Some laterite soil is an inferior material for engineering applications such as road and highway pavement, dam construction filling material. Laterite stabilization required to increase its strength field application purposes. The potential use of zeolite waterglass stabilizing agents their pozzolanic properties. This study aims analyze the bearing capacity stabilized by waterglass-activated re...

Background: Assessment of activity concentrations of 238U, 232Th, 40K and gamma dose rate (DR) was carried out over a laterite mining field in Ilorin-south, Nigeria. Materials and Methods: A well calibrated Super-Spec (RS-125) gamma spectrometer was used to measure the activity concentrations of 40K, 238U, 232Th and gamma doses rate at 1 m above the ground level over the laterite mining field. ...

• A novel biobased material as a potential adsorbent was proposed. Locally sourced used in the composite fabrication. Adsorbents can be removed facile method (magnetically) after adsorption. Biobased enables sustainable and environmentally friendly approach for removing contaminants. Remediation of dye contamination is an important concern countries such Bangladesh whose economy depend heavily ...

An actinomycete strain with a great potential to produce bioactive compounds isolated from a laterite soil was identified as Streptomyces sp. MSL based on 16S rDNA sequence analysis. Secondary metabolites produced by the strain in optimized nutrient broth were extracted and analyzed by chromatographic and spectroscopic techniques. Among the different fractions, four diols, viz., (1) (2R,3R)-2,3...

An attempt was made to study the bioactive compounds from a terrestrial Streptomyces sp. ANU 6277 isolated from laterite soil. Four active fractions were recovered from the solvent extracts obtained from the culture broth of five day-old strain. Three bioactive compounds were purified and identified as 3-phenylpropionic acid, anthracene-9,10-quinone and 8-hydroxyquinoline. The components of the...
