INTRODUCTION The use of Top Coal Caving for exploiting the thick coal seam with shallow buried depth most likely has a strong negative impact on the stability. CASE DESCRIPTION Anjialing No. 1 Underground Mine is located in Shuozhou City, Shanxi Province of China. The 4# Coal Seam of this coal mine is the thick coal seam with shallow buried depth, which has the thickness of 12 m and the depth...

This study was aimed at determining major accessory fissures (MAF) and absence or incompleteness of lobar or major fissures (MF) during routine forensic autopsies. Prior to starting this prospective study, forms were prepared to collect data on pulmonary lobes and fissures. In this study, 420 lungs of 210 autopsy cases were examined for incompleteness and absence of MF and complete accessory fi...

UNLABELLED The penetration of a sealant into the tooth fissures can establish longer retention time for a pit and fissure sealant restoration. AIM This in vitro study was to evaluate the penetration ability of two low-viscosity resin materials, a composite and a compomer, applied with and without their bonding agents in comparison to an unfilled resin sealant. METHODS Forty premolars with s...

Lungs are separated into lobes by fissures, with three lobes on the right and two on the left. The fissures facilitate the uniform expansion of the whole lung. The anatomical knowledge of the fissures and the lobes of the lung is important for accurate interpretation of bronchopulmonary segments on X-rays and CT scans. 40 pairs of lungs removed from cadavers were utilized for the study of the p...

Segmentation of lung anatomical parts like fissures and bronchopulmonary segments are of clinical importance in interpreting and assessing the pathologies present in the lungs. Segmentation of fissures still remains a challenging task as the selection of the segmentation algorithm decides the accuracy of the fissure segmentation. We conducted experiments on the existing segmentation methods and...

Background: The fissures in lung enhance uniform expansion. These fissures may be complete, incomplete or absent. A detailed knowledge of variations of classical and accessory fissures is necessary for proper radiological interpretation. It is a guide to cardiothoracic surgeons performing segmental lung resections, lobectomies to have an uncomplicated perioperative outcome. So, the cadaveric st...

The layered cortex of the cerebellum is folded along the anterior-posterior axis into lobules separated by fissures, allowing the large number of cells needed for advanced cerebellar functions to be packed into a small volume. During development, the cerebellum begins as a smooth ovoid structure with two progenitor zones, the ventricular zone and upper rhombic lip, which give rise to distinct c...

Artificial fissures were inserted in 3 subjects for 1-21 days. At a salivary concentration of lo3 colony-forming units (CFU) Strep. mutans@, fissures were colonized by this organism. The proportional distribution of Strep. mutans increased with time and comprised up to 6 per cent of the total number of organisms in the fissure at day 21. The total number of organisms in the fissure did not incr...
