"Giraffe Necking" is the term used to describe the appearance of a tube showing a number of uneven hotzones. It may occur for three main reasons. It may be an extreme type of the hot zone problem caused by extensive deactivation by catalyst poisoning or masking by a surface deposit. It may also be caused by channelling in the catalyst bed, where the gas passes preferentially through certain parts of the catalyst. When channelling occurs, the tube is cooled where gas is flowing and the reaction is occuring and overheats where the passage of gas is blocked. Channeling can be caused by packets of broken catalyst and dust or by accumulation of carbon. Lastly, especially in the case of old catalyst, giraffe necking may indicate that the catalyst is nearing the end of its active life and parts of it are falling below the minimum required activity and the catalyst requires charging.
the catalyst is used inside the reactor to activate the reaction of the ethylene and oxygen in order to produce ethylene oxide EO. those catalyst are small Wight balls fit inside the reactor tubes and by passing combined gases (oxygen, ethylene, nitrogen, and some other gases) they will react in a maintained temperature and pressure then form the EO. There are two types of catalyst: high selectivity catalyst low selectivity catalyst i wish that i answered the question & glad to answer any further question.
Galvanized tubes are steel tubes that are coated with zinc to protect them from rusting.
The eustachian tubes are the auditory tubes that link the nasopharynx to the middle ear.
The tubes are called as fallopian tubes.
It is observation because observsation means what you see.
Bilaterally Patent tubes means both fallopian tubes that are unblocked and unobstructed
tubes means the little out diameter, pipes means the large diameter.

It means that both tubes were cut.
Bilateral sterilization means both tubes (fallopian tubes or vasa deferens) were cut/tied/etc.
If you are pregnant and your tubes are tied afterwords, you should be fine. but that means you can't get pregnant again.
It means that both tubes were cut.
On a gas stove or oven the flash tubes are the means of connecting the pilot light. The flash tubes carry the flame from the pilot light to the individual burners.
As they are dwarf hamsters they are not as big as Syrian or other hamsters. This means that they may not be able to go in the tubes but it depends on the size of the tubes. Hope i helped :) x
if you had the game... do you... anyways, if you have it you'd realize they go in and out of tubes so think tubes what do plumbers do with them... which isn't the subject... he goes in the tubes and out... which means he's a plumber... I hope I answered your question, Skip
Bronchoconstriction means constricted bronchial tubes.
I think the term you're looking for is - vascular.
