Semiconducting metal oxide-based gas sensors have inadequate selectivity as they are responsive toward a variety of gases. Here, we report the implementation of gas sensing kinetic analysis of the sensor to identify the tested volatile organic compounds (VOCs) (2-propanol, formaldehyde, methanol, and toluene) precisely. A single chemiresistive sensor was employed having tin oxide-based hollow spheres as the sensing material, which were obtained by chemical synthesis. The gas sensing measurements were conducted in a dynamic manner where the sensor displayed excellent response with high sensitivity. Eley–Rideal model was adopted to obtain the kinetic properties of the gas sensing phenomenon through theoretical fitting of response transient curves and their corresponding kinetic parameters. The calculated characteristic kinetic properties were further examined to discriminate among different VOCs. The approach of using gas sensing kinetic analysis for multiple gas discrimination is an attractive solution to mitigate the problem of cross-sensitivity for resistive gas sensors.

The focus of Indian agriculture so far has been on meeting the national demand, however it is going through a steady transformation phase to address the global requirement and is being driven by consumers and markets. According to APEDA Agriexchange portal, every year our country suffers more than 17000 Cr losses because consignments get rejected [I]. There is a growing concern for the food quality and scrutiny of the food supply chain [2] due to increased use of pesticides and its impact on health [3].As a result, awareness of the importance of safe food is rapidly increasing among the consumers worldwide. Global standards like Global GAP (Good Agriculture Practices) [4], Better Cotton Initiative, Table Responsible Soy) etc. have evolved with the collaborative efforts of growers, industry experts, researchers and retailers around the globe. These certifications contain standardized processes for producing fresh food resulting in good quality and environment sustainability. These mostly involve audit and documentation processes, in English, with Site Inspectors and Auditors visiting the field and recording their observations on paper. Hence the scalability is a challenge and the adoption is low. ICT can play an important role in bringing traceability, simplification and ensuring adaptation of the standard farming practices in India. IT tool has the capability of determining the physical location of the source of the product and also the sequence of events for traceability. The objective of this paper is to bring about a solution for Agriculture Process Standards Implementation that benefits holistically -quality, quantity of the produce and health and environmental needs. This paper brings about field experiences in implementation of GAP Certification in Amravati district (Maharashtra) for Orange Producer Group using mKRISHI-GAP system. RTRS (Round

Information and Communication Technology (ICT) has made a significant impact on the functioning of enterprises and the urban communities. However benefits of ICT revolution are yet to reach the rural communities. In this paper, we show how communities in rural area can benefit from informatics, for their primary healthcare needs. We describe an innovative community informatic tool called 'mHEALTH-Primary Health Care' (mHEALTH-PHC), to meet the primary healthcare requirements of the community, developed after studying the needs and the logistic problems related to primary healthcare of the rural tribal population in villages. The paper also covers the adoption challenges and how they are dealt with. mHEALTH-PHC solution is designed, considering the existing infrastructure of public health system in the rural area. The field experience shows that healthcare personnel involved at various levels in Primary Health Center (PHC) are comfortable in using the tool and are enthusiastic to employ such a tool for efficient service to the community. Satisfaction of both, the health personnel and the end beneficiaries is the first level of success for making a mark. mHEALTH-PHC has crossed the first level barrier.
