Cell membranes resist flow [PDF]
Cell, 2018 SUMMARY The fluid-mosaic model posits a liquid-like plasma membrane, which can flow in response to tension gradients. It is widely assumed that membrane flow transmits local changes in membrane tension across the cell in milliseconds. This conjectured signaling mechanism has been invoked to explain how cells coordinate changes in shape,

Characterization of Fluid Flow and Heat Transfer of Expanded Metal Meshes for Catalytic Processes
Energies, 2022 In this work, three raised expanded metal meshes (EMMs) differing in mesh size were tested experimentally with regard to their flow and transport properties. Empirical equations for the Nusselt number and Fanning friction factor were developed. Alongside

Study on the Influencing Factors of the Atomization Rate in a Piezoceramic Vibrating Mesh Atomizer
Applied Sciences, 2020 On the basis of previous study in our research group, the phenomenon of the dynamic tapered angle was founded, the occurrence of atomization is regarded to derive from the combined effects of the dynamic variation of the micro-tapered aperture, and the ...

Snarks with Resistance $n$ and Flow Resistance $2n$
The Electronic Journal of Combinatorics, 2022 We examine the relationship between two measures of uncolourability of cubic graphs – their resistance and flow resistance. The resistance of a cubic graph $G$, denoted by $r(G)$, is the minimum number of edges whose removal results in a 3-edge-colourable graph.

Impact of Xiaolangdi Reservoir operations on flow resistance in the Lower Yellow River
Shui kexue jinzhan, 2023 Since the Xiaolangdi Reservoir (XLD) operation, bed materials coarsening and changes in flow resistance have been occurring substantially in the Lower Yellow River (LYR).Thus, to quantitatively describe the effects of XLD on flow resistance in the LYR ...
