In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

The purpose of my study is to investigate the wideness of working with fiction in education during the early years in primary school. I want to see in what way fiction is involved and why the teachers choose to work the way they are with fiction. I also want to see what kind of effects this work could have on the development of the pupils. I've done interviews with four teachers to find out about their opinions when it comes to involve fiction into the education. The teachers are all working with pupils between nine and eleven years old.

Den här rapporten undersöker om och i så fall hur webbplatser kan användas som ett återkommande inslag i matematikundervisning. Bland annat Skolverkets utvärdering av grundskolan 2003 visade att matematiklektioner av många elever upplevs som långtråkiga och enformiga. Med rätt utformade applikationer för dator och Internet kan kanske ett medium för ett annorlunda och för eleverna mer engagerande sätt att lära matematik erbjudas. Inom det här projektet konstruerades en webbplats med uppgifter som nästan uteslutande utformats som små spel och sedan delat sin i nivåer efter svårighetsgrad. För att klara en nivå och på så sätt ta sig vidare till nästa behöver en elev först klara alla uppgifter på den aktuella nivån.

In the field of maintenance management there are but a few models an organization can use. The one model that has risen to the status of being the de facto standard in Sweden is pm3(på maintenance management model). The aim of this study is to lay the groundwork for a new method of evaluate the use of pm3within organizations. Today there is no uniform way of performing such an evaluation, which is necessary in order to diagnose the performance of the systems maintenance organizations.In the process of creating our own method for performing this kind of pm3audit, we further developed the ideas from a study by Lagsten & Nordström (2013) that was performed at the county Region Skåne. The authors of that study had developed ideas about using method rationale as a basis of creating a method for pm3auditing.

Sammanfattning Syftet med detta examensarbete är att undersöka vad några elever i årskurs 7-9 har för attityder till skolämnet geografi. För att kunna ta reda på detta har jag valt att använda mig av en enkätundersökning som innefattar två olika delar, den första innehåller 20 frågor om vad eleverna är intresserade av och den andra innehåller 10 påståenden om ämnet geografi som eleverna får ta ställning till. I resultatet visar det sig att eleverna i årskurs 7-9 är mest intresserade av naturkatastrofer, som till exempel, tsunamis, jordbävningar m.m. Däremot finner eleverna inget intresse av växter i deras närområden och det ekologiska jordbruket. Slutsatsen är att eleverna tycker att ämnet geografi är ett viktigt ämne i skolan samtidigt som de har lärt sig mer om var olika länder, städer ligger snarare än andra delar ur geografin..

The aim of the study is to research if the Sweden Democrats portray themselves in a way that can be described as populistic and xenophobic and also if this portrayal has changed over time.In order to do so, the terms of populism and xenophobia has been defined by research and put together into two separate ideal types. Through the eyes of the two ideal types and their traits, four of the party programs of the Sweden Democrats have been researched to look at how they express themselves in the programs and if it can be connected to some of the traits within the two ideal types.The conclusion is that some of the traits are to be found in the programs, and that this also varies over time. From showing signs of both populism and xenophobia, the populistic traits become less over time, while the xenophobic ones instead increases..

Denna studie är en undersökning av hur elever i år 6 uppfattade det geografiska rummet, vilka omvärldsbilder elever i skolan innehade, hur de påverkades av olika intryck från omgivningen samt om elevernas omvärldsbilder förändrades under en termin. Att inneha en omvärldsbild innebär att ha en föreställning om hur den rumsliga världen ser ut och förhåller sig. Undersökningen var av empirisk art och bestod av en namngeografisk undersökning av geografiska objket i Sverige, elevernas ritade bilder av världen, intervjufrågor samt en kartförståelseuppgift. Studien genomfördes vid två olika tillfällen för att se på eventuella förändringar i elevernas omvärldsbilder. Studien visade på att elevernas omvärldsbilder påverkades, utvecklades och innehöll all den information individen mötte och hade med sig sedan tidigare om den rumsliga världen.

The present essay aims to understand the work of art as place on the basis of Martin Heidegger?s conception of work in Der Ursprung des Kunstwerkes from 1935. That is, a place that cannot be understood in accordance with the physical-technological space, but which cannot either be thought of as mere temporal spacing. This is accomplished by reading Der Ursprung des Kunstwerkes through the shorter essay Die Kunst und der Raum from 1969. Despite the time difference, Die Kunst und der Raum opens up Der Ursprung des Kunstwerkes in such a way that the work cannot be understood as if it were only a temporal event ? as the cause initiating a temporal process or succession of truth.

The intent with this paper is to investigate the medieval habitation in central Old Uppsala. This time-period has over the years been neglected. Therefore I wish to summarize and ana-lyze the medieval habitation to see what can be said about its continuity, and also to investi-gate why it is located in certain areas.Due to the amount of source material I have limited my investigation area to the central Old Uppsala. It is possible that this limitation will affect the result of the research but without the limitations the investigation area would have been too large to handle.The source material has been collected from excavation reports and the summarized. My theory is material culture and material agency.

Denna forskningsöversikt handlar om effektiviteten av platsbaserat polisiärt arbete, som fokuserar på små geografiska områden med hög kriminalitet. Har platsbaserat polisiärt arbete en brottsminskande effekt? Minskar bara en viss typ av kriminalitet? Flyttar brottsligheten bara på sig? - Genom lämpliga sökord och välkända databaser valdes de studier ut som hade bra utvärderingsdesigner. Resultatet blev 14 studier varav 9 randomiserade experiment, 4 kvasiexperimentella studier och 1 metaanalys. Översikten visar på en delad bild när det kommer till signifikant effekt vid brottsminskning.

This project details the process of converting and transferring a turn-based paper prototype to a digital real-time format. The projects goals were to see how well the original feeling could be transferred to real-time and how the transition itself went. The project have been completed with the help of the programmer Mikael Gullberg. The practical part of the project was executed between the dates of 25/4 ? 2/5.

För att nybörjaranvändare enklare ska kunna påbörja felfri interaktion med ett system är systemets grad av lärbarhet en viktig aspekt att ta hänsyn till. Trots detta finns inga självklara alternativ till hur lärbarhet ska mätas och utvärderas, framför allt inte på ett snabbt och kostnadseffektivt sätt. Det här examensarbetet har därför bidragit med att lägga en grund för en ny utvärderingsmetod för lärbarhet, SLIM - Simplified Learnability Inspection Method, baserad på relevanta faktorer från befintliga metoder och Linja-ahos (2005) riktlinjer för lärbarhet. Två grupper, experter och icke-experter inom användbarhetsdesign, testade metodens huvudfas individuellt på en prototyp av ett system som ska användas för att skicka SMS via webben. Resultaten från en första validering har visat att metoden i allra högsta grad är tidseffektiv, samt har indikerat att personer så väl med som utan expertkunskaper om användbarhet och lärbarhet kan tillämpa metoden för att i likvärdig utsträckning upptäcka lärbarhetsproblem.

A study of southern pudu (Pudu puda) was performed at the zoo Nordens Ark in Bohuslän, Sweden during twelve days in Mars and April 2014. Observations were performed during twilight. Time budget and enclosure use was examined, when the animals had access to the whole enclosure of 1000 m2 or a smaller part of the enclosure of 200 m2. There was almost no difference in time budget between the two enclosure sizes. At both enclosure sizes the animals spent most of the time at a place that was hidden from outside the enclosure. The hidden place was situated in the house.

In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.
