Low temperature characteristics of dielectric properties for Tl4S3 layered single crystals
The current investigation was fulfilled for insight into the dielectric properties of Tl4S3layered single crystals. The real part of dielectric constant ε׳, imaginary part of dielectric constant ε×´, the dissipation factor tan δ and the alternating current conductivity σac were measured in an applied ac electric field of frequencies extending from 2.5 to 50 kHz. These...

The effect of magnetic water on strength parameters of concrete
A machine for magnetic water treatment is designed and its application on the ions contained in water has been investigated to examine the effect of magnetic water on concrete parameters. Strength parameters of concrete have been studied for more than 104 concrete samples, including the non-magnetic samples (made by ordinary water) and magnetic samples (made by magnetic water), with slump and...

Computational approach for comparative phylogenetic analysis of isolated chromium resistant strain Brevibacterium casei
The isolated (Cr [VI]) resistant bacterial strain was identified as Brevibacterium caseiby 16S rRNA sequencing (Genbank Accession Number: EU781952). The generated sequenced data was used for construction of Phylogenetic tree (MEGA 3.1and clustalw2) and predict the two dimensional alignment of the highly conserved regions. Computational comparative 16S rRNA sequence analysis of the isolated strain with...

A study on the engineering properties of sandcrete blocks produced with rice husk ash blended cement
Sandcrete blocks have been in used in many nations of the world including Nigeria, playing a major role in the building industry. The material constituents, their mix, presence of admixtures and the manufacturing process are important factors that determine the properties of sandcrete blocks. This paper investigates the effects of a partial replacement of cement with rice husk ash (RHA) on some engineering...
