The effect of the glass industry on heavy metal characterization was assessed in the sludge/sediments of 5 discharge pits (sites) for effluents of functional glass factories and/or finishing workshops in the study area. A comprehensive profile of Zn, Mn, Co, Cd, Pb, Cr, Ni,Cu and As levels in industrial sludge was obtained. Correlation coefficients for metal pairs indicate varying levels (posit...

During the last years our research group has been studying the use of industrial vegetable wastes as grape stalks and exhausted coffee to remove metals ions such as Ni(II), Cu(II), Pb(II), Zn(II), Cd(II) or Cr(VI) and Cr(III) in aqueous solution from the point of view to use these wastes as biosorbents in a low cost alternative to activated carbon for wastewater treatment. The optimal experimen...

Magneto rheological fluid (MRF) is a smart fluid whose properties can be controlled with the help of metal particles and magnetic field. These fluids have the ability to transmit force in a controlled manner with the help of magnetic field, thus improving their performance especially in areas where controlled fluid motion is required. Some applications of magneto rheological fluid technology ar...

The marginal fit is one of the most important criteria for long-term success of all-ceramic restorations.[1] When considered clinically, a casting becomes acceptable only when the marginal gap between the prepared tooth and the casting is indiscernible both visually and also while probing. The marginal gap may lead to increased retention of plaque. This changes the distribution of microflora as...

The "RapidTool" Short Run (SR) Tooling Process using the Copper Polyamide material provides a route to mold inserts for injection molding made directly in the Selective Laser Sintering machine. The STL files for the mold inserts are shelled and conformal cooling lines and ejector pin guides are added before SLS processing. Sintering of the material in the SLS machine provides quick metal/plasti...

The information contained in this publication has been compiled from the literature and through communication with recognized experts within the metal finishing industry. It is presented as a guide to the use of electroless nickel for engineers, metallurgists, designers and others involved in materials selection. The important properties of electroless nickel deposits are described and examples...

Control of hot metal rolling process plays an important role in assuring high product quality and safe process operation. Although there have been many looper control technologies recently developed for finishing rolling processes, looperless interstand tension control of roughing and intermediate rolling mills remains a hard-to-solve problem. This paper proposes a current comparison based inte...
