Abstract Chitosan is one of the most abundant carbohydrate biopolymers in world and chitosan oligosaccharide (COS), which prepared from chitosan, a plant immunity regulator. The present study aimed to validate effect COS on inducing resistance tobacco mosaic virus (TMV) Arabidopsis investigate potential defence-related signalling pathways involved. Optimal conditions for induction TMV were pretreatment at 50 mg/L 1 day prior inoculation with TMV. Multilevel indices, including phenotype data...
Ring shear tests were performed in this work to investigate the characteristics of band formation and particle breakage for calcareous sands sampled from South China Sea. The focused on evolution under various levels loading stress, together with sensitivity analyses initial sample grading rate. particles has a significant influence stress-strain relationship, volumetric deformation, final sands. In particular, sand specimen tends remain at constant volume stable strains larger than 2,000%....
It is commonly accepted that the macroresponse of soil depends significantly on microscopic particle characteristic features, such as size, shape, and roughness. These parameters can be obtained readily by dynamic image analysis each individual particle, enabling quantification morphologies. This study investigated variation calcareous sand morphology before after one-dimensional normal compression. The tests employed a large oedometer cell (231.6-mm inner diameter 155-mm height) coarse...
The consolidated drained triaxial shear tests have been performed in this work to investigate the shearing behavior of calcareous sands sampled from South China Sea, with focus on analyzing influence particle breakage materials strength. At approaching failure limit state, intense and rearrangements prevented stress increasing further. Depending initial packing density, loose sand sample exhibited strain-hardening response, while dense strain-softening response clear dilatancy after peak...
Catastrophic failure in engineering structures of island reefs would occur when the tertiary creep initiates coral reef limestone with a transition from short- to long-term load. Due complexity biological structures, underlying micro-behaviors involving time-dependent deformation are poorly understood. For this, an abnormal phenomenon was observed where axial and lateral deformations were mutually independent by series triaxial tests under constant stress strain rate conditions. The...
Coral reef limestone (CRL) is a marine sedimentary rock dominated by biogenesis, and its composition as well internal structure characteristics are different from traditional terrigenous rocks. This article used CT scanning petrographic thin section observations to visually quantitatively analyze crack morphological after triaxial shear failure at microscopic scale. The analysis revealed the mechanism of initiation propagation perspectives geological genesis fracture mechanics. Results show...
Although soil–rock mixtures (S-RMs) exist extensively on Earth's surface, their mechanical behaviors remain elusive. In this study, a series of large-scale direct-shear tests was conducted to investigate the S-RMs composed weathered basalt with different rock block contents, including stress–strain relationship, dilatancy, particle breakage, and shear strength. The results indicate that S-RM shows more pronounced strain-hardening behavior as its content increases. For there is power law...
Abstract Strains from Trichoderma reesei have been used for cellulase production with a long history. It has well known that biosynthesis by the fungal species is controlled through regulators, and elucidation of their regulation network great importance engineering T. robust production. However, progress in this regard still very limited. In study, RUT‐C30 was transformed an artificial zinc finger protein (AZFP) library, mutant M2 improved screened. Compared to its parent strain, filter...
