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.

El otro gol

"El otro gol" (English: The other goal or The another goal), known in some compilation albums as "Y otro gol" (English: And another goal), was a song made by Gandhi in honor to the Costa Rica national football team that classified to the 2002 Fifa World Cup. It was first released as "Y otro gol" in the album ¡Si se pudo! then as "El otro gol" in Bios. The song features a prominent fusion between reggae, pop and rock.

BIOS-3

BIOS-3 is a closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Russia.

Its construction began in 1965, and was completed in 1972. BIOS-3 consists of a 315 m³ habitat suitable for up to three persons, and was initially used for developing closed ecosystems capable of supporting humans. It was divided into 4 compartments — one of which is a crew area. Initially one other compartment was an algal cultivator, and the other two 'phytrons' for growing wheat or vegetables. Later the algal cultivator was converted into a third phytron. A level of light comparable to sunlight was supplied in each of the 4 compartments by 20 kW xenon lamps, cooled by water jackets. The facility used 400 kW of electricity, supplied by a nearby hydroelectric power station.

Chlorella algae were used to recycle air breathed by humans, absorbing carbon dioxide and replenishing it with oxygen through photosynthesis. The algae were cultivated in stacked tanks under artificial light. To achieve a balance of oxygen and carbon dioxide, one human needed 8 m² of exposed Chlorella. Air was purified of more complex organic compounds by heating to 600 °C in the presence of a catalyst. Water and nutrients were stored in advance and were also recycled. By 1968, system efficiency had reached 85% by recycling water. Dried meat was imported into the facility, and urine and feces were generally dried and stored, rather than being recycled.
