New Silver Nanosensor for Nickel Traces: Synthesis, Characterization and Analytical Parameters
(David Publishing Company, 2011-12-30)
A new fluorescence silver nanosensor assisted by surfactant has been synthesized and applied to ultra trace nickel determination. Operational variables which influence nanomaterial synthesis have been studied and optimized. ...
P300: Waves Identification with and without Subtraction of Traces
(Georg Thieme Verlag Kg, 2017-10-01)
Introduction The P300 test requires well-defined and unique criteria, in addition to training for the examiners, for a uniform analysis of studies and to avoid variations and errors in the interpretation of measurement ...
On nilpotency of generalized almost-jordan right-nilalgebras
(World Scientific Publishing Co. Pte Ltd, 2008)
We study the variety of algebras A over a field of characteristic ≠ 2, 3, 5 satisfying the identities xy=yx and β ((xx)y)x-((yx)x)x + γ ((xx)x)y-((yx)x)x=0, where β, γ are scalars. We do not assume power-associativity. We ...

Lower Cretaceous anoxic conditions IN the Austral basin, south-western Gondwana, Patagonia Argentina
(Pergamon-Elsevier Science Ltd., 2014-02)
The reconstruction of palaeo-oxygenation levels in marine deposits from the Cretaceous has obtained a huge interest all around the world in recent years. This fascinating topic is here pointed out for the first time in the ...
Rossby wave propagation tracks in southern hemisphere mean basic flows associated to generalized frosts over southern South America
(CENTRO CIENCIAS ATMOSFERA UNAM, 2010)
Based on previous observational studies on cold extreme events over southern South America, some recent studies suggest a possible relationship between Rossby wave propagation remotely triggered and the occurrence of frost. ...
New Analytical Methodology for Sb(III) Traces Quantification as Emergent Contaminant in Drinks Packaged PET Samples by Solid Surface Fluorescence
(Scientific Research Publishing, 2019-09)
Emerging contaminants constitute a set of substances that are released into the environment for which regulations are currently not established for their environmental monitoring, being antimony one of them. A new methodology ...
Gyrophyllites cristinae isp. nov. from lower ordovician shallow-marine deposits of northwest Argentina
(Taylor & Francis, 2019-10)
The lower Paleozoic marine siliciclastic succession of the Central Andean Basin, northwestern Argentina, provides a valuable record of the onset of the Great Ordovician Biodiversification Event in western Gondwana. A new ...
Comparative study of equatorial and high-latitude over-the-horizon radar parameters using ray-tracing simulations
(Institute of Electrical and Electronics Engineers, 2020-01)
Certain parameters of over-the-horizon radars (OTHRs) need regular adjustment to keep constant illumination of a target due to ionospheric variability. Feasible values of these parameters for an OTHR operation, namely, the ...
