The aims of the silvicultural method natural regeneration of spruce (Picea abies L. Karst) in birch (Betula pendula and pubescens) shelterwoods are to establish a new stand of tree seedl-ings and to protect those from high groundwater levels, frost damages and grass competition during its first life years. The aim of this work has been to (i) describe how shelterwood and stand characteristics influ-ence the results from using natural regeneration of spruce protected by a shelterwood of birch, and to (ii) compare those regeneration results with planting of spruce after soil scarification in clear-cut areas. Totally 17 harvesting sites have been inventoried and 15 of those included natural regenera-tion in birch shelterwoods, and two were subjects to soil scarification and planting of spruce. The sites represented 7-10 year old final cuts and are located in the coastal (eastern) region of the province of Norrbotten in Sweden. In all areas shelterwood and stand characteristics, as well as the number of main crop seedlings and the height of the highest main crop spruce seedling, were estimated and registered in all areas.

The purpose of this investigation is to show how politicians state primary goals and how they break them down into secondary objectives within the sector of Child-and education area. This is supposed to create a general image on how the targeting process is handled within the public activity. Finally, this will lead us to what is necessary for the targeting process to work successfully within the public activity.  We have implemented a qualitative study within the two chosen municipalities. This case study is based on personal interviews that are conducted through semi structured questions.

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

The study aims to demonstrate the significance of educators lived experiences of stimulating children's physical development. It has been noted that children are occupying themselves with more and more sedentary activities, which may lead to that they do not develop motor skills at the pace expected. To understand educators lived experiences from a phenomenological hermeneutic perspective empirical relevance has been collected through narrative interviews. The results shows that educators find it difficult to understand the Curriculum goals for motor activity and that the desire to stimulate motor development is great, but the realization is conspicuous by its absence. The discussion highlights educator?s commitment and motivation and the importance of being a reflecting practitioner..

The aim of this essay is to examine the view on children with disability´s in the end of the 19 Th to the beginning of the 20 Th. We will examine the children that lived in Eugeniahememt but we will also examnie the view the society had on the children who lived on Egueniahemmet. In our essay there are four questions that we are going to answer.- Who took the initive to start Eugeniahemmet and how did it affect the activity?- Which view had the society on the children who lived on Eugeniahemmet?- How did the work with the children look like?- Which view had the staff, in Eugeniahemmet, on the children?The method that is being used in this essay is trying to analyses what the material tells us about the view on the children and how the work with the children lookt liked in Eugeniahemmet.The theory that we use is about Michel Focaults look on madness. Focault says that a person who is mad dosen?t have a connection between body and soul and that creates hallucinations witch leeds to madness.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

AimThe purpose of this study has been to examine attitudes towards dance in a broad sense, among Swedish schoolchildren. The study has been done with three different questions in mind: What do pupils think and express about dance? Are there any differences in attitude towards dance between girls and boys? And how do the pupils relate to gender conceptions in connection to dance illustrations?MethodEight pupils 12 ? 14 years of age have been interviewed separately during physical education lessons. During parts of the interviews dance illustrations were used in order to encourage the pupils in their discussions, especially when asked to relate to dance and gender conceptions. The statements have been interpreted from a gender theoretical perspective.ResultsMy interview study shows that male pupils to a larger extent than female pupils inhabit hostile feelings towards dance as part of physical education lessons.

Sweden has a long and extensive wind band tradition. Today the interest for the traditional instruments is decreasing among children and teenagers. What can this be due to? Which conditions are needed for a functional wind band in the future? The purpose of this essay is to find answers to these questions and at the same time shed light on good examples, where the wind band activity works. To be able to answer the questions have I made four interviews with persons who have a big knowledge and interest about the subject.

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
