In the present study, pressure drop have been measured for narrow sized silica sand slurry and bimodal slurry consisting of narrow sized silica sand and fly ash as fine particles in different proportions keeping the overall efflux concentration same using a pilot plant test loop. The pressure drop has been measured over a length of 4.0 m in 50 mm NB diameter pipe line for fully developed flow. ...

The influence of molecular weight asymmetry across an interface on the transient behavior of the interfacial tension is investigated for two different polymer combinations, polybutadiene (PBD)/polydimethylsiloxane (PDMS) and polybutene (PB)/PDMS. This choice ensures a minor diffuse interface using the first combination and a very diffuse interface in the latter case. Measurements of the interfa...

BACKGROUND Image-guidance maximizes the therapeutic index of brain irradiation by decreasing setup uncertainty. As dose-volume data emerge defining the tolerance of critical normal structures responsible for neuroendocrine function and neurocognition, minimizing clinical target volume (CTV) to planning target volume (PTV) expansion of targets near these structures potentially lessens long-term ...

Composition and quantity per person of Municipal Solid Waste (MSW) were analyzed in six municipalities with different collection systems. Samples of residual waste were sorted, classified and weighed in 21 categories. Collection data of total waste flow, including sourcesorted recycling materials, in the same area was analyzed. Multivariate data analyses were applied. The main questions to be a...

here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. these structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). the broadest photonic band gap occurs at the filling ratio of r/a = 0.17. two linear defect w1 waveguides couple to the ring....
