Nifuroxazide is an antimicrobial drug from the nitrofuran group, which is used in the treatment of acute bacterial intestinal infections. Its mechanism of action is based on the reduction of the nitro group in bacterial cells, which produces reactive metabolites that permanently damage enzymes and the genetic material of microorganisms. Enzymes of ...

This study explores the potential of Bigpod Sesbania seed oil as feedstock for production of biodiesel. The extracted oil was transformed to biodiesel via transesterification reaction using potassium hydroxide as catalyst. The process variables methanol-to-oil molar ratio (4:1–8:1), catalyst concentration (0.1–0.5 wt%), reaction time (3...

In this work, I aim to examine the various influences of process parameters on the physical andmechanical properties of extruded polystyrene. Since XPS belongs to the group of thermoplasticpolymers, its properties are significantly affected by thermal treatment, particularly temperatureand pressure. However, in addition to these key factors, this p...

The changes in pH and conductivity during the rinsing of the pumpkin peel and the biosorption of Cu2+ ions were the subject of this work. The obtained data showed that the pH value of the solutions increased during the rinsing of the biosorbent, as a result of the transfer of H+ ions from the aqueous phase into the structure of the pumpkin peel. An...
