Genes involved in iron metabolism disorders include HFE and TFR2.Hepcidin is the master regulator of iron metabolism and, therefore, most genetic forms of iron overload can be thought of as relative hepcidin deficiency in one way or another[1]. For instance, a severe form of iron overload, juvenile hemochromatosis, is a result of severe hepcidin deficiency. The majority of cases are caused by mutations in the hemojuvelin gene (HJV or RGMc/repulsive guidance molecule c).

Iron mining in the United States produced 42.5 million metric tons of iron ore in 2015, worth US$3.8 billion. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah. Most of the iron ore was mined in northern Minnesota’s Mesabi Range. Net exports (exports minus imports) were 3.9 million tons. US iron ore made up 2.5 percent of the total mined worldwide in 2015. Employment as of 2014 was 5,750 in iron mines and iron ore treatment plants.US iron ore mining is dominated by the Precambrian banded iron formation deposits around Lake Superior, in Minnesota and Michigan; such deposits were also formerly mined in Wisconsin. For the past 50 years, more than 90 percent of US iron ore production has been mined from the Lake Superior deposits. None of the iron ore now mined in the US is “direct shipping” ore ready to be fed into the iron- and steel-making process. The ore is concentrated to raise the iron content before use. All the iron ore currently mined is from open pits.

The iron condor is an option trading strategy utilizing two vertical spreads – a put spread and a call spread with the same expiration and four different strikes. A long iron condor is essentially selling both sides of the underlying instrument by simultaneously shorting the same number of calls and puts, then covering each position with the purchase of further out of the money call(s) and put(s) respectively. The converse produces a short iron condor.The position is so named because of the shape of the profit/loss graph, which loosely resembles a large-bodied bird, such as a condor. In keeping with this analogy, traders often refer to the inner options collectively as the "body" and the outer options as the "wings". The word iron in the name of this position indicates that, like an iron butterfly, this position is constructed using both calls and puts, by combining a bull put spread with a bear call spread. The combination of these two credit spreads makes the long iron condor (and the long iron butterfly) a credit spread, despite the fact that it is "long." This distinguishes the position from a plain Condor position (and the plain Butterfly), which would be constructed with all calls or all puts, by combining either a bull call spread with a bear call spread or a bull put spread with a bear put spread. Because the long, plain Condor (and Butterfly) combine a debit spread with a credit spread, that overall position is instead entered at a net debit (though usually small).One of the practical advantages of an iron condor over a single vertical spread (a put spread or call spread), is that the initial and maintenance margin requirements for the iron condor are often the same as the margin requirements for a single vertical spread, yet the iron condor offers the profit potential of two net credit premiums instead of only one. This can significantly improve the potential rate of return on capital risked when the trader doesn't expect the underlying instrument's spot price to change significantly.Another practical advantage of the iron condor is that if the spot price of the underlying is between the inner strikes towards the end of the option contract, the trader can avoid additional transaction charges by simply letting some or all of the options contracts expire. If the trader is uncomfortable, however, with the proximity of the underlying's spot price to one of the inner strikes and/or is concerned about pin risk, then the trader can close one or both sides of the position by first re-purchasing the written options and then selling the purchased options.

Iron oxide adsorption is a water treatment process that is used to remove arsenic from drinking water. Arsenic is a common natural contaminant of well water and is highly carcinogenic. Iron oxide adsorption treatment for arsenic in groundwater is a commonly practiced removal process which involves the chemical treatment of arsenic species such that they adsorb onto iron oxides and create larger particles that may be filtered out of the water stream.The addition of ferric chloride, FeCl3, to well water immediately after the well at the influent to the treatment plant creates ferric hydroxide, Fe(OH)3, and hydrochloric acid, HCl.3H2O + FeCl3 → Fe(OH)3 + 3HClFe(OH)3 in water is a strong adsorbent of arsenate, As(V), provided that the pH is low. HCl lowers pH, assuring arsenic adsorption, and the disassociated chlorine oxidizes iron in solution from Fe+2 to Fe+3, which then may bond with hydroxide ions, OH−, thus creating more adsorbent.This adjustment also lowers the pH of the well water, decreasing alkalinity and allowing more cationic species such Fe(+) or As(+) as to exist freely within the flow. Low pH also decreases the solubility of some iron and arsenic species as well as increasing the adsorptive reactivity of arsenate, As(V).Additional oxidation of Fe+2 to Fe+3, also referred to as iron(II) and iron(III), is induced by the addition of sodium hypochlorite, NaOCl, at the well head. NaOCl is usually added for disinfection although it may be used in this case towards the objectives of a distribution system free chlorine residual of 1 mg/L and the oxidation of aqueous As(III) to As(V), and aqueous iron Fe+2 to Fe+3, which will bond with hydroxide for further adsorption.The filter media usually consists of anthracite, iron-manganese oxidizing sand, and garnet sand over support gravel.

Iron has a long and varied tradition in the mythology and folklore of the world.

Iron boride refers to various inorganic compounds with the formula FexBy. Two main iron borides are FeB and Fe2B. Some iron borides possess useful properties such as magnetism, electrical conductivity, corrosion resistance and extreme hardness. Some iron borides have found use as hardening coatings for iron. Iron borides have properties of ceramics such as high hardness, and properties of metal properties, such as thermal conductivity and electrical conductivity.

In 2014, the Iron and steel industry in the United States was the world’s third-largest producer of raw steel (after China and Japan), and the sixth-largest producer of pig iron. The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore. The United States is a major importer of iron and steel, and iron and steel products.Employment as of 2014 was 149,000 people employed in iron and steel mills, and 69,000 in foundries. The value of iron and steel produced in 2014 was $113 billion.As of 2015, major steel-makers in the United States included: AK Steel, Carpenter Technology, Commercial Metals Company, and Nucor, Steel Dynamics, and U.S. Steel.

In molecular biology, the iron dependent repressors are a family of bacterial and archaeal transcriptional repressors.At their N-terminus they contain a dtxR-type HTH domain. This is a DNA-binding, winged helix-turn-helix (wHTH) domain of about 65 amino acids present in metalloregulators of the dtxR/mntR family. The domain is named after Corynebacterium diphtheriae dtxR, an iron-specific diphtheria toxin repressor, and Bacillus subtilis mntR, a manganese transport regulator. Iron-responsive metalloregulators such as dtxR and ideR occur in Gram-positive bacteria of the high GC branch, while manganese-responsive metalloregulators like mntR are described in diverse genera of Gram-positive and Gram-negative bacteria and also in Archaea. The metalloregulators like dtxR/mntR contain the DNA-binding dtxR-type HTHdomain usually in the N-terminal part. The C-terminal part contains a dimerisation domain with two metal-binding sites, although the primary metal-binding site is less conserved in the Mn(II)-regulators. Fe(II)-regulated proteins contain an SH3-like domain as a C-terminal extension, which is absent in Mn(II)-regulated mntR.Metal-ion dependent regulators orchestrate the virulence of several important human pathogens. The dtxR protein regulates the expression of diphtheria toxin in response to environmental iron concentrations. Furthermore, dtxR and ideR control iron uptake. Homeostasis of manganese, which is an essential nutrient, is regulated by mntR. A typical dtxR-type metalloregulator binds two divalent metal effectors per monomer, upon which allosteric changes occur that moderate binding to the cognate DNA operators. Iron-bound dtxR homodimers bind to an interrupted palindrome of 19 bp, protecting a sequence of ~30 bp. The crystal structures of iron-regulated and manganese-regulated repressors show that the DNA binding domain contains three alpha-helices and a pair of antiparallel beta-strands. Helices 2 and 3 comprise the helix-turn-helix motif and the beta-strands are called the wing. This wHTH topology is similar to the lysR-type HTH. Most dtxR-type metalloregulators bind as dimers to the DNA major groove.Several proteins are known to contain a dtxR-type HTH domain. These include: Corynebacterium diphtheriae dtxR, a diphtheria toxin repressor, which regulates the expression of the high-affinity iron uptake system, other iron-sensitive genes, and the bacteriophage tox gene. Metal-bound dtxR represses transcription by binding the tox operator; if iron is limiting, conformational changes of the wHTH disrupt DNA-binding and the diphtheria toxin is produced. Mycobacterium tuberculosis ideR, an iron-dependent regulator that is essential for this pathogen. The regulator represses genes for iron acquisition and activates iron storage genes, and is a positive regulator of oxidative stress responses. Bacillus subtilis mntR, a manganese transport regulator, binds Mn2+ as an effector and is a transcriptional repressor of transporters for the import of manganese. Treponema pallidum troR, a metal-dependent transcriptional repressor. Archaeoglobus fulgidus MDR1 (troR), a metal-dependent transcriptional repressor, which negatively regulates its own transcription.

The iron peak is a local maximum in the vicinity of Fe (Cr, Mn, Fe, Co and Ni) on the graph of the abundances of the chemical elements, as seen below.For elements lighter than iron on the periodic table, nuclear fusion releases energy while fission consumes it. For iron, and for all of the heavier elements, nuclear fusion consumes energy, but nuclear fission releases it. Chemical elements up to the iron peak are produced in ordinary stellar nucleosynthesis. Heavier elements are produced only during supernova nucleosynthesis. This is why we have more iron peak elements than in its neighbourhood.

Ashdown Forest formed an important part of the Wealden iron industry that operated from pre-Roman times until the early 18th century. The industry reached its peak in the two periods when the Weald was the main iron-producing region of Britain, namely in the first 200 years of the Roman occupation (1st to 3rd centuries AD) and during Tudor and early Stuart times. Iron-smelting in the former period was based on bloomery technology, while the latter depended for its rapid growth on the blast furnace, when the Ashdown area became the first in England to use this technology.The Forest was a particularly favourable location for iron production because of the presence of iron-ore in the local geology of sandstone Ashdown Beds and overlying Wadhurst Clay, the availability of large expanses of woodland for the production of charcoal, and deep, steep-sided valleys that had been incised into the relatively soft sandstone which together with locally high rainfall made it practical to dam streams to form lakes to provide water power for furnaces and forges.

Iron chelate, also known as chelated iron, is a soluble complex of iron, sodium and a chelating agent such as ethylenediaminetetraacetate (EDTA), EDDHA, or others, used to make the iron soluble in water and, for the purposes of agriculture, accessible to plants.It is encountered as a dark brownish powder, and can be a mild irritant to the skin, respiratory membranes or eyes.

"Iron horse" is an iconic literary term (currently transitioning into an archaic reference) for a steam locomotive, originating in the early Victorian culture (1825–35) when horses still powered most machinery, excepting windmills and stationary steam engines. The term was common and popular in both British and North American literary articles.

In sociology, the iron cage is a term coined by Max Weber for the increased rationalization inherent in social life, particularly in Western capitalist societies. The "iron cage" thus traps individuals in systems based purely on teleological efficiency, rational calculation and control. Weber also described the bureaucratization of social order as "the polar night of icy darkness".The original German term is stahlhartes Gehäuse; this was translated into "iron cage", an expression made familiar to English language speakers by Talcott Parsons in his 1930 translation of Weber's The Protestant Ethic and the Spirit of Capitalism. This choice has been questioned recently by scholars who prefer the more direct translation: "shell as hard as steel".Weber (in Parsons' translation) wrote:In Baxter’s view the care for external goods should only lie on the shoulders of the 'saint like a light cloak, which can be thrown aside at any moment.' But fate decreed that the cloak should become an iron cage.Weber became concerned with social actions and the subjective meaning that humans attach to their actions and interaction within specific social contexts. He also believed in idealism, which is the belief that we only know things because of the meanings that we apply to them. This led to his interest in power and authority in terms of bureaucracy and rationalization.

Iron armour was a type of armour used on warships and, to a limited degree, fortifications. The use of iron gave rise to the term ironclad as a reference to a ship 'clad' in iron. The earliest material available in sufficient quantities for armouring ships was iron, wrought or cast. While cast iron has never been used for naval armour, it did find a use in land fortifications, presumable due to the lower cost of the material.

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% to 5% copper, with gold contents ranging from 0.1 to 3+ grams per tonne (parts per million). These ore bodies tend to express as cone-like, blanket-like breccia sheets within granitic margins, or as long ribbon-like breccia or massive iron oxide deposits within faults or shears.The tremendous size, relatively simple metallurgy and relatively high grade of IOCG deposits can produce extremely profitable mines.Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare earth metals, although these accessories are typically subordinate to copper and gold in economic terms.Some examples include the Olympic Dam, South Australia and La Candelaria, Chile deposits.

Iron fertilisation

The iron catastrophe was a postulated major event early in the history of Earth. The original accretion of the Earth's material into a spherical mass is thought to have resulted in a relatively uniform composition. While residual heat from the collision of the material that formed the Earth was significant, heating from radioactive materials in this mass gradually increased the temperature until a critical condition was reached. As material became molten enough to allow movement, the denser iron and nickel, evenly distributed throughout the mass, began to migrate to the center of the planet to form the core. The gravitational potential energy released by the sinking of the dense NiFe globules, along with any cooler, denser solid material, is thought to have been a runaway process, increasing the temperature of the protoplanet above the melting point of most components, resulting in the rapid formation of a molten iron core covered by a deep global silicate magma. This event, an important process of planetary differentiation, occurred at about 500 million years into the formation of the planet.

Iron oxychloride is the inorganic compound with the formula FeOCl. This purple solid adopts a layered structure, akin to that of cadmium chloride. The material slowly hydrolyses in moist air. The solid intercalates electron-donors such as tetrathiafulvalene and even pyridine to give mixed valence charge-transfer salts. Intercalation is accompanied by a marked increase in electrical conductivity and a color change to black.FeOCl is prepared by heating iron(III) oxide with ferric chloride at 370 °C over the course of several days:Fe2O3 + FeCl3 → 3 FeOCl

Iron (Fe) deficiency is a plant disorder also known as "lime-induced chlorosis". It can be confused with manganese deficiency. A deficiency in the soil is rare but iron can be unavailable for absorption if soil pH is not between about 5 and 6.5. A common problem is excessive alkalinity of the soil (the pH is above 6.5). Also, iron deficiency can develop if the soil is too waterlogged or has been overfertilised. Elements like calcium, zinc, manganese, phosphorus, or copper can tie up iron if they are present in high amounts.Iron is needed to produce chlorophyll, hence its deficiency causes chlorosis. For example, iron is used in the active site of glutamyl-tRNA reductase, an enzyme needed for the formation of 5-Aminolevulinic acid which is a precursor of heme and chlorophyll.

Iron fertilization is the intentional introduction of iron to the upper ocean to stimulate a phytoplankton bloom. This is intended to enhance biological productivity, which can benefit the marine food chain and is under investigation in hopes of increasing carbon dioxide removal from the atmosphere. Iron is a trace element necessary for photosynthesis in all plants. It is highly insoluble in sea water and is often the limiting nutrient for phytoplankton growth.

Iron oxides are chemical compounds composed of iron and oxygen. All together, there are sixteen known iron oxides and oxyhydroxides.Iron oxides and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, in thermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide. Iron oxides are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.

On one rainy day with less business than usual, Huang Zhangnian had to continually recook red cooked eggs (滷蛋) to keep them warm after taking them out of the soy sauce broth. The recooking and drying process eventually resulted in shrunken eggs that were dark, flavourful, and chewy, which was extremely popular with the locals. Huang eventually founded a new business based on her iron egg recipe, selling them under the brand Apotiedan (阿婆鐵蛋; "Grandma's iron eggs"). They can only be created by the use of "chicken, pigeon or quail eggs" and not from duck eggs. The popularity of iron eggs has risen and they can be found in other countries besides Taiwan, such as in Africa and the Middle East.The dish consists of small eggs that have been repeatedly stewed in a mix of spices and air-dried. The resulting eggs are dark brown on the outside, chewy in texture, and very flavourful compared to standard boiled eggs. It has been said to taste "sweet, spicy and slightly salty with a concentrated egg flavour—a great snack with drinks".

Iron fertilization is the intentional introduction of iron to the upper ocean to stimulate a phytoplankton bloom. This is intended to enhance biological productivity, which can benefit the marine food chain and is under investigation in hopes of increasing carbon dioxide removal from the atmosphere. Iron is a trace element necessary for photosynthesis in all plants. It is highly insoluble in sea water and is often the limiting nutrient for phytoplankton growth. Large algal blooms can be created by supplying iron to iron-deficient ocean waters.A number of ocean labs, scientists and businesses are exploring fertilization as a means to sequester atmospheric carbon dioxide in the deep ocean, and to increase marine biological productivity which is hypothesized by some to decline as a result of climate change. Since 1993, thirteen international research teams have completed ocean trials demonstrating that phytoplankton blooms can be stimulated by iron addition. However, controversy remains over the effectiveness of atmospheric CO2 sequestration and ecological effects. The most recent open ocean trials of ocean iron fertilization were in 2009 (January to March) in the South Atlantic by project Lohafex, and in July 2012 in the North Pacific off the coast of British Columbia, Canada, by the Haida Salmon Restoration Corporation (HSRC).Fertilization also occurs naturally when upwellings bring nutrient-rich water to the surface, as occurs when ocean currents meet an ocean bank or a sea mount. This form of fertilization produces the world's largest marine habitats. Fertilization can also occur when weather carries wind blown dust long distances over the ocean, or iron-rich minerals are carried into the ocean by glaciers, rivers and icebergs.

The iron oxide cycle (Fe3O4/FeO) is the original two-step thermochemical cycle proposed for use for hydrogen production. It is based on the reduction and subsequent oxidation of iron ions, particularly the reduction and oxidation from Fe3+ to Fe2+. The ferrites, or iron oxide, begins in the form of a spinel and depending on the reaction conditions, dopant metals and support material forms either Wüstites or different spinels.

An iron hydride is a chemical system which contains iron and hydrogen in some associated form.Because of the common occurrence of those two elements in the universe, possible compounds of hydrogen and iron have attracted attention. A few molecular compounds have been detected in extreme environments (such as stellar atmospheres) or detected in small amounts at very low temperatures. The two elements form a metallic alloy above 35000 atmospheres of pressure, that has been advanced as a possible explanation for the low density of Earth's "iron" core. However those compounds are unstable when brought to ambient conditions, and eventually decompose into the separate elements.Small amounts of hydrogen (up to about 0.08% by weight) are absorbed into iron as it solidifies from molten state. Although the H2 is simply an impurity, its presence can affect the mechanical properties of the material.Despite the fleeting nature of binary iron hydrides, there are many fairly stable complexes containing iron-hydrogen bonds (and other elements).

Iron meteorites are meteorites that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Iron meteorites originate from planetary cores of planetesimals.The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, before the development of smelting that signaled the beginning of the iron age.

Ashdown Forest formed an important part of the Wealden iron industry that operated from pre-Roman times until the early 18th century. The industry reached its peak in the two periods when the Weald was the main iron-producing region of Britain, namely in the first 200 years of the Roman occupation (1st to 3rd centuries AD) and during Tudor and early Stuart times.

The iron catastrophe was a postulated major event early in the history of Earth. The original accretion of the Earth's material into a spherical mass is thought to have resulted in a relatively uniform composition. While residual heat from the collision of the material that formed the Earth was significant, heating from radioactive materials in this mass gradually increased the temperature until a critical condition was reached.

Iron armour was a type of armour used on warships and, to a limited degree, fortifications. The use of iron gave rise to the term ironclad as a reference to a ship 'clad' in iron. The earliest material available in sufficient quantities for armouring ships was iron, wrought or cast. While cast iron has never been used for naval armour, it did find a use in land fortifications, presumable due to the lower cost of the material. One well known example of cast-iron armour for land use is the Gruson turret, first tested by the Prussian government in 1868. Armoured ships may have been built as early as 1203, in the far east. In the West, they first become common when France launched the first ocean-going ironclad La Gloire in 1859. The British Navy responded with HMS Warrior in 1860, triggering a naval arms race with bigger, more heavily armed and armoured ironclads.Early experiments showed that wrought iron was superior to cast iron, and wrought iron was subsequently adopted for naval use. British efforts at perfecting iron armour were headed by a government Special Committee on Iron, formed in 1861 by War Secretary Lord Herbert for the continued research into naval armour. Among its members was Sir William Fairbairn, a noted civil and structural engineer who had also built over 80 iron vessels before retiring from shipbuilding. Other members included metallurgist John Percy, civil engineer William Pole and representatives of the Royal Engineers, Royal Artillery and Royal Navy. This committee worked four years, between 1861 and 1865, during which time it formulated the best performing armor with the metallurgy as then known, suggested ways for improving its production and quality and helped develop more effective shot against ironclad vessels.For instance, two processes were used in constructing iron armor. In the first, hammering, large lumps of iron of scrap or puddled iron were heated to welding temperature and placed under heavy steel hammers. Repeated blows welded these lumps into one solid plate and shaped it to the required form and dimensions. Hammered iron plate was the armor used in the earliest ironclad vessels, including HMS Warrior. The second method, rolling, involved stacking iron lumps atop one another, heating them to welding temperature and passing them between two iron rollers to become one plate of the required size. Rolled iron was difficult to produce initially, as it required machinery of immense size and great power. However, when the Special Committee tested both types of plate in 1863, it found that rolled iron was superior to hammered due to greater uniformity in quality. The committee and iron manufacturers worked together on how to more easily produce rolled plate, which became standard use in warships beginning in 1865.The committee addressed the use of wooden backing with iron armor. Early European iron armour consisted of between four and five inches (roughly 10 to 13 cm) of wrought iron backed by between 18 and 36 inches (roughly one-half to one metre) of solid wood. After considerable testing, the committee found that wood prevented spalling, cushioned the shock of a hit from damaging the structure of the ship and distributed the force over a larger area, which prevented penetration. The drawback of using wood and iron was extreme weight. Experiments with reducing or eliminating wooden backing to save weight proved unsuccessful. The committee also tested steel as potential armor as its members felt that the harder the armor, the better it might deflect or resist shot. However, the steel being produced at that time proved too brittle to be effective. Iron, being softer, bent, dented and distorted but held together and remained an effective means of protection.Experiments were also carried out with laminated armour, but these did not lead to any improvements and single plates were preferred. Many ships made during the US Civil War used laminated armour but this was necessitated by lack of facilities for manufacturing single plates of proper thickness.Due to the ever increasing thickness of the armour, and the associated weight, proposals were made from an early date to faceharden the iron or weld steel plates to the front face of iron armour. Efforts to carry out these proposals failed for many reasons, primarily because the metallurgy at the time was not up to the task.By the mid-to-late 1870s, iron armour started to give way to steel armour, which promised to reduce the thickness, and therefore the weight, of the armour.

The Iron Jaw is a traditional aerial circus act.The act consists of a performer raised into the air by a cable, trapeze or other similar apparatus, supported only by a bit clamped between her teeth. Depending on the apparatus the bit is attached to, the performer can alternately swing in circles around the ring below or spin wildly in place, controlling speed by alternately extending her arms and legs out or bringing them in close to her body to speed up (known as the conservation of angular momentum principle).The act is frequently referred to as the Human Butterfly due to the removable wings which traditionally adorn the performer's costume.

Iron oxides are chemical compounds composed of iron and oxygen. All together, there are sixteen known iron oxides and oxyhydroxides.Iron oxides and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, in thermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide.

Genes involved in iron metabolism disorders include HFE and TFR2.Hepcidin is the master regulator of iron metabolism and, therefore, most genetic forms of iron overload can be thought of as relative hepcidin deficiency in one way or another[1]. For instance, a severe form of iron overload, juvenile hemochromatosis, is a result of severe hepcidin deficiency. The majority of cases are caused by mutations in the hemojuvelin gene (HJV or RGMc/repulsive guidance molecule c). The exceptions, people who have mutations in the gene for ferroportin, prove the rule: these people have plenty of hepcidin, but their cells lack the proper response to it. So, in people with ferroportin proteins that transport iron out of cells without responding to hepcidin's signals to stop, they have a deficiency in the action of hepcidin, if not in hepcidin itself.But the exact mechanisms of most of the various forms of adult hemochromatosis, which make up most of the genetic iron overload disorders, remain unsolved. So while researchers have been able to identify genetic mutations causing several adult variants of hemochromatosis, they now must turn their attention to the normal function of these mutated genes.These genes represent multiple steps along the pathway of iron regulation, from the body's ability to sense iron, to the body's ability to regulate uptake and storage. Working out the functions of each gene in this pathway will be an important tool for finding new methods of treating genetic disorders, as well as for understanding the basic workings of the pathway.So though many mysteries of iron metabolism remain, the discovery of hepcidin already allows a much better understanding of the nature of iron regulation, and makes researchers optimistic that many more breakthroughs in this field are soon to come.

Iron (Fe) deficiency is a plant disorder also known as "lime-induced chlorosis". It can be confused with manganese deficiency. A deficiency in the soil is rare but iron can be unavailable for absorption if soil pH is not between about 5 and 6.5. A common problem is excessive alkalinity of the soil (the pH is above 6.5). Also, iron deficiency can develop if the soil is too waterlogged or has been overfertilised.

Iron ore mining in Western Australia, in the financial year 2008-09, accounted for 47 percent of the total value of the state's resources, with a value of A$33.56 billion. The overall value of the mineral and petroleum industry in Western Australia was A$71.3 billion in 2008-09, a 19 percent increase compared to the previous financial year.Western Australia's iron ore output for 2011 was 474 million tonnes, 97% of Australian production.

The iron peak is a local maximum in the vicinity of Fe (Cr, Mn, Fe, Co and Ni) on the graph of the abundances of the chemical elements, as seen below.For elements lighter than iron on the periodic table, nuclear fusion releases energy while fission consumes it. For iron, and for all of the heavier elements, nuclear fusion consumes energy, but nuclear fission releases it. Chemical elements up to the iron peak are produced in ordinary stellar nucleosynthesis.

Another version of this chair was even more diabolical due to the addition of hundreds of sharp spikes which lined the back, seat, armrests and leg rests. The number of spikes ranged from 500 to 1,500.
