The present research, utilised only renewable oil samples to reduce atmospheric pollution and also to decrease our reliance on fossil oil products and provide a direction towards alternative fuel usage in diesel engines. On a 1-cylinder, naturally water-cooled, 4S, CI diesel engine, the tests have been conducted as to create comparative results of performance-emission characteristics in between the blends of conventional diesel, biodiesel thumba, biodiesel polanga and ethanol fuel. With blends, the diesel engine has been tested as such: diesel fuel (D100) (v/v), thumba biodiesel 100% (T100) (v/v), polanga biodiesel 30% with addition of diesel 70% (P30) (v/v), and ethanol 10% with addition of diesel 90% (E10) (v/v). The engin performance parameters: BTE of E10 and P30 blend was incremented than the diesel fuel, while the blends T100 was close enough to diesel fuel as well; whereas, BSFC data of E10 blend was the lowest in between the others samples and for T100 and P30 also it decreased. The emission values for CO, NOx and UHC of the blend samples was less than diesel fuel. The maximum CO2 emission was released by D100 and least by P30 fuel blend, whereas, the unused O2 released was the reverse. The effects of direct inhalation of biofuel blends in IC engine were analysed properly and in near future this alternative oil can be applied in our society.
The aim of the study is to evaluate the post COVID-19 transition in dentist providing dental health care to children. Materials and Methods : A cross-sectional questionnaire based survey was conducted among the dentists to assess the transition post COVID-19 towards dental health care to children. The survey was carried out with a sample of 110 respondents. Results: The results shows that the COVID-19 outbreak had definitely made the dentists uncomfortable in treating the patients and majority (55.4%) of them agree that even children can be asymptomatic carriers. Moreover, 83.7% of the dentists agreed that the PPE kit will definitely increase the fear and anxiety among the children, 75.5% dentists agreed that this will also lead to increase in the cost of the treatment. Even before the COVID-19 pandemic majority of the dentists never used the N2O for managing the pediatric patients and even after such scenario they are not planning to use N2O for pediatric behavior management. Conclusion: Dental professionals must be fully aware of 2019-nCoV spreading modalities, how to identify patients with this infection, and, most importantly, self-protection considerations. The aerosols and splatter generated during dental procedures have the potential to spread infection to dental personnel and other people in the dental office. Dentists can play a significant role in disrupting the transmission chain, thereby reducing the incidence of disease by simply postponing all non-emergency dental care for all patients.
The present work was conducted on a 1 DI CI engine, on which neat diesel, neem biodiesel and polanga biodiesel and ethanol fuel were tested by varying the load on the engine setup at various blend ratios such as: -diesel fuel 100% (D100), biodiesel neem 100% (N100), biodiesel polanga 50% blended with diesel 50% (P50), and ethanol 5% blended with diesel 95% (E5).The research carried was to compar the performance-emission characteristics of various blend samples w.r.t neat diesel fuel. The performance results show that, the BTE of N100, P50 fuel blends was less than E5 blend, as compared to neat diesel, whereas, the BSFC of D100, E5 blend had a decreasing nature than N100 and P50 blend. The CO emissions among the biofuel blends was maximum for N100 and then P50 blend but the least was for E5 blend w.r.t neat diesel. Also, the UHC emission for N100, P50 and E5 blends had a decreasing trend than neat diesel fuel. The D100 fuel had a maximum NOx emission in comparison to others and the least was by E5 blend. The CO2 emission of N100 and D100 was the highest than P50 and E5 blends during the operation. The unused O2for N100 fuel was the least than other fuel samples and the maximum was for E5 blend. The biofuel blends being used here had an effective outcome which can be utilised as an substitute for neat diesel.
