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.

This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.

Aim: The aim of the study was to illustrate the relation within palliative care from nurse- patient perspective. Method: The study is a literature review where ten articles were analysed with qualitative content analysis. Results: The findings showed that knowledge, communication, continuity, silence and availability were the most important thing for the nurse in the relationship.

The aim with this study was to investigate how a few teachers in Swedish, at upper secondary school, are using computers in their teaching, and what approach they have towards using computers in teaching. A qualitative study has been made to accive a result, on this matter, were five currently teaching teachers in Swedish, at different upper secondary schools, have been intervjued. The teachers answered questions concerning how and in what speciefic fields of study they use computers, the computer program and -tools they are using and what benefits and disadvantiges they see with computers in teaching. They also answered questions concerning the availability of computers at the schools which they are working. The study showed that the way teachers are using computers in their teaching, and the amount they are using them varied between the teachers; but all are using computers mainly with the purpose to write texts and to search for information. All teachers also had in common that they are using computers not as frequently and in a different way when grammar is concerned. It appered that the teachers were mainly positive to use computers in their teaching, even if some teachers acknowleadged more disadvantiges than the others.

Den här avhandlingen behandlar design av användargränssnittet till ett gaslarm, utformat för andningsvård med medicinsk luft och oxygen under ambulanstransporter. Arbetet har utgått ifrån att ambulanssjukvårdare påtalat avsaknad möjlighet för enkel övervakning av gasflödet från luft- och oxygenflaskorna. Det innebär problem då de inte upptäcker förrän i efterhand om behandlingar inte fullföljs, på grund av att gasflaskan är tom eller felaktigt installerad. Vid närmare kontroll av situationen insågs även att påminnande behövs angående påslaget gasflöde, på grund av att ambulanssjukvårdarna också kan glömma stänga det efter användningen. Frågeställningen har således först handlat om att fastställa behovet av ett gaslarm, att det verkligen behövs och varför.

Most of the stoma-operated persons must work themselves through difficult feelings. The task for the nurse is to deliver a care that promotes as much independence as possible. The aim of this literature review was to illuminate how the self-care agencies affect the well-being for the persons who are operated for stoma. A systematic literature study was done based on eleven scientific studies. Three categories, which describe how self-care agencies affect the physical, psychological and social well-being, are presented in the result.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

The purpose of this paper is to find out if there are any simple solutions to attract an increased use of public transportation in a smaller town in Sweden. Simple solutions are measures that can be taken within the current budget, and which do not require large investments and extensive political decisions. In order to search for possible solutions I needed to find out which factors and attitudes that determine why people choose public transportation and peoples? traveling habit. I have made a survey study of satisfaction and attitudes among the consumers of a public transportation company in Växjö; Länstrafken Kronoberg.

Electronic availability of information resources has increasingly become an important part of academic libraries everyday vocation. This is a fact that puts impetus on the libraries to know more about the way in which electronic information is being dispersed and handled. This thesis aims to comparatively evaluate Uppsala university library´s own metadata system Summon with the publicly available equivalent Google scholar. The evaluation is based on Péter Jacsó´s theories on database evaluation which concretely puts focus on Summon and Google scholar via the use and application of ten different criteria. The uses of precision and relevance criteria were also implemented as additional evaluation tools.

Background: Relatives are those persons who are closest to the patient, regardless of relationship and included into the patient´s life world. When a person is in a palliative stage this affects not only the patient but also the relatives, as it implies such a big change in life for all. The nurse has an important role for both the patient and the relatives. Aim: The aim is to highlight the relative´s needs of support for palliative care. Method: A literature review based on previous research. Ten articles were found, nine with a qualitative approach and one with both qualitative and quantitative approach. Results: The analysis resulted in six themes, these were the result of the study. The six themes were, ?to be seen an confirmed?, ?good communication?, ?continuous information?, ?availability and continuity?, ?to participate? and ?to share responsibility with the staff?. Conclusion: As a nurse we come in contact with relatives of patients in a palliative setting in any form.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Our consumption habits are today under development and alteration. The market for mobile commerce is increasing, as well as the use of social networks with mobile devices. This relatively new approach to online shopping requires that retailers adjust to new strategies related to trust issues. The purpose of this study is to examine how social networks affect the establishment of trust between retailers and customers in mobile commerce. We investigate what kind of strategies retailers apply in order for consumers to gain trust in the mobile environment.

The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.
