Experimental and Numerical Research on Cylindrical Tubes under Outer Cylindrical Explosive Waves

open access: yesShock and Vibration, 2017
Cylindrical explosive loading has an important application in explosive working, researching on weapon damage, and explosive-driving load. This study uses experimental and numerical methods to study the response of long and thin tubes when subjected to ...

A comparison of two manual catching methods of broiler considering injuries and behavior

open access: yesPoultry Science, 2022
: The aim of this study was to compare the 2 manual catching methods in terms of injuries and behavior. Throughout 12 loadings on practical farms with the same standard, 1 container each was caught using the one-legged (1LCM) and 1 using the two-legged ...

Anisotropic shock response of columnar nanocrystalline Cu [PDF]

open access: yes, 2010
We perform molecular dynamics simulations to investigate the shock response of idealized hexagonal columnar nanocrystalline Cu, including plasticity, local shear, and spall damage during dynamic compression, release, and tension.

Cascade anchoring strategy for general mass production of high-loading single-atomic metal-nitrogen catalysts

open access: yesNature Communications, 2019
Although single-atomically dispersed metal-Nx on carbon support (M-NC) has great potential in heterogeneous catalysis, the scalable synthesis of such single-atom catalysts (SACs) with high-loading metal-Nx is greatly challenging since the loading and ...

Left-right loading dependence of shock response of (111)//(112) Cu bicrystals: Deformation and spallation [PDF]

open access: yes, 2012
We investigate with molecular dynamics the dynamic response of Cu bicrystals with a special asymmetric grain boundary (GB), (111)//(112)〈110〉, and its dependence on the loading directions. Shock loading is applied along the GB normal either from the left

Modeled nitrogen loading to Narragansett Bay: 1850 to 2015 [PDF]

open access: yes, 2010
Nutrient loading to estuaries with heavily populated watersheds can have profound ecological consequences. In evaluating policy options for managing nitrogen (N), it is helpful to understand current and historic spatial loading patterns to the system. We

Effect of primary treatment and organic loading on methane emissions from horizontal subsurface flow constructed wetlands treating urban wastewater [PDF]

open access: yes, 2015
Methane is emitted in horizontal subsurface flow constructed wetlands (HSSF CWs) during wastewater treatment. The objective of this work was to determine the influence of primary treatment and organic loading rate on methane emissions from constructed ...

Stamina of a non-gasketed flange joint under combined internal pressure, axial and bending loading : an experimental study [PDF]

open access: yes, 2009
The performance of a bolted flange joint is characterized mainly by its 'strength' and 'sealing capability'. A number of numerical and experimental studies have been conducted to study these characteristics under internal pressure loading conditions alone.

Fracture Resistance of Zirconia Oral Implants In Vitro: A Systematic Review and Meta-Analysis [PDF]

open access: yes, 2020
Various protocols are available to preclinically assess the fracture resistance of zirconia oral implants. The objective of the present review was to determine the impact of different treatments (dynamic loading, hydrothermal aging) and implant features (
