Influence Pressure and Size Particle to Extraction by CO2
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
Supercritical fluid extraction (SFE) is an efficient extraction technique for the
separation of various organic compounds from herbs, or more generally, from plant
materials. These proporties of SFE make the products ...
Structural Characteristics in Cobalt Based Alloys
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
In the present paper there are presented results of investigations on samples of
partially removable denture made of cobalt base alloys (Co-Cr-Mo) regarding
specific structural analysis: determination of structural phases ...
Hydrodynamic Aspects on EAF's Smelt Metallic Mirror
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
Using the Physical and Mathematical knowledge, a new approach to EAF bath’s
hydrodynamic aspects is proposed to be developed in this paper. Experimental
results and a mathematical equation package have been concluded ...
The Influence of Cold Rolling on the Mechanical Characteristics for Drawing Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper presents the changes of the mechanical and technological
characteristics of steel for deep drawing, cold rolled and recrystallization heat
treated. The research was conducted on samples taken from cold rolled ...
Contribution in the Domain of the Contact Stresses Between Cylinders of Cold Rolling
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
Elasto-plastic contact stresses between working cylinder and support cylinder of
cold rolling using FEM are presented in this paper. Pressure and tractions resulted
from the rolling process were obtained by using a ...
On the Constitutive Equation of a Low Carbon Steel
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
The paper shows the results of the researches concerning the equation of
deformation behavior of low carbon steel. The behavior law is established starting
from the experimental torsion moment. The composed constitutive ...
Heavy Metal Ions Cu (II), Co (II) and Cr (III) bufunctionally Improved with Hydroxamic and Amidoxime Groups Chelating Ion Exchangers
(Universitatea "Dunărea de Jos'' din Galați, 2009)
Two new types of bifunctional chelating ion exchangers on the basis of
ethylacrylate acrylonitrile: divinylbenzene copolymers with hydroxamic acid and
amidoxime groups have been evaluated for Cu(II), Co(II) and Cr(III)ions ...
Improving of Functional Parameters for Pressure Casting Machine with High Degree of Finishing
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper presents a mathematic model of static and dynamic characteristics
for casting machine. This machine has a hydraulic action for the casting chamber
(her closing and introducing of molten alloy). This action is ...
Critical Analysis of "Maximum Stress Failure"
(Universitatea "Dunărea de Jos" din Galați, 2009)
The paper deals with critical considerations upon different points of view that
were enounced by some authors referring to Maximum Stress Failure Criterion for
composite materials. The considerations stem both from a ...
Study of the Sintering Process of Iron Powders Coated with Nano-Hydrocarbon and the Resulting Microstructure at Temperatures up to 1200°C
(Universitatea "Dunărea de Jos" din Galați, 2009)
The objective of the research is development and study of a new ecologically
friendly and technologically advanced method for introduction of carbon during
sintering of low alloyed iron powders ASC 100.29. The method is ...
