The recent rise in media use has prompted researchers to investigate its influence on users’ basic cognitive processes, such as attention and cognitive control. However, most of these investigations have failed to consider that the rise in media use has been accompanied by an even more dramatic rise in media multitasking (engaging with multiple forms of media simultaneously). Here we investigat...

A new technique for the sodium dodecyl sulfate-polyacrylamide gel electrophoretic separation of rat skeletal muscle myosin heavy-chain (MHC) isoforms is presented. This technique allows for the separation of the four identified MHC isoforms known to be present in adult rat skeletal muscle. These types of MHC are commonly called I, IIa, IIx or IId, and IIb. The procedure can be performed using m...

Current DNA electrophoretic solutions employ high ionic concentrations and require long electrophoretic run times. Here we demonstrate that high and low molecular weight double-stranded DNA, single-stranded DNA (ssDNA), and RNA can be separated rapidly in agarose-based low-molarity conductive media. Separation of small DNA fragments was optimized by substituting 1-mM solutions of alkali metals ...

A novel hydrate-based method is proposed for separating heavy metal ions from aqueous solution. We report the first batch of experiments and removal characteristics in this paper, the effectiveness and feasibility of which are verified by Raman spectroscopy analysis and cross-experiment. 88.01-90.82% of removal efficiencies for Cr(3+), Cu(2+), Ni(2+), and Zn(2+) were obtained. Further study sho...
