Weighted Lp estimates on the infinite rooted k-ary tree
(Springer, 2021-10-25)
In this paper sufficient conditions for weighted weak and strong type (p, p) estimates with p>1 for the centered maximal function on the infinite rooted k-ary tree are provided. Here the line initated by the authors and ...
Effects of stone pine (Pinus pinea L.) plantation spacing on initial growth and conelet entry into production
(Springer, 2019-05)
Stone pine (Pinus pinea L.) is well-known for its fruits, the pine nuts, which are considered a delicacy and are the most expensive dry fruits in the world. This fruit is harvested mostly from natural forests, and limited ...
Optimal Production Strategies for the Development of Mature Oil Fields through Polymer Flooding
(American Chemical Society, 2021-07)
Polymer flooding is one of the most extensively applied techniques for enhanced oil recovery (EOR) that relies on increasing the injected fluid viscosity by adding polymers in different concentrations. The aim is to improve ...
Phytolith analysis of Cyperaceae from the Pampean region, Argentina
(Csiro Publishing, 2009-11)
Cyperaceae, along with Poaceae, is the main silica accumulator. Although the anatomical-taxonomic and palaeobotanical relevance of phytoliths has been well established, there are no studies that deal with the qualitative ...
On period doubling bifurcations of cycles and the harmonic balance method
(Pergamon-Elsevier Science Ltd, 2006-02)
This works attempts to give quasi-analytical expressions for subharmonic solutions appearing in the vicinity of a Hopf bifurcation. Starting with well-known tools as the graphical Hopf method for recovering the periodic ...
Los instrumentos para hacer fuego del sitio Huachichocana (Depto. de Purmamarca, Pcia. de Jujuy, República Argentina)
(Centro Argentino de Etnología Americana, 1985)
Se analizan doce instrumentos activos y diecisiete pasivos para hacer fuego del sitio Huachichocana (Purmamarca, Pcia. de Jujuy, Argentina). Se describe la técnica de producción del fuego por el sistema de fricción rotativa ...
Analysis of the hydrogen electrode reaction mechanism in thin-layer cells. 1. Theory
(Elsevier Science Sa, 2010-12)
This work develops the equations that relate the kinetic parameters of the hydrogen electrode reaction (HER) with the current density (j) vs. potential (E) dependences of a thin-layer cell (TLC). Two operation modes of the ...
Observación versus modelos en el Tercer Cuadrante Galáctico
(Asociación Argentina de Astronomía, 2013-11)
Presentamos una síntesis de los resultados de un extenso estudio fotométrico UBVI realizado sobre un grupo de 14 campos ubicados en el tercer cuadrante de nuestra galaxia, orientado a establecer las propiedades de su ...
In vitro plant regeneration and cryopreservation of Arachis glabrata (Fabaceae) using leaflet explants
(Springer, 2017-12)
Arachis glabrata Benth (perennial peanut) is a rhizomatous legume with high forage value and great potential for soil conservation as well as it displays valuable plant genetic resources for the cultivated edible peanut ...
Precise electroosmotic flow measurements on paper substrates
(Wiley VCH Verlag, 2021-04)
A novel method for electroosmotic flow (EOF) measurement on paper substrates is presented; it is based on dynamic mass measurements by simply using an analytical balance. This technique provides a more reliable alternative ...
