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.

Några aspekter på filmens tid : Ögonblicket och nuet i filmen och fotografiet
Abstract Cinematic time is the most complex of all: it is composed of public time (clock), personal time (experienced) and in addition, it can run backwards, be contingent, stored and (re)created. The present study examines some aspects of cinematic time, with special reference to the instant, the moment and the present. The strictly defined instant or moment does not exist. It is a passage between the past and the future and it is impossible to record on film or a photograph. One example is the moment of death, which is an abstraction with zero duration.
Nyinstallation av Larmsystem Till NOHAB-Diesel : Denna rapport innefattar förfarande från att konstruera och installera ett helt nytt larmsystem
Skolfartyget M/S Calmare Nyckel, som ägs och opereras av Sjöfartshögskolan i Kalmar används i utbildningssyfte av både blivande nautiker och maskinbefäl. Driften av NOHAB-dieseln, som används som generator, har varit problemfylld med ständiga och oförklarliga stopp. Det larmsystem som installerades av Oskarshamnsvarvet var högst bristfälligt. Larmsystemet var personfarligt då det var byggd på 230volt, dessutom var larmpunkterna byggda i serie med endast en stoppindikering. Avsaknaden av elritningar över systemet gjorde att bristerna i larmsystemet inte kunde felsökas. Dessutom fanns ingen indikering i kontrollrummet utan endast lokalt vid NOHAB-dieseln. Vi har gjort en nyinstallation av larmsystemet på mer personsäkra 24VDC, med samtliga larmpunkter parallella och med tillhörande indikering på panel, både lokalt vid NOHAB-dieseln samt i pulpeten för god översyn av systemet.
Co-Branding as a Tool for Strategic Brand Activation - How to Find the Ideal Partner; An Explanatory Case Study in the Fashion and Design Sector
Thesis purpose: The purpose of this study is to investigate the interdependencies within the process of partner selection in the fashion and design sector and the emanating criteria for finding the ideal co-branding partner in order to use co-branding as a strategic brand activation tool. Methodology: Multiple Case Study Theoretical perspective: Brand Building and Brand Activation, Relationship Marketing, Strategic Alliances, Affinity Partnering, Co-Branding, Consumer-Brand Relationships Empirical data: Interviews with expert consultants and company representatives (adidas, BMW, BMW MINI, Diesel, H&M, Opel, Philips, Sharp, Volkswagen) Conclusion: Partner selection depends decisively on the different co-branding aims and incorporates the crucial step when using co-branding as a tool for strategic brand activation. The co-branding aim and the corresponding partner lead to various types of relationships, which, in this study, are anthropomorphized to connect the world of marketing and branding to real life. Fashion and design brands have proven to be particularly eligible as co-branding partners for brand activation due to their innovative and trend-oriented nature..
Karaktärisering av hund TK1 för användning som tumörmarkör :
Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.
Etablering av höstraps i mellansverige :
The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden.
There are many factors that influence the outcome of the establishment, e. g.

Skedala solcellsanläggning kommer att vara Sveriges största projekterade solcellspark på4000 m2solceller och en total installerad toppeffekt på 610 kWp (maximala toppeffekten somanläggningen kan leverera). Solcellsparken projekteras åt Halmstad Energi och Miljö AB,HEM, som har en deponi under sluttäckning i Skedala. Skedala är ett samhälle nordost omHalmstad. När sluttäckningen är klar vill man använda marken till något positivt som är braför både miljö och invånare. Uppgiften i projektet har varit att projektera och beräknalönsamheten av en solcellsanläggning på området.
Etanol : ett hållbart tankande eller ett kortsiktig tänkande?
Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.
Icke glorifierande reklam inom mode
Sammanfattning Uppsatsen behandlar motbilder i reklam, icke glorifierande reklam och dess uppkomst. För att belysa den icke glorifierande reklamen och dess bakgrund har vi valt att använda fyra olika modeföretag med starkt framträdande reklam. Företagen är Benetton, Diesel, H&M och Sisley och alla fyra har använt sig av uppmärksammad reklam som bryter mot den kutym som branschen normalt använder sig av. Uppsatsen vill undersöka vilken roll som reklamsprängning haft för utvecklingen av den icke glorifierande reklamen, som blivit allt vanligare. Vidare analyserar uppsatsen ett antal reklambilder från de fyra ovan nämnda fallföretagen inom modebranschen.

RME - produktion på gårdsnivå
With a shifting world market and periodically profitability issues, Swedish farmers seekalternative ways to enhance their profitability. One interesting alternative to get a highervalue and enhance products is biodiesel, a way to improve the profitability on a farmscale.The diesel that is produced and sold, already have a mixture of 5% biodiesel, andthere is a possibility to add more biodiesel to it. By developing new engines severalengine-manufacturers now allow a mixture up to 100% biodiesel in their engines. Hencethere is a market for an increased production of biodiesel. The aim of this study were toinvestigate the possibilities and the problems related to farm-scale production ofbiodiesel, and to study the profit margin in the production.
Kompostering av organiskt avfall från Gästrikeregionen ? miljöpåverkan av olika behandlingsalternativ
In the coming years, organic food waste will be collected in the region of Gästrikland, Sweden. The collection is planned to cover the entire region by the end of year 2007. To start with, smaller amounts are being collected and transported to a central composting plant in Sala. However, a central composting plant in the region of Gästrikland is projected.The objective of this thesis is to evaluate a number of possible methods for composting of organic food wastes regarding their environmental impacts and localization.There are four scenarios for future composting of organic waste that have been evaluated. There are two that consist of membrane composting, either in Sala or in the region of Gästrikland.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Gestaltningsförslag till ny förskola på Zakrisdal
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
