkar både vikt och kariesprevalens vill vi i vår litteraturstudie undersöka om det finns något samband mellan body mass index (BMI) och kariesprevalens för barn och ungdomar. Efter sökningar i den medicinska databasen PubMed på artiklar från de senaste 5 åren fann vi oeniga resultat med jämn fördelning. Resultatet av litteraturstudien är att två av de undersökta studierna tyder på att det inte finns något samband mellan BMI och kariesprevalens, lika många anser att det finns en svag eller möjlig association, medan två studier ansåg att det fanns ett signifikant samband.

Matregionen Södra Roslagen : en etnologisk studie om lokala beskrivningar av en regions mat

North of the city of Stockholm lies the area called Södra Roslagen composed of several municipalities. The purpose of this essay is to discover how local informants describe the food culture of the region and analyse why some types of food are mentioned and others are excluded. Several people within the food industry of Södra Roslagen were given surveys asking them to describe the food habits of the area, from commodities and certain dishes to traditions. These answers were analysed using the theories regional food, regiocentrism, revitalisation, placeless food and the idea of viewing culture through the long and the short perspective.One informant mentioned that professionals in the food industry of the region tend to follow trends from the rest of the world and another that many producers work with ecological requirements. Södra Roslagen was also defined by some as having a taste of summer as this coastal area sees an influx of visitors during that season.

Etiska Placeringar

Uppsatsens syfte är att jämföra risk och avkastning från en etisk fond med risk och avkastning från åtta slumpmässigt valda fonder och SIX RX-index för att utreda om etiska investeringar är jämförbara med andra investeringar. Skälet till att en egen etisk fond sätts samman är att vi ser problem med innehållet i etablerade etiska fonder.Genom att ställa upp finansiella och etiska kriterier har vi valt ut 34 bolag som ingår i vår egenkonstruerade etiska fond. För att uppfylla vårt syfte har vi valt att jämföra fondernas utveckling genom att studera fondernas avkastning, risk och sharpe-kvot under perioden 2002 - 2004.Inledningsvis placeras uppsatsen i ett teoriskt ramverk och den effektiva marknadens relevans för arbetet förklaras. Därefter följer en allmän diskussion om små placerares val och möjligheter i fråga om sparande. Utvärdering av fonder beskrivs därefter ingående och tre olika metoder att mäta en fonds prestation diskuteras.

Matematik, ett tråkigt ämne! Kan laborativt/praktiskt arbetssätt ändra elevers attityder till matematik?

The aim of the study was to investigate the students´ attitudes towards mathematics, their knowledge in the subject area they find the least interesting and whether laborative/practical working methods could awaken their interest and curiosity. During our work, we have looked into previous studies regarding girls´ and boys´ attitude and performance in mathematics. We handed out surveys to students in grade 9 at a School with many people from other cultures and nationalities in Malmö in order to find the answers to our questions. The result showed that most of the students thought that the subject area "scaling" was the least interesting. The implemented action program was a laborative/practical task within the "scaling" area.

Deltagardemokrati i de svenska kommunerna

The overall purpose of this essay is to study in which degree the democratic model that is called participant democracy works in the Swedish municipalities. To achieve what I set out to do I will focus on a central political area in which the Swedish municipalities has sovereignty versus the state, in other words in an area where they rule themselves. That political area will then represent how well the participant democracy works in the Swedish municipalities. The research questions then becomes:Does the participant democracy at Swedish Municipality level work in a satisfying way?Does the participant democracy in a large Swedish Municipality in a central political area work?Does the participant democracy in a small Swedish Municipality in a central political area work?Are there similarities and differences between the municipalities?If so, how can that be explained?To answer these questions I will study documents regarding the planning and building area.
