A total of 61 pangolin(Manis pentadactyla) burrows at Dawuling Natural Reserve were recorded and measured from June 2000 to May 2001, and 40 of them were dissected. The results indicated that all the burrows were blind without branch. The long diameter of entrance was 14.20 +/- 2.79 cm(n = 61), and the short one was 12.50 +/- 2.83 cm(n = 61). These burrows(More)
The trust region (TR) method is an effective algorithm for image reconstruction of electrical impedance tomography (EIT). Aiming at the drawback of the traditional TR method, an improved method named the nonmonotonic and self-adaptive trust region (NSTR) method is proposed in this paper, in which three kinds of modified techniques are shown that help in(More)
The depressing properties of sodium polyacrylate (PA-Na) for scheelite and fluorite were studied by micro-flotation tests, infrared spectroscopy (IR), zeta potentials, X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). The flotation results reveal that the selective depression effect of PA-Na is better than that of sodium silicate,(More)
OBJECTIVE Previous studies reported a lower platelet count (PC) level and a higher mean platelet volume (MPV) level in severe ischemic stroke. We define MPV/PC as the platelet ratio (PR). This study investigates the relationship between PR and 90-day outcome of large artery atherosclerosis (LAA) stroke. MATERIALS AND METHODS A retrospective analysis was(More)
