  • The minimum number of colors needed for a dominated coloring of G is called the dominated chromatic number of G, denoted by χdom (G). In this paper, dominated coloring of graphs is compared with (open) packing number of G and it is shown that if G is a graph of order n with diam(G) ≥ 3, then χdom(G) ≤ n − ρ(G) and if ρ0(G) = 2n/3, then χdom(G) = ρ0(G).

  • As reported in the financial statements of each AMC, fund expenses can be divided into management fees and administrative fees. Expense ratio is the ratio between total fund expenses to fund’s assets. Administrative or operating expense excluded management fees of AMCs managing large number of funds are considered to be constant. Thus, when management fee is excluded, fund expense ratio is lower. Fund expenses excluded management fees indicate fund operation efficiency. Management fees measures security selection skills of fund manager.

  • All limited firms in Sweden are legally bound to submit an annual report to the Swedish Patent and Registration Office (PRV). This study uses data collected from MM (Market Manager)-Partner, now merged with PAR, a Swedish consulting firm that gathers economic information from PRV. This information is primarily used by decision-makers and stakeholders in Swedish commercial life. Our data comprise all Swedish limited companies active at some point between 1997 and 2005, in total 288,757 firms, and include all variables that can be found in the annual reports, e.g.

  • 11 Halogens, Sulfur, Metals, and Metalloids specific trace elements. A thorough, updated review of the scientific literature is recommended for project design. A number of substances are considered measures of water quality, but are seldom of concern as pollutants to be treated in constructed wetlands. These include common metals (e.g., sodium, potassium, calcium, and magnesium) as well as halogens (e.g., fluorine, chlorine, bromine, and iodine). Together with sulfate, these compounds often dominate the total ion content of natural waters and wastewaters.

  • By comparison, the independent design profession in France is relatively new, with 53% of organisations operating for fewer than 10 years. The sector is dominated by a small number of large agencies. Automotive, aerospace and engineering companies tend to use in-house designers whereas luxury companies tend to use international agencies for brand development and corporate communications. The Swedish design sector has an estimated total of 11,199 companies, with many operating as sole-traders.

  • The dominant isolates and isolates with broad-spectrum antagonistic activity were identified by 16S rRNA-based sequence analysis. Results showed that colony counts, total number of species, and the number of bioactive species of actinobacteria in saxicolous lichens were higher in elevation 3000 m. The dominant isolates were classified into 42 species of 10 genera. Antagonistic activities were detected in approximately 66% of the actinobacteria isolates.
