    Description: Endocast analysis of the brain Homo floresiensis by Falk et al. (Reports, 8 April 2005, p. 242) implies that the hominid is an insular dwarf derived from H. erectus, but its tiny cranial capacity cannot result from normal dwarfing. Consideration of more appropriate microcephalic syndromes and specimens supports the hypothesis of modern human microcephaly.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, R D -- Maclarnon, A M -- Phillips, J L -- Dussubieux, L -- Williams, P R -- Dobyns, W B -- New York, N.Y. -- Science. 2006 May 19;312(5776):999; author reply 999.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Field Museum, Chicago, IL 60605-2496, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16709768" target="_blank"〉PubMed〈/a〉

    Notes: Abstract We describe experimental results on the extensional viscosity of mobile polymer solutions obtained from two instruments, the first being a commercial Spin Line Rheometer and the second a custom-built lubricated-die Converging Flow Rheometer. The interpretation of data in terms of Trouton ratios is facilitated by a simple analysis for the Generalized Newtonian Fluid model. Agreement between data from the two rheometers is satisfactory and we show that polymer solutions can be either tension stiffening or tension thinning. However, the Trouton ratios in both cases are greater than the Newtonian values and we anticipate that this will always be the case for polymer solutions.
