Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Sequences of Residues in Algebraic Number Fields [PDF]
, 1995 We define ΛF(n, m) for all integers n, m and an algebraic number field F to be the least positive number such that for almost all prime ideals p there are m consecutive nth power residues in the algebraic number field F with norm less than ΛF(n, m)[F : Q]

New decidable fields of algebraic numbers [PDF]
Proceedings of the American Mathematical Society, 1979 A formally real field of algebraic numbers is constructed which has decidable elementary theory and does not have a real closed or p -adically closed subfield.

Business Strategy and the Environment, EarlyView.ABSTRACT This study provides an exploratory, descriptive analysis of how knowledge management (KM) research engages with responsible sustainability from a strategic perspective. Using bibliometric science mapping, we analyse 97 Web of Science publications to identify dominant thematic patterns, relative emphases and conceptual blind spots shaping the ...

Wilson's map operations on regulat dessins and cyclotomic fields of definition [PDF]
, 2009 Dessins d’enfants can be seen as bipartite graphs embedded in compact orientable surfaces. According to Grothendieck and others, a dessin uniquely determines a complex structure on the surface, even an algebraic structure as a projective algebraic curve ...
