An LRS Bianchi type-V cosmological models representing a viscous fluid distribution with a time dependent cosmological term Λ is investigated. To get a determinate solution, the viscosity coefficient of bulk viscous fluid is assumed to be a power function of mass density. It turns out that the cosmological term Λ(t) is a decreasing function of time, which(More)
FRW models of the universe have been studied in the cosmological theory based on Lyra’s manifold. A new class of exact solutions has been obtained by considering a time dependent displacement field for variable deceleration parameter from which three models of the universe are derived (i) exponential (ii) polynomial and (iii) sinusoidal form respectively.(More)
Up to one third of the total annual global production of grain (cereals, oil seeds, and pulses) is lost primarily due to poor post-harvest management. Lack of control over grain moisture content, temperature and insect infestations are the three most significant factors causing this loss. High grain moisture and temperature provide favorable conditions for(More)
The GLI3 protein is a zinc finger transcription factor, expressed early in development. The GLI3 gene exhibits allelic heterogeneity as mutations in this gene are associated with several developmental syndromic and non-syndromic polydactyly. The present study reports two cases: first, a familial case of Greig Cephalopolysyndactyly Syndrome (GCPS); the(More)
