abstract. topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. graph theory is a delightful playground for the exploration of proof techniques in discrete mathematics and its results have applications in many areas of sciences. a graph is a ...

The Wiener index of a graph G is defined as W(G) = 1/2∑{x,y}⊆V(G)d(x,y), where V(G) is the set of all vertices of G and for x,y ∈ V(G), d(x,y) denotes the length of a minimal path between x and y. In this paper, we first report our recent results on computing Wiener, PI and Balaban indices of some nanotubes and nanotori. Next, the PI and Szeged indices of a new type of nanostar dendrimers are c...

In the present investigation the applicability of various topological indices are tested for the QSPR study on 80 amino acids derivatives. Relationship between the Randic' (1X), Balaban (J), Szeged (Sz), Harary (H), Wiener (W), Hyper-Wiener (WW) and Wiener Polarity (WP) indices to the thermodynamic Properties such as thermal energy Eth (J/mol) and heat capacity (CV J/mol. K) of amino acids is r...

qspr study on benzene derivatives have been made using recently introduced topological methodology. in this study the relationship between the randic' (x'), balaban (j), szeged (sz),harary (h), wiener (w), hyperwiener and wiener polarity (wp) to the thermal energy (eth), heat capacity (cv) and entropy (s) of benzene derivatives is represented.physicochemical properties are taken from the quantu...

The current study examines the modality preference and its change in the course of development. Based on findings from previous research (Balaban & Waxman, 1997; Roberts, 1995; Sloutsky & Lo, 1999), it was expected that the auditory modality would be privileged at a very young age. In the experiment, participants after being trained to select a target image and sound combination were required t...

The toxicity data of 42 nitroaromatic compounds related to 50% growth inhibitory concentration (log IGC50) were used to develop Quantitative structure toxicity relationship to tetrahymena pyriformis.The multiple linear regression method was applied to select the descriptors.The six parametric model were found to be the best which gives a variance of more than 92% (R2=0.9248). Our results have s...
