In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Syftet med vårt arbete är att undersöka vilka möjligheter och hinder våra elever har när det gäller skriftspråket på arabiska. I vårt arbete har vi använt oss av en kvalitativ undersökningsmetod och vi valde att göra intervjuer med 4 pedagoger och 8 elever varav 4 på mellanstadiet och 4 på högstadiet. Vi har använt oss bl.a. av Pauline Gibbons litteratur ?Stärk språket, stärk lärandet? och ?Lyft språket, lyft tänkandet.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

This report describes procedures and preparations made for developing a mobile application.Using a questionnaire and usability tests, I have developed a design document for a parkingapplication for the iPhone 4. The purpose of the application is to help drivers find allowedparking spaces thus making roads safer for everyone while the driver avoids parking tickets..

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).

The aim of this study is to investigate how the Swedish language proficiency of pupils in vocational programmes in 1977 was measured and assessed with the aid of a national achievement test, and to investigate whether vocational pupils today, in 2014, have similar language proficiency to that of pupils in the 1970s. The study also discusses how the design of the national achievement test from 1977 reflects the view of knowledge that prevailed in society and in the policy documents. The material for the study consists of a total of 75 national achievement tests, 40 of which were taken by pupils on a vocational programme in 1977 and 35 by pupils on a vocational programme in 2014. The national achievement test consists of two parts, the first of which focuses on isolated elements of language proficiency, while the second involves free text production. The material was analysed quantitatively in accordance with the correction material from 1977.

In this study, I have investigated whether there is a usefulness for the individual on the basis of Kierkegaard's speech in Work´s of love of our duty to love the people we see. My main conclusions are as follows: Infinite resignation of Fear and Trembling have a greater effect on a relevant ethics than faith movement. Aspects to change my own attitudes about love, dare to belive in the love of the other, and forgiveness as a need is relevant to the ethics I seek. But above all, love itself is the most useful aspect out of a kierkegaardian perspective..

Uppsatsen syftar till att genom en analys av tre tal undersöka på vilket sätt USA:s president Barack Obama använder sig av berättelser om sin familj och sin bakgrund i sina tal för att försöka stärka sitt ethos. Uppsatsen har tre huvudsakliga frågeställningar: När i talen pratar Obama om sin familj och bakgrund? Vad i dessa berättelser kan höja Obamas ethos och skapa förtroende för honom? Vilka retoriska grepp använder Obama för att försöka få så många som möjligt att känna att de har något gemensamt med honom? Det material som analyseras i uppsatsen är tre tal framförda av Barack Obama. Det är det presentationstal (The Keynote Speech) som han höll på Demokraternas konvent 2004 när John Kerry skulle nomineras till presidentkandidat, det tal Obama höll om sin pastor när denne uttalat sig rasistiskt om vita (A More Perfect Union) samt det segertal han höll i Grant Park i Chicago 2008 då det stod klart att han blivit vald till USA:s 44:e president. Dessa tre tal har valts ut som analysmaterial då de dels rent kronologiskt speglar olika tidpunkter och avsatser i hans karriär och dels visar på tre olika sammanhang, ett då han egentligen presenterar en annan person (Keynote Speech) men ändå lyckas göra det även till ett presentationstal av sig själv, ett där han snarare ger ett slags försvarstal (A More Perfect Union) och ett som är mer präglat av glädje och förhoppning (The Victory Speech). Den teori som presenteras i uppsatsen rör framför allt ethos, den retoriska situationen och topikläran, men en kortare genomgång av den klassiska retorikens tre talgenrer, partesläran, publikbegreppet och presidenttal genomförs även.

 Background: Earlier studies show that 30-92 % of ACL reconstructed return to their pre-injury physical activity. It is not clear why some people do not return.Purpose: The purpose of this study was to investigate the return rate to pre-injury sport among ACL reconstructed men. Another purpose was to characterize those patients who return and those who do not.Metod: A Web-based questionnaire with questions about returning to physical activity was sent out during the spring of 2012 to 93 men who had undergone an ACL reconstruction 6-40 months earlier and who, after 6-40 months after surgery, were evaluated with validated strength tests and self-assessment outcome measures.Results: At 12 months after surgery 56 % of the subjects had returned to their pre-injury sport. If the criteria were set higher ?back to the same- or a higher level? 14 % had returned.

Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high seed vitality in store, regular germination tests need to be conducted. It is important to get a correct viability status, but the knowledge of seed dormancy in the cultural relict plants is often poor. The objective of this study was to investigate how seed dormancy is affected by cold stratification. The study includes 31 accessions from 28 species with the purpose of establishing germination protocols.

Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested.  The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.

Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.

 This paper is about the conflict between the Middle East and the Western world after the Danish newspapers? cartoon publications of the prophet Muhammed in October 2005. The conflict resulted in massive reactions in the Middle East and the Danish-Swedish dairy company Arla Foods, was boycotted during six months in 2006. The aim of this study is to describe how the biggest Swedish daily newspaper,Dagens Nyheter and three Saudiarabic newspapers Al-Hayat, Al-Watan and Shark Al-Awsat described "the Other" during the crisis in the year of 2006. Another aim is to describe how Arla Foods managed the consumer boycott.
