Högtrycket-Initierande undersökning av nytt limträmaterial
The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
Seroprevalence of Japanese encephalitis virus in pigs and dogs in the Mekong Delta
Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

Prefabricerat trähusbyggande med moduler : För- och nackdelar samt förslag på vidareutveckling
The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..
En studie kring migrationens betydelse för unga somaliers identitetsskapande i Bristol
The Somali community is relatively new in the UK and the majority of Somalis in Bristol are living under poor conditions in deprived areas. According to literature and research relevant for this study ethnic identity seems to be of more importance when threatened by environmental or social changes, such as experiences of migration. Young people are more exposed to such a process of identity construction. The aim for this study was to get a more profound understanding for the significance of migration for young Somali people?s identity formation in Bristol.
Risk för exponering av växtskyddsmedel i växthusmiljö
Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

En validitetsstudie på beeptestet : avseende maximal aerob kapacitet för elitishockeyspelare
Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.
Båtbottenfärger innehållande TBTO : huvudsaklig källa till TBT i miljön
Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).
