In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.

The background for this thesis is that at the beginnings of 1980´s the National Board of Forest started an experiment of lime dressing to reduce acidification in forest soil and in ground water. The purposes of this report are to explain organization?s, government?s and private landowners viewpoint on lime dressing and vitalization fertilization, some socio-economic aspects are presented. The general conclusions are that the majority of the interested party?s are positive to vitalization fertilization but the forests owner?s in generally need much more information about this topic..

Abstract (in English)The task for the diploma work was to develop methods for measuring of moisture content by the Karl Fischer method, in jam, jelly sweets, and fudge.The start premises was a for the company whole new equipment, which should be started up. Then programs should be developed for different kind of samples.In the task it was as well included to develop methods for dissolving the different kind of samples, since the Karl Fischer method demands completely dissolved sample material..

The project was initiated by Medipharm which produce microbial inoculants which used as additives to preserve forage. The main goal was to test three inoculants to produce maize silege. The following Medipharm produced inoculants were tested, Milab 393, Lactisil Wolecrop II, Lactisil 300 2. An untreated control was included in the study. The trial was done at Swedish university of Agriculture and Science in Alnarp, Sweden. Eurostar was the cultivar of the maize and was grown on 20, 5 hectares.

This is a qualitative case study of young womens? experiences of blogging about One Direction on the social media/microblogging platform Tumblr. The aim of this study was to find out what fan blogging is and why fans blog. We did this by creating an account on Tumblr where we invited young women between the ages of 16?29, who had active fan blogs dedicated to One Direction, to answer an open-ended questionnaire.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Examensarbetets titel: Implementering av uppförandekod i Kina ? Like a bridge over troubled water Seminariedatum: 21 Januari 2009 Ämne/kurs: FEK K01, Examensarbete kandidatnivå, 15 ECTS Författare: Johanna Jeppsson, Anna Svensson Henning och Gustav Petersson Handledare: Gösta Wijk Nyckelord: Uppförandekod, Implementering, Kina, Sverige, Kultur Syfte: Syftet med denna kandidatuppsats är att undersöka om nationella kulturer och organisationskulturer kan ge upphov till svårigheter med implementering av uppförandekod, och vilka dessa svårigheter i så fall kan vara. Metod: Uppsatsen är en kvalitativ studie som till stor del grundas på semistrukturerade intervjuer med tre svenska fallföretag inom modebranschen med produktion i Kina. Uppsatsen har en abduktiv ansats. Teoretiska perspektiv: Uppsatsen har främst två teoretiska baser, Hofstedes teori rörande skillnader i nationella kulturer samt Scheins tre kulturnivåer.

The first regulation concerning the protection of shores was introduced in 1950. The purpose of that regulation was to "secure the general publics condition of an outdoor life". The protection has been sharpened over the years and in 1975 a general protection of the shores was introduced, which meant that all land was protected within 100 meters from the shoreline. In 1994 a supplement was made with the purpose to "preserve good conditions for animal and plants on land and in water". The Swedish Environmental Protection Agency (EPA) did an inquiry of the shore protection regulations commissioned by the Government in 2001. The inquiry pointed out that there were big lacks in the exemption decisions.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

Emwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected.

This study examines if men and women have different conflict resolution styles in different situations. There are several studies in this area, but the results are contradictive and they don?t take consideration to the context. The study is an explorative, quantitative examine in the form of a self-report questionnaire, where different scenarios are described. These scenarios are based on the parts of the context that this study focuses on; the relationship to the other part, the perception of treatment and the place where the conflict occurs.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.
