Tubule and cyst formation: lightning strikes twice.
CYST AND TUBULE FORMATION are the basic building blocks of organogenesis for many branched organs, including the kidney. Due to the complexity of metanephrogenesis (the human kidney is composed of more than 20 cell types and 1 million nephrons) (6, 8) and the transitory nature of cyst and tubule formation, relatively little had been known about cyst and tubule formation before the development o...
متن کاملOxide reduction during triggered-lightning fulgurite formation
In this study triggered-lightning induced fulgurites were formed in 99.9% pure binary oxides of manganese (MnO) and nickel (NiO) in order to study oxide reduction mechanisms. The fulgurite formation process involved packing the oxide in PVC holders and using the standard rocket-and-wire technique to trigger a lightning strike through the oxide at the International Center for Lightning Research ...
متن کاملDroplet detachment and satellite bead formation in viscoelastic fluids.
The presence of a very small amount of high molecular weight polymer significantly delays the pinch-off singularity of a drop of water falling from a faucet and leads to the formation of a long-lived cylindrical filament. In this Letter, we present experiments, numerical simulations, and theory which examines the pinch-off process in the presence of polymers. The numerical simulations are found...
متن کامل'To bead or not to bead?'.
In subcuticular wound closure, the use of anchorage beads or knots to maintain opposition of wound edges is a common practice, but can lead to complications. One hundred and one abdominal subcuticular wound closures (44 vertical and 57 transverse) were prospectively studied and assessment of wound swelling was made by measuring the length of exposed suture at both ends of the wound, on successi...
متن کاملLightning Discharge and Fundamentals of Lightning Protection
A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...
