Analysis of the Performance Coefficient of the Energetical Recovery of the Domestic Waste
(Universitatea "Dunărea de Jos" din Galați, 2017)
The paper critically analyses the way of defining the coefficient of
performance of the systems used for the recovery of the energy of the domestic
waste in cogeneration plants. The R1 criterion of performance of the ...
Laser Cladding of High-Speed Steel on a Steel Support
(Universitatea "Dunărea de Jos" din Galați, 2005)

bath by CO2 continuous wave laser connected to x-y-z coordinate table was ...
Aspects Regarding the Widia Plates Behaviour Covered with TiN During the Cutting Process
(Universitatea "Dunărea de Jos" din Galați, 2005)
The microscopic property that depends on the interfacial structure and on
the tension to which the interface is submitted is called adherence. The strong
connection in the interfacial area, low tension gradients, the ...
