In the Ha'il region, in the north of Saudi Arabia, an investigation of 13 study sites shows that the Acacia population is mainly composed of three species: A. gerrardii (90.3%), A. ehren...

In this study, the two-phase (particle-fluid) Newtonian fluid is studied when flowing through a sieve tube. The model of phloem is assumed with permeable walls. The flow is important for the study of the transport of food in plants. Leaves prepare food using sunlight and minerals transported from roots to leaves using xylem cells which operate pred...
