NOVEL COMPOSITE MEMBRANES BASED ON CHITOSAN COPOLYMERS WITH POLYACRYLONITRILE AND POLYSTYRENE: PHYSICOCHEMICAL PROPERTIES AND APPLICATION FOR PERVAPORATION DEHYDRATION OF TETRAHYDROFURAN

Pervaporation has been applied for tetrahydrofuran (THF) dehydration with novel composite membranes advanced by a thin selective layer composed of chitosan (CS) modified by copolymerization with vinyl monomers, acrylonitrile (AN) and styrene, in order to improve the bar drain board chemical and mechanical stability of CS-based membranes.Composite m

OBJECTIVES: Arthrocentesis is the simplest surgical intervention for the temporomandibular joint (TMJ).It can be performed on an outpatient basis at a low cost and with low cassis crista morbidity.The objective is to release the articular disc by disrupting the adhesion formed between its surfaces and the mandibular fossa through hydraulic pressure

Abstract Background Grafting is a horticultural practice used widely across woody perennial crop species to fuse together the root and shoot system of two distinct genotypes, the rootstock and the scion, combining beneficial traits from both.In grapevine, grafting is used in essie cause and reflect nearly 80% of all commercial vines to optimize fru
