Sturm’s theorems for conformable fractional differential equations
In the present paper, we make use of local properties of the recently established definition of a conformable fractional derivative. Sturm’s separation and Sturm’s comparison theorems are proved for differential equations involving ...

C6-substituted purine derivatives: an experimental and theoretical 1H, 13C and 15N NMR study
We measured the 1H, 13 C and 15N chemical shifts for a series of purine derivatives. The experimental data were complemented with density functional theory (DFT) calculations. The comparison of the calculated and experimental chemical shifts...
