linearity

The study validates the HPLC method for quantifying naringin in a grapefruit extract. The demonstrated high accuracy, precision, and reproducibility were achieved with recovery ranging from 99.73% to 100.65%. The method linearity was confirmed by a correlation coefficient of 0.999. These findings have significant implications for grapefruit-based pharmaceutical development.

The understanding of the paradigm of nonlinearity in modern conditions as compared to the linear vision of the world is analyzed, the main components of the advantages of the nonlinear approach in armed conflicts are shown, the connection of the nonlinear approach to the conduct of hostilities with the victories of the Armed Forces of Ukraine over the aggressor’s troops in the conditions of a full-scale war of the Russian Federation against Ukraine is substantiated.

The content of USA building standards was analyzed. The comparison of building standards in USA and Russia was done. Similarities and differences were defined. Important defects of building seismic standards in USA were detected.

It is proposed to execute control of transverse cutting form and linearity of geometrical axis of rotary kilns’ frame by electronic devices. Use of them enhance operativeness and accuracy of measurement.
