The Mudargag area, 740 km 2 builds up two Neoproterozoic tectono-stratigraphic units separated by a NW trending subhorizontal thrust plane along which deformed rocks from both units are confined. The lower infrastructural unit is represented by the northern dome "A" of Wadi Hafafit culmination which forms a macroscopic ovalshaped asymmetrical antifromal domal structure with a fold axis extends over 10 km in a NW-SE direction. It is differentiated into four structural subunits composed of interlayered sequences, mainly of para-granite gneisses, psammitic gneisses and paraamphibolites with medium to high-grade metamorphic facies. Granite gneisses and psammitic gneisses dominate the lower and the upper subunits, respectively, paraamphibolites dominate the second subunit, whereas the third subunit has subequal proportions of psammitic gneisses and amphibolites. The upper suprastructural unit is represented by Shait ophiolitic mélange domain (SOMD), which comprises deformed normally faulted thin-skinned napped sequence of low-grade metamorphosed volcanosedimentary island-arc type assemblages incorporating dismembered ophiolite and partially carbonated serpentinite fragments. Petrographic examinations carried out on both dome "A" and SOMD show distinct evidences of polyphase deformation (D1-D3) in addition to tow metamorphic events (M1-M2). Field data revealed that the exhumation of the Hafafit culmination domes to which the present dome "A" is considered and the large-scale crustal extension of SOMD run within a left-lateral dominated transpressional wrenching of Najd Shear System.

The aim of this work is to develop an efficient plasma reactor for ozone production. The electrical characterization of the developed reactor, including the current-voltage waveform and the consumed power, is investigated at different reactor configurations (including ground-electrode width, number of electrodes, and volume of the reactor) and operating parameters (including the air flow rates and energy density). The performance of the developed reactor for ozone production is evaluated. It is observed that the consumed power increased linearly with increasing the ground-electrode width and the number of electrodes, while the reactor volume and the flow rates have no noticeable effect on the consumed power. It is also found that the increase of the plasma area by increasing the width of the ground electrode is preferable than its increase by increasing the number of electrodes. This is attributed to the decrease of the power loss in the dielectric material. In addition, an optimum size of the reactor is obtained, as the higher and the smaller ratio of the reactor volume to the plasma area are not efficient.

Data hiding is a major mechanism used for secure data transmission in computer networks. One of the most important branches in data hiding is Steganography. Steganography techniques concerns with hiding the secret data within the cover image in order to avoid detection. Least Significant Bit (LSB) technique is used widely in steganographic images. The traditional LSB method replaces some LSB of the cover image with the secret data. In this paper, a new method based on LSB for image steganography is presented. The goal of the proposed method is to increase the embedding capacity and enhance the stego image quality. We invert LSBs of the cover image depending on the value of the secret data. The experimental results of this study indicate that our method achieves high capacity and good imperceptibility quality of the stego image.

In the present study samarium 5-fluorouracil (5-FU) complex was prepared to enhance the effectiveness of the 5-FU drug. This complex was characterized by UV/VIS spectrometry high performance liquid chromatography and differential scanning calorimetry. Furthermore, the antitumor effect of the prepared complex was explored on the human colon cancer cell Caco2 via evaluation of the cytotoxic activity of this complex through trypan blue cell viability. Apoptosis was also assessed through morphological changes, by Annexin V=PI flow cytometric analysis. The results revealed that the trivalent Sm enhance the 5-FU effect against the chemo-resistant colorectal carcinoma cell line.

Bisphenol A (BPA) is a chemical material that using in polycarbonate plastic that is widely used in daily life items. Several studies showed the adverse effect on the health of erythrocytes in both human and animals, while gallic acid (GA) is a known antioxidant capable of counteracting free radicals. In this study included 4 groups 10 rats each. The first was the control. The second received BPA in drinking water was given ad libitum at dose 40mg/kg.b.w. The third and fourth groups was given BPA by the same dose and by the same route in addition to receive GA in the diet at doses of 50 and 200 mg/kg.b.w, respectively. In erythrocytic hemolysate, the antioxidants: glutathione (GSH), activities of both superoxide dismutase (SOD) and catalase (CAT) were estimated. Also, lipid peroxidation (LPO) and carbonyl protein (CrPr) were determined. The results showed that BPA significantly increased LPO and CrPr and decreased the activities of CAT, SOD and the GSH content. However, the treatments of the BPA-intoxicated rats with GA reversed the erythrocytic oxidative damage and curtailed the decrease in antioxidants. In conclusion, the GA with both doses could attenuate the oxidative damage in erythrocytes of rats-treated with BPA.

Terrestrial isopods provide many important services for the ecosystem such as litter decomposition, nutrient mineralization. The present study aimed to make a survey of the distribution of isopods as leaf litter decomposers; in five different orchards during winter and summer and effects of some ecological factors on them. Isopod samples were collected by a tin quadrate sampler (20 X 20 cm.). Some of ecological factors were measured, air and soil temperature, humidity, pH, conductivity, soil water content and organic matter content. In the present study, five isopod species were recorded. Porcellio laevis and Porcellionides pruinosus were eudominant while the other three species were subdominant. P. laevis recorded the highest value of total isopods mean and standard deviation (SD) and that was in site 1. In addition, ANOVA and Duncan comparison showed that total abundance of isopods had no significant difference with the studied seasons but they significantly varied with sites during the whole period of investigation. Species richness and Shannon diversity index recorded their highest values in site 3, then in site 2. The clusters analysis of isopods abundance according to the five studied sites showed that: (a) Leptotrichus naupliensis and Chaetophiloscia hastata were the most similar species in the cluster of isopods abundance. (b) P. laevis was similar to P. pruinosus. Canonical Corresponding Analysis (CCA) of Isopoda and ecological factors revealed that: P. laevi shad positive correlation with air temperature followed by soil water content and soil temperature. Thus, P. laevis and P. pruinosus were the most dominant and abundant species and they both have the ability to live and acclimate with different conditions of the arable fields; of Assiut governorate more than the others.
