Magnetic heating across the cosmological recombination era: Results from 3D MHD simulations [PDF]
, 2018 The origin of cosmic magnetic fields is an unsolved problem and magnetogenesis could have occurred in the early Universe. We study the evolution of such primordial magnetic fields across the cosmological recombination epoch via 3D magnetohydrodynamic ...

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 ...

The determination of heating value by wood chips of waste cane
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 This work deals with determination of heating value by wood chips of waste cane of seven varieties of grape wine. The results show, that the highest values of heating power has variety Portugais Bleu (16,64 MJ . kg−1) and MOPR (16,39 MJ . kg−1). The wood

Alfvenic Heating of Protostellar Accretion Disks
, 1999 We investigate the effects of heating generated by damping of Alfven waves on protostellar accretion disks. Two mechanisms of damping are investigated, nonlinear and turbulent, which were previously studied in stellar winds (Jatenco-Pereira & Opher 1989a,

Thermal stability of cold clouds in galaxy halos [PDF]
, 1999 We consider the thermal properties of cold, dense clouds of molecular hydrogen and atomic helium. For cloud masses below 10^-1.7 Msun, the internal pressure is sufficient to permit the existence of particles of solid or liquid hydrogen at temperatures ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
