      The success of vegetal oils is related to their biodegradability and reduced toxicity but a wide use is limited by their insufficient stability in time. Biodegradable oils have ecological advantages, being comparable or ...

    • Viscosity of Amorphous Molecular Substances 

      Diaconescu, Emanuel; Zegrean, Vlad Flaviu; Onciul Miron, Oana (Universitatea ”Dunărea de Jos” din Galați, 2008)
      Because the great majority of flow units in a liquid behave instantaneously in a solid-like manner, rheological properties of molecular liquids subjected to high pressures may be measured by using corresponding molecular ...

    • Wear Behaviour of the AL7175 Alloy under Different Bulk Stress States 

      Buciumeanu, Mihaela; Miranda, A.S; Silva, F.S (Universitatea ”Dunărea de Jos” din Galați, 2008)
      In what concerns the stresses involved in the process, most wear tests (namely those in the pin on disc and the pin on plate configurations) are usually solely concerned with the stress state in the contact originated by ...
