  2. Fold and thrust belt - Wikipedia

    en.wikipedia.org/wiki/Fold_and_thrust_belt

    Modelling of a fold and thrust belt in a sand box A fold and thrust belt (FTB) is a series of mountainous foothills adjacent to an orogenic belt , which forms due to contractional tectonics . Fold and thrust belts commonly form in the forelands adjacent to major orogens as deformation propagates outwards.

  3. Spot welding - Wikipedia

    en.wikipedia.org/wiki/Spot_welding

    Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a large amount of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). [2]

  4. Organic radical battery - Wikipedia

    en.wikipedia.org/wiki/Organic_radical_battery

    Since this half-reaction is not readily reversible as the half-reaction at the positive electrode, several research groups have steered away from using pure organic radical batteries and instead use metal/ORB hybrid batteries usually consist of a radical polymer cathode and the same anode found in rechargeable Li-ion batteries. [2] [3] [7]

  5. Ornithine transcarbamylase - Wikipedia

    en.wikipedia.org/wiki/Ornithine_transcarbamylase

    Ornithine transcarbamylase (OTC) (also called ornithine carbamoyltransferase) is an enzyme (EC 2.1.3.3) that catalyzes the reaction between carbamoyl phosphate (CP) and ornithine (Orn) to form citrulline (Cit) and phosphate (P i). There are two classes of OTC: anabolic and catabolic. This article focuses on anabolic OTC.

  6. O.R.B: Off-World Resource Base - Wikipedia

    en.wikipedia.org/wiki/O.R.B:_Off-World_Resource_Base

    As with most strategy games, the object of O·R·B is to defeat the enemy forces by gathering resources to build an attack fleet. As the name of the game implies, this is done by locating resource-bearing asteroids which must be mined to finance construction of new units.

  7. Oriented FAST and rotated BRIEF - Wikipedia

    en.wikipedia.org/wiki/Oriented_FAST_and_rotated...

    Oriented FAST and rotated BRIEF (ORB) is a fast robust local feature detector, first presented by Ethan Rublee et al. in 2011, [1] that can be used in computer vision tasks like object recognition or 3D reconstruction.

  8. Railgun - Wikipedia

    en.wikipedia.org/wiki/Railgun

    A railgun or rail gun, sometimes referred to as a rail cannon, is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high-velocity projectiles. The projectile normally does not contain explosives, instead relying on the projectile's high kinetic energy to inflict damage. [2]

  9. Thermal power station - Wikipedia

    en.wikipedia.org/wiki/Thermal_power_station

    Typically the cooling water causes the steam to condense at a temperature of about 25 °C (77 °F) and that creates an absolute pressure in the condenser of about 2–7 kPa (0.59–2.07 inHg), i.e. a vacuum of about −95 kPa (−28 inHg) relative to atmospheric pressure. The large decrease in volume that occurs when water vapor condenses to ...
