Using a Spoon to Clean the Air

A flipped spoon and chin prompt to increase mouth clean.

We treated the liquid refusal of a 15-month-old girl using 2 antecedent manipulations: flipped spoon and chin prompt. Use of the chin prompt in the absence of the flipped spoon failed to produce increases in mouth clean (a product measure of swallowing). By contrast, modest increases in mouth clean resulted from the implementation of the flipped spoon alone. The greatest increases in mouth clea...

Why Is Clean Air Clean?

Air exhibiting very low concentrations of light-scattering aerosol particles is occasionally observed even in industrialized regions. Evidence is presented that this very clean air results from highly efficient removal of aerosol particles coupled to the removal of water in precipitation.

Clean air in the Anthropocene.

In atmospheric chemistry, interactions between air pollution, the biosphere and human health, often through reaction mixtures from both natural and anthropogenic sources, are of growing interest. Massive pollution emissions in the Anthropocene have transformed atmospheric composition to the extent that biogeochemical cycles, air quality and climate have changed globally and partly profoundly. I...

Clean air is the key to clean lungs: Secondhand smoke is injurious to health

Both developed and less developed countries are becoming increasingly urbanized. The earlier industrialized countries have developed more infrastructure to support the building of healthy housing, in neighborhoods that are strongly linked to municipal and global health initiatives, but to some degree housing and neighborhood issues vary only in degree between the developing and developed worlds...
