The aim of this study was to evaluate the potential of black cumin essential oils to reduce the degradation of rapeseed oil during heating. Rapeseed oil was heated without addition and with the addition of black cumin essential oil (200 ppm, 500 ppm, and 1000 ppm), and with synthetic antioxidant TBH...

Introduction: the work presents a new complex concept of ore-oil-gas-genesis, where the logical connection shows the role of endo- and exogenous factors in the formation of various minerals, including oil and gas. This concept will help in identifying new hydrocarbon fields in the regions represente...
