Abstract: The invention relates to a process of making an anti-reflective coating composition comprising the steps of 1) preparing an oil-in-water emulsion by mixing an apolar organic compound A; a cationic addition copolymer C as emulsion stabilizer; and aqueous medium of pH 2-6; at a mass ratio C/A of 0.1 to 2, to result in 1-50 mass % (based on emulsion) of emulsified droplets of average particle size 30-300 nm; and 2) providing an inorganic oxide shell layer to the emulsified droplets by adding to the emulsion obtained in step 1) at least one inorganic oxide precursor, to result in organic-inorganic core-shell nano-particles with mass ratio core/shell of from 0.2 to 25. An advantage of this process is that the dispersion of nano-particles obtained is stable under different conditions, and allows altering its concentration and solvent system, and addition of different binders and auxiliary components.

Abstract: The present invention is made for the prevention of ketosis or minimizing the effects of ketosis in ruminant animals. This purpose is achieved by feeding to the animal biotin in combination with a mixture of at least two essential oil compounds selected from the group consisting of thymol, eugenol, meta-cresol, vaniline and guajacol. The present invention is useful because it is capable of preventing and/or inhibiting ketosis of calving ruminant animals and the subsequent need for veterinary treatment. In a preferred embodiment of a feeding concept for dairy cattle, especially calving dairy cattle, biotin being used in an amount sufficient to provide a daily dosage of 10 mg to 20 mg per head to which it is to be administered. It is at present contemplated that the essential oils are administered in amounts (total dosage ranges of essential oils) of 1 to 1.5 g per head per day.
