Patients selecting mechanical heart valve replacements are typically required to monitor their INR levels (international normalized ratio) to prevent risks of blood clotting, hemorrhage or stroke. To ease this process, home INR testing machines are now becoming more affordable and easy-to-use.
Archaeologists and historians don't know exactly how Egyptian civilization evolved. It is believed that humans started living along the Nile's banks starting in about 6,000 B.C.E. For the earliest inhabitants of the Nile Valley food was not easy to find.
The Egyptians lived along the River Nile, the fertile river in north eastern Africa. This river flows from the central part of Africa. The Nile's water flows north, until it empties into the Mediterranean Sea. At the northern most part of the Nile, the Nile forms a delta.he ancient Egyptians ate food that is not much different from what we eat today. Because the Nile River supplied them with a constant water source, the Egyptians were able to grow many different kinds of crops in their desert environment.
