Strathclyde Partnership For Transport
Strathclyde Partnership for Transport (SPT) is a regional transport partnership for the Strathclyde area of western Scotland. It is responsible for planning and coordinating regional transport, especially the public transport system in the area, including responsibility for operating the Glasgow Subway, the third-oldest in the world. History The principal predecessor to SPT was the Greater Glasgow Passenger Transport Executive (GGPTE) set up in 1972 to take over the Glasgow Corporation's public transport functions and to co-ordinate public transport in the Clyde Valley. In 1983 it was replaced by the Strathclyde Passenger Transport Executive (SPTE), under the overall direction of Strathclyde Regional Council. Section 40 of the Local Government etc. (Scotland) Act 1994 created a new statutory corporation, the Strathclyde Passenger Transport Authority (SPTA), which took over "''all of the functions, staff, property, rights, liabilities and obligations of Strathclyde Regional ...

Symmetry-protected Topological Order
Symmetry-protected topological (SPT) order is a kind of order in absolute zero, zero-temperature quantum-mechanical states of matter that have a symmetry and a finite energy gap. To derive the results in a most-invariant way, renormalization group, renormalization group methods are used (leading to equivalence classes corresponding to certain fixed points). The SPT order has the following defining properties: (a) ''distinct SPT states with a given symmetry cannot be smoothly deformed into each other without a phase transition, if the deformation preserves the symmetry''. (b) ''however, they all can be smoothly deformed into the same trivial product state without a phase transition, if the symmetry is broken during the deformation''. The above definition works for both bosonic systems and fermionic systems, which leads to the notions of bosonic SPT order and fermionic SPT order. Using the notion of quantum entanglement, we can say that SPT states are short-range entanglement, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pole Telescope
The South Pole Telescope (SPT) is a diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica. The telescope is designed for observations in the microwave, millimeter-wave, and submillimeter-wave regions of the electromagnetic spectrum, with the particular design goal of measuring the faint, diffuse emission from the cosmic microwave background (CMB). Key results include a wide and deep survey of discovering hundreds of clusters of galaxies using the Sunyaev–Zel'dovich effect, a sensitive 5 arcminute CMB power spectrum survey, and the first detection of B-mode polarized CMB. The first major survey with the SPT—designed to find distant, massive, clusters of galaxies through their interaction with the CMB, with the goal of constraining the dark energy equation of state—was completed in October 2011. In early 2012, a new camera (SPTpol) was installed on the SPT with even greater sensitivity and the capability to measure the polarization of incoming ...

Septic Pelvic Thrombophlebitis
Septic pelvic thrombophlebitis (SPT), also known as suppurative pelvic thrombophlebitis, is a rare postpartum complication which consists of a persistent postpartum fever that is not responsive to broad-spectrum antibiotics, in which pelvic infection leads to infection of the vein wall and intimal damage leading to thrombogenesis in the ovarian veins (left or right, although right is more common due to dextroversion of the uterus). The thrombus is then invaded by microorganisms. Ascending infections cause 99% of postpartum SPT. Septic pelvis thrombophlembitis is a cause of post-operative fever from untreated postpartum endometritis or parametritis. After 48 hours of unresolved postpartum endometritis (notably 48 hours of fever that is unaffected by antibiotics), SPT is assumed until proven otherwise (with pelvic radiography). Imaging studies can be helpful in patient refractory to broad-spectrum parenteral antibiotics to look for abscess, retained products, or septic pelvic thro ...

Social Penetration Theory
The social penetration theory (SPT) proposes that interpersonal communication moves from relatively shallow, non-intimate levels to deeper, more Intimate relationship, intimate ones as relationships. The theory was formulated by psychologists Irwin Altman of the University of Utah and Dalmas Taylor of the University of Delaware in 1973 to understand the development of relationships between individuals. Altman and Taylor noted that relationships "involve different levels of intimacy of exchange or degree of social penetration". Thinking about how relationships typically become closer, modern researchers are using SPT to understand how people connect and build relationships online, like on social media. This idea helps researchers consider the ethical questions and problems that come up when people share personal details and try to keep things private when they interact online. SPT posits that relationship development progresses through stages characterized by increasing breadth and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Powered Tracer
, sometimes translated as ''Blue Meteor SPT Layzner'', is a science fiction anime series produced by Sunrise between 1985 and 1986. It was originally written by Tsunehisa Itō with Ryōsuke Takahashi as series' director. The series focuses on an alien invasion and subsequent totalitarian world occupation and resistance in a timeline where the Cold War continues. Premise The story takes place in the year 1996, where humanity is advanced enough to develop long-range space travel, as well as bases on both the Moon and Mars. However, Cold War tensions between the United States and the Soviet Union have not ended; rather, they have escalated as both sides continue to militarize space, and the shadow of nuclear conflict looms over humanity both on and off Earth. Meanwhile, on Mars, an exchange program created by the United Nations to promote peace and understanding is about to begin; the "Cosmic Culture Club"—consisting of 16 members, as well as their instructor Elizabeth— ...

Stationary Plasma Thruster
In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall effect, Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. The Hall-effect thruster is classed as a moderate specific impulse (1,600s) space propulsion technology and has benefited from considerable theoretical and experimental research since the 1960s. Hall thrusters operate on a variety of propellants, the most common being xenon and krypton. Other propellants of interest include argon, bismuth, iodine, magnesium, zinc and adamantane. Hall thrusters are able to accelerate their exhaust to effective exhaust velocity, speeds between 10 and 80 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
