In this book it's a combination of Russians and Japanese. While these "villains" might feel stale and overdone, Humphrey (who is actually a British author), overcomes these potential pitfalls with his fantastic writing. For lovers of political intrigue, action, adrenaline and drama, you must pick up a copy of Ice Islands by Humphrey Hawksley.

Spiral separators for the recovery of ultra-fine particles have a unique profile, pitch and features to ensure it performs efficiently. The flow on the spiral trough must be controlled to minimise turbulence that will entrain fine particles in the outer section of the trough. Keywords: Ultra-fine particles, spiral, design, recovery 1. Introduction

Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992). The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).

Even on broadcast, the cut to Humphrey seems slightly odd here; it feels like there was more to the scene.
