Takanoyama Shuntarō (born 21 February 1983 as Pavel Bojar) is a former sumo wrestler from Prague, Czech Republic.
 He is the first man from the Czech Republic to join the professional sport in Japan.
 He reached the third highest "makushita" division in 2004, but due to his light weight he had difficulty in regularly beating his opponents, despite his skill.
 However, in May 2011 he finally earned promotion to the "sekitori" ranks.
 After becoming only the third new "sekitori" since 1958 to pass through "jūryō" division in just one tournament, he made his debut in the top "makuuchi" division in September 2011.
 He retired on 24 July 2014.
A cardboard record was a type of cheaply made phonograph record made of plastic-coated thin paperboard.
 These discs were usually small, had poor audio quality compared to vinyl or acetate discs, and were often only marginally playable due to their light weight, slick surface, and tendency to warp like a taco shell.
 Playability could be improved by placing a coin between the lock groove and the spindle hole to add weight and stability.
 These records are distinct from both flexi discs, which are sturdier, and from many of the old home-recording discs since cardboard discs were mass-produced for a specific purpose.
Al-Ca composite is a high-conductivity, high-strength, lightweight composite consisting of sub-micron-diameter pure calcium metal filaments embedded inside a pure aluminium metal matrix.
 The material is still in the development phase, but it has potential use as an overhead high-voltage power transmission conductor.
 It could also be used wherever an exceptionally light, high-strength conductor is needed.
 Its physical properties make it especially well-suited for DC transmission.
 Compared with conventional conductors such as aluminium-conductor steel-reinforced cable (ACSR), all aluminium alloy conductors (AAAC), aluminium conductor alloy reinforced (ACAR), aluminium conductor composite reinforced ACCR and ACCC conductor that conduct AC current well and DC current somewhat less well (due to the skin effect), Al-Ca conductor is essentially a single uniform material with high DC conductivity, allowing the core strands and the outer strands of a conductor cable to all be the same wire type.
 This conductor is inherently strong so that there is no need for a strong (usually poorly conductive) core to support its own weight as is done in conventional conductors.
 This eliminates the "bird caging", spooling, and thermal fatigue problems caused by thermal expansion coefficient mismatch between the core and outer strands.
 The Al-Ca phase interfaces strengthen the composite substantially, but do not have a noticeable effect on restricting the mean free path of electrons, which gives the composite both high strength and high conductivity, a combination that is normally difficult to achieve with both pure metals and alloys.
 The high strength and light weight could reduce the number of towers needed per kilometer for long distance transmission lines.
 Since towers and their foundations often account for 50% of a powerline's construction cost, building fewer towers would save a substantial fraction of total construction costs.
 The high strength also could increase transmission reliability in wind/ice loading situations.
 The high conductivity has the potential to reduce Ohmic losses.
Maximum Fighting Championship is a Canadian mixed martial arts (MMA) promotion based in Edmonton, Alberta.
 MFC’s former home, in Canada, is the River Cree Resort and Casino in Enoch, Alberta, located just outside Edmonton, Alberta but has also held events at the Edmonton Expo Centre.
 MFC events are broadcast on The Fight Network, AXS TV (formerly HDnet) in North America and most recently TSN2.
 MFC is known to be the biggest MMA promotion in Canada and one of the top MMA shows in the World.
 MFC has notable Canadian fighters, such as Ryan Jimmo, Graham Spencer, Tom Watson and Douglas Lima, plus MMA veterans, such as Jason MacDonald, Thales Leites, Jay Silva, Trevor Prangley, and Paul Daley.
MNOS (meaning "MobilNaya Operatsionnaya Sistema" (МобильНая Операционная Система, МНОС), or "Portable Operating System") was a Unix-like operating system developed in the Soviet Union.
 It was derived from Version 6 Unix and consequently heavily modified to incorporate many features of BSD Unix.
 From 1983 until 1986 it enjoyed significant popularity in the USSR and other Eastern Bloc countries, due to its light weight and better performance than that of Version 7 Unix (and later BSD Unix-based) alternatives.
Trevor Prangley (born 24 August 1972) is a South African mixed martial artist.
 He has fought in the UFC, Strikeforce, Bellator, Dream, King of the Cage, MFC, the SFL, Shark Fights, and Bodog Fight.
 He competed in the Middleweight and Light Heavyweight divisions.
 He was the former King of the Cage Light Heavyweight Champion, the former Shark Fights Light Heavyweight Champion, and the former MFC Light Heavyweight Champion.
The Wrightspeed X1 is a one-off Ariel Atom heavily modified to use an all-electric powertrain.
 The Atom was chosen for its light weight and efficient design.
 The electric motor and inverter are sourced from AC Propulsion, makers of the TZero concept car, while the batteries are low weight, high energy density lithium ion provided from A123 Systems.
 As with the "Atom" the transmission is a Honda unit, but stripped of its shifting mechanism and other parts to provide only the second gear speed, allowed by the wide speed and torque range available from the electric motor.
The middleweight division in mixed martial arts refers to different weight classes:
The Medium Tank M7 was originally conceived as an up-gunned replacement for the Light Tank M3/M5.
 The project was supposed to mount the same 75mm armament as the M4 Sherman while retaining the light weight and maneuverability of the M3 Stuart; however, during development the weight of the prototype surpassed the US Army's standard for light tanks and crossed into the medium category and was renamed.
 The M7 had significantly less armor than the M4 Sherman, boasted no greater firepower, and held only a slight advantage in top speed.
 For these reasons, and because the M4 was already battle-tested and in full production, the M7 was put aside shortly after completing trials.
Terao Tsunefumi (寺尾 常史 , born February 2, 1963 as Yoshifumi Fukuzono 福薗 好文) is a Japanese former sumo wrestler.
 He was born in Tokyo, but brought up in Kajiki, Aira District, Kagoshima, Japan.
 He fought out of Izutsu stable.
 The highest rank he reached was "sekiwake."
 Despite his relatively light weight he had an extremely long career, spanning 23 years from 1979 until 2002, and was known as the "iron man" of sumo.
 He is now the head coach of Shikoroyama stable.
