What does SDH mean in medical terms?
A subdural hematoma (SDH) is a common neurosurgical disorder that often requires surgical intervention. It is a type of intracranial hemorrhage that occurs beneath the dura (essentially, a collection of blood over the surface of the brain) and may be associated with other brain injuries (see the images below).
What is full form of sth?
sth. written abbreviation for something. (Definition of sth from the Cambridge Advanced Learner’s Dictionary & Thesaurus © Cambridge University Press)
Why is SDH used?
SDH allows data streams with low bit rates to be combined into high-rate data streams. Since the entire network is synchronous, individual bit streams can be embedded into and extracted from high-rate data streams relatively easily. Initial specifications were developed back in 1985 in the USA under the term SONET.
What does SDH stand for in physiology?
A subdural hematoma (SDH) is a collection of blood below the inner layer of the dura but external to the brain and arachnoid membrane (see the images below). Subdural hematoma is the most common type of traumatic intracranial mass lesion.
Is SDH a stroke?
If a subdural hemorrhage involves significant amounts of blood, it can cause a stroke, due to the pressure.
What does English SDH mean?
Subtitles for Hearing Impaired Standard subtitles assume the viewer hears the audio. SDH is written in a format that understands that the viewer may not be able to hear the audio so it adds information about background sounds and who is speaking along with a translation of the script.
What STH means?
sth is an abbreviation for something. The sentence means tell somebody to do something. In real life, any person and any thing can be included in the sentence, for example, tell [your student] to [complete their homework]. A dictionary should explain this.
What is SDH and STM?
STM stands for Synchronous Transport Module. STM-1 is the base signal of the Synchronous Digital Hierarchy (SDH) protocol. SDH is a synchronous transmission protocol used in high speed communication systems and is primarily designed for use in Europe.
What’s the difference between SDH and CC?
The first difference is in appearance. Closed captions are typically displayed as white text on a black band, whereas SDH is usually displayed with the same proportional font of translated subtitles. SDH text is usually centered and locked in the lower bottom third of the screen.
What does SDG stand for?
The Sustainable Development Goals
The Sustainable Development Goals (SDGs) define the world we want. They apply to all nations and mean, quite simply, to ensure that no one is left behind.
What is Synchronous Digital Hierarchy (SDH)?
What is SDH? SDH is the short form of Synchronous Digital Hierarchy. This term is used in digital multiplexers installed in telephone exchanges. It is European standard similar to SONET which is an American standard. It supports different topologies viz. It multiplexes inputs having same bit rate and derived from common clock source.
What is SDH and PDH?
It explains basics of PDH and SDH and mentions useful difference between terms. PDH stands for Plesiochronous Digital Hierarchy and SDH stands for Synchronous Digital Hierarchy. Both PDH and SDH are terminologies associated with digital multiplexers used in exchanges.
What is RSOH in SDH?
Called regenerator section overhead (RSOH) in SDH terminology: 27 octets containing information about the frame structure required by the terminal equipment. Line overhead Called multiplex section overhead (MSOH) in SDH: 45 octets containing information about error correction and Automatic Protection Switching messages (e.g., alarms and maintenance messages) as may be required within the network.
What is the SDH network?
SDH (Synchronous Digital Hierarchy) is a standard technology for synchronous data transmission on optical media. It is the international equivalent of Synchronous Optical Network. Both technologies provide faster and less expensive network interconnection than traditional PDH (Plesiochronous Digital Hierarchy) equipment.
