Thermal Parameters Analysis During Directional Solidification Of Al-Cu Eutectic Alloys
(Wiley, 2014-03)
Al-Cu eutectic alloy samples (Al-33.2wt.%Cu) were solidified directionally upward under conditions which produce the columnar-to-equiaxed transition (CET) phenomenon. The position of the CET was located in each sample and ...
A vanished memory: The Great War in present ArgentinaUne mémoire évanescente, la Grande Guerre dans l'Argentine d'aujourd'hui
(Université de Nanterre, 2014-12)
The First World War had a deep impact on Argentina, due to its historical, demographic, economic and cultural ties with Europe. A century later, except a couple of isolated signs, no traces of that experience remain in the ...

(2011-06-17)
This work presents the fabrication of multiwall carbon nanotubes (MWCNTs), its purification and the development of transparent electrical conductors (CETS) using these nanotubes, to achieve these objectives, the work ...
An appraisal of experimental designs: Application to enantioselective capillary electromigration techniques
(2021-01-01)
Enantioresolution processes are vital tools for investigating the enantioselectivities of chiral compounds. An analyst resolves to optimize enantioresolution conditions once they are determined. Generally, optimization is ...
An experimental investigation of the columnar-to-equiaxed grain transition in aluminumcopper hypoeutectic and eutectic alloys
(Elsevier Science, 2010-07-24)
Providing benchmark data of the thermal and metallographic parameters during the columnar-to-equiaxed transition (CET) in a wide range of alloy concentrations is of fundamental importance for understanding this phenomenon ...
Identifications, Cultures, and "Groupness": Reflecting on Culture from Ethnographic Research in Argentina
(University of Ottawa, 2015-12)
This paper reflects on the precautions to be taken into account when addressing the study, from the point of view of the social sciences, of cultures and communities. This is done through ethnographic research in a ...
