seed loss at harvesting time is one of the factors reducing seed yield in at farms. this study was carried out within a research farm in karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. the experiment was split-plot based on randomized complete...

We report the first three-dimensional photonic metamaterial, an array of erected U-shape plasmonic gold meta-molecules, that exhibits a profound response to the magnetic field of light incident normal to the array. The metamaterial was fabricated using a double exposure e-beam lithographic process. It was investigated by optical measurements and finite-element simulations, and showed that the m...

Neruchella eichwaldi gen. et sp. nov. is erected on the basis of a head shield found in Famennian Lebedyanian Regional Stage Orel Region, Russia. The new taxon differs from all known ptyctodontids, and characterized by central plates contact along skull midline, meeting sensory-line canals centrals loss nuchal plate. structures shields two ptyctodontids Chelyophorus are completely different gen...

Both sexes of Nilotonia sketi sp. nov. are described from percolating water of a cave in Cat Ba island in Halong Bay, Vietnam. The IV-L-6 of the new species is characterized by a line of longer ventral setae, and presence of two longer distoventral setae. The systematic position of Nilotonia species attributed to the subgenera Dartiella K. Viets, 1929 and Dartonia K. Viets, 1929 are discussed. ...

Within the context of ongoing taxonomic revisions of terrestrial flatworms from Australia and the Subantarctic Islands of New Zealand: (1) a new subfamily of the Terricola, the Anzoplaninae, is erected, and some subantarctic terricolan taxa are reassigned to the new subfamily; (2) diagnoses for the subfamily Caenoplaninae and genus Coleocephalus are emended; (3) the new genera Anzoplana and Fyf...

If equilateral triangles are erected outwardly on the sides of any given triangle, then the circumcenters of the three erected triangles form an equilateral triangle. This statement, known as Napoleon’s theorem, and the configuration involved, usually called the Torricelli configuration of the initial triangle, were generalized to d-dimensional simplices (d ≥ 3) in [12]. It is obvious that for ...

Published in 2020, The Belgorod Line. History. Fortification. People, a book by Andrey Papkov, Nikolay Petrukhintsev, and Dmitry Khitrov is the first attempt to understand update modern achievements studying authors reveal historical specifics behind construction of this military-defensive line broad context seventeenth century. They show background events (before 1635), building process, socia...
