[A simple technic for the study of the hair shaft cuticle using light microscopy].
Replicas of the hair cuticle can be obtained after application of a small quantity of cyanoacrylate to the hair shaft which is then placed on a glass slide. The hair is quickly removed after 30-40 sec. By this method, it is possible to make an office diagnosis of weathering of the hair surface. The technique is simple, easy to perform and allows a fast examination of a permanent replica of the hair surface.
The present invention relates to a tool for thinning bunches of young berries comprising a cutter head for housing a cutter. The cutter head is constructed with guides to permit the user to excise selected laterals from the main stem of the bunch without nicking or scraping the main stem, or coming into physical contact therewith except at the tip thereof. The tool includes a handle for controlling the cutter head. The handle serves a double function in that it is also a measuring device which permits the worker to nip off the tip of the main stem touched by the worker doing the thinning process, at a predetermined length.
