Evaluation The Effect of Some Plant Active Compounds on Bacterial Plasmid

Aqueous and methanolic extracts of dried aerial parts of Hibiscus sabdariffa and Harpagophytum procumbens were tested for their antimicrobial and curing activity against two microorganisms Escherichia coli HB 101 and Pseudomonas aeruginosa RB19 Chemical investigation on these extracts showed that Hibiscus sabdariffa methanolic extracts contain flavonoids and water extract contain glycosides and Saponins while the Harpagophytum procumbens methanolic extracts contain flavonoids and water extract contain glycosides. .

MULTIPATH INTERFERENCE CANCELLATION INVESTIGATION IN WCDMA COMMUNICATION NETWORKS

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

Effect of physical and chemical mutagens on Staphylococcus aureus cell wall

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.

Analytical and Approximate Solutions for Volterra Integro-Differential Equations and It’s Applications

The main objective of this thesis is to study and solve the Volterra integral and integro-differential equation and some scientific models for real life problems.This objective may be divided into three sub objectives, as follows: The first one is to classify and study the subject of the integral equations and to supply the basic definitions related to the Volterra integral and integro-differential equations. In the second sub objective we used the " dafterdar-jafari method " to solve Volterra integral and integro-differential equations.

Deployment of a Hospital Management Information System over a Private Cloud

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.

Share Audio Cryptography Using DCT Transform

An Effective and secure protection of sensitive information is the primary concern in communication systems or network storage systems, it is important for any information process to ensure data is not being tampered. To achieve confidentiality and integrity of multimedia information, various Secret Sharing Schemes (SSS) have been developed.This thesis presents a (2,n) threshold Secret Sharing Scheme, which is one of the types of SSS and a special  kind of  (k, n) threshold scheme.

MECHANICAL PROPERTIES OF DISPERSED CERAMIC NANO PARTICLES IN POLYMER COMPOSITE FOR ORTHOPEDIC APPLICATIONS

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.

أعمال السيادة في القانون العراقي

مفهوم فكرة السيادة التي كانت سائدة حتى نهاية القرن التاسع عشر والتطور الذي حصل بعد ذلك حيث أصبحت مسؤولية الدولة هي الأصل وعدم المسؤولية هو الاستثناء ولاحظنا أن نظرية أعمال السيادة هي أخطر الاستثناءات الواردة على مبدأ المشروعية وأن هذه النظرية هي نظرية قضائية من صنع مجلس الدولة الفرنسي وقد كونها المجلس لاعتبارات تاريخية وظروف سياسية ، ومن قبيل انتهاج سياسة قضائية مرنة وحكيمة في علاقته بالدولة ، ولابد لنا من التطرق الى أهم النتائج التي توصلنا إليها من خلال بحثنا هذا إضافة الى مجموعة من المقترحات وذلك لاعتقادنا بأهميتها

العولمة والية التقارب العربي دول مجلس التعاون لدول الخليج العربية

إن دراسة أداء الدول العربية في مؤشرات التقارب أثبتت ضعف الأداء الاقتصادي للدول مع بعض الطفرات القليلة حيث أن مؤشر النمو الاقتصادي لم يشاهد تقدماً ملحوظاً كذلك الحال بالنسبة للاستثمارات إذ تتصف نسبة تدفقات الاستثمار الأجنبي المباشر إلى الأقطار العربية بكونها تمثل نسبة قليلة جداً من مجمل حجم هذا الاستثمار على مستوى العالم أن هناك أموالا عربية هائلة تستثمر خارج الوطن العربي , وتمثل نسبة التجارة الخارجية مع أقطار العالم غير العربية بحدود ( 7, 93 % ) من إجمالي حجم التجارة العربية في الوقت الذي تكون فيه نسبة التجارة العربية البينية ( 3, 7 % ) من هذا الحجم وهذا إذا دل على شيء فإنما يدل على ضعف الق
