Multi-order fractional nonlinear evolution equations system

open access: yesPartial Differential Equations in Applied Mathematics
In this paper, the existence and uniqueness of a solution to a multi-order fractional nonlinear evolution equations system are studied by applying Banach’s Fixed Point Theorem and some properties of solution operators associated with the system.

A note on global existence for boundary value problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
Upper and lower solutions are used in establlsning global existence results for certain two–point boundary value problems for y‴=f(x,y,y′,y″) and y(n)=f(x,y,y′,...,y(n−1)).

Improving the learning experience in an undergraduate course on microbial metabolism by using an illustrated story

open access: yesBiochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 131-141, March/April 2025.
Abstract In the classroom, metabolism is often approached and received as a mundane exercise in memorization. Teaching metabolism also faces the challenge of negative perceptions that can impede learning. We sought to improve the learning experience in an undergraduate lecture course on microbial metabolism by implementing an illustrated story that ...

Preventing and Recovering Food Waste in Manufacturing Firms: A Contingency Perspective on Circular Economy Practices

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Food waste is a sustainability concern in the food industry, which can be mitigated through a circular economy. Circularity can be limited by contextual constraints, such as the characteristics of the waste to be recovered. However, their study in the context of food waste is scarce.
