Relatively few introduced crabs are presently known from Australian waters. The present report significantly extends the documented range of the European Shore Crab Carcinus maenas (Linnaeus) and the Fire Crab Pyromaia tuberculata (Lockington) in eastern Australia, based on recently collected specimens now deposited in the Australian museum, Sydney (AM), and old collections in the Macleay museu...

The Indian farming employs 225 million workforce to cover 140 million hectares of total cultivated land. In spite of rapid farm mechanization (e.g., 149 million farm machinery), the vast resource-poor family farming has primary dependence on traditional methods (e.g., 520 million hand tools and 37 million animal-drawn implements are in operation). The work drudgery, the traumatic accidents and ...

Current corn kernel-cob bonding mechanics models (LSD models) uniformly consider the force changes during maize threshing operation as an elastic change, resulting in computational errors of up to 10% or more discrete element simulations. Due inability perform high-precision simulation characteristics operation, core operating parameters thresher (rotation speed component) rely mainly on empiri...
