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 ...
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, ...
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, ...
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 ...
Spatial genetic structure in the saddled sea bream (Oblada melanura [Linnaeus, 1758]) suggests multi-scaled patterns of connectivity between protected and unprotected areas in the Western Mediterranean Sea
(2016-04-01)
Marine protected areas (MPAs) and networks of MPAs are advocated worldwide for the achievement of marine conservation objectives. Although the knowledge about population connectivity is considered fundamental for the optimal ...
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 ...
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 ...
Climate change and environmental planning: Working to build community resilience and adaptive capacity in Washington State, USA
(07/01/2009)
This work focuses on the efforts being made by King County, Washington to respond to the challenges of global climate change, concentrating on both mitigation and adaptation. King County is a leader in the United States ...
Behaviour of steel-fibre-reinforced normal-strength concrete slender columns under cyclic loading
(2012-03-28)
The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ...
