    • OPTIMIZATION OF BIODIESEL PRODUCTION FROM WASTE FRYING OIL OVER ALUMINA SUPPORTED CHICKEN EGGSHELL CATALYST USING EXPERIMENTAL DESIGN TOOL 

      Autor: Yusuff S., Adeyinka; Popoola T., Lekan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      An optimization of the biodiesel production from a waste frying oil via a heterogeneous transesterification was studied. This present study is also aimed at investigating the catalytic ehaviour of the alumina supported ...

    • PARTICLE MOTION OVER THE EDGE OF AN INCLINED PLANE THAT PERFORMS AXIAL MOVEMENT IN A VERTICAL LIMITING CYLINDER 

      Autor: Pylypaka F., Serhii; Klendii B., Mykola; Nesvidomin M., Viktor; Trokhaniak I., Viktor
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Differential equations of a relative material particle motion over the edge of an inclined flat ellipse that rotates around the axis of a vertical limiting cylinder have been deduced. The position of a plane relative to ...

    • PARTICULARS OF ADSORBENT REGENERATION WITH THE USE OF MICROWAVE ENERGY 

      Autor: Dobrotvorskiy , Sergey; Dobrovolska , Ludmila; Basova , Yevheniia; Aleksenko , Borys
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Energy conservation issues are acute in the world. Compressed air is widely used in the modern industrial production. The production of compressed air is a very energy-intensive process, since most of the energy, which is ...

    • THE SUGGESTIONS AS TO THE CALCULATION BEARING CAPACITY OF SANDWICH REINFORCED CONCRETE — FOAMED CONCRETE FLOOR SLABS 

      Autor: Lytvyniak , Oksana; Tashak , Myroslava
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This article presents the results of an experimental research of sandwich reinforced concrete-foamed concrete floor slabs. These floor slabs combine three different materials — normal concrete, foamed concrete and a steel ...

    • WELDING OF NITINOL BY SELECTED TECHNOLOGIES 

      Autor: Kramár , Tomáš; Tauer , Jan; Vondrouš , Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Nitinol is a perspective alloy that is difficult to weld because of its high sensitivity to heat, atmospheric gases and the NiTi phase instability. We evaluated several welding techniques with regard to their applicability ...
