The garment industry is currently one of the largest industries in Vietnam. In 2021, Vietnam became the second-largest garment exporter in the world after China. Towards decent work and economic growth, garment businesses in Vietnam are very interested in improving productivity and quality, one of the measures is balancing the sewing line. Currently, Vietnamese garment enterprises mainly use the method of line balancing according to experience, leading to the low line balancing efficiency, the line balancing performance is not stable, and the transfers of the semi-finished products between working positions are not optimized. Utilizing the theoretical basis of methods of line balancing, the level of balance of the sewing line has been researched, calculated, and compared based on the evaluation criteria to find the most optimal method. In this research, 5 methods of balancing line are used to balance the t-shirt sewing line in the garment industry in Vietnam and found the most optimal method in 5 methods.

This work aims to synthesize a core–shell material of CeO2@SiO2 based on rice husk as a novel hybridized adsorbent for antibiotic removal. The phase structures of CeO2@SiO2 and CeO2 nanoparticles t...

This study investigated adsorption of beta-lactam antibiotic Amoxicillin (AMX) on a new material of cerium oxide-coated nanosilica (CeO2-coated SiO2). The CeO2-coated SiO2 based on rice husk, was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Adsorption behaviors of AMX on CeO2-coated SiO2 at different pH and ionic strength were thoroughly studied. The highest removal of AMX using CeO2-coated SiO2 reached 99.26 % at pH 4 while the maximum adsorption capacity was found to be greater than 11.0 mg/g. Adsorption isotherms of AMX on CeO2-coated SiO2 at different ionic strength were in accordance with Freundlich model. Adsorption of amphoteric AMX species on CeO2-coated SiO2 increased with a decrease of salt concentration indicating that adsorption was controlled by both electrostatic and non-electrostatic interactions
