Synthesis of Gold Nanoparticles by using Batch Method and Study its Antibacterial Activity
...Show More Authors

The research involves preparing gold nanoparticles (AuNPs) and studying the factors that influence the shape, sizes and distribution ratio of the prepared particles according to Turkevich method. These factors include (reaction temperature, initial heating, concentration of gold ions, concentration and quantity of added citrate, reaction time and order of reactant addition). Gold nanoparticles prepared were characterized by the following measurements: UV-Visible spectroscopy, X-ray diffraction and scanning electron microscopy. The average size of gold nanoparticles was formed in the range (20 -35) nm. The amount of added citrate was changed and studied. In addition, the concentration of added gold ions was changed and the calibration curve was calculated used to estimate Au ions in different samples. The effectiveness of gold nanoparticles prepared according to Turkevich method was studied as antibacterial agents against E. coli bacteria. The minimum inhibition concentration of gold nanoparticles that inhibit bacterial growth was calculated using the broth dilution method, which is based on several dilutions to determine the inhibition concentration.

Assessment of image quality of cervical spine complications using Three Magnetic Resonance Imaging Sequences
...Show More Authors

Examining and comparing the image quality of degenerative cervical spine diseases through the application of three MRI sequences; the Two-Dimension T2 Weighed Turbo Spin Echo (2D T2W TSE), the Three-Dimension T2 Weighted Turbo Spin Echo (3D T2W TSE), and the T2 Turbo Field Echo (T2_TFE). Thirty-three patients who were diagnosed as having degenerative cervical spine diseases were involved in this study. Their age range was 40-60 years old. The images were produced via a 1.5 Tesla MRI device using (2D T2W TSE, 3D T2W TSE, and T2_TFE) sequences in the sagittal plane. The image quality was examined by objective and subjective assessments. The MRI image characteristics of the cervical spines (C4-C5, C5-C6, C6-C7) showed significant difference

The effect of deficiencies in the standards and tools used for the management of the banking system in the emergence of the financial crisis by focusing on the Basel 1and 2
...Show More Authors

The banking industry, as a result of the great challenges it faced, required continuous development of the principles of management, control and mechanisms used. The Basel Committee on Banking Supervision has played a leading role in legalizing many of these developments and has been able to contribute significantly to establishing a common framework for banking supervision, The central role in the various countries of the world is based on coordination between the various regulatory authorities and thinking about finding mechanisms to confront the risks faced by banks, recognizing the importance of the banking sector in the stability of domestic and international banking systems or the danger of this sector in the emergence of F

A numerical study to improve the position and angle of the producer gas injector inside the intake manifold to minimize emissions and efficiency enhancement of a bi engine
...Show More Authors

To develop a petrol engine so that it works under the bi-engine pattern (producer gas-petrol) without any additional engine modifications, a single-point injection method inside the intake manifold is a simple and inexpensive method. Still, it leads to poor mixing performance between the air and producer gas. This deficiency can cause unsatisfactory engine performance and high exhaust emissions. In order to improve the mixing inside the intake manifold, nine separate cases were modelled to evaluate the impact of the position and angle orientation inside the intake manifold on the uniformity and spread of the mixture under AFR=2.07. A petrol engine (1.6 L), the maximum engine speed (8000 rpm), and bi-engine mode (petrol-producer ga

The Israeli and American challenges for Palestinian Refugees Return and the suggested mechanisms to confront it " Analyzing study in the light of rules of the international humanitarian law "
...Show More Authors

The refugees' issue is the essence of the Palestinian cause as a political, legal and humanitarian one that afflicts every Palestinian, and its repercussions are inherited through generations, because of the suffering, displacement, misery and deprivation that the refugees still suffer. The State of Israel pay a lot of effort to prevent the Palestinians from this right, and is responsible for their plight and displacement because of the racist laws imposed and enacted by it, in addition to the bias of the United States of America alongside Israel in light of the weakness of the international community and the politics of the one pole. This requires the search for alternatives and solutions to enable the Palestinian refugees to exercise t

Legal basis of the innkeeper obligation to ensure the physical safety of the guest in Iraqi and Egyptian law: A comparative study with the French and English laws

The legal basis for the obligation of the innkeeper to ensure the safety of things does not pose any problem, because the comparative legislation was organized by explicit legal texts, but the problem arises with regard to the legal basis of the innkeeper's obligation to ensure the physical safety of the guest, as these legislation lacked explicit provisions about it, and left the organization of the general rules, which Open the door to jurisprudence, where the foundations laid by the jurists, within the scope of civil law, unlike the English legislator, which organized it as a general duty in the landlord law of 1957, and some consumer protection laws implicitly referred to the obligation of the innkeeper To ensure the safety of the bo

Novel Tamoxifen Citrate-Loaded Polymeric Nanoformulations for Improving Treatment and uses in medical applications: An In Vitro and In Vivo Study
...Show More Authors

Tamoxifen citrate (TAM) is one of the most regularly used therapy in hormone receptor-positive breast cancer. Although it is a successful treatment, there is a problem with its bioavailability, accordingly this study was designed to improve TAM solubility and reduce its associated toxicity. TAM-Loaded poly (D, L-lactide –co- glycolide) nanostructure (TAM-loaded PLGA) has been synthesized and employed both in vitro and in vivo experiments. The blood hemolysis induced by TAM- loaded PLGA was 4.6 % at 200 µg mL-1, indicating that this nano-construct led to increased red blood cell protection. DNA molecule integrity was assessed and results indicated that DNA strands were protected from destruction at 200 µg mL-1. T
