Significant applications of SrTiO3 single crystals in electronics require knowledge about the influence structural imperfections on their optical properties. Birefringence temperature changes were investigated a few broad range, from 85 K to 250 K. The birefringence was found be non-linear function below transition Ts at 105 K, and indicatrix orientation accompanied it. A weak residual permanen...

Introduction In the modern poultry production, the birds are exposed to different stressful factors. Oxidative stresses produce free radicals suppressing the bird performance by disordering the body homeostasis. The liver is the best tissue to evaluate the oxidant-induced oxidative stresses. CCl4 is an important service today as a toxic agent model to induce oxidative stress on animals leading ...
