Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
The Canadian Journal of Chemical Engineering, EarlyView.This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

This work systematically extends the framework of Meta-Operational Mathematics to the domain of fuzzy algebraic operations and their inverses. Fuzzy algebraic operations (such as t-norms,s-norms, residuated implications, extension principle, cuts, lifts) and their inverses (generalized inverses, residuated inverses, choice inverses, lift inverses) are ...

A lumped modelling framework for the epoxidation of vegetable oils and fatty acid methyl esters
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Epoxidized vegetable oils and fatty acid methyl esters are promising bio‐based alternatives to phthalates for plasticizer applications. Their synthesis typically involves the reaction of unsaturated double bonds with peracetic acid in a biphasic liquid–liquid system, where the simultaneous occurrence of reaction and phase partitioning makes ...

The life and work of Ernest Sydney Keeping
Canadian Journal of Statistics, EarlyView.Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

This work presents a systematic and complete generalization of Operational Mathematics and Meta-Operational Mathematics to the framework of exterior algebra (Grassmann algebra). The essential features of exterior algebra—the anticommutativity of the wedge product ω∧η = (−1)deg(ω) deg(η)η∧ω, the grading structure, nilpotency (the square of any odd ...

Advancing Mathematics at the Intersection of Operator Theory and Non-Associative Algebra
Journal of Operator and Non-Associative AlgebrasThis editorial introduces the inaugural issue of the Journal of Operator and Non-Associative Algebras (JONAA), a new platform dedicated to research at the intersection of operator methods and non-associative algebraic structures. It highlights the motivations for establishing the journal, emphasizing the growing need for a unified venue where ...

Operational Mathematics in Operator Algebras: A Complete Extension from Numbers to Operators
This work establishes a comprehensive theory of Operational Mathematics within the framework of operator algebras, including both commutative and noncommutative cases. The central idea is to extend the number of repetitions of basic mathematical operations (addition, multiplication, exponentiation, tetration, and higher-order hyperoperations) from ...
