"Simple biography for younger children of the life of Henry VIII. Includes a timeline."--Publisher's description.

A Particle Image Velocimetry (PIV) experiment is designed and data collected with intention to validate Positron Emission Particle Tracking (PEPT) methods. The PIV data are collected in a narrow rectangular channel for flow Reynolds number near 20,000. The narrow channel and attendant pump, header tanks and flow instrumentation are portable and designed to allow identical tests in a Concord Microsystems MicroPET P4 pre-clinical PET scanner at the pre-clinical Imaging Suite at the UT Hospital. The PIV data are instantaneous velocity field data, allowing statistics on the flow turbulence to be collected in the Eulerian frame. The PEPT method measures activated particle trajectories in time, corresponding to a Lagrangian measurement. The relationship between the PIV data collected herein, and the anticipated PEPT data is explored to provide a path for validating the performance of the PEPT method for flow measurement. The utility of the PEPT method extends to opaque fluids and flow in complex and opaque flow boundaries. These flow conditions are impossible or technically difficult for optical PIV methods to address. The PEPT method also provides full 4 dimensional particle trajectory data, with temporal and spatial resolution competitive with the most advanced optical PIV methods.

This book explores what makes an animal a bird - how their characteristics are different from other groups of animals. It shows many examples of different types of birds in their natural environment.

For many people the word 'Somme' sums up the carnage and futility of the First World War. The failure of Allied forces to achieve their objectives at such a huge cost in human lives has resonated in military circles for the past 100 years. This book tells the story of the battle and its wider repercussions, and analyses its importance to the overall outcome of the First World War. The Somme investigates the build-up to the battle, why leaders thought the action was necessary and what they thought it would achieve. It looks at the forces involved, including the 'Pals' battalions, patriotic friends who fought, and more often than not died, together. Although not a straightforward timeline, the book outlines the actual course of the battle beginning on 1 July 1916 and the impact of the continuing slaughter on both sides. Quotes from those who took part offer a glimpse of what it must have been like to be there, and maps show how little was actually achieved in terms of a breakthrough. Poetry, art and music inspired by the Somme campaign bring the soldiers' harrowing experiences to life.

Designed to support the early science curriculum, How It's Made describes the technology behind everyday objects.
