Study of Seasonal Rainfall Infiltration Via Time-Lapse Surface Electrical Resistivity Tomography: Case Study of Gamboa Area, Panama Canal Watershed
(2013-12-18)
The present investigation was focused on the variations in rainwater infiltration experienced by soils of Gamboa zone (Panama Canal Watershed) during various seasons of the year, employing a time-lapse analysis of electrical ...
Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
(06/01/2001)
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
Modeling Abiotic Processes of Aniline in Water-Saturated Soils
(03/18/2000)
The long-term interactions of aromatic amines with soils are important in defining the fate and transport of these compounds in the environment. Abiotic loss of aniline from the aqueous phase to the soil phase occurs with ...
Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils
(08/04/2001)
Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
Heterogeneous photochemical reactions of decabromodiphenyl ether
(11/03/2009)
Brominated diphenyl ethers area major class of brominated flame retardants, with production of decabromodiphenyl ether (DBDPE) contributing significantly to this total. Although little is known about the mechanisms and ...
Scintillometer networks for calibration and validation of energy balance and soil moisture remote sensing algorithms
(05/07/2007)
Accurate estimation of sensible and latent heat fluxes as well as soil moisture from remotely sensed satellite images poses a great challenge. Yet, it is critical to face this challenge since the estimation of spatial and ...

Detección de índice de área foliar por firma espectral de cultivo de arroz (Oryza sativa L.)
(2018-07-19)
El objetivo del estudio fue determinar las longitudes para la detección espectral del índice de área foliar en cultivo de arroz variedad IDIAP 52-05. Se realizaron mediciones de campo con un espectrorradiómetro y medidas ...
Composition, Diversity, and Tree Structure of a Tropical Moist Forest in Gamboa, Colon, Panama
(2016-03-22)
This study focuses on the floristic diversity of the forest trees found at Cerro Pelado Tropical Hydrology Observatory in Gamboa, Colon, Panama. Field work for the quantitative inventory was carried out in November 2012. ...
