Heavy metals are highly poisonous in the environment, even in small quantities, and endanger certain species and all live beings. Current methods of removing heavy metals from aqueous media include chemical sequestration, ion exchange, surface absorption, membrane processes, oxidation and revival procedures which have high investment and exploitation costs. Hence, it is significantly necessary ...

Heavy media multitaskers have been found to perform poorly in certain cognitive tasks involving task switching, selective attention, and working memory. An account for this is that with a breadth-biased style of cognitive control, multitaskers tend to pay attention to various information available in the environment, without sufficient focus on the information most relevant to the task at hand....

a bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. in this research bacillus licheniformis strain was identified based on the result of 16s rrna analysis. optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32oc, agitation speed: 20...
