• Steam car — An archaic technical term used at the dawn of the industrial era to designate a self-propelled vehicle operating on a steam engine, representing the direct predecessor of the modern internal combustion automobile. These massive vehicles, equipped with large pressure boilers, played a vital role in the development of heavy land transport and agricultural mechanization in the 19th century, before being completely replaced due to low thermal efficiency and the long startup times required to boil water.
• Axis — A term with double structural valence; in archaic or regional language it represents a phonetic variant for 'ax' (central rotating shaft), while in a modern technological context it is used as an international acronym for Attitude Control System. Its Romanian lexicographical definition focuses on the longitudinal mechanical element that supports or transmits the circular motion of components within a mechanism.
• Actinophage — A bacterial virus (bacteriophage) structurally specialized in infecting and destroying bacteria of the order Actinomycetales (actinomycetes). These viruses play an essential ecological and industrial role, being utilized in genetic research or bacterial infection control, but can also pose a structural threat in the biotechnology industry if they jeopardize bacterial cultures used for antibiotic production.
• Aquaplane — A rectangular or aerodynamic board made of wood, plastic, or composite material, towed by a fast motorboat, upon which an athlete stands to glide across the water surface; also, in aviation, it can designate a structural hydro-surface designed for seaplanes. This device utilizes hydrodynamic lift force to maintain balance and speed on the water surface.
• Adopter — An individual who adopts or intends to adopt a child, legally acquiring the rights and obligations of a biological parent through a court order. In organizational sociology and marketing, the term refers to an economic agent or user who accepts, internalizes, and implements a technology, work method, or conceptual trend in a market.
• Flying car — A hybrid experimental or conceptual vehicle designed to operate both as an automobile on public roads and as an aircraft on airways, utilizing foldable or retractable wings and a mixed propulsion system. This advanced technological concept aims to relieve terrestrial traffic congestion by integrating daily commuting into controlled airspace.
• Aerodrome craft — An archaic, rare, or conceptual technical term used to describe an experimental heavier-than-air aircraft, an early prototype of a self-propelled airplane, or a covered dome-shaped structure designed for sheltering and protecting flight machines inside an airfield.
• Aerophotographic — Relating to aerophotography, concerning aerial photography; executed through airborne photography from airplanes, helicopters, or drones. It refers to optical equipment, techniques, flight crafts, or mapping materials used in the process of capturing high-altitude images for military, geodetic, or journalistic purposes.
• Wind turbine — A complex technical installation (wind turbine) consisting of a bladed rotor, a speed multiplier, and an electrical generator, structurally designed to capture the kinetic energy of the wind and transform it directly into useful electrical energy. It represents the fundamental pillar of modern wind power plants destined for clean and renewable energy production.
• Air ionization — A natural or artificial process through which gas molecules within the air composition are transformed into air ions (electrically charged); in medicine and balneology, it represents the therapeutic use of air controlledly enriched with ions (especially negative ones) to relieve respiratory, cardiovascular, or stress conditions.
• Aeronautics — The science, technology, and collective industries dealing with the design, construction, testing, operation, and navigation of aircraft within Earth's atmosphere. The field encompasses complex disciplines such as aerodynamics, aerospace structures, propulsion, and avionics systems, aiming to optimize the safe movement of vehicles lighter or heavier than air.
• Aerosolization — The act of aerosolizing and its result; a physical, mechanical, or experimental process through which a liquid or solid substance is transformed into microscopic particles suspended in air or a gaseous medium. In medicine, it represents the fundamental operating technique of nebulizers to allow efficient drug delivery directly into the pulmonary alveoli.
• Aerospace — Belonging or relating simultaneously to Earth's atmosphere and the outer space beyond it, or to the design and construction of vehicles intended for navigation in both environments. This term describes an extremely complex industrial and scientific branch, structurally encompassing aerodynamic research, rocket engineering, satellite flight, and extra-atmospheric navigation systems.
• Aerotechnical — Belonging to aviation technology or relating to the construction, operation, and maintenance of aircraft; concerning aerotechnics. The term describes industrial mechanical processes, aerodynamic design standards, or precision devices specially designed for the civil and military aeronautical environment.
• Aerotechnics — The science or collective applied techniques studying the design, construction, testing, and maintenance of aircraft, as well as the functioning of mechanical and aerodynamic systems in aviation. This structural industrial field includes turbine manufacturing, load-bearing structure assembly, and gas flow optimization within engines under strict safety conditions.
• Aerothermal — Relating to thermal phenomena occurring in the air or under the influence of air currents; concerning heat transformations within gaseous media. In modern technology, it describes advanced systems or heat pumps (air-to-water or air-to-air) that extract the thermal energy naturally stored in the outdoor air to provide building climate control.
• Aerial vehicle — Any vehicle, complex technical apparatus, or aircraft structurally designed to navigate, sustain itself, and perform transport operations within Earth's atmosphere. This vast category encompasses both lighter-than-air craft (balloons, airships) and heavier-than-air craft (planes, helicopters, drones, air-cushion vehicles).
• Agfacolor — A historical commercial name assigned to a series of color photographic technologies and materials developed by the German company Agfa, based on the structure of chromatic film with substantive color couplers. Originally launched in 1936 as Agfacolor Neu, this structural process revolutionized the global film and photography industry by simplifying the processing of color films.
• Agoda — A major global online travel agency and tech platform specializing in hotel accommodations, flights, airport transfers, and vacation packages; originally founded in Thailand and later acquired by Booking Holdings Inc., it is highly recognized for its competitive pricing algorithms focused on the Asia-Pacific market.
• Agro-energy — Energy produced, extracted, or utilized directly within the agricultural sector, combining agronomic practices with renewable energy technologies. This includes biomass, biofuels, and biogas production from livestock waste, as well as the implementation of agrivoltaic systems, where agricultural crops and solar panels coexist on the same land.
