Convex universal fixers
In [1] Burger and Mynhardt introduced the idea of universal fixers. Let G = (V,E) be a graph with n vertices and G a copy of G. For a bijective function π : V (G) → V (G), define the prism πG of G as follows: V (πG) = V (G)∪ V (G) and E(πG) = E(G)∪E(G′)∪Mπ, where Mπ = {uπ(u) | u ∈ V (G)}. Let γ(G) be the domination number of G. If γ(πG) = γ(G) for any bijective function π, then G is called a un...
متن کاملPhysically-based Animation of Water Pollutant Diffusion
We present a physically-based animation method for simulating the diffusion of water pollutant in this paper. Our method allows animating the dynamic evolution of biological pollutants (e.g., water hyacinth, algae) on largescale water surface effectively. To enable the simulation of such a phenomenon in large scale virtual environment, we simplify the problem by considering the water pollutants...
متن کاملSome Experiments with Chromium Compounds as Fixers for Electron Microscopy
In the course of experimentation with various tissue fixations other than Os04 it was noticed that mixtures containing chromium compounds showed considerable promise. Therefore the fixation characteristics of three such compounds, CrC13, K2Cr~07 and Cr08 (the anhydride of H2Cr04), were systematically investigated. Although the action of all three was essentially similar, CrO~ proved to be the m...
متن کاملCharacterizing Cartesian fixers and multipliers
Let G H denote the Cartesian product of the graphs G and H. In 2004, Hartnell and Rall [On dominating the Cartesian product of a graph and K2, Discuss. Math. Graph Theory 24(3) (2004), 389–402] characterized prism fixers, i.e., graphs G for which γ(G K2) = γ(G), and noted that γ(G Kn) ≥ min{|V (G)|, γ(G)+n−2}. We call a graph G a consistent fixer if γ(G Kn) = γ(G)+n−2 for each n such that 2 ≤ n...
متن کاملRemoval of pollutant heterocyclic dyes from water with ZnO adsorbent
In this study, Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by t...
