A 6-year-old neutered male German shepherd dog was evaluated for obtundation, blindness, and bilateral exophthalmos. magnetic resonance imaging scan of the brain performed identified an arteriovenous malformation (AVM) with several feeding arterial branches, venous drainage through cavernous sinus. Venous vessels rostral to AVM were severely distended extended into retrobulbar spaces. Liquid em...

In the present study, poly(ethylene-co-vinyl alcohol) with 44 mol % ethylene content (EVOH44) was managed to be processed, for first time, by electrospinning assisted coaxial technology of solvent jacket. addition this, different suspensions cellulose nanocrystals (CNCs), contents ranging from 0.1 1.0 wt %, were also electrospun obtain hybrid bio-/non-bio nanocomposites. The resultant fiber mat...

In this paper, the aqueous copolymer dispersions of methyl (meth)acrylate-grafted poly(vinyl alcohol) are in situ synthesized and studied as a promising platform for deposition thin films with advanced applications. A series varied structure composition obtained at mild reaction conditions by carrying out redox polymerization different monomer-to-PVA ratio initiator concentration. The colloidal...

Ethylene Vinyl Alcohol (EVOH) is a random copolymer of ethylene and vinyl alcohol, commonly used as a barrier to hydrocarbons in automotive fuel systems and agricultural pesticide and herbicide solvents. EVOH provides extremely high resistance to the migration of gases and volatile organic compounds (VOC’s). The incorporation of EVOH in radon resistant new construction has the potential to dram...

The oxygen (O2) barrier properties of ethylene vinyl alcohol copolymer (EVOH) have been widely investigated, but for other gases the available data are usually limited to dry conditions due limitations in measurement equipment. Innovative permeation systems with low detection limits required determine gas transmission rate (GTR) gases, such as nitrogen (N2) at varying temperature and relative h...

Abstract This paper aims to fabricate new superhydrophobic nanocomposite coating materials protect the inner surfaces of petroleum pipelines from corrosion. The batch emulsification polymerization technique (BEM) was used as a facial eco-friendly prepare three hydrophobic (styrene/vinyl acetate) copolymers. sol–gel method SiO 2 nanoparticles (SiO -NPs) with average size ranging 90 101 nm. funct...

In this work, lignin-vinyl acetate copolymers containing different fractions of lignin were synthesized by the copolymerization technique. The copolymer was successfully applied to coat paper for enhancing its properties and performance. effects on physicochemical, air permeability mechanical investigated. strength, hydrophilic, coated improved with increasing content lignin. Lignin-vinyl 15% e...
