Using the AAOmega instrument of the Anglo-Australian Telescope, we have obtained mediumresolution near-infrared spectra of 10,500 stars in two-degree fields centered on the galactic globular clusters 47 Tuc, NGC 288, M12, M30 and M55. Radial velocities and equivalent widths of the infrared Ca II triplet lines have been determined to constrain cluster membership, which in turn has been used to s...

Abstract: Bottom ash is a hazardous by-product from coal based thermal power plants. In this study fine aggregate in concrete mix has been replaced with bottom ash and glass fibre is additionally used to enhance the strength characteristics of concrete. The concrete mix design is done for M30 grade concrete. The mix is prepared for different combinations of 0%, 30%, 40%, 50% and 100% of replace...

In this paper we demonstrate how the global dynamics of an economic model can be analyzed. In particular, as an application, we consider a market share attraction model widely used in the analysis of interbrand competition in marketing theory. We analyze the local and global dynamic properties of the resulting two-dimensional noninvertible dynamical system in discrete time. The main result of t...

Small number statistics may heavily affect the structure of the broadening function in integrated spectra of galactic globular cluster centers. As a consequence, it is a priori unknown how closely line broadening measurements gauge the intrinsic velocity dispersions at the cores of these stellar systems. We have tackled this general problem by means of Monte Carlo simulations. An examination of...

The disposal of used tires is a major environmental problem throughout the world which causes environmental hazards. Crumb rubber is a waste material that is ideal for use in concrete applications. The aim of this study is achieved to use of rubber waste as partial replacement of fine aggregate to produce rubberize concrete in M30 mix. Different partial replacements of crumb rubber (0, 5, 10, 1...

Electronic waste is major threats to the human health and environment. The disposal of in nature affects humans animals. construction industry will reduce natural disorders by utilization E-waste. current study focused on attributes strength durability. M30 grade concrete mixes, electronic (0%, 4%, 8%, 10%,12%) replaced coarse aggregate fly ash cement same % evaluated compressive strength, spli...
