Quenching characteristics based on the two-dimensional (2D) nonlinear unsteady convection-reaction-diffusion equation are creatively researched.The study develops a 2D compact finite difference scheme Electrical Tape constructed by using the first and the second central difference operator to approximate the first-order and the second-order spatial
With the development of spacecraft, the brittle materials like ceramics and glass have been used for significant components especially in optical and thermal systems.However, they are vulnerable to damage by hypervelocity impact of space debris and micrometeoroids.Against a backdrop of increasing number of space debris, impact-damage evaluation on
Abstract Background Human cytomegalovirus (HCMV) infection of the central nervous system (CNS) is a rare but life threatening condition which may follow hematopoietic stem cell transplantation.Diagnosis, monitoring and treatment approaches rely on anecdotal reports.Case presentations The different outcomes of HCMV CNS disease in an adult and a pedi
he modulation of guard cell function is the basis of stomatal closure, essential for optimizing water use and CO2 uptake by leaves.Nitric oxide (NO) in guard cells plays a very important role as a secondary messenger during stomatal closure induced by effectors, including hormones.For example, exposure to abscisic acid (ABA) triggers a marked incre
