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...

One of the new methods of anchoring steel structures is the use of large-scale buckling-restrained braces (BRBs) on the lateral system of this type of structure. This study investigates the behavior of BRBs and compares them with buckling braces. In this study, a two-dimensional frame with four stories and four spans was taken and analyzed in eight...

Improving the quality of iron ore sintering and adding specific components has positive effects on blast furnace productivity. Optimizing basicity in the blast furnace charge is one way to improve all indices of production processes. Adjusting basicity aims to achieve the formation of new phase compounds that are favourable for the metallurgical an...

Plastic has become indispensable since its introduction in the late 1800s, valued for its flexibility, durability, and affordability. Global plastic production has grown exponentially, reaching 400.3 million metric tons in 2022, despite a temporary decline in early 2020 due to the Covid-19 pandemic. However, only 9% of all plastics ever produced ha...

This study evaluates three hybrid electrocoagulation (EC) processes with aluminium electrodes:EC-zeolite process (EC+Z), EC-zeolite-ultrasound-assisted process (EC+Z+US), and EC-zeolitemagnet-assisted process (EC+Z+MAG) for compost wastewater treatment with a large content oforganic matter. The focus was on evaluating the effects of these processes...
