Abstract We should recognize that both experimentalists and theoreticians have shared until recently the comfortable dream-world of two-dimensionality and that the vast majority of the reported measurements on flow around cylinders contained an unknown dose of bias and distortion via two-dimensional interpretations.

Aspect-ratio-controlled synthesis of high-aspect-ratio gold nanorods in high-yield
Current Applied Physics, 2009Abstract We describe a modified seed-mediated synthesis of high-aspect-ratio gold nanorods controlling the aspect ratio with variation of pH in the growth solution. By adding various amounts of sodium hydroxide, pH in the growth solution was controlled from 1.29 to 7.06 in the presence of nitrate anions.

Transition to large aspect ratio convection
Physical Review E, 1994We describe experiments with aspect ratio \ensuremath{\Gamma} in the range 44\ensuremath{\le}\ensuremath{\Gamma}\ensuremath{\le}90 that characterize the transition from moderate- to large-\ensuremath{\Gamma} convection. Up to \ensuremath{\Gamma}=60, the flows are steady until well above the convective onset.

Journal of Engineering for Power, 1964
Four different axial, impulse turbines with extremely low aspect ratios (between 0.07 and 0.70) were tested over wide ranges of pressure and speed ratios. The influence on mass rate of flow and efficiency of Reynolds number and axial distance between stator and rotor is given.

Some aspects of sex ratio studies
Acta Paediatrica, 2016This issue of Acta Paediatrica contains a paper by Grech and Borg that explores the seasonality of sex ratios at birth and the effect of the famous volcanic eruption in April 2010, which caused widespread disruption to air traffic all over Europe. The authors report that a slight decline in male births was noted after the eruption and conclude that ...
