Let G and H be two graphs. The corona product G o H is obtained by taking one copy of G and |V(G)| copies of H; and by joining each vertex of the i-th copy of H to the i-th vertex of G, i = 1, 2, …, |V(G)|. In this paper, we compute PI and hyper–Wiener indices of the corona product of graphs.

OBJECTIVE To evaluate ultrasonographic methods, including the Doppler technique, as measures of synovial inflammation in finger joints of patients with rheumatoid arthritis. METHODS Ultrasonography was performed with a high frequency transducer (13 MHz). Evaluation of the sonographic data was conducted by two independent observers and included measurement of synovial area and thickness (grey ...

STUDY OBJECTIVES Determine the relationship of non-rapid eye movement (NREM) electroencephalographic (EEG) spectral measures and the response to cognitive behavioral therapy (CBT) in primary insomnia (PI). DESIGN Patients with PI were randomly assigned to CBT or a placebo intervention (PC). Ambulatory polysomnography was performed before and after treatment. SETTING University medical cente...

The sequence of all paths pi of lengths i = 1 to the maximum possible length in a hydrogen-depleted molecular graph (which sequence is also called the molecular path code) contains significant information on the molecular topology, and as such it is a reasonable choice to be selected as the basis of topological indices (TIs). Four new (or five partly new) TIs with progressively improved perform...

The concentrations of Cu, Zn, As, Pb, Cr, and Cd in soil were analyzed a mining area the Inner Mongolia Autonomous Region, China. average metal samples 204.07 mg/kg, 88.15 14.47 mg/kg 88.52 56.45 0.235 respectively. Based on evaluation standards, background values heavy metals, multiple pollution assessment indices, such as single factor index (Pi), geological accumulation (Igeo), Nemerow (Pn),...

OBJECTIVES The aim of this pilot study was to evaluate the periodontal effects during rapid palatal expansion (RPE) or slow palatal expansion (SPE) and to compare them by means of some clinical indices, in order to establish the possible differences and advantages of one of these treatments in periodontal terms. METHODS 10 patients (aged 6 to 7 years; average age 6.3 years) were submitted to ...

OBJECTIVE Renal Doppler Ultrasound (RDU) indices: resistive index (RI) and pulsatility index (PI) are frequently applied as a noninvasive method that measured possible causes of allograft dysfunction in kidney transplant patients. We aimed to compare long-term prognosis and associated risk factors including the RDU markers in recipients with and without new-onset diabetes after transplantation ...

the electric quadrupole, hexadecapole moments, energy (kjmol -1) for some armchair polyhex carbon nanotubes tuvc6[2p,q] are performed by beck-lee-yang-parr [b3lyp] on 3-21g basis set using the standard procedure indices gaussian 98, then the padmakar-ivan (pi) index of tuvc6[2p,q] nanotubes in the terms of their circumference (2p) and lengh (q) is calculated and the relationships between the pa...

background: there is a fundamental correlation between follicles and endometrium in intracytoplasmic sperm injection (icsi) cycles. objective: to assess the relation between perifollicular perfusion and sub endometrial parameters in doppler ultrasonography and outcome of in icsi cycles. materials and methods: in this prospective deh1ive pilot study 10 patients were enrolled. strict inclusion cr...
