Meeting Abstract S1-5.9  Jan. 6  Unraveling the Link between Muscle Activation Timing and Force BIEWENER, A.A.; Harvard University biewener@fas.harvard.edu The temporal relationship between muscle activation and tension development is critical for studies of muscle recruitment using electromyography (EMG), as well as for how EMGs may be used to interpret muscle function more generally. However, several factors influence […]

Meeting Abstract S1-5.8  Jan. 6  To make a valve you have to put your heart into it MILLER, L. A.; University of North Carolina, Chapel Hill miller@math.utah.edu The embryonic vertebrate hearts develops from a simple heart tube that moves blood with a wave of contraction to a valve and chambered pump through a series of complicated morphological […]

Meeting Abstract S1-5.2  Jan. 6  The effects of morphology on gill ventilation STROTHER, J.A.; Univ. of California, Irvine strother@uci.edu The gills of teleost fish have often been described as a counter-current exchanger, where water flows through the gills in the opposite direction to that of blood flow within the gills. Such counter-current exchange depends strongly on the […]

Meeting Abstract S1-5.3  Jan. 6  The allometry of suspension feeding HUMPHRIES, Stuart; University of Sheffield, UK s.humphries@sheffield.ac.uk Suspension feeders exhibit convergence in feeding morphology due to limits imposed by hydrosol collection mechanisms. Previous cross-group scaling studies have been limited in extent, but here I present results from an investigation based on a dataset of 403 species across […]

Meeting Abstract S1-5.1  Jan. 6  Role Models Play in Biomechanics WESTNEAT, M. W.; Field Museum of Natural History mwestneat@fieldmuseum.org Biomechanics is rich in models: mathematical models, physical models, and role models. Using biomechanical models is one way that role models such as Steve Vogel make a complex subject accessible and fun, and help the rest of us […]

Meeting Abstract S1-5.6  Jan. 6  Flow, temperature and the speed of life ELLERS, O; Bowdoin College, Maine oellers@gwi.net On page one of his seminal work �Life in Moving Fluids� Steven Vogel describes a biologist who �goes forth, thermometer in hand, and measures the effects of temperature on every parameter of life�, perhaps with �Arrhenius abused� in the […]

Meeting Abstract S1-5.4  Jan. 6  Facing Up to the Reynolds Rap: Foiling Faux Pas in Formulation Fouling Forces DENNY, MW; Stanford University, Hopkins Marine Station mwdenny@stanford.edu Reconsideration of the Reynolds-number-dependent drag coefficient of wiffle balls has led to a re-evaluation of velocities associated with breaking waves. Modulated by the topography of rocky shores, local velocities in the […]

Meeting Abstract S1-5.7  Jan. 6  Endothelial Mechanotransduction: Let’s Sugarcoat It! LEIDERMAN, K.M.*; MILLER, L.A.; FOGELSON, A.L.; University of Utah; University of Utah; University of Utah karin@math.utah.edu Endothelial cells line blood vessels in the body and are continuously exposed to blood flow, and thus, fluid mechanical forces such as shear stress. Variations in shear stress magnitude and distribution […]

Meeting Abstract S1-5.5  Jan. 6  Drawing inspiration from insect breathing and heaving conventional wisdom: Convective tracheal and air sac mechanisms in Drosophila visualized with x-ray imaging. HALE, ME*; WATERS, JS; LEE, WK; SOCHA, JJ; FEZZAA, K; WESTNEAT, MW; Univ. of Chicago; Arizona State Univ.; Argonne National Laboratory; Argonne National Laboratory; Argonne National Laboratory; Field Museum mhale@uchicago.edu Since […]
