Role of microalgae in dye degradation – a comparative report

Abstract :

A stA stochastic model, two state Markov Chain, was applied to HAV seroprevelance data by age group from the Six Primary Health Centres (PHCs) viz., Thirukkattupalli, Kurungulam, Pillaiyarnatham, Kudikadu, Kovilvenni and Budalur of the Thanjavur District, Tamil Nadu, South India. Age specific Risk Rate, Markov Risk Rate, (MRR) and its weighed sum, Total MRR were defined and used as novel measures to prioritize age groups for allocating vaccine and to decide in which PHC regions vaccine should be used to prevent Hepatitis A. All age groups whose MRR was over 20 are strongly recommended to be vaccinated first. Pillaiyarnatham and Budalur were predicted to be the PHC regions with a high risk of hepatitis A virus epidemic and therefore suggested that they should be under close surveillance.
