Journal of Materials Research and Technology, 2020 This research communication deals with the steady, incompressible two-dimensional (2D) nonlinear mixed/forced convective flow of Williamson fluid towards a flat and stretchable surface of sheet. The flow is discussed in semi-infinite domain and generated

Role of diatoms in the spatial-temporal distribution of intracellular nitrate in intertidal sediment. [PDF]
PLoS ONE, 2013 Intracellular nitrate storage allows microorganisms to survive fluctuating nutrient availability and anoxic conditions in aquatic ecosystems. Here we show that diatoms, ubiquitous and highly abundant microalgae, represent major cellular reservoirs of ...

Lateral-drag propulsion forces induced by anisotropy
Scientific Reports, 2017 We predict the existence of lateral drag forces near the flat surface of an absorbing slab made of an anisotropic material. The forces originate from the fluctuations of the electromagnetic field, when the anisotropy axis of the material forms a certain ...

Examining the spatial and temporal variation of groundwater inflows to a valley-to-floodplain river using 222Rn, geochemistry and river discharge: the Ovens River, southeast Australia [PDF]
Hydrology and Earth System Sciences, 2013 Radon (222Rn) and major ion geochemistry were used to define and quantify the catchment-scale groundwater-surface water interactions along the Ovens River in the southeast Murray–Darling Basin, Victoria, Australia, between September 2009 and October 2011.

Statistical Mechanics of Thin Spherical Shells
Physical Review X, 2017 We explore how thermal fluctuations affect the mechanics of thin amorphous spherical shells. In flat membranes with a shear modulus, thermal fluctuations increase the bending rigidity and reduce the in-plane elastic moduli in a scale-dependent fashion ...
