Bradoriids, among the earliest arthropods to appear Bertazzoni P755CMODGNE 75cm Modern Series 5 Burner Gas On Glass Hob BLACK in the fossil record, are extinct, ostracod-like bivalved forms that ranged from the early Cambrian to the Middle Ordovician.Bradoriids are notable for having appeared in the Cambrian fossil record before the earliest trilob

One of the legacies of armed conflict is unexploded ordnance and abandoned ammunition.This legacy will, in many cases, have a severe impact on Lunge Line society and daily life, even for years or decades after hostilities have ended.The millions of tonnes of explosive remnants that remain in nature represent a grave threat in many ways, and, if lef

Abstract 329 We study the chameleon field dark matter, dubbed scalaron, in F (R) gravity in the Big Bang Nucleosynthesis (BBN) epoch.With an R 2-correction term required to solve the singularity problem for F (R) gravity, we first find that the scalaron dynamics is governed by the R 2 term and the chameleon mechanism in the early universe, which ma

Grey wolf optimizer (GWO) is a very efficient metaheuristic inspired by the hierarchy of the Canis lupus wolves.It has been extensively employed to a variety of practical applications.Crow search algorithm (CSA) is a recently proposed metaheuristic algorithm, which mimics the intellectual conduct of crows.In this paper, a hybrid GWO with CSA, namel

Friction is ubiquitous and plays a key role in the functionality of many biological and engineering systems, from articular cartilage to machinery.While friction facilitates motion, it also causes wear and energy loss in moving parts.Lubricants (particularly liquid lubricants) are essential to reduce the negative effects of friction, and their prop
