Emissioner i slutna utrymmen Med speciell inriktning på emissioner av formaldehyd och organiska syror
This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.
Dimensionering av grundläggning med hjälp av Eurokod
AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes. The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.
Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.
"Antingen så lägger man sig ner och dör eller så försöker man" : En intervjustudie om några förläggares och bibliotekariers inställning till e-bokshantering på svenska folkbibliotek

In Sweden e-books are still representing only a small amount of all the library loans and an even smaller amount of the commercial book market.The methodological and theoretical ground for the thesis is Grounded Theory, and the survey is based on interviews with publishers, librarians and distributors.The conclusions of this thesis are that the public libraries lack resources to invest in e-books, and that they also lack in knowledge about the media and its readers. It also exposes that both internal and external collaboration efforts need to be further developed.
En studie om studenters upplevda kontrollokus och akademiska motivation i relation till arbetslivserfarenhet och ålder
Syftet var att undersöka skillnader mellan olika studentgrupper uppdelat efter år av arbetslivserfarenhet och ålder. Detta för att se om arbetslivserfarenhet och ålder hade någon betydelse för studenters interna motivation, externa motivation, amotivation och kontrollokus. I tvärsnittsstudien deltog 71 studenter (60 kvinnor och 11 män) från en högskola i Mellansverige och deltagarnas ålderspridning var 19-47 år. Undersökningen byggde på två enkäter; The Academic motivation scale (AMS-C28) for college students (Ryan & Deci, 2000) och Academic locus of control scale for college students (ALC) (Trice, 2013). Statistiskt signifikant skillnad fanns mellan en studentgrupp som var 19-22 år gamla och en studentgrupp som var 26 år och äldre på kontrollokus, där resultatet visade att den äldsta gruppen upplevde mer externt kontrollokus än den yngre gruppen.
