Satellite Communications Satellite communications are the outgrowth of development in two main areas, space technology and communication technology. The first requirement for any space activity has, however, nothing to do with the state of technology since it concerns the ability to compute the velocity needed to escape earth’s gravity and, as a next step, to a satellite in orbit. This knowledge comes out of a very old branch of science,...

  Conservation of Forests Essay No. 01 Floods, population problems and other environmental hazards have been increasing. The environmental hazards in this country have not reached the stage prevailing in several highly industrialized countries. We are, however heading to it. Lack of adequate vegetate cover in the catchments or watersheds of our rivers and streams, exploitation of our hill forests indiscriminately to meet the ever-increasing needs of population, the indiscriminate lopping,...

  Forests for National Welfare  Few sights are more beautiful than trees whether in flower or with their branches laden with fruit or just the countless variety in shape and colour of leaf and of the tree itself.
