Dietary supplementation with ALLPRO, a DHA source, for Nile tilapia reared under field conditions throughout cold season: Effects on growth performance, carcass and fillet quality, and economic feasibility

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract This study evaluated the effects of dietary supplementation with ALLPRO, a source of docosahexaenoic acid (DHA—C22:6n‐3, 126 g kg−1 dry weight) and nucleotides (5 g kg−1 dry weight), on Nile tilapia farmed in southern Brazil during autumn, winter, and spring.

Incorporation of MoO3 Nanoparticles Into Polypropylene Fibers via Melt Spinning: Investigation of Mechanical, Thermal, and Chromic Properties

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Pure PP and PP/MoO 3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO 3 ) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.
