Half-inverse problems for the quadratic pencil of the Sturm–Liouville equations with impulse
(2021)
In this paper, we consider the inverse spectral problem for
the impulsive Sturm–Liouville differential pencils on [0, π]
with the Robin boundary conditions and the jump conditions
at the point 𝜋������

The effect of stress management training on perceived stress, anxiety and hopelessness levels of women with high-risk pregnancy
(Online 202)
The aim of this study was to investigate the effect of stress management training on the perceived
stress, anxiety and hopelessness levels of women with high-risk pregnancy. The sample of this experimental study consisted ...
ZnO/Al2O3 layered structures deposited by RF magnetron sputtering on glass: growth characteristics, optical properties, and microstructural analysis
(12.07.2021)
In this study, Al2O3 thin films of different thicknesses (50 nm, 100 nm, 150 nm, 200 nm, and 250 nm) were, first, grown using RF
magnetron sputtering technique on glass substrate at 30 °C temperature, with 120Wpower value. ...
Selective extraction and enrichment of 5-hydroymethylfurfural from honey, molasses, jam and vinegar samples prior to sensitive determination by micro-volume UV-vis spectrophotometry
(CADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new method was developed for the extraction/enrichment of 5-hydroxymethylfurfural (5-HMF) from sample matrix prior to analysis. The method is based on the selective formation of the imine adduct and ionpair ...
