    • Replacing Natural Gas by Biogas — Determining the Bacterial Contamination of Biogas by PCR 

      Autor: Čermáková , Jiřina; Mrázek , Jakub; Fliegerová , Kateřina; Tenkrát , Daniel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      A promising way of using biogas is to upgrade it to natural gas, which is referred to as Substitute Natural Gas (SNG) or biomethane. Biomethane, or biogas, is produced by biological processes of harnessing the ability of ...

    • Strontium As a Structure Modifier for Non-binary Al–Si Alloy 

      Autor: Stunová , Barbora Bryksí
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper presents a study of the influence on the structure of AlSi10Mg alloy when 400 ppm of strontium is added. Not only changes in the morphology of eutectic silicon, but in particular changes in the morphology of the ...

    • The Effect of Temperature on the Gasification Process 

      Autor: Baláš , Marek; Lisý , Martin; Štelcl , Ota
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      Gasification is a technology that uses fuel to produce power and heat. This technology is also suitable for biomass conversion. Biomass is a renewable energy source that is being developed to diversify the energy mix, so ...

    • The Simulation of the Influence of Water Remnants on a Hot Rolled Plate after Cooling 

      Autor: Zahradník , Radek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In situations when a sheet metal plate of large dimensions is rolled, water remnants from cooling can be observed on the upper side of the plate. This paper focuses on deformations of a hot rolled sheet metal plate that ...
