Extinction Curves of Lensing Galaxies out to z=1 [PDF]

Astrophys.J.Suppl.166:443-469,2006, 2006
We present a survey of the extinction properties of ten lensing galaxies, in the redshift range z = 0.04 - 1.01, using multiply lensed quasars imaged with the ESO VLT in the optical and near infrared. The multiple images act as 'standard light sources' shining through different parts of the lensing galaxy, allowing for extinction studies by comparison ...

Climate change and the selective signature of the Late Ordovician mass extinction [PDF]

, 2012
Selectivity patterns provide insights into the causes of ancient extinction events. The Late Ordovician mass extinction was related to Gondwanan glaciation; however, it is still unclear whether elevated extinction rates were attributable to record ...

Dust distribution in L1217/L1219: Nice vs. Nicer [PDF]

Serbian Astronomical Journal, 2004
The dust in molecular clouds reliably traces the molecular gas within. We used this assumption to get an estimate of the dense cores size and mass in L1217/L1219 by deriving the total optical extinction, and therefore, the total column density.

Methanolic extract of Morinda citrifolia L. (noni) unripe fruit attenuates ethanol-induced conditioned place preferences in mice

Frontiers in Pharmacology, 2016
Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on

The Rise of the Anthroposphere since 50,000 Years: An Ecological Replacement of Megaherbivores by Humans in Terrestrial Ecosystems?

Frontiers in Ecology and Evolution, 2018
Megaherbivores fulfilled a number of important ecological functions in terrestrial ecosystems and behaved as ecological engineers since 300 million years until around 12,000 years ago. These essential ecological functions include opening vegetation cover,
