The aim of this study was to provide SCA Forest Norrbotten District with material to assist in their work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs. The purpose of this study was to find an available method to measure the occurrence of splits directly on incoming timber. The ambition was also to gain some knowledge about possible variations between different logging crews in terms of split frequency. If possible, this information could be used to investigate if certain crews produced more splits than others, and thereby making it possible to provide feedback to the logging machine operators. The study consisted of two major parts, a literature review, and a practical sawmill study.

Finnhamn is a group of islands that are located in the middle north part of Stockholm?s archipelagos. On the main island Stora Jolpan there is a camp called Sommargården, which consists of eleven different buildings in various sizes. The assignment given by the Archipelago foundation (Skärgårdsstiftelsen) is to analyze if it?s benefited to replace Sommargårdens current heating system that consists of electricity radiators, with a more energy efficient heating system. This research is done with help of the literature review and a visit to Finnhamn in order to map Sommargården?s current state and its energy usage.

One trend that can be seen in the EU countries is that employees want to exit from the workforce before they turn 60 years. A Dutch study of some EU countries has noticed that an early retirement from labor in many countries is considered as a social right. This has created an ?early exit-culture?. Large early outflows of the labor have created an institutionalization, the right to cease work early.

Modern forestry management may disadvantage some mykorrhiza forming fungi because; they are dependent on late successions and cannot survive the constantly recurring breaks in the continuity of their host tree. For this study the specie goliatmusseron (Tricholoma matsutake) was chosen to investigate this possibility. In Sweden T. matsutake is found in greatest amounts north of Örnsköldsvik on glacifluvial sandy soils in association with pine trees and reindeer lichens. Seventy two forest stands where the specie previously had been found were studied; 62 in the northern part of Sweden and ten in the southern. Several indicators were studied to find out if these stands have had a continuity of living trees.

Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

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.

Background and Problem: The lack of auditor independence is discussed being oneof the reasons to scandals such as Enron and HQ. A pricing strategy that has beendebated impairing auditor independence is low balling. To win a new client in atender process, audit firms supposedly offer an audit fee below cost and then increasethe fee the following years to recover the initial loss. The auditors? future financialinterest in the company due to the initial loss is by some believed to impair auditorindependence, which makes low balling in Sweden a relevant phenomenon to study.Aim of study: This thesis aims to explain if low balling exists on the Swedish auditmarket and if the size of companies affects the results of low balling.Methodology: To achieve the purpose of this thesis, a statistical study wasconducted.

Background: Vacuum assisted closure, VAC, is a method which can benefit wound closure. There are not many reliable studies about the effects of VAC in different types of wounds. Previous studies have shown that patients have experienced pain during dressing changes.Aim: The aim of the study was to survey in what kind of wounds the vascular surgery ward have been using VAC, to study the treatment process of VAC and how it has been documented and also to investigate if patients with VAC experienced pain during dressing changes.Method: The patients were chosen from a ledger, which contained 77 patients that had been treated with VAC on the vascular surgery ward. Data were collected with a journal survey protocol.Results: The result is based on 67 patients with a total of 79 wounds. VAC was shown to have a good effect on wound healing and infected surgical wounds were the most commonly wound category undergoing treatment with VAC.

AbstractTitle: It is not necessary to be the best, but I don?t want to be average Author: Maja Benca & Emma Ender Tutor: Hedvig EkerwaldPurpose: The purpose of this thesis was to identify the subjective experiences of stressors and demands of law students of Uppsala University. Beyond these problems, this thesis was also identifying if there was a balance or conflict between social life and studies from a social psychological perspective. This essay is based on five key questions: How does the subjective experience of stress and demands affect the interviewed law students? How do the interviewed law students handle the stress and demands in their studies and in everyday life? Do the interviewed law students consider there is a balance between social life and studies? How do the law students want to present themselves in front of classmates and teachers? What do the interviewed law students consider to be the main goal in life? Method/Material: The material used in this thesis consists of a total of ten interviews with law students of Uppsala University, five women and five men in the ages of 20 - 32.

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate deciduous forest.
