Bob Abel, pp. 67Dr. El-Sayed was born in Alexandria, Egypt. After secondary school, he went to the University of Alexandria for his B.S. (1949) in Oceanography. After his M.S., he went to the Scripps Institute of Oceanography on a Fulbright Fellowship. He received his PhD from the University of Washington. As professor emeritus at Texas A & M, he directs a project with the Cooperative Marine Research Program in the Middle East. A friend asked him to work on a biological project on Drake Passage, Antarctica.
He worked for several years on vessels from Argentina and was later assigned to a ship for the study of krill. The science team included specialists interested in different aspects of the ecosystem. This was the first of many trips, including those on the Atlantic Ocean, Pacific Ocean, and Indian Ocean. He wrote the book “The Historical Perspective of the Antarctic Marine Research.” This book addresses the studies on the productivity of krill, in addition to phytoplankton and how solar radiation, nutrients, and the depletion of the ozone affected the marine ecosystem. The UVB radiation had a deleterious effect on the survival of the phytoplankton and nanoplankton.
Dr. El-Sayed describes his associations with SCAR, BIMASS, SCORE, and other research organizations. He summarizes the phasing out of CFCs production. Because some phytoplankton are inhibited by solar radiation, the maximum concentration of chlorophyll is between 10 and 20 meters. As a member of the Nimbus Experimental Team, Dr. El-Sayed used the coastal zone color scanner to study the krill ecosystem.

A sedimentary depositional and diagenetic model of a Pleistocene/Holocene coastal formation in Alexandria, Mediterranean Sea, Egypt
No full textLate Quaternary deposition along the northwest coastal plain of Egypt was influenced by sea level fluctuations as documented by a succession of Quaternary carbonate ridges (up to eight or nine) running parallel to the present shoreline. This study focuses upon depositional and diagenetic aspects related to the last glacial cycle and aims to the reconstruction of the coastal sedimentary paleo-depositional environments of the “Gabal El-Kor Island”, located along the Mediterranean coast of Egypt near Alexandria. The sedimentary succession cropping out at Gabal El-Kor Island is interpreted as a part of the Pleistocene second coastal ridge, dated at about 100 Ka. This study revealed that during the last interglacial period (Marine Isotopic Stage 5, MIS 5), marine deposits mostly made of bioclastic grains and ooids were formed and their early diagenetic alteration was achieved under marine subaqueous conditions. After marine regression, during glacial periods, a phase of subaerial exposure followed. This was associated with transport and accumulation of the exposed carbonate sands from the shore inland by wind action. In the postglacial, the sea level rose up to its present level and a lagoon formed behind Gabel El-Kor Island. The most relevant diagenetic events took place in three distinct stages: MIS 5, between MIS 4 and MIS 2, and during the early and middle Holocene MIS 1. Salient diagenetic events refer to vadose, meteoric, and marine phreatic environments respectively
The Nile Valley of Egypt: A Mayor Active Graben that Magnifies Seismic Waves
No full textThe Nile valley and the Nile delta are part of the active rift that is probably connected with the Red Sea tectonism. This zone is characterized by small-to-moderate size earthquakes that have caused extremely severe damage to recent and historical constructions. The most vulnerable area along the Nile valley is the one of Cairo-Faiyoum. Small local and large distant earthquakes could be a source of huge socio-economic damage in this area. The loose soft alluvial sediments of the Nile Canyon are the main factor behind this potential damage because they may greatly amplify the ground motion, as demonstrated by strong ground motion modelling. The largest amplification is generally concentrated along the edges of the graben and occurs at frequencies between 1 Hz and 2 Hz. This may explain the huge damage caused by distant earthquakes during recent and historical times. The distribution of intensity values during the events of 1926 and 1992 is well correlated with the modelled spatial distribution of the spectral amplification
Deterministic seismic hazard in Egypt
No full textThe regional seismic hazard in Egypt is assessed using a deterministic approach based on the computation of synthetic seismograms at a set of gridpoints located at distances of 0.2 from each other. The main input for this computation are earthquake sources and structural models. The earthquake sources are parametrized using focal mechanisms, seismogenic areas and regional seismicity. A number of deep seismic profiles have been used to define the crustal structures. Similar sets of gravity profiles have been used to define the density of the layers. The peak displacement (DMAX), peak velocity (VMAX) and design ground acceleration (DGA) are chosen and plotted to construct the seismic hazard maps. There are similarities between computed and observed amplitudes of ground motion in terms of their values and spatial distributions. The results obtained from the deterministic and probabilistic approaches are comparable. The areas of high seismic hazard level are of great socio-economic importance

No full textConservation in an Islamic context a case study of Makkah
No full textThe 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

INVESTIGATING HOTEL OUTSOURCING IN THE EGYPTIAN HOTEL MARKET: REASONS, BARRIERS AND ACTIVITIES
No full textDue to the increasing importance of “Outsourcing” as one of the strategic management tools used by hotels worldwide, the current study attempts to assess hotel outsourcing in the Egyptian Hotel Industry by providing insights into the outsourcing drivers or reasons and the encountered barriers. The study also discusses the most common activities outsourced by hotels in Cairo and Sharm El Sheikh. A total of 48 participants including General and Department Managers working in four and five-star hotels, mainly in Cairo and Sharm El Sheikh participated in this study. The methods used to collect data included personal interviews using a structured questionnaire. The findings revealed that outsourcing occurs in a variety of hotel functions and departments including information technology, transportation services, health club, pest control, animation, security, reservation, as well as other activities. The main reasons for outsourcing in hotels were found to be access of external expertise, reducing costs and focusing on core activities. Although participating hotels showed interest to expand their scope of outsourcing some constraints are limiting their ability to do so. Lack of reliable suppliers, minimal knowledge concerning outsourcing adoption, possible risk of providing unqualified staff and hidden relevant costs represented the most significant barriers of outsourcing. Finally, the study presents a group of practical and academic recommendations
