HVAC

HVAC (heating, ventilating, and air conditioning; also heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, (heating,ventilating and air-conditioning & Refrigeration) or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers, onboard vessels, and in marine environments such as aquariums, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

Ventilating or ventilation (the V in HVAC) is the process of "exchanging" or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.

Targetmaster

Targetmaster is a subline of the Transformers toyline that include Nebulan sidekicks who can transform into the Transformers' weapons.

1987 Targetmasters

The first Targetmasters assortment, released in 1987, included six new characters, and five existing ones from the 1986 line, whose toys were slightly remolded with larger peg holes to hold their new weapons, as well as an additional peg hole for each remold to mount its weapon in vehicle mode. In 2003, one of the two Japanese-exclusive Targetmasters from 1987 was added to the Autobot ranks. Unfortunately, the Targetmaster weapon he shares with Decepticon Cyclonus, also share names. To further add to the confusion, the printed names of Stepper and Artfire's weapon/partners in Japan are swapped. Cyclonus's partner Nightstick is called Nebulon (the name Fracas is erroneously given on Scourge's box) and paired with Stepper. Scourge's partner Fracas is called Nightstick and paired with Artfire.

The smaller Targetmaster partners were easily lost making them highly collectable and demand high prices on the secondary market.

Fino

Fino ("refined" in Spanish) is the driest and palest of the traditional varieties of Sherry and Montilla-Moriles fortified wine. They are consumed comparatively young, and unlike the sweeter varieties should be consumed soon after the bottle is opened as exposure to air can cause them to lose their flavour within hours.

Flor

The defining component of Fino sherries is the strain of yeast known as flor that floats in a layer on top of sherry in the wine barrel. Until the mid-19th century most sherry winemakers did not understand what this yellowish foam that randomly appeared in some of their barrels was. They would mark these barrels as "sick" and relegate them to their lowest bottlings of wine. It turned out that this strain of Saccharomyces yeast throve in air, and the more "head room" there was in the barrel the more likely it was to develop. Over time winemakers noticed that these wines were lighter and fresher than their other sherries, with the flor acting as a protective blanket over the wine that shielded it from excessive oxidation.

Fino (river)

The Fino is a river in eastern central Italy. Its source is near Monte Camicia in the province of Teramo in the Abruzzo region of Italy. The river flows northeast and then curves east before flowing past Bisenti. It continues flowing eastward and crosses into the province of Pescara near Elice. The river flows southeast until it joins the Tavo river and the two rivers become the Saline river.

FINO

In computer science, FINO (Sometimes seen as "FISH", for First In, Still Here) is a humorous scheduling algorithm. It is an acronym for "First In Never Out" as opposed to traditional "first in first out" (FIFO) and "last in first out" (LIFO) algorithms.

FINO works by withholding all scheduled tasks permanently. No matter how many tasks are scheduled at any time, no task ever actually takes place. This makes FINO extremely simple to implement, but useless in practice. A stateful FINO queue can be used to implement a memory leak.

A mention of FINO appears in the Signetics 25120 write-only memory joke datasheet.
