We report of the distribution of major and trace element concentrations in epipelagic zooplankton collected in the Northern Gulf of California in August 2003. The Bray–Curtis index defined three element assemblages in ...

Hollow CeO2 microspheres, having 3D architectures on their surface, were prepared by a microwave-assisted coprecipitation method. By this method, ceric ammonium nitrate was diluted in formic acid. The application of microwave ...

The morphology and ecology of paralarvae (PL) through to the juvenile stages are unknown in most cephalopod species in spite of their importance as indicators of biodiversity, of adult spawning grounds, and as key basis ...

The number, size, and shape of lakes are key determinants of the ecological functionality of a lake district. The lake area scaling relationships with lake number and volume enable upscaling biogeochemical processes and ...

Stone materials, despite their great stability as construction materials, are not free from deterioration caused by nature, an effect that has been intensified by urban and industrial developments. Laser-induced breakdown ...
