A 21 ac, 28-yr-old water oak (Quercus nigra L.)plantation, on an old-field loessial site in north Louisiana, was subjected to three thinning treatments during the winter of 1987-1988: (I) no thinning, (2) light thinning to 180 dominant and codominant trees/at, and (3) heavy thinning to 90 dominant and codominant trees/at. Prior to thinning, the plantation averaged 356 trees/at and 86@/ac of bas...
Non-selective thinning of a hybrid aspen coppice stands via corridor or cross-corridor cutting impacts residual trees differently depending on their competitive status. Suppressed trees’ metabolic profile indicates increased stress level, especially after thinning. Early with regular harvests is proposed for the management post-harvest re-sprouted (Populus tremula L. × P. tremuloides Michx.) st...
We study the pinch-off dynamics of droplets of yield stress and shear thinning fluids. To separate the two non-Newtonian effects, we use a yield stress material for which the yield stress can be tuned without changing the shear thinning behavior, and a shear thinning system (without a yield stress) for which the shear thinning can be controlled over a large range, without introducing too much e...
Importance Measurement of the rates of retinal nerve fiber layer (RNFL) thinning has consisted primarily of the circumpapillary RNFL profile. This study reports the rates of RNFL thinning over the 6 × 6 mm2 RNFL thickness map and their application for indication of visual field (VF) worsening in patients with glaucoma. Objective To investigate the association between the rates of RNFL thinnin...
