Chemie Ingenieur Technik, EarlyView.Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Upper Bounds for Double Roman Domination and [k]-Roman Domination of Cylindrical Graphs Cm☐Pn [PDF]
Roman-type domination parameters form an important class of graph invariants that model protection and resource allocation problems on networks. Among them, $[k]$-Roman domination provides a unified framework that generalizes Roman, double Roman, and ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This work presents a simplified extended‐batch adsorber analogue model (e‐BAAM) to quantify key performance metrics such as purity, recovery, and energy trends for various pressure swing adsorption (PSA) process cycles for CO2$$ {\mathrm{CO}}_2 $$ capture.

On the outer independent total double Roman dominating functions
Let $\{0,1,\dots, t\}$ be abbreviated by $[t].$ A double Roman dominating function (DRDF) on a graph $Γ=(V,E)$ is a map $l:V\rightarrow [3]$ satisfying \textrm{(i)} if $l(r)=0$ then there must be at least two neighbors labeled 2 under $l$ or a neighbor $r'$ with $l(r')=3$; and \textrm{(ii)} if $l(r)=1$ then $r$ must be adjacent to a vertex $r'$ such ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Recent regulatory initiatives, including the EU Corporate Sustainability Reporting Directive (CSRD), are reinforcing the demand for more structured, transparent, and accessible sustainability reporting. However, empirical evidence on how digital tools influence the narrative dimension of these disclosures remains limited.

Total and Double Total Domination Number on Hexagonal Grid
, 2019 In this paper, we determine the upper and lower bound for the total domination number and exact values and the upper bound for the double-total domination number on hexagonal grid H m , n with m hexagons in a row and n hexagons in a column ...

On The Total Roman Domination in Trees [PDF]
, 2019 A total Roman dominating function on a graph G is a function f : V (G) → {0, 1, 2} satisfying the following conditions: (i) every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2 and (ii) the subgraph of G induced by ...

On the Quasi-Total Roman Domination Number of Graphs
, 2021 Domination theory is a well-established topic in graph theory, as well as one of the most active research areas. Interest in this area is partly explained by its diversity of applications to real-world problems, such as facility location problems ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.
