Void Dynamics [PDF]

open access: yesProceedings of the International Astronomical Union, 2014
AbstractCosmic voids are becoming key players in testing the physics of our Universe. Here we concentrate on the abundances and the dynamics of voids as these are among the best candidates to provide information on cosmological parameters. Cai, Padilla & Li (2014) use the abundance of voids to tell apart Hu & Sawicki f(R) models from General ...

Micro-computed tomography analysis of void volume in sealer layer placed using Vibrospiral novel instrument: an in vitro study [PDF]

open access: yesFrontiers in Dental Medicine
AimEndodontic sealers form an intermediary layer between the solid canal filling material, like gutta-percha, and the dentinal wall to fill the voids and porosities between them and establish a fluid-impervious seal, which is essential to prevent ...

Spatial Behavior of Solutions in Linear Thermoelasticity with Voids and Three Delay Times

open access: yesMathematics, 2023
This brief contribution aims to complement a study of well-posedness started by the same authors in 2020, showing—for that same mathematical model—the existence of a domain of influence of external data.

Quality Control Approach for the Detection of Internal Lower Density Areas in Composite Disks in Industrial Conditions Based on a Combination of NDT Techniques

open access: yesSensors, 2021
Voids in polymer matrix composites are one of the most common manufacturing defects, which may influence the mechanical properties and structural behavior of the final parts made of composites by various manufacturing methods.

Study on the Laboratory Mixing and Compaction Methodology of Emulsified Asphalt Cold Recycled Mixture

open access: yesFrontiers in Materials, 2020
Emulsified asphalt cold recycled mixture is commonly used in the upper base course of expressway reconstruction asphalt pavement. When the following layer is paved with hot-mix asphalt (HMA) mixture, the aging asphalt in the recycled material is ...

An overview of the urbanism style during the Italian era in Benghazi downtown, Libya

open access: yesJournal of Architecture and Urbanism, 2022
Axiomatically, urban fabric is the result of civilizations and ideas overlapping rather than being bound to a single civilization or culture. Benghazi, like many other Arab cities in developing countries, retains relics of its past in the old city core.

The Effect of Rhenium Content on Microstructural Changes and Irradiated Hardening in W-Re Alloy under High-Dose Ion Irradiation

open access: yesNanomaterials, 2023
An amount of 100 dpa Si2+ irradiation was used to study the effect of transmutation rhenium content on irradiated microscopic defects and hardening in W-xRe (x = 0, 1, 3, 5 and 10 wt.%) alloys at 550 °C.

Effect of Strengthening Methods on the Defect Evolution under Irradiations Investigated with Rate Theory Simulations

open access: yesMetals, 2019
Under irradiations, mechanical performance of nuclear alloys would degrade due to irradiation induced defects. Different strengthening methods can play a different role in the evolution of the defects.
