The Centers for Medicare & Medicaid Services (CMS) issued a final rule CMS-1629-F to update the Medicare hospice payment rates and wage index (Final FY 2016 Hospice Wage Index [ZIP, 269KB]) for fiscal year (FY) 2016. The final rule reflects the ongoing efforts of CMS to support beneficiary access to hospice care.
Silicon is a chemical element with symbol Si and atomic number 14. It is a tetravalent metalloid, more reactive than germanium, the metalloid directly below it in the table.Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823.easured by mass, silicon makes up 27.7% of the Earth's crust and is the second most abundant element in the crust, with only oxygen having a greater abundance. Silicon is usually found in the form of complex silicate minerals, and less often as silicon dioxide (silica, a major component of common sand).
Thyristor or silicon controlled rectifier is a multilayer semiconductor device and is similar to the transistor. Silicon controlled rectifier consists of three terminals (anode, cathode, and gate) unlike the two terminal diode (anode and cathode) rectifier.he silicon controlled rectifier or thyristor is represented by the symbol as shown in the figure. Silicon Controlled Rectifier. Silicon controlled rectifier is also a unidirectional device as it conducts only in one direction.
