Recruiting a PRA Team That Works
(1997-01)In 1949 the world bank sent 14 international advisers to Colombia. These expert in foreign exchange, transportation, industry, agriculture, and others represented the first mission of its kind to attack "underdevelopment" ... -
Household stored water quality in an intermittent water supply network in Panama
(Journal of Water, Sanitation and Hygiene for Development washdev2020156Journal of Water, Sanitation and Hygiene for Development washdev2020156, 2020-04-08)Safe water storage is critical to preserve water quality, especially when intermittent piped drinking water supply creates a need for household storage. This study characterized household storage practices and stored water ... -
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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Hydroclimate projections for Panama in the late 21st Century
(2013-03-31)This work analyzes hydroclimate projections in Panama toward the end of the 21st century by employing the MRIAGCM3.1 model. Understanding the impact of climate change on water resources is fundamental for a number of economic ... -
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 ... -
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 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 ... -

(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 ... -
Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus
(2014-04-24)Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different ... -
Genetic diversity and connectivity remain high in Holothuria polii (Delle Chiaje 1823) across a coastal lagoon-open sea environmental gradient
(2010-07-11)Coastal lagoons represent habitats with widely heterogeneous environmental conditions, particularly as regards salinity and temperature, which fluctuate in both space and time. These characteristics suggest that physical ... -
