Thinning is one of the intensive forest management techniques commonly applied to increase the merchantable timber volume. However, how thinning affects soil–atmospheric fluxes of greenhouse gases (GHGs) is poorly understood. A field experiment with four treatments (CK: unthinned; MB: medium intensity thinning from below; HB: high intensity thinning from below; and HI: high intensity thinning b...

The absolute and relative effects of the fi rst thinning on the diameter growth distribution along the stems were studied in 98 Scots pines (Pinus sylvestris L.) at heights of 1.3, 4, 6 and 8 m. The data cover one 3-year pre-thinning period and four 3-year post-thinning periods in plots with densities varying from 575 to 3400 stems ha–1. A shift in the point of maximum diameter growth down the ...

In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...

Thinning is the important technique used in the image processing. The first step in the Thinning is “PreProcessing”. This Thinning technique is used to represent the structural shape of the image. This thinning technique is used to compress the image and also to display the skeleton of the image. Skeletonization is a process of reducing foreground regions of a binary image to a skeleton form th...

Background: As the decomposition of lignocellulosic compounds is a rate-limiting stage in the nutrient mineralization from organic matters, elucidation of the changes in soil enzyme activity can provide insight into the nutrient dynamics and ecosystem functioning. The current study aimed to assess the effect of thinning intensities on soil conditions. Un-thinned control, 20 % thinning, and 30 %...

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...

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...
