The synthetic terpolymer of L-glutamic acid60-L-alanine30-L-tyrosine10 (GAT) fails to stimulate development of GAT-specific antibody responses in nonresponder strains of mice, but does stimulate the development of GAT-specific suppressor T cells that inhibit the development of normal anti-GAT antibody responses to GAT complexed to methylated bovine serum albumin (GAT-MBSA). Furthermore, extract...

Aging mechanisms of two polymeric insulation materials that are used widely in nuclear power plant low-voltage cables; cross-linked polyethylene (XLPE) and ethylene propylene rubber/ethylene propylene diene terpolymer (EPR/EPDM), are reviewed. A summary of various nondestructive methods suitable for evaluation of cable insulation is given. A capacitive sensor capable of making local nondestruct...

Thermoplastic elastomers (TPEs), based in PP (Polypropylene) / EPDM (Ethylene Propylene Diene Monomer) have as purpose improving resistance and impact, aiming to a more comprehensive use automotive market, among edifications, construction packaging sectors, due their recyclability properties. is commodity, with high melting point, mechanical low density, posing balance between physical properti...

The deficiency of water sources and the environmental disposal large amounts biomass waste (orange peels) produces economic problems, though its conversion into biochar by a pyrolysis procedure might be used to improve soil productivity. In current study, we investigated performance superabsorbent composite grafted on CMC as low-cost, alternative, biodegradable terpolymer (IPNCB) for retention ...

Polymers based on 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) attract significant attention due to their large water absorption capacity when swollen in water. Poly(AMPS) (PAMPS) hydrogels are usually synthesized via free-radical cross-linking copolymerization of AMPS and a chemical cross-linker aqueous solutions. Owing the covalently cross-linked network structure PAMPS preventing diss...
