Estimation of uniaxial compressive and indirect tensile strengths of intact rock from Schmidt hammer rebound number

open access: yesJournal of the Mechanical Behavior of Materials, 2023
A number of destructive and non-destructive tests were conducted on rock samples collected from various zones in northern Iraq. So far, for Iraqi rocks, few studies have correlated Schmidt hammer rebound (R) with both unconfined compressive strength (UCS)

Statistical Equations to Estimate the In-situ Concrete Compressive Strength from Non-destructive Tests

open access: yesJournal of Engineering, 2018
The aim of this study is to propose reliable equations to estimate the in-situ concrete compressive strength from the non-destructive test. Three equations were proposed: the first equation considers the number of rebound hummer only, the second equation

Children grow and horses race: is the adiposity rebound a critical period for later obesity? [PDF]

open access: yes, 2004
BACKGROUND: The adiposity rebound is the second rise in body mass index that occurs between 3 and 7 years. An early age at adiposity rebound is known to be a risk factor for later obesity.

Experimental Study on the Compressive Strength of Big Mobility Concrete with Nondestructive Testing Method

open access: yesAdvances in Materials Science and Engineering, 2012
An experimental study of C20, C25, C30, C40, and C50 big mobility concrete cubes that came from laboratory and construction site was completed. Nondestructive testing (NDT) was carried out using impact rebound hammer (IRH) techniques to establish a ...

Compressive Strength Prediction Model of High Strength Concrete by Destructive and Nondestructive Technique [PDF]

open access: yesE3S Web of Conferences
Concrete’s compressive strength can be tested in a laboratory before construction begins. Since concrete is a natural material and cannot be destroyed, it is not possible to determine its compressive strength through destructive testing.

Comparatively Study of Non-Destructive test with different methods in various curing days [PDF]

open access: yesE3S Web of Conferences
In non-destructive testing, materials, components, or assemblies are inspected, tested, or evaluated without being destroyed. In nondestructive testing, materials, components, and assemblies are evaluated for quality and integrity without damaging them ...

Virological and immunological outcome of treatment interruption in HIV-1-infected subjects vaccinated with MVA-B. [PDF]

open access: yesPLoS ONE, 2017
The most relevant endpoint in therapeutic HIV vaccination is the assessment of time to viral rebound or duration of sustained control of low-level viremia upon cART treatment cessation.

Maximum Spreading and Rebound of a Droplet Impacting onto a Spherical Surface at Low Weber Numbers [PDF]

open access: yesLangmuir, 2018
The spreading and rebound patterns of low-viscous droplets upon impacting spherical solid surfaces are investigated numerically. The studied cases consider a droplet impinging onto hydrophobic and superhydrophobic surfaces with various parameters varied throughout the study, and their effects on the postimpingement behavior are discussed.

Not all missed doses are the same: sustained NNRTI treatment interruptions predict HIV rebound at low-to-moderate adherence levels. [PDF]

open access: yesPLoS ONE, 2008
While the relationship between average adherence to HIV potent antiretroviral therapy is well defined, the relationship between patterns of adherence within adherence strata has not been investigated. We examined medication event monitoring system (MEMS)
