- Abstract
Egypt currently holds the record for the most retractions in the continent of Africa according to the Retraction Watch database, and the 2nd highest of countries in the Middle East. The purpose of this study was to analyse the retracted medical publications from Egyptian affiliations, in order to delineate specific problems and solutions. We examined databases including Pubmed, Google Scholar and others, for all retracted medical publications that were conducted in an Egyptian institution, up to the date of August 31st 2022. We observed for the reason(s) for retraction, number of citations of the retracted work, the length of time between publication and retraction, and where the work was published (journal, publisher and impact factor). 68 retractions were identified. Most retractions were from the speciality of Obstetrics and Gynecology (n = 22), followed by Anesthesia (n = 7). The top 3 reasons for retraction were unreliable results, FFP level misconduct, and duplicate publication. The number of retractions significantly increased over the years, especially in 2022. When taking into account the number of medical publications per institution, the institute with the highest rate of retractions was Mansoura University, while the lowest rate was Cairo University. The number of retracted medical Egyptian publications continues to increase over time, although they represent a small portion of the overall body of Egyptian medical research. Future studies on retracted articles should employ a methodology that considers the institutions where the studies were conducted. This could allow a better understanding of specific problems in certain countries or regions.

- Abstract
By the time children in low- and middle-income countries start primary school, large socioeconomic disparities are evident in children's learning and development. Both pre-primary and home environments can play important roles in influencing school readiness and can contribute to disparities in early childhood development, but there is limited evidence on their relative roles in low- and middle-income countries. This paper examines how pre-primary quality, stimulation at home, and early childhood development vary by socioeconomic status for pre-primary students in the Arab Republic of Egypt. The results demonstrate substantial socioeconomic inequality in stimulation at home, more so than in pre-primary quality and inputs, although there is variation in the degree of inequality across different dimensions of pre-primary quality. "Double inequality" is observed, where students with less stimulating home environments experience slightly lower quality pre-primary inputs. There are particularly large pre-primary inequities in structural quality (physical environment) and less inequity in process quality (pedagogy). These results suggest that targeted investments in pre-primary education in Egypt are necessary to reduce inequality in school readiness but are likely insufficient to close the socioeconomic status gap in children's development. Investing in interventions to improve vulnerable children's home learning environments, as well as investing in quality pre-primary, is critical to address disparities in children's development.

The invention of paper has had a significant impact on the world, particularly in the realm of artistic expression. From its earliest precursor, papyrus, used in ancient Egypt, to the development of papermaking in China, paper has played a crucial role in the communication of culture, the advancement of the written word, and the progression of art. Despite the rise of digital media and the push for a paperless society, paper remains important as a surface for all media and as a handmade art form. The evolution of papermaking techniques and its use in various artistic mediums, such as illuminated manuscripts, prints, and watercolors, has contributed to the democratization of art and the exploration of new artistic possibilities. Today, artists continue to value the tactile qualities of paper, even as we move towards a more digital future. [Extracted from the article]

- Abstract
With a view to identifying inclusive policies and good practices to respond to the many challenges that refugee students face to access higher education in their host country, this Policy Paper has conducted a review of available statistical data and literature. In addition, six selected countries with considerable refugee populations have been analysed more in-depth. They are: France, Ethiopia, Egypt, Germany, Norway, and Turkey. From this analysis, the paper presents inclusive policies and good practices from these countries and their higher education institutions by type of obstacle to accessing higher education. It concludes by presenting 15 recommendations on how host countries can support the access of refugees to their national systems, arguing strongly for an 'equality opportunity approach' in terms of national policies, and caring measures, at the level of higher education institutions.

- Abstract
This report presents the results of RTI International Education's study on teachers' guides across 13 countries and 19 projects. Using quantitative and qualitative methods, we examine how teachers' guides across the projects differ and find substantial variation in the design and structure of the documents. We develop a scripting index so that the scripting levels of the guides can be compared across projects. The impact results of the programs that use teachers' guides show significant impacts on learning outcomes, associated with approximately an additional half year of learning, showing that structured teachers' guides contribute to improved learning outcomes. During observations, we find that teachers make a variety of changes in their classroom instruction from how the guides are written, showing that the utilization of structured teachers' guides do not create robotic teachers unable to use their own professional skills to teach children. Unfortunately, many changes that teachers make reduce the amount of group work and interactivity that was described in the guides, suggesting that programs should encourage teachers to more heavily utilize the instructional routines designed in the guide. The report includes a set of research-based guidelines that material developers can use to develop teachers' guides that will support effective instructional practices and help improve learning outcomes. The key takeaway from the report is that structured teachers' guides improve learning outcomes, but that overly scripted teachers' guides are somewhat less effective than simplified teachers' guides that give specific guidance to the teacher but are not written word for word for each lesson in the guide.

- Abstract
Over the period 2007-2013, a series of undertakings were made to introduce fundamental elements of decentralized education finance to Egypt. In 2009, 8.4M Egyptian pounds (EGP) of the Government of Egypt's (GOE) budget was decentralized to every primary school in three pilot governorates. By 2013, EGP 1.2B of the GOE's money had been decentralized nationwide. This paper describes what these undertakings strived to achieve, what specifically was done to achieve these objectives, the degree to which these objectives were achieved, the reasons why they were achieved to the degree they were with particular attention paid to the institutional and political context within which these undertakings unfolded. The account of the technical work that was undertaken to decentralize these funds is important, but more important is the account of the interplay between the technical work, the fact that this work supported a GOE-led initiative, and the volatile political environment--pre-revolution, revolution, and post-revolution Egypt--in which the work was done for it is here where important lessons about reform emerge.

Adham, Raniah Samir and Lundqvist, Karsten Oster
- Abstract
Massive Open Online Courses (MOOCs) in the Arab World are still in their infancy. Many Arab countries are now starting to launch their MOOC platforms; however, there are only a few who have actually implemented such systems. This paper will explore online learning, in particular the rise of MOOCs around the world and their impact on the Arab World. The purpose of this paper is to give a true picture of the development of the first MOOC platforms in the Arab World. It will analyse in detail the concept, definitions, background, and types of MOOCs (xMOOCs and cMOOCs), as well as the main MOOCs platform in the Western and Arab worlds, and a timeline of the development of MOOCs. It will then observe the status of MOOCs in the developed world, opportunities in the Middle East, and the influence of Western MOOCs on the Arab world, from many perspectives, e.g. educational, religious, cultural and social.

In light of artificial intelligence and new technologies, organizations have to follow new ways of working with different skill sets to achieve strategic goals. Therefore, human resource analytics is the scientific solution that enables organizations to make important decisions related to human capital and strategic business and thus gain a competitive advantage. Through new technologies comes the role of big data, as it works to establish the reputation of human resources as a strategic business partner that makes decisions driven by analytics. Evidence-based decisions, therefore, all equal a significant competitive advantage. This conceptual paper aims to understand the relationship between human resource analytics and achieving a competitive advantage in the presence of big data. This study will use quantitative data through a survey list that will be distributed to middle managers and human resources employees of the telecommunications company sector in Egypt.

10. Education Finance in Egypt: Problems and a Possible Solution. Occasional Paper. RTI Press Publication OP-0017-1401

- Abstract
Egypt, currently in the throes of major political change, will likely undergo reforms of various sorts in the next few years. Some of these reforms are likely to give local entities, including schools, greater control over education finances. In 2007, the Government of Egypt began to decentralize some non-personnel recurrent finances from the center--the Ministry of Education and the Ministry of Finance (MOF)--to lower-level jurisdictions, including schools, using a number of simple and transparent enrollment- and poverty-based funding formulas. By 2010, a sizable amount of capital expenditure was also being transferred to lower levels of the system via similar equity-based funding formulas. Prior to these formula-based decentralization efforts, a large amount of education-related non-personnel recurrent finances had already been moving from the MOF to the "muderiyat," education offices at the governorate level of the system. Analysis of these latter allocations reveals that they are highly inequitable on an inter-governorate per-student basis, ranging from EGP 966 per student in New Valley to EGP 25 per student in 6th of October. This paper examines the nature and potential causes of this inequity and espouses a way in which these funds could be transferred using an equity-based funding formula that holds harmless those muderiyat that would lose absolute amounts of money under such a more equitable distribution scheme. A bibliography is included.

- Abstract
This issue paper, one in a series that United States Agency for International Development (USAID) produces, provides analytical input to policy makers and practitioners on ways to address the pressing educational challenges in the Muslim world. The paper summarizes the findings and guidance contained in a full report of a three month desk study that analyzed the strengths and weaknesses of secular and Islamic educational systems in 12 Muslim countries (Egypt, Morocco, Yemen, Bangladesh, Pakistan, Indonesia, Malaysia, Nigeria, Guinea, Mali, Senegal, Uzbekistan). It focuses particularly on access to and quality of secular and Islamic education. Key findings of the report are: (1) most countries studied have made significant strides in primary school enrollment in secular/public education systems, although secondary enrollment rates remain low; and (2) one of the strengths of Islamic schools in most of the countries studied is that they are highly accessible, and most do not appear to have links with extremist Islamic groups. The report concludes that the best educational strategies in Muslim countries encourage public and moderate Islamic school systems to complement each other to reach all learners with enriched content. It recommends ways to improve access to and quality within schools, noting that none of the countries studied, with the exception of Malaysia, has established an effective education system capable of providing universal access to quality education. Includes 14 notes. Annexes contain: "Summary of Country Education Profiles" and "Summary of Country Profiles of Islamic Schools." (BT)

- Abstract
In 2004, the United States Agency for International Development (USAID)-funded Educational Quality Improvement Program 2 (EQUIP2) began investigating community-based schools as a mechanism for reaching the underserved populations. The team identified nine models that successfully organized schooling in regions least served by the formal education system. These complementary education approaches rely on community, non-governmental, and ministry collaboration and present a promising response to the challenge of meeting the EFA goals of universal access, completion, and learning. Complementary Education models work in support of the formal public system, offering students an alternative route to achieving the same educational outcomes as students in the government schools. The programs are designed to feed students into the government system at various entry points and are large enough to exhibit many of the same characteristics as mainstream schools. Over time, the models have increased rates of attendance, completion, and learning among the populations they serve. This EQUIP2 working paper synthesizes the findings from the nine case studies of successful complementary education programs in Afghanistan, Bangladesh, Egypt, Ghana, Guatemala, Honduras, Mali, and Zambia. The research demonstrated that the programs are more cost-effective than government schools in delivering education services and that they achieve higher learning outcomes through adjustments in school size and location, curriculum and language of instruction, school management and governance arrangements, and teaching staff and instructional support services.

This study aims to investigate, analyze and conserve the general arrangement plan of the Egyptian royal yacht “Safra El-Bahr” from the National Archives of Egypt’s tracing paper collection. The yacht was specifically designed for Abbas II, the khedive of Egypt in 1894 A.D. The following analytical techniques were used for this study: pH value measurement, fungal testing, XRD, ATR-FTIR and SEM-EDX. Results revealed that the pH value of the plan paper is 6.5. Fungal testing proved the presence of Aspergillus Niger and Penicillium sp. The crystallinity index of cellulose in the historical paper increased compared to modern tracing paper indicating the occurrence of deterioration. The ATR-FTIR spectrum of the studied tracing paper revealed the presence of gelatin as a sizing material. The SEM investigation showed the effect of the natural ageing and surrounding environmental conditions on the surface morphology of the fibers. The EDX analysis revealed the use of kaolinite Al
2 Si2 O3 (OH)4 , Cl, NaOH and CaCo3 in paper manufacture. Copper carbonate (CuCO3 ) was used for the blue color. Conservation treatments conducted on the object included cleaning, removal of pressure sensitive tape, removal of adhesive residues, tear mending and lining. These processes revealed the aesthetic value of the general arrangement plan - screw yacht “SAFA-EL-BAHRE. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Paper coating plays an important role in the paper properties, printability and application. The nanocoating is a multifunction layer that provides the paper with unique features. In this work, nanocoating formulas were prepared using a green method and component. The nanocoating formulas were based on biopolymers nanostarch NSt and nanochitosan NCh (NCS) decorated with Egyptian kaolinite Ka doped with zinc nanoparticles NCS@xka/ZnONPs (x represents different ratios) support for multifunctional uses. The nanocoating formulas were characterized using a physiochemical analysis as well as a topographical study. FTIR, XRD, SEM and TEM techniques were used. Additionally, the antimicrobial activity of the tested samples was assessed against six microorganisms including Gram-negative and Gram-positive bacteria. The prepared nanocoating formulas affirmed excellent antimicrobial activity as a broad-spectrum antimicrobial active agent with excellent activity against all representative microbial communities. The nanocoating with the highest ratio of Ka/ZnONPs (NCS@40 ka/ZnONPs) showed excellent antimicrobial activity with an inhibition percentage of more than 70% versus all microorganisms presented. The paper was coated with the prepared suspensions and characterized concerning optical, mechanical and physical properties. When Ka/ZnONPs were loaded into NCS in a variety of ratios, the characteristics of coated paper were enhanced compared to blank paper. The sample NCS@40 ka/ZnONPs increased tensile strength by 11%, reduced light scattering by 12%, and improved brightness and whiteness by 1%. Paper coated with NCh suspension had 35.32% less roughness and 188.6% less porosity. When coated with the sample NCS@10 ka/ZnONPs, the coated paper's porosity was reduced by 94% and its roughness was reduced by 10.85%. The greatest reduction in water absorptivity was attained by coating with the same sample, with a reduction percentage of 132%., (© 2023. The Author(s).)

CESAREAN section , *DELIVERY (Obstetrics) , *MIDWIVES , *CITIES & towns , *NURSE supply & demand - Abstract
Cesarean delivery rates are rapidly increasing in Southeastern Europe (to more than 60%), North Africa (with a rate as high as 72% in Egypt), and in urban areas in Southern Africa (a rate of over 50% in Lagos, Nigeria). Data on the background to these increases are scarce, but likely to include poor birthing facilities in general hospitals, convenience for the doctor, private medicine, fear of litigation, socioeconomic status, shortage of midwives and nurses, and disappearance of vaginal instrumental deliveries. Options to reverse cesarean delivery trends are discussed. In this context there is a need to be better informed about how women are being counseled regarding vaginal or cesarean delivery. The long-term consequences in subsequent pregnancies for mothers and children may well be largely ignored, while these risks are highest in LMICs where higher birth numbers are desired. FIGO has begun discussions with obstetric and gynecologic societies, healthcare bodies, and governments in several countries discussed in this article, to find ways to lower the cesarean delivery rate. The requests came from the countries themselves, which may prove beneficial in helping advance progress. [ABSTRACT FROM AUTHOR]

- Abstract
Of the nearly 14,500 nongovernmental organizations (NGOs) now registered with Egypt's Ministry of Social Affairs, 25% are inactive, 3% are less than 3 years old, and 7% are private member associations. The Egyptian government's promotion of specific social programs and service models in the NGO sector began after the October War of 1973. Egyptian NGOs, which are primarily politically neutral, fall into five categories: community development associations; religious (Muslim and Christian) welfare associations; private member associations; nonreligious social welfare associations; and scientific and public cultural organizations. In 1992, Egypt's NGO sector had an estimated total annual revenue of $85-110 million (U.S.), with private donations and activity (user) fees accounting for two-thirds of those revenues. Key NGO services and activities include the following: day care programs, sewing classes, health services, aid to widow-headed households, skills training and productive activities, general education, and religious instruction. Most Egyptian NGO services aim to serve the middle and lower-middle classes rather than the poor. The leaders and members of Egyptian NGOs are overwhelmingly male. NGO services are concentrated in urban areas. The sector is characterized by rivalries between associations at both the community and national levels.

The degradation and embrittlement of paper is due to the depolymerization of cellulose fibers; this is induced by acidity and oxidation. An important part of dealing with these chemically unstable materials is the neutralization of acid and deposition of a buffer reservoir to protect the fibers from introduction of acid in future. Paper deacidification is a fundamental process for achieving this goal. Any deacidification method chosen must be able to treat large numbers of items, safely, quickly and cheaply. The main goal of this paper was to investigate the effect of two deacidification solutions, which have never been used in Egypt, on the chemical and physical properties of different types of paper in order to find an alternative to Calcium hydroxide the most common deacidification method used in Egypt. Magnesium salts have been chosen to produce two deacidification methods, one of them in aqueous media, and the other in nonaqueous media; however, the magnesium has excellent deacidification properties and never have been applied in Egypt before. This paper is concerned with the Evaluation of Magnesium Bicarbonate (MBC) and Methyl Magnesium Carbonate (MMC), as neutralization agents, on the stability of paper substrate before and after accelerated ageing. Deacidification of acid paper samples (old book and newspaper) coming from wood pulp (20 century) and whatman paper samples, has been carried out with elaborate findings. Examinations and scientific analyses have been used in the assessment of treated samples, to figure out the efficacy of the two methods on the paper stability. Both methods have adequate deacidification properties; the pH value of paper has increased after deacidification. Mechanical testing and Fourier-transform infrared spectroscopy (FTIR) have proven considerable stability of mechanical and chemical properties of deacidified paper after accelerated ageing.

- Abstract
The first universal library in history, the Alexandrian Library, was established in the fourth century B.C. in Greece and disappeared in the third and fourth centuries A.D., according to various accounts. In an attempt to preserve Egypt's historical heritage, the Egyptian government has decided to build a new library in its place--the Bibliotheca Alexandrina. The new Alexandrian library will be a public research library whose purpose and collection will be designed to enrich the cultural development and heritage of Egypt, the Mediterranean region, Africa, and the Arab world. It will provide a link to the world's major research libraries utilizing all modern forms of technology for the acquisition, storage, transfer, and dissemination of information. The library is scheduled to open in 1995. This report presents the history of the ancient Alexandrian library, accounts of the Alexandrian librarians, the library collection (which represented writings from a variety of civilizations), and theories about the library's demise. Descriptions of the new Bibliotheca Alexandrina's mission statement, its proposed site (Alexandria, Egypt), organizational structures and functions, collection subject orientation, automation details, and its International School of Information Studies (ISIS) are presented. Details of the international architecture competition, which determined the winning architectural design of the new library, include a description of the competition's theme, a list of the judges, and the cost estimates of the project.

- Abstract
The European Training Foundation's (ETF) approach to promoting systemic and systematic quality assurance in vocational education and training (VET) is set out in this working paper. Quality assurance in VET is summarised by the ETF as the measures established to verify that processes and procedures are in place, which aim to ensure the quality and quality improvement of VET. The ETF uses the following definition of VET: "education and training which aim to equip people with knowledge, know-how, skills and/or competences required in particular occupations or more broadly on the labour market." The intention of this working paper is to serve as a resource for ETF staff and its function is to support a common ETF approach to promoting quality assurance in VET in partner countries. The paper will be made available to a wider audience with an interest in quality assurance in VET. ETF partner countries have signaled the need for more effective quality assurance measures to help improve the quality and relevance of VET outcomes. They aim to strengthen quality assurance policies and measures that support the development of good VET governance and management, good qualifications systems, good qualifications and good learning environments facilitated by good teachers and trainers. The main purpose of this working paper is to guide ETF staff to support partner countries in their endeavours to develop further their approach to quality assurance in VET. The paper has five chapters. The background to present-day quality assurance is presented in Chapter 1. Concepts important to the understanding of the ETF approach to quality assurance in VET are reviewed in Chapter 2. In Chapter 3, the evolution of European policies for quality assurance is summarised. The "status quo" of quality assurance policy and practice in ETF partner countries and reform needs and challenges, as presented in the Torino Process reports, are discussed in Chapter 4. Chapter 5 presents the ETF approach to promoting quality assurance in VET development, based on the conceptual framework set out in the preceding chapters. (A bibliography is included.)

The study basically aimed to identify how the Egyptian paper and electronic newspapers dealt with phenomenon of child abduction in Egypt in terms of form and content, and to identify the issues raised by the newspapers in the context of their discussion of phenomenon of child abduction. The problem of the study lies in the main question: How do the Egyptian paper and electronic newspapers deal with the phenomenon of child abduction during the period from January 2013 AD to January 2018 AD? The study is one of descriptive studies, it used the survey method, the comparative method, and the content analysis tool to collect data, and it represents the community of the analytical study in All the issues issued by (Al-Ahram & Al-Wafd) newspapers as samples of newspapers, and (Mesr al-Arabiya, alMesreen) newspapers as representatives of e- newspapers, In the period from January 2013 AD to January 2018 AD, in order to represent one of the most stages which the cries gone through, however, the total study sample of the newspapers reached (240) per newspaper, and one of the most important reasons for choosing this period of time is spread of phenomenon of child kidnapping in this period. The study found that the journalistic treatment to the problem, provided by the study newspapers for the phenomenon, was far away from ethics and standards of professional Journalistic practice. The study recommended giving attention to treatments of an explanatory and investigative nature and strengthening the status of opinion writing in Egyptian newspapers. [ABSTRACT FROM AUTHOR]

The aim of this work is to evaluate the potency of sorghum stalks as an alternative fiber for pulp and papermaking for the first time in Egypt. Sorghum Kraft pulp was bleached using D0EOD1 sequences to achieve a final high brightness and suitable mechanical strength. The results revealed that pulping alkali of 14% Na2O concentration is the best choice. In addition, this percentage preserved high pulp brightness with a value of 86 ISO together with low fiber degradation besides imparting a high mechanical strength to the product. So, sorghum bagasse can be utilized as an important available low‐cost non‐wood fiber for paper industry. [ABSTRACT FROM AUTHOR]

Egypt currently holds the record for the most retractions in the continent of Africa according to the Retraction Watch database, and the 2
nd highest of countries in the Middle East. The purpose of this study was to analyse the retracted medical publications from Egyptian affiliations, in order to delineate specific problems and solutions. We examined databases including Pubmed, Google Scholar and others, for all retracted medical publications that were conducted in an Egyptian institution, up to the date of August 31st 2022. We observed for the reason(s) for retraction, number of citations of the retracted work, the length of time between publication and retraction, and where the work was published (journal, publisher and impact factor). 68 retractions were identified. Most retractions were from the speciality of Obstetrics and Gynecology (n = 22), followed by Anesthesia (n = 7). The top 3 reasons for retraction were unreliable results, FFP level misconduct, and duplicate publication. The number of retractions significantly increased over the years, especially in 2022. When taking into account the number of medical publications per institution, the institute with the highest rate of retractions was Mansoura University, while the lowest rate was Cairo University. The number of retracted medical Egyptian publications continues to increase over time, although they represent a small portion of the overall body of Egyptian medical research. Future studies on retracted articles should employ a methodology that considers the institutions where the studies were conducted. This could allow a better understanding of specific problems in certain countries or regions. [ABSTRACT FROM AUTHOR]- Published

This article discusses four inventions that have had a significant impact on communication: papyrus paper, the printing press with movable type, the telephone, and the internet. Papyrus paper, invented in Egypt around 3000 B.C., provided a simpler way to record and share ideas. The printing press with movable type, invented in Germany in 1439, made books more affordable and accessible, leading to an explosion in learning and innovation. The telephone, invented in the United States in 1876, revolutionized communication by allowing real-time conversations over long distances. Finally, the internet, invented in the United States in the 1960s, has become an integral part of how we live, learn, and work, connecting people worldwide and making the world seem smaller.

- Abstract
This paper demonstrates the analytical importance of employing output-based measures of school quality. The empirical analysis employs data collected in a longitudinal survey of primary school students in Egypt during 2 academic years, 1978-79 and 1979-80. School quality and grade completion are shown to be directly linked, leading to very different perspectives on educational policy in developing countries. Unique panel data on primary school age children in Egypt permit estimation of behavioral school dropout models. Students perceive differences in school quality, measured as expected achievement improvements in a given school, and act on it. Specifically, holding constant the students own ability, achievement and earnings prospects, a student is much less likely to remain in school if attending a low quality school rather than a higher quality school. This individually rational behavior suggests that arguments about a trade-off between quality and access to schools may mis-state the real issue and lead to public investment in too little quality. Further, because of this behavioral linkage, there is an achievement bias such that common estimates of rates of return to years of school will be overstated. The paper includes: (1) Foreword; (2) Abstract; (3) Acknowledgments; (4) Introduction; (5) Egyptian Schooling; (6) Overview of Model--School Quality, and Opportunities Outside School; (7) Estimation Samples; (8) Basic Empirical Results--School Quality, Earnings Opportunities, Probability of Market Work, and School Dropout Behavior; (9) Conclusions; and (10) 32 references.

- Abstract
This analytical report on higher education in Egypt argues that Egypt's policy must take account of the realities of declining government budgets and employment and the need to rely increasingly on the private sector, which must become more competitive internationally. Previous policy, which expanded higher education rapidly (despite a persistently high rate of illiteracy) and guaranteed jobs to university graduates, resulted in over-enrollment and poor educational quality. Currently, the government's strategy is to stabilize the number of university students and raise the quality of instruction, expand the role of two- and four-year technical institutes, increase the use of pedagogical materials in instruction, and promote innovative interdisciplinary programs that stress problem solving and applied work. Following an executive summary, the report is put in context by reviewing Egypt's development strategy in the 1990s. The following sections cover the history of higher education in Egypt; and higher education performance and the determinants of performance (including quantity, quality, internal and external efficiency, and equity). A concluding section examines current responses and reforms of the government, employers, students, and universities. A statistical annex provides data tables. (Contains 18 references.) (DB)

Over the past years, non‐stop research and development has continued to find the most suitable bleaching sequence for each source of fibrous raw materials, both wood and non‐wood, by improving mixing technology. In this work, the role of ozone bleaching and nano‐filler loading on the quality of papermaking from sorghum bagasse as an alternative available agriculture residue in Egypt was studied. We bleached the sorghum Kraft pulp using D0EOD1 and ZEOD sequences to achieve a final high brightness and suitable mechanical strength. The quality of the pulp obtained is proved to be excellent for paper industry. CaCO3 nano‐filler was applied on bleached pulp sheets in order to decrease the production costs through increasing filler loading. The FTIR spectrum of this filler loaded on the pulp indicates the existence of some kind of bonds between them. In addition, it was observed that the particle size was reduced after the milling process. The nano‐filler significantly enhanced the retention and consequently all the paper optical properties. Addition of nano‐filler loading leads to improving brightness, opacity, scattering coefficient, and acceptable mechanical strength of sheet formation needed for papermaking. It is of interest to note that adopting the ZEOD sequence gave a brightness increase from 86 ISO in case of DoEOD1 to 90 ISO. Furthermore, the paper sheets filled with the nano‐filler, according to this sequence, improved the brightness to be 94.6 ISO, a value higher than that produced by the standard commercial filler of 93.3 ISO.

The use of various types of radioactive drugs has increased the effectiveness of nuclear medicine. Technetium-99m (
99m Tc) radiopharmaceuticals are in widespread use owing to the availability and affordability of99 Mo/99m Tc generators and the variety of kits for formulating the desired products. Together, they provide an array of specific tools for diagnosing a large number of diseases affecting the Heart, Kidney and major organs of the body such as the bones, brain, liver, parathyroid, and thyroid. Nuclear medicine requires high quality radiopharmaceuticals and kits that are safe for administration and efficacious for a given application. Since radiopharmaceuticals are intended for human use, it is imperative that they undergo quality control measure. This paper presents various parameters affecting labeling efficiency of radiopharmaceuticals and describes the procedures of preparing from four selected kits. Details of the ingredients are also included. The procedures described here can be used to develop manuals and standard operating procedures in Egypt. This study is expected to serve as a guide to radiopharmaceutical manufacturing centers of such kits. Four kits namely: MIBI, DTPA, MDP, and DMSA are used. Paper Chromatography was involved to disparate the polar and non-polar part of the kit-solution. Quality control testing assures purity, integrity, potency, product identity, biological safety and efficacy of radiopharmaceuticals. The success of diagnostic radiopharmaceutical has been reflected in the quality of images of diseased site. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The main objective of the present study was to improve the quality of pulp and paper industrial wastewater of two local mills RAKTA and El-Ahlia, Alexandria, Egypt, and to bring their pollutant contents to safe discharge levels. Quality improvement was carried out using integrated chemical and biological treatment approaches after their optimization. Chemical treatment (alum, lime, and ferric chloride) was followed by oxidation using hydrogen peroxide and finally biological treatment using activated sludge (90 min for RAKTA and 60 min for El-Ahlia effluents). Chemical coagulation produced low-quality effluents, while pH adjustment during coagulation treatment did not enhance the quality of the effluents. Maximum removal of the tested pollutants was achieved using the integrated treatment and the pollutants recorded residual concentrations (RCs) of 34.67, 17.33, 0.13, and 0.43 mg/l and 15.0, 11.0, 0.0, and 0.13 mg/l for chemical oxygen demand (COD), biochemical oxygen demand (BOD5), tannin and lignin, and silica in RAKTA and El-Ahlia effluents, respectively, all of which were below their maximum permissible limits (MPLs) for the safe discharge into water courses. Specific oxygen uptake rate (SOUR) and sludge volume index (SVI) values reflect good conditions and healthy activated sludge. Based on the previous results, optimized conditions were applied as bench scale on the raw effluents of RAKTA and El-Ahlia via the batch chemical and the biological treatment sequences proposed. For RAKTA effluents, the sequence was as follows: (1) coagulation with 375 mg/l FeCl3, (2) oxidation with 50 mg/l hydrogen peroxide, and (3) biological treatment using activated sludge with 2,000 mg/l initial concentration and 90 min hydraulic retention time (HRT), while for El-Ahlia raw effluents, the sequence was (1) coagulation with 250 mg/l FeCl3, (2) oxidation with 45 mg/l hydrogen peroxide, and (3) biological treatment using activated sludge with 2,000 mg/l initial concentration and 60 min HRT. In conclusion, results confirmed that the application of the proposed sequential treatments removed almost all COD, BOD5, high molecular weight compounds, and silica from RAKTA and El-Ahlia influents and produced high-quality effluents, thus achieving the main objective of this study.

- Abstract
Case studies of study service activities (activities that adapt higher education more closely to the community) are examined. The document describes 21 such studies, one from each of 21 countries, undertaken by college students in the community. Background information is included on the origin, conditions, and need for study service in higher education, along with principles underlying the programs and concept of study service. Trends are also described concerning the development and refinement of objectives, the growth and expanded role of study service programs, the diversity of programs, and new forms of international cooperation. After identifying problem areas regarding study service, future prospects are suggested. It is claimed that study service programs have neglected some areas of action by focusing mainly on socioeconomic objectives (rural development and public health and hygiene), and educational objectives (elimination of illiteracy, and post-elementary activities). It is recommended that attention should be directed toward broader social and cultural problems. The case study countries are: Brazil, Canada, Costa Rica, Cuba, Czechoslovakia, Egypt, East Germany, Guyana, India, Indonesia, Israel, Mali, Mexico, Mozambique, Nepal, Poland, Rumania, Union of Soviet Socialist Republics, Tanzania, the United States, and Zambia.

- Abstract
Despite considerable progress by Middle Eastern and North African countries in improving opportunities for women to access and attain education at all levels, much remains to be done. This report focuses on three sets of highly inter-related determinants of access, achievement, and outcome--macro-level societal determinants, school characteristics, and family background characteristics--in seven representative Middle Eastern and North African countries: Egypt, Tunisia, Morocco, Jordan, Turkey, Saudi Arabia, and Kuwait. The research shows that the level of economic development of a country and the distribution of income have a much stronger impact than do Islamic and cultural values, while the size and growth rate of the population can place a major strain on school facility and resources. Sex-role stereotypes and the division of labor in the home and marketplace mean that expected returns from female education do not appear to justify the costs. Free, compulsory education and open admissions have led to major improvements in female education but have no guaranteed equity. Socio-economic background, parental education, family size, and family socialization exert a strong influence on educational attainment. Other key factors are a family's ability to cover the costs of education and forego the labor of the daughters. The availability and accessibility of schools and the quality of their programs and human resources have significant effects on female educational enrollment, continuation, quality, and outcome. All-girls schools have played a positive role under certain conditions. Because of the importance of female teachers and administrators as potential role models, their high rate of attrition and absenteeism calls for careful solutions. Contains 104 references. (Author)

Historical photographs play a significant role as records, documenting the various stages of the history of Egypt and reflecting our identity and social, cultural, and religious values. Silver gelatin prints were the dominant positive printing processes in the 20
th century. One of the most common forms of damage found among photographic collections is tears, which may result from improper handling and misuse, inappropriate storage, disasters, and other factors. In the past, tears were mended using pressure-sensitive tapes by amateurs and conservators. Over time, these tapes caused damage to the photographic surfaces since they oxidised, forming stains that are difficult and sometimes impossible to remove. Recently, many gel-based systems have been developed for use in the conservation of different cultural and historical materials, particularly paper artifacts. The aim of this research is to evaluate the efficacy of Klucel G and agar, as gel systems that are favoured by conservation specialists, in removing pressure-sensitive tapes from the surfaces of silver gelatin prints, as well as to study their effect on the photographs themselves. Organic solvents were added to the gel systems, and invaluable old photographs were used for this study. After treatment, samples were subjected to artificial ageing at a temperature of 80°C and 65% RH. Evaluation of the selected treatments was carried out through visual inspection, microscopic examination, colorimetric measurements, and attenuated total reflectance Fourier transform infrared spectroscopy. Results showed that both gel-based systems with mixed organic solvents gave great results compared to the conventional methods in terms of tape removal. However, colour change was detected in the case of agar gel-treated samples. Agarose gel may be a more proper option. [ABSTRACT FROM AUTHOR]- Published

In recent times, elevated urban linkages (EULs) have emerged as crucial components of urban development, cutting through the cities' urban fabric to accommodate the rapid expansion of urban cores and to facilitate traffic flow. However, these massive infrastructures have inadvertently given rise to urban lost spaces—vacant, inefficient areas within the urban fabric. Recognizing these lost spaces as untapped public assets, the paper explores sustainable development strategies to reclaim them into the urban fabric, transforming them into vibrant, multi-functional public spaces. The paper aims to achieve a set of urban design guidelines for rehabilitation design interventions which will be deduced into a comprehensive framework. This framework encompasses criteria for selecting appropriate approaches and types of rehabilitation design interventions, as well as design principles ensuring the desirability of the reclaimed space. The paper applies this framework to assess the El Sawy Cultural Wheel in Egypt, revealing it as a successful example of a reclaimed space. While positive aspects of rehabilitation design interventions are evident in terms of the approach and type of intervention in this case study, there are identified areas with shortcomings in fully implementing the design principles, if enhanced, could elevate the overall quality of the reclaimed space.

The liver samples were evaluated for chemical indicators of spoilage (pH, TVBN "Total Volatile base nitrogen", and TBA "Thiobarbituric acid") and some of the nutritional aspects (percentage of moisture, protein, fat, ash, and carbohydrates, as well as, gross energy (Kcal/100g) and cholesterol content (mg/100g), beside levels of iron (mg/100g). The obtained mean values of pH, TVBN (mg/100 g) and TBA (mg/kg) of the examined samples were 6.38 ± 0.01, 25.76 ± 0.44, and 0.65 ± 0.03, respectively. Of the examined samples, 92 % showed pH value exceeded the permissible limits of Egyptian standards; however, 88 % showed TVBN content within the set limit. The mean values of moisture, protein, fat, ash and carbohydrates (%) were 70.54 ± 0.11, 21.64 ± 0.08, 3.58± 0.12, 1.50 ± 0.018, and 2.74 ± 0.11, respectively. The calculated gross energy mean value was of 133.09 ± 1.06 Kcal/100 g. Additionally, the cholesterol and iron content mean values were 130.85 ± 2.17 mg/100 g and 16.07 ± 0.24 mg/100 g, respectively in the examined imported frozen liver samples. In conclusion, imported frozen liver sold in markets of Assiut city Egypt is of fair quality; it should be consumed sporadically and with care of TBARS, cholesterol and iron potential hazards.

PAPER ,EGYPTIANS ,INDUSTRIAL revolution ,PAPER industry ,WRITING materials & instruments - Abstract
This article discusses the history of paper. Paper originated in China in 105 A.D., though in 3500 B.C., Egyptians used a similar material called papyrus. Prior to the industrial revolution, paper was made by hand, but this was soon transformed from a labor intensive process into a mechanized industry ready for global mass production. As of 2005, the paper industry continues to grow, with industrialized nations accounting for about 87 percent of the world's paper output. It is said that paper is set to grow at a rate of 2.4 percent every year. INSET: Making paper.

- Abstract
Objective: Friction foot blisters are a common injury occurring in up to 39% of marathoners, the most common injury in adventure racing, and represent more than 70% of medical visits in multi-stage ultramarathons. The goal of the study was to determine whether paper tape could prevent foot blisters in ultramarathon runners., Methods: This prospective randomized trial was undertaken during RacingThePlanet 155-mile (250-km), 7-day self-supported ultramarathons in China, Australia, Egypt, Chile, and Nepal in 2010 and 2011. Paper tape was applied prerace to one randomly selected foot, with the untreated foot acting as the own control. The study end point was development of a hot spot or blister on any location of either foot., Results: One hundred thirty-six participants were enrolled with 90 (66%) having completed data for analysis. There were 36% women, with a mean age of 40 ± 9.4 years (range, 25-40 years) and pack weight of 11 ± 1.8 kg (range, 8-16 kg). All participants developed blisters, with 89% occurring by day 2 and 59% located on the toes. No protective effect was observed by the intervention (47 versus 35; 52% versus 39%; P = .22), with fewer blisters occurring around the tape on the experimental foot than under the tape (23 vs 31; 25.6% versus 34.4%), yet 84% of study participants when queried would choose paper tape for blister prevention in the future., Conclusions: Although paper tape was not found to be significantly protective against blisters, the intervention was well tolerated with high user satisfaction., (Copyright © 2014 Wilderness Medical Society.
