Parameters that can be varied at each radar site are those shown in red. Most stratiform rain events in the Ohio River Valley have a reflectivity signal strength of dBZ with occasional peaks to 45dBZ, but rarely anything higher that isn't "brightbanding". Refer to Section 7. The bias correction factor can only be computed if there are at least 10 gage-radar pairs with both values 0. Sometimes, data has to be searched back several hours to find at least 10 such pairs. The actual number of pairs used in computing this bias factor is shown following the sign. The number of hours searched is shown preceding the bias factor.

Values under 1. It is commonly used in corrosive environments. Zirconium alloys can be found in pipes, fittings and heat exchangers, according to Chemicool.

Aug 17,   Zircon, a common accessory mineral in crustal rocks, records plentiful and critical information on the Earth's history. The isotopes of its major component, Zr, could be another powerful but unexplored tracer. We apply high-precision, high-spatial-resolution, in situ laser ablation Zr isotope measurements of magmatic zircons in continental arc plutonic rocks.

Zirconium is also used in steel alloys, colored glazes, bricks, ceramics, abrasives, flashbulbs, lamp filaments, artificial gemstones and some deodorants, according to Minerals Education Coalition.

Other uses for zirconium include catalytic converters, furnace bricks, lab crucibles, surgical instruments, television glass, removing residual gases from vacuum tubes, and as a hardening agent in alloys such as steel, according to Lenntech.

Also, zirconium carbonate is used to treat poison ivy, according to the Jefferson Laboratory. Zirconium has been found in S-type stars, the sun, meteorites and in lunar rocks, according to the Los Alamos National Laboratory.

93 Zr is a radioisotope of zirconium with a half-life of million years, decaying through emission of a low-energy beta particle. 73of decays populate an excited state of niobium, which decays with a halflife of 14 years and a low-energy gamma ray to the stable ground state of 93 Nb, while the remaining 27of decays directly populate the ground mcauctionservicellc.comrd atomic weight A(Zr): (2).

Lunar rocks appear to have a surprisingly high zircon content compared to terrestrial rocks, according to analysis of lunar rock samples from the various Apollo missions. On Earth, sources for zirconium are primarily the minerals zircon and baddeleyite zirconium dioxidewhich are mined in the United States, Australia, Brazil, South Africa, Russia, and Sri Lanka, according to Minerals Education Coalition.

Zircon, a gemstone, comes in blue, yellow, green, brown, orange, red and occasionally purple varieties. The word comes from the Persian "zargun" or gold color. It has been used in jewelry and other decoration for centuries, according to Peter van der Krogta Dutch historian.

It comes closer to resembling a diamond than any other natural gem, according to Minerals. During the Middle Ages, zircon was even believed to induce sleep, promote wealth, honor and wisdom, and to drive away plagues and evil spirits.

Martin Heinrich Klaproth, a German chemist, discovered zirconium in in a sample of zircon from Sri Lanka, according to Chemicool. The sample's composition was found to be 25 percent silica, 0. The low specific activity and low energy of its radiations limit the radioactive hazards of this isotope.

Nuclear fission produces it at a fission yield of 6. Nuclear reactors usually contain large amounts of zirconium as fuel rod cladding see zircaloyand neutron irradiation of 92 Zr also produces some 93 Zr, though this is limited by 92 Zr's low neutron capture cross section of 0.

Mobility in soil is relatively low, so that geological disposal may be an adequate solution. From Wikipedia, the free encyclopedia.

The table above shows WSRD Z/R relationships for sites used in the OHRFC radar mosaic. A Z/R relationship is a empirical formula that is used to estimate rainfall rates from reflectivity signal strength.
