Aerodynamic performance of the high-altitude propeller, especially the counter rotation effects, is experimentally studied.Influences of different configurations on a 2 lb m&m bag stratospheric airship, included 2-blade counter-rotating propeller (CRP), dual 2-blade single rotation propellers (SRPs) and 4-blade SRP, are also indicated.This research
A submersible video camera system, which dune obsessive 2 aimed to record the growth image of aquatic vegetation in Antarctic lakes for one year, was manufactured.The system consisted of a video camera, a programmable controller unit, a lens-cleaning wiper with a submersible motor, LED lights, and a lithium ion battery unit.Changes of video camera
Recent fsu headband advancements in animal tracking technology and high-throughput sequencing are rapidly changing the questions and scope of research in the biological sciences.The integration of genomic data with high-tech animal instrumentation comes as a natural progression of traditional work in ecological genetics, and we provide a framework
Abstract Background A new family of natural products has been described in which cysteine, replica grease gun serine and threonine from ribosomally-produced peptides are converted to thiazoles, oxazoles and methyloxazoles, respectively.These metabolites and their biosynthetic gene clusters are now referred to as thiazole/oxazole-modified microcins
