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 ... -
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 ... -

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" ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
