• Antipruritic — Calming, reducing, or eliminating the sensation of itching (pruritus) on the skin or mucous membranes. It refers to chemical substances, pharmaceutical preparations (creams, lotions, gels), or therapeutic treatments acting locally or systemically by blocking histamine receptors or desensitizing peripheral nerve endings, providing rapid relief from cutaneous discomfort.
• Antwerpen — A major port city in Belgium, the capital of the eponymous province in the Flanders region, situated on the Scheldt river; it is the second-largest port in Europe, a global economic hub, and the undisputed international capital of the diamond trade and cutting industry.
• Anvers — The French designation and traditional Romanian usage for the Flemish port city of Antwerpen in Belgium; it represents a commercial, industrial, and logistical hub of capital European importance and the historic global center of diamond trading.
• Ammonium hydroxide — An aqueous solution of ammonium hydroxide (NH₄OH), a clear, colorless liquid with a pungent, suffocating, and strongly alkaline odor, obtained by dissolving ammonia gas in water; it is widely used in the chemical industry as a laboratory reagent, in producing nitrogen fertilizers, cleaning agents, textiles, or as a refrigerant medium.
• Aptian — An upper geological stage of the Lower Cretaceous, chronologically situated between the Barremian and the Albian, structurally characterized by massive sedimentary deposits rich in ammonites and the expansion of specific marine faunas; as an adjective, it describes the rocks, formations, or fossils that formed during this period of Earth's history.
• Arginase — A highly crucial hydrolytic enzyme, primarily located in the cytoplasm of hepatocytes, which catalyzes the final phase of the urea cycle. This structural biocatalyst splits arginine into ornithine and urea, facilitating the efficient elimination of toxic ammonia resulting from protein metabolism and thus preventing severe neurological disorders.
• Arietites — A fossil genus of ammonites (extinct marine cephalopod mollusks) from the Early Jurassic period, characterized by a large, planospiral shell with prominent transverse ribs and a distinct central keel; the name suggests the resemblance of the coiled shell to the horns of the Egyptian god Ammon or a ram, serving as a critical index fossil for dating geological strata of the Sinemurian stage.
• Aspidoceras — An extinct genus of ammonites (coiled marine cephalopod mollusks) in the family Aspidoceratidae, which lived during the Late Jurassic and Early Cretaceous periods. Fossils of this genus are recognized by their robust, evolute shell, characterized by distinctive rows of nodes or spines arranged on the flanks, used by paleontologists as index fossils for dating marine geological strata.
• Attalos — The name borne by several famous kings of the Attalid dynasty who ruled the Hellenistic kingdom of Pergamon in Asia_Minor, the most renowned being Attalos II (founder of Antalya) and Attalos III, who bequeathed his kingdom to the Roman Republic. In archaeology, the name is closely linked to the Stoa of Attalos, a monumental structure reconstructed in the Agora of Athens.
• Downstream — The part of a watercourse located in the direction of the current, toward the mouth (as opposed to amonte); (adverbially) in the direction of the water flow; (in economics and law) a written personal guarantee, usually on a bill of exchange or promissory note, whereby a person (avalist) binds themselves to pay the mentioned amount if the primary debtor fails to fulfill their obligation.
• Avalanche — A large mass of snow, ice, rocks, or earth that suddenly detaches from the steep slope of a mountain and moves rapidly downward, destroying everything in its path; (figuratively) a sudden, massive, and overwhelming accumulation of events, letters, requests, or emotional states.
• Starling — The upstream part of a bridge pier, projecting forward and specially shaped (pointed, wedge-like, or ogival) to split the water current, guide the flow, and protect the structure against water pressure, ice jams, or floating debris carried by the river. It serves as the frontal safety component of a bridge infrastructure facing the hydrological flow.
• Nitrate — A salt or ester of nitric acid containing the NO3 functional group; in common and agricultural language (often called nitrate), it refers to chemical fertilizers used for enriching the soil with nitrogen, whose excessive use can lead to the pollution of groundwater.
• Baculite — A member of the extinct genus Baculites, representing an Upper Cretaceous ammonite characterized by an almost completely straight, elongated, rod-shaped calcareous shell, unlike classic spiraled ammonites. Geologically, baculite fossils are utilized as highly important index fossils for dating marine sedimentary layers and reconstructing prehistoric ecosystems.
