Topological indices are numerical parameters of a graph which characterize its topology. In this paper the PI, Szeged and Zagreb group indices of the tetrameric 1,3–adamantane are computed.
Background and purpose: Osteoporosis and periodontitis are two diseases associated with bone loss and are common among postmenopausal women. There are many contradictory results on the effect of osteoporosis on periodontal tissue. This study aimed to determine the association between osteoporosis and periodontal status in postmenopausal women. Materials and methods: This cross-sectional study...
This research was conducted to evaluate drought tolerance of safflower genotypes (Carthamus tinctorius L.) at the research farm of Isfahan University of Technology, Isfahan, Iran during growing season of 2012. One hundred genotypes including 81 foreign genotypes along with 19 Iranian genotypes were evaluated under normal and moisture stress conditions according to a simple lattice design with t...
INTRODUCTION We examined the best-fit index for describing the constitutional or physical characteristics of Sasang typology for its universal application. METHODS Ponderal index (PI), body mass index (BMI), and basal metabolic rate (BMR) of the nationwide participants (n = 1663; age, 31-60 years) were calculated. We described and analyzed the usefulness of each index for maximizing the diffe...
Resistance to Meloidogyne arenaria race 1 is not currently available in commercial peanut cultivars. Moderate levels of resistance have been identified in Arachis hypogaea plant introductions (PI) in previous greenhouse studies. The purpose of this work was to evaluate the effects of resistance in peanut PI on populations dynamics of M. arenaria in field plots. The PI designated as resistant in...
In patients with HUS-N, TCD showed only slightly increased blood flow velocities of basal brain arteries ( table 1 ). However, the mean resistance index (RI) and in particular the mean pulsatility index (PI) were significantly increased in patients with HUS-N, compared to HUS patients without neurological symptoms (mean PI/RI 1.11/0.62 vs. PI/RI 0.72/0.48, p ! 0.001, Mann Whitney U test; table ...
In this paper the Wiener and hyper Wiener index of two kinds of dendrimer graphs are determined. Using the Wiener index formula, the Szeged, Schultz, PI and Gutman indices of these graphs are also determined.
