Further Development of Polyepichlorohydrin Based Anion Exchange Membranes for Reverse Electrodialysis by Tuning Cast Solution Properties.

Recently, there have been several studies done regarding anion exchange membranes (AEMs) based on polyepichlorohydrin (PECH), an attractive polymer enabling safe membrane fabrication due to its inherent chloromethyl groups. However, there are still undiscovered properties of these membranes emerging from different compositions of cast solutions. Thus, it is vital to explore new membrane properties for sustainable energy generation by reverse electrodialysis (RED).

Studies on the human spontaneous electromyelogram (EMyeloG). III. Spontaneous spinal cord activity of the cat relevant to the human spontaneous EMyeloG.

The spontaneous electromyelogram (EMyeloG) was investigated in 16 cats, some after laminectomy and some by a percutaneous intrathecal technique similar to the human approach. Small diphasic negative-positive waves at less than 50 microV, with short durations, were consistently recorded from the posterior aspect of the spinal cord in both laminectomized and intact cats. It was demonstrated that this kind of background activity is mainly located within the posterior halves of the spinal cord and is strictly dependent on the peripheral inputs producing excitability changes in the gray matter of the posterior horn.
