Levels and distribution of five B-6 vitamers(PMP, PM, PLP, PL, and PN) and pyridoxine $\beta$-glucoside conjugates(PN-glucoside) were examined in milk of American women who received supplements of 2.5 or 10mg PN HCl/d and of unsupplemented Egyptian women during the first six months of lactation. B-6 vitamer and PN-glucoside levels in human milk were determined by reverse-phase HPLC. Pyridoxal(PL), which has been reported to be the most rapidly absorbed form of vitamin B-6 and may facilitate bioavailability, was the predominant vitamer in human milk of all three groups. Pyridoxal made up 72% of total vitamin B-6 for the 2.5mg supplemented group, 76% for the 10mg group, and 59% for the Egyptian group. Level and Percent PL were significantly lower for Egyptian women. Mean growth of the two American groups was similar to each other and within the normal range of the NCHS reference, however, Egyptian infants showed growth faltering at 6 months. The Percent of PN-glucoside, a less bioavailable form of vitamin B-6 in humans was 1% in milk of American women and was 11% in Egyptian women and these values were significantly different. for Egyptian women, total vitamin B-6 levels in breast milk correlated Positively with animal protein intake(r=0.91) and percent PN-glucosides(r=0.53) and negatively with plant protein intake(r=-0.55). These findings showed that high plant protein intake was associated with low concentrations of PL and total vitamin B-6 in human milk.

Background: Available publications (e.g., theses, scientific reports, books and papers) about the elements of the Egyptian biodiversity during 2000-2018 were collected in a progress scientific report. The publications reported in this bibliography were collected from various sources including: site of the Egyptian Universities Libraries Consortium Portal, accounts of the biodiversity specialists on Research gate, direct contact with the national experts of the Egyptian biodiversity, libraries of some universities and research centers and others. The elements of the Egyptian biodiversity are classified into different categories. Results: Up till now, a total of 20,521 species were recorded in Egypt, of which insects have the highest contribution (48.7%), followed by fungi (12.1%) and vascular plants (11.5%). In a descending order, each of amphibians, viruses, reptiles, mammals, cyanobacteria, bryophytes, and bacteria have a minor contribution (< 1%). Based on the available data, Egyptian biodiversity contributes 1.3% of the world biota, although its area contributes only 0.7% of the world area. At a global scale, the most represented groups are algae (12.22% of the world figure), followed by cyanobacteria (6.08%) and birds (4.70%). On the other hand, the less represented are amphibians (0.14% of the world figure), flora (0.84%) and insects (1.00%). Conclusions: Some suggestions are recommended for preparing a phytoplankton checklist based on the rich available publications; further studies should be carried out on the lichen biodiversity in order to prepare acceptable verified checklist for this important group. In addition, paleo-biologists should work together to publish a book dealing with the Egyptian paleo-biology, such studies will lead to high ranking the Egyptian biodiversity.

This study aims to discuss how Egyptian learners of Korean perceive and categorize Korean vowels, how Koreans perceive Korean vowels they pronounce, and how Egyptian learners' Korean vowel categorization affects their perception and production of Korean vowels. In Experiment 1, 53 Egyptian learners were asked to listen to Korean test words pronounced by Koreans and choose the words they had listened to among 4 confusable words. In Experiment 2, 117 sound files (13 test words×9 Egyptian learners) recorded by Egyptian learners were given to Koreans and asked to select the words they had heard among 4 confusable words. The results of the experiments show that "new" Korean vowels that do not have categorizable ones in Egyptian Arabic easily formed new categories and were therefore well identified in perception and relatively well pronounced, but some of them were poorly produced. However, Egyptian learners poorly distinguished "similar" Korean vowels in perception, but their pronunciation was relatively well identified by native Koreans. Based on the results of this study, we argued that the Speech Learning Model (SLM) and Perceptual Assimilation Model (PAM) explain the L2 speech perception well, but they are insufficient to explain L2 speech production and therefore need to be revised and extended to L2 speech production.

The present work represents a technical guideline for decommissioning a disused teletherapy machine model Theratron-780 and contains category one ⁶⁰Co radioactive source. The first section predicts the dose rate from the source in case of normal and radiological emergency situations via FLUKA-MC simulation code. Moreover, the dose assessment for the occupational during the whole process is calculated and compared to the measured values. A suggested cordoned area for safety and security in a radiological emergency is simulated. The second section lists the whole process's technical procedures, including (preview, dismantle, securing, transport and storage) of the disused teletherapy machine. Results show that the maximum obtained accumulated dose for occupational were found to be 24.5 ± 4.9 μSv in the dismantle and securing process in addition to 3.5 ± 1.8 μSv during loading on the transport vehicle and unloading at the storage facility. It was found that the measured accumulated dose for workers is in good agreement with the estimated one by uncertainty not exceeding 5% in normal operating conditions.

Egypt has gone through a major metamorphosis following the Egyptian Revolution that began on 25 January 2011. The aim of this article is to analyze the influence of the aforementioned metamorphoses on the Egyptian Arbitration Law and Practice and to shed light on the recent developments of the latter. Whilst positive legislative amendments have been recently achieved with regards to enforcement of arbitral awards, it is crystal clear that the January 2011 Revolution has negatively impacted the jurisprudence of the Administrative Court of the Conseil d'Etat which has annulled several arbitration clauses enshrined in contracts related to privatization. However, save for disputes arising from administrative contracts, Egypt has been and shall remain a friendly seat of Arbitration as it possesses an arbitration-friendly legislation, its Ordinary Judicial Courts are familiarized with international arbitration practice and it has a prominent and famous arbitration Centre.

Many studies have done on Egyptian Clothing because its unique characteristic culture. However, I was facinated by the exhibitions of Tutankhamen burial treasures which were shown in San Francisco and New York in 1978 and 1979. I found out myself that there are several interesting aspects of clothing to compare 18th dynasty king, Tutankhamun and other dynasties in Egyptian culture. Therefore, I tryed to analized the Egyptian clothing including accessaries with theigr symbols durin 18th dynasty King, Tutankhamun. The most of people were shocked and amazed when they toured the exhibition of Tutankhamun articles which were the most incredible burial treasures in existence today. The body of the King has been embalmed, bandaged and fitted in eight layers of coffins with pure gold mask to represent the god Osiris. Among eight layers of coffins, one is pure solid gold in mummiform, two of mummiforms are made of compact wood covered with sheets of gold and inlaid with multi-colored glass-paste and semi-precious stones. The Egyptian belived that the soul continued to exist throughout eternity if it had passed on examination of its deeds on earth at a "Last Judgement" presided over by Osiris. They also believed that the mummified body could exist in the tomb as a habitation that the soul could revisited. Thus a proper burial was vital for a full existence in the hereafter. They buried dead person in the sealed vault of the tomb with some of the possessions he had used during his life time, such as his furniture, clothing and jewels. In this studies, I've tried to research to various clothings, and accessories with their symbols used during 18th dynasty king, Tutankhamun. The studies are shown as: I) Clothings of Tutankhamun dynasity of Kalasiris, Sheath skirt. Gala skirt, Loin skirt, Hike and Dalmatic. The Dalmatic was first seen in this dynasty. Probably the Roman Christian borrowed the Dalmatica from Egyptian Dalmatic. No where has the same design at the period. II) Egyptian of 18th dynasty Tutankhamun wore big headdress, broad collar necklace passium, pendants, armlets, rings and earrings with very beautiful, exquisite handcraft. They seem the first people who wore earrings in Egyptian history. III) The symbols of decorated items vulture, lotus...Upper Egypt Uraeus, papyrus...Lower Egypt scaravaeus, Nile Riber...rebirth man(Ankh), +...eternal life solar disc, gold...sun ostrich-feather...nobleness God, Horus' eye...protection against enemy IV) Also Egyptian prefered the straight line and a right angle which were the basic principles of architectural arrangement.

The purpose of this study is on the dance costume of ancient Egypt. First, after the present study looked onto a specialty of Egyptian dance, and then the present study classified Egyptian dress into type and form, quality of material and color tone, hair and headdress and other ornaments. Fundamentally, this study was intended to understand the traditional culture and to grasp the peculiarity of Egyptian dancing dress. This study was progressed as a theoretical research by using documents, photographs, literatures of museum, etc. The results of the study could be summarized as follows. Egyptian dancing featured the earliest form of stage dance in the world and improved religion dancing and sideshow dancing getting out of the form of primitive dance, and also there were professional dancers who developed highly skillful dancing technique. They played a role in disseminating it to many countries of the Mediterranean sea. Dancers of Egypt wore a variety of cloths like the general people. Accordingly, there were no big differences in qualify of material, color tone and other ornaments as well. Yet in accordance with improvement of dance, there was a show-up of clothing of professional dancers and changing of detail parts. So dancing dress was formed while distinguished from general clothing. Therefore, dancing dress of Egypt represents racial characteristics, activity, originality and pursues not authority, but respect of physical beauty or natural beauty.

The purpose of this study is to find the character of Cleopatra (69 B.C-30 B.C) by analyzing materials about Cleopatra, and to figure out symbolism and costume presented in movie . Costume of the main character, Cleopatra, compound the type of Egyptian traditional clothes, the change of it, and the trend in the 1960's. And, the symbolic meaning of it is also reinforced by adding ancient Egyptian myth to it. This kind of symbol is usually represented in Cleopatra clothing, especially in weaving pattern, embroidery, and ornament. And color of the clothes not only have their on predominance, but also can have their meaning fade away by mixed with each other, and also the shape has relation with the meaning of color. To sum up, the color and pattern of ancint Egyptian Cleopatra as alive formalize the power that come from coherence with the sun god in the center, which a used to maintain the power of the king. Costume in movie also contained color and pattern as a symbol of religion to symbolize the absolute power of king. These kinds of symbols are reemerging through historical recurrences and exotic interests.

The objective of the present study was to evaluate the anticancer and radio-sensitizing efficacy of a Withania somnifera extract/Gadolinium III oxide nanocomposite (WSGNC) in mice. WSGNC was injected to solid Ehrlich carcinoma-bearing mice via i.p. (227 mg/kg body weight) 3 times/week during 3 weeks. Irradiation was performed by whole body fractionated exposure to 6Gy, applied in 3 doses of 2 Gy/week over 3 weeks. Biochemical analyses as well as DNA fragmentation were performed. Treatment of solid Ehrlich carcinoma bearing mice with WSGNC combined with ${\gamma}$-radiation led to a significant decrease in the tumor size and weight associated with a significant decrease in mitochondrial enzyme activities, GSH content and SOD activity as well as a significant increase in caspase-3 activity, MDA concentration and DNA fragmentation in cancer tissues. Combined treatment of WSGNC and low dose of ${\gamma}$-radiation showed great amelioration in lipid peroxidation and antioxidant status (GSH content and SOD activity) in liver tissues in animals bearing tumors. It is concluded that WSGNC can be considered as a radio-sensitizer and anticancer modulator, suggesting a possible role in reducing the radiation exposure dose during radiotherapy.
