Akai AX60
The AX60 is a polyphonic analogue keyboard synthesizer manufactured by Akai Professional in the mid-1980s. It was Akai's answer to the popular Roland Juno series synthesizers. The AX60 uses voltage-controlled analogue oscillators and filter circuitry based on the Curtis Electronics CEM 3394 integrated circuit.

List of Thor and Delta Launches (1970–79)
Between 1970 and 1979, there were 117 Thor missiles launched, of which 108 were successful, giving a 92.3% success rate. NASA used it to launch its own satellites, as well as to launch satellites for foreign governments and companies.

Nanotechnology in Natural Cosmetics
Nanotechnology is a comparatively modern field in the cosmetic industry. Presently, nanotechnology is indeed important as a platform for creating science-based alternatives for advanced therapeutics and cosmetics, resolving antiaging challenges, and enhancing well-being. Nanotechnology is described as an investigation of substances on a molecular and atomic scale. Cosmeceuticals based on nanotechnology offer the benefits of product differentiation, improved bioavailability, and prolonged effects of active ingredients.

EM-2 Rifle
The EM-2, also known as Rifle No.9 Mk1 or Janson rifle, was an experimental United Kingdom assault rifle. It was briefly adopted by British forces in 1951, but the decision was overturned very shortly thereafter by Winston Churchill's incoming government in an effort to secure NATO standardisation of small arms and ammunition. An innovative weapon with the compact bullpup layout and an optical sight, it used one of the early intermediate cartridges (a concept introduced by the Germans with the 7.92×33mm Kurz) as a result of combat experience and German advances in weapons design during World War II. It used the experimental, intermediate powered, but highly efficient .280 British round, which was designed to replace the venerable .303 round and Lee–Enfield rifle variants which had served since before the turn of the 20th century. The United States claimed the .280 British round was too weak for use in rifles and machine guns, and instead favored the much more powerful 7.62×51mm NATO round. As the EM-2 could not be easily adapted to the longer and more powerful round, it faded from use. However, the bullpup layout for a British service rifle was finally adopted some years later in form of the SA80 assault rifle, the EM-2's spiritual successor, which remains in service today.

Lockheed XF-104
The Lockheed XF-104 was a single-engine, high-performance, supersonic interceptor prototype for a United States Air Force (USAF) series of lightweight and simple fighters. Only two aircraft were built; one aircraft was used primarily for aerodynamic research and the other served as an armament testbed, both aircraft being destroyed in accidents during testing. The XF-104s were forerunners of over 2,500 production Lockheed F-104 Starfighters. During the Korean War, USAF fighter pilots were outclassed by MiG-equipped Soviet pilots. Lockheed engineers, led by Kelly Johnson, designed and submitted a novel design to the Air Force, notable for its sleekness, particularly its thin wings and missile-shaped fuselage, as well as a novel pilot ejection system. Flight testing of the XF-104s began with the first flight in March 1954, encountering several problems, some of which were resolved; however, performance of the XF-104 proved better than estimates and despite both prototypes being lost through accidents, the USAF ordered 17 service-test/pre-production YF-104As. Production Starfighters proved popular, both with the USAF and internationally, serving with a number of countries, including Jordan, Turkey, and Japan.

Friction Behavior of Rough Surfaces on Contact Mechanics
Contact and friction are closely related to the engineering industry, especially in the technologies associated with rolling bearing, wheel–rail control, head–disk interaction and so on. Therefore, which factors are related to the contact mechanical properties of solid surface and how to design and control the interface friction coefficient are hot issues in scientific research and engineering practice. In fact, the contact behavior and friction properties are closely related to the microstructure of the contact surface. Based on the accurate characterizations of the surface topography, the corresponding research can start from the local contact model, investigating the contact and friction relationships of each contact asperity of the rough surface, and finally accurately predicting the contact relationships and friction performances of the interfaces.

Maritime Express
The Maritime Express was a Canada passenger train. When it was launched on the first of March, 1898, it was the flagship of the Intercolonial Railway (ICR) between Halifax, Nova Scotia and Montreal , Quebec. The train was operated by the Canadian National Railway (CNR) from 1919 until 1964, when it was reduced to a regional service and its name retired.
