A method of predicting flow rates required to achieve anti-icing performance with a porous leading edge ice protection system

An analytical method was developed for predicting minimum flow rates required to provide anti-ice protection with a porous leading edge fluid ice protection system. The predicted flow rates compare with an average error of less than 10 percent to six experimentally determined flow rates from tests in the NASA Icing Research Tunnel on a general aviation wing section

Towards a Theory of Practice: Critical Transdisciplinary Multiliteracies

About the book: Education institutions and organizations throughout the world are currently being held accountable for achieving and maintaining historically unmatched standards of academic quality and performance. Accreditation bodies; policy makers; boards of trustees; and teacher, parent, and student groups all place educational institutions and organizations under unprecedented accountability pressures. The aim of this volume is to explore and better understand how these pressures are impacting a broad range of social and cultural issues and, subsequently, how these issues impact student motivation and learnin

Explicit SO(10) Supersymmetric Grand Unified Model for the Higgs and Yukawa Sectors

A complete set of fermion and Higgs superfields is introduced with well-defined SO(10) properties and U(1) x Z_2 x Z_2 family charges from which the Higgs and Yukawa superpotentials are constructed. The structures derived for the four Dirac fermion and right-handed Majorana neutrino mass matrices coincide with those previously obtained from an effective operator approach. Ten mass matrix input parameters accurately yield the twenty masses and mixings of the quarks and leptons with the bimaximal atmospheric and solar neutrino vacuum solutions favored in this simplest version.Comment: Published version appearing in PRL in which small modifications to original submission and a paragraph concerning proton decay appea
