We study the microstructure formation and defects dynamics arising in liquid crystalline polymers (LCPs) in plane shear flow by a inetic–hydrodynamic coupled model. The kinetic model is an extension of the Doi theory with a non-local intermolecular potential, including ranslational diffusion and density variation. LCP molecules are ensured anchoring at the boundary by an additional boundary pot...

Nanochannels of mesoporous silica materials were previously found useful for reducing the tumbling motion of encapsulated biomolecules while leaving the biomolecular structure undisturbed. Here we show that experiments of cw-ESR distance measurement in nano-confinement can benefit immediately from the above mentioned features of sufficiently slow molecular tumbling, enabling more accurate deter...

OBJECTIVE To report a new surgical approach that results in a natural size and contour of the external malformed constricted ear. METHODS A total of 62 consecutive patients with constricted ear underwent surgery between July 1, 2005, and December 31, 2007. Depending on the features and severity of the deformity, the methods of tumbling cartilage flap (CF), free auricular composite graft, or a...

Existing active debris removal methods that require physical contact with the target have applicability limitations depending on the maximum angular momentum that can be absorbed. Therefore, a de-tumbling phase prior to the capturing phase may be necessary. The aim of this article is to study the guidance, navigation and control subsystem of the ‘Eddy Brake’, an active contactless de-tumbling m...

This paper examines the shape dynamics of deformable elastic and viscoelastic particles in an ambient Newtonian fluid subjected to simple shear. The are allowed undergo large deformation, with stress determined using neo-Hookean constitutive relation. We first present a method determine initially ellipsoidal that is extension Roscoe ( J. Fluid Mech. , vol. 28, issue 2, 1967, pp. 273–293), origi...

We present circumstantial evidence that the central region of the edge-on S0 galaxy NGC 4570, which harbors a 150 pc scale nuclear disc in addition to its main outer disc, has been shaped under the influence of a small (∼ 500 pc) bar. This is based on the finding of two edge-on rings, whose locations are consistent with the Inner Lindblad and Ultra Harmonic Resonances of a rapidly tumbling tria...

Bacterial chemotaxis results from the ability of flagellated bacteria to control the frequency of switching between smooth-swimming and tumbling episodes in response to changes in concentration of extracellular substances. High levels of phosphorylated CheY protein are the intracellular signal for inducing the tumbling mode of swimming. The CheZ protein has been shown to control the level of ph...

In high quality industrial processes, the control chart is design based on cumulative count of conforming (CCC) items is very useful. In this paper, the performance of CCC-r chart with variable sampling intervals (CCC-rVSI chart) in the presence ofinspectionerrors isinvestigated. The efficiency of CCC-rVSI chart is compared with CCC-r chart with fixed sampling interval (CC...

The flow behavior of (both low molecular weight and polymeric) liquid crystals is strongly affected by the coupling between the flow and the molecular orientation. Nematic liquid crystals which respond with a time-dependent orientational behavior to an applied steady shear flow rather than a stationary flow alignment are called ’tumbling nematics’. The time-dependent phenomena can be rather com...
