The aim of study was the examination of the median branches (MB) of the basilar artery (BA). 783 MB were found in 100 human brainstems injected with coloured latex. The attachment of the MB to the quadrants of the BA's trunk, their structural shape, length of trunks, topographical arrangement (on three vascular levels) and the clinical importance of this vascular pattern was evaluated. The MB a...

An algorithm of generating navigation path in orchard for harvesting robot based on machine vision was presented. According to the features of orchard images, a horizontal projection method was adopted to dynamically recognize the main trunks area. Border crossing points between the tree and the earth were detected by scanning the trunks areas, and these points were divided into two clusters on...

Association of phytoplasma with quick decline of macadamia trees in Hawaii was reevaluated. Twenty samples were collected from symptomatic and symptomless trees of the two susceptible cultivars cv. 333, and cv. 344 grown at Keaau and Kaiwiki on the island of Hawaii. Ultrasensitive nested-PCR assays using two universal primer pairs failed to detect phytoplasmas in all samples tested, contradicti...

During treatment of tumors of nerve sheaths, such as schwannomas and neurofibromas, neurosurgeons should be aware of variations and aberrant formations of brachial plexus. Variations of the branches of brachial plexus are common, but its variations in the level of the roots and trunks are rare. Variations regarding lower trunk were founded more frequent in previous studies. An unusual variant o...

1. the oesophageal plexus is in the structure and arrangement of its larger branches constant. ·2 . two trunks arise from the oesophageal plexus, the . anterior vagal trunk and the posterior vagal trunk; each trunk contains fibers of both left and right vagi nerves. 3. these vagal trunks in the majority of instances pass through the oesophageal opening of the diaphragm each in the form of the o...

Aims. The radiation from newly born stars photoevaporates their parental neutral cloud, leading to the formation of dense clumps that will eventually form stars. Methods. We present 3D simulations of the interaction of a neutral cloud with an external ionising radiation field, and compute the angular momenta of these collapsing clumps. Results. The angular momenta of these collapsing clumps sho...
