Effect of hydrogen addition on combustion and emissions performance of a high speed spark ignited engine at idle condition

The fuel depletion and environmental pollution have pushed studies on improving the combustion and emission characteristics of internal combustion engines with several alternative fuels. Expert studies proved that hydrogen is one of the prominent energy source which has exceptional combustion qualities that can be used for improving combustion and emissions performance of gasoline-fueled spark ignition engines. This paper introduced an experiment conducted on a single cylinder high speed gasoline engine equipped with a hydrogen injection system to discover the combustion and emissions characteristics with various hydrogen gasoline blends at idle condition. For this purpose, the conventional carburetted high speed spark ignition engine was modified into an electronically controllable engine with help of electronic control unit which dedicatedly used to control the ignition timings and injection duration of gasoline fuel

IMPACT OF COVID-19 PANDEMIC ON QUALITY OF LIFE AMONG COVID-19 SURVIVORS IN SELECTED AREAS OF SOUTH INDIA

<p><strong>Background: </strong>Corona virus Disease 2019 (COVID-19) was first detected in December2019 in Wuhan, Chinaand World Health Organization declared COVID-19 pandemic on 11 March 2020 as it affect more than 200 countries globally. Covid-19 pandemic caused profound changes across the world, even on day today activities of lives of the survivors. Hence the present study is an attempt to unravel the impact of COVID-19 on quality of life among COVID-19 survivors.</p><p><strong>Objectives:</strong>To explore post physical, psychological and social wellbeing among COVID-19 survivor with and without co-morbidity and association between Quality of Life of COVID-19 survivors with selected Socio-demographic Variables.</p><p><strong>Method:</strong> A non-experimental, exploratory survey research approach was used for the present study. Ethical clearance was obtained from institutional ethical committee of Sri DevarajUrs College of Nursing, Kolar. Through non-probability Snowball sampling techniques, 191 COVID 19 survivors who full filled the inclusion criteria were selected andassessed through 36-Item Short Form Health Survey questionnaire on Quality of Life (QOL).</p><p><strong>Results:</strong>Study revealed that, majority (69%) of COVID 19 survivors had fair quality of life, 6% of them were having good quality of life and 25% of them were having poor quality of life. The study concluded that, even though COVID-19 survivors had good social health, they were having fair physical health and poor psychological health.</p><p><strong>Conclusion:</strong>Psychological impact of covid-19 pandemic calls for planning of counselling services to improve mental health among COVID-19survivors.</p><p> </p&gt
