in the present study, sulfuric acid was used for artemia cysts decapsulation. cysts of artemia franciscana were hatched out in regular manner or following hypochlorite or acid decapsulation. two acid concentrations (1 and 5%), three acid immersion times (10, 30 and 50 min) were used and hatching rates were recorded after 15, 18 and 24 h incubation. hatching rates increased but hatching time dec...

some preliminaries about the integrable families of riccati equations and solutions structure of these equations in several cases are presented in this paper, then by using of definitions for fractional derivative we apply the new extended of tanh method to the perturbed nonlinear fractional schrodinger equation with the kerr law nonlinearity. finally by using of this method and solutions of ri...

We make two significant contributions. First, we introduce a new technique for solution based learning in Quantified Boolean Formulae (QBF’s.) This takes advantage of the structure of QBF’s to improve on previous methods. More information is extracted from each solution learnt, so fewer states need to be visited later in search. Unfortunately, our empirical results suggest that our learning tec...

Android is among the new breed of smartphone software stacks. It is powerful yet friendly enough to be widely adopted by both the end users and the developer community. This adoption has led to the creation of a large number of thirdparty applications that run on top of the software stack accessing device resources and data. Users installing third party applications are provided information abo...

In this work we consider viscosity solutions to second order partial differential equations on Riemannian manifolds. We prove maximum principles for solutions to Dirichlet problem on a compact Riemannian manifold with boundary. Using a different method, we generalize maximum principles of Omori and Yau to a viscosity version.
