From Bipolar to Elliptical: Simulating the Morphological Evolution of Planetary Nebulae
From Bipolar Elliptical: Simulating Morphological Evolution Planetary Nebulae
2011/9/27
The majority of Proto-planetary nebulae (PPN) are observed to have bipolar morphologies. The majority of mature PN are observed to have elliptical shapes. In this paper we address the evolution of PPN...
The systematics of Holarctic bosminids and a revision that reconciles molecular and morphological evolution
Holarctic bosminidae a revision reconciles molecular morphological evolution
2014/5/26
Bosminids are ubiquitous and abundant crustacean herbivores in freshwater ecosystems. They are among the best preserved zooplankters in limnological sediments, making them ideal paleolimnological indi...
Particle Morphological Evolution During the Conversion of I/S to Illite in Lower Cretaceous Shales from Sergipe-Alagoas Basin, Brazil
Illite Illite/smectite Morphology Shale TEM XRD
2011/12/1
Abstract: The illitic end of mixed-layer illite-smectite series (I/S) in shales from Lower Cretaceous Barra de Itiúba Formation, Sergipe-Alagoas basin, was examined with X-ray powder diffraction (XRD)...
