Circulation pattern of the Egyptian Mediterranean waters during winter and summer seasons

The water circulation of the Egyptian Mediterranean waters was computed during winter and summer seasons using the dynamic method. The reference level was set at the 1000db surface. The results showed that the surface circulation is dominated by the Atlantic water inflow along the North African coast and by two major gyres, the Mersa Matruth anticyclonic gyre and El-Arish cyclonic gyre. The results showed a seasonal reversal of El-Arish gyre, being cyclonic in winter and anticyclonic in summer. El-Arish gyre had not been previously measured. The geostrophic current velocity at the edges of the Mersa Matruth gyre varied between 12.5 and 29.1cm/sec in winter and between 6.5 and 13.1cm/sec in summer. The current velocity reached its maximum values (>40cm/sec) at El-Arish gyre. The current velocity at the two gyres decreased with increasing depth. The North African Current affects the surface waters down to a depth of 100m, and that its mean velocity varies between 6 and 38cm/sec.

Revolting Arts or Spatial Democracy: Performances of popular arts during the Egyptian Revolution?

This paper investigates how spatial practices of Public art performance had transformed public space from being a congested traffic hub into an active and animated space for resistance that was equally accessible to different factions, social strata, media outlets and urban society, determined by popular culture and social responsibility. Tahrir Square was reproduced, in a process of “space adaptation” using Henri Lefebvre’s term, to accommodate forms of social organization and administration.205 Among the spatial patterns of activities detected and analyzed this paper focus on particular forms of mass practices of art and freedom of expression that succeeded to transform Tahrir square into performative space and commemorate its spatial events. It attempts to interrogate how the power of artistic interventions has recalled socio-cultural memory through spatial forms that have negotiated middle grounds between deeply segregated political and social groups in moments of utopian democracy. Through analytical surveys and decoding of media recordings of the events, direct interviews with involved actors and witnesses, this paper offers insight into the ways protesters lent their artistry capacity to the performance of resistance to become an act of spatial festivity or commemoration of events. The paper presents series of analytical maps tracing how the role of art has shifted significantly from traditional freedom of expression modes as narrative of resistance into more sophisticated spatial performative ones that take on a new spatial vibrancy and purpose.

Survival or Sustainability? Contributions of Innovatively-Managed News Ventures to the Future of Egyptian Journalism

In the repressive political climate prevailing in Egypt in 2013-15, news ventures aspiring to high standards of reporting were forced to innovate. This paper analyses three Egyptian start-ups that experimented with novel revenue streams and news services during that period, to gain insights into their approaches to managing journalism. In the process it compares different criteria for assessing sustainability and concludes that, in adverse political environments, narrow economic measures of profitability and survival may give a misleading picture as to the sustainability of the kind of journalism conducive to democratic practice. Operating collaboratively, transparently and ethically may slow productivity and profitability in the short term while laying stronger foundations for durable relations among media teams, as well as with readers and advertisers, in the long run.

Egyptian wheat

Wheat as the major cereal crop in Egypt is the core of the government's food security policy. But there are rapid losses of the genetic resources of the country as a result of ongoing modernization and development. Thus we compiled the largest possible number of Egyptian accessions preserved in the world gene banks. In the present study we collected nearly 1000 Egyptian wheat accessions. A part from the Triticum species of the Egyptian flora four species have been found, which were recorded for the first time T. turanicum, T. compactum, T. polonicum and T. aethiopicum. To classify the Egyptian wheat species using morphological studies, 108 accessions were selected. Thereafter, these accessions were cultivated and evaluated morphologically to confirm the validity of the classified species. During the morphological evaluation study, a new case was noticed for the number of glumes in one of the Egyptian wheat accessions. Three glumes per spikelet were observed in a branched spike. This led us to assess the phenomenon in all varieties with branching spikes within the genus Triticum. All varieties which have branching spikes at least in some spikletes have three glumes. We considered the case of the third glume as indicator for the domestication syndrome. Also, a new case of other forms of branching in the genus Triticum was investigated, which was a compromise between true and false-branching. We called it true-false branching. Comparative anatomical studies were carried out between Egyptian Triticum species to investigate the possibility of using anatomical features to classify the Egyptian wheat species. It was concluded that it is difficult to use anatomical features alone to differentiate between two Triticum species, especially when they belong to the same ploidy level. A key for the identification of Egyptian Triticum taxa was established.

Assessment of the presence of Salmonella spp. in Egyptian dairy products using various detection media

Aims: To make a preliminary assessment of the incidence of Salmonella in Egyptian dairy products, and to investigate the effectiveness of various protocols for the detection of the pathogen in these products. Methods and Results: Samples of milk and related dairy products were randomly collected from local markets and examined for the presence of Salmonella. While most samples were free of the organism, isolates of Salmonella enterica subsp. enterica serovar Typhimurium PT 8 could be recovered from 'matared' cream specimens. These isolates were susceptible to antibiotics usually used to challenge infections caused by Salmonella. A combination of buffered peptone water, Muller-Kauffman tetrathionate broth, and brilliant green phenol red agar gave the best results for the detection of the pathogen. Selenite-cystine broth and Hektoen enteric agar were ineffective as an enrichment and a plating medium, respectively, in the isolation of Salmonella. A modified identification strategy that reduces the burden of serological testing of presumptive isolates is proposed. Conclusions, Significance and Impact of the Study: 'Matared' cream could be a vehicle for transmitting Salmonella. Using the above combination of media, beside the suggested modified confirmatory procedure, should increase the effectiveness and ease of the detection of Salmonella in milk and dairy products.
