We present results of molecular dynamics simulations of strong, exible polyelectrolyte chains in solution with added salt. The eeect of added salt on the polyelectrolyte chain structure is fully treated for the rst time as a function of polymer density. Systems above and below the Manning condensation limit are studied. The chain structure is intimately tied to the ion density near the chain ev...

Porous PEEK structures with approximately 85% open porosity have been made using PEEKOPTIMA® powder and a particulate leaching technique using porous, near-spherical, sodium chloride beads. A novel manufacturing approach is presented and compared with a traditional dry mixing method. Irrespective of the method used, the use of near-spherical beads with a fairly narrow size range results in unif...

Thermal power stations using pulverised coal as fuel, generate large quantity of ash as waste by product, which poses dual problem of environment and disposal. Flyash is a versatile material with many possible applications such as land filling and in land reclamation of low lying areas. An experimental investigation has been carried out to study the behaviour of compacted ash overlying sand dep...

RESEARCH QUESTION What is the current status of Iodine Deficiency Disorders (IDD) in the state of Jharkhand? OBJECTIVES (1) To determine the status of iodine deficiency in the state. (2) To determine the availability and cost of adequately iodized salt at the retail shops. (3) To study the perceptions of the community regarding iodine deficiency, salt and iodized salt. DESIGN A cross-sectio...

In this work an attempt has been made to estimate the pollution flashover voltage under various meteorological factors using radial basis function (RBF) neural networks. Orthogonal least squares (OLS) learning method is used in order to improve the lines performance against the pollution flashover of the post insulators. The technique of RBF neural network is employed to model the relationship ...

MRI is finding increased clinical use in neonatal populations; the extent to which electromagnetic models used for quantification of specific absorption rate (SAR) by commercial MRI scanners accurately reflect this alternative scenario is unclear. This study investigates how SAR predictions relating to adults can be related to neonates under differing conditions when imaged using 1.5 T and 3 T ...
