En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Livet efter hjärtinfarkten : En litteraturstudie om kvinnors erfarenheter

Hjärtinfarkt är den dominerande dödliga sjukdomen i Sverige, vilket fler kvinnor än män avlider i. Kvinnor insjuknar senare i livet och upplever fler och mer diffusa symptom än män. Stress är en vanlig förekommande riskfaktor, vilket kan skapas från samhällets förväntningar på kvinnor. Det finns förväntningar om omsorgsfulla kvinnor som samtidigt ska prestera bra både på arbetet och i hemmet, vilket genererar stress. Förväntningar från samhället och kroppens biologi skiljer sig mellan män och kvinnor.

Från väpnad oppositionsgrupp till politiskt parti- En komparativ studie om transformeringen och institutionaliseringen av RENAMO, FRELIMO och SWAPO i Moçambique och Namibia

This thesis explores and compares the former armed opposition groups; Mozambique National Resistance (RENAMO), Front for the Liberation of Mozambique (FRELIMO) and South West Africa People's Organization (SWAPO) transformation processes into political parties. The first question addressed is; What factors determines the ability of these armed opposition groups to transform into political parties after armed conflict? The question is addressed through four structural and organizational factors; international involvement, the organizations ideology and identity, their ability to change inter-elite relationships and their ability to change collective incentive strategies. The second question addressed is if the transformations process can affect the parties? degree of institutionalization? The degree of institutionalization is examined through the party's adaptility, complexity, autonomy and coherence.

Upplevelser av rovdjursturism : en studie av resereportage

This essay contains a discoursive analysis of fifteen travel reports from five of the largest papers in Sweden. The travel reports contains recaptions from wildlife tourism experiences were the predators are the main target, or at least one of the main targets. Seven of the reports are from Sweden and eight of them from Russia, Rumania, Finland, Turkey and the United States. Predators in this essay aims to those in Sweden called ?the big five?, these are: bears, wolves, lynxes , wolverines and golden eagles.

En litteraturstudie om sjuksköterskors bemötande av patienter som drabbats av depression efter stroke.

Stroke är en hastig begränsad störning av hjärnans funktion. Störningen varar mer än 24 timmar och har en vaskulär orsak. Efterförloppet av stroke kan leda till depression hos de drabbade, så kallad post stroke depression (PSD). PSD kan leda till en försämrad rehabilitering samt ökar både lidanden och mortaliteten hos patienter. Syftet med denna studie är att beskriva hur sjuksköterskor kan identifiera och bemöta patienter som drabbats av PSD, samt vilka konsekvenserna kan bli hos patienter.

Förnuft och känsla : En studie av kokböckers visuella kommunikation under det tidiga 90-talet och sena 00-talet

The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material.

Fri vilja? : En jämförelse och rimlighetsprövning av Augustinus och Luthers syn på den fria viljan

The aim of this essay is to examine what happens when Veronica Roths Divergent-trilogy is read with a lutheran theological pre-understanding. Using reader-response theory and lutheran theology written for and in a post-modern context, three lutheran figures of thought are presented as one way of understanding the trilogy. The conclusion is that it is possible to reveal lutheran ideas concerning justification, guilt, forgiveness, mercy and self-sacrificing love in the Divergent-story. .

Rökgaskondensering och skrubber till vedeldade villapannor :

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?

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.

Synen på "den andre" i ett segregerat område i Kalmar : en studie gjord ur två utlandsfödda mäns perspektiv

Edward Said's book Orientalism (1978) is the most important reference point in the post-colonial theory and describes how the West is dominant over the Orient. There is a clear distinction between "us" and "the other" and the purpose of this study is that, from a postcolonial perspective, focusing on Said's theoretical concepts "the other" and "discourse", examining how two foreign-born people with ethnic backgrounds living in the same place, are looking at themselves, at other foreign-born and native Swedes. My questions to answer this are; ?what are the concepts of "the other" and "discourse" and is it possible to use these concepts to examine how foreign-born people are looking at themselves, at other foreign-born and native Swedes in a specific location??, ?who is "the other" in a place where there are almost as many native Swedes as foreign-born??, and ?how do these two foreign-born people with ethnic backgrounds perceive Norrliden as a place and what effect has that place had on their identity?? I have used a post-colonial philosophical ground and a qualitative approach, focusing on two different interviews with two men, living in Norrliden. In Norrliden almost 50% of the inhabitants are foreign-born were both of the interview-persons are feeling safe and secure.

Henry Chinaski : Charles Bukowskis romanfigur i ett mansforskningsperspektiv

Till min uppsats valde jag att koncentrera mig på två verk, Post Office och Factotum, av författaren Charles Bukowski (1920-1994). Huvudpersonen i båda romanerna kallas Henry Chinaski och är en mycket komplicerad karaktär. För att kunna analysera dennes självdestruktivitet samt syn på kvinnor och arbete anlade jag ett mansforskningsperspektiv, något som jag också utförligt beskriver..

Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
