Peristaltic flow of a Newtonian fluid through a porous medium in a vertical tube under the effect of a magnetic field
Heat Transfer Magnetic Field Newtonian Fluid Porous Medium Reynolds Number
2015/7/21
In this paper, we studied the effects of heat transfer and magnetic field with peristaltic flow of a viscous incompressible Newtonian fluid through a porous medium in a vertical tube under the assumpt...
Regulation of the actin cytoskeleton in the pollen tube
Pollen tube ovule sperm plant sexual reproduction actin cytoskeleton protein
2014/12/11
Pollen tube growth, the process that transports the sperm cell to the ovule, is fundamental for plant sexual reproduction. The actin cytoskeleton is essential to the process of pollen tube elongation....
Albert Einstein and the Fizeau 1851 Water Tube Experiment
Albert Einstein the Fizeau 1851 Water Tube Experiment History and Philosophy of Physics
2012/4/24
In 1895 Hendrik Antoon Lorentz derived the Fresnel dragging coefficient in his theory of immobile ether and electrons. This derivation did not explicitly involve electromagnetic theory at all. Accordi...
The Szego kernel for non-pseudoconvex tube domains in C^2
Szego kernel non-pseudoconvex domains Complex Variables
2011/8/31
Abstract: We consider the Szeg\"o kernel for non-pseudoconvex domains in C^2 given by \Omega = {(z,w): Im w > b(Re z)} for b a non-convex even-degree polynomial with positive leading coefficient. This...
Performance of a 20-in. photoelectric lens image intensifier tube
First generation image intensifier tube Large sensitive area Photodetector High energy astrophysics Ashra Experiment
2011/9/13
We have evaluated a 20-in. photoelectric lens image intensifier tube (PLI) to be mounted on the spherical focal surface of the Ashra light collectors,where Ashra stands for All-sky Survey High Resolut...
On the automorphism group of tube type real symmetric domains
Jordan algebra Jordan triple system bounded symmetric domain partial Cayley transform
2011/1/18
The aim of this note is to explain a generalization to the real case of a well known result on the automorphism group of an unbounded tube type symmetric domain in a complex vector space of finite dim...
Mathematical analysis on MHD pulsatile flow of blood through a rough thin-walled elastic tube
Pulsatile two-phase flow Elastic tube Phase velocity
2010/9/27
In this paper, the effect of an externally applied uniform transverse magnetic field on pulsatile flow of blood containing particles through a rough thinwalled elastic tube has been studied. The inter...
Resonant cyclotron acceleration of particles by a time periodic singular flux tube
cyclotron particles periodic singular flux tube
2010/11/8
We study the dynamics of a classical nonrelativistic charged particle moving on a punctured plane under the influence of a homogeneous magnetic field and driven by a periodically time-dependent singu...
We give a geometric model for a tube category in terms of homotopy classes of oriented arcs in an annulus with marked points on its boundary. In particular, we interpret the dimensions of extension gr...
Separation of Optical Isomers in Capillary Chromatography Using a Poly(tetrafluoroethylene) Capillary Tube and an Aqueous–Organic Mixture Carrier Solution
Separation Optical Isomers in Capillary Chromatography tetrafluoroethylene
2010/9/13
Capillary chromatography for the separation of optical isomers was developed using an untreated poly(tetrafluoroethylene) capillary tube and a water–hydrophilic/hydrophobic organic solvent mixture as ...
Analytical Conditions and Separation Performance of Capillary Chromatography Based on the Tube Radial Distribution of Aqueous–Organic Mixture Carrier Solvents under Laminar-Flow Conditions
Analytical Conditions Separation Performance Capillary Chromatography Based
2010/9/14
We have developed a capillary chromatography system using an open capillary tube made of fused-silica, polyethylene, or poly(tetrafluoroethylene), and a water–hydrophilic–hydrophobic organic mixture c...
Capillary Chromatography Based on Tube Radial Distribution of Aqueous–Organic Mixture Carrier Solvents: Introduction of Double Tubes Having Different Inner Diameters to the System

2010/9/20
A tube radial distribution chromatography (TRDC) system was previously developed using an open capillary tube and an aqueous–organic solvent (water–acetonitrile–ethyl acetate) mixture as a carrier so...
D and Ds in mass loaded flux tube
flux tube model diquark charmed mesons charmed strange mesons
2009/12/24
Heavy-light hadrons are studied in a mass loaded flux tube model. The study indicates that the dynamics of mesons and baryons containing a c quark is described well by the mass loaded flux tube. The h...
