As is well known, the sound-speed profile has significant effects on underwater acoustic sound propagation. These effects can be quantified by normal-mode models, for example. The basic case is a laterally homogeneous medium, for which the sound speed and the density depend on depth only and not on horizontal position. Effects of horizontal medium-parameter variation can be quantified by couple...

what we mean by alliteration of homogeneous words is that such alliteration is based on two or more lexical basis that is conspicuously coordinative and homogeneous with each other. they are homogeneous in that their form, structure, and tone, are similar. we can name two homogeneous words, two bases of homonym. it is evident that such words, though homogeneous from one hand, should necessarily...
objective: although much is known about estrogen and progesterone, their toxicity or protective effects on hepatocytes are yet to be fully understood. this study investigated the probable oxidant or antioxidant effects of estrogen and progesterone on hepg2 cell line in the presence or absence of h2o2. methods: hepg2 cells were cultured with two concentrations of estrogen and progesterone (10pm ...
