Nongfu Spring (农夫山泉) is China's largest packaged drinking water company, founded by Zhong Shanshan in 1996 and listed in Hong Kong, selling water from natural springs alongside tea and juice.
Nongga wollyeongga
Nongga wollyeongga (농가월령가, "Song of the Farmhouse by Monthly Order") is an early 19th-century Korean gasa poem by Jeong Hak-yu describing the year's farm work month by month.
Nongjian Tao
Nongjian Tao (N. J. Tao), 1963–2020, was a Chinese-born physicist and electrical engineer at Arizona State University who invented the STM break junction for measuring single-molecule conductance.
Nongqawuse
Nongqawuse (c. 1841–1898) was a Xhosa prophetess whose visions in April 1856 set in motion the Xhosa cattle-killing, in which followers slaughtered their cattle expecting a resurrection that never came.
Nongsang yishi cuoyao
Nongsang yishi cuoyao (农桑衣食撮要) is a Yuan dynasty agricultural almanac by the Uyghur author Lu Mingshan, listing farm and sericulture tasks month by month; it stands among the three great agricultural books of the Yuan.
Nongshim
Nongshim (농심) is a South Korean ramyeon and snack manufacturer founded by Shin Choon-ho in 1965, Korea's largest instant-noodle maker, known for Shin Ramyun and Neoguri.
Nonheme iron
Nonheme iron is dietary iron not bound in a heme ring, found in plant foods, fortified products, and meat, with absorption strongly shaped by other meal components.
Nonholonomic constraints
Nonholonomic constraints are velocity constraints on a mechanical system that cannot be integrated into position constraints; they arise from rolling without slipping and from sliding contact, such as a skate on ice.
Nonholonomic system
A nonholonomic system is a mechanical system subject to velocity constraints that cannot be integrated into position constraints; rolling spheres and wheeled vehicles are standard examples.
Nonhomologous End-Joining (NHEJ)
Nonhomologous end-joining (NHEJ), also called classical or canonical NHEJ, is the Ku-dependent DNA double-strand break repair pathway that directly reseals broken DNA ends without a homologous template; it operates throughout the cell cycle, is essential for V(D)J recombination, and has a Ku-independent backup, alternative end joining (MMEJ).
Noni Hazlehurst
Noni Hazlehurst (Leonie Elva Hazlehurst, born 1953) is an Australian actor and presenter, star of Play School 1978-2001, Better Homes and Gardens, A Place to Call Home, and the Logie Hall of Fame (2016).
Noni juice
Noni juice, from Morinda citrifolia (Indian mulberry, cheese fruit), is a fermented tropical fruit drink marketed as a dietary supplement. Long used in Polynesian medicine and approved as an EU novel food, it shows antioxidant activity in vitro but no proven human health benefits, with liver and potassium cautions.
Noni Madueke
Noni Madueke (Chukwunonso Tristan Madueke, born 2002, Barnet, London) is an English left-footed right winger for Arsenal and England; ex-Crystal Palace, Tottenham, PSV Eindhoven (80 apps, 20 goals) and Chelsea; 16 England caps, 2026 World Cup squad.
Noninfectious intermediate uveitis
Noninfectious intermediate uveitis, also called pars planitis when idiopathic, is chronic inflammation of the vitreous, pars plana, and peripheral retina; treated with corticosteroids, immunosuppressants, and adalimumab.
Noninvasive prenatal testing
Noninvasive prenatal testing, also known as Noninvasive Prenatal Screening, is a maternal blood test that screens for fetal chromosomal abnormalities. It is a screening test, not a diagnostic one.
Nonito Donaire
Nonito Gonzales Donaire Jr., known as the Filipino Flash, is a Filipino boxer who won world titles in four weight divisions and at 38 became the oldest bantamweight world champion.
Nonivamide
Nonivamide (pseudocapsaicin, N-vanillylnonanamide, CAS 2444-46-4) is a synthetic capsaicinoid, the amide of vanillylamine and nonanoic acid, a TRPV1 agonist used in pepper sprays, topical rubefacients, and as a flavoring.
Nonlinear acoustics
Nonlinear acoustics is the branch of acoustics studying sound waves so intense that the wave's own pressure changes the medium, causing waveform distortion, shocks, and harmonic generation.
Nonlinear anomalous Hall effect
The nonlinear anomalous Hall effect is a second-order transport effect in which transverse current grows as the square of the applied field, without magnetism or broken time-reversal symmetry.
Nonlinear autoregressive distributed lag model
The nonlinear autoregressive distributed lag (NARDL) model is a single-equation error correction model, introduced in 2014, that estimates separate effects of positive and negative changes in each explanatory variable.
Nonlinear digital self-interference cancellation
Nonlinear digital self-interference cancellation is a signal-processing technique used in full-duplex wireless radios, digitally reconstructing and subtracting their own transmitter's nonlinear distortion, chiefly from power amplifier saturation, to enable simultaneous same-frequency transmission and reception.
Nonlinear dimensionality reduction
Nonlinear dimensionality reduction is a family of machine learning methods that convert high-dimensional data into low-dimensional representations while preserving curved manifolds and neighborhoods, used for visualization and clustering.
Nonlinear dynamic inversion
Nonlinear dynamic inversion (NDI) is a flight control method that cancels a vehicle's nonlinear dynamics through feedback; its incremental variant, INDI, is among the most active approaches in flight control law design.
Nonlinear filtering
Nonlinear filtering, or nonlinear filtering theory, is the recursive Bayesian estimation of a hidden system state from noisy, partial observations, solved approximately by methods like the particle filter.
Nonlinear finite element analysis
Nonlinear finite element analysis (nonlinear FEA) is a computational method for structures whose stiffness, geometry, or boundary conditions change during loading, so a linear solution cannot be scaled.
Nonlinear Fourier transform
The nonlinear Fourier transform, also called the inverse scattering transform, decomposes a nonlinear signal into spectral components that evolve simply, much like the ordinary Fourier transform.
Nonlinear frequency-division multiplexing
Nonlinear frequency-division multiplexing (NFDM) is an optical fiber technique that encodes data on the nonlinear Fourier spectrum, making fiber nonlinearity part of the signal design rather than a distortion to compensate.
