Sedimentological Analysis of Sands
This paper presents a practical sequence to study sand grains at the macroscopical scale. The approach consists of two mains phases, the recognition of the grains and the assessment of some of its characteristics. The method is validated on the dimensional features by comparison with a sieving procedure through the analysis of eight large sand samples of different locations.
متن کاملFeathered dinosaurs, flying dinosaurs, crown dinosaurs, and the name “Aves”
The taxon name “Aves” is currently used for several different clades, a situation that violates the fundamental nomenclatural principle that, to minimize ambiguity, each taxon name should refer to a single taxon. To clarify this situation, we explore some general issues concerning the properties of the three classes of phylogenetic definitions, including: how names can be tied to clades through...

How have anoles evolved such diverse morphologies? This is an exciting time in anole biology because recently the genome of the green anole, Anolis carolinensis, was completely sequenced (http://www.broad.mit. edu/models/anole/). The completion of an anole genome opened a new avenue of research into the genetic changes that accompany adaptive radiation. Researchers would like to know how many, ...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولSedimentological study of the Szőreg-1 reservoir (Algyő Field, Hungary): a combination of traditional and 3D sedimentological approaches
The paper presents a 3D sedimentological characterization of a delta plain reservoir. The analysis started with detailed core description studies focusing on the genetic interpretations of the sedimentary structures and multivariate statistical analyses (including Q-mode cluster and R-mode factor analysis), of the sporadic grain-size distributions. These results made the depositional processes ...
