This paper describes the ultrasound-guided transvaginal method of oocyte collection in cattle. Both technical and physiological aspects affecting the efficiency of the method are presented. The results of the author's experiments on oocytes collection and their developmental competence is also discussed.

We report the first application of sublimation molecular beam epitaxy to grow uniformly and selectively doped Si:Er layers with Er concentration up to 5×10^{18} cm^{-3}. The Hall concentration of electrons is about 10% of total Er contents. The mobility is 300-400 cm^{2} V^{-1} s^{-1} at 300 K. All samples exhibit photoluminescence at 1.537 μm up to 100-140 K.
