Ever decreasing water resources and climate change have driven the increasing use of groundwater causing land subsidence in many countries. Geodetic sensors such as InSAR, GPS leveling can detect surface deformation but cannot measure subsurface deformation. A single-well, single-depth extensometer be used to deformation, it delineate depths major compaction provide insight about mechanism thro...

The anisotropic material behaviour of a recrystallized AA2198 Al-Cu-Li alloy in T3 and T8 conditions was assessed by proportional loading uniaxial-tension specimens rolling (L), transverse (T) diagonal (D) orientations. width longitudinal strains were measured to quantify plastic anisotropy. Notched-tension samples tested L T directions. showed weak anisotropy terms stress strain curves moderat...

Abstract Background Aortic stiffness independently predicts mayor adverse cardiovascular events and mortality in the general population. Cardiovascular magnetic resonance (CMR) permits assessment of a number parameters theoretically linked to aortic stiffness, such as distensibility (AD), pulse wave velocity (PWV) proximal aorta longitudinal strain. However, no previous study validates these de...

It has been suggested that in systemic sclerosis (SSc) the primary fault is in the microcirculation.' If this were so, then topical glyceryl trinitrate (GTN) might favourably influence skin blood flow and elasticity in areas of sclerodermatous skin change. Ten patients (three men, seven women; median age 48 years, range 24-70) fulfilling the American Rheumatism Association criteria for SSc2 wer...

PURPOSE To establish corneal cross-linking (CXL) with riboflavin and UV-A in in the mouse cornea in vivo and to develop tools to measure the biomechanical changes observed. METHODS A total of 55 male C57BL/6 wild-type mice (aged 5 weeks) were divided into 14 groups. Standard CXL parameters were adapted to the anatomy of the mouse cornea, and riboflavin concentration (0.1%-0.5%) and fluence se...

BACKGROUND The mechanical interaction between blood vessels and medical devices can induce strains in these vessels. Measuring and understanding these strains is necessary to identify the causes of vascular complications. This study develops a method to measure the three-dimensional (3D) distribution of strain using tomographic particle image velocimetry (Tomo-PIV) and compares the measurement ...

Low, intermediate and high strain rate tensile experiments are carried out on flat smooth, notched and central-hole tensile specimens extracted from advanced high strength steel sheets. A split Hopkinson pressure bar testing system is used in conjunction with a load inversion device to perform the high strain rate tension experiments. Selected surface strains, as well as local displacements, ar...

Because standard femoral supracondylar nails have certain disadvantages, they are often replaced by traditional femoral or tibial locked nails. The purpose of this study was to make a biomechanical comparison between both types of traditional locked nails to determine which technique was more suitable for treating unstable femoral supracondylar fractures. Fourteen left Sawbones femurs (Pacific ...
