An efficient method for the continuous extraction of subway tunnel cross sections using terrestrial point clouds is proposed.First, the continuous central axis of the tunnel is extracted using a 2D projection of the point cloud and curve fitting using the RANSAC (RANdom SAmple Consensus) algorithm, and the axis is Gloves optimized using a global ex
Expression of CD 68, CD 45 and human leukocyte antigen-DR in central and peripheral giant cell granuloma, giant cell tumor of long bones, and tuberculous granuloma: An immunohistochemical study
Background: Multinucleated giant cells (MNCs) form an integral part of numerous bone and soft tissue tumors, tumor-like lesions and are often associated with granulomas of immunological and nonimmunological origin.The presence of various types of giant cells depends on the lesions in which they are present which are difficult to be diagnosed under
Pelargonic acid for weed control in onions: factors affecting selectivity
In onions (Allium cepa) few herbicides are registered.Due MORE MILK PLUS SPECIAL BLEND to their erect leaf and plant structure, onions retain less herbicide after spraying than broadleaved weeds.Further, onion plants have a thicker plant cuticle.These differences allow a selective use of pelargonic acid in onions.The main aim of this study was to d
