The study was designed to evaluate whether the increase in left ventricular (LV) mass in essential hypertensives (H) is associated with a proportional increase in diameter of the left coronary artery (LCA) trunk. Twenty-six hypertensives, 14 with left ventricular hypertrophy (LVH) (left ventricular mass index [LVMI] > or =134 g/m2 in men and > or =110 g/m2 in women) and 12 without LVH, and 10 n...

Accurate vehicle localization in forest environments is still an unresolved problem. Global navigation satellite systems (GNSS) have well known limitations in dense forest, and have to be combined with for instance laser based SLAM algorithms to provide satisfying accuracy. Such algorithms typically require accurate detection of trees, and estimation of tree center locations in laser data. Both...

Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...

PURPOSE To investigate the correlation between optic disc hemorrhages (ODHs) and the position of the central retinal vessel trunk (RVT) in patients with glaucoma. METHODS Fundus photographs of 1,830 participants were reviewed. The exit position of the central retinal vessel trunk was classified as being in the superior or inferior hemisphere of the optic disc and the relative vertical positio...

The maintenance of plane trees (Platanus acerfolia Wild) by regular curtain-like pruning during the vegetative period induced modifications in the distribution and seasonal patterns of carbohydrate reserves in the perennial parts. The unpruned trees were characterized by high and fairly constant concentrations of starch in roots > 5 cm in diameter and a decreasing gradient of starch from the ba...
