This paper describes a proposal for FAT tree based Network-on- Chip system based on MPLS forwarding mechanism. The FAT tree includes processing nodes and communication switches. IP node (processing nodes) has a message generator unit which randomly generates messages to different destinations with different packet lengths and buffering. The switch is based on MPLS technique and consists of the following units: crossbar switch, input/output link controllers and routing and arbitration units. A simulator has been developed in C++ to analyze the proposed architecture. A comparison with wormhole switch is provided to show the efficiency of the MPLS designed switch arabic 12 English 65

This paper describes a Fat tree based Network-on- Chip system using MPLS networking technique. A discrete-event simulator has been developed in C++ in in order to demonstrate the applicability of the MPLS to Network-on-Chip systems. The correctness and the efficiency of the MPLS based Fat networkon- chip system is measured against well-known wormhole with virtual channels technique. The results of the MPLS-based NoC in terms of throughput and latency are clearly proves the applicability of the MPLS to implement future NoC designs arabic 8 English 38

The use of the communication and information technology tools can aid students in their lab work to add more flexibility to the accessibility and providing of up-to-date higher education allowing students accessing knowledge anytime, anywhere which will facilitate the lifelong learning and provide accessibility to the curriculum and other students’ resources from anywhere at any time. Laboratory work by students in the information technology and engineering fields of study is a must requirement in all accreditation agencies and targeted employment places. This chapter demonstrates a project based learning technique that has been integrated with ordinary classes in computer network courses. The tools used in this study concentrates on the modeling and simulation of different aspect of computer networking that highlight different skills needed to any computer network engineer. arabic 8 English 53

This paper is presenting a discrete-event simulator written in C++ for modeling and simulating Fat tree network-on-chip systems based on MPLS technique. The simulator contains main component that construct butterfly Fat tree structure and other components that generate suitable number of switches and IP nodes (cores). The designed switch consists of input ports, output ports, input/output link controller, multi-buffers, crossbar switch, routing and arbitration components and MPLS unit. The correctness and the efficiency of the MPLS based Fat network-on-chip system is measured against well-known wormhole+ virtual channels technique. The produced results are clearly demonstrated the efficiency of the MPLS technique for future NoC designs. arabic 45 English 189

The object of the present study was to assess the possible alterations in blood of sheep that may occur following intramuscular injection of tobramycin. Tobramycin was injected to 10 sheep at a dosage regimen of 5 mg/kg of body weight for 5 successive days. Two types of blood samples (with and without EDTA as an anticoagulant) were collected from the jugular vein before and after the antibiotic course. Tobramycin significantly (p arabic 13 English 83

The present study aimed at evaluation of the immuomodulatory effect of sulphadimidine by investigating its ability to affect constitutive expression of MHC-II molecules on B-cells, which are one determinant of antigen presentation and the vigor of immunity. Three groups of broiler chicken were used, the first two groups received 100 mg/kg and 200 mg/kg sulfadimidine, respectively, in drinking water; while the third group was left as control. Bursal samples were taken after 7 and 14 days of treatment and checked for MHC-II gene expression by RT-PCR technique. The obtained results demonstrate that oral administration of sulphadimidine inhibited the expression of MHC-II mRNA in bursal of Fabricius of broiler chicken in a dose and age dependent manner. This finding is of clinical importance as many farmers routinely add sulpha drugs to drinking water as a prophylactic measure against some infections; yet the data presented in this study doesn't recommend this managing behavior. arabic 11 English 83

The relationship between ATP-induced membrane potential and contraction was inestigated in the smooth muscle of chicken anterior mesenteric artery using micro-electrode and tension recording techniques respectively. Application of ATP to en-dothelium-denuded arterial preparations developed concentration-dependent, slow depolarization which started only at concentrations not less than 10 μM. On the other hand the tension recording experiment revealed that ATP produced concentration dependent contractions, which were evident at concentrations lower than those evoked depolarizing response to ATP (as lower 100 nM). Both depolarizing & contracting responses were abolished by the P2X receptor blocker, PPADS (50 μM) but not by P2Y receptor blocker CBF3GA (100 μM), indicating that the excitatory responses of ATP were mediated via activation of P2X receptor. These findings suggest that ATP-mediated contraction is not dependent on membrane depolarization only, at least at low concentrations in the first order branches of chicken anterior mesenteric artery. arabic 21 English 153

he present prospective study was designed to conduct a local survey on patients under anti-tuberculosis therapy hospitalized in Abo-Seta hospital, Tripoli, Libya from the safety point of view. The study was carried out on 75 inpatients. The effects of the used drugs on some hematological parameters and liver function biomarkers were monitored for six-month period of treatment. Our survey showed that tuberculosis affects people with low and medium levels of education and with no job. The frequency of adverse effects related to treatment with Abo-Seta hospital regimen were decreases in WBCs count (-38.7%), RBCs count (-32.1%), platelets count (-33%) and hemoglobin concentration (-35.5%). However, in most of the cases, it was not necessary to modify the treatment regimen because of such side effects. Some parameters showed spontaneous recovery as RBCs count (+22.1%) and hemoglobin level (+20.1%). Combined therapy of ethambutol, isoniazid, pyrazinamide, and rifampicin has been used in Abo-Seta hospital, as a regimen for tuberculosis infection, may be associated with a high risk of hepatic toxicity during first month of treatment. However, during the remaining five months there was a good recovery of liver enzymes profile. Upon the data obtained from the present study, it could be concluded that TB patient after 6 month of treatment didn't develop multi-drug resistant tuberculosis (MDR-TB arabic 13 English 83
