Since some years Linköping has invested in biogas production, mainly from offal's, residuals from food industry and manure. The municipality goes for biogas in the local traffic and in all transportation. It is also possible for private car owners to run their cars on biogas. The purpose of this essay is to perform a cost-benefit analysis and examine if the project has been beneficial from a social point of view. The effects have been identified, measured and monetarily valued. The essay is limited to include the year of 2006 only.

The development of solar photovoltaic (PV) is increasing,with declining module prices and with a strongenvironmental profile. Policies are developed around theworld to achieve the targets set for renewable energy.In Helsingborg, the local power company Öresundskraft isworking with solar PV to achieve the goals of the city.With their vision: - Energy for a Better World and Powerfor the Region, their work with developing the local solarPV market is continuing and the next step is to create asolar PV policy. Today their offer is 1 SEK/kWh for theexcess electricity delivered to the grid.It turns out that compensating the customer is a vitalpolicy and it has to be dynamic to follow the decisions ofpolitics. The same survey shows indeed, thatenvironmental and technical part is of interest. Solar PVwill be supported locally to act on environmentalsustainability and locally produced electricity and withthis Öresundskrafts vision will be achieved..

Ledarskap är idag ett högst aktuellt ämne. Företag etablerar sig i andra delar av världen och globaliseringen gör att organisationer måste integrera med andra kulturer än sin egen. Ledarskap blir då en nyckelkomponent och ett konkurrensmedel. I vår uppsats vill vi granska fenomenet ledarskap i en annan kulturell kontext än vår egen. Med hjälp av ett MFS-stipendium från Sida fick vi möjlighet att åka till Sihanoukville, Kambodja för att att göra en undersökning om ledarskap och kultur.

Den globala bilindustrin har under de senaste decennierna genomgått betydande förändringar, vilketskapat ett allt hårdare marknadsklimat. Detta har medfört att strategisk positionering i synnerhet blivitallt viktigare för aktörerna på marknaden. Försäljningen av Volvo Car Corporation och SaabAutomobile till Ford Motor Company samt General Motors under 1990-talet ansågs därför som ennödvändig åtgärd för att säkerställa Saabs och Volvos fortlevnad. Perioden under amerikansk ägandehar emellertid visat sig tuff och knappt ett decennium senare stod bilindustrin för sin kanske störstautmaning någonsin i sviterna av en extrem global lågkonjunktur. General Motor och Ford MotorCompany drabbades hårt, vilket ledde till att det inte längre ansågs ekonomiskt hållbart att behållaförlusttyngda bilmärken som Saab och Volvo.

Sweden has an active and growing culture of feminist comic book artists that use comedy as a mean of disseminating political ideas and critic. In this essay I do a reparative reading of Sara Granér?s comic book All I Want for Christmas is planekonomi in order to find out if it advocates alternative orders and/or ways of expression. By exploring what the comic book does to me as a reader and how, using the term ?skev? ? a hybrid of queer that examines normativity not strictly tied to sexuality ? and gulesque theory ? a mix of feminism, cuteness, the grotesque and riot grrrl ?, I show that the comic book, through the use of comedy, works as a trojan My Little Pony, reclaiming the girly franchise, while challenging several so-called dichotomies, such as: femininity/masculinity; youth/adult; high art/kitsch.

Detta arbete undersöker ACT och ställer frågan om terapiformen kan betraktas som en existentiell beteendeterapi. Ett material bestående av 53 vetenskapliga artiklar undersöktes med en tematisk innehållsanalys för att få en bred och aktuell bild av ACT i avseende på teori, praxis och människosyn. Resultatet sattes in i en psykologihistorisk kontext i allmänhet och en beteendepsykologiskt kontext i synnerhet. Det som talar emot ACT som en existentiell beteendeterapi är främst bristen på oppositionella inslag och kritik av den vetenskapliga normen. I andra vågskålen placerar resultatet det holistiska perspektivet samt synen på människan som ickedeterminerad.

The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst.In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren?t allowed to receive more organic waste.

The aim of this literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

I denna kandidatuppsats avlägsnas organiska föroreningar från vatten genom användning av textilier, vars yta belagts med nanopartiklar utav ämnet titandioxid. När titandioxid belyses med UV-strålning sker en fotokatalytisk reaktion, vilket i sin tur bryter ned bland annat bakterier och organiska färgämnen. I hopp om att finna ultimat vidhäftning mot textil passande titandioxid har olika typer av beläggningar studerats; akrylbaserade, sol-gel och slutligen en hybrid. Dessutom har fem olika konstruktioner av textila bindningar jämförts i syfte att undersöka dess påverkan på den fotokatalytiska effekten. Förorenade vatten är ett stort problem, både i utvecklingsländer och i industriella sammanhang.

De senaste åren har marknaden för surfplattor växt massivt samtidigt som Smart-TV?s har kommit fram som en ny produktkategori. Detta arbete är en undersökningen i hur surfplattor tillsammans med Smart-TV kan användas för att skapa en bättre upplevelse för användaren. För detta utvecklades en applikation på en LG Smart TV som sammankopplades med en surfplatta för att visa information om ett pokerspel. Sedan utfördes en undersökning med intervjuer där hybridapplikationen jämfördes gentemot att bara spela på surfplattan.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.
