Effect of submarine groundwater discharge on bacterial indicators and swimmer health at Avalon Beach, CA, USA.

Use of fecal indicator bacteria (FIB) for monitoring beach water quality is based on their co-occurrence with human pathogens, a relationship that can be dramatically altered by fate and transport processes after leaving the human intestine. We conducted a prospective cohort study at Avalon Beach, California (USA), where the indicator relationship is potentially affected by the discharge of sew...

Chemical weathering indices applied to weathering profiles developed on heterogeneous felsic metamorphic parent rocks

Chemical weathering indices are commonly used for characterizing weathering profiles by incorporating bulk major element oxide chemishy inlo a single metric for each sample. Generally, on homogeneous parent rocks, weathering indices change systematically with depth. However, the weathering of heterogeneous metamorphic rocks confounds the relationship between weathering index and depth. In this ...

Catalan Traffic at the Beach

The ubiquitous Catalan numbers Cn = (2n n ) / (n + 1) occur as t (n,−n) in the following table showing the number of ways to reach the point (n,m) on a rectangular grid under certain traffic restrictions, indicated by arrows. m 1↑→ 3↑→ 6↑→ 9↑→ 12↑→ 12↑→ 12↓→ ↘ 2 1↑→ 2↑→ 3↑→ 3↑→ 3↓→ ↘ 12↓→↘ 1 1↑→ 1↑→ 1↓→ ↘ 3↓→↘ 3↓→↘ 12↓→↘ start here 1↑→gate ↘ 1↓→↘ 1↓→↘ 3↓→↘ 6↓→↘ 15↓→↘ −1 ≈ 1 →↘ 1↓→↘ 2↓→↘ 4↓→↘ 9↓...
