Luftprovtagning samt analys av mono- och diisocyanater

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

"Att ingjuta mod och lust" : om barns delaktighet på barnbiblioteket TioTretton

The focus of this two year's master thesis is on participation of children at the TioTretton Library, a library strictly for 10-13 year olds. No adults, except the library staff are allowed in this library. To build on this aim the objectives of this thesis is centred on the questions:How does the library staff view their specific library's mission? What are the conditions for children's participation at TioTretton Library? Based on the relevant theory of participation, how participatory are the children in the library's activities? What significance has TioTretton Library's work with children participation for the children's ability to empowerment?The theoretical framework is mainly centred upon the Ladder of Participation designed by R. A.

Mannen, myten... Stereotypen? : En kvalitativ innehållsanalys av hur manliga stereotyper konstrueras i tidningen Cafés reklamannonser

The discussion about gender and ideals shown in mass media is a subject of great importance for the society in general. Media is playing an essential part when it comes to establish standards and values and we are constantly exposed to all types of impressions, whether we are aware or not. It is therefore of great importance that we understand how stereotypes are built and to gain a deep knowledge that would enrich the area of Media and Communication Studies.The aim and focus of this study was to analyze how male stereotypes is communicated in print advertising and how visual means of expressions helps to construct the masculinities shown. From a semiotic analysis of seven print adverts appearing in the Swedish lifestyle Magazine Café were we able to gain a thorough understanding about how male stereotypes are communicated and built.The result showed that different kinds of stereotypes are in fact used but it is still a hegemonic masculinity that is predominating. Traditional male characteristics are still in use but we were able to see strong indications of effemination, sexualizing and objectifying.

Konstruktion av anordning för att undersöka förslitning av syrebärarpartiklar för kemcyklisk förbränning

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

En sjuk arbetslinje? : En studie av rehabiliteringskedjans hälsoeffekter

This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.

GROT uttag i Värmlands Län : Extraction of Harvest residues in the County of Värmland

På uppdrag av skogsstyrelsen skall beräkning av framtida potential för uttag av skogsbränsle (GROT) vid slutavverkning av skog göras. Skogsbränsle utgörs till stor del av GROT som är avverkningsrester i form av GRenar Och Toppar. Flera faktorer påverkar hur mycket skogsbränsle det blir vid uttag efter avverkning. Stora snabbväxande träd har en större gren- och barrmassa. I detta arbete har lämplig mark, beståndens ålder och sammansättning selekterats ut med hjälp av GIS för att erhålla största möjliga volym GROT.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

Vad kostar deltid? Kvinnors deltidsarbete ur ett pensionsperspektiv

Mothers of small children often work part-time in Sweden. Since old age pensions are based on lifetime income, part-time work leads to lower pensions, as long as there is no compensation from non-actuarial benefits such as minimum pensions. In this paper, I investigate whether different components of the Swedish pension system provide incentives for part-time work among women. The analysis is performed through a simulation of future pensions for 9 typical women in a certain cohort. For three levels of education, I compare pensions of women with different labor market participation rates in different growth scenarios.

Kunskapens rum - en studie av Orkanenbiblioteket

The aim of this master´s thesis is to explore how a library through it´s spatial distribution expresses, and is an expression for, a view of knowledge. This is done by an analysis of the Orkanen library at Malmö Högskola. Questions posed in this study are: What view of knowledge is mediated through the spatial system and in the shelving of books? What view of learning is expressed in the spatial distribution of functions and artefacts?The theoretical framework of this thesis has two fundamental features. One, which focuses on theories of social space, a part that is mainly influenced by the theories of space syntax.

Två dagar senare ... En uppsats om helgens guldkant

About a year ago, Göteborgs-Posten, one of Sweden's largest daily newspapers, decided it was unprofitable to continue producing their feature-style weekend magazine, Två Dagar. Standing at a crossroads,not wanting to stop producing the weekend magazine altogether, they decided to outsource. Spoon Publishing AB, a content agency with strong ties to Göteborg, were assigned with taking over the production.Going forward, Spoon has taken over a majority of the responsibility for the conceptual work and actual production, all with the main purpose of reducing cost and increasing efficiency.Normally Spoon does content marketing for a wide range of customers in an equally wide spectra of channels, from print to radio, television and web.The main purpose of this essay has been to investigate and establish whether the journalistic integrity and quality has in fact been maintained despite the weekend magazine being outsourced. We have analyzed selected editions of the magazine, first and foremost inarticles under the vignette fashion, using a qualitative method for content analysis, scrutinizing everything from the denotation of single words to the big picture. This specific vignette contains the most frequent contributions by in-house, or at least reappearing, journalists.Perusing the material in Två Dagar, we have come to the conclusion that the magazine has indeed retained its level of quality and still reflects the same core values as before being outsourced..

The distribution of Moose (Alces alces) during winter in southern Sweden : a response to food sources?

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

Pandemin som hotar Sverige : En undersökning av hur risken för svininfluensan framställs i kvart-i-fem-ekot.

The aim of this thesis has been to examine how the risk for the swine flu was represented in the Swedish Radio news broadcast Ekot 16.45 during different phases of the pandemic in 2009. We wanted to study how the risk was described in different discourses and periods? Were the participants in the reporting calming or warning the listeners in relations to different aspects of the swine flu? What consequences for the community were reported in the broadcasting?To find the answers to our questions, we analysed 13 features about the swine flu broadcasted in Ekot?s main news broadcast Ekot 16.45. We used critical discourse analysis inspired by Norman Fairclough.We identified four types of discourses in our text, a journalistic discourse, a medical discourse, a nationalistic discourse and an authority discourse. The main discourse was the medical one.
