A large class of Laboratory, Space, and Astrophysical plasmas is nearly collisionless. When a localized energy or particle sink, for example, in the form radiative cooling spot black hole, introduced into such plasma, it can trigger plasma thermal collapse, also known as quench tokamak fusion. Here we show that electron conduction collisionless follows convective transport scaling itself its sp...

A simple and reproducible HPLC method with spectrophotometric detection was developed for determination of rivastigmine in human plasma. Liquid-liquid extraction of rivastigmine and donepezil (as internal standard) from plasma samples was performed with 1-butanol/n-hexane (2:98 v/v) in alkaline condition followed by back-extraction into diluted acetic acid. Chromatography was carried out using ...
