The invention relates to a method and a device for milking milk residues to achieve the extraction of as much of the milk as possible that is preset in the udder. The frame can include a plurality of generally uniformly spaced-apart slats extending between at least two upright members or cross members. Optical sensitivity is achieved through the inclusion of another species of quantum dots whose absorption is generally at longer wavelengths relative to the light-emitting material. The profile values at specified locations are then compared with thresholds or profiles for normal conditions of vagina and its support structures. The strength of such amorphous polymers is enhanced by annealing to increase crystallinity without substantially increasing the biodegradation time. In particular, the present invention is directed to processes for preparing patterns for use in metal castings.
