This paper presents a focused comparative case study considering the korpskaft influence of natural and synthetic fibers on the fresh and mechanical properties of concrete.Locally sourced 19 mm long sisal fibers from sisalana leaves and manufactured polypropylene fibers were incorporated in a normal strength concrete matrix with fiber volumetric co
The oriented nanotubes reinforced styrene butadiene rubber (CNTs/SBR) composites were prepared by applying the mechanical shear induction method, and the laws of carbon tube content and orientation on the mechanical and tribological properties of the composite rubber materials were investigated.The mechanisms of these results were analyzed.The resu

Abstract In this paper, we consider the effects of the small and abrupt random perturbations in the environment, and formulate a stochastic single species model with Allee effect and jump-diffusion.We first prove that craggy range sauvignon blanc 2022 the model admits a unique solution which is global and positive.Then we study the stochastic perma
