Nodal axon diameter correlates linearly with internodal axon diameter in spinal roots of the cat
Neuroscience Letters, 1981Nodal and internodal axon diameters of individual myelinated nerve fibres were measured electron microscopically in fibre samples from serially sectioned L7 ventral and dorsal spinal root of young adult cats. Axon cross-sectional area at the node of Ranvier in axons more than 4 micrometer in diameter was reduced to less than 20% of its internodal value.

The Diameters Graph of the Root System E 8 is Uniquely Geometrisable
Geometriae Dedicata, 1999A diameter of a root system is a line joining an antipodal pair of roots. The 240 roots of the root system \(E_8\) determine 120 diameters. Any two of these diameters make an angle of sixty or ninety degrees. The diameter graph \(\Gamma\) of \(E_8\) is the graph whose vertices are the 120 diameters of \(E_8\). Two vertices of \(\Gamma\) are adjacent if

Costs and benefits of constructing roots of small diameter
Journal of Plant Nutrition, 1992Abstract Roots represent a considerable carbon cost for plants. Furthermore, plants vary considerably in how carbon is expended for belowground processes. One attribute that varies widely among species is the investment of root biomass in the production of root length.

Practical Equations for Calculating the Root Diameter of Bolts
2020Since bolts can be removed and reassembled, they are often preferred by civil engineers in steel structures. Bolt root (minor) diameter, in other words, the least diameter of the bolt should be considered for most of the bolted connection design. In this case, the designer either takes the root diameter from the tables or calculates it using complex ...

Aortic root diameters in 1043 healthy subjects
2014Purpose: The aim of this study was to explore the full spectrum of aortic root (AR) diameters by two-dimensional transthoracic color-Doppler echocardiography (TTE) in a large cohort of healthy subjects. Methods: From June 2007 to December 2013, 1043 healthy volunteers [mean age 44.7±15.9 years, range 16 to 92; 503 (48%) men] underwent comprehensive TTE.
