“…With the spatial and temporal control of the microfluids, the optical properties can be varied, providing highly flexible, tunable, and reconfigurable optical systems. …”

“…This is because the results vary from no effect to large effect, and because of considerably varying quality of the documentation. …”

“…Yet surprisingly little is known about the economic costs that these risk factors cause, both for health care and society more widely.This study pulls together the evidence about the economic burden that can be linked to unhealthy diets and low physical activity and explores- How definitions vary and why this matters- The complexity of estimating the economic burden and- How we can arrive at a better way to estimate the costs of an unhealthy diet and low physical activity, using diabetes as an exampleThe review finds that unhealthy diets and low physical activity predict higher health care expenditure, but estimates vary greatly. …”

“…It’s tough to remember all the minute details of packaging standards and conversions when you are a designer juggling varied projects…”
