Influence of Particle Elongation and Aspect Ratio on the Discharge Behavior of a Flat-Bottom Silo

open access: yesKONA Powder and Particle Journal
Silos are widely used structures designed with hoppers or as flat bottoms to store different types of particulate materials (pellets, grains, powders, etc.). Although they have been used in industry for a long time, further research is needed.

The distribution of settling velocity of non-spherical mineral particles [PDF]

open access: yesActa Montanistica Slovaca, 2005
The settling velocity is an independent variable of the hydraulic separation performed for instance by means of jigs. Therefore, the settling velocity characterizes the material forwarded to the separation process.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

How Sensitive Is the Elasticity of Hydroxyapatite-Nanoparticle-Reinforced Chitosan Composite to Changes in Particle Concentration and Crystallization Temperature?

open access: yesJournal of Functional Biomaterials, 2015
Hydroxyapatite (HA) nanoparticle-reinforced chitosan composites are biocompatible and biodegradable structural materials that are used as biomaterials in tissue engineering. However, in order for these materials to function effectively as intended, e.g.,

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
