Asthma is an allergic airways disease (AAD) caused by dysregulated immune responses and characterized by eosinophilic inflammation, mucus hypersecretion, and airway hyperresponsiveness (AHR). NKT cells have been shown to contribute to AHR in some mouse models. Conversely, regulatory T cells (Tregs) control aberrant immune responses and maintain homeostasis. Recent evidence suggests that Strepto...

Soy wood adhesive bond strengths reported in different literature studies are difficult to compare because a variety of temperatures and other conditions have been used for the bonding and testing step. Some reports have indicated bond strengths are sensitive to bonding temperature, but the reason(s) for this has not been intensively investigated. Although these prior studies differ in other wa...

Manufacturing induced imperfections in composites lead to a reduction the performance of structure. In order carry out repairs only when they are really necessary, evaluation capabilities determine strength required. Two methods presented: finite element based and Peridynamic approach, respectively. The process is used evaluate stiffness reduction. This processes currently doesn't include progr...

The effect of ply thickness on the notch sensitivity and bearing properties carbon fibre reinforced polymer composites their hybrid laminates with steel foils were studied. Laminates thicknesses 0.3 mm 0.03 comprising CFRP manufactured characterized using tension, open hole tension double lap tests. A 25% substitution was found to load extensive plastic deformation in joint while maintaining hi...

STUDY DESIGN Pedicle screw strength or load to failure was biomechanically evaluated, and the geometric characteristics of pedicle screw instrumentation systems were compared. OBJECTIVES To compare the features of pedicle screw systems, and to demonstrate the failure point of the polyaxial pedicle screw head. SUMMARY OF BACKGROUND DATA Many pedicle screw instrumentation systems are currentl...

Abstract This study investigates the influence of local hybridization Thin and Thick-Ply CFRP laminates on open-hole bearing properties. The area weight unidirectional prepregs used is 40 gsm in case Thin-Ply layers 160 gsm layers. steel a 1.4310 stainless-steel foil with same layer thickness as prepregs. In hybrid area, 90 ∘ were locally replaced by stainless patches. metal content varies from...

This work investigates the high strain rate behavior of AP-PLY composites. The large representative volume elements and brittle nature this material necessitated use a bespoke split-Hopkinson bar apparatus. baseline laminates were subjected to tensile loading at rates 30 s −1 . Results compared with quasi-static data evaluate whether laminate architecture introduced any dependency. In addition,...

In this study, we determined the flexural properties and tensile shear strength of five-ply plywood panels produced with eucalyptus (Eucalyptus grandis), beech (Fagus orientalis), and hybrid poplar (Populus x euramericana) using urea-formaldehyde (UF), melamine-urea-formaldehyde (MUF) and phenol-formaldehyde (PF) adhesives. Flexural properties were tested on both parallel and perpendicular to g...

in this study, a simulation of tire–soil interaction model was considered with special view to two-dimensional (2-d) fem model of carcass. coefficients of mechanical behavior of silty-loam soil were accurately measured to obtain an effective simulation. the results of simulation which was implemented in matlab7, showed that the radial-ply tire had greater tractive efficiency than bias tire at t...

OBJECTIVE Viral load testing is used in the HIV programme of Chiradzulu, Malawi, to confirm the diagnosis of immunological failure to prevent unnecessary switching to second-line therapy. Our objective was to quantify the benefit of this strategy for management of treatment failure in a large decentralized HIV programme in Africa. METHODS Retrospective analysis of monitoring data from adults ...
