fetal position during pregnancy
extract in this study, position of fetus were examined in the different weeks of pregnancy and their association with fetus presentation in during labor. the study group included women who had normal condition. the aim of this study include: 1- to determine the distribution normal position of fetus before birth. 2- to determine the possibility of concurrent position of fetus in during preg...
متن کاملSending Message into a De nite Future: Non-Parallelizable Case
We construct a proof of membership protocol that uses log2 t steps to prove an element to have the structure a t (modn) given public values n; a; t where n is the product of two large secret primes. Such a proof serves a concrete basis of trust for a time-lock puzzle scheme and its applications in timed-release cryptography. The achieved efciency expressed in log2 t (number of modulo exponentia...
متن کاملSending Message into a De nite Future: Non-Parallelisable Case
Let n be a large composite number. Without factoring n, the construction or veri cation of element a t (modn) given t < n and (a; n) = 1 can be done in t squarings modulo n. For t n (e.g., t < n 1=3), no lower complexity than t squarings is known to achieve the above task. Moreover, it is not known how to speedup the t squarings via parallelisation of multiple processors. These properties sugge...

متن کاملThe position of the testis during the fetal period. An additional parameter to estimate fetal weight.
PURPOSE To establish a correlation between testicular position and fetal weight, in order to provide an additional prenatal parameter for fetal weight estimation. MATERIALS AND METHODS We studied 288 testes from 144 human fetuses. The fetuses were assessed as regards weight, total length, crown-rump length and foot length. Fetal age was calculated according to the foot length criteria. The po...
