Drugs and chemical compounds are often modeled as graphs in which the each vertex of the graph expresses an atom of molecule and covalent bounds between atoms are represented by the edges between their corresponding vertices. The topological indicators defined over this molecular graph have been shown to be strongly correlated to various chemical properties of the compounds. In this article, by...

Galactic chemical evolution (GCE), solar analogues or twins, and peculiarities of the composition with respect to twins are inextricably related. We examine GCE parameters from literature present newly derived values using a quadratic fit that gives zero for Solar age (i.e., 4.6 Gyr). show how may be used not only "correct" abundances age, but predict relative elemental as function age. address...

The study of the phase space multidimensional systems is one central open problems in dynamical systems. Being able to distinguish chaoticity from regularity nonlinear systems, as well determine subspace which instabilities are expected occur, also an important field. To investigate these, diverse chaos indicators have been developed. information provided these understand behaviour many celesti...

One of the most critical issues faced by chemical industries is reducing environmental impact caused due to pollution, which has resulted in global warming and health issues. Most monitor use Key Performance Indicators (KPIs) control currently done using various KPI’s that are dependent on product they producing. Therefore, a study conducted systematic literature review (SLR) focused articles p...
