Numerical Investigation by Cut-Cell Approach for Turbulent Flow through an Expanded Wall Channel

Axioms, 2023
The expanded wall channel backward-facing step (BFS) and axisymmetric diffuser plays an important role in the society of fluid dynamics. Using a cut-cell technique is an established new method to treat the inclined wall of an axisymmetric diffuser.

Targeted Cell Wall Degradation at the Penetration Site of Cowpea Rust Basidiosporelings

Molecular Plant-Microbe Interactions, 1997
Basidiospore germlings of the cowpea rust fungus (Uromyces vignae) penetrate the epidermal cell wall of the nonhost plant Vicia faba. In order to characterize the wall structure of the penetration site, leaves were high pressure frozen, freeze ...

A comparison of three ways to assemble wall-to-wall maps from distribution models of vegetation types

GIScience & Remote Sensing, 2021
Distribution modeling methods are used to provide occurrence probability surfaces for modeled targets. While most often used for modeling species, distribution modeling methods can also be applied to vegetation types.

An Experimental Study of the Effect of a Small-Scale Rectangular Canal’s Wall Roughness on the Flow Patterns in a 90° Sharp Bend with a Radius of Curvature to the Bottom Width Ratio of 2 [PDF]

مهندسی منابع آب, 2014
The wetted perimeter’s roughness, the radius of curvature and its ratio to the bottom width affect the flow velocity and its patterns. This laboratory study was conducted in a 90° sharp bend flume with a rectangular cross-sectional area, and the radius ...

Relationship between airway inflammation and remodeling in patients with asthma and chronic obstructive pulmonary disease

European Journal of Medical Research, 2009
Despite a number of important differences in the pathogenesis, course and prognosis of asthma and chronic obstructive pulmonary disease (COPD), these two entities also have common features with airway inflammation being one of them.
