Abstract Globally ice-covered oceans have been found on multiple moons in the solar system and may also a feature of Earth’s past. However, relatively little is understood about dynamics these oceans, which affect not only physical environment but any potential life its detectability. A number studies simulated circulation icy-world come to seemingly widely different conclusions. To better unde...

Using two-dimensional simulations of non-radiative viscous rotating black hole accretion flows, we show that the flows with α ∼ 0.1 − 0.3 self-organize to form stationary unipolar or bipolar outflows accompanied by global meridional circulations. The required energy comes, with efficiency ∼ 0.001 − 0.01, from the matter directly accreted onto black hole. Observational implications are discussed.

Clincial cases of malaria infection during pregnancy may result in placental1-5 and/or congenital malaria infections. Emerging evidence has also shown that pregnant women could remain asymptomatic with malaria parasitaemia6. Hence, this study was designed to assess the possible impact of asymptomatic maternal peripheral malaria parasitaemia and Plasmodium falciparum specific-IgG during pregnanc...

Surface inhomogeneities, including boundaries between different types of vegetations and land use patterns, have important effects on the structure of the atmospheric boundary layer. Changes in the surface roughness, temperature and wetness make the planetary boundary layer (PBL) nonhomogeneous and produce substantial horizontal gradients of boundary layer properties. Significant differences in...
