Clearly, the thermal averaging effect is much less pronounced for the attractive induction and dispersion forces.

Dispersion forces are usually dominant of the three van der Waals forces ( orientation, induction, dispersion ) between atoms and molecules, with the exception for molecules that are small and highly polar, like of water.

The physical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Faraday's law of induction, was discovered by Michael Faraday in 1831.

Simulations have been used that model all biomolecular interactions in transcription, translation, regulation, and induction of gene regulatory networks, guiding the design of synthetic systems.

As a result of these interactions the function of the enzymes can either be stimulated ( enzyme induction ) or inhibited ( enzyme inhibition ).

Thus steric effects are often contrasted and complemented by electronic effects implying the influence of effects such as induction, conjunction, orbital symmetry, electrostatic interactions, and spin state.

Specifically, L is the gas-liquid partition constant on hexadecane at 298 K ; E the excess molar refraction ; S the ability of a solute to stabilize a neighboring dipole by virtue of its capacity for orientation and induction interactions ; A the solute ’ s effective hydrogen bond acidity ; and B the solute ’ s effective hydrogen-bond basicity.

To Popper, science does not rely on induction, instead scientific investigations are inherently attempts to falsify existing theories through novel tests.

As a result, the malignant cells experience an abnormal response to apoptosis induction: cycle regulating genes ( such as p53, ras or c-myc ) are mutated or inactivated in diseased cells, and further genes ( such as bcl-2 ) also modify their expression in tumors.

The ways that ideas and values are communicated within communities are important to the induction of new members, the formulation of agendas, the selection of leaders and many other aspects.

The main classes of chemotaxis receptors are triggered by formyl peptides-formyl peptide receptors ( FPR ), chemokines-chemokine receptors ( CCR or CXCR ) and leukotrienes-leukotriene receptors ( BLT ); however, induction of a wide set of membrane receptors ( e. g. amino acids, insulin, vasoactive peptides ) also elicit migration of the cell.

The exact mechanism by which the corona is heated is still the subject of some debate, but likely possibilities include induction by the Sun's magnetic field and sonic pressure waves from below ( the latter being less probable now that coronae are known to be present in massive, hot, highly magnetic stars ).

Few philosophers are as associated with induction as David Hume ; but Hume himself rarely used the term and when he did, he used it to support a point he was arguing.

A common misconception is that the E and B fields in electromagnetic radiation are out of phase because a change in one produces the other, and this would produce a phase difference between them as sinusoidal functions ( as indeed happens in electromagnetic induction, and in the near-field close to antennas ).

It fails to fully consider the structure and method of mathematical science, the products of which are arrived at through an internally consistent deductive set of procedures which do not, either today or at the time Mill wrote, fall under the agreed meaning of induction.

When considered over a countable language, the completeness and compactness theorems are equivalent to each other and equivalent to a weak form of choice known as weak König's lemma, with the equivalence provable in RCA < sub > 0 </ sub > ( a second-order variant of Peano arithmetic restricted to induction over Σ < sup > 0 </ sup >< sub style =" margin-left :- 0. 6em "> 1 </ sub > formulas ).

Injection anaesthetics are used for induction and maintenance of a state of unconsciousness.

There are an enormous variety of different induction techniques used in hypnotism.

Today the terms inoculation, vaccination and immunization are used more or less interchangeably and popularly refer to the process of artificial induction of immunity against various infectious diseases.

The bottom stratum consists of narrow abilities that are highly specialized ( e. g., induction, spelling ability ).

The principle of coupled magnetic fluxes between a stationary and a rotating inductor coil is also used to produce mechanical torque in induction motors, which are widely used in appliances and industry.

Among these are analogies to physical momentum, to frictional forces and to mathematical induction.

They are sometimes useful for constructing the base case of an induction argument.

In common with other advanced rapid transit systems, some monorails are driven by linear induction motor.

The Penicillium cells are grown using a technique called fed-batch culture, in which the cells are constantly subject to stress, which is required for induction of penicillin production.

More substantially, the terms statistical inference, statistical induction and inferential statistics are used to describe systems of procedures that can be used to draw conclusions from datasets arising from systems affected by random variation, such as observational errors, random sampling, or random experimentation.

Initial requirements of such a system of procedures for inference and induction are that the system should produce reasonable answers when applied to well-defined situations and that it should be general enough to be applied across a range of situations.

Each year, a grass-court tournament and an induction ceremony honoring new Hall of Fame members are hosted on its grounds.

For example, many results about Borel sets are proved by transfinite induction on the ordinal rank of the set ; these ranks are already well-ordered, so the axiom of choice is not needed to well-order them.

This is in accordance with Lenz's law, which states that induction of EMF always opposes development of any such change in magnetic field.

He uses the fact that induction assumes a valid connection between the proposition " I have found that such an object has always been attended with such an effect " and the proposition " I foresee that other objects which are in appearance similar will be attended with similar effects.

Despite many rumours of brainwashing and forced induction into the organisation, Spencer has always maintained that he joined the organisation of his own free will.

A memorable quote from his induction speech at the Hall of Fame goes as follows, " I have always said that George Kell has taken more from this great game of baseball than he can ever give back.

If an induction causes complications during labor, a Caesarean section is almost always conducted.

* Adults selected for the Minisino Honor are almost always crowned ( officially recognized ) immediately following the end of the induction ceremony at the July ( Midsummer ) or August ( Grand ) Rituals.

Prior to 2007, the open-air induction ceremony was always been held the third week of May, though more recently it has depended on the availability of the latest inductees.

The fate of the virus-infected cell is almost always induction of apoptosis through cell-mediated immunity, reducing the risk of infecting neighboring cells.

There is always free electricity in the air and in the clouds, which acts by induction on the earth and electromagnetic devices.

Because Fawcett Stadium only holds 22, 375 fans ( less than half the NFL's minimum requirements for its stadiums ) and the Hall of Fame induction ceremonies bring large numbers of outside fans to Canton, the game has, to date, always sold out ( several NFL teams, as well as the Super Bowl, have similarly enjoyed long sellout streaks ).

An induction generator always operates at the grid frequency irrespective of its rotation speed ; all that is necessary is to ensure that it is driven by the turbine faster than the synchronous speed so that it generates power rather than consuming it.
