Mobile ad hoc network is nothing but the temporary network which is having the collection of mobile nodes. Routing and broadcasting are major operations of MANET network. The major operation in ad hoc mobile network is the broadcasting which sometime results to storm problem of the broadcast if the forwarding mechanism is not properly designated. Thus the challenges in the MANET are to reduce the broadcasting redundancy and under high transmission error rate provides high delivery ratio. Hence in our proposed research, we are introducing and investigating the new mechanism of broadcasting called Dual Covered Broadcast. This method takes the broadcast redundancy advantage order to improve packet delivery ratio especially under environments where transmission error rate higher. According to proposed approach, among the senders 1-hop neighbors, forwarding nodes which are selected are only retransmit the broadcasting message. There are two ways for selection of forwarding nodes and either of one is used depending on the network conditions. The source node provides forwarding node retransmission as acknowledgement of reception of packet. If the source node not getting the retransmissions of its forwarding nodes, source node resend the packets until the maximum threshold will reach. For the simulation of this project we used the Microsoft .Net framework and our simulation results shows that proposed method performing well under the high transmission error rate. From the simulated results we claim that investigated approach for the broadcasting is more efficient as compared to the existing approaches.

The differences in the expression of this gene between patients and healthy controls were studied. The correlation of gender and age with CML patients compared with controls was included as well as the correlation of gene expression folding 2-ΔΔCt of LTB4R with clinical parameters (WBC, RBC, haemoglobin, platelets, and BCR-ABL gene). Results revealed significant increases in the mean of gene expression level (ΔCt) of patient groups compared to the corresponding ΔCt means in the healthy control group, the gene expression folding (2-∆∆Ct) of the L

selected downstream the channel during dry season. The examined water parameters were pH, NH3, NO3, PO= 4, BOD5, COD, TDS, S.S, Cl-, SO= 4, Na+ , Ca+2, Mg+2, and Oil and Grease. Descriptive and inferential methods through finding the best curve fit correlation were employed in the study to test the strength of the association between water chemical characteristics and distance downstream the channel.

This study analyzes the features of historical and modern mosques in Jordan compared to that of Amman. The architecture of the Jordanian mosques reflects the images of great ancient empires and kingdoms of Europe and the Middle East. This has happened due to the geographical position of the country. From the studies of historians and archaeologists, comparative analysis of planning solutions, the use of plastics and decor of the facades of mosques, and the literature on the construction methods of the mosques allow us to conclude that age-old traditions have been preserved through the establishment of mosques in both the countries. Besides, the emergence of new features in constructing mosques has been observed. We find the influence of

Because the diversity of disease processes and formation of complex lymphoid microstructures that indicate the multiple T cell activation pathways are involved .affected patients have major abnormalities in the T cell pool with clonally expanded CD4 + T cell that lose expression of the CD28null molecule and lack the ability for profiliration. Adenosine deaminase (ADA) is an indicator of the proliferation and differenation of lymphocyte, in particularly the T cell subcells.
Patients and Methods: Total ADA levels were measured in the sera of RA patients and healthy group according to Giusti (1981).
Results: The mean value of ADA was lo
