Rift basins developed extensively across Sundaland, the continental core of Southeast Asia, since the Eocene. Beginning in the early Miocene, basins in southern Sundaland experienced widespread synchronous compression (inversion) and marine inundation, despite a large drop in long-term global sea level. The mechanism for this large-scale synchronous regional sea level rise, basin inversion, and...

distribution and mobility of nine mineral elements (k, ca, na, mg, fe, zn, cu, se, and cr) in cultured gentiana rigescens and its root zone soil were determined by atomic absorption spectroscopy. g. rigescens materials were planted under tea and white papaya trees in yun county and yongde of lincang area in yunnan province of china. the results showed that g. rigescens and its soil were high in...

Several descriptions of basically one transformation technique, viz. accumulation, are compared. Their basis, viz. the associativity and the existence of a neutral element inherent in a monoid, is identiied.

Snow accumulation in remote regions such as Greenland and Antarctica is a key factor for estimating Earth’s ice mass balance. In situ data are sparse, hence it is useful to derive snow accumulation from remote sensing observations, such as from microwave thermal emission and from radar brightness. These data are usually interpreted using electromagnetic models in which volume scattering is the ...

The phenotype of articular chondrocytes is dependent on the cytoskeleton, specifically the actin microfilament architecture. Articular chondrocytes in monolayer culture undergo dedifferentiation and assume a fibroblastic phenotype. This process can be reversed by altering the actin cytoskeleton by treatment with cytochalasin. Whereas dedifferentiation has been studied on chondrocytes isolated f...

Single-photon avalanche diodes (SPADs) are primary devices in photon counting systems used in quantum cryptography, time resolved spectroscopy and photon counting optical communication. SPADs convert each photo-generated electron hole pair to a measurable current via an avalanche of impact ionizations. In this paper, a stochastically self-regulating avalanche model for passively quenched SPADs ...

This paper deals with the origin of Pretare clastic deposit (PRA), which crops out along Morricone fluvial valley in Central Apennines Italy. With aim deciphering genesis PRA deposit, geological s.l. and geomorphological analyses were carried allowing for interpretation as a rock avalanche. Furthermore, cross sections constrained by well-log field survey data, together stratigraphic, sedimentol...

Relative to recreationists, avalanche professionals in Canada have a high success rate for managing avalanche hazard and making sound decisions in avalanche terrain. This success invites the question: What can be learned from these successes relative to avalanche education, decision support and accident prevention for backcountry recreationists? I surveyed Canadian avalanche professionals using...

this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...

The present paper deals with the force experienced by a wall overflowed by a granular avalanche. First, we briefly report laboratory tests on dry granular avalanches overflowing a wall down a rough channel. In the first step, the thickness and velocity of the control flows without a wall are measured. In the second step, a wall is mounted to obstruct the flow and the normal force experienced by...
