Distinct Populations of Primary and Secondary Effectors

Abstract. RNA interference (RNAi) is a phylogenetically widespread gene-silencing process triggered by double-stranded RNA. In plants and Caenorhabditis elegans, two distinct populations of small RNAs have been proposed to participate in RNAi: “Primary siRNAs” (derived from DICER nuclease-mediated cleavage of the original trigger) and “secondary siRNAs” [additional small RNAs whose

P&Q University Lesson 7- Crushing & Secondary Breaking : Pit

With impact crushing, the stone breaks along its natural cleavage lines, resulting in a more cubical product, which is desirable for many of today’s specifications. HSI crushers can be primary or secondary crushers. In the primary stage, HSIs are better suited for softer rock, such as limestone, and less abrasive stone.
