- ItemReal visualization of molecules in physics and chemistry lessons at primary and secondary schools(Czech Society of Chemical Engineering, 2014-01-01) Košek, Ondřej; Vyskočil, Jaroslav; Jodas, BořivojThe present article describes the potential use of molecular projection in chemistry and physics lessons. Beginnig of the text we point to the students´ Spatial imagination of students and the advantages of the real and computer molecular projection are discussed. Practical experience, ideas for work with molecular construction sets and several worksheets for students are added. © 2014, Czech Society of Chemical Engineering. All rights reserved.
- ItemRemarks on restrained domination and total restrained domination in graphs(Czech Society of Chemical Engineering, 2005-01-01) Košek, Ondřej; Vyskočil, Jaroslav; Jodas, Bořivoj; Zelinka, BohdanThe restrained domination number γ r(G) and the total restrained domination number γ t r (G) of a graph G were introduced recently by various authors as certain variants of the domination number γ(G) of (G). A well-known numerical invariant of a graph is the domatic number d(G) which is in a certain way related (and may be called dual) to γ(G). The paper tries to define analogous concepts also for the restrained domination and the total restrained domination and discusses the sense of such new definitions. © Mathematical Institute, Academy of Sciences of Czech Republic 2005.
