With today’s growing awareness of human caused climate changes there is a big interest to replace fossil fuels with renewable fuel sources, such as biomass fuels. For power production biomass are traditionally combusted in small scale facilities which uses a steam cycle. The electrical efficiencies for such facilities are relatively low. By gasifying the solid biomass to syngas it can be used for

In this study a dynamic model of a solid oxide fuel cell system has been developed. The work has been conducted in cooperation with Modelon AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. The objective of the study is to investigate the suitability of the Mode

AAK is a company that refines vegetable oils and one of the factories is in the town Karlshamn in Sweden. At AAK Karlshamn process steam and electricity is generated in a cogeneration facility whit several boilers and a back pressure turbine. To continue whit

This thesis is a risk assessment of the risk related to ingestion of heavy metals via peaches irrigated with treated wastewater. The studied heavy metals were Cadmium (Cd), Lead (Pb), Zinc (Zn) and Cupper (Cu). The thesis is founded on a case study performed on a peach field in Ouardanine, Tunisia. Analysis of the heavy metal content in the treated wastewater used for irrigation was conducted as w

The aim of this project is to investigate whether scuba diving equipment can be made safer and more attractive for new divers. The thesis shows that most accidents occur because of poor equipment checks and misused equipment. This problem is the main concern of the thesis. The resulting product, 4° (Four Degrees), is a buoyancy compensating vest with a focus on safer diving, non-complex appearance

Syfte: Syftet med denna studie är att empiriskt använda Sarasvathys ramverk på tre utvalda företag och deras etableringsprocess på den svenska dryckesmarknaden. Metod: Vi har valt att använda oss av en abduktiv synvinkel i vår studie. Den valda undersökningsmetoden är kvalitativ där primärdata samlats in från de intervjuer vi genomfört med grundarna för varje företag. Sekundärdatan vi använt i den

The main factors driving the development of modern means of payment is people's attitudes, the integrity aspect and international influence. People have an instinctive belief that change is synonymous with detereoration. Realizing a cashless society requires a change in the willingness to change and improve. For the development of new payment methods it will eventually be necessary for increas

Syfte: Syftet med denna studie är att jämföra ISO 26000 med etablerade CSR-teorier och genom det komma fram till en ny modell som kan hjälpa företag i sitt arbete med CSR. Metod: Vi har utfört en kvalitativ forskningsmetod där vi utgått från en induktiv ansats genom att vi har samlat in data och utifrån empirin försökt skapa egen teori. Uppsatsen grundar sig främst på det senaste utkastet av ISO 2

Denna uppsats är en cost-benefit analys av Systembolaget som detaljhandelsmonopol, som också inkluderar alkoholskatterna. Dagens situation är den att Systembolaget har detaljhandelsmonopol på starköl, vin och spritdrycker, öl säljs i vanliga livsmedelsbutiker. Alkoholpriset består av fyra komponenter; alkoholskatt, moms, Systembolagets handelsmarginal och leverantörens pris. För hög alkoholkonsumt

Uganda has fertile soils and climatic conditions well suited for cotton production. The country has a competitive advantage in the good intrinsic quality of its cotton, the cheap labour and the fact that cotton is handpicked. There is a ready market for the cotton once it is harvested and there are many areas of use, such as textile, medical supplies, cooking oil, soap and animal feed. In spite of
