In PRIMER, is it possible to downweight certain taxa in multivariate community datasets to reflect uncertainty around identification??

I have a dataset with about 80 different species. As usual, some species are very easy to identify with certainty whereas others are more difficult, which means that I am less certain of my...

Kazimierz A. Orlowski

In the conventional Pfauter machine a planetary gear exists in the kinematic system , and the feeding movement is parallel to the axis of the wheel being cut. In this kinematic system without the planetary gear only machining of wheels with straight teeth could be possible. I have got a textbook on it, however, only in Polish.

Horacio Albertini

I believe it is the same kinematics of any conventional gear Hobbing Machine.

I suggest you read the book "Gear Cutting Tools" from Stephen Radzevich
