The distribulion of adhesive mechanisms in the normal bronchial epithelium. S. Montefort, J. Baker, W.R. Roche, S.T. Holgate. ©ERS Journals Lld 1993. Depts of *Immunopbarmacology and ••Pathology, University of Southampton, Southampton, UK. ABSTRACT: The integrity of the bronchial epithelium is dependent on various adhesion mechanisms that sen-e to bold the composite structure or the epithelium together and anchor it to the underlying basement membrane. Using immunobistochemic;try we wanted to map out a number of these junctional and oon-jundiooaJ adhesion mechanisms in the normal bUD1lUl bronchial epitbelium. Correspondence: S. Montef011 Dept of lmmWJOphannacology Medicine 1, Level D, Centre Block Southampton General Hospital Tremona Road The ~!-associated integrin subunit a2 was immunolocalized to all or the epithelial inten:eUular spaces, whilst a6 and JW were strongly evident at the basal cell layer basement membrane junction. The al and aS integrin subunits were not detected anywhere in the epithelium. Southampton S09 4XY UK

The Effect of Fiber Breakage on Transient Stress Distribution in a Single-Lap Joint Composite Material
In the present study, the transient stress distribution caused by a break in the fibers of an adhesive bonding is investigated. Transient stress is a dynamic response of the system to any discontinuity in the fibers from detachment time till their equilibrium state (or steady state). To derive the governing dynamic equilibrium equations shear lag model is used. Here, it is assumed that the tens...
متن کاملUsing the Finite Element Analysis Method to Study the 3-point Bending Test for the Characterization of the Adherence
An elastic finite element analysis was conducted to evaluate the stress distribution in the initiation zone of the adhesive rupture during the 3-point bending test. This test is used to measure the adherence between a polyepoxy adhesive and aluminum alloy with different surface treatments. The purpose is to compare, in the high stress concentration areas, the stress fields calculated using fini...
متن کاملViscoelastic analysis of stress distribution in balanced and unbalanced adhesively bonded single-lap joints with functionally graded adherends under the Reddy model
In this study, shear and peel stress distributions in the viscoelastic adhesive layer of a single-lap joint (SLJ) with functionally graded (FG) adherends are investigated. The study focuses on the effect of different adherend profiles and material composition on the time-dependent stress concentration/distribution in balanced and unbalanced SLJs. For this purpose, the Reddy model is applied to ...
متن کاملA review on stress distribution, strength and failure of bolted composite joints
In this study, analytical models considering different material and geometry for both single and double-lap bolted joints were reviewed for better understand how to select the proper model for a particular application. The survey indicades that the analytic models selected for the adhesively single or double bolted lap joints, as well as T, scarf, and stepped joints, with linear material pr...

Provide a healthy diet is one of the major health challenges in the world to maintain health and nutritional status of populations. In this reason, new control strategies such as probiotics have been applied as prophylactic and therapeutic instead of antibiotics. In the same line, probiotics have antagonistic effects to various microorganisms proposed in several mechanisms including improvement...
متن کاملApplications of higher order shear deformation theories on stress distribution in a five layer sandwich plate
In this paper, layerwise theory (LT) along with the first, second and third-order shear deformation theories (FSDT, SSDT and TSDT) are used to determine the stress distribution in a simply supported square sandwich plate subjected to a uniformly distributed load. Two functionally graded (FG) face sheets encapsulate an elastomeric core while two epoxy adhesive layers adhere the core to the face ...
