The purpose of my project was to explore variability. I wanted to combine different ways of sitting and create some kind of seating furniture that could be changed to fit different kinds of situations and needs. I sought after a way to express safety and stability in the seating furniture and at the same time make it clear that it could be changed into something else or something more. It was very important to me that the furniture piece would have a long lifetime and would be something you kept for a long period of time. I decided that the changeable factor in my piece would be the possibility to change it from being a chair for one person into being a bench for two people.

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.

Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

The purpose of this study is to find out the viability in performing final felling in stands with high timber volume or if it´s more profitable to leave these stands to the next owner. Will he or she pay more for the standing stock then the industry? The prices of forest-land have increased significantly over the last couple of years in Sweden and some properties seem to go higher than others. Is this because of higher standing stock volume or can a certain volume/hectare bring a higher price? Maybe a combination of both? This study is based on the the sale-statistics for 2012 from real-estate agency Areal.

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

Företaget TräEnergi Teknik AB säljer pelletskaminer. Försäljningen av produkten går inte så bra, men ägaren Carl-Axel Fagerström tycker att produkten borde vara efterfrågad av kunderna eftersom den är både miljövänlig och prisvärd. I denna rapport undersöks hur företaget kan ändra sina marknadsföringsstrategier för att nå ut till potentiella köpare. En enkätundersökning har gjorts hos återförsäljare för att ta reda på slutkundernas behov och önskemål. Ur undersökningen framgick att även om kunden är miljömedveten går priset alltid före.

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.

The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Reading spaceFurniture for reading for the new city library of GöteborgThe main purpose of my project has been to inspire people to read books at the library. I wanted to create something very site specific and chose a room on the second floor of the new city library to work with. To be able to relax, feel inspired and to concentrate on reading, the visitors of the library need to experience a sense of security. My solution to the different conditions or problems in the room and the needs I identified is a seat hanging inside a frame. When sitting down in the seat, the frame is low enough to see over but it is still experienced as a private spatiality.

Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.
