The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..

The purpose of this essay is to investigate the melancholic, poetic language in Bübins unge (Bübin´s brat) by Mare Kandre (1962 ? 2005). In my opinion the novel, which is about a teenage ritual, also gives an imaginary arena for archaic and unmentionable experiences of the libido. It is therefore a witness to the truth of the subjects complex mind. To my assistance I have Julia Kristeva´s theory on the abjection, the successful melancholia and her concepts of the outsider and the catharsis.

This paper deals with variations in the osteological material of dog (Canis familiaris L.) from the Mesolithic Scania, southern Sweden. The general aim is to discuss the use and specialisation of dog during the period, and differences or relations between cultures and traditions within the Mesolithic period. The study is based on a analysis of the bone material from the sites; Ageröd I:A-D, Ageröd I:H-C, Bredasten, Bökeberg III, Hög, Löddesborg, Ringsjöholm, Segebro, Sjöholmen, Skateholm I-II and Tågerup, phase 1-3, with datings from Late Maglemose Culture to Early Ertebølle Culture. The seminar paper also includes descriptive statistics of the osteometrical data of Denmark, from several studies of Degerbøhl (1927) and Noe-Nygaard (1995, 2003). The study is focused on the relation between size, robusticity, muscle grooves and ligaments of mandibula, tibia, radius, humerus, femur and metacarpalia/metatarsalia.

This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodineand strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflifeof about 30 years and is therefore one of few radio-fission products remaining inmeasurable quantities in the Swedish soil. Radiocaesium behaves similarly to potassium insoil-plant systems and is easily absorbed by plants. It is important to understand how 137Csbehaves in different ecosystems in order to minimize the risk toward humans.The aim of this study was to determine how potassium fertilization influences radiocaesiumcontent in different forest plants and fungi. Potassium fertilizer was spread once in 1992 withapproximately 200 kg KCl per ha.

Den här studien har genomförts för att undersöka hur en gitarrlektion fungerar över internet och hur den upplevs av dess användare. Undersökningen har genomförts genom att jag och två av mina gitarrelever har utforskat två olika gitarrhemsidor. Vi har tagit lektioner från dessa sidor. Där visas materialet genom video, ljud och med eller utan tabulatur. Därefter har mina elever intervjuats där de bland annat har fått svara på frågor om vad de tyckte om hemsidan, lektionen och lärarens kvalitet och hur det kändes att inte ha en lärare närvarande vid lektionstillfället.

This thesis deals with the possibilities of installing solar panels on a property, the building is owned by Kornhillschurch and called Kornhill. The owners of the property wanted to learn more about potentials for installation of solar panels on the property, therefore we described different types of solar cells and solar cells essential function to generate electricity in the report. Different factors that are limiting the generated energy are mentioned.An investigation of the property?s potential has been made in order to consider different designs. When sites that were considered suitable for solar cells were selected, different design options were made, one for each site.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

When building large buildings, such as compartment buildings, there is a number of deliveries arriving on the construction site daily. In order to receive these deliveries without disturbing the rest of the work going on JM often books a fixed unloading time. When doing that they can be prepared when the delivery arrives. Making sure there is a suitable unloading area, someone to meet the delivery and when needed proper machines, such as a tractor or a crane, to help unload bigger deliveries. The person receiving the delivery is supposed to make an acceptance control where they check the delivered goods making sure nothing has been damaged in transport and that they have received what they were supposed to receive.

The aim with this thesis is to investigate two different methods used to test usability on web-sites to determine the advantages and disadvantages of two methods and compare the results. The two selected methods are the think aloud method and asynchronous remote method. Re-mote usability testing has existed for more than ten years but the possibilities with this meth-od needs to be explored more.To achieve the purpose of this thesis a case study was conducted on an e-commerce site and for the online remote usability testing software was used.The results of this study show that think aloud usability testing encounter more issues with the website than the remote usability testing..

The Pitted ware dwelling site Ajvide on the west coast of Gotland in the Baltic Sea is, because of its long continuity from the late Mesolithic to the middle of the Scandinavian Bronze Age, an interesting research object concerning Stone Age in the Baltic area. In this essay, a comparison between two activity areas on Ajvide have been carried out in the purpose of finding out what these areas may have been used for during the middle Neolithic.  It has been showed, through zooarchaeological analyses of animal bones, that the areas most likely are depositing sites for slaughters refuse and food debris. If it is a result of everyday or more ceremonial activities is left undetermined..

This thesis has had its focus on ceramic shards found in a trench by the late neolithic western shore of the Ajvide site. The purpose of the thesis is to investigate if there are changes in the pottery between the test trench and the ceramics found by the graves, known as the main site. The author has compared the ornaments from the test trench with an ornament schedule made from over 50 000 shards from the assumed main site. Not only changes regarding ornaments has been noticed but also new techniques and raw material. The author has also implemented two 14C datings which backs his hypothesis that the shards from the test trench are younger than the shards that made the earlier ornament schedule.

Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution. This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.
