A study of traditionnal throwing sticks and boomerang tuning
The first thing we could see about throwing sticks1 is their curved shapes. Though, even if their curved shape stabilise their flight by lowering their center of gravity, this seeming parameter isn't the only one to govern their trajectory. Others parameters, like their airfoil cross section, blade wideness, thickness, surface, and mass are also decisive. One another parameter less studied in d...
متن کاملDiet and trophic level of scalloped hammerhead shark (Sphyrna lewini) from the Gulf of California and Gulf of Tehuantepec, Mexico
We examined the diet and trophic level of Sphyrna lewini in the Gulf of California (GC) during 2001 and in the Gulf of Tehuantepec (GT) during 2005 using data from stomach content and stable isotope analysis of δ15N and δ13C. S. lewini diet was represented by pelagic and benthic prey species where the most important in weight was Scomber japonicus (27.70±4.54%) in GC, while in GT it was Auxis s...

متن کاملIdentifying recharge from tropical cyclonic storms, Baja California Sur, Mexico.
Groundwater in the Todos Santos watershed in southern Baja California, and throughout the peninsula south of latitude 28°N, has values of (δ18 O‰, δD‰) ranging between (-8.3, -57) and (-10.9, -78). Such negative values are uncharacteristic of the site latitude near the sea level. Altitude effects do not explain the isotope data. Tropical depressions originating along the Pacific coast of North ...
