common pistachio psylla, agonoscena pistaciae burckardt and lauterer (hemiptera: aphalaridae) is one of the economical pest among the pistachio orchards. the adonis' ladybird, hippodamia variegata (goeze) (col: coccinellidae) is one of the most prominent coccinellid predator in pistachio orchards. it is omnivorous and feed on aphids and psylla. functional response studies using a suitable ...

This paper describes a method for analysing the timing properties of exception handling in Ada. The paper first describes how exceptions are implemented and considers the use of exceptions in the SPARK, Safe/Ada and ANNA subsets. A static analysis technique for reasoning about exception propagation is then presented. We argue that this technique, along with a suitable subset and detailed knowle...

The authors present a higher-order Godunov method for the solution of the twoand three-dimensional equations of ideal magnetohydrodynamics (MHD). This work is based both on a suitable operator-split approximation to the full multidimensional equations, and on a one-dimensional Riemann solver. TIlls Riemann solver is sufficiently robust to handle the nonstrictly hyperbolic nature of the MHD equa...
