Local Voids as the Origin of Large-angle Cosmic Microwave Background Anomalies: The Effect of a Cosmological Constant [PDF]

open access: yes, 2006
We explore the large angular scale temperature anisotropies in the cosmic microwave background (CMB) due to homogeneous local dust-filled voids in a flat Friedmann-Robertson-Walker universe with a cosmological constant.

Banana Fiber Extraction and Surface Characterization of Hybrid Banana Reinforced Composite

open access: yesJournal of Natural Fibers, 2022
For many engineering applications, especially in case of automobiles, natural fibers are a better replacement for artificially made fibers when it is reinforced as polymer composite materials.

Distribution and Evolution Law of Void Fraction in the Goaf of Longwall Mining in a Coal Mine: Calculation Method and Numerical Simulation Verification

open access: yesApplied Sciences, 2023
Many voids are produced in the mining process of ore-bearing strata. To explore the development law of voids after mining coal-bearing strata, a theoretical model was established to derive the overall distribution and shape of voids in the goaf.

Three-dimensional molecular dynamics simulations of void coalescence during dynamic fracture of ductile metals

open access: yes, 2005
Void coalescence and interaction in dynamic fracture of ductile metals have been investigated using three-dimensional strain-controlled multi-million atom molecular dynamics simulations of copper. The correlated growth of two voids during the coalescence

Effects of a magnetic field and initial stress on reflection of SV-waves at a free surface with voids under gravity

open access: yesJournal of the Mechanical Behavior of Materials, 2018
The present study deals with the reflection of SV-waves at a free surface in the presence of magnetic field, initial stress, voids and gravity. When an SV-wave incident on the free surface of an elastic half space, two damped P-waves and an SV-wave are ...

Analysis of Failure Mode of Reinforced Embankments Overlying Voids Based on Discrete Method

open access: yesApplied Sciences, 2023
The mode of the reinforced embankment overlying voids was generated based on discrete element software. By changing the vertical distance H and the horizontal distance L, the influence of the void position on the bearing capacity characteristics ...

Automated Detection of Voids in Redshift Surveys

open access: yes, 1996
We present a new void search algorithm for automated detection of voids in three-dimensional redshift surveys. Based on a model in which the main features of the LSS of the Universe are voids and walls, we classify the galaxies into wall galaxies and ...

Partial discharges in spheroidal voids. Void orientation [PDF]

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 1997
Partial discharge transients can be described in terms of the charge induced on the detecting electrode. The influence of the void parameters upon the induced charge is examined and discussed for spheroidal voids. It is shown that a quantitative interpretation of the induced charge requires a knowledge not only of the void location, geometry and ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
