Movement patterns in free water play after swimming lessons with flotation aids [PDF]
, 2012 © 2012 Human Kinetics, Inc.The aim of this study was to investigate the movement patterns of children during free play in a swimming school setting. It was hypothesized that children being taught using flotation vests would be less likely to surface dive,

The kinetics of fast flotation using the reflux flotation cell
This paper examines the kinetics of Fast Flotation of very fine, hydrophobic particles using a rectangular-sectioned downcomer in the Reflux Flotation Cell (RFC). Three separate downcomers of equal height and breadth, but different channel widths of 2, 4.

The effect of energy input on flotation kinetics
, 2018 SYNOPSIS Energy/power input in a flotation cell is an important parameter which, if optimised, can increase the flotation rate. The optimum energy/power input within a flotation cell is still a matter of conjecture and there is a need for a better ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).
