    Global epidemiology and molecular biology of <i>Taenia multiceps</i>: a comparative meta-analysis and <i>in silico</i> analysis study

    No full text
    AbstractIn the present study, all published data on the epidemiology and molecular characters of Taenia multiceps were systematically collected from relevant databases (e.g. PubMed, Scopus, National Center for Biotechnology Information), and combined in various statistical and genetic analyses as a contribution to a better understanding of the epidemiology of this ubiquitous taeniid worldwide. While 5.8% of the key hosts (dogs) from various countries had T. multiceps, grey wolves displayed the highest prevalence (21.6%) among the definitive hosts. Small ruminants are the main intermediate hosts and carry the coenuri in various locations, but most commonly in the central nervous system (CNS). Cerebral coenuri were confirmed in 53% of sheep exhibiting neurological symptoms, and infected animals often had only a single coenurus in the brain. Sheep had a higher prevalence (8.8%) of CNS coenuri than goats (5.8%); however, extra-CNS coenuri were detected more frequently in goats than in sheep. In either case, the difference between sheep and goats was statistically insignificant. Analysis of 233 partial cytochrome oxidase subunit I nucleotide sections for T. multiceps revealed high haplotype and low nucleotide diversities. Fifty-one haplotypes were detected circulating in 6 geographic populations. China, Iran and Turkey had 2 major haplotypes, whereas Italy and Egypt shared 3. Haplotypes from Greece circulate worldwide, and displayed similar gene flow values when compared with the other populations. There were no distinct patterns for haplotype distribution in relation to the infected hosts or coenuri locations. The existence of genetic variants in T. multiceps was highlighted, but needs further studies.</jats:p

    Conservation in an Islamic context a case study of Makkah

    No full text
    The Holy Qu’ rān contains many injunctions for Muslims to respect and conserve the natural environment but few address the built environment. Habitat at the time of the Prophet (PBOH) was in the vernacular and relatively impermanent. The first habitat was the cave, the second the tent and then simple flat roofed buildings of post and lintel construction made of mud and rubble. Later buildings were not indigenous but reflected the architectural styles and techniques of Muslim pilgrims from beyond the Arabian Peninsula. Permanent exotic buildings were later erected as reminders of holy places and events. This work advances a case to restore and preserve historic and religious sites in Makkah, Saudi Arabia. Makkah is the destination for millions of Muslim pilgrims who annually pay homage to Allah during the occasions of Hajj, Ramadan and Umra. The tranquillity and peaceful ambience that one associates with the holiest of Islamic experiences have, over the years, given way to jostling crowds of people who must be expediently housed, fed, transported, and protected. Due to the lack of planning and the insensitive but profitable development of the city, Makkah is in grave danger of becoming a bustling metropolis instead of a sanctuary where pilgrims gather to perform their religious rites and reaffirm their dedication to Allah. The author calls for professional planning and international cooperation to guide future development for this expanding and sensitive area. The author's ideas are grounded in practical and aesthetic study, therefore, the political, environmental and economic issues are examined in relationship to religious, historic and artistic values. The author makes proposals for a future Makkah that would provide pilgrims with the physical comforts, security, and serene environment they deserve—without destroying the city they came to visit. The author discusses preservation and conservation in the western world and the need for their acceptance in Muslim countries, the former being an aesthetic and intellectual concept sustained by law and the latter being the prescribed free expression of the individual unhindered by material considerations. Both worlds are rapidly being overwhelmed by materialism, but body, mind and spirit combine in making us aware of our surroundings and the way in what we see around us has come into being

    A Master of Science thesis in Chemical Engineering by Doaa Salim Samhan Alkathiri entitled, "Development of Activated Carbon Fibers for Organic Removals," submitted in November 2017. Thesis advisor is Dr. Taleb Hassan Ibrahim and thesis co-advisor is Dr. Yehya Amin El Sayed. Soft and hard copy available.Phenols are classified to be one of the most hazardous pollutants found in wastewater. They are discharged into rivers, lakes and seas, causing adverse effects on the enviromental and human health. Adsorption is a well-known technique used to treat wastewater. Activated carbon fibers (ACFs) are highly microporous efficient adsorbents due to their small diameters, high surface area and excellent volumetric capacity. In this work, ACFs were produced using polyacrylonitrile (PAN) fibers using different methods and tools. The fibers were stabilized initially at 250°C followed by carbonization at 850°C at a heating rate of 10°C/min and under the flow of nitrogen gas at a flow rate of 135ml/min. The carbonized fibers were subjected to physical (carbon dioxide) and chemical (potassium hydroxide) activation. The results showed that chemical activation using 3:1 ratio of KOH (wt/wt) produced fibers with a higher surface area of 2885m2/g compared to the physically activated fibers (774m2/g). The synthesized ACFs (Syn-ACFs) were compared and characterized in terms of morphology, thermal stability, composition and pore characteristics using SEM, EDS, TGA, CHN and nitrogen isotherm (Quantachrome). Bench scale batch experiments were carried out to determine and compare the adsorption efficiency, optimum parameters and the capacity of Syn-ACF and commercial ACFs (C-ACFs) for p-cresol removal. The adsorption optimum conditions using Syn-ACFs are: Syn-ACFs dosage = 1 g/l, contact time = 30 minutes, temperature = 25°C and initial pH = 4.6. The adsorption study on (Syn-ACFs) gave a higher removal efficiency of 91.0% of p-cresol compared to 71.6% (C-ACFs) at a concentration of 350ppm. In addition, the adsorption isotherms of p-cresol on C-ACFs and Syn-ACFs were found to follow the Langmuir isotherm equation; however, Syn-ACFs revealed a higher adsorption capacity (500mg/g) compared to C-ACFs (294 mg/g) at 25°C. The Syn-ACFs regeneration method was evaluated thermally at elevated temperatures and chemically using ethanol and n-hexane solvents. The thermal regeneration at 600°C achieved a higher removal efficiency of 84% compared to n-hexane (78%). The Syn-ACFs were evaluated for the treatment of produced water to ensure a removal of 71.2%. The results indicated that Syn-ACFs could be used as an efficient adsorbent for p-cresol removal in wastewater.College of EngineeringDepartment of Chemical EngineeringMaster of Science in Chemical Engineering (MSChE

    Ibrahim El-Salahi: A Visionary Modernist

    No full text
    The first Tate Modern exhibition dedicated to African Modernism traces the life and work of Ibrahim El-Salahi. This major retrospective brings together 100 works from across more than five decades of his international career. The exhibition highlights one of the most significant figures in African and Arab Modernism and reveals his place in the context of a broader, global art history. The exhibition outlines the artist’s personal journey, beginning in Sudan in the 1950’s and followed by his international schooling at the Slade School in London. After a period of research and self-discovery, he returned to Sudan in 1957. There, he established a new Sudanese visual vocabulary, which arose from his own pioneering integration of Islamic, African, Arab and Western artistic traditions. El-Salahi lived in Qatar before settling in England in the 1990s. His recent paintings reflect his joy for life, his deep spiritual faith, and a profound recognition of his place in the world. Ibrahim El-Salahi: A Visionary Modernist is organised by the Museum for African Art, New York, in association with Tate Modern, London. The exhibition is curated by Salah M. Hassan, Goldwin Smith Professor, Cornell University. The presentation at Tate Modern is curated in collaboration with Elvira Dyangani Ose, Curator, International Art, Supported by Guaranty Trust Bank Plc. The exhibition first opened at the Sharjah Art Museum in May 2012 and travelled to the Katara Cultural Village Foundation, Doha, Qatar in October 2012. An illustrated catalogue accompanies the exhibition, edited by Salah M Hassan with contributions by Sarah Adams, Ulli Beier, Iftikhar Dadi, Hassan Musa and Chika Okeke-Agulu, as well as special texts by El-Salahi

    Structural adjustment in Egypt : the case of agriculture

    No full text
    This thesis assesses the appropriateness and effectiveness of the economic reform and structural adjustment programme adopted by Egypt in 1991. It also examines the main political and economic constraints of such policies. It argues that it is unlikely to provide sustainable or equitable growth. It also argues that privatisation programmes in Egypt have a limited effect on improving levels of investment and growth. It stresses the need to encourage new investment to increase the productive capacity of the Egyptian economy in order to generate sustainable growth. The thesis examines in particular, economic reforms in the agricultural sector. It focuses on assessing price reforms so as to enquire how evenly distributed the benefits have been among farmers with different sizes of land holding. Those with big farms are likely to gain more while very small farmers and the landless are likely to lose. Within agriculture the thesis assesses the impact of structural adjustment on Egypt's agribusiness community. This sector is economically fragmented, has limited effectiveness and is politically weak regarding its participation and its influence on economic policy. The thesis argues that the success Df this sector is based on the availability of a strong and effective state to provide the legal and regulatory. infrastructure needed for an effective market economy, to abolish administrative obstacles and to enhance investors' credibility. In short, the thesis maintains that sustaining the economic reform is based on reviving productive investments and enhancing state capacity and democratisation
