This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder. Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.

Inledning: Såväl politiker, som media och många andra kritiserar undervisningen av svenska för invandrare (SFI) kraftigt, det diskuteras att invandrarna inte lär sig svenska i önskvärd omfattning och integrationen av de nyinkomna går dåligt. Studien har därför velat undersöka dessa frågor SFI-deltagarnas syn på andraspråksinlärning och deras integration.Syfte: Studien avser att undersöka vad SFI-deltagare anser om SFI:s medverkan till integration och andraspråksinlärning i det svenska samhället.Forskningsfrågor: 1. Vilka diskurser framträder i SFI-deltagarnas konstruktioner av vi och de andra?2. Vad är SFI-deltagarnas syn på SFI:s medverkan till deras integration i samhället?3. Hur har SFI konkret bidragit till SFI-deltagarnas integration, avseende t ex arbete, vänner, kontakter, studieframgång, boende och skola?Metod: Diskursanalys enligt diskurspsykologisk metod.Teori: Den här studien har sin teoretiska förankring i socialkonstruktionism med influenser av postkolonial teori och kritisk teori.Resultat: Antagandet var att bristande språkkunskaper skapar segregation och omvänt, vilket besannades. Sammanfattningsvis kan sägas att informanterna uttryckte en massiv kritik av SFI:s förmåga att hjälpa dem med integrationen och att de även var kritiska mot praktik och arbete och mot den språkträning som de då fick. Men de är inte enbart kritiska till SFI-undervisningen, de ser även positiva effekter av undervisningen.

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

The interactive whiteboard (IWB) is to be found in many classrooms in Sweden, and its number is growing rapidly. There is a lack of research of the use of the IWB in Sweden. The Swedish National Agency for Education refers to English research where the investment in the IWB in school is huge. In this study I will investigate how the IWB can be used as a mediating tool in the learning process. My study examines how interaction pattern appears when the teacher teaches with the IWB as a tool.

Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.

Facebook has over 665 million users worldwide and has created a new venue for companies to interact with their stakeholders. However, since it is a new phenomenon it brings some uncertainty and confusion as how to manage the communication on Facebook, and it is only recently that research and literature has become available on this topic.The purpose of this study is to investigate how three chosen companies within the travel industry communicate on Facebook. We also compare the results to the existing literature to see how they can improve from a theoretical point of view. We thereby hope to shed a light on, and add knowledge to, a research area where we have identified weaknesses. In order to fulfill our purpose, we used a quantitative content analysis as well as qualitative interviews.The major findings in our study on Facebook communication include a lack of strategy and target audience awareness, as well as a self-centered communication.

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

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.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

This paper shortly describes the coronavirus family, bovine corona viruses (BCV) properties and two diseases that BCV causes, winter dysentery and calf diarrhoea. The purpose of the study was to compare different diagnostic methods to detect BCV. Different methods are discussed, PCR, ELISA, immunofluorescense and virus isolation. Investigations were made in three different herds with winter dysentery; one dairy cattle farm with about 100 cows of different ages, one testing station for bulls with about 150 bulls and another small dairy cattle farm with 26 cows and 20 replacement heifers and calves. Faeces and nasal swabs were analysed with PCR and ELISA. The result shows that PCR seems to be a reliable method for detecting BCV but that the ELISA test can not be used as a reliable diagnostic method to analyse samples from animals with winter dysentery..

Due to historically low prices for electricity in Sweden, many small-scale hydropowerplants were closed down. A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Abstract: Since the recession caught the market in fall 2008, multiple companies have suffered due to their former aggressive investment behavior. Huge goodwill piles have been collected ready to be doomed by the market. The aim of the study is to investigate equity analysts? consideration of goodwill in a recession market. An empirical study is conducted, based on interviews with ten Swedish equity analysts that follow companies with relevant goodwill status.

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.
