• Hardware architecture — A shortened term for hardware architecture or, specifically, a reference to Arch Linux, an independent operating system distribution based on the principles of simplicity, modernity, and a 'do-it-yourself' minimalist approach. This structural ecosystem places complete control in the hands of the user, operating on a rolling release model and utilizing the Pacman package manager for direct resource management.
• Silver-plater — A person or craftsman specialized in the technique of silver-plating, namely in coating base metals with a thin layer of silver through galvanic, chemical, or mechanical methods; as an adjective, it describes a factor, substance, or device used in the argent plating process. In a modern industrial sense, the term refers to the electroplating operator managing electrolytic baths and controlling the deposition thickness of the precious metal on various components or circuits.
• Area — The measurement of a two-dimensional surface area expressed in square units; a solo vocal musical composition with instrumental accompaniment, typically part of an opera or oratorio; a territory defined by specific common characteristics, such as geographic location or the distribution of a biological species.
• Arietta — A small, short, and simple aria, featuring a pronounced melodic character and often a rhythmic dance structure, characteristic of comic opera or vocal performances of the 17th and 18th centuries. This structural musical form is distinguished by the absence of complex dramatic developments or difficult vocal ornamentations, emphasizing fluidity.
• Arioso — A vocal or instrumental piece or musical fragment with a pronounced melodic and cantabile character, structurally situated, in style and form, between a recitative and an aria; as an adverb, it indicates the performance mode of a composition, requiring it to be interpreted in a melodious, cursive, fluid, and vocally expressive style.
• Arytenoidectomy — A high-precision surgical intervention consisting of the partial or total excision of one or both arytenoid cartilages of the larynx. This structural surgical procedure is primarily performed to treat bilateral vocal cord paralysis in abduction (median position), aiming to widen the restricted glottic space and alleviate severe respiratory insufficiency, thereby restoring a functional airway without completely compromising phonation.
• Arithmetic — Pertaining to arithmetic, referring to arithmetic, or based on the fundamental operations and rules of numbers. In mathematics, the term qualifies a progression where each term is obtained by adding a constant ratio to the preceding term, or a calculation, operator, or mean obtained by summing elements and dividing them by their total number.
• Shipowner — A natural or legal person who exploits a commercial vessel in their own name, ensuring its equipping, provisioning, and outfitting for navigation, regardless of whether they are the legal owner of the ship or merely its charterer. The shipowner bears the legal and economic responsibility for maritime transport operations and the safety of the sailing crew.
• Armida — A famous female character, a seductive sorceress in the epic poem 'Jerusalem Delivered' (Gerusalemme liberata) written by Torquato Tasso in the 16th century; by extension, the name became an eponym for a fascinating woman capable of enchanting or manipulating men through her sensual charms. This character inspired numerous musical operas, paintings, and plays during the Baroque and Romantic eras.
• Artel — A historical form of cooperative association or autonomous production guild, specific to the Russian Empire and later the early Soviet period, in which members (artisans, fishermen, peasants, or laborers) voluntarily united to carry out a common economic activity. Within an artel, labor was collective, income was distributed according to contribution or agreement, and members shared joint liability for the obligations assumed, a model occasionally imported into neighboring areas or referenced in period economic literature.
• Arteriectomy — A surgical operation consisting of the partial or total resection of a diseased or obstructed artery, usually followed by the restoration of blood flow through a vascular graft (anastomosis) or a synthetic prosthesis. It is a complex procedure utilized in treating severe aneurysms or acute arterial occlusions.
• Arterioplasty — A surgical procedure for the reconstruction, repair, or plastic remodeling of the wall of an artery that is damaged, narrowed, or affected by an aneurysm or trauma. This vascular surgical intervention may involve using a synthetic patch (such as Dacron or PTFE) or an autologous patch (a vein segment harvested from the patient) to widen the vascular lumen, restore normal blood flow, and prevent downstream tissue ischemia.
• Arteriorrhaphy — An emergency or elective surgical procedure consisting of the direct structural suturing of an accidentally severed, ruptured, or perforated artery wall. This high-precision operative act restores the anatomical continuity of the vessel and re-establishes normal blood flow to the irrigated tissues, preventing severe ischemia and amputation of the affected segment.
• Arteriotome — A specialized surgical instrument, such as a scalpel or microscopic finishing knife, used for the precise longitudinal or transverse sectioning of an artery wall. This structurally high-precision device is designed to minimize tissue trauma to the vascular tunics during the initiation of reparative procedures.
• Arteriotomy — A surgical intervention consisting of the operative incision of an artery wall, structurally performed to allow the extraction of a thrombus (thrombectomy), the insertion of a dilation catheter, or the creation of an anastomosis. It represents a fundamental operative step executed under strict temporary hemostasis conditions.
• Industrial caster — A specialized worker or technical operator responsible for adjusting, starting, and monitoring the structural parameters of an industrial aggregate or pouring molten materials; a caster or founder. In certain isolated industrial registers, the term defines the person calibrating heavy machinery to ensure correct finishing of mechanical pieces.
• Arthrectomy — A surgical operation consisting of the total or partial excision of a diseased or structurally compromised joint; an articular resection. It is an invasive procedure utilized in severe cases of bone destruction, incurable joint infections, or tumors, often representing the preliminary stage of an arthrodesis or arthroplasty.
• Arthroclasia — A surgical operation or forced orthopedic maneuver consisting of breaking or destroying fibrous adhesions and vicious callus within an ankylosed joint, performed with the purpose of restoring its lost structural mobility. This invasive procedure is typically executed under general anesthesia to allow the sudden mobilization of blocked bony segments.
• Arthrodesis — Surgical intervention aimed at the permanent fixation of a movable joint through artificial bone fusion, designed to restore skeletal stability and eliminate severe chronic pain. This procedure permanently blocks movement in the treated segment, serving as a final therapeutic solution for advanced joint destruction caused by arthrosis, major trauma, or congenital deformities.
• Storming — A noun or variable adjective designating a person, military force, army, or collective entity of the feminine gender that executes an assault, violent attack, or direct offensive. In a structural and military sense, it refers to shock troops or tactical units (e.g., storming companies) intended to pierce enemy defensive lines, while figuratively describing the offensive, energetic, and impetuous behavior of a person or group.
