Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

Fire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.
