extension

 [ek-sten´shun]
1. the movement by which the two ends of any jointed part are drawn away from each other.
2. a movement bringing the members of a limb into or toward a straight condition.
Buck's extension a temporary type of lightweight traction applied to the distal end of a fractured lower limb; the foot of the bed is raised so that the body makes counterextension; often used to reduce muscle spasm.
Buck's extension.
nail extension extension exerted on the distal fragment of a fractured bone by means of a nail or pin driven into the fragment.

ex·ten·sion

(eks-ten'shŭn), [TA]
1. The act of bringing the distal portion of a joint in continuity (although only parallel) with the long axis of the proximal portion.
2. A pulling or dragging force exerted on a limb in a distal direction.
3. The movement produced by contraction of one or more extensor muscles; it generally results in the straightening of a limb; axial traction that generally lengthens a limb or straightens the trunk; the opposite or antagonistic movement of flexion.
4. Obsolete term for traction.
[L. extensus, past part. of extendere, to stretch out, extend]

(ĭk-stĕn′shən)
n.
1.
a. The act of straightening or extending a limb.
b. The position assumed by an extended limb.
2. Medicine The application of traction to a fractured or dislocated limb to restore the normal position.

Here [[eta].sup.+.sub.e](t) is the transient extensional viscosity, [[eta].sub.k] = [G.sub.k][[lambda].sub.k], where [G.sub.k] is the strength of Mi relaxation mode and [[lambda].sub.k] is the kth relaxation time as obtained from the DRS, and [??] is the strain rate applied in the experiment.
Al utilizar la nocion de verdad de Tarski, se tiene una formulacion de la teoria totalmente extensional, ya que al acudir a tal nocion, como base de la construccion de la teoria, se evita de una manera satisfactoria acudir a expresiones de tipo intensional.
At the center of the Sichuan basin the increased thickness of Early Cambrian strata is consistent with overlain extensional faults in pre-Cambrian strata in the Gaoshiti-Moxi area (Figure 2).
In the northern part of the CV faults trend mainly N-S, while the E-W- to ENE-WSW-trending faults are interpreted to be transfer zones forming part of a generalized extensional system of N-oriented faults, which, as in the Cordillera Frontal, include other orientations (Heredia et al., 2012).

But properly designed extensional shear devices have the potential to reduce screw length while increasing the effectiveness of mixing and melting.
In Example 2 we show that structure ([End.sub.[not equal to]](A, [=.sub.A], [[not equal to].sub.A], [cross product]), =, [not equal to], [omicron], [??]) of all strongly extensional endomorphisms of semigroup (A, [=.sub.A], [not equal to][.sub.A], *) with apartness is a semilattice-ordered semigroup with apartness.
Historically, extensional viscosity measurements have been done on polymer melts and concentrated solutions with homemade instruments.
A fin de visualizar las diferentes geometrias asociadas con estructuras invertidas que actuan como potenciales trampas estructurales y entender mejor la interaccion entre la tectonica extensional y contractiva que afecta series meso-cenozoicas durante el proceso de inversion tectonica en la region, se consideraron como guias importantes a los reflectores sismicos asociados a la discordancia del Eoceno, al tope del Cretacico Tardio, al tope del Cretacico Temprano, y al Tope del posible basamento Jurasico (Figura 4).
Extensional properties of polymers are also critical in co-extrusion processes--recent research by Zatloukal et al (2) using two identical polymers in a co-extrusion process has shown that interface instabilities can be generated by exceeding critical extensional rates, and that such instabilities can be predicted using rheometry and simulation.
The number average molecular weight and the weight average molecular weight of the blends were calculated (equations (3) and (4)), along with the uniaxial extensional viscosity (Table 2).
