Phenomenological evidence suggests the existence of non-trivial background fields in the QCD vacuum. On the other hand SU(3) gauge theory possessses three different classes of both non-generic and non-trivial strata that may be used as classical backgrounds. It is suggested that this threefold multiplicity of non-trivial vacua may be related to the existence of particle generations, which would...

Today wireless services are the most preferred services of the world. The rapid increase in the service is due to the advancement of technology consecutively. The worldwide revolution in mobile and internet technology have changed our way of living life. Every new technology has come to hide the drawbacks of previous technology. In this paper we throw a light on the various generations of mobil...

There have been several experiments 10,11,12,13 which suggest neutrino oscillations. To explain the solar, atmospheric and LSND data within the framework of neutrino oscillations, it is necessary to have at least four kinds of neutrinos. It has been shown in the two flavor framework that the solar neutrino deficit can be explained by neutrino oscillation with the sets of parameters (∆m⊙, sin 2 ...

OBJECTIVE To assess the intergenerational repetition of breastfeeding duration in a cohort of adolescent mothers who had been prospectively followed up since birth. METHODS All hospital births occurred in Pelotas (N=5,914), a Southern Brazilian city, in 1982 were studied prospectively. The cohort was visited in 1984 and 1986, and information on feeding practices was gathered. In 2001, a searc...

The paper describes present condition in education system in regard to current social circumstances, both national and foreign ones. Also, the issue of unpreparedness (at all possible levels) regarding the impact of foreign “interested parties” is treated. Specific interest exists for the possible innovation of university teaching and the active engagement of both academics and students. Resear...

A father and son, both affected by a skeletal dysplasia with severe craniofacial deformities, are reported and compared to three previously described isolated cases of the same dwarfism. The principal features are craniosynostosis, multiple lucent metaphyseal defects, flattening and anterior beaking of the vertebral bodies, and abnormal dentition. Autosomal dominant inheritance is suggested.

This chapter asks whether equal treatment of generations is compatible with social discounting. It presents the rank-discounted utilitarian criterion, proposed by Stéphane Zuber and analyzed in Zuber and Asheim (2010), which combines equal treatment with social discounting by giving priority for the worse off not only due to their absolute level of well-being but also their relative rank in wel...

Introduction: Nowadays there is an important distance between generations in our society, especially between senior citizens and young people, who do not regularly live together. In addition, it has been demonstrated that the transfer of knowledge and experience, are the keys to sustainability of culture and tradition, as well as the transfer of values. In this context, it is necessary to promo...
