Hydrelia shioyana

Hydrellia pakistanae is a species of fly in the shore fly family, Ephydridae. It is known as the Asian hydrilla leaf-mining fly. It is used as an agent of biological pest control against the noxious aquatic plant hydrilla (Hydrilla verticillata).The adult fly is about 1.5 millimeters long, dark gray in color with a shiny metallic gold or silver face. The female lays eggs on the leaves of hydrilla above the surface of the water. In about three days the tiny eggs hatch, releasing the small white or yellow-green larvae. The larva of this fly is a leaf miner. It enters the flesh of the leaf and digs tunnels through it as it feeds. The larva eats nearly all of the inner tissue of the leaf before moving on to the next leaf. One larva finishes an average of twelve leaves during its two-week larval period. It then pupates for about a week and emerges as an adult.This insect has been shown to be effective in the destruction of hydrilla. The photosynthetic ability of the leaf is reduced with even a small amount of larva damage, and the feeding injury becomes susceptible to opportunistic fungal infection. The buoyancy of the plant is reduced. As the infestation progresses, holes emerge in the hydrilla mat as plants begin to die and sink. As the hydrilla is eliminated native plants can move in to repopulate the area. This fly is native to India and Pakistan, and it is currently established in hydrilla-prone areas in the southeastern United States where it was successfully introduced. It does best in warm areas and tends to be much less effective in areas that get cold.

Hydriomena divisaria, the black-dashed hydriomena moth, is a moth in the family Geometridae. It is found in North America, where it has been recorded from southern Canada and the northern United States, south to Georgia in the east.The wingspan is 24–30 mm. The forewings are greyish-brown with a variable pattern of scalloped blackish lines. The greyish band in the antemedial area usually reaches the costa and the terminal line usually consists of a blurred pair dots. Adults have been recorded on wing mainly in April to July.The larvae feed on Abies balsamea, Pinus and Picea species.

Hydreliox is an exotic breathing gas mixture of helium, oxygen and hydrogen. For the Hydra VIII mission at 50 atmospheres of ambient pressure, the mixture used was 49% hydrogen, 50.2% helium, and 0.8% oxygen.It is used primarily for research and scientific deep diving, usually below 130 metres (430 ft). Below this depth, extended breathing of heliox gas mixtures may cause high pressure nervous syndrome (HPNS). Two gas mixtures exist that attempt to combat this problem: trimix and hydreliox.

In Hellenistic and Roman Arabia and Egypt, a hydreuma (plural hydreumata) was an enclosed (and often fortified) "watering station" (Classical Latin hydreuma from Ancient Greek ὕδρευμα from ὕδωρ, water ) at wadis in dry regions. A hydreuma was a manned and fortified watering hole or way station along a caravan route, providing a man-made oasis.In the 1st century CE, Pliny's Natural History described the current Roman sea-route to India, which had recently been established. The Via Hadriana, the route that linked the Nile with the Red Sea, was established by hydreumata. The annual caravan from Alexandria sailed up the Nile to Keft (Pliny's Coptus)."From Keft the journey is made with camels, stations being placed at intervals for the purpose of watering; the first, a stage of 22 miles, is called Hydreuma; the second is in the mountains, a day's journey on; [103] the third at a second place named Hydreuma, 85 miles from Keft; the next is in the mountains; next we come to Apollo's Hydreuma, 184 miles from Keft; again a station in the mountains ; then we get to New Hydreuma, 230 miles from Keft. There is also another old Hydreuma known by the name of Trogodyticum, where a guard is stationed on outpost duty at a caravanserai accommodating two thousand travellers; it is seven miles from New Hydreuma. Then comes the town of Berenice where there is a harbour on the Red Sea, 257 miles from Keft."The site of the "Hydreuma of Apollo", Apollos Hydreuma, mentioned by Pliny has yielded papyri in modern times. The hydreumata of Abu Qreiya and of Samut have been surveyed but not excavated. Abu Qreiya, one of these watering places, consists today of a concrete well in the wadi, drilled at the beginning of the 20th century; Aby Qreiya has been surveyed but not excavated.Another route dictated by hydreumata dug into the beds of wadis linked the barren mountain that was the sole source of Roman "imperial porphyry" with the Nile, the Via Porphyritis, the Porphyry Road.Along the way are seven hydreumata, or fortified wells, each one a day's march from the next. Outside the fortifications are lines of large stones to which oxen were tethered at night." (Werner 1998).

Hydreliox is an exotic breathing gas mixture of helium, oxygen and hydrogen. For the Hydra VIII mission at 50 atmospheres of ambient pressure, the mixture used was 49% hydrogen, 50.2% helium, and 0.8% oxygen.It is used primarily for research and scientific deep diving, usually below 130 metres (430 ft). Below this depth, extended breathing of heliox gas mixtures may cause high pressure nervous syndrome (HPNS). Two gas mixtures exist that attempt to combat this problem: trimix and hydreliox. Like trimix, hydreliox contains helium and oxygen and a third gas to counteract HPNS. The third gas in trimix is nitrogen and the third gas in hydreliox is hydrogen. Because hydrogen is the lightest element, it is easier to breathe than nitrogen under high pressure. To avoid the risk of explosion, as a rule of thumb hydrogen is only considered for use in breathing mixtures if the proportion of oxygen in the mixture is less than 5%. However, the pressure during the dive must be such that the partial pressure of 5% oxygen is sufficient to sustain the diver. (The flammability of the mixture also depends to some degree on the pressure)Hydreliox has been tested to simulated depths in excess of 700 metres (2,300 ft) in a chamber by COMEX S.A., a French diving company. Although breathing hydreliox improves the symptoms seen in HPNS, tests have shown that hydrogen narcosis becomes a factor at depths of 500 metres (1,600 ft).

In chemistry, a hydride is the anion of hydrogen, H−, or, more commonly, it is a compound in which one or more hydrogen centres have nucleophilic, reducing, or basic properties. In compounds that are regarded as hydrides, the hydrogen atom is bonded to a more electropositive element or group. Compounds containing hydrogen bonded to metals or metalloid may also be referred to as hydrides. Almost all of the elements form binary compounds with hydrogen, the exceptions being He, Ne, Ar, Kr, Pm, Os, Ir, Rn, Fr, and Ra.

species

Hydrelia latsaria is a moth in the family Geometridae. It is found in China.

Hydriomena plagiocausta

Hydriastele is a diverse and widespread genus of flowering plant in the palm family found throughout Australia and New Zealand, Melanesia, Polynesia, and Southeast Asia. It consisted of just nine species until 2004, when molecular research, supported by morphologic similarities, led taxonomists to include the members of the Gulubia, Gronophyllum, and Siphokentia genera. 48 species are now recognized, of which 38 are new combinations, two are new names and one is a new species.

Hydride vapour phase epitaxy (HVPE) is an epitaxial growth technique often employed to produce semiconductors such as GaN, GaAs, InP and their related compounds, in which hydrogen chloride is reacted at elevated temperature with the group-III metals to produce gaseous metal chlorides, which then react with ammonia to produce the group-III nitrides. Carrier gasses commonly used include ammonia, hydrogen and various chlorides.HVPE technology can significantly reduce the cost of production compared to the most common method of vapor deposition of organometallic compounds (MOCVD). Cost reduction is achieved by significantly reducing the consumption of NH3, cheaper source materials than in MOCVD, reducing the capital equipment costs, due to the high growth rate.Developed in the 1960s, it was the first epitaxial method used for the fabrication of single GaN crystals.Hydride Vapour Phase Epitaxy (HVPE) is the only III-V and III-N semiconductor crystal growth process working close to equilibrium. That means that the condensation reactions exhibit fast kinetics: one observe immediate reactivity to an increase of the vapour phase supersaturation towards condensation. This property is due to the use of chloride vapour precursors GaCl and InCl, of which dechlorination frequency is high enough so that there is no kinetic delay. A wide range of growth rates, from 1 to 100 microns per hour, can then be set as a function of the vapour phase supersaturation. Another HVPE feature is that growth is governed by surface kinetics: adsorption of gaseous precursors, decomposition of ad-species, desorption of decomposition products, surface diffusion towards kink sites. This property is of benefit when it comes to selective growth on patterned substrates for the synthesis of objects and structures exhibiting a 3D morphology. The morphology is only dependent on the intrinsic growth anisotropy of crystals. By setting experimental growth parameters of temperature and composition of the vapour phase, one can control this anisotropy, which can be very high as growth rates can be varied by an order of magnitude. Therefore, we can shape structures with various novel aspect ratios. The accurate control of growth morphology was used for the making of GaN quasi-substrates, arrays of GaAs and GaN structures on the micrometer and submicrometer scales, GaAs tips for local spin injection. Fast dechlorination property is also used for the VLS growth of GaAs and GaN nanowires with exceptional length.
