This study demonstrated a relationship between care given according to Watson's Caring model and increased quality of life of the patients with hypertension. Further, in those patients for whom the caring model was practised, there was a relationship between the Caring model and a decrease in patient's blood pressure.
The greenhouse effect is a warming of Earthâs surface and the air above it. It is caused by gases in the air that trap energy from the sun. These heat-trapping gases are called greenhouse gases. The most common greenhouse gases are water vapor, carbon dioxide, and methane.
Greenhouse effect - Bodies other than Earth. 1  In the Solar System, there are also greenhouse effects on Mars, Venus, and Titan. 2  The greenhouse effect on Venus is particularly large because its dense atmosphere consists mainly of carbon dioxide. 3  The greenhouse effect on Mars is small as its atmosphere is tenuous.
