Modelling the Chemical Evolution [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractAdvanced observational facilities allow to trace back the chemical evolution of the Universe, on the one hand, from local objects of different ages and, secondly, by direct observations of redshifted objects. The chemical enrichment serves as one of the cornerstones of cosmological evolution.

Microscopic Models for Chemical Thermodynamics [PDF]
Journal of Statistical Physics, 2005 We introduce an infinite particle system dynamics, which includes stochastic chemical kinetics models, the classical Kac model and free space movement. We study energy redistribution between two energy types (kinetic and chemical) in different time scales, similar to energy redistribution in the living cell.

Evaluation of mental models of prospective science teachers on chemical reactions [PDF]
Journal of Pedagogical Research, 2021 The aim of this study is to examine prospective science teachers' (PSTs) mental models and meanings for the concept of chemical reaction. For this purpose, this study adopted a phenomenological research design including 48 PSTs.

ZSCAN4 interacts with PARP1 to promote DNA repair in mouse embryonic stem cells
Cell & Bioscience, 2023 Background In eukaryotic cells, DNA double strand breaks (DSB) are primarily repaired by canonical non-homologous end joining (c-NHEJ), homologous recombination (HR) and alternative NHEJ (alt-NHEJ).

Chemical modeling of exoplanet atmospheres [PDF]
Experimental Astronomy, 2014 The past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored. Thanks to current observational technologies, we are able to determine some information about the atmospheric composition,

Reduced-Precision Chemical Kinetics in Atmospheric Models
Atmosphere, 2022 Modelling atmospheric composition and climate change on the global scale remains a great scientific challenge. Earth system models spend up to 85% of their total required computational resources on the integration of atmospheric chemical kinetics.
