Because such labor is usually repetitive and unchallenging, this reduction has probably not deprived youths of crucial developmental experien...

Furthermore, by using [2, p. 230, (1)] a computable representation for the G-function in (1) (and hence also for F,112(s)) may be given in terms of essentially a linear combination of four hypergeometric functions OF3[b2s2 /16] provided that no two of the parameters {1, 1 1+v-P1v-P) differ by an integer. This result for Fv-112(s) is given (correctly) in [3, p. 353, (9)] so that the proposed int...

objective: to evaluate the adnexal masses with conventional gray scale and color doppler flow imaging and to assess their diagnostic reliability to differentiate benign and malignant adnexal masses. materials and methods: we evaluated 30 patients with adnexal mass. morphological characterization of the mass was done using sassone score. color doppler parameters noted down in each patient and ca...
