Along with foam drainage, the Wglob decrement leads to the instability of foams. But the asphaltenes in drainage liquid would have enough time to be adsorbed on foam film at the lower layer foams; and the lower foams adsorbed more asphaltenes than upper foam due to more drainage flowed ...
The conceptual basis of this model is different from others in that it combines equations of diffusive processes with equations of paint film adherence (competitive adsorption) at the metal surface. The corrosion process is considered to arise through boundary conditions for the diffusion equations ...
The values of the three types of polarization are generally small and stable under normal-temperature environments and low discharge rates. However, they increase significantly in low-temperature environments and at high discharge rates and continue to rise during the discharge process. Additionally, ...
Because pressure is force per unit area, any pressure in the fluid naturally leads to acceleration. (Think of Newton's second law, F = m a.) The second term, called the pressure term, represents this acceleration.DiffusionFrom experience with real fluids, you know that some fluids a...
intergranular and transgranular fractures can lead to charge separation with the crack developing. The intergranular fracture refers to the gradual fracture alongside the facet of the particle prompted by nearby stress heterogeneity, which destroys the intermolecular force and leads to electric potential cha...
But I had difficulty understanding it. So I decided to dive into the model and worked out all the derivations. In this article, I will focus on the two main obstacles to understand the paper: why is the denoising diffusion model designed in terms of the forward process, the forward ...

increasing the shape parameter (k) from exponential to log-normal leads to a decrease in the extinction probability given an infection initiated with a number of infectious virions. Hence, the distribution of the infectious phase duration is also expected to affect the likelihood that an infection...
This limiting situation is called molecular streaming or Knudsen flow, and it is characterized by the fact that the flow takes place by diffusion, instead of viscous, mechanisms [50]. Here, the term diffusion means that the flow results from creep at the wall rather than from molecule-to-...
The process becomes even more intricate for other most promising thermal-efficient or flux-enhanced configurations such as vacuum air gap (VAGMD);25 the diffusion of water in the air (Dw-air), the convective heat in the gap zone, the vapor condensation effect (Qcond) and the heat transfer...
