the present study was carried out to investigate the potential of carboxylate group functionalized multi-walled carbon nanotubes (mwcnt−cooh) adsorbent for the removal of methyl orange (mo) textile dye from aqueous solutions. the effects of ph, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚k was fixed at 25 min. the effect of te...

A parametric study of twenty-five reinforced concrete ring deep beams using finite element analysis is presented in this study. This paper took into account the kind loading (partial and complete), diameter, depth, width beam, as well NO. supports. When compared to equivalent concentrated central loading, acting a partial distributed 25-100 percent length span increased capacity load by about 3...

41 patients with trauma to the urinary bladder are reviewed. 70 percent were injured as a result of blunt trauma and 63 percent of patients had an associated fracture of the pelvis. 82 percent of extra peritoneal ruptures were associated with fracture of the pelvis. The most common cause of trauma was car accident (56 percent), followed bywar injury (25 percent). The incidence of intra and...

At birth the newborn infant is required to make an abrupt adjustment to a new environment. Hitherto its existence has been parasitic and its needs have been supplied by the maternal organism. The most immediate dramatic changes required to support extra uterine life are concerned with respiration and the circulation. The infant must achieve a regular respiratory rhythm and be able to expand its...

Much of the existing conceptualization of fluid flow in karst aquifers is based on work in extensively cemented and recrystallized Paleozoic and Mesozoic carbonates. Within these aquifers, flow is often primarily through conduits (White 1969, 1977; Smart and Hobbs 1986; Ford and Williams 1989), although diffuse flow may occur through secondary porosity, such as fractures and joints (Shuster and...

I magine a society with perfect economic equality. Perhaps out of sheer coincidence, the supply and demand for different types of labor happen to produce an equilibrium in which everyone earns exactly the same income. As a result, no one worries about the gap between the rich and poor, and no one debates to what extent public policy should make income redistribution a priority. Because people e...

That tired Ten-Percent claim pops up all the time. Last year, national magazine ads for U.S. Satellite Broadcasting showed a drawing of a brain. Under it was the caption, "You only use 11 percent of its potential." Well, they're a little closer than the ten-percent figure, but still off by about 89 percent. In July 1998, ABC television ran promotional spots for "The Secret Lives of Men," one of...

An information retrieval performance measure that is interpreted as the percent of perfect performance (PPP) can be used to study the effects of the inclusion of specific document features or feature classes or techniques in an information retrieval system. Using this, one can measure the relative quality of a new ranking algorithm, the result of incorporating specific types of metadata or folk...
