År 2001 upptäcktes askskottsjukan i Sverige för första gången efter att den härjat i Polen och Litauen sedan mitten på 1990-talet. Syftet med det här examensarbetet är att, med utgångspunkt utifrån att asken, Fraxinus, kan vara hotad på grund av askskottsjukan, hitta ersättande träd för utemiljöer, med fokus på biologiska, funktionella och estetiska aspekter. Askskottsjukan tros orsakas av den nybeskrivna svamparten Chalara fraxinea. Svampens biologi är fortfarande okänd, vilket gör att man inte med säkerhet vet om den ensam orsakar askskottsjukan. Symptomen som sjukdomen ger är döda skott, vissnande blad och kräftsår på stammen.

This thesis work aims to describe the prerequisites for a distributed treatment platform for real-time sharing of rounds performed by paediatric oncologists. The work started during the autumn 2004 and is directly aimed at improving the situation for the thirty or so specialist treating children with cancer. The work is not limited to the description of such a platform but also to select suitable software and hardware for the implementation of the platform and further more to coordinate the implementation. The production of several documents describing the platform is also part of this work. The work successfully led to the implementation of such a platform as described in the published article Barnradioterapi på distans Kristenssen et.

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

AbstractThis act is about how five children with dyslexia consider and understands their diagnosis. It is also about their self-image, future sights and about how their school life is compared with before they got their diagnosis. The study is implemented autumn 2011 on a medium-sized school in central Sweden. The survey was implemented through interviews with the five children, of which four was girls and one was a boy. The study shows that the children understand their dyslexia relatively well, but that they experience that it is bothersome to live with dyslexia.

The study took place at a food corporation in Växjö, Sweden. It describes a building that contains four tanks in which glucose syrup is stored. The purpose of the study was to calculate the amount of heat that leaves the building and the amount of heat that is supplied by the installed heating equipment. Before the calculations could be implemented, all the systems that supply the building with heat had to be examined. With a small amount of information from earlier studies, the work to gather all the data necessary for the calculations began.

With a base in Ian Manners? theory about Normative Power Europe ? that the European Union is to be seen as a normative power instead of a civilian or military ? this paper seeks to contribute to the discussion about identity by examine the normative elements of the union?s policies towards Russia between 1997 and 2013. Which norms are most important and how does the diffusion look? The findings show that democracy, rule of law and respect of human rights are among the most diffused norms, and this is more than often done by using the Russian interest in economic progress. Over time the European Union has taken on a more critical approach against Russia, while still appreciating their prosperous relation when it comes to trade and energy.

Studies on wild boars have shown that piglets at 10 to 12 days of age can be introduced to pigs outside the litter without fighting. In today's production systems, the litters are kept in separate pens until weaning. At that point, the litter is divided and the piglets are placed together with piglets from other litters. This usually leads to aggressions among the piglets and may cause stress. This literature review aims to find out how piglets perceive other pigs in their surroundings.

The aim of this study was to give an insight of the construction of girls in their relationships with friends and lovers in the Swedish magazine Julia. The magazine turns to girls of age nine to fourteen. The research questions were 1) What is the construction of the girls in their relationships with friends and lovers about in Julia? 2) How are girls constructed in their relationships with friends and lovers? Three issues of the magazine from the winter of 2014 were selected as material for the study. Critical discourse analysis (Fairclough, 1992, 2010) was the point of departure in the analysis.

A frequently asked question in real estate marketing is at what time of the year it is optimal to invest or sell. The aim of the project was to answer this question and to generate a prediction model over real estate located in the centre of Stockholm that takes seasons into account. With acquired sales statistics in Stockholm between 2010 and 2013 it was possible to perform a linear least square regression, also known as Ordinary Least Square (OLS), with describing qualities and season of sale as parameters. Statistical problems such as Multicollinearity and Heteroskedasticity have been taken into account when deriving the model. The result was a highly accurate prediction model indicating the profitability of investing in real estate during the summer and selling during the autumn..

This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

AbstractThe subject of this paper is children?s thoughts and feelings about the forest and on the importance of the schools for their students? thoughts. The aim of this paper is to find out if there are any attitude differences towards the forest in schools in the city and in the countryside. To fulfil this purpose the work has been divided into two questions,1 Do children have different thoughts about the forest, depending on where they live?2 Does the school affect their students? thoughts about the forest?Two schools with different locations in the country have been visited.

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

The thesis addresses the issue of when a bankruptcy estate, under environmental law, is responsible for the debtor?s environmentally hazardous activities. A fundamental principle of insolvency law is that the bankruptcy estate is not responsible for the debtor?s prior obligations. The environmental legal rules do not distinguish whether an injunction liability is directed against a bankruptcy estate or another operator.
