Rocks encountered in foundations of heavy structures are invariably intersected by discontinuities(joints).In the past,several studies have been performed by researchers to incorporate the effect of fully persistent j...
In this study, based on daily gage precipitation data of 2480 stations from 1961 to 2016, the summer (JuneeAugust) extreme precipitationevent was defined using the 95th percentile, and the changes in persistent (la...

AIM: TO estimate the prevalence of the lactase non-persistent genotype (C/C-23910) in a northern Russian population in accordance with ethnicity, and to evaluate self-reported milk consumption depending on lactase ...
We present some conditions such that under these conditions an endomorphism of the circle has nontrivial rotation set and this rotation set changes under small perturbations of the endomorphism. Therefore, we have a c...
