Variation in plasma cholinesterase activity in the clay-colored robin (Turdus grayi) in relation to time of day, season, and diazinon exposure
Cholinesterase (ChE) activity in birds is subject to interspecific and intraspecific species variations. Factors that influence enzyme activity have to be taken into account in order to obtain anExpand

Cathodoluminescence Study of InP Photonic Structures Fabricated by Dry Etching
Ridge waveguides fabricated by inductively coupled plasma (ICP) etching using chlorine-based gases were studied by spectrum image cathodoluminescence (CL). Structures with different dimensionsExpand

Raman spectrum of Si nanowires: temperature and phonon confinement effects
The Raman spectrum of Si nanowires (NWs) is a matter of controversy. Usually, the one-phonon band appears broadened and shifted. This behaviour is interpreted in terms of phonon confinement; however,Expand

Hsp90 interaction with Cdc2 and Plo1 kinases contributes to actomyosin ring condensation in fission yeast
In Schizosaccharomyces pombe, cytokinesis occurs by ordered recruitment of actomyosin components at the division site, followed by lateral condensation to produce a ring-like structure early inExpand

Mechanical Stress in InP Structures Etched in an Inductively Coupled Plasma Reactor with Ar/Cl2/CH4 Plasma Chemistry
We investigated the crystal lattice deformation that can occur during the etching of structures in bulk InP using SiNx hard masks with Ar/Cl2/CH4 chemistries in an inductively coupled plasma reactor.Expand

Optical and morphological characteristics of LP MOVPE grown lattice matched GaInP/GaAs heterostructures
InGaP alloy is a very promising material for several applications (BHT transistors, LEDs, etc). Nevertheless, it presents several problems related to the large lattice mismatch between the binaryExpand

Cathodoluminescence Characterization of Dilute Nitride GaNSbAs Alloys
The effects of ex situ annealing in N ambient and in situ annealing in As ambient on GaNSbAs/GaAs structures grown by molecular beam epitaxy were investigated by low temperature cross-sectionalExpand

Fourier Transform Study of the Complex Electric Field Induced on Axially Heterostructured NWs.
We present in this work a study of the effect of Raman enhancement on axially heterostructured semiconductor nanowires (NWs). The investigation is motivated by the recent detection of a Raman signalExpand

The properties of GaInP/GaAs heterostructures as a function of growth temperature
In order to find the best conditions under which ordering process is reduced InGaP layers were grown on GaAs substrates by Metal Organic Vapor Phase Epitaxy (MOVPE) at low pressure in the temperatureExpand
Placas de concreto de ultra alto desempeño (UHPC) como solución para pisos en estaciones de Transmilenio
The following work is contained in the research Project of Ultra High Performance Concrete (UHPC) for special built applications in Colombia. Developed by Argos, Colciencias and the PontificiaExpand
