The mechanism of formation of striae structures in the dust tails of comets is Tracking Roller proposed.There are local active areas on the surfaces of comet nucleus.The formation of striae is indebted to the different rate of dust ejection from active areas depending on that they are located on the sunlit or shaded side Beanbags of the rotating nu
Maritime decarbonization and strict international regulations have forced liner companies to find new solutions for reducing fuel consumption and greenhouse gas emissions in recent years.Green technology is regarded as one of the most promising alternatives to achieve environmental benefits despite its high initial investment costs.Therefore, a sci
Thrombus formation and tissue embedding significantly impair the clinical efficacy and retrievability of temporary interventional medical devices.Herein, we report an insect sclerotization-inspired antifouling PEPPER JACK armor for tailoring temporary interventional devices with durable resistance to protein adsorption and the following protein-med
This article discusses the aims and means of the Byzantine diplomacy at the initial stage of the Council of Constance.Shortly before the opening of the Council, the Roman King Sigismund of Luxembourg and Venice concluded a truce, but the hidden struggle between them continued.At the Council Sigismund had for an object to create the anti-Turkish coa
Numerical simulations are presented to study the stability of gaps opened by giant planets in 3D self-gravitating disks.In weakly self-gravitating disks, a few vortices develop 343 at the gap edge and merge on orbital time-scales.The result is one large but weak vortex with Rossby number -0.01.In moderately self-gravitating disks, more vortices dev
