topological indices are numerical parameters of a graph which characterize its topology. inthis paper the pi, szeged and zagreb group indices of the tetrameric 1,3–adamantane arecomputed.

in theoretical chemistry, molecular structure descriptors are used to compute properties of chemical compounds. among them wiener, szeged and detour indices play significant roles in anticipating chemical phenomena. in the present paper, we study these topological indices with respect to their difference number.

The main objective of this research is to establish a connection between orthodontic mini-implant design, pull-out force and primary stability by comparing two commercial mini-implants or temporary anchorage devices, Tomas®-pin Perfect Anchor. Mini-implant geometric analysis quantification bone characteristics are performed, whereupon experimental in vitro test conducted. With the use CATIA (Co...

likely that the increases in waist circumference are genuine. Increases in waist circumference on current and future morbidity should be a cause for concern. One US study found that young people above the 90th cen-tile for waist circumference had higher concentrations of low density lipoprotein cholesterol, triglycerides, and insulin and lower concentrations of high density lipoprotein choleste...
