2,4,6-Tribromoanisole

2,4,6-Tribromoanisole (TBA) is a chemical compound that is a brominated derivative of anisole. It is one of the chemicals responsible for cork taint.

Tribromoanisole is a fungal metabolite of 2,4,6-tribromophenol, which is used as a fungicide. It can be found in minute traces on packaging materials stored in the presence of fiberboard treated with 2,4,6-tribromophenol. These traces can cause an unpleasant mustiness in packaged foods.

Tribromoanisole is usually produced when naturally occurring airborne fungi or bacteria (usually Aspergillus sp., Penicillium sp., Actinomycetes, Botrytis cinerea, Rhizobium sp., or Streptomyces) are presented with brominated phenolic compounds, which they then convert into bromoanisole derivatives. The bromophenols can originate from various contaminants including those found in some pesticides and wood preservatives. They can also migrate from other objects such as shipping pallets treated by bromophenols.

Tribromoanisole has a very low odor detection threshold. It is 0.08-0.3 parts per trillion (ppt) in water and 2-6 ppt in wine (or 3.4-7.9 ng/l) so even very minute amounts can be detected. It causes unpleasant earthy, musty and moldy aromas.

To be announced

To be announced (TBA), to be confirmed (TBC), and to be determined (or to be decided, TBD) are placeholder terms used very broadly in event planning to indicate that although something is scheduled or expected to happen, a particular aspect of that remains to be arranged or confirmed.

TBA vs. TBC vs. TBD

These phrases are similar, but may be used for different degrees of indeterminacy:

Other similar phrases sometimes used to convey the same meaning, and using the same abbreviations, include "to be ascertained", "to be arranged", "to be advised", "to be adjudicated", "to be done", "to be decided", and "to be declared".

Use of the abbreviation "TBA" is formally reported in a reference work at least as early as 1955, and "TBD" is similarly reported as early as 1967.

Trockenbeerenauslese

Trockenbeerenauslese (literal meaning: "dried berries selection") is a German language wine term for a medium to full body dessert wine.

Trockenbeerenauslese is the highest in sugar content in the Prädikatswein category of the Austrian and German wine classifications.Trockenbeerenauslese wines, often called "TBA" for short, are made from individually selected grapes affected by noble rot, i.e. "botrytized" grapes.

This means that the grapes have been individually picked and are shrivelled with noble rot, often to the point of appearing like a raisin. They are therefore very sweet and have an intensely rich flavor, frequently with a lot of caramel and honey bouquet, stone fruit notes such as apricot, and distinctive aroma of the noble rot. The finest examples are made from the Riesling grape, as this retains plenty of acidity even at the extreme ripeness. Other grape varieties are also used, such as Scheurebe, Ortega, Welschriesling, Chardonnay, and Gewürztraminer and many are more prone to noble rot than Riesling since they ripen earlier.

Devolution

Devolution is the statutory granting of powers from the central government of a sovereign state to govern at a subnational level, such as a regional, local, or state level. It is a form of decentralization. Devolved territories have the power to make legislation relevant to the area.

Devolution differs from federalism in that the devolved powers of the subnational authority may be temporary and ultimately reside in central government, thus the state remains, de jure unitary. Legislation creating devolved parliaments or assemblies can be repealed or amended by central government in the same way as any statute.

Federal systems, or federations, differ in that state or provincial government is guaranteed in the constitution. Australia, Canada, India, the United States have federal systems, and have constitutions (as do some of their constituent states or provinces). They also have territories, with less power and authority than a state or province. Other examples of federations include Germany, Mexico, Brazil, Russia and Switzerland.

Devolution (disambiguation)

Devolution is the transfer of powers from a central government to a regional or a constituent national government.

Devolution (band)

Devolution is a US based industrial metal band established by Mike Garrett, later recording under the pseudonym of Mykill Mayhem. The first release from Devolution, entitled "Cerebrequiem", was in the genre of death metal and was released in 1996, featuring session musicians assembled from Mykill's previous band, Astaroth. Singer Larry Sapp (also a member of national recording artist Brutality) performed vocals, and Tony Laureano (also a member of Malevolent Creation, Dimmu Borgir, and Angelcorpse, and several other national recording artists in the death metal genre) lent his talents in recording the drums for the CD. Another death metal album was written, but technical difficulties and Laureano's touring schedule with Nile prevented this album from being released.

The next release was written and recorded in 1999, entitled, Self-Made Monster. This release was in the vein of the industrial metal genre, and was more well-received than the previous release. "Death's Shadow" was the first single to be promoted, and charted at number 1 on mp3.com for two months for the industrial genre from January 2000 to March 2000, with the second single, "Crack Rocks In The Engine Block" charting at number 2 in industrial charts, and the third single, "Flesh", charting in the top 10 in industrial charts on mp3.com, simultaneously.
