Maximum stresses arise at the interface between supporting saddles and cylinder walls, that is in corresponding of the constraint sections, where, in absence of section increments, a stress increase is reasonable.
Previous QTL studies of wood properties have been limited to measurements at single time points or to trait averages of a heterogeneous wood sample (e.g., stem sections, increment cores).
In SRCFT column reinforced with 2 IPE section, the increment in SRCFT columns' strength at the point of deflection about 60 mm is around 75%, compared with the superposed strength of reinforcing steel section and CFT column.
We then compute the eigenvalues of the outer product of the cross-section of increments at the identified jump events.
Image series of 0.75 mm section width, reconstruction increment 0.4 mm, and convolution filter for vessels (I20f) were reconstructed using iterative reconstruction algorithm (SAFIRE, Siemens Healthcare, Forchheim, Germany).
Series of 3 mm section width (reconstruction increment 2 mm) and soft tissue convolution filter (B22f) were performed for subsequent evaluation.
SectionId : a sequentially incremented section number (up to 10) is assigned to each section and inherited at sentence level.
Each field consisted of a stack of 30 optical sections with an increment of 0.3-μm z-separation.
GFB tomogram micrographs were imaged with the section tilted in increments of 1º in a minimum range between -60° and +60° using an Eagle 4096 × 4096 CCD camera (FEI) at 29,000× magnification (0.37 nm/pixel).
The following CT parameters were used: 64 × 0.625 mm collimation, section thickness 2.0 mm, increment of 1.0, 120–140 kVp, and 200 250 mAs.
