background: human immunodeficiency virus (hiv) causes severe immunosuppression due to progressive decrease in the cd4 t lymphocyte cells during the course of the disease and this affects all the body systems including glandular secretions. a number of lesions affecting the salivary glands have been noted in hiv infection. the objective of this study was to evaluate the salivary ph and the buffe...

The problem of reassembling an object from its parts or fragments has never been addressed with a unified computational approach, which depends on the pure geometric form of the parts and not application-specific features. We propose a method for the automatic reconstruction of a model based on the geometry of its parts, which may be computergenerated models or range-scanned models. The matchin...

The existing buffers algorithms cannot effectively to meet the demands of high accuracy buffer analysis in practice although many efforts have been made past 60 years. A generalized buffering algorithm (GBA) is presented, which considers geometric distance and attribute characteristics all instances within zone. proposed includes three major steps: (1) select initialize target instance; (2) det...

For positive constants c and d, the coefficients t and b will always assume values between 0 and 1. Such a buffering behavior, which is also characteristic of H+ buffering in pure water (Buffering II Supplement 2), was classified as “noninverting moderation” (Buffering I). The accompanying paper presented a general method to construct communicating vessel-models of noninverting moderation (Buff...
