Deaktivering av metanisering katalysatorer

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.

Gruva eller renar? : En deliberativ analys av deltagande i beslutsprocessen vid en gruvetablering i Storumans kommun

This thesis examines the conditions for participation in the decision making process of a possible mine establishment in Storuman municipality in the north of Sweden. This is done through a case study where the main actors are the mining company Nickel Mountain AB, the municipality Storuman and the Sami village Vapsten. As a theoretical framework Cecilia Eriksson?s division of democratic theories is used as a starting point. Methods as described in deliberative democratic theory, such as discussion by effected community members, are seen as a method within the participatory democratic tradition, not a theory of its own.

Metod för analys av elförbrukning i hushåll

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

"Vi ska gå bra och må bra"

Working with health-management has become something most organizations would describe as essential for being legitimate today. The aim of this thesis is to investigate how this subject is handled in an existing company and how this work is percieved by the employees in the organization. Due to the fact that limited research has been conducted on this issue, we see this thesis as a potential for increasing the understanding of how health management is articulated in practice. Our results show that health management in our studied organization is far reaching in comparison with most organizations, but has room for improvement according to the Integral Theory. The consequence of differences in perceptions between management and employees could result in that health management does not become an integral part of the company and its daily operations to the potential extent..

Invadörer på svenska spelmarknaden-En statligt reglerad marknads ökade konkurrens från webbaserade företag

In Sweden we have a regulated gambling market which means that there are three gambling companies who are operating under the supervision of the Swedish state. These companies have exclusive rights to the Swedish market, divided between them. AB Svenska Spel is one of them and they control all gambling concerning sporting events and the four casinos in Stockholm, Gothenburg, Malmö and Sundsvall. However, since a few years back several Internet-based companies have entered the Swedish market and the competition has become even fiercer in the last years. Due to numerous marketing restrictions the Internet companies have been forced to find new ways to strengthen their brand.

MeasureApp : Utveckling av en Android-applikation fo?r ma?tning och kartvisning med hja?lp av GPS

The objective of this project was to develop an application for mobile phones using the Android operating system. The main goal was, with the help of GPS, to pinpoint locations, measure distance traveled and illustrate the progress on a map. Functionalities for just showing the map, fetching addresses and saving to a database was also implemented. The result of the work was a proper application, called MeasureApp, that fulfills the goals set in the planning stages of the project. MeasureApp can be used to measure distances where accuracy is not a main factor, i.e walks or runs.

Private equity - nyckeltalsförändringar; En studie om hur portföljbolag förändras efter ett uppköp

In this paper we investigate 67 Swedish buyouts in the manufacturing and retailing sector between the years 2004-2012. The purpose is to measure changes in a set of financial key ratios to see if private equity firms are able to improve performance in their portfolio companies compared to a peer group consisting of other firms within the same industries. Furthermore, we examine if there is a difference in the change of the financial key ratios between private equity-owned firms in the two sectors. The key results are that the private equity owned firms have not outperformed their peers with respect to the chosen key ratios. We also conclude that there is no significant difference in the change of the financial key ratios between private equity-owned firms in the two sectors..

Finansiella nyckeltalens samspel som investeringsstrategi : En kombinationsmodell för att uppnå riskjusterad överavkastning

This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

Utveckling av modulbaserat inredningsystem för klädförvaring

Det här projektet har syftat till att utreda hur en vald målgrupp förvarar och vill förvara sina kläder samt hur ett klädförvaringssystem för denna målgrupp bör vara utformat för att uppfylla användarens krav och önskemål. Funktionalitet, användarvänlighet och ergonomi är begrepp som genomsyrat projektet från start till mål och målgruppen definierades i projektets början. Utbudet av klädförvaringssystem för dressing room i Sverige är idag väldigt begränsad. Kökstillverkaren Kvänum Kök AB har fått många förfrågningar om klädförvaringssystem som håller samma höga klass och exklusivitet som deras kök. Denna kategori, inredning för dressing room, lämnar ett stort hål i det annars så välfyllda utbudet av förvaringssystem på den svenska marknaden.

Installationsgränssnitt under Linux och Windows XP utifrån ISO 9241

This thesis investigates how different Linux-distributions installation interface relate to the ISO 9241 standard, parts 12 and 13, and how they relate to the installation interface of Windows XP, with the hypothesis: "There is a Linux-distribution whose installation interface according to applicable HCIrecommendations is equivalent to that of Windows XP." With the checklists provided by ISO 9241 an empirical study has been made, and so comparable measurements of how well the Linux-distributions and Windows XP follows the recommendations of the standard was obtained. By comparing the results from the tests similarities and differences between the installation interfaces can be deducted. As the result and the conclusion shows there are Linux-distributions whose installation interface, according to the applicable HCI-recommendations, are equivalent to that of Windows XP..

En bra plats för lek : kreativ och tillgänglig lekplats i Hedemora

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Algoritmer för objektdetektering i SAR och IR-bilder

The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.

Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.
