Effect of pretreatment temperature on the surface modification of diatomite with trimethylchlorosilane
(Journal of Porous Materials, 2016)
Diatomite samples from Costa Rica were purified
using acidic treatments with hydrochloric acid, thermally
treated (400–1000 C) and then silylated with
trimethylchlorosilane in toluene under inert atmosphere.
The ...
Atmospheric-Pressure Non-thermal Plasma-JET effects on PS and PE surfaces
(Institute of Physics Publishing, 2015-03)
The Atmospheric-Pressure Non-Thermal Plasma (APNTP) has become a topic of a great interest for a wide spectrum of applications in different industry branches, including the surface of treatment processes. In this work we ...
Automated plant species identification: Challenges and Opportunities
(IFIP Advances in Information and Communication Technology, 2016)
The number of species of macro organisms on the planet is
estimated at about 10 million. This staggering diversity and the need
to better understand it led inevitably to the development of classification
schemes called ...
Memoria de la exposición Puerto Limón: valorizando la arquitectura caribeña costarricense
(Instituto Tecnológico de Costa Rica, 2019)
La arquitectura caribeña costarricense si bien es
un tema abordado por distintas disciplinas debido a
su vinculación directa con el territorio y la identidad
cultural, no ha sido estudiada desde una
perspectiva de la ...
Comparative study of the optical behavior of a porphyrin encapsulated in sol-gel silica coatings and in solution as a function of pH
(Elsevier, 2016)
We report a comparative optical spectral study as a function of pH on a porphyrin encapsulated in a solgel
matrix and in methanol solution. Its response has been discussed in terms of pH-sensitivity as a
function of the ...
Analysis of source separation algorithms in industrial acoustic environments
(Institute of Electrical and Electronics Engineers Inc., 2015)
This paper shows the results from the computation cost evaluation of three blind source separation algorithms. The algorithms tested were: FastICA, Adaptive Algorithm Based on Natural Gradient, and Adaptive EASI Based on ...
Evaluación del saneamiento ambiental sostenible en las zonas atendidas por ASADAs en el Cantón Central
(Instituto Tecnológico de Costa Rica. Vicerrectoría de Investigación y Extensión (VIE). Escuela de Química. Centro de Investigación en Protección Ambiental (CIPA), 2016)
En varias regiones de Costa Rica, ya se registran condiciones de escasez de agua, las cuales irán en
aumento por el efecto del crecimiento poblacional, más aún, si se suma el efecto de la variación del
clima el ...

Diagnóstico, dinámica poblacional, caracterización bioquímica y molecular de nematodos noduladores (Meloidogyne spp.) en cultivos tropicales de Costa Rica
(Instituto Tecnológico de Costa Rica., 2012)
In this paper we conducted a morphological diagnosis and evaluated different primers to use
PCR-RFLPs as method of identification for Meloidogyne species related to tropical crops in the
Huetar Norte, Occidental Valley ...
Diagnóstico preliminar para la preparación de probetas y pruebas de laboratorio en la caracterización de dislocaciones y precipitaciones en la superaleación Nimonic 80A y Ti3Al con diferentes tratamientos térmicos y ensayados por fatiga de alta frecuencia
(Instituto Tecnológico de Costa Rica, 2015)
En este trabajo se analizaron probetas TEM (Microscopia Electrónica de Transmisión) de materiales usados en aplicaciones aeronáuticas. El principal objetivo de este proyecto es analizar los defectos intercristalinos presentes ...
