    Abstract: The present invention is a culture slide assembly having a base member, a cooperable receptacle chamber removably attached to the base and means for separating the chamber from the base. Preferably, the assembly may be used for carrying out biological reactions or growth therein, such as growing tissue or cell cultures.

    Abstract: In examining the progress of patients before and after a cataract operation, the morphology of cornea endothelium cells used in medical treatment, may be determined from a cornea endothelium cell image with less labor. Center points of two-dimensionally continuous cells of a cornea endothelium cell image are entered into a computer, and peripheral points obtained by determining peripheral points which are center points of the cells within a specified distance from one center point are sorted clockwise. If an angle formed by successive two peripheral points and the center point is less than a specified angle, the greater of the two peripheral points in distance from the center point is excluded from the peripheral points. If a distance between the first point and the third point of the obtained successive three peripheral points is shorter than a distance between the center point and the second point, the second point is excluded from the peripheral points, and average distances between the peripheral points and the center point are determined. A perpendicular line that proportionally divides a distance between a center point and its peripheral points by their average distances to the peripheral points is determined for each of the successive peripheral points, and intersection points of the resulting perpendicular lines are determined as vertices of the cells. Thus, morphological data are computed from the obtained vertices.

    Abstract: Apparatus and methods for creating deposits of uniformly spaced or uniformly overlapping droplets of selected chemicals where each droplet has an a priori known amount of the selected chemical or chemicals is taught (including biological and microbial materials). In some embodiments the deposits may be used as samples of different but known concentrations that may be used to calibrate spectroscopic inspection instruments to enable such instruments to not only provide identification in situ of unknown materials but also to provide calibrated and traceable surface concentrations of such materials. In some embodiments, such calibrated instruments may be used in enhanced processes for validating the cleanliness of manufacturing surfaces such as surfaces of equipment used in the preparation of pharmaceuticals, food, or semiconductor devices. Such instruments may be used to ensure adequate purity, or non-contamination, of surfaces of products themselves or packaging materials or of locations where such products will be used. Such calibrated instruments may also be useful in detecting cleanliness of non-manufacturing surfaces where contamination may be of concern, whether they be public or private spaces such as laboratories, restaurants, airports, satellites or other spacecraft. In some embodiments, such instruments may range from deep UV instruments to far infrared instruments or beyond.
