Quantum chemical studies of mercaptan gas detection with calcium oxide nanocluster.

The electronic sensitivity and adsorption behavior for mercaptan natural gas of a CaO nanocluster were studied via ab initio computations. To be more specific, to fully grasp the influence of mercaptan molecules on the chemical and electronic features of CaO nanocluster, some parameters, namely, charge transfer of natural bond orbital, molecular electrostatic potential, binding energies, and frontier molecular orbitals, are computed. The interaction between CHS molecule and calcium atoms of CaO nanocluster through the sulfur head is strong.

A Questionnaire-Based Survey to Assess the Level of Knowledge and Awareness about Drug-Food Interactions among General Public in Western Saudi Arabia.

Various drug-food interactions exist that may hinder treatment and can sometimes be lethal. Our aim was to assess the level of public knowledge and awareness in Jeddah city, Western Saudi Arabia, about drug-food interactions, along with the effects of demographics on their knowledge. A survey questionnaire was administered in this cross-sectional study to participants spread across multiple locations in Jeddah, including in malls and public gatherings.
