A Study of Active Galactic Nuclei in Low Surface Brightness Galaxies with Sloan Digital Sky Survey Spectroscopy

open access: yes, 2008
Active galactic nuclei (AGN) in low surface brightness galaxies (LSBGs) have received little attention in previous studies. In this paper, we present detailed spectral analysis of 194 LSBGs from the Impey et al.

Failure pressures of composite cylinders with a plastic liner

open access: yesJournal of Reinforced Plastics and Composites, 2011
The present experimental study deals with the temperature and the stacking sequence effects on the response of the composite cylinders under the internal pressure. GRP composite cylinders were manufactured by using E-glass fibers and epoxy resin and tested for the close-ended condition.

Spectral Properties of Galaxies in Void Regions

open access: yes, 2015
We present a study of spectral properties of galaxies in underdense large-scale structures, voids. Our void galaxy sample (75,939 galaxies) is selected from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) with $\rm z < 0.107$. We find that there

Migration behavior of landfill leachate contaminants through alternative composite liners

open access: yesScience of The Total Environment, 2011
Four identical pilot-scale landfill reactors with different alternative composite liners were simultaneously operated for a period of about 540 days to investigate and to simulate the migration behaviors of phenolic compounds (phenol, 2-CP, 2-MP, 3-MP, 4-MP, 2-NP, 4-NP, 2,4-DNP, 2,4-DCP, 2,6-DCP, 2,4,5-TCP, 2,4,6-TCP, 2,3,4,6-TeCP, PCP) and heavy ...
