THE EFFECT OF PH ON THE SIMULTANEOUS DETERMINATION OF SULFAMETHOXAZOLE AND TRIMETHOPRIM BY ULTRAVIOLET SPECTROPHOTOMETRY AND MULTIVARIATE CALIBRATION

Drug Analytical Research, 2017
Analytical techniques based on Ultraviolet (UV) spectrophotometry are widely used in pharmaceutical analysis, because they are simple and inexpensive. The choice of pH is critical in the development of univariate methods for pharmaceutical quantitation ...

An Insight into the Electronic, Optical and Transport Properties of a Half Heusler Alloy: NiVSi

East European Journal of Physics, 2022
The half-Heusler alloy NiVSi is investigated theoretically by using first-principles calculations based on the density functional theory (DFT). For a better description of the electronic properties, the TB-mBJ potential is used for exchange-correlation ...

Ultraviolet properties of f(R)-Gravity [PDF]

, 2007
We discuss the existence and properties of a nontrivial fixed point in f(R)-gravity, where f is a polynomial of order up to six. Within this seven-parameter class of theories, the fixed point has three ultraviolet-attractive and four ultraviolet ...

Habitable Zones and UV Habitable Zones around Host Stars

, 2010
Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along.
