Meeting Abstract 24.4  Monday, Jan. 5  The hydrodynamics of gill ventilation in teleost fishes STROTHER, J.A.; Univ. of California, Irvine strother@uci.edu The gills of teleost fishes have been described as a model counter-current exchanger. The coordinated movements of the buccal cavity and the opercula drive water through the gills in a direction opposite to that of the […]

Meeting Abstract 24.5  Monday, Jan. 5  Structure and Function of theTurtle Heart Through In Vivo Imaging of Blood Flow WYNEKEN, Jeanette; Florida Atlantic University jwyneken@fau.edu Cardiac structure is quite varied within nonavian sauropsids (reptiles) including shape of the heart, extent of separation of the three intraventricular compartments, degree of development of the intraventricular muscular ridge, and the […]

Meeting Abstract 24.3  Monday, Jan. 5  Modeling blood flow through amphibian hearts using flow visualization and the immersed boundary method HAMLET, C.L.*; MILLER, L.A.; The University of North Carolina at Chapel Hill chamlet@email.unc.edu Amphibian hearts are characterized by three chambers: two thin-walled atria and a single ventricle with a thick, spongy lumen. The left atrium pumps oxygenated […]

Meeting Abstract 24.1  Monday, Jan. 5  Fluid Flow in Physical Models of the Endothelial Surface Layer GUNDERSON, J.A.*; SANTHANAKRISHNAN, A; MILLER, L.A.; Univ. of North Carolina, Chapel Hill jengun@email.unc.edu The purpose of this study is to investigate fluid flow in physical models of the endothelial surface layer by comparing both Newtonian and non-Newtonian fluids. Newtonian fluids are […]

Meeting Abstract 24.2  Monday, Jan. 5  Flow within Physical Models of the Vertebrate Embryonic Heart NGUYEN, NHI / P.*; MILLER, LAURA; SANTHANAKRISHNAN, ARVIND; GUNDERSON, JENNIFER; Univ. of North Carolina, Chapel Hill en08nicki@gmail.com Vertebrate cardiogenesis is believed to be partially regulated by fluid forces imposed by blood flow in addition to myocardial activity and other epigenetic factors. Recent […]

Meeting Abstract 24.6  Monday, Jan. 5  Direct visualization of hemolymph flow in the heart of a grasshopper LEE, W.-K.; SOCHA, J.J.*; Argonne National Laboratory; Virginia Tech jjsocha@vt.edu Most insect circulatory systems are open, consisting solely of a muscular tube that runs from the abdomen to the anterior body. The heart system includes ostial valves, which can effect […]

Meeting Abstract 23.2  Monday, Jan. 5  comparison of attachment performance in the hairy and smooth adhesive pads of insects BULLOCK, J.M.R.*; FEDERLE, W.; University of Cambridge; University of Cambridge jmrb3@cam.ac.uk Despite a strong interest in biomimetic adhesives, the biomechanics of natural adhesive systems are still poorly characterised. Many insects can cling to surfaces via thin films of […]

Meeting Abstract 23.4  Monday, Jan. 5  THE ADHESIVE DISC AND ITS FUNCTIONAL CAPACITY IN NORTERN CLINGFISH Gobiesox maeandricus: Gobiesocidae) AND TIDEPOOL SNAILFISH (Liparis florae: Liparidae): SCALING OF MORPHOLOGY AND SUCTION FORCE MAIE, T*; SUMMERS, AP; Clemson Univ.; Univ. of California, Irvine tmaie@clemson.edu In the intertidal environment, Northern clingfish, Gobiesox maeandricus, and tidepool snailfish, Liparis florae, withstand waves […]

Meeting Abstract 23.5  Monday, Jan. 5  Smart foot secretion – insects dont slip! DIRKS, JH*; CLEMENTE, CJ; FEDERLE, W; University of Cambridge; University of Cambridge; University of Cambridge jhd32@cam.ac.uk Many insects are able to cling to surfaces using adhesive organs on their feet. Adhesion is mediated by thin films of fluid secretion, which help to compensate surface […]

Meeting Abstract 23.1  Monday, Jan. 5  Attachment forces of single adhesive setae from tarantula feet PEATTIE, A M*; FEDERLE, W; Univ. of Cambridge; Univ. of Cambridge ap557@cam.ac.uk Spiders and geckos have convergently evolved dry fibrillar adhesives on their feet that allow them to climb smooth vertical surfaces. These two types of adhesives are materially and morphologically distinct. […]
