    • On Dynamics of Bucket Wheel Excavators with Radial Digging 

      Debeleac, Carmen (Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
      The paper presents the influence of some structural and operating parameters on external load characteristics caused by resistances to reclaiming at bucket wheel in the radial digging process.
    • Second Law Analysis of a Furnace for Metal Heating 

      Pană, Daniela (Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
      The industry represents an important sector of the final energy consumption and despite the effort made so far, energy saving potential still remains in this sector. This paper presents an example of energy efficiency ...
    • Some Physical Changes in Extra Virgin Rapeseed Oil after the Process 

      Şolea, Liviu Cătălin; Ştefănescu, Ioan; Zgherea, Gheorghe; Creţu, Romică (Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
      The aim of this study is the viscosity’s evolution depending on the temperature and the shear rate and the analysis at the transmittance spectra of the oxidized rapeseed oil. Rapeseed oil was oxidized at the temperatures ...
    • Spectrophotometric and Rheological Studies on Oxidized Soybean Oils 

      Şolea, Liviu Cătălin; Creţu, Romică (Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
      This paper presents a rheological and spectrophotometric study of oxidized and nonoxidized soybean oils at 100, 110 and 120°C temperatures. The oxidation periods of time were 5 hours and 10 hours. Changes of the oxidized ...
    • The Calculation Procedure of Experimental Sonic Generator with Two Resonators Designed for Water Treatment Processes 

      Cîrnu, Carmen-Liliana; Șerban, Anca (Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
      The design parameters such as nozzle slot, generator’s slot, resonance chamber diameter, resonator neck length, inlet port diameter are required to determine the optimal operating parameters while using the sonic generator ...
