Light Distribution in 3D-Printed Thermoplastics.

Daylight distribution is an essential performance parameter for building facades that aim to maximize user comfort while maintaining energy efficiency. This study investigates the feasibility of using 3D-printed thermoplastic to improve daylight distribution and transmission. To identify how geometry influences light distribution and transmission, 12 samples with various patterns were robotically fabricated.

Susceptibility to tetracycline and erythromycin of Lactobacillus paracasei strains isolated from traditional Italian fermented foods.

The aim of this study was to evaluate the susceptibility of 197 isolates of Lactobacillus paracasei, isolated from Italian fermented products coming from different geographical areas, to tetracycline and erythromycin, two antimicrobials widely used in clinical and animal therapy. Isolation media were supplemented with antibiotics according to the microbiological breakpoints (BPs) defined by European Food Safety Authority (EFSA). Isolates were identified at the species level and were typed by rep-PCR using the (GTG)(5) primer.
