Platelets are important elements in the blood that are important for blood coagulation (clotting and prevention of bleeding). The normal platelet count ranges between 150,000 and 450,000 per microliter (one-millionth of a liter).
Known as Slauerhoffbrug (Slauerhoff Bridge), it is a tail bridge (kind of a bascule bridge) which can be quickly and efficiently raised by means of hydraulic mechanism to allow frequent passage of water traffic with minimum disruption to the vehicular traffic.uilt in 2000 the bridge is operated automatically almost every hour by two hydraulic cylinders which lift high in the air, a huge 15m by 15m portion of asphalt road. When closed the bridge deck merges seamlessly with the approach roads at both the ends.
From Wikipedia, the free encyclopedia. The Slauerhoffbrug (English: Slauerhoff Bridge) is a fully automatic bascule bridge (aka tail bridge) in the city of Leeuwarden in the Netherlands. It uses two arms to swing a section of road in and out of place within the road itself.This movable bridge is also known as the âSlauerhoffbrug âFlyingâ Drawbridgeâ.One of the main designers is Emile Asari. A tail bridge can quickly and efficiently be raised and lowered from one pylon (instead of hinges).This quickly allows water traffic to pass while only briefly blocking road traffic. The deck is 15 m by 15 m. It is painted in yellow and blue, representative of Leeuwarden's flag and seal.t uses two arms to swing a section of road in and out of place within the road itself.
