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.

"En inställd spelning är en spelning det också..." : Ulf Lundells olika realiteter och identiteter i romanerna Jack, En varg söker sin flock och Värmen
Ulf Lundell is one of the most famous songwriters and authors in Sweden. He has written fifteen works of fiction and they?ve all same theme ? a lonely man trying to look into his own past life. They are all built on a character, writing from an I-perspective, having a bit of Lundells own biography in there?s personality. The aim of his thesis is to find out how Ulf Lundell presents him self in his fictive characters, and will trace the authors development from a psychological point of view.
"Det är det största beviset på kärlek, att lämna bort för att skapa ett bättre liv" : En kvalitativ studie om att vara internationellt adopterad
I meet in my work as art teacher many students of different descent, were they, or their parents, have different school experience than the Swedish. This, in combination with therecent discussion after the Muhammad caricatures about the banning of images in Islamic religion, made me curious to study what art education in a Muslim country looked like. I went to visit the Maramra Egitim Köyü school in Istanbul, Turkey, and especially their art classesfrom grade five to eight, which are the same age of students that I have been working with thelast ten years. This was my first visit to Turkey.The question I ask is: What does the practice of Turkish art education look like, using the Marmara school as an example. Which discourses can I identify in the art teacher practice? What surprised me the most was the frequent visual exposure of the founder of the Turkishstate, Kemal Atatürk.
Handlingsfrihet i ekonomiskt bistånd: en studie om organiseringen och handläggandet av nyansökningar
The Swedish welfare organisation is built on the fact that the legislation gives the municipalities and social workers guidance and direction how to assess cases. Through out this the clients have right to be assessed both equally and individually. How is this done? The purpose of this paper was to examine the effect of the organisation referred to the social workers ability to discretion and the evaluation of the assessment in first time applications of social assistant cases. The purpose was also to look for variations in decisions and if these could be explained out of organisational and assessment effects.
Higgsbosonen, standardmodellen och LHC
This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.
Tjejer vs. killar på Facebook : En studie om ungdomars identitetskonstruktion och deras syn på andras identitetsskapande på Facebook sett ur ett genusperspektiv
The purpose of this study was to examine the experience of organizational culture among salespeople at a specific workplace. The purpose was also to investigate what motivates these salespeople in their work and the impact culture has on their motivation. We have used a qualitative research method to collect the empirical material. With the help of seven interviews, including six salespeople from one of Sweden?s biggest electronic retailer and also one information interview with a sales consultant, we attempted to find the answer to how they perceive the organizational culture and how it affects their work motivation. The following questions are used to fulfill this purpose: ? How do the salespeople experience the organizational culture? ? What motivates the salespeople in their daily work? ? What effects does the organizational culture have on the salespersons motivation? As analytical tools we have used are the concept of organizational culture, Schein's description of the three components of culture and Herzberg Motivation-Hygiene theory. The results of the study indicate that the salespeople experience a positive organizational culture and that this culture promotes fellowship and unity between colleagues, which in turn contributes to an enhanced motivation.
Ideon Forskningspark : yttre arbetsmiljö i ett industriellt landskap
Abstract
Ideon Science Park was built on the edge of Lund city in mid-80ies. The Science Park was surrounded by open farm land and Lunds Faculty of engineering(LTH). The architecture, the facades of the buildings, were placed to face the faculty.
The Science Park has since then grown, and the actual front of the building is no longer faced towards LTH. The people working at Ideon are met by the backside, the meeting with Ideon is primarerly a meeting with fields of parkinglots.
The initiative to this thesis was taken by Ikano Fastigheter AB, one of two real estate owners of Ideon Science park. Their aim is to make the area easier to orientate, they want it to be more internally connected and with a stronger identity.
The thesis is mainly dealing with two questions conserning Ideon Science center.
Ett gammalt kulturlandskap i Vindelfjällen : skogshistoria och markutnyttjande i Vuornavagge under 300 år
Humans have inhabited mountainous areas in northern Sweden since the end of the last glacial period, ca 8000 B.P., and their presence has marked the landscape in various ways. Older traces include the remains of hearths and dwelling sites, but there are also remains, such as culturally modified trees (CMT's), resulting from more recent activities in forested areas. This study aimed to document how people, both indigenous Sami's and Swedish settlers, have used an area northwest of Ammarnäs in Västerbotten, during the last 300 years, and what traces their activities have left in the area. I used historical records as well as an inventory of CMT's in the area to address this aim. Historical records of Sami activity are meagre, but it is clear that the people of the Ran and Gran Sami villages utilized the area long before 1500 A.D.
Organisationskultur : Ett kritiskt granskande genom modernism, symbolism och postmodernism
Organizational culture is subject of a great debate nowadays and there is especially three schools which affairs its nature of reality; modernism, symbolism and postmodernism. This thesis is built upon a case study about the organization Idé & KunskapsCentrum, which experience various cultural issues. Observations made during visits in the organization environment forms the ground on which discussions about different perspectives are made regarding organizational culture.The thesis describes and investigates the subject of organizational culture and its relationship to human behavior in organizations. Furthermore, I discuss and analyze organizational culture from the three different perspectives, in order to present a critical view on the subject for the reader.The thesis is based upon a case study about the organization Idé & KunskapsCentrum. A qualitative research method has been conducted with data collected especially from an ethnographic study, but also via semi-structured interviews.
Den medeltida stadshamnen : Om strandområdets topografi och funktion i tre Öresundsstäder
This essay focuses on the function and development of city harbors during the middle ages in the Scanian part of Öresund. The purpose of the survey is to take a closer look at topography, development and activities on the shores in three coastal cities along the west coast of Scania. The cities that has been part of the survey are: Skanör ? Falsterbo, Malmoe and Landskrona, three cities that follows each other chronologically and that show both similarities and differences in appearance, function and urbanization.The cities of Skanör ? Falsterbo and Malmoe were important market places for the medieval Scania market with the herring fishery in focus. The cities? birth has to be looked upon in relation to these activities.
Lärares förhållningssätt till demokratisk undervisning och sin egen maktposition i undervisningsarbetet
The aim of this paper is to examine how teachers experience their possibilities to develop democratic teaching in high school and how they reflect upon their position of power within the teaching situation. Four professional high school teachers have been interviewed for the study. The theoretical perspective of the study is an intersectional view on power and a view on democratic teaching which is partly built on the high school curriculum, but mainly defined by deliberative conversations, anti-oppressive education and norm-critical education. The result of the study is focused on three themes, which were shown in the analysis of the interviews. These themes are: choices of teaching content, authority of the teacher and democratic teaching.
Vem tolkar barnets ba?sta? : En kvalitativ underso?kning av relationen mellan socialtja?nst och tingsra?tt vid va?rdnadso?verflyttningar enligt 6 kap 8 § FB
The purpose of this qualitative sociological law study is to examine the relationship between the social services and civil court to apprehend if knowledge about the child's best interest is transfered from social workers to the legal system. This have been done by investigating civil court cases concerning custody transition from biological parents to foster parents according to 6 chapter 8 paragraph in the law of parenting, built upon the legal principle of the best interests of the child. Eight cases has been examined by using a method of qualitative text analysis and categorised into five primary categories and three concepts linked to sections of the law. The material has been analysed through a sociological law perspective, social constructionist theory and attachment theory. The study shows that a variety of factors interacts when it comes to determining what?s in the best interest of the child .
Avbrottsfri Kraft med användning av ultrakondensatorer
The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.
