non-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولEvaluation of heavy metal pollution in sediments, water and macrobenthos of Hur Al-Azim wetland (Khuzestan)
Background and Objectives: Chemical storage of water cannot provide complete information about the extent of bioavailability of metals in the environment, while the study of this storage in the chain of water, sediment and macrobenthos can make the rate of rotation and storage risk more visible in ecosystems. Hur Al-Azim wetland is located in the west of Khuzestan Province. Large parts of it ha...
متن کاملPollution Assessment some of Heavy Metals in Water and Surface Sediments of Nasseri Wetland (Khorramshahr)
Background and Aim:This research was conducted of determining and comparing the heavy metals of zinc, iron, manganese, copper, nickel and vanadium in summer in waters and sediments of Naseri wetland in Khuzestan province, 2017. Material and Methods:Sampling of water and sediments from three areas of north, central and southern Naseri wetland was carried out in summer. In order to measure heavy...
متن کاملWater wave-driven seepage in marine sediments
The action of water waves moving over a porous seabed drives a seepage ̄ux into and out of the marine sediments. The volume of ̄uid exchange per wave cycle may aect the rate of contaminant transport in the sediments. In this paper, the dynamic response of the seabed to ocean waves is treated analytically on the basis of poro-elastic theory applied to a porous seabed. The seabed is modelled as ...
متن کاملAssessment of Heavy Metals Pollution in Water and Sediments of Djendjen River, North Eastern Algeria
Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...
