in this paper, the exp-function method, with the aid of a symbolic computation system such as maple, is applied to the (2+1) -dimensional calogero bogoyavlanskii schiff equation. exact and explicit generalized solitary solutions are obtained in more general forms. the free parameters can be determined by initial or boundary conditions. the method is straightforward and concise, and its applicat...

Relations between children's imaginary companion status and their engagement in private speech during free play were investigated in a socially diverse sample of 5-year-olds (N=148). Controlling for socioeconomic status, receptive verbal ability, total number of utterances, and duration of observation, there was a main effect of imaginary companion status on type of private speech. Children who...

Abstract In recent years, several studies have attempted to trace the evolution of fashion system in a globalised context and pluralized societies. This paper follows footsteps similar research, focusing particular on Afro-Italian fashion, i.e. garments created by designers African descent who chosen Made Italy - its rules, structures conventions as tangible symbolic place give form their creat...

The corrosion inhibition effect of N,N′-bis(n-Hydroxybenzaldehyde)-1,3-Propandiimine on mild steel has been investigated in 1 M HCl using electrochemical impedance spectroscopy. A predictive model was presented for Nyquist plots using an artificial neural network. The proposed model predicted the imaginary impedance based on the real part of the impedance as a function of time. The model to...
