- Actinobiology — An interdisciplinary branch of biology dealing with the structural and physiological study of the effects produced by luminous, ultraviolet, x-ray, or nuclear radiation on living organisms and cellular macromolecules. Actinobiology analyzes both adaptive mechanisms or genetic mutations induced by radiant fluxes in the environment, as well as therapeutic applications or ecological risks determined by exposure to various sources of electromagnetic energy.
- Actinometry — A branch of meteorology and applied physics dealing with the structural and methodical study of measuring radiant energy intensity (specifically solar, atmospheric, and terrestrial radiation). Actinometry establishes experimental protocols, units of measurement, and operating principles for devices designed to evaluate thermal, chemical, or photochemical effects caused by short electromagnetic waves in the visible and ultraviolet spectrum.
- Adenosine-phosphoric — Relating to compounds resulting from the combination of adenosine with one or more phosphoric acid groups, playing a fundamental role in cellular energy metabolism. In a structural sense, it describes nucleoside-phosphoric acids (such as ATP, ADP, or AMP) that act as primary carriers of chemical energy and mediators in the biochemical signaling processes of living organisms.
- 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.
- Aeromotor — A mechanical device, motor, or complex technical installation that transforms the kinetic energy of air currents or wind into directly usable mechanical energy or electrical energy. In a broad structural sense, the term includes everything from high-power modern wind turbines to traditional windmills or pneumatic motors driven by compressed air.
- 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.
- 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.
- Agroecosystem — An ecosystem intentionally modified, shaped, and controlled by humans through agricultural activities for the purpose of obtaining plant or animal biomass. It integrates local biotic components with technological and anthropic elements, being characterized by a partially directed energy flow, open nutrient cycles, and a structural stability dependent on external energy and economic inputs.
- IAEA — Official Romanian acronym for the International Atomic Energy Agency (known globally by its English acronym IAEA), an autonomous organization within the United Nations system, founded in 1957 with its headquarters in Vienna. Its structural role is to promote the peaceful, safe, and exclusively civilian use of nuclear energy, implementing rigorous monitoring and inspection mechanisms to prevent the proliferation of atomic weapons.
- Alternative — Offering the possibility to choose between two or more solutions, paths, or possibilities; occurring by alternation, succeeding one another periodically (e.g., alternating current). As an adverb, it expresses the execution of facts by turns, successively.
- Alternator — A rotating electrical machine that transforms mechanical energy supplied by an internal combustion engine or another source of motion into electrical energy in the form of alternating current; an essential component of the charging system in modern vehicles.
- Starch — A macromolecular natural structural polysaccharide, with the general chemical formula (C6H10O5)n, composed of alpha-glucose units linked in linear chains (amylose) and branched chains (amylopectin). It represents the primary energy reserve substance in plants, accumulated in seeds, tubers, and fruits, serving as a fundamental element in human nutrition and a major raw material used in the food, textile, pharmaceutical, and paper industries.
- Anabolism — A fundamental phase of metabolism, characterized by the totality of biochemical processes of assimilation and biosynthesis through which the organism transforms simple nutrients from the environment into complex macromolecular compounds (proteins, nucleic acids, glycogen, and tissues). This cellular structural phenomenon requires a direct consumption of chemical energy, supplied by the breakdown of ATP molecules.
- Annihilation — A fundamental physical process of interaction and complete conversion of the mass of an elementary particle and its corresponding antiparticle into radiant energy (high-frequency photons) upon their collision. This phenomenon represents a specialized terminological variant for annihilation, being utilized primarily in astrophysics and quantum physics to describe early structural universe reactions or gamma radiation emissions from active galactic nuclei.
- Antigravity — A hypothetical phenomenon consisting of the cancellation, inversion, or neutralization of the gravitational attraction force exerted by a massive body; gravitational repulsion. In modern theoretical physics, the concept is analyzed in relation to dark energy or negative mass hypotheses.
- Anti-gravitational — Tending to cancel, counteract, or reverse the effect of the gravitational attraction force; pertaining to antigravity. In theoretical cosmology, it describes mechanical properties of dark energy, which exerts a negative pressure with an anti-gravitational effect at a cosmic scale.
- Liveliness — A state of animation, liveliness, enthusiasm, or dynamic momentum with which a person or a group carries out an activity, holds a conversation, or participates in a party. In a broad sense, it represents the contagious energy, alert pace, or active disposition that stimulates collective involvement and boosts morale.
- Structural enveloping — The act of enveloping and its result; the technical and constructive process of wrapping, covering, or externally insulating a structure; in construction, it refers specifically to the thermal insulation of a building's facades, roofs, and windows to optimize energy consumption.
- Insulated — Having undergone the process of enveloping or insulating; a building or house that has received complete exterior thermal insulation on its facades and roof; an industrial element or electrical cable enclosed within a tight protective casing.
- Arundo donax — The scientific name for the giant reed (or Spanish cane), an invasive perennial grass species of the genus Arundo, native to Asia but naturalized in the Mediterranean basin and other warm regions. The plant reaches heights of up to 6-10 meters, with very thick stems used industrially to manufacture reeds for woodwind musical instruments (clarinet, saxophone, bassoon), in eco-construction, and as a major source of renewable energy.
