Acid Facility
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Info ...

Tecumseh Professional Associates
Tecumseh ( ; October 5, 1813) was a Shawnee chief and warrior who promoted resistance to the expansion of the United States onto Native American lands. A persuasive orator, Tecumseh traveled widely, forming a Native American confederacy and promoting intertribal unity. Even though his efforts to unite Native Americans ended with his death in the War of 1812, he became an iconic folk hero in American, Indigenous, and Canadian popular history. Tecumseh was born in what is now Ohio, at a time when the far-flung Shawnees were reuniting in their Ohio Country homeland. During his childhood, the Shawnees lost territory to the expanding American colonies in a series of border conflicts. Tecumseh's father was killed in battle against American colonists in 1774. Tecumseh was thereafter mentored by his older brother Cheeseekau, a noted war chief who died fighting Americans in 1792. As a young war leader, Tecumseh joined Shawnee Chief Blue Jacket's armed struggle against further Amer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonium Nitrate
Ammonium nitrate is a chemical compound with the chemical formula . It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.Karl-Heinz Zapp "Ammonium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'' 2012, Wiley-VCH, Weinheim. Global production was estimated at 21.6 million tonnes in 2017. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Oleum Production
Oleum (Latin ''oleum'', meaning oil), or fuming sulfuric acid, is a term referring to solutions of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid). Oleum is identified by the CAS number 8014-95-7 (EC/List number: 616-954-1 ECHA InfoCard: 100.116.872. Oleums can be described by the formula ''y''SO3·H2O where ''y'' is the total molar mass of sulfur trioxide content. The value of ''y'' can be varied, to include different oleums. They can also be described by the formula H2SO4·''x''SO3 where ''x'' is now defined as the molar free sulfur trioxide content. Oleum is generally assessed according to the free SO3 content by mass. It can also be expressed as a percentage of sulfuric acid strength; for oleum concentrations, that would be over 100%. For example, 10% oleum can also be expressed as H2SO4·''0.13611''SO3, ''1.13611''SO3·H2O or 102.25% sulfuric acid. The conversion between % acid and % ...
