Helicopter

A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform.

The word helicopter is adapted from the French language hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ) "helix, spiral, whirl, convolution" and pteron (πτερόν) "wing". English-language nicknames for helicopter include "chopper", "copter", "helo", "heli", and "whirlybird".

Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration. Tandem rotor helicopters are also in widespread use due to their greater payload capacity. Coaxial helicopters, tiltrotor aircraft, and compound helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, and other types of multicopter have been developed for specialized applications such as unmanned drones.

Permaculture

Permaculture is a system of agricultural and social design principles centered around simulating or directly utilizing the patterns and features observed in natural ecosystems. The term permaculture (as a systematic method) was first coined by Australians David Holmgren, then a graduate student, and his professor, Bill Mollison, in 1978. The word permaculture originally referred to "permanent agriculture", but was expanded to stand also for "permanent culture", as it was understood that social aspects were integral to a truly sustainable system as inspired by Masanobu Fukuoka’s natural farming philosophy.

It has many branches that include but are not limited to ecological design, ecological engineering, environmental design, construction and integrated water resources management that develops sustainable architecture, regenerative and self-maintained habitat and agricultural systems modeled from natural ecosystems.

Mollison has said: "Permaculture is a philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless labor; and of looking at plants and animals in all their functions, rather than treating any area as a single product system."

Zone (vestment)

The Zone (Greek: ζώνη, zonē) is a form of girdle or belt common in the ancient eastern Mediterranean. The term occurs in Homer, for instance, as (Greek: ζώνην, zonēn) girdle and can also refer to the waist itself. Classical Greek had a verb (Greek: ζώννυσθαι, zonusthai) put a girdle around the loins, or "gird one's self."

In modern Greek and Church Slavonic the zone or (Поясъ, poyas - belt) is a liturgical belt worn as a vestment by priests and bishops of the Eastern Orthodox Church, Oriental Orthodox Churches and Eastern Catholic Churches. It is made of brocade with an embroidered or appliquéd cross in the center, with long ribbons at the ends for tying around the waist. It is worn over the sticharion and the epitrachelion and keeps them in place as the priest performs the Divine Liturgy. In this regard it is similar to the cincture of the Roman Catholic Church.

The zone is not worn for services when the priest is not fully vested, e.g. vespers or matins.

The zone worn by priests of the Old Believers of the Russian Tradition, have a unique design, with four pendant strips, two on each hip. This was the result of legislation passed under Empress Catherine the Great, mandating that the vestments of Old Believer clergy be sufficiently different from those of clergy belonging to the State Church, in order to avoid confusion.

DJ mix

A DJ mix or DJ mixset is a sequence of musical tracks typically mixed together to appear as one continuous track. DJ mixes are usually performed using a DJ mixer and multiple sounds sources, such as turntables, CD players, digital audio players or computer sound cards, sometimes with the addition of samplers and effects units, although it's possible to create one using sound editing software.

DJ mixing is significantly different from live sound mixing. Remix services were offered beginning in the late 1970s in order to provide music which was more easily beatmixed by DJs for the dancefloor. One of the earliest DJs to refine their mixing skills was DJ Kool Herc.Francis Grasso was the first DJ to use headphones and a basic form of mixing at the New York nightclub Sanctuary. Upon its release in 2000, Paul Oakenfold's Perfecto Presents: Another World became the biggest selling dj mix album in the US.

Music

A DJ mix is often put together with music from genres that fit into the more general term electronic dance music. Other genres mixed by DJ includes hip hop, breakbeat and disco. Four on the floor disco beats can be used to create seamless mixes so as to keep dancers locked to the dancefloor. Two of main characteristics of music used in dj mixes is a dominant bassline and repetitive beats. Music mixed by djs usually has a tempo which ranges from 120 bpm up to 160 bpm.
