In January 2004, UNISA merged with Technikon Southern Africa (Technikon SA, a polytechnic) and incorporated the distance education component of Vista University (VUDEC). The combined institution retained the name University of South Africa. It is now organised by college and by school; see below.
The negative helium dimer He 2 − is metastable and was discovered by Bae, Coggiola and Peterson in 1984 by passing He 2 + through cesium vapor. [19] Subsequently, H. H. Michels theoretically confirmed its existence and concluded that the 4 Π g state of He 2 − is bound relative to the a 2 Σ + u state of He 2. [20]
Hydrogen ditelluride or ditellane is an unstable hydrogen dichalcogenide containing two tellurium atoms per molecule, with structure H−Te−Te−H or (TeH) 2.Hydrogen ditelluride is interesting to theorists because its molecule is simple yet asymmetric (with no centre of symmetry) and is predicted to be one of the easiest to detect parity violation, in which the left handed molecule has ...
Hydrogen telluride is the inorganic compound with the formula H 2 Te.A hydrogen chalcogenide and the simplest hydride of tellurium, it is a colorless gas.Although unstable in ambient air, the gas can exist long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations.

This list of all two-letter combinations includes 1352 (2 × 26 2) of the possible 2704 (52 2) combinations of upper and lower case from the modern core Latin alphabet.A two-letter combination in bold means that the link links straight to a Wikipedia article (not a disambiguation page).
It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature , an acetyl group is called an ethanoyl group . An acetyl group contains a methyl group ( −CH 3 ) that is single-bonded to a carbonyl ( C=O ), making it an acyl group .
T,O,U,C,H,I,N,G is a 12-minute short film directed by Paul Sharits in 1968. [1] It uses many of the strategies characteristic of the structural film movement, including a static frame, flicker effects, flash frames and continual audio and visual repetition. The audio track consists exclusively of the filmmaker uttering the word "destroy" over ...
