Analysis of Short-term Steel Corrosion Products Formed in Tropical Marine Environments of Panama
(2012-07-05)
The phases and compositions of the corrosion products of a mild steel (A-36) and two weathering steels (A-588 and COR 420) formed after 3 months exposure to the tropical marine atmosphere of Panama were examined using FTIR ...
Restricción del Río Caimito para Uso Recreativo según el Índice de calidad de Agua 2004
(2013-07-05)
Debido al crecimiento vertiginoso de las áreas suburbanas por falta de planificación y desconocimiento de la población y su interrelación con el medio ambiente, se contaminan nuestras fuentes de agua potable. El Río Caimito, ...
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 ...
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 ...
Seismic Response of Hybrid Systems with Metallic and Viscous Dampers
(2016-06-27)
Metallic dampers can enhance structural performance by reducing seismically induced lateral displacements, and by reducing inelastic behavior of beams and columns. Limiting story drift also indirectly allows for mitigation ...

(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 ...
Microstructural And Mechanical Study of The Al-20Sn (MASS%) Alloy Processed By Equal-Channel Angular Pressing By Route C
(2013-05-25)
In this work, the feasibility of an Al–20Sn (mass%) alloy to improve its mechanical properties through the Equal Channel Angular Pressing (ECAP) process is presented and discussed. Al–20Sn (mass%) alloy samples with a ...
