Gotlands solelpotential

The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).

Tillgänglig teater? : Uppsats om arbetet med och den fysiska tillgängligheten på Wermland Operaoch Västanå Teater

This bachelor thesis is based on how the two cultural institutions in Sweden have been working onincreasing physical accessibility. Based on the three objectives specified by the Swedish Kulturrådet(Swedish Arts Council). These points are 1.forming a workplace strategy, 2. Work to remove simpleobstacles in buildings and 3.Improved Web access in regard to the accessibility for physically disabled.The work regarding the accessibility goals is set on the time frame 2011-2016. The institutions studiedin this paper are Wermland Opera and Västanå Teater and how the two institutions have worked toimplement the three objectives and how the discussion about the accessibility within the two theaters hasbeen organized.The method of information gathering in this paper has been interviews with representatives from the twotheaters.

Experimentell undersökning av provkroppar för trälimfogar

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

TOMO Hugglink

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Förbränning av pellets framställda av defibrerad granråvara :

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

Alla vill beta men ingen vill bränna : skogshistoria inom Särna-Idre besparingsskog i nordvästra Dalarna

In this work I have tried to reconstruct the forest history within Särna-Idre forest common in northern Dalarna from the 19th century until present time. The Särna-Idre region has been an extensively used landscape for a long time. Pollen which indicates grazing has been found in samples orginating from the 10th century. Early travellers from the 18th and 19th centuries seem to have been passing trough a "used" landscape. Burned forests on naked ground are described as common. Also large areas are mentioned as undisturbed with lots of large trees, snags and dead wood.

Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Vilka är dagens krav på gårdsverkstaden? :

After been told that an ordinary winter service for our combine should cost more than 20000 SEK, not included spare parts, I decided to write this paper about today?s requirement of the workshop on a farm. I think that the lack of proper premises is the reason way not more of the ordinary machinery maintenance or upkeep is performed on the farm. When I did my literature survey I found that the Swedish environmental code, set by the Swedish law regulate how drain or sewer should be built. The environmental code however leaves a lot for your own interpretation. It might not be so bad but it must be very hard for the local environmental office to interpretation the regulations, since they are the ones that gives permission for the sewer in your workshop.

Edward Scissorhands : En genusanalys

Syftet med denna uppsats är att analysera mansbilden av karaktären Edward i filmen Edward Scissorhands (Tim Burton, 1990). Genom attstudera hans personlighet och egenskaper ur olika perspektiv, som kan uppfattas som både manligt och kvinnligt, har jag försökt att ta reda på vem denna utstickande karaktär är.Med hjälp av genusteorier och jämförelser av tidigare filmatiseringar som Ed Wood (Tim Burton, 1994), Sleepy Hollow (Tim Burton, 1999) och The cabinet of Dr. Caligari (Robert Weine, 1920) har jag även kunnat fördjupa mig i mansbilden av Edward. Jag har dessutom fokuserat kring Tim Burtons säregna filmskapande, men också kring stjärnskapet hos Johnny Depp, skådespelaren som Burton ofta samarbetar med.Edward Scissorhands har visat sig vara en man med både manliga och kvinnliga attribut, vilket gör honom till en icke stereotypisk man som saknar hjältemod och en muskulös kropp. Trots det så tyder inget på att han är mindre man bara för att han har mer eller mindre egenskaper som generellt uppfattas som manliga.

Fiberföstärkning av Limträbalkar

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

Älgens barkgnag på granstammar : omfattning med avseende på geografisk utbredning, skadad volym och ekonomiska konsekvenser

In three areas in the province of Småland studies has been done to investigate how big damage the moose may do to P. abies. An inquiry examination and two different types of surveys were done to find out how big area, which volume and which financial consequences the moose debarking has had on the forest. When the volume was calculated the rot spreading was included. The area that was damaged was stipulated with the answers from the inquiry examination. 59 % of the asked forest owners answered the inquiry.

Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås

Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.

En kostnadsanalys av energieffektiva flerbostadshus

In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.
