Modelling the Chemical Evolution [PDF]

open access: yesProceedings 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.

Evaluation of mental models of prospective science teachers on chemical reactions [PDF]

open access: yesJournal 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

open access: yesCell & 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).

Reduced-Precision Chemical Kinetics in Atmospheric Models

open access: yesAtmosphere, 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.

A Novel Modelling Process in Chemistry: Merging Biological and Mathematical Perspectives to Develop Modelling Competences

open access: yesEducation Sciences, 2021
Models are essential in science and therefore in scientific literacy. Therefore, pupils need to attain competency in the appropriate use of models. This so-called model–methodical competence distinguishes between model competence (the conceptual part ...

The SIR dynamic model of infectious disease transmission and its analogy with chemical kinetics [PDF]

open access: yesPeerJ Physical Chemistry, 2020
Mathematical models of the dynamics of infectious disease transmission are used to forecast epidemics and assess mitigation strategies. In this article, we highlight the analogy between the dynamics of disease transmission and chemical reaction kinetics ...
