Cast iron is an iron‐carbon alloy widely used in mechanical engineering. Nickel‐base or cobalt‐base alloy coatings prepared by laser cladding can improve the surface properties of cast iron, thereby increasing the service life of the components; however, due to the poor weldability and high carbon content of cast iron, the use of laser cladding to ...

Timing by rhythms: Daily clocks and developmental rulers
We compare and contrast two biological "clocks". The circadian clock is used by organisms to regulate their behaviour in time with the 24 hour daily planetary cycle, whereas the segmentation clock appears to be an oscillatory ruler that is used briefly during development to subdivide the body axis into morphological segments.

Machining and Performance Testing of Inclined Double-roller Enveloping Hourglass Worm Drive
To eliminate the gear backlash,a new inclined double-roller enveloping hourglass worm drive is proposed. The meshing performance is analyzed based on the meshing geometry of inclined double-roller enveloping hourglass worm drive.
