New Information on the Na-Ti-Se Ternary System

Z. Naturforsch. 56 b, 49-56 (2001); received August 22, 2000 Molten Salt Fluxes, Polychalcogenide, Polyselenide Na2Ti2Se9 was first discovered in the quaternary system Na/Ti/P/Se, but it can be prepared rationally by dissolving Ti in a Na2Se.v flux at 375 °C. The silverish dark red crystals are airand water-stable. A new method for synthesizing Na4TiSe4 is also reported. Na2Ti2Seg crystallizes ...

Healing of complement activating Ti implants compared with non-activating Ti in rat tibia.

Recent studies have revealed that ozone ultraviolet (UVO) illumination of titanium (Ti) implants improves bone-implant anchorage by altering the physico-chemical and immune activating properties of the titanium dioxide (TiO(2)) layer. In the present rat tibia model, the authors compared the early events of inflammation and bone formation around UVO-treated Ti and complement activating immunoglo...

Non-deterministic Matrices and Modular Se- mantics of Rules

We show by way of example how one can provide in a lot of cases simple modular semantics for rules of inference, so that the semantics of a system is obtained by joining the semantics of its rules in the most straightforward way. Our main tool for this task is the use of finite Nmatrices, which are multi-valued structures in which the value assigned by a valuation to a complex formula can be ch...
