This paper addresses the problem of incorporating topological indices as structural descriptors for correlating properties in the design of product molecules with fine-tuned or optimized property values. Three different types of topological indices are considered: Randir's molecular connectivity indices, Kier's shape indices and the Wiener Index. The adjacency matrix representation which provid...

2014The positional order correlation length « 03BE~ » parallel to the smectic (Sm) layers in the G, F and C phases of HBHA (7O.6) has been measured by X-ray diffraction. In the Sm-G phase its value is limited by crystallite size and lies between 1200-1500 A. At the Sm-G to -F transition 03BE ~ changes from 300 to 180 A with a temperature dependence predicted by a dislocation mediated melting mo...

During the last two decades a large number of numerical graph invariants (topological indices) have been defined and used for correlation analysis in theoretical chemisty, pharmacology, toxicology, and environmental chemistry. However, no systematic study has been undertaken to determine to what extent these indices are correlated with each other. In the present paper we have carried out a prin...

OBJECTIVE To improve the prediction of fractures in dogs with bone tumors of the distal radius by identifying computed tomography (CT) indices that correlate with antebrachial bone strength and fracture location. STUDY DESIGN Prospective experimental study. ANIMALS Dogs with antebrachial osteosarcoma (n = 10), and normal cadaver bones (n=9). METHODS Antebrachia were imaged with quantitati...

PRIMARY OBJECTIVE To determine if individuals with brain injury can modify heart rate variability (HRV) through biofeedback and, if so, enhance its pattern to improve emotional regulation and problem-solving ability. DESIGN A quasi-experimental design with repeated measures was employed. Thirteen individuals aged 23-63 years with severe brain injury (13-40 years post-onset) participating in a...

OBJECTIVES Manganese exposure leads to diffuse cerebral metal deposition with the highest concentration in the globus pallidus associated with increased T1-weighted MRI signal. T1 signal intensity in extra-pallidal basal ganglia (caudate and putamen) has not been studied in occupationally exposed workers. Diffusion weighted imaging is a non-invasive measure of neuronal damage and may provide a ...

OBJECTIVES To examine the relations between maximal and submaximal indices of aerobic fitness and off road cycling performance in a homogeneous group of high level mountain bikers. METHODS 12 internationally competitive mountain bikers completed the study. Maximum oxygen uptake (Vo(2max)), peak power output (PPO), power output (PO), and oxygen uptake (Vo(2)) at first (VT) and second (RCT) ven...
