1. Age-related variations in the horizontal and vertical diameters of the pedicles of the lumbar spine.
- www.arclab.org
- Age-related variations in the horizontal and vertical diameters of the pedicles of the lumbar spine.
- The horizontal and vertical diameters of the pedicles of the lumbar vertebrae were measured from plain anteroposterior radiographs of the lumbar spines of male and female subjects aged from 10 to 65 y. The results showed that there were significant differences between the pedicle diameters of males and females. Horizontal diameters ranged from 7. ... Female vertical diameters ranged from 14. ... 2 mm whilst male vertical diameters ranged from 14. ... Generally, there was a cephalocaudal increase of diameters in both sexes. Significant age-related variations of pedicle diameters were noted at all segmental levels. ... 9 y), the diameters of the 10-14. ... The evidence suggests that pedicle diameters undergo continuous change throughout the age range studied. The changes are characterised by increase of diameters in some age groups and decrease in others, but there was an overall increase of both vertical and horizontal diameters as the age groups were followed from the youngest to the oldest. The pattern of variation with age differed for horizontal and vertical diameters.
2. Motivation for the Survey: APS Diameters
- aps.umn.edu
- Motivation for the Survey: APS Diameters.
- The APS Catalog of the POSS I provides an excellent sample of galaxies for studies of inclination effects on galaxy properties because of the isophotal nature of its diameters. ...
- The Diameter-Inclination effect (first noted by Huizinga 1994 in the ESO-LV), occurs because visual diameters are measured to a deeper isophote for face-on galaxies compared to edge-on galaxies. ... The presence of this effect may have profoundly affected the outcome of several previous studies of the influence of inclination on observed galaxy properties which assumed that the catalog diameters were isophotal. ...
- 1) Are the APS reported major-axis diameters roughly isophotal?.
- If we assume his diameters are isophotal, then the APS major-axis diameters are also isophotal (with considerable plate-to-plate scatter), as shown in Figure 3(a). In fact, the APS E (Red) diameters correspond well to Courteau's 23 mag arcsec^-2 diameters.
- Yes, if we assume the APS diameters are isophotal (as established above), then there is a definite trend of APS to UGC diameter ratio versus ellipticity as shown in Figure 3(b). ... This is the first direct comparison of UGC B band diameters with isophotal diameters in a similar bandpass, and it is a sample of over 5000 cross-identified galaxies. ...
- Use of galaxy catalogs utilizing visual diameters for determination of galaxy diameter functions or to investigate internal extinction in galaxies can lead to erroneous results, especially given the fact that this bias in diameters is inclination dependent.
- This is however based on a 'biased diameter'-limited sample, when true isophotal diameters (obtained using the APS and shown in Figure 4) are used, the sample shows a strong preference for highly-inclined galaxies, counter to the optically thick scenario.

- Diameters derived from the model fluxes assuming e = 1. 0 are compared to 54 occultation diameters and yield an average infrared emissivity e = 0. ... Using this value of e, the diameters, albedos, and thermal beaming parameters are derived for each asteroid using all 3336 observations of 654 asteroids with multiple observations at SNR > 10 in the 12 and 25 micron bands of IRAS. ... The resulting diameters are on average only about 1. 4% larger than the IMPS diameters, however, the derived albedos average 11% smaller. ...

- Shrinking of Apparent Star Diameters.
- The most natural impression is achieved if the apparent star diameters are in the order of the human eye's resolving power of one to two minutes of arc. The best classical projectors had diameters slightly below 10 minutes of arc. With the fiber principle, star projections can have diameters subtending one minute of arc, so that all stars appear as needle-sharp, beaming points.

- Distribution of Ligament Diameters.
- These drop diameters computed by Olesen are nondimensionalized by that ligament radius. Since the liquid disintegrates into multiple ligament sizes, we have to consider a distribution of ligament diameters. Three distributions from statistics (Gaussian, uniform, gamma) were tested to model a distribution of ligament diameters. ...

- In the absence of further information, we might assume that the distribution of ligament diameters is similar to the normal distribution. ...
- As a third modelling distribution for the ligament diameters, the uniform distribution is tested. ...

10. Arrays of ordered Pb nanowires with different diameters
- www.iop.org
- Arrays of ordered Pb nanowires with different diameters in different areas embedded in one piece of anodic alumina membrane.
- Nanochannel arrays with constant nanochannel density but varying nanochannel diameters in different areas in one piece of anodic alumina membrane are achieved. Using this type of membrane as a template, ordered Pb nanowire arrays with constant nanowire density but diameters decreasing radially were obtained by electrodeposition. Scanning electron microscopy and transmission electron microscopy (TEM) images taken from different areas of the Pb nanowire arrays show that we can control the growth of aligned Pb nanowires with different diameters in a single process at one time. ... Nanometre-scale fibrils, rods, wires, and tubules of metal, semiconductor, carbon, and other materials with the same density but different diameters in different areas can be fabricated using this type of template, in combination with other fabrication techniques. The simultaneous integration of ordered nanowire structures with different diameters embedded in a single anodic alumina membrane could be useful in nanodevice manufacture as well as electronics, optoelectronics, and magnetics. ...
