Turbofan engines often feature an exhaust mixer, where the bypass (cold/slow) air is mixed with the core (hot/fast) exhaust gases, before exhausting to atmospheric pressure through a common (mixed flow) propelling nozzle.
The mixer reduces the velocity of the core exiting air, and consequently, reducing the amount of noise produced. Additionally, the temperature of the exhaust is reduced, rendering the thermal signature of the aircraft to be lower as well. This attribute is critical in military aircraft where thermal detection or heat-seeking weapons are used.
Ideally, a mixer is also a performance benefit to increasing thrust. The exhaust thrust from a jet engine is equal to exhaust mass flow times exhaust velocity, ie, Thrust=mv, while the energy to make that thrust is given by Energy=(1/2)m(v^2). A mixer helps reduce the fastest exhaust velocities from the core of the engine, while making the average exhaust velocity faster, producing more thrust with the same energy.
A mixer dance, dance mixer or simply mixer is a kind of participation dance in a social dance setting that involves changing partners as an integral part. Mixing can be built into the dance choreography or can be structured to occur more randomly. Mixers allow dancers to meet new partners and allow beginners to dance with more advanced dancers. Some people may take advantage of mixers to assess dance skills of other persons without fear of being stuck with a poor match for an entire dance.
Some mixer dances have traditional names.
The descriptions of "mixing procedures" vary, however there are several common basic rules.
The basic rule of dance etiquette "thou shalt never say 'no'" is partially waived during certain procedures of the mixer: if you have already danced with the person, you may smile to each other and skip the choice. The reasoning is that the basic purpose of the mixer — to make people dance with many new partners — has the precedence.
Sometimes a "lost and found" place is designated (e.g., the centre of the dance circle), where unmatched dancers may find each other. Reasons for the occurrence of "unmatched dancers" include the mixing process inherent in the particular dance, gender imbalance, and dancer confusion.
Three official singles have been released from As If: "All U Writers", a 5 1/2 minute (5 minutes on the album) long song featuring vocals from Teresa Eggers, released 28 April 2015. "Freedom '15", a groovy leviathan of a disco track, released 30 July 2015, and features vocals from Yolanda Harris Dancy and Taletha Manor. A lyric video for "Freedom '15" was uploaded 20 August 2015. The third single from the album, "Bam City", was released 30 September 2015, with an accompanying music video. "Ooo", a grooving love song, was released with an accompanying music video on November 16, 2015.
One promotional single has been released from the As If: "Sick Ass Moon", an "R&B-tinted house track", released with "Freedom '15" on 30 July 2015.
In a positive review for Exclaim!, Daniel Sylvester called the album "one of the most enjoyable, if schizophrenic, dance albums of the year."
The episode received mixed reviews from critics. Lisa Respers France of CNN and Blair Baldwin of Zap2it both received the episode positively. Todd VanDerWerff of The A.V. Club, Entertainment Weekly's Tim Stack and James Poniewozic of Time highlighted continuity issues with the show, while VanDerWerff and Henrik Batallones of BuddyTV deemed "Funk" a set-up episode for the season finale. Bobby Hankinson of the Houston Chronicle gave a more positive review, but still found "Funk" lacking compared to previous episodes, a sentiment shared by Aly Semigran of MTV.
