Simulation of olive pits pyrolysis in a rotary kiln plant

Thermal Science, 2011
This work deals with the simulation of an olive pits fed rotary kiln pyrolysis plant installed in Southern Italy. The pyrolysis process was simulated by commercial software CHEMCAD. The main component of the plant, the pyrolyzer, was modelled by a Plug Flow Reactor in accordance to the kinetic laws. Products distribution and the temperature

An inventory of plant species found in gravel borrow pit around Gaborone, Botswana [PDF]

Journal of Ecology and The Natural Environment, 2015
This study sought to establish an inventory of plant species established at three gravel borrow pits around Gaborone, Botswana.At each, plant data were collected from randomly selected 10 x 10 m quadrats within and up to 30 m away from the borrow pits.Species of Acacia were the most numerous in the pits, while more non-woody than woody species were ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
