Ethernet Passive Optical Network
Ethernet in the first mile (EFM) refers to using one of the Ethernet family of computer network technologies between a telecommunications company and a customer's premises. From the customer's point of view, it is their first mile, although from the access network's point of view it is known as the last mile. A working group of the Institute of Electrical and Electronics Engineers (IEEE) produced the standards known as IEEE 802.3ah-2004, which were later included in the overall standard IEEE 802.3-2008. Although it is often used for businesses, it can also be known as Ethernet to the home (ETTH). One family of standards known as Ethernet passive optical network (EPON) uses a passive optical network. History With wide, metro, and local area networks using various forms of Ethernet, the goal was to eliminate non-native transport such as Ethernet over Asynchronous Transfer Mode (ATM) from access networks. One early effort was the EtherLoop technology invented at Nortel Networks ...

United Panhellenic Organization Of Youth
The United Panhellenic Organization of Youth, abbreviated EPON ( el, Ενιαία Πανελλαδική Οργάνωση Νέων (ΕΠΟΝ)), was a Greek resistance organization that was active during the Axis Occupation of Greece in World War II. EPON was the youth wing of the National Liberation Front (EAM) organization, and was established on 23 February 1943 after the merger of ten earlier political and resistance youth organizations. Along with EAM and its other affiliates, EPON was dissolved judicially at the beginning of the Greek Civil War but continued to operate illegally until 1958. See also * Young Communist League of Greece Young Communist League of Greece ( el, Oμοσπονδία Kομμουνιστικών Nεολαιών Eλλάδας; OKNE) was the youth wing of the Communist Party of Greece. OKNE was founded on November 28, 1922. The journal ''I Neolaia'' (Η � ... References {{DEFAULTSORT:United Panhellenic Organization Of Youth Greek Resistance ...

Epoxy
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called ''epoxy''. The IUPAC name for an epoxide group is an oxirane. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, composites, use in ...

Electron Microscope
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50  pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200  nm resolution and useful magnifications below 2000×. Electron microscopes use shaped magnetic fields to form electron optical lens systems that are analogous to the glass lenses of an optical light microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, ...
