The T -matrix approach of quantum scattering theory is used here to place many long-wavelength equivalent-medium approximations for porous composites, polycrystals and cracked media on a common footing and to indicate their ...

Molecular-level condensed tannin analyses were conducted on a series of mangrove (Rhizophora mangle) leaves at various stages of decomposition in a tropical estuary. Total molecular tannin yields ranged from 0.5% ash-free ...

We analyzed 117 tissues from 77 different plant species for molecular tannin. Tannin was measured in 89 tissues (as high as 10.5 wt.% total tannin), including procyanidin (PC) tannin in 88 tissues, prodelphinidin (PD) ...

The major taphonomic processes that control insect preservation in carbonate rocks (limestones, travertines and nodules) are biological: insect size and wingspan, degree of decomposition, presence of microbial mats, predation ...

This paper describes the results of a wide-angle seismic profile, over 700km long, across the southern margin of the Tarim Basin. A crustal structure that best fits the observed data, that tests and verifies the earlier ...

The taxonomic position of the late form of the broad-fronted moose from the Middle Pleistocene of Eastern Siberia, Alces latifrons postremus Vangengeim et Flerov, 1965, is discussed. New finds of antler beams and a skull ...

Algae with a wide range of morphological characters were assigned to the genus Mizzia that was established without an estimate of the taxonomic importance of its characters. We considered the morphology of twigs on the ...

Variograms calculated from binary variables, such as from two lithologies, tend to show sinusoidal forms with decreasing amplitudes for increasing lag distances. This cyclicity is observed often when analyzing drill-hole ...

The Gangdese tectono-magmatic belt in the Tibetan continental collision zone can be divided, at least, three segments, i. e., western Gangdese (west to 85°E), middle Gangdese (85°E to 90°E) and eastern Gangdese (east to ...
