Vertebral artery aneurysm rupture is a rare cause of sudden death. The presented case was 31-year-old woman who was found dead in her bedroom. Family members stated that she had history of one year duration childhood epilepsy treatment. Autopsy investigation revealed 5 mm in diameter aneurysm, ruptured in 1 mm area, localized on the trunk of the right vertebral artery. We described an autopsy c...

PURPOSE To determine the normal anatomic features and variations of the internal mammary arteries (IMAs) and to describe the relationship between the diameter and distance to the sternal edge of the IMAs, gender, and location (right-left) of the IMAs in patients who underwent multidetector computed tomography (MDCT) angiography of the thorax for various reasons. MATERIALS AND METHODS A total ...

Pratylenchus vulnus suppressed the growth of sour orange seedlings in greenhouse experiments. Growth retardation (in height, in trunk diameter, and in dry top and root weights) was observed in inoculated plants growing in two soil types. Population density, 13 months after inoculation, averaged more than 1,000 specimens/gm of fresh root. Anatomical studies showed that P. vulnus prefers to attac...

At surgery, a fistula with an external diameter of 1 mm was identified between the anterior interventricular artery and the pulmonary trunk, with a shunt toward the pulmonary artery tree. The fistula was disconnected with suture. The anomalous origin of the coronary artery was not detected. As a result, the systolic murmur disappeared and the electrocardiogram showed a normal ventricular repola...

[1] Hydraulic resistance of riparian forests is an unknown but important term in flood conveyance modeling. Lidar has proven to be a very important new data source to physically characterize floodplain vegetation. This research outlines a recent campaign that aims to retrieve vegetation fluid resistance terms from airborne laser scanning to parameterize trunk roughness. Information on crown cha...

The importance of urban forests is undeniable when considering their benefits to the environment, such as improving air quality, landscapes and breaking its monotony. However, trees are subject failures that can cause personal economic damage. Therefore, it necessary know health conditions define most adequate management. Some tools used detect plant conditions, visual analysis, tomography, dri...

It was found that the ductus arteriosus is a muscular channel and resembles the muscular artery in structure. The diameter of the ductus is equal throughout its length. At the orifice of the ductus to the aorta the cells of its wall blend with those of the aorta. The primordia of the tunica media of the aorta and the pulmonary trunk consist of regularly arranged, circular layers which are more ...

Trunk diameter is a variable of agricultural interest, used mainly in the prediction of fruit trees production. It is correlated with leaf area and biomass of trees, and consequently gives a good estimate of the potential production of the plants. This work presents a low cost, high precision method for the measurement of trunk diameter of grapevines based on Computer Vision techniques. Several...

Quantifying carbon in agroforestry trees requires biomass equations that capture the growth differences (e.g., tree specific gravity and architecture) created in the more open canopies of agroforestry plantings compared with those generally encountered in forests. Whereas forest-derived equations are available, equations for open-grown trees are not. Data from destructively sampled open-grown t...

carbon sequestration into plants biomass, especially in fast growing trees is an easier and economically way for dropping off co2 from atmosphere. this study was carried out in order to investigate above-ground biomass of white poplar (populous alba, l.) plantations that was planted in fourdifferent plant spacing (0.5 × 0.5, 1×1, 2×2 and 4×4 m.) in chaharmahal and bakhtiari province in west of ...
