Second‐Law Analysis of Mini/Micro Counterflow Parallel‐Plate Heat Exchangers: Optimizing Effectiveness by Minimizing Wall Entropy Production

open access: yesHeat Transfer, EarlyView.
ABSTRACT We present an analytical and numerical study of the entropy production rate in laminar counterflow parallel‐plate heat exchangers, aiming to investigate the interplay between multidimensional wall conduction, entropy production, and the optimum wall conductivity that leads to maximum effectiveness.

Levers of Control: Impact on Innovation

open access: yesJournal of Corporate Accounting &Finance, EarlyView.
ABSTRACT Using structural equation modeling, our study provides evidence for the effects of management control systems on innovation performance and knowledge acquisition within organizations. Our proposed model separates (1) dyadic management controls (“one‐to‐one”) from (2) polyvalent management controls (“one‐to‐team”).

Enumeration of E(s2) $\,E({s}^{2})$‐Optimal and Minimax‐Optimal Supersaturated Designs With 12 Rows, 11q $11q$ Columns and smax=4 ${s}_{{\rm{\max }}}=4$

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT The E(s2) $\,E({s}^{2})$‐optimal and minimax‐optimal supersaturated designs (SSDs) with 12 rows, 11q $11q$ columns, and smax=4 ${s}_{{\rm{\max }}}=4$ are enumerated in a computer search: there are, respectively, 34, 146, 0, 3, and 1 such designs for q=2,3,4,5 $q=2,3,4,5$, and 6.

Effect of protein hydrolysis on the emulsifying properties of collagen and its hydrolysates extracted from leather by‐products

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Background Proteins are widely used as emulsifiers due to their amphiphilic nature. Collagen has been of particular interest due to both its distinctive triple helical structure and unique amino acid arrangement, which gives it strength and stability within the water (hydrophilic) and oil (hydrophobic) domains of the emulsion.
