A simple model based on canopy structure is developed to explain the vertical distribution of clouds of droplets in a crop canopy. An attenuation coefficient derived from experiments in cotton was insensitive to droplet size in the range 40--200 ~zm and to the microclimate.

β¦ Synopsis
Based on a model of aerial dispersion of spray clouds released from aircraft, criteria are given for choosing droplet sizes and flying heights in practical crop-spraying situations. There are advantages in using sprays composed of small droplets; micrometeorological measurements over cotton suggest that maximum droplet diameters should be about 60 pm.

## Abstract Hydroxylapatite (HA) is one of the most important materials for human hard tissue implants. Until now, HA coatings are widely deposited on implants using atmospheric plasma spraying (APS). Due to the decomposition of HA and formation of amorphous phase during spraying, the crystallinity
