Epiphytic lichens associated with different traffic intensities along the highway E4

Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.

Egna märkesvaror i dagligvaruhandeln : - En studie om hur egna märkesvaror påverkar konsumentens impulsköp

The thesis concerns itself with studying the effects private brands has on the consumer?s impulse buying in the grocery industry, as in degree of unplanned spending and the selection process between manufacturer brands and private brands when such a purchase is performed. The study?s methodology is characterised by a qualitative approach, whereby the study acknowledges the inductive approach towards the empirical setting even though the Mehrabian-Russell model along with motivational theories serve as highlighters of relevant aspects in the empirical field. The study concludes that both the utilitarian and the hedonic consumer decide what to buy before entering the store, whereby a low degree of needs arise in the store.

Bildbaserad rendering : Implementation och ja?mfo?relse av tva? algoritmer

Det här arbetet har gått ut på att jämföra två algoritmer för bildbaserad rendering. Båda algoritmerna använder två bilder som spelats in med formatet MultiView plus depth för att rendera nya mellanliggande vyer av en tredimensionell scen. De tvådimensionella bilderna är kompletterade med djupvärden för varje bildpunkt. Renderingen kan då utföras genom perspektivriktiga transformationer där alla bildpunkters nya positioner projiceras individuellt. I samband med renderingen behöver bland annat mätfel i de ursprungliga bilderna samt skymda partier hanteras.

3-D handlingar, GPS-styrning och VA-moduler- En ny metod för framtida anläggningsprojekt

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

Resultatet från studien visade att variablerna, feedback från frivilligledaren, Röda Korsets utbildningar och volontärers trauman relaterade starkast till arbetstillfredsställelse.

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Consumers? Perceptions of Variety ? the Impact of Private Brands

This study aims to investigate how consumers perceive variety in grocery stores and further how private brands have affected consumers? perceptions of variety in grocery stores.The study focuses on the perceptions and attitudes towards variety and the impact of private brands on perceived variety. Hence, a qualitative rather than quantitative study has been used. Photo elicitation has been used in both focus groups and in-depth interviews, which have been the empirical data collection of the study. Scientific articles and books have also been used in the process.

Vattensänkningar : en analys av orsaker och effekter

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Granföryngring på tallmark, hur ofta förekommer det? :

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.

Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

Moder Jord i kyrkorummet? : En undersökning av kopplingarna mellan det kristna och det fornnordiska i Vester Egede kyrkans dopfunt som objekt och vad angår motivval, tolkning och dopritual.

A church in rural Vester Egede from the earliest Christian period in Denmark e.g. the early 1100, a baptismal font is found showing a woman breastfeeding two animals. She is said to be a typical early roman Luxuria, in mild appearance. However, what makes her unique is that she appears standing on the top of her head, her womb serving as font. The main question is how come that a baptismal font like this is to be found in a church, leading to the sub question, if this font really has a Christian origin or could it be rooted in Norse, pre-Christian tradition, alternatively is the font an expression of a syncretism between the two colliding cultures.
