Modelling the drying of single droplets of aqueous solutions of lactose and of maltodextrin

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract The average temperature of shrinking droplets is obtained from an enthalpy balance considering convection to or from the surroundings and cooling due to evaporation of solvent from the surface. This unique application of the fully implicit backward scheme captures the moisture values at all nodes in the grid, including at the centre and outer ...

Weighted Turán Theorems With Applications to Ramsey‐Turán Type of Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We study extensions of Turán Theorem in edge‐weighted settings. A particular case of interest is when constraints on the weight of an edge come from the order of the largest clique containing it. These problems are motivated by Ramsey‐Turán type problems.

On Bipartite Biregular Large Graphs Derived From Difference Sets

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A bipartite graph G = ( V , E ) $G=(V,E)$ with V = V 1 ∪ V 2 $V={V}_{1}\cup {V}_{2}$ is biregular if all the vertices of each stable set, V 1 ${V}_{1}$ and V 2 ${V}_{2}$, have the same degree, r $r$ and s $s$, respectively. This paper studies difference sets derived from both Abelian and non‐Abelian groups.

A Dichotomy Theorem for Γ ${\rm{\Gamma }}$‐Switchable H $H$‐Colouring on m $m$‐Edge‐Coloured Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Let G $G$ be a graph in which each edge is assigned one of the colours 1,2,…,m $1,2,\ldots ,m$, and let Γ ${\rm{\Gamma }}$ be a subgroup of Sm ${S}_{m}$. The operation of switching at a vertex x $x$ of G $G$ with respect to an element π $\pi $ of Γ ${\rm{\Gamma }}$ permutes the colours of the edges incident with x $x$ according to π $\pi $. We
