Business Strategy and the Environment, EarlyView.ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Maize Kernel Composition and Morphology Influences Pericarp Retention During Nixtamalization
Cereal Chemistry, EarlyView.Abstract Background and Objectives Pericarp retention during nixtamalization directly influences masa quality, affecting texture, machinability, and nutritional content of staple foods such as tortillas and chips. Despite its industrial relevance, the underlying kernel traits that govern pericarp retention remain poorly characterized.

ESTRADA INDEX OF GENERAL WEIGHTED GRAPHS [PDF]
Bulletin of the Australian Mathematical Society, 2012 AbstractLet $G$ be a general weighted graph (with possible self-loops) on $n$ vertices and $\lambda _1,\lambda _2,\ldots ,\lambda _n$ be its eigenvalues. The Estrada index of $G$ is a graph invariant defined as $EE=\sum _{i=1}^ne^{\lambda _i}$. We present a generic expression for $EE$ based on weights of short closed walks in $G$.

Counselor Education and Supervision, EarlyView.ABSTRACT This phenomenological study explored the lived experiences of bilingual Spanish‐speaking counselors‐in‐training (BS‐CITs) enrolled in a Spanish internship course within a Bilingual Counseling Certificate program. Participants included nine master's‐level counseling students who completed individual, semi‐structured interviews.

ChemFoodChem, EarlyView.Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...

π‐Extended Salphen Scaffolds Enable CO2 Electroreduction and Singlet Oxygen Generation
Chemistry – A European Journal, EarlyView.New family of π‐extended salen ligands bearing phenylene bridge and tunable phenyl‐based substituents, and their corresponding boron difluoride complexes. Thanks to the extended π‐delocalization over the molecule, the ligands themselves show promising results in electrochemical CO2 reduction to CO, while the complexes act as efficient photosensitizers ...

Bounds of distance Estrada index of graphs
CoRR, 2015 Let $λ_1,λ_2,\cdots,λ_n$ be the eigenvalues of the distance matrix of a connected graph $G$. The distance Estrada index of $G$ is defined as $DEE(G)=\sum_{i=1}^ne^{λ_i}$. In this note, we present new lower and upper bounds for $DEE(G)$. In addition, a Nordhaus-Gaddum type inequality for $DEE(G)$ is given.
