Everyday Wear and Tear
Modern encryption of messages relies on “one-way” functions that are easy to compute in one direction but difficult to deconvolute in the other. Pappu et al. (p. 2026) present a physical one-way function based on the pattern generated by scattered laser l ight through a disordered medium. The resultant speckle pattern can be processed into a numeric key of fixed length and may be useful as a se...
متن کاملVariation in the Functional Power of Human Sweat Glands
A method has been worked out for the measurement of the volume of sweat produced by individual glands. A special paper, impregnated with iodine, absorbs water in a uniform way and shows the area of wetting by a sharply defined blue dot. Indirect calibrations showed that 1 cm.(3) of water would form a spot of 700 cm.(2) area, and that this relation of volume to area was a constant one over a wid...
متن کاملThe Ultrastructure and Histophysiology of Human Eccrine Sweat Glands
The electron microscopy of human eccrine sweat glands has been studied before and after stimulation by pilocarpine iontophoresis. The identity of the dark and clear cells in the secretory segment as defined by Montagna et al. (23) was determined by studying serial sections, thin for electron microscopy and thick for light microscopy. Cells with numerous apical secretory vacuoles are termed muco...
متن کاملLipofuscin (aging) Pigment Granules of the Newborn Human Liver
We have observed pigmented cytoplasmic granules, with the characteristic staining properties of lipofuscin (ceroid, "wear-and-tear") pigment, in newborn human liver. The pigment is found at the periphery of the lobule in hepatocytes and some bile ductular cells. It is acid-fast, PAS-positive after diastase digestion, slightly argyophilic and sudanophilic, and markedly Schmorl's- and peroxidase ...
متن کاملMicrowave thermolysis of sweat glands.
BACKGROUND AND OBJECTIVES Hyperhidrosis is a condition that affects a large percentage of the population and has a significant impact on peoples' lives. This report presents a technical overview of a new noninvasive, microwave-based device for creating thermolysis of sweat glands. The fundamental principles of operation of the device are presented, as well as the design and optimization of the ...
