The Electron-Land Cup is a Go competition.
The Electron-Land Cup is sponsored by Korean Economic News, Baduk TV, and Cyber Kiwon. The format is lightning knockout. The tournament consists of 24 players split into 3 groups of 8. The first group is the Blue Dragon (Cheong-ryong), for players who are 25 or under. The White Tiger (Baekho), for players who are from 26 to 50 years old. The last group is the Phoenix (Bonghwang) for players 50 or above. The komidashi is 6.5 points, and the time limits are 20 minutes for each player plus byo-yomi. The final is a best of three match. The winner's purse is 40 million SKW/$42,500.

Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in the electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of Biochemistry and Molecular Biology (IUBMB), cytochromes a, cytochromes b, cytochromes c and cytochrome d.
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate recurrence of their properties is evident. The table is divided into four roughly rectangular areas called blocks. Elements in the same group tend to show similar chemical characteristics.
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample. The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the intensity of the detected signal to produce an image. In the most common SEM mode, secondary electrons emitted by atoms excited by the electron beam are detected using a secondary electron detector. The number of secondary electrons that can be detected, and thus the signal intensity, depends, among other things, on specimen topography. Some SEMs can achieve resolutions better than 1 nanometer.
The Davis Cup is the premier international team event in men's tennis. It is organised by the International Tennis Federation (ITF) and contested annually between teams from over 150 competing countries, making it the world's largest annual team sporting competition. It is described by the organisers as the "World Cup of Tennis" and the winners are referred to as the world champions. The competition began in 1900 as a challenge between Great Britain and the United States. By 2023 155 nations entered teams into the competition.
In organic chemistry, aromaticity is a chemical property describing the way in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibits a stabilization stronger than would be expected by the stabilization of conjugation alone. The earliest use of the term was in an article by August Wilhelm Hofmann in 1855. There is no general relationship between aromaticity as a chemical property and the olfactory properties of such compounds.
Lunar Lander is a genre of video games loosely based on the 1969 landing of the Apollo Lunar Module on the Moon. In Lunar Lander games, players control a spacecraft as it falls toward the surface of the Moon or other astronomical body, using thrusters to slow the ship's descent and control its horizontal motion to reach a safe landing area. Crashing into obstacles, hitting the surface at too high a velocity, or running out of fuel all result in failure. In some games in the genre, the ship's orientation must be adjusted as well as its horizontal and vertical velocities.
In chemistry and physics, valence electrons are electrons in the outermost shell of an atom, and that can participate in the formation of a chemical bond if the outermost shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each contributing one valence electron.
Olympique Lyonnais, commonly referred to as simply Lyon or OL, is a French professional football club based in Lyon, Auvergne-Rhône-Alpes. With origins dating back to 1899, they were founded in 1950 and provisionally compete in France's second highest football division, Ligue 2. The club won its first Ligue 1 championship in 2002, beginning a national record-setting streak of seven successive titles. Lyon has also won eight Trophées des Champions, five Coupes de France, and three Ligue 2 titles.
The Billie Jean King Cup is the premier international team competition in women's tennis, launched as the Federation Cup in 1963 to celebrate the 50th anniversary of the International Tennis Federation (ITF). The name was changed to the Fed Cup in 1995, and changed again in September 2020 in honor of former World No. 1 Billie Jean King. The Billie Jean King Cup is the world's largest annual women's international team sports competition in terms of the number of nations that compete. The current chair is Katrina Adams.
A Faraday cup is a metal (conductive) cup designed to catch charged particles. The resulting current can be measured and used to determine the number of ions or electrons hitting the cup. The Faraday cup was named after Michael Faraday who first theorized ions around 1830.
The Davisson–Germer experiment was a 1923–1927 experiment by Clinton Davisson and Lester Germer at Western Electric, in which electrons, scattered by the surface of a crystal of nickel metal, displayed a diffraction pattern. This confirmed the hypothesis, advanced by Louis de Broglie in 1924, of wave-particle duality, and also the wave mechanics approach of the Schrödinger equation. It was an experimental milestone in the creation of quantum mechanics.
Calcio Lecco, or simply Lecco, is a football team based in Lecco, Lombardy, Italy. Founded in 1912, the club plays in Serie C Group A.
At the end of each FIFA World Cup final tournament, several awards are presented to the players and teams who have distinguished themselves in various aspects of the game.
In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes.
A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term seems to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block.
Electrophilic aromatic substitution (SEAr) is an organic reaction in which an atom that is attached to an aromatic system is replaced by an electrophile. Some of the most important electrophilic aromatic substitutions are aromatic nitration, aromatic halogenation, aromatic sulfonation, alkylation Friedel–Crafts reaction and acylation Friedel–Crafts reaction.
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. Electron services the commercial small satellite launch market. It's the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron.
Explorer 47, was a NASA satellite launched as part of the Explorers program. Explorer 47 was launched on 23 September 1972 from Cape Canaveral, Florida, with a Thor-Delta 1604. Explorer 47 was the ninth overall launch of the Interplanetary Monitoring Platform series, but received the launch designation "IMP-7" because two previous "Anchored IMP" flights had used "AIMP" instead.
Explorer 50, also known as IMP-J or IMP-8, was a NASA satellite launched to study the magnetosphere. It was the eighth and last in a series of the Interplanetary Monitoring Platform.
