We investigate cosmological scenarios with spin-gravity coupling. In particular, due to the spin of baryonic and dark matter particles its coupling gravity, they probe an effective spin-dependent metric, which can be calculated semi-classically in Mathisson-Papapetrou-Tulczyjew-Dixon formalism. Hence, usual field equations give rise modified Friedmann equations, extra terms identified as dark-e...

This study used batch adsorption techniques to evaluate the potential suitability of spent coffee grounds as an environmentally friendly adsorbent for the removal of indium ions from aqueous solutions. In addition, we also investigated the effects of process parameters, such as, the solution pH, adsorbent dose, initial concentration of indium ions and the temperature on adsorption performance. ...

introduction in the wastewater treatment industry, the general attentionis mostly paidto the effluent quality standards. regardless of energy consumption, the treatment plants have been designed based on experience rather than the latest scientific findings.the treatment plants are considered as a part of energy equipment which largely consumed electrical energy.thus, electricity is the great p...
