Abstract Honeycomb cored sandwich structures have been attracted extensive attentions attributed to outstanding explosion and impact protection capability. Herein, in order to improve the anti-blast performance of re-entrant honeycombs (RH) cored sandwich panel, the conventional RH is reinforced by introducing catenary in the form of connecting both ends of horizontal cell walls and catenary. The results show that the deformation mode of the reinforced RHs (RRH) becomes more stable and regular compared to RHs, and the energy absorption of classic RHs can be enhanced because the reinforced structures and the improved auxetic deformation are employed simultaneously.… More >

Abstract Rice blast disease is one of the most devastating diseases of rice (Oryza sativa L.) caused by the fungus Magnaporthe oryzae (M. oryzae), and neck blast is the most destructive phase of this illness. The underlying molecular mechanisms of rice blast resistance are not well known. Thus, we collected 150 rice varieties from different ecotypes in China and assessed the rice blast resistances under the natural conditions that favoured disease development in Jining, Shandong Province, China in 2017. Results showed that 92 (61.3%) and 58 (38.7%) rice varieties were resistant and susceptible to M. oryzae, respectively. Among the 150… More >
