Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

Deep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Enhancing the nutritional profile of de‐oiled rice bran through solid‐state fermentation with Aspergillus oryzae

Food Biomacromolecules, EarlyView.
Abstract An experiment was conducted to explore the impact of fermenting de‐oiled rice bran (DORB) with Aspergillus oryzae on its nutrient composition and anti‐nutritional factors. DORB was inoculated with 7‐day‐old A. oryzae culture grown on potato dextrose agar. The experiment was conducted in triplicate for 120 h, with samples collected at 0, 24, 48,
