Caffeine is regularly used by college students to enhance mood and academic performance. Although high doses confer risk for negative consequences, moderate doses of caffeine may lead to acute improvements in mood and cognitive functioning. Notably, the pharmacological effects of caffeine may be enhanced by expectancy effects. College students may also engage in nonmedical prescription stimulant use for similar purposes, as students expect strong cognitive enhancement from prescription stimulants and consider them to be more efficacious

In this paper, the joint impact of the interior heating and chemical reaction on the double diffusive convective flow in porous membrane enclosures soaked by a non-Newtonian Maxwell fluid is investigated applying linear and nonlinear stability techniques. The porous enclosures are square, slender and rectangular. Using the linear stability analysis, the expression for the critical thermal Rayleigh-Darcy number, above which the convective movement occurs, is derived analytically in terms of associated physical parameters. A nonline
