Cryptography In Creative Media

This paper argues the value of a creative approach to encryption. The first part of the text includes a survey of historical and modern examples of encryption in art, writing, and music to demonstrate the merit and purpose of cryptography in creative media. The second portion of the text relates an original musical method of encryption developed by the author. The purpose of this study and development is to identify and provide a creative solution to some musical cryptographic issues. There are many existing problems in other methods of musical encryption that have been produced to date. For example, they are easy to decrypt, are not well applied to long messages, or are too complicated to use for people who do not understand music well. This paper explains why the author’s method is a unique and serviceable solution to these problems, using both visual and auditory examples

Diagnostic uses of nuclear medicine in AIDS

Radionuclide imaging, if applied with an organ system approach, is useful in the diagnosis of the AIDS (acquired immunodeficiency syndrome)-related complex. Specific pathologic processes can be suspected on the basis of uptake patterns. The intensity and pattern of pulmonary uptake and concomitant nonpulmonary uptake of gallium provide guidelines for distinguishing among various opportunistic pulmonary pathogens. Gastrointestinal and extra-gastrointestinal tract uptake of gallium aids distinction among fungal, mycobacterial, and viral infections and neoplasms. Patterns of spleen uptake of technetium-99m sulfur colloid and gallium allow differentiation between neoplasm (Kaposi sarcoma) and infection (with mycobacteria). Skeletal and soft-tissue abnormalities can be characterized and differentiated on the basis of bone scan and other radionuclide scan findings. Thallium uptake in brain tumors (and not in areas of infection) allows brain lesion discrimination. In the proper clinical setting, AIDS nephropathy has a characteristic gallium uptake pattern. Cardiac abnormalities (including functional) can also be assessed with scintigraphy. With knowledge of these organ-specific patterns and with correlative imaging studies, the manifestations of AIDS can be differentiated and appropriate treatment instituted
