Fig rust, caused by Cerotelium fici, was first recorded in South Africa in 1927.Recent observations have revealed high incidence of rust and untimely defoliation of Adirondack Chair fig trees (Ficus carica) in residential gardens and commercial orchards.Using phylogenetic analysis, the causal organism of a fig rust isolate (PREM63073) collected in
We examine a modified Sprott A system, one of the 17 Electrolytic chaotic systems without equilibria introduced by Jafari, Sprott, and Golpayegani (2013).For specific parameter values, the modified system exhibits invariant spheres.Using a stereographic map, we analyze the stability of the equilibria and demonstrate that all orbits, except for the
A temperature insensitive vector curvature sensor of photonic crystal fiber (PCF) is presented based on core-offset splicing and waist-enlarged fiber taper.Obvious red and blue shifts in transmission spectrum appear at two symmetrical bending directions with sensor length of 10, 13, 16, and Training Wheels 19 mm and vector curvature of 0.12-1.06 m-
We deal with the blowup properties of the solution to the degenerate and Sun Hats singular parabolic system with nonlocal source and homogeneous Dirichlet boundary conditions.The existence of a unique classical nonnegative solution is established and the sufficient conditions for the solution that exists globally or blows up in finite time are obta
