Structure and Function of Human Stratum corneum under Deformation
Dermatology, 2002<i>Background:</i> The stratum corneum (SC) has an important barrier function. The effect of a mechanical stress applied to the SC is controversial on this important physiological parameter. <i>Objective and Methods:</i> To assess both in vitro and in vivo the structure and function of human SC submitted to controlled strains ...

Deformation Analysis of Bending Stratum Based on Displacement Function Method
Geotechnical and Geological Engineering, 2020Bending strata is an inevitable consequence of coal mining, which will waste mineral resources and influence their production. In this paper, the displacement function suitable for curved beam in polar coordinates is introduced, and the partial differential governing equation of curved beam is obtained by theoretical analysis.

Deformation and Filtration Near a Well in a Porous Stratum with Linear Memory
International Applied Mechanics, 2003The linearized equations for saturated elastic porous media and for surrounding elastic rock are solved simultaneously; and the Volterra principle is used to derive an integro-differential filtration equation for a homogeneous weakly compressible fluid in an axisymmetric stratum with linear memory and central well. An analytical expression for porosity

Deformation of transfersomes dispersed in hydrated deep eutectic solvent in stratum corneum
Chemistry LettersAbstract The deformation of transfersomes (TFs) dispersed in deep eutectic solvents and applied to the stratum corneum (SC) was evaluated by small-angle X-ray scattering. We found that TFs permeated the SC, while the regularity and period of the multilayer structure of TFs deformed significantly, depending on the SC location and the time

Recent Advancement in Soil Behavior, in Situ Test Methods, Pile Foundations, and Tunneling, 2009
Sequential excavation method is often used in urban tunnel construction. Based on the stochastic medium theory and according to the stratum deformation caused by element excavation, the stratum deformation united calculating equation under this excavation method is studied, which can take into account the development course of the deformation with the ...
