Osmolality of blood increases with dehydration and decreases with overhydration. In normal people, increased osmolarity in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma.
Marcus Terentius Varro Quotes. Marcus Terentius Varro (116-27 B.C.) was the greatest Roman scholar and an incredibly prolific writer. It is estimated that he wrote 74 separate works in 620 volumes on all aspects of contemporary learning. Varro was born at Reate in the Sabine country into a family of some means.
The leader of the Varangians was the semilegendary warrior Rurik, who led his people in 862 to the city of Novgorod on the Volkhov River. Whether Rurik took the city by force or was invited to rule there, he certainly invested the city. From Novgorod, Rurik's successor Oleg extended the power of the city southward. In 882, he gained control of Kiev, a Slavic city that had arisen along the Dnepr River around the 5th century.
