Silica in plant tissues has been suggested as a component for enhancing mechanical properties, and as a physical barrier. Pineapples present in their shell and bracts rosette-like microparticles that could be associated ...

The extended National Waters Inventory of Scotland (NWIS) monitoring network in combination with an extensive, supplementary low flow sampling campaign was used to create isoscapes of surface water for management purposes ...

Production of bio-based acetate is commonly hindered by the high costs of the downstream processing. In this paper, a model is developed to describe a new method that recovers acetate salts using anion exchange resins, and ...

Determina la concentración de los hidrocarburos biogénicos en aire en el Bosque Nuboso de la Reserva Biológica Monteverde, Costa Rica. Se implemento la metodología analítica para la determinación de las concentraciones de ...

Los hidrogeles poliméricos presentan características estructurales de enorme interés por su aplicación en el campo de la biomedicina y la agricultura. Los objetivos del presente estudio fueron preparar hidrogeles por ...

The location of Costa Rica on the Central American Isthmus creates unique microclimate systems that receive moisture inputs directly from the Caribbean Sea and the Pacific Ocean. In Costa Rica, stable isotope monitoring ...

Contribuye a la calidad del aire de la ciudad de San José y al mejoramiento de la salud pública mediante la determinación de la concentración de éter metil terc-butílico en el aire de la ciudad de San José. Se realizaron ...

A great interest has arisen in establishing the impact of organic compounds on human health and air quality, especially those compounds emitted by automotive traffic. Knowledge of urban air pollutant concentrations is ...

This work describes the production of secondary lead in a smelter located in Costa Rica. The only input of the plant is scrap automotive batteries. We describe the environmental management strategies used for waste ...

This study presents a stable isotope hydrology and geochemical analysis in the inland Pacific Northwest (PNW) of the USA. Isotope ratios were used to estimate mean transit times (MTTs) in natural and human-altered watersheds ...
