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) ...
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 ...
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 ...
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 ...
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 ...
Seismic Response of Single-Degree-of-Freedom Systems with Structural Fuses
(2004-06-25)
Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this article, metallic dampers are defined to be structural fuses (SF) ...
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 ...
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 ...
Seismic Design of Multi-story Buildings with Metallic Structural Fuses
(2006-06-28)
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 ...
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 ...
