Pattern-distortion technique: using liquid-lens magnification to extract volumes of individual droplets or bubbles within evaporating two-dimensional arrays
We present an experimental "Pattern Distortion" technique which connects the shape of a liquid lens to its magnification. We demonstrate how to optimise the technique for arbitrary droplet sizes and optical configurations, and demonstrate its widespread utility in three distinct situations. Firstly we consider multiple sessile droplets. Although ubiquitous in nature, understanding of their complex interactions is limited, partly due to experimental limitations in determining individual droplet volumes for arbitrary configurations. We use the Pattern Distortion technique to overcome these limitations and find excellent agreement between our experimental data and three recent theoretical models. Secondly, we show how our technique can be used to inform the design of liquid lenses and thirdly we extend the method to composite droplets systems, using it to extract the size of an air bubble trapped inside a liquid droplet

Negative pressure therapy is effective to manage a variety of wounds in infants and children
Negative pressure wound therapy in the management of neonates with complex gastroschisis
Negative pressure wound therapy (NPWT) is an accepted form of treatment in managing complex wounds in adults and children. It is not as widely used in the neonatal population due to limited clinical experience. We describe the application of the RENASYS™ system (Smith and Nephew, UK) in delivering NPWT to four neonates with complex gastroschisis, all of whom achieved successful outcomes
