Non-Empirical BEM Corrections Relating to Angular and Axial Momentum Conservation

Energies, 2019
The Blade-Element Momentum (BEM) model for Horizontal-Axis Wind Turbines (HAWTs), although extremely useful, is known to be approximate due to model formulation insufficiencies, for which add-ons and corrections have been formulated over the past many ...

Variable Pitch Darrieus Water Turbines

Journal of Fluid Science and Technology, 2008
In recent years the Darrieus wind turbine concept has been adapted for use in water, either as a hydrokinetic turbine converting the kinetic energy of a moving fluid in open flow like an underwater wind turbine, or in a low head or ducted arrangement ...

A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

Clinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

Non‐uniform velocity distribution effect on the Betz–Joukowsky limit

Wind Energy, 2012
ABSTRACTA simple analytic correction is derived for the maximum efficiency of an ideal wind turbine rotor, the Betz–Joukowsky limit. The analytic correction accounts for the effect that the non‐uniform atmospheric boundary layer velocity distribution has on the Betz–Joukowsky derivation.

Harnessing Diversity: Majority‐Group Acculturation Predicts Creativity and Flourishing Over Time

European Journal of Social Psychology, EarlyView.
ABSTRACT Creativity and flourishing are core aims of higher education (HE) institutions and government initiatives globally. Large‐scale projects have linked creativity and flourishing with cultural diversity, yet their associations with majority‐group acculturation (i.e., how members of dominant culture groups adopt minority‐cultural elements and/or ...

In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

Pest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Comprehensive analysis of microtubule‐inhibiting herbicides reveals shared subcellular phenotypes and distinct resistance profiles

Pest Management Science, EarlyView.
Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...
