Automating Acquisition through SOUL 3.0
Abstract: Library automation is an integral part of the development process of any library or resource center. Traditionally this includes automation of acquisition, serialization, cataloging and circulation. But most libraries do list entries of reading material and display them via OPAC. These libraries have been equally successful in computerized issues and returns. But the real difficulty lies in the automation of acquisition activities. It is forgotten that cataloging begins with acquisition. …

SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA
Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …
