Part of the materials used in the chemical industry, metallurgical, machine construction, can be coated, as with time it occurs either a decrease of its properties, or even a process of advanced faulting, because of the stresses suffered.The paper presents the GRAPESEED OIL structure of some composite coatings with the nickel matrix also pointing o

This paper presents a novel steering mechanism embedded in a SOCKS point-the-bit rotary steerable system (RSS) for oilfield exploitation.The new steering mechanism adopts a set of universal joints to alleviate the high alternative strain on drilling mandrel and employs a specially designed planetary gear small tooth number difference (PGSTD) to ach

Wounding in first group, while in second group it was more than 4 weeks.Within the clinical follow up, no complications occurred in the first group, while the second group showed some complications such as infection and abscess formation.Histopathological examination showed formation of granulation tissue in Henna treated group was faster than cont

Previously we presented Swarm v1, a novel and open source amplicon clustering program that produced fine-scale molecular operational taxonomic units Reclosable Bags (OTUs), free of arbitrary global clustering thresholds and input-order dependency.Swarm v1 worked with an initial phase that used iterative single-linkage with a local clustering thresh
