21. Bernardes 2012 studied the cross sectional area of levator ani in 58 women with stage II pelvic organ prolapse. 22. Figure 3 shows a cross sectional view of a single row of reciprocal lattice rods filling of the diffraction conditions. 23. The superstructure comprises twin precast concrete box girders with a fish belly cross sectional shape, identical to the approaches. 24. The skin effect decreases the cross sectional area in which the current travels through the conductor as AC frequency increases. 25. This decreased area causes the resistance to rise due to the inverse relationship between resistance and conductor cross sectional area. 26. This may not necessarily be the cross sectional area of the vehicle, depending on where the cross section is taken. 27. Cross sectional area, as well as " n "', will likely vary along a natural channel.28. Overtone flute tubes typically have relatively long cross sectional area, which encourages the instrument to resonate in the higher harmonics. 29. An aluminium wire must have 1.6 times the cross sectional area as a copper wire to achieve comparable resistance. 30. ECAE is unique because significant cold work can be accomplished without reduction in the cross sectional area of the deformed workpiece.
