#base

• Despicable / Vile — A quality designating a person, act, or attitude of a base nature, completely devoid of dignity, honor, or moral scruples; causing profound revulsion, contempt, disgust, or loathing through its wickedness or baseness.
• Abjection / Vileness — The state, quality, or character of being abject; behavior, act, attitude, or manifestation of extreme baseness or wickedness. It can also denote a state of profound moral decay or a vulgar, insulting expression.
• Abjection — A state of extreme moral degradation, baseness, or vileness that provokes repulsion and contempt. In a philosophical and psychological sense, the term denotes either an act or behavior that flagrantly violates the norms of human dignity, or the feeling of total self-depreciation and humiliation experienced by an individual facing their own social or moral decline.
• Acroterium — A learned technical form or direct transliteration of the Latin term acroterium; it represents the small plinth or decorative finishing element placed at key points of aclassical pediment to support statues or plant ornaments. Its structure ensures the correct weight distribution of decorative sculptures onto the building's entablature support.
• Sacrum — An obsolete, rare graphic variant or faulty transcription for the sacrum bone (os sacrum); the large triangular bony piece located at the base of the vertebral column, formed by the structural fusion of the five sacral vertebrae, articulating laterally with the iliac bones to close the pelvic girdle.
• Aquatypia — A rare artistic or technical printing process for reproducing graphic images using special water-based inks applied onto treated plates; also, it designates the print or final artwork obtained through this structural method. The technique ensures visual effects of remarkable transparency, similar to watercolors, while eliminating toxic solvent-based chemical pigments.
• Added — Having been placed, included, or joined next to an existing element or quantity to enlarge, complete, or integrate it; existing in addition to the initial structure. In economics, the term is heavily used in the phrase 'value-added tax' (VAT), designating the extra value created during the production and distribution process of a good.
• Adenine — A fundamental purine nitrogenous base, with a heterocyclic structure composed of two condensed rings, an essential component of nucleic acids (DNA and RNA). It plays a crucial structural role in storing and transmitting genetic information through specific hydrogen bonds with thymine or uracil, being also a key element in molecules vital for cellular energy metabolism, such as ATP.
• Ader — A proper name used as a surname or given name across various cultural spaces, with Germanic or Hebrew origins; it can also designate geographical entities, such as the Ader River, or prominent historical figures (such as Clément Ader, a French aviation pioneer). In a structural context, the name reflects specific genealogical identities, integrated into international onomastic and historical databases.
• Adromischus trigynus — A dwarf, compactly branched perennial succulent plant species in the Crassulaceae family, native to a wide range in South Africa (from the Great Karoo and Northern Cape to the Free State) and Namibia. It features a tuberous, much-branched base bearing dense, elliptic to orbicular leaves with distinctive acute, horny margins wrapping their upper sections. The grayish-green foliage is heavily mottled with chocolate-brown or purplish-maroon spots, earning it the common name 'Calico Hearts'. In late spring, it produces long inflorescences up to 35 cm tall with pale yellowish-green tubular flowers tinged with white or pink.
• Airbase — A military airbase or a large aeronautical complex comprising airfields, takeoff and landing runways, hangars, repair shops, fuel and ammunition depots, as well as the logistical infrastructure necessary for the stationing, maintenance, and operation of military or commercial aircraft.
• Aero club — A sports association, club, or aeronautical organization aimed at promoting, practicing, and developing recreational flight activities, piloting, skydiving, gliding, or aeromodelling. The term also designates the material base of such an association, including the airfield, hangars, aircraft, and training facilities.
• Minimum agrotechnics — A mandatory and minimum complex of agronomic rules, measures, and practices (such as proper tillage depth, seed cleaning, crop rotation) that must be rigorously applied to a field to ensure a baseline agricultural yield and prevent structural soil degradation. As an adjective, it describes systems or practices reduced to essential conservation elements.
• Ajud — An erroneous spelling form, rare variant, or graphic confusion for the municipality of Adjud, located in Vrancea County, Romania; in other historical administrative or cartographic contexts, it may be a partial transcription or a small regional toponym. As a base entity, it reflects the municipality of Adjud, a major railway and road junction in the eastern part of the country, positioned at the intersection of national transport highways.
• Alkali — A generic name given to the hydroxides of alkali metals (such as sodium, potassium) and alkaline earth metals, as well as ammonium hydroxide. In a traditional chemical sense, it refers to any water-soluble base capable of neutralizing acids, turning red litmus paper blue, and forming salts through combination reactions.
• Alkalemia — The physiological or pathological state characterized by an increase in blood alkalinity beyond normal limits, resulting in an arterial pH value greater than 7.45. This structural acid-base imbalance can be caused by the accumulation of bases or the excessive loss of acids from the body, being closely correlated with severe metabolic or respiratory disorders.
• Alkalimetric — Pertaining to alkalimetry; based on the measurement of alkalinity or the concentration of bases in a solution. The term describes the methods, instruments, or reagents utilized in quantitative titration analyses, where the volume of a standard acid of known concentration determines the purity of the analyzed alkaline substance.
• Alkalimetry — A method of quantitative volumetric analysis that consists of determining the concentration of a base or the amount of free alkaline substance in a solution by progressive titration with an acid solution of known concentration (standard acid). The process uses acid-base indicators or potentiometric methods to highlight the chemical equivalence point where neutralization is complete.
• Alkalimeter — An apparatus or laboratory instrument utilized in volumetric chemical analyses to measure the amount or concentration of free bases (alkali) in a liquid mixture. Historically, the term referred to special graduated glass vessels (early burettes), while in a modern context, it can describe automatic titration modules configured for basic determinations.
• Alkalosis — A disturbance of the acid-base balance in the body, characterized by an increase in plasma pH above the normal value of 7.45, resulting from the accumulation of alkaline substances (bases) or excessive loss of acids. It can be metabolic (triggered by severe vomiting or bicarbonate ingestion) or respiratory (caused by hyperventilation).
