Desiccant cooling
Desiccant cooling is an air-conditioning method in which a hygroscopic desiccant removes water vapor from incoming air, which is then cooled by an evaporative cooler or air conditioner.
Desiccant dehumidifier
A desiccant dehumidifier removes moisture from air by adsorbing water vapor onto a desiccant, such as silica gel, instead of condensing it on a cold surface.
Desiccation
Desiccation is the removal of water from a solid, liquid, or gas; in the laboratory it covers drying samples to constant weight and keeping dried materials dry with desiccators and drying agents.
Desiccation of the Ghaggar-Hakra river system
The desiccation of the Ghaggar-Hakra river system, also called the Sarasvati river desiccation, is the drying of a once-large river in north-west India and Pakistan.
Desiccation tolerance in ferns
Desiccation tolerance in ferns is the ability of certain ferns and lycophytes to lose almost all cellular water, suspend metabolism, and resume normal function after rehydration.
Desiccation tolerance in land gastropods
Desiccation tolerance in land gastropods is the set of adaptations, including aestivation, epiphragms, and humidity-seeking behavior, that lets snails and slugs survive losing most of their body water.
Desiccator
A desiccator is a sealed laboratory container, typically of glass, that keeps samples dry with a drying agent such as silica gel, optionally under vacuum; dried samples cool in it before weighing.
Desidae
Desidae (Pocock, 1895) is a spider family of about 324 species in 63 genera, mostly Australian and New Zealand, including intertidal Desis, sheet-web Cambridgea, and house spider Badumna; it has both cribellate and ecribellate species.
Desiderata
Desiderata, Latin for "things desired," is a 1927 prose poem by Max Ehrmann of Terre Haute, Indiana, famous for a false 1692 church attribution, Adlai Stevenson's deathbed copy, and Les Crane's 1971 Grammy-winning recording.
Desiderio Alberto Arnaz II
Desiderio Alberto Arnaz II (1894–1973), Cuban physician, businessman, and youngest mayor of Santiago de Cuba (1923–1932), later congressman; father of entertainer Desi Arnaz; jailed after the 1933 Machado overthrow and died in Miami.
Desiderosmia
Desiderosmia is the excessive craving to smell specific odours without wanting to ingest them, associated with iron deficiency anaemia; term coined by Hansen et al. 2017, distinct from pica, resolves with iron replacement.
Desidustat
Desidustat (Oxemia) is an oral HIF prolyl hydroxylase inhibitor for anemia in chronic kidney disease, developed by Zydus Lifesciences and first approved in India in 2022.
Desierto
Desierto (2015) is a Mexico-France survival thriller directed by Jonás Cuarón, starring Gael García Bernal and Jeffrey Dean Morgan, about migrants hunted by a vigilante in the Sonoran desert; Toronto FIPRESCI winner and Mexico's 2016 Oscar entry.
DESIFEST 2023
DESIFEST 2023 was the 17th edition of DESIFEST, Canada's largest free South Asian music festival, held June 3, 2023 at Yonge-Dundas Square in Toronto, headlined by Jonita Gandhi.
Design
Design is a plan or specification for constructing an object, system, or activity, or the realized result, spanning architecture, engineering, software, and the applied arts.
Design A-150 battleship
Design A-150, popularly the Super Yamato class, was a planned Imperial Japanese Navy battleship class succeeding the Yamato class, armed with six 51 cm guns.
Design and performance of immersed tube tunnels
Design of immersed tube tunnels must keep prefabricated elements buoyant during installation but permanently submerged, with watertight joints, seismic resilience, and accommodation of settlement in soft alluvial soils.
Design Automation Conference
The Design Automation Conference (DAC) is the flagship annual conference of the electronic design automation field, sponsored by ACM and IEEE and founded in 1964.
Design brief
A design brief is the written document recording a client's goals, requirements, and constraints for a building project before design begins; problems in buildings often trace back to it.
Design by committee
Design by committee is a pejorative term for a design process in which stakeholders with roughly equal decision-making power build consensus, typically yielding a compromise lacking innovation.
Design by contract
Design by contract (DbC), or programming by contract, is a software development method formulated by Bertrand Meyer in 1986, where components carry formal preconditions, postconditions, and class invariants.
Design development
Design development is the second major phase of the architectural design process, refining the approved schematic design into a coordinated solution covering structural, mechanical, electrical, and plumbing systems.
Design effect
The design effect (deff or DEFF) is a survey sampling measure comparing a complex design's variance to that of simple random sampling, coined by Leslie Kish in 1965.
Design engineer
A design engineer is an engineer who conceives, models, analyzes, and documents products or systems so they can be manufactured, a job title reported most often under mechanical engineers.
Design flood
A design flood is the flood magnitude a hydraulic structure or protected area is designed to accommodate safely, stated as a peak flow, volume, or water level.
Design for additive manufacturing
Design for additive manufacturing (DfAM) is the practice of designing parts to exploit additive manufacturing's capabilities while respecting constraints like overhang limits, build size, and powder removal.
Design for assembly
Design for assembly (DFA) is a manufacturing engineering method that guides product design to reduce part count, assembly time, and cost, pioneered by Boothroyd and Dewhurst.
Design for disassembly
Design for disassembly (DfD) is a design approach that plans products so they can be taken apart at end of life for reuse and recycling.
Design for environment
Design for environment, also called ecodesign, is the practice of integrating environmental aspects into product design and development to reduce environmental impacts throughout a product's life cycle, from raw materials to disposal.
Design for manufacturability
Design for manufacturability (DFM), in quantitative form DFMA, is an engineering methodology that shapes parts and assembly for cheaper manufacture; design fixes about 80% of manufacturing cost.
