Some areas of the world such as Washington and Oregon in the United States, and Wales in the United Kingdom, have used geographic features to store large quantities of water in elevated reservoirs, using excess electricity at times of low demand to pump water up to the reservoirs, then letting the water pass through turbine generators to retrieve the energy when electrical demands peak.

Some manufacturers have responded to this demand: Toshiba re-introduced the DE-9M connector on the Tecra laptop.

Some tour puzzles demand that certain points on the board have to be visited on the way.

Some true crime works are " instant books " produced quickly to capitalize on popular demand, while others may reflect years of thoughtful research and inquiry and may have considerable literary merit.

Some vanity presses using print on demand technology act as printers as well as sellers of support services for authors interested in self-publishing.

Some results in constructive set theory use the axiom of countable choice or the axiom of dependent choice, which do not imply the law of the excluded middle in constructive set theory.

Some say that literary criticism is a subset of literary theory.

Some mathematicians, especially in set theory, do not consider the sets and to be part of the relation, and therefore define a binary relation as being a subset of x, that is, just the graph.

Some have recently expressed doubt to how much the theory was his.

Some believe that Georg Cantor's set theory was not actually implicated by these paradoxes ( see Frápolli 1991 ); one difficulty in determining this with certainty is that Cantor did not provide an axiomatization of his system.

Some, such as computational complexity theory, which studies fundamental properties of computational problems, are highly abstract, while others, such as computer graphics, emphasize real-world applications.

Some fields, such as computational complexity theory ( which explores the fundamental properties of computational problems ), are highly abstract, whilst fields such as computer graphics emphasise real-world applications.

Some researchers still advocate a handful of alternative cosmologies ; however, cosmologists generally agree that the Big Bang theory best explains observations.

Some constructions of smooth manifold theory, such as the existence of tangent bundles, can be done in the topological setting with much more work, and others cannot.

Some of the Myers-Briggs temperaments are known to despise educational material that lacks theory.

Some workers in the field have also attempted to formulate hidden variable theories that exploit loopholes in actual experiments, such as the assumptions made in interpreting experimental data, although no theory has been proposed that can reproduce all the results of quantum mechanics.

Some modification of the Feynman rules of calculation may well outlive the elaborate mathematical structure of local canonical quantum field theory ...” So far there are no opposing opinions.

Some laissez-faire free-market advocates, like Chicago school economists, often dismiss this endogenous theory, and blame external influences, such as weather, commodity prices, technological developments, and government meddling for non-equilibrium prices.

Some Christian theologians ( particularly neo-Scholastics ) saw Cantor's work as a challenge to the uniqueness of the absolute infinity in the nature of God — on one occasion equating the theory of transfinite numbers with pantheism — a proposition which Cantor vigorously rejected.

Some radical political environmentalists who accept some form of the Gaia theory call themselves Gaians.

Some refer to this political activity as a separate and radical branch of the ecology movement, one that takes the axioms of the science of ecology in general, and Gaia theory in particular, and raises them to a kind of theory of personal conduct or moral code.

Some constitutions or fundamental laws provide for a head of state who is not only in theory but in practice chief executive, operating separately from, and independent from, the legislature.

Some of the characteristics of a presidential system ( i. e., a strong dominant political figure with an executive answerable to them, not the legislature ) can also be found among absolute monarchies, parliamentary monarchies and single party ( e. g. Communist ) regimes, but in most cases of dictatorship, their stated constitutional models are applied in name only and not in political theory or practice.

Some scholars have seen Perses as a literary creation, a foil for the moralizing that Hesiod develops in Works and Days, but there are also arguments against this theory.
