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 ...
Seismic Response of Single-Degree-of-Freedom (SDOF) Structural Fuse Systems
(2004-06-26)
Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this paper metallic dampers are defined to be structural fuses (SF) ...
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 ...
Study of The Corrosion Products Formed on Carbon Steels in The Tropical Atmosphere of Panama
(2003-06-25)
Mössbauer spectroscopy and X-ray powder diffraction (in selected samples) have been used to characterize corrosion products on carbon steels after atmospheric exposure to the tropical Panamanian locations of Panama and ...
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 ...
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, ...
Using the Micro – Resistivity Method to Detect Hispanic Ancient Floors at Nombre de Dios, Panama
(2010-07-02)
This article describes the application of the method of electric prospection to the detection of floors of hispanic type associated with the site of Nombre de Dios. This site represents an important and ancient Spanish ...
Prospección Geofísica Aplicada a la Arqueología – Importancia de los Procesos de Modelización y Simulación Numérica
(2008-06-30)
Los últimos años del siglo veinte se caracterizaron por el desarrollo de grandes proyectos científicos de los cuales conviene mencionar la aparición de medios de cálculo computacionales; estas herramientas permiten ...
