Plastic deformation mechanisms of Polybutylene terephthalate (PBT) are investigated at 120°C, 150°C and 180°C using tensile experiments, 2D digital image correlation, wide small angle X-ray scattering measurements. Plots nominal stress vs true strain (ε), ε Haward-Thackray representation reveal the same I, II, III regimes in ranges virtually independent temperature. Between = 0 yield εY ≈ 0.3 (...

This experiment was conducted to investigate the effect of in ovo feeding (IOF) and dietary feeding of Silybum marianum (SM) extract on the immunity of chicken under heat stress conditions. A total of 360 fertile eggs from a commercial broiler breeder (Ross-308) farm was used for in ovo feeding of 0, 100 and 200 mg/L SM water extract at day 17.5 of incubation. After hatching, 240 chicks were tr...
