  • This paper aims to investigate the good reservoir quality and hydrocarbon potentiality of the Khatatba Formation, Qasr Field in the Shoushan Basin of the North Western Desert, Egypt by combining results from log-based petrophysical analysis, petrographic description and images from scanning electron microscope (SEM). Promising reservoir units are initially identified and evaluated through well log analysis of three wells in the field of study. Petrophysical results are then compared with petrographic and SEM images from rock samples to identify features that characterize the reservoir quality. Well log results show that Khatatba Formation in the study area has good sandstone reservoir intervals from depths ranging from 12848 ft to 13900 ft, with good effective porosity records of 13-15% and hydrocarbon saturations of greater than 83%. Petrographic analysis of these sandstone reservoir units indicate high concentrations of vacant pore spaces with good permeability that can be easily occupied by hydrocarbon. The availability of these pore spaces are attributed to pore-enhancing diagenetic features, mainly in the form of good primary porosity and dissolution. SEM images and EDX analysis confirmed the presence of hydrocarbon, therefore indicating a good hydrocarbon-storing potential for the Khatatba Formation sandstones.

  • The mycobiota of 160 hair and nail samples collected from 4 different governorates in upper Egypt were estimated using soil plate method for isolating keratinophilic and dermatophytic fungi. Twenty-three fungi were recorded on both hair and nail samples collected from the four governorates. Highest fungal diversity (20) was collected from Red Sea samples followed by Qena (18) and Aswan (17) while lowest fungal diversity was recorded from Sohage samples. The common genera were Aphanoascus, Aspergillus, Penicillium, Paecilomyces and Chrysosporium. The most prevalent species belonging to these genera were: A. fulvescens, Aphanoascus sp. A. flavus link, A. flavus var. columnaris, P. chrysogenium. P. lilacinus and C. sulfureum. True dermatophytes such as Nannizzia fulva appeared in $20{\sim}30%$ of the male samples.

  • The costume, considered as a manner of clothing, represents the distinctive character of a country, of an epoch, of a personage; and always it mirrors the vicissitudes of human civilization. It is interesting to study the costume of ancient Western Asia, its civilization and culture were transmitted to Egypt and Greece. The results obtained are as follows: 1. Loin clothes, tunics, wraps were in Western Asia. 2. Sleeves and Trousers has been the great contribution to costume. 3. The Art of dyeing, weaving, and embroidering were well known. 4. Tassels and Fringes were used in Western Asia. 5. Egypt and Greece were affected by Western Asia.

  • In this work, the reactor kinetics capability is used to compute the design safety parameters in a PWR due to complete loss of coolant flow during protected and unprotected accidents. A thermal-hydraulic code coupled with a point reactor kinetic model are used for these calculations; where kinetics parameters have been developed from the neutronic SRAC code to provide inputs to RELAP5-3D code to calculate parameters related to safety and guarantee that they meet the regulatory requirements. In RELAP5-3D the reactivity feedback is computed by both separable and tabular models. The results show the importance of the reactivity feedback on calculating the power which is the key parameter that controls the clad and fuel temperatures to maintain them below their melting point and therefore prevent core melt. In addition, extending modeling capability from separable to tabular model has nonremarkable influence on calculated safety parameters.

  • The Christianity that spread to Egypt in 3rd century in A.D. is called Copt. Coptic Church built a lot of monasteries along the lower stream of Nile River, which produced thousands of text and paintings. Ethiopia is well known for its worship to Virgin Saint Mary and produced many paintings of Virgin Saint Mary in different costumes. The pictures usually came in foldable small books containing 3 pictures. The paintings usually featured Virgin Saint Mary and Jesus Christ dressed as royalty in crowns, saints and angels. There are saints on white horse, mirroring the oriental influence on Coptic painting. This research will look into the patterns and colours on the Coptic textiles, mainly tapestry.

  • Aquatic fungi from four brackish water lakes; Edku, Burullus and Manzala lakes which are located at the northern region of Egypt and Qarun lake that located in El-Fayoum city are reported in this manuscript. Twenty-nine fungal species which belong to 19 genera of aquatic fungi were recovered from water samples collected from the studied lakes. The most frequently isolated fungal species were Chytridium conferrop, Allomyces throughout and Rhizoclosmatium globosum. Thraustochytrium amoeboidum and Leptolegniella exoosporus have a moderately occurrence frequency. The maximum fungal count of recovered aquatic fungi was recorded in Burrullus lake followed by EdKu, Manzala and Qarun lakes. This study was extended to test the ability of six selected aquatic fungi(Brevilegniella keratinophila, Blastocladiella cystogena, Chytridium conferrop, Entophlyctis variabilis, Schizochytrium mangrovei and Thraustochytrium rosin), to uptake the radionuclide from their culture medium as a step to biologically treat the waste water or solution with radio-cesium and radio-cobalt. Fifty seven of Cs-137 and 35% of Co-60 could be removed from liquid waste by the selected aquatic fungi.

  • 208 yeast strains were isolated from air at El-Minia city, Egypt. Using 22 morphologi cal and physiological merkmals, these strains were identified and assignned to eight species belonging to seven genera. Rhodotorula mucilaginosa and Cryptococcus albidus were the most dominant species followed by Debaryomyces hansenii. These yeast species occurred regularly, whereas other species appeared sporadically. Rh. rubra, Saccharomyces kluyveri and Rh. aurantiaca were also isolated from the sampled air. The results of this study showed that time, hight and area of air sampling affect composition and total counts of yeast microflora in the air.

  • A total of 455 food samples representing 22 different food types were collected from several localities at Alexandria province in Egypt. Aflatoxin B1 and aflatoxin M1 were detected in 5 out of 455 (1.1%) of these food samples. From the same samples 206 fungal isolates were obtained. Thirty two of these isolates (15.5%) were found to be aflatoxin producers. Aspergillus flavus was the dominant isolate, while Aspergillus parasaticus was also isolated from a few other food samples. Among locally consumed foodstuffs. Peanut (7.5%) and Milk powder (6.6%) were found to be a suitable substrates for aflatoxin production. The hygienic and public health significance of the isolated aflatoxigenic strains were discussed.

  • Four anthocyanins were isolated from the acidic alcoholic extract of Syzygium cumini fruits growing in Egypt: Pelargonidin-3-O-glucoside, pelargonidin-3,5-O-diglucoside, cyanidin-3-O-malonyl glucoside, and delphenidin-3-O-glucoside. They were identified by the chromatographic, TLC and PC, and spectral analyses, UV, $^1$H-NMR and FAB/MS. The fruits were found to contain 0.03 gm % anthocyanins calculated on fresh weight basis calculated by spectrophotometric assay. Cytotoxic activity of total alcoholic extract of the fruits was performed against several types of tumor cell lines using the SRB assay. The tested extract exhibited significant cytotoxic activity for MCF7 (breast carcinoma cell line) (IC$_{50}$= 5.9 ${\mu}$g/mL), while the IC$_{50}$ was > 10 ${\mu}$g/mL for both Hela (Cervix carcinoma cell line), HEPG2 (liver carcinoma cell line), H460 (Lung carcinoma cell line) and U251 (Brain carcinoma cell line).
