Each bar will give a "theoretical wet film thickness" or, in other words, the thickness of the coating that should remain on the drawdown card after application. Even with high manufacturing tolerances, the actual wet film thickness can vary from 50% to 90% of the gap. There are multiple types of bar applicators, their forms and uses are shown ...

Sig alert, Sig-alert or Sigalert in California, as well as other parts of the United States, means an incident that significantly disrupts road traffic.The term was originally the name of a pioneering system of automated radio broadcasts regarding traffic conditions, introduced in the 1950s and named after its inventor, Loyd Sigmon.
Adaptive fluid-infused porous films change states when stretched, allowing for dynamic control over transparency and wettability. They were developed by researchers at Harvard University . [ 1 ] The same team previously invented Slippery Liquid Infused Porous Surfaces (SLIPS) which served as the base technology to control wettability in ...
The sign designation for a state-specific sign includes a "(CA)" after the sign number. The CA MUTCD also defines some state-specific series: [8] Series G: California Guide; Series SG: California Special Guide; Series S: California Special Information; Series SC: California Special Temporary Traffic Control; Series SR: California Special Regulation

The fluid film thickness is much less than the width and length and thus curvature effects are negligible. (i.e. h ≪ l {\displaystyle h\ll l} and h ≪ w {\displaystyle h\ll w} ). For some simple bearing geometries and boundary conditions, the Reynolds equation can be solved analytically.
The journal focuses on fluid dynamics and also covers geophysical fluid dynamics, biofluid dynamics, nanofluidics and magnetohydrodynamics. Its lead editors are Eric Lauga (University of Cambridge) and Beverley McKeon (California Institute of Technology). [1] The journal launched in January 2016 and published its 500th article in 2017.
