Deterioration and corrosion in scoria based blended cement concrete subjected to mixed sulfate environment

The use of blended cements incorporating supplementary cementing materials and cements with low C3A content is becoming common to prevent the deterioration of concrete structures subjected to aggressive environments. This paper presents the results of an investigation on the performance of finely ground volcanic scoria (VS) based ASTM Type I and Type V (low C3A) blended cement concrete mixtures with varying immersion...

Magnetocatalytic adiabatic spin torque orbital transformations for novel chemical and catalytic reaction dynamics: The Little Effect

In this manuscript the theory and some phenomena associated with the Little Effect are introduced as the spin induced orbital dynamics of confined fermions under strong magnetic and thermal environments.  This Little Effect is considered in details for the electron transfer reactions associated with redox processes of Cu-Ag alloy within de-ionized water and for the orbital dynamics during the iron catalyzed...

Adjustable filtering structure design dedicated to a programmable hearing aid apparatus

This research concerns the conception and the development of one specific circuit for a programmable hearing aid. In fact, actual hearing aid prosthesis should be flexible and programmable apparatus to the pathological case. First of all, it must be adjusted according to the pain threshold conserving all dynamics sound. Second, it must be adapted to different patient audiogram levels. In this article, we present the...
