The aim of this study was to develop a derivative of chitosan as pharmaceutical excipient used in sustained-release matrix tablets of poorly soluble drugs. A water-soluble quaternary ammonium carboxymethylchitosan was synthesized by a two-step reaction with carboxymethylchitosan (CMCTS), decylalkyl dimethyl ammonium and epichlorohydrin. The elemental analysis showed that the target product with...
Abstract Arguably, automation is fast transforming many enterprise business processes, operational jobs into monitoring tasks. Consequently, the ability to sustain attention during extended periods of becoming a critical skill. This manuscript presents Brain-Computer Interface (BCI) prototype which seeks combat decrements in sustained tasks within an system. A brain-computer interface system us...
