A form of government where the monarch is elected, a modern example being the King of Cambodia, who is chosen by the Royal Council of the Throne; Vatican City is also often considered a modern elective monarchy. Self-proclaimed monarchy: A form of government where the monarch claims a monarch title without a nexus to the previous monarch dynasty.
The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] ( BOC group) is an acid -labile protecting group used in organic synthesis . The BOC group can be added to amines under aqueous conditions using di- tert -butyl dicarbonate in the presence of a base such as sodium hydroxide :
Binary offset carrier modulation [1] [2] (BOC modulation) was developed by John Betz in order to allow interoperability of satellite navigation systems. It is currently used in the US GPS system, Indian IRNSS system and in Galileo [3] and is a square sub-carrier modulation, where a signal is multiplied by a rectangular sub-carrier of frequency ...
1-Boc-4-AP. 1-Boc-4-AP ( tert-butyl 4- (phenylamino)piperidine-1-carboxylate) is a compound used as an intermediate in the manufacture of fentanyl, as well as various related derivatives such as butyrylfentanyl, furanylfentanyl, benzylfentanyl and homofentanyl, among others. It is an N-protected derivative of 4-anilinopiperidine which can be ...
Di-tert-butyl dicarbonate is a reagent widely used in organic synthesis. [ 1] Since this compound can be regarded formally as the acid anhydride derived from a tert -butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride. This pyrocarbonate reacts with amines to give N - tert -butoxycarbonyl or so-called Boc derivatives.
The Philippine Health Insurance Corporation ( PhilHealth) was created in 1995 to implement universal health coverage in the Philippines. It is a tax-exempt, government-owned and controlled corporation (GOCC) of the Philippines, and is attached to the Department of Health. On August 4, 1969, Republic Act 6111 or the Philippine Medical Care Act ...
BOC-3. A - Process Agent Service [clarification needed] is a United States federal filing that designates legal agents upon which process may be served. It pertains mostly to individuals or companies in the transportation and logistics industry, and it is often required before certain federal operating authorities can be granted within the ...
Multiplexed binary offset carrier (MBOC) modulation is a modulation design proposed for Galileo and modernized GPS satellite navigation signals, which combines a sine binary offset carrier SinBOC(1,1) signal with a SinBOC(6,1) signal, either via weighted sum/difference (the CBOC implementation) or via time-multiplexing (the TMBOC implementation).
