Identification and measurement of ELEMENTS and their location based on the fact that X-RAYS emitted by an element excited by an electron beam have a wavelength characteristic of that element and an intensity related to its concentration. It is performed with an electron microscope fitted with an x-ray spectrometer, in scanning or transmission mode.
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
The book composed of writings generally accepted by Christians as inspired by God and of divine authority. (Webster, 3d ed)
'Printing' in a medical context refers to the temporary or permanent transfer of ink from a substrate to the skin, often used for identification purposes, monitoring medical conditions, or as a form of temporary decoration.
Inorganic or organic compounds that contain boron as an integral part of the molecule.
The science of the earth and other celestial bodies and their history as recorded in the rocks. It includes the study of geologic processes of an area such as rock formations, weathering and erosion, and sedimentation. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
The use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Formerly called statistical bibliography. (from The ALA Glossary of Library and Information Science, 1983)
A publication issued at stated, more or less regular, intervals.
Copies of a work or document distributed to the public by sale, rental, lease, or lending. (From ALA Glossary of Library and Information Science, 1983, p181)
General name for two extinct orders of reptiles from the Mesozoic era: Saurischia and Ornithischia.
A hard or leathery calciferous exterior covering of an egg.
##### There does not appear to be a recognized medical term or condition specifically named 'Montana.' I can provide information about the state of Montana, if that would be helpful?
Remains, impressions, or traces of animals or plants of past geological times which have been preserved in the earth's crust.
Warm-blooded VERTEBRATES possessing FEATHERS and belonging to the class Aves.
Unforeseen occurrences, especially injuries in the course of work-related activities.
The study of early forms of life through fossil remains.
