By Burgon & Ball Nova-Flore meadow seed mixtures are designed to foster biodiversity and create a haven for bees, butterflies, and song birds.
Both the RTFO (rolling-thin film oven) aging of asphalt binders and the STOA (short-term oven aging) of asphalt mixtures are designed to simulate aging during the construction of hot mix asphalt (HMA) pavements.
Nine mixtures are designed by the Taguchi method considering the factors of sodium carbonate content (SCC), water to solid ratio (WSR), waterglass modulus (WGM) and waterglass content (WGC), and the experimental results are evaluated by applying the analysis of variance (ANOVA) method.
For that purpose, mixtures are designed in a L18 orthogonal array with six factors, namely, "water/cementitious material (W/C) ratio", "water content (W)", "fine aggregate to total aggregate (s/a) percent", "fly ash content (FA)", "air entraining agent (AE) content", and "superplasticizer content (SP)".
The proposed methodology is first applied to the design of solvents and solvent mixtures for maximising the solubility of ibuprofen, often sought in crystallization processes; next, antisolvents and antisolvent mixtures are generated for minimising the solubility of the drug in drowning out crystallization; and finally, solvent and solvent mixtures are designed for liquid liquid extraction.
Twenty LWSCC mixtures are designed and tested, where responses (properties) are evaluated to analyze influence of mix design parameters and develop the models.
