Most of the street-based children are not educated beyond primary school and their living conditions are based on begging and doing odd jobs in the market and streets. Forty-six percent of the on-the-street children live with one parent, and 97 percent of the of-the-street children have lost contact with their parents. The on-the-street children have a higher percentage of family sector networks than the of-the-street children and the shelter or institutionalized children. Generally, school children still have strong family ties.
The correlation amplitude for the quasi-particles in high T{sub c} superconductors has been deduced. From this amplitude, the maximum critical transition temperature has been calculated. The assumption, which has been made is that, the superconductivity is due to condensation of electron pairs, which may be in a parallel spin-state, an antiparallel spin-state, or a mixture of the two states. It has been established that the maximum transition temperature in the optical phonon frequency is T{sub c} = 262.6 K irrespective of the state of the electron pair. (author)
