abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
In this paper we develop the monotone method in the presence of lower and upper solutions for the problem u(t) = f(t, u(t));u(a) − u(b) = λi ∈ R; i = 0, ..., n− 1. Where f is a Carathéodory function. We obtain sufficient conditions in f to guarantee the existence and approximation of solutions between a lower solution α and an upper solution β for n ≥ 3 either α ≤ β or α ≥ β. For this, we study...
The method of lower and upper solutions for the cantilever beam equations with fully nonlinear terms
In this paper an efficient Algorithm based on Zadeh's extension principle has been investigated to approximate fuzzy solution of two-point fuzzy boundary value problems, with fuzzy boundary values. We use finite difference method in term of the upper bound and lower bound of $r$- level of fuzzy boundary values. The proposed approach gives a linear system with crisp tridiagonal coefficients matr...
