n-type

An n-type semiconductor is silicon that has been deliberately doped with a tiny amount of an element like phosphorus, which has five outer electrons instead of silicon's four. The extra electron from each dopant atom is free to move, so electric current in n-type material is carried mainly by negatively charged electrons (n for negative). Paired with p-type material, where current is carried by positive holes, it forms the p-n junctions at the heart of diodes, transistors and solar cells.

Example: In a silicon solar cell, sunlight striking the n-type layer knocks electrons loose, and the junction with the p-type layer sweeps them into an electric current, which is how the panel generates power.

The narrow base, in UPSC economy, usually refers to India's narrow tax base: the small share of the population paying direct taxes relative to the country's size, which limits revenue and forces reliance on indirect taxes. Widening the base through formalisation and better compliance is a recurring Budget and Economic Survey theme. For UPSC, it anchors GS-3 answers on taxation, fiscal capacity and inclusive growth.

nitrification

Nitrification is the microbial step of the nitrogen cycle in which ammonia or ammonium is oxidised first to nitrites and then to nitrates. It is carried out by nitrifying bacteria such as Nitrosomonas and Nitrobacter in soil and water, converting nitrogen into the nitrate form that plants can readily absorb. Because nitrates dissolve easily in water, heavy nitrification also makes nitrogen prone to leaching into groundwater.

NNP = GNP − depreciation

NNP is Net National Product, equal to Gross National Product minus depreciation of capital assets. It measures the net income earned by a country's residents (including net factor income from abroad) after accounting for capital wear and tear. Divided by population it gives per-capita net national income, a welfare indicator. It matters for UPSC because the GNP-NNP distinction and national income identities are routine prelims questions.

Economists argue it should be minimised in favour of merit goods like research, irrigation and extension that benefit all. For UPSC it is the fiscal-economics vocabulary for the subsidy-versus-investment debate.

Example: Economists classify free farm power as non-merit expenditure because its gains accrue mainly to larger farmers.

non-point source

Non-point source pollution comes from diffuse, scattered origins rather than a single identifiable outlet such as a factory pipe, which makes it harder to monitor and regulate than point-source pollution. Runoff carrying fertilisers, pesticides, and silt from farmland into rivers is the classic case. Controlling it requires landscape-level measures like buffer strips and better farming practices rather than end-of-pipe treatment.

Example: Agricultural runoff washing nitrates and phosphates into rivers and lakes, triggering algal blooms and eutrophication.

Nuclear power is

Nuclear power is electricity generated from controlled nuclear fission, in which heavy nuclei such as uranium-235 split and release heat that drives turbines. Its key features are very high energy density, near-zero carbon emissions during operation, and demanding long-term safety and waste management. It matters for UPSC GS-3 because India's three-stage nuclear programme and new reactor capacity are central to energy-security and clean-energy-transition questions.

Example: the Kudankulam Nuclear Power Plant in Tamil Nadu, India's largest nuclear power station

Nuclear Suppliers Group

The Nuclear Suppliers Group (NSG) is a 48-member export-control regime that coordinates controls on civilian nuclear material, equipment, and dual-use technology to prevent weapons proliferation. Formed in response to India's 1974 nuclear test, it first met in London in November 1975. For UPSC, the NSG matters because India, a non-NPT state, won a 2008 waiver enabling civilian nuclear trade but remains blocked from membership, largely by China.

Example: The Indo-US civil nuclear deal of 2008 led directly to the NSG's waiver for India, opening global uranium supplies for India's reactors.

Nuclear Suppliers Group waiver

The September 2008 decision by the Nuclear Suppliers Group (NSG), a 48-nation export-control regime, granting India a country-specific exemption from its rule requiring full-scope IAEA safeguards as a condition for nuclear trade. The waiver opened India to international civil nuclear commerce in fuel, reactors and technology despite India not being a signatory to the NPT, and made the India-US 123 Agreement operational. It marked India's effective integration into the global civilian nuclear order.

Example: After the 2008 waiver, India signed uranium supply agreements with countries such as France, Russia and Kazakhstan for its safeguarded reactors.

nuclearisation

Nuclearisation is the spread of nuclear weapons capability to additional states, or the growing salience of nuclear weapons in a region's security calculations. It heightens deterrence but also the risks of miscalculation, arms racing and crisis instability. For GS-2 international relations and GS-3 security it is central to debates on non-proliferation, the NPT's limits and strategic stability in regions like South Asia, the Korean peninsula and West Asia.

Example: India's Pokhran-II tests of May 1998, followed within weeks by Pakistan's Chagai tests, nuclearised South Asia.

nucleic acid vaccines

Nucleic acid vaccines use genetic material, DNA or messenger RNA, instead of a weakened or killed pathogen, instructing the body's own cells to produce a pathogen protein that triggers an immune response. DNA vaccines use engineered plasmids while mRNA vaccines use lipid-encapsulated RNA; both platforms can be designed and manufactured faster than conventional vaccines. They need no live virus handling, which simplifies production.

Example: ZyCoV-D, the world's first DNA vaccine for human use, developed in India and granted emergency use authorisation in August 2021.

nude

Nude in art history denotes the unclothed human figure treated as a subject of sculpture and painting rather than as mere nakedness. Indian art has a long tradition of the nude and semi-nude figure, from yakshi brackets to temple sculpture, where the body expresses ideals of beauty, fertility and divinity. For GS-1 art and culture it appears in questions on the aesthetics and symbolism of ancient and medieval Indian sculpture.

Example: The temples of Khajuraho, built roughly between 950 and 1050 CE, are celebrated for their nude and erotic sculpture.

number theory

Number theory is the branch of pure mathematics concerned with the properties of integers, especially prime numbers, divisibility, modular arithmetic, and Diophantine equations. Though highly abstract, it underpins modern cryptography: the RSA algorithm that secures digital communication rests on the difficulty of factoring large primes. It remains one of the oldest and most active areas of mathematical research.

Example: Srinivasa Ramanujan's pioneering work on partitions, highly composite numbers, and modular forms.

Numismatics

Numismatics is the study of coins, medals and currency, and a key source for reconstructing ancient Indian history where texts are thin. Punch-marked coins, Indo-Greek bilingual issues and Gupta gold dinaras reveal rulers, trade routes and economic conditions. James Prinsep's decipherment of the Brahmi and Kharosthi scripts on coins unlocked Ashokan history. It matters for UPSC prelims, which regularly asks about coin types and the dynasties that issued them.

Example: James Prinsep's 1837 decipherment of Brahmi on ancient Indian coins

nutrient cycling

Nutrient cycling is the continuous movement and reuse of chemical elements such as carbon, nitrogen, and phosphorus through ecosystems, from soil, water, and air into organisms and back through decomposition. Unlike energy, which flows one way and dissipates as heat, nutrients are recycled indefinitely by decomposers such as fungi and bacteria. Healthy nutrient cycles keep ecosystems productive without external inputs.

Example: Fallen leaves decomposing into humus that returns nitrogen and phosphorus to forest soil.

Nutrient-Based Subsidy

The Nutrient-Based Subsidy (NBS) is India's fertilizer subsidy regime, introduced in April 2010, under which subsidy is paid per kilogram of nutrient (nitrogen, phosphorus, potassium, sulphur) in phosphatic and potassic fertilizers. Urea was kept out and remains price-controlled, which skewed usage toward nitrogen and distorted the NPK ratio. It matters for UPSC GS-3 as the core of fertilizer-subsidy and soil-health debates.

Example: the April 2010 rollout of NBS for phosphatic and potassic (P&K) fertilizers

Nutrient-Based Subsidy (NBS)

The Nutrient-Based Subsidy is the 2010 policy that fixed per-kilogram subsidies on the nutrients N, P, K and S in phosphatic and potassic fertilisers, letting retail prices vary. It freed P and K prices while keeping urea price-controlled, unintentionally skewing use toward cheap urea. For UPSC it is the key fertiliser-pricing reform and the source of the NPK imbalance.

Example: The doubling of DAP prices after NBS, while urea stayed cheap, shows the policy's distortionary side effect.
