This study identifies early, postmetamorphic soft-shell clams, Mya arenaria, as the life-history stage most
susceptible to effects of blooms of paralytic shellfish poisoning (PSP) toxin–producing Ale...

2010/3/9
Over the past several decades, galaxy formation theory has met with significant successes. In order to test current theories thoroughly we require predictions for as yet unprobed regimes. To this end,...
Cosmic star formation history revealed by the AKARI, & Spatially-resolved spectroscopy of an E+A (Post-starburst) system
evolution galaxies:starburst
2010/3/8
We reveal cosmic star-formation history obscured by dust using deep infrared observation with the AKARI. A continuous filter coverage in the mid-IR wavelength (2.4, 3.2, 4.1, 7, 9, 11, 15, 18, and 24u...

Flood history the karst environment of Castellana-Grotte
2009/12/10
Karst environments are characterized by peculiar hydrologic features, and in particular by a very limited, if not absent, surface hydrography. Water tends to infiltrate rapidly underground through the...
Observation of surface features on an active landslide, and implications for understanding its history of movement
surface features an active landslide history of movement
2009/12/10
Surface features are produced as a result of internal deformation of active landslides, and are continuously created and destroyed by the movement. Observation of their presence and distribution, and ...
