The cheap and easy availability of the Kinnow peel waste has reported various applications due to presence of multifunctional groups. Therefore, in present study we explored its application to synthesize N-Benzylideneaniline and its derivatives based on Schiff base reaction. Kinnow peel powder is characterized by FTIR, TEM, SEM, XRD, EDX, and TGA for functional groups, morphology, surface, elements and thermal stability. Benzaldehyde, aniline, and their derivatives such as 4-methyl benzaldehyde, 4-hydroxy benzaldehyde, 4-methoxy benzaldehyde, and 4-methoxy aniline have been used to compare the efficacy of the Schiff base reaction using analysis of variance (ANOVA) and it has been observed that combination of Aniline and benzaldehyde for Schiff base reaction provided 85% yield of relative product.
The concept of length-biased distribution can be employed in development of proper models for life-time data. In this paper, we develop the length-biased form of Weighted Maxwell distribution (WMD). We study the statistical properties of the derived distribution including moments, moment generating function, hazard rate, reverse hazard rate, Shannon entropy and estimation of parameters.
COVID-19 (Corona Virus Disease of 2019) what is known to be first incidence from Wuhan, China has now discovered its spread & threat to every other country. Protective measurements and better addressing policies seem to be the only way of fighting against COVID-19 progression till the vaccination to be invented. Study aims at finding the estimated progression of COVID-19 spread in India at different rates of transmission (R 0) by using Susceptible, Exposed, Infected, Recovered (SEIR) model using online data COVID-19 registered cases in India collected from 30th January 2020 to 28th April 2020 for earlier phase of the research & then till June 30th 2020 for later part of the study. Also the data of around 206 countries for BCG vaccine coverage & 155 countries for temperature effect were assessed for finding correlation with COVID-19 morbidity. Reproduction number for COVID-19 for India was found at R 0 =2.51 with transmission rate (b) = 0.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
