Hazard Identification and Risk Assessment (HIRA) in Compressed Natural Gas (CNG) stations
It is possible by the categorization of the estimated levels of Individual Risk (IR) which the proposed site would impose upon them. An analysis of the consequences and likelihood of credible accident scenarios coupled with acceptable risk criteria is then undertaken. According to the results in many cases, not only required distances have not been provided but also CNG stations are commonly located in vicinity of populated areas to facilitate refuelling operations. Natural gas is in priority because of the relative abundance, ease of use, less environmental pollution, and the price is cheaper than gasoline. This study was done to identify and determine the operational deviations in one of the CNG gas compressors and proposed hazard control measures. Identification of possible causes of deviations in compressor performance and risk assessment was done in several meeting with cast HAZOP experienced experts. Seven operational deviations identified in the performance of the compressor used in CNG station includes no & less flow, more & less pressure, presence of compounds other than gas in compressor, reverse flow and more temperature. 41.34% of the risks were in acceptable range, and 58.66% was in conditionally acceptable. Prepare work instructions, worker education, fix and maintenance and regularly equipment calibration can be useful in prevention of accidents in CNG stations.

Design and analysis of robot for Industrial Application
Basically, robots are designed in such way that they remove human intervention from labour intensive and hazardous work environment, sometimes they are also used to explore inaccessible work places which are generally impossible to access by humans. The coating of internal pipes comes in same category because they carry toxic chemicals, fluids and most of the time has small internal diameter or bends which become inaccessible to human. The complex internal geometry and hazard content constraints of pipes demand robots for coating of such pipes to prevent corrosion level of pipe, recovery of usable parts from pipe interior, sampling of sludge and scale formation on pipe internal surface etc. Several designs of In-pipe coating robots (IPCR) have been proposed in the literature to solve the problems related with of these complicated coating of internal geometries. Designing of an in pipe coating robot (IPCR) is a difficult task and hence the designer must take care of the design issues like Mobility, Steer ability,, Size and shape adaptability, Online adaptability, Flexibility, Stability, Autonomous operation and obstacle avoidance, Efficiency at uneven surface, Safe operation, Material selection, Type of task to be performed inside the pipe, Number of actuators, Operation in active pipe line, Retrieval of robot, User friendly navigation and control system, Range of operation, Quantitative analysis of defects inside the pipe. Based on above, research work presents investigations into design issues pertaining to development of In-pipe coating robotics and proposes a new model of an In-pipe coating robot to overcome some critical design issues. This proposed model is a screw driver type wall press adaptable wheeled In-pipe coating robot. It can move through vertical, horizontal pipes and it can easily pass through elbow of a pipe.

Smart medical package
The prime objective of this project is to create a smart package for medicines using the printed electronics technique which enables LED light to glow. Insulin’s that are used in houses might not be stored under proper storing temperature. So a temperature sensing circuit is printed in the insulin package with a LED light glowing for indicating the improper storing temperature. When the user handles this package, it provides information about the storage temperature of the medicine. Screen printing technology is employed for circuit printing and digital printing for package printing. Silver conductive ink is used for circuit printing and components pasting. SMD (Surface Mount Device) components are used in the circuit. A smart package is developed to deliver the information exactly, thus making packages smarter will enable the users to grab the information easily and can be used in an effective way.

Synthesis of nanostructured silver particles incorporated vein graphite for the anode material application in rechargeable lithium-ion batteries
Rechargeable lithium-ion batteries have emerged as the dominant energy storage source due to their higher capacity, energy density and excellent cyclability. Graphitic materials are commonly utilized as the anode material for lithium-ion batteries. Silver nanoparticles incorporated vein graphite (SVG) materials were prepared for Li Ion Battery (LIB) applications. The graphite sample was purified by acid leaching, followed by modifying the surface with HNO3. The silver graphite composite material was synthesized using AgNO3 as the precursor and trisodium citrate as the reducing agent. Phase analysis revealed that the silver nanoparticles have been successfully incorporated into the surface of the modified graphite after chemical reduction and mechanical agitation. Half-cell testing was carried out using CR 2032 coin cells with silver vein graphite composite as the active material and 1 M LiPF6 (EC: DMC; vol. 1:1) as the electrolyte at the National Center for Advanced Battery Research in NIFS. Galvanostatic charge-discharge study of the cell with silver vein graphite composite showed an initial charge-discharge Coulombic efficiency of 88.3% and a promising discharge capacity of 373 mAh g-1 in the voltage range of 0.002 - 1.5V at C/10 rate. Overall, the electrochemical performance of our developed nanostructured silver particles incorporated vein graphite anode shows a noticeable improvement of the reversible capacity, Coulombic efficiency and cycling behaviour.

Breaking the Barriers: Making Unicorns Common
In this constantly changing time, it is very important what all factors can lead to more disruptive innovation and the establishment of new ventures. It is necessary to research what is stopping individuals to enter into entrepreneurship. Due to high unemployment rates around the world, there is an immediate requirement to increase the labour force participation rate. Entrepreneurship is one big solution that can not only increase employment in current times but will also increase GDP in the long run. This will also present us with the opportunity to innovate in this constantly changing environment. This research paper discusses the misconceptions that act as barriers to entry in the start-up ecosystem and the role of government in breaking these barriers.

Impact of a Pandemic on Indian Economy
In the following paper, we investigate the impact of a pandemic on the Indian Economy. The main focus of this study is to find out the economic impact in all the various sectors, which will help us in understanding the pandemic better, and how deep is the impact. This study considers various reports and concludes that despite the sluggish economic growth of India since 2019, the outbreak of COVID-19 has led to a further drop in the Economy. The nation has also been listed as among the top affected nations across the globe due to the pandemic. As a nation we’ve faced a lot of economic challenges due to pandemic breakout. It has majorly adverse sectors like food security, informal sector, agriculture, also aviation industry, shortage of labor for harvesting, PDS, and social security. This is a resultant of no proper infrastructural capacity to suffice a pandemic. Given our population, we have no resources to source functionality in the nation. Also, the health sector has also suffered a lot from the poor health facility, too costly checkups. The social life of the Indian people affected by the coronavirus includes the hike in Domestic Violence, Communalism, Fake news, and Religion.
