Community-based nursing is. the application of the nursing process in caring for indi-. viduals and families in communitysettings. The focus of. community-based nursing is illness-oriented care of indi-. viduals and families throughout their life cycle.
A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.
Water density is governed by temperature and salinity; consequently, the thermocline coincides generally with the pycnocline, or layer in which density increases rapidly with depth. The middle layer of water in a lake or reservoir during the summer is also called a thermocline.
