The combination of high gain, low noise, high frequency response or, equivalently, ultra-fast response, and large area of collection has maintained photomultipliers an essential place in low light level spectroscopy, confocal microscopy, Raman spectroscopy, fluorescence spectroscopy, nuclear and particle physics, astronomy, medical diagnostics ...
For each program, there is one PMT. While the MPEG-2 standard permits more than one PMT section to be transmitted on a single PID (Single Transport stream PID contains PMT information of more than one program), most MPEG-2 "users" such as ATSC and SCTE require each PMT to be transmitted on a separate PID that is not used for any other packets.
In enzymology, a phenol O-methyltransferase (EC 2.1.1.25) is an enzyme that catalyzes the chemical reaction. S-adenosyl-L-methionine + phenol S-adenosyl-L-homocysteine + anisole. Thus, the two substrates of this enzyme are S-adenosyl methionine and phenol, whereas its two products are S-adenosylhomocysteine and anisole.
The term "biobank" first appeared in the late 1990s and is a broad term that has evolved in recent years. [1] [2] One definition is "an organized collection of human biological material and associated information stored for one or more research purposes."

Protection motivation theory was developed by R.W. Rogers in 1975 in order to better understand fear appeals and how people cope with them. [1] However, Dr. Rogers would later expand on the theory in 1983 to a more general theory of persuasive communication.
In 2010, the pattern of AIPMT was changed. The examination was replaced by a two-tier or two-stage test – The AIPMT Prelims and the AIPMT Mains, in which the AIPMT Prelims was used to be objective exam and AIPMT Mains was used to be subjective exam. The candidates who could qualify the AIPMT Prelims were eligible to give the AIPMT Mains test.
Membrane fouling has traditionally been thought to occur through four mechanisms: 1) complete pore blocking, 2) standard blocking, 3) intermediate blocking, and 4) cake layer formation. [2] There are various types of foulants: biological (bacteria, fungi), colloidal (clays, flocs), scaling (mineral precipitates), and organic (oils ...
