  • Kato-Katz analysis technique for Soil-Transmitted Helminthiasis (STH)

    In last October’s newsletter, Sterlitech announced the availability of kits for performing the Kato-Katz  analysis technique for Soil-Transmitted Helminthiasis (STH) in field-based applications, signifying the first time that these kits were available from a source in the United States. ...

  • Comparison of linear and non–linear, space frame–raft–soil interaction analyses, by using finite element method

    The objective of the present study is to estimate the realistic displacements and force quantities in the structural members, accounting for their three dimensional behaviour and non–linear constitutive relations of soil. This demands usage of proper constitutive model for soil and its numerical model, which is validated experimentally. A program has been developed in the present work to compare ...

  • Prediction of Expansion Degree for Natural Compacted Clays

    This paper presents a laboratory study aimed at developing a reliable method to predict the expansion degree of clays. The work herein is intended to complement, not replace, existing research in this area. Utilizing test data for 128 natural soils, a regression analysis was performed to assess the use of the liquid limit, the plasticity index, the percent clay, the percent colloids, and activity ...

  • The Bending of a Screw Plate

    The bending of a screw plate may have a considerable influence on the value of soil modulus derived from test results. This paper presents the dimensionless results of a study in which the plate is analyzed by finite elements and the soil is analyzed by integrated Boussinesq theory corrected for embedment in the medium. These results enable correction for the effect of plate bending for a range ...

  • A Nonlinear One-Dimensional Wave Analysis of a Triaxial Soil Specimen

    A fast triaxial shear device (FTRXD) loads cylindrical soil specimens, displacing the top of the specimen downward and axially at a controlled and very rapid rate. Load and displacement at the specimen top and load at the bottom are measured; specimens are subjected to constant confining pressures. Nonlinear, one-dimensional wave analysis of the specimen was undertaken, using finite-difference ...
