Melanonychia is black or brown pigmentation that appears in the fingernails and toenails. The pigment can come from exogenous sources, such as bacteria or fungal infection, tar, or blood. Endogenous causes include aberrant melanin production in the nail bed, resulting in a longitudinal presentation.

Longitudinal Design and Longitudinal Analysis
Research on Aging, 1986The desirability of longitudinal data is generally accepted among researchers in aging and gerontology. In recent years, a great deal of such data have been collected either in the form of large scale national surveys of more local efforts. Not uncommonly, such data are underanalyzed.

Longitudinal radioisotope tomograph
Biomedical Engineering, 1976To-day the construction of an apparatus for longitudinal emissive tomography has become a problem of great urgency. The designed apparatus, as described herein, is based on the principle of the image superposition method and the results obtained are suggestive of possibilities for its efficient application in diagnosing diseases involving large organs,

Digitized Longitudinal Tomography
Investigative Radiology, 1981An analog video longitudinal tomographic system has been converted to a digital format that reconstructs the tomographic section through the use of matrixes representing the gray scale values of the analog-recorded video images. This was done so that some simple preprocessing could be used to eliminate electronic noise and thereby increase the ...

Psychometrika, 1970
A model is presented for factor analysing scores on a set of psychological tests administered as both pre- and postmeasures in a study of change. The model assumes that the same factors underlie the tests on each occasion, but that factor scores as well as factor loadings may change between occasions.

Longitudinal field studies are in-depth studies of change processes. They are case studies studying a phenomenon over time and often involve real-time studies of organizational phenomena, with the researcher being present in the organization. Research questions often concern how organizational change emerge, develop, grow, or terminate over time ...
