The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

Denna undersökning omfattar kamerans inverkan på narrativet i visuella medium. Syftet är att få en insikt i hur kunskap om kameratekniker och ?vinklar påverkar hur åskådaren uppfattar vad regissören vill förmedla, och undvika att fokus sätts på element i filmscener som riskerar att förvirra åskådaren. För att undersöka detta problemområde har litteratur om filmhistoria och kamerateknik använts för att sammanfatta kunskap om hur kameran skall användas, för att förmedla relevant information och bygga upp den effekt som regissören strävar efter. Informationen utifrån detta har därefter tjänat som utgångspunkt för att skapa en kort animerad film med rymdtema där kameran eftersträvar att leverera en konkret visuell upplevelse där vinklar används för att understryka vad varje scen vill förmedla.

Pine twisting rust (Melampsora pinitorqua) is a parasitic rust fungus found all across Sweden causing damage resulting in lower quality and reduced tree growth in pine stands. In Sweden, the fungus is dependent on two alternate hosts; European aspen (Populus tremula) and Scots pine (Pinus sylvestris). Pine twisting rust has five different spore stages, two of them (uredinio- and teliospores) on the leaves of aspen. Injures on aspen caused by pine twisting rust is not extensive. On the other hand, when it infects the annual shoots of Scots pine it often results in a bent steam or even a top shoot breakage.

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.

This essay examines the limits of marketing strategies in the online casino industry, focusing on how data-driven and advanced marketing practices influence consumer behavior and contribute to problematic gambling consumption. By observing the online casino industry, the study identifies how companies use sophisticated data analysis methods and psychological techniques to attract and retain customers, raising significant ethical and social issues. The study highlights three key perspectives: the consumer's, the producer's, and the legislator's. From the consumer's perspective, it explores how various consumer behaviors, from responsible gambling to problematic overconsumption, are influenced by marketing and gaming experiences. This includes an analysis of how cognitive limitations and psychological biases can lead to irrational decisions and an increased risk of gambling addiction. From the producer's perspective, it examines how gambling companies use marketing strategies and technologies to increase profitability and what incentives they have to take social responsibility according to modern Corporate Social Responsibility (CSR) principles. It appears that companies do not see CSR as a business goal beyond the risk of current and future regulatory compliance requirements and policy changes. From the legislator's viewpoint, the current regulatory framework for the gambling industry is discussed, including the changes that occurred in 2019 when the special monopoly form we had in Sweden was transformed into a license market.

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

In this study we examine four Swedish newspapers? visual coverage of the Tunisian and Egyptian uprisings in 2010 and 2011 ? commonly known as the ?Arab Spring Revolution?, the ?Jasmine revolution? and in Sweden also the ?Women?s revolution? ? focusing on three main perspectives: news values and framing, postcolonialism, and gender.By means of a comprehensive content analysis and an in-depth semiotic analysis, the purpose of this study is to investigate how Swedish written media frames the revolution and its initiators and partakers through news photographs, headlines, lead paragraphs and photograph bylines, and to determine whether or not it reproduces earlier trends of media coverage and framing of non-Westerners and non-Western societies.The purpose of the extensive content analysis is to attain data for empirical research of the visual portrayal of the uprisings? first twelve weeks in Sweden?s four largest newspapers Dagens Nyheter, Svenska Dagbladet, Aftonbladet and Expressen. The analysis reveals that episodic framing is regularly used in all four newspapers, and that media demonizes Tunisians and Egyptians by constructing them as a brutal, uncivilized and threatening group which almost exclusively consists of men, and whose members are neither quoted nor named. It also shows that women are symbolically annihilated by media and that the very few women who do occur are gender stereotyped in accordance with established media conventions and postcolonial tradition, with the interesting exception of women being quoted to a larger extent than men. The analysis furthermore confirms the low occurrence of female journalists in Swedish foreign reporting, as well as demonstrates that the gender of the journalists does not influence what types of stories are written or how they are framed.The variable frequencies obtained from the content analysis provide indicators which are subsequently explored in the semiotic analysis of four news photographs.

The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms. One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

This essay examines teaching in source criticism in upper secondary school history education. Two questions are to be answered: 1. What are the conditions like for teaching source criticism? 2. What opportunities for further development in teaching source criticism are there? In order to set a standard for what knowledge and skills in source criticism the students need, I design a four step model for good source criticism based on the historical science.
