Biological Production of Hydrogen and Methane: Process Evaluation and Design through Modeling

Popular Abstract in Swedish Globala klimatförändringar, nationell säkerhet och ekonomisk stabilitet är alla starka drivkrafter för utveckling av nya drivmedel. Två intressanta alternativ är vätgas och metangas producerade från förnyelsebara råvaror. Detta kan göras i biologiska processer där bakterier omvandlar socker till vätgas eller metangas. Dessa processer måste dock utvecklas och förbättras A great deal of research is being carried out on the biological production of hydrogen and methane. However, little effort has been devoted to studying the technical and economic feasibility of these processes. The main objective of the work presented in this thesis was to perform techno-economic analyses to improve our understanding of the processes by identifying the bottlenecks, and to provide

Användarperspektiv av referenshanteringssystem i en kontextuell lärandesituation

Vetenskapligt skrivande är ett viktigt moment i studentens grundutbildning. Skrivandet kräver att studenten ska ange källor på ett korrekt sätt i enlighet med en viss stil. Av erfarenhet konstateras att processen att hantera olika stilar kräver tid. Kritiskt tänkande är en grundläggande förutsättning inom vetenskapligt arbete och kräver i sig inte detaljkunskap kring olika stilars struktur. Dagens

Graphical modeling techniques and usefulness in the Model Driven Arcitechture: Which are the criteria for a “good” Computer independent model?

The Object Management Group (OMG) has presented a framework for model driven development: Model Driven Architecture (MDA). The departure point of this paper is an interest in process oriented modeling techniques relevant for a computer independent model in the MDA. We searched for the answer on the question what constitutes a “good” computer independent model (CIM). To get an answer we were using

Loanword phonology in Jahai

Jahai, a language belonging to the Northern Aslian subgroup of the Aslian branch of Austroasiatic, is spoken by a community of approximately one thousand individuals in remote parts of Perak and Kelantan, Peninsular Malaysia, and reportedly also by a small community in the adjacent part of southernmost Thailand. Jahai speakers have long been in frequent contact with speakers of neighbouring langua

Initial Survey of Concrete Structures in Swedish Harbours – A Case Study in the Port of Trelleborg

This paper is a case study on how to perform a survey of concrete structures in Swedish harbours. The purpose of the survey is to detect common damages and signs of deterioration on concrete structures in marine environment. The survey should consist of information about the structural design for the structures together with climatic conditions for the harbour in question, as well as documentation
