Dispersion estimates for Spherical Schrödinger Equations
(Birkhauser Verlag Ag, 2016-11)
We derive a dispersion estimate for one-dimensional perturbed radial Schrödinger operators. We also derive several new estimates for solutions of the underlying differential equation and investigate the behavior of the ...
Contrasting patterns of natal dispersal of a south temperate House Wren population at local and regional scales
(Springer, 2021-07)
Dispersal constitutes one of the main processes that shape population genetic structure and dynamics. Combining a capture-mark-resighting methodology and molecular genetics analyses, we studied the natal dispersal behaviour ...
Influencia del método de dispersión en el fraccionamiento físico de un suelo de Argentina centralFour dispersion methods, typically applied to soil physical fractionation protocols, were compared in a Mollisol from mountain grasslands from central Argentina. The proportion of coarse and fine soil fractions obtained after dispersion was significantly different. Considering that mineral fractions after dispersion using glass beads did not differ from granulometric analysis, this method achieved better results than sonication or shaking with chemical dispersant for evaluated soils.
(Asociación Argentina de la Ciencia del Suelo, 2020-07)
Se compararon cuatro métodos de dispersión de suelos, ampliamente utilizados en protocolos de fraccionamiento físico, sobre un Molisol de pastizales montañosos del centro de Argentina. La proporción de las fracciones fina ...
Natal dispersal and philopatry of chimango caracaras (Milvago chimango) in suburban, rural and natural habitats, determined by band recovery and re-sighting data
(Csiro Publishing, 2017-03)
Natal dispersal is a process whereby birds move from their birthplace to the site of their first attempt at reproduction. This process has strong implications for the dynamics and genetic structure of populations. However, ...
Patrones de dispersión y banco de semillas de Cedrela fissilis Vell., en la selva misionera (selva paranaense)Dispersal patterns and seed bank of Cedrela fissilis Vell., in the subtropical forest of Misiones
(Universidad Nacional de Misiones. Facultad de Ciencias Forestales. Instituto Subtropical de Investigaciones Forestales, 2010-11-29)
La Selva Misionera (Selva Paranaense) tiene entre sus especies nativas, aquellas denominadas del grupo de las "maderas de ley", una de las más importantes es el cedro misionero (Cedrela fissilis). Considerada especie de ...
Signal convergence in fruits: a result of selection by frugivores?
(Wiley Blackwell Publishing, Inc, 2010-01)
The Dispersal Syndrome hypothesis remains contentious, stating that apparently nonrandom associations of fruit characteristics result from selection by seed dispersers. We examine a key assumption under this hypothesis, ...
Evaluation of the hydrodynamic behaviour of turbulence promoters in parallel plate electrochemical reactors by means of the dispersion model
(Pergamon-Elsevier Science Ltd, 2011-08)
The hydrodynamic behaviour of electrochemical reactors with parallel plate electrodes is experimentally studied using the stimulus-response method either with an empty reactor or with different turbulence promoters. ...
Perfomance evaluation of maximum likelihood sequence estimation receivers in lightwave systems with optical amplifiers
(Planta Piloto de Ingeniería Química, 2005-12)
Maximum likelihood sequence estimation (MLSE) has been proposed in earlier literature to combat the e®ects of nonlinear dispersion in intensity modulation/direct detection (IM/DD) optical channels. In this paper, we develop ...
Energy dispersive inelastic X-ray scattering (EDIXS) spectroscopy: A review
(Pergamon-Elsevier Science Ltd, 2019-04)
This work presents an overview of a novel spectroscopic tool: Energy Dispersive Inelastic X-ray Scattering (EDIXS) spectroscopy. By the application of EDIXS, the local chemical environment of an element of interest can be ...
Diplochory in two Jatropha (Euphorbiaceae) species of the Monte Desert of Argentina
(Wiley Blackwell Publishing, Inc, 2010-04)
The potential explosive seed dispersal under controlled conditions and the dispersal by ants in natural populations are compared between two diplochoric species: Jatropha hieronymi Kuntze and J. excisa Griseb. The seeds ...
