Effect of moisture content on some physical properties of barley
(Elsevier Science, 2013-05)
Physical properties of barley (Hordeum vulgare L.) seeds were determined as a function of moisture content. Several properties were studied in the moisture range from 13.15 to 45.82% dry basis, the length increased from ...
Magnetostratigraphy and magnetic parameters in Quaternary sequences of Balcarce, Argentina. a contribution to understand the magnetic behaviour in cenozoic sediments of South America
(Elsevier, 2017-06)
The South America Loess plateau covers a large part of Argentina. In this country, the Balcarce Hills represent at the moment a poorly studied area from a stratigraphic and paleoenvironmental point of view. This area is ...
The distance to the Galactic center determined by OB stars
(Springer, 2014-09)
The OB stars are concentrated near the Galactic plane and should permit a determination of the distance to the Galactic center. van Leeuwen’s new reduction of the Hipparcos catalog provides, after 824 Gould belt stars have ...
Toward an Understanding of Selective Alkyne Hydrogenation on Ceria: On the Impact of O Vacancies on H 2 Interaction with CeO 2 (111)
(American Chemical Society, 2017-11)
Ceria (CeO2) has recently been found to be a promising catalyst in the selective hydrogenation of alkynes to alkenes. This reaction occurs primarily on highly dispersed metal catalysts, but rarely on oxide surfaces. The ...

Gamma-Ray Variability from Wind Clumping in High-Mass X-Ray Binaries with Jets
(IOP Publishing, 2009-05)
In the subclass of high-mass X-ray binaries known as “microquasars”, relativistic hadrons in the jets launched by the compact object can interact with cold protons from the star’s radiatively driven wind, producing pions ...
