Extracellular potentials from action potentials of anatomically realistic neurons and neuronal populations.
(2005)Extracellular potentials due to firing of action potentials are computed around cortical neurons and populations of cortical neurons. These extracellular potentials are calculated as a sum of contributions from ionic ... -
Extractive from seven African medicinal plants.
(2003)This PhD thesis describes a phytochemical investigation of seven medicinal plants, namely, Ledebouria ovatifolia (Hyacinthaceae), Eucomis pole-evansii (Hyacinthaceae ), Lachenalia rub ida (Hyacinthaceae), Drimia ... -
Extractives from eucomis montana and agapanthus inapertus.
(2003)Two species belonging to different families were investigated, Eucomis montana from the Hyacinthaceae and Agapanthus inapertus from the Agapanthaceae. To date no previous chemical investigation on Eucomis montana has ... -
Extractives from marine organisms.
(2000)The study involves the investigation of the chemical composition of some marine organisms. This entails collecting the organism, extracting compounds from it and separation, characterization and identification of these ... -
