This is the clear message that emerged from Monday's marathon teach-in...

-The stress intensity factor variation along a semicircular surface law in a three dimensional solid @late) of finite thickness is derived. This is done using a nested alternating procedure which employs the complete analytical solution for an arbitrarily loaded circular flaw embedded in an infinite solid. The method accounts for both the front-surface/backsurface as well as the boundary-crack ...

The purpose of the research is to confirm plurals a furrow cutter with levelers combination machine. Combined machine turns soil layer zone where root system field crops develops by 180°, prepares for planting, and forms an irrigation ditch. combined consists disc knives, reverse-cutting ploughshare housings, roller, thresher levellers. conducted theoretic pilot explore showed height sweeper sh...

To reveal the mechanism of the easy discretization and low damage in kernel dispersal, this paper analyzes the microscopic analysis of beak structures and finds that maxillary outside cells of the beak are dense and hard. Besides, the cuticle wrapping on maxilla of chicken's beak can reduce corn kernels damage in the discrete process of ear. From force test of corn ear, we find that value of x ...
