Stability of isotopes is affected by the ratio of protons to neutrons, and also by presence of certain " magic numbers " of neutrons or protons which represent closed and filled quantum shells.

Within the EU, accusations have been made that off-budget enterprises are sometimes used by national governments to circumvent the Stability and Growth Pact, as public debt will no longer appear in the annual budget deficit and in total public debt, which may not exceed certain percentages of GDP ( 3 % and 60 % respectively ) under the Maastricht criteria.

Stability can often be ensured using only the proportional term.

Stability of a strategy can be difficult to prove, but usually, a well-formed strategy will predict gene frequencies.

Stability nor fixity can be directly affected by the subject at hand.

Stability Pact can mean

* J. P. Ostriker and P. J. E. Peebles, " A Numerical Study of the Stability of Flattened Galaxies: or, can Cold Galaxies Survive?

Other new electronic systems include Trailer Stability Assist which can adjust the throttle and brakes to prevent a dangerously swaying trailer.

Stability testing can refer to:

Stability can also be negatively affected, and enhancements such as extended wheelbase by welding extensions on the front and rear dropouts can benefit stability.

Stability is much more difficult to define, but can be generally thought of in two ways.

Stability can thus be significantly improved by installing drainage paths to reduce the destabilising forces.

Safety can be improved by providing computer controlled intervention of vehicle controls with systems such as Electronic Stability Control ( ESC ), adaptive cruise control and Lane Assist Systems.

A 1979 Econometrica paper, " On Hotelling's ' Stability in Competition '" by Aspremont, Gabszewicz, and Thisse, argues that while the price competition in Hotelling's paper correctly addressed the Bertrand paradox, explaining how firms can compete in prices and still make positive profits, Hotelling made an error in reasoning in the second part of the paper where he attempts to endogenize the locations of the firms in his model and establishes his " law ".

Stability can be determined by examining the roots of this equation e. g. using the Routh array, but this method is somewhat tedious.

A very detailed mathematical treatment of this from the point of view of the Navier – Stokes equations and the equations of thermodynamics can be found in the first third of Subrahmanyan Chandrasekhar's Hydrodynamic and Hydromagnetic Stability, originally published in 1961 by Oxford, and republished by Dover in 1981.

EMU and in particular the Stability and Growth Pact as well as the Broad Economic Policy Guidelines ( which were introduced as an instrument to realise the goals set down in the Lisbon Agenda ) can be considered a sort of “ proto-OMC ” with comparatively hard sanctioning mechanisms.

The new Ypsilon can be equipped with pay-Electronic Stability Control and Hill Holder, a 0. 93 g of grip, even if the rolling is accentuated by the soft suspension calibration.

Stability of the weaponized agent ( ability of the agent to retain its infectivity and virulence after a prolonged period of storage ) may also be desirable, particularly for military applications.

Stability is the ability of an explosive to be stored without deterioration.

The aim is for this data to be analyzed and shared among regulators – including the newly created Financial Stability Oversight Council – and for the SEC to report to Congress on how the data is being used to protect both investors and market integrity.

Pepsin may be inhibited by high pH ( see " Activity " and " Stability ", above ) or by inhibitor compounds.

In particular, it is possible to relate the spectrum of primary operators in a theory to the value of the central charge, c. The Hilbert space of physical states is a unitary module of the Virasoro algebra corresponding to a fixed value of c. Stability requires that the energy spectrum of the Hamiltonian be nonnegative.

The system has been tested and has also proven to be a useful tool to consolidate / collect data for the Afghan Country Stability Picture ( ACSP, see info box 3 ).

Stability means they vow to stay in that single monastery for the remainder of their lives, and, upon death, will be buried " on-campus ".

Stability is another problem associated with such high gain circuits due to any unintentional positive feedback that may be present.

' Stability ' should not be confused with reactivity.

Safety devices such as Electronic Stability System that prevent the sidelifter from rolling over may be sometimes required by local legislations

Some vehicles are equipped with a Trailer Stability Program that may be able to compensate for improper loading.

Electronic Stability Control must also be at least optional.

Stability analysis shows that the planet's Lagrangian points would be stable enough to host Earth-sized planets, though as yet no trojan planets have been detected in this system.

Stability analysis reveals that the orbits of Earth-sized planets located in the planet's trojan points would be stable for long periods of time.

Stability and performance were improved by Mac OS 7. 6, which dropped the " System " moniker.

Stability issues, together with a dispute between Linn and Lombard, led Linn to create the Linn Manufacturing Company, builder of the Linn tractor, for building and putting onto the market his own improved civilian halftrack-style machines.

Stability was improved, but acetabular wear and subsequent failure rates were increased with these designs.

In the United States the safety structure was improved and Vehicle Stability Control made standard.

The Super-Select 4WD II system was retained, complemented by an improved Active Stability & Traction Control ( ASTC ) system and electronic brakeforce distribution.

The Conference on Security, Stability Development and Co-operation in Africa ( CSSDCA ) is a policy development process created to function within the framework of the African Union and was adopted at the 36th Session of the Assembly in Lomé, Togo on July 2000.

Ford later added Roll Stability Control to AdvanceTrac which was first introduced in Volvo XC90 in 2003 when Volvo Cars was fully owned by Ford and it is now being implemented in many Ford vehicles.

An on-road system, Dynamic Stability Control ( DSC ) prevented skidding when steering and braking at speed.

Because the Tundra's Vehicle Stability Control system is disabled when the vehicle's 4x4 system is engaged Consumer Reports has questioned the Tundra's Top Safety Pick award.

Stability eluded him again, however, when Longley became rivals with Lay's nephew for the affections of a young woman.
