Abstract: Hydrogen fuel cell usage has been seen as a great approach as a pollution-free alternative to using fossil fuels which makes water by combining hydrogen and oxygen. In this way, they generate electricity. There is a problem with fuel cells for obtaining hydrogen. Molecules like water and alcohol have to be processed to extract hydrogen to feed into a fuel cell. Some of these processes require using other energy sources, which then defeat the advantages of this "clean" fuel. Scientists have come up with ways to make power laptops and few small devices with fuel cells as an advancement in technology, and some car companies are promising that soon they will be seeing cars that emit nothing but clean water. H power is renowned for the highest level of quality, innovation, and design. For twenty years H power has created glorious motorcycles, known for their excellent performance and unrivaled engineering. This paper results in a comprehensive survey to know the role played by hydrogen in t

Abstract: The present study was undertaken with an aim to evaluate the effectiveness of abdominal ultrsonography (USG) in the diagnosis of palpable abdominal mass and compare the results of USG with those of other method; whether USG can increase the diagnostic yield in case of palpable abdominal masses in paediatric age group and their consistency with histopathological diagnosis. For this purpose 30 cases were selected having palpable abdominal masses in different sites, age ranging from 6 months to 12 years. The results suggested that the predominance of male over female in the ratio of 3:2. In this study confirms that Wilm’s tumor accounted for 30.00%. In this study the sensitivity of ultrasonogram is 96.30% and the specificity is 60.00%. The positive predictive value is 92.86% and negative predictive value is 75.00% and the overall diagnostic accuracy of this series is 90.62%. In this study false positive rate of ultrasonogram diagnosis is 6.66% and false negative rate of ultrasonogram di
