Sign about environment remediation, Gilberton, 2014 Gilberton has acid sulphate soil in naturally water-logged conditions. The lowering of the water table due to drainage work on the Pimpama River allows oxidisation of the iron sulfide to create sulphuric acid which can, in turn, enable the release of iron, aluminium and other heavy metals, doing damage to both the natural and built environment. Application of lime to neutralise low pH levels and the maintenance of broad shallow drains to reduce oxidisation are used to mitigate the problem.

30 April 1955 front cover of The Illustrated London News, issued shortly after the helmet's restoration After its discovery, the Emesa helmet underwent several unsuccessful restorations. The primary problem was the oxidisation of the iron core, which created blisters and cracks in the silver covering. Immediately after discovery, the helmet was sent to Paris for restoration by "MM. André père et fils"; only light work was carried out due to the hope that the Syrian climate would help slow the rate of oxidisation, and due to limited funds, but the helmet continued to deteriorate.

Fuente de los Azulejos rock formation Fuente de los Azulejos is an unusual rock formation on the island of Gran Canaria. The name literally means "fountain of tiles", because of the colour of the rocks resembling Portuguese tiles. These colours are caused by the process of oxidisation.

It was exhibited in the Tribuna in 1677 and attributed to Giorgione in 1709, as shown on a label on the back of the painting. It was then moved to the villa di Poggio a Caiano. After several subsequent moves, in 1798 it finally arrived back Uffizi. Oxidisation in the paint in the 19th century made attribution difficult.

Until the mid 19th century the paints were mineral or vegetable pigments. Ochres dominated but in finer interior work red and white lead, cinnabar, indigo, lapis lazuli, copper carbonate, vivid Indian yellow. The lead pigments were prone to oxidisation, blackening. From the mid 19th century, Germany’s industrial revolution created chemically synthesised pigments which were soon cheaply available.

Other organic materials such as leather, skin and textiles were treated similarly, by keeping them moist in tanks or sealed plastic containers. Bone and ivory was desalinated to prevent damage from salt crystallisation, as were glass, ceramic and stone. Iron, copper and copper alloy objects were kept moist in a sodium sesquicarbonate solution to prevent oxidisation and reaction with the chlorides that had penetrated the surface.

The eastern boundary is the mountain ridge containing Mount Yarrabah, Mount Murray Prior, Mount Gorton and May Peak. A satellite city urban development and construction of a bridge/tunnel linking Cairns City to East Trinity have been suggested in the past. As well as eco-tourism proposals. Parts of the land, water and environment in and around East Trinity have been subject to acid sulfate soil oxidisation.

In 1940, number 447's chimney required replacing due to wear and oxidisation. No Drummond spares were available, resulting in the application of a short stove-pipe chimney. When outshopped and pressed into service, there was a marked improvement in its steaming ability due to the improved draughting. The same enhancement was subsequently applied to all but one of the class as they went through Eastleigh works for overhaul.

In 1860, he established an experimental factory in Chiswick where he worked on oxidisation of linseed oil, for which he was granted a patent in 1860. He experimented with the oxidized oil as a replacement for rubber. He discovered that combining the oil with cork and colouring agents produced a useful material for floor covering, and in 1863 patented this new material. Walton called this new cloth "linoleum".

Passive components such as cables, connectors and antennas, are generally expected to be linear and therefore not liable to generate any intermodulation. However, especially at high power, a number of effects can lead to non-linearity through formation of a metal-semiconductor junction at what is supposed to be a metal-metal junction. These effects include corrosion, surface oxidisation, dirtiness, and simple failure to fully make mechanical contact. Some passive materials are intrinsically non-linear.

Maderisation is a process that involves the heating and oxidisation of a wine. The term is named after the process used in the production of Madeira wine, where it occurs while the wine is in cask. The resulting wine darkens in color and acquires a Sherry-like character. Outside Madeira wine, it is generally seen as a wine fault, but is desirable in the case of certain dessert wines where it occurs over the course of long bottle aging.

Nicolás Cabrera (1913-1989), was a Spanish physicist who did important work on the theories of crystal growth (specifically the Burton–Cabrera–Frank theory) and the oxidisation of metals. He was the son of another famous Spanish physicist Blas Cabrera and the father of American Physicist Blas Cabrera Navarro. He spent many years in exile during the Francoist State. He was Professor of the Department of physics in the University of Virginia, where he worked from 1952.

Whole window. Saint Thomas Becket window in Chartres Cathedral is a 1215-1225 stained-glass window in Chartres Cathedral, located behind a grille in the Confessors' Chapel, second chapel of the south ambulatory. 8.9 m high by 2.18 m wide, it was funded by the tanners' guild. The furthest left of five lancet windows in the chapel, it is difficult to view and is heavily corroded by glass oxidisation, which has made its left side especially hard to read.

This special manufacturing process also makes it possible to develop RED micro wire, for example RED Copper wire which is unique composite wire with a thin glass-coating and a soft copper core. Glass-coated wire had a huge impact on the LED industry by reducing the cost of interconnect components, specifically using Copper wire instead of Gold. Using the Adar- Bolotinsky process has made it possible to coat these wires with glass which protects it from oxidisation, increasing the shelf and operating life. these improvements have contributed to the current success of LED lighting.

Modern traditional climbs occasionally have fixed gear (pitons or bolts) in places where there are no opportunities to place adequate removable gear. It is considered bad style to install new protection bolts or pitons on existing climbs that can be completed without them. Many of the existing pitons, pegs and bolts from the first ascents of routes done many years ago are now considered to be in bad condition, having suffered from weathering. This is especially present on sea cliffs where the salt nature of the air has sped up the oxidisation to create rust and weaken the protection.

The cliffs to the east of the harbour are composed of Bridport Sand Formation and Inferior Oolite, while immediately to the west they are Frome Clay (Upper Fullers Earth) and Forest Marble. The Bridport Sands deposits were laid down in the Toarcian Age toward the end of the Early Jurassic; they are arranged horizontally with clear banding visible alternating between harder and softer material. The cliff's distinctive colour is a result of oxidisation of fine pyrite grains, resulting in limonite. The Frome Clay and Forest Marble of the West Cliff are younger and were formed in the Bathonian Age of the Middle Jurassic.

This opacification occurs as water seeps through the subsequent cracks, causing the formation of opaque syngenite and gypsum crystals that block light from filtering through the previously translucent glass (Rauch 2004, 3). As these crystals continue to grow, they pose an even greater danger to the glass, eventually breaking through the surface and dislodging the delicate paint layer, or even causing cracks (Rauch 2004, 4). Glass plates can also darken or cloud as the result of the oxidisation of certain metals, such as manganese, which was a common addition to late medieval glass (Rauch 2004, 4).

The integration of shallow microaglal oxidisation ponds was demonstrated by Golueke & Oswald in the 1960s. The widespread global implementation of these systems can be largely credited to Prof George Lai Chan (02 March 1924 Mauritius-08 October 2016 Mauritius) from ZERI.Zero Emissions Research & Initiatives ZERI Zero waste agriculture is now practiced in China (ecological farming), Columbia (integrated food & waste management systems) & Fiji (integrated farming systems), India (integrated biogas farming), South Africa (BEAT Coop & African Agroecological Biotechnology Initiative) and Mauritius. The Brazilian government has adopted integrated farming system as a major social technology for the uplifting of marginalized and subsistence farmers through coordination with TECPAR.

The red-brown colour (due to oxidisation of haematite) of the sandstone contrasts markedly with the grey-black latite, which displays spectacular columnar jointing elsewhere in the quarry. Isolated columns 5–5 meters in height stand adjacent to the coast between the north and south parts of the quarry; just to the north the sea wall exposes cross sections of the columns 1-2.5 metres in diameter, resulting in a "Giants Causeway" appearance. Petrographic descriptions of the latite emphasise its conspicuous porphyritic texture; large labradorite to andesine phenocrysts with minor clinopyroxene are set in a groundmass of feldspar microlites with interstital chlorite and iron oxide. The latite is commonly vesicular.

Mundic was used from the 1690s to describe a copper ore that began to be smelted at Bristol and elsewhere in southwestern Britain. Smelting was carried out in cupolas, that is reverberatory furnaces using mineral coal.J. Day, 'Copper, Zinc, and brass production' in J. Day & R. F. Tylesote (eds.), The industrial Revolution in Metals (Institute of Metals, London 1991), 141. For more details, see copper extraction. Mundic onceScience Direct: Very Low Frequency electromagnetic survey applied to mineralised zones on the north- western edge of Dartmoor, Devon referred to pyrite,Science Direct: ‘Mundic’-type problems: a building material catastrophe but has now adopted the wider meaning of concrete deterioration caused by oxidisation of pyrites within the aggregate (usually originating from mine waste).

In Mali, gunpowder tea is served in series of three, starting with the highest oxidisation or strongest, unsweetened tea, locally referred to as "strong like death", followed by a second serving, where the same tea leaves are boiled again with some sugar added ("pleasant as life"), and a third one, where the same tea leaves are boiled for the third time with yet more sugar added ("sweet as love"). Green tea is the central ingredient of a distinctly Malian custom, the "Grin", an informal social gathering that cuts across social and economic lines, starting in front of family compound gates in the afternoons and extending late into the night, and is widely popular in Bamako and other large urban areas. In the United States, 80% of tea is consumed as iced tea."Tea". Modern Marvels television (program).

These transmembrane transporters are localised both in the cytoplasmic membrane and in the MM, but in an inverted orientation; this configuration allows them to generate an efflux of Fe2+ ions at the cytoplasmic membrane, and an influx of this same ion at the MM. This step is strictly controlled by a cytochrome-dependent redox system, which is not yet fully explained and appears to be species-specific. During the final stage of the process, the magnetite crystal nucleation is by action of transmembrane proteins with acidic and basic domains. One of these proteins, called Mms6, has also been employed for the artificial synthesis of magnetite, where its presence allows the production of crystals homogeneous in shape and size. It is likely that many other proteins associated with the MM could be involved in other roles, such as generation of supersaturated concentrations of iron, maintenance of reducing conditions, oxidisation of iron, and partial reduction and dehydration of hydrated iron compounds.
