"Jens Holgerß af Glimynge" Om en borgbyggares intentioner
Glimmingehus is one of the most well preserved medieval castles in Sweden. This essay examines why it was built ? what were the intentions of the Lord, Jens Holgersen? Even though we?ll never be able to ask him, the answer to the question ?why?? can give us aninsight of how a man of his position thought in the Late Medieval time. To answer the question the castle are explored through three different angles ? the Lord of the castle and thesocial context the castle was built in, the landscape surrounding Glimmingehus ? has Jens Holgersen left any structural clues there, and finally the castle itself ? how has a potential visitor experienced Glimmingehus? The methods are greatly influenced by Gunhild Eriksdotter, who in her book Bakom fasaderna explores the possibilities of an analysis ofexperience together with an analysis of function in the archaeology of buildings.
Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige
Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
Hårdgörning av Asp
Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en treskiktskonstruktion som motverkar träets fuktrörelser. Dessa skivor har dock visat sig vara instabila och tidigare försök har uppvisat deformationer i form av kupning. Denna undersökning syftar till att utreda förutsättningarna för att använda komprimerad asp samt att ta fram underlag för framtagning av en kommersiell produkt.Praktiska tester har genomförts för att studera hårdhet, återfjädring och densitet hos det komprimerade virket.

Miljökvalitetsmålet God bebyggd miljö i Jämtlands län : En studie om hur miljökvalitetsmålet ska kunna uppfyllas till 2020
The aim of this study was to investigate and analyze what is required for the environmental quality objective Good built environment to be fulfilled by 2020 in the Swedish county Jämtland. The focus of the study was to gain an understanding of the work that the local government does and further investigate the problems that the officials face with implement these questions in themunicipal planning.The study is based on semi structured interviews with officials in the municipalities of Jämtland county. General plan and programs for the municipality have been reviewed, based on how the plans highlights these issues linked to sustainability and Good built environment.The results of the study show that there are major problems with the formulations of the environmental quality goal in itself and its specifications. The environmental quality goal is formulated to suit the entire Sweden. But as it turns out in the analysis it does not work on the basis of the conditions inJämtland with sparsely populated areas and scattered dwellings.
En ?terinventering och analys av den svenska populationen av svart nervmossa (Campylopus atrovirens)
Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.
Investering i spannmålstorkning och lagring på gårdsnivå : en jämförelse av ett silotorksystem med omrörare och en konventionell anläggning
The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season.
An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.
Barns språksvårigheter : Hur man som pedagog bemöter barn med språksvårigheter
The main purpose with this study was to get an insight in how to best be able to help children with language difficulties, and learn to see those who are in need of extra help and attention.The study is the result of three separate interviews with a speech therapist, a preschool teacher, and a teacher for children with special needs. The other information that my study is built on comes from books.The answers that I got from the interviews questions, have I built my discussions from.Since I only have done three interviews, can´t I do any general conclusions, from my findings.The answers that I got shows that it`s not always the same answers from the speech therapist, preschool teacher and the teacher for children with special needs, are the same. But most of the answers had a similar conclusion. The most important finding in my study, which also the literature agrees with, is that. It´s always important to read out loud to the children.Keywords: language difficulties, exertion, learning to speech and communication..
Kv. Tvättstugan, ett flerbostadshus med massiv trästomme : Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter
Title: Kvarteret Tvättstugan, an apartment building with massive wood construction. A thesis about acoustic and fire requirements and a comparison of energy and moisture aspects. Earlier restrictions in the Swedish legislation have resulted that only a small percentage of the apartment buildings that have been built are designed with a massive wood construction. It has been allowed to build unrestricted with wood since 1994 as long as the function of requirements are fulfilled. This change in the rules together with the great environmental benefits of wood has led to that more companies choose to build apartment buildings with wood. One of these companies is Folkhem Production AB.
Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme
The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.
Moderna kyrkor. Reflektioner kring ett övertaligt kulturarv
Churches are seen as one of Sweden's most valuable cultural heritage. They bear witness to a living tradition and gives us knowledge of society at large and therefore people's lives at different times. These buildings possesses a high value, which is shared by the vast majority, and they are protected by law. The concept of modern churches is in this essay the churches built after 1940, which is not covered by law. The older churches has therefore a cultural and historical value which the modern churches lack.About 600 churches are built after the year of 1940 and the total number of churches in the country is 3400.
Stenebergs sockerbruk: en fallstudie av en timmerstomme fr?n 1739
Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in
1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood.
Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there
exists today a surprisingly low amount of documentation of the building itself. In order to
enhance the existing and lacking building documentation, this case study aims to shed light
on the building's log-timber built frame, focusing on how it was constructed, how the long
lengths of its walls were handled and what type of joinery and tools were used.
A thorough investigation of the building is conducted on site, followed by gathering of
information which is then presented through text and illustrations. The findings indicate the
orientation of timbers, location of joints and scarfs as well as tool marks which together
contribute to the forming of a basis of understanding of the building's construction..
