Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry. [PDF]

open access: yesMass Spectrom Rev
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

Convective layered flows of a vertically whirling viscous incompressible fluid. Velocity field investigation

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
This article discusses the solvability of an overdetermined system of heat convection equations in the Boussinesq approximation. The Oberbeck-Boussinesq system of equations, supplemented by an incompressibility equation, is overdetermined.

Delay of vortex ring pinchoff by an imposed bulk counterflow [PDF]

open access: yes, 2004
The Kelvin–Benjamin variational principle has been previously used to predict that vortex ring pinchoff can be delayed if the energy of the leading vortex ring is decreased during formation and/or the energy delivered by the vortex generator is increased.

Thermal Characteristics of a Primary Surface Heat Exchanger with Corrugated Channels

open access: yesEntropy, 2015
This paper presents the heat transfer and pressure drop characteristics of a primary surface heat exchanger (PSHE) with corrugated surfaces. The PSHE was experimentally investigated for a Reynolds number range of 156–921 under various flow conditions on ...

Counterflows: Hydraulic Order and Residual Ecologies in the Dominican Landscape

open access: yesIberoamericana. América Latina - España - Portugal, 2019
This article argues that transnational capitalism is buoyed up by a “hydraulic order:” a paradigm that advocates unfettered flows of capital, commodities, and people as conduits for development.

Vanishing Hall Resistance at High Magnetic Field in a Double Layer Two-Dimensional Electron System [PDF]

open access: yes, 2004
At total Landau level filling factor $\nu_{tot}=1$ a double layer two-dimensional electron system with small interlayer separation supports a collective state possessing spontaneous interlayer phase coherence.

UPHILL TRANSPORT INDUCED BY COUNTERFLOW [PDF]

open access: yesThe Journal of General Physiology, 1957
1. In a membrane transport system containing a mobile carrier with affinities for two substrates a concentration gradient with respect to one of the substrates under certain conditions is able to induce an "uphill" transport (against the concentration gradient) of the other. 2.

Couette-Hiemenz exact solutions for the steady creeping convective flow of a viscous incompressible fluid with allowance made for heat recovery

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
In this paper, we study the steady creeping convective flow of a viscous incompressible fluid in the thin infinite layer. The study of the fluid flow is based on the exact solutions class for the Oberbeck-Boussinesq equations in the Stokes approximation ...
