Acidic deposition: decline in mobilization of toxic aluminium.

abstract：:The annual cycle in the Earth's surface temperature is extremely large-comparable in magnitude to the glacial-interglacial cycles over most of the planet. Trends in the phase and the amplitude of the annual cycle have been observed, but the causes and significance of these changes remain poorly understood-in part beca...

Each retinal ganglion cell type tessellates the retina in a regular mosaic, so that every point in visual space is processed for visual primitives such as contrast and motion. This information flows to tw...
