Relation between Healthy Eating Index and Resting Metabolic Rate
Background and Objectives: Previouse studies demonstrated inverse association between healthy eating index and alot of chronic diseases like cardiovascular disease and cancer and mortality. Since there are limited study about relation between healthy eating index and reting metabolic rate. considering the results of some studies about the relation between weight, body composition and blood suge...
متن کاملOn relation between the Kirchhoff index and number of spanning trees of graph
Let $G=(V,E)$, $V={1,2,ldots,n}$, $E={e_1,e_2,ldots,e_m}$,be a simple connected graph, with sequence of vertex degrees$Delta =d_1geq d_2geqcdotsgeq d_n=delta >0$ and Laplacian eigenvalues$mu_1geq mu_2geqcdotsgeqmu_{n-1}>mu_n=0$. Denote by $Kf(G)=nsum_{i=1}^{n-1}frac{1}{mu_i}$ and $t=t(G)=frac 1n prod_{i=1}^{n-1} mu_i$ the Kirchhoff index and number of spanning tree...
متن کاملRelation between Randić Index and Average Distance of Trees
The Randić index R(G) of a graph G is the sum of weights (deg(u) deg(v))−0.5 over all edges uv of G, where deg(v) denotes the degree of a vertex v. We prove that for any tree T with n1 leaves R(T ) ≥ ad(T ) + max(0,n1 − 2), where ad(T ) is the average distance between vertices of T . As a consequence we resolve the conjecture R(G) ≥ ad(G) given by Fajtlowicz in 1988 for the case when G is a tree.
متن کاملOn a Relation Between Randić Index and Algebraic Connectivity
A conjecture of AutoGraphiX on the relation between the Randić index R and the algebraic connectivity a of a connected graph G is: R a ≤ ( n− 3 + 2√2 2 ) / ( 2(1− cos π n ) ) with equality if and only if G is Pn, which was proposed by Aouchiche et al. [M. Aouchiche, P. Hansen and M. Zheng, Variable neighborhood search for extremal graphs 19: further conjectures and results about the Randić inde...
متن کاملOn Relation between the Kirchhoff Index and Laplacian-Energy-Like Invariant of Graphs
Let G be a simple connected graph with n ≤ 2 vertices and m edges, and let μ1 ≥ μ2 ≥...≥μn-1 >μn=0 be its Laplacian eigenvalues. The Kirchhoff index and Laplacian-energy-like invariant (LEL) of graph G are defined as Kf(G)=nΣi=1n-1<...
