This paper examines numerically the combined effects of double diffusive mixed convective flow and higher order chemical reaction in Darcy porous medium over a rotating vertical cone. The governing equations for flow, energy and concentration are transformed into ordinary differential equation by using similarity transformation and are solved numerically by employing the fourth order Runge - Kutta method with shooting technique for different parametric values. The effects of mixed convection parameter, inverse Darcy number, and order of homogeneous chemical reaction, buoyancy ratio and chemical reaction parameter are investigated and reported graphically on velocity, temperature and concentration profiles together with the local Nusselt and Sherwood numbers. The numerical results are obtained for the mixed convection parameter varying as [0.5 ≤ gs ≤ 10] , inverse Darcy number varying as [0.5 ≤ Da-1 ≤ 3] , order of homogeneous chemical reaction varying as [1 ≤ n ≤ 4], chemical reaction parameter [-1.5 ≤ γ ≤ 3.5] and the buoyancy ratio [-0.5 ≤ N ≤ 1], while the Prandtl number is considered fixed at [Pr = 0.71].Comparison with previously published numerical work is performed and a good agreement between the results is observed. It is found that the increase in the chemical reaction parameter leads to reduce the tangential velocity and concentration profiles while, it increases the circumferential and normal velocity and temperature profiles. The results indicated that the skin-friction coefficients and the Nusselt and Sherwood numbers are strongly dependent on the buoyancy ratio. Moreover, both the local Nusselt and Sherwood numbers increase when the mixed convection parameter and the buoyancy ratio increase. Application of the present study includes rotating heat exchangers, spin stabilized missiles, packed-bed chemical reactors in geothermal and geophysics.Keywords

A patent is an important source of scholarly information and forms a link for scholarly communication in any discipline. The role played by and the influence of patents on scientific invention and innovation has become integral part of R&D, Product development, marketing and many scientific and commercial activities. The purpose of this paper is to analyze the citations for the popular journal called Scientometrics available in the patents issued by the United States Patent and Trademark Office (USPTO). This study provides an overview on the importance of patent citations to scientific journals and provides the citations from the patents available in the USPTO database for Scientometrics Journal, a journal in the field of Library and Information Science (LIS) and Scholarly metrics. This study identifies to what extent the articles from the Scientometrics journal are used and cited by inventors of the patents in the USPTO. We analyzed the patent citations to Scientometrics. The results show that the total number of core patent citations to Scientometrics journal papers on the USPTO were 53 out of 64 retrieved results. The technical papers (or technology-oriented papers) related to various scientific, technical, the World Wide Web, and search engines published in Scientometrics journal attracted more citations from patents.Keywords
