Utvärdering av flygbildstolkning för uppskattning av beståndsvariabler och åtgärdsförslag i ungskogar : en studie på Korsnäs Skog och Bergvik Skog AB i västra Dalarna
In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. Necessary information to get from the interpretation were silvicultural management suggestions, new stand delineation and new stand data. This thesis is supposed to evaluate the quality and usability of the interpreted data.
To evaluate the interpretation an objective control inventory was conducted in 60 stands, either through callipering or counting stems.

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.

Extrem-/äventyrssport innanför gymnasieskolans väggar
Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i
kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och
grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen.
Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra
olika gymnasieskolor i sydvästra Skåne.
I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem
lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det
var många faktorer som spelade in när lärarna beskrev varför de inte hade så många
lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser,
skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en
positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in
fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla,
ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt
viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya
aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit
ett stort fenomen i samhället.
Inverkan av flisig krossballast på betong
Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).
Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
Skredriskutsatta områden vid ett förändrat klimat - Konsekvenser för vattendistributionen i Göteborg
This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.
Optimering av B-stolpe
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
