Towards autotrophic tissue engineering: photosynthetic gene therapy for regeneration
(Biomaterials, 2016)The use of artificial tissues in regenerative medicine is limited due to hypoxia. As a strategy to overcome this drawback, we have shown that photosynthetic biomaterials can produce and provide oxygen independently of blood ... -
The release of wastewater contaminants in the Arctic: A case study from Cambridge Bay, Nunavut, Canada
(Scopus, 2016)The treatment of municipal wastewater in the Arctic is challenging due to a variety of financial, operational, climatic and technical issues. To better understand the efficacy of current wastewater treatment in this ... -
Synthesis, properties, and two-dimensional adsorption characteristics of 5-amino[6]hexahelicene
(Willy, 2016)A convergent synthesis of racemic 5-amino[6]hexahelicene is described. Cross-coupling reactions are used to assemble a pentacyclic framework, and a metal-catalyzed ring-closure comprises the final step. The enantiomers ... -
Surface chemical and color characterization of juvenile tectona grandis wood subjected to steam-drying treatments
(2016)The color of Tectona grandis wood is an attribute that favors its commercialization, however, wood color from fast-growth plantation trees is clear and lacks uniformity. The aim of this work is to characterize steamed ... -
Scientometric analysis of Colombian research on bio-inoculants for agricultural production
(Universitas Scientiarum, 2016)The excessive use of synthetic chemical inputs in agricultural production has led to the disruption of biogeochemical cycles. One of the alternatives that arose within the systems of sustainable agriculture was the partial ... -
Production and quality analysis of pellets manufactured from five potential energy crops in the Northern Region of Costa Rica
(Biomass and Bioenergy, 2016)Modifications to a pellet manufacturing process must be made based on the characteristics of raw material used. The purpose of this work was to determine the alternations required to a wood pellet manufacturing process ... -
Population status of the tree Sacoglottis holdridgei (Humiriaceae) at Isla del Coco National Park, Costa Rica
(Revista de Biología Tropical, 2016)Isla del Coco is the only oceanic island in the Eastern Pacific with humid tropical climate. Its forests have a particular structure with a unique array of plant species and high endemism. There are few studies on the ... -
Antierótica feroz y otras cuestiones paradójicas
(Revista Mexicana de Sociología, 2016)In 2013, Antierótica feroz, a short story collection by Laura Fuentes, was published in Costa Rica. This text came at a time of aesthetic and ideological rupture in the region, since it reflects parody and, at the same ... -
PEDOT:PSS: A conductive and flexible polymer for sensor integration in Organ-on-Chip platforms
(Procedia Engineering, 2016)Sensing and stimulating microstructures are necessary to develop more specialized and highly accurate Organ-on-Chip (OOC) platforms. In this paper, we present the integration of a conductive polymer, poly (3,4-ethylened ... -
IBA efficiency on mini-cutting rooting from teak (Tectona grandis Linn F.) clones
(Revista Arvore, 2016)This study aimed to evaluate IBA efficiency in mini-cuttings rooting based on four Tectona grandis clones. Vegetative samples were collected in a hydroponic mini-clonal hedge in Verde Novo reforestation company at Colider, ... -
Generalized brillinger-like transforms
(IEEE Signal Processing Letters, 2016)We propose novel transforms of stochastic vectors, called the generalized Brillinger transforms (GBT1 and GBT2), which are generalizations of the Brillinger transform (BT). The GBT1 extends the BT to the cases when the ... -
Optical performance of finished and unfinished tropical timbers exposed to ultraviolet light in the field in Costa Rica
(Wood Material Science & Engineering, 2016)This study evaluated wood color change (ΔE*) and the surface quality in 10 tropical wood species painted with three finishes (composed of wax and polyurethane). Two weathering conditions were tested: natural weathering ... -

Molecular identification of Trichoderma spp. in garlic and onion fields and In Vitro antagonism trials on Sclerotium cepivorum
(Revista Brasileira de Ciencia do Solo, 2016)Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby ... -
Model reduction of a flexible-joint robot: a port-Hamiltonian approach
(IFAC-PapersOnLine, 2016)In this paper we explore the methodology of model order reduction based on singular perturbations for a flexible-joint robot within the port-Hamiltonian framework. We show that a flexible-joint robot has a port-Hamiltonian ... -
Kiln drying behavior utilizing drying rate of lumber from six fast-growth plantation species in Costa Rica
