The need for cleaning arises because the medium that is transported through the tubes may cause deposits and finally even obstructions . In system engineering and in industry, particular demands are placed upon... | https://en.wikipedia.org/wiki/Tube_cleaning |
A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis . One possible design consists of a cylindrical cavity surrounded by heating coils that are embedded in a thermally insulating matrix. Temperature can be controlled via... | https://en.wikipedia.org/wiki/Tube_furnace |
In mathematics , particularly topology , the tube lemma , also called Wallace's theorem, is a useful tool in order to prove that the finite product of compact spaces is compact.
The lemma uses the following terminology:
Tube Lemma — Let X {\displaystyle X} and Y {\displaystyle Y} be topological spaces with Y {\displa... | https://en.wikipedia.org/wiki/Tube_lemma |
Tube sound (or valve sound ) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube -based audio amplifier . [ 1 ] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tu... | https://en.wikipedia.org/wiki/Tube_sound |

Tuberculin , also known as purified protein derivative , is a combination of proteins that are used in the diagnosis of tuberculosis . [ 1 ] This use is referred to as the tuberculin skin test and is recommended only for those at high risk. [ 2 ] Reliable administration of the skin test requires large amounts of traini... | https://en.wikipedia.org/wiki/Tuberculin |
The Tubular Exchanger Manufacturers Association (also known as TEMA ) is an association of fabricators of shell and tube type heat exchangers . [ 1 ] TEMA has established and maintains a set of construction standards for heat exchangers, known as the TEMA Standard. [ 2 ] TEMA also produces software for evaluation of fl... | https://en.wikipedia.org/wiki/Tubular_Exchanger_Manufacturers_Association |
The tubular pinch effect is a phenomenon in fluid mechanics , which has importance in membrane technology . This effect describes a tendency for suspended particles flowing through a pipe to reach an equilibrium distribution with the region of highest concentration of particles lies between the central axis and the wal... | https://en.wikipedia.org/wiki/Tubular_pinch_effect |
In organometallic chemistry , a tuck-in complex usually refers to derivatives of Cp* ligands wherein a methyl group is deprotonated and the resulting methylene attaches to the metal. The C 5 –CH 2 –M angle is acute. The term "tucked in" was coined to describe derivatives of organotungsten complexes . [ 1 ] Although mo... | https://en.wikipedia.org/wiki/Tuck-in_complex |
In mathematics , Tucker's lemma is a combinatorial analog of the Borsuk–Ulam theorem , named after Albert W. Tucker .
Let T be a triangulation of the closed n -dimensional ball B n {\displaystyle B_{n}} . Assume T is antipodally symmetric on the boundary sphere S n − 1 {\displaystyle S_{n-1}} . That means that the sub... | https://en.wikipedia.org/wiki/Tucker's_lemma |
