A hypophysis-ovarian system of barren cows was shown to be highly sensitive to the effect of the preparation RL-S. The preparation possessing a simple chemical structure, proved to regulate the functional activity of endocrine glands. After treatment with the preparation RL-S concentration of estradiol was increased 1.81-fold in blood plasma of cows studied as compared with controls, while content of luteinizing hormone was elevated by 12.3%. In the groups of experimental animals the sexual cycle was normalized as content of progesterone was increased in blood with simultaneous decrease in estradiol concentration.

TiO2 visible light catalysts with different crystalline phases and morphologies were synthesized from titanium-bearing electric arc furnace molten slag (Ti-bearing EAF slag) by using a simple acidolysis process. The effects of the pH of the HCl solution, liquid to solid ratio (RL/S, HCl solution to the residue ratio, mL/g) and acidolysis time on the micro-morphology and crystalline phase of as-prepared TiO2 photocatalysts were systematically investigated. The results indicated that with decreasing pH in the HCl solution and increasing RL/S, the crystalline phase and micro-morphology of the obtained TiO2 nanostructures tended to transform from anatase type TiO2 with spherical nanoparticle structures to rutile type TiO2 with needle-like nanorod structures.
