While laser-induced fluorescence is a promising nonintrusive method for measuring scalar concentration profiles (Distelhoff et al.), this technique needs to be further developed in order to become a fully quantitative method for mixing processes in three-dimensional (3-D) laminar flows.
Zalc, et al. [34] explored laminar flows in a multiple-impeller stirred tank using state-of-the-art CFD tools, and to extend the analysis to include short and long-time mixing performance as a function of the impeller speed.
Several researches using reactors, viscous fluid and stirring patterns relevant to this study are as follows: Wulandari, et al. [32] found that mixing time for the exothermic reaction of glycerin nitration had been influenced by perturbations applied to fluid mixing.
Zalc, et al. [34] used CFD analysis for laminar flow in a stirring tank with three Rushton turbines.

In 2010, Cherian et al. (2010) has isolated nanocellulose from pineapple leaf fibers by steam explosion.
In 2018, Abral et al. (2018) reported that nanocellulose successfully prepared from pineapple leaf fibers via high-shear homogenization and ultrasonication [20].

We have
previously reported the catalytic cracking of low density polyethylene employing Mexican natural mordenite zeolite and Al-MCM-41 and Ga-MCM-41 materials [17].
We can compare results with those previously obtained at the same reaction conditions, by thermal cracking (pyrolisis) and by catalytic cracking with Al-MCM-41 and Ga-MCM-41 materials [17].
The main gas products obtained with Al-MCM-41 and GaMCM-41 were isobutene and propylene.
While Al-MCM-41 and Ga-MCM-41 produced a large gasoline yield [17], the HPA-MCM-41 catalyst produced a large proportion of fuel oil, followed by gas oil and then, gasoline and kerosene.

Evaluations of Mixed Formulation
This section evaluates the mixed formulation with two case studies using the cantilever reinforced concrete column tested by Bousias et al. [7]: monotonic pushover analysis and cyclic loading analysis.
It uses the general Menegotto-Pinto (GMP) model [9] modified by Filippou et al. [2] for the reinforcing steel with yield strength fy of 460 MPa, Young modulus Es of 210000 MPa, and hardening ratio of 1.4%.
The bond-slip relation does not have a softening branch, since the softening behaviour was not observed in the test by Bousias et al. [7].
The second case study demonstrates the remarkable accuracy of the mixed formulation by correlating the numerical results with the experimental results conducted by Bousias et al. [7].

The paper presents an application in which a two-objective approach involving cost minimization and resilience maximization is adopted for the new design of Sidi Al Hamri water distribution system (Libya), a new city of nearly 75000 inhabitants to be realized in the Green Mountain region.
New design of Sidi Al Hamri water distribution system (Libya) The design of Sidi Al Hamri water distribution network follows the principles of economic and environmental sustainability, and aims at providing a system characterized by an optimal trade-off between cost and reliability, in order to supply high quality water to all customers with an adequate level of pressure under all demand conditions (including fire protection needs).
Pareto front obtained after 2000 generations for Sidi Al Hamri water distribution system.

Jha et al [7, 8] have investigated structural phase transformation and equation of states of CaX (X= S, Se, Te) and SrSe, SrTe, BaSe, BaTe using three body interaction (TBI) potential.
The structural, electronic and elastic properties of SrX (X: S, Se, Te) compounds have been calculated from first principle by Khenata et al [11].
Also, augmented-sphrerical wave method within local density approximation (LDA-ASW) by Carlsson and Wilkins [12] for BaS, BaSe and BaTe, tight binding linear muffin orbital (TB-LMTO) by Kalpana et al [13], linear muffin tin orbital (LMTO) by Syassen et al [9].
Recentaly, Bouhemadou et al [14] have used the full potential augmented plane plus local orbitals method (FP-APW+lo) and reported the structural, electronic, elastic and high pressure properties in these compounds.

This observation aligns with the findings of Werken et al. [15], reported that exceeding the well-dispersed content of carbon reinforcement in a polymer matrix, leads to agglomeration.
Our findings are consistent with the observations reported by Sengupta et al. [16].
