The effect of transition regions between continental and oceanic structures on the propagation of L, waves from continental sources is examined. In particular, the attenuation due to variations in layer thickness in such transition regions is calculated and explained for a suite of simple models. The measured attenuation, due tq the geometry of the transition regions between the oceanic and con...

The equid family contains only one single extant genus, Equus, including seven living species grouped into horses on the hand and zebras asses other. In contrast, equine fossil record shows that an extraordinarily richer diversity existed in past provides multiple examples of a highly dynamic evolution punctuated by several waves explosive radiations extinctions, cross-continental migrations, l...

Abstract Big data are potentially useful for environmental management planning and actions that can be directed toward pollution control. China is using big approaches to help reduce its current levels of pollution. However, also needed better indicators, measurement technologies, reporting, adaptive enforcement. Based on continental-extent monitoring assessment programs in Europe the USA, we r...

Arc continent collision is one of the most fundamental tectonic processes for the formation of new land, and the preservation on land of fragments of oceanic lithosphere (ophiolites). However, the tectonic evolution of arc continent collision is commonly over-simplified in everything from introductory textbooks to complex tectonic models. Major unresolved issues include the response of the fore...

Chronically hemodialyzed (HD) patients frequently suffer from quantitative and even more often qualitative serum lipids disorders. Mostly they have increased triglycerides and VLDL-cholesterol, slightly increased or normal total and LDL-cholesterol and decreased HDL-cholesterol concentrations. The study compared lipid profile between two groups of chronic HD patients coming from regionally dist...

STOCK DEFINITION AND GEOGRAPHIC RANGE The northern Gulf of Mexico (i.e., U.S. Gulf of Mexico) continental shelf bottlenose dolphin stock inhabits waters from 20 to 200 m deep in the northern Gulf from the U.S.-Mexican border to the Florida Keys (Figure 1). Both “coastal” and “offshore” ecotypes of bottlenose dolphins occur in the Gulf of Mexico (Hersh and Duffield 1990; LeDuc and Curry 1998). T...

T study of the deep structure and evolution of passive continental margins is important for the understanding of rifting processes and the formation of associated sedimentary basins. Since the classical models of McKenzie (1978) and Wernicke (1985), understanding how passive continental margins form, that is to say mainly the way that continental lithosphere is thinned leading to subsidence, re...

The Crew ResourceSolver decision-support system employs advanced optimization modeling and solution techniques to solve complex, large-scale pilot staffing and training problems at Continental Airlines. The system determines optimal pilot transitions and efficiently allocates and schedules training resources. The results are improved staffing levels and substantial cost savings through reduced ...

There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C. We reassess this value in the light of more rece...
