Interstellar extinction curve variations towards the inner Milky Way: a challenge to observational cosmology
(2016)
We investigate interstellar extinction curve variations towards similar to 4 deg(2) of the inner Milky Way in VIJK(s) photometry from the OGLE-III (third phase of the Optical Gravitational Lensing Experiment) and VVV (VISTA ...
Context-dependent extinction of an appetitive operant conditioned response in infant rats
(John Wiley & Sons Inc, 2017-03)
The present study evaluated context-dependent learning under an operant conditioning procedure in infant rats. Preweanling rats were trained in context A during postnatal days (PDs) 16 and 17 to learn an appetitive operant ...
Use of lignin extracted from different plant sources as standards in the spectrophotometric acetyl bromide lignin method
(Amer Chemical Soc, 2011)
A nongravimetric acetyl bromide lignin (ABL) method was evaluated to quantify lignin concentration in a variety of plant materials. The traditional approach to lignin quantification required extraction of lignin with acidic ...
Do the Photometric Colors of Type II-P Supernovae Allow Accurate Determination of Host Galaxy Extinction?
(2009)
We present infrared photometry of supernova (SN) 1999em, plus optical photometry, infrared photometry, and optical spectroscopy of SN 2003hn. Both objects were Type II-P SNe. The V − [RIJHK] color curves of these SNe evolved ...
Biotic recovery after the end-Triassic extinction event: Evidence from marine bivalves of the Neuquén Basin, Argentina
(Elsevier Science, 2017-12)
We analyze the Late Triassic extinction and Early Jurassic recovery of bivalve faunas within marine environments in the Atuel River area of the Neuquén Basin, Argentina. Data were collected from a hundred samples with ...
Social wasp-flower visiting guild interactions in less structurally complex habitats are more susceptible to local extinction
(Univ Estadual Feira Santana, 2013-09-01)
Several studies have shown that habitat complexity is an important factor for the dynamic and stability of interacting species. However, it is not known how the habitat complexity may affect the tolerance of wasp-flower ...
