The notions of purity and equational compactness of universal algebras have been studied by Banaschewski and Nelson. Also, Banaschewski deals with these notions in the special case of G-sets for a group G. In this paper we study these and related concepts in the category PRO of projection algebras, that is in N∞-sets, for the monoid N∞ with the binary operation m.n = min{m, n}. We show that eve...

Extensive application of silica nanoparticles (SNPs) in various industrial products has led to the development of silica extraction methodologies out of various waste products. Rice husk is an agricultural waste with a high content of amorphous silica. However, the presence of metal ion impurities and unburned carbon in the rice husk content may present an adverse effect on product color and pu...

High-speed counter-current chromatography (HSCCC) has been successfully used for the separation of eight compounds from Chimonanthus praecox flowers. Firstly, the crude extract of Chimonanthus praecox flowers was dissolved in a two-phase solvent system composed of petroleum ether-ethyl acetate-methanol-H₂O (5:5:3:7, v/v) and divided into two parts: the upper phase (part I) and the lower phase (...
