9:30 a.m. – 12:30 p.m. When studying for a doctoral degree (PhD), candidates submit a thesis that provides a critical review of the current state of knowledge of the thesis subject as well as the ...

Researchers have investigated the fluid dynamics of Helicobacter pylori (H. pylori) moving through gastric mucus using a 3D model and a magnetic field. H. pylori uses its corkscrew-like tail to move ...

Flow of a number of complex fluids like surfactant mesophases, emulsions and network forming polymers is induced only when the applied stress is more than a specific value, which is called the yield ...

Yield stress fluids (YSFs) often have a complex, nonlinear response to stress. Below the yield transition they deform in a recoverable way, like a viscoelastic solid, but above it the transition is ...

Fluid materials are classified broadly as simple and structured fluids. Simple fluids are materials consisting of a homogenous phase such as a pure substance or a solution. Materials consisting of ...

WASHINGTON, D.C., October 8, 2019 -- During the past 20 years, the oil industry has begun a gradual transition away from light oils, which are being consumed progressively, toward heavier oils. But ...

Mix a designer magnetic powder into oil, water, or glycol, and what do you get? A fast-acting mechatronic fluid perfect for damping or moving variable loads. Jacob Rabinow of the U.S. National Bureau ...

During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous ...
