A vector field, varying from point to point, is not always easily represented by a diagram, and it is often helpful for this purpose, as well as in mathematical analysis, to introduce the potential ϕ, from which E may be deduced.
In the apparatus, a helium-gas-filled alfa-type Stirling refrigerator uses Gd sheets as the regenerator and the regenerator is put in a magnetic field varying from 0 to 1.4 T, which is provided by a Halbach-type rotary permanent magnet assembly.
Briefly, the NCAR-CAM3.5, CAM4-Oslo, CAM5.1, GISS model E, GMI, GOCART, HADGEM2, IMPACT, INCA, ECHAM5-HAM, OsloCTM2, and SPRINTARS models produced BC MMR fields with resolutions varying from 1.1° × 1.1° to 5.0° × 4.0° (average = 2.6° × 2.0°) and between 19 and 72 vertical levels (average = 40).
Visual fields can be impaired, varying from partial visual field defects, to severe constriction of visual fields [ 16].
We were interested only in the T2-weighted sagittal slices of the lumbar spine (slice thickness of 4 mm, matrix of 512 × 512 and field of view varying from 320 × 320 mm2 to 400 × 400 mm), in which the nucleus zone can be differentiated from the annulus zone using the segmentation of the high signal intensity zone.
Its versatility is illustrated using results obtained from experiments carried out at scales varying from field to farms to landscape.
The magnetic field has been increased in steps from the gun and over the first five magnets varying from Brillouin field (BB) value to twice BB for achieving the electron beam with scalloping less than 10%.
Households are registered and visited regularly by lay field-workers, with a frequency varying from once per year to several times per year.
Particle image velocimetry (PIV) was used to obtain the instantaneous, two-dimensional velocity field for grid Reynolds number, Reg, varying from 1080 to 10,800.
