Visually guided flight control in the rainforest is arguablyone of the most complex insect behaviors: illuminationvaries dramatically depending on location[1], and the densely cluttered environment blocksout most of the sky [2]. What visual information doinsects sample for flight control in this habitat? Tobegin answering this question, we determined the visualfields of the ocelli—thought to play
Aqueous dispersions of fluorinated colloidal spheres bearing grafted poly(ethylene glycol) (PEG) are studied as a function of salt and particle concentration with the aim of improving the understanding of interactions among polymer-grafted particles. These dispersions can sustain large concentrations of salt, but crystals nucleate in dilute dispersions when a sufficient Na2CO3 concentration is rea
The Siemens SGT-800 3rd generation DLE burner fitted to an atmospheric combustion rig has been numerically investigated. Pure methane and methane enriched by 80 vol% hydrogen flames have been considered. A URANS (Unsteady Reynolds Averaged Navier-Stokes) approach was used in this study along with the k − ω SST and the k − ω SST-SAS models for the turbulence transport. The chemistry is coupled to t
In this contribution, a modelling framework for functional fatigue in shape memory alloy wires is introduced. The approach is in particular designed to reproduce the effective response determined by experiments as published in, e.g., Eggeler et al. (Mat Sci Eng A 378:24–33, 2004). In this context, the decrease of transformation stresses, the increase of irreversible strains, and the occurrence of
It is increasingly recognized that molecular chaperones play a key role in modulating the formation of amyloid fibrils, a process associated with a wide range of human disorders. Understanding the detailed mechanisms by which they perform this function, however, has been challenging because of the great complexity of the protein aggregation process itself. In this work, we build on a previous kine
Purpose – The purpose of this paper is to explore the brand core and its management over time. The aim is to develop a framework for managing the core of a brand for continuity and change. Design/methodology/approach – A longitudinal case study of the Volvo brand’s core and its management serves as the empirical basis for a qualitative analysis of the “brand core” using rhetorical perspectives. Fi
Purpose – In the last decade, greater attention has been paid to the role of management accounting and control (MAC) in making professional organizations more horizontal. The authors argue that earlier research has not shown how the interrelatedness between professional identities and MAC influences attempts to make organizations more horizontal. In this paper the authors respond to the call for m
The unsymmetrical nature of a new tridentate ligand bis(quinolinyl)-1,3-pyrazole (DQPz) is exploited in a bistridentate Ru(II) complex [Ru(DQPz)2]2+ to elucidate an unexpected dynamic diastereomerism. Structural characterization based on a combination of nuclear magnetic resonance spectroscopy and density functional theory calculations reveals the first quantifiable diastereomerization dynamics fo
