A Comparison of Two Methodological Approaches for Determining Castor Bean Suitability in Chile
(MDPI, 2020)
Castor bean (Ricinus communisL.) contains ricinoleic acid, making it one of the world's most important oil-seeds. There are few studies on this species in Chile, despite its potential as an industrial crop. This study ...
Induced OWA operators in linear regression
(IOS Press, 2020)
The induced ordered weighted average (IOWA) is an aggregation operator that provides a parameterized family of operators between the minimum and the maximum. This work presents a new application that uses the simple linear ...
Solvability of a nonlinear Neumann problem for systems arising from a burglary model
(Elsevier, 2014)
We study a one dimensional version of a problem that arises in mathematical modeling
for burglary of houses. Our approach uses techniques inspired by coincidence degree, see
Mawhin (1979). A priori estimates are obtained ...
B modes and the sound speed of primordial fluctuations
(Amer Physical Soc, 2015)
It was recently shown that a large value of the tensor to scalar ratio r implies a constraint on the minimum value of the sound speed c(s) of primordial curvature perturbations during inflation that is stronger than current ...
Another upper bound for the domination number of a graph
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1986)
If δ and ∆ are the minimum and máximum degrees of a simple graph G of size n, then, for its domination number B(G), we show that B(G) ≤ [(n-∆-1) (n- δ-2)/(n-1)]+2.
Reconstructing past variations in environmental conditions and paleoproductivity over the last similar to 8000 years off north-central Chile (30 degrees S)
(Copernicus Gesellschaft MBH, 2020)
The aim of this project was to establish past variations in the main oceanographic and climatic features of a transitional semiarid ecosystem on the north-central Chilean coast. We analyzed recent sedimentary records ...
Application of seismic refraction tomography for tunnel design in santa clara mountain, san juan, argentina
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2011)
A geophysical survey involving seismic refraction tomography (SRT) for mapping 'P' waves was carried out in Sierra Santa Clara, San Juan Province, Argentina in July 2009. The purpose of the geophysical survey was to determine ...
Latissimus dorsi transposition for sequelae of obstetric palsy.
(2011-11-16)
Background: In obstetric palsy, limitation in the external abduction and rotation of the shoulder is the most frequent
sequelae. Glenohumeral deformity is the result of muscular imbalance between the external and internal ...
Fault-related folding, drainage network evolution and valley incision during the Neogene in the Andean Precordillera of Northern Chile
(ELSEVIER, 2005-02-15)
We describe Neogene drainage network development before, during and after regional folding in the Precordillera of the Andes of Northern Chile (18degrees-19degreesS). The drainage network developed on an extensive regular ...
Gap-phase dynamics and coexistence of a long-lived pioneer and shade-tolerant tree species in the canopy of an old-growth coastal temperate rain forest of Chiloe Island, Chile
(BLACKWELL PUBLISHING, 2008-09)
Aim A major question with regard to the ecology of temperate rain forests in south-central Chile is how pioneer and shade-tolerant tree species coexist in old-growth forests. We explored the correspondence between tree ...
