صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...

We present the resonant two-photon ionization (R2PI) spectra as well as the UV–UV and IR–UV double resonance spectra for the cyclic dipeptide Phe-Ser. The R2PI spectrum shows five strong transitions in the region of 37 500–37 900 cm . By performing UV–UV double resonance spectroscopy, we distinguished 5 different conformers. For each of these conformers, the origin is the most intense transitio...

In the current century, nanotechnology has gained great interest due to its ability modify size of metals nanoscale, which dramatically changes physical, chemical, and biological characteristics relative their bulk counterparts. The approaches used create nanoparticles (NPs) are و chemical وbiological. shortcomings in physical synthesis approaches, such as generation toxic by-products, energy c...

Optical radiation extends between microwaves and X-rays of the electromagnetic radiation and includes ultraviolet (UV), visible light (VL) and infrared (IR) components. The dose of radiation that reaches the skin is influenced by the ozone layer, position of the Sun, latitude, altitude, cloud cover and ground reflections. The photobiological effects of UV, VL and IR bands depend on their wavele...

مداخل يعسوت رامعم ميمصت " ةجاحلا بسح ةددعتم طئاسو " ABSTRACT in this paper we develop a Vhdlbased scalable architecture of a multimedia on demand server model. Te three server subsystems are:the control subsystem, the communication subsystem and the storage subsystem are modeled. The communication subsystem is designed as an interconnection network with meshed-pipe structure and delivers packe...
