Physical beneficiation of heavy minerals - Part 1: A state of the art literature review on gravity concentration techniques.

The efficiency of physical separation techniques of heavy minerals usually encounters some set-backs. The reason is often not far from the inability to develop suitable mineral characterization strategies in order to comprehend/evaluate certain physicochemical features such as surface chemistry, specific gravity difference, magnetic and electrical responses distributed among the mineral particles. The intense need for the development/advancement of efficient gravity concentration route on heavy minerals, more especially for the recovery and upgrade of fine, near-dense, low-grade heavy mineral deposits cannot be over-emphasized.

Single-molecule analysis of transcription activation: dynamics of SAGA co-activator recruitment.

Transcription activators are said to stimulate gene expression by "recruiting" coactivators to promoters, yet this term fits several different kinetic models. To directly analyze dynamics of activator-coactivator interactions, single-molecule microscopy was used to image promoter DNA, a transcription activator, and the Spt-Ada-Gcn5 Acetyltransferase (SAGA) complex within nuclear extract. SAGA readily, but transiently, binds nucleosome-free DNA without activator, while chromatin template association occurs nearly exclusively when activator is present.
