Thirty five bottom sediment samples were collected in a grid pattern from Wadi Al-Arab Dam. The present study focuses on the levels of Mn, Fe, Cu, Zn, Cd, total organic matter (TOM) and carbonate content (CO(3)(-2)) in order to assess the extent of environmental pollution and to discuss the origin of these contaminants in sediments of the dam. Concentration data were processed using correlation...

Introduction: The large diurnal temperature swing on lunar surface makes it a harsh environment for operating highly sensitive science instruments such as broadband seismometers. At low-latitudes, surface temperature reaches ~380 K at the peak of a lunar day, while it falls below 100 K soon after the sunset [1]. It is a challenge to maintain stability of the instruments’ performance between the...

Detailed structural geological and related studies were carried out in a number of critical areas in the Proterozoic basement of eastern Egypt to resolve the structural pattern at a regional scale and to assess the general characteristics of tectonic evolution, orogeny and terrane boundaries. Following a brief account of the tectonostratigraphy and timing of the orogenic evolution, the major st...

The present work aims at identifying favorable locations for groundwater resources harvesting and extraction along the Wadi Feiran basin, SW Sinai Peninsula, Egypt, in an effort to facilitate new development projects in this area. Landsat ETM+, Radarsat-1 and PALSAR images of Wadi Feiran basin were used in this work to perform multisource data fusion and texture analysis, in order to classify t...

The goal of the present study is to evaluate the endemic situation of theileriasis in the different localities in Upper Egypt, and also to evaluate the efficacy of some drugs in treatment of acute and chronic theileriasis. A total of 120 cows showed clinical signs varied from rise of body temperature, nasal and ocular discharge, corneal opacity, diarrhea, pale mucous membranes, associated with ...

Human myiasis has been reported from various regions in the world. We report a human case of external ophthalmomyiasis caused by the larvae of a sheep nasal botfly oestrus ovis from Wadi Alhawasna, North Batina, Oman. A 9-years-old boy presented with symptoms of acute conjunctivitis. Five larvae were removed from his eye and sent for identification. The patient recovered completely after remova...

The anaerobic, halophilic, alkaliphilic, thermotolerant bacterium Natranaerobius trueperi was isolated from a soda lake in Wadi An Natrun, Egypt. It grows optimally at 3.7 M Na+, pH 9.5, and 43°C. The draft genome consists of 2.63 Mb and is composed of 2,681 predicted genes. Genomic analysis showed that various genes are potentially involved in the adaptation mechanisms for osmotic stress, pH h...

A structural and petrological study of the Late Proterozoic rocks in the Wadi Kid area, Sinai, Egypt indicates the presence of an extensional metamorphic core complex in the northern Arabian–Nubian Shield. Gneissic domes throughout the Arabian–Nubian Shield resemble the core complex of the Wadi Kid area and as a result, they are interpreted as extensional metamorphic core complexes. The presenc...
