Determining the dynamics and sustainability of human interactions with threatened species is essential to inform evidence-based conservation, but data can be challenging collect across large areas multiple user groups. Chinese giant salamanders Andrias spp. are critically depleted China. Wild populations were exploited during 20th century, more recently support a large-scale farming industry. H...

We prove NP-hardness of a wide class of pushing-block puzzles similar to the classic Sokoban, generalizing several previous results [5, 6, 9, 10, 15, 17]. The puzzles consist of unit square blocks on an integer lattice; all blocks are movable. The robot may move horizontally and vertically in order to reach a specified goal position. The puzzle variants differ in the number of blocks that the r...

in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...

OBJECT In this paper the authors correlate the surgical aspects of deep median and paramedian supratentorial lesions with the connective fiber systems of the white matter of the brain. METHODS The cerebral hemispheres of 10 cadaveric brains were dissected in a mediolateral direction by using the fiber dissection technique, corresponding to the surgical approach. CONCLUSIONS This study illum...
