Comparison of PMAT Camera Holder with Human Camera Holder

In the usual method of suturing, the needle is grasped by the needle-holder which is held more or less in the palm of the hand. The fine, sharp needles of ophthalmic surgery, such as those made by Grieshaber, inevitably become dulled as they are grasped by the metal blades of the needle-...
متن کاملOn Generalized Holder Inequality
A FAMILY of inequalities concerning inner products of vectors and functions began with Cauchy. The extensions and generalizations later led to the inequalities of Schwarz, Minkowski and Holder. The well known Holder inequality involves the inner product of vectors measured by Minkowski norms. In this paper, another step of extension is taken so that a Holder type inequality may apply to general...
متن کاملA Set of Collets for Manipulating the Specimen Holder of the Siemens Electron Microscope
The modification of the Siemens electron microscope grid-holder suggested by Elbers (1) among its other advantages reduces contamination by reducing the handling of the specimen holder either with the fingers or using paper tissue or other fabrics. By using the set of collets described here such handling is entirely eliminated although the operations involved in changing the specimen may still ...
