at pH 6.5, 7.3, and 8.0 are summarized in Fig. 1. Intermediate results were seen at pH 7.0 and 7.6 (not shown). Immediately after the pH manipulation, the b-crosslaps increased 0.2–6.6% (P .0.05). After 2 days, all samples exhibited a significant decrease of the b-crosslaps concentrations. In the control samples, b-crosslaps decreased by 12% at 37 °C and by 5% at room temperature on the second ...

Over the years, chemists have been known to make a significant contribution to science, and to generate new chemical substances as a result of their professional activities. Over 20 million compounds have been recorded in the literature, however, because of their use in chemical processes and their disposal in waste products, only a smaller number of these compounds are available for furture us...

In the present communication, stochastic comparison of a series (parallel) system having heterogeneous components with random lifetimes and series (parallel) system having homogeneous exponential components with random lifetimes has been studied. Further, conditions under which such a comparison is possible has been established. Keywords—Exponential distribution, Order statistics, Star ordering...
