7α-methyl-19-nortestosterone (MENT) is an androgen with potent gonadotropin inhibitory activity and prostate-sparing effects. These attributes give MENT advantages over testosterone as a male contraceptive, but, as in the case of testosterone, a partial dose-dependent suppression of spermatogenesis has been observed. Combination of testosterone or MENT with synthetic progestins improves the rat...

The wind environment around a building influences human lives and the design of it. Simulation by CFD software is a main method used to study wind environment. But the reliability of the simulation result needs to be proved by comparing to the measured wind environment data. Experiment and simulation on wind environment were carried out in this reasearch. What’s more, different simulation metho...

We deene a compositional labelled transition system semantics for statecharts via a translation into a new process language called SP. The main novelty of the language is an operator of process reene-ment, which reeects the statecharts hierarchical structure. The translation agrees with Pnueli and Shalev semantics of statecharts. However, since the language is parametric in the set of basic act...

Juvenile male M. a. ater cowbirds, who have never heard other male cowbirds sing, develop distinctively different repertoires when housed with M. a. ater females from their own area versus M. a. obscurus females from a distant population. Because female cowbirds do not sing, the differences in the males' songs do not arise through vocal imitation. Here we provide data demonstrating that the son...

Chromatin condensation to heterochromatin is a mechanism essential for widespread suppression of gene transcription, and the means by which a chromatin-associated protein, MENT, induces a terminally differentiated state in cells. MENT, a protease inhibitor of the serpin superfamily, is able to undergo conformational change in order to effect enzyme inhibition. Here, we sought to investigate whe...

У статті розглядається структура словотвірних рядів слів із суфіксом -ment. Автор аналізує ряди з погляду їх гомогенності та гетерогенності, складності глибини. Словотвірні об’єднано відповідно до класу слів. Класи виокремлено за допомогою реляторної мови аплікативної породжувальної моделі, яка використовується для дослідження R-структури похідних R=словам штучної відповідають L=слова природньо...

The analysis of programs by the exhaustive inspection of reachable states in a nite state graph is a well-understood procedure It is actually implemented in several industrial tools but one of their main limitations is the size of the memory needed to exhaustively build the state graphs of the programs. For numerous properties such as B uchi acceptance (in the deterministic case) and behavioral...
