  1. Potentialities of in-situ leaching of uranium and copper ore material in west central Sinai, Egypt

    International Nuclear Information System (INIS)

    A low grade uranium-copper ore material is recently recorded in the Paleozoic sedimentary sequence in west central Sinai, Egypt. The host rocks composed mainly of siltstone, clay, sand and gravel. A number of secondary uranium and copper minerals have been reported including mainly uranophane, carnotite, meta-tyuyamunite and meta-autunite beside atacamite, para-atacamite and langite. Series of lab percolation leaching experiments in both vertical and horizontal columns have been performed using acid and alkaline leaching reagents. Due to the fact that the ore material is situated above the water table, the in-situ leaching technique is doubtful. However, other natural leaching methods especially heap and in place leaching could be proposed. (author). 23 refs, 12 figs, 4 tabs

  2. Geochemical studies of some uraniferous sedimentary rock varieties of west central Sinai, Egypt

    International Nuclear Information System (INIS)

    A new radioactive mineralization has been lately discovered in Wadi Nasib, west central Sinai. The radioactivity is essentially associated with the Lower Carboniferous sandstone, shale, clay, and gravel. The uranium and thorium distribution in some investigated samples showed that uranium content generally ranges from 105ppm to 5083ppm in the sandstone and siltstone respectively. However, thorium content ranges from nil up to 330 in some ferruginous siltstone and ferruginous sandstones respectively. The geochemical relationships between uranium and/or thorium and the other analyzed constituents including iron, copper, manganese, sulphate, soluble chlorides and organic matter, have been manifested. This geochemical study clarifies that the siltstones are the most radioactive rock type. The presence of uranium in the hexavalent state has been ascertained by the presence of secondary uranium minerals like uvanite, meta tyuyamunite, meta zeunerite, liebigite, and uranophane. At the same time, there are other radioactive minerals such as xenotime, atacamite, and jarosite. It has been concluded that the secondary uranium minerals may represent the oxidation products of the pre-existing uranium minerals in the basement rocks. The clay and shale components in the siltstones are the most suitable lithological facies for uranium trapping via absorption, concentration, and deposition stages

This study records beneficiation of low-grade silica sand deposits near Um Bogma at west central Sinai. The improvement techniques of ore dressing involving wet sieving, attrition scrubbing, decantation, gravimetric and magnetic separations have been applied depending on the physical properties of the constituents.

  4. Model equations for Calculating Rn-gas Concentrations in Air of Uranium Exploratory Tunnels, Allouga, West-Central Sinai , Egypt

    International Nuclear Information System (INIS)

    Gabal Allouga area is located some 40 km due east from Abu Zenima town on the east coast of the Gulf of Suez, West-Central Sinai, Egypt. A network of exploratory tunnels totaling 670m in length and approximately 2x2 m in cross section, were excavated within a paleosol clayey bed. They host (Fe, Mn)-, Cu-, and U-mineralizations. Portions of the tunnels are naturally ventilated and others portions are non-ventilated and show ground water seepage through fractures. Model equations were developed for calculating the Rn-gas concentrations in the air of the tunnels under dry conditions where Rn-gas transport is mainly by air flow through porous media as well as for wet conditions where Rn-gas transport is mainly by ground water flow into the tunnels. Under dry conditions the model calculated Rn-gas concentrations(15.2-60.6 PCi/1) are consistent with measured values by active techniques (3.26-22.85 pCi/1) and by SSNTD techniques (19-69.1 pCi/1) when the Rn-emanation coefficient (alpha= 0.05-0.2), the emanating rock thickness (X=10 cm) and U-concentration averages 30 ppm. Under wet and non-ventilated conditions the model calculated Rn-gas concentrations (159-1248 pCi/1) are consistent with the measured values by active techniques (231-1348 pCi/1) and by SSNTD techniques (144-999pCi/1), when the Rn-emanation coefficient (alpha=0.1-0.25), the ground water flow (F=0.04-0.10 ml/s-1cm-2) and U-concertrations (100-250ppm)

  5. Bio leaching of Uranium - bearing material from Abu Thor area, West Central Sinai, Egypt for recovering uranium

    International Nuclear Information System (INIS)

    A uranium-bearing material was recorded within the Intra-Carboniferous Paleokarst Profile of Um-Bogma Formation at Abu Thor area, West Central Sinai, Egypt. The present paper is concerned with the bio leaching of U and Cu using Aspergillus Niger (A. Niger) followed their proper recovery. The working Abu Thor representative sample assays 0.22% U as the element of interest as well as up to 25% CuO beside the other rock constituents SiO2 (33%), Al2O3 (10.4%) and CaO(8.5%). The effective bio leaching of U and Cu from Abu Thor ore sample using A.Niger was performed at the following optimum conditions: an incubation time of 6 days, sample/ liquid (S/L) ratio of 1/10, ph value of 1 and a temperature of 60 degree C. The prepared bio leach liquor assays 0.19 g/l of U and 15.8 g/l of Cu with leaching efficiencies of 97% and 79%, respectively. Uranium was recovered using 25% TBP in kerosene at O/A ratio of 1/1 and contact time of 5 min with achieved extraction efficiency of 96%. However the stripping of U was conducted by using 8% Na2CO3 at A/O ratio of 1/1 and contact time of 5 min with stripping efficiency reached 99%. On the other hand, Cu was directly precipitated as CuS using the freshly released H2S gas with the addition of solid Na2S. The optimum precipitation conditions were S/L ratio of 1/100, ph 1.5 and room temperature where the precipitation efficiency of Cu achieved 99%

  6. Extraction of uranium and copper from sulphate leach liquors of West Central Sinai uraniferrous siltstone of Egypt

    International Nuclear Information System (INIS)

    Extraction of uranium and copper from sulphate leach liquors of west central Sinai ore samples were performed using solvent extraction technique. Sulphate leach solutions were processed for the extraction of copper using 3% v/v LIX 973N. Copper extractions higher than 98.1% were obtained. Then, uranium was extracted using a tertiary amine. Two amines have been studied 2% v/v tri-n-octyl amine and 1.5% Alamine 336. Parameters studied included solvents concentration, contact time and solution pH. Stripping of uranium and copper were studied using sodium carbonate and sulphuric acid, respectively. Conditions were established for determining the number of stages required for extraction and stripping of copper and uranium through the construction of the corresponding McCabe-Theile diagrams. The results obtained have been utilized to formulate a proposed flowsheet for the production of uranium and copper from west central Sinai ore samples. (author)

  7. REE Provenance and U-Th Distribution on Poly-Mineralized Lithofacies, Um Bogma Formation, Allouga environs, West Central Sinai, Egypt

    International Nuclear Information System (INIS)

    The Allouga environs, West Central Sinai, are bounded by lat. 28 degree 58/ - 29 degree 03/ N and long. 33 degree 21/ and 33 degree 26/ E, covering about 100 km2. The environs are covered by late Proterozoic basement rocks overlain non conformably by Paleozoic rock succession. The Paleozoic succession attains about 450 m, comprising seven stratigraphic formations. The Um Bogma Formation, Also referred to as the middle carbonate series, attains 61 m thickness and hosts most of the polymetallic mineralization associated with Paleozoic rocks. It was deposited in shallow, warm, well agitated and oxidized transgressed marine environment. Owing to its importance, it is classified into three members: a) lower members comprising siltstone, clay stone and sandy dolomite; b) middle member comprising marly dolostone and c) upper member comprising sandy dolostone, clay stone and siltstone. The REE and trace elements investigations of the shale/siltstone/clay stone lithofacies (Um Bogma Formation), indicate that it mainly comprises graywacke provenance with small amount of litharenites. Also, the data indicates the derivation of the terrigenous material from granite-gneiss and siliceous sources characteristics of sedimentary basins developed near or around active continental margin. The Cu- mineralization occurs in all members of Umm Bog ma Formation as disseminations and encrustation of green and blue colored Cu-minerals dominated by highly oxidized minerals such as silicates, carbonates, phosphates, sulphates and chlorides. This mineral assemblage reflects the wide range of ph conditions of the mineralizing fluids. The U-Th distribution in the shale/siltstone/clay stone lithofaciesis as follows: The marly shales have U content average (261 ppm) and Th content average (7.7 ppm), black and variegated shales have U content average (56.2 ppm) and Th content average (20 ppm), The ferrgenous siltstone have U content average (38 ppm) and Th content average (17.8 ppm), the black

  11. Mineralogy and Radioactivity of Some Pegmatite Bodies, Southeastern Sinai, Egypt

    International Nuclear Information System (INIS)

    The area under consideration constitutes the extreme eastern part of the Kid metamorphic belt in Sinai Peninsula. The Neoproterozoic rock units exposed there comprise gneisses, migmatites, old granitoids and monzogranites. Most of the pegmatite bodies encountered in the monzogranite rocks occur as plug-like bodies and veins of variable dimensions. These studied pegmatites are mainly of the simple unzoned type. They are composed of intergrowths of smoky quartz and pink K-feldspar with some accumulations of micas which host most of radioactive mineralizations. Radiomertrically, the concentration of eU ranges between 41 and 117ppm with an average of 73ppm, while eTh varies between 160 and 433ppm with an average of 223ppm. The Ra content reaches up to 94ppm with an average of 62ppm. The radioelements variation diagrams illustrate that the distribution of radioelements is due to both magmatic origin and hydrothermal redistribution. The high level of radioactivity in the studied granitic pegmatites is mainly resulted from the presence of ishikawaite, thorite, uranothorite, thorianite, zircon, fiptafite and fluorite. Most of the studied radioactive minerals commonly occur in the metamict state. Other accessory minerals like anatase, hematite and magnetite are also recorded. The study reports for the first time the presence of Ishikawaite-Th, where Th prevails U. Ishikawaite-Th grains contain exsolution intergrowths of ishikawaite-U and thorianite.

    2013-03-01

    The concept of ecological succession has been frequently applied in the study of ancient reefs. Whereas Paleozoic and Mesozoic reefs are commonly thought to reveal an autogenic primary—climax zonation, patterns in Neogene and Quaternary reefs are much more diverse. Here, we describe a well-preserved late Pleistocene coral reef from Dahab on Sinai Peninsula (Egypt), which shows a distinct zonation that resembles an ecological succession. In contrast to classical examples of ecological successions, species composition, paleoenvironmental conditions, and coral biodiversity of the Dahab reef indicate an allogenic, sea-level controlled community change, from marginal marine to reef slope and back reef. A review of the literature confirms that autogenic, short-term successions are virtually absent in Quaternary reefs. We predict that long generation times of corals make it unlikely that classical autogenic successions develop in reefs at all, unless environmental conditions are unusually stable.

    Dahab was a little Bedouin-village in Sinai Peninsula at the mid-western coast of Gulf of Aqaba approx. 90 km north of Sharm-el-Sheikh City and it means "gold" in Arabic language. But in the past 20 years ago it becomes one of the most tourist sites in Egypt. The basement complex is composed mostly of biotiteaplite-granite, mica-aplitegranite, granodiorite, quartzdiorite, alaskite, and diorite. Based on correlation with similar igneous in the most southern part of Sinai and the Red Sea area. Wadi Dahab composed of igneous and metamorphic rocks and the coastline is formed of the fragments of its rocks, mixed with fragments of coral reef and fluvial deposits of Wadi Dahab. The morphology of Dahab coastline is characterized by hooked marine spit, which composed of fluvial sediments carried by marine current from wadi Dahab mouth, this spit encloses shallow lagoon, but the active deposition on the lagoon bottom will evaluate it into saline marsh. This paper dealing with the evolution of Dahab spit and lagoon during the Holocene in addition to the recent time for last 100 years, and it impacts of the future management of the coast area. The coastline mapping during the period of study depends upon GIS technique for data were collected during field measuring by using total station, aerial photo and satellite image interpretation as well as soil sample dating. Suggested geomorphological evolution of Dahab area during the Holocene depending upon geomorphic investigation of the sedimentological process into 6 stages.

    Full Text Available The geothermal potentiality in Egypt has a minor significance in the aspects of the Egyptians life, while the hydraulic and hydrocarbonresources are more convenient. However, some other applications for the geothermal activity such as direct warming, pools, and physiotherapy make the research for geothermal as requested. In the present work, two locations with rather good geothermal potentiality will be studied; these are HammamFaraun and Abu Swiera (water temperature is about 70 °C; at Sinai Peninsula.
    The contribution of the geophysical techniques to evaluate such potentiality could be considered, as its capability to identifythe reservoir characteristics and its implementation is acceptable. Therefore, a geophysical survey program has been conductedin terms of seventeen vertical electrical soundings (VES and two wide profiles of Control Source Electromagnetic (CSEM forward step at HammamFaraun and two wide profiles of CSEM at Abu Swiera. The geophysical techniques yield information on the spatial distribution of electrical conductivity, which is the most sensitive parameter to fluids in the rocks. 
    The analysis of the geophysical data, together with the field and geochemical studies lead to the conclusion that, the thermalwater in the subsurface formations might be considered as the preferred cause of the high conductivity in the subsurface on/close to the boarder of tectonically active regions, particularly, where the anomalous conductivity is correlated with high heat flow and other geophysical and geological parameters.

    Full Text Available Site selection analysis was carried out to find the best suitable lands for development activities in an example of promising coastal plains, southwestern Sinai, Egypt. Two GIS models were developed to represent two scenarios of land use suitability in the study area using GIS Multi Criteria Analysis Modeling. The factors contributed in the analysis are the Topography, Land cover, Existing Land use, Flash flood index, Drainage lines and Water points. The first scenario was to classify the area according to various gradual ranges of suitability. According to this scenario, the area is classified into five classes of suitability. The percentage of suitability values are 51.16, 6.13, 22.32, 18.49 and 1.89% for unsuitable, least suitable, low suitable, suitable and high suitable, respectively. The second scenario is developed for a particular kind of land use planning; tourism and recreation projects. The suitability map of this scenario was classified into five values. Unsuitable areas represent 51.18% of the study area, least suitable 16.67%, low suitable 22.85%, suitable 8.61%, and high suitable 0.68%. The best area for locating development projects is the area surrounding El-Tor City and close to the coast. This area could be an urban extension of El-Tor City with more economical and environmental management.

    A longitudinal entomological survey for sandflies was conducted from 1989 to 1991 at a focus of enzootic cutaneous leishmaniasis in Northeast Sinai, Egypt, within the border region monitored by multinational peacekeepers. Standardized sampling with CDC light traps, oiled paper "sticky traps", and human landing collection was employed to determine monthly trends in species composition, density, sex ratio, and reproductive status of vector sandflies. Each collection method independently defined sandfly seasonality as the period May-November in 1990, and March-October in 1991. Plebotomus papatasi was the only anthropophagic species found and comprised more than 94% of the sandfly population. Two population peaks (May, July) were observed for this species in both survey years. Density of P. papatasi in underground bunkers was higher than outside but inflated by a greater proportion of male flies. During 1990, the proportion of gravid P. papatasi increased progressively during the 5 months period from May to September and averaged 29.5% and 29.7% for interior and exterior collections, respectively. Density of P. papatasi was greater during 1991, but proportions of gravid flies were significantly lower in each survey month and averaged 14.9% and 12.3% for interior and exterior collections, respectively. Seasonal rates of Leishmania-infected P. papatasi averaged 0.8% and 0.9% in 1989 and 1990, but fell to zero in 1991, suggesting an unstable focus of Leishmania major transmission. Proportions of gravid flies may be a valid indicator of the physiological age and epidemiologic importance of the vector sandfly population at this focus. The strong correlation of sticky trap indices to human-landing/biting rates shows that this is an accurate, inexpensive, and no-risk alternative to human bait collections. PMID:17270138

  2. Appraisal Of Groundwater In El-Tur Area, Southwest Sinai, Egypt

    International Nuclear Information System (INIS)

    The Quaternary aquifer represents the main source of water supply in El-Tur area, southwest Sinai, Egypt. The groundwater quantity and quality of the aquifer as well as factors affecting them were studied using multidisciplinary techniques including hydrogeological, hydrochemical and isotopic investigations. Groundwater of the Quaternary aquifer is of meteoric origin, mainly recharged from the continental and Mediterranean precipitations. The aquifer is essentially recharged by occasional processes of short and long period surface runoffs as well as the subsurface outflow from the fractured Pre-Cambrian basement aquifer. The aquifer exists under unconfined conditions. The water table is recorded at levels 26 m (MSL) and 4 m (MSL) with a hydraulic gradient of about 0.00139 averagely. The groundwater has a flow trend from the northeast to southwest. The annual inflow rate through the aquifer was estimated to be 6.7 million m3. Groundwater has an alkaline character with salinity ranging from 374.4 mg/l (fresh water) to 7396.5 mg/l (more saline water). The salinity and major ions were increased in the direction of groundwater flow, except for the bicarbonate one. Significant positive relationships were investigated between TDS and major ions. The groundwater is classified into three chemical zones, the carbonate, sulphate and chloride zones. Four genetic types of water (HC3-Na, SO4-Na, Cl-Mg and Cl-Ca) were identified, reflecting the prevailed environmental conditions upon the studied aquifer. The groundwater is assessed for different uses where those of the carbonate and sulphate zones are suitable for irrigation, drinking and domestic uses and most of the chloride zone are not suitable. Origin and geochemical evolution of the groundwater of the Quaternary aquifer in El-Tur area are investigated as based on the facies of the water bearing rocks, the hydrochemical characteristics and the functions of environmental isotopes.

    2011-05-01

    Systematic planning for groundwater exploration using modern techniques is essential for the proper utilization, protection and management of this vital resource. Enhanced Thematic Mapper Plus (ETM+) images, a geographic information system (GIS), a watershed modeling system (WMS) and weighted spatial probability modeling (WSPM) were integrated to identify the groundwater potential areas in the Sinai Peninsula, Egypt. Eight pertinent thematic layers were built in a GIS and assigned appropriate rankings. Layers considered were: rainfall, net groundwater recharge, lithology or infiltration, lineament density, slope, drainage density, depth to groundwater, and water quality. All these themes were assigned weights according to their relative importance to groundwater potentiality and their corresponding normalized weights were obtained based on their effectiveness factors. The groundwater potentiality map was finally produced by WSPM. This map comprises five gradational groundwater potentiality classes ranging from very high to very low. The validity of this unbiased GIS-based model was tested by correlating its results with the published hydrogeological map of Egypt and the actual borehole yields, where a concordant justification was reached. The map declared that the Sinai Peninsula is generally of moderate groundwater potentiality, where this class encompasses an area of 33,120 km2 which represents 52% of its total area.

  4. Successive Recovery of Copper and Uranium From Carbonate-Rich Latosol, Um Bogma Formation, Abuthor Locality, South Western Sinai, Egypt

    International Nuclear Information System (INIS)

    A technological sample of a copper/ uranium mineralization in carbonate rich latosol rock sequence of Urn Bogma Formation Abu Thor locality at southwestern Sinai, Egypt, has been properly processed. The working sample assaying 12.5 % CuO and 875 ppm U was subjected to adipic acid leaching for copper followed by bioleaching of uranium in a manner to avoid excessive acid consumption in the classical leaching procedure. It is thus possible to achieve leaching efficiencies of 95% for Cu in the first stage and 82% for U in the second stage. From the two separately obtained leach liquors of Cu and uranium, pure products have conveniently been prepared. Accordingly, Cu adipate product was first prepared by crystallization,followed by acid dissolution and alkali precipitation of copper hydroxide. In case of uranium, the impure precipitate of the bioleach liquor is purified via Amberlite IRA-400 anion exchanger resin

    Full Text Available Aim: To monitor the effect of nutrition and pregnancy on oxidative status of animals under the arid condition of South Sinai. Materials and Methods: Blood samples were taken from two groups of animals: The first group retained in farm and fed on concentrate (high diet and another group grazing natural forage (low diet. Each group was subdivided into pregnant and non-pregnant animals. Blood samples were assayed for their content of malondialdehyde (MDA, total antioxidant capacity (TAC, catalase (CAT, and superoxide dismutase (SOD enzymes. Results: MDA level significantly increased in pregnant animals fed either concentrate or grazing low-quality forage and accompanied by a low level of TAC in pregnant grazing animals fed low-quality forage. The activity of CAT decreased in pregnant fed either concentrate or grazing and SOD significant decrease in the pregnant grazing group. These data suggested that the animals might have experienced some degree of oxidative stress and lipid peroxidation and indicating that redox homeostasis was impaired in those pregnant and specially fed on forage rations. Conclusion: Pregnancy constituted the most oxidative stress facing the grazing and concentrated diet feed sheep and goats under arid and saline conditions of Southern Sinai, Egypt.

    International Nuclear Information System (INIS)

    Radon gas and radon daughters concentrations were measured by active techniques using two instruments: EDA( RDA-200) and Tri-Met-372. The measurements were carried out during the month of June in a tunnel network at Allouga area, west central Sinai. In the ventilated sector (16 stations), the average tunnel air temperature was 24.4 ± 2.2 degree c and average relative humidity 38%. The radon gas concentrations using calibrated Lucas cell ranged 3.3-22.8 pCi/1 with an average of 11.9 pCi/1. The radon daughters concentration using Tri-Met-372: Kusnetz method range 0.01 -0.36 Wl and average 0.1 WL and Modified Tsivoglou method range 0.01-0.38 WL and average 0.1 WL. The results of the EDA(RDA-200) are :Rolle method range 0.01-0.29 WL and average 0.13 WL, Kusnetz method range 0.01-0.31 WL and average 0.12 WL, and Tsivoglou method range 0.02-0.41 Wl and average 0.15 WL. These reported averages estimated by the different techniques are consistent within the statistical errors. In the non-ventilated sector (12 stations), the average tunnel air temperature was 22.2±0.4 degree and average relative humidity 70%. The radon gas concentrations range 313-1348 pCi/1 and average 786 pCi/1. The radon daughters concentrations using Tri-Met-372 :Kusnetz method range 1.4 -13.88 WL and average 7.21 WL. The results of the EDA (RDA-200) are : Rolle method range 1.04- 12.9 Wl and average 6.910 WL. Kusnetz method range 0.98 - 12.24 WL and average 6.92 WL, and Tsivoglou method range 0.92-12.09 WL and average 6.84 WL. The reported averages by the different methods are consistent within the statistical errors. It is clear that the non-ventilated sector presents occupational working hazard in these tunnels, and strict radiation protection measures should be undertaken such as industrial ventilation

    Full Text Available Phlomis aurea Decne is a rare and endangered species inhabiting high altitudes at southern Sinai Peninsula, Egypt. The present study investigated the population structure of P. aurea, in terms of size distribution, height, diameter, density, frequency and cover at its favourable habitats, and attempted to assess the effect of different habitats, which reflect the elevation gradients, on sizes distribution and density of occurrences of the study species. Sixty five stands (each of 25 × 25 m were sampled to represent most variations among P. aurea populations in four main habitats (basins, mountain slopes, gorges and wadi beds. P. aurea in basins had the highest plant frequency, cover, plant diameter and height, size index, leaf length and width, leaves, branches, flowers, inflorescences and inflorescence length, while slope population had the lowest. Population in gorges and wadi beds had the highest height to diameter ratio, while in basin and slope had the lowest. Plants in gorges had the highest density, followed by those in basins, wadi beds and slopes. The size structures in the gorges and basins approximated the normal distribution; while that of the slope population approximated the positively skewed distribution. The plant cover was positively correlated with silt, clay, Ca, altitude, CaCO3, fine sand and HCO3; while it was negatively correlated with soil pH and Mg. In addition, plant cover response along soil salinity (EC gradient approximated normal distribution. This study may help in planning for conserving this endemic species and we recommend, as a priority, to increase the area of the protected areas at mid- to high altitude in the Southern Sinai to grant further protection in zones with the highest density of endemics.

  9. Environmental Radiation Studies in Mn-Mines at Wadi Naseib Area, South West Sinai, Egypt

    International Nuclear Information System (INIS)

    The activity concentrations of radon and thoron decay products beside the gamma dose rate of the naturally occurring radionuclides were measured and calculated in two underground manganese mines, M1 and M2 at Wadi Naseib area in Sinai. Radon daughters and thoron daughters working levels were calculated using Rolle method after measuring the alpha activity. The measurements were taken at different stations inside the two mines. The radiation levels were calculated at seven stations inside the first mine and at ten stations inside the second mine. It was found that, the radon daughter products have major effect while the thoron daughter products and -dose have the minor effect in U/G mines. These measurements will be considered in perspective with the ventilation required to lower the radon decay products inside the mine in order to establish adequate working level that conform with proper radiation safety requirements for workers inside these mines

    North Sinai deserts were surveyed for the predominant plant cover and for the culturable bacteria nesting their roots and shoots. Among 43 plant species reported, 13 are perennial (e.g. Fagonia spp., Pancratium spp.) and 30 annuals (e.g. Bromus spp., Erodium spp.). Eleven species possessed rhizo-sheath, e.g. Cyperus capitatus, Panicum turgidum and Trisetaria koelerioides. Microbiological analyses demonstrated: the great diversity and richness of associated culturable bacteria, in particular nitrogen-fixing bacteria (diazotrophs); the majority of bacterial residents were of true and/or putative diazotrophic nature; the bacterial populations followed an increasing density gradient towards the root surfaces; sizeable populations were able to reside inside the root (endorhizosphere) and shoot (endophyllosphere) tissues. Three hundred bacterial isolates were secured from studied spheres. The majority of nitrogen-fixing bacilli isolates belonged to Bacillus megaterium, Bacillus pumilus, Bacillus polymexa, Bacillus macerans, Bacillus circulans and Bacillus licheniformis. The family Enterobacteriaceae represented by Enterobacter agglomerans, Enterobacter sackazakii, Enterobacter cloacae, Serratia adorifera, Serratia liquefaciens and Klebsiella oxytoca. The non-Enterobacteriaceae population was rich in Pantoae spp., Agrobacterium rdiobacter, Pseudomonas vesicularis, Pseudomonas putida, Stenotrophomonas maltophilia, Ochrobactrum anthropi, Sphingomonas paucimobilis and Chrysemonas luteola. Gluconacetobacter diazotrophicus were reported inside root and shoot tissues of a number of tested plants. The dense bacterial populations reported speak well to the very possible significant role played by the endophytic bacterial populations in the survival, in respect of nutrition and health, of existing plants. Such groups of diazotrophs are good candidates, as bio-preparates, to support the growth of future field crops grown in deserts of north Sinai and irrigated by the water of El

  12. Effect of mineral constituents in the bioleaching of uranium from uraniferous sedimentary rock samples, Southwestern Sinai, Egypt

    International Nuclear Information System (INIS)

    Bioleaching, like Biotechnology uses microorganisms to extract metals from their ore materials, whereas microbial activity has an appreciable effect on the dissolution of toxic metals and radionuclides. Bioleaching of uranium was carried out with isolated fungi from uraniferous sedimentary rocks from Southwestern Sinai, Egypt. Eight fungal species were isolated from different grades of uraniferous samples. The bio-dissolution experiments showed that Aspergillus niger and Aspergillus terreus exhibited the highest leaching efficiencies of uranium from the studied samples. Through monitoring the bio-dissolution process, the uranium grade and mineralogic constituents of the ore material proved to play an important role in the bioleaching process. The tested samples asserted that the optimum conditions of uranium leaching are: 7 days incubation time, 3% pulp density, 30 °C incubation temperature and pH 3. Both fungi produced the organic acids, namely; oxalic, acetic, citric, formic, malonic, galic and ascorbic in the culture filtrate, indicating an important role in the bioleaching processes. - Highlights: • Aspergillus niger and Aspergillus terreus are the only isolates achieved highest leaching efficiency of uranium from the studied samples. • Bioleaching process directly related to variations in mineral constituents and uranium grades. • The optimum conditions of uranium bioleaching from its ores, were found to be 7 days, 3% pulp density, pH 3 and 30 °C. • A. niger and A. terreus organic acids play an important and effective role for uranium leaching process

  13. Potential Egypt-Israel joint venture to establish a solar equipment manufacturing and energy center at El Arish on Sinai

    International Nuclear Information System (INIS)

    This presentation is a proposal made in the context of the evolving plans for power system interconnection in the Mashreq Arab countries of the Middle East, including studies completed for the Gulf States Interconnection along the Arabian Gulf from Kuwait to Oman. It also introduces the possibility of eventual interconnection of these systems with a major HVDC interconnection between the Inga hydropower source in Zaire and Egypt via an energy exchange center located at El Arish on Sinai. As realization of the Inga hydropower development will require many years to accomplish and as current plans for interconnection in the Mashreq Arab countries are proceeding, it is thought that introduction of the possibility for eventual inter-regional interconnection between Africa and the Middle East should be considered within a time-frame that would encompass a dual-purpose aim beginning with the establishment of a solar equipment manufacturing facility to accentuate solar energy conversion for desalination and hydrogen production within the region. If this facility were located in convenient proximity to major nodes of the interconnected systems of the region, then it ultimately would be both a solar equipment manufacturing and energy exchange (SEMEX) center

  14. Leaching Characteristics of Uranium and Vanadium From Wadi El-Sahu Carnotite- Bearing Kaolin, South Western Sinai, Egypt

    International Nuclear Information System (INIS)

    The leaching roats of carnotite-bearing kaolin sample from the lower carboneferous Um Bogma formation at Wadi El-Sahu, south western Sinai, Egypt, contain 2.6% U3O8 and 1.2% V2O5 , have been studied. Both sulfuric acid agitation and pug leaching techniques were applied. From the obtained agitation results, it was concluded that both acid concentration and temperature were quite important for increasing the leaching efficiency of the two studied metal values; about 82.5 and 50.5 % for U and V, respectively. The optimum conditions were 200 g/l H2SO4 at 50 degree C for 2 h agitation time in a solid / liquid ratio of 1/5. the results showed that high temperature and concentrated acid were required and the applied optimum pug leaching conditions of mesh size < 200 with an ore / acid ratio of 1/1 at 300 degree C for 4 h have resulted in about 81 and 87% of U and V leaching efficiencies, respectively.

    Large NE-SW oriented asymmetric inversion anticlines bounded on their southeastern sides by reverse faults affect the exposed Mesozoic and Cenozoic sedimentary rocks of the Maghara area (northern Sinai). Seismic data indicate an earlier Jurassic rifting phase and surface structures indicate Late Cretaceous-Early Tertiary inversion phase. The geometry of the early extensional fault system clearly affected the sense of slip of the inverted faults and the geometry of the inversion anticlines. Rift-parallel fault segments were reactivated by reverse slip whereas rift-oblique fault segments were reactivated as oblique-slip faults or lateral/oblique ramps. New syn-inversion faults include two short conjugate strike-slip sets dissecting the forelimbs of inversion anticlines and the inverted faults as well as a set of transverse normal faults dissecting the backlimbs. Small anticline-syncline fold pairs ornamenting the steep flanks of the inversion anticlines are located at the transfer zones between en echelon segments of the inverted faults.

  16. Evaluating the Rate of Stone Art Deterioration in Wadi Maghara and Wadi Mukattab, Sinai, Egypt

    2012-06-01

    Full Text Available One of the key reasons for the status of Wadi Maghara and Wadi Mukattab as World Heritage Sites is the abundance of stone art present there. Unfortunately, in time, much of the stone art heritage in the two archaeological sites was lost, due to natural stone weathering processes, to static and dynamic actions and lately, due to the lack of preservation measures and to the action of people. That fragile art heritage is non-renewable and, therefore, it requires specialized management. Several stone facades in Wadi Maghara have embossed inscriptions of early rulers of Egypt, that document their expeditions to mine precious minerals, primarily turquoise and copper, that were found in the area. Wadi Mukattab (south of Wadi Maghara is the valley of inscriptions. Over a distance of 3 km along this valley inscriptions can be found on the mountain rocks that have mostly been made by Nabateans (2nd and 3rd Century but also by others, such as pilgrims, soldiers, merchants, throughout the centuries. In our case study, inscriptions from specific study areas were analyzed by using SEM, polarizing microscope, XRD, SEM with EDX, DTA-TGA, Grain Size Distribution, Pore Media Characterization and some stone samples were tested in the stone mechanics laboratory, to determine the physical and mechanical characteristics of the stone with carved inscriptions. Digital photographs were taken, with Geographic Information Systems software. Older images were compared with more recent ones and in order to classify and quantify the amount of deterioration that occurred over time. Various methodologies were applied to classify the images, and it was found that manual digitizing provided the best means for quantifying the amount of deterioration. Results showed that the damage was primarily caused due to the instability of stone structures, because of the extensive jointing and rock fall gravity, due to dynamic actions and the granular disaggregation of the stone surface.

    Full Text Available 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 the wadi deposits based on grain size distribution and predominant rock composition as this information may lead to the location of new groundwater resources. An unsupervised classification was first performed on two sets of fused images (i.e., ETM+/Radarsat-1 and ETM+/PALSAR resulting in five classes (hybrid classes describing the main alluvial sediments in the wadi system. Some variations in the spatial distribution of individual classes were observed, due to the different spectral and spatial resolutions of Radarsat-1 (C-band, 12.5 m and PALSAR (L-band, 6.25 m data. Alluvial deposits are mixtures of parent rocks located further upstream often at a great distance. In order to classify the alluvial deposits in terms of individual rock types (endmembers, a spectral linear unmixing of the optical ETM+ image was performed. Subsequently, each class of the fused (hybrid images was correlated with (1 individual rock type fractions (endmembers obtained from spectrally unmixing the ETM+ image, (2 the geocoded and calibrated radar images (Radarsat-1 and PALSAR and, (3 the slope map generated from the SRTM data. The goal was to determine predominant rock composition, mean backscatter and slope values for each of the five hybrid classes. Backscatter coefficient values extracted from both radar data (C- and L-band were correlated and checked in the field, confirming that both wavelengths produced more or less similar textural classes that correspond to specific grain or fragment sizes of alluvial deposits. However, comparison of the spatial distribution of matching

    2015-11-01

    This study discusses the mechanism of dolomitization of carbonate rocks of the Upper Turonian Wata Formation in west Sinai, Egypt. It has been done in terms of study of textural, mineralogical, and geochemical characteristics of the dolostones and dolomitic limestones of the Wata Formation. The Wata Formation is composed mainly of dolostone and dolomitic limestone intercalated with few shale and sandstone beds. Beside the studied dolostone facies, five associated limestone microfacies have been identified. The limestone microfacies also provide an evidence of sparse dolomitization. Dolomites occur as replacive dolomites with minor dolomite cements. Four textural types of dolomite are distinguished: (1) fine-crystalline, planar-s (subhedral, hypidiotopic) replacive dolomite; (2) medium-to coarse-crystalline, planar-e (euhedral, idiotopic) replacive dolomite; (3) medium-crystalline, planar-s (subhedral, hypidiotopic) replacive dolomite, and (4) fine-crystalline, planar-e (euhedral, idiotopic) void-filling dolomite cements. The recorded dolomite is nearly non-stoichiometric (CaCO3 ranges from 51 to 56 mol % with an average of 53.5 mol %) and has similar geochemical features. It has δ18OVPDB values range from -7.16‰ to +0.26‰ and δ13C VPDB values vary between -0.52‰ and +5.2‰. Its strontium content lies between 11 and 53 ppm. Petrographic investigations and geochemical data indicated that the dolomitization of the studied carbonates probably took place in a meteoric water-sea water mixing zone at shallow burial depth during the early stage of diagenesis. In this situation, the dolomitization was developed through an increase of Mg/Ca ratio of the pore water, with no salinity increase. The increase of Mg/Ca ratio took place by two possible ways: (1) through leaching of Mg from high Mg-calcite grains (micrite) and aragonitic shells in the studied limestone (2) through leaching of Mg adsorbed on clays of the adjacent mudrock horizons. Such leaching brought about

    International Nuclear Information System (INIS)

    Measurements of Rn-gas concentrations and Working Level (WL), were carried out in the U-exploration galleries at El- Allouga Mine, Sinai, Egypt by passive techniques (SSNTD) during the four seasons ( Summer, Fall, Winter and Spring) using four different detector types: CR-39, MK, CN-85 and LR-115.Twenty eight (28) stations were chosen for this purpose reflecting different environmental conditions as measurement sites within the galleries. The Rn-gas concentrations , in the summer period ranged from 25.86 to 44.2 pCi/l in the ventilated stations and from 488.98 to 611.16 pCi/l in the non-ventilated stations. In the fall period , the average Rn-gas concentrations in the ventilated stations ranged from 31.61 to 56.36 pCi/l while in the non-ventilated stations from 457.61 to 621.52 pCi/l. In the winter period, the average Rn-gas concentrations in the ventilated stations ranged from 27.59 to 66.45 pCi/l while in the non- ventilated stations from 499.09 to 603.81 pCi/l. In the spring the Rn-gas concentrations ranged from 30.8 to 46.77 pCi/l in the ventilated stations, whereas, in the non-ventilated stations from 404.06 to 445.18 pCi/l. The (WL), in the summer period, ranged from 0.143 to 0.247 in the ventilated sector and from 4.408 to 5.497 in the non-ventilated stations .In fall, the( WL) ranged from 0.166 to 0.295 in the ventilated stations and from 4.123 to 5.624 in the non-ventilated stations. In the winter, the (WL) ranged from 0.105 to 0.37 in the ventilated stations and from 4.138 to 5.26 in the non-ventilated stations. In the spring, the (WL) in the ventilated stations ranged from 0.152 to 0.241 and from 3.696 to 4.087 in the non-ventilated stations. These results indicate that: i)The low measured Rn gas and (WL) values in the ventilated stations reflect the effect of variations in meteorological conditions on (WL) determination where the air flow carries the Rn-gas before it decays and the daughters are plated onto the SSNTD . ii) The larger ranges for Rn

  20. Comparison Between Active and Passive Techniques for Radon Gas and Working Level measurements, El-Allouga Mine, Sinai, Egypt

    International Nuclear Information System (INIS)

    Two different techniques were used for measuring Rn-gas concentrations and Working Level (WL) in U-exploration galleries at El-Allouga Mine, Sinai, Egypt. The active techniques used EDA(RDA-200) with calibrated Lucas cell and Tri-Met-372 instruments and passive techniques used four different types of SSNTD. Twenty eight (28) stations inside the studied tunnels were located covering the different environmental conditions. The measurements were carried out during summer time, in the ventilated sector (16 stations), the average tunnel air temperature was 24.4 ± 2.2 degree C and relative humidity 38%. In the non-ventilated sector (12 stations), the average tunnel air temperature was 22.2±0.4 degree C and relative humidity 70%. The Rn-gas concentrations using EDA(RDA-200) and calibrated Lucas cell, in the ventilated sector averaged 11.966 p Ci/l, while in the non-ventilated stations averaged 786.21 p Ci/l. Also for the Tisvoglu method, the values of (WL) in the ventilated stations averaged 0.149, while in the non-ventilated stations averaged 6.838. For Kusentz method, the (WL) in the ventilated stations averaged 0.1163, while in the non-ventilated stations averaged 6.918. For Rolle method, in the ventilated stations the (WL) averaged 0.1318, while in the non-ventilated stations averaged 6.914. In case of the Tri-Met-372 instrument, for the modified Tisvoglu method, the ( WL) in the ventilated stations averaged 0.098, while in the non-ventilated stations averaged 7.161. For the Kusentz method, the (WL) in the ventilated stations averaged 0.0985, while in the non-ventilated stations averaged 7.241. The data obtained by SSNTD (Passive Techniques) using CR-39, MK, CN-85 and LR-115 detectors showed that the averages of Rn-gas concentrations ranged from 25.86 to 44.20 p Ci/l in the ventilated stations and from 488.98-514.72 p Ci/l in the non-ventilated stations. The average of calculated (WL) ranged from 0.144 - 0.247 in the ventilated stations and from 4.408 to 5.497 in

    Identifying a good site for groundwater exploitation in hard-rock terrains is a challenging task. In Sinai, Egypt, groundwater is the only source of water for local inhabitants. Interpretation of satellite data for delineation of lithological units and weathered zones, and for mapping of lineament density and their trends, provides a valuable aid for the location of groundwater promising areas. Complex deformational histories of the wide range of lithological formations add to the difficulty. Groundwater prospect mapping is a systematic approach that considers the major controlling factors which influence the aquifer and quality of groundwater. The presented study aims to delineate, identify, model and map groundwater potential zones in arid South Sinai using remote sensing data and a geographic information system (GIS) to prepare various hydromorphogeological thematic maps such as maps of slope, drainage density, lithology, landforms, structural lineaments, rainfall intensity and plan curvature. The controlling-factor thematic maps are each allocated a fixed score and weight, computed by using a linear equation approach. Furthermore, each weighted thematic map is statistically computed to yield a groundwater potential zone map of the study area. The groundwater potential zones thus obtained were divided into five categories (very poor, poor, moderate, good and very good) and were validated using the relation between the zone and the spatial distribution of productive wells and of previous geophysical investigations from a literature review. The results show the groundwater potential zones in the study area, and create awareness for better planning and management of groundwater resources.

    To better understand the epidemiology of diarrhea in deployed personnel to the Middle East, a prospective cohort study of travelers' diarrhea (TD) was conducted between May 2004 and January 2005 at the Multinational Force and Observers (MFO) camp in the southern Sinai. A baseline entry questionnaire and stool specimen was provided on study entry, and volunteers were followed every 6 weeks. Of 211 volunteers, 145 (68.7%) completed one or more follow-up visits. In total, 416 follow-up surveys were completed, which described an overall incidence of 25.2 episodes per 100 person months (95% confidence interval = 21.2–30.0). Additionally, stools were collected in 72 of 77 diarrhea-associated clinic visits, with bacterial pathogens most commonly isolated (enterotoxigenic Escherichia coli in 30 [42%] samples and Campylobacter jejuni in 7 [10%] samples) Despite modern preventive methods, diarrhea is still a common problem for deployed US military personnel in Egypt, frequently resulting in diminished ability to work.

  3. Joint inversion of VES and TEM data for investigation of geothermal resources and sea water intrusion at Hammam Mousa hot spring, Sinai, Egypt

    International Nuclear Information System (INIS)

    Complete text of publication follows. Geoelectrical methods are pioneer in geothermal resources exploration. With the advent of computing technology, it has become convenient to apply sophisticated data analysis and joint inversion to different field data sets. Numerous studies have shown that, the joint interpretation of galvanic and inductive data, where a single model satisfies both data sets, will generally enhance the resolution of the subsurface resistivity structure. Thus, the inclusion of inductive data in the VES data set is expected to reduce problems with layer suppression, reduce the low and high resistivity equivalences that may be encountered with this method. In this work, DC resistivity and transient electromagnetic surveys were conducted at Hammam Mousa area, Sinai, Egypt to explore the geothermal resources, groundwater aquifer and the effect of sea water invasion on this aquifer. The field survey comprises 19 DC resistivity soundings (VESes) with AB/2 up to 1000m and 27 transient electromagnetic (TEM) stations using a square loop of 25 m side length. Both data sets were firstly inverted in 1-D scheme using a nonlinear least-squares method and gave a layered-earth resistivity model. Besides, the joint interpretation of both VES and TEM data, using the available geological information as a constraining factor, could successfully enhance the inversion results. The geoelectrical cross section resulted from the inversion process shows the effect of the Suez Gulf water intrusion in the western part of the study area. Meanwhile, hot water reduces the resistivity values drastically near the hot spring.

    Full Text Available Introduction and Aim of Work: Central nervous system (CNS tumors represent a major public health problem, and their epidemiological data in Egypt have been rather incomplete except for some regional reports. There are no available frequency-based data on CNS tumors in our locality. The objective of this study was to estimate the frequency of CNS tumors in east delta region, Egypt. Materials and Methods: The data were collected during the 8-year period from January 1999 to December 2007 from Pathology Department, Mansoura University, and other referred pathology labs. Examination of HandE stained sections from retrieved paraffin blocks were done in all cases for histopathologic categorization of C.N.S. tumors. Immunohistochemical studies were applied to confirm final histopathologic diagnosis in problematic cases. Results: Intracranial tumors represented 86.7% of cases in comparison to only 13.3% for spinal tumors. Gliomas were the CNS tumors of the highest frequency (35.2%, followed by meningioma (25.6%, pituitary adenoma (11.6% and nerve sheath tumors (6.6%. 10.25% of tumors were of children <15 years. Conclusion: This study provides the largest series of the relative frequency of CNS tumors in Delta region in Egypt till now and may help to give insight into the epidemiology of CNS tumors in our locality.

  5. Physico - chemical Up-grading studies of uraniferous xenotime mineral from ferruginous siltstone sediments of Um hamd, Um bogma area, sinai, Egypt

    International Nuclear Information System (INIS)

    The exposed paleozoic deposits at Um Bogma area in west central sinai contain three main units namely; the lower sandstone, the middle carbonate and the upper sandstone. These units are composed of intercalation of clay minerals, sand, carbonate and iron oxides.The upper layers of the lower sandstone and the base of the middle carbonate units contain possible resources of anomalously uraniferous xenotime (YPO4). Xenotime, being preferentially concentrated with the very fine grain sizes, is more abundant in the argillaceous sediments. The associated clay minerals are represented by kaolinite the non-clay minerals include hematite, goethite and quartz.The up-grading of uraniferous xenotime from a bulk head sample assaying 1.44% Y2O3 was performed by collaborative technological processes that include; liquid/liquid separation using two immiscible liquids (CCI4 and H2O) and finally acid leaching. By applying the proposed flowsheet, more than 90% of xenotime is recovered with an assay value of more than 45% Y2O3. The simplicity of the proposed flowsheet allows it to be adopted to semi-industrial or even industrial purposes

    This paper aims to study the mineralogical composition and determine the petroleum potential of source rocks of the Oligocene-Miocene sequence in the Nile Delta and North Sinai districts. The studied interval in the five wells can be divided into five rock units arranged from the top to base; Qawasim, Sidi Salem, Kareem, Rudeis, and Qantara formations. The bulk rock mineralogy of the samples was investigated using X-Ray Diffraction technique (XRD). The results showed that the sediments of the Nile Delta area are characterized by the abundance of quartz and kaolinite with subordinate amounts of feldspars, calcite, gypsum, dolomite, and muscovite. On the other hand, the data of the bulk rock analysis at the North Sinai wells showed that kaolinite, quartz, feldspar and calcite are the main constituents associated with minor amounts of dolomite, gypsum, mica, zeolite, and ankerite. Based on the organic geochemical investigations (TOC and Rock-Eval pyrolysis analyses), all studied formations in both areas are thermally immature but in the Nile delta area, Qawasim, Sidi Salem and Qantara formations (El-Temsah-2 Well) are organically-rich and have a good petroleum potential (kerogen Type II-oil-prone), while Rudeis Formation is a poor petroleum potential source rock (kerogen Type III-gas-prone). In the North Sinai area, Qantara Formation has a poor petroleum potential (kerogen Type III-gas-prone) and Sidi Salem Formation (Bardawil-1 Well) is a good petroleum potential source rock (kerogen Type II-oil-prone).

    Progress in the past three decades in geophysical data processing and interpretation techniques was particularly focused in the field of aero-geophysics. The present study is to demonstrate the application of some of these techniques, including Analytic Signal, Located Euler Deconvolution, Standard Euler Deconvolution, and 2D inverse modelling, to help in enhancing and interpreting the archeo-magnetic measurements. A high-resolution total magnetic field survey was conducted at the ancient city of Pelusium (name derived from the ancient Pelusiac branch of the Nile, and recently called Tell el-Farama), located in the northwestern corner of the Sinai Peninsula. The historical city had served as a harbour throughout the Egyptian history. Different ruins at the site have been dated back to late Pharaonic, Graeco-Roman, Byzantine, Coptic, and Islamic periods. An area of 10,000 m2, to the west of the famous huge red brick citadel of Pelusium, was surveyed using the magnetic method. The chosen location was recommended by the Egyptian archaeologists, where they suspected the presence of buried foundations of a temple to the gods Zeus and Kasios. The interpretation of the results revealed interesting shallow-buried features, which may represent the Temple's outer walls. These walls are elongated in the same azimuth as the northern wall of the citadel, which supports the hypothesis of a controlling feature such as a former seacoast or shore of a distributary channel.

    The Um Zariq and Malhaq formations occupy roughly the northern half of the Kid metamorphic complex of SE Sinai, in the NE part of the Arabian-Nubian Shield. The Um Zariq Formation metasediments are relicts of an old sedimentary sequence (Cryogenian; 813 ± 6 Ma), whereas the Malhaq Formation records several phases of Ediacaran sedimentation and volcanic activity (615-607 Ma). The Um Zariq Formation is mainly represented by well-bedded metapelitic schists, while the Malhaq Formation comprises a series of structureless to schistose felsic to intermediate metavolcanics interbedded with mica-rich phyllites and schists. The Um Zariq metasediments are depleted in SiO2, CaO and K2O and enriched in TiO2, Al2O3 and K2O relative to those of the Malhaq Formation. Aside from the relatively low Ni and Cr concentrations, compatible transition elements of these metasediments are comparable to average crustal contents. Except for marked Sr depletion, LILEs are around average continental crust values. Pronounced negative Nb-Ta anomalies and enrichment of Um Zariq samples in Th, U, Zr, Ti and Y relative to Malhaq ones are the main features of HFSEs. The REE patterns of all samples are parallel to sub-parallel LREE-enriched, with distinct negative Eu anomalies and weakly fractionated HREE segments. The source rocks of the Malhaq Formation metasediments underwent mild to moderate chemical weathering, whereas those of the Um Zariq Formation have suffered severe chemical weathering. These metasediments are predominately derived from felsic to intermediate igneous sources, with a particular slight addition from recycled sedimentary source to the Malhaq Formation metasediments. They are collectively geochemically immature and have suffered minor sedimentary recycling, with the experience of the Malhaq Formation metasediments from higher degree of sorting and reworking. The Malhaq and Um Zariq metasediments were originally deposited in a continental arc setting, most probably back

    Archaeological and cultural heritage of Egypt is world-known, but its geological heritage is yet to be revealed. Investigations in the central Western Desert of Egypt permitted finding a lot of unique features that can be assigned to this heritage. In the Bahariya Oasis, 10 geological heritage types are established, namely stratigraphical, paleontological, sedimentary, igneous, mineralogical, economical, paleogeographical, geomorphological, hydrological and hydrogeological, and pedological types. In the Farafra Oasis and vicinities, only geomorphological and hydrological and hydrogeological types are found. On the area between these oases, sedimentary, mineralogical, paleogeographical, and geomorphological features are established. Chalk and nummulitic limestones, invertebrate and dinosaur localities, paleoreefs and paleokarst, iron ore deposit, and peculiar landforms occur on the study territory. Taken together, these features constitute a highly diverse geological heritage that can be judged global (even if the rank of individual objects is often relatively low). This heritage is well suitable for the purpose of geotourism; for instance, thematic excursions explaining the geological evolution during the last 100 Ma are possible. Participants of such excursions can also see different facies. A geopark in the central Western Desert of Egypt would facilitate geoconservation and geotourism activities.

  13. Significance of Airborne Gamma-ray spectrometric data of Umm bisilla Area, central Eastern Desert, Egypt

    International Nuclear Information System (INIS)

    Umm bisilla area, located in the Central Eastern Desert of Egypt, consists mainly of basement rocks. The present investigation of the airborne spectrometric data is to define the meaningful anomalies from the raw data by applying the significance factor techniques, by calculating the significant radioactive provinces. Determination of the gross structural pattern and broad variations in composition of the crystalline basement, to define the relationships between the tectonic features of the area as interpreted from aeromagnetic data, with the significant anomalies revealed from spectrometric data was carried out through the application of different magnetic techniques. Five significant uraniferous zones were detected associated with Umm Bisilla granite, amphibolite, and grey granite. The intersection of the structural lineaments interpreted from aeromagnetic data illustrated good correlation with the significant uranium anomalous zones interpreted from spectrometric data, and indicated that the concentration is structurally. 15 figs

    The pegmatite bodies of the Eastern Desert of Egypt are widely distributed especially along the Marsa-Alam-Idfu road. The Abu Dob area covers about 150km(2) of the Arabian Nubian shield at the central part of the Eastern Desert of Egypt. Most of the pegmatite is zoned; the zonation starts with milky quartz at the core followed by alkali feldspar at the margins. The feldspars vary in color from rose to milky and in composition from K-feldspar to Na-feldspar, sometimes interactions of both types are encountered. Thirteen feldspar samples were collected from different locations in the Abu Dob area for measuring the natural radioactivity of (238)U, (232)Th and (40)K using an HPGe detector. The variation in concentration of radionuclides for the area under investigation can be classified into regions of high, medium and low natural radioactivity. The average concentration in BqKg(-1) has been observed to be from 9.5 to 183675.7BqKg(-1) for (238)U, between 6.1 and 94,314.2BqKg(-1) for (232)Th and from 0 to 7894.6BqKg(-1) for (40)K. Radium equivalent activities (Ra(eq)), dose rate (D(R)) and external hazard (H(ex)) have also been determined. In the present work, the concentration of rare earth elements are measured for two feldspar samples using two techniques, Environmental Scanning Electron microscope XIL 30 ESEM, Philips, and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The existence of rare earth elements in this area are very high and can be used in different important industries. PMID:21324705

    Full Text Available This study assesses the hydrocarbon source rocks of the Belayim oilfields, central Gulf of Suez, Egypt. Detailed geochemical methods, including liquid chromatography, gas chromatography and gas chromatography–mass spectrometry, are used to characterize organic-rich facies of the Turonian–Eocene deposits. Crude oil samples are analyzed using C7 and stable carbon isotopes, in addition to analysis of the extracts, in order to throw light on the organic matter source, composition, and thermal maturity. The source rocks are mainly derived from algae and bacteria deposited under normal saline and reducing palaeoenvironmental conditions, with a minimal contribution from terrestrial organic and mainly clay-poor source rocks. This is evidenced by the n-alkane distribution, the pristane/phytane, homohopane, gammacerane index, the high concentration of cholestane, the presence of the C30 n-propylcholestanes and low diasteranes ratios. The source rock extracts range from immature to marginally mature, based on biomarker maturity-related parameters. A similar scenario is envisaged from the crude oil samples which showed a partial positive correlation with the source rocks of the Eocene Thebes Formation, and the Upper Cretaceous Brown Limestone. Our data suggest that Turonian–Santonian Matulla Formation samples may signify the presence of some oil in the study area.

  17. Sinai Trafficking: Origin and Definition of a New Form of Human Trafficking

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available The phenomenon that is coined “Sinai Trafficking” started in 2009 in the Sinai desert. It involves the abduction, extortion, sale, torture, sexual violation and killing of men, women and children. Migrants, of whom the vast majority are from Eritrean descent, are abducted and brought to the Sinai desert, where they are sold and resold, extorted for very high ransoms collected by mobile phone, while being brutally and “functionally” tortured to support the extortion. Many of them die in Sinai. Over the last five years broadcasting stations, human rights organisations and academics have reported on the practices in the Sinai and some of these reports have resulted in some confusion on the modus operandi. Based on empirical research by the authors and the analysis of data gathered in more than 200 recorded interviews with Sinai hostages and survivors on the practices, this article provides a definition of Sinai Trafficking. It argues that the term Sinai Trafficking can be used to differentiate a particular new set of criminal practices that have first been reported in the Sinai Peninsula. The article further examines how the new phenomenon of Sinai Trafficking can be framed into the legal human trafficking definition. The interconnectedness of Sinai Trafficking with slavery, torture, ransom collection, extortion, sexual violence and other severe crimes is presented to substantiate the use of the trafficking framework. The plight of Sinai survivors in Israel and Egypt is explained to illustrate the cyclical process of the trafficking practices especially endured by Eritreans, introduced as the Human Trafficking Cycle. The article concludes by setting out areas for further research.

  18. Tectonic framework of northeast Egypt and its bearing on hydrocarbon exploration

    Detailed structural study of northern and central Sinai, the northern Eastern Desert, and the northern Gulf of Suez clarified the tectonic framework of northeast Egypt. This framework is related to the movements between the African Plate and the Eurasian and Arabian Plates. Late Cretaceous folding and thrusting in response to oblique convergence between the African and Eurasian Plates formed NE-ENE oriented, doubly plunging, en echelon folds of the northern Egypt fold belt. This fold belt is well exposed in northern Sinai and a few other places but is concealed under younger sediments in the other parts of northern Egypt. Younger folding of local importance is related to dextral slip on the Themed Fault (Central Sinai) in post Middle Eocene-pre Miocene time. Early Miocene rifting of the Afro-Arabian Plate led to the opening of the Suez rift and deposition of significant syn-rift facies. Half grabens and tilted fault blocks dominate the rift. Slightly tilted fault blocks characterize the competent Middle Eocene limestones of the Eastern Desert south of the Cairo-Suez road but north of this road, Middle Eocene rocks are locally dragged on nearby E-W and NW-SE oriented faults forming fault-drag folds. Ductile Upper Eocene and Miocene rocks are also folded about gentle NW-SE oriented doubly plunging folds. The different stages of tectonic activity in northern Egypt contributed to the development of different types of structural traps as well as different source, reservoir, and cap rocks. The sedimentary history of the region indicates well developed marine sediments of Jurassic, Cretaceous, Eocene, and Miocene ages. Basin development in structurally low areas provided good sites for hydrocarbon generation and maturation.

  19. Oppositely dipping thrusts and transpressional imbricate zone in the Central Eastern Desert of Egypt

    2014-12-01

    This paper documents the 40-60 km wide ENE-WSW trending Mubarak-Barramiya shear belt (MBSB) in the Central Eastern Desert of Egypt by examining its structural styles, kinematics and geometry. Our study revealed the existence of prevalent dextral and minor sinistral conjugate shear zones. The MBSB is metamorphic belt (greenschist-amphibolite) characterized by at least three post-collisional (740-540 Ma) ductile Neoproterozoic deformation events (D1, D2 and D3) followed by a brittle neotectonic deformation (D4). D1 event produced early top-to-the-northwest thrust displacements due to NW-SE shortening. D2 produced discrete zones of NNW-trending upright folds and culminated in initiation of major NW-trending sinistral shear zones of the Najd Fault System (NFS, at c. 640-540 Ma ago) as well as steeply dipping S2 foliation, and shallowly plunging L2 lineation. NW-to NNW-trending F2 folds are open to steep and vary in plunge from horizontal to vertical. D2 deformational fabrics are strongly overprinted by D3 penetrative structures. D3 is characterized by a penetrative S3 foliation, steeply SE- to NW-plunging and shallowly NE-plunging stretching lineations (L3), asymmetric and sheath folds (F3) consistent with dextral sense of movement exhibited by delta- and sigma-type porphyroclast systems and asymmetric boudinage fabrics. D2-D3 represent a non-coaxial progressive event formed in a dextral NE- over NW-sinistral shear zone during a partitioned transpression in response to E-W-directed compression during oblique convergence between East and West Gondwana developed due to closure of the Mozambique Ocean and amalgamation of the Arabian-Nubian Shield in Cryogenian-early Ediacaran time.

  20. Mineralogical Characterization of The Alteration Facies at Gabal El-Missikat Area, Central Eastern Desert, Egypt

    International Nuclear Information System (INIS)

    The present study deals with the petrographical, mineralogical and geochemical characteristics of the alteration facies zones recognized around the shear zone at Gabal El-Missikat area, Central Eastern Desert, Egypt. Petrographically, the fresh granitic samples are composed mainly of quartz, K-feldspars (microcline and microcline perthite), plagioclase, biotite. The secondary minerals are sericite, kaolinite, muscovite, chlorite and epidote as well as zircon, apatite, fluorite, titanite and iron oxides as accessory minerals. Two alteration facies zones are recognized and namely as propylitic and advanced argillic. The propylitic facies zone is composed mainly of sericite with minor kaolinite, muscovite, quartz, relics of plagioclases, chlorite and rare epidote as well as zircon, hematite, goethite, magnetite, ilmenite, ilmenorutile, rutile, titanite, apatite, columbite and fluorite and secondary uranium minerals, the advanced argillic facies zone is composed mainly of kaolinite with minor sericite, quartz, muscovite, chlorite and rare epidote as well as zircon, hematite, goethite, magnetite, ilmenite, ilmenorutile, rutile, titanite, apatite and garnet of spessartine type as accessory minerals. The identified minerals in the studied two alteration facies zones can be grouped into three mineral groups which are: the primary minerals (pyrite, magnetite, galena, columbite and gold), the secondary minerals (uranophane, kasolite and wulfenite) and the gangue minerals (anhydrite, barite, celestine, hematite, goethite and fluorite). The identified mineral assemblage of the studied propylitic alteration facies zone may be attributed to strongly alkaline hydrothermal solutions at ph value of more than 7 with temperature varying between 350 and 450°C, while the advanced argillic alteration facies zone is essentially associated with strongly acidic hydrothermal solutions at ph value less than 7 with temperature varying between 150 and 400°C

  1. Tectonostratigraphy and depositional history of the Neoproterozoic volcano-sedimentary sequences in Kid area, southeastern Sinai, Egypt: Implications for intra-arc to foreland basin in the northern Arabian-Nubian Shield

    2013-09-01

    This paper presents a stratigraphic and sedimentary study of Neoproterozoic successions of the South Sinai, at the northernmost segment of the Arabian-Nubian Shield (ANS), including the Kid complex. This complex is composed predominantly of thick volcano-sedimentary successions representing different depositional and tectonic environments, followed by four deformational phases including folding and brittle faults (D1-D4). The whole Kid area is divisible from north to south into the lower, middle, and upper rock sequences. The higher metamorphic grade and extensive deformational styles of the lower sequence distinguishes them from the middle and upper sequences. Principal lithofacies in the lower sequence include thrust-imbricated tectonic slice of metasediments and metavolcanics, whereas the middle and upper sequences are made up of clastic sediments, intermediate-felsic lavas, volcaniclastics, and dike swarms. Two distinct Paleo- depositional environments are observed: deep-marine and alluvial fan regime. The former occurred mainly during the lower sequence, whereas the latter developed during the other two sequences. These alternations of depositional conditions in the volcano-sedimentary deposits suggest that the Kid area may have formed under a transitional climate regime fluctuating gradually from warm and dry to warm and humid conditions. Geochemical and petrographical data, in conjunction with field relationships, suggest that the investigated volcano-sedimentary rocks were built from detritus derived from a wide range of sources, ranging from Paleoproterozoic to Neoproterozoic continental crust. Deposition within the ancient Kid basin reflects a complete basin cycle from rifting and passive margin development, to intra-arc and foreland basin development and, finally, basin closure. The early phase of basin evolution is similar to various basins in the Taupo volcanics, whereas the later phases are similar to the Cordilleran-type foreland basin. The

    2008-05-01

    Full Text Available This paper assesses whether the legal independence granted to the Central Bank of Egypt (CBE under the latest legislation is factual. I followed Fry’s methodology, which assumes that the level of independence of the central bank is determined by fiscal attributes. In an attempt to develop Fry’s method, I used a simple criterion to assess the central bank’s independence, namely, that the central bank is actually independent if it can fulfill its money supply target. Applying this criterion to the CBE and some other CBs in the developed countries and emerging market economies, we find that: (i the legal independence granted to the CBE under the latest legislation is not factual; although the final objective of monetary policy is to achieve price stability, the CBE failed to fulfill its money supply target and achieve price stability, because it was responsive to political pressure and did not react to fulfill its money supply target; (ii such political pressure on the CBE is due to fiscal attributes, as measured by domestic credit to the government; (iii CBs whose independence is factual, according to our criterion, showed a negative relationship between the legal indices, as measured by the GMT index, and the fiscal attributes measured by DCGY. However, the relationship was anomalous when measured by the rate of inflation

    The relationships of Y/Nb, Th/Nb, La/Nb and Ce/Pb ratios in A-type felsic rocks from the Ediacaran Katerina Ring Complex, northernmost Arabian-Nubian Shield (ANS; S. Sinai, Egypt), are investigated in this work to understand their behavior during generation of highly evolved granitic magmas and to explore the nature of magma sources. Textural and compositional relationships of cognate Th-REE- and Nb-Ta-accessory minerals in Katerina felsic rocks show that chevkinite-group minerals (CGM), monazite, thorite, allanite and xenotime formed from residual liquids in quartz syenite porphyries, quartz monzonites and peralkaline granites, whereas in aluminous granites, allanite and monazite crystallized early, and thorite and columbite formed from residual liquids. Relationships of Y/Nb, Th/Nb, La/Nb and Ce/Pb ratios with Zr/Hf ratios in the aluminous granites and with Be abundances in the peralkaline granites suggest a decrease in La/Nb and Ce/Pb ratios in the former, and in Y/Nb and La/Nb ratios in the latter with crystallization progress. This contrasts with absence of systematic variations of Th/Nb and Ce/Pb ratios in the peralkaline compositions and of Y/Nb ratio in the aluminous ones. In this latter, Th/Nb ratio can present a significant decrease only in highly evolved compositions. An analysis of Y/Nb, Th/Nb, La/Nb and Ce/Pb relationships in worldwide OIB and subduction-related magmatic suites reveals that A-type felsic rocks with (Th/Nb)N 1 may have A1-type affinity, and those with (Th/Nb)N > 2, (La/Nb)N > 2, and (Ce/Pb)N fractionation of Th-LREE- and Nb-Ta-accessory minerals and mixing of components derived from the two granite groups may cause deviations from these compositional limits that can be evaluated using constraints imposed by Th/Nb-La/Nb, Ce/Pb-Th/Nb and Ce/Pb-La/Nb relationships in OIB and subduction-related magmatic suites. Three mantle sources might have been involved in the Ediacaran alkaline magmatism from northernmost ANS that are chemically similar

  4. Geology of Wadi Wassif Area, Central Eastern Desert, Egypt, With Emphasis on Mineralogy of Stream Sediments

    International Nuclear Information System (INIS)

    This study deals with the geology and mineralogy of stream sediments at Wadi Wassif, C.E.D., Egypt. The area is built up of igneous and metamorphic rocks of Late Precambrian age in addition to Quaternary alluviam deposits. Geologically, the area consists of metavolcanics, older granitoids, Hammamat sediments, younger granites, and Quaternary sediments filling the streams of the studied area. Microscopically, metavolcanics comprise meta andesite, metadacite and crystal tuffs. They are weakly metamorphosed to the green schist facies (chlorite zone). Hammamat sediments comprise conglomerate, sandstone, siltstone and mud stone. They are weakly metamorphosed to the chlorite zone of the green schist facies. Gravity and magnetic separation techniques in addition to microscopic examination for the studied stream sediment samples were applied to evaluate the heavy minerals concentration of these sediments. The average heavy mineral concentration of the stream sediments of Wadi Wassif is 5.56%, ranging from 1.58% and 10.91%. These heavy minerals increase from upstream to downstream of Wadi Wassif. The average contents of the concerned heavy minerals in Wadi Wassif are 0.347% for zircon, 0.058% for thorite, 0.074% for monazite, 0.097 for titanite, 0.038% for rutile. The other heavy minerals include epidot, garnet in addition to opaque minerals; magnetite, ilmenite and hematite. The radiometric study of the stream sediments of Wadi Wassif indicates that the average concentrations of U and Th are 2.9ppm and 17ppm respectively, ranging from 1 to 4ppm for U and 8 to 28ppm for Th, which reveals a significant fractionation during weathering of these sediments.

  5. Structural elements and incremental strain history of the basement rocks of Um Had area, central Eastern Desert, Egypt

    International Nuclear Information System (INIS)

    The Um Had area, central Eastern Desert, Egypt shows a regional stretching in the NW-SE and a contraction in the NE-SW direction. Major NW-SE folds, small recumbent folds, and local thrusts and reverse faults were recognized. Complicated relation between folds and boudinage was identified. This stretching amount ranges from 1.282 to 1.309. Earlier coaxial and later non-coaxial strains were inferred. The change from axial to non-coaxial stress regime was gradual and the latter was associated with minor clockwise and anticlockwise rotation of structural elements. During the non-coaxial strain, strain fringes were formed as a consequence of the high circulation of fluids in low temperature and high pressure conditions. Superimposed strain fringes indicating right- and left-lateral senses of movement were recognized. At least three generations of fringes were recognized, implying three stages of non-coaxial stretching. Each generation has about 15 increments which show irregular strain gradient and intensity over the different increments. Eastwards, the strain increments became mature and westwards, the finite strain increases. The strongest finite strain was found in a narrow belt delimiting the basement rocks on the west and underlying the Phanerozoic sediments. Chocolate-tablet structure was recorded and indicates later multidirectional tension. Not all Nubia Sandstone exposures are overlying the basement rocks and some are separated by NW-SE normal faults. Major NW-SE normal faults are cutting basement rocks of different ages. (author)

  6. Natural radionuclide concentrations in granite rocks in Aswan and Central-Southern Eastern Desert (Egypt)) and their radiological implications

    International Nuclear Information System (INIS)

    Different types of granites, used extensively in local construction, were collected from five localities in Egypt, namely: Abu Ziran (Central Eastern Desert), Gabal El Maesala (Aswan) and three areas from Wadi Allaqi, (Gabal Abu Marw, Gabal Haumor and Gabal um Shalman), in the South Eastern Desert. Granite samples were studied radiologically, petrographically and geochemically. The contents of natural radionuclides 226Ra, 232Th and 40K) were measured in investigated samples by using gamma spectrometry [NaI (Tl) 3'x3']. The activity concentrations of 226Ra, 232Th and 40K in the selected granite samples ranged from 9±0.5 to 111±7, 8±1 to 75±4 and 100±6 to 790±40 Bq kg-1, respectively. The external hazard index (Hex), absorbed dose and annual effective dose rate were evaluated to assess the radiation hazard for people living in dwellings made of the materials studied. The calculated radium equivalents were lower than the values recommended for construction materials (370 Bq kg-1). The excess lifetime cancer risks were also calculated. Petrographically, the granites studied are varied in the form of potash-feldspar, quartz, plagioclase, mica and hornblende. The accessory minerals are zircon, apatite and allanite. Geochemically, the chemical composition of the granite is studied especially for major oxides. They are characterized to have SiO2, K2O, Na2O and Al2O3 with depletion in CaO, MgO, TiO2 and P2O5.

    An integrated approach for geophysical, geological and mineralogical data was followed for Um Naggat area, Central Eastern Desert, Egypt, in order to delineate its mineralized zones. The albitized granites are well-defined on the Th- and U-channel images, by their anomalous shapes, reaching 150 ppm and 90 ppm respectively, beside low K content. Interpretations of the aeromagnetic maps delineated four regional structural trends oriented due NNW, NW, ENE and E-W directions. They are identified as strike-slip faults, which coincide well with field observations, where NW-trending faults cut and displace right laterally ENE-trending older ones. The interaction between these two strike-slip fault systems confining the albite granite is easily identified on the regional data presenting longer wavelength anomalies, implying deep-seated structures. They could represent potential pathways for migration of enriched mineralized fluids. Geochemically, albite granites of peraluminous characteristics that had suffered extensive post-magmatic metasomatic reworking, resulted into development of (Zr, Hf, Nb, Ta, U, Th, Sn) and albite-enriched and greisenized granite body of about 600 m thick, and more than 3 km in strike length. The albite granite is characterized by sharp increase in average rare metal content: Zr (830 ppm), Hf (51 ppm), Nb (340 ppm), Ta (44 ppm), and U (90 ppm). Thorite, uranothorite, uraninite and zircon are the main uranium-bearing minerals of magmatic origin within the enclosing granite. However, with respect to Zr, Nb, and Ta, the albitized granite can be categorized as rare metal granite. The integration of airborne geophysical (magnetic and γ-ray spectrometric), geological, geochemical and mineralogical data succeeded in assigning the albite granite of Um Naggat pluton as a mineralized zone. This zone is characterized by its high thorium and uranium of hydrothermal origin as indicated by its low Th/U ratio, with rare metals mineralization controlled by two

    Nearly 2000 liver transplants have been performed over the past 12 years at Mount Sinai, with a recent exponential growth in living donor surgeries. Living-donor liver transplantation has emerged as an important option for our patients with end-stage liver disease. We are only beginning to recognize fully the advantages that 'scheduled' liver transplantation can offer. In this era of severe cadaver organ shortages, living donation offers patients the option of liver replacement in a timely fashion, before life-threatening complications of hepatic failure and/or carcinoma progression prohibit transplantation. The next era of transplantation at Mount Sinai will bring significant increases in the number of transplants performed with living donors, with projections of over 50% of the total transplants each year expected to involve living donations. We are committed to offering this option while recognizing that donor safety remains paramount and cannot be overemphasized. Proper donor and recipient selection, as well as surgical experience are imperative to success with this technically demanding procedure. Recurrent disease after transplantation, particularly with hepatitis C, remains a challenge clinically. Further investigations into the pathogenesis of the rapid progression of recurrent hepatitis C need to be addressed. Living donor transplantation could be an important option for these patients and would allow timely transplantation and the potential for improved survival in patients with hepatocellular carcinoma.

    Abdelsalam, Tarek I.; Darwish, Ziad; Hatem, Tarek M.

    Egypt is currently experiencing the symptoms of an energy crisis, such as electricity outage and high deficit, due to increasing rates of fossil fuels consumption. Conversely, Egypt has a high solar availability of more than 18.5 MJ daily. Additionally, Egypt has large uninhabited deserts on both sides of the Nile valley and Sinai Peninsula, which both represent more than 96.5 % of the nation's total land area. Therefore, solar energy is one of the promising solutions for the energy shortage in Egypt. Furthermore, these vast lands are advantageous for commissioning large-scaled solar power projects, not only in terms of space availability, but also of availability of high quality silicon (sand) required for manufacturing silicon wafers used in photovoltaic (PV) modules. Also, rural Egypt is considered market a gap for investors, due to low local competition, and numerous remote areas that are not connected to the national electricity grid. Nevertheless, there are some obstacles that hinder the progress of solar energy in Egypt; for instance, the lack of local manufacturing capabilities, security, and turbulent market in addition to other challenges. This paper exhibits an experience of the authors designing and installing decentralized PV solar systems, with a total rated power of about 11 kW, installed at two rural villages in at the suburbs of Fayoum city, in addition to a conceptual design of a utility scale, 2 MW, PV power plant to be installed in Kuraymat. The outcomes of this experience asserted that solar PV systems can be a more technically and economically feasible solution for the energy problem in rural villages.

  10. Mineralogy and Radioactivity of the Acidic Dokhan Volcanics of Gabal Nuqara, Central Eastern Desert. Egypt

    International Nuclear Information System (INIS)

    The present work aims to study the mineralogy as well as the radioactivity of the acidic Dokhan volcanic in Gabal Nuqara area to identify the minerals that responsible for the radioactivity. The Dokhan volcanic of Gabal Nuqara, Central Eastern Desert are related to fissure-type eruption and are subdivided into intermediate and acidic volcanics. The acidic Dokhan volcanics rocks are located as two elongated flows of rhyolite, dacite and their tuffs, trending NW-SE direction and cut by younger granites and younger gabbros. Radiomatically, tuffs and dacite rocks show low radioactivity, while the concerned rhyolite exhibits relatively high eTh and eU contents (140 ppm and 89 ppm in average respectively). Moreover, an anomalous content was recorded in rhyolite rocks where eTh and eU contents are 745 ppm and 280 ppm in average, respectively. The detailed mineralogical studies, using ESEM and XRD techniques, indicate the presence of some primary radioactive minerals that are responsible for the radioactivity of the Nuqara rhyolites (e.g. thorite and uranothorite). Furthermore, samarskite, zircon and allanite occur as uraniferous accessory minerals. The mineral chemistry by EPMA analysis of thorite reflects the main following components; ThO2 (38 %), SiO2 (33 %) and UO2 (6 %), while the main constituents of uranothorite are ThO2 (40 %), SiO2 (20 %), and UO2 (12 %). Beside, the studied zircon crystals display a large chemical variability between core and rim. Zircon and thorite from Nuqara rhyolite are demonstrably magmatic origin, can be attributed concentrated in the rhyolite extrusive

  11. Earthquake hazard analysis in northern Egypt

    International Nuclear Information System (INIS)

    Earthquake activity and seismic hazard analysis are important components of the seismic aspects for very essential structures such as major dams and nuclear power plants. Setting of nuclear power plants becomes of increasing important in northern Egypt with the commitment towards promoting nuclear electric generation. Therefore, the annual seismic hazard maps with non-exceedence probability of 80%, 85% and 90% are given. These maps show that northern Egypt is severely affects by earthquakes from potential sources around Sinai peninsula. Three sites (Nile Delta, Cairo, and Ismailia region) have been chosen to estimated the earthquake hazard in more detailes to serve as a basic parameter to the safety factor of different projects in these regions. A seismic safety factor of intensity 8.5 should be considered in designing the vital projects in northern Egypt. (author)

    Quseir-Safaga area, Central Eastern Desert, Egypt, includes Duwi Formation, which contains uranium-bearing phosphate beds. The present work used the integrated carborne γ-ray spectrometric data, X-ray analysis and HPGe γ-ray spectrometer data to investigate the radioactive zones at this area. Carborne γ-ray spectrometric survey revealed an increase of equivalent uranium, up to 182 ppm. Maps were drawn to show the results of the three radioelements K, eU, eTh and the eU/eTh ratio. The eU and (eU/eTh) maps reveal that there are twelve important anomalies, associated mainly with phosphate mines. The Hamrawein mines at the northwestern part in the study area seem to represent the highest U-anomalies. Twelve phosphate samples were collected from the determined twelve anomalies. They were analyzed with HPGe detector gamma-ray spectrometer. It was found that the results of radioelement concentrations by carborne survey agree well with that obtained by HPGe. Both of them show that phosphate mines effectively contribute to eU anomalies, occurring in the study area. Meanwhile, 40K, 238U and 232Th concentrations in phosphate samples range from 91 to 169, 864 to 3104 and 28.4 to 106 Bq/kg respectively. The highest concentration of 238U (3104 Bq/kg) occurs in the north of the studied area, close to Hamrawein city. The average concentration of 238U in the analyzed samples is 1766 Bq/kg, which is 53 times higher than the worldwide average value reaching 33 Bq/kg. The highest 232Th concentration value reaching 106 Bq/kg is 2.4 times higher than the worldwide value attaining 45 Bq/kg. The absorbed dose rate for the phosphate samples shows the highest value reaching 1468 nGy/h. This is more than 25 times the worldwide average value 58 nGy/h. The annual effective absorbed dose is also high and reached 1.8 mSv/y, which is about twice higher than the permitted value for public exposure of 1.0 mSv/y. The maximum external hazardous index value of 9.2 is more than nine times the unity

    Egypt is the most populous country in the Arab world and the second most populous country in Africa, with 65.5 million people living in a land area of 384,344 square miles as of mid-1998. There were 28 births and 6 deaths per 1000 population, as well as 63 infant deaths for every 1000 live births, and a population growing in size at 2.2% annually. The average Egyptian woman has 3.6 births during her reproductive lifetime and life expectancy is 65 years for men and 69 years for women. Egypt has major issues to address with regard to the management and use of its water resources, balancing the protection and use of rural lands, and expanding industry while protecting the air, water, and land. Much of Egypt's water is polluted and its soil damaged and depleted due to irrigation-related salinization. With Cairo and Alexandria already densely populated, the proportion of Egypt's population expected to live in urban areas should exceed 60% by 2025. Almost all of Egypt's population lives along the banks of the Nile and its delta, almost all of the country's agricultural production occurs on 5% of that land, and less than 1% of the land is protected. Population momentum will cause Egypt's population to grow a projected 51% by 2025 even though 47% of married women use some form of contraception. 51% of Egyptian adults are literate and tense relations with Israel influence Egypt's public expenditures and foreign assistance.

    International Nuclear Information System (INIS)

    Radioactivity measurements and U and Th content determinations were carried out on 3 small granitic plutons, Gabal Abu Aqarib, Gabal El-Himeiyer and Gabal Um Zarabit, in the Central Eastern Desert. The Abu Aqarib and Um Zarabit alkali feldspar granites are elongated bodies intruded into the Dokhan Volcanics, whereas El-Himeiyir is intruded into an ophiolotic melange section. Compared to the average content of U and Th of world granites, El-Himeiyir alkali felspar granites show normal content of both U and Th. On the other hand, Abu Aqarib alkali feldspar granite shows some enrichments in both U and Th, whereas Um Zarabit granite shows enrichments in U contents only. The two discovered anomalous radioactive sites show 154 ppm U, and 256 ppm Th contents for Gabal Abu Aqarib site, and 24 ppm U, and 107 ppm Th contents for El-Himeiyir one. The two sites are associated with NE-trending shear zones and exhibit hydrothermal alteration features such as hematitization and silicification. The high radioactivity is ascribed to unusual accumulations of zircon and/or apatite; however, some of the enriched U may be of epigenetic origin. (author)

    On 22 January 2013 an earthquake with local magnitude ML 4.1 occurred in the central part of the Gulf of Suez. Six months later on 1 June 2013 another earthquake with local magnitude ML 5.1 took place at the same epicenter and different depths. These two perceptible events were recorded and localized by the Egyptian National Seismological Network (ENSN) and additional networks in the region. The purpose of this study is to determine focal mechanisms and source parameters of both earthquakes to analyze their tectonic relation. We determine the focal mechanisms by applying moment tensor inversion and first motion analysis of P- and S-waves. Both sources reveal oblique focal mechanisms with normal faulting and strike-slip components on differently oriented faults. The source mechanism of the larger event on 1 June in combination with the location of aftershock sequence indicates a left-lateral slip on N-S striking fault structure in 21 km depth that is in conformity with the NE-SW extensional Shmin (orientation of minimum horizontal compressional stress) and the local fault pattern. On the other hand, the smaller earthquake on 22 January with a shallower hypocenter in 16 km depth seems to have happened on a NE-SW striking fault plane sub-parallel to Shmin. Thus, here an energy release on a transfer fault connecting dominant rift-parallel structures might have resulted in a stress transfer, triggering the later ML 5.1 earthquake. Following Brune's model and using displacement spectra, we calculate the dynamic source parameters for the two events. The estimated source parameters for the 22 January 2013 and 1 June 2013 earthquakes are fault length (470 and 830 m), stress drop (1.40 and 2.13 MPa), and seismic moment (5.47E+21 and 6.30E+22 dyn cm) corresponding to moment magnitudes of MW 3.8 and 4.6, respectively.

    Supra-subduction zone ophiolites in the Egyptian Central Eastern Desert (CED) occur as clusters in its northern (NCEDO) and southern (SCEDO) parts, displaying abundant island arc-boninitic and MORB/island-arc geochemical affinities, respectively. An amphibolite belt, including the investigated massive to slightly foliated Wadi Um Gheig (WUG) amphibolites, is exposed in the southeast most of the NCEDO thrusting over the El Sibai gneissic association and intruded by late- to post-orogenic granitoids and gabbros. The WUG rocks are metamorphosed under epidote amphibolite to common amphibolite facies. The amphiboles are calcic and represented by actinolitic hornblende to magnesio-hornblende in the epidote amphibolites and magnesio- to ferro-hornblende in the amphibolites. Plagioclase composition varies from pure albite (An3-8) in the epidote amphibolites to andesine and labradorite (An36-65) in the amphibolites. The estimated P-T conditions are in favor of their metamorphism under epidote amphibolite (c. 550-600 °C and 2-3 ± 1.5 kbar) and amphibolite (c. 618-720 °C and 3-6 ± 1.5 kbar) facies. The peak metamorphic conditions point to a burial depth of c.15-20 km. Geochemically, the WUG amphibolites show basaltic to andesitic compositions of tholeiitic affinity. They display LILE-enriched MORB-normalized patterns with negative Nb anomalies characteristic of the subduction-related rocks. However, their chondrite-normalized rare-earth element (REE) patterns vary from LREE-depleted (LaN/YbN = 0.29 to 0.49) to LREE-enriched (LaN/YbN = 2.97 to 3.74). Few samples show major and trace element contents typical of boninitic rocks, including U-shaped REE pattern. On the standard tectonic discrimination diagrams the WUG amphibolites plot mostly in the island-arc fields with some samples of MORB and boninitic affinities. Greenschist facies metamorphosed NCEDO obviously share these geochemical characteristics, implying formation in the same tectonic environment, i.e. forearc basin

  4. Spectral Discrimination of Uranium-Bearing Trachyte in Wadi Kareim-Wadi El Atshan Area, Central Eastern Desert of Egypt Using Landsat Enhanced Thematic Mapper Data (ETM+)

    International Nuclear Information System (INIS)

    The basement rocks around Wadi Kareim-Wadi El Atshan in the Central Eastern Desert of Egypt represent a structurally and metamorphic complex assemblage of folded and faulted meta sediment, meta volcanic and Hammamat sedimentary rocks into a series of trends. Geological mapping in this region is challenging, primarily due to difficult access, complexity of structures, and lack of resolution and areal integrity of lithological differentiation using conventional mapping techniques. Spectral analysis of selected bands of Landsat-7 ETM+ data covered the studied area, in synergy with previous geological field observation, proved effective resolving of geological mapping problems in the study region, with emphasis on discrimination and mapping the trachyte that exposed in the area which considered as favorable host rock for uranium and/or thorium mineralization . A variety of remote sensing processing techniques of the digital data of Landsat-7 ETM+ were applied successfully for lithologic mapping in W. Kareim-Wadi El Atshan area, showing improvement in discrimination of sill, dyke and plug trachyte rocks. Not all Red, Green and Blue (RGB) band combination was useful to obtain basic knowledge of the study area. The traditional RGB (3,2,1 true color image and 7,4,2 false color image) band combination could not distinguished between some outcropping units, and not delineate a definite contacts between them as well as delineation of the uranium bearing trachyte. The adopted composite ratio image produced from combination of 3/l(Red), 5/4(Green) and 5/7(Blue) band ratios were successfully used to discriminate the uranium-bearing trachyte and demonstrate the benefit of the enhance ETM+ remote sensing data for lithologic and structural mapping. While Principal Component analysis and de correlation stretching techniques add further successful tools to outline and define the uranium-bearing trachyte that extend all over W. Kareim-W.

  7. Radiometric Characterization of Sand in Northeast Sinai

    International Nuclear Information System (INIS)

    Thirty-eight locations covering an area of 350 km2 in northeast Sinai were investigated by gamma-ray spectroscopy using a 50% HPGe detector. The limits of area are Al-Arish North, El-Hasana South, El-Oga East, and El- Gifgafa West. The range of activity concentrations of 238U, 234Th, 226Ra, 232Th and 40K are 0.6-35.2, 3.9-22.6, 4.7-29.6, 4.7-23.9, and 108-295 Bq/kg for sands, respectively. 137Cs in the region ranged from 0.1-8.0 Bq/kg. No major difference between the studied area and that previously investigated in the costal area in North Sinai. Reliable correlations (R2 = 0.8-0.9) among 238U, 234Th, and 226Ra isotopes was obtained. On the other hand, low correlation (R2 = 0.6-0.7) was obtained from the analysis of the isotopes of 238U-seies and 232Th. No evidence of correlation between the concentrations of radioisotopes and pH contents, TOM, and grain size were found. The soil-plant transfer factor are 226Ra and 232Th, 40K, and 137Cs, respectively. The wild vegetations collected from the studied area have average concentrations of 1.9, 1.4, 1.3, 254, and 0.3 for 234Th, 226Ra, 232Th, 40K, and 137Cs, respectively.

    Honey bees are critical pollinators of important agricultural crops. Recently, high annual losses of honey bee colonies have prompted further investigation of honey bee infecting viruses. To better characterize the recently discovered and very prevalent Lake Sinai virus (LSV) group, we sequenced currently circulating LSVs, performed phylogenetic analysis, and obtained images of LSV2. Sequence analysis resulted in extension of the LSV1 and LSV2 genomes, the first detection of LSV4 in the US, and the discovery of LSV6 and LSV7. We detected LSV1 and LSV2 in the Varroa destructor mite, and determined that a large proportion of LSV2 is found in the honey bee gut, suggesting that vector-mediated, food-associated, and/or fecal-oral routes may be important for LSV dissemination. Pathogen-specific quantitative PCR data, obtained from samples collected during a small-scale monitoring project, revealed that LSV2, LSV1, Black queen cell virus (BQCV), and Nosema ceranae were more abundant in weak colonies than strong colonies within this sample cohort. Together, these results enhance our current understanding of LSVs and illustrate the importance of future studies aimed at investigating the role of LSVs and other pathogens on honey bee health at both the individual and colony levels.

  13. Ancient Egypt in our Cultural Heritage?

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available Inspiration derived from ancient Egypt is usually expressed through the Egyptian motifs in arts and popular culture of the 19th and 20th centuries, as well as through the non-scientific interpretations of the culture, very much based upon the Renaissance ones. The number and variety of material and non-material traces of this fascination are most expressed in the countries where, along with the early support for the institutional development of Egyptology, there existed economically potent educated middle classes (Western and Central Europe, USA, but may also be traced elsewhere. The public fascination by ancient Egypt has not ceased by the times of foundation of Egyptology, marked by the decipherment of the hieroglyphic script in 1822. Until the end of the 20th century Egyptologists have rarely dealt with the prelude to their discipline, limiting their interest to the critical approach to ancient sources and to noting the attempts to interpret the hieroglyphic script and the function of pyramids. However, the rising importance of the reception studies in other disciplines raised the interest of Egyptologists for the "fascination of Egypt", thus changing the status of various modes of expressing "Egyptomania" – they have thus become a part of the cultural heritage, registered, documented, preserved and studied. The research of this kind is only beginning in Serbia. The line of inquiry enhances the knowledge of the scope, manifestations and roles of the interest in Egypt, not limited by the national or political borders. On the other hand, the existence of the cultural heritage similar to the wider European view of ancient Egypt – short remarks by Jerotej Račanin, Kandor by Atanasije Stojković, the usage of architectural motifs derived from Egypt, the emergence of small private collections, to mention several early examples – all show that the research into the reception of ancient Egypt may contribute to the knowledge about the history

  15. ESR Studies and Dating of Egyptian Gypsum at Ras Mala'ab, Sinai, Egypt

    International Nuclear Information System (INIS)

    A gypsum sample from the famous gypsum-anhydrite evaporitic deposit composing the Ras Mala'ab Formation, Upper Miocene, occurring at Ras Mala'ab, on the east coast of the Gulf of Suez, was subjected to (ESR) dosimetric studies. Also, (ESR) was used to date the formation or most recent recrystallization of that gypsum. The gypsum derivative (ESR) spectrum is characterized by the large broad Fe2+ signal (g=2.50) and HF-sixtet Mn2+ signals. Only the characteristic gypsum signal (G l, g=2.0040) was detected between the third and fourth lines of the HF-Mn2+ which is attributed to the electron-center SO3-. This signal was sensitive to artificial γ-irradiation and showed significant enhancement using a γ-dose of 550 Gy. Also, the signal was very stable up to 400 oC. The gypsum sample with a total dose (TD) of 1500 Gy, determined graphically by extrapolating the linear relationship between defect concentration and the artificial γ-doses for (G l, g=2.0040) and an annual dose (D) due to cosmic rays (0.3 mGy), yielded an age of 5.00 Ma. This could mean the age of formation or latest recrystallization of this gypsum deposit. The geologic age assignment of the Ras Mala'ab Group including the evaporitic gypsum unit, is Middle to Late Miocene. It is directly overlain by the Pliocene elastics at the locality of Ras Mala'ab. This might suggest that these evaporitic gypsum facies represent the top of the Miocene in the Gulf of Suez area, since the Miocene-Pliocene boundary is now put at 5.00-5.50 Ma ago. Therefore, the ESR age of the Ras Mala'ab gypsum is consistent with the geologic age assignment

    2015-07-09

    An integrated [very low frequency (VLF) electromagnetic, magnetic, remote sensing, field, and geographic information system (GIS)] study was conducted over the basement complex in southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (34 mm on 17–18 January 2010) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) spatial analysis in a GIS environment revealed that the distribution of the water-bearing features (conductive features) corresponds to that of fractures, faults, shear zones, dike swarms, and wadi networks; (2) using VLF (43 profiles), magnetic (7 profiles) techniques, and field observations, the majority (85 %) of the investigated conductive features were determined to be preferred pathways for groundwater flow; (3) northwest–southeast- to north–south-trending conductive features that intersect the groundwater flow (southeast to northwest) at low angles capture groundwater flow, whereas northeast–southwest to east–west features that intersect the flow at high angles impound groundwater upstream and could provide potential productive well locations; and (4) similar findings are observed in central Sinai: east–west-trending dextral shear zones (Themed and Sinai Hinge Belt) impede south to north groundwater flow as evidenced by the significant drop in hydraulic head (from 467 to 248 m above mean sea level) across shear zones and by reorientation of regional flow (south–north to southwest–northeast). The adopted integrated methodologies could be readily applied to similar highly fractured basement arid terrains elsewhere. © 2015 Springer Science+Business Media Dordrecht

    Egypt belongs to the arid to extremely arid zone. Hot springs or wells are chiefly distributed over the areas of the Golf of Suez shoreline, along the Red Sea coast and in the Bahariya, Dakhla and Kharga oasis in the Western Desert. The Red Sea with it`s branches into the Gulf of Suez and the Gulf of Aqaba/Jordan valley is the northern end of the East African Rift, which is tectonically active and yields further south known geothermal resources (e.g. in Kenya). Thus, a relatively high het flow zone exists on the eastern border of the Gulf of Suez, on Sinai peninsula. The hot springs of Ayun Musa, Hammam Faraon and El Sokhna are located there. Hammam Faroun is the hottest spring in Egypt with water temperature of approx. 70 C. This paper compiles previous studies from Egypt to elucidate the geothermal potential of Egypt and opportunities to make use of it. (orig.) [Deutsch] Aegypten gehoert zur ariden bis extrem ariden Zone. Heisse Quellen oder erbohrte heisse Waesser finden sich hauptsaechlich entlang der Kueste des Golfs von Suez und des Roten Meeres, sowie in den Oasen Bahariya, Dakhla und Kharga in der westlichen Wueste. Das Rote Meer mit seinen Verzweigungen in den Golf von Suez und in den Golf von Akaba/Jordangraben bildet den noerdlichen Abschluss des Ostafrikanischen Grabensystems, das tektonisch sehr aktiv ist und weiter suedlich (z.B. in Kenia) bekannte geothermische Ressourcen bietet. Eine Zone mit hohem geothermischen Waermefluss befindet sich dementsprechend auch am oestlichen Rand des Golfs von Suez, der zur Halbinsel Sinai gehoehrt. Hier werden die heissen Quellen von Ayun Musa, Hammam Faraon und El Sokhna angetroffen. Hammam Faraon ist die heisseste Quelle Aegyptens mit Wassertemperaturen von etwa 70 C. Die vorliegende Arbeit versucht, einige fruehere Studien aus Aegypten zusammenzufassen und das geothermische Potential Aegyptens mit den Moeglichkeiten seiner Nutzung aufzuzeigen. (orig.)

    This chapter reviews the evolution of Egypt's nuclear program, the major factors that influenced the successive series of nuclear decisions, and the public debate over the far-reaching program attempted by the late President Anwar El-Sadat. Egypt's program is important, not only because it was the first Arab country to enter the nuclear age, but because it is an ambitious program that includes the installation of eight reactors at a time when many countries are reducing their commitment to nuclear power. Major obstacles remain in terms of human, organizational, and natural resource constraints. 68 references, 1 table

  5. Current developments in uranium exploration activities in Egypt

    International Nuclear Information System (INIS)

    Current developments in uranium exploration activities since 1993 are summarized, with a brief history of uranium exploration in Egypt. New target for these exploration activities are also outlined. Previous exploration techniques used were: airborne radiometric and magnetic surveys, ground radiometric surveys, regional and detailed geologic mapping, exploratory mining works at the Wadi level, limited diamond drilling, as well as all supplementary laboratory works. Most of these activities were concentrated on the Eastern Desert terrains, particularly in granitic rocks. Main discoveries are four uranium occurrences in Pan African younger granites in addition to one at the contact of bostonite and felsite dykes in metasediments and one in psammitic gneisses in the Eastern Desert, as well as one in siltstone in a Paleozoic sedimentary basin within granitic rocks in Sinai. Two new activities are now underway: exploratory drilling programs in the uranium occurrences in the Eastern Desert and Sinai with newly acquired equipment, and experimental heap leaching of the low grade uranium ores at the site. In addition, some other techniques have been strengthened and updated such as well logging, airborne spectrometric surveys and ground geophysical surveys. Exploration activities have been recently directed also to new target areas in sedimentary formations and intracratonic sedimentary basins. The possibility of the occurrence of unconformity related deposits are also considered. (author). 8 refs, 9 figs

    Northeastern corner of Africa, lying at the crossroads between the two continents of Europe and Asia (in the Sinai Peninsula), while bordering Libya, Sudan, Israel and the Red Sea. Egypt is the most ancient tourist country in the world. Several health fact-finding missions in the last few years were made to this small country that is frequently defined by the Valley of the Nile. With the spreading deserts on either side, or a very rich heritage of ancient relics, these scenic vistas are without equal elsewhere in the world. Although there are significant cultural differences among the population, Egypt has a long history of ethnic and religious compassion. Among the many rarities, main tourist attractions include the three great Pyramids of Giza and the Sphinx, amazing ancient wonders of the world. These fact-finding missions included how health and medical care are defined, how people and culture are intertwined with its physical features, land use, and the economy and its resources.

  11. Inventory of Agricultural Land Area of Egypt Using Modis Data

    International Nuclear Information System (INIS)

    A new generation of satellite data has been emerged since the launch of the Moderate Resolution Imaging Spectro radiometer (MODIS), in 1999, for monitoring land resources and terrestrial environments. Agricultural land area of Egypt in 2005 was estimated using MODIS data. Four scenes were utilized to extract the total country area. MODIS vegetation Indices product (MOD 13 QI) was the most suitable to extract the total gross cultivated land area of Egypt. An unsupervised classification algorithm was applied to estimate the cultivated land area, which approached 8.2 million feddans in 2005. The Nile Delta contains the majority of agricultural lands (63.2%). The Nile Valley and EI-Fayoum Depression possess 33.9% and the remaining little percent (∼3%) represents the scattered agricultural land along the Suez Canal, Sinai and the Western Desert. The classification accuracy of agricultural land reached 84%, revealing higher confidence of assessment. The present study asserts on the importance of using remote sensing in monitoring agricultural land resources

  14. Integration of the security systems in the architectural design of nuclear and important buildings in Egypt

    International Nuclear Information System (INIS)

    The new and emerging threats to buildings and infrastructure which are faced by todays engineering design and facility management community in Egypt demand new approaches and solutions that are innovative and increasingly based on risk management principles. In the wake of the damage of Taba hotel in south Sinai (2004) and Sharm El-Sheik hotels in Egypt (July, 2005), there was a growing awareness of public vulnerability to terrorist attacks. This awareness leads to increase the expectations form and responsibilities of the architects, engineers and construction professionals This study reviews and assesses different types of threats to nuclear and important buildings. It identifies also the architectural design, vulnerability and risk management that can enhance security. It also introduces a new approach for integration of architectural design and security in nuclear and important buildings in Egypt. The results shows that escalating threats and risks to important buildings and infrastructures change the role of planners, architects, engineers and builders by increasing the focus on the importance of applying viable security principles to the building designs. Architects in Egypt can assume an important role in improving the life-safety features of important buildings by increasing and integrating new security principles and approaches to improve the security and performance of the buildings against man made disasters

    This paper deals with the hydrogeology and isotopic composition of water samples collected from selected spring in sinai (e.g. Algudierate, Alqusiema, qidis and Isram) in order to identify their genesis, their interaction with the host rocks and mixing trend. Results of isotopic composition have indicated the similarity in the hydrogeologic situation of Ain qidis and Ain-al-gudierate, while Ain Isram has shown a marked difference in its stable isotope and this could be due to evaporation effect. The isotopic and hydrochemical constituents of the studied springs reflect eater of a meteoric origin with a possible contamination from surficial materials (evaporates) and deeper aquifers. 6 figs., 2 tabs

We define such a system space-temporal Sinai billiard We dis- cuss the problem in semiclassical approach. We show that in semiclassical regime the formation of trapped periodic semiclassical orbits inside the sys- tem is unavoidable. This leads to general expression of survival probabilities and scattering time delays, expanded to the chaotic Pollicott-Ruelle reso- nances. Finally, we comment on possible generalizations of these aspects to relativistic quantum field theory.

    One hundred and sixty samples of groundwater from nearly all parts of Egypt have been collected and chemically analyzed in order to assess the country's geothermal potential. The samples considered to be thermal include 20 wells ( T > 35° C), 4 springs ( T > 30° C) and 1 spring not included in the present inventory. The remaining samples, together with data from the literature, establish background chemistry. The hottest springs are located along the east shore of the Gulf of Suez: Uyun Musa (48°C) and 'Ain Hammam Faraoun (70°C). Additional warm springs are located along both shores of the Gulf of Suez and this region is the most promising for geothermal development. The Eastern Desert of Egypt, particularly the coastal area adjacent to the Red Sea has above normal heat flow ( ~ 72.0 Egypt can be considered thermal including several reported "hot springs." Application of the silica, NaKCa. and NaKCaMg geothermometers does not indicate the presence of a high temperature geothermal resource at any area we visited.

On the left is an optical image from the Landsat Thematic Mapper, and on the right is a radar image from the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR). This comparison shows that the visible and infrared wavelengths of Landsat are only sensitive to the materials on the surface, while the radar wavelengths of SIR-C/X-SAR can penetrate the thin sand cover in this arid region to reveal details hidden below the surface. Field studies in this area indicate that the L-band radar can penetrate as much as 2 meters (6.5 feet) of very dry sand to image buried rock structures. Ancient drainage channels, shown at the bottom of this image, are filled with sand more than 2 meters (6.5 feet) thick and therefore appear dark because the radar waves cannot penetrate them. Only the most recently active channels are visible in the Landsat scene. Some geologic structures at the surface are visible in both images. However, many buried features, such as rock fractures and the blue circular granite bodies in the upper center of the image on the right, are visible only to the radar. The Safsaf Oasis is located near the bright yellow feature in the lower left center of the Landsat image. Scientists are using the penetrating capabilities of radar imaging in desert areas to study structural geology, mineral exploration, ancient climates, water resources and archaeology. Each image is 30.8 kilometers by 25.6 kilometers (19.1 miles by 15.9 miles) and is centered at 22.7 degrees north latitude, 29.3 degrees east longitude. North is toward the upper right. In the Landsat image, the colors are assigned as follows: red is Band 7 (mid-infrared); green is Band 4 (near infrared); and blue is Band 1 (visible blue light). The colors assigned to the radar frequencies and polarizations are as follows: red is L-band, horizontally transmitted and received; green

    The present work was established to determine the applicability of local Egyptian kaolinite and blast furnace slag (BFS) as raw materials toward the synthesis of geopolymers and subsequent immobilization of cobalt-60, which is one of the most abundant radionuclides generated in radioactive waste streams in Egypt. XRF, XRD, FT-IR, and SEM techniques were used to characterize the local raw materials and their corresponding alkali activated products. Metakaolin (MK) was obtained by thermal treatment of Egyptian Sinai kaolin 750 °C/4 h. MK and five different BFS content (5, 10, 30, 50 and 80%) were used to synthesize geopolymeric matrices using an alkaline activator of Si-modulus = 1.35 at solid/liquid ratios of 0.8. Compressive strength tests were performed indicating that 50% BFS addition gave the highest values of compressive strength. The IAEA standard leaching tests of cobalt-60 from the solidified waste matrices were carried out. The effective diffusion coefficients of cobalt-60 radionuclides from the solidified waste matrices were calculated to be in the order of 10-14 cm2/s. Leaching of radionuclides was examined to be controlled by the wash-off mechanism with very acceptable values. These results gave encouragement that the tested Egyptian raw materials can be conveniently applied for the synthesis of geopolymers that can be used as a low-cost and high-efficiency materials for the immobilization of radioactive waste.

  5. Inter-comparison study of the population dose due to gamma radiation in the coast of north sinai between rafah and bir-el-abd areas

    International Nuclear Information System (INIS)

    This study compares the external dose due to the y-ray emitting radionuclides in various areas in north Sinai, Egypt. The whole area was divided into 10 regions. The average absorbed dose rates were evaluated for each region. It was found that Zaranik protected area and Al-Massaid have the highest values of 69.0 and 54.7 nGy h-1 respectively. The corresponding values of the remaining regions were below 21 nGy h-1. The mean annual effective dose equivalent for the four largest cities Rafah, El-Sheikh Zuwaied, Al-Arish and Bir El-Abd were 20.7, 16.1, 53.4 and 13.9 μSv. That is one individual at risk due to the radiation exposure of naturally occurring radionuclides in 50.8, 84.7, 8.7 and 85.3 years for these cities, respectively. The results are compared with those from different areas in Egypt and in various countries

    For decades, Egypt has tried to increase its agricultural area through reclamation of desert land. The significance of land reclamation goes beyond the size of the reclaimed area and number of new settlers and has been important to Egyptian agricultural policies since the 1952-revolution. This...... villages, and lack of good schools and other public services may cause families to split up. For some, however, resettlement in the new lands entails new social and economic possibilities. The paper concludes that while land reclamation may not be ecologically or economic sustainable, the new lands provide...

  8. Egypt at the crossroads.

    1992-01-01

    Egypt is the location of the 1994 International Population and Development Conference. Conditions in Egypt due to expected population growth rates are anticipated as headed for "ecological breakdown." There is loss of prime agricultural land to urban expansion and difficulties in providing employment and vital services. The fertility decline to 4 children/family is still inadequate to meet resource needs; a 2-child family norm must be adopted because the country can barely meet the needs of 90 million people. Cairo is becoming a mega-city of squatter settlements and slums. Population densities approach 140,000/sq. kilometers. The family planning (FP) program receives top political support. The contraceptive prevalence rate has risen to just over 50%, a 10% increase since 1988. Egypt is the first Muslim country to surpass the 50% mark. Credit for this accomplishment is given to public information and education campaigns to reduce family size, expansion of maternal and child health services and FP, the cooperation of Muslim clerics, and better educated women. Nongovernmental organizations have played an active role in FP. The future challenge is to improve services and outreach and keep up with demand. Attitudes in rural areas have changed, so that desiring children to help with farm work is the exception. Progress on arresting environmental destruction has not been as successful. There are still poor irrigation practices. The breadbasket the Nile River sustained no longer exists; Egypt is a net importer of food. Water shortages and water quality limit productivity. 57.2 billion cu. meters out of 58.4 billion cu. meters of freshwater available from the Nile River are used primarily for irrigation of the 17.6 million hectares of agricultural land along the river and its delta. Salts have polluted the river from fertilizers and pesticides and municipal and industrial wastes. Industrial dumping is illegal, but continues. Treatment plants are inadequate and water pipes

  10. Organ transplantation in Egypt.

    Concern has increasingly been expressed about the growing number of reports of medical personnel participating in the transplantation of human organs or tissues taken from the bodies of executed prisoners, handicapped patients, or poor persons who have agreed to part with their organs for commercial purposes. Such behavior has been universally considered as ethically and morally reprehensible, yet in some parts of the world the practice continues to flourish. The concept of justice demands that every person have an equal right to life, and to protect this right, society has an obligation to ensure that every person has equal access to medical care. Regrettably, the Egyptian system does not legally recognize brain death and continues to allow the buying and selling of organs. For more than 30 years in Egypt, the ability to pay has determined who receives an organ and economic need has determined who will be the donor. As transplant professionals, it is important that we advocate on behalf of all patients, potential recipients, and donors and for those who are left out and not likely to receive a donor organ in an economically based system. Current issues associated with this debate are reviewed and recommendations about how to address them in Egypt are discussed. PMID:20929113

    The Neoproterozoic Gabal Abu Diab pluton is a part of the Arabian Nubian shield (ANS) continental crust and located in the Central Eastern Desert (CED) of Egypt. It constitutes multiphase granitic pluton intruded into granodiorite and metagabbro-diorite rocks with sharp and nonreactive contacts. Based on field observations, colors, structural variations and petrographic investigations, this granitic outcrop consists of an inner core of two-mica granite (TMG) followed outward by garnet bearing muscovite granite (GBMG) and albite granite (AG). Petrographical study indicated that medium to coarse-grained TMG is dominated by K-feldspar (Or88-98), quartz, plagioclase (albite, An0-7), muscovite and biotite with hypidiomorphic texture. With exception the appearance of garnet and the disappearance of biotite the GBMG resembles the TGM, while AG is leucocratic without any mafic mineral. The main accessories are zircon, Nb and Ta-bearing rutile, columbite, ilmenorutile, ilmenite, magnetite and apatite. This mineralogical similarity and the existence of columbite group minerals (CGM) in all granitoids, indicates a cogenetic relationship. Microprobe analyses reveal that, besides the CGM, rutile and ilmenite are the main repository phases for Nb-Ta-Ti. Columbite-(Mn) exists as individual subhedral crystals (up to 100μm in size) or intimate intergrowth with Nb-bearing rutile and/or ilmenite. The CGM are represented mostly by columbite-(Mn) with Ta/(Ta+Nb) and Mn/(Mn+Fe) ratio ranging from 0.02-0.08 and 0.4-0.9, respectively suggesting extreme degree of magmatic fractionation. Rutile contains significant amounts of Ta (up to 4 wt.% Ta2O5) and Nb (up to 22 wt.% Nb2O5). Biotites are phlogopite-annite in composition (Ann47-60Phlog40-53,on average) and are enriched with AlIV that characterize peraluminous granites. Garnets contain 60-69 mol.% spessartine and 28-36 mol.% almandine where, the ratio of spessartine and almandine together exceeds 95 mole percent, similar to garnet occur

    2016-06-01

    In their recent paper, Farouk and El-Sorogy (2015) present a reconstruction of the Danian-Selandian relative sea-level changes for the Western Desert of Egypt and an interpretation of eustatic versus tectonic controls on the latter. However, the relative sea-level changes should be distinguished from the shoreline shifts (also for the purposes of inter-regional comparisons). From three alternative global curves, two confirm the authors' conclusions, although it is questionable whether these curves are suitable for the purposes of such an analysis. It cannot be excluded that the relative sea-level fall in the late Danian was caused by the same regional tectonic uplift that resulted in the hiatus at the Danian/Selandian boundary. More research (including quantitative palaeobathymetric modelling) is necessary to understand the relative importance of the eustatic and tectonic controls on the sea-level changes established in the Western Desert of Egypt.

    This report provides an overview of past and current efforts to control schistosomiasis in Egypt, describes recent trends, and analyzes factors responsible for changes in transmission. For the purpose of long-term planning and developing control strategies, the country has been divided into eight geographic zones: Suez Canal Zone, Sainai, Nile Delta, Guiza, Fayoum, Middle Egypt, Upper Egypt, and the High Dam Lake Zone. Overall control priorities are examined and the strategy for each zone is described. The most recent information on changes in epidemiologic patterns of schistosomiasis in Egypt is mentioned, as well as the introduction of newer therapeutic agents. Lastly, the role of outside funding agencies in supporting schistosomiasis control is examined. PMID:7058982

  16. Cadmium status in Egypt

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    It is inferred from these studies that releases of Cd are still increasing and it is recommended that measures must be taken to reduce emissions of cadmium. Any cadmium discharged into the Egyptian environment may move from one compartment to another at varying rates,resulting in an accumulation in compartments such as soils and biota. Such accumulation can be expected to increase with continued emissions,and attention should be given to all sources of cadmium, natural as well as anthropogenic especially in the industrial cities in Egypt. Cadmium present in sewage, as well as industrial effluent (also, other liquid and solid wastes) and sewage sludge will increase levels in soils and is xpected to contribute to dietary levels and body burdens. The current information indicates that such effects may have to be evaluated over long periods of time, possibly as long as 50 - 100 years.

  17. Effect of alteration processes on the distribution of radionuclides in uraniferous sedimentary rocks and their environmental impact, southwestern Sinai, Egypt

    International Nuclear Information System (INIS)

    The contents of natural radionuclides in various types of sedimentary rocks in Um Bogma Formation and base of El Hashash Formation were determined by gamma-ray spectrometry. Three types of lower Carboniferous sedimentary rocks were investigated; sandstone (El Hashash Formation), dolostone and argillaceous sediments (Um Bogma Formation). The alteration processes are dolomitization, dedolomitization, karstification and lateritization. The specific radioactivity of 238U, 226Ra, 232Th and 40K determined in different samples, indicate that 238U and its decay products contribute primarily to the high natural radioactivity of rocks. The maximum concentration of 238U reached up to 2129.36 ppm in argillaceous sediments. The average concentrations of determined radionuclides (238U, 226Ra, 232Th and 40K) are 8.34 ppm, 7.88 ppm, 4.68 ppm and 0.3%, respectively in sandstone. In dolostones the average concentrations are 418.69 ppm, 808.75 ppm, 3.14 ppm and 0.29%, respectively. For argillaceous sediments are 276.88 ppm, 419.49 ppm, 11.47 ppm and 0.93%, respectively. The 238U/226Ra ratio in sandstone ranges between 0.89 and 1.25, while in dolostones and argillaceous sediments are 0.27-2.63 and 0.27-1.83, respectively. These variations in the concentrations of radioelements and their ratios are due to the action of the alteration processes affected these different sedimentary rocks in different times. Environmentally, the Raeq in dolostones and argillaceous sediments exceeds the permitted limits, while in the sandstone samples; it is within the permissible levels. (author)

  18. Behavior and environmental impacts of radionuclides during the hydrometallurgy of calcareous and argillaceous rocks, southwestern Sinai, Egypt

    International Nuclear Information System (INIS)

    The hydrometallurgy of radionuclides means getting the radioelements from the rocks into solution by leaching, getting the radionuclides from the solution by extraction process, and then precipitation of the desired elements to obtain concentrate. The follow-up of the radionuclides during these processes is the main target of this work to identify the identity of the original samples, pregnant solutions (leachates), residuals and the concentrate. Six samples were chosen to achieve this work. The leaching process was carried out under the conditions; 20–30% acid (H2SO4) concentration, 1:3 solid/liquid ratios, 60 min stirring time at room temperature. The activity concentrations of 238U, 235U, 234U, 226Ra, 214Pb, 214Bi, 232Th and 40K were measured in the original samples, residuals and U-concentrate (Bq/kg), and leachates (Bq/ℓ). The results indicate that, the radionuclides before 226Ra in the 238U decay series are more leachable (released) than those from 226Ra to 214Bi in the order; 234U>238U=235U ≫ 226Ra>214Pb>214Bi. 232Th and 40K are immobile under the present conditions. The radiological hazards of natural radioactivity in the original samples, leachates, residuals and U-concentrate were calculated and compared with the internationally recommended values and were found to be much higher than the world average values. - Highlights: ► Original rocks, leachates, residuals and concentrate were studied. ► Radionuclides concentrations were examined through different phases. ► Radionuclides are more leachable before than that after 226Ra series. ► Radiological hazards were compared with the international values. ► Cautions should be taken in considerations during mining process.

    2009-01-01

    Geological, petrological and geochemical studies indicated that there are two distinct types of granitoid rocks: older quartz diorites to granodiorite assemblage and younger granitoids, the latter occurring in two phases. The older granitoids have a meta-aluminous chemistry and a calc-alkaline character, with high MgO, Fe2O3, TiO2, CaO, P2O5, Sr and low SiO2, K2O, and Rb. Their major and trace elements data, together with low 87Sr/ 86Sr ratios (0.7029±0.0008) are indicative of I-type affinities. The second- and third-phase granitoids range from calc-alkaline to alkaline, respectively. The second-phase granitoids have a peraluminous chemistry and high Sr, Ba, CaO, MgO, Al2O3 and Ti2O and low SiO2, K2O, Nb, Y and Rb relative to the third-phase granitoids. The corundum normative nature and field observations suggested that it was formed by partial melting of the lower crust. The third-phase granitoids are alkaline in nature and characterized by higher SiO2, Rb, Y, Nb and lower MgO, Sr and Ba values than the younger granitoids (phase II). They are A-type granitoids which were generated from below or within the existing continental crust.

  2. Distribution and environmental impacts of some radionuclides in sedimentary rocks at Wadi Naseib area, southwest Sinai, Egypt

    International Nuclear Information System (INIS)

    The present study examines the natural radioactivity in some sedimentary rocks and their associated environmental impacts at Wadi Naseib area. Exposure rate (ER), dose rate (DR), radium equivalent activity (Raeq), external hazard index (Hex), internal hazard index (Hin) and radioactivity level index (Iγ) were calculated. Wadi Naseib area is covered with sedimentary rocks of early to late Paleozoic age. These rocks are classified into two types: mineralized and non-mineralized sediments. The radiometric investigations revealed that uranium and thorium contents reached up to 710 and 520 ppm, respectively, in the mineralized rocks. This was attributed to the presence of some secondary uranium minerals. All sediments had low values of eTh and K content. The exposure and dose rates exceeded public permissible values in the mineralized sediments. Exposure and dose rates were within the safety range for workers and the public in the non-mineralized sediments. The expected environmental impacts may be low due to the limited occurrence of U-mineralization and corresponding areas for radiation exposure. Some precautions and recommendations were suggested to avoid any possible environmental impacts from areas and/or raw materials of high intensity of natural radiation sources

    2001-02-01

    Thirty-three adult Damascus does (29 +/- 1.1 kg BW) were fed 0.6 kg per head per day of a concentrate diet plus ad libitum rice straw (Oryza sativa, control, R), or green acacia (Acacia saligna, A) or berseem clover hay (Trifolium alexandrinum, B). All treatment groups had free access to underground saline water containing 3600 ppm TDS. The DM intake was lower (p milk yield over 10 weeks and the milk composition (total solids, fat and protein percentages) were significantly different between the three groups; group B having the highest means and group R the lowest. These results suggest that supplemental feeding is required to enhance the productivity of goats in arid or semi-arid environments and Acacia saligna should not be used fresh in excessive quantities for extended periods.

  4. The Genesis of Ground Water in Sudr Area, South-West Sinai,Egypt, Using Environmental Isotopes and Hydrochemistry

    International Nuclear Information System (INIS)

    Sudr basin has an elevation varying from 50-450 m (+MSL) and catchment area of about 670km2. Carbonate rocks of Eocene age (Thebes formation) and Miocene age (Nukhul and Rudeis and Kareem formation) constitute the major geological units in the area. The faulted and or the un conformable nature of the contact between Esna shale and the carbonate rocks has essentially determined the occurrences of what is known as sudr springs. The origin of water in such spring is attempted for the first time. The hydrochemical and the environmental isotopes data have indicated that the water came from the dilution of the formation water having salinity of about 400 mg/L with fresh meteoric water having salinity of about 1260 mg/L. The isotopic data confirm the mixing nature between waters of different isotopic environments. The interpretation of the hydrochemical data via the computer code WATEQ has revealed that calcite dolomite, gypsum and halite are the main mineral species in the Sudr waters

    The crystalline complex and overlying sedimentary sequences in southern and central Sinai are highly dissected by numerous faults, shear systems, and dikes, hereafter referred to as discontinuities. Understanding the distribution of these discontinuities, their cross cutting relations, and the hydraulic gradient gives clues as to the distribution of water resources in the area. In the study area, extensional tectonics has been active as early as the Precambrian era as evidenced by the widely distributed dikes, bimodal volcanics, and dip-slip faults and shear zones of varying ages. These extensional tectonics and associated structural elements enhance the porosity and permeability of Sinai's basement and overlying sedimentary sequences. To investigate the impact of the discontinuities on groundwater flow, the following steps were conducted: 1) the spatial and temporal precipitation events over the basement complex were identified from TRMM data; 2) observations extracted from temporal change in backscattering coefficient in radar (Envisat ASAR radar scenes) were used to identify water-bearing discontinuities; 3) the discontinuities were delineated using false color images that were generated from ASTER, SIR C and band ratio images, 4) field observations, Very Low Frequency (VLF), magnetic investigations, and stable isotopic analyses for groundwater samples were then applied to refine satellite-based observations and selections, test the validity of our satellite-based methodologies for locating sub-vertical discontinuities, and decipher their role as conduits or barriers for groundwater flow. Findings include: (1) sub-vertical faults and shear zones and highly weathered chilled margins of sub-vertical mafic dykes are water-bearing and are conducive for groundwater flow; felsic dykes are massive (do not promote groundwater flow), (2) groundwater flow generally follows the topographic relief, but locally the flow is controlled by the discontinuities, (3

  7. Seismicity and seismic risk in and around Egypt

    International Nuclear Information System (INIS)

    Earthquake data in Egypt and its vicinity were compiled for the period between 2200 B.C. and 1980 A.D. Data earlier than A.D. 1900 were adjusted to historical documents of earthquake disaster, and the others (Period: 1901-1980) were arranged by consulting seismological bulletins of many observatories in the world and the seismological report of Helwan Institute. It was recognized from the above data that active seismic areas in and near Egypt are: (1) the northern part of the Red Sea, (2) the central part of the Red Sea, (3) the Levant Region, and (4) the north east part of Egypt. Seismic Risk maps for the area concerned, that is, regional distribution of maximum earthquake motion for some return periods were drawn up making use of the aforesaid data, attenuation models and the methods of extreme value fitting. The maps consist of the following two kinds: (1) The maximum particle velocity on the base rock, (2) The maximum acceleration on the ground. The return periods of these maps are 300 and 600 years, respectively. On the basis of these results, Egypt and its vicinity can be regarded as areas of moderate seismicity. (author). 14 refs, 9 figs

  9. Characteristics, spatial distribution and vertical profile of gamma-ray emitting radionuclides in the coastal environment of North Sinai

    International Nuclear Information System (INIS)

    Radionuclide concentrations of beach and dune sand from various sites in Al-Arish city and surrounding area, North Sinai, Egypt, were measured. The sampling sites included locations in the local harbor, Al-Arish valley and Zaranik protected area. The results indicate that the activities of the products of 232Th and 226Ra series in samples from the harbor and along the beach were higher than those from non-coastal sites. The activity concentrations of 232Th for beach sand ranged from 2.3 to 506.5 Bq/kg with an average of 83.4 Bq/kg, while that for dune sand ranged from 2.2 to 15.1 Bq/kg with an average of 6.4 Bq/kg. The average activity concentration of 226Ra for beach sand was 56.0 Bq/kg (2.9-261.5 Bq/kg), while that for dune sand was 6.5 Bq/kg (3.0-14.7 Bq/kg). The average activity concentrations of 40K for beach and dune sand were 88.1 Bq/kg and 178.4 Bq/kg, respectively. Six depth profiles in the harbor area were measured up to a depth of 1 m within more than two years. These sets of measurements allowed the determination of the migration rate of black sand to be 0.094 cm/day. Samples with the smallest grain size (<0.2 mm) were found to have the highest level of activities, which were attributed to their high content of black sand. No risk exists for public health based on the calculated effective dose equivalent and the recommended limit of 5 mSv/y. On the other hand, local children and adults may receive doses higher than this recommended limit in two locations in the Zaranik protected area according to a model developed in this study

    Egypt has suffered from a numerous of destructive earthquakes such as Aswan earthquake (1981, Mag 5.4) near the High dam, Dahshour earthquake (1992, Mag 5.9) near Cairo city and Aqaba earthquake (1995, Mag 7.2). As the category of earthquake damage includes all the phenomena related to the direct and indirect damages, the Egyptian authorities do a great effort to mitigate the earthquake disasters. The seismicity especially at the zones of high activity is investigated in details in order to obtain the active source zones not only by the Egyptian National Seismic Network (ENSN) but also by the local seismic networks. Studies of crustal movements in Egypt started as early as 1983 following the occurrence of Aswan earthquake in 1981. The first program for monitoring the crustal deformation has been started in Aswan area during the winter of 1983. Since the year of 1994 till now (currently 24 CORS stations), the geodetic observations by means of Space Technique (GPS) were applied instead of the terrestrial ones to cover some other regions of the country. These regions include Sinai, Gulf of Suez, Greater Cairo, Aswan and the Middle part on the River Nile. Data adjustment and analysis of the repeated GPS campaigns from the different networks prevailed significant movements which may help in more understanding the geodynamics of these regions. In the meantime, GPS measurements of crustal motions for 189 sites extending east-west from the Caucasus Mountains to the Adriatic Sea and north-south from the southern edge of the Eurasian plate to the northern edge of the African plate were carried out to Estimate the plate motions at stations located at different plates. From the previous results, we could find there are some correlations between the computed surface deformation and the earthquake occurrences in Local and regional scales. In the regional scales, the Hellenic arc is the region which shows very well this correlation. While in the Local scales, there are some

  13. Measurements of environmental radon-222 concentration in indoor and outdoors in Egypt

    International Nuclear Information System (INIS)

    The major contribution to population exposure to natural radiation arises from the inhalation of the decay products of radon. Substantial surveys are being conducted by several investigators to estimate the indoor and outdoor exposure nationally in Egypt and to discover regional variations. In this work, radon concentration in the indoor and the outdoor air was determined using the can technique and employing CR-39 solid state nuclear track detectors. The range of 222Rn activity in this survey was 2-11 Bq.m-3 in Cairo, 0.81-6.3Bq.m-3 in Alexandria and Aswan and Sinai ranged between 3.6-15.2 Bq.m-3. Values of indoor and outdoor radon concentrations were found to vary with time of day, geographic location, season and height above the ground. (author)

    Full Text Available Female Genital Mutilation is widely practiced in Egypt as well as in big sections of the African continent. The tradition of mutilation of the female genital areas has been practiced over the course of many years in the country and has been attributed to being promoted by the Islamic religion in Egypt. The Islamic religion is the most widely practiced religion within Egypt and therefore is linked to being the main reason why the country possesses one of the highest prevalence rates of the practice within Africa, according to many surveys performed by many leading agencies and nongovernmental organizations that advocate for the abolition of the practice within the country. FGM as a social health concern has been realized as not possessing any health benefits for the women and young girls who are taken through the practice.

    This image of Alexandria was taken by astronauts on board the International Space Station in December 2000 using an Electronic Still Camera. A wider-angle view (STS088-739-90) taken from the Space Shuttle in December 1998 is available for context. Alexandria (Al Iskandariya) occupies a T-shaped peninsula and strip of land separating the Mediterranean from Lake Mariout. Originally the town was built upon a mole (stone breakwater) called Heptastadium, which joined the island of Pharos (see referenced website, below) to the mainland. Since then sedimentary deposits have widened the mole. Since 1905, when the 370,000 Alexandrians lived in an area of about 4 sq km between the two harbors, the city (population 4 million; see referenced website, below) has grown beyond its medieval walls and now occupies an area of about 300 sq km. The Mahmudiya Canal, connecting Alexandria with the Nile, runs to the south of the city and, by a series of locks, enters the harbor of the principal port of Egypt (note ships). The reddish and ochre polygons west of Lake Mariout are salt-evaporation, chemical-storage, and water-treatment ponds within the coastal lagoon.

    The aim of this study was to measure concentrations and distributions of natural radionuclides occurring mentary rock samples from Eastern Desert (Um El-Huetat), Nile Valley (Gebel Owina) and from southwest Sinai (Wadi Ghweiba) were measured using a high-purity germanium detector. The samples under investigation (clay, shale and sandstone) were used as raw materials in the construction industry (bricks, ceramics, cement, fillers, etc.). Though the sediments of Egypt have already been investigated in the geological and mineralogical aspects, it is necessary to investigate the natural radioactivity in order to complete their classification. The average concentration values of 226Ra, 232Th, 40K in the surveyed samples were 47 ± 7,21± 5, 393±19 Bq.kg-1 (clay); 23 ± 5, 30 ± 6, 563 ± 24 Bq.kg-1(shale); and 17 ± 4, 14 ± 4, 299 ± 17 Bq.kg-1 (sandstone), respectively. All sediment samples have radium equivalent natural radionuclides present in the samples have been computed and compared with the global averages. In terms of the radiation safety, the natural radioactivity of the sediment in Egypt is below the recommended limits of the gamma dose rate. Therefore, they can be used for all kinds of public buildings.

    Asbestos has been recognized in Egypt since a long time as ancient Egyptians were using it in mummification. Mesothelioma in Egypt is mainly attributed to environmental origin with a high incidence of women and young adults affected. The incidence of mesothelioma is rising in Egypt. Epidemiological data for 635 malignant mesothelioma (MM) patients over 4 years in the third Millennium were collected from the National Cancer Institute (NCI), Cairo University and Abbassia Chest hospital. This number is more than four times the number diagnosed in the previous 11 years at NCI. A clinicopathological study was done for 100 malignant pleural mesothelioma (MPM) patients and showed that asbestos exposure and SV40 positivity were evident in 67% and 60% of cases, respectively. The median survival was 14.3 months and the 1 and 2 year survival rates were 60% and 27%, respectively. Evaluation of p53 and pRb immunohistochemically showed that pRb alteration was related to poor survival. Other biological prognostic factors such as EGFR, HER-2, glutathione S transferase (GST) and MDR were evaluated in 50 cases. Overexpression of EGFR was correlated with lack of clinical benefit and poor survival. GST potentiated the effect of EGFR on survival. The use of EGFR inhibitors may have a role in the treatment of MM. Asbestos in Cairo is a silent killer and measures toward eliminating it entirely or at least strictly controlling human contact with this dangerous carcinogen have to be taken in order to combat the coming epidemic of mesothelioma in Egypt.

    One of the major challenges in Egypt is the quality of education. Egypt has made significant progress towards achieving the Education for All and the Millennium Development Goals (MDGs). Many associations and committees as education reform program and education support programs did high efforts in supporting scientific thinking through the scientific clubs. The current state of astronomical education in Egypt has been developed. Astronomy became a part in both science and geography courses of primary, preparatory and secondary stages. Nowadays the Egyptian National Committee for Astronomy, put on its shoulders the responsibility of revising of astronomy parts in the education courses, beside preparation of some training programs for teachers of different stages of educations, in collaboration with ministry of education. General lectures program has been prepared and started in public places , schools and universities. Many TV and Radio programs aiming to spread astronomical culture were presented. In the university stage new astronomy departments are established and astrophysics courses are imbedded in physics courses even in some private universities.

    We analyze data from four GPS campaigns carried out between 1997 and 2002 on a network of 11 sites in the Suez-Sinai, the area of collision between the African and the Arabian plates. This is the key area to understand how and in which way Sinai behaves like a sub-plate of the African plate and the role played between seismic and geodetic (long term) deformation release. Our analysis shows that, on average, the Suez-Sinai area motion (in terms of ITRF00 velocities) matches African plate motion (NNR-NUVEL-1A model). However, the baseline length variations show transient deformations in Sinai and across the Gulf of Suez, reaching up a maximum value of about 1.5 cm in five years. Since current geodynamical models do not predict significant tectonic deformation in this area, we worked under the hypothesis that a contribute may be due to post-seismic relaxation. Under this hypothesis, we compared the baselines length variations with the post-seismic relaxation field associated with five major local earthquakes occ...

  10. Application of acid pugging and ferric salts leaching on West Central Sinai uraniferrous siltstone

    International Nuclear Information System (INIS)

    Application of acid pugging as well as leaching with ferric salts [FeC13 and Fe2(SO4)3] methods were investigated to overcome the solid - liquid separation problem normally faced in the conventional acid leaching methods. The applied methods minimized the leachant consumption and leaching time. In addition, the radium removal during the ferric salts leaching was actually taken in consideration to meet the environmental requirements. The acid pug leaching experiments were conducted by using 10 gm concentrated H2SO4 (equal to 200 kg/ton in the conventional leaching methods) upon 50 gm sample fractions. The pug was cured at 110oC for 1.5 hours. After curing, agitation leaching was performed with distilled water using a solid - liquid ratio of 1/3 for 6 hours at room temperature. The obtained leaching efficiencies were 95.7% for U, 97.3% for Cu and almost complete leaching for Mn. This method could also be applied at the mine sites on ores when making use of the sunlight for only a few hours a day. Bench scale studies proved that when applying the curing step in the sunlight for 4 hours using the other optimum operating conditions, U dissolution efficiency reached about 85.6% and about 86.6% for Cu but it was only about 25.7% for Mn. In comparison, application of ferric salts leaching on the ore proved that 93.3% and 37% U dissolutions were obtained when using 100 kg/t Fe2(SO4)3 versus FeC13, respectively. With respect to both Cu and Mn leaching efficiencies, it was found that higher recoveries were obtained when using FeC13 than when using Fe2(SO4)3. Tests were performed to improve the poor uranium leaching efficiencies in the FeC13 leaching method by the addition of HC1 which acted as initiating reagent. The results indicated that by adding 40 kg/t FeC13 an improvement of the uranium leaching was obtained, 92.2%. (author)

  11. U-Pb ID-TIMS dating of igneous and metaigneous rocks from the El-Sibai area: time constraints on the tectonic evolution of the Central Eastern Desert, Egypt

    Augland, Lars Eivind; Andresen, Arild; Boghdady, Gamal Yehia

    2012-01-01

    This paper presents new ID-TIMS U-Pb zircon and titanite ages from the El-Sibai gneiss complex in the Eastern Desert of Egypt. The zircon data support previous studies, indicating that the protoliths of the gneissic (oldest) units in the area were emplaced during the East African orogeny, and do not represent an older pre-Neoproterozoic, reworked cratonic basement. The crystallization ages of three compositionally distinct orthogneiss protoliths are c. 685, 682 and 679 Ma, respectively. A U-Pb titanite age from one orthogneiss overlaps with the protolith age, indicating that the gneisses did not undergo post-magmatic high-temperature metamorphism. The gneissic textures of the rocks are therefore interpreted to reflect syn-emplacement deformation. This, and evidence for static amphibolite facies metamorphism in country-rock metavolcanics, lead us to conclude that the gneisses of El-Sibai do not represent an exhumed middle crustal gneiss dome, but are part of the island arc affined allochthon into which they were emplaced synchronously with NW-ward nappe translation. We also report ages from rocks cross-cutting the gneisses and the surrounding island arc affined assemblages that yield the hitherto youngest robust pre-Cretaceous intrusive ages in the Eastern Desert. The dated rocks are an anorthosite and a cross-cutting syenogranite giving ages of c. 541 and 540 Ma, respectively. We consider this late magmatic pulse to be anorogenic, most likely reflecting a separate extensional event involving asthenospheric upwelling and decompression melting of the mantle.

  13. Using the Global Navigation Satellite System (GNSS) data for Hazard Estimation in Some Active Regions in Egypt

    Sayed Mohamed, Abdel-Monem

    2016-07-01

    Egypt rapidly growing development is accompanied by increasing levels of standard living particular in its urban areas. However, there is a limited experience in quantifying the sources of risk management in Egypt and in designing efficient strategies to keep away serious impacts of earthquakes. From the historical point of view and recent instrumental records, there are some seismo-active regions in Egypt, where some significant earthquakes had occurred in different places. The special tectonic features in Egypt: Aswan, Greater Cairo, Red Sea and Sinai Peninsula regions are the territories of a high seismic risk, which have to be monitored by up-to date technologies. The investigations of the seismic events and interpretations led to evaluate the seismic hazard for disaster prevention and for the safety of the dense populated regions and the vital national projects as the High Dam. In addition to the monitoring of the recent crustal movements, the most powerful technique of satellite geodesy GNSS are used where geodetic networks are covering such seismo-active regions. The results from the data sets are compared and combined in order to determine the main characteristics of the deformation and hazard estimation for specified regions. The final compiled output from the seismological and geodetic analysis threw lights upon the geodynamical regime of these seismo-active regions and put Aswan and Greater Cairo under the lowest class according to horizontal crustal strains classifications. This work will serve a basis for the development of so-called catastrophic models and can be further used for catastrophic risk management. Also, this work is trying to evaluate risk of large catastrophic losses within the important regions including the High Dam, strategic buildings and archeological sites. Studies on possible scenarios of earthquakes and losses are a critical issue for decision making in insurance as a part of mitigation measures.

    Full Text Available Without exaggeration, Egypt Post (EP is the oldest and most honored governmental institute in Egypt. Its headquarters, located in Ataba Square in downtown Cairo, is considered a central and prominent place in Cairo and Egypt. Khedive Ismail unveiled the inauguration of the headquarters officially.However, sometime within its lifespan until 2005, Egypt Post (EP was considered one of the worst governmental institutes in Egypt from a quality of service point of view. In addition, EP had not been a member of the Pan African Postal Union (PAPU for almost 20 years simply because EP had not been paying its yearly membership. On the global level, EP was a modest Universal Postal Union (UPU member with no strong value. This decline and poor image was because of several reasons that added up to the then Egypt Post status.Only three years later, EP was ranked third worldwide in the UPU congress elections. In addition, EP became a member of the two most important committees in the UPU: The Investment Committee, and the Executive Committee. This marks the transformation of the Egypt Post from a modest member in the UPU to a prominent and distinctive one. EP was also unanimously voted by the African Postal Organization to chair the PAPU in 2008 and 2009 after years of absence. It was a classic case of turnaround in terms of organizational improvement, efficiency and quality service.The business world is always changing and developing, causing the development and increase of relatively new concepts. These concepts include international trade, outsourcing and offshoring, virtual offices and organizations and cyber crimes, increasing the need for national and global security. One particular pillar of business is developing the most at an extremely rapid pace. This pillar is ICT where CEOs, CTOs, Managers and even researchers are constantly trying to stay updated with this ICT advancement.

    There is much latitude between the requirements of Schnirelman's theorem regarding the ergodicity of individual high-energy eigenstates of classically chaotic systems on the one hand, and the extreme requirements of random matrix theory on the other. It seems likely that some eigenstate statistics and long-time transport behavior bear nonrandom imprints of the underlying classical dynamics while simultaneously obeying Schnirelman's theorem. Indeed this was shown earlier in the case of systems which approach classical ergodicity slowly, and is also realized in the scarring of eigenstates, even in the $\\hbar \\to 0$ limit, along unstable periodic orbits and their manifolds. Here we demonstrate the nonrandom character of eigenstates of Sinai-like systems. We show that mixing between channels in Sinai systems is dramatically deficient compared to random matrix theory predictions. The deficit {\\it increases} as $|\\log \\hbar|$ for $\\hbar\\to 0$, and is due to the vicinity of the measure zero set of orbits which never...

    Geoethics, is a new term that could be unknown in the Arab world,where its translation in Arabic language make some kind of problems,with special emphasis on Egypt; spreading this term and the importance of it to professionals and un professionals is not an easy task.Culture and awareness problems face us on dealing with it. In this working paper the researchers study two levels of educational samples, the first one is of young geo-scientists and the other one is of young people of different disciplines to make over view survey (monitoring the base level) about knowing geoethics and another survey after applying some lectures and workshops to the same samples to monitor the second level. The aim of the research is to find out how people will accept this term and its application and how we can spread it through community with different effective ways. In Egypt there are some kind of culture problems could affect on spreading of any new concept, these problems could be overcome by some scientific, social and culture recommendations, these recommendations could be applied in both Arab countries and African Countries with few modifications.

  17. A second look at western Sinai seif dunes and their lateral migration

    2008-01-01

    Tsoar et al. [Tsoar, H., Blumberg, D.G., Stoler, Y., 2004. Elongation and migration of sand dunes. Geomorphology 57, 293-302.] reported that seif dunes in the western Sinai Desert did not migrate laterally between 1973 and 1999. If the planform sinuosities of the dunes are removed by filtering, spatial averaging, or linear regression, however, it is evident that the dunes did, in fact, migrate laterally roughly 13??m during this 26-year period. The measured migration distance is 1-2 orders of magnitude greater than the rms co-registration error Tsoar et al. determined for the first and last air photos that were used to map the dunes. The western Sinai dunes provide another example demonstrating that linear dunes can migrate laterally, and they illustrate some of the difficulties in documenting systematic lateral motion. Lateral migration of a dune can be important geologically or geomorphologically, even where migration is too slow to detect from repeated topographic surveys. This article explains the wind conditions for the lateral migration of seif dunes in western Sinai and the possible wind occurrences that would not lead to such a migration.

  18. A tectonic model of the Sinai Peninsula based on magnetic data

    International Nuclear Information System (INIS)

    The present work deals with the tectonic position of the Sinai Peninsula based on the interpretation of magnetic data. A high-resolution magnetic survey was undertaken, combined with aeromagnetic data, GPS and seismic stress-tension analysis. The magnetic data was interpreted using the analytical signal, horizontal gradient, Euler and Werner deconvolutions and 2.5 dimensional magnetic modelling methods. The seismological focal mechanism and stress-tension forces have also been evaluated. We conclude that the structural trend N35°–N45° west reflects the most predominant tectonic force in the southern part of the Sinai Peninsula, with a secondary N45°–N65° east tectonic trend. Interestingly, this situation is reversed in the northern part of the peninsula. The depth of the basement rocks ranges from zero at the southern end to more than 4 km below sea level at the northern end of the studied area. Furthermore, we found that the depth of the basement rocks increases from east to west, which is consistent with available well log data. This reflects a source of stress situated in the south that is pushing in the NE direction. Correlating the seismological and GPS analysis has enabled the construction of a tectonic model for the Sinai Peninsula

    AIM: To explore the effect of Sinai san decoction on the development of non-alcoholic steatohepatitis induced by CCL4 combined with a fat-rich diet in rats.METHODS: Twenty-seven Sprague-Dawley rats were divided into three groups randomly: control group (n = 9),model group (n = 9) and treatment group (n = 9). The rats of model group and treatment group were given small dosage of CCL4 combined with a fat-rich diet, andthose of control group were given normal diet. After four weeks of fat-rich diet feeding, the rats of treatment group were given Sinai san decoction. The serum levels of aminotransferase and lipid were measured, and the pathology of livers was observed by HE staining after the rats were sacrificed at eight weeks.RESULTS: The rats' livers presented the pathology of steatosis and inflammation with higher serum levels of ALT and AST in the model group. In the treatment group the serum ALT and AST levels decreased significantly and were close to the control group. The hepatic inflammation scores also decreased markedly, but were still higher than those of control group. And the degree of hepatocyte steatosis was similar to that of model group.CONCLUSION: Sinai san decoction may ameliorate the hepatic inflammation of rats with steatohepatitis induced by small dosage of CCL4 combined with a fat-rich diet,but does not prevent the development of hepatocyte steatosis.

  20. Adaptation to climate change in desertified lands of the marginal regions in Egypt through sustainable crop and livestock diversification systems

    Environmental degradation resulting from current climate changes, including prolonged drought, land degradation, desertification, and loss of biodiversity, is presenting enormous challenges to achieve food security and eradication of poverty in the marginal regions (about 90%of the total area) of Egypt. In addition to the natural constraints of high temperature, wind erosion, sand dune movement, and recurrent drought, such regions are subjected to improper land and water management. Moreover, there is a lack of knowledge, technologies, and experiences to match with the current severe climatic changes. There is a great need for establishing sustainable integrated ecosystem rehabilitation and management programs to overcome such problems in the marginal areas, particularly in the Sinai Peninsula due to its strategic and social importance. A series of research and development programs have been conducted in 2006 to im-prove the livelihoods of smallholders through enhancing the efficient management and utilization of local resources that can cope with the drastic changes of climate in the Sinai Peninsula. An integrated livestock/salt-tolerant fodder crop system was introduced, in 2010 by the project teamwork of Desert Research center, Egypt, to many smallholders in the South Sinai region, where studies were conducted at both the general research and individual farmer levels. The most important results were:(1) adoption of the most salt-tolerant genotypes of three forage crops:pearl millet (Pennisetum glaucum L.), sorghum (Sorghum bicolor), and Sudan grass (Sorghum sudanense (Piper) Stapf.); two cereal crops (triticale and barley);and two oil crops:safflower (Carthamus tinctorius) and Brassica (Mustard). Alfalfa (Medicago sativa L. and Medicago arborium), cowpeas (Vigna sinensis L.), fodder beets (Beta vulgaris L.), clumping desert bunchgrass (Panicum turgedum), ryegrass (Lolium perenne) Ray grass, forage shrubs (Kochia indica, Atriplex num-mularia, Sesbania sesban L

    Geller, Stephen A

    2008-08-01

    How did the education of surgical pathology, and pathology in general, differ at Mount Sinai? Passing the examination of the American Board of Pathology was never the focus of the department. Learning criteria or quoting references was de-emphasized, but mastery of macroscopic pathology was required, supported in both word and action by two brilliant surgical pathologists, Otani and Kaneko, and by two extraordinary medical pathologists, Klemperer and Popper. Meticulous microscopy emphasized pattern rather than reliance on lists of discrete features. Otani developed a regular "problem case" meeting for a community of pathologists, made up of alumni and other interested pathologists, as well as active department members. These monthly sessions provided the highest level of "continuing medical education." Otani and Kaneko unequivocally believed in learning from cases, and Mount Sinai residents were fortunate both in the one-to-one teaching and in the wealth of material, in all systems, that came to surgical pathology. Outstanding pathologists who came from Mount Sinai settled throughout the country and provided the highest level of diagnoses, but, with the exception of Bernard Wagner, Emanuel Rubin, Fiorenzo Paronetto, Richard Horowitz, Michael Gerber, Marc Rosenblum, Bruce Wenig, Jaishree Jagirdar, Swan Thung, Cesar Moran, Hideko Kamino, Philip LeBoit, Alberto Marchevsky, and others, there were relatively few academic leaders. Otani and Kaneko did not have national reputations. Klemperer, although world renowned, was relatively unassuming, and his disciples numbered almost as many nonpathologists as pathologists. Popper did establish a major center for liver pathology, with students coming from around the world, but did not particularly promote general surgical pathology. Can the Mount Sinai approach still be applied? The decline in the numbers of autopsies performed, the demands for rapid turnaround time, the de-emphasis of gross pathology as newer technologies (eg

  5. Nuclear desalination in Egypt: activities and prospects

    International Nuclear Information System (INIS)

    The main source of freshwater resources in Egypt is the River Nile. The Egyptian share of the Nile water was limited to 55.5x109 m3/year in the Nile Water Treaty concluded with Sudan in 1959. Due to the rapid population growth, the annual per capita freshwater resources declined from 2560 m3 in 1955 to 970 m3 in 1995. Consequently, desalination plants of various sizes and technologies have been introduced to Egypt in the past three decades. The Egyptian desalination inventory increased from less than 2000 m3/day in 1970 to almost 175000 m3/day in 1997, of which 54% was seawater desalination. The energy-intensive seawater desalination technologies are expected to play an increasing role in mitigating future potable water deficit in Egypt. Egypt has been considering for a number of years the introduction of nuclear energy to meet the combined challenge of increasing electricity and water demand on one hand and the limited primary energy and water resources on the other hand. In this regard, Egypt has been carrying a number of national, regional and international activities. This paper presents an overview of the Egyptian activities in the field of nuclear desalination including, feasibility studies and Research and Development activities. The results of recent studies are presented regarding: quantification of seawater desalination market in Egypt and preliminary economic assessment of potable water production by various combinations of energy sources and desalination processes proposed for El-Dabaa site.

    Bogoch, R.; Magaritz, M.

    1983-09-01

    Diabase dykes containing spherical patches of carbonate intrude the Tarr albitite complex of SE Sinai. The morphology of these dykes indicates a highly gas-charged magma. Petrographic evidence points toward equilibrium during cooling of immiscible carbonate ocelli and silicate matrix. Dolomite is the main component of these ocelli, which are geochemically and isotopically similar to carbonatite. However, the low total REE content, and the presence of considerable marble in the country rock, suggest a process of stoping and melting of carbonate, followed by the “in situ” development of silicate-carbonate immiscibility.

    We measured the electroencephalogram (EEG) of young students in the relaxed state and in the state of the mathematical activities. We applied the detrended fluctuation analysis and Kolmogorov–Sinai entropy (KSE) in the EEG signals. We found that the detrended fluctuation functions follow a power law with Hurst exponents larger than 1/2. The Hurst exponents enhanced at all EEG channels in the state of mathematical activities. The KSE in the relaxed state is larger than those in the state of the mathematical activities. These indicate that the entropy is enhanced in the disorder state of the brain.

    2012-12-01

    Full Text Available Egypt has limited water resources, and it will be under water stress within the year 2030. Therefore, Egypt should consider the natural and non-conventional water resources to overcome such problem. Rain harvesting is one solution; but not all; particularly on the north coast by the Mediterranean Sea and the Red sea. In this paper, the rainwater issue is reviewed and discussed in terms of the quantities and distribution at different selected areas in Egypt. The amount of rain falls at different location in Egypt was collected for a period of 16 months. The data indicated that rainfall in Egypt is very scarce, with an annual average of 12 mm and ranges from 0 mm/year in the desert to 200 mm/year in the north coastal region. The maximum total amount of rain does not exceed 1.8 billion m3per year. However, the average annual amount of rainfall water that is effectively utilized for agriculture purposes is estimated to be 1 billion m3. Harvesting pilot plant was constructed and implemented in Alexandria directly on the Mediterranean Sea. The harvested rain was used for irrigation and treated for drinking. It was, therefore, recommended to develop sustainable catchments at appropriate locations in the rain-fed areas at the north coast as well as cost effective grafting of the indigenous technologies with the innovative techniques.

The activities of the 232Th and 238U series in soil samples from two locations in harbor area and a location ∼ 3 km east the harbor were higher than those from other sites, with activities of 81.610.7, 50.6 ± 0.5, and 24.8 ± 0.4 Bq/kg 228 ,for 'Rn and 98.9 ± 1.3, 67.2±1.1, and 52.2±0.8 Bq/kg for 8Ac. The average contents for the other sites were 8. 7.2 and 7.5 ± 6.7 Bq/kg for 222Rn and 228Ac, respectively. No significant difference in the 40K activity was found between these two groups. The measured depth profiles in the site with the highest activity are studied. Samples with the smallest grain size (<0.2 mrr) were found to contain the highest level of activities, due to its high content of black sand

    2012-01-01

    Full Text Available Although Egypt has already reached the water poverty limit, it possesses a high potential of brackish groundwater available from different aquifers. All Arab countries lie in the best sun-belt region in the world and Egypt has the highest number of sun hours all year round. Solar energy for groundwater desalination is an independent infinite energy resource; it has low running costs and reduces the contribution of greenhouse gases (GHG to global warming. Perfect meteorological conditions and land space are available in remote areas, where solar desalination could supply freshwater for drinking, industry, and for greenhouse agriculture. The present study uses Geographic Information System(s (GIS as a spatial decision support tool to select appropriate sites in Egypt for groundwater solar desalination. Solar radiation, aquifer depth, aquifer salinity, distance from the Delta and the Nile Valley, incidence of flash floods, sand dunes, rock faults, and seawater intrusion in the North Delta, are the criteria that have been taken into consideration in the process of analysis. A specific weight is given to each criterion according to its relative influence on the process of decision making. The results from the application of the presented methodology determine the relative suitability of sites for groundwater solar desalination. These sites are ranked in descending order to help decision-makers in Egypt. The results show that groundwater solar desalination is suitable in remote regions on the North Western Coast, on the North Sinai Coast, and at the Southern Oasis, for reducing greenhouse gases and that it is particularly useful for poor communities suffering from polluted water.

  16. Radiopharmaceuticals production activities in Egypt

    International Nuclear Information System (INIS)

    Applications of radiopharmaceuticals and labelled compounds in the field of nuclear medicine in Egypt have increased so rapidly in the last few years. At present, a large number of hospitals are utilizing these radioisotopic techniques for both diagnosis and treatment. The following production activities are taking place in the Egyptian Radioisotope Production laboratories. By utilizing the research reactor a large number of radioisotopes which find wide applications in nuclear medicine were produced, such as iodine-131, phosphorus-32, sodium-24, potassium-42 and molybdenum-99 / technetium-99m generators. Gallium-67, indium-111 and iodine-123 will be produced locally after installation of the cyclotron at the end of 1998. A large number of Tc-99m based kits for diagnostic medical applications have been produced. Also, many radiopharmaceuticals labelled with iodine-131 were produced. The radioisotope production laboratory is able to supply many hospitals with the radioimmunoassay kits of the thyroid related hormones (T4, T3 and TSH). Research and development activities are taking place in the field of monoclonal antibodies and tumor markers with special consideration of AFP, CEA, PSA and βhCG. (author)

  17. Egypt's disarmament initiative

    Energy Technology Data Exchange (ETDEWEB)

    Fahmy, M.N. (United Nations, New York, NY (UN))

    1990-11-01

    On April 16, 1990, President Mubarak of Egypt proposed to the UN that all weapons of mass destruction be prohibited in the Middle East. The proposal arises from a conviction that the very presence of such weapons in the region is a security threat not only to the Middle East but also to international peace and security one which exacerbates an already tenuous and unstable situation. Egypt believes that creating an effective zone would reduce tension and generate impetus to resolving political conflict in the region, because it would exemplify the readiness of all countries to take into account the security concerns of others. Egypt's leaders are well aware that as long as political strife prevails in the Middle East, the obstacles to concrete disarmament measures are daunting. However, the potentially catastrophic consequence of yet another outbreak of hostilities drove them to seize the initiative.

    Although Egypt's budget deficit is far above the level found in other low-middle-income countries, the inflation rate in Egypt has never been very high. This is because the country has managed to finance these budget deficits by resorting to an inflation tax that, at 11 percent of GDP in 1987, constitutes a large share of total tax revenues. By contrast, conventional tax revenues come to only 17 percent of GDP. The authors report a large, underlying inflation-tax base - from which the Egyptia...

  3. Effect of Flash Flood in the Distribution of Radionuclides of Ground Water and its Environmental Impacts, Wadi Naseib, Southwestern Sinai, Egypt

    International Nuclear Information System (INIS)

    Groundwater can either be extracted from bedrock (drilled wells) or from soil aquifer (dug wells). This study was carried out on four dug wells in two successive years. Water samples were collected in April 2010 (after January 2010 flash flood) and April 2011 (with no flash flood). Samples were prepared for gamma spectrometry using hyper pure germanium detector. The results showed variations in the concentrations of 238U and its decay series nuclides, 232Th and 40K. The activity concentration of 238U was increased from 5 to 6 times after flash flood, while 232Th was increased around 10 times. The activity concentrations of 214Pb and 214Bi were 2 to 9 times higher in 2011 than in 2010 waters. The 234U/238U ratio is usually more than one. The analyzed groundwater samples recorded higher effective dose than the recommended reference for drinking water by WHO (0.1 mSv/y). ICRP recommendations set the limit for public exposure as an effective dose of 1.0 mSv/y. In this context, the effective dose of the samples collected in April 2010 were higher than the ICRP limit, while the samples of April 2011 were lower than this limit.

    In its 3,000 years History the surgery of the Old Egypt came on to an important development. Some of the antique instruments used in traumatology, the general surgery and in cosmetic-plastic operations, are in a scarcely modified manner employed for the same purposes in modern surgical interventions nowadays. The surgical diagnostics and therapy of that time is demonstrated by the surgical instruments stock being in the possession of the "Agyptisches Museum" of the "Staatlichen Museen zu Berlin". The surgery of Egypt transferred its leading part to the prosperous medical schools of Greece at the late period of the Old Egyptian empire (1085-332 B.C.). Its surgical diagnostics and therapy depending on an empirical rationalism, the applied instruments but also its ethical attitude towards the patients have been one of the dedisive bases influencing the development of the surgery in the antiquity.

    In Egypt there is no doubt that chronic liver diseases are a major health concern. Hepatitis C virus (HCV) prevalence among the 15−59 years age group is estimated to be 14.7%. The high prevalence of chronic liver diseases has led to increasing numbers of Egyptian patients suffering from end stage liver disease (ESLD), necessitating liver transplantation (LT). We reviewed the evolution of LT in Egypt and the current status. A single center was chosen as an example to review the survival and mortality rates. To date, deceased donor liver transplantation (DDLT) has not been implemented in any program though Egyptian Parliament approved the law in 2010. Living donor liver transplantation (LDLT) seemed to be the only logical choice to save many patients who are in desperate need for LT. By that time, there was increase in number of centers doing LDLT (13 centers) and increase in number of LDLT cases [2,400] with improvement of the results. Donor mortality rate is 1.66 per 1,000 donors; this comprised four donors in the Egyptian series. The exact recipient survival is not accurately known however, and the one-year, three-year and five-year survival were 73.17%, 70.83% and 64.16% respectively in the International Medical Center (IMC) in a series of 145 adult to adult living donor liver transplantation (AALDLT) cases. There was no donor mortality in this series. LDLT are now routinely and successfully performed in Egypt with reasonable donor and recipient outcomes. Organ shortage remains the biggest hurdle facing the increasing need for LT. Although LDLT had reasonable outcomes, it carries considerable risks to healthy donors. For example, it lacks cadaveric back up, and is not feasible for all patients. The initial success in LDLT should drive efforts to increase the people awareness about deceased organ donation in Egypt. PMID:27115003

    The Integrated Human Futures Project provides a set of analytical and quantitative modeling and simulation tools that help explore the links among human social, economic, and ecological conditions, human resilience, conflict, and peace, and allows users to simulate tradeoffs and consequences associated with different future development and mitigation scenarios. In the current study, we integrate five distinct modeling platforms to simulate the potential risk of social unrest in Egypt resulting from the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile in Ethiopia. The five platforms simulate hydrology, agriculture, economy, human ecology, and human psychology/behavior, and show how impacts derived from development initiatives in one sector (e.g., hydrology) might ripple through to affect other sectors and how development and security concerns may be triggered across the region. This approach evaluates potential consequences, intended and unintended, associated with strategic policy actions that span the development-security nexus at the national, regional, and international levels. Model results are not intended to provide explicit predictions, but rather to provide system-level insight for policy makers into the dynamics among these interacting sectors, and to demonstrate an approach to evaluating short- and long-term policy trade-offs across different policy domains and stakeholders. The GERD project is critical to government-planned development efforts in Ethiopia but is expected to reduce downstream freshwater availability in the Nile Basin, fueling fears of negative social and economic impacts that could threaten stability and security in Egypt. We tested these hypotheses and came to the following preliminary conclusions. First, the GERD will have an important short-term impact on water availability, food production, and hydropower production in Egypt, depending on the short- term reservoir fill rate. Second, the GERD will have a very small impact on

    Nine fetuses and neonates from sheep and goats in Egypt were screened for pestiviruses using immunohistochemistry (IHC), virus isolation, and reverse transcription-polymerase chain reaction (RT-PCR). Two goat kids with typical border disease (BD) were positive for pestivirus infection by immunohistochemistry (IHC) using polyclonal anti-BDV serum but not when four different monoclonal antibodies (MAbs) were used. On inoculation in MDBK cells, a cytopathic bovine viral diarrhoea virus (BVDV) was isolated from one of the two kids. PCR amplification followed by sequencing of the 5'-UTR region confirmed it as BVDV subtype 1b. Although the circulating virus in Egypt is considered to be BVDV 1a, this report confirms the existence of BVDV 1b in addition to BVDV 1a. To our knowledge, this is the first report of isolation of a pestivirus from goats in Egypt and is probably the second report worldwide of a goat kid showing central nervous signs associated with border disease.

  16. Application of Environmental Isotopes in Hydrological Studies Along the River Nile Valley, Egypt

    International Nuclear Information System (INIS)

    This paper reviews some of the contributions of isotope techniques to better understanding hydrological problems in Egypt and the Nile basin. The stable isotope composition of precipitation shows considerable variations both in time and space since it is controlled by climatic factors. Surface waters became enriched in deuterium and oxygen-18 relative to their initial isotopic composition as losses by evaporation occur. The GNIP sampling stations at Entebbe and Addis Ababa, which are located at the source of the Nile River, present relatively depleted isotopic contents. Assuming that the central Africa runoff (White Nile downstream from Sudan) represents 30% of the natural discharge of Egypt, and the remaining 70% is derived from Ethiopia (Blue Nile), we obtain a composite depleted stable isotope composition of the river Nile reaching upper Egypt under natural conditions (before the construction of the Aswan High Dam). Stable isotopes were used to estimate the evaporation rate from Lake Nasser, based on the isotopic content of the lake water. The lake can be divided into two sectors: the first sector, with remarkable vertical gradient in O-18 and deuterium, and a second sector, characterized by a lower vertical isotopic gradient. In order to detect this effect, surface Nile water samples have been collected at Cairo after a heavy storm event covering all Egypt at the beginning of November 1994, characterized by very negative deuterium and oxygen-18 contents. The isotopic content of Nile water samples fluctuated and slightly changed with time. The variation of the bomb tritium response of the Nile has been reconstructed using a model based on the contents in the catchment areas of the Nile. Pre-bomb tritium content in the Nile was about 5 TU, reaching a maximum level during the early sixties of about 500 TU. At present the tritium level content of the Nile is about 6 TU. (author)

  17. The chemical evolution of Kurnub Group palcowater in the Sinai-Negev province - A mass balance approach

    Rosenthal, E.; Jones, B.F.; Weinberger, G.

    1998-01-01

    The chemical evolution of the Kurnub Group paleowater was studied starting from rainwater in recharge areas of the Sinai and along groundwater flowpaths leading to the natural outlets of this regional aquifer. This was achieved by investigating the chemical composition of groundwater, ionic ratios, degrees of saturation with common mineral species, normative analysis of dissolved salts and by modeling of rock/water interaction and mixing processes occurring along groundwater flow paths. The initial groundwater composition used is from the Nakhel well in Sinai. It evolves from desert rainwater percolating through typical Kurnub Group lithology in Sinai. This rainwater dissolves mainly gypsum, halite and dolomite together with smaller amounts of marine aerosol and K-feldspar. At the same time it precipitates calcite, SiO2, smectite and degasses CO2. Between the area of Nakhel and the northern Negev the chemistry of Kurnub Group waters is influenced by dissolution of halite and lesser amounts of gypsum of surficial origin in recharge areas, small amounts of feldspars and of dolomite cement in sandstones eroded from the Arabo-Nubian igneous massif of Sinai and organic degradation-derived CO2. Concomitantly, there is precipitation of calcite, smectite, SiO2 and probably analcime characteristic of sediments in continental closed basins. North of the Negev, the Kurnub Group fluids are diluted and altered by mixing with Judea Group aquifer groundwaters. On the E there is mixing with residual brines from the water body ancestral to the Dead Sea, prior to discharge into the Arava valley. Rock/water interaction indicated by NETPATH and PHREEQC modeling is in agreement with lithology and facies changes previously observed in the Kurnub Group sequence.

The initial groundwater composition used is from the Nakhel well in Sinai. It evolves from desert rainwater percolating through typical Kurnub Group lithology in Sinai. This rainwater dissolves mainly gypsum, halite and dolomite together with smaller amounts of marine aerosol and K-feldspar. At the same time it precipitates calcite, SiO2, smectite and degasses CO2. Between the area of Nakhel and the northern Negev the chemistry of Kurnub Group waters is influenced by dissolution of halite and lesser amounts of gypsum of surficial origin in recharge areas, small amounts of feldspars and of dolomite cement in sandstones eroded from the Arabo-Nubian igneous massif of Sinai and organic degradation-derived CO2. Concomitantly, there is precipitation of calcite, smectite, SiO2 and probably analcime characteristic of sediments in continental closed basins. North of the Negev, the Kurnub Group fluids are diluted and altered by mixing with Judea Group aquifer groundwaters. On the E there is mixing with residual brines from the water body ancestral to the Dead Sea, prior to discharge into the Arava valley. Rock/water interaction indicated by NETPATH and PHREEQC modeling is in agreement with lithology and facies changes previously observed in the Kurnub Group sequence.

  13. Gamma-ray measurements of natural radioactivity in sedimentary rocks from Egypt

    International Nuclear Information System (INIS)

    The aim of this study was to measure concentrations and distributions of natural radionuclides occurring in rocks. The activity concentrations (Bq·kg-1) of the naturally occurring radionuclides 226Ra, 232Th, and 40K in sedimentary rock samples from Eastern Desert (Um El-Huetat), Nile Valley (Gebel Owina) and from southwest Sinai (Wadi Ghweiba) were measured using a high-purity germanium detector. The samples under investigation (clay, shale and sandstone) were used as raw materials in the construction industry (bricks, ceramics, cement, fillers, etc.). Though the sediments of Egypt have already been investigated in the geological and mineralogical aspects, it is necessary to investigate the natural radioactivity in order to complete their classification. The average concentration values of 226Ra, 232Th, 40K in the surveyed samples were 47 ± 7, 21 ± 5, 393 ± 19 Bq·kg-1 (clay); 23 ± 5, 30 ± 6, 563 ± 24 Bq·kg-1 (shale); and 17 ± 4, 14 ± 4, 299 ± 17 Bq·kg-1 (sandstone), respectively. All sediment samples have radium equivalent activities ranging from 55 to 115 Bq·kg-1, lower than the limit set in the OECD Report (370 Bq·kg-1). The overall mean outdoor terrestrial gamma dose rates fluctuate from 28 to 55 nGy·h-1. The external gamma radiation dose due to natural radionuclides present in the samples have been computed and compared with the global averages. In terms of the radiation safety, the natural radioactivity of the sediment in Eygpt is below the recommended limits of the gamma dose rate. Therefore, they can be used for all kinds of public buildings. (authors)

  14. Classification of complex biological aging images using fuzzy Kolmogorov–Sinai entropy

    International Nuclear Information System (INIS)

    With the rapid advancement of biomedical imaging device technology, the role of image processing coupled with pattern recognition, which is the science of classification of objects into a number categories or classes, is increasingly becoming important for the study of biological and medical images. As a matter of fact, the term Bioimage Informatics has been coined in the community of bioinformatics to emphasize the essential application of computational methods in assisting life-science researchers in the quantitative analysis of large volumes of images. This paper presents the formulation of the Kolmogorov–Sinai entropy under the mechanism of fuzzy uncertainty as an effective image feature for complex pattern classification. In this study, the particular focus is on classifying biological images relating to aging. The performance of the proposed method was tested against several current challenging image datasets that are benchmarks for comparing image classification techniques for overcoming the limited capacity of existing automated biological image analysis. The results demonstrate the superiority of the use of the new image feature for classifying difficult image objects in current biology. (paper)

  15. Late Cretaceous - early Tertiary dextral transpression in north Sinai: Reactivation of the Tethyan Continental Margin

    Energy Technology Data Exchange (ETDEWEB)

    Moustafa, A.R.; Khalil, M.H. (Ain Shams Univ., Cairo (Egypt))

    1988-08-01

    Detailed photogeologic study and field checks indicate the North Sinai folds are associated with northwest-dipping upthrusts, especially on their southeastern steeply dipping flanks. These northeast-southwest-plunging folds include both large folded ranges (tens of kilometers long, e.g., Gebels Yelleq, El Maghara, and El Halal) and smaller folds (2-10 km long). The smaller folds have right-stepping en echelon arrangement and define six east-northeast elongated belts which were probably formed by right-lateral wrenching in Late Cretaceous-early Tertiary time. These belts are called the G, El Amrar belt, the G. El Mistan belt, the G. Um Latiya belt, the G. Falig belt, the El Giddi Pass-G. El Minsherah-G. El Burqa belt, and the Mitla Pass-G. Kherim-G. Araif El Naq belt. The existence of northwest-dipping upthrusts within and between these en echelon fold belts probably indicates the wrenching was convergent. The en echelon fold belts are proposed to overlie pre-existing deep-seated faults which could have been formed by the Late Triassic-Liassic rifting of north Africa-Arabia to form the southern passive continental margin of the Tethys sea. Mesozoic rocks thicken across these faults. Late Cretaceous-early Tertiary reactivation of these faults by dextral transpression probably resulted from the oblique movement between Africa and Eurasia to close the Tethys sea.

  16. Kolmogorov-Sinai entropy in field line diffusion by anisotropic magnetic turbulence

    International Nuclear Information System (INIS)

    The Kolmogorov-Sinai (KS) entropy in turbulent diffusion of magnetic field lines is analyzed on the basis of a numerical simulation model and theoretical investigations. In the parameter range of strongly anisotropic magnetic turbulence the KS entropy is shown to deviate considerably from the earlier predicted scaling relations (1992 Rev. Mod. Phys. 64 961). In particular, a slowing down logarithmic behavior versus the so-called Kubo number R >> 1 (R = (δB/B0) (ξ||/ξperpendicular), where δB/B0 is the ratio of the rms magnetic fluctuation field to the magnetic field strength, and ξperpendicular and ξ|| are the correlation lengths in respective dimensions) is found instead of a power-law dependence. These discrepancies are explained from general principles of Hamiltonian dynamics. We discuss the implication of Hamiltonian properties in governing the paradigmatic 'percolation' transport, characterized by R → ∞, associating it with the concept of pseudochaos (random non-chaotic dynamics with zero Lyapunov exponents). Applications of this study pertain to both fusion and astrophysical plasma and by mathematical analogy to problems outside the plasma physics.

  17. Subsurface faults detection based on magnetic anomalies investigation: A field example at Taba protectorate, South Sinai

    Science.gov (United States)

    Khalil, Mohamed H.

    2016-08-01

    Quantitative interpretation of the magnetic data particularly in a complex dissected structure necessitates using of filtering techniques. In Taba protectorate, Sinai synthesis of different filtering algorithms was carried out to distinct and verifies the subsurface structure and estimates the depth of the causative magnetic sources. In order to separate the shallow-seated structure, filters of the vertical derivatives (VDR), Butterworth high-pass (BWHP), analytic signal (AS) amplitude, and total horizontal derivative of the tilt derivative (TDR_THDR) were conducted. While, filters of the apparent susceptibility and Butterworth low-pass (BWLP) were conducted to identify the deep-seated structure. The depths of the geological contacts and faults were calculated by the 3D Euler deconvolution. Noteworthy, TDR_THDR was independent of geomagnetic inclination, significantly less susceptible to noise, and more sensitive to the details of the shallow superimposed structures. Whereas, the BWLP proved high resolution capabilities in attenuating the shorter wavelength of the near surface anomalies and emphasizing the longer wavelength derived from deeper causative structure. 3D Euler deconvolution (SI = 0) was quite amenable to estimate the depths of superimposed subsurface structure. The pattern, location, and trend of the deduced shallow and deep faults were conformed remarkably to the addressed fault system.

  18. Studying Of Naturally Occurring Radioactivity In Some Locations Of South Sinai

    International Nuclear Information System (INIS)

    Gamma spectrometry technique was used to determine the environmental radioactivity concentration in some locations of south Sinai over the extended region; Oion Moussa, Ras Sudr up to Hammam Pharaon to a distance of 75 km. Sand beach, sea water in addition to sulphated water and soil samples were collected over the extended 75 km2 area. Natural radionuclide; Ra-226, Th-232 and K-40, were measured using the high resolution gamma spectrometer. The specific activities of naturally occurring radionuclides in the collected samples were found to be respectively in the range of UDL-222, 16-198 and 26-206 Bq/Kg. The radium equivalent activity (Raeq) and hazards index due to the naturally occurring radioactivity were calculated and also the gamma absorbed dose rate in air (μGy/h) and the total annual effective dose (μSv/y) were estimated. The obtained results can be used as reference information to assess any changes in radioactive background level. It would be possible to state that, at the investigated sites and locations, the exposure dose to human is still with permissible levels to public and specially tourists to use these sites as good areas for recreation and rehabilitation due the presence of naturally underground sulphated water

    Full Text Available This work deals with the evaluation of the structural set-up of the southern part of Sinai Peninsula, Gulf of Suez and western part of Gulf of Suez from magnetic, gravity, and seismic data. The utilised techniques including the Least Squares separation method suggest NW, NE, and E-W trends. The trend analysis shows north 35°-45° west, north 15°-25° east and E-W which may be related to the Gulf of Suez and Red Sea stresses.The Euler deconvolution illustrates that the area is highly affected by these trends. Depths range from 1 km to more than 3 km below sea level and its magnetic susceptibility ranges between 1 to 3 SI units. The 2.5D magnetic modelling and analytical signal techniques confirm the depths to the magnetic sources deduced by the Euler method, whereas the depth to the basement rocks ranges between 0 km to about 3 km indicating that it is subjected to strong tectonic activities. In addition, two seismic sections (EG-31 and MP-70, compiled by the Egyptian General Petroleum Cooperation (EGPC, were interpreted together with a geologic cross section. The studied area may be divided into several major blocks along the Gulf of Suez area. It can be concluded that the sedimentary was affected by basement tectonics as revealed by the two seismic sections.

  20. Using Remote Sensing and Gis Techniques For Assessment The Environmental Changes in The Area Surrounding Suez Canal, Egypt

    International Nuclear Information System (INIS)

    Multi-temporal Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data were utilized in a Geographic Information System (GIS) to evaluate changes in landuse II and cover in the area surrounds the Suez Canal, Egypt. The area is bounded by the Great Bitter Lake from the south, El Qantara city from the north, Nile Delta from the west, and Sinai Peninsula from the east. The area witnessed a rapid development in the past three decades, and the environmental changes were very remarkable. The data collected by Landsat sensors, TM (1984) and ETM+ (2000) were used to conduct a change detection and landuse analysis over the area of study. Both images were spatially registered and band four (Near Infra-Red) was radiometrically normalized to eliminate the atmospheric and sun luminance variation. Band algebra techniques were implemented to generate a reflectance difference image. On the other hand, the images were classified with supervised (maximum likelihood) technique with the help of ground truth data to provide the landuse maps for 1984 and 2000 periods. These maps were converted to GIS environment and final landuse changes have been provided

  8. Naturally occurring radionuclides and dose assessment in some locations south Sinai

    International Nuclear Information System (INIS)

    Soil and sulphated water samples were collected from south west Sinai near Suez gulf (Abu Sweera and Hammam Pharaon sites). Naturally occurring radionuclides 226Ra, 232Th series and 40K were measured using a high resolution gamma ray spectrometry. Specific activity levels of the naturally occurring radionuclides were found to be respectively ranged over 150-2020, 5-120 and 15-70 Bq/kg for the different locations. Gamma absorbed dose rate (μ Gy/h), due to the natural radioactivity distribution, were calculated for all locations. It was found to be ranged over 1.31 E-3-9.78 E-1 μ Gy/h for both sites. The total annual effective dose (μ Sv/y) to man due to 226Ra sub-series, 232Th series and 40K was estimated and found to be ranged from 8.94 E-4 to 5.86 E-1 μ Sv/y. These calculations showed that the highest equivalent dose would be received by the body surface, skin, followed by breast then testes. The lowest equivalent dose would be received by gall bladder, pancreas and SI wall. Total effective dose to all organs, due to the three natural radionuclides for the location which has the highest specific activity, was calculated and it was 9.07 E-11 mSv/h and the total committed dose equivalent for the remainder tissues, Hcom due to all radionuclides, was calculated as 3.33 E-12 mSv/h

    Full Text Available The traditional approaches for bridges maintenance is proven to be inefficient as they lead to random way of spending maintenance budget and deteriorating bridge conditions. In many cases, maintenance activities are performed due to user complaints. The objective of this paper is to develop a practical and reliable framework to manage the maintenance and repair activities of Bridges network in Egypt considering performance and budget limits. The model solves an optimization problem that maximizes the average condition of the network given the limited budget using Genetic Algorithm (GA. The main tasks of the system are bridge inventory, condition assessment, deterioration using markov model, and maintenance optimization. The developed model takes into account multiple parameters including serviceability requirements, budget allocation, element importance on structural safety and serviceability, bridge impact on network, and traffic. A questionnaire is conducted to complete the research scope. The proposed model is implemented in software, which provides a friendly user interface. The results of the framework are multi – year maintenance plan for the entire network for up to five years. A case study is presented for validating and testing the model with Data collected from “General Authority for Roads, Bridges and Land Transport” in Egypt.

  10. Mercury Removal from Natural Gas in Egypt

    International Nuclear Information System (INIS)

    Worldwide natural gas is forecasted to be the fastest growing primary energy source. In Egypt, natural gas is recently playing a key role as one of the major energy sources. This is supported by adequate gas reserves, booming gas industry, and unique geographical location. Egypt's current proven gas reserves accounted for about 62 TCF, in addition to about 100 TCF as probable gas reserves. As a result, it was decided to enter the gas exporting market, where gas is transported through pipelines as in the Arab Gas pipelines project and as a liquid through the liquefied natural gas (LNG) projects in Damietta, and ld ku. With the start up of these currently implemented LNG projects that are dealing with the very low temperatures (down to -162 degree c), the gas has to be subjected to a regular analysis in order to check the compliance with the required specifications. Mercury is a trace component of all fossil fuels including natural gas, condensates, crude oil, coal, tar sands, and other bitumens. The use of fossil hydrocarbons as fuels provides the main opportunity for emissions of mercury they contain to the atmospheric environment: while other traces exist in production, transportation and processing systems

These aspects are all concurrently active, and all are maintained and coordinated through the Secretariat, the technical arm of NCDDP. The goal of the communications element, the focus of this discussion, is to teach, persuade, and change the behaviors of all Egyptian mothers of children under 3 years and other specific target groups, especially health personnel, pharmacists, mass media reporters, and decisionmakers involved with the management of diarrhea and dehydration programs. Data acquired through target audience research provides program planners with the most useful and valid information upon which to build a communication campaign. This holds true whether the activity is to select an appropriate logo to call attention to the campaign or to determine the most effective channels through which to communicate social messages. Regarding the logo, 4 designs were selected from among 10 submitted by independent artists and advertising agencies. Focus groups and brief interviews in public places on these 4 logos were carried out to determine audience response. Questioning the mothers who participated in focus groups helped project staff determine what amount of fluid a mother would find believable to give to a child with diarrhea. In addition, surveys showed that a 200cc packet of salts would be the most

    1996-12-31

    Though its contribution to the global Greenhouse gases emission is relatively small, Egypt has signed and ratified the United Nations Framework Convention on Climate Change (UN FCCC) and has been playing an active role in the international efforts to deal with such environmental challenges. Energy efficiency has been one of the main strategies that Egypt has adopted to improve environmental quality and enhance economic competitiveness. This paper highlights three initiatives currently underway to improve energy efficiency of the Egyptian industry. The first is a project that has been recently completed by OECP to assess potential GHG mitigation options available in Egypt`s oil refineries. The second initiative is an assessment of GHG mitigation potential in the Small and Medium size Enterprises (SME) in the Mediterranean city of Alexandria. The third one focuses on identifying demand side management options in some industrial electricity consumers in the same city.

  17. Policy aspects of electricity and the environment in Egypt

    International Nuclear Information System (INIS)

    Egypt is facing many challenges, most of which stem from the high population growth rate. Efforts to improve the standard of living require substantive development of Egypt's economic, technical, community, electricity and energy infrastructures. Over the past three decades, the electric energy demand has increased more than 15 fold, requiring development of sound national electric energy policies based on rational use of indigenous resources which are, unfortunately, limited. Realization of such policies faces a number of economic and social constraints, all of which need great efforts to overcome. Environmental considerations within Egypt's electric energy policies are focusing more attention on the degradation in environmental conditions, which is in line with growing public concern about this issue, both locally and internationally. An alarming increase in pollution levels in the urban areas of Egypt has necessitated the creation of new laws to curb pollution of the air and the environment, in addition to adhering to strict standards for effluents from thermal power stations.

    Recent research indicates that fertility transition is underway in Egypt. However, after experiencing a rapid decline since the 1980s, the fertility decline in Egypt seems to be stalling since the second half of the 1990s. Of late, it has been realized that the total family rate as the conventional measure is a poor indicator of fertility for populations undergoing rapid fertility transition. In particular, if childbearing is postponed and, subsequently, the mean age at childbearing increases...

  6. Neutron activation analysis for determination of selected trace elements responsible for immunity in foodstuffs and water in egypt

    International Nuclear Information System (INIS)

    Selenium (Se), zinc (Zn), magnesium (Mg), molybdenum (Mo) and vanadium (V) in 28 types of Egyptian common foodstuffs as well as drinking and irrigation water samples were determined using neutron activation analysis (NAA) and atomic absorption spectrometry (AAS). The samples were collected from 74 sites over 13 governorates as well as the Nile river, wells and tap water in the regions of the Nile Delta, Sinai, the east and west desert, and north and south Egypt. These trace elements were chosen according to international references, which show the close relationship of their deficiencies to immunity-related diseases. Calculation values of daily uptake per capita were made with the results of analysis. The results, as calculated per 100 g dry weight, showed that some Egyptian foods are rich in Se including such fish (0.94 μg), sesame (0.88 μg), beef meat (0.48 μg), instant tea (0.42 μg), mushroom (0.34 μg) and eggs (0.3 μg), whereas the vegetables contained less than 0.3 μg. Also, soybean, cabbage, beef meat and eggs were rich in Zn (8.0, 3.0, 2.0, 2.0 mg, respectively). At the same time, vegetables and fruits can be considered major sources for Mg, Mo and V for Egyptians International Recommended Dietary Allowance (RDA). We calculated a notable shortage of Se and Zn in Egyptian meals, whereas Mg, Mo and V were present in large enough amounts to satisfy the RDA. Water analyses showed that drinking or irrigation water provided safe levels of trace elements in most of the governorates, except desert regions like Sinai especially in the case of Taba, Nuweiba, Dakhla and Paris oases in New Valley whose tap water offered little Se and Zn. Therefore, we conclude that supplementation of all Egyptian diets with Se and Zn is very important in preventing heart and immunity diseases especially for those who live in the desert and depend completely on well water for drinking and irrigation. Similar recommendations have-already been implemented in the USA, Finland and

    As many industrial and third-world countries recover from the severe economic crisis of a global recession, they continue to struggle with its negative effect on their healthcare systems. Healthcare reform has become a leading policy agenda item for most countries. This is especially true for countries in the developing world who are struggling to allocate very limited resources to meet the growing health needs of their residents and the expectations of global health. In the late 1990s, the Egyptian government, in conjunction with the United States Agency for International Development, initiated a Health Sector Reform Program (HSRP) to completely reform the way healthcare was financed, organized and delivered with the intent to extend healthcare coverage to all of its citizens. Although some successes have resulted from the HSRP, Egypt's new government leaders will need to be informed on policies that may more effectively improve the health of the Egyptian population.

    The emerging evidence of the potentially clinicalimportance of occult hepatitis B virus (HBV) infection(OBI) increases the interest in this topic. OBI mayimpact in several clinical contexts, which include thepossible transmission of the infection, the contributionto liver disease progression, the development ofhepatocellular carcinoma, and the risk of reactivation.There are several articles that have published on OBI inEgyptian populations. A review of MEDLINE databasewas undertaken for relevant articles to clarify theepidemiology of OBI in Egypt. HBV genotype D is theonly detectable genotype among Egyptian OBI patients.Higher rates of OBI reported among Egyptian chronicHCV, hemodialysis, children with malignant disorders, andcryptogenic liver disease patients. There is an evidenceof OBI reactivation after treatment with chemotherapy.The available data suggested that screening for OBI mustbe a routine practice in these groups of patients. Furtherstudies needed for better understand of the epidemiologyof OBI among Egyptian young generations after the eraof hepatitis B vaccination.

  9. Economic study of rice irradiation in egypt

    International Nuclear Information System (INIS)

    The paper discusses the economics of rice irradiation and the effect of various parameters on unit processing costs. It provides a model for calculating specific unit processing costs by correlating known capital costs with annual operation cost and annual throughputs. It is intended to provide the investors with a general knowledge of how unit processing costs are derived. The investment criteria utilized for commercial evaluation were internal rate of return (I.I.R), pay back period (P.B.P), and average rate of return (A.R.R). The irradiation cost and the additional income are also discussed. The result of the analysis showed that the installation of an irradiation unit in Egypt would be economically feasible

  10. Geotechniques of landfill design in Egypt

    International Nuclear Information System (INIS)

    The remarkable pollution and the deteriorating environmental conditions in the capital city and other major cities in Egypt have created serious health problems and had great impact on social and economical development. This situation has urged the government to establish a new ministry for environment. The ministry put a national action plan to overcome all the local environmental problems. Among them, the tremendous amounts of solid wastes that are produced daily by the overpopulated cities used to be dumped in open areas causing a terrible unbearable pollution. The ministry has recently initiated several projects for solid and hazardous waste management and disposal to be executed according to the international standards. The Ministry of Environment has appointed a team of multidisciplinary experts to carry out the environmental impact assessment of site selection and the engineering design of landfills. I was fortunate enough to join the team as a geotechnical consulting engineer to review the design of the proposed landfills from the geotechnical point of view. The criteria for landfill design included the physical size, its proximity and access, topography, geotechnical and geological aspects, surface water, ground water hydrology, and future site development and land use. Several sites have been selected to start the project; in Nasr City, 15th of May City, and Assalam City, which are districts of Cairo, Abu-Zaabal in Kalubia Governrate, Shabramont in Giza, Shawa in Dakahlia, Borg El-Arab near Alexandria, two sites in Monofia, and another one in El-Katamia. The paper presents the studies carried out for site selection, geotechnical design, and the possible impact on the environment of the surrounding areas. The studies also included the hydro-geological conditions and the assessment of the ground water conditions in each site and the potential contamination. Socioeconomic measures and public participation in decision making were also taken into consideration

  14. Provenance of sedimentary kaolin deposits in Egypt: Evidences from the Pb, Sr and Nd isotopes

    Science.gov (United States)

    Baioumy, Hassan

    2014-12-01

    This work reports, for the first time, the Pb, Sr and Nd isotopes of the clay fractions (kaolin deposits in Egypt of different ages (Carboniferous and lower Cretaceous), localities (Sinai, Red Sea and Aswan), lithologies (flint and plastic) and clay minerals composition (pure kaolinite and mixture of kaolinite, illite and chlorite) to determine their source area compositions and examine the effect of provenance on their isotopic compositions. Measured (present day) and age-corrected Pb isotopes data (100 and 300 My for the Cretaceous and Carboniferous deposits, respectively) are more or less homogeneous in all deposits regardless of their ages, localities, and compositions. This, therefore, suggests that the Pb isotopes cannot be used as a tracer for source area compositions of these kaolin deposits. On the other hand, the studied kaolin deposits show variations in their measured and age-corrected Sr and Nd isotopes regarding to their ages and compositions. The Carboniferous illite-rich kaolin deposits in the Khaboba and Hasbar areas, Sinai have higher measured and age-corrected 87Sr/86Sr ratios (average of 0.715742 and 0.711156 for measured and age-corrected, respectively) compared to the non-illitic Carboniferous deposit at Abu Natash area (average of 0.70772 and 0.70769 for measured and age-corrected, respectively) and the lower Cretaceous deposits in all areas (average of 0.70827 and 0.70821 for measured and age-corrected, respectively). The Carboniferous kaolin deposits in the Khaboba and Hasbar areas also have lower 143Nd/144Nd ratios (average of 0.51206 and 0.51180 for measured and age-corrected, respectively) compared to the Carboniferous Abu Natash deposit (average of 0.51253 and 0.51231 for measured and age-corrected, respectively) as well as the lower Cretaceous deposits in all areas (average of 0.51248 and 0.51239 for measured and age-corrected, respectively). Initial εNd values are negative in the Carboniferous kaolin deposits in the Khaboba and

    This paper describes the development of the Flash Flood Manager, abbreviated as FlaFloM. The Flash Flood Manager is an early warning system for flash floods which is developed under the EU LIFE project FlaFloM. It is applied to Wadi Watier located in the Sinai peninsula (Egypt) and discharges in the Red Sea at the local economic and tourist hub of Nuweiba city. FlaFloM consists of a chain of four modules: 1) Data gathering module, 2) Forecasting module, 3) Decision support module or DSS and 4) Warning module. Each module processes input data and consequently send the output to the following module. In case of a flash flood emergency, the final outcome of FlaFloM is a flood warning which is sent out to decision-makers. The ‘data gathering module’ collects input data from different sources, validates the input, visualise data and exports it to other modules. Input data is provided ideally as water stage (h), discharge (Q) and rainfall (R) through real-time field measurements and external forecasts. This project, however, as occurs in many arid flash flood prone areas, was confronted with a scarcity of data, and insufficient insight in the characteristics that release a flash flood. Hence, discharge and water stage data were not available. Although rainfall measurements are available through classical off line rain gauges, the sparse rain gauges network couldn’t catch the spatial and temporal characteristics of rainfall events. To overcome this bottleneck, we developed rainfall intensity raster maps (mm/hr) with an hourly time step and raster cell of 1*1km. These maps are derived through downscaling from two sources of global instruments: the weather research and forecasting model (WRF) and satellite estimates from the Tropical Rainfall Measuring Mission (TRMM). The ‘forecast module’ comprises three numerical models that, using data from the gathering module performs simulations on command: a rainfall-runoff model, a river flow model, and a flood model. A

  20. Impact of solar energy cost on water production cost of seawater desalination plants in Egypt

    International Nuclear Information System (INIS)

    fossil fuel will increase electricity costs from conventional non-renewable sources. Solar thermal is cheaper (at a current price of 0.06 US$/kWh) than PV; however, PV is more appropriate for Egypt (for the time being) as it is more applicable to the smaller RO plant sizes found in Egypt (up to 5 MW; 10,000-15,000 m3/d product water capacity). We would expect that there will be a shift towards more centralized RO plants (larger size) in Egypt, to tackle the increasing water shortage, and this would then favor the adoption of solar thermal energy in the near future.

    2010-03-01

    Full Text Available This historical case study examines the rhetoric, action, and outcomes of educational policy reforms in Egypt during the first quarter-century of the presidency of Mohamed Hosni Mubarak. The findings are based on an extensive review of Egyptian government, international organization, and project documents as well as interviews with key stakeholders. The study focused on proposed and implemented changes in the organization and distribution of various governance and management functions across school/community, district/idarra, governorate/muddiriya, and national/central levels of the education system. During the period under review Egypt experienced movement though uneven toward increased decentralization, with calls for deconcentration of responsibility in 1981, Ministry of Education actions that restricted local decision-making authority in the 1990s, and some concerted efforts toward delegation and devolution of authority as well as responsibility after 2001. In terms of community participation, during this period there were calls for and actions toward implementing broader and deeper forms and degrees of involvement by parents, civil society, and businesses. We draw on the following concepts to analyze a develop an account of these developments: institutional framework, financial resources, system leaders' capacity and political will, civil society's leaders' capacity and political will, global dynamics, and the role of international organizations

    2002-04-01

    Fascioliasis, caused by Fasciola species, is a disease of herbivorous animals. It has a worldwide distribution in a large variety of grass-grazing animals as sheep, goats, cattle, buffaloes, horses and rabbits. In Egypt, donkeys and camels as well, are hosts for F. gigantica. Fascioliasis may occasionally affect man. Human infection causes serious hepatic pathological sequences that add to the already known threats to the liver of the Egyptian population. Two clinical stages are recognized in human fascioliasis. An acute stage coincides with the larval migration and worm maturation in the hepatic tissue, and a chronic stage coincides with the persistence of Fasciola worms in the bile ducts. Human infection with fascioliasis was very sporadic until the last three decades where clinical cases and outbreaks were reported. The estimated the number of people currently having fascioliasis to be 360,000 in Bolivia, 20,000 in Ecuador, 830,000 in Egypt, 10,000 in Islamic Republic of Iran, 742,000 in Peru, and 37,000 in Yemen. The total estimated number of people infected is 2.4 million in 61 countries and that the number at risk is more than 180 million throughout the world. Human fascioliasis has to be differentially diagnosed from some diseases as acute hepatitis, infection with other liver flukes as schistosomiasis, visceral toxocariasis, biliary tract diseases and hepatic amoebiasis. The parasitological diagnosis is based on identification of eggs in stool, duodenal contents or bile, also by the recovery of adult worm during surgical exploration, after treatment or at autopsy. However, the eggs may be present in very small number at irregular intervals, hence difficult to be found. Besides, the eggs may be transiently present in stool after ingestion of raw or undercooked liver from infected animals. The direct methods of diagnosing the egg are usually unsatisfactory. The symptoms may be present for several weeks before eggs are recovered in stool. Thus, the serologic

As I examine, political bloggers in this country (Islamist as well as secularist have pioneered new language forms and video styles in order to articulate an arena of political life they refer to as “the street.” Egyptian bloggers render visible and publicly speakable practices of state violence that other media outlets cannot easily disclose. In discussing the sensory epistemology informing these blogging practices, I give particular attention to the way traditions concerning the sonority of the Arabic language and the relation of written to spoken forms are exploited and reworked by some of Egypt’s most prominent political bloggers. I also examine how these language practices find a visual and aural analogy in the grainy cellphone video recordings found on many of Egypt’s political blogs. This paper analyzes such practices in relation to emergent forms of political agency and contestation in contemporary Egypt.

    2012-02-15

    During the last decade there have been several distinct activities and efforts with regards to future research in Egypt. Several institutions and capacities have been created. Although these capacities do not always meet high scientific standards, their results and studies offer important and well-grounded elements for future-oriented discussions and political decisions. Not least because of the Egypt revolt which started in January 2011 and the ongoing complex and conflicting societal struggles in Egypt the objective needs as well as the demand for systematic future thinking and future studies will very likely increase further. For that reason this report presents an overview about the context conditions, experiences and forms of future research in Egypt. The major challenges as well as the major issues are described. The main part is the description of the most important institutions, which are conducting future research, their projects and in addition two concrete projects, which try to practice Sustainable Development in different ways. Finally, several (self-)critical assessments and perspectives from selected experts of the future research community in Egypt will be presented.

  7. The electrical power equipment and services market in Egypt

    International Nuclear Information System (INIS)

    This report presents a market overview of the electrical power equipment and services in Egypt and describes the potential for Canadian suppliers to enter into joint ventures to establish local production facilities and transfer technology expertise. Between 1997 and 2001, energy consumption in Egypt increased by 17 per cent. Electricity demand is expected to rise rapidly due to population and economic growth. Plans are underway to add 8,000 MW of installed energy capacity to Egypt's current 15,200 MW by 2010. Priority will be on providing universal access to electricity and reliability in rural areas. Egypt is also taking part in many international projects to link its electricity grid with nearby countries. This report describes the key factors shaping market growth with particular reference to sector reform, and opportunities with actual and planned projects. The competitive environment was also discussed with reference to local capabilities, international competition, Canadian position, and a competitive advantage through Canadian government policies and initiatives. Recent legislation exempts foreign companies from corporation tax and from tax on income from movable capital for 5 to 10 years. A section of the report on public-sector customers described the several organizations that manage and approve electric power generation and transmission projects. Considerations for market-entry in Egypt were outlined. 29 refs., 3 tabs

    Full Text Available A leaching experiment was conducted using column techniques assessing efficiency of electrochemical process to reclaim saline-sodic soils. Soil material was collected from Sahl El-Tina plain, which located in North West coast of Sinai, Egypt. The experiment was designed as factorial randomized complete block and all treatments were replicated three times. Two 2.5 cm diameterx30 cm height mild stainless steel tubes were inserted into the soil matrix to serve as electrodes (i.e. cathode and anode. Distance between cathode and anode was 10 cm. Electrodes were supplied by a direct current (DC power supply; Volt ages of 0.3 or 9 Volt. Leaching was done using the intermittent method so as to add portions to the already saturated soil columns, and obtain leachates equal to the added portions. Pore volume 0.1 PV was used in the leaching processes which are equal 498.4 cm3, i.e. PV being volume of pores per column, thus 1 PV equals volume of pores (cm3 expressed as water quantity. Electric remediation increased ionic mobility and separated salts from soil. All treatments decreased soil EC and soil sodicity expressed as SAR and ESP. Results showed that 9 Volt treatment was more effective in decreasing the soil EC and soil sodicity than the other treatments. Efficiency of treatments were 9-Volt > 3-Volt > leaching alone (non-DC treatment. This study suggests that leaching using direct current (DC led to improvement of the chemical properties of saline sodic soils and required a short time to reclaim saline-sodic soils compared with leaching alone.

    Full Text Available AIM/BACKGROUND: Physician’s job satisfaction is a cornerstone for improving the quality of health care, and its continuity. To identify the extent of job satisfaction and explain its main components among physicians, together with finding out the main indicators for job satisfaction. METHODS: We randomly selected physicians from the Egyptian Ministry of Health and Population Hospitals. All participants were asked to fill a self administrated questionnaire which included data pertaining socio-demographic characteristics and job satisfaction regarding salaries/incentives, monitoring, administration system, management, career satisfaction, relationship with colleagues, social support, opportunities for promotion, and job responsibilities. Satisfied was defined as satisfaction of>60%. RESULTS: Two hundred and thirty eight physicians participated in this study; with mean age of 37.1+ 9.4 years, and 70.2% were males. Only 42.9% of the physicians’ reported job satisfaction. Relationship with colleagues was the most important component of satisfaction with mean of 81.3+19.6 while, salaries/incentives were the least one with mean of 16.2+ 14. The overall current satisfying domains were not significantly associated with marital status or educational level, however it was significantly associated with specialty. Neither age nor gender was significantly associated with the degree of job satisfaction. CONCLUSION: Our results call for paying more attention to improve physicians’ job satisfaction in Egypt, to meet needed higher standards in health care. [TAF Prev Med Bull. 2008; 7(2: 91-96

  12. Probabilistic earthquake hazard analysis for Cairo, Egypt

    Badawy, Ahmed; Korrat, Ibrahim; El-Hadidy, Mahmoud; Gaber, Hanan

    2016-04-01

    Cairo is the capital of Egypt and the largest city in the Arab world and Africa, and the sixteenth largest metropolitan area in the world. It was founded in the tenth century (969 ad) and is 1046 years old. It has long been a center of the region's political and cultural life. Therefore, the earthquake risk assessment for Cairo has a great importance. The present work aims to analysis the earthquake hazard of Cairo as a key input's element for the risk assessment. The regional seismotectonics setting shows that Cairo could be affected by both far- and near-field seismic sources. The seismic hazard of Cairo has been estimated using the probabilistic seismic hazard approach. The logic tree frame work was used during the calculations. Epistemic uncertainties were considered into account by using alternative seismotectonics models and alternative ground motion prediction equations. Seismic hazard values have been estimated within a grid of 0.1° × 0.1 ° spacing for all of Cairo's districts at different spectral periods and four return periods (224, 615, 1230, and 4745 years). Moreover, the uniform hazard spectra have been calculated at the same return periods. The pattern of the contour maps show that the highest values of the peak ground acceleration is concentrated in the eastern zone's districts (e.g., El Nozha) and the lowest values at the northern and western zone's districts (e.g., El Sharabiya and El Khalifa).

    Islamic Cairo is one of the important Islamic monumental complexes in Egypt, near the center of present-day metropolitan Cairo. The age of these buildings is up to one thousand years. Unfortunately, many of the buildings are suffering from huge mishandling that may lead to mass damage. Many buildings and masjids were partially and totally collapsed because of 12th October 1992 Cairo earthquake that took place at some 25 km from the study area with a magnitude Mw = 5.8. Henceforth, potential damage assessments there are compulsory. The deterministic and probabilistic techniques were used to predict the expected future large earthquakes' strong-motion characteristics in the study area. The current study started with compiling the available studies concerned with the distribution of the seismogenic sources and earthquake catalogs. The deterministic method is used to provide a description of the largest earthquake effect on the area of interest, while the probabilistic method, on the other hand, is used to define the uniform hazard curves at three time periods 475, 950, 2475 years. Both deterministic and probabilistic results were obtained for bedrock conditions and the resulted hazard levels were deaggregated to identify the contribution of each seismic source to the total hazard. Moreover, the results obtained show that the expected seismic activities combined with the present situation of the buildings pose high alert to rescue both the cultural heritage and expected human losses.

  14. The prospective nuclear desalination market in Egypt

    International Nuclear Information System (INIS)

    In view of the unavoidable decline in the per capita share of the more or less constant natural fresh water resources in Egypt, water desalination is expected to play an increasing role in mitigating a future deficit in potable water supply, particularly in remote desert areas. In the present study, an attempt was made to quantify the evolution of potable water supply, demand and deficit, as well as the portion to be covered by sea water desalination. The future potable water supply was determined as the difference between the projected total renewable fresh water supply and the projected combined demand of the other consuming sectors. To project the future demand of potable water, the history of past consumption was studied and correlated with the population and gross domestic product. Three scenarios were contemplated for economic development, reflecting low, medium and high economic growth rates. The difference between potable water supply and demand is the deficit that has to be compensated for. Part of the future deficit may be covered through various means other than sea water desalination. Therefore, it was assumed that sea water desalination will cover only 10% of the deficit in potable water supply. It is concluded that there will be a demand for an additional desalination capacity of a sufficiently large magnitude around the year 2012 and beyond that will support the installation of desalination facilities larger than 100,000 m3/d. Desalination plants in this range coupled to nuclear power plants could be competitive with fossil fired plants. (author)

  15. The national waste management system in Egypt

    International Nuclear Information System (INIS)

    The waste management system in Egypt comprises operational and regulatory capabilities. Both of these activities are performed under a legislative umbrella. The legal framework is well defined by both the Decree No. 288 (1957) which allowed the establishment of the Egyptian Atomic Energy Commission (now it is the Atomic Energy Authority (AEA)) and the Law 59 (1960) which assigned the full responsibilities for licensing, management and control of the use of radioactive materials and the waste arisings to the AEA. The operational capabilities are allocated to the Hot Laboratories and Waste Management Centre (HLWMC). These capabilities include, beside the operators, the facilities for treating and conditioning liquid and solid radioactive waste. The liquid radioactive waste facility has been completed under the IAEA Technical Assistance Project. The facility can treat 10 m3/day of low level liquid radioactive waste and 2 m3/ day of medium level liquid waste. The facility was commissioned in December 1993. It uses three methods for treating liquid radioactive waste: precipitation, evaporation and ion exchange. Sludges and concentrates resulting from the treatment are conditioned by cementation in the cementation plant which is a part of the facility. The solid radioactive waste treatment includes compaction and incineration. The compacted waste will be conditioned by cementation in the cementation plant. 10 refs, 4 figs

    Cryptosporidiosis, a parasitic zoonosis, while typically a short-term infection, has a global distribution and can cause severe illness in children and other vulnerable populations. In order to inform local and regional public health personnel and providers, the authors conducted a comprehensive review of Cryptosporidium parvum (Cp) epidemiology in Egypt to establish what is known, identify critical knowledge gaps, and develop a basis for future directions in mitigating the burden associated with this illness among Egyptians and similar countries. A total of 61 published studies between 1985 & 2006 were reviewed. Nineteen studies examined immunocompetent individuals with diarrhea presenting to inpatient or outpatient clinics with a Cp prevalence ranging from 0% - 47% (median 9%, IQR 3-15%). Identified risk factors, at risk populations, ecology, environmental findings, as well as a quality assessment of the published literature are discussed. The building blocks are in place to design studies aimed at defining the disease, societal burden and evaluating public health interventions aimed at disrupting water and zoonotic transmission modalities using the most current molecular techniques. Cp diarrhea is but one of the many causes of diarrhea among Egyptians, but efforts to control this disease should also serve well to mitigate a number of infectious causes of diarrhea and given the track record of previous work hopping to see advances in the near future.

  17. Radiological Studies in the Hot Spring Region of Oyoun Mossa and Hammam Faraun Thermal Spring Areas in Western Sinai

    International Nuclear Information System (INIS)

    Radioactivity in and around the two hot springs, Oyoun Mossa and Hammam Faraun, Western Sinai has been determined. The ground water, sediment and sand samples were measured by gamma-ray spectrometer for 232Th, 226Ra and 40K isotopes. The enrichment of 226Ra in Hammam Faraun hot spring was the most prominent feature. The concentration of 226Ra in Oyoun Mossa and Hammam Faraun hot springs are 68 and 2377 Bq/kg for sediments, 3.5 and 54.7 Bq/kg for wild plants, and 205 and 1945 mBq/l for the ground water, respectively. In addition, the concentration of sand samples are 14 times larger in the area of Hammam Faraun compared with that of Oyoun Mossa. On the other hand, the concentration of 232Th in different samples are comparable in the two areas while 137Cs concentrations are relatively higher in Oyoun Mossa. For the purpose of comparison, sand samples were collected from two locations 5-12 km away from each spring. The activity concentrations of the four locations are comparable and in agreement with those from the area of the two springs except in one case. The major difference was the activity concentration of 226Ra in the area of Hammam Faraun, which is much higher. The concentrations of all detected isotopes in water samples from these two springs are much higher than that detected in 27 natural wells in north Sinai. The results of the present study indicate that water only in Hammam Faraun hot spring is contaminated with 238U-isotopes and the surrounding area is affected by this contamination. The calculated annual effective dose equivalents in the surroundings of Hammam Faraun (81.8 μSv) is superior to the maximum contaminant levels recommended.

    2012-01-01

    Full Text Available Problem statement: Sinai is increasingly suffering from an overwhelming water crisis. Runoff Water Harvesting (RWH could be a solution for this problem. The determined promising drainage basins for RWH could be used by the decision makers to propose appropriate controlling systems to overcome the problem of water scarcity and for implementing runoff farming and rain-fed agriculture. Approach: Remote sensing, geographic information systems, watershed modeling system were integrated to extract a multi-criteria-decision support system of nine thematic layers, namely; volume of annual flood, lineaments frequency density, drainage frequency density, maximum flow distance, basin area, basin slope, basin length, average overland flow distance and soil infiltration. These criteria were used for conducting a Weighted Spatial Probability Modeling (WSPM to determine the potential areas for the RWH. The potential runoff available for harvesting was estimated by applying Finkel-SCS rainfall-runoff methods. Results: The WSPM classified Sinai into four classes that graded from high (3,201-6,695 km2, moderate (35,923-35,896 km2, low (13,185-16,652 km2, very low (1.38-5.57 km2 for RWH. Promising watersheds like those of Abu Taryfya, Hamma El Hassana, Gerafi, Watir, Geraia, Heridien, Sidri, Feiran and Alaawag, are categorized as high-moderate RWH potential basins. Conclusion: These basins could be investigated in detail with larger scale to determine the appropriate locations for implementing the RWH structures and techniques. Implementing systems and techniques of RWH in the potential watersheds could open new opportunities for sustainable development in the area.

  19. Marketing and economic analysis of mango irradiation processing in egypt

    International Nuclear Information System (INIS)

    The aim of this work is to examine the marketing and economic feasibility of a project for mango irradiation in Egypt. The Egyptian market was analyzed considering the production size and cultivated area distributed over several years,the percentage of the total loss of mango that can be avoided by irradiation, the market tests in Egypt and other countries was presented and the normal distribution channels of mango when using radiation technology. The financial and economic analysis of the establishment of pallet carrier unite for the irradiation of mango was also carried out. The following investment criteria were utilized for the commercial evaluation: benefit-cost ratio, pay back period, average rate of return and net present value. The results of this analysis showed that the installation of a unit for the irradiation of mango in Egypt would be economically viable. The unit cost of irradiation would decline if the irradiator is be used as a multipurpose facility

  1. No rheumatoid arthritis in ancient Egypt: a reappraisal.

    Science.gov (United States)

    Kwiecinski, Jakub; Rothschild, Bruce M

    2016-06-01

    Antiquity of rheumatoid arthritis (RA) remains controversial, and its origins in Americas or in the Old World are disputed. Proponents of the latter frequently refer to RA in ancient Egypt, but validity of those claims has never been examined. Review of all reported RA cases from ancient Egypt revealed that none of them represent real RA, instead being either examples of changing naming conventions or of imprecise diagnostic criteria. Most cases represented osteoarthritis or spondyloarthropathies. Also review of preserved ancient Egyptian medical writings revealed many descriptions of musculoskeletal disorders, but none of them resembled RA. This suggests that RA was absent in ancient Egypt and supports the hypothesis of the New World origin of RA and its subsequent global spread in the last several centuries. PMID:26650735

  2. Clean energy investment in developing countries : wind power in Egypt

    International Nuclear Information System (INIS)

    Wind power generates only 0.7 per cent of Egypt's electricity supply despite the fact that Egypt has some of the best wind resources in the world. Demand for electricity in the country is increasing, and air quality considerations are becoming a significant concern in urban areas. This study discussed wind power developments in Egypt within the context of the country's current electricity and energy sectors. Factors supporting and constraining investment were examined, and the conditions for ensuring the large-scale implementation of wind power were explored. The study showed that the principal barrier to the widespread implementation of wind power is the low prices currently paid for wind generation by the country's tariff system. Long-term strategies are needed to build wind capacity over time and identify appropriate infrastructure investments for grid reliability. 31 refs., 12 tabs., 7 figs.

  4. Biomphalaria alexandrina in Egypt: Past, present and future

    2013-09-01

    The African species of Biomphalaria appeared as a result of the relatively recent west-to-east trans-Atlantic dispersal of the Biomphalaria glabrata-like taxon. In Egypt, Biomphalaria alexandrina is the intermediate host for Schistosoma mansoni. Biomphalaria alexandrina originated in the area between Alexandria and Rosetta and has historically been confined to the Nile Delta. Schistosoma mansoni reached Egypt via infected slaves and baboons from the Land of Punt through migrations that occurred as early as the Vth Dynasty. The suggestion of the presence of Schistosoma mansoni infection in Lower Egypt during Pharaonic times is discussed despite the fact that that there is no evidence of such infection in Egyptian mummies. It is only recently that Biomphalaria alexandrina colonized the Egyptian Nile from the Delta to Lake Nasser. This change was likely due to the construction of huge water projects, the development of new water resources essential for land reclamation projects and the movement of refugees from the Suez Canal zone to the Delta and vice versa. The situation with respect to Biomphalaria in Egypt has become complicated in recent years by the detection of Biomphalaria glabrata and a hybrid between both species; however, follow-up studies have demonstrated the disappearance of such species within Egypt. The National Schistosoma Control Program has made great strides with respect to the eradication of schistosoma; however, there has unfortunately been a reemergence of Schistosoma mansoni resistant to praziquantel. There are numerous factors that may influence the prevalence of snails in Egypt, including the construction of water projects, the increase in reclaimed areas, global climate change and pollution. Thus, continued field studies in addition to the cooperation of several scientists are needed to obtain an accurate representation of the status of this species. In addition, the determination of the genome sequence for Biomphalaria alexandrina and the

    The 2011 Arab Spring swept across the Middle East creating profound instability in Egypt, a country already challenged with poverty and internal pressures. To respond to this crisis, Catholic Relief Services led a community-based program called "Egypt Works" that included community improvement projects and psychosocial support. Following implementation, program outcomes were analyzed using the middle-range theory of adaptation to situational life events, based on the Roy adaptation model. The comprehensive, community-based approach facilitated adaptation, serving as a model for applying theory in post-crisis environments. PMID:26396214

    Cretaceous, the Burdigalian, the Tortonian and Early Quaternary. Recent tectonic activity is mainly concentrated along the Maghrebian Alpine Belt, the offshore Nile Delta, the Red Sea-East African Rifts Province, the Aqaba-Dead Sea-Bekaa sinistral strike-slip fault zone, and some major intra-plate fault zones including the Guinean-Nubian, Aswa, and central Sinai lineaments. Large, long-lived magmatic provinces developed in the Egypt-Sudan confines (Nubia), in the Hoggar-Air massifs, along the Cameroon Line and Nigerian Jos Plateau, and along the Levant margin, resulting in uplifts that influenced the paleogeography. Extensive tholeiitic basaltic magmatism at ˜200 Ma preceded continental break-up in the Central Atlantic domain, while extensive alkaline to transitional basaltic magmatism accompanied the Oligocene to Recent rifting along the Red Sea-Gulf of Aden-East African rift province.

    Full Text Available AIM/BACKGROUND: Physician’s job satisfaction is a cornerstone for improving the quality of health care, and its continuity. To identify the extent of job satisfaction and explain its main components among physicians, together with finding out the main indicators for job satisfaction. METHODS: We randomly selected physicians from the Egyptian Ministry of Health and Population Hospitals. All participants were asked to fill a self administrated questionnaire which included data pertaining socio-demographic characteristics and job satisfaction regarding salaries/incentives, monitoring, administration system, management, career satisfaction, relationship with colleagues, social support, opportunities for promotion, and job responsibilities. Satisfied was defined as satisfaction of>60%. RESULTS: Two hundred and thirty eight physicians participated in this study; with mean age of 37.1+ 9.4 years, and 70.2% were males. Only 42.9% of the physicians’ reported job satisfaction. Relationship with colleagues was the most important component of satisfaction with mean of 81.3+19.6 while, salaries/incentives were the least one with mean of 16.2+ 14. The overall current satisfying domains were not significantly associated with marital status or educational level, however it was significantly associated with specialty. Neither age nor gender was significantly associated with the degree of job satisfaction. CONCLUSION: Our results call for paying more attention to improve physicians’ job satisfaction in Egypt, to meet needed higher standards in health care. [TAF Prev Med Bull 2008; 7(2.000: 91-96

  13. [Light and blindness in ancient Egypt].

    In Ancient Egypt, light and fire, which were closely related to the Sun God Ra, were the sources of life and well-being, while the dark meant danger and death. Similar to death, darkness drops on human beings in deep sleep and they enter a space inhabited by shadows. Dreams were believed to reveal an unknown world, to give the sleeper a glimpse into the future. Vision attracts distant objects and their light, on the other hand, can hurt the eyes like a burning flame. Eyes were the most important organ in Egyptian thought, as they allowed perception of the real world. Their importance has been immortalised in the myth of the Eye of Horus that explains the role of either eye. One represents the moonlight, which disperses the darkness of the night, and the other represents the sunshine, which creates life, and both could also represents the power of human intellect. Blindness, in turn, congenital or disease-related, was considered a divine punishment. A man, thus handicapped, would sink in a state of uncertainty and darkness. To protect the eyes from blindness, people used drops and ointments, which were believed to chase away all kinds of insects and demons that threatened with a variety of eye infections. Egyptian eye doctors or physicians, carried a special kit that contained green chrysocolla and a black kohl makeup, highly appreciated as prophylaxis because they personified Osiris' humours or body fluids. These products were offered to Gods to restore the brightness of divine glance and incite sun and moon to spread their beneficial light. PMID:21192112

  14. Morphologic characteristics and migration rate assessment of barchan dunes in the Southeastern Western Desert of Egypt

    This work explores the morphologic characteristics of aeolian dune sand in the southeastern part of Western Desert of Egypt. It aims to assess the movement of barchan dunes and evaluate their environmental influence on the Toshka Project. Morphometric investigation of barchan dunes in the Toshka area revealed that most barchans have high length/width (a/c) ratios (fat to pudgy), while one-fifth of the studied barchans have lower a/c ratios and so appear normal in their morphologic forms. Statistical analysis of the main parameters of barchan dunes in Toshka and other desert regions in the Kharga (Egypt), Kuwait, Southern Morocco, California and Southern Peru demonstrates that barchans of the Toshka area are distinctive in their appearance. They are characterized by distinct aspect with higher values of length and width and greater growth in height. The high-energy wind environment in addition to the large amount of drifting sand are principal factors responsible for the unique shape of Toshka barchans. The migration rate of barchan dunes in four chosen test locations, within the central and western Toshka area, ranges from about 3 to 10.82 m/year. The calculated average migration rate of these dunes is about 6 m/year in a SSW direction. Sand encroachment is more extensive in the central and western parts of the investigated Toshka area. Risk evaluation of sand dune movements in the southeastern part of the Western Desert points to medium to high sand encroachment risk values. These may represent serious hazards to the newly-established Toshka Project, threatening roads, as well as cultivated lands in the area.

  11. The northern lakes of Egypt: Encounters with a wetland environment

    International Nuclear Information System (INIS)

    Five lakes fringe the northern coast of Egypt. Together they represent 25% of the remaining wetland habitat in the Mediterranean basin. Residents of these lakes traditionally exploited a wide variety of resources. Today these lakes face a number of threats to their existence, including large-scale reclamation and water pollution. Agricultural authorities, engineers, fishery managers, and conservationists in Egypt and abroad debate about how best to manage and develop the lake region's resources, but few of these groups understand or communicate with one another, or with residents of lake communities. This study explores how these various groups encounter the coastal lakes of Egypt, focusing particularly on Lakes Manzala and Burullus. Its purpose is to explore the ways in which the lakes, their resources and their inhabitants have been evaluated, and to analyze how underlying preconceptions, goals and structures of professional discourse influence such evaluations. The thesis is that environmental management is in reality not a rational plan but a process. Egypt is currently attempting to develop a coherent strategy to remedy its environmental problems without adversely affecting economic growth

Materials and Methods: Serum samples were collected from clinically healthy as well as suspected sheep and goats. Samples were collected during the vector breeding season from September to November 2010, from 14 Egyptian governorates which represent different geographical regions of Egypt, and were tested by Agar Gel Immuno-precipitation Test (AGPT. Results: Out of total 1293 animal serum samples (sheep-1028 and goats-265, 17.5% of sheep and 14.7% of goats serum samples were found positive. The overall prevalence of anti-BT antibodies in different governorates was 16.9%. The highest prevalence of bluetongue group specific antibodies was detected in Beni-Suef, Giza, and Al Sharqia governorates (13.2%. The results indicate that there is a necessity to run further studies to identify the negative governorates. In addition, there is a lack in information regarding the BTV serotypes in Egypt. Conclusion: This study reflected high seroprevalence of bluetongue infection in sheep than goats. The results indicated that further studies are needed to identify the vectors from different agro-climatic zones, in addition, the BTV serotypes that are circulating in Egypt.

    CERN Document Server

    2009-01-01

    For Dynamical Systems, a strong bound on multiple correlations implies the Central Limit Theorem (CLT) [ChMa]. In Chernov's paper [Ch2], such a bound is derived for dynamically Holder continuous observables of dispersing Billiards. Here we weaken the regularity assumption and subsequently show that the bound on multiple correlations follows directly from the bound on pair correlations. Thus, a strong bound on pair correlations alone implies the CLT, for a wider class of observables. The result is extended to Anosov diffeomorphisms in any dimension.

Recent advances in seismic techniques are helping in locating deeper structures, which might prove instrumental in the upgrading of the oil possibilites of the region. At present, the exploration activities are going on in the different oil and gas provinces in Egypt. These activilles are expected to increase and are also expected to expand to new areas in the eastern part of the Gulf of Suez Basin, offshore and onland, in Northern Sinai and in the Offshore Mediterranean. These new areas are believed to house very good prospects which will be tested not before long. It is also hoped that progress in seismic tools and techniques will add to the possibilities of finding more oil and gas. On connaît des accumulations d'huiles depuis 1868, quelque 10 ans après le célèbre puits de Drake en Pennsylvanie (août 1859. Ces accumulations ont été trouvées comme des suintements dans des tunnels forés pour l'extraction du soufre dans la région de Gemsa sur la côte ouest du golfe de Suez. Depuis cette époque, les activités d'exploration se sont poursuivies à travers une longue histoire d'opérations qui témoignaient des derniers développement dans les outils et les techniques. Jusqu'à maintenant, la principale province à huile d'Egypte est le bassin du golfe de Suez où la majorité des réserves ont été trouvées. D'autres provinces à hydrocarbures sont le bassin du delta du Nil, celui d'Abu Garadig et la ride d'El Alamein, les deux derniers situés dans le désert occidental. Il y a eu trois importantes découvertes de gaz dans le delta du Nil, dont deux en mer, en plus de quelques indices de gaz encore non commerciaux. Outre les découvertes mentionnées, les activités d'exploration au cours de cette longue période ont apporté une masse d'informations géologiques et géophysiques qui ont contribué largement à la connaissance géologique de l'Egypte, et en particulier à la géologie p

  2. Integrated Management Program for Radioactive Sealed Sources in Egypt IMPRSS

    International Nuclear Information System (INIS)

    Sealed sources are usually in capsules made of stainless steel. They are the size of a pen or a finger and contain one of hundreds of radioactive elements (e.g., Iridium, Radium) or their isotopes. They are air-tight and very durable, contain the radioactive material but not radiation. They are used in the health sector, industry, military, and universities. Incidents occurred in Met Halfa, Egypt, 2000 (Iridium-192); Goiania, Brazil, 1987 (Cesium-137); Mexico and Southwest U.S., 1977 -1984 (Cobalt-60); Peru, 1999 (Iridium-1992); Poland 2001 (Cobalt-60). The IMPRSS Mission is based on a joined partnership between the Egyptian Atomic Energy Authority, the Egyptian Ministry of Health, the Sandia National Laboratories, the International Atomic Energy Agency and others. The IMPRSS Mission protects human health and the environment in Egypt from mismanaged sealed sources, is developed jointly with MOH and EAEA, provides capabilities for managing radioactive sealed sources in Egypt, increases public awareness, provides education and training, improves emergency response capabilities, develops a permanent disposal facility, ensures the program is self-sustaining and ensures close coordination with the IAEA. Infrastructure how to manage sealed sources is discussed. It includes awareness, tracking and inventory control, security, recovery, conditioning and storage, recycling and disposal. Emergency response, regulatory reform, education and training and its targets are provided. The government of Egypt can protect the people of Egypt and is ready for emergencies. Prevention is the first line of defence and detection is the second line of defence. Adequate Emergency Response saves lives and adequate control reduces risk of mismanaged uses or deliberate misuses of sources. A Cradle-to-Grave approach is built on existing capabilities at EAEA and MOH

  5. Abrasive supply for ancient Egypt revealed

    International Nuclear Information System (INIS)

    In the framework of the major research scheme 'Synchronization of Civilizations in the Eastern Mediterranean Region in the 2nd Millennium B.C' instrumental neutron activation analysis (INAA) was used to determine 30 elements in pumice from archaeological excavations to reveal their specific volcanic origin. In ancient time, the widespread pumiceous products of several eruptions in the Aegean region have been used as abrasive tools and were therefore popular trade objects. The correlation of such archaeological findings to a specific eruption of known age would therefore allow to certify a maximum age of the respective stratum ('dating by first appearance'). Pumices from the Aegean region can easily be distinguished by their trace element distribution patterns. This has been shown by previous studies of the group. The elements Al, Ba, Ca, Ce, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mn, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, Ti, U, V, Yb, Zr and Zn were determined in 16 samples of pumice lumps from excavations in Tell-el-Dab'a and Tell-el-Herr (Egypt). Two irradiation cycles and five measurement runs were applied. To show the accuracy of the results obtained, typical samples of the most important pumice sources in the Aegean region, particularly from Milos, Nisyros, Kos and Thera were analyzed together with the Egyptian samples of unknown origin. A reliable identification of the samples is achieved by comparing these results to the database compiled in previous studies. The geographical positions of these islands are shown. Within the error range, most of the elements determined in typical representatives of Milos, Nisyros, Kos and Santorini were in perfect agreement with values from the literature. On the basis of the Cluster graphics presented, it is possible to relate unknown pumice to its primary source, just by comparing the relation of a few elements, like Ta-Eu and Th-Hf. One concludes that all samples except one can be related to the Minoan eruption of Thera

OBJETIVO: Estudar a prevalência de sintomas/sinais de refluxo em pacientes roncadores com suspeita de SAOS. MÉTODO: Estudo clínico corte transversal de 74 adultos Berlim positivo acompanhados em ambulatório de distúrbios do sono de centro universitário. As variáveis estudadas foram IMC, Epworth, índice de sintomas de refluxo (RSI e escala de achados endolaríngeos de refluxo (RFS, bem como seus subdomínios que podem traduzir maior inflamação. Correlações entre questionários de sono e escalas de refluxo, bem como seus subdomínios, foram feitas com significância estabelecida em p < 0,05. RESULTADOS: Noventa e oito porcento dos pacientes apresentaram sintomas e sinais sugestivos de RLF, sendo esta prevalência significativamente maior nos obesos (p = 0,002. CONCLUSÃO: A diferença significativa nos sinais inflamatórios sugestivos de RLF entre obesos e não obesos com suspeita de SAOS sugere que a obesidade pode interferir nos achados inflamatórios na faringe e laringe. A altíssima prevalência destes sintomas e sinais de refluxo nos pacientes com suspeita de SAOS demonstra a importância de aprofundar estudos nesta área.

  9. A Strong Pair Correlation Bound Implies the CLT for Sinai Billiards

    Stenlund, Mikko

    2010-07-01

    We investigate the possibility of proving the Central Limit Theorem (CLT) for Dynamical Systems using only information on pair correlations. A strong bound on multiple correlations is known to imply the CLT (Chernov and Markarian in Chaotic Billiards, 2006). In Chernov's paper (J. Stat. Phys. 122(6), 2006), such a bound is derived for dynamically Hölder continuous observables of dispersing Billiards. Here we weaken the regularity assumption and subsequently show that the bound on multiple correlations follows directly from the bound on pair correlations. Thus, a strong bound on pair correlations alone implies the CLT, for a wider class of observables. The result is extended to Anosov diffeomorphisms in any dimension. Some non-invertible maps are also considered.

Noteworthy, the scarcity of the freshwater resources and close proximity to the active seismic zones of the Gulf of Aqaba implicate geophysical investigations for the fresh groundwater aquifers and construct a design response spectrum, respectively. Accordingly, 14 VESs, hydro/engineering geophysical analysis, pumping tests, downhole seismic test, a design response spectrum for buildings, and borehole data were carried out in the study area. The unconfined freshwater aquifer was effectively depicted with true resistivities, thickness, and EC ranged from 56 to 135 Ω m, 11 to 112 m, and 1.4 to 7.1 mS/m, respectively. The Northeastern part was characterized by higher aquifer potentiality, where coarser grains size, highest thickness (112 m), high true resistivity (135 Ω m), groundwater flow (0.074 m3/day), tortuosity (1.293-1.312), formation resistivity factor (4.1-4.6), and storativity (0.281-0.276). An increase in pumping rate was accompanied by an increase in well loss, increase in aquifer losses, decrease in well specific capacity, and decrease in well efficiency. Design response spectrum prognosticated the short buildings (<7 floors) in RMNP to be suffering from a high peak horizontal acceleration and shear forces for acceleration between 0.25 and 0.35 g. Therefore, appropriate detailing of shear reinforcement is indispensable to reduce the risk of structural damages at RMNP.

  14. Mount Sinai leverages smartphone technology, aiming to boost care, coordination of ED patients while also trimming costs.

    Science.gov (United States)

    2015-05-01

    Mount Sinai Hospital in New York, NY, is using smartphone technology to enhance follow-up calls to senior patients who have visited the ED, and to help provide acute-level care to select patients in their own homes. Investigators are hoping to show that these approaches can improve care and coordination while trimming costs, and they expect that patients will approve of these new approaches as well. While senior patients are still in the ED, nurse coordinators will work with them to load a HIPAA-compliant application to their smartphones so they can conduct face-to-face follow-up calls that meet HIPAA standards. Nurses say the face-to-face communications enhance their ability to assess how patients are doing following their ED visit. The hospital is also testing a program that enables some ED patients who meet inpatient criteria to receive this care in the home setting through the use of a mobile acute care team (MACT). In the case of emergencies, the MACT team relies on community paramedics who will visit the patients' homes and provide care under the direction of MACT physicians who are linked in to these visits via smartphone technology.

    2011-10-01

    Full Text Available Abstract Background As low- and middle-income countries experience economic development, ensuring quality of health care delivery is a central component of health reform. Nevertheless, health reforms in low- and middle-income countries have focused more on access to services rather than the quality of these services, and reporting on quality has been limited. In the present study, we sought to examine the prevalence and regional variation in key management practices in Egyptian health facilities within three domains: supervision of the facility from the Ministry of Health and Population (MOHP, managerial processes, and patient and community involvement in care. Methods We conducted a cross-sectional analysis of data from 559 facilities surveyed with the Egyptian Service Provision Assessment (ESPA survey in 2004, the most recent such survey in Egypt. We registered on the Measure Demographic and Health Survey (DHS website http://legacy.measuredhs.com/login.cfm to gain access to the survey data. From the ESPA sampled 559 MOHP facilities, we excluded a total of 79 facilities because they did not offer facility-based 24-hour care or have at least one physician working in the facility, resulting in a final sample of 480 facilities. The final sample included 76 general service hospitals, 307 rural health units, and 97 maternal and child health and urban health units (MCH/urban units. We used standard frequency analyses to describe facility characteristics and tested the statistical significance of regional differences using chi-square statistics. Results Nearly all facilities reported having external supervision within the 6 months preceding the interview. In contrast, key facility-level managerial processes, such as having routine and documented management meetings and applying quality assurance approaches, were uncommon. Involvement of communities and patients was also reported in a minority of facilities. Hospitals and health units located in Urban

    The present drinking water purification system in Egypt Uses surface water as a raw water supply without a pre-liminary filtration process.On the other hand,chlorine gas iS added as a disinfectant agent in two steps,pre- and post.chlorination.Due to these reasons most of water treatment plants suffer low fltering effectiveness and produce the trihalomethane (THM) species as a chlorination by-product.The Ismailia Canal represents the most distal downstream of the main Nile Rivet.ThUS its water contains all the proceeded pollutants discharged into the Nile.In addition.the downstream reaches of the canal act as an agricultural drain during the closing period of the High Dam gates in January and February every year.Moreover,the wide in-dustrial zone along the upstream course of the carlal enriches the canal water with high concentrations of heavy metals.The obtained results indicate that the canal gains up to 24.06×106m3 of water from the surrounding shallow aquifer during the closing period ofthe High Dam gates,while during the rest ofthe year,the callal acts as an influent stream losing about 99.6×106m3 of its water budget.The reduction oftotaI organic carbon(TOC) and suspended particulate mattes(SPMs)should be one of the central goals of any treatment plan to avoid the disinfectants by-products.The combination of sedimentation basins.gravel pre-filtration and slow sand filtration,and underground passage with microbiological oxidation-reduction and adsorption criteria showed good removal of parasites and bacteria and complete elimination of TOC.SPM and heavy metals.Moreover,it reduces the use of disinfectants chemicals and lowers the treatment costs.However,this purification system under the arid climate prevailing in Egypt should be tested and modified prior to application.

    2006-01-01

    Full Text Available The karyotype and C-banding pattern of the unstriped grass rat Arvicanthis niloticus from four localities in Egypt are presented. All individuals karyotyped, as a rule, have the same diploid number of 2n = 62 and autosomal Fundamental Number of aFN = 62. In addition, all chromosomes have a large centromeric block of fairly uniform size. However, an additional interstitial or telomeric small C-band is scored in some chromosomes. Nevertheless, frequent heteromorphism in the morphology and heterochromatin content of both the homologous chromosomes of the pair No. 1 and the X chromosome are scored in some individuals from the four localities and led to an aFN = 63. Accordingly, four forms or cytotypes, namely ANI-1a, ANI-1b, ANI-1c and ANI-1d, are recognized based on this variation, which is mostly attributed either to addition or deletion of a heterochromatic segment as a result of pericentric inversions. Of these four forms, the ANI-1a is considered ancestral for A. niloticus in Egypt and is closely similar to that of the Ethiopian A. dembeensis, regardless the contradiction concerned with nomenclature of the X chromosome, while the karyotypes of the other forms are synapomorphy of the form ANI-1a and showed as well a relative resemblance to those of the Ethiopian A. abyssinicus and A. blicki. Therefore, it is concluded that the genus Arvicanthis would be represented by an Egyptian-Ethiopian radiation (A. niloticus, A. dembeensis, A. abyssinicus and A. blicki and by a Central-Western African one, including the karyotypes described as A. centralis and A. solatus. Moreover, A. niloticus should be regarded no longer as a single species but as a cluster of several proper species.

    2016-04-01

    The study investigates the entropy of Egypt's virtual water trade gravity distribution, in order to provide a chart of Egypt's embodied water balance in agricultural trade, in relation to distances with its major counterparties. Moreover, our calculations on the amount of the embodied water traded between Egypt and each of its partners take place according to a combination of available data on the blue, green and grey water footprints as well as the Food and Agriculture Organization (FAO) database of traded amounts per crop type. A study on the virtual water trade gravity, enables us to enrich former related studies (Fracasso 2014; Fracasso, Sartori and Schiavo 2014) via examining Egypt's water supply dependence on the Nile River and if comparative advantages -purely from the side of water quantities- can be identified via recognizing which water footprint categories are particularly high. Additionally, this methodology can comprise -from a fundamental level- a guide for revealing the importance of water footprint types for Egypt's agricultural sector; hence, Egypt's potential comparative advantages, as far as quantitative water endowments are exclusively concerned (without consideration of water or crop prices). Although it is pointed out very correctly by various authors (Antonelli and Sartori 2014) that the virtual water trade concept does not incorporate many important aspects of water supply -such as heavy water price subsidizing- to be used accurately for the identification of comparative advantages, we consider that the purely quantitative examination can provide strong fundamental indications -especially for green and grey water footprints, which are hypothesized to be less sensitive to subsidizing. In overall, this effect can very well provide a primary indication on the organization of the global alimentation trade network (Yang et al. 2006). The gravity equation used contains water footprint data for the 15 top traded crops and the distances for Egypt

    Pandemic influenza has great potential to cause large and rapid increases in deaths and serious illness. The objective of this paper is to develop an agent-based model to simulate the spread of pandemic influenza (novel H1N1) in Egypt. The proposed multi-agent model is based on the modeling of individuals' interactions in a space time context. The proposed model involves different types of parameters such as: social agent attributes, distribution of Egypt population, and patterns of agents' interactions. Analysis of modeling results leads to understanding the characteristics of the modeled pandemic, transmission patterns, and the conditions under which an outbreak might occur. In addition, the proposed model is used to measure the effectiveness of different control strategies to intervene the pandemic spread.

    Archaeologists working in Egypt have rarely considered the local/global ramifications and responsibilities of their field practices: many continue to operate under what might be termed the residual effects of colonialism. Taking an explicitly postcolonial stance I argue that there is much more at stake than the intellectual enterprise. This paper outlines the ways in which scholars could undertake a more engaged archaeology and how we might more closely be involved with the people and pasts of modern Egypt. The connected tensions of tourism and terrorism are foregrounded, demonstrating that heritage issues are salient to both spheres. Finally, I explore the nation's relationship to its pharaonic past over the past few centuries and include some contemporary articulations and representations. PMID:11193011

    Full Text Available Mobile banking (m-banking faces various types of resistance that may hinder customers’ adoption inEgypt. This study identifies three groups of m-banking non-adopters, namely postponers, opponents andrejectors. The objective of the study is to explore the reasons for resisting m-banking services in Egypt andwhether it differs with regards to these customer groups. Accordingly, a questionnaire was distributed, Chisquare tests, Kruskal-Wallis H tests and one-way analysis of variance (ANOVA test. Frequencies andcross tabulations were used. The results indicate that the three non-adopter groups differ significantly withrespect to usage, value, and image barriers. On the other hand, risk and tradition barriers did not showany statistical significance; however, risk barrier received the highest overall mean. Significant relationsbetween usage, risk and image barriers with the gender and level of education were noted. Finally, findingsenabled a clear mapping between Hofstede’s cultural dimensions and the study’s results.

    The solution obtained with 3D Euler deconvolution gives better-focused depth estimates, which are closer to the real position of sources; the results presented here can be used to constrain depth to active crustal structures (fault system, magmatic activity and subduction zones) for southeastern Mediterranean and northern Egypt. The results indicated that the area was affected by sets of structural systems, which primarily trended in the NE-SW to NNE-SSW and NW-SE, directions. The estimated shallow Bouguer results (for SI dikes, sills and flows models) shows an abrupt change depth values (1-8 km) almost clustered along the eastern segment of the Cyprian arc, Indicates continuation of the ophiolite at a depth below younger sediments of the Latakia and southern Antalya Basins. This means that, the Eratosthenes Seamount block is in the process of dynamically subsiding beneath Cyprus to the north and thrusted onto the Levantine Basin to the south. Nevertheless, the Cyprian arc region is dominated by several compressional shallow fault systems (0-4 km) trended E-W to WNW direction, which may initiated due to the northward-directed movement of Africa and ongoing subducting the Levant oceanic segment beneath the Tauric arc south of Cyprus. However, the deep magnetic depths (28 km, for SI of dipole model) correspond more closely to the Moho depth in the oceanic regions of marine part, with a high proportion of Younger Granites (Eratosthenes Seamount, Florence Rise, South Cyprus, eastern part of Levantine Basin and north Nile Cone) which are accompanied with low heat flow values. We can state that the clustering of most shallow earthquakes along this structures (especially beneath southern part of Florence Rise) may most likely be attributed to the active mantle upwelling (volcanic earthquakes), which are ultimately related to volcanic processes. Whereas, the Moho depth reaches to 35 km beneath the continental regions of Nile Delta basins and northern Sinai, which are

    Full Text Available The electrophoretic profile of cerebrospinal fluid proteins and albumin quota was studied in healthy dogs and dogs with distemper in either nervous or non-nervous phases. Cerebrospinal fluid (CSF samples from 30 dogs were collected by puncture of the cisterna magna. The total protein content, the albumin quota, and the electrophoretic fraction of CSF proteins in agarose gel plates were evaluated. Results were similar in healthy dogs and dogs with distemper and no nervous signs, but were significantly increased in the group of dogs with distemper showing nervous signs. The study of CSF protein profile proved useful and contributed significantly on the detection of central nervous system disorders and damages to the blood-brain barrier during the nervous phase of distemper.Estudaram-se o perfil eletroforético das proteínas liquóricas e a cota de albumina em cães sem e com cinomose na fase neurológica e não-neurológica. A punção da cisterna magna para a obtenção de amostras de liquor realizou-se em 30 cães. Analisaram-se teores de proteínas totais, cota de albumina e fracionamento eletroforético das proteínas liquóricas em gel de agarose. Os resultados foram semelhantes nos cães normais e nos cães com cinomose sem sinais neurológicos e significativamente elevados no grupo de cães com cinomose apresentando sinais neurológicos. O estudo do quadro protéico do líquido cérebroespinhal foi útil e contribuiu significativamente na detecção de lesões ao sistema nervoso central e de danos à barreira hematoencefálica durante a fase neurológica da cinomose.

  6. Inflation and Inflation Uncertainty Revisited: Evidence from Egypt

    Directory of Open Access Journals (Sweden)

    Mesbah Fathy Sharaf

    2015-07-01

    Full Text Available The welfare costs of inflation and inflation uncertainty are well documented in the literature and empirical evidence on the link between the two is sparse in the case of Egypt. This paper investigates the causal relationship between inflation and inflation uncertainty in Egypt using monthly time series data during the period January 1974–April 2015. To endogenously control for any potential structural breaks in the inflation time series, Zivot and Andrews (2002 and Clemente–Montanes–Reyes (1998 unit root tests are used. The inflation–inflation uncertainty relation is modeled by the standard two-step approach as well as simultaneously using various versions of the GARCH-M model to control for any potential feedback effects. The analyses explicitly control for the effect of the Economic Reform and Structural Adjustment Program (ERSAP undertaken by the Egyptian government in the early 1990s, which affected inflation rate and its associated volatility. Results show a high degree of inflation–volatility persistence in the response to inflationary shocks. Granger-causality test along with symmetric and asymmetric GARCH-M models indicate a statistically significant bi-directional positive relationship between inflation and inflation uncertainty, supporting both the Friedman–Ball and the Cukierman–Meltzer hypotheses. The findings are robust to the various estimation methods and model specifications. The findings of this paper support the view of adopting inflation-targeting policy in Egypt, after fulfilling its preconditions, to reduce the welfare cost of inflation and its related uncertainties. Monetary authorities in Egypt should enhance the credibility of monetary policy and attempt to reduce inflation uncertainty, which will help lower inflation rates.

    2010-09-15

    Egypt is a fast growing country with 78.9 million population and annual per capita installed power 0.286 MW as of July 2008. Moderate to mature population and economic growth trends forecast population and annual per capita installed power to reach 111 millions and 0.63 MW, respectively by 2032; and 128 millions at per capita power of 1.02 MW by 2052. With these trends in consideration installed electricity generation capacity are forecasted at 70 GW by 2032 and 132 GW by 2052 as compared to the 2008 installed power of 22.6 GW. Meeting these demands is almost impossible using known limited national fossil fuel reserves. Current electricity generation policy exhausts about 65% of country's total fossil production. Crude oil reserves are expected to deplete by 2012, while gas reserves will be overstrained starting from 2030. A major policy shift towards the use of non-fossil resources is to be adopted. In the article Egypt's major primary energy resources are evaluated. Electricity generation plans till 2022 are presented and an electricity generation strategy based on gradual introduction of nuclear power starting from 2018 is outlined. A balanced generation mix based on 72.7% fossil, 13% nuclear and 14.3% renewables is targeted by 2052. The mix is supposed to meet Egypt's electricity needs by 2052 and to improve country's energy sustainability. (author)

    Sludge dewatering and treatment may cost as much as the wastewater treatment. Usually large proportion of the pollutants in wastewater is organic. They are attacked by saprophytic microorganisms, i.e. organisms that feed upon dead organic matter. Activity of organisms causes decomposition of organic matter and destroys them, where the bacteria convert the organic matter or other constituents in the wastewater to new cells, water, gases and other products. Demolition activities, including renovation/remodeling works and complete or selective removal/demolishing of existing structures either by man-made processes or by natural disasters, create an extensive amount of wastes. These demolition wastes are characterized as heterogeneous mixtures of building materials that are usually contaminated with chemicals and dirt. In developing countries, it is estimated that demolition wastes comprise 20% to 30% of the total annual solid wastes. In Egypt, the daily quantity of construction and demolition (C&D) waste has been estimated as 10 000 tones. That is equivalent to one third of the total daily municipal solid wastes generated per day in Egypt. The zabbaliin have since expanded their activities and now take the waste they collect back to their garbage villages where it is sorted into recyclable components: paper, plastics, rags, glass, metal and food. The food waste is fed to pigs and the other items are sold to recycling centers. This paper summarizes the wastewater and solid wastes management in Egypt now and future. PMID:23569767

However, the high cost of these agents restricts their availability to countries where patients and/or health care systems are able to afford them. Licensing these biopharmaceuticals as biosimilars after expiration of their patents might increase access to such medicines at an affordable price in developing countries. South Egypt Drug Industries Company (SEDICO is an Egyptian pharmaceutical company that has had the opportunity to manufacture some of these drugs. SEDICO biotechnology products, such as insulin, erythropoietin, streptokinase, angiokinase, follicle-stimulating hormone, aprotinin, filgrastim, and somatropin, have been available on the Egyptian market for more than 6 years. For this paper, erythropoietin, which has been investigated over a number of years, was chosen as a representative example of SEDICO biotechnology products. Our findings confirm that SEDICO erythropoietin can compete with the originator epoetins on the Egyptian market with high quality and at a lower cost.Keywords: biosimilars, developing countries, insulin, human growth hormone, erythropoietin, epoetin, Egypt

    1995-10-01

    The first 24-hour AIDS hotline in the Arab world will open in Cairo, Egypt, in October 1995. The opening of the new service marks a change in attitude on the part of the Egyptian government, which has maintained a discreet AIDS control program in the past. Approval from religious leaders was necessary for the new program to begin; the United Nations Children's Fund (UNICEF) played a prominent role in negotiations. The "Counsel and Hot Line Centre," which will be based in Imbala district, will employ 19 people, including two doctors and two psychologists. The Centre was funded with US$300,000 from the Ford Foundation. Currently, 478 persons with HIV infections and 110 people with AIDS have been reported. The ministry estimates that there are 5000-7000 persons with HIV infections in Egypt. Although these figures were greeted with suspicion by organizations outside of Egypt, subsequent testing has indicated low prevalence rates for this country, despite high tourism and a large population of migrant workers.

    Egypt is one of the countries hardest hit by global and climate change. Challenges include population growth; increased demands for food, water, and energy; as well as changing land use patterns and urbanization. Egypt's part of the Mediterranean is characterized by a very complex hydrological system, as it lacks rainfall (Cairo average 30 mm/year) and it is completely dependent on the Nile river flow. The growth of the Egyptian population and its economy in the near future leads to an increase in the demand for water and the overall water allocation priority basically is: first drinking water, then industry, and whatever is remaining will be available for agriculture and nature. Because the agricultural sector uses more than 80 per cent of available water, the main option available to reduce water scarcity in the priority sectors of the economy is to allocate less to the agriculture sector. Scientifically based advances in facing future drought and water scarcity through innovations increasing yields and food security by measures leading to "more crop per drop" are required. New and modern large- and medium-scale agriculture is being developed in desert areas with participation of the private sector for investments. To prepare the farming community and others elsewhere, for the future situation of water shortages, a paradigm shift is needed. New farming systems under tight water supply conditions are in development to prepare for a future with less water. Egyptian farming systems need a major transition to prevent further marginalization of agriculture, which would also have a major impact on food security. Central to this transition should be the increase of value generated per volume available water, also referred to as "more crop per drop" or "more cash per splash". There is room for the urgently required improvement: the present return on water in agriculture in Egypt is about US 0.25 /m3, where values of over US 1 /m3 are "easily" reached elsewhere. Moreover

  12. NRIAG's Effort to Mitigate Earthquake Disasters in Egypt Using GPS and Seismic Data

    Science.gov (United States)

    Mahmoud, Salah

    It has been estimated that, during historical time more than 50 million people have lost their lives in earthquakes during ground shaking, such as soil amplification and/or liquefaction, landslides and tsunamis or its immediate aftereffects, as fires. The distribution of population takes generally no account of earthquake risk, at least on a large scale. An earthquake may be large but not destructive, on the other hand, an earthquake may be destructive but not large. The absence of correlation is due to the fact that, great number of other factors entering into consideration: first of all, the location of the earthquake in relation to populated areas, also soil conditions and building constructions. Soil liquefaction has been identified as the underlying phenomenon for many ground failures, settlements and lateral spreads, which are a major cause of damage to soil structures and building foundations in many events. Egypt is suffered a numerous of destructive earthquakes as well as Kalabsha earthquake (1981, Mag 5.4) near Aswan city and the High dam, Dahshour earthquake (1992, Mag 5.9) near Cairo city and Aqaba earthquake (1995, Mag 7.2). As the category of earthquake damage includes all the phenomena related to the direct and indirect damages, the Egyptian authorities do a great effort to mitigate the earthquake disasters. The seismicity especially at the zones of high activity is investigated in details in order to obtain the active source zones not only by the Egyptian National Seismic Network (ENSN) but also by the local seismic networks at, Aswan, Hurghada, Aqaba, Abu Dabbab and Dabbaa. On the other hand the soil condition, soil amplification, soil structure interaction, liquefaction and seismic hazard are carried out in particular the urbanized areas and the region near the source zones. All these parameters are integrated to obtain the Egyptian building code which is valid to construct buildings resist damages and consequently mitigate the earthquake

  14. Gamma radiation sterilization service centre in a developing country: Egypt

    International Nuclear Information System (INIS)

    Radiation has been used for the sterilization of medical products commercially for more than 50 years. During this period, the disposable medical products market has undergone enormous growth, and with it, the use of ionizing radiation as a method of sterilization. Currently, 40-50% of disposable medical products manufactured in North America are radiation sterilized. Over 200 gamma irradiators are being operated for a variety of purposes in 55 countries worldwide, and 120 of these plants are located in Europe and the USA. Syringes, surgical gloves, gowns, masks, sticking plasters, dressings, 'tetrapacks', bottle teats for premature babies, artificial joints, food packaging, raw materials for pharmaceuticals and cosmetics, and even wine corks are gamma sterilized. An increasing number of electron accelerators are also being used, although they currently process a minority of radiation sterilized products. The use of an e-beam as a radiation source has many attractive features, such as nearly instantaneous dose delivery, scalability for different throughput and the capability to integrate into a manufacturing process. However, gamma irradiators are difficult to replace, especially for non-uniform and high density products. There are a few facilities in Africa using gamma radiation for various radiation applications, including the sterilization of medical products. In Egypt this was embarked upon in the 1970s, and in 2004 the gamma radiation service centre processed more than 11 000 m3 of medical products and about 760 t of dried foodstuffs. It requires meticulous and detailed planning and a development process before such a technology can be established. In addition, a certain environment (e.g. economic, industrial and technical) is required before one can successfully embark on this. There are several countries in Africa that are almost ready to follow that path with some guidance. The experience in Egypt about this development may be useful as a guide for other

  15. Nummulite biostratigraphy of the Eocene succession in the Bahariya Depression, Egypt: Implications for timing of iron mineralization

    Afify, A. M.; Serra-Kiel, J.; Sanz-Montero, M. E.; Calvo, J. P.; Sallam, E. S.

    2016-08-01

    In the northern part of the Bahariya Depression (Western Desert, Egypt) the Eocene carbonate succession, unconformably overlying the Cretaceous deposits, consists of three main stratigraphic units; the Naqb, Qazzun and El Hamra formations. The Eocene carbonates are relevant as they locally host a large economic iron mineralization. This work revises the stratigraphic attribution of the Eocene formations on the basis of larger benthic foraminifers from both carbonate and ironstone beds. Eight Nummulites species spanning the late Ypresian - early Bartonian (SBZ12 to SBZ17) were identified, thus refining the chronostratigraphic framework of the Eocene in that region of Central Egypt. Moreover, additional sedimentological insight of the Eocene carbonate rocks is presented. The carbonate deposits mainly represent shallow marine facies characteristic of inner to mid ramp settings; though deposits interpreted as intertidal to supratidal are locally recognized. Dating of Nummulites assemblages from the youngest ironstone beds in the mines as early Bartonian provides crucial information on the timing of the hydrothermal and meteoric water processes resulting in the formation of the iron ore mineralization. The new data strongly support a post-depositional, structurally-controlled formation model for the ironstone mineralization of the Bahariya Depression.

  4. Preliminary seismic hazard assessment, shallow seismic refraction and resistivity sounding studies for future urban planning at the Gebel Umm Baraqa area, Egypt

    International Nuclear Information System (INIS)

    Gebel Umm Baraqa Fan, west Gulf of Aqaba, Sinai, is one of the most important tourism areas in Egypt. However, it is located on the active Dead Sea-Gulf of Aqaba Levant transform fault system. Geophysical studies, including fresh water aquifer delineation, shallow seismic refraction, soil characterization and preliminary seismic hazard assessment, were conducted to help in future city planning. A total of 11 vertical electrical soundings (1000–3000 m maximum AB/2) and three bore-holes were drilled in the site for the analysis of ground water, total dissolved solids (TDS) and fresh water aquifer properties. The interpretation of the one-dimensional (1D) inversion of the resistivity data delineated the fresh water aquifer and determined its hydro-geologic parameters. Eleven shallow seismic refraction profiles (125 m in length) have been collected and interpreted using the generalized reciprocal method, and the resulting depth–velocity models were verified using an advanced finite difference (FD) technique. Shallow seismic refraction effectively delineates two subsurface layers (VP ∼ 450 m s−1 and VP ∼ 1000 m s−1). A preliminary seismic hazard assessment in Umm Baraqa has produced an estimate of the probabilistic peak ground acceleration hazard in the study area. A recent and historical earthquake catalog for the time period 2200 BC to 2006 has been compiled for the area. New accurate seismic source zoning is considered because such details affect the degree of hazard in the city. The estimated amount of PGA reveals values ranging from 250 to 260 cm s−2 in the bedrock of the Umm Baraqa area during a 100 year interval (a suitable time window for buildings). Recommendations as to suitable types of buildings, considering the amount of shaking and the aquifer properties given in this study, are expected to be helpful for the Umm Baraqa area

    In Egypt, avian influenza A subtype H5N1 and H9N2 viruses are enzootic in poultry. The control plan devised by veterinary authorities in Egypt to prevent infections in poultry focused mainly on vaccination and ultimately failed. Recently, widespread H5N1 infections in poultry and a substantial increase in the number of human cases of H5N1 infection were observed. We summarize surveillance data from 2009 through 2014 and show that avian influenza viruses are established in poultry in Egypt and are continuously evolving genetically and antigenically. We also discuss the epidemiology of human infection with avian influenza in Egypt and describe how the true burden of disease is underestimated. We discuss the failures of relying on vaccinating poultry as the sole intervention tool. We conclude by highlighting the key components that need to be included in a new strategy to control avian influenza infections in poultry and humans in Egypt. PMID:26886164

    1979-04-01

    The International Energy Assessment Program between Egypt and the U.S. was formulated from mid-March to mid-July, 1978. The assessment identified energy demand and supply options for Egypt that are consistent with its indigenous energy resources; assessed Egypt's ability to effectively use those options; and identified measures by which Egypt's energy-planning activities could be improved. The assessment addressed all known and potential energy supply options (oil, gas, coal, oil shale, hydroelectric, nuclear power, geothermal, solar, wind, and biomass). Using the Reference Energy System, two future energy supply/demand balances are constructed (for 1985 and the year 2000) and these are compared with a historical (1975) supply/demand balance. The feasibility of each of the options is established in terms of the availability of the required resources and of the processing, conversion, transport, and utilization technology.

    The principal features of the existing environment of Egypt are characterized and the main problem areas identified in Annex 11. The environmental, health, and associated social issues that must be considered in choosing from among the options available to Egypt for meeting projected future energy needs are identified. The environmental impacts associated with these options are discussed and observations are made of alternte ways to minimize environmental insults. Annex 12, Manpower, analyzes the energy-related manpower situation of Egypt. Manpower education and training resources of Egypt; the existing manpower base of Egypt; manpower needs of the energy strategies; a comparison of manpower needs and existing manpower base; and the underlying economic and social factors that will make Egypt energy facility development very difficult to plan and execute are discussed. Annex 13 summarizes a preliminary analysis of the capital, labor, materials, and equipment resources required to implement alternative Egyptian energy futures and documents the assessment of several Egyptian energy development programs selected by the DOE. It egins with brief overviews of the ESPM model and data base. It then describes the method by which the system was adapted to Egyptian conditions and the results of this modification. The comparison Case energy development program is described, followed by a summary of ESPM-derived facility and resource requirements. Finally, the sensitivity of these results to several alternative energy strategies is illustrated.

Dessa forma, a condensação de água residual presente no gás pode iniciar um processo corrosivo localizado, que acarreta prejuízo à estrutura dos gasodutos. Devido à grande extensão dos dutos, os corrosivos comprometem a qualidade do gás e causam grandes transtornos de ordem operacional. Para avaliar a redução da espessura da parede metálica do duto, proveniente de efeitos corrosivos, e identificar fissuras e outras não-conformidades, é fundamental que seja feito o monitoramento contínuo e que se utilizem técnicas e métodos de manutenção preventiva. Atualmente, as técnicas adotadas para tal avaliação consistem na inclusão de um corpo de prova, conhecido como PIG (pipeline inspection gauge, com varredura por meio de ultra-som e termografia, além de levantamentos de campo especiais realizados sobre a superfície do solo. Visando a otimizar o processo de detecção, com vistas à redução de custos, o monitoramento da região interna dos dutos é realizado por um elemento autônomo provido de câmeras com infravermelho.

    The electric energy consumption rate in Egypt has an average increase of 7% per year through the last three decades. In order to satisfy the ever increasing energy demand, several actions were, and have to be taken. These actions have to be carried out in parallel. The one having the greatest effect is the measures carried out for energy conservation and loss reduction. Diversifying the energy source such as utilization of Renewable Energy technologies can contribute to satisfying the demand and extending the hydro-carbon reserves life. Regional integration of electrical networks will save expenditures used to build additional power plants.

It shows that the Egyptian government from time to time often adopts a harsh policy toward any forms of extremism in the name of Islam. However, persecution led to nothing but the increase of radical Islamism. This occurred because the Islamist movement failed to integrate their ideas in the real political domain. Failure in integration to both political and social life fueled further exclusivism. Keywords: Islamism, Egypt, Muslim Brotherhood, Modern Arab World

    Based on a study of mummies, skeletons, burial rites, medical instruments, medicaments, literature and objets d'art from Ancient Egypt before the Hellenistic Period, the understanding of the eye, its diseases and their treatment at that time is described. Magic spells, religious rites and medical treatments, especially with eye ointments, were probably used often complementary to one another. We must be very cautious about our conclusions in regard to the effectiveness of the treatments. Eye diseases have been depicted only exceptionally in Egyptian art, except for blindness and 'symbolic blindness'. PMID:9253993

    Full Text Available The perceptions of Islamic banking professionals are surveyed through a questionnaire to explore whether the process of risk management mediates board involvement in risk management on risk management practices of Islamic banks in Malaysia and Egypt. The findings of this study identified that the Islamic banks are somewhat efficient in their risk management process. Furthermore, high involvement of boards in risk management will significantly increase risk management process, and in turn, leads to significantly higher risk management practices in the organizations. Hence, boards should take formal responsibility for setting, managing and periodically assessing the risk management culture of the organizations.

  9. Characteristic aerial and ground radioactives of basement and sedimentary rocks in (Egypt): relations and natural cycles across geologic time

    International Nuclear Information System (INIS)

    Each geologic unit, exposure, formation or rock group of the exposed precambrian I (igneous and metamorphic) basement complex (Upper proterozoic) and phanerozoic cover sediments in an area covering about 4500 km2 located in the central eastern desert of egypt, has been found to possess certain radioactivity characteristics and levels. Minimum values of radiation are generally associated with the first basement volcanics, maximum values are correlated are correlated with the third basement plutonites and phosphate formation (upper cretaceous), while intermedialte values are connected with the first basement sediments and upper eocene-quaternary fifth detrital-calcareous-evaporite sediments. Therefore, the radioactivities of various rock groups of the precambrian I basement complex - except the first basement sediments sediments- correlate progressively well with their chronology. Generally, the increase of radioactivity within this complex is connected with the transition into final stages of the magmatic evolution

  11. Latest Pleistocene gusty intensified winds forced Sinai/Negev sand abrasion into finer grains: An example of active ergs as mega grinders

    Science.gov (United States)

    Enzel, Y.; Amit, R.; Crouvi, O.; Porat, N.

    2010-12-01

    Our research results from the edge of the Sinai-Negev erg indicate that ergs are mega-grinders of sand into very fine sand and silt under gusty and windy late Quaternary climates and in ancient aeolian deserts environments. In the carbonate terrain of the northern Sinai-Negev desert, only sand abrasion in an active erg could have produced the large quantities of quartzo-feldspathic silts constituting the late Quaternary northwestern Negev loess. In the continuum of source to sink, i.e. from sand of dunes (mostly medium sand with minor amounts of fine sand) to the silts in loess, the very fine sand is, yet, unaccounted for in the record. In the current research we focus on and demonstrate that as predicted by experiments, abrasion by fast advancing dunes generated large quantities of very fine sand (60-110 μm) deposited within the dune field and in close proximity downwind. This very fine sand is usually absent from the particle size distribution of either the dunes or downwind loess and must have been generated under gusty winds 13-11 ka. These intensified frequent winds generated sand/dust storms during the Younger Dryas in the southeastern Mediterranean. These very fine sands, the products of dune sand abrasion, filled small basins that were formed by the same advancing dunes under these same winds. Elsewhere, outside these sampling basins, it is difficult to identify these sands as a distinct product that point to a very windy episode.

    2015-05-01

    Full Text Available The UNESCO launched a campaign #unite4heritage in Egypt to defeat extremism and intolerance. The message of such campaigne is peace, dialogue and unity embedded in cultural heritage. As culture and tourism are linked together, such message could be delivered through improving culture heritage tourism in Egypt. Islamic landmarks  are considered as a part of human heritage. Therefore, the purpose of this study is to identify how much tour operators in Egypt include Islamic landmarks in their programs to determine the obstacles facing promoting cultural tourism in Islamic landmarks' areas. Additionally, the study would identify positive results in the case of developing heritage tourism in Egypt. To achieve a high result, a survey approach was employed to collect data from 100 tour operators, using a completed questionnaire technique as well as a Likert Scale and statistical models in order to test and interpret the research outcomes. The research findings indicated that although tour operators in Egypt are convinced of the significance of the Islamic landmarks, there is no contradiction between creating global understanding and at the same time achieving benefit to the local community. However, there is a range of obstacles facing promoting such type of tourism in Egypt. Keywords: Culture heritage tourism, community, Egypt, Islamic civilization.

  14. Use of environmental isotopes in the quantification of the water budget of the nile delta Egypt

    International Nuclear Information System (INIS)

    Expanded reuse of drainage waters for irrigation in Egypt is a central component of future agricultural planning for the country. Sources of the salinity of the drainage water discharge are often difficult to quantify with confidence. Variations of the stable environ mental isotope composition of water molecules within the irrigation network, which are quite sensitive to evaporation (but not transpiration ) and to mixing with water components other than Nile water, can provide new useful information for quantifying water budget of the Nile Delta. During the spring time of 1985, the drainage water of the Delta was enriched with deuterium and oxygen-18, only moderately above the average of the Nile. The magnitude of this enrichment for deuterium, when calibrated against heavy isotope enrichment trends for two evaporation pan experiments near Cairo at the southern apex of the Delta and Saha in the middle portion, indicates that about 6% of the original irrigation water volume was lost to evaporation through the system between Cairo and the discharge to the drainage network, compared to about 19 times that percentage lost through transpiration. Thus, the efficiency of water use by mature crops during early to mid spring time of 1965 appeared to be quite high. Drainage from the extreme edges of the Delta contained a substantial component of light isotope water suggesting significant contribution from Nile River since the completion of the High Dam. This particular remark necessitates, however, further study for quantifying these sources.1 tab., 7 fig

  15. The national environmental radiation monitoring network in egypt. Vol. 1

    International Nuclear Information System (INIS)

    Post accident environmental pollution with radionuclides occurs at accident site, and also cross borders to affect distant localities. The situation in egypt present special importance regarding its position near asian near asian and european nuclear sites, israel in east, and libya in the west. Also, the present and future nuclear installations in egypt. Environmental base line monitoring data is essential knowledge in nuclear practices. For these reasons, the egyptian government took steps to set up a national response plan for dealing with inside and outside accidents. The key elements of the plan is the establishment of a national environmental monitoring network (NERMN) and a nuclear emergency response system (NERS). The NERMN will detect radioactivity resulting from any accident affecting the egyptian territory even if it is not formally reported under international agreements, or if there are delays in notification. Therefore, the system provides the means of assembling and analyzing the radiological monitoring data related to the accident, and allowing information for the authorities. This is met with through a fully automatic system for gamma radiation monitoring and a semiautomatic system for air activity monitoring (aerosol), and network of liquid monitors. 4 figs., 1 tab

    2011-09-01

    Full Text Available A total of 75 sheep and goats from apparently healthy and from clinically affected flocks were examined for Coenurus cerebralis cysts from different localities in Egypt. Of 25 animals examined from clinically diseased sheep and goats, 25 (100% revealed the presence of infestation with one to four coenuri in the brain. The sites of predilection were the left hemisphere (48%, followed by the right hemisphere (40% and the cerebellum (12%. There was no apparent effect of the age of sheep and goats on susceptibility to infestation with C. cerebralis. Another 50 animals from apparently healthy sheep and goat herds presented no C. cerebralis cysts. The cysts from infested sheep could infest newborn puppies experimentally, with a prepatent period of 60 days post infestation. A total of 15 immature worms that were recovered from one puppy did not reach patency until 105 days post infestation with C. cerebralis cyst scolices. Pathological changes in C. cerebralis-infested sheep brain revealed parasitic elements, demyelinated nerve tracts, hyperaemic blood vessels with round cell infiltration, encephalomalacia with round cell infiltration and palisading macrophages and giant cells, as well as focal replacement of the brain parenchyma with caseated and calcified materials. The morphological characteristics of both the larval stage from sheep and goats and adult worms of Taenia multiceps from experimentally infested dogs are described. The results conclude that C. cerebralis is one of the principal causes of nervous manifestations of coenurosis in clinically diseased sheep and goats in Egypt.

    Full Text Available Background and Objectives: Few data are available on the level and sources of stress among law students in the Middle East generally and in Egypt specifically. We conducted this study to identify the prevalence and predictors of perceived stress among law students in Mansoura University, Egypt. Subjects and Methods: A cross-sectional study covered 426 law students selected through a stratified cluster sampling method. The questionnaire covered four categories, including 15 items on sources of stress (stressors. Perceived stress scale and Hospital anxiety and depression scale were used to measure stress, anxiety and depression.Results: A high level of perceived stress, anxiety and depression were reported by 42.2%, 59.2% and 18.2%, respectively. On the scale for sources of stress, 80% experienced personal troubles and two thirds of the sample had relationship, academic and environmental problems. Conclusions: It appears that the law students have a high level of perceived stress and majority of it is generated from personal factors and less from the academic or environmental factors. Additional studies are needed to improve our understanding of the causes and consequences of law students' stress.

    Full Text Available Ten polychlorinated biphenyl (PCB congeners were determined in water samples collected along the River Nile using gas chromatography-electron capture detector (GC-ECD. PCB concentrations ranged from 14 to 20 μg/L, which were higher than those reported in previous studies, indicating serious PCB pollution in the River Nile. PCB congener profiles varied depending on the sampling sties. PCB-138 was the predominant congener accounting for more than 18% of total PCBs. The composition of PCB congeners in the water revealed that highly chlorinated PCB technical mixtures such as Aroclor 1254 was the main PCB production historically used in Egypt. An increasing trend in PCB levels from the upper stream to the Nile estuaries was observed. The calculated flux of PCBs indicated that 6.8 tons of PCBs is dumped into the Mediterranean Sea each year from the River Nile. The hazard quotients and carcinogenic risk caused by PCB pollution in the River Nile were above the acceptable level indicating that PCBs in the River Nile water pose adverse health effects for all age groups. Our findings revealed that PCBs possess a serious risk to the Egyptian population that depends mainly on the River Nile as a source of water. Thus, stricter legislation and regulatory controls should be applied to reduce the risk of PCBs in Egypt.

    Full Text Available The free-living amoebae Acanthamoeba spp. have been recognized as etiologic agents of amoebic encephalitis, keratitis, otitis, lung lesions and other skin infections mainly in immuno-compromised individuals. The purpose of this study is to detect the presence of Acanthamoeba in swimming pools in Egypt using a polymerase chain reaction (PCR method.Water samples were collected from 10 different swimming pools in Cairo, Egypt. Samples were cultured on non-nutrient agar for the detection of Acanthamoeba isolates that were confirmed by PCR amplification using genus specific primers. The molecularly confirmed Acanthamoeba isolates were morphologically identified to the species level.Members of genus Acanthamoeba were detected in 49.2% of the examined swimming-pool water samples. Morphologically, six Acanthamoeba species were isolated from the examined swimming pool water namely A. polyphaga, A.castellanii, A. rhysodes, A. mauritaniensis, A. royreba and A. triangularis. All the identified species of Acanthamoeba were molecularly confirmed to be related to the genus Acanthamoeba.The isolated species of Acanthamoeba could provoke variable degrees of infections to the swimmers. The culture method is cheaper and easier than PCR techniques that are faster for the detection of free-living amoebae.

    Excessive amounts of mineral fertilizers are unnecessarily applied to agricultural soils in Egypt to increase crop yield. The current study aims at assessing the impacts of fertilization with different mineral fertilizers for different cultivation periods on the accumulation of heavy metals in soils and plants grown thereon. In addition, human risks resulted due to the exposure to these metal ions through ingestion, and dermal routes were evaluated. Soil and plant samples were collected from several locations in El-Behira Governorate, Egypt and their heavy metal contents were measured. The result indicated that there is a continuous accumulation of heavy metals in the soils and the plants grown thereon. Calculation of the hazard index (HI) revealed that humans, especially children, have a potential health risk for both Pb and Cd, which have levels greater than the safe level (1). Finally, the obtained results showed that the continuous application of mineral fertilizers containing high levels of heavy metals pose a potential health threat.

  1. Environmental-impact assessment of hydro-power in Egypt

    International Nuclear Information System (INIS)

    The environmental impact of energy production and use with the associated emissions of greenhouse gases, particularly CO2, has created much attention and growing concern at both national and international levels. In Egypt, efforts have been directed to incorporate the environment-protection issues within the overall planning of the energy sector, as appropriate to its national commitment and its techno-economic considerations. Over the past decade, 1985-1995, hydro-power had contributed between 28 and 22% of the total energy produced by Egyptian power-plants, while the contribution of the hydro capacity was between 32.4 and 21.5%. Many studies have been carried out on the impacts of the Aswan High Dam on various aspects of the environment. An objective evaluation of the Dam, based on 25 years of operational data, indicated that it has overall been positive even though it has contributed to some environmental problems. These problems, however, are significantly less than most people originally expected. This paper deals with the review and analysis of the detrimental effects of hydro-power in Egypt. An evaluation will be given of the emissions of greenhouse gases from the whole hydro-chain. (Author)

  2. Krypton-81 case study: the Nubian aquifer, Egypt. Chapter 14

    International Nuclear Information System (INIS)

    The Nubian aquifer of north-east Africa is one of the world’s largest fresh groundwater resources (∼150 000 km3). An area in the Western Desert of Egypt, for which a number of earlier studies provided sufficient background data on the Nubian aquifer, was selected for the first application of the atom trap trace analysis (ATTA) method (Section 5.4.3) for measurement of 81Kr in groundwater. This area has relatively simple geology, potential for containing very old groundwater, and favourable characteristics for comparison of the 81Kr and 36Cl methods (Sturchio et al. (2004)). Before this work, little evidence regarding absolute groundwater residence time in the N ubian aquifer was available. Estimates of groundwater age in the range of 0.54 × 106–1.58 × 106 a had been obtained from He/Ar ratios (Himida (1967) [729]). A large number of 14C data had been obtained for the Nubian aquifer waters in Egypt (Fröhlich et al. (2007) [730]; Sonntag et al. (1979) [731]). Chlorine-36 data indicated possible residence times of up to ∼9 × 105 a (unpublished data).

  3. Optimization of municipal solid waste management in Port Said - Egypt

    International Nuclear Information System (INIS)

    Optimization of solid waste management systems using operational research methodologies has not yet been applied in any Egyptian governorate. In this paper, a proposed model for a municipal solid waste management system in Port Said, Egypt is presented. It includes the use of the concept of collection stations, which have not yet been used in Egypt. Mixed integer programming is used to model the proposed system and its solution is performed using MPL software V4.2. The results show that the best model would include 27 collection stations of 15-ton daily capacity and 2 collection stations of 10 ton daily capacity. Any transfer of waste between the collection station and the landfill should not occur. Moreover, the flow of the district waste should not be confined to the district collection stations. The cost of the objective function for this solution is 10,122 LE/day (equivalent to US$1716). After further calculations, the profit generated by the proposed model is 49,655.8 LE/day (equivalent to US$8418.23)

    Arid soils in Egypt display large variability in solute transport properties, causing problems in soil management. To characterize this variability, dye infiltration experiments were conducted on four plots representing three main soil types in northeastern Egypt. The plots represented both cultivated and uncultivated land use. The observed dye patterns displayed a large variability and especially the clay soils indicated a high degree of preferential flow. The loamy sand and sandy soils displayed a more uniform dye distribution indicating more homogeneous soil properties. The observed dye patterns were modeled using a diffusion limited aggregation (DLA) model. The DLA is a random walk model where model parameters can be optimized using genetic algorithms (GA). The DLA model reproduced the observed dye patterns for all soils in an excellent way. The best fit was obtained with a specific combination of directional random walk probabilities Pu, Pd, Pr, and Pl for each plot (correlation 0.97-0.99). To account for soil layers with different hydraulic properties a two layer DLA model was developed. For all plots the Pu (upward random walk probability) was higher for the upper more homogeneous soil layer. The overall results showed that spatial variability resulting from solute transport for the investigated soils can be modeled using a DLA approach. PMID:25790463

    Using dead bodies for medical purposes has long been considered taboo in Egypt. Public health campaigns, physicians' pleas, and the urgings of religious scholars all failed to alter public opinion regarding the donation of dead bodies either for instructional material or for therapeutic treatments. Yet in 2011, amid revolutionary turmoil in Egypt, a campaign was launched for people to donate their eyes upon death; this time, people readily signed up to be donors. Focusing on mass eye trauma that occurred in Egypt amid the political uprisings of 2011, I raise questions about when and why Islam can explain people's attitudes and behaviors, particularly toward death and medicine. The case of mass eye trauma in Egypt and citizens' reformulations of questions once jealously controlled by state-aligned doctors, politicians, and religious scholars unsettles the boundaries between 'religion' and 'secularism' in medical practice.

    Full Text Available In Egypt, taxonomic aspects of the genus Pancratium L. (Amaryllidaceae, Pancratieae were thoroughly studied to point out the most reliable characters for taxon delimitation. Here, we base our species on both geographical and morphological features. The detailed taxonomic revision of genus Pancratium is based on field studies and the examination of representative specimens together with the authentic types deposited in the major herbaria of Egypt and Kew. Variations in the aerial scape, spathe, perianth, corona-teeth, pistil, stamens, capsules and seeds, as well as those of leaf base and leaf orientation are good markers to separate the different species. As a result, five species are recognized, including P. trianthum as a new record to the flora of Egypt. It is restricted to the south-eastern corner of Egypt (Gebel Elba region and being unique in possessing solitary spathe and long attenuate leaf base. A specific key and descriptions are given with typifications.

    The Nuqara volcanic is one of the northernmost outcrops of the Arabian-Nubian Shield Dokhan volcanics. The origin and tectonic setting of the late Neoproterozoic Dokhan volcanics (ca. 610-560 Ma) in the Egyptian Eastern Desert is highly debated. The debate concerns the tectonic setting where they formed during transition between convergent to extensional regime or after the East- and the West-Gondwana collision (~600Ma). In order to solve this problem, lavas from Nuqara area were studied geologically and geochemically. Nuqara Dokhan volcanics comprises two main rock suites: (a) an intermediate volcanic suite, consisting of basaltic andesite, andesite and their associated pyroclastics rocks; and (b) a felsic volcanic suite composed of dacite, rhyolite and ignimbrites. The two suites display well-defined major and trace element trends and continuum in composition with wide ranges in SiO2 (52-75.73%), CaO (9.19-0.22%), MgO (5.29-0.05%), Sr (1367-7.4 ppm), Zr (688.5-172.7 ppm), Cr (207-0.4 ppm), and Ni (94.3-0.2 ppm). The Nuqara Dokhan volcanics are characterized by strong enrichment in LILE relative to HFSE and affiliated to the calc-alkaline subducted - related magmatism. Geochemical Modeling displays that the evolution of these rocks was governed by fractional crystallization of plagioclase, amphiboles, pyroxene, magnetite and apatite in the intermediate varieties and plagioclase, amphibole, magnetite, apatite and zircon in the felsic varieties. The obtained mineral chemistry of these volcanics reveals: (a) Plagioclase range in composition from An55 to An40 in basaltic andesite and from An39 to An24 in andesite. (b) Alkali feldspars have sanidine composition. (c) Clinopyroxenes have augite composition. The low Al2O3 contents (1.94-5.588 wt %) indicate that clinopyroxene crystallized at low - pressure conditions. (d) Amphiboles have magnesio- hornblende composition.
