The Bulgars, at least the Danubian Bulgars, had a well-developed clan and military administrative system of "inner" and "outer" tribes, [109] governed by the ruling clan. [110] They had many titles, and according to Steven Runciman the distinction between titles which represented offices and mere ornamental dignities was somewhat vague. [ 111 ]
The early Bulgars were a warlike people and war was part of their everyday life, with every adult Bulgar obliged to fight. The early Bulgars were exclusively horsemen: in their culture, the horse was considered a sacred animal and received special care. The supreme commander was the khan, who mustered the army with the help of the aristocracy.
Perfusion is the mass flow of blood through the tissues. Dissolved materials are transported in the blood much faster than they would be distributed by diffusion alone (order of minutes compared to hours). [18] The dissolved gas in the alveolar blood is transported to the body tissues by the blood circulation.
Often expressed in cm/s. This value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics. For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall.
The ensuing battle was a major defeat for the Bulgarians. Thousands of Bulgarian soldiers were captured and blinded by order of Basil II, who would subsequently be known as the "Bulgar-Slayer". Samuel survived the battle, but died two months later from a heart attack, reportedly brought on by the sight of his blind soldiers.
the rate and duration of outgassing on depressurization – the faster the ascent and the shorter the interval between dives the less time there is for absorbed gas to be offloaded safely through the lungs, causing these gases to come out of solution and form "micro bubbles" in the blood.
The process is the opposite of vasodilation, the widening of blood vessels. The process is particularly important in controlling hemorrhage and reducing acute blood loss. When blood vessels constrict, the flow of blood is restricted or decreased, thus retaining body heat or increasing vascular resistance.
The Bulgars retaliated, and under the leadership of Isbul, the minister of Malamir, they reached Adrianople. At this time, if not earlier, the Bulgars captured Philippopolis and its environs. Several surviving monumental inscriptions from this reign make reference to the Bulgar victories and others to the continuation of construction activities ...
