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.
One result of an increased greenhouse effect on Earth may be increased number of severe storms. Burning fossil fuels increases the greenhouse effect on Earth because of the release of CO2. Without naturally occurring greenhouse effect, Earth would be too cold to have liquid oceans. weak greenhouse effects operates on Mars.
