Book Synopsis India-Iran Relations by : Sujata Ashwarya
Download or read book India-Iran Relations written by Sujata Ashwarya and published by Routledge. This book was released on 2017-04-21 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines India’s relationship with Iran since the post-World War II period and its unique search for meaningful bilateral ties in the West Asian region in the context of the changing regional and international scenarios. The four chapters highlight the achievements and constraints on the development of Indo-Iranian relations during the Cold War era; opportunities and limitations in bilateral engagements between India and Iran in the aftermath of the Cold War; impact of the ‘US factor’ on the development of crucial Indo-Iranian energy ties and the limitation imposed by India’s relations with Israel and Saudi Arabia on the India–Iran ties. More specifically, the four chapters touch on the central drivers—energy imports, access to Central Asia, cooperation in Afghanistan, mutual trade and economic investments and security ties—of India’s Iran policy, and how they structure India’s interaction with the other countries of the region and impact on the articulation of national interests. Combining a rich interplay of facts and figures with nuanced analyses, this volume will be a valuable resource for scholars, policymakers, diplomats and any interested reader desirous of knowing more about Indo-Iranian relations in particular and India’s West Asia policy in general.

Download or read book Biohybrid Systems written by Ranu Jung and published by John Wiley & Sons. This book was released on 2011-11-30 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discipline of neurodesign is a highly interdisciplinary one, while at the same time in the process of maturing towards real-life applications. The breakthrough about to be achieved is to close the loop in communication between neural systems and electronic and mechatronic systems and actually let the nervous system adapt to the feedback from the man-made systems. To master this loop, scientists need a sound understanding of neurology, from the cellular to the systems scale, of man-made systems and how to connect the two. These scientists comprise medical scientists, neurologists and physiologists, engineers, as well as biophysicists. And they need the topics in a coherently written work with chapters building upon another.
