Kinetics of Phenolic Compounds Modification during Maize Flour Fermentation

open access: yesMolecules, 2021
This study aimed to investigate the kinetics of phenolic compound modification during the fermentation of maize flour at different times. Maize was spontaneously fermented into sourdough at varying times (24, 48, 72, 96, and 120 h) and, at each point ...

Optimising zero-order suppression in ion-exchanged phase gratings [PDF]

open access: yesEPJ Web of Conferences, 2020
Ion-exchange in glass is a well-known technique to fabricate phase optical elements. For elements with reduced dimensions, the side diffusion, intrinsic to ion-exchange processes, can affect the performance of these elements if it is not taken into ...

Zero-sum partitions of Abelian groups of order $2^n$ [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
The following problem has been known since the 80's. Let $\Gamma$ be an Abelian group of order $m$ (denoted $|\Gamma|=m$), and let $t$ and $m_i$, $1 \leq i \leq t$, be positive integers such that $\sum_{i=1}^t m_i=m-1$.

BRAIDS, ORDERINGS AND ZERO DIVISORS [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 1998
We begin with the observation that the group algebras [Formula: see text] of Artin's braid groups have no zero divisors or nontrivial units. This follows from the recent discovery of Dehornoy that braids can be totally ordered by a relation < which is invariant under left multiplication.
