STUDY OF COMMERCIAL ADDITIVE EFFECTS ON THE POLY(METHYL METHACRYLATE) EXPOSED TO GAMMA IRRADIATION BY VISCOSIMETRIC ANALYSIS

Study of Commercial Additive Effects on the Poly(methyl methacrylate) Exposed to Gamma Irradiation by Viscosimetric Analysis

Poly(methyl methacrylate) (PMMA) is a polymer with applications in the medical and aerospace industries that Aromatherapy require resistance to gamma radiation.However, the effects caused by gamma radiation on PMMA properties may make its application in situations of exposure to gamma radiation unfeasible.In this study, the impact of commercial add

Time matters! Developmental shift in gene expression between the head and the trunk region of the cichlid fish Astatotilapia burtoni

Abstract Background Differential gene expression can be translated into differing phenotypic traits.Especially during embryogenesis, specific gene expression networks regulate the development of different body structures.Cichlid fishes, with their impressive phenotypic diversity and propensity to radiate, are an emerging model system in the genomic
