Orbitals in general chemistry, Part II: Mathematical Realities
(2021)
In Part II of a three-part series, we discuss two factors absent from textbooks of general chemistry that are important in a discussion
of teaching orbitals. First, atomic orbitals are shown systematically to comprise ...
Proyecciones climáticas para la Isla del Coco de un conjunto de modelos CMIP5
(2018-02-14)
Se seleccionaron 14 corridas de modelos climáticos globales de circulación general que
generan proyecciones climáticas mensuales de precipitación y temperatura del grupo llamado
(CMIP5), AR5, IPCC. La selección de los ...
Optimization of a Fungally Bioaugmented Biomixture for Carbofuran Removal in On-Farm Biopurification Systems
(2016)
Biomixtures comprise the active part of biopurification systems (BPS) for the removal of pesticide-containing wastewater from agricultural origin. Considering that biomixtures contain an important amount of lignocellulosic ...
Evaluation of Extreme Waves Associated with Cyclonic Activity on San Andrés Island in the Caribbean Sea since 1900
(2015)
San Andrés Island is one of the most important tourist destinations in the Caribbean Sea. The extreme waves associated with storms and hurricanes since 1900 were studied. A total of 17 important events was identified in ...
Differences in plasmatic butyrylcholinesterases (BChE) values between Pacific and Caribbean populations of terciopelo (Bothrops asper) in Costa Rica
(2019)
The terciopelo (Bothrops asper) inhabits human-modified environments such as agricultural areas, becoming more prone to be exposed to organophosphate insecticides. These chemicals can inhibit plasmatic butyrylcholinesterases ...
Sismicidad localizada por la Red Sismológica Nacional durante el 2022
(2023-02-10)
Durante el año 2022, la Red Sismológica Nacional (RSN) localizó 4763 sismos locales, lo cual equivale a la energía
sísmica liberada por un terremoto de magnitud momento (Mw) 7,0. Los epicentros se concentraron principalmente ...
Novelties in Costa Rican Stelis (Orchidaceae: Pleurothallidinae): two new species and a new record in the "Dracontia group"
(2017)
Stelis dies-natalis and Stelis aenigma, belonging to a group of mostly Middle American species alternatively placed in genus Dracontia, are described and illustrated based on living material. They were both ...
Fourier analysis on the affine group, quantization and noncompact Connes geometries
(2008-04)
We find the Stratonovich-Weyl quantizer for the nonunimodular affine group of the line. A noncommutative product of functions on the half-plane, underlying a noncompact spectral triple in the sense of Connes, is obtained ...
Responses of aquatic macroinvertebrates to human pressure in a tropical highland volcanic basin: Birrís River, Irazú Volcano (Costa Rica)
Respuestas macroinvertebrados acuáticos a la presión humana en una cuenca tropical volcánica alta: Río Birrís, Volcán Irazú (Costa Rica)
(2018)
Background. Tropical mountain rivers are strategic sources of water for human development while biological communities are indicators of the status of these ecosystems. However, volcanic basins close to large urban areas ...
Photosynthetic characterization of two Nannochloropsis species and its relevance to outdoor cultivation
(2020)
Despite the increased interest in exploring the potential of algal biomass production for food stock and renewable energy, very
little work has been done in developing reliable screening protocols to enable the identification ...
