section (federal code)

A particularly numbered subpart of some federal law.The text of any federal law may be found by going to the Office of the Law Revision Counsel at uscode.house.gov and clicking on “Search the U.S. Code.” Laws written as, for example,“26 U.S.C. Section 121,”“26 U.S.C. §121,”or sometimes “U.S.C.A.”or “U.S.C.S.”consist of a “title”(26 in the example) and a “section”(121 in the example).Entering the appropriate title and section will bring up the text of the law. See also U.S.C.


section (of land)

A section is a specific area of land measuring 1 square mile. See public land survey system.

From the heat balance equation for the current-carrying parts of the CCP of the circuits of indicated electrical installations in the adiabatic mode and the condition of their thermal resistance to current [i.sub.k(t)] of the adopted SC, the analytical expression for the refined calculation determination of the allowable cross sections [S.sub.il] of the considered electrical wires and cables takes the following form [6] :
The Magnel diagram in the maximum bending moment cross section is drawn in Figure 3; the quadrilateral occupies a small region in the coordinate system, and for the designer, it is difficult to spot the centre, and the quadrilateral has been magnified in the figure.
Figure 2 gives the scattering cross sections of spheroid quartz particles with different sizes.
The complete moment-curvatures have been depicted both for strong and weak axis of bending and the plastic status of the cross-section associated to different values of the reference strain imposed in the most compressed point of the cross section has been revealed on the graph.
As mentioned, the photon isolation also significantly reduces the fragmentation components of the prompt photon cross section. Actually, the reason is that the fragmentation photons are emitted collinearly to the parent parton, and on the other hand, the isolation cut discards the prompt photon events that have too much hadronic activity.
They either came off with a cross section of almost 6 x 10-19?cm2 or broke apart with a cross section of almost 5 x 10-19?cm2.
