A calcisponge fauna occurs in uppermost Permian Conodont Clarkina meishanensis yini zone of the sequence exposed in the vicinity of Laibin, Guangxi Zhuang Autonomous Region, southern China.The fauna is dominated by one thalamid species, Amblysiphonella vesiculosa Stencil and Cookie Cutter Sets de Koninck, 1863, and one new sclerosponge genus and sp
In this paper, we Adapters develop some stationary iterative schemes in block forms for solving double saddle point problem.To this end, we first generalize the Jacobi iterative method and study its convergence under certain condition.Moreover, using a relaxation parameter, the weighted version of the Jacobi method together with its convergence ana
Teratomas are bizarre neoplasms that most commonly occur in infancy and childhood.Since surgical therapy is the primary treatment modality for any type of teratoma, we Gas and Fuel and Oil and Solution Filters as anesthesiologists encounter these cases when they come for surgical removal.Providing anesthesia services for these cases is challenging
ABSTRACT: An electromagnetic parametrically excited rolling pendulum energy harvester with self-tuning mechanisms subject to multi-frequency excitation is proposed and investigated in this paper.The system consists of two uncoupled rolling pendulum.The resonance frequency of each the rolling pendulum can be automatically tuned by adjusting its geom
