Emphasizing the Toxicity of Heavy Metal ions on Plants: Monitoring with an Amino Acids Assay
(Universitatea "Dunărea de Jos" din Galați, 2014)
In order to emphasize modifications on living organisms resulted from
interaction with heavy metals, we applied a simple, sensitive, quick, inexpensive
and reproducible method. It evaluates modifications through determining ...
Experimental Research on Heating Behavior of Some Steels During Hot Metallurgical 1453 – 083X
(Universitatea "Dunărea de Jos" din Galați, 2014)
The heating of steel semi-products in view of hot rolling process or heat
treatments is achieved at the large scale in propulsion ovens for the increase of
their deformability and to improving mechanical characteristics ...
Behavior of Cold Rolling Emulsions in the Obtaining Process of Steel Strips
(Universitatea "Dunărea de Jos" din Galați, 2014)
The research was focused on determining an optimum rolling emulsion to be
used on a cold rolling mill from Galfinband Galati Romania. In this plant are
obtained steel strips with the thickness of 0.7-0.8 mm. The main ...
Effects Exerted by Slag Carried over from Converter in the Ladle on the Aluminum Assimilation
(Universitatea "Dunărea de Jos" din Galați, 2014)
In the present paper are shown aspects of the influence exerted by the some
less controlled parameters of BOF steelmaking, mainly of slag characteristics at
tapping. Following the necessities to control the steel ...
Siderurgy Slags Recovery in Building Industry
(Universitatea "Dunărea de Jos" din Galați, 2014)
During the metallurgical processes of iron and steel elaboration, besides the
basic products, it results a serious of secondary products (wastes) in high quantities
but with a high recycle – recovery potential, and their ...
Resesrches on the Production of Copper-Based Composites by Powder Metallurgy Methods
(Universitatea "Dunărea de Jos" din Galați, 2014)
The article presents how to obtain copper matrix composite with alloy
particles of NiCrBFeAl as complementary phase. The samples were obtained by
powder metallurgy methods using different percentages of the additional ...
Recycling of Cellulosic Waste in the Energy Sector
(Universitatea "Dunărea de Jos" Galați, 2014)
Biomass is one of the Earth’s most abundant and precious resources. It offers
not only food but also energy, materials used for construction, chemicals and much
more. Biomass has always been used for generating energy ...
Structuras of the Eutectoid Zn-Al Alloy Obtained by Directed Solidification
(Universitatea "Dunărea de Jos" din Galați, 2014)
This work analyses the structure of the eutectoid Zn-Al based alloy
directionally solidified, with cooling rates ranging between 8.5-0.4 oC/sec. During
cooling, the temperature gradient in the liquidus zone, respectively ...

(Universitatea "Dunărea de Jos" din Galați, 2014)
Getting reusable aluminosilicate materials, based on the geopolymerization
reaction mechanism of some physical and mechanical material particular, has been
imposed in the recent years in building materials.
This paper ...
Silica thin Films Obtaining by Sol-Gel Dip Coating with Controlled Optical Properties
(Universitatea "Dunărea de Jos" din Galați, 2014)
Transparent oxide films are widely employed as antireflection or high
reflection coatings, band-pass filters and narrow-band-filters in various optical and
electronic devices. The performances of these devices are based ...
