Reduction kinetics of ceria surface by hydrogen
(
Wiley Periodicals, Inc.
, 2004 , Article)
Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm−3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ...
Factors influencing determination of shale classification indices and their correlation to mechanical properties
(
Springer Verlag
, 2006 , Article)
The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ...
Comparative study on the behavior of square foundations resting on confined sand
(
Canadian Science Publishing
, 2009 , Article)
The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ...
Stability analysis and charts for slopes susceptible to translational failure
(
Canadian Science Publishing
, 2006 , Article)
The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ...
A technique for estimating permeability of a randomly fractured rock mass
(
Springer Verlag
, 2007 , Article)
Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ...
