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.

This is a bachelor thesis, written at the business studies institute, Uppsala Unviersity, exploring how digitalization has affected the Swedish book industry. This is done by studying how the introduction of the e-book has changed the way the publishers work and what problems and opportunities arise with the new way to publish and consume books. The technology optimists, that existed around the turn of the millennium, when the e-book came, made predictions along the lines of the physical book having ceased to exist within five to ten years. But the physical paper books do very much still exist, so haven?t the change happened as predicted? The purpose of this thesis is as follows: How has introduction of the e-book affected the relationship between the Swedish publishers and the book as a whole? This means that we consider the book as a concept, as a resource or product, and study how a change in this product affect publishers.The theoretical framework used is basically classical network theory.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

The purpose of this essay was to find out how leaders in micro service firms practice HRM and identify which HRM related problems they experience in their leadership. A case study consisting two cases was carried out. The study has shown that leaders in micro service firms use a highly personalised, informal management and involve their employees in the firm?s development. The findings were that leaders of micro service firms do not have any theoretical knowledge of HRM practises because of lack of education.

As break downs of production transformers are costly and often result in long outages it is essential for reliability of operation that the transformers are manufactured to be robust. The aim of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement.The investigation has been conducted in three stages. In the first stage a definition of the term robust was developed in consultation with the client Vattenfall Vattenkraft.

It is important that companies knows how to handle a complaint when they receive one from a customer. This information could the company take care of and use when they develop new services. Furthermore a good complain handling leads to satisfied and loyal customers which increases the revenue for the company. We have examined how SAS handle their internal information process and if this process affects the information and in that case how. The study is performed with a qualitative method, based on deep interviews.

En ökad tillväxt inom tjänstesektorn och företagens strävan efter att bli mer konkurrenskraftiga har bidragit till högre användning av ett betydelsefullt verktyg i affärsvärlden: outsourcing. Outsourcing gör det möjligt för företag att köpa in tjänster som saknas internt. Genom att ingå i ett samarbete tillsammans med externa leverantörer kan företaget, genom att köpa externa aktiviteter, stärka delar av sin verksamhet som tidigare varit bristfälliga. Dagens samhälle präglas av företag som ständigt strävar efter att höja sin effektivisering och minska sina kostnader. Det har i sin tur medfört att outsourcingen fått en stor inverkan på tjänster, till exempel marknadsföring.

Aim: The aim of this study was to investigate how women who have incurred ACL injury for more than 10 years ago, feel that the injury affects them today.Method: A qualitative semi-structured interview survey with five women who 10- 28 years ago incurred the anterior cruciate ligament injuries when playing handball or soccer has been performed. The study has been inspired by a phenomenological concept of science, mainly by life-world concept. Data were analyzed using qualitative content analysis.Main result: Some informants have experienced severe loss of physical ability in both daily living situations and in training, while others did not appreciably felt impacted in daily living and experienced great opportunities for physical activity. Limitations which emerged were restrictions in movement, joint stiffness, pain, swelling, and crepitations that led to the loss of physical ability. One respondent had been diagnosed with advanced osteoarthritis.

Abstract: In this study, I have searched for answers to whether teachers use pictures in their teaching with the purpose of making education easier. Can we use the pictures with a pedagogic purpose? In this study, I have interviewed middle-school teachers concerning this subject.My results show that teachers actually use pictures in order to make the education easier for pupils but they do not do it very often. They think that they do not have the time to look for the good pictures that go with their subject and that they can show in the classroom. They also think that the pictures in the textbooks are good enough and they do not discuss the pictures very much.

Begreppet Human Resource Management, d.v.s. ledning av de mänskliga resurserna, har de senaste åren vuxit sig större. Detta beror bl.a. på att medvetenheten kring organisationer och hur man får anställda att öka produktiviteten har blivit större. Idag vet vi att de psykosociala faktorerna på en arbetsplats är av stor vikt för att få en ökad produktivitet och effektivitet.

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units.

The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.
