Dehn surgery is a construction in 3-manifold topology that removes a solid torus and reglues it along a slope p/q, yielding every closed orientable 3-manifold.
Dehn–Sommerville equations
The Dehn–Sommerville equations are linear relations among the face numbers of simplicial or simple polytopes, found by Max Dehn in 1905 and Sommerville in 1927.

Dehumanization
Dehumanization is the attribution of subhuman qualities to people or groups. Key frameworks are Haslam's dual model (animalistic vs mechanistic) and infrahumanization; it is linked to violence, genocide propaganda, and contested trait-based measurement.
Dehumanization of Jews and Israelis in Palestinian discourse
Dehumanization of Jews and Israelis in Palestinian discourse refers to documented animal comparisons, disease metaphors, and eliminationist language in Palestinian Authority media, Hamas communications, and school materials.
Dehumanization of Palestinians in Israeli discourse
Dehumanization of Palestinians in Israeli discourse: documented animalistic and subhuman rhetoric by Israeli officials and media, notably Gallant's 'human animals' and Netanyahu's Amalek references, analyzed by scholars, NGOs, and UN bodies.
Dehumanized (song)
"Dehumanized" is a 2026 deathcore single by Bring Me the Horizon, the sole new closing track on Count Your Blessings | Repented, their 20th-anniversary re-recording of their 2006 debut, written by Oliver Sykes and Lee Malia.
Dehumanizer
Dehumanizer is a 1992 studio album by Black Sabbath, reuniting Ronnie James Dio, Tony Iommi, Geezer Butler, and Vinny Appice for one of the band's heaviest records.
Dehumidifier
A dehumidifier is a device that removes water vapor from air, most commonly a home appliance that condenses moisture onto a refrigerated coil and collects the water.
Dehydrated hereditary stomatocytosis
Dehydrated hereditary stomatocytosis, also called hereditary xerocytosis, is a rare autosomal dominant hemolytic anemia caused mainly by PIEZO1 gain-of-function mutations, causing red cell dehydration, iron overload, and post-splenectomy thrombosis risk.
Dehydration
Dehydration: deficiency of body water from losses exceeding intake, caused by diarrhea, vomiting, sweating, fever, or diuretics; treated with fluids, oral rehydration salts, or IV therapy.
Dehydration of newborn
Dehydration of newborn (neonatal dehydration, ICD-11 KB63.1) is excessive body water loss in a newborn; the key form is hypernatremic dehydration from inadequate breast milk intake, treated with slow sodium correction.
Dehydration reaction
A dehydration reaction is a chemical reaction that combines two functional groups with the loss of a molecule of water, most often converting an alcohol to an alkene.
Dehydrin
Dehydrins (DHNs), also called LEA group 2 or D11 proteins, are intrinsically disordered, highly hydrophilic plant stress proteins defined by a lysine-rich K-segment, induced by drought, cold, and salinity, protecting membranes, enzymes, and DNA.
Dehydroabietic acid
Dehydroabietic acid (DHAA) is a tricyclic abietane-type diterpene resin acid and major, oxidation-resistant component of rosin, formed as abietic acid aromatizes during aging and during industrial rosin processing.
Dehydroacetic acid
Dehydroacetic acid is a pyrone derivative used mainly as a preservative against yeasts and molds in cosmetics, food, and pharmaceuticals; its sodium salt is the more water-soluble form.
Dehydroalanine
Dehydroalanine (Dha) is a non-proteinogenic unsaturated amino acid that occurs in peptide antibiotics such as nisin, forms during food processing, and serves in chemical biology as a tag for protein modification.
Dehydroamino acid
A dehydroamino acid is a noncanonical amino acid with a double bond between the α- and β-carbons, occurring in peptide natural products such as nisin.
Dehydroascorbic acid
Dehydroascorbic acid, or dehydroascorbate (DHA), is the two-electron oxidation product of vitamin C that cells take up through glucose transporters and recycle back to ascorbate.
Dehydrodolichyl diphosphate synthase
Dehydrodolichyl diphosphate synthase (DHDDS), also called DedolPS, is the catalytic cis-prenyltransferase subunit that with NgBR forms the human enzyme making dehydrodolichyl diphosphate (C85-100), the dolichol-phosphate precursor for N-linked glycosylation; mutations cause retinitis pigmentosa 59 and epileptic encephalopathy.
Dehydroepiandrosterone
Dehydroepiandrosterone (DHEA), with its sulfate DHEAS, is the most abundant adrenal steroid hormone in humans, a prohormone converted to testosterone and estradiol; isolated in 1934, levels decline about 10% per decade after peaking in early adulthood.
Dehydroepiandrosterone sulfate
Dehydroepiandrosterone sulfate (DHEA-S, DHEAS) is the sulfate ester of the steroid DHEA, made almost entirely by the adrenal cortex and the most abundant steroid in blood.
Dehydrogenation
Dehydrogenation is a chemical reaction that removes hydrogen from a molecule; industrially, propane dehydrogenation produces about 10% of the world's propylene using chromium or platinum catalysts.
Dehydrogenation of amine-boranes
Dehydrogenation of amine-boranes is the release of dihydrogen from amine-borane adducts such as ammonia-borane, studied for hydrogen storage because these bench-stable compounds carry high hydrogen content.
