The distance from the cloaca to the posterior margin of the carapace appears to be the most effective measurement for sexing turtles of this size among the six characteristics investigated. In the sample, females are estimated to comprise 61% of the specimens >75 cm. 展开 ...
skull base showed that the mean values of all measurements were significantly higher in males than females except for Maxillo-Alveolar Index was not significant and also showed that the size of the palate was the best indicator for sex variation and making the diagnosis of male with accuracy ...
Four techniques for measuring the spot size of a single-mode fiber are compared for accuracy and ease of use. The techniques are based upon imaging of the fiber near fields onto an infrared vidicon, measuring splice loss sensitivity to transverse offset, approximating the fiber far-field radiation...
Outside Io's orbit, the plasma densities observed by Galileo are approximately a factor of two higher than the Voyager values. Shortly after crossing Io's orbit, the Galileo density profile dropped sharply and remained at low values for the rest of the inbound leg, suggesting that the '...
The large liquid scintillator method has been used to measure the energy dependence of v ¯ p for 239Pu below 2 MeV. No fine structure in the low energy region was observed. An analysis of all existing 239Pu v ¯ p data below 5 MeV suggests a two-line energy dependence with a chan...
摘要: Cross sections for (p,n) transitions to analog states for targets of Ta, Au, and Bi have been measured. The cross section and decay width observed for Bi are inconsistent with those obtained from (p,np) measurements. We propose an explanation for these discrepancies....
crime prevention measurements of university students is also a complicated systematic project,according to the concrete causes of crime The preventing measures should include: strengthening school education for a healthy mental quality,good moral quality and the legal ideas,strengthening family education,and...
Initial three-dimensional phase and intensity measurements of a 100 GHz l=±1 orbital angular momentum (OAM) vortex are presented. The vortex was generated by illuminating a polypropylene spiral phase plate. Measurements were taken with a three-dimensional field scanner operating in the W-band (75...
This paper describes the metrological research and dissemination work carried out in the viscosity field at the Istituto di Metrologia "G. Colonnetti" (IMGC) of the National Research Council of Italy, which is responsible for national standards of mechanical and temperature units. Emphasis is given...
The amplitude-attenuation and phase-shift of directional electromagnetic propagation measurements-while-drilling are computed via the magnetic-current-source dyadic Green's functions for horizontally stratified anisotropic media.The detection range and the sensitivity to formation boundaries of directional electro...
