Features. The Immersion mill was invented and patented by Hockmeyer in the 1990s to replace the outmoded horizontal milling technologies and three roll mills that process the feedstock very slowly through the shear zone, are cumbersome to disassemble and clean, are labor-intensive, and are fairly inefficient by modern-day standards.

Abscisic acid primes rice seedlings for enhanced tolerance

Abscisic acid primes rice seedlings for enhanced tolerance

Mar 04, 2019 Abscisic acid (ABA) has been shown to prime rice seedlings for enhanced tolerance to alkaline stress under both greenhouse and field conditions. This study aimed to understand the mechanism of the ABA priming effect. Rice seedlings were grown hydroponically and pretreated with ABA (10 μM) for 24 h, and then subjected to alkaline stress simulated by 15 mM Na2CO3 solution (pH 10.87).

The Anatomy of an End Mill In The Loupe

The Anatomy of an End Mill In The Loupe

Dec 10, 2017 An end mill’s overall reach, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.
