Brown bear (Ursus arctos) den site concealment in relation to human activity in Scandinavia

As a hibernating species, the brown bear spend most of the winter months in a den as astrategy to avoid unfavorable conditions. The denning period is a vulnerable time for bears,making them unable to flee disturbances without losing valuable amounts of energy. Brownbears' wariness of humans and avoidance of anthropogenic disturbance often steer denningbears away from human infrastructure, and bears thereby avoid possible disturbance and itsassociated energetic costs. This study was carried out to test the hypothesis that bearsdenning closer to infrastructure select more covered den sites to compensate for the closedistance. Dens from 32 individuals were visited and analyzed in terms of sighting distance(a measurement for den horizontal cover) and habitat ruggedness, in relation to distances toinfrastructure.

Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Didaktiska arter

The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.

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.

Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog

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.

Lämpliga områden för vindkraftsetablering på land i Norrbottens län

Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

Assistansrobot "Slangaren"

This project is a step towards automatic firefighting. The goal is to decrease the number of personal injuries by replacing the human firefighter with robots or similar technical tools. Especially in very hostile environments due to risk of explosions or building collapse. A robot is easy to replace and can be maneuvered from a safe distance. The idea of the project comes from the company Drones Networking which aims for developing a totally autonomous firefighting system.

The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

Konstruktion av tvåhjulig balanserande robot

Att ta på allvar? Om självmedvetenhet hos Bob Hansson

Based on Theodor W. Adorno's theories about the relation between society and lyrics, and critical theories about postmodernism, it can be seen in Bob Hansson's lyrics how he tries on the one hand to write in a modernistic tradition but, on the other, is very influenced by postmodernism which results in a conspicuous self-distance and self-contempt..

Stadskampen om kunderna ? En studie om värdeskapande i handelsplatser

AbstractThe purpose of this study is to investigate how value creation influences consumers´ choice of market place. We have chosen to focus on how inner city centers can compete with external shopping malls by examining what values consumers find essential in shopping areas. The development within the retail market with more external malls outside cities has resulted in impoverished city centers; therefore, new strategies towards more attractive servicescapes in the inner city are crucial. The study is based on a qualitative approach due to deeper understanding and closeness to the subject, where Kalmar city is chosen as a case. We have completed a focus group study where respondents from each target group where represented.
