Determinacion de indicadores para la calidad del agua y sedimento marino no costero en la bahia de manzanillo
(2014-06)El Índice de Calidad de Agua (ICA) es una herramienta utilizada para conocer los atributos de un cuerpo de agua de acuerdo a sus distintos usos; sin embargo, su aplicación se ha dado principalmente en aguas continentales, ... -
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 ... -
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 ... -
Estudio experimental de la ductibilidad de soportes de hormigón convencional sometidos a compresión y carga lateral cíclica
(2009-12)Los soportes de hormigón armado que forman parte de una estructura sismorresistentes en lugares donde existen mayores riesgos de sismo, deben diseñarse con el objetivo de asegurar un adecuado comportamiento en cuanto a ... -
Estudio teórico de capacidad de deformación de soportes esbeltos de hormigón armado con fibras de acero sometidos a esfuerzos combinados de axil y carga lateral
(2012-10)El estudio de la ductilidad es muy importante en elementos estructurales sometidos a esfuerzos combinados, ya que nos determina la capacidad de resistencia y a la deformación. Actualmente son escasos los ensayos experimentales ... -
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ... -
Experimental Validation of the Structural Fuse Concept
(2008-06-30)Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for ... -
Floor Response of SDOF Systems with Metallic Structural Fuses
(2004-06-26)The floor demands of Single-Degree-of-Freedom (SDOF) systems designed or retrofitted with metallic structural fuses are studied in this article. Floor velocity and acceleration are obtained and comparisons are made between ... -
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 ... -
Geophysical Investigations in the Old Panama Archaeological Site
(2006-06-28)The results of geophysical prospections in an archaeological site of hispanic type in Panama (Central America) are presented in this article. The archaeological site of Old Panama has been intensively investigated with the ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Influencia de la presión en roturas de tubería de redes de distribución
(2016-09-01)Uno de los síntomas del deterioro de las redes de distribución de agua son las frecuentes roturas de tubería. Las gestoras del agua tratan de evitarlas en la medida de lo posible debido a los elevados costos económicos, ... -
