A Study On Impact Of Leverage On The Profitability & Risk Of The Indian Steel Industry

The steel industry is the booster of any economy and it can be called as match-winner in the process of developing an economy or society. The steel industry is a crucial industry for the industrial revolution in this globalized economy and assessment of the risk and profitability of the steel industry is very important to create a strong path for the future economy. Capital investments are very high in the Steel industry and the sources of capital are equity and debt. All the stack holders should know the risk and profitability of the steel industry. To assess the impact of leverage on the profitability operating leverage, financial leverage, combined leverage, and EPS is used

Topological indices of Sierpiński Gasket and Sierpiński Gasket Rhombus graphs

Sierpiński graphs S(n, k) were defined originally in 1997 by Sandi Klavžar and Uroš Milutinović. In this paper atom bond connectivity index, fourth atom bond connectivity indices, geometric arithmetic index, fifth geometric arithmetic indices, augmented Zagreb index and sankruti index of Sierpiński Gasket graphs and Sierpiński Gasket Rhombus graphs are determined.The first author is supported by University Grants Commission, Government of India, for the financial support under the Basic Science Research Fellowship.UGC vide No.F.25 − 1/2014 − 15(BSR)/7 − 349/2012(BSR), January 2015.The Second author is partially supported by the University Grants Commission for financial assistance under No.F.510/12/DRS-II/2018(SAP-I).Publisher's Versio

k-trees, k-ctrees and Line Splitting Graphs

Let G = (V,E) be a graph. For each edge ei of G, a new vertexe?i is taken and the resulting set of vertices is denoted by E1(G). Theline splitting graph Ls(G) of a graph G is defined as the graph havingvertex set E(G)SE1(G) with two vertices adjacent if they correspondto adjacent edges of G or one corresponds to an element e?i of E1(G)and the other to an element ej of E(G) where ej is in N(ei). In thispaper we characterize graphs whose line splitting graphs are k ? treesand k ? ctrees

Hub-integrity of splitting graph and duplication of graph elements

The hub-integrity of a graph G = (V (G), E(G)) is denoted as HI(G) and defined by HI(G) = min{|S| + m(G − S), S is a hub set of G}, where m(G − S) is the order of a maximum component of G − S. In this paper, we discuss hub-integrity of splitting graph and duplication of an edge by vertex and duplication of vertex by an edge of some graphs.Publisher's Versio

Bharath hub number of graphs

The mathematical model of a real world problem is designed as Bharath hub number of graphs. In this paper, we study the graph theoretic properties of this variant. Also, we give results for Bharath hub number of join and corona of two connected graphs, cartesian product and lexicographic product of some standard graphs.Publisher's Versio

Domination Integrity of Line Splitting Graph and Central Graph of Path, Cycle and Star Graphs

The domination integrity of a connected graph G = (V (G);E(G)) is denoted as DI(G) and defined by DI(G) = min{|S| + m(G - S)}, where S is a dominating set and m(G-S) is the order of a maximum component of G-S. This paper discusses domination integrity of line splitting graph and central graph of some graphs

The Eccentric-distance Sum of Some Graphs

Let $G = (V,E)$ be a simple connected graph. Theeccentric-distance sum of $G$ is defined as\xi^{ds}(G) =\ds\sum_{\{u,v\}\subseteq V(G)} [e(u)+e(v)] d(u,v), where $e(u)$ %\dsis the eccentricity of the vertex $u$ in $G$ and $d(u,v)$ is thedistance between $u$ and $v$. In this paper, we establish formulaeto calculate the eccentric-distance sum for some graphs, namelywheel, star, broom, lollipop, double star, friendship, multi-stargraph and the join of $P_{n-2}$ and $P_2$

Synthesis and Structural Characterization of Nanomanganese Ferrites

In this paper, the structural properties of nano manganese ferrite are synthesized by using environmental friendly co-precipitation method is reported. The structural parameters such as the lattice constant, average crystallite size (D), texture coefficients (TC), lattice strain (ε) and dislocation density (ρ) have been determined using X-ray diffraction data

Studies in the Amenability of Kolhapur Bauxite to Bayer's Process-Parts I and 11

DETERMINATION of the digestibility pattern of the bauxite samples is the most important step towards the design of an integrated alumina plant principally based on Bayer's process. Of all the aluminous minerals, the trihydrate gibbsite is the most amenable to Caustic digestion, and diaspore the hardest to treat. Altekar and Mathadt proceeded to determine the mineralogical set-up of the Kolhapur bauxite. The samples were obtained by the senior author from seventeen different pits dug to an average depth of 17' in a 30-acre plateau on top of a 3,000' high hill near Udgcri. The deposit has been since estimated at 3'5 million tons of bauxite. The findings of the author were that the principal and predominant mineral of alum-inium is gibbsite and it was therefore predicted that its response to caustic treatment would be quite favourable. Thic paper records the results of detailed investigations concerning the digestion of the bauxit
