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 ...

Marine Eemian deposits along the Pyoza river and its tributary Varchuska, Arkhangelsk region, constitute successions of muddy and sandy facies with rich macrobenthic fauna dominated by bivalves and barnacles. Taphonomic ...

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 ...

Common variogram models, such as spherical or exponential functions, increase monotonically with increasing lag distance. On the other hand, a hole-effect variogram typically exhibits sinusoidal waves that form peaks and ...

The unconfined compression load-displacement curves for rock samples were described. A series of uniaxial compression tests was performed to implement and compare two different methods of deformation measurements. Stress-strain ...

Regularities in change of electrical properties of rocks observed laterally and with depth above the probable oil-and-gas deposits are examined. A technique for preliminary estimation of oil-and-gas content of the sedimentary ...
