We study the two dual notions of prime avoidance and absorbance. generalize classical lemma to radical ideals. A number new criteria are provided for an abstract ring be compactly packed (C.P., every set primes satisfies avoidance) or properly zipped (P.Z., absorbance). Special consideration is given interaction with chain conditions Noetherian-like properties. It shown that a both C.P. P.Z. if...

We describe a new mode of optical lithography called absorbance-modulation optical lithography (AMOL) in which a thin film of photochromic material is placed on top of a conventional photoresist and illuminated simultaneously by a focal spot of wavelength lambda1 and a ring-shaped illumination of wavelength lambda2. The lambda1 radiation converts the photochromic material from an opaque to a tr...

Little progress has been made over the last 30 years for improving attenuation by x-ray contrast agents, in part because the mechanisms of x-ray attenuation are thought to be well understood. We hypothesized that x-ray absorbance can be modulated by altering the interatomic spacing between K-edge attenuating atoms. Iodomethane, diiodomethane, 2,6-diiodo-4-nitroanaline, and diiodobenzene isomers...

the methanol extracts of leaves of bauhinia acuminata (mesf) and their different fractions obtained from modified kupchan partitioning method i.e. methanol, pet ether, carbon tetrachloride, chloroform, and aqueous soluble fractions were subjected to biological screening such as total phenolic content and antioxidant activity screening.the amount of total phenolic content differed in different e...
