- Polar effect
for polar effect in genetics polar effect genetics The Polar effect or electronic effect in chemistry is the effect exerted by a substituent on modifying electrostatic force s operating on a nearby chemical reaction reaction center. The main contributors to the polar effect are the inductive effect , mesomeric effect and the through space electronic substituent field effect field effect . An electron withdrawing group or EWG draws electrons away from a reaction center. When this center is an electron rich carbanion or an alkoxide anion with the presence of the substituent that has a stabilizing effect. Examples of electron withdrawing groups are halogen s F, Cl nitrile s CN carbonyl s CO Nitro compound nitro groups NO2. An electron releasing group or ERG otherwise called electron donating groups or EDG releases electrons into a reaction center and as such stabilizes electron deficient carbocation s. Examples of electron releasing groups are alkyl groups alcohol groups amine amino groups. The total substituent effect is the combination of the polar effect and the combined steric effect s. In electrophilic aromatic substitution and nucleophilic aromatic substitution substituents are divided into activating group s and deactivating group s where the direction of activation or deactivation is also taken into account.

- Mesomeric effect
Seealso Resonance chemistry File Mesomeric effect M V.1.png thumb right 600px M effect of a methoxy group in an ether File Mesomeric effect M V.1.png thumb right 420px M effect of a carbonyl group in acroleine The mesomeric effect or resonance effect in chemistry is a property of substituent s or functional group s in a chemical compound . The effect is used in a qualitative way and describes the electron withdrawing or releasing properties of substituents based on relevant resonance structure s and is symbolized by the letter M . The mesomeric effect is negative M when the substituent is an electron withdrawing group and the effect is positive M when based on resonance and the substituent is an electron releasing group. Examples of M substituents acetyl IUPAC ethanoyl nitrile Nitro compound nitro Examples of M substituents alcohol amine benzene The net electron flow from or to the substituent is determined also by the inductive effect . The mesomeric effect as a result of p Atomic orbital orbital overlap resonance has absolutely no effect on this inductive effect, as the inductive effect is purely to do with the electronegativity of the atoms and their topology in the molecule which atoms are connected to which . The concepts of mesomeric effect, mesomerism and mesomer were introduced by Christopher Kelk Ingold Ingold in 1938 as an alternative to the Linus Pauling Pauling s synonymous concept of resonance effect resonance . ref If It s Resonance, What Is Resonating? Kerber, Robert C. . J. Chem. Educ. 2006 83 223. http www.jce.divched.org Journal Issues 2006 Feb abs223.html Abstract ref Mesomerism in this context is often encountered in German and French literature but in English literature the term resonance dominates. Mesomerism in conjugated systems Mesomeric effect can be transmitted along any number of carbon atoms in a conjugated system . This accounts for the resonance stabilization of the molecule due to delocalization of charge. See also List of publications ... more details

- Accordion effect
orphan date January 2010 In non linear physics , the accordion effect occurs when fluctuations in the motion of a travelling body causes disruptions in the flow of elements following it. This can happen in traffic road traffic , foot march ing, bicycle racing , and, in general, to processes in a pipeline transport pipeline . This effect generally decreases the throughput of the system in which it occurs. The accordion effect is known by various aliases such as the slinky effect or the Concertina effect , and the string instability.

- Ramp effect
Unreferenced date December 2009 Orphan date December 2009 The ramp effect or ramping effect is a phenomenon involved in drug addiction whereby an addict develops a resistance to a substance, and thus requires increasingly large quantities of that substance to achieve the same effect. This can lead the addict to exponential growth rapidly increase their dosages, which can lead to a variety of health maladies. After the ramp effect has begun, it may be very difficult to deprive an addict of their substance, or even to reduce the dosage. Much of drug rehabilitation consists of resisting and reversing the ramping effect.

They do not use trick photography or post production artifice. This type of effect is normally found in live theatre . In film , practical effect denotes an effect produced on set, without computer generated imagery . Special effect is often synonym ous with practical effect . In contrast, visual effects are created in post production through photographic manipulation or computer generation. Many of the staples of action movies are practical effects. Gunfire, bullet wounds, rain, wind, fire, and explosions can all be produced on a movie set by someone skilled in practical effects.
