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.

Utvecklingen inom förmedling av bostäder har gått snabbt sedan internet blev en del av vårvardag. Idag vänder vi oss online för att hitta vår nya bostad och detta ger möjligheten attfölja bostadsmarknaden på ett helt nytt sätt. Denna uppsats undersöker relationen mellanSveriges bostadsköpares sökbeteende på Sveriges utan tvekan största bostadssöksajt Hemnetoch Riksbankens räntebesked.Genom att analysera det totala antalet sökningar gjorda på bostadsrätter, hus och fritidshus vidav Riksbanken rapporterade räntehöjningar, räntesänkningar samt en lämnad oförändradreporänta försöker författarna se om sökbeteendet ändras. Sökbeteendet fyller funktionen aven ny möjlig indikator för efterfrågan på den Svenska bostadsmarknaden. Den statistik somundersöks sträcker sig från tidsperioden april 2011 till april 2013.Resultatet av studien visar att Riksbankens räntebeslut, oavsett karaktär, inte ger någon effektpå antalet sökningar.

Advertisers of today are facing a great challenge in a landscape where it becomes even more difficult to break through the clutter and convince consumers to buy their products. In order to succeed, they need to come up with new ways of communicating with their customers. The purpose of this paper is to investigate if micro-blogging could be considered an effective media choice in order to enhance the perception of brand associations and traditional communication effects. The subject is of interest as brands are putting increasingly more resources into this communication channel. However, at the current date the marketing effects of micro-blogging is unexplored in academic research.

This thesis aims to study whether the Swedish corporate law is in need of additional rules regarding the composition of the board of directors from a gender equality point of view. Sweden is internationally a state that is far ahead when it comes to creating equal opportunities for all its citizens. The Swedish labour market consist of men and women to an equal degree, although this is a phenomena that is not reflected on the leading positions in the larger limited corporations listed on the stock exchange. This is a trend that definitely needs to be attended to, since women can provide crucial knowledge that is important not only to the individual corporation but also to the society as a whole. This is strengthened by the fact that demographic differences in boards stimulates creative solutions and well reasoned suggestions.The opponents to legal measures regarding affirmative action base their arguments on the fact that the shareholders right of ownership is limited as a result of such measures and also that rules regarding self-regulation through corporate governance is preferable.

Sedan införandet av euro som gemensam valuta har interna obalanser inom euroområdet växt sig starkare till följd av reala apprecieringar i speciellt Portugal, Irland, Italien, Grekland och Spanien. Detta har lett till att ländernas internationella konkurrenskraft försvagats. För att få bukt med de interna obalanserna krävs det att länderna återfår sin internationella konkurrenskraft, deras varor måste bli billigare i jämförelse med deras handelspartner. Detta kan komma till stånd genom reala deprecieringar. Hösten 2008 drabbades världen av den djupaste ekonomiska nedgången sedan andra världskriget, något som förvärrade situationen för de krisande euroländerna.Uppsatsen belyser de interna obalanserna inom euroområdet och diskuterar teoretiskt på vilka sätt länderna kan få stånd till reala deprecieringar när det inte finns någon växelkurs att ändra mot de andra euroländerna.

Web services are now a day often mentioned when speaking of systems communicating with each other online. This master thesis describes how we, with a grounded theory, developed a web service from scratch and then used it to describe how to develop a method for this case scenario. The purpose of the web service is to simplify the information exchange between Infra Gaming, which is the company who assigned this project to us, and their customers. This master thesis is not a guide to how you develop a web service. It is a master thesis that describes how we, in three steps, solved the assignment from Infra Gaming and our problem, with a web service..

Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.

Today's real estate buyers value the purchase different today compared to a decade back. Previously it was the return value that ruled the market. This has created problems when the broker must allocate the purchase price of the property's various elements, because non-monetary values such as forest for leisure, recreation, and the feeling of owing has increased in recent years and an increasingly important part in the valuation process. The assessed value can be a guide, but is perceived today to be stereotyped to put a fair value at the individual item. The purpose of this study was to provide the real estate agent decision support and a guide to the likely value of accounting for the purchase price. The report is written on behalf of LRF Konsult. The result is based on a questionnaire survey which was conducted in June 2014 among all those who had bought a farming property in Dalarna and Gävleborg province mediated by LRF Konsult in 2013. The report was made with a split to see if the valuation and motives differ between new and previous owners. It was possible to see a big difference in the reason for the purchase, where a large share of new owner bought the land for capital investment, in contrast to previous owners whose biggest group bought for an active use. At several points it was possible to identify a higher non-monetary value of the new owner from the previous landowner.

Fertilitetsegenskaper har ofta låga arvbarheter och selektion baserat på fenotyp är ofta ineffektiv och långsam. För att förbättra fertilitetsegenskaper som ovulationsmängd och kullstorlek hos får är det effektivast att selektera avelsdjur utefter deras genotyp. Olika mutationer i gener tillhörande transforming growth factor-? (TGF?) superfamiljen har visat sig påverka ovulationsmängd och kullstorlek hos får. Dessa gener är BMPR-1B, BMP15 och GDF9.

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Syftet med denna uppsats var att undersöka om RTK ? tekniken (Real Time Kinematik) i framtiden kan komma att användas vid lotsning i Sverige, ombord på fartyg med begränsat vattendjup under kölen.  Squateffekten påverkar fartyg vid passage över grunda partier i farleder och i kanaler. För att minska ner på squateffekten så kan man minska ned på farten eller ändra fartygets trim. Studien har utformats utefter en kvalitativ metod, som handlar om att man väljer att bearbeta och analysera sin information genom att verbala analysmetoder används. Detta har genomförts genom att intervjua ett antal utvalda lotsar som både är insatta samt mindre insatta i tekniken.

Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. In the wild there are mechanisms that make horses avoid mating with close relatives. When selection is done by humans this mechanism is removed and intensive breeding for a few traits, for example good racing results, can become a problem.

In this essay, I have examined and discussed the similarities and differences between christology in the thought of Cyril of Alexandria and Martin Luther, and further, to what extent Luther may have been influenced by Cyril in his doctrines of christology and Christ?s presence in the Eucharist. By reading texts written by Cyril as well as by Luther, I have tried to describe the position of each of the theologian?s. In the next step, I compared the thoughts of Cyril and Luther, and tried to show on both similarities and differences.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.
