Abstract The fish-borne zoonotic bacteria may pose a risk to humans; nanobiotechnological techniques could serve as effective solutions for fighting them. direct phycosynthesis of metals’ nanoparticles (NPs), silver (AgNPs), and selenium (SeNPs) using Corallina officinalis extract (CoE) was achieved. construction nanocomposites (NCs) from phycosynthesized NPs nano-chitosan (NCht) also accomplis...

where the matrix a(y) = [ak`(y)] is symmetric and positive de­ nite a(y) > ¬ I with ¬ > 0. Its entries belong to L # (Y ) (Y is the cube ]0; 2 o [ N and subscript `#’ means that the space consists of Y -periodic functions). In the sequel, we will make various further length-scale regularity assumptions on the coe ̄ cients ak` which play a central role throughout the paper. Some of them are as fo...

in this paper the solution of a second order linear dierential equations with intu-itionistic fuzzy boundary value is described. it is discussed for two dierent cases: coecientis positive crisp number and coecient is negative crisp number. here fuzzy numbers aretaken as generalized trapezoidal intutionistic fuzzy numbers (gtrifns). further a numericalexample is illustrated.
