The asymmetric unit of the title compound, [Li(4)(C(6)H(2)N(2)O(4))(2)(H(2)O)(6)](n), comprises two Li(+) ions bridged by a completely deprotonated pyrimidine-3,6-dicarboxyl-ate ligand and coordinated by two water mol-ecules; the asymmetric units related by an inversion operation create a structural unit which forms part of a two-dimensional polymeric structure parallel to (10-1). One of the Li...

Free-falling objects impacting onto water pools experience a very high initial impact force, greatest at the moment when breaking through free surface. Many have intuitively wondered whether throwing another object in front of an important (like oneself) before surface may reduce this force. Here, we test idea experimentally by allowing two spheres to consecutively enter and measuring forces on...

The airflow physics in the cavity during entry of a symmetric wedge into water are investigated experimentally using flow visualization techniques and particle image velocimetry (PIV) measurements. spatial temporal evolutions velocity presented. Smoke indicates some small-scale phenomena like secondary vortexes, free shear layers, Kelvin–Helmholtz (K-H) instabilities within cavity. information ...

The title compound, C(16)H(20)N(4)O(3)S·0.25CH(4)O·0.25H(2)O, is a hydrate/methanol solvate of torasemide, a diuretic drug used in the treatment of hypertension. The asymmetric unit contains two torasemide mol-ecules and half-occupied methanol and water mol-ecules. It is isomorphous with the previously reported nonsolvated T-II form of torasemide. The water mol-ecules contribute to the stabilit...
