FRAMEWORK FOR MATERNAL MORBIDITY AND MORTALITY INTERVENTIONS IN ETHIOPIA: A SYSTEMATIC REVIEW PROTOCOL


High performance liquid chromatography preparation of the molecular species of GM1 and GD1a gangliosides with homogeneous long chain base composition.

A semi-preparative, analytical high performance liquid chromatographic (HPLC) procedure is described for the isolation of molecular species of GM1 and GD1a gangliosides containing a single long chain base, C18 or C20 sphingosine, C18 or C20 sphinganine, each in its natural erythro or unnatural Film-Memory threo form.The threo forms were obtained fr

The morphology control and mechanical properties of nanoporous Ag

In the present work, nanoporous Ag (np Ag) ribbons are prepared by Gift Card chemical etching Cu60-xAg40Lax (x = 0, 3, 6 at.%) precursor alloys.The effects of precursor crystal structure on the morphology and mechanical properties of nanoporous Ag (np Ag) ribbons are investigated.The addition of La element inhibits the nucleation and growth of the
