Pes (unit)
The ancient Roman units of measurement were primarily founded on the Hellenic system, which in turn was influenced by the Egyptian system and the Mesopotamian system. The Roman units were comparatively consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' or Roman foot (plural: ''pedes''). Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IP Multimedia Subsystem
The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a standardised architectural framework for delivering IP multimedia services. Historically, mobile phones have provided voice call services over a circuit-switched-style network, rather than strictly over an IP packet-switched network. Alternative methods of delivering voice (VoIP) or other multimedia services have become available on smartphones, but they have not become standardized across the industry. IMS is an architectural framework that provides such standardization. IMS was originally designed by the wireless standards body 3rd Generation Partnership Project (3GPP), as a part of the vision for evolving mobile networks beyond GSM. Its original formulation (3GPP Rel-5) represented an approach for delivering Internet services over GPRS. This vision was later updated by 3GPP, 3GPP2 and ETSI TISPAN by requiring support of networks other than GPRS, such as Wireless LAN, CDMA2000 and fixed lines. IM ...

Potential Energy Surface
A potential energy surface (PES) describes the energy of a system, especially a collection of atoms, in terms of certain parameters, normally the positions of the atoms. The surface might define the energy as a function of one or more coordinates; if there is only one coordinate, the surface is called a ''potential energy curve'' or energy profile. An example is the Morse/Long-range potential. It is helpful to use the analogy of a landscape: for a system with two degrees of freedom (e.g. two bond lengths), the value of the energy (analogy: the height of the land) is a function of two bond lengths (analogy: the coordinates of the position on the ground). The PES concept finds application in fields such as chemistry and physics, especially in the theoretical sub-branches of these subjects. It can be used to theoretically explore properties of structures composed of atoms, for example, finding the minimum energy shape of a molecule or computing the rates of a chemical reaction. ...

Polyethersulfone
Polysulfones are a family of high performance thermoplastics. These polymers are known for their toughness and stability at high temperatures. Technically used polysulfones contain an aryl- SO2-aryl subunit. Due to the high cost of raw materials and processing, polysulfones are used in specialty applications and often are a superior replacement for polycarbonates. Three polysulfones are used industrially: polysulfone (PSU), polyethersulfone (PES/PESU) and polyphenylene sulfone (PPSU). They can be used in the temperature range from -100 to +200 °C and are used for electrical equipment, in vehicle construction and medical technology. They are composed of para-linked aromatics, sulfonyl groups and ether groups and partly also alkyl groups. Polysulfones have outstanding resistance to heat and oxidation, hydrolysis resistance to aqueous and alkaline media and good electrical properties. Nomenclature The term "polysulfone" is normally used for polyarylethersulfones (PAES), si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poly(ethylene Succinate)
Poly(ethylene succinate) (PES) is an aliphatic synthetic polyester with a melting point from 103–106 °C. It is synthesized from dicarboxylic acids; either by ring-opening polymerization of succinic anhydride with ethylene oxide or by polycondensation of succinic acid and ethylene glycol. Thermophilic ''Bacillus'' sp. TT96 is found in soil and can degrade PES. Mesophilic PES degrading microorganisms were found in the ''Bacillus'' and ''Paenibacillus'' species; strain KT102; a relative of ''Bacillus pumilus'' was the most capable of degrading PES film. The fungal species NKCM1003 a type of ''Aspergillus clavatus ''Aspergillus clavatus'' is a species of fungus in the genus ''Aspergillus'' with conidia dimensions 3–4.5 x 2.5–4.5 μm. It is found in soil and animal manure. The fungus was first described scientifically in 1834 by the French mycologist ...'' also degrades PES film. The solubility of lithium salts (e.g. lithium perchlorate, LiClO4) in PES made it a good al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photoemission Spectroscopy
Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, refers to energy measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies of electrons in the substance. The term refers to various techniques, depending on whether the ionization energy is provided by X-ray, XUV or UV photons. Regardless of the incident photon beam, however, all photoelectron spectroscopy revolves around the general theme of surface analysis by measuring the ejected electrons. Types X-ray photoelectron spectroscopy (XPS) was developed by Kai Siegbahn starting in 1957 and is used to study the energy levels of atomic core electrons, primarily in solids. Siegbahn referred to the technique as "electron spectroscopy for chemical analysis" (ESCA), since the core levels have small chemical shifts depending on the chemical environment of the atom that is ionized, allowing chemical structure to be determined. Siegbahn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pallasite Eagle Station
The Eagle Station group (abbreviated PES - Pallasite Eagle Station) is a set of pallasite meteorite specimen that don't fit into any of the other defined pallasite groups. In meteorite classification five meteorites have to be found, so they can be defined as their own group. Currently only five Eagle Station type meteorites have been found, which is just enough for a separate group. Naming and history The Eagle Station group is named after the Eagle Station meteorite, the type specimen of the group. It is in turned named after Eagle Station, Carroll County Kentucky where it was found. Description The Eagle Station group has a composition similar to Main group pallasites. Diagnostic differences are that the olivine is richer in iron and calcium. The group also has a distinct oxygen isotope signature. The meteoric iron is similar to the IIF iron meteorites. This might indicate that Eagle station group and IIF formed close to each other in the solar nebula. Parent body The tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019 Philadelphia Energy Solutions Refinery Explosion
On June 21, 2019, the Philadelphia Energy Solutions refinery in Philadelphia, Pennsylvania was the place of an explosion and fire early morning, when a release of hydrocarbons and hydrofluoric acid in the refinery's alkylation unit caused a ground-hugging vapor cloud which rapidly ignited, leading to three separate explosions minutes apart from each other. The largest explosion sent a vessel fragment flying 2,000 feet across the Schuylkill River. Five employees sustained minor injuries, but there were ultimately no reported fatalities. The refinery announced it would shut down operations the same month, and filed for bankruptcy a month later. Background The Philadelphia Energy Solutions refinery is an oil refinery in Philadelphia, Pennsylvania comprising two separate refineries, the Girard Point and Point Breeze refineries. The last fire to occur at the facility was June 10. Fire, explosion, and worker response On the morning of June 21, 2019, the refinery reported that th ...

Solidarity Encounter Party
The Solidarity Encounter Party ( es, Partido Encuentro Solidario, PES) was a political party in Mexico. The party president was Hugo Eric Flores Cervantes. It was the functional replacement for the Social Encounter Party, a Christian-oriented, social conservative party which lost its registration after failing to attract sufficient vote share in the 2018 general election. History In 2018, the Social Encounter Party, in its second federal election, ran as part of the ''Juntos Haremos Historia'' alliance with the National Regeneration Movement (MORENA) and Labor Party (PT). However, despite the alliance electing the winning presidential candidate—Andrés Manuel López Obrador—and the PES winning 35 seats in the Chamber of Deputies and seven in the Senate, its standalone performance was poor. The PES itself failed to attract three percent of the vote in the elections for president, federal deputies, and senators, which under Mexican law prompted the loss of its federal re ...

Social Encounter Party
Social Encounter Party ( es, Partido Encuentro Social, PES) was a Mexican conservative political party established on the national level in 2014 and dissolved in 2018. It was part of the coalition ''Juntos Haremos Historia'' with the National Regeneration Movement and Mexico's Labor Party for the 2018 Mexican election. It preceded the Solidarity Encounter Party, established as its replacement in 2019 and granted national party status in 2020. History The Social Encounter Party was founded in 2006 by Dr. Hugo Eric Flores Cervantes, a pastor of a Neo-Pentecostal church that supported Felipe Calderón in the 2006 presidential election. It had previously been a "national political grouping", which does not receive public funding. The party made many of its early successes in the state of Baja California. In 2007, it supported the successful candidacy of José Guadalupe Osuna Millán of the PAN, but in 2013, it allied with the PRI in Baja California instead, which led it to ele ...
