En jämförelse mellan fyra olika energisystemlösningar : För ett hus byggt efter passivhusstandard i Karlstad
AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes. The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

The government decided that on the 1st of May 2009 they would introduce a new kind of housing-form, condominiums. Ever since the new law came into force, no major changes have been done in the Swedish condominium market.
Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

"I världen, men icke av världen" : Konstruktionen av kristen manlighet i Skånes Missionssällskap ca 1939-1945
The aim of this study is to analyze the construction of "Christian masculinity" during the modern era. This is made in opposition to earlier research that has claimed that masculinity could not be constructed religiously, that is, without at the same time being constructed as effeminate or anti-masculine.Using a wide variety of theoretical concepts - such as discourse analysis, class, secularisation, masculinity as constructed from countertypes, and finally masculinity as a homosocial construction - I analyze a free church in Sweden, the Scanian Missionary Society (Skånes Missionssällskap), during the period of ca 1939-1945 (the society was a district of the Swedish Covenant Church, or Svenska Missionsförbundet), in order to argue for the standpoint that masculinity, in fact, could be constructed religiously. The primary source is the society's weekly journal Sydposten.The main results in this study can be summarized as follows: 1) The leading men in the Scanian Missionary Society did, in fact, construct a Christian masculinity, i. e. a masculinity whose core values and ideals were Christian, e.g.
CARABAS III Konstruktion av antenninstallation på helikopter
This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.
Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland
Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.
Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Bildens godkännandeprocessi katalogproduktion : The image approval processin a catalog production
The objective of this thesis has been to investigate the approval process for an image. This investigation has been carriedout at four catalog-producing companies and three companies working with repro or printing. The information wasgathered through interviews and surveys and later used for evaluation. The result of the evaluation has shown that allbusinesses are very good at technical aspects but also that the biggest problem they have is with the communication. Theconclusion is that businesses need a clear construction for the image process.

Industriell produktion av loggia - en studie om loggiarum som alternativ till inglasad balkong
AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..
Axial- och gradientkrympning hos golv på mark enligt Eurokod 2 : Sprickbredders beroende av betongkvalité, tvångseffekter och armeringshalt
AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

AbstractTitleOwnership apartments - The success that got lostDate of seminar2011-05-27Course/ProgramBachelor thesis/Construction and Real Estate Business ProgrammeAuthorsAnna ÅbergMarie Louise Homayon NejadMentorSven-Ola CarlssonExaminerGunnar WramsbyBackgroundThe 1st of May 2009 the government introduced a new accommodation form called ownership apartments. The government´s intensions were to give the individuals more influence in their housing, to increase the variety of accommodation and thereby create a freedom of choice when selecting their housing. They also saw opportunities to reduce segregation and increase the total production of houses and or apartments with this new type of ownership. The introduction was supposed to give the building companies a possibility to build with a new type of ownership and thereby create new and an increased number of projects for the future. This new accommodation form has however not gained the penetrating power that was expected.
Att lyckas som platschef i anläggningsbranschen
Att lyckas som platschef i anläggningsbranschenEva Karlsmyr Bygg- och anläggningsnäringen brottas med lägre produktivitetsutveckling än andra industribranscher och utveckling av ledarskapet ses ofta som en väg framåt. Kunskap saknas dock om vad effektivt ledarskap i denna specifika kontext är. Denna studie avser bidra med sådan kunskap genom att i en tematisk analys med kvalitativ ansats studera ledarskap ur effektiva platschefers perspektiv i ett svenskt rikstäckande anläggningsföretag. Utifrån meningskoncentrering av sju intervjuade platschefers berättelser har gemensamma aspekter av ledarskapet identifierats som respondenterna upplever avgörande för att lyckas i rollen. Studien har även undersökt hur dessa platschefer behöver påverkas av andra för att kunna utöva ett effektivt ledarskap.
