Frictional Drag and Electrical Manipulation of Recombinant Proteins in Polymer-Supported Membranes
Polymers Lipids Recombinant Fusion Proteins Green Fluorescent Proteins Membrane Proteins Electrophoresis Membranes,Artificial Osmosis Histidine Models, Chemical
2016/5/24
We establish a lipid monolayer supported by a polymer interface that offers advantages over conventional solid-supported membranes for determining the frictional drag at the membrane-protein interface...
Drag-out effect of piezomagnetic signals due to a borehole:the Mogi source as an example
piezomagnetic effect borehole magnetic measurement the Mogi model Long Valley
2015/9/2
We show that using borehole measurements in tectonomagnetic experiments allows enhancement of the observed signals. New magnetic dipoles, which vary with stress changes from mechanical sources, are pr...
Effects of blade flexural rigidity on drag force and mass transfer rates in model blades
blade flexural rigidity model blades
2014/11/28
We created a model physical system to investigate the role of blade rigidity in setting forces and rates of mass
exchange for a blade exposed to unsteady flow in a vortex street. Using a combination ...
Influence of bed patchiness, slope, grain hiding, and form drag on gravel mobilization in very steep streams
Influence of bed patchiness slope grain hiding form drag on gravel mobilization very steep streams
2014/4/8
Steep streams are a major portion of channel networks and provide a link to transport sediment from hillslopes to lower gradient rivers. Despite their importance, key unknowns remain, perhaps foremost...
Drag coefficients for single coral colonies and related spherical objects
scleractinian corals drag force coral hydrodynamics
2014/4/1
Flows over and through coral canopies and isolated coral colonies are sometimes approximated using
arrays of spheres and cylinders, which may not adequately represent the effects of their complex geo...
Theory of superfluidity and drag force in the one-dimensional Bose gas
Lieb-Liniger model, Tonks-Girardeau gas, Luttinger liquid, drag force, superfluidity, dynamical structure factor
2011/9/29
The one-dimensional Bose gas is an unusual superfluid. In contrast to higher spatial dimensions, the existence of non-classical rotational inertia is not directly linked to the dissipationless motion ...
Momentum dependence of drag coefficients and heavy flavour suppression in quark gluon plasma
Momentum dependence heavy flavour suppression
2011/7/20
The momentum dependence of the drag coefficient of heavy quarks propagating through quark gluon plasma (QGP) has been evaluated. The results have been used to estimate the nuclear suppression factor o...
Influence of Mutual Drag of Light and Heavy Holes on conductivity of p-Silicon and p-Germanium
Mutual Drag of Light avy Holes
2010/11/25
Conductivity of p-Si and p-Ge is considered for two band model with due regard for mutual drag of light and heavy holes. It is shown that for small and moderate temperatures this drag sig-nificantly d...
Laboratory experiments and numerical simulation reveal that a submerged intruder dragged hor-
izontally at constant velocity within a granular medium experiences a lift force whose sign and
magnitud...
Influence of electron-hole drag on conductivity of neutral and gated graphene
Influence of electron-hole drag gated graphene
2010/11/18
Conductivity of monolayer and two-layer graphene is considered with due regard for mutual drag of band elec-trons and holes. Search of contribution of the drag in conductivity shows that this effect c...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
Technical Note: Sensitivity of 1-D smoke plume rise models to the inclusion of environmental wind drag
1-D smoke plume rise models environmental wind drag Sensitivity
2010/2/1
Vegetation fires emit hot gases and particles which are rapidly transported upward by the positive buoyancy generated by the combustion process. In general, the final vertical height that the smoke pl...
A method for testing drag-reduction on riblet surfaces based on the Spalding formula
Spalding formula riblet surface drag-reduction testing
2011/9/13
This paper presents a method based on the Spalding formula for testing drag-reduction on riblet surfaces. Its advantage lies in that it is more convenient and yields more precise data compared with te...
Numerical Prediction of Wave Drag of 2-D and 3-D Bodies under or on a Free Surface

2009/10/9
The flow characteristics such as; wave drag, lift (if present in the case of 2-D), wave pattern, and pressure distribution around 2-D and 3-D bodies moving steadily under or on a free surface are inve...
Some Problems Associated with Wind Drag and Infrared Images of the Sea Surface
Wind Drag Sea Surface Infrared Images
2009/4/2
It is argued that there should be a close connection between fluctuations in infrared images of the sea and fluctuations in wind drag on the sea. The critical regions of wind speed, temperature, and s...
