Wild Plant Habitat Characterization in the Last Two Decades in the Nile Delta Coastal Region of Egypt
No full textEnvironmental and land-use changes put severe pressure on wild plant habitats. The present study aims to assess the biodiversity of wild plant habitats and the associated spatiotemporal environmental changes in the coastal region of Dakahlia Governorate following an integrated approach of remote sensing, GIS, and samples analysis. Thirty-seven stands were spatially identified and studied to represent the different habitats of wild plants in the Deltaic Mediterranean coastline region. Physical and chemical characteristics of soil samples were examined, while TWINSPAN classification was used to identify plant communities. Two free Landsat images (TM and OLI) acquired in 1999 and 2019 were processed to assess changes via the production of land use and cover maps (LULC). Moreover, NDSI, NDMI, and NDSI indices were used to identify wild plant habitats. The floristic composition indicated the existence of 57 species, belonging to 51 genera of 20 families. The largest families were Asteraceae, Poaceae, and Chenopodiaceae. The classification of vegetation led to the identification of four groups. Canonical Correspondence Analysis (CCA) revealed that electrical conductivity, cations, organic carbon, porosity, chlorides, and bicarbonates are the most effective soil variables influencing vegetation. The results of the spectral analysis indicated an annual coverage of bare lands (3.56 km2), which is strongly related to the annual increase in vegetation (1.91 km2), water bodies (1.22 km2), and urban areas (0.43 km2). The expansion of urban and agricultural regions subsequently increased water bodies and caused occupancy of bare land, resulting in the development of wild plant habitats, which are mostly represented by the sparse vegetation class as evaluated by NDVI. The increase in mean moisture values (NDMI) from 0.03 in 1999 to 0.15 in 2019 might be explained by the increase in total areas of wild plant habitats throughout the study period (1999–2019). This may improve the adequacy of environments for wild habitats, causing natural plant proliferation

Diversity and enterotoxigenicity of Staphylococcus spp. associated with Domiati cheese.
No full textA total of 87 samples of fresh and stored Domiati cheese (an Egyptian soft cheese) were examined for the presence of
Staphylococcus spp. Fifteen Staphylococcus isolates identified as S. aureus (2 isolates), S. xylosus (4), S. caprae (4), and S.
chromogenes (5) were recovered from 15 cheese samples. The S. aureus isolates were resistant to penicillin G and ampicillin,
and one isolate was also resistant to tetracycline. S. aureus isolates harbored classical staphylococcal enterotoxin (SE) genes
(sea and seb) and recently characterized SE-like genes (selg, seli, selm, and selo). One S. aureus isolate contained a single
SE gene (sea), whereas another isolate contained five SE genes (seb, selg, seli, selm, and selo). These results suggest that
Domiati cheese is a source for various Staphylococcus species, including S. aureus strains that could be enterotoxigenic
Experiencing the armed struggle : the Soweto generation and after
No full textIncludes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions
Conservation 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
Environmental management of quarries as waste disposal facilities
No full textProblems associated with the disposal of municipal solid waste have become a source of public concern worldwide as awareness of potential adverse environmental impacts and health threats from solid waste has increased. Communities are concerned about the generation and management of solid waste to the extent of refusing to allow new disposal facilities near their homes, often after witnessing the legacy of existing facilities. Under these conditions, the development of national policies for the management of solid waste becomes highly political, all while requiring appropriate technical solutions that ensure environmental protection and proper management plans that support an acceptable solution for the disposal of municipal solid waste. In some locations, the conversion of old quarries into well-engineered and controlled landfills appears as a promising solution to a continuously increasing problem, at least for many decades to come. This paper describes the environmental impacts associated with solid waste disposal in a converted quarry site and the mitigation measures that can be adopted to alleviate potential adverse impacts. Environmental management and monitoring plans are also discussed in the context of ensuring adequate environmental protection during and after the conversion proces

The Pherobase is intended for use by both scientific and non-scientific communities and currently contains "over 10000 entries, around 3000 molecules, and over 32000 static html pages that make it the world's largest database of behavior modifying chemicals." The site contains multiple Insect indices for such categories as Order, Family A-Z, and Species; References indices such as Discovery by Author, Discovery by Year, and References A-Z; and indices for Compounds, Compounds by Family, and Compounds by Genus. The site also contains a Contribution Form, and number of online forums relating to The Pherobase
Kursī de Dīma Wannūs : corps et critique sociale
No full textQuel-est le rapport entre critique sociale et individu chez les romanciers syriens aujourd'hui ? Ces écrivains ont-ils anticipé, dans leurs œuvres, les bouleversements touchant la Syrie depuis le mois de mars 2011 ?
Dans la production romanesque de ces écrivains, l'attention est portée sur l'univers intime des personnages, sur leurs relations avec les autres, sur leurs fragilités et leurs peurs. Pas de place pour l'idéologie : les personnages sont des entités complexes qui incarnent plusieurs aspects de leur société ; on n’observe pas de division nette entre les côtés lumineux et sombres des individus.
Je propose ici le roman Kursī (Bayrūt, Dār al-ādāb, 2009), de l'écrivaine Dīma Wannūs, en tant qu'exemple de cette écriture détachée de l'idéologie, mais abordant tout de même les aspects problématiques de la société syrienne contemporaine. La corruption, la dictature, l'absence du respect de la dignité et de la justice sociale représentées par Dīma Wannūs sont justement ce contre quoi le peuple syrien s'est soulevé en mars 2011.
Le protagoniste de Kursī incarne l'anti-héros, partagé entre lâcheté et arrivisme ; et même s'il fait partie du régime au pouvoir, il est détaché de sa propre société, seul et isolé. La déconstruction de son corps, mise en place par l'écrivaine, peut être lue comme une métaphore du pouvoir syrien, marqué par l'usage de la répression. Il en ressort un sujet décomposé, incapable de s'écouter et de s'exprimer à travers les mots. Toutefois, ce tašrīḥ al-ğasad, cette dissection du corps du protagoniste, ne nous empêche pas de le percevoir comme quelqu'un de très humain et de très fragile, donc pas seulement comme un personnage négatif. C'est justement la présence de ce double langage qui peut être considérée comme le préambule de ce qui, au début, avait été défini comme « Printemps arabe » en Syrie et qui semblait aspirer à dépasser le monolithisme de la violence pour laisser l'espace au langage de la compréhension et de l'accueil de la différence
DENATURALIZING CULTURE: SAYED KASHUA'S NEWSPAPER COLUMNS ON THE TOPIC OF PREJUDICE
No full textAbstract Discrimination is a recurrent topic in the work of the Israeli-Arab writer Sayed Kashua. In the last couple of years, Sayed Kashua has moved away from writing about the prejudice expressed by his own Israeli Muslim community towards the Israeli Jewish population to focus his attention instead on the prejudice shown by Jews against Arabs in Israel. Self-criticism has always been a hallmark of Sayed Kashua's work so this shift indicates a significant change in the columnist's perception of his own society. Based on a survey of various issues relating to Israeli society, such as the law, the educational system and language, as well as a theoretical review of authors who observe a mutual alienation of Arabs and Jews in Israel, this article analyses several of Sayed Kashua's recent columns in the Israeli newspaper Haaretz. It also investigates how the author understands prejudice and, in a singular and surprising way, expresses his concerns and solutions to this problem
