Socialt och emotionellt lärande i grundskolan - hinder och möjligheter vid implementering
Social and emotional learning is getting more and more common to work with in Swedish schools today. That has made it more actual to do studies of how you best can implement a method in health prevention and promotion in schools and how you do for to keep the work sustainable. There are some American studies that describe implementation of methods in schools and a few studies that describe implementation of methods for social and emotional learning in schools. It is important to see implementation as a process and not as an individual event. The process never end but continues as a cycle in three phases; readiness phase, planning phase and implementation phase.The aim of this study was to describe teachers and principals experiences of obstacles and possibilities at implementation of an evidence based program for social an emotional learning in compulsory school as a part of the schools health promotion activities.
Statistisk behandlig av driftsdata : Ur Garpenberggruvans driftcentral
Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.
Common misconceptions about everyday astronomy-related phenomena among students in the 9th grade
Students of all ages host a wide variety of scientifically inaccurate ideas and conceptions about everyday astronomical phenomena, such as the seasons, the moon phases, and gravity. The field of Astronomy Education Research has over the last decade experienced an accelerating growth, although the majority of studies have been conducted in the USA. In this work, the 9th grade students of a typical Swedish school were surveyed by means of a questionnaire in order to probe their conceptual understanding of several key concepts in astronomy. In the end, the number of respondents amassed to a total of 90. The results were analyzed with a constructivist approach in light of conceptual change theory and phenomenological primitives.
Fria Ventiler : Olika ventilstrategiers effekt på cylinderströmning, emissioner och prestanda i en heavy duty dieselmotor
En del fjällvandrare tycker att det är för tungt att gå med en stor ryggsäck, ett problem som har givit upphov till en idé om ett avlastande hjälpmedel. Företaget Prodelox AB har sedan tidigare påbörjat utvecklingen av detta hjälpmedel. Under detta examensarbete har ett koncept utvecklats med den initiala studien som utgångspunkt. Produktens grundidé är i dagsläget sekretessbelagd och kommer tyvärr inte att redovisas i denna rapport.En användarstudie genomfördes vilket resulterade i en kravspecifikation, produktens definition, samt en djupare bild av fjällvandring och andra friluftsaktiviteter. Denna djupa inblick möjliggjordes med hjälp av context mapping-metoden.
E.ON:s transformatorflöde - en studie av återanvändningen av transformatorer i projekt krafttag
Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

Kastanjemalen Cameraria ohridella : livscykel och utbredning i Sverige 2006
Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas.
In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.
Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?
Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.

Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.
Koldioxidutsläpp vid sticklingsproduktion av pelargonium x hortorum i Kenya jämfört med Sverige :
Long transport of products is an environmental issue discussed to an increasing extent. The consumers are increasingly aware of how far our comestibles really have been transported. The increasing levels of environmental emissions are something that concerns people. The question is nevertheless delicate and many choose to ignore it. This is no longer an option.
Skolans organisering och pedagogiska arbete med svenska som andraspråk : ur ett lärarperspektiv
Research has shown that students with another mother tongue than Swedish terminate elementary school with lower grades in all subjects, compared to students having Swedish as a mother tongue. This fact justifies further research on the forms of teaching Swedish as a second language. Attention has been given to the fact that the students with another mother tongue than Swedish have to cope with "dual learning". Parallel to the learning of a second language they need to obtain knowledge in all other subjects. The purpose of this thesis is to investigate how the School organise the work with students having another mother tongue than Swedish, and to find out how teachers in other subjects solve the problem of having students that struggle with "dual learning".
Revisorernas oberoende ifrågasätts : går det att sitta på dubbla stolar, få dubbla inkomster och ändå bevara oberoendet?
The recent accounting scandals in large companies in both USA and Europe, such as Enron and Scandia, have led to a huge debate about the quality of financial reports approved by auditors who, at the same time, offer consultancy service to their audit clients. Many researchers and experts argued that there is a role conflict when an auditor offers consultancy service to audit clients. They argue that the main duty of an auditor is to verify the truthfulness of the company's financial statements. Giving consultancy service to the audit clients will impair the auditor's role to examine the company's books independently because of the economic bond between auditors and audit clients.As a result of the Enron scandal, the legislators in the USA have made restrictions to how auditors provide non-audit service to audit clients. However, the legislators in Sweden, unlike the US, did not choose to introduce such restrictions.
