Modification of the biological intercept model to account for ontogenetic effects in laboratory-reared delta smelt (Hypomesus transpacificus)* [PDF]
, 2007 We investigated age, growth, and ontogenetic effects on the proportionality of otolith size to fish size in laboratory-reared delta smelt (Hypomesus transpacificus) from the San Francisco Bay estuary.

The Hatching of a Peripatus Egg [PDF]
Nature, 1893 In NATURE, vol. xliv, p. 468, I briefly described some eggs of the larger Victorian Peripatus, which were laid by specimens kept alive by me in the winter (Australian) of 1891. At that time, following previous authority, I identified the species which laid the eggs as P. leuckartii. It appears now, however, that the real P.

Egg quality of an Asian catfish of the Mekong river (Pangasius hypophthalmus) during the process of maturation induced by hCG injections [PDF]
, 1998 In captive Pangasius hypophthalmus, oocyte maturation and ovulation are induced by hormonal injection following a given protocol: preparatory injections (500 VI.kg-) and decisive injection (2000 VI.kg-).

Advanced Engineering Materials, EarlyView.Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...
