Relevance.Powerful high-voltage synchronous motors with STD and STDP round rotor series oolution light up are the main elements of oil gathering system and maintaining reservoir pressure.This fact increases the operational reliability demands.Vibration condition is one of the key parameters controlled in operation.The vibration sources are mechanic

Assessing spider diversity remains a great challenge, especially in tropical habitats where dozens of species can locally co-occur.Pitfall trapping is one of the most widely used techniques to collect spiders, but it suffers from several biases, and its accuracy likely varies with habitat complexity.In this study, we compared the efficiency of pass

Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of Irritator, Angaturama, and Oxalaia.In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary issues concerning this particular clade of dinosaurs.The me

Cell migration usssa pro m softballs refers to the ability of cells to translocate across a substrate or through a matrix.To achieve net movement requires spatiotemporal regulation of the actin cytoskeleton.Computational approaches are necessary to identify and quantify the regulatory mechanisms that generate directed cell movement.To address this
