Identification of Stellar Sequences in various Stellar Systems : ESO65-SC03, TEUTSCH 106, TURNER 6

The spatial morphological study of studied clusters is carried out through the identified probable members within them. The field stars decontamination is performed by the statistical cleaning approach (depends on the magnitude and colour of stars within the field and cluster regions). The CMRD (colour magnitude ratio diagram) approach is used to separate stellar sequences of the cluster systems. The age, distance and reddening of each cluster are estimated through the visual inspection of best fitted isochrone in colour magnitude diagrams(CMDs). The mean proper motion values of clusters are obtained through the extracted data from PPMXL and UCAC4 catalogs. Moreover, these values are varying according to the extracted data-set from these catalogues. This variation is occurred due to their different estimation efficiency of proper motions. The TCR (two colour ratio) and TCMR (two colour magnitude ratio) values of each cluster are determined by utilizing the WISE and PPMXL catalogues, these values are found abnormal for TEUTSCH 106. In addition, the TCMR values are similar to TCR values at longer wavelength, whereas both values are far away to each other at shorter wavelength. The fraction of young stellar objects (YSOs) is also computed for each cluster.Comment: 24 pages, 5 figure

Marketing of Library Services and Products through Social Media: An Evaluation

Social media has a great impact on information promotional activities by bringing tremendous changes in the field of marketing. Social networking applications help the users to possess interconnections among the community members and remix the library services and products to brand them visible in a broader way. This paper gives an overview of the concept of marketing of library services and products in the pretext of handiness of social networking technologies (SNT). The paper also discusses various social networking sites (SNS) such as Facebook, Twitter, Delicious, Youtube, Flickr etc. An outline of how the social media may successfully be applied to enhance the effectiveness in marketing library services and products is observed. Relative merits and challenges with adoption of SNS are also examined

Formulas for cubic partition with 3-cores

Let C3(n) denote the number of cubic partitions of n with 3-cores. In this paper, we establish the arithmetic properties and formulas for C3(n) by employing Bailey's �66 formula and theta function identities. © 2017 Elsevier Inc

Proximate Composition, Chlorophyll a, and Carotenoid Content in Dunaliella salina (Dunal) Teod (Chlorophycea: Dunaliellaceae) cultured with Cost-Effective Seaweed Liquid Fertilizer Medium

Growth, proximate composition, chlorophyll a, and carotenoid content were estimated in static cultures of micro alga Dunaliella salina (Dunal) Teod (Chlorophycea: Dunaliellaceae) to compare the quality and quantity of biomass produced with seaweed liquid fertilizer (SLF) against Walne’s medium. Culture of micro algae was performed with controlled temperature of 27 ± 1 °C, salinity of 33, and an irradiance of 120 ± 3 μ mol m–2 s –1, and daily samples were taken to estimate the above-mentioned parameters. Mean cellular density from samples of both medium were similar and growth rates were 0.44 and 0.42 doubling per day, respectively. Maximum values of protein content 5.2 and 5.5 pg per cell were estimated on day 5 in Walne’s medium and SLF, respectively. Carbohydrate and lipid content decreased during the first 4 days corresponding to the culture exponential growth. Higher carbohydrate content was found in both media during the first 2 days and thereafter reduced partially compared to their concentrations. Generally lipid contents in cultures with SLF were significantly higher (P ≤0.05) compared to Walne’s medium. Both pigments also increased exponentially and their concentration was same in both experiments. In conclusion, all the parameters tested were similar when using either media, and hence SLF can be used as an alternate media for micro algal culture

Basic Parameters of Open Star Clusters DOLIDZE 14 and NGC 110 in Infrared bands

The basic physical parameters of a poorly studied open cluster NGC 110 and an unstudied open cluster DOLIDZE 14 are estimated in the present study using the archival PPMXL and WISE catalogues. The radius of both the clusters are estimated by fitting the modified King's empirical model on their stellar density profiles. The other basic parameters of the clusters such as distance, reddening, and age are obtained by visual fitting of the Marigo's solar metallicity isochrone on their IR colour-magnitude diagrams (CMDs). The mean-proper motion of the clusters are estimated through the individual proper motion of probable members identified through the dynamical and statistical methods. The archival catalogues (JHKW1W2) are constructed for both the clusters by compiling the extracted data from the PPMXL and WISE catalogues. The various colour-excesses, such as E(J-H), E(H-K) and E(W1-W2), are estimated using the best fit theoretical isochrone on the (J-H)-H, (H-K)-H and (W1-W2)-H CMDs, respectively. The ratios of various infrared colours of the clusters are obtained through their two-colour diagrams. We also identify the most probable members in these clusters by estimating spatial, kinematic and spatio-kinematic probabilities of stars within the cluster. A correlation between the E(H-K) and E(W1-W2) is also established.Comment: 23 pages, 7figure
