THE Eastman Kodak multiple-stylus electronic printer prints, at high speed, outputs from electronic computers, insurance premium notices, utility bills, addresses on magazine labels, addresses on cards and envelopes, and so forth. High-speed printed communication is also a field for this printer, as it can be operated by remote control, without synchronization. This nonphotographic electromecha...

in this work, we report synthesis of silver nanoplates by a simple reduction process of silver nitrate in the presence of polyvinyl alcohol (pva) and n,n'-dimethyl formamide (dmf). the characterization of the samples were carried out using x-ray diffraction (xrd), transmission-electron microscopy (tem) and uv-vis spectroscopy. absorption spectra of the nanoplates in comparison with that of...

Free vibration and wave analysis of thick rectangular graphene are studied by employing the propagation method. To consider small-scale effects thickness a plate in nanoscales, equations motions represented Eringen nonlocal theory coupled with Mindlin plates. solve governing motion technique, reflection matrices derived. These combined to obtain exact natural frequencies sheets for all six poss...

This reaffirmation of teachers has been a leading factor in the development of recent strategies for school improvement The reports by the Carnegie Task Force and the Holmes Group are two prominent examples of proposals aimed specifically at problems within the teaching profession. These reports are significant in that they have helped place teaching squarely at the center of current educationa...

Abstract : Microstrip antennas or patch antennas are popular for their attractive features such as low profile, low weight, low cost, ease of fabrication and integration with RF devices. Micro strip antennas have been found favorable because they are inexpensive to manufacture and compatible with monolithic microwave integrated circuit designs (MMIC). They are usually employed at UHF and higher...
