Various surfactant modified silica layers were used for the chromatography of five different Cephalosporins. The 4% methanolic CTAB impregnated silica layer was useful for the chromatography of Cephalosporins. The acidic buffer solvent systems were used with the 4% methanolic CTAB impregnated silica layers for the separation of different mixtures [A (Cefaclor, Ceftriaxone and Cefadroxil), B (Ce...

The residual concentration and efficacy of Abate 5CG (impregnated in celatom granules) and plaster pellets impregnated with either Abate 4E or technical temephos were compared against late 3rd-instar Aedes aegypti larvae. Both plaster pellet formulations resulted in 100% larval mortality during the 6-wk test, compared with 2 wk for a similar level of mortality for the celatom formulation. The m...

As a part of the Fermilab high field Nb3Sn dipole development program, various issues of magnet technology are being investigated. In cable insulation development, S-2 fiber glass sleeve and a new ceramic insulation developed by Composite Technology Development Inc. (CTD) were studied as a possible candidates. For each type of insulation, Nb3Sn ten-stack samples were reacted and then vacuum imp...

A 34-year-old man presented to the hospital with right-sided headache. He was diagnosed with GBM. He underwent resection of the tumor with placement of carmustine impregnated wafers. Then he underwent adjuvant chemotherapy with temozolamide. Before the completion of chemotherapy he had a recurrence. He underwent re-resection with placement of carmustine impregnated wafers. Subsequently he had e...

We studied different face velocity and carbon dioxide (CO2) initial concentration to examine the adsorption behavior of calcium oxide (CaO) impregnated activated carbon (AC) filter and also to discuss pseudo-first-order, pseudo-second-order and intra-particle diffusion three kinetic models. The experimental results show that saturation time and saturation capacity were decreased and increased w...

Lubricant-impregnated surfaces (LIS), where micro/nanotextured surfaces are impregnated with lubricating liquids, have received significant attention for their robust, superslippery properties. In this study, we systematically demonstrate the potential for LIS to reduce drag in laminar flows. We present a scaling model that incorporates the viscosity of the lubricant and elucidates the dependen...

Fluoridated mouthrinses are not advised for preschool children who may swallow much of the agent. An alternate method of delivering topical fluoride to the interproximal tooth surfaces in these young patients may be fluoridated dental floss. The purpose of this study was to determine the fluoride levels of demineralized primary enamel both before and after the use of a commercially available de...

We have studied 35 patients with infected reconstructions after segmental resection for bone tumours. Two different regimes of treatment were employed both of which entailed debridement and the use of cement impregnated with antibiotic. In 25 patients gentamicin-PMMA beads were used and in ten an antibiotic-impregnated cement spacer. Better results were achieved with the second procedure in ter...

We propose an alternative new material (2,4,5-trifluoroimidazole impregnated Nafion) for use as a high-temperature, water-free membrane for proton-exchange membrane fuel cells. This material has been tested computationally using molecular dynamics and quantum mechanics techniques, leading to an estimated conductivity of approximately 0.06 S/cm at 177 degrees C. This material overcomes the weakn...

In this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. Fabrics are impregnated with Shear Thickening Fluid (STF). The effects of the (STF) have been considered as frictional effect. The STF has been made (Nano Silica and Polyethylene Glycol (PEG)) and then diluted by ethanol proportion of 3:1. Yarn pulling out test from in...
