Non-stick water

Stick-slip sliding of water drops on chemically heterogeneous surfaces.

We present a comprehensive study of water drops sliding down chemically heterogeneous surfaces formed by a periodic pattern of alternating hydrophobic and hydrophilic stripes. Drops are found to undergo a stick-slip motion whose average speed is an order of magnitude smaller than that measured on a homogeneous surface having the same static contact angle. This motion is the result of the period...

New international measuring stick for defining obesity in non-Europeans.

Body mass index (BMI) is a useful way of classifying the degree of excess weight in an individual. Defining BMI cut points at which adverse cardiovascular outcomes, diabetes mellitus, and other comorbidities are more likely to occur affords clinically relevant guidelines for patient care. Expert panels from both the National Institutes of Health and the World Health Organization1–3 have develop...

A Carrot-and-Stick Approach to Environmental Improvement: Marrying Agri-Environmental Payments and Water Quality Regulations

Agri-environmental programs, such as the Environmental Quality Incentives Program, provide payments to livestock and crop producers to generate broadly defined environmental benefits and to help them comply with federal water quality regulations, such as those that require manure nutrients generated on large animal feeding operations to be spread on cropland at no greater than agronomic rates. ...
