Helicodonta

Heliconia rostrata (also known as Hanging Lobster Claw or False Bird of Paradise) is an herbaceous perennial native to Peru, Bolivia, Colombia, Costa Rica, and Ecuador, and naturalized in Puerto Rico. Other Heliconias grow in the upright position (e.g. Heliconia bihai), their cup-shaped flower bracts storing water for birds and insects. This plant, however, has downward-facing flowers, the flowers thus providing a source of nectar to birds.Heliconias are known to those who grow them as a host flower to many birds, especially the Hummingbird. Because of its unique characteristics, it is often used as a specimen for tropical gardens.Along with the Kantuta flower, Heliconia rostrata, known as patujú, is the national flower of Bolivia.

Helicon (also transliterated Helikon) was a river of the Macedonian city Dion.There is also a river called Helikon [in Pieria]. After a course of seventy-five stades the stream hereupon disappears under the earth. After a gap of about twenty-two stades the water rises again, and under the name of Baphyras instead of Helikon flows into the sea as a navigable river. The people of Dion (Dium) say that at first this River flowed on land throughout its course. But, they go on to say, the women who killed Orpheus wished to wash off in it the blood-stains, and thereat the River sank underground, so as not to lend its waters to cleanse manslaughter.Helicon was briefly mentioned in some stories of Orpheus. After he was killed by some of Dionysus' followers, the women tried to wash their hands clean of the blood spilt. The river sank itself so as not to become tainted with the murdered man's blood.

Helicoidal flow is the cork-screw-like flow of water in a meander. It is one example of a secondary flow.Helicoidal flow is a contributing factor to the formation of slip-off slopes and river cliffs in a meandering section of the river. The helicoidal motion of the flow aids the processes of hydraulic action and corrasion on the outside of the meander, and sweeps sediment across the floor of the meander towards the inside of the meander, forming point bar deposits.

The Helicoidal Skyscraper was a planned but never materialized, 565 m (1,854 ft) high business center that was to have been built on the tip of Manhattan, New York City. It was a stillborn project developed between 1968 and 1974 by Italian architect Manfredi Nicoletti. It combined its aerodynamic shape with the technology of wired bridges, for the purpose of minimizing both the loads and structural bulk.Structural studies have been conducted by Italian engineer Sergio Musmeci. The building's structure concept is based on the body of a mammal and it explores the route of the maximum reduction of wind pressures and structural bulkiness.The central nucleus in steel and cement is compressed and made up of three interconnected cylindrical trunks which house all the vertical systems. Anchored to this nucleus are a group of trunks wired in steel which keep the external strips in traction where the latticed structures of the attics are located, which compress themselves towards the nucleus and collaborates with the overall static system.The wind pressure is minimized by the helix shape made by the trunks in the skyscraper, described by the three sails made by the overlapping of the habitable floors which revolve around the central trunk creating in planimetry a growing movement based on the golden spiral. The form reacts to the action of the wind, whatever direction it comes from, in a uniform and dissipative way. The result is the elimination of two of the main negative phenomena vis-à-vis the typology of skyscrapers: the excess static caused by the asymmetry of traditional structures of rectangular design, where the pressure of the wind is highest on the long side and lowest on the short one and the Von Karman effect typical of cylindrical structures which provokes a sinusoidal whirlwind and consequently lateral pulsating forces. The helicoidal shape, on the other hand, splits up the force of the wind in resistance, leeway and lift. In that way, the lift does not have an influence on the stability and decreases the weight transmitted to the foundations.The edifice, furthermore, different from the traditional skyscrapers, produces a chimney effect, un-polluting the air at ground level.The project extrapolates two typologies from areas never associated with buildings of great height: the twisting shape of the ship sail that escapes the wind and minimises its pressure, and the structure of the cable bridge that results in a significant saving of materials by collaborating the horizontal scaffolding with the rods and the supports.

A helicon is a low frequency electromagnetic wave that can exist in plasmas in the presence of a magnetic field. The first helicons observed were atmospheric whistlers, but they also exist in solid conductors or any other electromagnetic plasma.Helicons have the special ability to propagate through pure metals, given conditions of low temperature and high magnetic fields. Most electromagnetic waves in a normal conductor are not able to do this, since the high conductivity of metals (due to their free electrons) acts to screen out the electromagnetic field. Indeed, normally an electromagnetic wave would experience a very thin skin depth in a metal: the electric or magnetic fields are quickly reflected upon trying to enter the metal. (Hence the shine of metals.) However, skin depth depends on an inverse proportionality to the square root of angular frequency. Thus a low frequency electromagnetic wave may be able to overcome the skin depth problem, and thereby propagate throughout the material.A helicon discharge is an excitation of plasma by helicon waves induced through radio frequency heating. The difference between a helicon plasma source and an inductively coupled plasma (ICP) is the presence of a magnetic field directed along the axis of the antenna. The presence of this magnetic field creates a helicon mode of operation with higher ionization efficiency and greater electron density than a typical ICP. The Australian National University, in Canberra, Australia, is currently researching applications for this technology. A commercially developed magnetoplasmadynamic engine called VASIMR also uses helicon discharge for generation of plasma in its engine. Potentially, Helicon Double Layer Thruster plasma based rockets are suitable for interplanetary travel.

Helicon (also transliterated Helikon) was a river of the Macedonian city Dion.There is also a river called Helikon [in Pieria]. After a course of seventy-five stades the stream hereupon disappears under the earth. After a gap of about twenty-two stades the water rises again, and under the name of Baphyras instead of Helikon flows into the sea as a navigable river. The people of Dion (Dium) say that at first this River flowed on land throughout its course.
