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.

Jämförande livscykelinventering
This bachelor?s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.
Kommunala bolag och demokratin - Om bolagiseringstrendens inverkan på folkstyret.
Kulturvårdscentrum was a project that had great significance for local folklore societies in Bohuslän.Bohusläns museum was i charge of the project that lasted from 1987 until about 2001 when most ofthe original staff have retired. The staff was mainly recruited from a large shipyard, Uddevallavarvet,at it's closure due to recession. Financing was largely made by the government to help outthose unemployed who otherwise should have a hard time finding a new job. At start there was about25 employees who where trained for one year by staff from Swedish museums, conservation studios,and teachers the university. The education was aimed at serving local folklore societies, and dealingwith their special problems.
en litteraturstudie om musikterapi som behandlingsform : hur musikterapi kan stimulera och utveckla motoriken hos gravt funktionshindrade barn och ungdomar med retts syndrom och cp skada
University of VäxjöSchool of Social SciencesBachelor Thesis in Political ScienceTitle: ?Sverigedemokraternas valframgångar 2006 ? En ulv i fårakläder??Author: Emma Haraldsson and Åsa NeuschützTutor: Emil UddhammarThe aim of this study is to explain Sverigedemokraterna?s electoral success in 2006 and the essay assumes that some form of change has occurred. To study this change two hypotheses have been constructed. The first hypothesis concerns the change within Sverigedemokraterna and the second hypothesis concerns the change of the Swedish voters attitudes.Kirchheimers catch-all theory is used to explain the change in Sverigedemokraterna. The catch-all theory states that parties have to change their structure to maximise the number of votes.

Companies that manufacture magnetic separators were contacted.
Patienters upplevelser och attityder till tandhygienistbehandling, samt ett reliabilitetstest av mätinstrumenten Corah Dental Anxiety Scale och Dental Hygienist Beliefs Survey
The aim of the study was to examine experiences and attitudes to dental hygienist treatment in a group of patients by using the assessment tools Corah Dental Anxiety Scale (DAS) and Dental Hygienist Beliefs Survey (DHBS) at the dental hygienist clinic, the university of Kristianstad. Another aim of the study was to test the reliability of the assessment tools. Methods: Fifteen respondents answered the two questionnaires at two different occasions before dental hygienist treatment. The results showed that nine respondents reported that they are absolutely calm when their dental hygienist is going to remove tartar, while six are a little bit worried or tensed. The categories ethics, communication, trust and control in DHBS had a positive agreement (mean value 1.1 and 1.2).
Patienters uppfattning av ronden : integritet, information och delaktighet
ABSTRACT Background: The ward round is a collaboration between nurse, doctor and patient. A good collaboration and communication is essential to their interrelation. Aim: The aim of this study was to investigate patients' comprehension in regard to integrity, information and participation during round. We also looked at differences about comprehension between men and women.  Methods: A questionnaire was answered by 34 patients in three wards at the University hospital in Uppsala. Results: The patients believed they could talk openly ?quite well? but they experienced it ?sometimes? disturbing to talk openly if other patients were in the room.
Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft
The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
Ett författarskap i akademins gränsland : Stallmästare Johan Leven Ekelunds efterlämnade manuskript
Uppsala University Library owns eight volumes of manuscripts attributed to the academy equerry Johan Leven Ekelund (c.1701?1775). In this thesis, I apply methods from the field of material culture studies in order to establish which of the volumes that formed the donation from Leven to the library mentioned in his will. By mapping certain markers such as places, names and dates I am able to identify to some extent where Leven gained his practical skills and which writers influenced him. By analysing the texts, I draw the conclusion that the manuscripts can be divided into groups aimed for different audiences.

Kvalitetsledningssystem enligt ISO 9001 : Produktionsprocessen
This report is the result of a thesis work done at the Department of Engineering Sciences, Uppsala University, and includes 15 ECTS points. The work has been performed at Företag A, a company specializing in electronics whose major product has become a sophisticated tool used by authorities across northern Europe. Företag A has initiated a quality management system according to the criteria set by ISO 9001. Following demands from customers, Company A has now decided to also start working towards a certification according to SS-EN ISO 9001:2008, this work is the foundation for the thesis work. The thesis work has been limited to the production process and the aim has been to enable this process to be certified according to ISO 9001:2008. The work has been performed by analyzing the existing quality management system and the requirements for each process included, whereby the gap between the current and the target state has been mapped. Suggestions have then been made on how this gap can be filled, some of these suggestions have also been carried out during the thesis work. The conclusions drawn are that quality management does not have to be complicated, but quickly becomes so when the complexity of the processes increases.

Vad gör egentligen en landskapsarkitekt? : en studie av hur yrkesrollen framställs och upplevs
This is a thesis written at the Swedish University of Agriculture inAlnarp within the landscape architecture education. The essay dealswith the landscape architect's professional identity and how it isdescribed in different contexts along with how it is perceived byprofessional landscape architects.Misunderstandings and preconceptions concerning the landscapearchitect's professional identity is common, both within and outsidethe branch of industry that includes the vocation. This raises problemswithin the industry and for the individual landscape architect. To findout if the root of the problems lies in available descriptions of theoccupation a study has been made. The study includes how thelandscape architect is defined in easily accessible information fromthe internet and in literature as well as in industry-orientedinformation such as dissertations and information from SverigesArkitekter (the Swedish Architects).
Bygelstolpar : Kraft- och spänningsanalys av bygelstolpar tillhörande Bruks mobila hugg 805 CT
This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.
