Quantifying sources and transport pathways of Surface sediments in the Gulf of San Jorge, Central Patagonia (Argentina)
(Oceanography Society, 2018-09)
The Gulf of San Jorge (GSJ) is a semicircular basin, approximately 160 km long and 250 km wide, located in the central part of Patagonia between 45°S and 47°S, lacking any present-day major perennial tributaries. The grain ...
Distinct changes in evoked and resting globus pallidus activity in early and late Parkinson's disease experimental models
(Wiley Blackwell Publishing, Inc, 2007-12)
The main clinical manifestations of Parkinson´s disease are caused by alterations of basal ganglia activity that are tied in with the progressive loss of mesencephalic dopaminergic neurons. Recent theoretical and modeling ...
Coherent electron emission from O2 in collisions with fast electrons
(Springer, 2017-08)
Abstract: Absolute double differential cross sections (DDCS) of secondary electrons emitted in ionization of O2 by fast electrons have been measured for different emission angles. Theoretical calculations of atomic DDCS ...
Power of Stable isotope techniques to detect size-based feeding in marine fishes
(Inter-Research, 2010-05)
Stable isotope techniques are now the most frequently applied method to investigate size-based variation in fish trophic position (TP), and data suggest changes in TP with body size are common. However, of 131 collated ...
Ab Initio Study of the Electronic Structure, Elastic Properties, Magnetic Feature and Thermodynamic Properties of the Ba2NiMoO6 Material
(Springer/Plenum Publishers, 2018-05)
We report first-principles calculations of the elastic properties, electronic structure and magnetic behavior performed over the Ba2NiMoO6 double perovskite. Calculations are carried out through the full-potential linear ...
On the influence of statistics on the determination of the mean value of the depth of shower maximum for ultra high energy cosmic ray showers
(IOP Publishing, 2012-07)
The chemical composition of ultra high energy cosmic rays is still uncertain. The latest results obtained by the Pierre Auger Observatory and the HiRes collaboration, concerning the measurement of the mean value and the ...
Modified vacuum tubes for overheating limitation of solar collectors: A dynamical modeling approach
(Pergamon-Elsevier Science Ltd, 2018-09)
In this paper are presented two designs of vacuum tubes designed to avoid the overheating of solar collectors. As we discuss, this behavior must be studied by considering the collector's nonlinear dynamic, which is numerically ...
7-oxo-DHEA enhances impaired M. tuberculosis-specific T cell responses during HIV-TB coinfection
(BioMed Central, 2020-01)
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), affecting approximately one third of the world’s population. Development of an adequate immune response will determine disease progression or ...
Identification of neuronal enhancers of the proopiomelanocortin gene by transgenic mouse analysis and phylogenetic footprinting
(American Society for Microbiology, 2005-04)
The proopiomelanocortin (POMC) gene is expressed in the pituitary and arcuate neurons of the hypothalamus. POMC arcuate neurons play a central role in the control of energy homeostasis, and rare loss-of-function mutations ...
Limits on active-sterile neutrino mixing parameters using heavy nuclei abundances
(World Scientific, 2021-04)
The production of heavy-mass elements due to the rapid neutron-capture mechanism (r-process) is associated with astrophysical scenarios, such as supernovae and neutron-star mergers. In the r-process the capture of neutrons ...
