It seems likely that the particular choice of scale simply came about as a result of manually matching the target page size and the area to be covered by the
graticule. The true scale parallel ([[phi].sub.1] in Eq 2) is estimated to be 31.88[degrees]N.
Sections were examined by using calibrating ocular
graticule for the number and diameter of primary, antral and atretic follicles and number and size of the ovarian cysts, by the method described earlier.14 Follicles were counted and classified according to a previously published method.15
Inter-nuclear distances were calculated with the help of linear
graticule. The number of divisions was counted on linear
graticule mounted on ocular micrometer and was multiplied with calibration factor.
The 50m scale
graticule in the bottom right corner of Figure 2 was about 1.75cm long, and from this I deduced that the distance between the image of the plane and the image of its shadow was 14.40/1.75 x 50 [approximately equal to] 411m.
All the illustrations were made by ocular
graticule Stereo-Binocular microscope.
For this purpose, the necrotic surface area was estimated by using
graticule (Olympus, Japan) on tumor slides.
Volumetric ratios of the components of the testicular parenchyma were established by the point counting method at 400x magnification using an optical microscope fitted with a 121-point eyepiece
graticule. For each animal, points corresponding to the seminiferous tubules (germinal epithelium, tubular lumen and spermatozoids) and the intertubular compartments (connective tissue, blood and lymph vessels, Leydig cells) were counted in twenty randomly distributed fields.
One of the most popular new features in Surfer 13 is the ability to display latitude/longitude
graticule lines over a projected map, allowing users to view their maps and data in various coordinate units.
The height of 10 well orientated villi and their adjoined crypts were measured with a light microscope using a calibrated eyepiece
graticule and a computer-assisted, image-analysis system (Pluske et al., 1996).
An important feature of the tube is that the electron beam is intercepted by a flat mica sheet, one side of which is coated with a fluorescent screen and the other side of which is printed with a centimetre
graticule so the electron path is easily traced.
Tumor measurements are usually performed as a visual estimate or with a ruler or an ocular micrometer on the side
graticule. The knowledge of the diameter of the field at each magnification for the microscope used to measure tumor extent can also help maximize accuracy of a visual estimation of length.
Using a Weibel
graticule (WEIBEL, 1963; LOWE; MOORE, 1985) coupled to the microscope objective and using the 40 x lens, 10 fields were randomly chosen per slide per animal.
ED-1-positive cells in tubulointerstitium were counted in 25 consecutive high power (x400) interstitial fields by means of a 0.02 [mm.sup.2]
graticule fitted in the eyepiece of the microscopy and expressed as cells/[mm.sup.2].
A dissecting stereo microscope with eyepiece
graticule (units 1-100 m) was used; measurements were taken through the right eyepiece only to avoid distortion from change of angle (Peck, 2009).
New agreement in assessing vertical cup:disc ratio using 78D lens with slit lamp eyepiece measuring
graticule. Yan Ke Xue Bao 2007;23:53-7.15.
