  • 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.

  • 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.

  • Studies of the composition and density of phytoplankton and the water quality of Nhu Y river were conducted over six months (March to August 2011). Phytoplankton samples were collected by filtration and immediately preserved in Lugol’s solution. The phytoplankton species composition recorded 117 species belonging to six divisions: Cyanobacteria (24 taxa), Bacillariophyta (14 taxa), Chlorophyta (45 taxa), Euglenophyta (31 taxa), Cryptophyta (2 taxa), and Dinophyta (1 taxa), of which Chlorophyta and Euglenophyta were dominant in terms of species numbers.

  • A plant’s microbiota has various implications for the plant’s health and performance; however, the roles of many microbial lineages, particularly Archaea, have not been explored in detail. In the present study, analysis of archaea-specific 16S rRNA gene fragments and shotgun-sequenced metagenomes was combined with visualization techniques to obtain the first insights into the archaeome of a common salad plant, arugula (Eruca sativa Mill.).

  • Castor is a non-edible oilseed crop, primarily grown for oil containing an unusual hydroxy fatty acid and ricinoleic acid (80–90%) of the total fatty acids. Commercial exploitation of heterosis in castor was successful in India due to the development of stable pistillate lines from a dominant and epistatic “S” type pistillate source. Diversification of pistillate sources using NES and other new sources necessitated the need for identification of diverse male combiners among the existing pool of male combiners.

  • The present investigation highlighted the facultative mutualistic association of six ant species, viz. Camponotus parius Emery, Meranoplus bicolor Guerin-Meneville, Paratrechina longicornis Latreille, Monomorium dichroum Forel, Technomyrmex albipes Smith and Oecophylla smaragdina Fabricius (Hymenoptera: Formicidae) belonging to three sub-families (Formicinae, Myrmicinae and Dolichoderinae) with lac insect (Kerria lacca Kerr) on host plants, Flemingia semialata. Out of these, Technomyrmex albipes was the most abundant and dominated species which constituted 76.66 percent (394.8 no.

  • The present investigation was undertaken with a view to generate genetic information on gene effects for 14 quantitative traits in brinjal through generation mean analysis. The experimental material consists of six generations, namely P1, P2, F1, F2, B1 and B2 of four crosses in brinjal viz., AB-15-07 x GJLB-4 (cross 1), JBR-14-07 x Pant Rituraj (cross 2), NSR-01 x Swarnmani Black (cross 3) and NBR-14-05 x GJB-03 (cross 4). The results indicated that the magnitude and type of gene effects differed for the same trait in different cross combinations.

  • Madhya Pradesh is pre-dominated by the Tribal population. The differences in the tribal community, spread over in various parts of the state, is clearly seen not only on the basis of their heredity, lifestyle and cultural traditions, but also from their social, economic structure, religious beliefs and their language and speech. Due to the different linguistic, cultural and geographical environment, and its peculiar complications, the diverse tribal world of Madhya Pradesh has been largely cut-off from the mainstream of development. The population of Tribals in Madhya Pradesh is 122.

  • The present investigations were carried out to estimate the genetic components of variation for yield and its contributing traits in sponge gourd. Genetic components D^ , H^ 1 and H^ 2 were significant for days to first male flower anthesis, node number of first male flower, days to first female flower anthesis, node number of first female flower, fruit length, fruit weight, number of fruits per plant, main vine length and total yield except D^ in case of number of primary branches which indicate the importance of both additive and dominant gene effects in regulating these traits.

  • The purpose of this study was to assess seasonal variations in bacterial community composition in Tapi River. Samples from three selected sites along the Tapi River stretch were collected and analyzed for various physico-chemical properties as well as microbial load and composition of bacterial communities. The number of total viable counts as well as bacterial isolation and identification were done by using Bergey’s Manual of Determinative Bacteriology.

  • This study was conducted to enhance the understanding of phytoplankton diversity of Duyen Hai town, Tra Vinh province. We selected 12 representative sampling sites and investigated phytoplankton diversity in both dry and rainy seasons. The phytoplankton of this area were comprised of 134 species, belonging to 64 genera, 45 families, 31 orders, 8 classes and 5 divisions. Among those divisions, Bacillariophyta was the most dominant in species, accounting for 70% of the total number of species and Cyanobacteria commonly had high density at 12 surveyed sites.

  • The ichthyo-fauna in the Ba Che and Tien Yen rivers, northern Vietnam is highly diverse, with a total of 245 species determined. However, data on the distribution of fish species are not sufficiently provided for the whole area. This study was conducted from 2008 to 2011 at 27 stations from the Ba Che and Tien Yen river basins to determine the distribution of fish species according to different sections of the rivers, water bodies, seasons, and salinity levels.
