The second paper of the series about Ampharetidae from Japan includes twelve species of four genera with elevated and modified notopodia, Anobothrus Levinsen, 1884, Sosane Malmgren, 1866 (including species of the synonymized genera Muggoides Hartman, 1965, Sosanopsis Hessle, 1917, and Genus A sensu Uebelacker 1984), Tanseimaruana gen. nov., and Zatsepinia Jirkov, 1986. Tanseimaruana gen. nov. i...

The effect of heat transfer on unsteady MHD couette flow between two infinite parallel porous plates in an inclined magnetic field has been investigated. The lower plate is considered porous. The governing equations of the flow field are solved by variable perturbation technique and the expression for the velocity and temperature are obtained. The effects of various parameters such as Hartman n...

Fix integers n ≥ r ≥ 2. A clique partition of ( [n] r ) is a collection of proper subsets A1, A2, . . . , At ⊂ [n] such that ⋃ i ( Ai r ) is a partition of ( [n] r ) . Let cp(n, r) denote the minimum size of a clique partition of ( [n] r ) . A classical theorem of de Bruijn and Erdős states that cp(n, 2) = n. In this paper we study cp(n, r), and show in general that for each fixed r ≥ 3, cp(n, ...

This research aims to investigate thermal and flow behaviors entropy generation of magnetohydrodynamic Al2O3-Cu/water hybrid nanofluid in a lid-driven cavity having two rounded corners. A solver based on C ++ object-oriented language was developed where the finite volume used. Parameter’s analysis is provided by varying Reynolds numbers (Re), Hartmann (Ha), fraction (ϕ), radii The findings show...
