movement of ions, organic solutes and water across the epithelium, but what drives transport is ultimately metabolism. The latter has not received much attention in studies of epithelial transport. However, metabolism and transepithelial transport must be intimately coupled, especially in actively transporting epithelia, such as Malpighian tubules. Indeed, in Malpighian tubules of the yellow fe...

By using a solvent-based method composites of ethylenevinyl acetate copolymer and carbon black (EVA-CB) were synthesized for sensing BTEX (benzene, toluene, ethylbenzene and xylene) vapours. The composites were characterized using atomic force microscopy (AFM) in an electroconductive mode. Gas sensing results show that EVA-CB can reproducibly detect BTEX and that the response increases linearly...

The first direct measurements of effective magnetic diffusivity in turbulent flow of electroconductive fluids (the so-called β effect) under the magnetic Reynolds number Rm≫1 are reported. The measurements are performed in a nonstationary turbulent flow of liquid sodium, generated in a closed toroidal channel. The peak level of the Reynolds number reached Re≈3×10(6), which corresponds to the ma...
