Bit Error Rate (BER) and Bit Energy to Noise Ratio performance of the 1-D RAKE receiver without , with Space Time Transmit Diversity (STTD) and 2-D RAKE without , with (STTD) and also without and with beamforming for WCDMA over Rayleigh Channel in presence of Additive White Gaussian Noise (AWGN) channel is demonstrated with purpose of making simulation of m-files developed in Matlab.Results are evaluated in terms of BER and  considering the number of Base Station (BS) transmit antennas (1-D RAKE and 2-D RAKE receivers), and the number of RAKE fingers (1-D RAKE r

This study aimed to modify Staphylococcus aureus by using physical and chemical mutagens and subjections the cell wall to the hydrolytic activity of lysozyme. Chemical mutagenesis by N-methyle-N-nitro-N-nitroguanidine, was achieved by incubating the cell suspension of Staphylococcus aureus with 100μg/ml MNNG for different periods of time (5, 10, 15, 20, 25 and 30min).Aliquot of 100μl of the bacterial suspension subjected to the lethal and mutagenic effect of MNNG, then spread on BHI agar and incubated at 37°C over night in dark.

This thesis presents the design and implementation of a private cloud computing system using a combination of two HP servers with specifications of Intel Xeon 8 core processor, 16GB RAM, 500 GB Hard Disk and two NICs as a physical resources and VMware ESXi as a virtualization software. Most of Iraqi hospitals do not offer e-services and there is a need to digitalize the request, report, store, and retrieve the medical data in these hospitals as well as provides other e-services such as e-mail and VoIP services.

Bone acrylic cement is widely used as a structural material in orthopaedics, dentistry, and orofacial surgery. Although bone cement celebrates four decades of success, it remains susceptible to fatigue fracture. This type of failure can directly lead to implant loosening, revision surgery, and increased healthcare expenditures. In this thesis, the application of mixing and vacuum technique to fabricate bone cement enhance its strength and fatigue performance.
