2. Produktion av biofilm med MRSA, MRSP eller Campylobacter jejuni, samt hur olika desinfektionsmedel påverkar den
University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public HealthAbstract : I denna studie ingick såväl produktion av biofilm i en statisk modell med mikrotiterplattor där biofilmen fick växa ostört i 5 dagar i inkubationsskåp i 30 °C, samt en mer dynamisk modell. I den dynamiska modellen ingick vattenledningsrör där buljong och bakterier växt i inkubationsskåp i 30 °C i 5 dagar för att sedan stå i rumstemperatur i ytterligare 5 dagar med daglig skakning i en timme, samt att buljong byttes ut vid dag 5 och nya bakterier tillsattes dag 7.

3. Small-scale biogas : A techno-economic comparison of Internal Combustion Engines, Micro Gas Turbines and Stirling Engines
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Gas driven power generation is expected to increase in the near future due to significantly lesser environmental impact than oppose to conventional fuels like coal and oil. Today, Natural Gas (NG) is the dominant product on the market and biogas, which originates from degradable organic waste, has not reached its full market potential due to bottlenecks in utilization.

4. InAs and high-k oxides, a scanning tunnelling study of their interfaces
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. READ MORE

5. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy
University essay from KTH/MaterialvetenskapAbstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE
