In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

Bacillus anthracis is the causative agent of anthrax, a serious and globally distributed zoonosis affecting a wide range of wild and domestic animals, invariably also humans. However, although known to humans since biblical times, much remains to be elucidated concerning the ecology and transmission of this bacterium. Of particular interest is the Bacillus anthracis spore, the uptake of which is the predominant way to contract anthrax and which is legendary for its resilience in the environment and thus crucial for persistence and spread of the disease. Hence, the aim of this study is to review the natural transmission of Bacillus anthracis and investigate potential means by which soil persisting Bacillus anthracis spores reach concentrations sufficient to infect susceptible hosts. When reviewing the literature, three different theories can be distinguished. Firstly, ?the incubator area? hypothesis suggests that favourable soil factors, possibly in association with amoebas, may constitute an environment supporting repeated spore-bacterium-spore cycling, thus increasing the local amount of spores.

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

Acid sulphate soils is a wide spread problem along the northern coast of Sweden. This is causing great damage through low pH and leaching of metals out into the streams. These soils are estimated to be found in several places in Sweden but also in many other areas in the world. One of these areas in Sweden that are believed to contain these sediments is Mälardalen. The purpose of this study is to evaluate the extension of the acid sulphate soils in this area.

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

In our study, we investigated how the streamed TV domain relates to existing design principles for web design. Further, we have investigated whether there are specific characteristics of the domain that the design principles do not cover. In the survey we have studied two sites which are representative of the streamed TV domain. Finally, we discuss how applicable the design principles are for the domain and the specific characteristics that would require new or further developed design principles..

This thesis is about catastrophe tourism and the sustainability of the tourism in an environmental perspective. The purpose is to see if there is any interest for that kind of tourism and to see if the people who have an interest or curiosity of it thinks about the environment when they are traveling. A quantitative survey was made on the internet and people on Facebook, Resedagboken.se and Reseforum.se had the chance to answer it. There is an interest of catastrophe tourism and a few have been to catastrophe sites or would like to visit. The conclusion of the thesis is that there is a possibility of a sustainable catastrophe tourism because most of those who answered that they had or wanted to visit a catastrophe site also thought about the environment and cleaning up after themselves..

This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. The isotop data showed that import of Atlantic cod was significant in medeval Sweden. The analysis suggests that there is no specific time or event that the sites start to import cod but this varies from site to site. .

What gives a place meaning for it?s users? The intention of this paper is to investigate how landscape architecture is able to form places that evoke involvement from it?s users. Ideas within architectural theory such as territoriality space and place is being explained and used when analyzing several different case studies. The places for my case studies are all distinct in their expression and can all most be treated as objects on their own. In my case studies I came to the conclusion that a designer can work in many different ways to create a site that appeals to it's users, but that it is the sites that allow users to interact that become meaningful places..

This report investigates the possibility of developing a new and improved hip prosthesis. The result were five different materials that could be used for the prosthesis. These five solutions were Silicone Nitrate on Cobolt Chrome, phase stabilized Zirconium Oxide on Cobolt Chrome, Silicone Nitrate on Silicone Nitrate, DLC coated phase stabilized Zirconium Oxide and Chromium nitride coated Cobolt Chrome on Cobolt Chrome. In addition to this it was also investigated how to best market the prosthesis and how to transport them from production sites to hospitals..

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..

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.
