Related to cross section: Scattering cross section

cross sec·tion

1. a planar or two-dimensional view, diagram, or image of the internal structure of the body, part of the body, or any anatomic structure afforded by slicing, actually or through imaging (for example, radiographic, magnetic resonance, or microscopic) techniques, the body or structure along a particular plane. Traditionally, "cross section" referred to views resulting from slicing at right angles to the longitudinal axis of the structure (axial or transaxial), but in contemporary use, the term is applied when the structure is sliced in any given plane;
2. the slice or section of a given thickness created by actual serial parallel cuts through a structure or by the application of imaging technique.

cross section

A section perpendicular to the long axis of an organ.

In this regard, demonstratively executed on the basis of the mathematical relations (2) and (3), taking into account the nonlinear change in the specific electrical conductivity [[gamma].sub.i] of the material of the cores (shells) of the CCP during its Joule heating by SC current [i.sub.k(t)], the calculation refinement of numerical values for the coefficient [C.sub.ik], directly used to determine by (1) the permissible cross sections [S.sub.il], is an electrotechnically justified and expedient action.
Based on (19) and (20), parabolic and linear tendons are designed, and the position of the strand, relative to the neutral axis in each cross section, is shown in Figure 5.
Figure 4 gives the scattering and absorbing cross sections of feldspar particles.
Using the proposed approach we have found that the strain softening effect exhibited by the concrete in compression indicates lower bending capacity of cross section and also "snap-back" behaviour of the moment-curvature response; this effects are more accentuated as degree in confinement is decreased.
In another prescription of photon isolation proposed by Frixione [97], the fragmentation components are suppressed while the cross section is kept infrared safe at any order in perturbative QCD.
The parameters were adjusted from their original values as shows in table 3 (Hint: We select the energy at maximum cross section for different reactions for selected isotopes).
Georgia Tech's cross section values can now be used by scientists attempting to find water throughout the solar system and beyond.
So there is a need for measuring the scattering cross sections at forward angles using a different experimental method involving minimum corrections.
The total extinction coefficient, a=[sigma]N, was expressed as a product of the total extinction cross section, [sigma], in units of [cm.sup.2] and the concentration of microspheres, N, in units of [cm.sup.-3].
In order to reduce the wrinkling risk and cross section deformation degree, it is considered to fill the tube with fine sand, fluid, or rosin-cerate [3].
Hollow core circular concrete members are much less structurally used than solid circular cross sections. Though, these can be found in concrete chimneys, concrete pipes and elevated water tanks, as well as in large bridge columns and offshore platforms (Turmo et al.
