Abstract Comparative biological morphology, incorporating the study of active reaction, is contrasted with genetics as passive mutation. Geneticists investigate anatomical characters, never constructions, which are capable reorganization when biological-morphological equilibrium organism has been disturbed. The anatomy Opisthocomus cristatus and Stringops habroptilus demonstrate that three succ...

Abstract: Potato virus Y a type species of the genus potyvirus infects several crops in the family solanaceae. PVY isolated from field infected peppers was identified on the basis of host reaction, serological and molecular characterization. The result of ELISA, Immunoblot electrophoresis and Immuno Capture Reverse Transcription Polymerase Chain Reaction   (IC-RT-PCR) indicated that...

We introduce a model of three-species two-particle diffusion-limited reactions A + B → A or B, B + C → B or C, and C + A → C or A, with three persistence parameters (survival probabilities in reaction) of the hopping particle. We consider isotropic and anisotropic diffusion (hopping with a drift) in 1d. We find that the particle density decays as a power-law for certain choices of the persisten...
