Development and optimisation of fast, efficient, quantitative, economic and environmentallyfriendly analytical extraction techniques for the extraction clean up, and pre-concentration in the quantification of 16 USEPA priority polycyclic aromatic hydrocarbons ...

In this paper, soil samples collected from three different dumping site located in Ojota, Oke Afa and Solous Lagos were examined to systematically study the speciation of cadmium and lead in dumpsite soil which allows a distinction to be made between residual ...

The purpose of this handbook is to provide Geotechnical Engineers with a guide to the proper procedures in the performance of geotechnical activities for the Florida Department of Transportation. Specifically, this handbook is intended to define the tasks ...

<p>Due to the globalization of the world economy and the global increase of trade, there is an increasing shipment of goods, which creates high demands on the maintenance and development of an efficient infrastructure (roads, railways and waterways). The development ...

The main purpose of the reports is to provide comprehensive descriptions of the state of the art of decision analysis and sampling strategies for contaminated land. The reports form an important basis for future work, not only in the specific project, but ...

<p>Recent records of seismic site response have documented a salient liquefaction-induced cyclic shear-deformation mechanism. During liquefaction, these ground acceleration records have suggested a possible strong influence of soil-skeleton dilation at large ...

A method is presented for calculating the seismic response of a system ofhorizontal soil layers. The essential element of the method is a rheological model suggested by Iwan which takes account of the nonlinear hysteretic behavior of soils and has considerable ...

The paper presents the historical development of fundamental concepts related to the modelling of the non-linear and irreversible behaviour of soils. The concepts of failure, flow rule, successive yield surfaces and hardening rules are recalled. The original ...
