A NEW FOSSIL CRICKET OF THE GENUS PROANAXIPHA IN MIOCENE AMBER FROM THE DOMINICAN REPUBLIC (ORTHOPTERA, GRYLLIDAE, PENTACENTRINAE)

A new fossil cricket of the genus Proanaxipha in Miocene amber from the Dominican Republic (Orthoptera, Gryllidae, Pentacentrinae)

A new species of the cricket genus Proanaxipha Vickery & Poinar (Orthoptera: Gryllidae: Pentacentrinae) from Early Miocene Dominican amber is described and illustrated.Proanaxipha madgesuttonae sp.n.is distinguished from congeners by: (1) head capsule bearing a 7gm pravana distinctive posteriorly bilobed colour spot on the vertex; (2) presence

Study on factors affecting vertical drilling bottom hole assembly performance and a new bottom hole assembly design method considering formation uncertainties

Drilling a deep vertical well at a low cost is very important for accelerating the exploration and development of oil and gas resources.Vertical drilling BHA design is the key to drill a vertical well, however the read more BHA design is still an art not science in some formation.In this paper, a new mechanical model of bent-housing motor BHA is es

Comprehensive Ecological and Geographic Characterization of Eukaryotic and Prokaryotic Microbiomes in African Anopheles

Exposure of mosquitoes to numerous eukaryotic and prokaryotic microbes in their associated microbiomes has probably helped drive the evolution of the innate immune system.To our knowledge, a metagenomic catalog of the eukaryotic microbiome has not been reported from any insect.Here we employ a novel approach to preferentially deplete host 18S ribos
