Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

Engelfors Trilogy is a three-part fantasy novel consisting of Circle, Fire and The key, written by Mats Strandberg and Sara Bergmark Elfgrens. Circle was nominated for the August Prize award 2011, which is a literary prize awarded each year. The book has also been translated into 25 different languages. Fire came out in August 2013 and is the part of the novel that I will concentrate on in these theses. What I will do in this paper is a queer feminist analysis of the novel's main characters in the book Fire.

The purpose of this thesis was to examine reading groups inpublic libraries from a bibliotherapeutic perspective. Inorder to reach this purpose following questions needed to beanswered: What does the discussion in reading groups looklike? What does the reading groups fulfill for theirparticipants? What is the circle leaders? role? The study isbased on the observations of three reading groups and offive interviews of its participants. With the help of CarolineShrodes theory the study shows that there are few signs ofbibliotherapy in the reading groups. But on the other handthey show similarities with other bibliotherapeutic readinggroups, by being a social venue for its participants.

Syfte/ Syftet med denna studie är att undersöka hur artister använder sig av storytelling som ett verktyg i sitt varumärkesbyggande. Vi har studerat i vilka former historieberättande yttrar sig och vilka berättartekniska byggstenar som ligger till grund för historier inom musikindustrin. Följande frågeställning har utgjort grunden för studien; Hur använder sig artister av storytelling som ett verktyg i sitt varumärkesbyggande?Metod Studien bygger på textanalys i form av en fallstudie. Med en begränsning av två olika fall - Lady Gaga och Rolling Stones ? har vi valt att samla in relevant data i form av textmaterial såsom musikvideor, fotografier, intervjuer, dokumentärer och presentationstext.

It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.

The purpose of this study is to look into if the pedagogues who participate in this study treat children differently depending on their sex. The purpose was then divided in three research questions which were: Attention: How much verbal attention and eye contact with the pedagogue are girls/boys getting? Choice of words: Are there any differences in the choice of words the pedagogues are using against girls/boys? Address: How does the pedagogue address girls/boys, are there any differences? The tone of the voice and how the pedagogue address girls/boys belongs in this category. The study was observed with video camera in four different circle time situations, two circle times for each preschool. Data were then analyzed with an observation schedule based on the three research questions.

Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells.Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgV?) of MALT lymphomas.Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis.Successful amplification was seen in 10/13 cases and sequences of IgV? genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the V?3 family, 2 from V?1 and 1 from the V? 4 family..

        This is a report that describes the entire process of design of a measuring station for rolling resistance. The report is structured with elements of Fredy Olsson's method.The report also includes a brief presentation of HGF, the company that will manufacture the machine. Requirements and preferences are set up and used in a weighting of criteria by which product suggestions are based. These suggestions are used in the evaluation to produce a final draft product. Solutions to major functions are produced by criteria?s. Component selection for all components is performed, a CAD-based model is developed and an economic analysis is set up. FMEA analysis is set up. The report ends with a brief summary, critical review and suggestions for further work..

Today, librarians tasks may sometimes take on an educational aspect, e.g. when designing educational courses. Our aim with this paper has been to extend our knowledge of peoples learning and learning processes in order to better adapt our educational courses for different user groups. We have investigated what eight senior citizens wanted to learn about the Internet, and followed seven of them during their course. We have examined how the group experienced a course about Internet use, and how they described their learning and learning processes.

The aim of this master thesis is to obtain a greater understanding of childrens choice of favourite books, insight in their reading experiences and their thoughts about the reading of these books. We also want to investigate if, and if so, how childrens librarians obtain knowledge of the childrens reading preferences and reading experiences and how they use this knowledge in their work to stimulate childrens reading. To reach our aim we have been carrying out quantitative interviews with six children aged nine to ten years and three childrens librarians working in public libraries. As a theoretical starting point we use the reader-oriented theory and Chambers Reading circle, which states that support from adults is the most important factor in the childs reading process. The empirical results are linked to theories and earlier research and are analysed under four different themes.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

Studien har skett i samarbete med Bjuvs kommun som beviljats bidrag från Kulturrådet för att genomföra RGRM i äldreomsorgen. Vår studie fokuserar på hur deltagande i RGRM-metoden upplevs av omsorgstagarna och om RGRM-metoden har någon inverkan på relationen mellan omsorgstagare och omsorgspersonal. Resultattolkningen leder fram till att deltagande i aktivitet som tillämpar RGRM-metoden, förutom bättre fysisk hälsa och ?hjärngympa? i form av koncentration, också skapar möjligheter för social samvaro, återkoppling via musiken till tidigare minnen och känsla av tillhörighet. I fråga om RGRM-metodens inverkan på relationer så är det framförallt omsorgspersonalen som uttrycker att de får en fördjupad kontakt med omsorgstagarna..
