Induced Desorption of DDT, DDD, and DDE from a Contaminated Sediment
(1997-03-01)
Release profiles of p,p′-DDT, p,p′-DDD, and p,p′-DDE from sediment collected from Indian Creek, Alabama, were measured with a gas purge-induced desorption technique and compared to a model developed in this work. DDT entered ...
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 ...
Estimates of Biomass and Fixed Carbon at a Rainforest in Panama
(2012-10-03)
This paper presents an estimation of the quantity of carbon fixed in trees in a one hectare (ha) plot at the Cerro Pelado-Gamboa
Hydrology Tropical Observatory, which is located in the province of Colon, Panama. The ...
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 ...
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 ...
Increase In Simple Precipitation Intensity Index In Panama
(2011-09-30)
The paper describes trends in climate change indices in the Republic of Panama by using long-term
meteorological data sets from the Panama Canal and MRI-AGCM. Simple precipitation intensity index
from eleven climate change ...
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 ...
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. ...
Modeling Short-Term Soil−Water Distribution of Aromatic Amines
(1998-12-08)
The applicability of a distributed parameter model for describing the distribution of aniline and α-naphthylamine between soil and aqueous phases at short contact times was assessed. Mass action equations considered in the ...
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 ...
