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...

To analyze the co-combustion process of coal and biomass in a steam boiler furnace originally designed for pulverized coal combustion, it is crucial first to investigate the dynamic behavior of particles within the aero-mixture channels. Due to differences in material properties and particle size distributions, the behavior of coal and biomass part...

This study presents the results of applied phytoextraction as a soil phytoremediation method, based on the analysis of selected heavy metal content in soil and plant material. The selected locations where phytoextraction was applied as a phytoremediation method (Gradišće, Podbrežje, and Tetovo) are situated in the city of Zenica, in proximit...

Specific environmental conditions, such as marine environments, often influence steel applications in marine industries. These conditions are commonly simulated using a NaCl solution to simplify the study and eliminate the complexities of seawater's chemical and biological variability. In this study, 42CrMo4 steel samples, a widely utilized materia...

The study investigates the Portevin–Le Chatelier (PLC) effect in the cold-rolled Al-Mg alloy EN AW-5754. The tensile tests were performed on dog bone specimens at test speeds of 10, 20, and 50 mm/min. Digital image correlation (DIC) and infrared thermography were used to monitor strain rate and temperature changes. The results showed a strong...
