New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

This bachelor thesis discusses various difficulties with architectural paint research. The difficulties are exemplified through a case study ? a paint research on a furrowed string-course in the southern vault of the Royal Palace of Stockholm, which was carried out November ? March 2009-2010 on behalf of Statens Fastighetsverk. The paint research was made in order to receive information about the string-course and to get inspiration for a renewed color scheme on it. The base material of the string-course is Gotlandic sandstone and the surface of it is furrowed.

Recent years have been very turbulent for most private equity firms. Especially the financial meltdown in global economy has affected the industry, but also the public pressure has made private equity houses change their control strategies towards more conventional methods used in public companies. This thesis aims to put light on the control methods used in listed private equity houses which use a buyout strategy. The paper describes how the control methods change over the different phases the asset experience and how different value generating strategies use altered control methods. Using Merchant's (2003) framework for management control systems and Berg and Gottschalg's (2004) research on value generating strategies in buyouts the thesis shows that action controls as designing instructions for the board and a business plan, together with goal alignment is the commonly used control strategy directly after the acquisition.

Sweden?s health care is continuously subjected to economical cutbacks, which results in enormous workloads. To prevent problems that arise in these situations, it is of great importance to take measures to increase the efficiency of the working process. This goal can be obtained by increasing our knowledge of the body, under both normal and sickly conditions. That is, by sharing knowledge of the various medical service units within Stockholm?s county council and thus elaborates diagnostics.

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

The purpose of this study is to gauge the current state of Swedish library and information science research. LIS is generally defined as a cross- or multidisciplinary subject, according to some coupled with heterogenity or dichotomy within the subject. In light of Jack Meadows?s description of the scientific community growth and scientific communication, the following two research questions are formulated as basis for the study: 1. What are the current themes, what range of theories and methods are used in our research material? 2.

The purpose of this paper is to critically examine and question the use of mindfulness in the workplace. Mindfulness in the workplace can be understood as an organization recipe and is now a so called trend. We believe that there may be an issue of how mindfulness at work is advertised when it is described in such a way that it could be the solution to many organizational problems, such as reducing stress, increasing efficiency, creativity and productivity. To get a better understanding of what mindfulness is and what it can bring to a stressful work, we conducted semi-structured interviews with four mindfulness instructors. We analyzed the interviews from a theoretical analytical framework consisting of both a constructivist perspective and a power perspective.

By studying the forms of work and methods teachers choose for their teaching on the Business and Administration Programme and by examining the experiences gained by these teachers, I hope to gain a clearer insight into how the demands of national policy/governing documents are met in the actual teaching of the courses within the programme. In my qualitative study,teachers in a team from a Business and Administrative Programme have been my informants. The team combines multiple forms of work and methods in line with the intentions of the national policy/governing documents. Students usually have an unbroken school day with block teaching where they work with case studies and interdisciplinary  work. Morals and ethics are integrated in class.

Sammanfattning- ?Tids- och arbetseffektivitet i ett konsultföretag ? jämförelse mellan Lean och HighWay?Nivå: Magisteruppsats i hållbar verksamhetsutveckling och management, 15 HPInstitution: Akademin för ekonomi, samhälle och teknik, EST, VästeråsNyckelord: Tidseffektivitet, arbetseffektivitet och LeanFrågeställning: Hur skiljer sig effektiviteten i arbetet mellan de två systemen Lean och HighWay och skulle det vara en fördel för Hallvarson & Halvarson (H&H) att byta till Lean? Hur skiljer sig tids- och arbetseffektiviteten åt inom de två olika systemen?Syfte: Syftet med studien är att ta reda på om Lean, som från början var utvecklat för produktionssektorn, skulle kunna vara ett mer framgångsrikt system än HighWay för ett tjänsteföretag som konsultföretaget Hallvarsson & Halvarsson.Metod: Informationen har hämtats från vetenskaplig artiklar och litteratur samt internetsidor. Undersökningen bestod av två intervjuer, med system ägaren och VD på Hallvarsson & Halvarsson. Intervjuerna bestod av personliga möten.Slutsats: Förbättringsförslag för ökad effektivitet redovisas, där ett av förslagen är att HighWay skulle kunna införa en process- och kvalitetsövervakande roll med syfte att säkerställa ständigt och omedelbart förbättringsarbete för att uppnå perfektion likt Jidoka-principen..

This paper aims to investigate whether a small organization with small development teams can find a value in leaving a functioning development process to follow a formal systems development methodology, if these organizations can find support in an agile systems development method and in such case the method needs to be adjusted according to the organizations unique conditions.A traditional plan-driven system development methodology includes a number of phases that are carried out sequentially and a completed phase can basically not be resumed. All requirements are specified at the beginning of a project and at the end of the project only one delivery of software take place. This can cause difficulties in for example dealing with changing requirements. Agile system development methods intend to deal with changing requirements and to enable continuous delivery of valuable, working software.In this paper, both the traditional plan-driven methods and agile methods will be explained. Research methodology and existing system development theories will be discussed and a company where the study has been conducted will be presented.

This is a qualitative study with four interviews, in four different preschools, in the same municipality. By making it so, it becomes a case study to describe a phenomenon in a municipality which also is the definition for this investigation. The purpose of my study is to examine what it means, in a municipality, to have different types of introduction at preschool. Where I ask the question why preschools choose to have a specific method of introduction and what are the basics and ideas behind the choice of the method? What significance do these different methods have to attachment theory? What do teachers think about the advantages and disadvantages with their choice of method?The versions of introductions are many and may vary; the duration of the introduction may vary from 1-3 days up to 3 weeks.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
