This paper analyzes a certain class of combinatorial board games that includes Ayo, Tchoukaillon and Modular N–queen. We refine the existing results by providing simple and intuitive proofs using abstract combinatorics, and also reveal some interesting game positions.
متن کاملMetals and Non-metals
Ductile: Substances that can be drawn into thin wires are called ductile. For example, most of the metals are ductile. Question 2: Why is sodium kept immersed in kerosene oil? Answer: Sodium and potassium are very reactive metals and and combine explosively with air as well as water. Hence, they catch fire if kept in open. Therefore, to prevent accidental fires and accidents, sodium is stored i...
متن کاملChemistry of carcinogenic metals.
The periodic distribution of known and suspected carcinogenic metal ions is described, and the chemical behavior of various types of metal ions is explained in terms of the general theory of hard and soft acids and bases. The chelate effect is elucidated, and the relatively high stability of metal chelates in very dilute solutions is discussed. The concepts employed for the chelate effect are e...
متن کاملModification of various metals by volume discharge in air atmosphere
The results of the modification of stainless steel, niobium and titanium by volume discharge induced by a beam of runaway electrons in air under normal pressure are presented. Changes in the chemical composition of the surface layers of metal by the action of the discharge, structural changes and changes of hardness were studied. It has been found that the concentration of oxygen and carbon in ...
متن کاملVIII-Metals-J-Corrosion protection-1_ CORROSION PROTECTION OF METALS
Nearly all metals, with the exception of gold and platinum, will corrode in an oxidising environment forming compounds such as oxides, hydroxides and sulphides. The degradation of metals by corrosion is a universal reaction, caused by the simple fact that the oxide of a metal has a much lower energy than the metal itself. Hence there is a strong driving force for the oxidation of metals. For ex...
