This study was carried out to determine the effect of thinning on density, extractives and lignin content of Pinus nigra Amold tree. Wood density was measured with computed tomography and 540+/-20 kg m(-3) were determined on control samples. Density of samples from thinning applied plot was 520+/-20 kg m(-3). The results showed that thinning slightly changes the density of wood and this change ...

The performance of corrugated baffles inserted in a rectangular channel heat exchanger is investigated. The fluid flows and thermal distribution are determined via numerical simulations. The working fluid has a shear thinning behavior. The influence of the baffle design is explored, we interest to the “wavy” shape. The corrugation angle of baffle (α) is changed from 0° (i.e. a straight...

Introduction The semiconductor industry is now facing a major turning point in how to realize the next generation of large-scale integration. Recently 3D integration (3DI) using through-silicon via (TSV) has widely studied and wafer thinning has been considered to be a promising technology for enhancing system performance instead of conventional two-dimensional (2D) scaling due to technical and...

IMPORTANCE Regional left ventricular (LV) wall thinning is believed to represent chronic transmural myocardial infarction and scar tissue. However, recent case reports using delayed-enhancement cardiovascular magnetic resonance (CMR) imaging raise the possibility that thinning may occur with little or no scarring. OBJECTIVE To evaluate patients with regional myocardial wall thinning and to de...

It is a challenging topic to perform pattern reconstruction from a unit-width skeleton, which is obtained by a parallel thinning algorithm. The bias skeleton yielded by a fully-parallel thinning algorithm, which usually results from the so-called hidden deletable points, will result in the difficulty of pattern reconstruction. In order to make a fully-parallel thinning algorithm pattern reconst...

Intensively managed loblolly pine (Pinus taeda L.) plantations often develop nutrient deficiencies near mid-rotation. Common silvicultural treatments for improving stand nutrition at this stage include thinning, fertilization, and vegetation control. It is important to better understand the influence of timing fertilization and vegetation control in relation to thinning as part of improving the...

The advent of optical coherence tomography (OCT) imaging allows identification of the structural contribution of the lamina cribrosa (LC) to glaucoma progression. This study aimed to determine the role of various LC features, such as the LC depth (LCD), LC thickness (LCT), and focal LC defects, on the future rate of progressive retinal nerve fiber layer (RNFL) thinning in patients with glaucoma...

OBJECTIVES To compare different screening procedures for hydroxychloroquine sulfate (Plaquenil) toxicity at different stages of damage. METHODS Ten patients were studied using 10-2 automated fields, multifocal electroretinography, spectral domain optical coherence tomography (SD-OCT), and fundus autofluorescence. RESULTS All 10 patients used hydroxychloroquine for more than 6 years, and tho...
