This paper provides a simple techno-economic study of various access network technologies for broadband data service delivery, including their deployment cost analysis. This study compares the deployment cost per unit bandwidth of different access technologies from a city perspective and can serve as a guideline for future access network deployment in the urban area.

No difference was observed in thein vitro growing ability of granule cells isolated from hypothyroid or normal rat brain. When granule cells were taken from hypothyroid rat brain and grown in normal culture medium containing 10% fetal calf serum, they behaved similarly to the granule cells obtained from normal rat brain. In both cases there were progressive losses ofin vitro growing ability of the granule cells with the age of the animal and it became impossible to grow them when derived from 21 days or older animals. A marked decrease in cell surface GM1 was observed when the cells were maintained under thyroid hormone-deficient conditions in culture. Anti-GM1 antibody was found to inhibit significantly the migration of granule cells along the astrocyte fibers. These results indicate that GM1 has an important role in thyroid hormone-dependent postnatal brain maturation in rat.
