It was found that (1) the modeling module can generate rather accurate models for compressive strength and slump for concrete, (2) the optimization module can generate the lowest cost mixtures for wide range of required strength and slump and their combinations, and (3) the dependence of required strength and slump on the design parameters (component contents) meets expectations.
Then, a low-cost mixture was proposed to function as ADS raw materials in treating real plating waters.
By adopting KMG111, nearly a concentration of succinic acid (32.41 g L−1) with a yield of 0.81 g g−1 glucose, could be obtained in a batch fermentation by using the low-cost mixture of Mg(OH 2 and NH3·H2O to replace MgCO3 as the alkaline neutralizer.
The present work describes a novel chance constrained programming approach that minimizes overall cost of mixture while considering quality control issues.
The mixtures were examined based on the rapid chloride permeability test (RCPT), chloride diffusion test, compressive strength (fc), modulus of elasticity (MOE), splitting tensile strength (STS), flexural strength (FS), and cost of mixture per cubic meter.
Firstly, PCL/gelatin nanofibrous scaffold was fabricated by electrospinning using a low cost solvent mixture [chloroform/methanol for PCL and acetic acid (80% v/v) for gelatin], and then the nanofibrous PCL/gelatin scaffold was modified by collagen type I (0.2 1.5 wt.%) grafting.
For a 100 kmol/h hydrogen feed basis, the results showed high investment and operating costs for Mixture (1) with a specific cost of 8.20 $/kg.
In this study, a low-cost laccase mixture was obtained from P. ostreatus culture broth after optimization of laccase production conditions and one-step protein enrichment, as described by Palmieri et al. [ 6].
Planting mixtures may increase management cost, especially when mixture components differ in their responses to other pathogens and pests, and in their crop husbandry requirements.
The object of this study is to propose a methodology to obtain cost-optimized mixtures that meet evaporation and solubility constraints.
