The knowledge on the non-Newtonian fluid flow behavior in inflatable and collapsible elastic tubes is important to applications such as biofluid mechanics in human body and the transport of food and liquids in pharynx (throat), esophagus and intestines. The ultrasound Doppler based velocity profiles are measured at a fixed position from the outlet of a horizontal collapsible elastic tube immers...

We examined whether the attentional focus induced by a suprapostural task has an influence on the learning of a dynamic balance task. Participants balanced on a stabilometer and were required to hold a tube horizontal with both hands. In Experiment 1, the tube contained a table tennis ball, whereas it was empty in Experiment 2. Participants were instructed to focus on either their hands (intern...

Introduction The film boiling reactor (FIBOR) is analyzed to show the influence of radiation across the vapor film on product yields. The geometry is that of a horizontal, catalyst-coated, tube suspended in a pool of saturated methanol at atmospheric pressure. The vapor film surrounding the heated tube is the reacting volume and surface reactions are treated with an Arrhenius form of the reacti...
