Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?
The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.
En simuleringsmiljö för distribuerad navigering
This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.
Solenergi i Norrra Djurgårdsstaden
This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.
Survival of the fittest?: Effekten av en varumärkeskris på konkurrerande svaga och starka varumärken inom en produktkategori
Almost every day newspapers cover companies and brands in crisis. This should worry companies as negative publicity has been shown to have a great influence on consumer perceptions on brands. In addition, brand crises have been shown to be contagious, meaning that they also affect consumers? views on other similar brands. This study aims to investigate spill-over effects of one brand crisis to another within a product category.
Kan risken för spontan contortaföryngring elimineras genom hyggesbränning? :
Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
Upprorsbekämpning i Anbar-provinsen
During 2004 to 2008, The United States Marine Corps (USMC) executed counterinsurgency operations in Anbar Province with the purpose to stabilize one of the most violent areas in Iraq. The Marine Corps successfully managed to suppress the insurgency as violence dropped dramatically in late 2007. What did the marines do in order to suppress the insurgency? Why did violence drop in the province? The Marine Corps approach and procedures have been examined earlier through theories of organizational learning and adaptation. However, there is an absence of studies aiming to analyse the Marine Corps? counterinsurgency approach through the analytical lens of counterinsurgency theory.
Hur kan studie- och yrkesvägledaruppdraget förstås?
The main purpose with this study was to investigate how study- and careers counselors active in primary school, secondary upper high as well as colleges describe regarding satisfaction of assignments and suggestions on their development. The study also included in what extent pure guidance tasks cover these assignments as well as what criteria affects these.Six study and careers counselors were interviewed during this study, all active in the three separate educational programs. Their responses regarding what tasks are included in their assignments as well as experiences are in line with previous research. The conclusion drawn from this study shows deviational results in-between the three educational programs, this regarding guidance tasks in their assignments. The conclusion strongly pinpoints that criteria as ?time? and ?need of guidance? affect to what extent guidance tasks fills these study and career counselors assignments..
K2-regelverket : En empirisk studie om varför företag inte väljer att tillämpa BFNAR 2008:1.
Purpose: The purpose with this empirical study is to investigate how many companies have chosen to apply the K2 framework and see why the remaining companies have chosen not to.Methodology: A choice of a quantitative approach has been applied to collect information and create a foundation for the problem. Furthermore a qualitative approach has been selected to cover the remains.Theoretical perspective: This section contains a presentation of the agency theory, the institutional theory, the k-project and a comparison of K2 and the existing regulation.Results: Three out of 143 companies applies BFNAR 2008:1. 13 out of 143 companies use self-generated intangible fixed assets. Out of 29 contacted companies only three know about K2.

Mjölkraskorsningar i avelsvärdering av tillväxt hos svenska köttrastjurar
The concerning issue of declining number of hunters in North America is also apparent in Europe and Sweden. When the bulk of research found on human dimensions and hunting participation has almost exclusively been done in the United States, this report seeks to add to the needed knowledge on a national level focusing on the causes of hunter declines related to social factors within Sweden. Using hunter data reaching from commune, county to National level, this report describes the correlation between a number of variables and the hunting participation in Sweden.The typical Swedish hunter lives in an area with low population density, the person usually has higher education, the living situation is stable with no recent moving and there is relatively good access to forest land. Persons with weaker connection to the Swedish culture such as foreign citizens, people with foreign background and people born outside ?the Nordic countries? are less likely to start hunt or participate in hunting.A strong relationship was found between the favorite game, moose (Alces alces), and the amount of hunters participating in the hunting.
Människans roll i skogslandskapets trädslagssammansättning, en studie i Ångermanland
Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.
Mätprocessen kring propelleraxlar
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
Hästägares kunskapsnivå och attityder angående hästutfodring
Horse owner?s knowledge about horse feeding and nutrition is directly linked to the horse?s health and welfare. According to several studies, both Swedish and foreign, horse owners generally have inadequate knowledge about horse feeding. The housing systems and feeding routines of today differs in many ways from what horses have adapted to through evolution. Wild horses live in harem herds and roam on large open fields, spending about 60 % of the day grazing, mainly grass and herbs.

The main aim of this bachelor thesis is to describe through a quantitative study the extent of support received by foster families, their opinion of the support and any areas that might need improvement. The foster families receive foster care support through a private agency. We concentrated on the following areas of support; education, health, contact with the children?s biological relatives and behavioral difficulties. These four areas have, in previous research, shown to be problematic for foster children.
Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The Role of Most Favoured Nation Treatment
Summary Title: Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The role of Most Favoured Nation treatmentAuthor: Andreas HelmerssonSupervisors: Cecilé Brokelind and Rikard LarssonProblem discussion and problem Formulation: The recent year?s rapid increase in foreign direct investment (FDI) is a clear indication of increasing globalisation. In order to stay competitive companies must take advantage of talented people, new technology and new markets around the world. Not only companies but also countries and regions, such as EU, need to take advantage of globalisation and the advantages that come with the increase in FDI around the world. Studies have shown that FDI does not only make companies more competitive but it also stimulates the economic growth of the region where the FDI takes place.
