Mitochondrial DNA analysis suggests a chibchan migration into Colombia
(Pontificia Universidad Javeriana, 2015)
The characterization of mitochondrial DNA (mtDNA) allows the establishment of genetic structures and phylogenetic relationships in human populations, tracing lineages far back in time. We analysed samples of mtDNA from ...
The emergence of cognitive short-term planning: Performance of preschoolers in a problem-solving task
(Universidad Catolica de Colombia, 2015)
The aim of this study is to identify patterns of the cognitive planning process of young children emerging in the context of a problem solving task. Using a complex dynamic systems approach, this paper depicts the main ...
Volatile organic compounds in the atmosphere of Mexico City
(Elsevier Ltd, 2015)
The Mexico City Metropolitan Area (MCMA) is one of the most polluted megacities in North America. Therefore, it is an excellent benchmark city to understand atmospheric chemistry and to implement pilot countermeasures. Air ...
Tuboerculosis in Barranquilla, 1930-1960
(Universidad del Norte, 2015)
This article analyzes the role of tuberculosis in the city of Barranquilla between 1930 and 1960. It demonstrates how it became into an endemic disease due to the increment of morbidity and mortality that attract the ...
Estimate of induced stress during filling and discharge of metallic silos for cement storage
(Universidad Nacional de Colombia, 2015)
The present article show the structural analysis realized to metallic silo for storage cement through of the parametric model development in the finite element software ASNYS APDL, the fill and discharge pressures applied ...
Towards better BBB passage prediction using an extensive and curated data set
(Wiley-VCH Verlag, 2015)
In the present report, the challenging task of drug delivery across the blood-brain barrier (BBB) is addressed via a computational approach. The BBB passage was modeled using classification and regression schemes on a novel ...
Millimeter-wave bandpass filter on LCP using CSRR-loaded triangular-shape quarter-mode substrate integrated waveguide
(John Wiley and Sons Inc., 2015)
A millimeter-wave two-pole bandpass filter (BPF) with an asymmetrical frequency response is realized on a flexible liquid crystal polymer substrate for wearable/conformal wireless applications. The design uses the ...
Transient dynamic analysis of shear deformable shallow shells using the boundary element method
(Elsevier Ltd, 2015)
The complexity involved in the dynamic response of plates brings many challenges from a mathematical standpoint. In this work, the transient dynamic analysis of elastic shallow shells under uniformly distributed pressure ...
Elastodynamic analysis of thick multilayer composite plates by the Boundary Element Method
(Tech Science Press, 2015)
Dynamic stress analysis of laminated composites plates represents a relevant task in designing of aerospace, shipbuilding and automotive components where impulsive loads can lead to sudden structural failure. The mechanical ...
QuBiLs-MAS method in early drug discovery and rational drug identification of antifungal agents
(Taylor and Francis Ltd., 2015)
The QuBiLs-MAS approach is used for the in silico modelling of the antifungal activity of organic molecules. To this effect, non-stochastic (NS) and simple-stochastic (SS) atom-based quadratic indices are used to codify ...
