Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.Web

Standard clinical definitions of ischemic stroke and TIA were used ( 8 ). Although TIA itself cannot cause death, the risk of both cardiac ischemia and a recurrent cerebral ischemic event is very high in TIA patients ( 9, 10 ). The distribution of causes of death in TIA and stroke patients is similar ( 4, 11 ), and mortality analyses often ...Web
