Abstract
In many parts of the world, shipping-related emissions have already exceeded or are expected to soon exceed those from land-based sources. Shipping emissions can be reduced substantially by using some of the same technologies being applied to land-based sources, including cleaner engines and fuels, exhaust control methods, and operational modifications. Various ports are testing the feasibility of these mechanisms with varying degrees of success. What is perhaps most greated needed is expedited creation of better regulations at all levels, from the Interational Maritime Organization to port city authorities.

Abstract

Online learning is a new form of distance learning or distance education. Technological inputs are constantly improving distance education. Various forms of distance education like correspondence, radio and television have existed for many decades now. But they all faced one major hurdle - lack of interaction between instructors and students because of the inherent nature of media. The advent of internet has solved this problem to a great extent. Interactivity is the hallmark of online medium. It is possible to communicate for students with instructors and also with fellow students as well as resource persons, through the use of web technologies. For the first time in distance learning, the student is no more a passive receiver of educational material. Learners have a real chance to use different tools to maker their learning experience as close to a face-to-face situation.

Abstract

India’s post-independence policy of using science and technology for national development, and investment in research and development infrastructure resulted in success in space, atomic energy, missile development and supercomputing. Use of space technology has impacted directly or indirectly the vast majority of India’s billion plus population. Developments in a number of emerging technologies in recent years hold the promise of impacting the future of ordinary Indians in significant ways, if a proper policy and enabling environment are provided. New telecom technologies -- a digital rural exchange and a wireless access system -- are beginning to touch the lives of common people. Development of a low-cost handheld computing device, use of hybrid telemedicine systems to extend modern healthcare to the unreached, and other innovative uses of IT at the grassroots also hold promise for the future. Biotechnology too has the potential to deliver cost-effective vaccines and drugs, but the future of GM crops is uncertain due to growing opposition. Some of these emerging technologies hold promise for future, provided a positive policy and enabling environment.
