present work ‚ in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to synthesize polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites‚thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer and X-ray diffraction . The morphology of these composites was studied by scanning electron microscopy. (Received September 29‚ 2009; accepted October 23‚ 2009) Keywords: Conductivity ‚ polyaniline ‚poly(p-hydroxyaniline)

Code Division Multiple Access INTRODUCTION:- Mobile communications are rapidly becoming more and more necessary for everyday activities. With so many more users to accommodate‚ more efficient use of bandwidth is a priority among cellular phone system operators. Equally important is the security and reliability of these calls. One solution that has been offered is a CODE DIVISION MULTIPLE ACCESS SYSTEM. CDMA is one method for implementing a multiple access communication

parts of the text slightly terse and might want a more elaborate book. The following list of books might be helpful: 1. Time Series Analysis with Applications in R by Cryer and Chan. This book has plenty of data analysis examples using R. 2. Fourier Analysis of Time Series by Bloomfield. This book only covers the frequency domain approach. 3.

Johann Sebastian Bach was one of the greatest composers in history. “People felt his music and art helped protect people against the advance of doubt bred by the renaissance ideas of scientific‚ rational inquiry.”(The World Book Encyclopedia 2012. Chicago‚ IL: World Book‚ 2012. Print). He bought music techniques such as Counterpoint (playing of two or more melodies at one time) and Fugue(where different instruments repeat the same melody with slight variation) to their greatest heights. He wrote

to Who is. . . in “Self-Reliance”? Here is a guide to Emerson’s many allusions and references. You don’t need to study these--just use them as reference if you are confused. John Adams Emerson refers to ‘‘great days and victories behind’’ that ‘‘shed a united light‚’’ which in turn ‘‘throws ...

Chapter #9 Summary: New Directions in Planning Theory Susan S. Fainstein Susan S. is professor of urban planning and acting program director in Columbia University. In this article she discusses and critiques contemporary planning theory in terms of its usefulness in addressing what I believe to be its defining question: what is the possibility of consciously achieving widespread improvement in the quality of human life within the context of a global capitalist political economy. She examines
