The heat and mass transfer of an steady three dimensional natural convection flow of a viscous incompressible fluid between two vertical walls filled with porous materials is investigated. The temperature of the plate is assumed to be fluctuating cosinusoidally. The governing equations in non-dimensional form are solved by using the perturbation technique. Approximate solutions are derived for Velocity, Temperature and Concentration field. The effect of various non dimensional parameters on Velocity field, Temperature field, Concentration field, skin friction and Nusselt number, are studied numerically.Keywords

Present study on diversity of coccinellid beetles comprises a significant group of predatory beetles which are being utilized in biological control of insect pests from more than one hundred years ago throughout the world. An extensive survey and collection of coccinellid beetles was carried out by following the sweep net and handpicking method during a period of two years, June 2016 to May2018, in Uttarakhand, India. Collection of beetles was also made at different altitudes. All the collected beetles have been identified up to species level. In total, fifteen species of coccinellid beetles were identified as Aiolocaria hexaspilota (Hope), Anegleis cardoni (Weise), Brumoides suturalis (Fabricius), Coccinella septempunctata Linnaeus, C. transversalis Fabricius, Harmonia dimidiata (Fabricius), Henosepilachna vigintioctopunctata (Fabricius), Hippodamia variegata (Goeze), Illeis confusa Timberlake, Menochilus sexmaculatus (Fabricius), Micraspis allardi (Mulsant), Micraspis univittata (Hope), Oenopia sexareata (Mulsant), Platynaspidius saundersi (Crotch) and Propylea dissecta (Mulsant). H. vigintioctopunctata is phytophagous while I. confusa is mycophagous; all other species are predatory feeding on mealy bugs and aphids occurring on forest tree species. Out of all identified species, four species A. hexaspilota, I. confusa, O. sexareata and P. saundersi have been recorded for the first time from Uttarakhand.Keywords
