The monograph describes the mixing ratios of ambient NH3 and other trace gases (NO, NO2, CO, SO2, and HNO3) and its interaction over urban and suburban areas, the Himalayan region and oceanic region of India. The average mixing ratios of ambient NH3, NO, NO2, SO2 and CO were recorded as 19.3 ± 4.4 ppb, 21.1 ± 5.8 ppb, 18.6 ± 4.6 ppb, 1.7 ± 0.5 ppb and 1.8 ± 0.8 ppm, respectively in megacity Delhi. The average mixing ratios of ambient NH3, NO, NO2 and SO2 have recorded as 7.0 ± 2.6 ppb, 3.1 ± 1.2 ppb, 3.9 ± 1.4 ppb and 1.7 ± 0.7 ppb, respectively over the Himalayan region of India. The comparatively low value of these trace gases was recorded over the Bay of Bengal. The results emphasized that the traffic could be one of the dominant sources of ambient NH3 at the urban sites of India. NH3 emission from rice-wheat cropping system of subtropical agricultural soil of Delhi, India has also been demonstrated. About 9% of the applied fertilizer N was lost as NH3 during the rice-wheat cropping system. Relationship of NH3, NOx, SO2, and HNO3 and ionic species of PM2.5 indicate the dominant role of ambient NH3 in the formation of secondary inorganic aerosols over the urban sites of India.

Blockchain Technology Solutions for the Security of IoT-Based Healthcare Systems explores the various benefits and challenges associated with the integration of blockchain with IoT healthcare systems, focusing on designing cognitive-embedded data technologies to aid better decision-making, processing and analysis of large amounts of data collected through IoT. This book series targets the adaptation of decision-making approaches under cognitive computing paradigms to demonstrate how the proposed procedures, as well as big data and Internet of Things (IoT) problems can be handled in practice. Current Internet of Things (IoT) based healthcare systems are incapable of sharing data between platforms in an efficient manner and holding them securely at the logical and physical level. To this end, blockchain technology guarantees a fully autonomous and secure ecosystem by exploiting the combined advantages of smart contracts and global consensus. However, incorporating blockchain technology in IoT healthcare systems is not easy. Centralized networks in their current capacity will be incapable to meet the data storage demands of the incoming surge of IoT based healthcare wearables.
