Zambezi two largest left-hand tributaries of the Zambezi. The Kafue joins the main river in a quiet deep stream about wide. From this point the northward bend of the Zambezi is checked and the stream continues due east. At the confluence of the Luangwa (15°37' S) it enters Mozambique. The middle Zambezi ends where the river enters Lake Cahora Bassa (also spelled Cabora Bassa). Formerly the site of dangerous rapids known as Kebrabassa, the lake was created in 1974 by the construction of the Cahora Bassa Dam. The lower Zambezi's 650 km from Cahora Bassa to the Indian Ocean is navigable,
Body composition density. The technique then estimates the percentage of body fat and lean body mass (LBM) through empirically derived equations similar to those used with underwater weighing (for the density of fat and fat free mass). Another method is bioelectrical impedance analysis (BIA), which uses the resistance of electrical flow through the body to estimate body fat. Unfortunately, BIA is highly sensitive to hydration status and water intake. Drinking water dilutes the electrolytes in the body making it less conductive as does increasing body fat. The Body Volume Indicator (BVI) is a technique used for measuring body shape. Initially, BVI technology
