A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer.Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok.Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå.Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare.Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation. .

Literature is an important part of the daily activity in preschool and it is also a powerful tool for reinforcing different norms.The purpose of this study is to explore, through qualitative interviews, for what purpose pedagogues in preschool use literature in their daily activity and what needs these pedagogues see for non-heteronormativity literature. The study also relates the needs that pedagogues see with the basic values presented in the Swedish National Curriculum for preschool.Literature is used in preschool for a wide range of purposes including; enriching the language, getting familiarized with the written language, show diversity, reinforce norms on how to be a good friend, as a starting-point for discussion, working with a theme or to have a fun time.The needs that the pedagogues see for non-heteronormativity literature can be divided in to three categories namely there is always a need, there is only a need when somebody requires that kind of literature to identify themselves with or there is only a need when somebody is being discriminated because of not belonging to the heteronorm.The need for non-heteronormativity literature being there always corresponds with the basic values in the Swedish National Curriculum for preschool and the recommendation that the basic values are visible in the daily activity of the preschool. The other needs doesn?t correspond with this, but it matches other parts of the Swedish National Curriculum for preschool..

ABSTRACT This essay is about traffic analysis of Web servers. The purpose is to investigate if companies analyse the traffic on the Web server and if they use this information to create more than simple statistic reports. The questions that we will answer are the following: ? How common is traffic analysis on the Web server among companies? ? Is the Web administrator limited in analysing the Web traffic, if the company has the website on a Web hotel? ? Does the company uses the results they get from analysing the traffic on the Web server for updates and changes on the Web page? To answer these questions we made a questionnaire investigation by telephone interviewing the companies? webmasters. The extent of the investigation was 20 companies in Blekinge.

The purpose of this master?s thesis is to examine the activity at the library and preschool at Kristineberg (a part of the town of Borås) and its underlying approach. How do the activities agree with the ideological attitudes of the 1970s? To answer these questions I have carried out a case study based on qualitative interviews. The theoretical background includes ideas of the library, the community center and the cultural activity at the library.

The kitchen is one of the most important rooms in our homes. It is a place for social engagements, meetings between people and activity. How the kitchen looks today is a concept sprung from the Swedish kitchen standard of 1952. Eventhou this standard no longer exists it is a model of how kitchens are designed today. The kitchens most often sold today come from one of four major kitchen manufacturers in Sweden.My thesis investiges an alternative kitchen concept.

The knowledge development regarding in-store marketing has shown that influencing a consumer in a store setting is a powerful tool to change the consumer?s buying patterns. However, the store as a marketing channel lacks, in many ways, conducted academic research and according to marketing theory investments into in-store marketing tend to be taken without advanced marketing consideration. As a consequence, we have chosen to generate new insights into the field of in-store marketing by studying in-store demonstrations both from a behavioral and a mental dimension. Furthermore, we have also chosen to study how different consumers with different degree of loyalty and buying patterns are influenced by an in-store demonstration.This study aimed to obtain a better understanding of in-store demonstrations through breaking down the demonstration into its core elements and from these elements construct different types of demonstrations.

AbstractThe purpose of this study is to analyse the reading- and writing-approaches: the LTG-method and the whole language-theory. The attention is to perform a comparative literate-study to distinguish their similarities and differences, and examine which one of the approaches that is most clearly anchored in the syllabus of the subject Swedish. The starting-point of the study is the questions: Which similarities respectively differences have the LTG-method and the whole language-theory? Which one of these theories is most clearly anchored in the syllabus of the subject Swedish? The study has shown that both the whole language-theory and the LTG-method can anchor in the syllabus for Swedish. However the whole language-theory has stronger hold in the syllabus, as the whole language emphasises the meaning of literature for reading- and writing-learning, and considers the pupils reflection during their learning-process and conquered knowledge-goal.

This paper is about basic set theory and cardinalities for infinite sets. One of the results are that the line R and the plane R2 contains exactly the same number of points. Because of that the set theory is described with a formal language this the paper has an appendix about formal languages..

Syftet med vår studie är att finna faktorer till spridningen av kalkylmodellerna Activity-based costing (ABC), Target costing (TC) och Kaizen costing (KC). Detta gör vi genom att använda oss av kvalitativ ansats och genomföra intervjuer vid sex tillverkande företag. Vi kan se influenser av spridningen av modellerna ABC, TC och KC i studiens företag. Det har visat sig att företagen tillämpar ?traditionell? produktkalkylering med inspiration av ABC-modellen.

This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.

Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis. TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.

SUMMARYThe riding school horse is the base for the riding school. Riding schools are looking for a suitable horse that meets their demands for exterior, age, education, temperament, price and sustainability. Many different aspects may define the sustainability of the riding school horse; of them is how long life the riding school horse has in riding school activity. Previous studies have shown that the riding schools requirements are 8-12 years life span in the riding school.The purpose of this study was to describe the Swedish riding school horse life span in riding schools and at what age the riding school horses were recruited, disposed and the reasons for disposal. Information about the riding school horse life span in riding schools and reasons for disposal can provide important understanding regarding the importance of health for the riding school horse, riding school economy and profitability in the riding school.
