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.

Dread (film)

Dread is a 2009 British horror film directed and written by Anthony DiBlasi and starring Jackson Rathbone, Shaun Evans and Hanne Steen, based on the short story of the same name by Clive Barker. The story was originally published in 1984 in volume two of Barker's Books of Blood short story collections.

Plot

At a small college, Quaid and his friend Stephen do a "fear study" as a school project, recording people talking about their greatest fears. Quaid however is quite insane and wants to take the fear to 'the next level'. Quaid had seen his parents killed by an axe murderer as a child; this is his greatest fear, and he wants to learn what makes others afraid and what it takes for them to overcome their fear. Stephen's brother had died while drunk-driving, and Stephen wonders if his brother would still be alive if he had driven instead.

Fear

Fear is a feeling induced by perceived danger or threat that occurs in certain types of organisms, which causes a change in metabolic and organ functions and ultimately a change in behavior, such as fleeing, hiding or freezing from perceived traumatic events. Fear in human beings may occur in response to a specific stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to body or life. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat (also known as the fight-or-flight response), which in extreme cases of fear (horror and terror) can be a freeze response or paralysis.

In humans and animals, fear is modulated by the process of cognition and learning. Thus fear is judged as rational or appropriate and irrational or inappropriate. An irrational fear is called a phobia.

Psychologists such as John B. Watson, Robert Plutchik, and Paul Ekman have suggested that there is only a small set of basic or innate emotions and that fear is one of them. This hypothesized set includes such emotions as joy, sadness, fright, dread, horror, panic, anxiety, acute stress reaction and anger.
